Post-cholecystectomy syndrome in pediatric patients: Occurrence and spectrum of symptoms.

BACKGROUND: Post-cholecystectomy syndrome (PCS) refers to persistent or new abdominal symptoms after cholecystectomy. As there are very few reports on PCS in pediatric patients, we aimed to examine whether it was a frequent finding and which symptoms the affected children experienced.

METHOD: This is a retrospective cross sectional study of pediatric patients, who underwent cholecystectomy during 2003-2019 at Oslo University Hospital. The PedsQL™ gastrointestinal symptoms scale questionnaire and a self-designed questionnaire exploring satisfaction after surgery and current medical conditions were mailed to all eligible patients. Patient/parental consent and approval from the local data protection officer (19/09054) were obtained.

RESULTS: Questionnaires were sent to 82 patients of whom 44 (54%) answered. There were no significant demographic differences between the responders and the non responders. We identified 16 (36.7%) patients to have PCS. The most common symptoms were diarrhea (25%), bloating (16%), and heartburn/reflux (16%). Overweight was more common in patients with PCS (31%) than in patients without PCS (4%) (p = 0.014). Altogether 34/44 (77.3%) patients were satisfied with the result of the cholecystectomy; 92,6% of patients without PCS and 56.6% of those with PCS (p = 0.012).

CONCLUSION: PCS is not uncommon in pediatric patients, and they report a wide range of gastrointestinal symptoms. We identified overweight as a potential risk factor for developing PCS. Nonetheless, most patients got total relief of abdominal pain and were satisfied with outcome after cholecystectomy.
