BACKGROUND: Primary spontaneous pneumothorax (PSP) usually occurs in young adults, with higher incidence in smoker, and patients with narrow chest frame and slim body habitus. Surgery is indicated in the cases of recurrence episodes or persistent lung collapse, and failed conservative management by chest drain insertion. Video assisted thoracoscopic surgery (VATS) bullectomy and pleurodesis is the surgical treatment of choice but uniportal approach has been utilised to further minimise surgical trauma, improve cosmesis without compromising the efficacy of the procedure.
METHODS: This video demonstrated the uniportal procedure for bullectomy and double pleurodesis for PSP. A 2.5 cm incision was made at 4th intercostal space, anterior axillary line. Extra small size wound protector was used and CO2 insufflation was not needed. Adhesion divided with diathermy and visible apical bullae was resected using endoscopic stapler. Abrasive pleurodesis performed by using scratch patch mounted on Robert clamp, gently running along the parietal pleura within the chest wall. In addition, 5 grams of pure talc was delivered into pleural space. Single drain inserted via the port and lung fully inflated upon resuming ventilation by anaesthetist. Drain remained for 48 hours under negative pressure of -20 mmHg and patient usually went home on day 3 post-operatively.
RESULTS: During the period from 2009 to 2015, over 160 cases of PSP were treated using this method by the author. To date, there is no recurrence reported upon follow up at outpatient clinic. There was no mortality and patients resumed active physical activity 8 weeks after the procedure.
CONCLUSIONS: Uniportal VATS bullectomy and double pleurodesis is a safe procedure for treating PSP and effective in preventing future recurrence of lung collapse. This simple approach should be encouraged and performed by all enthusiastic VATS thoracic surgeons.
Fulltext Uniportal video assisted thoracoscopic surgery thymectomy (right approach)

BACKGROUND: Video assisted thoracoscopic surgery (VATS) thymectomy for the management of myasthenia gravis and thymoma has been described and routinely performed. With the advent of single port surgery, uniportal thymectomy has gained popularity as it has the advantages in terms of improved cosmesis, less surgical trauma and financial savings in particularly over robotic thymectomy. The approach demonstrated in this video also negates the problems of sub-xiphoid route in patient with obesity, cardiomegaly, and limitations of instruments manoeuvrability.
METHODS: Patient positioned semi-supine with right sided propped up and the ipsilateral arm placed naturally and secured by the side and below the chest wall. Cleaned and draped as for sterile procedure. General anaesthesia and lung isolation achieved with a double lumen endotracheal intubation. A 2.5 cm incision was made at 5(th) intercostal space, anterior axillary line (lateral to nipple line). Extra small size wound protector was used and CO2 insufflation was not needed. Instruments utilised in this case were "not new" and used for laparoscopic surgery 2 decades ago. This video demonstrates the simple technique of right uniportal approach to total thymectomy. Safe en bloc dissection of thymus and thymic tumour with surrounding fatty tissue were performed by combination of careful pleura dissection using diathermy, traction and blunt dissection of thymus. Extra caution when dividing thymic vein branches from innominate vein is prudent in all thymic dissection and prevent intra-operative haemorrhage and subsequent conversion to sternotomy or thoracotomy.
RESULTS: In this video, total thymectomy was performed without complication. The specimen was removed through the port and a single chest tube was placed at end of procedure for 1 day. Patient went home uneventfully on day 2.
CONCLUSIONS: Right uniportal VATS thymectomy is feasible, and this simple approach should be encouraged and performed by all enthusiastic VATS thoracic surgeons.
Fulltext Uniportal video assisted thoracoscopic surgery thymectomy (left approach)

Ooi A, Qiang F

BACKGROUND: Video assisted thoracoscopic surgery (VATS) thymectomy for the management of myasthenia gravis and thymoma has been described and routinely performed. With the advent of single port surgery, uniportal thymectomy has gained popularity and left side approach is preferred only if the suspecting tumour is situated on the left mediastinum. However, many doubt or dislike the left side VATS approach to anterior mediastinum as the ventricular apex renders maneuverer of instruments difficult. This is certainly not the case as shown in this video and to date, there is no published manuscript on left uniportal thymectomy.
METHODS: Patient positioned semi-supine with left sided propped up and the ipsilateral arm placed naturally and secured by the side and below the chest wall. Cleaned and draped as for sterile procedure. General anaesthesia and lung isolation achieved with a double lumen endotracheal intubation. A 2.5 cm incision was made at 4(th) intercostal space, anterior axillary line (lateral to nipple line). Extra small size wound protector was used and CO2 insufflation was not needed. Instruments utilised in this case were "not new" and used for laparoscopic surgery 2 decades ago. This video demonstrates the simple technique of left uniportal approach to total thymectomy. Safe en bloc resection of thymus and thymic tumour with surrounding fatty tissue were performed, by combination of careful pleura dissection using diathermy, traction and blunt dissection of thymus. Extra caution when dividing thymic vein branches from innominate vein is prudent in order to prevent intra-operative haemorrhage and subsequent conversion to sternotomy or thoracotomy.
RESULTS: In this video, total thymectomy was performed without complication. The specimen was removed through the port and a single chest tube was placed at end of procedure for 1 day. Patient went home uneventfully on day 2.
CONCLUSIONS: Left uniportal VATS thymectomy is feasible, and preferred for left sided thymoma. This simple approach should be encouraged and performed by all enthusiastic VATS thoracic surgeons.
Fulltext Subxiphoid uniportal lobectomy

Video-assisted thoracic surgery (VATS) surgery has seen an evolution from multiple ports to uniportal and finally subxiphoid uniportal recently. In traditional VATS surgery, the instruments and the thoracoscope enter the thoracic cavity through two to four operating ports on the lateral chest wall, which can cause chronic pain and chest wall numbness. However single-portal VATS surgery could potentially cause similar problems as the port is placed in between the ribs. In March 2015 Liu et al. reported a VATS bilateral pulmonary metastasectomy and right middle lobectomy via a subxiphoid uniportal technique. The advantage of the uniportal subxiphoid approach is the ability to use different size of instruments and freedom of movement as there is no limitation by the ribs. Post-operative pain typically experienced due to bruising of the intercostal nerves is also avoided in this approach. Shanghai Pulmonary hospital has taken VATS surgery to the next level with subxiphoid uniportal VATS (SVATS) lung resection, whereby this method is performed in large volumes of cases. Here we describe our experience of a uniportal subxiphoid VATS right middle lobectomy using the Shanghai technique, the first in the UK. A uniportal sub-xiphoid lobectomy was performed on a 62-year-old lifelong smoker male patient with a histological diagnosis of right middle lobe adenocarcinoma, measuring 1.5 cm and radiological staging of T1aN0M0. We have been performing microlobectomies in our institution (with the utility port placed in the subxiphoid region) which is technically similar to this approach. This is the first subxiphoid uniportal lobectomy performed in the UK. The operation was done successfully and the patient was discharged home 2 days later without any complications.
