This study introduces a novel transumbilical stapling technique for single-incision laparoscopic surgery (SILS) in one anastomosis gastric bypass (OAGB). This advancement addresses challenges in creating the gastric tube, enhancing cosmetic outcomes for bariatric surgery patients.

Area of Science:

  • Minimally Invasive Bariatric Surgery
  • Surgical Innovation
  • Gastrointestinal Surgery

Background:

  • Single-incision laparoscopic surgery (SILS) offers superior cosmetic results compared to conventional laparoscopy.
  • SILS has been applied to various bariatric procedures, including sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB).
  • Previous modifications like the transumbilical two-site (TUTS) technique were developed for RYGB but not OAGB due to technical complexities.

Purpose of the Study:

  • To present a novel transumbilical stapling technique for single-incision laparoscopic surgery (SILS) in one anastomosis gastric bypass (OAGB).
  • To overcome the challenges associated with creating a slender gastric tube for OAGB using a single incision.
  • To adapt and refine SILS for complex bariatric procedures like OAGB.

Main Methods:

  • Development of a novel transumbilical stapling technique specifically for OAGB.
  • Adaptation of the transumbilical two-site (TUTS) approach principles for OAGB.
  • Focus on creating a 25 cm slender gastric tube within the constraints of SILS.

Main Results:

  • Successful development of a tailored transumbilical stapling technique for OAGB.
  • Demonstration of a viable SILS approach for OAGB, overcoming previous limitations.
  • Potential for improved cosmetic outcomes in OAGB patients through SILS.

Conclusions:

  • The novel transumbilical stapling technique represents a significant advancement in SILS for OAGB.
  • This technique facilitates the application of SILS to complex bariatric procedures, expanding minimally invasive options.
  • Further studies are warranted to evaluate the long-term efficacy and outcomes of this SILS approach for OAGB.
