Introduction

Suspected foreign body ingestion and food bolus impaction are common indications for urgent esophagogastroduodenoscopy. Nevertheless, most of the ingested foreign bodies (80 to 90%) pass spontaneously throughout the gastrointestinal tract. In 2022, the Decision-To-Scope (DTS) Score was developed, revealing an excellent accuracy in predicting foreign bodies in the esophagus.

Aims & Methods

Our aim was to prospectively evaluate the diagnostic accuracy of the DTS-Score.
We have prospectively included consecutive patients admitted for suspected foreign body in the upper gastrointestinal tract, for a 6-month period. Previously to endoscopic evaluation, the DTS-score - time since ingestion < 6 hours (+1pt); absence of any meal since the suspected ingestion (+2pts); dysphagia (+3pts); odynophagia (+1pt) and drooling (+4pts) - was applied in each patient. The maximal possible value was 11 points, with a DTS-Score ≥5 being considered to assign a high probability of endoscopic confirmation of the foreign body.

Results

Final sample included 47 patients, from which 26 (55.3%) were females, with a mean age of 60±16 years. From these, most (n=42; 91.5%) were evaluated for accidental ingestion of food-related foreign bodies (fish or chicken bones) or suspected food bolus impaction. A DTS-Score ≥5 was calculated in 11 (23.4%) of the patients, with an esophageal foreign body being confirmed in 12 (25.5%) of them. DTS-score presented an excellent accuracy in predicting the endoscopic confirmation of a foreign body in the esophagus (AUC=0.94; 95%CI 0.85-1.00; p<0.001). The originally defined cut-off (DTS-Score ≥5) presented a specificity of 97.1%, a sensitivity of 83.3%, a positive predictive value of 90.9% and a negative predictive value of 94.4%.

Conclusion

When prospectively applied, the DTS-score demonstrated an excellent acuity in stratifying the probability of endoscopic confirmation of a suspected foreign body in the esophagus. This tool may be included in future clinical algorithms for suspected foreign bodies ingestion.

Introduction

Complete excision of upper gastrointestinal sub-epithelial lesions (SELs) eliminates diagnostic uncertainty, obviates the need for surveillance and may be necessary for definitive diagnosis and management. Current guidelines lack precision and cohesion, and surgery is associated with significant morbidity. Herein, we describe and report on the outcomes of our SEL algorithm for endoscopic (SAFE) resection.

Aims & Methods

SELs were enrolled prospectively over 115 months until March 2023. All underwent axial (CT) imaging and endoscopic-ultrasonography (EUS) to exclude a large exophytic component or invasion into local structures, and assess for muscularis propria involvement.

Results

106 SELs were resected (mean age 60.6±13.4, 51.9% male; 41 oesophageal, 65 gastric). Oesophageal SELs underwent ESD (n=22) or STER if MP involvement was suspected (n=19). Gastric SELs underwent STER (n=6 at cardia), ESD (n=47) or exposing-EFTR (n=12). Technical success was 97.6% and 92.3% respectively. Five (7.7%) were completed laparoscopically due to deep and broad full-thickness involvement. Five (7.7%) required laparoscopic gastrotomy and surgical retrieval after successful resection and closure due to a large lesion size (mean 47 mm). There was no delayed bleeding, perforation or recurrence at a median of 13 months.

Conclusion

Upper GI SELs are effectively and safely treated by endoscopic resection. The SAFE approach provides a framework that facilitates structured decision-making. Oesophageal SELs suspected to involve the MP should undergo STER. Gastric SELs can be best managed by ESD with a view to proceed to exposing-EFTR. A laparoscopic UGI surgeon should be available in case surgical retrieval of the specimen or laparoscopic completion is required.
