Differences in Clinical Findings Based on the Duration of Symptoms and Age of Children With Ileocolic Intussusception: A Single-Institution Survey in Rural Japan.

OBJECTIVES: The objective of this study was to determine whether the rates of abdominal pain or irritability, vomiting, and hematochezia differ depending on the duration of symptoms and age of the children with ileocolic intussusception. METHODS: We retrospectively investigated the charts of ileocolic intussusception children between January 2008 and December 2017 at a rural general hospital in Japan. Children were separated into 2 groups: the early visiting group, including children examined within 6 hours after onset, and the late visiting group, including children examined more than 6 hours after onset. We further separated them into 2 groups based on age: the infant group (age, <18 months) and the child group (age, ≥18 months). We compared clinical features, such as abdominal pain or irritability, vomiting, and hematochezia, between each group. RESULTS: Among 105 children with ileocolic intussusception, 51 were in the early visiting group and 49 were in the infant group. Hematochezia less frequently occurred in the early visiting group than in the late visiting group (29% vs 50%, P = 0.046). Furthermore, abdominal pain or irritability occurred less frequently in the infant group than in the child group (79.6% vs 98.2%, P = 0.003). Conversely, vomiting and hematochezia were more frequent in the infant group than in the child group (83.7% vs 51.8%, P < 0.001; 55.1% vs 26.8%, P = 0.005). CONCLUSIONS: Clinical features of pediatric ileocolic intussusception may depend on symptom duration and age.

Comparison Between Small and Large Bowel Intussusception in Children: The Experience of a Large Tertiary Care Pediatric Hospital.

BACKGROUND: Intussusception is the most common cause of intestinal obstruction in young children, and delayed diagnosis may lead to serious sequelae. The objective of this study was to determine the prevalence of ileoileal intussusception and to document and compare clinical outcomes with ileocolic intussusception. METHODS: A retrospective cohort study of children with an abdominal ultrasound that diagnosed intussusception. Clinical data and diagnostic studies were retrieved, to compare ileoileal with ileocolic intussusception. RESULTS: A total of 488 patients were evaluated with an abdominal ultrasound on suspicion of intussusception; 54 (11%) had ileoileal intussusception and 30 (6%) ileocolic intussusception. The significant features distinguishing the 2 conditions were fever, more common in patients with ileoileal intussusception, and an abdominal mass, which was papable more commonly in ileocolic intussusception. None of the ileoileal intussusception patients required surgical intervention, and all were discharged without complication. CONCLUSIONS: With recent advances in abdominal ultrasound, the diagnosis of ileoileal intussusception has become easier than before. Patients presenting with small bowel intussusception may not need any immediate intervention. The presence of fever supports the diagnosis of ileoileal intussusception.

Epidemiology study of pediatric primary intussusception aged ≤24 months in pre-rotavirus vaccine era of Jinan, China.

INTRODUCTION: Few studies have reported on the epidemiological characteristics of pediatric primary intussusception in the pre-rotavirus vaccine era of China. It is important to complementary baseline data before rotavirus vaccine introduction in China. This study conduct a retrospective investigation and evaluated the incidence rate, described the epidemiology of pediatric primary intussusception aged ≤24 months. METHODS: We conducted a retrospective investigation in all secondary- and tertiary-hospitals in Jinan. Pediatric primary intussusception inpatients aged ≤24 months were identified depending on ICD-10 discharge code from a total of 63 hospitals from 2011 to 2015. Demographic and clinical information were extracting from the electronic clinical record systems. RESULTS: A total of 575 pediatric primary intussusception inpatients were identified with average annual incidence of 86.5 per 100,000. A significantly higher incidence was observed in males (χ2 = 13.8, P < 0.01), in the ≤12 months old age group (χ2 = 19.5, P < 0.01) and from the urban areas (χ2 = 63.31, P < 0.001). No clear seasonality found. Abdominal pain (80.9%) and vomiting (63.3%) were the most frequently reported. Most intussusception cases occurred in ileo-cecum. Over 92% of intussusception cases were diagnosed by ultrasound alone and 77.4% was successfully treated by air enema. 99.7% were cured. The median time of hospitalization was 2 days (range: 0-35 days). CONCLUSION: This retrospective study provides baseline information of incidence, epidemiologyand clinical characteristics of pediatric primary intussusception in Jinan City during 2011-2016 before the introduction of rotavirus vaccine. It will be important for evaluating safety of rotavirus vaccine if it will be introduced to the routine immunization program in China.

Differential risk of disease progression between isolated anastomotic ulcers and mild ileal recurrence after ileocolonic resection in patients with Crohn's disease.

BACKGROUND AND AIMS: It is standard of care to perform ileocolonoscopy within a year of ileocolonic resection for Crohn's disease (CD) and to guide management decisions based on the Rutgeert score (RS). The modified RS subdivides i2 into lesions confined to the anastomosis (i2a) or >5 aphthous lesions in the neoterminal ileum (i2b). There is uncertainty, however, if i2a lesions incur an increased risk of disease recurrence. The primary aim of this study was to compare the rates of endoscopic progression between i2a and i2b when compared with i0-i1. METHODS: This was a retrospective, single-center study including patients with CD who had an ileocolonoscopy ≤12 months after ileocolonic resection with primary anastomosis and who had >1 year of documented clinical follow-up after the index endoscopic evaluation. All consecutive eligible patients between 2004 and 2014 were included in the study. Demographic, disease, and treatment data were collected. Patients with i3 or i4 at index colonoscopy were excluded from further analyses. Outcomes included endoscopic progression and recurrent surgery. For patients with RS of i0 to i2, endoscopic progression was predefined as progression of the RS in subsequent colonoscopies to i3 or i4. Recurrent surgical interventions were defined as re-resection or stricturoplasty of the previous ileocolonic anastomosis. RESULTS: Two hundred seven CD patients (median age, 36 years [interquartile range, 26-48]) had an ileocolonoscopy ≤12 months after ileocolonic resection. At index colonoscopy, 95 patients (45.9%) had an RS of i0, 31 (14.9%) i1, 40 (19.3%) i2a, 25 (12.1%) i2b, 10 (4.8%) i3, and 6 (2.9%) i4. One hundred ninety-one patients had an RS of i0 to i2 and were included in the analyses for recurrent surgery. One hundred forty-nine patients had a second endoscopic evaluation and were included in the analysis for the primary outcome of endoscopic disease progression. Kaplan-Meier analyses were performed and found the hazard ratio (HR) of endoscopic progression to be significantly higher with i2b lesions when compared with i0 or i1 (HR, 6.22; 95% confidence interval [CI], 2.38-16.2; P = .0008). Patients with i2a did not have significantly higher rates of endoscopic progression when compared with i0 or i1 (HR, 2.30; 95% CI, .80-6.66; P = .12). Likewise, patients with i2b lesions had higher risk of needing recurrent surgery when compared with i0 or i1 (HR, 3.64; 95% CI, 1.10-12.1; P = .034), whereas patients with i2a lesions were not found to have a significantly elevated risk of recurrent surgery (HR, 1.43; 95% CI, .35-5.77; P = .62). CONCLUSION: Endoscopic lesions limited to the ileocolonic anastomosis (RS i2a) in patients with CD undergoing colonoscopy within 1 year of their resection were not associated with a significantly higher rate of progression to more severe disease, whereas those in the neoileum (RS i2b) were. Prospective studies are needed to confirm these findings.

Use of Primary Anastomosis With Diverting Ileostomy in Patients With Acute Diverticulitis Requiring Urgent Operative Intervention.

BACKGROUND: Previous studies suggest that urgent colectomy and primary anastomosis with diversion is safe for perforated diverticulitis. Current guidelines support this approach. OBJECTIVE: The purpose of this study was to describe the use of urgent or emergent primary anastomosis with diversion in diverticulitis before the 2014 American Society of Colon and Rectal Surgeons guidelines and compare national outcomes of primary anastomosis with diversion to the Hartmann procedure. DESIGN: This was a national retrospective cohort study. SETTINGS: The study was conducted with a national all-payer US sample from 1998 to 2011. PATIENTS: Patients included those admitted and treated with urgent or emergent colectomy for diverticulitis. Exclusion criteria were age <18 years, concurrent diagnosis of colorectal cancer or IBD, no fecal diversion performed, and operations >24 hours after admission. MAIN OUTCOME MEASURES: In-hospital mortality was measured. RESULTS: A total of 124,198 patients underwent emergent or urgent colectomy for acute diverticulitis; 67,721 underwent concurrent fecal diversion, including 65,084 (96.1%) who underwent end colostomy and 2637 (3.9%) who underwent anastomosis with ileostomy. The rate of primary anastomosis with diverting ileostomy increased from 30 to 60 diverting ileostomy cases per 1000 operative diverticulitis cases in 1998 versus 2011 (incidence rate ratio = 2.04 (95% CI, 1.70-2.50). However, overall use remained low, with >90% of patients undergoing end colostomy. Complication rates were higher (32.1% vs 23.3%; p < 0.001) and in-hospital mortality rates were higher (16.0% vs 6.4%; p < 0.001) for primary anastomosis with diversion patients compared with end colostomy. These findings were consistent on multivariable logistic regression. Other factors that contributed to in-hospital mortality included increasing age, increasing comorbid disease burden, and socioeconomic status. LIMITATIONS: Billing data can be inaccurate or biased because of nonmedically trained professional data entry. Selection bias could have affected the results of this retrospective study. CONCLUSIONS: The use of primary anastomosis with proximal diversion for urgent colectomy in diverticulitis increased over our study period; however, overall use remained low. Poor national outcomes after primary anastomosis with proximal diversion might affect compliance with new guidelines. See Video Abstract at http://links.lww.com/DCR/A600.

Colonic Crohn's Disease Is Associated with Less Aggressive Disease Course Than Ileal or Ileocolonic Disease.

BACKGROUND: The literature on disease characteristics of colonic Crohn's disease (CD) is sparse, especially from Asia, where the burden of inflammatory bowel disease is on the rise. The present study aims to describe the disease characteristics of colonic CD, and compare it with that of ileal/ileocolonic disease. METHODS: This retrospective study included adult patients of CD (diagnosed by standard criteria, follow-up duration > 6 months) on follow-up between August 2004 and January 2016. The disease location was classified by Montreal classification. The data were recorded on demographic characteristics, smoking status, disease phenotype, disease course, treatment received, hospitalization and surgeries. RESULTS: Of 406 CD patients, 123 had colonic [mean age (at onset) 30.4 ± 13.2 years, 59.3% males] and 265 had ileal/ileocolonic disease [mean age (at onset) 32.9 ± 13.8 years, 61.5% males] while 18 patients had isolated upper GI disease. The frequency of inflammatory behavior (B1 phenotype; 61.8 vs. 46.4%, p = 0.003), perianal disease (23.6 vs. 4.5%, p < 0.001), and extra-intestinal manifestation (42.3 vs. 30.2%, p = 0.019) was higher in colonic than ileal/ileocolonic CD. Though not statistically significant, requirement of atleast one course of steroid was lower in colonic CD (72.7 vs. 84.2%, p = 0.098). Although there was no difference in the frequency of hospitalization (30.1 vs. 27.1%, p = 0.45), the overall requirement for surgery was significantly lower in colonic CD (17.1 vs. 26.1%, p = 0.032) and patients with colonic disease had a lower cumulative probability of first surgery in the first 10 years of follow-up [Hazard ratio 0.556 (95% CI 0.313-0.985), p = 0.045]. CONCLUSION: Colonic CD was associated with less aggressive disease behavior and lower requirement of surgery as compared to ileal/ileocolonic CD.

Intussusception among children less than 2years of age: Findings from pre-vaccine introduction surveillance in Pakistan.

BACKGROUND: Rotavirus vaccination introduction in routine immunization is under consideration in Pakistan. Data on the baseline epidemiology of intussusception will inform surveillance strategies for intussusception after rotavirus vaccine introduction in Pakistan. We describe the epidemiology of intussusception-associated hospitalizations among children <2years of age in Karachi, Pakistan. METHODS: We conducted a retrospective chart review for July 01, 2012 through June 30, 2015 at the National Institute of Child Health (NICH) and Aga Khan University Hospital (AKUH) Karachi. At AKUH, the International Classification of Disease, ninth revision, code 560.0 for intussusception was used to retrieve intussusception case records. At NICH, daily Operation Theater, Emergency Room, and surgical daycare log sheets and surgical ward census sheets were used to identify cases. Records of children who fulfilled eligibility criteria and the Brighton Collaboration level one case definition of intussusception were selected for data analysis. We used structured case report forms to extract data for the descriptive analysis. RESULTS: We identified 158 cases of confirmed intussusception; 30 cases (19%) were from AKUH. More than half (53%) of the cases occurred in children aged 6-12months, followed by 35% among those aged <6months. Two-thirds (106/158) of the cases were male. The most common presenting complaints were vomiting and bloody stool. At NICH, almost all (93%) were managed surgically, while at AKUH, ∼57% of the cases were managed with enemas. Three deaths occurred, all from NICH. Cases occurred without any seasonality. At NICH, 4% (128/3618) of surgical admissions among children aged <2years were attributed to intussusception, while that for AKUH was 2% (30/1702). CONCLUSION: In this chart review, intussusception predominantly affected children 0-6months of age and occurred more commonly in males. This information on the baseline epidemiology of intussusception will inform post-vaccine introduction adverse event monitoring related to intussusception in Pakistan.

Intestinal perforation in the premature infant.

OBJECTIVE: To compare demographic data, prenatal and postnatal characteristics, laboratory data, and outcomes in a cohort of premature infants with spontaneous ileal perforation (SIP), surgical necrotizing enterocolitis (sNEC) and matched controls. METHODS: A retrospective case-control study of infants with intestinal perforation with a birth weight (BW) less than 2,000 grams and gestational age (GA) less than 34 weeks and infants without perforation matched for BW (±150 grams) and GA (±1week). RESULTS: 130 premature infants were included, 30 infants with SIP, 35 infants with sNEC and 65 control infants. The median age of onset was 5 days postnatal age in SIP versus 25 days in sNEC (p < 0.001) and the peak onset was at 26 weeks corrected GA for SIP and 30 weeks corrected GA for sNEC. Infants with perforation had significantly higher rates of mortality (p < 0.001) and common morbidities associated with prematurity. Administration of corticosteroids and indomethacin did not differ among groups. SIP was more common among infants born to young mothers (p = 0.04) and less common in infants receiving caffeine (p = 0.02). sNEC was less common among infants receiving early red cell transfusion (p = 0.01). Perforation and sNEC trended towards less common in infants receiving inhaled nitric oxide. CONCLUSION: SIP and sNEC are distinct clinical entities. Potential protective effects of caffeine, inhaled nitric oxide, and early transfusion should be further studied.

Ileocolonoscopic findings in patients with ankylosing spondylitis: a single center retrospective study.

BACKGROUND/AIMS: In some Western countries, up to 50% of patients with ankylosing spondylitis (AS) have subclinical gut inflammation. This study was conducted to evaluate the prevalence and severity of gut inflammation and to determine clinical factors associated with colonic inflammation in Korean AS patients who performed ileocolonoscopy without evidence of established inf lammatory bowel diseases before. METHODS: One hundred and eight AS patients who underwent ileocolonoscopy were included in this study. Patients were divided into two groups based on gross ileocolonoscopic findings; patients with inflammatory lesions, and patients without inflammatory lesions. RESULTS: Inf lammatory lesions in ileocolonoscopic findings were found in 40 patients. The Ankylosing Spondylitis Disease Activity Score C-reactive protein was higher in the group with inflammatory lesions and gut lesions were found often in the terminal ileum. The risk of inflammatory lesions was higher for AS patients whose symptoms required ileocolonoscopy than for AS patients who underwent routine ileocolonoscopy screening (odds ratio, 3.96). However, abnormal lesions were detected also in 17.6% of the patients who underwent ileocolonoscopy for routine screening and most of them were erosion and ulcer. Among patients with inflammatory lesions (n = 40), 23 showed subclinical gut inflammation associated with AS and 17 were diagnosed finally as Crohn's disease (n = 12), intestinal tuberculosis (n = 4), and ulcerative colitis (n = 1). CONCLUSIONS: Our findings suggest that ileocolonoscopy might be recommended regularly in AS patients even without gastrointestinal symptoms, especially in the patients with high AS activity.

Incidence of and Risk Factors for Free Bowel Perforation in Patients with Crohn's Disease.

BACKGROUND: Incidence of and risk factors for intestinal free perforation (FP) in patients with Crohn's disease (CD) are not established. AIM: To establish rate of and risk factors for FP in a large cohort of CD patients. METHODS: Medical records of CD patients who visited Asan Medical Center from June 1989 to December 2012 were reviewed. After matching the FP patients to controls (1:4) by gender, year, and age at CD diagnosis, and disease location, their clinical characteristics were compared using conditional logistic regression analysis. RESULTS: Among 2043 patients who were included in our study cohort, 44 patients (2.15%) developed FP over a median follow-up period of 79.8 months (interquartile range 37.3-124.6), with an incidence of 3.18 per 1000 person-years [95% confidence interval (CI) 2.37-4.28]. All 44 patients underwent emergency surgery, and eight patients underwent reoperation within 12 months (8/44, 18.2%). Multivariable-adjusted analysis revealed that anti-TNF therapy [odds ratio (OR), 3.73; 95% CI 1.19-11.69; p = 0.024] was associated with an increased risk of FP. CONCLUSIONS: The incidence of FP in a large cohort of Korean CD patients was 2.15%, which was similar to that in Western reports. Anti-TNF therapy could be risk factors for FP.

Distal intestinal obstruction syndrome and colonic pathologies in cystic fibrosis.

The management of abdominal pain in cystic fibrosis can be complicated. Distal intestinal obstruction syndrome is a common cause of pain and obstruction in these patients. Knowledge of the diagnosis and management and of similar presenting symptoms is essential for the hospital doctor.

Ileo-sigmoid knotting: a review of 61 cases in Kenya.

INTRODUCTION: Ileo-sigmoid knotting (ISK) is a rare cause of bowel obstruction in which the ileum twists around the sigmoid colon. It is associated with rapid bowel gangrene and a high mortality rate. Little has been published about this condition in Kenya. The objective was to determine the presentation, management, and outcome of patients with ISK. METHODS: A seven year (January 2008-December 2014) retrospective chart review of patients managed for ISK at Tenwek Hospital in Bomet, Kenya. RESULTS: A total of 61 cases were identified, with a mean age of 35.8 years (range 2-68), and mean symptom duration of 1.6 days (range 3 hours-7 days). Gangrene was noted to involve both the ileum and colon in 45 patients, the ileum only in 9 patients, and the sigmoid colon only in one. Resection and primary anastomosis was carried out in most cases of gangrenous ileum (48/54, 89%) and gangrenous sigmoid colon (34/46, 74%), while resection and stoma was performed in 8 patients with gangrenous colon. Death occurred in 7 (11.5%) patients due to severe sepsis and multisystem organ failure. Morbidities were noted in 15 (24.6%) patients, including surgical site infection (8, 13.1%), respiratory insufficiency (4, 6.6%), fascial dehiscence (3, 4.9%) and anastomotic leak (2, 3.2%). The mean duration of hospitalization was 8.3 days (range 1-26). CONCLUSION: In this review, though retrospective in nature, ISK was noted to have high rates of bowel gangrene. In the appropriate setting, resection and primary anastomosis can be safely carried out in most cases of gangrenous colon.

PATTERNS AND SEASONAL VARIATION OF INTUSSUSCEPTION IN CHILDREN: A RETROSPECTIVE ANALYSIS OF CASES OPERATED IN A TERTIARY HOSPITAL IN ETHIOPIA.

BACKGROUND: Intussusception is one of the frequent causes of bowel obstruction in infants and toddlers (1). It involves invagination of a portion of intestine into another(2-4). The peak age of occurrence is between the age of 4 and 8 months. The aim of this study is to review the pattern of clinical presentation and seasonal variation of intussusception in our hospital, and to analyze the mode and outcomes of treatment. PATIENTS AND METHODS: This is a four-year retrospective study of children aged 13 years and below who were admitted and treated for intussusception between January 2011 and December 2014 at the pediatric surgery unit of Tikur Anbesa Specialized Hospital (TAH) in Ethiopia. Information on the patients' demographic characteristics, clinical presentation, and month of occurrence as well as the operative findings and outcome were obtained from the pediatric surgery unit record book, patient charts, and the operating theatre registry. RESULTS: One hundred and thirty six cases of intussusception were admitted to TAH, Addis Ababa over a four year period, of which 130 charts were retrieved and analyzed. Males dominated in the series. Age distribution showed that 59.2% of the cases were ≤ one year old, and 77.7 % were ≤ two years old. Abdominal pain, vomiting, bloody mucoid diarrhea and a mass palpated abdominally and/or rectally were the most common modes of presentations, with the classic triad of abdominal pain, vomiting and bloody mucoid diarrhea occurring in nearly two third of cases. The highest peak of presentation was in the month of June with 18 (13.9%) cases. The mean duration of symptoms before presentation to our hospital was 5.2 days with a range of 1-21 days. Intraoperatively, it was found that ileocolic intussusception was the most common type. Simple reduction without bowel resection was possible in 70.8% of cases. There were 44 (33.9 %) complications, wound site infection being the most common occurring in 20 (15.4%) cases and there were 6 deaths. CONCLUSION: Intussusception was more common in the wet season. There was delayed presentation with a higher rate of operative management and bowel resection. The mortality rate has decreased significantly compared with a previous study from this institution.

Is every intussusception treatment an emergency intervention or surgery?

BACKGROUND: Intussusception is the second most common cause of acute abdomen in children, following appendicitis. The aim of the present study was to evaluate the experience of the authors, in an effort to promote intussusception management, especially that of small bowel intussusception. METHODS: Records of intussusception diagnosed between July 2002 and September 2014 were evaluated in terms of patient age, sex, clinical findings, admission time, ultrasonographic findings, treatment methods, and outcomes. RESULTS: Eighty-one patients, 52 males and 29 females, were included (mean age: 10.6 months). Intussusceptions were ileocolic (IC) in 52 cases, ileoileal (IL) in 26, and jejunojejunal (JJ) in 3. Nineteen (23.5%) patients underwent surgery. Hydrostatic reduction was performed in 45 (55.5%) IC cases. Seventeen (21%) patients with small bowel intussusceptions (SBIs), measuring 1.8-2.3 cm in length, spontaneously reduced. All patients who underwent surgery had intussusceptums ≥4 cm. Three of the 4 intestinal resection cases had history of abdominal surgery. CONCLUSION: If peritoneal irritation is present, patients with intussusception must undergo surgery. Otherwise, in patients with IC intussusception and no sign of peritoneal irritation, hydrostatic or pneumatic reduction is indicated. When this fails, surgery is the next step. SBIs free of peritoneal irritation and shorter than 2.3 cm tend to spontaneously reduce. For those longer than 4 cm, particularly in patients with history of abdominal surgery, spontaneous reduction is unlikely.

Childhood intussusception: Impact of delay in presentation in a developing country.

BACKGROUND: The classical cases of intussusception are readily diagnosed clinically, and despite recent improvements in radiological techniques, the diagnosis of intussusception and success in its nonoperative reduction has been suboptimal, thus making operative management a veritable backup. This study examined the impact of delays in presentation on the rate of bowel resection, length of hospital stay, and appraised the outcome of operative treatment. PATIENTS AND METHODS: This was a retrospective study of consecutive children admitted and treated surgically for intussusception between January 2002 and December 2011 at the University College Hospital, Ibadan, Nigeria. RESULTS: The mean age at presentation was 13.4 months with a male: female ratio of 1.8:1. Fourteen patients (25.5%) presented within the first 24 h of onset of symptoms with majority (36.4%) presenting between 2 and 3 days of onset of symptoms. The primary surgical intervention was performed on 47 patients (85.5%), and the secondary operative intervention was performed on eight patients (14.5%) who had failed initial nonoperative management of intussusception. Manual reduction of intussusception was performed on 27 patients (49.1%), 26 patients had resection of gangrenous bowel with end-to-end anastomosis while two patients (3.6%) had spontaneous reduction of intussusception which was discovered at laparotomy. The mean duration of hospital stay was 12.1 days (range 3-60 days). The overall mortality was 5.5% (three patients), and three patients (5.5%) had recurrence of intussusception. CONCLUSION: Although mortality is reducing, a high rate of bowel resection is a consequence of delayed presentation and effort should be made to make an early diagnosis of intussusception and make prompt referral to improve outcome.

Typhoid perforation: Post-operative Intensive Care Unit care and outcome.

BACKGROUND: Typhoid perforation ileitis is a serious complication of typhoid fever, a common and unfortunate health problem in a resource-poor country like Nigeria. Following bowel perforation, treatment is usually by simple closure or bowel resection and anastomosis after adequate aggressive fluid resuscitation and electrolyte correction. Postoperatively, some of these patients do require management in Intensive Care Unit (ICU) on account of sepsis or septic shock and to improve survival. PATIENTS AND METHODS: This is a prospective observational study in which 67 consecutive patients who had exploratory laparotomy for typhoid perforation between August 2009 and October 2012 in the main operating theatre of the University College Hospital, Ibadan, were studied. The attending anaesthetists had the freedom of choosing the appropriate anaesthetic drugs depending on the patients' clinical condition. The reason for admission into the ICU, the types of organ support required and outcomes were recorded. RESULTS: Twenty-five patients (37.3%) out of 67 required critical care. Reasons for admission among others included poor respiratory effort, hypotension, septic shock and delayed recovery from anaesthesia. Twenty-one patients (84%) required mechanical ventilation with a mean duration of 2.14 days (range 1-5 days). Fourteen patients required ionotropic support and the length of ICU stay ranged from 1 to 15 days (mean 4.32 days). Nineteen patients (76%) were successfully managed and discharged to the ward while 24% (6 patients) mortality rate was recorded. CONCLUSION: This study showed high rate of post-operative ICU admission in patients with typhoid perforation with a high demand for critical care involving mechanical ventilation and ionotropic support. In centres that manage patients presenting with typhoid ileitis and perforation, post-operative critical care should be available.

Childhood intussusception: A prospective study of management trend in a developing country.

BACKGROUND: The management of intussusception has evolved universally from the use of hydrostatic reduction through operative reduction to the use of pneumatic reduction for the acute and uncomplicated cases and surgical reduction for the complicated cases. However, the process of evolution has been very slow in the developing countries, especially sub-Saharan Africa, due to lack of requisite facilities and expertise to manage these patients nonoperatively. This study examined the trends in the management of childhood intussusception in a developing country, compared operative and nonoperative modalities of treatment, and assessed the impact of delayed presentation on the outcome of management. PATIENTS AND METHODS: This was a prospective study of the management of children with intussusception at the University College Hospital, Ibadan, Nigeria. RESULTS: Fifty-five consecutive cases of intussusception that presented to the Children Emergency Unit of the University College Hospital between January 2005 and December 2011 were prospectively studied. Details of sex, age of the patients, clinical presentation, duration of symptoms, mode of treatment, and incidence of recurrence were recorded and analyzed. The median age was 7 months. Moreover, the duration of symptoms varied from 1 to 21 days with a mean of 4 days. Twenty-two patients (40%) had attempted hydrostatic reduction; this was successful in 14 patients (63.6%), whereas 8 patients (36.4%) had failed reduction. In all, 41 patients (74.6%) had operative management of intussusceptions; primary operative intervention was carried out in 33 patients (60%) and secondary surgical management in 8 patients (14.5%) with failed hydrostatic reduction. At surgery, manual reduction of intussusception was carried out on 17 patients (30.9%) and resection of devitalized bowel with end to end anastomosis was carried out on the remaining 24 patients (43.6%). The incidence of surgical intervention for intussusception was 74.6%, mortality was 3.6%, and recurrence rate was 3.6%. CONCLUSIONS: Nonoperative management of intussusception should be adopted in carefully selected cases of intussusception in this subregion as it will help to reduce the financial burden on the parents while surgical management should be reserved for the complicated cases.

Characteristics of Pediatric Inflammatory Bowel Disease in Korea: Comparison with EUROKIDS Data.

BACKGROUND/AIMS: Pediatric inflammatory bowel disease (IBD) has been increasing worldwide. The characteristics of pediatric-onset IBD have mainly been reported in Western countries. We investigated the clinical characteristics of pediatric IBD in Korea and compared these with the data from the 5-year European multicenter study of children with new-onset IBD (EUROKIDS registry). METHODS: Children who were diagnosed with IBD between July 1987 and January 2012 were investigated at five Korean university hospitals. Their clinical characteristics were retrospectively evaluated by medical record review. The results were compared with the EUROKIDS data. RESULTS: A total of 30 children with Crohn's disease (CD) and 33 children with ulcerative colitis (UC) were enrolled. In comparison with the EUROKIDS group, Korean pediatric IBD patients showed a male predominance (86.7% vs 59.2%, p=0.002 in CD; 75.8% vs 50%, p=0.003 in UC). Korean pediatric CD patients had a higher prevalence of terminal ileal disease (36.7% vs 16.3%, p=0.004) and perianal disease (33.3% vs 8.2%, p<0.001) than patients in the EUROKIDS group. Korean pediatric UC patients had a higher prevalence of proctitis than patients in the EUROKIDS group. CONCLUSIONS: Our results suggest that the characteristics of Korean pediatric IBD patients and European pediatric IBD patients may be different.

Intussusception in infants--storm from a clear sky.

Intussusception is one of the most common causes of acute abdominal conditions requiring surgical therapy in infants and babies. Due to the breakthroughs of pediatric intensive care and imaging methods, which may sometimes replace therapeutic methods, this condition, which used to be associated with high morbidity and mortality rates, is now more easily detected and treated immediately, even by non-surgical means. Nevertheless, there still is a high percent of cases in whom the diagnosis is set relatively late and who require laborious surgical procedures and extensive intestinal resections. These cases have high morbidity rates, the condition sometimes has a negative course and the patients die. We conducted an analytical retrospective study on a group of 49 patients diagnosed with intussusceptions, hospitalized and treated in the Pediatric Surgery Ward of the Children's Hospital of Iasi City during 5 years. Although the demographics and clinical presentation of our patients is largely in agreement with literature data, we note that 69.4% of the patients came to the hospital 24 hours after the onset of their symptoms, which delayed diagnosis setting, ruled out non-surgical therapy and thus led to a high rate of postoperative complications (24.5%) and also to a high mortality rate (6.6%).

The clinical characteristics of patients with free perforation in Korean Crohn's disease: results from the CONNECT study.

BACKGROUND: Free perforation is the most severe and debilitating complication associated with Crohn's disease (CD), and it usually requires emergency surgery. The aim of this study was to evaluate the incidence of free perforation among Korean patients with CD. METHODS: The CrOhn's disease cliNical NEtwork and CohorT (CONNECT) study was conducted nationwide in Korea, and patients who were diagnosed with CD between 1982 and 2008 were included in this retrospective study. We investigated the incidence of free perforation among these patients and their clinical characteristics. RESULTS: A total of 1346 patients were analyzed and 88 patients (6.5%) were identified with free perforation in CD. The mean age of the free perforation group was 31.8 ± 13.0 years, which was significantly higher than that of the non-perforated group (27.5 ± 12.1 years) (p = 0.004). Free perforation was the presenting sign of CD in 46 patients (52%). Of the 94 perforations that were present in 88 patients, 81 involved the ileum. Multivariate logistic regression analysis determined that free perforation was significantly associated with being aged ≥ 30 years at diagnosis (OR 2.082, p = 0.002) and bowel strictures (OR 1.982, p = 0.004). The mortality rate in the free perforation group was significantly higher (4.5%) than that in the non-perforated group (0.6%) (p < 0.001). CONCLUSION: The incidence of free perforation in Korean patients with CD was 6.5%. Being aged ≥ 30 years at CD diagnosis and bowel strictures were significant risk factors associated with free perforation.
