Remnant Cholecystitis After Subtotal Cholecystectomy: A Case Report

Remnant cholecystitis is a rare complication following subtotal cholecystectomy (STC), particularly when the reconstituting technique is used, which leaves a portion of the gallbladder behind. This remnant can become inflamed due to recurrent or retained gallstones. We present the case of a 39-year-old female who required a completion cholecystectomy 11 years after her initial STC due to severe recurrent right upper quadrant (RUQ) pain, nausea, and vomiting with an ultrasound that revealed cholelithiasis. This case highlights the need for increased awareness of remnant cholecystitis, better diagnostic approaches, and standardized management guidelines to prevent long-term complications. Further research is necessary to improve the treatment of this rare condition and optimize patient outcomes.
