ARTICLE HIGHLIGHTS
Research background
Due to the lack of specific symptoms and signs of bleeding caused by Meckel’s diverticulum (MD), preoperative diagnosis is difficult, and it is easy to be clinically misdiagnosed or even missed. As double-balloon enteroscopy (DBE) is a highly precise examination method in MD diagnosis, the study aims to analyze the characteristic clinical manifestations of patients with intestinal disease MD complicated with digestive tract hemorrhage; as well as to evaluate the value of DBE in MD diagnosis and the prognosis after laparoscopic diverticula resection.
Research motivation
The study investigated the prevalent population of MD in a retrospective study to guide early screening and preventive treatment for high-risk individuals; explore the causes of bleeding in MD to facilitate early preventive measures, compare the advantages of DBE with other examination methods to assist in the rational formulation of clinical diagnosis and treatment strategies; and evaluating the therapeutic effectiveness of laparoscopic resection of MD and further exploring more optimal treatment approaches.
Research objectives
The study objectives were to analyze the diagnostic value of DBE in patients with MD and bleeding.
Research methods
The study retrospectively analyzed relevant data from 84 MD patients between January 2015 and March 2022 and recorded their clinical manifestations, auxiliary examination, and follow-up after laparoscopic diverticula resection. The clinical data of 84 patients diagnosed with MD and hemorrhage by DBE and other auxiliary examinations (small intestine CT, nuclide scan, and CE) in the past 7 years were retrospectively analyzed. A dual-balloon colonoscopy system (EN-450P5, a diagnostic endoscope, or 450T5, a therapeutic endoscope) was used. Clinical data were collected and analyzed, which included sex, age, bleeding characteristics, blood routine, biochemical indicators, coagulation function test, imaging or endoscopy, postoperative pathological examination, and follow-up results.
Research results
Firstly, MD with bleeding was more common in young men, and was mostly manifested as dark red bloody stool, with less bleeding. Secondly, we combined the endoscopic manifestations with the pathological results of patients with MD complicated by bleeding. It was found that combined ulcer was the main cause of MD bleeding. The formation of ulcer and mucosal layer hyperplasia were related to gastric mucosa/pancreatic tissue, which guided clinicians to be aware of gastric mucosa/pancreatic tissue heterotopic. Thirdly, this study found that DBE and 99mTc-pertechnetate scanning had obvious advantages for the diagnosis of MD complicated with bleeding, and laparoscopic surgical resection for MD complicated with bleeding could obtain a better prognosis, guiding clinicians to make the best choice in diagnosis and treatment.
Research conclusions
This study showed that MD with bleeding was more common in young men, and most patients presented with dark red stool defecation. Following the occurrence of bleeding, the evaluation of the shock index revealed a value significantly less than 1, thus most patients with hemorrhage tolerated DBE examination. DBE was used as the first choice for examination, and laparoscopic diverticulectomy had a good prognosis. The diagnostic and treatment procedures for small intestinal bleeding should be further study to the specific characteristics of the bleeding, anemia, and other relevant parameters.
Research perspectives
The small intestine is currently a blind spot for most examination methods. DBE addresses this gap. At our center, it has been observed that a significant portion of unexplained gastrointestinal bleeding is often associated with small intestine diseases. MD is the most common cause of small intestine bleeding. Clearly defining the diagnostic role of DBE in small intestine diseases is beneficial for formulating rational clinical diagnosis and treatment plans.
