Ulcerous jejuno-ileitis with symptomatic sprue

Fatal course of idiopathic chronic ulcerative enteritis with panenteritis and perforation: a case report and review of literature

Background

Idiopathic chronic ulcerative enteritis (ICUE) is a very rare disease with high mortality. Because of clinical rarity, several small case reports have been published and there is a lack of large sample study. Preoperative definite diagnosis is difficult. Although definite treatment for ICUE is radical surgical resection, surgical decision in operative field is difficult.

Case presentation

A 77-year-old man came to the emergency department with complaints of a 1-day history of abdominal pain and abdominal distension. Abdominal computed tomography revealed ileus and focal free air. Laparotomy revealed multiple small bowel tiny perforations in the ileum. The serosa surface in the whole small bowel had small multiple yellowish tiny discolored lesions. Despite the presence of multiple mucosal ulcers in entire small bowel, the ileum including perforation site was resected segmentally. Microscopically, mucosal ulcers in resected small bowel demonstrated transmural inflammation, no granuloma, and no lymphoid aggregates. These features were consistent with a diagnosis of ICUE with panenteritis and perforation. After surgery, the patient’s general condition gradually aggravated. Unfortunately, the patient died of multiple organ failure on post-operative day 14.

Conclusion

Surgically, the decision including resection range, anastomosis or enterotomy becomes difficult in ICUE with panenteritis. According to recent 40 year’s revised data, the post-operative mortality of ICUE is about 53.4%. Although ICUE is rare, its recognition is important for appropriate diagnosis and treatment. Retrospective multicenter case studies are required to determine proper treatment and improve prognosis.

Idiopathic chronic ulcerative enteritis with perforation and recurrent bleeding: A case report

Idiopathic chronic ulcerative enteritis (ICUE) is a distinct entity without a defined etiology and is rarely seen in the clinic. Patients with ICUE mainly present with insidious abdominal symptoms such as chronic abdominal pain and intermittent gastrointestinal hemorrhage and symptoms of malnourishment in the early stages of the disease. ICUE is always difficult to diagnose. However, as the disease progresses, patients have a variety of acute abdominal complications such as hemorrhage, perforation, or ileus. Surgical intervention is always needed, and the condition can recur and require repeat laparotomy. When diffuse ulceration of the small bowel is present in the absence of recognizable causes, it is classified as nonspecific or idiopathic. The histological examination always demonstrates an acute, chronic inflammatory infiltration without giant cells, granulomas, or villous atrophy. The etiology of ICUE has not been identified, and its pathogenesis is poorly understood; therefore, radical surgical resection is considered the best available treatment. Here, we report a case of ICUE characterized by nonspecific, multiple, small intestinal ulcers resulting in perforation and recurrent bleeding. The differential diagnosis and the treatment are also discussed.

Coeliac disease and (extra)intestinal T-cell lymphomas: definition, diagnosis and treatment

Intestinal lymphomas encompass those lymphomas with a dominant or only localized occurrence in the intestinal tract. Coeliac disease is highly associated with enteropathy-associated T-cell lymphomas (EATLs). Coeliac disease-related lymphomas can appear at nodal or extranodal sites. EATL is often multifocal with ulcerative lesions, which explains the high perforation rate at presentation or during chemotherapy. Staging includes ear-nose-throat examination and CT scan of the chest and abdomen. Positron emission tomography (PET) scanning may be valuable. Accurate diagnosis based on endoscopic biopsies is preferable; if necessary, full thickness laparoscopic small-bowel biopsies are mandatory. Refractory coeliac disease (RCD) with aberrant T cells carries a high risk of development of EATLs. There is no satisfactory treatment for EATL, the only possibility of preventing EATL development in RCD being autologous bone marrow transplantation. EATLs can present in 20% of patients as extra-small-bowel T-cell lymphomas; such as subcutaneous panniculitis-like lymphoma, hepatosplenic gamma/delta lymphoma, nodal as well as sinus, gastric or colon disease and extraintestinal T-cell lymphomas. The majority of EATLs present as large cell lymphoma CD3+, CD8-, CD30+; however, they also present as small cell lymphoma CD3+, CD8+, CD30-. Sometimes gamma/delta lymphomas in CD are recognized. Work-up of EATL must include immunohistology, T-cell flow cytometry, T-cell rearrangement and adequate imaging with CT and PET scanning.

The major complications of coeliac disease

Neoplasms constitute the major complication of coeliac disease, and high-grade T-cell lymphoma of the small intestine (enteropathy-associated T-cell lymphoma) is the most common neoplasm in this category. HLA genotyping indicates that in patients with enteropathy-associated T-cell lymphoma have the coeliac disease associated DQA1*0501, DQB1*0201 phenotype, although additional HLA-DR/DQ alleles may represent risk factors for lymphoma development. Molecular biological and immunohistochemical studies have shown that the intestinal mucosa distant from the tumour contains clonal populations of small T cells, often of the same clone as the high-grade T-cell lymphoma. These findings suggest that enteropathy-associated T-cell lymphoma arises in the setting of coeliac disease and evolves from reactive intraepithelial lymphocytes through a low-grade lymphocytic neoplasm to a high-grade tumour, which is usually the cause of the presenting symptoms. Most cases of chronic ulcerative enteropathy (ulcerative jejunitis) are probably part of the same disease process. If the ulceration occurs at a time when the neoplastic T-cells are of a low grade, morphological recognition of tumour cells in the ulcers may be impossible. Carcinoma of the pharynx and oesophagus, and adenocarcinoma of the small intestine, are increased in frequency in patients with coeliac disease. The increased risk of carcinoma of the oesophagus may be related to vitamin A deficiency. A number of reports have indicated an increased prevalence of various types of chronic hepatitis in patients with coeliac disease, but no coherent view of the cause of this association has emerged. Similarly, patients with coeliac disease have been reported to have various forms of fibrosing lung disease of uncertain causation. In recent years, there have been several reports, mainly from Italy, of a syndrome of epilepsy and bilateral brain calcification occurring in coeliac patients. The pathogenesis of this condition is not known and its prevalence in other communities is uncertain. Splenic atrophy occurs frequently in patients with coeliac disease and is related to the severity of the disease and degree of dietary control. Splenic atrophy predisposes to infection with capsulated bacteria, although mortality studies indicate that infection with these organisms is not a major cause of death in patients with coeliac disease.

Radiology in Idiopathic chronic ulcerative enteritis

Two patients with idiopathic chronic ulcerative enteritis (ICUE) having malabsorption, subtotal villous atrophy and non-specific small intestinal ulceration are presented with emphasis on the radiological features. No improvement was shown morphologically following gluten withdrawal. The literature on this condition is reviewed. Obstruction, perforation and melaena are serious complications and the prognosis is poor; only 11 out of 31 reported cases survived. Differentiation from coeliac disease, Crohn's disease and primary intestinal lymphoma is discussed.

Celiac disease complicated by chronic nongranulomatous ulcerative enterocolitis, nodular lymphoid hyperplasia, and disseminated intravascular coagulation

A patient is presented in whom celiac disease was complicated by the development of chronic nongranulomatous ulcers in the small and large intestine. In addition, he had nodular lymphoid hyperplasia in the bowel wall and mesenteric lymphoadenopathy. The terminal illness was characterized by disseminated intravascular coagulation. It is postulated that the lymphoid hyperplasia was secondary to excessive stimulation of the reticuloendothelial system by nongluten antigens and may be a precursor of the development of lymphoma in celiac disease. Nongluten antigens such as bacteria or endotoxins were probably responsible for the consumptive coagulopathy.

Chronic non-specific ulcerative duodenojejunoileitis: report of four cases

Four patients with chronic non-specific ulcerative duodenojejunoileitis (CNSUDJI) are reported. The clinical picture included abdominal pain, fever, and a malabsorption syndrome. Main rediological findings were diffuse narrowing of the jejunal loops with total effacement of the mucosal folds. Multiple peroral biopsies of the small intestine showed various degrees of mucosal abnormalities from total villous atrophy to normal villi, but ulcerations were diagnosed only by operative full thickness biopsies or resection of the small bowel. The ulcerative process was associated with well-documented coeliac disease in two patients: in one of them it occurred as a fatal complication involving also the colon, three years after the start of a gluten free diet, while the disease was in full clinical and histological remission. In the other case, coeliac disease was revealed by obstructive symptoms due to stenosing ulcerations; five months after surgical resection of the stenosis, institution of a gluten free diet induced a dramatic improvement. In the two other patients ulcerations were not associated with coeliac disease: one of them had a patchy villous atrophy and resisted a gluten free diet and total parenteral nutrition; she was improved by and dependent upon steroids but finally died. The last patient had normal villous height; ulcerations were located exclusively along the mesenteric border of the small bowel; he had a low-grade protracted evolution resisting any form of therapy and developed a peripheral neuropathy of unknown aetiology. On the basis of our cases and of a review of the literature the discussion focuses on the difficulty in diagnosing CNSUDJI, its relationship with coeliac disease, and its management and prognosis.
