Brief Summary

Chronic abdominal pain is highly prevalent in patients undergoing abdominal surgery. Adhesions are reported to be one of the most common causes of chronic pain after surgery. There is little epidemiological data on the natural course and risk factors of pain. In this study the investigators will assess risk factors for chronic pain and natural course by tracking pain scores through an app in a cohort of 1,500 patients undergoing abdominal surgery. In part two of the study patients with persistent abdominal pain at 12 months, that meet IASP criteria for chronic pain will have clinical investigations to determine the cause of their pain. This investigation includes cineMRI for diagnosis and mapping of adhesions.

Outcome Measures

Primary Outcomes (2)

  • Risk factors for development of chronic pain

    Prediction model for development of chronic post-operative abdominal pain, assessed using a dynamic prediction model. Potential factors are taken from baseline measurements, and the repeated measurements of the course of pain.

    12 months

  • Incidence of adhesions on cineMRI in patients with chronic abdominal pain.

    Primary outcome of the second phase of study in which patients with chronic pain will undergo clinical investigations determining the cause of their pain,

    2 months

Secondary Outcomes (6)

  • incidence of chronic pain

    12 months

  • Duration of moderate to severe pain

    60 days post surgery

  • Health-related quality of life

    12 months

  • Return to daily activity/ work

    12 months

  • Healthcare utilization

Study Arms (1)

Patients undergoing abdominal surgery

All adult patients undergoing elective abdominal surgery are eligible. Abdominal surgery includes each operation in which the peritoneal cavity is openen, i.e. laparotomy or laparoscopy.

Other: Pain tracking app

Interventions

In this study no clinical interventions are made. Patients scheduled for surgery will be treated according to the standard of care. All patients enrolled will have an application installed to track their pain symptoms through short daily and weekly questionnaires.

Sampling MethodNon-Probability Sample
Study Population

Patients with undergoing different types of abdominal surgery (laparotomy and laparoscopy). Included are all patients undergoing elective surgery. Patients undergoing laparoscopic cholecystectomy and caesarean section are excluded because both are very frequent procedures with a low risk of chronic post-operative pain and low risk of adhesions. These procedure could therefore significantly impact the power of the study. Although patients after laparoscopic cholecystectomy frequently report pain, these pain symptoms are often attributable to persistence of pre-existing pain. There are known difficulties in differential diagnosis of symptomatic cholelithiasis and dyspepsia, that might interfere with indication for cholecystectomy

You may qualify if:

  • Patients who developed chronic post-operative abdominal pain according to IASP criteria:
  • Daily pain in the past three months
  • Pain is continues or intermittent
  • Pain scores for the worst pain are 4 or higher
  • Or patients without chronic pain (n=100) who are propensity matched for type of surgery and risk factors for developing chronic pain.

You may not qualify if:

  • A potential subject who meets any of the following criteria will be excluded from participation in this study:
  • Mental incompetence
  • Planned for laparoscopic cholecystectomy
  • Planned for Caesarean section
  • Contra-indications for MRI (without contrast) including:
  • Severe claustrophobia
  • Metal splinters in eyes
  • Cerebral vascular clips
  • Electronic medical implants
  • Patients who do not want to be informed about potential incidental findings of MRI-scan
