Objective To introduce the current status of clinical research on endoscopic cholecystolithotomy with reservation of gallbladder. Methods Literatures related to the basis, advantage, indication, contraindication, operative method and current controversy were reviewed and summarized. Results The objective evidences were afforded by postoperative complications of cholecystectomy for endoscopic cholecystolithotomy with reservation of gallbladder. The progress of endoscopic technique made it possible for reservation of gallbladder. The controversy in endoscopic cholecystolithotomy with reservation of gallbladder was focused on the choice of indications and operative procedure. Incorrect patient selection and undue pursuit of cholecystolithotomy with reservation of gallbladder would be completely opposite to the treatment of gallstone. Conclusion It is feasible for endoscopic cholecystolithotomy with reservation of gallbladder to remove completely stone and reserve gallbladder function, but further investigation and long-term follow up are required to delineate gallstone recurrence after operation.
ObjectiveTo evaluate the feasibility and surgical techniques of laparoscopic subtotal cholecystectomy （LSC) in treatment for patients with cholecystolithiasis combined with severe gallstone gallbladder inflammation, adhesion, or atrophy. MethodsThe clinical data of 83 patients with cholecystolithiasis combined with severe gallstone gallbladder inflammation, adhesion, or atrophy admitted to this hospital between January 2006 and April 2010 were analyzed retrospectively. ResultsEighty-one patients were performed LSC, 2 patients were converted to laparotomy. In which 39 patients with the part of wall residual of the fundus and (or) body of the gallbladder, 26 patients with residual of part of gallbladder neck, 18 patients with residual of part of gallbladder body and neck. Fifty-one cases were followed-up for 3 months to 4 years, there were 2 patients with the change like “mini gallbladder” by B ultrasound and no obviously clinical symptoms. There was no ostcholecystectomy syndrome in the patients with follow-up. ConclusionsLSC is a safe, effective, feasible procedure for severe gallstone gallbladder inflammation, adhesion, or atrophy, which can effectively prevent bile duct injury, bleeding, or other serious complications. While it can also reduce the rate of conversion to laparotomy.
ObjectiveTo investigate clinical efficacy and advantages and disadvantages of primary closure with two endoscopes (1aparoscope+choledochoscope) or three endoscopes (laparoscope+choledochoscope+duodenoscope) through the cystic duct for treatment of gallbladder stone with secondary common bile duct (CBD) stones.MethodsThe clinical data of 83 patients with gallbladder stones with secondary CBD stones treated by two or three endoscopes combined with CBD exploration and lithotomy and primary closure through cystic duct from January 2017 to December 2018 in the Chengdu Second People’s Hospital were collected retrospectively. Among them, 41 patients were treated by two endoscopes mode (two endoscopes group), 42 cases were treated by three endoscopes mode (three endoscopes group).ResultsThere were no significant differences in the general conditions such as the gender, age, preoperative diameter of CBD, chronic diseases, etc. between the two and three endoscopes group (P>0.05). All 83 cases underwent the operations successfully and recovered well. The success rate of operation, stone clearance rate, drainage volume of abdominal drainage tube on day 1 after the operation, time of abdominal drainage tube removal after the operation, and hospitalization time had no significant differences between these two groups (P>0.05). The time of operation, intraoperative bleeding volume, and the postoperative pancreatitis rate in the three endoscopes group were significantly more (or higher) than those in the two endoscopes group (P<0.05), but the condition of liver function recovered after the operation was better than that in the two endoscopes group (P<0.05).ConclusionsWith the strict control of the operation indications, it is safe and feasible to use two or three endoscopes through the cystic duct pathway and primary closure of CBD for treatment of gallbladder stone with secondary CBD stones. However, the choice of operative methods of two or three endoscopes should be based on the general situation of the patients before and during the operation.
ObjectiveTo summarize the research progress of long non-coding RNA (lncRNA) in the regulation of malignant biological behavior of gallbladder cancer so as to provide references for its related research.MethodThe relevant literatures about studies of lncRNA in gallbladder cancer in recent years were reviewed.ResultsThe recent studies had shown that 19 lncRNAs associated with gallbladder cancer had played the important roles in regulating tumor cell proliferation, migration, invasion, apoptosis, “sponge” miRNAs, chemoresistance, and tumor metastasis. Among them, most lncRNAs tended to have carcinogenic properties, only a few had anticarcinogenic effect. Although the research suggested the mechanism and role of lncRNA to promote or inhibit the occurrence and development of gallbladder cancer, the current research on its mechanism was still limited. In addition, some lncRNAs were found to be specifically expressed in the serum of patients with gallbladder cancer, so which were expected to become biomarkers for tumor diagnosis and prognosis.ConclusionslncRNAs associated with gallbladder cancer have carcinogenic or anticarcinogenic effect, or chemoresistance. They play potential roles in diagnosis, prognosis, and (or) treatment of tumors, but molecular mechanisms of their effects are still limited.
ObjectiveTo analyze risk and therapy strategy of tiny gallbladder stones during laparoscopic cholecystectomy (LC).MethodThe clinical data of 932 patients with tiny gallbladder stones performed LC from September 2013 to July 2014 were analyzed retrospectively.ResultsThe LC was successful in all the patients. The gallbladders were ruptured in 86 (9.23%) patients during operation. Following up 1-3 months, there were 26 patients with right upper abdominal pain and with residual small stones in the abdominal cavity, 57 patients without uncomfortable symptoms and without residual gallstone, 2 cases complicated with lesser abdominal abscess, 1 case complicated with incision infection. The incisional hernia and acute pancreatitis were not found.ConclusionsThe gallbladder with full of tiny stones performed LC easily leads to choledocholithiasis or acute pancreatitis. If intraoperative gallbladder rupture, the tiny stones might be residual in the peritoneal cavity and lead to abdominal infection or abscess, and incision infection or trocar site hernia. Specific operation could effectively avoid adverse complications.
ObjectiveTo investigate the long-term efficacy of laparoscopic cholecystectomy (LC) for gallbladder cancer.MethodThe clinical data of 52 patients with gallbladder cancer only underwent LC from January 1998 to December 2018 in the Peking Union Medical College Hospital were analyzed retrospectively.ResultsFifty-two patients met the inclusion criteria were included, including 23 males and 29 females. The age was (67±12) years. Fifty-two patients were treated with LC because of gallbladder occupying or gallstone. Twenty-three patients were diagnosed as incidental gallbladder cancer after the surgery, while 29 patients were diagnosed as the gallbladder cancer before or during the operation. Eleven patients with T1a lesions received the close follow-up, the other 41 patients refused the radical operation due to the advanced age, severe underlying diseases or their own preferences. Five cases of postoperative complications were observed. All patients were followed-up for (40.2±33.8) months, 21 patients survived and 31 died. The dead patients had an older age, longer hospital stays, and later T stage (P<0.050) as compared with the living patients. The patients with T1a lesions had significantly longer survival time than those with T1b and above (113.5 months versus 39.6 months, P<0.001).ConclusionsLC is a radical operation in T1a lesions. At the same time, it can meet the requirements of postoperative life quality for some special patients due to its safety and low postoperative complication rate.
ObjectiveTo study the relationship among cholecystectomy/gallbladder disease and bile reflux gastritis.MethodsA retrospective collection of 123 patients with bile reflux gastritis who were diagnosed as outpatients and hospitalized from January 2014 to February 2019 in Shengjing Hospital Affiliated to China Medical University, and 221 patients with non-biliary reflux gastritis at the same period were collected. According to the gallbladder status, the patients were divided into three groups: gallbladder disease, cholecystectomy, and gallbladder disease-free group. The relationship between gallbladder status and bile reflux gastritis was analyzed.ResultsAmong 123 patients with bile reflux gastritis, there were 22 cases (17.89%) with cholecystectomy and 26 cases (21.14%) with gallbladder disease; 221 cases of non-biliary reflux gastritis with cholecystectomy in 7 cases (3.17%) and gallbladder disease in 30 cases (13.57%). Univariate analysis showed that the gallbladder status was different between the bile reflux gastritis group and the non-biliary reflux gastritis group (χ2=21.089, P<0.001). The study showed that the gallbladder status was related to the occurrence of bile reflux gastritis. In contrast, patients with cholecystectomy and gallbladder disease had a higher risk of occurrence than those with no gallbladder disease (OR>1, P<0.012 5). Independent risk factors were considered by logistic multivariate regression analysis, including cholecystectomy, gallbladder disease, and age (P<0.05).ConclusionsThere is a correlation between cholecystectomy/gallbladder disease and bile reflux gastritis. Cholecystectomy and gallbladder disease may be the independent risk factors for bile reflux gastritis.
The “Expert consensus on radical laparoscopic cholecystectomy (2023)” (following abbreviations as “this consensus”) was formulated by the Biliary Surgery Group of the Chinese Medical Association Surgery Branch and the Biliary Surgery Expert Working Group of the Surgeons Branch of the Chinese Medical Doctor Association, and was first published in the Chinese Journal of Surgery in April 2024. In this consensus, relevant experts discussed and formulated relevant recommendations on the operation process of laparoscopicradical resection of gallbladder cancer (LRRGC), and elaborated on many issues. We interpreted and discussed the safety and efficacy evaluation of LRRGC, the standardized operating procedures and technical key points in this procedure, as well as the surgical principles for reoperation of delayed diagnosed gallbladder cancer in this consensus so as to enhance readers’ understanding of this consensus. We also hoped that medical centers will make more attempts and research on LRRGC in order to standardize and promote the application of LRRGC.
Objective To observe the expression of Ezrin protein in primary carcinoma of gallbladder tissue and the levels of CEA and CA19-9 in serum of patients with primary carcinoma of gallbladder, and to explore the relationship between the expressions of these measurements and clinicopathologic characteristics. Methods Immunohistochemistry was applied to analyze the expression of Ezrin protein in primary carcinoma of gallbladder and chronic cholecystitis tissue. The levels of CEA and CA19-9 in serum and clinicopathologic characteristics of all including patients were detected with clinical measurement. All data were analyzed statistically. Results ①The positive rates of Ezrin protein in primary carcinoma of gallbladder and chronic cholecystitis tissue were 66.7% （40/60） and 30.8%（4/13）, respectively (χ2=5.57, Plt;0.05). ②There was no difference between the expression of Ezrin protein in primary carcinoma of gallbladder tissue and age or gender (Pgt;0.05). However, difference was significant between the Ezrin expression and degree of difference, pNevin stages, pTNM stages, lymph node metastasis or distant metastasis (Plt;0.05). ③There were no differences between the positive rates of CEA and CA19-9 in primary carcinoma of gallbladder and age or gender (Pgt;0.05). However, differences were significant between the positive rates of CEA and CA19-9 and pNevin stages, pTNM stages, degree of difference, lymph node metastasis or distant metastasis (Plt;0.05). ④There was some relationship between the expression of Ezrin protein and the positive rate of CEA (rs=0.213, Plt;0.05), but not with the positive rate of CA19-9 (rs=0.081, Pgt;0.05). Conclusions The high expression of Ezrin protein may promote the invasion and metastasis in primary carcinoma of gallbladder. It could be possible to decide the outcome of primary carcinoma of gallbladder through the combined analysis on the expression of Ezrin protein and the serum levels of CEA and CA19-9.
