Purpose:The controversy regarding whether loop ileostomy or loop transverse colostomy is a better method for temporary decompression of colorectal anastomosis motivated this review. Methods: Five randomized trials were included, with 334 patients: 168 in the loop ileostomy group and 166 in the loop transverse colostomy group. The outcomes analyzed were: 1. Mortality; 2. Wound infection; 3. Time of stoma formation; 4. Time of stoma closure; 5. Time interval between stoma formation and closure; 6. Stoma prolapse; 7. Stoma retraction; 8. Parastomal hernia; 9. Parastomal fistula; 10. Stenosis; 11. Necrosis; 12. Skin irritation; 13. Ileus; 14. Bowel leakage; 15. Reoperation; 16. Patient adaptation; 17. Length of hospital stay; 18. Colorectal anastomotic dehiscence; 19. Incisional hernia; 20. Postoperative bowel obstruction. Results: Stoma prolapse was statistically significant (p = 0.00001), but with statistical heterogeneity; the sensitive analysis was applied, excluding the trials that included emergency surgery, and this showed: p = 0.02, with I 2 = 0% for the heterogeneity test. Conclusions: The outcomes reported were not statistically or clinically significant except for stoma prolapse. Better evidence for making the choice between loop ileostomy or loop colostomy requires large-scale randomized controlled trials. Key words: Ileostomy. Colostomy. Colorectal surgery. Systematic review. Meta-analysis. RESUMO Objetivo:A controvérsia entre ileostomia em alça ou colostomia em alça como a melhor forma para a descompressão temporária da anastomose colorretal motivou a realização desta revisão. Métodos: Cinco ensaios clínicos casualizados foram incluídos com 334 pacientes: 168 no grupo de ileostomia e 166 no grupo de colostomia. Os resultados analisaram: 1. Mortalidade; 2. Infecção da ferida; 3. Tempo de formação do estoma; 4. Tempo de fechamento do estoma; 5. Intervalo de tempo entre a formação e o fechamento do estoma; 6. Prolapso do estoma; 7. Retração do estoma; 8. Hérnia parastomal; 9. Fistula parastomal; 10. Estenose; 11. Necrose; 12. Irritação de pele; 13. Íleo; 14. Fístula entérica; 15. Reoperação; 16. Adaptação do paciente; 17. Tempo de internação hospitalar; 18. Deiscência da anastomose colorretal; 19. Hérnia de Incisional; 20. Obstrução intestinal pós-operatória. Resultados: Prolapso do estoma: p = 0.00001, mas com heterogeneidade estatística; a análise de sensibilidade foi aplicada excluindo os estudos que incluíram cirurgias de emergência: p = 0.02 e teste de heterogeneidade: I 2 =0%. Conclusões: Os resultados encontrados não foram estatística ou clinicamente significantes, exceto prolapso do estoma. A melhor evidência para a escolha entre ileostomia em alça ou colostomia em alça necessita de maior número de ensaios clínicos.

BackgroundAmong the many challenges in cancer diagnosis is the early distinction between metastatic cancer and a secondary tumor. This difficulty stems from the lack of markers that offer high sensitivity and specificity and can be easily applied in routine laboratory work. An example of this challenge is distinguishing gastric metastases originating from breast cancer from a gastric primary tumor. Hepatocyte nuclear factor 4 alpha (HNF4A) has been suggested as a potential marker in these cases.The aim of this study was to analyze the expression of HNF4A, estrogen receptor (ER), progesterone receptor (PR) and gross cystic disease fluid protein 15 (GCDFP-15) in a Brazilian cohort.MethodsWe performed immunohistochemistry analysis of HNF4A, ER, PR and GCDFP-15 in 126 patients divided into three cohorts: primary breast cancer, primary gastric cancer and both types of tumors.ResultsOur data confirmed the sensitivity and specificity of the HNF4A marker compared to other currently used clinical markers.ConclusionHNF4A alone could be a gold standard marker for distinguishing primary gastric cancer from breast metastasis, thus validating its potential clinical use, especially in populations with high genetic diversity.Electronic supplementary materialThe online version of this article (doi:10.1186/s13000-017-0635-2) contains supplementary material, which is available to authorized users.
