Review
Several diseases originate from bile duct pathology. Despite studies on these diseases, certain etiologies of some of them still cannot be concluded. The most common disease of the bile duct in newborns is biliary atresia, whose prognosis varies according to the age of surgical correction. Other diseases such as Alagille syndrome, inspissated bile duct syndrome, and choledochal cysts are also time-sensitive because they can cause severe liver damage due to obstruction. The majority of these diseases present with cholestatic jaundice in the newborn or infant period, which is quite difficult to differentiate regarding clinical acumen and initial investigations. Intraoperative cholangiography is potentially necessary to make an accurate diagnosis, and further treatment will be performed synchronously or planned as findings suggest. This article provides a concise review of bile duct diseases, with interesting cases.

Review
Bile duct stone disease is the most common causes of nonmalignant bile duct obstructions. The range of common bile duct stone formation in patients with cholecystectomy is 3 to 14.7%. Hepatolithiasis, although endemic in some parts of the world, is a rare disease that is difficult to manage. Endoscopic intervention is accepted as the first-line management of common bile duct stones. However, when the bile duct cannot be cannulated for various reasons, the endoscopic procedure fails. In this circumstance, percutaneous approach is an alternative technique for the nonsurgical treatment of bile duct stones. This article reviews the indications, technique, outcomes, and complications of the percutaneous treatment of bile duct stone disease.

This case report describes the first Danish case of endoluminal radiofrequency ablation (RFA) of malignant biliary obstruction due to a Klatskin tumour in a 59-year-old male undergoing neoadjuvant therapy. The treatment was interrupted several times due to recurrent occlusions of the bile duct stents. The patient was offered endoluminal RFA of the central bile ducts in order to reduce his tumour burden and possibly achieve longer stent patency, so the palliative therapy could be resumed. The procedure was performed successfully without any adverse events achieving access to previously occluded left hepatic duct.

Review
Cholangiocarcinoma (CCA) is a rare cancer of the bile duct epithelium, and in the last few decades its incidence rate has been increasing. It is associated with a high mortality rate due to late diagnosis and its aggressive nature. Many risk factors have been identified; some are more common in certain regions than others. CCA can be classified according to its anatomical location or macroscopic growth pattern, the latter being most helpful for imaging interpretation. Clinical features can vary from obstructive-like symptoms to nonspecific symptoms, such as weight loss and malaise. Imaging, specifically MRI/MRCP, is crucial in diagnosing CCA, staging, and treatment planning. Surgery with chemotherapy is the mainstay treatment option, and other palliative treatment options exist for those who have unresectable disease.

Review
Primary acquired nasolacrimal duct obstruction, or PANDO, is a common adult lacrimal drainage disorder. The current treatment modality of dacryocystorhinostomy to bypass the obstructed nasolacrimal duct has excellent outcomes. However, the understanding of the disease etiopathogenesis needs to be revisited. There are not many studies that specifically assessed any hypothesis or ones that convincingly put forth the presumed or confirmed interpretations regarding the PANDO pathogenesis or the mechanisms or pathways involved therein. Histopathological evidence points to recurrent inflammation of the nasolacrimal duct, subsequent fibrosis, and the resultant obstruction. The disease etiopathogenesis is considered multifactorial. Several implicated suspects include anatomical narrowing of the bony nasolacrimal duct, vascular factors, local hormonal imbalance, microbial influence, nasal abnormalities, autonomic dysregulation, surfactants, lysosomal dysfunction, gastroesophageal reflux, tear proteins, and deranged local host defenses. The present work reviewed the literature on the etiopathogenesis of primary acquired nasolacrimal duct obstruction (PANDO) to gain insights into the present state of the understanding and the high-value translational implications of precisely decoding the disease etiology.

Review
The ampulla of Vater is a small projection formed by the confluence of the main pancreatic duct and common bile duct in the second part of the duodenum. Primary ampullary adenocarcinoma is a rare malignancy, accounting for only 0.2% of gastrointestinal cancers and approximately 7% of all periampullary cancers. Jaundice from a biliary obstruction is the most common symptom of ampullary adenocarcinoma. In the early stages, radical pancreatoduodenectomy is the standard surgical approach. On the other hand, no randomized controlled trial has provided evidence to guide physicians on the choice of adjuvant/palliative chemotherapy because of the rarity of the disease and the paucity of related research. This paper reports the biology, histology, current therapeutic strategies, and potential future therapies of ampullary adenocarcinoma.

Review
Biliodigestive anastomosis between the extrahepatic bile duct and the intestine for bile duct disease is a gastrointestinal reconstruction that abolishes duodenal papilla function and frequently causes retrograde cholangitis. This chronic inflammation can cause liver dysfunction, liver abscess, and even bile duct cancer. Although research has been conducted for over 100 years to directly repair bile duct defects with alternatives, no bile duct substitute (BDS) has been developed. This narrative review confirms our understanding of why bile duct alternatives have not been developed and explains the clinical applicability of BDSs in the near future. We searched the PubMed electronic database to identify studies conducted to develop BDSs until December 2021 and identified studies in English. Two independent reviewers reviewed studies on large animals with 8 or more cases. Four types of BDSs prevail: Autologous tissue, non-bioabsorbable material, bioabsorbable material, and others (decellularized tissue, 3D-printed structures, ). In most studies, BDSs failed due to obstruction of the lumen or stenosis of the anastomosis with the native bile duct. BDS has not been developed primarily because control of bile duct wound healing and regeneration has not been elucidated. A BDS expected to be clinically applied in the near future incorporates a bioabsorbable material that allows for regeneration of the bile duct outside the BDS.

A 35-year-old woman underwent left external dacryocystorhinostomy (DCR) following a recent bout of left acute dacryocystitis. She had a right DCR 14 years earlier. Her relatively young age of presentation prompted suspicion of secondary nasolacrimal duct obstruction and, although the left lacrimal sac appeared macroscopically normal peroperatively, a lacrimal sac biopsy was taken. Histopathology revealed florid chronic inflammation, with abundant granular brown pigment and polarisable crystals suggestive of an exogenous material in the lacrimal sac mucosa compatible with mascara. After initial improvement, her epiphora has recurred 1-year postoperatively, but her ocular discharge has resolved. Mascara-induced conjunctival pigmentation is well established. However, there are very few published reports of nasolacrimal duct obstruction due to mascara. Since cosmetic application of mascara and kohl eyeliner is widespread, patients and practitioners should be aware of their potential to migrate into the lacrimal apparatus and cause chronic inflammation with secondary nasolacrimal duct obstruction.
