RT Journal Article T1 Retroperitoneoscopy to extract dropped gallstones after laparoscopic cholecystectomy A1 Villar del Moral, Jesús Maria A1 Villegas-Herrera, Maria Trinidad A1 Medina-Benítez, Antonio A1 Ramia-Angel, Jose Manuel A1 Garrote-Lara, Daniel A1 Ferrón-Orihuela, José Antonio K1 Cuerpos Extraños K1 Cálculos Biliares K1 Laparoscopía K1 Masculino K1 Mediana Edad K1 Peritoneo K1 Colecistectomía Laparoscópica AB Complications resulting from gallstones left in the peritoneal cavity are most often reported after laparoscopic treatment of cholelitiasis. Gallstones are frequently dropped in the posterior subhepatic space, which can lead to the development of abscesses that usually require laparotomy for extraction of the stones. We present a novel technique for treating collections associated with dropped gallstones, using retroperitoneoscopy with two 10-mm ports after ultrasound localization of the abscess. We carried out this procedure in two patients and successfully extracted the gallstones without postoperative complications or recurrences. We consider this approach to be technically feasible, safe, and effective. It avoids the usual inefficacy of simple percutaneous drainage of these collections and the complications associated with the drainage of intra-abdominal abscesses by laparotomy.
