Learning Curve for Robotic Sleeve Gastrectomy and Roux-en-Y Gastric Bypass: Achieving Equivalence to Laparoscopy

Katherine D Gray, MD, Adham Elmously, MD, Michael P Choi, MD, Patrick T Dolan, MD, Gregory Dakin, MD, Alfons Pomp, MD, Cheguevara Afaneh, MD. New York-Presbyterian-Cornell

Introduction: The robotic platform is increasingly utilized for bariatric procedures, but the learning curve has not been well described.  We aimed to evaluate perioperative morbidity and operative times for robotic sleeve gastrectomy (RSG) and robotic Roux-en-Y gastric bypass (RRYGB) based on number of procedures performed.

Methods and Procedures: Retrospective review was conducted of all adult patients undergoing RSG or RRYGB by a minimally invasive fellowship-trained surgeon in his first two years of attending practice at a Bariatric Center of Excellence (2015-2017). Linear regression fit lines over number of procedures performed were constructed to describe learning curves for RSG and RRYGB. Operative time was compared within procedure to our institutional averages for patients undergoing laparoscopic sleeve gastrectomy (LGS) or laparoscopic Roux-en-Y gastric bypass (LRYGB). Residents and fellows participated in an analogous fashion in both arms of the study, and patients undergoing re-operative bariatric surgery were excluded.

Results: A total of 109 patients undergoing RSG (n = 84) or RRYGB (n = 25) were included. For the overall robotic cohort, median age was 38 (range 19-69), 36% were American Society of Anesthesiologists (ASA) score 2, 60% were ASA score 3, and mean body mass index (BMI) was 46 +/- 7 with no differences between procedures.

There were no conversions to open. There was one patient with portal vein thrombosis after RSG which occurred in the 84th RSG and one patient who underwent re-operation in the immediate post-operative period for hemorrhage at the gastro-jejunal anastomosis in the RRYGB group; this occurred in the 8th RRYGB. There were no leaks, strictures, or mortalities in either group. Mean length of stay was 2 days +/- 1 for RSG with no difference based on number of procedures performed. In the RRYGB group, LOS decreased after the first five procedures from 3 days +/- 1 to 2 days +/-1 (p = 0.04). 

For both procedures, operative time decreased by number of procedures performed (Figure). Equivalence to LSG in operative time (118 minutes +/- 40) was reached after eight robotic procedures; equivalence to LRYGB in operative time (169 minutes +/- 47) was reached after twenty-two robotic procedures.

Conclusions: We show that equivalence in operative time to LSG and LRYGB was rapidly achieved using the robotic platform by a fellowship-trained bariatric surgeon in an institution’s first years of robotic bariatric practice. Perioperative morbidity was minimal throughout the study period.

Respuesta de SAGES al Estudio NordICC sobre el beneficio de las colonoscopias de detección

SAGES desea aclarar los resultados del estudio NordICC y colocarlos en contexto de los esfuerzos de varias agencias nacionales para reducir el riesgo de cáncer colorrectal – la segunda causa de muerte por cáncer más frecuente en los Estados Unidos-, mediante la promoción de la detección y tratamiento oportuno de las lesiones.

SAGES Response to NordICC Study Regarding Benefit of Screening Colonoscopies

The NordICC Study recently published in The New England Journal of Medicine and widely reported on by media outlets has raised questions regarding the benefit of screening colonoscopy in lowering the risk of colorectal cancer and cancer-related deaths among otherwise healthy and symptom-free men and women aged 55 to 64. Provocative headlines and commentaries have […]
