To explore the application of one-step trocar insertion visibility for observation port establishment in transperitoneal laparoscopic adrenalectomy.

A retrospective analysis was conducted by collecting the data of 26 patients who had been performed transperitoneal laparoscopic adrenalectomy from April 2015 to December 2017. One-step trocar insertion visibility were performed for the observation group(13 cases), while conventional open incision(Hasson) method was used for the control group(13 cases). The same process was performed in subsequent adrenalectomy. The time of trocar insertion, operation time(removal of adrenal gland), total operation time, blood loss, post-operative fasting time, post-operative drainage time, and the hospitalization time after operation between two groups were compared.

Operations were successfully performed in all cases, and no patient was converted to open surgery. The time of trocar insertion and total operation process in observation group were less than control group. However, between two groups, there were no significant differences in time of removal of adrenal gland, blood loss, post-operative fasting time, drainage and the hospitalization time after operation.

One-step trocar insertion visibility to establish observation port in transperitoneal laparoscopic adrenalectomy is safe and effective which can reduce the time of trocar insertion and total operation process, improve the safety of the operation as well.
