Use of the pulsed dye laser and ultrasonic lithotriptor for removal of multiple intrahepatic gallstones.

Two established urologic modalities used for removal of kidney stones were applied in a complementary manner for percutaneous transhepatic removal of multiple intrahepatic gallstones. A pulsed dye laser was used through a flexible nephroscope to fragment a large impacted stone. A stone basket was used to remove stone fragments and a few small entrapped stones. Subsequently, an ultrasonic lithotriptor carried by a rigid nephroscope was tried and found to be a much more efficient means of removing the remaining small stones.

Manifestations of hypertrophic pulmonary osteoarthropathy in patients with carcinoma of the lung. Demonstration by 99mTc-pyrophosphate bone scans.

Two patients with carcinoma of the lung were studied with 99mTc-stannous pyrophosphate. Resolution of scintigraphic activity was observed postoperatively in one patient, while the second patient showed an asymmetric pattern of radionuclide uptake and radiographic changes as well as clinical findings of hypertrophic pulmonary osteoarthropathy.

Focal splenic defects.

Review of more than 2,000 liver-spleen scans revealed 18 cases of focal splenic defects. Three major categories are defined: lymphoma, infarctions, and metastatic tumor. Clinical presentation is important in determining the precise etiology, and a differential diagnosis is presented. It appears that: (a) reticulum cell carcinoma is as likely to cause defects as is Hodgkin's disease; (b) splenic infarction is related to pancreatic disease through the splenic vein; and (c) malignant melanoma is the most common secondary deposit as detected by scanning.
