Tests of correlation between immediate postoperative gastroduodenal transit times and weight loss after laparoscopic sleeve gastrectomy
Surgical Endoscopy, 06/12/2012
Parikh M et al. – No correlation was found between gastroduodenal transit time and weight loss after laparoscopic sleeve gastrectomy (LSG).Methods
- Data were collected from an institutional review board–approved electronic registry.
- All LSGs were performed over a 40–Fr bougie, starting 5 to 7 cm proximal to the pylorus.
- Gastroduodenal transit time (antrum to duodenum) was calculated from a postoperative day 1 esophagram.
- Pearson’s correlation coefficient was used for statistical analysis.
- The analysis included 62 consecutive LSG patients.
- The mean gastroduodenal transit time was 12.3 ± 19.8 s. Almost all the patients (99 %) had a transit time less than 60 s.
- The mean percentage of excess weight loss (%EWL) was 23.8 ± 9.8 % at 3 months, 37.9 ± 11.8 % at 6 months, and 52.2 ± 10.8 % at 12 months.
- No correlation was found between gastroduodenal transit time and %EWL at 3, 6, or 12 months.
