    Notes: Abstract Background: Very few studies have been done on the consequences of pneumoperitoneum on hepatic function. At present, there is no consensus on the physiopathological hepatic implications of pneumoperitoneum. The purpose of this clinical study was to evaluate the effects of pneumoperitoneum on hepatic function in 52 patients treated with laparoscopic procedures. Methods: Thirty-two laparoscopic cholecystectomies and 20 nonhepatobiliary laparoscopic procedures were performed in 52 patients (12 men and 40 women) with a mean age of 44 years (range, 15–74). All patients had normal values on preoperative liver function tests. The anesthesiologic protocol was uniform, with drugs at low hepatic metabolism. The 32 cholecystectomies were randomized into 22 performed with pneumoperitoneum at 14 mmHg and 10 performed at 10 mmHg. All nonhepatobiliary laparoscopic procedures were performed with a pneumoperitoneum of 14 mmHg. The postoperative serologic levels of AST, ALT, bilirubin, and prothrombin time were measured at 6, 24, 48, and 72 h. The serologic changes were related to the procedure, the duration, and the level of pneumoperitoneum. Results: Mortality and morbidity were nil. All 52 patients had a postoperative increase in AST, ALT, bilirubin, and lengthening in prothrombin time. Slow return to normality occurred 48 or 72 h after operation. The increase of AST and ALT was statistically significant and correlated both to the level (10 versus 14 mmHg) and the duration of pneumoperitoneum. Conclusions: The duration and level of intraabdominal pressure are responsible for changes of hepatic function during laparoscopic procedures. Although no symptom appears in patients with normal hepatic function, patients with severe hepatic failure should probably not be subjected to prolonged laparoscopic procedures.

    Notes: Abstract Design: Evaluation of thoracoscopic splanchnicectomy and laparoscopic gastrojejunostomy as endoscopic palliative treatment of advanced pancreatic cancer. Patients and methods: Between November 1993 and September 1998 we performed 16 thoracoscopic splanchnicectomies and 6 laparoscopic gastrojejunostomies in patients with an advanced pancreatic cancer admitted to the Department of Surgery of University Hospital Rotterdam - Dijkzigt. These patients either did not achieve adequate pain control with medication or presented serious problems of gastric outlet obstruction, or both. Results: There were fourteen patients (9 men and 5 women) with mean age of 51.8 years (range 28-83), mean BMI of 21.1 (range 17.2-27.2), ASA score I in 2, II in 11, III in 1. We performed 2 left, 2 right and 4 bilateral thoracoscopic splanchnicectomies, 4 laparoscopic gastrojejunostomies and 2 combined endoscopic procedures (bilateral thoracoscopic splanchnicectomy and laparoscopic gastrojejunostomy). The overall average operation ("skin to skin") time was 86 minutes (range 75-100) for bilateral thoracoscopic splanchnicectomies, 63 minutes (range 60-65) for unilateral splanchnicectomies, 88 minutes (range 65-115) for laparoscopic gastrojejunostomies and 190 minutes (range 180-200) for the combined procedure. Blood loss was insignificant with a median of 50 ml (range 30-150). The conversion's rate to open surgery was 4.5%. There were no intraoperative complications. The overall average postoperative mobilization was in 1.9 days (range 1-4) and the overall median postoperative hospital stay was 7 days (range 2-24). There was no mortality at 30 days after endoscopic procedures and the morbidity rate was 21.4%. The postoperative analgesic requirement was considerably reduced with a successful rate was 83.3%. The resolution of gastric outlet obstruction has been complete in all laparoscopic gastrojejunostomies. Conclusions: Our results show the feasibility and safety of these minimally invasive approaches such as endoscopic palliative treatment of complications of advanced pancreatic cancer.
