Modified Benchekroun technique for continent ileal stoma.

The Guzman continent ileal stoma is constructed by a modification of the Benchekroun technique, which is based on the principle of the inkwell and collapse of the inner tube through retrograde filling of the valve. We used this procedure in 7 patients, all of whom are continent. During a followup of 6 months to 2 years no major complications developed. The stoma is easy to construct, has a low risk of evagination because the inner tube is stabilized with sutures and is easy to catheterize. It does not require staples, which reduces the chance of stone or fistula formation. The terminal ileum in continuity with the cecum or an isolated ileal segment can be used.

[Some problems concerning the selection of the most appropriate mortality model for the indirect estimation of infant mortality].

"This paper analyzes the problems that arise when infant mortality estimates are derived through the probabilities of dying obtained from the application of the Coale-Trussell technique to the proportion of children deceased according to age of mother derived from census or survey data. These problems arise because this operation requires the acceptance of a mortality model by age." The author outlines "some criteria for the selection of the model through the use of information from Vital Statistics and surveys. Finally, it is stated that an alternative for the study of infant mortality trends is the selection of an indicator less affected by the mortality structure by age...." The problems are illustrated using data from selected countries in Latin America. (summary in ENG)
