Massive hemorrhagic abscess in the omental bursa caused by gallbladder perforation with bleeding： A case report

Subacute cholecystitis complicated by gallbladder perforation often manifests as inflammatory lesions around the gallbladder， and it is extremely rare for this condition to cause massive hemorrhage into the omental bursa with secondary infection and result in massive hemorrhagic abscess. This article reports a case of a female patient， aged 68 years， who experienced massive hemorrhagic abscess in the omental bursa due to localized perforation and bleeding caused by a stone impacted in the gallbladder neck. The patient had a history of gallstones for 30 years and was admitted to Tianjin Nankai Hospital， Tianjin Medical University， after tertiary referral due to aggravated abdominal pain， chills， and fever. After comprehensive assessment by a multidisciplinary team， the patient underwent emergency laparoscopic cholecystectomy and clearance of the hemorrhagic abscess in the omental bursa. The patient recovered well and was discharged on day 10 after surgery， with good conditions during follow-up.
