Duplication of the transverse colon in adults: a case report and literature review

Abstract

BackgroundDuplication of the transverse colon is a rare gastrointestinal malformation. Its pathogenesis is still unclear, and it is extremely rare in adults. Patients often present with symptoms of tumor compression such as abdominal mass, abdominal pain, and constipation as the first manifestation.Methods and resultA patient with a duplication of the transverse colon was admitted to the Department of General Surgery of our hospital. Laparoscopic exploration found a mass at the rear of the transverse colon near the splenic flexure, and the root was connected to the middle portion of the transverse colon.ConclusionSurgery is a radical treatment and reduces the possibility of perforation, bleeding, obstruction, and cancer.

Unusual radiological and endoscopic findings of a small intestinal duplication in an adult

“…The typical features of ATD are as follows: on CT or MRI, it manifests as an abnormal cystic or tubular structure adjacent to the digestive tract ( 5 - 25 ), while on endoscopy, it is characterized by a bifurcated or diverticular-like lumen ( 5 - 15 ) or by extrinsic compression of the digestive wall via a bulging mass ( 16 - 25 ). In the minority of ATD cases accompanied by malignancy or inflammation, the presentation may be atypical and diverse and include, for example, irregular thickening of the gastrointestinal wall or a complex soft tissue mass on radiological imaging and luminal stenosis or a cavity-forming mass on endoscopic examination ( 26 - 28 ). In rare instances, ATD may display the “sausage” and “doughnut” signs mimicking intussusception on CT or MRI; meanwhile, it may exhibit an intraluminal protruding structure on endoscopy ( 29 - 32 ) ( Table 1 ), as observed in the case reported here.…”
