Laparoscopic approach in emergency for the treatment of acute incarcerated groin hernia: a systematic review and meta-analysis.

Abstract

Minimally invasive approach for acute incarcerated groin hernia repair is still debated. To clarify this debate, a literature review was performed. Search was performed in PubMed, Embase, Scopus, Web of Science, and Cochrane databases, founding 28,183 articles. Fifteen articles, and 433 patients were included (16 bilateral hernia, range 3-8). Three hundred and eighty-eight (75.3%) and 103 patients (22.9%) underwent transabdominal preperitoneal and totally extraperitoneal repair, respectively, and in 5 patients, the defect was buttressed with broad ligament (1.1%) (not specified in 3 patients). Herniated structures were resected in 48 cases (range 1-9). Intraoperative complications and conversion occurred in 4 (range 0-1) and 10 (range 0-3) patients, respectively. Mean operative time and hospital stay ranged between 50 and 147min, and 2 and 7days, respectively. Postoperative complications ranged between 1 and 19. Five studies compared laparoscopic and open approaches (163 and 235 patients). Herniated structures were resected in 19 (11.7%) and 42 cases (17.9%) for laparoscopic and open approach, respectively (p = 0.1191). Intraoperative complications and conversion occurred in one (0.6%) and 5 (2.1%) patients (p = 0.4077), and in two (1.2%) and 19 (8.1%) patients (p = 0.0023), in case of laparoscopic or open approach, respectively. Mean operative time and hospital stay were 94.4 ± 40.2 and 102.8 ± 43.7min, and 4.8 ± 2.2 and 11 ± 3.1days, in laparoscopic or open approach, respectively. Sixteen (9.8%) and 57 (24.3%) postoperative complications occurred. Laparoscopy seems to be a safe and feasible approach for the treatment of acute incarcerated groin hernia. Further studies are required for definitive conclusions.
