Purpose: Laparoscopic sleeve gastrectomy (SG) is now frequently performed as a definitive bariatric procedure. The aim of the study was to evaluate the detailed morphology of remnant stomachs after SG with respect to volume and sleeve migration.
Materials and Methods: We performed a retrospective review of prospectively collected data on patients that completed a 12-month postop examination, which included CT volumetry of sleeve, and a questionnaire that addressed postop food tolerance. CT volumetry study included total sleeve volume (TSV), tube volume (TV), antral volume (AV), tube/antral volume ratio (TAVR), and the presence of intrathoracic sleeve migration (ITSM).
Results: Fifty-five patients were included in this retrospective study. Mean %TWL (% total weight loss) at 12 months postop was 32.8% (14.3-55.5), and mean TSV, TV, AV, and TAVR were 166.6¡¾63.3 ml, 68.9¡¾35.4 ml, 97.7¡¾42.9 ml, and 0.8¡¾0.6 respectively. TSV was not correlated significantly with %TWL at 12 months postop (r=?0.069, P=0.619). Fourteen patients (14/55, 25.5%) showed ITSM by CT. Patients with ITSM had a significantly lower mean GER score (5.1¡¾2.0 vs. 7.3¡¾2.0, P=0.001), a lower total food tolerance score (21.6¡¾3.8 vs. 24.4¡¾4.6, P=0.048), and a higher proportion showed suboptimal weight loss (35.7% vs. 9.8%, P=0.023).
Conclusion: Mean TSV was not found to be significantly correlated with %TWL at 12 months postop. Patients with suboptimal weight loss had higher mean TAVR, and the presence of ITSM indicated more frequent GER symptoms, lower food tolerance, and a higher probability of suboptimal weight loss.
