Dividing the sac and suturing the peritoneum is feasible and efficient by laparoscopy. Compared with the other techniques that have previously been reported, either without any dissection of the sac or any ligature, our technique seems to be advantageous. It is not time consuming and does not require any special laparoscopic skill.
Eight cases of rectal diverticula are discussed with reference to the etiological, clinical and radiological findings. Males predominated 3:1 and the average number of diverticula in each patient was 2. Diverticulosis of the remaining colon, especially the sigmoid segment, always accompanied rectal diverticula. The average diameter of rectal diverticula was larger than that of the colonic: 2.5 cm vs. 0.5-1.0 cm. Rectal diverticula may be confused with a carcinoma at endoscopy. Surgical treatment becomes necessary if the diverticulum progresses to abscess formation and perforation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations鈥揷itations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
