BACKGROUND: Rectal cavernous hemangioma is a rare, benign vascular disease that seldom causes lower gastrointestinal bleeding, characterized by a high rate of misdiagnosis and missed diagnoses. Surgical treatment is considered to be relatively effective; however, it is accompanied by certain employed in the treatment of superficial hemangioma, boasting the advantages of minimally invasive surgery, including safety, effectiveness, reduced trauma, and rapid recovery. However, there is a lack of literature regarding the application of foam sclerosing agents for gastrointestinal hemangiomas.
UNASSIGNED: We present a case of a 60-year-old male who was admitted to our hospital with a history of recurrent hematochezia for >1 year and worsening symptoms for 1 week. The patient\'s medical history was unremarkable.
METHODS: Following colonoscopy, nuclear magnetic resonance imaging, computed tomography, and other examinations, the final diagnosis was rectal cavernous hemangioma.
METHODS: Due to the patient\'s refusal of surgery, endoscopic foam sclerotherapy using a lauromacrogol injection was performed after obtaining informed consent from the patient and their relatives.
RESULTS: Post-sclerotherapy, hematochezia symptoms ceased, and no adverse reactions were observed. Two months later, colonoscopy and nuclear magnetic resonance imaging showed that the hemangioma had almost completely disappeared, with only a small amount of tumor remnants, yielding a satisfactory curative effect.
CONCLUSIONS: Our findings indicate that endoscopic injection of a lauromacrogol foam sclerosing agent is a safe, effective, and minimally invasive treatment option for gastrointestinal cavernous hemangiomas.

BACKGROUND: Hemorrhage associated with varices at the site of choledochojejunostomy is an unusual, difficult to treat, and often fatal manifestation of portal hypertension. So far, no treatment guidelines have been established.
METHODS: We reported three patients with jejunal varices at the site of choledochojejunostomy managed by endoscopic sclerotherapy with lauromacrogol/α-butyl cyanoacrylate injection at our institution between June 2021 and August 2023. We reviewed all patient records, clinical presentation, endoscopic findings and treatment, outcomes and follow-up. Three patients who underwent pancreaticoduodenectomy with a Whipple anastomosis were examined using conventional upper gastrointestinal endoscopy for suspected hemorrhage from the afferent jejunal loop. Varices with stigmata of recent hemorrhage or active hemorrhage were observed around the choledochojejunostomy site in all three patients. Endoscopic injection of lauromacrogol/α-butyl cyanoacrylate was carried out at jejunal varices for all three patients. The bleeding ceased and patency was observed for 26 and 2 months in two patients. In one patient with multiorgan failure and internal environment disturbance, rebleeding occurred 1 month after endoscopic sclerotherapy, and despite a second endoscopic sclerotherapy, repeated episodes of bleeding and multiorgan failure resulted in eventual death.
CONCLUSIONS: We conclude that endoscopic sclerotherapy with lauromacrogol/α-butyl cyanoacrylate injection can be an easy, effective, safe and low-cost treatment option for jejunal varicose bleeding at the site of choledochojejunostomy.

Loss of vision after topical injection of sclerosant is a rare and uncommon complication. We describe a case with vision loss following the facial injections of physician-compounded (PCP) foam sclerotherapy which was created by room air. A 3-year-old boy underwent injection of 5ml polidocanol foamed with room air to treat the venous malformation on the cheek near the left orbit. The boy experienced the whole facial swelling on day 2 after the third injection, especially involving the left side, the visual acuity in the left eye was counting fingers at 30 cm and the swelling reduced at 7 days later after referral. Fundus examination on day 15 revealed hemorrhage inferior to the optic disc and fluorescein angiography revealed blocked fluorescein. The OCT on day 15 showed the edema of the nerve fiber layer beside the fovea. The patient\'s hearing was also impaired. PCP foam sclerotherapy with room air produced in typical concentrations, preparations as well as volumes always causes vision loss among children. Continued evaluation on the effects of product, gas, volume, and patient age identify optimal approaches will avoid the toxicity and side-effects caused by facial foam sclerotherapy.

A 67-year-old man with a history of esophageal and gastric varices that were treated endoscopically was treated for Budd-Chiari syndrome and immunoglobulin G4-related sclerosing cholangitis in our facility. Varices in the second portion of the duodenum were revealed in follow-up upper endoscopy. The draining vein formed a venous plexus that was detected on computed tomography. Treatment with interventional radiology was difficult;therefore, endoscopic injection sclerotherapy (EIS) was performed instead. No recurrence has been observed to date. Thus, in this case, EIS for duodenal varices was effective.

In patients with actively bleeding gastric varices, the treatment of choice is the endoscopic use of sclerosing agents such as cyanoacrylate. We report a 69-year-old man who, after being treated with cyanoacrylate, suffered from recurrent febrile episodes. After an extensive study and broad-spectrum antibiotic treatment, discarding other presumably infectious focus, the superinfection of the cyanoacrylate plug was suspected, and its surgical removal was decided. A partial gastrectomy of the gastric fundus, a splenectomy, and a distal pancreatectomy were performed. The patient evolved without fever and without new episodes of bacteremia, but with decompensation of his cirrhosis manifested by ascites, spontaneous bacterial peritonitis, pneumonia, and collections in the pancreatic bed. These complications were managed with medical treatment consisting in a long course of broad-spectrum antibiotics. Thereafter, the patient evolved satisfactorily.

We herein report the first case of rectal stenosis that developed after internal hemorrhoid treatment with aluminum potassium sulfate and tannic acid (ALTA) therapy that was successfully treated by laparoscopic surgery. A 72-year-old man suffered from a fever and rectal stenosis after undergoing internal hemorrhoid treatment with a submucosal injection of ALTA at a previous clinic. Three months after ALTA therapy, he developed frequent mucous and bloody stools. Lower intestinal tract endoscopy revealed circumferential severe rectal stenosis. He was therefore referred to our hospital. The patient suffered from frequent stool build-up and difficulty defecating. We performed balloon-dilatation intervention. The stenosis was not improved at all. Five months after ALTA therapy, we performed laparoscopic low anterior resection with diverting ileostomy. Three months after the operation, ileostomy takedown was performed. The patient has experienced no rectal stenosis in the 2 years since his radical operation.

Management of vascular malformations depends on the size, type, age of the patient, location, dissemination, and depth of penetration. Treatment options include propranolol, which reduces endothelial vessel proliferation, minimally invasive sclerotherapy to induce fibrosis, or surgery. In 1985, Valerian Popescu described a new approach to treatment consisting of intratumoral ligation by compartmentalization. This technique allows for high doses of the sclerosant agent to be delivered as systemic dissemination is restricted by a series of strangulating suture loops that divide the mass into segments. We describe the management and outcome of 2 patients who presented with vascular malformations in the orofacial region and were managed using a Popescu suturing technique. Vascular obliteration was achieved by a series of strangulating suture loops placed percutaneously throughout each lesion using a curved needle with a resorbable material (Vicryl; Ethicon, Somerville, NJ). The aim was to segment the vascular malformation into manageable sections for subsequent injection of a sclerosant. The compartmentalization also ensured that the sclerosant stayed within these compartments and was not washed out into the general circulation. Good esthetic outcomes were achieved in very visible areas such as the commissure and the vermillion border. In these areas, a surgical resection would have certainly caused a disruption of the esthetics of the lips and, in the second case, probably an alteration of function. Intratumoral ligation can be used safely to achieve control of vascular malformations with good esthetic outcomes.

OBJECTIVE: To examine three different methods for evaluating the effect of percutaneous sclerotherapy on limb venous malformations in a series of patients with a relatively long follow-up.
METHODS: The study was a retrospective study.
RESULTS: Thirty-eight patients treated with percutaneous sclerotherapy underwent sclerotherapy, with a median number of sessions of 4 (range, 1-10). They were followed up for 1-60 months (average 12.5 months). The kappa between clinical manifestations and Doppler ultrasound was 0.684 (P < 0.001). The kappa between clinical manifestations and magnetic resonance imaging was 0.217 (P = 0.006). The kappa between Doppler ultrasound and magnetic resonance imaging was 0.323 (P < 0.001). The rate of grade IV patients evaluated by clinical manifestations was significantly higher than that by Doppler ultrasound and magnetic resonance imaging.
CONCLUSIONS: Magnetic resonance imaging is the gold standard for VM imaging. Its consistency with clinical examination and Doppler ultrasound is poor, and Doppler ultrasound and clinical examination could be more appropriate for follow-up imaging after sclerotherapy.
