Preoperative detection and localization of small bowel hemangioma: Two case reports

Duodenal Hemangioma as a Rare Cause of Gastrointestinal Bleeding: A Case Report and Literature Review

Duodenal hemangiomas are benign vascular tumors caused by haphazard vascular proliferation within the duodenal wall. Although rare, duodenal hemangiomas could lead to rapidly progressive life-threatening gastrointestinal (GI) bleeding that requires urgent intervention. The diagnosis of duodenal hemangioma often requires direct visualization of the lesion either endoscopically or surgically, as well as histopathological examination. Treatment options include endoscopic resection, laser coagulation, sclerotherapy, or in a specific subset of patients, open or laparoscopic surgical intervention. We herein report a case of a 46-year-old female presenting with signs and symptoms of chronic GI bleeding. The patient underwent upper endoscopy and was found to have an ulcerated mass in the proximal duodenum consistent with the diagnosis of duodenal hemangioma. This case highlights the importance of including duodenal hemangioma in the differential of upper GI bleeding. It also underscores the significance of surgical intervention in treating duodenal hemangioma, as well as the crucial role of employing endoscopy in the diagnostic and therapeutic management of this condition.

Cavernous haemangioma of the duodenum with acute massive bleeding in the ascending portion: a case report

Duodenal cavernous haemangiomas are rare, benign disorders, and massive gastrointestinal (GI) bleeding is a rare clinical condition. The present case report describes a 50-year-old male patient who presented with severe, ongoing haematochezia. A peripheral blood smear at the time of admission showed significant anaemia, and haemoglobin level was 52 g/l (normal range, 120–175 g/l). Albumin level was also low at 28 g/l (normal range, 40–55 g/l). Standard computed tomography (CT) showed mural thickening and relative lumen stenosis in the ascending (fourth) portion of the duodenum. Contrast-enhanced CT using hypotonic solution revealed the lesions to be hypervascular haemangiomas. Laparotomy and segmental duodenum resection were performed, and the first jejunal limb was anastomosed using a side-to-end technique. Histopathological examination confirmed the diagnosis of cavernous haemangioma. The patient showed marked improvement during follow-up. The present case findings emphasize that duodenal haemangioma is possible without a history of chronic anaemia, and should remain a consideration in differential diagnosis for patients presenting with massive GI bleeding. CT is useful for preoperative diagnosis of massive bleeding, and surgery with segmental resection is usually curative.

A localization method for wireless capsule endoscopy using side wall cameras and IMU sensor

Localizing the endoscopy capsule inside gastrointestinal (GI) system provides key information which leads to GI abnormality tracking and precision medical delivery. In this paper, we have proposed a new method to localize the capsule inside human GI track. We propose to equip the capsule with four side wall cameras and an Inertial Measurement Unit (IMU), that consists of 9 Degree-Of-Freedom (DOF) including a gyroscope, an accelerometer and a magnetometer to monitor the capsule’s orientation and direction of travel. The low resolution mono-chromatic cameras, installed along the wide wall, are responsible to measure the actual capsule movement, not the involuntary motion of the small intestine. Finally, a fusion algorithm is used to combine all data to derive the traveled path and plot the trajectory. Compared to other methods, the presented system is resistive to surrounding conditions, such as GI nonhomogeneous structure and involuntary small bowel movements. In addition, it does not require external antenna or arrays. Therefore, GI tracking can be achieved without disturbing patients’ daily activities.

Cavernous Hemangioma: A Rare Cause of Massive Lower Gastrointestinal Bleeding

Due to their rarity, intestinal hemangiomas are not commonly considered as a cause of gastrointestinal (GI) bleeding. This report describes a patient who presented with massive, recurrent lower GI bleeding secondary to a cavernous hemangioma of the small intestine. The source of GI bleeding could not initially be identified despite using numerous diagnostic modalities. The lesion was eventually revealed on diagnostic laparoscopy and small bowel resection was performed.

Successful Endoscopic Sclerotherapy Using Polidocanol for Small Bowel Hemangioma

Small-bowel hemangiomas are a possible source of gastrointestinal bleeding for which there is no established treatment approach. In this report, we describe the case of a 58-year-old woman who presented with hematochezia and who was diagnosed with small bowel hemangioma. She was successfully treated using endoscopic sclerotherapy. Initial capsule endoscopy revealed bleeding in the ileum. Subsequent double-balloon enteroscopy showed a 2-cm, bluish-purple, ileal submucosal tumor with an overlying protrusion. The lesion was responsible for the hematochezia and was treated with intralesional injection of polidocanol. The hematochezia completely resolved and at 4 months after sclerotherapy, the size of the lesion was significantly reduced.

Jejunal Submucosal Hemangioma as a Cause of Massive Gastrointestinal Bleeding: A Case Report

Small intestinal hemangiomas are uncommon tumors that frequently present with gastrointestinal bleeding (GIB). Diagnosis, detection, and treatment can be challenging and may require surgical intervention. An 81-year-old female presented with melena. Video capsule endoscopy revealed active bleeding in the proximal jejunum and push enteroscopy identified a polypoid nodule with central umbilication. The patient underwent laparoscopic resection and jejunal submucosal hemangioma was detected. Submucosal hemangiomas are a rare cause of GIB. As the most common site of submucosal hemangiomas is the mid-jejunum, they are not easy to detect. Surgical intervention is usually required for a definitive diagnosis and definitive treatment.

Small bowel racemose hemangioma complicated with obstruction and chronic anemia: A case report and review of literature

BACKGROUND

Gastrointestinal hemangiomas are rare benign tumors. According to the size of the affected vessels, hemangiomas are histologically classified into cavernous, capillary, or mixed-type tumors, with the cavernous type being the most common and racemose hemangiomas being very rare in the clinic. Melena of uncertain origin and anemia are the main clinical manifestations, and other presentations are rare. Due to the rarity of gastrointestinal hemangiomas and lack of specific manifestations and diagnostic methods, preoperative diagnoses are often delayed or incorrect.

CASE SUMMARY

We report a 5-year-old girl who presented with abdominal pain, nausea, and vomiting for a duration of 10 h. The laboratory studies showed prominent anemia. Computed tomography and contrast-enhanced computed tomography of the abdomen revealed a small bowel obstruction caused by a giant abdominal mass. Segmental resection of the ileal lesions was performed through surgery, and the final pathology results revealed a diagnosis of racemose hemangioma complicated by a small bowel obstruction and simultaneous chronic anemia.

CONCLUSION

The current report will increase the understanding of the diagnosis and treatment of gastrointestinal hemangiomas and provide a review of the related literature.

A Single Small Bowel Hemangioma Detected by Video Capsule Endoscopy in a Patient Presenting with Iron-deficiency Anemia - Two Case Reports

Hemangioma of the small intestine is a rare vascular malformation which mostly presents as occult gastrointestinal bleeding and iron-deficiency anemia. Patients are often asymptomatic except of fatigue due to anemia. Hemangiomas can arise anywhere in the luminal gastrointestinal tract, with jejunum as the most commonly involved site. They are very hard to recognize mostly due to their localization. Video capsule endoscopy and balloon-assisted enteroscopy have very much improved preoperative diagnostics and made major contribution to establishing the diagnosis - which was very difficult in the past and almost all cases were diagnosed during or after the operation. Surgical resection is still the conventional treatment modality, although with the improvement of endoscopic therapeutic interventions (endoscopic mucosal resection, argon-plasma coagulation) there are more therapeutic possibilities.

Management of small bowel polyps: from small to big

PURPOSE OF REVIEW

Benign small bowel polyps or mass are clinically poorly distinguishable from malignant small bowel masses, and the diagnostic conditions are almost the same. The important point for clinicians is first to take advantage of the different available diagnostic tools to optimize the diagnostic algorithm of a small bowel polyp or mass. Next, according to the clinical situation, associated disease or sporadic situation, the difficulty is to adapt the treatment decision to the patient situation.

RECENT FINDINGS

The last 20 years have been marked by the development of major diagnostic tools for small bowel diseases (capsule endoscopy, cross-sectional imaging with enteroclysis and balloon-assisted enteroscopy) and by the major decrease of intra-operative enteroscopy as a diagnostic mean.

SUMMARY

On the basis of considerable development of capsule endoscopy and the improvement of cross-sectional small bowel imagining, small bowel polyps represent now a frequent clinical situation for gastroenterologists.

Small intestinal hemangioma: Endoscopic or surgical intervention? A case report and review of literature

BACKGROUND

Hemangioma of the small intestine is a rare vascular malformation. Before the advent of capsule endoscopy (CE) and balloon-assisted enteroscopy (BAE), preoperative diagnosis of this disease was extremely difficult.

CASE SUMMARY

In this study, we report a 24-year-old female with a large transmural small bowel cavernous hemangioma, which was diagnosed with CE and BAE preoperatively and removed successfully using minimally invasive surgery. Meanwhile, we perform a literature review of the studies about intestinal hemangiomas published after 2000. Literature review revealed that 91.9% of the lesions were diagnosed preoperatively by CE and/or BAE and 45.9% of them were treated endoscopically, which is a marked improvement compared to before 2000. Therefore, CE and BAE are useful modalities for the preoperative diagnosis of hemangiomas in the small intestine.

CONCLUSION

Endoscopic treatment of intestinal hemangioma is generally prudent and might be suitable for multiple, relatively small lesions.

Small bowel bleeding: cause and the role of endoscopy and medical therapy

PURPOSE OF REVIEW

The objective is to provide an overview on the cause of small bowel bleeding. We discuss the role of small bowel endoscopy in the management of small bowel bleeding and provide an outline of pharmacotherapy that can be additionally beneficial.

RECENT FINDINGS

Small bowel capsule endoscopy (SBCE) is the initial diagnostic investigation of choice in small bowel bleeding. Computed tomography (CT) can be helpful in the context of small bowel tumours. Device-assisted enteroscopy (DAE) enables several therapeutic procedures such as argon plasma coagulation (APC) and haemoclip application. It can also guide further management with histology or by marking culprit lesions with India ink. A persistent rate of rebleeding despite APC is increasingly being reported. Pharmacotherapy has an emerging role in the management of small bowel bleeding. Somatostatin analogues are a well tolerated class of drugs that can play an additional role in the management of refractory bleeding secondary to small bowel angioectasias.

SUMMARY

SBCE is useful in determining the cause of small bowel bleeding. DAE offers an endoscopic therapeutic approach to small bowel bleeding replacing surgery and intraoperative enteroscopy. Pharmacotherapy, in addition to endotherapy, can play an important role in the management of multifocal, recurring bleeding small bowel lesions.
