Diagnostic challenge between Crohn's disease and intestinal tuberculosis in chronic diarrhea with ulcerated jejunal stenosis: a case report / Desafío diagnóstico entre la enfermedad de Crohn y la tuberculosis intestinal en la diarrea crónica con estenosis yeyunal ulcerada: reporte de un caso

ABSTRACT Intestinal tuberculosis and Crohn's disease are a diagnostic challenge because of the clinical, radiological and endoscopic similarity. The histological and microbiological findings are positive in less than 50%, which delays the correct treatment, putting the patient at risk. We reported a 34-year-old immunocompetent patient with 4 years of malabsorptive diarrhea, weight loss, nocturnal diaphoresis, abdominal pain and an ulcer with stenosis in the jejunum was found; she received empirical anti- tuberculosis treatment with clinical improvement. Later the culture was positive for M. tuberculosis.

RESUMEN La tuberculosis intestinal y la enfermedad de Crohn son un desafío diagnóstico debido a la similitud clínica, radiológica y endoscópica. Los hallazgos histológicos y microbiológicos son positivos en menos del 50%, lo que retrasa el correcto tratamiento, poniendo en riesgo al paciente. Reportamos un paciente de 34 años inmunocompetente con 4 años de diarrea malabsortiva, pérdida de peso, diaforesis nocturna, dolor abdominal y se encontró una úlcera con estenosis en yeyuno; recibió tratamiento empírico antituberculoso con mejoría clínica. Posteriormente el cultivo fue positivo para M. tuberculosis.

Single-balloon Enteroscopy for Diagnosis of Meckel Diverticulum in Adults / 胃肠病学

Background: Meckel diverticulum is one of the most common congenital malformations of the gastrointestinal tract. It is relatively rare in adults and is difficult to make a preoperative diagnosis. Aims: To analyze the clinical characteristics of Meckel diverticulum in adults and to investigate the diagnostic value of single-balloon enteroscopy for adult Meckel diverticulum. Methods: A retrospective study was performed in patients diagnosed as adult Meckel diverticulum by single-balloon enteroscopy at Renji Hospital, School of Medicine, Shanghai Jiao Tong University from Apr. 2011 to Jan. 2019. Results: A total of 30 adult Meckel diverticulum patients were enrolled. Of them, 26 were male and 4 were female with a mean age of (36.1±14.6) years. The mean duration of symptoms ranged from 6 days to 30 years. The prevalence of gastrointestinal bleeding, abdominal pain/diarrhea, and anemia was 73.3% (22/30), 40.0% (12/30), and 50.0% (15/30), respectively. All the diverticula were detected by retrograde single-balloon enteroscopy. The mean distance of diverticulum from the ileocecal valve was (98.7±29.5) cm, and the size of diverticulum opening was 3.25 cm on average. Ulcer was found in 11 cases. Sixteen cases underwent surgical resection, and 12.5% and 18.8% of them were proved to contain ectopic gastric mucosa and ectopic pancreas, respectively. The diagnostic yield of capsule endoscopy and imaging modalities were relatively low (39.1% and 20.7%, respectively). Conclusions: Single-balloon enteroscopy has a high diagnostic value for Meckel diverticulum in adults and may provide guidance for clinical treatment. For adults suspected of Meckel diverticulum, retrograde single-balloon enteroscopy is recommended.

Rapunzel Syndrome Removed with Enteroscopy in a Child / 대한소화기학회지

A trichobezoar is a type of bezoar that is composed of hair. In most cases, it is confined to the stomach, but in rare cases, it may extend to the small intestine. This condition is referred to as Rapunzel syndrome. The therapeutic method for bezoar removal depends on its type, location, and size. Generally, the treatment for Rapunzel syndrome involves surgical laparotomy. Endoscopic removal has also been effective in some cases. On the other hand, complications, such as respiratory difficulty and esophageal impaction may be encountered during endoscopic removal. Until now, the successful endoscopic removal of trichobezoars has been limited to the stomach or duodenum. This paper reports the case of a 4-year-old female patient with Rapunzel syndrome whose trichobezoar reached the proximal jejunum. The trichobezoar was removed without complications using an electrosurgical knife and snare through a single-balloon enteroscopy. The trichobezoar can be removed successfully using enteroscopy under general anesthesia without abdominal laparotomy in young children. Therefore, this method of removal can be considered preferentially for children with Rapunzel syndrome.

Comparative study of different intestinal loop labeling methods under the aid of single balloon enteroscopy for ERCP / 中国内镜杂志

Objective To compare the effect of different intestinal loop labeling methods under single balloon enteroscopy for ERCP. Method From June 2015 to May 2017, 36 cases of single balloon enteroscopy assisted ERCP patients, according to the study period divided into A, B, C three groups, In group A, the afferent loops were confirmed by titanium clips, labeled intestinal loops, and the B group was identified by methylene blue labeling and intestinal loops, and the C group was the control group, the operation time of the 3 groups was recorded (the starting time of operation, the time of reaching the nipple of the input loop or the time of the Roux-en-Y biliary anastomosis), the incidence of complications and the success rate of operation. Results The operation time was 42.17 min in group A and 59.83 min in group C, and there was significant difference between the two groups (P < 0.01),There was no statistically significant difference between group A and group B, group B and group C (P > 0.05), the complication rate and the operation success rate were not statistically different between the three groups (P > 0.05). Conclusion The operation time of the input loop at the time of ERCP assisted by single balloon enteroscopy has a clear advantage over the examination of the intestinal loop with a titanium clip.

Comparison of the Efficacy and Safety of Single- versus Double-Balloon Enteroscopy Performed by Endoscopist Experts in Single-Balloon Enteroscopy: A Single-Center Experience and Meta-Analysis

BACKGROUND/AIMS: Studies concerning the efficacy and safety of single-balloon enteroscopy (SBE) compared with that of double-balloon enteroscopy (DBE) often appear to be conflicting. However, previous studies were performed by endoscopists who were less experienced in SBE compared with DBE. METHODS: We performed a retrospective analysis of SBE and DBE data performed by a single enteroscopist, with expertise in SBE, using a prospective balloon-assisted enteroscopy registry from 2013 to 2015. Furthermore, we performed a comprehensive literature search and meta-analysis of available studies, including the current study, to clarify the efficacy and safety of SBE versus DBE. RESULTS: A total of 65 procedures in 44 patients with SBE and 74 procedures in 69 patients with DBE were analyzed. There were no significant differences in diagnostic yield (61.1% vs 77.3%, respectively, p=0.397), therapeutic yield (39.1% vs 31.8%, respectively, p=0.548), and complication rate (4.4% vs 2.3%, p=1.000). In the meta-analysis, which included four randomized controlled trials and three observational studies, there were no significant differences in the pooled relative risk and odds ratio for diagnostic and therapeutic yield and complications of SBE compared with those of DBE. CONCLUSIONS: The performance of SBE appears to be similar to that of DBE in terms of diagnostic and therapeutic yield and complications.

Training in Endoscopy: Enteroscopy

The balloon-assisted enteroscope has been regarded as the standard device for direct visualization of deep small bowels and allows for the diagnosis and treatment of small bowel disease. At the beginning, its application was focused on the diagnosis of obscure gastrointestinal bleeding, inflammatory bowel disease, and small bowel tumor. However, the indications are being expanded to various therapeutic procedures, not only confined to bleeding control. With the expansion of the indications, the need to perform enteroscopy effectively and safely is increasing. Recent studies have been focused on the diagnostic yield, therapeutic yield, and long-term outcomes of the device. However, with the increasing number of procedures, procedural guidelines and quality indicators are also needed.

A Case of Primary Small Bowel Melanoma Diagnosed by Single-Balloon Enteroscopy

Although metastasis from cutaneous malignant melanoma to the small intestine is not uncommon, primary small bowel melanoma (SBM) is extremely rare. This case report describes a rare case of primary SBM, diagnosed by single-balloon enteroscopy. A 74-year-old man presented with recurrent melena. Upper endoscopy and colonoscopy were unremarkable. Abdominal computed tomography (CT) revealed an ileal mass with ileo-ileal intussusception. Subsequent single-balloon enteroscopy identified an ileal tumor, which was histologically diagnosed as melanoma. Extensive clinical examination did not reveal any primary cutaneous lesions. To the best of our knowledge, this is the first case of primary SBM in South Korea.

Diagnostic and Therapeutic Value of Single-balloon Enteroscopy in Suspected Small Intestinal Diseases / 胃肠病学

Background:Single-balloon enteroscopy(SBE)is a new method for the examination of small intestine,its clinical value in suspected small intestinal diseases need to be further studied. Aims:To evaluate the diagnostic and therapeutic value of SBE in suspected small intestinal diseases. Methods:A total of 73 suspected small intestinal diseases patients who had undergone 81 SBE examinations from July 2011 to October 2013 at Chengdu Military General Hospital were retrospectively examined,indications,diagnostic and therapeutic value of SBE in suspected small intestinal diseases were analyzed. Results:Of all the 81 examinations,33(40. 7% )were obscure gastrointestinal bleeding,29(35. 8% ) incomplete intestinal obstruction,and 19(23. 5% )chronic abdominal pain or diarrhea. The intubation depth was 230 cm for the oral approach,and 100 cm for the anal approach. The diagnostic yield of SBE was 67. 9% ,the main lesions were small intestinal ulcer,small intestinal inflammation,small intestinal tumor,small intestinal polyp. A total of 8 patients underwent endoscopic therapy,of whom 5 underwent endoscopic hemostatic therapy and 3 underwent resection of polyp. No serious complications were found. Conclusions:SBE is a safe and reliable diagnostic and therapeutic method for suspected small intestinal diseases,and its main indications are obscure gastrointestinal bleeding and incomplete intestinal obstruction.

Single Balloon Enteroscopy-Assisted Endoscopic Retrograde Cholangiopancreatography in Patients Who Underwent a Gastrectomy with Roux-en-Y Anastomosis: Six Cases from a Single Center

Patients with altered anatomy such as a Roux-en-Y anastomosis often present with various pancreaticobiliary problems requiring therapeutic intervention. However, a conventional endoscopic approach to the papilla is very difficult owing to the long afferent limb and acute angle of a Roux-en-Y anastomosis. Balloon-assisted enteroscopy can be used for endoscopic retrograde cholangiopancreatography (ERCP) in patients with altered anatomy. We experienced six cases of Roux-en-Y anastomosis with biliary problems, and attempted ERCP using single balloon enteroscopy (SBE). SBE insertion followed by replacement with a conventional endoscope was attempted in five of six patients. The papilla was successfully approached using SBE in all cases. However, therapeutic intervention was completed in only three cases because of poor maneuverability caused by postoperative adhesion. We conclude that in patients with Roux-en-Y anastomosis, the ampulla can be readily accessed with SBE, but longer dedicated accessories are necessary to improve this therapeutic intervention.

Deep Enteroscopy: Which Technique Will Survive?

The advent of deep enteroscopy (DE) has dramatically changed diagnostic and therapeutic approaches to small bowel diseases. Unlike capsule endoscopy, which is unable to obtain biopsies or treat a disease, DE techniques have diagnostic and therapeutic capabilities. Double-balloon enteroscopy (DBE) was introduced in 2001, and single-balloon enteroscopy (SBE) and spiral enteroscopy (SE) were subsequently developed for small bowel investigation. In published reports comparing these different enteroscopy techniques, most comparative parameters (depth of insertion, complications, learning curve, diagnostic yield, and therapeutic yield) were comparable among DBE, SBE, and SE. However, the procedure duration appears to be shorter for SE than for DBE and SBE. The rate of complete enteroscopy is clearly superior for DBE, compared with SE and SBE. Because these results do not indicate an increase in diagnostic or therapeutic yield, the clinical impact of complete enteroscopy remains controversial. According to previous studies, the three DE methods seem to be equally effective and safe in the clinical setting. Although larger randomized controlled trials are needed to evaluate the procedural characteristics and clinical impact, the selection of an enteroscopic technique should be based on availability and the endoscopist's experience.

Single-balloon enteroscopy assisted ERCP for diagnosis and treatment of patients with biliary obstruction after gastrointestinal reconstruction / 中华消化内镜杂志

Objective To evaluate the feasibility and safety of performing endoscopic retrograde cholangiopancreatography (ERCP) assisted by single-balloon enteroscopy (SBE) in patients with biliary obstruction after gastrointestinal reconstruction.Methods Clinical data about 7 cases of single-balloon enteroscopy assisted-ERCP (SBE-ERCP) were summarized including the completion of treatment,operation time,and complications for retrospective study.Results The papilla or anastomotic site was reached and therapeutic ERCP were performed successfully in 6 patients.The overall success rate was 85.7％ (6/7),and the mean operation time of SBE-ERCP was 42 min (ranging from 28 to 72 min).The afferent loop and papilla were failed to be confirmed in 1 patient.No complication such as perforation,pancreatitis or bleeding ocurred in all the 7 patients.Conclusion Single-balloon enteroscopy assisted-ERCP (SBE-ERCP) is feasible and relatively safe in postsurgical patients with gastrointestinal reconstruction.

Learning curve, diagnostic yield and safety of single balloon enteroscopy.

Background: Single balloon enteroscopy (SBE) is a recently developed diagnostic modality to assess small bowel mucosa. The data on learning curve of SBE is scanty. We aimed to assess the learning curve, diagnostic yield and safety of SBE Methods: All patients who underwent SBE at our centre from December 2007 to December 2010 were included retrospectively. The clinical details, enteroscopy findings and procedure related details were obtained for each patient from a prospectively maintained database. The extent of small bowel visualised with increasing number of procedures by a single endoscopist (Endoscopist A) who performed most of the procedures was used to estimate the learning curve using locally weighted regression curve. The diagnostic yield and complications rates of SBE were also estimated. The study was approved by the institute review board and ethics committee. Results: Ninety SBEs were performed in 84 patients (age: 42+15 years, 27.4% females). 57 procedures were performed (32 antegrade and 25 retrograde) by endoscopist A. There was gradual improvement in the extent of small bowel visualised during the first 15 procedures via antegrade route followed by flattening of curve. The retrograde route showed no definite trend towards improvement during the procedures performed. The overall diagnostic yield of SBE was 32.1%. There was no complication except for mild self-limiting abdominal pain in one patient. Conclusions: SBE via antegrade route has a higher success rate and better learning curve than the retrograde route. SBE is a safe procedure and helps in establishing a diagnosis in one-third of the patients examined.

Two Cases of Ileal Dieulafoy Lesion with Massive Hematochezia Treated by Single Balloon Enteroscopy

Ileal Dieulafoy lesion is an unusual vascular abnormality that can cause gastrointestinal bleeding. It can be associated with massive, life-threatening hemorrhage and requires urgent angiographic intervention or surgery. Ileal Dieulafoy lesion is hard to recognize due to inaccessibility and normal-appearing mucosa. With advances in endoscopy, aggressive diagnostic and therapeutic approaches including enteroscopy have recently been performed for small bowel bleeding. We report two cases of massive ileal Dieulafoy lesion bleeding diagnosed and treated successfully by single balloon enteroscopy with a review of the literature.

A Case of Capillary Hemangioma in the Jejunum Detected by Single Balloon Enteroscopy in a Patient with Anemia / 대한소화기내시경학회지

Hemangiomas are uncommon benign vascular tumors that account for up to 10% of all small bowel tumors. The jejunum is the most common location, and gastrointestinal bleeding is a frequent clinical presentation. Histologically, hemangiomas are classified as cavernous, capillary, or mixed types. Capillary hemangiomas are dense collections of capillaries usually with a hyperplastic endothelium. There have been a few cases of small bowel capillary hemangioma revealed by capsule endoscopy and confirmed after surgical resection. But preoperative detection of hemangiomas in the small intestine has not been reported, as far as we know, associated with the use of balloon-assisted enteroscopy. This report describes a 44-year-old male with a small bowel mass considered to be a cause of severe iron deficiency anemia. In this case, we performed capsule endoscopy and single balloon enteroscopy to examine the lesion. The patient then underwent a segmental resection of the jejunum, which confirmed the presence of a capillary hemangioma with surface ulceration.

A Case of Jejunal Extranodal MALT Lymphoma Diagnosed by Single-balloon Enteroscopy / 대한소화기내시경학회지

Small bowel lesions located in long and multiple complex loop configurations were difficult to diagnose early because of vague clinical manifestations and because of the poor diagnostic yield of conventional examination methods. In this setting, double-balloon enteroscopy (DBE) was an epoch-making diagnostic and therapeutic tool for the management of patients with small bowel disease. Single-balloon enteroscopy (SBE), lacking a balloon at the endoscopic tip, is also a useful method for investigating and managing suspected small bowel lesions. Mucosa associated lymphoid tissue (MALT) lymphoma of the small bowel is relatively uncommon and remains a localized disease for long periods in most patients. Recently, we experienced a case of advanced-stage MALT lymphoma in the jejunum. A 60-year old female, with a history of anemia of unknown etiology and who was suspected of having a small bowel lesion, presented with complaints of vague abdominal pain and dizziness. She had undergone SBE via the oral route. She was diagnosed with MALT lymphoma of the jejunum and treated with medical management.
