Objective Of The Study: The most common functional complication after Ivor-Lewis esophagectomy is the delayed emptying of the gastric conduit (DGCE) for which several diagnostic tools are available, e.g. chest X-ray, upper esophagogastroduodenoscopy (EGD) and water-soluble contrast radiogram. However, none of these diagnostic tools evaluate the pylorus itself. Our study demonstrates the successful measurement of pyloric distensibility in patients with DGCE after esophagectomy and in those without it.
Methods And Procedures: Between May 2021 and October 2021, we performed a retrospective single-centre study of all patients who had an oncological Ivor-Lewis esophagectomy and underwent our post-surgery follow-up programme with surveillance endoscopies and computed tomography scans. EndoFlip™ was used to perform measurements of the pylorus under endoscopic control, and distensibility was measured at 40 ml, 45 ml and 50 ml balloon filling.
Results: We included 70 patients, and EndoFlip™ measurement was feasible in all patients. Successful application of EndoFlip™ was achieved in all interventions (n = 70, 100%). 51 patients showed a normal postoperative course, whereas 19 patients suffered from DGCE. Distensibility proved to be smaller in patients with symptoms of DGCE compared to asymptomatic patients. For 40 ml, 45 ml and 50 ml, the mean distensibility was 6.4 vs 10.1, 5.7 vs 7.9 and 4.5 vs 6.3 mm/mmHg. The differences were significant for all three balloon fillings. No severe EndoFlip™ treatment-related adverse events occurred.
Conclusion: Measurement with EndoFlip™ is a safe and technically feasible endoscopic option for measuring the distensibility of the pylorus. Our study shows that the distensibility in asymptomatic patients after esophagectomy is significantly higher than that in patients suffering from DGCE. However, more studies need to be conducted to demonstrate the general use of EndoFlip™ measurement of the pylorus after esophagectomy.

Esophageal bronchial fistula after Ivor Lewis esophagectomy is a challenging complication. Surgical treatment is definitive, but it carries high morbidity and mortality, whereas esophageal stents have been shown to be temporary measures. We highlight the case of a patient who was treated with endoluminal wound vacuum therapy.

Background: Data about failure to rescue (FTR) after esophagectomy for cancer and its association with patient and procedure-related risk factors are limited. This study aimed to analyze such aspects, particularly focusing on the effect of pneumonia and anastomotic leak on FTR.
Methods: Patients who underwent an Ivor Lewis esophagectomy for cancer between 2008 and 2022 in 2 tertiary European centers were prospectively identified.

Background: Surgery for esophageal cancer has an associated high rate of postoperative complications such as anastomotic leakage (AL) and fistulas. Pre-operative sarcopenia as a loss of skeletal muscle mass and function is identified as a potential prognostic factor in determining the outcomes of oncological surgical resections for esophageal cancers. In this study, we evaluated the impact of body composition on postoperative complications in esophageal cancer surgery.
