Received: May 2022; Accepted: June 2022; Published online: 27 July 2022 Abstract: Jejunal Dieulafoy’s lesion is difficult to diagnose due to its rarity, intermittent hemorrhage, and lesion site, which is largely inaccessible to conventional endoscopes. A 39-year-old man, who had no underlying disease, pre- sented to the emergency department (ED) with weakness, dizziness, and dry cough with a history of several rec- tal bleeding episodes in the last few years. Endoscopy was normal, and the colon was full of clots on colonoscopy, and no gross pathology was found. On computed tomography (CT) angiography, a hyperdensity was seen in the middle of the jejunum, possibly suggesting contrast extravasation. Due to decreased hemoglobin of the patient, and hemodynamic instability, the patient became a candidate for surgery. A palpable lesion in the Jejunum was touched that opened longitudinally, which revealed active arterial bleeding from the nipple-like lesion. This seg- ment was resected, and an anastomosis was performed. Histopathological examination of the small intestine confirmed a Dieulafoy’s lesion. It seems that, when upper endoscopy and colonoscopy fail to identify the cause of gastrointestinal bleeding, a Dieulafoy’s lesion should be included in the differential diagnoses.

Gallard in 1884 (1). In 1898, the French surgeon Paul Georges Dieulafoy gave a more detailed description of this clinical condition, calling it an "exulceratio simplex"(2). In 1944, Levine and Valk were the first to describe a jejunal aneurysm with a submucosal artery rupture (3). The jejunum is where 1% of all confirmed cases of DL are identified (4). Jejunal DL is difficult to diagnose due to its rarity, intermittent hemorrhage, and lesion site, which ∗Corresponding Author: Tooraj Zandbaf; Faculty of Medicine, Bazarche Sarab, Imam Khomeini 14, Mashhad, Iran. tooraj.zandbaf@gmail.com, https://orcid.org/0000-0002-4882-5058, Tel:+98-9155114523; +98-513- 2250041, Fax Number: +98-513-2250048, ORCID: https://orcid.org/0000- 0003-2840-056X. is largely inaccessible to conventional endoscopes (5). With a male-to-female ratio of 1.2:1, Jejunal DL has a lit- tle male predominance, with ages ranging from 10 to 95 years (55 ± 24 years; median, 82 years). The majority of individuals were diagnosed between the ages of 70 and 80. Most instances were found in developed countries. Several patients were on anticoagulants and/or nonsteroidal anti- inflammatory drugs due to their older age and underlying chronic medical issues (6). DL is a rare and uncommon cause of massive gastrointesti- nal (GI) bleeding, and therefore, we would like to present our clinical experience with this unusual case to get more famil- iar with its various facets.

Case presentation The patient was a 39-year-old man who presented to the emergency department (ED) with rectal bleeding, weakness, dizziness, and dry cough. The patient had a history of several rectal bleeding episodes in the last few years, as well as oral opium consumption. No history of underlying diseases was reported. An upper endoscopy had been performed a year ago, in which no lesions were seen. The patient was referred to our center from another hospital, where he had received 4 packed cells due to rectal bleeding. An initial evaluation in the ED revealed a normal temperature of 37.3°C, blood pressure of 90/60 mmHg, heart rate of 110 beats per minute, respiratory rate of 28 breaths per minute, and normal oxygen saturation of 96% in room air. Lung ex- amination was not remarkable. On abdominal examination, there was a slight generalized tenderness. The blood test re- sults of the patient are presented in Table 1. We think the cause of the patient’s thrombocytopenia was previous trans- fusion of packed cells. Sputum polymerase chain reaction (PCR) for SARS-CoV-2 infection was positive. The patient was admitted in COVID-19 ward and was resuscitated using intravenous crystalloids and four units of packed cells after a central venous (CV ) line was inserted. A chest x-ray was taken from the patient, which indicated homogeneous opac- ity in the lower zone of both lungs (Figure 1A). The internist visited the patient and asked for a consultation with a gen- eral surgeon due to the lack of severe pulmonary problems as well as the significant rectal bleeding. Consultation was per- formed with a general surgeon, and computed tomography (CT) angiography and gastroenterologist consultation were requested. Endoscopy was normal and on colonoscopy, the colon was full of clots, which made it impossible to examine the colon closely. At this time, CT angiography was performed. Hyper- density was seen in the middle of the jejunum loops, possi- bly suggesting contrast extravasation. A small volume of free fluid was seen in the abdominal and pelvic cavities (Figure 1B). At this time, the patient began to decompensate, and the patient’s hemoglobin decreased, resulting in need for addi- tional packed cells and surgery. After laparotomy and during abdominal exploration, a palpable lesion in the small intes- tine was touched in 90 cm of ligament Treitz. At the site of the lesion, the small intestine opened longitudinally, which revealed active arterial bleeding from the nipple-like lesion. This segment of the small intestine was resected, and an anastomosis was performed. No other pathology was found in the abdomen. The patient was transferred to the intensive care unit (ICU). The patient’s gastrointestinal bleeding was stopped, and hemodynamics stabilized. After establishing bowel habits, the liquid diet was started, and finally, the patient was dis- Table 1: The laboratory findings of the patient Blood Test Result Normal Range White Blood Cells (x103 /µl) 17.3 4-10 Hemoglobin (g/dl) 5.3 13.3-17.2 Hematocrit (%) 16 38.9-50.9 Platelets (x103 /µl) 58 150-450 ESR1(mm/h) 3 <20 CRP2 (mg/L) 16.8 Up to 5.0 Blood Sugar(mg/dl) 112 75-100 Sodium(mEq/L) 130 136-146 Potassium(mEq/L) 6.3 3.5-5.5 D-Dimer (ng/FEU ml) 946 <500 Blood Urea Nitrogen(mg/dl) 59 10-50 Creatinine(mg/dl) 1.5 0.7-1.4 Alanine Aminotransferase (IU/L) 73 Up to 41 Aspartate Aminotransferase (IU/L) 88 Up to 37 Amylase (IU/L) 443 0.00-86.00 Prothrombin Time (Seconds) 17.3 10.5-14 Partial Thromboplastin Time (Seconds) 28 10-40 INR3 1.6 - 1: Erythrocyte Sedimentation Rate. 2: C-Reactive Protein. 3.

Discussion Jejunal DL is an unusual cause of gastrointestinal bleeding, which can be severe and fatal. DL is a vascular anomaly with a diameter of 1 to 3 mm, which is 10 times bigger than the size of a healthy submucosal artery (7). A tiny mucosal de- fect with no surrounding mucosal inflammation character- izes this condition. These abnormal arteries usually take a tortuous path and protrude (2-5 mm) through the mucosal defect, making them prone to slight mechanical damage (8). Antiplatelet drugs and alcohol intake were found to be risk factors for DL formation in the upper gastrointestinal tract. The mean hemoglobin level in patients with jejunal DL was found to be 8.4 g/dL at the time of presentation. The quantity of blood units given out varied from two to nine. The pos- sible presenting symptoms of dizziness/fatigue (11%) and iron-deficiency anemia can be explained by the decline in hemoglobin levels (10%) (6). Jejunal DL remains difficult to diagnose. The intermittency of the bleeding and lack of access to the jejunum with a regu- lar endoscope makes it difficult to detect using conventional endoscopy. Endoscopic guidance in the narrow jejunal canal can also be challenging (9). In our patient, we faced diag- nostic challenge and a variety of differential diagnoses were considered when endoscopy and colonoscopy failed to iden- tify the source of gastrointestinal bleeding.

The diagnosis can be further complicated by the presence of ambiguous clinical symptoms that could be mistaken for peptic ulcer disease or gastrointestinal malignancies. As a re- sult, the efficiency of traditional endoscopy in Jejunal DL is debatable (6). In our patient, after conventional endoscopies failed to detect the origin of bleeding, small bowel tumor was the most likely differential diagnosis we assumed. Mesenteric angiography can be useful in cases of unidenti- fied cause of bleeding when hemodynamic instability is evi- dent. The use of computed tomography angiography to de- tect extra-gastric culprit vessels is very important. CT angiog- raphy is a quick and simple method that can identify bleed- ing rates as low as 0.5 mL/minute (10). The most sensitive tool for diagnosing active GI bleeding is radionuclide stud- ies, which may detect bleeding rates as low as 0.1 mL/minute (11). Capsule endoscopy and push enteroscopy have also been tried, with mixed results, particularly in stable patients who had unremarkable initial endoscopies. Single and double balloon enteroscopy are the best procedures with diagnos- tic yields of 96% and 98%, respectively. Since they comple- ment noninvasive procedures like capsule endoscopy, these device-assisted enteroscopies are more effective in identi- fying DL. They provide secure and efficient diagnostic and therapeutic access to the jejunum via deep direct endoscopic access. The clinical presentation and capsule endoscopy re- sults are important in determining oral or anal approach (6,12). Endoscopic therapy was initially used to treat 64% of patients. In 32% of cases, direct surgical therapy was used, while angiographic embolization was performed in 4% of cases. In most hemodynamically unstable individuals, sur- gical assessment is required. Intraoperative enteroscopy can be used to help locate the bleeder during surgery (6). Yehya et al. presented a 19-year-old guy with multiple episodes of hematemesis and hematochezia. After resusci- tation, a CT angiography was performed, which revealed no areas of active extravasation. The results of emergency up- per and lower endoscopy were unclear. A tagged red blood cell scan revealed active bleeding in the proximal jejunum. The patient began to decompensate, necessitating additional blood products and vasopressors. Immediate operative in- tervention was accomplished and the bleeding Dieulafoy’s lesion in the jejunum was discovered. Intestinal resection and primary anastomosis were performed (11). Saada et al. presented a 27-year-old man with acute ab- domen, bloody diarrhea, and syncope. Upper and lower en- doscopies, as well as angiography, failed to reveal a bleeding location during the investigation. Following that, a scintig- raphy revealed increased radiotracer activity in the right ab- domen, which was consistent with small intestinal bleeding. Based on these findings, the patient underwent an emer- gency laparotomy, which revealed the bleeding location in the jejunum and allowed for surgical resection (13). Unlike these two cases, our patient was in his fourth decade of life and his CT angiography showed contrast extravasation in the jejunum. Similarly, our patient’s gastrointestinal bleeding was surgically controlled. An obscure gastrointestinal bleeding occurs when the cause of bleeding cannot be identified using upper endoscopy or colonoscopy, and a DL, among other conditions, should al- ways be included in the differential diagnosis. Before any surgical intervention, if the patient’s condition is stable and there is enough time, CT angiography or radionuclide scan probably help identify the source of the bleeding and assist the surgeon during the operation.

Kalantari et al. 4 4. Conclusion When upper endoscopy and colonoscopy fail to identify the cause of gastrointestinal bleeding, a DL should be included in the differential diagnosis. Surgery for a DL is now uncom- mon due to significant developments in endoscopic meth- ods. If endoscopy fails to locate the source of bleeding, fur- ther imaging can be performed. In urgent circumstances, where additional imaging is not possible owing to a lack of time or resources, appropriate excision of the lesion for com- plete remission of the disease process should be undertaken. 5.
