Pyloric stricture after corrosive ingestion in children: an attempt to address the optimum management of this rarity

Corrosive ingestion in pediatric population can have devastating consequences. Pyloric stricture which is a rarer complication has not been discussed in details in existing literature. Whereas the presentation is more or less similar, a “case specific” approach may be required for the best outcome. We analyzed our series of eight patients to formulate a suitable approach to its management. This was a prospective observational study in the department of Pediatric Surgery in a tertiary health care centre in central India. Eight (n=8) patients with corrosive injuries exclusive to the pyloric antrum were analyzed with respect to the corrosive ingested, symptomatology, nutritional status, investigation findings, surgery undertaken and follow up. Total number of patients in our study were eight. Male -7 and female-1, mean age of 6.8 years, ranging from 4 and 10 years, most common agent was acid, ingested accidentally. Period of development of gastric outlet obstruction was 23 days, range between 11 days and 33 days. Initially presented with odynophagia but later developed features of gastric outlet obstruction. Procedure performed were Heineke Mickulicz pyloroplasty and Billroth I gastroduodenostomy with FJ depending on the intra operative findings. No significant post operative complications were encountered on follow up, all the patients had improved general condition and gained adequate weight. No re do surgeries were performed. Corrosive injury of the UGI tract is not uncommon in children. Pyloric stricture as a complication is relatively rare. Parents may seek consultation late only after the child has lost reasonable amount of weight. UGI Endoscopy and UGI contrast study are indispensable to evaluate the severity of damage and formulate the optimum plan of surgery. Early surgical intervention gives excellent result. Both Pyloroplasty and Billroth I anastomosis are safe with low morbidity and excellent long term outcome.

The safety and efficacy of the trans-umbilical approach for pyloroplasty in the management of post-acid corrosive gastric outlet obstruction in children

Background Gastric outlet obstruction (GOO) may follow acid corrosive ingestion. Several surgical techniques have been reported after the failure of endoscopic dilatation. The aim of this study was to evaluate the feasibility and safety of Heinecke-Mikulicz pyloroplasty (HMP) through a circum-umbilical skin incision in children with pyloric stricture after accidental acid corrosive ingestion. Results Seven patients were males and 4 were females, their ages ranged from 17 months to 6 years at the time of definitive treatment. The surgery was completed successfully in all patients through the circum-umbilical incision. Vertical extension of skin incision was needed in one patient. The pylorus was grossly affected in 9 patients. Both pylorus and gastric antrum were involved in 2 patients. Nine patients had an excellent postoperative course with the cessation of vomiting and progressive weight gain. One patient developed postoperative recurrent stricture treated by gastrojejunostomy. Another patient with associated esophageal stricture responded to repeated endoscopic dilatation for the esophageal stricture and pyloroplasty for the pyloric stricture. No surgical site infection or wound dehiscence occurred in any patient. Conclusion Heinecke-Mikulicz pyloroplasty through a circum-umbilical approach is both feasible and safe in the majority of children with post-acid corrosive GOO. It is associated with satisfactory wound healing and excellent cosmetic outcome. Different techniques are recommended in cases of severe pyloric stricture associated with significant proximal gastric antral scarring.

Heineke-Mikulicz pyloroplasty for isolated pyloric stricture caused by corrosive ingestion in children

Corrosive ingestion in children is a common problem in low income countries. These agents cause injuries and later strictures of esophagus and stomach. Gastric outlet obstruction is known complication of acids and surgery is the mainstay of treatment. There are multitude of surgical options for these strictures depending on the involved segment of the stomach and experience of the surgeon. Here we present three cases of children who accidentally ingested acid stored in soda bottles and subsequently developed isolated pyloric strictures. These cases presented between August 2018 and April 2019 to our facility, a tertiary care hospital in Karachi, Pakistan. All three patients had an initial latent period of one to two weeks following corrosive ingestion, after which symptoms of gastric outlet obstruction appeared. Intraoperatively, all three had normal esophagus and antrum but scarred and strictured pylorus. Heineke-Mikulicz pyloroplasty was done in these cases without complications and the outcomes were satisfactory. doi: https://doi.org/10.12669/pjms.36.ICON-Suppl.1714 How to cite this:Soomro MA, Aftab M, Hasan M, Arbab H.
