Treatment by VATS of giant bullous emphysema: results

Objective: In selected patients with giant bullous emphysema GEE and in those with specific complications, surgery may be the treatment of choice, Methods: In the period January 1993-February 1996 we performed 34 VATS treatments in 29 patients affected by GEE. There were 22 (76%) males and 7 (24%) females, with a mean age of 54 years (range 24-74). In 23 cases, a pneumothorax (PNX) was present at admission, while 6 patients were treated by choice. Altogether, we performed 23 resections of sessile bullae (type 2 of Reid) by using a linear endoscopic stapling device (Endo-path 35 and 45 mn) and 11 ligatures of pedicled bullae (type 1 of Reid) by loop (Endo-loop 'PDS'). The mean number of charges for every treatment was 8 (range 4-21). The largest bullae were perforated and deprived of incarcerated air. They were then twisted on the axis perpendicular to the base in order to improve the manoeuvrability of the lesion and favour the correct placement of the Endo-path or Endo-loop. GEE was bilateral in 7 cases: one of these was treated bilaterally in the same surgical stage, other 4 were treated by staged operations. Results: We experienced two conversions to open thoracotomy (one sessile giant bulla inside the fissura; 1 case of strong tuberculous pleural adhesions). Two patients, underwent a second operation by open thoracotomy because of a prolonged air leak. We have two peri-operative deaths, both to respiratory failure. Altogether, in 73 out of 29 (79%) cases VATS was effective and the mean hospital stay was 6 days (range 3-16). At a mean follow up of 16 months (range 1-36) no recurrence of PNX was observed. Conclusions: VATS may be considered as a suitable surgical technique to approach GEE and, in most cases, it is effective. (C) 1998 Elsevier Science B.V.
