Endoscopic electrohemostasis of active upper gastrointestinal bleeding.

Emergency esophagogastroduodenoscopy for active upper gastrointestinal bleeding was performed in 160 patients. Endoscopic electrocautery for control of bleeding was considered in the last ninety patients and performed in seventy-one patients. All lesions except esophageal varices were candidates for electrohemostasis. The indications for endoscopic electrocautery were active hemorrhage and precise identification of the bleeding point. The preendoscopic blood loss ranged from 1,500 to 6,000 ml. All seventy-one patients had initial hemostasis and sixty-five (92 per cent) had permanent hemostasis after one treatment. Six patients rebled, and four of these had permanent hemostasis after a second endoscopic electrocauterization. Only two of seventy-one patients had emergency operations for bleeding. There were no complications. Endoscopic electrohemostasis is still an experimental technic which requires further laboratory study and testing before broad general clinical application. This clinical trial suggests that endoscopic electrocautery is an attractive method of controlling active upper gastrointestinal bleeding because it can be safe, effective, and rapid, and is available in most medical communities.

Endoscopic retrograde cholangiopancreatography in the diagnosis of jaundice.

Endoscopic retrograde cholangiopancreatography (ERCP) was successfully accomplished in 395 patients or 97 per cent of the patients in whom it was attempted. Of 157 patients with cholestatic type jaundice, satisfactory endoscopic retrograde cholangiography or cholangiopancreatography was accomplished in 145 (92 per cent), with only one complication. ERCP excluded extrahepatic biliary ductal obstruction and thus avoided unnecessary surgical exploration in forty-nine patients with cholestatic jaundice. ERCP established the diagnosis of obstructive jaundice in ninety-six patients and delineated the site of ductal obstruction and probable cause. ERCP revealed additional significant previously undiagnosed upper gastrointestinal pathologic changes in 25 per cent of jaundiced patients.

Peritoneoscopy: A valuable technic for surgeons.

1. Modern peritoneoscopy which uses advanced optics and instrumentation now available is a valuable technic that can and should be learned by surgeons. 2. Peritoneoscopy is a safe procedure with a high diagnostic yield and minimal discomfort and inconvenience to the patient. 3. Earlier and more frequent use of peritoneoscopy will enable the surgeon to give appropriate surgical treatment more promptly and avoid unnecessary exploratory celiotomy. 4. The value of this technic in seventy-five consecutive cases is reported. There was no mortality and negligible morbidity. The over-all diagnostic accuracy was 91 per cent. An accurate peritoneoscopic diagnosis avoided surgical exploration in forty-five patients, and in fifteen patients the peritoneoscopic diagnosis provided indications for prompt abdominal surgery.
