To investigate the safety and efficacy of Da Vinci robotic-assisted hiatal hernia repair surgery, and to summarize the experience based on single- center data.

The clinical data of 152 patients who underwent robotic- assisted hiatal hernia repair surgery by the same team in the General Surgery Department of the Affiliated Hospital of Xuzhou Medical University from December 2019 to November 2023 were retrospectively analyzed. Improvements in post- operative symptoms were assessed using the Gastroesophageal Reflux Disease Questionnaire (GerdQ). The learning curve was analyzed through the cumulative sum analysis method of operation time (CUSUMOT)

All 152 patients successfully underwent the surgical procedure, with an operative time of (98.9±38.1) minutes, and intraoperative blood loss of (46.7±19.4) mL. There were no cases requiring blood transfusion, conversion to open or laparoscopic surgery, or serious intraoperative complications. The post-operative hospital stay averaged (2.0±1.2) days, with no occurrences of severe complications classified as Clavien-Dindo grade ≥ III. All patients completed follow-up: three months post-operation, 5 cases (3.3%) experienced dysphagia, 4 cases (2.63%) reported diarrhea, and the postoperative GerdQ score significantly decreased compared to pre-operation［(6.4±0.9) vs. (11.1±3.4), P<0.05］. There were no symptomatic or anatomical recurrences three months post- operation. The peak of the learning curve was observed between the 4th and 5th patients, after which the operative time substantially decreased and remained stable.

The learning curve for Da Vinci robotic- assisted hiatal hernia repair surgery is short. The procedure is safe and effective.
