METHODS: Twenty-eight female pigs were anesthetized and laid in the left recumbent position. The SBI model was established by shooting at the right lower quadrant of the abdomen. The pigs were then randomized into either the laparotomy group or the laparoscopy group. All pigs underwent routine exploratory laparotomy or laparoscopy to evaluate the abdominal injuries, particularly the types, sites, and numbers of SBIs. Traditional open surgery or therapeutic laparoscopy was then performed. All pigs were kept alive within the observational period (postoperative 72 h). The postoperative recovery of each pig was carefully observed. RESULTS: The vital signs of all pigs were stable within 1-2 h after shooting and none of the pigs died from gunshot wounds or SBIs immediately. The SBI model was successfully established in all pigs and definitively diagnosed with single or multiple SBIs either by exploratory laparotomy or laparoscopy. Compared with exploratory laparotomy, laparoscopy took a significantly longer time for diagnosis (41.27 ± 12.04 min vs 27.64 ± 13.32 min, P = 0.02), but the time for therapeutic laparoscopy was similar to that of open surgery. The length of incision was significantly reduced in the laparoscopy group compared with the laparotomy group (5.27 ± 1.86 cm vs 15.73 ± 1.06 cm, P < 0.01). In the final post-mortem examination 72 h after surgery, both laparotomy and laparoscopy offered a definitive diagnosis with no missed injuries. Postoperative complications occurred in four cases (three following laparotomy and one following laparoscopy, P = 0.326). The average recovery period for bowel function, vital appearance, and food re-intake after laparoscopy was 10.36 ± 4.72 h, 14.91 ± 3.14 h, and 15.00 ± 7.11 h, respectively. All of these were significantly shorter than after laparotomy (21.27 ± 10.17 h, P = 0.004; 27.82 ± 9.61 h, P < 0.001; and 24.55 ± 9.72 h, respectively, P = 0.016). CONCLUSION: Compared with laparotomy, laparoscopy offers equivalent efficacy for diagnosing and treating SBIs, and reduces postoperative complications as well as recovery period.展开更多

Methods One hundred and eight cases of hepatolithiasis treated in our hospital from January 1986 to September 2003 were summarized and analyzed retrospectively. The primary surgery included 57 cases of biliary tract exploration and cholangiolithotomy, 26 cases of cholangiojejunostomy, and 25 cases of partial hepatectomy. Of these cases, 156 operations were performed totally. There were 36 patients undergoing two or more operations for cholangiolithiasis problem. Fiberoptic choledochoscopy was employed to examine and remove the residual stones during and after operation in all cases. Results The residual stone rates were 57.89% (33/57), 26.92% (7/26), and 24.0% (6/25) for biliary tract exploration and cholangiolithotomy, cholangiojejunostomy, and partial hepatectomy, respectively. Fiberoptic choledochoscopy was utilized pre- and post-operatively for each patient, which was performed 2 to 9 times on each case. Following the combined treatment, the rate of residual stone after operation decreased to 12.96% (14/108). Conclusions The combined surgical therapy is valuable for resolving the problem of hepatolithiasis in most of the patients. Regarding the clinical outcomes of different surgical procedures, partial hepatectomy is superior to cholangiojejuno- stomy or biliary tract exploration and cholangiolithotomy. Fiberoptic choledochoscopy is also important to reduce the occurrence of residual stones and the rate of reoperation.展开更多
