Needlescopic versus laparoscopic appendectomy: a systematic review Sajid MS; Khan MA; Cheek E; Baig MKCan J Surg 2009[Apr]; 52 (2): 129-34BACKGROUND: Needlescopic appendectomies (NA) have been performed since the 1990s. We sought to systematically analyze trials comparing NA with laparoscopic appendectomies (LA) in the management of appendicitis. METHODS: We performed a systematic review of the literature. We compared and analyzed clinical trials on NA and LA to generate summative data expressed as standardized mean differences (SMD). RESULTS: Of 5 retrieved trials from the electronic database 2 trials involving 412 patients met our inclusion criteria. In the fixed-effects models, NA took longer than LA, and this time difference was statistically significant: SMD 0.20 min, 95% confidence interval 0.01-0.40, p = 0.030, z(1) = 2.09. In both fixed-and random-effects models, the difference in total hospital stay and in perioperative complications between the NA and LA groups were nonsignificant. Furthermore, in both fixed-and random-effects models, NA was associated with a higher conversion rate to open appendectomy than LA. There was no heterogeneity between the trials (Q = 0.34, p = 0.55). CONCLUSION: Needlescopic appendectomy can be a safe and effective procedure for the management of appendicitis. It is comparable to LA in terms of hospital stay and perioperative complications. However, NA is associated with a longer duration of surgery and a higher conversion rate, indicating technical challenges of the procedure. Before recommending routine use of the needlescopic technique for appendectomy, a major multicentre randomized controlled trial is necessary.|*Laparoscopy[MESH]|Appendectomy/*instrumentation/*methods[MESH]|Appendicitis/surgery[MESH]|Clinical Trials as Topic[MESH]|Humans[MESH]|Length of Stay[MESH]|Postoperative Complications[MESH] |
