Treatment of ectopic varices with portal hypertension

Outcomes of endoscopic treatment for acute duodenal ectopic variceal bleeding: a single-center retrospective case series

Duodenal ectopic variceal hemorrhage is a rare portal hypertension complication that can easily be clinically missed. Once hemorrhage occurs, the rebleeding and fatality rates are high. There is no unified standard for its treatment, we reported the endoscopic treatment of eight patients admitted to our department between January 2014 and May 2021, Endoscopic band ligation and endoscopic cyanoacrylate injection were performed in five and three cases, respectively. The hemostasis success rate was 100%, no postoperative bleeding occurred, and there were no serious complications. Duodenal varices disappeared in four cases after 2-12 months. In conclusion, Endoscopic therapy is an ideal treatment method for acute duodenal ectopic variceal hemorrhage.

Ileocecal Mesentery Arteriovenous Malformation as a Rare Cause of Ectopic Variceal Bleeding in a 58-Year-Old Male With Cirrhosis

Ectopic varices can be defined as dilated portosystemic venous collaterals that are located at a site other than the esophagus or stomach. These varices can be seen in patients with underlying portal hypertension, but bleeding from them is quite rare. The bleeding usually occurs in patients with a history of intra-abdominal surgery and adhesions. These varices are commonly found in the duodenum or rectum, but they can be present anywhere along the gastrointestinal tract. Currently, there are no well-established guidelines regarding the diagnosis and management of these variceal bleeds, and further investigations with randomized controlled or large-scale trials are required. Here, we report an unusual case of ectopic variceal bleeding from an ileal arteriovenous malformation (AVM), which presented as syncope associated with an acute abdomen in a patient with no prior history of intra-abdominal surgery.

Endoscopic injection sclerotherapy for treating recurrent bleeding of small bowel angioectasias

BACKGROUND

There is still no consensus on the preferred endoscopic therapy for small bowel angioectasias (SBAs). The aim of this study was to evaluate effectiveness and safety of endoscopic injection sclerotherapy (EIS) for treating recurrent bleeding of SBAs.

METHODS

Sixty-six adult patients diagnosed with SBAs by capsule endoscopy (CE) or double-balloon enterscopy (DBE) examinations were enrolled in this retrospective study from September 2013 to September 2021. The patients were divided into an EIS group (35 cases) and a control group (31 cases) according to whether they underwent EIS treatment. Clinical characteristics, medical histories, lesion characteristics, main laboratory indicators, treatments, and outcomes were collected. The rates of re-bleeding, re-admission, and red blood cell (RBC) transfusion were compared between different groups after discharge. The rates of hospitalization and RBC transfusion were compared between before admission and after discharge in both groups. Odds ratios (ORs) and 95% confidence intervals (CIs) were used in the multivariate logistic regression analysis to assess relative factors for re-bleeding.

RESULTS

All the rates of re-bleeding, re-admission and RBC transfusion after discharge in the EIS group were significantly lower than those in the control group (all P < 0.05). The rates of hospitalization and RBC transfusion after discharge were significantly lower than those before admission in the EIS group (both P < 0.05), while those did not reach significant differences in the control group (both P > 0.05). Multivariate logistic regression analysis showed that RBC transfusion before admission (OR, 5.655; 95% CI, 1.007-31.758, P = 0.049) and multiple lesions (≥ 3) (OR, 17.672; 95% CI, 2.246-139.060, P = 0.006) were significant risk factors of re-bleeding, while EIS treatment (OR, 0.037; 95% CI, 0.005-0.260, P < 0.001) was a significant protective factor. No endoscopic adverse events were observed during hospitalization and none of the enrolled patients died within 12 months after discharge.

CONCLUSION

EIS treatment had good effectiveness and safety for treating recurrent bleeding of SBAs, which could be considered as one of the first-line endoscopic treatment options for SBAs.

Percutaneous radiological interventions of the portal vein: a comprehensive review

The portal vein is the largest vessel supplying the liver. A number of radiological interventions are performed through the portal vein, namely for primary pathologies of the portal vein, for inducing liver hypertrophy or to treat the sequelae of portal hypertension among others. The routes used include direct transhepatic, transjugular, and, uncommonly, trans-splenic and through subcutaneous varices. Portal vein embolization and transjugular intrahepatic portosystemic shunt are among the most common portal vein interventions that are performed to induce hypertrophy of the future liver remnant and to treat complications of portal hypertension, respectively. Other interventions include transhepatic obliteration of varices and shunts, portal vein thrombolysis, portal vein recanalization, pancreatic islet cell transplantation, and embolization of portal vein injuries. We present a detailed illustrative review of the various radiological portal vein interventions.

A Case of Esophagojejunal Variceal Rupture after Total Gastrectomy and Esophagojejunostomy Successfully Treated with Percutaneous Transhepatic Obliteration under Dual-balloon Occlusion of Feeding and Draining Veins

We present the case of a man in his 60s with bleeding esophagojejunal varices occurring after gastrectomy for gastric carcinoma. Percutaneous transhepatic portography depicted the esophagojejunal varices originated from the jejunal vein and drained into the azygos vein. A 5-French occlusion balloon catheter was wedged into the jejunal vein and a 3-French occlusion balloon catheter into one drainage channel of the esophagojejunal varices via the azygos vein. Selective antegrade jejunal venography under dual-balloon occlusion revealed entire esophagojejunal varices with good stagnated and well-opacified contrast medium. Subsequently, 12 mL of 5% ethanolamine oleate-contrast medium mixture was slowly injected into the esophagojejunal varices. He was discharged without complications one week after the procedure, and abdominal computed tomography demonstrated the disappearance of the esophagojejunal varices six months after the procedure.

A Case of Duodenal Variceal Rupture during Atezolizumab and Bevacizumab Treatment for Hepatocellular Carcinoma

Duodenal varices are detected infrequently, and their rupture is very rare. We encountered an 87-year-old man who developed duodenal varices rupture during chemotherapy with atezolizumab and bevacizumab (ATZ/BV) for hepatocellular carcinoma. We identified massive bleeding of a ruptured varix in the horizontal portion of the duodenum with emergency esophagogastroduodenoscopy (EGD). Successful hemostasis was achieved by endoscopic injection sclerotherapy with Histoacryl. Although ATZ/BV can cause esophageal varices rupture, there have been no cases of duodenal varices rupture. We should take care to check the duodenal varices as well as esophagogastric varices before ATZ/BV treatment.

Acute Colonic Variceal Bleeding in a Cirrhotic Patient Treated by Modified Balloon-occluded Retrograde Transvenous Obliteration: A Case Report

Colonic varices are an uncommon type of ectopic varices that can occur due to underlying liver cirrhosis and portal hypertension. They form a very rare cause of lower gastrointestinal bleeding that can result in massive hemorrhage. We present a 38-year-old woman with a background of ulcerative colitis complicated by primary sclerosing cholangitis-induced liver cirrhosis presenting with fresh rectal bleeding. The colonoscopy failed to identify the source of bleeding. Then, computed tomography scan showed multiple dilated tortuous venous collaterals around the descending colon that extended into the colonic submucosa and drained via the left ovarian vein representing colonic varices. She underwent balloon-occluded retrograde transvenous obliteration (BRTO), which successfully embolized these varices with no significant complications. Despite there being no established management guidelines for colonic variceal bleeding, BRTO is a minimally invasive procedure that can be considered as good option for the treatment of these varices, especially when other alternatives are not applicable.

Report of a case of cirrhotic portal hypertension with ectopic varices in the bilateral pulmonary hilar

Here, we report the case of patient cirrhosis with esophageal and gastric fundal varices who developed rare ectopic varices in the bilateral pulmonary hilar after repeated endoscopic treatments (tissue adhesive for gastric fundal varices + esophageal variceal ligation + esophageal variceal sclerotherapy) accompanied by serious shortness of breath. After transjugular intrahepatic portosystemic shunt + gastric coronary vein embolization, the shortness of breath was relieved, and the portography review indicated that the ectopic varices in the pulmonary hilar were significantly improved.

Massive gastrointestinal bleeding due to ectopic varix in distal duodenum: a case report

Duodenal ectopic varices (DEV) are an uncommon etiology of upper gastrointestinal bleeding and are associated with high mortality. Both the diagnosis and management of DEV are challenging. Multiple treatment modalities exist including endoscopic guided management (ligation and sclerotherapy), surgical resection, transvenous obliteration and transjugular intrahepatic portosystemic shunt (TIPS), but management depends on the underlying vascular anatomy and underlying pathology. We present a case of a 41-year-old man with a history of an alcohol use disorder, prior splenic vein thrombosis as a complication of pancreatitis who presented with massive gastrointestinal bleeding, and was ultimately diagnosed with distal duodenal ectopic varix, which contained inflow from a medial branch of the superior mesenteric vein and outflow into the left renal vein. He was successfully treated with transjugular portosystemic shunt and coil embolization.

Effectiveness and safety of endoscopic treatment for duodenal variceal bleeding: a systematic review

Duodenal varix is a rare condition that involves massive bleeding, diagnostic difficulties, and a high rate of rebleeding and mortality. The purpose of this study was to systematically review endoscopic treatment for duodenal variceal bleeding to evaluate its effectiveness and safety. We searched PubMed, Embase, Web of Science, and the Cochrane Library up to 21 November 2019. Ninety-two studies containing 156 patients were finally included, and individual data from 101 patients (mean age: 52.67 ± 13.82 years, male: 64.4%) were collected and further analyzed. We used an analysis of variance and χ2 or Fisher's exact tests to analyze individual data from 101 patients. The cause of duodenal variceal bleeding was cirrhosis-related intrahepatic portal hypertension (IPH) in 76.2% of patients. The overall rates of initial hemostasis and treatment success of endoscopic treatment for duodenal variceal bleeding were 89.1 and 81.2%, respectively. The median duration of follow-up was 4.5 (1.0, 12.0) months. The overall rates of rebleeding and mortality were 8.9 and 13.9%, respectively. Among a variety of endoscopic treatments available, only the initial hemostasis rate was significantly different between the endoscopic injection sclerotherapy and endoscopic tissue adhesive (ETA) groups (72.7 vs. 94.7%, P = 0.023); differences in treatment success, rebleeding, mortality, and adverse events were not statistically significant among the four groups. Endoscopic intervention is a feasible, well tolerated, and effective modality for the treatment of duodenal variceal bleeding. Among the variety of endoscopic treatments available, ETA with cyanoacrylate may be preferable for duodenal variceal bleeding.

Ectopic variceal bleeding after hepatobiliary surgery: A case report

RATIONALE

Jejunal varices are rare in portal hypertension and are often difficult to diagnose and treat. Herein, we present a case of gastrointestinal bleeding due to jejunal varices after hepatobiliary surgery.

PATIENT CONCERNS

A 69-year-old man presented with recurrent massive gastrointestinal bleeding. He underwent partial right hepatectomy and cholangiojejunostomy 2 years prior to the first onset of bleeding. Two sessions of endoscopic vessel ligation for esophageal varices were performed afterwards, and hematemesis resolved completely, but massive melena still recurred during the following 5 years.

DIAGNOSIS

The patient was diagnosed with jejunal varices caused by portal venous stenosis after hepatobiliary surgery.

INTERVENTION

Portal venous angioplasty using balloon dilation and stent implantation was performed.

OUTCOMES

After the intervention procedure, the patient did not experience any onset of gastrointestinal bleeding during follow-up.

LESSONS

Hepatopancreatobiliary could lead to the formation of jejunal varices. The combined use of capsule endoscopy, contrast-enhanced computed tomography, and sometimes portal venography is a promising strategy to search for jejunal varices. Transcatheter angioplasty appears to be a safe and effective method for treatment of jejunal varices in certain appropriate cases.

Thrombin Is an Effective and Safe Therapy in the Management of Bleeding Gastric Varices. A Real-World Experience

Variceal haemorrhage is a severe complication of liver disease with high mortality. Human recombinant thrombin has gained popularity in the management of variceal haemorrhage. We report on the use of thrombin for gastric and ectopic varices at a regional tertiary care centre. This was a retrospective observational study. Patients with portal hypertension who received endoscopic injection of recombinant thrombin were identified and data collected on haemostasis and rebleeding rates, complications and mortality. Patients were grouped by indication for thrombin injection: gastric/oesophageal/ectopic varices and endoscopic band ligation (EBL)-induced ulceration. 155 patients (96M/59F, mean age 58.3 years) received endoscopic thrombin injection. Mean volume of thrombin injected at index endoscopy was 9.5 ml/2375IU. Initial haemostasis was achieved in 144 patients (92.9%). Rebleeding occurred in a total of 53 patients (36.8%) divided as follows: early rebleeding (<5 days from index endoscopy)-26 patients (18%); rebleeding within 30 days-42 patients (29.1%); delayed rebleeding (> 30 days)-11 patients (7.6%). There was statistically significant difference in rate of initial haemostasis between Child-Pugh A/B patients vs Child-Pugh C (p = 0.046). There was no significant difference in rebleeding rates between different indication groups (p = 0.78), by presence of cirrhosis or by Child-Pugh Score. All-cause mortality at 6 weeks was 18.7%; 1-year mortality 37.4% (median follow-up 48 months). There was no significant difference in mortality between groups (p = 0.37). No significant adverse events or complications were reported. Thrombin is effective and safe for gastric varices and other portal-hypertension-related bleeding including oesophageal varices, ulcers secondary to EBL and ectopic varices.

Clinical characteristics and efficacy of endoscopic treatment of gastrointestinal ectopic varices: A single-center study

BACKGROUND

Ectopic varices (EcVs) may cause massive bleeding, which can be difficult to control, with a high rate of mortality. The purpose of this study was to analyze the clinical characteristics of EcVs and the efficacy of endoscopic treatment.

METHODS

From January 2008 to July 2017, the clinical data of 150 patients with EcVs in our center were retrospectively collected and analyzed.

RESULTS

One hundred and fifty patients with EcVs (male 74.7%), with a mean age of: 54.1 ± 14.6 years were included. The prevalence of EcVs was 0.92% in gastrointestinal varices. Cirrhosis was the most common cause of EcVs (67.0%). The rates of bleeding were 57.14%, 4.34%, 30.0%, 33.3%, and 100% in the duodenal varices rectal varices, colonic varices, anastomotic varices, and small bowel varices, respectively. An age under 55 years, varices in the duodenum, and erythema were considered risk factors for EcV bleeding. Endoscopic treatments were performed in 15 patients with EcV bleeding. The follow-up period of the patients who underwent endoscopic treatment ranged from 0.5 to 24 months. The overall rate of treatment success was 73.33% for endoscopic treatment of EcV bleeding. The overall rates of rebleeding and mortality during 2 years were as high as 53.3% and 26.7%, respectively.

CONCLUSION

Age, erythema, and the location of EcVs are considered risk factors for EcV bleeding, and the rate of bleeding is higher in patients with duodenal varices than in those with other EcVs. Endoscopic treatment is safe, effective, and feasible for controlling EcV bleeding.

A case of percutaneous transhepatic portal vein stent placement and endoscopic injection sclerotherapy for duodenal variceal rupture occurring during chemotherapy for unresectable perihilar cholangiocarcinoma

Duodenal varices are ectopic varices that are rare but can involve any site along the digestive tract outside the gastroesophageal region. Ectopic variceal bleeding is generally massive and life threatening; the mortality rate is approximately 40%. Up to 17% of ectopic varices occur in the duodenum. However, duodenal varices pose a significant therapeutic challenge due to the lack of standard treatment guidelines. We report a case of duodenal variceal bleeding secondary to portal vein stenosis in a 77-year-old woman receiving chemotherapy for unresectable perihilar cholangiocarcinoma. The patient presented with melena, nausea, vomiting and unstable vital signs suggestive of hemorrhagic shock. Emergency esophagogastroduodenoscopy revealed large nodular varices with a ruptured erosion on top in the superior duodenal angle, and variceal bleeding had stopped by the time of the procedure. Subsequent computed tomography showed the development of portosystemic collaterals; therefore, we performed percutaneous portal vein stent placement to reduce portal vein pressure. Since persistent bleeding was suspected, we also performed endoscopic injection sclerotherapy and achieved successful hemostasis with an improvement in liver function. This case revealed that a combination of portal vein stent placement and endoscopic injection sclerotherapy might be an effective therapy for duodenal variceal bleeding caused by portal vein stenosis.

Transjugular intrahepatic portosystemic shunt for repeated bleeding of hemorrhoids caused by severe portal hypertension with ectopic varices: A case report

Background

Severe portal hypertension is life-threatening and can bring adverse complications such as ascites, gastroesophageal varices, and edema. It can, even cause variceal hemorrhage, which may lead to a high risk of death. There is a rare incidence in bleeding of hemorrhoids caused by severe ectopic varices.

Case presentation

We report the case of a female patient with a 20-year history of hepatitis B virus infection who presented with repeated bleeding of hemorrhoids caused by severe portal hypertension with ectopic varices that is connection between the superior mesenteric vein and rectal venous plexus. Laboratory results revealed a hemoglobin level of 74 g/L. Finally, the patient was successfully treated with transjugular intrahepatic portosystemic shunt (TIPSS) placement without variceal embolization after a multidisciplinary comprehensive opinion. In the two-month follow-up period, the patient had failed to develop hepatic encephalopathy or hematochezia, and computed tomography venography (CTV) indicated that the stent was unobstructed and ascites disappeared.

Conclusions

TIPSS placement is effective for the case, and we hope this case can help improve clinicians’ awareness of hemorrhoidal bleeding with severe portal hypertension. Portal hypertension should also be considered during the diagnosis and treatment, as opposed to hemorrhoidal bleeding alone. Moreover, abdominal CTV is recommended as an effective imaging examination method to determine the stent status after operation.

A case of esophagojejunal varices rupture after proximal gastrectomy with double-tract reconstruction

BACKGROUND

The varices after proximal or total gastrectomy are uncommon because the supplying vessels are all divided. Emergent upper gastrointestinal endoscopy is the cornerstone of first-line management for the diagnosis and treatment of esophageal varices. However, there is no widely accepted standard strategy for esophagojejunal varices. We report a patient with esophagojejunal varices rupture 3 months after proximal gastrectomy treated with percutaneous transhepatic obliteration.

CASE PRESENTATION

A 50-year-old man who had undergone proximal gastrectomy with double-tract reconstruction for esophagogastric junctional cancer 3 months before was admitted to the hospital due to gastrointestinal perforation. We performed emergency surgery and abdominal symptoms and inflammatory response improved postoperative. However, on POD3, he had eruptive bleeding at the just anal side of esophagojejunal anastomosis. Endoscopic clipping was unsuccessful because the mucosa was fragile and easily lacerated. Contrast-enhanced CT scan revealed the dilatation of the jejunal vein flowing into the ascending jejunal limb. Therefore, he was diagnosed as esophagojejunal varices rupture and percutaneous transhepatic obliteration (PTO) was tried for hemostasis. The portal and superior mesenteric veins were catheterized with the percutaneous transhepatic approach. Contrast agent injection into the jejunal branch demonstrated retrograde flow to the azygos vein through esophagojejunal varices. The microcatheter was inserted into the variceal blood supply branch and 10 mL of 5% ethanolamine oleate with iopamidol was injected. After obliteration therapy, the superior mesenteric venogram showed complete occlusion of the variceal supply branch. The patient was discharged from the hospital without any complications after 14 days.

CONCLUSION

PTO can be effective for gastroesophageal varices rupture with a dilated jejunal vein of the ascending limb, few supplying vessels, and little ascites.

Duodenal Varix Rupture - A Rare Cause of Fatal Gastrointestinal Hemorrhage: A Case Report and Review of Literature

Duodenal varices are a rare complication of portal hypertension; with cirrhosis being the most common cause. Reports regarding the disease prognosis and natural history are limited. In addition to the diagnostic difficulty, ectopic duodenal varices pose a significant therapeutic challenge owing to the lack of specific management guidelines. Given the high risk of rupture, they can have devastating clinical outcomes. Rupture typically presents as a gastrointestinal hemorrhage and requires emergent interventions. We present a case of duodenal varix seen on upper endoscopy in a patient with portal hypertension and cirrhosis, together with review of the literature outlining the current understanding of this disease entity. We also highlight the pathogenetic mechanisms as well as the current diagnostic and therapeutic approaches for this potentially fatal disease.

[Life-threatening bleeding from ileal conduit venous varices in a patient with portal hypertension]

Life-threatening bleeding from portosystemic varices is a feared complication of portal hypertension. Particularly, varices in atypical locations-so-called ectopic varices-pose a challenge for diagnosis and therapy. In the present article, we describe the case of a patient with liver cirrhosis and recurrent bleeding from an ileal conduit resulting from peristomal varicosis. The difficult and hence delayed diagnosis led to a life-threatening hemorrhage that was successfully treated with interventional radiological variceal embolization and TIPS (transjugular intrahepatic portosystemic shunt) implantation.

Bleeding ectopic duodenal varix: use of a new microvascular plug (MVP) device along with transjugular intrahepatic portosystemic shunt (TIPSS)

Ectopic varices (ECV) occur along the gastrointestinal (GI) tract outside the common variceal sites and represent 2%-5% of all GI variceal bleeds with mortality rates up to 40%. Management is challenging because of inaccessibility and increased risk of rebleeding. We report what is to our knowledge the first clinical use of a new microvascular plug (MVP) with transjugular intrahepatic portosystemic shunt (TIPSS) for a bleeding duodenal varix (DV). A 68-year-old man presented with melena. Endoscopy demonstrated a grade II varix in the second part of the duodenum with red wale sign. TIPSS was performed and portogram revealed a single DV. Poststent placement venogram revealed a persistent varix and hence a 5-7 mm MVP was deployed. Subsequent imaging showed cessation of blood through the DV. The patient had no further bleeding. TIPSS with embolisation is an effective treatment for ECV. This MVP offers advantages due to its size and compatibility and can be redeployed in case of suboptimal placement.

Successful Management of Neobladder Variceal Bleeding

Hematuria from a neobladder can occur due to a variety of pathologies including tumors, stones, and fistulas. Variceal bleeding in a neobladder is a very rare condition with only one case reported in literature. We present a case of a patient with cirrhosis and portal hypertension and an ileocolic orthotopic neobladder presenting with hematuria. Computed tomographic angiography showed dilated varices around the neobladder which were successfully embolized. To the best of our knowledge, this is the first report case of variceal bleeding in a neobladder successfully managed with the combination of TIPS (transjugular intrahepatic portosystemic shunt) procedure and embolization.
