Incidence of synchronous appendiceal neoplasm in patients with colorectal cancer and its clinical significance

<p>Abstract</p> <p>Background</p> <p>The aims of this study were to evaluate the incidence of synchronous appendiceal neoplasm in patients with colorectal cancer, and to determine its clinical significance.</p> <p>Methods</p> <p>Pathological reports and medical records were reviewed of patients with colorectal adenocarcinoma who underwent oncological resection of the tumor together with appendectomy at the Faculty of Medicine Siriraj Hospital, Mahidol University, Thailand between September 2000 and April 2008.</p> <p>Results</p> <p>This study included 293 patients with an average age of 62 years (range 19–95) and 51 percent were male. Of the patients studied, 228 (78 percent) had right hemicolectomy, whereas the others (22 percent) had surgery for left-sided colon cancer or rectal cancer. One patient (0.3 percent) had epithelial appendiceal neoplasm (mucinous cystadenoma) and 3 patients (1.0 percent) had metastatic colorectal cancer in the mesoappendix. However, the presence of synchronous appendiceal tumors and/or metastasis did not alter postoperative management, as these patients had received adjuvant therapy and were scheduled for surveillance program because of nodal involvement.</p> <p>Conclusion</p> <p>The incidence of synchronous primary appendiceal neoplasm and secondary (metastatic) appendiceal neoplasm in colorectal cancer patients was 0.3 and 1.0 percent, respectively. However, these findings did not change the postoperative clinical management.</p

Avaliação da função pulmonar em pacientes submetidas à mastoplastia redutora

OBJETIVO: Avaliar prospectivamente a função pulmonar de pacientes submetidas à mastoplastia redutora. MÉTODOS: Doze pacientes femininas portadoras de gigantomastia e sem antecedentes médicos, realizaram mastoplastia redutora no Hospital das Clínicas da UFBA. As pacientes foram submetidas ao teste de função pulmonar e medidas de gases sanguíneos arteriais nos períodos pré-operatório e pós-operatório (três a seis meses). Os dados obtidos foram analisados por meio do teste de Wilcoxon e o nível de significância estatística foi p< 0,05. RESULTADOS: Nos dados obtidos por intermédio dos testes de função pulmonar, a capacidade pulmonar total e o volume residual foram maiores no pós-operatório (p < 0,05). Quanto aos dados de gases arteriais, não houve variações estatisticamente significantes. CONCLUSÃO: O aumento da capacidade pulmonar total e volume residual podem sugerir uma melhor função pulmonar após mastoplastia redutora em gigantomastia, apesar de não alterarem os gases arteriais das pacientes saudáveis
