Thoracoscopy is used regularly in the diagnosis and
management of pleural disease. The pleural space can
be visualized by using a variety of instruments, including a
rigid pleuroscope, a flexible bronchoscope and a specially
designed thoracoscope coupled to a microcamera system.
Current rigid instruments have a large calibre and often result
in painful incisions, especially when the intercostal space is
narrow. We describe our approach to investigating and treat-
ing pleural effusions using a new 2 mm thoracoscope (Min-
iSite 2 mm 0° Laparoscope, Auto Suture Company).
TECHNIQUEThe procedure is carried out under general anesthesia with
single-lung ventilation using a double-lumen endotracheal
intubation. The patient is placed in the lateral thoracotomy
position. The pleural space is entered via a 3 mm incision us-
ing a curved hemostat (Figure 1). A small trocar (MiniSite
Introducer, Auto Suture Company) is used as a trocar for the
2 mm miniscope. The scope is then inserted through the tro-
car to allow direct visualization of the pleural space. The
scope may be attached to a standard video camera for full
on-screen visualization if desired. Pleural fluid is aspirated
using the side tubing or via a second 3 mm hole through an-
other mini-introducer. Pleural or tumour biopsies are taken
under direct vision through the second MiniSite Introducer.
Pleurodesis, if desired, can be achieved using 5 g of sterile
talc mixed in 100 mL saline as a slurry through either the sec-
ond trocar or via the side tubing of the camera port. A 20
French chest tube is inserted through the camera port and is
placed to 20 cm underwater suction.

The current management of pleural disease often requiresdirect visualization and biopsy of the pleural space using tho-racoscopy. A diagnostic and therapeutic approach to pleuraldisease is described that uses a new 2 mm rigid thorascope.The technique allows complete visualization, biopsy anddrainage of the pleural space with rapid recovery and mini-mal pain.

RÉSUMÉ : Le traitement actuel des affections pleuralesexige souvent la visualisation directe et une biopsie de la ca-vité pleurale à l’aide d’un thoracoscope. Dans le présent arti-cle, il est question d’une intervention diagnostique et thé-rapeutique qui se pratique au moyen d’un nouveauthoracoscope rigide de 2 mm. La technique décrite non seu-lement permet une visualisation complète, une biopsie et ledrainage de la cavité pleurale, mais s’accompagne d’une ré-cupération rapide et de très peu de douleurs.

RESULTSThis technique was performed on three patients with
uncomplicated pleural effusions. The visualization of the
pleural space was excellent, and biopsies were completed
in two of the three patients. One patient had a traumatic
serous effusion that was drained. The second patient had
a malignant effusion secondary to a breast carcinoma that
was successfully pleurodesed. In the third patient, the
miniscope was used to confirm the presence of an en-
trapped lung and a loculated effusion secondary to a
mesothelioma. All procedures were either diagnostic or
therapeutic. Patients’ postoperative pain was minimal.
The lengths of hospital stay were two, three and five days,
respectively.
DISCUSSIONMinithoracoscopy with the 2 mm thoracoscope provides an
alternative to standard pleuroscopy for the diagnosis and ther-
apy of pleural disease. The scope is, however, a delicate instru-
ment that can easily be damaged if used with excess vigour. It
retains all of the advantages of standard video-assisted tech-
nique with the added benefit of less pain and a smaller inci-
sion. Preliminary experience supports this technique as less
painful and equally effective as standard methods.
