Effect of Preoperative Administration of Oral Arginine and Glutamine in Patients with Enterocutaneous Fistula Submitted to Definitive Surgery: a Prospective Randomized Trial.

BACKGROUND: The use of glutamine and arginine has shown several advantages in postoperative outcomes in patients after gastrointestinal surgery. We determined the effects of its use in patients with enterocutaneous fistula after operative treatment. PATIENTS AND METHODS: Forty patients with enterocutaneous fistula were randomly assigned to one of two groups. The control group received the standard medical care while the patients of the experimental group were supplemented with enteral administration of 4.5 g of arginine and 10 g of glutamine per day for 7 days prior to the surgery. The primary outcome variable was the recurrence of the fistula and the secondary outcomes were preoperative and postoperative serum concentrations of interleukin 6 and C-reactive protein and postoperative infectious complications. RESULTS: Twenty patients were assigned to each group. The fistula recurred in two patients (10%) of the experimental group and in nine patients (45%) of the control group (P < 0.001). We found a total of 13 infectious complications in six patients of the control group (all with fistula recurrence) and none in the experimental group. Mean preoperative serum concentrations of interleukin 6 and C-reactive protein were lower in patients from the experimental group. In addition, these levels were lower in patients who had recurrence if compared to patients that did not recur. CONCLUSION: Preoperative administration of oral arginine and glutamine could be valuable in the postoperative recovery of patients with enterocutaneous fistulas submitted to definitive surgery.

Neutrophil-to-lymphocyte ratio as a prognostic factor for pharyngocutaneous fistula after total laryngectomy.

SUMMARY: The role of systemic inflammatory response as a prognostic factor has been proposed in a variety of cancers. The purpose of this study was to investigate the prognostic value of the pretreatment neutrophil-to-lymphocyte ratio (NLR) in the incidence of pharyngocutaneous fistula (PCF) in patients who underwent total laryngectomy. We conducted a retrospective cohort analysis of 141 patients with squamous cell carcinoma of larynx who underwent total laryngectomy from 2009 to 2015. The incidence of PCF was 49.6%. A higher risk of 23% was observed among patients with NLR > 2.5 for the occurrence of PCF (p = 0.007). Patients with laryngeal squamous cell carcinoma who present elevated values in the ration > LR> (> 2.5) presented a higher risk of developing pharyngocutaneous fistula in the postoperative setting of total laryngectomy.

Extravasación de mitomicina tras instilación postoperatoria / Mitomycin extravasation after postoperative instillation

OBJETIVO: Presentar el manejo terapéutico de complicaciones graves relacionadas con la extravasación de mitomicina postoperatoria. MÉTODOS: Descripción de los casos clínicos, el manejo médico y quirúrgico, y los resultados anatomopatológicos de las piezas quirúrgicas. RESULTADOS: Presentamos dos casos de pacientes con fuga extravesical de mitomicina tras su instilación en el postoperatorio. No se evidenció perforación de vejiga durante la cirugía del tumor. En ambos casos fue necesaria la realización de cistectomía radical. CONCLUSIONES: El uso de mitomicina en el postoperatorio puede tener consecuencias no deseables. Deben conocerse los problemas que pueden derivar de su administración e individualizar cada caso antes de administrar este quimioterápico

OBJECTIVE: To present the therapeutic management of severe complications related to postoperative mitomycin extravasation. METHODS: Description of clinical cases, medical and surgical management and pathologic results of surgical specimens. RESULTS: We report two cases of patients with extravesical mitomycin leakage after postoperative instillation. No bladder perforation was evident during tumor surgery. In both cases radical cystectomy was required. CONCLUSIONS: Postoperative mitomycin instillation may have undesirable consequences. The possible problems derived from its administration must be known, and each case must be individualized before administering this chemotherapy

[Predictive biochemical indicators of a postlaryngectomy pharyngocutaneous fistula: a clinical study]. / Indicadores bioquímicos predictivos de fístula faringocutánea postlaringuectomía: un estudio clínico.

UNLABELLED: The aim of this clinical study was to determinate biochemical predictor indicators of postlaryngectomy pharyngocutaneous fistula. PATIENTS AND METHODS: We have studied 100 patients with T2- 4 a laryngeal and piryform sinus carcinoma who underwent a laryngectomy. All patients were ASA 2-3. We studied serum albumin, protein serum level, cholesterol and lymphocites in each patient. These variables underwent statistical analysis (p < 0.05). RESULTS: 19% of the patients developed a postlaryngectomy pharyngocutaneous fistula, with a long-stay of 25 days vs. 10 days of stay in patients without postlaryngectomy pharyngocutaneous fistula. 7 postlaryngectomy pharyngocutaneous fistula needed surgical repair. Low serum albumin (< 3.5 g/dL) and a low level of serum proteins (< 6.5 g/dL) were predictive indicators of postlaryngectomy pharyngocutaneous fistula (p < 0.05). CONCLUSIONS: Our results suggest that a low-level of serum proteins and albumin are predictive clinical parameters of postlaryngeal pharyngocutaneous fistula.
