Supplemental Digital Content is available in the text Objective: To describe the outcomes of RVHR with varying prosthetic reinforcement techniques. Summary of Background Data: As a recent addition to minimally invasive hernia repair, more data is needed to establish the long-term benefits of RVHR and to identify potential predictors of adverse outcomes. Methods: Patients who underwent RVHR over a 7-year period were evaluated. Robotic intraperitoneal onlay mesh (rIPOM), transabdominal preperitoneal (rTAPP), Rives-Stoppa (rRS), and transversus abdominis release (rTAR) techniques were compared. The main outcomes were 90-day FFC, and 5-year FFR, depicted through Kaplan-Meier curves stratified by repair type and date. Results: A total of 644 RVHRs were analyzed; 197 rIPOM, 156 rTAPP, 153 rRS, and 138 rTAR. There was a gradual transition from intraperitoneal to extraperitoneal mesh placement across the study period. Although rTAPP had the highest 90-day FFC (89.5%) it also had the lowest 5-year FFR (93.3%). Conversely, although rTAR demonstrated the lowest FFC (71%), it had the highest FFR (100%). Coronary artery disease, lysis of adhesions, incisional hernia, and skin-to-skin time (10 minutes. increment) were significant predictors of 90-day complications. Incisional hernia was the sole predictor of 5-year recurrence. Conclusions: This study provides an in-depth perspective of the largest series of RVHR. Based on this experience, rTAPP is no longer recommended due to its limited applicability and high recurrence rate. Both rIPOM and rRS offer encouraging short- and long-term outcomes, while rTAR is associated with the highest perioperative morbidity. Longer follow-up is needed to assess rTAR durability, despite a promising recurrence profile. [ABSTRACT FROM AUTHOR]

Introduction: We assessed whether postoperative day-1 (POD-1) complete blood count (CBC) test parameters, including red cell distribution width (RDW), mean platelet volume (MPV), plateletcrit (PCT), platelet-to-lymphocyte ratio (PLR), and neutrophil-to-lymphocyte ratio (NLR), could identify patients with gastric leaks after laparoscopic sleeve gastrectomy (LSG)., Methods: Patients with postoperative gastric leaks (n=36) and patients with no complications who were selected by age-sex-BMI matching (n=254) were included in the study. The levels of RDW, MPW, PCT, PLR, and NLR were compared between groups in univariate analyses. Receiver operating characteristic (ROC) curve analysis was run for CBC parameters with a P-value<0.05 in univariate analyses. The area under the curve (AUC) was evaluated, and a cutoff value was determined. Sensitivity, specificity, likelihood ratio (LR), positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated., Results: The level of PCT was significantly lower, while levels of PLR and NLR were significantly higher in patients with postoperative gastric leaks as compared with those without (P<0.05). The AUC of both PCT and PLR was <0.750, while the AUC of NLR was 0.911. NLR cutoff at 3.6 yielded 80% sensitivity, 92% specificity, and an LR of 10. In the study cohort, PPV of 59%, NPV of 97%, and an accuracy of 90% were found., Conclusions: Our results suggest that NLR at POD-1, with a cutoff value of 3.6, is a useful indicator of postoperative gastric leak who underwent LSG. We recommend the use of this easily calculated parameter in clinical practice., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: Cumulative sum (CUSUM) learning curves (LCs) are useful to analyze individual performance and to evaluate the acquisition of new skills and the evolution of those skills as experience is accumulated. The purpose of this study is to present a CUSUM LC based on the operative times of robotic intraperitoneal onlay mesh (rIPOM) ventral hernia repair (VHR) and identify differences observed throughout its phases., Materials and Methods: Patients who underwent rIPOM repair for elective, midline, and primary hernias were included. All procedures were performed exclusively by one surgeon within a 5-year period. CUSUM and risk-adjusted CUSUM were used to visualize the LC of rIPOM-VHR, based on operative times and complications. Once groups were obtained, univariate comparisons were performed., Results: Of the 90 rIPOM repairs, 25, 40, and 25 patients were allocated using a CUSUM analysis to the early, middle, and late phases, respectively. In terms of skin-to-skin times, the middle phase has a mean duration of 23 minutes shorter than the early phase (P<0.001), and the late phase has a mean duration 34 minutes shorter than the early phase (P<0.001). A steep decrease in off-console time was observed, with a 10-minute difference from early to middle phases. A consistent and gradual decrease in operative times was observed after completion of 36 cases, and a risk-adjusted CUSUM revealed improving outcomes after 55 cases., Conclusions: This study demonstrates and elucidates interval improvement in operative efficiency in rIPOM-VHR. Consistently decreasing operative times and simultaneous accumulated complication rates were observed after the completion of 55 cases., Competing Interests: O.Y.K. has received a teaching course and consultancy fees from Intuitive Surgical and W.L.
