Small bowel cavernous hemangioma: wireless capsule endoscopy diagnosis of a surgical case

Transumbilical single-site laparoscopic treatment of small intestinal cavernous hemangioma in child: a case report

Background

While hemangiomas are the most commonly occurring benign vascular tumors, their occurrence in the gastrointestinal system is rare. This case report presents a unique instance of small intestinal hemangioma in a pediatric patient.

Case description

A 21-month-old girl was admitted to the hospital with a history of "recurrent blood in the stool for one year and anemia for five months." Upon evaluation at our facility, abdominal color ultrasound and enhanced CT scans revealed a protruding mass in the wall of the small intestine, leading to a preliminary diagnosis of small intestinal hemangioma. Subsequent single-site umbilical laparoscopic exploration identified a tumor measuring approximately 6cm×2.5cm×1.2cm on the jejunum wall. Consequently, segmental resection of the intestine was performed, and the postoperative pathological diagnosis confirmed cavernous hemangioma.

Conclusion

Small intestinal hemangiomas, particularly in pediatric patients, are exceptionally rare and challenging to diagnose as the cause of gastrointestinal bleeding prior to surgery. Hence, small intestinal hemangiomas should be considered in such cases. Laparoscopic surgical resection emerges as the optimal approach for addressing small intestinal hemangiomas.

An adult case of small bowel intussusception caused by hemangioma presenting with intestinal obstruction: A case report

INTRODUCTION

Both small bowel intussusception in adults and small bowel hemangioma are rare benign mass lesions. Moreover, a secondary effect of intussusception caused by hemangioma is extremely rare.

PATIENT CONCERNS

A 87-year-old female suffered from intussusception and intestinal obstruction caused by hemangioma located in the small bowel (February 14, 2020), reporting abdominal distention without nausea and vomiting.

DIAGNOSIS

Emergency abdominal and pelvic computed tomography showed an intussusception with the evidence of associated small bowel obstruction. Histological analysis revealed as small intestinal hemangioma accompanied by mesenteric ulcer.

INTERVENTIONS

The patient underwent segmental resection of intussusception of intestine instead of invalid conservative treatment.

OUTCOMES

Although the postoperative pathological results were inconsistent with preoperative imaging examination, the old woman recovered well.

CONCLUSION

The literature on intussusception of small intestine has described several possible causes including hemangioma, which more likely results in gastrointestinal bleeding or abdominal pain. Yet we experienced a rare case presenting as abdominal distention without nausea and vomiting, Therefore, preoperative diagnosis and localization of these lesions is of great importance. We recommend high resolution contrast-enhanced computed tomography and magnetic resonance imaging should be considered in diagnosis while capsule endoscopy is not available owing to the intestinal obstruction, as long as in facilitating surgical excision.

Cavernous hemangioma of the ileum in a young man: A case report and review of literature

BACKGROUND

Small intestinal cavernous hemangioma is a rare disease, especially in the ileum. It is difficult to accurately diagnose due to its hidden location and nonspecific clinical symptoms. Here, we reported a case of ileal cavernous hemangioma with chronic hemorrhage in a 20-year-old man and review the literature to gain a better understanding of this disease.

CASE SUMMARY

The patient complained of intermittent melena and hematochezia for > 3 mo. The lowest hemoglobin level revealed by laboratory testing was 3.4 g/dL (normal range: 12-16 g/dL). However, the gastroscopy, colonoscopy and peroral double-balloon enteroscopy (DBE) showed no signs of bleeding. The transanal DBE detected a lesion at about 340 cm proximal to the ileocecal valve. Thus, we performed an exploratory laparoscopy and the lesion was resected. After the operation, the patient had no melena. Finally, the pathological examination identified the neoplasm as an ileal cavernous hemangioma, thereby resulting in gastrointestinal hemorrhage.

CONCLUSION

This report might improve the diagnosis and treatment of ileal cavernous hemangioma.

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.

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.

Cavernous Hemangioma of the Small Bowel: A Case Report and Literature Review

Hemangiomas of the small intestine are rare and very difficult to diagnose preoperatively. Clinical presentations may include occult or massive gastrointestinal (GI) bleeding, obstruction, intussusception, and perforation. We report a 66-year-old Caucasian male patient with severe anemia secondary to occult GI bleeding from a cavernous hemangioma in the jejunum. A double balloon enteroscopy following capsule endoscopy was performed to obtain biopsy samples, which established the final diagnosis.

Polidocanol injection therapy for small-bowel hemangioma by using double-balloon endoscopy

BACKGROUND AND AIMS

Small-bowel hemangioma is a rare disease that often causes active bleeding. The standard therapeutic method for small-bowel hemangioma is surgical resection. The aim of this study was to evaluate the usefulness of polidocanol injection (PDI) for small-bowel hemangiomas.

METHODS

This study included 12 patients with obscure GI bleeding (6 male; mean age 62 years) with 39 small-bowel hemangiomas; patients were treated with PDI by using double-balloon endoscopy (DBE). EUS with DBE was performed before PDI. The lesions were divided into 2 groups according to tumor size: Group A (size <10 mm; 20 lesions) and group B (size ≥10 mm; 19 lesions). The outcomes of PDI treatment for small-bowel hemangioma were evaluated between the 2 groups. Additionally, in order to standardize the amount of PDI injected, the total amount of polidocanol according to lesion size was calculated.

RESULTS

There was no difference in the location of lesions and treatment times between the 2 groups. Group B had a significantly higher injection time per lesion (P < .05) and amount of polidocanol per lesion than group A (P < .01). Rebleeding occurred in only 1 case (8%). There were no adverse events related to PDI. The contribution ratio between the lesion size and amount of polidocanol showed a correlation (r = 0.77). The optimal amount of polidocanol for small-bowel hemangioma was determined to be 0.2 mL/mm.

CONCLUSIONS

PDI is an easy, safe, and effective method to treat small-bowel hemangiomas.

Small bowel cavernous hemangioma complicated with intussusception: report of an extremely rare case and review of literature

Cavernous hemangioma of the small intestine is a rare disease in adult patients. Intussusception caused by small bowel hemangioma is extremely rare. We report a 20-year-old female presenting with lower abdominal pain and post-prandial bloating. Laboratory studies showed leukocytosis with left shifting and prominent anemia. Computed tomography of the abdomen revealed small bowel intussusception with bowel ischemia. Segmental resection of the intussuscepted jejunum was performed, and the diagnosis of cavernous hemangioma causing intussusception and anemia simultaneously was made.

Giant mesenteric hemangioma of cavernous and venous mixed type: a rare case report

Background

Although vascular tumours are one of the most common soft tissue neoplasms, those occurring in the gastrointestinal system are rare and cases involving mesentery are even further rare. Herein, we reported a rare case of giant hemangioma in mesentery of the small bowel.

Case presentation

A 5-year-old girl was admitted to the emergency room with abdominal pain and vomit for two days. Ultrasonography and computed tomography showed a giant solid-cystic abdominal mass, preferring diagnosis of teratoma. A large neoplasm in the mesentery of the small bowel was found in the surgical exploration, which was then resected with the partial bowel. A brown honeycomb mass in size 16 cm×8 cm×5 cm was observed to adhere to the small bowel, and diagnosed as hemangioma of cavernous and venous mixed type in final pathology.

Conclusion

The mesenteric hemangioma is extremely rare and the variable imaging tests are non-specific, thus the diagnosis is rarely made before surgery and usually established by histopathological investigation after surgery. So the mesenteric hemangioma is supposed to be differentiated in abdominal mass, either in adults or children. Complete surgical resection is the optimal treatment.

Mesenteric Cavernous Hemangioma Involving Small Bowel and Appendix: A Rare Presentation of a Vascular Tumor

We report on a case of cavernous hemangioma of the small bowel mesentery. Fewer than five cases of large mesenteric cavernous hemangioma have been reported in the English literature. Cavernous hemangioma of the small bowel mesentery is extremely rare. A 32-year-old black male presented with 1 week of abdominal pain, nausea, vomiting, and anorexia. He had recently undergone computed tomographic guided biopsy of a pelvic mass at another facility. Repeat CT guided biopsy was nondiagnostic, mesenteric angiography was inconclusive, and magnetic resonance imaging was performed as well. Complete workup was performed to localize primary source of abdominal mass and eventual open biopsy was planned resulting in en bloc resection of the mass, which had invaded the terminal ileum and appendix. Final pathologic diagnosis was cavernous mesenteric hemangioma. The patient experienced a prolonged postoperative ileus and was eventually discharged in stable condition, tolerating a regular diet with adequate bowel and urinary function. Diagnosis of cavernous mesenteric hemangioma is difficult and multiple imaging modalities can prove inconclusive. Adequate biopsy can be difficult to obtain even in patients with small body habitus. Standard of care is resection of entire mass en bloc.

Solitary hemangioma of the small bowel disclosed by wireless capsule endoscopy

A nine-year-old child presented with melena and anemia. She had similar symptoms five months earlier and had undergone an extensive workup with upper gastrointestinal endoscopy and colonoscopy, both normal and 99m-Tc-RBC-scintigraphy which was positive in the right lower quadrant. This time, capsule endoscopy was performed and disclosed an hemangioma with a dark spot suggesting recent bleeding in the ileum. The lesion was resected. Pathological examination revealed a transmural cavernous hemangioma. Small bowel hemangioma is a rare disease. Its diagnosis is extremely difficult and is usually obtained during surgery. Capsule endoscopy is an endoscopic technique that can improve preoperative diagnosis, as reported in the present case.
