    Notes: Abstract Background: The ability of laparoscopic techniques to treat malignant disease is controversial. We developed a rat model to assess metabolic and oncological effects of laparoscopic surgery. Methods: Experiment I. The postoperative body weight in 10 rats having laparoscopic bowel resection (group I), 10 rats having open bowel resection (group II) and 5 rats having anesthesia only (group III) was determined. Experiment II. Tumor take was scored in 11 rats having laparoscopic bowel resection (group IV), 11 rats having open bowel resection (group V), 6 rats having CO2 pneumoperitoneum without bowel resection (group VI) and 6 rats having anesthesia only (group VII). All rats had CC531 cancer cells injected intraperitoneally postoperatively. Results: Experiment I. Body weight loss in group I compared to group II (p〈0.036). Rats of group III lost no weight postoperatively. Experiment II. Tumor take was less in the subcutis (p=0.005), parietal peritoenum (p〈0.001) and bowel anastomosis (p=0.021) in group IV compared to group V. Tumor take was significantly greater at all sites except for subcutis in group VI compared to VII (all p〈0.022). Conclusions: Laparoscopic surgery is associated with less postoperative weight loss and less tumor take compared to open surgery. CO2 insufflation appears to increase tumor take.

    Notes: Abstract We encountered significant liver fibrosis in a healthy young patient undergoing laparoscopic cholecystectomy for symptomatic gallstone disease. Twelve months prior to cholecystectomy the patient underwent multiple extracorporeal shock-wave lithotripsy (ESWL) sessions with adjuvant oral bile-acid therapy. Since the site of fibrosis corresponded clearly to the shock-wave transmission path, which was in accordance with animal studies, it was concluded that this liver fibrosis was a side effect of biliary ESWL. Based on these findings and the literature, we conclude that further assessment of the long-term safety of ESWL is still warranted, especially in patients undergoing multiple ESWL sessions.

    Notes: Abstract Background: Thoracoscopic resection of the first through the fourth thoracic sympathetic ganglion for palmary and axillary hyperhidrosis and Raynaud's syndrome is associated with a high initial success rate. However, the reported incidence of compensatory hyperhidrosis of the trunk and legs and Horner's syndrome are high. This study assesses the results of thoracoscopic sympathectomy limited to transection of the interganglionic trunk or resection of one or two thoracic ganglia. Methods: Twenty-eight thoracoscopic sympathectomies were done for dystrophy of the hand (n=9), palmar and axillary hyperhidrosis (n=6), and Raynaud's syndrome (n=4). The extent of sympathectomy varied from interganglionic division between the second and third ganglion (n=12), to resection of the third ganglion (n=12), to resection of the second and third ganglion (n=4). Results: Sympathectomy resulted initially in relief of symptoms in all cases. Horner's syndrome did not occur. Conclusions: After a median follow-up of 11 months, two of nine patients with dystrophy judged the result of operation as good. All patients with hyperhidrosis and Raynaud's syndrome judged the result of sympathectomy as good. Compensatory hyperhidrosis was experienced by two patients with dystrophy of the hand who had removal of the second and third sympathetic ganglion.
