Abstract
BACKGROUND After esophagectomy for esophageal and esophagogastric cancer, more than half of patients have lost > 10% of their body weight at 12 months. In most cases, the gastric remnant is used for reconstruction after esophagectomy. One of the most serious nutritional complications of this technique is delayed gastric emptying caused by gastric remnant mobilization and denervation of the vagus nerve. The aim of the PYloroplasty versus No Intervention in GAstric REmnant REconstruction after Oesophagectomy (PYNI-GAREREO) trial is to analyze the clinical outcome of modified Horsley pyloroplasty (mH-P) as a method of preventing delayed gastric emptying. METHODS The PYNI-GAREREO trial is designed as an open randomized, single-center superiority trial. Patients will be randomly allocated to undergo gastric remnant reconstruction with mH-P (intervention group) or no intervention (control group) in parallel groups. All patients with esophageal cancer or esophagogastric cancer planning to undergo curative minimally invasive esophagectomy will be considered for inclusion. A total of 140 patients will be included in the study and randomized between the groups in a 1:1 ratio. The primary outcome is the body weight change at 6 months postoperatively, and the secondary outcomes are the nutritional status, postoperative complications, functional outcome, and quality of life until 1 year postoperatively. DISCUSSION We hypothesize that mH-P after minimally invasive esophagectomy more effectively maintains patients' nutritional status than no pyloroplasty.

Abstract
Delayed emptying of the gastric conduit following esophagectomy can be associated with an increased incidence of complications including aspiration pneumonia and anastomotic leak. The aim of this systematic review is to evaluate the current modalities of pyloric drainage following esophagectomy and their impact on anastomotic integrity and postoperative morbidity. Medline, Web of Science, Cochrane library, trial registries, and conference proceedings were searched. Five pyloric management strategies following esophagectomy were evaluated: no intervention, botulinum toxin (botox) injection, finger fracture, pyloroplasty, and pyloromyotomy. Outcomes evaluated were hospital mortality, anastomotic leak, pulmonary complications, delayed gastric emptying, and the late complication of bile reflux. Twenty-five publications comprising 3172 patients were analyzed. Pooled analysis of six comparative studies published after 2000 revealed pyloric drainage to be associated with a nonsignificant trend toward a reduced incidence of anastomotic leak, pulmonary complications, and delayed gastric emptying. Overall, the current level of evidence regarding the merits of individual pyloric drainage strategies remains very poor. There is significant heterogeneity in the definitions of clinical outcomes, in particular delayed gastric emptying, which has prevented meaningful assessment and formulation of consensus regarding the management of the pylorus during esophagectomy. Pyloric drainage procedures showed a non-significant trend toward fewer anastomotic leaks, pulmonary complications, and reduced gastric stasis when employed following esophagectomy. However, the ideal technique remains unproven suggesting that further collaborative investigations are needed to determine the intervention that will maximize the potential benefits, if any, of pyloric intervention.

Abstract
Abstract
Background
Reflux of gastric and duodenal content after oesophagectomy with gastric conduit reconstruction is a common problem and largely considered an inevitable consequence of surgery. Cervical burning and regurgitation, often more pronounced when supine, can be troublesome and even disabling, interfering substantially with quality of life. The aim of this study was to identify the factors contributing to reflux after oesophagectomy and evaluate measures to prevent or control it.
Methods
A Medline search using the terms ‘gastro-oesophageal reflux’, ‘oesophagectomy’ and ‘antireflux surgery’ was conducted. Additional references and search pathways were sourced from the bibliographies of articles located.
Results and conclusion
Reflux after oesophagectomy is a significant problem, with both clinical and pathological consequences. Simple measures to facilitate gastric emptying, such as creating a gastric tube, performing a pyloric drainage procedure and using gastric motility agents, may produce a reduction in symptoms but do not alone control reflux itself. A variety of surgical reconstructions have been used, many of which are either difficult to fashion or not suitable when a radical resection has been performed. A modified fundoplication at the anastomosis seems to be the simplest technique and may be relatively effective in controlling symptoms. The impact of strategies to reduce reflux on quality of life and on pathological sequelae of reflux in the oesophageal remnant remains to be evaluated.
