[Comparación entre ligadura con lazo hemostático y engrapadora mecánica lineal para el cierre de base apendicular]. / Comparison between endoloop and linear mechanical stapler for the appendicular stump closure.

INTRODUCCIÓN: En las últimas décadas es creciente el abordaje por mínima invasión de patologías abdominales debido a sus beneficios evidentes. El cuadro apendicular es la principal emergencia quirúrgica, con diferentes métodos del cierre de la base apendicular. En este artículo comparamos dicho cierre con engrapadora lineal o ligadura con lazo hemostático, para analizar la frecuencia de complicaciones como absceso, dehiscencia y seroma. MÉTODO: Se realizó un estudio prospectivo, observacional y descriptivo, con un total de 703 procedimientos, empleando en 567 pacientes ligadura con lazo hemostático y en 136 engrapadora lineal, operados por los mismos cirujano y equipo quirúrgico, con curva de aprendizaje concluida. RESULTADOS: Las complicaciones referidas en el presente estudio son absceso (n = 5), dehiscencia (n = 3) y seroma (n = 3). De acuerdo con las fases de la patología apendicular: fase 1 o apéndice congestivo, no presentaron complicaciones; fase 2 o supurativo, se reportó un caso de dehiscencia de herida quirúrgica con el uso de ligadura con lazo hemostático; fase 3 o necrótico, se reportó un caso de seroma en un paciente tratado con ligadura con lazo hemostático; y fase 4 o perforado, se encuentra diferencia significativa en el caso de abscesos, reportando cinco con el uso de ligadura con lazo hemostático y ninguno con engrapadora lineal. CONCLUSIONES: En nuestro estudio no existe diferencia estadísticamente significativa entre el uso de engrapadora lineal o ligadura con lazo hemostático en las fases apendiculares 1-3; en la fase 4 es de utilidad significativa el uso de engrapadora lineal ante la incidencia de abscesos. INTRODUCTION: In the last decades, the approach by minimally invasive surgery of abdominal pathologies is growing due to its evident benefits; the appendicular cases being the main surgical emergency, with different methods of closing the appendicular base. In this article, we compared the appendicular base closure with linear stapler and endoloop, to analyze the frequency of complications such as abscess, dehiscence and seroma. METHOD: A prospective, observational and descriptive study was conducted, with a total of 703 procedures, using 567 endoloop patients and 136 linear stapler, operated by the same surgeon and surgical team, with a completed learning curve. RESULTS: The complications referred in the present study were patients with abscess (n = 5), dehiscence (n = 3) and seroma (n = 3). According to the phases of the appendiceal pathology: phase 1 or congestive appendix did not present complications; phase 2 or suppurative was reported one case of surgical wound dehiscence in the use of endoloop; in phase 3 or necrotic, one case of seroma was reported in a patient treated with endoloop; while in phase 4 or perforated there is a significant difference in the case of abscesses, reporting five in the use of endoloop and none in the case of a linear stapler. CONCLUSIONS: In our study there is no statistically significant difference between the use of linear stapler or endoloop in the early appendicular phases; being of significant utility in Phase 4 the use of linear stapler for the incidence of abscesses.

Hepatic Metastasis from Colorectal Cancer.

The liver is the most common site of metastasis in patients with colorectal cancer due to its anatomical situation regarding its portal circulation. About 14 to 18% of patients with colorectal cancer present metastasis at the first medical consultation, and 10 to 25% at the time of the resection of the primary colorectal cancer. The incidence is higher (35%) when a computed tomography (CT) scan is used. In the last decades, a significant increase in the life expectancy of patients with colorectal cancer has been achieved with different diagnostic and treatment programs. Despite these improvements, the presence of metastasis, disease recurrence, and advanced local tumors continue to remain poor prognostic factors. Median survival without treatment is <8 months from the moment of its presentation, and a survival rate at 5 years of 11% is the best prognosis for those who present with local metastasis. Even in patients with limited metastatic disease, 5-year survival is exceptional. Patients with hepatic metastasis of colorectal cancer have a median survival of 5 to 20 months with no treatment. Approximately 20 to 30% of patients with colorectal metastasis have disease confined to the liver, and this can be managed with surgery. Modern surgical strategies at the main hepatobiliary centers have proved that hepatectomy of 70% of the liver can be performed, with a mortality rate of <5%. It is very important to have knowledge of predisposing factors, diagnostic methods, and treatment of hepatic metastasis. However, the establishment of newer, efficient, preventive screening programs for early diagnosis and adequate treatment is vital.
