RESUMEN
Giant diverticula of the small intestine and colon are rare. Four cases treated at our institution in the last year are reported and compared to published cases; specific features and those which differentiate them from abdominal pseudocysts are described. They most commonly present a clinical tableau similar to commonplace diverticular disease. Awareness of this unusual condition and a good CT study are the keys to diagnosis. Giant diverticula may be acquired or congenital. The acquired type is simply a more spectacular version of commonplace diverticulosis while the congenital type, having a muscular wall and myenteric plexus, is more akin to intestinal duplications. Treatment is surgical and, in the case of sigmoid giant diverticula, usually requires a colon resection similar to that required for sigmoid diverticulitis.

A 58-year-old man had a persistent perineal sinus following an abdominoperineal resection. An excision of the sinus was performed. Histology revealed that the sinus tract was bordered by a granulation tissue exhibiting numerous vacuolated cells containing polyvinylpyrrolidone. The origin of polyvinylpyrrolidone was related to lengthy irrigation of the fistula with Betadine.

Presacral tumors have miscellaneous histologic structures: some of them, among the most uncommon, are malignant tumors and lay it down that the extirpation must be the most complete as possible. Often they are uncovered when they compress adjoining organs (rectum, bladder, ureters, sacral plexus) and they appear voluminous, encrusted in the pelvic excavation, taking a rich vascularisation from surroundings. This adhesion involves a laborious extirpation, often hemorraegic, but needful even in benignant tumors. On this understanding and with the help of a good approach, pelvic organs can be decompressed with restricted risks of recurrence.
