Follicular Lymphomas

Follicular lymphomas occur rarely in the gastrointestinal tract, representing only 1–3% of all gastrointestinal tract B-cell non-Hodgkin lymphomas. We describe endoscopic analysis of 3 cases of follicular lymphoma in the small intestine using double-balloon endoscopy. Double-balloon endoscopy revealed multiple nodular lesions and elevated white patches, multiple polypoid lesions, and scattered white polypoid and nodular lesions in the duodenum and small intestine. Fuji Intelligent Chromo Endoscopy demonstrated small, whitish nodules, and narrow-band imaging showed a coiled, elongated vascular pattern within the elevated lesions. These cases are the first follicular lymphomas in the small intestine evaluated using narrow-band imaging or Fuji Intelligent Chromo Endoscopy to be reported.

Background. The small intestine has been considered to be a highly difficult organ to visualize in imaging examinations due to its anatomical location compared with the stomach and the colon. In recent years, many imaging modalities have become available, such as CT enterography, MR enterography, capsule endoscopy (CE), and double-balloon endoscopy (DBE).Patients and Methods. DBE was performed in the postoperative intestines of 91 patients (128 DBE examinations) at Iwate Medical University between 2004 and 2010. There were 61 male and 30 female patients, and their mean age was 69.7 years (range: 30–80 years).Results. A total of 124 DBE examinations were performed with endoscope insertion into the reconstructed intestines. The endoscope reached the blind end in 115 of 124 examinations, (92.7%). There were 17 patients with obscure gastrointestinal bleeding in whom 30 DBE examinations were performed. The bleeding site was identified in 12 patients (70.6%). Nine patients underwent endoscopic treatment. Hemostasis was achieved in all patients.Conclusion. DBE is very useful modality for the assessment and application of endotherapy to areas of the small bowel which have been altered by surgery.

A 70-year-old woman presented with follicular lymphoma involving the stomach, duodenum, jejunum, bone, and lymph nodes. Esophagogastroduodenoscopy revealed multiple depressed lesions in the stomach. Examination with magnifying endoscopy showed branched abnormal vessels along with gastric pits, which were irregularly shaped but were preserved. The second case was a 45-year-old man diagnosed with stage II1follicular lymphoma with duodenal, ileal, and colorectal involvement, as well as lymphadenopathy of the mesenteric lymph nodes. Esophagogastroduodenoscopy performed six years after the diagnosis revealed multiple erosions in the gastric body and angle. Magnifying endoscopic observation with narrow-band imaging showed that the gastric pits were only partially preserved and were destroyed in most of the stomach. Branched abnormal vessels were also seen. Pathological features were consistent with follicular lymphoma in both cases. The structural differences reported between the two cases appear to reflect distinct pathologies. Disappearance of gastric pits in the latter case seems to result from loss of epithelial cells, probably due to chronic inflammation. In both cases, branched abnormal vasculature was observed. These two cases suggest that magnified observations of abnormal branched microvasculature may facilitate endoscopic detection and recognition of the extent of gastric involvement in patients with follicular lymphoma.

Abstract Background and study aims Diagnosis of Meckel’s diverticulum (MD) before surgery may be challenging; double-balloon endoscopy (DBE) facilitates identification of MD in the setting of a gastrointestinal bleeding; however, MD can be found incidentally without this condition. The purpose of this research was to determine specific characteristic of hemorrhagic MD and incidental MD at DBE. Patients and methods Ectopic gastric mucosa enclosed in the MD and/or ulceration were defined as “major findings”; ring-like scar surrounding the MD was defined as “minor finding”. We retrospectively reviewed the medical records of patients affected by MD and analyzed the findings that significantly affected the characterization of MD. Results MD was diagnosed in 33 patients. The axis of the diverticulum was longer in hemorrhagic MD compared to incidental MD (P = 0.031). The amount of transfusion was significantly higher (P = 0.018) in the hemorrhagic MD group. Hemorrhagic MD was significantly more correlated with major findings (P = 0.01) and minor findings (P < 0.01). The specificity of major finding was 100 % while the sensitivity of major and/or minor findings was 96 %. Conclusions The combination of major and minor findings appears to improve the diagnostic ability of hemorrhagic MD avoiding unnecessary diverticulectomy.
