Detailed Description
The primary objective of this study is to compare two independent groups of patients requiring lung biopsy for undetermined interstitial lung disease (ILD) in terms of diagnostic confidence as determined by histologists. The experimental arm will be operated under a neoteric non-intubated video assisted thoracic surgery (NIVATS) technique and the comparator arm under a usual intubated general anaesthesia video-assisted thoracic surgery (IGAVATS) technique.
Secondarily, the two groups will also be compared in terms of: (i) further variables associated with histology, biopsy quality and size; (ii) surgical performance, (iii) patient trajectories and lung function; (iv) quality of life, and (v) harms.

Outcome Measures
Primary Outcome Measures
- The level of diagnostic confidence based on centralized histology only [Day 1 to day 15]
The level of diagnostic confidence for a given diagnosis is established according to a quantitative scale ranging from '0' (absolute rule-out) to '10' (diagnostic certainty). A visual guide for scale use is provided with scores <1 corresponding to "alternate diagnosis", scores >=1 and <4 corresponding to "indeterminate", scores >=4 and <7 corresponding to "probable", and scores >=7 corresponding to "highly probable" categories.
Secondary Outcome Measures
- The level of diagnostic confidence based on routine histology only [Day 1 to day 15]

A visual guide for scale use is provided with scores <1 corresponding to "alternate diagnosis", scores >=1 and <4 corresponding to "indeterminate", scores >=4 and <7 corresponding to "probable", and scores >=7 corresponding to "highly probable" categories.
- The level of diagnostic confidence achieved at multidisciplinary assessment (MDA)-2 [Day 7 to day 28]
The level of diagnostic confidence for a given diagnosis is established according to a quantitative scale ranging from '0' (absolute rule-out) to '10' (diagnostic certainty). A visual guide for scale use is provided with scores <1 corresponding to "alternate diagnosis", scores >=1 and <4 corresponding to "indeterminate", scores >=4 and <7 corresponding to "probable", and scores >=7 corresponding to "highly probable" categories.

- Euroqol 5 dimensions 5 levels questionnaire: mobility dimension score [Day -28 to Day -1]
In its original version, this self-administered questionnaire consists of two pages: the first contains the EQ-5D descriptive system and the second a visual analogue scale. The descriptive system has five dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression), each described by five levels of intensity ("no problems", "slight problems", "moderate problems", "severe problems" and "extreme problems or complete inability"). The respondent must indicate one intensity level for each dimension.
