Background: In recent years, open heart surgery has developed rapidly in Vietnam. Sternal infection is a very serious complication for this surgery, it lead to increasing treatment costs and higher risk of mortality. Treatment of local infections is always a difficult technique in sternal wound infections after open heart operations. Objectives: (1) To improve and apply two techniques called \u201cdemi \ufffd?open + irrigation\ufffd? and \u201cclosed \ufffd?Redon drainage\ufffd? (2) To evaluate the effects of these techniques. Subjects and method: 20 cases of sternal infection (at Viet Duc hospital and some other hospitals in Ha Noi) were researched and described prospectively about diagnosis, techniques and treatment results. The subjects were divided in to 2 group based on the infection processing techniques. Results:Diagnosis had to reply on clinical signals (100%). Bacterial culture only provided 45% positive results, Pseudomonas aeruginosa (44.4%) were obtained more than Staphylococcus au\u2019reus (22.2%). Both techniques have their own reasonable creativeness and the standardized process, improving the limitations of ordinary technique, providing high treatment effectiveness \ufffd?85% have recovered after only one operation. Conclusion: For treatment of local infections, two techniques are both very efficient and suitable with the conditions in Vietnam, especially \u201cclosed \ufffd?Redon drainage\ufffd?technique.

The rapid development and promotion of minimally invasive thoracic surgery represented by video-assisted thoracoscopy surgery has gradually replaced traditional thoracic surgery technique as the primary choice for the treatment of pulmonary nodules, including early lung cancer. With the clinical application of double-lumen bronchial catheters, the realization of one-lung ventilation technology not only provides a solid anesthesia foundation for the popularization of minimally invasive thoracic surgery, but also provides a guarantee for the rapid and smooth implementation of the operation. However, compared with single-lumen bronchial catheters, the diameter of the double-lumen bronchial catheter is thicker, and the tube body is hard and difficult to shape, which brings inconvenience to anesthesia intubation. The bronchial structure is different, and the incidence of dislocation during anesthesia intubation is also high. With the gradual clinical use of video double-lumen tube (VDLT), it has become a hot spot in thoracic surgery in recent years. This article reviews the application and research progress of VDLT in thoracic surgery.

BACKGROUNDThe advantages of video assisted thoracoscopic anterior correction for scoliosis are minimal invasion and relatively short-time instrumentation; however the relatively steep learning curve cannot be ignored. Small incision, thoracotomic anterior correction for idiopathic thoracic scoliosis could be another choice because of less demanding technique. We compared the outcomes of these two techniques.

METHODSForty-nine patients with idiopathic right thoracic scoliosis were randomly divided into two groups. Group A was 12 girls with mean age 14.9 years, mean Cobb angle 52 degrees and Risser signs "+++" to "++++". Ten patients received video assisted thoracoscopic anterior correction with Eclipse rectification and two with Frontier instrumentation. Group B was 4 boys and 33 girls with mean age 14.1 years, mean Cobb angle of 56 degrees and Risser signs "++" to "++++". These patients underwent small incision, thoracotomic anterior instrumentation. The operation time, blood loss, postoperative drainage, instrumented levels, curve correction and early loss of correction of both groups were analyzed.

RESULTSGroup A had average operation time of (390+/-82) minutes, intraoperative blood loss of (600+/-155) ml, instrumented level of 7.4+/-1.3, postoperative drainage of (500+/-160) ml, correction rate of (65+/-16)% and loss of correction during the 18-36 month followup of (8.6+/-2.9)%. Group B had average operative time of (220+/-80) minutes, intraoperative blood loss of (320+/-120) ml, instrumented level of 7.8+/-0.9, postoperative drainage of (210+/-90) ml, curve correction rate of (70+/-12)% and loss of correction during the 18-36-month followup of (4.6+/-3.9)%. The curve correction rates of the two groups were not statistically significant (P>0.05). However, the operative time, blood loss, postoperative drainage, and early loss of correction showed statistical significance (P<0.05).

CONCLUSIONBoth video assisted thoracoscopic anterior correction and small incision thoracotomic anterior correction are safe and effective in correcting the idiopathic thoracic scoliosis.

Today, with the rapid development of network information technology, the micro-lecture plays a role in the teaching activities is becoming more and more important. The short and efficient teaching content of micro-lecture can be downloaded rapidly, expediently, and repeatedly, which improve the learning efficiency and independent learning capability. The clinical training of thoracic surgery elementarily remains at the scrabble stage. We require continuous reform and introduce new modes of teaching, which compatible with the development of society and the study habits of novice, to enhance the effectiveness of clinical training. In this paper, the concept, characteristic and advantage of micro-lecture was discussed, and the feasibility of application of micro-lecture in thoracic surgery teaching was also discussed. Our aim was to promote the application of micro-lecture in the clinical training of thoracic surgery reasonable and extensive.

BACKGROUND: A method of wound closure using knotless suture material in the chest tube site has been introduced at our center, and is now widely used as the primary method of closing chest tube wounds in video- assisted thoracic surgery (VATS) because it provides cosmetic benefits and causes less pain. METHODS: We included 109 patients who underwent VATS pulmonary resection at Samsung Medical Center from October 1 to October 31, 2016. Eighty-five patients underwent VATS pulmonary resection with chest drain wound closure utilizing knotless suture material, and 24 patients underwent VATS pulmonary resection with chest drain wound closure by the conventional method. Complications related to the chest drain wound were compared between the 2 groups. RESULTS: There were 2 cases of pneumothorax after chest tube removal in both groups (8.3% in the conventional group, 2.3% in the knotless suture group; p=0.172) and there was 1 case of wound discharge due to wound dehiscence in the knotless suture group (0% in the conventional group, 1.2% in the knotless suture group; p=0.453). There was no reported case of chest tube dislodgement in either group. The complication rates were non-significantly different between the 2 groups. CONCLUSION: The results for the complication rates of this new chest drain wound closure method suggest that this method is not inferior to the conventional method. Chest drain wound closure using knotless suture material is feasible based on the short-term results of the complication rate.

BACKGROUNDVideo-assisted thoracoscopic sympathectomy had replaced open surgery. The aim of this study was to compare the outcomes of using a single port and two ports to perform video-assisted thoracoscopic sympathectomy for palmar hyperhidrosis.

METHODSBetween April 2006 and February 2008, 20 cases underwent video-assisted thoracoscopic sympathectomy through one port (uniportal group) and 25 cases through two ports (biportal group). The variables including the operating time, hospital stay, pain scores, postoperative complications, incidence of symptom recurrence and patient satisfaction were compared. The mean postoperative follow-up period was 11.5 months (range, 3 - 25 months).

RESULTSThe hands of all patients were warm and dry after operation. No conversion to open surgery was necessary, and no operative mortality was recorded in either group. The mean inpatient pain scores were significantly higher in the biportal group (1.2 +/- 0.6) than that in the uniportal group (0.8 +/- 0.5, P = 0.025). For the first three weeks after operation, four out of 20 (20%) patients in the uniportal group constantly suffered from mild or moderate residual pain while eight out of 25 (32%) cases in the biportal group (P = 0.366). Among them, two cases in the uniportal group and five cases in the biportal group need to take analgesics. Our mean operative time (bilateral sympathectomy) in the uniportal group ((39.5 +/- 10.0) minutes) was shorter than that in biportal group ((49.7 +/- 10.6) minutes, P = 0.02). There were no significant differences between two groups in terms of the mean hospital stay, compensatory sweating, and patient satisfaction. Two patients in the biportal group and three in the uniportal group experienced a unilateral pneumothorax. None of them required chest drainage. No patient experienced Horner's syndrome, and no recurrent symptoms were observed in either groups.

CONCLUSIONSBoth uniportal and biportal video-assisted thoracoscopic sympathectomy are effective, safe, and minimally invasive for palmar hyperhidrosis. Comparing with the biportal approach, the uniportal approach causes less postoperative pain and less operative time, and is a more reasonable procedure in treatment of palmar hyperhidrosis.

BACKGROUND: Patients who underwent lobectomy resection are prone to hypoxemia, and the vast majority present with type I respiratory failure. Thus, improvement of hypoxemia is one of the most important factors to facilitate postoperative recovery of patients. In this study, the superiority-inferiority of different oxygen inhalation methods were compared with high-flow nasal oxygen therapy (HFNO), noninvasive mechanical ventilation (NIMV) and nasal oxygen breath (NOB) in patients with hypoxemia after single-port video-assisted thoracoscopic (VATS) lobectomy, and the clinical efficacy of HFNO in these patients was further investigated. METHODS: A total of 180 patients from the Second Affiliated Hospital of Soochow University in China with hypoxemia who accepting single-port VATS lobectomy from June 2021 to March 2022 were randomly divided into three groups (n=60), which were treated with HFNO, NIMV and NOB, respectively. The results of arterial blood gas analysis, patient's comfort score and incidence of complications were observed before, 1 h, 6 h-12 h and after use. Statistical analyses were conducted using statistical program for social sciences 25.0 (SPSS 25.0), and P<0.05 was considered as statistical significance. RESULTS: For patients with hypoxemia after accepting single-port VATS lobectomy, HFNO was no less effective than NIMV (P=0.333), and both of whom could fast increase patients' partial pressure of oxygen/fraction of inspiration O₂ (PaO₂/FiO₂) compared to NOB (P<0.001). Besides, HFNO shows a great advantage in comfort degree and stay length (P<0.001, P=0.004), and incidence of complications were slightly lower than other groups (P=0.232). But it is worthy to note that HFNO is still slightly less effective than NIMV in patients with postoperative hypoxemia accompanied by elevated partial pressure of carbon dioxide (PaCO₂). CONCLUSIONS For patients with hypoxemia who accepting single-port VATS lobectomy, HFNO can be used as the first choice. However, for patients with postoperative hypoxemia accompanied by elevated PaCO₂, NIMV is still recommended to improve oxygenation.

Near-infrared (NIR) fluorescence imaging provides a safe and cost-efficient method for immediate data acquisition and visualization of tissues, with technical advantages including minimal autofluorescence, reduced photon absorption, and low scattering in tissue. In this review, we introduce recent advances in NIR fluorescence imaging systems for thoracic surgery that improve the identification of vital tissues and facilitate the resection of tumorous tissues. When coupled with appropriate NIR fluorophores, NIR fluorescence imaging may transform current intraoperative thoracic surgery methods by enhancing the precision of surgical procedures and augmenting postoperative outcomes through improvements in diagnostic accuracy and reductions in the remission rate.

OBJECTIVETo evaluate the result of surgical treatment of the middle and upper-middle esophageal carcinoma with a new operation, performing the anastomosis posterior to the aortic arch at the apex of the thoracic cavity.

METHODSFrom April 1996 to May. 2000, 179 patients with esophageal carcinoma were treated. Sixty-eight of these patients (49 in the middle and 19 in the upper-middle segment) were treated by esophogogastrostomy at the top of the chest, posterior to the aortic arch. There were squamous cell carcinoma 50, adenocarcinoma 16, undifferentiated carcinoma 2, including 8 double-primaries. The lesions were stage I 9 and stage II-III 59.

RESULTSAll patients have been alive after follow-up of 2 months to 3 years. Without any positive margins, anastomotic leak or perioperative death, this new method has merits: 1. Length of esophagus resected was maximal through one single incision. It would be especially useful for some of the upper-middle lesions. 2. This new method requires a shorter transposed stomach than that required by the combined triple cervico-thoraco-abdominal approach. 3. As the site of thoracic stomach was on the bed of esophagus, there was less chance of post-operative embarrassment in respiration due to the dilatation of the transpositioned stomach and pylorostenosis, etc. 4. There would be less chance of reflux esophagitis because of the "blocking" by the aortic arch, thereby, the patients life is improved.

CONCLUSIONThis radical operation for esophageal carcinoma with anastomosis at top of the thoracic cavity posterior to the aortic arch, being a newly designed surgical method, is especially useful for carcinoma in the middle and upper-middle esophageal segment.
