An unusual case of lymphoma is presented in which small bowel intussusception due to a lymphomatous nodule caused an acute abdomen, requiring small bowel resection. Four weeks later a second intussusception caused intestinal obstruction, necessitating a second laparotomy and bowel resection. The high incidence of malignant tumor in adult cases leads us to recommend primary resection without manual reduction in all but rectosigmoid and selected small bowel cases.

Twenty-seven cases of primary peripheral T-cell lymphomas of the intestine (PTLI) were investigated. Seven patients had histories of malabsorption. The most frequent symptoms at presentation were weight loss, abdominal pain, and acute abdomen. The jejunum was the most common site of lymphoma and multifocal disease was found in 72% of the cases. Twenty-two patients (92%) presented with localized disease confined to the intestine and abdominal lymph nodes, only two patients had generalized disease. According to the pattern of lymphoma infiltration and the morphology of the uninvolved small intestinal mucosa, 21 cases were separated histologically into three categories; 1) enteropathy-associated T-cell lymphoma (EATCL, n = 9) showing predominant intramucosal lymphoma spread and villous atrophy of uninvolved mucosa with high density of intraepithelial lymphocytes (IEL), 2) EATCL-like lymphoma without enteropathy (EATCL-LLWE, n = 5) but with an infiltration pattern similar to EATCL, and 3) T-cell lymphoma without features of EATCL (Non-EATCL, n = 7). Distinctive features of EATCL were the high incidence of malabsorption states, multifocal intestinal disease in all cases, and the high frequency of intestinal recurrences. On frozen sections four of eight PTLI showed the phenotype CD3+ CD4- CD8- HML-1+, which is also expressed on a small subset of normal IEL. The morphologic and immunomorphologic findings suggest that the majority of PTLI is derived from mucosal T lymphocytes. This derivation may be responsible for certain biologic features, such as the preferential spread to and relapse of PTLI at small intestinal sites.

The records of 101 patients with primary small intestinal malignant tumor at NTUH, collected from 1960 to 1989, were reviewed. These patients represented 1.2% of the patients with gastrointestinal cancer at NTUH over the same period. Fourty-two (41.6%) of the cancer patients had lymphomas, 30(29.7%) had adenocarcinomas, 26 (25.7%) had leiomyosarcomas, and 3(3.0%) had carcinoid tumors. The average age at cancer presentation was 47.5 years (range from 3 to 96). The lymphoma patients had an average age of 35.1 years, while adenocarcinoma patients averaged 60.4 years of age. Leiomyosarcoma and carcinoid tumors averaged 51.2 years and 59 years, respectively. There were 65 male patients and 36 female patients, and there was a male predominance in all groups except for the leiomyosarcoma group which had an equal sex ratio. Generally speaking, the incidence rate for the areas involved were similar in the duodenum, jejunum and ileum. However, adenocarcinomas were more common in the duodenum (53%) and 45% of lymphomas were found in the ileum, as were the carcinoid tumors (66%). The most common presenting symptom was abdominal pain (62%), with bleeding second (32%). Obstruction and palpable mass together were present in 29% of the cases. Body weight loss was found in 25% of patients, and 14% of the patients presented with acute abdomen due to intestinal perforation. Laparotomy was the most common diagnostic procedure (60%). Preoperative diagnoses were possible in cases of duodenal and upper intestinal malignancies, but were rarely possible in patients with lower intestinal malignancies. Sixty-eight patients (68%) underwent tumor resection for palliation or cure. The operation mortality was 4%.(ABSTRACT TRUNCATED AT 250 WORDS)

Forty-two patients with non-Hodgkin's malignant lymphoma (NHML) of the gastrointestinal tract were operated on between 1971 and 1989. NHML was located in the stomach in 23 (55%), in the small bowel in 16 (38%), and in the colon in 3 (7%). One-fourth of patients were hospitalized with an acute abdomen and had to undergo emergency surgery. Preoperative diagnosis was obtained in 40% of cases only. Since 1986, however, and thanks to immunohistochemistry, gastroscopy was able to diagnose gastric NHML in 10 of 11 cases. Twenty-six patients (62%) underwent curative surgery. Operative mortality was 11.9%, 42% in case of emergency surgery, but mortality was nil after elective procedures. Half the patients had no further treatment. Five-year survival was 67%. Except for the mucosa associated lymphoid tissue (MALT) tumors, histopathological characteristics had less influence on prognosis than expected. On the other hand, prognosis was significantly better after curative surgery (p less than 0.001).

Eight cases of abdominal tuberculosis from the Department of Medicine, Singapore General Hospital are reported to illustrate the varied clinical manifestations of the disease. Presentation ranged from asymptomatic hepatomegaly to acute abdomen (intestinal obstruction/perforation). Chronic non-specific symptomatology (fever, weight loss, abdominal pain, diarrhoea, jaundice) was commonest. There were three patients with hepatic tuberculosis, two with tuberculous mesenteric lymphadenitis and three with intestinal tuberculosis, two of whom had concomitant tuberculous peritonitis. Only three patients had coexisting pulmonary tuberculosis. The diagnosis was unsuspected at presentation in four patients. Initial provisional diagnoses included typhoid, abdominal lymphoma, hepatic malignancy, chronic hepatitis and iatrogenic gut perforation. All patients responded totally to conventional antituberculous therapy.

During a 5-year period, 15 cases of primary gastrointestinal lymphoma, corresponding to 14% of the non-Hodgkin's lymphomas, were diagnosed in a population of 200,000. Most patients had a short duration of symptoms--less than 3 months--and a clinical picture dominated by abdominal pain. All patients were laparotomized and six patients presented with an acute abdomen and were subjected to emergency operations. In seven cases, gastrointestinal malignancy was not suspected preoperatively. The patients were treated with a combination of surgery, cytostatic therapy, and/or radiotherapy. Cases with localized disease had a favorable prognosis, seven of nine patients being alive 31 to 70 months after diagnosis. A statistically significant difference in median survival was also noted between patients with lymphomas of low-grade and high-grade malignancy (70+ vs. 10.5 months).

Peritoneoscopy is a simple and effective means of diagnosing or excluding intra-abdominal disease. It is currently underutilized and merits increased recognition particularly by general surgeons. The first 77 peritoneoscopic examinations performed by a general surgeon in a large hospital associated with a cancer agency are reviewed. An exact diagnosis was made in 78% of 58 patients in whom the primary diagnosis was in doubt and in 93% of that group management was influenced. Surgical exploration of the abdomen was avoided in 29 patients. The major indications for using the method were: to search for metastases, to evaluate the acute abdomen and to stage lymphoma. Local anesthesia and nitrous oxide insufflation were used almost exclusively. Biopsy was performed in 36 patients and there was one death directly attributable to liver biopsy. In two patients peritoneoscopy was unsuccessful.

A 39 year old man had been suffering from chronic bowel symptoms of changing intensity. At the age of 37 the diagnosis of nontropical sprue was made. After institution of a gluten free diet the patient improved, but soon diarrhea started again. In the examination of peripheral blood smear, bone marrow and small intestinal mucosal biopsies a dominant eosinophilia was found. Since several attacks of abdominal colics and finally an acute abdomen occurred, a laparotomy was indicated. This operative intervention showed a perforation of the intestine and tumors in the bowel wall as well as numerous lymphomas spread over the whole mesentery. The histological examination of both the small intestine resect and the lymphomas proved the diagnosis of a highly malignant Non Hodgkin lymphoma (middle and large cell pleomorphic T-cell lymphoma with transition into a large cell anaplastic lymphoma [ki-1 lymphoma]). The patient received a chemotherapy with COEP but died 4 weeks after the surgery.

The clinical course of patients with hematological disease, especially after treatment, is often complicated by gastrointestinal infections. Between 1986 and 1990 a total of 18 patients affected with hematologic disease and presenting with an acute abdomen were admitted to the surgery department at the University of Rome "La Sapienza". Most patients were affected with acute or chronic myeloid leukemia (61%) and lymphoma. Five patients with acute appendicitis, three with necrotizing enterocolitis, three with spontaneous hemoperitoneum, three with cholecystitis, two splenic infarctions and two intestinal occlusions were diagnosed. Symptoms were often vague and non specific and blood counts revealed neutropenia in all but two patients, while anemia was characteristic in spontaneous hemoperitoneum and in neutropenic enterocolitis. Fungemia occurred in only two cases while bacteremia was present in seven. The most critical patients were those affected by neutropenic enterocolitis and acute cholecystitis. Sonography was meaningful in the diagnosis of hemoperitoneum, splenic infarct and acute cholecystitis. All patients underwent surgical procedures within 48 hours of admission to the department. In all cases peritoneal washing was performed and at least one peritoneal drainage was left. In all cases of necrotizing enterocolitis, intestinal resections, either ileal or colonic, were followed by an immediate anastomosis in two layers. Intensive hematological and antibiotic post surgical care was performed in all patients. Seven patients presented minor complications (38.8%), and only one died (5.5%). Emergency surgical treatment may be safely carried out in patients with hematological diseases presenting with an acute abdomen. Intensive postsurgical care is mandatory for the recovery of patients and the patient's critical condition should not be a deterrent to surgical intervention.

Computed tomography (CT) is playing an increasingly greater role as the initial diagnostic imaging modality for acute abdomen. Abdominal pain is the most common presenting complaint for intestinal lymphoma, and acute abdomen is a not infrequent admitting complaint. We present the CT findings of five patients with intestinal lymphoma whose initial complaint was acute abdomen. Of these five patients, four had an identifiable mass that was located in the right lower quadrant, with the fifth patient having no identifiable mass on CT. The average mass size was 7.8 cm. Three of the patients showed involvement of the colon only, and two showed involvement of the small bowel only, with acute abdomen in only one of the patients with small-bowel involvement being due to direct extension from mesenteric lymph nodes. Pneumoperitoneum and free intraperitoneal fluid were seen in two patients. It is important, therefore, that the radiologist be aware that one of the causes of acute abdomen with primary bowel involvement is lymphoma, which can simulate appendicitis or diverticulitis in its presentation clinically and by physical examination.
