Hepatectomy is widely used to treat patients with hepatocellular carcinoma (HCC), even those with intermediate and advanced disease. Despite its well-demonstrated clinical safety and efficacy in many patients, it is associated with postoperative morbidity and mortality. One complication after hepatectomy is delayed resumption of gastrointestinal function, known as postoperative ileus. This can decrease patient comfort and increase morbidity and mortality, prolonging hospital stay and raising healthcare costs. While postoperative ileus usually resolves within approximately 3 days, it can last longer in some cases as a condition termed postoperative paralytic ileus. Postoperative use of opioid-based analgesics can increase incidence of postoperative ileus. No drugs or interventions to prevent or treat postoperative ileus have been approved by the China Drug Administration or the US Food and Drug Administration. Several studies show that chewing gum, a new and simple modality, can accelerate complication-free recovery of gastrointestinal function following gastrointestinal surgery and obstetrical-gynecological surgery. This raises the question whether postoperative smoked plum, or chewing gum can reduce risk of postoperative ileus following hepatectomy. To examine this question, we conducted a randomized controlled trial to compare incidence of postoperative ileus and length of hospital stay in HCC patients who received smoked plum, chewing gum or no intervention following hepatectomy.
