Abstract:
Objective To develop a staged laparoscopic training program for performing the ana-tomic retroperitoneoscopic adrenalectomy(ARA), and to determine its safety and feasibility. Me-thods Five young urological doctors without previous experience in open adrenalectomy were selected third period, trainees acted as camera holder first, then performed simple operations such as laparo-scopic renal cyst unroofing. Finally, they performed 30 ARA independently under the mentor's super-vision. Pheochromocytoma was ruled out for its large tumor size and potential cardiovascular risk. The patient selection criteria were the same as those of the initial 30 cases performed by the tutor. Preope-rative data of the initial 30 ARA performed by each trainee and tutor which included gender, age, body mass index, tumor size, tumor location and pathological diagnosis of tumor were compared between trainees and the tutor. The intraoperative and postoperative data of 150 ARA in the trainees were compared with the initial 30 ARA of the tutor. These included mean operative time, estimated blood loss, length of hospital stay, conversion rate, complication rate. Qualitative and quantitative data were compared between the groups using x2 and t test statistics methods by SPSS 12.0 for Windows, except operative time, which was from a nonnormal distribution. A P value less than 0.05 was consi-dered to be statistically significant. Results Preoperative data of the initial 30 ARA performed by each trainee were marched to those of the mentor (all P>0.05). All ARA were completed successful-ly. No procedure converted to open surgery. The median operative time of the trainees was 82 min (range 59-133 min), which was less than that of the tutor [132 min (range 73-230 min), P< 0.01]. And the trainees' learning curve was flatter than their tutor's. Estimated blood loss and length of hospital stay for the 5 trainees and the tutor were 62.2±22.0 ml, 4.8±1.3 d and 63.9±21.1 ml, 4.5±1.4 d respectively. There was no significant difference between these results (both P>0.05). No major complication was observed. Though the total perioperative complication rates were no diffe-rence between the trainees and their tutor (8.0% versus 13.3%, P>0.05), intraoperative minor complication rates of the trainees (1.3%) was less than that of the tutor (10.0%, P<0.05). Con-clusion The staged laparoscopic training is safe and feasible for young urological doctor to study in performing ARA.
