Blind insertion of the Veress needle and of the first trocar is a significant cause of laparoscopic surgery complications. Despite this risk, the closed technique is still more popular than the open one. The authors retrospectively evaluated 1006 consecutive laparoscopic operations in which Hasson's technique was routinely performed. The overall complication rate was 2.2%, but the vast majority of complications occurred during the first 50 cases (6% vs. 1.9%). They conclude that after a learning phase of about 50 cases, Hasson's technique is a quick and safe procedure.
Veress针和第一套管针的盲目插入是腹腔镜手术并发症的一个重要原因。尽管存在这种风险，但闭合技术仍然比开放技术更受欢迎。作者回顾性评估了1006例连续进行的腹腔镜手术，其中常规采用Hasson技术。总体并发症发生率为2.2%，但绝大多数并发症发生在前50例手术中（6%对1.9%）。他们得出结论，经过约50例手术的学习阶段后，Hasson技术是一种快速且安全的手术方法。
