Robotic Single Anastomosis Duodeno-Ileal Switch (SADI-S) is a minimally invasive weight loss surgery that has gained popularity in recent years. It is a modification of the traditional duodenal switch procedure, and it involves creating a single anastomosis between the stomach and the ileum, bypassing a significant portion of the small intestine to reduce the amount of calories absorbed. The use of robotics in SADI-S surgery has advantages such as improved visualization, more precise dissection, and reduced tissue trauma compared to traditional open surgery. The indications for robotic SADI-S are similar to those for traditional weight loss surgeries, including a body mass index (BMI) of 40 or greater or a BMI of 35 or greater with obesity-related comorbidities. Patients with a history of previous abdominal surgeries or significant gastroesophageal reflux disease may not be suitable candidates for the procedure. The history of SADI-S surgery can be traced back to the early 2000s when it was first described as a modification of the duodenal switch procedure. It was initially performed using traditional open surgery techniques but has since evolved to minimally invasive laparoscopic and robotic-assisted surgery. Robotic SADI-S was first reported in the literature in 2014, and since then, numerous studies have reported its safety and efficacy in weight loss and comorbidity improvement. In conclusion, robotic SADI-S is a minimally invasive weight loss surgery that has gained popularity in recent years. It is indicated for patients with a BMI of 40 or greater or a BMI of 35 or greater with obesity-related comorbidities. The use of robotics in SADI-S surgery allows for improved visualization, more precise dissection, and reduced tissue trauma. Robotic SADI-S has shown to be safe and effective in weight loss and comorbidity improvement, and it continues to evolve as a surgical option for the treatment of obesity.

The super specialty of complex abdominal wall reconstruction continues to evolve based on advanced techniques built upon the shoulders of those who created the initial stages of component separation at the end of the twentieth century. With the advent of technological advances such as robotic surgery, a refined approach has been developed which allows for bilateral myocutaneous flaps creation from an extraperitoneal plane, specifically preperitoneal, known as the extended preperitoneal (eTEP) approach. The robotic platform offers numerous ergonomic advantages to the surgeon which allow for performance of a complex reconstruction of the abdominal wall with attention to detail in all aspects of hernia repair including dissection of the hernia sac and reduction of the hernia contents, a primary repair of the defect under minimal or no tension, plication of associated rectus diastasis, and mesh implantation as a preperitoneal/retrofascial/retromuscular sublay. This SOC will illustrate the robotic extended totally extraperitoneal (eTEP) approach for ventral hernia repair with plication of associated rectus diastasis as a useful adjunct to the minimally invasive surgeon’s toolset and the most recent novel technique for complex abdominal wall reconstruction.
