La splénectomie par laparoscopie : indications, principes, résultats

Laparoscopic splenectomy (LS) has become the standard approach to splenectomy for benign and malignant hematologic diseases despite a paucity of high-level evidence. The procedure requires expertise in laparoscopic surgical techniques and meticulous dissection of the spleen. Management should include a preoperative radiologic assessment to measure splenic volume and to detect the presence of accessory splenic tissue; the patient should undergo preoperative vaccination against meningococcal, pneumococcal, and Haemophilus influenzae type B infections. Prophylactic antibiotics are used in the perioperative period as well as prophylactic anticoagulation therapy which may be continued long-term in high-risk patients. LS is associated with a low morbidity and mortality; when compared to laparotomy, it reduces the length of hospital stay and improves the quality of life by decreasing postoperative ileus and pain. There are a variety of laparoscopic approaches; the hand-assisted technique and newer coagulating devices have facilitated the operative technique leading to increasing acceptance of laparoscopy as the preferred approach - even in patients with malignant hematologic disease and/or massive splenomegaly.
