Large bowel volvulus accounts for 10-30% of all large bowel obstruction and occurs most commonly in the sigmoid colon(Asbun 1992, Bagarani 1993, Bhatnagar 2004, Oren 2007, Pahlman 1989 ). It is more common in the region of Africa, South America, Middle East and Southern Asia. The most common site of volvulus include sigmoid colon(80%), caecum(15%), transverse colon(3%), splenic flexure(2%) and ...

Ileo-sigmoid knotting (ISK) is one of the uncommon causes of bowel obstruction except in sigmoid volvulus belt countries where it is fairly common. Bowel obstruction during pregnancy is also uncommon; when it occurs it is mostly due to adhesions. Obstruction during labor is a very rare phenomenon. In this article we present a case of ISK diagnosed intra operatively in a grand-multipara mother t...

Background: Sigmoid volvulus is a common cause of intestinal obstruction in developing countries where it affects relatively young people. Little is known about this condition in our country and there is yet no literature from an environment like ours (northern Uganda) where civil war has devastated the economy with most of the populace displaced into internally displaced peoples’ camp. The mai...

thickened wall of the distal sigmoid colon, an ileosigmoid fistula (Fig. A), and lymphadenopathy in the abdomen and pelvis with a maximum measurement of 4.0×2.6 cm. Barium enema revealed the two paths around the rectosigmoid junction. One was the usual sigmoid colon with remarkable mucosal abnormalities. The other was the ileosigmoid fistula Question: A 43-year-old man presented with diarrhea a...

Ileosigmoid knot, also known as compound volvulus, is an unusual and a rare cause of intestinal obstruction. We are reporting a case of ileosigmoid knot in a 30-year-old male, who presented with lower abdominal pain. On examination, there was tenderness in the suprapubic area and later, the patient developed features of peritonitis. Exploratory laparotomy revealed a large volume of haemorrhagic...

In the 1980’s, knotting in DNA became a fundamental research dimension in the study of the mechanisms by which enzymes act on it. Later, the first compelling identification of knotting in proteins, in 2000, launched the study of knotting in protein structures and linear macromolecules more generally following on theoretical efforts of the 1960’s. While the linking occurring in structures such a...
