Traumatic Neuroma Arising from Surgical Trauma during Conversion from Laparoscopic to Open Cholecystectomy.

Traumatic neuroma is an abnormal proliferation of injured nerves resulting from trauma or surgery. We present a case of traumatic neuroma arising in the cystic duct after cholecystectomy. A 66-year-old man was referred to our department due to a biliary tumor.

Two Cases of Pylorus-Preserving Pancreatoduodenectomy with Remnant Stomach Preservation in Patients Who Have Undergone Proximal Gastrectomy.

Introduction: Pancreaticoduodenectomy after proximal gastrectomy (PG) presents technical challenges owing to the need to preserve blood flow in the remnant stomach. Considering the oncological factors and preservation of the remnant stomach blood supply, it is crucial to preserve or reconstruct the right gastric artery (RGA) and/or right gastroepiploic artery (RGEA). In cases where the RGEA is preserved, technical considerations for reconstruction arise owing to the poor motility of the remnant stomach.

Importance of Lymph Node Metastasis to the Pancreatic Head Region in Patients with Ampulla of Vater Carcinoma.

Introduction: Owing to their rarity, clinicopathologic variables and postoperative outcomes in patients with ampulla of Vater carcinoma (AVC) have not been fully elucidated.

Materials And Methods: A retrospective review of the clinical records of patients who underwent surgical exploration for AVC was performed using univariate and multivariate analyses.

Results: One-, three-, and five-year overall survival rates after surgery were 97.

Hepatic methotrexate-associated lymphoproliferative disease: a case report and literature review.

Background: Methotrexate-associated lymphoproliferative disease (MTX-LPD) is a rare and life-threatening complication of MTX administration. MTX-LPD features more extranodal lesions than malignant lymphoma; however, the liver is an extremely rare organ that develops LPD. Herein, we present a case of hepatic MTX-LPD treated with surgical resection.

Occult Nesidioblastosis Detected by 111In-Pentetreotide Single-Photon Emission Computed Tomography.

Nesidioblastosis, also known as persistent hyperinsulinemic hypoglycemia, is usually observed in children and infants, although more recently adult-onset nesidioblastosis has also been described. We present a case of nesidioblastosis in a 78-year-old man that was detected by 111In-pentetreotide single photon emission computed tomography (SPECT/CT). The patient was transferred to our hospital's emergency department in a hypoglycemic coma.
