Objective To evaluate the feasibility and clinical efficacy of laparoscopic biliary reoperation. Methods From May 2000 to May 2007, 105 patients received laparoscopic biliary reoperation, including choledocholithotomy and T-tube drainage in 96 cases, Roux-en-Y anastomosis of the gallstone/hepatic-duct in 5, and liver resection in 4. Results The operations were completed in all the 105 patients without severe complications. The operation time was 60-185 min [mean, (125.3?23.2) min]. Intraoperative blood loss was 15-310 ml [mean, (21.1?8.6) ml]. The patients stayed at hospital for 5-9 days after the operation. The 5 patients, who underwent Roux-en-Y anastomosis of the gallstone/hepatic-duct, were followed up for 6 to 65 months [mean, (13.2?8.6)months]. Partial liver resection was performed in 2 cases (resection of the left hepatic lobe in 2, and the right lobe in 2); they were followed up for 8-25 months [mean, (10.2?3.6)months]. In the 96 patients, who received laparoscopic choledocholithotomy and T-tube drainage, the follow-up were lasted for 3-72 months [mean, (13.2?9.6)months]. None of the patients who were followed up had recurrence of gallbladder stone. Conclusions Laparoscopic biliary reoperation is feasible and safe with minimal trauma to patients.

Objective To explore the feasibility and the clinical effect of laparoscopic treatment of incomplete small intestinal obstruction.Methods Eighty-five patients with intestinal obstruction from January 2011 to January 2016 were analyzed retrospectively.Five cases caused by adhesion band were released by laparoscopic cut of the adhesion band.Seventy-five cases were caused by adhesion between intestine, abdominal wall, and pelvic cavity were given laparoscopic adhesion and angle separation.Laparoscopic exploration found appendicitis in 3 cases and a laparoscopic appendectomy was carried out.Two cases were given laparoscopic removal of foreign body inside the intestine.For patients with obvious abdominal distention, an indwelling ileus tube was placed in the intestine before the operation.Results All the laparoscopic surgeries were successfully performed except 2 patients required an additional small incision to perform partial enterectomy and intestinal anastomosis due to intensive local adhesion.No complications happened.Postoperative follow-ups for 3-60 months (mean, 35 months) found no recurrence.ConclusionsLaparoscopic treatment of small intestinal obstruction is feasible and minimally invasive, having advantages of small incision, rapid recovery and short hospitalization.It avoids the trauma caused by open operation.

Objective To explore the feasibility of laparoscopic subtotal colectomy on the basis of lesion identification with the combined use of laparoscopy and fibrocolonoscopy.Methods The operation was carried out under general anesthesia.The patients were maintained at a supine position.Four 10 mm trocars were introduced at the upper and lower borders of the umbilicus,and the left and right lower quadrants of the abdomen,respectively,and a 5 mm trocar was introduced at the right upper quadrant of the abdomen.The laparoscope was placed at the hypogastrium when performing right hemicolectomy,and at the left lower abdomen when left hemicolectomy.During the operation,a fibrocolonoscope was inserted by way of the severed end of the right colon for lesion identification.The colon was disconnected from the cecum to the sigmoid colon.Then the incision at the left lower abdomen was extended to 4 cm in length,and an extracorporeal ileosigmoidostomy was conducted. Results Pathologic changes of thickening and hardening intestinal walls were clearly observed under laparoscope.Fibrocolonoscopic examinations revealed that the false polyps and ulcers on the colonic mucosa had involved the descending colon and the part of the sigmoid colon.The operation time was 170 min and 190 min,respectively,and the intraoperative blood loss was 150 ml and 200 ml,respectively.Pathological examinations after the operation verified the presence of intestinal tuberculosis.No short-term complications occurred after the operation.The frequency of defecation was 5~6 times daily at short-term postoperative period and 1~2 times daily at 5~6 months after the operation.The patients' body weight increased by 2.5 kg and 4 kg,respectively. Conclusions Combined use of laparoscopy and fibrocolonoscopy can accurately evaluate the affected extent of the lesion.Laparoscopic subtotal colectomy is safe and feasible.

Objective To evaluate the feasibility of laparoscopic cholangiotomy for radical excision of upper cholangiocarcinoma. Methods Four trocars were placed at the umbilical area, right upper and lower abdomen, and below the xiphoid. A 3 cm incision was made at the left upper abdomen for Roux-en-Y jejunojejunostomy. The gallbladder, inferior segment of the left medial liver, and the middle-upper segment of the bile duct were resected. And then the tumor and the adjacent 1 cm bile duct were excised. Afterwards, the proper hepatic artery, portal vein, and the surrounding connective tissues and lymph nodes were removed. Finally, the bile-jejunum Roux-en-Y anastomosis was performed. Results The hepatic duct bifurcation was involved by the cholangiocarcinoma in all the 4 cases. The diameter of the tumor was 1-1.5 cm. The resection of the inferior segment of the left medial liver and middle and upper segments of the bile duct, and dissection of the lymph nodes at the hepatic porta were completed successfully. The operation was accomplished in all the cases with an operation time of 270, 255, 270, and 230 mins, and the intraoperative blood loss was 500, 400, 300, and 400 ml, respectively. Postoperative pathological examination showed highly differentiated adenocarcinoma in all the cases. Cases 2 and 3 developed bile leakage after the operation and were cured 20 or 15 days later. In all the cases, the jaundice disappeared after the operation. Their appetite recovered, and the body weight was increased by 3, 3.5, 2, and 2 kg, respectively. Conclusions Upper cholangiocarcinoma can be radically excised by using laparoscopy. The resection of cholangiocarcinoma and part of liver tissues, dissection of surrounding connective tissues and lymph nodes, and bile duct reconstruction can be accomplished under a laparoscope. Thus,we consider that laparoscopic cholangiotomy is feasible for radical excision of upper cholangiocarcinoma.

Objective To explore the feasibitity of endoscopic thyroidectomy through armpit or breast approach. Methods 14 patients aged from 21 to 36 years.There were 11 cases of thyroid adenoma(9 cases of single side and 2 cases of double sides)and 3 cases of nodular goiter (1 case of single side and 2 cases of double sides).The mini-mcision was made at armpit or breast.A percutaneous chennel into thyroid gland was performed and the focus was removed with ultrasonic scalpel wnder endoscopy. Results All cases were operated on under endoscopy,in cluding 11 cases through armpit approach and 3 ones through breast approach.The mean operative time was 135(105～335)min.The average blood loss was 65ml through armpit approach and 135ml through breast approach respectively.There was no operative complications. Conclusions Thyroidectomy under endoscopy is a new secure method.

Objective To summarize our experience in the management of stones impacted at cystic duct during laparoscopic cholecystectomy(LC). Methods There were 58 patients with stones impacted at cystic duct during LC from July 1997 to June 2001.Cystic duct was incised to remove stones first,then intraoperative cholangiography was performed.If stones were found in common bile duct,they would be taken out by intraoperative endoscopic sphincterotomy or open operation. Results All the impacted stones in 58 patients were removed successfully.51 coses underwent LC.Intraoperative cholangiography showed there were common bile duct stones in 7 cases.For these 7 coses,5 cases were treated by LC combined with intraoperative endoscopic sphincterotomy and other 2 cases were converted into open operation.No Severe complication occurred. Conclusions Nearly all cases with stones impacted at cystic duct can receive LC by removing impacted stones through incising the cystic duct and intraoperative cholangiography.If there are any stones in common bile duct,they can be removed by endoscopic sphincterotomy.

Objective To study the feasibility of the ultrasonic scalpel in the management of cystic blood vessels during laparoscopic cholecystectomy(LC). Methods Abdominal blood vessels of two dogs were managed by ultrasonic scalpel under the conditions of two step output power,low tension,low holding force and blunt scalpel head.The blood vessels were sealed and arteries and veins of (1～11)mm were cut.On this basis,the technique was applied to the management of cystic vessels during laparoscopic cystic and biliary operation. Results The sealing and cutting effect was good for the blood vessels of less than 9mm 140/150(93 3%).No blood oozing was found at the cutting ends of blood vessels during and after operation.In all 706 cases of laparoscopic gallbladder and biliary duct operations,no bleeding was found at the cutting ends of blood vessels during and after operation. Conclusions Ultrasonic scalpel can be directly used to seal and cut cystic artery during laparoscopic cholecystectomy.

Objective To explore the feasibility of laparoscopic splenectomy and cholecysterctomy in the treatment of patients with congenital hemolytic anemia and cholecystolithiasis. Methods 8 patients with congenital hemolytic anemia and cholecystolithiasis were operated on by single-stage splenectomy and cholecysterctomy. Results The procedures were successfully accomplished in all patients. The average hospitalization was 7.5 days. No intraoperative and postoperative complications occurred in all of the 8 patients. Conclusions Single-stage laparoscopic splenectomy and cholecysterctomy is the therapy of choice for patients with congenital hemolytic anemia and cholecystolithiasis. The kind of operation is a minimally invasive approach and has the advantages of less injury and short hospital stay.

Objective To explore the feasibility of laparoscope combined with cholangioscope in the management of bile duct calculus. Methods 100 cases of extra- and/or intrahepatic bile duct underwent laparoscopic choledocholithotomy and T-tube drainage or intra- or postoperative cholangioscope was performed from July 1997 to December 2000. Results 42 out of 100 cases obtained intraoperative complete clearance of the bile duct calculus and other 58 cases achieved thorough clearance of calculus postoperatively once to six times. No residual calculus was found in 3 years of follow-up. Conclusions Laparoscopic and cholangioscopic surgery is an effective method for the treatment of bile duct calculus.

Objective To summarize the experience on the prevention of severe complications of endoscopic thyroidectomy.Methods Twelve cases of bilateral lesions underwent endoscopic thyroidectomy via precordial approach and 41 cases of unilateral lesions, via subaxillary approach. A subcutaneous channel, with a width of about 5 cm from the incision site to the thyroid, was made by using self-made instruments. The CO 2 pressure was set at 4 mm Hg. By ultrasonic scalpel the lesions were divided and removed. Results There were 41 cases of thyroid adenoma (unilateral, 34 cases; bilateral, 7 cases) and 12 cases of nodular goiter (unilateral, 7 cases; bilateral, 5 cases). Postoperative subcutaneous hematoma occurred in 1 case and was cured by conservative management. No nerve damage or parathyroid complications were observed. Conclusions Application of ultrasonic scalpel and continued low cavity pressure are effective means for preventing complications in endoscopic thyroidectomy.
