Esophageal diverticula: from diagnosis to therapeutic management-narrative review.

BACKGROUND AND OBJECTIVE

Esophageal diverticulum (ED) is a relatively rare condition, characterized by high etio- and pathophysiological versatility, with an uncommon clinical impact, consequently requiring a complete and complex diagnostic evaluation, so that the therapeutic decision is "appropriate" to a specific case. The aim of the paper is, therefore, a reassessment of the diagnostic possibilities underlying the establishment of the therapeutic protocol and the available therapeutic resources, making a review of the literature, and a non-statistical retrospective analysis of cases hospitalized and operated in a tertiary center.

METHODS

Thus, classical investigations (upper digestive endoscopy, barium swallow) need to be correlated with complex, manometric, and imaging evaluations with direct implications in therapeutic management. Moreover, in the absence of a precise etiology, the operative indication needs to be established sparingly, with the imposition of the identification and interception of the pathophysiological mechanisms through the therapeutic gesture.

KEY CONTENT AND FINDINGS

The identification of the pathophysiological mechanisms is mandatory for the management of diverticular disease, the result obtained-restoring swallowing and comfort/good quality of life in the postoperative period-is directly related to the chosen therapeutic procedure. In addition, management appears to be a difficult goal in the context of the low incidence of ED but also of the results that emphasize important differences in the reports in the medical literature. Although ED is a benign condition, surgical techniques are demanding, impacted by significant morbidity and mortality. The causes of these results are multiple: possible localizations anywhere in the esophagus, diverticulum size/volume from a few millimeters to an impressive one, over 10-12 cm, metabolic impact in direct relation to the alteration swallowing, numerous diverticular complications but, perhaps most importantly, alteration of the quality of the diverticular wall by inflammatory phenomena, with an impact on the quality of the suture.

CONCLUSIONS

The accumulation of cases in a tertiary profile center, with volume/hospital, respectively volume/surgeon + gastroenterologist could be a solution in improving the results. One consequence would be the identification of alternative solutions to open surgical techniques, a series of minimally invasive or endoscopic variants can refine these results.
