Abstract

Introduction

The initial diagnosis of intussusception in adults very often can be missed and cause delayed treatment and possible serious complications. We report the case of an adult patient with complicated double ileoileal and ileocecocolic intussusception.

Case presentation

A 46-year-old Caucasian man was transferred from the gastroenterology service to the abdominal surgery service with severe abdominal pain, nausea, and vomiting. An abdominal ultrasound, barium enema, and abdominal computed tomography scan revealed an intraluminal obstruction of his ascending colon. Plain abdominal X-rays showed diffuse air-fluid levels in his small intestine. A double ileoileal and ileocecocolic intussusception was found during an emergent laparotomy. A right hemicolectomy, including resection of a long segment of his ileum, was performed. The postoperative period was complicated by acute renal failure, shock liver, and pulmonary thromboembolism. Our patient was discharged from the hospital after 30 days. An anatomical pathology examination revealed a lipoma of his ileum.

Conclusions

Intussusception in adults requires early surgical resection regardless of the nature of the initial cause. Delayed treatment can cause very serious complications.

Introduction

Intussusception was reported for the first time in 1674 by Barbette of Amsterdam. Intussusception, or 'introsusception' as it was named then, was later detailed in 1789 by John Hunter [1]. In 1871, Sir Jonathan Hutchinson was the first to successfully operate on a child with intussusceptions [2]. Intussusception is relatively frequent in children but is rare in adults [3]. Adult intussusception represents 1% of all bowel obstructions and 5% of all bowel intussusceptions [4]. In contrast to pediatric intussusception, which is idiopathic in 90% of cases, adult intussusception has an organic lesion in 70% to 90% of cases [5]. Adult intussusception can present with atypical symptoms of an acute, subacute, or chronic clinical entity, and timely diagnosis is often missed, leading to a delay in proper treatment [3]. Although it is generally accepted that adult intussusception requires surgical resection because of the underlying pathology in the majority of patients, the extent of resection and the question of whether the intussusception should be reduced remain controversial [6]. The aim of this report is to present a rare case of double ileoileal with ileocecocolic intussusception in an adult patient. The case was caused by the submucosal lipoma of the ileum and resulted in serious complications due to delayed surgical treatment.

Case presentation

A 46-year-old Caucasian man was transferred from the gastroenterology service to the abdominal surgery division for intractable severe abdominal pain accompanied by nausea and vomiting. He had a four-month history of abdominal discomfort, namely intermittent abdominal cramping pain of mild to moderate severity in his middle and lower quadrants. His medical history was unremarkable. A review of his systems revealed weight loss of nine pounds during the previous three months. Eight days earlier, he had been admitted to the gastroenterology service for a diagnostic work-up and medical treatment. During the initial physical examination, he appeared in good general condition, was normothermic, and had a slightly distended abdomen, which, however, was soft and non-tender. No rebound effect was elicited. A rectal examination revealed no masses or blood. Laboratory results were all within normal range. An abdominal ultrasound showed a hyperechoic mass in his ileocecal region. A barium enema showed an oval-shape filling defect in his ascending colon (Figure 1). An abdominal computed tomography (CT) scan showed an irregular 'target' and a 'sausage'-shape soft-tissue mass with thickened walls of his cecum and terminal ileum (Figure 2). Although all diagnostic procedures clearly suggested colonic obstruction, our patient refused transfer to the surgery department until the pain, nausea, and vomiting became persistent and more severe. During his admission to surgery, plain abdominal films clearly demonstrated signs of intestinal obstruction, air-fluid levels in his small intestine, and the absence of air in his colon. Our patient underwent an emergent median laparotomy. During the operation, a large intussuscepted mass was found. It was located in the region of his ascending colon and hepatic flexure, into which a large segment of his ileum, appendix, cecum, and part of his ascending colon were invaginated. Because of compromised perfusion and swelling of his colonic wall and because of an unsuccessful attempt at manual desinvagination, a round incision in his ascending colon was made, and his invaginated cecum and terminal ileum were pushed backward with the intention of preserving as much viable small bowel as possible. An in situ macroscopic view showed that a 15 cm segment of his ileum was intussuscepted into the distal 20 cm of his terminal ileum, which, together with his appendix and cecum, subsequently intussuscepted into his ascending colon, resulting in a double ileoileal and ileocecocolic intussuception. His cecum and about 30 cm of his terminal ileum were entrapped in the intussuscipiens and had necrotic changes in their walls (Figure 3). A right hemicolectomy that included an approximately 40 cm segment of his ileum was performed. The continuity of the digestive tube was reestablished by primary single-layer end-to-end ileotransverse anastomosis with 3.0 polydioxanone sutures.

The macroscopic examination of the specimen identified a 4 cm pendulant polypoid mass in his terminal ileum (Figure 4). An anatomical pathology examination of the resected specimen revealed a submucosal tumor of his ileum about 3.5 cm in diameter with features of a benign lipoma (Figure 5).

The postoperative course was eventful. As a result of toxic syndrome (probably due to protracted preoperative intestinal obstruction and delayed surgical treatment), the postoperative period was complicated by high fever (39.5°C), hypotension, acute renal failure within the first six postoperative hours, and significant abnormalities of liver function tests on the first postoperative day. Multiorgan failure ensued, and our patient was transferred to the intensive care unit. Renal failure resolved after hemodialysis sessions carried out each day for one week. On the twentieth postoperative day, the patient developed all clinical manifestations of pulmonary embolism which was treated with heparin initially, and subsequently with warfarin. On the 30th postoperative day, our patient was discharged from the hospital in good condition.

Discussion

Intussusception remains a rare condition in adults, representing 1% of bowel obstructions or 0.003% to 0.02% of all hospital admissions [3]. In contrast to pediatric intussusception (which is mainly of unclear etiology), adult intussusception in 90% of cases is secondary to an organic lesion within the bowel wall [710]. Although the mechanism of development is unknown, it is believed that any lesion in the intestinal wall or irritant within the lumen which alters normal peristalsis is able to initiate an invagination [7, 11]. There are different classification systems of intussusceptions. In general, intussusception is classified as enteric or colonic according to the location of the pathologic lead point [12]. The enteric group includes jejunojejunal, ileoileal, and ileocolic intussusceptions, whereas the colonic group includes ileocecal-colic, colocolonic, sigmoidorectal, and appendicicocecal intussusceptions. Ileocolic and ileocecal-colic intussusceptions are distinguished by the site of the pathologic lead point. In ileocolic intussusception the lead point is in the ileum, but in ileocecal-colic intussusception the lead point is in the ileocecal valve. However, in clinical practice, it is difficult to differentiate some of the complicated advanced forms of ileocecal-colic intussusceptions [13]. In the present case, although the intussusception was ileocecal-colic, the initial pathologic lead point was located in the ileum and caused the double ileoileal intussusception (Figure 3). Then the double ileoileal intussusception continued to act as a lead point through the cecum toward the ascending colon, thus causing ileocecal-colic intussusceptions. A similar case with double invagination of the ileum was reported by Constanzo and colleagues [14] (2007).

Adult intussusception presents with a variety of non-specific symptoms that can have an acute, intermittent, or chronic course. Since only about 9% to 10% of adult intussusceptions present with the typical triad of abdominal pain, palpable abdominal mass and bloody stool, the preoperative diagnosis is usually very difficult [7].

Early and accurate diagnosis is essential because a delay can lead to intestinal ischemia, perforation, and peritonitis and result in a potentially fatal outcome [1517]. A number of different diagnostic methods - such as CT scan, barium imaging, abdominal ultrasound, endoscopic examination, and angiographic and radionucleotide studies - have been described as useful in the diagnosis of intussusceptions [18, 19]. The abdominal CT scan has been proven to be the most useful diagnostic method, and ultrasound is the second most accurate; both reveal a characteristic 'target' or 'sausage'-shape mass. In our case, the abdominal CT scan, done nine days before transfer to surgery, showed a characteristically laminated 'target mass' in the ileocecal region (Figure 2); however, the abdominal pain and accompanying symptoms did not correlate with the severity of the radiological findings. Because our patient was not willing to undergo surgical treatment at this stage, the gastroenterology team performed a barium enema examination aiming at both diagnostic and therapeutic effects. However, this procedure yielded no therapeutic results in terms of reduction. This confirmed the findings of other authors [9, 15], who reported that barium studies, despite good diagnostic and therapeutic effects in children with presumed diagnosed intussusception, do not have any considerable hydrostatic reducing effect in adults, because of the high incidence of underlying anatomical abnormalities.

The treatment of intussusception in adults is surgical because of the high incidence of underlying malignant pathology and serious complications that can develop as a result of intestinal obstruction and vascular strangulation [7, 11]. Most surgeons agree that resection is necessary, particularly in colonic intussusceptions and in older patients, because of the possibility of a malignant tumor [3, 5, 9, 15, 20, 21]. It remains debatable whether reduction of the intussuscepting lesion should be attempted during an operation or whether 'en bloc' resection should be carried out without attempting reduction [9, 15, 21]. Previous reports advocated reducing the intussusception before resection [22, 23]. Some authors have recommended a selective approach to resection, depending on the site of intussusception, which influences the type of pathology [12, 15]. Chang and colleagues [24] (2007) recommended operative reduction for small-bowel intussusceptions but not for colonic intussusceptions. Gupta and colleagues [25] (2011) reported resection in 70% of colonic intussusceptions. The potential disadvantages of this approach are intraluminal seeding and tumor dissemination via venous flow, perforation and seeding of infection and tumor cells into the peritoneal cavity, and increased risk of anastomotic complications [26]. The advantages of intraoperative reduction of the intussusception prior to resection, especially when the small bowel is affected, are that it may preserve a considerable length of bowel and thereby prevent development of short-bowel syndrome. Begos and colleagues [15] are proponents of resection without attempting reduction when the bowel is inflamed, ischemic, or friable and in obvious colocolic intussusception (with the high likelihood of malignancy). In all other cases, reduction should always be attempted initially. In the present case, intraoperative findings indicated that a large length of small bowel was intussuscepted into ileoileo and cecocolic intussusception with vascular changes in the wall of the colon. So to preserve as much viable small bowel as possible, we made a round incision in the ascending colon and pushed proximally (backward) the cecum with the terminal ileum (Figure 3). Then after a checking for bowel viability, we performed a right hemicolectomy with resection of a long segment of the ileum with subsequent creation of primary single-layer anastomosis between the ileum and transverse colon.

The postoperative complication rate in adult intussusceptions is still reported by some authors [12, 24] to be relatively high. Although there is no existing research on a large group of patients, complications are much more a consequence of missed diagnosis and delayed treatment than the result of anastomotic problems, according to current studies [7, 12, 24]. Yakan and colleagues [12] (2009), in their retrospective study, reported a 20% postoperative complication rate and a perioperative death rate of 5% due to severe sepsis complicated by multiple organ failure six days after the operation, but there was no leak of anastomosis. Also, Chang and colleagues [24] (2007) reported a postoperative death rate of 5.5% in adult intussusceptions treated surgically. The postoperative period was associated with serious complications in our case as well. However, thanks to multidisciplinary active treatment, our patient was discharged from the hospital in good condition on the 30th postoperative day.

In conclusion, the diagnosis of intussusception in adults can be difficult because of atypical and episodic symptoms. It is very important to intervene surgically early on, something that was not done in this case. A high level of clinical suspicion and an abdominal CT scan are most useful tools for making a timely diagnosis.

Conclusions

This case, as well as a review of the literature, showed that a missed initial diagnosis of intestinal intussusception in adults can delay proper treatment and cause serious consecutive complications. Therefore, early surgical treatment is needed regardless of the etiology.
