RESUMEN

AIM: The correct analysis of lymph node status is one of the most important parameters for the accurate pathological diagnosis of colorectal cancer. Our aim was to evaluate the number of lymph nodes among the specimens obtained from colorectal resections due to colorectal cancer, before and after the routine use of a lymph node revealing solution (LNRS). METHOD: Data from 780 surgical specimens from patients of both genders with colorectal cancer were studied. The cases were divided chronologically into two groups: the conventional group included 497 specimens treated with conventional methods, i.e. without the use of the LNRS (January 2000 to July 2007), and the LNRS group included 283 specimens examined through the routine use of this solution (August 2007 to July 2012). RESULTS: Most patients were female (57.4%) with a median age of 62 years. The median lymph node number was 18, and 75.9% of the cases (592) had 12 or more nodes dissected. Lymph node metastases were noted in 334 cases (42.8%). A median of 24 lymph nodes was dissected in the LNRS group compared to 15 in the conventional group (P < 0.001). The LNRS group had 9.2% of cases with fewer than 12 lymph nodes dissected compared with 32.6% in the conventional group (P < 0.001). CONCLUSIONS: The use of the LNRS increases the number of lymph nodes obtained from colorectal cancer surgical specimens and can help to reduce the number of cases with < 12 lymph nodes.

RESUMEN

Background and aims: Early oral feeding after colorectal resections is one of the many factors that contributes to enhance recovery after surgery, mainly impacting on postoperative ileus. The aim of this study was to evaluate the impact of early postoperative oral feeding in patients undergoing elective colorectal resection. Methods: Patients were randomly assigned to either a conventional postoperative dietary regimen or a free diet on the first postoperative day. Results: Altogether 29 patients were enrolled. Clinical characteristics were similar in both groups. Good nutritional status was seen in 86% of patient in the traditional care (TRAD) group versus 46% in the early fed (EF) group (p<0.05). There was no difference between groups in terms of procedures. Median hospital stay was 5.0 days in the TRAD group versus 3.0 days in the EF group(p<0.05). Complication rates and acceptance of diet were similar in both groups. Diarrhea occurred more frequently in the TRAD group (OR=1.86; IC95%:1.08-3.20).Conclusion: Early oral intake is well tolerated, leads to significant shorter hospital stay and does not increase complications (AU)

Antecedentes y objetivos: La alimentación oral precoztras las resecciones colorrectales es uno de los muchos factores que contribuyen a favorecer la recuperación tras la cirugía, teniendo sobre todo una influencia en el íleoposoperatorio. El propósito de este estudio fue evaluar el impacto de la alimentación oral precoz posoperatoria en pacientes sometidos a resección colorrectal programada. Métodos: Se distribuyó al azar a los pacientes para recibir un régimen alimenticio pos operatorio convenciona lo una dieta libre en el primer día de posoperatorio. Resultados: Se reclutó a un total de 29 pacientes. Las características clínicas fueron similares en ambos grupos. Se observó buen estado nutritivo en el 86% de los pacientes con la atención tradicional (TRAD) frente al 46% en el grupo con alimentación precoz (EF) (p < 0,05). No hubo diferencias entre los grupos con respecto a los procedimientos. La estancia media hospitalaria fue de 5,0 días en el grupo TRAD frente a 3,0 días en el grupo EF (p < 0,05). Las tasas de complicación y aceptación de la dieta fueron similares en ambos grupos. La diarrea ocurrió más frecuentemente en el grupo TRAD (OR = 1,86; IC95%: 1,08-3,20).Conclusión: La alimentación oral precoz se tolera bien, conlleva una estancia hospitalaria más corta y no aumenta las complicaciones (AU)
