More about adhesions and postoperative pain

In November 2016, I wrote about adhesions and whether they are the cause of chronic abdominal pain. I and several surgeons who commented felt they weren't.

Some new information from the February 2017 issue of the journal Surgery is just in. A randomized, double blind, placebo-controlled trial from The Netherlands was originally published in 2003 after one year of follow-up. At that time, there was no apparent benefit from an operation to lyse [divide] all adhesions laparoscopically in 52 patients compared to a placebo operation that involved performing only laparoscopy to assess the extent of adhesions in 48.

The current paper looked at outcomes 12 years after the original surgery was done. Follow-up was available for 73% of the patients—42 in the group who had adhesiolysis and 31 who had laparoscopy only.

The authors concluded, “Laparoscopic adhesiolysis was less beneficial than laparoscopy alone in the long term. Secondly, there appeared to be a powerful, long-lasting placebo effect of laparoscopy. Because adhesiolysis is associated with an increased risk of operative complications, avoiding this treatment may result in less morbidity and health care costs.”

Unfortunately the paper has a few flaws.

Do postoperative adhesions cause abdominal pain?

A reader asks whether I think adhesions cause postoperative abdominal pain and if so, how should they be treated?

I have always been skeptical (no surprise) about blaming adhesions for pain.

If adhesions cause abdominal or pelvic pain, what is the mechanism? We know that the intestine can be handled, cut, and cauterized without causing pain. What about tugging or pulling on the bowel? Would that cause pain? I doubt it. How much tugging or pulling can take place within the confines of the peritoneal cavity anyway? A literature search did not turn up any studies on  the mechanism of adhesions causing pain.

UpToDate, the online medical textbook, has a section on this topic. It doesn't address how adhesions cause pain but does discuss the evidence that reoperating on patients with adhesions is not worthwhile.
