[A Case of Signet-Ring Cell Carcinoma of the Ampulla of Vater in a Young Male].

A male in his twentieth was referred to our hospital for jaundice. Computed tomography(CT)showed dilation of the intrahepatic and extrahepatic bile ducts and showed a lesion at the ampulla of Vater, which caused obstructive jaundice. Upper gastrointestinal endoscopy revealed a tumor of protruded-predominant type with raised margins at the ampulla of Vater, and biopsy from the lesion indicated malignancy.

[Robot Assisted Lower Anterior Resection for Anastomotic Recurrence of Colorectal Cancer-A Case Report].

Patient undergoing R0 resection have the good survival advantage following surgery for recurrent rectal cancer. Robotic surgery for anastomotic local recurrence of rectal cancer has never been reported before. An 80-year-old woman who had undergone high anterior resection for rectal cancer 1 years previously got colonoscopy.

[A Case of Metastasis to the Pancreas from Colorectal Cancer Which Was Difficult to Distinguish from Primary Pancreatic Cancer].

A man in his 50s underwent laparoscopic sigmoid colectomy for sigmoid colon cancer with liver metastasis(cT4aN1M1a, cStage Ⅳa), followed by partial liver resection(S4, S6). One and a half years after the initial surgery, CEA and CA19-9 increased, and contrast-enhanced CT and MRI showed a hypovascular lesion with dilation of the distal pancreatic duct in the pancreatic body. Adenocarcinoma was detected by brushing cytology of the lesion and pancreatic juice cytology by ERCP.

[Risk Factors for Recurrence in Patients with Pathological Stage Ⅱ Colorectal Cancer].

Background: The risk factors for recurrence in patients with pStage Ⅱ colorectal cancer still remains controversial. The aim of this study was to investigate the risk factors for recurrence after surgery in patients with pStage Ⅱ colorectal cancer.

Method: We retrospectively reviewed 311 patients with primary pStage Ⅱ colorectal cancer who underwent radical resection without neoadjuvant therapy at our institute between January 2014 and December 2019.

Intra-abdominal desmoid-type fibromatosis successfully resected using laparoscopic fluorescence imaging with indocyanine green after intersphincteric resection for rectal cancer.

Successful resection of intra-abdominal tumors using indocyanine green (ICG) fluorescence imaging has not been reported. Here, we report a rare case of an intra-abdominal desmoid-type fibromatosis successfully resected using this technique after intersphincteric resection (ISR) for rectal cancer. One year after ISR for rectal cancer in a 47-year-old man, computed tomography showed a 50-mm intra-abdominal tumor near the left common iliac vein.

Successful redo aortic valve replacement using Perceval valve in a patient with prosthetic valve endocarditis complicated by acute cerebral infarction.

Introduction: and importance: For treatment of prosthetic valve endocarditis (PVE), redo-aortic valve replacement (AVR) is usually required. However, the recurrence of PVE continues to be a serious problem that needs a solution.

Case Presentation: An 83-year-old woman who had undergone AVR for aortic infective endocarditis 12 years ago was diagnosed with PVE complicated with acute cerebral infarction.
