“…Radiological imaging studies have an important role in the pre-operative diagnosis. Plain erect abdominal X-rays generally show a dilated sigmoid colon, and a coffee bean-like shape formed by grossly dilated and closely apposed sigmoid loops (17). In a non-gangrenous or nonperforated sigmoid volvulus patient, water soluble contrast enema studies can be used for diagnostic and therapeutic purposes.…”

Objective − The aim of this report is to present the case of a child with a sigmoid volvulus. Sigmoid volvulus in pediatric patients is a rare but potentially life-threatening condition. This condition occurs when a redundant sigmoid loop, with a narrow mesenteric base of attachment to the posterior abdominal wall, rotates around its mesenteric axis.Case Report − A 13-year-old boy presented as an emergency with a 3-day history of back pain and abdominal distention. Plain abdomen X-ray showed dilated large bowel loops in the upper left quadrant. An abdominal computed tomographic scan revealed a bowel obstruction with swirling of the mesentery, which suggested a sigmoid volvulus. The redundant sigmoid colon was hugely dilated, and was resected after detortion and resection. End to end anastomosis was performed.Conclusion − This case report emphasizes the importance of clinicians keeping a sigmoid volvulus in mind as a rare, yet important differential when considering abdominal pain in young, healthy patients.

“…9,27,28 Various forms of volvulus in humans have since been diagnosed with the aid of the CT whirl sign, including stomach, small bowel, large bowel, and splenic volvulus. 18,[21][22][23][29][30][31][32][33][34][35][36][37][38][39] This sign is best appreciated when the imaging plane is perpendicular to the axis of rotation; therefore, multiplanar reconstructions (ie, in transverse, dorsal, and sagittal planes) may be necessary for identification of the whirl. 9,28 Modern multiple detector array CT scanners enable acquisition of images with a notable decrease in slice thickness versus older technology, thus improving spatial resolution so that it is nearly isotropic; high-resolution multiplanar reconstructions are therefore readily produced.…”

In the present report, the CT whirl sign was used to diagnose volvulus of the abdominal viscera, which suggests that this diagnostic indicator has utility in veterinary patients. Mesenteric volvulus with GDV was successfully treated in a nondomestic species. The tooth root abscess, a common condition in macropods, may explain the historic episodes of anorexia reported by the owner and may have contributed to the development of mesenteric volvulus and GDV in this kangaroo.

“…Diagnosis depends upon clinical presentation and radiological findings. Plain erect abdominal x-ray generally shows a dilated sigmoid colon and a coffee bean-like shape formed by grossly dilated and closely apposed sigmoid loops [12]. A whirl sign of the dilated sigmoid loop around mesocolon and a bird-beak appearance may characteristically be seen in CT abdomen [13-14].…”

Introduction: Colonic volvulus is not an uncommon cause of large bowel obstruction. Limited research has been done about colonic volvulus in our part of the world which has been regarded as "volvulus belt." The aim of this study is to evaluate the clinical features, management, and factors affecting perioperative outcomes in patients with colonic volvulus.Methods: A retrospective review of medical records of all patients managed for colonic volvulus in Universal College of Medical Sciences, Bhairahawa from January 2012 to December 2016 was done. Data on patient demographics, clinical course, methods of treatment, and outcomes were analyzed.Results: A total of 62 patients (46 males) were studied. Mean age was 57.9 ± 10.4 years. The most common site involved was sigmoid (85.5%). The diagnosis was made by abdominal x-rays in 39 patients (62.2%), CT scan in 13 patients (21%), and laparotomy in 10 patients (16.1%). Fifty-eight patients (93.5%) were treated surgically. Resection and ostomy was the commonest operation performed in 30 patients (48.7%) followed by resection with anastomosis in 24 patients (38.7%). The overall complication was 38.7%. There were 9.7% of deaths. In multivariate analysis, age ( ≥ 60 years) (odds ratio (OR); 27.0, confidence interval (CI); (1.92-403), P; 0.01), preoperative hypotension (systolic blood pressure <90 mmHg) (OR; 7.82, CI; (1.19-51.2), P; 0.03), and gangrenous bowel (OR; 76.7, CI (3.60-1632), P; 0.005) were significant predictors of postoperative complications .Conclusions: Volvulus of the colon is common in males and constipation is being commonest risk factors for volvulus. Surgeons should have a high index of suspicion and should be aware of these problems to make the early diagnosis with prompt treatment and to ensure better patient outcomes in volvulus endemic areas like ours.
