BackgroundChronic pain is the main drawback of the Lichtenstein procedure for inguinal hernia repair, with a reported incidence of 15–40%. The transinguinal pre-peritoneal (TIPP) technique seems to be associated with less chronic pain, comparable to the total extra peritoneal (TEP) technique. The aim of this study was to evaluate 3 years of TIPP and Lichtenstein experience since the start of our Hernia Center Brabant in January 2006.MethodsPatient records of unilateral primary inguinal anterior hernia corrections (TIPP and Lichtenstein) performed since the opening of Hernia Center Brabant (2006–2008) were evaluated in a retrospective study. ASA class 4 and 5, <18 years, recurrences and bilateral hernias were excluded. In the TIPP technique, a Polysoft™ Hernia Patch was placed into the preperitoneal space using an anterior protocol led approach. The Lichtenstein technique was performed as described by Amid [Amid et al (1996) Eur J Surg 162:447–453] and modified with a soft mesh. One of the hernia surgeons decided peroperatively which technique to perform. Baseline characteristics and postoperative complications were assessed retrospectively. The attempted follow up period was 6 months. Chronic pain was assessed in both groups as mild (VAS 1–3), moderate (VAS 4–6) or severe (VAS 7–10). Chronic pain was defined in both groups as any pain sensation lasting longer than 3 months postoperatively, or when local injection of analgesia was necessary. Patients who did not come back because of chronic pain after regular follow up were regarded as free of pain.ResultsA total of 496 patients were included in this study; 225 TIPP and 271 Lichtenstein anterior inguinal hernia operations were analyzed. Data from one TIPP-patient were lost. Both groups were comparable with regard to baseline characteristics regarding age (p = 0.059), gender (p = 0.478) and ASA-classification (p = 0.104). TIPP: mean age 52.7 years, ASA-classification I: 54%, II: 36% and III: 5.3%. A total of 7.6% complications were assessed; recurrence (n = 1), bleeding (and re-operation) (n = 4); 10 patients (4.4%) experienced chronic pain. Persisting sensation loss occurred in 0.9%. Lichtenstein: mean age 57.3 years, ASA-classification I: 51%, II: 38% and III: 11%. A total of 8.5% complications were assessed; recurrence (n = 3), bleeding (and re-operation) (n = 3); 11 Lichtenstein patients (4.1%) experienced chronic pain. Persisting sensation loss occurred in 2.2%. Limitations of this retrospective study were incomplete follow up (31.3% had only one post operative visit 14 days after surgery) and these patients were further regarded as free of pain. Therefore, possible under-reporting of chronic pain could be present. The study was not double blind.ConclusionThis retrospective study design revealed no significantly better results for the TIPP procedure as compared to the Lichtenstein technique. The incidence of chronic pain reported in this retrospective study has been low in both groups since the opening of the Hernia Center Brabant. These results form the basis...

Background Despite the fact that primary percutaneous catheter drainage has become standard practice, some patients with pancreatic fistula after pancreatoduodenectomy ultimately undergo a relaparotomy. The aim of this study was to compare completion pancreatectomy with a pancreas-preserving procedure in patients undergoing relaparotomy for pancreatic fistula after pancreatoduodenectomy. Methods This retrospective cohort study of nine institutions included patients who underwent relaparotomy for pancreatic fistula after pancreatoduodenectomy from 2005–2018. Furthermore, a systematic review and meta-analysis were performed according to the PRISMA guidelines. Results From 4877 patients undergoing pancreatoduodenectomy, 786 (16 per cent) developed a pancreatic fistula grade B/C and 162 (3 per cent) underwent a relaparotomy for pancreatic fistula. Of these patients, 36 (22 per cent) underwent a completion pancreatectomy and 126 (78 per cent) a pancreas-preserving procedure. Mortality was higher after completion pancreatectomy (20 (56 per cent) versus 40 patients (32 per cent); P = 0.009), which remained after adjusting for sex, age, BMI, ASA score, previous reintervention, and organ failure in the 24 h before relaparotomy (adjusted odds ratio 2.55, 95 per cent c.i. 1.07 to 6.08). The proportion of additional reinterventions was not different between groups (23 (64 per cent) versus 84 patients (67 per cent); P = 0.756). The meta-analysis including 33 studies evaluating 745 patients, confirmed the association between completion pancreatectomy and mortality (Mantel–Haenszel random-effects model: odds ratio 1.99, 95 per cent c.i. 1.03 to 3.84). Conclusion Based on the current data, a pancreas-preserving procedure seems preferable to completion pancreatectomy in patients in whom a relaparotomy is deemed necessary for pancreatic fistula after pancreatoduodenectomy.
