In obese patients, what trocar modification is recommended?

In obese patients, what trocar modification is recommended?

• A. Use shorter trocars up to 70 mm
• B. Use standard trocars regardless of weight
• C. Use blind insertion
• D. Use longer trocars up to 100 mm

Answer: (D)

In patients with obesity, the abdominal wall is thicker, so accessing the peritoneal cavity safely and effectively requires longer instruments. Using longer trocars up to about 100 mm allows the cannula to reach the peritoneal space without needing extreme angles or additional manipulations, providing better reach for instruments and more stable pneumoperitoneum. Shorter or standard-length trocars may not penetrate deeply enough, leading to poor access, awkward angles, and increased risk of injury or failed entry. Blind insertion is particularly risky in this setting, so choosing longer trocars designed for greater tissue depth is the best approach to maintain safe and efficient entry.
