Implementing enhanced recovery protocols for gynecologic surgery


 

“Enhanced Recovery After Surgery” (ERAS) practices and protocols have been increasingly refined and adopted for the field of gynecology, and there is hope among gynecologic surgeons – and some recent evidence – that, with the ERAS movement, we are improving patient recoveries and outcomes and minimizing the need for opioids.

This applies not only to open surgeries but also to the minimally invasive procedures that already are prized for significant reductions in morbidity and length of stay. The overarching and guiding principle of ERAS is that any surgery – whether open or minimally invasive, major or minor – places stress on the body and is associated with risks and morbidity.

Enhanced Recovery After Surgery protocols

Enhanced recovery protocols are multidisciplinary, perioperative approaches designed to lessen the body’s stress response to surgery. The protocols and pathways offer us a menu of small changes that, in the aggregate, can lead to large and demonstrable benefits – especially when these small changes are chosen across the preoperative, intraoperative, and postoperative arenas and then standardized in one’s practice. Among the major components of ERAS practices and protocols are limiting preoperative fasting, employing multimodal analgesia, encouraging early ambulation and early postsurgical feeding, and creating culture shift that includes greater emphasis on patient expectations.

In our practice, we are incorporating ERAS practices not only in hopes of reducing the stress of all surgeries before, during, and after, but also with the goal of achieving a postoperative opioid-free hysterectomy, myomectomy, and extensive endometriosis surgery. (All of our advanced procedures are performed laparoscopically or robotically.)

Over the past 7 or so years, we have adopted a multimodal approach to pain control that includes a bundle of preoperative analgesics – acetaminophen, pregabalin, and celecoxib (we call it “TLC” for Tylenol, Lyrica, and Celebrex) – and the use of liposomal bupivacaine in our robotic surgeries. We are now turning toward ERAS nutritional changes, most of which run counter to traditional paradigms for surgical care. And in other areas, such as dedicated preoperative counseling, we continue to refine and improve our practices.

Improved Outcomes

The ERAS mindset notably intersected gynecology with the publication in 2016 of a two-part series of guidelines for gynecology/oncology surgery from the ERAS Society. The 8-year-old society has its roots in a study group of European surgeons and others who decided to examine surgical practices and the concept of multimodal surgical care put forth in the 1990s by Henrik Kehlet, MD, PhD, then a professor at the University of Copenhagen.

The first set of recommendations addressed pre- and intraoperative care (Gynecol Oncol. 2016 Feb;140[2]:313-22), and the second set addressed postoperative care (Gynecol Oncol. 2016 Feb;140[2]:323-32). Similar evidence-based recommendations were previously written for colonic resections, rectal and pelvic surgery, and other surgical specialties.

Most of the published outcomes of enhanced recovery protocols come from colorectal surgery. As noted in the ERAS Society gynecology/oncology guidelines, the benefits include an average reduction in length of stay of 2.5 days and a decrease in complications by as much as 50%.

There is growing evidence, however, that ERAS programs are also beneficial for patients undergoing laparoscopic surgery, and outcomes from gynecology – including minimally invasive surgery – are also being reported.

For instance, a retrospective case-control study of 55 consecutive gynecologic oncology patients treated at the University of California, San Francisco, with laparoscopic or robotic surgery and an enhanced recovery pathway – and 110 historical control patients matched on the basis of age and surgery type – found significant improvements in recovery time, decreased pain despite reduced opioid use, and overall lower hospital costs (Obstet Gynecol. 2016 Jul;128[1]:138-44).

The enhanced recovery pathway included patient education, multimodal antiemetics, multimodal analgesia, and balanced fluid administration. Early catheter removal, ambulation, and feeding were also components. Analgesia included routine preoperative gabapentin, diclofenac, and acetaminophen; routine postoperative gabapentin, NSAIDs, and acetaminophen; and transversus abdominis plane blocks in 32 of the ERAS patients.

ERAS patients were significantly more likely to be discharged on day 1 (91%, compared with 60% in the control group). Opioid use decreased by 30%, and pain scores on postoperative day 1 were significantly lower.

Another study looking at the effect of enhanced recovery implementation in gynecologic surgeries at the University of Virginia, Charlottesville, (gynecologic oncology, urogynecology, and general gynecology) similarly reported benefits for vaginal and minimally invasive procedures, as well as for open procedures (Obstet Gynecol. 2016 Sep;128[3]:457-66).

In the minimally invasive group, investigators compared 324 patients before ERAS implementation with 249 patients afterward and found that the median length of stay was unchanged (1 day). However, intraoperative and postoperative opioid consumption decreased significantly and – even though actual pain scores improved only slightly – patient satisfaction scores improved markedly among post-ERAS patients. Patients gave higher marks, for instance, to questions regarding pain control (“how well your pain was controlled”) and teamwork (“staff worked together to care for you”).
