These results indicate that this increasingly common disease frequently leads to a fatal outcome in patients requiring surgery and implies that earlier surgical consultation may be necessary to improve survival in patients with fulminating C. difficile colitis unresponsive to antibiotic therapy.

This study examined respiratory function and metabolic and subjective responses in patients undergoing laparoscopic (n = 10) and open (n = 11) cholecystectomy for chronic cholecystitis and biliary colic. Patient groups were matched for age, sex, weight and height. The duration of operation was similar in both groups. Respiratory function tests (vital capacity, forced expiratory volume in 1 s, peak flow and arterial blood gases), urinary cortisol, vanillylmandelic acid, metanephrines and nitrogen loss, serum complement component C3 and C-reactive protein (CRP), full blood count, erythrocyte sedimentation rate (ESR) and subjective responses as assessed on a pain analogue scale and by analgesic usage were determined for up to 48 h after surgery. Deterioration in perioperative respiratory function was significantly less for laparoscopic surgery. Arterial blood gas determinations indicated a greater perioperative decrease in arterial pH, with carbon dioxide retention in patients undergoing open cholecystectomy (P < 0.02), reflecting poorer respiratory performance. Hormonal profile changes demonstrated an increase in urinary vanillylmandelic acid in the laparoscopic cholecystectomy group (P < 0.04); no differences were detected in urinary cortisol, metanephrine or nitrogen excretion. Acute-phase responses were greatest in patients undergoing open cholecystectomy as determined by ESR and CRP level (P < 0.02 and P < 0.003, respectively). Pain and analgesic usage were significantly decreased in the laparoscopic cholecystectomy group (P < 0.0009) and P < 0.0001), which led to a decreased hospital stay after operation in these patients (P < 0.0001). These data indicate improved respiratory and subjective responses and diminished acute-phase responses associated with laparoscopic surgery. Catabolic hormone release may, however, be increased.

Background: Laparoscopic cholecystectomy is commonly performed, and several factors increase the

Readmissions and complications following cholecystectomy are common and associated with patient and disease characteristics.
