Delayed gastric emptying after Roux-en-Y due to four types of partial obstruction

Area of Science:

• Gastroenterology
• Surgical Procedures

Background:

• Delayed gastric emptying can occur after Roux-en-Y gastrojejunostomy.
• Identifying the cause is crucial for effective treatment.

Purpose of the Study:

• To investigate the causes of delayed gastric emptying in patients following Roux-en-Y gastrojejunostomy.
• To evaluate diagnostic methods and treatment outcomes.

Main Methods:

• Retrospective review of 42 patients with delayed gastric emptying post-Roux-en-Y gastrojejunostomy.
• Utilized upper gastrointestinal (GI) series, nuclear gastric emptying studies, and upper GI endoscopy.
• Diagnostic modalities included surgical correction and endoscopic manipulation for treatment.

Main Results:

• Partial obstruction was identified as the sole cause of delayed gastric emptying in 12 patients.
• Four types of partial obstruction were classified: kinked loop, high anastomosis, marginal ulcer, and pouchlike deformity.
• Upper GI endoscopy accurately diagnosed the obstruction site and nature.
• Surgical correction (4 patients) and endoscopic relief (6 patients) resolved symptoms in all cases.

Conclusions:

• Partial obstruction is the definitive cause of delayed gastric emptying after Roux-en-Y gastrojejunostomy in this series.
• Upper GI endoscopy is highly effective in diagnosing the cause and location of obstruction.
• Conservative and surgical interventions provide successful symptom relief without necessitating extensive gastrectomy.
