[A Case Report of Transverse Colon Cancer with Large Abdominal Wall Abscess].

A 65-year-old woman presented to the emergency outpatient department with a chief complaint of left hypochondriac pain and a rapidly expanding tumor mass. Abdominal contrast-enhanced computed tomography(CT)revealed a tumor in the transverse colon and an extensive abdominal wall abscess. A colonoscopy further confirmed a tumor in the transverse colon, and the patient was diagnosed with transverse colon cancer, abdominal wall infiltration, and abdominal wall abscess.

[Conversion Surgery for Unresectable Advanced Gastric Cancer-A Case Report].

Unresectable advanced gastric cancer is associated with poor prognosis. In a few studies, long-term survival was achieved with conversion surgery in patients who responded to chemotherapy. Here, we have reported a case of unresectable advanced gastric cancer in which curative resection was achieved with conversion surgery.

[A Case of Laparoscopic Local Resection of the Stomach for an Inflammatory Myofibroblastic Tumor].

A 52-year-old man underwent upper gastrointestinal endoscopy screening that identified a submucosal tumor in the gastric fornix, and a solid tumor with a maximum diameter of 35mm was suspected based on abdominal computed tomography. An endoscopic ultrasound-guided fine needle aspiration biopsy showed spindle-shaped cells with KIT, CD34, desmin, and S-100 all testing negative. Based on the diagnosis of a gastrointestinal stromal tumor, subtotal gastrectomy was performed laparoscopically.

[A Case Report of Clinical Complete Response with Chemotherapy for Descending Colon Cancer Complicated with Severe Pulmonary Dysfunction].

A 76-year-old male patient was diagnosed with progressive descending colon cancer. Since the patient had severe respiratoryfunction impairment after right pneumonectomy, the anesthesiologydepartment of our hospital determined that general anesthesia induction was too difficult. He was thus started on capecitabine plus oxaliplatin(XELOX)therapy.

Immunonutrition suppresses acute inflammatory responses through modulation of resolvin E1 in patients undergoing major hepatobiliary resection.

Background: Although several studies have reported the effects of immunonutrition on clinical outcomes, detailed mechanisms of immunonutrition after an operation are still unclear. It was recently reported that resolvin E1, a novel lipid mediator generated from eicosapentaenoic acid (EPA), activates factors that reduce inflammation. This randomized clinical trial was designed to investigate not only the effect of immunonutrition on postoperative complications but also the participation of resolvin E1 on anti-inflammatory effects of immunonutrition in patients undergoing major hepatobiliary resection.

[A Case of Multiple Liver Metastases and Peritoneal Dissemination after Resection of a Gastrointestinal Stromal Tumor of the Stomach Successfully Treated with Imatinib Mesylate].

A 71-year-old man was diagnosed with a gastric tumor approximately 50mm in diameter on computed tomography (CT). In January 2000, he underwent a proximal gastrectomy. Pathological examination showed 5 mitoses per 50 high-power fields, while immunohistochemical analysis showed positive staining for KIT.

A case report of undifferentiated carcinoma with osteoclast-like giant cells of the pancreas and literature review.

Osteoclast-like giant cell tumors rarely arise in the pancreas. Here we report the case of a 78-year-old woman who was diagnosed with a well-defined 3 cm multilocular mass in the pancreatic body by the use of ultrasonography, computed tomography and magnetic resonance imaging. The rim and the septa of the tumor were well enhanced.
