Concomitant midline ventral and inguinal hernia repair: can we create an algorithmic approach? Hernia 2024:10.1007/s10029-024-03008-w. [PMID: 38512506 DOI: 10.1007/s10029-024-03008-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2023] [Accepted: 03/01/2024] [Indexed: 03/23/2024]
Abstract
PURPOSE International guidelines exist for surgical treatment of either ventral or inguinal hernias repair (VHR; IHR). However, approach for managing both of them remains unestablished and is further complicated by newly developed surgical techniques and modalities (namely, robotic). This highlights the need for a tailored, algorithmic strategy to streamline surgical management. METHODS An algorithm was developed by the directors of the NYU Langone Abdominal Core Health program of which four treatment groups were described: Group 1: open VHR and either laparoscopic or robotic IHR; Group 2: robotic transabdominal pre-peritoneal (TAPP) approach for both VHR and IHR; Group 3: robotic retro-muscular VHR and IHR; and Group 4: open repair for both. Demographics, comorbidities, operative characteristics, and surgical outcomes from November 2021 to July 2023 were retrospectively compared. RESULTS Ninety-two patients were included with a median age of 64 years, 90% (n = 83) were white, 85% (n = 78) were male, median BMI was 27 kg/m2, and 73% (n = 67) were ASA class II. Distribution of groups was: 48% (n = 44) in 1A, 8% (n = 7) in 1B, 8% (n = 7) in 2A, 3% (n = 3) in 2B, 23% (n = 21) in 3A, 8% (n = 7) in 3B, and 3% (n = 3) in 4. Ventral hernia size, OR time, and postoperative length of stay varied across groups. Postoperative outcomes at 30 days including emergency consults, readmissions, and complications, showed no differences across groups. CONCLUSION Access without guidance to new minimally invasive surgical approaches can be a challenge for the general surgeon. We propose an algorithm for decision-making based on our experience of incorporating robotic surgery, when available, for repair of concomitant VHR and IHR with consistent favorable outcomes within a small sample of patients.

Abstract
PURPOSE Thoracoabdominal hernias remain a rare and poorly understood entity. Data remain sparse as terminology varies in the literature and case reports demonstrate wide variability in technique. We present a novel approach for repair of thoracoabdominal hernias using the robotic platform. METHODS Two patients underwent a robotic thoracoabdominal hernia repair in June 2022. They were followed for 1 year with CT scans every 6 months to exclude recurrence. Patient demographics and peri-operative details including defect size, closure technique, mesh size, length of stay, and complications were reported. RESULTS Both patients successfully underwent a robotic repair of a thoracoabdominal hernia, addressing the intercostal hernia, diaphragmatic disruption, and flank hernia discretely during the operation. One patient had an uneventful recovery and discharged on post-operative day 3; the other developed a small bowel obstruction due to an early port site hernia which required surgical intervention. He eventually discharged on post-operative day 9. At one year, there is no clinical or radiographic evidence of recurrence for either patient. CONCLUSION Robotic thoracoabdominal hernia repair is feasible and offers a minimally invasive repair option for these extremely complex hernias.

Robotic approach for retromuscular ventral hernia repair may be associated with improved wound morbidity in high-risk patients: a propensity score analysis. Surg Endosc 2024; 38:1013-1019. [PMID: 38091108 DOI: 10.1007/s00464-023-10630-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Accepted: 11/29/2023] [Indexed: 02/02/2024]
Abstract
BACKGROUND Retromuscular sublay (RMS) technique for repair of ventral hernias has gained popularity due to lower risk of recurrence and wound complications. Robotic approaches to RMS have been shown to decrease hospital stay; however, previous studies have failed to show a significant reduction in wound morbidity. Utilizing the Abdominal Core Health Quality Collaborative (ACHQC) database, this study sought to determine the effect of robotic approach on wound morbidity, while specifically focusing on a high-risk population. METHODS A retrospective review of elective robotic and open RMS repairs in the ACHQC database was performed. Patients deemed to be high-risk for wound complications were included: adult patients with BMI greater than 35 and who were either current smokers or diabetics. A propensity score match was then done to balance covariates between the two groups. Main outcomes of concern were surgical site occurrences (SSO), surgical site infections (SSI), and surgical site occurrence requiring procedural intervention (SSOPI) at 30-day follow-up. RESULTS A total of 917 patients met inclusion criteria. After propensity score matching, 211 patients matched for each approach. There was no difference in overall SSO (18% for Open vs 23% for Robotic, p = 0.23). Open repair was associated with higher rates of SSI (4% vs 1%, p = 0.032) and SSOPI (9% SSOPI vs 3%, p < 0. 015). As seen in previous studies, there was a higher rate of seroma associated with Robotic RMS repair (87% vs 48%, p < 0.001) in patients that developed an SSO. CONCLUSIONS In this analysis, a robotic approach was associated with decreased rates of SSI and SSOPI in obese patients who were either current smokers or diabetics. In effort to reduce wound morbidity and the associated physical and economic costs, robotic approach for retromuscular ventral hernia repair should be considered in this patient population.

S041-Trends and short-term outcomes of three approaches to minimally invasive repair of small ventral hernias. An ACHQC analysis. Surg Endosc 2022:10.1007/s00464-022-09629-5. [PMID: 36163562 DOI: 10.1007/s00464-022-09629-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2022] [Accepted: 09/11/2022] [Indexed: 10/14/2022]
Abstract
INTRODUCTION Different approaches and mesh positions are used for minimally invasive ventral hernia repair (MIS-VHR). Our aim was to evaluate the trends and short-term outcomes of intraperitoneal onlay mesh (IPOM), preperitoneal, and retromuscular repairs for small ventral hernias. METHODS We conducted a retrospective cohort study using the Abdominal Core Health Quality Collaborative (ACHQC). We included elective MIS-VHR in adults with hernia defect width < = 6 cm from 2012 to 2021. We compared patient/hernia characteristics, trends, and short-term outcomes between IPOM, preperitoneal, and retromuscular repairs. Inverse probability of treatment weighting (IPTW) was used to balance baseline characteristics. RESULTS A total of 7261 patients were included (IPOM = 4484, preperitoneal = 1829, retromuscular = 948). Preperitoneal repair was associated with lower rates of incisional (preperitoneal = 37%, IPOM = 63%, retromuscular = 73%) and recurrent hernias (preperitoneal = 11%, IPOM = 21%, retromuscular = 22%) compared to IPOM and retromuscular. Median defect width was 3.0, 2.0, and 4.0 cm for IPOM, preperitoneal, and retromuscular, respectively. There has been a progressive increase in the proportion of preperitoneal and retromuscular repairs over time (10% in 2013-53% in 2021 of all MIS-VHR). Robotic approach was more frequently utilized in preperitoneal and retromuscular (both > 85%) compared to IPOM (47%). Transversus abdominis release was performed in 14% of retromuscular repairs. After IPTW, no clinically significant differences were noted in the short-term outcomes between IPOM versus preperitoneal. Retromuscular repairs were associated with higher risk of 30-day reoperation (OR = 3.54, 95%CI [1.67, 7.5] and OR = 5.29, 95%CI [1.23, 22.74]) compared to IPOM and preperitoneal repairs, respectively, and higher risk of 30-day readmission compared to preperitoneal repairs (OR = 2.6, 95%CI [2.6, 6.4]). CONCLUSION Based on ACHQC data, preperitoneal and retromuscular approaches for MIS-VHR of small hernias have increased over time and are primarily performed robotically. Transversus abdominis release was performed in 14% of retromuscular repairs of these small hernias. Retromuscular repairs were associated with higher 30-day readmission and reoperation rates compared to the other approaches.

Abstract
BACKGROUND The choice of how to repair inguinal hernias in adolescents has historically been a matter of experience and differed between pediatric surgeons who traditionally performed a high ligation of the sac and general surgeons who typically perform a repair using mesh. This up-to-date review thoroughly examines the subject and discusses the suitability of both types of repairs in this unique age group. METHODS A 20-year Pub Med search was performed for the following terms: adolescent hernia repair including reports of mesh hernia repair in adolescents and postoperative complications including chronic inguinal pain and recurrences. RESULTS The evidence in the literature suggests that while there appears to be no difference between the two types of repairs with regards to recurrence and complications, changes in the pelvic floor physiology in adolescents suggest that a selective, individualized approach can be recommended depending on the size and nature of the presenting pathology. CONCLUSIONS A selective approach to the inguinal hernia in adolescent patients based on the size of the defect appears justified.

Abstract
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.

A novel approach for the treatment of Morgagni hernias: robotic transabdominal preperitoneal diaphragmatic hernia repair. Hernia 2021; 26:355-361. [PMID: 34494141 DOI: 10.1007/s10029-021-02472-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Accepted: 07/16/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE We introduce a novel approach to the surgical repair of Morgagni hernias (MHs) utilizing the robotic transabdominal preperitoneal repair (rTAPP) approach. Borrowed from our previous and robust experience with rTAPP repairs for hernias of the anterior abdominal wall, this technique boasts the benefits of hernia sac reduction, the use of an uncoated mesh in an extraperitoneal plane, and minimal fixation leading to lower postoperative pain relative to other approaches. METHODS To evaluate the effectiveness of this novel approach, five consecutive symptomatic Morgagni hernias (MHs) were repaired with the rTAPP approach. The size of the defect, mesh size, length of stay, follow-up imaging, and follow-up complications were documented for comparison. RESULTS The size of the MH defects ranged from 4 × 6 cm to 5 × 10 cm. LOS was an average of 1.2 days. Two out of the five patients underwent concomitant repair of a lower abdominal hernias (one Spigelian hernia, and one indirect inguinal hernia). Outpatient follow-up from surgery ranged anywhere from 6 months to 4 years, with most patients receiving follow-up after 1 year. Four out of the five patients received follow-up CT scans to confirm the absence of hernia recurrence. One patient experienced an incisional hernia from the midline 12-mm port site which was repaired 1 year after. CONCLUSION We propose a new technique for a minimally invasive strategy to treat these complex hernias utilizing an rTAPP technique resulting in minimal length of stay and a durable result in long-term follow-up. The benefits of repair, which include minimal postoperative pain, minimal length of stay, and cost-effective prosthetic mesh hidden from the visceral contents, are consistent with the author's experience for rTAPP repairs for hernias of the anterior abdominal wall.

Abstract
The literature surrounding emergent robotic ventral hernia repair (RVHR) is scarce. We aimed to present the results of 6 years of experience of RVHR in the emergency setting. Data were retrospectively analyzed from patients who underwent RVHR in an emergent setting between 2013 and 2019. Complications were assessed with the Clavien-Dindo (CD) and Comprehensive Complication Index (CCI®) scoring systems. Kaplan-Meier's time-to-event analysis was performed to calculate freedom-of-recurrence. Out of 589 patients who underwent RVHR, 34 patients were included. Median APACHE-II scores were 6.5. The average skin-to-skin time was 139 min. 7/34(20.5%) patients experienced minor complications (CD-grades I-II) and 4/34 (11.7%) patients experienced major complications (CD-grades III-IV). CCI® scores ranged from 0-42.4. Only one (2.9%) patient experienced hernia recurrence. The mean postoperative follow-up was 20.5 (range 1.6-56.3) months. Emergent RVHR showed promising results in terms of midterm outcomes and overall feasibility. RVHR appears to be effective in emergency settings, however, further multicenter studies with long-term follow-up are needed.

Abstract
PURPOSE To review literature surrounding transversus abdominis release (TAR) for incisional hernia repair, with the aim of describing key preoperative and technical considerations for this procedure. METHODS Existing literature on TAR was reviewed and synthesized with the clinical experience and approach to TAR from a high-volume hernia center. RESULTS Recommendations regarding patient selection, optimization and technique for TAR are presented. CONCLUSIONS While published outcomes of TAR from expert centers are favorable, potentially devastating complications may result when TAR is performed incorrectly or in suboptimal clinical situations. Appropriate patient selection, optimization, and surgeon expertise are necessary if TAR is to be performed.

Abstract
BACKGROUND The most common technique described for robotic ventral hernia repair (RVHR) is intraperitoneal onlay mesh (IPOM). With the evolution of robotics, advanced techniques including retro rectus mesh reinforcement, and component separation are being popularized. However, these procedures require more dissection, and longer operative times. In this study we reviewed our experience with robotic ventral/incisional hernia repair (RVHR) with hernia defect closure (HDC) and IPOM. METHODS Retrospective chart review and follow-up of 31 consecutive cases of ventral/incisional hernia treated between August 2011 and December 2018. Demographics, operative times, blood loss, length of stay (LOS), hernia size, location, and type, mesh size and type, recurrence, conversion to open ventral hernia repair (OVHR) and complications including bleeding, seroma formation and infection were analyzed. RESULTS Mean age was 63.9 years old, with median BMI of 31.24 kg/m2. Median hernia area was 17 cm2. Mean operating time was 142.61 min (SD 59.79). Mean LOS was 1.46 days (range 1-5), with 48% being outpatient, and overnight stay in 32% for pain control. Conversion was necessary in 12.9% cases. Complication rate was 3% for enterotomy. Recurrence was 14.81% after a mean follow-up of 26.96 months. There was significant association of recurrence with COPD history (P = 0.0215) and multiple hernia defects (P = 0.0376). CONCLUSION Our recurrence rate (14.81%) compares favorably to those reported in literature (16.7%) for LVHR with HDC and IPOM. Our experience also indicates that IPOM is associated with satisfactory outcomes, low conversion and complications rates, and short LOS.

Abstract
BACKGROUND Short-term success following robotic-assisted ventral hernia repair (RVHR) is well established; however, data describing outcomes after the first year are limited. In this study, we followed a cohort of patients with an average of 1.8 years of follow-up to demonstrate the durability of this technique and examine risk factors for recurrence. METHODS A retrospective analysis of RVHR performed by a single surgeon from 2012 to 2016 was done. The technical approach for hernia repair consisted of tension-free primary fascial closure with placement of preperitoneal mesh when possible. The primary end point of hernia recurrence was determined based on physical examination or imaging documented in the medical record. A logistic regression model was used to identify patient risk factors for recurrence. RESULTS One hundred and eight RVHRs were performed over 4 years. Mean age was 52.72 ± 13.61 years, BMI was 33.07 ± 7.82 kg/m2, and hernia defect size was 70.1 ± 86.3 cm2. In terms of patient characteristics, 17.6% of patients were diabetic, 13.9% were smokers preoperatively, 72.2% were ASA class 3 or higher, and 29.6% had prior VHR. Primary fascial closure was achieved in all RVHRs, with 23.1% requiring component separation. Mesh was used in 97.2% of patients: 79.5% had preperitoneal mesh and 17.6% had intraperitoneal onlay mesh. Ninety-eight percent of patients had long-term follow-up at a mean of 625.6 days. Recurrence rate was 12%, with one recurrence attributed to an inguinal hernia fixed concurrently with a midline defect. There were no statistically significant differences in gender, age, BMI, ASA class, incidence of diabetes, smoking status, or number of previous hernia repairs. Hernia defect size and perioperative complications including SSO, ileus, obstruction, or any other medical complication were not predictive of recurrence. Technical approach did not affect outcomes. CONCLUSION RVHR is safe and durable with a low recurrence rate at a mean of 21 months postoperatively. Patient characteristics or type of repair were not predictive of recurrence.

Abstract
While the majority of the literature written concerning minimally invasive hiatal hernia repair involves laparoscopy, little has been written concerning the transition to a robotic technique. We present our experience, with a transparent analysis of data, with regard to the introduction of robotic paraesophageal hernia (PEH) repair by an experienced laparoscopic surgeon. We reviewed our first 30 consecutive patients who underwent robotic PEH over a 2-year period after the introduction of robotic surgery at our institution. Patients were divided into two groups: the early experience group (procedures performed within the first year of introduction of robotic technique, n = 13) and a late experience group (procedures performed in the second year, n = 17). All procedures were performed by a single experienced foregut surgeon. The mean operative time for the early group was significantly greater than for the late group, 184 min versus 142 min, respectively (p < 0.01). Four patients in the early group required conversion to open, while zero patients in the late group required conversion (p = 0.03). Patient demographics and complications did not differ significantly between the two patient populations. The early robotic hiatal hernia repair experience can be more difficult than expected, even in the hands of an experienced laparoscopic team. We identify several areas of improvement including patient positioning, operating room team training, and technical experience. This data can help other surgeons prepare for the transition to robotic foregut surgery.

Abstract
Background: Robotic complex abdominal wall reconstruction (r-AWR) using transversus abdominis release (TAR) is associated with decreased wound complications, morbidity, and length of stay compared with open repair. This report describes a single-institution experience of r-AWR. Methods: A retrospective chart review was performed on patients who underwent r-AWR by a single surgeon (D.H.) from August 2015 through October 2018. Results: Fifty-five patients underwent r-AWR (16 males [29%] and 39 females [71%]) with a mean age of 60.2 (range 33 to 87) years and a mean body mass index of 34.6 (range 23 to 54) kg/m2. Forty-one patients presented with an initial ventral hernia (74.5%) and 14 with a recurrent hernia (25.5%). Five patients had a grade 1 hernia (9.1%), 46 had a grade 2 hernia (83.6%), and 4 had a grade 3 hernia (7.3%) according to the Ventral Hernia Working Group system. Thirty-four (62%) patients underwent TAR, 21 (38%) patients underwent bilateral retrorectus release, and 10 (18.2%) patients underwent concomitant inguinal hernia repair. Mean operative time with TAR was 294 (range 106 to 472) minutes and 183 (range 126 to 254) minutes without TAR. Mean length of stay was 1.5 (range 0 to 10) days. Mean follow-up was 10.7 (range 1 to 52) weeks with no hernia recurrences. Seromas occurred in 6 (10.9%) patients, with 2 (3.6%) requiring drainage. Two (3.6%) 30-day readmissions occurred with no conversions to open or 30-day mortalities. Conclusions: r-AWR with and without TAR is a safe and feasible procedure associated with a short LOS, low complication rate, and low recurrence even within the surgeon's learning curve experience.

Abstract
Background The true incidence of occult contralateral inguinal hernia is unknown; however, when found, there exists controversy as to whether or not they should be repaired. The aim of our study is to identify the incidence of contralateral incidental inguinal hernias in our surgical population, compare our results to previous studies timelining occult hernia identification to repair need, and generate debate as to whether incidental contralateral hernias should be repaired at the index operation. Methods We reviewed the charts of 297 consecutive patients undergoing robotic inguinal hernia repair between October 2014 and April 2018 at a single facility. By comparing preoperative physical examination to intraoperative findings, we determined the number of occult contralateral inguinal hernias in our patient population. Results Of 297 patients, 158 (53.2%) presented with a right inguinal hernia, 90 (30.3%) presented with a left inguinal hernia, and 49 (16.5%) presented with bilateral inguinal hernias. Forty-seven of the 297 patients (15.8%) were found to have an incidental contralateral inguinal hernia. Excluding patients with known bilateral inguinal hernias, 20% of patients with a left inguinal hernia were found to have an occult right inguinal hernia and 18.4% of patients with a right inguinal hernia were found to have an occult left inguinal hernia. Conclusions The true incidence of occult contralateral inguinal hernia may be higher than originally thought. When inguinal hernia repair is performed through a transabdominal approach, these occult hernias may be easily addressed during the same operation without additional skin incisions. This may ultimately prevent the morbidity of developing a metachronous hernia that requires repair.

Comparative analysis of perioperative outcomes of robotic versus open transversus abdominis release. Surg Endosc 2017; 32:840-845. [PMID: 28733746 DOI: 10.1007/s00464-017-5752-1] [Citation(s) in RCA: 79] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2017] [Accepted: 07/14/2017] [Indexed: 12/27/2022]
Abstract
BACKGROUND Transversus abdominis release (TAR) has evolved as an effective approach to complex abdominal wall reconstructions. Although the role of robotics in hernia surgery is rapidly expanding, the benefits of a robotic approach for abdominal wall reconstruction have not been established well. We aimed to compare the impact of the application of robotics to the TAR procedure on the perioperative outcomes when compared to the open TAR repairs. METHODS Case-matched comparison of patients undergoing robotic TAR (R-TAR) at two specialized hernia centers to a matched historic cohort of open TAR (O-TAR) patients was performed. Outcome measures included patient demographics, operative details, postoperative complications, and length of hospitalization. RESULTS 38 consecutive patients undergoing R-TAR were compared to 76 matched O-TAR. Patient demographics were similar between the groups, but ASA III status was more prevalent in the O-TAR group. The average operative time was significantly longer in the R-TAR group (299 ± 95 vs.. 211 ± 63 min, p < 0.001) and blood loss was significantly lower for the R-TAR group (49 ± 60 vs. 139 ± 149 mL, p < 0.001). Wound morbidity was minimal in the R-TAR, but the rate of surgical site events and surgical site infection was not different between groups. Systemic complications were significantly less frequent in the R-TAR group (0 vs. 17.1%, p = 0.026). The length of hospitalization was significantly reduced in the R-TAR group (1.3 ± 1.3 vs. 6.0 ± 3.4 days, p < 0.001). CONCLUSIONS In our early experience, robotic TAR was associated with longer operative times. However, we found that the use of robotics was associated with decreased intraoperative blood loss, fewer systemic complications, shorter hospitalizations, and eliminated readmissions. While long-term outcomes and patient selection criteria for robotic TAR repair are under investigations, we advocate selective use of robotics for TAR reconstructions in patients undergoing AWR.

Comparative analysis of open and robotic transversus abdominis release for ventral hernia repair. Surg Endosc 2017; 32:727-734. [PMID: 28730275 DOI: 10.1007/s00464-017-5729-0] [Citation(s) in RCA: 75] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2017] [Accepted: 07/13/2017] [Indexed: 12/16/2022]
Abstract
BACKGROUND Transversus abdominis release (TAR) is a safe, effective strategy to repair complex ventral incisional hernia (VIH); however, open TAR (o-TAR) often necessitates prolonged hospitalization. Robot-assisted TAR (r-TAR) may benefit short-term outcomes and shorten convalescence. This study compares 90-day outcomes of o-TAR and r-TAR for VIH repair. METHODS A single-center, retrospective review of patients who underwent o-TAR or r-TAR for VIH from 2015 to 2016 was conducted. Patient and hernia characteristics, operative data, and 90-day outcomes were compared. The primary outcome was hospital length of stay, and secondary metrics were morbidity, surgical site events, and readmission. RESULTS Overall, 102 patients were identified (76 o-TAR and 26 r-TAR). Patients were comparable regarding age, gender, body mass index, and the presence of co-morbidities. Diabetes was more common in the open group (22.3 vs. 0%, P = 0.01). Most VIH defects were midline (89.5 vs. 83%, P = 0.47) and recurrent (52.6 vs. 58.3%, P = 0.65). Hernia characteristics were similar regarding mean defect size (260 ± 209 vs. 235 ± 107 cm2, P = 0.55), mesh removal, and type/size mesh implanted. Average operative time was longer in the r-TAR cohort (287 ± 121 vs. 365 ± 78 min, P < 0.01) despite most receiving mesh fixation with fibrin sealant alone (18.4 vs. 91.7%, P < 0.01). r-TAR trended toward lower morbidity (39.2 vs. 19.2%, P = 0.09), less severe complications, and similar rates of surgical site events and readmission (6.6 vs. 7.7%, P = 1.00). In addition, r-TAR resulted in a significantly shorter median hospital length of stay compared to o-TAR (6 days, 95% CI 5.9-8.3 vs. 3 days, 95% CI 3.2-4.3). CONCLUSIONS In select patients, the robotic surgical platform facilitates a safe, minimally invasive approach to complex abdominal wall reconstruction, specifically TAR. Robot-assisted TAR for VIH offers the short-term benefits of low morbidity and decreased hospital length of stay compared to open TAR.

Feasibility of robotic inguinal hernia repair, a single-institution experience. Surg Endosc 2015; 30:4042-8. [PMID: 26718359 DOI: 10.1007/s00464-015-4717-5] [Citation(s) in RCA: 42] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2015] [Accepted: 12/01/2015] [Indexed: 10/22/2022]
Abstract
BACKGROUND With the growth of the discipline of laparoscopic surgery, technology has been further developed to facilitate the performance of minimally invasive hernia repair. Most of the published literature regarding robotic inguinal hernia repair has been performed by urologists who have dealt with this entity in a concomitant way during radical prostatectomies. General surgeons, who perform the vast majority of inguinal herniorrhaphies worldwide, have yet to describe the role of robotic inguinal hernia repair. Here, we describe our initial experience and create the foundation for future research questions regarding robotic inguinal hernia repair. METHODS A retrospective chart review was performed in 78 patients who underwent robotic transabdominal preperitoneal TAPP inguinal hernia repair with a prosthetic mesh using the da Vinci platform (Intuitive Surgical Inc). Data collected included patient demographics, past medical history, previous surgeries, details related to the surgical procedure, perioperative outcomes and complications. RESULTS A total of 123 hernias were repaired. Forty-five patients had bilateral robotic inguinal herniorrhaphies, and the mean age was 55.1 years (SD 15.1), with a mean BMI of 27.6 (SD 6.1). There were 71 male and 7 female patients. Surgical complications included hematoma in three patients (3.9 %), two seromas (2.6 %) and one superficial surgical site infection at a trocar site (1.3 %), which resolved with oral antibiotics. Chronic postoperative complications (>30 days post-surgery) included the persistence of hematomas in two patients (2.6 %). Same day discharge was achieved in 60 patients (76.9 %) with a mean length of stay of 8 h (SD 2.65). Neither mortality nor conversion to open surgery occurred. CONCLUSION Our early experience has demonstrated that the robotic transabdominal preperitoneal (TAPP) inguinal hernia repair is a safe and versatile approach that allows the general surgeon to perform this procedure in more complex cases such as those involving incarcerated and/or recurrent hernias.
