BACKGROUND
Bezoars are conglomerates of indigestible foreign material that can be found in the gastrointestinal tract. Gastric ulcer, gastrointestinal perforation, and intestinal obstruction are the main complications. Acute pancreatitis secondary to bezoar is rare. Here, we present a rare case of a migratory gastric bezoar complicated by acute pancreatitis and small bowel obstruction after dissolution therapy.
CASE SUMMARY
A-65-year-old woman underwent gastroscopy because of epigastric pain, which revealed a huge bezoar and a gastric ulcer 10 d prior. The patient was discharged with a prescription of drinking 1 L Coca-Cola daily for 6 d, without repeat gastroscopy. However, she suddenly developed epigastric pain, nausea and vomiting for 3 d. Abdominal computed tomography (CT) revealed mild inflammation of the pancreas. Magnetic resonance cholangiopancreatography showed no abnormalities in the pancreatic duct or common bile duct. The nasogastric tube still showed drainage of more than 1.6 L of dark fluid each day after symptomatic treatment. Abdominal CT re-examination suggested intestinal obstruction. Esophagogastroduodenoscopy revealed a huge yellowish hard mass in the jejunal lumen, and we used the basket and net to fragment the bezoar. She was discharged with a good outcome.
CONCLUSION
Endoscopic therapy is the first choice for gastric bezoars. When mechanical disintegration cannot be achieved, timing of repeat endoscopy is important during Coca-Cola dissolution therapy.

A 77-year-old female who had an acute severe abdominal pain was taken to the emergency room in the previous hospital. CT scans showed jejunum and ileum wall thickening and fatty deposits around the small intestinal tract, and gastrointestinal perforation could not be ruled out. By using single anal and oral balloon endoscopy, we observed mild edema with petechial erythema, shallow erosions with edematous mucosa and ulcers with surrounded disrupted villous structures at the jejunum and ileum. Histological analysis revealed atypical lymphocytes infiltrating the small intestinal mucosa demonstrating intraepithelial lymphocytosis. Immunohistochemical staining revealed that CD3, CD7, and CD56 staining was positive, and CD4, CD5, and CD8 staining was negative in infiltrated lymphocytes. We made the diagnosis of monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) with the combination of HE staining and IHC. PET-CT showed abnormal uptake in irregular wall thickening of the small intestine, lymph nodes, ribs, spine and pelvic bone. She was treated with chemotherapy (etoposide, prednisolone, oncovin, cyclophosphamide, hydroxydaunorubicin) and is still alive 1 year after the diagnosis. We reported the various endoscopic findings in the same MEITL patient by using single balloon endoscopy. We also summarized endoscopic characteristics of MEITL patients.

A 66-year-old man with vomiting and weight loss was referred to our hospital. Abdominal computed tomography showed small bowel obstruction caused by a presumed small intestinal tumor. Single-balloon endoscopy showed an ulcerated tumor and marked stenosis of the jejunum. Immunohistochemical staining suggested the tumor to be poorly differentiated or undifferentiated carcinoma. The patient underwent open surgical resection of the jejunal tumor and regional lymph nodes both to improve the quality of life of the patient and to possibly get a cure of the presumed jejunal carcinoma. Pathological examination of the excised tumor and lymph nodes including para-aortic lymph nodes showed large-sized tumor cells and massive lymphocyte infiltrates. Immunostaining showed the tumor cells to be OCT3/4, AE1/AE3, CD117, and D2-40 positive, leading to the diagnosis of metastatic seminoma. With the preoperative diagnosis of a presumed burned-out tumor of the testis, the patient underwent left high orchiectomy. Pathological examination of the left testis showed marked scar tissue, no teratoma elements, and no residual tumor cells. Under the final diagnosis of regressed seminoma, the patient has received combination chemotherapy using bleomycin, etoposide, and cisplatin as adjuvant chemotherapy. Surgical oncologists should take regressed seminoma into their differential diagnosis when the biopsy specimens of the presumed intestinal malignancy show poorly differentiated or undifferentiated atypical cells with massive lymphocyte infiltrates, especially in postpubertal men. Confirmation of a malignant noninvasive component should be another important clue to the appropriate differential diagnosis when choosing between metastatic seminoma and poorly differentiated or undifferentiated intestinal primary malignancies.

INTRODUCTION
Gastrointestinal (GI) cytomegalovirus (CMV) infection coexisting with or followed by a diagnosis of inflammatory bowel disease (IBD) is infrequently reported. Not recognizing this condition may delay IBD diagnosis in patients with GI-CMV disease who do not or partially respond to antiviral agents, which could consequently result in unsatisfied treatment outcomes.
PATIENT CONCERNS
Two immunocompetent patients with no known underlying GI conditions presented with acute bloody diarrhea. The first patient developed diarrhea and hematochezia after admission to intensive care unit (ICU) because of severe alcoholic pancreatitis for 10 days duration. Computed tomography abdomen showed segmental jejunal thickening. The other patient presented with a 1-week history of severe bloody diarrhea which required ICU admission. Colonoscopy showed multiple ulcers along terminal ileum and colon.
DIAGNOSIS
These 2 patients were initially diagnosed with CMV jejunitis and ileocolitis, respectively, based on endoscopic and histopathologic findings. Both had partial response to treatment with 3 weeks of intravenous ganciclovir. Crohn disease was suspected because of persistent ulcerations on the follow-up endoscopy with the presence of pathological features of chronic inflammation and disappearance of previously detected CMV-infected cells.
INTERVENTION
Both patients were treated with systemic corticosteroids and azathioprine.
OUTCOMES
Both patients had complete clinical improvement. Prednisolone could be tapered off in 6 months. Follow-up video capsule endoscopy (VCE) at 6 months showed improvement of mucosal inflammation and ulcers, but neither were completely healed in the first patient. Follow-up colonoscopy at 6 months showed complete resolution of ulcers and inflammation in the second patient.
LESSONS
IBD should be suspected in patients with a diagnosis of GI-CMV disease who are immunocompetent and have a partial response to antiviral agents. This clinical scenario could be caused by either CMV infection activating immune response resulting in IBD onset, or CMV infection superimposed on pre-existing latent IBD.

INTRODUCTION
Gastric heterotopia rarely occurs in the small intestine beyond ligament of Treitz. Most cases of jejunal gastric heterotopia have been reported in children and young adults. Herein we report a case of jejunal gastric heterotopia presenting as a perforation peritonitis in a middle-aged adult.
PRESENTATION OF CASE
A 51-year-old male presented with abrupt onset abdominal pain of 1 day duration. Physical examination revealed abdominal tenderness and rebound tenderness as well as costovertebral angle tenderness. Abdominal computed tomography revealed pneumoperitoneum, suggestive of hollow viscus perforation. At emergency laparotomy, a perforation site was discovered in the jejunum 100 cm distal to the ligament of Treitz. On macroscopic examination, the mucosa contained a 3 × 4 cm ill-defined, shallow ulceration next to the perforation site. Microscopically, the mucosa surrounding the perforation site revealed gastric heterotopia which consisted of gastric foveolar epithelium along with abundant pyloric glands and a few fundic glands.
DISCUSSION
To the best of our knowledge, this case is the presumed oldest jejunal gastric heterotopia patient presenting with perforation peritonitis ever reported.
CONCLUSION
Jejunal gastric heterotopia should also be considered in the differential diagnosis of perforation peritonitis in adults.

BACKGROUND
Crohn's disease (CD) can involve the upper gastrointestinal (GI) tract as well as the small and large bowel. PillCam colon capsule endoscopy (PCCE-2) enables observation of the whole GI tract, but its diagnostic yield for CD lesions in the whole GI tract remains unknown.
AIM
To elucidate the diagnostic yield of PCCE-2 in patients with CD.
METHODS
Patients with CD who underwent PCCE-2 and double-balloon endoscopy (DBE) using oral and anal approaches were evaluated for CD lesions in the whole GI tract. We divided the small bowel into three segments (jejunum, ileum, and terminal ileum), and the large bowel into four segments (right colon, transverse colon, left colon, rectum). Detection of ulcer scars, erosion, ulcers, bamboo joint-like appearance, and notch-like appearance was assessed in each segment. The diagnostic yield of PCCE-2 was analyzed based on the DBE results as the gold standard.
RESULTS
Of the total 124 segments, the sensitivities of PCCE-2 for ulcer scars, erosion, and ulcers were 83.3%, 93.8%, and 88.5%, respectively, and the specificities were 76.0%, 78.3%, and 81.6%, respectively. For the 60 small bowel segments, the sensitivities were 84.2%, 95.5%, and 90.0%, respectively, and the specificities were 63.4%, 86.8%, and 87.5%, respectively. For the 64 large bowel segments, the sensitivities were 80.0%, 90.0%, and 83.3%, respectively, and the specificities were 84.7%, 72.2%, and 77.6%, respectively.
CONCLUSION
PCCE-2 provides a high diagnostic yield for lesions in the whole GI tract of patients with CD. Thus, we recommend its use as a pan-enteric tool in clinical settings.

The differential diagnosis for ulcerating small bowel strictures is extensive and includes exposure to non-steroidal anti-inflammatory drugs (NSAIDs), Crohn's disease, infections, gastrointestinal lymphoma and vasculopathy. It also encompasses the exceptionally rare and poorly understood diagnosis of cryptogenic multifocal ulcerative stenosing enterocolitis (CMUSE), often a diagnosis of exclusion and considerable difficulty. We present a case of persistent proximal jejunal ulcerating stenoses in a 75-year-old Caucasian man, which continued despite cessation of NSAIDs. After extensive clinical, radiographic, laboratory and ultimately surgical pathological appraisal-as well as failure to improve with both misoprostol and budesonide-he was diagnosed with CMUSE and managed with limited small bowel resection. In the presentation of this case, we aim to underscore the diagnostic challenges that clinicians face in differentiating CMUSE from other more common diagnoses, particularly NSAIDs-induced enteropathy.

Celiac Disease (CeD) is an immune-mediated inflammatory disorder of the small intestine, affecting genetically susceptible individuals when exposed to gluten. Small intestinal biopsy interpretation has been the "gold standard" for celiac disease (CeD) for over 50 years. Despite today's availability of sensitive and specific serological tests, the histopathological features from mucosal biopsy play a key role in diagnosing when CeD is suspected. Such a diagnostic approach requires a multidisciplinary team to optimize both tissue sampling and interpretation via the interaction between the pathologist and the gastroenterologist. Pathologists of the Italian Group of Gastrointestinal Pathology (GIPAD-SIAPEC), together with a member (TR) of the Italian Society of Technicians (AITIC) and an expert gastroenterologist (CC), provide position statements as a practical tool for reading and interpreting the report. Moreover, a position statement was formulated about the recently described condition known as Non-Celiac Gluten Sensitivity (NCGS). Within such a diagnostic setting, both the architectural abnormalities of the duodenal mucosa, namely glandular hyperplasia, and villous atrophy and the number of intraepithelial T-lymphocytes should be well highlighted. Ancillary tests such as anti-CD3 stain are useful for an accurate count of the intraepithelial T lymphocytes when CeD or NCGS is suspected. Moreover, anti-CD3 and anti-CD8 stains are recommended in patients not responding to the gluten-free diet (GFD) to confirm a diagnosis of Refractory Celiac Disease (RCeD). Diagnostic clues about the differential diagnosis of both CeD and RCeD have also been rendered.

Endoscopic ultrasonography-guided gastroenterostomy using a lumen-apposing metal stent has emerged as a novel technique in the palliative treatment of malignant gastric outlet obstruction. Endoscopic ultrasonography-guided gastroenterostomy seems to have the potential to provide long-lasting patency in a minimally invasive manner. Low reintervention rates have been described. We report two cases with early lumen-apposing metal stent dysfunction, compromising patency. One case showed food impaction after three weeks, and hyperplastic tissue overgrowth with a buried distal flange six weeks after stent placement. The latter was successfully treated by argon plasma coagulation, stent removal, and deployment of a larger-diameter lumen-apposing metal stent. The second case showed a narrowed luminal diameter of the stent and jejunal pressure ulcerations after three weeks. The narrowing was successfully treated by balloon dilation. Eight weeks later, hyperplastic tissue overgrowth at the distal flange of the stent and a gastro-colonic fistula were diagnosed, followed by extensive reconstructive surgery.

Thrombotic microangiopathy (TMA) is a serious complication following kidney transplantation. Although intestinal TMA is a major organ injury and causes abdominal pain, diarrhea and bloody stools, the clinical and endoscopic characteristics of small intestinal TMA remain unclear. Here, we report a drug-induced small intestinal TMA, which did not meet the laboratory-defined TMA criteria but was diagnosed by balloon-assisted enteroscopy (BAE). A 32-year-old woman who underwent kidney transplantation at the age of 10 years complained of abdominal pain, diarrhea and bloody stools one month after starting everolimus (EVE) as an immunosuppressant. Although she did not meet the diagnostic criteria for TMA serologically, BAE revealed a circumferential ulcer in the jejunum, and the pathological findings of a biopsy specimen showed microvascular thrombi, compatible with intestinal TMA. Her symptoms improved upon the discontinuation of EVE, demonstrating that EVE can cause drug-induced intestinal TMA. The present case suggests that BAE should be performed when abdominal pain, diarrhea, and bloody stools occur in patients receiving immunosuppressive medication following kidney transplantation, even if there is no evidence of TMA according to the laboratory definition.
