Objective The study evaluated factors associated with abdominal pain during colonoscopy. Methods This was a cross-sectional observational study that evaluated patients who underwent colonoscopy between February 2014 and February 2015. Physical characteristics, surgical history and previous colonoscopies, indication and current examination conditions, fentanyl and midazolam dose, and pain level were analyzed. Significance level adopted: p < 0.05. Chi-squared test was used for association of categorical variables, Student's t-test was applied for comparison of means, and Spearman's coefficient was used for correlation. Results A total of 566 women and 391 men with mean age of 54.81 years and mean BMI of 27,064 were evaluated. Of the total, 29 (3.0%) had mild pain, 42 (4.4%) had moderate pain, and 18 (1.9%) had severe pain. Women were less tolerant (p = 0.011) and had longer cecal intubation times (p = 0.001). Mean duration of colonoscopy and mean dose of midazolam were higher in patients with pain (p = 0.001), (p < 0.001*). Among the 39 patients with an incomplete examination, 8 reported pain (p = 0.049). Conclusion Female gender and prolonged intubation time were significantly associated with abdominal pain during colonoscopy. Patients with discomfort had a higher failure rate on the exam. Additional doses of midazolam given to patients with pain were not effective.

Case report of three patients with inflammatory bowel disease who underwent treatment with biology therapy and developed respectively: non-Hodgkins lymphoma, colorectal adenocarcinoma, and cholangiocarcinoma after long-term follow-up. They demonstrated that data are currently inconclusive about the development of long-term anti-TNF neoplasias.

The treatment of colorectal diseases by videolaparoscopy (VL) began in the 1990s, bringing multiple advantages in the treatment of cancers in general, especially benign tumors. Specifically, in case of colorectal cancer (CRC), the laparoscopic approach offers very attractive prospects, such as the staging of advanced lesions and palliative management of patients with incurable CCR. The most controversial aspect of this technique is the use of VL in curative resections. One questions the possibility of metastasis in portals related to tumor recurrence, as well as the violation of oncological principles. The mechanisms responsible for this phenomenon may be related to pneumoperitoneum, tissue manipulation, and biological factors.

Arterial puncture, better known as catheterization, has become an important diagnostic tool in recent years. For its realization, generally the option is the Seldinger technique, which is considered today the safest and most often used procedure. This technique allows the insertion of large-caliber or multiple-lumen catheters in the vessel. Arterial catheterization helps in several exams, for instance, mesenteric angiography and cardiac output assessment, and contributes in cineangiocoronariography procedures. We report the case of a 67-year-old male patient who was submitted to cineangiocoronariography and evolved with enterorrhagia due to pelvic hematoma. Throughout the patient's care, a conservative treatment was chosen. The progression of the patient was uneventful and then the patient was discharged. It is very hard to determine which arterial segment was injured; however, as the hematoma was located predominantly in the pelvic region, it is believed that an injury occurred at the internal iliac artery, or directly at the bifurcation of the common iliac artery. Furthermore, it is assumed that a catheter kinking occurred during its progression, due to any tortuosity or to the presence of an atheromatous plaque, thus favoring the occurrence of the more distal lesion, rather than the proximal one. We decided to report this case because of its high degree of rarity, with a scarce number of papers in the literature related to the topic. Thus, with the description of this report we believe that other medical teams will have facilitated their decision-making process, when facing a similar case.
