Predictors for recurrence after open umbilical hernia repair in 979 patients

The impact of smoking on ventral and inguinal hernia repair: a systematic review and meta-analysis

PURPOSE

Individual studies indicate poorer outcomes for smokers after hernia repair. Previous meta-analyses have examined the impact of smoking on specific outcomes such as recurrence and surgical site infection, but there has been a lack of comprehensive consensus or systematic review on this subject. Addressing this gap, our study undertakes a systematic review and meta-analysis to assess the impact of smoking on the outcomes of ventral hernia repair (VHR) and inguinal hernia repair.

SOURCE

A thorough search of Cochrane Central, Scopus, SciELO, and PubMed/MEDLINE, focusing on studies that examined the effect of smoking on inguinal and VHR outcomes was conducted. Key outcomes evaluated included recurrence, reoperation, surgical site occurrences (SSO), surgical site infection (SSI), and seroma.

PRINCIPAL FINDINGS

Out of 3296 screened studies, 42 met the inclusion criteria. These comprised 25 studies (69,295 patients) on VHR and 17 studies (204,337 patients) on inguinal hernia repair. The analysis revealed that smokers had significantly higher rates of recurrence (10.4% vs. 9.1%; RR 1.48; 95% CI [1.15; 1.90]; P < 0.01), SSO (13.6% vs. 12.7%; RR 1.44; 95% CI [1.12; 1.86]; P < 0.01) and SSI (6.6% vs. 4.2%; RR 1.64; 95% CI [1.38; 1.94]; P < 0.01) following VHR. Additionally, smokers undergoing inguinal hernia repair showed higher recurrence (9% vs. 8.7%; RR 1.91; 95% CI [1.21; 3.01]; P < 0.01), SSI (0.6% vs. 0.3%; RR 1.6; 95% CI [1.21; 2.0]; P < 0.001), and chronic pain (9.9% vs. 10%; RR 1.24; 95% CI [1.06; 1.45]; P < 0.01) rates. No significant differences were observed in seroma (RR 2.63; 95% CI [0.88; 7.91]; P = 0.084) and reoperation rates (RR 1.48; 95% CI [0.77; 2.85]; P = 0.236) for VHR, and in reoperation rates (RR 0.99; 95% CI [0.51; 1.91]; P = 0.978) for inguinal hernias between smokers and non-smokers. Analysis using funnel plots and Egger's test showed the absence of publication bias in the study outcomes.

CONCLUSION

This comprehensive meta-analysis found statistically significant increases in recurrence rates, and immediate postoperative complications, such as SSO and SSI following inguinal and VHR. Also, our subgroup analysis suggests that the MIS approach seems to be protective of adverse outcomes in the smokers group. However, our findings suggest that these findings are not of clinical relevance, so our data do not support the necessity of smoking cessation before hernia surgery. More studies are needed to elucidate the specific consequences of smoking in both inguinal and ventral hernia repair.

Long-term patient-reported outcome measures (PROMs) after primary ventral or small midline incisional hernia repair

BACKGROUND

Ventral hernia repair is a common elective surgical procedure lacking strong evidence for specific operative approaches. This study aimed to evaluate the outcomes of primary suture repair or polypropylene sandwich mesh repair for ventral hernias. The main outcome measures were the rate of hernia recurrence, and evaluation of long-term complications and patient-reported outcomes.

METHODS

This retrospective cohort study evaluated patient perceived recurrence and pain in patients who had undergone a primary ventral hernia (epigastric, supraumbilical, or umbilical) repair or small (≤20 mm) midline incisional hernia repair 10 years after the procedure. Short-term follow-up occurred up to 6 weeks after the initial operation, while long-term follow-up included patients who were reviewed clinically or interviewed via telephone at or beyond 3 years after the procedure.

RESULTS

Most (75/100, 75.0%) patients had an extra-peritoneal sandwich mesh repair. Short-term follow-up showed minimal pain and normal activities for all patients (97/97, 100%). Long-term follow-up (median 12 years [IQR 11-13]) was achieved in 95.9% (93/97) of patients with only a small number reporting a slight bulge (5/93, 5.4%) and intermittent mild discomfort (8/93, 8.6%). Nine patients (9/97, 9.3%) experienced hernia recurrence, diagnosed at a median of 26 months [interquartile range, IQR, 7-58] post-operatively.

CONCLUSIONS

These findings suggest that an open sandwich mesh technique is a safe and effective method for repairing primary ventral hernias and small midline incisional hernias and is associated with favourable long-term patient-reported outcomes.

Predictive value of hematological parameters in cirrhotic patients with open umbilical hernia repair

PURPOSE

Patients with liver cirrhosis sometimes suffer from high recurrence rates and postoperative complications. We previously reported that platelet-related hematological parameters are associated with the outcomes after incisional herniorrhaphy, and aim to evaluate the predictive value of these criteria in cirrhotic patients undergoing open umbilical herniorrhaphy.

METHODS

This is a retrospective study. The data of 95 cirrhotic patients undergoing open umbilical herniorrhaphy were analyzed. Patients were grouped based on the recurrence and defined hematological values. Platelet-multiple-lymphocyte index (PLM), neutrophil-leukocyte ratio, lymphocyte-monocyte ratio, platelet-neutrophil ratio, systemic immune-inflammation index, and aspartate aminotransferase-leukocyte ratio values were calculated based on preoperative blood analyses. The outcomes were obtained from hospital records and follow-up calls to patients.

RESULTS

Using cutoff values acquired by the Youden Index, we found a PLM value < 27.9, and the history of inguinal herniorrhaphy were revealed to be statistically significant in the recurrence based on univariant and multivariant analyses (p < 0.05). We further divided patients into two groups based on the cutoff value of PLM and found that a PLM value < 27.9 was significantly associated with the recurrence of incisional hernias (p = 0.018) and the occurrence of postoperative foreign sensation (p = 0.044), and tended to result in other postoperative complications such as cardiopathy, respiratory infection, hypoproteinemia, and hepatic diseases (p = 0.089).

CONCLUSION

The preoperative hematological values, especially PLM, may indicate the outcomes in cirrhotic patients after open umbilical herniorrhaphy. Accurate identification of risks may alert the intraoperative and postoperative care for patients.

Preoperative Optimization for Abdominal Wall Reconstruction

Patients requiring abdominal wall reconstruction may have medical comorbidities and/or complex defects. Comorbidities such as smoking, diabetes, obesity, cirrhosis, and frailty have been associated with an increased risk of postoperative complications. Prehabilitation strategies are variably associated with improved outcomes. Large hernia defects and loss of domain may present challenges in achieving fascial closure, an important part of restoring abdominal wall function. Prehabilitation of the abdominal wall can be achieved with the use of botulinum toxin A, and preoperative progressive pneumoperitoneum.

Risk of Reoperation for Recurrence After Elective Primary Groin and Ventral Hernia Repair by Supervised Residents

Importance

Surgical training involves letting residents operate under supervision. Since hernia repair is a common procedure worldwide, it is a frequent part of the surgical curriculum.

Objective

To assess the risk of reoperation for recurrence after elective primary groin and ventral hernia repair performed by supervised residents compared with that by specialists.

Design, Setting, and Participants

This nationwide register-based cohort study included data from January 2016 to September 2021. Patients were followed up until reoperation, emigration, death, or the end of the study period. The study used data from the Danish Inguinal and Ventral Hernia Databases linked with data from the Danish Patient Safety Authority's Online Register via surgeons' unique authorization ID. The cohort included patients aged 18 years or older who underwent primary elective hernia repairs performed by supervised residents or specialists for inguinal, femoral, epigastric, or umbilical hernias. Hernia repairs were divided into the following 4 groups: Lichtenstein groin, laparoscopic transabdominal preperitoneal (TAPP) groin, open ventral, and laparoscopic ventral.

Exposures

Hernia repairs performed by supervised residents vs specialists.

Main Outcomes and Measures

Reoperation for recurrence, analyzed separately for all 4 groups.

Results

A total of 868 specialists and residents who performed 31 683 primary groin and 7777 primary ventral hernia repairs were included in this study. The median age of patients who underwent hernia repair was 60 years (IQR, 48-70 years), and 33 424 patients (84.7%) were male. There was no significant difference in the adjusted risk of reoperation after Lichtenstein groin hernia repair (hazard ratio [HR], 1.26; 95% CI, 0.99-1.59), laparoscopic groin hernia repair (HR, 1.01; 95% CI, 0.73-1.40), open ventral hernia repair (HR, 0.89; 95% CI, 0.61-1.29), and laparoscopic ventral hernia repair (HR, 2.96; 95% CI, 0.99-8.84) performed by supervised residents compared with those by specialists. There was, however, a slightly increased unadjusted, cumulative reoperation rate after Lichtenstein repairs performed by supervised residents compared with those by specialists (4.8% vs 4.2%; P = .048).

Conclusions and Relevance

The findings of this study suggest that neither open nor laparoscopic repair of groin and ventral hernias performed by supervised residents appeared to be associated with a higher risk of reoperation for recurrence compared with the operations performed by specialists. This indicates that residents may safely perform elective hernia repair when supervised as part of their training curriculum.

Short-term complications after onlay versus preperitoneal mesh repair of umbilical hernias: a prospective randomized double-blind trial

PURPOSE

To compare the incidence of surgical site occurrences (SSOs) following onlay versus preperitoneal mesh placement in elective open umbilical hernia repairs.

METHODS

This study presents a secondary analysis of a randomized double-blind trial conducted on female patients with primary umbilical hernias admitted to a general hospital, in a residency training program setting. Fifty-six subjects were randomly assigned to either onlay (n=30) or preperitoneal (n=26) mesh repair group. Data on baseline demographics, past medical history, perioperative details, postoperative pain (visual analogue scale (VAS)), wound-related complications, and recurrence were assessed using a standardized protocol.

RESULTS

No statistically significant differences were observed between groups regarding patients' demographics, comorbidities, or defect size. Operative time averaged 67.5 (28-110) min for onlay and 50.5 (31-90) min for preperitoneal repairs, p=.03. The overall rate of SSOs was 21.4% (n=12), mainly in the onlay group (33% vs 7.7%; p=0.02, 95% CI 0.03-0.85) and mostly due to seromas. There were no between-group significant differences in postoperative VAS scores at all timepoints. After a maximum follow-up of 48 months, one recurrence was reported in the onlay group. By logistic regression, the onlay technique was the only independent risk factor for SSOs.

CONCLUSION

The presented data identified a decreased wound morbidity in preperitoneal umbilical hernia repairs, thus contributing to the limited body of evidence regarding mesh place selection in future guidelines. Further cases from this ongoing study and completion of follow-up are expected to also compare both techniques in terms of long-term outcomes.

Hernia recurrence after primary repair of small umbilical hernia defects

BACKGROUND

An evidence-based approach to the repair of umbilical hernias (UH)<1 cm has yet to be defined.

METHODS

A prospectively maintained, institutional hernia database was queried for patients undergoing primary suture repair of UH ≤ 1 cm. The primary outcome was recurrence and secondary outcomes were wound complications.

RESULTS

Of 332 patients included (226-primary, 106-incisional), recurrence was identified in 4 (1.8%) primary versus 8 (7.5%) incisional-UH (p = 0.022), with follow-up of 4.7 ± 4.4 years. There were 10 (3.0%) wound complications: 4 (1.2%) superficial wound infections, 1 (0.3%) superficial wound dehiscence, and 5 (1.5%) seromas. On multivariable analysis of recurrence, incisional-UH had an odds ratio of 4.2 compared to primary. Suture choice, diabetes, BMI, tobacco-use history, and wound complications were not significant.

CONCLUSIONS

With long term follow-up, recurrence after primary suture repair of UH ≤ 1 cm occurred in 1.8% of primary and 7.5% of incisional UH. On multivariable analysis, incisional-UH increased recurrence odds by 4.2 times compared to primary.

Emergency repair and smoking predict recurrence in a large cohort of ventral hernia patients

PURPOSE

Ventral hernias are frequent and hernia repair is regularly performed by general surgeons. Emergency repair is less frequent and can be challenging. Long-term data comparing outcomes of emergency- vs. elective ventral hernia repair are scarce.

METHODS

Consecutive patients undergoing emergency and elective ventral hernia repair at our institution were prospectively entered in our HerniaMed database between August 2013 and February 2020. Patients were contacted after 1 and 5 years to assess long-term complications. Risk factors for emergency repair and hernia recurrence were assessed by univariate and multivariate analysis.

RESULTS

We included 1307 patients. Emergency and elective hernia repair were performed in 11% and 89% of patients with 1-year follow-up rates of 94% and 92%. Female gender, BMI > 40 kg/m², ASA class 3 and 4, large size umbilical herniation (> 4 cm) and epigastric herniation were more frequent in emergency hernia repair. Binary logistic regression analysis identified emergency repair and smoking as predictors of recurrence (Odds ratio: 4.04 and 95% confidence interval: 1.67-14.21, p = 0.004; Odds ratio: 2.94 and 95% confidence interval: 1.33-9.15, p = 0.011). Furthermore, female gender and significant comorbidity (ASA class 3 and 4) were risk factors for emergency repair (Odds ratio: 1.98 and 95% confidence interval: 01.05-3.74, p = 0.034; Odds ratio: 3.54 and 95% confidence interval: 1.79-6.98, p < 0.001).

CONCLUSIONS

Emergency repair and smoking predicted hernia recurrence. Females and highly comorbid patients are at increased risk for emergency repair and should be prioritized for early elective hernia repair.

Umbilical hernia: could it be the 'canary in the coal mine' for a more significant abdominal wall problem?

BACKGROUND

A considerable proportion of incisional hernias presenting to this unit evolve following simple umbilical hernia repair. Our aim was to review our series of complex ventral hernia repairs and identify the frequency of this problem. Our secondary aim was to encourage surgeons to evaluate whether any of the factors that increase the risk of recurrent hernia may be present, prior to undertaking an umbilical hernia repair.

METHODS

Observational retrospective review of a prospectively maintained single-surgeon database of consecutive patients undergoing surgery for recurrent ventral hernia. Patients presenting with recurrence at the site of a previous umbilical hernia repair were identified and their demographic data collected and analysed. A review of the published literature was performed. Patient and surgeon factors contributing to recurrence were identified and discussed.

RESULTS

Of 386 patients undergoing surgery for a recurrent ventral hernial, 102 (26.4%) were initially managed as 'simple' umbilical hernias repaired with a mesh patch or primary suture repair. 71 (69.6%) patients had undergone one or more subsequent hernia repairs prior to referral to our unit with 16 (15.6%) having had three or more repairs prior to referral.

CONCLUSION

Recurrence rates after umbilical hernia repair are likely to be much higher than surgeons and patients appreciate. There are many aspects to consider in the repair of a 'simple' umbilical hernia and we seek promote a discussion amongst surgeons that umbilical hernias be assessed as a major abdominal wall condition and not relegated to minor surgery status.

Umbilical hernia repair and recurrence: need for a clinical trial?

INTRODUCTION

Umbilical hernia repair, despite its perceived simplicity, is associated with recurrence between 2.7 and 27%, in mesh repair and non mesh repair respectively. Many factors are recognized contributors to recurrence however multiple defects in the linea alba, known to occur in up to 30% of patients, appear to have been overlooked by surgeons.

AIMS

This systematic review assessed reporting of second or multiple linea alba defects in patients undergoing umbilical hernia repair to establish if these anatomical variations could contribute to recurrence along with other potential factors.

METHODS

A systematic review of all published English language articles was undertaken using databases PubMed, Embase, Web of Science and Cochrane Library from January 2014 to 2019. The search terms 'Umbilical hernia' AND 'repair' AND 'recurrence' were used across all databases. Analysis was specified in advance to avoid selection bias, was registered with PROSPERO (154173) and adhered to PRISMA statement.

RESULTS

Six hundred and forty-six initial papers were refined to 10 following article review and grading. The presence of multiple linea alba defects as a contributor to recurrence was not reported in the literature. One paper mentioned the exclusion of six participants from their study due multiple defects. In all 11 factors were significantly associated with umbilical hernia recurrence. These included: large defect, primary closure without mesh, high BMI in 5/10 publications; smoking, diabetes mellitus, surgical site Infection (SSI) and concurrent hernia in 3/10. In addition, the type of mesh, advanced age, liver disease and non-closure of the defect were identified in individual papers.

CONCLUSION

This study identified many factors already known to contribute to umbilical hernia recurrence in adults, but the existence of multiple defects in the linea, despite it prevalence, has evaded investigators. Surgeons need to be consider documentation of this potential confounder which may contribute to recurrence.

General Surgery: Management of Postoperative Complications Following Ventral Hernia Repair and Inguinal Hernia Repair

Ventral and inguinal hernia repairs are some of the most commonly performed general surgery operations worldwide. This review focuses on the management of postoperative complications, which include surgical site infection, hernia recurrence, postoperative pain, and mesh-related issues. In each section, we aim to discuss classifications, risk factors, diagnostic modalities, and treatment options for common complications following hernia repair.

Identification of fifty-seven novel loci for abdominal wall hernia development and their biological and clinical implications: results from the UK Biobank

PURPOSE

Familial aggregation is known for both hernia development and recurrence. To date, only one genome-wide association study (GWAS) limited to inguinal hernia has been reported that identified four risk-associated loci. We aim to investigate polygenic architecture of abdominal wall hernia development and recurrence.

METHODS

A GWAS was performed in 367,394 subjects from the UK Biobank to investigate the polygenic architecture of abdominal wall hernia subtypes (inguinal, femoral, umbilical, ventral) and identify specific single nucleotide polymorphisms (SNPs) that are associated with their risk. Expression quantitative trait loci (eQTL) analysis was performed to identify genes whose expression levels are associated with these SNPs. A genetic risk score (GRS) was used to assess the cumulative effect of multiple independent risk-associated SNPs on hernia development and recurrence in independent subjects (n = 82,064).

RESULTS

Heritability (h²) was 0.12, 0.06, 0.16, and 0.07 for inguinal, femoral, umbilical, and ventral hernias, respectively. A high-level of genetic correlation (r_g) was found among these subtypes of hernia. We confirmed the aforementioned four loci and identified 57 novel loci (P < 5 × 10^-8), including 55, 3, 5, and 3 loci for inguinal, femoral, umbilical, and ventral hernias, respectively. Significantly different expression levels between risk/reference alleles of SNPs were found for 145 genes, including TGF-β2 and AIG1 for inguinal hernia risk and CALD1 for umbilical hernia risk. Finally, higher GRS deciles were significantly associated with increased risk for hernia development (P_trend = 3.33 × 10^-38) and recurrent hernia repair surgery (P_trend = 3.64 × 10^-14).

CONCLUSION

These novel results have potential biological and clinical implications for hernia management in high-risk patients.

Management of epigastric, umbilical, spigelian and small incisional hernia as a day case procedure: results of long-term follow-up after open preperitoneal flat mesh technique

PURPOSE

To investigate short and long-term outcome after the open preperitoneal flat mesh technique (OPFMT) for umbilical, epigastric, spigelian, small incisional and "port-site" hernia performed as a day case procedure.

METHODS

We retrospectively analyzed records of patients who underwent OPFMT for umbilical, epigastric, Spigelian, small incisional and "port-site" hernia in ambulatory settings between 2004 and 2020 at Clinical Center of Serbia. Demographic and clinical characteristics, operative data and postoperative complications were compared between the groups. Univariate and multivariate analyses were performed to identify predictive factors for mesh infection and recurrence.

RESULTS

Overall, 476 patients were divided according to the type of hernia. Early postoperative complications were similar in all study groups. Mesh infection, chronic pain and recurrence were different between groups (p = 0.013, p = 0.019 and p = 0.011, respectively). Overall recurrence rate after OPFMT was 2.5%. Hernia defect, hematoma and length of postoperative stay at the Day Surgery Unit were identified as potential predictors of mesh infection (Odds ratio 6.449, 22.143 and 1.546, respectively; p = 0.027, p = 0.011 and p = 0.038, respectively) while mesh infection was the only potential predictor of recurrence in univariate analysis. Hematoma was an independent predictor of recurrence (Odds ratio 27.068; 95% Confidence interval 2.355-311.073; p = 0.008).

CONCLUSION

The OPFMT performed under local anesthesia as a day case procedure is a safe technique associated with favorable long-term outcome. Hematoma is an independent predictor of mesh infection occurrence.

Techniques of Concomitant Abdominoplasty and Umbilical Hernia Repair: A Review

BACKGROUND

Different methods of performing full abdominoplasty and umbilical hernia (UH) repair simultaneously have been proposed.

OBJECTIVES

The aim of this study was to review and compare UH repair outcomes and umbilical stalk survival.

METHODS

A literature research was performed through 28 December 2019. Other hernia repairs and mini-abdominoplasty (without umbilical transposition) were excluded. The primary outcomes analyzed were rates of UH recurrence, mesh infection, and umbilical necrosis.

RESULTS

Six studies were included (5 retrospectives series, 1 case report). Hernia was repaired by an open approach (3 studies, 28 patients) or a laparoscopic approach (3 studies, 67 patients). UH repair consisted of mesh placement in the intraperitoneal or retromuscular/preperitoneal plane, or suture technique in the intraperitoneal plane. No hernia recurrence, mesh infection, or umbilical necrosis was described.

CONCLUSIONS

Both open and laparoscopic approaches to simultaneous abdominoplasty and UH repair seem to be safe based on the rates of umbilical stalk vascularization, hernia recurrence, and mesh infection. However, more well-designed studies are needed to prove this hypothesis.

Surgeon Volume and Risk of Reoperation after Laparoscopic Primary Ventral Hernia Repair: A Nationwide Register-Based Study

BACKGROUND

Repairs of primary ventral hernias are common procedures but are associated with high recurrence rates. Therefore, it is important to investigate risk factors for recurrence to optimize current treatments. The aim of this study was to assess the impact of annual surgeon volume on the risk of reoperation for recurrence after primary ventral hernia repair.

STUDY DESIGN

We conducted a nationwide register-based study with data from the Danish Ventral Hernia Database and the Danish Patient Safety Authority's Online Register linked via surgeons' authorization identification. We included patients 18 years and older, undergoing umbilical or epigastric hernia repair between 2011 and 2020. Annual surgeon volume was categorized into ≤ 9, 10 to 19, 20 to 29, and ≥ 30 cases. Patients were followed until reoperation, death, emigration, or end of the study period.

RESULTS

We included 7,868 patients who underwent laparoscopic (n = 1,529 [19%]), open mesh (n = 4,138 [53%]), or open nonmesh (n = 2,201 [28%]) repair. There was an increased risk of reoperation after laparoscopic umbilical or epigastric hernia repair for surgeons with ≤ 9 (hazard ratio 6.57; p = 0.008), 10 to 19 (hazard ratio 6.58; p = 0.011), and 20 to 29 (hazard ratio 13.59; p = 0.001) compared with ≥ 30 cases/y. There were no differences in risk of reoperation after open mesh and open nonmesh repair in relation to annual surgeon volume.

CONCLUSIONS

There was a significantly higher risk of reoperation after laparoscopic primary ventral hernia repair performed by lower-volume surgeons compared with high-volume surgeons. Additional research investigating how sufficient surgical training and supervision are ensured is indicated to reduce risk of reoperation after primary ventral hernia repair.

Mesh in Elective Hernia Repair: 10-Year Experience with over 6,000 Patients

BACKGROUND

The use of mesh in hernia repair has faced intense scrutiny, leading patients to become fearful of its use, despite its benefits in reducing hernia recurrence. We report a single institutional experience in performing hernia repair with mesh in terms of hernia-specific outcomes, mesh-related complications, and patient-reported quality of life.

STUDY DESIGN

Patients who underwent abdominal wall hernia repair with mesh at a single institution were identified from a prospectively maintained quality database. Demographic, perioperative, and postoperative outcomes data were analyzed. Surgical Outcomes Measurements System (SOMS) and Carolinas Comfort Scale (CCS) surveys were administered pre- and postoperatively at 3 weeks, 6 months, 1, 2, and 5 years.

RESULTS

Between 2010 and 2020, a total of 6,387 patients underwent abdominal hernia repair with mesh. Inguinal hernia repairs made up the majority (65%) of the operations. Rates of mesh infection varied by hernia type, with lower rates after umbilical (0.0%) and inguinal (0.4%) repair, and highest after incisional repair (1.3%). Similarly, mesh explantation rates were low after umbilical and inguinal repair (0.0% and 0.4%, respectively) and highest after incisional repair (3.0%). Scores on all SOMS domains were significantly improved from baseline (all p < 0.05). On CCS, 2.9%, 3.3%, and 4.4% of patients reported severe or disabling symptoms postoperatively at 1, 2, and 5 years, respectively.

CONCLUSIONS

Rates of mesh-related complications vary by hernia type. A majority of patients report excellent long-term quality of life, although a relatively large percentage of patients experience severe or disabling symptoms at long-term follow-up.

Hernia Size and Mesh Placement in Primary Umbilical Hernia Repair

INTRODUCTION

Umbilical hernia repair (UHR) using mesh has been demonstrated to significantly reduce recurrence. However, many surgical centers still perform tissue repair for UH. In the present study, we assessed a cohort of veteran patients undergoing a standard open tissue repair for primary UH to determine at which size recurrence may preclude tissue repair. A systematic review of the literature on hernia size recommendations to guide mesh placement was performed.

METHODS

A single-institution single-surgeon retrospective review of all patients undergoing open tissue repair of primary UH (n = 344) was undertaken at the VA North Texas Health Care System between 2005 and 2019. Guidelines for the preferred reporting items for systematic reviews and meta-analysis were undertaken for systematic review.

RESULTS

A literature review yielded inconsistent guidance for a specific hernia size to proceed with tissue vs. mesh repair. Our institutional review yielded 17 (4.9%) recurrences. Univariable analysis demonstrated recurrence to be associated with hernia size (2.8 vs. 2.3 cm; P = .04). However, on multivariable analysis, hernia size was demonstrated as not an independent predictor of recurrence [OR 1.47 (95% CI; .97-2.21; P = .07)].

CONCLUSION

A review of the literature suggests mesh placement most commonly when the hernia size is > 2.0 cm; however, sources of evidence are heterogeneous in study design, patient population, and hernia types studied. Our institutional review demonstrated that primary UHs < 2.3 cm can successfully be treated via tissue repair. Larger, recurrent, incisional, and primary epigastric hernias may benefit from mesh placement.

Trocar umbilical hernia repair by open suture repair and open suture-mesh repair in an ambulatory setting in comparison to recurrent and primary umbilical hernia repair

Reports on the ambulatory open repair of umbilical trocal hernias are missing. Patients with trocar, primary and recurrent umbilical hernia open suture and open suture–mesh repair with prospective follow-up were retrospectively evaluated. Patients received perioperative antibiotic prophylaxis, preemptive analgesia and modified anesthesia. In total, 171 patients with umbilical hernia (51 years, female 14%; male 86%) were treated with open suture (n = 29; 17%) and suture–mesh (n = 142; 83%) repair. In total, 10% of patients were treated for trocar hernia (late onset), 5% for recurrent hernia and 85% for a primary umbilical hernia. In total, 29% of trocar hernia repairs had minor complications associated with obesity (40%) and comorbidity (80%). Age, suture and suture–mesh repair were not associated with complications. According to guidelines for umbilical hernia repair open flat mesh may be useful in the treatment of trocar hernia.

Is there an advantage to laparoscopy over open repair of primary umbilical hernias in obese patients? An analysis of the Americas Hernia Society Quality Collaborative (AHSQC)

PURPOSE

The most common techniques used to repair umbilical hernias are open and laparoscopic. As the obesity epidemic in the United States is growing, it is essential to understand how this morbidity affects umbilical hernia repairs. This study compares laparoscopic versus open umbilical hernia repairs in obese patients.

METHODS

All patients with body mass index (BMI) ≥ 30 kg/m² who underwent elective, open or laparoscopic repair of a primary umbilical hernia with mesh were identified from the Americas Hernia Society Quality Collaborative (AHSQC). A retrospective review of the prospectively collected data was conducted. Outcomes of interest included surgical site infections (SSI), surgical site occurrences requiring procedural intervention (SSOPI), hernia-related quality-of-life survey (HerQles), and long-term recurrence. A logistic regression model was used to generate propensity scores.

RESULTS

Of 1507 patients who met the inclusion criteria, 322 were laparoscopic, and 1185 were open cases. The laparoscopic group had higher mean BMI (37 ± 6 vs. 35 ± 5 kg/m² , P < 0.001 ) and mean hernia width (3 cm ± 1 vs. 2 cm ± 2, P < 0.001). Using a propensity score model, we controlled for several clinically relevant covariates. Propensity score adjustment showed no differences in the 30-day HerQles score (OR 0.93, 95% CI 0.58-1.49), SSI (OR 1.57, 95% CI 0.52-4.77), SSOPI (OR 2.85, 95% CI 0.84-9.62) or hernia recurrence (hazard ratio 0.86, 95% CI 0.50-1.49).

CONCLUSION

In obese patients with primary umbilical hernias, there is likely no benefit to laparoscopy over open umbilical hernia repair with mesh with regard to wound morbidity. Although, the long-term recurrence also showed no difference between these two approaches, overall follow up was lacking.
