Blue rubber bleb nevus syndrome: endoscopic removal of the gastrointestinal hemangiomas

Treatment options for gastrointestinal bleeding blue rubber bleb nevus syndrome: Systematic review

OBJECTIVES

Blue rubber bleb nevus syndrome (BRBNS) is a rare challenging cause of gastrointestinal bleeding. We performed a systematic review of case reports and case series on BRBNS to gather information on the treatment options currently available.

METHODS

All studies reporting a case of BRBNS in humans were evaluated. Papers were ruled out if CARE criteria and explanations on patient's selection, ascertainment, causality, and reporting were not respected or identified. PROSPERO 2021 CRD 42021286982.

RESULTS

Blue rubber bleb nevus syndrome was treated in 106 cases from 76 reports. 57.5% of the population was under 18 years old, and up to 50% of the cases reported a previous treatment. Clinical success was achieved in 98 patients (92.4%). Three main types of interventions were identified: systemic drug therapy, endoscopy, and surgery. After BRBNS recurrence or previous therapy failure, systemic drug therapy emerged as a preferred second-line treatment over endoscopy (P = 0.01), but with a higher rate of reported adverse events when compared with surgery and endoscopy (P < 0.001). Endoscopic treatment was associated with a higher number of required sessions to achieve complete eradication when compared with surgery (P < 0.001). No differences between the three main areas were found in the overall follow-up time (P = 0.19) or in the recurrence rate (P = 0.45).

CONCLUSION

Endoscopy, surgery, and systemic drug therapy are feasible treatment options for BRBNS. Systemic drug therapy was the favorite second-line treatment after endoscopic failure or recurrence of BRBNS, but adverse events were more frequently reported.

Gastric Hemangioma Treated with Argon Plasma Coagulation in a Newborn Infant

Gastric hemangioma in the neonatal period is a very rare cause of upper gastrointestinal bleeding. We present a case of hemangioma limited to the gastric cavity in a 10-day-old infant. A huge, erythematous mass with bleeding was observed on the lesser curvature side of the upper part of the stomach. Surgical resection was ruled out because the location of the lesion was too close to the gastroesophageal junction. Medical treatment with intravenous H₂ blockers, octreotide, packed red blood cell infusions, local epinephrine injection at the lesion site, application of hemoclip, and gel-form embolization of the left gastric artery did not significantly alter the transfusion requirement. Hemostasis was achieved with endoscopic argon plasma coagulation (APC). After two sessions of APC, complete removal of the lesion was achieved. APC was a simple, safe and effective tool for hemostasis and the ablation of gastric hemangioma without significant complications.

An atypical presentation of blue rubber bleb nevus syndrome

A 69-year-old white man presented with several episodes of hematochezia. Colonoscopy demonstrated multiple colonic blebs localized mainly in the distal transverse colon. Esophagogastroduodenoscopy, capsule endoscopy, and computed tomography of the abdomen did not reveal any abnormalities. The patient required several blood transfusions and eventually required a subtotal colectomy with ileosigmoid anastomosis for definitive bleeding control. Pathology was remarkable for multifocal vascular ectasia, consistent with the diagnosis of blue rubber bleb nevus syndrome.

Multi-system progressive angiomatosis in a dog resembling blue rubber bleb nevus syndrome in humans

A six-year-old, neutered, female golden retriever was presented with generalised, dark purple to black cutaneous nodules and gastrointestinal haemorrhage. Histopathologically, all cutaneous nodules were diagnosed as benign cavernous haemangiomas. Endoscopic analysis revealed similar nodules in the oesophagus, stomach and duodenum. At laparotomy, similar nodules were seen on the visceral peritoneal lining of abdominal organs. Metastatic haemangiosarcoma was ruled out based on histological features and lack of primary tumour in spleen, liver or heart ultrasonographically. Blood loss associated with gastrointestinal haemorrhage was managed with blood transfusion. To the authors' knowledge, this is the first canine case of multi-system progressive angiomatosis resembling blue rubber bleb nevus syndrome in humans.

Hemangiomas of the pelvis

Hemangiomas of the colon and rectum are rare but often misdiagnosed causes of hematochezia. They are characterized by the clinical triad of recurrent episodes of painless rectal bleeding, multiple ectopic phleboliths on plain radiographs, and cutaneous hemangiomas. The majority of these tumors involve the rectosigmoid region. Diffuse cavernous lesions are the most common histological type. Endoscopy is important to define the extent and number of lesions. Imaging by computed tomography or magnetic resonance imaging is used to define invasion into pelvic structures. Surgical resection with preservation of the sphincters is the recommended treatment.

Blue rubber bleb nevus syndrome: extensive small bowel vascular lesions responsible for gastrointestinal bleeding

Blue Rubber Bleb Nevus Syndrome is a rare condition characterised by multiorgan venous malformations, in particular of cutaneous area and the gastrointestinal (GI) tract. We report here a child with chronic iron deficiency anaemia, melena and skin lesions. She had severe hypochromic microcytic anaemia. Upper and lower endoscopy revealed hundreds of red-bluish polypoid lesions involving the entire GI tract primarily of the small bowel. Due to localisation of the most severe lesions, the patient responded well to surgical treatment, allowing a sustained clinical remission.

Blue rubber bleb nevus syndrome: treatment of multiple gastrointestinal hemangiomas with argon plasma coagulator

Blue rubber bleb nevus syndrome is a rare clinical entity characterized by the formation of multiple blue or purplish rubbery cavernous hemangiomas on the skin and other epithelial surfaces. Involvement of the gastrointestinal tract is common and often presents with crippling anemia as a result of chronic occult blood loss. While surgical extirpation is an option for symptomatic hemangiomas in the intestine, endoscopic therapy is more appealing for lesions found in the stomach and colon. Here we report the successful use of argon plasma coagulation in the management of an adult with multiple hemangiomas in her colon and terminal ileum.

A case of blue rubber bleb nevus syndrome

Blue rubber bleb nevus syndrome is a rare disorder that is characterized by multiple recurrent vascular malformations, such as hemangioma, and these primarily involve the skin and the gastrointestinal tract. It may also involve the brain, liver, lungs, and skeletal muscles. A 14-year-old female visited our hospital with a chief complaint of dizziness; upon examination, we found multiple recurrent hemangiomas on the skin and gastrointestinal tract. We were able to diagnose her as suffering from blue rubber bleb nevus syndrome and we treated her with methylprednisolone (2 mg/kg/day for 1 month and 1 mg/kg/day for additional 3 months). We report on this case along with a review of the literature.

Blue Rubber Bleb Nevus Syndrome

Blue rubber bleb nevus syndrome (BRBNS) is a rare disease characterized by the presence of cutaneous and gastrointestinal (GI) hemangiomas. These BRBNS-associated hemangiomas, possibly numbering into the hundreds, may also be identified in multiple visceral locations.

Although the presence of benign cutaneous lesions is of small concern, GI lesions are cause for bleeding. Heavy visceral organ involvement can lead to intravascular coagulation, consumptive coagulathopy, and organ failure. Therefore, GI-related complaints, anemia, the visual identification of a cutaneous blue-colored lesion located on the upper extremity or trunk, and multiple visceral hemangiomas involving a large portion of the organ may indicate the presence of BRBNS. It is important that this unusual combination of patient signs, symptoms, and sonographic findings be presented to the interpreting physician to facilitate inclusion of this rare condition as a possible differential diagnosis to be considered.

Tc-99m red blood cell imaging in a patient with blue rubber bleb nevus syndrome

Blue rubber bleb nevus syndrome, first discovered in 1860 by Gascoyen, is a rare syndrome characterized by multiple venous malformations (hemangiomas) of the skin and in the gastrointestinal tract. These hemangiomas may be found in the skin, GI tract, central nervous system, thyroid, parotid, eyes, oral cavity, musculoskeletal system, lungs, kidneys, liver, spleen, and bladder, and carry a significant potential for serious bleeding. We report a case of a 9-year-old patient who presented with bloody stools and was referred for localization of the bleeding site. A Tc-99m labeled red blood cell (RBC) scan showed no evidence of active lower GI bleeding but demonstrated multiple venous malformations throughout the body. Tc-99m labeled red blood cell imaging may be helpful to delineate the extent of involvement in patients with blue rubber bleb nevus syndrome.

Blue rubber bleb nevus syndrome: surgical eradication of gastrointestinal bleeding

OBJECTIVE

We report the largest clinical experience to date of surgically treated patients with blue rubber bleb nevus syndrome (BRBNS).

SUMMARY BACKGROUND DATA

BRBNS is a rare congenital disorder presenting with multifocal venous malformations of the skin, soft tissues, and gastrointestinal (GI) tract. Patients with BRBNS develop anemia from chronic GI bleeding, and require lifelong treatment with iron and blood transfusions. An aggressive surgical approach to treat the GI venous malformations of BRBNS has been considered unlikely to be successful because of the large number of lesions, their position throughout the GI tract, and the likelihood of recurrence. Based on our belief that eradicated lesions would not recur, we undertook the removal of all GI tract lesions in an effort to eliminate bleeding.

METHODS

Ten patients with BRBNS were treated from 1993 to 2002. Lesions were identified using complete GI endoscopy. The multiple venous malformations were removed by a combination of wedge resection, polypectomy, suture-ligation, segmental bowel resection, and band ligation.

RESULTS

Patient ages ranged from 2 to 36 years, and patients received an average of 53 prior blood transfusions. A mean of 137 focal GI venous malformations per patient were resected at operation (range 4-557), with a mean operative duration of 14 hours (range 7-23 hours). Only 1 patient who had a less extensive procedure developed recurrent GI bleeding. The mean follow-up period was 5.0 years (range 2.9-10.3 years).

CONCLUSIONS

We believe that an aggressive excisional approach is indicated for the venous anomalies that cause GI bleeding in BRBNS.

Venous malformations in blue rubber bleb nevus syndrome: variable onset of presentation

Blue rubber bleb nevus syndrome (BRBNS) is a rare disorder characterized by discrete venous malformations of varying size and appearance that are present on the skin and within the gastrointestinal tract. The characteristic cutaneous lesions consist of deep-blue, soft, rubbery blebs, which are easily compressible. A serious complication is gastrointestinal bleeding. Because venous malformations were described historically as cavernous hemangiomas, the lesions of BRBNS were also inappropriately called hemangiomas in the literature. We describe 3 cases to delineate the venous malformations of BRBNS and to highlight their variable onset of presentation and progression. In one case, a venous malformation was noted during a prenatal ultrasound evaluation at 5 months gestation. The other 2 cases demonstrated a lack of the classic cutaneous lesions at birth. BRBNS consists of multiple venous malformations, rather than hemangiomas as described. Subcutaneous venous malformations may occasionally be the sole presenting finding in patients with this unusual syndrome, and may be evident even in the prenatal period.

Blue rubber bleb nevus syndrome

Blue rubber bleb nevus syndrome is a rare disorder characterized by distinctive cutaneous and gastrointestinal venous malformations that usually cause massive or occult gastrointestinal hemorrhage and iron deficiency anemia secondary to the bleeding episodes. It is even a rare cause of gastrointestinal hemorrhage during childhood. We describe a 6-year-old boy who had multiple venous malformations all over his body. He also suffered from several episodes of melena, chronic anemia, and growth retardation. The endoscopic examination of the gastrointestinal tract revealed multiple bluish-black sessile and polypoid venous malformations in various sizes. It was possible to remove the largest venous malformations causing massive bleeding during colonoscopy.
