Sigmoid diverticulitis is a complication of colonic diverticulosis, and one the presentations diverticular disease. It very common pathology in Western countries due to lack fiber content diets, leading sigmoid colon make strong contractions end up but formation diverticula, with high risk inflammation infection. mainly interests people over 45 years old, without any gender preference. The refl...

  Lipomas of the gasterointestinal Tract are relatively uncommon in clinical practice. Most cases are asymptomatic with small tumor size and do not need any special treatment but the large ones are known to cause symptoms such as abdominal pain, obstruction, intussusceptions, and bleeding. The majority (90%) of these lesions are submucosal with predominantly right sided with a slight preponder...

Sigmoid volvulus is an unusual but an important cause of intestinal obstruction. It is associated with a high mortality especially when there is delayed diagnosis or when there is presence of gangrenous changes. The incidence of sigmoid volvulus is reducing in western world. We hereby report an interesting case of intestinal obstruction due to gangrenous sigmoid volvulus. Patient was fortunate ...

The colon involved with the sigmoid volvulus is much thicker than the normal colon. It is easy to handle and holds sutures well. Patients who have sigmoid-colon volvulus do not have much faecal loading. Most of the distension is gaseous. In the hands of experienced surgeons primary anastomosis can be done after sigmoid colectomy with safety and excellent results.

Our study is about feed-forward neural network’s learning method. Generally, the method of improving its learning is focused on learning rate and moment term. We focus on sigmoid functions. Sigmoid functions are used for converting input signal into output signal and adjusting connection weight of learning in feed-forward neural network. We change gradient of sigmoid functions and investigate o...

Prolapsed epiploica of the sigmoid colon through the vaginal cuff is a rare finding that has never been reported after total laparoscopic hysterectomy. We encountered a case of prolapsed epiploica of the sigmoid colon in a 40-year-old female, 4 months status after total laparoscopic hysterectomy. Diagnostic laparoscopy demonstrated prolapsed epiploica of the sigmoid colon through a dehisced vag...

This is a case of a 54-year-old gentleman who presented to an outside hospital emergency department with lower abdominal pain. Computed tomography imaging showed a small amount of intraperitoneal free air and cystic pneumatosis coli. He was admitted, managed conservatively with intravenous antibiotics, and then discharged home after his symptoms improved. Elective laparoscopic sigmoid colectomy...
