Background:
Amputation neuromas (ANs) are reactive hyperplasia of nerve tissues that occur after a trauma or surgery involving the peripheral nerves. Only two previous reports of ANs occurring around the stomach and post gastrectomy have been reported. We report the case of a patient with AN near the remnant stomach who underwent distal gastrectom...

... con- trast-enhanced computed tomography (CT) failed to de- tect the primary lesion; however, a slightly enhanced 13 × 10-mm nodule was observed near the lesser curvature of the remnant stomach (Fig. 1a). An endoscopic ultrasonog- raphy (EUS) revealed a hypoechoic lesion without vascular flow, and the margin of the lesion was slightly indistinct (Fig. 2). An endoscopic ultrasonography-guided fine nee- dle aspiration (EUS-FNA) of the nodule showed no cancer cells. Following a clinical diagnosis of early gastric cancer confined to the mucosa (T1a) without lymph node metas- tasis, endoscopic submucosal dissection (ESD) was per- formed. The histopathological examination revealed Type ...

... Given that many nerves normally surround the extrahepatic bile duct, the number of symptomatic patients was lower than that expected. Some patients are asymptomatic, and lesions can be detected accidentally on radiological examinations [7,51]. ...
Traumatic neuroma (TN) is a disorganized proliferation of injured nerves arising from the axons and Schwann cells. Although TN rarely occurs in the abdominal cavity, the incidence of TN may be underestimated because of the large number of asymptomatic patients. TN can cause persistent pain, which seriously affects quality of life. TN of the biliary system can cause bile duct obstruction, leading to acute cholangitis. It is difficult to differentiate TN from malignancies or recurrence of malignancy, which results in a number of patients receiving aggressive treatment. We collected cases reports of intra-abdominal TN over the past 30 years form PubMed and cases diagnosed in our medical center over the past 20 years, which is the largest case series of intra-abdominal TN to the best of our knowledge. In this review, we discuss the epidemiology, pathophysiology, risk factors, classification, diagnosis, and management of intra-abdominal TN.
