Stoma complications: the Cook County Hospital experience

Use of visible spectrophotometry to assess tissue oxygenation in the colostomy stoma

The aims of this study were to determine the normal range of tissue oxygenation (SO(2)) in the "mature" colostomy stomacolostomy stoma and to investigate whether there were any diurnal variationsdiurnal variations in the SO(2) values. Ten patients with an end colostomy for a minimum duration of three months and using conventional colostomy bags were included in this study. Tissue SO(2) Tissue SO(2) was measured on the stoma using visible wavelength spectroscopy (Whitland RM 200, Whitland Research, Whitland, UK) The measurements were carried out on each patient on three occasions: the first early in the morning (designated "baseline"), a second after 6 h and the third on the next day at 24 h. The results showed that the mean baseline SO(2) in the colostomy stoma was 77.6 +/- 6.8 and there were no differences in the SO(2) measurements between the baseline, 6 h and the 24 h values. There were also no differences in the SO(2) values between the four quadrants of the stomas. In conclusion, visible wavelength spectrophotometry can reliably measure stomal SO(2) in a non-invasive way. No significant diurnal variations in the stomal SO(2) values were detected.

Does liquid tissue adhesive increase satisfaction with wound and stoma management after surgery?

OBJECTIVE

This pilot study reviews the impact of tissue adhesive to seal skin wounds in elective large bowel resections where a stoma is fashioned.

METHOD

Patients undergoing elective colorectal resection over six-month period were prospectively evaluated for wound infections rates, length of inpatient stay and patient satisfaction with their wound and stoma management. The wounds were observed for 30 days in both inpatient and outpatient settings. A patient satisfaction questionnaire was used with respect to the stoma and wound management.

RESULTS

Fifty patients undergoing elective colorectal resection over a six-month period were prospectively evaluated. The median patient ages were 63.5 years (40-83) for males and 60 years (33-85) for females. Ninety-two per cent of the patients found their wound management satisfactory (overall satisfaction score >5, where 5 represents 'high satisfaction'). Eighty-six per cent reported a stoma management satisfaction score of >4 (where for 4 represents 'satisfaction'). Stoma site leakage was reported by 16%, but none of these developed a SSI. Two patients who had laboratory-confirmed SSI; they had an average length of inpatient stay of 18 days compared with 6.5 days for patients without SSI. .

CONCLUSION

Liquid tissue adhesive provides a flexible, water-resistant and protective coating which increases the satisfaction and ease of surgical wound and stoma management. We recommend a randomised controlled trial be conducted to evaluate these results in larger cohorts.

Self expanding wall stents in malignant colorectal cancer: is complete obstruction a contraindication to stent placement?

OBJECTIVE

Technical failures have previously been associated with complete clinical obstruction and complete block to the retrograde flow of gastrograffin is considered by some to be a contraindication to the procedure. We report on the technical and clinical success rates of self-expanding metallic stents (SEMS) in both complete and incomplete obstruction in a prospective series of malignant colorectal obstructions.

METHOD

A prospective study of all patients undergoing attempted palliative and bridge to surgery SEMS placement for malignant colorectal obstruction over a 7-year period (April 1999-October 2006) was undertaken.

RESULTS

Seventy-two patients (49 males) with a mean age of 71 years (range 49-98) were included. Technical success was achieved in 27 of 32 patients (84%) with complete obstruction and 33 of 36 patients (92%) with incomplete obstruction, P < 0.46, Fishers exact test. Clinical success was achieved in 17 of 26 patients (65%) with complete obstruction and 24 of 33 patients (73%) with incomplete obstruction, P < 0.58, Fishers exact test. Although placed correctly in 89% cases, relief of symptoms occurred in only 71%, P = 0.002, matched pairs test. There were two colonic perforations in the series with one procedure related death.

CONCLUSION

Placement of SEMS for obstructing colorectal cancer is technically successful in a high proportion of cases. Complete radiological obstruction is not a contraindication to stent placement. The relief of obstructive symptoms following successful placement of a wall stent is less predictable.

Can we identify the patients who are likely to undergo bowel resectionat the time of surgery for ovarian cancer?

Surgery for ovarian cancer carries a risk of bowel resection to either achieve optimal debulking or relieve obstruction. This prospective study assessed the likelihood of bowel resection in 842 women undergoing surgery for ovarian cancer and identified factors associated with increased risk. Bowel resection was performed in 8.6% of women. The likelihood of bowel resection increased significantly (p < 0.0001, chi2 test) with: Secondary surgery (22% vs 5.8% at primary surgery). Symptoms of bowel disturbance (21.9% vs 6.3% if no symptoms). FIGO stage III/IV disease (12.8% vs 2% in stage I/II). CA125 levels >or=2500 (12.9% vs 4.8% if CA125<2500). These women should be selectively offered pre-operative computerised tomography, stoma marking and counselling by stoma nurses. The 5-year survival was 14% in patients following bowel resection compared with 44% in patients not having bowel resection. Bowel resection should be performed only if it will result in optimal debulking or it relieves imminent bowel obstruction.

Elective (planned) colectomy in patients with colorectal obstruction after placement of a self-expanding metallic stent as a bridge to surgery: the results of a prospective study

INTRODUCTION

Acute malignant colorectal obstruction (CRO) can be satisfactorily dealt by the placement of a self-expanding metallic stent (SEMS). The aim of this prospective study was to evaluate the rate of elective (planned) colectomy (EPC) in patients with CRO after SEMS placement as a bridge to surgery on an intention-to-treat (ITT) basis.

METHOD

From 2002 to 2007, 30 SEMS were placed as a bridge to surgery in 30 CRO patients (median age 73 +/- 12 years). The obstructing lesions were located in the right (n = 1), transverse (n = 1) or left colon (n = 24) or the upper third of the rectum (n = 4).

RESULTS

The SEMS was placed successfully in 25 (83%) patients. Five patients underwent Hartmann's procedure (n = 2) or a diverting colostomy (n = 3). The SEMS was functionally operational in 23 (92%) of the 25 patients. A diverting colostomy was avoided in 23 (77%) of the 30 patients (placement failure n = 5, clinical failure n = 2). There were no complications in 17 (80%) patients. On an ITT basis, 70% of the patients (21 out of 30) underwent an EPC.

CONCLUSION

On an ITT basis, SEMS placement in CRO patients enabled EPC in 70% of patients.

Bleeding stomal varices: a marker of chronic liver disease

A 44-year-old man presented with acute onset painless haemorrhage from his ileostomy. He had undergone panproctocolectomy for ulcerative colitis 17 years previously. Immediately following admission, he experienced further massive haemorrhage, developing hypovolaemic shock. Active resuscitation including suturing of a bleeding stomal varix was successful. An ultrasound scan of the liver was reported to be normal and the patient was discharged for further outpatient investigation. However he reattended 8 days later with further significant haemorrhage. Investigation with CT revealed portal hypertension and cirrhosis. The patient is currently awaiting a transjugular intrahepatic portosystemic shunt (TIPS) procedure and transjugular biopsy to alleviate his portal hypertension and yield a tissue sample for histological diagnosis. The case highlights the need for clinicians to have a high index of suspicion when presented with bleeding stomas. Further investigation is warranted and may reveal significant underlying hepatic disease. Additionally, further procedures may be necessitated to prevent recurrence of haemorrhage.

Combination endo-radiological colorectal stenting: a prospective 5-year clinical evaluation

OBJECTIVE

Self-expanding metallic stents have found increasing use in the palliation of malignant large-bowel obstruction or as a 'bridge to surgery' to facilitate a planned operative procedure. We describe a 5-year experience of using the combined endoscopic/fluoroscopic through-the-scope method of stent placement in a tertiary referral centre.

METHOD

A prospective database of patients referred for colorectal stenting was compiled. Technical success, clinical success (decompression) and procedure-related complications were measured as end-points.

RESULTS

Sixty-three patients underwent 71 stenting procedures; 39 (62%) patients were male and the median age of patients was 78 years; 32 patients had metastatic disease and seven strictures were due to extrinsic compression. The indication for stenting was palliation in 56 patients and preoperative in seven patients. There was a technical success rate of 91% and a clinical success rate of 89%. Complications occurred in 24% of the cohort: overgrowth, (8%), migration (6%), fistulation (4%), stent fracture (3%), tenesmus (3%) and faecal urgency (1%). There was no procedure-related death within the cohort and no technical failures proximal to the descending colon.

CONCLUSION

Combination endoscopic/fluoroscopic colorectal stenting is effective and safe. It may be particularly useful in the stenting of more proximal colonic strictures.

Ileostomy revision using noncutting linear stapler

OBJECTIVE

The study aimed to evaluate the outcome of ileostomy revision for retraction and prolapse using noncutting linear stapler.

METHOD

Forty five patients undergoing a total of 94 stapled revisions between 1.1.1995 and 31.12.2005 were identified by the unique code for stomal revision. Medical records for all patients were examined.

RESULTS

Thirty-five (77.8%) of the 45 patients were women. In 43 (95.6%), the indication was stomal retraction. Median follow-up was 28 months (2-122). One or more stapling procedures resulted in a normal stoma at follow-up in 18 (41.9%) of 43 patients treated for stomal retraction. When other types of repair were included, a normal stoma was achieved in 30 (69.8%) of 43 patients. Patients with a low BMI had the lowest success rate (44%), but none of the possible factors analysed for influence on success had a statistically significant impact. Two patients were treated for prolapse, and both needed other types of revision.

CONCLUSIONS

Stapled ileostomy revision is easy to perform and has a low morbidity. Less than half the patients achieve a satisfactory long-term result after one or more stapling procedures. Many patients still benefit from other types of revision when stapling has failed.

Expandable metal stent placement for benign colorectal obstruction: outcomes for 23 cases

BACKGROUND

Self-expanding metal stents (SEMS) are an established treatment for palliation of malignant colorectal strictures and as a bridge to surgery for acute malignant colonic obstruction. Patients with benign colonic strictures may benefit from stent placement, but little data exist for this indication.

METHODS

All cases of colonic stent placement identified from a prospectively collected gastrointestinal database from April 1999 to August 2006 were reviewed. During the study period, 23 patients with benign obstructive disease underwent endoscopic SEMS placement. The etiologies of the stricture were diverticular/inflammatory (n = 16), postsurgical anastomotic (n = 3), radiation-induced (n = 3), and Crohn's (n = 1) disease. All strictures were located in the left colon. Five patients had an associated colonic fistula. Uncovered Enteral Wallstents or Ultraflex Precision Colonic stents (Boston Scientific) were endoscopically placed in all but one patient.

RESULTS

Stent placement was technically successful for all 23 patients, and obstruction was relieved for 22 patients (95%). Major complications occurred in 38% of the patients including migration (n = 2), reobstruction (n = 4), and perforation (n = 2). Of these major complications, 87% occurred after 7 days. Four patients did not undergo an operation. Of the 19 patients who underwent planned surgical resection, 16 were successfully decompressed and converted from an emergent operation to an elective one with a median time to surgical resection of 12 days (range, 2 days to 18 months). Surgery was delayed more than 30 days after stent placement for six of these patients. Of the 19 patients who underwent a colectomy, 8 (42%) did not need a stoma after stent insertion.

CONCLUSIONS

SEMS can effectively decompress high-grade, benign colonic obstruction, thereby allowing elective surgery. The use of SEMS can offer medium-term symptom relief for benign colorectal strictures, but this approach is associated with a high rate of delayed complications. Thus, if elective surgery is planned, data from this small study suggest that it should be performed within 7 days of stent placement.

Local correction of extreme stomal prolapse following transverse loop colostomy

BACKGROUND

Stomal prolapse is a common complication of transverse loop colostomies. Although rarely required, surgical correction is associated with potential morbidity. We describe a novel surgical approach to repair stomal herniation that aims to decrease perioperative morbidity.

CASE

A 57 year-old patient with stage IVB adenocarcinoma of the cervix underwent a transverse loop colostomy for palliation of a rectovaginal fistula. Several months later, she presented with a large symptomatic stomal prolapse and elected local surgical correction. Under general anesthesia, we performed a revision of the colostomy with a stapling device.

CONCLUSION

Although long-term data are lacking, this approach is easy, safe, and a reasonable alternative for palliative revision of a prolapsed colostomy stoma.

Early stomal complications

The creation of intestinal stomas for diversion of enteric contents is an important component of the surgical management of several gastroenterologic disease processes. Despite the frequency with which these procedures are performed, complications of stoma creation remain common, despite extensive measures aimed at reducing them. Early postoperative complications (those seen less than one month postoperatively) can lead to significant cost, both financially and psychologically, and incur significant morbidity. Commonly seen early postoperative stomal complications include improper stoma site selection, vascular compromise, retraction, peristomal skin irritation, peristomal infection/abscess/fistula, acute parastomal herniation and bowel obstruction, and pure technical errors. The author reviews these early complications associated with stoma creation, discusses means of preventing them, and outlines the management strategy for such complications when they do occur.

The impact of obesity on outcome after major colorectal surgery

PURPOSE

There is an epidemic of obesity in the Western world and its associated substantial morbidity and mortality. This review examines the data on the impact of obesity on perioperative morbidity and mortality specifically in the context of colorectal surgery.

METHODS

MEDLINE, PUBMED, and the Cochrane library were searched for relevant articles. A manual search for other pertinent papers also was performed.

RESULTS

There is good evidence that obesity is a risk factor for wound infection after colorectal surgery. Obesity may increase the risk of wound dehiscence, incisional site herniation, and stoma complications. Obesity is linked to anastomotic leak, and obese patient undergoing rectal resections may be at particular risk. There is little data on the impact of obesity on pulmonary and cardiovascular complications after colorectal surgery. Operation times are longer for rectal procedures in obese patients, but hospital stay is not prolonged. Obese patients undergoing laparoscopic colorectal surgery are at increased risk of conversion to an open procedure.

CONCLUSIONS

Obesity has a negative impact on outcome after colorectal surgery. To further clarify the impact of obesity on surgical outcome, it is recommended that future studies examine grades of obesity and include measures of abdominal obesity.

Palliation of colorectal cancer

Patients with advanced incurable colorectal cancer (CRC) face a grim prognosis. The goal of palliative intervention is directed at alleviating disease-related symptoms and improving quality of life. The provision of optimal palliative care for these patients is a compound and demanding process. This dilemma becomes more challenging when patients with advanced metastatic colorectal disease present with an incurable and asymptomatic primary lesion. Treatment options are numerous and include a variety of surgical and nonsurgical interventions. Most data regarding the role of surgery in palliation of CRC are from retrospective, nonrandomized case series. Surgical resection may provide good palliation of symptoms and prevent future tumor-related complications. Metal stents are also able to provide good palliative relief of obstruction and should be used when appropriate. The best palliative care will often require a multidisciplinary approach that involves input from surgical and nonsurgical teams, where treatment plans will be made in accordance with the wishes of the patient and family with a goal of decreasing morbidity and a focus on quality of life.

Use of colonic stents in emergent malignant left colonic obstruction: a Markov chain Monte Carlo decision analysis

PURPOSE

This decision analysis examines the cost-effectiveness of colonic stenting as a bridge to surgery vs. surgery alone in the management of emergent, malignant left colonic obstruction.

METHODS

We used a Markov chain Monte Carlo decision analysis model to determine the effect on health-related quality of life of two strategies: emergency surgery vs. emergency colonic stenting as a bridge to definitive surgery. All relevant health states were modeled during a patient's expected lifespan. Outcome measures were mortality, the proportion of patients requiring a colostomy, quality-adjusted life expectancy, and costs. Deterministic and probabilistic sensitivity analyses were performed.

RESULTS

In our model, colonic stenting was more effective (9.2 quality-adjusted life months benefit) and less costly (CAD dollars 3,763; US dollars 3,135) than emergency surgery. Its benefits were secondary to reductions in acute mortality and in the likelihood of requiring a permanent colostomy. The results were only dependent on the rate of stenting complications (perforation, technical placement failure, and migration) and the patient's risk of surgical mortality, with the benefits being greatest among patients at high risk of operative mortality.

CONCLUSIONS

Colonic stenting as a bridge to surgery is more effective and less costly than surgery in the treatment of emergent, malignant left colonic obstruction. The benefits are most pronounced in high-risk patients and are diminished by increases in stent placement failure rates and perforation rates. In low-risk patients, the benefits are more modest and may not outweigh the risks.

Results of a nationwide prospective audit of stoma complications within 3 weeks of surgery

OBJECTIVE

Actuarial analysis of stoma complications (problematic stomas) is lacking. The objectives of this audit were: to identify the incidence of stoma complications within the UK; to highlight any dissimilarity of incidence from centre to centre; to ascertain if the height of the stoma (distance of stoma lumen from the skin) at the time of fashioning is a predisposing factor to problems; and finally to initiate much needed research.

METHOD

Commencing 1st January 2005, stoma care services nationwide (256) were invited to audit prospectively their next 50 enteric stomas or for a period of 1 year which ever came first. The definition of a problematic stoma being one, which needed one or more accessories to keep the patient clean and dry for a minimum period of 24 h. The incident is to have happened within 3 weeks of surgery. Factors taken into account were: type of stoma, height of stoma within 48 h of surgery; emergency or elective procedure, problem identified, BMI, gender and underlying diagnosis of the patient. The identities of the participating centres are confidential.

RESULTS

Of the 256 hospital-based stoma care services within the UK, 93 (36%) participated. A total of 3970 stomas were recorded, of which 1329 (34%) were identified as problematic. Sixty-two centres reported 45-50 stomas with a range of complications 6-96%. The loop ileostomy was found to be the stoma which causes most problems. A stoma of <10 mm is a predisposing factor to complications and problems are more likely to occur following an emergency procedure. More men than women have stomas formed, but have significantly fewer problems and there is no significant difference between underlying diagnoses.

CONCLUSION

The stoma height, stoma type and gender of the patient are significant risk factors identified in this audit. The BMI of patient did not affect the outcome. Patients undergoing an emergency procedure are more likely to have a problematic stoma. The significant variation of complications from centre to centre indicates surgical technique as being the key factor in stoma formation and subsequent quality of life for the patient.

Colorectal stenting: an effective therapy for preoperative and palliative treatment

PURPOSE

To demonstrate the effectiveness of preoperative and palliative colorectal stent placement in acute colonic obstruction.

METHODS

Sixty-seven consecutive patients (mean age 67.3 years, range 25-93 years) with clinical and radiological signs of colonic obstruction were treated: 45 (67%) preoperatively and 22 (33%) with a palliative intent. In 59 patients (88%) the obstruction was malignant, while in 8 (12%) it was benign. A total of 73 enteric Wallstents were implanted under combined fluoroscopic/endoscopic guidance.

RESULTS

Forty-five patients were treated preoperatively with a technical success rate of 84%, a clinical success rate of 83%, and a complication rate of 16%. Of the 38 patients who were successfully stented preoperatively, 36 (95%) underwent surgery 2-22 days (mean 7.2 days) after stent insertion. The improved general condition and adequate bowel cleansing allowed single-stage tumor resection and primary end-to-end anastomosis without complications in 31 cases (86% of all operations), while only 5 patients had colostomies. Stent placement was used as the final palliative treatment in 22 patients. The technical success rate was 95%, the clinical success rate 72%, and the complication rate relatively high at 67%, caused by reocclusion in most cases. After noninvasive secondary interventions (e.g., tube placement, second stenting, balloon dilatation) the secondary patency of stents was 71% and mean reported survival time after stent insertion was 92 days (range 10-285 days).

CONCLUSION

Preoperative stent placement in acute colonic obstruction is minimally invasive and allows an elective one-stage surgery in most cases. Stent placement also proved a valuable alternative to avoid colostomy in palliation.

Paraileostomy recontouring by collagen sealant injection: a novel approach to one aspect of ileostomy morbidity. Report of a case

INTRODUCTION

Poorly fitting stoma appliances, resulting in stomal leakage and subsequent skin excoriation, remain a significant cause of ileostomy-related morbidity. One cause of ill-fitting stoma bags is the presence of parastomal dermal contour defects/irregularities. These may occur after surgical complications or change in patient weight and body habitus.

METHODS

We report the case of a 29-year-old man who, after panproctocolectomy and formation of ileostomy for ulcerative colitis, experienced significant problems with stoma bag application because of dermal contour defects. As a result, he suffered from significant stomal leakage and skin excoriation. After a single treatment of cutaneous parastomal infiltration of porcine collagen (Permacol Injection), applied stoma bags achieved a watertight seal, and the patient experienced complete and sustained resolution of his symptoms.

CONCLUSIONS

Porcine collagen is a safe, versatile, and relatively easy method of restoring irregular skin defects surrounding abdominal stomas, thus resolving the significant patient morbidity associated with ill-fitting stomal appliances. Such a technique avoids the need for surgical stoma refashioning, which may be associated with significant morbidity and unsatisfactory outcomes.

Preoperative colonic stenting: how, when and why?

PURPOSE OF REVIEW

Acute colonic obstruction due to malignancy is often a surgical emergency. Surgical decompression with colostomy with or without resection and eventual re-anastomosis has traditionally been the treatment of choice. These procedures have been associated with a significant morbidity and mortality rate. Preoperative colonic stenting is effective for decompressing the obstructed colon and may allow for surgery to be performed on an elective basis.

RECENT FINDINGS

Although randomized clinical data are lacking, the role for preoperative stenting in the emergent management of acute malignant colonic obstruction has been supported by cost-effectiveness analysis studies and several pooled analyses that demonstrate efficacy and safety.

SUMMARY

This review evaluates the latest developments in colonic stent technology, indications for use in the preoperative setting, and evidence to support their use in this setting.

Colonic stenting as bridge to surgery versus emergency surgery for management of acute left-sided malignant colonic obstruction: a multicenter randomized trial (Stent-in 2 study)

Background

Acute left-sided colonic obstruction is most often caused by malignancy and the surgical treatment is associated with a high mortality and morbidity rate. Moreover, these operated patients end up with a temporary or permanent stoma. Initial insertion of an enteral stent to decompress the obstructed colon, allowing for surgery to be performed electively, is gaining popularity. In uncontrolled studies stent placement before elective surgery has been suggested to decrease mortality, morbidity and number of colostomies. However stent perforation can lead to peritoneal tumor spill, changing a potentially curable disease in an incurable one. Therefore it is of paramount importance to compare the outcomes of colonic stenting followed by elective surgery with emergency surgery for the management of acute left-sided malignant colonic obstruction in a randomized multicenter fashion.

Methods/design

Patients with acute left-sided malignant colonic obstruction eligible for this study will be randomized to either emergency surgery (current standard treatment) or colonic stenting as bridge to elective surgery. Outcome measurements are effectiveness and costs of both strategies. Effectiveness will be evaluated in terms of quality of life, morbidity and mortality. Quality of life will be measured with standardized questionnaires (EORTC QLQ-C30, EORTC QLQ-CR38, EQ-5D and EQ-VAS). Morbidity is defined as every event leading to hospital admission or prolonging hospital stay. Mortality will be analyzed as total mortality as well as procedure-related mortality. The total costs of treatment will be evaluated by counting volumes and calculating unit prices. Including 120 patients on a 1:1 basis will have 80% power to detect an effect size of 0.5 on the EORTC QLQ-C30 global health scale, using a two group t-test with a 0.05 two-sided significance level. Differences in quality of life and morbidity will be analyzed using mixed-models repeated measures analysis of variance. Mortality will be compared using Kaplan-Meier curves and log-rank statistics.

Discussion

The Stent-in 2 study is a randomized controlled multicenter trial that will provide evidence whether or not colonic stenting as bridge to surgery is to be performed in patients with acute left-sided colonic obstruction.

A meta-analysis of quality of life for abdominoperineal excision of rectum versus anterior resection for rectal cancer

BACKGROUND

Avoiding a permanent stoma following rectal cancer excision is believed to improve quality of life (QoL), but evidence from comparative studies is contradictory. The aim of this study was to compare QoL following abdominoperineal excision of rectum (APER) with that after anterior resection (AR) in patients with rectal cancer.

METHODS

A literature search was performed to identify studies published between 1966 and 2006 comparing values of QoL following APER and AR. Random-effect meta-analysis was used to combine the data. Sensitivity analyses were performed for larger studies, those of higher quality and those using self-administered QoL questionnaires.

RESULTS

The outcomes for 1,443 patients from 11 studies, of whom 486 (33%) underwent APER, were included. QoL assessments were made at periods of up to 2 years following surgery. There was no significant difference in global health scores between APER and AR. Vitality (WMD -9.82; 95% CI -27.01, -2.04, P = 0.01) and sexual function (WMD -2.73; 95% CI -4.93, -0.64, P = 0.01) were improved in the AR patients. Patients with low AR had improved physical function scores in comparison with APER patients (WMD -4.67; 95% CI -9.10, -0.23; P = 0.004). Cognitive (WMD 3.57; 95% CI 1.41, 5.73; P < 0.001) and emotional function scores (WMD 3.51; 95% CI 1.40, 5.62; P < 0.001) were higher for APER patients.

CONCLUSION

Overall, when comparing APER with AR, we identified no differences in general QoL following the procedures. Individualisation of care for rectal cancer patients is essential, but a policy of avoidance of APER cannot currently be justified on the grounds of QoL alone.

The cost-effectiveness of colonic stenting as a bridge to curative surgery in patients with acute left-sided malignant colonic obstruction: a Canadian perspective

BACKGROUND

Over the past several years, colonic stenting has been advocated as an alternative to the traditional surgical approach for relieving acute malignant left-sided colonic obstruction. The aim of the present study was to determine the most cost-effective strategy in a Canadian setting. patients and

METHODS

A decision analytical model was developed to compare three competing strategies: CS - emergent colonic stenting followed by elective resective surgery and reanastomosis; RS - emergent resective surgery followed by creation of either a diverting colostomy or primary reanastomosis; and DC - emergent diverting colostomy followed by elective resective surgery and reanastomosis. The costs were estimated from the perspective of the Manitoba provincial health plan.

RESULTS

The use of CS resulted in fewer total operative procedures per patient (mean CS 1.03, RS 1.32, DC 1.9), lower mortality rate (CS 5%, RS 11%, DC 13%) and lower likelihood of requiring a permanent stoma (CS 7%, RS 14%, DC 14%). CS is slightly more expensive than DC, but less costly than RS (DC 11,851 dollars, CS 13,164 dollars, RS 13,820 dollars). The incremental cost-effectiveness ratio associated with the use of CS versus DC is 1,415 dollars to prevent a temporary stoma, 1,516 dollars to prevent an additional operation and 15,734 dollars to prevent an additional death.

CONCLUSIONS

Colonic stenting for patients with acute colonic obstruction secondary to a resectable colonic tumour is comparable in cost with surgical options, and reduces the likelihood of requiring both temporary and permanent stomas. Colonic stenting should be offered as the initial therapeutic modality for Canadian colorectal cancer patients presenting with acute obstruction as a bridge to definitive RS.

Difficulties Experienced by the Ostomate After Hospital Discharge

PURPOSE

This descriptive study used a mailed survey to identify difficulties related to the stoma that ostomates experience after discharge from the hospital, who they sought help from, and if the advice was perceived as helpful.

SUBJECTS AND SETTING

Ostomates who are 18 years or older and have undergone a urinary or fecal diversion at a North Carolina hospital between January 1, 2003 and June 30, 2005, were asked to respond to a survey about the difficulties related to their ostomy.

INSTRUMENT

The survey gathered demographic and anthropometric data, information regarding stomal complications, self-evaluation of emotional state, and contact with clinicians and support groups.

RESULTS

Of the 140 surveys mailed, 43 were returned, demonstrating a return rate of 31%. Thirty-four returned surveys were useable for statistical analysis. The top 5 difficulties experienced by the respondents were peristomal skin irritation (76%), pouch leakage (62%), odor (59%), reduction in previously enjoyed activities (54%), and depression/anxiety (53%). Twenty percent of the ostomates who experienced difficulties after surgery did not seek help. Ostomates primarily sought help from nurses when they experienced problems related to the stoma and its maintenance. For mental health, sleep, and sexual problems, a medical doctor was the practitioner of choice. Ostomates were satisfied with most of the help they received from an ostomy nurse; satisfaction was lower for home health nurses and surgeon or primary care physician practices. Average wear time for a stoma pouch was 4 days.

CONCLUSION

The majority of the ostomates experienced difficulty with pouch leakage, skin irritation, odor, depression or anxiety, and uneven pouching surfaces. Ostomates desire assistance with these problems and will benefit from long-term follow-up by an ostomy nurse.

Comparison of colonic stenting and open surgery for malignant large bowel obstruction

BACKGROUND

Colonic stents potentially offer effective palliation for those with bowel obstruction attributable to incurable malignancy, and a "bridge to surgery" for those in whom emergency surgery would necessitate a stoma. The current study compared the outcomes of stents and open surgery in the management of malignant large bowel obstruction.

METHODS

A literature search of the Medline, Ovid, Embase and Cochrane databases was performed to identify comparative studies reporting outcomes on colonic stenting and surgery for large bowel obstruction. Random effects meta-analytical techniques were applied to identify differences in outcomes between the two groups. Sensitivity analysis of high quality studies, those reporting on more than 35 patients, those solely concerning colorectal cancer and studies performing intention to treat analysis was undertaken to evaluate the study heterogeneity.

RESULTS

A total of 10 studies satisfied the criteria for inclusion, with outcomes reported for 451 patients. Stent insertion was attempted for 244 patients (54.1%), and proved successful for 226 (92.6%). The length of hospital stay was shorter by 7.72 days in the stent group (p < 0.001), which also had lower mortality (p = 0.03) and fewer medical complications (p < 0.001). Stoma formation at any point during management was significantly lower than in the stent group (odds ratio, 0.02; p < 0.001), and "bridging to surgery" did not adversely influence survival.

CONCLUSIONS

Colonic stenting offers effective palliation for malignant bowel obstruction, with short lengths of hospital stay and a low rate for stoma formation, but data on quality of life and economic evaluation are limited. There is no evidence of differences in long-term survival between those who have stents followed by subsequent resection and those undergoing emergency bowel resection.

One-stage laparoscopic colorectal resection after placement of self-expanding metallic stents for colorectal obstruction: a prospective study

The aim of this study was to assess the clinical outcomes of self-expandable metallic stents placing followed by laparoscopic resection and primary anastomosis for the treatment of acute colonic obstruction. From January 2003 to December 2004, 14 patients diagnosed with acute and complete colonic obstruction were treated with endoscopic colonic stenting as a bridge to an elective 1-stage laparoscopic resection. Three patients who underwent a successful stent insertion but had an inoperable tumor were excluded from the analyzed data. Ninety-three percent technical and clinical success was achieved. The stent insertion related perforation rate was 7% (1/14). The mean duration of stent insertion was approximately 1 hour and the mean time between the stent insertion and surgery was 6.2 days. Mean operating time was 132 +/- 38 minutes. No cases required conversion to laparotomy and there were no intraoperative complications. One case of anastomotic leakage was observed and treated by laparoscopic drainage and protective ileostomy. Ambulation time after operation was 1.8 +/- 0.6 days and total hospital stay length was 16.4 +/- 5.0 days. During a period of 11 +/- 7 months of follow-up, neither recurrences nor port-site metastases were observed. The management of acute colonic obstruction using endoscopic stent decompression, followed by laparoscopic resection, had good results and can be considered feasible and safe. Larger comparative studies may help to establish this approach.

Use of W-plasty in stenotic stoma: a new solution for an old problem

INDICATION

Amongst late complications of stomas, stenosis can be difficult to treat. Repeated dilatations rarely achieve long-term resolution and re-fashioning is not always successful. Application of an existing plastic surgical technique to treat stomal stenosis is described.

METHOD

After marking the skin, a W-plasty is made with a number of consecutive small triangular flaps through the skin. The corresponding mucosal margin is then made to interdigitate with this configuration and fixed using a Gillies corner stich with 5/0 Vycril rapide on a compound curved needle.

RESULTS

Five patients underwent W-plasty reconstruction for a stenotic stoma. Median follow up was 12.5 months (range 11-15). No patient had stenosis of the stoma on review and the patient satisfaction rate was high.

CONCLUSION

The W-plasty technique is a new treatment for stenotic stoma.

Colon and rectal injuries

PURPOSE

This study was designed to develop treatment algorithms for colon, rectal, and anal injuries based on the review of relevant literature.

METHODS

Information was obtained through a MEDLINE ( www.nobi.nih.gov/entrez/query.fcgi ) search, and additional references were obtained through cross-referencing key articles cited in these papers.

RESULTS

A total of 203 articles were considered relevant.

CONCLUSIONS

The management of penetrating and blunt colon, rectal, and anal injuries has evolved during the past 150 years. Since the World War II mandate to divert penetrating colon injuries, primary repair or resection and anastomosis have found an increasing role in patients with nondestructive injuries. A critical review of recent literature better defines the role of primary repair and fecal diversion for these injuries and allows for better algorithms for the management of these injuries.

Morbidity of temporary loop ileostomy in patients with colorectal cancer

PURPOSE

This study was designed to quantify the temporary loop ileostomy-related morbidity in patients with colorectal cancer and contrast the morbidity rates after ileostomy closure before, during, and after the start of adjuvant therapy.

METHODS

Between 1997 and 2004, 120 patients with colorectal carcinoma underwent colorectal resection and creation of a temporary loop ileostomy to protect the low anastomosis. Stoma-related complications and perioperative morbidity after ileostomy closure were assessed retrospectively by reviewing the medical records.

RESULTS

Sixteen of the 120 patients (13.3 percent) suffered stoma-related complications, requiring early ileostomy closure in three. After ileostomy closure, anastomotic leakage of the ileoileostomy occurred in 3 of the 120 patients (2.5 percent), 2 of them died postoperatively (1.7 percent). The rate of minor complications (16.7 percent in all patients) was much higher in patients undergoing adjuvant chemotherapy or radiochemotherapy (25.5 percent) than in patients receiving no additional therapy (9.2 percent). In the former patients, there was a trend toward fewer complications when ileostomy closure was performed before (12.5 percent), rather than during (42.9 percent) or after (21.2 percent), the start of adjuvant therapy.

CONCLUSIONS

The morbidity following closure of a temporary loop ileostomy in colorectal cancer patients is much higher in patients receiving adjuvant chemotherapy or radiochemotherapy. The morbidity, however, might possibly be lowered to the level of patients receiving no additional therapy if ileostomy closure is performed before the start of adjuvant therapy.

Colorectal stenting for colonic obstruction: the indications, complications, effectiveness and outcome--5 year review

INTRODUCTION

Currently self-expanding metallic stents are being used for palliation and acute decompression of colonic obstruction. The aim of this study is to review our experience of using these metallic stents over a 5-year period.

MATERIALS AND METHODS

Case records of 102 patients who had colorectal stenting between 1998 and 2004 were reviewed retrospectively. The indications for colorectal stenting, efficacy of the procedure in relieving the obstruction, complications and clinical outcome were analysed.

RESULTS

Ninety-nine patients had malignant disease and in three patients a benign cause of obstruction was demonstrated. All procedures were performed during normal working hours. Stenting was technically successful in 87 patients (85%). A single stent was placed in 80 patients. Seven patients required two stents. Of the successful cases, 67 had stents placed by fluoroscopy alone and 20 by a combined fluoroscopy/endoscopy procedure. Four percent had early complications (within 30 days) which included four perforations. There were late complications (over 30 days) in 9% which included five stent migrations, two blocked stents and one colovesical fistula. Ninety percent (n=76) of the successful patients needed no further radiological or surgical intervention later. Survival ranged from 14 days to 2 years.

CONCLUSION

Colorectal stenting when technically successful is an effective procedure for both preoperative and palliative decompression of colonic obstruction.

Metal stent placement in acute malignant colorectal obstruction

BACKGROUND

Obstruction is a common complication of advanced colorectal cancer. Stent insertion can reduce the need for emergency surgery and allows chemotherapy to begin immediately.

AIMS

To evaluate the technical and clinical success and long-term outcome of stent placement in the management of acute malignant colorectal obstruction.

METHODS

From July 2002 to April 2005, 29 self-expanding metal stents were placed in 24 patients (13 men, mean age 67 years, range 36-83). Stents were inserted under endoscopic and fluoroscopic control. Patients were clinically and endoscopically followed up.

RESULTS

Twenty-eight out of 29 stents were successfully placed (96.5%) in 23 out of 24 patients with 25 strictures. The clinical success rate was 95.8% (23/24). Two early stent migrations were observed in two patients (8.3%). Late complications developed in eight patients (33.3%) after a median of 3.8 months (range <1-8.6): two migrations and six occlusions. The median survival was 9.8 months (range <1-27). Eleven patients (45.8%) died from progressive disease without any clinical evidence of recurrent obstruction.

CONCLUSION

Stent placement is safe and effective. Stent complications are frequent but not life-threatening, and are easy to manage. An improvement in stent design and well-scheduled follow-up are needed in order to prevent such complications.

Descriptive study of peristomal complications

OBJECTIVE

The objective of this study was to assess new ostomy patients for the presence of peristomal complications when they returned for their 2-month postoperative follow-up at a major university hospital.

DESIGN

A prospective descriptive design was used.

SETTING AND SUBJECTS

For 1 year, new ostomy patients were seen at a 540-bed university-based hospital. Subjects included 220 patients with ostomies who underwent a fecal or urinary diversion at a university-based hospital.

INSTRUMENTS AND METHODS

For 12 months, each patient who returned for a 2-month follow-up visit was assessed by 1 of 3 WOC nurses for the presence or absence of peristomal complications using a tool developed by the investigators. The study was conducted from August 2001 to August 2002. Descriptive statistics were used to summarize the data.

RESULTS

A total of 220 new ostomy patients were examined, 35 of whom had peristomal complications for a frequency of 16%. Sixteen of the 35 patients had ileostomies, 10 patients had colostomies, and 9 patients had ileal conduits. Of the 35 patients with peristomal complications, 24 had irritant dermatitis, 7 had mechanical injury, and 3 had Candida infections. The WOC nurses determined the causes of the peristomal complications to be related to flush stomas, peristomal hernias, inappropriate opening in the skin barrier, and mechanical injury from the pouching systems. Nine of 35 patients had flush stomas; 5 patients developed peristomal hernias. For 7 patients, the skin barrier in the pouching system was larger than the stoma, allowing the effluent to contact the peristomal skin, resulting in denuded peristomal skin; and 7 patients had pressure areas on the peristomal skin and were wearing convex pouching systems.

CONCLUSIONS

With more laparoscopic ostomy surgeries resulting in decreased hospital stays, there is less opportunity for the patient to learn pouching techniques and problem solving regarding peristomal complications. Patients require more education regarding peristomal issues and follow-up after discharge to ensure the maintenance of a secure pouching system. Decreased hospital stays and decreased reimbursement for outpatient and home health services will continue to be a challenge for the WOC nurse. There is also a need for universal definitions of complications and the need for continued studies examining the frequency of these complications, as well as the role of stoma site marking in reducing these complications.

Evaluation of the end colostomy complications and the risk factors influencing them in Iranian patients

INTRODUCTION

The aim of this study was to assess the prevalence of end colostomy complications and the evaluation of factors influencing outcome.

PATIENTS AND METHODS

Three hundred and thirty patients with end colostomy were studied. All patient were recalled for examination for recent complications. Early complications included stoma site pain, early dermal irritation (during the first month after surgery), mucosal bleeding, stomal prolapse and psychosocial complications. Late complications included peristomal hernia, stomal stenosis, late dermal irritation (after the first month), stomal retraction, stomal necrosis and other stoma complications (perforation, fistula etc.). Probable underlying factors were studied. To evaluate risk factors affecting complications, univariable analysis and then multivariable analysis by binary logistic regression was performed.

RESULTS

One hundred and one (30.6%) patients had no complications and the remainder had at least one of early or late complications. Overall, psychosocial complications, 56.4%; mucosal bleeding, 34.5%; early dermal irritation, 23.5% were the most frequent complications. Peristomal hernia (11.2%) was the most common late complication. Those aged > 40 years had significant associations with psychosocial problem (OR = 2.77), mucosal haemorrhage (OR = 2.19), and early dermal irritation (OR = 3.14). The risks of peristomal hernia and early dermal irritation are greater in the patients with BMI > 25 kg/m2 (OR = 2.08 and 2.55, respectively).

CONCLUSION

The risk of most prevalent complications of colostomy construction increases in elder patients. The high prevalence of psychosocial and skin problems in patients with a colostomy, needs special attention especially from the viewpoint of education by trained stoma nurses and preparation of standard equipment.

Skin changes induced by a zinc oxide dressing compared with a hydrocolloid dressing in healthy individuals

BACKGROUND/PURPOSE

Incidence of skin complications in ostomy patients constitutes a well-known and well-described problem. The reasons are, however, very difficult to describe because of the many factors contributing to the problem. This article describes the skin changes derived exclusively from the adhesives used in a carefully controlled, long-term study using two fundamentally different types of adhesives: a hydrocolloid adhesive and a zinc oxide adhesive.

METHODS

The adhesives were changed daily on the volar forearm of 11 volunteers for a 4-week period. Once a week, transepidermal water-loss (TEWL), water content of the skin, erythema and the peel force applied for removal of the adhesives were measured. On the last day of the study, a replica of the skin surface was obtained to determine changes in the skin topography, and a biopsy was taken to study changes at the cellular level.

RESULTS AND CONCLUSION

We found increased TEWL and decreased water content in skin treated with the zinc oxide adhesive, but increased water-loss and water content when the hydrocolloid adhesive was used. In addition, the area treated with zinc oxide adhesive showed significant increase of epidermal thickness, scaly appearance and parakeratosis with similarities to pathological dry skin diseases such as psoriasis and atopic dermatitis, changes that were not found when using the hydrocolloid adhesive. The skin response seems to be the result of the content of zinc oxide and the mechanical interaction of the zinc oxide adhesive. We conclude that the nature of the adhesive plays an important role in the skin response to repeated application of adhesives, as seen in peristomal skin.

Hartmann's colectomy and reversal in diverticulitis: a population-level assessment

PURPOSE

This study was designed to assess the costs and outcomes of colostomy and colostomy reversal in patients with diverticulitis and examine the impact of such procedures on the health care system.

METHODS

We employed a retrospective design and used a Washington State administrative database to identify patients undergoing operations with colostomy (1987-2002) who were followed over time. Descriptive and comparative analysis was performed, focusing on patients with diverticulitis.

RESULTS

There were 16,556 patients who underwent colostomy and 5,420 (32.7 percent) were for diverticulitis and its related complications (mean age, 64.8 +/- 15.1 years; 53.2 percent female). In patients with diverticulitis, the rate of colostomy reversal was 56.3 percent (80 percent in patients less than 50 years, and 30 percent in patients over 77 years). The in-hospital mortality rate after colostomy reversal was 0.36 percent, and was 2.6 percent in those over 77 years of age. After colostomy reversal a second stoma was used in 3.4 percent, reoperation was required for bleeding complications in 0.6 percent, and infectious complications were noted in 2 percent. The length of time from colostomy to its reversal was approximately five months (138.1 +/- 164 days; interquartile range, 72-156). The relationship between the length of time from colostomy to reversal was evaluated and the adjusted odds of a second stoma being used at the time of colostomy reversal were 45 percent higher (odds ratio, 1.45; 95 percent confidence interval, 1.22, 1.73) for each increase in time interval (<3, 6-9, 9-12, >12 months).

CONCLUSIONS

One-third of all colostomies were related to diverticulitis and only 56 percent were reversed. We identified a higher than expected mortality rate among older patients undergoing colostomy reversal. The impact of colostomy and reversal operations on both patients and the health care system is significant.

Eight years experience of high-powered endoscopic diode laser therapy for palliation of colorectal carcinoma

PURPOSE

Endoscopic laser therapy using neodymium: yttrium-aluminum-garnet (Nd:YAG) laser has been shown to be effective in palliating symptoms of obstruction, bleeding, and discharge in patients with colorectal cancer. These patients usually have advanced inoperable disease at presentation or are unfit for surgery. We have used high-powered diode laser to palliate patients with inoperable colorectal cancer since 1994. This study was designed to determine the success rate of high-powered diode laser in palliating inoperable colorectal carcinoma and compare these figures with those published for Nd:YAG laser.

METHODS

A retrospective analysis was performed of all patients undergoing high-powered diode laser therapy for colorectal carcinoma between June 1994 and October 2002 (inclusive) at St. George's Hospital, London, United Kingdom. Patient's notes and endoscopy records were reviewed to determine the indications for treatment, success of symptom palliation, complications, and survival for each patient.

RESULTS

Fifty-seven patients (28 males), with a median age at first treatment of 82 (range, 51-93) years, were identified who had been palliated with high-powered diode laser therapy for colorectal carcinoma. The median number of treatments received by each patient was three (range, 1-16 treatments), with a median interval between treatments of 9.5 (range, 1-25) weeks. Lifelong palliation of symptoms occurred in 51 patients (89 percent). Major complications were two perforations and one hemorrhage, giving an overall complication rate of 5.3 percent. One of the patients who experienced perforation died, giving an overall mortality rate of 1.8 percent for the procedure. The median survival of the 51 patients palliated completely by laser therapy was 8.5 (range, 0.6-52) months, with a probability of survival at 24 months of 15 percent.

CONCLUSIONS

High-powered diode laser therapy is an effective method of providing palliation for obstruction, bleeding, and discharge in those patients with inoperable colorectal carcinoma. It produces results comparable to therapy with Nd:YAG laser and the equipment is cheaper, more compact, and portable.

Temporary ileostomy versus temporary colostomy: a meta-analysis of complications

OBJECTIVE

To compare the complications of temporary diverting ileostomy with those of temporary colostomy for patients with colorectal diseases.

METHODS

Two independent researchers conducted a systematic search for randomized controlled trials (RCTs) comparing temporary ileostomy with temporary colostomy in MEDLINE, the Cochrane database, evidence-based medicine reviews and the American College of Physicians journal club, as well as relevant reference lists in journal articles. Five RCTs were found and included in this meta-analysis. All complications were abstracted and compared between groups. All complications were also assessed using tests of statistical heterogeneity, pooling of risk ratios using Mantel-Haenszel fixed effects and DerSimonian and Laird random effects. Clinical heterogeneity was investigated by examining the methodology and selection of patients described in each trial.

RESULTS

Temporary colostomy was significantly more likely to cause stoma complications in colorectal cancer patients undergoing elective resections, and also more likely to cause infectious and wound complications. Temporary ileostomy tended to cause more post-closure surgical complications.

CONCLUSIONS

There is not yet a strong case for the superiority of one temporary diverting stoma over another for all colorectal patients. In this regard, a large, well-conducted RCT is still needed.

Colonic stent vs. emergency surgery for management of acute left-sided malignant colonic obstruction: a decision analysis

BACKGROUND

Acute colonic obstruction because of malignancy is often a surgical emergency. Surgical decompression with colostomy with or without resection and eventual re-anastomosis is the traditional treatment of choice. Endoscopic colonic stent insertion effectively decompresses the obstructed colon, allowing for surgery to be performed electively. This study sought to determine the cost-effectiveness of colonic stent vs. surgery for emergent management of acute malignant colonic obstruction.

METHODS

Decision analysis was used to calculate the cost-effectiveness of two competing strategies in a hypothetical patient presenting with acute, complete, malignant colonic obstruction: (1) emergent colonic stent followed by elective surgical resection and re-anastomosis; (2) emergent surgical resection followed by diversion (Hartmann's procedure) or primary anastomosis. Cost estimates were obtained from a third-party payer perspective. Primary outcome measures were mortality, stoma requirement, and total number of operative procedures.

RESULTS

Colonic stent resulted in 23% fewer operative procedures per patient (1.01 vs. 1.32 operations per patient), an 83% reduction in stoma requirement (7% vs. 43%), and lower procedure-related mortality (5% vs. 11%). Colonic stent was associated with a lower mean cost per patient ($45,709 vs. $49,941).

CONCLUSIONS

Colonic stent insertion followed by elective surgery appears more effective and less costly than emergency surgery under base-case conditions. This finding remains robust over a wide range of assumptions for clinical inputs in sensitivity analysis. Our findings suggest that colonic stent insertion should be offered, whenever feasible, as a bridge to elective surgery in patients presenting with malignant colonic obstruction.

STOMAL COMPLICATIONS OF ILEAL CONDUITS ARE SIGNIFICANTLY HIGHER WHEN FORMED IN WOMEN WITH INTRACTABLE URINARY INCONTINENCE

PURPOSE

The ileal conduit is held to be the safest and simplest form of urinary diversion. There are few reports about long-term problems after ileal conduit formation, especially intractable urinary incontinence in females. We reviewed long-term stomal complications in patients with an ileal conduit.

MATERIALS AND METHODS

Notes on 93 consecutive patients in whom an ileal conduit was created were reviewed. Information was collected on patient demographics, indications for an ileal conduit and long-term complications, in particular parastomal and incisional hernias, stomal retraction, stenosis or prolapse and the development of a redundant loop. Mean followup available was 63.4 months (range 1 to 434).

RESULTS

A total of 33 males with a mean age of 60.1 years (range 2 to 78) and 60 females with a mean age of 48.2 years (range 4 to 79) underwent ileal conduit diversion. The main indications for an ileal conduit were intractable incontinence in 44 patients (47%), cancer in 31 (33%) and interstitial cystitis in 8 (9%). In male, continent female and incontinent female patients A parastomal hernia developed in 3 (9%), 2 (9.5%) and 12 (31%), an incisional hernia developed in 1 (3%), 1 (4.8%) and 2 (5%), stomal retraction developed in 0, 2 (9.5%) and 12 (31%), stomal stenosis developed in 0 (0%), 1 (4.8%) and 6 (15.4%), and a redundant loop developed in 0 (0%), 2 (9.5%) and 5 (12.8%), respectively. A total of 23 patients (24.7%) required further surgery for stomal problems with 13 (57%) requiring more than 1 reoperation, of whom 9 were incontinent females.

CONCLUSIONS

An ileal conduit is associated with a stomal complication rate of 34.4% (61% in incontinent females and 18% in other patients) and a 4.3% incisional hernia rate. Reoperation is required for stomal complications in 24.7% of cases. Stomal complication rates and reoperation rates vary by sex and the indication for ileal conduit, and they are significantly higher for those performed for intractable urinary incontinence in females.
