ABSTRACT Upper gastrointestinal involvement, both gastric and duodenal, is known to occur in both Crohn disease and ulcerative colitis (UC). However, the frequency and types of inflammation in upper gastrointestinal biopsies in patients with UC has not been well studied, especially in a controlled study.
Twenty-four esophageal, 59 gastric, and 40 duodenal biopsies from 69 UC patients were reviewed. These were compared with 35 esophageal, 66 gastric, and 46 duodenal biopsies from a control group of 97 consecutive patients of similar age and sex distribution. The pattern and extent of inflammation were noted in each biopsy.
There were 3 types of gastric inflammation that occurred more in UC patients than in controls, and the differences were statistically significant. The most common was an intense focal gastritis, present in 29% of UC gastric biospies, compared with 9% of controls. Twenty-two percent of UC patients had a basal mixed inflammation compared with 8% of controls, and 20% of the UC patients had superficial plasmacytosis compared with 6% of controls. There were no esophageal inflammations that occurred more commonly in UC than controls. Four UC patients and no controls had diffuse chronic duodenitis, also a statistically significant difference. All 4 UC-duodenitis patients were among the 10 with previous colectomies, and all 4 patients had pouchitis. Only 1 of the 4 UC-colectomy patients without duodenitis developed pouchitis.
Most UC patients have no upper gastrointestinal inflammation in biopsies, and most of the inflammations they have are not unique. The most common upper gastrointestinal inflammatory pattern in patients with UC is focal gastritis, followed by gastric basal mixed inflammation and superficial plasmacytosis. The one unique upper gastrointestinal inflammation in UC patients is diffuse chronic duodenitis, present in 10% of patients who had duodenal biopsies, and in 40% of UC patients who had colectomy and all of these patients had pouchitis. This association strongly suggests that diffuse chronic duodenitis in UC patients who have colectomy is a strong predictor of pouchitis.

    ABSTRACT: Endoscopic oesophageal biopsies are common in daily pathology practice. Inflammation and damage of the oesophageal mucosa is known as oesophagitis and is common worldwide. A variety of physical, chemical and infectious agents cause oesophagitis. The oesophagus has a limited range of responses to a wide variety of injuries, and so histopathological features of different diseases often overlap. The pathologist is reliant on the endoscopist for the 'macroscopic description' of the oesophagus. Access to the endoscopic images enhances the pathologist's overall interpretation of the case. Correlating clinical, endoscopic and microscopic findings may be crucial in arriving at the correct diagnosis. In this review, we present clinicopathological descriptions of the major types of oesophagitis.

    ABSTRACT: Inflammatory complications of ileal pouch-anal anastomosis (IPAA), including pouchitis and Crohn's disease (CD) of the pouch, are common in patients with restorative proctocolectomy for ulcerative colitis. It is not clear whether these inflammatory conditions can affect upper GI tract. The aim of the study was to evaluate correlation between duodenal and pouch histology in patients with healthy and diseased pouches. All IPAA patients who had esophagogastroduodenoscopy with biopsy after colectomy (N = 96) were included. H&E slides of gastric, duodenal, neo-terminal ileum, and pouch body biopsies were blindly re-reviewed by an expert GI pathologist for acute and chronic inflammation. Demographic and clinical variables and pouch outcome were analyzed. There was a significant correlation between acute inflammation in the duodenum as measured by neutrophil infiltration score and the presence of chronic pouchitis (kappa coefficient = 0.21, P < 0.05). Intraepithelial lymphocytosis of the duodenum, though uncommon, only occurred in patients with irritable pouch syndrome, chronic pouchitis, or CD of the pouch. Crypt distortion of duodenal epithelium was only seen in patients with inflammatory or structural diseases of the pouch, including acute (18.2%) and chronic (5%) pouchitis, CD of the pouch (14.3%), and surgical complications of the pouch (14.4%). Histologic evaluation of duodenal biopsy may provide additional information in patients with ileal pouches, as patients with normal histology of the pouch may have an abnormal duodenal histology.

    ABSTRACT: Inflammatory bowel disease is associated with increased risk of cholelithiasis. However, the histologic patterns in gallbladders have not been extensively studied. This study is designed to characterize the histopathologic features of cholecystectomy specimens in inflammatory bowel disease patients, compared to a control group. Cholecystectomy specimens in 78 Crohn's disease patients and 50 ulcerative colitis patients were reviewed. These were compared with 93 cholecystomies from noninflammatory bowel disease patients of approximate age and sex. The pattern and extent of inflammation was noted. Marked chronic cholecystitis was present in 12% of ulcerative colitis patients (P<0.05) and 10.3% of Crohn's disease patients (P>0.05), compared to 4.3% of the noninflammatory bowel disease control group. Eight percent of ulcerative colitis patients (P<0.05) and 2.6% of Crohn's disease patients (P>0.05) had acute serositis, compared to 0% of the noninflammatory bowel disease control. The third inflammatory pattern, nodular lymphoid aggregates, was significantly increased in Crohn's disease patients after adjusting for the effect of cholelithiasis. Nodular lymphoid aggregates were found in 21.2% of Crohn's disease patients and 9.7% of ulcerative colitis patients without cholelithiasis, compared to 5% of noninflammatory bowel disease controls without cholelithiasis, a statistically significant difference between the Crohn's disease and control groups (P<0.05). Inflammatory bowel disease patients show similar inflammatory patterns in cholecystectomy specimens compared to the general population. However, two inflammatory patterns that occur more often in ulcerative colitis patients are marked chronic cholecystitis and acute serositis, while nodular lymphoid aggregates are more common in Crohn's disease patients.
