Fixed rings and strictures in Eosinophilic Esophagitis develop due to continuing inflammation over time

Background and Aims: Two distinct e ndoscopic phenotypes of E osinophilic Esophagitis (EoE) h ave been identified: t he inflammatory (IP) a nd the stenosing (SP) p henotype. I t is not known whether these EoE-associated phenotypes are reflective of different phases during disease course. We aimed to assess the phenotype a t initial EoE p resentation and d iagnosis and to evaluate if SP increases over time. Methods: R etrospective a nalysis of t he Swiss EoE Database (SEED) extended b y a review of p atients charts, endoscopy and pathology records. Results: F orty-four E oE p atients were a nalyzed (33 males, mean age at index visit 41 ± 14 years, all Caucasians). Median follow-up t ime was 3.1 years (IQR 1-4, r ange 1 -18 years). Median diagnostic delay w as 5 y ears (IQR 2-16, range 0-34 years). A t first diagnosis, 3 2% ( 14/44) o f EoE patients h ad already presented w ith a stenosis. T he mean d iameter o f the stenoses w as 1 0 ± 2 mm, and the mean length was 2 .8 ± 2 .9 cm. Peak e osinophil count d id n ot c hange over t ime (48 ± 39 eos/HPF at index visit vs. 59 ± 41 eos/HPF at end of follow-up, n=44). The risk of the presence of a stenosis at index visit was 0% f or a d isease duration of 0 -4 y ears, 37% f or a d isease duration between 5-10 years and 67% f or a d isease duration >10 years (p = 0.0035, trend test). Conclusions: T he frequency of e sophageal stenoses i s proportional to the disease duration, whereas the inflammatory activity does n ot s ignificantly c hange over t ime. O ur f indings underscore the necessity to reduce diagnostic delay in EoE and to control the underlying inflammatory processes to prevent esophageal remodeling.

Esophageal and pharyngeal strictures: report on 1,862 endoscopic dilatations using the Savary-Gilliard technique

Treatment of symptomatic pharyngeal and esophageal strictures requires endoscopic dilatation. The Savary-Gilliard bougienage was developed by our department and has been used since 1980 for this purpose. We report our experience using this technique. The records of patients seen from January 1, 1963 to December 31, 2005, who had pharyngeal and esophageal strictures needing dilatation, were reviewed. The prevalence of different etiologies, and the incidence of complications using the Savary-Gilliard dilators were assessed. Efficiency of dilatation was assessed over a 17-year segment of this period, using number of dilatations and time intervals between dilatations until resolution of symptoms as outcome measures. Of the 2,652 pharyngeal and esophageal strictures reviewed, 90% were of organic origin (45% benign and 55% malignant stenoses), and 10% were of functional etiology. The most common etiologies were peptic strictures before the era of proton pump inhibitors, and postoperative anastomotic strictures thereafter. A total of 1,862 dilatations using the Savary-Gilliard technique were analyzed. Complication and mortality rates were 0.18 and 0.09% for benign and 4.58 and 0.81% for malignant etiologies, respectively. The number of dilatations per stricture and the time interval between different sessions were dependent on the type of strictures, varying from 1 to 23 dilatations and 7 days to 16 years, respectively. Pharyngeal and esophageal dilatations using the Savary-Gilliard technique were safe when used together with fluoroscopy. Overall, the efficiency of the dilatation procedure was good, but some types of strictures (e.g., caustic, post-surgical and/or post radiotherapy) were refractory to treatment and required repeated dilatations.

Bile duct stones, strictures and iatrogenic lesions: studies on early diagnosis and treatment.

Aims: This study was carried out to investigate the role of common liver function tests, and the degree of common bile duct dilatation in the differential diagnosis of extrahepatic cholestasis, as well as the occurrence, diagnosis and treatment of iatrogenic bile duct injuries. In bile duct injuries, special attention was paid to gender and severity distribution and long-term results. Patients and methods: All consecutive patients with diagnosed common bile duct stones or malignant strictures in ERCP between August 2000 and November 2003. Common liver function tests were measured in the morning before ERCP on all of these 212 patients, and their common bile duct diameter was measured from ERCP films. Between January 1995 and April 2002, 3736 laparoscopic cholecystectomies were performed and a total of 32 bile duct injuries were diagnosed. All pre-, per-, and postoperative data were collected retrospectively; and the patients were also interviewed by phone. Results: Plasma bilirubin proved to be the best discriminator between CBD stones and malignant strictures (p≤0.001 compared to other liver function tests and degree of common bile duct dilatation). The same effect was seen in Receiver Operating Characteristics curves (AUC 0.867). With a plasma bilirubin cut-off value of 145 μmol/l, four out of five patients could be classified correctly. The degree of common bile duct dilatation proved to be worthless in differential diagnostics. After laparoscopic cholecystectomy the total risk for bile duct injury was 0.86%, including cystic duct leaks. 86% of severe injuries and 88% of injuries requiring operative treatment were diagnosed in females. All the cystic duct leakages and 87% of the strictures were treated endoscopically. Good long-term results were seen in 84% of the whole study population. Conclusions: Plasma bilirubin is the most effective liver function test in differential diagnosis between CBD stones and malignant strictures. The only value of common bile duct dilatation is its ability to verify the presence of extrahepatic cholestasis. Female gender was associated with higher number of iatrogenic bile duct injuries, and in particular, most of the major complications occur in females. Most of the cystic duct leaks and common bile duct strictures can be treated endoscopically. The long-term results in our institution are at an internationally acceptable level.

A functional study of caustic strictures of the esophagus in children

The objective of the present study was to assess esophageal motor function in 21 children (7.5 ± 2.9 years) with caustic strictures. Esophageal manometry was performed using a water-infusion system interfaced with a polygraph and displayed on a computer screen. The data were compared with those obtained from 9 healthy children. Radionuclide transit was determined by studying deglutition of a single bolus of 99mTc pertechnetate in 10 ml of water. Non-peristaltic low-amplitude and long-duration waves were the most common findings detected in patients with strictures longer than 20% of esophageal length (N = 11). Compared with the control group, these patients presented lower mean amplitude and longer mean duration of waves (24.4 ± 11.2 vs 97.9 ± 23.7 mmHg, P < 0.05, and 6.7 ± 2.4 vs 1.6 ± 0.1 s, P < 0.05, respectively). Six patients presented low-amplitude waves just below the constricted site. Ten children presented delayed esophageal transit. There was an association between dysphagia and abnormalities on manometry (P = 0.02) and between symptoms and scintigraphy data (P = 0.01). Dysphagia in caustic strictures is due to esophageal motility abnormalities, which are closely related to the scarred segment.

Esophageal strictures in adult eosinophilic esophagitis: dilation is an effective and safe alternative after failure of topical corticosteroids

Strictures are a frequent complication of eosinophilic esophagitis. The efficacy and safety of topical corticosteroids and of dilation of eosinophilic esophagitis-associated strictures have not yet been thoroughly clarified. We present a retrospective analysis of 10 adult patients with eosinophilic esophagitis who had symptomatic esophageal stenosis that was unresponsive to topical corticosteroids, and who were treated using bougienage. Eight patients had one single stricture, one patient had two, and another had three strictures; mean stricture length was 2.1 cm (range 1 - 6 cm). Bougienage led to prompt symptom relief. Apart from transient postprocedural odynophagia, no severe complications occurred. During the follow-up (mean 6 months; range 2 - 11 months), all patients enjoyed sustained treatment response.

Ureteroileal Strictures After Urinary Diversion with an Ileal Segment—Is There a Place for Endourological Treatment at All?

Purpose We compared the long-term results of minimally invasive endourological intervention and open surgical revision in patients with a nonmalignant ureteroileal stricture. Materials and Methods We retrospectively evaluated the records of 74 patients (85 renal units) treated for unilateral or bilateral nonmalignant ureteroileal strictures. Overall, 96 endourological and 35 open surgical procedures were performed. Balloon dilatation and Acucise® or Ho:YAG laser endoureterotomy were used as minimally invasive endourological interventions. Open surgical revision with stricture resection and open ureteroileal end-to-side-reanastomosis was the alternate therapy. Treatment success was defined as radiological normalization or improvement of upper urinary tract morphology combined with absent flank pain, infection, ureteral stents or percutaneous nephrostomies. Results Median followup was 29 months (range 2 to 177). The overall success rate was 26% (25 of 96 cases) for endourological intervention vs 91% (32 of 35) for open surgical revision (p <0.001). Subgroup analysis showed a significant difference in the success rate of minimally invasive endourological interventions vs open surgical revision for strictures greater than 1 cm (3 of 52 cases or 6% vs 19 of 22 or 86%, p <0.001). The success rate of endourological and open surgical procedures for strictures 1 cm or less was 50% (22 of 44 cases) and 100% (13 of 13), respectively. After adjusting for multiple preoperative stricture characteristics, only stricture length was strongly and inversely associated with a successful outcome (p <0.001). Conclusions Open surgical revision produces better results than minimally invasive endourological intervention for ureteroileal strictures, particularly those greater than 1 cm. The success rate of endourological intervention is acceptable only for ureteroileal strictures 1 cm or less. Therefore, ureteroileal strictures greater than 1 cm should be primarily managed by open surgical revision.
