Appendiceal Bleeding, A Rare Yet Important Cause of Lower Gastrointestinal Bleed.

Lower gastrointestinal bleeding accounts for 20 to 25% of all gastrointestinal bleedings. Appendiceal bleeding is a rare, yet important cause of lower gastrointestinal bleed; in many cases, it can be misdiagnosed as obscure gastrointestinal bleeding. Here, we present a case of appendiceal bleeding in an elderly female. A 79-year-old female presented with acute onset of gastrointestinal bleeding of same-day duration. Investigations showed that she had an appendiceal bleed originating from an ulcer secondary to a small appendicolith, which has passed through the appendiceal orifice, combined with her aspirin use. Within 12 hours, a laparoscopic appendectomy was performed. No evidence of malignancy or vascular malformation was detected, and the post-operative course was smooth, with resultant discharge at day 3 after her surgery. For lower gastrointestinal bleeding, it is crucial for the endoscopist to reach the terminal ileum during the colonoscopy, and thoroughly inspect the orifice of the appendix to assess any source of bleed including but not limited to Dieulafoy's lesion, angiodysplasia or any vascular malformation. An effective treatment option for appendiceal bleeding is surgical management with appendectomy. Alternative approaches such as vessel embolization and endoscopic treatment have been reported to successfully control bleeding; nevertheless, the risk of acute appendicitis and recurrent bleeding following these procedures can be challenging to manage, potentially leading the patient to still need a surgical treatment with an appendectomy. Appendiceal bleeding is a rare, yet important cause of lower gastrointestinal bleed; in many cases, it can be misdiagnosed as obscure gastrointestinal bleeding.

Clinical features, treatments and prognosis of appendiceal bleeding: a case series study

BackgroundAppendiceal bleeding is a rare cause of lower gastrointestinal bleeding, could be overlooked and diagnosed as obscure gastrointestinal bleeding. Due to limited real-world cases, the optimized management of appendiceal bleeding is unclear. We here shared our experiences in the past 20 years.MethodsA retrospective study was conducted at West China Hospital of Sichuan University. We reviewed data of 28,175 colonoscopies from 43,095 gastrointestinal bleeding patients between June 2003 and June 2023. Six patients diagnosed as appendiceal bleeding were included. Data including symptoms, laboratory tests, imaging results, endoscopic findings, treatment and prognosis were collected and analyzed.ResultsAppendiceal bleeding accounts for 0.014% in gastrointestinal bleeding patients. Of the six patients, five were male, with a mean age of 48.5 years. Hematochezia was the most common symptom. The etiology included appendiceal angiodysplasia, appendicitis and appendectomy associated bleeding. Hemostasis was achieved by appendectomy, endoscopic therapy or medication according to different cases. One patient did not receive any treatment because of self-limiting bleeding.ConclusionsThe diagnosis of appendiceal bleeding is challenging, repeated flushing during endoscopy is helpful. Appendectomy is the priority option for treatment as well as the etiology clarification, therapeutic endoscopy and medication could be considered case by case.

WITHDRAWN: Appendiceal bleeding caused by vascular malformation: A case report and literature review

Introduction and importanceAcute lower gastrointestinal bleeding (LGIB) is common in clinical practice, however, appendiceal bleeding is extremely rare, which easy to be missed and misdiagnosed. Case presentationWe presented a case of a 33-year-old female who complained of hematochezia that had lasted for 1 day, colonoscopy showed continuous bleeding in the appendiceal orifice. A laparoscopic appendectomy was performed immediately, a pulsating blood vessel can be seen in the mesangium of the appendix, accordingly, active bleeding into the appendicular lumen was considered. Appendiceal pathology showed a large number of hyperplastic vessels were seen in the appendix mucosa and capillary vessels were dilated. Clinical conclusionAppendiceal bleeding is rare, lack of related guidelines and consensus, the preoperative detection of appendiceal bleeding is often challenging. Colonoscopy is extremely important, bowel preparation is not recommended for patients with acute LGIB routinely or only low-dose bowel preparation is recommended. Laparoscopic appendectomy is the most appropriate treatment for appendiceal bleeding. DiscussionIn our case, we provided the relevant data of computed tomography (CT), colonoscopy, pathology and laparoscopic surgery, and analysed the appendiceal bleeding caused by vascular malformation, to provide clinical experience.

Appendiceal bleeding in an elderly male: a case report and a review of the literature

BackgroundThe prevalence of acute lower gastrointestinal bleeding has been increased including colonic diverticulitis and angioplasty. However, appendiceal bleeding is extremely rare.Case presentationWe present a case of lower gastrointestinal bleeding from the appendix in an elderly male who presented with melena. Appendiceal bleeding was diagnosed using lower gastrointestinal endoscopy, and laparoscopic appendectomy was performed. The patient did not have melena postoperatively, and was discharged 6 days after the surgery.ConclusionIt is important to distinguish appendiceal bleeding from lower gastrointestinal bleeding and to treat it as soon as possible with less invasiveness.

An unexpected cause of lower gastrointestinal bleeding.

Although appendiceal bleeding is rare, physicians should keep this finding in mind as a possible cause of bleeding from the right colon because the colonoscopic diagnosis may be essential in determining the need for surgical intervention.

Successful Endoscopic Clipping of Appendiceal Orifice Bleeding: A Technical Maneuver to Convert an Emergency to an Elective Procedure

Objective: We report a rare case of an elderly man with appendiceal bleeding successfully treated with endoscopic placement of hemoclips. Methods: We describe the patient’s clinical presentation, laboratory test results, imaging, and treatment. Results: An 89-year-old man presented with two episodes of bloody diarrhea that occurred two hours apart. Colonoscopy revealed active bleeding from the appen- diceal orifice. Hemostasis was achieved with epinephrine injections followed by placement of five hemoclips to effectively close the appendiceal orifice. An abdominal computed tomography (CT) showed an irregular thick- ening of the appendix wall, raising the possibility of an appendiceal mass. On hospital day 4, the patient underwent appendectomy and partial cecectomy. Pathology revealed focal ulceration of the mucosa without malig- nancy. The remainder of the patient’s hospital course was uneventful.Conclusion: The endoscopic methods used in our case proved effective in achieving hemostasis and allowed the patient to be stabilized prior to surgery. It is unclear whether longer monitoring would reveal any possible long-term complications after endoscopic closure of the appendix. It would be of interest to further investigate this approach to assess the long-term safety and efficacy of this procedure.

Massive Lower Gastrointestinal Bleeding from the Appendix

Massive rectal bleeding from the appendix, considered a rare case of lower gastrointestinal bleeding, is not easily recognized by various diagnostic modalities. A multidisciplinary approach for both a diagnosis and a differential diagnosis is important because the identification of the bleeding site is crucial to proceed to a proper intervention and there are various causes of appendiceal bleeding. Because early colonoscopy plays an important role in the diagnosis and management of lower gastrointestinal hemorrhage, we report a case of a life threatening massive rectal bleeding from the appendix diagnosed by colonoscopy. We also present a review of the literature.

A Case of Successful Colonoscopic Treatment of Acute Appendiceal Bleeding by Endoclips

Lower gastrointestinal bleeding is a common disease among elderly patients. The common sources of lower gastrointestinal bleeding include vascular disease, Crohn's disease, neoplasm, inflammatory bowel disease, hemorrhoid, and ischemic colitis. However, bleeding from the appendix has been reported very rarely in patients with lower gastrointestinal tract bleeding. In general, after a colonoscopic diagnosis of appendiceal bleeding, a laparoscopic or surgical appendectomy would be recommended. We report a case of successful colonoscopic treatment of appendiceal bleeding without complications by endoclips. This report suggests that colonoscopic clipping is a safe and effective means to treat bleeding from appendiceal lesions. Further study is needed to evaluate procedure-related complications and to confirm the procedure's safety and efficacy.

Colonoscopic Clipping as a Treatment for Appendiceal Bleeding

Bleeding from the appendix has been reported very rarely in patients with lower-gastrointestinal-tract bleeding. In general, after a colonoscopic diagnosis of appendiceal bleeding, laparoscopic or surgical appendectomy would be recommended. Two patients with continuous bleeding from the appendix were treated with partial occlusion of the appendiceal orifice by colonoscopic clipping. In neither case was there evidence of further active bleeding over the following 12 months. This is the first report of such a treatment in the English literature.

Acute Lower Gastrointestinal Bleeding Due to Appendiceal Mucosal Erosion

Acute lower gastrointestinal hemorrhage associated with the appendix is rare. We report on a 42-year-old male patient who presented with hematochezia from solitary appendiceal bleeding. The patient was admitted to our hospital with rectal bleeding, and abdominal computed tomography identified active contrast leakage in the distal portion of the appendix. During a subsequent urgent colonoscopy, active bleeding in the appendiceal orifice was identified. The patient was successfully treated with a laparoscopic appendectomy and hematochezia did not recur postoperatively. Microscopic examination revealed an eroded appendiceal mucosa, focal inflammatory infiltrates, and a normal submucosal vessel without evidence of vascular malformation.

Acute Lower Gastrointestinal Bleeding from the Appendix Diagnosed by Abdominal Multidetector Computed Tomography: A Case Report and Review of the Literature

Appendiceal bleeding is a kind of lower gastrointestinal bleeding. For treatment, it is essential to identify the location of the lower gastrointestinal tract bleeding. Appendiceal bleeding has some diagnostic difficultie. It is a very rare condition, and colonoscopy shows only the appendiceal orfice. Recently, multidetector computed tomography has increasingly been used in the diagnostic evaluation of most vascular diseases. Herein, we report the case of an appendiceal bleeding diagnosed by using abdominal multidetector computed tomography, and we present a the literature.

HEMORRHAGIC FOCAL GASTRODUODENAL LESIONS

At the present time a large number of histories are being reviewed of patients who came to the Mayo Clinic complaining of gastro-intestinal hemorrhage. In this study only benign gastroduodenal lesions are included. In most of the series of cases that came to operation ulcers, gastric, duodenal or gastrojejunal, were found. There was, however, a surprisingly large number of cases in which a definite ulceration was not demonstrable at the operating table. In some of these, there were gastric, duodenal or esophageal varices; in a few, there was evidence of marked hepatitis; in others, splenomegaly or cirrhosis of the liver, and in a certain number it was assumed that a blood dyscrasia was responsible for the hemorrhages. Again, in other instances, some pathologic conditions of the or appendix were found, and it was assumed that the condition was probably one commonly termed gallbladder bleeding or appendiceal bleeding. In some
