Robotic Excision of Full-thickness Diaphragmatic Endometriosis.

STUDY OBJECTIVE

To describe a robotic approach to excision of full-thickness diaphragmatic endometriosis.

DESIGN

Surgical technique demonstration.

SETTING

Symptomatic diaphragmatic endometriosis is commonly associated with lesions that are deeply invasive. In the presence of symptomatic diaphragmatic endometriosis, the posterior diaphragm should be explored.

INTERVENTIONS

This video presents a systematic robotic approach to the excision of diaphragmatic endometriosis, highlighting key anatomic landmarks and technical considerations to complete the procedure safely and effectively. Resection of hepatic ligaments, use of a 30° endoscope, and right lateral access can be used to visualize this anatomic area [1]. The phrenic nerve is rarely identified during laparoscopy, if at all, and an inability to identify this structure during hemidiaphragm resection does not seem to result in significant patient morbidity. After diaphragm resection, the pleural cavity and lung should be systematically inspected to rule out the presence of additional endometriotic lesions. If the long axis of the diaphragmatic defect is parallel to the posterior chest wall and can be closed tension-free, then mesh is not necessary [1]. Insertion of a red rubber catheter into the thorax along with the use of negative pressure suction at the end of closure of the diaphragmatic defect may avoid use of a postoperative chest tube.

CONCLUSION

The use of robotic assistance for resection of diaphragmatic endometriosis makes this procedure easy and safe to perform. Compared with ablative procedures, complete surgical excision offers higher rates of symptom improvement and resolution in patients with diaphragmatic endometriosis.
