Gastric volvulus or volvulus of stomach is a twisting of all or part of the stomach by more than 180 degrees with obstruction of the flow of material through the stomach, variable loss of blood supply and possible tissue death. The twisting can occur around the long axis of the stomach, called organoaxial, or around the axis perpendicular to ...
Gastric volvulus causes nausea, vomiting, and pain in the upper abdomen. The Borchardt triad is a group of symptoms that help doctors to identify gastric volvulus. The symptoms are intractable retching, pain in the upper abdomen and inability to pass nasogastric tube into the stomach.
Note the tense wall indicative of gas under pressure and volvulus. Bowel infarction or gangrenous bowel represents an irreversible injury to the intestine resulting from insufficient blood flow. It is considered a medical emergency because it can quickly result in life-threatening infection and death. [ 1 ]
In cases of volvulus, plain radiography may demonstrate signs of duodenal obstruction with dilatation of the proximal duodenum and stomach but it is often non-specific. Ultrasonography may be useful in some cases of volvulus, depicting a "whirlpool sign" where the superior mesenteric artery and superior mesenteric vein have twisted. [7]
Based on evidence from people with other health problems crystalloid and colloids are believed to be equivalent for peptic ulcer bleeding. [15] In people with a confirmed peptic ulcer, proton pump inhibitors do not reduce death rates, later bleeding events, or need for surgery. [18] They may decrease signs of bleeding at endoscopy however. [18]
Depending on the level of obstruction, bowel obstruction can present with abdominal pain, abdominal distension, and constipation.Bowel obstruction may be complicated by dehydration and electrolyte abnormalities due to vomiting; respiratory compromise from pressure on the diaphragm by a distended abdomen, or aspiration of vomitus; bowel ischemia or perforation from prolonged distension or ...
The football sign is most frequently seen in infants with spontaneous or iatrogenic gastric perforation causing pneumoperitoneum. It is also seen in bowel obstruction with secondary perforation, as in Hirschprung disease, midgut volvulus, meconium ileus and intestinal atresia. Iatrogenic causes like endoscopic perforation may also give football ...
Gastric aspiration and or lavage, where a tube is inserted into the stomach via the nose in an attempt to determine if there is blood in the stomach, if negative does not rule out an upper GI bleed [20] but if positive is useful for ruling one in. [14] Clots in the stool indicate a lower GI source while melana stools an upper one. [14]
