Foreign body reaction to a metal clip causing a benign bile duct stricture 16 years after open cholecystectomy: report of a case

Acute obstructive cholangitis due to fishbone in the common bile duct: a case report and review of the literature

Background

Choledocholithiasis is an endemic condition in the world. Although rare, foreign body migration with biliary complications needs to be considered in the differential diagnosis for patients presenting with typical symptoms even many years after cholecystectomy, EPCP, war-wound, foreign body ingestion or any other particular history before. It is of great clinical value as the present review may offer some help when dealing with choledocholithiasis caused by foreign bodies.

Case presentation

We reported a case of choledocholithiasis caused by fishbone from choledochoduodenal anastomosis regurgitation. Moreover, we showed up all the instances of choledocholithiasis caused by foreign bodies published until June 2018 and wrote the world’s first literature review of foreign bodies in the bile duct of 144 cases. The findings from this case suggest that the migration of fishbone can cause various consequences, one of these, as we reported here, is as a core of gallstone and a cause of choledocholithiasis.

Conclusion

The literature review declared the choledocholithiasis caused by foreign bodies prefer the wrinkly and mainly comes from three parts: postoperative complications, foreign body ingestion, and post-war complications such as bullet injury and shrapnel wound. The Jonckheere-Terpstra test indicated the ERCP was currently the treatment of choice. It is a very singular case of choledocholithiasis caused by fishbone, and the present review is the first one concerning choledocholithiasis caused by foreign bodies all over the world.

Iatrogenic bile duct Injury with a retained T-tube in common bile duct for 10 years: A case report

RATIONALE

Bile duct injury (BDI), a major complication of cholecystectomy, usually needs hepaticojejunostomy or primary repair over T-tube in severe cases. There were few cases about retained fragments of T-tube. Whereas, intact T-tube retained in common bile duct (CBD) for years after BDI was very rare.

PATIENT CONCERNS

A 55-year-old female complaining of a retained T-tube in the right upper quadrant for 10 years with bilious exudation for 3 months.

DIAGNOSIS

Based on the medical history of reoperation after the initial laparoscopic cholecystectomy (LC), the retained T-tube, the bilious exudation, and the feature of image modalities, she was diagnosed with retained biliary T-tube, biliary leak, hepatolithiasis, and BDI.

INTERVENTIONS

After nonsurgical management at local hospitals, the patient had her indwelling T-tube removal during laparotomy in our center finally. During this procedure, bile duct exploration, hilar bile ducts reconstruction, and primary Roux-en-Y hepaticojejunostomy were performed.

OUTCOMES

Unfortunately, bile leakage occurred postoperatively. After drainage of the peritoneal bilious fluid, the patient recovered gradually without further complication.

LESSONS

T-tube in CBD could act as nidus for stone formation after long-time placement. As a result of gradual stone formation on T-tube, severe hepatic ducts dilatation may occur without the presence of jaundice. Timely follow-up and proper surgical intervention should be suggested for patients with T-tube placement or iatrogenic BDI to avoid further impacts.

[Foreign body granuloma simulating malignant disease in the biliary tract]

Non-absorbable suture materials, such as silk, are able to form foreign body granulomas and stones and consequently their use should be avoided in surgical procedures in the biliary tract. We present the case of a patient who underwent surgery for a probable Klastkin tumor. During the intervention, a 1.5-cm tumor, with firm consistency, extrinsic to the biliary tract was found; the mass was extirpated with no compromise to the biliary tract. Macroscopic examination revealed suture (silk) material. The histopathological report described an inflammatory tumor, composed essentially of macrophages and foreign body giant cells, and identified a suture within the cell cytoplasm. The interest of this case lies in the rarity of this entity, the difficulty of preoperative diagnosis, and its possible confusion with other anatomic and clinical syndromes.
