What are the complications of laparoscopic appendectomy?

Hemorrhage can occur due to technical errors in the introduction of trocars or in the handling of the mesoappendix.
Rupture of the appendix can occur, causing the release of appendicular content and increasing the risk of intra-abdominal abscess formation.
Contamination by rupture of the extractor bag can occur, increasing the percentage of wound infection and intra-abdominal abscesses.
Lesions of vessels and viscera can occur due to the injury caused by trocars or the Veress needle.
Ileus can occur as intolerance to oral fluids in the early postoperative period.
Intestinal obstruction can occur due to the formation of adhesions.
Abscess of the appendicular stump is an infrequent complication that appears in approximately 0.5% of appendectomies.
Intussusception of the appendicular stump is a rare complication, with less than 20 reported cases.
Hematoma-seroma can occur in 1% of patients and is usually secondary to injuries to blood vessels at the sites of incision for trocar placement.
Pulmonary complications have decreased due to the advantages of early ambulation and less pain associated with laparoscopic surgery.
Conversion to open surgery can occur due to various reasons, such as perforated appendix, cecal perforation, difficulty in mobilizing the appendix, bleeding, and technical problems with laparoscopic equipment.
Mortality rate is low, 0.08%, due to the decrease in general complications of the technique.
