Long-Term Follow-Up of Retromuscular Incisional Hernia Repairs: Recurrence and Quality of Life.

PURPOSE: Incisional hernia repair (IHR) with a mesh is necessary to achieve low recurrence rates and pain relief. In the short term, quality of life (QoL) is restored by IHR. Two centers pioneered the IHR in Sweden with the highly standardized Rives-Stoppa technique using a retromuscular mesh. We assessed long-term follow-up of recurrence rate and QoL. METHODS: Medical records were searched for IHRs performed from 1998 to 2006 and included living patients with midline repairs. Questionnaires about physical status, complaints, and QoL (SF-36) were mailed, offering a clinical examination. Assessment of medical records of later surgery was performed in 2015. RESULTS: Three hundred and one patients with midline incisional repairs were identified, and 217 accepted participation. Of these, 103 attended a clinical examination. Follow-up was 7 years until examination and 11 years to reassessment of medical records. In 26%, recurrent hernias were repaired. Postoperative complications were 26% Clavien-Dindo grade I-II and 1% grade III-IV. Mesh infections occurred in 1.4% without mesh removals, and 4% were reoperated because of complications. Overall recurrence rate was 8.1% and two-third of which were diagnosed at clinical examination. Recurrence after primary and recurrent hernia repair was 7.1 and 10.9%, respectively. Of all patients, 80% were satisfied; dissatisfaction was primarily caused by recurrence and chronic pain. SF-36 scores were 0.2 SD lower than the norm in all subscales, similar to those with 1-2 chronic conditions. CONCLUSIONS: Midline retromuscular mesh IHR has a low long-term recurrence rate even after recurrent repair. Patient satisfaction was high although QoL was reduced.

Short-term outcomes for open and laparoscopic midline incisional hernia repair: a randomized multicenter controlled trial: the ProLOVE (prospective randomized trial on open versus laparoscopic operation of ventral eventrations) trial.

OBJECTIVE: : The aim of the trial was to compare laparoscopic technique with open technique regarding short-term pain, quality of life (QoL), recovery, and complications. BACKGROUND: : Laparoscopic and open techniques for incisional hernia repair are recognized treatment options with pros and cons. METHODS: : Patients from 7 centers with a midline incisional hernia of a maximum width of 10 cm were randomized to either laparoscopic (LR) or open sublay (OR) mesh repair. Primary end point was pain at 3 weeks, measured as the bodily pain subscale of Short Form-36 (SF-36). Secondary end points were complications registered by type and severity (the Clavien-Dindo classification), movement restrictions, fatigue, time to full recovery, and QoL up to 8 weeks. RESULTS: : Patients were recruited between October 2005 and November 2009. Of 157 randomized patients, 133 received intervention: 64 LR and 69 OR. Measurements of pain did not differ, nor did movement restriction and postoperative fatigue. SF-36 subscales favored the LR group: physical function (P < 0.001), role physical (P < 0.012), mental health (P < 0.022), and physical composite score (P < 0.009). Surgical site infections were 17 in the OR group compared with 1 in the LR group (P < 0.001). The severity of complications did not differ between the groups (P < 0.213). CONCLUSIONS: : Postoperative pain or recovery at 3 weeks after repair of midline incisional hernias does not differ between LR and OR, but the LR results in better physical function and less surgical site infections than the OR does.

Risk factors for complications in groin hernia surgery: a national register study.

OBJECTIVE: This study aims to analyze and identify risk factors for postoperative complications and analyze the relative risk of reoperation for recurrence for respective complication. BACKGROUND: The outcome of groin hernia surgery is evaluated mostly by comparing recurrence rates and long-term pain. The aim of this observational population-based registry study was to identify risk factors for postoperative complications and analyze the relative risk of reoperation for recurrence for respective complication. METHODS: Using data from the nationwide Swedish Hernia Register between 1998 and 2009, 150,514 herniorrhaphies were analyzed with respect to postoperative complications occurring within 30 days of surgery. RESULTS: Risk factors significantly affecting the rate of postoperative complications were laparoscopic repair (odds ratio [OR] 1.35, 95% confidence interval [CI] 1.24-1.47) and open preperitoneal techniques (OR: 1.31, 95% CI: 1.15-1.49), with open anterior mesh as reference category. Other significant risk factors were general (OR: 1.30, 95% CI: 1.23-1.37) and regional anesthesia (OR: 1.53, 95% CI: 1.43-1.63), with local anesthesia as reference category, emergency procedures (OR: 1.53, 95% CI: 1.43-1.63); recurrent hernia repair (OR: 1.39, 95% CI: 1.27-1.52); femoral hernia (OR: 1.30, 95% CI: 1.14-1.48); aged older than 65 years (OR: 1.26, 95% CI: 1.21-1.31); and duration of surgery exceeding 50 minutes (OR: 1.27, 95% CI: 1.22-1.33). CONCLUSIONS: Open anterior approach and surgery under local anesthesia are associated with less risk of postoperative complications.

Early results of a single-blinded, randomized, controlled, Internet-based multicenter trial comparing Prolene and Vypro II mesh in Lichtenstein hernioplasty.

BACKGROUND: The standard polypropylene mesh used in Lichtenstein's operation induces a strong foreign-tissue reaction with potentially harmful effects. A mesh with less polypropylene could possibly be beneficial. PATIENTS AND METHODS: Six hundred men with inguinal hernias were randomized to Lichtenstein's operation with Prolene or Vypro II in a single-blinded multicenter trial. The randomization was performed by a computer algorithm in a database through the Internet. All data were entered and directly validated in the database through the Internet. RESULTS: The meshes had comparable results in return to work, return to daily activities, complications, postoperative pain, and quality of life during the first 8 weeks of rehabilitation. CONCLUSIONS: Lichtenstein's operation with either Prolene or Vypro II is safe and well tolerated with an acceptable postoperative rehabilitation time and a high quality of life 2 months after surgery. The study was facilitated by the use of a database through the Internet.
