Diaphragmatic crural eventration
AIM We evaluated patients with gastric volvulus secondary to diaphragmatic pathology. MATERIALS AND METHODS Eight patients (5 males and 3 females) presented to the author in a tertiary care center during 1997-2006 were analyzed in terms of age, sex, symptomatology, diagnosis and predisposing factors. OBSERVATIONS Six had an acute presentation and rest had chronic symptomatology. The two pat...
متن کاملEffect of straining on diaphragmatic crura with identification of the straining-crural reflex. The "reflex theory" in gastroesophageal competence
BACKGROUND The role of the crural diaphragm during increased intra-abdominal pressure is not exactly known. We investigated the hypothesis that the crural diaphragm undergoes reflex phasic contraction on elevation of the intra-abdominal pressure with a resulting increase of the lower esophageal pressure and prevention of gastro-esophageal reflux. METHODS The esophageal pressure and crural dia...
متن کاملThe effects of antireflux surgery on asthmatics with gastroesophageal reflux.
BACKGROUND Antireflux therapy, including surgery, has been advocated for asthma patients with gastroesophageal reflux (GER). A recent review of medical antireflux therapy reported improvements in asthma symptoms and medication requirements but no improvement in pulmonary function. The purpose of this article is to review the available literature on the effects of antireflux surgery in asthma. ...
متن کاملEffect of lower esophageal sphincter tone and crural diaphragm contraction on distensibility of the gastroesophageal junction in humans.
Previous studies of distensibility of the gastroesophageal junction (GEJ) in humans have not tried to distinguish between the effects of muscle action and passive elastic tissue properties of the GEJ. We studied 15 healthy subjects (ages 23-67 yr, 11 men/4 women) by using a catheter with a highly complaint bag positioned manometrically at the GEJ. The bag was distended with air at a rate of 20 ...
متن کاملTherapy of gastroesophageal reflux: evidence-based approach to antireflux surgery.
BACKGROUND Due to the chronic, relapsing nature of gastroesophageal reflux disease, lifelong therapeutic options have to be considered and recommended in many patients. Accordingly, surgical repair has to be evaluated based on modern, evidence-based methodologies. METHODS A careful review has been carried out of the relevant surgical literature also including trials incorporating direct compa...
