[A case of small intestinal endometriosis with bowel obstruction and perforation].

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.

Immunoglobulin A Vasculitis With Intussusception in Children.

BACKGROUND: Immunoglobulin A (IgA) vasculitis with intussusception is acute and severe vasculitis combined with acute abdomen in children. The diagnosis of the disease depends on the results of imaging examinations, and its treatment mainly includes enema and surgery. The literature summarized the detailed diagnosis and treatment data in previous literature reports. METHODS: We described the clinical manifestations, ultrasonic features, and treatment of patients admitted to a single center and reviewed previous literature regarding cases with detailed clinical data in the PubMed database within the past 20 years. RESULTS: The review included 36 patients, including 22 boys and 14 girls. A total of 32 patients were diagnosed using ultrasound (88.9%). The main sites of intussusception were the ileum and ileocolon in 16 (44.4%) and 11 (30.6%) cases, respectively. Thirteen patients (36.1%) were treated with enema, with 6 responding to the treatment. 26 patients (72.2%) underwent surgical treatment. Patients with ileal intussusception were more likely to be treated with surgery than those with colonic intussusception (P < .05). The single-center clinical data of 23 patients showed that there was no significant difference in laboratory test findings between patients with and without surgical treatment (P > .05). Patients with long insertion lengths were more likely to require surgery and resection (P < .05). CONCLUSIONS: Ultrasonography is the first-line investigation for diagnosis. The main sites of intussusception were ileum and ileocolon. The length of intubation was related to surgery; treatment is according to the intussusception site. Air enema is not suitable for intussusception of the small intestine.

Disseminated Histoplasmosis Causing Temporally and Spatially Discrete Gastrointestinal Perforations in an HIV-Negative Patient.

Histoplasma capsulatum is a dimorphic fungi endemic to the Ohio and Mississippi River valleys. Immunocompetent persons who become infected are generally asymptomatic or present with mild symptoms. Symptomatic disease is seen primarily in immunocompromised patients with pulmonary manifestations being the most common presentation. We present a case of a young HIV-negative male who required 4 exploratory laparotomies over the course of 4 months during 2 hospitalizations due to discrete perforations of the ileum and jejunum caused by biopsy-proven gastrointestinal histoplasmosis despite maximal medical therapy as well as a gastric perforation.

Effects of sedatives on radiologic enema reduction in children with ileocolic intussusception: A systematic review and meta-analysis.

BACKGROUND: In children with ileocolic intussusception, sedatives such as midazolam, ketamine and propofol may facilitate radiologic enema reduction, but studies on their separate and joint effects remain controversial. OBJECTIVES: We aimed to systematically analyze studies for the effects of sedatives on the radiologic reduction of ileocolic intussusception in children. METHODS: We searched PubMed, EMBASE, CINAHL, Scopus and Web of Science from database inception through March 2023 for articles that enrolled children with ileocolic intussusception who underwent non-operative pneumatic or hydrostatic enema reduction under ultrasound or fluoroscopic guidance with or without the use of sedatives. The primary and secondary outcomes were success rate in radiologic reduction of ileocolic intussusception and risk of perforation, respectively. Effect estimates from the individual studies were extracted and combined using the Hartung-Knapp-Sidik-Jonkman log-odds random-effects model. Heterogeneity between studies was checked using Cochran's Q test and the I2 statistic. RESULTS: A total of 17 studies with 2094 participants were included in the final review, of which 15 were included in the meta-analysis. Nine studies reported on the success rate of radiologic reduction performed under sedation in all participants, while six studies compared the success rate in two patient groups undergoing the procedure with or without sedation. The pooled success rate of non-operative reduction under sedation was 87 % (95 % CI: 80-95 %), P = 0.000 with considerable heterogeneity (I2 = 85 %). A higher success rate of 94 % (95 % CI: 88-99 %) and homogeneity (I2 = 12 %) were found in studies with pneumatic enema reduction. Among comparative studies, the odds of success of non-operative reduction were increased when the procedure was performed under sedation, with a pooled odds ratio of 2.41 (95 % CI: 1.27-4.57), P = 0.010 and moderate heterogeneity (I2 = 60 %). In a sensitivity analysis, homogeneity was found between analyzed studies when two outliers were excluded (I2 = 0.73 %). The risk of perforation was not significantly different (OR 1.52, 95 % CI: 0.09-23.34), P = 0.764 indicating small study effects. No publication, bias was detected on visual inspection of the funnel plots or the Begg's and Egger's bias tests. Most studies were categorized as having a low risk of bias using Joanna Briggs Institute checklists. CONCLUSIONS: In selected patient groups, sedation can increase the success rate of radiologic enema reduction in children with ileocolic intussusception without evidence of increased risk of perforation.

Mantle cell lymphoma presenting as intussuscepting ascending colon mass.

Malignant lymphoma is a rare cause of gastrointestinal intussusception in adults, accounting for less than 1% of all cases of intussusception. This is a case of a South-East Asian woman in her 50s, presenting with intermittent abdominal pain, loose stools and weight loss. CT of the abdomen and pelvis showed an irregular mass causing ileocolic intussusception and she underwent emergency open right hemicolectomy with end ileostomy. Intraoperatively, her bowel was covered with lymphoma nodules, and bulky mesenteric nodules of small bowel and colon were seen. The histology shows mantle cell lymphoma, a rare subtype of B cell non-Hodgkin's lymphoma. She recovered well postoperatively and was started on chemotherapy (Nordic protocol) early.

Intussusception Management in Children: A 15-Year Experience in a Referral Center.

OBJECTIVE: To report a 15-y, single-center experience in the management and outcomes of ileocolic intussusception (ICI) episodes. METHODS: A retrospective study was performed in patients with ICI episodes, who were treated at a single quaternary referral center from 2005 to 2019. Data evaluated included patient demographics, clinical presentation, treatment modalities, hospital stay, complications, and outcomes. RESULTS: A total of 546 ICI episodes (66.1% males) were included, with a median age at diagnosis of 15 mo. Enema reduction was performed in 478 patients (87.6%), with an overall success rate of 85.8%. Hydrostatic saline enema was the most effective method (89.3%) when compared to pneumatic (80.6%) or barium enema (79.8%), this difference being statistically significant (p = 0.031). No associated complications were observed during nonoperative reduction. Surgical treatment was performed in 101 patients, in whom 36 bowel resections were performed. Postoperative complications were reported in 6 patients (5.9%). Hospital stay was significantly longer in patients with operative management (median 5 d vs. 1 d; p < 0.001). CONCLUSIONS: Nonoperative management has a high overall success rate and low complication and recurrence rates. Saline enema reduction presents the highest effectiveness, and should be considered the first-line treatment.

An Infant with COVID-19-Associated Intussusception.

Intussusception is the most common cause of bowel obstruction in infants four to ten months old and is commonly idiopathic or attributed to lymphoid hyperplasia. Our patient was a 7-month-old male who presented with two weeks of intermittent abdominal pain associated with crying, fist clenching and grimacing. Ultrasound demonstrated an ileocolic intussusception in the right abdomen. Symptoms resolved after contrast enemas, and he was discharged home. He re-presented similarly the next day and was found to be COVID-19 positive. Computed tomography scan demonstrated a left upper quadrant ileal-ileal intussusception. His symptoms spontaneously resolved, and he was discharged home. This suggests that COVID-19 may be a cause of intussusception in infants, and infants presenting with intussusception should be screened for this virus. Additionally, recurrence may happen days later at different intestinal locations. Caregiver education upon discharge is key to monitor for recurrence and need to return.

Recurrent Ileo-ileal Intussusception Caused by Inflammatory Fibroid Polyp: A Rare Case Report.

An inflammatory fibroid polyp is a rare benign lesion of the gastrointestinal tract, which can cause obstruction or intussusception when it reaches a large diameter. We present a case of a 46-year-old female admitted to our clinic with recurrent ileus attacks. We performed segmental resection of the small bowel due to a 3-cm pedunculated polypoid lesion located in the terminal ileum that caused ileo-ileal intussusception and whose pathology was reported as an inflammatory fibroid polyp. In adults presenting with ileus, the possibility of intussusception should be kept in mind.

Midazolam premedication in ileocolic intussusception: a retrospective multicenter study.

Ileocolic intussusception is a common cause of bowel obstruction. When spontaneous reduction does not occur, non-operative management through enema reduction is necessary. Despite the evidence indicating that sedatives favor success in the reduction, their use is still not a common practice. To determine if midazolam (MDZ) before enema improves the rate of procedure success, we retrospectively reviewed charts of patients admitted to two Italian pediatric emergency departments. Outcome measures were the success rate of the enema, recurrence, and need for surgery. Patients were grouped according to the use of MDZ or not, before hydrostatic reduction attempt. We included 69 and 37 patients in the MDZ and non-MDZ groups, respectively. The two groups did not differ in demographics, clinical characteristics, and ultrasound findings. Intussusception reduction after the first enema attempt occurred in 75% (MDZ group) and 32.4% (non-MDZ group) of patients (P < .001); 27.9% (MDZ group) and 77.8% (non-MDZ group) of patients underwent surgery (P < .001). Among them, spontaneous reduction of intussusception during the induction of general anesthesia occurred in 31.6% and 42.9% of patients, respectively (P .43). Multivariate logistic regression analysis showed that only MDZ had a positive effect on the result of the enema (OR 7.602, 95%CI 2.669-21.652, P < .001). CONCLUSION: Procedural sedation with MDZ for enema reduction of intussusception can increase the success rate and lead to a better management of patients. WHAT IS KNOWN: • Despite the evidence of the usefulness of sedatives in the reduction of intussusception, their use is still not a common practice. WHAT IS NEW: • Midazolam during enema reduction of intussusception can increase the success rate and consequently lead to better management of patients.

[A young teenager with chronic postprandial emesis]. / Een jonge tiener met chronisch braken na het eten.

A girl, 11 years of age, presented with progressive abdominal pain and emesis after eating since 9 months. Her blood count only showed an iron deficiency anaemia. Diagnostic work-up suggested an ileo-ileal intussusception caused by a pedunculated polyp. Diagnosis was confirmed by laparoscopic-assisted resection of the involved small bowel.
