Recurrent intussusception as initial manifestation of primary intestinal melanoma:Case report and literature review

Enteric intussusception caused by primary intestinalmalignant melanoma is a very rare cause of intestinalobstruction.We herein present a case of a 42-yearold female patient with no prior medical history ofmalignant melanoma,who was admitted with persistentabdominal pain,nausea,and vomiting.A computedtomography scan revealed an intestinal obstruction dueto ileocolic intussusception.An emergency laparoscopy and subsequent laparotomy revealed multiple small solid tumors across the whole small bowel.An oncologic resection was not feasible due to the insufficient length of the remaining small bowel.Only a small segment of ileum,which included the largest tumors causing the intussusception,was resected.The pathologic examination revealed two intestinal malignant melanoma lesions.A systematic clinical examination,endoscopic procedures,and fluorodeoxyglucose positron emission tomography-computed tomography scan all failed to reveal any indication of cutaneous,anal,or retinal melanoma.Hence,the tumor was classified as a primary intestinal malignant melanoma with multiple intestinal metastases.Since a complete oncologic resection of tumors was not possible,in order to prevent future intestinal obstruction,a surgical resection of the largest lesions was performed with palliative intention.The epidemiology,clinical m a n i fe s t a t i o n s,d i a g n o s i s a n d m a n a g e m e n t o f primary intestinal malignant melanoma,and intestinal intussusception in adults are discussed along with a review of the current literature.     

Intestinal malrotation: a rare but important cause of bowel obstruction in adults

PURPOSE: Complications of intestinal malrotation are familiar to pediatric surgeons but are rarely encountered by those caring strictly for adults. The aim of this study was to review our experience with disorders of intestinal rotation in adult patients and to emphasize the clinical presentation, radiographic features, and results of surgical treatment. METHODS: Ten adult patients (mean age, 42 (range, 22–73) years) with complications of intestinal malrotation were identified by review of department records. Clinical presentation, operative treatment, and outcome were recorded. RESULTS: Nine patients presented with obstructive symptoms (five chronic and four acute). A diagnosis of malrotation was made preoperatively in all cases by a small-bowel contrast study or CT scan. Patients were treated by laparotomy with adhesiolysis (4 cases including one paraduodenal hernia and two midgut volvuli), Ladds procedure (4 cases), or duodenopexy and cecopexy (1 case). One patient presented with an acute abdomen and was found to have appendicitis. There was no mortality. Two patients developed complications (wound infection and ileus). Two patients had recurrent episodes of small-bowel obstruction with a mean follow-up of 30 (range, 2–69) months and one required reoperation. CONCLUSIONS: Complications of intestinal rotation can occur in adult patients and may present with chronic or acute symptoms. Prompt recognition and surgical treatment usually lead to a successful outcome. The diagnosis of intestinal malrotation should be considered in any adult patient with signs and symptoms of small-bowel obstruction.

Ileocecal intussusception in an adult: A case report.

Intussusception is relatively rare in adults and differs from the childhood form in its etiology, presentation and treatment. Unlike childhood intussusception, adult intussusception is usually due to underlying pathologic lead points, most probably neoplasms. The main clinical presentation of intussusception in the adult is chronic abdominal pain, and acute adult intussusception is uncommon. Here, we describe an uncommon case of acute ileocecal intussusception due to ileal lymphoid hyperplasia in a 46-year-old woman. Lymphoid hyperplasia of the intestines is a benign reactive process. Intestinal lymphoid hyperplasia has been reported in association with infections and as an allergic response to various foods. In adults, it has been reported to occur in association with immune deficiencies. There were no obvious causes for this patient's ileal lymphoid hyperplasia. We conclude that physicians need to consider intussusception, due to intestinal lymphoid hyperplasia, as a possible cause of acute abdominal pain in adults, even in the absence of any specific medical history.     

Clinical Entity and Treatment Strategies for Adult Intussusceptions: 20 Years-Experience

Purpose Intestinal intussusception in adults is rare and the optimal management of this problem remains controversial. The purpose of this study was to determine the causes of intussusceptions in adults and to assess their treatment. Methods A retrospective review of patients older than aged 18 years who were diagnosed with intestinal intussusception at Tri-Service General Hospital between July 1984 and July 2004 was conducted. Results During the 20-year period, there were 292 patients with intussusception, 24 (8.2 percent) of which were adults. Abdominal pain was the most common presenting complaint (79.2 percent). The diagnosis of adult intussusception was made preoperatively in 18 cases (75 percent) and intraoperatively in 6 cases (25 percent). Of the 24 patients, 20 (83.3 percent) had a defined lesion; 11 (55 percent) lesions were benign and 9 (45 percent) were malignant. In eight patients (33.3 percent), the intussusception was reduced; perforation occurred in one patient (12.5 percent). Segmental resections were performed on 14 patients (58.3 percent), right hemicolectomies on 6 patients (25 percent), laparoscopic low anterior resection on 1 patient (4.2 percent), appendectomy on 1 patient (4.2 percent), and diverticulectomy on 1 patient (4.2 percent). Intraoperative colonoscopy was performed on three patients (12.5 percent) before reduction (lipomas were noted in 2 of the patients (66.7 percent) with limited resection of the ileum and preservation of the antireflux ileocecal valve. There was one perioperative mortality (4.2 percent) and seven postoperative morbidities (29.2 percent). Conclusions Adult intussusception is an unusual and challenging condition and is a preoperative diagnostic problem. We discuss our 20 years of experience in treatment strategies for dealing with such unusual problems. Reprints are not available.     

Mesenteric vasculitis causing ileocecal intussusception as the initial presentation of systemic lupus erythematosus: a case report

Mesenteric vasculitis is one of the most devastating complications of systemic lupus erythematosus (SLE) and may produce a spectrum of complications, including ulceration, hemorrhage, bowel necrosis, perforation, serositis, and ascites. Intussusception is a process in which a segment of intestine invaginates into the adjoining intestinal lumen, causing bowel obstruction. Intussusception in association with SLE has rarely been reported. Here we report a case of SLE whose initial presentation was mesenteric vasculitis causing ileocecal intussusception.

     

Adult duodenal intussusception associated with congenital malrotation

Enteroenteric intussusception is a condition in which full-thickness bowel wall becomes telescoped into the lumen of distal bowel. In adults, there is usually an abnormality acting as a lead point, usually a Meckels＇ diverticulum, a hamartoma or a tumour. Duodeno- duodenal intussusception is exceptionally rare because the retroperitoneal situation fixes the duodenal wall. The aim of this report is to describe the first published case of this condition. A patient with duodeno-duodenal intussusception secondary to an ampullary lesion is reported. A 66 year-old lady presented with intermittent abdominal pain, weight loss and anaemia. Ultrasound scanning showed dilated bile and pancreatic ducts. CT scanning revealed intussusception involving the full-thickness duodenal wall. The lead point was an ampullary villous adenoma. Congenital partial （type r[） malrotation was found at operation and this abnormality permitted excessive mobility of the duodenal wall such that intussusception was possible. This condition can be diagnosed using enhanced CT. Intussusception can be complicated by bowel obstruction, ischaemia or bleeding, and therefore the underlying cause should be treated as soon as possible.     

Acute adult intussusception caused by primary cecal non Hodgkin lymphoma

Intussusception of the bowel is rather rare in adults and in about 80-90% of the cases is secondary to an underlying intraluminal pathology that serves as a lead point. In cases of colonic intussusception malignancy occurs in 63-66% of patients and it is usually adenocarcinoma and rarely lymphoma. The presenting symptoms are non specific and are in most cases of long duration, consistent with a chronic intussusception causing partial intestinal obstruction. We present a rare case of primary colorectal lymphoma in a 29 years old female that was complicated by acute ileocecal intussusception, treated with en bloc resection without reduction.     

Intussusception: Jordan University Hospital experience

BACKGROUND/AIMS: The aim of this study was to retrospectively review all children who presented with intussusception over a 24-year period. METHODOLOGY: The medical records of children who presented with intussusception from July 1979 through July 2003 at Jordan University Hospital were reviewed. RESULTS: One hundred and nine children (74 male, 35 female) presented with intussusception. Their mean age was 16.3 months (range 2 months-14 years). The presenting symptoms were: vomiting (92%), abdominal colic/pain (80%) rectal bleeding (78%), and abdominal mass (65%). Ninety-six cases were ileocolic intussusception (idiopathic type). Eleven patients had small bowel intussusception. Laparotomy was required in 86 cases, manual reduction being successful in 59 (56%); 20 (18%) had bowel resection; 2 had resection of Meckel's diverticulum; and 5 patients underwent Ladd procedure for associated malrotation. CONCLUSIONS: Idiopathic intussusception commonly presenting as an ileocolic type constituted the majority of the cases in the present study, occurring in 96 patients (89.7%). The clinical features were classical, vomiting being the most common. The average interval between the onset of symptoms and presentation to the hospital was 46 hours and barium enema reduction was successful in 20 out of 48 cases in which it was attempted. Surgical intervention was required in 86 cases (81%); of which manual reduction was successful in 59 cases, resection was required in 22 cases and 5 patients required an additional Ladd procedure for associated malrotation.     

Mesenteric vasculitis causing ileocecal intussusception as the initial presentation of systemic lupus erythematosus: a case report

Mesenteric vasculitis is one of the most devastating complications of systemic lupus erythematosus (SLE) and may produce a spectrum of complications, including ulceration, hemorrhage, bowel necrosis, perforation, serositis, and ascites. Intussusception is a process in which a segment of intestine invaginates into the adjoining intestinal lumen, causing bowel obstruction. Intussusception in association with SLE has rarely been reported. Here we report a case of SLE whose initial presentation was mesenteric vasculitis causing ileocecal intussusception.     

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 and chronic presentation of intestinal nonrotation in adults

Intestinal nonrotation has been recognized as a cause of obstruction in neonates and children and may be complicated by volvulus and intestinal necrosis. It is very rarely seen in the adult and may present acutely as a bowel obstruction and intestinal ischemia associated with midgut or ileocecal volvulus, or chronically as vague intermittent abdominal pain. The purpose of this communication is to reveal the pathogenesis and the surgical significance of intestinal nonrotation in adults and to review the English and German language literature since 1923 to establish the optimal therapeutic management. Between 1983 and 1992, we have managed and observed prospectively 10 adults with intestinal nonrotation. In four patients the nonrotation has been detected at emergency laparotomy owing to midgut or ileocecal volvulus. Four patients suffered from chronic symptoms of intermittent volvulus or small bowel obstruction and in two patients the nonrotation has been noted as an incidental finding at laparotomy for another condition. A survey of the literature from 1923 to 1992 revealed 40 adults with symptomatic intestinal nonrotation to which we contribute nine patients. We establish that in the acute symptomatic pattern, only emergency laparotomy can provide the correct diagnosis and decrease the risk of bowel disturbance. In the chronic situation, barium studies of the upper and lower gastrointestinal tract reveal varying degrees of midgut malrotation and confirm the nonrotation in each case. Also, in these forms the explorative laparotomy with a consequent staging of the abdominal situs is to be recommended. All reported cases at our institutions are without complaints after surgery. Adult patients with intestinal nonrotation and acute or chronic obstructive symptoms or those detected incidentally at laparotomy for other conditions should undergo a Ladd procedure because of the risk of midgut volvulus. In this operation, the nonrotation is left in place and the ascending colon is sutured at the colon descendens and sigmoideum. After this procedure the mesenteric pedicle is fixed and the risk of midgut torsion remains minimal.     

Inflammatory fibroid polyp of the ileum]

A new case of ileal inflammatory fibroid polyp (IFP) is reported. A 76 years old woman presented with abdominal pain due to intestinal obstruction; an ileo-ileal intussusception caused by an ulcerated submucosal polyp was found at laparotomy. The IFP usually appears as a solitary benign lesion, rarely located in the ileum. It is made up of fibrous tissue with a dense infiltrate composed predominantly of eosinophils.     

Small intestinal neoplasms

Small intestinal neoplasms are uncommonly encountered in clinical practice. They may occur sporadically, in association with genetic diseases (e.g., familial adenomatous polyposis coli or Peutz-Jeghers syndrome), or in association with chronic intestinal inflammatory disorders (e.g., Crohn's disease or celiac sprue). Benign small intestinal tumors (e.g., leiomyoma, lipoma, hamartoma, or desmoid tumor) usually are asymptomatic but may present with intussusception. Primary malignancies of the small intestine-including adenocarcinoma, leiomyosarcoma, carcinoid, and lymphoma-may present with intestinal obstruction, jaundice, bleeding, or pain. Extraintestinal neoplasms may involve the intestine via contiguous spread or peritoneal metastasis. Hematogenous metastases to the intestine from an extraintestinal primary are unusual and are most typical of melanoma. Because the small intestine is relatively inaccessible to routine endoscopy, diagnosis of small intestinal neoplasms is often delayed for months after onset of symptoms. When the diagnosis is suspected, enteroclysis is the most useful imaging study. Small bowel endoscopy (enteroscopy) is increasingly widely available and may permit earlier, nonoperative diagnosis.     

Situs inversus abdominus and malrotation in an adult with Ladd＇s band formation leading to intestinal ischaemia

Situs inversus abdominus with rotational anomaly of the intestines is an extremely rare condition. Although intestinal malrotation has been recognized as a cause of obstruction in infants and children and may be complicated by intestinal ischaemia, it is very rare in adults. When it occurs in the adult patient, it may present acutely as bowel obstruction or intestinal ischaemia or chronically as vague intermittent abdominal pain. Herein, we present an acute presentation of a case of situs inversus abdominus and intestinal malrotation with Ladd's band leading to infarction of the intestine in a 32 year old woman.     

Abdominal CT findings may suggest coeliac disease

BACKGROUND: Coeliac disease is the most common gastrointestinal immunological disorder in the western countries. Many adult patients present non-specific symptoms and signs of malabsorption such as chronic diarrhoea, anaemia, weight loss and abdominal distention. In non-specific and doubtful conditions, computed tomography is often the first medical examination performed. In a clinical practice, a critical review of computed tomography signs is therefore mandatory. AIMS: To evaluate the abdominal computed tomography findings, which are useful to suggest the presence of coeliac disease in adult patients. PATIENTS AND METHODS: The computed tomography studies of 28 coeliac patients were reviewed, looking for any intestinal and extraintestinal abnormality. The computed tomography findings evaluated were: abnormalities of intestinal fold pattern, bowel dilatation, fluid and air excess, duodenal abnormalities, intestinal intussusception, bowel wall thickening, lymphadenopathy, ascites, intestinal stenosis, mesenteric vascular changes. The abdominal computed tomography of a group of 30 normal subjects was also analysed. RESULTS: Intestinal fold pattern abnormalities were seen in 23/28 patients. Intestinal dilatation was seen in 21/28. Fluid excess in 18/28 and lymphadenopathy was seen in 12/28 patients; engorgement of mesenteric vessels in 7/28. Bowel wall thickening was observed in 6/28 patients and transient intussusception was observed in 6/28 patients. Increased air content within the bowel in 4/28 and ascites in 2/28 patients. Bowel dilatation together with fluid excess was observed in 18/28 patients. None of the above mentioned abnormalities abnormalities were seen in normal subjects. CONCLUSIONS: Data of the present study show that several abdominal computed tomography findings may be seen in coeliac adult patients; these findings should be taken into consideration with a high in level of suspicion by radiologists, to avoid diagnostic delay and unnecessary diagnostic and therapeutic procedures.     

Laparoscopic Surgery for Adult Intussusception: Case Series

BackgroundIntussusception is a rare condition in adults which accounts for 1% of all intestinal obstructions. It usually requires surgical treatment and the classic approach is laparotomy. This article presented six adult patients who underwent laparoscopic surgery for intestinal obstruction due to intussusception.MethodBetween January 2017 and July 2019, six adult patients underwent laparoscopic surgery for intestinal obstruction due to intussusception. The patients were evaluated in terms of presenting symptoms, diagnosis, treatment modality, morbidity, mortality and histopathological results.ResultsAll patients presented with acute (50%) or subacute (50%) symptoms. All patients had intestinal obstruction (partial, complete) findings. Intussusception was diagnosed by abdominal computed tomography (CT). The patients with ileocolic and colo-colonic intussusception underwent colonoscopy. In the preoperative period, the etiology of intussusception (neoplasm, idiopathic, etc.) was diagnosed only in one patient (16.6%). Two patients underwent laparoscopic segmental small bowel resection, two patients underwent laparoscopic right hemicolectomy, one patient underwent laparoscopic left hemicolectomy, and one patient underwent laparoscopic anterior resection. None of the patients developed intraoperative or postoperative complication. The histopathological examination revealed malignancy in two patients (33.3%).ConclusionCT is helpful in diagnosing of adult intussusception. However, it is usually difficult to define the underlying pathology with CT. Laparoscopic approach seems to be safe and effective as open surgery, both in diagnosis and treatment of intussusception.
