Abstract
OBJECTIVE: To analyze the feasibility and safety of Natural Orifice Transluminal Endoscopic Surgery (NOTES) appendectomy, and to analyze separately the transvaginal appendectomy (TVAE) and the transgastric appendectomy (TGAE) procedures. BACKGROUND: Laparoscopic appendectomy has rare but relevant complications, namely incisional hernias and neuralgia at the trocar sites, which can potentially be avoided by the NOTES techniques. METHODS: The first 217 data sets of the largest NOTES registry worldwide-the German NOTES registry-were analyzed with respect to demographic data, procedural data, and short-term outcomes. Furthermore, TVAEs were compared with TGAEs. RESULTS: Almost all procedures were performed in hybrid technique (median of percutaneous trocars: 1). Median age (TVAE: 30.5 yrs vs TGAE: 25 yrs; P < 0.017), body mass index (TVAE: 22.8 kg/m vs TGAE: 24.1 kg/m; P < 0.016), and American Society of Anesthesiologists (ASA) classification (I/II/III; TVAE: 57.1%/41.8%/1.0% vs TGAE: 27.8%/69.4%/2.8%; P < 0.003) significantly differed between both access techniques. Whereas the median number of percutaneous trocars (TVAE: 1 vs TGAE: 1; P < 0.450), the need of additional trocars (TVAE: 6.6% vs TGAE: 13.9%; P < 0.156), the intra, and also postoperative rate of complications (TVAE: 0%/5.5% vs TGAE: 0%/11.1%; P < 1.000/0.258), and the median postoperative hospital stay (TVAE: 3 d vs TGAE: 3 d; P < 0.152) were comparable; the median procedural time (TVAE: 35 minutes vs TGAE: 96 minutes; P < 0.001) and conversion to laparotomy rate (TVAE: 0% vs TGAE: 5.6%; P < 0.023) were significantly less after TVAE. CONCLUSIONS: The evaluation of the largest patient collective so far indicates that hybrid NOTES appendectomy is a safe procedure, with advantages for the transvaginal technique with respect to procedural time and conversion rate.
