PURPOSE The aim of this study is to present a surgical technique used to treat epiphora secondary to difficult cases of lacrimal pathway obstruction after fractures, previous surgery or anatomic abnormalities. METHODS From January 2001 to December 2002 we treated 27 patients with complicated lacrimal pathway obstruction secondary to fractures (10 cases), previous nasal surgery (4 cases), fail...

PURPOSE To determine the factors affecting the ability to cross malignant biliary obstructions in percutaneous transhepatic interventions. MATERIALS AND METHODS In this study, 256 patients with 310 obstructive malignant biliary lesions from May 2006 to January 2009 were analyzed retrospectively. All of the patients had undergone percutaneous transhepatic cholangiography and intervention. Obst...

Z Jr. CFTR expression but not Cl-transport is involved in the stimulatory effect of bile acids on apical Cl-/HCO 3-exchange activity in human pancreatic duct cells. pancreatic duct cells using a Sendai virus vector. A new experimental method to study the acid/base transporters and their regulation in lacrimal gland ductal epithelia.

BACKGROUND Primary ductal adenocarcinomas of the lacrimal gland are very rare. This neoplasm shares some histological and immunohistochemical similarities with salivary duct carcinoma. CASE PRESENTATION Here, we present a case of a 55-year-old Moroccan man with lacrimal gland adenocarcinoma. He underwent orbital exenteration with lymph nodes dissection and ipsilateral parotidectomy. After sur...

PURPOSE To report the finding of nasolacrimal drainage system obstruction associated with radio iodine therapy and to review clinical data and the surgical treatment outcome of this rare complication. METHODS We retrospectively analyzed ophthalmological data of patients with history of thyroid carcinoma that underwent radioactive iodine I-131 therapy and were referred to lacrimal surgery. R...

Primary diffuse large B-cell lymphoma of the lacrimal sac is rare. Herein we report a 55-year-old female presented with epiphora in the right eye. Distention of the lacrimal sac secondary to nasolacrimal duct obstruction was observed. She was scheduled for external dacryocystorinostomy for the next month. When she came for surgery, a growing mass was recognised over the lacrimal sac region. On ...

AIMS To determine the current bacteriology of lacrimal duct obstruction (LDO) and to relate the bacteriological findings to the type of symptoms. METHODS 127 samples were obtained from the lacrimal sac in 118 consecutive adult patients with LDO, including nine bilateral cases. RESULTS Altogether, 156 isolates were recovered from the 127 samples cultured. Cultures were positive from 84% of t...

The most widespread treatment for dry eyes in clinical practice is an instillation containing artificial tear fluid. When an instillation does not ameliorate dry eye, we use punctal plugs. The insertion of punctal plugs is an eminent curative that positively improves the corneal and conjunctival epithelial disorders and the amount of lacrimal fluid accumulated in the conjunctival sac. We shall ...

Aim. To report on the use of indocyanine green (ICG) during surgical removal of pediatric orbital lacrimal duct cysts. Method. We conducted a retrospective review of our cases of surgical excision of orbital lacrimal duct cysts using intraoperative injection of indocyanine green (ICG), which was used following inadvertent cyst rupture and volume loss. The dye allowed complete cyst visualization...
