Dropped gallstone-related perihepatic abscess 20 years after open cholecystectomy

INTRODUCTION: Gallstone spillage during cholecystectomy is a recognized complication that can lead to various postoperative complications. CASE PRESENTATION: We present a rare case of a gallstone abscess that developed 20 years after an open cholecystectomy. An 80-year-old woman with a history of high blood pressure and previous gallbladder removal presented with severe abdominal pain. Imaging revealed a large abscess with a suspicious calcification, indicating a lost gallstone. Surgical intervention was performed, resulting in the removal of multiple gallstone fragments from the abscess cavity. CLINICAL DISCUSSION: Gallbladder perforations and the spillage of gallstones are common complications during cholecystectomies, with laparoscopic procedures being more prone to stone spillage. Studies show a significant difference between open and laparoscopic cholecystectomies, with laparoscopy having a higher risk of spilled stones. Complications from spilled gallstones are rare but can vary in presentation and location. They may lead to long-term issues such as abscesses and even erosion into other organs. These complications can manifest years after surgery. Treatment involves evacuating the abscess and addressing the gallstone. Surgical intervention, like laparotomy or laparoscopy, is required for retrieval. Ensuring proper traction during surgery is crucial to prevent gallbladder perforation and stone spillage. Consideration of alternative, gentler instruments for traction may be beneficial. CONCLUSION: Surgeons should be vigilant, proactive, and employ prophylactic measures to minimize complications related to gallstone spillage, ensuring the best possible patient outcomes.
