- Objective:The aim was to compare long-term postoperative pain after inguinal hernia surgery using 2 techniques that have shown favorable long-term outcome in previous randomized studies: Lichtenstein using local anesthesia (LLA) and endoscopic total extra-peritoneal repair (TEP) under general anesthesia.Background:Patients often experience pain after inguinal hernia surgery. These 2 methods in their optimal state have not yet been sufficiently compared.Methods:A randomized controlled trial was conducted to detect any difference in long-term postoperative inguinal pain. Altogether 384 patients were randomized and operated using either TEP under general anesthesia (n=193) or LLA (n=191). One year postoperatively, patients were examined by an independent surgeon and requested to complete the Inguinal Pain Questionnaire (IPQ), a validated questionnaire for the assessment of postoperative inguinal pain.Results:Three hundred seventy-five (97.7%) patients completed follow-up at 1 year. In the TEP group, 39 (20.7%) patients experienced pain, compared with 62 (33.2%) patients in the LLA group (P=0.007). Severe pain was reported by 4 patients in the TEP group and 6 patients in the LLA group (2.1% and 3.2%, respectively, P=0.543). Pain in the operated groin limited the ability to exercise for 5 TEP patients and 14 LLA patients (2.7% and 7.5%, respectively, P=0.034).Conclusions:Patients operated with TEP experienced less long-term postoperative pain and less limitation in their ability to exercise than those operated with LLA. The present data justify recommending TEP as the procedure of choice in the surgical treatment of primary inguinal hernia.

- OBJECTIVE: To assess the incidence of intestinal mucosal injury during faecal peritonitis in pigs, the relation of such lesions to haemodynamic variables, intramucosal pH (pHi), and endothelial adherence of polymorphonuclear leucocytes (PMNs). DESIGN: Experimental laboratory study. SETTING: University department of surgery, Sweden. SUBJECTS: 57 Juvenile pigs. INTERVENTIONS: Pigs had faecal peritonitis induced (n = 39) or a sham procedure (n = 18). In addition, 15 animals were pretreated with the monoclonal CD18 receptor antibody IB4 before induction of peritonitis with the aim of preventing tissue accumulation of PMNs. MAIN OUTCOME MEASURES: Development of mucosal lesions and correlation with haemodynamic variables. RESULTS: 17/18 (94%) of control animals had normal mucosa. The incidence of mucosal lesions in animals with faecal peritonitis was 56%. Animals with severe mucosal injury (grade 4-5) had significantly lower mean arterial pressure, cardiac index, and pHi during the last hour of the experiment compared with animals without mucosal lesions. Pretreatment with IB4 did not prevent the development of intestinal mucosal injuries. Intramucosal pH decreased during sepsis and was not affected by IB4. CONCLUSIONS: Severe intestinal mucosal injury is associated with arterial hypotension, low cardiac index, and low pH. Neither the mucosal injury nor the reduction in pHi seen during porcine faecal peritonitis seemed to be leucocyte-related phenomena.
