Objective To study the change of common bile duct pressure after laparoscopic common bile duct exploration in patients with common bile duct stones.Methods Clinical data of 17 patients with common bile duct stones treated in our hospital from January 2022 to December 2022 were collected.All patients underwent laparoscopic common bile duct exploration and common bile duct pressure measurement.The patients were followed up for 8 weeks after operation,and the common bile duct pressure was measured by indwelling T tube at 2,3,4 and 8 weeks.Results Among the 17 patients,1 patient showed persistent high common bile duct pressure due to residual common bile duct stones.In the remaining 16 patients,there were no significant difference between the initial common bile duct pressure(19.7 cm H2O)and the common bile duct pressure at postoperative(17.0 cm H2O)and week 1(15.5cmH2O)(P＞0.05).There were significant differences between the initial common bile duct pressure and the common bile duct pressure at week 2(13.5 cm H2O),3(12.2 cm H2O),4(11.1 cm H2O)and 8(10.0cmH2O)(P＜0.05).Conclusion Compared to initial common bile duct pressure,the pressure of common bile duct began to decrease significantly from 2 weeks after laparoscopic common bile duct exploration in patients with common bile duct stones.

Objective:To investigate the application value of Da Vinci robotic surgical system in radical resection of perihilar cholangiocarcinoma (pCCA).Methods:The retrospective and descrip-tive study was conducted. The clinicopathological data of 10 patients undergoing Da Vinci robotic radical resetion of pCCA in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from September 2018 to March 2021 were collected. There were 6 males and 4 females, aged (58±7)years. Observtaion indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. The patients were followed up by telephone interview and outpatient service to detect survival of patients and tumor recurrence up to June 2021. Measurement data with normal distribution were expressed as Mean± SD, and measurement data with skewed distribu-tion were represented as M(range). Count data were represented as absolute numbers. Results:(1) Surgical situations: 10 patients underwent Da Vinci robotic radical resection of pCCA succe-ssfully, without conversion to laparotomy or intraoperative blood transfusion. The operation time of 10 patients was (465±87)minutes, and the volume of intraoperative blood loss was (167±81)mL. Of the 10 patients, 1 case of Bismuth type Ⅲb had a positive surgical margin and the remaining 9 cases had R 0 resection. (2) Postoperative situations: the time to gastric tube extraction was (2.3±1.9)days, and the duration of postoperative hospital stay of the 10 patients was (19.9±9.0)days. Among the 10 patients, there was no second operation or perioperative death. Of the 10 patients, 6 cases had perioperative complications, including 5 cases wth pleural effusion, 3 cases with peritoneal effusion, and 1 case with intestinal obstruction, some patients had multiple complications. After symptomatic conservative treatment, pleural effusion and peritoneal effusion disappeared and intestinal obstruction was improved. None of the 10 patients had serious complica-tions such as bleeding, biliary fistula or intestinal fistula. (3) Follow-up: 10 patients were followed up for 3-20 months, with a median follow-up time of 11 months. During the follow-up, 3 of 10 patients had tumor recurrence which occurred in intrahepatic bile duct of residual liver, and no implantation metastasis was found in the rest of abdominal cavity. Of the 7 unrecurrent patients, 1 case died of gastrointestinal bleeding and multiple organ failure. Nine of 10 patients survived well. Conclusion:The Da Vinci robotic surgical system used for radical operation of pCCA is feasible.

Objective To explore the clinical efficacy of the gap above the splenic pedicle in laparoscopic splenectomy (LS).Methods The retrospective cohort study was conducted.The clinical data of 189 patients who underwent LS in the Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology between August 2012 and March 2015 were collected.Among 189 patients receiving splenic pedicle division,42 without the application of the gap above the splenic pedicle were allocated into the group A and 147 with the application of the gap above the splenic pedicle were allocated into the group B.Observation indicators included:(1) operation situations:combined operation,operation time (excluding combined operation time),volume of intraoperative blood loss (excluding blood volume of spleen),cases with conversion to open surgery;(2) postoperative situations:time to initial anal exsufflation,time for fluid diet intake,occurrence of postoperative complications and duration of hospital stay;(3) follow-up.Patients were followed up by telephone interview and outpatient examination up to August 2016.Follow-up included routine blood test,coagulation function,liver function,with or without long-term complications.Measurement data with normal distribution were represented as x±s and comparison between groups was analyzed using the t test.Comparisons of count data were analyzed by the chi-square test.Results (1) Operation situations:of 189 patients undergoing LS,136 combined with laparoscopic pericardial devascularization,13 combined with laparoscopic cholecys-tectomy,9 combined with laparoscopic radio frequency ablation (RFA) of liver tumors and 26 combined with pathological examination using laparoscopic liver tissues sampling.Operation time,volume of intraoperative blood loss and cases with conversion to open surgery were (118±31) minutes,(80±38) mL,2 in the group A and (70± 22) minutes,(50± 28) mL,1 in the group B,respectively,with statistically significant differences between the 2 groups (t =12.579,-8.516,x2=4.912,P＜0.05).(2) Postoperative situations:time to initial anal exsufflation,time for fluid diet intake,number of patients with postoperative complications and duration of hospital stay were (22± 10)hours,(3.1 ± 1.3) days,8,(9±3)days in the group A and (23±11)hours,(3.8±1.8)days,13,(8±3)days in the group B,respectively.Pancreatic fistula,intra-abdominal hemorrhage,asymptomatic portal vein thrombosis,pulmonary infection and intraperitoneal infection were respectively detected in 2,2,2,1,1 patients in the group A and 1,2,5,2,3 patients in the group B.There was no significant difference in time to initial anal exsufflation,time for fluid diet intake and duration of hospital stay between the 2 groups (t =1.102,0.745,0.583,P＞0.05),and a statistically significant difference in number of patients with postoperative complications between the 2 groups (x2 =7.259,P＜ 0.05).There were statistically significant differences in cases with pancreatic fistula and intra abdominal hemorrhage (x2=16.021,5.812,P＜0.05) and no significant difference in cases with asymptomatic portal vein thrombosis,pulmonary infection and intraperitoneal infection (x2 =1.391,0.396,0.865,P＞0.05).Patients with postoperative complications were cured by symptomatic treatment.(3) Follow-up:156 of 189 patients (33 in the group A and 123 in the group B) were followed up for 1-18 months,with an average time of 12 months.During the follow-up,13 patients had recurrent hematemesis and melena,including 3 in the group A and 10 in the group B.Eight patients stopped bleeding after conservative treatment,3 stopped bleeding after proxial gastrectomy and 2 died of excessive bleeding and organ failure.Conclusion Splenic pedicle division using Endo-GIA through the gap above the splenic pedicle in LS can reduce operation time,volume of intraoperative blood loss,rate of conversion to open surgery and postoperative complications.

Objective To investigate the operational technique of laparoscopic splenectomy and pericardial devascularization (LSPD) and evaluate the clinical efficiency of this method for the treatment of portal hypertension.Methods With the new understanding of anatomical space around the spleen,the cardia and the fundus,two gaps and two tunnels can be created in LSPD.Retrospective analysis was made on the clinical data of patients who underwent LSPD from Jun 2013 to Mar 2015.The operative time,intraoperative blood loss,postoperative hospital stay,conversion rate and postoperative complication rate were measured.Results A total of 189 cases underwent surgery successfully,including 34 cases of splenomegaly and 21 cases of severe esophageal varices.The operative time was (125 ± 52) min,intraoperative blood loss (58 ± 32) ml,postoperative hospital stay (7.5-2.1) d.There were 4 conversion cases in this study.Conclusions The splenic pedicle and stomach pedicle can be safely dissected with the two gaps and two tunnels principle,which makes LSPD safe and convenient.
