Minimally invasive approach in a rare emergency surgery, gallbladder perforation

Background Gallbladder perforations are challenging to manage for surgeons due to their high morbidity and mortality, rarity, and surgical approach. Laparoscopic cholecystectomy (LC) is now included with open cholecystectomy in surgical managing gallbladder perforations. This study aimed to evaluate the factors affecting conversion from laparoscopic to open cholecystectomy in cases of type I gallbladder perforation according to the Modified Niemeier classification. Methods Patients who met the inclusion criteria were divided into two groups: LC and conversion to open cholecystectomy (COC). Demographic, clinical, radiologic, intraoperative, and postoperative factors were compared between groups. Results This study included 42 patients who met the inclusion criteria, of which 28 were in the LC group and 14 were in the COC group. Their median age was 68 (55-85) years. Age did not differ significantly between groups (p = 0.218). However, the sex distribution did differ significantly between groups (p = 0.025). The location of the perforation differed significantly between groups (p < 0.001). In the LC group, 22 patients were perforated from the fundus, four from the trunk, and two from the neck. In the COC group, two patients were perforated from the fundus, four from the trunk, and eight from the neck. Surgical procedure times differed significantly between the LC (105.0 min [60-225]) and COC (125.0 min [110-180]) groups (p = 0.035). The age of the primary surgeons also differed significantly between the LC (42 years [34-63]) and COC (55 years [36-59]) groups (p = 0.001). Conclusions LC can be safely performed for modified Niemeier type I gallbladder perforations. The proximity of the perforation site to Calot's triangle, Charlson comorbidity index (CCI), and Tokyo classification are factors affecting conversion from laparoscopic to open surgery of gallbladder perforations.
