Abstract
OBJECTIVE
The aim of this study was to describe the clinical characteristics and management of gastric outlet obstruction following acute pancreatitis(AP).
BACKGROUND
Gastric outlet obstruction (GOO) is not uncommon in acute pancreatitis (AP) and can occur throughout the course. However, the clinical features and related treatment of GOO is rarely reported.
METHODS
A retrospective review of AP patients with a diagnosis of GOO from March 2017 to June 2020 was performed. The diagnosis and management of GOO, as well as the demographic characteristics and clinical outcomes of the study patients, were collected and analyzed.
RESULTS
Over the three years, there were 60 AP patients developed GOO, constituting an incidence of 5.7%. Thirty-three patients (55.0%, 33/60) developed GOO in the first 4 weeks and 27 patients (45.0%, 27/60) after 4 weeks from onset. Pancreatic necrosis compression (60.6%; 20/33), gastric outlet gastrointestinal edema (27.3%, 9/33) are the main causes of early-onset GOO (≤4 weeks), while wall-off necrosis (92.6%, 25/27) is the leading cause in the late phase (>4 weeks). The management of GOO incorporates both supportive and specific treatment like gastric decompression, gastric juice reinfusion, percutaneous catheter drainage, etc. The mortality of AP patients with GOO (≤4 weeks) was 21.2% and none patients who developed GOO (>4 weeks) died.
CONCLUSIONS
GOO, as a gastrointestinal complication developed in AP patients, has two peak incidences in the duration of AP and needs to be paid more attention to.
