Endoscopic treatment of biliopancreatic pathology in patients with Whipple's pancreaticoduodenectomy surgical variants: Lessons learned from single-balloon enteroscopy-assisted ERCP

Background: Endoscopic treatment of biliopancreatic pathology is challenging due to surgically altered anatomy after Whipple's pancreaticoduodenectomy. This study aimed to evaluate the feasibility and safety of single-balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography(SBE-ERCP) to treat biliopancreatic pathology in patients with Whipple's pancreaticoduodenectomy surgical variants. Methods: We retrospectively analyzed 106 SBE-ERCP procedures in 46 patients with Whipple's variants. Technical and clinical success rates and adverse events were evaluated. Results: Biliary SBE-ERCP was performed in 34 patients and pancreatic SBE-ERCP in 17, including 5 with both indications. From a total of 106 SBE-ERCP procedures, 76 were biliary indication with technical success rate of 68/76(90%) procedures and clinical success rate of 30/34(88%) patients. Mild adverse event rate was 8/76(11%), without serious adverse events. From a total of 106 SBE-ERCP procedures, 30 were pancreatic indication with technical success rate of 24/30(80%) procedures( P = 0.194 vs. biliary SBEERCP) and clinical success rate of 11/17(65%) patients( P = 0.016 vs. biliary SBE-ERCP). Mild adverse event rate was 6/30(20%)( P = 0.194 vs. biliary SBE-ERCP), without serious adverse events. After SBE-ERCP failure, endoscopic ultrasound-guided drainage, percutaneous drainage and redo surgery were alternative therapeutic options. Conclusions: Biliopancreatic pathology after Whipple's pancreaticoduodenectomy variants can be treated using SBE-ERCP without serious adverse events. Technical and clinical success rates are high for biliary indications, whereas clinical success rate of pancreatic indications is significantly lower. SBE-ERCP can be considered as first-line treatment option in this patient group with surgically altered anatomy.

Capsule endoscopy and single-balloon enteroscopy in small bowel diseases: Competing or complementary?

AIM To evaluate diagnostic yields of capsule endoscopy(CE) and/or single-balloon enteroscopy(SBE) in patients with suspected small bowel diseases.METHODS Were trospectively analyzed 700 patients with suspected small bowel diseases from September 2010 to March 2016. CE, SBE, or SBE with prior CE was performed in 401, 353, and 47 patients, respectively. Data from clinical and endoscopy records were collected for analysis. Indications, procedure times, diagnostic yields, and complications were summarized and evaluated.RESULTS The overall diagnostic yield for the CE group was 57.6%. The diagnostic yield of CE in patients with obscure gastroin testinal bleeding(OGIB) was significantly greater than that in patients with no bleeding(70.5% vs 43.8%, P < 0.01). The overall diagnostic yield of SBE was 69.7%. There was no difference in the diagnostic yield of SBE between patients with OGIB and those with no bleeding(72.5% vs 68.9%, P = 0.534). Forty-seven patients underwent CE prior to SBE. Among them, the diagnostic yield of SBE with positive findings on prior CE was 93.3%. In addition, SBE detected two cases with superficial ulcer and erosive lesions in the small bowel, which were missed by CE. However, one case with lymphoma and two with Crohn's disease were not confirmed by SBE. The rate of capsule retention was 2.0%. There were no significant complications during or after SBE examinations.CONCLUSION SBE is a safe and effective technique for diagnosing small bowel diseases. SBE with prior CE seemed to improve the diagnostic yield of small bowel diseases.

Emergent single-balloon enteroscopy for overt bleeding of small intestinal vascular malformation

A 28-year-old man presented with anemia symptoms and intermittent tarry stool passage for three days. No stigmata of hemorrhage were identified using esophagogastroduodenoscopy, ileocolonoscopy, and contrast-enhanced computed tomography. He then developed massive tarry stool passage with profound hypovolemic shock and hypoxic respiratory failure. Emergent angiography revealed active bleeder, probably from the jejunal branches of the superior mesenteric artery, but embolization was not performed due to possible subsequent extensive bowel ischemia. His airway was secured via endotracheal intubation with ventilator support, and emergent antegrade singleballoon enteroscopy was performed at 8 h after clinical overt bleeding occurrence; the procedure revealed a 2-cm pulsating subepithelial tumor with a protrudingblood plug at the distal jejunum. Laparoscopic segmental resection of the jejunum with end-to-end anastomosis was performed after emergent endoscopic tattooing localization. Pathological examination revealed a vascular malformation in the submucosa with an organizing thrombus. He was uneventfully discharged 5 d later. This case report highlights the benefit of early deep enteroscopy for the treatment of small intestinal bleeding.

Comparison between double-balloon and single-balloon enteroscopy in therapeutic ERC after Roux-en-Y entero-enteric anastomosis

AIM:To compare the efficacy of double-balloon enteroscopy (DBE) and single-balloon enteroscopy (SBE) in therapeutic endoscopic retrograde cholangiography (ERC) in patients with Roux-en-Y entero-enteric anastomosis.METHODS:Retrospective analysis of our patient cohort revealed 4 patients with enterobiliary anastomosis and Roux-en-Y entero-enteric anastomosis who underwent repeated ERC with DBE and SBE because of recurrent cholangitis.RESULTS:A total of 38 endoscopic retrograde cholangiopancreatography procedures were performed in 25 patients with Roux-en-Y entero-enteric anastomosis.DBE was used in 29 procedures and SBE in 9.The 4 patients who underwent repeated ERC with DBE and SBE suffered from recurrent cholangitis due to stenosis of the enterobiliary anastomosis.ERC was performed repeatedly to achieve balloon dilation with/without biliary stone extraction and multiple stent placement at the level of the enterobiliary anastomosis.In all 4 patients DBE and SBE were equally successful.Compared to DBE,SBE was equally effective in passing the Roux-en-Y entero-enteric anastomosis,reaching the enterobiliary anastomosis and performing therapeutic ERC.CONCLUSION:This retrospective comparison shows that DBE and SBE are equally successful in the performance of therapeutic ERC at the level of the enterobiliary anastomosis after Roux-en-Y entero-enteric anastomosis.

Current status of single-balloon enteroscopy: Insertability and clinical applications

The single-balloon enteroscopy(SBE) system was launched in 2007, proposed as a simpler method than double-balloon enteroscopy(DBE). Controversy surrounds whether the SBE system has the same insertability as DBE. However, many methods have been proposed to improve the depth of insertion with the SBE system, involving several techniques and endoscopic accessories. SBE is used for investigating not only small bowel diseases, but also diseases of the pancreatobiliary and colonic structures. SBE is a necessary advancement for many endoscopic procedures and applications in modern clinical practice. In our review, we summarized the current literature concerning the insertability of SBE and described the technical aspects of improving the rate of deep insertion in SBE procedures. In addition, the recent applications of SBE to diseases besides those of the small bowel are described.

Evaluation of the diagnostic and therapeutic utility of retrograde through-the-scope balloon enteroscopy and single-balloon enteroscopy

BACKGROUND Retrograde single balloon enteroscopy(SBE)is a minimally invasive procedure which is less frequently performed compared with antegrade SBE.There are few studies on the retrograde through-the-scope enteroscopy(TTSE),a novel technique for evaluation of the small bowel.AIM To compare the clinical utility and safety of retrograde TTSE with retrograde SBE.METHODS Clinical data and complications of retrograde TTSE(2014-2018)and retrograde SBE(2011-2018)performed in a community hospital were reviewed and presented as mean±SD or frequency(%)and compared using proper statistical tests.Technical success was defined as insertion of the enteroscope>20 cm beyond ileocecal valve.RESULTS Data obtained from 54 retrograde SBE in 49 patients and 27 retrograde TTSE in 26 patients were studied.The most common indication for retrograde enteroscopy was iron deficiency anemia(41 patients)followed by gastrointestinal bleeding(37 patients),and chronic diarrhea(7 patients).The duration of retrograde SBE procedure(91.9±34.2 min)was significantly longer compared with retrograde TTSE(70.5±30.7 min)(P=0.04).Technical success was comparable in TTSE[23/27(85.2%)]and SBE[41/54(75.9%)(P=0.33)].The mean depth of insertion beyond the ileocecal valve in retrograde SBE(92.5±70.0 cm)tended to be longer compared with retrograde TTSE(64.6±49.0 cm)(P=0.08).No complication was observed in this study.CONCLUSION Both retrograde TTSE and retrograde SBE are feasible and safe.Retrograde TTSE takes a shorter time and has a comparable technical success with SBE.TTSE has a lower capacity of small bowel insertion.

ConservativeapproachinPeutz-JeghersSyndrome:Single-balloon enteroscopyandsmallbowelpolypectomy

AIM: To assess the usefulness of the balloon assisted enteroscopy in preventing surgical intervention in pa-tients with Peutz-Jeghers syndrome (PJS) having a small bowel large polyps. METHODS: Seven consecutive asymptomatic pts(age 15-38 years) with PJS have been collected; six under-went polypectomy using single balloon enteroscopy(Olympus SIF Q180) with antegrade approach using push and pull technique. SBE system consists of the SIF-Q180 enteroscope, an overtube balloon control unit(OBCU Olympus Balloon Control Unit) and a dispos-able silicone splinting tube with balloon(ST-SB1). All procedures were performed under general anesthesia. Previously all pts received wireless capsule endos-copy(WCE). Prophylactic polypectomy was reservedmainly in pts who had polyps > 15 mm in diameter. The balloon is inflated and deflated by a balloon control unit with a safety pressure setting range from-6.0 kPa to +5.4 kPa. Informed consent has been obtained from pts or parents for each procedure.RESULTS: Six pts underwent polypectomy of small bowel polyps; in 5 pts a large polyp > 15 mm(range 20-50 mm in diameter) was resected; in 1 patient with WCE negative, SBE was performed for previous surgi-cal resection of gastrointestinal stromal tumors. In 2 pts endoscopic clips were placed due to a polypectomy. No surgical complication have been reported. SBE with resection of small bowel large polyps in PJS pts was useful to avoid gastrointestinal bleeding and emergency laparotomy due to intestinal intussuscep-tions. No gastrointestinal tumors were found in sub-sequent enteroscopic surveillance in all seven pts. In order surveillance, all pts received WCE, upper en-doscopy, ileocolonoscopy every 2 years. No pts had extraintestinal malignant lesions. SBE was performed when WCE was positive for significant polyps(> 15 mm).CONCLUSION: The effective of prophylactic polyp-ectomy of small bowel large polyps(> 15 mm) could be the first line treatment for conservative approach in management of PJS patients.

Device-assisted enteroscopy: Are we ready to dismiss the spiral?

Motorized spiral enteroscopy(MSE)is the latest advance in device-assisted enteroscopy.Adverse events related to MSE were discussed in a recent large systematic review and meta-analysis and were directly compared with those of balloon enteroscopy in a case-matched study and a randomized controlled trial.Following the real-life application of MSE,an unexpected safety issue emerged regarding esophageal injury and the technique has been withdrawn from the global market,despite encouraging results in terms of diagnostic and therapeutic yield.We conducted an Italian multicenter real-life prospective study,which was prematurely terminated after the withdrawal of MSE from the market.The primary goals were the evaluation of MSE performance(both diagnostic and therapeutic)and its safety in routine endoscopic practice,particularly in the early phase of introduction in the endoscopic unit.A subanalysis,which involved patients who underwent MSE after unsuccessful balloon enteroscopy,demonstrated,for the first time,the promising performance of MSE as a rescue procedure.Given its remarkable performance in clinical practice and its potential role as a backup technique following a previously failed enteroscopy,it may be more appropriate to refine and enhance MSE in the future rather than completely abandoning it.

Ileal gallstone obstruction:Single-balloon enteroscopic removal

Gallstone-induced ileus is a rare complication of cholelithiasis.Since localization of gallstones impacted in the small bowel,especially in the ileum,prevents access by conventional endoscopy in most cases,the mainstay of treatment remains surgical.Recent invention of double-and single-balloon enteroscopy has added much to the ability of imaging the small bowel and enables endoscopically directed therapy.Herein,for the first time,we report a successful endoscopic calculus removal via peroral single-balloon enteroscopy in an 81-year-old woman suffering from gallstone ileus of the ileum.

Single-balloon and spiral enteroscopy may have similar diagnostic and therapeutic yields to double-balloon enteroscopy:Results from a meta-analysis of randomized controlled trials and prospective studies

BACKGROUND Double-balloon,single-balloon,and spiral enteroscopy(DBE,SBE,and SE)have revolutionized the management of intestinal diseases.However,evidence about efficacies of these methods is lacking.We aimed to conduct a meta-analysis comparing the clinical outcomes among DBE,SBE,and SE.METHODS We searched randomized controlled trials and prospective studies in MEDLINE,PubMed,EMBASE,Cochrane Library,and Chinese CQVIP database.Studies referencing the comparison of at least two of these three methods were included.Primary outcome was diagnostic yield.Other outcomes were therapeutic yield,total enteroscopy,examination time,time to maximum insertion,and depth of maximal insertion(DMI).RESULTS Eleven studies including 727 patients were identified:DBE vs SE(n=6),DBE vs SBE(n=4),and SBE vs SE(n=1).The diagnostic and therapeutic yields did not differ significantly when comparing DBE with SE[odds ratio(OR)=1.19,95%confidence interval(CI):0.68-2.08;OR=1.17,95%CI:0.61-2.23]and DBE with SBE(OR=0.85,95%CI:0.55-1.33;OR=1.71,95%CI:0.64-4.60).Total enteroscopy,examination time,time to maximum insertion,and DMI were similar between SBE and DBE.DBE was superior to SE with regard to DMI[mean difference(MD)=36.76,95%CI:5.09-68.43],with longer time to maximum insertion(MD=15.14,95%CI:12-18.27)and examination time(MD=12.98,95%CI:9.57-16.38).CONCLUSION DBE and SBE have similar clinical outcomes.Compared with DBE,SE seems to have similar diagnostic and therapeutic yields,but shorter procedural time in cost of less depth of insertion.SE needs further evaluation vs SBE.DBE is recommended for complete enteroscopy.

Computed tomography three-dimensional reconstruction in the diagnosis of bleeding small intestinal polyps:A case report

BACKGROUND Computed tomography(CT)small bowel three-dimensional(3D)reconstruction is a powerful tool for the diagnosis of small bowel disease and can clearly show the intestinal lumen and wall as well as the outside structure of the wall.The horizontal axis position can show the best adjacent intestinal tube and the lesion between the intestinal tubes,while the coronal position can show the overall view of the small bowel.The ileal end of the localization of the display of excellent,and easy to quantitative measurement of the affected intestinal segments,the sagittal position for the rectum and the pre-sacral lesions show the best,for the discovery of fistulae is also helpful.Sagittal view can show rectal and presacral lesions and is useful for fistula detection.It is suitable for the assessment of inflammatory bowel disease,such as assessment of disease severity and diagnosis and differential diagnosis of the small bowel and mesenteric space-occupying lesions as well as the judgment of small bowel obstruction points.CASE SUMMARY Bleeding caused by small intestinal polyps is often difficult to diagnose in clinical practice.This study reports a 29-year-old male patient who was admitted to the hospital with black stool and abdominal pain for 3 months.Using the combination of CT-3D reconstruction and capsule endoscopy,the condition was diagnosed correctly,and the polyps were removed using single-balloon enteroscopyendoscopic retrograde cholangiopancreatography without postoperative complications.CONCLUSION The role of CT-3D in gastrointestinal diseases was confirmed.CT-3D can assist in the diagnosis and treatment of gastrointestinal diseases in combination with capsule endoscopy and small intestinal microscopy.

Intermittent melena and refractory anemia due to jejunal cavernous lymphangioma:A case report

BACKGROUND Lymphangiomas in the gastrointestinal tract are extremely rare in adults.As a benign lesion,small intestine lymphangiomas often remain asymptomatic and pose challenges for definitive diagnosis.However,lymphangiomas can give rise to complications such as abdominal pain,bleeding,volvulus,and intussusception.Here,we report a case of jejunal cavernous lymphangioma that presented with intermittent melena and refractory anemia in a male adult.CASE SUMMARY A 66-year-old man presented with intermittent melena,fatigue and refractory anemia nine months prior.Esophagogastroduodenoscopy and colonoscopy were performed many times and revealed no apparent bleeding.Conservative management,including transfusion,hemostasis,gastric acid secretion inhibition and symptomatic treatment,was performed,but the lesions tended to recur shortly after surgery.Ultimately,the patient underwent capsule endoscopy,which revealed a more than 10 cm lesion accompanied by active bleeding.After singleballoon enteroscopy and biopsy,a diagnosis of jejunal cavernous lymphangioma was confirmed,and the patient underwent surgical resection.No complications or recurrences were observed postoperatively.CONCLUSION Jejunal cavernous lymphangioma should be considered a cause of obscure gastrointestinal bleeding.Capsule endoscopy and single-balloon enteroscopy can facilitate diagnosis.Surgical resection is an effective management method.

Characteristics and prognosis of small bowel tumors:A retrospective study

BACKGROUND Small bowel tumors(SBTs)are a heterogeneous group of difficult-to-diagnose tumors that account for 2%-5%of all gastrointestinal tumors.Single-balloon enteroscopy greatly enhances the diagnosis and treatment of SBTs.However,few epidemiological studies have been conducted in Taiwan to determine the clinical profile of SBTs.AIM To investigate the clinical characteristics,managements and prognosis of SBTs in a medical center in Taiwan.METHODS The study enrolled 51 patients aged 58.9±8.8 years(range,22-93)diagnosed with SBTs from November 2009 to July 2021.We retrospectively recorded clinical characteristics,indications,endoscopic findings,pathological results,management,and outcomes for further analysis.RESULTS A male preponderance was observed(56.8%).The most common indications were suspected small intestinal tumors(52.9%)and obscure gastrointestinal bleeding(39.2%).The most common tumor location was the ileum(41.2%).The performance of imaging studies(P=0.004)and the types of findings(P=0.005)differed significantly between malignant and benign SBTs.The most frequent imaging finding was a small intestinal mass(43.1%).The top three malignant tumor types were gastrointestinal stromal tumors(GISTs),adenocarcinomas,and lymphomas.Moreover,the proportions of benign and malignant tumors were 27.5%and 72.5%,respectively.The survival rates of patients with malignant tumors in the GIST and non-GIST groups differed significantly(P=0.015).Kaplan–Meier survival analysis showed a significant difference in survival between patients in the malignant and benign groups(P=0.04).All patients with lymphoma underwent chemotherapy(n=7/8,87.5%),whereas most patients with GISTs underwent surgery(n=13/14,92.8%).CONCLUSION Patients with GISTs have a significantly higher survival rate than those with other malignant SBTs.Therefore,a large-scale nationwide study is warranted to evaluate the population-based epidemiology of SBTs.

右美托咪定辅助全身麻醉对老年无痛肠镜检查患者血流动力学及认知功能的影响

目的探讨右美托咪定(DEX)辅助全身麻醉对老年无痛肠镜检查患者血流动力学及认知功能的影响。方法将2020年7月至2022年2月在焦作市第二人民医院门诊手术室行无痛肠镜检查的老年患者180例,根据随机数字表法分为对照组(n=90)和观察组(n=90)。对照组患者给予常规全身麻醉(舒芬太尼+丙泊酚麻醉诱导,丙泊酚麻醉维持);观察组患者在术前准备后加用DEX辅助全身麻醉。比较2组患者的血流动力学指标[平均动脉压(MAP)、心率(HR)]、全麻用药量、苏醒时间、认知功能[简易精神状况检查量表(MMSE)]评分、不良反应发生率。结果2组患者麻醉前(T0)各项指标的差异均无统计学意义(P>0.05);与T0时比较,麻醉10 min后(T1)、肠镜达回盲部(T2)、检查后退镜(T3)、术后10 min(T4)时两组患者的MAP、HR均显著降低,但观察组患者在T1、T2、T3、T4时的MAP、HR均显著高于对照组(P<0.05)。与对照组比较,观察组患者的全麻用药量显著降低,苏醒时间显著缩短,术后1、2、3 d的MMSE评分显著升高,认知功能障碍发生率及不良反应发生率均显著降低(P<0.05)。结论DEX可有效改善老年无痛肠镜检查患者的血流动力学及认知功能,减少全麻用药量,缩短患者苏醒时间,且安全性较好。

Treatment of hemolymphangioma by robotic surgery: A case report

BACKGROUND Hemolymphangioma of the jejunum is rare and lacks clinical specificity,and can manifest as gastrointestinal bleeding,abdominal pain,and intestinal obstruction.Computed tomography,magnetic resonance imaging,and other examinations show certain characteristics of the disease,but lack accuracy.Although capsule endoscopy and enteroscopy make up for this deficiency,the diagnosis also still re-quires pathology.CASE SUMMARY A male patient was admitted to the hospital due to abdominal distension and abdominal pain,but a specific diagnosis by computed tomography examination was not obtained.Partial resection of the small intestine was performed by robotic surgery,and postoperative pathological biopsy confirmed the diagnosis of hemo-lymphangioma.No recurrence in the follow-up examination was observed.CONCLUSION Robotic surgery is an effective way to treat hemolymphangioma through minima-lly invasive techniques under the concept of rapid rehabilitation.

老年病人经肛双气囊小肠镜进镜效率及其影响因素研究

目的 探讨老年病人经肛双气囊小肠镜检查(DBE)的进镜效率及影响因素。方法 纳入2022年3月至2023年10月在南京医科大学第一附属医院老年内镜中心行经肛DBE的180例60岁以上的老年病人,收集其一般资料,采用渥太华肠道准备评分(OBPS)评估病人肠道准备质量,统计经肛DBE的进镜深度及操作时间,计算进镜效率,根据进镜效率分为高效组和低效组,分析进镜效率的影响因素。结果 单因素分析显示,手术部位、息肉或憩室疾病、盲肠插管时间(CIT)与经肛DBE进镜效率相关。多因素Logistic回归分析显示,息肉等病史、手术部位及CIT是经肛DBE进镜效率的独立影响因素,有下腹部手术史的病人进镜效率较低。结论 下腹部手术史、息肉或憩室疾病、CIT长会降低老年病人经肛DBE的进镜效率。
