Double balloon enteroscopy to retrieve an accidentally swallowed dental reamer deep in the jejunum

Balloon-Assisted Enteroscopy for Retrieval of Small Intestinal Foreign Bodies: A KASID Multicenter Study

Background and Aims

Balloon-assisted enteroscopy (BAE) can be used to retrieve small intestinal foreign bodies (FBs). Here, we aimed at exploring the clinical usefulness of BAE for the retrieval of small intestinal FBs.

Methods

We retrospectively reviewed the medical records of 34 patients who underwent BAE to retrieve small intestinal FBs at 3 tertiary referral centers between April 2005 and June 2017.

Results

The retained materials included capsule endoscopes (CEs; n = 18 [52.9%]), self-expandable metal stents (SEMSs; n = 5 [14.7%]), biliary drainage catheters (n = 4 [11.8%]), gallstones (n = 3 [8.8%]), an embolization coil (2.9%), a needle, an intragastric bariatric balloon, and a razor blade. FBs were located or stuck in the ileum (n = 17 [50%]), jejunum (n = 16 [47.1%]), and an undetermined small intestinal segment (n = 1). Seventeen cases of FBs (50%; 7 CEs, 3 biliary drainage catheters, 3 SEMSs, 2 gallstones, 1 intragastric balloon, and 1 needle) were successfully retrieved enteroscopically. FBs of 4 asymptomatic patients (3 CEs and 1 razor blade) passed spontaneously. The remaining 13 patients underwent surgery for persistent or symptomatic FBs: 12 were successfully removed and 1 CE removal procedure failed due to severe peritoneal adhesions. The presence of symptoms was the only independent predictor of successful retrieval using BAE (odds ratio 13.40, 95% confidence interval 1.10–162.56, P = 0.042). BAE-related complications such as bowel perforation and acute pancreatitis occurred in 2 patients (5.9%).

Conclusions

BAE can be the first option for FB removal in the small intestine. The presence of symptoms was associated with successful enteroscopic retrieval.

Foreign Body Penetration through Jejunal Loops Causing Renal Artery Thrombosis and Renal Infarct

Foreign body ingestion is common, although perforation after ingestion is rare. We report a case of an ingested sharp wooden stick that perforated the proximal jejunum toward the renal vasculature, causing segmental renal artery thrombosis and renal infarct. The patient presented with severe abdominal pain and vomiting. A computed tomography scan revealed a linear opacity corresponding to the foreign body. The wooden stick was removed endoscopically through deep-push enteroscopy with a rat-tooth forceps. We report this unique case of perforation by a foreign body through the proximal jejunum to the left kidney, which was managed endoscopically.

Successful Removal of a Screw Nail in the Jejunum Using Double-Balloon Enteroscopy

The vast majority of foreign bodies (FBs) that enter the stomach pass through the gastrointestinal tract spontaneously. When the FB enters the small bowel-beyond the reach of conventional endoscopy-daily radiographs are needed to ensure its safe passage. However, endoscopic intervention is an appropriate management strategy for a sharp-pointed FB, because sharp FBs have a higher risk of intestinal perforation. We describe here a case in which a 1.5-cm, sharp-pointed screw nail in the proximal jejunum was removed successfully by double-balloon enteroscopy from a 19-year-old-male with autism. This case adds to the growing body of evidence demonstrating the value of therapeutic double-balloon enteroscopy in the field of FB ingestion.

A case of penetration of the intestinal wall by a soft-shelled turtle bone successfully removed with double-balloon endoscopy

A 62-year-old male was admitted to our hospital due to left lower abdominal pain. Three days before admission, he ate seafood in a Japanese restaurant. Two days before admission, he suffered from intermittent left lower abdominal pain. One day before admission, he developed a high fever and subsequently visited our hospital the following day. Localized tenderness and rebound pain were observed in the left lower abdomen, and C-reactive protein was elevated. Computed tomography revealed a linear high-density object in the distal portion of the small intestine accompanied by edema of the wall, suggesting penetration by something like a fishbone. On the ninth hospital day, double-balloon endoscopy was performed via the transanal route. Yellow foreign material was found in the ileum and was then successfully removed with biopsy forceps. The removed material measured 3 mm in width, 3 cm in length and was slightly curved. It proved to be a bone of the forefoot of a soft-shelled turtle, which had been included on the menu of the restaurant. The patient was completely cured and discharged on the 14th hospital day.

Double-balloon endoscopy in clinical practice: where are we now?

Double-balloon endoscopy (DBE) was developed in 2000 for the diagnosis and treatment of small bowel diseases. Although use rates still differ between Eastern and Western countries, DBE quickly reached a broad global diffusion. Together with capsule endoscopy (CE), DBE represented 'a revolution' for the management of small bowel diseases because of its therapeutic capabilities. At present, the main indications for DBE in clinical practice are obscure gastrointestinal bleeding, Crohn's disease and familial polyposis. In the setting of obscure gastrointestinal bleeding, DBE seems to have similar diagnostic performances as capsule endoscopy, but it allows for a more definitive diagnosis and the treatment of identified lesions. The main contribution of DBE in the management of Crohn's disease patients is its therapeutic capabilities. Indeed, several recently published studies have suggested that endoscopic dilation of small bowel strictures can delay or, in the near future, could even replace surgical interventions. Also, for patients with familial polyposis syndromes, DBE can represent a viable alternative to small bowel surgery. The complication rate of DBE appears to be low; major complications, such as pancreatitis, bleeding and perforation, have been reported in approximately 1% of all diagnostic DBE whereas the complication rate for therapeutic procedures is about 5%.
