Comparison of short-term outcomes following robotic ventral hernia repair in patients with obesity: a review of 9742 patients from the Abdominal Core Health Quality Collaborative database. J Robot Surg 2024; 18:265. [PMID: 38916797 DOI: 10.1007/s11701-024-02021-6] [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: 05/24/2024] [Accepted: 06/16/2024] [Indexed: 06/26/2024]
Abstract
Despite the paucity of evidence on robotic ventral hernia repair (RVHR) in patients with obesity, the robotic platform is being used more frequently in hernia surgery. The impact of obesity on RVHR outcomes has not been thoroughly studied. Obesity is considered a major risk factor for the development of recurrent ventral hernias and postoperative complications; however, we hypothesize that patients undergoing robotic repairs will have similar complication profiles despite their body mass index (BMI). We performed a retrospective analysis of patients aged 18-90 years who underwent RVHR between 2013 and 2023 using data from the Abdominal Core Health Quality Collaborative registry. Preoperative, intraoperative, and postoperative characteristics were compared in non-obese and obese groups, determined using a univariate and logistic regression analysis to compare short-term outcomes. The registry identified 9742 patients; 3666 were non-obese; 6076 were classified as obese (BMI > 30 kg/m2). There was an increased odds of surgical site occurrence in patients with obesity, mostly seroma formation; however, obesity was not a significant factor for a complication requiring a procedural intervention after RVHR. In contrast, the hernia-specific quality-of-life scores significantly improved following surgery for all patients, with those with obesity having more substantial improvement from baseline. Obesity does increase the risk of certain complications following RVHR in a BMI-dependent fashion; however, the odds of requiring a procedural intervention are not significantly increased by BMI. Patients with obesity have a significant improvement in their quality of life, and RVHR should be carefully considered in this population.

Association of Metabolic Derangement and Postoperative Outcomes in Hernia Repair With Component Separation: A Propensity Score-matched Nationwide Analysis. J Surg Res 2024; 301:136-145. [PMID: 38925100 DOI: 10.1016/j.jss.2024.05.046] [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: 11/29/2023] [Revised: 05/13/2024] [Accepted: 05/18/2024] [Indexed: 06/28/2024]
Abstract
INTRODUCTION Metabolic syndrome (MetS) is characterized by cardiometabolic abnormalities such as hypertension, obesity, diabetes, or dyslipidemia. This study aims to evaluate the association of MetS on the postoperative outcomes of ventral, umbilical, and epigastric hernia repair using component separation. METHODS The American College of Surgeons National Surgical Quality Improvement Program database was used to identify patients who underwent ventral, umbilical, and epigastric hernia repair with component separation between 2015 and 2021. MetS status was defined as patients receiving medical treatment for diabetes mellitus and hypertension, with a body mass index greater than 30 kg/m2. Propensity matching was performed to generate two balanced cohorts with and without MetS. T-tests and Fisher's Exact tests assessed group differences. Logistic regression models evaluated complications between the groups. RESULTS After propensity score matching, 3930 patients were included in the analysis, with 1965 in each group (MetS versus non-MetS). Significant differences were observed in the severity and clinical presentation of hernias between the groups. The MetS cohort had higher rates of incarcerated hernia (39.1% versus 33.2%; P < 0.001), and recurrent ventral hernia (42.7% versus 36.5%; P < 0.001) compared to the non-MetS cohort. The MetS group demonstrated significantly increased rates of renal insufficiency (P = 0.026), unplanned intubation (P = 0.003), cardiac arrest (P = 0.005), and reoperation rates (P = 0.002) than the non-MetS cohort. Logistic regression models demonstrated higher likelihood of postoperative complications in the MetS group, including mild systemic complications (OR 1.25; 95%CI 1.030-1.518; P = 0.024), severe systemic complications (OR 1.63; 95%CI 1.248-2.120; P < 0.001), and reoperation (OR 1.47; 95%CI 1.158-1.866; P = 0.002). There were no significant differences in the rates of 30-d wound complications between groups. CONCLUSIONS The presence of metabolic derangement appears to be associated with adverse postoperative medical outcomes and increased reoperation rates after hernia repair with component separation. These findings highlight the importance of optimizing preoperative comorbidities as surgeons counsel patients with MetS.

Transversus abdominis release with biosynthetic mesh for large ventral hernia repair: a 5-year analysis of clinical outcomes and quality of life. Hernia 2024; 28:789-801. [PMID: 37755523 DOI: 10.1007/s10029-023-02889-7] [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: 05/17/2023] [Accepted: 09/10/2023] [Indexed: 09/28/2023]
Abstract
INTRODUCTION Transversus abdominis release (TAR) may provide an optimal plane for mesh placement for large ventral hernias requiring medial myofascial flap advancement. Long-term outcomes of TAR for large ventral hernia repair (VHR) remains under-studied. This study aims to assess longitudinal clinical outcomes and quality of life (QoL) following large VHR with TAR and resorbable biosynthetic mesh. METHODS Retrospective review of clinical outcomes and prospective QoL was performed for patients undergoing VHR with poly-4-hydroxybutyrate mesh and TAR from 2016 to 2021. Patients with ≤ 24 months of follow-up, defects ≤ 150 cm2, and parastomal hernias were excluded. Cost-related data was collected for each patient's hospital course. QoL was compared using paired Wilcoxon signed-rank tests. RESULTS Twenty-nine patients met inclusion criteria. Median age and BMI were 61 years (53.2-68.1 years) and 31.4 kg/m2 (26.1-35.3 kg/m2). Average hernia defect was 390cm2 ± 152.9 cm2. All patients underwent previous abdominal surgery and were primarily Ventral Hernia Working Group 2 (58.6%). Two hernia recurrences (6.9%) occurred over the median follow-up period of 63.1 months (IQR 43.7-71.3 months), with no cases of mesh infection or explantation. Delayed healing and seroma occurred in 27 and 10.3% of patients, respectively. QoL analysis identified a significant improvement in postoperative QoL (p < 0.005), that continued throughout the 5-year follow-up period, with a 41% overall improvement. Cost analysis identified the hospital revenue generated was approximately equal to the direct costs of patient care. Higher costs were associated with ASA class and length of stay (p < 0.05). CONCLUSION Large VHR with resorbable biosynthetic mesh and TAR can be performed safely, with a low recurrence and complication rate, acceptable hospital costs, and significant improvement in disease-specific QoL at long-term follow-up.

Abstract
Objective To evaluate the role of Vitamin-D and calcium supplementation on preoperative weight reduction in obese women before laparoscopic ventral hernia repair. Methods This double-blind clinical trial was conducted at the affiliated health centers of King Faisal University, Al-Ahsa, Saudi Arabia from January 2021 to December 2021. It included forty-five obese women aged 24-56 years, with body mass index (BMI) of 34.0-48.0kg/m2. They were randomly allocated into two groups; the Group-A (N=22) included obese women who received supplementation of 5000IU cholecalciferol (Vitamin-D3), and 1000mg calcium daily for 12 months, while the Group-B (N=23) received no treatment. Measurement of change in weight and BMI and comparison of their pre-operative weight reduction, laparoscopic operative time, and length of hospital stay was done. Results There were no differences in patients' biographic data between the two groups. During the study, Vitamin-D level in the patients increased and there was a significant positive association with weight loss. In group-A, the mean weight loss was 11.8±3.5 kg. At the end of first year, their BMI decreased from 36.1±1.6kg/m2 at baseline to 29.7±2.6 kg/m2, whereas in-group-B, the mean weight loss was 6.8±3.1 kg and their BMI decreased from 36.9±2.69kg/m2 at baseline to 32.7±0.93kg/m2. The operation time and the length of hospital stay were shorter in group-A (107 vs.128.min) and (3 vs. 5 days) respectively as compared to Group-B. Conclusion Vitamin-D and calcium supplementation contributes to a remarkable weight reduction of preoperative obese female patients, which in turn is associated with significantly better outcome of laparoscopic repair of ventral hernia.

Abstract
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.

Abstract
PURPOSE Obesity is one of the most important risk factors for complications after ventral hernia repair (VHR), and minimally invasive (MIS) techniques are preferred in obese patients as they minimize wound complications. It is common practice to attempt weight loss to achieve a specific body mass index (BMI) goal; however, patients are often unable to reach it and fail to become surgical candidates. Therefore, we aim to perform a meta-analysis of studies comparing outcomes of obese and nonobese patients undergoing laparoscopic or robotic VHR. PATIENTS AND METHODS A literature search of PubMed, Scopus, and Cochrane Library databases was performed to identify studies comparing obese and nonobese patients undergoing MIS VHR. Postoperative outcomes were assessed by means of pooled analysis and meta-analysis. Statistical analysis was performed using RevMan 5.4. Heterogeneity was assessed with I2 statistics. RESULTS A total of 6483 studies were screened and 26 were thoroughly reviewed. Eleven studies and 3199 patients were included in the meta-analysis. BMI >40 kg/m 2 cutoff analysis included 5 studies and 1533 patients; no differences in hernia recurrence [odds ratios (OR): 1.64; 95% CI: 0.57-4.68; P = 0.36; I2 = 47%), seroma, hematoma, and surgical site infection (SSI) rates were noted. BMI >35 kg/m 2 cutoff analysis included 5 studies and 1403 patients; no differences in hernia recurrence (OR: 1.24; 95% CI: 0.71-2.16; P = 0.58; I2 = 0%), seroma, hematoma, and SSI rates were noted. BMI >30 kg/m 2 cutoff analysis included 4 studies and 385 patients; no differences in hernia recurrence (OR: 2.07; 95% CI: 0.5-8.54; P = 0.32; I2 = 0%), seroma, hematoma, and SSI rates were noted. CONCLUSION Patients with high BMI undergoing MIS VHR have similar hernia recurrence, seroma, hematoma, and SSI rates compared with patients with lower BMI. Further prospective studies with long-term follow-up and patient-reported outcomes are required to establish optimal management in obese patients undergoing VHR.

Abstract
BACKGROUND Preoperative optimization cut-offs are frequently utilized to determine eligibility for elective ventral hernia repair. Our objective was to assess the relationship between gender, race, and socioeconomic status and preoperative optimization goals. METHODS We queried our institutional database for adults with ventral hernia diagnoses between 2016 and 2021. Demographics, comorbidities, laboratory, and operative data were collected and analyzed. The following cut-offs were used to determine eligibility for elective repair: body mass index (BMI) < 40 kg/m2, no active smoking, and glycated hemoglobin (HbA1c) < 8%. Socioeconomic status was assessed using the Distressed Communities Index. RESULTS A total of 5638 patients were included [Whites = 4321 (77%), Blacks = 794 (14%), Hispanics = 318 (6%), and other/unknown 205 (4%)]. Median age was 61 years and 50% were male. Most common hernia types were umbilical (36%) and incisional (20%). 10% had BMI > 40 kg/m2, 9% were active smokers and 4% had HbA1c > 8%. 21% of all patients did not meet the preoperative optimization cut-offs at time of diagnosis and those were less likely to undergo hernia repair during the study timeframe compared to those who did (OR 0.50; 95% CI [0.42-0.60]). There was a higher proportion of females (21%) and Blacks (22%) with BMI > 40 kg/m2 compared to males (11%) and other races (11-15%), p = 0.002. As the level of socioeconomic distress increased, there was a corresponding increase in the proportion of patients who did not meet preoperative optimization cut-offs from 16% in prosperous communities to 25% in distressed communities (p < 0.0001). CONCLUSION Nearly 1 of 5 patients with ventral hernias is affected by commonly used arbitrary preoperative optimization cut-offs. These cut-offs disproportionately impact females, Black patients and those with higher socioeconomic distress. These disparities need to be considered when planning preoperative optimization protocols and resource allocation to ensure equitable access to elective ventral hernia repair.

Abstract
Background Prior work has linked body mass index (BMI) with postoperative outcomes of ventral hernia repair (VHR), though recent data characterizing this association are limited. This study used a contemporary national cohort to investigate the association between BMI and VHR outcomes. Methods Adults ≥ 18 years undergoing isolated, elective, primary VHR were identified using the 2016-2020 American College of Surgeons National Surgical Quality Improvement Program database. Patients were stratified by BMI. Restricted cubic splines were utilized to ascertain the BMI threshold for significantly increased morbidity. Multivariable models were developed to evaluate the association of BMI with outcomes of interest. Results Of ~89,924 patients, 0.5 % were considered Underweight, 12.9 % Normal Weight, 29.5 % Overweight, 29.1 % Class I, 16.6 % Class II, 9.7 % Class III, and 1.7 % Superobese. After risk adjustment, class I (Adjusted Odds Ratio [AOR] 1.22, 95 % Confidence Interval [95%CI]: 1.06-1.41), class II (AOR 1.42, 95%CI: 1.21-1.66), class III obesity (AOR 1.76, 95%CI: 1.49-2.09) and superobesity (AOR 2.25, 95 % CI: 1.71-2.95) remained associated with increased odds of overall morbidity relative to normal BMI following open, but not laparoscopic, VHR. A BMI of 32 was identified as the threshold for the most significant increase in predicted rate of morbidity. Increasing BMI was linked to a stepwise rise in operative time and postoperative length of stay. Conclusion BMI ≥ 32 is associated with greater morbidity following open, but not laparoscopic VHR. The relevance of BMI may be more pronounced in open VHR and must be considered for stratifying risk, improving outcomes, and optimizing care. Key message Body mass index (BMI) continues to be a relevant factor in morbidity and resource use for elective open ventral hernia repair (VHR). A BMI of 32 serves as the threshold for significant increase in overall complications following open VHR, though this association is not observed in operations performed laparoscopically.

Abstract
INTRODUCTION While previous studies have documented adverse outcomes among obese patients undergoing ventral and inguinal hernia repairs, there is a lack of literature regarding the impact of obesity on parastomal hernia (PSH) repair. This retrospective study aims to determine the value of obesity stratification in predicting postoperative complications in patients undergoing PSH repair. MATERIALS AND METHODS Outcomes of elective PSH repairs from 2010 to 2020 in the American College of Surgeons National Surgical Quality Improvement Program database were analyzed. Patient demographics, preoperative characteristics, and postoperative outcomes were compared using bivariate analysis and multivariable regression models. RESULTS A total of 2972 patients were retrospectively analyzed. Multivariable regression found, compared to nonobese patients, patients of obesity class ≥ II were 1.37 times more likely to develop complications overall (P = 0.006) and 1.55 times more likely to develop wound complications (P < 0.001). This group also yielded a 1.60 times higher risk of developing superficial wound infection (P = 0.007) and a 1.63 times greater risk of developing postoperative sepsis (P = 0.044). Total length of stay was longer for patients of obesity class ≥ II but not for obesity class I when compared to patients with body mass index <30.0 kg/m2. CONCLUSIONS Patients with a body mass index ≥35.0 kg/m2 are more susceptible to an increased rate of complications after PSH repairs. The findings of this study will allow surgeons to stratify obese patients who would benefit from preoperative weight loss interventions prior to PSH repair and discuss associated risks with patients to facilitate informed consent.
