Objective To evaluate the safety, feasibility and curative effect of mini-incision ex-ploration of common bile duct. Methods In this study, 290 patients underwent min-incision explora-tion of common bile duct and 120 patients underwent open-incision exploration of common bile duct for bile duct stones and/or gallstones from 2005 to 2007. The iatrogenic bile duct injury, postoperative complication, residual stone, stone recurrence,therapeutic effect and clinical data were evaluated by randomized contrast analysis. Results Time of operation, bleeding, volume of drain pipe, time of re-covery of intestinal peristalsis and average duration in hospital were significantly lower in the group of min-incision exploration(MCE) than in the group of open-incision exploration(OCE). The iatrogentic bile duct injury occurred in 5 cases(1.72%), residual stone in 10 cases(3.45%), stone recurrence in 15 cases(5.18%) in the group of MCE, and in 2 cases(1.67%), 4 cases(3. 33%) and 6 cases respec-tively in the group of OCE. There was no marked difference between the two groups. Howevert post-operative complications occurred in 17 cases(6.8%) and 16(13.3%) in the group of MCE and OCE,respectively. There was remarkable difference between the 2 groups(P<0. 05). Conclusion Mini-in-cision exploration of common bile duct is a feasible and safe method resulting in fewer complications of iatrogentic bile duct injury, stone recurrence and residual stone.

Objective To evaluate a modified liver hanging maneuver(retrohepatic tunnel of the IVC) in patients undergoing hemihepatectomy.Methods Twenty-four patients undergoing hemihepatectomy were divided into two groups:modified liver hanging maneuver group(n=12)and Pringle's maneuver group(n=12).The amount of intraoperative bleeding,operation time,postoperative liver function,liver function recovery and complications were compared between the two groups.Reset All operation were performed successfully and there were no difference in the time of operation etween the two groups.There was a difierence in the amount of mean intraoperative blood loss between the two groups.It was(160±40)ml in liver hanging group and(560±120)ml in Pringle's group(P＜0.01).Liver function recovery measured on postoperative day 3 and day 7 was better in liver hanging groupthan that in Pringle's group(P＜0.01).The volume of postoperative peritoneal serous fluid dranage was significantly less in liver hanging group(P＜0.01).Conclusion The modified liver hanging maneuver is useful for hemihepatectomy.

Objective To compare the advantages and disadvantages between laparoscopic operation and laparotomy in the treatment of Mirizzi syndrome.MethodsThe clinical data of 67 cases with Mirizzi syndrome were analyzed retrospectively from January 2008 to June 2011.Thirty-five cases were treated with laparoscopic operation(laparoscopic operation group),type Ⅰ in 24 cases,type Ⅱ in 11 cases,3 cases with conversion to laparotomy were rejected (type Ⅱ in 8 cases really).Thirty-five cases were treated with laparotomy(laparotomy group),type Ⅰ in 20 cases,type Ⅱ in 15 cases.The operation time,blood loss duringoperation,intake time of food,postoperative complications and hospital stay were compared between two groups.ResultsThe operation time was (53.2 ± 21.5) min,blood loss during operation was (23.2 ± 21.5)ml,intake time of food was 6 h,postoperative complications were with 3 cases (9.4％,3/32),hospital stay was(5.4 ±2.3) d in laparoscopic operation group.The operation time was(98.7 ± 17.2) min,blood loss during operation was ( 113.4 ± 31.6) ml,intake time of food was (46.8 ± 12.4) h,postoperative complications were with 5 cases( 14.3％,5/35 ),hospital stay was ( 11.3 ± 2.7) d in laparotomy group.Except for postoperative complications,there were significant differences in the operation time,blood loss during operation,intake time of food and hospital stay between two groups(P＜0.05).ConclusionsLaparoscopic operation is safe and feasible in treating type Ⅰ and most type Ⅱ Mirizzi syndrome.It has more advantages than laparotomy.

Objective To evaluate the impact of pancreatic duct hanging and continuous suturing maneuver in end-to-side pancreaticojejunostomy on the incidence of pancreatic fistula after pancreaticoduodenectomy (PD),and to study the feasibility,safety and efficacy.Method 165 patients who underwent pancreaticoduodenectomy were randomly selected and the incidences of pancreatic fistula for the different types of pancreaticojejunostomy were analyzed.Results The overall rate of pancreatic fistula was 13.9％ (23/165).The incidences of pancreatic fistula after pancreatic duct hanging and continuous suturing maneuver in end-to-side anastomosis (3.1％,2/65,group C) was significantly lower than the traditional intussusception anastomosis (23.1％,12/52,group A,P＜0.05) and the mucosa mucosa anastomosis (18.8％,9/48,group B).There was no significant difference between the traditional intussusception anastomosis and the mucosa mucosa anastomosis (P＞0.05).In group C,the average operative time,intraoperative blood loss,and postoperative drainage was obviously superior to the A and B group (P＜0.05).There was no significant difference between the A and B group (P＞0.05).The other complications showed no significant differences among the three groups (P＞0.05).Conclusion Pancreatic-duct hanging and continuous suturing maneuver in end-to-side anastomosis significantly reduced the rate of pancreatic fistula after pancreaticoduedenectomy.It was feasible,safe,convenient to use and should be popularized.

Objective To investigate laparoscopic-guided selective portal vein ligation in the two-stage hepatectomy for patients with primary hepatocellular carcinoma (HCC).Methods Twenty-three patients with HCC who were not suitable for one-stage hepatectomy were admitted to the Sichuan Provincial People's Hospital from March 2009 to February 2012.Their clinical data were retrospectively analyzed.Laparoscopic-guided selective portal vein ligation was firstly performed,dynamic changes of hepatic volume and predicted volume of liver to be resected were detected by computed tomography.Two-stage open hepatectomy was performed after assessment of resectability of HCC.All data were analyzed using the analysis of variance or q test.Results Laparoscopic-guided selective portal vein ligation was successfully performed on 22 patients (2 patients received concomitant cholecystectomy because the right branch of portal vein was difficult to expose),1 patient was converted to open surgery because of hemorrhage during portal vein separation.Three patients with multiple lesions received transcatheter arterial chemoembolization at 1 week after selective portal vein ligation.Dull pain in the hepatic region,low fever,nausea and vomiting were observed in the 23 patients,while no severe complications including peritoneal hemorrhage,bile leakage,hepatapostema was observed.The levels of aspartate aminotransferase,alanine aminotransferase and total bilirubin were back to normal at 1 week after the surgery.The right liver volume at postoperative week 3 was (590 ± 154)cm3,which was significantly smaller than (698 ± 135)cm3 before surgery.Compared with right liver volume at postoperative week 1,2,3,the right liver volume before operation was significantly smaller (F=15.62,P ＜0.05).The left hepatic volume at postoperative week 3 was (408 ± 149)cm3,which was significantly bigger than (331 ± 68)cm3 before operation.The left liver volume before operation was significantly different from those at postoperative week 1,2,3 (F =17.48,P ＜ 0.05).The predicted ratio of liver to be resected was 60％ ± 18％ at postoperative week 3,which was significantly smaller than 67％ ± 15％ before operation (F =12.35,P ＜ 0.05).Two patients with insufficient hyperplasia of offside liver,2 patients with intrahepatic metastasis at postoperative week 3,2 patients were lost to follow up and 3 patients gave up hepatectomy,14 patients received hepatectomy at 2-4 weeks after laparoscopic-guided selective portal vein ligation.The resection rate was 60.9％ (14/23).There were 2 patients received extended right hepatectomy,8 received right hepatectomy,4 received non-anatomical hepatectomy.All the 14 patients recovered well,and no hepatic failure,severe peritoneal effusion and infection was observed.Conclusion Laparoscopic-guided selective portal vein ligation is easy to perform,and it extends the indication of hepatectomy,increases the safety of two-stage hepatectomy.

Objective To explore the short-term and long-term efficacy of laparoscopic versus open liver resection(LLR)in the treatment of hepatocellular carcinoma(HCC). Methods The perioperative and follow-up data ofLLR(n = 43)and OLR(n = 73)for the treatment of HCC at the same period were analyzed respectively. Results There were no significant differences in the age,gender,Child-Pugh classification,liver cirrhosis, AFP,and hepatic virus affection between the 2 groups. 1 case in the LLR group was converted for the open surgery and another one case in the OLR group died in the perioperative time. However ,compared with OLR group ,the intraoperative blood loss of LLR group(P < 0.05)was larger and the mean operative time(P < 0.05)was longer. The liver function indicators of the regular hepatectomy subgroup were recovered more quickly(P<0.05),but the indicators of remaining subgroups were not significantly different. The postoperative ambulation time (P < 0.05), the postoperative eating time(P < 0.05),the postoperative hospital stay(P < 0.05)were all shorter. The VAS score was lower(P<0.05). There was no difference in the incidence and distribution of complications and the inci-dence of severe complications between the two groups(all P>0.05). The first and third year disease-free survival rates were 82.2%,53.8%for LLR and 91.5%,75.9%for OLR,respectively(χ2=0.55,P=0.46). The first and third 5 year overall survival rates were 94.2%,79.3%for LLR and 94.9%,47.3%for OLR,respectively(χ2=1.06, P=0.30). Conclusion LLR for HCC treatment is a safe and effective way with the advantages of minimal opera-tive trauma,quick recovery and significant short-term efficacy.
