Introduction: Jejunogastric intussusception (JGI) is a rare but potentially lethal complication following gastrectomy or gastrojejunostomy surgeries. Diagnosis of this condition can be challenging due to its rarity and non-specific symptoms. This article presents a case report of a 60-year-old male with a history of trans mesocolic gastrojejunostomy who developed acute symptoms of JGI. Case report: The patient presented with acute epigastric pain, vomiting, and hematemesis. Physical examination and laboratory tests indicated dehydration, tachycardia, and leukocytosis. Computed tomography (CT) revealed intussuscepted loops within the stomach. Emergency laparotomy was performed, and the intussusception was manually reduced without the need for resection. The patient recovered well and was discharged five days post-surgery. Discussion: Retrograde jejunogastric intussusception is a rare complication, often occurring years after gastric surgery. It can be classified into acute and chronic forms, with the former presenting with intense pain and potential hematemesis. The condition can arise in different surgical contexts and even spontaneously. The cause of JGI remains unclear, but factors such as hyperacidity, abnormal motility, and increased intra-abdominal pressure have been implicated. Diagnosis can be made through endoscopy or alternative imaging modalities such as CT. Surgical intervention is the treatment of choice, with various options available based on intraoperative findings. Conclusion: Retrograde jejunogastric intussusception is challenging to diagnose and treat due to its rarity and lack of understanding of its causes. Imaging techniques and endoscopy play important roles in diagnosis, while surgery remains the primary treatment option. Vigilance is necessary among medical professionals to consider JGI in cases of acute abdominal pain and vomiting following gastric surgery, allowing for prompt diagnosis and intervention to prevent bowel necrosis. Further research is needed to establish optimal surgical strategies and evaluate recurrence rates. [ABSTRACT FROM AUTHOR]

A group of diseases resulting from the abnormal aggregation of amyloid fibrils, mainly in the extracellular spaces of tissues, is known collectively as amyloidosis. Clinical presentations of gastrointestinal (GI) amyloidosis are mainly GI bleeding, malabsorption, protein-losing enteropathy, and dysmotility. Here, we describe an 87-year-old woman presenting with acute onset of sharp, constant, and non-radiating epigastric pain that was accompanied by nausea or vomiting. After a thorough investigation, we finally found an isolated jejunojejunal intussusception by laparotomy. The pathological study revealed massive small bowel involvement by amyloidosis in immunostaining. To our knowledge, this is the first report of small intestinal obstruction resulting from intussusception due to intraluminal amyloid polypoid nodules, as the first presentation of light-chain amyloidosis. Amyloidosis should be considered in old patients with intraluminal masses of the proximal small bowel. [ABSTRACT FROM AUTHOR]

Peutz--Jeghers syndrome (PJS) is characterized by mucocutaneous pigmentation with multiple hamartomatous polyps of the gastrointestinal tract and/or a familial history with autosomal dominant inheritance pattern having incomplete penetrance, with some cases arising from spontaneous mutations. We present this case of a 12-year-old female who presented with jejunojejunal intussusception and on exploration revealed a polypoidal mass around 50 cm from duodenojejunal flexure acting as a lead point. A segmental jejunal resection with anastomosis was performed and histopathology confirmed a solitary Peutz--Jeghers (PJ) hamartomatous polyp. She neither had mucocutaneous pigmentation nor family history of PJS or any other polyps anywhere in the gut on further evaluation by endoscopies. A solitary PJ polyp in the jejunum is a rare entity, and to the best of our knowledge, only around 13 cases have been reported in world literature so far. Regular follow-up is essential in young children, so that future manifestations of the PJS are not missed. [ABSTRACT FROM AUTHOR]

Introduction: Jejunojejunal intussusception after Roux-en-Y gastric bypass (RYGBP) for morbid obesity is a rare but potentially catastrophic complication. There are limited data regarding the incidence of intussusception and the different surgical options for management of this disease.Methods: This is a retrospective review of all patients that underwent RYGBP and subsequently developed intussusception at the jejunojejunostomy. Data were collected between 1/1/2008 and 5/31/2018 and included demographics, details related to the index procedure, presentation, and management of intussusception. Perioperative outcomes and complications were also collected.Results: 665 patients underwent RYGBP. A total of 34 patients developed intussusception, with 31 (4.7%) of them having undergone RYGBP in our hospital. Demographics included age, gender, and BMI at both the index surgery and at the time of intussusception. The jejunojejunostomy was created during RYGBP using a linear stapler in all patients with 64.5% of them achieving a length of 90 mm. All intussuscepted patients presented acutely with abdominal pain. All but one patient required surgical intervention. 42.4% of the patients were found to have intraoperative intussusception which appeared to be retrograde in 78.6% of them. Reduction followed by enteropexy or just enteropexy was performed in 20 patients (60.6%) that required surgery. No immediate post-operative complications were noted but 8 patients (26.5%) had recurrence of intussusception requiring another surgical intervention. In the reoperated group, 75% of the patients were treated with reduction followed by enteropexy or just enteropexy.Conclusions: This is the largest case series describing jejunojejunal intussusception following RYGBP. All patients that developed intussusception had jejunojejunostomy length greater than 60 mm. The most commonly performed surgical repair was reduction of the intussuscepted segment (if present) followed by enteropexy. Jejunojejunostomy length greater than 60 mm might be associated with the occurrence of intussusception and could explain the higher incidence noted in our series. Minimal intervention with enteropexy can offer effective treatment for most patients. [ABSTRACT FROM AUTHOR]

Background: Jejunogastric intussusception (JGI) is a rare but severe complication after gastric surgery. JGI can occur from a few days to 55 years postoperatively and has a reported incidence of < 0.1% in patients who undergo gastric surgery. We firstly report a male patient with duodenal cancer who underwent Whipple's procedure with side-to-side gastrojejunostomy and who subsequently developed JGI. A literature review is provided.Case Presentation: A 68-year-old man was admitted to our emergency department with left upper quadrant abdominal pain and hematemesis of 4 h' duration. He had undergone Whipple's procedure (duct-to-mucosa pancreaticojejunostomy and side-to-side gastrojejunostomy) with B-II reconstruction for duodenal papillary adenocarcinoma 5 years earlier. His vital signs were stable with a blood pressure of 163/93 mmHg, temperature of 37.0 °C; and heart and respiratory rates of 86 per/min and 20 per/min, respectively. Physical assessment showed mild tenderness in the left upper quadrant, only. A complete blood count showed white cell and platelet counts of 11.69 × 103/L and 196 × 103/L, respectively, and a hemoglobin level of 13.5 g/L. Abdominal computed tomography (CT) suggested a retrograde intussusception of the intestines into the stomach with dilatation of the remnant stomach. The patient immediately underwent exploratory laparotomy, which revealed a 20-cm retrograde efferent limb at the remnant stomach that had travelled through the previous gastrojejunostomy. There was no evidence of malignancy. We manually reduced the intussuscepted loop using gentle traction, and the viability of the intestinal loop was preserved. The patient had an uneventful postoperative recovery.Conclusion: JGI is a rare but potentially fatal complication after gastric surgery, especially following Whipple's procedure. Early diagnosis and treatment are crucial, and surgery is considered the most effective treatment for JGI. [ABSTRACT FROM AUTHOR]

Jejuno-gastric intussusception is a rare but lethal complication of gastric surgeries with a reported incidence of 0.15%. A high index of suspicion is required to diagnose this condition in a patient with a history of gastric surgery. With advances in minimal access surgery, reduction of the intussusceptum is possible through laparoscopy or endoscopy. We present an elderly male who had undergone a Billroth II procedure before 27 years. The patient was diagnosed with jejuno-gastric intussusception based on ultrasound and endoscopic findings. The patient was successfully managed under laparoscopy. [ABSTRACT FROM AUTHOR]

Peutz-Jeghers syndrome (PJS) is an autosomal dominant disorder characterized by intestinal hamartomatous polyps in association with skin and mucosal macular melanin deposition. There is a lifetime chance of 93% of cancers when all cancers are combined and the incidence of the disease is variable between 1 in 8300 and 1 in 280,000 live births (Daniell et al., Familial Cancer 17(3):421-427, 2018). Here, we present a 14-year-old Indian boy presenting to surgical emergency with intestinal obstruction secondary to jejunojejunal intussusception for which resection and anastomosis were done. Post-operative histopathological examination showed a single polyp leading to intussusception. He classically showed mucocutaneous pigmentation on general examination. Early identification of Peutz-Jeghers syndrome on a routine visit to healthcare can decrease complications like intestinal obstruction and help in starting early surveillance for cancers.

We report a case of intussusception presenting as bilious vomiting in a term neonate. Intussusception should be considered as a differential diagnosis even in the neonatal period. Ultrasound scan may help in early diagnosis. This condition needs to be operated early as delayed treatment may lead to bowel necrosis. [ABSTRACT FROM AUTHOR]

Intestinal lipomatosis is an extremely rare disease that is characterized by numerous lipomas of the intestine. This condition is usually asymptomatic, but clinical presentation is determined by intussusceptions, volvulus, or ulceration. We report a case of intestinal lipomatosis of the jejunum with volvulus and describe the characteristic computed tomography findings that were used to make a preoperative diagnosis.

Inflammatory fibroid polyp (known also as Vanek's tumor) is a type of localized, non-neoplastic inflammatory pseudotumor or inflammatory myofibroblastic tumor that occurs most commonly in the stomach but also in the small and large bowel. It is a documented cause of intussusception in adults. We report a case of a 40-year-old woman who presented with severe, postprandial abdominal pain followed by projectile vomiting over a period of three days. Ultrasonography demonstrated a solid and echogenic mass surrounded by the typical mural layers of an invaginated jejunum. She underwent urgent laparotomy and resection of an 18 cm tumor from the distal jejunum. The immunohistopathological diagnosis after segmental jejunal resection was a jejunal inflammatory fibroid polyp. Although inflammatory fibroid polyps are seen very rarely in adults, they are among the probable diagnoses that should be considered in obstructive tumors of the small bowel causing intussusceptions.

Epidemiologic studies show that sleep apnea increases risks for cardiovascular disease independently of individuals' demographic characteristics or risk markers i.e., smoking, alcohol, obesity, diabetes, dyslipidemia, atrial fibrillation, and hypertension. Individuals with severe sleep apnea are at increased risk for pulmonary arterial hypertension. The underlying mechanisms explaining associations between obstructive sleep apnea and pulmonary arterial hypertension are not entirely delineated. Several intermediary mechanisms might be involved including sustained sympathetic activation, intrathoracic pressure changes, and oxidative stress. Other abnormalities such as disorders in coagulation factors, endothelial damage, platelet activation, and increased inflammatory mediators might also play a role in the pathogenesis of pulmonary hypertension and cardiovascular disease. Linkage between obstructive sleep apnea and pulmonary arterial hypertension is corroborated by evidence that treatment of sleep apnea with continuous positive airway pressure reduces systolic blood pressure, improves left ventricular systolic function, and diminishes platelet activation. Several systematic studies are necessary to explicate complex associations between sleep apnea and pulmonary hypertension. [ABSTRACT FROM AUTHOR]

Introduction: Peutz-Jeghers syndrome is a rare autosomal dominantly inherited disease characterized by mucocutaneous pigmentations and gastrointestinal polyps. The polyps are located predominantly in the small intestine and usually cause intussusceptions. Adult intussusception caused by Peutz-Jeghers syndrome occurs very rarely. The purpose of this study was to analyze the clinical characteristics, preoperative diagnosis, and surgical management of Peutz-Jeghers syndrome associated with acute intussusception in adult patients.Discussion: Consecutive patients with the postoperative diagnosis of acute intussusception caused by Peutz-Jeghers syndrome from 1995 to 2010 were reviewed retrospectively for this study. Data concerning clinical considerations, morphological examinations, and surgical procedure were analyzed. Different clinical manifestations were presented in patients with intussusception due to Peutz-Jeghers syndrome. Computed tomography associated or not with ultrasonography may be the most accurate examination for acute intussusceptions caused by Peutz-Jeghers syndrome. Surgical intervention is the first choice regimen in acute intussusceptions caused by Peutz-Jeghers syndrome. Prophylaxis and polypectomy of the entire small bowel is a worthy way in Peutz-Jeghers syndrome patients to reduce the frequency of laparotomies. [ABSTRACT FROM AUTHOR]

Aim: This study aims to compare management strategy and outcomes of paediatric ileocolic intussusceptions (ICI) versus small-bowel intussusceptions (SBI). Methods: Hospital charts of patients with intussusceptions between January 1999 and June 2006 were reviewed retrospectively. Results: A total of 135 patients with the diagnosis of intussusceptions were found in the database. In 111 patients the diagnosis was confirmed using ultrasound. The median age of the patients was 2.25 years (range 9 weeks-10 years). ICI were documented in 83 patients (74.8%) and SBI in 28 (25.2%). Spontaneous reductions were observed in 11 of 83 (13.3%) ICI and 18 of 28 (64.3%) SBI. Pneumatic reductions were attempted and were successful in 61 of 67 (91%) ICI and 6 of 7 (85.7%) SBI. Surgery was performed in 11 of 83 (13.3%) ICI and 4 of 28 (14.3%) SBI; with 2 of 83 (2.4%) ICI and 3 of 28 (10.7%) SBI patients requiring bowel resections. The median age of patients requiring surgery was 9 months in ICI and 6 years in SBI. Conclusion: There are differences in ICI and SBI with regard to spontaneous reductions, and bowel resection, and age with regard to surgery and bowel resection. The treatment efficacy depends on time of presentation, intussusception type, pathologic lead points, ultrasound/colour Doppler interpretation and expertise in reduction techniques.

The article presents a panel discussion involving a number of doctors investigating the case of an African American girl diagnosed with syncope. A summary of the patient's medical history is presented. The doctors addressed some of the factors that should be considered before providing their differential diagnosis. Pediatrician Jennifer Trainor described the typical story for vasovagal syncope.

Introduction: Intestinal intussusception is very rare in adults and, unlike in children, it is due to an organic cause, mainly benign or malignant tumors, in 90 % of cases. Recurrent intussusception in an adult is even more exceptional, and in the case reported it was due to repeated occurrence of intestinal pseudopolyps, which is exceptional according to the literature. Preoperative diagnosis is difficult, and surgery is always indicated because a tumor is usually present. The surgical procedure may be controversial, as some would prefer desintussusception before resection, while others would advocate initial resection because of the risk of dissemination if a malignant lesion exists.Case Presentation: We report the case of a 34-year-old Caucasian man who underwent emergency laparoscopic surgery for intestinal obstruction and was found to have a jejunal intussusception. Polyps or pseudopolyps, some of them large and causing the intussusception, were seen in the surgical specimen. Our patient had also undergone surgery for intussusception 10 years before, after which the pathological report also noted the presence of these formations.Conclusions: Recurrent intussusception in adults due to the presence of intestinal pseudopolyps is exceptional and, to the best of our knowledge, this is the first such case reported.

We report on a 61-year-old man who was referred to the accident and emergency department with recurrent episodes of vomiting and diffuse abdominal pain for 1 week prior to admission. The patient also reported frequent constipation and intermittent melaena. He had undergone tumour nephrectomy for metastatic renal clear cell carcinoma 3 years before and had received sequential vascular endothelial growth factor receptor and mammalian target of rapamycin-targeted therapies. The abdominal computed tomography scan showed small bowel obstruction due to triple intussusception of the proximal jejunum and several large intra-luminal tumour masses. Intra-operative findings were five intramural masses 15 cm distal to the ligament of Treitz over a total length of 50 cm. A primary en bloc resection with an end-to-end anastomosis was carried out. The postoperative course was uneventful. [ABSTRACT FROM AUTHOR]

Retrograde jejunogastric intussusception is an unusual long term complication of gastro-jejunostomy or Billroth-II reconstruction. Acute and chronic forms have been well recognised with the acute form being fatal without timely surgical intervention. The imaging findings are diagnostic, and an established emergency imaging protocol would be very useful for clinical decision making, as the clinical features are usually ambiguous. We present the systematic imaging description in a case of retrograde (type II) jejunogastric intussusception with strangulation following gastric bypass procedure. [ABSTRACT FROM AUTHOR]

Intussusception is an important cause of abdominal pain in the paediatric population and is the most common abdominal emergency in early childhood. Intussusception in adults is, however, rare and can lead to diagnostic challenges for admitting physicians/surgeons. We present a case of a 76-year-old lady with history of a recent myocardial infarction and vasculitis presenting with melaena and bleeding per rectum, with suspicion of haematochezia. She complained of abdominal pain but was not clinically obstructed. Gastroscopy performed was negative. Colonoscopy was attempted; however, it was inconclusive because of active bleeding. A CT angiogram of the abdomen was performed, which showed a jejunal intussusception. There was no evidence of vasculitis or small bowel obstruction. She was not considered fit for surgery and was managed conservatively. [ABSTRACT FROM AUTHOR]

Multiple simultaneous intussusception is a peculiar variety of intussusception. The condition is reported in older children and adults. The occurrence in neonates is an interesting situation. We present one such neonate who had a simultaneous ileo-colic and ileo-ileal intussusception without any specific cause. A review of existing literature revealed only three neonates. The terminology and various aspects of the condition are discussed. [ABSTRACT FROM AUTHOR]

Malignant peripheral nerve sheath tumors (MPNST) are defined as any tumor arising from a peripheral nerve or showing nerve sheath differentiation. The majority of these tumors arise on the trunk, extremities, or head and neck region. The literature to date has fewer than 14 cases of MPNST arising in the gastrointestinal tract, and only two cases were ever reported in the small intestine, one of which was a recurrent disease. In this paper, we report the first US case of an MPNST arising in the small intestine and presenting as intussusception. [ABSTRACT FROM AUTHOR]

Small bowel submucosal lymphangioma in children is extremely rare. We present the case of a 5-year-old boy with intussusception secondary to a submucosal lymphangioma in the jejunum. To the best of our knowledge, this is the first report of intussusception secondary to a small intestinal submucosal lymphangioma in a child. [ABSTRACT FROM AUTHOR]

Ten children developed intussusception after laparotomy. The bowel obstruction caused by the intussusception was evident within 8 days of major laparotomy in 8 children and within 39 days in the other two. It developed after the usual postoperative laparotomy ileus, and did not respond to normal non-operative treatment not even to a barium enema. There was one palpable abdominal mass and no rectal bleeding. Only at surgery was the correct diagnosis made. Eight of 10 intussusceptions affected only the small-bowel; most of them were ileoileal, but 2 were ileocolic. Seven of the 10 intussusceptions needed only manual reduction. Postoperative recovery was uneventful. [ABSTRACT FROM AUTHOR]

Posttransplant lymphoproliferative disorder (PTLD) is not uncommon in pediatrics. This case report describes a case of intestinal intussusception that occurred secondary to lymphoid hyperplasia in a child with PTLD following a cardiac transplant. This case was unique in its presentation with multiple areas of intussusception and with need for surgical intervention. The diagnosis of intussusception secondary to lead points from PTLD should be strongly considered in pediatric transplant patients presenting with abdominal complaints. [ABSTRACT FROM AUTHOR]

The article presents a case study of a 54-year-old man with Peutz-Jeghers syndrome. He was diagnosed with jejunojejunal intussusception by computed tomography of abdomen. He was taking cefotaxime drug for treatment of the same. It discusses use of endoscopic polypectomy for treatment of the Peutz-Jeghers syndrome. [ABSTRACT FROM AUTHOR]

We are reporting a case of intestinal obstruction in a lady patient and peroperatively, it turned out to be a case of intestinal obstruction due to intussusception caused by an enterolith originating from one of multiple jejunal diverticula. It was a rare cause of intestinal obstruction, and the presentation was very rare in the literature. The diagnosis and management are thus delayed. [ABSTRACT FROM AUTHOR]

Jejunojejunal intussusception with internal herniation of the stomach through a gastrojejunostomy stoma is one of the rarest complications of the previous gastric surgery. The incidence is reported to be less than 0.1 %. An elderly male presented to the emergency room with signs of intestinal obstruction for 1 day. There was also history of appearance of a lump in the mid-abdomen. A primarily healed midline scar of the previous surgery was present; the details of which were not known. X ray abdomen in the erect posture showed multiple air fluid levels. Ultrasonography (USG) revealed dilated stomach with central hyperechogenicity with a peripheral rim of decreased echogenecity. Contrast-enhanced computed tomography (CECT) scan showed jejunojejunal intussusception with internal herniation of the stomach. On laparotomy, it was found that there was a previous gastrojejunostomy with jejunal invagination leading to gangrene of a segment. Resection anastomosis was done. The postoperative period was uneventful. [ABSTRACT FROM AUTHOR]

Introduction. Intussusception is a rare cause of bowel obstruction in adults and is usually associated with an underlying pathology, benign, or malignant. This is a report of a case of jejunojejunal intussusception secondary to non-Hodgkin's B-cell lymphoma in an adult patient. Case Presentation. A 74-year-old male with no previous significant medical history presented with symptoms of acute intestinal obstruction. A CT scan of the abdomen and pelvis revealed 2 areas of jejunojejunal intussusception, which were surgically managed successfully. Histopathological examination of the specimen revealed the presence of high grade diffuse large B-cell-type non-Hodgkin's lymphoma, and the patient was referred to the oncology team for further management. Discussion. B-cell lymphoma is a rare but well-documented cause of intussusception in adults, with most cases being at the ileocolic region. We present a rare case of jejunojejunal intussusception as the initial presentation of non-Hodgkin's B-cell lymphoma in an adult patient [ABSTRACT FROM AUTHOR]
