Risk factors for cholecystectomy: analysis of 935 patients.

We evaluated 935 patients for risk factors of cholecystectomy. Factors assessed included reason for cholecystectomy, preoperative laboratory values, sex, age, weight, presence of associated disease, and pathologic findings. Evaluation revealed an overall significant complication rate of 10.50% and a mortality of 1.07%. Risk factors were age over 60 years, hypertension, atherosclerotic cardiovascular disease with prior heart failure, and acute cholecystitis. Incidental cholecystectomy was associated with an increased risk due to concomitant associated disease. Patients with obesity and uncomplicated diabetes had the same risk as the general population.

Ulcerative colitis in Karachi.

Experience of 189 patients with non-specific ulcerative colitis has been reviewed. The majority of patients was in the 21-30 year age group, and neither sex predominated. Seventy-two percent had mild to moderate disease. The disease was mainly confined to the left colon (60%) and 13% had total colitis.

Intra-aortic balloon counterpulsation support for elective coronary angioplasty in the setting of poor left ventricular function: a two center experience.

A two-center elective coronary angioplasty experience with intra-aortic balloon pump support for patients with severe left ventricular dysfunction is reported. To prevent hemodynamic collapse, an intra-aortic balloon pump was inserted percutaneously before coronary angioplasty in 97 patients with a left ventricular ejection fraction less than 35% (26% of whom had ejection fractions less than 25%). The cohort was predominantly male (71%) with a mean age of 64 +/- 9 years. Angioplasty was successfully performed in 83 (85.6%) patients and 80 (82.5%) of these successful patients were discharged from the hospital. Seven patients had unsuccessful angioplasty without a major cardiac event. Seven patients (7.2%) suffered a major cardiac event; 4 had emergent coronary bypass surgery with q-wave infarction, 2 had uneventful emergency coronary bypass surgery, and one patient died in the operating room after a failed angioplasty. Using logistic regression analysis, the presence of multivessel disease and a history of prior myocardial infarction were associated with more complications during angioplasty (p less than 0.05). Intra-aortic balloon pump placement did not interfere with the angioplasty procedure. Two patients had limb ischemia which resolved when the intra-aortic balloon pump was removed. Of the 80 successful patients discharged, 72 were followed for a mean of 22 months. At the latest follow-up, 52 had not suffered a myocardial infarction and were alive. Of the 20 late deaths, 16 were cardiac and 4 non-cardiac.(ABSTRACT TRUNCATED AT 250 WORDS)
