Table 2. Spleen preservation rate of conventional laparoscopy and robot groups before and after learning curve (n=16) for laparoscopic distal pancreatectomy.
| Distal pancreatectomy | P value | ||
|---|---|---|---|
| Laparoscopy | Robot | ||
| Before learning curve | |||
| Spleen preservation [n/N (%)] | 8/16 (50.0) | 16/16 (93.8) | 0.015 |
| Splenic vessel conservation [n/N (%)] | 8/16 (50.0) | 13/16 (81.3) | 0.009 |
| After learning curve | |||
| Spleen preservation [n/N (%)] | 20/25 (80.0) | 19/21 (94.7) | 0.428 |
