&NA;Mechanical circular stapling devices offer several advantages in the formation of low rectal anastomoses. The author's aim was to compare the quality of rectal anastomoses created in dogs using the two commonly available staple suture guns, the EEA and SPTU. Thirty dogs, 15 with each gun, had rectal division and anastomosis. The first 20 dogs (ten EEA and ten SPTU) were sacrificed at eight days. Anastomotic integrity was assessed using plain x‐ray, barium enema, and postmortem examination and pressure studies. The remaining ten dogs, five in each group, were sacrificed at 48 hours, and the anastomoses were inspected and examined histologically. Eleven of 15 anastomoses in the EEA group showed evidence of breakdown compared with only three of 15 in the SPTU group (P<0.02). It is concluded that the SPTU gun created a more satisfactory anastomosis and that this was probably due to its staples having an adjustable closure.

摘要:

&NA;The authors compared two groups of patients receiving oral 5% mannitol for bowel preparation to see whether the volume of rectal effluent and quantity of bowel preparation could be maintained by a smaller oral mannitol intake supplemented by an intravenous infusion. Nineteen patients drank 2‐3 1 5 % mannitol, supplemented by an intravenous infusion of N/saline (intravenous Group) and 19 patients drank 4‐5 1 5 % mannitol (oral group). The volume of rectal effluent and the quality of bowel preparation was the same in both groups. The loss of sodium in the oral group was corrected by the intravenous infusion, but the infusion resulted in greater water retention. There was no reduction in the incidence of vomiting between the two groups.

摘要:

&NA;Experience with a subcutaneous injection reservoir in patients receiving intraphepatic chemotherapy for metastatic adenocarcinoma to the liver from the colon and rectum is presented. Details of technique are described. It is postulated that the implantable subcutaneous reservoir adds considerably to the quality of life of these patients.

摘要:

&NA;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).

摘要:

&NA;To study new collagen formation in the healing of anastomoses in the right colon, five male Sprague‐Dawley rats had single‐layer colonic anastomosis performed. Five additional rats had suture of the colon with interrupted sutures without transection of the colon. Ten animals served as controls. One week after surgery, animals were given3H‐proline repeatedly to label new collagen formation during the second and third weeks. Animals were sacrificed three weeks after suturing or anastomosis. Two‐ or 10‐mm segments were precisely excised on either side of the suturing or anastomoses. Total collagen and its total radioactivity were measured per segment. Collagen hydroxyproline and its radioactivity increased (100 per cent) only within 1 cm of the anastomosis or suture alone. No local or distant decrease in collagen was observed. Collagen formation in colonic wounds appears to be a local process.

摘要:

&NA;In eight years at Cook County Hospital, 42,000 barium enemas, 16,325 proctosigmoidoscopies, and 1207 colonoscopies were performed. All endoscopic procedures were done by the house staff. There were three perforations due to proctosigmoidoscopy, with one death; three perforations due to colonoscopy, with no deaths; and seven perforations due to barium enema, with no survivors. The adjuvant effect of barium sulfate is proposed as the most likely cause for this excessively high mortality in barium‐enema perforation.

摘要:

&NA;Ninety patients were included in this prospective randomized trial. Each required elective colorectal surgery and was prepared for operation with oral preoperative antibiotic therapy, systemic peroperative therapy, or by a combination of both. The number of each type of septic postoperative complication and their total did not differ between the group treated by oral antibiotics prior to operation and the group treated peroperatively with systemic antibiotic therapy. The total number of septic complications (wall abscesses, fistulas, subdiaphragmatic abscesses, septicemia, peritonitis), however, was significantly less (P<0.05) in the group treated by both preoperative oral antibiotics and peroperative systemic antibiotic therapy (3.3 per cent) than in either groups treated only orally preoperatively (30 per cent) or by systemic antibiotic therapy during the operation (23 per cent). The combination of oral antibiotic therapy prior to operation and of systemic peroperative antibiotic therapy, therefore, presents the most effective prophylactic effectiveness.

摘要:

&NA;An immunoperoxidase staining method was used to study specific immunoglobulin‐containing cells in the intestinal mucosa of children who presented with features suggestive of Hirschsprung's disease. No evidence was found to substantiate the hypothesis of an immunologic component in the etiology of Hirschsprung's disease. The megacolon in this condition had an increased proportion of IgG‐containing cells and a reduced proportion of IgA‐containing cells when compared with normal and unobstructed colon; this may be a reflection of an abnormal mucosal immune defense leading to susceptibility to the enterocolitis found in Hirschsprung's disease. Numerous lipofuscin‐bearing macrophages were seen in the colonic mucosa of children with anal stenosis who were given anthraquinone laxatives for varying periods. The possibility that this represents an early stage of melanosis coli, as well as the likelihood of anthraquinones contributing to the pathogenesis of acquired megacolon, are considered.
