A patient with metastatic gastric carcinoma and malignant ascites developed sudden-onset dyspnea secondary to a new large left pleural effusion. A radionuclide lung scan performed for suspected pulmonary embolism was indeterminate. Scintigraphy performed following intraperitoneal administration of Tc-99m sulfur colloid subsequently demonstrated rapid accumulation of activity in the left pleural space, indicating the presence of a pleuroperitoneal communication. In a patient with known or suspected ascites, a new pleural effusion, and an indeterminate lung scan, peritoneal scintigraphy may identify the origin of the effusion and obviate the need for further invasive evaluation for possible pulmonary embolism.

The intraperitoneal instillation of dialysate increases intra-abdominal pressure and consequently predisposes to subcutaneous infiltration, leaks, and herniations through defects in the abdominal wall. In this setting, the incidence of abdominal hernias ranges between 9% and 24%. Life-threatening complications (incarceration/strangulation) occur in up to 13.2% of hernias. Therefore, the authors evaluated the efficacy of the Tc-99m sulfur colloid (SC) intraperitoneal scan in the detection of abdominal leaks and hernias in 11 continuous ambulatory peritoneal dialysis (CAPD) patients over a 2-year period at the Hospital of the University of Pennsylvania. Eleven patients (7M, 4F) ranging in age from 24 to 72 (mean = 50.8), on CAPD, were evaluated for clinically suspected abdominal hernias or dialysate leaks with intraperitoneally administered Tc-99m SC. After the injection of 3-5 mCi of Tc-99m into a standard 2 liter dialysate bag, multiple sequential anterior images of the abdomen were obtained in the supine position over the course of one hour. Delayed images were obtained after ambulation and post-drainage two or more hours postinjection in multiple projections and positions in order to demonstrate any abnormal focal accumulations of fluid to the best advantage. Any detected abnormalities were marked and correlated with the physical examination and the patient's symptoms. Two patients had normal scans. Of the nine abnormal scans, five hernias were identified in four patients and six leaks were detected in the other five patients.(ABSTRACT TRUNCATED AT 250 WORDS)

A 55-year-old man with an 11-year history of intermittent right pleural effusions had continued fevers and a large right transudative pleural effusion. Minimal ascites was noted by ultrasound examination. A communication between the thorax and intraperitoneal cavity was established by radionuclide examination of the chest and abdomen. Tc-99m sulfur colloid was injected into the peritoneal cavity, and imaging at 1 and 4.5 hours confirmed passage from the peritoneal to the pleural cavity. Repeated attempts to sclerose the pleural cavity failed to decrease the transudative accumulations. The patient was subsequently treated with the placement of a LeVeen shunt.

Eighteen patients with complications secondary to continuous ambulatory peritoneal dialysis underwent peritoneal scintigraphy utilizing Technetium-99m sulfur colloid. Patients were divided into three groups. Group 1 patients (11) had dialysate leaks leading to abdominal-wall edema, genital edema, or exit-site drainage. Scintigrams were abnormal in nine patients in this group and frequently provided localizing information that aided in the management of leaks. Group 2 patients (five) had recurrent peritonitis. Two of these patients had abnormal scintigrams. In one instance, scintigraphy detected multiple abdominal-wall hernias that may have been responsible for recurrent peritonitis, which resolved following corrective surgery. Group 3 patients (two) had inadequate ultrafiltration but no clinical evidence of a dialysate leak. Scintigrams were negative in this group, eliminating consideration of an underlying structural defect in the peritoneum. Scintigraphic imaging is possible for several hours following instillation of labeled dialysate. This capability is important, since scintigrams that were initially negative frequently became positive after several hours of ambulation. Postdrainage images were also helpful in confirming extraperitoneal leakage. This study demonstrates that peritoneal scintigraphy is a useful diagnostic tool in the management of complications of continuous ambulatory peritoneal dialysis.

A 54-yr-old female with known liver cirrhosis presented with a right transudative pleural effusion and ascites. To find the source of pleural fluid, [99mTc]sulfur colloid was injected intraperitoneally and a serial imaging study revealed its passage to the right pleural space on 2-hr and 24-hr images. Mechanisms proposed in the formation of pleural effusion in liver cirrhosis are (a) lymphatic drainage and (b) diaphragmatic defect. Radioisotope migration speed may be a clue for differentiating these two mechanisms, being more rapid in the presence of a diaphragmatic defect.

Ten minutes after an intraperitoneal infusion of Tc-99m sulfur colloid, a gamma camera was used to obtain anterior abdominal views. This visualized a peritoneoscrotal communication in an 80-yr-old patient. He had developed extensive edema of the genitals and lower limbs after about 6 wk of continuous ambulatory peritoneal dialysis. At operation the communication was confirmed and closed. A repeat test verified the success of operation.
