Effect of Lollipop on Postoperative Gastrointestinal Recovery in Children

Ileus Postoperative

Postoperative ileus is common in children. There are various method to prevent postoperative ileus. In this study, the investigators will explore the role of sucking lollipop after operation on the recovery of gastrointestinal function in children.

Postoperative ileus is a common occurrence among children undergoing major operations, including gastrointestinal and spinal surgeries. It can result in physical discomfort, extended hospital stays, delayed resumption of activity and poor satisfaction with surgical care. The pathophysiology and course of postoperative ileus occurs in three phases: increased sympathetic activity, release of inflammatory mediators and vagal activation as ileus resolves. Multiple risk factors of postoperative ileus have been identified in various studies, including general risk factors such as significant blood loss, male gender and medical comorbidities like chronic obstructive pulmonary disease (COPD), as well as risk factors specific to the surgery, such as the laparotomy approach, emergency surgery and stoma formation. Chewing gum, as a form of sham feeding, has been employed in adults and children as a modality to decrease risk of postoperative ileus. There has been concrete evidence that it could result in expedited recovery of gastrointestinal function after surgery in adult populations. However, it may not be a feasible option for infants and young children. Lollipop, on the other hand, is easier to apply in children which only require the action of sucking. It can stimulate the cephalic phase of digestion via vagal cholinergic stimulation and release of gastrointestinal hormone (gastrin and motilin) through its taste and absorption of sugar. The current evidence of lollipop in the recovery of postoperative gastrointestinal function in children is limited with only two randomised controlled trial published so far with satisfactory outcomes, yet both were not indexed and were not carried out in accordance with Consolidated Standards of Reporting Trials (CONSORT). Based on these reasons, the investigators plan to carry out a prospective, multiple-centred, non-blinded, randomized controlled trial using a parallel arm design on the effect of lollipop on recovery of gastrointestinal function after operation in children. Children recruited will be randomly assigned into either lollipop group or non-treatment group; lollipop will be given to children in treatment group after operation. Their outcomes will be compared.
