Background And Aim: Delayed postpolypectomy hemorrhage is relatively common, with occasional extensive blood loss, endangering life. This study aimed to determine the factors associated with postoperative hemorrhage.
Methods: The study was a retrospective cohort study of patients hospitalized for colonoscopic polypectomy at the Department of Gastroenterology and Hepatology, Tenth People's Hospital of Tongji University, China, between January and December 2015. Data on gender, age, bowel preparation, location, size, number of polyps, operative modality, pathology, and operation practitioner were collected. Patients were divided into two groups based on the presence or absence of postoperative hemorrhage.
Results: A total of 1962 polyps were detected in patients and they underwent polypectomy; hemorrhage occurred in 41 cases. A correlation was demonstrated between postpolypectomy hemorrhage and each of the following factors: polyp size and operative modality. The odds ratio (OR) was 4.535 (95% confidence interval [CI], 2.331-8.823) for 1-2-cm polyps, 4.008 (95% CI, 0.904-17.776) for 2-3-cm polyps, and 22.407 (95% CI, 5.783-86.812) for ≥3-cm polyps. Compared with argon plasma coagulation, OR was 9.128 (95% CI, 3.548-23.486) for endoscopic mucosal resection and 31.257 (95% CI, 7.009-139.395) for endoscopic submucosal dissection.
Conclusions: The independent risk factors for delayed postpolypectomy hemorrhage include polyp size and operative modality.

Both the surgical non-cultured melanocyte-keratinocyte transplant procedure (MKTP) and intradermal injection of 5-Fluorouracil (5-FU) are effective in the treatment of vitiligo. Intrablisters injection of MKTP was done in one study with better results than MKTP application after ablative CO2 laser of the reciepient area. However, intrablister injection of 5-FU was not done before.

Knowledge on the effect of different nicotine consumption modalities on dermatologic surgical outcomes is limited, with conflicting conclusions. Cigarette smoking is known to adversely affect outcomes, but the impact of other nicotine consumption modalities like cigars, smokeless tobacco, and nicotine replacement therapy (NRT) is less understood. Our objective was to evaluate the impact of various nicotine consumption modalities on complication rates after Mohs micrographic surgery (MMS).

Background: Multimodal prehabilitation programs are effective at reducing complications after colorectal surgery in patients with a high risk of postoperative complications due to low aerobic capacity and/or malnutrition. However, high implementation fidelity is needed to achieve these effects in real-life practice. This study aimed to investigate the implementation fidelity of an evidence-based prehabilitation program in the real-life context of a Dutch regional hospital.

In clinical movement biomechanics, kinematic measurements are collected to characterise the motion of articulating joints and investigate how different factors influence movement patterns. Representative time-series signals are calculated to encapsulate (complex and multidimensional) kinematic datasets succinctly. Exacerbated by numerous difficulties to consistently define joint coordinate frames, the influence of local frame orientation and position on the characteristics of the resultant kinematic signals has been previously proven to be a major limitation.
