Background:
Sleeve gastrectomy (SG) has become a frequent bariatric procedure. Single-port sleeve gastrectomy (SPSG) could reduce parietal aggression however its development has been restrained due to fear of a complex procedure leading to increased morbidity and suboptimal sleeve construction. The aim of this study was to compare the short-term outcomes of SPSG versus conventional laparoscopic sleeve gastrectomy (CLSG) with regards to morbidity, weight loss, and co-morbidity resolution.
Methods:
Between January 2015 and December 2016, data from all consecutive patients that underwent SPSG and CLSG in two institutions performing exclusively one or the other approach were retrospectively analyzed. Propensity score adjustment was performed on the factors known to influence the choice of approach.
Results:
During the study period, 1122 patients underwent SG in both institutions (610 SPSG and 512 CLSG). From each group, 314 patients were successfully matched. A 15-min increase in operative time was observed during SPSG (P < 0.001). Postoperative morbidity was similar with a minor increase after SPSG (8.6 vs. 6.7%, P = 0.453). No differences in incisional hernia rates were observed (1.6 (SPSG) vs. 0.3% (CLSG), P = 0.216). Percentage of total weight loss was 31.1% and 28.2% in the CLSG and SPSG 12 months after surgery, respectively (P = 0.321). Co-morbidities resolution 12 months following the procedure was similar.
Conclusions:
SPSG can be performed safely with similar intraoperative and postoperative morbidity compared to CLSG. Weight loss and co-morbidities resolution at 1 year are equivalent. A 15-min longer operative time was the only negative side of SPSG.
