Complex S10+S7b Segmentectomy by Pulmonary Ligament Approach Based on B7 Branching Pattern

Yukitaka Sato, et al.

INTRODUCTION: Based on the results of the JCOG0802 study, segmentectomy is now considered the standard treatment for early-stage lung cancer. However, segmentectomy for right basal segment lesions remains technically challenging because of the complexity of B7 branching. B7 demonstrates 3 distinct branching patterns based on its anatomical relationship with the basal vein (BV): ventral, bilateral, and dorsal. Herein, we report a successful S10+S7b complex segmentectomy for S10 lung cancer with a bilateral B7 branching pattern using a pulmonary ligament (PL) approach.

A Case of Pediatric Pancreatic Insulinoma Diagnosed 4 Years after the Onset

Takazumi Kato, et al.

INTRODUCTION: Insulinomas are rare tumors resulting in hyperinsulinemic hypoglycemia. Insulinomas are usually seen in adults, and are very rare in the pediatric population. A total of 10% of insulinomas that occur are associated with multiple endocrine neoplasia type 1, and overall, 10% are malignant.

Laparoscopic Cholecystectomy Using Indocyanine Green Fluorescence Imaging in a Patient with a Type I Accessory Hepatic Duct (Hisatsugu Classification): A Case Report

Kohei Oyamada et al.

INTRODUCTION: Bile duct injury is a rare but serious complication of laparoscopic cholecystectomy (LC), particularly in patients with biliary anomalies such as accessory hepatic ducts (AHDs). Indocyanine green (ICG) fluorescence imaging has recently been recognized as a valuable tool for intraoperative visualization of biliary anatomy. However, its application in Type I AHDs, as classified by Hisatsugu, has not been previously reported.

Simultaneous Gastric Cancer Metastases to the Small and Large Intestines: Hidden Small Intestinal Lesions and Colonic-Mimicking Metastases

Sota Nakamura et al.

INTRODUCTION: Gastric cancer often presents with metastases at diagnosis, but simultaneous metastases to both the small and large intestines are extremely rare and may be misinterpreted as synchronous primary intestinal cancers, particularly when preoperative imaging is inconclusive.

Recent Treatment Options for Primary Colonic Leiomyosarcoma: A Case Report and a Review of the Literature

Akira Dejima, et al.

INTRODUCTION: Primary colonic leiomyosarcoma (LMS) accounts for only 0.12% of colonic malignancies. However, it is highly aggressive and associated with a poor prognosis. While radical surgical resection is considered the mainstay of treatment, the optimal surgical approach and the role of adjuvant chemotherapy remain unclear due to the small number of reported cases.

Temporary Occlusion of Patent Ductus Arteriosus in Adult during Cardiac Surgery

Koki Ikemoto, et al.

INTRODUCTION: Patent ductus arteriosus in adults is rare, and is commonly recommended to be closed due to the possibility of cardiac complications. Patent ductus arteriosus closure has been often performed using endovascular devices or patches. However, the use of these closure devices in the presence of active infection is controversial, and patch closure procedure along with other cardiac surgery could make it more complicated. We report a case in which we successfully treated infective endocarditis with temporary occlusion of a patent ductus arteriosus in an 80-year-old woman.

A Neonatal Case of Paraesophageal Mixed Hiatal Hernia Detected by “Coiled-Up Sign”

Yoshiki Yamaguchi, et al.

INTRODUCTION: Paraesophageal mixed hiatal hernia is a rare entity in neonates, that occasionally induces near-complete esophageal or gastric obstruction, and its diagnosis is sometimes difficult. Furthermore, its management remains controversial. This case provides new insights into the diagnosis and treatment strategies of neonatal paraesophageal mixed hiatal hernias.

A Cystic Variant of Acinar Cell Carcinoma of the Pancreas with Repeated Bleeding from a Pseudoaneurysm: A Case Report

Kazue Morishima, et al.

INTRODUCTION: Acinar cell carcinomas are rare pancreatic neoplasms, accounting for approximately 1% of all exocrine pancreatic tumors. We describe a case of a cystic variant with intracystic hemorrhaging that was difficult to differentiate from a pseudocyst due to its morphology.

A Case of Chronic Expanding Hematoma Presenting as a Subcutaneous Mass 24 Years after Konno Procedure

Yoshinobu Watabe, et al.

INTRODUCTION: Here, we report a very rare case of chronic expanding hematoma presenting as a gradually enlarging subcutaneous pulsatile mass detected 24 years after a Konno procedure.

Surgical Management of a Rare Inguinal Intestinal-Cutaneous Fistula with an Incarcerated Richter’s Femoral Hernia: A Case Report

Saho Aso, et al.

INTRODUCTION: Richter’s hernia is a rare type of hernia in which only a part of the intestinal wall becomes entrapped, often leading to ischemia and necrosis. In rare cases, it can result in spontaneous formation of an intestinal-cutaneous fistula. Herein, we report a rare case of an intestinal-cutaneous fistula caused by incarceration of a Richter’s femoral hernia. Additionally, we present a brief literature review to highlight the diagnostic and therapeutic challenges associated with this condition.

A Case of Sandwich Repair for Posterior Ventricular Septal Rupture through the Right Atrium

Shunsuke Nakata, et al.

INTRODUCTION: We encountered a case in whom ventricular septal rupture (VSR) repair was performed only through right atriotomy. A few cases of VSR repair using the right atrial approach have been reported in the literature. We report our experiences with focusing on the surgical technique.

Successful Management of Obstructive Fibrinous Tracheal Pseudomembrane with a Coring Technique after Preoxygenation with a High-Flow Nasal Cannula: A Case Report

Takafumi Iguchi, et al.

INTRODUCTION: Obstructive fibrinous tracheal pseudomembrane, an extremely rare but potentially fatal complication of tracheal intubation, occurs several days after intubation and is characterized by central airway obstruction due to the formation of a fibrinous pseudomembrane. Early diagnosis is crucial. Treatment typically involves bronchoscopic removal of the pseudomembrane. Herein, we describe a patient whose pseudomembrane was successfully cored out using fiberoptic intubation after achieving preoxygenation with high-flow nasal cannula oxygen therapy.
