Treatment of enterocutaneous fistulas by double cannula with an early oral diet in non-high output enterocutaneous fistula / 临床外科杂志

Objective To investigate the efficacy of double cannula with an early oral diet as nutritional support treatment on non-high output enterocutaneous fistulas. Methods Clinical data from patients with non-high output enterocutaneous fistula, who treated with double cannula with an early oral diet (n = 39) and double cannula with enteral nutrition therapy (n = 43), were retrospectively analyzed. The fistulas status and its closure time were recorded. In order to investigate the effect of oral diet on fistula, the inflammation index and nutritional status indicators before and after therapy were recorded. Results Totally 33 cases of the 39 patients with non-high output fistula were cured after therapy on the average (16.4土7.2) days. The distal non-high output fistula patients had better results(93.1％ closed, 15.8 days)than that of the proximal fistula patients(60.0％, 19.8 days). Laboratory inflammation index(TNF-alpha, IL-6, plasma endotoxin and C-reactive protein) were improved significantly (P＜ 0.05) after therapy. The nutrition status of these patients, such as body weight, hemoglobin, serum total protein, albumin, transferrin, and prealbumin increased at the end of fistula compared to that at the beginning of treatment (P＜ 0.05). Prealbumin and retinol binding protein were significantly higher than that in the control group (P＜0.05). Conclusion With double cannula treatment, early normal eating for enteral nutrition is safe and effective, especially in distal enterocutaneous fistulas. Normal oral diet can achieve the results of fistula closure, reduction of the inflammatory reaction, improvement of the nutrition status, avoiding the infliction of the operation and lowering the cost.

Development of Abdominal Vacuum Extractor Characterized by Portability and Constant Negative Pressure Which Applying to Battlefield / 中国医疗器械杂志

There are some problems such as difficulty of pressure control, inconvenience of use and carry, congested easily and dredged hardly in clinical application of vacuum extractor in common use. For solving the above problems, researchers have designed a new portable and pressure stabilized abdominal drainage system which was composed of integral double spherical aspirator and separated double cannula. The new apparatus has achieved good effects in drainage which is suitable for not only rescuing of abdominal trauma and war wound, but also abdominal surgery that manifested as sucking safe and effective, using easily and convenient, that was verified by testing.
