ObjectiveTo investigate the safety and feasibility of thoracoscopic lobectomy without mechanical suture.MethodsThe data of 28 consecutive patients (a non-mechanical suture group, 16 males and 12 females at age of 61.23±11.10 years) who underwent non-mechanical suture anatomic thoracoscopic lobectomy performed by the same surgeon from March 2015 to March 2018 were analyzed retrospectively, and 28 patients (18 males and 10 females at age of 59.45±13.39 years) who underwent completely anatomic thoracoscopic lobectomy with endoscopic stapler (a mechanical suture group) in the same period were matched. The clinical effectiveness of the two groups was compared.ResultsThe operation time between the non-mechanical suture group (136.30±53.46 min) and the mechanical suture group (109.63±44.61 min) showed a statistical difference (P<0.05). While in term of intraoperative bleeding volume (65.00 ml vs. 50.00 ml), postoperative thoracic drainage time (3.73 days vs. 3.56 days), thoracic drainage volume (538.60 ml vs. 563.70 ml), postoperative hospital stay (5.58 days vs. 5.35 days) and postoperative complication rate (5/28 vs. 6/28), there was no statistical difference between the two groups. Hospitalization expense was significantly different between the two groups (35 438.30 yuan vs. 51 693.60 yuan).ConclusionNon-mechanical suture thoracoscopic anatomic lobectomy is safe and feasible, and can significantly reduce the medical cost but prolong the operation time.
ObjectiveTo explore clinical strategies of early diagnosis and treatment of solitary pulmonary nodules (SPN), and define the importance of biological tumor markers, preoperative CT-guided localization with the combination of methylene blue and hookwire system, and video-assisted thoracoscopic surgery (VATS)for early diagnosis and treatment of SPN. MethodsWe retrospectively analyzed clinical records of 70 SPN patients in Department of Thoracic Surgery of Taixing People's Hospital from January 2011 to February 2014. There were 33 male and 37 female patients with their age of 32-87 (59.74±2.04)years. Preoperatively, patients' medical history, heart, lung, liver and kidney function, sputum cytology and bronchoscopic biopsy results were combined with biological tumor markers to make a preliminary differential diagnosis between benign or malignant SPN and surgical risk evaluation. For SPN less than 1 cm or too small for accurate intraoperative localization, CT-guided localization with the combination of methylene blue and hookwire system was routinely performed half an hour before the operation. For SPN large enough for accurate intraoperative localization, wedge resection of SPN and surrounding lung tissue was directly performed with VATS. Intraoperative frozen-section examination of resected lung specimens was preformed. If the pathological diagnosis was malignant, conventional VATS lobectomy/segmentectomy and lymphadenectomy were performed. If the pathological diagnosis was benign, the operation was then completed. Long-term follow-up was performed for SPN patients, especially patients with early-stage lung cancer. ResultsThere was no in-hospital death or postoperative bronchopleural fistula in this study. Postoperatively, there were 2 patients with pneumonia, 3 patients with pneumothorax and 1 patient with wound infection, who were all cured or improved after proper treatment. Among the 70 patients, 11 patients acquired pathological diagnosis via preoperative lung needle biopsy. Among the other 59 patients, 12 patients with eccentric SPN acquired pathological diagnosis via intraoperative biopsy, and 47 patients underwent SPN resection with VATS. Pathological diagnosis included adenocarcinoma in 19 patients, squamous cell carcinoma in 9 patients, bronchioloalveolar carcinoma in 3 patients, adenosquamous carcinoma in 2 patients, inflammatory pseudotumor in 11 patients, tuberculoma in 4 patients, granuloma in 5 patients, sclerosing hemangioma in 2 patients, lung metastasis from breast cancer in 1 patient, lung metastasis from colon cancer in 1 patient, lung metastasis from thyroid cancer in 1 patient, and lung metastasis from stomach cancer in 1 patient. All the 70 patients (100%)were followed up for a mean duration of 2-34 months, and there was no late death during follow-up. One patient with adenocarcinoma of the right upper lobe had cerebral metastasis 18 months after operation, and had been receiving radiotherapy. All the other patients had a good quality of life. ConclusionAbove clinical strategies are accurate for early diagnosis and minimally invasive treatment of SPN with good postoperative recovery and short-term outcomes.
Objective To evaluate the efficacy and safety of total thoracoscopic lobectomy for patients with stage Ⅰ/Ⅱ non-small cell lung cancer (NSCLC). Methods The clinical data of 138 NSCLC patients from January 2013 to June 2015 in Shaanxi People's Hospital were retrospectively analyzed. There were 88 males and 50 females with an average age of 57.4±8.8 years, ranging from 44 to 76 years. According to the operation methods, they were divided into a video-assisted thoracoscopic surgery (VATS) group (thoracoscopic lobectomy in 63 cases) and a thoracotomy group (conventional open chest surgery in 75 cases). The intra- and postoperative clinical data, surgical complications and pulmonary function were compared. Results There was no significant difference in the operation time, intraoperative lymph node dissection groups, intraoperative lymph node dissection number between two groups (P>0.05). The blood loss, postoperative drainage volume, duration of postoperative analgesia, Numeric Rating Scale for pain and hospital stay in the VATS group were significantly lower than those of the thoracotomy group (P<0.05). The pre- and postoperative FVC%pred and FEV1%pred in both groups were compared and there was no significant difference (P>0.05). However the postoperative FVC%pred and FEV1%pred in both groups significantly reduced compared with preoperative ones (P<0.05). Complication rate of thoracoscopic group was significantly less than that of the thoracotomy group (20.63%vs. 32.00%,χ2=3.974,P=0.046). Conclusion Thoracoscopic lobectomy for NSCLCⅠ/Ⅱpatients is reliable, and achieves rapid postoperative recovery as well as less complications.
Abstract： Objective To investigate strategies for prevention，early diagnosis，and prompt treatment for acute pulmonary embolism（PE）after video-assisted thoracoscopic surgery（VATS）lobectomy. Methods From January 2007 to November 2010, 1 115 patients with lung cancer underwent VATS lobectomy in the First Affiliated Hospital of Guangzhou Medical College. Among them, 13 patients had acute PE postoperatively, including 6 male patients and 7 female patients with their mean age of 62.3 years（ranging from 42 to 73 years）.All the patients were diagnosed by spiral CT pulmonary artery angiography（SCTPA）, and received anticoagulation therapy with low molecular weight heparin and warfarin. Results The incidence of acute PE after VATS lobectomy was 1.17%（13/1 115）, and the patients with low PE-related early mortality risk accounted for a large proportion（11/13）. There were 12 patients with right-side PE. All the patients’ signs and symptoms were significantly alleviated after administration of anticoagulation therapy. Nine patients received SCTPA review after treatment which showed that their PE had disappeared or been significantly absorbed. No hematological complications including thoracic hemorrhage or wound errhysis occurred after treatment. All surviving patients were followed up for 1 month to 3 months. During follow-up, these patients were alive without PE recurrence. Conclusion SCTPA is the first-choice examination for the diagnosis of acute PE after VATS lobectomy. Prophylaxis against PE and prompt treatment are necessary depending on individual manifestations. VATS lobectomy should be favored as a minimally invasive surgical treatment for patients with lung cancer, for the low incidence of postoperative PE and low PE-related early mortality risk.
Mini-invasive video-assisted thoracoscopic surgery (VATS) has been employed in diagnosis and treatment of esophageal diseases for about 10 years. The potential advantages of VATS over thoracotomy are reduction of chest pain just after the operation and in the long run, lower incidence of postoperative respiratory complications, and reduction of aesthetic sequelae. Thoracoscopic staging of esophageal cancer is to evaluate the invasion and metastasis of cancer, which is helpful for better selection of patients for appropriate treatment .Operation of esophageal cancer with VATS is prescribed mainly in the early stage of carcinoma, but it’s application is restricted due to the multiple sites of operation and complexity of procedures. VATS for benign esophageal diseases such as esophageal leiomyoma and achalasia is becoming the preferable choice of operation in qualified medical centers.
Abstract：?Objective?To evaluate clinical outcomes of single utility port complete video-assisted thoracoscopic surgery （VATS） lobectomy for patients with early-stage lung cancer.?Methods?We retrospectively analyzed the clinical data of 162 consecutive patients with early-stage lung cancer who underwent single utility port complete VATS lobectomy from September 2009 to October 2011 in Chinese PLA General Hospital （single utility port group），and compared them with 221 patients with early-stage lung cancer who underwent video-assisted mini-thoracotomy （VAMT） lobectomy in the same period （VAMT group）. The clinical outcomes including operation time, intraoperative blood loss, lymph node dissection number, time to first activity out of bed, chest drainage duration and postoperative complications, were compared between the two groups.?Results?No perioperative death was observed in both groups. There were statistical differences in the intraoperative blood loss （162.8±75.6 ml vs. 231.4±62.8 ml）, time to first activity out of bed （2.2±0.3 d vs. 3.7±0.5 d） , and chest drainage duration （3.5±0.2 d vs. 4.6±0.4 d） between the two groups （P＜0.05）. There was no statistical difference in operation time （133.7±22.0 min vs. 124.9±25.7 min） , lymph node dissection number （11.7±1.9 vs. 12.5±2.7）， and incidence of serious postoperative complications （7.4% vs. 8.1%）between the two groups.?Conclusion?Single utility port complete VATS lobectomy and lymph node dissection are safe and reliable for patients with early-stage lung cancer with less injury and better postoperative recovery compared with VAMT.
Objective To systematically evaluate the difference in clinical outcomes between subxiphoid video-assisted thoracoscopic surgery (SVATS) and intercostal video-assisted thoracoscopic surgery (IVATS) for anterior mediastinal tumor resection. Methods Online databases including The Cochrane Library, PubMed, EMbase, Web of Science, Sinomed, CNKI, Wanfang from inception to December 19, 2022 were searched by two researchers independently for literature comparing the clinical efficacy of SVATS and IVATS in treating anterior mediastinal tumors. Two researchers independently screened literature and extracted relevant data. The quality of the included literature was evaluated using the Newcastle-Ottawa Scale (NOS). The meta-analysis was performed by RevMan 5.3. ResultsA total of 12 studies with 1 517 patients were enrolled. NOS score≥6 points. The results of meta-analysis showed that compared with the IVATS, SVATS had less blood loss (MD=?17.76, 95%CI ?34.21 to ?1.31, P=0.030), less total postoperative drainage volume (MD=?70.46, 95%CI ?118.88 to ?22.03, P=0.004), shorter duration of postoperative drainage tube retention (MD=?0.84, 95%CI ?1.57 to ?0.10, P=0.030), lower rate of postoperative lung infections (OR=0.33, 95%CI 0.16 to 0.70, P=0.004), lower postoperative 24 h VAS pain score (MD=?1.95, 95%CI ?2.64 to ?1.25, P＜0.001) and 72 h VAS pain score (MD=?1.76, 95%CI ?2.55 to ?0.97, P＜0.001), and shorter postoperative hospital stay (MD=?1.12, 95%CI ?1.80 to ?0.45, P=0.001). There was no statistical difference in the operation time, the incidence of postoperative complications, incidence of postoperative phrenic nerve palsy or incidence of postoperative arrhythmia (P＞0.05). ConclusionSVATS for the treatment of anterior mediastinal tumors has high safety. Compared with the IVATS, the patients have less intraoperative blood loss and postoperative drainage volume, lower risk of postoperative pulmonary infection, less postoperative short-term pain, and shorter postoperative catheter duration and hospital stay, which is more conducive to rapid postoperative recovery.
Surgery has played an important role in treating non-small cell lung cancer (NSCLC). Resection is usually the first choice for NSCLC patients in stage Ⅰ and stage Ⅱ, and it is also an important part of the comprehensive treatment for the stage ⅢA patients. Standard surgery of NSCLC includes resection of the primary tumor lesion and swee-ping of ipsilateral lymph nodes and mediastinal lymph nodes. The goal of treatment for lung cancer in early stage aims to decrease the rate of recurrence and mortality. In recent years, video-assisted thoracoscopic surgery and da Vinci robotic minimal invasive surgery have made gratifying achievements, especially for small peripheral lung nodules surgery. For patients with NSCLC at stage ⅢA, the central focus of research is about identifying patients who will benefit in the surgery combining with chemotherapy and radiotherapy, therefore to choose the appropriate surgery.
ObjectiveTo determine postoperative pain of the robotic technique for the patients with lobectomy. MethodsWe retrospectively analyzed the clinical data of 120 patients with lobectomy between October 2014 and May 2015 in our hospital. The patients are divided into two groups:a robotic group, including 40 patients with 16 males and 24 females at age of 59.7±7.2 years, undergoing robotic lobectomy, and a video-assisted thoraciscopic surgery (VATS) lobectomy group (a VATS group) including 80 patients with 29 males and 51 females at age of 61.2±8.9 years, undergoing VATS lobectomy. We used the numerical rating scale (NRS) and verbal rating scale (VRS) to assess the pain level on the first day, the 7th day and the 30th day after the surgery. The pain level of the two groups was compared. ResultsThe patients in the two groups both felt pain. There were no statistical differences in the scores of VRS and NRS on the first day, the 7th day and the 30th day after the surgery between the two group (P>0.05). The pain score of the patients in the two groups decreased with no statistical difference from the first day to the 30th day after the surgery (P>0.05). ConclusionThe patients with robotic lobectomy have similar pain level after surgery compared with the patients with VATS lobectomy.
ObjectiveTo systematically review the efficacy and safety of single-port video-assisted thoracoscopic surgery (VATS) vs. multiple-port VATS in lobectomy for non-small cell lung cancer (NSCLC).MethodsThe PubMed, EMbase, the Cochrane Library, CBM, CNKI, Wanfang, VIP and Web of Science were searched to collect clinical studies about single- vs. multiple-port VATS for patients with NSCLC from inception to August 2018. The literatures were screened, data were extracted and the risk of bias of included studies was assessed independently by two reviewers. The meta-analysis with the collected data was performed by using RevMan 5.3 software.ResultsEleven studies (4 randomized controlled trials, 1 prospective cohort study and 6 retrospective cohort studies), including 1 574 patients. Among them, 779 patients were in the single-port group, and 795 in the multiple-port group. The results of meta-analysis showed that there was no significant difference between the two groups in the operation time (MD=3.60, 95%CI –8.59 to 15.79, P=0.56), the conversion rate (OR=1.06, 95%CI 0.54 to 2.06, P=0.87), the incidence of postoperative complications (OR=0.76, 95%CI 0.53 to 1.10, P=0.15), postoperative hospitalization time (MD=0.74, 95%CI –1.60 to 0.12, P=0.09), chest tube placement time (MD=0.63, 95%CI –1.28 to 0.02, P=0.06) or harvested lymph nodes (MD=–0.11, 95%CI –0.46 to 0.24, P=0.54). The intraoperative blood loss (MD=–17.12, 95%CI –31.16 to –3.08, P=0.02) was less in the single-port group than that in the multiple-port group. The visual analogue score (VAS) on postoperative first day (MD=–1.30, 95%CI –1.85 to –0.75, P<0.000 01) and on postoperative third day (MD=–0.82, 95%CI –1.00 to –0.65, P<0.000 01) were lower in the single-port group than those in the multiple-port group.ConclusionThe meta-analysis indicates that the efficacy of single-port VATS for NSCLC is equivalent to multiple-port VATS. However the intraoperative blood loss, the VAS scores on postoperative first and third days in the single-port group are better.
