Gasless transumbilical laparoscopic-assisted appendectomy as a safe and cost-effective alternative surgical procedure for mild acute appendicitis

摘要

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.
