Introduction: Subtotal cholecystectomy is a procedure reserved for severe cholecystitis where the patient conditions are unstable and it is not possible to identify the structures of the Calot triangle. It is considered a safe procedure, however occasional reoperation may be necessary. Objective: The goal of the study is report two cases of reoperation for reformed gallbladder after subtotal cholecystectomy in a single center and to conduct a literature review on reformed gallbladders after incomplete gallbladder removal. Method: A literature search of PubMed and EMBASE (1985 – February 2015) was conducted. Search criteria included “reformed gallbladder” “subtotal cholecystectomy” “partial cholecystectomy” “reoperation” “remnant gallbladder” “retained gallbladder” using the Boolean operators “AND” “OR”, limited to title or abstract with publication in the English. The bibliographies of the recovered articles were examined to find supplementary references of data. Results: Literature review included twenty-one publications, excluding five articles that did not mention reoperation for remnant gallbladder. Repeated articles describing the same case were excluded, the one containing the most complete information was analysed. We found 38 cases of “recholecystectomy” in the literature. Most of them (30 cases) were reoperated laparoscopically. The interval between first and second surgery ranged from 2 weeks to 32 years. Indications for reoperation were more frequently right upper quadrant pain. Conclusion: Literature with reference to subtotal cholecystectomy and reformed gallbladder is scarce. This surgery became an important technique used mainly for cases of severe cholecystitis. Caution is necessary since diagnosis for reformed gallbladder is unusual and the reoperation increases morbidity rates.
