RESUMEN
We reported a case of a 36-year-old woman who presented with cough, dyspnea, hypereosinophilia, multiple pulmonary nodules and mediastinal lymphadenopathy. The percentage of eosinophils in bronchoalveolar lavage fluid (BALF) was as high as 65%. Pathogenic tests and cytologic examination of BALF were negative. Transbronchial lung biopsy and endobronchial ultrasound-guided transbronchial needle aspiration revealed only eosinophil infiltration. As the patient responded poorly to high-dose corticosteroids, a surgical lung biopsy was performed. The pathological diagnosis was angioimmunoblastic T-cell lymphoma. The patient received chemotherapy and achieved a partial response. Her eosinophil count returned to the normal range, and the pulmonary nodules on chest CT partially resolved.

Objective: To understand the epidemiological characteristics of human respiratory syncytial virus (HRSV) among acute respiratory infection (ARI) cases in 16 provinces of China from 2009 to 2023. Methods: The data of this study were collected from the ARI surveillance data from 16 provinces in China from 2009 to 2023, with a total of 28 278 ARI cases included in the study. The clinical specimens from ARI cases were screened for HRSV nucleic acid from 2009 to 2023, and differences in virus detection rates among cases of different age groups, regions, and months were analyzed. Results: A total of 28 278 ARI cases were enrolled from January 2009 to September 2023. The age of the cases ranged from<1 month to 112 years, and the age M (Q1, Q3) was 3 years (1 year, 9 years). Among them, 3 062 cases were positive for HRSV nucleic acid, with a total detection rate of 10.83%. From 2009 to 2019, the detection rate of HRSV was 9.33%, and the virus was mainly prevalent in winter and spring. During the Corona Virus Disease 2019 (COVID-19) pandemic, the detection rate of HRSV fluctuated between 6.32% and 18.67%. There was no traditional winter epidemic peak of HRSV from the end of 2022 to the beginning of 2023, and an anti-seasonal epidemic of HRSV occurred from April to May 2023. About 87.95% (2 693/3 062) of positive cases were children under 5 years old, and the difference in the detection rate of HRSV among different age groups was statistically significant (P<0.001), showing a decreasing trend of HRSV detection rate with the increase of age (P<0.001). Among them, the HRSV detection rate (25.69%) was highest in children under 6 months. Compared with 2009-2019, the ranking of HRSV detection rates in different age groups changed from high to low between 2020 and 2023, with the age M (Q1, Q3) of HRSV positive cases increasing from 1 year (6 months, 3 years) to 2 years (11 months, 3 years). Conclusion: Through 15 years of continuous HRSV surveillance analysis, children under 5 years old, especially infants under 6 months old, are the main high-risk population for HRSV infection. During the COVID-19 pandemic, the prevalence and patterns of HRSV in China have changed.

Objective: To investigate the clinical characteristics of a group of patients with adult-onset immunodeficiency (AOID) induced by anti-interferon-γ autoantibodies (AIGA). Methods: Thirteen cases of AOID in a northern China medical center (Peking Union Medical College Hospital) from October 2020 to April 2022 were included. Data comprising clinical manifestations, laboratory results, infection sites and pathogens were collected. Results: Among the 13 patients, 5 were male. The median age of disease onset was 47 (14 to 71) years. The median time from symptom onset to diagnosis was 4 years (1 to 8 years). Four patients were from northern China, and 9 from southern China. Common symptoms included lymphadenopathy (13/13), fever (12/13), respiratory tract symptoms (12/13), and weight loss (11/13). Laboratory tests showed increased levels of white blood cell count (9/13), neutrophil count and proportion (9/13), erythrocyte sedimentation rate (ESR) (12/13), and C reactive protein (CRP) (11/13). The median plasma titers of AIGA upon diagnosis were 5681(3194, 13246). Sites of infection included lungs (12/13), lymph nodes (9/13), bones and joints (9/13), skin and soft tissue (7/13), blood flow and bone marrow (4/13), and glands (3/13). Most patients had nontuberculous mycobacteria (NTM) (12/13) infection. Seven patients had more than one pathogen. Conclusions: AOID also affects patients visiting northern China hospitals. AIGA screening is recommended among patients with disseminated NTM infections or recurrent infections.

A 28-year-old male with a history of leukopenia was admitted with complaints of fever, cough, and dyspnea for 3 months. Initial work-up identified reduced circulating levels of granulocytes, monocytes, lymphocytes, and NK cells. Computed tomography revealed bilateral reticulonodular opacities and mediastinal lymph node enlargement. Peripheral blood culture and mediastinal lymph node aspiration yielded Mycobacterium avium. Genetic testing revealed a heterozygous germline GATA2 mutation (c.1187G>A, R396Q). Despite standard anti-mycobacterial therapy, the patient's dyspnea worsened and subsequent imaging studies revealed diffuse ground-glass opacification. A transbronchial lung biopsy confirmed the development of pulmonary alveolar proteinosis. Bone marrow transplantation had not been performed due to the unavailability of suitable donors. The disease progressed after whole lung lavage, and the patient died at the age of 31 years from respiratory failure. The current case report emphasized the importance of raising awareness about the rare GATA2 deficiency, which is characterized by hematologic abnormalities, primary immunodeficiency, and pulmonary alveolar proteinosis.

Primary ciliary dyskinesia (PCD) is a rare autosomal recessive or X-linked biallelic mutations inherited disease, characterized by motile cilia dysfunction. Typical manifestations include bronchiectasis, secretory otitis media, sinusitis, situs inversus, and infertility. PCD often needs to be differentiated from cystic fibrosis (CF) because of similar clinical manifestations. In this paper, a juvenile female who presented with recurrent cough and expectoration with fever since early childhood, had a history of secretory otitis media and sinusitis, and had been considered for the diagnosis of CF. After the discovery of compound heterozygous mutations in PCD related pathogenic genes by gene sequencing, combined with the clinical manifestations and imaging characteristics, PCD was finally diagnosed.

OBJECTIVE: Percutaneous endoscopic lumbar discectomy (PELD) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) have been commonly demonstrated as two effective choices for the treatment of lumbar disc herniation (LDH). This meta-analysis aims to compare the effects of PELD and MIS-TLIF for the treatment of single-segment LDH. MATERIALS AND METHODS: Randomized controlled trials or prospective cohort studies published from the time when databases were built to January 2022 that compared the effects of PELD and MIS-TLIF for single-segment LDH were retrieved from a comprehensive search in six electronic databases (PubMed, Web of Science, Embase databases, Cochrane Library, Google Scholar, and CNKI). All analyses were performed with RevMan 5.4 software. RESULTS: A total of 9 studies with 1274 patients were included in this meta-analysis. The results showed that the PELD group was associated with lower visual analog scales (VAS) score for back pain at the final follow-up (MD: 1.23; 95% CI: [0.32, 2.14], p=0.008), higher Japanese Orthopaedic Association (JOA) score (MD: 2.29; 95% CI: [1.38, 3.19], p<0.00001), lower Oswestry Disability Index (ODI) score (MD: -2.46; 95% CI: [-4.50, -0.43], p=0.02), shorter operation time at 3 months (MD: -51.77; 95% CI: [-74.63, -28.91], p<0.00001) and lesser hospital stay (MD: -5.18; 95% CI: [-6.65, -3.71], p<0.00001), and less blood loss (MD: -187.13; 95% CI: [-281.45, -92.81], p=0.0001). However, it was associated with a higher rate of recurrent disc herniation (RR: 17.66; 95% CI: [4.25,73.44], p<0.0001). There were no significant differences between PELD and MIS-TLIF in VAS leg pain (MD: 0.12; 95% CI: [-0.24, 0.49], p=0.51), and complication rate (RR: 0.71; 95% CI: [0.45, 1.12], p=0.14). CONCLUSIONS: The existing evidence showed that PELD had significantly better outcomes than MIS-TLIF in JOA score at six months, operation time, blood loss, and hospital stay as a procedure for LDH, but it had a higher recurrence rate than MIS-TLIF. Meanwhile, we should have a good command of the pros and cons of the two surgical methods to formulate an appropriate surgical plan for the patients.

We report an unusual case presented as acute gastrointestinal perforation and large confluent pulmonary cavities. A 23-year-old male was admitted to the emergency department with complaints of abdominal pain for 1 month, which exacerbated for 1 day. He also reported a 3-month history of diarrhea and productive cough. Computed tomography (CT) scan showed multiple large confluent cavities in the lung, along with massive free gas in the abdomen suggesting gastrointestinal perforation. Exploratory laparotomy was performed and affected bowel segment was resected. His sputum examination was positive for both acid-fast staining and Mycobacterium tuberculosis complex gene (Xpert) testing. Pathology of small intestine revealed micro-abscess formation and was positive for acid-fast bacilli. A final diagnosis of pulmonary tuberculosis and intestinal tuberculosis was made.

We reported a case of vascular Ehlers-Danlos syndrome presenting with recurrent pulmonary hemorrhage. A 22-year-old man was admitted for intermittent hemoptysis and chest pain during the past 18 months. Computed tomography of chest showed bilateral nodules and cavities with halo sign. Inflammatory markers, including erythrocyte sedimentation rate, C reactive protein and interleukin 6, were within normal range. The microbiological and pathological examination of bronchoalveolar lavage fluid and CT-guided percutaneous lung biopsy failed to draw a diagnosis. The pulmonary lesions waxed and waned despite empirical antibacterial, antifungal, antimycobacterial, and anti-parasite treatment. Video-assisted thoracoscopic lung biopsy showed pulmonary hemorrhage, hematoma, ossification, and fibrous nodules, suggesting vascular Ehlers-Danlos syndrome. The molecular testing revealed a heterozygous missense variant in the COL3A1 gene which confirmed the diagnosis of vascular Ehlers-Danlos syndrome. The patient had no skin hyperextensibility or joint hypermobility. During 3-year follow-up, there were no evidence of other vascular or organ involvement except he had intermittent minor hemoptysis. Through this clinical pathological discussion, we aimed to remind pulmonologist to consider the possible diagnosis of vascular Ehlers-Danlos syndrome in young patients with recurrent hemoptysis and waxing and waning pulmonary nodules, cavities, or cysts on CT scan who has neither obvious systematic inflammation nor effective reaction on empirical antimicrobial therapy. Molecular testing should be carried out as soon as possible in a suspected patient to avoid unnecessary invasive examinations.

A 52-year old man was admitted to our hospital because of dyspnea on exertion for 2 months and subcutaneous nodules for 1 month. Chest enhanced CT showed bilateral hilar and mediastinal lymphadenopathy. Bronchial alveolar lavage fluid revealed a CD4+/CD8+ T cell subsets ratio of 4.3 and culture for acid-fast bacillus (AFB) was negative. The pathology of skin nodules and transbronchial needle aspiration biopsy guided by endoscopic ultrasound (EBUS-TBNA) revealed non-caseating necrotizing epithelioid granulomas with negative acid-fast bacilli staining and periodic acid-Schiff staining, which was compatible with sarcoidosis. The patient was diagnosed as sarcoidosis and glucocorticoid was administrated. The subcutaneous nodules were improved. However, the lymph nodes were enlarged instead of shrinking after 6-month therapy. The failure to respond to glucocorticoids raised the possibility of sarcoidosis complicated with tuberculosis infection. The patient received anti-tuberculosis therapy. Lymphadenopathy responded within 4 months, and there was complete regression after 18-month treatment. The patient was followed up for 5 years and repeated chest CT scan showed that the sizes of bilateral hilar and mediastinal lymph nodes were normal.

Sclerotinia sclerotiorum is one of the most damaging and economically important necrotrophic plant pathogens, infecting more than 400 plant species globally. Although the phenylpyrrole fungicide fludioxonil has high activity against S. sclerotiorum, reports indicate that there is also substantial potential for the development of fungicide resistance. However, the current study investigating five fludioxonil-resistant laboratory mutants found a significant fitness cost associated with fludioxonil resistance resulting in significantly (P < 0.05) reduced mycelial growth and sclerotia formation on potato dextrose agar as well as significantly (P < 0.05) lower pathogenicity on detached tomato leaves, with one mutant, LK-1R, completely losing the capacity to cause infection. In addition, all of the fludioxonil-resistant mutants had significantly (P < 0.05) increased sensitivity to osmotic stress (0.5 M of potassium chloride and 1.0 M of glucose), which is consistent with the proposed fludioxonil target sites within the high osmolarity glycerol stress response mitogen-activated protein kinase (HOG1-MAPK) signaling transduction pathway. Sequence analysis of six genes from this two-component pathway, including SsHk, SsYpd, SsSk1, SsSk2, SsPbs, and SsHog, revealed several mutations that may be associated with fludioxonil resistance. For example, six separate point mutations were found in SsHk that led to changes in the predicted amino acid sequence, including A136G, F249V, G353A, E560K, M610K, and K727R. Similarly, SsPbs had three mutations (D34G, S46L, and L337E), SsSk1 and SsYpd had two (S53G and A795V for SsSk1, and E67G and Y141H for SsYpd), and SsHog and SsSk2 had one each (V220A and S763P, respectively). To our knowledge, these constitute the first reports of amino acid changes in proteins of the HOG1-MAPK pathway being associated with fludioxonil resistance in S. sclerotiorum. This study also showed a positive cross-resistance between fludioxonil and dimethachlone and procymidone, but none with tebuconazole or carbendazim, indicating that the inclusion of tebuconazole within an integrated pest management program could reduce the risk of fludioxonil resistance developing in field populations of S. sclerotiorum and ensure the sustainable production of soybeans in China into the future.

Novel coronavirus pneumonia was a novel coronavirus infection that has dominated pulmonary infection since December 2019. The main manifestations were fever, dry cough, shortness of breath, normal or leukopenia in peripheral blood and changes in chest CT and in severe cases, multiple organ failure might occur. The National Health Commission, PRC has revised the consensus on diagnosis and treatment seven times in a short period of time, indicating the growing understanding of the disease. Patients with novel coronavirus pneumonia usually had history of travelling or living in the epidemic area including Wuhan within 14 days before onset, or have been exposed to patients who had fever or respiratory symptoms from the epidemic area, or had clustering diseases. However, novel coronavirus pneumonia was becoming more and more blurred after vanishing epidemic. The diagnosis and differential diagnosis of novel coronavirus pneumonia were challenges not only because of large number of tourists increasing dramatically after the relieving of epidemic, but also patients with other diseases from different areas to search for medical care. In this article, the clinical and chest imaging features of the novel coronavirus pneumonia were reviewed and compared with other infections and non-infectious diffuse pulmonary diseases. We try to find the similarities and differences among them, and to identify clues to the diagnosis of novel coronavirus pneumonia, so as to ensure accurate diagnosis and treatment.

OBJECTIVE: To investigate the clinical and pathological features of immune-mediated necrotic myopathies (IMNM) with different myositis-specific antibodies (MSAs). METHODS: In the study, 104 IMNM patients who met any of the following three criteria were selected from idiopathic inflammatory myopathy patients who had MSAs results and underwent muscle biopsy from 2008 to 2018 in China-Japan Friendship Hospital: (1) Anti-signal recognition particle (SRP) antibody positive; (2) Anti-3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR) antibody positive; (3) MSAs negative and consistent with the pathological diagnostic criteria of IMNM defined by the European Neuromuscular Centre in 2004. The clinical, laboratory and muscle pathological information of the IMNM patients were retrospectively collected and compared in anti-SRP, anti-HMGCR and MSAs negative groups. RESULTS: Of 104 IMNM patients, 47 patients (45.2%) were positive for anti-SRP antibody, 23 (22.1%) were positive for anti-HMGCR antibody, and 34 (32.7%) were negative for MSAs. The common symptoms of IMNM patients were muscle weakness (92.3%), elevated serum creatine kinase level (92.3%), dysphagia (33.7%) and interstitial lung diseases (ILD) (49.5%). The anti-HMGCR-positive patients were more frequent to have "V" sign (30.4% vs. 4.3% and 5.9%, P<0.01) as compared with the anti-SRP-positive and MSAs-negative patients. The incidence of ILD in the anti-SRP-positive patients was higher than that in the anti-HMGCR-positive and MSAs negative patients (64.4% vs. 34.8% and 29.0%, P<0.01). The prevalence of the patients combined with other connective tissue diseases in MSAs-negative IMNM was higher than that in the other two groups (32.4% vs. 8.5% and 4.3%, P<0.01). 93.3% of the anti-SRP-positive patients were found with antinuclear antibody positivity, higher than those of the anti-HMGCR-positive and MSAs-negative patients (93.3% vs. 36.4% and 58.8%, P<0.001). The common pathological features of IMNM were muscle fibre necrosis (94.2%), regeneration (67.3%) and phagocytosis (65.4%), overexpression of major histocompatibility complexî1 on sarcolemma (78.8%), infiltration of CD4+ T cells (81.7%) and CD68+ macrophage (79.8%) and expression of membrane attack complex (MAC) (77.8%). The endomysial infiltration of CD4+ T cells and CD68+ macrophage and MAC expression on sarcolemma in the MSAs-negative group were more common than that in the anti-SRP and anti-HMGCR groups (88.2% vs. 57.4% and 60.9%, 91.2% vs. 59.1% and 38.1%, 76.5% vs. 45.5% and 42.9%, respectively, P<0.01). CONCLUSION: There is heterogeneity in anti-SRP-positive, anti-HMGCR-positive or MSAs-negative patients. The detection of MSAs and performing of muscle biopsy are useful for distinguishing different types of IMNM.

Objective: To investigate the efficacy, safety and compliance of dual therapy for the first-line eradication of Helicobacter pylori infection through a prospective, single-center and open-label cohort study. Methods: From March 2014 to September 2018, 200 naïve patients with Helicobacter pylori infection and dyspepsia received 14-day dual therapy (rabeprazole 10mg and amoxicillin 500 mg, four times daily orally). Safety and compliance were assessed 1-3 days after eradication. The therapeutic outcome was determined by (13)C-urea breath test 4-8 weeks after eradication. Some patients underwent strain culture, antibiotic sensitivity testing and CYP2C19 polymorphism assay. Results: The eradication rates of dual therapy: intention-to-treat analysis 87.5% (95% confidence interval 82.5%-91.5%), modified intention-to-treat analysis 90.2% (86.1%-94.3%) and per-protocol analysis 91.0% (86.3%-94.7). 21.2% of patients had adverse reactions, the majority were mild to moderate, and only 1.5% of patients discontinued medication because of intolerance to adverse reactions. Patients with good compliance accounted for 96.0%. Variate analyses showed that poor compliance and amoxicillin resistance were the independent risk factors for eradication failure. Conclusions: 14-day dual therapy with rabeprazole and amoxicillin (four times daily) achieved good efficacy, safety and compliance for the first-line eradication of Helicobacter pylori infection.

Objective: The aim is to analyze the fracture risk in rheumatic patients by fracture risk assessment tool (FRAX), which is recommended by World Health Organization (WHO), so that we can prevent the occurrence of osteoporotic fracture earlier. Methods: Totally 617 participants, 204 out-patients with rheumatism, 204 in-patients with rheumatism and 209 healthy controls, from March to October in 2018 of Fourth Medical Center of PLA General Hospital, Jishuitan Hospital and China-Japan Friendship Hospital, were enrolled in this study. The probability of hip fracture (PHF) and major osteoporotic fracture (PMOF) in 10 years with FRAX were compared, and the differences between taking sleroids or not and with or without bone mass density (BMD) of femoral neck were evaluated. Correlation analysis was conducted between PHF, PMOF and clinical information, including age, disease duration, gender, steroid usage, osteocalcin, P1NP and ß-crosslaps. Results: There was no significant difference in PMOF within 10 years (3.455±2.690 vs 2.973±2.149 vs 3.323±1.828) among the three groups (P>0.05), but the PHF (0.986±1.619 vs 0.515±0.873 vs 0.149±0.311) was different (P<0.05). PHF and PMOF increased gradually with age. PMOF of patients without glucocorticoid therapy in 10 years was lower than that of patients with glucocorticoid (3.554±2.584 vs 2.857±2.238, P<0.05). There is no difference between the results of FRAX calculated with BMD or not (3.012±2.231 vs 3.207±2.601, P>0.05). PHF and PMOF were positively correlated with age, course of disease, glucocorticoid use and osteocalcin level, while PHF was negatively correlated with TP1NP among in-patients. Conclusion: The prevalence of 10-year hip fracture calculated by FRAX in rheumatism patients is higher than that of healthy group. FRAX can be used to calculate fracture risk without BMD. Combination of FRAX and bone turnover markers may be more effective in prediction of osteoporotic fracture in rheumatic patients.

Objective: To understand the characteristics relating to the etiology and complications of hand, foot and mouth disease (HFMD) based on data from the pilot National Sentinel Surveillance (NSS) program so as to explore the feasibility, advantages and disadvantages of the NSS. Methods: Data were extracted from the NSS system, conducted in 11 provinces of China from November 2015 to October 2016. Characteristics regarding the etiology, complications of HFMD and factors related to the positive rates of HFMD specimens were analyzed under the logistic regression method by SPSS 20.0 software. Results: A total of 4 783 specimens were collected, including 3 390 from mild, 1 390 from severe and 3 from death cases. The overall positive rate was 81.43% (3 895/4 783). Other enteroviruses (non EV71/Cox A16 enteroviruses) appeared the major serotype (52.68%, 1 482/2 813) for mild infection of the disease while EV71 was for the severe cases (65.31%, 706/1 081). The serotype spectrum revealed by the pilot NSS was almost identical with the existing surveillance system. Other enteroviruses tended to infect younger children (χ(2)=130.17, P<0.001) than EV71 and Cox A16, in China. The multivariate logistic regression results showed that higher positive rate was associated with specimens which were collected from males, at children' hospitals, in peak seasons, timely and in stools. The positive rates presented downwarding trends with the extension of the onset-sampling interval (χ(2)=14.47, P<0.001 in stool specimen; χ(2)=31.99, P<0.001 in throat swab; χ(2)=24.26, P<0.001 in anal swab). Aseptic meningitis, non-brainstem encephalitis and brainstem encephalitis appeared the top three complications of both EV71-associated and other enteroviruses-associated severe HFMD cases. Conclusions: Factors as gender, season/place/timeliness of specimen collection, and types of hospital all appeared independently influenced the positive rates. NSS seemed feasible to be used as an alternative or supplement tool to the existing surveillance program in China.

Objective: To evaluate factors relevant to primary non-response in patients with Crohn's disease undergoing infliximab (IFX) treatment at week 14. Methods: Patients with Crohn's disease in the Third Hospital of Peking University who were subject to IFX treatment more than 3 times and followed-up for more than 14 weeks from October 2015 to October 2018 were reviewed. The response was defined by a decrease of ≥100 points from baseline in the Crohn's Disease Activity Index. The clinical data and laboratory examinations of the two groups were compared, and the treatment outcomes of non-responders were also followed up. Results: A total of 41 patients were enrolled, among which 27(65.9%) were male. The median age at treatment was 25 years, and 8 patients lost primary response (19.5%). There was no significant difference in the sex, age at diagnosis or treatment, Montreal disease type and laboratory examinations [C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), hemoglobin, albumin] in the response group and non-response group at baseline phase (P>0.05). Baseline CRP decreased from 17.7 (26.2) mg/L to 2.2 (3.6) mg/L in the response group, but increased from 11.7 (9.5) mg/L to 31.6 (28.4) mg/L in the non-response group at week 14 (P=0.024). The trend of ESR change in the response group [from 23.0 (28.5) mm/h to 7.0 (8.5) mm/h] and the non-response group [from 24.5 (22.5) mm/h to 35.0 (26.5) mm/h] was similar with that of CRP (P=0.036). Hemoglobin and albumin were significantly elevated in the response group, but not in the non-response group at week 14 (P=0.593, P=0.255). Among the non-response patients, 5 were converted to responsive after the treatment protocols had been adjusted. The combined immunosuppressant treatment all obtained clinical response. Conclusions: The elevated CRP and/or ESR may serve as indicators of primary non-response (at week 14) to IFX treatment among Crohn's disease patients, and the combination of immunosuppressive agents may be one of the effective treatments after excluding infection and other causes.

OBJECTIVE: To evaluate the efficacy and safety of submucosal tunneling endoscopic resection (STER) and endoscopic submucosal excavation (ESE) for upper gastroenterology submucosal tumors (SMT) originating from the muscularis propria (MP) layer. METHODS: Clinicopathological and endoscopic data of 42 cases with upper gastroenterology tumors originating from the MP layer who were treated with STER (n=28) or ESE (n=14) between April 2013 and December 2016 in Peking University Third Hospital were retrospectively analyzed. The treatment and complications of the two groups were compared. RESULTS: In the study, 42 cases were all resected by therapeutic endoscopy successfullyï¼There was no significant difference (STER vs. ESE) in gender, age, mean tumor size [1.5 (1.0-6.0) cm vs. 1.3 (0.5-2.0) cm, P=0.056]. STER was superior to ESE with reduced sutured time [3.5 (1.0-11.0) min vs. 8.0 (2.0-33.0) min, P=0.006], but more resection time [46.5 (11.0-163.0) min vs.19.5 (6.0-56.0) min, P=0.007]. There was statistical difference between the two groups in resection time or sutured time, but no significant difference (STER vs. ESE) in total operative time [52.0 (14.0-167.0) min vs. 31.5 (10.0-88.0) min, P=0.080]. En bloc resection rates (92.9% vs. 85.7%), hospital stay duration and complications (10.7 vs. 0.0) were similar in the STER and ESE groups. One case developed mediastinal emphysema and 2 pneumonia after operation in STER group, and all of them recovered uneventfully after conservative treatments; There were no complications in the ESE group. After operation, 28 cases of leiomyoma and 14 cases of stromal tumor were diagnosed by routine pathological and immunohistochemical staining. Among them, 6 cases of stromal tumors in group STER were all extremely low risk, 4 cases of stromal tumors in group ESE were extremely low risk, 4 cases of stromal tumors in group ESE were medium risk (the size of the lesion was about 1.0-2.0 cm, and mitotic figures counted (6-8)/50 high power field). The median follow-up time of all the patients was 46.5 (24-60) months, and the shortest follow-up time for medium risk stromal tumors was 32 months. No residual tumor, recurrence and implantation in the tunnel were observed. CONCLUSION: STER or ESE can be used as an effective and safe option for treatment of submucosal tumors originating from the muscularis propria of the upper digestive tract. Compared with STER, ESE had shorter resection time but longer wound closure time. There was no significant difference in total operation time.
