The transumbilical route began being clinically feasible with or without unique access devices.


The setting for this study was a private practice at Clínica Las Condes, Santiago, Chile.


The objective was to describe our experience performing a laparoscopic sleeve gastrectomy (LSG) via transumbilical route using a single-port access device in addition to standard laparoscopic instruments.


A prospective nonrandomized protocol was applied to patients fulfilling the following inclusion criteria: to have been medically indicated for an LSG, to have a body mass index (BMI) of less than or equal to 40 kg/m2, and the distance between the xiphoid appendix and umbilicus should be less than 22 cm. All patients were female with a median (p50) age of 34.5 (ranging from 21 to 57) years, a median weight of 92 (ranging from 82.5 to 113) kg, and a median BMI of 35.1 (ranging from 30.5 to 40) kg/m2. The device insertion technique, the gastrectomy, and postoperative management are described.


LSG via transumbilical route was successfully carried out in 19 of the 20 patients in whom the procedure was performed; one patient had to be converted to a conventional laparoscopic procedure. Mean operating time was 127 (ranging from 90 to 170) min. On the second postoperative day, all patients were assessed through an upper gastrointestinal barium-contrasted radiological series. There was neither morbidity nor mortality in this group. Excess weight loss at 25 months after surgery was 114 %.


Single-port LSG can be successfully performed in selected obese patients with a BMI of less than 40 kg/m2 using traditional laparoscopic instruments. The technique allows performing a safe and effective vertical gastrectomy.
