The role of the laparoendoscopic single site totally extraperitoneal approach to inguinal hernia repairs: a review and meta-analysis of the literature.

BACKGROUND: Laparoendoscopic single site (LESS) surgery may have perceived benefits of reduced visible scarring compared to conventional laparoscopic (LAP) totally extraperitoneal (TEP) hernia repairs. We reviewed the literature to compare LESS TEP inguinal hernia repairs with LAP TEP repairs. METHODS: We searched electronic databases for research published between January 2008 and January 2012. RESULTS: A total of 13 studies reported on 325 patients. The duration of surgery was 40-98 minutes for unilateral hernia and 41-121 minutes for bilateral repairs. Three studies involving 287 patients compared LESS TEP (n = 128) with LAP TEP (n = 159). There were no significant differences in operative duration for unilateral hernias (p = 0.63) or bilateral repairs (p = 0.29), and there were no significant differences in hospital stay (p > 0.99), intraoperative complications (p = 0.82) or early recurrence rates (p = 0.82). There was a trend toward earlier return to activity in the LESS TEP group (p = 0.07). CONCLUSION: Laparoendoscopic single site surgery TEP hernia repair is a relatively new technique and appears to be safe and effective. Advantages, such as less visible scarring, mean patients may opt for LESS TEP over LAP TEP. Further studies with clear definitions of outcome measures and robust follow-up to assess patient satisfaction, return to normal daily activities and recurrence are needed to strengthen the evidence.

CONTEXTE: La chirurgie laparoendoscopique à orifice unique (LESS) a comme avantage perçu une réduction des cicatrices apparentes comparativement aux réparations laparoscopiques (LAP) classiques totalement extrapéritonéales (TEP) des hernies. Nous avons passé en revue la littérature afin de comparer les réparations des hernies inguinales par chirurgie LESS TEP et par LAP TEP. MÉTHODES: Nous avons interrogé les bases de données électroniques pour y recenser la recherche publiée entre janvier 2008 et janvier 2012. RÉSULTATS: En tout, 13 études ont porté sur 325 patients. La durée de la chirurgie a été de 40 à 98 minutes pour les réparations de hernies unilatérales et de 41 à 121 minutes pour les réparations de hernies bilatérales. Trois études regroupant 287 patients ont comparé la technique LESS TEP (n = 128) à la technique LAP TEP (n = 159). On n'a observé aucune différence significative quant à la durée de la chirurgie des réparations de hernies unilatérales (p = 0,63) ou bilatérales (p = 0,29) et aucune différence significative de durée des séjours hospitaliers (p > 0,99), de complications peropératoires (p = 0,82) ou de taux de récurrences précoces (p = 0,82). On a noté une tendance à un retour plus rapide aux activités dans le groupe soumis à la technique LESS TEP (p = 0,07). CONCLUSION: La réparation de hernie par chirurgie TEP laparoendoscopique à un seul orifice est une technique relativement nouvelle et semble sécuritaire et efficace. Ses avantages, par exemple des cicatrices moins apparentes, pourraient pousser les patients à opter pour la technique LESS TEP plutôt que LAP TEP. Il faudra procéder à d'autres études fondées sur des définitions paramétriques claires et comportant un suivi robuste pour évaluer la satisfaction des patients, la reprise des activités quotidiennes normales et les taux de récurrences afin de consolider les preuves.

Extracorporeal shock wave therapy is effective in treating chronic plantar fasciitis: a meta-analysis of RCTs.

BACKGROUND: Plantar fasciitis is the most common cause of heel pain. It may remain symptomatic despite conservative treatment with orthoses and analgesia. There is conflicting evidence concerning the role of extracorporeal shock wave therapy (ESWT) in the management of this condition. QUESTIONS/PURPOSES: We investigated whether there was a significant difference in the change of (1) VAS scores and (2) Roles and Maudsley scores from baseline when treated with ESWT and placebo. Specifically we compared overall improvement from baseline composite VAS, reduction in overall VAS pain, success rate of improving overall VAS pain by 60%, success rate of improving VAS pain by 60% when taking first steps, doing daily activities, and during application of a pain pressure meter. METHODS: MEDLINE, Embase, and CINAHL databases were searched from January 1980 to January 2013 and a double extraction technique was used to obtain relevant studies. Studies had to be prospective randomized controlled trials on adults and must not have used local anesthesia as part of their treatment protocol. Studies must have specifically recruited patients who continued to be symptomatic despite a minimum of 3 months of conservative treatments. All papers were assessed regarding their methodologic quality and a meta-analysis performed. Seven prospective randomized controlled trials were included in this study. There were 369 patients included in the placebo group and 294 in the ESWT group. RESULTS: After ESWT, patients had better composite VAS scores (random effects model, standardized mean difference [SMD] = 0.38; 95% CI, 0.05, 0.72; z = 2.27). They also had a greater reduction in their absolute VAS scores compared with placebo (random effects model, SMD = 0.60; 95% CI, 0.34, 0.85; z = 4.64). Greater success of improving heel pain by 60% was observed after ESWT when taking first steps (random effects model, risk ratio [RR] = 1.30; 95% CI, 1.04, 1.62; z = 2.29) and during daily activities (random effects model, RR = 1.44; 95% CI, 1.13, 1.84; z = 2.96). Subjective measurement of pain using a pressure meter similarly favored ESWT (random effects model, RR = 1.37, 95% CI, 1.06, 1.78; z = 2.41). There was a significant difference in the change to "excellent - good" Roles and Maudsley scores in favor of the ESWT group. CONCLUSIONS: ESWT is a safe and effective treatment of chronic plantar fasciitis refractory to nonoperative treatments. Improved pain scores with the use of ESWT were evident 12 weeks after treatment. The evidence suggests this improvement is maintained for up to 12 months. We recommend the use of ESWT for patients with substantial heel pain despite a minimum of 3 months of nonoperative treatment.

A literature review on the role of totally extraperitoneal repairs for groin pain in athletes.

A literature review was made on the role of totally extraperitoneal (TEP) hernia repairs for groin pain in athletes. Electronic databases were searched for literature published from January 1993 to November 2011. There were 10 articles incorporating 196 patients included in this review. Thirty percent of patients were reported to have direct inguinal hernias, 22% had indirect inguinal hernias, and 41% had dilated internal rings. Of note, 30% of cases had no macroscopic abnormality. Four studies reported on an early follow-up ranging between 3 and 6 weeks. Only minimal or mild symptoms were reported. Up to 33% of patients had impaired ability to perform at peak levels. Up to 53% of patients had persistence of symptoms at the early follow-up. Total follow-up time ranged from 3 to 80 months, and most patients were active (90%-100%). At long-term follow-up, 3% to 10% were unable to play, and 5% were reported as being unable to train. Two studies from the same center reported on TEP surgery for osteitis pubis, and most patients returned to sporting activity after 4 to 8 weeks. TEP repair is a good operative intervention in athletes with chronic groin pain not relieved by conservative measures. Athletes recover quickly and return to sport early.
