Recurrence following stapled coloproctostomy for carcinomas of the mid portion of the rectum.

A retrospective analysis of 90 patients who underwent a curative surgical resection for a carcinoma of the middle third of the rectum was carried out to determine the preliminary recurrence rates associated with stapled coloproctostomy. Acknowledging the obvious limitations of this preliminary report, the liberal use of restorative resections for these lesions does not appear to be resulting in an obvious increase in tumor recurrence, and the use of the circular intraliminal staplers has significantly decreased the number of abdominoperineal resections required to treat these lesions. We will continue to use stapled coloproctostomy for the majority of these lesions; however, definitive statements regarding the over-all effect of this approach upon survival time await further studies incorporating larger numbers and longer follow-up studies.

Colocolostomy and coloproctostomy utilizing the circular intraluminal stapling devices.

Coloproctostomy or colocolostomy by peranal insertion of a circular stapling device was performed on 265 patients between January 1978, and June 1981. A low anterior resection was performed in 174 patients. Stapler-related technical complications occurred in 52 patients (20 per cent). Complementary transverse colostomies were performed in 11 patients, of which seven were performed on the first 30 patients. Intraoperative complications occurred in 18 patients (7 per cent). Twenty-six major postoperative complications occurred (10 per cent), and clinical anastomotic leaks occurred in eight patients (3 per cent). Four postoperative deaths occurred (1.5 per cent). This study concludes that (1) coloproctostomy or colocolostomy can be safely performed by transanal insertion of a circular stapling device, (2) these instruments allow a sphincter-preserving procedure to be performed for lesions in the low and midrectum (5 to 10 cm from the anal verge) with an acceptable early morbidity and mortality, and (3) the majority of stapler-related technical complications can be managed without protecting colostomy.

Restorative proctocolectomy with ileal reservoir and ileoanal anastomosis.

An initial experience with a technique of restorative proctocolectomy utilizing a rectal mucosectomy, total colectomy, and ileal reservoir (Parks S-pouch) with ileoanal anastomosis for patients with ulcerative colitis and familial polyposis is presented. Although there were no deaths, significant morbidity did occur and was attributed to the use of a temporary loop ileostomy which may not be necessary. Early functional results are promising and to date, patient satisfaction is very high.

Villous adenomas of the rectum: the accuracy of clinical assessment.

To avoid an unnecessary radical operation, it is important for surgeons to identify a clinically benign villous tumor of the rectum, especially in the middle third area, where a transanal approach may not be feasible. If the high accuracy of this clinical impression can be achieved, alternative methods such as piecemeal snare excision, or electrocoagulation, or both are justified. To evaluate the diagnostic accuracy of a benign rectal villous tumor, 151 patients with totally excised rectal tumors were reviewed. All of these patients had soft and nonulcerated lesions and were judged to be benign. Induration and ulceration of the lesions signified malignancy and were excluded. One hundred and fourteen patients (76%) had benign villous adenomas, 23 patients (15%) had superficial carcinomas, and 14 patients (9%) had invasive carcinomas. Hence the accuracy of detecting a clinically benign villous tumor of the rectum was 91%. This is high enough to avoid a more radical procedure when the clinical impression is that of a benign villous tumor of the rectum.

Perianal endometrioma: report of five cases.

One of the gynecologists' commonest findings at pelvic laparotomy is endometriosis. Despite the fact that the presence of endometrial tissue in ectopic locations is commonplace, the finding of a perianal endometrioma is no more than a surgical curiosity. Very few cases have been reported. The present report describes five such verified cases. Interestingly enough, only two of the five cases were diagnosed preoperatively. The pathogenesis of endometriosis has been, and continues to be, controversial. The prevailing theories include 1) transtubal regurgitation of menstrual blood, 2) the coelomic metaplasia doctrine, 3) lymphatic dissemination, and 4) hematogenous spread. Pathologically the lesions may vary grossly from red-blue to yellowish-brown implants, ranging in size from microscopic to 1-2 cm in diameter. The definitive histologic diagnosis requires two of the following three features-glands, stroma, and hemosiderin pigment. The clinical manifestations depend upon the functional activity of the involved tissue and may range from an asymptomatic mass to the classic presentation of a mass increasing in size and becoming acutely painful during menstruation but subsiding in size and decreasing in tenderness between menstrual periods. These protean manifestations are readily illustrated by the cases presented. Anatomically the lesions are usually found in old episiotomy scars. Because these lesions are usually readily accessible, and because their exact nature is frequently not known preoperatively, the treatment of choice is local excision. Complementary hormonal therapy has been suggested, but the value of such treatment is not yet proven. Ovarian ablative therapy is also considered.

Endorectal advancement flap for treatment of simple rectovaginal fistula.

An endorectal advancement flap technique has been utilized in 35 women for repair of "simple" rectovaginal fistulas, i.e., those of low or midseptal location, less than 2.5 cm in diameter, and of traumatic or infectious etiology. Colostomy is unnecessary. Concomitant sphincteroplasty for correction of associated anal incontinence is readily accomplished. Results are excellent with healing ultimately achieved in 32 of 35 women (91 per cent).

Abdominoperineal resection for recurrent cancer following anterior resection.

Cases are reviewed of 12 patients who had abdominoperineal resections for cancer recurrence subsequent to anterior resection. Although this procedure is technically more difficult, we experienced no mortality or significant morbidity, and the postoperative hospital stay was similar to that of patients who received an abdominoperineal resection as a primary procedure. Although we have no long-term cures, at least significant palliation can be achieved in selected patients who have no evidence of distant metastases.
