A new technique to preserve the uterus in patients with placenta accreta spectrum disorders.

BACKGROUND: Placenta accreta spectrum disorders are associated with substantial maternal morbidity and mortality. Despite a preoperative diagnosis, the rate of complications remains high, and the condition is generally associated with the need for a hysterectomy. OBJECTIVE: This study aimed to evaluate the outcomes of a new uterine-preserving technique (called the combined approach, including surgical hemostasis, bilateral ligation of the descending branches of the uterine arteries, and hemostatic external supraplacental stitch with the use of the Zhukovsky double-balloon tamponade in patients with placenta accreta spectrum disorders) during cesarean delivery in women with placenta accreta spectrum disorders vs the surgical technique used until 2014. STUDY DESIGN: This retrospective cohort study included 147 patients with placenta accreta spectrum disorders who were divided into 2 groups: the study group (n=95) is to undergo cesarean delivery using the combined approach, and the control group (n=52) is to undergo the surgical technique used until 2014, which included bilateral uterine artery ligation, which is the transfusion of plasma, red blood cells, platelets, and protease inhibitors. RESULTS: The volume of blood loss was 1.5-fold lower (P=.0010), the number of blood transfusions was 5.1-fold lower (P=.026), and the rate of bladder injuries was 19-fold lower (P=.012) in the study group than that in the control group. The duration of hospital stay after delivery was 4 days lesser (P=.001) and the number of hysterectomies was 4.5-fold lower in the study group than in the control group (P=.023). The study groups did not differ in terms of placenta accreta spectrum type. CONCLUSION: The combined approach during cesarean delivery proved to be more effective than the surgical technique used until 2014 in reducing the number of hysterectomies, blood loss volume, number of blood transfusions, and duration of hospital stay in patients with placenta accreta spectrum disorders.

Methods for the induction of labor: efficacy and safety.

This review assessed the efficacy and safety of pharmacologic agents (prostaglandins, oxytocin, mifepristone, hyaluronidase, and nitric oxide donors) and mechanical methods (single- and double-balloon catheters, laminaria, membrane stripping, and amniotomy) and those generally considered under the rubric of complementary medicine (castor oil, nipple stimulation, sexual intercourse, herbal medicine, and acupuncture). A substantial body of published reports, including 2 large network meta-analyses, support the safety and efficacy of misoprostol (PGE1) when used for cervical ripening and labor induction. Misoprostol administered vaginally at doses of 50 µg has the highest probability of achieving vaginal delivery within 24 hours. Regardless of dosing, route, and schedule of administration, when used for cervical ripening and labor induction, prostaglandin E2 seems to have similar efficacy in decreasing cesarean delivery rates. Globally, although oxytocin represents the most widely used pharmacologic agent for labor induction, its effectiveness is highly dependent on parity and cervical status. Oxytocin is more effective than expectant management in inducing labor, and the efficacy of oxytocin is enhanced when combined with amniotomy. However, prostaglandins administered vaginally or intracervically are more effective in inducing labor than oxytocin. A single 200-mg oral tablet of mifepristone seems to represent the lowest effective dose for cervical ripening. The bulk of the literature assessing relaxin suggests this agent has limited benefit when used for this indication. Although intracervical injection of hyaluronidase may cause cervical ripening, the need for intracervical administration has limited the use of this agent. Concerning the vaginal administration of nitric oxide donors, including isosorbide mononitrate, isosorbide, nitroglycerin, and sodium nitroprusside, the higher incidence of side effects with these agents has limited their use. A synthetic hygroscopic cervical dilator has been found to be effective for preinduction cervical ripening. Although a pharmacologic agent may be administered after the use of the synthetic hygroscopic dilator, in an attempt to reduce the interval to vaginal delivery, concomitant use of mechanical and pharmacologic methods is being explored. Combining the use of a single-balloon catheter with dinoprostone, misoprostol, or oxytocin enhances the efficacy of these pharmacologic agents in cervical ripening and labor induction. The efficacy of single- and double-balloon catheters in cervical ripening and labor induction seems similar. To date, the combination of misoprostol with an intracervical catheter seems to be the best approach when balancing delivery times with safety. Although complementary methods are occasionally used by patients, given the lack of data documenting their efficacy and safety, these methods are rarely used in hospital settings.

A newly developed deep learning-based system for automatic detection and classification of small bowel lesions during double-balloon enteroscopy examination.

BACKGROUND: Double-balloon enteroscopy (DBE) is a standard method for diagnosing and treating small bowel disease. However, DBE may yield false-negative results due to oversight or inexperience. We aim to develop a computer-aided diagnostic (CAD) system for the automatic detection and classification of small bowel abnormalities in DBE. DESIGN AND METHODS: A total of 5201 images were collected from Renmin Hospital of Wuhan University to construct a detection model for localizing lesions during DBE, and 3021 images were collected to construct a classification model for classifying lesions into four classes, protruding lesion, diverticulum, erosion & ulcer and angioectasia. The performance of the two models was evaluated using 1318 normal images and 915 abnormal images and 65 videos from independent patients and then compared with that of 8 endoscopists. The standard answer was the expert consensus. RESULTS: For the image test set, the detection model achieved a sensitivity of 92% (843/915) and an area under the curve (AUC) of 0.947, and the classification model achieved an accuracy of 86%. For the video test set, the accuracy of the system was significantly better than that of the endoscopists (85% vs. 77 ± 6%, p < 0.01). For the video test set, the proposed system was superior to novices and comparable to experts. CONCLUSIONS: We established a real-time CAD system for detecting and classifying small bowel lesions in DBE with favourable performance. ENDOANGEL-DBE has the potential to help endoscopists, especially novices, in clinical practice and may reduce the miss rate of small bowel lesions.

Characterization of primary small intestinal lymphoma: a retrospective study based on double balloon endoscopy.

BACKGROUND: The diagnosis of primary small intestinal lymphoma (PSIL) is difficult. This study aimed to evaluate the clinical, radiological and endoscopic characteristics of PSIL and provide clue for diagnosis. METHODS: A total of 30 patients diagnosed with PSIL who underwent double balloon endoscopy (DBE) in the First Affiliated Hospital of Zhejiang University were retrospectively analyzed. Clinical, radiological and endoscopic data were collected. Univariate analysis was used to determine significant indicators for differentiating three main subtypes of PSIL. Cox regression analysis was performed to assess the risk factors for survival. RESULTS: In this study, 10 patients were pathologically diagnosed as diffuse large B-cell lymphoma (DLBCL), 11 were indolent B-cell lymphoma (BCL) and 9 were T-cell lymphoma (TCL). Compared with DLBCL patients, the body mass index (BMI) of TCL patients was significantly lower (p = 0.004). Meanwhile, compared with patients with DLBCL, the patients with indolent BCL had lower levels of C-reactive protein, lactate dehydrogenase (LDH), fibrinogen and D-Dimer (p = 0.004, p = 0.004, p = 0.006, and p = 0.002, respectively), and lower proportion of thicker intestinal wall and aneurysmal dilation in CT scan (p = 0.003 and p = 0.020, respectively). In terms of ulcer morphology, patients with DLBCL had significantly higher proportion of deep ulcers than patients with indolent BCL (p = 0.020, respectively). Cox regression analysis showed that drink (p = 0.034), concomitant colonic ulcers (p = 0.034) and elevated LDH (p = 0.043) are risk factors for mortality in patients with PSIL. CONCLUSIONS: This study provides clinical characteristics of patients with PSIL. Thicker intestinal wall and aneurismal dilation detected on CT scan and deeper ulcer on DBE examination helps to establish a diagnosis of DLBCL.

Examining the Impact of a GI Hospitalist Model on the Outcomes of Double-Balloon Enteroscopy: A Single-Center Retrospective Study.

BACKGROUND: A GI hospitalist (GIH) is a physician who practices in the inpatient setting performing consultations and endoscopic procedures. Obscure small bowel bleeding is a common inpatient diagnosis that is difficult to manage and associated with longer hospitalizations. Having an onsite GIH physician with expertise in video capsule endoscopy (VCE) and double-balloon enteroscopy (DBE) has the potential to improve patient outcomes. AIMS: This study will be the first to explore how implementing a GIH model and providing a GIH with training in DBE can affect the outcomes of patients with small bowel pathology. METHODS: We performed a retrospective study of patients who received an inpatient DBE at an academic medical center before and after initiation of a GIH model and credentialing of a GIH in DBE. We compared outcomes, including procedure volumes, diagnostic and therapeutic yields, procedure duration, time to procedure, and length of stay. RESULTS: There was a 46.5% increase in the number of DBEs performed by the GIH. The diagnostic yield increased from 56.3 to 74.0% (OR 2.2, 95% CI 1.2-4.2), and the proportion of DBEs with a therapeutic intervention increased from 38.0 to 65.4% (OR 3.1, 95% CI 1.4-7.0). The total procedure time increased from 77.8 to 96.4 min (p < 0.05) with a GIH. CONCLUSION: Having a GIH perform inpatient DBEs was associated with an increased number of procedures, duration of procedures, diagnostic yield, and therapeutic interventions. The onsite presence of a GIH with competency in DBE improves the care of hospitalized patients with small bowel pathology.

Preinduction cervical ripening in an outpatient setting: a prospective pilot study of a synthetic osmotic dilator compared with a double-balloon catheter.

OBJECTIVES: To compare the effectiveness, safety and patient satisfaction of a double balloon catheter (DB) with a synthetic osmotic cervical dilator (OD) for pre-induction cervical ripening in an outpatient setting. METHODS: This is a prospective, dual-center pilot study including 94 patients with an unripe cervix (Bishop Score <6) near term; 50 patients received the DB and 44 patients the OD. The primary outcomes were the difference in Bishop Score (BS) and cervical shortening. Pain perception at insertion and during the cervical ripening period was evaluated by a visual analogue scale and patient satisfaction by a predefined questionnaire. RESULTS: The use of DB was associated with a significantly higher increase in BS (median 3) compared to OD (median 2; p=0.002) and resulted in significantly greater cervical shortening (median -14 mm vs. -9 mm; p=0.003). There were no serious adverse events at placement of devices or during the cervical ripening. There were no significant differences in perinatal outcomes. Pain perception during cervical ripening was significantly higher (p<0.001), and patient satisfaction regarding sleep, relaxing time and performing desired daily activities were significantly lower in patients with DB compared to patients with OD (p<0.001). CONCLUSIONS: DB was superior to OD regarding cervical ripening based on BS and on sonographic measurement of the cervical length. Patients with OD experienced less pain during cervical ripening and were more satisfied with the method compared to patients with DB.

Efficacy and safety of double balloon catheter and dinoprostone for labor induction in multipara at term.

PURPOSE: The aim of this study was to comparatively assess the efficacy and safety of double balloon catheter (DBC) and dinoprostone as labor-inducing agents just for multipara at term. METHODS: A retrospective cohort study was conducted among multipara at term with a Bishop score < 6 who needed planned labor induction from January 1, 2020, to December 30, 2020 in Maternal and Child Health Hospital of Hubei province, Tongji Medical College, Huazhong University of Science and Technology. They were divided into DBC group and dinoprostone group, respectively. Baseline maternal data, maternal and neonatal outcomes were recorded for statistical analysis. Total vaginal delivery rate, rate of vaginal delivery within 24 h, rate of uterine hyperstimulation combined with abnormal fetal heart rate(FHR) were regarded as the primary outcome variables. The difference between groups was considered statistically significant when p value < 0.05. RESULTS: A total of 202 multiparas was included for analysis (95 women in DBC group vs 107 women in dinoprostone group). There were no significant differences in total vaginal delivery rate and rate of vaginal delivery within 24 h between groups. Uterine hyperstimulation combined with abnormal FHR occurred exclusively in dinoprostone group. CONCLUSION: DBC and dinoprostone seem to be equally effective, while, DBC seems to be safer than dinoprostone.

Factors affecting complete stone removal and bile duct stone recurrence in patients with surgically altered anatomy treated by double-balloon endoscopy-assisted endoscopic retrograde cholangiography.

OBJECTIVES: This study assessed factors influencing the complete removal and recurrence of bile duct stones in patients with surgically altered anatomy (SAA) undergoing double-balloon endoscopy-assisted endoscopic retrograde cholangiography (DBERC). METHODS: A retrospective analysis of 289 patients with SAA treated for biliary stones with DBERC at Jichi Medical University Hospital (January 2007 to December 2022) was conducted. Evaluation of factors impacting complete stone removal was performed in 257 patients with successful bile duct cannulation. Logistic and Cox proportional hazards regression models were used to compute the odds ratios (ORs) and hazard ratios (HRs) at 95% confidence intervals (CIs). RESULTS: Of 257 patients, 139 (54.0%) and 209 (81.3%) achieved initial and complete removal, respectively. Recurrence occurred in 55 (21.4%) patients. Factors associated with initial complete stone removal included cholangitis (P < 0.01, OR 0.48, 95% CI 0.27-0.83), number of stones (P < 0.01, OR 0.31, 95% CI 0.18-0.54), and largest stone diameter (P < 0.01, OR 0.37, 95% CI 0.20-0.67). The size of the largest stone was associated with complete removal (P = 0.01, OR 0.24, 95% CI 0.13-0.76). Recurrence was associated with cholangitis (P = 0.046, HR 0.54, 95% CI 0.29-0.99), congenital biliary dilatation (P = 0.01, HR 2.65, 95% CI 1.21-5.80), and number of stones (P = 0.02, HR 1.96, 95% CI 1.12-3.41). CONCLUSIONS: Successful complete bile stone removal in patients with SAA depends on the stone diameter and number. Stone recurrence is influenced by the number of stones and history of congenital biliary dilatation.

Crohn's disease with multiple jejunum and ileum lesions: A case report.

Crohn's disease (CD) affecting the jejunum and ileum is uncommon and its diagnosis can be challenging. This case report describes a 35 year old male patient who had been e xper iencing intermi ttent periu mbilica l pain , di arrho ea and fever for five years. Despite undergoing gastroscopy, co lo noscopy and capsule endoscopy; no s ignific ant abnormal ities were found. This case was se en at the Shenzhen Ho spital of Traditional Chinese Medi ci ne; Shenzhen, China. However, the pa tient u nder went a doubl e-balloon enteroscopy (DBE), which revealed multip le ulcers in the jejunum and ileum, leadin g to a confirmed diagnosis of CD. The patient was successfully treated with infliximab t o rel ieve sy mptoms. DBE can be par ticularly valuable in diagnosing CD in young patients with symptoms when conventional endoscopic techniques have been unsuccessfu l. This case highlights the impor tance of considering small bowel disease in patients wit h CD symptoms and the potential benefits of DBE in diagnosing such cases.

Evaluation of symptomatic small bowel stricture in Crohn's disease by double-balloon endoscopy.

PURPOSE: To assess the efficacy of double-balloon endoscopy (DBE) for the detection of small-bowel strictures in Crohn's disease (CD). METHODS: This tertiary-referral hospital cohort study was conducted between January 2018 and May 2022. CD patients with symptoms of small-bowel stricture were enrolled sequentially. All of the patients were subjected to both computed tomography enterography (CTE) and DBE, and their symptoms of stricture were assessed using the Crohn's Disease Obstructive Score (CDOS). The diagnostic yield of DBE was compared to that of CTE, and the relationship between the DBE findings and CDOS was investigated. The factors influencing the DBE diagnosis were examined using Cox regression analysis. RESULTS: This study included 165 CD patients. The CDOS scores were higher in 95 patients and lower in 70 patients. DBE detected 92.7% (153/165) and CTE detected 85.5% (141/165) of the strictures. The DBE diagnostic yields were 94.7% (90/95) in the high CDOS patients and 91.4% (64/70) in the low CDOS patients (P = 0.13). Patients with a history of abdominal surgery and abscess had a lower diagnosis rate in the multivariate analysis. CONCLUSION: DBE has been demonstrated to be an efficient diagnostic method for detecting small bowel strictures in CD patients. Additionally, there was no difference in the diagnostic yields between patients with low and high obstructive scores.

Endoscopic injection sclerotherapy for treating recurrent bleeding of small bowel angioectasias.

BACKGROUND: There is still no consensus on the preferred endoscopic therapy for small bowel angioectasias (SBAs). The aim of this study was to evaluate effectiveness and safety of endoscopic injection sclerotherapy (EIS) for treating recurrent bleeding of SBAs. METHODS: Sixty-six adult patients diagnosed with SBAs by capsule endoscopy (CE) or double-balloon enterscopy (DBE) examinations were enrolled in this retrospective study from September 2013 to September 2021. The patients were divided into an EIS group (35 cases) and a control group (31 cases) according to whether they underwent EIS treatment. Clinical characteristics, medical histories, lesion characteristics, main laboratory indicators, treatments, and outcomes were collected. The rates of re-bleeding, re-admission, and red blood cell (RBC) transfusion were compared between different groups after discharge. The rates of hospitalization and RBC transfusion were compared between before admission and after discharge in both groups. Odds ratios (ORs) and 95% confidence intervals (CIs) were used in the multivariate logistic regression analysis to assess relative factors for re-bleeding. RESULTS: All the rates of re-bleeding, re-admission and RBC transfusion after discharge in the EIS group were significantly lower than those in the control group (all P < 0.05). The rates of hospitalization and RBC transfusion after discharge were significantly lower than those before admission in the EIS group (both P < 0.05), while those did not reach significant differences in the control group (both P > 0.05). Multivariate logistic regression analysis showed that RBC transfusion before admission (OR, 5.655; 95% CI, 1.007-31.758, P = 0.049) and multiple lesions (≥ 3) (OR, 17.672; 95% CI, 2.246-139.060, P = 0.006) were significant risk factors of re-bleeding, while EIS treatment (OR, 0.037; 95% CI, 0.005-0.260, P < 0.001) was a significant protective factor. No endoscopic adverse events were observed during hospitalization and none of the enrolled patients died within 12 months after discharge. CONCLUSION: EIS treatment had good effectiveness and safety for treating recurrent bleeding of SBAs, which could be considered as one of the first-line endoscopic treatment options for SBAs.

Performance of Balloon-Assisted Enteroscopy for Non-ERCP Indications in Patients with Surgically Altered Gastrointestinal Anatomy.

BACKGROUND AND AIMS: Surgically altered gastrointestinal (GI) tract anatomy hinders deep enteroscopy. While enteroscopy-assisted endoscopic retrograde cholangiopancreatography (ERCP) in patients with altered GI anatomy has been heavily investigated, the role of non-ERCP balloon-assisted enteroscopy (BAE) has yet to be fully elucidated.Please check and confirm the author names and initials are correct. Also, kindly confirm the details in the metadata are correct.I have checked all you asked and have no correction.  Thank you. METHODS: A multicenter retrospective study of non-ERCP BAEs in patients with surgically altered GI tract anatomy at two tertiary academic hospitals was performed from January 2006 to December 2020. Altered GI tract anatomy was defined by surgical reconstruction affecting the length, angle, or overall trajectory of the endoscope during the intended approach. The main outcome measurements included technical success rate, diagnostic and therapeutic yields, and complication rate.Please check the edit made in the title of the article and correct if necessary.No more correction. Thank you. RESULTS: A total of 68 patients with surgically altered GI tract anatomy underwent 56 antegrade and 24 retrograde non-ERCP BAE procedures. The technical success rate was 86.2% in both, including 83.9% via antegrade approach and 91.7% via retrograde approach. Antegrade approach in Roux-en-Y anatomy was associated with the lowest success rate of 77.8%, whereas retrograde approach in patients with colon resection resulted in the highest rate of 100%. The diagnostic and therapeutic yields of non-ERCP BAE were 79.4% and 82.9%, respectively. The diagnostic yields varied according to the procedural indications. The major complication was luminal perforation in one case (1.3%). CONCLUSIONS: Non-ERCP BAE is effective and safe via both antegrade and retrograde approaches with a high technical success rate and diagnostic and therapeutic yields in patients with surgically altered GI tract anatomy.

Usefulness of Intestinal Ultrasound to Detect Small Intestinal Stenosis in Patients With Crohn's Disease.

OBJECTIVES: Double balloon enteroscopy (DBE) with retrograde contrast is useful as a monitoring tool for small intestinal lesions in Crohn's disease (CD), but these are burdensome for patients. Intestinal ultrasound (IUS) can be used with ease in daily clinical practice, but there is less evidence regarding the accuracy of detection of small intestinal stenosis in CD. This study aimed to examine the diagnostic power of IUS for small intestinal stenosis in patients with CD. METHODS: The findings of DBE and IUS in 86 patients with CD with small intestinal lesions were evaluated. Using DBE as the reference standard, we examined the detection rate of IUS for small intestinal stenosis. We evaluated three parameters: luminal narrowing, prestenotic dilation, and to-and-fro movement for determining stenosis using IUS. In addition, we compared the characteristics between the stenosis-detectable and stenosis-undetectable groups by IUS. RESULTS: Of the 86 patients, 30 had small intestinal stenosis. In IUS findings, when lesions that met two or more of the three parameters were judged as stenosis, the detection rate was 70.0% for sensitivity, 98.2% for specificity, and 88.4% for accuracy. Moreover, there were patients with a younger age at diagnosis (P < 0.05) and more ileocolonic disease location (P < 0.05) in the stenosis-detectable group by IUS. The stenoses detected by IUS were significantly longer than those undetected by IUS (14.1 mm versus 5.2 mm, P < 0.05). CONCLUSIONS: IUS delivered reliable results for clinically important small intestinal stenosis of CD with high diagnostic accuracy.

Simultaneous Double Balloon Dilatation for Supravalvar Pulmonary Obstruction After Arterial Switch Operation.

The optimal approach for supravalvar right ventricular outflow tract obstruction(RVOTO) after arterial switch operation(ASO) is unclear. The results of percutaneous balloon dilatation have been variable. We report the results of simultaneous double balloon dilation for RVOTO after ASO. Sixteen patients (1.3(0.7-3.8) years; 9.8(8.1-15.1) kgs underwent the procedure at 14(8-44.5) months after ASO. Salient technical features included placement of balloons over stiff guide-wires positioned in both branch pulmonary arteries to enable dilation of the distal-most main pulmonary artery (MPA) with high inflation pressures (~ 12-14 atmospheres) and short inflation-deflation cycles. Effective balloon size was based on the PA annulus or MPA distal to the narrowing. The final balloon: narrowest segment diameter ratio was 2.7. Following dilation, the right ventricle to systemic systolic pressure ratio decreased from 0.9 ± 0.18 to 0.52 ± 0.16 (p < 0.001) and mean RVOT gradient from 78 ± 18 to 34 ± 13.9 mmHg (p < 0.001). Narrowest diameter improved from 5.4 ± 2.2 to 9.2 ± 2.2 mm. There were no major complications. Two patients with inadequate relief (final RV-systemic ratios: 1.03 and 0.7) were referred for surgery. At median follow up of 9 months, IQR 7-22, range 5-73, others are free of re interventions with median RVOT gradient of 42, IQR 27-49, range 21-55 mmHg. The immediate and short-term follow up results of double balloon dilatation for supravalvar RVOTO is encouraging and may avoid the need for repeat surgery in the majority of patients. Further follow up is needed to determine the long-term durability of the results.

Small bowel endoscopy for children: Collaboration of capsule endoscopy and device-assisted enteroscopy.

Capsule endoscopy (CE) and balloon-assisted enteroscopy (BAE) have become indispensable techniques for the diagnosis and management of small bowel disease in both adult and pediatric cases. However, relevant differences exist in the indications between these cohorts, with body weight and age having particular relevance in decisions for the latter. Both CE and BAE are designed for adult physique and they were not widely used among children. In addition, the types of small intestinal diseases differ between adults and children, and consequently, the indications also differ between them. This review focuses on the issues relevant to pediatric cases and describes the practical application of endoscopy in clinical practice. In conclusion, although there are age and weight restrictions, both CE and BAE are safe and useful devices for use in children, and their indications for use in children are likely to expand in the future.

Double-balloon catheter vs dinoprostone (PGE-2) insert for labour induction: A meta-analysis of 2493 pregnancies.

Induction of labor (IOL) is the stimulation of the uterus during pregnancy to begin the onset of labour. Nearly two of five pregnancies require IOL. We compared the effectiveness of double-balloon catheter (DBC) with dinoprostone (PGE-2) insert for labour induction from previous studies. We included randomized controlled trials (RCTs) that compared the safety and efficacy of DBC to PGE-2. To evaluate the studies, we utilized the Cochrane tool for risk of bias assessment. The rates of vaginal birth and cesarean section were the primary outcomes. We included ten RCTs in this meta-analysis with a total sample of 2493 singleton pregnancies. After 24 hours, there was no significant difference in the delivery rates between DBC and PGE-2 s [R.R=1.08, 95% CI, (0.77, 1.52), P.value=0.65], and the rate of cesarean delivery [R.R=1.03, 95% CI, (0.90; 1.18), P.value=0.65]. The DBC showed a significantly higher oxytocin use rate compared to the PGE-2 group [R.R=1.77, 95% CI, (1.41; 2.32), P.value<0.0001]. In the PGE-2 group, there was a significantly higher risk of uterine hyperstimulation, tachysystole, and umbilical artery PH levels below 7. There was no significant difference in the efficacy between the PGE-2 and DBC in terms of delivery rate in 24 hours and the rate of cesarean delivery except for a slight BISHOP score improvement with DBC. However, DBC showed a higher rate of oxytocin use compared to the PGE-2, the DBC seems to be safer with a lower risk of umbilical artery PH < 7, uterine hyperstimulation, and tachysystole incidence than PGE-2.

Enterolith Treated with a Combination of Double-Balloon Endoscopy and Cola Dissolution Therapy.

A 71-year-old woman with rheumatoid arthritis who had been taking NSAIDs for many years consulted our hospital for abdominal pain. She was diagnosed with a small bowel obstruction due to an enterolith according to an abdominal CT scan that showed dilation from the enterolith in the small intestine on the oral side. It was considered that the intestinal stone was formed due to stagnation of intestinal contents and had gradually increased in size, resulting in an intestinal obstruction. We performed antegrade double-balloon endoscopy (DBE) to observe and remove the enterolith. We used forceps and a snare to fracture the enterolith. During this attempt, we found a seed in the center of the enterolith. Since the intestinal stone was very hard, cola dissolution therapy was administered from an ileus tube for 1 week. The following week, DBE was performed again, and it was found that the stone had further softened, making attempts at fracture easier. Finally, the enterolith was almost completely fractured. Intestinal stenosis, probably due to ulcers caused by NSAIDs, was found. Small bowel obstruction with an enterolith is rare. In this case, it was considered that the seed could not pass through the stenotic region of the small intestine and the intestinal contents had gradually built up around it. It has been suggested that DBE may be a therapeutic option in cases of an enterolith. Further, cola dissolution therapy has been shown to be useful in treating an enterolith, with the possible explanation that cola undergoes an acid-base reaction with the enterolith. In summary, we report, for the first time, treatment of an enterolith with a combination of DBE and cola dissolution therapy, thereby avoiding surgery and its risks.

Diagnostic yield of inpatient capsule endoscopy.

BACKGROUND: Capsule endoscopy (CE) provides a novel approach to evaluate obscure gastrointestinal bleeding. Yet CE is not routinely utilized in the inpatient setting for a variety of reasons. We sought to identify factors that predict complete CE and diagnostically meaningful CE, as well as assess the impact of inpatient CE on further hospital management.1 na d2 METHODS: We conducted a retrospective review of patients undergoing inpatient CE at a tertiary referral, academic center over a 3 year period. We analyzed data on patient demographics, medical history, endoscopic procedures, hospital course, and results of CE. The primary outcome was complete CE and the secondary outcome was positive findings of pathology on CE. RESULTS: 131 patients were included (56.5% were men 43.5% women, median age of 71.0 years). Overall, CE was complete in 77.1% of patients. Complete CE was not related to motility risk factors, gender, or administration modality. Patients with incomplete CE tended to be older, have lower BMI, and Caucasian, however results did not reach statistical significance (p = 0.06; p = 0.06; p = 0.08 respectively). Positive CE was noted in 73.3% of patients, with 35.1% of all patients having active bleeding. Positive CE was not associated with AVM risk factors or medication use. 28.0% of patients underwent subsequent hospital procedures, among which 67.6% identified the same pathology seen on CE. CONCLUSIONS: Contrary to previous studies, we found the majority of inpatient CEs were complete and positive for pathology. We found high rates of correlation between CE and subsequent procedures. The use of CE in the inpatient setting helps to guide the diagnosis and treatment of hospitalized patients with obscure gastrointestinal bleeding.

Hepatolithiasis After Living Donor Liver Transplantation in Pediatric Patients: Mechanism, Diagnosis, Treatment, and Prognosis.

There is little information about the outcomes of pediatric patients with hepatolithiasis after living donor liver transplantation (LDLT). We retrospectively reviewed hepatolithiasis after pediatric LDLT. Between May 2001 and December 2020, 310 pediatric patients underwent LDLT with hepaticojejunostomy. Treatment for 57 patients (18%) with post-transplant biliary strictures included interventions through double-balloon enteroscopy (DBE) in 100 times, percutaneous transhepatic biliary drainage (PTBD) in 43, surgical re-anastomosis in 4, and repeat liver transplantation in 3. The median age and interval at treatment were 12.3 years old and 2.4 years after LDLT, respectively. At the time of treatments, 23 patients (7%) had developed hepatolithiasis of whom 12 (52%) were diagnosed by computed tomography before treatment. Treatment for hepatolithiasis included intervention through DBE performed 34 times and PTBD 6, including lithotripsy by catheter 23 times, removal of plastic stent in 8, natural exclusion after balloon dilatation in 7, and impossibility of removal in 2. The incidence of recurrent hepatolithiasis was 30%. The 15-years graft survival rates in patients with and without hepatolithiasis were 91% and 89%, respectively (p = 0.860). Although hepatolithiasis after pediatric LDLT can be treated using interventions through DBE or PTBD and its long-term prognosis is good, the recurrence rate is somewhat high.

Fecal calprotectin predicts endoscopic activity and mucosal healing of small bowel Crohn's disease evaluated by double-balloon endoscopy.

PURPOSE: Fecal calprotectin (FC) levels can reflect the level of intestinal inflammation. Crohn's disease (CD), which affects the small bowel, has not been linked to FC levels. We determined if FC levels and endoscopic activity were related by performing double-balloon endoscopy (DBE). METHODS: Herein, patients with small bowel CD diagnosed by DBE between January 2020 and January 2022 were prospectively observed. Feces and blood samples of patients were collected before performing DBE and checked for the levels of FC and serological biomarkers. The endoscopic activity and mucosal healing (MH) were evaluated using the partial simple endoscopic score (pSES-CD). RESULTS: In all 254 CD patients, FC levels were correlated with pSES-CD (r = 0.775, P < 0.001). Even in patients with isolated small bowel CD, FC levels were strongly correlated with pSES-CD (r = 0.753, P < 0.001). In all patients, FC as an endoscopic remission indicator was found to have an area under the curve (AUC) of 0.872, with a cut-off value of 156.09 µg/g. In patients with isolated small bowel CD, FC yielded a high AUC of 0.865 for predicting endoscopic remission, with a cut-off value of 211.48 µg/g, sensitivity of 73.95%, and specificity of 91.30%. FC was optimally cut-off at 76.99 µg/g to predict MH in accordance with the AUC of 0.877. CONCLUSIONS: Using DBE findings, FC was found to be significantly correlated with pSES-CD. Even in isolated small bowel CD, FC may be a more reliable marker of accurately predicting endoscopic remission and MH.
