To investigate the effects of non-pneumoperitoneum laparoscopic repair-procedure ofesophageal hiatal hernia on Respiratory and Circulatory system and postoperative complication.

During March 2014 to May 2015, thirty patients from People′s Hospital of Xinjiang Uygur Autonomous Region(ASA grade I or II)scheduled for elective laparoscopic repair-procedure ofesophageal hiatal hernia, were randomly divided into group A and B with 15 cases each.Group A is non-pneumoperitoneum group, Group B is pneumoperitoneum group.After induction of anesthesia, ventilation was performed with tidal VT 10 ml/kg, respiratory rate(RR)12 breaths per minute(BPM), ratio of inspiratory to expiratory(I: E)was 1: 2.The time of 10 minutes after entering operating room as T0, The time of operation begining as T1, The time of 15 minutes after starting operation as T2 in group A, The time of 15 minutes after making Carbon dioxide pneumoperitoneum as T2 in group B, The time of skin staple or relieve pnellmoperitoneum as T3.To collect blood for laboratory examination at T0, T1, T2, T3 respectively, and record vital sign.

Compared with group A, Group B have lower PaO₂ and higher end-tidal pressure of carbon dioxide and peak pressure of airway(P<0.05). The incidence of shonlder soreness and cut pain was lower in group A(P<0.05).

Compared with pneumoperitoneum laparoscopic repair-procedure ofesophageal hiatal hernia, non-pneumoperitoneum laparoscopic repair-procedure ofesophageal hiatal hernia maintained a steady circulation which more conduciveto the oxygenation.And the recovery of gastrointestinal tract functions were faster.
