Vascular Trauma
Published in James Michael Forsyth, How to Be a Safe Consultant Vascular Surgeon from Day One, 2023
According to the respectable resources I use, the correct answer to get some X-rays first of all. Bullets do not respect anatomical boundaries, and we know this bullet has not left the body yet. As such, it may have traversed into another body cavity or region (e.g., into chest, abdomen or pelvis).
General Surgery

This is a laparoscopic port (Figure 7.19). It is a pen-shaped laparoscopic instrument with a sharp end which is encased by a sleeve/cannula. It is inserted through the skin to create a surgical opening into the body cavity. The trocar is then removed leaving the cannula/sleeve in situ providing surgical access to the site of operation laparoscopically whilst sealing the skin. It makes laparoscopic surgery possible by providing access to surgical equipment including laparoscopes, graspers and electrosurgical electrodes. It also allows the removal of body tissues including biopsy samples.
De Fabrica Humani Corporis—Fascia as the Fabric of the Body
Published in David Lesondak, Angeli Maun Akey, Fascia, Function, and Medical Applications, 2020
The interstitium is the third dimension of fascia and mesenchyme. It comprises a vast inner space that can be found everywhere between organs and tissue elements. It could be regarded as one continuous inter-anatomical body cavity along which chemical transport, communication, and organization are possible by means of various cellular substances.22,24 From embryology we know that signaling proteins are organized and distributed via the mesenchyme. During human embryonic development the meso provides the metabolic conditions for the development of the ectodermal structures and plays a role in their differentiation.21 Perhaps even epigenetic control molecules could be established via diffusion through the interstitial space.

The insect midgut is the target for economically important entomopathogens used in pest control (e.g., Bacillus thuringiensis and baculoviruses) and, as such, it has been intensively studied within the framework of the fine characterization of the mode of action of these microbes and their potent virulence factors (Lacey et al. 2015). On the other hand, the midgut is a barrier for many promising bioinsecticidal molecules, individuated so far and yet to be discovered, that have their target in the insect body cavity (i.e. the hemocoel) and that, after ingestion, may be unable to cross the gut epithelium and reach the hemocoel in an unaltered form and/or insufficient quantity to exert their activity (Bonning and Chougule 2014). For this reason, nanotechnology is a promising approach that would improve the efficiency of various bioinsecticides. The insect digestive system is one main physiochemical barrier against the pathogenic agents. In this way, the morphology and histopathological changes in the midgut structure can support to understand the insect defense mechanisms and the effectiveness of a biosynthesized insecticide.
Exteriorization of the distal catheter for ventriculoperitoneal shunt protruding through the peritoneal space: experience with 1 case

Extrusion of the lower end of VP shunts have been reported but is rare. Migration from one body cavity to another occurs in less than 0.1% of cases.3 The most prevalent type reported is the migration within the abdomen.4 Extrusion through the abdominal shunt incision is extremely rare. We were unable to identify the specific cause of extrusion in this case. Murat Vural et al.5 assumed that the catheter could irritate the peritoneum and provoke inflammation which could erode tissue, allowing migration over time. Maknojia A. et al.6 suggest that patients with a high body mass index (BMI) are prone elevated intraabdominal pressure and hence an increased propensity for catheters to migrate from the peritoneum. Abode-Iyamah KO. et al.7 found that a BMI >30 kg/m2 was an independent risk factors for distal catheter migration. In our case, the patient presented with abdominal obesity and we think the catheter migrated from the abdominal to the peri- incisional region related to this but why it progressed to extrusion is not clear.

Data presented in Figure 1, gonadectomy was performed after a month of being back to ad libitum feeding and 2 wk post-surgery recovery, animals were subjected to the CR regimen described below. Gonadectomy in female mice was performed as previously described [19,46,47]. Briefly, the anesthetized animal with isoflurane was placed in ventral recumbency, and the mid-dorsal region was carefully shaved. A small (approx. 0.5 cm) lateral incision was made through the skin of the back of the mouse in the mid-lumbar region. The skin was slid from side-to-side to locate the position of the ovaries beneath the peritoneal wall. While holding the abdominal wall up, a small incision was made in the abdominal wall over the ovarian fat pad and the ovary exteriorized. The ligaments were carefully torn to release the ovary. A clamp was placed across the tip of the uterine horn, and a ligature was placed just underneath the tip of the uterine horn. The ovary/oviduct was removed by cutting above the ligature. The uterine horn was repositioned into the body cavity. The abdominal wall was closed with one or two simple interrupted sutures. This procedure was repeated for removal of the second ovary. The skin incision was closed with vicryl rapide suture. Post-surgery the animal was administered with the analgesic flunixin 0.25mg/ml to reduce pain.
