Thoracoscopic Congenital Esophageal Stenosis Repair and Thal Fundoplication by Right Thoracic Approach: A Case Report

Kazuya Nagayabu, et al.

INTRODUCTION: Congenital esophageal stenosis (CES) is a rare clinical condition found in 1 in 25000–50000 live births. Surgical treatment is required when endoscopic balloon dilatation is ineffective. Laparoscopic and thoracoscopic approaches are selected based on lesion location. Gastroesophageal reflux (GER) is often observed as a postoperative complication that necessitates additional fundoplication. We report a case of CES in the lower third of the esophagus that was treated with simultaneous thoracoscopic resection and Thal fundoplication using the right thoracic approach.

Adult Cystic Intestinal Duplication of the Ileum Laparoscopically Resected after Preoperative Diagnosis with Cine Magnetic Resonance Imaging and Abdominal Ultrasound: A Case Report

Takashi Takeda, et al.

INTRODUCTION: Small bowel duplication in adults is an uncommon congenital anomaly that often presents with nonspecific symptoms, such as abdominal pain, vomiting, or constipation, which complicates diagnosis. Imaging techniques such as computed tomography (CT) and ultrasonography are commonly used, and cine magnetic resonance imaging (MRI) has emerged as a promising modality for diagnosing duplication cysts by capturing peristaltic movements. Surgical resection is the definitive treatment for preventing complications such as obstruction, infection, or malignant transformation.

Long-Term Survival after Curative Resection for Postoperative Dissemination of Pancreatic Ductal Adenocarcinoma: A Case Report

Yoshitaka Shimamaki, et al.

INTRODUCTION: Pancreatic ductal adenocarcinoma (PDAC) has a very poor prognosis and high mortality. The prognosis for recurrence after surgery is extremely poor. Resection for disseminations of PDAC is not recommended.

Sclerosing Angiomatoid Nodular Transformation of the Laparoscopically Resected Spleen: Case Reports and Review of the Literature

Shingo Yamasaki, et al.

INTRODUCTION: Most splenic tumors are benign; however, it is essential to differentiate them from malignant tumors, such as malignant lymphoma and metastatic tumors. Sclerosing angiomatoid nodular transformation (SANT) is a relatively rare benign tumor that has been reported recently. Splenectomy is performed in most cases of SANT because of the challenges associated with a definitive diagnosis.

A Large Gastrointestinal Stromal Tumor under the Disguise of a Gastric Diverticulum: Report of a Case and Review of the Literature

Vasileios I. Lagopoulos, et al.

INTRODUCTION: Gastrointestinal stromal tumors (GISTs) are a relatively rare clinical entity. They usually appear as solid masses in numerous locations throughout the gastrointestinal tract, varying in size and typically exhibiting extraluminal expansion along with a range of nonspecific symptoms. The exophytic growth pattern of these tumors may occasionally complicate the differential diagnosis from other medical conditions with similar clinical and imaging findings.

A Chest Wall Myofibroma in an Adult

Yasuaki Kubouchi, et al.

INTRODUCTION: Myofibroma is a rare benign tumor that often involves the skin, subcutaneous tissue, and/or bone in the head and neck, typically developing in children. Adult cases, particularly in the chest wall, are extremely rare.

A Catheter-Guided Technique for Second Branchial Cleft Fistula Excision in Infants: A Case Report

Akio Kawami, et al.

INTRODUCTION: Second branchial cleft (SBC) fistulas are the most common branchial cleft anomalies and typically present in infancy or early childhood. While complete surgical excision is the standard treatment, surgical challenges in younger children arise because of narrower fistula tracts and inadequate visualization, which increase the risk of complications and recurrence.

Laparoscopic Cholecystectomy for a Patient after Percutaneous Endoscopic Gastrostomy due to Myotonic Dystrophy: A Case Report and Literature Review

Kei Naito, et al.

INTRODUCTION: Percutaneous endoscopic gastrostomy (PEG) is commonly performed for enteral nutrition in patients with various diseases. However, there are few reports on abdominal surgeries for patients after PEG, and the tips for these procedures have not been established. Specifically, in laparoscopic surgeries of the upper abdomen, a gastrostomy can interfere with the surgical field. In addition, perioperative management of concomitant diseases that require PEG placement, including neuromuscular disorders, is required.

Adenocarcinoma with Enteroblastic Differentiation and Neuroendocrine Features in Autoimmune Gastritis: Novel Insights into Tumor Development from Endocrine Cell Micronests

Hidetoshi Satomi, et al.

Autoimmune gastritis leads to fundic gland atrophy and compensatory endocrine cell hyperplasia.1) Enterochromaffin-like (ECL) cell proliferation induces the formation of endocrine cell micronests, with nodular aggregates ≥500 µm considered neoplastic.2) Here, we present a rare case of adenocarcinoma with enteroblastic differentiation (ACED) exhibiting neuroendocrine features in the context of autoimmune gastritis. Despite the poorly differentiated histology, which typically necessitates surgical resection, careful endoscopic assessment and precise technique achieved complete resection with negative margins.

Salvage Right Ventricular Outflow Tract Reconstruction for Pulmonary Embolization with Pulmonary Artery Sarcoma

Tsubasa Nagai, et al.

INTRODUCTION: Pulmonary artery intimal sarcoma (PAIS) is extremely rare and highly malignant. Although improved outcomes have been reported after complete surgical resection and chemotherapy, limited information is available regarding the indications, procedures, and prognosis of palliative surgery for PAIS. This report describes a successful salvage surgical case for rapid hemodynamic deterioration due to PAIS obstructing the pulmonary artery trunk.

Pneumatocele Development after Deceased-Donor Liver Transplantation for Multiple Hepatic Cysts due to Autosomal Dominant Polycystic Kidney Disease: A Case Report

Atsushi Yoshiyama, et al.

INTRODUCTION: A pneumatocele is a cystic change in the lung that can develop as a sequelae of infection, inflammation, positive-pressure ventilation, thoracic trauma, and rarely after lung resection. Pneumatocele development triggered by an extrathoracic etiology is rare. Herein, we report a case of a pneumatocele that developed after a deceased-donor liver transplantation.

Two Cases of Single-Incision Laparoscopic Surgery for Sigmoid Colon and Rectal Cancer in Situs Inversus Totalis

Mamoru Miyasaka, et al.

INTRODUCTION: Situs inversus totalis (SIT) is a rare congenital disorder characterized by the complete inverted transposition of the thoracic and abdominal viscera. This anatomical variation complicates laparoscopic surgery, and there are currently no reports of single-incision laparoscopic surgery (SILS) for patients with sigmoid colon cancer or rectal cancer with SIT.
