It seems likely that haemorrhoidal illness is certainly one of the oldest ills identified to man arteriovenous graft buy 12.5mg microzide otc. Some would postulate that it was the results of man assuming the upright position. They were referred to within the writings of the traditional Egyptians, the ancient Greeks and the Hebrews. The centre of the medical and cultural world remained in North Africa across to North India the place, within the tenth century, El-Zahrawy wrote a 30-volume medical encyclopaedia that was to stay in use for the next 500 years. He described cautery within the remedy of haemorrhoids as the final word in surgical remedy. A year later, his Chirurgie Magna was written, during which he advocated ligation for piles (ficus). From the French faculty in Montpellier came Henri de Mondeville (1260�1320), who advised in opposition to operating for haemorrhoidal illness, and Guy de Chanliac (1300�1370), who reported the Arabian methods of cauterising piles. However, there was little development in both the understanding or treatment of haemorrhoidal disease through the Middle Ages, with the barber surgeons holding sway and treating most sufferers with potions, suction leeches and the occasional lancet. Eighteenth-Century Pioneers During this century, many of the debates have been about the relative deserves of excision, with its risk of bleeding and stenosis, and ligation, with its risks of gangrene and sepsis. Houston7 of Dublin reintroduced the Riverius methodology of topical nitric acid, however it proved dangerous. In 1869, Morgan first handled a affected person by injection of persulphate of iron into the congested anal cushions. Colles, also of Dublin, used the strategy in 1874, however at that time it was not extensively adopted in England. The history of anal sphincter spasm began early in the nineteenth century when it was first realised that painful disorders of the anus had been associated with a very tight sphincter. At this stage, remedy was directed towards both light stretching of the sphincter or its whole surgical division. Copeland9 advocated the usage of giant bougies in overcoming spasm and painful anal situations, as did Salmon. Despite this early enthusiasm for sphincterotomy, it was another hundred years before interest in internal anal sphincterotomy was revived by Eisenhammer, between 1951 and 1971. These embrace Miles,eleven who described the broad V-shaped excision of the perianal pores and skin and division of the pecten band. The closed haemorrhoidectomy technique stemmed from the submucosal haemorrhoidectomy of Petit12 and Cooper6 talked about earlier. The method that was and is most widely used now may be that introduced by Blanchard and Alright. Blaisdell, in a scientific exhibit at the American Medical Association at Nineteenth Century: the Birth of Proctology Samuel Cooper (1809)6 developed the concepts of Petit, performing submucosal dissection before ligating the bottom of piles. Non-excisional and conservative strategies, such as clamp and cautery, that had been in use for lots of centuries were revived in 1846 by Cusack from Dublin and von Langenbeck in Germany in 1870. After a crushing clamp was positioned longitudinally alongside the size of the vascular cushion, the redundant cushion was excised and the tissue coagulated with a sizzling iron. Ireland appears to have turn into the centre for this kind of conservative management of haemorrhoidal illness in 202 Chapter 11 Haemorrhoidal Disease San Francisco in 1954, first revealed his instrument for the office ligation of inside haemorrhoids utilizing a silk ligature to the insensitive base of the vascular cushion. Infrared photocoagulation was used in the administration of haemorrhoidal disease following the development of an infrared coagulator by Nath et al. Since it could limit the expansibility of the anal orifice and be liable for some of the haemorrhoidal symptoms, the division or destruction of the band for a time became the cornerstone for therapy. Thus Lord,20 in his reintroduction of the Maisonneuve procedure, careworn the importance of disrupting this band. Eisenhammer21 believed that its division was central to all management of painful anal circumstances. Notarus22 divided it within the lateral subcutaneous sphincterotomy and claimed its division cured both painful haemorrhoids and fissure. Because of the risks of incontinence, strategies designed to stretch or incise the pecten band for the remedy of haemorrhoids have now been deserted. A extensive variety of remedies at the moment are out there for haemorrhoidal illness, starting from advice on diet and bowel behavior, via numerous non-operative methods of mucosal fixation, to a host of various techniques of excision of the inner anal vascular cushions and the external vascular channels. The choice of methodology is dependent upon the severity and type of the symptoms, on the degree of prolapse and on the experience of the operator and equipment obtainable. The artwork of the follow of proctology is to match the therapy to the degree of the illness in the affected person being handled. Other life-style modifications similar to improving anal hygiene, taking sitz baths, increasing fluid intake, relieving constipation and avoiding straining are used in main care and should assist in the treatment and prevention of haemorrhoids, though the proof for that is lacking. For the trendy proctologist, conservative forms of remedy past advice at the moment are so protected that a trial of advice alone is seldom justifiable. A detailed defaecation history should be taken from patients, and they want to be given recommendation concerning the disadvantages of any habits considered unwise. Diet Manipulation A high-fibre food regimen and the addition of bulking brokers (sterculia, ispaghula husk, psyllium seed extract and methylcellulose in a selection of pharmaceutical preparations) are a protected and logical first line of therapy. Meta-analysis has demonstrated that fibre dietary supplements versus placebo reasonably enhance total signs (47% reduction) and bleeding (50% reduction) and ought to be beneficial at an early stage. Vasotopic Drugs Venotonics similar to flavonoids are a preferred therapy of haemorrhoids in continental Europe (especially France) and the Far East. They might enhance venous tone, cut back hyperpermeability and have anti-inflammatory results. Metaanalysis has proven reduction in overall signs (58%), bleeding (67%) and pain (26. Most include several elements, including topical anaesthetics, steroids and antiseptics. Long-term use of these brokers ought to be discouraged, notably steroid lotions, which Conservative Management of Haemorrhoidal Disease 203 can permanently harm or cause ulceration of the perianal pores and skin. A 10-mL ampoule of 5% phenol in almond or arachis oil is used to inject three mL into the base of every vascular cushion. This may be achieved by a big selection of strategies, together with ligation or suture, injection of an irritant sclerosant and creating an ulcer by strangulation, burning or freezing. All of those strategies have been tried from time to time, but some are actually thought-about obsolete. They are employed after preliminary proctosigmoidoscopy has established the analysis, having excluded a neoplasm or inflammatory bowel illness. In most instances, the remedy is applied through the proctoscope that was used for the ultimate diagnostic evaluation of the anal canal. Most generally, the affected person is handled in the left lateral position, but the procedure could be carried out in the knee-chest position or on a particular proctology desk. Technique An illuminated proctoscope is handed by way of the anal canal into the rectum and the obturator removed. If faeces then enter the tip of the proctoscope and obscure the view, these are finest eliminated by pushing a ball of cotton wool by way of the proctoscope and leaving it in position within the rectum. The proctoscope is withdrawn till the reddish mucosa adjustments to the purplish mucosa, indicating engorged underlying vascular cushions. If the affected person is aware of discomfort as the answer is injected, it signifies that the needle is either too close to the anal verge or too deep. The fibrosis or scarring prevents or minimises prolapse of the cushions via or into the anal canal throughout defaecation. In the normal topic and within the patient with haemorrhoidal illness, the mucosa and muscularis mucosae of the decrease rectum and higher anal canal are only loosely adherent to the underlying round muscle coat and can simply be prolapsed into the lower anal canal. The rationale of mucosal fixation is an try and abolish or diminish this laxity. This is finished to stop the submucosal vascular cushions prolapsing into or through the anal canal throughout defaecation. Injection Sclerotherapy Equipment Purpose-designed disposable syringes and needles, based mostly on the unique design of Gabriel, are used to carry out the eleven. If the injection is merely too superficial, a totally avascular bleb is raised, as with an intradermal injection. The needle is withdrawn and the manoeuvre repeated in the right anterior and proper posterior positions. Particular care must be taken when injecting near the midline anteriorly because of the proximity of the prostate and the urethra in the male and the vagina in the feminine. Complications these embody pain from a badly sited injection or from submucosal extravasation, haemorrhage from the puncture level and less generally native sepsis. Lower urinary tract sepsis, local infections, prostatitis, portal pyaemia and erectile dysfunction have been reported.
In a retrospective examine heart attack 22 microzide 25 mg, Bokhari and Lindsey noticed incontinence in 37 p.c of their patients who underwent a fistulotomy for a posh fistula (high transsphincteric or compromised low transsphincteric). Major incontinence to solids was observed in thirteen percent and minor incontinence in 24 p.c of the patients. After fistulotomy for a simple fistula (non-compromised low transsphincteric or intersphincteric), major and minor incontinence was noticed in 5 and 11 percent of the sufferers, respectively. In 537 sufferers with a low anal fistula (mainly intersphincteric and low transsphincteric), a fistulotomy was performed. The long-term end result regarding faecal Treatment of Anal Fistulas 185 continence might only be assessed in 340 sufferers. Major incontinence (Vaizey rating higher than 6) was observed in 28 % of the patients. According to another Dutch research, fistulotomy is the strongest risk issue for deterioration of continence by which the severity of incontinence will increase with the complexity of the fistula. One would anticipate that these findings would mark the end of fistulotomy, a minimum of for prime transsphincteric fistulas. There continues to be an ongoing debate on the security of fistulotomy for transsphincteric fistulas. Atkin and colleagues reviewed 99 sufferers with a cryptoglandular anal fistula who underwent fistulotomy. The distinction between low and high fistulas was based totally on scientific grounds alone as a outcome of preoperative imaging was not performed within the majority of sufferers. During fistulotomy for high fistulas, 1�2 cm of cephalad contracting muscle was left intact. Impaired continence was observed in 25 p.c of these with a low fistula, in contrast with 36 % of the patients with a excessive fistula. It is well known that faecal incontinence might worsen over time as the capability of compensatory mechanisms declines. Furthermore, imperfect management of fuel and soiling can have a substantial detrimental impact to quality of life. Ultrasonography was carried out to quantify the longitudinal division of both the internal and external anal sphincter and to correlate the results with post-operative faecal incontinence. A easy fistula was defined as an intersphincteric fistula or a transsphincteric fistula involving lower than sixty six % of the total size of the external anal sphincter. Overall, there was no vital distinction in continence scores earlier than and after fistulotomy. However, 20 percent of the sufferers in whom 50�66 percent of the external anal sphincter was concerned encountered continence disturbances. Although this small series does counsel that fistulotomy is secure in chosen sufferers, it additionally illustrates that the danger of impaired continence will increase with the amount of external anal sphincter concerned. The debate concerning the protection of fistulotomy for transsphincteric fistulas is far from over, as evidenced by the recent online publication of a prospective multicentre examine from France. A two-stage fistulotomy, after preliminary insertion of a seton, was carried out in sixty two sufferers with a high transsphincteric fistula. Data have been collected utilizing a self-administered questionnaire before surgery, during follow-up and one 12 months after the process. After the one-stage fistulotomy, the overall improve in the median Wexner and Vaizey scores was negligible, whereas the general improve in median incontinence scores was barely larger after the two-stage fistulotomy. However, a Wexner score of over 10, normally affecting high quality of life, was present in thirteen p.c of the patients after the two-stage procedure. The question is whether or not this determine reflects reality, since sufferers with complex fistulous tracts or horseshoe extensions and people and not utilizing a detectable inner opening have been all excluded from this research. It is clear that the reported incidence of incontinence after fistulotomy varies extensively, mainly due to different affected person selection, completely different definitions of incontinence and variable follow-up. Validated incontinence scales are often not used to assess continence disturbances. Moreover, in most of the research, the choice to perform a fistulotomy was primarily based mostly on clinical grounds and never on preoperative imaging. This is compounded by the tools currently used for assessing continence, as the scores are designed to assess overall faecal incontinence and never the actual defects, corresponding to gutters inflicted by fistula operations during which soiling and imperfect control of flatus dominate. Therefore, one ought to always bear in mind the progressive trade-off between the extent of sphincter division and functional compromise against cure of the fistula itself. Considering all these features, it seems advisable not to opt for a fistulotomy as the primary treatment of choice for transsphincteric fistulas. These figures point out that even the two-stage process is related to a considerable threat of incontinence if a subsequent lay open operation is undertaken. Cutting seton: the staged slicing seton approach has been used since ancient times. After initial free placement of the seton to establish drainage, the seton is tightened at common intervals. Gradual stress necrosis will lead to a stepwise division of the enclosed sphincters. As far as is known, this theoretical benefit has not been confirmed by post-operative imaging. Most reviews are primarily based on retrospective research reviewing medical records and are tough to examine. Time intervals between tightening and definitions of post-operative incontinence differ broadly from paper to paper. Despite the issue in evaluating all the reports, Ritchie and coworkers have been capable of calculate the risk of incontinence after chopping seton treatment for transsphincteric fistulas. Based on pooled information, derived from an extensive literature search, the average risk of impaired continence was found to be 20. They analysed 18 studies, together with 448 patients, and in contrast the studies the place the internal anal sphincter was preserved with those the place this was not carried out. The overall incontinence rate after chopping seton therapy with and with out preservation of the inner anal sphincter was discovered to be 5 and 25 percent, respectively. Although this review was limited by the low quality of evidence in the obtainable studies, it does counsel that preservation of the interior anal sphincter would possibly cut back the risk of impaired continence after chopping seton treatment. Thirty years ago, Parkash and coworkers have been the primary to describe immediate sphincter reconstruction after fistulotomy in an attempt to cut back the risk of impaired continence. The common duration of follow-up was 29 months and the mean rate of sphincter disruption was 2. Amongst the sufferers who had been completely continent previous to the process, the overall fee of degradation of continence (mainly minor incontinence) was 12. The information that emerged from this systematic evaluate do, suggest that fistulotomy with primary sphincter reconstruction is an effective strategy with a relatively low risk of continence disturbance. The query is whether or not this statement is justified, since a randomised controlled trial evaluating fistulotomy alone with the mixed method has never been carried out. Details concerning preoperative imaging, the presence of horseshoe extensions and related abscesses and the quantity of muscle divided are lacking. Despite its limitations, this evaluate signifies that fistulotomy with major sphincter reconstruction deserves more attention. Therefore, it appears sensible to go for a sphincter preserving technique as first treatment of transsphincteric fistulas. Flap restore: In 1912, Elting launched the transanal advancement flap repair for anal fistulas. During the last three decades, this type of restore gained recognition as a sphincter saving process. Later on, it was advocated to add superficial fibres of the interior anal sphincter to have the ability to strengthen the flap. Currently, this process is almost completely performed in sufferers with a high transsphincteric fistula, passing through the higher or middle third of the exterior anal sphincter. Those who favour this system argue that it ensures obliteration of the inner opening, thereby leading to fistula therapeutic with preservation of the external anal sphincter. Preferably, flap restore is carried out with the patient in inclined jack-knife place. It makes more sense to use a self-retaining retractor with elastic stay hooks (lone star) to be able to minimise sphincter injury. Using this sort of retractor, the distal a part of the anal canal is everted, thereby providing an excellent exposure. Because no blades are inserted into the anal canal, the inner anal sphincter is barely stretched.

This often lifepreserving intervention is definitely a trick that surgeons have plagiarised from the evolutionary catalog that allowed our ancestors to survive belly catastrophe via spontaneous enterocutaneous fistula formation. Whilst the history of stoma development is as fascinating as any tale of our surgical pioneers, it has been nicely coated elsewhere. Since then, techniques have been refined to minimise stoma-related morbidity and enhance longterm care and administration. In the current day, iatrogenic stoma formation is widespread but nonetheless stays a subject of scrutiny in terms of utilisation, method and management. Some stomas are unavoidable; others are formed after careful consideration of the dangers and advantages that a stoma can provide. The utilisation of stomas depends on an understanding of fundamental ideas, widespread sense and expertise. Maturation of the mucocutaneous junction with sutures then follows to facilitate 108 Types of Stomas 109 therapeutic. Whilst some danger factors for stoma problems are tough to optimise, the surgeon can play a task in improving stoma quality by way of good decision-making, appropriate preparation and beautiful approach. As with most belly surgical procedure, no two operations are ever really the same, because of the unique circumstances by which each is undertaken. The formation of an ostomy in a skinny patient having an elective operation may be a completely different story to that encountered in the hostile stomach of a morbidly overweight patient with pan-enteric oedema and dilatation. However, several fundamental principles should be thought of in stoma creation, with a view to facilitating the formation of an stoma of the best high quality. In addition, sufferers range considerably in the sort and elegance of clothing worn, particularly in relation to the belt stage. For instance, a large stomach pannus may turn out to be very depending on standing and be inaccessible to the patient for the purpose of equipment adjustments. Creases within the stomach wall typically disappear in the supine position, only to corrugate the peristomal pores and skin on standing or sitting. Preoperative counselling will also provide an opportunity to initiate the sufferers training in self-care and subsequently expedite this process throughout post-operative restoration. These preoperative periods must be built-in with these of equal importance that can happen within the post-operative interval. It should also be as far-off as possible from any previous belly wall incision. In such cases the stoma may be placed through the proper rectus muscle above the umbilicus however at a distance from the costal margin. Types of Stomas 111 gastrostomy, jejunostomy, ileostomy, appendicostomy, caecostomy and colostomy. An ostomy can be shaped utilizing an end of bowel, a loop of undivided bowel, two separate ends of bowel or by way of an intraluminal catheter. Terminal Stomas Stomas that are effectively changing the anal canal are formed from probably the most distal side of the gastrointestinal tract nonetheless obtainable for delivery. Common examples would be an finish colostomy following abdomino-perineal excision or an finish ileostomy after panproctocolectomy. By utilising the most distal side of obtainable bowel, the affected person will retain a larger diploma of digestive function. This not only improves dietary points but should also allow extra processing of the stoma effluent. However, the surgeon must additionally take into account the opposite ideas mentioned under in phrases of ensuring that the stoma will function well. For instance, a well-spouted ileostomy is often preferable to a colostomy of the ascending colon due to the liquid nature of the stoma output and the ensuing problems which might be encountered with peristomal skincare round a liquid colostomy output. The authors prefer the loop ileostomy, because it poses no threat to the colonic marginal artery and in our experience is simpler to shut. The current Clinical Practice Guidelines of the American Society of Colon and Rectal Surgeons would additionally favour the ileostomy. Quite often they will be matured in a pre-existing wound such as the lower aspect of a midline incision. They are often fashioned after bowel resection in emergency surgery when primary anastomosis is taken into account to be high danger. The surgeon can then either decide to shut off the distal limb (usually with the firing of a linear stapler) and leave it in the stomach or mature it as a mucous fistula. Whilst a mucous fistula does represent another stoma with its associated morbidity (hernia, prolapse, peristomal sepsis, etc. It can also facilitate the process of finding and making ready the distal limb for re-anastomosis at subsequent laparotomy for restoration of continuity. Catheter assisted ostomy corresponding to a tube appendicostomy, cecostomy or percutaneous ileostomy can also be utilized in a venting capacity. Diversion is usually used as a brief lived measure, corresponding to in the safety of a low pelvic coloanal anastomosis. In this example the loop maintains the potential for a reversal operation to be carried out via a simple peristomal incision, rather than via a full laparotomy.
The definitive solution is to refashion the stoma with excision of diseased intestine as applicable blood pressure chart over a day purchase microzide uk. Parastomal varices type as a outcome of portal hypertension and subsequent shunting between the veins of the gut and the abdominal wall. They are sometimes seen in patients with colitis and associated sclerosing cholangitis. They effect up to 5% of sufferers with a stoma and coexisting portal hypertension of any aetiology. Whilst some could manifest as a basic parastomal Caput medusa, most are solely evidenced by recurrent bleeding. Bleeding tends to current either as a generalised slow venous ooze from a congested stoma or as a spurting high strain venous bleed from a single varix. As with any variceal bleeding, this does have the potential to be of a life-threatening magnitude. As with oesophageal varices, different local therapies similar to direct sclerosant injection can be employed. However, while native measures may provide temporary relief, re-bleeding is nearly inevitable (85%). Intransigent bleeding may require a disconnection of the mucocutaneous junction with under-running of the mucosal edge and ligation of the sub-mucosal veins. Trauma to the exposed mucosa by recurrent prolapse or a poorly fitted equipment can outcome in the formation of ulceration or excessive granulation tissue. It should at all times be considered that the purpose for the bleeding is a extra proximal pathology. In the big bowel this could be neoplastic, and patients must be investigated as one would in anyone presenting with rectal bleeding. Massive haemorrhage can usually be managed by under-running the vessel after disconnecting the mucocutaneous junction (not shown). Peristomal Dermatitis Peristomal dermatitis is most often a mechanical phenomenon related to the repeated pores and skin trauma attributable to equipment becoming and removal. However, if denuded skin does develop, an software of pores and skin sealant or a drying agent similar to calamine could shield the pores and skin and permit pouch utility to continue. Fungal an infection, bacterial folliculitis or an allergic response to adhesive can also produce parastomal dermatitis. Allergies to stoma adhesive are uncommon but should be suspected if the pores and skin response is confined to the realm of the bottom plate. Changing the appliance system will normally resolve the problem, but topical steroids could also be required to get on top of the preliminary reaction. It can mimic easy contact dermatitis in its indolent kind, producing erythema and communicating undermined serpiginous ulcers. However, it could manifest as acute ulceration with rapid onset tissue necrosis, suppuration, fever and ache. Nicorandil Multiple case reviews and series indicate that an identical picture of parastomal ulceration and fistulation may be related to the use of nicorandil. Alternatives can be found, and cessation of nicorandil therapy should subsequently be thought-about. Nicorandil ulcers will generally heal within eight to 12 weeks of stopping the drug. Despite these findings, serum iron and iron Parastomal Pyoderma Gangrenosum this often-painful entity is fortuitously rare. The regular losses through a healthy ileostomy are within the range of 600�640 mL/day and the whole loss of sodium is 70�80 mmol/day. Normal topics excrete only 150 mL of water a day and the sodium content of faeces is less than 5 mmol/day. As a result, the kidney conserves sodium at the expense of potassium, which is misplaced in excess, resulting in a low urinary sodium/potassium ratio (see Table 8. There is an extra loss of potassium from the ileostomy in change for sodium and water. The quantity and whole losses of sodium and potassium were a lot higher after small bowel resection111 and have been proportional to the extent of resection. However, there was elevated retention of orally administered iron and low ferritin levels, indicative of a gentle iron deficiency anaemia. It is suggested, subsequently, that ileostomy sufferers should be given prophylactic iron from time to time to correct this abnormality. By contrast, absorption was increased in sufferers with ulcerative colitis who had an ileostomy. Note: Normal: 24 h quantity urea, creatinine, creatinine clearance, calcium, phosphate. Fluid and Electrolyte Deficiency Ileostomy sufferers have significantly larger values for serum proteins, albumin and alkaline phosphatase than controls. It was concluded that the increased serum protein values reflected a state of gentle dehydration. Despite this, earlier studies of aldosterone levels in ileostomy patients revealed normal values. These data solid some doubt on the idea that ileostomy sufferers are in a state of chronic dehydration. There seems to be little doubt that patients with an ileostomy are also nutritionally depleted257 and that fats malabsorption happens even after minimal small bowel 1000 resection,127 presumably because of impaired bile salt absorption and a discount in the bile salt pool. Moreover, patients having massive small bowel resection compensate by consuming extra calories. Codeine, Lomotil and electrolyte dietary supplements minimise the fluid and electrolyte losses in ileostomy patients. Serum calcium, vitamin D138 and urinary calcium levels are usually regular in ileostomy patients with stones. However, excessive uric acid ranges have been reported,forty six,61 and this presumably is the cause for the excessive incidence of uric acid stones in these patients. Although radiolucent stones may be more common, a high proportion of renal stones in ileostomy patients include calcium and are radio-opaque. The mean 24-hour urinary sodium and magnesium ranges are low in ileostomates, so one other mechanism might operate to enhance the chance of urolithiasis. In the colon, malabsorbed fatty acids combine with calcium oxalate, leaving free oxalate out there for absorption. The issues that come up in revision are primarily the same as these encountered in parastomal hernia restore and are detailed above. Whilst native procedures via the original trephine site are possible, they might restrict the entry required to mobilise the bowel adequately. The refashioned stoma can also be vulnerable to hernia formation as is skilled in native repairs of a parastomal hernia. Quite often the pores and skin defect following local mobilisation is enlarged and makes formation of the mucocutaneous junction troublesome. The pores and skin defect could be reduced by utilizing the Mercedes manoeuvre or by a circumferential subcuticular purse-string suture. As with hernia repair, laparotomy or laparoscopy and transposition via an as but intact abdominal wall with prophylactic mesh reinforcement may be required. If a loop stoma is being refashioned, the surgeon ought to contemplate converting the stoma to an end ostomy if that is potential. Only in patients with an ileal resection of greater than 10 cm was there an increased incidence of gallstones (Table eight. This statement is as expected, since ileal resection results in lack of bile salts and a discount in the measurement of the bile acid pool, which adversely impacts cholesterol solubility. This bile acid deficiency is secondary to ileal malabsorption of bile acids and a discount within the bile acid pool. Clinical examination, notably rectal examination, ought to be used to exclude stenosis, which must be handled previous to closure. Sigmoidoscopy ought to exclude stricture, fistula or severe residual illness, all of which can contraindicate ileostomy closure.
