A Rare Case of Poorly Differentiated Lower Esophageal Cancer with Neuroendocrine Differentiation and α-Fetoprotein Production

Mamiko Takii, et al.

INTRODUCTION: Neuroendocrine differentiation and α-fetoprotein production (AFP) are 2 rarely reported features in poorly differentiated gastric carcinomas. We report an extremely rare case of esophageal carcinoma (EC) featuring both histologic types.

Fiber-Guided Red Light-Emitting Diode Localization of an Esophageal Blind End in Long-Gap Esophageal Atresia Surgery: A Case Report

Hiroki Kanamori, et al.

INTRODUCTION: Esophageal atresia (EA) Gross type A is a congenital malformation in which both the upper and lower esophagus have blind ends without a tracheoesophageal fistula. The gap between the segments is often long (long-gap EA), making intraoperative localization challenging. We report a case in which the lower esophageal blind end was readily localized using Tumguide (Otsuka Pharmaceutical Factory, Tokushima, Japan), a device that transmits biologically transparent red light from a light-emitting diode (LED) through an optical fiber.

Laparoscopic Repair of a Sciatic Hernia Using a Self-Fixating Mesh: A Case Report

Kimihiro Hattori, et al.

INTRODUCTION: A hernia that protrudes through the sciatic foramen is called a sciatic hernia and is classified as a pelvic hernia, although it is the rarest type. We aimed to report a case of elective laparoscopic repair of a sciatic hernia using a self-fixating mesh.

The Realization of a Remote Robotic Breast Surgery

Fujun Shi, et al.

INTRODUCTION: While remote telesurgery has advanced fields like urology and general surgery, its application in breast oncology remains unreported. We present a successful case of remote robotic nipple-sparing mastectomy (rNSM), which preliminarily confirms its technical feasibility and perioperative safety.

Solitary Hepatic Metastasis of Thymoma: A Case Report

Hiroshi Sakai, et al.

INTRODUCTION: Hepatic recurrence of thymomas is uncommon and its surgical treatment has rarely been reported. We report the case of a patient who underwent surgical resection for a solitary liver metastasis of a thymoma.

A Successfully Treated Case of Pediatric Traumatic Gastric Rupture Caused by Seat Belt Injury

Yumiko Tabata, et al.

INTRODUCTION: Gastrointestinal tract injury is estimated to occur in 0.9%–1% of blunt trauma cases, with gastric rupture occurring in approximately 3% of these cases. Blunt trauma injuries of the stomach are rare. In comparison to solid organ injuries, gastrointestinal tract injuries are less likely to be accompanied by hemorrhaging that can cause hemorrhagic shock, and the process is considered to be relatively slow.

Rupture of a Hepatic Hemangioma in the Remnant Liver Following Hybrid Extended Left Hemihepatectomy in a Living Liver Donor: A Case Report

Rei Tsunoda, et al.

INTRODUCTION: Hepatic hemangiomas have occasionally been identified in donor liver grafts. However, rupture of a hemangioma in the remnant liver following liver graft harvest in a living donor has not been documented.

Gastric Regional Lymph Node Metastases from a Squamous Cell Carcinoma of Unknown Primary Site: A Case Report

Toshiaki Komo, et al.

INTRODUCTION: A cancer of unknown primary site is a malignant tumor for which the primary site is unknown despite a thorough examination, and which has been histologically proven to be a metastatic lesion. Metastases to intraperitoneal and to gastric regional lymph nodes are rare.

A Rare Case of Gastric Aberrant Pancreas Causing Bleeding from a Gastric Ulcer

Tsuyoshi Saito, et al.

INTRODUCTION: An aberrant pancreas is pancreatic tissue lacking anatomical and vascular continuity with the normal pancreas. It typically occurs in the gastrointestinal tract, especially in the stomach, duodenum, and small intestine. Most cases are asymptomatic and discovered incidentally during imaging or surgery. Gastric aberrant pancreas rarely presents with bleeding, making diagnosis and treatment decisions challenging.

Surgical Management of Breast Cancer Adjacent to a Calcified Ventriculoperitoneal Shunt: A Case Report

Hitomi Wake, et al.

INTRODUCTION: Breast cancer arising in tissue adjacent to a ventriculoperitoneal (VP) shunt is exceptionally rare, and there is little guidance on how to manage the shunt hardware during oncologic surgery in such cases.

Mesenteric Steal Syndrome Caused by Abdominal Aortic Stenosis due to Takayasu Arteritis

Shoichiro Nagashima, et al.

INTRODUCTION: Chronic mesenteric ischemia (CMI) is usually caused by atherosclerotic stenosis of multiple mesenteric arteries. However, aortic stenosis secondary to Takayasu arteritis can rarely cause intestinal ischemia through hemodynamic steal from the mesenteric to lower limb circulation.
