چکیده (انگلیسی):

Background: Diaphragm plication surgery is conducted to remove dyspnea, which results from mediastinal shift, atelectasia, and ventilation/perfusion dyssynchrony in lungs that occur because of an eventrated diaphragm. This study aims to determine whether diaphragm plication has any effect on respiration by analyzing the patients’ changing values in the respiratory function test (RFT) after plication surgery. Methods: Sixteen patients who underwent diaphragm plication surgery in our clinic because of plication eventration or paralysis were examined prospectively. Diaphragm eventration values were assessed using a calculation method that uses posteroanterior pulmonary radiographies taken during patient admission and control; then, these data were recorded. The amount of changes in the eventration levels and in restrictive respiratory failure parametersdforced expiratory volume in 1 second (FEV1), forced vital capacity (FVC) of RFTsdconducted in pre- and postoperative control periods were compared using statistical analysis methods. The compatibility between the amounts of RFT changes was examined through a satisfaction surveydusing a questionnaire that consisted of multiple choice questions with answer options such as “better,” “the same,” and “worse”dto understand preoperative and postoperative symptom levels in the 12th month of postoperative control. Results: According to postoperative levels, a decrease between 19% and 23% was observed in eventration amounts within the 1st postoperative month, 6th postoperative month, and 12th postoperative month. In addition, the highest average increase in FEV1 liter (lt) values was 0.2 lt and 0.25 in FVC (lt) values. Conclusion: Researchers of this study believe that more distinctive decisions need to be taken while identifying patients for surgery in unilateral diaphragm eventrations, especially in the adult patient group; surgical option should be used for cases in which the eventrated diaphragm results in mediastinal shift and respiratory failure.
