Ectopic gastrointestinal variceal bleeding with portal hypertension

New sights in ectopic varices in portal hypertension

Ectopic varices and associated bleeding, although rare, pose a significant risk to patients with portal hypertension, carrying a relatively high mortality rate. These varices can occur in various anatomical regions, excluding the gastroesophageal region, which is typically associated with portal vein drainage. The limited data available in the literature, derived mostly from case reports and series, make the diagnosis and treatment of ectopic variceal bleeding particularly challenging. Furthermore, it is crucial to recognize that ectopic varices in different sites can exhibit variations in key decision-making factors such as aetiology and vascular anatomy, severity and bleeding risk and hepatic reserve. These factors significantly influence treatment strategies and underscore the importance of adopting individualized management approaches. Therefore, the objective of this review is to provide a comprehensive overview of the fundamental knowledge surrounding ectopic varices and to propose site-oriented, stepwise diagnosis and treatment algorithms for this complex clinical issue. A multidisciplinary treatment approach is strongly recommended in managing ectopic varices. In addition, to enhance clinical reference, we have included typical case reports of ectopic varices in various sites in our review, while being mindful of potential publication bias.

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.

Incidence, risk factors, and outcomes of jejunal varix of the afferent loop after pancreatoduodenectomy

BACKGROUND

Jejunal varix is a concerning late complication after pancreatoduodenectomy (PD) due to the risk of recurrent and intractable bleeding. Our aim was to investigate the incidence, risk factors, and outcomes of jejunal varix after PD.

METHODS

A total of 709 patients who underwent PD between 2007 and 2017 were included. Preoperative and postoperative CT images were reviewed to evaluate the development of portal vein (PV) stenosis (≥50%) and jejunal varices.

RESULTS

Jejunal varix developed in 83 (11.7%) patients at a median of 12 months after PD. Eighteen (21.7%) patients experienced variceal bleeding. PV stenosis (P < 0.001; odds ratio [OR] 33.2, 95% confidence interval [CI] 15.6-66.7) and PV/superior mesenteric vein resection (P = 0.028; OR 2.3, 95% CI 1.1-4.7) were independent risk factors for jejunal varix. Of the nine patients who underwent stent placement for PV stenosis before the formation of jejunal varices, none experienced variceal bleeding. By contrast, 18 (27.3%) of the 135 patients without PV stent placement experienced at least one episode of variceal bleeding.

CONCLUSIONS

The incidence of jejunal varix was substantial after PD. PV stenosis was a strong risk factor for jejunal varix. Early PV stent placement and maintaining stent patency could reduce the risk of variceal bleeding in patients with PV stenosis.

Recurrent Ileal Variceal Bleeding as a Diagnostic and Therapeutic Challenge

Introduction

Massive ileal variceal bleeding is a rare intricate condition that needs rapid management and treatment. The absence of randomized clinical trials in this field leads to a lack of evidence-based diagnostic and therapeutical approaches. We present a case report describing imaging, endoscopic, and surgical procedures leading to the diagnosis and resolution of severe ileal variceal bleeding. Case Report. We admitted a 63-year-old patient for recurrent anemia and ongoing bleeding from the gastrointestinal tract presenting as enterorrhagia. We were not able to elucidate the source by endoscopic, angiographic, or nuclear imaging methods. As a last resort, we carried out a surgical procedure with peroperative enteroscopy and subsequent resection of the affected part of the intestine.

Conclusion

We present a patient with a case of ileal variceal bleeding, which required extensive diagnostic and therapeutic effort with a unique peroperative enteroscopic approach.

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.

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.
