Total colorectal and terminal ileal duplication presenting as intussusception and intestinal obstruction

Colonic intussusception and gastrointestinal duplication are diseases that arise in young children. The clinical presentation of adult cases of intussusception and enteric duplication is non-specific and thus poses a diagnostic challenge. A computed tomography (CT) scan is recommended in adult cases as the most sensitive diagnostic tool and the pathognomonic finding of outer intussuscepiens and central intussusceptum is diagnostic. A septum of a duplicated colon in a non-intussuscepted segment has been rarely reported in the literature. With advancements in radiological imaging technology and the increased availability of CT scanners, the capacity for a correct pre-operative diagnosis has been significantly enhanced. Our current case report illustrates the importance of considering an uncommon etiology for enteric intussusception and duplication as a differential diagnosis of acute abdomen in an adult patient. Our analyses of this patient also highlight the successful use of CT scanning to make this diagnosis.

Pneumatosis intestinalis with obstructing intussusception:A case report and literature review

Pneumatosis intestinalis(PI) often represents a benign condition that should not be considered as an argument for surgery. We report a patient with PI and obstructing intussusception who underwent urgent colectomy and review the literatures regarding PI with intussusception. A 20-year-old man presented at our hospital with a 3-d intermittent lower abdominal pain history. He underwent steroid therapy for membranoproliferative glomerulonephritis for 4 years. Computed tomography revealed ascending colon intussusception with air within the wall. Intraoperative colonoscopy revealed numerous soft polypoid masses with normal overlying mucosa and right hemicolectomy was performed. Histological examination of colonic wall sections revealed large cysts in the submucosal layer. The pathological diagnosis was PI. Nine cases of intussusception associated with primary PI have been reported. Although primary PI often represents a benign condition that should not be considered as an argument for surgery,if the case involves intussusception and obstruction,emergent laparotomy should be considered.

Enteric duplication cyst as a leading point for ileoileal intussusception in an adult:A rare cause of complete small intestinal obstruction

Duplication of alimentary tract(DAT) presenting as an ileoileal intussusception is a very rare clinical entity.Herein,a case of an ileoileal intussusception due to DAT is presented.A 32-year-old woman was hospitalized due to diffuse,intermittent abdominal pain,vomiting and constipation for 3 d associated with abdominal distention.Plain abdominal X-ray revealed dilated small bowel.Abdominal computed tomography showed grossly dilated small bowel with "sausage" and "doughnut" signs of small bowel intussusception.She underwent laparotomy,with findings of ileoileal intussusception due to a cystic lesion adjacent to the mesenteric side.Resection of the cystic lesion along with the affected segment of intestine,with an end to end anastomosis was performed.The histopathology was consistent with enteric duplication cyst.This case highlights the DAT,although,an uncommon cause of adult ileoileal intussusception should be considered in the differential diagnosis of intussusception in adults,particularly when the leading point is a cystic lesion.

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.

Intestinal Invagination in Adults: About a Case at the “Mother-Child” Hospital Le Luxembourg in Mali

Intussusception is a pathology of infants and young children. Its occurrence in adults is very unusual. In the vast majority of cases, it is secondary to a benign or malignant tumor. Small bowel malignancies are relatively rare, 1% - 5% of malignant tumors of the gastrointestinal tract. Acute intussusception, a rare pathology in adults, often presents with non-specific symptoms. Contrary to children, the organic origin remains preponderant in the elderly, where the origin of neoplasia must be suspected in first intention. We report the case of a 49-year-old patient admitted urgently from the Luxembourg “Mère Enfant” hospital center in Bamako, Mali, for an occlusive syndrome. Several abdomino-pelvic ultrasounds were performed in several clinics with mixed conclusions: Hydro-aeric distension and a cessation of matter and gas without a clearly visible mass (04/09/2022);Demonstration of the central hydro-aeric levels wider than high containing fine and regular folds corresponding to connivents whose aspect is in factor of left acute small intestine occlusion, to be completed by the surgical opinion (06/09/2022) and a third ultrasound showed a normal appearance of the liver, gallbladder, kidneys, pancreas, spleen, bladder and prostate;diffuse aero-colic distention without lesion of secondary appearance (21/11/2022). A frontal standing ASP dated 11/25/2022 showed hail-like hydro-aeric levels. Surgical management consisted of an open oncological resection of an obstructive bowel tumor with ileo-ileal invagination. The anatomopathological and immunohistochemical study of the surgical specimen concluded to diffuse small cell non-Hodgkin’s lymphoma, without vascular embolism. The resection limits pass into the healthy zone.

目的 探讨高频超声检查对小儿肠套叠的鉴别诊断价值。方法 选取126例小儿肠套叠患儿,均行高频超声检查,根据临床诊断结果将患儿分为甲组(一过性小儿肠套叠)69例与乙组(持续性小儿肠套叠)57例,比较两组患儿的影像学表现。结果 所有患儿高频超声检查显示小肠包块横切面呈“同心圆征”、纵切面呈“套筒征”。甲组套叠部位的直径与深度分别为(16.14±3.35)mm、(19.59±4.26)mm,乙组套叠部位的直径与深度分别为(18.87±3.68)mm、(27.83±6.37)mm,乙组套叠部位的直径与深度均高于甲组,差异有统计学意义(P<0.05)。乙组套叠肠壁蠕动情况正常/活跃的概率(68.42%)低于甲组(98.55%),套叠肠壁水肿率(15.79%)高于甲组(0%),差异有统计学意义(P<0.05)。结论 两组高频超声检查特征存在差异,甲组通常伴有包块直径小、深度低、肠壁蠕动正常/活跃、无水肿等特征,有持续性小儿肠套叠危险。

Intussusception of the bowel in adults:A review

Intussusception of the bowel is defined as the telescop-ing of a proximal segment of the gastrointestinal tract within the lumen of the adjacent segment.This condi-tion is frequent in children and presents with the classic triad of cramping abdominal pain,bloody diarrhea and a palpable tender mass.However,bowel intussusception in adults is considered a rare condition,accounting for 5% of all cases of intussusceptions and almost 1%-5%of bowel obstruction.Eight to twenty percent of cases are idiopathic,without a lead point lesion.Secondary intus-susception is caused by organic lesions,such as inflam-matory bowel disease,postoperative adhesions,Meckel's diverticulum,benign and malignant lesions,metastatic neoplasms or even iatrogenically,due to the presence of intestinal tubes,jejunostomy feeding tubes or after gas-tric surgery.Computed tomography is the most sensitive diagnostic modality and can distinguish between intus-susceptions with and without a lead point.Surgery is the definitive treatment of adult intussusceptions.Formal bowel resection with oncological principles is followed for every case where a malignancy is suspected.Reduction of the intussuscepted bowel is considered safe for benign lesions in order to limit the extent of resection or to avoid the short bowel syndrome in certain circumstances.

Inverted Meckel’s diverticulum manifested as adult intussusception: Age does not matter

Adult intussusception due to Meckel’s diverticulum (MD) is an uncommon cause of intestinal obstruction. However, the surgeon should still be suspicious of this condition since the non specific symptoms and the rarity of it make a preoperative diagnosis uncertain. Considering the secondary nature of adult intussusception and the necessity of early surgical intervention to avoid morbidity and mortality, we report two cases of intussusception due to MD in adults. A diverticulectomy using a TA stapler was performed in the first patient. In the second patient extensive fibrosis of the adjacent mesentery and thickening of jejunal mucosa were observed, so a segmental resection of the small bowel or affected ileal part and a hand-sewn anastomosis was performed. The postoperative period along with the long term follow-up was uneventful for both patients. The decision between diverticulectomy vs bowel resection can be based on the intussuscepted bowel condition. Early surgical intervention may ensure a favorable outcome.

Adult intussusception:A retrospective review of 41 cases

AIM:To optimize the preoperative diagnosis and surgical management of adult intussusception (AI).METHODS:A retrospective review of the clinical features,diagnosis,management and pathology 41 adult patients with postoperative diagnoses of intussusception was conducted.RESULTS:Forty-one patients with 44 intussusceptions were operated on,24.4% had acute symptoms,24.4% had subacute symptoms,and 51.2% had chronic symptoms.70.7% of the patients presented with intestinal obstruction.There were 20 enteric,15 ileocolic,eight colocolonic and one sigmoidorectal intussusceptions.65.9% of intussusceptions were diagnosed preoperatively using a computed tomography (CT) scan (90.5% accurate) and ultrasonography (60.0% accurate,rising to 91.7% for patients who had a palpable abdominal mass).Coloscopy located the occupying lesions of the lead point of ileocolic,colocolonic and sigmoidorectal intussusceptions.Four intussusceptions in three patients were simply reduced.Twenty-one patients underwent resection after primary reduction.There was no mortality and anastomosis leakage perioperatively.Except for one patient with multiple small bowel adenomas,which recurred 5 mo after surgery,no patients were recurrent within 6 mo.Pathologically,54.5% of the intussusceptions had a tumor,of which 27.3% were malignant.9.1% comprised nontumorous polyps.Four intussusceptions had a gastrojejunostomy with intestinal intubation,and four intussusceptions had no organic lesion.CONCLUSION:CT is the most effective and accurate diagnostic technique.Colonoscopy can detect most lead point lesions of non-enteric intussusceptions.Intestinal intubation should be avoided.

Postoperative intussusception in infants and children:a report of seven cases

Postoperative intussusception is an uncommon but serious condition in infants and children. Here, we report seven cases of postoperative intussusception in infants and children who were seen at our institution over the last 13 y. The patients showed increased nasogastfic drainage, vomiting, lack of stool, and/or growing abdominal dis- tension 2 to 9 d following abdominal surgery. Manual reduction was successful in five cases. In two cases, necro- sis was found and intestinal resection and anastomosis were carded out, No recurrence was observed at six months of follow-up. Postoperative intussusception should be suspected in pediatric surgical patients who showed signs of intestinal obstruction in the early postoperative period.

Successful management of adult lymphoma-associated intussusception by laparoscopic reduction and appendectomy

Although primary gastrointestinal lymphoma is a rare malignancy, it can cause an intussusception in adults and can be a clinically challenging condition to manage. Intussusception could progress to lifethreatening complications if left untreated or could delay chemotherapy if inappropriate surgical management is used. We report a 31-year-old man diagnosed with human immunodeficiency virus who was being treated with antiretroviral therapy. He presented with nausea, vomiting, poor appetite, and intermittent, cramping abdominal pain for over 1 wk. Abdominal computed tomography revealed a well-defined homogeneous mass in the mesenteric root region, together with a long segmental wall thickening in the ileum with ileocolic-type intussusception, which was suspected to be caused by a lymphoma. The intussusception was successfully laparoscopically reduced, and the tumor involvement of the appendix was confirmedby appendectomy with intraoperative frozen section. Systemic chemotherapy was immediately initiated after surgery without the need for bowel resection.

Eosinophilic enteritis presenting as a rare cause for ileo-ileal intussusception

Eosinophilic enteritis,a relatively rare entity,usually involves gastric antrum or proximal small bowel. Our case is rarer in its involvement of the distal small bowel and presents unusually as intussusception. The disease if diagnosed in the initial stages responds well to medical treatment but if associated with complications or misdiagnosed,surgical modality is the treatment of choice. In our case,the patient presented with acute intestinal obstruction due to intussusception and emergency laparotomy with ileoileal anastomosis was done. Histopathology confirmed the diagnosis as eosinophilic enteritis. This case with such a presentation is discussed here.

Acute Intussusception of the Adult in Burkina Faso, a Tropical Area: Our Experience about 30 Cases

Objective: To describe the etiological, clinical and therapeutic aspects of adults’ intussusception at Yalgado Ouedraogo University Hospital in Ouagadougou (CHU-YO), Burkina Faso. Patients and method: This descriptive cross-sectional study was conducted between May 2011 and April 2016 at CHU-YO. All patients with 16 years of age and older operated on for intussusception were included. Results: Thirty patients were identified, 15 men and as many women. Their average age was 37.3 years. A higher frequency was noted between 30 and 39 years. The installation of the symptomatology was insidious in 22 cases and brutal in 8 cases. The reasons for consultation were abdominal pain (30 cases), vomiting (19 cases), intestinal transit stop (18 cases) and rectorrhagia (9 cases). Physical examination noted an abdominal mass in 11 cases and a localized abdominal tenderness in 7 cases. An intussusception coil was identified on ultrasound in 9 cases. All patients underwent surgery under general anesthesia and the approach was laparotomy. Intraoperatively, the intussusception was ileocolic in 15 cases;a right hemi-colectomy was performed. It was colo-colic intussusception in 10 cases and the treatment thus consisted of a left hemi-colectomy. In other 5 cases, intussusception was ileal, requiring ileal resection. The average hospital stay was 11.7 days. Pathologically, the examination was normal in 2 cases. A colic tumor was found in 14 cases and an ileum tumor in 6 cases. In the other 8 cases, it was an inflammatory aspect of the intestine. Conclusion: In tropical Burkina Faso, adult intussusception often occurs on an intestinal tumor. The symptomatology is atypical.

A case of postoperative recurrent intussusception associated with indwelling bowel tube

Intussusception is quite uncommon in adults.We report a rare case of a 76-year-old man with small bowel intussusception induced by two indwelling bowel tubes,the first a jejunal feeding tube and the second an ileus tube.After complete reduction of the first intussusception caused by the jejunal feeding tube and adhesion,reintussusception occurred due to the postoperative adhesion and ileus tube inserted into the bowel after the previous operation for intussusception.Finally,the part of the jejunum with re-intussusception and adhesion,including the place where the previous reduced intussusception had occurred,was resected.This case is a reminder that when there is no mucosal lesion other than an indwelling bowel tube or a hard adhesion/ inflammation around intussusception,the patient should be operated on without delay for resection of the intussusception to prevent re-intussusception,even if the resected bowel is predicted to be long.

Colo-colonic intussusception with post-polypectomy electrocoagulation syndrome:A case report

BACKGROUND Post-polypectomy electrocoagulation syndrome(PPES)can occur after colonoscopic polypectomy and is usually treated conservatively with a positive prognosis.Nevertheless,there can be cases with complications developing.CASE SUMMARY A 58-year-old woman,who had no previous medical history,visited the Emergency Department of another hospital with symptoms of abdominal pain and fever,1 d after multiple colonoscopic polypectomies.An abdominopelvic computed tomography(CT)scan demonstrated colo-colonic intussusception,and she was transferred to our hospital to consider an operation.CT showed colocolonic intussusception with PPES and no evidence of obstruction.The physical examination showed localized mild tenderness on the right sided abdomen.The patient fasted and was admitted for treatment with intravenous antibiotics(piperacillin/tazobactam 4.5 g each 8 h,ornidazole 500 mg each 12 h).After admission,the symptoms got better and a follow-up CT scan demonstrated resolution of the PPES and intussusception.The patient was discharged on hospital day 9.CONCLUSION Colo-colic intussusception can occur with PPES,and it can be properly treated conservatively.

Intussusception due to hematogenous metastasis of hepatocellular carcinoma to the small intestine:A case report

BACKGROUND The commonest sites of extrahepatic metastases from hepatocellular carcinoma(HCC)are the lungs,bones,adrenal glands,and regional lymph nodes.Hematogenous metastasis to the gastrointestinal(GI)tract is a rare condition in patients with HCC,and the prognosis is usually poor.We report,herein,an extremely rare case of a patient with intussusception due to hematogenous metastasis of HCC to the ileum and his long-term survival with multidisciplinary therapy.CASE SUMMARY The patient was a 71-year-old man with a history of chronic hepatitis B,who had undergone three surgeries for HCC.He was treated with sorafenib for peritoneal metastases of HCC.He was admitted to our hospital with chief complaints of abdominal pain and vomiting.Abdominal contrast-enhanced computed tomography imaging revealed a small intestinal tumor,presenting with intussusception and small bowel obstruction.Conservative treatment was started,but due to repeated exacerbation of symptoms,surgery was planned on the 28th d of hospitalization.Partial ileal resection without reducing the intussusception and end-to-end anastomosis was performed.On histological examination,tumor cells were not observed on the serosal surface,but intravascular invasion of tumor cells was seen.Immunohistochemistry was positive for immunohistochemical markers,and a diagnosis of hematogenous metastasis of HCC to the ileum was made.He remains alive 82 mo after the first surgery.CONCLUSION Prognosis of HCC patients with GI tract metastasis is usually poor,but in some cases,multidisciplinary therapy may prolong survival.

Ileo-ileal intussusception caused by diffuse large B-cell lymphoma of the ileum

The occurrence of adult intussusception from small intestinal lymphoma is quite rare.We present an82-year-old man with a two-month history of intermittent abdominal pain,nausea and fatigue.Clinical symptoms included moderate abdominal tenderness in the right lower abdomen.Computed tomography scan of the abdomen revealed a mass in the terminal ileum with the sign of"bowel within bowel"which was suspicious of ileo-ileum intussusception.The patient underwent laparoscopic segmental ileal resection.Pathologic evaluation revealed a diffuse large B cell non-Hodgkin’s lymphoma of the ileum.The postoperative course was uneventful.

Adult intussusception secondary to an ileum hamartoma

Intussusception is a rare condition in the adult population.However,in contrast to its presentation in children,an identifiable etiology is found in the majority of cases.Clinical manifestations of adult intussusception are non-specific and patients may present with acute,intermittent or chronic symptoms,predominantly those of intestinal obstruction.A 27-year-old male patient with recurrent abdominal pain secondary to intussusception is herein reported.The clinical presentation and ultrasonographic findings led to the diagnosis.At laparotomy,an ileal hamartoma was found as the lead point of the intussusception.Surgical management and histopathologic studies are described.A recurrent intestinal obstruction and classic ultrasound findings may lead to the diagnosis of intussusception but surgical exploration remains essential.The principle of resection without reduction is well established.

Laparoscopic management of small-bowel intussusception in a 64-year-old female with ileoal lipomas

A 64-year-old female patient presented with upper ab-dominal pain and vomiting. Ultrasonography showed a hyperechoic mass in the right lower abdomen and computed tomography showed a low-density mass with intestinal invagination. An emergency laparo-scopic right-hemicolectomy was performed, and the resected specimen was found to contain three tumors, which were identified histopathologically as intestinal lipomas. Adult intussusception is relatively rare and difficult to be diagnosed, since most symptoms of adult intussusception are nonspecific. We report our clinical experience of the diagnosis and emergent laparoscopic surgery for an adult patient with intussusception.

An Inflammatory Fibroid Polyp (Vanek’s Tumor) of the Ileum that Presented as Intussusception

Ileoileal intussusceptions caused by inflammatory fibroid polyps are uncommon. Inflammatory fibroid polyps (Vanek’s tumor) are rare benign lesions that originate in the submucosa of the gastrointestinal tract. Here, we report the case of a 54-year-old woman who was admitted with an acute onset of abdominal pain and signs of intestinal obstruction. The ileal segment was resected, and single-layer end-to-end anastomosis was performed. A submucosal polypoid mass measuring approximately 4.5 × 4.0 cm was found. The histopathological analysis revealed an ulcerated mucosal lesion with variable cellularity that was formed by spindle cells with slight mitosis and abundant inflammatory infiltrate that was mainly composed of eosinophils. Immunohistochemistry confirmed the diagnosis of ileal inflammatory fibroid polyps. Cross-sectional imaging (multidetector computed tomography) plays a significant role in diagnosing this condition and guiding its management.
