  2. Functional Abdominal Pain • Chronic pain disorder that is not explainable by a structural or metabolic disorder by using currently available diagnostic methods • Commonly associated with other somatic symptoms, including chronic pain of GYN/GU systems, fibromyalgia, migraines. • Psychological disturbances are more likely when pain is persistent over a long period of time • In psychiatry, functional abd pain would satisfy a pain criterion toward the diagnosis of a somatization d/o • Frequently associated with other psychosocial conditions (anxiety, depression, h/o trauma/abuse) • Such trauma increases awareness of bodily sensations, although visceral pain thresholds are not reduced

  3. Rome Criteria for Diagnosis 1. Continuous or nearly continuous abdominal pain 2. No or only occasional relationship of pain with physiological events (eg, eating, defecation, or menses) 3. Some loss of daily functioning 4. The pain is not feigned (eg, malingering) 5. Insufficient symptoms to meet criteria for another functional gastrointestinal disorder that would explain the pain * Criteria fulfilled for the last 3 months with symptom onset at least 6 months before diagnosis

  4. How common is it? • Hard to say given limited available data • Less common than other FGIDs • Reported prevalence in North America range from 0.5% to 2% and do not differ from those reported in other countries. • More common in women (female: male 3:2) • Prevalence peaks in the fourth decade • Patients with this have high work absenteeism and health care utilization and, thus, impose a significant economic burden

  5. Associated features • Expressing pain of varying intensity through verbal and nonverbal methods. may diminish when the patient is engaged in distracting activities, but increase when discussing a psychologically distressing issue or during examination • Urgent reporting of intense symptoms disproportionate to available clinical and laboratory data (eg, always rating the pain as “10” • Minimizing or denying a role for psychosocial contributors, or of evident anxiety or depression • Requesting diagnostic studies or even exploratory surgery to validate the condition as “organic” • Focusing attention on complete relief of symptoms rather than adaptation to a chronic disorder • Seeking health care frequently • Taking limited personal responsibility for self-management, while placing high expectations on the physician to achieve symptom relief • Making requests for narcotic analgesics when other treatment options have been implemented

  6. Clinical Evaluation • Clinical/psychosocial assessment • Observation of associated features mentioned above • Detailed physical exam

  7. Psychosocial Assessment 1. What is the patient’s life history of illness? 2. Why is the patient presenting now for medical care? 3. Is there a history of traumatic life events? 4. What is the patient’s understanding of the illness? 5. What is the impact of the pain on activities and quality of life? 6. Is there an associated psychiatric diagnosis? 7. What is the role of family or culture? 8. What are the patient’s psychosocial impairments and resources?

  8. Treatment • Establish an effective patient-physician relationship (empathy, pt education, validate the illness, reassurance, treatment negotiation, establishment of reasonable limits in time/effort) • Follow a general treatment approach (setting goals, help pt. take responsibility, base treatment on sx severity/degree of disability, referral to mental health if warranted, multidisiplinary pain tx center in those with refractory sx) • Offer more specific management that often encompasses a combination of medical options

  9. Psychological Tx • Cognitive behavioral therapy • Dynamic or interpersonal psychotherapy • Hypnotherapy • Stress management • Although these improve mood/coping/QOL, do not impact somatic/visceral sx • Therefore best used in combination with medical management

  10. Medications • TCAs (imipramine, desipramine, amitryptilline) • SNRIs (venlafaxine and duloxetine) • Anticonvulsants (gabapentin, carbamazepine, • and lamotrigine) • NSAIDs offer limited benefit • Narcotics should be avoided (risk of abuse/NBS)

  11. Complementary Therapies • Spinal manipulation/massage and acupuncture are commonly used in pts w/ chronic pain disorders, but supporting data is limited • A blinded, randomized trial of 100 patients undergoing either laparoscopic adhesiolysisor diagnostic laparoscopy alone found no advantage to adhesiolysis. • This study also reported a significant improvement in chronic abdominal pain over 6 months whether laparoscopy alone or laparoscopic adhesiolysis were performed, suggesting spontaneous improvement in these patients over time.
