title: [Use of percutaneous needles in the feasability of single-port laparoscopic cholecystectomy].
abstract: BACKGROUND
  The usefulness of percutaneous needles (PN) to replace traditional assistance ports in mini-invasive techniques with a single port is analyzed and their feasibility for conducting a single port laparoscopic cholecystectomy (SPLC) is demonstrated.
  
  
  METHODS
  A retrospective, linear and descriptive study covering 2,431 patients with a diagnosis of acute and non-acute gallbladder disease has been conducted. The patients underwent a single port laparoscopic cholecystectomy using some type of PNs, replacing the assisting ports used in traditional laparoscopic cholecystechtomy (TLC). Based on the progressive use of PNs-reins (R), hooked needles (HN) and passing suture needles (PSN)-to carry out the SPLC technique, 3 groups have been established: A, B and C. The results were compared using a Student T test, odds ratio and CI and were analyzed by means of the SPSS software v. 13.0.
  
  
  RESULTS
  The use of PNs showed an increased feasibility for the laparoscopic procedure, as they were included in the surgical technique. The R were useful when carrying out the SPLC in 78% of the cases and when the HK were added, the results increased to 88%. When using the 3 types (R, HN and PSN), the results increased by 96%. Statistical significance was obtained with these values: chi 2=67.13 and P<.001; odds ratio and 95% CI became significant when comparing the B/C, A/C, and A-B/C groups.
  
  
  CONCLUSIONS
  The PNs, replacing the assisting ports in laparoscopy, make it possible to attain a feasibility of the process in 96% of the cases. This percentage was similar to what is achieved with the TLC, which places the one port laparoscopy surgery technique as an advantageous and economic alternative. This application of the PNs could be made extensive to other single-port techniques, with a multi-valve platform and natural orifice surgery.
