Splenic and perisplenic involvement in acute pancreatitis: determination of prevalence and morphologic helical CT features

Splenic hematoma following acute pancreatitis, and the role of conservative management: A case report

Key clinical message

We reported a unique case in which the patient developed splenic hematoma following acute pancreatitis, the condition responded well to conservative management without any surgical intervention.

Abstract

Splenic hematoma following acute pancreatitis is a rare complication that is thought to be due to the distribution of pancreatic exudates to the spleen. We presented a case of a 44-year-old patient with acute pancreatitis who developed a splenic hematoma. He responded well to conservative management and the hematoma was resolved.

Tuftsin ameliorates splenic inflammatory injury by promoting neuropilin-1 in severe acute pancreatitis

Severe acute pancreatitis (SAP)-associated spleen injury causing immune disturbances aggravates organs injuries, which contributes to higher mortality rate. However, there are no effective drugs to cure SAP-induced spleen injury. Here, we found that Tuftsin (TN) is effective for ameliorating SAP-induced pathological damage and inflammation of spleen, mainly via alleviating mitochondrial dysfunction, oxidative stress, ATP depletion and the expression of pro-inflammatory factors. We further found that TN promoted anti-inflammatory macrophage phenotype M2 via up-regulating NRP1 on macrophage in spleen during SAP. Meanwhile, EG00229 (an inhibitor of NRP1 bound to TN) weakened TN's therapeutic effect in SAP-associated spleen injury. And EG00229 also inhibited M2 macrophage, leading to increasing inflammasome formation. Additionally, EG00229 reduced the protective efficiency of TN on mitochondrial dysfunction, and inflammation injury via NRP1 in spleen caused by SAP. Similarly, siRNA-Nrp1 into macrophage also prevented TN's inhibition on apoptosis. These findings reveal that TN alleviates SAP-induced spleen injury by promoting NRP1.

Association of Atraumatic Splenic Rupture and Acute Pancreatitis: Case Report with Literature Review

Atraumatic splenic rupture is an uncommon complication of acute pancreatitis. This article presents a case of a 35-year-old patient presenting with acute pancreatitis who subsequently developed a splenic vein thrombosis and splenic rupture requiring a laparotomy and splenectomy. This rare but life-threatening complication requires prompt recognition and management in patients with pancreatitis who develop sudden hemodynamic instability.

Activation of TLR4 induces severe acute pancreatitis-associated spleen injury via ROS-disrupted mitophagy pathway

Severe acute pancreatitis (SAP) is complicated by systemic inflammatory response syndrome and multiple organ dysfunction, the disease will eventually result in death in almost half of the case. The spleen, as the largest immune organ adjacent to the pancreas, is prone to damage in SAP, thereby aggravating the damage of other organs and increasing mortality. However, to date, the research on the mechanism and treatment of spleen injury caused by SAP is still in its infancy. Herein, we investigated the mechanism of spleen injury, and explored the application potential of tuftsin for relieving spleen damage in SAP mice. Firstly, SAP mice model was constructed via the retrograde infusion of 3.5 % sodium taurocholate into the biliopancreatic duct. Then, we proved that the up-regulation of Toll-like receptor 4 (TLR4) in spleen would lead to the accumulation of reactive oxygen species (ROS) and mitochondrial dysfunction under SAP conditions. The splenic ROS and mitochondrial dysfunction could be improved by N-acetylcysteine (NAC) treatment or knocking out TLR4 in SAP mice. Meanwhile, we found that NAC treatment could also improve the autophagy of spleen tissue, suggesting that splenic ROS may affect impaired autophagy, causing the accumulation of damaged mitochondria, aggravating spleen damage. Furthermore, we verified the mechanism of spleen injury is caused by splenic ROS affecting PI3K/p-AKT/mTOR pathway-mediated autophagy. In addition, we detected the spleen injury caused by SAP could decrease the concentration of tuftsin in the serum of mice. Whereas, exogenous supplementation of tuftsin ameliorated the pathological damage, ROS accumulation, impaired autophagy, inflammation expression and apoptosis in damaged spleen. In summary, we verified the new mechanism of SAP-caused spleen damage that TLR4-induced ROS provoked mitophagy impairment and mitochondrial dysfunction in spleen via PI3K/p-AKT mTOR signaling, and the application potential of tuftsin in treating spleen injury, which might expand novel ideas and methods for the treatment of pancreatitis.

Evaluation of Platelet Indices in Patients with Splanchnic Vein Thrombosis

Splanchnic vein thrombosis (SVT) is a rare and lethal form of venous thrombosis. The role of platelet indices (PI's) is not well studied in SVT. The present study was aimed to assess if the PI's have a significant association with SVT. This was a prospective case control study from coagulation laboratory of Hematology department. A total 100 cases of SVT and 80 controls were screened for PI's (MPV, PCT & PDW) and platelet count (PC) along with routine thrombophilic risk factors. The SVT cases were divided into 3 subgroups, that comprised of EHPVO/ PVT (n = 69), BCS (n = 27), and MVT (n = 4). The mean PC and PCT were significantly lower in patients than the controls. The PDW was significantly higher in cases than in the controls and MPV was relatively higher in cases however did not show statistical significance. In addition, 16 patients were found to have deranged thrombophilic risk factors. Among these, 8 cases had inherited risk factors (2: FVL; 5: PC; 1: PS) and 8 cases had acquired risk factors (2: APL; and 5: multiple factors and one case had both FVL mutation and APL positivity). The PDW and PCT together with PC were found to significantly differ in SVT cases than in controls, particularly in idiopathic cases. It may be worthwhile to explore the utility of PI's as a potential risk factor in SVT.

Contrast-enhanced ultrasound of the spleen, pancreas and gallbladder in children

Gray-scale and color/power Doppler ultrasound (US) are the first-line imaging modalities to evaluate the spleen, gallbladder and pancreas in children. The increasing use of contrast-enhanced ultrasound (CEUS) as a reliable and safe method to evaluate liver lesions in the pediatric population promises potential for imaging other internal organs. Although CEUS applications of the spleen, gallbladder and pancreas have been well described in adults, they have not been fully explored in children. In this manuscript, we present an overview of the applications of CEUS for normal variants and diseases affecting the spleen, gallbladder and pancreas. We highlight a variety of cases as examples of how CEUS can serve in the diagnosis and follow-up for such diseases in children. Our discussion includes specific examination techniques; presentation of the main imaging findings in various benign and malignant lesions of the spleen, gallbladder and pancreas in children; and acknowledgment of the limitations of CEUS for these organs.

Unusual Sites of Necrotic Collections in Acute Necrotizing Pancreatitis: Association with Parenchymal Necrosis and Clinical Outcomes

BACKGROUND

The presence of necrotic collection in acute necrotizing pancreatitis (ANP) at intra-abdominal sites other than the retroperitoneum has not been systematically studied.

AIM

To investigate unusual sites of necrotic collections at computed tomography (CT) and to evaluate association with pancreatic necrosis and clinical outcomes.

METHODS

This retrospective study comprised of consecutive patients with ANP evaluated between January 2018 and March 2019. Based on CT findings, patients were divided into two groups: collections at unusual sites (small bowel mesentery, mesocolon, omentum, subcapsular collections along liver and spleen, pelvis, anterior abdominal wall, and inguinoscrotal regions) and collections at usual retroperitoneal locations (lesser sac, gastrosplenic location, anterior and posterior pararenal spaces, and paracolic gutters). The differences in CT findings and clinical outcomes (need for drainage, length of hospitalization, intensive care unit admission, surgery, and death) between the two groups were evaluated.

RESULTS

A total of 75 patients with ANP were evaluated. There were 25 (33.3%) patients with collections in unusual locations. These included mesentery (n = 17), splenic subcapsular location (n = 7), omentum (n = 6), hepatic subcapsular location (n = 4), anterior abdominal wall (n = 3), pelvis (n = 2), and inguinoscrotal location (n = 1). Compared to patients with collections at usual locations (n = 50), there were no differences in the CT findings except complete parenchymal necrosis (32% vs. 0%, P = .001). There were no statistically significant differences in the clinical outcomes between the two groups.

CONCLUSIONS

Mesenteric collections are frequent in ANP. The other non-retroperitoneal sites are infrequently involved. There is no association between unusual sites of collection and clinical outcomes.

Acute Pancreatitis Induced Splenic Vein Thrombosis

Acute inflammation of the pancreas, known as pancreatitis, can result in many complications ranging from acute distress respiratory syndrome to pancreatic necrosis. A relatively common vascular complication of pancreatitis is splenic vein thrombosis (SVT) due to intimal inflammation leading to platelet aggregation and thrombosis. The management of SVT with regard to anticoagulation (AC) might appear to be perplexing at first given the recommendation to withhold any sort of AC. Research studies have shown that these patients have an increased risk of gastrointestinal bleeding without AC. In this report, we discuss a case of hypertriglyceridemia-induced pancreatitis. During hospitalization, our patient complained of worsening abdominal pain with objective fevers and leukocytosis in which CT scan of the abdomen was significant for hemorrhagic pancreatitis with necrosis, acute SVT, and splenomegaly. The patient was managed conservatively with IV fluids, pain relief medications, and antibiotics. 

A review of anatomy, pathology, and disease spread in the perisplenic region

The perisplenic region is a complex anatomical area involving multiple peritoneal and subperitoneal structures, which influence the presentation and behavior of various pathologic processes. This review is a comprehensive resource for perisplenic anatomy and pathology with associated clinical presentations and imaging findings. Understanding the pathophysiologic intricacies of the perisplenic region assists the radiologist in building a helpful differential diagnosis and recognizing predictable disease patterns.

Atraumatic Splenic Hemorrhage as a Rare Complication of Pancreatitis: Case Report and Literature Review

Splenic hemorrhage (hematoma and rupture) is a rare complication of pancreatitis. In this article, we present a rare case of spontaneous splenic rupture as a complication of acute pancreatitis. A literature review was also completed to describe the patient characteristics, associated pancreatitis etiology, clinical presentations, risk factors, diagnostic and treatment modalities, and outcomes.

[Abdominal pain and signs of acute pancreatitis in a 60-year-old man]

Spontaneous splenic rupture is an uncommon complication of acute pancreatitis. This report describes the case of a 60-year-old man with acute pancreatitis complicated by splenic rupture. The patient was admitted to the emergency department with pain in the upper abdomen that had been present for 2 days. He was diagnosed with acute pancreatitis of alcoholic etiology. The patient was admitted to the hospital for two recurrent episodes in the last 4 months of acute pancreatitis of alcoholic etiology. Magnetic resonance imaging of the abdomen revealed a suspicious area of necrosis. Seventy-two hours after admission, the patient had significant improvement in symptoms and the inflammation markers rapidly decreased. However, he showed clinical worsening on the seventh day of hospitalization, with increasing abdominal distension and reduced hemoglobin levels. A CT angiography showed a large amount of free fluid in the abdominal cavity, along with a large splenic hematoma. The patient subsequently underwent laparotomy, which showed hemoperitoneum due to rupture of the splenic parenchyma. A splenectomy was performed with resection of the pancreatic tail.

Gastric varices and splenic vein obstruction during steroid treatment for autoimmune pancreatitis: A case report and literature review

RATIONALE

Few cases of autoimmune pancreatitis (AIP) complicated by gastric varices, in the absence of splenic vein obstruction, have been described in the medical literature. The findings in this case parallel those of 3 previously described cases from Japan and support a pathologic explanation for the evolution of gastric varices in relation to early splenomegaly and the role of steroid therapy for AIP.

PATIENT CONCERNS

A 50-year-old male with a history of transfusion-requiring erosive gastritis and recently diagnosed AIP on steroid therapy for 2 weeks presented with a 2-day history of lightheadedness, abdominal pain, and melena.

DIAGNOSIS

Esophagogastroduodenoscopy (EGD) revealed prominent varices in the gastric fundus. An abdominal ultrasound with Doppler demonstrated patency of the splenic, hepatic, and portal veins. Review of previous imaging revealed that the splenic vein and the superior mesenteric vein (SMV) were occluded prior to the diagnosis of AIP and steroid therapy initiation.

OUTCOME

Following resolution of hemodynamic instability through fluid resuscitation and blood transfusion, the remainder of his hospital course was uneventful. Subsequent to discontinuation of steroid therapy, he developed near total reocclusion of both the splenic vein and SMV.

LESSON

Early steroid treatment should be considered in patients with uncomplicated AIP to prevent the occlusive vascular complications that are frequently associated with the pathophysiology of this disease process.

Accuracy of contrast-enhanced ultrasound compared with conventional ultrasound in acute pancreatitis: Diagnosis and complication monitoring

Contrast-enhanced ultrasound (CEUS) has been used for diagnosing acute pancreatitis (AP), particularly severe acute pancreatitis (SAP). However, the diagnostic difference between CEUS and conventional ultrasonography (CUS) for AP and SAP has not been reported. The aim of the present study was to investigate the diagnostic accuracy of CUS and CEUS for AP. A total of 196 patients clinically diagnosed with AP were selected. All patients underwent CUS, CEUS and contrast-enhanced computed tomography (CECT) within 72 h. CECT was considered the gold standard. Pancreatic size, peripancreatic fluid collection (PPFC) and splenic vessel complications were the variables observed by CUS and CEUS. The differences in the variables among the three methods were analyzed using the χ² test and statistical analysis software. Significant differences in pancreatic size, PPFC and splenic vessel complications in AP were observed between CEUS and CUS (P<0.05). χ² test results indicated that CEUS significantly differed from CUS in terms of having a higher diagnostic accuracy for AP and SAP (P<0.05). The results indicate that CEUS is a reliable method for the diagnosis and monitoring of AP and SAP, and may be substituted for CECT.

Endoscopic management of splenic pseudocysts associated with acute and chronic pancreatitis

Background

Splenic pseudocysts (SP) are a rare consequence of both acute and chronic pancreatitis. Surgery has been conventional treatment for SP and literature on role of endoscopic treatment is scant. In this study, we retrospectively evaluated SP clinical and radiological characteristics as well as the outcome following endoscopic drainage.

Methods

Retrospective analysis of SP patients seen at our unit from January 2002 to June 2015. All patients were treated with attempted endoscopic transpapillary drainage with a nasopancreatic drain or stent. Patients not responding underwent endoscopic ultrasound-guided transmural or percutaneous radiological drainage.

Results

Eleven patients with SP (all male; mean age: 40.5±8.8 years) were studied. Seven patients had chronic pancreatitis and 4 patients had SP following acute pancreatitis. The majority (10/11; 91%) had alcohol-related acute or chronic pancreatitis with one patient having coexistent pancreas divisum. Seven (64%) patients were treated successfully with transpapillary drainage only; one (9%) patient needed combined transpapillary and transmural drainage; and 3 (27%) patients needed surgery.

Conclusion

Endoscopic transpapillary drainage is an effective treatment for SP especially when it is not infected and with clear contents, and is associated with partial ductal disruption that can be bridged by an endoprosthesis.

Prevalence of Splanchnic Vein Thrombosis in Pancreatitis: A Systematic Review and Meta-Analysis of Observational Studies

Splanchnic vein thrombosis (SVT) may be negatively associated with the prognosis of pancreatitis. We performed a systematic review and meta-analysis of literatures to explore the prevalence of SVT in pancreatitis. All observational studies regarding the prevalence of SVT in pancreatitis were identified via PubMed and EMBASE databases. The prevalence of SVT was pooled in the total of patients with pancreatitis. And it was also pooled in the subgroup analyses according to the stage and causes of pancreatitis, location of SVT, and regions where the studies were performed. After the review of 714 studies, 44 studies fulfilled the inclusion criteria. Meta-analyses showed a pooled prevalence of SVT of 13.6% in pancreatitis. According to the stage of pancreatitis, the pooled prevalence of SVT was 16.6% and 11.6% in patients with acute and chronic pancreatitis, respectively. According to the causes of pancreatitis, the pooled prevalence of SVT was 12.2% and 14.6% in patients with hereditary and autoimmune pancreatitis. According to the location of SVT, the pooled prevalence of portal vein, splenic vein, and mesenteric vein thrombosis was 6.2%, 11.2%, and 2.7% in pancreatitis. The prevalence of SVT in pancreatitis was 16.9%, 11.5%, and 8.5% in Europe, America, and Asia, respectively.

Consensus guidelines on severe acute pancreatitis

This Position Paper contains clinically oriented guidelines by the Italian Association for the Study of the Pancreas (AISP) for the diagnosis and treatment of severe acute pancreatitis. The statements were formulated by three working groups of experts who searched and analysed the most recent literature; a consensus process was then performed using a modified Delphi procedure. The statements provide recommendations on the most appropriate definition of the complications of severe acute pancreatitis, the diagnostic approach and the timing of conservative as well as interventional endoscopic, radiological and surgical treatments.

The revised Atlanta classification for acute pancreatitis: a CT imaging guide for radiologists

Accurate diagnosis and description of the various findings in acute pancreatitis is important for treatment. The original Atlanta classification for acute pancreatitis sought to create a uniform system for classifying the severity of acute pancreatitis as well as common language to describe the various events that can occur in acute pancreatitis. The goal was to allow accurate communication between physicians using standardized language so correct treatment options could be used. Since that time, advances in the understanding of acute pancreatitis as well as improvements in both interventions and imaging have led to criticisms of the system and its abandonment by physicians. A 2007 revision of the Atlanta classifications sought to address many of these issues. This article will explain the changes to the Atlanta classification system and provide pictorial examples of the findings in acute pancreatitis as described by the Atlanta classification system.

Natural history of pancreatitis-induced splenic vein thrombosis: a systematic review and meta-analysis of its incidence and rate of gastrointestinal bleeding

BACKGROUND

Pancreatitis-induced splenic vein thrombosis (PISVT) is an acquired anatomic abnormality that impacts decision making in pancreatic surgery. Despite this influence, its incidence and the rate of associated gastrointestinal (GI) bleeding are imprecisely known.

METHODS

The MEDLINE, EMBASE, Cochrane Central Register of Clinical Trials and Cochrane Database of Systematic Reviews databases were searched from their inception to June 2010 for abstracts documenting PISVT in acute (AP) or chronic pancreatitis (CP). Two reviewers independently graded abstracts for inclusion in this review. Heterogeneity in combining data was assumed prior to pooling. Random-effects meta-analyses were performed to estimate percentages and 95% confidence intervals.

RESULTS

After review of 241 abstracts, 47 studies and 52 case reports were graded as relevant. These represent a cohort of 805 patients with PISVT reported in the literature. A meta-analysis of studies meeting inclusion criteria shows mean incidences of PISVT of 14.1% in all patients, 22.6% in patients with AP and 12.4% in patients with CP. The incidence of associated splenomegaly was only 51.9% in these patients. Varices were identified in 53.0% of patients and were gastric in 77.3% of cases. The overall rate of GI bleeding was 12.3%.

CONCLUSIONS

Although reported incidences of PISVT vary widely across studies, an overall incidence of 14.1% is reported. Splenomegaly is an unreliable sign of PISVT. Although the true natural history of PISVT remains unknown, the collective reported rate of associated GI bleeding is 12.3%.

Diffuse splenic infarction in a case of severe acute pancreatitis

Splenic infarction is rare in inflammatory diseases of the pancreas, although the spleen and its vessels have an intimate relation with the pancreas. Most reported cases are of focal infarction, and treatment is mostly conservative. The authors report a case of diffuse splenic infarction in a 17-year-old boy with severe acute pancreatitis who presented with massive upper gastrointestinal bleeding and was treated with splenectomy.

Imaging of acute pancreatitis: prognostic value of computed tomographic findings

Although most cases of acute pancreatitis are uncomplicated and resolve spontaneously, the presence of complications has significant prognostic importance. Necrosis, hemorrhage, and infection convey up to 25%, 52%, and 80% mortality, respectively. Other complications such as pseudocyst formation, pseudoaneurysm formation, or venous thrombosis increase morbidity and mortality to a lesser degree.We review the computed tomographic findings of complications associated with acute pancreatitis with emphasis on their prognostic significance and impact on clinical management.

Protecting effects of a large dose of dexamethasone on spleen injury of rats with severe acute pancreatitis

BACKGROUND AND AIMS

To explore the protecting effects and mechanisms of dexamethasone on spleen injury in rats with severe acute pancreatitis (SAP).

METHODS

The rats were randomly divided into a model control group, treated group and sham-operated group. The contents of plasma endotoxin, serum NO, phospholipase A(2) enzyme (PLA(2)) and endothelin-1 (ET-1) were determined. The mortality rate, pathological changes and changes of Bax and Bcl-2 protein expression levels and apoptotic indexes in the spleen of rats were observed in all groups, respectively, at 3, 6 and 12 h after operation.

RESULTS

Although the survival rate was significantly higher in the treated group than in the model control group, there was no significantly different between them (P > 0.05). The expression levels of Bax and Bcl-2 proteins and apoptotic indexes were significantly higher in the treated group than in the model control group at different time points (P < 0.05 or P < 0.01) while other blood indexes contents and pathological severity scores of spleen were significantly lower in the treated group than in the model control group (P < 0.05, P < 0.01 or P < 0.001).

CONCLUSION

Dexamethasone can protect spleen from injury during SAP mainly by reducing the content of inflammatory mediators in blood.

Acute pancreatitis: radiologic scores in predicting severity and outcome

Acute pancreatitis (AP) is a common inflammatory disease which can be mild and self-limiting without complications or severe with prolonged hospitalization, high morbidity, and high mortality. Different radiological scoring systems to predict severity and outcome in AP have been developed since the early 1990s. In the meantime, new insights in the pathophysiology of AP and consequently, therapeutic management of these patients have been introduced. The purpose of this review is therefore (1) to describe the current terminology and new concepts in the pathophysiology, (2) to outline the long existing and newly developed radiological scoring systems in prediction of severity and outcome with their respective advantages and limitations, and (3) to define the role of radiological prognostic scoring systems in the new environment of perception of the last decade. Risk stratification in AP requires scoring systems that can be calculated early in the course of disease which allows time for intervention. For that reason, scoring systems based on necrosis are not useful in severity prediction. The recent developed radiological scoring systems based on signs of systemic inflammatory response syndrome and organ dysfunction are promising in prediction of severity early after onset of AP.

Update on acute pancreatitis: ultrasound, computed tomography, and magnetic resonance imaging features

Imaging of patients with acute pancreatitis requires an understanding of the subtypes and complications that were defined at the Atlanta symposium in 1992. In the last decade, several new entities have been recognized with important clinical implications. In this article, the radiological aspects of the terminology and classification of acute pancreatitis are reviewed and new entities are clarified. The roles of ultrasound, computed tomography, and magnetic resonance imaging in the diagnosis and evaluation of acute pancreatitis and its complications are discussed and the limitations of each imaging technique, when interpreting pancreatic and peripancreatic inflammatory disease, are addressed.

Toward an update of the atlanta classification on acute pancreatitis: review of new and abandoned terms

OBJECTIVES

The 1992 Atlanta classification is a clinically based classification system that defines the severity and complications of acute pancreatitis. The purpose of this review was to assess whether the terms abandoned by the Atlanta classification are really discarded in the literature. The second objective was to review what new terms have appeared in the literature since the Atlanta symposium.

METHODS

We followed a Medline search strategy in review and guideline articles after the publication of the Atlanta classification. This search included the abandoned terms: "phlegmon," "infected pseudocyst," "hemorrhagic pancreatitis," and "persistent pancreatitis."

RESULTS

A total of 239 publications were reviewed, including 10 guideline articles and 42 reviews. The abandoned terms "hemorrhagic pancreatitis" and "persistent pancreatitis" are hardly encountered, in contrast, both "infected pseudocyst" and "phlegmon" are frequently used, and several authors question their abandonment. New terminology in acute pancreatitis consists of "organized pancreatic necrosis," "necroma," "extrapancreatic necrosis," and "central gland necrosis."

CONCLUSIONS

This review demonstrates that the Atlanta classification is still not universally accepted. Several abandoned terms are frequently used, and new terms have emerged that describe manifestations in acute pancreatitis that were not specifically addressed during the Atlanta symposium.

The natural history of pancreatitis-induced splenic vein thrombosis

OBJECTIVE

To determine the natural history of pancreatitis-induced splenic vein thrombosis with particular attention to the risk of gastric variceal hemorrhage.

SUMMARY BACKGROUND DATA

Previous studies have suggested that splenic vein thrombosis results in a high likelihood of gastric variceal bleeding and that splenectomy should be performed to prevent hemorrhage. Recent improvements in cross-sectional imaging have led to the identification of splenic vein thrombosis in patients with minimal symptoms. Our clinical experience suggested that gastric variceal bleeding in these patients was uncommon.

METHODS

A computerized index search from 1993 to 2002 for the medical records of patients with a diagnosis of pancreatitis was performed. Fifty-three patients with a diagnosis of pancreatitis and splenic vein thrombosis were identified. The medical records of these patients were reviewed, and follow-up was completed, including the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ).

RESULTS

Gastrosplenic varices were identified in 41 patients (77%) with varices evident on computed tomography (CT) in 40 of 53 patients, on esophagogastroduodenoscopy (EGD) in 11 of 36 patients, and on both CT and EGD in 10 of 36 patients. This risk of variceal bleeding was 5% for patients with CT-identified varices and 18% for EGD-identified varices. Overall, only 2 patients (4%) had gastric variceal bleeding and required splenectomy. Functional quality of life was better than historical controls surgically treated for chronic pancreatitis.

CONCLUSION

Gastric variceal bleeding from pancreatitis-induced splenic vein thrombosis occurs in only 4% of patients; therefore, routine splenectomy is not recommended.
