INTRODUCTION: Intestinal malrotation is a congenital anomaly, and its occurrence in adults is rare. Colon cancer with intestinal malrotation is far more rare. We herein report two cases of colon cancer with intestinal malrotation treated with laparoscopic surgery and reviewed the literatures in Japan. PRESENTATION OF CASES: Case 1 involved a 78-year-old man. Abdominal enhanced computed tomography (CT) showed that the tumor was located in the sigmoid colon. Intraoperatively, the cecum and ascending colon were located along the midline and the small intestine occupied the right side of the abdomen...

Squamous cell carcinoma (SCC) of the rectum is a rare clinical entity with an incidence rate of 0.1-0.25% per 1,000 cases. Though its etiology and pathogenesis remains unclear, it has been associated with chronic inflammation and infections. Herein, we report a case of an 82-year-old female who presented with a 2-month history of worsening abdominal pain, hematochezia, and bilateral inguinal lymphadenopathy with right-sided purulent discharge. Two years prior, she had had an unremarkable screening colonoscopy which met all quality indicators...

The month of March is dedicated to Colon Cancer Awareness. Worldwide, colorectal cancer (CRC) incidence has been on the rise. It is currently the third most common cancer in men (746,000 cases, 10.0% of the total) and the second in women (614,000 cases, 9.2% of the total).1 Arecent meta-analysis reported a 61% risk reduction in CRC incidence with colonoscopy.2 Unlike screening programs for breast and prostate cancers, not only has CRC screening reduced mortality from colon cancer and detected early CRC, it has also decreased the incidence of CRC through detection and removal of pre-cancerous lesions...

Follow-up and surveillance form an important aspect of care in patients with colorectal cancers (CRC). Most recurrences will occur within 2 years of surgery and 90% by 5 years. Follow up protocols have not been well defined in stage I disease and the approach should be individualized. As 40% of patients with stages II and III will develop recurrences, intensive postoperative follow-up strategy is recommended for them. It includes visit to the clinician for clinical examination, serum carcinoembryonic antigen (CEA), computed tomography (CT) of the chest and abdomen, colonoscopy, and flexible proctosigmoidoscopy in rectal cancers...

A 61-year-old man with previous history of lung adenocarcinoma underwent 2 F-FDG PET/CT investigations. The first for assessment of enlarged mediastinal lymph nodes revealed an area of increased FDG uptake in the sigmoid colon (located at the right pelvis). Colonoscopy showed a segmental area of ischemic sigmoid colitis, confirmed on histology postbiopsy. The asymptomatic man had no risk factors, and no specific treatment was administered, apart from supportive measures. One year later, there was no significantly abnormal uptake on PET/CT...

Little information is available on the length of the normal large intestine and its component parts in children. This information would be useful for procedures such as colonoscopy. The aim of this study was to investigate the length of the large intestine and its component parts in New Zealand children. Archival de-identified pediatric supine abdominopelvic computed tomography (CT) scans were retrospectively analyzed. After exclusion criteria, a total of 112 scans (57 males and 55 females) were included in the study and divided into three age groups: 0-2 years (n=33), 4-6 years (n=40), and 9-11 years of age (n=39)...

An acute sigmoid volvulus is due to the torsion of the sigmoid colon around its mesenteric axis. It mainly occurs in elderly patients and represents an abdominal emergency requiring urgent treatment. A 53-year-old male patient with severe craniocerebral injury and traumatic subarachnoidal bleeding 3 weeks prior presented on the ward with distended abdomen without abdominal pain, muscular defense, or resistances. He featured large volume diarrhea within the last few hours without signs of bleeding. A plain abdominal X-ray demonstrated a coffee bean sign indicating a sigmoid volvulus...
