We welcome you to the practice ZWEICHIRURGEN at our two locations directly on the Rhine in the heart of Basel and in the old town of Liestal. ZWEICHIRURGEN was founded in October 2018 by the two surgeons Prof. Philipp Kirchhoff and PD Henry Hoffmann. Our concept is based on taking the time to hear your questions and problems and then creating a treatment strategy based on a comprehensive understanding of your individual needs. We will coordinate a seamless first consultation in our office and if necessary a hassle free short hospital stay in one of the top private clinics in Switzerland. In addition, we keep your general practitioner informed and updated on the outcome of your time under our care.
We offer our many years of surgical experience where we specialized on cutting edge treatments for all types of hernias and proctologic diseases. In addition we perform standard surgical procedures such as gallbladder and intestinal resections.
We aim to build a relationship of trust and a high quality surgical experience with you. We look forward to your visit.

ZweiChirurgen with article about groin painGroin pain is a very frequent problem and needs a meticulous and focused clinical examination. More than 15 causes are described in the literature such as pathologies from muscles, bones or genital organs. A groin hernia only rarely causes pain. Instead, the most frequent complication of groin hernia surgery is chronic groin pain affecting more than 1500 patients per year in Switzerland. In such cases, a deep knowledge of the causes and the therapy strategies is required to help these suffering patients.

A hernia is a defect in the abdominal wall from which the contents of the abdomen protrude outwards from under the skin. Patients generally see a swelling and have discomfort or pain. Hernias are the most common surgical indication, and around 20,000 hernia operations are performed throughout Switzerland every year. The inguinal hernia is the most common, followed by hernia of the abdominal wall (e.g. umbilical hernias, scar hernias) flowed by rare causes such as flank hernia and diaphragmatic hernias.At our centre for hernia surgery we offer you competent and tailor-made advice and diagnostics. Depending on the clinical picture and the individual requirements of our patients, we perform open (larger skin incision) and minimally invasive surgical techniques (keyhole surgery) in accordance with current scientific findings and guidelines. Our many years of surgical experience enable us to offer you a surgical technique tailored to your needs. For minimally invasive operations, in many cases we also use a latest-generation surgical robot (Intuitive da Vinci Xi) which uses a 3D image to allow us to use the instruments even more precisely and gently.

Proctology deals with the diagnosis and treatment of diseases of the rectum. Common diseases of the rectum include hemorrhoids and anal fissures. In our center for proctology we offer you competent and comprehensive consultation, diagnostics and the complete therapy spectrum for all diseases of the rectum.Consultations, examinations and minor procedures take place in our practice. For certain examinations (e.g. colon and gastroscopy) we work closely together with gastroenterologists and other specialists. Should an operation be necessary, we perform it at our exclusive clinic partner Merian-Iselin-Clinic in Basel.
At our practice locations in Basel, Zurich and Liestal, we hold our consultation hours by individual appointment between 8-12 am and 2-6 pm. In a trusting and private atmosphere, we will take time to discuss your problems, ask you about your symptoms in detail, examine you professionally and draw up a diagnosis and therapy plan together with you. In addition, you will receive an information brochure with easy-to-understand text and illustrations about your diseases and treatment options.We also carry out the controls after a possibly necessary operation in our consultation hours. You will receive individual and competent advice from our specialists, and one doctor will remain responsible for you until you have recovered. If you would like to see a particular doctor, please let us know without hesitation.
We perform minor surgeries at our practice locations under local anesthesia. This includes, for example, minor operations on the anus and the surface of the body. After a preliminary discussion of the necessary procedure, we will plan the surgery date together with you. Please arrive at the practice on time for your appointment and allow about 1h of time. You should not schedule any other appointments on the day of the surgery so that you can recover in peace. No special preparations are necessary. You are welcome to eat and drink something before the operation. It is not necessary to shave the surgical site. For anus surgery, please do not perform an enema beforehand. After the operation, we will calmly discuss the further procedure with you. You will receive all the necessary documents from us (control appointments, certificates, prescriptions and behavioral instructions). We will be happy to offer you drinks and a small snack afterwards, if desired. In case of emergencies after the operation (e.g. post-operative bleeding), we are available for you by telephone around the clock.
The majority of our operations involve a hospital stay. We perform our operations exclusively at the Merian-Iselin Clinic in Basel. In rare cases, we also perform our operations at the Dornach Hospital.The Merian-Iselin Clinic is located in the center of Basel, is easily accessible by public transport and has 120 beds and nine operating rooms. The Merian-Iselin Clinic meets our high-quality standards with a perfect infrastructure, patient-oriented and friendly staff, the latest technical equipment in the operating room (e.g. surgical robots) and excellent hotel facilities. The clinic staff and our team always strive to make your hospital stay as pleasant as possible.After registering for surgery in our consultation hours, you will receive written confirmation of your appointment from the Merian-Iselin Clinic within a few days, including your appointment in the anesthesia consultation hours. There, all questions concerning the anesthesia will be discussed with you. On the day before the operation, you will be informed by telephone about the exact time of your admission to the hospital. As a rule, you will arrive about 1-2 hours before the start of the operation. As a rule, you will be admitted to the hospital on the day of the operation. In some exceptional cases it is also possible to arrive the day before the operation (private patients, long journey, etc.). You should not have eaten or drunk anything for at least six hours before the operation. You are allowed to drink clear liquids (water, tea without milk) up to two hours before the operation. At the hospital you will be met at the reception and then escorted to the entry station where you will be prepared for the surgery.
At ZweiChirurgen, work in the operating room is always performed according to the so-called «Cockpit Principle». Based on the work processes and safety measures of pilots in an airplane cockpit, our operations are always performed in pairs and according to a standardized procedure. The individual surgical steps are compared and checked according to the 4-eyes principle.
AAccording to the guidelines of the Federal Office of Public Health, some operations are performed on an outpatient basis (i.e. without an overnight stay in the hospital), provided that there are no exceptional criteria. These include, for example, unilateral inguinal hernia or hemorrhoids. The preparations for the operation are identical to those for an inpatient stay.After the operation you will be transferred to the day hospital where you can recover from the anesthesia. We will visit you at the day hospital before you are discharged. Once you have recovered from the surgery, pain is under control and circulatory parameters (pulse, blood pressure, etc.) are okay, you can be discharged home. All the necessary documents are included in our patient folder, which we will give you after the surgery. After your discharge from the hospital, you will usually have 1-2 more consultations in our consultation hours. We recommend that you have a relative pick you up. You should also not be alone at home for the first 24 hours. We are available for you by telephone after the operation.In rare cases, you may have to stay in the hospital for a night, contrary to what was planned. Sometimes the operation was more complex than expected, or there is still pain, nausea, circulatory weakness, or indisposition. This overnight stay in the hospital is then primarily for your safety and the patient's comfort.
In our practice we treat patients of all insurance classes and health insurance companies.Here you can make an appointment directly with the two surgeons, call us or write an e-mail to our practice.If you are insured in the general practitioner model (HMO), you should have your general practitioner refer you to us.In urgent cases, we will try to give you an appointment on the same day.
