Background and Purpose. At many institutes, patients with moderate to severe spontaneous pneumothorax (SP) are treated with continuous chest drainage under hospitalization. However, many of these patients are young, and they often opt for outpatient treatment. We evaluated the effectiveness of and indications for Thoracic Egg® (TE) (Sumitomo Bakelite Company Limited, Tokyo, Japan), a portable thoracic drainage device for SP. Between June 2005 and December 2009, we used TE to shorten the hospitalization period for SP treatment at our hospital. Patients and Methods. We examined 57 patients (44 men and 13 women; age range, 14-75 years; mean age, 29.5 years), 36 of whom had primary and 21 had recurrent pneumothorax. TEs were attached to patients who had moderate to severe SP. Patients with tension pneumothorax, hydropneumothorax, hemopneumothorax, or pulmonary emphysema were excluded. Results. Of the 57 patients, 28 were treated as outpatients with TE only, and 29 underwent surgery for persistent air leakage or recurrent pneumothorax. The total drainage period with TE was 307 days, and the total hospitalization period for the pneumothorax operations was 163 days. No complications occurred in any except one patient who required replacement with a larger bore trocar catheter and needed continuous suction under hospitalization. The total period of outpatient therapy with TE was 128 days, and the total period of outpatient drainage with TE for those who required surgery before admission was 137 days. From these results, we suggest that patients can be followed-up as outpatients, and the hospitalization period can be shortened by 86.3% on performing outpatient therapy with TE instead of chest drainage under hospitalization. Conclusion. For outpatient treatment of SP, TE is effective and can shorten the hospitalization period for appropriately selected patients.
