From the March of 1993 to the May of 1994, we had performed laparoscopic cholecystectomy (LC) for 200 patients of the age ranged 19-77 years. In these cases, 12 had previous abdominal surgery; 3 cases had hepatic cysts; 11 cases had stones in the neck of gall bladders. We had successfully performed LC for 190 cases (95%). But we also had some unsuccesful experiences, including accidental injury to the stomach or duodenum, and bleeding from cystic arteris of the gallbladder. Operation (LC) was abandoned in one patient because of severe cardiac arrhyshmia developed during operation, and billiary tract injury was found postoperatively in three patients with no postoperative death. The operative indications and technical problems of LC are discussed in detail and measures in avoiding injury to billiary or GI tract from LC are introduced.

ObjectiveTo analyze the factors influencing the total number of harvested lymph nodes in laparoscopic radical gastrectomy for advanced gastric cancer.MethodsThe clinicopathologic data of patients who underwent laparoscopic D2 radical resection of gastric cancer in this hospital for advanced gastric cancer from January 2018 to July 2020 were retrospectively analyzed. The statistical analysis was conducted to analyze the influence factors (age, gender, tumor size, tumor site, body mass index, infiltration depth, lymph node metastasis, HER-2 gene amplification status, presence or absence of vascular tumor thrombus, presence or absence of nerve infiltration, differentiation type, pTNM, Borrmann type, and type of gastrectomy) on the number of harvested lymph nodes.ResultsA total of 536 patients met the inclusion and exclusion criteria were included. The results of univariate analysis showed that the total number of harvested lymph nodes during laparoscopic radical gastrectomy for advanced gastric cancer was correlated with age, tumor size, tumor infiltration depth, lymph node metastasis, pTNM stage, Borrmann type, and type of gastrectomy. That was, the younger the patient was (≤ 54 years old), the larger the tumor was (long diameter >3.5 cm), the later the Borrmann classification was (type Ⅲ, Ⅳ), the deeper the tumor invasion was, the more the number of lymph node metastasis was, the later the pTNM stage was, and the more the number of lymph nodes was detected in patients undergoing total gastrectomy (all P<0.05). The multiple linear regression analysis showed that the age, lymph node metastasis, and PTNM stage had significant effects on the number of harvested lymph nodes. The multiple linear regression model was statistically significant (F=6.754, P<0.001). 11.2% of the variation in the number of harvested lymph nodes could be explained by the age, lymph node metastasis, and pTNM stage (adjusted R2=11.2%). ConclusionsNumber of harvested lymph nodes in laparoscopic radical gastrectomy for advanced gastric cancer is greatly affected by the age of patients, lymph node metastasis, and pTNM stage. So patients should be evaluated objectively and individually according to their age so as to harvest sufficient number of lymph nodes, which is conducive to accurately judge pTNM stage, formulate accurate adjuvant treatment scheme, and improve prognosis of patients.
Objective To investigate the technique and feasibility of hepatic pedicle vascular control in laparoscopic hepatectomy. Methods From May 2005 to June 2011, 95 cases of hepatectomies were performed by laparoscopy in the Department of Minimally Invasive Surgery, The First Affiliated Hospital, Guangxi Medical University.The characteristics of these cases were analyzed. Results Left lateral segmentectomy were required in 21 patients, left hepatectomy in 13 patients, right hepatectomy in 4 patients, segmentectomy in 17 patients, tumor resection in 24 patients,hemangioma resection in 5 patients, and conversions to laparotomy in 11 patients. The intermittent Pringle maneuver were performed in 39 patients. The mean vascular clamping time in Pringle maneuver was （30.84±9.51） min. The selective vascular control of inflow were performed in 56 patients， the technique included intrahepatic Glisson approach in 14 patients and controlling hepatic artery and portal vein separately in 42 patients. Pre-parenchymal transection control of hepatic outflow were performed in 12 patients, included the left hepatic vein were controlled by suturing or separating in 11 patients and right hepatic vein was controlled by separating in 1 patient. Others were controlled intraparenchymally during transection. The mean operative time was （236.80±95.97） min，mean operative blood loss was（ 551.55±497.41） ml， concentrate red blood cells transfusion volume was（ 2.60±2.23） U， and plasma transfusion volume was （211.90±179.29） ml. The postoperative complications included bleeding in 4 patients, pleural effusion in 4 patients, pneumonia in 3 patients, ascites in 7 patients, and biliary fistula in 2 patients, and dead in 1 patient. The mean hospitalization time was（ 12.47±4.18） days. At the deadline（ February 2012）, 72 cases with liver cancer were followup. The follow-up time ranged from 5 to 81 months and the mean time was（ 24.14±16.62） months， where survival rate was 68.4%（ 54/79） of 1-year and 21.5%（ 17/79） of 3-year. Conclusions The application of hepatic pedicle vascular control in laparoscopic hepatectomy is feasible.
Objective To explore the feasibility and safety of laparoscopic cyst resection and Roux-en-Y hepatojejunostomy in treatment for adult congenital cholangiectasis and to compare the therapeutic effects of laparoscopic procedure with conventional open procedure. Methods The clinical data of 33 adult patients with congenital cholangiectasis from May 2008 to September 2011 in the department of general surgery of Shengjing Hospital of China Medical University were retrospectively analyzed. Fourteen patients received laparoscopic procedure （laparoscopic group），whereas the other 19 patients received conventional open procedure （conventional group）. Results All the operations were carried out successfully through laparoscopic procedure. The mean time of operation in the laparoscopic group was significantly longer than that in the conventional group （195min versus 130min，P＜0.01）. The average intraoperative blood loss in the laparoscopic group was significantly less than that in the conventional group （80ml versus 270ml，P＜0.01）. In contrast，the mean time of bowel peristalsis recovery and postoperative hospital stay in the laparoscopic group were significantly shorter than those in the conventional group （time of bowel motion recovery：76h versus 104 h，P＜0.01；hospital stay：6.1 d versus 9.6 d，P＜0.01）. There were no differences in the early complications between two groups （P＞0.05）. Conclusions Totally laparoscopic treatment for congenital cholangiectasis in adult is feasible and safe. It is worth to be generally applied because of its minimal invasion and fast postoperative recovery.

ObjectiveTo emphasize the important role of video-assisted thoracoscopic surgery (VATS) in treatment of mediastinal bronchogenic cysts (MBCs).MethodsWe retrospectively reviewed the clinical data of 112 patients (53 males and 59 females) of mediastinal bronchogenic cysts who underwent VATS in our institution between April 2001 and Aprial 2016. Median age was 4–75 (45.6±15.0) years. All patients underwent chest CT preoperatively. The patients were divided into two groups: an anterior mediastinum group, 47 patients; a middle and posterior mediastinum group, 65 patients including 35 patients in the middle mediastinum, 30 patients in the posterior mediastinum. The average diameter was 0.5–22.0 (3.50±2.33) cm. The average CT attenuation was 0–67 (35.5±15.3) Hu on unenhanced CT. We began each operation with the VATS technique.ResultsThe CT diagnostic accuracy for group middle and posterior mediastinum with CT value≤20 Hu was higher than others (61.5% vs. 13.1%, χ2=17.675, P<0.001). A total of 111 patients underwent VATS, only one patient converted to open thoracotomy. Cyst resection and thymectomy were conducted in 45 patients, cyst resection and extended thymectomy were conducted in 2 patients in the anterior mediastinum group. Simply cyst resection were performed in the middle and posterior mediastinum group (n=65). The average operative time was 40–360 (104.5±43.1) min. The average intraoperative blood loss was 5–600 (57.9±88.9) mL. The intraoperative complication rate was 3.6% and the incomplete resection rate was 6.3%. The main reason for these was severe adhesion between the cyst and mediastinal structure. No serious postoperative complication was found. Follow-up was done in 99 patients, and the mean follow-up time was 42 (12–191) months. There was no local recurrence.ConclusionVATS resection of MBCs is a safe and efficacious procedure, and minimally invasive and surgical resection should be performed as early as possible for MBCs.
