Anecdotal evidence from preliminary observations has noted multiple instances where osteoporosis is present in elderly patients before the clinical detection of bowel disease, even in the absence of overt gastrointestinal symptoms. However, any potential association between these conditions remains to be further investigated. This computed tomography (CT) study investigates whether patients with gastrointestinal (GI) perforation have lower bone mineral density (BMD) than age and sex matched controls. BMD was measured by drawing 3D regions of interest in the bone marrow of the L1-L3 vertebral bodies on CT scans of each of 37 GI perforations and matched controls. Spectrometric calibration of Hounsfield units to the mineral scale was performed with density measurements in the paravertebral muscles (erector spinae) and subcutaneous adipose tissue. The mean BMD of patients with GI perforation (135.9 ± 24.3 mg/ml) was significantly lower than that of controls (96.9 ± 27.5 mg/ml, p < 0.05). The calculated T-and Z-scores of bone mineral density were also significantly different between the two groups (p < 0.05 for each) and were - 2.9 (± 0.90) and - 0.8 (± 0.91) in patients with GI perforation and - 1.6 (± 0.83) and 0 (± 0.96) in the control group, respectively. The results imply that patients with gastrointestinal (GI) perforation have lower bone mineral density (BMD) than age-and sex-matched controls, posing the question whether the screening and aggressive management of osteoporosis is high-risk populations for gastrointestinal perforation can prevent gastrointestinal complications in targeted populations., (© 2024.

An 87-year-old man experiencing lower abdominal discomfort resulting from the ingestion of a fish bone underwent conservative management involving endoscopic extraction of the fish bone lodged in the sigmoid colon. Most patients with lower gastrointestinal tract perforations typically develop peritonitis or abscesses, necessitating surgical intervention. Notably, endoscopic management of lower gastrointestinal tract perforations is infrequently employed. Patients presenting with localized abdominal symptoms along with a stable overall health condition may benefit from conservative therapeutic approaches that utilize endoscopic methods. Notably, the transition from endoscopic procedures for foreign body removal to surgical intervention requires close collaboration with a surgeon and must be executed judiciously.

An 83-year-old man was admitted to the emergency room with abdominal pain and bloating. Abdominal computed tomography (CT) revealed a sigmoid colon obstruction caused by colonic carcinoma involving a short segment with circumferential luminal narrowing. The patient underwent endoscopy with colonic self-expanding metallic stent (SEMS) placement as a bridge to surgery. Six days after SEMS placement, the patient was prepared for esophagogastroduodenoscopy for screening. Although screening revealed no complications, 8 h later, the patient complained of sudden abdominal pain. Emergency abdominal CT revealed that the SEMS was about to burst out of the colon. An emergency operation with sigmoidectomy and colostomy was performed, and operative findings revealed a colonic perforation by the SEMS at the proximal side of the tumor. The patient was discharged from the hospital without major problems. This case is a very rare complication of colonic SEMS insertion. It is possible that increased intraluminal bowel movement and/or CO2 pressure during the esophagogastroduodenoscopy caused colonic perforation. Endoscopic placement of a SEMS is an effective alternative to surgical decompression for treating colon obstruction. To avoid unexpected and unnecessary perforations, tests that could increase the intraluminal pressure within the intestine after SEMS insertion should be avoided.

Background: The purpose of this study was to improve diagnostic and therapeutic standards by examining the clinical features, treatment, and prognosis of fetal meconium peritonitis (FMP), as well as the diagnostic efficacy of ultrasound for FMP., Methods: The clinical data of 41 infants and pregnant women diagnosed with meconium peritonitis (MP) and treated at the Fujian Maternal and Child Health Hospital from January 2013 to January 2020 were analyzed retrospectively. Clinical data, imaging data, complications, treatment strategies, pregnancy outcomes, neonatal prognoses, and follow-up outcomes were all analyzed., Results: The MP prenatal diagnosis rate was 56.1% (23/41), the neonatal surgery rate was 53.7% (22/41), and the survival rate was 85.4% (35/41). Intraperitoneal calcification (23 pregnant women, 56.1%), intestinal dilatation (13 pregnant women, 31.7%), peritoneal effusion (22 pregnant women, 53.7%), intraperitoneal pseudocyst (7 pregnant women, 17.1%), and polyhydramnios were diagnosed via prenatal ultrasound (18 pregnant women, 43.9%). Twenty-two pregnant women were assigned to the surgical treatment (operation) group, while 18 were assigned to the conservative treatment group. In the operation group, there were 9 cases of ileal atresia (40.9%), 7 cases of jejunal atresia (31.8%), 2 cases of atresia at the jejunum-ileum junction (9.1%), 2 cases of ileal perforation (9.1%), 1 case of ileal necrosis (4.5%), and 1 case of adhesive obstruction (4.5%). There was no statistically significant difference ( p  > .05) in the occurrence of various prenatal ultrasound findings by etiology., Conclusion: Multiple prenatal ultrasound markers have been identified for MP. To improve the efficacy of newborn treatment for FMP and reduce neonatal mortality, dynamic monitoring of ultrasound image alterations and strengthened integrated perinatal management are necessary.

Perforation is the rarest complication of duodenal diverticulum but also one of its most serious complications. Mortality rate was reported to up to 30%. Clinical diagnosis is usually vague and non-specific. High clinical suspicion is important as rapid deterioration is likely. Consensus regarding management is lacking and currently guided by a small series of case reviews. Surgical treatment is historically the standard therapeutic option. However, more current literature suggests improvement in patients with non-surgical management. In this paper, we discuss a case of a patient in her early 60s who had a perforated duodenal diverticulum that was treated conservatively. It highlights the importance of a good history and a CT scan to help with diagnosis. Close clinical observation is essential to detect disease progression. A step-up approach to clinical deterioration with either percutaneous drainage or surgical management should be considered if the patient does not respond to conservative treatment., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Late perforation of the ileum is a rare and potentially life-threatening complication following intestinal resection. We present a unique case of a woman in her 60s with a history of appendiceal carcinoid tumour, who underwent a right hemicolectomy. Positron emission tomography and surveillance CTs showed normal surgical changes and no recurrent malignancy. Three years postoperatively, she presented with severe abdominal pain. CT revealed a perforation along the ileal wall of the ileocolonic anastomosis. She underwent emergent resection and repeat ileocolonic anastomosis. We conclude that the patient had subclinical ischaemia of the anastomosis, which eventually progressed to perforation 3 years later. We discuss a literature review on late small intestinal anastomotic perforations and their associated risk factors. Our case and literature review emphasise the importance of considering delayed anastomotic leak in postoperative patients with a history of intestinal cancer, inflammatory bowel disease, Roux-en-Y enteroenterostomy or side-to-side anastomosis., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Objective: We analyzed the incidence and mortality rate of gastrointestinal (GI) tract perforation after radiofrequency ablation (RFA) for hepatic tumors and assess its risk factors., Methods: This retrospective cohort study included 4799 patients with malignant tumors who underwent RFA (n = 7206). Sixty-nine cases of thermal injury to the GI tract were identified via a search of the electronic medical record system using index terms and divided into two groups according to the thermal injury with (n = 8) or without (n = 61) GI tract perforation based on follow-up CT reports. The risk factors for GI tract perforation were identified via multivariable logistic regression analysis using clinical, technical, and follow-up CT findings., Results: The incidence of thermal injury to the GI tract and GI tract perforation was 0.96 % (69/7206) and 0.11 % (8/7206), respectively. The type of adjacent GI tract and history of diabetes mellitus differed significantly between the two groups (p < 0.05). The index tumor being located around the small intestine was the only significant risk factor for GI tract perforation after ablation (Odds ratio, 22.69; 95 % confidence interval, 2.59-198.34; p = 0.005 [reference standard, stomach]). All perforations were not identified on CT images immediately after RFA. The median time to detection was 20 days (range, 3-41 days). Two patients (25 %, 2/8) died due to perforation-related complications., Conclusion: GI tract perforation after RFA for hepatic tumors is rare; however, it is associated with high mortality. Thus, careful follow-up is required after RFA if the index tumor is located around the small intestine., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Introduction and Importance: Long-term mechanical complications after inferior vena cava (IVC) filter placement include embedded or tilted filters, erosion of the vena cava, filter thrombosis. In the setting of caval thrombosis, patients may subsequently develop venous hypertension and post-thrombotic syndrome (PTS). Here we present three unique cases of IVC filter complications and surgical management., Case Presentation: A 30-year-old female presented with acute abdominal pain, revealing a duodenal perforation caused by an IVC filter eroding into her duodenum. A 42-year-old female with an IVC filter in place for 20 years due to a prior pulmonary embolism underwent laser-assisted retrieval of the filter due to concerns of caval adherence. A 48-year-old male with a history of DVT, venous stasis ulcer, and an IVC filter presented for filter retrieval., Clinical Findings and Investigations: The surgical techniques described in this report include complicated IVC filter retrieval, performed in cases of filter complications including migration, fracture, duodenal perforation and IVC thrombosis resulting in PTS. One case, requiring open retrieval, is explained and the surgical technique is provided. There are images and videos of these procedures to enrich the learning experience., Intervention and Outcomes: The surgical techniques described in this report include complicated inferior vena cava filter retrieval, performed in cases of filter complications including migration, fracture, duodenal perforation and IVC thrombosis. One case, requiring open retrieval, is explained and the surgical technique is provided. There are images and videos of these procedures to enrich the learning experience., Relevance and Impact: Endovascular retrieval of long-term complicated IVC filters is challenging, but it can be a safely performed in many patients. However, open surgery may be necessary in selected patients., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Lung pleomorphic carcinoma is a rare and aggressive cancer that uncommonly metastasizes to the colon and only a few case reports have been published thus far. We present an exceptional case of colon metastasis from lung pleomorphic carcinoma in a 68-year-old man which was revealed by large bowel perforation, and we review the previous three published cases. Metastasis to the bowel from primary lung malignancy often lacks specific symptoms which result in delayed diagnosis. Bowel metastasis is a poor prognostic factor in patients with lung pleomorphic carcinoma, regardless of management strategy., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Spontaneous, iatrogenic or surgical perforation of the whole gastrointestinal wall can lead to serious complications, resulting in increased morbidity and mortality. Optimal patient management requires early clinical appraisal and prompt imaging evaluation. Both radiologists and referring clinicians should recognize the importance of choosing the ideal imaging modality and the usefulness of oral and rectal contrast medium. Surgeons and radiologists should be familiar with CT and fluoroscopy findings of the normal and pathologic anatomy after esophageal, stomach or colon surgery. Specifically, they should be able to differentiate innocuous from clinically-relevant, life-threatening postoperative complications to guide appropriate treatment. Advantages of esophagram, CT-esophagram, CT after rectal contrast enema and other imaging modalities are discussed., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this article., (Copyright © 2024.

Toothpick ingestion is an uncommon condition. It has been reported that an estimated incidence of 3.6 toothpick related injuries per 100,000 people per year. However, the incidence of toothpick-related gastrointestinal tract perforation is as high as 80%, with small bowel perforation accounting for 18% of cases. Common symptoms associated with toothpick ingestion include abdominal pain, fever, nausea, diarrhea, and constipation. However, it may lead to peritonitis, abscesses, and sepsis in severe cases. The diagnosis of toothpick ingestion is difficult. Only a minority (12%) of patients remember eating toothpicks and the sensitivity of computed tomography (CT) and endoscopy is 43% and 70%, respectively. When a toothpick penetrates the small intestine or is accompanied by other adverse events such as peritonitis, the vast majority of patients undergo surgery. Double-balloon enteroscopy (DBE) is not only an examination method for small intestinal diseases, but also an endoscopic treatment for the removal of sharp foreign bodies such as toothpicks. We report an elderly woman who was diagnosed as toothpick penetrated the jejunal wall and successfully retrieval under DBE. To our best knowledge, there is currently only one report of removing toothpick from the small intestine using DBE. We figured that DBE is a feasible, safe, and effective treatment when toothpicks penetrate the small intestinal wall without other adverse events based on our presentation.

An 8-year-old cat was presented for an acute history of anorexia, marked abdominal pain, and hyperthermia. Ultrasonography showed a cecal perforation with focal steatitis and adjacent free gas bubbles, consistent with focal peritonitis. Surgery confirmed the imaging findings. An enterectomy was performed with the removal of the cecum and ileocolic valve, and anastomosis between the ileum and colon was performed. Histology revealed transmural enteritis and chronic severe pyogranulomatous peritonitis with intralesional plant fragments., (© 2024 American College of Veterinary Radiology.)

Rationale: Barium peritonitis is an inflammatory response that occurs when barium accidentally enters the abdominal cavity during a barium test. In extreme circumstances, it has the potential to harm various organs and even result in death., Patient Concerns: A 3-month-old infant was diagnosed with multiple organ failure after severe barium peritonitis., Diagnosis: Multiple organ dysfunction is associated with barium peritonitis., Interventions: The infant underwent surgical intervention and received ventilator support, anti-infection therapy, myocardial nutrition, liver and kidney protection, rehydration, circulation stabilization, and other symptomatic supportive care., Outcomes: The patient experienced clinical death after treatment and resuscitation was unsuccessful., Lessons: Barium enema perforation complications are uncommon, but can lead to fatal injuries with a high mortality rate. This case highlights the importance of raising awareness among clinicians about the risks of gastroenterography in infants and children and actively preventing and avoiding similar serious complications. The mortality rate can be reduced by timely multidisciplinary consultation and joint management once a perforation occurs., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Background: Accidental ingestion of foreign bodies is a common problem in children. Fortunately, the gastrointestinal tract is quite resilient to foreign bodies. On the other hand, the ingestion of magnets can result in enormous morbidity. Because of their natural tendency to firmly adhere they can cause intestinal obstruction, pressure necrosis, fistula formation or perforation. With this case report, we aim to raise awareness of the risks that these magnets pose to children., Methods: We describe a case of intestinal perforation caused by the separate ingestion of multiple magnets from a children's toy (buckyballs, Neodymium spheres) by a two-year-old boy. A search in the Pubmed database showed some publications and varied management guidelines., Results: The boy was treated with an exploratory laparoscopy converted to a mini-laparotomy. We removed the four magnets through separate enterotomies. Postoperative recovery was uneventful. The boy was discharged on a postoperative day five and had no complications at three months follow-ups., Conclusion: Accidental ingestion of multiple magnets is rare but can create a life-threatening situation in children. If the magnets are still in the stomach, endoscopic retrieval is needed. If they are beyond the stomach, in asymptomatic cases close clinical and radiographic vigilance is mandatory. When symptomatic we advise urgent removal. If treated on time, the surgical outcome is good and fast recovery is expected.

Case: An 85-year-old woman with a history of bladder mesh sling placement sustained a pelvic fracture and extraperitoneal bladder rupture after a ground-level fall. The patient underwent cystorrhaphy and percutaneous anterior column screw placement. Free air was identified on abdominal computed tomography scan on postoperative day 5. Exploratory laparotomy revealed a sigmoid colon perforation and extensive bowel adhesions to the anterior pelvis., Conclusion: This is the first report describing bowel injury and associated bladder rupture in a pelvic fragility fracture related to a prior bladder mesh sling. This case highlights the importance of obtaining a thorough surgical history when treating pelvic injuries., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJSCC/C280)., (Copyright © 2024 by The Journal of Bone and Joint Surgery, Incorporated.)

A 47-year-old woman was referred to our hospital with recurring lower abdominal pain persisting for more than 2 weeks. Imaging modalities showed small bowel obstruction caused by a mass lesion in the terminal ileum. Despite undergoing fasting, rehydration, and decompression through an ileus tube, her symptoms persisted. Furthermore, the condition deteriorated on day 4, with the onset of her menstrual period. An emergency surgery was conducted on the 7th day after hospitalization. Surgical observations indicated severe stenosis around the ileocecal valve and ileal perforation approximately 40cm from the oral stricture. As a result, ileocecal resection was performed. Pathological examination revealed endometrial tissue infiltration through the mucosal lamina propria to the ileal subserosa. Thus, the patient was identified with intestinal endometriosis of the ileocecum. Endometriosis of the small bowel is an uncommon condition that eventually causes intractable bowel obstruction. Although preoperative diagnosis is considered challenging, intestinal endometriosis should be included in the differential diagnosis in cases of bowel obstruction in women of childbearing age.

Background/purpose: Encapsulating peritoneal sclerosis (EPS) is a rare and potential lethal complication of peritoneal dialysis characterized by bowel obstruction. Surgical enterolysis is the only curative therapy. Currently, there are no tools for predicting postsurgical prognosis. This study aimed to identify a computed tomography (CT) scoring system that could predict mortality after surgery in patients with severe EPS., Methods: This retrospective study enrolled patients with severe EPS who underwent surgical enterolysis in a tertiary referral medical center. The association of CT score with surgical outcomes including mortality, blood loss, and bowel perforation was analyzed., Results: Thirty-four patients who underwent 37 procedures were recruited and divided into a survivor and non-survivor group. The survivor group had higher body mass indices (BMIs, 18.1 vs. 16.7 kg/m 2 , p = 0.035) and lower CT scores (11 vs. 17, p < 0.001) than the non-survivor group. The receiver operating characteristic curve revealed that a CT score of ≥15 could be considered a cutoff point to predict surgical mortality, with an area under the curve of 0.93, sensitivity of 88.9%, and specificity of 82.1%. Compared with the group with CT scores of <15, the group with CT scores of ≥15 had a lower BMI (19.7 vs. 16.2 kg/m 2 , p = 0.004), higher mortality (4.2% vs. 61.5%, p < 0.001), greater blood loss (50 vs. 400 mL, p = 0.007), and higher incidence of bowel perforation (12.5% vs. 61.5%, p = 0.006)., Conclusion: The CT scoring system could be useful in predicting surgical risk in patients with severe EPS receiving enterolysis., Competing Interests: Declaration of competing interest None Declared., (Copyright © 2023 Formosan Medical Association.

A 59-year-old woman presented with a chief complaint of melena. She had no abdominal findings, such as tenderness or tapping pain. Laboratory tests revealed a white blood cell count of 5,300 cells/μL and C-reactive protein level of 0.07 mg/dL. Inflammation and anemia (hemoglobin 12.4 g/dL) were denied. Contrast-enhanced computed tomography (CT) revealed multiple duodenal diverticula and air surrounding a descending duodenal diverticulum. Based on these findings, duodenal diverticular perforation (DDP) was suspected. Oral food intake was stopped, and nasogastric tube feeding and conservative treatment with cefmetazole, lansoprazole, and ulinastatin were begun. On day 8 of hospitalization, follow-up CT revealed the disappearance of the air surrounding the duodenum, and the patient was discharged on day 19 after the resumption of oral feeding.

We describe a case of a premature 24 weeks gestation infant who presented with clinical lability and abdominal distention with initial concerns of necrotising enterocolitis. On further examination, a right inguinal hernia was noted and serial abdominal X-rays showed bowel loop dilatation with intramural air and no perforation. However, the hernia was recurrent and later found to be not reducible. He underwent right groin exploration. Intraoperatively, distal ileal perforation was noted and he was found to have an additional five sites of perforation. He had a stoma sited at the left iliac fossa as well as primary anastomosis at the site of the second to fifth perforations. He had a stormy postoperative period but is currently doing well. Although obstructed hernias are rare in the initial course of an extreme preterm infant, it should not be missed as a cause of intestinal obstruction and early surgical opinion should be sought., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2023.

Background: Iatrogenic colon perforation (ICP) due to colonoscopy is a severe complication and is associated with significant morbidity and mortality. The global estimated incidence of ICP is 0.03% and up to 3% for diagnostic and therapeutic colonoscopies, respectively. Treatment options include endoscopic repair, conservative therapy, and surgery. Treatment decision is based on the time and the setting of the diagnosis, the type, and location of the perforation, the presence of related pathologies, the clinical status and characteristic of the patient, and surgeon's skills. We present our experience in the treatment of ICPs., Methods: A retrospective review was undertaken of all patients suffering from ICP at Bnai-Zion Medical Center between 1/1/2010 and 1/3/2021. Clinical presentation, therapeutic approach, and short-term outcomes were analyzed., Results: There were 51 cases of ICPs. Fourteen (27%) were diagnosed by the gastroenterologist during the procedure, 2 of whom were treated with endoscopic clips. The rest of the patients (72.5%) were diagnosed in the ER after a CT scan. Forty-three patients (84%) went on to operative management: 5 (11%) operations started with laparotomy-all were conducted in the early study period (until 2013). All other operations (88%) started with a diagnostic laparoscopy, 4 of whom (10%) were converted to laparotomy. Out of the 38 laparoscopic cases 29 (80%) were treated with primary suturing. Seven patients went on to colon resection (5 of whom with primary anastomosis). Six patients required ICU admission-with 1/38 (2%) from the laparoscopic cases, and 5/9 (55%) from the laparotomy cases. A total of 49/51 (96%) patients recovered and were discharged after 5 ± 2 for conservative and laparoscopic cases, and 12 ± 9 for open cases., Conclusion: Laparoscopic treatment of ICP is safe and feasible in most cases. Our data supports a laparoscopic attempt at any such scenario., (© 2023. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is essential for diagnosing and treating biliopancreatic disease. Because ERCP-related perforation can result in death, therapeutic decisions are important. The aim of this study was to determine the cause of ERCP-related perforation and suggest appropriate management., Methods: Between January 1999 and August 2022, 7,896 ERCPs were performed in our hospital. We experienced 15 cases (0.18%) of ERCP-related perforation and conducted a retrospective review., Results: Of the 15 patients, 6 were female and 9 were male, and the mean age was 77.1 years. According to Stapfer's classification, the 15 cases of ERCP-related perforation comprised 3 type I (duodenum), 3 type II (periampullary), 9 type III (distal bile duct or pancreatic duct), and no type IV cases. Fourteen of 15 (92.6%) were diagnosed during ERCP. The main cause of perforation was scope-induced damage, endoscopic sphincterotomy, and instrumentation penetration in type I, II, and III cases, respectively. Four patients with severe abdominal pain and extraluminal fluid collection underwent emergency surgery for repair and drainage. One type III patient with distal bile duct cancer underwent pancreaticoduodenectomy on day 6. Three type III patients with only retroperitoneal gas on computed tomography (CT) performed immediately after ERCP had no symptoms and needed no additional treatment. Seven of the 15 patents were treated by endoscopic nasobiliary drainage (n=5) or CT-guided drainage (n=2). There were no deaths, and all patients were discharged after treatment., Conclusions: Early diagnosis and appropriate treatment are important in managing ERCP-related perforation.

Small bowel obstructions are common surgical presentations that are most often caused by adhesions following abdominopelvic surgeries. However, in patients with no history of abdominal surgical interventions, assessment of the cause of a small bowel obstruction is more complex, and such patients frequently require operative intervention. We present a case of a 65-year-old man who presented with a small bowel obstruction caused by an inadvertent ingestion of a bread tag that was not identified on preoperative imaging. The sharp end of the bread tag had eroded through the small bowel leading to a walled-off perforation of the small bowel. Surgical resection was required.

This patient with Crohn's disease underwent endoscopic balloon dilatation of an ileocolic stricture, and shortly thereafter developed subcutaneous emphysema in the soft tissues of her face, neck, and chest wall. Clinical evaluation and imaging revealed peritonitis from perforated bowel. She underwent laparotomy and bowel resection and recovered well. Subcutaneous emphysema in the head and neck from perforated bowel is a rare but recognized presentation of viscus perforation.

Background: Presence of contrast agent in the urinary system in infants after small-bowel follow-through study with low-osmolar contrast media has been described as a sign of bowel perforation., Objective: To evaluate how often the presence of contrast agent in the bladder after small-bowel follow-through is a reliable sign of bowel perforation or necrosis., Materials and Methods: From the radiology information system, we retrieved imaging reports of infants evaluated with small-bowel follow-through and findings of contrast agent in the bladder. We retrieved demographic and clinical information from the medical records. Presence of bladder contrast medium was considered true-positive evidence of bowel perforation or necrosis if confirmed by pneumoperitoneum, extraluminal contrast agent, surgery or pathology within 3 days of the small-bowel follow-through. False-positives for bowel perforation or necrosis were based on surgical findings or clinical follow-up., Results: Of the 207 infants who had small-bowel follow-through, 18 infants (12 boys; mean age 50 days, range 14 days to 8.5 months) had contrast medium in the bladder after the small-bowel follow-through. Fifteen of the 18 (83.3%) had a history of prematurity and 11 had prior abdominal surgery. Four of the 18 (22.2%) had bowel perforation or necrosis at surgery or pathology performed more than 3 days after the small-bowel follow-through and were considered indeterminate and excluded. Eight of the remaining 14 infants (57.1%) had bowel perforation or necrosis based on surgical evidence of perforation or pathology confirmation of necrosis (n=6), pneumoperitoneum (n=1) or contrast agent leakage from enterocutaneous fistula (n=1). Six of the 14 (42.9%) were false-positives, without evidence of bowel perforation or necrosis based on clinical follow-up (n=4) or surgery (n=2)., Conclusion: Demonstration of urinary contrast agent post small-bowel follow-through with low-osmolar contrast medium in newborns/infants with complex medical problems is not a definitive indication of bowel perforation or necrosis. More than one-third of our patients with contrast medium in the bladder did not have bowel perforation or necrosis., (© 2022.

A 77-year-old man presented with abdominal pain for 1 week. He was taking enteric-coated low-dose aspirin (LDA) to prevent secondary cardiovascular events and a proton pump inhibitor (PPI). Computed tomography indicated a small intestinal perforation; thus, small intestine resection was performed. Two months after surgery, he experienced a recurrence of the perforation. Since his repeated perforation was suspected to be due to LDA, LDA was discontinued. He has experienced no further recurrence since then. This is the first case of small intestinal perforation caused by enteric-coated LDA. Enteric-coated LDA may cause small intestinal perforation in patients with severe atherosclerosis under PPI administration.

Ingestion of magnetic foreign bodies in pediatric settings has become more common in the last years due to the marketing of various toys containing small magnetic parts. Most magnets, especially if a single element is ingested, usually pass through the gastrointestinal tract without complications. However, ingestion of multiple magnets or magnets and small metallic components may require a prompt intervention due to the risk of attraction across bowel layers, leading to pressure necrosis, perforation, and even death. Routinely, serial radiological evaluations are needed to follow the progression of magnets through the intestine, while the role of small bowel ultrasound is regarded as marginal. Here we report a case of a 5-years old boy who ingested 8 magnets and in which small bowel ultrasound was pivotal for the correct assessment of magnets location to correct address the surgical approach., (© 2022.

Objective: To assess whether either duration and magnitude of ductal shunt or medical treatment for patent ductus arteriosus (PDA) are related to spontaneous intestinal perforation (SIP)., Study Design: Clinical charts of infants <29 weeks' gestation born from 2006 to 2018 were reviewed. Echocardiographic examinations were evaluated according to McNamara and Sehgal's staging system., Results: A higher percentage of patients with SIP had a hemodynamically significant PDA (HSPDA) and was treated with either NSAIDs or paracetamol (79% vs 53% and 81% vs 54%, respectively). Among non-treated patients, we found a 1.32 increase in the odds of SIP per day of persistence of HSPDA. In the cohort of patients treated despite the absence of HSPDA, we found a 2.35 increase in the odds of SIP per dose of drug administered., Conclusion: Both treating a non-HSPDA and leaving a HSPDA to its natural history seem to be associated with SIP., (© 2022.

The Necrotizing Enterocolitis Surgery Trial (NEST) highlights the importance of distinguishing necrotizing enterocolitis (NEC) from spontaneous intestinal perforation (SIP) when developing surgical treatment plans. Further research is needed to increase the accuracy of this distinction, but even with our current abilities to do this initial laparotomy appears to be optimal for infants with presumed NEC. The preferred initial operation for those with SIP is more equivocal. Rates of NEC are likely decreasing slowly, whereas those with SIP are not. New imaging modalities, especially ultrasound, are becoming more useful but require more detailed investigation. Understanding the mechanisms causing these two conditions remains of paramount importance., Competing Interests: Disclosure The authors have nothing to disclose., (Copyright © 2022 Elsevier Inc.

Colonoscopy is one of the most commonly performed endoscopic procedures and remains the most commonly used screening modality method for colorectal cancer (CRC) screening in the USA. Although serious complications of fiberoptic colonoscopy are uncommon due to technical advances, due to increasing number of colonoscopy procedures, post-procedural complications are not uncommonly encountered in the routine clinical practice. Also, as some of the post-colonoscopy complications are life threatening, it is important to diagnose them early so that timely treatment measures can be taken to decrease mortality and morbidity. In this review, we present a case-based illustration of the utility of CT to detect complications of colonoscopy including bowel perforation, hemorrhage, splenic injury, and postpolypectomy syndrome., (© 2022.
