RESUMO
BACKGROUND: Complications associated with sutured mesh fixation following open groin hernia repair have prompted surgeons to evaluate methods of atraumatic fixation such as the use of human fibrin glue. Small trials with Tissucol/Tisseel fibrin glue (Baxter Healthcare, Deerfield, IL, USA) have shown promising results that warrant further investigation. METHODS: TIMELI (Tissucol/Tisseel for MEsh fixation in LIchtenstein hernia repair) is an international, controlled, randomized, patient- and evaluator-blinded study that is comparing mesh fixation with Tissucol or sutures in patients with inguinal hernia. The primary endpoint evaluates the incidence of disabling complications (chronic pain and/or numbness and/or groin discomfort) at 12 months post-surgery. RESULTS: Patient enrolment started in February 2006 and ended on 19 April 2007, with a total of 325 patients recruited. Initial results are expected in early 2008. CONCLUSIONS: TIMELI is a major international trial that will provide important information on the efficacy and safety of Tissucol, compared with sutures, for mesh fixation in patients undergoing Lichtenstein technique for primary inguinal hernia repair.

After reviewing the available classifications for groin hernias, the European Hernia Society (EHS) proposes an easy and simple classification based on the Aachen classification. The EHS will promote the general and systematic use of this classification for intraoperative description of the type of hernia and to increase the comparison of results in the literature.

PURPOSE: The Tisseel/Tissucol for mesh fixation in Lichtenstein hernia repair (TIMELI) study showed that mesh fixation with human fibrin sealant during inguinal hernia repair significantly reduced moderate-severe complications of pain 12 months post-operatively compared with sutures. Further analyses may assist surgeons by investigating predictors of post-surgical complications and identifying patients that may benefit from Tisseel/Tissucol intervention. METHODS: Univariate and multivariate analyses identified risk factors for combined pain, numbness and groin discomfort (PND) visual analogue scale (VAS) score 12 months post-operatively. Variables tested were: fixation method, age, employment status, physical activity, nerve handling, PND VAS score at pre-operative visit and 1 week post-operatively. The effect of fixation technique on separate PND outcomes 12 months post-surgery was also assessed. Analyses included the intention-to-treat (ITT) population and a subpopulation with pre-operative PND VAS > 30 mm. RESULTS: 316 patients were included in the ITT, with 130 patients in the subpopulation with pre-operative PND VAS > 30. Multivariate analysis identified mesh fixation with sutures, worsening pre-operative PND and worsening PND 1 week post-surgery as significant predictors of 12-month PND in the ITT population; mesh fixation with sutures was a significant predictor of 12-month PND in the pre-operative PND VAS > 30 subpopulation (p < 0.05). Mesh fixation with Tisseel/Tissucol resulted in significantly less numbness and a lower intensity of groin discomfort compared with sutures at 12 months; there was no difference in pain between the treatment groups. CONCLUSIONS: Pre-operative discomfort may be an important predictor of post-operative pain, numbness and discomfort. Tisseel/Tissucol may improve long-term morbidity over conventional sutures in these patients.

PURPOSE: A classification for primary and incisional abdominal wall hernias is needed to allow comparison of publications and future studies on these hernias. It is important to know whether the populations described in different studies are comparable. METHODS: Several members of the EHS board and some invitees gathered for 2 days to discuss the development of an EHS classification for primary and incisional abdominal wall hernias. RESULTS: To distinguish primary and incisional abdominal wall hernias, a separate classification based on localisation and size as the major risk factors was proposed. Further data are needed to define the optimal size variable for classification of incisional hernias in order to distinguish subgroups with differences in outcome. CONCLUSIONS: A classification for primary abdominal wall hernias and a division into subgroups for incisional abdominal wall hernias, concerning the localisation of the hernia, was formulated.
