The joints between segmental rings can withstand a certain amount of bending moment as well as axial and shear forces. Generally, in the structural analysis of tunnel segmental lining, the joints can be modeled as elastic hinges or rotational springs, and their rigidity should be demonstrated in terms of the rigidity of the joints or their rotational stiffness. Therefore, the bending moment act...

KEY CLINICAL MESSAGE Midgut volvulus can rarely present with acute chylous peritonitis. Common etiologies for chylous ascites need to be excluded before this diagnosis is made. Correction of the volvulus and peritoneal lavage suffice as treatment.

Abstract Sigmoid volvulus is a frequent cause of intestinal obstruction. Its management has evolved with the use laparoscopic surgery, achieving an elective sigmoid resection anastomosis after flexible endoscopic detorsion. A female patient was admitted to emergency room abdominal pain, distention, and constipation. The computed tomography showed whirled mesentery in addition dilated loops, cof...

Numerous patients use to refer to emergency rooms everyday due to abdominal pain all over the world. One of the rare conditions, among the several etiologies in these patients, is gastric volvulus. This pathology, which occurs via rotation of the stomach around its own axis more than 1800, may cause acute abdomen as well as may be asympthomatic [1]. Diaphragmatic hernia, which is suggested as a...

Reports of a volvulus (twisting) of the sigmoid colon can be found in a papyrus from ancient Egypt. However, sigmoid volvulus represents a spectrum of disease across the globe from young men in central Africa to the elderly institutionalised patients in Western Europe and the USA. As the population ages the prevalence of sigmoid volvulus is likely to rise. As an acute presentation, it represent...

Gastric dilatation and volvulus syndrome is associated with changes in haemostatic profiles. The aims of this study were to compare selected haemostatic and fibrinolytic parameters between healthy dogs and dogs with gastric dilatation and volvulus syndrome, estimate the incidence of disseminated intravascular coagulation (DIC), and determine the most sensitive test for detection of DIC in these...

Onchocerca volvulus infection has been associated with impaired cellular responses to parasite antigens, an impairment that may also extend to nonparasite antigens. To investigate the mechanism of this impaired immune response, the effect of concurrent O. volvulus infection on the immune response to tetanus toxoid (TT) following tetanus vaccination was studied. The proliferative, cytokine, and ...

I read with great interest the recent article by Papiamonis et al.1 One gastrointestinal complication that is seen with an increased frequency in patients with Cornelia de Lange syndrome and that is often under-reported is intestinal volvulus. Volvulus in Cornelia de Lange syndrome is most common in the cecal portion of the intestine. Non-fixation of the caecum is the most common attributable c...

Background: Sigmoid volvulus is a rare complication in pregnancy. The clinical presentation is similar to that of non-pregnant volvulus, although the symptoms can be masked by the enlarged uterus and physiological changes during pregnancy and it can be challenged and delayed in diagnosis and treatment. Delay in diagnosis can also lead to ischemia, necrosis and perforation of the intestine, whic...

Introduction: in Hippocrates’ Affections, treatment of volvulus involved injecting air into colon through anus and inserting suppository 10 digits (22 cm)-long; variations on these treatments still in use today Colonic volvulus: incidence — third most common cause of colonic obstruction worldwide; accounts for 2% to 4% of cases of colonic obstruction in United States but ≤50% of cases in “volvu...
