title: Single-port laparoscopic cryptorchidectomy in dogs and cats: 25 cases (2009-2014).
abstract: OBJECTIVE
  To describe the operative technique for single-port laparoscopic cryptorchidectomy (SPLC) in dogs and cats and evaluate clinical outcome for patients that underwent the procedure.
  
  
  METHODS
  Retrospective case series.
  
  
  METHODS
  25 client-owned dogs (n = 22) and cats (3).
  
  
  METHODS
  Dogs and cats that underwent SPLC with 3 commercially available single-port devices between 2009 and 2014 were retrospectively identified through a multi-institutional medical records review. Surgery was performed via a single-port device placed through a 1.5- to 3.0-cm abdominal incision either at the region of the umbilicus or caudal to the right 13th rib. The cryptorchidectomy was performed with graspers, a bipolar vessel sealing device, and a 30° telescope.
  
  
  RESULTS
  SPLC was performed with a single-incision laparoscopic surgery port (n = 15), a multitrocar wound-retractor access system (8), or a metal resterilizable single-port access device (2). Median age was 365 days (range, 166 to 3,285 days). Median body weight was 18.9 kg (41.6 lb; range, 1.3 to 70 kg [2.9 to 154 lb]). Median surgical time was 38 minutes (range, 15 to 70 minutes). Thirty-two testes were removed (12 left, 6 right, and 7 bilateral). Four patients had 1 additional abdominal surgical procedure performed concurrently during SPLC. No intraoperative or postoperative complications were encountered.
  
  
  CONCLUSIONS
  Results suggested that SPLC can be performed in a wide range of dogs and cats with cryptorchidism and can be combined with other elective laparoscopic surgical procedures. The SPLC technique was associated with a low morbidity rate and provided a potentially less invasive alternative to traditional open and multiport laparoscopic techniques.
