[The primitive gastric non- Hodgkin lymphoma].

THE PURPOSE: Of this work is to point out diagnostic problems together with the surgical indications in primitive gastric non-Hodgkin Lymphoma (LGNH). THE MATERIAL AND METHODS: Consist of 11 cases of LGNH (3.09% of 350 gastric cancers that underwent surgery between 1991-2000) of which 4 were women and 5 men, of an average 53 years of age. Three of the cases underwent surgery for various complications (HDS, perforation and pyloric stenosis) or for other clinical forms such as the pseudo-ulcerative one (4 cases) and the gastric carcinoma mimicking form (4 cases). Preoperative diagnosis was established by means of endobiopsy in 5 cases. SURGICAL TREATMENT: total gastrectomy (4 cases), inferior polar subtotal gastrectomy (5 cases) and 2/3 gastric resection (2 cases). RESULTS: Complications involving sub-phrenic abscess that triggered re-intervention in 2 cases; no immediately postoperative mortality. THE DISCUSSIONS AND CONCLUSIONS: Are enumerating the difficulties we encountered in diagnosing the cases and especially in the preoperative histologic diagnosis, the staging of the disease and setting the treatment with an emphasis on the surgical treatment. THE COMPLICATIONS: Induced by the disease, the diagnosis uncertainty and the early stages of the disease are as many eligible indications for the first linje surgical treatment in LGNH.
