About the Department of Gastroenterology at Hospital Cologne-Merheim

The Department of Gastroenterology at the Hospital Cologne-Merheim offers all the possibilities of modern medicine in the field of its competence. The medical facility provides diagnostics and effective treatment for diseases of the stomach, small intestine, large intestine, esophagus, and pancreas. The department's team of gastroenterologists has exceptional professional skills in the treatment of patients with oncological diseases of the gastrointestinal tract. In such cases, abdominal surgeons, oncologists, radiation therapists, and other highly specialized physicians work hand in hand. The department also has vast experience in the treatment of benign digestive diseases, including inflammatory bowel disease, gastroesophageal reflux disease, infectious gastrointestinal diseases, achalasia cardia, Zenker's diverticulum, gastritis, ulcers, polyps, etc. During treatment, the department's physicians strive to use only drug therapy and diet therapy, but they may also resort to endoscopic procedures. The department houses the largest Endoscopy Center in North Rhine-Westphalia, where more than 12,000 procedures are performed every year. The center has state-of-the-art equipment, thanks to which the efficiency and safety of endoscopic procedures are at a high level. High-quality sedatives are used for the maximum comfort of patients during endoscopic treatment. The department is headed by Prof. Dr. med. Arno Dormann.

In cooperation with abdominal surgeons, the department's doctors treat patients with gastrointestinal cancers. Of particular interest is the treatment of stomach and esophageal cancer. The resection of a malignant tumor is often required to achieve successful treatment outcomes. In the early stages of stomach and esophageal cancer, the specialists at the Endoscopy Center perform endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD). These procedures provide patients with good results but differ from classical surgery in that they are minimally traumatic and virtually free from surgical risks. The treatment of early-stage stomach and esophageal cancer with endoscopic procedures is inadvisable, so abdominal surgeons are involved in the therapeutic process, and their task is to remove the malignancy or perform a resection of the affected organ. The endoscopic procedure or surgery is often complemented by chemotherapy and/or radiation therapy.

The department's doctors regularly deal with the treatment of patients with gastroesophageal reflux disease (GERD). The pathology is chronic and occurs due to esophageal sphincter dysfunction, leading to the reflux of stomach acid into the esophagus and irritating its walls. Patients with suspected GERD may require examinations such as narrow-band imaging endoscopy, intragastric pH monitoring, impedance pH monitoring, swallowing assessment with contrast enhancement, chest CT scanning, and gastric scintigraphy. Treatment tactics are developed individually for each patient. Conservative treatment options are considered first, including lifestyle modifications (smoking cessation, weight loss, and a healthy diet) in combination with drug therapy using proton pump inhibitors and other drugs. In some clinical cases, effective results can only be achieved through surgery. In such cases, abdominal surgeons perform fundoplication or implant the LINX Reflux Management System. The last surgical option is innovative but has already proven to be highly effective. GERD surgery is performed using laparoscopic techniques.

The medical facility also provides medical care to patients with gastritis, gastric ulcers, achalasia cardia, Zenker's diverticulum, ulcerative colitis, Crohn's disease, stomach polyps, bowel polyps, and other benign pathologies. Doctors most often prescribe an individually developed drug therapy regimen and a diet to treat the above-mentioned diseases. The second-line treatment is endoscopic intervention, and in the most complex cases, minimally invasive surgery may be performed.
