Gastric ectopic pancreas (GEP) is a rare submucosal lesion that is usually difficult to diagnose histologically by biopsy, and endoscopic ultrasonography (EUS) has been used in the diagnosis of gastric submucosal tumors (SMTs). Surgical resection is the conventional standard strategy for the treatment of SMTs in the past, and endoscopic submucosal dissection (ESD) has become an important minimally invasive treatment technique. However, there is still a lack of studies on the two techniques for the treatment of GEP.
At present, most of the studies on GEP are limited to case reports, without large sample size reports, and its treatment has not been widely discussed.
The aim of this study was to describe the EUS features of GEP and to evaluate the value of laparoscopic resection (LR) vs ESD in the treatment of GEP.
We retrospectively analyzed 49 patients with GEP who underwent lesion resection. The characteristics of EUS, clinical characteristics and the characteristics of the two treatment methods were analyzed.
Of the patients, 43 underwent ESD, and 6 underwent LR. GEP mostly originates from the submucosa, accompanied by umbilical depression, and often presents with abdominal pain as the first symptom. There was no significant difference in operative time, hospitalization time, hospitalization cost and time to resume eating between the two groups. LR was more prone to larger and deeper lesions, accompanied by more blood loss.
GEP has significant characteristics under EUS. Both LR and ESD are good choices for the treatment of GEP.
EUS can serve as a noninvasive technique for diagnosing GEP, and clinical doctors can choose ESD or LR based on the actual situation of the patient.
