RESUMO
Over the past 2 decades, the use and importance of robotic surgery in minimally invasive surgery has increased. Across various surgical specialties, robotic technology has gained popularity through its use of 3D visualization, optimal ergonomic positioning, and precise instrument manipulation. This growing interest has also been seen in acute care surgery, where laparoscopic procedures are used more frequently. Despite the growing popularity of robotic surgery in the acute care surgical realm, there is very little research on the utility of robotics regarding its effects on health outcomes and cost-effectiveness. The current literature indicates some value in utilizing robotic technology in specific urgent procedures, such as cholecystectomies and incarcerated hernia repairs; however, the high cost of robotic surgery was found to be a potential barrier to its widespread use in acute care surgery. This narrative literature review aims to determine the cost-effectiveness of robotic-assisted surgery (RAS) in surgical procedures that are often done in urgent settings: cholecystectomies, inguinal hernia repair, ventral hernia repair, and appendectomies.

BACKGROUND: This study aims to compare clinical outcomes and financial cost of intraperitoneal onlay mesh (IPOM) versus retromuscular (RM) repairs in robotic incisional hernia repairs (rIHR). METHODS: Patients who underwent either IPOM or RM elective rIHR from 2012 to 2022 were included. Demographics, operative details, postoperative outcomes, and hospital costs were directly compared. RESULTS: Sixty-nine IPOM and 55 RM were included. Age and body mass index (BMI) did not differ between both groups (IPOM vs RM: 59.3 ± 11.2 years vs. 57.5 ± 14 years, p = 0.423; BMI 34.1 ± 6.3 vs. BMI 33.2 ± 6.9, p = 0.435, respectively). Comorbidities and hernia characteristics were comparable. Extensive lysis of adhesions (> 30 min) was required more often in IPOM (18 vs. 6 in RM, p = 0.034). Defect closure was achieved in 100% of RM vs. 81.2% in IPOM (p < 0.001). Median (interquartile range) postoperative pain score was higher in RM than in IPOM [5(3-7) vs. 4(3-5), respectively, p = 0.006]. Median length of stay (0 day) and same-day discharge rate did not differ between groups (p = 0.598, p = 0.669, respectively). Six (8.7%) patients in the IPOM group versus one (1.8%) patient in the RM group were readmitted to hospital within 30 days postoperatively (p = 0.099). Perioperative complications were higher in IPOM (p = 0.011; 34.8% vs. 14.5% in RM) with higher Comprehensive Complication Index® morbidity scores [0(0-12.2) vs 0(0-0) in RM, p = 0.008)], Clavien-Dindo grade-II complications (8 vs 0 in RM, p = 0.009), and surgical site events (17 vs. 5 in RM, p = 0.024). Within a follow-up period of 57(± 28) months, recurrence rates were similar between both groups. Hospital costs did not differ between groups [IPOM: $9978 (7031-12,926) vs. RM: $8961(6701-11,222), p = 0.300]. Although postoperative complication costs were higher in IPOM ($2436 vs RM: $161, p = 0.020), total costs were comparable [IPOM: $12,415(8700-16,130) vs. RM: $9123(6789-11,457), p = 0.080]. CONCLUSION: Despite retromuscular repairs having lower postoperative complications than intraperitoneal onlay mesh repairs, both techniques offered encouraging results in robotic incisional hernia repair at a comparable total cost.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic strained the health care sector, putting severe constraints on surgical departments. In this study, we evaluate the impact of the pandemic on the outcomes of patients undergoing robotic cholecystectomy (RC). PATIENTS AND METHODS: Patients who underwent RC 1 year before and after March 2020 were included in this retrospective study and assigned accordingly to the pre or post-COVID group. Pre, intra, and postoperative variables were compared between groups. RESULTS: In total, 110 patients were assigned to the pre-COVID group versus 80 in the post-COVID group. There were no differences in the demographics, except for a higher rate of previous gallbladder disease in the pre-COVID group (35.5% vs 13.8,% P < 0.001). The post-COVID group had a higher rate of emergent RCs (62.5% vs 39.1%, P = 0.002). Operative times were greater in the post-COVID group due to the more frequent participation of clinical fellows in the cases. The median hospital length of stay for both groups was 1 day, with higher rates of same-day discharge (pre-COVID 40.9% vs post-COVID 57.5%, P = 0.028). Complications were comparable between both groups, with no recorded cases of COVID-19 contraction within the virus incubation period. The median follow-up was 10 months for the entire cohort. CONCLUSION: During the COVID-19 pandemic, an increase in emergent cases, as well as higher rates of same-day discharge, were recorded, with no impact on postoperative outcomes in patients undergoing RC.

The purpose of this study is to compare the clinical outcomes of robotic ventral hernia repair (RVHR) between smokers and non-smokers. Data for patients undergoing RVHR between 2012 and 2022 were collected. Patients were assigned to either smoking (+) or smoking (-) groups, according to their smoking status in the last 3 months prior to their procedure. Pre-, intra- and postoperative variables including surgical site occurrences (SSO) and infections (SSI), and hernia recurrence were analyzed after a propensity score matching analysis based on the patients' demographics and hernia's characteristics. Each group consisted of 143 patients matched according to their preoperative characteristics. There were no differences in terms of demographics and hernia characteristics. Intraoperative complications occurred at a comparable rate between both groups (p = 0.498). Comprehensive Complication Index® and all complication grades of the Clavien-Dindo classification were similar between both groups. Surgical site occurrences and infections did not differ either [smoking (+) vs. smoking (-): 7.6% vs 5.4%, p = 0.472; 5 vs. 0, p = 0.060, respectively). Rates of SSOs and SSIs that required any intervention (SSOPI) were similar in both groups [smoking (+): 3.1% vs. smoking (-): 0.8%, p = 0.370]. With a mean follow-up of 50 months for the cohort, recurrences rates were also comparable with 7 recorded in the smoking (-) versus 5 in the smoking (+) group (p = 0.215). Our study showed comparable rates of SSOs, SSIs, SSOPIs, and recurrence between smokers and non-smokers following RVHR. Future studies should compare the open, laparoscopic, and robotic approaches in smokers.

OBJECTIVE: To establish the learning curve of multiport robotic cholecystectomy (MRC). PATIENTS AND METHODS: A retrospective analysis of patients undergoing MRC was performed. A cumulative sum analysis helped define the learning curve through the evaluation of skin-to-skin (STS) time and postoperative complications rate. Direct comparison of variables was conducted between the phases. RESULTS: Two hundred forty-five MRC cases were included. Average STS and console times were 50.6 and 29.9 minutes, respectively. Cumulative sum analysis established 3 phases with inflection points at cases 84th and 134th. A significant decrease in STS time was observed between the phases. Middle and late phases encompassed patients with higher comorbidities. Two conversions to open were recorded in the early phase. Postoperative complication rates were comparable among the early (2.5%), middle (6.8%), and late (5.6%) phases ( P = 0.482). CONCLUSION: A steady decrease in STS time was observed across the 3 different phases established at the 84th and 134th patients.

BACKGROUND: Minimally invasive surgery has significantly improved cosmesis and clinical outcomes after either laparoscopic or robotic cholecystectomy. In an effort to minimize the number of incisions in multiport procedures, single-site approaches have been developed. However, single-site robotic cholecystectomy (SSRC) can be technically challenging for novice surgeons. The goal of this study is to establish the learning curve (LC) of SSRC through an assessment of operative times and clinical outcomes. MATERIALS AND METHODS: A retrospective analysis of patients undergoing SSRC over a period of 5 years was performed. Consecutive cholecystectomy cases were assessed based on the procedure setting (elective vs. emergent). Cumulative sum analysis were used to establish the LC through an evaluation of the skin-to-skin (STS) time and postoperative complications rate. Afterward, a direct comparison was performed between the established phases. RESULTS: This study included a total of 259 SSRCs with an overall mean STS time of 41.1 minutes. Elective cases took on average of 38.8 minutes, whereas emergent cases spanned over 60.5 minutes ( P= 0.005). The cumulative sum-LC was obtained by summing the differences between each procedure's STS time, revealing a quadratic best-fit line maximum and an inflection point between the early and late phases at case 91. A significant difference between STS time was seen between the early and late phases (53.8 vs. 30.0 min, P< 0.0001). There were no significant differences in terms of postoperative complications between the 2 phases. Incisional hernia rates were comparable between the 2 phases (early: 4.4% vs. late: 2.5%, P< 0.461). CONCLUSIONS: This is the largest study to assess the LC of SSRC through operative time and clinical outcomes. A steady decrease in STS time was observed during the completion of the first 91 consecutive cases.

BACKGROUND: We sought to study the impact of antithrombotics(antiplatelets and anticoagulants) on robotic ventral hernia repair(RVHR). METHODS: RVHR cases were divided into antithrombotic (AT) (-) and AT (+) groups. After comparing both groups, a logistic regression analysis was performed. RESULTS: 611 patients had no AT-medication. The AT(+) group had 219 patients of which 153 were only on antiplatelets, 52 only on anticoagulants, and 14(6.4%) patients on both antithrombotics. Mean age, American Society of Anesthesiology scores, and comorbidities were significantly higher in the AT(+) group. Intraoperative blood loss was greater in the AT(+) group. Postoperatively, the AT(+) group had greater rates of Clavien-Dindo grade-II and IV-a complications(p=0.001, and p=0.013, respectively), and postoperative hematomas(p=0.013). Mean follow-up was greater than 40 months. Age[Odds Ratio(OR): 1.034] and anticoagulants(OR: 3.121) were associated with increased bleeding-related events. CONCLUSION: There were no associations between maintained antiplatelet therapy and postoperative bleeding-related events in RVHR whereas age and anticoagulants had the highest association.

BACKGROUND: Ventral hernia remains as one of the most performed procedures worldwide. With the aging of the population and increasing comorbidities, it is common for ventral hernia to coexist with other pathologies that require surgery. Patients may opt for concomitant repairs while undergoing ventral hernia surgery. Therefore, the purpose of this study is to investigate the clinical outcomes of robotic ventral hernia repair (RVHR) in patients undergoing concomitant repairs. MATERIALS AND METHODS: Patients who underwent RVHR with concomitant repairs over a period of 9 years were included in this retrospective study. Pre, intra, and postoperative variables including the patient's demographics, hernia characteristics, complications, and hernia recurrence were reported. Univariate analysis was performed to evaluate potential variables associated with increased risk of postoperative complications. RESULTS: A total of 109 (33% females) patients were included in this study. Mean age and body mass index were 59.9±12.7 years and 30.5±5.7 kg/m 2 , respectively. Concomitant repairs were mostly abdominal wall procedures (inguinal hernia repairs, 88.1%). Other procedures included nonabdominal wall surgeries. Incisional hernia repairs were higher than primary repairs (55% vs 45%, respectively). Median operative time and hospital length of stay were 145 min (102 to 245) and 1 day (0 to 1), respectively. Mean postoperative follow-up was 39.2 (4.1 to 93.6) months. In total, 24 patients had postoperative complications, out of which 16 (14.7%) were Clavien-Dindo grade I and II, and 10 (9.2%) were grade III and IV. Nine patients had surgical site events, and two recurrences were recorded. Postoperative complications were associated with incisional hernias [Odds ratio (OR)=8.4; P =0.003; 95% CI=2.092-33.423], nonabdominal wall concomitant procedures (OR=5.9; P =0.013; 95% CI=1.453-24.451), and history of wound infection (OR=3.473; P =0.047; 95% CI=1.016-11.872). CONCLUSIONS: This is the first study to report outcomes of concomitant repairs with RVHR, with notable Clavien-Dindo grade III and IV complications of 9%. Incisional hernia repairs, nonabdominal wall procedures, and a history of wound infection were risk factors for postoperative complications.

BACKGROUND: As robotic ventral hernia repair(VHR) adoption increases, real-world evidence is needed to ensure appropriate utilization. METHODS: Data for open and robotic VHR(OVHR, RVHR) was retrospectively analyzed. Outcomes and costs were compared via inverse probability treatment weighting using propensity scores to estimate the average treatment effect on the treated for RVHR. RESULTS: 675 open and 609 robotic ventral hernia repairs were included. Demographics and hernia characteristics were comparable. Complications rates were lower in RVHR(p < 0.001). Clavien-Dindo grade-III complications were lower in RVHR(13.2% vs. 4.9%, p < 0.001). RVHR resulted in fewer surgical site events(21.5% vs. 12.2%, p < 0.001). Recurrence rates were greater in OVHR(8.9% vs. 2.8%, p < 0.001). The higher RVHR hospital costs (Δ = $2456, p = 0.005) were balanced by the lower post-discharge costs, compared to OVHR(Δ = $799, p = 0.023). Total costs did not differ(Δ = $1656 p = 0.081). CONCLUSION: Although hospital costs were higher, post-discharge expenses favored RVHR due to the lower postoperative complications, which lead to comparable total costs to OVHR.

The aim of this study was to compare the clinical outcomes and hospital costs associated with two different meshes in robotic transabdominal preperitoneal inguinal hernia repair (IHR). Patients who underwent IHR were assigned to either the polyester self-gripping (PSG) or the polypropylene (PP) group depending on the mesh used. A propensity score matching analysis was performed to obtain balanced populations. Postoperative variables included complications such as surgical site events and recurrences. Hospital costs included all possible expenses generated by the surgery during the hospitalization period. From a database of IHR performed between February 2012 and July 2022, 131 PSG patients were matched to 131 PP repairs. Median operative time was shorter in the PSG group [55 (40-78) vs. 80 (60-116) minutes, p < 0.001]. No intraoperative complications were recorded. Patients who received the PSG mesh experience reduced immediate postoperative pain compared to the PP group. Average follow-up time was 35.2 months in the PSG group vs. 12.5 months in the PP group (p < 0.001). Median Comprehensive Complication Index was comparable in both groups (p = 0.489), with no surgical site infections logged. No cases of chronic pain were noted. Only two recurrences were recorded in the cohort, both of them in the PSG repairs. Hospital costs were USD $232 higher in the PP group but did not statistically differ (p = 0.523). There were no differences between the polyester self-gripping and the polypropylene mesh in terms of postoperative complications, clinical outcomes and hospital costs. Surgeons may opt for either meshes depending on their preferences and familiarity with each of the products.

BACKGROUND: Although the advantages of laparoscopic inguinal hernia repair (LIHR) have been described, guidelines regarding robotic inguinal hernia repair (RIHR) have yet to be established, despite its increased adoption as a minimally invasive alternative. This study compares the largest single-center cohorts of LIHR and RIHR and aims to shed light on the differences in outcomes between these two techniques. METHODS: Patients who underwent LIHR or RIHR over an 8-year period were included as part of a retrospective analysis. Variables were stratified by preoperative, intraoperative, and postoperative timeframes. Complications were listed according to the Clavien-Dindo classification system and comprehensive complication index (CCI®). Study groups were compared using univariate analyses and Kaplan-Meier's time-to-event analysis. RESULTS: A total of 1153 patients were included: 606 patients underwent LIHR, while 547 underwent RIHR. Although demographics and comorbidities were mostly similar between the groups, the RIHR group included a higher proportion of complex hernias. Operative times were in favor of LIHR (42 vs. 53 min, p < 0.001), while RIHR had a smaller number of peritoneal breaches (0.4 vs. 3.8%, p < 0.001) as well as conversions (0.2 vs. 2.8%, p < 0.001). The number of patients lost-to-follow-up and the average follow-up times were similar (p = 0.821 and p = 0.304, respectively). Postoperatively, CCI® scores did not differ between the two groups (median = 0, p = 0.380), but Grade IIIB complications (1.2 vs. 3.3%, p = 0.025) and recurrences (0.8% vs. 2.9%, p = 0.013) were in favor of RIHR. Furthermore, estimated recurrence-free time was higher in the RIHR group [p = 0.032; 99.7 months (95% CI 98.8-100.5) vs. 97.6 months (95% CI 95.9-99.3). CONCLUSION: This study demonstrated that RIHR may confer advantages over LIHR in terms of addressing more complex repairs while simultaneously reducing conversion and recurrence rates, at the expense of prolonged operation times. Further large-scale prospective studies and trials are needed to validate these findings and better understand whether RIHR offers substantial clinical benefit compared with LIHR.

Background: Advancement in surgery has shifted numerous procedures to a same-day discharge (SDD) setting. In this study, we evaluated factors related to SDD after robotic transversus abdominis release (rTAR). Materials and Methods: A retrospective analysis of a prospectively maintained hernia databank was performed. Patients who underwent rTAR for incisional hernias were assigned to either the SDD group (length of stay [LOS] <1) or the inpatient group (LOS ≥1 day). Pre-, intra-, and postoperative variables were compared. Predictors of SDD were explored through a logistic regression, and a mediation analysis was performed to assess their effect on the LOS. Results: Out of the 167 patients included, 53 patients were discharged the same day. Age, American Society of Anesthesiologists score, history of coronary artery disease, and wound infection were significantly higher in the inpatient group. Overall, median LOS was 1 (0-2). Postoperative complications did not differ between SDD and inpatient groups except for Clavien-Dindo Grade-II (1 versus 14, respectively; P = .039). Thirty-day readmission rates were comparable (P = .229). A binary logistic regression to predict factors associated with SDD rTAR showed statistical significance in age, operative time, mesh area, and history of wound infection. Mediation analysis showed that mesh size indirectly affected the LOS through the operative time (a = 0.54; b = 0.46; P < .001). An age >46-year-old, an operative time beyond 217 minutes, and a mesh size >475 cm2 increased the probability of an inpatient stay (area-under-the-receiver operating characteristic curves: 0.69, 0.81, and 0.82, respectively). Conclusion: The pre- and intraoperative factors associated with SDD rTAR were age, history of wound infection, operative time, and mesh area. Further studies are needed to investigate the appropriateness of discharge decisions while balancing patients' benefits, resource utilization, and costs.

BACKGROUND: The COVID-19 pandemic disrupted the healthcare sector and forced hospitals to limit the number of elective procedures with the goal of reducing overcrowding of wards and thus viral transmission. Recent trends for ventral hernia repair have shifted towards retromuscular techniques, which normally require a longer length of stay. Therefore, the aim of this study is to investigate the impact of the COVID-19 pandemic on clinical outcomes of robotic retromuscular ventral hernia repair (rRVHR). METHODS: Patients who underwent rRVHR up to 600 days before and after March 10, 2020, were included in this retrospective study and assigned to the pre- or post-COVID group depending on the date of their procedure. Pre-, intra-, and postoperative variables including patients' demographics, hernia characteristics, complications, and hernia recurrence were compared between both groups. RESULTS: 153 (46% female) and 141 (51% female) patients were assigned to the pre- and post-COVID groups respectively. Median age was statistically different between both groups [pre-COVID: 57 (48-68) vs. post-COVID 55 (42-64) years, p = 0.045]. Median hospital length of stay (LOS) was 0 day (0-1) in both groups, and same day discharge were 61% pre-pandemic and 70% post-pandemic (p = 0.09). Mean postoperative follow-up was 39.2 (4.1-93.6) months. In total, 26 pre-COVID patients had postoperative complications, out of which 7 were pulmonary complications, whereas 23 complications were recorded in the post-COVID group, with only 3 pulmonary complications (p = 0.88). Rate of surgical-site events was comparable between both groups, and no recurrences were recorded. CONCLUSION: This is the first study to describe the impact of the COVID-19 on rRVHR. Hospital LOS was comparable between both groups. Rates of medical and hernia specific complications were not altered by the pandemic.

PURPOSE: The purpose of this study is to prospectively evaluate surgical and quality of life (QoL) outcomes of robotic retromuscular ventral hernia repair (rRMVHR) using a new hybrid mesh in high-risk patients. METHODS: Data was prospectively collected for patients classified as high-risk based on the modified ventral hernia working group (VHWG) grading system, who underwent rRMVHR using Synecor™ Pre hybrid mesh in a single center, between 2019 and 2020. Pre-, intra- and postoperative variables including hernia recurrence, surgical site events (SSE), hernia-specific quality of life (QoL), and financial costs were analyzed. QoL assessments were obtained from preoperative and postoperative patient visits. Kaplan-Meier survival analysis was performed to analyze the estimated recurrence-free time. RESULTS: Fifty-two high-risk patients, with a mean (±SD) age of 58.6 ± 13.7 years and BMI of 36.9 ± 6.6 kg/m2, were followed for a mean (±SD) period of 22.4 ± 7.1 months. A total of 11 (21.2%) patients experienced postoperative complications, out of which eight were SSEs, including 7 (13.5%) seromas, 1 (1.9%) hematoma, and no infections. Procedural interventions were required for 2 (3.8%) surgical site occurrences. Recurrence was seen in 1 (1.9%) patient. The estimated mean (95% confidence interval) recurrence-free time was 33 (32.3-34.5) months. Postoperative QoL assessments demonstrated significant improvements in comparison to preoperative QoL, with a minimum ∆mean (±SD) of -15.5 ± 2.2 at one month (p < 0.001). The mean (±SD) procedure cost was $13,924.18 ± 7856.95 which includes the average mesh cost ($5390.12 ± 3817.03). CONCLUSION: Our study showed favorable early and mid-term outcomes, in addition to significant improvements in QoL, after rRMVHR using Synecor™ hybrid mesh in high-risk patients.

Background and Objectives: To estimate the average treatment effect on the treated (ATT) and to assess the clinical outcomes in two different types of mesh in robotic Rives-Stoppa (rRS) ventral hernia repair (VHR). Methods: A retrospective analysis of a robotic VHR database between February 1, 2013 and May 31, 2022. Patients who underwent a rRS VHR were included in this study and separated into two groups depending on the mesh used: SynecorTM Preperitoneal Biomaterial (SynecorTM Pre) and Bard™ Soft. Through propensity score and inverse-probability-treatment-weighting, the ATT was estimated for two scenarios; the first with the treated target having used the SynecorTM Pre, the second having used the Bard™ Soft mesh. Adjusted linear regression models, including lingering imbalanced variables, were used for both the primary outcome of the Comprehensive Complication Index (CCI®), and the secondary outcome of the hospital cost. Results: A total of 186 patients who underwent rRS were separated into the two groups (SynecorTM Pre mesh, n = 85; Bard™ Soft mesh, n = 101). Adjusted linear regression models for the CCI showed no statistical difference between both groups (p > 0.05), whereas ATT on hospital cost was significantly higher (p < 0.001) in the SynecorTM Pre group in both scenarios [(95% confidence interval) = 3882 (2352, 5413) and -5185 (-8213, -2157), respectively]. Conclusion: Both mesh materials provided excellent outcomes with no difference in complications or recurrence rates. However, hospital cost was found to be higher in the hybrid mesh group. Long-term follow-up is needed to fully assess the performance of both mesh types in rRS.

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 (10âminutes. 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.

BACKGROUND: Robot-assisted transabdominal preperitoneal inguinal hernia repair (rTAPP-IHR) is a safe and feasible approach for hernias of varying etiology. We aim to present a single surgeon's learning curve (LC) of this technique based on operative times, while accounting for bilaterality and complexity. METHODS: This is a retrospective cohort analysis of patients who underwent rTAPP-IHR over a period of 5 years. Patients who underwent primary, recurrent, and complex (previous posterior repair, previous prostatectomy, scrotal, incarcerated) repairs were included. Cumulative and risk-adjusted cumulative sum analyses (CUSUM and RA-CUSUM) were used to depict the evolution of skin-to-skin times and complications/surgical site events (SSEs) with time, respectively. RESULTS: A total of 371 patients were included in the study. Mean skin-to-skin times were stratified according to four subgroups: unilateral non-complex (46.8 min), unilateral complex (63.2 min), bilateral non-complex (70.9 min), and bilateral complex (102 min). A CUSUM-LC was then plotted using each procedures difference in operative time from its subgroup mean. The peak of the plot occurred at case number 138, which was used as a transition between 'early' and 'late' phases. The average operative time for the late phase was 15.9 min shorter than the early phase (p < 0.001). The RA-CUSUM, plotted using the weight of case complexity and unilateral/bilateral status, also showed decreasing SSE rates after the completion of 138 cases (early phase: 8.8% vs. late phase: 2.2%, p = 0.008). Overall complication rates did not differ significantly between the two phases. CONCLUSIONS: Our study shows that regardless of bilateral or complex status, rTAPP operative times and SSE rates gradually decreased after completing 138 procedures. Previous laparoscopic experience, robotic team efficiency, and surgical knowledge are important considerations for a surgeon's LC.

BACKGROUND: Despite heightened interest in robotic transversus abdominis release (rTAR), concerns over its steep learning curve (LC) and associated challenges may limit its adoption. This study defines the operative time and morbidity-based LC of a single surgeon's experience with rTAR. METHODS: A retrospective analysis of patients undergoing rTAR over an 8-year period was conducted. Consecutive ventral and incisional hernia repairs were stratified into four sub-categories based on bilaterality and complexity, with complex hernias being defined as those > 10 cm. Cumulative sum analyses (CUSUM) were used to evaluate skin-to-skin time and morbidity LCs. RESULTS: This study included a total of 156 rTARs with a mean skin-to-skin time of 222.8 min. Mean skin-to-skin times (min) for sub-categories were as follows: unilateral non-complex (137.6), bilateral non-complex (206.8), unilateral complex (241.9), and bilateral complex (298.6). The CUSUM-LC was obtained by summing the differences between each procedure's operative time and its sub-category mean, revealing a quadratic best-fit line maximum at case 49 and a transition point between early and late phases at case 75. Although skin-to-skin times between early and late phases did not differ significantly (235.3 vs 211.2, respectively; p = 0.12), a significant difference was found in console times. Overall postoperative complications also decreased significantly from early to late phases (41.3% vs 25.9%; p = 0.041). Postoperative complications were predicted by a history of wound infection (c = 0.61). CONCLUSIONS: This study reveals that the rTAR LC was overcome between 49 and 75 cases, after which, console time and postoperative complications decreased significantly.

BACKGROUND: Obese patients have an increased incidence of ventral hernias; in over 50% of these cases, patients are symptomatic. At the same time, morbid obesity is a disease of epidemic proportions. The combination of symptomatic hernia and obesity is a challenge for the treating surgeon, because the risk of perioperative complications and recurrence increases with increasing BMI. SUMMARY: This review outlines this problem and discusses interdisciplinary approaches to the management of affected patients. In emergency cases, the hernia is treated according to the surgeon's expertise. In elective cases, an individual decision must be made whether bariatric surgery is indicated before hernia repair or whether both should be performed simultaneously. After bariatric surgery a weight reduction of 25-30% of total body weight in the first year can be achieved and it is often advantageous to perform a bariatric operation prior to hernia repair. Technically, the risk of complications is lower with minimally invasive procedures than with open ones, but laparoscopy is challenging in obese patients, and meshes can only be implanted in intraperitoneal position. This mesh position has to be questioned because of adhesions, recurrence rate, and risk of contamination during re-interventions in patients who are often still relatively young. KEY MESSAGES: Obese patients with hernia need to be approached in an interdisciplinary manner, in some patients a weight loss procedure may be advantageous before hernia repair. Recent data show the benefits of robotic hernia surgery in obese patients, as not only haptic advantages result, but especially the mesh can be implanted in a variety of extraperitoneal positions in the abdominal wall with low morbidity.
RESUMO
BACKGROUND: Closure of the direct inguinal defect with plication in minimally invasive direct inguinal hernia repair may have potential benefits in terms of reducing postoperative surgical site events (SSEs) and recurrences. However, these advantages remain unclear, particularly in the robotic literature. This is the first comparative study to investigate the outcomes after robotic direct inguinal hernia repair (RDIHR) with defect plication. MATERIALS AND METHODS: Among patients who underwent RIHR between 2013 and 2020, those who underwent RDIHR were selected. Patients were then stratified into 2 groups based on defect plication status, and univariate analyses were used to compare variables across preoperative, intraoperative, and postoperative timeframes. RESULTS: A total of 225 RDIHRs were performed in 176 patients, where 74 were assigned to the Plication (+) group and 102 patients were assigned to the Plication (-) group. There was a significantly higher proportion of females in the Plication (-) group (10.8% vs. 1.4%, P=0.015), which accounts for the higher incidence of accompanying femoral hernias in this group. While most M1 hernia defects were left patent, most M2 and M3 hernias were plicated. Larger mesh sizes were used in the Plication (+) group (P<0.001). Three SSEs were observed in the Plication (-) group versus 2 SSEs in the Plication (+) group. No significant differences in postoperative outcomes were found between the 2 groups. CONCLUSIONS: Postoperative seroma incidence, pain scores, and recurrence rates were similar between the 2 study groups. Multicenter studies with larger populations and higher complication counts are needed to establish the role of defect plication in RDIHR.
