Antecedentes: La enfermedad por coronavirus-19 (COVID-19) ha forzado cambios en todas las facetas de los sistemas de salud. En este artículo se describen las modificaciones realizadas en la Sección de Cirugía Miniinvasiva Guiada por Imágenes (CIGIM) del Hospital Italiano de Buenos Aires, para promover la seguridad y el bienestar del personal manteniendo la capacidad de respuesta a la demanda asistencial y académica. Material y métodos: Las medidas incluyeron la reorganización del personal, el manejo de los procedimientos electivos y de urgencia, las consultas ambulatorias, así como la actividad docente y de investigación. También se analizó comparativamente la variación interanual (2019-2020) de los pacientes atendidos (procedimientos percutáneos y consultas ambulatorias) entre el 20 de marzo y el 10 de mayo de cada año. Resultados: La Sección CIGIM fue reorganizada en rotaciones semanales de 3 actividades, con distanciamiento estricto entre sus miembros, y hasta el momento ninguno resultó afectado. Los pacientes operados y las consultas realizadas durante el período estudiado 2019 vs. 2020 disminuyeron significativamente: 136 vs. 57 operados y 102 vs. 39 consultas; p < 0,0001. Las plataformas virtuales se utilizaron con éxito para mantener la actividad de pregrado, incluyendo cursadas de alumnos de grado de Medicina de dos universidades, el programa de residencia de Cirugía General y reuniones científicas; en dicho período se produjeron 3 trabajos científicos para publicación. Conclusiones: La disminución de la demanda asistencial, la reorganización de los grupos de trabajo y las plataformas virtuales pueden resultar estrategias y herramientas valiosas para afrontar la pandemia por COVID-19.

Background: Coronavirus-19 disease (COVID-19) has forced changes in all facets of health systems. This article describes the modifications made in the Image-Guided Minimally Invasive Surgery Section (CIGIM) of the Hospital Italiano de Buenos Aires, to promote the safety and well being of personnel while maintaining the ability to respond to academic and healthcare demand. Material and methods: Measures included reorganization of staff, management of elective and emergency procedures, outpatient consultations, as well as teaching and research activity. The inter-annual variation (2019-2020) of the patients attended (percutaneous procedures and outpatient consultations) between March 20 and May 10 of each year was also analyzed comparatively. Results: The CIGIM Section was reorganized into weekly rotations of 3 activities, with strict distancing among its members, and so far none have been affected. The operated patients and the consultations made during the analyzed period of 2019 vs. 2020 decreased significantly: 136 vs. 57 operated and 102 vs. 39 consultations; p <0.0001. Virtual platforms were successfully used to maintain undergraduate activity, including courses taken by medical students from two universities, the General Surgery residency program and scientific meetings; In this period, 3 scientific papers were written for publication. Conclusions: Dealing with healthcare demand, reorganizing working groups and virtual platforms can be valuable strategies and tools to confront the COVID-19 pandemic.

Hepatobiliary scintigraphy to evaluate liver function in associating liver partition and portal vein ligation for staged hepatectomy: Liver volume overestimates liver function.

BACKGROUND: Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) induces a rapid and extensive increase in liver volume. The functional quality of this hypertrophic response has been called into question because ALPPS is associated with a substantial incidence of liver failure and high perioperative mortality. This multicenter study aimed to evaluate functional liver regeneration in contrast to volumetric liver regeneration in ALPPS, using technetium-99m hepatobiliary scintigraphy and computed tomography volumetry, respectively. METHODS: Patients who underwent ALPPS and hepatobiliary scintigraphy in 6 centers were included. Hepatobiliary scintigraphy data were analyzed centrally at the Academic Medical Center in Amsterdam according to established protocols. Increase in liver function as measured by hepatobiliary scintigraphy after stage 1 of ALPPS was compared with the increase in liver volume. In addition, we analyzed the impact of liver function and volume on postoperative outcomes including liver failure, morbidity, and mortality. RESULTS: In 60 patients, future liver remnant volume increased by a median 78% (interquartile range 48-110) during a median 8 (interquartile range 6-14) days after stage 1, while function as measured by hepatobiliary scintigraphy increased by a median 29% (interquartile range 1-55) throughout 7 days (interquartile range 6-10) in the 27 patients with paired measurements. After stage 2 of ALPPS, liver failure occurred in 5/60 (8%) patients, severe complications in 24/60 (40%), and mortality occurred in 4/60 (7%). CONCLUSION: In ALPPS, volumetry overestimates liver function as measured by hepatobiliary scintigraphy and may be responsible for the high rate of liver failure. Quantitative liver function tests are highly recommended to avoid post hepatectomy liver failure.

Survival after associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) for advanced colorectal liver metastases: A case-matched comparison with palliative systemic therapy.

BACKGROUND: Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) allows the resection of colorectal liver metastases with curative intent which would otherwise be unresectable and only eligible for palliative systemic therapy. This study aimed to compare outcomes of ALPPS in patients with otherwise unresectable colorectal liver metastases with matched historic controls treated with palliative systemic treatment. METHODS: All patients with colorectal liver metastases from the international ALPPS registry were identified and analyzed. Survival data were compared according to the extent of disease. Otherwise unresectable ALPPS patients were defined by at least 2 of the following criteria: ≥6 metastasis, ≥2 future remnant liver metastasis, ≥6 involved segments excluding segment 1. These patients were matched with patients included in 2, phase 3, metastatic, colorectal cancer trials (CAIRO and CAIRO2) using propensity scoring in order to compare survival. RESULTS: Of 295 patients with colorectal liver metastases in the ALPPS registry, 70 patients had otherwise unresectable disease defined by the proposed criteria. Two-year overall survival was 49% and 72% for patients with ≥2 and <2 criteria, respectively (P = .002). Median disease-free survival was 6 months compared to 12 months (P < .001) in the ≥2 and <2 criteria groups, respectively. Median overall survival was comparable between ALPPS patients with ≥2 criteria and case-matched patients who received palliative treatment (24.0 vs 17.6 months, P = .088). CONCLUSION: Early oncologic outcomes of patients with advanced liver metastases undergoing ALPPS were not superior to results of matched patients receiving systemic treatment with palliative intent. Careful patient selection is essential in order to improve outcomes.
