Brief Summary

Chronic abdominal and pelvic pain is a common complaint following peritoneal surgery, affecting 20-40% of patients. Adhesions account for 60% of chronic postoperative pain cases, suggesting that adhesiolysis can play an important role in the management of such pain. Despite initial promising results regarding the effect of adhesiolysis on post-operative pain, implementation of the procedure has been challenging. The major problems associated with adhesiolysis for pain are recurrence of pain, need for invasive diagnosis with high rates of 'negative' laparoscopies, and inadvertent bowel injury during surgery. However, diagnosis and treatment of adhesions may be improved through the use of novel cine-MRI techniques, and with application of anti-adhesion barriers following adhesiolysis. In this study the investigators evaluate a new practice-based approach to the problem of chronic post-operative pain caused by adhesions. This practice-based approach includes use of a novel imaging technique for adhesions (cine-MRI) and shared decision making. Cine-MRI holds promise to diagnose and map adhesions. Thus patients with no adhesions, or high risk for bowel injury, can be waived from surgical treatment. By using anti-adhesion barriers the investigators attempt to prevent adhesion reformation and improve long-term outcomes of adhesiolysis.

Outcome Measures

Primary Outcomes (1)

  • Change in pain

    measured by a verbal rating pain change scale (VRCS)

    long-term >6 months to 3 years following surgery or cineMRI

Secondary Outcomes (5)

  • Current pain

    long-term >6 months to 3 years following surgery or cineMRI

  • Frequency of pain

    long-term >6 months to 3 years following surgery or cineMRI

  • Daily discomfort

    long-term >6 months to 3 years following surgery or cineMRI

  • Healthcare utilization

    long-term >6 months to 3 years following surgery or cineMRI

  • Complications of surgery/ adhesiolysis

    Peri-operative (up to 30 days after adhesiolysis)

Study Arms (3)

Group 1: adhesiolysis

Group 1 (the operative group) consisted of all patients who underwent laparoscopy and/or laparotomy. Typically patients had positive cine-MRI. A few patients with inconclusive cine-MRI who underwent diagnostic laparoscopy are also included in this group. Patients with no adhesions found during operation remain in group 1, because analysis is performed on intention-to-treat basis.

Procedure: Adhesiolysis

Group 2: Adhesions, conservative

Patients with evidence of adhesions based on cine-MRI who did not undergo laparoscopy or laparotomy.

Group 3: No adhesions

Patients in whom no evidence of adhesions was found on cine-MRI, and who did not undergo laparoscopy or laparotomy .

Interventions

AdhesiolysisPROCEDURE

Diagnostic laparoscopy or laparotomy with lysis of adhesions.

Group 1: adhesiolysis
