Gastroesophageal reflux disease (GERD) is a global chronic disease. Short video platforms make it easy for patients with GERD to obtain medical information. However, the quality of information from these videos remains uncertain. This study aimed to systematically assess videos related to GERD on TikTok and Bilibili. We conducted a search and gathered 241 Chinese videos related to GERD and recorded the essential information. Two independent evaluators assessed each video based on the completeness of six components of the GERD guidelines, and assessed the quality and reliability of the information in the videos using recognition tools. Finally, videos from different sources were compared. The uploaders of most videos were medical professionals (86.7%, n = 209). The content was mainly about symptoms and treatment. The quality of the videos information varied depending on the sources. Among videos posted on Bilibili, those posted by medical professionals had a lower content score for definition (P < 0.001). Videos produced by non-gastroenterologists had the highest mean modified DISCERN. (The DISCERN scoring tool was initially created for assessing written publications, but nowadays, it is frequently leveraged for appraising various health-related videos. Details can be found in the text) quality of the videos information was acceptable; however, the content varied significantly depending on the type of source used. Videos with broad content should be carefully screened to meet more needs.

In submucosal invasive adenocarcinoma of the esophagogastric junction (pT1b-SM AEG), the extent of tumor submucosal (SM) invasion is measured using the vertical depth of SM invasion with the muscularis mucosa. This study aimed to investigate whether tumor thickness and depth of invasion without accounting for muscularis mucosa were superior to the vertical depth of SM invasion as metastasis predictors. We enrolled patients with pT1b-SM AEG who underwent endoscopic resection or surgical resection (SR) at our institution between January 2011 and September 2019 and were followed up for ≥2 years. The relationship between metastasis and clinicopathological factors was examined. Metastasis was defined as pathologically confirmed lymph node metastasis in the surgical specimen or recurrence during follow-up. This study included 57 patients (44 men; median age, 72 years). Endoscopic resection and SR were performed in 16 and 41 patients, respectively. Nine patients were diagnosed with metastasis: five who underwent SR showed pathologically confirmed lymph node metastasis in the surgical specimens, and four experienced recurrences during a median follow-up of 48 months. Univariate analyses showed that tumor thickness was significantly associated with metastasis (P = 0.021), and the vertical depth of SM invasion (P = 0.48) and depth of invasion (P = 0.38) were not. Furthermore, in multivariate analysis, tumor thickness ≥2800 μm (odds ratio, 38.70; P = 0.013) was a significant predictor for metastasis. Tumor thickness may be a more convenient and useful predictor of metastasis in patients with pT1b-SM AEG than the vertical depth of SM invasion.

Robot-assisted minimally invasive esophagectomy (RAMIE) for esophageal carcinoma has emerged as the contemporary alternative to conventional laparoscopic minimally invasive (LMIE), hybrid (HE) and open (OE) surgical approaches. No single study has compared all four approaches with a view to postoperative outcomes. A systematic search of electronic databases was undertaken. A network meta-analysis was performed as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-network meta-analysis guidelines. Statistical analysis was performed using R and Shiny. Seven randomised controlled trials (RCTs) with 1063 patients were included. Overall, 32.9% of patients underwent OE (350/1063), 11.0% underwent HE (117/1063), 34.0% of patients underwent LMIE (361/1063), and 22.1% of patients underwent RAMIE (235/1063). OE had the lowest anastomotic leak rate 7.7% (27/350), while LMIE had the lowest pulmonary 10.8% (39/361), cardiac 0.56% (1/177) complications, re-intervention rates 5.08% (12/236), 90-day mortality 1.05% (2/191), and shortest length of hospital stay (mean 11.25 days). RAMIE displayed the lowest 30-day mortality rate at 0.80% (2/250). There was a significant increase in pulmonary complications for those undergoing OE (OR 3.63 [95% confidence interval: 1.4-9.77]) when compared to RAMIE. LMIE is a safe and feasible option for esophagectomy when compared to OE and HE. The upcoming RCTs will provide further data to make a more robust interrogation of the surgical outcomes following RAMIE compared to conventional open surgery to determine equipoise or superiority of each approach as the era of minimally invasive esophagectomy continues to evolve (International Prospective Register of Systematic Reviews Registration: CRD42023438790).

This preclinical feasibility study investigates the potential of utilizing the hinotori™ robot system for esophagectomy. In three human cadaver models, the esophagus was successfully mobilized and resected using the hinotori™ system, with a mean thoracic procedure time of 57 minutes. The system allowed for precise dissection and radical lymphadenectomy without arm collision, attributed to its versatile design and docking-free trocars. Standard robot-specific patient positioning, including a 35° left lateral inclination, and trocar placement in a posterior axillary line configuration were employed. Notably, trocars suitable for both laparoscopy and the hinotori™ robot were utilized, providing flexibility in trocar selection. Unique features, such as the ergonomic console and pointer-based pivot point identification system, contributed to procedural success. While these findings highlight the promising potential of the hinotori™ system in advancing esophageal surgery, further clinical studies are warranted to validate its reproducibility and clinical utility. Additionally, enhancements to the pivot point identification system and evaluation of the arm base's features may further optimize surgical outcomes.

Advancements in neoadjuvant regimens for esophageal adenocarcinoma have enabled some patients to achieve complete pathologic response at time of esophagectomy. There are currently limited data detailing this trend or the implications of complete pathologic response on survival. The National Cancer Database was used to identify 16,169 patients with esophageal adenocarcinoma that received trimodal therapy including esophagectomy between 2006 and 2020. Of these, 11.4% had complete pathologic response at esophagectomy. Patient factors, staging characteristics, and survival trends were evaluated. In patients diagnosed between 2016 and 2020, the rate of complete pathologic response was 17.5%. Female sex (OR 1.295, 95% CI 1.134-1.481, p = 0.0001), Black race (OR 1.729, 95% CI 1.362-2.196, p = 0.0002), Hispanic ethnicity (OR 1.418, 95% CI 1.073-1.875, p = 0.0141), and later era of diagnosis (2016-2020 OR 2.898, 95% CI 2.508-3.349, p < 0.0001) were independent predictors of complete pathologic response. Clinical stage II disease was associated with an increased probability of complete pathologic response (OR 1.492, 95% CI 1.19-1.871) while clinical stage III disease had a decreased probability of complete pathologic response (OR 0.762, 95% CI 0.621-0.936, p < 0.0001). Complete pathologic response conveyed a strong survival benefit, with a median survival of 86.4 months (95% CI 73.9-102.1) versus 30.7 months (95% CI 29.8-31.7, p < 0.0001) in those without complete pathologic response. Four-year median survival was also higher in those with complete pathologic response (63.3%, 95% CI 60.8-66.0% vs. 39.2%, 95% CI 38.4-40.1%, p < 0.0001). In summary, complete pathologic response is associated with a profound survival advantage in patients with esophageal adenocarcinoma. Such knowledge carries implications for patient counseling, prognostication, and surveillance and demonstrates a need for improved identification of complete clinical response prior to esophagectomy.

Posterior thoracic para-aortic lymph node (TPAN) metastasis is a distant metastasis of esophageal cancer. Several case reports have shown that radical esophagectomy and lymphadenectomy for posterior TPAN improve the prognosis of patients with cStage IVB esophageal cancer and solitary posterior TPAN metastasis; however, the true value of this procedure is unclear. The primary objective of this study was to evaluate the short- and long-term outcomes of lymphadenectomy for posterior TPAN after induction chemotherapy in esophageal cancer. This study enrolled 15 patients who underwent radical esophagectomy for cStage IVB esophageal cancer with solitary posterior TPAN metastasis after induction chemotherapy between January 2013 and October 2022 at our hospital. The short- and long-term of radical esophagectomy and lymphadenectomy for posterior TPAN were retrospectively evaluated. All patients who underwent radical esophagectomy and lymphadenectomy for posterior TPAN achieved a pR0 in this study. The median operative time and intraoperative blood loss were 385 minutes and 164 ml, respectively. Four patients (26.7%) had postoperative complications of Clavien-Dindo grade II or more. The median postoperative hospital stay was 15 days. The 5-year overall survival and recurrence-free survival rates were 55.6% (95% confidence interval: 23.1-79.0) and 55.0% (95% confidence interval: 25.3-77.2), respectively. We showed that lymphadenectomy for posterior TPAN metastasis was associated with an improved prognosis of some patients with advanced esophageal cancer. This technique may serve as a viable treatment option for patients who respond well to induction chemotherapy.

The standard treatment regimen for esophageal cancer is chemoradiation followed by esophagectomy. However, the use of neoadjuvant chemoradiotherapy damages the surrounding tissue, which potentially increases the risk of postoperative complications, including anastomotic leakage. The impact of definitive chemoradiotherapy (dCRT, 50.4 Gy radiotherapy) compared to the standard neoadjuvant scheme (nCRT, 41.4 Gy radiotherapy) prior to surgery on the incidence of anastomotic leakage remains poorly understood. To study this, all patients who received dCRT between 2011 and 2021 followed by esophagectomy were included. For each patient, two patients who received nCRT were selected as matched controls. Outcomes included postoperative anastomotic leakage, pulmonary and other complications, anastomotic stenosis, pulmonary and other postoperative complications (Clavien Dindo Classification ≥1), and overall survival. One hundred and eight patients were included with a median follow-up of 28 months. The time between neoadjuvant treatment and surgery was longer in the dCRT group compared to the nCRT group (65 vs. 48 days, P < 0.001). Postoperatively, significantly more patients in the dCRT group suffered from anastomotic leakage (11% vs. 1%, P = 0.04) and anastomotic stenosis (42% vs. 17%, P < 0.01). No differences were found for other complications or overall survival between both groups. In conclusion, preoperative dCRT is associated with a higher risk of anastomotic leakage and stenosis. These complications, however, can be treated effectively. Therefore, esophagectomy after dCRT is considered to be an appropriate treatment strategy in a selected patient group.

Esophageal cancer presents a clinical challenge due to its high incidence and unfavorable prognosis. The prognostic role of the circumferential resection margin (CRM) remains highly controversial, potentially due to its temporal dynamics coupled with variability in follow-up durations across studies. We aimed to explore the time-dependent prognostic significance of CRM in T3 esophageal squamous cell carcinomas (ESCCs). We systematically reviewed literature from 1990 to 2023 to determine how follow-up duration influences the prognostic role of CRM in esophageal cancer. Concurrently, we performed a retrospective examination of 354 patients who underwent treatment at the National Cancer Center between 2015 and 2018. Integrating a time interaction term in the Cox regression analyses enabled us to not only identify independent risk factors affecting overall survival (OS) but also to specifically scrutinize the potential temporal variations in CRM's prognostic impact. Our literature review suggested that CRM's influence on prognosis diminishes with longer follow-up durations for both classifications, namely the Royal College of Pathologists (RCP) (β = -0.003, P < 0.001) and the College of American Pathologists (CAP) (β = -0.007, P < 0.001). Time-dependent multivariate Cox regression analysis emphasized the evolving nature of CRM's prognostic effect, and the inclusion of the time interaction term enhanced model accuracy. In conclusion, CRM is an independent prognostic factor for T3 thoracic ESCC patients. Its influence appears to decrease over extended follow-up periods, shedding light on the heterogeneity seen in previous studies. With the time interaction term, CRM becomes a more precise post-operative prognostic indicator for esophageal cancer.

Multidisciplinary team meetings (MDTs) are recommended for patients with esophageal cancer. Improved staging, timeliness to surgery and better adherence to guidelines have been attributed to MDTs, but there are few studies published on the MDTs' effect on survival. All patients with esophageal cancer in Sweden between 2006 and 2018 were grouped according to whether they had been discussed at an MDT as part of their clinical pathway. Factors affecting group allocation were explored with multivariable logistic regression, and the impact of MDT on survival was studied with Cox-regression and the Kaplan-Meier estimator. Of 6837 included patients, 1338 patients (20%) were not discussed at an MDT. Advanced age (80-90 years; odds ratio [OR] 0.25, 0.16-0.42 (95% confidence interval)) and clinical stage IVb (OR 0.65, 0.43-0.98) decreased the probability of being presented at an MDT, whereas high education level (OR 1.31, 1.02-1.67), being married (OR 1.20, 1.01-1.43), squamous histology (OR 1.50, 1.22-1.84) and later year of diagnosis (OR 1.33, 1.29-1.37 per year) increased the probability of an MDT. In multivariable adjusted analysis, MDT discussion was associated with improved survival (hazard ratios 0.72, 0.66-0.78) and median survival increased from 4.5 to 10.7 months. MDTs were associated with improved survival for esophageal cancer patients. Elderly patients with advanced disease and poor socioeconomic status were less likely to be presented at an MDT, but had clear survival-benefits if they were discussed in a multidisciplinary setting.

Gastroparesis (Gp) patients often have gastroesophageal reflux disease (GERD). Management of GERD in Gp patients is a challenge. Many studies have shown that gastric peroral endoscopic pyloromyotomy (G-POEM or POP) is moderately effective in reducing nausea and vomiting in patients with Gp. This study aims to determine whether G-POEM can improve GERD in Gp Patients. Patients who underwent G-POEM from July 2021 to October 2022 were enrolled in the study. GERD Health-Related Quality of Life (GERD HRQL) and Reflux Symptom Index (RSI) were used to assess patients' GERD before and after G-POEM. The use of proton pump inhibitors (PPIs) before and after G-POEM were also documented. The Gastroparesis Cardinal Symptom Index (GCSI) was used to assess the severity of Gp before and after G-POEM. A 'Welch two-sample t-test' was used to find differences in GERD HRQL (health-related quality of life) and RSI scores before and after the procedure. Pearson's chi-square test was used to find differences for use of PPI before and after G-POEM. Twenty-three consecutive refractory Gp patients with 30% male (average age 63.2) and 70% female patients (average age 53.9) were enrolled. Of these, 14 had diabetes, 3 had a history of surgery, and 6 had idiopathic Gp. The mean follow-up was 41 days (range 7-61 days). There was a significant decrease in the mean GERD HRQL score from 16.5 to 6.5 after G POEM with a P-value <0.0001 (95% level of significance) and a significant decrease in mean RSI score from 15.3 to 5.2 after G-POEM with P-value <0.0001 (95% level of significance). The proportion of use of PPI before GPOEM was 0.91, and the proportion of PPI use after GPOEM was 0.43 (P = 0.0008). The mean GCSI pre- and post-GPOEM were 3.53 and 1.59, respectively. Eighteen had clinical success in Gp as defined by decreased mean GCSI score greater than 1. In this short-term outcome study, 87% of patients' GERD HRQL scores and RSI scores decreased after G-POEM. These findings indicate that GPOEM not only effectively reduces Gp symptoms but also improves GERD symptoms leading to decreased or more effective use of PPI in these patients. To our knowledge, this is the first study to comprehensively show G-POEM significantly improves GERD. Further studies with a larger patient population and long-term outcomes are needed.
