Laparoscopic prosthesis fixation rectopexy for complete rectal prolapse.

Five women aged 64–81 years with complete rectal prolapse and incontinence were treated by laparoscopic mobilization of the rectum and posterior fixation to the presacral fascia using Marlex mesh. Mobilization was carried out with standard straight laparoscopic instruments in the first two patients (operating times 3·5 and 4·5 h) and with coaxial curved instruments and ultrasonic dissection in the succeeding three (operating times 2·5, 2·0 and 2·5 h). Restoration to full continence (grade 1) was observed in two patients and to grade 2 in a further two. No recurrence of the prolapse occurred during follow‐up of 4–27 months.

Intraoperative cholangiography during laparoscopic cholecystectomy

An audit of routine intraoperative cholangiography in a consecutive series of 496 patients undergoing laparoscopic cholecystectomy has been performed. Cannulation of the cystic duct was possible in 483 patients (97%). The use of portable, digitized C-arm fluorocholangiography was vastly superior to the employment of a mobile x-ray machine and static films in terms of reduced time to carry out the procedure and total abolition of unsatisfactory radiological exposure of the biliary tract. Repeat of the procedure was necessary in 22% of cases when the mobile x-ray equipment was used. Aside from the detection of unsuspected stones in 18 patients (3.9%), routine intra-operative cholangiography identified four patients (0.8%) whose management would undoubtedly have been disadvantaged if intraoperative cholangiography had not been performed.

Abdominal wall lift

SummaryA method of abdominal wall lift has been developed and evaluated clinically in this unit during the past 18 months. It permits the conduct of laparoscopic procedures at an intraabdominal pressure of 6–8 mm Hg. The technique was introduced for laparoscopic surgery in patients with preexisting cardiac disease and chronic bronchitis. The procedure, by lifting both the abdominal wall and the falciform ligament together, also elevates the central portion of the liver (segments 3–5), thereby improving the surgical exposure. For this reason it is now also used in fit patients with ptotic livers or hypertrophied quadrate lobes undergoing laparoscopic cholecystectomy and common bile duct exploration, and to facilitate left subhepatic exposure in patients during laparoscopic antireflux surgery and vagotomy.

Endoscopic ultrasonic dissection for thoracoscopic and laparoscopic surgery

SummaryA specifically designed handpiece has been developed for ultrasonic dissection of tissues and organs during minimal-access surgery. The experimental prototype has been evaluated in major endoscopic operations on the esophagus, colon, and rectum (n=19). The benefits documented by this initial experience include increased dissection efficiency of extensive fibroareolar attachments, safe exposure of major vascular pedicles (especially those located in mesocolic fat), greatly reduced risk of major hemorrhage, and decreased operating time.
