[Intestinal Mantle Cell Lymphoma Complicated With Ileocecal Intussusception in Adults:Report of One Case].

Intestinal mantle cell lymphoma complicated with intussusception is rare in clinical practice,lacking specific clinical manifestations.CT and colonoscopy are helpful for the diagnosis of this disease,which need to be distinguished from colorectal cancer,Crohn's disease,and other pathological subtypes of lymphoma.The diagnosis still needs to be confirmed by pathological examination.This paper reports a case of intestinal mantle cell lymphoma complicated with ileocecal intussusception in an adult,aiming to improve the clinical and imaging doctors' understanding of this disease.

[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.

Ileo-Ileal Intussusception Secondary to Neuroendocrine Tumor in Adult Patient.

BACKGROUND Intussusception occurs when a proximal region of the intestine telescopes into a distal region. It is more common in the pediatric population, with only 5% of cases occurring in adults. The most frequent causes of adult intussusception are malignancy, polyps, or diverticula. A very rare cause is neuroendocrine tumor (NET). NETs are a diverse group of neoplasms that arise from endocrine cells throughout the body. Here, we present a case of a patient who presented with ileo-ileal intussusception due to a T3N1 NET, grade 1. CASE REPORT A 60-year-old man with a medical history of peptic ulcer disease presented for evaluation of lower abdominal pain, dark "maroon" colored stools, and hematemesis for the past 2 days. Computed tomography (CT) of the abdomen and pelvis showed ileo-ileal intussusception. Exploratory laparotomy revealed a small bowel mass approximately 30 cm from the ileocecal valve. After removal of 15 cm of small bowel and 13 lymph nodes, pathology confirmed the diagnosis of a T3N1 NET, grade 1. He was subsequently referred to the Oncology Department, where he was cleared, with no need for additional surveillance. CONCLUSIONS In adult patients presenting with nonspecific abdominal pain and concern for small bowel obstruction, a CT scan can be helpful in diagnosing intussusception. When dealing with adult intussusception, the etiology needs to be carefully investigated to search for an underlying malignancy. In rare occasions, small bowel NETs can be the cause of intussusception and can therefore be identified early, before they metastasize and present with carcinoid syndrome.

Defunctioning ileostomy for typhoid ileal perforations: Out of the frying pan into the fire?

Typhoid ileal perforation (TIP) is a common surgical emergency in low-middle income countries (LMICs). Its high surgical morbidity and mortality is due to its often late presentation or diagnosis, the patient's malnutrition, severe peritoneal contamination and unavailability of intensive care in most peripheral hospitals. This prompted the philosophy of minimizing the crisis by avoiding any repair or anastomosis, limiting the surgery in these physiologically compromised patients and performing only a temporary defunctioning ileostomy (DI) which could then be closed 10-12 weeks later.

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.

Clinical Characteristics and Etiology of Terminal Ileum Ulcers: A Retrospective Study.

Terminal ileal ulcers can have various etiologies, including Crohn's disease (CD), infections, and medication-related causes. This study aims to investigate the incidence of terminal ileal ulcers detected during colonoscopies, explore their underlying causes, and analyze their clinical, endoscopic, and histopathological characteristics. Additionally, the study aims to identify predictive factors that indicate the need for follow-up. Medical records of all patients who underwent colonoscopies, between 2009 and 2019 were retrospectively reviewed. Patients with terminal ileal ulcers, with or without ileocecal valve involvement, were included in the study. Demographic information, medication usage, symptoms, colonoscopy findings, and histopathological data of these patients were analyzed. A total of 398 patients were included in the study. Histopathological examination revealed that 243 patients (61%) had active ileitis, and 69 patients (17.4%) had chronic active ileitis. The final diagnoses for ulcers were: nonspecific ulcers in 212 patients (53.3%), CD in 66 patients (16.6%), and non-steroidal anti-inflammatory drug-induced ulcers in 58 patients (14.6%). In the multivariate analysis, the parameters predicting CD included the presence of 10 or more ulcers (odds ratio (OR) = 7.305), deep ulcers (OR = 7.431), and edematous surrounding tissue (OR = 5.174), all of which were statistically significant (P < .001). Upon final evaluation, only 66 patients (16.6%) were diagnosed with CD, while 212 patients (53.3%) had nonspecific ulcers. The majority of patients with healed ulcers exhibited pathological findings consistent with active ileitis. Therefore, it can be concluded that not all terminal ileal ulcers are indicative of CD. In those cases with active ileitis, repetitive colonoscopies should be reconsidered.

Chronic abdominal distention caused by diffuse nodular ileal and mesenteric lipomatosis: A case report.

RATIONALE: Diffuse intestinal and mesenteric lipomatosis is a rare condition characterized by the overgrowth of adipose tissue in the intestines and mesentery. This case report aims to highlight the rare occurrence of chronic abdominal distention caused by this disease and its unique invasion into the muscle layer, which has not been previously reported. PATIENT CONCERNS: A 36-year-old woman with a 7-year history of abdominal distension was admitted to our hospital's Department of Gastrointestinal Surgery. DIAGNOSE: Abdominal and pelvic computed tomography revealed diffuse small intestinal lipomatosis. INTERVENTIONS: The patient underwent surgery. We performed an open-field ilectomy involving removal of all lipomatous intestines (250 cm). OUTCOMES: During the surgery, diffuse nodular ileal and mesenteric lipomatosis was confirmed, characterized by the presence of multiple nodular lipomas within the submucosal and muscular layers. The surgical intervention involved the resection of 250 cm of the affected ileum, followed by jejunoileal anastomosis. Postoperative pathology confirmed the diagnosis, with lesions observed in both the submucosa and muscle layers. The patient showed significant improvement in symptoms, with normal intestinal function and weight gain observed over a 10-month follow-up period, and no signs of recurrence. LESSONS: Diffuse intestinal and mesenteric lipomatosis can lead to long-term abdominal distension. Additionally, it may be involved in the muscle layer of the intestinal wall. Surgery is the primary treatment option for symptomatic intestinal lipomatosis.

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.

Ileo-ileal intussusception secondary to a Peutz-Jeghers hamartomatous polyp in an infant.

We report the case of ileo-ileal intussusception secondary to a Peutz-Jeghers syndrome (PJS) hamartomatous polyp in a male infant. The patient presented with non-bilious vomiting and a single episode of passing blood in his stool. An upper gastrointestinal contrast study showed proximal bowel obstruction. At laparotomy, ileo-ileal intussusception was identified with a papillary mass acting as a lead point. The mass was resected, and a primary anastomosis was performed. The patient recovered well and was discharged on postoperative day 5. Histological assessment diagnosed a PJS hamartoma. The patient was well at 1 month follow-up. This case report describes a rare cause of intussusception in an infant that should be considered in the differential diagnosis. The diagnosis of PJS in infancy is uncommon and requires long-term follow-up.

Polypoid heterotopic gastric mucosa: in terminal ileum causing extensive lower gastrointestinal bleeding without Meckel's diverticulum: a case report.

BACKGROUND: Heterotopic gastric mucosa (HGM) can be located in various parts of the gastrointestinal tract. As a rare anomaly in the small intestine, it can become complicated by intussusception, obstruction, gastrointestinal bleeding, and even peritonitis, leading to death. CASE PRESENTATION: This case report focuses on a 12-year-old Middle Eastern boy who presented with hematochezia and abdominal pain for a couple of days. A tagged Red blood cell (RBC) scan and Technetium scan revealed gastrointestinal bleeding at the lower abdomen, highly suggestive of the diagnosis of Meckel's diverticulum. Subsequently, exploratory laparotomy revealed contiguous and scattered mucosal lesions with multiple polyps of various sizes in the terminal ileum. Meckel's diverticulum was absent, and the patient was treated with resection and primary anastomosis. The resected tissue revealed extensive ectopic gastric mucosa and polypoid tissues. The patient recovered uneventfully and was discharged four days after the surgery. The symptoms did not recur within six months after his surgery. CONCLUSION: Our case demonstrated that despite the rarity of multiple polypoid gastric heterotopias in the terminal ileum, it should be considered as one of the differential diagnoses of gastrointestinal tract bleeding.

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.

Lithopedion causing intestinal obstruction in a 71-year-old woman: A case report / Litopedia causando obstrução intestinal em idosa de 71 anos: relato de caso

Abstract Ectopic pregnancy is the leading cause of pregnancy-related death during the first trimester, and it occurs in 1 to 2% of pregnancies. Over 90% of ectopic pregnancies are located in the fallopian tube. Abdominal pregnancy refers to an ectopic pregnancy that has implanted in the peritoneal cavity, external to the uterine cavity and fallopian tubes. The estimated incidence is 1 per 10,000 births and 1.4%of ectopic pregnancies. Lithopedion is a rare type of ectopic pregnancy, and it occurs when the fetus from an unrecognized abdominal pregnancymay die and calcify. The resulting "stone baby" may not be detected for decades andmay cause a variety of complications. Lithopedion is a very rare event that occurs in 0.0054% of all gestations. About 1.5 to 1.8% of the abdominal babies develop into lithopedion. There are only ~ 330 known cases of lithopedion in the world. We describe a lithopedion that complicated as intestinal obstruction in a 71-year-old woman.

Resumo A gravidez ectópica é a principal causa de morte materna no primeiro trimestre, e ocorre em 1 a 2% das gestações. Mais de 90% ocorrem nas tubas uterinas. Gravidez abdominal refere-se à gravidez ectópica implantada na cavidade peritoneal, externamente ao útero e às tubas uterinas.Aincidência estimada éde 1 por 10mil nascimentos e 1,4%das gravidezes ectópicas. A litopedia é um tipo raro de gravidez ectópica, e ocorre quando o feto de uma gravidez abdominal não reconhecida morre e se calcifica. O "bebê de pedra" resultante pode não ser detectado por décadas, e pode causar complicações futuras. A litopedia é um evento muito raro que ocorre em 0,0054% de todas as gestações. Cerca de 1,5 a 1,8% dos bebês abdominais se tornam litopédios. Existem somente cerca de 330 casos conhecidos de litopedia no mundo. Descrevemos uma litopedia que se agravou, tornando-se uma obstrução intestinal, em uma idosa de 71 anos.
