— Areas of Expertise —
Individual assessment and a personalized treatment plan using the most current surgical techniques for every condition.
Colorectal cancer develops predominantly from adenomatous polyps. When detected early, it is highly curable with laparoscopic or robotic colectomy.
H. pylori infection, high-salt diet, and smoking are the principal risk factors. Laparoscopic gastrectomy with D2 lymphadenectomy achieves excellent outcomes in early-stage disease.
Hyperthermic intraperitoneal chemotherapy administered simultaneously with cytoreductive surgery for cancers that have spread to the peritoneum. Prof. Dr. Yanar is HIPEC-certified.
Hemorrhoidal disease affects approximately 75% of adults at some point. Grade I–II is managed conservatively; Grade III–IV requires laser hemorrhoidectomy or stapler hemorrhoidopexy.
A small tear in the anal canal mucosa causing severe pain and bright red bleeding during defecation. Chronic fissures require botulinum toxin injection or lateral internal sphincterotomy.
Protrusion of abdominal contents through a defect in the abdominal wall. Laparoscopic TEP/TAPP repair with mesh — same-day discharge in uncomplicated cases.
A chronic sacrococcygeal condition caused by hair penetration forming an infected sinus tract. Karydakis and Limberg flap techniques achieve a recurrence rate of only 3–7%.
Gallstone disease and acute cholecystitis are among the most common indications for general surgery. Laparoscopic cholecystectomy is the gold-standard treatment with same-day discharge.
Minimally invasive surgery using small incisions and the da Vinci robotic platform. Three-dimensional vision, tremor-free precision, and faster recovery than open surgery.
