摘要:

&NA;Internal intussusception of the rectum is described as a specific clinical entity. A review of the cases treated at the Colon and Rectal Surgery Service at Jewish Hospital is presented, along with the specific diagnostic procedures that have been developed and the surgical technique that allows relatively simple correction of the problem. It is believed that this entity presents commonly to the practitioner of colon and rectal surgery, and specific diagnoses and therapy will be an important addition to the armamentarium of the colon and rectal surgeon.

摘要:

&NA;The structure of the anal canal was examined in histology slides. Hemorrhoids are normal features of the human anatomy. They are pads that bulge into the lumen. Hemorrhoids have three parts: 1) the lining, which can be mucosa or anoderm; 2) the stroma with blood vessels, smooth muscle, and supporting connective tissue; and 3) the anchoring connective tissue system, which secures the hemorrhoids to the internal sphincter and the conjoined longitudinal coat. The anchoring and supporting connective tissue system deteriorates with aging. The hemorrhoids not only bulge, but descend into the lumen. This becomes observable in the third decade of life, with individual differences. The veins become distended as they lose their support. The descended loose lining becomes more sensitive to pressure from straining and to trauma from the stool. There can be a stasis in the veins, with clot formations and swelling or erosions of the lining, with bleeding. The hemorrhoids become symptomatic.

摘要:

&NA;A controlled, randomized study of the efficacy of a plastic wound ring drape (Opdrape, Triplus) to prevent contamination and infection in elective colorectal operations is reported. Seventy patients were operated upon with the wound ring drape and 70 patients without. All patients received preoperative systemic antibiotic prophylaxis. Abdominal wound infection was observed in seven of 70 (10 per cent) patients with the wound ring drape and six of 70 (9 per cent) without (N.S.). An operative swab for bacteriologic evaluation was obtained from 85 per cent of the wounds. There was no evidence that the drape protected the wound from contamination with intestinal bacterial flora. It was concluded that the wound ring drape prevents neither contamination nor infection.

摘要:

&NA;Twelve cases of acute solitary diverticulitis of the cecum or ascending colon are reviewed. This is frequently indistinguishable from acute appendicitis preoperatively and is often mistaken for carcinoma at laparotomy. There are subtle clinical features that may help to suggest the diagnosis both before and during surgery. If diagnosed preoperatively, it can be treated effectively with broad spectrum antibiotics without surgical intervention. When diagnosed intraoperatively, hemicolectomy can often be avoided. Appendectomy should be done if resection is not performed.

摘要:

&NA;An hypothesis is presented to explain the changing pattern of colorectal cancer seen within the United States and other western countries in the last 30 years, the simultaneous increase of right‐sided colonic cancer and disappearance of rectal cancer. Review of experimental and epidemiologic data suggests that this change may be due to a new systemic deficiency of the trace element selenium. This deficiency has arisen not just from decreased consumption of selenium in the last 30 years, but also from increased consumption of zinc and fluoride, which may antagonize the effect of selenium.

摘要:

&NA;The healing of both rabbit ileal and colonic infected anastomoses has been investigated. Infection was induced by implanting a capsule with human fecal material in the anastomotic area. Infection did result in lowered bursting pressures, which effect was most pronounced in ileum seven days postoperatively. In general, the average hydroxyproline levels in and around infected anastomoses were lower than the hydroxyproline concentrations measured around noninfected anastomoses. This difference was most significant in the segment proximal to the ileal anastomosis seven days after operation, in the segment distal to the colonic anastomosis three days after operation, and in the segment proximal to the colonic anastomosis seven days after operation. It is concluded that infection interferes with the early stages of the healing sequence in rabbit intestinal anastomoses, profoundly affecting collagen metabolism. Our work does not support recent publications that report an unchanged or even increased wound strength under infected conditions.
