Which is high risk for laparoscopic surgery
|D||Hb < 8gm%|
Some of the risks are described below:
a. The most significant risks are from trocar injuries to either blood vessels or small or large bowel. The risk of such injuries is increased in patients who are obese or have a history of prior abdominal surgery.
b. Some patients have sustained electrical burns unseen by surgeons who are working with electrodes that leak current into surrounding tissue. The resulting injuries can result in perforated organs and can also lead to peritonitis.
d. Many patients with existing pulmonary disorders may not tolerate pneumoperitoneum (gas in the abdominal cavity), resulting in a need for conversion to open surgery after the initial attempt at laparoscopic approach.
e. Gas tends to rise, and when a pocket of CO2 rises in the abdomen, it pushes against the diaphragm (the muscle that separates the abdominal from the thoracic cavities and facilitates breathing), and can exert pressure on the phrenic nerve.
f. Coagulation disorders and dense adhesions (scar tissue) from previous abdominal surgery may pose added risk for laparoscopic surgery and are considered relative contra-indications for this approach.
