[Laparoscopy in chronic abdominal pain in children]

The recurrent chronic abdominal pain (RAP) is one of the most usual pathologies in pediatrics. It may appear in the form of periodical or continuous sharp crisis. In order to be accepted as chronic, the presence of this pain must last at least 3 months. In many of the reference publications, only between 5 and 1% of the cases are considered to have an organic ethiology and the rest are labelled as functional processes of psychological origin. The reason for our communication is to show our experience on 304 RAP patients from 1995 to 2001. We also want to highlight the usefulness of laparoscopy in order to diagnose and treat 14.45% (44) of cases of this group of patients.

304 patients between 5 and 14 years old were studied from 1995 to 2001. We followed a protocol of: medical and personal medical record, specific anamnesis for RAP, detailed description of the diet and intestinal habits, physical exploration. Laboratory: 1) blood analysis, hepatic profile, glucose, cholesterol, creatinine, amylase, 2) urine sediment and may be urine culture, 3) faeces analysis and 4) vaginal flow analysis. Image diagnosis is: simple abdomen radiography, ultrasonography and intestinal Rx. Guided and specific determinations: spired urea test, gastric chemism, lactose test, gastroscopy and biopsy, colonoscopy and biopsy, laparoscopy.

In short, we can say: 74 patients (23.4%) come with inappropiate feeding diets, 31 (10.1%) with helicobacter pilori, 20 (6.5%) with adenoids, pharynx and pharyngeal processes, the same figure from gynaecologic origin, 18 (5.9%) from psychological origin, and in 44 cases (14.45%) laparoscopy was indicated.

The anatomopathological study in the cases in which we carried out laparoscopic appendicectomy does not allow us to accept the symptoms of chronic appendicitis. The exploratory laparoscopy and the appendectomy have meant benefits for the solution to this pathology in 14.45% of patients. It is essential to carry out a long-term follow-up, at least 12 months, to be sure RAP is cured. We must carry on looking for aetiological cause of RAP.
