Introduction Ingestion of foreign bodies implies a 35% risk of possible complications, which are associated with their type (blunt or sharp) and their size. Although in most of them, it is expected that they pass along the gastrointestinal tract without difficulty or complications, the management will depend on the characteristics of the swallowed object, time of evolution and symptoms of the patient. Case description We present the clinical case of a 58-year-old female patient with a recent gastric bypass surgical history, who accidentally ingested a piece of dental equipment two months earlier during a dental procedure, remaining asymptomatic until she came to our office. In radiographic controls for confirmation, location and evolution, the presence of a 2 cm sharp object was evidenced, apparently located in the cecal appendix, which does not progress distally. For the management, initial expectant management was proposed, which was completed with therapeutic colonoscopy for its extraction, the technique recommends that the sharp object should be grasped by the pointed end, distal to the wall, which reduces the risk of perforation related to the procedure or damage of the mucosa during extraction, the case is completed with successful resolution and without complications. Conclusion Less invasive therapeutic management such as colonoscopy should be considered first line in this type of case, when there are no signs or radiological findings of perforation or clinical instability, due to its low incidence of complications and a high success rate.

In large bowel investigations using endoscopic capsules and upon detection of significant findings, physicians require the location of those findings for a follow-up therapeutic colonoscopy. To cater to this need, we propose a model based on tracking feature points in consecutive frames of videos retrieved from colon capsule endoscopy investigations. By locally approximating the colon as a cylinder, we obtained both the displacement and the orientation of the capsule using geometrical assumptions and by setting priors on both physical properties of the intestine and the image sample frequency of the endoscopic capsule. Our proposed model tracks a colon capsule endoscope through the large intestine for different prior selections. A discussion on validating the findings in terms of intra and inter capsule and expert panel validation is provided. The performance of the model is evaluated based on the average difference in multiple reconstructed capsule’s paths through the large intestine. The path difference averaged over all videos was as low as 4±0.7 cm, with min and max error corresponding to 1.2 and 6.0 cm, respectively. The inter comparison addresses frame classification for the rectum, descending and sigmoid, splenic flexure, transverse, hepatic, and ascending, with an average accuracy of 86%.

S100 proteins are involved in the pathogenesis of sporadic colorectal carcinoma through different mechanisms. The aim of our study was to assess tissue mRNA encoding S100 proteins in patients with non-advanced and advanced colorectal adenoma. Mucosal biopsies were taken from the caecum, transverse colon and rectum during diagnostic and/or therapeutic colonoscopy. Another biopsy was obtained from adenomatous tissue in the advanced adenoma group. The tissue mRNA for each S100 protein (S100A4, S100A6, S100A8, S100A9, S100A11 and S100P) was investigated. Eighteen biopsies were obtained from the healthy mucosa in controls and the non-advanced adenoma group (six individuals in each group) and thirty biopsies in the advanced adenoma group (ten patients). Nine biopsies were obtained from advanced adenoma tissue (9/10 patients). Significant differences in mRNA investigated in the healthy mucosa were identified between (1) controls and the advanced adenoma group for S100A6 (p = 0.012), (2) controls and the non-advanced adenoma group for S100A8 (p = 0.033) and (3) controls and the advanced adenoma group for S100A11 (p = 0.005). In the advanced adenoma group, differences between the healthy mucosa and adenomatous tissue were found in S100A6 (p = 0.002), S100A8 (p = 0.002), S100A9 (p = 0.021) and S100A11 (p = 0.029). Abnormal mRNA expression for different S100 proteins was identified in the pathological adenomatous tissue as well as in the morphologically normal large intestinal mucosa.
