摘要

Background

The specimen extraction incision is the largest during minimally invasive colectomy and conceivably the most painful. We recently adopted natural orifice extraction through the rectum or vagina, leaving only port site incisions for abdominal wall pain. Previous studies demonstrating natural orifice extraction advantages are inconclusive. The study aim was to determine if natural orifice specimen extraction is associated with less pain and opioid use than abdominal wall specimen extraction after enhanced recovery robotic anterior (sigmoid) resection for benign disease.

Methods

This is a single-institution retrospective analysis comparing abdominal wall and natural orifice extraction sites after robotic anterior resection for diverticular disease in a prospectively maintained institutional colorectal surgery database from 1/1/2021 to 11/21/2024. The primary outcomes were postoperative opioid use measured by morphine milliequivalents analyzed with generalized linear models and postoperative pain scores analyzed with ordinal logistic regression models.

Results

There were 251 anterior (sigmoid) resections for diverticular disease, 136 patients with abdominal wall specimen extraction sites, and 115 patients with natural orifice extraction. Patient characteristics were well matched between groups. One-fifth (20.7%) of the study population required no postoperative opioids. There was no significant difference in postoperative opioids, measured by morphine milliequivalents, between natural orifice and abdominal wall extraction site groups (aOR1.21, p = 0.59). Lower preoperative pain (aOR0.73, p = 0.02) and better mental health (aOR1.05, p = 0.05) were associated with no postoperative opioids. Patient-reported preoperative PROMIS-10 pain scores and younger age were associated with higher postoperative numeric pain scores. There was no significant difference in postoperative complications between groups (abdominal wall 8.1% vs natural orifice 13.0%).

Conclusion

There was no significant difference between abdominal wall and natural orifice extraction in postoperative pain, postoperative opioids, and complications after robotic anterior resection for diverticular disease. These data may assist targeting postoperative pain solutions and counsel patients considering specimen extraction site options.
