摘要
We compared the nodal yield and volume of target tissue removed in 3 groups of patients undergoing laparoscopic pelvic lymphadenectomy as a staging procedure for carcinoma of the prostate. With the exception of the type of peritoneotomy used to expose the obturator fossa, surgical management of all patients was identical. Results were evaluated in patients undergoing linear peritoneotomy (40), inverted V peritoneotomy (14) or both procedures (28, 1 approach on each side). Significantly more tissue was removed from patients in the inverted V group (16.3 +/- 8.3 cm. 3) compared to the linear peritoneotomy group (7.2 +/- 5.7 cm.3, p = 0.004). This resulted in a significant increase in nodal yield in patients in the inverted V group (11.0 +/- 4.1) relative to the linear peritoneotomy group (6.8 +/- 5.2, p = 0.003). In terms of the volume of tissue removed and the number of nodes obtained, combination patients had values intermediate to those in the other groups (11.6 +/- 10.5 cm.3 and 8.8 +/- 5.6 nodes, respectively). The right-to-left ratio of nodes and tissue volume was reversed in the combination group relative to the other 2 groups. Operative time was significantly decreased for the inverted V technique compared to the linear peritoneotomy approach (p = 0.01). No difference in operative blood loss or complications was identified. The improved exposure obtained with this technique appears to result in a more complete lymphadenectomy without increased risk of complications.
