The role of prehabilitation in reducing the incidence of postoperative pulmonary complications in patients undergoing elective cardiac surgery: Results from the Pre Surgery Check Team study.

Despite its importance, prehabilitation, has only been implemented in very few cardiac surgery centers. The Pre Surgery Check Team study was designed to evaluate the impact of comprehensive interdisciplinary assessment and implementation of the prehabilitation program on the incidence of postoperative pulmonary complications after elective cardiac surgery. 725 adult patients (338 in the study group, 387 in the control group) were included in this single-center, prospective, observational study. Multimodal prehabilitation consisted of four elements: interdisciplinary medical assessment by cardiologist, anesthesiologist and cardiac surgeon, pulmonary assessment for patients at high risk of postoperative pulmonary complications, psychological assessment, and physiotherapeutic assessment and training. The primary endpoint was the occurrence of the postoperative pulmonary complications, and the secondary outcomes were: surgical site infection, rethoracotomy, ICU length of stay and hospital length of stay. Prehabilitation reduced the number of postoperative complications by 23%. Postoperative pneumonia was almost 3 times less common (5.33% vs 14.21%), and the surgical site infection - 1.4 times less common in the PreScheck group (8.28 vs 11.37%). In the logistic regression model, prehabilitation reduced the odds of postoperative pneumonia (by 0.346) and the odds of respiratory failure (by 0.479). Prehabilitation had no direct effect on ICU length of stay. Prehabilitation according to the Pre Surgery Check Team standard reduces the incidence of postoperative pulmonary complications and the total number of postoperative complications in patients undergoing elective cardiac surgery. The main benefit of attending the PreScheck Team visit is the opportunity to perform supportive preoperative interventions.

Retrospective analysis of immediate and long-term results of NOSES technique and conventional laparoscopic-assisted resection in patients with colorectal cancer.

The aim of research was to study the feasibility and safety of surgery providing specimen extraction through natural orifices in patients with colorectal cancer. This study is a comparative retrospective analysis of findings obtained from 265 patients who underwent surgical treatment using NOSES technique and 275 patients who underwent laparoscopic-assisted (LA) resection. Data included preoperative patients' information, intraoperative findings, results of postoperative pathological examination of surgical specimens, early postoperative period analysis, and follow-up. Both groups were comparable in terms of gender, age and BMI. The duration of surgery was similar in both groups (p = 0.94). Intraoperative blood loss under NOSES interventions was slightly lower than in laparoscopic-assisted surgeries (p < 0.001). There was no significant difference in the number of lymph nodes removed and anal function scores between the two groups (p > 0.05). It was revealed that in the NOSES group, the function of the gastrointestinal tract normalized at an earlier time, slightly the time to start liquid food intake and the duration of postoperative hospital stay were reduced (p < 0.001). A statistically significant difference between groups was found in complications, such as pneumonia (p = 0.03). The absolute number of complications was observed more often in the LA surgery group (10.4%) than in the NOSES group (5.8%). Local recurrence was less common in the NOSES group (p = 0.01). There were no statistically significant differences in disease progression (p = 0.16). When analyzing disease-free and overall survival rate in this study, there was no statistically significant difference between the two surgical techniques in terms of their effect on postoperative survival (p > 0.05). The results of this study demonstrate that NOSES technique is a relatively safe and effective surgical option in patients with colorectal cancer. It has high surgical efficiency providing no increased risk of surgical intervention, reducing total number of postoperative complications, reducing duration of postoperative hospital stay, reducing the time for gastrointestinal function recovery and the start of food intake. This study supports that NOSES has clear advantages over conventional laparoscopic-assisted surgery.

Incidence and Outcomes of Posterior Circulation Involvement in Moyamoya Disease.

Moyamoya disease (MMD) is a progressive, occlusive disease of the internal carotid arteries and their proximal branches, with the subsequent development of an abnormal vascular network that is rupture-prone. Steno-occlusive changes in the posterior cerebral arteries (PCAs) may contribute to worsened outcomes in patients with MMD; however, there is little information on the incidence and natural history of posterior circulation MMD (PCMMD). We describe clinical PCMMD characteristics in a large cohort of patients with MMD. We retrospectively reviewed patients with MMD treated between 1991 and 2019 at a large academic medical center. Demographics, perioperative outcomes, and radiological phenotypes were recorded for 770 patients. PCA disease was graded as either 0 (no disease), 1 (mild), 2 (moderate), or 3 (severe or occluded) based on cerebral angiography. Patients with angiographically confirmed MMD diagnosis with at least 6 months follow-up and completion of revascularization surgery were included; patients with intracranial atherosclerosis, intracranial dissection, vasculitis, and undefined inflammatory processes were excluded. The presence of stenosis/occlusion was graded radiographically to assess for disease progression and the prevalence of risk factors related to reduced progression-free survival. In all, 686 patients met the inclusion criteria, with PCA disease identified in 282 (41.1%) patients. Of those 282 patients with PCMMD, disease severity ranged from 99 (35.1%) with mild, 72 (25.5%) with moderate, and 111 (39.4%) with severe. The total number of postoperative complications was significantly associated with PCMMD severity (P=0.0067). Additionally, PCMMD severity correlated with worse postoperative modified Rankin Scale scores (P<0.0001). At a mean follow-up of 6.0±3.9 (range, 0.1-25.0) years, a total of 60 (12.6%) patients showed new/worsening PCMMD. The overall postoperative, progression-free survival in patients with PCMMD was 95.4% at 1 year, 82.4% at 3 years, 68.8% at 5 years, and 28.3% at 10 years, with prognostic factors for progression including preoperative PCMMD status, history of tobacco use, and hypertension (P<0.0001, P<0.001, and P<0.0001, respectively). PCA disease involvement in MMD is associated with higher rates of ischemic perioperative complications and worsened functional outcomes, likely due to reduced collateral flow. Ten-year progression of PCA disease is highly likely and should be monitored throughout follow-up; future studies will assess the impact of PCA disease progression on long-term outcomes.

The Effect of Diabetes on Complications after Spinal Fusion: A Systematic Review and Meta-Analysis

ObjectiveSpinal fusion procedures are used to treat a wide variety of spinal pathologies. Diabetes mellitus (DM) has been shown to be a significant risk factor for several complications following these procedures in previous studies. To the authors’ knowledge, this is the first systematic review and meta-analysis elucidating the relationship between DM and complications occurring after spinal fusion procedures. MethodsSystematic literature searches of PubMed and EMBASE were performed from their inception to October 1, 2022, to identify studies that directly compared postfusion complications in patients with and without DM. Studies met the prespecified inclusion criteria if they reported the following data for patients with and without DM: (1) demographics; (2) postspinal fusion complication rates; and (3) postoperative clinical outcomes. The included studies were then pooled and analyzed. ResultsTwenty-eight studies, with a cumulative total of 18,853 patients (2,695 diabetic patients), were identified that met the inclusion criteria. Analysis showed that diabetic patients had significantly higher rates of total number of postoperative complications (odds ratio[OR]=1.33;95% confidence interval[CI]=1.12-1.58;p=.001), postoperative pulmonary complications (OR=2.01;95%CI=1.31-3.08;p=.001), postoperative renal complications (OR=2.20;95%CI=1.27-3.80;p=.005), surgical site infection (OR=2.65;95%CI=2.19-3.20;p<.001), and prolonged hospital stay (OR=1.67; 95%CI=1.47-1.90; p<.001). ConclusionsPatients with DM had a significantly higher risk of developing complications after spinal fusion, particularly pulmonary and renal complications, in addition to surgical site infections and had a longer length of stay. These findings are important for informed discussions of surgical risks with patients and families before surgery.

Preoperative Chronic Inflammation Is a Risk Factor for Postoperative Complications Independent of Body Composition in Gastric Cancer Patients Undergoing Radical Gastrectomy.

The purpose of this study was to investigate the association between preoperative inflammation and postoperative complications in gastric cancer patients having elective gastrectomy. Participants in this study were those who underwent radical gastrectomy between April 2008 and June 2018 and were diagnosed with stage I-III primary gastric cancer. Preoperative CRP values were used to divide the patients into two groups: the inflammation group comprised individuals having a CRP level of ≥0.5 mg/dL; the other was the non-inflammation group. The primary outcome was overall complications of Clavien-Dindo grade II or higher after surgery. Using propensity score matching to adjust for background, we compared the postoperative outcomes of the groups and conducted a multivariate analysis to identify risk variables for complications. Of 951 patients, 852 (89.6%) were in the non-inflammation group and 99 (10.4%) were in the inflammation group. After matching, both groups included 99 patients, and no significant differences in patient characteristics were observed between both groups. The inflammation group had a significantly greater total number of postoperative complications (p = 0.019). The multivariate analysis revealed that a preoperative CRP level of ≥0.5 mg/dL was an independent risk factor for total postoperative complications in all patients (odds ratio: 2.310, 95% confidence interval: 1.430-3.730, p < 0.001). In conclusion, in patients undergoing curative resection for gastric cancer, preoperative inflammation has been found to be an independent risk factor for overall complications after surgery. Patients with chronic inflammation require preoperative treatment to reduce inflammation because chronic inflammation is the greatest risk factor for postoperative complications.

Advantages of using a polymeric clip versus an endoloop during laparoscopic appendectomy in uncomplicated appendicitis: a randomized controlled study

BackgroundPolymeric clips are easy to apply, but whether they present more advantages than endoloops is unclear. This single-center, open-label, randomized controlled trial study was conducted to compare the advantages of using a polymeric clip versus an endoloop in terms of the surgical time.MethodsAdult patients who were diagnosed with acute appendicitis without perforation on preoperative abdominal computed tomography and underwent laparoscopic appendectomy between August 6, 2019, and December 26, 2022, were included. Single-blinded randomization was performed in a 1:1 ratio between the endoloop and polymeric clip groups. The primary endpoint was the difference in surgery time between the polymeric clip and endoloop groups. The secondary endpoints were the difference in the application time of each instrument, difference in operation and anesthesia fees, as well as the frequency of complications.ResultsThe completed trial included 104 and 103 patients in the polymeric clip and endoloop groups, respectively. The median surgery time with a polymeric clip was shorter than that with an endoloop; however, the difference was not significant (18 min 56 s vs 19 min 49 s, p = 0.426). Interestingly, the median time from applying the instrument to appendiceal cutting in the polymeric clip group was significantly shorter than that in the endoloop group (49.0 s vs 84.5 s, p < 0.001). No significant difference was observed between the two groups in terms of surgical (p = 0.120) and anesthetic (p = 0.719) costs, as well as the total number of postoperative complications (p > 0.999).ConclusionA polymeric clip is a safe instrument that can reduce the time from applying the instrument to appendiceal cutting, although it does not affect the overall surgical time and operation fee when performing laparoscopic appendectomy for uncomplicated appendicitis.Trial registration: KCT0004154.

Early postoperative complications and their measures after skull base reconstruction: A study from the standpoint of plastic and reconstructive surgeons

ObjectiveIn skull base surgery, postoperative complications may be lethal and it is important to know how to deal with these. There are several reports on complications after skull base reconstruction, but it is difficult to understand which are important for plastic surgeons in charge of reconstruction. The objective of this study is to clarify the early postoperative survival-related complications after skull base reconstruction of which plastic surgeons should participate in treatment. MethodsOne hundred and seventy-seven patients who underwent skull base reconstruction at our department over the last 12 years were retrospectively surveyed. The cases of early complications in which plastic surgeons were actively involved in treatment were investigated and the preventive measures actually taken at our facility are examined in addition to treatment methods after development. ResultsPlastic surgical complications were wound infection in seven patients, impaired blood flow in transplanted tissue in two patients, cerebrospinal fluid leakage in five patients, and intracranial compression in three patients. Total number of postoperative complications were seventeen and the total complication rate was 9.6%. Complication rates tended to be higher in anterior-middle skull base cases than in anterior or middle alone cases and higher with free tissue transfer than with locoregional flap. Multivariate analysis revealed that operation time was a significantly higher risk factor (p=0.012) and preoperative chemotherapy was a significantly lower risk factor (p=0.033) for the development of complications. It was also found that the hospitalization length was significantly longer when complications occurred (p<0.0001). Wound infection was treated with removal of the cause, sufficient drainage, and irrigation. Regarding preventive measures, it is necessary to pay attention especially to intracranial contamination with epithelial components. Rapid surgical measures were necessary when blood flow of the transplanted tissue was impaired. For pedicle flaps, conservation of the feeding vessel is needed, and for free flaps, reliable vascular anastomosis is needed as preventive measures. Plastic surgeons play a role in reducing the risk of cerebrospinal fluid leakage through covering the repaired dura mater with tissue with favorable blood flow, especially in reoperation after development of leakage. Skull base reconstruction with soft tissue may cause intracranial compression, and sometimes, it is not resolved by conservative treatment and reoperation is selected. ConclusionPlastic surgical postoperative complications were clarified, and treatment methods and preventive measures for them were examined. Careful consideration of blood flow, placement, and volume of the transplanted flap is important to prevent complications.

The impact of Enhanced Recovery after Surgery (ERAS) pathways with regard to perioperative outcome in patients with ovarian cancer

PurposeMajor surgery for ovarian cancer is associated with significant morbidity. Recently, guidelines for perioperative care in gynecologic oncology with a structured “Enhanced Recovery after Surgery (ERAS)” program were presented. Our aim was to evaluate if implementation of ERAS reduces postoperative complications in patients undergoing extensive cytoreductive surgery for ovarian cancer.Methods134 patients with ovarian cancer (FIGO I-IV) were included. 47 patients were prospectively studied after implementation of a mandatory ERAS protocol (ERAS group) and compared to 87 patients that were treated before implementation (pre-ERAS group). Primary endpoints of this study were the effects of the ERAS protocol on postoperative complications and length of stay in hospital.ResultsPreoperative and surgical data were comparable in both groups. Only the POSSUM score was higher in the ERAS group (11.8% vs. 9.3%, p < 0.001), indicating a higher surgical risk in the ERAS group. Total number of postoperative complications (ERAS: 29.8% vs. pre-ERAS: 52.8%, p = 0.011), and length of hospital stay (ERAS: 11 (6–23) vs pre-ERAS: 13 (6–50) days; p < 0.001) differed significantly. A lower fraction of patients of the ERAS group (87.2%) needed postoperative admission to the ICU compared to the pre-ERAS group (97.7%), p = 0.022). Mortality within the ERAS group was 0% vs. 3.4% (p = 0.552) in the pre-ERAS group.ConclusionThe implementation of a mandatory ERAS protocol was associated with a lower rate of postoperative complications and a reduced length of stay in hospital. If ERAS has influence on long-term outcome needs to be further evaluated.

Postoperative Complications of Minimally Invasive Intramedullary Nail Fixation Versus Plate Fixation for Distal Fibular Fractures in Elderly Patients: A Retrospective Double Cohort Study in a Geriatric Trauma Unit in the Netherlands

Intramedullary fixation using a fibular nail is a minimally invasive alternative to conventional plate fixation that provides superior biomechanical strength and allows immediate full weightbearing postoperatively. The study aim was to compare the postoperative complications of minimally invasive intramedullary fibular nail fixation to plate fixation for Lauge-Hansen supination external rotation type 4 (Weber B) fractures in patients aged 65 years or older treated in a single geriatric trauma unit in the Netherlands. A retrospective cohort study was performed including patients aged 65 years or older with a Lauge-Hansen supination external rotation type 4 (Weber B) fracture treated with either intramedullary fibular fixation or plate fixation between January 2017 and January 2019. A total number of 58 patients were included with a mean age of 73.9 years (range 65-95). The intramedullary fixation-cohort (n=13) had a significantly higher mean age (82.5 vs 71.4 years, p=.002) and Charlson Co-morbidity Index (4.7 vs 3.6, p=.005) compared to the plate fixation-cohort (n=45). The total number of postoperative complications was lower after intramedullary fixation (n=2, 15%) compared to plate fixation (n=15, 33%), although this relative difference was not significant (p=.307). All 2 complications observed after intramedullary fixation were wound infections demanding no debridement or implant removal. No implant related complications, hospital-acquired complications or mortality were observed after intramedullary fixation. Despite the higher mean age and co-morbidity status of patients treated with minimally invasive intramedullary fibular nailing, the total number of postoperative complications was lower after intramedullary fixation compared to plate fixation. This technique might be a promising alternative in selected patients.

Is Hyperthermic Intrathoracic Chemotherapy (HITHOC) Safe and Efficacious in Masaoka-Koga Stage-IVA Thymoma? A Pilot Study.

This study was aimed at evaluating the safety and efficacy of hyperthermic intrathoracic chemotherapy in patients with Masaoka stage IVA thymoma. This is a retrospective comparative analysis between two groups of patients who were operated for Masaoka stage IVA thymoma. One group underwent complete parietal pleurectomy whereas other group received hyperthermic intrathoracic chemotherapy after complete pleurectomy. An analysis of all perioperative variables, complications and survival was carried out. A total of 13 patients had stage IVA disease during the study period. Initial 7 patients (March 2012-March 2015) underwent complete parietal pleurectomy, whereas next 6 patients (April 2015-December 2018) had undergone HITHOC after complete parietal pleurectomy. Both groups are comparable in terms of age, co-morbidities, tumor size and duration of symptoms. The duration of surgery and intra-operative blood loss, postoperative ICU stay, duration of ICD and total hospital stay was similar between two groups. The total number of post-operative complications was higher in HITHOC group (5 vs 2), however non-significant (p = 0.10). The median follow-up duration was 63months in no HITHOC group and 49.5months in HITHOC group. There was no peri-operative mortality. The overall survival (P = 0.06) and relapse-free survival (P = 0.36) were not significantly different in the both groups. Hyperthermic intrathoracic chemotherapy is a safe and feasible modality with no added morbidity or mortality. Multi-institutional prospective studies with large number of patients are required to accurately assess survival benefit.

Association of Malnutrition, as Defined by the PG-SGA, ESPEN 2015, and GLIM Criteria, With Complications in Esophageal Cancer Patients After Esophagectomy.

Background: There are several approaches that can be used for the pre-treatment identification of malnutrition in oncology populations including the Patient-Generated Subjective Global Assessment (PG-SGA), the 2015 consensus statement by the European Society for Clinical Nutrition and Metabolism (ESPEN 2015) and the Global Leadership Initiative on Malnutrition (GLIM).Aims: This study aimed to evaluate whether malnutrition, as defined by these three methods, can be used to predict complications in esophageal cancer (EC) patients after esophagectomy.Methods: We performed a single center, observational cohort study that included 360 EC patients undergoing esophagectomy from December 2014 to November 2019 at Daping Hospital in China. The prevalence of malnutrition in the study population was prospectively defined using the PG-SGA (≥9 defined malnutrition), and retrospectively defined using the ESPEN 2015 and the GLIM. The prevalence of malnutrition and association with postoperative complications were compared in parallel for the three methods.Results: The prevalence of malnutrition before surgery was 23.1% (83/360), 12.2% (44/360), and 33.3% (120/360) in the study population, as determined by the PG-SGA, the ESPEN 2015 and the GLIM, respectively. The PG-SGA and GLIM had higher diagnostic concordance (Kappa = 0.519, P < 0.001) compared to the ESPEN 2015 vs. GLIM (Kappa = 0.361, P < 0.001) and PG-SGA vs. ESPEN 2015 (Kappa = 0.297, P < 0.001). The overall incidence of postoperative complications for the study population was 58.1% (209/360). GLIM- and ESPEN 2015-defined malnutrition were both associated with the total number of postoperative complications in multivariable analyses. Moreover, GLIM-defined malnutrition exhibited the highest power to identify the incidence of complications among all independent predictors in a pooled analysis.Conclusion: Among the PG-SGA, the ESPEN 2015 and the GLIM, the GLIM framework defines the highest prevalence rate of malnutrition and appears to be the optimal method for predicting postoperative complications in EC patients undergoing esophagectomy. These results support the importance of preoperatively identifying malnutrition using appropriate assessment tools, because it can facilitate the selection of management strategies that will optimize the clinical outcomes of EC patients.

Does the Use of Intraoperative Angiography Reduce the Incidence of Postoperative Wound and Flap Complications in Complex Lower Extremity Oncologic Reconstruction?

Intraoperative laser angiography via indocyanine green (ICG) has become a valuable tool in objectively assessing tissue perfusion in reconstructive procedures. Studies have demonstrated the utility of ICG angiography (ICGA) for decreasing both mastectomy skin flap necrosis and wound healing complications in abdominal wall reconstruction. This tool has not been studied in lower extremity oncologic reconstruction. The objective of this study was to compare postoperative complications in lower extremity oncologic reconstruction managed with or without laser-assisted ICGA. A retrospective chart review was performed of patients undergoing complex lower extremity oncologic reconstruction at a single institution between 2000 and 2018. Patient information regarding demographics, comorbidities, operative procedures, and postoperative complications was analyzed. Sixty-one patients were identified in our study. As some patients underwent multiple reconstructive surgeries, a total of 76 reconstructive procedures were analyzed. Patients with plastic surgery reconstruction using ICGA (n = 36) were compared with those without, non-ICGA (n = 40). No significant differences in age, sex, smoking status, chemotherapy, or radiation history were identified between cohorts. The total number of postoperative complications did not statistically differ between cohorts. There was no statistically significant difference in the number of required reoperation because of a postoperative complication between the ICGA and non-ICGA groups (0.44 vs 0.4). The incidence of postoperative wound complications after complex lower extremity oncologic reconstruction remains high. The findings of our study suggest that clinical judgment of flap and soft tissue viability, as compared with ICGA, may lead to comparable operative outcomes and be more cost-effective. Long-term follow-up and prospective studies are needed to further investigate this trend.

Study on the level of daily living function and its influencing factors in elderly patients after hip fracture surgery

To analyze the short-term prognosis of elderly patients with hip fracture after operation, and to explore the main factors affecting the recovery of daily life function. From November 2015 to November 2016, 130 elderly patients with hip fracture were analyzed, including 43 males and 87 females, aged from 60 to 95 (77.54±8.49) years. The death, fall and complications were recorded 3 months after operation. The daily life function of the patients was followed up 3 months after operation with the functional recovery of daily life scale (FRS). T-test, analysis of variance and single factor linear regression analysis were used to analyze the general clinical data. The factors with P<0.05 were analyzed by multi factor linear regression method, and the influencing factors of postoperative ADL were obtained. Among 130 patients, 7 died (5.4%), 4 fell (3.1%), 103 (79.2%) had postoperative complications, and the FRS score of 123 patients was 65.92±22.79. The results showed that gender, age, fracture site, pre fracture Basel rating, frailty index, postoperative hospital stay and total number of postoperative complications had significant differences in the recovery of daily life function (P<0.05);multiple linear regression analysis showed that pre fracture Basel rating (t=-2.727, P=0.007), frailty index (t=-2.573, P=0.011) and postoperative hospital stay had significant differences. The days of hospital stay (t=-3.391, P=0.001) and the total number of postoperative complications (t=-3.281, P=0.001) were the independent risk factors for postoperative ADL in elderly patients with hip fracture (R2=0.411). The short term rehabilitation level of elderly patients with hip fracture after operation is poor. Basel rating before fracture, frailty index, postoperative hospital stay and total number of postoperative complications may be related risk factors affecting the recovery of daily life function of patients after operation.

Prehabilitation With High Intensity Inverval Training Before Major Abdominal Surgery

PURPOSE: Improving cardiopulmonary reserve, or peak oxygen consumption (VO2peak) measured during cardiopulmonary exercise testing (CPET), may reduce complications after surgery. This feasibility study determined the effectiveness of a supervised, preoperative High Intensity Interval Training (HIIT) program in increasing VO2peak by 2ml/kg/min. Clinical outcomes were documented to determine the endpoint most sensitive to improved fitness. METHODS: In this prospective study, participants aged 50-85 undergoing major abdominal surgery were randomised to standard care or 14 sessions of HIIT over 4-6 weeks. HIIT sessions involved approximately thirty minutes of stationary cycling (5 warm-up, 20 interval training, 5 cool-down). Interval training alternated 1 minute of high and low intensity pedalling, with the goal of reaching 90% maximum heart rate during the session. Clinical outcomes included complications, postoperative morbidity survey, length of stay, and Short Form-36 quality of life questionnaire (SF-36). RESULTS: Of 63 participants, 46 completed both CPETs and 51 completed clinical follow-up. On per protocol analysis, mean VO2peak increased 14%, from 20.3-23.2ml/kg/min in the exercise group and 0.7%, from 21.8-22.0 ml/kg/min in the control group. Change in VO2peak was 2.87 vs. 0.14 ml/kg/min (p<.001). Exercisers increased peak work rate by 25 watts. Although there were no significant differences in the clinical outcomes, those most responsive to improved fitness with exercise were: the total number of postoperative complications (0.64 in exercisers vs. 1.16 in controls per patient, p=.07) and the physical component score of the SF-36 (p=.07), with the greatest difference six weeks after surgery indicating a quicker postoperative recovery. CONCLUSION: There was a significant improvement in VO2peak and peak work rate with preoperative HIIT. We also noted a trend towards fewer postoperative complications and a more rapid recovery after surgery. Preoperative HIIT results in a clinically important improvement in cardiopulmonary reserve for patients undergoing abdominal surgery.

Perioperative complications of abdominal surgery in smokers

PurposeThis study examined the association between smoking and perioperative complications of laparoscopic abdominal surgery and whether these complications were reduced with ≥ 4 weeks of preoperative smoking cessation.MethodsA total of 555 patients who underwent gastric and colorectal cancer surgeries under general anesthesia were divided into the following groups retrospectively: 290 individuals without smoking history (NS group), 144 previous smokers (stopped smoking more than 8 weeks before surgery, PS group), and 121 current smokers (CS group) divided to two groups according to preoperative smoking cessation for < 4 (CS1, n = 76) and 4–8 weeks (CS2, n = 45).ResultsWhen compared with the NS group, postoperative hospitalization duration was significantly longer in the CS1 group (p < 0.01), whereas differences between the CS2 or PS groups and NS group were not significant. The total number of postoperative complications was higher in all groups of smoking than in NS group, independent on preoperative smoking cessation; however, suture failure was significantly more frequent only in CS1 group. Although pack-years did not significantly affect complication rates in smokers, duration of smoking cessation time in PS group was a negative predictor of postoperative complications.ConclusionProviding more than 4 weeks of smoking cessation before gastrointestinal surgery can reduce the duration of hospitalization and rate of suture failure.

DIVERTICULAR DISEASE: FROM TRADITION TO INNOVATION

This article presents current data from the world medical literature and a five-year study of surgical clinic on the effect of perioperative intestinal decontamination in patients with acute complicated diverticulitis on the frequency of postoperative complications after elective resection of the sigmoid colon and the formation of primary colorectal anastomosis. The possibility of selective perioperative intestinal decontamination in patients with acute sigmoid diverticulitis complicated by covered perforation, the number of postoperative surgical and general complications was observed. The used scheme of topical antibacterial sanitation, along with orthograde intestinal cleansing with osmolar solutions, significantly reduced the frequency of insufficiency of colectal anastomoses, surgical (abdominal) and the total number of postoperative complications.

КЛИНИЧЕСКАЯ И ЭКОНОМИЧЕСКАЯ ЭФФЕКТИВНОСТЬ ПРИМЕНЕНИЯ ПРЕПАРАТА СМЕСИ ЭФИРОВ ТЕСТОСТЕРОНА ПРИ ХИРУРГИЧЕСКОМ ЛЕЧЕНИИ МУЖЧИН С ОСТРЫМИ ИНФЕКЦИОННЫМИ ДЕСТРУКЦИЯМИ ЛЁГКИХ

Based on the results of examination and treatment of 80 men with acute infectious pulmonary destructions requiring surgery it was found that the use of the testosterone esters drug mixture lead to an increase in its concentration in serum (pWilcoxon=0.000001) and eliminated cases of its deficiency (p(Fisher)=0.0). It was also established that the use of the above mixture helped reduce the need in parenteral nutrition (χ2=6.36; p=0.012) and transfusions of albumin solution (χ2=5.98; p=0.015), maintain body weight (p(Wilcoxon)=0.38), decrease the total number of postoperative complications by 2 times (U=81; p(Mann-Whitney)=0,011) and cases of postoperative morbidity from 79% to 53% (χ2=5,85; p=0,016), as well as reduce the material costs for the treatment of patients.

Pharmacist involvement to improve patient outcomes in lower gastrointestinal surgery: a prospective before and after study.

Background Enhanced recovery pathways were first introduced in the UK in 2002 (Enhanced Recovery Partnership Programme in Delivering enhanced recovery-helping patients to get better sooner after surgery. Department of Health, London, 2010). The aims of such pathways are to reduce patient length of stay whilst still providing high quality of care. Objectives To evaluate the impact of pharmacist involvement in enhanced recovery pathways. Setting A large 1200 bed tertiary hospital in the North of England. Methods The pre-post study included all patients admitted for major colorectal surgery during the period 2013-2016. Baseline data were collected on all patients seen pre-operatively in a nurse-led pre-admission clinic. The intervention was introduced where a dedicated surgical pharmacist pre-operatively reviewed patients from the time they were listed for surgery until discharge with a focus on medicines optimisation. Main outcome measure The primary outcome measures were length of stay along with the type and number of post-operative complications. Results 100 patients were included in this study, with 50 patients in the baseline group and 50 patients in the intervention group. There was a significant reduction in the median length of stay (baseline group-10.5days; intervention group-7.5days; P < 0.001). The total number of complications was also less in the intervention group (baseline group-125; intervention group-75; P > 0.05) as was the number of patients whom had no complications (P > 0.05). Conclusions Active pharmacist involvement in enhanced recovery protocols is associated with a significantly reduced median length of stay as well as an overall reduction in the total number of post-operative complications.

Rationale and Study Design for an Individualized Perioperative Open Lung Ventilatory Strategy in Patients on One-Lung Ventilation (iPROVE-OLV)

The aim of this clinical trial is to examine whether it is possible to reduce postoperative complications using an individualized perioperative ventilatory strategy versus using a standard lung-protective ventilation strategy in patients scheduled for thoracic surgery requiring one-lung ventilation. International, multicenter, prospective, randomized controlled clinical trial. A network of university hospitals. The study comprises 1,380 patients scheduled for thoracic surgery. The individualized group will receive intraoperative recruitment maneuvers followed by individualized positive end-expiratory pressure (open lung approach) during the intraoperative period plus postoperative ventilatory support with high-flow nasal cannula, whereas the control group will be managed with conventional lung-protective ventilation. Individual and total number of postoperative complications, including atelectasis, pneumothorax, pleural effusion, pneumonia, acute lung injury; unplanned readmission and reintubation; length of stay and death in the critical care unit and in the hospital will be analyzed for both groups. The authors hypothesize that the intraoperative application of an open lung approach followed by an individual indication of high-flow nasal cannula in the postoperative period will reduce pulmonary complications and length of hospital stay in high-risk surgical patients.

INFLUENCE OF THE ANESTHESIA METHOD ON THE OUTCOMES OF CARDIAC SURGERY OF DIFFERENT COMPLEXITY IN CHILDREN

The Aristotle score: a complexity-adjusted method to evaluate surgical results. For an assessment of dynamics of quality of the provided cardio-surgical help, comparison of a perioperative case rate and a mortality depending on the degree of surgical risk at cardiac interventions the Aristotle score is used. Thoracic epidural anesthesia (TEA) in comparison with high-opioids intravenous anesthesia (IVA) contributes to hemodynamics stability and early activation of patients. Objective: To analyze a current of the perioperative period at cardiac interventions in children with various categories of complexity of surgical intervention on «Aristotle score» depending on a type of anesthesia. Materials and methods. The 139 children with congenital heart diseases (CHD) underwent surgical correction. Patients were treated in Federal State Budgetary Institution of the Russian Ministry of Health (Penza), and «Almazov National medical research Centre» from 2008 to 2017 yrs. Patients (139 people, the mean age M (SD) of 7.6 (5.6) months of life) were divided into groups according to the categories of operational complexity presented in the Aristotle score. The group 1 consisted of 85 (61.2%) patients underwent interventions of second category of complexity, the group 2 consisted of 49 (39.8%) patients underwent interventions of 3 and 4 categories of complexity. Results. In cardiosurgical operations of the 2nd category of the Aristotle scale complexity a significant positive effect of TEA on the perioperative period was revealed in the form of a decrease in the severity of intraoperative heart failure and the level of glycaemia, the total number of postoperative complications and the time of patients’ staying on mechanical ventilation, as well as the duration of ICU stay and the decrease thrombocytopenia severity and frequency. In operations of grade 3 and 4, in which the duration of extracorporeal circulation was greater, the use of TEA did not have a significant positive effect on the incidence of postoperative complications, but after epidural anesthesia the mean duration of the patients’ stay on the mechanical ventilation and in the ICU was also significantly less. Apparently, the result is a consequence of a lesser severity of heart failure and early activation of patients by excluding the use of opioids, which have a depressing effect on the central nervous system, cardiac, respiratory and other systems. It can also be assumed that the administration of local anesthetics within 24 hours after the operation maintained sympatholytic and antiarrhythmic effects, and also prevented the complications development as a result of effective analgesia. Sufficiently convincing evidence of high antinociceptive activity of TEA is the possibility of safe extubation of patients in both the 2-d and 3-d categories of surgical complexity demonstrated in our study already in the operating room. Conclusion. Use of high TEA as a component of the combined anesthesia at surgical correction of CHD in young children has positive impact on a current of the perioperative period in the form of decrease in severity of heart and respiratory failure, duration of respiratory support, early activation and reduction of ICU stay.
