We reviewed the clinical studies on drug therapy for gallbladder cancer and expounded on the current situation of conversion therapy for gallbladder cancer. Gallbladder cancer was usually diagnosed late, with high malignancy, low surgical resection rate, and poor prognosis. With the development of conversion therapy, systemic therapy combined with radical resection had effectively improved the surgical resection rate and prognosis of gallbladder cancer patients. At present, most of the published conversion therapies for gallbladder cancer were mainly retrospective researches, lacking large multicenter prospective research, and the treatment plan was still based on chemotherapy, lacking the research of targeted therapy in combination with immunotherapy. It is expected that more high-quality clinical trials can be made first-line recommendations for the conversion therapy of gallbladder cancer.
Objective To investigate the role of KiSS-1 gene in the metastatic process of carcinoma of gallbladder and the clinicopathologic significance of KiSS-1 gene expression in carcinoma of gallbladder. Methods Pathological specimens from 59 gallbladder carcinoma tissues (13 hepatic invasion and 13 lymphatic invasion tissues were included), matched with 7 para-tumor and 6 normal gallbladder tissues, were examined for the expression of KiSS-1 gene by tissue microarray technique and immunohistochemistry (EnVision). Results The positive rate of KiSS-1 expression was down-regulated (P＜0.05) in tumor tissues, as compared with normal and para-tumor tissues. In carcinoma of gallbladder, the expression of KiSS-1 had no relationship with the gender, age, tumor size, histological grade or differentiation, and metastasis of lymph node, while was associated with the depth of infiltration, invasion of liver and the clinical stages (Nevin). In Ⅰ+Ⅱ, Ⅲ+Ⅳ and Ⅴ stage, the positive rates of KiSS-1 were 92.3%, 57.1% and 27.8% respectively, with an undeniably clear lowering tendency (P=0.002). Conclusion Down-regulating expression of KiSS-1 is closely associated with the processes of genesis, invasion and metastasis in carcinoma of gallbladder, and may participate in regulating these processes.
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.
Objective To study the association and the effect of the expression of p16 and p53 protein on the occurence and development of gallbladder carcinoma. Methods The expression of p16 and p53 protein were detected in 40 cases of gallbladder carcinoma with immunohistochemical method. Results The expressions of p16 and p53 protein were closely correlated to the tumor pathological grade, lymph mode metastasis and prognosis. p16 protein was correlated to the Nevin classifications. Conclusion The results indicate that the low expression rate of p16 protein occurred in the advanced stage of gallbladder carcinoma. The expression of p16 and p53 protein are helpful in judging the malignant degree and prognosis of primary gallbladder cancer.
【Abstract】ObjectiveTo study the spiral CT features of gastrointestinal invasion by carcinoma of gallbladder. MethodsEight patients with surgical-pathologically documented gastrointestinal invasion by carcinoma of gallbladder were analyzed retrospectively. All patients underwent plain and contrast-enhanced dual-phase scanning of the abdomen. Oral contrast medium (1.2% Angiografin) was used to fill the gastrointestinal tract before CT scanning. ResultsThere were 2 cases of gastric antrum invasion, 6 duodenal invasion and 3 colonic invasion according to the surgical and pathological findings. Spiral CT correctly diagnosed 2 gastric invasion and 4 duodenal invasion based on several imaging features, like blurring of fat plane, focal wall thickening and luminal narrowing of involved gastrointestinal segments, and mass formation. However CT was unable to diagnose the 3 cases of hepatic flexure of colon invasion. ConclusionCT is valuable for diagnosing upper gastrointestinal tract invasion by carcinoma of gallbladder, yet the diagnosis of hepatic flexure of colon invasion is still difficult.
Objective To explore the feasibility， operation method， and clinical application value of transumbilical single-port laparoscopic cholecystectomy （TUSP-LC） in treatment for children patients with benign gallbladder diseases. Methods The clinical data of 64 patients with benign gallbladder diseases from June 2009 to June 2011 were analyzed retrospectively. The patients were divided into TUSP-LC group （n=41） and convention three-port LC （CTP-LC group， n=23）. The operative time， intraoperative blood loss， conversion to CTP-LC or laparotomy， operative complications， and hospital stay were recorded. The pains were registered at 3，6，12，24，48， and 72h postoperatively using visual analog scale （VAS）. The patients were given satisfaction questionnaires with surgery at 6 time points （1 week， 2 weeks， 1 month， 3 months， 6 months， 12 months） during a 12 months follow-up. Results A total of 64 pediatric LCs were performed successfully， no patients were converted to laparotomy. Except for one case of incision infection in the CTP-LC group 〔4.35%（1/23）〕 and one case of incision infection and one case of ecchymoma in the TUSP-LC group 〔4.88% （2/41）〕， no other complications such as bile duct injury， bile leakage， and incision hernia happened， the total complication rate was not significant difference in two groups （P＞0.05）. The operative time 〔（47.54±18.71） min versus（45.33±10.58） min〕， intraoperative blood loss 〔（18.56±13.34） ml versus （17.28±12.53） ml〕， and hospital stay 〔（1.67±0.36） d versus （1.81±0.38） d〕were not significant differences in two groups （P＞0.05）. The VAS score was not statisticly significant within 24h in two groups （P＞0.05）， but which in the TUSP-LC group was significantly lower than that in the CTP-LC group after 24h postoperatively （P＜0.05）. During a 12 months follow-up， the score of satisfaction in the TUSP-LC group was significantly higher than that in the CTP-LC group （P＜0.05）. Conclusions TUSP-LC is a safe and feasible method in the children patients with benign gallbladder diseases. It can be performed with the same technical exposure and outcomes as multi-port laparoscopy， with the added benefit of relieving postoperative pain and little no scarring.
ObjectiveTo investigate the value of single incision laparoscopic cholecystectomy in the operation of benign diseases of the gallbladder in day surgery.MethodThe clinical data of 105 patients underwent the single incision laparoscopic cholecystectomy in the Day Operation Center of Zhengzhou Central Hospital of Zhengzhou University from March 2017 to December 2018 were retrospectively analyzed.ResultsThe single incision laparoscopic cholecystectomies were successfully performed in 105 patients with benign gallbladder diseases, including 65 cases of gallbladder stones, 26 cases of gallbladder polyps, 14 cases of gallbladder adenomyosis; 45 cases of men and 60 cases of women. In all cases, no incision was increased or no case was converted to laparotomy. No bile duct injury and intra-abdominal bleeding happened during the operation. All patients were discharged overnight (no more than 24 h) after the surgery and without delayed discharge and re-admission. The intraoperative blood loss was (10.3±3.5) mL, and the operation time was (55.0±25.5) min (from laparoscopy to gallbladder removal). The postoperative pain score was 1–2 and 0–1 on day 1 and on day 3 after the surgery, respectively. The postoperative incision cosmetic satisfaction score on month 6 after the operation was 4.5±0.5.ConclusionSingle incision laparoscopic cholecystectomy is safe and feasible for benign gallbladder disease during day surgery.
ObjectiveTo explore the suitable method for isolation and maintenance of primary cultures of human gallbladder epithelial cells (GECs) for establishing the basis of research works in physiological function of gallbladder and its related diseases.MethodsGECs were isolated with collagenase type Ⅳ and blunt separation.The dishes were coated with fibronectin, laminin and polyDlysine respectively.Additional 10 ng/ml epidermal growth factor was added to DMEM medium containing 20% fetal calf serum.The cells were studied under light and electron microscope to determine their shape and distribution.ResultsEach gallbladder yielded approximately (1-5)×107columnar epithelial cells,greater than 95% of which were viable by trypan blue exclusion.The cells grew vigorously within one week which was flat and multangular in shape. CK19 expressed positive.Electron microscope showed typical gallbladder epithelia with microvilli,tight junctions and mucus droplets.ConclusionCombination of collagenase type Ⅳ，mechanical blunt separation and twostep attachment is of great benefit for separating and harvesting GEC.Fibronectin coated culture dish and DMEM medium containing 20% calf serum and 10 ng/ml hEGF is of great benefit for culturing gallbladder epithelial cells.
ObjectiveTo discuss the reason and treatment strategy of gallbladder muddy stones after cholecysto-lithotomy. MethodsThe clinical data of 62 patients with gallbladder muddy stones after cholecystolithotomy who were treated in our hospital from December 2008 to December 2014 was analyzed retrospectively. ResultsThere were 43 patients without any symptom and 19 patients with acute cholecystitis in 62 patients. Four patients were diagnosed with septation gallbladder, 6 patients with long and tortuous cystic duct, 3 patients with calculus of cystic duct, 4 patients with common bile duct stones, 39 patients with periampullary diverticula, 18 patients with pancreaticobiliary maljunction, 6 patients with duodenal papilla stenosis, 29 patients with duodenal papillitis, and 3 patients with duodenal papilla adenocarcinoma. Two patients were treated with laparoscopic cholecystectomy (LC), 1 patient with endoscopic sphincterotomy (EST) /endoscopic balloon dilation (EPBD) and LC, 1 patient with percutaneous transhepafic gallbladder drainage (PTGD) and open cholec-ystectomy, 14 patients with PTGD and EST/EPBD, 1 patient with PTGD and hepatocholangioplasty with the use of gallbladder (HG), 34 patients with EST/EPBD, 3 patients with EST/EPBD and endoscopic biliay metal stent drainage (EBMSD), 5 patients with HG, and 1 patient with EST/EPBD and HG. The gallbladder muddy stones disappeared after operations in 55 patients with gallbladder reserved, and gallbladder ejection fraction increased from (42±12) % to (59±16) %. Of the 62 patients, 53 patients were followed up for 6 months to 6 years (the median time was 3.6-year). During the follow-up period, 3 patients were diagnosed with gallbladder stones, 2 patients with common bile duct stones, and 2 patients with intrahepatic and extrahepatic bile duct stones. ConclusionBile efferent tract obstruction is the important reason for the formation of gallbladder stones. HG, EST, and balloon expansion are the efficient methods to resolve the bile efferent tract obstruction.
