Analysis of postoperative pain in robotic versus traditional laparoscopic hysterectomy.

Abstract

The aim of this study was to assess postoperative pain and narcotic use in the first 23h following robotic versus traditional laparoscopic hysterectomy for benign pathology. The study design was that of a retrospective case-control study of robotic (first 100 consecutive) versus traditional (last 100 consecutive) total laparoscopic hysterectomy cases at an obstetrics and gynecology multi-institutional community practice. Patient characteristics were equivalent in both groups (age, p=0.364; body mass index, p=0.326; uterine weight, p=0.565), except for a higher number of Caucasians in the traditional laparoscopic group (p=0.017). Compared to patients who underwent robotic laparoscopic hysterectomy, those who underwent the traditional procedure had higher visual analog scale pain scores (3.1±1.5 vs. 4.6±2.4, respectively; p<0.001) and used more narcotics (27.5 vs. 35.4mg hydrocodone, respectively; p<0.05). Factors that could potentially increase pain (more procedures, more ports, total incision size, and longer operative time) were significantly higher in the robotic group, but only surgical approach, amount of narcotic, and age correlated with pain levels when evaluated with regression analysis. Complication rates were equivalent between groups. In conclusion, patients who underwent robotic assisted laparoscopic hysterectomy had statistically decreased postoperative pain scores and narcotic use than those who underwent the traditional laparoscopic approach, even when the robotic cases involved more procedures and ports and were associated with longer operative time.
