Abstract

Background: Diaphragmatic herniorraphy is the treatment of choice for traumatic diaphragmatic hernia (TDH). Several
methods have been described for the removal of residual air and fluid during and after surgery, such as the insertion of
chest drains, intercostal thoracentesis, and transdiaphragmatic thoracentesis. However, there are no indications  regarding the most useful technique and the impact that choice of technique could have in the immediate postoperative period.


Aim: To evaluate the development of complications and outcomes associated with the use of intraoperative transdiaphragmatic thoracentesis in cats undergoing diaphragmatic herniorrhaphy for TDH.


Methods: Medical records  of cats treated for acute and chronic TDH between 2010 and 2019 were reviewed. Cats were included if intraoperative  pneumothorax was treated with transdiaphragmatic thoracentesis, without the use of intercostal chest drain. Outcome,  intra- and post-operative complications were recorded.


Results: Intraoperative and postoperative complication rates  were 3.3% and 12.4%, respectively. Development of postoperative pneumothorax was associated with the presence of  comorbidities (p = 0.046). The overall survival rate was 93.3%. Long-term survival had a significant association with the  presence of comorbidities (p = 0.045), if the procedure was performed as an emergency (p = 0.041) or in older cats (p =  0.011).


Conclusion: Intraoperative transdiaphragmatic thoracentesis could be considered an effective method for the  removal of residual air after surgery for TDH, because it ensures a good outcome for the patient, with low development  of complications, especially for uncomplicated cases. The presence of comorbidities, the need to perform a surgical procedure in emergency, and the age of the patient can be considered factors influencing the development of complications. Critical patient selection, based on assessment of potential risk factors for complications is warranted to  understand which patient will benefit from thoracostomy tube placement.
