RESUMO
BACKGROUND: Emergency laparotomy has high morbidity and mortality rates. Frailty assessment remains underutilized in this setting, in part due to time constraints and feasibility. The Clinical Frailty Scale has been identified as the most appropriate tool for frailty assessment in emergency laparotomy patients and is recommended for all older patients undergoing emergency laparotomy. The prognostic impact of measured frailty using the Clinical Frailty Scale on short- and long-term mortality and morbidity rates remains to be determined. METHODS: Observational cohort studies were identified by systematically searching Medline, Embase, Scopus and CENTRAL databases up to February 2024, comparing outcomes following emergency laparotomy for frail and non-frail participants defined according to the Clinical Frailty Scale. The primary outcomes were short- and long-term mortality rates. A random-effects model was created with pooling of effect estimates and a separate narrative synthesis was created. Risk of bias was assessed. RESULTS: Twelve articles comprising 5704 patients were included. Frailty prevalence was 25% in all patients and 32% in older adults (age ≥55 years). Older patients with frailty had a significantly greater risk of postoperative death (30-day mortality rate OR 3.84, 95% c.i. 2.90 to 5.09, 1-year mortality rate OR 3.03, 95% c.i. 2.17 to 4.23). Meta-regression revealed that variations in cut-off values to define frailty did not significantly affect the association with frailty and 30-day mortality rate. Frailty was associated with higher rates of major complications (OR 1.93, 95% c.i. 1.27 to 2.93) and discharge to an increased level of care. CONCLUSION: Frailty is significantly correlated with short- and long-term mortality rates following emergency laparotomy, as well as an adverse morbidity rate and functional outcomes. Identifying frailty using the Clinical Frailty Scale may aid in patient-centred decision-making and implementation of tailored care strategies for these 'high-risk' patients, with the aim of reducing adverse outcomes following emergency laparotomy.

INTRODUCTION: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a temporizing hemorrhage control intervention, but its inevitable effect on time to operating room (OR) has not been assessed. The aim of our study is to assess the impact of undergoing REBOA before surgery (RBS) on time to definitive hemorrhage control surgery. METHODS: In this retrospective analysis of 2017-2021 ACS-TQIP database, all adult (≥18 years) patients who underwent emergency hemorrhage control laparotomy (≤4 hours of admission) and received early blood products (≤4 hours) were included, and patients with severe head injury (Head-abbreviated injury score > 2) were excluded. Patients were stratified into those who did (RBS) vs those who did not undergo REBOA before surgery (No-RBS). Primary outcome was time to laparotomy. Secondary outcomes were complications and mortality. Multivariable linear and binary logistic regression analyses were performed to identify the independent associations between RBS and outcomes. RESULTS: A total of 32,683 patients who underwent emergency laparotomy were identified (RBS: 342; No-RBS: 32,341). The mean age was 39 (16) years, 78% were male, mean SBP was 107 (34) mmHg, and the median injury severity score was 21 [14-29]. The median time to emergency hemorrhage control surgery was 50 [32-85] minutes. Overall complication rate was 16% and mortality was 19%. On univariate analysis, RBS group had longer time to surgery (RBS 56 [41-89] vs No-RBS 50 [32-85] minutes, P < 0.001). On multivariable analysis, RBS was independently associated with a longer time to hemorrhage control surgery (ß + 14.5 [95%CI 7.8-21.3], P < 0.001), higher odds of complications (aOR = 1.72, 95%CI = 1.27-2.34, P < 0.001), and mortality (aOR = 3.42, 95%CI = 2.57-4.55, P < 0.001). CONCLUSION: REBOA is independently associated with longer time to OR for hemorrhaging trauma patients with an average delay of 15 minutes. Further research evaluating center-specific REBOA volume and utilization practices, and other pertinent system factors, may help improve both time to REBOA as well as time to definitive hemorrhage control across US trauma centers. LEVEL OF EVIDENCE: III. STUDY TYPE: Epidemiologic.

Enterovesical fistula (EVF) in Crohn's disease (CD) often does not improve with medical treatment and requires surgical treatment. The surgical treatment strategy for EVF in CD is definitive resection of the intestinal tract side, and performing a leak test using dye injection into the bladder after EVF dissection to determine the appropriate surgical procedure for the bladder side. This study aimed to evaluate the outcomes of surgical treatment for EVF in CD. Twenty-one patients who underwent surgery for EVF between 2006 and 2021 were included and retrospectively evaluated for clinical background, surgical procedures, and postoperative complications. The most common origin of EVF was the ileum (17 cases; 81%), and the most common site of EVF formation was the apex (12; 57%). Surgical approaches were laparotomy in 11 (52%) cases and laparoscopy in 10 (48%). Surgical procedures on the bladder side were fistula dissection in 13 (62%) cases and sutured closure of fistula in 8 (38%). A comparison of approaches revealed no significant difference in operative time, but the amount of blood loss was significantly less in the laparoscopy (p < 0.01). There was no significant difference in the occurrence of postoperative complications between approaches. Postoperative anti-TNF-α antibody agents were used in 17 (81%) cases, and there were no cases of recurrent EVF. In conclusion, definitive resection of the intestinal tract and minimal treatment on the bladder side were sufficient to achieve satisfactory outcomes for EVF in CD.

BACKGROUND/AIM: There is lack of studies assessing the correlation between pain scales and acute phase immune response (APR) following surgery. The purpose of this work was to assess the correlation between cysteine protease caspase-1 (Casp1) blood levels and two pain scales in a cohort of 56 midline laparotomy (MLa) patients and to assess their link with other cytokines (CYTs). PATIENTS AND METHODS: Blood levels of Casp1 and other CYTs (IL-18, IL-18BP, IL-1ra, IL-6, IL-8, IL-10, IL-1ß) were measured before operation and following surgery in patients with MLa. Pain levels were assessed using the Numerical Rating Scale (NRS) and Brief Pain Inventory (BPI) scale, both preoperatively and postoperatively. RESULTS: Casp1 blood levels showed an increasing trend at postoperative day 1 (POP1) and this increase was almost significant in a linear mixed effect model (LME) analysis (p=0.06). Additionally, Casp1 blood levels were higher in patients with cancer than those with benign disease and correlated with IL-18 blood levels (r=0.24, p=0.007). Furthermore, Casp1 blood levels correlated with BPIsev (severity) score values in MLa patients (r=-0.49, p=0.048). A significant correlation was also observed between Casp1 blood levels and NRS scores in patients with MLa. CONCLUSION: This is the first report to evaluate two pain surveys (NRS and BPI) in MLa patients in relation to blood levels of Casp1 and eight CYTs. This analysis is important in confirming the significant correlation between NRS and BPI pain scales and Casp1 blood levels. Our study is also the first to demonstrate that adequate postoperative analgesia in patients with MLa provides better functional ability and improved patient satisfaction.

BACKGROUND: Patients undergoing emergency laparotomy present with a profound inflammatory response, which could be an independent pathophysiological component in prolonged recovery. The aim of this study was to investigate the effects of a single preoperative high dose of intravenous dexamethasone on the inflammatory response and recovery after emergency laparotomy. METHODS: In this double-blinded placebo-controlled trial, patients were prospectively stratified according to surgical pathology (intestinal obstruction and perforated viscus) and randomized to preoperative 1â mg/kg dexamethasone or placebo at a ratio of 1 : 1. The primary outcome was C-reactive protein on postoperative day 1. Secondary outcomes were postoperative recovery, morbidity, and mortality. RESULTS: A total of 120 patients were included in the trial. On postoperative day 1, the C-reactive protein response was significantly lower in the dexamethasone group (a median of 170 versus 220â mg/l for dexamethasone and for placebo respectively; P = 0.015; mean difference = 49 (95% c.i. 13 to 85)â mg/l) and when stratified according to intestinal obstruction (a median of 60 versus 160â mg/l for dexamethasone and for placebo respectively; P = 0.002) and perforated viscus (a median of 230 versus 285â mg/l for dexamethasone and for placebo respectively; P = 0.035). Dexamethasone administration was associated with improved recovery (better haemodynamics, better pulmonary function, less fatigue, and earlier mobilization). Furthermore, the dexamethasone group had a lower 90-day mortality rate (7% versus 23% for dexamethasone and for placebo respectively; relative risk 0.33 (95% c.i. 0.11 to 0.93); P = 0.023) and a decreased incidence of postoperative major complications (27% versus 45% for dexamethasone and for placebo respectively; relative risk 0.62 (95% c.i. 0.37 to 1.00); P = 0.032). CONCLUSION: A single preoperative high dose of intravenous dexamethasone significantly reduces the inflammatory response after emergency laparotomy and is associated with enhanced recovery and improved outcome.

INTRODUCTION: Damage-control laparotomy has been widely used in general surgery. However, associated surgical-site infection risks have rarely been investigated. Damage-control laparotomy allows for additional opportunities for decontamination. We hypothesized that damage-control laparotomy would be associated with lower surgical-site infection risks compared with laparotomy with only primary fascial closure or with primary fascial and skin closure. METHODS: Patients admitted for emergent intestinal surgery from 2006 to 2021 were included. Multivariate analyses were performed to identify surgical-site infection-associated risk factors. Although variables like laparotomy type (damage-control laparotomy, primary fascial closure, and primary fascial and skin closure) were provided by National Surgical Quality Improvement Program, other variables such as number of operations were retrospectively collected. P < .05 was considered significant. RESULTS: Overall, 906 patients were included; 213 underwent damage-control laparotomy, 175 primary fascial closure, and 518 primary fascial and skin closure. Superficial, deep, and organ-space surgical-site infection developed in 66, 6, and 97 patients, respectively. Compared with primary fascial and skin closure, both damage-control laparotomy (odds ratio, 0.30 [95% CI, 0.13-0.73], P = .008) and primary fascial closure (odds ratio, 0.09 [95% CI, 0.02-0.37], P = .001) were associated with lower superficial incisional surgical-site infection but not organ-space surgical-site infection risk (odds ratio, 0.80 [95% CI, 0.29-2.19] P = .667 and odds ratio, 0.674 [95% CI, 0.21-2.14], P = .502, respectively). Body mass index was associated with increased risk of superficial incisional surgical-site infection (odds ratio, 1.06 [95% CI, 1.03-1.09], P < .001) whereas frailty was associated with organ space surgical-site infection (odds ratio, 3.28 [95% CI, 1.29-8.36], P = .013). For patients who underwent damage-control laparotomy, the number of operations did not affect risk of either superficial incisional surgical-site infection or organ space SSI. CONCLUSION: Herein, compared with primary fascial and skin closure, both damage-control laparotomy and primary fascial closure were associated with lower superficial but not organ space surgical-site infection risks. For patients who underwent damage-control laparotomy, number of operations did not affect surgical-site infection risks.

BACKGROUND: Textbook outcomes are composite outcome measures that reflect the ideal overall experience for patients. There are many of these in the elective surgery literature but no textbook outcomes have been proposed for patients following emergency laparotomy. The aim was to achieve international consensus amongst experts and patients for the best Textbook Outcomes for non-trauma and trauma emergency laparotomy. METHODS: A modified Delphi exercise was undertaken with three planned rounds to achieve consensus regarding the best Textbook Outcomes based on the category, number and importance (Likert scale of 1-5) of individual outcome measures. There were separate questions for non-trauma and trauma. A patient engagement exercise was undertaken after round 2 to inform the final round. RESULTS: A total of 337 participants from 53 countries participated in all three rounds of the exercise. The final Textbook Outcomes were divided into 'early' and 'longer-term'. For non-trauma patients the proposed early Textbook Outcome was 'Discharged from hospital without serious postoperative complications (Clavien-Dindo ≥ grade III; including intra-abdominal sepsis, organ failure, unplanned re-operation or death). For trauma patients it was 'Discharged from hospital without unexpected transfusion after haemostasis, and no serious postoperative complications (adapted Clavien-Dindo for trauma ≥ grade III; including intra-abdominal sepsis, organ failure, unplanned re-operation on or death)'. The longer-term Textbook Outcome for both non-trauma and trauma was 'Achieved the early Textbook Outcome, and restoration of baseline quality of life at 1 year'. CONCLUSION: Early and longer-term Textbook Outcomes have been agreed by an international consensus of experts for non-trauma and trauma emergency laparotomy. These now require clinical validation with patient data.

BACKGROUND: The high rate of stoma placement during emergency laparotomy for secondary peritonitis is a paradigm in need of change in the current fast-track surgical setting. Despite growing evidence for the feasibility of primary bowel reconstruction in a peritonitic environment, little data substantiate a surgeons' choice between a stoma and an anastomosis. The aim of this retrospective analysis is to identify pre- and intraoperative parameters that predict the leakage risk for enteric sutures placed during source control surgery (SCS) for secondary peritonitis. METHODS: Between January 2014 and December 2020, 497 patients underwent SCS for secondary peritonitis, of whom 187 received a primary reconstruction of the lower gastro-intestinal tract without a diverting stoma. In 47 (25.1%) patients postoperative leakage of the enteric sutures was directly confirmed during revision surgery or by computed tomography. Quantifiable predictors of intestinal suture outcome were detected by multivariate analysis. RESULTS: Length of intensive care, in-hospital mortality and failure of release to the initial home environment were significantly higher in patients with enteric suture leakage following SCS compared to patients with intact anastomoses (p < 0.0001, p = 0.0026 and p =0.0009, respectively). Reduced serum choline esterase (sCHE) levels and a high extent of peritonitis were identified as independent risk factors for insufficiency of enteric sutures placed during emergency laparotomy. CONCLUSIONS: A preoperative sCHE < 4.5 kU/L and generalized fecal peritonitis associate with a significantly higher incidence of enteric suture insufficiency after primary reconstruction of the lower gastro-intestinal tract in a peritonitic abdomen. These parameters may guide surgeons when choosing the optimal surgical procedure in the emergency setting.

Surgical site infection (SSI) is a common complication after celiotomy in horses, leading to increased morbidity and costs. Increased concern about antibiotic resistance justifies evaluation of alternative preventive approaches, such a Manuka honey which has displayed antimicrobial properties. Pectin-Honey Hydrogels (PHH), composed by Manuka honey and pectin provide a moist wound environment and microbial growth inhibition. The aim of the study was to evaluate the effectiveness of PHHs in preventing SSI in horses subjected to emergency laparotomy. Horses undergoing laparotomy were evaluated. Horses were randomly divided into two groups: Group 1 received PHH application onto the sutured linea alba before skin closure, while Group 2 received no treatment. Horses with postoperative antimicrobial administration or survival of less than 5 days were excluded. The incidence of SSIs was reported as percentages and compared between groups. Out of 44 horses enrolled in the study, only thirty-six were ultimately included. Exclusions occurred either due to death before 5 days postoperatively (2 horses) or the administration of postoperative antimicrobials (6 horses). The median length of hospitalization was 9 days (range 8-14 days). The overall occurrence of SSI was 19.4 %. One out of eighteen horses (5.5 %) in Group 1 and 6 out of 18 (33.3 %) horses in Group 2 developed SSI. Group 2 had an 8.5-fold increased risk of SSI (p = 0.035, OR = 8.5, 95 % CI. 0.9-80.07). No macroscopically visible adverse reactions were associated with PHH. PHH placed at the abdominal incision during surgery was safe and reduced the prevalence of SSI in horses.

INTRODUCTION: Postoperative Ileus (POI) negatively impacts patient outcomes and increases healthcare costs. Transcutaneous electrical nerve stimulation (TENS) has been found to improve gastrointestinal (GI) motility following abdominal surgery. However, its effectiveness in this context is not well-established. This study was designed to evaluate the role of TENS on the recovery of GI motility after exploratory laparotomy. METHODS: Patients undergoing exploratory laparotomy were randomized in a 1:1 ratio into control (standard treatment alone) and experimental (standard treatment + TENS) arms. TENS was terminated after 6 days or after the passage of stool or stoma movement. The primary outcome was time for the first passage of stool/functioning stoma. Non-passage of stool or nonfunctioning stoma beyond 6 days was labeled as prolonged POI. Patients were monitored until discharge. RESULTS: Median (interquartile range) time to first passage of stool/functioning stoma was 82.6 (49-115) hours in the standard treatment group and 50 (22-70.6) hours in the TENS group [p < 0.001]. Prolonged POI was noted in 11 patients in the standard treatment group (35.5%) and one in the TENS group (3.2%) [p = 0.003]. Postoperative hospital stay was similar in the two groups. CONCLUSION: TENS resulted in early recovery of GI motility by shortening the duration of POI without any improvement in postoperative hospital stay. TRIAL REGISTRATION NUMBER: CTRI/2021/10/037054.

Although rarely fatal, complications of ventral midline laparotomy incision in equine patients increase hospitalization cost and duration and may jeopardize return to athletic function. Therefore, many techniques have been developed to reduce their occurrence and expedite their resolution when they occur. Our technique of celiotomy incision closure includes the use of tension sutures (vertical U mattress) of polyglactin 910 on the linea alba, which is then apposed by polyglactin 910 interrupted sutures or a simple continuous pattern suture with a stop midway before routine closure of the superficial layers. The celiotomy incision is protected by an elastic bandage during the immediate postoperative period. This technique has been associated with favorable results: 5.3% confirmed incisional infections after a single celiotomy and 26.7% after repeat celiotomy. The overall incisional complication (serous/sanguineous discharge, hematoma, infection, hernia formation, and complete wound breakdown) occurrence was 9.5% and 33.3% after single and repeat laparotomy, respectively. In cases considered more susceptible to infection (early relaparotomy or laparotomy incisions longer than 30 cm), negative pressure therapy was found easy to apply on closed incisions. No detrimental effects were observed. However, the potential prophylactic benefit of this therapy needs to be confirmed in a larger group. In infected laparotomy wounds requiring drainage, the use of negative pressure therapy seemed to have a positive effect on the formation of granulation tissue. However, there was no control group to allow statistical confirmation. Finally, one case of complete breakdown of the laparotomy incision was managed by stainless steel retention sutures, the application of negative pressure therapy, and a hernia belt. At re-evaluation 15 months post-surgery, several small hernias were detected, but the horse had returned to his previous level of sports performance and had not shown any episode of colic.

OBJECTIVE: To determine the effect of a single intraoperative dose of dexamethasone on the risk of postoperative reflux (POR) in horses undergoing small intestinal surgery and to investigate its association with incisional complications and short-term survival. DESIGN: Retrospective cohort study over an 11-year period (2008-2019). SETTING: UK-based private referral center. ANIMALS: Two hundred and forty client-owned horses >6 months of age undergoing exploratory laparotomy for treatment of a small intestinal lesion. INTERVENTIONS: Ninety-seven horses received a single intraoperative dose of dexamethasone (0.1 mg/kg, IV). MEASUREMENTS AND MAIN RESULTS: Of 97 horses that received dexamethasone, 52 (53.6%) required small intestinal resection. Of 143 horses that did not receive dexamethasone, small intestinal resection was performed in 78 (54.5%). A total of 70 horses (29%) developed POR. There was no difference in the risk of POR between horses that received dexamethasone (25/97; 26%) and those that did not (45/143; 31%, P = 0.34). Risk factors associated with the development of POR included small intestinal resection (odds ratio [OR]: 4.55, 95% confidence interval [CI]: 2.27-9.11, P < 0.001), a PCV >40% 24 hours postoperatively (OR: 4.11, 95% CI: 2-8.45, P < 0.001), and a WBC count >10 × 109/L on admission (OR: 3.29, 95% CI: 1.47-7.41, P = 0.004). Dexamethasone was not associated with the odds of POR. Horses undergoing repeat laparotomy had a higher risk of incisional infection (OR: 8.07, 95% CI: 1.98-32.81, P = 0.004). Dexamethasone administration was not associated with incisional infection. The development of POR was negatively associated with short-term survival (OR: 0.07, 95% CI: 0.03-0.17, P ≤ 0.001). Dexamethasone administration was not retained in the final multivariable model for survival. CONCLUSIONS: Intraoperative dexamethasone was not associated with the development of POR in this study population, nor did it have an effect on postoperative survival or incisional infection in horses undergoing surgical management of small intestinal disease.

Anesthesia and surgery activate matrix metalloproteinase 9 (MMP9), leading to blood-brain barrier (BBB) disruption and postoperative delirium (POD)-like behavior, especially in the elderly. Aged mice received intraperitoneal injections of either the MMP9 inhibitor SB-3CT, melatonin, or solvent, and underwent laparotomy under 3 % sevoflurane anesthesia(anesthesia/surgery). Behavioral tests were performed 24 h pre- and post-operatively. Serum and cortical tissue levels of interleukin (IL)-1ß, IL-6, and tumor necrosis factor-α (TNF-α) were measured using ELISA. Levels of PDGFRß, MMP9, tight junction, Mfsd2a, caveolin-1, synaptophysin, and postsynaptic densin (PSD)-95 proteins in the prefrontal cortex were assayed using Western blotting. BBB permeability was assessed by detecting IgG in the prefrontal cortex and serum S100ß levels. Anesthesia/surgery-induced peripheral inflammation activated MMP9, which in turn injured pericytes and tight junctions and increased transcytosis, thereby disrupting the BBB. Impaired BBB allowed the migration of peripheral inflammation into the central nervous system (CNS), thereby inducing neuroinflammation, synaptic dysfunction, and POD-like behaviors. However, MMP9 inhibition reduced pericyte and tight junction injury and transcytosis, thereby preserving BBB function and preventing the migration of peripheral inflammation into the CNS, thus attenuating synaptic dysfunction and POD-like behavior. In addition, to further validate the above findings, we showed that melatonin exerted similar effects through inhibition of MMP9. The present study shows that after anesthesia/surgery, inflammatory cytokines upregulation is involved in regulating BBB permeability in aged mice through activation of MMP9, suggesting that MMP9 may be a potential target for the prevention of POD.

OBJECTIVE: To evaluate the efficacy of negative pressure therapy in patients with peritonitis. MATERIAL AND METHODS: The study included 127 patients with advanced secondary peritonitis between 2019 and 2022. All patients were divided into 2 groups. All ones underwent staged sanitation of the abdominal cavity. In the first group (n=76), re-laparotomies were accompanied by skin suture only and passive abdominal drainage. The second group included patients (n=51) with open abdominal cavity strategy and negative pressure therapy (vacuum-assisted laparostomy). We analyzed the number of surgeries, postoperative complications, duration of hospital-stay and mortality. RESULTS: In the second group, there were significantly lower morbidity, mean number of surgeries and hospital-stay. In addition, incidence of fascial closure of abdominal cavity was higher and mortality rate was lower in the same group. CONCLUSION: Vacuum-assisted laparostomy in patients with advanced peritonitis can reduce the number of secondary purulent complications and mortality, as well as increase the incidence of fascial closure of abdominal cavity. This approach reduces the number of surgical interventions and duration of in-hospital treatment.

Objective: To explore the relationship between gut microbiota and its metabolite dysregulation and postoperative cognitive dysfunction in elderly male C57BL/6J mice after laparotomy exploration. Methods: A total of 48 specific pathogen-free (SPF) male C57BL/6J mice, aged 16-17 months, were divided into two groups by random number table method: control group (n=24) and operation group (n=24). Mice in the operation group were induced with 1.4% isoflurane for 15 minutes, followed by a 10 minutes exploratory laparotomy anesthetized with 1.4% isoflurane and 100% oxygen, and anesthesia continued for 2 hours after surgery. Mice in control group were put in 100% oxygen for 2 hours. Feces and venous blood samples of both groups were collected 48 hours after surgery. Changes in the abundance and diversity of intestinal bacteria in the feces were detected by 16S rDNA gene sequencing. Functional changes of fecal metabolic profiles were detected by liquid chromatography tandem mass spectrometry (LC/MS) metabolomics and differential metabolite functions were analyzed. The serum level of interleukin (IL)-6, IL-1ß and tumor necrosis factor-α (TNF-α) were detected by Enzyme-linked immunosorbent assay (ELISA). The cognitive function of the mice was detected by Morris water maze test 3 days after operation. Results: The postoperative escape latency of mice in control group and operation group was (22.0±4.9) and (35.0±5.1) s, and the target quadrant residence time was (26.0±3.7) and (16.0±2.9) s, respectively. Compared with the control group, the postoperative escape latency of mice in the operation group was prolonged (P=0.035), and the residence time in the target quadrant was reduced (P=0.006). The difference of intestinal flora between the two groups was comparable. The expression levels of Escherichia coli, shigella and clostridium in the operation group were up-regulated, while the expression levels of rumen bacteria and butyricobacteria were down-regulated. Fecal metabolic profiles of mice in control group and operation group were obtained by LC/MS, and 14 and 21 different metabolites were screened in positive and negative ion modes, respectively. The different metabolites in positive ion mode were glutamic acid, 2-indoleic acid, kynuuric acid and glyceraldehyde. The negative ion pattern differential metabolites are methionine, aspartic acid, L-threonine, tyrosyl-threonine and 5-hydroxyindole-3-acetic acid. The identified differential metabolite pathways are mainly involved in amino acid, fatty acid and tryptophan metabolism and nucleotide synthesis. There were no significant differences in serum levels of IL-1ß, IL-6 and TNF-α between the two groups (all P>0.05). Conclusion: The dysregulated changes of gut microbiota and its metabolites are correlated with the occurrence of postoperative cognitive dysfunction in elderly male C57BL/6J mice. Anesthesia and surgery alter the structure of mice intestinal bacteria on the level of abundance, and change the metabolic balance and feces metabolomic phenotype.

Myomectomy is one of the most common surgical procedure in the field of gynecology. However, the role of laparoscopic myomectomy is still debated for many factors, including surgical considerations, safety and fertility concerns, long-term outcomes, and cost-related issues. The aim of this study is to evaluate the surgical peri- and post-operative outcomes of laparoscopic and abdominal myomectomy. A systematic search for studies was performed up to June 2023 through MEDLINE, Pubmed, Embase. Studies reporting the comparison of surgical and obstetrical outcomes in laparoscopic versus laparotomic myomectomy were included for the following outcomes: time of surgery, estimated blood loss, decrease of postoperative hemoglobin, hospital stay, intra-operative complication rates, postoperative complications rates, postoperative analgesic use, postoperative pain at 24 h and pregnancy rate. The meta-analysis was performed using the Cochrane Review software. Fifty-six relevant articles were retrieved through the process of evidence acquisition. Eleven articles met inclusion criteria, for a total of 2,133 patients undergoing laparoscopic or laparotomic myomectomy. The estimated blood loss [standard mean differences (SMD) 0.72, IC 95 % 0.22 to 1.22], the hospital stays [SMD 3.12, IC 95 % 0.57 to 4.28], were significantly lower in laparoscopic than in open group. No statistically significant difference in intra-operative and post-operative complication rates, in pregnancy rate and others obstetrical outcomes between two surgical approaches were found. The findings of present metanalysis suggest that laparoscopic myomectomy offers multiple benefits, including reduced blood loss, shorter hospital stays, and less postoperative analgesic need, without a significant increase in complication rates and similar results in obstetrical outcomes when compared to abdominal myomectomy. However, the presence of few randomized studies on selected population may limit the generalizability of the findings to the entire population. Therefore, more well-designed studies or large population programdata to draw definitive conclusions are therefore warranted.

An increased intra-abdominal pressure can result in a manifest abdominal compartment syndrome (ACS) with significant organ damage, which is a life-threatening situation associated with a high mortality. Although the etiology is manifold and critically ill patients on the intensive care unit are particularly endangered, the disease is often not diagnosed even though the measurement of bladder pressure is available as a simple and standardized method; however, particularly the early detection of an increased intra-abdominal pressure is decisive in order to prevent the occurrence of a manifest ACS with (multi)organ failure by means of conservative measures. In cases of a conservative refractory situation, decompressive laparotomy is indicated.

INTRODUCTION: Emergent laparotomy is associated with significant wound complications including surgical site infections (SSIs) and fascial dehiscence. Triclosan-coated barbed (TCB) suture for fascial closure has been shown to reduce local complications but primarily in elective settings. We sought to evaluate the effect of TCB emergency laparotomy fascial closure on major wound complications. METHODS: Adult patients undergoing emergency laparotomy were prospectively evaluated over 1 year. Patients were grouped into TCB versus polydioxanone (PDS) for fascial closure. Subanalysis was performed on patients undergoing single-stage laparotomy. Primary outcomes were SSI and fascial dehiscence. Multivariate analysis identified independent factors associated with SSI and fascial dehiscence. RESULTS: Of the 206 laparotomies, 73 (35%) were closed with TCB, and 133 (65%) were closed with PDS. Trauma was the reason for laparotomy in 73% of cases; damage-control laparotomy was performed in 27% of cases. The overall rate of SSI and fascial dehiscence was 18% and 10%, respectively. Operative strategy was similar between groups, including damage-control laparotomy, wound vac use, skin closure, and blood products. Surgical site infection events trended lower with TCB versus PDS closure (11% vs. 21%, p = 0.07), and fascial dehiscence was significantly lower with TCB versus PDS (4% vs. 14%, p < 0.05). Subanalysis of trauma and nontrauma cases showed no difference in SSI or fascial dehiscence. Multivariable analysis found that TCB decreased the likelihood of fascial dehiscence (odds ratio, 0.07; p < 0.05) following emergency laparotomy. Increased odds of fascial dehiscence were seen in damage-control laparotomy (odds ratio, 3.1; p < 0.05). CONCLUSION: Emergency laparotomy fascial closure with TCB showed significantly decreased rates of fascial dehiscence compared with closure with PDS and a strong trend toward lower SSI events. Triclosan-coated barbed suture was independently associated with decreased fascial dehiscence rates after emergency laparotomy. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

This study aimed to investigate the effect of laparoscopic and laparotomy extensive hysterectomy on the safety of ureterovaginal fistula infection in patients with cervical cancer. For this purpose, a total of 90 patients with early cervical cancer admitted to Affiliated Huaian No.1 People's Hospital of Nanjing Medical University from February 2021 to May 2022 were randomly divided into laparoscopy group and laparotomy group, with 45 cases in each group. The laparoscopy group was treated with laparoscopic extensive hysterectomy, while the laparotomy group was treated with laparotomy extensive hysterectomy. The KPS score, adverse reactions, as well as serum creatinine and urea nitrogen were compared between the two groups. Results showed that after surgery, the KPS score in both groups was higher than before treatment, and the KPS score in laparoscopy group was higher than that in laparotomy group, the difference was statistically significant (P<0.05). After operation, the incidence of adverse reactions in laparotomy group was higher than that in the laparoscopy group, the difference was statistically significant (P<0.05). Moreover, after operation, the levels of creatinine and urea nitrogen in laparoscopy group were significantly lower than those in laparotomy group, the differences were statistically significant (P<0.05). In conclusion, both laparoscopic and laparotomy extensive hysterectomy may lead to ureterovaginal fistula infection in patients with cervical cancer. However, compared with laparotomy extensive hysterectomy, laparoscopic extensive hysterectomy had higher safety and significantly improved the quality of life of patients, which was worthy of popularization and application in clinical practice.

Aberrant activation of complement cascades plays an important role in the progress of neurological disorders. Complement C3, the central complement component, has been implicated in synaptic loss and cognitive impairment. Recent study has shown that wound injury-induced systemic inflammation can trigger the increase of C3 in the brain. Our previous studies have demonstrated that laparotomy-triggered systemic inflammation could induce neuroinflammation and cognitive dysfunctions. Furthermore, sustained activation of microglia was observed even 14 days after laparotomy, while most of cytokines had returned to basal levels rapidly at the earlier time point. Although we have demonstrated that anti-inflammatory intervention successfully attenuated cognitive dysfunction by preventing increase of cytokines and activation of microglia, how sustained activation of microglia and cognitive dysfunction occur is still a mystery. In this study, we investigated the role of C3 in mediating activation of microglia and cognitive dysfunction by using laparotomy in adult male mouse only as the experimental model of systemic inflammation and AAV9-C3shRNA. Our data observed that laparotomy induced neurotoxic reactive astrocytes with an increase of C3 in the hippocampus. Furthermore, inhibition of C3 by AAV9-C3shRNA prevented synaptic engulfment by microglia and attenuated cognitive dysfunctions after laparotomy. Inhibition of C3 did not modulate activation of astrocytes and expression of various cytokines. Current findings demonstrated that C3 plays significant roles in sustained activation of microglia and cognitive dysfunctions, which suggests that C3 is the valuable molecule target to attenuate in neurological conditions characterised by neuroinflammation and cognitive dysfunction.
