 The third mediterranean symposium on thoracic surgical oncology was  successful.  The symposium was held the 21st – 22nd april 2016  at the Aula Magna of the Faculty of Medicine at the University of Catania. More than 150 people attended, and among them there were thoracic surgeons, general surgeons, oncologists, chest physicians, residents and medical students.  This year, we had speakers from Europe and the USA.  The main topic was VATS resections for lung cancer (Photo 1). During the opening ceremony, the Rector Giacomo Pignataro awarded a medal to Professor Tom Treasure for enhancing our outstanding education and research experience (Photo 2).

Although the concept of operating thru a small port was born and developed in Europe (1- 7) it has been noted that 90% of papers on uniportal VATS lobectomy come from East Asian countries (8-11).  Throughout the symposium  different speakers agreed that a  proper definition of uniportal VATS is mandatory to speak the same language worldwide.

Awake thoracic surgery was discussed together with the need of accurate  preoperative staging procedures such as endobronchial ultrasound, videomediastinoscopy or Video-assisted mediastinal lympadenectomy.   It was concluded that a wide spectrum of factors must be considered when determining the appropriate tests to assess the lymph nodes in  NSCLC, which includes not only the sensitivity and specificity of the test,  but also the ability to perform  the procedure on an individual patient.

Data from New York showed very clearly that there have been no large-scale randomized control trials to compare open and VATS lobectomy. Although most may agree with the short-term superiority of VATs lobectomy over its open counterpart, many argue that is an in adequate oncologic procedure. Hence whether the approach is equivalent in overall and cancer specific survival to its open counterpart is not known. He also reported an important recent analysis of SEER-Medicare which confirmed that VATS lobectomy appears to have similar survival to its open counterparts (12).

A magnificent video was presented to explain every step of the lobectomies performed through a small skin incision.  A long discussion followed and all auditorium proposed that ‘single incision’ VATS probably define better than uniportal VATS what surgeons are doing worldwide. Certainly the length of skin incision is important and should be taken in serious consideration.  We felt that a consensus conference is probably necessary  consensus conference is probably necessary.  The indication for a Wedge resection rather than lobectomy in initial stage lung cancer is still weak.

The Italian VATS group was formed in 2013 , and nowadays there are 65 participating centres and that 2800 VATS lobectomy have already been included. In Catania we joined the group few months ago (13)

A very interesting session for juniors and medical students from UK and Italy was carried out,  and 12 abstracts have been presented as interactive posters.  Two of them have been chosen for possible publication in Future Oncology.

Finally, the first data survival seems to benefit little from the various even growing “personal” modifications of the standard VATS technique. Since there is a limited variation between VATS and uniportal VATS, the likelihood is that either VATS and uniportal VATS will be operative in the near future. Its success will depend on survival advantages and decrease chest pain  and not just on new technical instrumentation. To protect patient’s safety, the length  of the skin incision should  be chosen on the basis of several clinical factors and not in relation of modern “demand”.  Although the trial VIOLET is ongoing in UK to demonstrate if VATS resection for lung cancer is better than open thoracotomy, doubts arises  as standard postero-lateral thoracotomy for lung cancer seems to be an incision which is performed rarely today.  A skin incision of 6-8 cm (mini-thoracotomy) with video assistance is enough for most of lung resections. The question which arises is if a mini-thoracotomy of 6 cm should be called “uniportal” or not.

Munich airport, Germany

I am on the last leg of a long journey to the beautiful southern Italian coastal city of Naples.  Best known for its claim as the home of pizza and the nearby ruins of Pompeii, for the next few days, the department of thoracic surgery at Hospital Monaldi will be hosting surgeons (and one wee writer) from around the world for a two day course on minimally invasive and robotic surgery.

The event features live surgery demonstrations by Dr. Henrik Hansen and Dr. Diego Gonzalez Rivas, with a host of other speakers.  For more details on the V corso VATS Monaldi Napoli dr Curcio dr Amore dr Casazza click the highlighted link for the full program.

Meanwhile, I will bring readers photos and highlights from the event.

Controlling prolonged air leak by remote control

Dr. Gaetano Rocco talks about persistent air leaks and the development of a remote-controlled computer assisted suction device.

An air leak lasting longer than 5 to 7 days is considered a ‘prolonged or persistent air leak*’.

A prolonged air leak is one of the most frustrating complications after thoracic surgery for patients and clinicians alike.  Far from being life- threatening, a prolonged air leak often occurs in patients that are otherwise stable, healing well and potentially ready for discharge.  However, the presence of a persistent air leak can change all that – by limiting patient mobility and prolonging their hospital stay.

Surgeons have attempted to manage this problem in multiple ways in the past; including additional surgery, application of intra-operative glues and other sealants, repeated post-operative pleurodesis and the implantation of long-term devices like the Heimlich valve (to evacuate air while the lung heals).

More radical therapies such as radiation and endobronchial valves (EBV) have also been used with varying degrees of success (Erdoğan Çetinkaya, M. Akif Özgül, Şule Gül, Ertan Çam, Yakup Büyükpolat, 2012).

Ambulatory suction

In this study, Rocco designed a device capable of providing differing levels of suction independent of wall mounted suction**.  This in itself, is an important feat since being reliant on wall-mounted suction significantly limits the mobility and activity of otherwise ambulatory patients.

In standard cases, patients are essentially tethered to the suction mount in their rooms by a short length of suction tubing. This prolongs hospitalization and can contribute to the development of additional complications.

The Heimlich valve is often used in these cases to allow patients to be discharged home, despite a persistent air leak.  However, while the Heimlich valve relieves patients of this reliance on wall suction, this is also one of it’s limitations.  Independent of wall suction, the Heimlich valve prevents the entry of additional air into the pleural space but can not provide active suction to assist in lung healing.

Prior portable suction technologies

In my experience, our hospital had several antiquated portable suction units that allowed for limited ambulation.  These units were electric-powered suction units that could be wheeled alongside the patient (similar to wheeled oxygen units.)  But these units (dating from the 1950’s – 1960’s and which were found & rehabilitated from an old equipment room) still required the patient to remain in contact with a grounded electrical outlet, though the cord was lengthy.  They were used in limited circumstances in the intensive care and step-down units.

Dr. Rocco’s device is a significant upgrade from the 1950’s version, and contains computer sensors to detect, and change the level of suction as needed.  It also contains a chargeable battery that allows patients to function independent of an electrical outlet for up to 48 hours.  This offers considerable freedom, and even permits home use in stable patients.

Continuous patient monitoring

With a laptop computer, both the surgeon and the patient can keep in contact, and monitor progress.  The surgeon can also adjust the amount of suction and review the continuously recorded air leak data.

In this case report, Rocco and his colleagues trialed the equipment  on a patient with a persistent air leak after a right upper lobectomy with wedge resection of the right lower lobe.  The patient was treated and monitored with this device during a stay in the step-down unit, the thoracic floor and finally, in an outpatient setting at a nearby guest house.

While this is a preliminary trial involving a single patient, the potential uses of these technology are considerable – given the frequency of prolonged air leaks post-operatively.  This is also important to consider as minimally invasive surgeries make it possible for patients to be medically stable and otherwise eligible for discharge earlier in the post-operative course.  Given the inherent risks (and costs) of prolonged hospitalization – this may become a viable option a part of a comprehensive discharge plan for many patients who would otherwise remain tethered to a suction mount in a hospital room.

Conference coverage: Bolivian Society of Cardiac, Thoracic and Vascular Surgery

Notes from the day’s lectures at the XVI Congreso Boliviana de Cirugia Cardiaca, Toracica u Vascular in Santa Cruz de la Sierra, Bolivia

This afternoon’s thoracic surgery offerings were provided in a more relaxed, round-table style discussion.

Relaxed roundtable discussion – Latin American surgeons. (Dr. Fernando Bello is the second from the left)

Dr. Edwin Crespo Mendoza, thoracic surgeon, of Santa Cruz, Bolivia led the discussion on diaphragmatic hernia repair and reminded the audience that over 50% of traumatic diaphragmatic hernias go undiagnosed at the time of initial presentation after trauma.  To illustrate this, Dr. Crespo presented several cases including a case of post-traumatic hernia diagnosed 13 years after initial auto accident.

Dr. Fernando E. Jemio Ojara, MD (cardiothoracic surgeon) here in Santa Cruz at the Clinica Folanini presented a fascinating case of bilateral lung injury after blunt trauma.  In this case, the patient was preparing to undergo urgent repair of a right-sided bronchial tear but during attempted intubation saturations dropped dramatically to 60%.  At that time, the patient was placed on ECMO by venous cannulation to maintain oxygenation during the case.   The surgeons proceeded with a right posteriolateral thoracotomy.  Patient had a short successful ECMO run of 85 minutes, with extubated within 36 hours of surgery, and had no further problems post-operatively,

Dr. Ojara also discussed the mechanism of these type of acceleration – deceleration injuries that most commonly affect the right middle lobe, and how stabilization with ECMO is an effective strategy to repair what is essentially a functional pneumonectomy (in this particularly patient).

Dr. Fidel Silva Julio, Thoracic Surgeon also talked on a similar theme in his overview of closed chest trauma.  He reminded the audience that 75-85% of all closed chest trauma patients need some sort of surgical management from chest tube placement to urgent surgery.  He  reviewed the classic presentations and radiographic findings in some of the most common conditions after chest trauma such as tension pnuemothorax/ sucking chest wounds, flail chest, pneumomediastinum, cardiac tamponade and pulmonary contusions.  There were several medical students in the audience, taking notes – so I have included links to the radiology signs mentioned in his lecture, as well as a basic radiology primer.

He also highlighted the need to prevent the typical trauma pitfall of massive volume resuscitation which can prove extremely detrimental in these patients.
