Pancake kidney and jejunal atresia: An uncommon dual anomaly detected prenatally-A case report.

Pancake kidney is a renal fusion anomaly with only a few reported prenatal diagnoses. Other structural anomalies beyond the urogenital system may also be associated. This study describes a dual anomaly case detected prenatally, comprising of pancake kidney and jejunal atresia. A postnatal abdominal ultrasound confirmed both kidneys were fused in the midline at the aortic bifurcation level, along with a type 3b jejunal atresia. Based on the available limited evidence about pancake kidney, renal functions appear to remain largely preserved and unaffected as in our case according to 6 months of follow-up. However, further investigation is needed to explore any potential association with chromosomal and structural abnormalities in selected cases.

Crohn's disease with multiple jejunum and ileum lesions: A case report.

Crohn's disease (CD) affecting the jejunum and ileum is uncommon and its diagnosis can be challenging. This case report describes a 35 year old male patient who had been e xper iencing intermi ttent periu mbilica l pain , di arrho ea and fever for five years. Despite undergoing gastroscopy, co lo noscopy and capsule endoscopy; no s ignific ant abnormal ities were found. This case was se en at the Shenzhen Ho spital of Traditional Chinese Medi ci ne; Shenzhen, China. However, the pa tient u nder went a doubl e-balloon enteroscopy (DBE), which revealed multip le ulcers in the jejunum and ileum, leadin g to a confirmed diagnosis of CD. The patient was successfully treated with infliximab t o rel ieve sy mptoms. DBE can be par ticularly valuable in diagnosing CD in young patients with symptoms when conventional endoscopic techniques have been unsuccessfu l. This case highlights the impor tance of considering small bowel disease in patients wit h CD symptoms and the potential benefits of DBE in diagnosing such cases.

Jejunal Inflammation in Crohn's Disease: Comparison between Diffusion Weighted Magnetic Resonance Imaging and Video Capsule Endoscopy.

BACKGROUND: Jejunal disease is associated with worse prognosis in Crohn's disease. The added value of diffusion weighted imaging for evaluating jejunal inflammation related to Crohn's Disease is scarce. OBJECTIVES: To compare diffusion weighted imaging, video capsule endoscopy, and inflammatory biomarkers in the assessment of Crohn's disease involving the jejunum. METHODS: Crohn's disease patients in clinical remission were prospectively recruited and underwent magnetic resonance (MR)-enterography and video capsule endoscopy. C-reactive protein and fecal-calprotectin levels were obtained. MR-enterography images were evaluated for restricted diffusion, and apparent diffusion coefficient values were measured. The video capsule endoscopy-based Lewis score was calculated. Associations between diffusion weighted imaging, apparent diffusion coefficient, Lewis score, and inflammatory biomarkers were evaluated. RESULTS: The study included 51 patients, and 27/51 (52.9%) with video capsule endoscopies showed jejunal mucosal inflammation. Sensitivity and specificity of restricted diffusion for video capsule endoscopy mucosal inflammation were 59.3% and 37.5% for the first reader, and 66.7% and 37.5% for the second reader, respectively. Diffusion weighted imaging was not statistically associated with jejunal video capsule endoscopy inflammation (P = 0.813). CONCLUSIONS: Diffusion weighted imaging was not an effective test for evaluation of jejunal inflammation as seen by video capsule endoscopy in patients with quiescent Crohn's disease.

Radiographic and ultrasonographic appearance of a jejunal torsion-volvulus in a dog.

A 1.5-year-old male neutered, 5 kg, Dachshund was referred for anorexia and vomiting for several days' duration. Radiographs revealed concern for a small intestinal obstruction. Ultrasonography revealed a severely distended segment of jejunum containing echogenic fluid that abruptly narrowed, twisted, and transitioned into normal jejunum, along with the presence of a distinct "whirl sign" that resulted from the intestinal segments twisting around themselves. This, in addition to the absence of flow on power Doppler interrogation, was compatible with a focal jejunal torsion-volvulus. The torsion-volvulus was surgically confirmed, a resection and anastomosis was performed, and the dog recovered uneventfully.

An Unusual Small Bowel Phytobezoar Successfully Resolved by Double-balloon Enteroscopy.

We herein report a very unusual case of small bowel obstruction caused by phytobezoar in a 69-year-old woman who consumed a large amount of bracken. The patient presented with nausea and vomiting. Computed tomography revealed an air-filled foreign body in the jejunum that had likely caused the small bowel obstruction. A fibrous foreign body diagnosed as a phytobezoar was detected using double-balloon enteroscopy. The obstruction was successfully resolved by crushing the phytobezoar repeatedly using a snare. Small bowel obstructions caused by phytobezoars are often treated with surgical interventions. However, endoscopic fragmentation using a snare is a minimally invasive treatment alternative.

Obscure Gastrointestinal Bleeding Caused by a Small Intestinal Lymphatic-venous Malformation: A Case Report with a Literature Review.

A 44-year-old woman presented with severe anemia. We strongly suspected gastrointestinal bleeding; however, esophagogastroduodenoscopy, colonoscopy, and computed tomography showed no bleeding sources. Video capsule endoscopy revealed an actively bleeding submucosal lesion within the jejunum. Double-balloon enteroscopy revealed a 20-mm continuously bleeding submucosal lesion in the distal jejunum. We suspected small intestinal vascular malformation and performed surgical resection. The resected specimen pathologically comprised dilated, thin-walled lymphatic channels and blood vessels involving the small intestinal submucosa. Therefore, the patient was diagnosed with small intestinal lymphatic-venous malformation. Postoperatively, the patient recovered well, and recurrence was not observed.

Jejunal varix with a high transfusion requirement: therapy with cyanoacrylate with radiological control by double-balloon enteroscopy.

A jejunal varix with high transfusion requirement is treated by double-balloon enteroscopy with cyanoacrylate/ lipiodol with radiological control. The patient had not gastrointestinal hemorrhage or transfusion requeriment after 8 months follow up. Our recent previous article in Rev Esp Enferm Dig on advanced therapeutics by enteroscopy is referenced, providing this new therapeutic possibility.

Diagnostic and Therapeutic Challenges in the Management of Acute Massive Overt Bleeding of Jejunal Gastrointestinal Stromal Tumours: Case Series.

INTRODUCTION: Jejunal gastrointestinal stromal tumours (GIST) are rare mesenchymal tumours. Acute massive overt bleeding from jejunal GIST is very rare and poses both diagnostic and therapeutic challenges in emergent conditions. METHODS: A case series with retrospective analysis of prospectively maintained database of patients presenting with acute massive overt bleeding secondary to histologically proven jejunal GIST was done. Clinical characteristics, endoscopic and imaging diagnostic features, histological findings, surgical procedures and outcomes in these patients were studied. RESULTS: Three patients were included in this case series. Mean age of presentation was 49.0 years with two male and one female patient. All three patients presented with melena and hemodynamic instability, resuscitated with adequate blood transfusions. Routine endoscopic assessment were inconclusive. Multiphasic Computed Tomographic Angiography (CTA) revealed hypodense hypervascular mass in jejunum in all three patients. One patient was unresponsive to blood transfusion and underwent emergency exploratory laparotomy. One patient underwent laparoscopic resection and reconstruction. Mean length of hospital stay was 5.3 days. Histopathological examination confirmed jejunal GIST in all three patients with microscopically negative resection margins. Two patients were disease free till 18-month follow-up and the one patient lost to follow-up after 1 year. CONCLUSION: Multiphasic CTA is a single-step diagnostic tool for localisation of bleed and assessment of tumour characteristics in emergent conditions. Surgical resection is the mainstay of treatment for both control of bleed and to provide oncologically clear resection margins.

Jejunal lymphangioma.

We herein report a case of jejunal lymphangioma. A CT scan showed non-enhancing cystic masses in the jejunum. Enteroscopy revealed multiple cystic swelling with whitish carpet-like villi. Histopathology disclosed dilated lymphatic channels, lined by a single layer of endothelial cells, which were positive for the lymphatic endothelial marker by the immunohistochemical staining. Clinical manifestations of intestinal lymphangioma are briefly discussed.

Jejunal obstruction due to jejunocolic congenital band in a 12-year-old child: a case report.

BACKGROUND: A congenital band is an uncommon abnormality that can be found anywhere along the gastrointestinal tract. Intestinal obstruction caused by an anomalous congenital band is very rare in children. To the best of our knowledge, no cases of congenital bands extending from the descending colon to the jejunum have been reported in the English literature CASE PRESENTATION: Herein, we present the case of a 12-year-old Syrian patient with intestinal obstruction due to a congenital band extending from the mesentery of the descending colon to the mesentery of the jejunum with an entrapped loop of jejunum between the band and the mesentery. The location of the obstruction was determined by upper gastrointestinal contrast radiography, but the cause of the obstruction was diagnosed intraoperatively. The band was excised without intestinal resection. CONCLUSION: Prediagnosis of congenital bands can be challenging, and surgery is required. When making a bowel obstruction differential diagnosis, it is important to keep this type of band in mind.

Indocyanine green fluorescence imaging improves the assessment of blood supply of interposition jejunum.

OBJECTIVES: The blood supply of the transposed jejunum was assessed by ICG fluorescence imaging in jejunal interposition, and the correlation with anastomotic leakage or transposed jejunal necrosis was analyzed, aim to explore the value of the application ICG fluorescence imaging technology. METHODS: 84 esophageal reconstructions with jejunal interposition without supercharging were retrospectively analyzed. Intraoperatively, the blood supply of transposed jejunal was observed using ICG fluorescence endoscopy. ROC curve of T1/2 was constructed to calculate the corresponding T1/2max value of the region where the transposed jejunal want to be anastomosed with esophageal stump, the relationship between T1/2max value and anastomotic leakage or transposed jejunal necrosis was analyzed. RESULTS: The occurrence of anastomotic leakage and transposed jejunal necrosis was 9.5%, In the ROC curve, the maximum value of the Youden index was 0.691, the T1/2max value was 5.35 s. When T1/2max value > 5.35 s correspondingly, the probability of anastomotic leakage or transposition jejunal necrosis was 33.3% (7/21); when T1/2max value ≤ 5.35 s, the probability of anastomotic leakage or transposition jejunal necrosis was 1.6% (1/63). The difference between the two groups was statistically significant (P < 0.05). CONCLUSION: ICG fluorescent imaging can effectively assess the blood supply of transposed jejunum. When T1/2max > 5.35, the possibility of the incidence rate of anastomotic leakage or transposed jejunum necrosis increases, this will remind the operators to take corresponding remedial measures during operation.

New sonographic feature (C-sign) to improve the prenatal accuracy of jejunal atresia.

OBJECTIVES: To describe a new sonographic feature of the C-sign for prenatal diagnosis of jejunal atresia and evaluate its role in prenatal jejunal atresia, particularly preceding bowel dilatation and polyhydramnios. METHODS: This was a retrospective study from a tertiary maternal hospital. Patients with prenatal sonographic examination and confirmed small bowel atresia postdelivery were included. All sonographic images were reviewed by two senior sonographers. Comparison of sonographic images between prenatal jejunal and ileal atresia using the C-sign resembles the shape of the entire duodenum and other traditional sonographic features. The control group without bowel atresia was assessed for the presence of the C-sign. RESULTS: The C-sign and combined bowel dilatation with polyhydramnios were more frequent in jejunal atresia than ileal atresia, but the C-sign can be used to detect jejunal atresia earlier. The C-sign can be more likely to diagnose jejunal atresia in persisting bowel dilatation and polyhydramnios. The C-sign was not reported in any of the control fetuses. CONCLUSION: The C-sign is a new sonographic feature that can be used to improve the prenatal accuracy and early detection of jejunal atresia. However, further prospective validation is needed.

Ultrasonography of the gastrointestinal tract of toco toucans (Ramphastos toco).

Baseline data for wall thickness in healthy toucans can be used to diagnose disease in sick individuals. This study aimed to evaluate the use of ultrasonography for the examination of the gastrointestinal tract of healthy toco toucans (Ramphastos toco). Ten non-anaesthetized healthy adult toco toucans were evaluated. Food was withheld for 3 h prior to the ultrasound examination. Longitudinal and transverse images of the gastrointestinal tract were obtained using ventromedian cranial and ventromedian caudal approaches to evaluate the morphology and stratification. The wall thickness of the sections was measured: proventriculus and ventriculus, duodenum, jejunum/ileum, and cloaca. Additionally, the thickness of the mucosal layer of the duodenum and jejunum/ileum was also measured. Subsequently, the ratios of the duodenal wall thickness to the duodenal mucosa layer and the total wall thickness of the jejunum/ileum to the jejunum/ileum layer mucosa were stablished. The wall thickness of the proventriculus was significantly higher than the wall thickness of ventriculus. The wall thickness of the duodenum was significantly higher than the wall thickness of jejunum/ileum. The mean ratios of the duodenal wall thickness to the duodenal mucosa layer and the wall thickness of the jejunum/ileum to the jejunum/ileum layer were 83.15% and 80.07%, respectively. In conclusion, it was possible to assess the stomach and intestines using ultrasound examination in healthy toco toucans, due to their medium body size and no interference by surrounding air sacs.

Transgastric Feeding Tube Insertion into the Jejunum after Esophagectomy: Direct Puncture of the Gastric Conduit.

PURPOSE: To evaluate the safety and efficacy of percutaneous ultrasound (US)-guided direct puncture of a reconstructed gastric conduit after esophagectomy for performing a percutaneous radiologic gastrojejunostomy. MATERIALS AND METHODS: Between 2014 and 2020, 26 consecutive patients with esophageal cancer (mean age, 70 years ± 8.3) with a total of 27 attempts of percutaneous radiologic gastrojejunostomy for postsurgical enteral feeding at the National Cancer Center Hospital were included in this study. One patient required a repeat procedure because of persistent anorexia after the removal of the first tube. All patients except 1 had a gastric conduit reconstructed via a retrosternal route. All procedures were performed under local anesthesia with moderate sedation and analgesia. A gastric conduit was directly punctured with an 18-gauge needle under ultrasonographic guidance, followed by feeding tube insertion into the proximal jejunum. Technical details of the procedures, technical success (defined as adequate tube placement), procedure-related complications, and clinical outcomes were reviewed. RESULTS: The mean procedure time was 25 minutes ± 15, and technical success was obtained in every attempt. Minor complications included mild local pain (n = 7), unintentional tube removal (n = 2), local abdominal wall hematoma (n = 1), and superficial cellulitis (n = 1); no major complications were observed. During a mean follow-up period of 118.3 days ± 85.8, 13 patients resumed oral intake, and the feeding tube could be removed in 4 patients. No procedure-related deaths occurred. CONCLUSIONS: The US-guided direct puncture technique is feasible for percutaneous gastrojejunal tube insertion in postsurgical patients with esophageal cancer with gastric conduit reconstruction.

Intrapericardial Hernia after Transdiaphragmatic Approach of Intrathoracic IVC.

Trauma and abdominal surgery that involves the diaphragm and pericardium rarely ends up in post-operative visceral herniation into the pericardial cavity. Urgent intervention is crucial to restore the cardiac output and prevent bowel strangulation. A case of a patient with intrapericardial hernia following nephrectomy for renal cell carcinoma and en block resection of an IVC neoplasmatic thrombus via transdiaphragmatic approach is presented.

Jejunal Dieulafoy lesion with intraintestinal calcification on computerized tomography: A case report.

RATIONALE: A Dieulafoy lesion is a rare cause of gastrointestinal (GI) bleeding, especially in the jejunum, and the presence of calcifications on CT might be suspicious of the diagnosis. PATIENT CONCERNS: We describe a 72-year-old woman with anemia and melena. Hemoglobin was 6.0 g/dL, and the stools were positive for occult blood (4+). Blood pressure was 116/54 mm Hg. Physical examination showed pale face and pitting edema in both lower limbs. Abdominal computerized tomography showed calcification in the small intestine of the left lower abdomen. Capsule endoscopy showed a blood clot. DIAGNOSES: Dieulafoy lesion. INTERVENTIONS: Single balloon endoscopy was performed via the oral approach and showed a blood clot on the suspected submucosal tumor of jejunum. A hemostatic clip was placed at the base of the lesion to allow the surgeon to locate it during the operation. Laparoscopy was performed, and the lesion was resected. OUTCOMES: The postoperative pathology showed a Dieulafoy lesion. The lower extremity edema subsided. GI bleeding did not recur over 1 year of follow-up, and hemoglobin was 12.2 g/dL. A Dieulafoy lesion is a rare cause of GI bleeding, and it is even rarer in the jejunum. LESSONS: A Dieulafoy lesion does not have special imaging features, but the presence of calcifications in the small intestine on computerized tomography might be suspicious of the diagnosis. When endoscopic treatment is difficult, surgical treatment could be considered.

Enterolith ileus and jejunal diverticulitis from jejunal diverticulosis: the complications of a rare gastrointestinal entity.

Small bowel diverticulosis is rare. False diverticula form in the jejunum, and less commonly, the ileum. As with their large bowel counterparts, these diverticula provide a pocket for stasis of bowel content, leading to the formation of enteroliths. This case report highlights two complications from jejunal diverticulosis: jejunal diverticulitis and a small bowel obstruction as a result of enterolithiasis; the latter being a rare entity which should be a differential diagnosis for any individual presenting with gastrointestinal obstructive symptoms and radiological evidence of small bowel diverticulosis.
