COMPARATIVE STUDY
JOURNAL ARTICLE
Postoperative pain and cosmetic results of minilaparoscopic nephrectomy compared to the conventional technique.
Actas urologicas españolas. 2019 April
INTRODUCTION: In recent years urology has been focussing on less invasive forms of laparoscopy with less impact on the abdominal wall. The minilaparoscopy (ML) is promising in this regard. Our objective is to compare the results of a series of patients who underwent minilaparoscopic nephrectomy with another series who underwent conventional laparoscopy (CL).
MATERIAL AND METHODS: We chose 8 nephrectomies performed by mini-laparoscopy in a single hospital (NmL group) from a total of 110 patients included in multiple centres and compared them retrospectively with a contemporary series of 16 patients who underwent CL (NL group). From 1 to 3 3mm and 5mm trocars were used for the NmL and the NL, respectively, one 10mm trocar in the pararectal edge of a Pfannenstiel incision and another 11mm paraumbilical trocar for the optics. Age, BMI, ASA, complications, analgesic requirements in the postoperative period and cosmetic satisfaction were recorded using the Patient Scar Assessment Questionnaire (PSAQ), one month after the intervention.
RESULTS: Both groups were comparable and there were no differences in terms of surgery time, number of ports used, hospital stay or intra-and postoperative complications. In only one patient from the NmL group, a 3mm trocar had to be replaced by a 5mm trocar and one patient in the NL group was converted to hand-assisted surgery due to severe adherences. The patients in the NmL group had less postoperative pain on the VAS (±0 vs. 4±25, P=.05) and were more satisfied with their appearance on the PSAQ (8.5±1.4 vs. 16.6±3.1, P=.05) compared to the NL group.
CONCLUSIONS: The results obtained with the ML instrument were similar to those obtained by CL, but with the advantages of less postoperative pain and better cosmetic results.
