In gastroparetic patients, ICC loss in the pylorus is twice as common as in the antrum and fibrosis in the pyloric smooth muscle is nearly three times more common than the antrum. These findings can provide one explanation for pyloric dysfunction which is a contributing factor to the pathophysiology of gastroparesis.

Patient: Female, 82Final Diagnosis: AchalasiaSymptoms: Nocturnal regurgtation • weight lossMedication: —Clinical Procedure: Esophageal stentingSpecialty: Gastroenterology • HepatologyObjective: Unusual or unexpected effect of treatmentBackground:Pneumatic dilatation is one of the most effective methods for treating achalasia. Esophageal perforation is the most serious complication after pneumatic dilatation and has been reported to occur in the range of 1 to 4.3%. The appropriate management of esophageal perforation can range from conservative medical treatment to surgical intervention.Case Report: We report a case of an 82-year-old male who had an 8 month history of dysphagia for solid and liquids, a 10 lb weight loss and nocturnal regurgitation. The diagnosis of achalasia was established by endoscopic; barium and manometric criteria. He underwent a pneumatic dilation with a 30 mm Rigiflex balloon. A confined or limited esophageal perforation projecting into the mediastinum and located 1–2 cm above the diaphragm was confirmed by a gastrografin swallow study performed immediately after the procedure. There was some accompanying epigastric abdominal pain. Patient was treated later that day by placing a fully covered metallic esophageal stent in addition to antibiotics, proton pump inhibitor, and fasting. Patient was discharged home 3 days later able to eat liquid-soft foods. Follow up endoscopy 2 weeks later and a gastrografin swallow showed a completely healed perforation and the stent was removed. Symptomatically he has done well, with no dysphagia or heartburn at six and twelve months follow up.Conclusions:Early esophageal stenting for esophageal perforation after pneumatic dilation for achalasia is a treatment option which accelerates healing shortens recovery period, as well as decreasing hospital stay and costs.
