RESUMO

BACKGROUND: Sentinel lymph node (SLN) biopsy may identify patients who may need completion lymphadenectomy and adjuvant therapy. METHODS: Univariate and multivariate analysis were conducted for SLN status in a prospective cohort of 1,041 patients. A biopsy was recommended for melanoma greater than or equal to 1 mm thick or greater than or equal to .75 mm with poor prognostic features. RESULTS: For sentinel node status, mitotic rate is very significant in univariate analysis. In multivariate analysis, Breslow, lymphovascular invasion, and primary site were significant. Breslow thickness greater than or equal to 2 mm and SLN with macroscopic burden greater than or equal to 2 mm are the only statistically significant variables predicting the non-SLN status in multivariate analysis. CONCLUSIONS: The data confirm the importance of Breslow, lymphovascular invasion, and body site for SLN status. The cutoff of 2 mm for tumor load in SLN appears to be a simple technique to find the high-risk patients with further lymph node disease.

RESUMO

BACKGROUND: Turnbull-Cutait abdominoperineal pull-through followed by delayed coloanal anastomosis (DCA) was first described in 1961. Studies have described its use for challenging colorectal conditions. We reviewed our experience with Turnbull-Cutait DCA as a salvage procedure for complex failure of colorectal anastomosis. METHODS: We performed a retrospective cohort study from October 2010 to September 2011, with analysis of postoperative morbidity and mortality. RESULTS: Seven DCAs were performed for anastomotic complications (3 chronic leaks, 2 rectovaginal fistulas, 1 colovesical fistula, 1 colonic ischemia) following surgery for rectal cancer. Six patients had a diverting ileostomy constructed as part of previous treatment for anastomotic complications before the salvage procedure. No anastomotic leaks were observed. All procedures but 1 were completed successfully. One patient who underwent DCA subsequently required an abdominoperineal resection and a permanent colostomy for postoperative extensive colonic ischemia. No 30-day mortality occurred. CONCLUSION: Salvage Turnbull-Cutait DCA appears to be a safe procedure and could be offered to patients with complex anastomotic complications. This procedure could be added to the surgeon's armamentarium as an alternative to the creation of a permanent stoma.


CONTEXTE: La résection colique abdominale avec extraction trans-anale et anastomose colo-anale différée (CAD) fut décrite initialement par Turnbull et Cutait en 1961. Cette intervention a récemment été rapportée pour le traitement des conditions colorectales complexes. Nous avons revu notre expérience avec la CAD comme chirurgie de sauvetage dans le traitement des complications complexes de l'anastomose colo-anale de première intention. MÉTHODES: Nous avons effectué une étude de cohorte rétrospective entre octobre 2010 et septembre 2011, en analysant la morbidité et la mortalité postopératoires. RÉSULTATS: Sept CAD ont été réalisées en raison de complications anastomotiques (3 fuites anastomotiques chroniques, 2 fistules rectovaginales, 1 fistule colovésicale, 1 ischémie colique) résultant du traitement chirurgical d'un cancer rectal. Six patients avaient subi une iléostomie de dérivation pour fuite anastomotique, dans la période précédant la CAD de sauvetage. À l'exception d'un patient, toutes les procédures se sont soldées en succès. Aucune fuite anastomotique n'a été observée après CAD. Un patient a dû subir une résection abdominopérinéale avec colostomie terminale permanente en raison d'ischémie colique aigue du colon distal après CAD. Aucun décès n'est survenu dans les 30 jours suivant la CAD. CONCLUSION: La CAD de sauvetage apparait comme une intervention sécuritaire qui représente une option thérapeutique valable pour les patients souffrant de complications complexes de fuites anastomotiques colorectales. Cette intervention pourrait s'ajouter à l'arsenal du chirurgien comme alternative à la création d'une stomie permanente.
