This document provides a history of laparoscopy and key developments in the field. It discusses early developments in the 1800s and 1900s using cystoscopes and insufflation. The first laparoscopy was performed in 1901 by George Kelling. Developments continued through the 1900s including the introduction of trocars and telescopes. Laparoscopic cholecystectomy was first performed in 1985 but was not widely adopted until the late 1980s. The document also discusses current standard laparoscopic procedures and emerging technologies like fluorescent cholangiography and natural orifice transluminal endoscopic surgery (NOTES).

107. Conclusion: Laparoscopy was associated with decreased risk of incisional infection but with an increased risk of OSI. The degree of this increased risk varies depending on the clinical profile of a surgical patient.

The dissection is proceeded using the retractors
To keep a working space, an external retractor is inserted through the skin incision in the axilla and is raised using a lifting device. A second skin incision (0.8cm in length) is made on the medial side of the anterior chest wall for the insertion of the fourth robot arm; apart 2cm superiorly, and 6~8cm medially from the nipple.
Four robotic arms are used for the operation. Three arms are inserted through the axillary incision, the dual channel endoscope is placed on the central arm, and the Harmonic curved shears along with the Maryland dissector is placed on both lateral side arms of the scope. The prograsp forceps is inserted through the anterior chest arm.
Despite these advantages, there are still many drawbacks to a conventional laparoscopy. The surgeon operates looking at a monitor that only shows a two dimensional image. The rigid instruments the surgeon works with are controlled from a distance; they have no wrists, which decreases precision, dexterity and control. As a result, the surgeon will also tire more quickly. Due to the small incision, the participation of the assistant is limited. This makes complex gynecologic operations very difficult, resulting in a higher likelihood that you will receive larger incision.
