摘要:

&NA;One hundred thirteen patients underwent anterior resection for complete rectal prolapse betwen 1968 and 1980. These patients were followed for an average of seven years; recurrence developed in eight patients (9 percent). Recurrences were found to occur at three months to eight years postoperatively, and the probability of a recurrence at two, five, and ten years was 3 percent, 6 percent, and 12 percent, respectively. Operative mortality was 1 percent and morbidity was 29 percent. Low anterior resectioin, with anastomosis in the deperitonealized portion of the colon, was found to increase morbidity without significantly decreasing recurrence when compared with high anterior resection. The effects of repair on patient continence were unpredictable. High anterior resection is preferable to low anterior resection in the treatment of rectal prolapse and offers results comparable to those of other repairs currently being performed.

摘要:

&NA;Pelvic and perineal recurrences of cancer after rectal amputation are frequent, often isolated, and thus directly responsible for a fatal outcome by local decompression accidents or infection. This study explores the patterns of recurrence after “curative” operation for rectal cancers. One hundred thirteen patients who underwent abdominoperineal resection are reviewed: there were 36 local recurrences,i.e., an incidence of 31.8 percent. About 70 percent of these recurrences occurred within two years after surgical treatment. Low level of tumor in the rectum, local spread into perirectal fat or serosa, lymph node involvement, and histologic grade of malignancy were the only factors that were statistically related to local recurrence. The strategy for careful follow‐up of patients at risk is outlined and a plea is made for a controlled trial of postoperative radiotherapy.

摘要:

&NA;In a retrospective evaluation of 1244 consecutive barium enemas performed at two hospitals over a five‐year period (1979 to 1984), colonic diverticula were found in 177 (14.2 percent). The prevalence among the Ashkenazi Jews was 19.7 percent, among the Sephardi and Oriental Jews, 16 percent, and among the Arabs, 9.5 percent. Comparing these figures with the results of a similar study performed ten years ago, it becomes obvious that the prevalence of diverticular disease in the Ashkenazi group remained the same, while there was a three‐fold increase among Sephardi and Oriental Jews, and a seven‐fold increase among Arabs. It is postulated that, in less than one generation, diverticular disease will be equally frequent among all ethnic groups in Israel.

&NA;Biofeedback training is proposed as rehabilitative training for patients with permanent colostomoies to help them achieve fecal continence. The results of a preliminary study of 18 patients are reported.

摘要:

&NA;Colorectal surgeons are frequently faced with rectocele patients who have distressing bowel difficulty and anorectal complaints. In 1977, a new technique of transrectal repair of rectocele operating through a standard Fansler operating speculum was developed. The principle of the repair is based on the technique of Sullivan, as described elsewhere. The main difference is in dealing with the mucosal prolapse. A total of 355 cases of transrectal repair of rectocele was compiled for study covering a period from 1977 to 1982. Ninety‐eight percent of patients have improved. Only 2 percent reported no improvement after surgery. There was a 5.6 percent overall infection rate. With refinement of the technique, no infection has been observed in the last 96 cases of the series.

摘要:

&NA;Three cases of small‐cell carcinoma of the rectum are presented. Our conclusions are as follows: 1) small‐cell carcinoma and carcinoid tumor of the rectum might have a common origin; 2) indications for surgical intervention for small‐cell carcinoma of the rectum should be considered seriously; 3) small‐cell carcinoma of the rectum should be classified as an aggressive type of rectal tumor that metastasizes easily to distant organs.

摘要:

&NA;Two cases of highly malignant tumors, one originating in the sigmoid colon and the other in the rectum, are presented. Both tumors showed light microscopic, electron microscopic, and immunohistochemical evidence of multidirectional differentiation. The tumors were composed mainly of undifferentiated cells, but focally merging into areas with adenocarcinomatous and squamous differentiation. Ultrastructurally and histochemically, a predominant endocrine differentiation was present in the undifferentiated areas of the tumors. These two cases lend further support to the recent concept of a pluripotential stem cell in the mucosa of the gastrointestinal tract capable of differentiation in several directions.

摘要:

&NA;Gastrointestinal tuberculosis has declined markedly in frequency since the introduction of antituberculous therapy. As a result, the diagnosis is often delayed in North American patients. Segmental colonic disease, especially in the absence of pulmonary tuberculosis, is often difficult to differentiate from Crohn's disease or a neoplasm. We describe a case of colonic tuberculosis mimicking carcinoma of the hepatic flexure of the colon.
