Objectives: The aim of this study was to investigate the efficacy and safety of endoscopic local infiltration of mitomycin C (MMC) after oesophageal dilation for children suffering from refractory postcorrosive oesophageal stricture (OS). Methods: Children referred to Cairo University Specialized Paediatric Hospital with refractory postcorrosive OS during the period from March 2016 to August 2017 were included in this study. MMC was infiltrated endoscopically at the stricture site by the end of the dilation session. The measured outcomes were dysphagia score (DS) and periodic dilation index (PDI). Results: During the inclusion period of the presented study, 17 children met the inclusion criteria. There were 7 boys and 10 girls. During the follow-up period, an average of 3.8 dilation sessions with MMC infiltration per case were performed, using a total dose of 1 mg each session. The median follow-up period was 9.5 months. The median DS improved from DS 3 before application of MMC to DS 0 at the last follow-up (P < 0.001). Additionally, the median PDI declined from 1 to 0.75 after MMC application (P = 0.052). Sixteen cases (94%) became dysphagia free after 6 months. Seven patients experienced postdilation minor bleeding that was spontaneously resolved, not triggering blood transfusion. There were no infiltration-related complications in the included series. Conclusion: Stricture-site MMC endoscopic infiltration by the end of a dilation session proved to be safe and effective in improving the DS and PDI.

Background: High jejunal atresia is associated with significant dilatation of the proximal segment. This poses two problems: (a) calibre discrepancy with the distal unused segment and (b) hypomotility causing stasis. Tapering jejunoplasty/enteroplasty could offer a practical solution in selected cases, leading to early establishment of feeds. This work aims to evaluate the outcome of tapering jejunoplasty including its effect on establishing enteral feeding in neonates with proximal jejunal atresia. Results: Twenty-two neonates with jejunal atresia (types I, II and IIIa) were reviewed. Cases with multiple atresia, apple-peel variant and meconium ileus were excluded. The included cases fell retrospectively into two groups: group A (13 cases)-very proximal atresia and significant dilatation and group B (9 cases)-mid/distal jejunal atresia. For group A, we excised only the distal tip of the dilated bowel and stripped a seromuscular triangle up to the duodenojejunal flexure and inverted the mucosa along the antimesenteric border, followed by an end-to-oblique anastomosis. For group B, we performed a standard excision of a short proximal segment and an end-to-oblique anastomosis. There was no significant difference in the gestation age or birth weight between both groups. The mean operative time was 90 min for group A and 60 min for group B. The duration until full enteral feeds became tolerated, and parenteral nutrition was weaned accordingly was shorter in group A (mean 10.8 days) as compared to group B (mean 14.5 days), p = 0.045. Conclusion: Tapering jejunoplasty by seromuscular stripping and mucosal inversion facilitates early establishment of feeds in proximal jejunal atresia.
