Abstract:

Background: Small bowel perforations are a rare diagnosis compared with esophageal, gastric, and colonic perforations. However, small bowel perforations can be fatal if left untreated. A classification of small bowel perforations or treatment recommendations do not exist to date. Methods: A retrospective, monocentric, code-related data analysis of patients with small bowel perforations was performed for the period of 2010 to 2019. Results: Over a 10-year period, 267 cases of small bowel perforation in 257 patients (50.2% male and 49.8% female; mean age of 60.28 years) were documented. Perforat

Abstract:

The article is aimed at studying the operation of welded I-beams with corrugated web and technological perforations under static loading. The relevance of the study is due to the lack of specific instructions on the pitch, diameter and methods of strengthening technological perforations in the Republic of Kazakhstan and other countries. In this study the method of computer modeling with the help of the program complex LIRA-SAPR-2022 was used. The study was carried out for the beam, taking into account different sizes of perforations in the beam web, distances between the perforations, with and

Abstract:

AbstractTympanic membrane perforation causes a sound conduction disturbance, and the size of this conduction disturbance is proportional to the perforation area. However, precise evaluation of perforation size is difficult, and there are few detailed reports addressing this issue. Furthermore, such evaluation becomes more difficult for irregularly shaped perforations. This study conducted a quantitative evaluation of tympanic membrane perforations, using image analysis equipment.A significant correlation was found between the degree of sound conduction disturbance and the perforation area; thi

After 50 days, all hydrocortisone-treated perforations were open, whereas the controls closed within 9 to 12 days. At 3 months, when one third of the perforations still were open, the TMs were studied by otomicroscopy and light microscopy. All TMs

Abstract:

Previous investigations into the healing and reconstruction of tympanic membrane (TM) perforations have involved animal models with acute TM perforations. A problem with the acute TM perforation model is that most acute TM perforations will heal spontaneously, both in animals and human beings. A second inadequacy of acute perforation models is that they are not analogous to the salient problem in human beings: Longstanding TM perforation. The ideal animal model must have a TM perforation that is permanent, well-eplthelialized, and free from infection. The perforation must also be subtotal to p

Objective: To present a clinical observation of a patient with pseudomembranous colitis (PMC) complicated with multiple colon perforations, and of post-surgery recovery. Key Points. Severe PMC can cause complications, such as toxic dilatation and perforation on colon, requiring emergency surgery. Clinical observation demonstrates the advisability of extended surgery for a patient with PMC complicated with perforations. Conclusion. PMC is a dangerous disease; a severe disease can cause colon perforation and require emergency surgery. Near-total colon excision in perforation in patients with PMC

Abstract:

The perforations play an important role in determining the near-wellbore fracture geometry during the stimulation phase. To address the impact of perforations on fracture geometry in horizontal wells, a 3D coupled hydromechanical finite element model is developed and employed. Based on the theory of continuum damage mechanics, scalar damage variable governs the degradation of the stiffness of the solid. Damage affects the crack element modeling that is used to consider crack behavior and construct a crack-tracking algorithm to simulate propagation. The model was validated against the analytica
