Gastroesophageal Reflux and Bleeding Esophageal Varices

1979

The incidence of gastroesophageal reflux was evaluated with the use of a pH probe in 12 patients with cirrhosis and recent variceal hemorrhage and in 15 healthy control subjects. Short episodes of reflux occurred in 42% of the patients and in 47% of the controls. During an observation period of 1 hr, the cumulative duration of reflux was similar in patients (2.5 ± 1.3 min) and controls (3.1 ± 1.4 min). Mean lower esophageal sphincter pressures were normal in both groups but did not show a significant correlation with the duration of reflux. These data support previous observations that gastroesophageal reflux does not appear to be a contributing factor in the development of variceal hemorrh…

Do we understand the pathophysiology of GERD after sleeve gastrectomy?

2020

Gastroesophageal reflux disease (GERD), a prevalent problem among obese individuals, is strongly associated with obesity and weight loss. Hence, bariatric surgery effectively improves GERD for many patients. Depending on the type of bariatric procedure, however, surgery can also worsen or even cause a new onset of GERD. As a consequence, GERD remains a relevant problem for many bariatric patients, and especially those who have undergone sleeve gastrectomy (SG). Affected patients report not only a decrease in physical functioning but also suffer from mental and emotional problems, resulting in poorer social functioning. The pathomechanism of GERD after SG is most likely multifactorial and tr…

Manometric assessment of oesophageal involvement in progressive systemic sclerosis, morphoea and Raynaud's disease.

1982

SUMMARY Oesophageal function was studied by radiography and manometry in fifty-one patients with progressive systemic sclerosis (PSS), fourteen patients with morphoea, twelve patients with Raynaud's disease and twenty-one normal subjects. Upper oesophageal sphincter pressure was not affected. Peristaltic contractions of the upper third of the oesophagus were significantly decreased in PSS and morphoea, but the lower two-thirds were affected only in PSS. Lower oesophageal sphincter pressure was significantly decreased in PSS but was normal in morphoea and Raynaud's disease. There was a significant correlation between oesophageal dysfunction and the duration of PSS. Manometry was better than …
