Ex vivo and in vivo evaluation of transsphenoidal Liqoseal application to prevent cerebrospinal fluid leakage.

Background: Despite improvements in closure techniques by using a vital nasoseptal flap, the use of sealing materials, and improved neurosurgical techniques, cerebrospinal fluid (CSF) leak after transsphenoidal surgery still is a clinically relevant problem. Liqoseal® (Polyganics bv, Groningen, The Netherlands) is a CE-approved bioresorbable sealant patch for use as an adjunct to standard methods of cranial dural closure to prevent CSF leakage. This study aims to evaluate the application of Liqoseal in transsphenoidal surgery ex vivo and in vivo.

Five-Year Outcome of Laparoscopic Fundoplication in Pediatric GERD Patients: a Multicenter, Prospective Cohort Study.

Background: Gastroesophageal reflux disease (GERD) is a common disease in children. When drug treatment fails, laparoscopic anti-reflux surgery (LARS) is considered. Short-term follow-up studies report high success rates; however, few studies report long-term results.
