- Positioning is in lithotomy position, ideally on a large vacuum cushion or non-slip mat
- It is recommended to position both arms (caution: cotton wrapping when positioning with a cloth sling), or to position one arm on the assistant's side
- Positioning of the legs in leg holders
- The legs should be adjustable via the operating table control
- If necessary, shoulder supports bilaterally to prevent the patient from slipping on the operating table
- For longer procedures, application of pneumatic compression cuffs for the legs for thrombosis prophylaxis
- If necessary, attachment of a cervical adapter
- Insertion of a urinary bladder catheter

Trocar positioning Palmer's point
The trocar placement in the area of the Palmer's point (or Palmer point) is a technique used to minimize the risk of complications by avoiding injury to abdominal organs, especially in patients with previous surgeries or suspected intra-abdominal adhesions. This point is located in the left upper abdomen.
Small puncture incision 2–3 cm below the left costal margin and 1–2 cm medial to the left midclavicular line. Insertion with a Veress needle or a (mini) optical trocar: A Veress needle is inserted through the abdominal wall into the left upper abdomen to create the pneumoperitoneum (CO₂ gas insufflation).
Thus, Palmer's point is an important alternative to the classic umbilical trocar placement and offers a safer access option for certain high-risk patients or when adhesions in the lower abdomen are suspected.

Miniature endoscope
Entering with the mini-optic and inspection of the abdomen. The mini-optic provides an initial, less invasive view of the intra-abdominal structures and allows for careful inspection without causing major damage.
Checking for injuries, bleeding, or adhesions, with particular attention to adhesions, as these could complicate the placement of additional trocars.
-
Positioning of the optical trocar
Based on the findings of the mini-optic inspection, it is decided where the main trocar for the optic (usually larger than the mini-optic trocar, e.g., 10 mm) can be safely placed. The goal is to find an adhesion-free area that provides sufficient distance from organs and adhesions to avoid injuries.
If adhesions are found in the area of the intended main trocar access, the access can be relocated. In this case, the optic trocar is also placed in the area of the Palmer's point after incision enlargement.
-
Diagnostic Laparoscopy
After placing the main trocar (usually 10 mm in diameter), the camera is introduced through the trocar. This main trocar serves as the primary access for visual control during the laparoscopic surgery.
First, a direct inspection of the trocar area is performed to ensure that the trocar is correctly placed and that no injuries, bleeding, or complications have been caused by the introduction.
Subsequently, the entire abdomen is inspected with an assessment of noticeable areas, as well as the determination of the position of additional working trocars in the adhesion-free area.
Under constant visual control by the camera, a skin incision is made and the working trocar (usuall
