Objective To evaluate the safety and effectiveness of laparoscopic common bile duct exploration in the treatment of common bile duct stones. Methods A retrospective analysis was conducted for 158 patients with cholecystolithiasis and choledocholithiasis admitted to the Number One Hospital of Zhangjiakou from January 2015 to December 2019.The patients were assigned into three groups according to the diameters of cystic duct and common bile duct,degrees of abdominal infection and tissue edema,and operation method.Group A(16 cases):laparoscopic cholecystectomy,transcystic choledochoscopic exploration for stone removal;Group B(94 cases):laparoscopic cholecystectomy,common bile duct incision exploration combined with choledochoscopy for stone removal,T tube drainage;Group C(48 cases):laparoscopic cholecystectomy,common bile duct incision exploration combined with choledochoscopy for stone removal,primary closure of the common bile duct.The operation time,residual rate of stones,and complication(bleeding,bile leakage,and wound infection) rate were compared between groups. Results The operation time of groups A,B,and C was(95.1±14.7),(102.2±18.1),(110.1±16.4) minutes,respectively,which showed no statistical difference between each other(F=0.020,P=0.887).One case in group A had residual stones,while no residual stone appeared in groups B and C.The overall stone clearance rate was 99.4% and the overall complication rate was 1.9%.There was no perioperative death. Conclusion It is generally safe and effective to carry out laparoscopic cholecystectomy and common bile duct exploration for stone removal in suitable populations.

OBJECTIVE: To explore the feasibility and efficacy of laparoscopic transcystic drainage and common bile duct exploration in the treatment of patients with difficult biliary stones. METHODS: Between April 2020 and December 2021, eighteen patients with difficult biliary stones received laparoscopic transcystic drainage (C-tube technique) and common bile duct exploration. The clinical characteristics and outcomes were retrospectively collected. The safety and effectiveness of laparoscopic transcystic drainage and common bile duct exploration were analyzed. RESULTS: Among the eighteen patients with difficult biliary stones, thirteen patients received traditional laparoscopic transcystic drainage, and the remaining five received modified laparoscopic transcystic drainage. The mean surgical duration were (161±59) min (82-279 min), no bile duct stenosis or residual stone was observed in the patients receiving postoperative cholangiography via C-tube. The maximum volume of C-tube drainage was (500±163) mL/d (180-820 mL/d). Excluding three patients with early dislodgement of C-tube, among the fifteen patients with C-tube maintained, the median time of C-tube removal was 8 d (5-12 d). The duration of hospital stay was (12±3) d (7-21 d) for the 18 patients. Five C-tube related adverse events were observed, all of which occurred in the patients with traditional laparoscopic transcystic drainage, including two abnormal position of the C-tube, and three early dislocation of the C-tube. All the 5 adverse events caused no complications. Only one grade one complication occurred, which was in a patient with modified laparoscopic transcystic drainage. The patient demonstrated transient fever after C-tube removal, but there was no bile in the drainage tube and the subsequent CT examination confirmed no bile leakage. The fever spontaneously relieved with conservative observation, and the patient recovered uneventfully with discharge the next day. All the 18 patients were followed up for 1-20 months (median: 9 months). Normal liver function and no recurrence of stone were detected with ultrasonography or magnetic resonance cholangiopancreatography (MRCP). CONCLUSION Laparoscopic transcystic drainage combined with common bile duct exploration is safe and feasible in the treatment of patients with difficult biliary stones. The short-term effect is good. Modified laparoscopic transcystic drainage approach may reduce the incidence of C-tube dislocation and bile leak.

OBJECTIVE: To distinguish the endoscopic and clinical features of ampullary polyps, to investigate the endoscopic cancer risk factors of ampullary polyps based on the compared differences of benign lesions and adenocarcinoma, and to assess the accuracy of forceps biopsy. METHODS: Authors retrospectively analyzed the data extracted from patients treated with endoscopic papillectomy (EP) from January 2009 to May 2019 in the Department of Gastroenterology, Peking University Third Hospital. Endoscopic pictures and pathology reports were reevaluated and analyzed. Differences between benign and cancer groups were conducted. RESULTS: In the study, 42 cases were involved, 35 to 83 years old, containing 83.3% older than 50 years old patients. The histological types were as follows, 2 for inflammatory polyps (4.8%), 1 for neuroendocrine tumor (2.4%), 1 for hyperplastic polyp (2.4%), 5 for grade Ⅰ adenoma (11.9%), 10 for grade Ⅱ adenoma (23.8%), 4 for grade Ⅲ adenoma (9.5%) and 19 for adenocarcinoma (45.2%), and 90.5% were adenoma or adenocarcinoma. The average age of benign group (inflammatory polyps and adenomas) was (56.7±9.2), which was significantly younger than that of adenocarcinoma group [(66.0±9.8), P=0.004]. Tumor diameter in adenocarcinoma group[(2.3±0.8) cm] was significantly larger than that in benign group[(1.6±0.6) cm, P=0.002]. Benign lesions only showed Yamada type Ⅰ(57.1%)and type Ⅱ(42.9%). The percentage of Yamada type Ⅰ (36.8%)and type Ⅱ(31.6%) in adenocarcinoma group was lower than that in benign group. Moreover, Yamada type Ⅲ (31.5%) was only found in the adenocarcinoma group. Significant differences were observed between the two groups in Yamada types (P=0.046). Most of the benign lesions had clear boundary(18/21, 85.7%). The percentage of clear boundary in adenocarcinoma group (2/19, 10.5%) was significantly lower than that in the benign group (P < 0.001). No significant differences were investigated in color (P=0.353) and surface (P=0.324) between benign and adenocarcinoma lesions. Pooling age, lesion diameter, Yamada type and clear boundary into Logistic regression analysis, only age (OR=1.186, 95%CI 1.025-1.373, P=0.022) and clear boundary (OR=66.218, 95%CI 3.421-1 281.840, P=0.006) were the independent cancer risk factors. Only 2 (10.5%) in the 19 cancer patients had positive biopsy results before EP. As compared with post-EP, 55.3% (21/38) biopsies were under-estimated, including 17 (17/19, 89.5%) adenocarcinomas and 4 (4/10, 40%) grade Ⅱ adenomas. CONCLUSION adenoma and adenocarcinoma were the major histological type of ampullary po-lyps. Age and unclear boundary were the independent risk factors of ampullary adenocarcinoma. Forceps biopsy was not enough for ampullary polyp differentiation.

PURPOSE: Donor safety is the most important problem of living donor liver transplantation (LDLT). Although laparoscopic liver resection has gained popularity with increased surgical experience and the development of laparoscopes and specialized instruments, a totally laparoscopic living donor right hepatectomy (LDRH) technique has not been investigated for efficacy and feasibility. We describe the experiences and outcomes associated with LDRH in adult-to-adult LDLT in order to assess the safety of the totally laparoscopic technique in donors. METHODS: Between May 2016 and July 2017, we performed hepatectomies in 22 living donors using a totally laparoscopic approach. Among them, 20 donors underwent LDRH. We retrospectively reviewed the medical records to ascertain donor safety and the reproducibility of LDRH; intra-operative and post-operative results including complications were demonstrated after performing LDRH. RESULTS: The median donor age was 29 years old and the median body mass index was 22.6 kg/m2. The actual graft weight was 710 g and graft weight/body weight (GRWR) was 1.125. No donors required blood transfusion, conversion to open surgery, or reoperation. The postoperative mortality was nil and postoperative complications were identified in two donors. One had fluid collection in the supra-pubic incision site for graft retrieval and the second had a minor bile leakage from the cutting edge of the right hepatic duct stump. All the liver function tests returned to normal ranges within one month. CONCLUSION: LDRH is a feasible operation owing to low blood loss and few complications. However, LDRH can be initially attempted after attaining sufficient experience in laparoscopic hepatectomy and LDLT techniques.

PURPOSE: Cholecystectomy in patients with an intact gallbladder after endoscopic removal of stones from the common bile duct (CBD) remains controversial. We conducted a case-control study to determine the risk of recurrent CBD stones and the benefit of cholecystectomy for prevention of recurrence after endoscopic removal of stones from the CBD in Korean patients. MATERIALS AND METHODS: A total of 317 patients who underwent endoscopic CBD stone extraction between 2006 and 2012 were included. Possible risk factors for the recurrence of CBD stones including previous cholecystectomy history, bile duct diameter, stone size, number of stones, stone composition, and the presence of a periampullary diverticulum were analyzed. RESULTS: The mean duration of follow-up after CBD stone extraction was 25.4+/-22.0 months. A CBD diameter of 15 mm or larger [odds ratio (OR), 1.930; 95% confidence interval (CI), 1.098 to 3.391; p=0.022] and the presence of a periampullary diverticulum (OR, 1.859; 95% CI, 1.014 to 3.408; p=0.045) were independent predictive factors for CBD stone recurrence. Seventeen patients (26.6%) in the recurrence group underwent elective cholecystectomy soon after endoscopic extraction of CBD stones, compared to 88 (34.8%) in the non-recurrence group; the difference was not statistically significant (p=0.212). CONCLUSION: A CBD diameter of 15 mm or larger and the presence of a periampullary diverticulum were found to be potential predictive factors for recurrence after endoscopic extraction of CBD stones. Elective cholecystectomy after clearance of CBD stones did not reduce the incidence of recurrent CBD stones in Korean patients.

BACKGROUNDLaparoscopic cholecystectomy (LC) has been a standard operation and replaced the open cholecystectomy (OC) rapidly because the technique resulted in less pain, smaller incision, and faster recovery. This study was to evaluate the value of blunt dissection in preventing bile duct injury (BDI) in laparoscopic cholecystectomy (LC).

METHODSFrom 2003 to 2015, LC was performed on 21,497 patients, 7470 males and 14,027 females, age 50.3 years (14-84 years). The Calot's triangle was bluntly dissected and each duct in Calot's triangle was identified before transecting the cystic duct.

RESULTSTwo hundred and thirty-nine patients (1.1%) were converted to open procedures. The postoperative hospital stay was 2.1 (0-158) days, and cases (46%) had hospitalization days of 1 day or less, and 92.8% had hospitalization days of 3 days or less; BDI was occurred in 20 cases (0.09%) including 6 cases of common BDI, 2 cases of common hepatic duct injury, 1 case of right hepatic duct injury, 1 case of accessory right hepatic duct, 1 case of aberrant BDI 1 case of biliary stricture, 1 case of biliary duct perforation, 3 cases of hemobilia, and 4 cases of bile leakage.

CONCLUSIONExposing Calot's triangle by blunt dissection in laparoscopic cholecystectomy could prevent intraoperative BDI.

A 72-year-old man with jaundice by ampullary adenocarcinoma was treated at our hospital. For biliary decompression, a transpapillary, fully covered, self-expandable metal stent (FCSEMS) was deployed. Four days later, the patient developed acute cholangitis. Endoscopic carbon dioxide cholangiography revealed kinking of the common bile duct above the proximal end of the FCSEMS. A 7-F double-pigtail plastic stent was therefore placed through the FCSEMS to correct the kink, straightening the common bile duct (CBD) and improving cholangitis. This is the first report of a unique use of a double-pigtail plastic stent to correct CBD kinking. The placement of a double-pigtail plastic stent can correct CBD kinking, without requiring replacement or addition of a FCSEMS, and can lead to cost savings.

OBJECTIVETo investigate the value of Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (POSSUM) and a modification of the POSSUM system (P-P0SSUM) scoring system in predicting the surgical operative risk of pancreaticoduodenectomy for periampullary tumors.

METHODSPOSSUM and P-POSSUM scoring systems were used to retrospectively evaluate the clinical data of 432 patients with periampullar tumors who underwent pancreaticoduodenectomy in the Department of Abdominal Surgery, Cancer Hospital, Chinese Academy of Medical Sciences from January 1985 to December 2010. The predictive occurrence of postoperative complications and mortality rate were calculated according to the formula. ROC curve analysis and different group of risk factors were used to determine the discrimination ability of the two score systems, and to determine their predictive efficacy by comparing the actual and predictive complications and mortality rates, using Hosmer-Lemeshow test to determine the goodness of fit of the two scoring systems.

RESULTSThe average physiological score of the 432 patients was 16.1 ± 3.5, and the average surgical severity score was 19.6 ± 2.7. ROC curve analysis showed that the area under ROC curve for mortality predicted by POSSUM and P-POSSUM were 0.893 and 0.888, showing a non-significant difference (P > 0.05) between them. The area under ROC curve for operative complications predicted by POSSUM scoring system was 0.575. The POSSUM score system was most accurate for the prediction of complication rates of 20%-40%, showing the O/E value of 0.81. Compared with the POSSUM score system, P-POSSUM had better ability in the prediction of postoperative mortality, when the predicted value of mortality was greater than 15%, the predictive result was more accurate, and the O/E value was 1.00.

CONCLUSIONSPOSSUM and P-POSSUM scoring system have good value in predicting the mortality of patients with periampullary tumors undergoing pancreaticoduodenectomy, but a poorer value of POSSUM score system in prediction of complications. We can establish a more suitable scoring system for pancreaticoduodenectomy by modifying the score constant and weight, to better predict surgical risk and reduce the operative complications and mortality.
