This study shows the SurgASSIST system is feasible for intracorporeal esophagogastrostomy during laparoscopic proximal gastrectomy. While effective, improvements are needed for the device
Area of Science:
- Minimally Invasive Surgery
- Surgical Oncology
- Gastrointestinal Surgery
Background:
- Intracorporeal esophagogastrostomy following laparoscopic proximal gastrectomy presents significant technical challenges.
- Gastrointestinal stromal tumors near the esophagogastric junction necessitate advanced surgical reconstruction techniques.
Observation:
- The SurgASSIST system, a computer-mediated flexible circular stapler, was utilized for esophagogastrostomy in two patients with tumors near the esophagogastric junction.
- The double-stapling technique enabled successful intracorporeal anastomosis.
Findings:
- The SurgASSIST system demonstrated feasibility for esophageal anastomosis in laparoscopic proximal gastrectomy.
- No instances of anastomotic leakage were observed in the cases.
- One patient developed anastomotic stricture requiring balloon dilatation.
Implications:
- Further refinement of the digital loading unit (DLU) is crucial to overcome limitations in transoral introduction and reduce risks of esophageal injury.
- Improvements to the DLU could expand the application of this system in various laparoscopic surgical procedures.
