Intestinal lymphoma--a review of the management of emergency presentations to the general surgeon.

INTRODUCTION

Intestinal non-Hodgkin's lymphoma (NHL) is uncommon but not rare. This paper aims to review the recent evidence for the management of perforated NHL of the intestine, consider when chemotherapy should be commenced and examine the likely outcomes and prognosis for patients presenting as surgical emergencies with this condition.

METHODS

MEDLINE and Cochrane databases were searched using intestinal lymphoma, clinical presentation, perforation, management and prognosis. The full text of relevant articles was retrieved and reference lists checked for additional articles.

FINDINGS

Emergency surgery was required at disease presentation for between 11 and 64% of intestinal NHL cases. Perforation occurs in 1-25% of cases, and also occurs whilst on chemotherapy for NHL. Intestinal bleeding occurs in 2-22% of cases. Obstruction occurs more commonly in small bowel (5-39%) than large bowel NHL and intussusceptions occur in up to 46%. Prognosis is generally poor, especially for T cell lymphomas.

CONCLUSIONS

There is a lack of quality evidence for the elective and emergency treatment of NHL involving the small and large intestine. There is a lack of information regarding the impact an emergency presentation has on the timing of postoperative chemotherapy and overall prognosis. It is proposed that in order to develop evidence-based treatment protocols, there should be an intestinal NHL registry.
