Role of Preoperative Dexamethasone Nebulization in Reducing Bougie Complications Encountered After Sleeve Gastrectomy: a Prospective Double-Blind Control Interventional Study.

Abstract

The usage of bougie devices in guiding the extent of sleeve gastrectomies has been associated with several laryngeal and pharyngeal complications. Despite these being distressing for patients, they draw little attention in current literature. To study the role of preoperative nebulized dexamethasone in relieving the symptoms related to bougie insertion during laparoscopic sleeve gastrectomy postoperatively. A prospective interventional study that included 80 patients. The patients were assigned to two groups, 40 patients in each group: the dexamethasone group (D) which received nebulized dexamethasone 8 mg 1 h before surgery and the control group (S) which received saline nebulizer instead. Assessment of postoperative sore throat, nausea and vomiting, odynophagia, and change of voice was used as an outcome comparative tool. The patient's age ranged from 17 to 61 years, and the mean age of patients was 34.51 (± 9.5) years. Patients were composed of 13 (16.3%) males and 67 (83.8%) females. The study found a significant preference of outcome values in the dexamethasone group. Sore throat mean and medians were less at all-time intervals: 0 h (p < 0.001), 1 h (p < 0.001), 6 h (p < 0.004), and 24 h (p < 0.001). Nineteen patients of the saline group suffered from a change of voice (p < 0.001), compared to only 4 patients in the dexamethasone group. On the contrary, no significant differences are noted in the incidences of PONV and odynophagia. Preoperative nebulized dexamethasone was found to be an effective measure in reducing bougie insertion complications in laparoscopic sleeve gastrectomy.
