Background: Single-incision laparoscopic surgery has attracted a great deal of interest in the surgical community in recent years, including bariatric surgery. Literature is scarce about operative and clinical outcomes of single port sleeve gastrectomy (SPSG) compared to conventional laparoscopy. SPSG has been proposed as an alternative to the multiport laparoscopic procedure; however, it has yet to meet wide acceptance and application.

Methods: This was a prospective non-randomized clinical study, to evaluate the feasibility and short-term outcomes of SPSG in comparison to the conventional multiport sleeve gastrectomy (MPSG).

Results: Weight loss, resolution of comorbidities, length of hospital stay, complications were almost comparable in both groups. Operating times were longer in SPSG group. Two patients only required re-laparoscopy, one in either group. There were no leakage or mortalities. Patients in the SPSG group had better wound satisfaction and less post-operative pain.

Conclusions: SPSG is a safe, effective, and feasible surgical procedure for morbid obesity in selected individuals and comparable to the conventional laparoscopic technique in terms of outcomes. It has equally effective weight loss and resolution of comorbidities. It also has the added benefits of little/ no visible scarring and reduced postoperative pain.
