Sigmoid Colon Cancer Masked by Refractory Diverticulitis With Abscess.

Colorectal cancer (CRC) can occasionally coexist with diverticulitis, thereby complicating diagnosis and treatment. In cases of refractory diverticulitis, it is important to consider the possibility of malignancy and determine appropriate treatment strategies. An 85-year-old male presented with lower left abdominal pain; he was admitted for further examination and the treatment of suspected sigmoid diverticulitis.

Surgical Resection of Remnant Gastric Cancer Following Distal Gastrectomy: A Retrospective Clinicopathological Study.

Background: Remnant gastric cancer (RGC) is one of the less prevalent gastric cancers. The purpose of this study was to explore the clinicopathological characteristics and results of the operation of RGC following distal gastrectomy. In particular, we examined factors related to prognosis.

Sentinel node mapping in adenocarcinoma of the esophagogastric junction.

Background: The incidence of adenocarcinoma of the esophagogastric junction (AEG) is increasing, but the surgical strategy for AEG remains controversial. We hypothesized that sentinel node (SN) mapping for AEG could be validated to avoid unnecessary lymphadenectomy and permit minimally invasive surgery. We examined the feasibility of SN mapping for AEG.

Optimal surgical management for esophagogastric junction carcinoma.

Objectives: Esophagogastric junction carcinoma incidence is increasing worldwide. However, surgical strategies for this cancer remain controversial. This study aimed to clarify the optimal surgical strategy for esophagogastric junction carcinoma.

Octreotide acetate enables the administration of chemoradiotherapy, including the oral anticancer drug S-1, in gastric cancer patients with malignant gastrointestinal obstruction.

Advanced gastric cancer frequently results in the inability to ingest food or drink orally, a condition called malignant gastrointestinal obstruction (MGO). MGO is clinically defined as a gastrointestinal outlet obstruction caused by a large tumor, or malignant bowel obstruction with peritoneal dissemination. MGO impacts the quality of life by interfering with oral intake and by causing gastrointestinal symptoms, such as nausea, vomiting and abdominal pain.

Octreotide acetate successfully treated a bowel obstruction caused by peritoneally disseminated gastric cancer, thereby enabling the subsequent use of oral S-1 chemotherapy.

A 68-year-old woman presented with severe bowel obstruction and was subsequently diagnosed with stage IV gastric cancer with peritoneal dissemination. She was immediately stabilized in the hospital with the placement of a nasointestinal tube. Abdominal computed tomography showed multiple intraperitoneal nodules consistent with peritoneal dissemination of the gastric cancer.

The effects of immediate enteral feeding with a formula containing high levels of omega-3 fatty acids in patients after surgery for esophageal cancer.

Background: We investigated whether supplementation of enteral nutrition (EN) with omega-3 polyunsaturated acids (PUFAs) affected platelet aggregation, coagulation activity, and inflammatory response in the early stages after esophageal cancer surgery.

Methods: Twenty-eight patients with esophageal cancer who underwent the same surgical procedure were selected for this study. All patients received EN, which was started immediately after the operation and was increased to a maximum volume of 1500 ml/day by the third postoperative day (POD).
