[Curative Resection after Chemotherapy for Advanced Extensive Cholangiocarcinoma-A Case Report].

A 73-year-old, male patient presented with the chief complaint of epigastric pain and received the diagnosis of extensive cholangiocarcinoma after a close examination. Extensive extension of the malignancy into the right and left hepatic ducts precluded a curative resection, and the patient received GC therapy. After 11 courses of GC over about 1 year, no new lesions or tumor progression was observed, and a bile duct mapping biopsy was performed to investigate the possibility of resection conversion.

Robotically assisted total gastrectomy for lymphadenopathy after long-term follow-up for multiple type 1 gastric neuroendocrine tumor (NET): a case report.

Background: Type 1 gastric neuroendrine tumor (NET) is usually associated with chronic atrophic gastritis and forms multiple lesions. While most cases of type 1 gastric NET are generally slowly growing, some develop regional lymph node metastases even after long-term dormancy.

Case Presentation: A 73-year-old male patient with a 32-year history of multiple gastric NET was being followed-up at the study center after endoscopic submucosal dissection (ESD) of a large gastric NET.

Acquired diaphragmatic hernia following a peritoneal biopsy for gastric cancer dissemination in the diaphragm: a case report.

Background: Acute diaphragmatic hernia is a life-threatening condition caused by prolapse of an abdominal organ into the thoracic cavity through a defect in the diaphragm. We present herein a case of acquired diaphragmatic hernia following a peritoneal biopsy for gastric cancer dissemination in the diaphragm.

Case Presentation: A 72-year-old, female patient presented with a complaint of acute abdomen 10 months after receiving a diagnosis of stage IV gastric cancer with peritoneal dissemination based on peritoneal biopsy findings during staging laparoscopy.

Robotic distal gastrectomy with D2 lymphadenectomy for advanced gastric cancer with celiac-arterial anomaly (Adachi type VI, group 26): Case report.

In gastric cancer surgery, some celiac-arterial anomalies are associated with a risk of anatomical misidentification and insufficient lymphadenectomy. We herein report a case of successful robotic distal gastrectomy with D2 lymphadenectomy based on preoperative, anatomical recognition using three-dimensional computed tomography (3D-CT) in a patient with advanced gastric cancer and a rare anomaly of the celiac artery. A 64-year-old, male patient was referred to our division with a diagnosis of advanced gastric cancer.

Robot-assisted completion gastrectomy preserving interposed jejunum in remnant gastric cancer following a proximal gastrectomy reconstructed by jejunal interposition: A case report.

Minimally invasive completion gastrectomy is technically demanding and comprises a variety of procedures depending on the previous operation. We present herein a case of robot-assisted completion gastrectomy preserving the interposed jejunum in remnant gastric cancer following a proximal gastrectomy reconstructed by jejunal interposition. A 76-year-old, male patient experienced newly developed stage cT1bN0M0 gastric cancer in the distal remnant stomach 5 years after his initial proximal gastrectomy.
