Improving the diagnostic accuracy of hiatal hernia in patients undergoing bariatric surgery.

Background: Surgical correction of hiatal hernia (HH) during bariatric surgery has been found to improve patient outcomes and decrease reoperation rate. Although barium esophagram is more sensitive than endoscopy for detection of HH, accurate preoperative diagnosis remains a challenge. The aim of this study is to determine whether diagnostic accuracy improves by utilizing right anterior oblique (RAO) esophagram technique instead of the commonly used upright technique when comparing to the gold standard of intraoperative detection.

Tests of correlation between immediate postoperative gastroduodenal transit times and weight loss after laparoscopic sleeve gastrectomy.

Background: Previous studies have shown accelerated gastric emptying after sleeve gastrectomy. This study aimed to determine whether a correlation exists between immediate postoperative gastroduodenal transit time and weight loss after laparoscopic sleeve gastrectomy (LSG). Specifically, correlation tests were conducted to determine whether more rapid transit after LSG correlated with increased weight loss.
