Background: To report the clinical experience and analysis of our results with Ritleng intubation system in patients with congenital and acquired nasolacrimal duct obstruction. Methods: Silicone intubation with the Ritleng lacrimal system was performed in 17 patients (20 eyes) from March 2001 to March 2003 to relieve nasolacrimal duct obstruction following the failure of nasolacrimal duct probi...

BACKGROUND Controversy exists regarding the treatment of infants with symptomatic nasolacrimal duct obstruction. One philosophy advocates "early" nasolacrimal duct probing, generally in the office. An alternate strategy advocates medical management until the infant is approximately 12 months old to allow for spontaneous resolution, with those with persistent nasolacrimal duct obstruction usuall...

BACKGROUND Conventional transabdominal ultrasound usually fails to visualize parts of the ureter or extrahepatic bile duct covered by bowel gas. In this study, we propose a new method for gaining acoustic access to the ureters and extrahepatic bile duct to help determine the nature of obstruction to these structures when conventional transabdominal ultrasound fails. METHODS The normal saline ...

Persistent omphalomesenteric duct as a cause of small-bowel obstruction is an exceptional finding. A neonate presented with occlusion due to intestinal prolapse through a persistent omphalomesenteric duct. Remnants of the duct were successfully resected, and the postoperative course was uneventful. We discuss the presentation of omphalomesenteric duct and its management.

Malignant obstructive jaundice caused by tumor obstruction at the head of pancreas, peri-ampullary area, bile duct or gall bladder, and hilar lymphadenopathy carries considerable morbidity and mortality (Fig. 2.1a, b ). Biliary obstruction can lead to severe itching, and prolonged obstruction leads to impaired immune (both humoral and cellular) defense mechanisms predisposing the patient to inc...

Objective: To study the age and the sex distribution among the primary and secondarily acquired Nasolacrimal duct obstruction . Methods: we conducted a prospective observational study among randomly selected 100 patients presented with epiphora to ENT department during 2year period ie; from march 2013-march 2015. After confirming presence of Nasolacrimal duct obstruction (NLDO) by opthalmologic...

Bile is normally sterile. Bactibilia occurs when bile flow is impaired and bacteria gain access to the biliary duct by the papilla or portal circulation. Bile duct obstruction leads sequentially to increase in intra biliary pressure, infection of bile, cholangiovenous and cholangiolymphatic reflux leading to bacteremia [1-3]. The bacteria described commonly in biliary tract infections include E...

Variations in the adult male reproductive system among different groups of Hymenoptera offer characteristics that help studies on behavior and phylogenetics. The objective of this study was to describe the adult male reproductive system of three Trypoxylon (Trypargilum) species. For that, tissues were disseced, fixed in 2.5% glutaraldehyde in 0.1 M sodium cacodylate buffer, pH 7.2 and postfixed...

Observation is a simple and reliable tool with the clinician. The level of tears, position of puncta, lids and eyelashes should be noted. Obstruction of the tear drainage system can be acquired or congenital, it is important to rule out acquired causes of tearing such as corneal, lid or lash abnormalities. Lacrimal obstruction problems can be divided as related to upper (puncta to lacrimal sac)...
