Laparoscopic cholecystectomy in patients with cardiac dysfunction.

Laparoscopic cholecystectomy remains the standard treatment for cholelithiasis. Ever increasing number of patients with myriad of medical illness is being treated by this technique. However, significant concern prevails among the surgical community regarding its safety in patients with cardiac co-morbidity. Patients with significant cardiac dysfunction and multiple co-morbidities were prospectively evaluated. Patients were assessed by cardiologists and anesthesiologists and laparoscopic cholecystectomy was performed. Patient demographics, details of peri-operative management and post-operative complications were studied. Between March 2005 and January 2009, 28 patients (M:F = 21:7) with mean age of 60 years (range 26-78) and having significant cardiac dysfunction had undergone laparoscopic cholecystectomy. Of these, 24 patients were in NYHA class-II, while 4 belonged to class-III. Left ventricular ejection fraction, as recorded by transthoracic echocardiography, was 20-30% in 13 (46%) patients and 30-40% in the rest 15 (54%). In addition, 13 (46%) patients had regional wall motion abnormalities, 11 (39%) patients had cardiomyopathy, 2 (7%) patients had valvular heart disease while 12 (43%) patients had prior cardiac interventions. Following laparoscopic cholecystectomy, hypertension (3), tachyarrhythmia (4) and bradycardia (1) were the commonest events encountered. One patient required laparotomy to deal with peritonitis in the immediate postoperative period and succumbed to myocardial infarction, but all other patients made an uneventful recovery. With appropriate cardiological support, laparoscopic cholecystectomy may be safely performed in patients with significant cardiac dysfunction.
