HAMILTON S., James; ONETTO C., Camila; ORELLANA E., Omar  and  MARIN P., Pablo. Initial experience with robotic assisted revisional bariatric surgery. Rev Chil Cir [online]. 2018, vol.70, n.3, pp.241-244. ISSN 0718-4026.


Robotics in bariatric surgery is a novel development in medical institutions in Chile. Revisional bariatric procedures have increased during the last years. There are no publications in our country related to the initial experience and results in robotic revisional bariatric surgery. The aim of this study is to describe the initial experience and short term outcomes with robotic revisional bariatric surgery.

Study Design

We conducted a retrospective study of all consecutive robotic revisional bariatric surgeries performed by a single surgeon in Clínica Santa María in Santiago, Chile. We analyzed demographic characteristics and surgical outcomes, morbidity, mortality and length of hospital stay.


59 revisional bariatric surgeries were performed, 11 reshaping of sleeve gastrectomy, 34 Roux in Y gastric bypass, 1 pouch reshaping of Roux in Y gastric bypass, 3 extractions of laparoscopic adjustable gastric banding, 1 of them with simultaneous sleeve gastrectomy, 5 laparoscopic adjustable gastric banding to patients with previous Roux in Y gastric bypass, 3 total gastrectomy, 1 resection of gastro-gastric fistula and 1 gastro enteral anastomosis. Mean age was 47.8 years. Average preoperative body mass index was 33.86 kg/m2. Mean surgical time was 101.63 minutes. Postoperative complications were observed in 3 patients (5.08%). In 2 (3.39%) of this patient, reoperation was required. There were no deaths in this group. Average length of hospital stay was 3.6 days.


Robotic revisional bariatric surgery is a novel technique that appears to be safe and effective.
