Differential advantage of liver retraction methods in laparoscopic fundoplication for neurologically impaired patients: a comparison of three kinds of procedures

Aim of the study Liver retraction during laparoscopic fundoplication is important for obtaining an optimal space. Several methods have been developed, but the risks and benefits are unclear. We compared three different approaches and evaluated their safety and utility. Methods Forty-three neurologically impaired patients who underwent laparoscopic fundoplication between 2005 and 2018 were classified into three groups: A, snake retractor method, n = 18; B, crural suture method, n = 13; C, needle grasper method, n = 12. Patients’ characteristics and outcomes were reviewed. Main results The liver retraction time was significantly shorter in group C than in A or B ( p
