An unpredictable gastrointestinal bleed.

A 65-year-old male complained of persistent melena for 6 days, and displayed anemia symptoms without hematemesis, vomiting, and abdominal distention. He was diagnosed as ruptured aneurysm of aortic sinus Valsalva, and had received coronary artery occlusion 1 month ago. After the operation, he was continually prescribed clopidogrel 75 mg once daily. The laboratory examination showed blood hemoglobin concentration was 60 g/L without other conspicuous abnormality. Unfortunately, neither esophagogastroduodenoscopy (EGD) nor colonoscopy found no obvious bleeding lesions. And abdominal computed tomography angiography (CTA) and enhanced computed tomography (CT) showed no obvious abnormal findings. Moreover, capsule endoscopy revealed small intestinal with mucosal erosion (Figure 1A). After discontinued clopidogrel, blood transfusion, and support therapy, his symptoms was resolved with negative fecal occult blood, continued clopidogrel 75 mg once daily, and uneventfully discharged 1 week later.

[Two Cases of Portal Vein Stent Placement for Portal Vein Stenosis Due to Recurrence of Pancreatic Cancer].

We report 2 cases of portal vein stent placement for malignant portal stenosis due to recurrence of pancreatic cancer with symptoms of portal hypertension. Case 1: The patient was a 68-year-old female. Five years ago, a mass was found around the aorta on a computerized tomography(CT)scan taken after a residual pancreatectomy for pancreatic cancer. It was diagnosed as lymph node recurrence and S-1 therapy was started. As further tumor enlargement led to portal vein compression, venostasis around the ascending jejunum, anemia, and black stools, a portal vein stent was placed. The portal vein blood flow was improved, the collateral vessels disappeared, and the patient no longer experienced anemia or black stool. Case 2: A 75-year-old female patient underwent a subtotal gastric-sparing pancreaticoduodenectomy and combined resection of the portal vein for pancreas head cancer. On a postoperative CT scan taken 6 months later, a mass compressing the portal vein appeared, which was diagnosed as a local recurrence. As thrombocytopenia was observed, a portal vein stent was placed before starting chemotherapy. The portal vein blood flow and the platelet count improved. Portal vein stenting is an effective procedure for malignant portal stenosis, improving portal blood flow and clinical symptoms.

Characteristics of Immune Checkpoint Inhibitor-Associated Gastritis: Report from a Major Tertiary Care Center.

BACKGROUND: Immune checkpoint inhibitors (ICIs) have increased our ability to treat an ever-expanding number of cancers. We describe a case series of 25 patients who were diagnosed with gastritis following ICI therapy. MATERIALS AND METHODS: This was a retrospective study involving 1712 patients treated for malignancy with immunotherapy at Cleveland Clinic from January 2011 to June 2019 (IRB 18-1225). We searched electronic medical records using ICD-10 codes for gastritis diagnosis confirmed on endoscopy and histology within 3 months of ICI therapy. Patients with upper gastrointestinal tract malignancy or documented Helicobacter pylori-associated gastritis were excluded. RESULTS: Twenty-five patients were found to meet the criteria for diagnosis of gastritis. Of these 25 patients, most common malignancies were non-small cell lung cancer (52%) and melanoma (24%). Median number of infusions preceding symptoms was 4 (1-30) and time to symptom onset 2 (0.5-12) weeks after last infusion. Symptoms experienced were nausea (80%), vomiting (52%), abdominal pain (72%), and melena (44%). Common endoscopic findings were erythema (88%), edema (52%), and friability (48%). The most common diagnosis of pathology was chronic active gastritis in 24% of patients. Ninety-six percent received acid suppression treatment and 36% of patients also received steroids with an initial median dose of prednisone 75 (20-80) mg. Within 2 months, 64% had documented complete resolution of symptoms and 52% were able to resume immunotherapy. CONCLUSION: Patients presenting with nausea, vomiting, abdominal pain, or melena following immunotherapy should be assessed for gastritis and if other causes are excluded, may require treatment as consideration for complication of immunotherapy.

Clinical Predictors of a Positive Ct Angiogram Study Used for the Evaluation of Acute Gastrointestinal Hemorrhage.

BACKGROUND: Acute gastrointestinal (GI) bleeding is one of the leading causes of emergency department visits and hospital admissions. CT angiography (CTA) has had an expanding role in the evaluation of acute GI bleeding because it is rapidly performed, widely available, reasonably sensitive and provides precise localization when positive. We attempted to identify patient and clinical characteristics that predict CTA results in order to help guide the utilization of this modality in patients with acute GI bleeding. METHODS: In this retrospective study, we analyzed all CTAs performed for the evaluation of GI bleeding in the Duke University healthcare system between October 2019 and March 2020. We captured patient characteristics including age, sex, vital signs, hemoglobin, platelets, PT/INR, and anticoagulation status. Study indications were grouped by suspected source of bleeding: upper GI bleeding (hematemesis or coffee-ground emesis) vs small bowel bleeding (melena or "dark stools") vs lower GI bleeding (hematochezia or bright red blood per rectum (BRBPR)). Chi-square, Wilcoxon, t test, and multivariate logistic regression were used to describe and assess the relationship between patient characteristics and study outcomes (Table 1).

Forty-three patients (13.6%) had a CTA positive for active bleeding. Multivariable logistic regression showed that after controlling for age, mean arterial pressure (MAP) and indication, only a hemoglobin drop from baseline was significantly associated with a positive CTA. For each 1 g / dL drop in hemoglobin from the patient's baseline, the odds of a positive CT increased by 1.17 (OR 1.17 95% CI 1.00 - 1.36, p = 0.04). Age (OR 1.02 95% CI 0.99 - 1.04, p = 0.06) and hematochezia / BRBPR (OR 2.09 95% CI 0.94-4.64, p = 0.07) approached statistical significance. CONCLUSIONS: In patients who present to the hospital with GI bleeding, CTA can be a helpful triage tool that is most helpful in older patients with suspected lower GI bleeding with a drop in hemoglobin from baseline. Other clinical factors including MAP and the use of anticoagulants were not predictive of a positive CTA.

Pure testicular choriocarcinoma with gastrointestinal metastasis and paraneoplastic symptoms: a case report.

BACKGROUND: Pure testicular choriocarcinoma is a rare type of non-seminomatous germ cell tumor extremely poor prognostic with the tendency to bleed at the metastatic site. At the time of the diagnosis, 70% of patients have metastatic lesions. Depending on the site of the metastasis, symptoms vary. Gastrointestinal involvement is seen in less than 5% of cases, mostly in the duodenum. CASE PRESENTATION: We present a 47 years old male with testicular choriocarcinoma involving the jejunum, lung, liver, and kidney presenting with acute abdominal pain, melena, and dyspnea with some paraneoplastic symptoms. The patient had increased, severe and constant pain in the right lower quadrant for the previous four days. Additionally, he was complaining of nausea, vomiting, anorexia, and a history of melena for the last 10 days. Dyspnea on exertion, hemoptysis, and dry cough were the symptoms he was suffering from, for almost one year. The patient's general appearance was pale, ill, and thin with 10 kg of weight loss during the last some months. The computed tomography (CT) scan reported multiple metastatic lesions in both liver lobes and the left kidney. Pathologic study of the samples of small bowel lesions showed metastatic choriocarcinoma. Following the patient had been referred to an oncologist to start the chemotherapy regime. Finally, the patient has expired after 40 days of his first admission. CONCLUSIONS: Testicular choriocarcinoma is a rare but fatal malignancy among young men. Gastrointestinal metastases are infrequent involvement represented by melena and acute abdominal pain, obstruction, and mass. Physicians should consider it as a differential diagnosis for acute abdomen and gastrointestinal bleeding causation.

Prospective observational study on clinical and epidemiological profile of adult patients presenting to the emergency department with suspected upper gastrointestinal bleed.

BACKGROUND AND OBJECTIVE: Bleeding from the upper gastrointestinal (GI) tract is one of the common medical emergencies. In this study, we assessed patients' socio-demographic and clinical characteristics and the association of clinical characteristics with treatment outcomes among patients with suspected upper gastrointestinal bleed (UGIB) presenting to the emergency department (ED). At present, there is a scarcity of data on UGIB in Northern part of India. MATERIAL AND METHOD: The study was a single-center, prospective observational study conducted at an urban tertiary care center. Consecutive patients with suspected UGIB were enrolled in the study from August 2020 to February 2022. A detailed history was obtained, including demographic data such as age and sex, presenting complaints, history of presenting illness, history related to co-morbidities, addiction, and drug history. Pre-endoscopic Rockall and Glasgow-Blatchford Score were calculated for each patient. The patients were subsequently followed up till discharge from the hospital. The final outcomes with regard to mortality, need for blood transfusion, length of emergency department stay, and discharge were noted. RESULT: 141 patients were included in the study. The mean age of the patients with suspected UGIB was 48 ± 14 years. 115 (81.6%) patients were male. The most common co-morbidity was chronic liver disease (40;28.4%). The most frequent presenting complaint in this study was hematemesis (96; 68.1%), followed by melena (76;53.9%). The mean (Standard Deviation, SD) of the Rockall Score was 2.46 ± 1.75. The mean (SD) of the Glasgow Blatchford Score was 12.46 ± 3.15 in patients with UGIB. CONCLUSION: In our study, hematemesis was the most prevalent symptom of suspected UGIB, followed by melena. Portal hypertension was the most common cause of UGIB. Most frequent comorbidities in patients suspected of UGIB were alcohol intake, Nonsteriodal Antiinflammatory Drugs (NSAIDs) abuse, and co-morbidities such as underlying chronic liver disease, hypertension, and diabetes. Early endoscopy can be of great utility to reduce morbidity and mortality.

A full hemostatic repertoire in a complex cirrhotic patient.

A 55-year-old woman with cirrhosis was admitted for acute decompensation caused by portal vein thrombosis. Ten days later, the patient presented melena. Esophagogastroscopy revealed two gastric polyps, both with bleeding stigmata. One of the polyps was removed with a diathermic loop, after adrenalin injection, while in the other the "ligate and let go" technique was applied, after biopsy. A "metallic tulip-bundle" technique, combining through the scope and over-the-scope clips, was applied for hemostasis. This case underlines how the combination of various endoscopic techniques may be useful to manage upper gastrointestinal bleeding, especially in patients with important comorbidities.

A Study of Upper GI Endoscopic Findings in Patients Presented with Upper GI Bleed.

INTRODUCTION: Bleeding from upper gastrointestinal tract is approximately five times more common than bleeding from lower gastrointestinal tract. The most common cause has been gastroduodenal ulcer disease, Esophageal varices, Mallory-Weiss tear. MATERIALS: It is an observational study carried out in General medicine department in GSL hospital in patients presented with history of vomiting of frank blood and/or passed dark coloured stools were chosen for this study with an aim to find out the prevalence of nature of lesion on Upper Gastro Endoscopy in patients admitted for UGI bleed and to find out the prevalence of nature of lesion. RESULT: Detailed history regarding the UGI bleeding like number of times of hematemesis approximate quantity of blood vomited each time, associated with malena. Symptoms of common diseases that can lead to UGI bleeding and detailed history of drug intake like aspirin, other NSAIDs, steroids and symptoms due to blood loss were recorded in the questionnaire. CONCLUSION: The peptic ulcer disease was the most common lesion found on endoscopy with prevalence of 54% and Varices with prevalence of 16% Minor UGI bleed was the commonest presentation. Majority of lesions (60%) presented with minor UGI bleed 28% lesions presented as moderate UGI bleed. Only 8% presented as major UGI bleed. Varices account for the most common cause for major UGI bleed contributing 50%. Gastric ulcer was commonest lesions accounting for 37 cases (37%) among 72 cases having single acid peptic lesions on endoscopy. The second most common is common is duodenal ulcer (31%).

[Successful portal vein stent placement for chronic portal vein stenosis 5 years after pancreatoduodenectomy:a case report].

A 73-year-old man underwent pancreatoduodenectomy 5 years previously, and portal vein stenosis was observed immediately after surgery. A collateral vein with varices around the hepaticojejunostomy gradually developed. The patient experienced repeated episodes of melena that required transfusion. Enteroscopy confirmed varices around the hepaticojejunostomy, caused by portal vein stenosis, which was the source of intestinal bleeding. Varices were treated by placing an expandable metallic stent in the stenotic portal vein through a percutaneous transhepatic route. Although the portal vein stenosis was severe, the guidewire was successfully maneuvered into the superior mesenteric vein and stent placement was successful. Subsequently, the collateral vein disappeared and no further melena was observed.

Upper gastrointestinal bleeding in coronavirus disease 2019 patients.

PURPOSE OF REVIEW: Upper gastrointestinal bleeding (UGIB) has significant morbidity and UGIB cases have been described in coronavirus disease 2019 (COVID-19) patients. Management of this condition can be challenging considering both the possible severe COVID-19-related pneumonia as well as the risk of the virus spreading from patients to health operators. The aim of this paper is to review the most recent studies available in the literature in order to evaluate the actual incidence of UGIB, its clinical and endoscopic manifestations and its optimal management. RECENT FINDINGS: UGIB has an incidence between 0.5% and 1.9% among COVID-19 patients, and it typically presents with melena or hematemesis. Peptic ulcers are the most common endoscopic findings. High Charlson Comorbidity Index (CCI), dialysis, acute kidney injury and advanced oncological disease increase the risk for UGIB. Although anticoagulants are commonly used in COVID-19 patients they are not associated with an increased incidence of UGIB. Conservative management is a common approach that results in similar outcomes compared to upper GI endoscopic treatment. Apparently, UGIB in COVID-19 seems not have a detrimental effect and only one study showed an increased mortality in those who developed UGIB during hospitalization. SUMMARY: Incidence of UGIB in COVID-19 patients is similar to that of the general population. Despite the widespread use of anticoagulants in these patients, they are not associated with an increased risk of UGIB. Conservative management could be an effective option, especially for patients that are at risk of intubation.

Modified N score is helpful for identifying patients who need endoscopic intervention among those with black stools without hematemesis.

OBJECTIVES: Although black stools are one of the signs of upper gastrointestinal bleeding, not all patients without hematemesis need endoscopic intervention. There is no apparent indicator to select who needs treatment thus far. The aim of this study was to establish a novel score that predicts the need for endoscopic intervention in patients with black stools without hematemesis. METHODS: We retrospectively enrolled 721 consecutive patients with black stools without hematemesis who underwent emergency endoscopy from two facilities. In the development stage (from January 2016 to December 2018), risk factors that predict the need for endoscopic intervention were determined from the data of 422 patients by multivariate logistic regression analysis, and a novel scoring system, named the modified Nagoya University score (modified N score), was developed. In the validation stage (from January 2019 to September 2020), we evaluated the diagnostic value of the modified N score for 299 patients. RESULTS: Multivariate logistic regression analysis revealed four predictive factors for endoscopic intervention: syncope, the blood urea nitrogen (BUN) level, and the BUN/creatinine ratio as positive indicators and anticoagulant drug use as a negative indicator. In the validation stage, the area under the curve of the modified N score was 0.731, and the modified N score showed a sensitivity of 82.0% and a specificity of 58.8%. CONCLUSIONS: Our modified N score, which consists of only four factors, can identify patients who need endoscopic intervention among those with black stools without hematemesis.

XI factor deficiency as cause of recurrent gastrointestinal bleeding.

We present the case of a 73-year-old woman with no relevant medical history. She was admitted for a 3-month intermittent melena. The physical exam was unremarkable. Blood tests revealed anemia (hemoglobin 7.4 g/dL), raised urea (69 mg/dL), normal platelets and coagulation. Gastroscopy was performed with active oozing bleeding in the fundus and gastric body. Endoscopic fulguration of the potential lesions with holmium laser was performed. She was discharged with resolution of the symptoms and analytical improvement. However, the patient required hospitalization two weeks later due to recurrence of melena and anemia.

A "window" in the duodenal bulb: an atypical presentation of chronic cholecystitis.

A 74-year-old male presented with melena and fatigue, without fever or abdominal pain. Laboratory examination revealed anemia, leukocytosis, elevated C-reactive protein levels and conjugated hyperbilirubinemia with elevated liver enzymes. Upper endoscopy identified blood in the stomach and duodenum and a 6 mm hole in the anterosuperior surface of the duodenal bulb with spontaneous drainage of a bloody brownish content. The mucosa surrounding the hole was normal and there was a discrete mucosal flap that throbbed with air insufflation. Abdominal computed tomography identified a fistulous tract between the duodenal bulb and the gallbladder with a 2 mm caliber, suggesting a cholecystoduodenal fistula. Diagnosis is often difficult because symptoms are nonspecific and variable but gastrointestinal bleeding is a rare clinical presentation.

Clinical Presentation of Cases with Upper Gastro - Intestinal Bleeding.

Acute upper gastrointestinal bleeding (UGIB) is a common emergency and can be a serious condition that requires hospitalization, rapid evaluation and management. The usual presentation is hematemesis (vomiting of blood or coffee ground-like material) and/or melena (black, tarry stools) 1. UGIB occurs more commonly in men and older subjects. PUD is the most common cause of UGIB in the US accounting for about 50% of the cases, whereas in tropical country like India, esophageal varices attribute to half the cases. Esophago-Gastro-Duodenoscopy [EGD] is a primary diagnostic and therapeutic modality in the setting of UGIB. MATERIAL: Prospective study. Forty patients who have presented with frank blood or coffee ground color vomitus and/or melena were considered for this study. All patients greater than 18 years of age were included. Their clinical presentation, hemogram and endoscopic findings were analyzed. Descriptive statistical analysis has been applied. OBSERVATION: In our study, the age distribution was between 23 and 87 years. There is a male preponderance with 65 % males and 35%females. Among 40 patients,42.5%had varices, 17.5% had Peptic Ulcer Disease and12.5% had Erosive Gastritis. The other causes of UGIB include Pangastritis(10%), Mallory Weiss Tear(7.5%), Polyp(5%), Esophagitis(2.5%), Coagulopathy induced bleed(2.5%) and Carcinoma stomach(2.5%). Of the 40 cases admitted, only 3 patients (7.5%) had massive Upper GI Bleed.10 patients (25%) had moderate bleed and 27 patients (67.5%) had mild bleed. Amongst the patients with massive bleed, an important cause is esophageal varices(66.7%). A total of 21 (52.5%) patients have recovered. There was one death(2.5%) amongst the cases which was not attributed to UGIB. 14 patients(45%) has residual disease of which 42.5% were of variceal bleed. Patients with variceal bleed have undergone banding and have been asked to regularly follow up for check endoscopy and banding till their eradication. There was 1 patient of residual disease with Carcinoma stomach(2.5%) who has been initiated on chemotherapy. CONCLUSION: Hematemesis is much commoner than melena in the presentation of upper GI bleed. EGD has a diagnostic as well as therapeutic role in UGIB .In this study endoscopy provided diagnosis in 97.5% of patients. In this cross sectional study, the most common cause of upper GI bleed was esophageal varices, with alcoholic cirrhosis being the main cause of portal hypertension. Varices remain to be the most common cause of UGIB in both males and females, however, the percentage is more in males as compared to females. Varices are an important cause of massive variceal bleed.

A Rare Case of Upper Gastrointestinal Bleeding: Osler-Weber-Rendu Syndrome.

Osler-Weber-Rendu disease, also known as hereditary hemorrhagic telangiectasia (HHT), is a rare, autosomal dominant condition that affects approximately 1 in 5000 patients causing abnormal blood vessel formation. HHT patients have mucocutaneous telangiectasias and arteriovenous malformations in various organs. The most prominent symptom of HHT is epistaxis, which, together with gastrointestinal bleeding, may cause iron deficiency anemia. This study is a case report of a 62-year-old patient who was admitted to the Department of Gastroenterology due to acute upper gastrointestinal bleeding and a history of recurrent epistaxis and melena for 4 days, which was confirmed in digital rectal examination. Urgent upper gastrointestinal endoscopy revealed active bleeding from multiple angioectatic spots with bright-looking salmon-colored patches in the antrum and the body suggestive of HHT. The bleeding from two angioectatic spots was stopped by argon plasma coagulation, and four clips were placed to provide good hemostasis. The patient was treated with a proton pomp inhibitor infusion and iron infusion. She was discharged with no signs of GI bleeding, normalized iron levels and a diagnosis of HHT. She was referred to further genetic testing, including evaluation of first-degree relatives. She also had performed unenhanced thin-cut computed tomography (CT) with angiography to exclude the presence of pulmonary arteriovenous malformations (PAVMs). Due to the fact that the patient did not manifest any other HHT-related symptoms and that the instrumental screening discloses no silent AVMs in other organs, the "watch-and-wait strategy" was applied. Although, Osler-Weber-Rendu syndrome is widely described in the medical literature, effective treatment of gastrointestinal telangiectasias is not always available and still lacks standardization to date, which makes the management of gastroenterological involvement still a challenging issue.

[A Case of Jejunal Cancer Treated by Laparoscopic Partial Jejunectomy].

The patient was a 30s male visited our hospital with the complaints of abdominal pain and melena. The internal medicine physician could not detect the cause of the melena by upper and lower gastrointestinal endoscopy. Although the patient resolved with a fast as conservative management so he left our hospital once, he relapsed nausea and abdominal pain. He visited our department. We performed surgery under a preoperative diagnosis of intestinal obstruction. The histopathological diagnosis was moderate differentiated jejunal adenocarcinoma(Stage ⅡA). At present, 1 year 7 months since surgery, the patient survives although with lymphnode recurrence.

[A Case of Rectal Cancer with Hemorrhagic Shock with Bleeding Controlled via Stent Placement That Underwent Radical Resection after Preoperative CRT].

Colorectal stents are used mainly for the palliative treatment of colorectal obstruction or preoperative re-obstruction. However, the hemostatic effect of covered stents reportedly induced bleeding of esophageal cancer and varicosities. Here, we report a case of mildly obstructed rectal cancer with severe anemia and hemorrhagic shock that resulted in pulsatile tumor bleeding. Curative surgical resection was performed successfully after the administration of chemoradiotherapy. The patient was a 67-year-old man. A nearby doctor diagnosed him with anemia(Hb 4.6 g/dL)and referred him to our hospital, where he was diagnosed with rectal cancer at the Ra position. He was immediately hospitalized owing to voluminous melena, loss of consciousness, and hematoma formation on the posterior aspect of the head. Urgent CF was performed due to persistent melena and decreased blood pressure. The pulsatile bleeding from rectal cancer was identified. To address the diffuse bleeding, a covered stent was placed to induce hemostasis and dilation. This also served as a bridge to surgery( BTS). Hemostasis was successfully achieved. After chemoradiotherapy( CRT), a laparoscopic low anterior resection was performed. Radical surgery was performed, and S-1 was taken 6 months postoperatively. At 2 years postoperatively, metastatic recurrence was not observed.

A POEMS syndrome patient with idiopathic non-cirrhotic portal hypertension received the transjugular intrahepatic portosystemic shunt: a case report and literature review.

Polyneuropathy, organomegaly, endocrinopathy, M-protein, skin changes (POEMS) syndrome is a rare plasma cell dyscrasia disease involving multiple organs combined with idiopathic non-cirrhotic portal hypertension. It has been reported only four times in the English literature. Here, we present the first case of a 62-year-old male POEMS syndrome patient with portal hypertension treated with the transjugular intrahepatic portosystemic shunt (TIPS), after he presented with a 10-day history of melena. The diagnosis of POEMS syndrome was given because the patient presented with polyneuropathy, monoclonal plasma cell proliferative disorder, sclerotic bone lesions, splenomegaly, lymphadenopathy, ascites, hypothyroidism, and hyperpigmentation. The presence of portal hypertension was confirmed by esophageal varices, congested and edematous stomach body, splenomegaly, and transudate ascites in which the serum-ascites albumin gradient of ascites fluid was over 11 g/L (a concentration considered to be associated with POEMS syndrome), as no other causes were found. The patient fasted and received conservative drug treatments on admission, but symptoms of melena soon recurred within 1 week after resuming his diet. After TIPS and venous embolization were performed, symptoms of bleeding were effectively controlled, while the patient subsequently developed hepatic encephalopathy, which ultimately led to death. The presence of gastrointestinal bleeding in POEMS syndrome with idiopathic non-cirrhotic portal hypertension indicates a poor prognosis. Given that this was the first patient to receive TIPS, and although the incidence of hepatic encephalopathy has increased, TIPS is still acceptable for refractory variceal bleeding.

Parallel disease activity of Behçet's disease with renal and entero involvements: a case report.

BACKGROUND: Behçet's disease (BD) is a systemic inflammatory vasculitis with both autoimmune and autoinflammatory properties. Renal involvement in BD and its spontaneous remission have been rare. We herein describe a case of parallel disease activity of BD with entero and renal involvements, followed by a spontaneous remission without corticosteroid treatment. CASE PRESENTATION: A 54-year-old woman who had a 4-year history of BD, maintained with colchicine treatment, suffered abdominal pain, hemorrhagic stool and diarrhea. Physical examination revealed strong tenderness in the entire abdomen. Laboratory test results showed increased levels of inflammation, and a computed tomography scan revealed edematous intestinal wall thickening with ascites. Blood and stool cultures showed no specific findings. Since she was suspected to have developed panperitonitis with acute enterocolitis, she started treatment with an antibacterial agent under bowel rest. Her abdominal symptoms gradually improved, while diarrhea and high levels of inflammatory reaction persisted. Colonoscopy revealed discontinuous abnormal mucosal vascular patterns and ulcerations in the whole colon except for the rectum, and histological analyses of the intestine demonstrated transmural mucosal infiltration of inflammatory cells without epithelioid granuloma or amyloid deposition. Based on these findings, she was diagnosed with entero BD. Meanwhile, pedal edema appeared during her hospitalization. Urinalysis results were consistent with nephrotic syndrome, thus a renal biopsy was performed. Light microscopy showed no obvious glomerular and interstitial abnormalities, whereas electron microscopy revealed foot process effacement without immune complex deposition or fibrillary structure, compatible with minimal change disease (MCD). Only with conservative therapy, her proteinuria decreased, followed by a complete remission in 3 weeks from the onset of edema. The coincident episode of MCD was finally diagnosed as renal BD that paralleled disease activity to entero BD. She started adalimumab administration, resulting in the further improvement of diarrhea and inflammatory levels. CONCLUSIONS: This is the first report to demonstrate MCD as renal involvement of BD along with the disease activity of entero BD.

Hemobilia due to Hepatic artery pseudoaneurysm secondary to collateral circulation formation after liver trauma: a case report.

BACKGROUND: Hemobilia due to rupture of hepatic artery pseudoaneurysm and recurrent hemorrhage caused by hepatic artery collateral circulation are both rare complications after liver trauma. There have been a number of separate reports of both complications, but no cases have been reported in which the two events occurred in the same patient. Here we report a recurrent hemorrhage in the bile duct due to hepatic artery pseudoaneurysm secondary to collateral circulation formation after hepatic artery ligation in a patient with liver trauma. CASE PRESENTATION: A 52-year-old male patient was admitted to our hospital for liver trauma (Grade IV according to the American Association for the Surgery of Trauma (AAST) grading system) with active bleeding after a traffic accident. Hepatic artery ligation was performed for hemostasis. Three months after the surgery, the patient was readmitted for melena and subsequent hematemesis. Selective angiography examination revealed the formation of collateral circulation between the superior mesenteric artery and right hepatic artery. Moreover, a ruptured hepatic artery pseudoaneurysm was observed and transcatheter arterial embolization (TAE) was performed for hemostasis at the same time. After the treatment, the patient recovered very well and had an uneventful prognosis until the last follow-up. CONCLUSION: For patients with hepatic trauma, the selection of the site of hepatic artery ligation and the diagnosis and treatment methods of postoperative biliary hemorrhage are crucial for the prognosis of the disease.
