Pre-omental epigastric redundant sigmoid colon: a case report and review of its functional and clinical implications

Introduction The sigmoid colon is continuous with the descending colon proximally and the rectum distally. It is an intraperitoneal organ suspended in a long mesocolon and has a median length of about 25-38 cm. It is highly mobile and quite variable in position and length [1, 2]. A longer than normal sigmoid colon is referred to as a redundant sigmoid colon or dolichosigmoid. Most of these variations are strongly associated with abdominal conditions such as chronic constipation and colicky pains [3]. Anatomically these variants occupy the pelvic cavity or the lower part of the abdomen [1, 4, 5]. A sigmoid colon extending into the upper abdomen is rare. In the present paper we report a case of the sigmoid colonic loop which reached as high as the epigastrium. We also discuss possible functional and clinical implications of this rare finding.
