Clinical and Endoscopic Services

The Department of Gastroenterology at the German Medical Institute offers a comprehensive range of clinical and endoscopic services for the diagnosis, management, and treatment of diseases affecting the digestive system. Our mission is to provide accurate, timely, and compassionate care using the latest medical knowledge, state-of-the-art technology, and a multidisciplinary approach.

Outpatient Clinical Services
Our daily outpatient clinics are staffed by experienced gastroenterologists who conduct thorough medical history evaluations, clinical examinations, and diagnostic consultations. Based on the findings, patients may receive a diagnosis, be referred for additional testing, prescribed medication, or scheduled for follow-up care or further specialist evaluation.

We provide close monitoring and management of a wide range of gastrointestinal and hepatopancreatobiliary disorders, including:

Gastroesophageal reflux disease (GERD)
Gastritis, gastric and duodenal ulcers
Inflammatory conditions or tumors of the digestive tract
Biliary, pancreatic, and liver diseases, including provision of liver biopsies when indicated
Chronic inflammatory bowel diseases such as Crohn’s disease and ulcerative colitis

When biologic therapy is indicated, patients may receive infusions in our specialized day care unit. In line with our holistic approach to care, the department collaborates with a clinical nutritionist and the broader paramedical team at GMI.

Endoscopic Services
Our department is equipped with the latest high-definition endoscopic systems and staffed by highly trained personnel, enabling us to perform a broad range of diagnostic and therapeutic endoscopic procedures with the highest standards of safety and comfort.

Except in rare cases, endoscopies are performed under sedation using propofol, ensuring a painless and well-tolerated experience. Patients typically recover within minutes and are discharged shortly thereafter. A detailed report with endoscopic images is provided prior to departure. For complex or invasive procedures, or when medically indicated, patients may be admitted for inpatient care.

Available Endoscopic Procedures:

Gastroscopy: Endoscopic examination of the esophagus, stomach, and duodenum, with or without biopsy. Routine urease testing for Helicobacter pylori is performed during the procedure.
Colonoscopy: Examination of the colon and terminal ileum, with or without biopsy.
Polypectomy / Endoscopic Mucosal Resection (EMR): Removal of benign or early malignant tumors. In many early-stage cancers, endoscopic resection alone may be curative.
Endoscopic Hemostasis: Treatment of gastrointestinal bleeding via hemostatic clips, submucosal adrenaline injection, thermal coagulation, or hemospray application.
Argon Plasma Coagulation: Treatment of angiodysplasias in the gastrointestinal tract.
Variceal Band Ligation: For the management of esophageal varices.
Balloon Dilatation: Treatment of strictures in the esophagus, stomach, duodenum, ileum, and colon.
Esophageal Stenting: Placement of bare metal stents under fluoroscopic guidance to manage esophageal strictures.
Percutaneous Endoscopic Gastrostomy (PEG): Placement or replacement of PEG tubes in patients unable to receive oral nutrition.
Endoscopic Ultrasound (EUS): For cancer staging, evaluation of submucosal tumors or pancreatic cysts, detection of bile duct stones, and assessment of extrahepatic biliary abnormalities.
Endoscopic Retrograde Cholangiopancreatography (ERCP): Including sphincterotomy, stone extraction, and stent placement for bile duct strictures.
Capsule Endoscopy: Evaluation of the small intestine for conditions such as obscure gastrointestinal bleeding, iron deficiency anemia, or suspected small bowel tumors.
