BACKGROUND/OBJECTIVE
Cribriform-morular thyroid carcinoma (CMTC) was considered a variant of papillary thyroid carcinoma (PTC) but is a separate entity in the 2022 World Health Organization classification. CMTC has an association with familial adenomatous polyposis (FAP). Our objective is to report a case of CMTC who was subsequently diagnosed with FAP, to highlight these associated entities and implications for management.
CASE REPORT
A 15-year-old female with a history of iron-deficiency anemia and alpha-gal syndrome presented with several years of goiter and dysphagia. She also noted unintentional weight loss, abdominal pain, melena and hematochezia, and symptomatic anemia. Physical examination was significant for multiple thyroid nodules. Laboratory results revealed normal thyroid function and iron deficiency. Multiple nodules were visualized on thyroid ultrasound, and fine needle aspiration biopsy was consistent with PTC. Total thyroidectomy was performed with a revised diagnosis of multifocal CMTC, with administration of adjuvant radioactive iodine due to persistent disease. Genetic testing confirmed FAP and she was referred for upper endoscopy, colonoscopy, and an evaluation for colectomy.
DISCUSSION
There are no best practice guidelines for management of CMTC. Management of CMTC is guided by FAP status; sporadic cases can be managed with hemithyroidectomy, while FAP-associated cases are better managed with total thyroidectomy. Recurrence is usually managed with surgical resection. The decision to treat with adjuvant radioactive iodine is often extrapolated from management of classic PTC.
CONCLUSION
Thyroid carcinoma in the setting of extensive family history of colorectal carcinoma should arouse suspicion for CMTC. Patients with CMTC should receive a referral for colonoscopy and genetic testing for FAP.

INTRODUCTION
Dieulafoy's lesion (DL) is a vascular malformation that can lead to massive gastrointestinal bleeding. It's usually found in the stomach. However, DL's occurrence in atypical sites such as the small bowel and colon is exceptionally rare, posing significant management challenges.
CASE PRESENTATION
In this report, we present two cases of DL occurring in uncommon sites, each managed with distinct approaches. Case 1 is a 50-year-old man admitted to the emergency department due to massive GI bleeding and hemodynamic instability. The diagnosis of DL was established through computed tomography angiography and confirmed by histopathological examination after emergency surgery. Case 2 involves a 68-year-old woman presented with melena due to a colonic DL. This case was successfully managed through an endoscopic hemostasis approach.
DISCUSSION
Dieulafoy's lesions (DL) were first identified as a large submucosal artery lacking typical gastric ulcer characteristics in three of Paul Georges Dieulafoy's patients. This lesion is responsible for approximately 1-2 % of all cases of gastrointestinal bleeding. Endoscopy is the preferred method for diagnosing and managing DL lesions, especially in cases of active bleeding that is accessible. However, if endoscopic treatment or angiographic embolization fails, a surgical approach may be needed.
CONCLUSION
DL presents a diagnostic challenge due to its rarity and is not usually included in the differential diagnosis of gastrointestinal bleeding, particularly when occurring in unusual sites. Endoscopy is the preferred method to identify DL and a possible therapeutic approach in active bleeding. However, if endoscopy hemostasis fails, angiographic embolization or surgical intervention may be required.

Undergoing another surgery after a previous abdominal procedure can sometimes result in significant abdominal adhesions. We present a case of robot-assisted low anterior resection in a patient with rectal cancer who had a urinary reservoir. A 65-year-old male patient underwent robot-assisted total bladder resection and creation of a urinary reservoir for bladder cancer in 2013. He presented with melena. Thus, the findings revealed advanced low rectal cancer. The robot-assisted low anterior resection was performed in 2022. Extensive adhesions were observed in the pelvic space. The indocyanine green function was appropriately used, and the robotic surgery was completed without injury to the urinary reservoir or major complications. The surgical time was 510 min, and the blood loss volume was 15 mL. The patient had been recurrence free for 12 months following the surgery. Robot-assisted surgery can be beneficial for patients with rectal cancer with significant pelvic adhesions.

Gastrointestinal mesenchymal tumors (GIST) are the most prevalent sarcoma tumors affecting the digestive tract. GIST originates from Cajal cells located within the digestive tract's wall. These cells play a crucial role in regulating digestive peristaltism as they are considered pacemaker cells. These tumors are especially located in the stomach (60%) but can also be seen in the small bowel (30%), in which jejunal stromal tumors are estimated to reach (40%). In this case report, we describe a jejunal GIST, which was initially discovered due to active bleeding, serving as the primary symptom, along with an underlying small loop intussusception. In our knowledge, GIST causing an intussusception is a rare entity in literature as well as GIST causing active bleeding. For that aim, we present a 36-year-old male patient, presented to our department with melena. An abdominal computed tomography scan was performed, revealing a small bowel intussusception associated with a 2 cm tumor. Despite the imprecise cause of the bleeding, due to the ongoing active hemorrhage, we decided to proceed with an emergency laparotomy, suspecting a tumorous origin of the bleeding. During the surgery, the tumor was located in the jejunum. The affected jejunal segment containing the tumor was resected, and an anastomosis was performed. Pathology examination confirmed a stromal tumor. The postoperative follow-up was uneventful.

The case is a 78-year-old male. The chief complaint was melena and weight loss. After careful examination, the patient was diagnosed with advanced rectal cancer, and 3 courses of capecitabine plus oxaliplatin therapy were performed as preoperative chemotherapy. He underwent robot-assisted laparoscopic rectal resection, D3 lymphadenectomy, lateral lymphadenectomy, and temporary colostomy, and was discharged on hospital day 15. Postoperative pathological diagnosis showed only ulcerative lesions in the rectum, and malignant cells could not be confirmed. After postoperative adjuvant chemotherapy, the patient is alive without recurrence on an outpatient basis. There are many reports that it is slightly lower than radiotherapy. Therefore, it is important to select a more appropriate preoperative treatment, and the concentration of future cases is recognized.

BACKGROUND
An ectopic bile duct opening into the stomach is a rare congenital anomaly of the biliary system, and thus, there are few case reports with gastric ulcer hemorrhage. Herein, we presented a case of ectopic bile duct concomitant with gastric ulcer hemorrhage.
CASE PRESENTATION
A 75-year-old woman was referred to our hospital because she repeatedly vomited blood and had melena. Endoscopic hemostasis was attempted for hemorrhage from a gastric ulcer located on the anterior wall of the antrum. However, the bleeding was difficult to stop, and a laparoscopic distal gastrectomy was performed. Her postoperative course was uneventful. Pathological examination revealed that the bleeding point was an ectopic bile duct. In retrospect, an annual endoscopy performed at her family clinic had revealed a bulge in the same portion of the stomach. Exposure to bile acids from an ectopic bile duct opening can cause gastric mucosal damage and ulceration.
CONCLUSIONS
Ectopic bile ducts opening into the stomach can cause gastric ulcer and hemorrhage. Hemorrhage from a submucosal ridge with ulcer in the stomach may be rarely related to the presence of ectopic bile ducts.

BACKGROUND
Fecal occult blood tests (FOBT) are inappropriately used in patients with melena, hematochezia, coffee ground emesis, iron deficiency anemia, and diarrhea. The use of FOBT for reasons other than screening for colorectal cancer is considered low-value and unnecessary.
METHODS
Quality Improvement Project that utilized education, Best Practice Advisory (BPA) and modification of order sets in the electronic health record (EHR). The interventions were done in a sequential order based on the Plan-Do-Study-Act (PDSA) method. An annotated run chart was used to analyze the collected data.
RESULTS
Education and Best Practice Advisory within the EHR led to significant reduction in the use of FOBT in the ED. The interventions eventually led to a consensus and removal of FOBT from the order set of the EHR for patients in the ED and hospital units.
CONCLUSIONS
The use of electronic BPA, education and modification of order sets in the EHR can be effective at de-implementing unnecessary tests and procedures like FOBT in the ED and hospital units.

OBJECTIVES
To determine the risk difference of arterial and venous thromboembolic events between patients with upper gastrointestinal bleeding (UGIB) who received and did not receive tranexamic acid.
DESIGN
Retrospective cohort study.
SETTING
The TriNetX Analytics (Cambridge, MA) Research Network, a deidentified mixed electronic health record and claims-derived database with over 110 million patients, primarily located in the United States.
PATIENTS
A total of 2,016,763 patients diagnosed with hematemesis or melena between October 31, 2003, and October 31, 2023.
INTERVENTIONS
Receipt of tranexamic acid within 7 days of a UGIB diagnosis.
MEASUREMENTS AND MAIN RESULTS
We measured the incidence of thromboembolic events, both venous (deep venous thrombosis [DVT] and pulmonary embolism [PE]) and arterial (cerebrovascular accident [CVA] and myocardial infarction [MI]), within either 7 days of tranexamic acid (for recipients) or 7 days of UGIB diagnosis (for nonrecipients). Subsequently, we developed similar subcohorts using propensity score matching (PSM) for demographic and comorbidity data and reexamined the incidence of thromboembolic events, both before and after excluding any patients with any prior episodes of the outcomes. In all analyses, tranexamic acid recipients experienced significantly more adverse thromboembolic outcomes, with the post-PSM cohorts' risk difference generating an odds ratio of 1.4 for MI (95% CI, 1.2-1.7), 1.6 in CVA (95% CI, 1.3-1.9), 1.8 in PE (95% CI, 1.5-2.3), and 2.1 in DVT (95% CI, 1.8-2.5); all values of less than 0.001.
CONCLUSIONS
Leveraging data from a large, multi-institutional database, we identified a correlation between tranexamic acid use in patients with UGIB and the occurrence of both venous and arterial thromboembolic events. Although the former is well-attested in the literature, the latter finding is more novel, underscoring the need for further prospective research to better characterize the risk-benefit profile of tranexamic acid in the management of gastrointestinal bleeding.

INTRODUCTION
Solid organ malignancies rarely metastasize to the duodenal papilla. We describe a case of primary lung cancer with duodenal papillary metastasis in a patient who presented with melena. To the best of our knowledge, this is only the second report of duodenal papillary metastasis from lung cancer.
CASE PRESENTATION
A 65-year-old woman presented with complaints of anorexia, weight loss, and black stool. Imaging studies led to a clinical diagnosis of stage IVB lung cancer, and anticoagulants were initiated to treat pulmonary artery thrombosis. However, endoscopic hemostasis was challenging because of bleeding from a duodenal papillary tumor. Fortunately, the patient was positive for the plasma epidermal growth factor receptor (EGFR) gene mutation, and osimertinib, an EGFR tyrosine kinase inhibitor, was administered, successfully achieving hemostasis. Subsequently, endoscopic ultrasonography-guided transbronchial needle aspiration of an enlarged mediastinal lymph node and duodenal papillary tumor biopsy confirmed duodenal papillary metastasis of the primary lung adenocarcinoma.
CONCLUSION
Although duodenal papillary metastasis is extremely rare, a good clinical outcome was achieved in this case by considering duodenal papillary metastasis from lung cancer as the differential diagnosis and administering systemic osimertinib therapy.
