ABSTRACT

PURPOSE: The hypothesis of this meta-analysis was to assess whether laparoscopic approach shows real benefits over Lichtenstein technique in recurrent inguinal hernia repair. METHODS: A literature search for prospective randomized trials comparing laparoscopic and Lichtenstein procedure in recurrent inguinal hernia repair was performed. Trials were reviewed for primary outcome measures: re-recurrence, chronic inguinal pain and ischemic orchitis; and for secondary outcome measures. Standardized mean difference (SMD) was calculated for continuous variables and odds ratio for dichotomous variables. RESULTS: Seven studies comparing laparoscopic and Lichtenstein technique were considered suitable for the pooled analysis. Overall 647 patients with recurrent inguinal hernia were randomized to either laparoscopic repair (333, 51.5 %, transabdominal preperitoneal approach, TAPP and totally extraperitoneal approach, TEP) or anterior open repair (314, 48.5 %, Lichtenstein operation). Patients who underwent laparoscopic repair experienced significantly less chronic pain (9.2 % vs. 21.5 %, p = 0.003). Patients of the laparoscopic group had a significantly earlier return to normal daily activities (13.9 vs. 18.4 days, SMD = -0.68, 95 % CI = -0.94 to -0.43, p < 0.000001). Operative time was significantly longer in laparoscopic operations (62.9 vs. 54.2 min, SMD 0.46, 95 % CI 0.03, 0.89; p = 0.04). No other differences were found. CONCLUSIONS: Laparoscopy showed reduced chronic inguinal pain and an earlier return to normal daily activities but significantly longer operative time. Despite the expected advantages, the choice between laparoscopy and other techniques still depends on local expertise availability. Only dedicated centers are able to routinely offer laparoscopy for recurrent inguinal hernia repair.

ABSTRACT

BACKGROUND: Encapsulated papillary thyroid carcinoma (EPTC) is commonly retained as a tumor with indolent clinical courses. Herein we focused on the search for factors predicting biological behavior and influencing prognosis of EPTC in comparison with the non-encapsulated counterpart of papillary thyroid carcinoma (NEPTC). METHODS: From January 1998 to May 2009, 348 patients underwent thyroidectomy in our surgical department because of papillary thyroid carcinoma (PTC). A cross-sectional study of 52 patients with EPTC and 296 patients with NEPTC was carried out: demographic data, tumor characteristics, diagnostic results, patient management, post-operative and follow-up results were evaluated. RESULTS: EPTC patients were significantly younger than patients with NEPTC (44.5 vs 48.8 yr, p<0.04). Mean tumor size was significantly greater for EPTC than for NEPTC (2.36 vs 1.41 cm, p<0.001). Tumor multifocality, thyroid capsular invasion, and lymph node involvement at diagnosis were significantly associated with NEPTC (p=0.0001, p<0.0001, and p=0.027, respectively). Multivariate analyses showed that NEPTC classical variant were at risk for both thyroid capsular invasion and nodal involvement (odds ratio 6.870 and 9.514, respectively) while EPTC were not. Nodal metastasis at diagnosis was the only factor influencing recurrence. CONCLUSIONS: The majority of EPTC had risk-free clinical courses as a result of their low risk of locoregional spread. However, definitive recommendations need a longer follow-up and a comparison with a lesser treated group of patients belonging to the same category of risk at diagnosis.
