BackgroundThe aim of this study was to identify risk factors for an adverse event, i.e. early surgical complication, need for ICU care and readmission, following ventral hernia repair. Our hypothesis was that there is an association between an increased complication rate following ventral hernia repair and specific factors, including hernia size, BMI > 35, concomitant bowel surgery, ASA-class, age, gender and method of hernia repair.MethodsData from a hernia database with prospectively entered data on 408 patients operated for ventral hernia between 2007 and 2014 at two Swedish university hospitals were analysed. A 3-month follow-up of complications, need for intensive care and readmission, was performed by reviewing the medical records.ResultsEighty-one of 408 patients (20%) had a registered complication. Fifty-eight (14%) of these were classed as Clavien I–IIIa, and in 19 cases a Clavien IIIb–IV complication was reported. Large hernia size was associated with increased risk for early complication. A Kendall Tau test analysis revealed a proportional relationship between hernia size and modified Clavien outcome class (p < 0.001). Morbid obesity, ASA-class, method, hernia recurrence, age and concomitant bowel surgery were not statistically significant predictors of adverse events.ConclusionsAssessment of hernia aperture size is of great importance in the preoperative evaluation of ventral hernia patients to consider risk for post-operative complications. These results suggest a careful attitude when applying watchful waiting concepts and when postponing hernia surgery to achieve weight loss. A delaying attitude may result in increased risk of complications caused by increasing hernia size.

Inadvertent enterotomy is overrepresented, and the probability that a claim filed for an avoidable injury leads to high reimbursement is greater if laparoscopic repair is performed rather than open ventral hernia repair. The high amount of injuries related to general anesthesia during umbilical hernia repair may be reduced with an increased proportion executed in local anesthesia.

Background and aims Ventral hernia repair is one of the most common surgical procedures performed worldwide. Despite the large volume, consensus is lacking regarding indications for repair or choice of surgical method used for reconstruction. The aim of this study was to explore the risk for major complications and mortality in ventral hernia repair using data from a nationwide patient register. Method Patient data of individuals over 18 years of age who had a ventral hernia procedure between 2004 and 2014 were retrieved from the Patient Register kept by the Swedish National Board of Health and Welfare. After exclusion of patients with concomitant bowel surgery, 45 676 primary surgical admissions were included. Procedures were dichotomised into laparoscopic and open surgery, and stratified for primary and incisional hernias. Results A total of 45 676 admissions were analysed. The material comprised 36% (16 670) incisional hernias and 64% (29 006) primary hernias. Women had a higher risk for reoperation during index admission after primary hernia repair (OR 1.84 (1.29–2.62)). Forty-three patients died of complications within 30 days of index surgery. Patients aged 80 years and older had a 2.5 times higher risk for a complication leading to reoperation, and a 12-fold higher mortality risk than patients aged 70–79 years. Conclusion Age is the dominant mortality risk factor in ventral hernia repair. Laparoscopic surgery was associated with a lower risk for reoperation during index admission. Reoperation seems to be a valid outcome variable, while registration of complications is generally poor in this type of cohort.

Background Parastomal hernia and stoma-site hernia are common stoma complications. Parastomal hernia repair is associated with high complication and recurrence rates. Insurance data can provide novel information on the consequences of perioperative complications from the patient’s point of view. The aim was to investigate what types of complications associated with stoma-related hernia surgery that cause patients to apply for economic compensation through the patient insurance system and to investigate demographic and clinical differences among cases based on gender and type of center at which the surgery was performed. Methods A national patient damage claim database was searched for ICD-10 codes related to parastomal and stoma-site hernia surgery over a seven-year period. Medical records were screened for claims associated with parastomal hernia repair, relocation or reversal due to parastomal hernia, or stoma-site hernia repair. Claims were classified according to one of four primary complaints: surgical, anesthetic, medical or other. Clinical and demographic differences between genders and hospital types were investigated. Reasons for non-compensation were analyzed. Results Thirty claims met the inclusion criteria. Eighteen were related to parastomal hernia repair, seven to stoma-site hernia repair, three to stoma reversal and two to relocation due to parastomal hernia. Twenty-five claims were primarily surgical, two related to anesthesia and three classified as other. Seven claims were granted compensation. No demographic or clinical differences were found apart from female gender being associated with previous parastomal hernia repair [6 women and 0 men (p = 0.02)]. Conclusion Surgical complaints predominated. Few claims were compensated, reflecting the complexity and unsatisfactory outcomes of these procedures. Many claims were identified in relation to the incidence of stoma-related hernia surgery. Trial registration Due to its retrospective and descriptive nature, the study was not registered in any registry.

Aim One remaining question in ventral hernia repair is whether to perform concurrent abdominal surgery or plan two-stage procedures. The aim was to explore the risk for reoperation and mortality due to surgical complication during index admission. Method Eleven-year data were retrieved from the National Patient Register and 68,058 primary surgical admissions were included, divided into minor and major hernia surgery and concurrent abdominal surgery. Results were evaluated by logistic regression analysis. Results The risk for reoperation during index admission was higher for patients with concurrent surgery. Major hernia surgery and major concurrent surgery had an OR 37.9 compared to major hernia surgery only. Mortality rate within 30 days increased, OR 9.32. The combined risk for serious adverse event was accumulative. Conclusion These results stress the importance of critically evaluating needs for and planning of concurrent abdominal surgery during ventral hernia repair. Reoperation rate was a valid and useful outcome variable
