Gastric volvulus is a rare and life-threatening abdominal pain

Gastric volvulus is a rare and life-threatening abdominal pain condition resulting from the stomach twisting on its own longitudinal (organo-axial) or transverse (mesentero-axial) axis. Gastric volvulus can be primary or secondary. Secondary is most commonly related to para-esophageal hernia. Gastric volvulus can have an acute or chronic presentation, the acute form presents abdominal pain with a risk of gastric ischemia with subsequent perforation. Diagnosis is made by imaging studies such as barium contrast studies in the upper digestive tract or abdominal and chest computed tomography (CT). CT of the abdomen and thorax is very useful in the diagnosis as it can demonstrate the abnormal position and gastric torsion The goal in the definitive treatment of gastric volvulus is resolution of gastric obstruction and prevention of recurrence. Performing volvulus reduction, repair of the concomitant cause (para-esophageal hernia), fundoplication and/or gastropexy to the anterior abdominal wall. Gastropexy is considered safe and effective in elderly patients with high surgical risk.

Gastric Obstruction by Tricobezoar in Cat Associated with Lynxacarus radovskyi: a Case Report

The presence of trichobezoar in cats is characterized by the accumulation of hair in the gastric cavity, which may be associated with the presence of dermatitis caused by the presence of the mite Lynxacarus radovskyi. In the present report, a clinical case of a feline patient with diagnostic and surgical diagnosis of the presence of a trichobezoar with the presence of Lynxacarus radovskyi in a skin scrape examination was described.

The Pathogenesis of Proventricular Dilatation Disease Caused by Parrot Bornaviruses: A Possible Role For Neuropeptide Y (Npy)

Background Psittacine Bornaviruses cause a unique disease syndrome in parrots and related birds. Known as proventricular dilatation disease (PDD), it is characterized by massive dilatation of their proventriculus as a result of excessive food accumulation within that organ. This leads to gastric obstruction and eventually, to death by starvation. Results In a preliminary study on the transcriptome of psittacine bornavirus-infected human astroglia it was noted that the gene encoding neuropeptide Y was significantly upregulated. In a subsequent study of cockatiels experimentally infected with the same strain of psittacine bornavirus, their brains were examined by RNA-seq to determine which genes were being actively transcribed. It was confirmed that among the genes whose expression was significantly increased relative to control, uninfected birds was that for neuropeptide Y. Conclusions Neuropeptide Y is known to cause overeating in birds. We hypothesize therefore that the clinical manifestations of proventricular dilatation disease are a result of the excessive production of neuropeptide Y by bornavirus-infected brain cells acting in association with damage to the neurons of the proventricular myenteric plexus.

Acute massive gastric dilatation: a rare, forgotten complication of fundoplication

An 8-year-old boy with a history of multiple neonatal laparotomies, including congenital diaphragmatic hernia repair and an open fundoplication, presented acutely with severe abdominal pain, distension, vomiting and shock. A large abnormal opacity in the left upper quadrant was visible on a plain abdominal radiograph. The patient was taken to the theatre for emergency laparotomy and was found to have a massively distended stomach, the fundus and body of which were necrotic. A subtotal gastrectomy was performed, sparing the viable tissue. The patient went on to make a full recovery. Acute massive gastric dilatation (AMGD) is a rare condition characterised by severe gastric distension. Gastric ischaemia results when intragastric pressure exceeds venous pressure, obstructing venous outflow. It is important to recognise AMGD as a severe complication of fundoplication due to closed-loop gastric obstruction. It should prompt consideration of an early laparotomy in cases where the diagnosis is suspected.
