Pilot clinical study on the prevention of complications after lung biopsy by the MIPP kit PNX device

Transl Cancer Res. 2022 Dec;11(12):4338-4348. doi: 10.21037/tcr-22-1203.


BACKGROUND: Pneumothorax (PNX), pulmonary hemorrhage, hemothorax and chest wall hematoma are the most commonly reported complications of percutaneous lung biopsy (PLB). Sealing the biopsy tract with different types of materials is an emerging way to prevent PLB complications.

METHODS: To investigate the safety and efficacy of a new device, Minimally Invasive Percutaneous Procedure Kit for Pneumothorax (MIPP-Kit PNX), when used in association with a resorbable bio-compatible glue in the prevention of PLB complications. A prospective, multicenter, open-label, single-arm study was performed to evaluate the complication rate after glue administration by the new investigational device during PLBs.

RESULTS: Fourty-three patients were enrolled after informed consent signature (40 underwent PLB, while three were screening failures). Only 3 patients (7.5%, 95% CI: 0.0-15.7%) developed complications within 48 h after glue injection during PLB: two developed minor pneumothoraces and one a pulmonary hemorrhage. No patients who showed procedural complications before glue administration were reported with any recurrent or new complications after glue administration.

CONCLUSIONS: In comparison with the data reported in the literature, this trial results support the safe and effective use of the MIPP kit PNX in the prevention of PLB complications. These promising preliminary results warrant further confirmation in larger clinical trials.

TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT04071509.
