Although smaller circular staplers are easier to insert and less likely to involve the vagina and levator ani muscles when performing double stapling technique anastomosis, surgeons often consider that larger circular staplers would be safer in reducing the risk of postoperative anastomotic strictures. This study aimed to investigate the safety of using 25-mm circular staplers compared with 28/29-mm staplers in the double stapling technique anastomosis regarding the development of anastomotic strictures and other complications. This is a retrospective observational study. This study was conducted at a single comprehensive cancer center. Consecutive patients undergoing curative colorectal resection with double stapling technique anastomosis for stage I to III sigmoid colon and rectal cancer between 2013 and 2016 were included. The incidence of anastomotic complications (strictures, leakage, and bleeding) was compared between the 25- and 28/29-mm circular staplers. Predictors for anastomotic strictures were investigated with multivariable logistic regression. Small (25-mm) staplers were used in 186 (22.8%) of 815 eligible patients. The 25-mm staplers were associated with use in female patients, splenic flexure take down, high tie of the inferior mesenteric artery, and low anastomosis. Overall anastomotic complications (11.8% vs 13.7%, p = 0.51), strictures (5.9% vs 3.3%, p = 0.11), leakage (2.7% vs 3.8%, p = 0.47), and bleeding (4.8% vs 7.6%, p = 0.19) were not different between the 25- and 28/29-mm staplers. From multivariable logistic regression, independent predictors of anastomotic strictures included diverting ostomy and anastomotic leakage, but not small circular stapler use. Most of the 32 anastomotic strictures were successfully treated without surgical intervention (finger dilation, n = 25; endoscopic intervention, n = 5). This was a single-center retrospective study. Use of 25-mm circular staplers for double stapling technique anastomosis is safe and does not increase the risk of anastomotic strictures and other anastomotic complications in comparison with larger staplers.

ANTECEDENTES:Aunque las engrapadoras circulares más pequeñas son más fáciles de insertar y menos probable que involucren a la vagina y los músculos elevadores del ano, cuando se realiza una anastomosis con técnica de doble engrapado, frecuentemente los cirujanos consideran que las engrapadoras circulares más grandes, serían más seguras para disminuir los riesgos de estenosis anastomóticas postoperatorias.OBJETIVO:El estudio se dirigió para investigar la seguridad en el uso de engrapadoras circulares de 25 mm, en comparación con engrapadoras de 28/29 mm, en anastomosis con técnica de doble engrapado, en relación al desarrollo de estenosis anastomóticas y otras complicaciones.DISEÑO:Estudio observacional retrospectivo.AJUSTE:Centro oncológico integral único.PACIENTES:Se incluyeron pacientes consecutivos sometidos a resección colorrectal curativa, con anastomosis y técnica de doble engrapado, para cáncer de recto y colon sigmoide en estadios I-III entre 2013 y 2016.PRINCIPALES MEDIDAS DE RESULTADO:Se compararon las incidencias de complicaciones anastomóticas (estenosis, fugas y sangrados) entre las engrapadoras circulares de 25 y 28/29 mm. Los predictores para estenosis anastomóticas se investigaron con regresión logística multivariable.RESULTADOS:Entre un total de 815 pacientes elegibles, se utilizaron engrapadoras de 25 mm en 186 (22,8%). Las engrapadoras de 25 mm se asociaron con el uso en pacientes femeninas, descenso del ángulo esplénico, ligadura alta de arteria mesentérica inferior y anastomosis baja. Complicaciones anastomóticas generales (11,8% vs. 13,7%, p = 0,51), estenosis (5,9% vs. 3,3%, p = 0,11), fugas (2,7% vs. 3,8%, p = 0,47) y sangrado (4,8% vs. 7,6%, p = 0,19). No hubo diferencia entre las engrapadoras de 25 y 28/29 mm. En la regresión logística multivariable, predictores independientes de estenosis anastomóticas incluyeron ostomía derivativa y fuga anastomótica, pero no incluyeron el uso de engrapadoras circulares pequeñas. La mayoría de las 32 estenosis anastomóticas se trataron con éxito sin intervención quirúrgica (dilatación del dedo, n = 25; intervención endoscópica, n = 5).LIMITACIONES:Fue un estudio retrospectivo de un solo centro.CONCLUSIONES:El uso de engrapadoras circulares de 25 mm para la anastomosis con técnica de doble engrapado, es seguro y no aumenta el riesgo de estenosis anastomóticas y de otras complicaciones anastomóticas, cuando son comparadas con engrapadoras más grandes.
