Esophageal achalasia is a type of motility disorder characterized by incomplete relaxation of lower esophageal sphincter (LES) and absence of esophageal peristalsis. Peroral endoscopic myotomy (POEM) is a new treatment option for achalasia that is less invasive, more effective, and safe as compared to surgery. High-frequency electrotome is commonly used in POEM, but takes longer time to make the tunnel in the esophagus and causes many complications. ⋯ Infection occurred in case 5 on the day of POEM was healed with antibiotics three days later. The 1940 nm thulium laser is feasible for POEM procedure. Further studies are needed to determine whether the 1940 nm thulium laser is better than high-frequency electrotome.

Multicenter Study
The long-term effects of early oral feeding following minimal invasive esophagectomy.
A nil-by-mouth regime with enteral nutrition via an artificial route is frequently applied following esophagectomy. However, early initiation of oral feeding could potentially improve recovery and has shown to be beneficial in many types of abdominal surgery. Although short-term nutritional safety of oral intake after an esophagectomy has been documented, long-term effects of this feeding regimen are unknown. ⋯ During admission, more re-interventions were performed in the delayed oral feeding group (17 vs. 46 patients P < 0.001). Esophagectomy reduces BMI in the first year after surgery regardless of the feeding regimen. Direct start of oral intake following esophagectomy has no impact on early nutritional re-interventions and long-term weight loss.

Dissection of lymph nodes (LN) immediately after esophagectomy is utilized by some surgeons to aid determination of LN stations involved in esophageal cancer. Some suggest that this increases LN yield and gives information regarding the pattern of lymphatic spread, others feel that this may compromise a circumferential resection margin (CRM) assessment. The aim of this study is to evaluate the effect of ex vivo dissection on the assessment of the CRM and the pattern of lymph node dissemination in patients with adenocarcinoma of the esophagus and gastroesophageal junction (GEJ) undergoing radical surgery after neoadjuvant chemotherapy and their prognostic impact. ⋯ Multivariate analyses identified ypT-category, ypN-category, male gender, and nonradical resection (proximal or distal) margin as significant prognostic factors. Surgical dissection of nodes after esophagectomy enables accurate LN assessment, but may compromise CRM assessment in up to 20% of cases. It also provides valuable information regarding the pattern of nodal spread.

To determine trends in the diagnostic distribution of esophageal motility disorders after implementation of the Chicago Classification Version 3.0 (CC V3.0) for interpretation of high-resolution manometry (HRM) studies compared to non-Chicago Classification criteria. Retrospective trends analysis of patients with an HRM study conducted at a single center from January 1, 2013 to September 30, 2015. The implementation of the CC V3.0 for manometry interpretation occurred in September 2014. ⋯ The percentage of indeterminate and major diagnosis decreased and EGJOO and minor diagnoses increased. The decrease in the number of indeterminate studies suggests that the CC V3.0 may clarify the criteria for the interpreting physician. The increase in studies with a diagnosis of EGJ outflow obstruction may reflect the heterogeneity of disorders with clinically relevant outflow obstruction.

Comparative Study
Comparison of short-term outcomes between 2- and 3-field lymph node dissection for esophageal cancer.
Although 3-field lymph node dissection (3-FLD) is often performed for thoracic esophageal squamous cell carcinoma (ESCC), the clinical effects of cervical lymph node dissection in addition to mediastinal and abdominal dissections on postoperative complications remain unclear. A total of 367 ESCC patients who underwent curative esophagectomy for thoracic esophageal cancer in our hospital from 2010 to 2015 were included in the study: 157 patients who underwent 2-field lymph node dissection (2-FLD) and 210 patients who underwent 3-FLD. Clinicopathological parameters and postoperative complications based on the Clavien-Dindo classification were compared between the two groups. ⋯ The duration of SIRS tended to be longer in the 3-FLD group than in the 2-FLD group, but the difference was not significant. The field of lymphadenectomy negatively impacted the short-term outcome in ESCC patients in terms of pneumonia and inflammatory response. However, because the results of the PSM analyses indicate that the short-term outcome was similar between the two groups, 3-FLD could be as feasible as 2-FLD in ESCC patients.
