RESUMO
BACKGROUND: Chylous ascites is the pathologic leakage of triglycerides-rich lymphatic fluid into the peritoneal cavity. Chylous ascites is a rare complication in abdominal surgery. This study aimed to find a relatively better method for nutrition support in the treatment of chylous ascites after abdominal surgery. METHODS: This study was a retrospective study. This study retrospectively reviewed patients who underwent abdominal surgery and developed chylous ascites, from the year 2010 to 2014, at the West China Hospital of Sichuan University and the Affiliated Hospital of Zunyi Medical College. Fifty-eight patients who developed chylous ascites after abdominal surgery were included in the study. The clinical effect of somatostatin was evaluated. The differences in the curative efficacy among a daily diet, a low-fat diet supplemented with medium-chain triglyceride (MCT), and total parenteral nutrition (TPN) were also analyzed in this study. RESULTS: Complete clinical success was reached earlier in patients treated with somatostatin (P<0.001). The tube removal time, the time to resumption of an oral diet, and the length of hospital stay after chylous leakage were significantly different between patients treated with and without somatostatin. The curative efficacies of the enteral nutrition (EN) + MCT plan and the TPN plan were quite similar, with no significant difference, however, were significantly different from the MCT regime, which was the worst. However, using the EN + MCT plan was more cost-effective (P=0.038). CONCLUSION: In treating chylous ascites, EN + MCT instead of TPN was the best nutrition support. Moreover, somatostatin or its analog octreotide should be used immediately. The treatment with somatostatin in combination with EN + MCT is recommended in the conservative treatment of postoperative chylous ascites.
RESUMO
OBJECTIVE: To determine the clinical value of C-reactive protein(CRP), fibrinogen (FIB), or serum amyloid A protein (SAA) combined with 64 multi-slice computed tomography (MSCT) for preoperative staging and operative strategy in colon cancer. METHODS: Patients with colon cancer were prospectively enrolled at the West China Hospital of Sichuan University from November 2007 to July 2009,and were equally randomized into 3 groups undergoing different preoperative evaluation: MSCT combined with CRP(CRP group), MSCT combined with FIB (FIB group), and MSCT combined with SAA (SAA group). The agreement between preoperative staging and postoperative pathologic staging and that between expected surgical procedure and procedure adopted were compared. RESULTS: Baseline characteristics among three groups were similar(P>0.05). In CRP group, the accuracies of preoperative staging T, N, M and TNM were 65.7%, 72.4%, 100% and 66.7%, respectively. In FIB group, the accuracies of preoperative staging T, N, M and TNM were 71.4%, 74.3%, 99.0% and 65.7%, respectively. In SAA group, the accuracies of preoperative staging T, N, M and TNM were 60.0%, 55.2%, 96.2%and 51.4%, respectively. The accuracies of N and TNM staging in CRP group and FIB group were significantly higher than those in SAA group(P<0.05). However, there were no significant differences between FIB and CRP group(P>0.05). There were no significant differences in accuracy of predicting surgical procedures among three groups(93.3%, 92.3% and 87.6%, P>0.05). CONCLUSION: Combined assessment of MSCT and CRP or FIB may improve the accuracy of preoperative staging and procedure prediction, and is superior to MSCT combined with SAA.
