Management and results of complications after anterior resection with colonic pouch reconstruction for rectal cancer

Aim Colonic J‐pouch reconstruction is widely carried out during low anterior resection. The aim of this observational study was to describe the complications and evaluate the results of adverse event management. Method A total of 128 patients underwent an elective anterior resection with colorectal or coloanal J‐pouch reconstruction for primary rectal cancer between January 1997 and December 2008. Results The overall mortality was 1.6%. Three (2.3%) patients developed pouch necrosis, one of whom died. The rate of anastomotic leakage was 11.7%. Other major complications included intra‐abdominal abscess (3.1%), haemorrhage (0.8%) and abdominal dihiscence (0.8%). In all cases of anastomotic leakage, the pouch was salvaged, with 80% of patients undergoing surgical revision with relaparotomy and transanal suture. Patients with pouch necrosis underwent relaparotomy with removal of the pouch and a terminal colostomy. In all cases of intra‐abdominal abscess without anastomotic leakage, radiologically controlled percutaneous drainage was carried out. Conclusion Anal function can usually be saved after anastomotic leakage by salvage surgery without increase in mortality.     

A 5-cm colonic J pouch colo-anal reconstruction following anterior resection for low rectal cancer results in acceptable evacuation and continence in the long term

Background Optimal treatment for low rectal cancer is total mesorectal excision, with most patients suitable for low colo‐rectal or colo‐anal anastomosis. A colon pouch has early functional benefits, although long‐term function, especially evacuation, might mitigate against its routine use. The aim of this study was to assess evacuation and continence in patients with a colon pouch, and to examine the impact of possible risk factors. Methods In 1998, all 102 surviving patients with a colon pouch, whose stoma had been closed for more than one year, were sent a postal questionnaire. A composite incontinence score was calculated from questions on urgency, use of a pad, incontinence of gas, liquid or faeces; and a composite evacuation score from questions on medication taken to evacuate, straining, the need and number of times returned to evacuate. Results The response rate was 90% (50 M, 42 F), with a median age of 68 years (IQR 60–78) and median follow‐up of 2.6 years (IQR 1.7–3.9). The anastomosis was 3 cm or less from the anus in 45/92 (49%), and incontinence scores were worse in this group (P = 0.001). There were significantly higher incontinence scores in females (P = 0.014). Age, preoperative radiotherapy, part of colon used for anastomosis, postoperative leak and length of follow‐up had no demonstrable effect on either score. Conclusion Gender and anastomotic height were the only variables which influenced incontinence. Ninety percent of patients reported that their bowel function did not affect their overall wellbeing, and none would have preferred to have a stoma.

Similar outcome after colonic pouch and side-to-end anastomosis in low anterior resection for rectal cancer: a prospective randomized trial

OBJECTIVES: To compare a colonic J-pouch or a side-to-end anastomosis after low-anterior resection for rectal cancer with regard to functional and surgical outcome. SUMMARY BACKGROUND DATA: A complication after restorative rectal surgery with a straight anastomosis is low-anterior resection syndrome with a postoperatively deteriorated anorectal function. The colonic J-reservoir is sometimes used with the purpose of reducing these symptoms. An alternative method is to use a simple side-to-end anastomosis. METHODS: One-hundred patients with rectal cancer undergoing total mesorectal excision and colo-anal anastomosis were randomized to receive either a colonic pouch or a side-to-end anastomosis using the descending colon. Surgical results and complications were recorded. Patients were followed with a functional evaluation at 6 and 12 months postoperatively. RESULTS: Fifty patients were randomized to each group. Patient characteristics in both groups were very similar regarding age, gender, tumor level, and Dukes' stages. A large proportion of the patients received short-term preoperative radiotherapy (78%). There was no significant difference in surgical outcome between the 2 techniques with respect to anastomotic height (4 cm), perioperative blood loss (500 ml), hospital stay (11 days), postoperative complications, reoperations or pelvic sepsis rates. Comparing functional results in the 2 study groups, only the ability to evacuate the bowel in <15 minutes at 6 months reached a significant difference in favor of the pouch procedure. CONCLUSIONS: The data from this study show that either a colonic J-pouch or a side-to-end anastomosis performed on the descending colon in low-anterior resection with total mesorectal excision are methods that can be used with similar expected functional and surgical results.     

Perineal colostomy with antegrade continence enemas as an alternative after abdominoperineal resection for low rectal cancer

Some young and active patients requiring abdominoperineal resection for rectum cancer ask for an alternative of an abdominal colostomy. We analysed the results after a combination of a perineal colostomy and antegrade continence enemas (ACE). Fifteen patients have been operated between 1999 and 2004. Follow-up was >six months in 12 patients with a mean of two years and with a maximum of 55 months. The QLQ-C30 (version 3) and CR 38 questionnaires of the EORTC have been used to evaluate quality of life aspects. Five out of 15 patients presented complications: infection of the caecal conduit (2), small bowel obstruction (1), prolapse of the perineal colostomy (1), eventration (1), urologic complications (2). ACE are still used by all patients. The volume needed was 400 ml and duration of irrigation was 30 minutes (15-45 minutes). The median score for faecal incontinence was 0 ; faecal pseudocontinence was obtained by 7/12 patients. The scores for all aspects of functioning were excellent, as well as the score for body image. The general health status and quality of life were estimated at 75% from normal value. The procedure is simple and can be performed in one operative session. A perineal colostomy with ACE seems to be a valuable and less expensive alternative for an abdominal colostomy, and certainly for total anorectal reconstruction.

Recurrent rectal carcinoma after anterior resection and rectal stapling

Nine local recurrences have been diagnosed in 38 patients with carcinoma of the rectum operated on with anterior resection using the EEA-stapling instrument. The characteristics of these recurrences have been compared with those of other authors, currently a total of 27 recurrences. The presence of a locally advanced growth with extramural spread, a distal location and a short margin of clearance seems to increase the risk of local recurrence, with often distressing symptoms. It is proposed that even if the EEA-stapler offers technical possibilities for anterior resection in these growths, this operation should be restricted to less advanced tumours.     

Randomized comparison of straight and colonic J pouch anastomosis after low anterior resection.

OBJECTIVE. The authors compared clinical bowel function and complications of a low anterior resection with either a straight or colonic J pouch anastomosis. SUMMARY BACKGROUND DATA. Urgency and frequent bowel movements after rectal resection with a low anastomosis have been related to the loss of rectal reservoir function. Reconstruction with a colonic J pouch possibly can obviate some of this dysfunction. Earlier reports have been favorable, but they must be verified in randomized trials. METHOD. One hundred patients with rectal cancer in whom a sphincter-saving procedure was appropriate were randomized to reconstruction with either a straight or a colonic J pouch anastomosis. RESULTS. The incidence of symptomatic anastomotic leakage was lower in the pouch group (2% vs. 15%, p = 0.03). Eighty-nine patients could be evaluated after 1 year. The pouch patients had significantly fewer bowel movements per 24 hours, and less nocturnal evacuations, urgency, and incontinence. Overall well-being owing to the bowel function was rated significantly higher by the pouch patients. CONCLUSION. Reconstruction with a colonic J pouch was associated with a lower incidence of anastomotic leakage and better clinical bowel function when compared with the traditional straight anastomosis. Functional superiority was especially evident during the first 2 months.

Functional outcome after low anterior resection for rectal cancer using the colonic J-pouch

The functional outcome after low anterior resection (LAR) using the colonic J-pouch was compared with that after LAR using straight anastomosis. Colonic J-pouch construction was performed in 58 patients who underwent resection of tumors located 5–10 cm from the anal verge (J-pouch group). Functional assessment was performed 1 year postoperatively. Clinical function was evaluated using a scoring system, while physiologic sphincter and reservoir function were evaluated by anorectal manometry. The historical control group consisted of 20 patients who underwent LAR with straight anastomoses (straight group). The functional score of the J-pouch group was significantly better than that of the straight group. Although sphincter function was similar in the two groups, reservoir function was significantly better in the J-pouch group than in the straight group. These results demonstrated that the functional outcome following LAR for rectal cancer is improved by the colonic J-pouch construction.
