ABSTRACT
Based on current diagnosis and treatment of gallbladder disease, the occur-rence of incidental gallbladder cancer is partly caused by the irregular clinical diagnosis and treatment process of gallbladder disease, which leads to the failure to make the diagnosis of gallbladder cancer in time, carry out the correct preoperative and intraoperative staging, and cause R 1 or R 2 resection. The authors summarize standardized diagnosis and treatment process of gallbladder disease and technical details. In clinical practice, the concept of incidental gallbladder cancer should be discarded, and various gallbladder diseases should be taken as a whole. A more standardized diagnosis and treatment process should be established to improve the diagnostic accuracy of gallbladder cancer and achieve radical resection, which eventually improve survival of patients.
ABSTRACT
Gallbladder cancer is a high malignancy which is predisposed to invade adjacent organs and have lymph node metastasis. Gallbladder cancer is not sensitive to radiotherapy or chemotherapy with the worst prognosis among biliary tract cancers. At present, radical resection is the only possible method to cure gallbladder cancer. However, there are still many controversies about the surgical strategies, the extent of liver resection and lymph node dissection, and the treatment of incidental gallbladder cancer. In addition, under the background of the great success of immunotherapy and targeted therapy in a variety of solid tumors, it is also a question worthy of further considerations that whether the status of surgery in the treatment of advanced gallbladder cancer will be changed in the near future.
ABSTRACT
Objective To compare the tumor characteristics and survival between postoperative incidentally discovered gallbladder cancer (ID-GBC) and preoperatively suspected gallbladder cancer (PS-GBC).Methods The data of 276 GBC patients who underwent surgical resection with curative intent between January 2004 and December 2014 at the Eastern Hepatobiliary Surgery Hospital were retrospectively analyzed.Results The 1-,3-,and 5-year cumulative survival rates of the ID-GBC group (88.8％,52.2％,and 33.0％,respectively) were significantly better than those in the PS-GBC group (57.5％,25.7％,and 16.6％,P ＜ 0.05).In the ID-GBC group,multivariate analysis revealed that T staging,hepatic invasion and time interval from cholecystectomy to re-operation were independent prognostic factors.The overall survival (OS) in the group with the time interval within 2 weeks was significantly better than those in the other two groups (both P ＜ 0.05).However,there were no significant differences in OS between the groups with the time interval of 2 weeks to 1 month and more than 1 month (P ＞ 0.05).Conclusions Postoperative ID-GBC had significantly better survival outcomes than PS-GBC.Reoperation within two weeks in patients with ID-GBC is a good strategy.
ABSTRACT
Objective To investigate the treatment strategy for the re-operation patients with gallbladder cancer revealed by pathological results after laparoscopic cholecystectomy .Methods The clinical data in 15 cases of gallbladder cancer found by pa-thology after laparoscopic cholecystectomy in the general surgery department of this hospital during 2009-2013 were retrospective-ly analyzed .Results The pathological results on 3-5 d after laparoscopic cholecystectomy in 15 cases showed gallbladder cancer , tumor located at the gallbladder fundus in 2 cases ,the gallbladder body in 2 cases and gallbladder neck in 9 cases;there were 1 case of severe atypical hyperplasia ,2 cases of high differentiation adenocarcinoma ,9 cases of middle differentiation adenocarcinoma and 3 cases of low differentiation adenocarcinoma ;there were 1 case of Tis ,8 cases of pT Ⅰa ,6 cases of pTⅠb ,and 15 cases of bile tube incisal edge were negative .All 15 cases received re-laparotomy and hepatic duodenal ligament lymph nodes resection on 6-11 d af-ter cholecystectomy ,There were 1 case in the stage 0 ,8 cases in the stage Ⅰa ,5 cases in the stage Ⅰb ,1 case in the stage Ⅲb by TNM classification .The postoperative follow up lasted for 28 -79 months ,the accumulative survival rate was 100% in 1 year , 100% in 2 year ,93% in 3 year ,93% in 5 year .One case of stage Ⅲb was found repeated metastasis obstructive jaundice ,received transcutaneous puncture bile tract drainage and died after 3 months;no postoperative incision implantation metastasis was found . Conclusion Gallbladder cancer found by pathological examination after laparoscopic cholecystectomy is generally in early stage . Therefore ,early conducting the additional hepatic duodenal ligament lymphadenectomy has relatively good prognosis .
ABSTRACT
BACKGROUND: Because there may be interdepartmental differences in macroscopic sampling of cholecystectomy specimens, we aimed to investigate differences between the longitudinal sampling technique and our classical sampling technique in cholecystectomy specimens in which there was no obvious malignancy. METHODS: Six hundred eight cholecystectomy specimens that were collected between 2011 and 2012 were included in this study. The first group included 273 specimens for which one sample was taken from each of the fundus, body, and neck regions (our classical technique). The second group included 335 specimens for which samples taken from the neck region and lengthwise from the fundus toward the neck were placed together in one cassette (longitudinal sampling). The Pearson chi-square, Fisher exact, and ANOVA tests were used and differences were considered significant at p<.05. RESULTS: In the statistical analysis, although gallbladders in the first group were bigger, the average length of the samples taken in the second group was greater. Inflammatory cells, pyloric metaplasia, intestinal metaplasia, low grade dysplasia, and invasive carcinoma were seen more often in the second group. CONCLUSIONS: In our study, the use of a longitudinal sampling technique enabled us to examine a longer mucosa and to detect more mucosal lesions than did our classical technique. Thus, longitudinal sampling can be an effective technique in detecting preinvasive lesions.

Background Incidental gallbladder cancer is found in upto 1% of cholecystectomy specimens for gallstone disease. Currently, in our institution, all gallbladder specimens are sent for routine histopathology, to rule out incidental gallbladder carcinoma. This study was aimed at assessing the need for routine histopathology of gallbladder specimens after cholecystectomy for gallstone disease. Methods Hospital records of all patients undergoing cholecystectomy for gallstone disease over a ten-year period, between 1998 and 2007, in a single surgical unit were reviewed. Results A total of 1312 patients underwent cholecystectomy for gallstone disease. Gallbladder carcinoma was detected in 13 patients. Macroscopic abnormalities of the gallbladder were found in all the 13 patients. In patients with a macroscopically normal gallbladder, there were no cases of gallbladder carcinoma. Conclusion Gallbladder carcinoma is associated with macroscopic abnormalities in all cases. Therefore histopathology should be restricted to only those specimens which reveal a macroscopic abnormality. This would identify all cases of incidental gallbladder carcinoma, at the same time decreasing cost and pathological work load.
