Study on functional cardiorespiratory changes after laparoscopic Nissen fundoplication

purpose: to analyze the behavior of cardiopulmonary function in postoperative of laparoscopic nissen fundoplication. methods: thirty-two patients, 13 males (41%) and 19 females (59%), were evaluated. their age ranged from 25 to 67 years, with a mean of 44.4 ± 10.9. pulmonary volumes, respiratory pressures and exercise tests were performed in the preoperative period (pre) and in the first (po1), second (po2), fifth (po5) and thirtieth (po30) postoperative periods. results: thirty-two patients were evaluated, of whom 59% were females. mean age was 44.4 ± 10.9 years. lung volumes had significant decrease at po1 and po2 and were similar to pre values at po5. respiratory pressures were altered only at po1. the distance covered in the 6-minute walk test had significant reduction until po2, and climbing time in the stair-climbing test significantly increased at po2. conclusion: patients submitted to lnf surgery have decreased cardiorespiratory function in the early postoperative period; however, they soon return to preoperative conditions.
