&NA;A method for constructing a continent colostomy has been tested in dogs. The sigmoid colon was divided and the distal end closed. The proximal end was used for constructing the colostomy. Approximately 5 cm proximal to the colostomy, a short segment of the sigmoid wall was intussuscepted into the bowel lumen and secured in position by use of electrocauterization and silk sutures placed through the intestinal walls. The intussuscepted “nipple” projecting into the lumen of the bowel measured 3‐5 cm.Ten dogs were provided with this type of colostomy. The bowel was emptied once or twice a day by the use of a wide‐bore plastic catheter and irrigation. All dogs were continent from the time of operation until they were sacrificed one to eight weeks later. In two dogs abscesses developed around the colostomy, but in the other dogs no surgical complication was found. In six animals bezoars (hairballs) in the colon dislocated the nipple valve and made emptying difficult. For this reason the observation time has not exceeded eight weeks.

摘要:

&NA;In five dogs with continent colostomies constructed according to a method described previously the dynamics of the “nipple valve” were studied electromanometrically by recording simultaneously the intracolonic pressure and the “withdrawal” pressure. A high‐pressure zone was recorded in the nipple valve and the length of the zone corresponded roughly to the anatomic nipple length. The maximal pressures in the high‐pressure zones varied considerably in different dogs as well as in the same animal from time to time. When the intraluminal pressure of the bowel was high, as occurs before emptying, the pressure in the high‐pressure zone was higher. After emptying, when the intraluminal pressure was low, the pressure in the high‐pressure zone diminished, but remained higher than the intraluminal pressure. The minimum pressure in the high‐pressure zone always exceeded that simultanously recorded in the bowel lumen. In acute experiments it was found that a nipple length of at least 2.5 cm was necessary for achieving continence for air.

摘要:

&NA;Late morbidity after abdominoperineal and low anterior resections for rectal cancer was analyzed during a 10‐year period, where these operations were used for cure, the latter being performed whenever it was possible to resect the rectum 5 cm below the tumor.The incidences of abdominal‐wall fistulas, ventral hernias, mechanical ileus and sexual impotence were not less after abdominoperineal resection than after low anterior resection. The former carried other late complications, such as hernia about the colostomy, atresic colostomy, eczema around the colostomy, perineal hernia, and fistula and abscess, while the only other complication after low anterior resection was persisting fistula after anastomotic leakage.The results support the statement that low anterior resection for cure of rectal cancer should be used whenever possible.

摘要:

&NA;Analysis of the responses to an attitudinal questionnaire answered by 130 surgeons active in colorectal surgery indicates that only 52 per cent consider themselves proponents of operative coloscopy. Despite the difficulty in accurately assessing attitudes, a slight trend of diminishing enthusiasm concerning coloscopy is noted. A too‐low yield of additional polyp detection and a too‐high risk of contamination were the objections most frequently raised by antagonists. While this survey indicates also that operative coloscopy performed in conjunction with colotomy and polypectomy remains a useful and rational procedure in the minds of most surgeons, its future application promises to be severely limited by the burgeoning use of flexible fiberoptic colonoscopy.

摘要:

&NA;A rare case of rectal cavernous hemangiorna is presented. Atypical distribution of pelvic phleboliths submucosal masses and narrowing of the barium‐filled rectum are characteristic roentgenologic signs. Arteriography is recommended to delineate the full extent of any gastrointestinal hemangioma. However, large, cavernous hemangiomas may not always show the anticipated arteriographic findings. Therefore, prolonged venous phase films during arteriography and venography with compression of the inferior vena cava may be useful in opacifying these larger lesions in future cases.

摘要:

&NA;A case of cholecystocolonic fistula and sigmoidal obstruction is presented. Initial surgical management was accomplished by colotomy with lithotomy, cholecystectomy, and concomitant exteriorization of the fistula site in the colon as a diverting colostomy. The authors recommend routine use of exteriorization of a fistula site as a diverting colostomy with cholecystectomy or cholecystostomy for initial treatment for this unusual manifestation of biliary disease.
