Objective To explore the operation methods and indications of the transabdominal reverse guided-laparoscopic endoscopic sphincterotomy in treatment of duodenal papilla stenosis during the course of laparoscopic common bile duct exploration.
Methods The clinical data of 501 cases of duodenal papilla stenosis who underwent laparoscopic endoscopic sphincterotomy with the transabdominal reverse guide technique from March 2003 to July 2015 in the Second People’s Hospital of Chengdu city were analyzed retrospectively.
Results All operation of the 501 cases were successful, no death happened. The operation time were 60-190 min (average of 107 min), the blood loss were 5-100 mL (average of 21.8 mL), and postoperative hospitalization time were 4-9 days (average of 6.7 days). It was successful in 501 cases that removed the gallbladder, and successful in 493 cases (98.4%) that removed the common bile duct stones out of 501 cases. Six cases (1.2%) had residual stones in T tube drainage and received treatment with postoperative choledochoscope and electrohydraulic lithotripsy. Two cases (0.4%) of primary suture had residual stones. In the 501 cases, 364 cases (72.7%) underwent directly implementation of primary suture after the success of papillary stenosis cutting, 9 cases (1.8%) underwent primary suture after indwelling ureteral catheter, 118 cases (23.5%) underwent primary suture after detaining nasobiliary drainage, 4 cases (0.8%) failed in cutting the papillary stenosis and 6 cases (1.2%) had residual stones, all the 10 cases turned into the T tube drainage. After the operation, 9 cases (1.8%) suffered from mild pancreatitis and 23 cases (4.6%) suffered from bile leakage, no perforation of intestine and bile duct, bleeding, severe pancreatitis, and other complications happened. The overall incidence of postoperative complication was 6.8% (34/501).
Conclusion If patients are suitable, transabdominal reverse guided-laparoscopic endoscopic sphincterotomy in treatment of duodenal papilla stenosis is safe and effective.
ObjectiveTo evaluate the value of incision closure device in laparoscopic cholecystolithotomy.
MethodsThe clinical data of 130 patients underwent laparoscopic cholecystectomy from Oct. 2014 to Feb. 2015 were retrospectively analyzed. According to the methods of gallbladder suture, 130 cases were divided into two groups, 72 cases underwent traditional manual suture (MS group), and 58 cases underwent incision closure device (ICD group). The operative time, postoperative gastrointestinal function recovery time, bleeding volume, postoperative hospitalization time, hospitalization expenses, complications, and postoperative 6-12 months follow-up of patients in 2 groups were observed.Results One hundred and thirty cases were performed laparoscopic cholecystolithotomy successfully. The operative time and postoperative gastrointestinal function recovery time of ICD group were significantly shorter than those of MS group, the difference was statistically significant (P < 0.05). The hospitalization expenses of the patients in ICD group were significantly higher than those in the MD group (P < 0.05). There were no significant difference between the two groups in the bleeding volume and postoperative hospital stay (P > 0.05). The patients were followed up for 6-12 months, with an average of 8 months, and no complications occurred and stone recurrence.
ConclusionIncision closure device can shorten the time of laparoscopic cholecystolithotomy and postoperative recovery of gastrointestinal function, but the cost is higher. Next development, still need decrease the expend and strengthen clinical promotion.
Objective To investigate the feasibility and safety of laparoscopic operation of gastric and gastroesophageal junction diseases. Methods Between May 2004 and June 2009, 59 patients with gastric and gastroesophageal diseases were treated laparoscopically. The operative methods and maneuvers were evaluated and perioperative interventions, complications and efficacy of patients were analyzed. Results All operations were successfully completed laparoscopically except for one patient with gastric cancer who required a conversion to open surgery. No short-term complications occurred in all cases. No port transplant metastasis occurred for the patients with gastric cancer after an average of 36 months (1-60 months) follow-up. One patient died of liver metastasis 12 months after operation. The 3-year survival rate was 93.3% (14/15). Conclusion Laparoscopic surgery of the gastric and gastroesophageal junction diseases is feasible and safe with minimal invasiveness, which is worth popularizing.
Objective To investigate the feasibility of laparoscopic cholecystectomy through the transumbilical approach. MethodsThe clinical data of 18 patients underwent endoscopic cholecystectomy through only one transumbilical incision at West China Hospital were retrospectively analyzed. Results All of the operations were successfully completed without conversion to routine laparoscopic surgery or open surgery. The operation time was 40-130 （58±10） min. There was no intraoperative complication. The patients did well postoperatively and were discharged 1 day after operation. There was no postoperative complications and without visible abdominal scar on 1 month follow-up. Conclusions Laparoscopic cholecystectomy through the transumbilical approach is technically feasible and safe. But this technique is difficult, the patients should be selected carefully.

Objective To study the clinical value and surgical procedure of laparoscopic operation for interstitial tubal pregnancy. Methods Clinical data of 36 patients of interstitial tubal pregnancy treated by laparoscopic operation were retrospectively analyzed. Results All 36 patients were operated successfully, without conversions to laparotomy and intra- or post- operative complications. The operation time was 28-85 min(mean, 41min), and the length of stay in hospital postoperative was 3-6 d (mean, 4-5 d). Conclusion Laparoscopic operation for interstitial tubal pregnancy is safe and feasible.
Objective To systematically evaluate the efficiency of laparoscopic hepatectomy（LH） and conventionalopen hepatectomy （OH）in patients with hepatocellular carcinoma （HCC）. Methods The literatures about the therap-eutic effect of LH and OH on hepatocellular carcinoma were collected from PubMed， Chinese Journal Full-text Database （CJFD）， Wanfang Database， China Doctor/Master Dissertations Full-text Database （CDMD）， and China Proceedings of Conference Full-text Database （CPCD）from 2000 to 2011. RevMan 5.0 software was used for data analysis. Results Eleven controlled clinical trials were included in this analysis. These studies included a total of 781 patients：325 treated with LH and 456 treated with OH. The results of meta-analysis showed that LH group had shorter operation time〔WMD=-20.85， 95% CI （-29.54， -12.16）， P＜0.000 01〕， less operative blood loss 〔SMD=-0.42，95% CI（-0.65，-0.19）， P=0.000 4〕， a lower postoperative morbidity rate 〔OR=0.43，95% CI （0.28，0.65），P＜0.000 1〕， and shorter hospitalization days 〔WMD=-4.32，95％ CI （-6.29，-2.34），P＜0.000 1〕 than OH group. There was no significant difference in postoperative recurrence （P=0.80）， overall survival in 1-year （P=0.98）， 3-year （P=0.41）， and 5-year （P=0.12）， and in disease-free survival in 1-year （P=0.15）， 3-year （P=0.62）， and 5-year （P=0.99）between the two groups. Conclusions For the patients with hepatocellular carcinoma localized to the CouinaudⅡ，Ⅲ，Ⅳ，Ⅴ，and Ⅵ segments with a maximum lesion size of 5cm， as well as the tumor has no effect on the exposure of blood vessel of the first and second hepatic portal， and the liver functions are classified as Child B or A high grade， the laparoscopic liver resection is priority considered in the conditions allow.
Objective To systematically assess the effectiveness and safety of streamlined liner of the pharynx airway (SLIPA) compared with endotracheal tube (TT) for airway management in patients undergoing laparoscopic cholecystectomy surgery. Methods Databases such as PubMed (1992 to February 2012), EMbase (1984 to February 2012), MEDLINE (Ovid, 1964 to February 2012), SCI (1992 to February 2012), CNKI (1992 to February 2012), CBM (2002 to 2012) as well as WanFang Data (1992 to February 2012) were searched for relevant literature. The references of the included articles were also manually traced. Two reviewers independently screened the trials according to inclusion and exclusion criteria, extracted the data, and assessed the quality of methodology. Meta-analyses were performed using RevMan 5.0 software. Results Ten randomized controlled trials (RCTs) involving 664 patients were included. Results of meta-analysis showed that: a) as for side effects, none of the patients experienced regurgitation or hypoventilation during operation; b) as for extubation response, SLIPA was proved fewer than TT during extubation with a significant difference (RR=0.14, 95%CI 0.05 to 0.36, Plt;0.000 1); c) SLIPA was superior to TT with regard to reducing postoperative sore throat (RR=0.15, 95%CI 0.06 to 0.38, Plt;0.000 1); d) SLIPA was similar to TT with regard to Ppeak after peritoneal insufflations (WMD=–0.07, 95%CI –0.73 to 0.59, P=0.83); e) as for PETCO2, the SLIPA group was lower than the TT group obviously after peritoneal insufflations (WMD=–1.09, 95%CI –1.70 to –0.49, P=0.000 4); f) as for hemodynamic change, the SLIPA group was more stable than the TT group during the operation with significant differences (Plt;0.05). Conclusion Current studies suggest that it is safe and effective to apply SLIPA for ventilation in laparoscopic cholecystectomy surgery. However, due to the limited quantity and quality of the included studies, more high-quality studies are need.
ObjectiveTo investigate the efficacy and safety of laparoscopic surgery for overweight/obese patients with acute perforated or gangrenous appendicitis.
MethodsFrom January 2007 to December 2014, patients with acute perforated or gangrenous appendicitis underwent laparoscopic (152 cases) or open (60 cases) appendectomy were collected, who were retrospectively classified into overweight/obese group (BMI≥25 kg/m2, n=69) or normal weight group (BMI < 25 kg/m2, n=143). Conversion rate, operation time, hospital stay, readmission, reoperation, and postoperative complications such as incision infection, abdominal abscess, and lung infection were analyzed.
Results①The rate of conversion to open surgery had no significant difference between the overweight/obese group and the normal weight group[4.2% (2/48) versus 6.7% (7/104), χ2=0.06, P > 0.05].②The operation time of laparoscopic surgery in the overweight/obese group was significantly shorter than that of the open surgery in the overweight/obese group[(41.6±11.7) min versus (63.1±23.3) min, P < 0.01], which had no significant difference between the laparoscopic surgery in the overweight/obese group and laparoscopic surgery in the normal weight group[(41.6±11.7) min versus (39.6±12.7) min, P > 0.05].③The total complications rate and incision infection rate of the laparoscopic surgery in the overweight/obese group were significantly lower than those of the open surgery in the overweight/obese group[total complications rate:16.7% (8/48) versus 52.4% (11/21), χ2=9.34, P < 0.01; incision infection rate:4.2% (2/48) versus 33.3% (7/21), χ2=8.54, P < 0.01]. Although the total complications rate of all the patients in the overweight/obese group was increased as compared with all the patients in the normal weight group[27.5% (19/69) versus 14.7% (21/143), χ2=5.02, P < 0.01], but which had no significant difference between the laparoscopic surgery in the overweight/obese group and laparoscopic surgery in the normal weight group[16.7% (8/48) versus 12.5% (13/104), χ2=0.45, P > 0.05].④The reoperation rate of all the patients performed laparoscopic surgery was significantly lower than that of all the patients performed open operation[1.3% (2/152) versus 10.0% (6/60), χ2=6.7, P < 0.01].⑤The abdominal abscess rate, lung infection rate, and hospital stay after discharge had no significant differences among all the patients (P > 0.05).
ConclusionLaparoscopic appendectomy could be considered a safe technique for overweight/obese patients with acute perforated or gangrenous appendicitis, which could not increase the difficulty of laparoscopic surgery and the perioperative risk.
ObjectiveTo explore the feasibility and clinical efficacy of laparoscopic sentinel lymph node biopsy combined with endoscopic submucosal dissection(ESD) for patients with early gastric cancer(EGC).
MethodsThe clinical data of 26 cases who received ESD combined with laparoscopic sentinel lymph node biopsy for EGC between March 2009 to August 2013 in Affiliated Hospital of Jiangnan University were analyzed retrospectively. These patients first underwent laparoscopic sentinel lymph node(SLN) biopsy. If frozen sectioning examination suggested there was lymph node metastasis, laparoscopic D2 radical gastrectomy would be operated. However, the ESD would be operated if the frozen sectioning examination was negative.
ResultsThe total numbers of SLN were 95, and mean numbers of SLN were 3.7±1.4(range from 1 to 6). Two patients with positive SLN underwent laparoscopic-assisted distal gastrectomy and 24 patients with negative SLN underwent ESD. The disease free survival(DFS) and local recurrence rate after ESD for EGC was 91.7%(22/24) and 4.2%(1/24), respectively. And the total DFS for all patients was 96.2% (25/26).
ConclusionESD for EGC is a safe and feasible procedure, combined with laparoscopic sentinel lymph node biopsy conforms more to the concept of principle of radical operation.
