Prophylactic Oral Antibiotics on Sinonasal Outcomes Following Endoscopic Transsphenoidal Surgery for Pituitary Lesions

Официальное название

A Multicenter, Randomized, Placebo-Controlled, Double-Blind Study Evaluating the Impact of Prophylactic Oral Antibiotics on Sinonasal Outcomes Following Endoscopic Transsphenoidal Surgery for Pituitary Lesions

Обзор

To find out whether oral antibiotics given after transsphenoidal endoscopic surgery for pituitary adenoma improves sinus and nasal symptoms, reduces the incidence of infection (sinusitis), and helps mucosal healing in the nasal passages.

Подробное описание

Transsphenoidal surgery is the standard of care for most symptomatic pituitary adenomas. Since transsphenoidal surgery exploits the nasal passage to reach the sella turcica and pituitary gland, the technique causes disruption of sinonasal function and temporarily impacts sinonasal quality of life. Disrupted sinonasal function is a primary source of postoperative morbidity following transsphenoidal surgery. Common sinonasal complications include sinusitis, synechiae formation, nasal obstruction and crusting. The development of postoperative sinusitis is specifically associated with decreased sinonasal function after surgery. Because the nasal cavity is a contaminated surgical field, practitioners routinely prescribe a course of oral postoperative antibiotics for 7-14 days (in addition to standard prophylactic perioperative intravenous antibiotics) with the intention of improving nasal functional outcomes. To date, no studies have examined whether the administration of oral antibiotics following transsphenoidal surgery improves sinonasal healing. This question has been studied in a closely-related field, functional endoscopic sinus surgery (FESS). A meta-analysis of clinical trial data obtained in FESS indicated that current literature does not support the use of oral antibiotics to reduce infection, improve symptoms scores, or improve endoscopic findings. Furthermore, there is the potential for antibiotic-related adverse events including the emergence of bacterial resistance, Clostridium difficile infection, and allergic reactions to the medication. Despite the lack of supporting evidence in FESS, prophylactic antibiotic use for improving sinonasal healing is still common in pituitary surgery. The investigators propose to study whether prophylactic oral antibiotics following transsphenoidal surgery improve sinonasal quality of life, reduce sinusitis incidence, and promote mucosal healing following endoscopic transsphenoidal surgery.

Вмешательства

• Препарат Placebo
  PO BID placebo for 7 days. Postoperative days 1 through 7: patients will administer saline spray (e.g., Ocean nasal spray) to both nostrils four times daily. Postoperative days 8 through 30: patients will begin twice daily sinus irrigation rinse (e.g., Neti-pot) until day 30. After day 30, patients will perform sinus irrigation as needed. If a patient is unable to tolerate nasal rinses, saline spray can be used as an alternative.
• Препарат Oral Antibiotics cefdinir or trimethoprim/sulfamethoxazole
  Oral antibiotics (cefdinir \[Omnicef®\] 300 mg PO BID or trimethoprim/sulfamethoxazole \[Bactrim DS™\] PO BID for cephalosporin intolerant patients) for 7 days.Postoperative days 1 through 7: patients will administer saline spray (e.g., Ocean nasal spray) to both nostrils four times daily. Postoperative days 8 through 30: patients will begin twice daily sinus irrigation rinse (e.g., Neti-pot) until day 30. After day 30, patients will perform sinus irrigation as needed.
