Abstract

Purpose: Several reports have demonstrated the effectiveness and feasibility of single incisional transumbilical laparoscopic-assisted appendectomy (TULAA). We developed a modified TULAA technique, gasless-TULAA, which involves lifting the abdominal wall with a retractor, without pneumoperitoneum or another incision. Methods: We assessed the surgical outcomes of 257 patients treated for appendicitis in our hospital between 2005 and 2013. In a preoperative comprehensive evaluation, appendicitis without abscess was defined as mild appendicitis (mild appendicitis group: MAG), and appendicitis with abscess was defined as severe appendicitis (severe appendicitis group: SAG). The clinical outcomes were compared with those in other published reports. The cost-effectiveness of gasless-TULAA was compared with that of conventional multiport laparoscopic appendectomy (CMLA) in our hospital. Results: In MAG (n = 228), the operation time and postoperative hospital stay were 46.9 ± 22.7 min and 2.6 ± 1.2 days, respectively. The gasless-TULAA was completed without trocars in 91.2 % of patients. The surgical outcomes of SAG were significantly worse than those of MAG (p < 0.001). The surgical cost of gasless-TULAA was significantly lower than that of CMLA (p < 0.001). Conclusion: Gasless-TULAA is a cost-effective, safe, and readily available surgical technique for mild appendicitis, which can obviate the need for specialized equipment.
