Robotic Complex Fundoplication in Patients at High-Risk to Fail

Diagnosis to dissection: AI's role in early detection and surgical intervention for gastric cancer

Gastric cancer remains a formidable health challenge worldwide; early detection and effective surgical intervention are critical for improving patient outcomes. This comprehensive review explores the evolving landscape of gastric cancer management, emphasizing the significant contributions of artificial intelligence (AI) in revolutionizing both diagnostic and therapeutic approaches. Despite advancements in the medical field, the subtle nature of early gastric cancer symptoms often leads to late-stage diagnoses, where survival rates are notably decreased. Historically, the treatment of gastric cancer has transitioned from palliative care to surgical resection, evolving further with the introduction of minimally invasive surgical (MIS) techniques. In the current era, AI has emerged as a transformative force, enhancing the precision of early gastric cancer detection through sophisticated image analysis, and supporting surgical decision-making with predictive modeling and real-time preop-, intraop-, and postoperative guidance. However, the deployment of AI in healthcare raises significant ethical, legal, and practical challenges, including the necessity for ongoing professional education and the development of standardized protocols to ensure patient safety and the effective use of AI technologies. Future directions point toward a synergistic integration of AI with clinical best practices, promising a new era of personalized, efficient, and safer gastric cancer management.

A decade of experience with minimally invasive anti-reflux operations: robot vs. LESS

BACKGROUND

The increasing use of robotic systems for anti-reflux operations prompted this study to evaluate and compare the efficacy of robotic and Laparo-Endoscopic Single-Site (LESS) approaches.

METHODS

From 2012, 228 robotic fundoplication and 518 LESS fundoplication patients were prospectively followed, analyzing perioperative metrics. Data are presented as median (mean ± SD); significance at p ≤ 0.05.

RESULTS

Patients undergoing a robotic vs. LESS fundoplication were 67 (64 ± 13.7) vs. 61 (59 ± 15.1) years-old with BMIs of 25 (25 ± 3.2) vs. 26 (25 ± 3.9) kg/m2 (p = 0.001 and 1.00, respectively). 72% of patients who underwent the robotic approach had a previous abdominal operation(s) vs 44% who underwent the LESS approach (p = 0.0001). 38% vs. 8% had a re-operative fundoplication (p = 0.0001), 59% vs. 45% had a type IV hiatal hernia (p = 0.0004). Operative duration was 160 (176 ± 76.7) vs. 130 (135 ± 50.5) min (p = 0.0001). There were 0 (robotic) vs. 5 (LESS) conversions to a different approach (p = 0.33). 5 Patients vs. 3 patients experienced postoperative complications (p = 0.06), and length of stay (LOS) was 1 (2 ± 2.6) vs. 1 (1 ± 3.2) days (p = 0.0001). Patient symptomatic dysphagia preoperatively for the robotic vs. LESS approach was scored as 2 (2.4 ± 1.9) vs. 1 (1.9 ± 1.6). Postoperatively, symptomatic dysphagia was scored as 1 (1.5 ± 1.6) vs. 1 (1.7 ± 1.7). The change in these scores was - 1 (- 1 ± 2.2) vs. 0 (- 0.5 ± 2.2) (p = 0.004).

CONCLUSION

Despite longer operative times and LOS in older patients, the robotic approach is efficient in undertaking very difficult operations, including patients with type IV or recurrent hiatal hernias. Furthermore, preoperative anti-reflux operations were more likely to be undertaken with the robotic approach than the LESS approach. The patient's postoperative symptomatic dysphagia improved relatively more than after the LESS approach. The vast majority of patients who underwent the LESS approach enjoyed improved cosmesis, thus, making LESS a stronger candidate for more routine operations. Despite patient selection bias, the robotic and LESS approaches to anti-reflux operations are safe, efficacious, and should be situationally utilized.

Learning curves and procedural times in Senhance®-robotic assisted fundoplication: results from 237 consecutive patients undergoing robotic fundoplication in a single center as part of the European TRUST Robotic Surgery Registry Study

BACKGROUND

Gastroesophageal reflux disease requiring an operative solution is common. Minimally invasive surgery to generate an anti-reflux barrier at the distal esophagus following the principle of the "floppy Nissen" technique has become the gold standard. Advanced robotic-assisted systems may deliver more consisted outcomes.

METHODS

This registry study analyzed safety and efficacy of the Senhance® surgical system in the surgical treatment of reflux disease and procedural proficiency. Data from 237 consecutive patients operated in a single center were evaluated. Historic standard laparoscopies from the same center were analyzed to compare robotic surgery learning curve effects.

RESULTS

Using the Senhance® Surgical System, during the first 50 patients there was a significant decrease in surgery time which was maintained over the duration of study, pointing to the surgical staff's system-specific learning. After this phase, procedural times were comparable between the robotic-assisted and traditional laparoscopic surgery. The effect of learning was greater than for standard laparoscopy. For 237 patients, there were four conversions to laparoscopic surgery. Two serious adverse events were recorded, both cardiac in nature and not related to the use of the robot.

CONCLUSIONS

Robotic fundoplication was swiftly implemented in a non-university hospital with 65 surgical beds. The operating time was no longer than in standard laparoscopy, the procedure was more standardized than open or laparoscopic surgery and hospitalization times may have been sustainably shortened. The autonomy at the system's digital platform (cockpit) to conduct robotic fundoplications is a big step forward in surgery.

Robotic revision surgery after failed Nissen anti-reflux surgery: a single center experience and a literature review

BACKGROUND

The gastroesophageal reflux disease (GERD) worldwide prevalence is increasing maybe due to population aging and the obesity epidemic. Nissen fundoplication is the most common surgical procedure for GERD with a failure rate of approximately 20% which might require a redo surgery. The aim of this study was to evaluate the short- and long-term outcomes of robotic redo procedures after anti-reflux surgery failure including a narrative review.

METHODS

We reviewed our 15-year experience from 2005 to 2020 including 317 procedures, 306 for primary, and 11 for revisional surgery.

RESULTS

Patients included in the redo series underwent primary Nissen fundoplication with a mean age of 57.6 years (range, 43-71). All procedures were minimally invasive and no conversion to open surgery was registered. The meshes were used in five (45.45%) patients. The mean operative time was 147 min (range, 110-225) and the mean hospital stay was 3.2 days (range, 2-7). At a mean follow-up of 78 months (range, 18-192), one patient suffered for persistent dysphagia and one for delayed gastric emptying. We had two (18.19%) Clavien-Dindo grade IIIa complications, consisting of postoperative pneumothoraxes treated with chest drainage.

CONCLUSION

Redo anti-reflux surgery is indicated in selected patients and the robotic approach is safe when it is performed in specialized centers, considering its surgical technical difficulty.
