Use of oil preparations for hemostasis in gastroduodenal hemorrhage

The authors report on using oil preparations in endoscopic surgery for arrest of bleedings from vessels of the stomach and duodenum. Persistent hemostasis was obtained in 60 out of 64 patients.     

Use of the gastroduodenal artery in right renal artery revascularization

Of 15 patients having revascularization of the right renal artery with the use of the hepatic circulation from May 1984 through March 1987 at the Massachusetts General Hospital, eight patients had this accomplished with end-to-end anastomosis of the gastroduodenal artery and right renal artery. Operative indications were acute azotemic renal failure (three patients), poorly controlled renovascular hypertension (four patients), and staged repair of bilateral renal artery disease (one patient). All revascularizations were successful in restoring renal function or rendering hypertension manageable and were assessed by means of renal flow scans, celiac angiography, or return of function in those patients with a solitary, functioning kidney. All patients survived the operation with one late death caused by myocardial infarction after abdominal aortic aneurysm repair. The gastroduodenal artery may be used as the source for arterial inflow in revascularization of the right renal artery by end-to-end anastomosis in approximately 50% of instances, conferring the advantage of the use of only one anastomosis and obviating the long-term possibility of vein graft failure.     

Duodenoscopy and endoscopic pancreatography in patients with positive morphine prostigmine tests

Twenty-three patients with abdominal pain and positive morphine prostigmine tests underwent duodenoscopy and endoscopic retrograde cholangiopancreatography (ERCP). Sixteen demonstrated marked or moderate ampullary stenosis. The pancreatic duct was dilated in three and stenotic in four. Ampullary stenosis was confirmed in all patients who subsequently underwent sphincteroplasty. Only six patients had pancreatitis demonstrated by appropriate laboratory studies or at surgery. Relief of pain after sphincteroplasty was complete in ten patients during follow-up.     

Use of an artificial carrier of oxygen on the base of modified hemoglobin in patients with gastroduodenal hemorrhage

Infusions of Helenpole used in 23 patients allowed for a short time to stabilize hemodynamics and to considerably improve the gas-transporting function of blood. The best curative effect in patients with hemorrhagic shock was obtained by means of intravenous jet infusions of the medicine, after stabilization of the hemodynamic indices with the help of an intravenous dropper (80-90 drops/min). The dose of the 1% solution of the medicine was 25-30 ml/kg of the patient's body weight.     

Immunologic reactivity in patients with gastroduodenal ulcers

Immune system factors were studied in 158 patients with ulcer disease of the stomach and duodenum before and after different operative procedures. More pronounced alterations of immune reactivity as compared with the parameters in patients with noncomplicated ulcer disease were found which manifested themselves in decreased indices of cell immunity, activation of processes of autoallergization, inhibition of nonspecific factors of defense.     

胃十二指肠手术史患者的腹腔镜胆囊切除术

目的 :探讨有胃十二指肠手术史患者行腹腔镜胆囊切除术的可行性及疗效。方法 :回顾分析有胃十二指肠手术史 86例的腹腔镜胆囊切除术手术过程。结果 :气腹建立困难 8例 ,腹腔严重粘连无法分离 7例 ,胆囊周围粘连包括Calot三角粘连分离困难 4例均行中转开腹手术。第 1孔穿刺损伤肠管 2例 ,分离粘连时损伤肠管 1例 ,均在腹腔镜下修补。结论 :胃十二指肠手术后腹腔内严重粘连是气腹建立困难或腹腔粘连分离困难而中转开腹的主要原因。第 1孔穿刺肠管损伤和腹腔粘连分离肠管损伤发生率较高。严格掌握手术适应证 ,腹腔镜操作技术娴熟是手术成功的关键
