Intraocular lens implantation in severely mentally and physically handicapped patients.

Posterior chamber intraocular lenses (PC-IOL) were implanted in 42 eyes of 24 severely mentally and physically handicapped patients, and the results were analyzed in comparison with implants in conventional patients. The patient eyes included in this study were 21 eyes of 13 severely mentally retarded patients, 19 eyes of 10 Down's syndrome patients, and 2 eyes of a patient suffering from mitochondrial encephalomyopathy. Surgeries had been performed under general anesthesia and resulted in significant improvement in vision and quality of life. Severe postoperative complications occurred in one of the eyes of two patients. However, the fellow eye of these patients, which also received a PC-IOL implantation, showed an uneventful postoperative course. The present study indicated that cataract surgery with PC-IOL in patients with severe mental and physical handicaps should be considered as an appropriate and promising application in spite of the various technical difficulties in the pre- and postoperative management of these patients. It is stressed that proper calibration of IOL power immediately before surgery under general anesthesia and small incision techniques are essential for a successful operation in patients with severe mental and physical handicaps.

Metallic expanding biliary stents in malignant obstruction. Cases with stent in stent.

We reviewed a total of 13 stent (Gianturco-Rosch biliary Z-stent) placements in 11 patients with biliary obstruction due to malignancy and report the cases treated with the stent-in-stent technique for treatment of stent occlusion due to tumor ingrowth. Causes of biliary obstruction included cholangiocarcinoma (four cases), hepatic hilar metastasis of gastrointestinal carcinoma (five cases), and pancreatic carcinoma (two cases). After transient percutaneous transhepatic biliary drainage (PTBD), the stents were successfully inserted by transhepatic route in all patients without any serious complication that needed further surgical intervention. Almost all patients were freed from the external PTBD tube about a week after stent placement and discharged from the hospital with improvement in quality of life as well as normal serum bilirubin levels. The technical advantages of stent placement include ease of insertion and the ability to drain both right and left biliary systems from a single transhepatic route by arranging the stents in a variety of configurations. Furthermore, it provides a second chance of stent placement when the previous stent has been occluded by tumor ingrowth.
