Neutrosophic method for the evaluation and control of obstructive abdominal effect due to sigmoid volvulus

Abstract

Volvulus is defined as a twisting of the intestine on itself, which can cause partial or complete obstruction, depending on the degree of torsion. In the context of this research, the aim is to implement a neutrosophic method for the evaluation and control of the obstructive abdomen effect caused by a sigmoid volvulus, a condition that typically occurs in patients with a short mesentery and minimal fixation in the splenic flexure, generally with a 360-degree twist. This intestinal complication is a relatively rare cause of acute abdomen, with a mortality rate that can reach up to 60% in complex cases, being more prevalent in elderly men with limited self-sufficiency. Initial symptoms include an intestinal occlusive picture and nonspecific biochemical alterations, with risks of sepsis or intestinal ischemia in advanced situations. Although the “coffee bean” sign is noticeable on plain radiographs, computed tomography is considered the gold standard for diagnosis. Treatment, which may be temporary or definitive, depends on a timely diagnosis that allows consideration of endoscopic and surgical options; however, in cases of abdominal sepsis and hemodynamic compromise, urgent surgical intervention is required, which presents a higher rate of complications.
