Hirschsprung's disease with skip area (segmental aganglionosis).

Hirschsprung's disease is characterized by a single aganglionic segment of colon extending distally to the anal margin. Well documented reports of segmental aganglionosis have been rare. We report a case of segmental aganglionosis in which there were two distinct aganglionic segments resected. The entire transverse colon between the two aganglionic segments was normally ganglionated, preserved, and utilized and functions in a normal fashion.

Expanded polytetrafluoroethylene as dialysis access grafts: serial study of histology and fibrinolytic activity.

Expanded polytetrafluoroethylene (Gore-Tex) grafts were evaluated as hemodialysis access shunts. A serial study of cellular ingrowth and endothelialization was performed. The development of fibrinolytic activator was sequentially monitored and shown to be consistently higher in the Gore-Tex grafts than in either knitted or woven Dacron prostheses. Functional assessment by repeated needle puncture demonstrated that PTFE grafts were durable, had uniform patency (6 mm ID size) and showed no evidence of degeneration during the time limit of this study. Although these are favorable characteristics, further long-term evaluation of PTFE grafts is necessary before its role as a vascular prosthesis applicable to clinical practice, can be established.

Comparison of dietary therapy and portacaval shunt in the management of a patient with type Ib glycogen storage disease.

A patient with glycogen storage disease type IB (GSD-Ib) is described. Beginning at age 34 months, the patient was managed with dietary measures, including nocturnal intragastric feedings. Therapy caused substantial biochemical and clinical improvement while the patient remained hospitalized; chronic noncompliance at home, however, resulted in profound growth failure and biochemical abnormalities. Due to a previous case report describing clinical, biochemical, and hematological improvement following a portacaval shunt in a similar patient, portacaval shunt was performed in our patient at age 13 years. During the 12 months following surgery, there was no improvement of our patient's growth or of biochemical or hematological abnormalities. Due to the lack of improvement following surgery, 24-hour constant infusion intragastric feedings were instituted and have been associated with substantial benefit.
