Treatment strategy of esophageal cancer mainly depends on accurate staging. At present, no single ideal staging modality is superior to another in preoperative tumor-node-metastasis (TNM) staging of patients with esophageal cancer. We aimed to investigate the efficacy of endoscopic ultrasonography (EUS) and positron emission tomography-computed tomography (PET-CT) for staging of esophageal cancer. ⋯ EUS is useful for initial staging of esophageal cancer. PET-CT is a more reliable modality for monitoring treatment response and restaging. Furthermore, the accuracy of PET-CT with regard to N staging is higher in patients who have undergone CRT than those who have not.

Comparative Study
Comparison of esophagectomy with and without thoracotomy in a low-resource tertiary care center in a developing country.
Esophageal cancer surgery is traditionally performed by a number of open surgical approaches. Open approaches require thoracotomy and laparotomy. Developments in instrumentation and optics have allowed the use of minimally invasive approaches to esophageal cancer, which had been traditionally managed by open operation. ⋯ MIE is oncologically safe compared with open surgery. It has almost similar postoperative course, morbidity pattern, and duration of hospital stay as open surgery. Increased duration of procedure compared with open surgery is a disadvantage of MIS, especially in the early part of learning curve.

Studies in the United States have revealed that gastroesophageal reflux disease (GERD) patients often suffer from nocturnal symptoms, sleep disturbance, and impaired quality of life. In a large subset of patients, these symptoms persist in spite of acid suppressive therapy. The aim of the present study was to assess the prevalence of heartburn and associated sleep complaints and the response to standard medical therapy with pantoprazole in primary and secondary care esophagitis patients in Belgium. ⋯ Smoking, alcohol use, higher grades of esophagitis, more severe typical reflux symptoms during daytime, and the presence of alarm symptoms are risk factors for GERD-related sleep disturbance. On standard therapy with pantoprazole, nighttime symptoms improved in more than 75%. These observations support a direct relationship between GERD and sleep disturbance.

Advanced esophageal endoscopic procedures such as stricture dilation, hemostasis tools, and stent placement as well as high-resolution manometry (HRM) interpretation are necessary skills for gastroenterology fellows to obtain during their training. Becoming proficient in these skills may be challenging in light of higher complication rates compared with diagnostic procedures and infrequent opportunities to practice these skills. Our aim was to determine if intensive training during a continuing medical education (CME) course boosts the knowledge and skills of gastroenterology fellows in esophageal diagnostic test interpretation and performance of therapeutic procedures. ⋯ The education program was rated highly. This study demonstrated that a CME course significantly enhanced the technical skills and knowledge of gastroenterology fellows in esophageal balloon dilation and HRM interpretation. CME courses such as this may be a valuable adjunct to standard fellowship training in gastroenterology.

Review Meta Analysis
Nonsteroidal anti-inflammatory drugs and esophageal inflammation - Barrett's esophagus - adenocarcinoma sequence: a meta-analysis.
The incidence of esophageal adenocarcinoma has markedly increased in the last few decades and Barrett's esophagus is regarded as the precursor lesion of this cancer. The aim of the study was to quantify the adenocarcinoma risk associated with nonsteroidal anti-inflammatory drug use and to determine at which stage chemoprevention with this drug is the most effective in esophageal inflammation - Barrett's esophagus - adenocarcinoma sequence. A literature search was performed to identify studies published between 1998 and 2009 for relevant risk estimates. ⋯ In addition, we discovered a reverse association between drugs use and adenocarcinoma risk in people without a history of upper gastrointestinal tract disorders (OR: 0.57, 95% CI: 0.43-0.77, P= 0.12). Our meta-analyses suggest a protective effect of nonsteroidal anti-inflammatory drugs on the risk of adenocarcinoma. Our results also suggest that the drugs might act after the formation of Barrett's epithelium in the esophageal inflammation - Barrett's esophagus - adenocarcinoma sequence.
