Compared with open surgery, patients experience significantly less pain, hospital stay is reduced to 1&ndash;3 days, and return to daily life is possible within 1&ndash;2 weeks.<\/div><\/div>\r\n    <div class=\"hy-faq-item\"><div class=\"hy-faq-q\">What is HIPEC and which conditions is it used for?<\/div><div class=\"hy-faq-a\">HIPEC (Hyperthermic Intraperitoneal Chemotherapy) is a heated chemotherapy technique administered simultaneously with surgery for cancers that have spread to the peritoneum. It is used primarily for peritoneal cancer, advanced colorectal cancer, and gastric cancer with peritoneal spread.<\/div><\/div>\r\n    <div class=\"hy-faq-item\"><div class=\"hy-faq-q\">How long does colon cancer surgery take?<\/div><div class=\"hy-faq-a\">Laparoscopic colon cancer resection takes an average of 2&ndash;4 hours depending on disease stage. Hospital stay following surgery is generally 3&ndash;5 days.<\/div><\/div>\r\n    <div class=\"hy-faq-item\"><div class=\"hy-faq-q\">How can international patients book an appointment in Istanbul?<\/div><div class=\"hy-faq-a\">International patients can book an appointment by calling +90 530 171 58 14 or contacting via WhatsApp in English, French or Russian. Medical interpretation support is also available.<\/div><\/div>\r\n    <div class=\"hy-faq-item\"><div class=\"hy-faq-q\">What should I eat after gallbladder surgery?<\/div><div class=\"hy-faq-a\">Following laparoscopic cholecystectomy, patients typically start on liquids the same day or the day after surgery. Fatty and fried foods should be avoided for the first 2&ndash;4 weeks. Most patients return to a normal diet within 7&ndash;10 days.<\/div><\/div>\r\n    <div class=\"hy-faq-item\"><div class=\"hy-faq-q\">Is surgery always necessary for hemorrhoids?<\/div><div class=\"hy-faq-a\">For mild to moderate hemorrhoids, a high-fiber diet, medication, and rubber band ligation may be sufficient. In advanced grades, laser treatment or surgical intervention may be required. The appropriate approach is determined following examination.<\/div><\/div>\r\n    <div class=\"hy-faq-item\"><div class=\"hy-faq-q\">How is inguinal hernia surgery performed?<\/div><div class=\"hy-faq-a\">Inguinal hernia repair is most commonly performed laparoscopically today. Through 3 small incisions, the hernia sac is reduced and the area reinforced with a synthetic mesh. The procedure typically takes 45&ndash;60 minutes and the patient can be discharged the same day.<\/div><\/div>\r\n    <div class=\"hy-faq-item\"><div class=\"hy-faq-q\">What is the difference between robotic and laparoscopic surgery?<\/div><div class=\"hy-faq-a\">In robotic surgery, the surgeon controls robotic arms from a console to perform the procedure. Compared with standard laparoscopy, it offers significantly greater precision and three-dimensional visualization. This provides a major advantage in complex operations within confined anatomical spaces.<\/div><\/div>\r\n  <\/div>\r\n<\/section>\r\n\r\n<!-- CTA -->\r\n<section class=\"hy-cta\">\r\n  <h2 class=\"hy-cta-h2\">Would You Like to Book an Appointment?<\/h2>\r\n  <p class=\"hy-cta-sub\">Easy appointment booking by phone, WhatsApp or contact form for domestic and international patients.
