Biliary lithotripsy: early observations in 106 patients. Work in progress.

One hundred six patients underwent extracorporeal shock wave lithotripsy for cholelithiasis. Of these, 28 patients underwent cholangiographically guided lithotripsy for bile duct stones to assist nonoperative stone removal by endoscopic or radiologic intervention. Fragmentation occurred in 20 of 28 cases (71%) with an average of two lithotripsy sessions. Hemobilia was observed in four patients (14%) for a 24-hour period. Seventy-eight of the 106 were outpatients with symptomatic cholecystolithiasis with one to five calculi who underwent cholecystographic or ultrasound-(US) guided shock wave lithotripsy as definitive therapy. US examination showed stone fragmentation in 86% of cases. With an average of 1.6 treatment sessions and 4,750 shocks, fragments were 4 mm or smaller in 46% of patients. Nine percent of patients had no fragments after an average of 10 weeks, but long-term follow-up is not yet available. Two patients developed acute pancreatitis attributable to fragment passage and one patient acute cholecystitis, likely due to cystic duct obstruction by a fragment.

Biliary extracorporeal shockwave lithotripsy.

Biliary extracorporeal lithotripsy has been considered one of the alternatives to surgery for the treatment of gallstones in the bile ducts and in the gallbladder. Although this technique can fragment almost all gallstones, the clinical effectiveness of this new treatment modality must be measured by successful elimination of all fragments. Some physical principles, stone targeting, patient protocol, complications, and clinical results are presented.

An echocardiographic study of cardiac changes in hypothyroidism and the response to treatment.

INTRODUCTION: Thyroid Hormones exert a direct cellular effect on almost all the tissues of the body including heart. Limited studies are available in the country to assess the various CVS parameters in hypothyroid patients and none have defined the impact of treatment on these parameters. AIM AND OBJECTIVES: To do an echocardiographic study of the cardiac changes in hypothyroidism and response to treatment. METHODOLOGY: 20 overt hypothyroid patients were selected , 12 males and 8 females and subdivided into 4 groups : untreated patients-A (14) , patients on L-thyroxin >=4 months-B6 , control subjects matched by age and sex-C10 , patient after treatment-D6-a subset of group A. Total T3 T4 was measured by RIA and TSH by IRMA. Echocardiography was done according to the standard protocols. RESULTS: With replacement therapy hypothyroid patients showed a decrease in wall thickness, decrease or disappearance of pericardial effusion and improvement in cardiac output. However no change in systolic function or size of various chambers were noted. Decreased cardiac output seen in untreated patients was mainly due to decreased heart rate. DISCUSSION: Present study showed relatively increased thickness of IVS and LVPW in untreated patients with marked difference in older patients consistent with other studies. There is a striking correlation between severity of disease and pericardial effusion. Following thyroid hormone replacement it was reported to resolve within few months. CONCLUSION: All patients with unexplained PE should be screened for hypothyroidism. Echocardiography is useful in assessing the response to replacement therapy. With replacement therapy hypothyroid patients showed a decrease in wall thickness.
