Development of a gastrocutaneous fistula from a marginal ulcer after repair of duodenal injury with pyloric exclusion.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Duodenal trauma is rare but can be associated with significant morbidity and mortality (Pandey et al., 2011). Adjunct procedures, such as pyloric exclusion, can be performed to assist in surgical repair of these injuries. However, pyloric exclusion can lead to severe long-term complications associated with significant morbidity that can be difficult to repair. Case: A 35-year-old man with a history of duodenal trauma from a gunshot wound (GSW) status post pyloric exclusion and Roux-en-Y gastrojejunostomy presented to the Emergency Department (ED) with complaints of abdominal pain and leakage of food particles and fluid from an open wound around his surgical scar. Computed tomography (CT) scan on admission showed a tract extending from the gastrojejunostomy anastomosis to the skin representing a fistula. Esophago-gastro-duodenoscopy (EGD) reconfirmed a large marginal ulcer that had fistulized to the skin. After nutritional repletion, the patient was taken to the operating room (OR) for takedown of the enterocutaneous fistula and Roux-en-Y gastrojejunostomy, closure of gastrostomy and enterotomy, pyloroplasty and feeding jejunostomy tube placement. The patient was re-admitted after discharge with abdominal pain, vomiting and early satiety. EGD showed gastric outlet obstruction and severe pyloric stenosis which was managed with endoscopic balloon dilation. Conclusion: This case represents the severe and potentially life-threatening complications that may occur after pyloric exclusion with Roux-en-Y gastrojejunostomy. Gastrojejunostomies are prone to marginal ulceration which can perforate if not adequately treated. Free perforations cause peritonitis, but if the perforation is contained it can erode through the abdominal wall creating the rare complication of a gastrocutaneous fistula. Even after restoration of normal anatomy with a pyloroplasty, patients may suffer additional complications such as pyloric stenosis requiring continued intervention.
