What treatment is indicated for gastric outlet obstruction due to MALT lymphoma?

The treatment indicated for gastric outlet obstruction due to MALT lymphoma is surgical resection. Mucosa-associated lymphoid tissue (MALT) lymphoma is a type of non-Hodgkin lymphoma that can arise in the stomach, often related to chronic Helicobacter pylori infection. When it leads to gastric outlet obstruction, the blocked area can cause significant symptoms, including persistent vomiting and inability to eat.

Surgical resection is the appropriate intervention because it directly addresses the obstructed area, potentially providing symptomatic relief and removing the neoplastic tissue. In cases where MALT lymphoma is localized and causing obstruction, resection can be both diagnostic and therapeutic, allowing for a definitive treatment of the lymphoma and resolution of the obstructive symptoms.

While chemotherapy and radiation may be indicated for MALT lymphoma treatment depending on the stage and presence of disease, they are not typically first-line options for managing acute gastric outlet obstruction caused by this type of lymphoma. Similarly, endoscopic dilatation is generally considered for non-malignant strictures and may not effectively treat the underlying lymphoma. Finally, not providing any treatment in the face of obstructive symptoms would lead to significant morbidity and is not a viable management strategy.
