Clinical Trial Summary
Colon and rectal surgery is associated with high cost, long length of stay, high
postoperative surgical site infection rate, high incidence of postoperative nausea and
vomiting, and a high rate of hospital readmission. Return of bowel function is of utmost
importance in avoiding patient discomfort, morbidity, and mortality after colorectal surgery.
All patient having colorectal surgery receive neuromuscular paralysis, which is reversed at
the end of surgery with either glycopyrrolate and neostigmine, or sugammadex. Glycopyrrolate
and neostigmine both affect bowel function. Sugammadex has no effect on bowel function. The
purpose of this study is to determine if a strategy of neuromuscular reversal with
sugammadex, instead of glycopyrrolate and neostigmine, may increase gastric emptying after
surgery and lead to less postoperative complications.
Description:
Colon and rectal surgery is associated with high cost, long length of stay, high
postoperative surgical site infection rate, high incidence of postoperative nausea and
vomiting, and a high rate of hospital readmission. The 30-day mortality rate after open or
laparoscopic surgery for colorectal cancer is high-between 3 and 8%. Return of bowel function
is of utmost importance in avoiding patient discomfort, morbidity, and mortality after
colorectal surgery. The incidence of postoperative ileus after colorectal surgery has been
reported to be 10-25%. Postoperative ileus is defined as intolerance of oral intake due to a
lack of coordinated bowel motility. Significant attention has been paid to the development of
guidelines and programs to reduce the incidence of postoperative ileus and accelerate return
of bowel function after colorectal surgery.
The American Society of Colon and Rectal Surgeons (ASCRS) and the Society of American
Gastrointestinal and Endoscopic Surgeons (SAGES) created an enhanced recovery after surgery
(ERAS) protocol to promote the following outcomes in patients undergoing colorectal surgery:
"freedom from nausea, freedom from pain at rest, early return of bowel function, improved
wound healing, and early hospital discharge". An intervention that facilitates faster
postoperative gastric emptying may impact many of these outcomes; in particular, nausea may
be reduced, constipation-associated pain at rest may decline, return of bowel function would
be accelerated, and time to hospital discharge may be shortened. While administration of
medications such as Alvimopan and adjustments in anesthetic technique (providing epidural
analgesia, minimizing crystalloid administration, using multimodal analgesia) are
recommended, sugammadex is not currently considered in the ERAS protocol.
Neuromuscular paralysis is required for the duration of open and laparoscopic colorectal
surgery to decrease patient movement, improve operating conditions, and at times facilitate
ventilation. Neostigmine and glycopyrrolate are commonly used to reverse rocuronium
neuromuscular blockade at the end of surgery. Both neostigmine and glycopyrrolate impact
bowel function. Neostigmine promotes and glycopyrrolate slows gastrointestinal motility.
Co-administration of neostigmine and glycopyrrolate can have variable effects on return of
bowel function after surgery. In general, administering a higher proportion of neostigmine
than glycopyrrolate is associated with faster return of bowel function. Unopposed cholinergic
activity from neostigmine administration can cause morbidity including bradycardia,
bronchoconstriction, hypotension, urinary incontinence, and increased salivary secretions.
Thus, the ratio of neostigmine to glycopyrrolate is relatively fixed and cannot be adjusted
to promote desired gastrointestinal outcomes. Sugammadex does not bind to acetylcholine
receptors on bowel and is presumed not to affect bowel function.
Some investigations into the contribution of sugammadex versus acetylcholinesterase
inhibitors to recovery of bowel function have been completed. In retrospective studies,
sugammadex administration has been associated with faster time to first bowel movement and
less ileus-related delays in hospital discharge. Conversely, two randomized, controlled
clinical trials found no difference in outcomes related to gastrointestinal motility
including time to first flatus, time to first bowel movement, and incidence of postoperative
ileus. One randomized, controlled trial found a shorter time to first flatus, but no
difference in time to first bowel movement. Lastly, one study found a trend towards faster
gastric emptying with sugammadex. A limitation of the aforementioned prospective studies is
they include patients having surgery on their thyroid gland, gallbladder, and other
intraabdominal organs. These surgeries lack bowel handling and anastomosis, which translates
to less effect on postoperative bowel function. It is hypothesized that a randomized,
controlled trial involving patients having colorectal surgery will find faster gastric
emptying, less nausea, and less gastrointestinal complications (including ileus) when
sugammadex is administered to reverse rocuronium neuromuscular blockade, compared to
neostigmine.
The purpose of this study is to determine if administering sugammadex for reversal of
neuromuscular blockade instead of neostigmine and glycopyrrolate, a strategy that avoids
cholinergic effects on the bowel, is associated with faster gastric emptying, faster time to
achieve a TOFr > 0.9, less post-surgical gastrointestinal complications, shorter time to
first bowel movement, shorter PACU phase 1 recovery, and shorter hospital length of stay. If
sugammadex is shown to improve the aforementioned outcomes, an argument can be made that
sugammadex should be considered for inclusion in the ERAS protocol for Colorectal surgery.
