Background: Smoking and obesity are well-known risk factors for surgical site infection, but it is unknown whether these factors influence outcomes after repair of small umbilical and epigastric hernias with defects ≤2 cm. The aim of this study was to evaluate whether smoking and obesity are associated with readmission, reoperation for complications, and recurrence rates after elective repair of small umbilical and epigastric hernias., Methods: Data on hernia type, size, repair method, smoking status, and body mass index after elective repair were available from the Danish Hernia Database from January 2017 through December 2018. Data on 90-day readmission and reoperation were available from the Danish National Patients Registry., Results: A total of 1,965 patients were included for final analysis, of whom 85.1% (1,672 of 1,965) were repaired by open approach and 70.8% (1,391 of 1,965) with mesh reinforcement. A 100% follow-up was secured, and median follow-up time was 307 (138-432) days. Readmission was significantly higher in smokers (9.6% [34 of 353]) compared with nonsmokers (6.4% [103 of 1,612]), P = .030. The reoperation rate for complications was also significantly higher for smokers (4.0% [14 of 353])) compared with nonsmokers (2.0% [32 of 1,612]) (P = .026). Patients with a body mass index ≥35 kg/m 2 were more frequently readmitted (11.7%; 12 of 102) compared with 6.7% (125 of 1,965) of patients with body mass index ≤34.9 kg/m 2 (P = .046). In multivariate analyses adjusted for age, sex, presence of chronic obstructive pulmonary disease, diabetes, and cardiovascular disease, smoking (odds ratio = 1.52 [1.02-2.30]) and body mass index >40 kg/m 2 (odds ratio = 6.07 [2.03-18.10]) were independent risk factors for readmission., Conclusion: Smoking and obesity have a significantly negative impact on outcomes even after elective repair of small umbilical and epigastric hernias., (Copyright © 2020 Elsevier Inc.

Purpose: Different techniques and mesh materials are used in parastomal hernia repair with recently reported recurrence rates ranging from 10 to 28%. The aim of this cohort study was to examine the risk of recurrence and chronic pain after Sugarbaker or keyhole parastomal hernia repair with intraperitoneal placement of a polyester monofilament macroporous composite mesh., Methods: Data on all patients undergoing parastomal hernia repair with Parietex™ Composite Parastomal Mesh at our institution during a 4-year period were examined. Patients with urostomy were excluded. A team of three experienced surgeons performed all repairs. Follow-up including physical examination was done after 10 days, 6 and 12 months, and hereafter as annual structured telephone interviews. Patients suspected of hernia recurrence were offered computed tomography scan. Chronic pain was defined as pain requiring out-patient visit(s) and/or regular use of analgesics., Results: 79 patients (Sugarbaker, n = 69; keyhole, n = 10) were included. Of those, 72 procedures were performed laparoscopically and seven by open technique. Two patients were reoperated within 30 days with removal of the mesh. In total, seven (9%) patients had parastomal hernia recurrence (reoperation, n = 3; conservative management, n = 4) during follow-up of median 12 months (range 0-49 months). In univariable logistic analyses, type of stoma was associated with recurrence (ileostomy 28% vs colostomy 3%, p = 0.007). Three patients (4%) reported chronic pain., Conclusion: In this study, we found low rates of recurrence and chronic pain following parastomal hernia repair using intraperitoneal reinforcement with a polyester monofilament composite mesh.
