INTRODUCTION Mesenteric panniculitis of the sigmoid colon is a rare occurrence in surgical practice. The aim of this article is to present a case of mesenteric panniculitis of the sigmoid colon and a short review of the literature. CASE PRESENTATION We reviewed the hospital record of a 63-year-old man who presented with a palpable mass in the left abdomen and clinical signs of a partial bowel...

This paper presents performance analysis of the Evolutionary Programming-Artificial Neural Network (EPANN) based technique to optimize the architecture and training parameters of a one-hidden layer feedforward ANN model for the prediction of energy output from a grid connected photovoltaic system. The ANN utilizes solar radiation and ambient temperature as its inputs while the output is the tot...

An 89-year-old woman presented to our emergency department (ED) with a 4-day history of abdominal pain and vomiting. The physical exam revealed hypotension and a distended abdomen with generalized tenderness. Laboratory studies revealed hyperkalemia and elevated creatinine, lactate, and troponin. Given her hemodynamic instability, an emergent noncontrast abdominal computed tomography (CT) was o...

Objective : The aim of this study was to report the result of surgical treatment of volvulus of the sigmoid colon by colectomy in 2 phases.Material and methods: This is a descriptive and retrospective study during 5 years, led in the unit of digestive and general surgery of Aristide le Dantec Teaching Hospital (Dakar-Senegal). The criterion of inclusion was volvulus of the sigmoid colon treated...

An 88-year-old woman experienced fever, chills, and severe left abdominal pain for 1 day. She had a history of chronic constipation and was bedridden. Non-enhanced abdominal computed tomography (CT) showed wall thickening of the descending colon, a 2-cm wall defect, pericolonic stranding, fecal material outside the colonic lumen, and pneumoperitoneum, and stercoral perforation of the descending...

BACKGROUND AND AIMS The pathogenesis of asymptomatic diverticular disease (ADD) and symptomatic uncomplicated diverticular disease (SUDD) has not been elucidated. The aim of our study was to assess whether altered visceral perception or abnormal compliance of the colorectal wall play a role in these clinical entities. METHODS Ten ADD patients, 11 SUDD patients, and nine healthy controls were ...

BACKGROUND Many reports have described sigmoid volvulus, but fatal hemorrhagic shock resulting from the rupture of the involved artery has not been reported as a complication of a sigmoid volvulus. CASE REPORT A 71-year-old man with slight abdominal pain and obstipation in hypotension died at a nursing home without seeing a doctor. At autopsy, a mesenteric hematoma and hemoperitoneum was obse...

Sigmoid colon diverticulosis is commonly seen in both the surgical outpatient and emergency departments. Rarely, these sigmoid diverticulum, which usually range from 2– 3mm to 2cm in size, can enlarge to more than 10 times. This is due to a ball-valve type mechanism that traps colonic gas inside the sigmoid diverticulum causing it to gradually enlarge. Patients with a giant sigmoid diverticulum...

Intraluminal pressures were measured with four open ended, water perfused tubes in the fasting state and after a standard liquid meal (400 KCal, 375 ml, protein 15 g, carbohydrate 55 g, lipid 13.4 g) in six patients with sigmoid diverticular disease, 20 with the irritable bowel syndrome and in 13 controls. The pressure sensors were positioned in the true sigmoid colon at colonoscopy at 25, 35, ...
