Replacing plastic bread clips with cardboard will prevent bowel perforation.

Plastic bread clips cause significant morbidity and mortality if accidentally ingested. A review of all existing case reports published in medical literature was conducted in PubMed, MedLine and Google Scholar. Key words included but was not limited to; clip, tag, tab, closure, kwik lok, bread, bag, ingestion, bowel, obstruction, perforation, plastic and foreign body. References of all the articles were sought out to ensure completeness. Fifty-six cases between 1975 and 2020 were analysed to understand the complications and the characteristics of the bread clip that caused these. About 28% of case reports described bowel perforation, with 61% of these occurring in the small bowel. Plastic bread clips are firm in nature, long lasting, and are shaped to grasp onto bowel, thus leading to these complications. Commercially available alternatives are introduced in order to encourage replacing plastic bread clips worldwide.

Association of Co-Exposure of Antenatal Steroid and Prophylactic Indomethacin with Spontaneous Intestinal Perforation.

OBJECTIVE: To evaluate the association of a combined exposure to antenatal steroids and prophylactic indomethacin with the outcome of spontaneous intestinal perforation (SIP) among neonates born at <26 weeks of gestation or <750 g birth weight. STUDY DESIGN: We conducted a retrospective study of preterm infants admitted to Canadian Neonatal Network units between 2010 and 2018. Infants were classified into 2 groups based on receipt of antenatal steroids; the latter subgrouped as recent (≤7 days before birth) or latent (>7 days before birth) exposures. The co-exposure was prophylactic indomethacin. The primary outcome was SIP. Multivariable logistic regression analysis was used to calculate aORs. RESULTS: Among 4720 eligible infants, 4121 (87%) received antenatal steroids and 1045 (22.1%) received prophylactic indomethacin. Among infants exposed to antenatal steroids, those who received prophylactic indomethacin had higher odds of SIP (aOR 1.61, 95% CI 1.14-2.28) compared with no prophylactic indomethacin. Subgroup analyses revealed recent antenatal steroids exposure with prophylactic indomethacin had higher odds of SIP (aOR 1.67, 95% CI 1.15-2.43), but latent antenatal steroids exposure with prophylactic indomethacin did not (aOR 1.24, 95% CI 0.48-3.21), compared with the respective groups with no prophylactic indomethacin. Among those not exposed to antenatal steroids, mortality was lower among those who received prophylactic indomethacin (aOR 0.45, 95% CI 0.28-0.73) compared with no prophylactic indomethacin. CONCLUSIONS: In preterm neonates of <26 weeks of gestation or birth weight <750 g, co-exposure of antenatal steroids and prophylactic indomethacin was associated with SIP, especially if antenatal steroids was received within 7 days before birth. Among those unexposed to antenatal steroids, prophylactic indomethacin was associated with lower odds of mortality.

Gestational Age-Dependent Variations in Effects of Prophylactic Indomethacin on Brain Injury and Intestinal Injury.

OBJECTIVE: To evaluate the impact of prophylactic indomethacin on early death (<10 days after birth) or severe neurologic injury and on early death or spontaneous intestinal perforation by completed weeks of gestational age in neonates born <29 weeks of gestation. STUDY DESIGN: This was a multicenter, retrospective cohort study of neonates (n = 12 515) born at 236/7 weeks of gestational age, admitted to neonatal intensive care units participating in the Canadian Neonatal Network who received prophylactic indomethacin started within the first 12 hours after birth. Univariate and multivariate analysis compared the composite outcomes of early death or severe neurologic injury and early death or spontaneous intestinal perforation. RESULTS: Of 12 515 eligible neonates, 1435 (11.5%) were exposed to prophylactic indomethacin; recipients were of lower gestational age and birth weight and had greater severity of illness (Score of Neonatal Acute Physiology with Perinatal Extension) on admission compared with nonrecipients. After we adjusted for confounders, prophylactic indomethacin was associated with reduced odds of early death or severe neurologic injury and early death or spontaneous intestinal perforation in neonates born at 23-24 weeks of gestational age. However, prophylactic indomethacin was associated with increased odds of early mortality or spontaneous intestinal perforation for neonates born at 26-28 weeks of gestational age. CONCLUSIONS: Prophylactic indomethacin use was associated with benefit in neonates born at 23-24 weeks of gestational age, but with harm at 26-28 weeks of gestational age. Given the observation of significantly improved survival, a randomized controlled trial is needed to investigate the effect of prophylactic indomethacin in babies born at 23-25 weeks of gestational age.

Prophylactic efficacy of enteral antifungal administration of miconazole for intestinal perforation, especially for necrotizing enterocolitis: a historical cohort study at a single institution.

PURPOSE: Despite improvements in neonatal intensive care, the outcomes of extremely-low-birth-weight infants (ELBWIs) with surgical diseases remain to be improved. We started administering enteral miconazole (MCZ) to ELBWIs from 2002 to prevent fungal infection. Since then, the incidence of intestinal perforation has significantly decreased. We investigated this prophylactic effect of MCZ against necrotizing enterocolitis (NEC) and focal intestinal perforation (FIP) and explored a new prophylactic concept against intestinal perforation. METHODS: We designed a historical cohort study to evaluate the effect of MCZ for intestinal perforation in ELBWIs who underwent treatment in our neonatal intensive-care unit between January 1998 and December 2005. We divided these cases into two groups: the Pre-MCZ group and the Post-MCZ group. We compared the morbidity, clinical outcomes and pathological features of NEC and FIP. RESULTS: The rate of intestinal perforation with NEC was significantly reduced after the introduction of MCZ (p = 0.007, odds ratio; 3.782, 95% confidence interval; 1.368-12.08). The pathological findings of NEC specimens showed that the accumulation of inflammatory cells was significantly reduced in the Post-MCZ group when compared with the Pre-MCZ group (p < 0.05). CONCLUSIONS: The efficacy of the enteral administration of MCZ on intestinal perforation with NEC highlights a new prophylactic concept in the clinical management of ELBWIs.

The Efficacy of Autologous Myoblast Sheet Transplantation to Prevent Perforation After Duodenal Endoscopic Submucosal Dissection in Porcine Model.

The recent advent of endoscopy has enabled the endoscopic submucosal dissection (ESD) of superficial nonampullary duodenal epithelial tumors. However, the substantially thin wall and presence of bile and pancreatic juice make it technically difficult to perform duodenal ESD without perforation, which leads to lethal complications. The present study evaluated the efficacy of autologous myoblast sheet transplantation for the prevention of late perforation after duodenal ESD in a porcine model. Two weeks before ESD, skeletal muscle was surgically excised from the femur of pigs, and myoblasts were isolated and seeded in temperature-responsive culture dishes to prepare sheets. Immediately after ESD, the autologous myoblast sheets were attached to the serosal surface at the ESD site with omentopexy. The pigs were divided into two groups: the autologous myoblast sheet group (n = 5), where the myoblast cell sheet was attached to the ESD ulcer part from the duodenal serous side, and the Omentum group (n = 5), where only the omentum was used. The pigs were sacrificed and analyzed macroscopically and histologically on postoperative day 3. The macroscopic examination of the abdominal cavity revealed perforation in the ESD ulcer area and leakage of bile in the Omentum group but no perforation in the Sheet group. A histopathological examination revealed that continuity of the duodenal wall at the ESD site was maintained with dense connective tissue in the Sheet group. In conclusion, autologous myoblast sheets were useful for preventing perforation after duodenal ESD.

Effect of prophylactic closure on adverse events after colorectal endoscopic submucosal dissection: A meta-analysis.

BACKGROUND AND AIM: Endoscopic submucosal dissection (ESD) has a high en bloc resection rate and is widely performed for large colorectal lesions. However, colorectal ESD is associated with a high frequency of adverse events (AEs), and the efficacy of prophylactic endoscopic closure after ESD for preventing AEs is still controversial. This meta-analysis was conducted to assess the efficacy of closure on AEs following colorectal ESD. METHODS: We searched PubMed, Embase, and the Cochrane Library for eligible studies. The chi-square-based Q statistics and the I2 test were used to test for heterogeneity. Pooling was conducted using a fixed or random effects model. RESULTS: We identified eight eligible studies that compared the effects of closure vs non-closure with respect to delayed bleeding, delayed perforation, and post-ESD coagulation syndrome. Compared with non-closure (5.2%), closure was associated with a lower incidence (0.9%) of delayed bleeding (pooled odd ratios [ORs]:0.19, 95% CI: 0.08-0.49) following ESD. The pooled ORs showed no significant differences in incidence of delayed perforation (pooled OR: 0.22; 95% CI: 0.05-1.03) or post-ESD coagulation syndrome (pooled OR:0.75; 95% CI: 0.26-2.18) between the closure and non-closure groups. CONCLUSION: Prophylactic endoscopic closure may reduce the incidence of delayed bleeding following ESD of colorectal lesions. Future studies are needed to further illuminate risk factors and stratify high risk subjects for a cost-effective preventive strategy.

Role of Nutrition in Prevention of Neonatal Spontaneous Intestinal Perforation and Its Complications: A Systematic Review.

BACKGROUND: Spontaneous intestinal perforation (SIP) is a devastating complication of prematurity, and extremely low birthweight (ELBW < 1000 g) infants born prior to 28 weeks are at highest risk. The role of nutrition and feeding practices in prevention and complications of SIP is unclear. The purpose of this review is to compile evidence to support early nutrition initiation in infants at risk for and after surgery for SIP. Methods: A search of PubMed, EMBASE and Medline was performed using relevant search terms according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Abstracts and full texts were reviewed by co-first authors. Studies with infants diagnosed with SIP that included information on nutrition/feeding practices prior to SIP and post-operatively were included. Primary outcome was time to first feed. Secondary outcomes were incidence of SIP, time to full enteral feeds, duration of parenteral nutrition, length of stay, neurodevelopmental outcomes and mortality. Results: Nineteen articles met inclusion criteria-nine studies included feeding/nutrition data prior to SIP and ten studies included data on post-operative nutrition. Two case series, one cohort study and sixteen historical control studies were included. Three studies showed reduced incidence of SIP with initiation of enteral nutrition in the first three days of life. Two studies showed reduced mortality and neurodevelopmental impairment in infants with early feeding. Conclusions: Available data suggest that early enteral nutrition in ELBW infants reduces incidence of SIP without increased mortality.

High-Tech Diagnostic Methods and Enteroscopic Treatment of Children with Peutz-Jeghers Syndrome.

INTRODUCTION: Peutz-Jeghers syndrome (PJS) is an autosomal dominant hereditary hamartomatous polyposis with predominant localization in the jejunum and ileum and high risk of bowel perforation after traditional polypectomy. The modern enteroscopy is the only possible technique for visualizing and performing intraluminal endoscopic microsurgical manipulations in the deep sections of the small intestine. The study aims to develop an optimal method for the diagnosis and treatment of polyps in children with PJS. MATERIALS AND METHODS: During 2015 to 2018 we conducted 30 comprehensive examinations of children with PJS in The Department of Endoscopic Research of the National Medical Research Center for Children's Health. We performed esophagogastroduodenoscopy and colonoscopy with removal of polyps more than 7 mm, then video capsule endoscopy and, guided by this, therapeutic single-balloon enteroscopy. Our technique for removal of polyps is general in all parts: (1) creating a "resistant pillow"; (2) electroexcision of polyp; (3) clipping the removal site. RESULTS: Successfully performed electroexcision of polyps, which were located in the deep parts of the small intestine at a distance of 30 segments (one segment is 10 cm), reached a diameter of 2.5 cm, had a long pedicle. The postoperative period was uneventful. CONCLUSION: We have developed an optimal method of diagnostic and therapeutic measures, the observance of which allows us to avoid delayed perforations of the small intestine in the area of polypectomy in the postoperative period in children with PJS. Thanks to this technique, modern enteroscopy is becoming the only possible alternative to bowel resection in children with PJS.

Endoscopic Retrograde Cholangiopancreatography-Related Complications and Their Management Strategies: A "Scoping" Literature Review.

Endoscopic retrograde cholangiopancreatography (ERCP) is a well-known procedure with both diagnostic and therapeutic utilities in managing pancreaticobiliary conditions. With the advancements of endoscopic techniques, ERCP has become a relatively safe and effective procedure. However, as ERCP is increasingly being utilized for different advanced techniques, newer complications have been noticed. Post-ERCP complications are known, and mostly include pancreatitis, infection, hemorrhage, and perforation. The risks of these complications vary depending on several factors, such as patient selection, endoscopist's skills, and the difficulties involved during the procedure. This review discusses post-ERCP complications and management strategies with new and evolving concepts.

Do total parenteral nutrition and bowel rest reduce the risk for perforation in patients with gastrointestinal tract lymphoma receiving chemotherapy?

OBJECTIVES: Gastrointestinal tract (GIT) lymphoma is associated with a risk for perforation while the patient is receiving chemotherapy. The role of total parenteral nutrition (TPN) and bowel rest in preventing perforation is unknown. The aim of this study was to examine the clinical outcomes of TPN and bowel rest in patients with GIT lymphoma who were receiving chemotherapy. METHODS: We reviewed all patients with GIT biopsy-proven lymphoma in our institution between 2013 and 2017. Patients were stratified into two groups, with and without TPN and bowel rest during chemotherapy. We identified 158 patients with GIT lymphoma. Of these, 47 (29.7%) received TPN and bowel rest before chemotherapy. Patients who received TPN were younger, more likely to have aggressive lymphoma in the small or large bowel. The primary outcome was to compare the perforation rate between the two groups. Secondary outcome analysis included infection rate and survival. RESULTS: Patients with perforation had significantly poorer survival. Perforation rate was similar between the TPN and the non-TPN groups (8.5% versus 2.7%, P = 0.197). Overall survival was similar between the two groups (P = 0.659). The TPN group had a higher infection rate (odds ratio, 5.32; 95% confidence interval, 1.36-20.8) after adjustment for covariates (age, types of lymphoma, and location of lymphoma). CONCLUSION: The present study demonstrated that TPN and bowel rest did not reduce the risk for perforation among patients with GIT lymphoma who were receiving chemotherapy. As the practice of prophylactic TPN and bowel rest was associated with higher infection risk and longer hospitalization, we do not recommend such practice for all patients with GIT lymphoma receiving chemotherapy.

Delayed diagnosis of anorectal malformations in neonates.

BACKGROUND: Anorectal malformations (ARM) are common congenital abnormalities of the terminal hindgut. Ideally, ARM should be diagnosed at, or shortly following, birth by careful physical examination of the perineum. Delayed diagnosis has been implicated as a risk factor for complications, including intestinal perforation. This study aimed to determine the rate of delayed diagnosis and associated intestinal perforation in ARM. METHODS: A retrospective review was performed for all ARM patients managed at The Royal Children's Hospital over a 16-year period (2000-2015). Data collected included ARM type, timing of diagnosis and complications. Delayed diagnosis was defined as being at more than 24 h of age. RESULTS: A total of 243 ARM patients (male 146/243, 60%) were included. The most frequent ARM types were perineal fistula (83/243, 34%) and rectovestibular fistula (40/243, 16%). Diagnosis was delayed beyond 24 h of age in 92 of 243 (38%) patients. The ARM type most commonly delayed in diagnosis was perineal fistula (37/83, 45%). Two patients in whom diagnosis was delayed suffered an intestinal perforation. CONCLUSION: Delayed diagnosis in ARM patients remains a common, and potentially fatal, occurrence. Improved assessment of newborns is required to ensure timely diagnosis of ARM, and avoidance of complications associated with delayed diagnosis.

Alvarado Scores Predict Additive Value of Magnetic Resonance Imaging in Workup of Suspected Appendicitis in Children.

BACKGROUND: The presentation of appendicitis in pediatrics is variable, and diagnostic imaging is often used. Magnetic resonance imaging (MRI) is replacing computed tomography in some centers, particularly after a nondiagnostic ultrasound (NDUS). Nonetheless, MRI is not widely used in this setting because of cost, procedure time, institutional capacity, and high rates of negative scans. We hypothesized that the Alvarado Score (AS) could be used to determine the additive diagnostic value of MRI after an NDUS. MATERIALS AND METHODS: Retrospective review of patients aged ≤18 y at a single tertiary care children's hospital who received an ultrasound for suspected appendicitis during 10 consecutive months in 2017. NDUS were defined as nonvisualization of the appendix or secondary signs without radiologic diagnosis. AS were retrospectively calculated from the electronic medical record. Primary outcomes were pathology-confirmed appendicitis, appendectomy, and perforation. RESULTS: AS was determined for 352 patients out of 463 who met inclusion criteria (76%). Sixty-two percent had an NDUS, and 45% of these patients received MRI. Patients with high-risk AS were significantly more likely to have MRI diagnostic of appendicitis (P = 0.0015), and low-risk AS patients were more likely to have a negative or equivocal MRI (P = 0.0169). Twenty-one MRI scans were required per each additional diagnosis of appendicitis in patients with low AS after NDUS versus 4.2 in intermediate-risk AS patients and 2.1 in high-risk AS patients. CONCLUSIONS: Risk stratification with AS can help assess the additive diagnostic utility of MRI after NDUS. MRI may be overutilized for diagnosing acute appendicitis in pediatric patients with low-risk AS.

[Medical Dispute Related to Gastrointestinal Endoscopy Complications: Prevention and Management].

Because gastrointestinal (GI) endoscopy examinations are being performed increasingly frequently, the rate of detection of cancer and of precancerous lesions has increased. Moreover, development of more advanced endoscopic technologies has expanded the indications for, and thus frequency of, therapeutic endoscopic procedures. However, the incidence of complications associated with diagnostic or therapeutic GI endoscopy has also increased. The complications associated with GI endoscopy can be ameliorated by endoscopic or conservative treatment, but caution is needed as some of the more serious complications, such as perforation, can lead to death. In this chapter, we review the possible complications of GI endoscopy and discuss methods for their prevention and treatment.

The pocket-creation method facilitates colonic endoscopic submucosal dissection (with video).

BACKGROUND AND AIMS: Colonic endoscopic submucosal dissection (ESD) is more difficult than rectal ESD because of poor maneuverability of the endoscope due to physiologic flexion, peristalsis, and respiratory movements. The aim of this study was to assess the usefulness of the pocket-creation method (PCM) for colonic ESD compared with the conventional method (CM) regardless of lesion shape or location. METHODS: A total of 887 colorectal lesions were treated by ESD. Of 887 lesions, 271 rectal lesions, 72 lesions smaller than 20 mm in diameter, and 1 non-neoplastic lesion were excluded. This is a retrospective chart review of the remaining 543 colon lesions in 512 patients. We divided them into the PCM group (n = 280) and the CM group (n = 263). The primary outcome was the en bloc resection rate. Secondary outcomes were R0 resection (en bloc resection with negative margin), adverse events, dissection time (in minutes), and dissection speed (in mm2/min). RESULTS: The PCM group achieved a significantly higher en bloc resection rate (PCM, 100% [280/280], vs CM, 96% [253/263]; P < .001) and R0 resection rate (91% [255/280] vs 85% [224/263], respectively; P = .033) than the CM group. Dissection time was similar (69.5 ± 44.4 vs 78.7 ± 62.6 minutes, P = .676). Dissection speed was significantly faster with the PCM than with the CM (23.5 ± 11.6 vs 20.9 ± 13.6 mm2/min, P < .001). The incidence of adverse events was similar (perforation, 2% vs 4% [P = .152], and delayed bleeding, 2% vs 1% [P = .361]). CONCLUSIONS: Colonic ESD using the PCM significantly improves the rates of en bloc resection and R0 resection and facilitates rapid dissection.

Is Intussusception a Middle-of-the-Night Emergency?

OBJECTIVES: Intussusception is the most common abdominal emergency in pediatric patients aged 6 months to 3 years. There is often a delay in diagnosis, as the presentation can be confused for viral gastroenteritis. Given this scenario, we questioned the practice of performing emergency reductions in children during the night when minimal support staff are available. Pneumatic reduction is not a benign procedure, with the most significant risk being bowel perforation. We performed this analysis to determine whether it would be safe to delay reduction in these patients until normal working hours when more support staff are available. METHODS: We performed a retrospective review of intussusceptions occurring between January 2010 and May 2015 at 2 tertiary care institutions. The medical record for each patient was evaluated for age at presentation, sex, time of presentation to clinician or the emergency department, and time to reduction. The outcomes of attempted reduction were documented, as well as time to surgery and surgical findings in applicable cases. A Wilcoxon rank test was used to compare the median time with nonsurgical intervention among those who did not undergo surgery to the median time to nonsurgical intervention among those who ultimately underwent surgery for reduction. Multivariable logistic regression was used to test the association between surgical intervention and time to nonsurgical reduction, adjusting for the age of patients. RESULTS: The median time to nonsurgical intervention was higher among patients who ultimately underwent surgery than among those who did not require surgery (17.9 vs 7.0 hours; P < 0.0001). The time to nonsurgical intervention was positively associated with a higher probability of surgical intervention (P = 0.002). CONCLUSIONS: Intussusception should continue to be considered an emergency, with nonsurgical reduction attempted promptly as standard of care.

[A step-up approach for dealing with rectal foreign bodies]. / Stapsgewijze aanpak bij rectaal corpus alienum.

Patients visiting a hospital with retained rectal foreign bodies can no longer be considered rare and the incidence appears to increase. Currently, little is known about management of patients with retained foreign bodies and there are no medical protocols for situations like this. There is no limit to the type of objects inserted into the anal canal, exposing clinicians to diagnostic and therapeutic dilemmas. Standardised algorithms for patients with retained foreign bodies are needed to avoid serious complications such as perforation or peritonitis. In this article, we present a 59-year-old, 57-year-old and 29-year-old male who visited the emergency department with inserted rectal foreign bodies and we propose a stepwise approach for dealing with retained rectal foreign bodies.

Can ultrasound reliably identify complicated appendicitis in children?

BACKGROUND: The ability of ultrasound to identify specific features relevant to nonoperative management of pediatric appendicitis, such as the presence of complicated appendicitis (CA) or an appendicolith, is unknown. Our objective was to determine the reliability of ultrasound in identifying these features. METHODS: We performed a retrospective study of children who underwent appendectomy after an ultrasound at four children's hospitals. Imaging, operative, and pathology reports were reviewed. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of ultrasound for identifying CA based on pathology and intraoperative findings and an appendicolith based on pathology were calculated. CA was defined as a perforation of the appendix. Equivocal ultrasounds were considered as not indicating CA. RESULTS: Of 1027 patients, 77.5% had simple appendicitis, 16.2% had CA, 5.4% had no evidence of appendicitis, and 15.6% had an appendicolith. Sensitivity and specificity of ultrasound for detecting CA based on pathology were 42.2% and 90.4%; the PPV and NPV were 45.8% and 89.0%, respectively. Sensitivity and specificity of ultrasound for detecting CA based on intraoperative findings were 37.3% and 92.7%; the PPV and NPV were 63.4% and 81.4%, respectively. Sensitivity and specificity of ultrasound for detecting an appendicolith based on pathology were 58.1% and 78.3%; the PPV and NPV were 33.1% and 91.0%, respectively. Results were similar when equivocal ultrasound and negative appendectomies were excluded. CONCLUSIONS: The high specificity and NPV suggest that ultrasound is a reliable test to exclude CA and an appendicolith in patients being considered for nonoperative management of simple appendicitis.
