The CT images revealed variations in the anatomic positions of the
descending colon and sigmoid colon as well as sigmoid diverticulitis.
The locations of anastomoses were stratified by location in rectum and location in colon (including locations in ascending, transverse, and
descending colon).
Categorization of CRC according to the various segments of colon showed that the frequency of rectosigmoid tumor was higher (54.7%), as compared to other CRC tumor types like ascending colon/cecum (25.97%),
descending colon (5.52%), and transverse colon (6%).
Inflammatory changes were also present in the left paracolic gutter with wall thickening and enhancement of the short segment of
descending colon surrounded by a small amount of free fluid.
[7] report a 38-year old woman who survived cardiac arrest following prolonged CPR but had ischaemia and necrosis of the colon, requiring subtotal colectomy of the ascending, transverse and
descending colon. Pathological examination excluded arterial thrombosis as the cause.
His hospital file reads that pellets pierced his wall of gut, jejunum, transverse colon and
descending colon. He had three pellets in jejunum, it read.
CT of the abdomen and pelvis (Figure 1) revealed a 6.7cm cystic mass in the mesentery of the
descending colon that was not present on previous CT six months prior.
Nine cases located in ascending colon 6 in transverse colon and two cases in
descending colon. Size of large bowel lipomas ranged 2-3.5 cm.
Nonetheless, a CT scan of the thorax, abdomen, and pelvis was performed with oral contrast, which showed air within the mediastinum, retroperitoneum, and peritoneal cavity, with a focal collection of contrast adjacent to the
descending colon (Fig.
Hyperplastic polyps are found mostly in the
descending colon and rectum, are usually less than five millimetres across and are very rarely malignant (Mayo Clinic, 2011a).
Site of colorectal obstruction was rectosigmoid in 5 patients,
descending colon in 2, splenic flexure in 1, transverse colon in 1, and ascending colon in 1.
