High-risk submucosal esophageal adenocarcinoma's might be treated curatively by means of radical endoscopic resection, followed by thoracolaparoscopic lymphadenectomy without concomitant esophagectomy. A preclinical study has shown the feasibility and safety of this approach; however, no studies are performed in a clinical setting. In addition, sentinel node navigation surgery could be valuable in tailoring the extent of the lymphadenectomy. ⋯ There was a high concordance between imaging and probe-based detection of sentinel nodes. In conclusion, sentinel node navigation surgery followed by lymphadenectomy without concomitant esophagectomy seems feasible in patients with high-risk submucosal early esophageal adenocarcinoma. More evidence is however needed before applying this technique in clinical practice.

Observational Study
Vascular density of superficial esophageal squamous cell carcinoma determined by direct observation of resected specimen using narrow band imaging with magnifying endoscopy.
Observation of the microvasculature using narrow band imaging (NBI) with magnifying endoscopy is useful for diagnosing superficial squamous cell carcinoma. Increased vascular density is indicative of cancer, but not many studies have reported differences between cancerous and noncancerous areas based on an objective comparison. We observed specimens of endoscopic submucosal dissection (ESD) using NBI magnification, and determined the vascular density of cancerous and noncancerous areas. ⋯ For this ROC curve, sensitivity was 78.3% and specificity was 87.0% when the cutoff value of vascular density was 26 vessels/mm2. NBI magnification confirmed significant increases in vascular density in cancerous areas compared with noncancerous areas in esophageal squamous cell carcinoma. The rates of agreement between vascular density values determined by two independent operators were high.

Randomized Controlled Trial
Effect of alginate in patients with GERD hiatal hernia matters.
Alginate-based formulations are frequently used as add-on proton pump inhibitor (PPI) therapy to help control of heartburn and regurgitation. There are limited data regarding the mechanisms and effects of alginate-based formulations. We aimed to evaluate the effects of the sodium alginate intake and its likely temporal relations on intraesophageal reflux events by MII-pH in patients with and without hiatal hernia (HH). ⋯ There was no distinctive effect of alginate on the height of proximal migration of reflux events in patients with HH and without HH. Alginate decreases acid reflux events within a limited time period, especially at the first hour both in patients with and without HH. Alginate has no effect on the height of reflux events along the esophagus both in patients with and without HH.

Esophageal squamous cell carcinoma (ESCC) is associated with a poor prognosis and high postoperative recurrence rate. Although postoperative opioid use has been associated with cancer recurrence, its relevance in ESCC has not been determined. Therefore, this study investigated whether high-dose postoperative opioid use was associated with recurrence risk in patients with ESCC. ⋯ In contrast, postoperative opioid use was not associated with death (HR, 1.274; 95% CI, 0.922-1.761; P = 0.1422). In patients with ESCC, compared with low-dose opioid use, high-dose intraoperative and postoperative opioid use was significantly associated with an increased risk of recurrence. However, opioid dosage did not affect overall survival.

Review Meta Analysis
Postoperative pain management after esophagectomy: a systematic review and meta-analysis.
Effective pain management after esophagectomy is essential for patient comfort, early recovery, low surgical morbidity, and short hospitalization. This systematic review and meta-analysis aims to determine the best pain management modality focusing on the balance between benefits and risks. Medline, Embase, and the Cochrane library were systematically searched to identify all studies investigating different pain management modalities after esophagectomy in relation to primary outcomes (postoperative pain scores at 24 and 48 hours, technical failure, and opioid consumption), and secondary outcomes (pulmonary complications, nausea and vomiting, hypotension, urinary retention, and length of hospital stay). ⋯ Sample sizes were too small to draw inferences on opioid consumption, the risk of nausea and vomiting, hypotension, urinary retention, and length of hospital stay when comparing the different pain management modalities including systemic, epidural, intrathecal, intrapleural, and paravertebral analgesia. This systematic review and meta-analysis shows no differences in postoperative pain scores or pulmonary complications after esophagectomy between systemic and epidural analgesia, and between systemic and paravertebral analgesia. Further randomized controlled trails are warranted to determine the optimal pain management modality after esophagectomy.
