Background Impaction of jujube pits in the upper gastrointestinal (GI) tract is a special clinical condition in the northern Chinese population. Endoscopic removal is the preferred therapy, but there is no consensus on the management strategies. We reported our individualized endoscopic strategies on the jujube pits impacted in the upper GI tract. Methods In this retrospective study, we included 191 patients (male: 57; female: 134) who presented to our hospital with ingestion of jujube pits between January 2015 and December 2017. Demographic information, times of hospital visiting, locations of jujube pits, endoscopic procedures, post-extraction endoscopic characteristics were analyzed. Management strategies including sufficient suction, repeated irrigation, jejunal nutrition and gastrointestinal decompression were given based on post-extraction endoscopic characteristics and impacted locations. Results Peak incidence was in the second quarter of each year (85/191 cases, 44.5%). Among the 191 cases, 169 (88.5%) showed pits impaction in the esophagus, 20 (10.5%) in the prepyloric region and 2 (1.0%) in the duodenal bulb. A total of 185 patients (96.9%) had pits removed with alligator jaw forceps, and 6 (3.1%) underwent suction removal with transparent caps placed over the end of the endoscope to prevent injury on removal of these pits with two sharp painted edges. Post-extraction endoscopic manifestations included mucosal erosion (26.7%), mucosa laceration (24.6%), ulceration with a white coating (18.9%) and penetrating trauma with pus cavity formation (29.8%). All patients received individualized endoscopic and subsequent management strategies and showed good outcomes. Conclusions Individualized endoscopic management for impacted jujube pits in the upper GI tract based on post-extraction endoscopic characteristics and impacted locations was safe, effective, and minimally invasive.

It is currently unclear whether endoscopic papillary balloon dilation (EPBD) is associated with increased severe postendoscopic retrograde cholangiopancreatography pancreatitis (PEP)-related morbidity owing to conflicting reports. This study aimed to investigate whether EPBD increases the risk of PEP and hyperamylasemia. Clinical data of patients with choledocholithiasis, treated at the Second Affiliated Hospital of Harbin Medical University from January 2015 to December 2016 were analyzed. Patients were divided into the EPBD group and endoscopic sphincterotomy (EST)+EPBD group, and their characteristics and PEP and hyperamylasemia incidences were compared. Incidences related to dilated balloon diameter were also analyzed. There were no significant differences in patient characteristics and the incidences of PEP (2.6% vs. 0%; P = 0.257) and hyperamylasemia (4.4% vs. 5.6%; P = 0.954) between the 2 groups. Results were similar even with different balloon dilatations. EPBD without endoscopic sphincterotomy did not increase the risk of PEP and hyperamylasemia. It is a safe option for choledocholithiasis patients.
