Minimally invasive surgery for gastric GISTs ≤5 cm is safe and feasible. The final choice regarding a minimally invasive approach should be based on the tumor size, tumor location, pattern of tumor growth, and experience of laparoscopic surgeons.

Background:The choice of anastomosis methods including Billroth I, Billroth II, and Roux-en-Y after a distal gastrectomy is still controversial. The conventional meta-analyses assessing 2 alternative treatments were not powered to compare differences in clinical outcomes. To guide treatment decisions in patients with gastric cancer (GC) after distal gastrectomy, we did a systematic review and network meta-analysis to identify the best reconstruction method.Methods:We systematically searched PubMed, EMBASE, the Cochrane Library for randomized controlled trials comparing the outcomes of Billroth I, Billroth II, or Roux-en-Y reconstruction after distal subtotal gastrectomy for patients with GC, then we performed a direct meta-analysis and Bayesian network meta-analysis to pooled odds ratios (OR) or weighted mean differences (WMD) with 95% credible intervals (CrI) with random effects model. The node-splitting method was used to assess the inconsistency. We estimated the potential ranking probability of treatments by calculating the surface under the cumulative ranking curve for each intervention.Results:Nine studies involving 1161 patient were included in the network meta-analysis. Statistical significance was reached for the comparisons of Roux-en-Y versus Billroth I reconstruction (WMD 37, 95% Crl: 22–51) and Billroth II versus Billroth I reconstruction (WMD 25, 95% Crl: 5.8–43) for operation time; and Roux-en-Y versus Billroth I reconstruction (WMD 26, 95% Crl: 2.1–68) for intraoperative blood loss; and Roux-en-Y versus Billroth I reconstruction (OR 3.4, 95% Crl: 1.1–13) for delayed gastric emptying. Roux-en-Y reconstruction was superior to Billroth I and Billroth II reconstruction in terms of frequency of bile reflux (OR 0.095, 95% Crl: 0.010–0.63; OR 0.064, 95% Crl: 0.0037–0.84, respectively) and the incidence of remnant gastritis (OR 0.33, 95% Crl: 0.16–0.58; OR 0.40, 95% Crl: 0.17–0.92, respectively).Conclusion:Roux-en-Y reconstruction is superior to Billroth I and Billroth II reconstruction in terms of preventing bile reflux and remnant gastritis, Billroth I and Billroth II anastomosis could be considered as the substitute in consideration of technical simplicity. As for postoperative morbidity and the advantage of physiological food passage, Billroth I method is the choice.

Background: Physician burnout has been a global problem that affects severely the mental status among doctors, especially in emergency medicine (EM). However, few studies have focused on emergency medicine physicians, and the published data are inconsistent. Thus, this meta-analysis is performed to systematically evaluate the prevalence of burnout among emergency medicine physicians. Methods: We systematically searched databases including PubMed, Embase, PsychINFO and the Cochrane Library from inception to September, 2019 for English-language articles. We selected all the original articles those used Maslach Burnout Inventory to assess the prevalence of burnout and its 3 dimensions emotional exhaustion (EE), depersonalization, and personal accomplishment (PA) in emergency medicine physicians. After literature screening, quality evaluation was performed for eligible studies by using the Joanna Briggs Institute (JBI) critical appraisal checklist for studies reporting prevalence data; then, Begg test and Egger test was used to assess publication bias. Pooled prevalence rates were assessed by conducting a meta-analysis using random effects models. Then sensitivity analysis followed to test the stability of the result and detected the source of heterogeneity. Results: A total of 1943 EM physicians provided burnout data. The pooled prevalence rates of high levels of emotional exhaustion, high levels of depersonalization and low levels of PA were 40% (95% CI: 26%–55%; I 2 = 97.4%), 41% (95% CI: 30%–52%; I 2 = 94.5%) and 35% (95% CI: 19%–52%; I 2 = 99.0%), respectively. The mean burnout scores were 23.95 (SD = 11.88) for emotional exhaustion, 11.63 (SD = 6.85) for depersonalization, and 34.69 (SD = 7.71) for PA. Conclusions: This meta-analysis demonstrate a high level of burnout prevalent in EM physicians that approximately 40% experience high levels of EE and depersonalization. Our findings also suggest that EM physicians are more susceptible to burnout compared with physicians in other departments and other medical staffs in EM. More attention should be payed to mental status of EM physicians and further investigation concerning how to reduce burnout would be beneficial for EM physicians.

S-1-based chemotherapy and XELOX are likely to be the most effective adjuvant treatments for patients with resected gastric cancer. 5-FU alone provided little survival benefits as compared with surgery alone. Further clinical trials may be required to investigate S-1-based and XELOX-based adjuvant treatment strategies.

Background: Several neoadjuvant treatments are available for patients with resectable gastroesophageal cancer. We did a Bayesian network meta-analysis (NMA) to compare available treatments, summarizing the direct and indirect evidence.Method: We searched relevant databases for randomized controlled trials of neoadjuvant treatments for resectable gastroesophageal cancer which compared two or more of the following treatments: surgery alone, perioperative docetaxel, oxaliplatin, leucovorin, and fluorouracil (FLOT), and neoadjuvant treatments listed in National Comprehensive Cancer Network guideline. Then we performed a NMA to summarize the direct and indirect evidence to estimate the relative efficacy for outcomes including overall survival (OS), progression-free survival and R0 resection rate. We calculated odds ratio (OR) and hazard ratio (HR) with 95% credible intervals (CrI) for dichotomous data and time-to-event data, respectively. We also calculated the surface under the cumulative ranking curve (SUCRA) value of each intervention to obtain a hierarchy of treatments.Result: Eight eligible trials (2434 patients) were included in our NMA. The treatment with the highest probability of benefit on OS as compared with surgery alone was perioperative FLOT [HR = 0.58 with 95% CrI: (0.43, 0.78), SUCRA = 93%], followed by preoperative radiotherapy, paclitaxel, and carboplatin (RT/PC) [HR = 0.68 with 95% CrI: (0.53, 0.87), SUCRA = 72%], perioperative cisplatin with fluorouracil (CF) [HR = 0.70 with 95% CrI: (0.51, 0.95), SUCRA = 68%], and perioperative epirubicin, cisplatin, and fluorouracil or capecitabine (ECF/ECX) [HR = 0.75 with 95% CrI: (0.60, 0.94), SUCRA = 56%].Conclusion: Compared with surgery alone, perioperative CF, perioperative ECF/ECX, perioperative FLOT, and preoperative RT/PC significantly improved survival. Perioperative FLOT is likely to be the most effective neoadjuvant treatment for the disease. Further clinical studies are needed and justified.

Summary Many post‐bariatric patients have impaired health‐related quality of life (HRQoL) due to excess skin following weight loss; however, it is inconclusive whether body contouring surgery (BCS) improves this impairment. We aimed to comprehensively summarize existing evidence of the effect of BCS on the HRQoL (primary outcome) and determine the prevalence of, the desire for, and barriers to BCS (secondary outcomes). Randomized controlled trials, cohort, cross‐sectional, case–control, and longitudinal studies were systematically searched in PubMed, Embase, the Cochrane Central, and Web of Science. After screening 1923 potential records, 24 studies (representing 6867 participants) were deemed eligible. Only 18.5% of respondents from cross‐sectional studies underwent BCS, with abdominal BCS as the most common procedure. Most participants desired BCS but listed “cost” and “lacking reimbursement” as the main barriers. Results suggest that most post‐bariatric patients who underwent BCS experienced improvements in their HRQoL, which could be seen in almost every dimension evaluated, including body image and physical and psychosocial functions. Therefore, both bariatric and plastic surgeons should regard BCS not only as an aesthetic supplement but also as a vital part of functional recovery in the surgery‐mediated weight loss journey and, thus, provide it to more post‐bariatric patients.

Rationale: Intestinal ganglioneuromatosis (IGNM) is a rare disease, defined by an abnormal proliferation of ganglion cells, nerve fibers and Schwann cells in the enteric nerve system. Patient concerns: A 54-year-old woman presented with a one-year history of recurrent episodes of hypogastric pain, with vomiting, nausea, melena, and weight loss of 10 kg in recent 5 months. Diagnoses: The patient was diagnosed as a diffuse IGNM by pathological examination. Interventions: A complete excision of the tumor was performed. Outcomes: On follow-up after 26 months, the patient was asymptomatic without complications. Lessons: This report showed a rare case of diffuse IGNM not associated with NF1 or MEN2b. Preoperative radiological examination suggested an intestinal GIST, yet the final diagnosis of diffuse IGNM was made according to the pathological examination of the resected specimen. Although the prevalence of ganglioneuromatosis is low, this condition should be considered in the differential diagnosis of intestinal mass in adults.
