Is weight trajectory a better marker of wound complication risk than BMI in hernia patients with obesity?

BACKGROUND: Complex ventral hernias are frequently repaired via an open transversus abdominis release (TAR). Obesity, particularly a BMI > 40, is a strong predictor of wound morbidity following this procedure. We aimed to determine if preoperative weight loss may still be beneficial in patients with persistently elevated BMIs. METHODS: A retrospective chart review of patients with obesity (BMI ≥ 30) who underwent open TAR at a tertiary academic medical center from January 2018 to December 2021 was completed. Demographics, medical history, operative details, and postoperative data were analyzed. Weight and BMI were recorded at three time points: > 6 months prior to initial surgical consultation, surgical consultation, and day of surgery. RESULTS: In total, 182 patients with obesity underwent an open TAR. Twenty-seven patients (14.8%) underwent surgery with a BMI > 40; they did not have any significant differences in surgical site occurrences (SSO, 48.1% vs 32.9%, p = 0.13) or surgical site infections (SSI, 25.9% vs 23.2%, p = 0.76) compared to those with a BMI ≤ 40. The average timeframe analyzed for preoperative weight loss was 592 days. Patients who had at least a 3% weight loss (n = 49, 26.9%) had decreased rates of SSI compared to those who did not have this weight loss (12.2% vs 27.8%, p = 0.03), despite the groups having similar BMIs at the time of surgery (36.4 vs 36.0, p = 0.50). Patients who only had a 1% weight loss did not see a decrease in SSI rate compared to those who did not (20.6% vs 25.4%, p = 0.45). CONCLUSION: Weight loss may be a better indicator of a patient's risk for wound morbidity following TAR than BMI alone, as weight loss of at least 3% resulted in fewer SSIs despite similar BMIs at time of surgery. Further research into optimal timing and amount of weight loss, as well as effects on long-term outcomes, is needed to confirm these findings.

Operative dictations in surgical trainees: an underutilized educational resource?

INTRODUCTION: Accurate operative notes are imperative to patient care and are used for communication, billing, quality assurance, and medical-legal conflicts. However, operative note quality often varies and many lack critical details. Unfortunately, no standardized training exists in operative dictations for surgical trainees. This pilot study sought to determine resident ability to dictate a comprehensive operative note and to determine a need for a formal operative dictation curriculum. METHODS: Thirty-eight surgical residents between post-graduate years (PGY) one to four participated in a ventral hernia repair simulation. One senior (PGY3/4) resident coached two junior residents (PGY1/2). Residents completed an informal needs assessment regarding operative dictations. Post-simulation, residents completed an operative dictation. Notes were graded using a modified validated rubric. RESULTS: Thirty-five residents completed the needs assessment, and 38 residents submitted an operative note. Eighty-two percent of this group have completed ≤ 25 operative dictations in training and 77% have received minimal feedback on operative dictations. Out of 33 total points, mean overall score was 18.9 ± 5.4 (Junior resident: 17.9 ± 5.4; Senior resident: 20.9 ± 4.8) Total mean scores did not significantly differ between junior and senior residents (p = 0.10). Senior and junior residents scored similarly on the procedural details component (p = 0.29). Senior residents scored higher on relevant patient history and operative note headers (p = 0.04). CONCLUSION: Standard surgical training may not provide enough teaching and feedback to residents on operative note dictations. A formal residency training curriculum may bolster trainee ability to learn the components of an effective operative note.

Laparoscopic versus robotic inguinal hernia repair: 1- and 2-year outcomes from the RIVAL trial.

INTRODUCTION: Robotic inguinal hernia repair is growing in popularity among general surgeons despite little high-quality evidence supporting short- or long-term advantages over traditional laparoscopic inguinal hernia repair. The original RIVAL trial showed increased operative time, cost, and surgeon frustration for the robotic approach without advantages over laparoscopy. Here we report the 1- and 2-year outcomes of the trial. METHODS: This is a multi-center, patient-blinded, randomized clinical study conducted at six sites from 2016 to 2019, comparing laparoscopic versus robotic transabdominal preperitoneal (TAPP) inguinal hernia repair with follow-up at 1 and 2 years. Outcomes include pain (visual analog scale), neuropathic pain (Leeds assessment of neuropathic symptoms and signs pain scale), wound morbidity, composite hernia recurrence (patient-reported and clinical exam), health-related quality of life (36-item short-form health survey), and physical activity (physical activity assessment tool). RESULTS: Early trial participation included 102 patients; 83 (81%) completed 1-year follow-up (45 laparoscopic vs. 38 robotic) and 77 (75%) completed 2-year follow-up (43 laparoscopic vs. 34 robotic). At 1 and 2 years, pain was similar for both groups. No patients in either treatment arm experienced neuropathic pain. Health-related quality of life and physical activity were similar for both groups at 1 and 2 years. No long-term wound morbidity was seen for either repair type. At 2 years, there was no difference in hernia recurrence (1 laparoscopic vs. 1 robotic; P = 1.0). CONCLUSIONS: Laparoscopic and robotic inguinal hernia repairs have similar long-term outcomes when performed by surgeons with experience in minimally invasive inguinal hernia repairs.

Biologic vs Synthetic Mesh for Single-stage Repair of Contaminated Ventral Hernias: A Randomized Clinical Trial.

IMPORTANCE: Biologic mesh is widely used for reinforcing contaminated ventral hernia repairs; however, it is expensive and has been associated with high rates of long-term hernia recurrence. Synthetic mesh is a lower-cost alternative but its efficacy has not been rigorously studied in individuals with contaminated hernias. OBJECTIVE: To determine whether synthetic mesh results in superior reduction in risk of hernia recurrence compared with biologic mesh during the single-stage repair of clean-contaminated and contaminated ventral hernias. DESIGN, SETTING, AND PARTICIPANTS: This multicenter, single-blinded randomized clinical trial was conducted from December 2012 to April 2019 with a follow-up duration of 2 years. The trial was completed at 5 academic medical centers in the US with specialized units for abdominal wall reconstruction. A total of 253 adult patients with clean-contaminated or contaminated ventral hernias were enrolled in this trial. Follow-up was completed in April 2021. INTERVENTIONS: Retromuscular synthetic or biologic mesh at the time of fascial closure. MAIN OUTCOMES AND MEASURES: The primary outcome was the superiority of synthetic mesh vs biologic mesh at reducing risk of hernia recurrence at 2 years based on intent-to-treat analysis. Secondary outcomes included mesh safety, defined as the rate of surgical site occurrence requiring a procedural intervention, and 30-day hospital direct costs and prosthetic costs. RESULTS: A total of 253 patients (median [IQR] age, 64 [55-70] years; 117 [46%] male) were randomized (126 to synthetic mesh and 127 to biologic mesh) and the follow-up rate was 92% at 2 years. Compared with biologic mesh, synthetic mesh significantly reduced the risk of hernia recurrence (hazard ratio, 0.31; 95% CI, 0.23-0.42; P < .001). The overall intent-to-treat hernia recurrence risk at 2 years was 13% (33 of 253 patients). Recurrence risk with biologic mesh was 20.5% (26 of 127 patients) and with synthetic mesh was 5.6% (7 of 126 patients), with an absolute risk reduction of 14.9% with the use of synthetic mesh (95% CI, -23.8% to -6.1%; P = .001). There was no significant difference in overall 2-year risk of surgical site occurrence requiring a procedural intervention between the groups (odds ratio, 1.22; 95% CI, 0.60-2.44; P = .58). Median (IQR) 30-day hospital direct costs were significantly greater in the biologic group vs the synthetic group ($44 936 [$35 877-$52 656] vs $17 289 [$14 643-$22 901], respectively; P < .001). There was also a significant difference in the price of the prosthetic device between the 2 groups (median [IQR] cost biologic, $21 539 [$20 285-$23 332] vs synthetic, $105 [$105-$118]; P < .001). CONCLUSIONS AND RELEVANCE: Synthetic mesh demonstrated superior 2-year hernia recurrence risk compared with biologic mesh in patients undergoing single-stage repair of contaminated ventral hernias, and both meshes demonstrated similar safety profiles. The price of biologic mesh was over 200 times that of synthetic mesh for these outcomes. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02451176.

A prospective, multicenter trial of a long-term bioabsorbable mesh with Sepra technology in cohort of challenging laparoscopic ventral or incisional hernia repairs (ATLAS trial).

BACKGROUND: This prospective, multicenter, single-arm, open-label study evaluated P4HB-ST mesh in laparoscopic ventral or incisional hernia repair (LVIHR) in patients with Class I (clean) wounds at high risk for Surgical Site Occurrence (SSO). METHODS: Primary endpoint was SSO requiring intervention <45 days. Secondary endpoints included: surgical procedure time, length of stay, SSO >45 days, hernia recurrence, device-related adverse events, reoperation, and Quality of Life at 1, 3, 6, 12, 18, and 24-months. RESULTS: 120 patients (52.5% male), mean age of 55.0 ± 14.9 years, and BMI of 33.2 ± 4.5 kg/m2 received P4HB-ST mesh. Patient-reported comorbid conditions included: obesity (86.7%), active smoker (45.0%), COPD (5.0%), diabetes (16.7%), immunosuppression (2.5%), coronary artery disease (7.5%), chronic corticosteroid use (2.5%), hypoalbuminemia (0.8%), advanced age (10.0%), and renal insufficiency (0.8%). Hernia types were primary ventral (44.2%), primary incisional (37.5%), recurrent ventral (5.8%), and recurrent incisional (12.5%). Patients underwent LVIHR in laparoscopic (55.8%) or robotic-assisted cases (44.2%), mean defect size 15.7 ± 28.3 cm2, mean procedure time 85.9 ± 43.0 min, and mean length of stay 1.0 ± 1.4 days. There were no SSOs requiring intervention beyond 45 days, n = 38 (31.7%) recurrences, n = 22 (18.3%) reoperations, and n = 2 (1.7%) device-related adverse events (excluding recurrence). CONCLUSION: P4HB-ST mesh demonstrated low rates of SSO and device-related complications, with improved quality of life scores, and reoperation rate comparable to other published studies. Recurrence rate was higher than expected at 31.7%. However, when analyzed by hernia defect size, recurrence was disproportionately high in defects ≥7.1 cm2 (43.3%) compared to defects <7.1 cm2 (18.6%). Thus, in LVIHR, P4HB-ST may be better suited for small defects. Caution is warranted when utilizing P4HB-ST in laparoscopic IPOM repair of larger defects until additional studies can further investigate outcomes.

Evaluation of information on the Internet regarding surgical mesh for hernia repair: analysis of websites found through three popular search engines.

PURPOSE: Hernia repair remains one of the most common surgical procedures. Surgical mesh usage has been highlighted in the media due to recent lawsuits and recalls. Patients can read potentially biased information on the Internet and this can influence a patient's healthcare decisions. The purpose of this study is to evaluate search engine listings and respective website content of surgical mesh for hernia repair. METHODS: Websites evaluated were derived from four keyword searches targeting surgical mesh with Google, Yahoo, and Bing. Websites from the first two pages of each search were evaluated for content comprehensiveness. RESULTS: The largest category of websites from search engine results was legal advertisements, accounting for 20% of all results. These websites also held the first position on every results page. Legal advertisements and blog/forum websites were the most skewed toward surgical mesh risks and complications vs. benefits. There was a reduction in advertisements in 2020 vs. 2018. The most comprehensive non-advertisement websites were found more frequently. Overall, only 44% of websites presented references and 50% cited supporting data. Finally, 46% of 'recommended search terms' displayed on the search engine results page had a risk, complication, or legal bias. CONCLUSIONS: These results emphasize the challenges of using an Internet search engine to find comprehensive and appropriate information regarding surgical mesh. This manuscript underscores the importance for physicians to direct patients toward specific websites to mitigate their exposure to websites that are biased and not appropriate for patients searching for an accurate and comprehensive overview of surgical mesh.

Examination of abdominal wall perfusion using varying suture techniques for midline abdominal laparotomy closure.

BACKGROUND: With a growing interest in the primary prevention of incisional hernias, it has been hypothesized that different suturing techniques may cause various levels of tissue ischemia. Using ICG laser-induced fluorescence angiography (ICG-FA), we studied the effect of different suture materials and closure techniques on abdominal wall perfusion. METHODS: Fifteen porcine subjects underwent midline laparotomy, bilateral skin flap creation, and three separate 7 cm midline fascial incisions. Animals underwent fascial closure with 5 different techniques: (1) Running 0-PDS® II (polydioxanone) Suture with large bites; (2) Running 0-PDS II Suture with small bites; (3) Interrupted figure-of-eight (8) PDS II Suture, (4) Running 0-barbed STRATAFIX™ Symmetric PDS™ Plus Knotless Tissue Control Device large bite; (5) Running 0-STRATAFIX Symmetric PDS Plus Device small bites. ICG-FA signal intensity was recorded prior to fascial incision (baseline), immediately following fascial closure (closure), and at one-week (1-week.). Post-mortem, the abdominal walls were analyzed for inflammation, neovascularity, and necrosis. RESULTS: PDS II Suture with small bites, fascial closure at the caudal 1/3 of the abdominal wall, and the 1-week time period were all independently associated with increased tissue perfusion. There was also a significant increase in tissue perfusion from closure to 1-week when using small bites PDS II Suture compared to PDS II Suture figure-of-8 (p < 0.001) and a trend towards significance when compared with large bites PDS II Suture (p = 0.056). Additionally, the change in perfusion from baseline to 1 week with small bites was higher than with figure of 8 (p = 0.002). Across all locations, small bite PDS II Suture has greater total inflammation than figure of 8 (p < 0.001). CONCLUSIONS: The results suggest that the small bite technique increases abdominal wall perfusion and ICG-FA technology can reliably map abdominal wall perfusion. This finding may help explain the reduced incisional hernia rates seen in clinical studies with the small bite closure technique.

Chronological age does not predict postoperative outcomes following transversus abdominis release (TAR).

BACKGROUND: Transversus abdominis release (TAR) is an effective procedure for the repair of complex ventral hernias. However, TAR is not a low risk operation, particularly in older adults who are disproportionately affected by multiple age-related risk factors. While past studies have suggested that age alone inconsistently predicts patient outcomes, data regarding age's effect on postoperative outcomes and wound complications following a TAR are lacking. METHODS: Patients who underwent either an open or robotic bilateral TAR from 1/2018 to 9/2020 were eligible for the study. Patients were stratified by age groups (≥ 60 years vs. < 60 years and < 60, 60-70, and ≥ 70) and by both age and operative approach. The rates of key postoperative outcomes and wound morbidity were compared between the various cohorts. RESULTS: A total of 300 patients were included: 165 patients were ≥ 60 and 135 patients were < 60. Cohorts stratified by age were well-matched for important hernia factors: defect size (p = 0.31), BMI ≥ 30 (p = 0.46), OR time (p = 0.25), percent open TAR (p = 0.42), diabetes (p = 0.45) and history of prior surgical site infection (p = 0.40). The older cohort had significantly higher rates of coronary artery disease, hypertension, and COPD. On univariate analysis, cohorts stratified by age had similar rates of key postoperative and wound complications including in-hospital complications (p = 0.62), length of stay (p = 0.47), readmissions (p = 0.66), and surgical site occurrences (p = 0.68). Additionally, cohorts stratified by both age and operative approach also had similar outcomes. Multivariate analysis showed that chronological age was not independently associated with surgical site occurrences (p = 0.22), readmissions (p = 0.99), in-hospital complications (p = 0.15), or severe complications (p = 0.79). CONCLUSION: Open and robotic TARs can be safely performed in older adults and chronological age alone is a poor predictor of patient morbidity following TAR. Further investigation of alternative preoperative screening tools that do not rely solely on age are needed to better optimize surgical outcomes in older adults following TAR.

Does immunosuppression increase perioperative wound morbidity in patients undergoing transversus abdominis release?

BACKGROUND: Transversus abdominis release is an effective procedure for complex ventral hernias. As wound complications contribute to hernia recurrences, mitigating risk factors is vitally important for hernia surgeons. Although immunosuppression can impair wound healing, it has inconsistently predicted wound occurrences, and its effect on wound morbidity after a transversus abdominis release is unknown. METHODS: Patients undergoing either an elective open or robotic bilateral transversus abdominis release with permanent synthetic mesh were retrospectively stratified by perioperative immunosuppression and secondarily by procedure type (open versus robotic) and immunosuppression. RESULTS: A total of 321 patients were included for analysis. Overall, 63 (19.6%) patients were on chronic immunosuppression, with history of solid-organ transplant being the most common indication (43 patients). Patients stratified by perioperative immunosuppression were well-matched with similar defect size (P = .97), body mass index ≥30 (P = .32), diabetes (P = .09), history of surgical site infection (P = .53), surgical approach (P = .53), and tobacco use history (P = .33). No differences between cohorts were elicited for any wound event when stratified by immunosuppression use. Similarly, no differences were elicited when cohorts were further stratified also by procedure type. CONCLUSION: Chronic immunosuppression is often viewed as a notable risk factor for wound occurrences after surgery. However, our data suggest immunosuppression may not significantly increase the risk of perioperative wound morbidity follow transversus abdominis release as previously predicted.

Transversus abdominis release with posterior component separation in patients with previously recurrent ventral hernias: A single institution experience.

BACKGROUND: Recurrent hernias pose significant challenges due to violated anatomic planes, resultant scar, and potential prior mesh. Transversus abdominis release has been widely utilized for complex hernias. Transversus abdominis release can provide a novel plane for dissection and mesh placement for recurrent hernias. This study provides our institution's experience with transversus abdominis release in patients with recurrent ventral hernias. METHODS: A retrospective chart review was conducted of patients with recurrent ventral hernias from January 2018 to September 2020 who underwent transversus abdominis release by 2 fellowship-trained abdominal wall surgeons. Combined procedures (ie, gynecological/urological), robotic totally extraperitoneal, and emergency cases were excluded. Demographics, perioperative, and postoperative outcomes were reviewed. RESULTS: In total, 108 patients underwent open-transversus abdominis release and 25 had robotic-transversus abdominis release for recurrent ventral hernias. All patients received a lightweight to midweight nonabsorbable polypropylene synthetic mesh. Mean age was 59, mean body mass index was 34 kg/m2, with mean hernia defect area of 333 cm2. We noted 34 (25.6%) surgical site occurrences and 11 (8.3%) surgical site infections. Mean postoperative follow-up was 15.5 months, with 7 (5%) recurrences (6 open-transversus abdominis release, 1 robotic-transversus abdominis release). A minimum 12-month follow-up was available for 62% of patients, and minimum 6-month follow-up in 80% of patients. CONCLUSION: Recurrent hernias pose significant operative challenges for surgeons due to violated tissue planes and limited repair options. Our experience suggests that transversus abdominis release may provide a durable repair for difficult recurrent ventral hernias. However, long-term postoperative follow-up over multiple years is still needed to establish extended durability of transversus abdominis release in these patients.

Reducing Operating Room Cost: Comparing Attending and Surgical Trainee Perceptions About the Implementation of Supply Receipts.

BACKGROUND: As operating room (OR) expenditures increase, faculty and surgical trainees will play a key role in curbing future costs. However, supply cost utilization varies widely among providers and, despite requirements for cost education during surgical training, little is known about trainees' comfort discussing these topics. To improve OR cost transparency, our institution began delivering real-time supply "receipts" to faculty and trainees after each surgical case. This study compares faculty and surgical trainees' perceptions about supply receipts and their effect on individual practice and cultural change. STUDY DESIGN: Faculty and surgical trainees (residents and fellows) from all adult surgical specialties at a large academic center were emailed separate surveys. RESULTS: A total of 120 faculty (30.0% response rate) and 119 trainees (35.7% response rate) completed the survey. Compared with trainees, faculty are more confident discussing OR costs (p < 0.001). Two-thirds of trainees report discussing OR costs with faculty as opposed to 77.0% of faculty who acknowledge having these conversations (p = 0.08). Both groups showed a strong commitment to reduce OR expenditures, with 87.3% of faculty and 90.0% of trainees expressing a responsibility to curb OR costs (p = 0.84). After 1 year of implementation, faculty continue to have high interest levels in supply receipts (82.4%) and many surgeons review them after each case (67.7%). In addition, 74.3% of faculty are now aware of how to lower OR costs and 52.5% have changed the OR supplies they use. Trainees, in particular, desire additional cost-reducing efforts at our institution (p < 0.001). CONCLUSIONS: Supply receipts have been well received and have led to meaningful cultural changes. However, trainees are less confident discussing these issues and desire a greater emphasis on OR cost in their curriculum.

Identifying critical computed tomography (CT) imaging findings for the preoperative planning of ventral hernia repairs.

PURPOSE: Computed Tomography (CT) reports vary in qualitative detail and may not capture the information required for the preoperative planning of ventral hernia repairs. The goals of this study were to first survey general and hernia surgeons to establish key hernia imaging characteristics that should be included on CT reports and secondly, to retrospectively review preoperative CTs to determine the percentage that these same imaging characteristics are being reported. METHODS: General and hernia surgeons were surveyed and asked to rank important hernia imaging factors as determined by two academic hernia surgeons on a Likert scoring scale. Additionally, preoperative abdominal/pelvic CT reports of patients who underwent a ventral hernia repair at a single academic institution were retrospectively reviewed for the presence of these imaging factors. RESULTS: Fifty-one general and hernia surgeons responded to the survey. The most important imaging findings as determined by survey respondents were size of the hernia defect and presence of previous mesh. Additionally, 61% of respondents felt that the imaging report was less important than their own personal CT interpretation. Of the 257 preoperative CT reports reviewed, the number of defects was the most commonly reported factor (100%). The size of the defect and the presence of prior mesh was only included on 38% and 15% of reports, respectively. CONCLUSIONS: CT reports vary in their reported imaging findings and often fail to include important preoperative hernia features. Future studies should aim to standardize imaging reports to better utilize CTs for the preoperative planning of abdominal wall reconstructions.

A Practical Guideline for the Implementation of Shared Decision-making in Complex Ventral Incisional Hernia Repair.

BACKGROUND: Although obtaining preoperative procedural consent is required to meet legal and ethical obligations, consent is often relegated to a unidirectional conversation between surgeons and patients. In contrast, shared decision-making (SDM) is a collaborative dialog that elicits patient preferences. Despite emerging interest in SDM, there is a paucity of literature on its application to ventral incisional hernia repair (VIHR). The various surgical techniques and mesh types available, the potential impact on functional outcomes and quality of life, the largely elective nature of the operation, and the significant risk of perioperative patient complications render VIHR an ideal field for SDM implementation. METHODS: The authors reviewed the current literature and drew on their own practice experience to describe evidence-based practical guidelines for implementing the SDM into VIHR care. RESULTS: We summarized the evidence basis for SDM in surgery and discussed how this model can be applied to VIHR given the multiple, complex factors that influence surgical decision-making. We outlined an example of using an SDM framework, "SHARE," with a patient with a large, recurrent ventral hernia. CONCLUSIONS: SDM has the potential to improve patient-centered and preference-concordant care among individuals being considered for VIHR to ensure that treatment interventions meet a patient's goals, rather than solely treating the underlying disease process.

Initial Experience with a Virtual Platform for Advanced Gastrointestinal Minimally Invasive Surgery Fellowship Interviews.

BACKGROUND: The COVID-19 pandemic travel restrictions triggered a rapid alteration in the interview process for fellowships this spring. We describe our initial experience with virtual interviews for Advanced Gastrointestinal (GI) Minimally Invasive Surgery Fellowships and assess the value and limitations via a post-interview applicant survey. STUDY DESIGN: Twenty candidates were interviewed via Zoom teleconferencing during March and April 2020 using combined group and breakout rooms. An anonymous post-interview Likert and free text survey was sent to candidates with questions regarding feasibility, appropriateness, and acceptability of this method. RESULTS: Seventeen of 20 candidates (85%) responded to the survey. The candidates rated ease of interaction with the program director, faculty surgeons, and the current fellow highly: 94%, 83%, and 89%, respectively. The majority (53%) stated the virtual interviews exceeded or met expectations. Only a minority, 12%, reported the virtual platform was short of expectations. Approximately 70% noted little to no impact of not being able to conduct these interviews in-person and not being able to physically see the program institution. Overall, 94% were satisfied with their experience, and only 6% were neutral, with no respondents reporting dissatisfaction. Finally, 76% would recommend a virtual interview in the future. Most negative open response comments were secondary to issues with software rather than the lack of the in-person traditional interviews. CONCLUSIONS: The use of a remote teleconferencing platform provides a favorable method for conducting fellowship interviews and results in a high degree of candidate satisfaction. Virtual interviews will likely be increasingly substituted for in-person interviews across the spectrum of medical training.

Robotic Inguinal vs Transabdominal Laparoscopic Inguinal Hernia Repair: The RIVAL Randomized Clinical Trial.

Importance: Despite rapid adoption of the robotic platform for inguinal hernia repair in the US, to date, no level I trials have ever compared robotic inguinal hernia repair to laparoscopic repair. This multicenter randomized clinical trial is the first to compare the robotic platform to laparoscopic approach for minimally invasive inguinal hernia repair. Objective: To determine whether the robotic approach to inguinal hernia repair results in improved postoperative outcomes compared with traditional laparoscopic inguinal hernia repairs. Design, Setting, and Participants: This multicenter, single-blinded, prospective randomized clinical pilot study was conducted from April 2016 to April 2019, with a follow-up duration of 30 days in 6 academic and academic-affiliated sites. Enrolled in this study were 113 patients with a unilateral primary or recurrent inguinal hernia. After exclusions 102 remained for analysis. Interventions: Standard laparoscopic transabdominal preperitoneal repair or robotic transabdominal preperitoneal repair. Main Outcomes and Measures: Main outcomes included postoperative pain, health-related quality of life, mobility, wound morbidity, and cosmesis. Secondary outcomes included cost, surgeon ergonomics, and surgeon mental workload. A primary outcome was not selected because this study was designed as a pilot study. The hypothesis was formulated prior to data collection. Results: A total of 102 patients were included in the study (54 in the laparoscopic group, mean [SD] age, 57.2 [13.3] years and 48 [88.9%] male; 48 in the robotic group, mean [SD] age, 56.1 [14.1] years and 44 [91.6%] male). There were no differences at the preoperative, 1-week, or 30-day points between the groups in terms of wound events, readmissions, pain as measured by the Visual Analog Scale, or quality of life as measured by the 36-Item Short Form Health Survey. Compared with traditional laparoscopic inguinal hernia repair, robotic transabdominal preperitoneal repair was associated with longer median (interquartile range) operative times (75.5 [59.0-93.8] minutes vs 40.5 [29.2-63.8] minutes, respectively; P < .001), higher median (interquartile range) cost ($3258 [$2568-$4118] vs $1421 [$1196-$1930], respectively; P < .001), and higher mean (SD) frustration levels on the NASA Task Load Index Scale (range, 1-100, with lower scores indicating lower cognitive workload) (32.7 [23.5] vs 20.1 [19.2], respectively; P = .004). There were no differences in ergonomics of the surgeons between the groups as measured by the Rapid Upper Limb Assessment instrument. Conclusions and Relevance: Results of this study showed no clinical benefit to the robotic approach to straightforward inguinal hernia repair compared with the laparoscopic approach. The robotic approach incurred higher costs and more operative time compared with the laparoscopic approach, with added surgeon frustration and no ergonomic benefit to surgeons. Trial Registration: ClinicalTrials.gov Identifier: NCT02816658.

The impact of internet-based patient self-education of surgical mesh on patient attitudes and healthcare decisions prior to hernia surgery.

BACKGROUND: As internet access improves, patient self-education continues to increase. However, patient surgical background, e-literacy, and media exposure potentially influence what information patients search online. This impacts patient concern, healthcare decisions, and subsequent patient-physician interactions. The purpose of this pilot study is to characterize hernia patients' use and the impact of internet self-education regarding surgical mesh. METHODS: The target population included patients presenting for evaluation of hernia repair with mesh. A total of 30 patients were enrolled. Patients took surveys before and after the initial surgical consult. The surveys evaluated internet use, mesh research completed, the impact on patient opinions/decisions, and the impact of research on the patient-physician interaction. RESULTS: The average age of the patients was 58.7 years; sixteen had prior surgery with surgical mesh. 93% of patients were aware of surgical mesh through the media, and 60% were motivated by the media to conduct research. 90% of patients conducted research, and 67% used the internet. Patients with negative attitudes toward mesh had more media exposure in comparison to those with neutral or positive attitudes (p = 0.046), and they were more likely to have researched surgical mesh because of media influence (p = 0.033). This group had the highest rate of perceived knowledge on mesh risks and the lowest regarding benefits (p = 0.013). Patients who had prior surgery without complication had the most positive attitude toward surgical mesh (p = 0.010) and were less likely to plan to do future internet research (p = 0.041) in comparison to patients who had surgery with complications or no prior surgery. CONCLUSIONS: Patients' attitudes and perceived knowledge regarding surgical mesh are associated with media exposure and internet research. These attributes along with prior surgical experience impact the patient-physician relationship and shared decision-making model regarding patient care.

Controversies and Techniques in the Repair of Abdominal Wall Hernias.

Abdominal wall hernia repair is one of the most common operations done by general surgeons today. Patients with incisional hernias can be extremely challenging to manage due to a number of factors that include obesity, prior hernia repairs, previous mesh placement, loss of domain, and other variables. The approach to patients with incisional hernias has evolved considerably over the last 20 years due to both advances in mesh technology and surgical approaches. Key factors in a successful outcome include modification of risk factors prior to surgery such as smoking cessation and weight reduction, selection of mesh appropriate to the hernia type and planned location of the mesh, and broad overlap of mesh beyond the margins of the hernia defect. Newer techniques such as transabdominis release and component separation with retrorectus mesh placement and robotic approaches to abdominal wall hernia are being increasingly utilized in these patients. This article reviews these aspects of abdominal wall hernia repair with a discussion of recent results and the importance of quality improvement and monitoring of outcomes.

Postoperative opioid prescribing practices and the impact of the hydrocodone schedule change.

BACKGROUND: In 2014, hydrocodone was moved from Schedule III to II, thus it could no longer be "called in" to a pharmacy. We analyzed current postoperative opioid prescribing patterns and the impact of the schedule change on the type and amount prescribed. METHODS: Opioid prescriptions for common surgeries at 1 medical center from 2013 to 2016 were analyzed retrospectively. Milligram morphine equivalents prescribed before and after the schedule change were compared by t tests, and interrupted time series models and drug frequencies were compared by χ2 and Fisher exact tests. RESULTS: Data from 7,046 patients (7,361 prescriptions) after 29 different operations were analyzed. Milligram morphine equivalents prescribed for minor open procedures ranged from 211 to 342 milligram morphine equivalents, from 323 to 1297 for major open procedures, from 238 to 359 for basic laparoscopic procedures, and from 221 to 868 for complex laparoscopic procedures. Mean milligram morphine equivalents prescribed were not affected for most procedures, but over the entire population, milligram morphine equivalents prescribed began decreasing after the rule change. The percentage of hydrocodone prescriptions decreased after the rule change (from 33.8% down to 27.0%) and oxycodone and tramadol prescriptions increased. CONCLUSION: Before versus after the rule change, hydrocodone prescriptions decreased and oxycodone and tramadol prescriptions increased. Milligram morphine equivalents prescribed varied considerably across and within classes of procedures, but the schedule change did not affect mean milligram morphine equivalents prescribed for most procedures.

Opioid Medication Use in the Surgical Patient: An Assessment of Prescribing Patterns and Use.

BACKGROUND: With the epidemic of prescription opioid abuse in the US, rates of opioid-related unintentional deaths have risen dramatically. However, few data exist comparing postoperative opioid prescriptions with patient use. We sought to better elucidate this relationship in surgical patients. STUDY DESIGN: A prospective cohort study was conducted of narcotic-naïve patients undergoing open and laparoscopic abdominal procedures on a minimally invasive surgery service. During the first 14 post-discharge days and at their first postoperative clinic visit, patients recorded pain scores and number of opioid pills taken. Clinical data were extracted from the medical record. Descriptive statistics were used in data analysis. RESULTS: From 2014 through 2017, one hundred and seventy-six patients completed postoperative pain surveys. Mean age was 60.4 ± 14.9 years and sex was distributed equally. Most patients (69.9%) underwent laparoscopic procedures. Hydrocodone-acetaminophen was the most commonly prescribed postoperative pain medication (118 patients [67.0%]), followed by oxycodone-acetaminophen (26 patients [14.8%]). Patients were prescribed a median of 150 morphine milligram equivalents (MME) (interquartile range [IQR] 150 to 225 MME), equivalent to twenty 5-mg oral oxycodone pills (IQR 20 to 30 pills). However, by their first postoperative visit, they had only taken a median 30 MME (IQR 10 to 90 MME), or 4 pills (IQR 1.3 to 12 pills). Eight (4.5%) patients received a refill or an additional prescription for pain medications. At the first postoperative visit, 76.7% of respondents were satisfied or very satisfied with their overall postoperative pain management. CONCLUSIONS: Postoperative patients might consume less than half of the opioid pills they are prescribed. More research is needed to standardize opioid prescriptions for postoperative pain management while reducing opioid diversion.
