Abstract

Patients undergoing elective laparoscopic cholecystectomy from January 2010 to July 2016 were included in the study. Data collection was gathered from chart review and DVDs of all recorded laparoscopic cholecystectomy cases done in De La Salle University Medical Center. Subjects were classified as one of 2 groups, either with or without the presence of a Rouviere's fissure. Intraoperative events and complications were noted and compared among groups. A total of 494 patients were included in the study population. 319 patients were identified to have a Rouviere's fissure while the other 175 did not. Among those who presented with intraoperative complications/events, bleeding was shown to be the most frequent adverse event encountered in an elective laparoscopic cholecystectomy (184 events), followed by inadvertent gallbladder perforation and bile spillage (73 events). There is a relationship between the presence of Rouviere's fissure and the incidence of intraoperative events in patients who underwent elective laparoscopic cholecystectomy (x*=40.05, p-value < 0.0000001). A protective correlation was established with a Risk ratio 0.53; 95% confidence interval, 0.44 to 0.65.
