BACKGROUNDPneumatic dilation and laparoscopic Heller's myotomy (LHM) are established treatments for idiopathic achalasia. Peroral endoscopic myotomy (POEM) is a less invasive therapy with promising early study results. METHODSIn a multicenter, randomized trial, we compared POEM with LHM plus Dor's fundoplica-tion in patients with symptomatic achalasia. The primary end point was clinical success, defined as an Eckardt symptom score of 3 or less (range, 0 to 12, with higher scores indi-cating more severe symptoms of achalasia) without the use of additional treatments, at the 2-year follow-up; a noninferiority margin of −12.5 percentage points was used in the pri-mary analysis. Secondary end points included adverse events, esophageal function, Gas-trointestinal Quality of Life Index score (range, 0 to 144, with higher scores indicating better function), and gastroesophageal reflux. RESULTSA total of 221 patients were randomly assigned to undergo either POEM (112 patients) or LHM plus Dor's fundoplication (109 patients). Clinical success at the 2-year follow-up was observed in 83.0% of patients in the POEM group and 81.7% of patients in the LHM group (difference, 1.4 percentage points; 95% confidence interval [CI], −8.7 to 11.4; P= 0.007 for noninferiority). Serious adverse events occurred in 2.7% of patients in the POEM group and 7.3% of patients in the LHM group. Improvement in esophageal func-tion from baseline to 24 months, as assessed by measurement of the integrated relax-ation pressure of the lower esophageal sphincter, did not differ significantly between the treatment groups (difference, −0.75 mm Hg; 95% CI, −2.26 to 0.76), nor did improve-ment in the score on the Gastrointestinal Quality of Life Index (difference, 0.14 points; 95% CI, −4.01 to 4.28). At 3 months, 57% of patients in the POEM group and 20% of patients in the LHM group had reflux esophagitis, as assessed by endoscopy; at 24 months, the corresponding percentages were 44% and 29%. CONCLUSIONSIn this randomized trial, POEM was noninferior to LHM plus Dor's fundoplication in controlling symptoms of achalasia at 2 years. Gastroesophageal reflux was more common among patients who underwent POEM than among those who underwent LHM. (Funded by the European Clinical Research Infrastructure Network and others; ClinicalTrials.gov number, NCT01601678.) AAchalasia is an esophageal motor disorder consisting of defective relaxation of the lower esophageal sphincter and disturbed esophageal peristalsis. The clinical symptoms associated with the condition include dysphagia, regurgitation, chest pain, and weight loss. 1 Current treatment options include endo-scopic botulinum toxin injection, endoscopic pneumatic dilation, and surgical laparoscopic Heller's myotomy (LHM). 2 These therapies allevi-ate symptoms, mainly by reducing lower esopha-geal sphincter pressure and lowering the resis-tance to flow at the esophagogastric junction. On the basis of findings from randomized trials, 3,4 recent consensus statements and guidelines sup-port both pneumatic dilation an...

Our non-randomized study showed that side-to-side LS technique is the preferred method of intrathoracic oesophagogastric anastomosis due to a decreased overall anastomotic leak rate and anastomotic stricture formation compared with HS technique.

Abstract:The presence of circulating tumor cells (CTCs) in patients with metastatic carcinoma is generally associated with poor clinical outcome. There have been many investigations showing a possible use of CTCs as minimally invasive predictive and prognostic biomarker in cancer medicine. In this report a size-based method (MetaCell ® ) for quick and easy enrichment and cultivation of CTCs is presented to enable possible CTCs use in esophageal cancer (EC) management. In total, 43 patients with diagnosed EC, 20 with adenocarcinoma (Adeno Ca) and 23 with squamous cell carcinoma (SCC), were enrolled into the adaptive prospective-like study. All the patients were candidates for surgery. The CTCs were detected in 27 patients (62.8%), with a higher rate in adenocarcinoma (75%) than SCC (52%). Finally, there were 26 patients with resectable tumors exhibiting CTCs-positivity in 69.2% and 17 patients with non-resectable tumors with 41.7% CTCs-positivity. Interestingly, in the patients undergoing neoadjuvant therapy, the CTCs were detected at time of surgery in 55.5% (10/18). The overall size-based filtration approach enabled to isolate viable CTCs and evaluate to their cytomorphological features by means of vital fluorescent staining. The CTCs were cultured in vitro for further downstream applications including immunohistochemical analysis. This is the first report of the successful culturing of esophageal cancer CTCs. The detection of CTCs presence could help in the future to guide timing of surgical treatment in

POEM resulted in greater than 90% treatment success at 12 months which tends to decrease to 84% after 2 years. More than one-third of the patients had mild reflux symptoms and/or mild esophagitis.

BackgroundEarly diagnosis of sepsis and its differentiation from the noninfective SIRS is very important in order that treatment can be initiated in a timely and appropriate way. In this study we investigated standard haematological and biochemical parameters and thromboelastography (TEG) in patients who had undergone surgical resection of the oesophagus to find out if changes in any of these parameters could help in early differentiation between SIRS and sepsis development.MethodsWe enrolled 43 patients (aged 41–74 years) of whom 38 were evaluable. Blood samples were obtained on the morning of surgery and then at 24-hour intervals for the next 6 days. Samples were analysed for procalcitonin (PCT), C-reactive protein (CRP), interleukin-6 (IL- 6), aspartate transaminase (AST), alanine transaminase (ALT) , lactate, white blood count (WBC), D-dimers, antithrombin (AT), international normalised ratio (INR), activated partial thromboplastin time (APTT) and parameters of TEG.ResultsSignificant differences between patients who developed sepsis during this period (9 patients) and SIRS were found in ALT on Day 1, in AST on Days 1–4, in PCT on Days 2–6; in CRP on Days 3–6; in IL-6 on Days 2–5; in leucocytes on Days 2, 3 and 6; and in D-dimers on Days 2 and 4. Significance values ranged from p < 0.0001 to p < 0.05.ConclusionsSequential measurements of ALT, AST, PCT and IL-6 during the early postoperative period can be used for early differentiation of sepsis and postoperative SIRS after oesophagectomy. Among the coagulation parameters measured, only D-dimer concentrations appeared to be helpful in this process. TEG does not seem to be a useful early predictor of sepsis development; however it can be used to differentiate sepsis and SIRS from Day 5 after surgery.
