Early onset of organ failure is the best predictor of mortality in acute pancreatitis.

BACKGROUND: APACHE II is a multifactorial scoring system for predicting severity in acute pancreatitis (AP). Organ failure (OF) has been correlated with mortality in AP. OBJECTIVE: To evaluate the usefulness of APACHE II as an early predictor of severity in AP, its correlation with OF, and the relevance of an early establishment of OF during the course of AP. PATIENTS AND METHODS: From January 1999 to November 2001, 447 consecutive cases of AP were studied. APACHE II scores and Atlanta criteria were used for defining severity and OF. RESULTS: Twenty-five percent of patients had severe acute pancreatitis (SAP). APACHE II at 24 h after admission showed a sensitivity, specificity, and positive and negative predictive value of 52, 77, 46, and 84%, respectively, for predicting severity. Mortality for SAP was 20.5%. Seventy percent of patients who developed OF did so within the first 24 hours of admission, and their mortality was 52%. Mortality was statistically significant (p< 0.01) if OF was established within the first 24 hours after admission. CONCLUSIONS: APACHE II is not reliable for predicting outcome within the first 24 hours after admission and should therefore be used together with other methods. OF mostly develops within the first days after admission, if ever. The time of onset of OF is the most accurate and reliable method for predicting death risk in AP.

[Transcultural adaptation of the Liver Disease Quality of Life instrument (LDQOL 1.0) for its use in the Spanish population]. / Adaptación transcultural del cuestionario específico de calidad de vida para hepatopatías crónicas (LDQOL 1.0) para su uso en la población española.

Instruments of health-related quality of life (HRQOL) help us to interpret the results of treatments and health interventions. In Spain there is no HRQOL instrument specifically designed for use in patients with liver disease or to measure the effect of interventions such as liver transplantation. The Liver Disease Quality of Life (LDQOL 1.0) questionnaire is an American instrument developed for use in these patients. The aim of this study was to produce an appropriate version of this questionnaire for use in Spain. Cultural adaptation was performed in 3 phases: a) modification for use in Spain of a Hispanic version of this questionnaire supplied by the original authors; b) back-translation to English of a new version of the questionnaire and comparison with the original version in English, and c) a pilot test in a small sample of patients. In the first phase consisting of revision of the Hispanic version, the changes were mainly linguistic due to cultural and idiomatic differences. The validated Spanish version of the SF-36 was directly incorporated and items that could be of interest to local investigators were added. Few changes were made in the second phase of the process: changes involved an item on the appearance of feces and another item on taking naps. In the final phase, various changes suggested by the patients were introduced. Before applying the new version of the LDQOL 1.0 in clinical studies in Spain, its psychometric properties (its reliability, validity and sensitivity to change) must be verified in a subsequent validation study.

[Results of cephalic pancreaticoduodenectomy in patients with chronic pancreatitis]. / Resultados de la duodenopancreatectomía cefálica en los pacientes con pancreatitis crónica.

OBJECTIVE: To analyse the results obtained after cephalic pancreatoduodenectomy in patients with severe chronic pancreatitis. DESIGN: Retrospective study of indications and results of the intervention.Patients. The inclusion criteria were severe anatomic alteration of the head of the pancreas associated with refractory pain. Pancreatoduodenectomy was performed in 19 patients. RESULTS: Four patients had postoperative morbidity, and the mean hospital stay was 15 days. One patient died in the postoperative period. The pain evolution after surgery was: total control in 72% and satisfactory control in the remaining patients. During follow-up, de novo diabetes was detected in two patients, difficulty in maintaining weight in one patient, and de novo steatorrhea in four patients. CONCLUSIONS: Cephalic pancreatoduodenectomy is a good therapeutic alternative for the treatment of patients with chronic pancreatitis, refractory pain, and severe involvement of the pancreas head. Pain control is excellent and sequelae, such as diabetes or steatorrhea, are easily amenable to medical treatment.

Mortalidad en el trasplante hepático: causas y período de máxima incidencia / Mortality in liver transplantation. Causes and period of maximum incidence

Objetivos. Describir y cuantificar las causas de muerte de nuestros pacientes e identificar su incidencia en los diversos períodos postrasplante. Pacientes y métodos. Durante el período de estudio, se realizaron 441 trasplantes hepáticos en 381 pacientes. Definimos como causa predisponente de fallecimiento aquella que pone al paciente en situación de riesgo de muerte, y causa inmediata la que precipita el fallecimiento. Definimos 3 períodos: mortalidad postoperatoria, temprana y tardía. Resultados. La mortalidad fue de 112 pacientes (29 por ciento). Los pacientes que fallecieron en período de mortalidad postoperatoria, temprana y tardía fueron 32 (30 por ciento), 13 (12 por ciento) y 65 (58 por ciento), respectivamente. Los tumores de novo (15 por ciento) y la recidiva viral (14 por ciento) fueron las causas predisponentes globales más frecuentes. Las infecciones (24 por ciento) y las complicaciones médicas (12 por ciento) fueron las causas inmediatas principales. En el período postoperatorio y temprano las causas más frecuentes fueron las complicaciones médicas y el rechazo ductopénico (4 por ciento), respectivamente; en cambio, en el período de mortalidad tardía lo fueron los tumores de novo (13 por ciento) y la recurrencia de hepatopatía por virus de la hepatitis C (13 por ciento). Conclusiones. La diferenciación entre causa predisponente e inmediata define con precisión la frecuencia de cada una de ellas. Los tumores de novo y la recurrencia de hepatopatía por virus de la hepatitis C son las causas más frecuentes de muerte global y tardía (AU)

A randomized trial on the effect of isotonic amino acid infusion on postoperative complications and short life plasma protein concentrations.

In a randomized clinical study 30 patients with high risk surgical procedures were distributed to receive either standard fluid-therapy (n = 14) or an isotonic amino acid solution (n = 16) during five days. The patients were evaluated pre- and postoperatively using: anthropometric parameters: body weight, biceps and triceps skinfold thickness, and mid arm circumference; biochemical parameters: albumin, prealbumin, transferrin, retinol-binding protein, total iron-binding capacity, and cholesterol; and delayed cutaneous hypersensitivity. Clinical outcome and complications were also recorded. Positive ketonuria was obtained soon in the treatment group after 24 h. Mean daily nitrogen balance was better in the protein sparing group (-3.8 g vs -9.3 g) p less than 0.02. No differences were observed between both groups in the postoperative plasma protein levels. There were no significant differences in delayed cutaneous reactivity nor anthropometric parameters between both groups; and mortality and morbidity were similar. The present study lends little support for substituting the routine D5W and saline postoperative fluid regime. No clinical advantage of amino acids over standard fluids could be appreciated indicating that the much less expensive conventional solutions should not be replaced by amino acids, at least in routine postoperative cases.

Does peripheral hypocaloric parenteral nutrition benefit the postoperative patient? Results of a multicentric randomized trial.

To study the potential benefits of hypocaloric peripheral parenteral nutrition (HPPN) in medium to high risk surgical patients we compared this regimen with standard fluid therapy during the postoperative period. Seventy patients were randomised to receive HPPN, consisting of 1 g of amino acids and 2 g of polyols (sorbitol and xylitol) per Kg per day (n = 41), or 1500 ml of 5% glucose and 1500 ml of saline (n = 29). There were no differences in length of hospital stay, postoperative complications or weight loss between the two groups. Concentrations of short and long half-life plasma proteins were similar in both groups. Nitrogen balance was negative and the nitrogen retention was low (60%) in the HPPN group. We conclude that there are no discernible clinical advantages in giving HPPN postoperatively to patients undergoing medium or major severity elective surgery.

Oral is superior to systemic antibiotic prophylaxis in operations upon the colon and rectum.

The prophylactic effect of a short preoperative loading dose of oral neomycin and erythromycin upon infectious complications following elective operations upon the colon and rectum was compared with the prophylactic effect of systemic administration of metronidazole and gentamicin preoperatively and postoperatively. In this randomized prospective clinical study, 45 patients received neomycin-erythromycin while 48 received metronidazole-gentamicin; all patients were prepared mechanically using whole gut irrigation with a mannitol solution. Both groups were comparable in sex, age, clinical diagnosis and type of operation performed. In the neomycin-erythromycin group, 41 of 45 patients had an uncomplicated postoperative course versus 35 of 48 patients in the other group (p less than 0.001) and fewer wound infections (p less than 0.05). We conclude that the better results observed with the neomycin-erythromycin combination is probably an addition of two effects--the decrease in colon flora and the adequate serum levels of antibiotics during the operation.

[Primary peritonitis. Study of four cases (author's transl)]. / Peritonitis primaria: a propósito de cuatro casos.

Four cases of primary peritonitis in the adult, with favourable evolution, are presented. This is a rare condition which still involves a not unappreaciable mortality rate. The treatment was surgical in three cases, in one case a paracentesis was performed and antibiotics were administered. The treatment included an exploratory laparotomy, smear with Gram stain and culture of the pus, washing of the peritoneal cavity with isotonic saline solution, appendectomy, closing of the abdominal cavity without drainage and parenteral antibiotic therapy. Exclusive medical treatment carries a greater risk of complications and should be reserved for those patients in very precarious general condition.
