The diagnosis and treatment of adult intussusception

Gastroduodenal intussusception in an elderly patient: A rare case

Gastroduodenal intussusception is a rare but important cause of gastric outlet obstruction, particularly in elderly patients. We present the case of an 81-year-old female who arrived at the emergency department with complaints of epigastric pain, nausea, and vomiting. A CT scan revealed gastroduodenal intussusception, while subsequent endoscopy identified a submucosal mass, raising suspicion for either a gastrointestinal stromal tumor (GIST) or pancreatic rest. This case report highlights the diagnostic process, therapeutic considerations, and clinical outcomes, with a review of the relevant literature.

Ileocolic Intussusception Due to Mucinous Adenocarcinoma in a Middle-Aged Man: A Rare Presentation

The invagination, or telescoping, of one segment of the colon into another distal segment is the hallmark of the medical disorder known as intussusception. The invaginated portion of the intestines may be propelled forward by peristaltic movements, which may result in bowel blockage, ischemia, and long-term necrosis. The precise cause of intussusception is ambiguous, particularly in cases with no clear lead point. Dysrhythmic contractions and lymphoid hyperplasia are nevertheless linked to the pathophysiology. A 54-year-old male patient arrived at our emergency department after experiencing abdominal pain that had been progressively increasing for the past three days. The patient had a history of previous appendectomy. It was reported that the pain was abrupt and severe and that it grew worse with each meal or drink. During the physical examination, abdominal distension, discomfort, central guarding, and a small palpable mass measuring 3 x 3 cm were identified. Contrast-enhanced CT scans revealed a 7 cm segment intussusception of the terminal ileum into the cecum and ascending colon. Furthermore, the cecum, mesentery, vasculature, and subsequent nodes were all involved in a significant amount of wall edema. During an emergency laparotomy, a terminal ileocolic intussusception was identified. A restricted segmental resection of the terminal ileum was conducted after the adhesiolysis. Subsequently, an end ileostomy was performed. Ileocolic obstructive intussusception is a rare adult condition caused by a mucinous adenocarcinoma. This case provides a unique perspective on the condition. Consequently, physicians must be vigilant for indications of obstructive intussusception in various colon regions that may suggest malignancy.

Adult gastro-gastric intussusception; a case report

INTRODUCTION AND IMPORTANCE

Intussusception in the proximal bowel is extremely rare, with only a few reported cases of gastroduodenal intussusception (GDI). Gastrogastric intussusception is the rarest form of intussusception in adults. Here, we present an exceptionally rare case of gastro-gastric intussusception caused by a gastric Gastrointestinal Stromal Tumor (GIST).

CASE PRESENTATION

A 36-year-old male presented with acute abdominal pain, suggestive of intussusception. The preoperative evaluation was unable to pinpoint the exact location or cause of the intussusception.

CLINICAL DISCUSSION

Intraoperative diagnosis of gastro-gastric intussusception was made, and the patient was treated with a gentle reduction of the intussusception, followed by a distal gastrectomy with Billroth I anastomosis. He was relieved of his symptoms and has been recurrence-free for the past two years.

CONCLUSIONS

Gastro-gastric intussusception is an exceedingly rare type of foregut intussusception, which presents with non-specific clinical presentation and commonly occurs in the presence of an underlying pathology. A delay in diagnosis and treatment may be fatal, so a high index of suspicion and early surgical management is paramount.

A Rare Case of Small Bowel Intussusception Secondary to Angiomyxoma With Concurrent Ovarian Cystadenofibroma

Adult intussusception is an uncommon condition that constitutes a small percentage of cases of bowel obstruction in adults. Unlike its paediatric counterpart, it is often linked to an underlying pathology, necessitating surgical interventions for diagnosis and treatment. This report discusses a case involving a 54-year-old woman who presented with symptoms of small bowel obstruction, including abdominal pain, nausea, and constipation, along with a one-month history of weight loss. Imaging revealed small bowel intussusception and an abnormal pelvic mass. Surgical intervention confirmed an ileo-ileal intussusception with an intraluminal mass as the lead point and a concurrent ovarian mass. The histopathological analysis identified the lead point as a benign small bowel angiomyxoma alongside a benign ovarian cystadenofibroma. The patient recovered well following laparoscopic reduction of the intussusception, bowel resection, and bilateral salpingo-oophorectomy. This case highlights the diagnostic challenges posed by adult intussusception due to its nonspecific presentation and underscores the importance of imaging, surgical management, and multidisciplinary collaboration. The rare finding of a small bowel angiomyxoma as a lead point emphasises the diverse aetiology of this condition.

The management of colo-colic intussusception on left colon tumor in an adult: Case presentation and review of the literature

INTRODUCTION AND IMPORTANCE

Intestinal intussusception is rare in adults and often associated with underlying malignancies. In this case, a colo-colic intussusception involving the descending colon caused acute obstruction, ischemic pain, and carried a high risk for peritonitis, necessitating urgent surgical intervention to prevent severe complications.

CASE PRESENTATION

We report the case of a 50-year-old male who presented with acute abdominal obtruction and a three-day history of fecal vomiting, left-sided abdominal pain, and recent rectal bleeding. Imaging revealed colo-colic intussusception of the descending colon due to a colonic tumor. Immediate surgical intervention was performed with an oncologic resection of the invaginated segment, including a left hemicolectomy with lymph node dissection. A diversionary left iliac colostomy was conducted, ensuring clear resection margins and reducing the risk of postoperative complications.

CLINICAL DISCUSSION

Intussusception in adults, while rare, frequently indicates a malignant etiology, and prompt diagnosis and management are essential. In this case, rapid surgical intervention allowed successful removal of the tumor with favorable oncologic outcomes and no recurrence at two-year follow-up. This case highlights the complexity of diagnosing intussusception in adults, where symptoms may mimic other gastrointestinal conditions and are often nonspecific.

CONCLUSION

This case underscores the critical importance of early detection and intervention for intussusception in adults. Awareness among physicians should be heightened to consider intussusception in adult patients presenting with symptoms such as ischemic pain or a palpable mass with associated pain, as timely intervention can lead to improved outcomes and reduce morbidity.

Malignancy predictors and treatment strategies for adult intestinal intussusception

Intussusception in adult patients is a rare medical finding, which is accompanied by an underlying tumor in some cases. However, no accepted method has been established to identify patients at risk for tumor-related intussusception. This study aimed to identify imaging features as predictors for tumor-related intussusception.CT images of patients with confirmed intussusception were retrospectively acquired between 01/2008 and 12/2022. Available follow-up images and medical health records were evaluated to identify various imaging features, the cause of intussusception, and treatment strategies. Imaging interpretation was conducted by two blinded radiologists. A third radiologist was consulted in cases of disagreement.A total of 71 consecutive patients were included in this study (42 males, 29 females) with a median age of 56 years (interquartile range: 40.5-73.8 years). Enteroenteric intussusceptions in the small bowel were the most common type observed in adult patients. In contrast, colocolic intussusception was more frequently associated with malignancy, and this association was statistically significant (p < 0.05). Among the malignant tumors, adenocarcinoma was the most common, followed by metastases and lymphoma. Additionally, bowel obstruction and wall thickening were significantly correlated with malignancy (p < 0.05). The high negative predictive values (NPVs) and high specificities for ileus (NPV 88.5%, specificity 82.1%), bowel wall thickening (NPV 90.9%, specificity 71.4%), and acute abdomen (NPV 84.6%, specificity 78.8%) suggest that the absence of these features strongly predicts a low probability of malignancy in cases of adult intussusception.Active surveillance with follow-up exams is suitable for asymptomatic and transient intussusception when imaging features suggest a low likelihood of a neoplasm. Additionally, malignancy predictors such as ileus and thickening of the bowel wall in the affected segment could guide tailored treatment. Surgical interventions are essential for symptomatic cases, with adenocarcinoma being the most common malignancy found in colocolic intussusceptions.Intussusception in adults is rare and is often associated with underlying tumors, particularly in colocolic intussusceptions. Key imaging predictors for malignancy include bowel obstruction, wall thickening in the affected segment, and the presence of acute abdomen, with high NPVs and specificities indicating low malignancy risk when these features are absent. Active surveillance is recommended for asymptomatic cases with low neoplasm probability, while surgical intervention is the method of choice for symptomatic patients. · Reschke P, Le Hong QA, Gruenewald LD et al.

Adult ileo-ileal intussusception caused by inflammatory fibroid polyp leading to small bowel obstruction: a case report with comprehensive literature review

Ileo-ileal intussusception, an infrequent cause of small bowel obstruction in adults, can be initiated by inflammatory fibroid polyps. These are uncommon, benign submucosal lesions of the gastrointestinal tract. This case report explores an adult patient with inflammatory fibroid polyps-induced ileo-ileal intussusception.

Novel laparo-endoscopic hybrid technique of management of a rare case of duodeno-duodenal intussusception

ABSTRACT

We herein report a rare case of duodeno-duodenal intussusception (IS) presenting with obstruction caused by tubulovillous adenoma in an adult with malrotation that was managed by a novel laparoendoscopic hybrid technique. This was done by passing transjejunal nasogastric tube (NG) through one of the ports and manoeuvring it towards the IS. Two hundred and fifty millilitre of saline was flushed by aseptosyringe with pressure connected to the NG. This hydrostatic reduction technique resulted in distension of the jejunal and duodenal loop achieving reduction of IS. Intraoperative endoscopy was performed to exactly localise the mass lesion. The duodenum was kocherised and was delivered through a 4-cm transverse incision. Anterior duodenotomy was performed; the mass was excised; and duodenotomy was closed transversely. An extensive literature search did not show any case report of duodenoduodenal IS being managed by this technique. The combination of novel retrograde decompression and intraoperative endoscopy helped us to manage this rare case by this novel technique.

Small bowel intussusception - aetiology & management

PURPOSE OF REVIEW

Adult small bowel intussusception (SBI) differs in incidence, symptomatology and management from the more commonly encountered paediatric intussusception. This review spans across the multitude of causes of adult SBI, and summarises the diagnostic work-up and management options according to recent literature.

RECENT FINDINGS

There has been an increase in use of small bowel capsule endoscopy and point-of-care ultrasound for the diagnosis of acute adult SBI.

SUMMARY

A high degree of suspicion of a malignant cause of SBI is required in the adult population. Alarm clinical features include weight loss, history of malignancy, and iron deficiency anaemia. CT remains the gold standard imaging technique as it may identify the lead point and thus aid in endoscopic or surgical management. If malignancy is excluded and no lead point is identified, serology and histology may be helpful to look for inflammatory, infective and autoimmune aetiology.

Adult Ileocolic Intussusception Following Appendectomy: A Case Report of a Rare Sonographic Finding

Adult intussusception is a rare condition characterized by the telescoping of one segment of the intestine into an adjacent segment. Prompt recognition and intervention are crucial due to the potential for serious complications. The present case is of adult ileocolic intussusception in a 47-year-old male patient who underwent appendectomy three weeks prior. The patient presented with constipation, lower abdominal pain, and vomiting. A transabdominal ultrasound revealed characteristic sonographic features, including a target appearance at the transverse view and the pseudokidney sign of the longitudinal view associated with the presence of reactive lymph nodes. Doppler ultrasound indicated no internal flow, suggesting possible ischemia. This case highlights the role of ultrasound in the initial evaluation of adult intussusception and emphasizes the need for further imaging modalities for detailed anatomical evaluation and lesion identification.

Intussusception in Incisional Hernia: A Case Report and Literature Review

Intussusception in adults is a rare condition. Most frequently, intussusception involves the small intestine and, very rarely, the large intestine. In this report, we present the case of a 79-year-old male who was admitted with symptoms and signs of bowel obstruction due to an incarcerated incisional hernia (a tender irreducible incisional hernia associated with nausea and vomiting). His CT scan confirmed intussusception in his incisional hernia, showing the target sign. An emergency laparotomy, small bowel resection, and anastomosis were done. The histopathology report revealed the cause of intussusception to be a polypoid small bowel B cell lymphoma. It is necessary to excise the affected bowel segment in order to treat adult intussusception because it is commonly associated with malignant organic lesions. Computed tomography is the most sensitive imaging modality for intussusception; thus, we must consider a low threshold for a scan for patients presenting with abdominal pain.

A Rare Case of Small Bowel Intussusception in an Elderly: A Case Report and Literature Review

Intussusception, a rare cause of bowel obstruction in adults, is even less common in the elderly population. Unlike pediatric cases, adult intussusception is primarily associated with pathologic diseases acting as lead points, often requiring surgical intervention. We present a case of an 84-year-old male with a medical history significant for multiple comorbidities, who was diagnosed with a large segment jejunojejunal intussusception resulting in small bowel obstruction. Surgical management was recommended, and an exploratory laparotomy with bowel resection was performed, including the excision of the leading point. This case highlights the challenges in diagnosing adult intussusception and the importance of surgical intervention due to the high incidence of associated pathologic diseases.

Intestinal intussusception in adults: Location, causes, symptoms, and therapeutic management

OBJECTIVE

Intestinal intussusception is difficult to diagnose in adults because the symptoms are nonspecific. However, most have structural causes that require surgical treatment. This paper reviews the epidemiologic characteristics, imaging findings, and therapeutic management of intussusception in adults.

MATERIALS AND METHODS

This retrospective study identified patients diagnosed with intestinal intussusception who required admission to our hospital between 2016 and 2020. Of the 73 cases identified, 6 were excluded due to coding errors and 46 were excluded because the patients were aged <16 years. Thus, 21 cases in adults (mean age, 57 years) were analyzed.

RESULTS

The most common clinical manifestation was abdominal pain, reported in 8 (38%) cases. In CT studies, the target sign yielded 100% sensitivity. The most common site of intussusception was the ileocecal region, reported in 8 (38%) patients. A structural cause was identified in 18 (85.7%) patients, and 17 (81%) patients required surgery. The pathology findings were concordant with the CT findings in 94.1% of cases; tumours were the most frequent cause (6 (35.3%) benign and 9 (64.7%) malignant).

CONCLUSIONS

CT is the first-choice test for the diagnosis of intussusception and plays a crucial role in determining its aetiology and therapeutic management.

An ileo-colic intussusception reaching down to the descending colon - A case report

Introduction and importance

Intussusception in healthy adults is rare and often associated with oncologic diseases. This case report presents a case of an ileo-colic intussusception reaching down to the descending colon in a healthy adult that required ileo-colic resection.

Case presentation

We present a case of a 78-year-old male patient with acute onset unspecific abdominal pain. The medical history was unremarkable. Preoperative radiologic assessments showed an invagination of the small intestine into the colon without any signs of polyps or tumours. An emergency laparotomy with resection of the affected intestine was performed. The pathologist described a 49 cm length of intussuscepted colon and an additional 7 cm intussusception of the terminal ileum. A circular area with multiple polyps extending over 8 cm in the colon could be identified. The microscopic findings showed a low-grade dysplasia within this area. Following surgery, the patient was discharged to rehabilitation after a ten-day hospitalization.

Clinical discussion

Intussusception in adults is rare and the clinical presentation includes unspecific symptoms making the diagnosis challenging. In 90% of the cases, a pathologic lesion is found (two-thirds are neoplasms). An intussusception involving the colon should be treated surgically without prior reduction due to the high incidence of a neoplasm and the risk for perforation and tumour dissemination.

Conclusion

In the literature, neoplastic disease represents the major cause for intussusception in adults. This report presents a rare case of an ileo-colic intussusception reaching down to the descending colon treated successfully with a subtotal colectomy.

•

Intussusception is a differential diagnosis in adults with abdominal pain.

•

In up to 90% of the cases, an underlying disease or condition can be identified.

•

Increasing incidental diagnosis due to better quality and availability of CT scan.

•

If the colon is involved, the best treatment is surgical without prior reduction.

A Rare Case of Colo-Colonic Intussusception Caused by Colonic Submucosal Lipoma

Unlike in infancy, where intussusception is an abdominal emergency, diagnosis of intussusception could be tricky in adults as most of these patients present sub-acutely with vague abdominal symptoms. Early diagnosis could impact these patients significantly in decreasing morbidity and mortality along with reduction in healthcare expenses. Colo-colonic intussusception is rare and accounts for less than 20% of adult intussusception. More than 50% of adult intussusception is caused by mass-like lesions. In such cases, this could be an early presentation of malignant intestinal lesions. Abdominal CT is mandatory in all adult patients; when combined with ultrasound, it has 95.5% accuracy of pre-operative diagnosis. Here we report a case of a 42-year-old female who presented with a two-month history of intermittent abdominal pain; a CT abdomen revealed colo-colonic intussusception which was initially missed on prior imaging. We discuss the importance of considering intussusception as a rare differential of abdominal pain, the need for early diagnosis, and the role of colonoscopy and non-surgical management in adults.

Intestinal intussusception caused by intestinal duplication and ectopic pancreas: A case report and review of literature

BACKGROUND

Intestinal intussusception caused by intestinal duplication and ectopic pancreas is extremely rare in the clinic and has not been reported previously.

CASE SUMMARY

A 29-year-old man was admitted to the hospital for chronic abdominal pain and bloating. The preoperative diagnosis was intestinal obstruction and intussusception. Then, laparotomy, partial small intestinal resection and extraintestinal decompression were performed. Postoperative pathology confirmed intestinal duplication and ectopic pancreas. After surgery, the patient recovered well with no complications. No recurrence was observed after more than 5 mo of follow-up.

CONCLUSION

We report a new case of a young male with intussusception caused by intestinal duplication and ectopic pancreas. Surgery is the main treatment for these conditions. This study aimed to raise awareness and provide information to improve the clinical management of this rare yet serious condition.

Colonic Lipoma as a Leading Cause of Intussusception Resulting in Bowel Obstruction

A colon lipoma is defined as a benign tumor made of adipose tissue present in the submucosa. Lipomas of the colon are unusual with a frequency of 0.035%-4.4%. We present an uncommon case of a 41-year-old female with left colonic lipoma causing intussusception. The patient presented with abdominal pain at the left iliac fossa. She underwent an emergency exploratory laparotomy plus left hemicolectomy and was followed in the surgical out-patient clinic postoperatively. She was found doing well taking a normal diet and having normal bowel habits. The overall prognosis depends on the complete removal of the tumor.

Recurrent Right Upper Quadrant Pain Masquerading an Underlying Colon Adenocarcinoma-Induced Intussusception

Intussusception in adults is a challenging diagnosis that often requires a high degree of suspicion. In adults presenting with symptoms, almost 90% have underlying neoplasms. Most frequently, the presentation will include nonspecific abdominal pain, vomiting, and mucoid hematochezia. In this case, we present a 39-year-old female with a rare presentation of chronic, recurrent right upper quadrant abdominal pain over a 5-month interval. The misleading presentation with which the patient presented led to a delay in diagnosis and treatment of colon malignancy and serves to advocate for intussusception as a differential for adult patients presenting with obstructive symptoms of unknown origin and recurrent abdominal pain. Such cases should persuade physicians to plan prompt surgical intervention as to not delay optimal diagnostic and therapeutic outcomes.

Intestinal intussusception in adults: location, causes, symptoms, and therapeutic management

OBJECTIVE

Intestinal intussusception is difficult to diagnose in adults because the symptoms are nonspecific. However, most have structural causes that require surgical treatment. This paper reviews the epidemiologic characteristics, imaging findings, and therapeutic management of intussusception in adults.

MATERIALS AND METHODS

This retrospective study identified patients diagnosed with intestinal intussusception who required admission to our hospital between 2016 and 2020. Of the 73 cases identified, 6 were excluded due to coding errors and 46 were excluded because the patients were aged<16 years. Thus, 21 cases in adults (mean age, 57 y) were analyzed.

RESULTS

The most common clinical manifestation was abdominal pain, reported in 8 (38%) cases. In CT studies, the target sign yielded 100% sensitivity. The most common site of intussusception was the ileocecal region, reported in 8 (38%) patients. A structural cause was identified in 18 (85.7%) patients, and 17 (81%) patients required surgery. The pathology findings were concordant with the CT findings in 94.1% of cases; tumors were the most frequent cause (6 (35.3%) benign and 9 (64.7%) malignant).

CONCLUSIONS

CT is the first-choice test for the diagnosis of intussusception and plays a crucial role in determining its etiology and therapeutic management.

Jejunojejunal intussusception in an adult: a rare presentation of abdominal pain in the emergency department

Abdominal pain is a common presentation to the emergency department (ED) and the differential diagnoses is broad. Intussusception is more common in children, with only 5% of cases reported in adults. 80%-90% of adult intussusception is due to a well-defined lesion resulting in a lead point, whereas in children, most cases are idiopathic. The most common site of involvement in adults is the small bowel. Treatment in adults is generally operative management whereas in children, a more conservative approach is taken with non-operative reduction. We present a case of a 54-year-old woman who presented to our ED with severe abdominal pain and vomiting. CT of the abdomen revealed a jejunojejunal intussusception. The patient had an urgent laparoscopy and small bowel resection of the intussusception segment was performed. Histopathological examination of the resected specimen found no pathologic lead point and, therefore, the intussusception was determined to be idiopathic.

Differentiation Between Surgical and Nonsurgical Intussusception: A Diagnostic Model Using Multi-Detector Computed Tomography

Background:

The differentiation of surgical from nonsurgical adult intussusception may enable the appropriate selection of management strategies.

Objective:

This study aimed to investigate the diagnostic potential of multidetector computed tomography (MCDT) features to differentiate surgical from nonsurgical adult intussusception and develop a diagnostic model.

Methods:

A retrospective study was performed on 96 patients with intussusceptions at the University Medical Center Hospital between January 2014 and January 2020. Two radiologists reviewed all images, and intussusception characteristics were documented. The location of intussusception, length, diameter, interposed fat thickness, lead point, and complications were evaluated. Based on the results, a diagnostic tree model was developed to differentiate between surgical and nonsurgical adult intussusception.

Results:

A total of 99 intussusceptions in 96 patients (mean age: 53.0 ± 16.5 years), including 35 (35.3%) enteroenteric, 27 (27.3%) enterocolic, and 37 (37.4%) colocolic lesions, were evaluated. Of the enteroenteric intussusceptions, 22 (62.9%) were surgical, including 19 (79.2%) with lead points. Among colon intussusceptions, 63 (98.4%) were surgical, and 100% had lead points. The characteristics used to predict surgical intussusceptions included lead point presence, length ≥ 5.0 cm, diameter ≥ 3.2 cm, interposed fat thickness ≥ 0.5 cm, and complications (p < 0.001). Based on these features, we established a diagnostic tree model that correctly classified 96 (97%) of 99 lesions.

Conclusion:

Our study reinforces the importance of MDCT for the diagnosis and guided management of adult intussusceptions. The characteristics that predicted surgical intussusceptions included lead points, length, diameter, interposed fat thickness, and complications. A systematic approach using this diagnostic tree model could be used to distinguish surgical and nonsurgical adult intussusception.

Bleeding Edge Therapy: Ileocolic Intussusception Due to Ileocecal Valve Adenocarcinoma and Its Management in an Adult Patient-Case Report and Literature Review

Adenocarcinoma as the primary cause of bowel intussusception is uncommon. We describe the case of a 86-year-old patient admitted for ileocecal intussusception due to the presence of adenocarcinoma, located in the ileocecal valve and right colon. The etiologies of intussusception, its diagnosis, and conservative or surgical treatments are discussed, with attention placed on the indications for reduction of the invagination prior to surgical resection.

Epidemiology of intussusception among children less than 2 years of age; findings from baseline surveillance before rotavirus vaccine introduction in Myanmar

BACKGROUND

Rotavirus vaccine was planned to be introduced in the National Immunization Program of Myanmar in 2020. Reported potential association of a small increased risk of intussusception after rotavirus vaccination in some countries is a major safety concern and it is mandatory to collect baseline information before vaccine introduction.

METHODS

Retrospective study reviewed medical records of intussusception cases for past 3 years (2015-2018) and prospective, active study was conducted from August 2018 to January 2020 at three tertiary children hospitals where pediatric surgical facility is present. Brighton Level 1 Criteria was used for confirmation of intussusception among children <2 years of age admitted to surgical wards. Demographic, clinical, diagnostic and treatment practices data were collected and descriptive data analysis was performed.

RESULTS

A total of 697 (421 in retrospective and 276 in prospective) confirmed intussusception cases were identified. Majority of intussusception cases (550/697, 78.9%) were observed in the first year of life and most frequent between 5-7 months of age (292/697, 41.9%) with a peak at 6 months (114/697, 16.4%). The most common clinical presentations were vomiting and bloody diarrhea accounting 82.1% and 77.5% respectively. Regarding diagnosis and treatment, 458/697 (65.7%) required surgical intervention either manual reduction or intestinal resection and 34.4% by either air or barium enema. Overall mortality was 0.7% (5/697) and four out of five children died needed intestinal resection. Late arrival to hospital (>3days after onset) is significantly associated with requirement of surgery (61/85, 71.8%), which in turn is significantly associated with longer hospital stay (296/452, 65.5%) (p < 0.05).

CONCLUSIONS

Intussusception occurrence is most frequent between 5-7 months age group which is old enough to be vaccinated under the schedule that has now been introduced in Myanmar. More than half of the cases were treated by surgery and late arrival to hospital enhances requirement of surgery and poor outcome. Findings of this baseline surveillance provide important facts for public health officials in balancing risks and benefits of rotavirus vaccine introduction, defining targeted age and dosage scheduling and facilitate monitoring system in post-vaccination.

Pedunculated Lipoma of the Caecum Causing Colocolic Intussusception in an Adult

Introduction

Colocolic intussusception in adults is uncommon and poses both a diagnostic and therapeutic dilemma. The association of an underlying malignancy necessitates a preoperative confirmation of diagnosis. The presenting features are variable. Hence contrast enhanced computed tomography of the abdomen is pivotal for diagnosis. An en bloc resection of the specimen in accordance with standard oncological principles is the mainstay of treatment.

Case report

A case of colocolic intussusception in an adult is presented to highlight the difficulties in preoperative diagnosis and in selecting the best surgical option for treatment.

Conclusion

Adult bowel intussusception is a diagnostic dilemma with preoperative diagnosis being the biggest challenge. CT scan of the abdomen is an excellent diagnostic modality with high diagnostic accuracy. Explorative laparotomy with en bloc resection is mainstay of treatment in adults.

Successful laparoscopic approach for idiopathic adult colo-colonic intussusception: a case report

Background

Adult intussusception is recognized as an abdominal emergency. More than 90% of adult patients with intussusception have distinct causes that are related to benign or malignant tumors. In contrast, idiopathic intussusceptions, which are observed in children, are rare conditions in adult. Especially, colo-colonic idiopathic intussusceptions are rare among them. Surgery is traditionally considered the primary treatment option. Recently, laparoscopic surgery has been reported to be safe and feasible. However, laparoscopic surgical reduction, which is a common procedure in pediatric surgery, is not common in adult intussusception.

Case presentation

We report a 34-year-old man who presented with sudden abdominal pain. Computed tomography revealed the target sign in the transverse colon. There was no evidence of bowel obstruction, bowel wall edema, or tumor. We diagnosed idiopathic intussusception and selected laparoscopic procedure because of the strong abdominal pain experienced by the patient. There were no signs of perforation, bowel wall ischemia, or tumor in abdominal cavity. We confirmed idiopathic colo-colonic anterograde intussusception. Laparoscopic surgical reduction was achieved by a combination of delicate direct pressure on the anal side of the transverse colon and gentle pulling on the oral side. The patient’s postoperative course was uneventful.

Conclusions

We achieved successful surgical reduction laparoscopically because of an accurate preoperative diagnosis based on characteristic computed tomography features and appropriate surgical technique. Laparoscopic procedure and surgical reduction is considered to be an effective treatment strategy for adult idiopathic intussusceptions with severe symptoms.

Most Adult Intussusceptions are Caused by Tumors: A Single-Centre Analysis

Background

Adult intussusception is less common than paediatric intussusception. The aim of this study was to explore the clinical presentation, aetiology, diagnosis and treatment of adult intussusception.

Methods

Adults (>18 years) with intussusception treated by surgical or conservative measures were included from January 2005 to January 2018, and the manifestation, types, diagnosis and treatment of adult intussusception in our centre were reviewed.

Results

A total of 150 patients with adult intussusception were included in this study. The clinical manifestations included 111 cases (74%) of abdominal pain, 38 cases (25.3%) of bloody stool, 37 cases (24.7%) of bowel obstructions, 33 cases (22%) of abdominal distension, 29 cases (19.3%) of nausea and vomiting, 19 cases (12.7%) of an abdominal mass, and 12 cases (8.0%) of diarrhoea. The types of intussusception were classified into 36 cases (24%) of enteric intussusception, 87 cases (58%) of intestine-colon intussusception and 27 cases (18%) of colonic intussusception. Surgical intervention was applied in 139 cases (92.7%), including 115 patients who underwent open surgery, and laparoscopy-assisted surgery was performed in 24 patients. The main pathogenesis of intussusception was malignant tumors in 51 cases (36.7%) and benign tumors and polyps in 49 cases (35.3%).

Conclusion

Malignant and benign tumors are the main causes of adult intussusception. Abdominal CT is the preferred evaluation method for the preoperative diagnosis of this condition. The choice of surgical procedure depends on the location and type of intussusception.

Jejunal Intussusception in Adolescent Crohn's Disease: An Extremely Rare Complication

Proximal small bowel intussusception occurring in an adolescent Crohn's disease patient is an extremely rare entity. It is usually primary without a lead point and quite often a transient phenomenon. We report such transient and intermittent jejunal intussusception in a 16-year-old male, developing immediately in a postoperative period after a stoma reversal for jejunal stricture perforation peritonitis.

•

Intussusception is a rare cause of postoperative small bowel obstruction in adult and the treatment is still debated.

•

Bowel Intussusception should be kept in mind in a post operative patient who develops obstructive symptoms.

•

The time of diagnosis makes the difference between surgical treatment and others.

Abdominal CT have a good accuracy in diagnosis.

•

Surgery is necessary if peritoneal irritation is present. Otherwise, conservative treatment is considered.

Introduction

Postoperative intussusception is a rare cause of intestinal obstruction in adults. Intussusception refers to a condition in which a segment of the intestine invaginates into the lumen of an adjacent segment of the intestine.

Presentation of case

We report a case of postoperative jejunojejunal intussusception in a 42-year-old male following a laparoscopic low anterior resection for rectal cancer. In post-operative day (POD) 2 the patient showed intermittent bowel obstruction and fever. Diagnosis was established with abdominal computed tomography (CT) and enteroclysis, which led to a spontaneous reduction of the invagination.

Discussion

The incidence of intussusception in adults is rare condition. It represents less than 5% of all cases. In adults, transient asymptomatic enteric intussusception often resolves spontaneously without any treatment. When bowel obstruction is complete and persistent, surgery is need. Intussusception as cause of intestinal obstruction should be kept in mind in a post operative patient who develops obstructive symptoms. Early diagnosis makes the difference between surgical and others treatment. The pathogenesis and diagnosis of postoperative intussusception in the adult is discussed in the case report.

Conclusion

The authors presented a rare cause of postoperative small bowel obstruction treated without surgery. The peculiarity of this case report is that the authors have successfully used, in an adult, conservative treatment with gastrografin, which is the treatment of choice used in children. The use of gastrografin was decisive and there were no recurrences in the follow up.

An uncommon diagnosis of a common presentation of mass per rectum

Introduction - In adults, protrusion of intussuscepted sigmoid growth through the anal canal is exceedingly rare, with only 9 cases being reported till date. Case Report - A 52-year old man presented to emergency department with what appeared to be an episode of rectal prolapse following straining while defaecating. On examination, he had a prolapsed 8 × 8 cm bowel, with a 2 × 2 cm friable villous growth as the lead point, with space between the mass and the perianal skin. Computed Tomography of the abdomen was done which was suggestive of telescoping of the sigmoid into the rectum protruding out through the anal canal with features of intestinal obstruction. He underwent exploratory laparotomy with sigmoidectomy with Hartman's Procedure. Post-operative period was uneventful. Histopathology was suggestive of moderately differentiated carcinoma. Discussion - In colo-anal intussusception, as was in our patient, the preferred approach is to reduce the intussusception before resection, to perform a sphincter saving operation as compared to an Abdominoperineal Resection (APR) otherwise. Conclusion -A high index of suspicion is important to diagnose and treat such cases early to avoid lethal outcomes by misdiagnosing it as simple rectal prolapse.

Use of Ultrasound in the Diagnostic Work-Up of Adult Intussusception - A Multicenter Retrospective Analysis

PURPOSE

 To evaluate the use of ultrasound (US) in the diagnostic work-up of adult intussusception (AI).

METHODS

 This multicenter study includes 26 consecutive patients diagnosed with AI between January 2010 and November 2017. A retrospective chart analysis was conducted with a focus on abdominal US findings and diagnostic accuracy of different imaging modalities (ultrasound, computed tomography (CT), magnetic resonance imaging). If available, surgical and pathological findings served as the gold standard (76.9 %). US examiners certified according to DEGUM grade 2 or 3 were classified as experts. Otherwise, they were regarded to have basic skills.

RESULTS

 During diagnostic work-up, 92.3 % underwent abdominal US. US was the first-line imaging modality in 88.5 % of cases. The accuracy regarding the detection of AI (85 %), correct localization (95 %) and detection of complications (100 %) was excellent and comparable with CT (81 %, 90.5 %, and 91.7 %) when performed by experts. 72.7 % of tumorous lead points were detected by experienced examiners. In contrast, AI was detected in only 45.5 % of cases by examiners with basic skills. AI was diagnosed prior to surgery in all patients.

CONCLUSION

 US is reliable in the diagnostic work-up of AI when performed by experienced examiners with high-quality equipment. US, CT and MRI should be used in a complementary fashion since combination provides excellent sensitivity regarding the detection and correct localization of AI as well as the detection of complications. The impact of real-time imaging is illustrated by supplementary videos.

Ileocolic intussusception caused by ileal lipoma: A case report

RATIONALE

Adult intussusception is rarely observed, accounting for about 5% of all cases of intussusception. Most ileal lipomas are asymptomatic and do not need any special treatment. Herein, we describe a case with ileocolic intussusception caused by ileal lipoma.

PATIENT CONCERNS

A 27-year-old woman complaints of intermittent abdominal pain for 10 days.

DIAGNOSIS

Abdominal computed tomography demonstrated ileocolic intussusception. Colonoscopy revealed a spherical polypoid lesion with surface capillary rising from the lateral wall of the ileum. A diagnosis of ileocolic intussusception was made.

INTERVENTIONS

The patient underwent primary resection of the intussuscepted intestine after which an end-to-end anastomosis was performed.

OUTCOMES

Histopathology report confirmed a 4.5 cm × 3.5 cm lipoma in the terminal ileum. The patient was discharged on a postoperative day 9 without complications.

LESSONS

We describe the difficulties in diagnosis and treatment of this rare cause of intussusception and review the literature on adult intussusceptions. The ileal lipoma is a very rare cause of ileocolic intussusception. Abdominal CT and colonoscopy are important for the diagnosis of intussusception and abdominal lipomas. Surgical resection remains the treatment of choice.

Small Bowel Obstruction Secondary to Intussuscepted Meckel's Diverticulum in an Adult

Intussusception secondary to inverted Meckel's diverticulum resulting in intestinal obstruction is rare. The following is a case report that discusses a 29-year-old female who posed diagnostic uncertainty for the treating surgical team and ultimately underwent emergency surgery for the management of intestinal obstruction. Small bowel intussusception was diagnosed preoperatively on abdominal computer tomography (CT). At operation, it was found to be secondary to inverted Meckel's diverticulum with histopathology confirming the diagnosis.

Diagnostic challenge of the non-specific presentation of adult intussusception

The following report will discuss the diagnosis and management of non-specific abdominal pain in a 77-year-old woman who presented to a district general hospital in South London. CT imaging demonstrated ileo-colic intussusception with free air and fluid indicating perforation. The images of the specimen clearly show the ileal tumour within the intussusception. Thus, the patient underwent an emergency right hemicolectomy and formation of a double-barrelled ileostomy. Histology subsequently confirmed this was secondary to a colonic adenocarcinoma. This case report is unique as it highlights that intussusception in adults is very difficult to accurately diagnose based on clinical features (due to non-specific findings) and even with radiology can be challenging. This is also the first documented case of the site of perforation not being directly involved with the site of intussusception. The perforation site was in fact distal to the intussusception. At the time of surgery, it was noted that the patient had significantly faecal loading up to her rectum. The resulting closed loop was the cause of her perforation.

Tube feeding associated postoperative intussusceptions: A single center case series study

RATIONALE

Postoperative intussusception in adults is a rare but serious complication after gastrointestinal anastomosis surgery. Postoperative intussusception in adults caused by tube feeding was rarely been reported before. The aim of the current study was to summarize the clinical data on a group of patients with tube feeding associated postoperative intussusceptions. The possible etiology and preventive measures will also be discussed.

PATIENT CONCERNS

During the period from May 2013 to January 2018, patients who received gastrointestinal anastomosis in our center were retrospectively reviewed. Preoperative variables including standard demographic and pathological characteristics as well as the treatment and prognosis were also analyzed.

DIAGNOSES

Tube feeding associated postoperative intussusceptions.

INTERVENTIONS

7 patients were identified with tube feeding associated postoperative intussusceptions with a prevalence of 0.38%. Intussusceptions occurred from 10 to 69 days (median 25.7 days) postoperatively in an acute form.

OUTCOMES

None of the patients had spontaneous reduction and all patients underwent surgery. Antegrade efferent limb intussusceptions were found in all the cases. Intussusception occurred at efferent loop at 23.6 cm (range 15-60) from the gastrointestinal or Braun anastomosis. None of the patients was found recurrence throughout the follow-up period.

LESSONS

In contrast with other postoperative intussusceptions, the tube feeding associated postoperative intussusceptions have special clinical manifestations. It is more likely to occur in early period of time after the surgery and in an acute form. Surgical correction is recommended for most of patients. Several measures have been proposed to prevent such complications after gastrointestinal surgery, however more research and information are still needed.

Adverse events in patients with ulcerative colitis treated with indigo naturalis: a Japanese nationwide survey

BACKGROUND

Although indigo naturalis (IN) is effective for patients with active ulcerative colitis (UC), IN was associated with adverse events (AEs), including pulmonary arterial hypertension (PAH). Our aim was to evaluate the occurrence of IN-associated AEs and to evaluate any IN dose-effect on AEs.

METHODS

A nationwide survey, using questionnaires, was conducted by conducted by the research group funded by the Ministry of Health, Labour and Welfare of Japan, between June 2017 and September 2018. A first questionnaire determined the occurrence of AEs associated with the therapeutic use of IN or herbal medicines containing IN in patients with UC. A second survey identified the clinical characteristics of patients who developed IN-associated critical AEs, namely, liver dysfunction, PAH, and intussusception.

RESULTS

Across 337 participating institutions, 49,320 patients with UC were identified, with IN used in 877 (1.8%). AEs were reported in 91 patients (107 events), including liver dysfunction (n = 40), gastrointestinal symptoms (n = 21), headache (n = 13), and PAH (n = 11). No dose-effect relationship between IN and AEs was identified. Liver dysfunction tended to be mild and reversible. Ten cases of intussusception were reported, with 40% of these patients requiring surgical resection. IN-induced PAH was recovered in patients who discontinued to use IN. No IN-associated deaths were reported.

CONCLUSIONS

IN-associated AEs were identified among patients with UC, with liver dysfunction often being reversible, while surgical resection was required in a high proportion of patients who developed intussusception. Both healthcare workers and patients should adequately recognize the potential for AEs with the use of IN.

Sigmoido-rectal intussusception

Rectal prolapse is usually of benign etiology. Rarely, sigmoido-rectal intussusception results from a malignant lead-point. We report the case of a patient with a partially obstructing sigmoid cancer causing a full thickness rectal prolapse requiring surgical intervention. An 82-year-old woman presented with 1 week of rectal bleeding, fecal incontinence, and weight loss. Computed tomography identified sigmoido-rectal intussusception. Colonoscopic biopsy revealed high-grade dysplasia. Magnetic resonance imaging demonstrated a 6-cm mass forming the lead point of the intussusceptum with epiploic appendages seen within the rectal lumen. She underwent laparoscopic low anterior resection with final pathology consistent with T2N0 adenocarcinoma, and recovered well. Among adult patients with rectal prolapse, suspicion for underlying malignancy should prompt a thorough investigation to inform the decision for resection, which may be safely performed by minimally invasive techniques.

Missed case of intussusception, a rare cause of abdominal pain in adults: A case report emphasizing the imaging findings and review of the literature

Intussusception, a process whereby a segment of the intestine telescopes into the adjoining intestinal lumen, is a rare source of pain in adults that present with nonspecific abdominal pain. Imaging is the mainstay for diagnosis, which requires prompt and accurate interpretation to prevent complications. The following report details the misdiagnosis of intussusception in a 54-year-old male, whom presented to the emergency department with a 4-day history of nonrelenting abdominal pain, nausea, vomiting, and constipation. Following blood tests, chest, and abdominal imaging, the patient was discharged with a suspected passed renal stone. He soon represented to the General Practitioner, however, with equivalent pain; prompting a review of the images. It was apparent that the initial radiologist failed to recognize the subtle presence of intussusception. This case highlights the necessary consideration of intussusception as a differential diagnosis in adult patients presenting with intermittent abdominal pain. The case further emphasizes that radiologists should be familiar with the subtler signs of intussusception.

Intussusception Can Be the First Sign of Post-transplant Lymphoproliferative Disease

Intussusception is usually seen in the pediatric age group and rarely seen in adults. It results in the progression of the proximal segment of the intestine into the distal intestine. A 50-year-old immunosuppressive male patient presented with the complaints of abdominal pain, nausea, vomiting, and no gas or stool discharge for 2 days. He was hospitalized with the presumptive diagnosis of acute abdomen. He has a history of renal transplantation due to chronic renal insufficiency. An explorative laparotomy was performed. The operative findings were compatible with jejunojejunal intussusception, and a segmental small bowel resection and end-to-end anastomosis were performed. The patient was uncomplicated postoperatively and discharged on the fifth postoperative day. The pathology was reported as Epstein-Barr virus negative with diffuse large-cell B lymphoma. In this case report, we aim to report on a jejunojejunal intussusception that was presented as the first sign of post-transplant lymphoproliferative disease.

Ileal schwannoma causing intussusception in an adult

Ileal schwannomas are extremely rare tumours. Very few cases have been previously reported. Most cases present with abdominal pain and gastrointestinal bleeding; intussusception is a rare presentation. Due to limitations in imaging modalities, arriving at a diagnosis preoperatively can be challenging. The only reliable method of diagnosis, and treatment, is resection of the tumour, followed by histological and immunohistochemical testing. This report details the rare case of intussusception as the presenting feature of an ileal schwannoma.

Colonic intussusception caused by a sigmoidal lipoma: A case report

•

Intestinal intussusception in adults is rare, accounting for approximately 1% of all bowel obstructions.

•

Colo-colonic intussusception accounts for 17% of cases.

•

The occurrence of large lipomatous masses as cause of intussusception and semi-obstructive symptoms remains rare.

•

The case that we describe is particularly unique because apart from being an example of intussusception in adults, it occurred in the sigmoid colon and was not associated with a malignant lesion.

Introduction

Intussusception is a relatively common condition seen in children. In comparison, adult intussusception is rare and is often secondary to inflammatory diseases, benign or malignant tumors and motility disorders. Being a benign cause, lipomas appear as a particularly rare gastrointestinal tumor.

Presentation of Case

We present a case of colo-colonic intussusception secondary to a sigmoidal lipoma, in a 40-year-old man. We describe the different aspects of diagnosis and management of this rare complication.

Discussion

Adult intussusception is the cause of symptomatic bowel obstruction in 1% of cases and its colo-colonic occurrence represents 17% of all intestinal intussusceptions. The case that we describe is particularly unique because apart from being an example of intussusception in adults, it occurred in the sigmoid colon and was not associated with a malignant lesion. The treatment of intussusception in adults is surgical resection because of the high incidence of underlying malignancy. Colonoscopy is a modality which allows direct visualization of the lipoma. However, intraluminal reduction via colonoscopy is not recommended.

Conclusion

Colo-colonic intussusception is a very rare complication of lipoma. It is determined that the treatment is surgical due to the risk of malignancy.

Telescoping jejunum: a case of adult intussusception

Intussusception is the invagination of a proximal part of intestine into the adjacent distal part. Reported frequently in children, it forms a rare presentation in adults and can be difficult to diagnose pre operatively. Imaging modalities are increasingly being used for preoperative diagnosis with almost all cases in adults being secondary to an intestinal lesion. Intraoperative management of such lesions in adults was mostly reported to be done by en bloc resection without attempts at reduction, especially where a preoperative diagnosis of a benign lesion was not in hand. We present a case of a female patient with a background of active metastatic lung cancer presenting with symptoms and signs of high intestinal obstruction, found to have a jejunal intussusception on CT scan and managed conservatively initially, followed by definitive surgical management. Literature review of similar presentations, diagnostic and treatment modalities are discussed thereafter.

A Rare Case of Primary Small Bowel Adenocarcinoma with Intussusception

Other than in childhood, intussusception is unusual and nearly always caused by a structural and well demonstrable lesion. In contrast with the colon tract, the incidence of primary malignancies in the small bowel is very low. We report the case of a 51-year-old man presenting with jejunal intussusception due to a primary adenocarcinoma. To our knowledge, only a few similar cases have been reported in the literature to date. The patient was referred to our division for bowel obstruction. A CT scan showed a jejunal intussusception and surgical exploration was hence considered. At laparotomy, jejunal intussusception located just after the ligament of Treitz due to a polypoid lesion was confirmed and resection of the first jejunal loop was carried out. Histological examination of the specimen resulted in a diagnosis of a primary adenocarcinoma of the small bowel. In adult intestinal intussusception, resection without reduction is considered the optimal management if an underlying primary malignancy cannot be excluded.

A Case of Jejunal Intussusception caused by Burkitt Lymphoma in an Acquired Immunodeficiency Syndrome Patient

Non-Hodgkin's lymphoma of B-cell type is the second most common neoplasm after Kaposi's sarcoma among patients with human immunodeficiency virus infection. Most non-Hodgkin's lymphoma cases that are associated with acquired immunodeficiency syndrome (AIDS) involve extranodal sites, especially the digestive tract and the central nervous system. We report a case of multiple jejunal intussusception caused by Burkitt lymphoma in a 42-year-old AIDS patient. Upper gastrointestinal endoscopy and surgical biopsy were performed and a complete diagnostic study including histological and immunohistochemical analyses showed Burkitt lymphoma.
