Preoperative assessment of esophageal pathology

Panmural esophagitis results in esophageal thickening and shortening and prevents adequate reduction of a hernia. Twenty patients with panmural esophagitis, treated by Belsey repair, have been followed up for more than 5 years; 9 of them remain asymptomatic and 11 have symptomatic reflux, 7 of whom have required further surgery. Belsey also has reported a 45 per cent recurrence rate in patients with this type of disease. Preoperative recognition of panmural esophagitis allows a planned surgical approach and the use of a surgical technique designed for the management of an irreducible hernia. The ability to predict these changes was studied in 124 patients, who were evaluated by history, radiology, endoscopy, and manometry prior to transthoracic hernia repair. The esophagus was inspected at operation to determine the presence of panmural changes. History was of no value in assessment. Radiologically, a large and irreducible hernia was associated with panmural changes, but these changes also occurred in the absence of ulceration. Manometric studies allowed accurate prediction of mural changes. Over 90 per cent of patients with panmural esophagitis have more than 40 per cent disordered motor activity (DMA) in the distal part of the esophagus, and 75 per cent of such patients have more than 60 per cent DMA. Combining these investigative data allowed the accurate prediction of panmural changes in 90 per cent of the 124 patients.
