Single-Port Colectomy vs Multi-Port Laparoscopic Colectomy. Systematic Review and Meta-Analysis of More Than 2800 Procedures

ObjectiveMultiport laparoscopic surgery in colon pathology has been demonstrated as a safe and effective technique. Interest in reducing aggressiveness has led to other procedures being described, such as SILS. The aim of this meta-analysis is to evaluate feasibility and security of SILS technique in colonic surgery.Material and methodsA meta-analysis of 27 observational studies and one prospective randomised trial has been conducted by the use of random-effects models.ResultsA total amount of 2870 procedures was analysed: 1119 SILS and 1751 MLC. We did not find statistically significant differences between SILS and MLC in age (WMD 0.28 [−1.13, 1.68]; P=.70), BMI (WMD −0.63 [−1.34, 0.08]; P=.08), ASA score (WMD −0.02 [−0.08, 0.04]; P=.51), length of incision (WMD −1.90 [−3.95, 0.14]; P=.07), operating time (WMD −2.69 (−18.33, 12.95]; P=.74), complications (OR=0.89 [0.69, 1.15]; P=.37), conversion to laparotomy (OR=0.59 [0.33, 1.04]; P=.07), mortality (OR=0.91 [0.36, 2.34]; P=.85) or number of lymph nodes harvested (WMD 0.13 [−2.52, 2.78]; P=.92). The blood loss was significantly lower in the SILS group (WMD −42.68 [−76.79, −8.57]; P=.01) and the length of hospital stay was also significantly lower in the SILS group (WMD −0.73 [−1.18, −0.28]; P=.001).ConclusionSingle-port laparoscopic colectomy is a safe and effective technique with additional subtle benefits compared to multiport laparoscopic colectomy. However, further prospective randomised studies are needed before single-port colectomy can be considered an alternative to multiport laparoscopic surgery of the colon.

ResumenObjetivosLa cirugía laparoscópica multipuerto (CLM) ha demostrado su seguridad y efectividad en la cirugía del colon. Con la intención de reducir la agresividad surgen otras técnicas como la cirugía por puerto único (SILS). El objetivo de este metaanálisis es evaluar la seguridad y la viabilidad de la técnica SILS en la cirugía del colon.Material y métodosSe realiza un metaanálisis de 27 estudios observacionales y uno prospectivo aleatorizado mediante el modelo de efectos aleatorios.ResultadosSe han analizado 2.870 procedimientos: 1.119 SILS y 1.751 CLM. No se han encontrado diferencias estadísticamente significativas en la edad (DMP 0,28 [−1,13, 1,68]; p = 0,70), IMC (DMP −0,63 [−1,34, 0,08]), ASA (DMP −0,02 [−0,08, 0,04]; p = 0,51), longitud de incisión (DMP −1,90 [−3,95, 0,14]; p = 0,07), tiempo operatorio (DMP −2,69 [−18,33, 12,95]; p = 0,74), complicaciones (OR = 0,89 [0,69, 1,15]]; p = 0,37), conversión a laparotomía (OR = 0,59 [0,33, 1,04]; p = 0,07), mortalidad (OR = 0,91 [0,36, 2,34]; p = 0,85) o número de ganglios obtenidos (DMP 0,13 [−2,52, 2,78]; p = 0,92). La pérdida de sangre (DMP −42,68 [−76,79, −8,57]; p = 0,01) y la estancia hospitalaria (DMP −0,73 [−1,18, −0,28]; p = 0,001) son significativamente menores en el grupo SILS.ConclusionesLa cirugía colorrectal mediante SILS es segura y efectiva, con ligeros beneficios respecto a la CLM. Sin embargo, se necesitan más estudios aleatorizados antes de que la SILS se pueda considerar una alternativa a la CLM.
