True Incidence

Bronchial webs are thin, membrane-like diaphragms that may obstruct the airway. Several congenital cases have been reported. Though rare, the true incidence of these lesions is probably underestimated because many of them are unrecognized. The case of a 71-year-old woman with an acquired bronchial web causing right main stem bronchus obstruction that went unrecognized for 47 years post-trauma is reported. The lesion was successfully treated using rigid bronchoscopy with laser therapy, balloon dilation and stent placement. This is the first reported case of an acquired bronchial web formation. It is also the first reported case that was successfully treated with this technique.

AbstractThe traditional morbidity and mortality associated with traditional management has stimulated exploration of endoscopic approaches. Success depends on patient selection, the location and etiology of obstruction, patient status, and the capability of the endoscopist. This article discusses techniques of intralumenal dilation and stent placement and results from systematic reviews.

Large Balloon Dilation

Biliary stones represent the most common indication for therapeutic endoscopic retrograde cholangiopancreatography. Many cases are successfully managed with biliary sphincterotomy and stone extraction with balloon or basket catheters. However, more complex conditions secondary to the specific features of stones, the biliary tract, or patient’s needs could make the stone extraction with the standard techniques difficult. Traditionally, mechanical lithotripsy with baskets has been reported as a safe and effective technique to achieve stone clearance. More recently, the increasing use of endoscopic papillary large balloon dilation and the diffusion of single-operator cholangioscopy with laser or electrohydraulic lithotripsy have brought new, safe, and effective therapeutic possibilities to the management of such challenging cases. We here summarize the available evidence about the endoscopic management of difficult common bile duct stones and discuss current indications of different lithotripsy techniques.

Central Airway

Absorption of airway liquid, as it moves from the large surface area of distal airways to more central airway surfaces, is considered to be essential for regulation of the depth of airway liquid. The short-circuited excised canine trachea, however, secretes Cl- and absorbs a lesser amount of Na+. We compared bioelectric properties and unidirectional ion flows across epithelia excised from trachea and mainstem and 4th- to 6th-generation bronchi. Compared with trachea, 4th- to 6th-generation bronchi exhibited a lower potential difference (8.9 compared with 35 mV) and higher direct-current conductance (6.9 compared with 2.1 mS . cm-2). Corresponding values for main-stem bronchus were intermediate. Under short-circuit conditions, the trachea secreted Cl- (1.75 mueq . cm-2 . h-1) and absorbed Na+ (1.15 mueq . cm-2 . h-1). K+ fluxes were symmetric. Main-stem bronchus exhibited a similar pattern of ion flow. Subsegmental bronchi absorbed 2.0 mueq Na+ . cm-2 . h-1 and secreted 0.04 mueq K+ . cm-2 . h-1, but net Cl- transport was absent. Under open circuit, Na+ absorption persisted in all regions, but net Cl- secretion disappeared in the trachea and main-stem bronchi. Na+ absorption was uniformly abolished by addition of ouabain (3 x 10(-5) M) to the submucosal bath. We conclude that NaCl absorption dominates resting ion translocation in canine bronchi and that liquid absorption probably occurs at these sites in vivo.

Abstract Background and study aims Endoscopic retrograde cholangiopancreatography (ERCP) is often performed in patients with primary sclerosing cholangitis (PSC). Our aim was to validate a treatment approach with the objective of decreasing ERCP related adverse events (AEs). Patients and methods All patients who had undergone ERCP for PSC during the period from 2002 – 2012 were identified (group I). This group had traditional ERCP (no bile aspiration prior to contrast injection with balloon dilation and stent placement for treatment of dominant strictures). To decrease ERCP-related AEs, we changed the ERCP approach in which bile aspiration was performed prior to contrast injection and balloon dilation alone was performed for treatment of dominant strictures. This was tested prospectively in all patients undergoing ERCP for PSC from 2012 – 2014 (group II). Results The risk of overall AEs and cholangitis was relatively less in group II compared with group I [(2.1 % vs. 10.3 %; P = .38) and (0 % vs. 4.4 %; P = .68)]. On bivariate analysis, change in ERCP approach was associated with decreased risk of post-procedure cholangitis (0 % vs. 10.2 %, P = .03) and overall AE (0 % vs. 18.6 %, P = .03). There were no AEs in 22/46 patients in group II who had bile aspiration with balloon dilation. On multivariate analysis, only biliary stent placement was associated with increased risk of AEs (OR 4.10 (1.32 – 12.71); P = .02) and cholangitis (OR 5.43, 1.38 – 21.38; P = .02) respectively. Conclusion Biliary aspiration and avoidance of stenting approach after dilation of strictures during ERCP in PSC patients appears to be associated with decreased risk of cholangitis and overall AEs. Future prospective randomized controlled trials are needed to validate our observation.
