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.
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.
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.

Methods From December 2008 to June 2010, 14 patients with cervical intervertebral disc herniation underwent anterior cervical discectomy,spinal canal decompression,spinal canal decompression and reconstruction by n-HA/PA66 composite artificial vertebral body combined with plate instrumentation. The patients were followed up for 3 to 12 months with an average of 6.3 months. Neurological function was evaluated by improvement rate of JOA score and situations of the supporting body was observed by X-ray in 3,6,and 12 months after the surgery.The intervertebral height,the 1ocations, and the fusion rate of the supporting body were assessed in order to evaluate the stability of the cervical spine and alignment improvements. Results All the patients had undergone the operation successfully.The preoperative symptoms improved to varying degrees.JOA improvement rate were 87.0%, 94.0%, and 97.0% 3,6,and 12 months after the operation,respectively.Imaging studies showed that in all cases graft fusion were achieved,and cervical alignments,intervertebral height,cervical spine stability and the locations of the artificial vertebral body were well maintained.No displacement and subsidence of the artificial vertebral body occurred. Conclusion n-HA/PA66 artificial vertebral body can provide early cervical spine support and stability and cervical intervertebral height.It has a high rate of graft fusion and is convenient to observe by X-ray.Therefore,n-HA/PA66 can be taken as an ideal graft for anterior degenerative cervical spine operation,but further follow-up study is still needed to evaluate the long-term effects.
【Abstract】ObjectiveTo detect the spreading scope of rectal cancer to mesorectum by RT-PCR using carcinoembryonic antigen (CEA) mRNA as a marker and to investigate the excision scope of mesorectum in resection of rectal cancer. MethodsForty specimens from 40 rectal cancer patients who underwent curative operation was employed to detect the metastatic deposits scattered in the mesorectum by RT-PCR using CEA as a marker. ResultsNine of 40 (22.5%) specimens contained metastatic deposits scattered in the mesorectum. The metastasis was just within the range of 4cm mesorectum under the verge of tumor. The tumor spreading to mesorectum is correlated with Dukes stages，the infiltrated depth of bowel wall, tumor differentiation and tumor type(P＜0.05), and is not correlated with the size of tumor and the level of CEA(Pgt;0.05). ConclusionThe excision of mesorectum should be within the range of 5cm under the verge of tumor in surgical management of rectal cancer.
Objective To compare the cl inical effects of indirect decompression versus open decompression to vertebral canal in treatment of thoracolumbar burst fractures without neurologic deficit. Methods From April 2004 to June 2008, 52 cases of thoracolumbar burst fracture without neurologic deficit underwent posterior exposition, reduction and fixation with Atlas Fixator (AF) instrumentation. There were 34 males and 18 females with an average age of 43.1 years (range, 31-63 years). The affectd locations were T11 in 5 cases, T12 in 24 cases, L1 in 16 cases, and L2 in 7 cases. The time from injury to operation was 3-8 days (4.4 days on average). All cases were devided into indirect decompression group (group A) and open decompression group (group B). There were no statistically significant differences (P gt; 0.05) in sex, age, affect site, and disease course between two groups. The operative time, blood loss were recoded. Preoperatively, immediately postoperstively and at last follow-up, the height of the fracture vertebra and the Cobb angle were obtained from X-ray pictures and were statistically analysed. Radiographic parameters on computed tomography (CT) pictures were used to get the encroachment rate of vertebral canal. Results The operative time was (87.3 ± 7.9) minutes and (125.3 ± 13.6) minutes, and the blood loss was (273.7 ± 23.4) mL and (512.6 ± 37.7) mL in groups A and B, respectively; showing statistically significant differences (P lt; 0.05). The average follow-up time was 17.4 months (range, 11-31 months) in group A and 19.9 months (range, 12-33 months) in group B. All wounds achieved primary heal ing postoperatively without deaths and spinal cord injuries. Postoperative compl ications in group B included 3 cases of screws loosening, 1 case of screw breakage, and 3 cases of low back pain, and were given symptomatic management. There were no statistically significant differences (P gt; 0.05) in the height of the fracture vertebra, the Cobb angle andthe encroachment rate of vertebral canal preoperatively or postoperstively between two groups. There were statistically significant differences (P lt; 0.05) in the above three parameters between preoperation and postoperation in two groups, but there were no statistically significant differences (P gt; 0.05) in the spinal correction between two groups. The losing-rate of spinal correction of the height of the fracture vertebra and the Cobb angle of group A was lower than group B, showing statistically significant differences (P lt; 0.05). Conclusion The short-term results of two decompression styles in treatment of thoracolumbar burst fractures without neurologic deficit were satisfactory, but indirect decompression has more merits than open decompression: shorter operative time, less blood loss, lower losing-rate of spinal correction, and better stabil ization of vertebral column.
Day surgery is a new medical service model, which has developed rapidly in China because of its advantages of safety, efficiency and resource conservation. However, along with the rapid development in quantity, it also presents contradictions such as the mismatch with the previous surgical quality and safety management model, the urgent need for the unification of the new system of quality and safety evaluation indicators at the national level, and the imbalance in the construction of information technology of medical institutions in China, leading to the new problem of uneven quality control of day surgery. This article constructs a “five-in-one” new system for the quality and safety management of day surgery from the perspective of high-quality development, aiming to provide a theoretical basis for the formulation of relevant policies in China and to promote the safe, efficient, and orderly development of day surgeries.
ObjectiveTo investigate the clinical value of 3D CT combined with CT-guided Hookwire for localizing small pulmonary nodules in thoracoscopic pulmonary segmentectomy.MethodsFrom December 2017 to February 2019, 39 patients received thoracoscopic pulmonary segmentectomy in our hospital, including 14 males and 25 females with a mean age of 51.33±11.17 years. Before operation, we used Mimics Medical 20.0 to re-establish the anatomy of lung and locate the small pulmonary nodules with Hookwire guided by CT. Based on the position of Hookwire needle, 3D CT images and simulated surgical methods, thoracoscopic pulmonary segmentectomy was performed accurately.ResultsThe surgery was successfully completed in 39 patients without a transfer to open procedure. The mean operation time, mean intraoperative blood loss, mean postoperative hospital stay, mean thoracic tube drainage time were 148.97±28.56 min, 27.95±17.57 mL, 6.95±1.68 d, 4.21±1.95 d, respectively. Postoperative complications occurred in 5 patients (12.82%), including atrial fibrillation in 1, pulmonary infection in 1, chylothorax in 1, intrathoracic hemorrhage in 1 and pneumothorax in 1. All actual surgical margins were larger than 3.0 cm.ConclusionThe application of preoperative 3D CT combined with CT-guided Hookwire to localize small pulmonary nodules is helpful for accurate anatomical segmental resection of the lung, making the operation safe .
Objective To analyze the relationship between neuroticism and gastroesophageal reflux disease (GERD) using the Mendelian randomization (MR) method. Methods Exposure and outcome data were downloaded from the Integrative Epidemiology Unit (IEU) database in August 2023, including summary statistics from genome-wide association studies (GWAS) for neuroticism (n=374 323) and GERD (n=602 604). MR was conducted using the weighted median method, MR-Egger method, inverse variance weighted method, weighted mode method, and simple mode method. The causal relationship between the two was assessed using odds ratio (OR), and sensitivity analyses were performed to ensure the accuracy of the results. ResultsNeuroticism was associated with an increased risk of GERD [OR=1.229, 95%CI (1.186, 1.274), P<0.001]. Similarly, GERD was associated with an increased risk of neuroticism [OR=1.786, 95%CI (1.623, 1.965), P<0.001]. Conclusion There is a bidirectional causal relationship between neuroticism and gastroesophageal reflux disease.
ObjectiveTo systematically review the accuracy of the global leadership initiative on malnutrition (GLIM) in screening patients with cancer malnutrition. MethodsThe PubMed, Web of Science, Cochrane Library, Embase, CNKI, WanFang Data, SinoMed, and VIP databases were electronically searched to collect diagnostic tests related to the objectives from January 2019 to March 2024. Two researchers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using Stata 15.0 software. ResultsA total of 12 studies were included. The results of the meta-analysis showed that GLIM criteria for the diagnosis of malnutrition had a sensitivity of 0.69 (95%CI 0.63 to 0.76), specificity of 0.90 (95%CI 0.83 to 0.95), positive likelihood ratio of 7.18 (95%CI 4.17 to 12.35), negative likelihood ratio of 0.34 (95%CI 0.28 to 0.41), diagnostic odds ratio of 21.21 (95%CI 11.96 to 37.62), and area under the curve of 0.84 (95%CI 0.80 to 0.87). ConclusionCurrent evidence suggests that the GLIM criteria have diagnostic value as a tool for malnutrition in cancer patients, with moderate overall diagnostic efficacy.
