Abstract
AIM This study investigated the regenerative efficacy of leukocyte platelet-rich fibrin (L-PRF) on colon anastomotic healing in rabbits. MAIN METHODS Thirty-six healthy male white New Zealand rabbits were subjected to complete transactions of the ascending colon. The rabbits were equally divided into two groups: the control group, where the transected colon ends were anastomosed by a simple interrupted suture pattern, and the L-PRF-treated group, in which L-PRF was wrapped entirely around the anastomotic line. The postoperative acute pain scale was assessed using the Bristol Rabbit Pain Scale before surgery and at each four-hour interval post-operatively. After euthanizing the rabbits, the adhesion degree score, anastomotic bursting pressure, and stenosis degree of the anastomotic colon were assessed, and histopathological examination at the 7th, 14th, and 28th days postoperatively. KEY FINDINGS Rabbits in both groups showed a significant increase in pain scores compared to baseline. Postoperatively, the L-PRF group exhibited significantly lower pain scores, adhesion scores, and stenosis degrees than the control group. However, the anastomotic bursting pressure was significantly higher in the L-PRF group. Re-epithelialization, polymorphonuclear neutrophil infiltration, granulation tissue formation, and collagen deposition scores were improved considerably in the L-PRF group compared to the control group. Immunostaining of growth factor expression was significantly lower in the control than in the L-PRF group. SIGNIFICANCE The L-PRF can augment collagen deposition, re-epithelialize the mucosa, promote angiogenesis, reduce adhesions, and diminish the stenosis degree scores. Therefore, it can be considered a promising aid in healing bowel anastomoses.

Abstract
BACKGROUND Leakage following colorectal anastomosis surgery causes various complications associated with high morbidity and mortality, especially in pediatric patients. It might be caused by the use of non-steroidal anti-inflammatory drugs (NSAIDs) as postoperative analgesics. This study aimed to compare the effect of metamizole and paracetamol on colonic anastomosis and fibroblast activities, including proliferation, migration, and collagen synthesis, in Wistar rats. METHODS Rats were divided into control, paracetamol and metamizole groups. The colonic anastomosis was evaluated by determining the integrity of the muscle layers, the formation of granulation tissue, and mucosal anastomosis. Fibroblast activities were analyzed by measuring the proliferation, migration, and collagen synthesis. RESULTS Metamizole caused more damage to muscle layer integrity, more inhibition of granulation tissue formation in the anastomosis area and lower mucosal anastomosis compared with paracetamol and control groups. Metamizole had a higher cytotoxic effect than paracetamol, which suppressed the proliferation and migration of fibroblasts. Furthermore, both drugs did not affect the synthesis of collagen. CONCLUSION Metamizole shows worse effects on the integrity of muscle layers, inhibition of granulation tissue formation, mucosal anastomosis, fibroblast proliferation, and migration, but not collagen synthesis, than paracetamol in Wistar rat intestines following colonic anastomosis. These findings might indicate that paracetamol is safer than metamizole as analgesic following colonic anastomosis.

Abstract
Background. Postoperative adhesions are the result of aberrant peritoneal healing. As they are the leading cause of postoperative bowel obstruction, anti-adherence barriers are advocated for their prevention. This study looks into the effect of these biomaterials on the healing of intestinal anastomoses. Materials and Methods. Thirty-three New Zealand White rabbits underwent laparotomy, transection of the terminal ileum, and creation of an end-to-end anastomosis. Animals were randomized into 3 groups: the Control group (n = 11); the Icodextrin group, receiving icodextrin 4% intraperitonealy (n = 11); and the HA/CMC group, having the anastomosis wrapped with a hyaluronic acid/carboxymethylcellulose film (n = 11). All animals were sacrificed on the seventh postoperative day. Macroscopic adhesions were graded and anastomotic strength was tested by the burst pressure. Histological healing was assessed in a semiquantitative way for the presence of ulceration, reepithelization, granulation tissue, inflammation, eosinophilic infiltration, serosal inflammation, and microscopic adhesions. Univariate and multivariate analysis was used. Results are given as medians with interquartile range. Results. The median adhesion scores were the following: Control 1 (0-3), Icodextrin 0 (0-1), HA/CMC 0 (0-0), P = .017. The burst pressure did not differ between the groups; however, all except one bowel segments tested burst away from the anastomosis. The macroscopic and histological anastomotic healing was comparable in all 3 groups. A poor histological anastomotic healing score was associated with a higher adhesion grade (odds ratio = 1.92; 95% confidence interval = 1.06-3.47; P = .032). Conclusion. Adhesion formation was inhibited by the materials tested without direct detrimental effects on anastomotic healing. Poor anastomotic healing provokes adhesions even in the presence of anti-adhesion barriers.

Abstract
In this experimental study, we investigated the effects of a 5-day postoperative treatment with the nonsteroidal anti-inflammatory drug (NSAID) diclofenac on anastomotic healing in rabbits. NSAIDs are widely used analgesics in today's “fast-track surgery,” raising concerns about their potential negative effects on healing in humans. A total of 33 New Zealand White female rabbits underwent laparotomy and 2 separate end-to-end anastomoses of the ileum.. The animals were randomized to receive subcutaneous diclofenac 4 mg/kg/d (17 experimental rabbits) or subcutaneous isotonic saline 0.1 mL/kg/d (16 control rabbits) postoperatively. On the fifth postoperative day, the animals were humanely killed, and anastomotic leakage, anastomotic breaking strength, and histopathologic changes were evaluated. Breaking strength in the diclofenac group was 21% lower than in the placebo group (P = 0.027). Anastomotic leakage was found in 4 rabbits in the diclofenac group (26.7%). The rabbits treated with diclofenac demonstrated a 16% lower collagen deposition compared with the placebo group (P = 0.008). In our study, postoperative treatment with diclofenac had a negative effect on the anastomotic healing and strength in the ileum of rabbits. Caution should be taken in the use of diclofenac after gastrointestinal surgery.

Abstract
BACKGROUND Enhanced recovery programs following colorectal resection recommend the use of nonsteroidal anti-inflammatory drugs (NSAIDs) as part of multimodal analgesia. The present study aimed to assess whether postoperative NSAID use increased the risk of anastomotic leak. METHODS A systematic review of published literature was performed for studies comparing anastomotic leak following NSAID administration versus control. Meta-analysis was conducted for studies in human patients and experimental animal models. The primary endpoint was anastomotic leak. RESULTS The final analysis included 8 studies in humans and 12 experimental animal studies. Use of NSAIDs was significantly associated with anastomotic leak in humans (8 studies, 4,464 patients, odds ratio [OR] 2.14; p < 0.001). This effect was seen with nonselective NSAIDs (6 studies, 3,074 patients, OR 2.37; p < 0.001), but not with selective NSAIDs (4 studies, 1,223 patients, OR 2.32; p = 0.170). There was strong evidence of selection bias from all clinical studies, with additional inconsistent definitions and outcomes assessment. From experimental animal models, anastomotic leak was more likely with NSAID use (ten studies, 575 animals, OR 9.51; p < 0.001). Bursting pressures at day 7 were significantly lower in NSAID versus controls (7 studies, 168 animals, weighted mean difference -35.7 mmHg; p < 0.001). CONCLUSIONS Emerging data strongly suggest that postoperative NSAIDs are linked to anastomotic leak, although most studies are flawed and may be describing pre-existing selection bias. However, when combined with experimental data, these increasing concerns suggest caution is needed when prescribing NSAIDs to patients with pre-existing risk factors for leak, until more definitive evidence emerges.

Abstract
BACKGROUND Recent evidence has suggested an association between postoperative non-steroidal anti-inflammatory drugs (NSAIDs) and increased operation-specific complications. This study aimed to determine the safety profile following gastrointestinal surgery across a multicentre setting in the UK. METHODS This multicentre study was carried out during a 2-week interval in September-October 2013. Consecutive adults undergoing elective or emergency gastrointestinal resection were included. The study was powered to detect a 10 per cent increase in major complications (grade III-V according to the Dindo-Clavien classification). The effect of administration of NSAIDs on the day of surgery or the following 2 days was risk-adjusted using propensity score matching and multivariable logistic regression to produce adjusted odds ratios (ORs). The type of NSAID and the dose were registered. RESULTS Across 109 centres, early postoperative NSAIDs were administered to 242 (16·1 per cent) of 1503 patients. Complications occurred in 981 patients (65·3 per cent), which were major in 257 (17·1 per cent) and minor (Dindo-Clavien grade I-II) in 724 (48·2 per cent). Propensity score matching created well balanced groups. Treatment with NSAIDs was associated with a reduction in overall complications (OR 0·72, 95 per cent confidence interval 0·52 to 0·99; P = 0·041). This effect predominantly comprised a reduction in minor complications with high-dose NSAIDs (OR 0·57, 0·39 to 0·89; P = 0·009). CONCLUSION Early use of NSAIDs is associated with a reduction in postoperative adverse events following major gastrointestinal surgery.

Abstract
INTRODUCTION Non-steroidal anti-inflammatory drugs (NSAIDs) decrease postoperative pain and opioid consumption. The objective of the study was to determine if postoperative NSAIDs were associated with anastomotic leaks following elective colorectal surgery. MATERIALS AND METHODS We used a matched nested case-control study design. Using a prospectively collected database, we identified all patients having elective colorectal surgery between January 2001 and June 2012. Cases and matched controls were identified based on the occurrence of a postoperative anastomotic leak. The primary and secondary exposure variables were, respectively, use of any NSAID and use of ketorolac specifically. Conditional logistic regression was used to determine the unadjusted and adjusted odds ratio. RESULTS A total of 262 patients were included (65.6 % inflammatory bowel disease, 34.4 % cancer). Use of any NSAID was associated with a non-significant increase in anastomotic leaks (odds ratio (OR) 1.81, 95 % confidence interval (CI) 0.98-3.37, p = 0.06). Use of ketorolac was associated with a significant increase in anastomotic leaks (OR 2.09, 95 % CI 1.12-3.89, p = 0.021). There was no significant association between anastomotic leaks and cumulative NSAID dose. CONCLUSION These data suggest that there may be an association between NSAIDs and risk of anastomotic leaks after colorectal surgery. Further research is needed to better elucidate this relationship to clarify the implications for patients.

Abstract
BACKGROUND The aim of this experimental study was to investigate whether the perioperative administration of the selective cyclooxygenase-2 inhibitor celecoxib affects the angiogenetic process and the healing of colonic anastomoses. METHODS Seventy-two male Wistar rats underwent colonic resection and anastomosis. Celecoxib (10 mg/kg/day-celecoxib group) or placebo (control group) was administered perioperatively. Rats of both groups were sacrificed on either the third or the seventh postoperative day and bursting pressures of the anastomoses were measured. Gelatine-degrading matrix metalloproteinases (MMPs) were identified with gelatine zymography, and proMMP-2 and vascular endothelial growth factor (VEGF) levels from both anastomotic site and tissue adjacent to the anastomosis were evaluated. Histologic evaluation of microvessels was performed by immunohistochemistry using an anti-CD34 monoclonal antibody. RESULTS Celecoxib did not significantly decrease anastomotic bursting pressures. Gelatin zymography revealed the presence of MMP-2, proMMP-2, and proMMP-9. MMP concentration was higher at the anastomotic tissue as compared with tissue distant to the anastomosis. Celecoxib resulted in a significant reduction in proMMP-2 levels at the anastomosis at both third and seventh postoperative day. VEGF levels from the anastomotic tissue were also found lower in the celecoxib group. Histological examination showed a celecoxib-induced reduction of newly formed CD34-stained vessels. CONCLUSIONS Although the perioperative administration of celecoxib resulted in suppression of angiogenesis in the newly formed anastomoses, bursting pressures remained unaffected and subsequently safety was not compromised.

Abstract
BACKGROUND Non-steroid anti-inflammatory drugs such as the cyclooxygenase isoenzyme inhibitors diclofenac and naproxen are increasingly used for perioperative pain relief, while their potential effects on wound healing are scarcely investigated. METHODS In 104 male Wistar rats, an anastomosis was constructed in both colon and ileum. The rats were divided into groups who received diclofenac (4 mg kg(-1) day(-1)) or naproxen (10 mg kg(-1) day(-1)) daily from the day of surgery or from day 3 after surgery. Animals were killed on day 3 or 7 and analysed for signs of anastomotic dehiscence and wound strength of anastomoses and abdominal fascia. RESULTS Anastomotic leakage in the ileum (p < 0.0001) and mortality rates (p = 0.001) were significantly increased in the diclofenac group. On day 7, the anastomotic bursting pressure in the ileum remained below that of the controls in the diclofenac- and naproxen-treated rats. When administration of diclofenac was postponed to day 3 after surgery, anastomotic dehiscence was almost absent. The colonic anastomosis and abdominal wall always remained unaffected. CONCLUSIONS This study implies that immediate postoperative administration of diclofenac and, to a far lesser extent, naproxen can affect healing in the ileal anastomosis in the rat. This negative effect can be prevented by a short postoperative delay in administration. On steroid anti-inflammatory drugs such as the cyclooxygenase isoenzyme inhibitors diclofenac and naproxen are increasingly used for perioperative pain relief, while their potential effects on wound healing are scarcely investigated.

Abstract
BACKGROUND Cyclo-oxygenase 2 inhibitors can be used for pain treatment after colorectal surgery. OBJECTIVE The aim of this study was to investigate whether the use of etoricoxib has negative effects on the perioperative outcome in colorectal surgery. DESIGN Complication data from an advanced medical database system were sampled prospectively, and patient records were reviewed retrospectively. PATIENTS All patients with elective colorectal surgery within an enhanced recovery after surgery protocol from 2008 to 2009 were selected. INTERVENTION The nonrandomized use of perioperative etoricoxib treatment was compared with a control group. MAIN OUTCOME MEASURES The primary outcome measured was the number of patients with postoperative complications according to the Dindo-Clavien classification. RESULTS One hundred one patients received etoricoxib treatment, whereas 104 did not. The patient groups were very comparable. We observed a significant increase in the number of patients with postoperative complications with etoricoxib treatment (43 vs 30 patients; 42.6% vs 28.8%, p = 0.041) due to an increase in patients with a major complication (Dindo-Clavien complication grade III-V: 22.8% vs 9.6%, p = 0.01). Patients with etoricoxib treatment and a complication needed a longer recovery period than patients with a complication in the control group (18 (17; 20) vs 14 (13; 15) days, p = 0.05). We observed an increased level of postoperative serum creatinine with etoricoxib treatment (105 (98; 112) vs 82 (78; 85), p = 0.003), which was more pronounced in patients with a complication (141 (127; 155) vs 91 (83; 98), p = 0.002; 25 vs 8 patients with serum creatinine >100 μmol/L, p = 0.008). In multivariate analysis, etoricoxib was identified as an independent risk factor for experiencing a major complication with a risk increase of approximately 2.5-fold (p = 0.03). LIMITATIONS This study was limited by the nonrandomized use of perioperative etoricoxib and the retrospective nature of its review of patient records. CONCLUSIONS Etoricoxib increased the number of patients with postoperative complications and should be considered carefully in colorectal surgery.

Abstract
BACKGROUND Nonsteroidal anti-inflammatory drugs are a key component of contemporary perioperative analgesia. Recent experimental and observational clinical data suggest an associated increased incidence of anastomotic dehiscence in bowel surgery. OBJECTIVE The aim of this study was to conduct a systematic review and meta-analysis of anastomotic dehiscence in randomized, controlled trials of perioperative nonsteroidal anti-inflammatory drugs. DATA SOURCES Published and unpublished trials in any language reported 1990 or later were identified by searching electronic databases, bibliographies, and relevant conference proceedings. STUDY SELECTION Trials of adults undergoing bowel surgery randomly assigned to perioperative nonsteroidal anti-inflammatory drugs or control were included. The number of patients with a bowel anastomosis and the incidence of anastomotic dehiscence had to be reported or be available from authors for the study to be included. INTERVENTION At least 1 dose of a nonsteroidal anti-inflammatory drug was given perioperatively within 48 hours of surgery. MAIN OUTCOME MEASURES The primary outcome measured was 30-day incidence of anastomotic dehiscence as defined by authors. RESULTS Six trials comprising 480 patients having a bowel anastomosis met inclusion criteria. In 4 studies, anastomotic dehiscence rates were higher in the intervention groups. Overall rates were 14/272 participants (5.1%) in intervention arms vs 5/208 (2.4%) in control arms. Peto OR was 2.16 (95% CI 0.85, 5.53; p = 0.11), and there was no heterogeneity between studies (I statistic 0%). LIMITATIONS Sizes of available trials were small, preventing firm conclusions and subset analysis of drugs of different cyclooxygenase specificity. A precise and consistent definition of anastomotic dehiscence was not used across trials. CONCLUSIONS A statistically significant difference in incidence of anastomotic dehiscence was not demonstrated. However, the Peto OR of 2.16 (0.85, 5.53) and lack of heterogeneity between trials suggest that this finding may be due to a lack of power of the available data rather than a lack of effect.

Abstract
PURPOSE The objective of this study was to investigate the effect of resveratrol on the healing process after midline laparotomy in rats. METHODS The study was performed on adult female Wistar-Albino rats. The study group was orally administered 0.5 mg/kg resveratrol once a day for 7 days before the operation until 12 h before surgery and then the treatment was maintained throughout the study. Each rat was anesthetized, and a 4-cm midline laparotomy was performed. Ten animals in each group were sacrificed on postoperative days 7, and 14. A tensile strength analysis was performed, hydroxyproline levels were measured, and the abdominal incision wounds were examined histologically. RESULTS Resveratrol administration significantly increased the tensile strength of the abdominal fascia, and increased the hydroxyproline levels on postoperative day 14. The acute inflammation scores, collagen deposition scores and the neovascularization scores on postoperative days 7 and 14 were found to be significantly higher in the resveratrol treatment group compared to the control group. The amount of granulation tissue and the fibroblast maturation scores were found to be significantly higher only on postoperative day 14 in the treatment group compared to the control group. CONCLUSION Our findings show that resveratrol may have a beneficial effect on incisional wound healing.

Abstract
Abstract
Background
Historically, the preoperative and postoperative care of patients with gastrointestinal cancer was provided by surgeons. Contemporary perioperative care is a truly multidisciplinary endeavour with implications for cancer-specific outcomes.
Methods
A literature review was performed querying PubMed and the Cochrane Library for articles published between 1966 to 2012 on specific perioperative interventions with the potential to improve the outcomes of surgical oncology patients. Keywords used were: fast-track, enhanced recovery, accelerated rehabilitation, multimodal and perioperative care. Specific interventions included normothermia, hyperoxygenation, surgical-site infection, skin preparation, transfusion, non-steroidal anti-inflammatory drugs, thromboembolism and antibiotic prophylaxis, laparoscopy, radiotherapy, perioperative steroids and monoclonal antibodies. Included articles had to be randomized controlled trials, prospective or nationwide series, or systematic reviews/meta-analyses, published in English, French or German.
Results
Important elements of modern perioperative care that improve recovery of patients and outcomes in surgical oncology include accelerated recovery pathways, thromboembolism and antibiotic prophylaxis, hyperoxygenation, maintenance of normothermia, avoidance of blood transfusion and cautious use of non-steroidal anti-inflammatory drugs, promotion of laparoscopic surgery, chlorhexidine–alcohol skin preparation and multidisciplinary meetings to determine multimodal therapy.
Conclusion
Multidisciplinary management of perioperative patient care has improved outcomes.

Effect of postoperative diclofenac on anastomotic healing, skin wounds and subcutaneous collagen accumulation: a randomized, blinded, placebo-controlled, experimental study. ACTA ACUST UNITED AC 2012; 48:73-8.

Abstract
BACKGROUND Retrospective studies have drawn attention to possible detrimental effects of non-steroidal anti-inflammatory drugs (NSAIDs) on the anastomotic leakage rate after colorectal resection. In this study, we examined the effects of the NSAID diclofenac on the breaking strength of an experimental colonic anastomosis and a skin incision as well as subcutaneous collagen accumulation. METHODS This was a randomized, blinded, placebo-controlled experimental study in 60 male Wistar rats treated with diclofenac 4 mg/kg/day or placebo. In each rat, a colonic anastomosis was performed and an expanded polytetrafluoroethylene (ePTFE) tube was placed subcutaneously. Incisional and anastomotic wound breaking strength and hydroxyproline content in the ePTFE tubes were measured 7 days after the operation. RESULTS We found no significant differences in any of the breaking strength measurements, but showed a median 38% reduction in hydroxyproline deposition as a result of diclofenac treatment (p = 0.03). In the placebo group, subcutaneous collagen deposition tended to correlate positively with skin incisional but negatively with anastomotic bio-mechanical strength. CONCLUSION Postoperative diclofenac treatment significantly inhibited collagen deposition in subcutaneous granulation tissue. Anastomotic strength and skin wound strength were not significantly affected. The ePTFE model is suitable for assessing the effect of various drugs on collagen formation and thus on wound healing.

Abstract
BACKGROUND With the implementation of multimodal analgesia regimens in fast-track surgery programmes, non-steroidal anti-inflammatory drugs (NSAIDs) are being prescribed routinely. However, doubts have been raised concerning the safety of NSAIDs in terms of anastomotic healing. METHODS Data on patients who had undergone primary colorectal anastomosis at two teaching hospitals between January 2008 and December 2010 were analysed retrospectively. Exact use of NSAIDs was recorded. Rates of anastomotic leakage were compared between groups and corrected for known risk factors in both univariable and multivariable analyses. RESULTS A total of 795 patients were divided into four groups according to NSAID use: no NSAIDs (471 patients), use of non-selective NSAIDs (201), use of selective cyclo-oxygenase (COX) 2 inhibitors (79), and use of both selective and non-selective NSAIDs (44). The overall leak rate was 9.9 per cent (10.0 per cent for right colonic, 8.7 per cent for left colonic and 12.4 per cent for rectal anastomoses). Known risk factors such as smoking and use of steroids were not significantly associated with anastomotic leakage. Stapled anastomosis was identified as an independent predictor of leakage in multivariable analysis (odds ratio (OR) 2.22, 95 per cent confidence interval 1.30 to 3.80; P = 0.003). Patients on NSAIDs had higher anastomotic leakage rates than those not on NSAIDs (13.2 versus 7.6 per cent; OR 1.84, 1.13 to 2.98; P = 0.010). This effect was mainly due to non-selective NSAIDs (14.5 per cent; OR 2.13, 1.24 to 3.65; P = 0.006), not selective COX-2 inhibitors (9 per cent; OR 1.16, 0.49 to 2.75; P = 0.741). The overall mortality rate was 4.2 per cent, with no significant difference between groups (P = 0.438). CONCLUSION Non-selective NSAIDs may be associated with anastomotic leakage.

Abstract
PURPOSE Analgesic regimes to avoid opioid-related adverse effects have been recommended in gastrointestinal surgery. Non-steroidal anti-inflammatory drugs (NSAIDs) are an important component of opioid sparing regimes in that these drugs indirectly reduce pain by inhibiting inflammation. Although beneficial for most surgical patients, animal studies and recent clinical studies suggest a harmful effect on new intestinal anastomoses by increasing the rate of leakage. NSAIDs may indirectly disturb anastomotic healing by inhibiting inflammation as an integrated part of the wound healing process in an early, critical phase after surgery. METHODS A literature review based on a structured search in PubMed of clinical and experimental studies investigating the effects of NSAIDs on anastomotic healing and leakage rates after intestinal surgery, as well as proposed mechanisms and effects studied in animal models. RESULTS Three recent observational cohort studies (accumulated n = 882) indicate an increased rate of anastomotic leakages (15-21%) associated with cyclooxygenase-2 (COX-2) selective NSAIDs after intestinal surgery compared to the leakage rates in controls or historical cohorts (1-4%). Three prospective studies on related topics contain relevant data on NSAIDs and are compared to these studies. Several experimental animal studies support an increased risk for anastomotic leakage with the use of NSAIDs. CONCLUSION The reported effects of NSAIDs on anastomotic healing suggest an increased risk for leakage. A better understanding of the complex interactions of NSAID-induced inhibition on anastomotic healing is a prerequisite for the safe use of NSAIDs. Until more data are available, a careful use of NSAIDs may be warranted in gastrointestinal anastomotic surgery.
