Robotic ventral hernia repair in octogenarians: perioperative and long-term outcomes

Outcomes and quality of life of frail patients following elective ventral hernia repair: Retrospective review of a national hernia collaborative

BACKGROUND

Ventral hernia repair (VHR) is one of the most common general surgery procedures among older adults but is often deferred due to a higher risk of complications. This study compares postoperative quality of life (QOL) and complications between frail and non-frail patients undergoing elective VHR. We hypothesized that frail patients would have higher complication rates and smaller gains in quality of life compared to non-frail patients.

STUDY DESIGN

Patients 65 years of age and older, undergoing elective VHR between 2018 and 2022 were selected from the ACHQC (Abdominal Core Health Quality Collaborative) and grouped based on frailty scores obtained using the Modified Frailty Index (mFI-5). Logistic regression adjusting for hernia characteristics (size, recurrent, parastomal, incisional) were performed for 30-day outcomes including surgical site infections (SSI), surgical site occurrences (SSO), surgical site infections/occurrences requiring procedural intervention (SSOPI), and readmission. Multivariable analyses controlling for patient and procedure characteristics were performed comparing QOL scores (HerQLes scale, 0-100) at baseline, 30 days, 6 months and 1 year postoperatively.

RESULTS

A total of 4888 patients were included, 29.17% non-frail, 47.87% frail, and 22.95% severely frail. On adjusted analysis, severely frail patients had higher odds of SSO (most commonly seroma formation) but no evidence of a difference in SSI, SSOPI, readmission or mortality. Severely frail patients had lower median QOL scores at baseline (48.3/100, IQR 26.1-71.7, p ​= ​0.001) but reported higher QOL scores at both 30-days (68.3/100, IQR 41.7-88.3, p ​= ​0.01) and 6-months (86.7/100, IQR 65.0-93.3, p ​= ​0.005).

CONCLUSION

Severely frail patients reported similar increases in QOL and similar complications to their not frail counterparts. Our results demonstrate that appropriately selected older patients, even those who are severely frail, may benefit from elective VHR in the appropriate clinical circumstance.

Does smoking influence the clinical outcomes of robotic ventral hernia repair? A propensity score matching analysis study

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.

Robotic vs. Open Approach for Older Adults Undergoing Retromuscular Ventral Hernia Repair

OBJECTIVE

To describe 30-day outcomes including post-operative complications, readmissions, and quality of life score changes for older adults undergoing elective ventral hernia repair with retromuscular mesh placement and to compare rates of these outcomes for individuals undergoing robotic versus open approaches.

SUMMARY OF BACKGROUND DATA

Over one third of patients presenting for elective ventral hernia repair are over the age of 65 and many have complex surgical histories that warrant intricate hernia repairs. Robotic ventral hernia repairs have gained increasing popularity in the US and in some studies have demonstrated decreased rates of postoperative complications, and less pain resulting in shorter hospital stays. However, the robotic approach has several downsides including prolonged operative times as well as the use of pneumo-peritoneum which may be risky in older patients.

METHODS

We performed a retrospective review of prospectively collected data in a national hernia specific registry (the Abdominal Core Health Quality Collaborative) and identified patients over the age of 65 undergoing either an open or robotic retromuscular ventral hernia repair. After propensity score matching adjusting for demographic, clinical, and hernia related factors, logistic regression was used to compare 30-day complications, readmission, and quality of life (QoL) scores as captured by the HerQLes scale for patients undergoing each approach.

RESULTS

Of 2128 patients who met inclusion criteria, 1695 (79.7%) underwent open ventral hernia repair while 433 (20.3%) underwent robotic repair. After propensity score matching, there were 350 robotic cases and 759 open cases for analysis. Patients undergoing robotic repairs demonstrated significantly shorter length of stays (1 vs 4 days, P < 0.01) and had equivalent odds of both 30-day post-operative complications (odds ratio [OR] 1.15 95% confidence interval 0.92-1.44) and readmission (OR 1.09 95% confidence interval 0.74-1.6) compared to the open approach. QoL scores were similar between groups at 30 days but were slightly better for robotic patients at 1 year (92 vs 84 P < 0.01).

CONCLUSIONS

Robotic ventral hernia repair is an option for appropriately selected older patients undergoing retromuscular ventral hernia repair, demonstrating shorter hospital stays and equivalent rates of complications and readmissions in the post-operative period. However, more data is needed regarding QoL outcomes and long-term function, especially as it relates to recurrence rates, between the two approaches.

Can ventral TAPP achieve favorable outcomes in minimally invasive ventral hernia repair? A systematic review and meta-analysis

PURPOSE

The concept of the transabdominal preperitoneal (TAPP) was transferred from the inguinal hernia repair to be adopted in minimally invasive ventral hernia repair (VHR) and since then it has been gaining popularity. However, there are minimal data supporting the ventral TAPP (vTAPP) technique which may lead to reticence in the adoption of this approach. The aim of this meta-analysis was to evaluate the outcomes of patients who received minimally invasive vTAPP for VHR.

STUDY DESIGN

A systematic search was performed of PubMed, Science Direct, Google Scholar and Cochrane Library until July 2022. We selected studies that compared the vTAPP technique with any of other minimally invasive techniques. A meta-analysis was done for the outcomes of perioperative characteristics and postoperative parameters.

RESULTS

A total of 9 studies (1429 patients) were identified. vTAPP was associated with considerable benefit when compared to IPOM. vTAPP was less painful (MD = - 1.01; 95% CI [- 1.39, - 0.64], p < 0.00001), of reduced average cost (MD = - 457.10; 95% CI [- 457.27, - 456.92], p < 0.00001) and decreased SSI (OR = 0.29; 95% [0.09, 0.96], p = 0.04). On the other hand, the vTAPP approach consumed less operative time (MD: - 31.01, 95% CI [- 33.50, - 28.51]), p < 0.00001) and shorter hospital stay than the e-TEP approach.

CONCLUSION

vTAPP appears to be safe and effective procedure for VHR, superior or similar to other minimally invasive techniques for perioperative characteristics and short-term outcomes.

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

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.

Geriatric assessment and medical preoperative screening (GrAMPS) program for older hernia patients

PURPOSE

The incidence of older adults undergoing inguinal and ventral hernia repairs is increasing. Older adults are disproportionately affected by age-related risk factors, which are often under-recognized and may adversely affect surgical outcomes. These age-related risk factors often termed "geriatric syndromes," include multimorbidity, frailty, cognitive impairment, depression, obesity, functional impairment, polypharmacy, and poor subjective health. The aim of this study was to identify the prevalence of age-related risk factors in older patients undergoing elective hernia repair.

METHODS

Patients aged 60 years or older with a planned elective surgical repair of a ventral or inguinal hernia were prospectively enrolled in a clinic. Subjects completed several validated screening tools for geriatric syndromes.

RESULTS

Seventy patients completed preoperative assessments (mean age: 68.5 years). In total, 24 (34.3%) screened positive for previously unrecognized objective cognitive impairment (Mini-Cog) and 33 (47.1%) for a subjective memory concern. Sixty patients (85.7%) met criteria for polypharmacy. Additionally, 48 (68.6%) screened positive for either pre-frailty (37, 52.9%) or frailty (11, 15.7%), and 66 (94.3%) had multimorbidity. Twenty-five (35.7%) patients self-rated their health as "poor" or "fair," and 18 (25.7%) patients endorsed some functional impairment.

CONCLUSIONS

There is a high prevalence of age-related risk factors in older patients undergoing elective hernia repair. Further, these factors are often unrecognized and underappreciated despite their potential to significantly impact informed consent and shared decision making. Additional study is required to define the impact of these age-related risk factors on surgical outcomes, which will inform preoperative risk assessment and optimization through modifiable risk reduction.

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.

Age-Related Risk Factors in Ventral Hernia Repairs: A Review and Call to Action

BACKGROUND

As the population ages, the incidence of ventral hernias in older adults is increasing. Ventral hernia repairs (VHR) should not be considered low risk operations, particularly in older adults who are disproportionately affected by multiple age-related factors that can complicate surgery and adversely affect outcomes. Although age-related risk factors have been well established in other surgical fields, there is currently little data describing their impact on VHR.

METHODS

We performed a systematic review of the literature to identify studies that examine the effects of age-related risk factors on VHR outcomes. This was conducted using Cochrane Library, Embase, PubMed (Medline), and Google Scholar databases, all updated through June 2020. We selected relevant studies using the keywords, multimorbidity, comorbidities, polypharmacy, functional dependence, functional status, frailty, cognitive impairment, dementia, sarcopenia, and malnutrition. Primary outcomes include mortality and overall complications following VHR.

RESULTS

We summarize the evidence basis for the significance of age-related risk factors in elective surgery and discuss how these factors increase the risk of adverse outcomes following VHR. In particular, we explore the impact of the following risk factors: multimorbidity, polypharmacy, functional dependence, frailty, cognitive impairment, sarcopenia, and malnutrition. As opposed to chronological age itself, age-related risk factors are more clinically relevant in determining VHR outcomes.

CONCLUSIONS

Given the increasing complexity of VHR, addressing age-related risk factors pre-operatively has the potential to improve surgical outcomes in older adults. Preoperative risk assessment and individualized prehabilitation programs aimed at improving patient-centered outcomes may be particularly useful in this population.

Elective ventral hernia repair provides significant abdominal wall quality of life improvements in older patients

BACKGROUND

An increasing proportion of ventral hernia patients are over age 65. These patients are frequently offered watchful waiting rather than surgical intervention due to their frail state or perioperative risk. However, many in this age group suffer from significant quality of life impacts that are not well understood.

METHODS

We performed a retrospective cohort study using data from the Abdominal Core Health Quality Collaborative (ACHQC), including adults undergoing elective ventral hernia repair from 2013 to 2019. Median differences in Hernia-Related Quality of Life Survey (HerQLes) summary scores at baseline, 30-days, 6-months, and 1 year post operatively were compared in four age categories (18-40, 40-64, 65-75, 76 +) using multivariable regression. Secondary outcomes included major post-operative complications and mortality.

RESULTS

Of 6681 patients meeting inclusion criteria, 13.5% were 18-40, 55.8% were 41-64, 25.2% were 65-75, and 5% were 76 + . Patients in the 65-75 age group and those over 76 had higher mean baseline HerQLes scores (51.7 and 60.8) compared to those in the 18-40 and 41-64 groups (45 and 43.3, p < 0.01). Patients 65-75 had smaller increases in HerQLes scores at 30 days (6.7) compared to patients in the younger age groups (11.7 for 18-40; 8.3 for 41-64) and the oldest age group (8.3, p < 0.01). However, patients in the older age groups had higher overall median 1 year HerQles Scores (66.7 for 65-75; 78.3 for 76 +) compared to patients in the 18-40 and 41-64 age groups (65 and 58.3, p < 0.01). On multivariable analysis, HerQLes scores at 30 days post-surgery were decreased for patients in the 41-64 (-3.14, CE -5.89, -0.04, p = 0.03) and 65-75 (-4.53; CE -7.65, -1.41, p < 0.01) groups compared to the youngest age group, while those over 76 had no effect.

CONCLUSION

Older adults undergoing ventral hernia repair demonstrate equal gains in hernia-related quality of life compared to younger patients and actually report higher quality of life scores at 30 days, 6 months and, 1 year post-surgery.

Propensity score matching analysis of short-term outcomes in robotic ventral hernia repair for patients with a body mass index above and below 35 kg/m2

OBJECTIVE

The purpose of this study was to compare perioperative complications after robotic ventral hernia repair between patients with non-obese, class-I obesity with those with class-II or class-III obesity.

BACKGROUND

Obesity is a growing epidemic and is considered as an independent risk factor for a multitude of perioperative complications. Laparoscopic ventral hernia repair has been shown as a safe and feasible approach in population with elevated body mass index (BMI). This study compared overall perioperative complications and surgical site events (SSEs) after robotic ventral hernia repair (RVHR) between patients with a BMI 35 kg/m² or more and patients with a BMI lower than 35 kg/m².

METHODS

A retrospective cohort analysis was conducted with one-to-one propensity score matching (PSM) method to obtain balanced groups evaluating patients who underwent RVHR between February 2012 and June 2019 in a single institution. Preoperative, intraoperative, and postoperative variables were reviewed. Postoperative complications and morbidity were assessed using the Clavien-Dindo classification and comprehensive complication index (CCI^®) score system. SSEs were compared.

RESULTS

Our unmatched sample included 526 patients with an average BMI of 31.2 kg/m². Of these, 29.8% (n = 160) patients were in high-BMI group (range 35-59.2). After PSM, 142 patients were assigned to each group. Both groups experienced similar complication rates during 90 days. Clavien-Dindo grades, CCI^® scores, and SSEs did not differ between the two groups.

CONCLUSION

RVHR in class-II and class-III obese patients is safe, feasible, and effective. In addition to this, it has comparable short-term outcomes with those non-obese and class-I obese patients.
