Outcomes of children with constipation and autism spectrum disorder treated with antegrade continence enemas.

BACKGROUND: Treatment of functional constipation (FC) in children with autism spectrum disorder (ASD) is challenging due to sensory and behavioral issues. We aimed to understand whether antegrade continence enemas (ACEs) are successful in the treatment of FC in children with ASD. METHODS: A single-institution retrospective review was performed in children diagnosed with ASD and FC who underwent appendicostomy or cecostomy placement from 2007 to 2019. Descriptive statistics regarding soiling and complications were calculated. RESULTS: There were 33 patients included, with a median age of 9.7 years at the time of ACE initiation. The average intelligence quotient was 63.6 (SD = 18.0, n = 12), the average behavioral adaptive score was 59.9 (SD = 11.1, n = 13), and the average total Child Behavioral Checklist score was 72.5 (SD = 7.1, n = 10). Soiling rates were significantly lower following ACE initiation (42.3% vs. 14.8%, p = 0.04). Behavioral issues only prevented 1 patient (3.0%) from proper ACE use. Eleven patients (36.6%) were able to transition to laxatives. There were significant improvements in patient-reported outcomes measures and quality of life. CONCLUSION: Placement of an appendicostomy or cecostomy for management of FC in children with severe ASD was successful in treating constipation and improving quality of life.

Long-Term outcomes of cecostomy tube insertion for patients with bowel dysfunction: A retrospective review.

BACKGROUND: Constipation is common in the pediatric population and in severe forms it can lead to debilitating fecal incontinence which has a significant impact on quality of life. Cecostomy tube insertion is a procedural option for cases refractory to medical management, however there is limited data investigating the long-term success and complication rate. METHODS: A retrospective review was performed evaluating patients at our centre undergoing cecostomy tube (CT) insertion between 2002 and 2018. The primary outcomes of the study were the rate of fecal continence at 1-year, and the incidence of unplanned exchanges prior to annual scheduled exchange. Secondary outcomes include the frequency of anaesthetic requirements and length of hospital stay. Descriptive statistics, t-test, and chi-square analysis was performed where appropriate using SPSS v25. RESULTS: Of 41 patients, the average age at the time of initial insertion was 9.9 years with the average length of stay in hospital being 3.47 days. The most common etiology of bowel dysfunction was spina bifida, which was present in 48.8% (n = 20) of patients. Fecal continence was achieved in 90% (n = 37) of patients at 1 year and the average rate of cecostomy tube exchange was 1.3/year with an average of 3.6 general anaesthetics being required by patients and the average age of no longer requiring one being 14.9 years. DISCUSSION: Analysis of patients undergoing cecostomy tube insertion at our centre has further supported the use of cecostomy tubes as a safe and effective option for management of fecal incontinence refractory to medical management. However, a number of limitations exist in this study including its retrospective design and failure to investigate changes in quality of life using validated questionnaires. Additionally, while our research provides greater insight to practitioners and patients what degree of care and types of complications or issues they may encounter with an indwelling tube over the long-term, our single-cohort design limits any conclusions that could be made regarding optimal management strategies for overflow fecal incontinence through direct comparison with other management strategies. CONCLUSIONS: CT insertion is a safe and effective method for managing fecal incontinence due to constipation in the pediatric population, however, unplanned exchange of tube due to malfunction, mechanical breakage, or dislodgment occurs frequently and may impact quality of life and independence.

Delivery routes for faecal microbiota transplants: Available, anticipated and aspired.

Fecal microbiota transplant (FMT) has seen a historic emergence in last decade with its sojourn recently entering into a chequered path, due to a few reports of infection and subsequent mortality. Though FMT has been extensively reported, there is no comprehensive report on the delivery routes available for this non-pharmacological treatment option. Safety, efficacy and cost of FMT not only depend on the quality of contents but also on the delivery route employed. A number of delivery routes are in use for conducting FMT, which include upper gastrointestinal routes (UGI) i.e. nasogastric/nasojejunal tube, endoscopy, oral capsules and lower gastrointestinal routes (LGI) like retention enema, sigmoidoscopy or colonoscopy. Capsules, both conventional as well as colon targeted have been the most commonly used formulations. Surprisingly, the success rates with conventional gastric delivery capsules and colon targeted capsules were found to be quite similar indicating the sufficiency of the inoculum size to withstand the microbial loss in the gastric milieu. Patient compliance, cost effectiveness, comfort of administration, level of invasiveness, patient's hospital admission, risk of aspiration and infections, multiplicity of administration required, recurrence rate are the main factors that seem to influence the choice for route of administration of physicians. The best route for FMT has not been established yet. Extensive studies are required to understand the interplay of route adopted, type of donor, physical nature of sample (fresh or frozen), patient compliance and cost effectiveness to design an approach for the risk free, convenient and cost-effective administration route for FMT.

Tube cecostomy versus appendicostomy for antegrade enemas in the management of fecal incontinence in children: A systematic review.

BACKGROUND: Few studies have directly compared between cecostomy and appendicostomy for the management of fecal incontinence in pediatric population. This systematic review of the literature describes outcomes and complications following both procedures. We also reviewed studies reporting impact on quality of life and patient satisfaction. METHODS: MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), and Google Scholar were searched for chronic constipation pediatric patients who underwent cecostomy or appendicostomy. Two reviewers independently screened studies, extracted data, and assessed quality. RESULTS: An initial literature search retrieved 633 citations. After review of all abstracts, 40 studies were included in the final analysis, assessing a total of 2086 patients. The overall rate of complications was lower in the cecostomy group compared to the appendicostomy group (16.6% and 42.3%, respectively). Achievement of fecal continence and improvement in patient quality of life were found to be similar in both groups, however the need for revision of surgery was approximately 15% higher in the appendicostomy group. CONCLUSION: Cecostomy has less post procedural complications, however rates of patient satisfaction and impact on quality of life were similar following both procedures. LEVEL OF EVIDENCE: III.

Anterograde colonic irrigations by percutaneous endoscopic caecostomy in refractory colorectal functional disorders.

PURPOSE: In case reports or small studies, percutaneous endoscopic caecostomy (PEC) has been proposed as an alternative to the Malone intervention to perform antegrade colonic enemas. Our goal was to assess the feasibility, efficacy, and tolerance of PEC in a large group of patients with refractory colorectal functional disorders. METHODS: From September 2006 to April 2014, all patients undergoing PEC for constipation, fecal incontinence, and incontinence after rectal resection in two expert centers were studied. The PEC procedure consisted in anchoring the caecum to the abdominal wall (caecopexy) and placing a specifically designed tube in the colonic lumen to perform antegrade enemas. The quality of life (GIQLI), constipation (Kess), and incontinence (Cleveland) scores were assessed before PEC and at 3, 6, 12, and 24 months. RESULTS: A total of 69 patients were included. GIQLI scores were significantly improved in constipation group (n = 43), incontinence group (n = 19), and rectal resection group (n = 10). In the constipation group, Kess score decreased from 25.9 before PEC to 20.6 at 2 years (p = 0.01). In the incontinence and post-rectal resection groups, Cleveland scores decreased from 14.3 before PEC to 2.7 at 6 months (p = 0.01) and to 10.4 at 2 years (p = 0.04). Overall, PEC was considered successful by patients in 58%, 74%, and 90% of cases, in constipation, incontinence, and rectal resection groups, respectively. Chronic pain (52%) at the catheter site was the most frequent complication. CONCLUSIONS: Percutaneous endoscopic caecostomy for antegrade colonic enemas improves significantly the quality of life of patients with colorectal disorder refractory to medical treatment.

Primary placement of a skin-level Cecostomy Tube for Antegrade Colonic Enema Administration Using a Modification of the Laparoscopic-Assisted Percutaneous Endoscopic Cecostomy (LAPEC).

PURPOSE: Children failing medical management for severe constipation and/or fecal incontinence may undergo surgical intervention for antegrade enema administration. We present a modification of the laparoscopic-assisted percutaneous endoscopic cecostomy (LAPEC) procedure that allows primary placement of a skin-level device. METHODS: A single-institution retrospective review was performed from 2009 to 2015. In the modified technique the colonoscope is advanced to the cecum, cecal suspension sutures are placed under laparoscopic visualization, and percutaneous needle puncture of the cecum is performed under direct laparoscopic and endoscopic visualization. A skin-level cecostomy tube is then placed over a guide wire. Patient characteristics and 30-day results were analyzed by Fisher's exact test. RESULTS: Fifty-two patients underwent attempted LAPEC. Successful LAPEC using both laparoscopic and endoscopic guidance was achieved in 46 (88.5%). A MIC-KEY device was placed in 38. Corflo PEG tube placement was necessary in 14 due to high BMI (mean 28.4). Colonoscopy failed to reach the cecum in 6 and laparoscopy alone was utilized to achieve successful tube placement. Cecostomy site infections occurred in 3 (5.8%), only in those undergoing PEG placement using a pull technique (p < 0.05). CONCLUSION: Primary placement of a skin-level device was successful in the majority of patients undergoing cecostomy tube placement for bowel management utilizing antegrade colonic enemas. This technique avoids a second anesthesia for tube conversion. Visualization via colonoscopy with the use of cecal suspension sutures is recommended. High BMI necessitates initial placement of a PEG tube and complications exclusively occurred in this group. TYPE OF STUDY: Clinical. LEVEL OF EVIDENCE: IV Case series study.

A comparison of Malone appendicostomy and cecostomy for antegrade access as adjuncts to a bowel management program for patients with functional constipation or fecal incontinence.

BACKGROUND: Appendicostomy and cecostomy are two approaches for antegrade enema access for children with severe constipation or fecal incontinence as adjuncts to a mechanical bowel management program. Each technique is associated with a unique set of complications. The purpose of our study was to report the rates of various complications associated with antegrade enema access techniques to help guide which option a clinician offers to their patients. METHODS: We reviewed all patients in our Center who received an appendicostomy or cecostomy from 2014 to 2017 who were participants in our bowel management program. RESULTS: 204 patients underwent an antegrade access procedure (150 appendicostomies and 54 cecostomies). Skin-level leakage (3% vs. 22%) and wound infections (7% vs. 28%) occurred less frequently in patients with appendicostomy compared to cecostomy. Nineteen (13%) appendicostomies required revision for stenosis, 4 (3%) for mucosal prolapse, and 1 (1%) for leakage. The rates of stenosis (33 vs. 12%) and wound infection (13 vs. 6%) were higher in patients who received a neoappendicostomy compared to an in situ appendicostomy. Intervention was needed in 19 (35%) cecostomy patients, 15 (28%) for an inability to flush or a dislodged tube, and 5 for major complications including intraperitoneal spillage in 4 (7%) and 1 (2%) for a tube misplaced in the ileum, all occurring in patients with a percutaneously placed cecostomy. One appendicostomy (1%) patient required laparoscopic revision after the appendicostomy detached from the skin. CONCLUSION: Patients had a lower rate of minor and major complications after appendicostomy compared to cecostomy. The unique complication profile of each technique should be considered for patients needing these procedures as an adjunct to their care for constipation or fecal incontinence. TYPE OF STUDY: Retrospective comparative study. LEVEL OF EVIDENCE: Level III.

No Appendix is Too Short-Simultaneous Mitrofanoff Catheterizable Vesicostomy and Malone Antegrade Continence Enema (MACE) for Children with Spina Bifida.

OBJECTIVE: To present the results of simultaneous creation of both Mitrofanoff stoma and Malone antegrade continence stoma (MACE) using simple division of the appendix and a cecal extension method. MATERIALS AND METHODS: Between June 2011 and November 2016, simultaneous Mitrofanoff and MACE was performed in 16 children (12 children-simple division of the appendix, 4 children-appendicovesicostomy and cecal extension of the appendix). Extension of the appendix was achieved by tubularization of the excised cecal flap next to the short appendicular stump. The new extended channel was then wrapped by cecal wall. RESULTS: Follow-up was 40 months (10-74 months). Currently, in all children, both stomas are easily catheterizable. Obstruction of MACE occurred in 5 children (4 with split appendix, 1 with extended appendix); Mitrofanoff stomal stenosis occurred in 1 child. Endoscopic revision and prolonged catheterization of stenotic stomas were effective in all cases. Wound infection and dehiscence was noted in 2 children (both with split appendix). Drainage and intravenous antibiotics were effective. All Mitrofanoffs are continent. In 4 children there is incident minor leakage of the MACE (3 with split appendix and in 1 with extended appendix). CONCLUSION: The split appendix procedure is feasible. Cecal extension of the appendix seems to be a good option when the appendix is too short for a simple split procedure.

Analysis of Factors Associated with Patient or Caregiver Regret following Surgery for Fecal Incontinence.

PURPOSE: Malone antegrade continence enema has been a successful and widely used procedure for achieving fecal continence in children. We present data on the previously uninvestigated issue of patient and caregiver regret following surgery for intractable constipation and fecal incontinence. MATERIALS AND METHODS: We reviewed all patients undergoing antegrade continence enema or cecostomy creation at a single institution between 2006 and 2016. Patients and caregivers were assessed for decisional regret using the Decisional Regret Scale. Results were correlated with demographics, surgical outcomes and complications. RESULTS: A total of 81 responses (49 caregivers and 32 patients) were obtained. Mean followup was 49 months. Decisional regret was noted in 43 subjects (53%), including mild regret in 38 (47%) and moderate to severe regret in 5 (6%). No statistical difference in regret was noted based on gender, complications or performance of concomitant procedures. On regression analysis incontinence was strongly associated with decisional regret (OR 4.4, 95% CI 1.1-18.1, p <0.001) and regret increased as age at surgery increased, particularly when patients were operated on at age 13 to 15 years (OR 2.6, 95% CI 1.0-6.4 for age 13 years; OR 2.9, 95% CI 1.1-7.8 for age 14 years; OR 3.1, 95% CI 1.1-8.8 for age 15 years). CONCLUSIONS: This is the first known study describing decisional regret following surgery for fecal incontinence. Surgical factors aimed at achieving continence may be effective in decreasing postoperative regret. The finding of increased regret in teenage patients compared to younger children should be shared with families since it may impact the age at which surgery is pursued.

Laparoscopic-Assisted Percutaneous Endoscopic Cecostomy (LAPEC) in Children and Young Adults.

OBJECTIVE: We evaluated the safety and efficacy of the laparoscopic-assisted percutaneous endoscopic cecostomy (LAPEC) procedure both in children and young adults, along with review of their pre-operative motility profiles, antegrade continence enema (ACE) regimen, and postoperative complications. METHODS: This retrospective review investigated 38 patients (32 children and 6 young adults) that underwent the LAPEC procedure. Primary outcomes evaluated were success versus failure of the procedure and post-operative complications. Success was defined as daily stool evacuation with minimal to no fecal incontinence per week. RESULTS: Mean follow up time was 25.8 ± 22.4 months. Indications for LAPEC included slow transit constipation or colonic neuropathy (n = 22), other types of constipation (n = 5), and a variety of congenital disorders (n = 11). The overall success rate was 95% (36/38 patients) with the two failures in children, both attributed to inability to use the tube due to underlying behavioral disorders or severe anxiety. Five patients above age 18 had leakage compared to 6 in the under age 18 group (83% vs. 19, P = 0.003). There were no other significant complications. CONCLUSION: LAPEC is a safe and effective means of addressing refractory constipation and fecal incontinence in children and young adults who have failed medical management with minimal post-operative complications.

Slowed relaxation of diaphragm in septic rats is associated with reduced expression of sarco-endoplasmic reticulum CA2+ -ATPase genes SERCA1 and SERCA2.

INTRODUCTION: The aim of this study was to study the effects of sepsis on diaphragm relaxation properties and the associated expression of sarco-endoplasmic reticulum Ca2+ -ATPase genes SERCA1 and SERCA2. METHODS: Rats were randomized to undergo either sham surgery or cecal ligation and puncture (CLP). Diaphragm isometric relaxation parameters were measured after 24 h. The mRNA expression and protein content of SERCA1 and SERCA2 in diaphragm muscles were determined. RESULTS: Both diaphragm maximal twitch and tetanus relaxation rates were reduced. Twitch half-relaxation time was prolonged after normalization to half of peak twitch tension. The mRNA expression and protein content of SERCA1 and SERCA2 were decreased. CONCLUSIONS: Slowed relaxation of the diaphragm in septic rats was associated with reduced expression of SERCA1 and SERCA2. Muscle Nerve 54: 1108-1113, 2016.

Percutaneous Cecostomy in Adult Patients: Safety and Quality-of-Life Results.

PURPOSE: To assess the safety and quality of life in adult patients undergoing cecostomy tube placement. MATERIALS AND METHODS: Percutaneous cecostomy was performed in 23 adults (10 men and 13 women) with neurogenic bowel for whom noninvasive therapeutic approaches for chronic refractory constipation or fecal incontinence had failed. Mean patient age was 41 years (range, 19-74 y). A retrospective, standardized questionnaire evaluated satisfaction and quality of life before and after cecostomy. RESULTS: All 23 cecostomy procedures were technically successful with no intraprocedural complications. At a mean follow-up of 42 months (range, 1-160 mo), there was one (5%) major complication, a pericecal abscess. One or more minor complications in 11 of 23 (48%) patients included leaking around the tube (5 of 23; 22%) and partial or complete dislodgment of the tube (3 of 23; 13%). In all cases, the cecostomy tube was exchanged successfully. Satisfaction scores improved from a mean of 2.2 points (range, 0-6 points; median, 1.5) to 7.6 points (range, 4-10 points; median, 8). The percentage of patients using laxative softeners decreased from 74% to 40%, and patients requiring assistance decreased from 52% to 35% after cecostomy placement. CONCLUSIONS: Percutaneous cecostomy is a safe procedure for the management of adult patients. Patients are able to achieve greater independence in their activities of daily living and are highly satisfied with the outcomes.

Safety and efficacy of percutaneous cecostomy/colostomy for treatment of large bowel obstruction in adults with cancer.

PURPOSE: To assess the safety and efficacy of image-guided percutaneous cecostomy/colostomy (PC) in the management of colonic obstruction in patients with cancer. MATERIALS AND METHODS: Twenty-seven consecutive patients underwent image-guided PC to relieve large bowel obstruction at a single institution between 2000 and 2012. Colonic obstruction was the common indication. Patient demographics, diagnosis, procedural details, and outcomes including maximum colonic distension (MCD; ie, greatest transverse measurement of the colon on radiograph or scout computed tomography image) were recorded and retrospectively analyzed. RESULTS: Following PC, no patient experienced colonic perforation; pain was relieved in 24 of 27 patients (89%). Catheters with tip position in luminal gas rather than mixed stool/gas or stool were associated with greater decrease in MCD (-40%, -12%, and -16%, respectively), with the difference reaching statistical significance (P = .002 and P = .013, respectively). Catheter size was not associated with change in MCD (P = .978). Catheters were successfully removed from six of nine patients (67%) with functional obstructions and two of 18 patients (11%) with mechanical obstructions. One patient underwent endoscopic stent placement after catheter removal. Three patients required diverting colostomy after PC, and their catheters were removed at the time of surgery. One major complication (3.7%; subcutaneous emphysema, pneumomediastinum, and sepsis) occurred 8 days after PC and was successfully treated with cecostomy exchange, soft-tissue drainage, and intravenous antibiotic therapy. CONCLUSIONS: Image-guided PC is safe and effective for management of functional and mechanical bowel obstruction in patients with cancer. For optimal efficacy, catheters should terminate within luminal gas.

Comparison of short- and long-term complications and survival following jejunojejunostomy, jejunoileostomy and jejunocaecostomy in 112 horses: 2005-2010.

REASONS FOR PERFORMING THE STUDY: There is disagreement among surgeons over whether jejunoileostomy (JI) or jejunocaecostomy (JC) is the better method of anastomosis following proximal ileal resection. OBJECTIVE: To compare short- and long-term complications and outcome in horses undergoing jejunojejunostomy (JJ), JI and JC and to test the hypotheses that a higher proportion of horses undergoing JI would have short-term complications and mortality compared with horses undergoing JC or JJ and that JC would be associated with a higher long-term mortality and occurrence of colic. STUDY DESIGN: Retrospective cross-sectional study. METHODS: Medical records of horses undergoing celiotomy for a small intestinal obstruction and JJ, JI or JC from 2005 to 2010 were reviewed. Post operative complications were recorded. Short-term outcome was alive vs. dead at hospital discharge and was analysed using a Chi-squared test. Long-term follow-up was obtained and a Kaplan-Meier estimate of the survivor function was performed. RESULTS: There were 112 horses included. A higher proportion of JI horses had a repeat celiotomy during hospitalisation compared with horses undergoing JC. The number of horses alive at hospital discharge was not different between groups: JJ 79% (95% confidence interval [CI] 68-90%), JI 78% (95% CI 61-96%), JC 83% (95% CI 71-96%). Among horses discharged with long-term follow-up, more horses had colic after JC compared with JJ or JI. Long-term post discharge survival based on the Kaplan-Meier survivor function was lower for horses undergoing JC than JJ or JI (P = 0.04). CONCLUSION: While there was no difference in short-term outcome between groups, more horses with JI underwent a repeat celiotomy during hospitalisation. Horses with a JC were more likely to have long-term complications with colic. Horses that were subjected to euthanasia because of colic within 12 months of hospital discharge either had a JC or repeat celiotomy. The results suggest that, when possible, a JI may be the preferred method of anastomosis based on more favourable survival and lower occurrence of colic long term.

Efficacy of protective tube cecostomy after restorative resection for colorectal cancer: a randomized trial.

BACKGROUND: The construction of colostomy is associated with decreased physical and psychological well-being as well as decreased quality of life. Cecostomy is the creation of an opening in the cecum to provide colonic decompression. OBJECTIVE: This work was conducted to evaluate the efficacy of tube cecostomy as an alternative to colostomy in the managing patients with left-sided colonic carcinoma and rectal cancer in terms of occurrence of postoperative morbidity and mortality and the functional outcome. DESIGN AND SETTINGS: A total number of 156 patients with colorectal cancer were enrolled in the study and were divided randomly into two equal groups. PATIENTS: A group of 78 patients underwent tube cecostomy (group A) were compared with the other 78 patients who underwent loop colostomy (group B). The outcome parameters were the incidence of anastomotic leak, operative time, primary operation mortality rate, patient satisfaction and hospital stay. RESULTS: The mean operating time and the mean hospital stay was significantly shorter in tube cecostomy group when compared with loop colostomy group (P < 0.05). The overall recorded morbidity for the primary operation was 12.8% and 29.5% for group A and B respectively [P ≥ 0.05] while the stoma related complications rate was 7.7% and 25.6% for each group respectively [P ≤ 0.05]. CONCLUSION: Performing tube cecostomy instead loop colostomy in managing patients with left-sided colonic carcinoma and rectal cancer can decrease the anticipated postoperative morbidity, lowers prolonged hospital stay and provides adequate functional outcome.

Laparoscopic-assisted percutaneous endoscopic cecostomy in children with defecation disorders (with video).

BACKGROUND: The antegrade continence enema (ACE) procedure has been widely used in the management of children with defecation disorders. The ACE procedure has undergone many technical modifications. We developed a safe and minimally invasive technique, the laparoscopic-assisted percutaneous endoscopic cecostomy (LAPEC). OBJECTIVE: To compare LAPEC to laparoscopic cecostomy in terms of operative time, hospital length of stay, and procedure-related morbidity. DESIGN: Retrospective review of children undergoing the ACE procedure. SETTING: Two tertiary-care centers. PATIENTS: This study involved children with defecation disorders. INTERVENTION: The ACE procedure. MAIN OUTCOME MEASUREMENTS: Procedure complications, length of stay, and operative time. RESULTS: Fifty patients underwent LAPEC, and 15 underwent laparoscopic cecostomy. Of the LAPEC patients, 70% were male, with mean age 12 ± 4.2 years, mean operative time 100.1 ± 16.6 minutes, and mean length of stay 3.4 ± 1.4 days. Of the laparoscopic cecostomy patients, 56% were male, with mean age 10.5 ± 4 years, mean operative time 100.8 ± 19.1 minutes, and mean length of stay 3.8 ± 1.6 days. There was no statistical difference between the 2 groups. The single intraoperative complication during LAPEC was a cecal hematoma. Postoperative complications after LAPEC included 6 patients with low-grade fever, 3 patients with tube dislodgement (2 treated by repeat LAPEC and the other by open surgery), and 2 patients with skin breakdown. Of the 50 LAPEC patients and their families, 48 were satisfied with the outcome. LIMITATIONS: Retrospective study. CONCLUSION: LAPEC is a safe, minimally invasive procedure for cecostomy placement in children with refractory constipation or fecal incontinence.

Ureteroileocecal appendicostomy based urinary reservoir in irradiated and nonirradiated patients.

PURPOSE: The ureteroileocecal appendicostomy reservoir is designed to potentially decrease the morbidity of continent diversion, particularly in previously irradiated patients. We report our experience with this reservoir to compare complications in irradiated and nonirradiated patients. MATERIALS AND METHODS: The records of 52 consecutive patients who underwent ureteroileocecal appendicostomy diversion between March 2001 and January 2008 were evaluated. Outcomes were analyzed according to whether patients received radiation therapy to the pelvis. Complications were reported as early (within 90 days of surgery) or late. RESULTS: Overall 29 patients received radiation therapy. The incidence of early complications requiring operative intervention was 14%, including 2 patients (9%) with and 5 (17%) without radiation (p = 0.68). All except 1 reoperation was done to revise the stoma. Early urinary tract infections developed in 17% of nonirradiated and 28% of irradiated patients (p = 0.51). The most common late complication was stomal stenosis requiring dilation on an outpatient basis, which occurred in 21% of patients, including 4 with (17%) and 7 without (24%) radiation (p = 0.74). Late ureteral complications requiring intervention were reported in 15% of renal units, including 2 of 44 without (5%) and 6 of 56 with (11%) radiation (p = 0.21). CONCLUSIONS: Ureteroileocecal appendicostomy is a safe, effective technique for continent cutaneous urinary diversion in heavily irradiated patients. Complication rates did not significantly differ between irradiated and nonirradiated patients, and appear improved compared to those in previous reports.
