A comparison of outcomes between class-II and class-III obese patients undergoing robotic ventral hernia repair: a multicenter study

Kudsi, O Y; Gokcal, F; Bou-Ayash, N; Watters, E; Pereira, X; Lima, D L; Malcher, F
BACKGROUND:) obese patients after robotic VHR (RVHR). METHODS:) systems. RESULTS:were included in the study. PSM analysis stratified these into 69 patients for each of the class-II and class-III groups. When comparing matched groups, there were no differences in any of the variables across all timeframes, except for a higher rate of Polytetrafluoroethylene (PTFE)-based mesh use in the class-III group (39.1% vs 17.4%, p = 0.008). The estimated recurrence-free time was 76.4 months (95% CI = 72.5-80.4) for the class-II group and 80.4 months (95% CI = 78-82.8) for the class-III group. CONCLUSION/CONCLUSIONS:This multicenter study showed no difference in outcomes after RVHR between matched class-II and class-III obese patients.

Updated guideline for closure of abdominal wall incisions from the European and American Hernia Societies

Deerenberg, Eva B; Henriksen, Nadia A; Antoniou, George A; Antoniou, Stavros A; Bramer, Wichor M; Fischer, John P; Fortelny, Rene H; Gök, Hakan; Harris, Hobart W; Hope, William; Horne, Charlotte M; Jensen, Thomas K; Köckerling, Ferdinand; Kretschmer, Alexander; López-Cano, Manuel; Malcher, Flavio; Shao, Jenny M; Slieker, Juliette C; de Smet, Gijs H J; Stabilini, Cesare; Torkington, Jared; Muysoms, Filip E
BACKGROUND:Incisional hernia is a frequent complication of abdominal wall incision. Surgical technique is an important risk factor for the development of incisional hernia. The aim of these updated guidelines was to provide recommendations to decrease the incidence of incisional hernia. METHODS:A systematic literature search of MEDLINE, Embase, and Cochrane CENTRAL was performed on 22 January 2022. The Scottish Intercollegiate Guidelines Network instrument was used to evaluate systematic reviews and meta-analyses, RCTs, and cohort studies. The GRADE approach (Grading of Recommendations, Assessment, Development and Evaluation) was used to appraise the certainty of the evidence. The guidelines group consisted of surgical specialists, a biomedical information specialist, certified guideline methodologist, and patient representative. RESULTS:Thirty-nine papers were included covering seven key questions, and weak recommendations were made for all of these. Laparoscopic surgery and non-midline incisions are suggested to be preferred when safe and feasible. In laparoscopic surgery, suturing the fascial defect of trocar sites of 10 mm and larger is advised, especially after single-incision laparoscopic surgery and at the umbilicus. For closure of an elective midline laparotomy, a continuous small-bites suturing technique with a slowly absorbable suture is suggested. Prophylactic mesh augmentation after elective midline laparotomy can be considered to reduce the risk of incisional hernia; a permanent synthetic mesh in either the onlay or retromuscular position is advised. CONCLUSION/CONCLUSIONS:These updated guidelines may help surgeons in selecting the optimal approach and location of abdominal wall incisions.

Lateral hernia secondary to colorectal submucosal resection repaired by robotic-assisted approach: Case report

Pacheco, Tulio Brasileiro Silva; Lima, Diego L; Halpern, Robert A; Malcher, Flavio; Halpern, David K
INTRODUCTION AND IMPORTANCE/UNASSIGNED:Lateral abdominal wall defects are a rare event and commonly result from iatrogenic causes and trauma. We report the first known case of flank hernia after endoscopic submucosal resection of a colonic polyp complicated by colonic perforation. CASE PRESENTATION/METHODS:This is a case of a 50-year-old male who underwent endoscopic colonic resection complicated by perforation of the colon. Eight months later, he presented with an enlarging, asymptomatic left flank bulge. CT showed a large flank hernia which was successfully repaired using a robotic transabdominal preperitoneal (TAP) approach. CLINICAL DISCUSSION/UNASSIGNED:The hypothesis is that the endoscopic resection with colonic perforation caused an iatrogenic injury to the abdominal wall creating a lateral abdominal hernia. Injury to abdominal wall musculature may take months to develop into a clinically apparent hernia. Flank hernias can be successfully repaired using a robotic minimally invasive approach. CONCLUSION/CONCLUSIONS:Flank bulge and hernias must be included or at least be considered as consequence of a potential complication from endoscopic colonic perforation. Surgeons and endoscopists must be aware of this potential complication and its latent presentation. This case stresses the importance of long-term outcomes monitoring, particularly with innovative procedures.

Hernia Defect Closure With Barbed Suture: An Assessment of Patient-reported Outcomes in Extraperitoneal Robotic Ventral Hernia Repair

Tagerman, Daniel; Pereira, Xavier; Lima, Diego; Romero-Velez, Gustavo; Friedman, Patricia; Sreeramoju, Prashanth; Malcher, Flavio
BACKGROUND:Primary closure of a fascial defect during ventral hernia repair is associated with lower rates of recurrence and better patient satisfaction compared with bridging repairs. Robotic surgery offers enhanced ability to close these defects and this has likely been aided by the use of barbed suture. The goal of this study was to evaluate the perioperative safety and the long-term outcomes for the use of barbed suture for the primary closure of hernia defects during robotic ventral hernia repair (rVHR) with mesh. METHODS:This is a retrospective study of adult patients who underwent rVHR with the use of a barbed suture for fascial defect closure from August 2018 to August 2020 in an academic center. All the patients included were queried by phone to complete a quality of life assessment to assess patient-reported outcomes (PROs). Subjective sense of a bulge and pain at the previous hernia site has been shown to correlate with hernia recurrence. These questions were used in conjunction with a Hernia-related Quality of Life Survey (HerQles) score to assess a patient's quality of life. RESULTS:A total of 81 patients with 102 hernias were analyzed. Sixty patients (74%) were successfully reached and completed the PRO form at median postoperative day 356 (range: 43 to 818). Eight patients (13% of patients with PRO data) claimed to have both a bulge and pain at their previous hernia site, concerning for possible recurrence. Median overall HerQLes score was 82 [Interquartile Range (IQR): 54 to 99]. Patients with a single hernia defect, when compared with those with multiple defects, had a lower rate of both a bulge (15% vs. 30%) and symptoms (33% vs. 48%), as well as a higher median HerQLes score (85 vs. 62) at the time of PRO follow-up. Patients with previous hernia repair had a lower median HerQLes score of 65 (IQR: 43 to 90) versus 88 (IQR: 62-100). These patients also had a higher rate of sensing a bulge (29% vs. 18%), whereas a sense of symptoms at the site was less (33% vs. 44%). CONCLUSIONS:Barbed suture for fascial defect closure in rVHR was found to be safe with an acceptable rate of possible recurrence by the use of PRO data. Patients with multiple hernias and previous repairs had a higher likelihood of recurrence and a lower quality of life after rVHR.

Robotic mesh explantation (RoME): a novel approach for patients with chronic pain following hernia repair

Mandujano, Cosman Camilo; Tchokouani, Loic; Lima, Diego L; Malcher, Flavio; Jacob, Brian
BACKGROUND:Post-herniorrhaphy pain is common with an estimated 8-10% incidence of mesh-related complications, requiring mesh explantation in up to 6% of cases, most commonly after inguinal hernia repairs. Reoperation for mesh explantation poses a surgical challenge due to adhesions, scarring and mesh incorporation to the surrounding tissues. Robotic technology provides a versatile platform for enhanced exposure to tackle these complex cases. We aim to share our experience with a novel robotic approach to address these complex cases. METHODS:A descriptive, retrospective analysis of patients undergoing a robotic mesh explantation (RoME) for mesh-related chronic pain, or recurrent ventral hernia by two surgeons between the period of March 2016 and January of 2020. The patients were evaluated for resolution of mesh related abdominal pain as well as early post-operative complications. RoME was performed with concomitant hernia repair in cases of recurrences. RESULTS:Twenty-nine patients underwent a robotic mesh explantation (RoME) for mesh-related chronic pain, or recurrent ventral hernia between March 2016 and January of 2020. Nineteen patients (65.5%) had a prior inguinal hernia repair and 10 patients (34.5%) had a prior ventral hernia repair. Indications for mesh removal included chronic pain with or without hernia recurrence. Seventeen patients (58.6%) reported improvement or resolution of pain postoperatively (63% with a prior inguinal hernia repair and 50% of patients with a prior ventral hernia repair). Five patients (17.2%) required mesh reinforcement after explantation. Nineteen patients (65.5%) underwent mesh explantation with primary fascial closure or no mesh reinforcement. The mean follow-up was 36.4 days. The most common postoperative complication was seroma formation (6.8%), with one reported recurrence (3.4%). CONCLUSION/CONCLUSIONS:Robotic mesh explantation in challenging cases due to the effect of chronic scarring, adhesions and mesh incorporation to the surrounding tissues is safe and provides an advantageous platform for concomitant hernia repair in these complex cases.

Social media as a tool for surgical education: a qualitative systematic review

Lima, Diego L; Viscarret, Valentina; Velasco, Juan; Lima, Raquel Nogueira C L; Malcher, Flavio
BACKGROUND:Social media use has exploded, attaining a significant influence within medicine. Previous studies have denoted the use of social media in various surgical specialties as a means to exchange professional ideas and improve the conference experience and at the same time, some have assessed its feasibility as a method of education. This systematic review aims to characterize the use of social media as a tool for general surgery education. METHODS:A systematic review of several databases from each database inception was conducted following the PRISMA guidelines. The JBI's critical appraisal tools were used to assess quality of the studies. RESULTS:A total of 861 articles were identified of which 222 were duplicates removed. The titles and abstracts from the remaining 639 abstracts were screened and 589 were excluded. The remaining 51 full articles were analyzed for eligibility, of which 24 met inclusion criteria and were included in the systematic review. These studies covered the general surgery specialty, of which 11 (n = 46%) focused on the laparoscopic surgical approach, 1 (n = 4%) on robotic-assisted surgical procedures, 1 (n = 4%) on both surgical approaches previously mentioned and 11 (n = 46%) on the general surgery specialty regardless of the surgical approach or technique. CONCLUSIONS:Advantages that SM offers should be considered, and content creators and institutions should help collectively to make sure that the content being published is evidence and guideline-based so its use it is taken to the maximum benefit.

Robotic abdominal wall repair: adoption and early outcomes in a large academic medical center

Pereira, Xavier; Lima, Diego L; Friedmann, Patricia; Romero-Velez, Gustavo; Mandujano, Cosman C; Ramos-Santillan, Vicente; Garcia-Cabrera, Ana; Malcher, Flavio
Robotic-assisted abdominal wall repair (RAWR) has seen an exponential adoption over the last 5 years. Skepticism surrounding the safety, efficacy, and cost continues to limit a more widespread adoption of the platform. We describe our initial experience of 312 patients undergoing RAWR at a large academic center. A retrospective review of all patients undergoing any RAWR from July 1, 2016 to March 18, 2020 was completed. Patient specific, operation specific, and 30-day outcomes specific data were collected. Univariate analysis and multivariate logistic regression were used to assess factors associated with 30-day complications. There was a steady adoption of RAWR over the study period. A total of 312 patient were included, 138 (44%) were abdominal wall repairs and 174 (56%) were inguinal repairs. The mean age of the cohort was 54.2 years (SD 16), 69% were males, and the mean BMI was 29 kg/m2 (SD 4.8). There were two reported intraoperative events and nine operative conversions. 60 patients had at least one complication at 30-days. These include: 52 seromas, 4 hematomas, 2 surgical-site infections, 1 deep venous thrombus, and 1 recurrence at 30-days. BMI, type of hernia, and sex were not associated with complications at 30-days. The use of absorbable mesh, longer hospital stay, operative conversion, previous repair, and expert hernia surgeon were significant predictors of 30-day complications. Age, operative conversion, and previous repair were the only predictors of 30-day complications on multivariate regression. Our initial experience of 312 patients demonstrates the adoption and comparable short-term outcomes for a wide variety of robotic-assisted hernia repairs.
