[A Case of Rhabdomyolysis Caused by Oxaliplatin during Postoperative Adjuvant Chemotherapy].

The patient was a 50-year-old male. At the age of 48 years, he had undergone total gastrectomy and right hemicolectomy simultaneously for gastric and ascending colon cancers. Since adjuvant chemotherapy has become common practice for patients with ascending colon cancer, capecitabine was administered for 6 months.

[A Case of Transverse Colon Cancer Complicated by Eosinophilic Granulomatosis with Polyangiitis].

A man in his 50s had undergone steroid therapy for eosinophilic granulomatosis with polyangiitis(EGPA). Since an examination for malignant tumors revealed type 0-Ⅰsp(cT1aN0M0)and type 2(cT2N0M0)lesions in the proximal and mid- transverse colon, respectively, he was referred to our department. Endoscopic resection was performed on the proximal lesion.

[A Case of Extramural Growth-Type Ileocecal Colon Cancer].

A woman in her 80s was diagnosed with an abdominal mass during physical examination. Contrast-enhanced computed tomography(CT)revealed a tumor with contrast enhancement outside the ileocecal region of the intestine, and the ileocolic artery penetrated the tumor. No tumor was detected by colonoscopy.

Usefulness of a Precursory Small Epigastric Midline Incision during Laparoscopic Right Hemicolectomy.

Objectives: During laparoscopic right hemicolectomy, many surgeons make a small incision near the umbilicus after the routine intraperitoneal operation. In this study, we created a precursory small epigastric incision at the center of a line connecting the xiphoid process and umbilicus (the M point, an empirically determined position) at the start of surgery prior to laparoscopic manipulation. This study aimed to determine whether the small incision at the center of the M point was a suitable position through which the right hemicolon is extracted.
