Abstract
OBJECTIVES Some of the most common problems after kidney transplant are urologic complications, including ureterocystoanastomosis leakage and stenosis with the development of severe renal graft complications. Isolated plasma contains active substances that cause the activation of various growth factors for the processes of tissue repair or regeneration, has an anti- inflammatory effect, activates angiogenesis, and reduces the risk of infectious complications. Platelet-rich plasma is actively used to stimulate bone regeneration, heal wounds and ulcers on the skin, enhance reconstruction of the larynx and trachea, and ameliorate urethral damage, among other uses. This study was developed to evaluate the positive effect of platelet-rich plasma on the healing process of an anastomotic wound in a model of ureterocystoanas-tomosis in rats. MATERIAL AND METHODS We randomized 14 Wistar albino male rats into 2 groups: group 1 included 7 rats that received platelet-rich plasma after ureterocystostomy; group 2 was the control group and included 7 rats that underwent ureterocystostomy without platelet-rich plasma. On postoperative day 7, all animals were euthanized, and the anastomosis area was resected for determination of the tissue hydroxyproline levels and histopathology examination. RESULTS Tissue hydroxyproline levels were 767 ± 62.9 μg/g in group 1 and 256 ± 28.0 μg/g in group 2. Tissue hydroxyproline levels were significantly higher in group 1 compared with group 2 (P < .05). There were no significant differences in epithelial damage, acute inflammation, or fibrosis between the tissue samples of both groups. CONCLUSIONS The results of this study show that the use of platelet-rich plasma during ureterocystostomy produces a positive effect. Our further research will be devoted to the use of autologous platelet-rich plasma in ureterocystostomy in big models.

Platelet rich plasma effectiveness in bowel anastomoses: A systematic review. World J Gastrointest Surg 2021; 13:1736-1753. [PMID: 35070077 PMCID: PMC8727194 DOI: 10.4240/wjgs.v13.i12.1736] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2021] [Revised: 08/11/2021] [Accepted: 11/18/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Anastomotic leak constitutes a major problem in abdominal surgery. Technical insufficiency, topical or systemic factors contribute to disrupted healing of the performed bowel anastomosis and result in anastomosis leakage, with detrimental effects on patient postoperative outcomes. Despite the investigation of several factors and the invention of protective materials, the ideal agent to prevent anastomotic leaks is yet to be determined.
AIM To study the effect of platelet rich plasma (PRP) on the healing of bowel anastomoses.
METHODS A systematic literature search was performed in PubMed, EMBASE, and Scopus databases to identify studies investigating the effect of PRP application on bowel anastomosis.
RESULTS Eighteen studies were eligible with a total population of 712 animals including rats (14 studies), rabbits (2 studies) and pigs (2 studies). No postoperative complications were reported following PRP application. Fourteen out of 18 studies reported a statistically significant higher anastomosis bursting pressure in PRP groups compared to control either in healthy animals or animal models with underlying condition or intervention, such as intraperitoneal chemotherapy or peritonitis. Similar results were reported by ten studies in terms of tissue hydroxyproline levels. One study reported significant increase in collagen deposition in PRP groups. PRP application resulted in significantly decreased inflammatory cell infiltration in the presence of peritonitis or intraperitoneal chemotherapy (6 studies).
CONCLUSION The application of PRP is associated with improved bowel anastomosis outcomes, especially in animal models having an underlying condition affecting the normal healing process. PRP application seems to augment the normal healing process under these circumstances. However, further studies are needed to investigate the potential role of PRP on bowel anastomosis healing, especially in clinical settings.

Acta Cir Bras 2020; 35:e202000504. [PMID: 32638844 PMCID: PMC7341987 DOI: 10.1590/s0102-865020200050000004] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2020] [Accepted: 04/22/2020] [Indexed: 12/18/2022] Open
Abstract
Purpose 5-flourourasil (5-FU) is commonly used for early intraperitoneal chemotherapy in colorectal or appendiceal cancer patients with peritoneal carcinomatosis. Due to its effect, anastomosis healing can be impaired and leads to anastomotic leakage. In this study, we aimed to investigate the potential healing effect of platelet-rich plasma (PRP) on colonic anastomosis impaired by intraperitoneal 5-flourouracil application. Methods After ten rats were sacrificed for preparing PRP, forty Wistar-albino rats were subjected to colonic anastomosis, and randomly allocated into four groups including 10 rats each. According to receiving PRP and/or 5-FU application, the groups were formed as control (C), 5-FU without PRP (CT), anastomosis with PRP (C-PRP), and 5-FU with PRP (CT-PRP). CT and CT-PRP groups also received 5-FU intraperitoneally on postoperative day 1 (POD 1). All animals were euthanized on pod 7. The body weight change, anastomotic bursting pressure (ABP), tissue hydroxiprolin (TH) and histopathological examination of each group were analyzed. Results 5-FU application significantly reduced ABP levels when compared with group C, C-PRP and CT-PRP (for each comparison, p<0,01). PRP application in CT-PRP group raised the measure of ABP up to the levels of C group. Although tissue hydroxyproline levels (THL) levels of CT-PRP group were found higher than CT group, it was not significant (p=0.112). Microscopically, comparing with CT group, PRP application significantly promoted the healing of colonic anastomosis subjected to 5-FU application by improving tissue edema, necrosis, submucosal bridging and collagen formation (p<0.05). Tissue healing in CT-PRP group was observed as good as the control groups. (C, C-PRP, p=0.181, p=0.134; respectively). Conclusion PRP administration on colonic anastomosis significantly promotes the healing process of anastomosis in rats receiving 5-FU. This result encourages further clinical use of PRP to reduce the frequency of AL in patients receiving EPIC.

Comparison of Platelet-Rich Plasma-Impregnated Suture Material with Low and High Platelet Concentration to Improve Colonic Anastomotic Wound Healing in Rats. Gastroenterol Res Pract 2020; 2020:7386285. [PMID: 32565785 PMCID: PMC7271001 DOI: 10.1155/2020/7386285] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2019] [Revised: 03/14/2020] [Accepted: 04/07/2020] [Indexed: 01/27/2023] Open
Abstract
Objective This study was designed to investigate the impact of using suture material impregnated with platelet-rich plasma (PRP) in different platelet concentrations on colonic anastomotic wound healing in rats. Methods A total of 24 Sprague Dawley female rats were separated into 3 groups (n = 8 for each) including the control group (CON; standard vicryl suture repair), the low platelet concentrate PRP group (L-PRP; suture material impregnated with PRP containing average 2.7-fold (range, 2.0 to 3.1) higher amount of platelets vs. control), and the high platelet concentrate PRP group (H-PRP; suture material impregnated with PRP containing average 5.1-fold (range, 4.8 to 5.4) higher amount of platelets vs. control). Rats were sacrificed on the postoperative 7th day for analysis of colonic anastomosis region including macroscopic observation, measurement of anastomotic bursting pressure (ABP), and the hydroxyproline levels and histopathological findings in colon tissue samples. Results Total injury scores were significantly lower in the L-PRP and H-PRP groups than those in the control group (median (range) 13.00 (7.00) and 11.50 (6.00) vs. 15.50 (4.00), p < 0.05 and p < 0.01, respectively). ABP values (180.00 (49.00) vs. 124.00 (62.00) and 121.00 (57.00) mmHg, p < 0.001 for each) and tissue hydroxyproline levels (0.56 (0.37) vs. 0.25 (0.17) and 0.39 (0.10) μg/mg tissue, p < 0.001 and p < 0.05, respectively) were significantly higher in the L-PRP group as compared with those in the control and H-PRP groups. Conclusion In conclusion, our findings revealed PRP application to colonic anastomosis sutures to promote the anastomotic healing process. The platelet concentration of PRP seems to have a significant impact on the outcome with superior efficacy of L-PRP over H-PRP in terms of bursting pressures and collagen concentration at the anastomotic site.

ANZ J Surg 2020; 90:2290-2297. [PMID: 32436284 DOI: 10.1111/ans.15993] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2020] [Revised: 04/25/2020] [Accepted: 04/29/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Hyperthermic intra-peritoneal chemotherapy (HIPEC) performed in patients with peritoneal carcinomatosis has a cytotoxic effect on tumour cells. This cytotoxic effect also adversely affects the wound healing of anastomosis, which is frequently undertaken in this patient group, and causes anastomotic leakage and intestinal fistulas. Platelet-rich plasma (PRP) gel has been used in wound healing and has shown efficacy. We investigated the effect of PRP gel on colon anastomosis healing in rats treated with 5-fluorouracil (5-FU). METHODS Twenty-four rats were divided into three groups, each containing eight rats: group 1 (control) underwent colon anastomosis alone; group 2 (5-FU) underwent a colon anastomosis and HIPEC; and group 3 (5-FU + PRP) underwent a colon anastomosis and HIPEC and received topical PRP gel. The rats were sacrificed on the post-operative day 7 and the anastomotic bursting pressure (ABP) was measured. Tissue samples were obtained to measure the hydroxyproline level and investigate the histopathological changes on the anastomosis line. RESULTS ABP was higher in the control and 5-FU + PRP groups than in the 5-FU group (P = 0.009, P = 0.047). The tissue hydroxyproline levels were higher in the control and 5-FU + PRP groups than in the 5-FU group (P = 0.001, P = 0.030). The histopathological findings of the 5-FU + PRP group were better than those of the 5-FU group. CONCLUSION This study showed that the application of PRP gel to colon anastomoses increased ABP in rats treated with HIPEC using 5-FU. It also showed positive effects on anastomotic healing by increasing the tissue hydroxyproline levels on the anastomosis line and reducing the inflammatory response.

Abstract
Purpose Hyperthermic intraperitoneal chemotherapy (HIPEC) is a novel treatment option for peritoneal surface malignancies. Due to cytotoxic effects of chemotherapeutic agents, anastomosis healing can be impaired and lead to leakage rates higher than conventional intestinal surgery. In this experimental study, we aimed to investigate the effects of platelet-rich plasma (PRP) on colonic anastomosis in rats that received HIPEC with oxaliplatin. Methods Thirty rats were divided into 3 groups. Group 1 was determined as control group and hyperthermic saline perfusion was performed after colon anastomosis. In group 2, colon anastomosis then hyperthermic oxaliplatin perfusion was performed. In the last group, the colonic anastomosis was enhanced by PRP gel and then hyperthermic oxaliplatin perfusion was performed. All the rats were reoperated on postoperative day 7 and anastomotic bursting pressure values were recorded. Tissue samples were taken for hydroxyproline assay and histopathological examination. Results Control group had higher anastomotic bursting pressure value than group 2 and group 3 (P < 0.001). There were significant differences in anastomotic bursting pressure between groups 2 and 3 (P < 0.001). Group 2 had significantly lower hydroxyproline levels than group 3 and control group (P < 0.001). Histopathological examination revealed that PRP application reduced inflammatory response. Conclusion PRP application on colonic anastomosis improves anastomotic healing and can reduce anastomosis related complications and stoma creation; though further clinical studies are needed.

Abstract
Bowel perforation is a rare, but serious complication of laparoscopic surgery with a mortality rate that reaches 20%. There are several risk factors that could predispose to bowel perforation, but the surgeon's experience and the difficulty of each case play the most important role. Delayed bowel injuries happen due to conduction of electrical energy through the abdominal cavity, and in the majority of cases require reoperation. Early bowel injuries are caused by thermal injury of an electrosurgical instrument or during the insertion of the laparoscopic instruments inside the peritoneal cavity. Such injuries are recognized during the operation and are usually fixed by placing sutures. TISSEEL™ is a fibrin sealant with various applications in several surgical specialties, that simulates the latter stages of the coagulation cascade, and could be used as an alternative treatment for confined bowel perforations during laparoscopy. The efficacy of fibrin sealants in closing bowel gaps has been tested in some experimental models as well as its adequacy in enhancing bowel anastomoses performed with sutures. In addition, there is scarce evidence that fibrin sealants enhance the healing process after bowel enclosure either combined to suturing or not, which is supported by an experimental pilot study, that was conducted by our study group. The present study tries to combine all the available data in order to propose an effective alternative treatment for confined bowel injuries or controversial cases, that happen during laparoscopic surgery. In that way, every surgeon could face them even without huge expertise, conversions to open surgery would diminish and the disadvantages of suturing would disappear. Future experimental studies should be designed in the terms of extensive comparison of the two methods, with the purpose of this comparison to be tested in humans in the future.

Abstract
Objectives: Ankaferd BloodStopper (ABS) is a topical hemostatic agent that modulates the inflammatory response and accelerates wound healing. The aim of this study was to determine the effects of ABS on the colon anastomosis wound healing in a rat model. Methods: Thirty-two Wistar albino rats were divided into four groups as follows: Group A (n=8), left colonic anastomosis plus ABS treatment (sacrificed on the 3rd day); Group B (n=8) (control), left colonic anastomosis (sacrificed on the 3rd day); Group C (n=8), left colonic anastomosis plus ABS treatment (sacrificed on the 7th day); and Group D (n=8) (control), left colonic anastomosis (sacrificed on the 7th day). All rats were sacrificed at the end of the experiment to assess the anastomosis integrity and the presence of perianastomosis abscesses, peritonitis, and adhesions. Additionally, the bursting pressure and hydroxyproline (OH-pyroline) levels were determined, and a histopathologic evaluation of the perianastomosis tissue was conducted. Results: The mean bursting pressure on Day 7 was significantly higher than that on Day 3 in the ABS group (p=0.017). Overall, the bursting pressure was higher in animals treated with ABS than in the control animals, although the difference was not statistically significant. The OH-pyroline levels of both ABS groups were significantly higher than in the control groups. The mean OH-pyroline level on Day 7 was higher than that on Day 3 in the ABS-treated animals (p=0.038). Conclusion: ABS increases collagen formation and neovascularization, and it has a positive impact during the colon anastomosis healing in an experimental model of wound healing.

Abstract
The aim of the current study was to evaluate the severity and location of flame burns and the mortality rate of civilians affected by these in the Syrian Civil War and to present the surgical treatment outcomes of the injured civilians to be able to provide recommendations. This was a prospective hospital-based observational cohort study involving 573 patients with data collected from 2011 to 2018. All of these patients were Syrian civilians, and their flame burn injuries were related to the Syrian conflict. All burns were divided into four subgroups according to TBSA and compared. The groups of TBSA were compared as 0 to 25% (n = 97), 25 to 50% (n = 257), 50 to 75% (n = 135), and >75% (n = 84) (P = .413). Almost all had a second (n = 331; 57.7%) and third (n = 189; 32.9%) degree deep burns. The median burn size was 47% TBSA in the patients. The burn mechanism was mostly the flame type of burn (n = 467; 81.5%) as a result of fuel oil explosions, followed by bomb-related burns (n = 106; 18.5%) (P < .001). Mortality was seen in 223 (39%) due to the high surface area and reaching hospital too late at 1 to 8 days (P = .187). The findings of this study indicate that war-related flame burns result in an extremely high mortality rate and time is lost, which could protect against life-threatening outcomes.

Abstract
Background and objectives: Rat experimentation is the first line of research by which a medical hypothesis is usually tested. Platelet Rich Fibrin (PRF) is a relatively new bio-material that has shown promise to enhance healing in the field of bone research and tissue engineering. In order to perform PRF based experiments on rats, a proper protocol of obtaining PRF from rats needs to be established. Materials and Methods: 35 Wistar rats were used to obtain PRF by using cardiac puncture blood draw and quick subsequent centrifugation. The PRF samples wereanalyzed and compared to standard literature PRF composition. Results: PRF samples analysis showed persistent results pertaining to known PRF composition. Conclusions: Our experiment has shown that our protocol of obtaining PRF is capable of providing high quality PRF from rats.
