Laparoscopic surgery involves insufflation of a gas (usually carbon dioxide) into the peritoneal cavity producing a pneumoperitoneum. This causes an increase in intra-abdominal pressure (IAP). Carbon dioxide is insufflated into the peritoneal cavity at a rate of 4–6 litre min−1 to a pressure of 10–20 mm Hg.
Why is pneumoperitoneum needed in laparoscopy?
Every laparoscopic surgeon should understand the consequences of pneumoperitoneum; so that its untoward effects can be averted. Pneumoperitoneum increases pressure on diaphragm, leading to its cephalic displacement and thereby decreasing venous return, which can be aggravated by the position of patient during surgery.
What are the two types of laparoscopy?
There are two types of laparoscope:
- a telescopic rod lens system, usually connected to a video camera (single chip or three chip)
- a digital laparoscope where a miniature digital video camera is placed at the end of the laparoscope, eliminating the rod lens system.
What is the process of laparoscopy?
During laparoscopy, the surgeon makes a small cut (incision) of around 1 to 1.5cm (0.4 to 0.6 inches), usually near your belly button. A tube is inserted through the incision, and carbon dioxide gas is pumped through the tube to inflate your tummy (abdomen).
What is a pneumoperitoneum?
The term pneumoperitoneum refers to the presence of air within the peritoneal cavity.
What is pneumoperitoneum in medical terms?
Pneumoperitoneum is the presence of air or gas in the abdominal (peritoneal) cavity. It is usually detected on x-ray, but small amounts of free peritoneal air may be missed and are often detected on computerized tomography (CT).
How does pneumoperitoneum affect cardiovascular function?
In general, pneumoperitoneum in excess of 15mmHg has deleterious effects on the cardiovascular system. The pneu- moperitoneum compresses the vena cava and thus decreases venous return to the heart; this results in blood pooling in the lower half of the body and a decrease in cardiac output.
What is the purpose of laparoscopy?
Laparoscopy can be used to help diagnose a wide range of conditions that develop inside the abdomen or pelvis. It can also be used to carry out surgical procedures, such as removing a damaged or diseased organ, or removing a tissue sample for further testing (biopsy).
What are the different types of laparoscopic surgery?

What is the purpose of a laparoscopy?
What are the indications for laparoscopy?
The clearest clinical indications for laparoscopic general surgery include cholecystectomy, weight loss procedures such as the Roux-en-Y gastric bypass, sleeve gastrectomy, and adjustable gastric band, Nissen fundoplication, Hellar myotomy, diagnostic laparoscopy, and staging laparoscopy.
How do you treat pneumoperitoneum?
This condition is a surgical emergency and may result in death if not addressed promptly. Needle decompression is the immediate treatment of choice, followed by surgery in most cases. The authors report a case of TP that was managed at their medical center.
What is the role of pneumoperitoneum in laparoscopic surgery?
Pneumoperitoneum is the essential component for laparoscopic procedures Even though a gasless approach has been described utilizing an intra-abdominal lift, this approach never been documented as better then pneumoperitoneum in healthy patient.
What is the meaning of pneumoperitoneum in peritoneal cavity?
Pneumoperitoneum means the presence of air within the peritoneal cavity and can be divided into 2 subgroups, surgical pneumoperitoneum (90%) and nonsurgical pneumoperitoneum (10%) 1).
How is the diagnosis of pneumoperitoneum (pneumonia) made?
If the pneumoperitoneum is large, the diagnosis can be made from the anteroposterior radiograph (Figure 22-19 ), but it is better shown in a horizontal-beam lateral, ( Figs. 22-20 and 22-21 ); a right lateral radiograph may be required to demonstrate smaller leaks ( Fig. 22-22 ).
How long does it take for a pneumoperitoneum to heal?
Likewise, not every bowel perforation results in a pneumoperitoneum; some perforations seal over, allowing little gas to escape. A pneumoperitoneum is common after abdominal surgery; it usually resolves 3-6 days after surgery, although it may persist for as long as 24 days after surgery.
