Background A detection of parathyroid glands by the evaluation of their autofluorescence in the near-infrared spectrum is considered as a promising tool in addition to their visual verification. The aim of this study was to evaluate the role of near-infrared autofluorescence application by using two different image-based systems for the identification of parathyroid glands during surgery of thyroid and parathyroid benign and malignant lesions. Methods Evaluation of near-infrared autofluorescence was performed in 15 patients by using two different image-based systems equipped with a near-infrared laser camera. Intravenous injection of fluorophore indocyanine green was used for the enhancement of near-infrared autofluorescence signal. Results Normal parathyroid glands were identified and mobilized after visual inspection in 12 (80%) patients, which was confirmed by near-infrared autofluorescence evaluation. Confident recognition of parathyroid glands by near-infrared autofluorescence signal and their subsequent distinction from lymph nodes was achieved in two (13%) patients with prior surgery for papillary thyroid carcinoma. In one (7%) case, parathyroid gland was identified as fragments of tissue within the postoperative scarring area by near-infrared autofluorescence evaluation, but not by visual inspection. A less intensive near-infrared autofluorescence signal was detected in the parathyroid gland owing to unintentional excision in one (7%) case. Better signal intensity from parathyroid glands was noticed after changes of the near-infrared camera in Fluobeam 800 image-based system in position to an angle of approximately 45–65° in relation to area of interest in all cases as compared with holding straight on the parathyroid gland. Fluobeam LX demonstrated a good near-infrared autofluorescence signal without any specific changes in the camera angle. Thyroid carcinoma demonstrated low-intensity signal in the case of invasion to thyroid capsule. No fluorescent signal was identified from metastatic, or from normal, lymph nodes. Conclusions The application of near-infrared autofluorescence imaging is considered as a useful, but additional, tool for the visual assessment of parathyroid gland in the case of primary neck exploration. The utility of near-infrared autofluorescence imaging for parathyroid detection is increased in the case of repeated surgical intervention owing to increased risk of unintentional parathyroid removal as well as for discrimination of parathyroids from the lymph nodes in cases of thyroid malignancy.
Background A gunshot wound to the colon is a frequent injury in armed conflicts. An example of a high-energy modern weapon is hollow-point bullets, which is associated with increased tissue damage and lethal outcome. The aim of this study was to evaluate gunshot injuries to the colon in combat patients and to assess the difference in clinical features of patients with colon injuries by hollow-point versus shape-stable bullets. Patients and methods Analyses of clinical data were performed on 374 male soldiers from the Armed Forces of Ukraine with gunshot abdominal wounds with injury to the colon in East Ukraine between 2014 and 2020. Out of 374 injured, 112 (29.9%) patients were diagnosed with penetrating gunshot bullet wounds: 69/112 (61.6%) were injured by shape-stable bullets, and the hollow-point bullets injured 43/112 (38.4%) patients. Results More severe hemorrhagic shock stages were in patients injured by hollow-point bullets: shock stages III-IV was in 25 (58.1%) patients injured by the hollow-point bullets vs. 17 (24.6%) patients injured by shape-stable bullets (p = 0.0004). Left colon parts were more frequently injured as compared to the right colon side or transverse colon: 21 (48.8%) patients were injured by the hollow-point bullets (p < 0.0001), and 41 (59.4%) patients were injured by the shape-stable bullets (p = 0.032). A significant difference was identified for the frequent injury to the middle colon within the entire cohort (p = 0.023). Patients injured by the hollow-point bullets demonstrated a higher frequency of 3–5 areas of colon gunshot defects, which was detected in 18 (41.8%) patients injured by hollow-point bullets and none with shape-stable bullets injury (p = 0.0001). Colon Injury Scale (CIS) IV was detected in 7 (16.3%) patients injured by the hollow-point bullets as compared to 2 (2.9%) patients injured by shape-stable bullets (p = 0.011). Colostomy was performed in 14 (69%) patients injured by shape-stable bullets and in 12 (27.9%) patients injured by hollow-point bullets (p > 0.05). 15 (35%) patients died after injury by the hollow-point bullet, whereas 9 (13%) patients after damage by the shape-stable bullets (p = 0.0089). Conclusions All patients should be suspected to have an injury by bullet with expanding properties in case of penetrating abdominal injury (absent of outlet wound) and careful revision of the abdomen must be performed to identify possible multiorgan injury as well as multiple gunshot defects of the intestine.
Background The current war in Ukraine is associated with frequent applications of multiple-launch rocket systems and cruise missiles as well as other various high-energy weapons to cause severe injuries in military personnel including abdomen wounds, vascular injury, and limb amputations as well as genitourinary trauma. The aim of this report is to demonstrate a case of successful penile salvage by restoring its function in a combat patient with gunshot genitourinary trauma in conditions of an interrupted supply of medical equipment. Case presentation We describe a case of a 48-year-old male patient with a combined shrapnel gunshot wound to the penis with damage to the urethra and combined injury to the soft tissues of the left thigh. Several hours after the injury, the patient underwent primary surgical debridement of the left thigh, ligation of the great saphenous vein of the thigh, primary sutures on the penile urethra and navicular fossa, suturing of the rupture of the head and penis, drainage of the wound, catheterization of the bladder, and epicystostomy. An artificial erection was performed intraoperatively. The urethral catheter was removed 3 weeks after urethral suturing (May 4, 2022). The epicystostomy was removed 5 months after the injury (August 4, 2022) and 2 days after the restoration of spontaneous urination. At the follow-up of 7 months after the injury, the patient has normal urination with minor urinary dribbling, sufficient erection, and ejaculation. Conclusions We have shown that in a case of gunshot wounds to the penis and hanging part of the urethra, even in the presence of combined severe purulent lesions of non-urological localizations, it is possible to perform a primary reconstruction of urogenital injuries using a primary urethral suture and applying a negative pressure device. Findings from this case report shed new light on the management of penile gunshot injury in ongoing warfare as well as provide evidence of the possibility to perform adequate management for penile injury in conditions of limited medical resources, violation of international humanitarian law, and under frequent strikes of high-energy weapons.
