RESUMEN

Peroral endoscopic myotomy (POEM) is an intervention for the treatment of achalasia which has gained popularity over the last decade. It's efficacy and invasiveness are comparable to laparoscopic Heller myotomy (LHM). The purpose of this systematic review is to compare POEM to existing therapies. The systematic review was performed following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. MEDLINE, EMBASE, Web of Science and Cochrane Libraries were searched using keywords: esophageal achalasia, POEM, LHM, pneumatic dilation (PD), and related terms. The studied outcomes were Eckardt score, clinical success, hospital stay, cost-utility analysis, complications, and post-treatment gastro-esophageal reflux disease. Articles were reviewed by one researcher and uncertainty was resolved by a second researcher. The search strategy retrieved 1948 citations. After removing duplicates and applying the exclusion criteria, 91 studies were selected for full-text review of which a total of 31 studies were considered eligible for further analysis, including two studies which were found through manual searching. POEM has improved efficacy compared to PD with similar cost-effectiveness. POEM results showed comparable patient outcomes when compared with laparoscopic myotomy. Overall, POEM is a feasible first-line treatment for achalasia.

RESUMEN

Esophageal atresia (EA) is a rare congenital disease which is usually not of the detected prenatally. Due to the lack of prenatal diagnosis, some newborns with EA are born outside of specialized centers. Nevertheless, centralized care of EA has been proposed, even if a clear volume-outcome association in EA management remains unconfirmed. Furthermore, whether outcomes differ between outborn and inborn patients with EA has not been systematically investigated. Therefore, this single-center, retrospective study aimed to investigate EA management and outcomes with a special focus on inborn versus outborn patients. The following data were extracted from the medical records of infants with EA from 2009 to 2019: EA type, associated anomalies, complications, and long-term outcome. Patients were allocated into inborn and outborn groups. Altogether, 57 patients were included. Five patients were excluded (referral before surgery, loss of data, death before surgery [n = 1], and incorrect diagnosis [diverticulum, n = 1]). Among all patients, the overall survival rate was 96%, with no mortalities among outborn patients. The overall hospitalization period was shorter for outborn patients. The median follow-up durations were 3.8 years and 3.2 years for inborn and outborn patients, respectively. Overall, 15% of patients underwent delayed primary anastomosis (long-gap atresia [n = 4] and other reasons [n = 4]). Early complications included three anastomotic leakages and one post-operative fistula; 28% of patients developed strictures, which required dilatation, and 38% of patients showed relevant gastroesophageal reflux, which required fundoplication, without any differences between the groups. The two groups had comparable low mortality and expected high morbidity with no significant differences in outcome. The outborn group showed nonsignificant trends toward lower morbidity and shorter hospitalization periods, which might be explained by the overall better clinical status.

RESUMEN

Dysphagia is a common problem in patients with Parkinson's disease (PD); its etiology is multifactorial and its management is challenging. In this retrospective cohort analysis using prospectively collected data, we aimed to objectively characterize dysphagia and/or other esophageal symptoms in patients with PD, assess the prevalence of outflow obstruction as well as major or minor disorders of esophageal peristalsis leading to impaired esophageal clearance and highlight objective parameters that can help in the current management algorithm. Thirty-three consecutive patients with PD presenting with dysphagia, odynophagia, heartburn, regurgitation, chest pain, and weight loss underwent clinical and functional evaluation by high-resolution manometry (HRM). Esophagogastric junction (EGJ) outflow obstruction and major as well as minor disorders of peristalsis were then assessed using the Chicago classification (v3). Thirty-three PD patients with esophageal symptoms were enrolled in the study; 12 of them reported weight loss that was considered as potentially reflecting underlying esophageal dysfunction. The median age of the patients was 70 years (range: 53-89 years), 24 (75%) were men. The majority (62%) experienced dysphagia, likely contributing to weight loss in 41% of patients. Odynophagia was rare (6%) while GER symptoms, such as heartburn, regurgitation, and chest pain were noted in 37%, 31%, and 28% of patients, respectively. Using the hierarchy of the Chicago classification, 12 patients (39%) exhibited EGJ outflow obstruction, 16 (48%) diffuse esophageal spasm (DES), 18 (55%), ineffective esophageal peristalsis (IEM), 16 (48%) fragmented peristalsis, and only 2 patients (6%) had normal HRM tracings. There were no patients with HRM features of achalasia. Dysphagia is common in patients with PD and is associated with a high prevalence of underlying motility disturbances as identified by HRM. The exact impact of these motility abnormalities on symptom induction and their role in influencing clinical management are unclear and will require further study.

RESUMEN

The best-defined primary esophageal motor disorder is achalasia. However, symptoms such as dysphagia, regurgitation and chest pain can be caused by other esophageal motility disorders such as Diffuse Esophageal Spasm (DES), Nutcracker Esophagus (NE) and the Hypertensive Lower Esophageal Sphincter (HTN-LES). Most patients with DES and HTN-LES who complain of dysphagia improve after a myotomy. Patients with NE whose main complaint is chest pain, often do not have relief of the pain and can even develop dysphagia as a consequence of the myotomy. POEM is a relatively new procedure, and there are no studies with long-term follow-up and no prospective and randomized trials comparing it to surgical myotomy. Overall, the key to success is based on a complete evaluation and a careful patient selection. The best results, regardless of the technique, are in fact obtained in patients with outflow obstruction and impaired esophageal emptying, a picture similar to achalasia.

RESUMEN

Objective To explore the clinical significance of detection of plasma microRNA-21,-143 in identifying early esophageal cancer and esophageal non-tumor diseases.Methods The expression of plasma microRNA-21,-143 in 27 cases of patients with early esophageal cancer (esophagus cancer group),25 cases of patients with non-esophageal tumor (non-esophageal tumor group)and in the healthy controls were detected by RT-PCR,and detected the levels of plasma CEA and CA72-4 by the electrochemical luminescence technology,which of changes were analysed to observe the relationship between the changes and the esophageal cancer,the benign esophageal diseases for the two markers.Results The expression of plasma microRNA-21,-143 in the esophagus cancer group were 0.93±0.17,0.27±0.05,which of ones in the non-esophagus cancer group were 0.25±0.03,0.99±0.15,and with those in the control group were 0.23±0.03,1.02±0.15.Compared with those in the non-esophagus cancer group,the expression of plasma microRNA-21,-143 were obviously up or down-regulated with significant differences (t=10.87,11.55,P＜0.01).Compared with those in the control group,which of ones were obviously up or down-regulated with significant differences (t=9.20,9.07,P＜0.01),and with no statistical significances in comparison between the esophagus cancer group and the control group (t=1.39,1.19,P＞0.05).The positiverate of plasma microRNA-21,-143 in the esophageal cancer,non-esophagus cancer group and the control group were,81.4 ％ (22/27),4.0 ％(1/25) and 0 (0/24);85.1％ (23/27),4.0％ (1/25),and 0 (0/24),respectively.The positive rate of microRNA-21,-143 in the esophageal group respectively in comparison with those in the non-esophagus cancer group and the control group were significantly higher,the differences had statistical significances (x2 =31.59,34.39,P＜ 0.01;x2 =34.42,37.23,P＜ 0.01).The expression of two markers in the esophagus cancer group were no statistically significant differences compared with control group (x2 =0.980,0.980,P＞0.05).The sensitivity and specificity of microRNA-21,-143 in early diagnosis on the esophageal cancer were 81.4 ％,97.9 ％ and 85.1％,97.9 ％.The sensitivity of microRNA-21,-143 in the esophageal group were significantly higher compared with those of CEA and CA72-4,the differences were statistically significant (x2 =12.79,P＜0.01;x2 =5.33,P＜0.05;x2 =15.03,P＜0.01;x2 =6.95,P＜0.05).The specificity of microRNA-21,-143 in the esophageal cancer group were no statistically significant differences in comparison with those of CEA and CA72-4 (x2 =1.043,0.000,P＞0.05) and (x2=1.043,0.000,P＞0.05),respectively.The analysis results from the spearman correlation test showed that in the esophageal cancer group,the expression of plasma microRNA-21,-143 had a negative correlation (r =0.658,P＜0.01).Which of ones respectively associated with the levels of CEA and CA72-4 (r=0.607,0.623,P＜0.01 and r=0.579,0.610,P＜0.01).Conclution The detection of expression of plasma miRNA-21,miRNA-143 in the patients with the early esophageal cancer and non-esophageal tumor can provide a new train of thought for pathologic diagnosis of early esophageal cancer.

RESUMEN

Laparoscopic treatment of benign esophageal conditions is technically complex with several inherent limitations. Robotic-assisted surgery provides technical improvement and helps to overcome some of these limitations. We therefore report a single surgeon's experience in management of benign esophageal diseases by robotic-assisted surgery. Over a period of 8 consecutive years, a retrospective chart review was performed of 105 patients who underwent robotic-assisted surgery for benign esophageal diseases by a single surgeon. Demographic data and outcome measures were studied. The robotic-assisted procedures included 85 Nissen fundoplications with and without mesh repair, 12 Heller myotomies and eight para-esophageal hernia repairs. The mean total operating time was lowest for the Nissen group (94 min) and highest for the para-esophageal group (183 min). Operating time decreased from a mean of 105 min in the first 20 cases to 84 min in the last 20 cases for the Nissen group (P = 0.014). The mean length of stay was 1.3, 1.6, 1.5 and 4.8 days for the groups, respectively. Persistent symptoms of dysphagia/reflux/dysphonia requiring further investigation were seen in nine (8 %) of these patients. Two of these patients required repeat Nissen fundoplication in the mesh group. Our complication rate, total operating time and length of stay for robotic-assisted benign esophageal surgery are comparable to those reported in the literature. When performed by an experienced surgeon, robotic-assisted surgery is safe and effective in the management of benign esophageal diseases.
