Clinical and functional outcome following robotic Heller-myotomy with partial fundoplication in patients with achalasia.

Robotic-assisted myotomy with partial fundoplication for patients with achalasia has been established as a safe and effective procedure with similar short-term results and lower rates of intraoperative esophageal perforations. Our aim was to investigate a defined patient cohort undergoing robotic-assisted and laparoscopic surgery providing pre- and postoperative symptom score and high-resolution manometry to evaluate the clinical and functional outcome.All patients underwent clinical, endoscopic, radiological and manometric investigation to verify the diagnosis of achalasia.

Hyperspectral Imaging (HSI) in Acute Mesenteric Ischemia to Detect Intestinal Perfusion Deficits.

Background: Acute mesenteric ischemia is a life-threatening acute condition, which requires an interdisciplinary approach, including vascular recanalization and surgical treatment. Visual evaluation of intestinal perfusion might be misleading, and therefore, additional tools are necessary to reliably be able to resect the ischemic intestine. Hyperspectral imaging (HSI) has been shown to be feasible and safe for real-time assessment of tissue perfusion in visceral surgery but has never been used in cases of acute mesenteric ischemia.

Tissue classification of oncologic esophageal resectates based on hyperspectral data.

Purpose: Esophageal carcinoma is the eighth most common cancer worldwide. Esophageal resection with gastric pull-up is a potentially curative therapeutic option. After this procedure, the specimen is examined by the pathologist to confirm complete removal of the cancer.

Evaluation of hyperspectral imaging (HSI) for the measurement of ischemic conditioning effects of the gastric conduit during esophagectomy.

Background: Hyperspectral imaging (HSI) is a relatively new method used in image-guided and precision surgery, which has shown promising results for characterization of tissues and assessment of physiologic tissue parameters. Previous methods used for analysis of preconditioning concepts in patients and animal models have shown several limitations of application. The aim of this study was to evaluate HSI for the measurement of ischemic conditioning effects during esophagectomy.

Before and after Esophageal Surgery: Which Information Is Needed from the Functional Laboratory?

Background: Indications for benign esophageal surgery and postoperative follow-up need to be highly elaborated with differentiated and structured algorithms, based on objective functional workup in the esophageal laboratory. Functional outcome is of utmost interest and has to be driven by the need for comprehensive but purposeful diagnostic methods.

Methods: Preoperative diagnostic workup procedures by the functional laboratory include 24-h pH-monitoring, impedance testing, and high-resolution manometry (HRM) - in addition to upper gastrointestinal endoscopy and barium swallow/timed barium esophagogram.
