摘要:

&NA;One hundred eighty left colonic single‐layer end‐on anastomoses performed on 90 rats by microsurgical techniques, using polydioxanone monofilament absorbable sutures, were examined histopathologically and microangiographically at nine different times, from two to 180 days. There was no anastomotic leakage. The vascular state after suturing and the evolution of the neovascularization are described. The neovascularization appeared to follow the same process of evolution as tissue restoration. It began early, was greatest on the seventh day, and diminished thereafter. When granulation tissue was narrow, the anastomoses were barely hypervascular, the neovascularization assured by submucosal plexus. A voluminous granulation tissue was hypervascular, had a slower evolution, and neovascularization was then assured above all by the peritoneal formations adherent to the suture.

摘要:

&NA;In order to investigate the safety of abdominal irrigation with polyvinylpyrrolidone iodine (PVPI), the abdominal cavities of normal rats were irrigated with the highest nonlethal dose. Samples of the peritoneal fluid were taken before and 1, 2, and 4 hours after irrigations. Control studies were done with saline. After irrigation with PVP1, the protein concentration in the peritoneal fluid showed a 40‐fold increase, compared with only a doubling after saline irrigations. Irrigation with PVPI causes serious peritoneal damage, and should therefore not be performed as a prophylactic procedure.

摘要:

&NA;A biofragmentable bowel anastomosis ring (BAR) for sutureless intestinal anastomosis is described with the laboratory results comparing the BAR to sutured and stapled anastomoses. There was equivalent healing with all three methods of anastomosis. However, “burst” pressure was highest at day zero and overall necrosis was least with the BAR. By virtue of these findings and being sutureless, it is hoped that the limits of safe bowel anastomosis can be extended.

摘要:

&NA;Golytely®, an oral gut lavage solution, was compared with a standard bowel cleansing preparation in patients undergoing elective colonic surgery. Sixty patients were randomly assigned to either a one‐day preparation with Golytely and bisacodyl or a standard method using a three‐day clear liquid diet, cathartics, and enemas. Colon cleansing was better with Golytely (100 percent optimal cleansing vs. 64 percent,P<0.05). Patients receiving Golytely had less weight loss and found this preparation more tolerable. Quantitative stool cultures before and after preparation and intraoperatively were not significantly different between the two preparations. In this surgical bowel preparation study, Golytely and Bisacodyl were found to be safe, rapid, and effective. The preparation was well tolerated by patients and has become our preferred method of colonic cleansing.

摘要:

&NA;One hundred eighty‐nine patients with anal fistula treated within an eight‐month to seven‐year period by anal fistulectomy and rectal mucosal advancement are presented. An 80 percent follow‐up revealed a 90 percent asymptomatic group and a ten percent group who had minor symptoms. Eight percent of the symptomatic patients had minor soiling; 7 percent were incontinent for gas, and 6 percent were incontinent for loose stools. No patient was incontinent for solid feces. There was a 1.5 percent rate of recurrent anal fistula comparable to other techniques.

摘要:

&NA;A prospective study was undertaken to investigate the feasibility and diagnostic yield of ileoscopy as an extension of total colonoscopy. The distal 15 to 40 cm of the terminal ileum were visualized in 400 of 555 consecutive patients submitted to total colonoscopy (72 percent). Intubation of the terminal ileum was not successful in 42 patients (8 percent), not tried in 63 (11 percent), and hampered by inadequate colonic cleansing in 50 (9 percent). We observed 13 patients with terminal ileitis and seven rare findings such as nonspecific ileal ulcer or non‐Meckelian diverticulum, etc., adding to a total of 20 pathologic findings in 400 examination (5 percent). In a further group of 98 patients, useful diagnostic information was gained by the demonstration of normal ileal findings, making ileoscopy clinically valuable in 118 of 400 examinations (29.5 percent) in this series. We suggest routine endoscopy of the terminal ileum in all patients with suspected or established inflammatory bowel disease and/or persistent diarrhea, lower gastrointestinal tract bleeding, or irritable bowel syndrome, in whom the diagnostic procedure includes colonoscopy. In patients with colorectal tumors or polyps, the diagnostic yield will be unrewarding.

摘要:

&NA;The reflux from the continent ileostomy reservoir was studied with radiologic and pressure recording techniques in ten patients. The contrast used was poly‐iodine‐styrene with a density of 0.8 to 1.1 gm/cm3. Reflux into the afferent loop was demonstrated in all patients at a filling volume of approximately 30 percent of the maximal volume capacity of the reservoir. The magnitude of reflux increased with the increasing volume of the reservoir contents and a rise in reservoir pressure. The reflux could temporarily be influenced by antiperistaltic or isoperistaltic motor activity in the afferent loop. Although no adverse effects were seen from the amount of reflux demonstrated in the present investigation, the finding of increasing reflux with increased fullness and intraluminal pressure of the reservoir would indicate that the reservoir should be emptied at regular intervals and before high pressures are built up.
