Drenaje transrectal de abscesoperianastomótico en resección anterior baja porcáncer de recto. Un método de rescate en casosseleccionados / Transrectal drainage of perianastomotic abscess after low anterior resection for rectal carcinoma. A rescue method in selected patients

Presentamos una pauta terapéutica de rescate en tres pacientes mediante drenaje transanastomótico del absceso retrorrectal, nutrición parenteral y antibioterapia (AU)

Adenoma velloso de apéndice. Actitud diagnóstica y terapéutica / Villous adenoma of the appendix. Diagnostic and therapeutic approach

El adenoma velloso de apéndice es una entidad patológica rara que adopta formas de presentación clínica que difieren de la de los adenomas vellosos en otras localizaciones del tubo digestivo. Pacientes y métodos: hemos revisado los casos de adenoma velloso apendicular que se han diagnosticado en nuestro hospital en un periodo de tiempo de cinco años. Se estudia la distribución por edades, sexo, las formas de presentación clínica, los métodos diagnósticos empleados, el tratamiento efectuado y el seguimiento realizado. Resultados: se han diagnosticado un total de seis casos de adenoma velloso apendicular siendo la forma de presentación clínica más habitual la apendicitis aguda. Los tratamientos aplicados fueron apendicectomía en 2 casos, hemicolectomía derecha en 2 pacientes, colectomía subtotal en un paciente y Hartmann más apendicectomía en otro caso. Conclusiones: consideramos que la apendicectomía será el tratamiento de elección siempre que no haya degeneración maligna del adenoma y que este no invada el borde de resección quirúrgica (AU)

Villous adenoma of the appendix. Diagnostic and therapeutic approach.

UNLABELLED: Appendix villous adenoma is a rare pathological entity that shows a particular form of clinical presentation that is different from villous adenomas in other places along the gastrointestinal tract. PATIENTS AND METHODS: We reviewed cases of appendix villous adenoma diagnosed in our hospital during the last five years; we studied age, distribution, sex, clinical presentation, diagnostic methods used, treatment and follow-up of patients. RESULTS: We diagnosed 6 cases of villous adenoma of the appendix, acute appendicitis being the most common form of clinical presentation. Treatment was appendectomy in two cases, right hemicolectomy in two patients, subtotal colectomy in one case, and Hartmann's technique with appendectomy in one more case. CONCLUSIONS: We consider appendectomy the treatment of choice when no malignant degeneration is present in the adenoma and invasion of surgical resection borders is absent.

Un caso de esparganosis humana en Argentina / A case of human sparganosis in Argentina

A male patient from Peru presented a nodule localized in the left costal region. All other clinical and laboratory data were normal. Upon biopsy, an helminth parasite emerged from the subcutaneous tissue, which presented a marked eosinophil infiltrate. The helminth was classified as a plerocercoid larva of Spirometra; the species was not determined. Since Spirometra are not common in Argentina, it is presumed that the patient was infested during his two year sojourn in the peruvian forest. Some epidemiological aspects are discussed. As far as we know, this is the first case of subcutaneous sparganosis and the second of sparganosis reported in Argentina.(Au)

Ear replantation.

The authors' tactical and technical contribution to this type of microsurgical replantation can be summarized in three main points: (1) direct sutures to the superficial temporal vessels, when these are undamaged, which simplifies the operation and makes it safer; (2) use of Kunlin's technique to make up for the great difference in diameter between the arterial vessels; and (3) deepithelialization of the posterior auricular skin to allow for creation of venous drainage channels during the first postoperative days and the enlargement of the area of contact with the recipient bed, which also helps to better immobilize the amputated part.
