About the Department of General and Abdominal Surgery, Colorectal Surgery, Endocrine Surgery and Hernia Surgery at Marien Hospital Duesseldorf

The Department of General and Abdominal Surgery, Colorectal Surgery, Endocrine Surgery and Hernia Surgery at the Marien Hospital Duesseldorf offers the full range of modern surgical interventions in the areas of its specialization. Every year, the medical facility performs more than 2,500 surgical interventions on an inpatient and outpatient basis. The department has vast clinical experience in the field of minimally invasive surgery, which allows the patient to avoid severe pain and prolonged hospitalization. The medical facility has the status of the Reference Center for Minimally Invasive Surgery and Hernia Surgery. Surgical treatment of cancer is one of the department's clinical priority focuses. The operating rooms of the medical facility are equipped with the very latest technology, while hygiene and safety standards are at the highest level as well. Prior to surgery, the patient undergoes a comprehensive examination. Doctors also assess the risks of the upcoming operation and its expected results. With appropriate clinical indications, preference is always given to minimally invasive surgery. The Head Physician of the department is Dr. med. Konstantinos Zarras.

As a rule, surgical intervention is the last-line therapy when conservative methods do not provide the desired result and cannot restore the patient's health as much as possible. Prior to any operation, the department's surgeon studies the patient's medical history and previously obtained diagnostic results, as well as prescribes the necessary additional tests to assess his general health and the risks of surgical treatment. Prior to the prescription of the operation, the surgeon holds an individual consultation with the patient, during which he talks about the course of the upcoming operation, surgical access, duration of the intervention, type of anesthesia, expected results and recovery period after the intervention. The department also successfully performs emergency surgical interventions (24 hours a day). It is worth noting that most surgical interventions are performed using sparing laparoscopic techniques. Depending on the particular clinical indications, operations can be performed under both local and general anesthesia. In addition, the department uses special programs for the accelerated recovery of patients' health after surgical treatment.

General and abdominal surgery is focused on various operations for gastrointestinal diseases. One of the primary areas of work of the department's team of surgeons is the treatment of benign and malignant tumors of the bowel and rectum, stomach, pancreas and other abdominal organs. Oncologists, interventional radiologists, radiation therapists and other doctors of related medical specialties are also engaged in the therapeutic process. Every week, the department holds interdisciplinary boards, during which each clinical case is considered in detail and an optimal treatment regimen is developed. Prior to surgery, the patient quite often undergoes neoadjuvant chemotherapy and/or radiation therapy to shrink the tumor before its subsequent resection. The specialists of the medical facility strictly follow the recommendations of professional societies and comply with modern clinical protocols, due to which high treatment success rates are achieved.

The department's surgical options are complemented by the treatment of endocrine disorders. Particular attention is paid to the treatment of thyroid and parathyroid pathologies. The ​​specialists are also competent in the provision of medical care to patients with pancreatitis, adrenal diseases and neuroendocrine tumors. When performing endocrine interventions, doctors use innovative neuromonitoring systems to control the condition of the vocal cords. Whenever possible, low traumatic surgical techniques are used, after which a long recovery is not required.

The team of colorectal surgeons of the medical facility performs surgical treatment of inflammatory bowel disease (Crohn's disease and ulcerative colitis), anal fistulas, abscesses and fissures, rectal prolapse, anal tumors, hemorrhoids and other pathologies. Complex clinical cases require classical open surgery, but most often, the specialists can achieve the desired result using minimally invasive techniques.

The department also specializes in hernia surgery: inguinal and umbilical hernias, epigastric hernias, diaphragmatic and incisional hernias. All surgical procedures for hernia repair are performed using minimally invasive techniques, so the patient's recovery takes place as soon as possible. It should be noted that the department has the status of the Reference Center for Hernia Surgery, which indicates the high competence of doctors in this field and the highest quality of treatment.
