Modified One Anastomosis Gastric Bypass Following Sleeve Gastrectomy for Severe Reflux and Delayed Gastric Emptying: A Prospective Trial with Clinical and Physiological Outcome Measures.

Background: Gastro-esophageal reflux (GORD) following sleeve gastrectomy (SG) is a central challenge, and precise indications for revisional surgery or the physiology have not been precisely defined. We aimed to determine whether OAGB performed for reflux post-SG (1) accelerates gastric emptying half-time, (2) reduces the frequency and severity of reflux events, and (3) improves reflux symptoms.

Methods: We undertook a prospective trial (ACTRN12616001089426).

Underutilisation of gastric emptying studies and underrecognition of gastroparesis in people with diabetes treated in a hospital setting.

Delayed gastric emptying occurs in up to 30% of patients with long-standing diabetes and causes significant morbidity. We performed a retrospective cohort study of 341 patients who had participated in a gastric emptying study from 2018 to 2021 in a large teaching hospital. Given the expected prevalence of gastroparesis in people with diabetes, there were fewer studies than anticipated, which could lead to gastroparesis underrecognition.

Changes in Oesophageal Transit, Macro-Reflux Events, and Gastric Emptying Correlate with Improvements in Gastro-Intestinal Symptoms and Food Tolerance Early Post Sleeve Gastrectomy.

Purpose: There are significant alterations in gastro-intestinal function, food tolerance, and symptoms following sleeve gastrectomy (SG). These substantially change over the first year, but it is unclear what the underlying physiological basis for these changes is. We examined changes in oesophageal transit and gastric emptying and how these correlate with changes in gastro-intestinal symptoms and food tolerance.
