Successful Treatment of a Case of Ectopic Jejunal Varices with Portal Venous Stenting

Outcomes of endoscopic sclerotherapy for jejunal varices at the site of choledochojejunostomy (with video): Three case reports

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.

CASE SUMMARY

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.

CONCLUSION

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.

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.

Portal vein stenting in the management of duodenal varices due to malignant obstruction: A case report and literature review

INTRODUCTION AND IMPORTANCE

Ectopic varices of the small bowel are a rare complication of portal hypertension. There are various aetiologies that can cause portal vein hypertension such as portal vein obstruction. Each of these pathologies has their own management strategies. Currently, there is a paucity of literature demonstrating the best management for patients with malignant portal vein obstruction leading to these varices.

CASE PRESENTATION

This report presents a case of a 66-year-old female who presented with recurrent per-rectal bleeding. Computed tomography angiography diagnosed duodenal varices in the context of malignant obstruction of the portal vein. Due to being a poor operative candidate, she underwent trans-hepatic portal vein stenting leading to resolution of her symptoms.

CLINICAL DISCUSSION

To date, the management of portal vein obstruction due to various aetiologies has only been reported in case reports with no significant large-scale studies providing recommendations on the most appropriate treatment. This case demonstrates the role of palliative stenting for patients with portal hypertension due to malignant portal vein obstruction.

CONCLUSION

Duodenal varices are a rare complication of portal vein obstruction. This article contributes to the literature by demonstrating that patients with complications associated with portal vein obstruction can benefit from stenting. For those with malignant obstruction, palliative stenting serves as an important therapeutic option.

Laparotomy-assisted transcatheter variceal embolization for bleeding jejunal varices formed at the site of choledochojejunostomy: Report of a case and review of the literature

•

Jejunal varices should be included in the differential diagnosis of melena in patients with a bilioenteric anastomosis and portal vein hypertension.

•

Laparotomy-assisted transcatheter variceal embolization is one of the options for the treatment of jejunal varices.

•

A multidisciplinary approach is critical for timely management of the unstable patient with bleeding from jejunal varices.

Introduction

Bleeding from jejunal varices formed at the site of a bilioenteric anastomosis due to portal vein hypertension is relatively rare and difficult to treat.

Presentation of case

An 80-year-old man with melena, slight fever, and abdominal pain was referred to our hospital. He had undergone subtotal stomach-preserving pancreaticoduodenectomy for cancer of the ampulla of Vater six years earlier. Follow-up computed tomography (CT) three years earlier showed occlusion of the extrahepatic portal vein and the growth of collateral flow into the lateral segment of the liver, but there were no signs of recurrence of the cancer of the ampulla of Vater. The patient underwent prophylactic endoscopic variceal ligation for esophageal varices one year earlier. On admission, blood tests showed anemia and elevated liver enzyme and bilirubin levels. Esophagogastroduodenoscopy and colonoscopy failed to identify the site of bleeding. Double-balloon endoscopy showed the dilated blood vessels around the stenotic anastomosis of the choledochojejunostomy. A CT scan was consistent with total occlusion of the portal vein and varices around the choledochojejunostomy site. With a diagnosis of jejunal varices, laparotomy-assisted transcatheter variceal embolization was performed. Double-balloon endoscopy performed one month after laparotomy-assisted transcatheter variceal embolization showed no varices, and dilation of the stenotic anastomosis of the choledochojejunostomy was performed safely.

Conclusion

Jejunal varices should be included in the differential diagnosis of melena in patients with a previous history of surgery with a bilioenteric anastomosis and portal vein hypertension. Laparotomy-assisted transcatheter variceal embolization is one of the options for the treatment of jejunal varices.
