Objective To compare the differences between the up-lobectomy by single-microport assisted micro-uni-port thoracoscopy surgery and traditional uni-portal video assisted thoracic surgery, summarize and analyze the technical points of single-microport assisted micro-uni-port thoracoscopy surgery, and explore the surgical effect and value of promotion. Methods We retrospectively analyzed the clinical data of patients who underwent radical upper lobectomy at the Thoracic Surgery Department of Xi’an International Medical Center Hospital from March 2023 to June 2024. The patients were divided into two groups according the surgical procedure: a single-micromini-assisted group (patients underwent up-lobectomy by single-microport assisted micro-uni-port thoracoscopy) and a traditional uniportal group (patients underwent traditional uniportal thoracoscopic lobectomy). Clinical outcomes were compared between the two groups. Results We finally included 62 patients. There were 30 patients with 16 males and 14 females at an average of 57.4±10.8 years in the the single-micromini-assisted group and 32 patients with 20 males and 12 females at an average age of 57.6±8.7 years in the traditional uni-port thoracoscopy group. Both groups successfully completed minimally invasive surgery.The baseline data were consistent between the two groups. The operation time was shorter in the single microport assisted group [(146.03±30.79) min vs. (171.41±36.41) min, P=0.004] than that in the traditional uni-port thoracoscopy group with a statistical difference. There was no statistical difference between the two groups in terms of intraoperative blood loss, postoperative pain score, dissected lymph node number, postoperative drainage volume, postoperative tube time, postoperative hospital stay, hospitalization cost, or the incidence of postoperative complications (P>0.05). Conclusion Single-microport assisted micro-uni-port thoracoscopy surgery can maximize the advantages of three-portal and uni-portal VATS, and effectively avoid the disadvantages of three-portal and uni-portal VATS, which can significantly shorten the operation time, without increasing the postoperative pain and complications, is a more minimally invasive, safer and more convenient surgical method.
ObjectiveTo compare the efficacy and safety of video-assisted thoracoscopic surgery (VATS) thymectomy for the treatment of thymoma through subxiphoid uniportal approach using double sternum retractors, and subxiphoid and subcostal arch approach. Methods We retrospectively analyzed the clinical data of the patients diagnosed with thymoma who underwent VATS thymectomy from June 2023 to June 2024 in West China Hospital. Patients were categorized based on the surgical approach into two groups: a subxiphoid uniportal VATS thymectomy (SUVT) group and a subxiphoid and subcostal arch VATS thymectomy (SASAT) group. Comparisons were made between the two groups regarding surgical duration, intraoperative blood loss, postoperative drainage, thymoma size and location, and postoperative pain assessed using the visual analogue scale (VAS). ResultsThe SUVT group consisted of 20 patients, including 11 males and 9 females, with an average age of (51.5±14.3) years. The SASAT group comprised 40 patients, including 26 males and 14 females, with an average age of (50.0±13.0) years. Compared to the SASAT group, the SUVT group had significantly larger thymomas [ (5.9±2.7) cm vs. (4.2±2.1) cm, P=0.010] and a higher proportion of neoplasms located in the superior mediastinum (30.0% vs. 2.5%, P=0.007). Additionally, the VAS pain scores on postoperative days 3, 7, and 30 were significantly lower in the SUVT group compared to the SASAT group (P<0.05). There were no statistical differences between the two groups in demographic characteristics, operative time, intraoperative blood loss, duration and volume of postoperative drainage, length of postoperative hospital stay, or the VAS pain score on the first postoperative day. Conclusion SUVT using double sternum retractors significantly reduces postoperative pain and provides superior efficacy in the resection of larger thymomas or those situated in the superior mediastinum.
ObjectiveTo investigate the effect of multi-sided foramen ultrafine drainage tube with metal support on the formation of thoracic residual cavity after uniportal video-assisted thoracoscopic (VATS) upper lobectomy. MethodsThe clinical data of the patients who underwent uniportal VATS upper lobectomy for lung cancer in the Department of Thoracic Surgery of the First Hospital of Lanzhou University from January 2021 to April 2022 were retrospectively analyzed. According to the type of ultrafine drainage tube used in the surgery, the patients were divided into a test group (using metal-supported multi-sided foramen ultrafine drainage tube) and a control group (using ordinary 12F ultrafine drainage tube). The incidence of postoperative thoracic residual cavity and operation-related data were compared between the two groups. ResultsA total of 200 patients were enrolled, including 126 males and 74 females, with a mean age of 57.52 years. There were 90 patients in the test group, and 110 patients in the control group. The incidence of postoperative thoracic residual cavity in the test group was lower than that in the control group (P=0.045). The differences in the postoperative bedtime, postoperative visual analogue scale, postoperative analgesic pump using time, postoperative hospitalization time, times of postoperative thoracentration and drainage, postoperative drainage time and hospitalization cost between the two groups were statistically significant (P<0.05). The incidences of postoperative lung infection, pleural effusion and atelectasis complications were lower in the test group than those in the control group (P<0.05). The differences in the preoperative anesthesia time, operation time, intraoperative bleeding and postoperative lung leakage were not statistically significant (P>0.05). ConclusionThe use of multi-sided foramen ultrafine drainage tube with metal support can reduce the incidence of thoracic residual cavity after uniportal VATS upper lobectomy, and can reduce pain and economical burdens and the incidence of operation-related complications, accelerating the recovery of patients after surgery. The application of multi-sided foramen ultrafine drainage tube with metal support in uniportal VATS upper lobectomy can be widely used in the clinic.
ObjectiveTo compare the perioperative efficacy and safety of robot-assisted thoracoscopic surgery (RATS) and uniportal video-assisted thoracoscopic surgery (UVATS) in the lobectomy for early lung adenocarcinoma.MethodsClinical data of 70 early lung adenocarcinoma patients, receiving RATS or UVATS lobectomy by the same surgical team in our hospital from November 2018 to May 2020 were retrospectively analyzed. There were 24 males and 46 females with an average age of 59.3±8.9 years. According to different surgical methods, the patients were divided into a RATS group (31 patients) and a UVATS group (39 patients). The operation time, intraoperative blood loss, postoperative hospital stay, indwelling time, drainage volume, number of lymph node dissected, stations of lymph node dissected and perioperative complications were compared between the two groups.ResultsThere was no conversion to thoracotomy or perioperative death in both groups. There was no significant difference in intraoperative blood loss, postoperative hospital stay, indwelling time of thoracic drainage tube, thoracic drainage volume or stations of lymph node dissected between the two groups (P>0.05). There was no significant difference in the incidence of pulmonary infection, persistent lung leakage, chylothorax, arrhythmia or overall complications between the two groups (P>0.05). The operation time of the RATS group was longer than that of the UVATS group (195.8±52.8 min vs. 154.0±43.1 min, P=0.001). The number of lymph node dissected in the RATS group was more than that of the UVATS group (P=0.016).ConclusionBoth RATS and UVATS are safe and feasible in the treatment of lung cancer. The number of lymph nodes removed by RATS is significantly more than that of UVATS.
ObjectiveTo investigate the effectiveness of sublobar resection and lobectomy via uniportal video-assisted thoracoscopic surgery (U-VATS) for lung metastases from colorectal cancer.MethodsRetrospective research was conducted on 42 colorectal cancer patients with lung metastases who underwent U-VATS sublobar resection and lobectomy at the Tongji Hospital, Huazhong University of Science and Technology between April 2016 and May 2019, including 24 males and 18 females with an average age of 58.0±9.9 years. Among them 17 patients received U-VATS sublobar resection and 25 patients received lobectomy. The operation time, intraoperative blood loss, postoperative pulmonary infection, drainage tube indwelling time, drainage volume on the first day after surgery, postoperative hospital stay were analyzed between the two groups, and the relationship between the prognosis and clinical characteristics of the two groups was compared.ResultsSublobar resection patients had less lung metastases (P=0.043) and shorter operation time (P=0.023) compared with the lobectomy patients. There was no significant difference between the lobectomy and sublobar resection groups in intraoperative blood loss (P=0.169), rate of postoperative infection (P=0.982), postoperative drainage duration (P=0.265), drainage volume on the first day after surgery (P=0.402) and postoperative hospital stay (P=0.612). The progression-free survival of the two groups was 25.19 months and 23.63 months (P=0.721), and their overall survival was 29.09 months and 30.64 months (P=0.554).ConclusionConsidering guantity and locations of lung metastases, U-VATS sublobar resection can achieve a similar prognosis to lobectomy for lung metastases from colorectal cancer. Further efficacy of this surgical strategy remains to be proved by longer follow-up.
ObjectiveTo investigate the efficacy of uniportal video-assisted thoracoscopic surgery (VATS) anatomic basal segmentectomy.MethodsThe clinical data of 15 patients who underwent uniportal VATS anatomic basal segmentectomy between June 2020 and December 2020 were retrospectively reviewed. There were 4 males and 11 females with a median age of 53 (32-70) years. The incisions were placed in the fifth intercostal space across the mid-axillary line. All basal segmentectomies were performed through the interlobar fissure or inferior pulmonary ligament approach following the strategies of single-direction and stem-branch.ResultsAll patients underwent basal segmentectomy successfully with no conversion to multi-portal procedure or thoracotomy. The median operation time was 120 (90-160) min, median intraoperative blood loss was 20 (10-50) mL, median drainage time was 3 (2-5) d, and median postoperative hospital stay was 4 (4-10) d. The maximum diameter of the lesion in the resected basal segment was 1.2 (0.7-1.9) cm. The median resected lymph nodes were 7 (5-12). There was no evidence of nodal metastases. One patient suffered postoperative atelectasis and subsequent pneumonia. No perioperative death occurred.ConclusionUniportal VATS anatomic basal segmentectomy is feasible and safe. It can be performed in a simple manner following the strategy of single-direction.
With the development of precision diagnosis and treatment of lung cancer, anatomical segmentectomy has become an important surgical procedure for the treatment of early-stage lung cancer. After the widespread popularization of video-assisted thoracoscopic surgery (VATS), the treatment of lung cancer has entered the era of minimally invasive surgery. Since it was first reported in 2012, uniportal video-assisted anatomical segmentectomy has gained increasing clinical application. Uniportal VATS is less invasive than thoracotomy and traditional VATS. At present, the main research hotspots around uniportal video-assisted anatomical segmentectomy include specific indications, short-term and long-term efficacy, and learning curve. This article will introduce the characteristics, indications and surgical techniques of this procedure, then summarize and discuss the latest research progress of uniportal video-assisted anatomical segmentectomy based on the latest evidence-based evidence.
Objective To compare the effectiveness of unilateral biportal endoscopy (UBE) technique with the interlaminar uniportal endoscopy (IUE) technique for the treatment of L5, S1 lumbar disc herniation. MethodsThe clinical data of 69 patients with L5, S1 lumbar disc herniation who met the selection criteria between January 2020 and December 2020 were retrospectively analysed. The patients were divided into UBE group (30 cases) and IUE group (39 cases) according to endoscopic surgical technique. The general data, such as gender, age, body mass index, disease duration, and preoperative visual analogue scale (VAS) scores of low back/leg pain and Oswestry disability index (ODI), was not significantly different between the two groups (P>0.05). Perioperative outcomes [estimated blood loss (EBL), total operation time, extracanal operation time, intracanal decompression time, intraoperative radiation exposure dose, incision length, operative related complications, and postoperative hospitalization stay] and clinical outcomes (VAS score of low back/leg pain before operation and at 3 days, 3 months, 6 months, and 12 months after operation as well as the ODI before operation and at 3 months, 6 months, and 12 months after operation) were recorded and compared between the two groups. ResultsAll patients completed the surgery successfully. The incision length, EBL, and extracanal operation time in UBE group were significantly longer than those in IUE group (P<0.05), and the intracanal decompression time in UBE group was significantly shorter than that in IUE group (P<0.05). There was no significant difference in the total operation time, intraoperative radiation exposure dose, and postoperative hospitalization stay between the two groups (P>0.05). Patients in both groups were followed up 12-15 months (mean, 13.3 months). Dural tear ocurred in 1 patient of the UBE group, and recurrence ocurred in 1 patient of the IUE group, the others of both groups had no surgery-related complications and recovered well after operation. The VAS scores of low back/leg pain and ODI in both groups at each time point after operation significantly improved when compared with those before operation (P<0.05); there was no significant difference in VAS scores and ODI at each time point after operation between two groups (P>0.05). ConclusionThe effectiveness of UBE technique in the treatment of L5, S1 lumbar disc herniation is similar to that of IUE technique, and the efficiency of intraspinal operation is better than that of IUE technique. Although UBE technique is inferior to IUE technique in terms of surgical trauma, there is no significant difference in postoperative recovery between the two techniques.
With the ongoing evolution of minimally invasive thoracic surgery techniques, innovative anatomical approaches facilitating rapid perioperative recovery while achieving optimal aesthetic results and pain-free outcomes have become a pivotal direction in pulmonary resection. While periareolar incisions have demonstrated well-established advantages in cosmetic preservation and pain management in breast and thyroid procedures, the standardization of this approach for video-assisted thoracoscopic pulmonary resection requires further refinement. This consensus synthesizes the collective expertise of China's leading thoracic surgery centers in periareolar approach pulmonary resections. It aims to establish comprehensive clinical consensus that encompasses prerequisite surgical criteria, standardized perioperative management protocols, technically optimized operative procedures, and evidence-based complication prevention and management strategies, ultimately providing guidance for the standardized application of this innovative surgical technique.
ObjectiveTo investigate the effects of subxiphoid uniportal video-assisted thoracoscopic surgery (SUVATS) and intercostal uniportal VATS (IUVATS) in lobectomy for non-small cell lung cancer (NSCLC).MethodsA total of 428 patients with NSCLC who underwent lobectomy via SUVATS or IUVATS from July 1st to 31st, 2019 in Shanghai Pulmonary Hospital were enrolled. Patient characteristics, perioperative outcomes and postoperative pain scores at different time points were collected. The patients were divided into a SUVATS group (80 patients, 42 males and 38 females with an average age of 58.8±9.6 years) and an IUVATS group (348 patients, 161 males and 187 females, with an average age of 61.2±10.0 years). The clinical effectiveness of the two groups was compared.ResultsThere was no significant difference in sex (P=0.314), age (P=0.052), preoperative pulmonary function (P=0.701), combined chronic comorbidities (chronic cardiovascular disease, P=0.775; chronic obstructive pulmonary disease, P=0.678) and postoperative pathology (P=0.132) between the two groups. Compared with the IUVATS group, patients in the SUVATS group had longer operation time (155.6±34.4 min vs. 141.3±27.0 min, P<0.001), less intraoperative blood loss (165.2±160.6 mL vs. 223.7±272.4 mL, P<0.001), shorter time of chest tube use (4.3±2.0 d vs. 4.9±1.9 d, P=0.011) and less postoperative pain score at different time points (postoperative 8 h, P<0.001; postoperative day 1, P=0.019; postoperative day 2, P=0.015; the day before discharge, P<0.001).ConclusionSUVATS is a safe and effective technique for lobectomy in NSCLC patients with less postoperative pain and can promote postoperative recovery.
