Laparoskopide Güvenli Abdominal Giriş Teknikleri
Özet
Laparoskopik cerrahi, postoperatif ağrıyı azaltması, hızlı iyileşme sağlaması, yara enfeksiyonu ve fıtık riskini düşürmesiyle avantajlıdır; ancak abdominal giriş sırasında nadir de olsa ciddi bağırsak ve büyük damar yaralanmaları riski taşır. Güvenli bir giriş için karın duvarı anatomisinin bilinmesi kritiktir. En sık tercih edilen giriş bölgeleri arasında vasküler ve sinir yapılarından yoksun olan karın orta hattı ve umblikus yer alır. Peritoneal kaviteye erişimde açık (Hasson) ve kapalı (Veres) teknikleri temel yöntemlerdir. Hasson tekniği karın katlarının direkt gözlemlenmesini sağlayarak yaralanma riskini azaltırken, Veres tekniği iğne yardımıyla daha hızlı kapalı giriş imkanı sunar. Pnömoperitoneum oluşturulurken genellikle karbondioksit gazı kullanılır ve ideal karın içi basınç 12-15 mmHg olarak ayarlanır. Alternatif olarak gelişen tek port (single port) cerrahisi kozmetik açıdan üstünlük sağlasa da derinlik algısının kaybı ve kısıtlı hareket alanı gibi teknik zorluklar barındırır. Obezite, gebelik ve geçirilmiş cerrahi gibi özel durumlarda giriş yerleri ve teknikleri hastaya göre özelleştirilmelidir. Komplikasyonları en aza indirmek için cerrahın tüm tekniklere hakim olması ve hastaya en uygun yöntemi seçmesi gerekir.
Laparoscopic surgery is advantageous as it reduces postoperative pain, enables rapid recovery, and lowers the risks of wound infection and hernia; however, it carries rare but serious risks of bowel and major vascular injuries during abdominal entry. Knowing the anatomy of the abdominal wall is critical for a safe entry. The most commonly preferred entry sites include the abdominal midline and the umbilicus, which lack significant vascular and neural structures. Open (Hasson) and closed (Veres) techniques are the primary methods for accessing the peritoneal cavity. While the Hasson technique allows direct visualization of the abdominal layers, reducing the risk of injury, the Veres technique offers a faster closed entry using a needle. Carbon dioxide gas is typically used to create pneumoperitoneum, with the ideal intra-abdominal pressure set at 12-15 mmHg. Alternatively, emerging single-port surgery provides cosmetic superiority but involves technical challenges such as loss of depth perception and restricted movement space. In special circumstances like obesity, pregnancy, and previous surgery, entry sites and techniques must be customized to the patient. To minimize complications, the surgeon must master all techniques and select the most appropriate method for the patient.
