RESUMEN
BACKGROUND: Caustic esophageal stricture length assessment is essential for planning endoscopic management and predicting its prognosis. We aimed to assess the accuracy of contrast swallow study (CSS) in measuring stricture length in comparison to endoscopy (definitive investigation for actual length measurement). METHOD: Medical records of caustic esophageal strictures between 2010 and 2020 were retrospectively reviewed. Reliability study was done to compare between radiological and endoscopic measurement of stricture length. RESULT: 124 CSSs for 91 patients were analyzed. Six studies showed no stricture, single stricture was reported in 101 studies, double strictures were reported in 16 studies, triple strictures were reported in one study (136 radiological stricture). Endoscopy revealed 133 true strictures. Number of the strictures was consistent between CSS and endoscopy in 112 studies (90.3%) and different in 12 studies (9.7%). Eight endoscopies revealed strictures not reported in CSS (5.5% false negative strictures), while 10 CSSs reported 11 strictures that were not detected during the endoscopy (7.6% false positive strictures). Reliability analysis revealed interclass correlation coefficientâ¯=â¯0.6 (95% CI 0.5 to 0.7) indicating moderate reliability. CONCLUSION: CSS is not accurate in assessing caustic esophageal stricture length. Combination of CSS and endoscopic investigation is better for proper evaluation of these patients. Level III of evidence.

PURPOSE: To report our initial experience with splenectomy and proximal spleno-left portal shunt as an alternative to the standard Rex shunt, when not applicable, in children with Extrahepatic Portal Vein Obstruction (EHPVO). METHODS: Patients from March 2015 till September 2018, with EHPVO not suitable for Rex shunt or whose caregivers refused to consent for Internal Jugular Vein (IJV) dissection were assessed and prepared for splenectomy with proximal spleno-left portal shunt. The operative technique includes splenectomy, freeing of the splenic vein from the pancreatic bed till its junction with the inferior mesenteric vein, and then anastomosis with the intrahepatic left portal vein at the Rex recess. A distal lieno-renal shunt was performed in one patient and was excluded from the study. RESULTS: A total of 14 patients (mean age: 4.6â¯years) underwent splenectomy with proximal spleno-left portal shunt during the study period. The mean operative time was 246â¯min, while the mean postoperative hospital stay was 4.1â¯days. The patients' follow up period ranged from 6 to 42â¯months (median: 19.6â¯months). Only two patients had a single attack of variceal bleeding, 2 and 2.5â¯months postoperative respectively, and required endoscopic management with no further bleeding episodes. While the rest of patients showed an improvement of their variceal grades after the surgery. CONCLUSION: Splenectomy with proximal spleno-left portal shunt seems to be a valuable alternative to the standard Rex shunt in treatment of children with EHPVO unsuitable for or following unsuccessful Rex shunt.
