Adult intussusception: a systematic review of current literature.

BACKGROUND: Intussusception in adults is a rare condition characterized by a low incidence, which complicates the establishment of standardized management protocols unlike those readily available for pediatric cases. This study presents a case series from our institution alongside a systematic review of existing literature. The objective is to delineate effective management strategies for adult intussusception. METHODS: A systematic search of databases was conducted covering the period from January 2000 to May 2024. The study focused on adult patients diagnosed with intussusception either pre-operatively or intraoperatively and managed with either surgical intervention or conservative methods. The analysis also included retrospective review of patient records from our institution, specifically targeting individuals over 18 years of age, to determine the predominant types of intussusception and identify any pathological lead points associated with these cases. RESULTS: In our study, a total of 1,902 patients were included from 59 selected articles, with a mean age of 52.13 ± 14.95 years. Among them, 1,920 intussusceptions were diagnosed, with 98.3% of cases identified preoperatively. Computed tomography (CT) scan was the primary diagnostic modality used in 88.5% of cases. Abdominal pain was the predominant presenting symptom, observed in 86.23% of cases. Only 29 out of 1,920 cases underwent attempted reduction, while the majority required surgical resection due to the high incidence of malignancy in adult cases. The most common type of intussusception identified was colocolic (16.82%), followed by enteric (13.28%), ileocolic (4.89%), and ileocaecal (0.78%) types. A pathological lead point was observed in 302 out of 673 patients (44.84%), with a notably higher frequency of malignancy associated with colocolic intussusception. CONCLUSION: Surgical management remains the cornerstone in treating adult intussusception, particularly in cases involving the colocolic type, where there is a significant risk of underlying malignancy. Attempts at reduction are generally avoided due to the potential risk of tumor dissemination, which could adversely impact patient outcomes. Contrast-enhanced computed tomography (CECT) of the abdomen is pivotal for accurately diagnosing intussusceptions and guiding appropriate management strategies. It is imperative to adhere strictly to oncological principles during surgical interventions to ensure optimal patient care and outcomes.

Unkinking The Kinked: A Rare Intussusception In The Paediatric Emergency Department.

Intussusception is the introversion of the proximal intestinal loop into the distal downstream part of the intestinal loop, leading to gut wall oedema and restriction of blood supply. A high index of suspicion is required to diagnose it timely. Mostly infants aged less than a year are vulnerable to this surgical emergency presenting mostly with abdominal distension, vomiting, reluctance to feed and bright red jelly-like stools which, if left unrecognised, may result in the development of ischaemic portion of the gut and catastrophic outcomes. We present the case of a 60-day-old baby who presented in the Paediatric Emergency Department with progressive abdominal distension and bloody stools. Abdominal X-ray showed dilated bowel and ultrasound imaging showed a target sign positive for intussusception. The baby was rushed to the operating room (OR) due to delayed presentation, where an uneventful exploratory laparotomy was performed. Acute intestinal intussusception remains a cause of low morbidity and mortality rates if recognised earlier.

Pediatric Colonic Anastomosis: Can Method of Anastomosis and Wound Closure be of Help?

Background: Enhanced recovery after surgery (ERAS) protocols after colorectal surgery focused on reduced bowel preparation, standardized feeding schedule, earlier return of bowel function, and earlier resumption of normal activities. ERAS in pediatric surgical practice is not well established. The present study aims to present the results of two colonic anastomosis techniques of interrupted single-layered closure: Halsted (Horizontal Mattress) and Matheson (serosubmucosal or appositional extramucosal) along with two different methods of colostomy wound closure and their influence on the adoption of ERAS protocol of early feeding and early discharge. Materials and Methods: This single institute-based randomized control study was conducted in a tertiary care facility in Kolkata for 2.4 years. Patients were chosen randomly for serosubmucosal (Group I) and full-thickness (Group II) anastomosis. Results: Among total of 91 patients (Group I-43 and Group II-48), Return of bowel sounds and passage of bowel averaged 1.51 ± 0.51 and 1.91 ± 0.55 days in Group I and 1.91 ± 0.57 and 3.9 ± 0.66 days in Group II, respectively. Postoperative hospital stay averaged 5.88 ± 1.12 days in Group I and 8.9 ± 1.17 days in Group II. Overall 15 (16.48%) patients had complications among which SSI (Suprficial surgical site infection) and minor leaks (Group I-3 and 1 and Group II-5 and 3, respectively) which were treated conservatively (Clavien-Dindo Grade-I) and three major leaks under Group II requiring surgical intervention (Clavien-Dindo Grade-III). Conclusion: This study concludes that the technique of colostomy closure in the form serosubmucosal closure helps in the implementation of ERAS protocol by producing early bowel movement, early initiation of food, and less postoperative complications.

Laparoscopic limited hemicolectomy for descending colo-colic intussusception in an adult.

Intussusception in adults represents 1% of bowel obstructions and up to 0.02% of all hospital admissions. Amongst these, colo-colic intussusception of the descending colon forms the rarest of causes due to the fixed nature of the descending colon. Most of adult intussusceptions follow a lead point and are commonly due to colonic malignancy which may get missed on pre-operative evaluation. Surgery is usually warranted as these patients are usually symptomatic and at risk of vascular compromise, leading to perforations and obscure malignancies. We present a case of laparoscopic limited hemicolectomy and primary anastomosis in a middle-aged male who presented with colo-colic intussusception, which appeared to be following a malignant mass on imaging and lipoma on colonoscopic biopsy done twice. Keeping in mind the possibility of a malignant lead point, no attempt was made to reduce the intussusception and a vessel first approach with 5 cm margin on either side was performed.

Are right-sided colectomies for neoplastic disease at increased risk of primary postoperative ileus compared to left-sided colectomies? A coarsened exact matched analysis.

INTRODUCTION: The objective of this study was to determine whether right-sided colectomies (RC) were associated with a higher incidence of primary postoperative ileus (pPOI) compared to left-sided colectomies (LC). METHODS: Patients who underwent elective colectomy for neoplastic disease between 2012 and 2016 were identified using the American College of Surgeons National Surgical Quality Improvement Program database. RC and LC were defined as having an ileocolic or colocolic/colorectal anastomosis, respectively. Coarsened Exact Matching (CEM) was used to balance the two groups (1:1) on important confounders. The association between type of colectomy and pPOI, defined as POI in the absence of intra-abdominal sepsis, was then assessed in a multiple logistic regression analysis of the matched data. RESULTS: Of 40,636 patients who underwent a colectomy for neoplastic disease, 15,231 underwent a RC and 25,405 a LC. After CEM, 12,949 matched patients remained in each group, and all important confounders were well balanced. The incidence of pPOI was higher in the RC group (11.5% vs. 8.8%, p < 0.001). On multiple logistic regression, RC was associated with a 35% higher odds of developing pPOI compared to LC (OR 1.35, 95% CI 1.25-1.47). RC was also associated with increased risk for NSQIP-defined major morbidity (OR 1.10, 95% CI 1.01-1.20), 30-day readmission (OR 1.16, 95% CI 1.06-1.27), and increased length of stay (ß = 0.16 days, 95% CI 0.11-0.22). CONCLUSION: pPOI is more common after RC than LC. Future research should aim at better understanding the pathophysiology behind this increased risk and identifying interventions to mitigate pPOI in this population.

Colocolic intussusceptions in children: a pictorial essay and review of the literature.

Colocolic intussusception is a variation of intussusception that is rarely encountered in pediatric patients and as such can prove to be a diagnostic challenge for both the emergency clinician and radiologist. Knowledge of the presentation and imaging findings in these cases can expedite diagnosis and guide the patient to appropriate treatment. The demographics, clinical symptoms, imaging findings, and eventual surgical and pathologic outcomes of 8 children with colocolic intussusception will be presented in this pictorial essay, with a review of the available literature.

Colo-colic intussusception in an adult caused by lipoma: Case report of a rare condition.

This report describes the case of a 56-year-old woman who presented at the emergency room with a 3-week history of severe, intermittent abdominal pain. A CT scan revealed colo-colic intussusception caused by a large, substenosing mass with predominant adipose density. Subsequent endoscopic examination with biopsy revealed a necrotic tissue covering the mass, without definitive histological characterization. A second biopsy led to the extremely rare diagnosis of colo-colic lipoma. While intussusception is rare in adults, it's important to consider it as a differential diagnosis, especially when presenting with abdominal pain and signs of bowel obstruction. Timely diagnosis and appropriate treatment are essential to prevent complications.

The Importance of Abdominal Pain in the Elderly: An Unlikely Diagnosis of 17 cm Colo-Colonic Intussusception.

We report an interesting case of a 17 cm colo-colonic intussusception involving the transverse colon, caecum, and distal small bowel in a previously healthy 79-year-old man. The patient presented to the emergency department with a two-day history of mild, left to right iliac fossa abdominal pain, with no other concerning symptoms. He had a CT of the abdomen and pelvis with contrast for suspected subacute bowel obstruction secondary to recurrent bowel cancer. This was reported as colo-colonic intussusception. Following a surgical review, he was transferred from the local district general hospital for an exploratory laparotomy and underwent a right hemicolectomy with primary ileocolonic anastomosis the same evening. The patient was discharged seven days later following an unremarkable post-operative recovery. Final histology confirmed a mucinous adenocarcinoma of the caecum with postoperative cancer staging as T2N0M0. Following discussion at the colorectal multidisciplinary meeting, no adjuvant therapy was advised, and he was placed on the standard colorectal cancer surveillance program for the next five years.

Colocolic intussusception as a rare cause of intestinal obstruction in a preschool child: A case report.

INTRODUCTION AND IMPORTANCE: Colocolic intussusception occur in less than 5 % of all cases of intussusception. Median age at presentation is 4.4 years. Usually presents with features of intestinal obstruction. Common causes include pathological lead points like juvenile polyps, Meckel's diverticulum and lymphoma. However, rarely occurs without an organic cause as presented in the index case. CASE PRESENTATION: We present a case of colocolic intussusception in a 5-year-old boy with clinical evidence of blood-stained mucoid stools, abdominal distention and post prandial vomiting. CT-scan confirmed the clinical diagnosis. Surgical exploration revealed left-sided colocolic intussusception without a pathological lead point. CLINICAL DISCUSSION: Most cases of colonic intussusception have a pathological lead point. Clinical features are unspecific but mostly present with intestinal obstruction, hence, a CT-scan aids in establishing the diagnosis. CONCLUSION: Colocolic intussusception is a rare subtype of intussusception in the paediatric age group especially in the absence of a pathological lead point. This case report presents a rare case of colocolic intussusception without pathological lead point, highlighting the importance of advanced imaging modalities like CT-scan in establishing the diagnosis and guiding management.

Intussusception secondary to anaphylactic reaction to salmon roe (ikura).

Anaphylactic food reaction often involves gastrointestinal symptoms, such as vomiting and abdominal pain, but to date, there have been no publications documenting the association between food hypersensitivity and intussusception. Herein is reported the case of a 2-year-old boy with intussusception accompanied by anaphylactic food reaction. The patient without known allergies complained of severe abdominal pain following ingestion of salmon roe for the first time. Dyspnea, wheezing and generalized urticaria also developed. Subsequently, he had stools containing jelly-like blood with mucus. At hospital arrival, physical examination identified an abdominal mass in the right lower quadrant; imaging confirmed the diagnosis of colo-colic intussusception. This patient was successfully treated with enema and no pathological findings were identified via radiology. Laboratory results supported the presence of IgE-mediated allergy to salmon roe in the present patient. To our knowledge, this is the first report to describe the possible association between intussusception and a hypersensitive food reaction.

Delayed enterocutaneous fistula after 17 years of gunshot wound injury: a case report.

Enterocutaneous fistula (ECF) is a common complication of abdominal surgery. Postoperatively, it may be the result of a small intestinal injury or an anastomosis leak, and it typically manifests days or weeks following surgery. Case presentation: A 56-year-old man with a history of a gunshot wound injury in the abdomen with colon injury managed for colocolic anastomosis 17 years earlier presented to our hospital's general surgery clinic with the complaint of drainage at the scar area. It was discovered that he had an ECF. The patient underwent a laparotomy. Fistula tract excision and segmental colon resection with colocolic anastomosis were done. Clinical discussion: ECF formation after an extraordinarily long latency due to an anastomotic leak, which has not been previously documented in the literature, is a distinctive aspect of the case. As a result, surgeons should consider ECF in their differentials for patients with a history of abdominal operations. Conclusion: Surgical management is the definitive treatment of ECF after proper resuscitation and stabilization of the patient's condition. Preoperative imaging is crucial for determining the anatomy of the fistula and any associated intra-abdominal pathology.

Adult Colocolic Intussusception: A Rare Case of Intestinal Obstruction.

Intussusception occurs when a part of the intestine slides into its distal adjacent portion and is a surgical emergency. Adult colocolic intussusception is rare, but it is a severe condition and is usually associated with a presence of a tumoral process. We present the case of a frail male patient admitted to our emergency department with abdominal pain, prostration, and dyspnea. The patient was diagnosed with colocolic intussusception and was submitted to a subtotal colectomy and ileostomy. Patients with colocolic intussusception usually present with chronic abdominal pain and signs of intestinal obstruction. Abdominal CT scan facilitates the diagnosis, but most cases are only diagnosed intraoperatively. Given the high probability of colon cancer, the treatment involves an oncological resection of the intestinal segment. Colocolic intussusception is a rare cause of intestinal obstruction in adults where a high suspicion index is of paramount importance, especially considering that most of the diagnoses are made at surgery.

Colocolic Intussusception in Children: A Case Series and Review of the Literature.

Background: Colocolic intussusception is a rare subtype of intussusception mostly caused by juvenile polyps. The treatment of colocolic intussusception caused by other pathologic lead points in children remains poorly understood. Method: A systematic literature review was performed between January 2000 and June 2021 to characterize the comprehensive treatment of colocolic intussusception in children. This report also included patients admitted to our center between January 2010 and June 2021 who were not previously reported in the literature. Results: We identified 27 patients in 20 studies in addition to 17 patients from our center for a total of 44 patients (median age, 4.4 years; 52.3% male). The lead point was identified in 40 patients (40/44, 90.9%). The most common lead point was juvenile polyps (19/44, 43.2%). A therapeutic enema was performed in 15 patients with colocolic intussusception caused by juvenile polyps and was successful in 9 patients (9/15, 60.0%). Colonoscopic polypectomy was subsequently performed in 8 patients and was successful in 7 patients (7/8, 87.5%). The other patient had undergone laparoscopic exploration, and no abnormality was found. Subsequently, the patient underwent open surgery. The patients with colocolic intussusception caused by other pathologic lead points almost underwent surgical treatment (15/21, 71.4%), including 13 open surgeries and 2 laparoscopic surgeries. Conclusion: A therapeutic enema followed by colonoscopic polypectomy is feasible to treat colocolic intussusception caused by juvenile polyps unless the patient has bowel perforation; however, surgery is sometimes needed. For patients with colocolic intussusception caused by other pathologic lead points, open surgery remains the primary treatment.

Colocolic intussusception secondary to colonic adenocarcinoma with impending caecal perforation in an elderly patient: A rare case report.

INTRODUCTION: Intussusception is a surgical emergency in which a part of the intestine slides into the distal adjacent part. Adult colocolic intussusception secondary to a tumoral process is a rare but serious clinical condition requiring immediate surgical intervention. CASE PRESENTATION: We report a case of a 65-year-old male patient presenting with abdominal pain and distention, subsequently diagnosed with colocolic intussusception in the descending colon with closed-loop bowel obstruction with impending caecal perforation. An exophytic mass on the descending colon was discovered intra-operatively, prompting a subtotal colectomy with ileosigmoidal anastomosis and loop ileostomy with the suspicion of malignancy. The histopathological examination of the surgical specimen concluded a moderately-differentiated colonic adenocarcinoma with 40% mucinous component. CLINICAL DISCUSSION: Adult intestinal intussusception is a rare but serious condition differing greatly in etiology from its pediatric counterpart. Its preoperative diagnosis is challenging in adults, which appears to be due to its imprecise presenting signs and symptoms; thus, the condition can be mistaken for other causes of intestinal obstruction. Adenocarcinomas remain the most common cause of malignant tumors in the colon, which also makes them one of the causes for colocolic intussusception. CONCLUSION: Intussusception can appear as a surgical emergency even in the elderly, necessitating prompt surgical intervention to avoid intestinal ischemia and gangrene. Its diagnosis can be aided to a great degree by CT imaging.

Atypical endoscopic finding of colocolic intussusception: case report and literature review.

Background: Adult-onset colonic intussusception is a rarely encountered condition that leads to large intestinal obstruction with time. Patients often present with a variety of symptoms that are non-specific making it challenging to arrive at a definitive diagnosis. This is worrying as diagnostic delay could lead to a significant increase in morbidity and mortality. We wish to present and describe a case of an atypical endoscopic finding of colocolic intussusception secondary to ascending colon cancer. Case Description: Sixty-seven-year-old lady was referred for 1 month's duration of passing melenic stools with mucus followed by a week's complain of hematochezia. Clinical examination and other relevant blood results were unremarkable except for iron deficiency anemia. Initial colonoscopy revealed a large mass within the splenic flexure with inconclusive biopsies. A more detailed colonoscopy repeated the following day revealed a massive, black-to-yellowish lesion within the splenic flexure with no viable mucosa seen. Colonic bezoar was initially suspected, however various endoscopic retrieval methods proved futile. Switching to a slimmer diagnostic gastroscope, the colon was carefully negotiated until a large ulcer was found within the ascending colon, adjacent to the mass' origin. An emergency CT abdomen and subsequently extended right hemicolectomy performed revealed a colocolic intussusception with sealed perforation secondary to an ascending colonic mass acting as an intussusceptum. Histopathology evaluation confirmed an ascending colon adenocarcinoma (pT2N0M0) amidst a background of extensive ischemic changes. Conclusions: Endoscopic descriptions of colonic intussusception are unusual given their rarity. Furthermore, these lesions can mimic a colonic bezoar as a result of fecal accretion and this can ultimately lead to false diagnostic and therapeutic decisions. In such instances, clarification with a CT scan before management decision can potentially avert unnecessary endoscopic intervention and complications.

Colonic Lipoma Causing Bowel Intussusception: An Up-to-Date Systematic Review.

BACKGROUND: Colonic lipomas are rare and can sometimes cause intussusception. The aim of this review was to define the presentation and possible management for colocolic intussusception caused by colonic lipomas. METHODS: A systematic search for patients with colocolic intussusception caused by colonic lipoma, including all available reports up to 2021. Epidemiological, clinical, laboratory, and instrumental data and details about the treatments performed were gathered. RESULTS: Colocolic intussusception caused by lipoma is more frequent in women (57%), occurring between 40 and 70 years of age. Up to 83% of patients report abdominal pain, followed by constipation (18%), rectal bleeding (16%), and diarrhea (12%), with abdominal tenderness (37%), and distension in 16%, whereas 24% have a negative exploration. CT (72%) and colonoscopy (62%) are more commonly able to diagnose the entity. The most common location of intussusception is the transverse colon (28%). The surgical operation varies according to the site. The average dimensions of the lipoma are 59.81 × 47.84 × 38.9 mm3. CONCLUSIONS: A correct preoperative diagnosis of colonic lipoma causing intussusception might not be easy. Despite nonspecific clinical and laboratory presentation, cross-sectional imaging can help differential diagnosis. Surgical treatment depends on the localization.

Colo-colic intussusception secondary to colon lipoma: A case report.

INTRODUCTION AND IMPORTANCE: Intestinal intussusception is rare in adults and it is associated with lead points affecting the colon in around 17% of patients. Lipomas are very rare benign tumors which may act as lead points for intestinal intussusception. Indeed, the incidence of intestinal intussusception is much rare when caused by lipomas. CASE PRESENTATION: Our patient is a 29-year-old male, previously healthy and admitted for severe right lower quadrant abdominal pain of 2-day duration. Computed tomography (CT) scan of the abdomen and pelvis showed large mass of fat consistency containing colon structure. CLINICAL DISCUSSION: Urgent laparotomy was opted during which colo-colic intussusception was diagnosed and right hemicolectomy with primary ileocolic anastomosis was performed. Pathology report showed that intussusception was induced by a colon lipoma. Patient had an uneventful hospital stay and was discharged on post-operative day 5. CONCLUSION: Thus we recommend that colo-colic intussusception caused by lipoma be considered in the differential when diagnosing adults with right lower quadrant pain.

Undesirable Outcomes from Liposuction of the Calves and Ankles, what to Avoid?

INTRODUCTION: Liposuction, is amongst the most popular cosmetic surgical procedures worldwide and is pretty safe with a very low incidence of major complications in the hands of skilled plastic surgeons. As a matter of fact, a faultless liposuction of the calves and ankles is near the top of the list in providing a high satisfaction rate. AIM: We present a case of 38-year old female with severe complication from liposuction of the thighs, calves and ankles with dimples and contour irregularity. RESULTS: The results were very bad aesthetically with over correction liposuction of the calves and a lot of contour surface irregularity, asymmetry, dimples and grooves. We recommended her several procedures of autologous fat grafting in the calves, to improve the contour irregularities, and the patient agreed to it. CONCLUSION: The surgeon should be very cautious in examining the patient in details to see if liposuction of the calves and ankles is the proper procedure to address their interest. Several times it is required to combine different refinement techniques to achieve patients' aesthetic requests and enhance their appearance.

Adult colocolic intussusception and literature review.

Intussusception occurs when a proximal segment of the gastrointestinal tract, called intussusceptum, telescopes into the lumen of an adjacent segment, also known as intussuscipiens. Although common in early childhood, intussusceptions are very rare in the adult population. Most intussusceptions in adults are due to a lead point, which is an identifiable pathological abnormality, in opposition to children which there are no identifiable pathological lead points. In contrast to childhood intussusception, in adults it is associated with malignant lesions, particularly in the large bowel rather than in the small bowel. Its preoperative diagnosis and treatment in adults is difficult because of nonspecific abdominal symptom and because it rarely presents with the classic triad of vomiting, abdominal pain and passage of blood per rectum. We present a 63-year-old female with an adenocarcinoma tumor being the lead point in a colocolic intussusception, who was diagnosed preoperatively with computed tomography and had a colonoscopy to rule out obstruction. She underwent right hemicolectomy with side-to-side ileocolic anastomosis and did well postoperatively. In addition, we also review the literature and discuss the value of radiological modalities, location and surgical management to try to improve the preoperative diagnosis. Computed tomography scanning with intravenous contrast is maybe the most accurate modality for diagnosis of intussusceptions in adults, and treatment is usually surgical resection without reduction, since most of the colonic lesions are malignant.
