bowel manipulation

Eoin P Cummins, Daniel Crean
Inflammatory bowel disease (IBD) is a general term to describe inflammatory diseases of the gastrointestinal tract such as Crohn's disease and ulcerative colitis. IBD affects approximately 1 in 200 individuals and exerts a significant health and quality of life burden on patients. Surgical intervention can be curative in ulcerative colitis but there is currently no cure for Crohn's disease. Since this is the case, and the fact that patients are often diagnosed at a young age, IBD exerts a significant financial burden on the health care system, and society as a whole...

Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in childhood. The pathogenesis of JIA is thought to be the result of a combination of host genetic and environmental triggers. However, the precise factors that determine one's susceptibility to JIA remain to be unravelled. The microbiome has received increasing attention as a potential contributing factor to the development of a wide array of immune-mediated diseases, including inflammatory bowel disease, type 1 diabetes and rheumatoid arthritis...

Surgical robots in popular clinical use are generally large machines, which limits their practical use to some extent. This study aims to investigate the potential of a small, table-mounted robot for tool guidance in minimally invasive surgery (MIS). In particular, its multipurpose use for guidance of various tools was investigated. A compact robot capable of manipulating MIS tools was designed and built. The robot can move in four degrees of freedom (DOF): three rotational and one translational. These DOF correspond to motion constrained by a trocar...

The control of the conventional flexible endoscope is non-ergonomic and non-intuitive. A novel single-handed interface could reduce the experienced workload, without reducing current efficiency or effectiveness of endoscope manipulation. The aim of this study is to evaluate the workload, efficiency and effectiveness of a single-handed controller in colonoscopy, in comparison to a bimanual controller and the conventional angulation wheels. Twenty-one inexperienced students performed colonoscopies on a computer simulator using either the single-handed controller with a joystick interface, a bimanual controller with a joystick interface or the conventional angulation wheels...

To investigate the development of new technical approaches for improving the implementation of robotics in gynaecologic surgery, we conducted a prospective evaluation of five technical modifications developed during the implementation of a robotics program that included 171 robotic endometrial staging procedures from December 2007 until May 2010. Modification of the use of a Hohl uterine manipulator by applying only the intravaginal component minimizes the theoretical risk of spillage of endometrial cancer cells, without losing the capability of delineating the vaginal fornices...

BACKGROUND: Intestinal failure-associated liver disease causes significant mortality in patients with short bowel syndrome. Steatosis, a major component of intestinal failure-associated liver disease has been shown to persist even after weaning from parenteral nutrition. We sought to determine whether steatosis occurs in our murine model of short bowel syndrome and whether steatosis was affected by manipulation of the intestinal microbiome. METHODS: Male C57BL6 mice underwent 50% small bowel resection and orogastric gavage with vancomycin or vehicle for 10 weeks...

UNLABELLED: The green color in urine may suggest the presence of a severe pathology needing treatment. Many different potential causes of green urine have previously been reported. In our case, after ruling out other potential causes of green urine, it was suggested that the surgical manipulation of the paralytic ileum might have induced the reabsorption of the methylene blue which had been retained in the bowel (bezoar effect), even 96 hours after the nasogastric administration. CONCLUSIONS: The staff should keep in mind this possible effect due to methylene blue to recognize early and avoid unnecessary laboratory tests...

BACKGROUND AND AIMS: Colon capsule endoscopy has become an alternative method to evaluate the colonic mucosa without pain, sedation, and gas insufflation in recent years. The magnetic-controlled capsule endoscopy (MCCE) system is an innovative ingestible colon capsule. We performed a pilot study to assess its maneuverability and safety among subjects who volunteered to undergo colorectal cancer screening. METHODS: Fifty-seven volunteers underwent both MCCE and colonoscopy procedures...

BACKGROUND: Postoperative ileus, a transient impairment of bowel motility initiated by intestinal inflammation, is common after an abdominal operation and leads to increased hospital stays and costs. Hydrogen has potent anti-inflammatory and antioxidant properties and potential therapeutic value. Solubilized hydrogen may be a portable and practical means of administering therapeutic hydrogen gas. We hypothesized that intraperitoneal administration of hydrogen-rich saline would ameliorate postoperative ileus...

This review summarizes the published clinical studies concerning the management of irritable bowel syndrome (IBS) using restriction of Fermentable Oligosaccharide, Disaccharide, Monosaccharide, and Polyols in the diet (low FODMAP diet). In recent years, the data supporting low FODMAP diet for the management of IBS symptoms have emerged, including several randomized controlled trials, case-control studies, and other observational studies. Unlike most dietary manipulations tried in the past to alleviate gastrointestinal symptoms of IBS, all studies on low FODMAP diet have consistently shown symptomatic benefits in the majority of patients with IBS...

The importance of the microbiome in health and disease has galvanized interest in using manipulations of the gastrointestinal ecosystem to prevent and/or combat gut bacterial infections and to restore mucosal homeostasis in patients with generalized microbial imbalances (i.e., dysbiosis), including the human inflammatory bowel diseases, Crohn's disease, and ulcerative colitis. Probiotics, prebiotics, or their combination use (i.e., synbiotics) are one mechanism for modifying the microbiota and exerting direct and indirect effects on the host immune responses and metabolomics profiles...

A number of diseases are associated with alterations in the composition of the microbiota of various niches of the human body. Although, in most cases, it is unclear if these alterations are the cause or the consequence of disease, they provide a rationale for therapeutic or prophylactic manipulation of a dysbiotic microbiota. Approaches to manipulate the microbiome include administration of either live bacteria, which are underrepresented in the diseased individual, substances that aim at increasing the populations of these bacteria, or a combination of the two...

In this article we explore the ethics of manipulating verbal information for the sake of influencing health outcomes through placebo and nocebo responses. Recent scientific research on placebo and nocebo effects has drawn attention to the ways in which communication by health professionals may modulate the symptoms of patients across an array of highly prevalent conditions such as pain, depression, anxiety, insomnia, irritable bowel syndrome, migraine, and Parkinson's disease. The positive and negative effects of clinicians' communication on patient outcomes pose important ethical issues, which we describe in this article under the label of "the ethics of therapeutic communication" (TC)...

BACKGROUND: The extraperitoneal rectal dissection via a transanal approach facilitates the mesorectal dissection. The retroperitoneal approach for mesocolic excision may also offer some similar advantages. To complete the lymphadenectomy of extraperitoneal mesorectal resection, we developed an innovative approach for upper rectal and mesocolic excision via an exclusive retroperitoneal dissection using a single-port access at the site of the future stomy. METHODS: This study was a prospective pilot study and was conducted between 2013 and 2015 at two oncologic centers...

PURPOSE: Gut microbiota is predicted to play a key role in manifestation of gastrointestinal tract cancers. The human gastrointestinal tract is a complex and abundant network of microbial community. Gut microbiota depicts the microbe population living in our intestine. Humans harbour more than 10(14) microbes in the gut, and the diversity and densities of the microbiota increase from stomach to colon. METHODS: The beneficial relationship between endogenous microbiota and the eukaryotic hosts helps in maintaining various metabolic activities of the body as well as temperature and pH balance...
