Laparoscopic and robotic surgery methods offer less pain, rapid recovery, and small incision scars. Prof. Dr. Hakan Yanar prefers a minimally invasive approach in all suitable cases.
Laparoscopic surgery is a surgical method performed with cameras and special instruments by making small incisions of 0.5–1.2 cm in the abdominal region. It dramatically reduces all the disadvantages of traditional open surgery — long recovery, severe pain, large scars, and infection risk.
Robotic surgery (Da Vinci system) can be considered the technological evolution of laparoscopy. Thanks to a 3D HD imaging system and precise mechanical arms, the surgeon can operate with maneuverability exceeding open surgery in narrow anatomical areas (pelvis, esophagogastric junction).
📌 Prof. Dr. Hakan Yanar primarily evaluates a minimally invasive approach in all suitable cases. He determines the suitability of laparoscopic or robotic surgery through consultation.
| Procedure | Preferred Method | Feature |
|---|---|---|
| Gallbladder (Cholecystectomy) | Laparoscopic | Gold standard; same-day discharge |
| Colon Cancer Resection | Laparoscopic / Robotic | Oncological outcomes equivalent to open surgery |
| Rectum Cancer (TME) | Robotic (preferred) | Narrow pelvic space; sphincter preservation |
| Stomach Cancer (Gastrectomy) | Laparoscopic / Robotic | Standard D2 dissection |
| Groin/Umbilical Hernia | Laparoscopic (TEP/TAPP) | Bilateral single-session possibility |
| Appendicitis (Appendectomy) | Laparoscopic | Day-case; fast recovery |
The evidence-based advantages of the laparoscopic method compared to open surgery: postoperative pain is 60–70% less, hospital stay is 40–60% shorter, return to work time is 2–3 times faster, and the risk of wound infection is significantly lower.
It is also cosmetically superior: incisions of 0.5–1.2 cm become almost invisible over time; eliminating the anxiety of large scars in open surgery. Because it has less impact on the immune system, it is also advantageous in terms of post-operative healing physiology.
In anatomically limited areas such as the narrow pelvis and esophagogastric junction, the robotic system reaches points where the laparoscope cannot. In rectal cancer surgery, the robotic system is the preferred method to completely perform total mesorectal excision (TME).
Sphincter and pelvic nerve preservation (nerve-sparing surgery) are better achieved with the robotic approach; this directly impacts the quality of post-operative urinary and sexual function.
Prof. Dr. Hakan Yanar is an experienced surgeon with over 50 international publications in the field of minimally invasive surgery at Istanbul University Istanbul Faculty of Medicine and Liv Hospital Ulus. In all suitable cases, a laparoscopic or robotic approach is primarily evaluated. Language support is available in TR · EN · FR · RU.
