A retrospective study of colostomy closures was prompted by recent reports detailing frequent postoperative complications. In a series of 125 intraperitoneal colostomy closures there was a low incidence of complications. There were no anastomotic breakdowns, fistulas, or deaths. We conclude that closure of a well healed colostomy is a safe operation, the success of which is determined by the careful technic with which it is performed.
Local vasoconstriction produced by infiltration of a dilute solution of epinephrine during parotidectomy allows a more rapid and accurate dissection.
The colonoscopic management of 86 patients with polypoid lesions of bleeding from the colon of intermittent nature is discussed. There were 145 polyps found in 85 of these patients. Adenomatous polyps occurring in the sigmoid colon above the reach of the standard sigmoidoscope was the most common finding and pathological diagnosis. Adenocarcinoma of the colon occurred in two patients and invasive carcinoma of a polyp was found in three other patients. Five other patients had polyps that demonstrated a carcinoma in situ. The definitive treatment of these complicated polyps is outlined. The importance of barium enema examination on follow-up of polyp and carcinoma patients and on patients with polyps found at standard sigmoidoscopy is stressed. The possibility of colonoscopic follow-up in lieu of colectomy and ileoproctostomy is suggested for patients with multiple polyps of the colon who do not belong to the familial polyposis group.
