ABSTRACT
BACKGROUND/AIMS: The endoscopic features of small-bowel gastrointestinal stromal tumors (GISTs) are not well defined. The objective of this study was to describe the endoscopic features of GISTs of the small intestine detected via single-balloon enteroscopy (SBE). MATERIALS AND METHODS: Patients with surgically confirmed small intestinal GISTs from January 2014 to September 2022 were retrospectively analyzed. The hospital's electronic medical record system was used to retrieve the patients' data, including their demographics, clinical symptoms, hemoglobin on admission, endoscopic and computerized tomography findings, clinicopathological findings, and surgical management data. RESULTS: In total, 46 GIST patients (23 men and 23 women) with overt bleeding were included, with a mean age of 52 years (23-80 years). The typical duration of the symptoms was 48 hours. Four patients (8.70%) had lesions in the duodenum, 32 (69.56%) had lesions in the jejunum, 8 (17.39%) had lesions in the ileum, and 2 (4.35%) had lesions around the junction of the jejunum and ileum. Out of the 46 patients, 27 underwent SBE, and GISTs were visualized in 25, while the lesions could not be visualized in the remaining 2. Submucosal round (n = 13), submucosal sessile (n = 8), and invasive/penetrating (n = 4) were among the endoscopic tumor features. Twenty patients exhibited submucosal protuberant lesions, with ulceration, vascular nodules/congestion, or erosion on the surface, and 5 patients presented ulcerative infiltrative lesions. The multiple logistic regression analysis indicated that the invasive/penetrating characteristics of GISTs under SBE evaluation are significantly correlated with the risk level of GIST malignancy (P < .05). CONCLUSION: A variety of endoscopic characteristics could be observed during the preoperative SBE evaluation of small-intestine GISTs.

OBJECTIVES: Single-balloon enteroscopy (SBE) is an effective tool for the detection of small intestine lesions. Because it is conventionally performed by two operators, the efficacy of single-operator SBE method has not yet been elucidated. We aimed to evaluate the diagnostic yield, total enteroscopy rate, procedure time, and complications of single-operator SBE for small intestinal disease. METHODS: This was a single-center, retrospective study including consecutive patients who underwent single-operator SBE for suspicious small intestinal disorders or required therapeutic interventions between December 2014 and January 2019. The SBE procedures were performed by four endoscopists. Diagnostic yield, total enteroscopy rate, procedure time, incubation depth, and complications were analyzed, and stratification analysis was performed. RESULTS: Altogether 922 patients with 1422 SBE procedures were included for analysis, among whom 250, 172, and 500 patients underwent SBE via the oral route, the anal route and a combined route, respectively. The overall diagnostic yield was 78.52% (724/922). And 253 patients achieved total enteroscopy, with a total enteroscopy rate of 56.10%. The average procedure time for the oral and anal routes were 69.28 ± 14.72 min and 64.95 ± 13.87 min, respectively. While the incubation depth was 389.95 ± 131.42 cm and 191.81 ± 83.67 cm, respectively. Jejunal perforation was observed in one patient, which was managed by endoclips. Stratification analysis showed that the diagnostic yield and total enteroscopy rate significantly increased with operation experience together with decreased procedure time. CONCLUSION: Single-operator SBE is effective and safe for the detection of small intestinal lesions, and is easy to master.

Device assisted enteroscopy (DAE) like the double balloon enteroscopy (DBE) and single balloon enteroscopy (SBE) are postulated to ease small bowel examination and performance of therapy. However, studies comparing the effectiveness of these 2 modalities have yielded varying results. The aim of this study is to compare the efficacy and safety of SBE and DBE. We retrospectively reviewed records of patients who underwent DBE (nâ =â 82) or SBE (nâ =â 45) for small bowel exam in our unit from January 2014 to January 2022. Our primary outcomes were to compare the technical success and diagnostic success rates between DBE and SBE. Our secondary outcomes were to compare the therapeutic success, and complication rates. The main indications were suspected GI bleeding (DBE 41.5% vs SBE 48.9%), iron deficiency anemia (DBE 9.8% vs SBE 4.4%) and small bowel lesions (DBE 28.0% vs SBE 44.4%) detected either from prior capsule endoscopy or radiological imaging. Majority of the enteroscopy exam was by antegrade approach (DBE 67.1% vs SBE 77.8%). We found no significant difference in the technical success (DBE 95.1% vs SBE 97.8%, Pâ =â .46), diagnostic success (DBE 69.5% vs SBE 77.8%, Pâ =â .36) and the therapeutic success rate (DBE 63.2% vs SBE 54.3%, Pâ =â .09) between the groups. Complications occurred in 1 case from each group (mucosal tear). None of the complications were major. In patients who underwent enteroscopy, the diagnostic and therapeutic performance of SBE is similar to DBE. Both procedures were safe with low complication rates.

OBJECTIVE: To evaluate whether abdominal compression significantly increased the total enteroscopy rate in single-balloon enteroscopy (SBE). METHODS: Consecutive patients who underwent SBE at 2 hospitals were prospectively included between June 1, 2020, and September 30, 2021. They were randomly divided into an abdominal compression group and a non-abdominal compression group with use of sealed envelopes generated by a computer. Total enteroscopy rates were compared between the groups. RESULTS: The study included 200 patients. The total enteroscopy rates were 73% and 16% in the abdominal compression and non-abdominal compression groups, respectively (relative risk, 13.55; 95% CI, 6.79 to 27.00; P<.001). The total enteroscopy rate was higher in the 70 patients who were identified to have undergone no previous abdominal surgery or small intestinal stenosis than in the 32 patients who had undergone such procedures in the abdominal compression group (84% vs 47%; relative risk, 6.08; 95% CI, 2.36 to 15.67; P<.001). Relevant positive findings were not significantly different between the groups (58% vs 45%; P=.07). Binary logistic regression analysis found abdominal compression to be associated with a better total enteroscopy rate (odds ratio, 16.68; 95% CI, 7.92 to 35.15; P<.001), and the presence of previous abdominal surgery or small intestinal stenosis was associated with difficulty in completing the total enteroscopy procedure (odds ratio, 0.26; 95% CI, 0.12 to 0.58; P<.01). CONCLUSION: Abdominal compression significantly increased the total enteroscopy rate in SBE. Complete total enteroscopy may be challenging in patients with a history of abdominal surgery or small intestinal stenosis.

OBJECTIVE: Recent studies have shown that motorised spiral enteroscopy (MSE) enables deeper and total small bowel evaluation compared with single-balloon enteroscopy (SBE) in suspected Crohn's disease (CD) when analysed per procedure. However, no randomised controlled study has compared bidirectional MSE with bidirectional SBE in suspected CD. DESIGN: Patients with suspected CD requiring small bowel enteroscopy were randomly assigned to either SBE or MSE between May 2022 and September 2022 in a high volume tertiary centre. Bidirectional enteroscopy was done if intended lesion could not be reached on unidirectional study. Comparison was made with regard to technical success (ability to reach lesion), diagnostic yield, depth of maximal insertion (DMI), procedure time and total enteroscopy rates. Depth:time ratio was calculated to avoid confounding for the location of lesion. RESULTS: Among 125 suspected patients with CD (28% female, 18-65 years, median 41 years), 62 and 63 underwent MSE and SBE, respectively. The overall technical success (98.4 %: MSE, 90.5 %: SBE; p=0.11), diagnostic yield (95.2%: MSE; 87.3%: SBE, p=0.2) and procedure time were not significantly different. However, MSE appeared to have higher technical success (96.8% vs 80.7%, p=0.08) in deeper small bowel (distal jejunum/proximal ileum) with higher DMI, higher depth:time ratio and total enteroscopy rates when attempted (77.8% vs 11.1%, p=0.0007). Both the modalities were safe although minor adverse events were more common with MSE. CONCLUSION: MSE and SBE have comparable technical success and diagnostic yield for small bowel evaluation in suspected CD. MSE scores over SBE with regard to deeper small bowel evaluation with complete small bowel coverage and higher depth of insertion in a shorter time. TRIAL REGISTRATION NUMBER: NCT05363930.

INTRODUCTION: Data on the safety and efficacy of double-balloon enteroscopy (DBE) and single-balloon enteroscopy (SBE) are conflicting. We aimed to compare the efficacy and safety of retrograde DBE to SBE. METHODS: We performed a retrospective analysis of all patients who underwent retrograde DBE or SBE at a large tertiary referral center from 2008 to December 2018. Outcomes assessed included technical success, diagnostic yield, therapeutics, depth of insertion, and procedural duration. RESULTS: A total of 523 (403 DBE, 120 SBE) patients underwent retrograde enteroscopy during the study period. The mean age was 59.4 ± 17.24 and 59.57 ± 16.94 years in DBE and SBE groups, respectively. There was no difference in technical success (91.0% vs. 92.5%, P = 0.85), diagnostic yield (40.9% vs. 40.8%, P = 0.95), and therapeutics (17.1% vs. 19.1%, P = 0.61) between DBE and SBE. Compared to SBE, DBE had significantly shorter mean procedure time (26.5 ± 34.5 min vs. 34.8 ± 29.4 min, P = 0.01) and higher maximal depth of insertion from ileocecal valve (108.1 ± 84.1 cm vs. 73.3 ± 63.4 cm, P = 0.001). Safety events were rare and similar in both groups. CONCLUSION: Retrograde DBE is associated with a significantly higher depth of insertion and shorter procedural duration, but similar diagnostic yield and technical success compared to SBE.

OBJECTIVES: Balloon enteroscopy (BE)-assisted endoscopic retrograde cholangiopancreatography (ERCP)-related procedures to resolve acute cholangitis (AC) in patients with surgically altered anatomy (SAA) are limited. There is a lack of evidence on whether the timing of BE-assisted ERCP affects clinical outcomes in patients with AC. This study aimed to evaluate the clinical outcomes of short-type single-balloon enteroscopy (short SBE)-assisted ERCP in patients with SAA and AC. METHODS: Patients with AC who underwent short SBE-assisted ERCP procedures between September 2011 and April 2022 were retrospectively reviewed. The outcomes of procedures undergone at ≤24 h and >24 h were compared. The primary outcome was the length of stay (LOS). RESULTS: Overall, 56 patients underwent procedures at ≤24 h, and 58 patients at >24 h. The procedural success and adverse event rates of short SBE-assisted ERCP were 87.7% (95% confidence interval [CI] 80.3-93.1%) and 4.4% (95% CI 1.4-9.9%), respectively. Patients with severe (Grade III) AC and systemic inflammatory response syndrome were more in early (at ≤24 h) ERCP groups. LOS and median time from ERCP procedures to discharge were shorter in the early group. Procedural success and adverse event rates between both groups had no significant differences. Multivariable linear regression analysis showed that ERCP performed at ≤24 h was associated with shorter LOS, while severe cholangitis and malignant biliary obstruction were associated with longer LOS. CONCLUSIONS: Short SBE-assisted ERCP is effective and safe in patients with SAA and AC. Early procedures seemed to attribute early improvement of general condition, thus shortening the LOS.

BACKGROUND AND AIMS: Both single-balloon enteroscopy (SBE) and the novel motorized spiral enteroscopy (NMSE) are effective techniques for device-assisted enteroscopy (DAE). To date, no study has prospectively compared both modalities in suspected Crohn's disease (CD). METHODS: Patients with suspected CD undergoing either SBE or NMSE between March 2021 and December 2021 in a high-volume tertiary center were prospectively compared for technical success (ability to reach the lesion), diagnostic yield, depth of maximal insertion (DMI), procedure time, and total enteroscopy rates. RESULTS: One hundred seventy-seven patients (37.2% female; aged 7-75 years) with suspected CD underwent 201 DAEs. Technical success was 83% (SBE 81.5% vs NMSE 87.3%, P = .61) and impacted subsequent management in 92% (SBE 88.5% vs NMSE 97.8%, P = .2). Technical success with antegrade NMSE was significantly higher (81.4%) than antegrade SBE (33.3%, P = .007) for lesions in the proximal ileum and beyond. There was no significant difference in the diagnostic yield (SBE 80.8% vs NMSE 83.6%, P = .65). Median procedure time was significantly lower in both antegrade (NMSE, 40 minutes [range, 10-75]; SBE, 60 minutes [range, 20-180]; P < .0001) and retrograde (NMSE, 25 minutes [range, 20-60]; SBE, 60 minutes [range, 20-180]; P < .0001) NMSE. Median DMI was higher with antegrade NMSE (NMSE, 400 cm [range, 70-600]; SBE, 180 cm [range, 60-430]; P < .0001). The total enteroscopy rate was higher with NMSE (37% vs .7% with SBE, P < .0001). All adverse events were mild. CONCLUSIONS: Both NMSE and SBE are safe and effective for small-bowel evaluation in suspected CD. NMSE is superior to SBE with regard to deeper small-bowel evaluation with complete small-bowel coverage and shorter procedure time.

A 72-year-old man was referred to us for evaluation of asymptomatic masses in the liver that had been detected on ultrasonography performed during a physical screening. The level of neuron-specific enolase was elevated (56.97 ng/mL; normal level, 15.7-17.0 ng/mL). Other tumor markers were normal, including alpha fetoprotein, carcinoembryonic antigen and cancer antigen 199. No tumor was found through chest CT scan, gastroscopy and colonoscopy. Abdominal MR demonstrated multiple masses with irregular central necrosis, which appeared as marked hyperintensity on T2WI. Most lesions showed rim-like enhancement at portal venous phase. Pathological examination of tissue obtained by means of percutaneous biopsy indicated that the tumor was composed of small cells which were arranged in nests and trabeculae, the nuclei were round with little cytoplasm, and nuclear division was present (hematoxylin-eosin stain (AU)

BACKGROUND: Few reports have focused on single-balloon enteroscopy (SBE) for evaluation of small bowel Crohn disease (CD) strictures. The aim of this study was to analyze the relationships between peripheral blood inflammatory markers and small bowel CD strictures observed by SBE. MATERIALS AND METHODS: CD patients who underwent SBE between January 2016 and December 2020 were enrolled. The clinical characteristics and peripheral blood inflammatory markers were collected and analyzed to screen for predictive factors significantly associated with small bowel CD strictures. RESULTS: A total of 221 CD patients underwent SBE. The lymphocyte (LC) counts in peripheral blood were significantly lower in the active group (n=178) than in the inactive group (n=43) according to the simple endoscopic score for CD (SES-CD), P =0.011, and was correlated with the SES-CD ( r =-0.134, P =0.047). The LC levels were significantly lower in the stricture group (n=116) than in the nonstricture group (n=105) based on whether small bowel strictures developed, P =0.000, and LC was a risk factor for strictures in the multivariate analysis [hazard ratio (HR), 2.332; 95% CI, 1.102-4.937; P =0.027]. In the subgroup analysis, LC levels notably decreased after stricture aggravation ( P =0.000). Forty-seven patients who underwent small bowel resection underwent SBE at 6 to 12 months after surgery. The LC level was significantly lower in the postoperative patients with strictures ( P =0.025), and LC (HR, 4.444; 95% CI, 1.265-15.617; P =0.020) was a risk of postoperative strictures by univariate analysis, but the age at diagnosis (HR, 6.462; 95% CI, 1.272-22.560; P =0.022) was an independent risk factor by multivariate analysis. CONCLUSION: Peripheral blood LC levels were correlated with SES-CD and gradually decreased as the intestinal stricture increased in small bowel CD patients. The LC level was also significantly lower in the postoperative CD patients with strictures. The level of LC was a risk factor for small bowel strictures. These results suggest that peripheral blood LC could be a novel marker of small bowel CD strictures to guide CD diagnosis and therapy.

BACKGROUND AND OBJECTIVES: Single-balloon enteroscopy (SBE) is a safe and effective modality for the diagnosis and therapeutic treatment of small bowel disorders. However, the efficacy and safety of treating small bowel submucosal tumors (SMTs) with endoscopic submucosal dissection (ESD) or endoscopic full-thickness resection (EFTR) during SBE have not been determined. Hence, the primary aim of this study was to prospectively evaluate the therapeutic yield of SBE in patients with SMTs. PATIENTS AND METHODS: Twenty-one patients with SMTs were enrolled in this study. Regarding the sex distribution, there were 12 men (57.1%) and 9 women (42.9%). Regarding the age distribution, 42.9% of the patients were 60 years old or older and 57.1% of the patients were under 60 years old. The preoperative characteristics of SMTs were summarized and analyzed, the complete resection incidence of SMTs was determined, and the incidence of postoperative complications was collected. ESD-related and EFTR-related complications and the duration of follow-up after leaving hospital were also summarized and analyzed. The efficacy and safety of SMTs treated by ESD or EFTR during SBE were calculated as percentages. RESULTS: Among the 21 patients, 10 (47.6%) underwent EFTR and 11 (52.4%) underwent ESD. The mean diameter of SMTs was 113.50 mm (range: 80 to 160 mm). Anterograde and retrograde SBE were conducted in 11 and 10 patients, respectively. The mean follow-up time was 49.3 days (range: 6.0 to 129 d). The complete resection rate of SMTs was 100%. The complete suture rate of SMTs wound was 100%. The SMTs pathology of all patients showed that the margin-negative (R0) resection was 100%. The incidence of physical discomfort complications (ie, infection/fever, abdominal pain, and abdominal distension) of ESD and EFTR was 5 (23.8%) on day 1, 1 (4.8%) on day 2, and 1 (4.8%) on day 3 after operation. Only 1 (4.8%) patient with EFTR had abdominal pain on the sixth day after leaving hospital, and the visual analog scale/score was 1 point, meaning the pain was easily tolerated by the patient. Twenty (95.2%) patients had no abdominal discomfort after leaving hospital. No patients needed additional surgery because of complications after ESD or EFTR during SBE. CONCLUSIONS: This preliminary study showed that SMTs can be safely and effectively treated by ESD or EFTR during SBE, particularly SMTs <160 mm in diameter.

RATIONALE: Endoscopic treatment of a pancreatic pseudocyst complicated by pancreaticojejunostomy (PJ) stricture is challenging. PATIENT CONCERNS: A 76-year-old woman presented with worsening abdominal pain and dyspepsia. She had been receiving adjuvant chemotherapy (capecitabine and cisplatin) for 4 months after pylorus-preserving pancreaticoduodenectomy (PPPD) for the treatment of extrahepatic cholangiocarcinoma. DIAGNOSES: Laboratory findings included elevated serum amylase (145 U/L) and lipase (437 U/L) levels. Abdominal computed tomography (CT) showed a pancreatic pseudocyst of approximately 3 cm in size and pancreatic duct dilatation in the remnant pancreas. According to the Response Evaluation Criteria in Solid Tumors, cholangiocarcinoma is a stable disease. INTERVENTIONS AND OUTCOMES: Endoscopic drainage of the pancreatic pseudocyst was planned. Single-balloon enteroscopy (SBE)-guided endoscopic retrograde pancreatography (ERP) with endoscopic ultrasonography (EUS) using a mini probe demonstrated a membranous PJ stricture and a pancreatic pseudocyst. Endoscopic pseudocyst drainage using a 7-Fr plastic stent was successfully performed after needle-knife incision of the PJ stricture. Follow-up abdominal CT after 3 weeks showed complete resolution of the pseudocyst. Chemotherapy was resumed. LESSONS: SBE-guided ERP with EUS using a mini probe may be an effective and safe treatment in a patient with a pancreatic pseudocyst complicated by membranous PJ stricture after PPPD.

Aim: Stricture is one of the main complications of Crohn's disease (CD). Among the main conservative therapeutic alternatives, endoscopic balloon dilation (EBD) of the strictures stands out, which can improve the symptoms and delay or even avoid the need for more surgeries. The main aim of this study was to evaluate the efficacy of the EBD in CD patients with post-surgical anastomotic strictures from a previous surgery. Patients and methods: An observational study of a cohort of 32 patients with CD who underwent EBD due to uncomplicated strictures at a tertiary hospital, since 2009. Demographic, clinical and disease variables, medical treatments and previous surgeries and types, analytical variables at the time of dilation, number of dilations, complications and need for subsequent surgery were collected by searching data in clinical records. Results: Thirty-two patients were included, performing a total of 63 endoscopic dilations. A technical success of 63.5%, a therapeutic success by dilation of 58.75% and a therapeutic success per patient of 62.5% were achieved. Regarding complications, the percentage of post-dilation adverse events was 3.2% and post-dilation incidents were 4.8%. Thirty EBD did not need any medical treatment modification, 9 EBD remained untreated and 12 EBD required further surgery. The length of the strictures, but not the ongoing treatment, was the only statistically significant factor of therapeutic success by dilation and per patient. Conclusions: EBD seems a safe technique in short post-surgical strictures, can avoid the need for new surgery and prevents unnecessary immunosuppression in patients with CD anastomotic strictures.(AU)
Objetivo: La estenosis es una de las principales complicaciones de la enfermedad de Crohn (EC). La dilatación endoscópica con balón (DEB) es una de las principales alternativas terapéuticas para mejorar los síntomas y retrasar o evitar nuevas cirugías. El objetivo principal fue evaluar la eficacia de la DEB en pacientes con EC y estenosis anastomótica posquirúrgica. Pacientes y métodos: Estudio observacional de una cohorte de 32 pacientes con EC tratados con DEB por estenosis no complicadas en un hospital terciario, desde 2009. Se recogieron variables demográficas, clínicas y de la enfermedad, tratamientos médicos y cirugías previas, variables analíticas en el momento de la dilatación, número de dilataciones, complicaciones y necesidad de cirugía posterior mediante la búsqueda de datos en las historias clínicas. Resultados: Se incluyó a 32 pacientes, con un total de 63 dilataciones endoscópicas. Se obtuvo un éxito técnico del 63,5%, un éxito terapéutico por dilatación del 58,75% y un éxito terapéutico por paciente del 62,5%. En cuanto a las complicaciones, el porcentaje de eventos adversos fue del 3,17% y de incidentes del 4,8%. No necesitaron ninguna modificación del tratamiento médico 30 DEB, 9 permanecieron sin tratamiento y 12 requirieron una nueva cirugía. La longitud de la estenosis, pero no el tratamiento en curso, fue el único factor estadísticamente significativo del éxito terapéutico por dilatación y por paciente. Conclusiones: La DEB parece una técnica segura en las estenosis posquirúrgicas cortas, ya que podría evitar nuevas cirugías y evitar la inmunosupresión innecesaria en pacientes con estenosis anastomóticas de EC.(AU)

BACKGROUND: Endoscopic access to the targeted site is a major challenge for the endoscopic retrograde cholangiopancreatography (ERCP) in patients undergoing Roux-en-Y (R-Y) reconstruction after total or subtotal gastrectomy. We aimed to evaluate the feasibility, reproducibility, and safety of mechanistic loop resolution strategies using a short-type single-balloon enteroscopy (short SBE) system. METHODS: Between February 2020 and March 2022, consecutive patients with a previous R-Y gastrectomy requiring ERCP were prospectively enrolled. Different mechanistic loop resolution strategies for two-dimensional loops, three-dimensionally rotated loops, and loops making a cane or S-shape were applied during the SBE approach. RESULTS: Forty-three short SBE-ERCP procedures were performed on 37 patients, with an approach success rate of 100.0% (43/43). The mean time to reach the jejunojejunal anastomosis and target site were 8.0 (6.0-11.0) minutes and 26.0 (16.0-36.0) minutes, respectively. The major challenges for the approach were the cane or S-shaped loop in the jejunojejunal anastomosis or Treitz ligament. The retroflex positioning of a SBE in front of the papilla was achieved in 86.0% (37/43), and the cannulation success rate in patients with an intact papilla was 90.9% (30/33). The initial, overall therapeutic successes, median total procedure time, and adverse event rate were 87.8%, 92.7%, 77.0 (IQR 56-100.5) minutes, and 11.6%, respectively. CONCLUSIONS: Short SBE-ERCP using standardized mechanistic loop resolution strategies is effective and reproducible in patients with R-Y reconstruction after gastrectomy. TRIAL REGISTRATION: ClinicalTrial.gov (NCT04847167).

Background: Little is known about the efficacy and safety of single-balloon enteroscopy (SBE) in patients with Peutz-Jeghers syndrome (PJS). The aim of this study was to assess the efficacy and safety of SBE for the treatment of small bowel polyps in patients with PJS. Methods: We conducted a single-center observational study, which included all patients diagnosed with PJS who underwent SBE for polypectomy between January 2018 and March 2021. Complete treatment was defined as the absence of polyps ≥10 mm after SBE resection. The clinical records were retrospectively reviewed. Results: 102 patients (including 40 men and 62 women) with a mean age of 28.7 years (range 13-55 y) were enrolled in our study. The intubation depth via the oral approach of patients with a history of laparotomy was significantly shorter than that of the patients without a history of laparotomy ([241.6 ± 64.2] cm vs [280.9 ± 40.2] cm, P=0.008). The maximum size of the resected polyps via anus during the second hospitalization was significantly smaller than that during the first hospitalization ([2.25 ± 1.29] cm vs [4.26 ± 3.51] cm, P=0.032). For patients with total enteroscopy, the complete treatment rate was 98% (49/50). For patients without total enteroscopy, all polyps larger than 10 mm in the examined segment of small bowel were resected successfully. Complications occurred in 10 of 129 hospitalizations (delayed bleeding in 4, perforation in 3, and acute pancreatitis in 3). Conclusions: SBE is effective and safe for resection of small bowel polyps in patients with PJS.
