Resumen

Introduction and aim: Functional abdominal pain (FAP) is one of the major astrointestinal complaints in childhood. Studies have reported occult constipation (OC) as one of the leading causes of abdominal pain. Recent researches have proposed laxatives as potent therapeutic targets for abdominal pain in patients with OC. However, no study has compared effect of poly ethylene glycol (PEG) and lactulose on occult constipation. Materials and methods: 51 patients aged 4 to 18 years with abdominal pain who had OC (defined as fecal impaction in abdominal X ray) were studied. Demographic and clinical data including age, sex, body weight, height, abdominal pain duration, abdominal pain rate and fecal odor were registered. They were randomly assigned to receive PEG (1gr/kg) or Lactulose (1cc/kg) for at least two weeks. All patients were reevaluated by pain measurement scale after at least two weeks of treatment. Results: It is indicated that the efficacy of PEG for reducing abdominal pain in OC was 48% while it was 37% for Lactulose. This study indicated that this efficacy is not affected significantly by sex and fecal odor, however this efficacy is influenced by age, body weight, abdominal pain duration and abdominal pain rate for both PEG and Lactulose. Conclusion: It could be concluded that PEG is a more efficient drug for treating abdominal pain in occult constipation than Lactulose and its optimum effect can be achieved in elder patients with more severe abdominal pain.

have reported occult constipation (OC) as one of the leading causes of abdominal pain. Recent researches have proposed

laxatives as potent therapeutic targets for abdominal pain in patients with OC. However, no study has compared effect of

poly ethylene glycol (PEG) and lactulose on occult constipation. Materials and methods: 51 patients aged 4 to 18 years with

abdominal pain who had OC (defined as fecal impaction in abdominal X ray) were studied. Demographic and clinical data

including age, sex, body weight, height, abdominal pain duration, abdominal pain rate and fecal odor were registered. They

were randomly assigned to receive PEG (1gr/kg) or Lactulose (1cc/kg) for at least two weeks. All patients were reevaluated by pain

measurement scale after at least two weeks of treatment. Results: It is indicated that the efficacy of PEG for reducing abdominal

pain in OC was 48% while it was 37% for Lactulose. This study indicated that this efficacy is not affected significantly by sex and

fecal odor, however this efficacy is influenced by age, body weight, abdominal pain duration and abdominal pain rate for both

PEG and Lactulose. Conclusion: It could be concluded that PEG is a more efficient drug for treating abdominal pain in occult

constipation than Lactulose and its optimum effect can be achieved in elder patients with more severe abdominal pain.
