IntrOductIOnSigmoid volvulus is considered to be one of the leading causes of acute intestinal obstruction. This could be related to sigmoid colon being a mobile loop which normally lies in the lesser pelvis, but its length and form are the most variable of all colonic segments [1]. It is usually completely invested in peritoneum and is attached to the lower posterior abdominal wall by the fan-shaped sigmoid mesocolon [2]. The position and shape of the sigmoid colon varies according to the length of the colon; the length and mobility of its mesocolon; the degree of distension; the condition of the neighbouring viscera like rectum, bladder and uterus. Studies have shown that variation in the shape of mesocolon could alter the morphology of sigmoid colon [3]. In addition, the length and diameter of the sigmoid colon was found to vary in both genders [4,5] and noted to increase with age [6]. The present study aims to find the morphology of sigmoid colon in South Indian population using cadavers in view of the high incidence of sigmoid volvulus in cases of intestinal obstruction. MAterIAls And MethOdsApproval of the Institutional review board and ethics committee was obtained for the study. Thirty one cadavers donated to the Department of Anatomy for the purpose of teaching and research during the years 2012 to 2014 were evaluated. Cadavers with normal colons without any colonic disease were included in the study. The exclusion criteria were: 1) laparotomy incisions found on cadavers that indicated surgeries in life; 2) diseased or injured sigmoid colon; 3) intra-abdominal pathology such as peritonitis, stricture or adhesions. The age and gender of the cadavers were noted.The sigmoid colon was classified into three main types, classical, long-narrow and long-broad types as described by Madiba and Aim: The aim of this study was to find the morphology of sigmoid colon in South Indian population using cadavers.

“…The classical sign of an acute sigmoid volvulus in plain X-rays is the “coffee bean sign”, while in an abdominal CT scan, the characteristic “whirl sign” as well as an dilated colon with air/fluid level can be detected [11, 12]. Those radiologic findings are due to the torsion of the often long and redundant sigmoid colon around its elongated mesenteric axis what finally causes intestinal obstruction [13]. …”

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. A consequent CT scan of the abdomen revealed a deep outlet obstruction with massively dilated, elongated and twisted loop of the sigmoid colon and no signs of perforation. We performed emergency colonoscopy under the assumption of an acute sigmoid volvulus. After careful insertion of the endoscope completely refraining from insufflation of air or CO₂, endoscopic reposition of the sigma could be achieved and a colonic drainage was placed over an inserted guide wire up to the proximal transverse colon. No relapse occurred and a diagnostic colonoscopy after 4 weeks revealed no tumor or polyps. Our report describes a classic case of acute sigmoid volvulus and undermines the potential of colonoscopy as conservative primary treatment of choice.

The length of the large intestine in children determined by computed tomography scan

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 deidentified 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). The length of the large bowel increased from a mean of 52 cm in children aged <2 years to 73 cm at 4-6 years and 95 cm at 9-11 years. In all age groups, the transverse colon was the longest segment, contributing ∼30% of the total length of the large bowel. In comparison to total large bowel length, the mean proportional length of the rectum (9-12%), sigmoid colon (23-27%), descending colon (19-22%), transverse colon (27-32%), and ascending colon (14-17%) varied little between the three age groups. There were no significant differences between males and females in all age groups. The cecum was located in the right upper quadrant in 27% of children aged 0-2 years but in the right lower quadrant in all 9-11 year olds. These data provide useful information on the length of the large intestine and its component parts in living children, which are particularly relevant to pediatric colonoscopy and surgery. Clin.
