Regardless of the cause of the chest wall defect, especially the extensive chest wall defect, if it cannot be effectively repaired and reconstructed, it may cause physiological and pathological changes such as chest wall softening, respiratory abnormalities and mediastinal oscillations. The main factors affecting the repair and reconstruction of the chest wall are the choice of reconstruction methods and materials. With the increasing understanding of chest wall defects, advances in reconstructive surgery techniques and the development of reconstructed materials, it has become possible to reconstruct many extensive chest wall defects that were previously impossible to complete. This article reviews the characteristics of chest wall defects, methods of repair, and current status and progress of reconstructed materials.
Esophageal carcinoma is one of the most common malignant tumor, a serious threat to human health. In the early and middle esophageal carcinoma patients, surgery is the only expected treatment to cure esophageal carcinoma. Traditional surgery of esophageal cancer needs thoracotomy and laparotomy, which has great trauma and high incidence of complications. So surgeons are looking for a minimally invasive surgical methods alternative to traditional esophagectomy. Video-mediastinoscopy is used to free middle and upper esophagus, as a minimally invasive surgical method, it is used in radical resection of esophageal cancer gradually. This article reviews the recent progress and the related research results in the application of mediastinoscopy in the radical resection of esophageal cancer. It is found that mediastinoscopy assisted the radical resection of esophageal cancer is a safe and feasible operation. It provides a feasible treatment option for early and middle stage esophageal cancer patients with pulmonary insufficiency who can not be resected by thoracoscopy.
The concept of enhanced recovery after surgery (ERAS) was firstly demonstrated in practice by the Danish scholar Henrik Kehlet in the early 2000s. At present, the ERAS concept has been widely used in a variety of surgical fields, but its application in esophageal cancer surgery is still limited. The new esophageal ERAS guidelines issued by ERAS Association bring new opportunities for the application and promotion of esophageal cancer surgery. Combined with the current situation of esophageal cancer surgery in China and related literature, in this paper we discuss the specific measures of ERAS concept in perioperative application of esophageal cancer in China.
ObjectiveTo compare the short-term and long-term effects of minimally invasive esophagectomy (MIE) and traditional open esophagectomy (OE) in patients with stage T1b esophageal squamous cell carcinoma (ESCC).MethodsWe retrospectively analyzed the clinical pathology data of 162 patients undergoing thoracic surgery at Northern Jiangsu People's Hospital from 2015 to 2018 whose pathological diagnosis was stage pT1b ESCC. According to the surgical approach, they were divided into MIE group and OE group. There were 55 males and 21 females in the OE group, with an average age of 63.3±5.6 years, and 60 males and 26 females in the MIE group, with an average age of 64.7±6.1 years. The preoperative, intraoperative and postoperative data of the two groups were compared and followed up. Survival data were compared using Kaplan-Meier and log-rank tests between the two groups, and Cox proportional hazard regression models were used to analyze prognostic factors.ResultsCompared with the OE group, the intraoperative bleeding volume of the MIE group was less (119.8±70.0 mL vs. 210.5±136.2 mL, P<0.001), and the lymph nodes dissected during the operation were more (19.1±7.4 vs. 13.8±5.9, P<0.001), the rate of postoperative pulmonary infections was lower (9.3% vs. 21.1%, P=0.036), but the operation time was longer (240.0±52.4 min vs. 179.5±35.7 min, P<0.001). Twenty-one patients had lymph node metastasis, and the lymph node metastasis rate was 13.0%. At the end of the follow-up, 19 patients died, and the overall survival (OS) at 1 year, 3 years, and 5 years after operation were 97.5%, 88.8% and 82.9%, respectively; 31 patients had recurrence and metastasis, and the disease-free survival (DFS) rate at 1 year, 3 years, and 5 years after operation was 95.1%, 80.9% and 75.6%. There was no significant difference in OS and DFS between the two groups. Multivariate Cox regression analysis of OS found that lymph node metastasis, anastomotic fistula and chylothorax were independent risk factors for OS. Multivariate Cox regression analysis of DFS found that lymph node metastasis, anastomotic fistula, chylothorax, and vascular cancer thrombus were independent risk factors for OS.ConclusionMIE can achieve the same long-term effects as OE, with less intraoperative bleeding, more lymph nodes dissected, and lower incidence of postoperative pulmonary infections, but it takes longer operation time.
ObjectiveTo compare the short- and long-term efficacy of surgery and endoscopy in the treatment of early esophageal cancer by a systematic review and meta-analysis.MethodsWe extracted data independently from The Cochrane Library, PubMed, EMbase, Web of Science for studies comparing surgery with endoscopy from 2010 to 2020. The primary outcomes including R0 resection rate, long-term overall survival (OS), disease-specific survival (DSS), major complications, recurrence, hospital stay and cost. Meta-analysis was performed using RevMan 5.3 and Engauge Digitizer was used to extract survival curves from relevant literature, and relevant data were calculated based on statistical methods. ResultsA total of 17 studies involving 3 705 patients were included. It was found that patients in the surgery group had a higher R0 resection rate compared with the endoscopic group (OR=0.13, 95%CI 0.07 to 0.27, P<0.001, I2=6%). The total complications rate of resection of esophageal cancer was higher than that of the endoscopic group (OR=0.28, 95%CI 0.16 to 0.50, P<0.001, I2=68%). The length of hospitalization in the endoscopic group was obviously shorter than that in the surgery group (MD=–8.28, 95%CI –12.44 to –4.13, P<0.001, I2=96%). The distant recurrence rate (OR=0.58, 95%CI 0.24 to 1.41, P=0.230, I2=0%) and the local recurrence rate after resection (OR=1.74, 95%CI 0.66 to 4.59, P=0.260, I2=40%) in the endoscopic group was similar to those of the surgery group. There was no significant difference in 5 year-OS rate between the two groups (HR=0.86, 95%CI 0.67 to 1.11, P=0.25, I2=0%), which was subdivided into two groups: adenocarcinoma (HR=0.55, 95%CI 0.15 to 2.05, P=0.37, I2=0%) and squamous cell carcinoma (HR=0.68, 95%CI 0.46 to 1.01, P=0.06, I2=0%), showing that there was no difference between the two subgroups. There was no significant difference in the DSS rate (HR=0.72, 95%CI 0.49 to 1.05, P=0.090, I2=0%) between the two groups. The cost of the surgery group was significantly higher than that of the endoscopic group (MD=–12.97, 95%CI –18.02 to –7.92, P<0.001, I2=93%).ConclusionThe evidence shows that endotherapy may be an effective treatment for early esophageal neoplasm when considering the long-term outcomes whether it is squamous or adenocarcinoma, even though it is not as effective as surgery in the short-term efficacy.
Objective To evaluate the security and clinical value of the combination of three-dimensional computed tomography-bronchography and angiography (3D-CTBA) and indocyanine green (ICG) staining in video-assisted thoracic surgery (VATS) segmentectomy. Methods The clinical data of 125 patients who received VATS segmentectomy from January 2020 to January 2021 in our hospital were retrospectively analyzed. There were 40 (32.0%) males and 85 (68.0%) females with an average age of 54.8±11.1 years. Results The procedure was almost identical to the preoperative simulation. All intersegment planes were displayed successfully by ICG reverse staining method. There was no allergic patient. A total of 130 pathological specimens were obtained from the 125 patients. The mean operation time was 126.8±41.9 min, the time of first appearance of fluorescence was 22.7±4.9 s, the mean mark time was 65.6±20.3 s, the median blood loss was 20.0 (10.0-400.0) mL, the postoperative hospital stay was 5.6 (4.0-28.0) d, and the postoperative retention of chest tube time was 3.2 (2.0-25.0) d. Pathological results showed that microinvasive adenocarcinoma was the most common type (38.5%, 50/130), followed by invasive adenocarcinoma (36.9%, 48/130); there were 3 metastatic tumors (3/130, 2.3%).Conclusion The combination of 3D-CTBA and ICG reverse staining is proved to be a safe, necessary and feasible method. It solves the difficult work encountered in the procedure of segmentectomy, and it is worth popularizing and applying in clinic.
The human gut microbiota regulates many host pathophysiological processes including metabolic, inflammatory, immune and cellular responses. In recent years, the incidence and mortality of lung cancer have increased rapidly, which is one of the biggest challenges in the field of cancer treatment today, especially in non-small cell lung cancer. Animal models and clinical studies have found that the gut microbiota of non-small cell lung cancer patients is significantly changed compared with the healthy people. The gut microbiota and metabolites can not only play a pro-cancer or tumor suppressor role by regulating immune, inflammatory responses and so on, but also be related with radiotherapy and chemotherapy of non-small cell lung cancer and the resistance of immunotherapy. Therefore, gut microbiota and related metabolites can be both potential markers for early diagnosis and prognosis in patients with non-small cell lung cancer and novel therapeutic targets for targeted drugs. This study will review the latest research progress of effect of gut microbiota on non-small cell lung cancer, and provide a new diagnosis and treatment ideas for non-small cell lung cancer.
Lung cancer has a high morbidity and mortality, and invasion is one of the major factors that cause recurrence and death in lung cancer patients. Tumor-associated macrophages (TAMs) are cells that have the potential to secrete cytokines, growth hormones, inflammatory substrates, and protein hydrolases, which are associated with the growth, invasion and metastasis of tumors. In this article, we will explore the various chemicals that are manufactured to promote the invasion of lung cancer, as well as the numerous clinical therapeutic features that TAMs possess in the treatment of lung cancer. In addition, we look at the possibility that TAMs might be beneficial in the treatment of lung cancer. We have an innovative investigation of the huge variety of complex substances generated by TAMs, with the goal of determining whether or not the molecules under investigation have the potential to serve as new therapeutic targets. Throughout the whole of the presentation, a significant focus is placed on doing in-depth research to ascertain whether TAMs have the capability to reinforce as viable carriers for unique and creative medications. This not only provides novel concepts for the creation of new targeted therapies but also leads to the development of brand-new, cutting-edge methods for the manufacture of individualized medicines and drug carriers.
Objective?To investigate clinical characteristics， diagnosis， and treatment for patients with spontaneous esophageal rupture， and improve clinical diagnostic and treatment level.?Methods?We retrospectively analyzed the clinical data of 34 patients with spontaneous esophageal rupture who were treated in Subei People’s Hospital from January 1996 to June 2010. There were 28 male patients and 6 female patients with their age ranging from 32 to 80 years old (mean 57.6 years old). Main clinical manifestations included severe chest and abdominal pain after vomiting， fever， dyspnea and shock. The duration between disease onset and establishing diagnosis ranged from 4 hours to 7 days. Thirteen patients received conservative treatment including chest drainage， retrograde gastrointestinal decompression and enteral nutrition through jejunostomy. Twenty one patients received surgical treatment including layered anastomosis of the ruptured esophagus， retrograde gastrointestinal decompression and enteral nutrition through jejunostomy.?Results?All the patients were cured without in-hospital death. The mean hospital stay of the 13 patients who received conservative treatment was 46 days， while that of the 21 patients who received surgical treatment was 17 days. All the ruptured esophagus were one-stage healed. All the 34 patients were followed up from l to 8 years， including 11 patients in the conservative treatment group and 19 patients in the surgical treatment group， but 4 patients was lost during follow-up. All the patients had a normal diet without symptoms of esophageal stricture， reflux esophagitis or chronic thoracic empyema.?Conclusion Spontaneous esophageal rupture is a thoracic emergency with a high misdiagnosis rate and mortality．Early diagnosis， early surgical repair of ruptured esophagus and satisfactory chest drainage play a vital role in the treatment for patients with spontaneous rupture of esophagus.
