Jejunal variceal bleeding successfully treated with percutaneous coil embolization

Diagnosis and management of ectopic varices in portal hypertension

Ectopic variceal bleeding is a rare cause of gastrointestinal bleeding that can occur in settings of cirrhotic and non-cirrhotic portal hypertension and is characterised by its development at locations remote from the oesophagus and stomach. Ectopic varices can be difficult to identify and access, and, although a relatively uncommon cause of portal hypertensive bleeding, can represent a difficult diagnostic and therapeutic challenge associated with considerable mortality. Low incidence and variance in variceal anatomy preclude large randomised controlled trials, and clinical practice is based on experience from case reports, case series, and specialist centre expertise. Optimisation of survival outcomes relies on understanding a patient's portal venous anatomy and functional hepatic reserve to guide timely and targeted endoscopic and endovascular interventions to facilitate the rapid control of ectopic variceal bleeding.

A 55-Year-Old Man with Recurrent Gastrointestinal Bleeding Due to Stricture of the Portal Vein Anastomotic Site 12 Years After Combined Pancreas and Kidney Transplantation

BACKGROUND Varices of the upper gastrointestinal tract are due to portal hypertension and can result from occlusion of the portal venous system. This report is of a 55-year-old man with recurrent gastrointestinal bleeding due to stricture of the portal vein anastomotic site to inferior vena cava (IVC) 12 years after combined pancreas and kidney transplantation. CASE REPORT A 55-year-old man presented bleeding episodes requiring transfusion of more than 70 units of red blood cells (RBCs), complicated by bacterial and viral infection episodes including cytomegalovirus (CMV) reactivation and hepatitis E and transient impairment of function of the renal allograft. Endoscopy, computed tomography (CT) scan, and angiography revealed jejunal varices due to anastomotic stricture at the portal vein to IVC as the cause of the hemorrhage. Neither conservative therapy nor an anastomosis between the splenic vein of the graft and the internal iliac vein as a bypass could stop the life-threatening bleeding. During the recurrent bleeding, CD4 T lymphocytes were low, indicating immunodeficiency despite paused immunosuppressive therapy. After the hemorrhage resolved and immunosuppression was restarted, CD4 T lymphocyte levels normalized. Finally, to stop the hemorrhage and save the transplanted kidney and the patient's life, graft pancreatectomy was performed. Long-term damage to the renal transplant was not found. CONCLUSIONS This report is of a rare case of portal hypertension as a long-term complication of transplant surgery. Although acute venous thrombosis at the anastomotic site is a recognized postoperative complication of pancreatic transplant surgery, this case highlights the importance of post-transplant follow-up and diagnostic imaging.

Percutaneous transhepatic stent for chronic intestinal bleeding from jejunal varices in primary idiophatic superior mesenteric vein stenosis: A case report

Jejunal varices are a rare cause of gastrointestinal bleeding. In most cases, they are due to portal hypertension related to liver cirrhosis, less frequently to superior mesenteric vein stenosis (SMV). In this article we describe an unusual case of a 61 year-old male patient who arrived at our emergency department with intermittent variceal bleeding due to jejunal varices causing melena and subsequent chronic anaemia. Patient was indeed discovered to have primary idiopathic superior mesenteric vein stenosis. We managed to treat this patient via SMV stenting through percutaneous transhepatic approach. In cases of upper-GI bleed with negative endoscopy for active bleeding, a contrast-enhanced CT scan should be performed to diagnose jejunal varices and their underlying cause, such as SMV stenosis which is best treated with percutaneous phlebography.

Isolated ectopic jejunal varices in a patient with extrahepatic portal vein obstruction - A case report

Introduction and importance

Among the various causes for lower gastrointestinal bleeding, ectopic varices constitute a small chunk. Though rare, these can pose a diagnostic challenge with recurrent bleed leading to multiple admission and blood transfusions.

Case presentation

A 41-year-old male presented to our department with multiple episodes of melena. On further evaluation with CT angiography, a diagnosis of extrahepatic portal vein obstruction with moderate splenomegaly and ectopic jejunal varix was made. He underwent splenectomy with resection of involved jejunal segment with side to side anastomosis.

Clinical discussion

The diagnosis of ectopic varices remains elusive in a large number of cases in view of the varied etiology. Various newer endoscopic and imaging modalities can play a diagnostic as well as therapeutic role but this also further complicates the management as there is a lack of substantial guidelines directing the treatment protocol. As a result, we have to resort to a case by case approach for the optimal management in these cases.

Conclusion

The main modality of management for bleeding ectopic varices is percutaneous or endoscopic. Surgery is reserved for refractory cases, with decompressive shunts combined with segmental resection of involved intestine being at the forefront of surgical options.

•

Ectopic varices are an unusual cause of lower GI bleeding caused by porto-systemic collaterals.

•

Ectopic varices most commonly occur at jejuno-ileum, but duodenal varices are more prone to bleed.

•

The optimal management varies with each case due to paucity of treatment guidelines.

•

Decompressive shunt with splenectomy and segmental resection of intestine effectively prevents rebleeding.

Small Intestine Varices in Cirrhosis at a High-Volume Liver Transplant Center: A Retrospective Database Study and Literature Review

INTRODUCTION

Esophageal varices are a well-characterized sequela of portal hypertension; however, less is known about varices arising in ectopic locations. We aimed to describe bleeding small intestine varices (SIV) in patients with cirrhosis and compare characteristics and outcomes to published case reports.

METHODS

We performed an institutional chart review using billing codes and natural language processing between 2008 and 2019. Inclusion criteria were adult patients with cirrhosis and SIV verified by endoscopy, video capsule, or imaging. Patients with noncirrhotic portal hypertension and stomal varices were excluded. We examined demographic and clinical factors, characteristics of SIV, bleeding, intervention, and outcomes in our series and collated data from published cases identified during a literature review.

RESULTS

We identified 71 patients with cirrhosis and SIV (18 bled). The literature search yielded 76 cases with bleeding SIV. Our series and published cases were matched for age, sex, liver disease etiology, and SIV location. Length of stay and transfusion requirements were similar. Aggregate initial treatments (number, hemostasis rate) included medical (n = 7, 57%), endoscopic (n = 48, 56%), interventional radiology (n = 31, 77%), and surgery (n = 8, 87%). Hospital and overall mortality rates were higher in our series (22% and 38%) compared with the published cases (5.3% and 18.4%), respectively (P = 0.02 and P = 0.07).

DISCUSSION

A quarter of patients with cirrhosis and SIV experience bleeding, with high transfusion requirements, frequent need for secondary interventions, and high mortality. These findings highlight the need for a multidisciplinary approach and second-line therapeutic modalities in the timely management of bleeding SIV in cirrhosis.

Jejunal varices as a rare cause of recurrent gastrointestinal bleeding in a 74-year-old man with extrahepatic portal hypertension after pancreato-biliary surgery

A 74-year-old man presented to our hospital with recurrent lower gastrointestinal bleeding. His past medical history was remarkable for a duodenal papilla carcinoma and he underwent a pylorus-preserving pancreaticoduodenectomy 4 years before. During diagnostic work-up a severe portal vein stenosis after surgery and multiple dilated intramural jejunal varices, which formed as collateral pathways could be detected. Based on these findings, the recurrent haemorrhages were considered to be due to repeated rupturing and bleeding of jejunal varices. Therapeutically, the portal vein stenosis was treated with endovascular stent placement leading to a reduction in prestenotic portal pressure. During follow-up no further episodes of gastrointestinal bleeding were observed. Bleeding from jejunal varices is a very rare cause of gastrointestinal haemorrhages and represents a diagnostic and therapeutic challenge. However, it should be considered in differential diagnosis of obscure recurrent gastrointestinal haemorrhages in patients with a history of hepato-pancreato-biliary surgery.

Jejunal varices: an unconsidered cause of recurrent gastrointestinal haemorrhage

A 78-year-old woman presented with melaenic stool and severe anaemia 4 years after a pancreaticoduodenectomy for adenocarcinoma of the pancreas. Initial workup revealed haemorrhage from the choledochojejunostomy site. Despite multiple endoscopic clips to the region, bleeding reoccurred multiple times over a period of several months. Due to ongoing haemorrhage, her case was urgently presented at the hospital's multidisciplinary hepatobiliary conference. The contrast-enhanced abdominal CT revealed severe stenosis of the extrahepatic portal vein and large afferent jejunal varices at the choledochojejunostomy, suspected as the cause of her persistent bleed. The recommendation was a percutaneous transhepatic approach for stenting of the portal vein stenosis that resulted in rapid decompression of the jejunal varices and control of her haemorrhage.

Mucosal Changes in the Small Intestines in Portal Hypertension: First Study Using the Pillcam SB3 Capsule Endoscopy System

BACKGROUND/AIMS

To evaluate patients with portal hypertension (PH) of varied etiologies for portal hypertensive enteropathy (PHE) using the PillCam SB3 capsule endoscopy (CE) system.

METHODS

Consecutive patients with PH presenting with unexplained anemia and/or occult gastrointestinal bleeding were evaluated using the PillCam SB3 CE system. Abnormal findings were categorized as vascular or non-vascular. The patients with ongoing bleeding caused by PHE were treated. The correlation of the CE scores of PHE with the clinical, laboratory, and endoscopic features was determined.

RESULTS

Of the 43 patients included in the study, 41 (95.3%) showed PHE findings. These included varices (67.4%), red spots (60.5%), erythema (44.2%), villous edema (46.5%), telangiectasia (16.3%), and polyps (16.3%). The CE scores varied from 0 to 8 (mean±standard deviation, 4.09±1.8). Five patients (11.6%) showed evidence of ongoing or recent bleeding due to PHE. Three of these five patients underwent endotherapy, and one patient underwent radiological coil placement.

CONCLUSION

The PillCam SB3 CE system revealed a high prevalence of PHE in the patients with PH. Using this system, evidence of bleeding due to PHE was found in a small but definite proportion of the patients.

Diagnostic and therapeutic features of small bowel involvement in portal hypertension

Enteropathy is a lesser known complication of portal hypertension and consists of different changes in the mucosal layer of the small bowel which lead to the appearance of vascular and inflammatory lesions. It can be an important co-factor in the development of anemia in the cirrhotic population, and nowadays an easy and non-invasive diagnosis can be made thanks to capsule endoscopy. However, it is rarely considered in the management of patients with portal hypertension. Some aspects such as pathogenesis or incidence remain unclear and no specific recommendations are included in the guidelines regarding diagnosis or treatment. A review of the available literature was performed with regards to the most relevant aspects of this entity.

Laparotomy-Assisted Endoscopic Injection of Jejunal Varices for Overt Small Bowel Bleeding

A 54-year old male liver transplant recipient with Roux-en-Y choledochojejunostomy was admitted for symptomatic anemia. Despite endoscopies and a bleeding scan, active bleeding was not visualized. Angiography and abdominal computed tomography demonstrated possible jejunal varices at the choledochojejunal anastomosis. Double-balloon enteroscopy demonstrated varices with overlying clots in the Roux limb at the anastomosis. Due to the extensive loop formation and unstable position of the endoscope, therapeutic intervention could not be performed. Operative enterotomy and intraoperative endoscopy were subsequently required. A varix in the jejunum with venous flow on Doppler was injected twice with cyanoacrylate and successfully obturated.

[Surgical Removal of Migrated Coil after Embolization of Jejunal Variceal Bleeding: A Case Report]

Jejunal variceal bleeding is less common compared with esophagogastric varices in patients with portal hypertension. However, jejunal variceal bleeding can be fatal without treatment. Treatments include surgery, transjugular intrahepatic porto-systemic shunt (TIPS), endoscopic sclerotherapy, percutaneous coil embolization, and balloon-occluded retrograde transvenous obliteration (BRTO). Percutaneous coil embolization can be considered as an alternative treatment option for those where endoscopic sclerotherapy, surgery, TIPS or BRTO are not possible. Complications of percutaneous coil embolization have been reported, including coil migration. Herein, we report a case of migration of the coil into the jejunal lumen after percutaneous coil embolization for jejunal variceal bleeding. The migrated coil was successfully removed using surgery.

Capsule Endoscopy for Portal Hypertensive Enteropathy

Portal hypertensive enteropathy (PHE) is a mucosal abnormality of the small bowel that is observed in patients with portal hypertension (PH) and can lead to gastrointestinal bleeding and anemia. The pathogenesis is still not completely understood. The introduction of new endoscopic methods, including capsule endoscopy (CE) or balloon-assisted enteroscopy, has increased the detection of these abnormalities. CE can also serve as a road map for deciding subsequent interventions and evaluating the treatment effect. The prevalence of PHE is reportedly 40-70% in patients with PH. Endoscopic findings can be roughly divided into vascular and nonvascular lesions such as inflammatory-like lesions. Traditionally, PHE-associated factors include large esophageal varices, portal hypertensive gastropathy or colopathy, Child-Turcotte-Pugh class B or C, a history of variceal treatment, and acute gastrointestinal bleeding. More recently, on using scoring systems, a high computed tomography or transient elastography score was reportedly PHE-related factors. However, the prevalence of PHE and its related associated factors remain controversial. The management of PHE has not yet been standardized. It should be individualized according to each patient's situation, the availability of therapy, and each institutional expertise.

Ectopic Jejunal Variceal Rupture in a Liver Transplant Recipient Successfully Treated With Percutaneous Transhepatic Coil Embolization: A Case Report

Here we present the rupture of ectopic jejunal varices developing in a liver transplant recipient without portal hypertension, which was successfully treated with percutaneous transhepatic coil embolization.A 48-year-old man with massive melena was admitted to our department. He had undergone liver transplantation for hepatitis B virus-related liver cirrhosis 8 months before, and his postoperative course was satisfactory except for an acute cellular rejection. No evidence of bleeding was detected by upper endoscopy or colonoscopy, but dynamic multidetector computed tomography of the whole abdomen revealed an intestinal varix protruding into the lumen of the jejunum with suspected extravasation. There was no evidence of portal venous stenosis or thrombosis. Immediately upon diagnosis of the ruptured ectopic jejunal varix, percutaneous transhepatic coil embolization was performed, achieving complete hemostasis. The portal venous pressure measured during the procedure was within normal limits. He was discharged from the hospital 11 days after embolization and remained in stable condition without re-bleeding 6 months after discharge.This is the first report of an ectopic intestinal variceal rupture in an uneventful liver transplant recipient that was successfully treated with interventional percutaneous transhepatic coil embolization. Clinicians encountering liver transplant recipients with melena should be aware of the possibility of late-onset rupture of ectopic varices, even in those having an uneventful post-transplant course without portal hypertension.

Portal hypertensive enteropathy

Portal hypertensive enteropathy (PHE) is a condition that describes the pathologic changes and mucosal abnormalities observed in the small intestine of patients with portal hypertension. This entity is being increasingly recognized and better understood over the past decade due to increased accessibility of the small intestine made possible by the introduction of video capsule endoscopy and deep enteroscopy. Though challenged by its diverse endoscopic appearance, multiple scoring systems have been proposed to classify the endoscopic presentation and grade its severity. Endoscopic findings can be broadly categorized into vascular and non-vascular lesions with many subtypes of both categories. Clinical manifestations of PHE can range from asymptomatic incidental findings to fatal gastrointestinal hemorrhage. Classic endoscopic findings in the setting of portal hypertension may lead to a prompt diagnosis. Occasionally histopathology and cross sectional imaging like computed tomography or magnetic resonance imaging may be helpful in establishing a diagnosis. Management of overt bleeding requires multidisciplinary approach involving hepatologists, endoscopists, surgeons, and interventional radiologists. Adequate resuscitation, reduction of portal pressure, and endoscopic therapeutic intervention remain the main principles of the initial treatment. This article reviews the existing evidence on PHE with emphasis on its classification, diagnosis, clinical manifestations, endoscopic appearance, pathological findings, and clinical management. A new schematic management of ectopic variceal bleed is also proposed.

Successful percutaneous angioembolisation of bleeding jejunal varix by acrylate glue and coils

Portal hypertension is a common disease worldwide. One of its rare complications is bleeding jejunal varices which is usually asymptomatic and may present with gastrointestinal bleeding. We present a case of a jejunal bleeding that was successfully embolised with acrylate glue and embolisation coils. A middle-aged woman with a history of multiple abdominal surgeries for adenocarcinoma of right ovary, presented to us with multiple episodes of haematochezia. On a CT scan of the abdomen, she was diagnosed with chronic liver disease with portal hypertension, multiple varices at porto-systemic anastomosis and ectopic jejunal varix. She was treated by interventional radiologists by percutaneous embolisation of bleeding varix using glue and embolisation coils through a portal venous approach.

Percutaneous transhepatic sclerotherapy for recurrent bleeding ileal varices diagnosed by capsule endoscopy and computed tomography during percutaneous transhepatic venography

We report a case of acute uncontrolled gastrointestinal bleeding in a patient with liver cirrhosis. A 64-year-old man was admitted to our hospital for further investigation of blood in stools. Preliminary examination by computed tomography (CT) as well as upper and lower endoscopy could not detect the bleeding source. Exploratory laparotomy was considered difficult due to potential easy bleeding and adhesions caused by past abdominal surgery. The hemoglobin level was normalized by blood transfusion. Capsule endoscopy (CE) identified ileal varices. The top of these ileal varices was red, prompting their identification as the source of bleeding. Percutaneous transhepatic venography (PTV) confirmed the presence of many varices in the branch of the superior mesenteric vein, although the bleeding source could not be identified. CT during PTV identified varices protruding into the ileal lumen, which were managed subsequently by percutaneous transhepatic sclerotherapy (PTS). The procedure stopped the bleeding completely. CE proved less invasive and effective in detecting obscure gastrointestinal bleeding. CT during PTV followed by PTS is suitable for diagnosis and treatment of bleeding varices in patients with portal hypertension.

Massive gastrointestinal bleeding due to isolated jejunal varices in a patient without portal hypertension

INTRODUCTION

Isolated ectopic varices located in the small bowel are uncommon. Portal hypertension caused by liver cirrhosis is the most common predisposing risk factor.

PRESENTATION OF CASE

We present an unusual case of massive gastrointestinal bleeding from idiopathic jejunal varices in a 73-year-old Caucasian male without portal hypertension. Exploratory laparotomy disclosed ectopic varices located in the small intestine. Segmental resection of the jejunum with end to end anastomosis resulted in a complete resolution of the haemorrhage. During a 5 year follow up, the patient is stable with no bleeding recurrence.

DISCUSSION

Information on aetiology, diagnosis and management of jejunal varices is reviewed.

CONCLUSION

Diagnosis and management of isolated jejunal varices is challenging. Surgeons as well as acute care physicians have to consider idiopatic form of jejunal varices as a potential cause of gastrointestinal bleeding when gastroduodenoscopy and colonoscopy are negative.
