[Comparison Study of Post-operative Pain and Short-term Quality of Life between Uniportal and Three Portal Video-assisted Thoracic Surgery for Radical Lung Cancer Resection]

[Comparison of Quality of Life of the Patients Three Months after Uniportal and Multiportal Thoracoscopic Lobectomy]

BACKGROUND

The relationship between quality of life at three months after lung cancer surgery and different surgical approaches is remains unclear. This study aimed to compare the quality of life of patients three months after uniportal and multiportal thoracoscopic lobectomy.

METHODS

Data from patients who underwent lung surgery at the Department of Thoracic Surgery, Sichuan Cancer Hospital between April 2021 and October 2021 were collected. The European Organization for Research and Treatment of Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and Quality of Life Questionnaire-Lung Cancer 29 (EORTC QLQ-LC29) were used to collect quality of life data of the patients. Potential confounding factors in the baseline data were included in a multivariate regression model for adjustment, and the quality of life of the two groups three months postoperatively was compared with traditional clinical outcomes.

RESULTS

A total of 130 lung cancer patients were included, with 57 males (43.8%) and 73 females (56.2%), and an average age of (57.1±9.5) yr. In the baseline data of the two groups, there was a statistical difference in the number of chest drainage tubes placed (P<0.001). After adjustment with the regression model, at three months postoperatively, there were no significant differences in all symptoms and functional status scores between the two groups (all P>0.05). The multiportal group had longer surgery time (120.0 min vs 85.0 min, P=0.001), postoperative hospital stay (6.0 d vs 4.0 d, P=0.020), and a higher incidence of early ≥ grade 2 complications (39.0% vs 10.1%, P=0.011) compared to the uniportal group.

CONCLUSIONS

Patients undergoing uniportal and multiportal thoracoscopic lobectomy have similar quality of life at three months postoperatively. The uniportal group may have certain advantages in terms of traditional clinical outcome indicators such as operation time, postoperative hospital stay, and early postoperative complications.

The effects of different surgical approaches on the psychological status, medical coping mode and quality of life of patients with lung cancer

Objective

This study aimed to compare the effects of robot-assisted thoracic surgery (RATS), video-assisted thoracic surgery (VATS), and thoracotomy on the psychological status, medical coping mode, and quality of life of patients with lung cancer.

Methods

A total of 158 patients with lung cancer were selected from the thoracic surgery center of a third-grade hospital in Hunan Province, China, from September to November 2020. The Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), Medical Coping Modes Questionnaire (MCMQ), and Medical Outcomes Study (MOS) 36-item Short Form Health Survey (SF-36) were used to assess the effects of the surgical approaches on the study parameters before and 48–96 h after surgery. The t-test and analysis of variance were used to analyze the data.

Results

The results revealed that the patients’ depression increased, their short-term quality of life decreased, and they tended to adopt a positive coping mode after surgery (p &lt; 0.05). The RATS and VATS groups differed in avoidance dimension of medical coping modes (p &lt; 0.05). The VATS and thoracotomy groups differed in the body pain dimension of quality of life (p &lt; 0.05). Different surgical approaches had no effect on the psychological status, medical coping modes except the avoidance dimension, and quality of life except the body pain dimension.

Conclusion

Surgical approaches have little effect on the psychological status, medical coping modes, and quality of life of patients with lung cancer; however, their depression increased and quality of life decreased after the surgery.

Comparison of Inflammatory Cytokine Levels between Single-Port and Three-Port Thoracoscopic Lobectomy in the Treatment of Non-Small-Cell Lung Cancer

Introduction

Thoracoscopic minimally invasive surgery is the main method for the treatment of lung cancer. The reduction of surgical trauma can effectively reduce the intraoperative and postoperative inflammatory reaction. The aim of the study is to compare the intraoperative and postoperative inflammatory reactions in patients with non-small-cell lung cancer (NSCLC) treated by single-port thoracoscopic surgery and three-port thoracoscopic surgery.

Methods

A total of 68 NSCLC patients (stages I and II) of thoracoscopic surgery were selected and randomly divided into two groups where they received either single-port thoracoscopic surgery or three-port thoracoscopic surgery. Intraoperative and postoperative serum inflammatory markers (C-reactive protein, CRP; serum amyloid A protein, SAA; and interleukin 6, IL-6) were detected using the enzyme-linked immunosorbent assay.

Results

The CRP level of the single-port group was significantly lower than that of the three-port group during surgery, the first day after surgery, and third day after surgery (P < 0.05). The level of IL-6 in the single-port group was significantly lower than that in the three-port group during surgery on the first and third days after surgery (P < 0.05). The level of SAA in the single-port group was also significantly lower than that in the three-port group on the first and third days after surgery (P < 0.05).

Conclusion

Compared with three-port thoracoscopic surgery, single-port thoracoscopic surgery could reduce the inflammatory response and improve the recovery of NSCLC patients. Single-port thoracoscopic surgery is worthy of further promotion in the current treatment field of NSCLC in terms of reducing intraoperative and postoperative inflammatory reactions.

Pretreatment clamping of pulmonary artery during uniportal thoracoscopic lobectomy

Background

Intraoperative pulmonary artery (PA) hemorrhage is one of the leading reasons for conversion from uniportal VATS to open thoracotomy, especially for the small incision (≤3 cm) uniportal VATS performed by our department. So, We designed a technology called pretreatment clamping of the pulmonary artery, which may be helpful to solve the problem.

Methods

A retrospective analysis of 19 patients who had pulmonary artery bleeding during uniportal thoracoscopic lobectomy in which one group had undergone preventive pulmonary artery clamping, the clamping group (n = 11), and one group which did not receive preventive clamping, the non-clamping group (n = 8). We compared the rates of conversion from the uniportal VATS approach to open thoracotomy or multi-incision operation, duration of pulmonary artery repair, blood loss, length of postoperative hospital stay and postoperative complications of the two groups.

Results

Compared to the non-clamping group, the clamping group had lower rates of conversion to open thoracotomy (0% vs 62.5%, p < 0.05) and lower rates of conversion to multi-incision operations (18.2% of non-clamping converted to 2-port approach vs 12.5% of clamping converted to 2-port approach and 12.5% converted to 3-port approach, p < 0.05). Duration of pulmonary artery repair was reduced in the clamping group (10.1 ± 3.2 min vs 18.3 ± 5.5 min, p < 0.05). The clamping group also had decreased blood loss (23.6 ± 11.2 ml vs 47.5 ± 14.9 ml, p<0.05). There were no significant differences in postoperative hospital stay and postoperative complications between the two groups.

Conclusion

Pretreatment clamping of the pulmonary artery in VATS lobectomy can decrease conversion rates, decrease blood loss, shorten repairing time of the pulmonary artery, and feasibly can be applied in uniportal thoracoscopic lobectomy.

结论

在Ⅰ期至部分Ⅲa期肺癌病例中，单孔胸腔镜肺癌根治术安全可行。

A prospective study examining the impact of uniportal video-assisted thoracic surgery on the short-term quality of life in patients with lung cancer

Background

The aim of this study was to evaluate the effect of uniportal and three‐portal VATS in lung cancer patients on the postoperative short‐term quality of life (QOL).

Methods

A single‐center, prospective, nonrandomized study was performed on patients who underwent uniportal or three‐portal video‐assisted thoracoscopic surgery (VATS) lobectomy and systemic mediastinal lymph node dissection. QOL was measured before surgery at baseline and at one, two, four, and eight weeks after the operation. The measured data of normal distribution were indicated by the mean ± standard deviation, the independent sample t‐test was used among the groups, and the χ2 test was used to compare the counting. Non‐normal distribution of the measurement data was carried out using the Mann‐Whitney test.

Results

Preoperative functional areas, symptom areas and overall health scores were similar in the two groups. The physical, role, emotional and social functions and overall health status of the uniportal group were significantly higher than those of the three‐portal group in postoperative time. The score of symptom field was higher in one week after operation, the score of two, four and eight weeks decreased gradually, but it was still above the preoperative level, and the fatigue and pain of the uniportal group were significantly lower than that of the three‐portal group.

Conclusion

The advantages of uniportal VATS include a shorter hospital stay, more rapid recovery and superior cosmetic results compared to three‐portal VATS. Additionally, uniportal VATS is superior to three‐portal thoracoscopic surgery in terms of the immediate postoperative short‐term QOL.

Medical thoracoscopic cryoevacuation: A novel technique to manage retained hemothorax

Hemothorax is an important complication of blunt trauma chest. The presentation may be delayed, especially in elderly patients with multiple rib fractures. Delayed presentation can be associated with retained hemothorax where a simple chest drain is often insufficient to evacuate the pleural cavity. Video-assisted thoracoscopy surgery is often used to manage such patients in a minimally invasive manner. Here, we demonstrate a novel application of flexi-rigid thoracoscopy with CryoProbe^® for evacuation of retained hemothorax in an elderly woman through a subcentimeter incision.

Comparison of single utility port video-assisted thoracoscopic surgery (VATS) and three-port VATS for non-small cell lung cancer

Clinical efficacy of single utility port video-assisted thoracoscopic surgery (VATS) and three-port VATS for patients with non-small cell lung cancer (NSCLC) was compared. A total of 156 patients with NSCLC who underwent VATS in Taizhou Hospital of Zhejiang Province from July 2015 to January 2017 were selected as subjects. They were randomly divided into group A (n=74) and group B (n=82), in which group A was treated with single utility port VATS and group B was treated with three-port VATS. Perioperative indicators such as operation time, intraoperative blood loss, postoperative drainage, removal of drainage tube, lymph node dissection, hospitalization time, postoperative complications, postoperative pain and postoperative quality of life were observed. Expression levels of CRP and IL-6 in serum were detected by enzyme-linked immunosorbent assay (ELISA). There was no significant difference in the operation time, postoperative drainage volume, drainage tube removal time and lymph node dissection between groups A and B (P>0.05). Blood loss and hospitalization time in group A were significantly lower than those in group B (P<0.001). VAS scores at 1–3 days after operation in group A were significantly lower than those in group B (P<0.001). Levels of serum CRP and IL-6 at 1–7 days after operation in group A were significantly lower than those in group B (P<0.001). Incidence of complication in group A was not significantly different from that in group B (P>0.05). Overall quality of life scores of group A and B were significantly lower than the preoperative scores (P<0.001). Overall status score of group A was significantly higher than that of group B (P<0.001). Clinical efficacies of single utility port VATS and three-port VATS were similar. Single utility port VATS can reduce trauma during surgery, reduce stress response, relieve postoperative pain, and facilitate the recovery of postoperative quality of life.

[A Comparative Study of Acute and Chronic Pain between Single Port and Triple Port Video-assisted Thoracic Surgery for Lung Cancer]

BACKGROUND

Through the comparative analysis of the acute and chronic pain postoperative between the single port and triple port video-assisted thoracic surgery to seek the better method which can reduce the incidence of acute and chronic pain in patients with lung cancer.

METHODS

Data of 232 patients who underwent single port -VATS (n=131) or triple port VATS (n=101) for non-small cell lung cancer (NSCLC) on January 1, 2016 to June 30, 2017 in our hospital were analyzed. The clinical and operative data were assessed, numeric rating scale (NRS) was used to evaluate the mean pain score on the 1th, 2th, 3th, 7th, 14th days, 3th months and 6th months postoperative.

RESULTS

Both groups were similar in clinical characteristics, there were no perioperative death in two groups. In the 1th, 2th, 7th, 14th days and 3th, 6th months postoperative, the NRS score of the single port group was superior, and the difference was significant compared with the triple port (P<0.05). There was no statistically significant difference between the two groups in operative time, blood loss, postoperative hospitalization time, duration of chest tube, the NRS scores in the 3 d (P>0.05). Univariate and multivariate analysis of the occurrence on the chronic pain showed that the operation time, surgical procedure and the 14th NRS score were risk factors for chronic pain (P<0.05).

CONCLUSIONS

The single port thoracoscopic surgery has an advantage in the incidence of acute and chronic pain in patients with non-small cell lung cancer. Shorter operative time can reduce the occurrence of chronic pain. The 14th day NRS score is a risk factor for chronic pain postoperative.

The acceptance of illness, the intensity of pain and the quality of life in patients with lung cancer

Background

Lung cancer is the major cause of cancer related deaths worldwide. The overall 5-year survival rate is very low and accounts for only 15%. Poor quality of life is considered a prognostic factor for shorter survival in lung cancer patients. The aim of the study was to examine the relationships between pain, the acceptance of illness and quality of life in patients with lung cancer.

Methods

The study included 155 patients with lung cancer with mean age of 62.23 [standard deviation (SD)=9.86] years. We used the Acceptance of Illness Scale (AIS) and the Visual Analog Scale (VAS) for pain, and the Short Form Health Survey (SF-8) for the assessment of quality of life. For statistical analysis, Spearman's rank correlation coefficient and linear regression method were used.

Results

Mean score of the acceptance of illness was 27.1 (SD=9.2). Mean score of the pain severity as measured by the VAS was 4.07 (SD=1.83). The acceptance of illness was significantly positively correlated with all the domains of quality of life. Both the AIS and the VAS were independent determinants of physical and mental components of quality of life. Age and World Health Organization (WHO) performance status were additional predictors of physical component of quality of life.

Conclusions

The knowledge about the acceptance of illness, consequences of the decreased acceptance of illness, and factors affecting its level in patients with lung cancer is still insufficient. Relationships among acceptance of illness, quality of life, and pain should be further investigated.

Non-intubated single-incision video-assisted thoracic surgery: a two-center cohort of 188 patients

BACKGROUND

Non-intubated single-incision procedures are slowly expanding because of high experience and skill required, and stricter selection criteria. The aim of this study is to present the first retrospective two-center series in Taiwan and Spain.

METHODS

We performed a retrospective analysis of 188 patients undergoing non-intubated single-incision video-assisted thoracic surgery (NI-SI-VATS) procedures between July 2013 to November 2015 in two centers in Taiwan (170 patients) and Spain (18 patients) with two different anesthetic methods. Demographic data, clinicopathological features, preoperative tests, and final outcomes were analyzed to compare the outcomes with the two different techniques.

RESULTS

Of the 188 patients, 147 (78%) were women, with a mean body mass index (BMI) of 22.7. Of the 196 specimens, 145 (74%) were malignancies with a mean size of 9.7 mm. Wedge resection was performed in 172 patients (91.4%), anatomical segmentectomy with lymphadenectomy in 8 (4.7%), and lobectomy with lymphadenectomy in 5 (2.6%). Three patients (1.6%) required conversion to orotracheal intubation, while 5 patients (2.7%) required additional ports. Complications appeared in 16 patients (8.5%) with air leak as the most frequent in 7 cases (3.7%). Median chest drainage was 1 day, and median postoperative stay was 3 days. There was neither perioperative death nor postoperative readmission.

CONCLUSIONS

Non-intubated single-incision procedures can be feasible and safe in expert hands and experienced teams, even for anatomical resections. Strict selection criteria, skill and experience are mandatory. Comparative cohorts and randomized trials are needed.

Uniportal video-assisted thoracic surgery for major lung resections: pitfalls, tips and tricks

Nearly six years since inception, uniportal video-assisted thoracic surgery (VATS) has become a growing part of major lung resections and has revolutionized the way thoracic surgeons treat pulmonary lesions. This technique is being touted for various benefits. It ensures direct visualization together with a better exposure of the lung and allows the chance of a digital palpation of the lesion through a small incision. Postoperative pain is reduced due to the involvement of only one intercostal space without rib spreading and muscle disruption. The comfort and aesthetics factors are improved significantly since the oncological principles and radicality of open surgery are restored. As the surgeons gain more experience in uniportal-VATS lobectomy, more complex cases can be managed by this technique. The objectives of this work are to set the basic steps for performing major lung resections (lobectomy, bilobectomy and pneumonectomy) by utilizing uniportal-VATS and to analyze some common pitfalls that thoracic surgeons face when practicing this technique and provide practical tips and tricks on how to avoid.

[Development, Application Details, and Prospects of Uni-VATS on Lung Cancer Radical Operation under the Concept of "Precise Medical Treatment"]

单孔电视胸腔镜手术（uni-portal uideo-assisted thoracic surgery, Uni-VATS）的推广，是近年微创胸外科最重大的进展之一。随着腔镜下成像设备、切割缝合器械及电分离器械的改进，单孔VATS的应用范围已从最初的肺组织活检术逐渐扩大到解剖性肺叶/段切除、全肺切除、支气管/血管袖式吻合。多中心大量报道已证实：单孔VATS行肺叶切除安全、可行，清扫纵隔淋巴结的组数及总数均不低于传统多孔VATS，在疼痛、创伤及术后恢复方面也有积极的结果。虽然暂未得到多中心、大样本的临床数据如5年生存率，但有序地逐步开展单孔VATS仍是微创胸外科未来发展的重要方向。本文将围绕单孔VATS的原理及具体操作细节，结合肺癌根治术的基本操作理念进行讨论及综述，以期为单孔VATS的有序、规范化开展提出思考和探索。
