title: Conventional pneumoperitoneum compared with abdominal wall lift for laparoscopic cholecystectomy.
abstract: We have compared, in a randomized study, conventional carbon dioxide pneumoperitoneum with abdominal wall lift in 25 patients undergoing laparoscopic cholecystectomy. Intra-abdominal pressure (IAP) (11 (SD 2) mm Hg vs 2.7 (9) mm Hg) (P < 0.01) and total amount of carbon dioxide used (40 (23) litre vs 9 (7) litre) (P < 0.001) were significantly less with abdominal wall lift. Pulmonary compliance was significantly greater (P < 0.01) in the abdominal wall lift group throughout operation. During the first 15 min of insufflation, arterial pressures were lower with abdominal wall lift (P < 0.05). In the conventional pneumoperitoneum group, femoral vein pressure increased (P < 0.01) and remained elevated for 3 h in the recovery room. Postoperative drowsiness was of significantly longer duration in the conventional pneumoperitoneum group than in the abdominal wall lift group (98 (46) min vs 13 (34) min) (P < 0.01). Postoperative nausea and vomiting and right shoulder pain occurred more often in patients with conventional pneumoperitoneum (P < 0.05). We conclude that the benefits of abdominal wall lift may be attributed to avoiding excessive carbon dioxide and high IAP.
