The existence, diagnosis and treatment of short esophagus is one of the controversies of the past which has recently re-emerged. The missed diagnosis of short esophagus and the consequent inadequacy of treatment is one of the major causes of failure of antireflux surgery.

The daily clinical practice of surgeons dedicated to therapy of esophageal diseases could take advantage of the definition of frequency, preoperative predictors, intraoperative management and post operative outcomes of cases of foreshortened esophagus, in order to offer the patient affected by GERD the elements necessary for a conscious choice of therapy and to plan the best performance of the surgical procedure.

Aims of the Study To define the percentage of cases among the total of antireflux procedures performed for type II-IV hiatus hernia, in which, after standard isolation of the ge junction and dissection of the mediastinal esophagus at least two centimetres of esophagus can not be replaced without any applied tension below the apex of the diaphragmatic hiatus.

Primary Outcome Measures:
  • Global Results [ Time Frame: minimum 12 months ]

    Pre-operatively, patients routinely underwent the symptoms assessment, barium swallow, upper gastro-intestinal endoscopy and esophageal manometry.

    The type and severity of symptoms and the grade of reflux esophagitis were scored using a questionnaire with semi-quantitative scales (form 0 = absence of symptoms or esophagitis, to 3 = severe symptoms and esophagitis.For the surgical results an evaluation scale , from "excellent" to "poor", was used.

Enrollment: 34
Study Start Date: January 1995
Study Completion Date: January 2012
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Patients submitted to laparoscopic surgery for Type II-IV hiatus hernia
Procedure: laparoscopic surgery
Nissen fundoplication; Collis Gastroplasty.
