Summary Currently, the reports on esophageal endoscopic submucosal dissection (ESD) assisted by traction with a snare are rare. Because a snare is a commonly used endoscopic accessory and is easily available, its application in mucosal traction is worth exploring. The present study aims to evaluate the safety and effectiveness of snare-endoclip traction-assisted ESD for esophageal intraepithelial neoplasia. Cases of esophageal intraepithelial neoplasia resected using ESD in the Digestive Endoscopy Center of Guangzhou Nanfang Hospital, China from June 2013 to March 2019 were retrospectively analyzed. The procedure of snare-endoclip traction-assisted ESD was compared with nontraction-assisted ESD by using a propensity score matching analysis. Operation time, en bloc and R0 resection, intra- and postoperative complications, and surgery-related costs were mainly evaluated. Overall, 99 cases of esophageal intraepithelial neoplasia under tissue biopsy were included in the present study. Further, 22 exact matched pairs were obtained. There were no differences in en bloc and R0 resection rates, intra- and postoperative complications, and costs of disposable surgical accessories between the traction group and the nontraction group. However, median operation time showed a significant difference: traction group, 50.0 min (range, 20–100 min); nontraction group, 70.0 min (range, 35–133 min), P=0.012. In conclusion, snare-endoclip traction-assisted ESD for esophageal intraepithelial neoplasia was safe and shortened operation time in the study, thereby improving the efficiency of ESD. Despite the additional use of a snare and endoclips for traction, the total costs of endoscopic accessories seemed not to be increased.

Abstract Background To analyze whether neoadjuvant chemoradiotherapy (nCRT) could improve the survival for patients with adenocarcinoma of the esophagogastric junction compared with neoadjuvant chemotherapy (nCT). Both neoadjuvant chemotherapy alone and chemoradiotherapy before surgery have been shown to improve overall long-term survival for patients with adenocarcinoma in the esophagus or esophagogastric junction compared to surgery alone. It remains controversial whether nCRT is superior to nCT. Methods 170 Patients with locally advanced (cT3-4NxM0) Siewert II and III adenocarcinoma of the esophagogastric junction (AEG) were treated with neoadjuvant chemotherapy consisting of capecitabine plus oxaliplatin with or without concurrent radiotherapy in the Fourth Hospital of Hebei Medical University. Intensity-modulated radiation therapy (IMRT) was used and delivered in 5 daily fractions of 1.8 Gy per week for 5 weeks (total dose of PTV: 45 Gy). 120 Patients were included in the propensity score matching (PSM) analysis to compare the effects of nCRT with nCT on survival. Results With a median follow-up of 41.2 months for patients alive after propensity score matching analysis, the 1- and 3-year OS were 84.8%, 55.0% in nCRT group and 78.3%, 38.3% in nCT group (P = 0.040; HR = 1.65, 95% CI 1.02–2.69). The 1- and 3-year PFS were 84.9%, 49.2% in nCRT group and 68.3%, 29.0% in nCT group (P = 0.010; HR = 1.80, 95% CI 1.14–2.85). The pathological complete response (pCR) was 17.0% in nCRT group and 1.9% in nCT group (P = 0.030). No significant difference was observed in postoperative complications between the two groups. Conclusion The nCRT confers a better survival with improved R0 resection rate and pCR rate compared with nCT for the patients with locally advanced AEG.

Abstract Background and study aims Cold snare polypectomy (CSP) for small colorectal polyps has lower incidence of adverse events, especially delayed postpolypectomy bleeding (DPPB). However, few data are available on comparisons of the incidence of DPPB of CSP and hot polypectomy (HP). The aim of this study was to evaluate the incidence of DPPB after CSP and compare it with that of HP. A propensity score model was used as a secondary analysis. Patients and methods This was a retrospective cohort study conducted in a single municipal hospital. We identified 539 patients with colorectal polyps from 2 mm to 11 mm in size who underwent CSP (804 polyps in 330 patients) or HP (530 polyps in 209 patients) between July 2013 and June 2015. Results There were no cases of DPPB in the CSP group. Conversely, DPPB occurred in 4 patients (1.9 %) after HP, resulting in a significant difference between the CSP and HP groups (0.008 % vs 0 %, P = 0.02). Propensity score-matching analysis created 402 matched pairs, yielding a significantly higher DPPB rate in the HP group than CSP group (0.02 % vs 0 %, P = 0.04). However, significantly more patients in the CSP group had unclear horizontal margins that precluded assessment (83 vs 38 cases, P < 0.001). The retrieval failure rate was significantly higher in the CSP group than in the HP group (3 % vs 0.7 %, P = 0.01). Conclusions DPPB was less frequent with CSP than HP, as selected by the propensity score-matching model. Our findings indicate that CSP is recommended polypectomy in daily clinical setting. However, special care should be taken during polyp retrieval and horizontal margin assessment, and these issues could be taken into account in follow-up after CSP.

Superficial surgical site infections (S-SSIs), which prolonged hospital stay and increased costs, are a critical problem. The aim of the present study was to clarify the risk factors for S-SSIs after urgent gastroenterologic surgery and what surgeons can do to reduce their incidence and to shorten the hospital stay. A total of 275 patients who underwent urgent gastroenterologic surgery were enrolled in the present study. The correlations between the incidence of S-SSIs and clinicopathologic factors were retrospectively analyzed using propensity score matching. Of 275 cases, 43 (15.6%) patients had an S-SSI. On univariate analysis, the following factors were associated with a significantly higher incidence of S-SSI: American Society of Anesthesiologists score (P = 0.043); wound classification (P = 0.0005); peritonitis (P = 0.019); prolonged operation time (P = 0.0001); increased blood loss (P = 0.019); transfusion (P = 0.0047); and abdominal closure without triclosan-coated polydioxanone sutures (P = 0.042). However, a propensity score–matching analysis showed that abdominal closure using triclosan-coated polydioxanone sutures did not reduce the incidence of S-SSIs in patients who underwent urgent gastroenterologic surgery (P = 0.20), but it tended to be associated with a shorter hospital stay (P = 0.082). To reduce morbidity after urgent gastroenterologic surgery, surgeons should shorten the operation time and decrease the blood loss. In addition, abdominal closure using triclosan-coated polydioxanone sutures alone could not reduce the incidence of S-SSIs but might shorten the hospital stay after urgent gastroenterologic surgery by inhibiting bacterial activity and preventing prolongation of the infections.

Abstract Background: Despite the growing number of studies on the Coronavirus Disease-19 (COVID-19), little is known about the association of menopausal status with COVID-19 outcomes.Materials and methods: In this retrospective study, we included 336 COVID-19 in-patients between February 15, 2020 and April 30, 2020 at the Taikang Tongji Hospital (Wuhan), China. Electronic medical records, including patient demographics, laboratory results, and chest computed tomography (CT) images were reviewed. Results: In total, 300 patients with complete clinical outcomes were included for analysis. The mean age was 65.3 years and most patients were women (n=167, 55.7%). Over 50% of patients presented with comorbidities, with hypertension (63.5%) being the most common comorbidity. After propensity-score matching, results showed that men had significantly higher odds than premenopausal women for developing severe disease type (23.7% vs. 0%, OR 17.12, 95% CI 1.00–293.60; p=0.003) and bilateral lung infiltration (86.1% vs. 64.7%, OR 3.39, 95% CI 1.08–10.64; p= 0.04), but not for mortality (2.0% vs. 0%, OR 0.88, 95% CI 0.04–19.12, p=1.00). However, non-significant difference was observed among men and post-menopause women in the percentage of severe disease type (32.7% vs. 41.7%, OR 0.68, 95% CI 0.37–1.24, p=0.21) and bilateral lung infiltration (86.1% vs. 91.7%, OR 0.56, 95% CI 0.22–1.47, p=0.24), mortality (2.0% vs. 6.0%, OR 0.32, 95% CI 0.06–1.69, p=0.25).Conclusions: Men had higher disease severity than premenopausal women, while the differences disappeared between postmenopausal women and men. These findings support aggressive treatment for the poor-prognosis of postmenopausal women in clinical practice.

Abstract Thrombocytopenia is common among sepsis patients. Platelet transfusion is frequently administered to increase platelet counts but its clinical impacts remain unclear in sepsis-induced thrombocytopenia. The goal of this study was to explore the association between platelet transfusion and mortality in patients with sepsis-induced thrombocytopenia based on the Medical Information Mart for Intensive Care (MIMIC) III database. In this study, we included 1733 patients with sepsis-induced thrombocytopenia, and these patients were divided into two groups: platelet transfusion group (PT group) and no platelet transfusion group (NPT group). Propensity-score matching was used to reduce the imbalance. We found that patients in the PT group had a higher in-hospital mortality as compared with the NPT group. Furthermore, in the subgroup of age (>60 years), gender (female), sequential organ failure assessment score (≤8), simplified acute physiology score (≤47), platelet count (>27/nL), congestive heart failure, platelet transfusion was associated with increased in-hospital mortality. However, there was no significant difference in the 90-day mortality and the length of ICU stays (LOS-ICU) between these two groups. All these results remain stable after adjustment for confounders and in the comparisons after propensity score matching. In conclusion, platelet transfusion was associated with increased in-hospital mortality in patients with sepsis-induced thrombocytopenia.

788 Background: A number of retrospective studies reported that 5-year survival rate was 30-60% in patients who underwent curative resection of pulmonary metastases (PM) from colorectal cancer (CRC), and PM-CRC resection was recommended in clinical practice. Efficacy of adjuvant chemotherapy after resection of PM remains unclear. Therefore, using a large-scale data obtained from patients who underwent R0 resection of PM in Japan, we investigated it with a propensity score-matching analysis. Methods: We retrospectively collected clinical data of 1237 patients who underwent metastasectomy of PM-CRC at 46 Japanese institutions from 2004 to 2008. Excluding non-curative resection, preoperative chemotherapies, extra-thoratic metastases, complications after surgery, and inadequate data, 530 patients’ data (surgery alone 269 and surgery with adjuvant chemotherapy 261) were used for the matching. Patient backgrounds affecting doctor’s recommendation of adjuvant chemotherapy and including commonly reported prognostic factors were adjusted, using a propensity score-matching method. Primary and secondary endpoints were overall survival (OS) and disease-free survival (DFS), respectively. Results: After the matching with propensity-score, 167 patients for each group were selected. Patient backgrounds were balanced between both groups. Adjuvant chemotherapies were fluorouracil alone (67%), oxaliplatine-containing regimen (24%), irinotecan-containing regimen (7%) and others (2%). There were no significant differences between both groups in OS (HR 0.97, 95%CI 0.64-1.46, p = 0.88) and DFS (HR 0.99, 95%CI 0.75-1.32, p = 0.96). Conclusions: A propensity score-matching analysis did not show a survival benefit of adjuvant chemotherapy after resection of PM in patients with CRC. A large prospective observational study with high quality or randomized clinical trial is needed.

Background Regional anesthesia (RA) may help to circumvent the well-documented risks associated with general anesthesia, increase patient comfort and satisfaction, and mitigate costs. This study aims to investigate the utility of RA in extremity reconstruction. Methods The American College of Surgeons National Surgical Quality Improvement Program database was queried for all cases of extremity reconstruction including muscle, myocutaneous, or fasciocutaneous flaps from 2005 to 2016. Two groups were created based on anesthesia technique, regional/epidural and general. Postoperative complications included reoperation, readmission, and wound complications. Propensity score matching was utilized to control for variation in sample size, significant comorbidities, and demographics in the analysis of complications. Results A total of 2,874 cases were identified with general anesthesia utilized in 2,820 cases and RA in the remaining 54. After propensity score matching, 53 cases were identified in each group. In both unmatched and matched cohorts, there was no statistically significant difference in the rates of reoperation, readmission, or wound complication rates. In the matched cohort, mean operative time in the RA cohort was significantly shorter, 157.64 (±112.36) minutes compared with 293.06 minutes (±201.35 minutes) in the general anesthesia group (p < 0.001). While no statistically significant difference was detected in mean length of stay (LOS) between the two groups, the RA group experienced a clinically significant shorter LOS of 5.77 days (±5.87 days) compared with 7.02 (±5.61) days in the general anesthesia group (p = 0.269). Conclusion RA may be a safe, reasonable alternative to general anesthesia in extremity reconstruction without increase in postoperative complications. Additionally, RA use is associated with a significant reduction in operative time, potentially leading to shorter and safer procedures without compromising outcomes.
