Laparoscopic Port Selection and Placement Guidelines

Port Size and Type Selection

The American College of Obstetricians and Gynecologists recommends selecting the smallest trocar diameter that allows safe completion of the procedure to reduce trocar-site hernia rates, which increase significantly with ports ≥10 mm 1, 2
The incidence of trocar-site hernia ranges from 0.1-1.0%, though this is likely under-reported 3
Both 5-mm and 10-mm diameter laparoscopes are appropriate depending on the procedure, and consider using a 30-degree laparoscope to improve visualization and potentially reduce the need for additional ports 4
Prefer non-bladed trocars over bladed trocars when available, as bladed instruments demonstrate a statistically significant higher incidence of trocar-site hernia 1, 2, 5

Avoid midline trocar placement whenever possible, as midline location significantly increases trocar-site hernia rates 1, 2, 3
Place ports off-midline in pararectal or lateral positions to reduce hernia risk 1
Avoid midline incisions as extraction sites when performing laparoscopic interventions (strong recommendation, high-quality evidence) 7, 2, 5

Close the fascial defect for all trocar sites ≥10 mm to reduce trocar-site hernia risk 1, 2, 3, 5
Conventional multiport laparoscopic procedures are strongly recommended over single-incision laparoscopic surgery due to higher incisional hernia rates with single-incision laparoscopic surgery (moderate-quality evidence, strong recommendation) 1, 2, 3, 5

Maintain operating pressure at 12 mmHg during the procedure 8
The American College of Obstetricians and Gynecologists, the British Society for Gynaecological Endoscopy, and the Society of American Gastrointestinal and Endoscopic Surgeons recommend CO₂ insufflation of 10-15 mmHg, with adjustments based on patient physiology 4, 8
Consider reducing intra-abdominal pressure below 10-12 mmHg when possible to minimize physiological complications including decreased cardiac output, impaired renal blood flow, and elevated airway pressures 8

Use closed-circuit smoke evacuation or ultra-low particulate air filtration systems, and minimize use of energy devices and use low power settings when electrocautery is necessary 10, 6
The American College of Obstetricians and Gynecologists recommends using capnography for intraoperative CO₂ monitoring and avoiding maternal hypo- and hypercapnia 4
In pregnant patients with viable fetuses, perform fetal heart rate monitoring before and after surgery; intraoperative monitoring may be appropriate when emergent cesarean delivery would be considered 4
