Robot-assisted laparoscopic versus open middle pancreatectomy: short-term results of a randomized controlled trial
- 532 Downloads
This first prospective randomized controlled trial was performed to compare short-term outcomes of robot-assisted laparoscopic middle pancreatectomy (RA-MP) with open middle pancreatectomy (OMP).
RA-MP is a novel minimally invasive surgical technique for benign or borderline tumors in the pancreatic neck or body. Its short-term effectiveness and safety remain unknown, compared to OMP.
Patients eligible for MP from August 2011 to November 2015 were randomized into the RA-MP or OMP group. The primary endpoint was length of hospital stay (LOS). Secondary endpoints were intraoperative parameters, and postoperative and recovery variables.
A total of 100 patients were included into the study to analyze primary and secondary endpoints. Demographic characteristics and pathological parameters were similar in both groups. Furthermore, LOS was significantly shorter (15.6 vs. 21.7 days, P = 0.002), median operative time was reduced (160 vs. 193 min, P = 0.002), median blood loss was lower (50 vs. 200 mL, P < 0.001), rate of clinical postoperative pancreatic fistula (POPF) was lower (18 vs. 36.0 %, P = 0.043), nutritional status recovery was better, off-bed return to activity was expedited (3.1 vs. 4.6 days, P < 0.001), and resumption of bowel movement was faster (3.5 vs. 5.0 days, P < 0.001) in the RA-MP group, compared to the OMP group.
RA-MP was associated with significantly shorter LOS, reduced operative time, blood loss and clinical POPF rate, and expedited postoperative recovery, compared to OMP.
