Gastrointestinal subepithelial tumors (GSTs), incidentally detected during upper gastrointestinal (GI) endoscopy, may be lesions derived from the GI wall or may be caused by compression from external organs. In general, traumatic neuroma is a benign nerve tumor that results from postoperative nerve injury, occurring in the bile duct as one of the complications after cholecystectomy. This is the first case report demonstrating that neuroma of the cystic duct can be incorrectly perceived as a duodenal subepithelial tumor by compressing the duodenal wall.
We report the case of a 72-year-old man with traumatic neuroma of the cystic duct after cholecystectomy. This tumor was mistaken for a duodenal subepithelial tumor on preoperative upper GI endoscopy and endoscopic ultrasonography due to external compression of the GI wall. The patient had no symptoms, and his laboratory test results were normal. However, in a series of follow-up endoscopies, the tumor was found to have grown in size, so it was surgically resected. The lesion was completely removed by laparoscopic endoscopic cooperative surgery. The patient was discharged on postoperative day 7 without complications.
Traumatic neuroma of the cystic duct can be mistaken for GSTs in GI endoscopy.
Core tip: Traumatic neuroma of the cystic duct is rare. In these cases; we have shown that this tumor can be mistaken for gastrointestinal subepithelial tumors (GSTs) by compression of the gastrointestinal wall. Abdominal computed tomography reports and patients’ medical history need to be considered before choosing surgical ablation of GSTs. In addition, it is recommended to consider laparoscopy and endoscopy cooperative surgery when surgically resecting a gastroduodenal subepithelial tumor.
