Endoscopic laser therapy for neoplastic lesions of the colorectum.

Surgical resection is the therapy of choice for most colorectal neoplasms. Endoscopic laser therapy (ELT) is a recently developed alternative for treatment of colorectal neoplasms and is applicable in a variety of clinical circumstances in which nonoperative treatment is preferable. The experience with ELT using the Nd:YAG (neodynium:yttrium-aluminum-garnet) laser in 42 patients was analyzed.

Cytomegalovirus colitis presenting as hematochezia and requiring resection.

Cytomegalovirus infection is one of the most prevalent viral infections affecting recipients of cardiac allografts. Of the various severe systemic manifestations, those in the gastrointestinal tract have a unique way of presenting, specifically in the colon where a process related to cytomegalovirus infection that involves all layers, with dilatation as a prominent clinical feature, has been suggested. We report herein a case of patient with a heart allograft who had severe episodes of rejection that responded to boosting doses of steroids.

Choledochoduodenostomy. Analysis of 71 cases followed for 5 to 15 years.

To investigate the long-term effectiveness of choledochoduodenostomy (CDD), the experience with 71 patients followed for 5 or more years after CDD was analyzed retrospectively. From 1968 to 1984, 134 patients underwent CDD. Eight patients (6%) died in the immediate postoperative period, 55 left the hospital, 8 of them were lost to follow-up, and 47 were followed but died before 5 years elapsed after CDD.
