ABSTRACT

BACKGROUND:

This study aimed to assess the best achievable outcomes in laparoscopic liver resection (LLR) after risk adjustment based on surgical technical difficulty using a national registry.

METHODS:

LLRs registered in the Italian Group of Minimally Invasive Liver Surgery registry from November 2014 to March 2018 were considered. Benchmarks were calculated according to the Achievable Benchmark of Care (ABC™). LLRs at each centre were divided into three clusters (groups I, II and III) based on the Kawaguchi classification. ABCs for overall and major morbidity were calculated in each cluster. Multivariable analysis was used to identify independent risk factors for overall and major morbidity. Significant variables were used in further risk adjustment.

RESULTS:

A total of 1752 of 2263 patients fulfilled the inclusion criteria 1096 (62·6 per cent) in group I, 435 (24·8 per cent) in group II and 221 (12·6 per cent) in group III. The ABCs for overall morbidity (7·8, 14·2 and 26·4 per cent for grades I, II and II respectively) and major morbidity (1·4, 2·2 and 5·7 per cent) increased with the difficulty of LLR. Multivariable analysis showed an increased risk of overall morbidity associated with multiple LLRs (odds ratio (OR) 1·35), simultaneous intestinal resection (OR 3·76) and cirrhosis (OR 1·83), and an increased risk of major morbidity with intestinal resection (OR 4·61). ABCs for overall and major morbidity were 14·4 and 3·2 per cent respectively for multiple LLRs, 30 and 11·1 per cent for intestinal resection, and 14·9 and 4·8 per cent for cirrhosis.

CONCLUSION:

Overall morbidity benchmarks for LLR ranged from 7·8 to 26·4 per cent, and those for major morbidity from 1·4 to 5·7 per cent, depending on complexity. Benchmark values should be adjusted according to multiple LLRs or simultaneous intestinal resection and cirrhosis.
RESUMEN
ANTECEDENTES Este estudio tuvo como objetivo evaluar los mejores resultados que se pueden conseguir en la resección hepática laparoscópica (laparoscopic liver resection, LLR) después del ajuste por riesgos basado en la dificultad de la técnica quirúrgica utilizando un registro nacional.

MÉTODOS:

Se consideraron las LLRs incluidas en el Registro del Grupo Italiano de Cirugía Hepática Mínimamente Invasiva desde 11/2014 a 03/2018. Los resultados de referencia (benchmarks) se calcularon de acuerdo con el Achievable Benchmark of Care (ABC™). Las LLRs de cada uno de los centros se dividieron en 3 grupos (Grupo I, II y III) en base a la clasificación de Kawaguchi. Se calculó el ABC de la morbilidad global y de la morbilidad mayor para cada grupo. Se realizó un análisis multivariable para identificar los factores independientes de riesgos para la morbilidad global y morbilidad mayor. Se utilizaron variables significativas para realizar ajustes de riesgo adicionales.

RESULTADOS:

Un total de 1.752 pacientes de los 2.263 cumplían los criterios de inclusión, de los cuales 1.096 (62,6%) se incluyeron en el Grupo I, 435 (24,8%) en el Grupo II y 221 (12,6%) en el Grupo III. El ABC de la morbilidad global (7,8%, 14,2%, 26,4%) y de la morbilidad mayor (1,4%, 2,2%, 5,7%) aumentó del Grupo I al Grupo III. El análisis multivariable mostró un incremento del riesgo para la morbilidad global asociada con múltiples LLRs (razón de oportunidades, odds ratio, OR 1,349), resección intestinal simultánea (OR 3,760) y cirrosis (OR 1,825), y para la morbilidad mayor con la resección intestinal (OR 4,606). Los ABC de la morbilidad global y morbilidad mayor fueron 14,4% y 3,2% para las LLR múltiples, 30% y 11% para la resección intestinal, y 14,9% y 4,8% para la cirrosis, respectivamente.

CONCLUSIÓN:

Los resultados de referencia (benchmark) para la morbilidad global y morbilidad mayor en la LLR variaron entre un 8% y un 26% y entre un 1,4% y un 5,7%, dependiendo de la complejidad. Los valores de referencia deberían ajustarse de acuerdo con la práctica de LLRs múltiples o resección intestinal simultánea y cirrosis.
