Acute abdominal pain is a common complaint in children. The care of these patients is challenging for clinicians because presentation, diagnosis, and treatment are different in children than adults. This article describes the presentation, physical examination, diagnosis, and treatment of common causes of acute abdominal pain in children and discusses emerging trends in diagnosis and treatment.

Intussusception is defined as the invagination of one segment of the bowel into an immediately adjacent segment of the bowel. Idiopathic ileocolic intussusception is the most common form in children and is typically managed with nonoperative reduction via pneumatic and/or hydrostatic enemas. In the adult population, intussusception is uncommon and occurs more often in the small intestine than in the colon. It is associated with lead point pathology in most symptomatic cases presenting as bowel obstruction. When lead point pathology is present in adult small bowel intussusception, it is usually benign, though when malignant it is most frequently due to diffuse metastatic disease, for example, melanoma. In contrast, adult ileocolic and colonic intussusception lead point pathology is most frequently primary adenocarcinoma when malignant. The diagnosis is typically made intraoperatively or by cross-sectional imaging. With increasingly frequent CT/MRI of the adult abdomen in the current era, transient and/or asymptomatic intussusceptions are increasingly found and may often be appropriately observed without intervention. When intervention in the adult population is warranted, usually oncologic bowel resection is performed due to the association with lead point pathology.

Article first published online 9 February 2015., Surgical management of inflammatory bowel disease is a challenging endeavor given infectious and inflammatory complications, such as fistula, and abscess, complex often postoperative anatomy, including adhesive disease from previous open operations. Patients with Crohn's disease and ulcerative colitis also bring to the table the burden of their chronic illness with anemia, malnutrition, and immunosuppression, all common and contributing independently as risk factors for increased surgical morbidity in this high-risk population. However, to reduce the physical trauma of surgery, technologic advances and worldwide experience with minimally invasive surgery have allowed laparoscopic management of patients to become standard of care, with significant short- and long-term patient benefits compared with the open approach. In this review, we will describe the current state-of the-art for minimally invasive surgery for inflammatory bowel disease and the caveats inherent with this practice in this complex patient population. Also, we will review the applicability of current and future trends in minimally invasive surgical technique, such as laparoscopic “incisionless,” single-incision laparoscopic surgery (SILS), robotic-assisted, and other techniques for the patient with inflammatory bowel disease. There can be no doubt that minimally invasive surgery has been proven to decrease the short- and long-term burden of surgery of these chronic illnesses and represents high-value care for both patient and society.

ObjectivesOur aim was to conduct a systematic review of the literature to determine the impact of patient decision aids (PDA) on patients facing treatment decisions for colorectal cancer.DesignSystematic review.Data sourcesSources included Embase, Medline, Web of Science, CINAHL and the Cochrane Library from inception to June, 20, 2019.Eligibility criteriaWe included randomised controlled trials (RCTs), cohort studies, mixed methods and case series in which a PDA for colorectal cancer treatment was used. Qualitative studies were excluded from our review.Data extraction and synthesisFollowing execution of the search strategy by a medical librarian, two blinded independent reviewers identified articles for inclusion. Two blinded reviewers were also responsible for data extraction, risk of bias and study quality assessments. Any conflict in article inclusion or extraction was resolved by discussion.ResultsOut of 3773 articles identified, three met our inclusion criteria: one RCT, one before-and-after study and one mixed-method study. In these studies, the use of a PDA for colorectal cancer treatment was associated with increased patient knowledge, satisfaction and preparation for making a decision. On quality assessment, two of three studies were judged to be of low quality.ConclusionA paucity of evidence exists on the effect of PDA for colorectal cancer treatment with existing evidence being largely of low quality. Further investigation is required to determine the effect of decision aids for colorectal cancer treatment as well as reasons for the lack of PDA development and implementation in this area.Prospero registration numberCRD42018095153.

Although it is commonly reported that IBD patients are at increased risk for venous thromboembolic events, little real-world data exist regarding their postoperative incidence and related outcomes in everyday practice.We aimed to identify the rate of venous thromboembolism and modifiable risk factors within a large cohort of surgical IBD patients.We performed a retrospective review of IBD patients who underwent colorectal procedures.Patient data were obtained from the American College of Surgeons National Surgical Quality Improvement Program 2004 to 2010 Participant Use Data Files.The primary outcomes measured were short-term (30-day) postoperative venous thromboembolism (deep vein thrombosis and pulmonary embolism). Clinical variables were analyzed by univariate and multivariate analyses to identify modifiable risk factors for these events.A total of 10,431 operations were for Crohn's disease (52.1%) or ulcerative colitis (47.9%), and 242 (2.3%) venous thromboembolic events occurred (178 deep vein thromboses, 46 pulmonary embolisms, 18 both) for a combined rate of 1.4% in Crohn's disease and 3.3% in ulcerative colitis. Deep vein thrombosis and pulmonary embolism each occurred at a mean of 10.8 days postoperatively (range for each, 0-30 days). A multivariate model found that bleeding disorder, steroid use, anesthesia time, emergency surgery, hematocrit37%,malnutrition, and functional status were potentially modifiable risk factors that remained associated (p0.05) with venous thromboembolism on regression analysis. Patients with thromboembolism had longer length of stay (18.8 vs 8.9 days), more complications (41% vs 18%), and a higher risk of death (4% vs 0.9%).This study was limited by its retrospective design and its limited generalizability to nonparticipating hospitals.Inflammatory bowel disease patients are at increased risk for postoperative venous thromboembolism. Reducing preoperative anemia, steroid use, malnutrition, and anesthesia time may also reduce venous thromboembolism in this at-risk population. Risk-reducing, preventative strategies are needed in this at-risk population.
