Abstract

Within the spectrum of intra-abdominal infection, secondary peritonitis is the most common condition confronted by surgeons. The scores available to assess severity of illness are unable to reconcile the needs of the individual surgeon and the demands of clinical researchers studying these patients. Considering their aim, the medical scenarios and conditions for which they were devised, the manner in which the variables of interest were selected, and their applicability, this chapter discusses eleven of the scores most frequently cited in the MEDLINE data base. Considering the diversity of conditions, the moment and place of the evaluation, and the limitations of each score, the chapter makes suggestions for their use and invites further discussion in this changing field.

Keywords: intra-abdominal infection; secondary peritonitis; severity of illness index

Bracho-Riquelme RL, Melero-Vela A, Torres-Ramírez A. Mannheim Peritonitis Index Validation Study at the Hospital General de Durango (México). Cir Cir 2002; 70 (4):217-225.

A study to confirm the predicative value of the Mannheim peritonitis index (MPI) among patients at the Hospital General de Durango was undertaken to evaluate the severity of peritonitis and to make a prognosis of survival-mortality pondering each risk factor. The simplicity of MPI makes it ideal for hospitals with serious shortages such as those in Mexico). From March 1 to November 30, 1999, 176 cases were studied. Patients were divided into groups according to the following categories (MPI points): a) < 21, 21 – 29 and >29, and b) <26 and >26. A life table was constructed to compare patient survival with peritonitis severity. Odds ratios that analyzed presence or absence of each adverse factor and outcome were calculated. Survival curves of the three subgroups (<21, 21 – 29, and >29) had differences that were statistically significant (p < 0.0001). Patients with >26 points had a mortality rate of 40%, whereas patients with <26 MPI points did not reach a 3% mortality rate. All MPI adverse factors, except of colonic origin, behaved as expected, and the following were especially useful: organic failure; time elapsed >24 h; malignancy; age >50 years, and generalized peritonitis.

Key words: Peritonitis, Scoring systems, Outcome predictors.

Para confirmar el valor predictivo del índice de peritonitis de Mannheim (MPI) en la población de afluencia al Hospital General de Durango, SSA se realizó un estudio evaluando la severidad de la peritonitis y buscando ponderar cada factor de riesgo. La sencillez del MPI lo hace ideal para hospitales con carencias, comunes en nuestro país. Se estudiaron 176 casos del 1º de marzo al 30 de noviembre de 1999, dividiendo a los pacientes en las siguientes categorías (puntuación MPI): a) < 21 pts., 21 – 29 pts., > 29 pts.; b) < 26, > 26. Se elaboró una tabla de supervivencia para comparar la sobrevida por grupo y se calculó la razón de momios analizando la presencia de cada factor de riesgo y la supervivencia. La diferencia en sobrevida entre los tres grupos (< 21, 21 – 29 y > 29) fue estadísticamente significativa (p < 0.0001). Los pacientes con > de 26 pts. MPI tuvieron una mortalidad del 40%, mientras que aquéllos con < no llegaron al 3% de mortalidad. Todos los factores de riesgo, excepto el origen colónico, se comportaron de manera esperada y fueron especialmente orientadores: la presencia de falla orgánica, tiempo transcurrido > 24 h., la presencia de malignidad, edad > 50 años y la presencia de peritonitis generalizada.
