ABSTRACT

This study investigated the clinical picture of gangrenous sigmoid volvulus presented by Indian patients to describe the various patterns of gangrene and to identify the risk factors leading to the very high mortality from this disease.
A structured protocol including nine parameters was used to study risk factors in 76 patients treated at two major teaching hospitals in India. The clinical picture of patients at the two hospitals did not differ significantly.
Contrary to expectations, we found gangrene in 26% of cases extending beyond the area of constriction into the rectum/descending colon. This extension was sometimes patchy and had an ill defined line of demarcation, which may lead to an error in judgment and cause a failure of anastomosis, which can be fatal. Risk factors were age over 60 years, the presence of shock on admission and a history of previous episodes of volvulus.
This study identified three risks for survival. It is suggested that all patients with nongangrenous sigmoid volvulus undergo a recurrence-prevention procedure immediately or electively. We also found that extension of gangrene beyond the confines of the constriction is not uncommon, calling for caution on the part of the treating surgeon.

    • "Bhatnagar[14], les facteurs de risque de mortalité sont : l'âge plus de 60 ans, la présence d'un choc à l'admission et la présence d'un épisode antérieur de volvulus. Pour d'autres auteurs, la mortalité périopératoire est fonction de la durée d'évolution des symptômes, de l'état général du patient mais aussi de la vitalité de l'anse tordue et du geste chirurgical pra- tiqué[23,24].

    ABSTRACT: Background and Objective: Cases presenting with intestinal perforation and obstruction constitute a substantial work load on our surgical service. Etiologies vary in underdeveloped and developed countries. Histopathological examination of resected intestine is expected to provide the definite evidence of the underlying etiology- guiding a better health care planning for preventive measures. Our objective was to study the spectrum of histopathological findings in resected intestines from cases of intestinal obstruction and perforation in our local population to document the underlying etiology. Methods: A total of 120 cases of intestinal resection were included. Detailed gross and microscopic examination with routine stains was performed. Definite evidence of any specific etiology on the basis of morphology was documented. Results: A total of 95 cases with clinical/radiological diagnosis of obstruction (79.2%) and 25 of intestinal, perforation (20.8%) were included. Tuberculous enteritis was the commonest etiology (n=41; 43.1%) in cases of intestinal obstruction followed by malignant tumours (n=30; 31.5%). ischemic infarct/gangrene, post op illeal adhesions, polyps and ulcerative colitis followed. In cases of perforation, Typhoid enteritis (n=15; 60%), was the commonest pathology followed by idiopathic perforation (n=5; 20%), tuberculous enteritis (n=3;12%), carcinoma (4%) and ulcerative coliti (4%). Conclusion : In developing countries infective etiology remains a dominant cause of intestinal obstruction and perforation. Its presentation in younger age leading to intestinal resection demands effective preventive measures in this part of the world to prevent morbidity and mortality.

    • "The predominant symptom of gangrenous sigmoid volvulus is abdominal pain and progressive abdominal distension (92 to 95%), constipation (92%), muscle guarding / rigidity (75%) and vomiting in 60% of the cases (Asbun 1992, Bagarani 1993, Bhatnagar 2004, Oren 2007, Pahlman 1989). A visible sigmoid loop is noted in 42% and rectal examination may reveal blood in the examination finger. "
