RESUMO
The evaluation of preventivemeasures and risk factors for anastomotic leakage has been a constant concern among colorectal surgeons. In this context, the description of a new way to perform a colorectal, coloanal or ileoanal anastomosis, known as transanal transection and single-stapled (TTSS) anastomosis, deserves an appreciation of its qualities, and a discussion about its properties and technical details. In the present paper, the authors review themost recent efforts aiming to reduce anastomotic dehiscence, and describe the TTSS technique in a patient submitted to laparoscopic total proctocolectomy with ileal pouch-anal anastomosis for familial adenomatous polyposis. Surgical perception raises important advantages such as distal rectal transection under visualization, elimination of double-stapling lines (with cost-effectiveness and potential protection against suture dehiscence), elimination of dog ears, and the opportunity to be accomplished via a transanal approach after open, laparoscopic, or robotic colorectal resections. Future studies to confirm these supposed advantages are needed. (AU)

To investigate the discrepancy between the distal resection margin (DRM) assessed by surgeons and pathologists, and the impact of neoadjuvant chemoradiotherapy (nCRT) on DRM. This study included 67 rectal cancer patients undergoing elective surgery. DRMs were assessed through four different techniques: in vivo subjective estimative, made by the surgeon before the rectal resection (by palpation and visual estimative); in vivo objective, measured with a ruler before the rectal transection; ex vivo objective, measured right after resection of the specimen; post-fixation objective measurement, conducted by the pathologist. The DRMs subjectively and objectively assessed by the surgeons were not significantly different (3.40 cm vs. 3.45 cm). There was a mean reduction in the length of DRMs of 35.6%, from 3.45 cm objectively measured by the surgeon to 2.20 cm measured by the pathologist. This difference was significant among patients that did not receive nCRT (3.90 cm vs. 2.30 cm, P < 0.001), but not among those who received nCRT (2.30 vs. 2.05 cm). Surgeons are accurate in assessing rectal cancer DRMs. There are significant differences between intraoperative measurements of DRMs and the final pathologic results. However, these differences are not seen when nCRT is used, a finding that may be useful when sphincter preservation is being considered.

Introducción: A pesar de que la evidencia actual respalda ampliamente el abordaje laparoscópico para las resecciones de colon y recto en función de su seguridad y resultados oncológicos, el desarrollo y adopción del mismo ha sido lento y aún hoy no es de rutina en la mayoría de los centros. Se presenta la experiencia inicial en la Clínica Quirúrgica 2 del Hospital Maciel. Métodos: Estudio retrospectivo que comprende 41 resecciones laparoscópicas en el período 2016-2018. Resultados: El tiempo operatorio medio fue de 3 h para las colectomías y 4 h para las resecciones de recto. El porcentaje de conversión fue de 10%, la falla de sutura del 12% y la mortalidad a 30 días del 13%. Discusión: El abordaje laparoscópico para la colectomía y resección de recto es seguro y con aceptables resultados oncológicos de acuerdo a nuestros resultados. La curva de aprendizaje se sustenta en el volumen anual de cirugías, la realización de otros procedimientos de laparoscopía avanzada y el entrenamiento en simuladores. Conclusiones: nuestra experiencia muestra resultados inmediatos similares a los reportados en la literatura nacional, aunque el tiempo seguimiento aún es insuficiente para analizar los resultados oncológicos a largo plazo.
Introduction: Although current evidence widely supports the laparoscopic approach for resections of the colon and rectum according to their safety and oncological results, the development and adoption of the same has been slow and even today is not routine in most centers. The initial experience is presented in the Surgical Clinic 2 of the Maciel Hospital. Methods: A retrospective study comprising 41 laparoscopic resections in the period 2016-2018. Results: The mean operative time was 3 hours for colectomies and 4 hours for rectal resections. The conversion rate was 10%, the suture failure was 12% and the 30-day mortality was 13%. Discussion: The laparoscopic approach for colectomy and rectal resection is safe and with acceptable oncological results according to our results. The learning curve is based on the annual volume of surgeries, the performance of other advanced laparoscopy procedures and training in simulators. Conclusions: our experience shows immediate results similar to those reported in the national literature, although the follow-up time is still in sufficient to analyze the long-termoncological results.
Introdução: Embora as evidências atuais apóiem amplamente a abordagem laparoscópica para ressecções do cólon e do reto de acordo com sua segurança e resultados ontológicos, o desenvolvimento e a adoção dos mesmos têm sido lentos e até hoje não é rotineiro na maioria dos casos os centros. A experiência inicial é apresentada na Clínica Cirúrgica 2 do Hospital Maciel. Métodos: Estudo retrospectivo com 41 ressecções laparoscópicas no período 2016-2018. Resultados: O tempo operatório médio foi de 3 horas para colectomias e 4 horas para ressecções retais. A taxa de conversão foi de 10%, a falha na sutura foi de 12% e a mortalidade em 30 dias foi de 13%. Discussão: A abordagem laparoscópica para a colectomia e ressecção retal é segura e com resultados ontológicos aceitáveis de acordo com nossos resultados. A curva de aprendizado é baseada no volume anual de cirurgias, no desempenho de outros procedimentos avançados de laparoscopia e no treinamento em simuladores. Conclusões: nossa experiência mostra resultados imediatos semelhantes aos relatados na literatura nacional, embora o tempo de seguimento ainda seja insuficiente para analisar os resultados ontológicos em longo prazo.

RESUMEN Introducción: La resección anterior del recto ultrabaja laparoscópica con anastomosis coloanal evita la realización una colostomía definitiva. Objetivo: Determinar las indicaciones, describir la técnica quirúrgica y mostrar los resultados a largo plazo obtenidos en la realización de este proceder en el tratamiento del cáncer del recto bajo. Método: Se realizó un estudio observacional descriptivo y prospectivo de 53 pacientes con cáncer del recto bajo en el período comprendido entre octubre 2007 y noviembre 2018 en el Centro Nacional de Cirugía de Mínimo Acceso. Todas las resecciones fueron llevadas a cabo por un grupo dedicado a la cirugía colorrectal, en todos los casos se realizó la excisión total del mesorrecto. Resultados: Se operaron mediante esta técnica 53 pacientes, 30 masculinos y 23 femeninos con un promedio de edad de 57 años (rango 23-81) y de ellos 42 (79,2 por ciento) después de terapia neoadyuvante. El promedio de tiempo quirúrgico fue de 195 min (rango 90-360) y las pérdidas hemáticas estimadas, de 72 mL. La incidencia de morbilidad mayor fue de 16,9 por ciento (9/53) y la media de estadía hospitalaria de 6,3 días. La media del periodo de seguimiento fue de 40 meses (rango 1-132) con una recidiva local de 9,4 por ciento (5/53) y una supervivencia global a los 5 años de 80,3 por ciento. Conclusiones: La resección anterior del recto ultrabaja laparoscópica con anastomosis coloanal es una técnica segura con excelentes resultados en cuanto a recidiva local y supervivencia global(AU)
ABSTRACT Introduction: Laparoscopic ultralow anterior rectal resection with coloanal anastomosis prevents the performance of a definitive colostomy. Objective: To determine the indications, describe the surgical technique and show the long-term outcome of performing this procedure in the treatment of cancer of the lower rectum. Method: A descriptive and prospective observational study of 53 patients with low rectal cancer was carried out in the period between October 2007 and November 2018, at the National Center for Minimum Access Surgery. All resections were carried out by a group dedicated to colorectal surgery. In all cases, the total mesorectal excision was performed. Results: 53 patients (30 males and 23 females), with an average age of 57 years (range 23-81) and 42 (79.2 percent) after neoadjuvant therapy were operated using this technique. The average surgical time was 195 min (range 90-360) and the estimated blood loss was 72 mL. The incidence of major morbidity was 16.9 percent (9/53) and the average hospital stay was 6.3 days. The mean follow-up period was 40 months (range 1-132), with a local relapse of 9.4 percent (5/53) and a 5-year overall survival of 80.3 percent. Conclusions: Laparoscopic ultralow anterior resection of the rectum with coloanal anastomosis is a safe technique with excellent outcomes in terms of local relapse and overall survival(AU)
