The continent ileostomy: long-term durability and patient satisfaction

Conversion of Failed J-Pouch to Kock Pouch: Indications, Contraindications, and Outcomes

BACKGROUND

The IPAA has been successful in restoring intestinal continuity and preserving continence in the majority of patients requiring a proctocolectomy. However, a subset of individuals experience significant complications that might result in pouch failure. The conversion of the J-pouch to a continent ileostomy pouch represents a significant surgical procedure. In this article, we discuss the indications and contraindications, present the technical principles applied for the conversion, and describe the outcomes of such conversion in the literature.

OBJECTIVE

The main objective during the conversion of the J-pouch to a continent ileostomy is the creation of a sufficiently sized reservoir with a high-quality valve mechanism while preserving as much small bowel as possible.

CONCLUSIONS

The conversion of the J-pouch to a continent ileostomy represents a significant surgical procedure. When performed in centers of expertise, it can be a good option for patients who otherwise will require an end ileostomy. Indications for conversion include most cases of J-pouch failure, with a few important exceptions. See video from symposium .

Reoperations and Long-term Survival of Kock's Continent Ileostomy in Patients With IBD: A Population-Based National Cohort Study From Sweden

BACKGROUND

Kock's continent ileostomy is an option after proctocolectomy for patients not suitable for IPAA or ileorectal anastomosis. Ulcerative colitis is the most common indication for continent ileostomy.

OBJECTIVE

The aim of this study was to evaluate the long-term outcome of continent ileostomy.

DESIGN

Retrospective cohort register study.

SETTINGS

Data were obtained from the Swedish National Patient Registry.

PATIENTS

All patients with IBD and a continent ileostomy were identified. Data on demographics, diagnosis, reoperations, and excisions of the continent ileostomy were obtained. Patients with inconsistent diagnostic coding were classified as IBD-unclassified.

MAIN OUTCOME MEASURES

The main outcome measures were number of reoperations, time to reoperations, and time to excision of continent ileostomy.

RESULTS

We identified 727 patients, 428 (59%) with ulcerative colitis, 45 (6%) with Crohn's disease, and 254 (35%) with IBD-unclassified. After a median follow-up time of 27 (interquartile range, 21-31) years, 191 patients (26%) never had revision surgery. Some 1484 reoperations were performed on 536 patients (74%), and the median number of reoperations was 1 (interquartile range, 0-3) per patient. The continent ileostomy was excised in 77 patients (11%). Reoperation within the first year after reconstruction was associated with a higher rate of revisions (incidence rate ratio, 2.90; p < 0.001) and shorter time to excision (HR 2.38; p < 0.001). Constructing the continent ileostomy after year 2000 was associated with increased revision and excision rates (incidence rate ratio, 2.7; p < 0.001 and HR 2.74; p = 0.013). IBD-unclassified was associated with increased revisions (incidence rate ratio, 1.3; p < 0.001)' and the proportion of IBD-unclassified patients almost doubled from the 1980s (32%) to after 2000 (50%).

LIMITATIONS

Retrospective design, data from a register, and no data on quality of life were available were the limitations of this study.

CONCLUSION

Continent ileostomy is associated with substantial need for revision surgery, but most patients keep their reconstruction for a long time. See Video Abstract at http://links.lww.com/DCR/C122 .

Construction of and Conversion to Continent Ileostomy: A Systematic Review

BACKGROUND

Continent ileostomy was first introduced by Nils Kock in 1969 as Kock pouch (K-pouch). Its most characteristic feature, the nipple valve that offers continence' was a later addition. Even though today's continent ileostomy is sidelined by ileal pouch-anal anastomosis as the gold standard of restorative procedures for colectomy patients, it remains an excellent option for select patients, offering an alternative to end-ileostomy or a poorly functioning ileoanal pouch.

OBJECTIVE

The study aimed to summarize principles and techniques behind K-pouch construction, both de novo and as "J to K" conversion, as well as examine surgical outcomes following the procedure in the modern era regardless of indication.

DATA SOURCES

Data sources included PubMed and the Cochrane Library up to July 2021.

STUDY SELECTION

The study selection materials included articles reviewing continent ileostomy procedures and outcomes between 2000-2021. Case reports and series <15 were excluded.

RESULTS

Fifteen articles were selected for review, describing 958 patients with a K-pouch, 510 patients who had undergone a Barnett continent intestinal reservoir, and 40 who had undergone construction of a T-pouch.

CONCLUSION

Continent ileostomies carried out in specialized centers by experienced surgeons can be a great option for patients who would otherwise be confined by an end ileostomy. High pouch survival rates with higher quality-of-life scores than end ileostomy and comparable with IPAA make continent ileostomy a great option, even if we consider the less than ideal reoperation and complication rates. However, it is of paramount importance that patients are carefully selected, thoroughly educated, highly motivated, and engaged in their care. Specifically, for patients with Crohn's disease, further research is needed to help elucidate factors that affect pouch survival and candidacy for K-pouch creation. Finally, continuous surgical technique modifications and refinements can allow even more patients to be considered suitable for the procedure.

Don't Forget about the K-Pouch!

The continent ileostomy (CI) was popularized by Nils Kock as a means to provide fecal continence to patients, most commonly in those with ulcerative colitis, after proctocolectomy. Although the ileal pouch-anal anastomosis (IPAA) now represents the most common method to restore continence after total proctocolectomy, CI remains a suitable option for highly selected patients who are not candidates for IPAA or have uncorrectable IPAA dysfunction but still desire fecal continence. The CI has exhibited a fascinating and marked evolution over the past several decades, from the advent of the nipple-valve to a distinct pouch design, giving the so-inclined and so-trained colorectal surgeon a technique that provides the unique patient with another option to restore continence. The CI continues to offer a means for appropriately selected patients to achieve the highest possible quality of life (QOL) and functional status after total proctocolectomy.

Long-term outcome and quality of life after continent ileostomy for ulcerative colitis: A systematic review

AIM

The continent ileostomy allows evacuation of an ileal reservoir at a time convenient to the patient. It is a surgical option for patients with ulcerative colitis (UC) when a restorative option is not suitable or has not succeeded and the patient does not want a conventional end ileostomy. Continent ileostomy types include the Kock pouch, Barnett continent intestinal reservoir and T-pouch. All of the published evidence on the long-term outcome and quality of life after continent ileostomy for UC was systematically reviewed.

METHODS

A systematic review was performed in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies published between 1990 and 2020 were included. A descriptive synthesis was used due to the clinical heterogeneity.

RESULTS

The search returned 1655 abstracts and after screening of abstracts and full text review, 19 were included in the final review, involving 1602 patients. Operative mortality is low (0%-3.6%) after all types of continent ileostomy but reoperation rates are high (20.8%-65%) because of valve mechanism failures. Rates of fistulae (0%-25.5%) and stomal stenosis (0%-25%) can be relatively high postoperatively. Quality of life scores improve for most patients undergoing continent ileostomy, especially for patients converted from ileal pouch anal anastomosis. Overall, continent ileostomy retention is high in the long-term.

DISCUSSION

In the long-term, patients report high satisfaction and a good quality of life with continent ileostomy, despite high reoperation rates and complications. Newer technologies may reinvigorate interest in the continent ileostomy for this population.

Long-term Follow-up, Patient Satisfaction, and Quality of Life for Patients With Kock's Continent Ileostomy

BACKGROUND

Continent ileostomy is a solution for patients after proctocolectomy.

OBJECTIVE

The aim of this study was to assess the long-term complications and failure rate alongside patient satisfaction, function, and quality of life for patients with a continent ileostomy.

DESIGN

This was a retrospective, descriptive cross-sectional study.

SETTINGS

All patients were operated in 1 center between 1980 and 2016.

PATIENTS

A total of 85 patients received a de novo continent ileostomy in our institution. Sixty-nine patients (80%) had ulcerative colitis, 12 (14%) had Crohn's disease, 2 had indeterminate colitis, and 1 each had familial adenomatous polyposis and anal atresia.

MAIN OUTCOME MEASURES

Medical charts were reviewed for reoperations and pouchitis. The 36-Item Short Form, Short Health Scale, and a local continent ileostomy questionnaire were used to assess quality of life, function, and satisfaction.

RESULTS

After a median follow-up of 24 years, 67 patients (79%) underwent a total of 237 reoperations, of which 15 were conversions to end ileostomies, that is, failures. Fifty patients (59%) underwent repeat laparotomies, excluding loop ileostomy closures. Nipple detachment was the most common cause for repeat laparotomy, and fistulation was the most common cause for pouch removal. IPAA before continent ileostomy was associated with an increased risk for failure. Crohn's disease was not associated with an increased risk for reoperation or failure. Forty-three patients (84%) reported that they were satisfied. Seventy patients were available for questionnaires, and 50 patients (71%) answered. There was no difference in the 36-Item Short Form between the continent ileostomy population and an age-matched control population.

LIMITATIONS

The retrospective, single-center design of the study alongside <100% response rate are to be considered limitations.

CONCLUSIONS

Despite large numbers of complications, patients are generally satisfied with their continent ileostomies, and their quality of life is comparable to the general population. See Video Abstract at http://links.lww.com/DCR/B444.

Continent Ileostomy as an Alternative to End Ileostomy

Continent ileostomy (CI) was once a prevalent surgical technique for patients who required total proctocolectomy but then gave way to ileal pouch-anal anastomosis (IPAA) after 1980. Although IPAA has been the gold standard procedure preferred by most patients when total proctocolectomy is required, due to its imitation of physiological function of rectum and preserved function of anus, various complications have been observed with a relatively high rate of morbidity that could affect pouch longevity. Once serious complications such as pelvic abscesses and/or fistula occur, the pouch often needs to be removed. In addition, for some patients with a shortened small intestine or foreshortened mesentery, it is impossible for the ileal pouch to reach the pelvic floor, thus making the creation of an IPAA difficult. Previously, most of these patients would be referred for an end ileostomy, with an associated poor quality of life. In this circumstance, we propose that CI may deserve a reappraisal and serve as an alternative. In this article, we review the indications, contraindications, technique evolution, and outcomes of CI.

The Association of Coloproctology of Great Britain and Ireland consensus guidelines in surgery for inflammatory bowel disease

AIM

There is a requirement of an expansive and up to date review of surgical management of inflammatory bowel disease (IBD) that can dovetail with the medical guidelines produced by the British Society of Gastroenterology.

METHODS

Surgeons who are members of the ACPGBI with a recognised interest in IBD were invited to contribute various sections of the guidelines. They were directed to produce a procedure based document using literature searches that were systematic, comprehensible, transparent and reproducible. Levels of evidence were graded. An editorial board was convened to ensure consistency of style, presentation and quality. Each author was asked to provide a set of recommendations which were evidence based and unambiguous. These recommendations were submitted to the whole guideline group and scored. They were then refined and submitted to a second vote. Only those that achieved >80% consensus at level 5 (strongly agree) or level 4 (agree) after 2 votes were included in the guidelines.

RESULTS

All aspects of surgical care for IBD have been included along with 157 recommendations for management.

CONCLUSION

These guidelines provide an up to date and evidence based summary of the current surgical knowledge in the management of IBD and will serve as a useful practical text for clinicians performing this type of surgery.

Is there still a role for continent ileostomy in the surgical treatment of inflammatory bowel disease?

The continent ileostomy (CI) was first described in 1969 as an important advancement in the surgical treatment of patients with ulcerative colitis, providing an option for fecal continence to patients who would otherwise require a conventional ileostomy. The CI enjoyed a brief period of relative popularity during the 1970s before being displaced by today's gold standard for the surgical treatment of ulcerative colitis, the restorative proctocolectomy (ileal pouch-anal anastomosis [IPAA]). Although the CI is only rarely performed today, it still has a role to play in the treatment of patients with inflammatory bowel disease who have failed medical treatment. Current indications are patients with failed IPAAs who are not candidates for redo-IPAA, patients who require total proctocolectomy but cannot be reconstructed with IPAA, and patients with an existing conventional ileostomy that is adversely affecting their quality of life. CI, however, is a complex procedure that carries significant risk of both postoperative complications and the need for reoperation over the long term due to slippage of the nipple valve. Patients being considered for this procedure should undergo extensive preoperative counseling and must have a thorough understanding of the associated risks and a realistic vision of anticipated benefits. In well-selected and properly motivated patients, however, CI can be durable in the majority with long-term pouch survival rates approaching 80%. Published data suggest that these patients enjoy greater quality of life than their counterparts with a conventional ileostomy and that 95% would choose to undergo the procedure again or recommend it to another.

Evolution of continent ileostomy

Continent ileostomy can be defined as a surgical procedure that facilitates planned intermittent evacuation of a bowel reservoir through an ileostomy. It was devised by Nils Kock in 1969. Subsequently, continent ileostomy (or Kock pouch) became a viable alternative in the management of patients who had traditionally required an end ileostomy. Kock pouch appeared to provide substantial physical and psychosocial benefits over a conventional ileostomy. The procedure became popular until ileal pouch anal anastomosis (IPAA) was introduced in 1980. Despite its benefits, continent ileostomy had many short term complications including intubation problems, ileus, anastomotic leaks, peritonitis and valve problems. Operative mortalities have also been reported in the literature. Most of these problems have been eliminated with increasing experience; however, valve-related problems remain as an “Achilles’ heel” of the technique. Many modifications have been introduced to prevent this problem. Some patients have had their pouch removed because of complications mainly related to valve dysfunction. Although revision rates can be high, most of the patients who retain their reservoirs are satisfied with regard to their health status and quality of life. Today, this procedure is still appropriate for selected patients for whom pouch surgery is not possible or for patients who have failed IPAA. Both the patient and their physician must be highly motivated to accept the risk of failure and the subsequent need for revisional operations.

T-pouch: results of the first 10 years with a nonintussuscepting continent ileostomy

BACKGROUND

Continent ileostomy is an alternative for patients who are either not candidates for an ileo-anal pullthrough or in whom an ileo-anal pullthrough failed. We previously described a new type of continent ileostomy (T-pouch) with a nonintussuscepting valve.

OBJECTIVE

This study performed an outcomes analysis of the first 10 years with 40 patients.

DESIGN

A prospective database of patients with a T-pouch from 2000 to 2010 was retrospectively analyzed.

MAIN OUTCOME MEASURES

The primary outcomes measured were demographics and surgical recovery information and the functional data obtained via questionnaire: incontinence, difficulty of pouch intubation, restrictions (work, social, diet, and sexual), quality of health and life, and level of satisfaction with surgery, which were rated on a scale of 0 to 10.

RESULTS

Twenty-three women and 17 men (mean age, 51.2) received a T-pouch. Median follow-up was 6.2 years (range, 0.8-11 years). Five patients (12.5%) experience a leak; 3 leaks were managed conservatively and/or with drain placement. Pouch intubations were done 4 times per day in a mean of 6.8 minutes; the insertion difficulty was rated as 2.5 of 10. Ninety-two percent achieved good continence. All quality-of-life and dysfunction/restriction scores showed significant improvement. Major abdominal surgeries for pouch-related reasons were needed in 30%; minor service operations of the skin-level stoma were needed in 25% of the patients. Of the patients, 87.5% would do the surgery again; 90% would recommend it to others with the same diagnosis.

LIMITATIONS

This study was limited by the cohort size and the lack of long-term data.

CONCLUSION

Ten years with 40 patients confirmed that creation of a T-pouch is complex but could be performed with an acceptable rate of complications. It dramatically improved functional outcomes; most notably, it improved fecal control and decreased social, sexual, and work restrictions.

The continent ileostomy: an alternative to end ileostomy? Short and long-term results of a single institution series

INTRODUCTION

Total proctocolectomy, ensuring eradication of all diseased colorectal mucosa is the treatment of choice for ulcerative colitis, familial adenomatous polyposis. Before the era of ileal pouch anal anastomosis, definitive ileostomy was required. The aim of this study is to define both early and late morbidity and the functional result of continent ileostomy.

METHODS

All patients' chart who had a continent ileostomy in our department were reviewed. The functional result was evaluated in 43 patients.

RESULTS

Forty-nine patients (34 women) with a mean age of 42 years (range: 17-69) underwent a continent ileostomy, 32 following a restorative proctocolectomy. The mean follow-up was 20.5 (range: 3-34) years. Seventeen patients (35%) experienced an early postoperative complication requiring reintervention in two patients. There was no mortality, and conversion to an end ileostomy was not required. Twenty-two patients developed late complications requiring 50 reoperations. The mean number of catheterisations per 24h was 4.4. The SF36 questionnaire showed values close to those of the general population.

CONCLUSION

Continent ileostomy carries a significant risk of non-severe complications. In selected patients, it represents a valuable alternative to an end ileostomy, in particular when restorative proctocolectomy has failed.

Morbidity and quality of life after continent ileostomy in the Netherlands

BACKGROUND

Continent ileostomy (CI) after proctocolectomy is an alternative technique compared to an ileal pouch-anal anastomosis (IPAA). The question arises as to whether this technique is valuable. The aim of this study was to evaluate the role of the continent ileostomy, by patient follow-up satisfaction and quality of life assessment.

METHOD

Twenty-eight patients with a continent ileostomy operated between 1996 and 2007 were compared with patients who received an IPAA or a conventional ileostomy. SF-36 and EORTC QLC-CR38 questionnaires and a specific continent ileostomy questionnaire were used to assess differences and patient satisfaction.

RESULTS

The quality of life in patients with a CI is not significant better or worse than patients with either a conventional ileostomy or an IPAA. On three scales (sexual enjoyment, gastro-intestinal tract symptoms and male sexual problems) statistically significant differences were reported. Overall, nearly all patients are very satisfied with the CI. All patients would make the same decision again and would recommend this procedure to other patients.

CONCLUSION

The continent ileostomy remains to be a suitable alternative for the preservation of continence after a proctocolectomy, especially when an ileal pouch-anal anastomosis is not an option. If a choice has to be made between a CI and conventional ileostomy good preoperative counselling is necessary to make a well founded decision. To minimize complications, these procedures have to be performed in centres with specific expertise. Therefore, knowledge about the CI should be preserved for the future.

Anal fistula plug in high fistula-in-ano: an early Saudi experience

PURPOSE

The Surgisis AFP anal fistula plug is a bioabsorbable xenograft designed to assist in the closure of anorectal fistulas. Its efficacy was studied in a series of patients at King Khalid University Hospital, in Riyadh, Saudi Arabia.

METHODS

Patients with chronic and/or complicated anorectal fistulas were prospectively studied. Diagnoses were made by clinical, radiographic, or endoscopic criteria. The number of fistula tracts (based on the number of primary openings) and the duration of draining setons was recorded. Under general anesthesia, patients underwent identification and irrigation of the fistula tracts using hydrogen peroxide. The anal fistula plug was used to occlude the primary opening for each high anal/anorectal fistula not amenable to fistulotomy. The plug was securely sutured into place at the primary opening using absorbable suture.

RESULTS

Twenty-two consecutive patients were prospectively enrolled. In total, 23 fistula tracts were treated. Three anorectal fistulas failed to close early in the study, but two failures were attributed to technical error. Both patients refused to undergo a second procedure. The third failure occurred because of recurrent Crohn's disease. After a mean follow-up of 12 months, 19 of the 23 fistula tracts remained successfully closed, for an overall success rate of 83%. There was no relationship between closure of the fistula and the presence of draining setons.

CONCLUSIONS

In our experience, closure of cryptoglandular anorectal fistula tracts using the Surgisis AFP anal fistula plug is safe and successful in 83% of fistula tracts at 12 months of follow-up.

Outcomes for patients undergoing continent ileostomy after a failed ileal pouch-anal anastomosis

PURPOSE

Continent ileostomy is considered an alternative for patients with a failed ileal pouch-anal anastomosis. The aim of this study is to investigate outcomes for patients undergoing continent ileostomy after a failed ileal pouch-anal anastomosis at our institution.

METHODS

Patients undergoing continent ileostomy after a failed ileal pouch-anal anastomosis were identified from a prospectively maintained pouch database. Quality-of-life scores were obtained by telephone follow-up or office visit and were determined by the Cleveland Global Quality of Life Score.

RESULTS

Sixty-four patients were identified between 1982 and 2007. Forty-two percent were male. The median age was 36.5 (range, 14-61) years. Most common diagnoses included ulcerative colitis (n = 44, 68.8%) and Crohn's disease (n = 13, 20.3%). The indication for continent ileostomy was septic pouch complications in 56.3% patients. The previous pelvic pouch was used in 16 (25%) patients. The 30-day complication rate was 31.3%. There were no perioperative deaths. Median follow-up was five years. The long-term dysfunction rate was 50%, the complication rate was 60.9%, and the revision rate 45.3%. The median revision-free interval was 2.8 years (range, 3 months to 19 years) and the retention rate of continent ileostomy was 95.3% (61 of 64). Median continent ileostomy survival time was 4.2 (range, 1-19) years. The median quality-of-life score was 0.77.

CONCLUSIONS

Continent ileostomy is possible in patients wishing to avoid an external appliance after pelvic pouch failure. Despite the associated morbidity, most of this select group of highly motivated patients retain their continent ileostomy long-term and are highly satisfied with their choice of continent ileostomy.

Endoscopic treatment for pill bezoars after continent ileostomy

Difficulty intubation is the most common long-term complication after continent ileostomy, which can be associated with nipple valve slippage, parastomal hernia, stenosis. Diagnosis and management of a patient with nipple valve stricture and partial bowel obstruction associated with dietary supplement retention in the pouch reservoir is described. A 50-year-old female patient with ulcerative colitis and a 15-year history of continent ileostomy after total proctocolectomy reported 5-week symptoms of abdominal pain and difficulty in intubating the pouch. Pill bezoar composed of dietary supplement was found in diagnostic pouch endoscopy. Therapeutic pouch endoscopy was performed with balloon dilation of a nipple valve stenosis and retrieval of 224 dietary supplement tablets. Pill bezoar in the pouch is rare. However, patients with continent ileostomy should be advised to avoid taking hard-to-dissolve foods and medications.

Delayed Kock pouch nipple valve failure: is revision indicated?

PURPOSE

This study was designed to review our experience with patients who, after more than 10 years of normal Kock pouch valve function, required repair of the valve. In addition, we describe the surgical techniques employed for valve repair.

METHODS

A retrospective chart review identified 31 patients who underwent Kock pouch revision after a minimum time interval between previous pouch surgery and the current revision of 10 (average, 19.7) years.

RESULTS

The intraoperative findings included slipped valve, valve prolapse, and internal nipple valve fistulas. The procedures performed included standard valve reconstruction, turnaround procedures, pedicle repair, wall stapling, and oversewing of fistula. Twelve of the 31 patients failed the initial revision and required additional operations, with an overall pouch salvage success rate of 93 percent. Only two patients required excision of the pouch and conversion to a Brooke ileostomy. The procedures were performed with minimal morbidity and no mortality.

CONCLUSION

Surgical revision can be offered to patients with a continent ileostomy complicated by delayed valve dysfunction with low morbidity and good functional outcome.

Surgical load and long-term outcome for patients with Kock continent ileostomy

OBJECTIVE

The aim of the study was to evaluate the results of Kock continent ileostomy (CI) during the same period when ileal pouch-anal anastomosis was the preferred operation for patients with ulcerative colitis (UC) or familial adenomatous polyposis (FAP).

METHOD

During the period 1983-2002, 50 patients underwent CI. The surgical technique was unchanged during the period. Follow-up included all patients. Forty-eight patients had UC, two of these had the diagnosis later changed to Crohn's disease and two had FAP.

RESULTS

Twenty-two patients had 38 reoperations, four (8%) of whom had the pouch removed. The main causes for reoperation included leakage and difficulty in intubation due to sliding of the nipple valve (42%), fistula formation (29%) and stenosis (21%). Seventeen (45%) underwent a revision of the nipple valve and the pouch and nine (24%) a local procedure. The reoperation rate was higher among patients having a conventional ileostomy converted to CI than among those having CI. As a primary procedure (P = 0.016). The risk of a second reoperation was higher for those reoperated within the first year after having a CI, than for those reoperated later (P = 0.007).

CONCLUSIONS

The reoperation rate of patients with CI is high but the removal rate of the pouch is low and is not associated with a high rate of revision. CI is a good alternative to conventional ileostomy in patients not suitable for restorative proctocolectomy or where this procedure has failed.

Elective and emergent operative management of ulcerative colitis

Surgical therapy of ulcerative colitis is effective, safe, and provides an improved quality of life in those whose disease cannot be managed medically. In the elective setting, widespread acceptance of restorative proctocolectomy has made surgical therapy an attractive option in the overall management of ulcerative colitis. Enthusiasm for this procedure should be tempered by the acknowledgment of the significant incidence of pouchitis in the long term, however. Proctocolectomy with ileostomy remains a good surgical option for patients who are unsuitable for restorative procedures. The standard therapy for fulminant colitis or toxic megacolon remains subtotal colectomy with ileostomy. Patients undergoing subtotal colectomy are candidates for conversion to restorative procedures.

Long-term outcome and quality of life after continent ileostomy

INTRODUCTION

This study was designed to evaluate long-term outcomes for patients undergoing Kock continent ileostomy, identify factors associated with adverse outcomes, and compare changes in quality of life after removal of the reservoir.

METHODS

The records of all patients (n = 330) undergoing continent ileostomy at the Cleveland Clinic Foundation between 1974 and 2001 were reviewed. Patient-related, intraoperative, and postoperative factors were evaluated as predictor variables of long-term pouch survival. Quality of life was evaluated using the continent ileostomy surgery follow-up questionnaire and the Cleveland Global Quality of Life scale (n = 216). These were compared between patients with continent ileostomy (n = 181) and patients who underwent removal of the continent ileostomy and conversion to an end stoma (n = 35).

RESULTS

The median patient follow-up was 11 (range, 1-27) years. The median revision-free pouch interval was 14 (95 percent confidence interval, 11-17) months. The 10-year and 20-year pouch survival was 87 and 77 percent, respectively. Patients had an average of 3.7(range, 1-28) complications and 2.9 (range, 1-27) pouch revisions during follow-up. On multivariate analysis, Crohn's disease (hazard ratio = 4.5), female gender (hazard ratio = 2.4), fistula development (hazard ratio = 3), and body mass index (hazard ratio = 2.4 per 5 unit increase) were independent predictors of pouch failure. Quality of life measurements for patients with a continent ileostomy were higher on all scales in comparison with patients who had the Kock reservoir and then reverted to a Brooke ileostomy.

CONCLUSIONS

Despite the associated morbidity with continent ileostomy surgery, long-term results and quality of life were encouraging. Continent ileostomy may be offered as an attractive long-term option to select patients whose only alternative is an end ileostomy.

Practice parameters for the surgical treatment of ulcerative colitis

The American Society of Colon and Rectal Surgeons is dedicated to assuring high-quality patient care by advancing the science, prevention, and management of disorders and diseases of the colon, rectum, and anus. The Standards Committee is composed of Society members who are chosen because they have demonstrated expertise in the specialty of colon and rectal surgery. This committee was created to lead international efforts in defining quality care for conditions related to the colon, rectum, and anus. This is accompanied by developing Clinical Practice Guidelines based on the best available evidence. These guidelines are inclusive, and not prescriptive. Their purpose is to provide information on which decisions can be made, rather than dictate a specific form of treatment. These guidelines are intended for the use of all practitioners, health care workers, and patients who desire information about the management of the conditions addressed by the topics covered in these guidelines. It should be recognized that these guidelines should not be deemed inclusive of all proper methods of care or exclusive of methods of care reasonably directed to obtaining the same results. The ultimate judgment regarding the propriety of any specific procedure must be made by the physician in light of all of the circumstances presented by the individual patient.

Health-related quality of life and pouch function in continent ileostomy patients: a 30-year perspective

PURPOSE

The principal aim of this study was to assess long-term pouch durability and health-related quality of life in an original series of patients operated on with a continent ileostomy.

PATIENTS

Data from 68 of 88 patients who had a continent ileostomy performed at Sahlgrenska University Hospital between 1967 and 1974 were analyzed. Median age at follow-up was 60 (range, 40-89) years and median follow-up was 31 (range, 29-36) years.

METHODS

Patients were sent a questionnaire on pouch function along with the Short Form-36 Health Survey 2.0. A random age-matched and gender-matched sample was drawn from the Swedish national Short Form-36 Health Survey norm database to compare with the patient group.

RESULTS

The majority of the patients reported good physical condition and satisfactory pouch function. Patients evacuated the pouch a median of four times every 24 hours. Twelve patients (18 percent) had leakages. Forty-four patients (65 percent) had had at least one postoperative revision to restore continence. Generally minor peristomal skin irritation occurred in seven patients (10 percent). Patients with concurrent complaints (mostly age related) reported poorer health-related quality of life. Nevertheless, 78 percent of the patients rated their overall health as good, very good, or excellent. The patients' Short Form-36 Health Survey scores were comparable to reference values.

CONCLUSIONS

Although revisional operations may be needed to restore continence, continent ileostomy has a good durability. Pouch function was satisfactory and patients' satisfaction was high. Health-related quality of life levels were similar to those of the general population.

Experimental model of continent colostomy using rectus abdominis neosphincteroplasty

Background

Use of dynamic myoplasty to create a continent stoma has produced promising results, but long-term stoma continence has not been achieved. The aim of the study was to establish and test a new model.

Methods

Three types of dynamic rectus abdominis sphincteroplasty around a colostomy and two conditioning protocols were tested in ten domestic pigs. Continence was assessed by means of conventional defaecography and neosphincter manometry after 8 and 12 weeks. The neosphincter muscle was studied histologically to assess the transformation of muscle type.

Results

Use of a distal rectus muscle sling surrounding the stoma by 270° with a low-frequency conditioning protocol achieved a continent colostomy for more than 12 h on each of 5 consecutive days. The neosphincter had a 40-mm high-pressure segment with mean pressure of 74 (range 67–82) mmHg. The proportion of type I muscle fibres increased from 38 (range 32–42) to 74 (range 66–78) per cent after 12 weeks of conditioning.

Conclusion

This pilot study demonstrated the feasibility of a continent stoma in an animal model with a dynamic rectus neosphincter. Long-term results should be confirmed in a larger series before use in humans can be considered.
