Hiatal hernia surgery serves as a suitable training procedure for upper gastrointestinal tract surgeons transitioning to the robotic approach. This study aims to evaluate the outcomes of implementing the robotic approach in hiatal hernia surgery at a tertiary hospital and to assess the associated learning curve. A retrospective review was conducted on 54 patients (58 surgeries) between June 2019 and March 2024, including both primary and revision robotic antireflux surgeries. The study focused on perioperative outcomes, symptom resolution, and the surgical learning curve, assessed using Cumulative Sum analysis. The results showed that global surgical time averaged 124 ± 57 (54-350) min, 127 ± 38 (116-139) for Primary Surgery and 164 ± 84 (115-212) min for Revisional Surgery. There were no conversions to laparoscopic or open approach. The global median of hospital stay was 2 days (2 for Primary Surgery and 3 for Revisional Surgery) and three patients required readmission (2 for Primary Surgery and 1 for Revisional Surgery). Postoperative complications occurred in 3 patients. Symptom resolution was achieved in 90% of Primary Surgery group and 85.7% of Revisional Surgery group. Learning curve described three phases: 1-training (case 1 to 14), 2-plateau (15 to 25) and 3-expertise phase (25 onwards). The robotic approach in hiatal hernia surgery is feasible with minimal morbidity, short hospital stays, and excellent functional results. With previous experience in laparoscopic approach and esophagogastric surgery the learning curve can be reduced to 14 procedures.</p>","PeriodicalId":47616,"journal":{"name":"Journal of Robotic Surgery","volume":"19 1","pages":"51"},"PeriodicalIF":2.2,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11742325/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143013998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A cohort of 100 patients who underwent ss-RARP, performed by a single surgeon at the First Affiliated Hospital of Guangzhou Medical University between March 2021 and June 2023, was retrospectively analyzed. To evaluate the learning curve, the CUSUM (Cumulative Sum Control Chart) technique was applied, revealing the progression and variability over time. A cubic polynomial model was utilised to fit the non-linear data trends accurately. Key perioperative outcomes, such as operative duration and estimated blood loss, were assessed and compared between distinct learning stages to identify improvements and transitions during the surgeon's proficiency development. A total of 100 patients were included, with a mean age of 71.44 ± 5.46 years. The median operative time was 119.53 min (94, 144), and the best-fit equation for the CUSUM learning curve of operative time was y = 387.0373 - 3.4334x - 0.2982x<sup>2</sup> + 0.003x<sup>3</sup> (R<sup>2</sup> = 0.898), reaching its peak at the 11th case. The median blood loss was 49.9 ml (20, 50), and the best-fit equation for the CUSUM learning curve of blood loss was y = 444.9362 + 23.6787x - 0.7719x<sup>2</sup> + 0.0049x<sup>3</sup> (R<sup>2</sup> = 0.957), reaching its peak at the 27th case.

One thousand sixteen patients were matched between Palmer and umbilical groups and 310 between Veress needle and open groups. Umbilical insertion was associated with more complications than Palmer (OR 2.14, p = 0.033). Patients requiring more than four needle attempts had higher complication rates (OR 15.43, p = 0.002). Severe adhesions significantly increased complications. After adjustment, the choice of entry method was not independently associated with complications.

The primary objective of the review is to explore the intersection of AI and robotic technologies in surgical practices, highlighting key innovations, their impact on precision medicine, and future trajectories. The novelty of the review lies in synthesizing findings across diverse surgical specialties, including urology, plastic surgery, ophthalmology, and pediatric surgery, to provide a comprehensive understanding of AI's transformative role. The systematic review evaluates the integration of AI and robotics in surgery, synthesizing studies published in 2024. It follows PRISMA guidelines for study selection, data extraction, and synthesis. The review assesses surgical specialties, AI technologies, and outcomes like accuracy, recovery, and complications, ensuring methodological rigor and transparency. The findings indicate substantial advancements in AI-driven surgical systems, improving decision-making, reducing surgical errors, and facilitating personalized treatment strategies. Notable breakthroughs include AI-enhanced imaging, real-time data analysis, and automated robotic instruments, which collectively improve procedural efficiency and patient safety. The discussion emphasizes the critical implications of these innovations, particularly in advancing minimally invasive techniques and expanding surgical capabilities in complex procedures. However, challenges such as cost, ethical considerations, and the need for rigorous training protocols are highlighted as barriers to widespread adoption. The review underscores the implications for policymakers, healthcare institutions, and technology developers to address these barriers and promote equitable access to AI-driven surgical solutions.
