Gallbladder perforation into the greater omentum following sleeve gastrectomy: A case report study

INTRODUCTION: Obesity is considered a major risk factor for gallstone formation and is important due to its increasing prevalence worldwide. Many studies have reported an increased incidence of gallstone formation following bariatric surgery. This report documents a rare case of a complicated cholecystitis following sleeve gastrectomy and describes our management of the case and the management options for gallbladder disease in bariatric patients. PRESENTATION OF CASE: A 60-year-old male was diagnosed with asymptomatic cholelithiasis at the time of sleeve gastrectomy for obesity treatment. Two months after the procedure, he presented to the emergency department with symptoms of acute cholecystitis, which were initially managed conservatively. Six weeks later, he underwent a laparoscopic cholecystectomy. Intra-operative findings revealed a rare case of a complicated cholecystitis where the gallstone was half-eroded into the greater omentum. DISCUSSION: A notable proportion of bariatric patients develop symptomatic complicated cholecystitis following laparoscopic sleeve gastrectomy, compared to the normal population. Furthermore, complications develop quickly and technical difficulties are associated with subsequent surgeries. Thus, early cholecystectomy is justified. CONCLUSION: Patients with asymptomatic cholelithiasis, undergoing sleeve gastrectomy, may benefit from concomitant cholecystectomy. The question is yet controversial. This highlights the need for more clinical research in the field.
