Surgery for mesenchymal neoplasms of the esophagus: experience over 2 decades from a tertiary healthcare center in India

Mesenchymal tumors are the most common benign neoplasms of the esophagus. Owing to the rarity of these neoplasms, there is a dearth of literature regarding their diagnosis and management. Our 2-decade-long experience in managing these neoplasms surgically is presented. Relevant clinical data of all patients with esophageal mesenchymal neoplasms (EMNs) managed between January 2000 and May 2020 were retrospectively collected from a prospectively maintained esophageal diseases database in the Department of GI Surgery, AIIMS, New Delhi (India). Special emphasis was given to data pertaining to diagnostic evaluation of patients, type of surgery done (enucleation vs. resection), postoperative outcomes, histopathology and long-term follow-up. Nineteen patients (12 females; age 15–66 years) underwent surgery for EMN (mean tumor size 7.6 cm; enucleation 10; resection 9). On histopathological examination, 17 cases were noted to be benign esophageal leiomyomas and 2 were identified as gastrointestinal stromal tumors. There was no perioperative mortality. All cases were followed up for a median duration of 6 years (range 1–19 years) with no evidence of recurrence in any case. Though EMNs are uncommon, they are mostly benign, and the long-term outcomes after surgical excision are gratifying.
