Successful laparoscopic treatment of hemorrhage from the appendix with phlegmonous acute appendicitis: a case report and review of the literature

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

BACKGROUND

Appendiceal 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.

METHODS

A 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.

RESULTS

Appendiceal 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.

CONCLUSIONS

The 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.

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

BACKGROUND

The prevalence of acute lower gastrointestinal bleeding has been increased including colonic diverticulitis and angioplasty. However, appendiceal bleeding is extremely rare.

CASE PRESENTATION

We 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.

CONCLUSION

It is important to distinguish appendiceal bleeding from lower gastrointestinal bleeding and to treat it as soon as possible with less invasiveness.

A therapeutic barium enema is a practical option to control bleeding from the appendix

BACKGROUND

Acute lower gastrointestinal hemorrhage originating from the appendix is rare and often intractable, because it is almost impossible to approach the bleeding point by endoscopy. We herein describe the first case of bleeding from the appendix, which was successively controlled by a therapeutic barium enema administered into the appendix.

CASE PRESENTATION

A 71-year-old male visited our hospital because of melena. He has been receiving an anti-coagulation drug, ticlopidine hydrochloride, for 10 years. By an emergency colonoscopy, a hemorrhage was detected in the appendix, and the lesion responsible for the bleeding was regarded to exist in the appendix. Two hundred milliliters of 50 W/V% barium was sprayed into the orifice of the appendix using a spraying tube. The bleeding could thus be immediately stopped, and a radiological examination revealed the accumulation of barium at the cecum and the orifice of the appendix. The barium accumulation disappeared by the next day, and no obvious anal bleeding was observed. Two weeks after stopping the bleeding from the appendix, an appendectomy was performed to prevent any further refractory hemorrhaging. The patient has had no complaints of any abdominal symptoms or anal bleeding for 10 months.

CONCLUSIONS

A therapeutic barium enema is a useful procedure to control bleeding from the appendix and to avoid emergency surgery, such as partial cecectomy and hemicolectomy.

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.

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.

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.
