Diaphragmatic surgery combined with pleurodesis and hormonal therapy significantly reduced recurrence rates in catamenial pneumothorax compared to pleurodesis alone.

This single-center retrospective cohort study examined 24 women who underwent surgery for pneumothorax due to diaphragmatic endometriosis, comparing recurrence after pleurodesis alone versus diaphragmatic surgery plus pleurodesis from 2008–2016. All patients had diaphragmatic abnormalities, with pleurodesis-alone involving brown/violet spots in all and diaphragmatic surgery involving perforations in all, and only one VATS conversion occurred in the diaphragmatic-surgery group; the pleurodesis-alone group had recurrence in all cases (100%) versus 12.5% after diaphragmatic surgery plus pleurodesis. The authors note between-group differences in BMI and smoking habits, which may confound outcomes. This paper is centrally about endometriosis — specifically diaphragmatic endometriosis causing catamenial pneumothorax and the role of diaphragmatic surgery, pleurodesis, and postoperative hormonal therapy in preventing recurrence.

Abstract

Background Catamenial pneumothorax (CP) is defined as a recurrent, spontaneous pneumothorax occurring within a day before or 72 h after the onset of menstruation. Most first episodes go undiagnosed and treated as primary spontaneous pneumothorax, and only after recurrence is the clinical suspicion of CP raised. No gold-standard management approach exists, especially in terms of managing diaphragmatic involvement.

Methods

This study is a single-centre cohort retrospective study of 24 female patients who underwent surgery for pneumothorax due to diaphragmatic endometriosis between January 2008 and December 2016. Two groups were compared: a group that underwent pleurodesis alone (8 patients) and a group that underwent diaphragmatic surgery and pleurodesis (16 patients).

Results

There were differences in BMI and smoking habits between the two groups. The right diaphragm was involved more often (6vs15, p = 0.190). VATS was the preferred surgical approach and only one conversion occurred in the diaphragmatic surgery group (p = 0.470). Diaphragmatic abnormalities were present in all the patients, brown/violet spots (100%) in the pleurodesis group and perforations (100%) in the diaphragmatic surgery group (p < 0.001). There were no differences in days of chest tube removal and length of stay. The recurrence rate was 100% in the pleurodesis alone group while it was only 12.5% in the diaphragmatic surgery group (< 0.001).

Conclusions

In our experience, diaphragmatic surgery and pleurodesis followed by hormonal therapy was an effective approach in preventing recurrence in patients with catamenial pneumothorax and diaphragmatic involvement. Similar content being viewed by others
