Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a prospective study to assess the yield of pleural biopsy obtained with the routine flexible thoracoscopic biopsy forceps versus that obtained with a flexible cryoprobe during semirigid thoracoscopy

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Consecutive patients with exudative pleural effusions who are planned to undergo semirigid thoracoscopy will be enrolled in the study if they satisfy the inclusion criteria. They will be randomized in 1:1 ratio using a computer-generated randomization sequence to the following groups:

Group A: Four pleural biopsy specimens obtained using the flexible cryoprobe followed by eight pleural biopsy specimens obtained using the flexible thoracoscopic forceps OR Group B: The above two procedures will be performed in the reverse order The biopsies will be performed from different areas of the involved pleura with the two techniques. Thoracoscopy will be performed in the bronchoscopy suite on spontaneously breathing subjects (fasting for 8 h) under conscious sedation (using midazolam, pentazocine, and tramadol) observing complete aseptic precautions.

Cryobiopsy

Pleural biopsy with a flexible cryoprobe

Group Type ACTIVE_COMPARATOR

Cryoprobe pleural biopsy first

Intervention Type DEVICE

Four pleural biopsy specimens will be obtained using the flexible cryoprobe (ERBOCRYOCA, ERBE, Tubingen, Germany; outer diameter 1.9 mm, length 900 mm) followed by 6-10 pleural biopsy specimens obtained using the flexible thoracoscopic forceps (FB-55CR, Olympus Medical Systems, 2 mm diameter).

Forceps biopsy

Pleural biopsy with a flexible forceps

Group Type ACTIVE_COMPARATOR

Flexible forceps biopsy first

Intervention Type DEVICE

Six to ten pleural biopsy specimens will be obtained using the flexible thoracoscopic forceps (FB-55CR, Olympus Medical Systems, 2 mm diameter) followed by four pleural biopsy specimens obtained using the flexible cryoprobe (ERBOCRYOCA, ERBE, Tubingen, Germany; outer diameter 1.9 mm, length 900 mm)
