  ABSTRACT: OBJECTIVES It is generally believed that Heller's cardiomyotomy (HCM) cannot improve dysphagia in patients with marked dilatation and axis deviation or sigmoid oesophagus. Conventional management for sigmoid oesophagus has been oesophagectomy. We report our surgical experience in the management of 8 patients with sigmoid oesophagus with laparoscopic HCM.METHODS Eight patients with sigmoid oesophagus were retrospectively identified and their records were reviewed for symptomatic outcome evaluation following laparoscopic HCM with an antireflux procedure. Preoperative and postoperative, oesophageal and respiratory symptoms and quality of life scoring of achalasia were recorded.RESULTSThe mean age was 35.5 (range 25-57) years. Males and females were equally distributed. All patients had dysphagia as their chief presenting complaint. The median duration of dysphagia was 55 (range 18-180) months. All the patients had a poor quality of life. Four patients also had chronic cough. All 8 patients underwent laparoscopic HCM with an antireflux procedure. The mean duration of operation was 203.7 min. There were no mortalities and no major postoperative complications. At a median follow-up of 19.5 (range 6-45) months, there was a significant improvement of dysphagia and regurgitation scores with P-values of 0.014 and 0.008, respectively. Quality of life also significantly (P = 0.005) improved post-surgery. Chronic cough resolved in all the 4 patients (100%) following cardiomyotomy.CONCLUSIONS Laparoscopic HCM with an antireflux procedure provides significant symptom relief in patients with sigmoid oesophagus and may be considered as the first-line treatment option in such patients. Oesophagectomy should be reserved for patients with a failed cardiomyotomy.

  ABSTRACT: Patients with achalasia have respiratory symptoms due to chronic microaspiration. Achalasia can lead to radiological and functional changes in the lung. We studied the effect of either balloon dilatation or laparoscopic Heller's cardiomyotomy on the reversal of these changes in the lung. Thirty patients with achalasia were included in this study. Oesophageal symptoms and pulmonary symptoms were recorded. Pulmonary function tests (PFTs) were done at baseline and at the end of 6 months. High-resolution computed tomography of the chest was performed prior to treatment and repeated 6 months after treatment if found abnormal at the initial evaluation. The mean age of the patients was 30.97 years and mean duration of symptoms was 22.5 months. Fifteen patients (50%) had respiratory symptoms, nocturnal cough being the commonest symptom in 13 (43.3%). Thirteen patients (43.3%) had parenchymal lung changes on high-resolution computed tomography (HRCT). Eight patients (28.5%) had functional abnormalities in the lungs in the form of restrictive airway disease. Nineteen patients opted for Laproscopic Heller's cardiomyotomy, while 11 patients underwent pneumatic dilatation. Six months after treatment, the respiratory symptoms resolved in all except two patients (13.3%). Four patients (66.6%) with active lung changes at HRCT showed resolution at 6 months. There was improvement in functional parameters on PFT evaluation with normalization of PFT in one patient. Pulmonary symptoms as well as radiological and functional abnormalities are common in patients with achalasia. Treatment in the form of pneumatic dilatation or Lap cardiomyotomy improves pulmonary symptoms.
