Laparoscopic cardiomyotomy for achalasia: long-term outcomes.

BACKGROUND: Although the laparoscopic approach to oesophageal myotomy for achalasia is associated with reduced early postoperative morbidity compared with the open approach, most published reports describe relatively short-term follow up. For this reason, in a prospective cohort study, we determined the longer-term outcome for patients with uncomplicated achalasia who underwent a laparoscopic myotomy. In addition, we sought to identify preoperative factors predicting a good postoperative outcome. METHODS: The outcome for 167 patients who underwent a laparoscopic cardiomyotomy and anterior partial fundoplication at one of two teaching hospitals was determined. All patients underwent preoperative assessment with a contrast swallow radiology, gastroscopy and oesophageal manometry. Patients also underwent objective symptom evaluation before and after surgery using various outcome scales to determine dysphagia, reflux symptoms, side-effects and overall satisfaction with the clinical outcomes. Patients were followed prospectively at yearly time points and data were managed on a computerized database. Postoperative objective investigations were undertaken if clinically indicated. RESULTS: Median operating time was 78 min (range, 30-210 min). Most patients left the hospital within 72 h of surgery. Surgery was associated with a 5% complication rate and a 4% rate of conversion to open surgery. Five per cent of patients required a subsequent intervention during follow up. Over longer-term follow up (5 years or longer), 77% of patients had either no or minimal symptoms. At 1, 3 and 5 years, 96, 93 and 97% of patients indicated that they thought that they had made the correct decision to undergo surgery, although men consistently fared worse on their reported dysphagia outcome across a range of measures. CONCLUSION: Laparoscopic myotomy with anterior partial fundoplication achieves a good outcome for patients undergoing treatment of achalasia. Male patients do not perceive their outcome to be optimal in comparison with females but in the long term, they do not regret proceeding.

Improving surveillance for Barrett's oesophagus.

PROBLEM: A retrospective audit of surveillance for Barrett's oesophagus 1996-2001 identified the need to improve adherence to guidelines for the endoscopic surveillance of patients with Barrett's oesophagus. DESIGN: Prospective audit of the effect of disseminating guidelines in 2002. Prospective audit of the effect of introducing local guidelines and Barrett's oesophagus surveillance officers, 2003-2005. SETTING: Two general hospitals in Australia, 2002-5. All adult patients diagnosed with Barrett's oesophagus were included. KEY MEASURES FOR IMPROVEMENT: Proportions of patients in a Barrett's oesophagus surveillance programme who had appropriate time intervals between follow-up endoscopies and who had appropriate numbers of biopsies collected at endoscopy. STRATEGIES FOR CHANGE: Local guidelines were laid down. Surveillance coordinators for Barrett's oesophagus were introduced to manage the process according to a clinical protocol designed for each patient. EFFECTS OF CHANGE: Disseminating guidelines had little effect on practice. Six months after surveillance coordinators were introduced, adherence to the planned surveillance interval increased from 17% to 92% and the number of endoscopies at which sufficient biopsies were collected increased from 45% to 83%. These changes have been maintained. LESSONS LEARNT: Disseminating guidelines and results of an audit on endoscopic surveillance in Barrett's oesophagus had no effect on practice. Introducing coordinators who proactively managed the process greatly improved adherence to guidelines.
