Ileo-ileal knot causing acute gangrenous small bowel obstruction: a case report.

BACKGROUND: Ileo-ileal knotting is a very rare cause of small bowel obstruction, and only a few reports have been published. Small bowel obstruction (SBO) is one of the most common emergency surgical conditions that require urgent evaluation and treatment and is one of the leading causes of emergency surgical admission. There are many causes of SBO that are known in general surgical practice, and these causes are different in the developing and developed worlds. CLINICAL PRESENTATION: In this article, we present a case of acute gangrenous SBO secondary to ileo-ileal knotting in a 37-year-old Ethiopian female patient after she presented with severe abdominal cramp, vomiting, and abdominal distension of 4 hours duration. The patient was operated on intraoperatively; she had gangrenous small bowel obstruction caused by ileo-ileal knotting. Later, the patient was discharged and improved after 12 days of hospital stay. CONCLUSION: Ileo-ileal knotting should always be considered in the differential diagnosis of acute small-bowel obstruction. The diagnostic difficulty and the need for urgent treatment of this condition to yield optimal results are discussed.

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.

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.

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.

Our treatment approaches in recurrent chronic intussusceptions.

BACKGROUND: Intussusception is the most common cause of intestinal obstruction between 6 months and 36 months of age. There is no defined etiology in at least 75-90% of patients. Recurrent intussusception occurs in 5-16% of all intussusceptions and the treatment strategy is controversial in this patient group. The treatment of continued recurrent intussusception is a challenging problem when no lead point is revealed despite recurrence. METHODS: We aimed to review our 10 years of experience in recurrent intussusception and describe a new operative technique for recurrent intussusception cases without any lead points. RESULTS: We, retrospectively, reviewed the data of patients with recurrent intussusception in our referral pediatric surgery clinic between 2007 and 2017. Ultrasound-guided hydrostatic reduction (UGHR) was performed on all patients. Surgery was performed on those patients who had findings of acute abdomen and complete intestinal obstruction or two failed attempts of UGHR for diagnostic purposes if a pathologic lead point was suspected based on patient findings and age. Laparoscopy or laparotomy was performed according to surgeon preference and experience. A total of 87 UGHRs were performed. Thirty-three patients were admitted to our clinic due to recurrent intussusception. The mean age was 12.75±14.14 (6-84) months, and 19 were male and 14 were female. Abdominal pain, agitation, and vomiting were common symptoms. UGHR was performed on all 33 patients on at least two different occasions. The time between the first and second UGHR treatments was 42.6±186.19 (0-899) days. The success rate of the second UGHR was 27 out of 33 patients (81.8%). Surgery was performed on six patients. Laparoscopy-assisted ileal folding and fixation to the cecal wall was performed on one patient with recurrent intussusceptions. Appendectomy was performed first, and then, ileal folding with cecal fixation was performed using 4/0 polyglactin sutures. The sutures were placed between the serosal layers of the adjacent terminal ileal loops and the cecal wall. CONCLUSION: Surgeons should try to find permanent solutions for patients with multiple recurrent intussusceptions that are resistant to treatment. Surgical excision of the lead point will help prevent recurrent intussusception. Satisfactory results can also be obtained by UGHR even in patients with recurrences. Laparoscopy is helpful in diagnosis, detection of lead points, and treatment of irreducible intussusception. This new operative technique can be satisfactory for recurrent intussusceptions without any lead points.

[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.

Combined Ileoileal and Ileocolic Intussusception Secondary to Inflammatory Fibroid Polyp in an Adult: A Case Report.

Intestinal intussusception is relatively rare in adults and accounts for approximately 5% of intestinal obstruction. Intussusception is classified into subtypes according to the location, including ileoileal, ileocolic, ileo-ileocolic, colo-colic, jejuno-ileal, or jejuno-jejunal; the ileocolic type being the most common. However, intussusception of a combination of different subtypes has rarely been reported in the available literature. Abdominal computed tomography (CT) is the most accurate tool to evaluate intestinal intussusception. The pathological lead point in the intestine typically results in adult intussusception. Surgical intervention is usually adopted in cases of adult intussusception due to a high incidence of underlying bowel malignancy. An inflammatory fibroid polyp (IFP) is one of the uncommon benign neoplasms of the gastrointestinal (GI) system, which can result in intestinal intussusception. Herein, we present a case of a 50-year-old female with combined ileoileal and ileocolic intussusception, which was initially diagnosed by abdominal CT. Therefore, laparoscopic right hemicolectomy surgery was performed, confirming the final diagnosis as ileoileal and ileocolic intussusception secondary to IFP.

Ultrasonographic diagnosis of ileo-ileal intussusception secondary to Vanek's tumor.

Intussusception is a common condition of bowel obstruction in pediatric patients. However, 5% of all cases occur in adults, mostly aged over fifty, with no difference based on sex, representing about 1% of all causes of bowel obstruction. Compared to pediatric population, it is triggered by a pathologic lead point in about 85% of cases, represented in 60% of cases by malignant and benign neoplasms. Among these neoplasms, an inflammatory fibroid polyp (IFP), a benign neoplastic submucosal lesion also known as Vanek's tumor, is considered a very uncommon cause of adult intussusception. Clinical presentation could differ by location and size of tumor, and may include abdominal pain, nausea, vomiting, diarrhea or constipation, bleeding, weight loss, palpable abdominal mass, bowel obstruction, and gastrointestinal bleeding. Considering its common and non-specific symptoms, radiologic imaging plays a key role in the diagnosis of an IFP, especially computed tomography (CT) scan, which represents the most sensitive modality to confirm intussusception. However, bowel sonography (BS) has become an accurate procedure in various pathological intestinal diseases, also including intussusception. In this paper, we report a rare case of ileo-ileal intussusception secondary to Vanek's tumor diagnosed by BS.

A systematic review of symptomatic hamartomas of the jejunum and ileum.

INTRODUCTION: Gastrointestinal hamartomas are rarely encountered benign growths made of an abnormal mixture of tissues normally found in the body where the growth occurs. Most hamartomas are asymptomatic and diagnosed incidentally. Evidence regarding symptomatic hamartomas of the jejunum and ileum is limited and restricted to anecdotal case reports. We aim to provide a contemporary overview to clarify various aspects linked to symptomatic hamartomas, helping aide management and clinical decision-making. METHODS: The search terms 'small bowel', 'small intestine', 'jejunum' and 'ileum' were combined with 'hamartoma'. Embase, Medline, PubMed searches and Google Scholar hand-searches were conducted. All English language papers from 1 January 2000 to 1 June 2020 were included. RESULTS: In total 39 cases were reviewed: 29 adults and 10 paediatric (0-16 years). Presenting symptoms included abdominal pain (87%), vomiting (56%), gastrointestinal bleeding (20.5%) and weight loss (5%); 36 of 39 cases (92%) presented as emergencies. Diagnostic investigations included: abdominal x-ray (49%), endoscopy (38%), computed tomography (56%), magnetic resonance imaging (5%), contrast study (15%) and video capsule endoscopy (5%). Initial management strategy was either open (30) or laparoscopic (7) surgery or endoscopy (2). All cases required surgery for definitive management. Twenty-five cases recorded hamartoma size, and mean maximum diameter was 3.56cm (1.2-8cm) with stricturing in seven cases. Nine of the 39 cases were associated with hamartomatous syndromes. Two mortalities were recorded. CONCLUSIONS: This is the first published review addressing symptomatic hamartomas of the jejunum and ileum. New data relating to demographic cohort, symptom profile, investigations, management strategies, and morbidity and mortality provide greater insight to those encountering this challenging clinical finding in the future.

Ileocolic Intussusception in a Woman: A Case Report and Literature Review.

BACKGROUND Intussusception is a rare pathological entity in adults and remains a diagnostic challenge for clinicians, as it shares many clinical signs and symptoms with other morbid conditions (including appendicitis, abdominal hernias, colic, volvulus, and Meckel diverticulum). High clinical suspicion and use of appropriate imaging techniques are essential for early diagnosis and treatment of intussusception. Surgical intervention is the treatment of choice in cases of sustained and persistent invagination. CASE REPORT We present the case of a 65-year-old woman with a medical history of Crohn's disease, diabetes mellitus type II, hypertension, and rheumatoid arthritis. She was hospitalized for diarrhea, fatigue, and anemia. Computerized tomography of the abdomen and a colonoscopy revealed telescoping of the ileum, ileocecal valve, and part of the ascending colon inside the terminal segment of the ascending colon. The antegrade ileocolic intussusception was treated by performing a right hemicolectomy. The pathologic examination of the excised intestine showed mucosal lesions compatible with Crohn's disease, an inflammatory fibroid polyp at the terminal section of the ileum, and a low-grade appendiceal mucinous neoplasm. CONCLUSIONS Regardless of the etiology, when the normal motility of the intestine is altered, it can lead to invagination. Although intussusception is rare, it must always be part of the differential diagnosis for a patient presenting with constant abdominal pain.

Adult Intestinal Intussusception: Practical Issues and Concerns.

CASE SUMMARY: A 37-year-old woman with no relevant past medical history presented to the emergency department after a 2-day-long period of crampy abdominal pain with an inability for oral intake because of persistent vomiting. The physical examination was unremarkable. Abdominal CT scan with water-soluble oral contrast revealed an ileocecal intussusception (Fig. 1). Because the patient was hemodynamically stable and no abdominal tenderness was found, a delayed surgical intervention was planned with laparoscopic approach. During intervention, the intestinal invagination was reduced, a cecal neoplasm suspected, and a right hemicolectomy with complete mesocolic excision was performed (Fig. 2). Postoperative recovery was uneventful, with discharge on postoperative day 5. The definite pathological report showed well-differentiated colon adenocarcinoma pT2N1aMx, with 1 of 49 positive lymph nodes.
