Summary Background 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. Methods This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov , NCT03471494 . Findings Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70–8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39–8·80) and upper-middle-income countries (2·06, 1·11–3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26–11·59) and upper-middle-income countries (3·89, 2·08–7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. Interpretation Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

Purpose: Venous thromboembolism (VTE) after colorectal surgery is a well-documented complication, resulting in a general recommendation of extended post discharge prophylaxis. Rivaroxaban, a factor Xa inhibitor, is a daily tablet approved for treatment of VTE and prophylaxis after orthopedic surgery. The purpose of this study is to evaluate the safety of rivaroxaban for extended prophylaxis after major abdominal and pelvic surgery. Methods: This is a retrospective review of patients undergoing major colorectal surgery at a regional hospital in Kiev, Ukraine. Patients received peri-operative VTE prophylaxis with subcutaneous heparin and then transitioned to rivaroxaban for a total of 30 days. Occurrences of major or minor bleeding, blood transfusion, and a need for re-intervention were noted. Phone surveys were administered on post-operative day 30 to assess compliance and satisfaction with the regimen. Results A total of 51 patients were included in the study with an average age of 62.4 years old. Seventy-one percent of the cases were abdominal cases, 29% were pelvic cases and 59% were done laparoscopically. There was one episode of major intra-abdominal bleeding requiring return to the operating room. There were 2 minor bleeding episodes not requiring intervention. There were no VTE events in the group. The phone survey response rate was 100%. All but one patient reported completing the full course of rivaroxaban. Patients reported that oral prophylaxis was easy to adhere to and preferable compared to injections. Conclusion Implementation of extended prophylaxis with rivaroxaban is easy, safe and does not increase rates of post-operative bleeding.
IntroductionThe method of a bipolar high-frequency welding (HFEW) of soft living tissues of animals and humans has been used in various areas of surgery. However, it has not been utilized in endoscopic gastrointestinal procedures yet. HFEW has strong potential to be used in gastrointestinal endoscopic procedures due to the competitive cost of generator devices and due to its proven ability to coagulate vessels of wide diameter as compared to standard electrocautery devices.AimTo investigate the effectiveness of the endoscopic haemostasis using HFEW generator device – 300 PATONMED – in a porcine model of arterial gastrointestinal bleeding.Material and methodsA porcine model of arterial gastrointestinal bleeding was created. A 300 PATONMED set to the “welding” regime and a flexible 7 Fr bipolar coagulation probe with two electrodes on the tip fashioned spirally attached to convey energy were tested. Once bleeding from the artery had been initiated, the bipolar probe was applied to coagulate the bleeding site. Animals were observed for clinical evidence of recurrent bleeding and subsequently were euthanised for histological examination.ResultsA total of 10 experiments were successfully completed. An optimal haemostatic effect was achieved with durations of cautery of five to eight seconds in all animals. Continuous observation after haemostasis revealed no evidence of re-bleeding. No systemic side-effects of the technique were observed. Histological examination has shown that the peripheral thermal injury area that surrounded the coagulation zone did not spread beyond the mucosal layer in depth and 2 mm in width.ConclusionsThis animal study provided evidence for the safety of an HFEW in the treatment of gastrointestinal bleeding. The advantages of this technology are smokeless operative area, no tissue overheating, minimal necrosis and damage to surrounding gastric tissue, and the fact that the area of HFEW is confined to the area of the electrodes.
<b>Introduction:</b> In today’s technological climate, science and medicine have entered a new era. At the level of technological progress, we have identified millennia of “new” problems and diseases. If earlier diseases had a certain individuality then, in the third millennium, we face compliance and synergistic influence of diseases. Obesity is a problem of the third millennium. It is known that obesity is the main factor in the development of various chronic diseases [1–3]. With excess weight and obesity, bile is oversaturated with cholesterol, resulting in an increase of its lipogenicity index. As a result, frequency of gallstone disease increases; findings from this study document an increase of disease frequency as high as 50% to 60% [4]. In 20% of patients, housing concerns are combined with obesity [5]. Thus, obesity is one of the factors in the development of cholelithiasis and cholecystitis [6]. The presence of acute cholecystitis represents the most difficult situation for patients with gallstones. When obesity is also present, the patient’s risk of surgical complications increases due to altered homeostasis and reduced reserve capacity [7]. A retrospective study of this issue [8] posed a number of questions about the possibility of influencing the course of disease in the preoperative period as well as the improvement and impact of surgical technicalities in patients with acute cholecystitis and obesity. Addressing these and additional questions is the main goal of this study. <br><b>Aim: </b>The aim of the study was to study and select the optimal method of surgery in patients with acute cholecystitis and obesity. <br><b>Materials and methods:</b> In our study, a prospective analysis was used. We analyzed 67 cases with diagnosis of acute cholecystitis and obesity; all were treated at Kyiv Regional Clinical Hospital in the period from September 2018 to March 2020. Patients with acute cholecystitis and obesity received either traditional or modified laparoscopic cholecystectomy. <br><b>Results:</b> Retrospective analysis indicates traditional laparoscopic cholecystectomy is technically difficult and costly in patients with acute cholecystitis and obesity. A modified laparoscopic cholecystectomy has been proposed to improve and enhance surgery in patients with acute cholecystitis and obesity. Surgical duration was shortened by 9.01 ± 0.41 minutes (p = 0.001; αα= 0.05) when a modified laparoscopic cholecystectomy was performed. <br><b>Conclusions:</b> Performing a modified laparoscopic cholecystectomy reduced the duration of surgery by 9.01 ± 0.41 minutes (p = 0.001; α = 0.05), prevents development of metabolic acidosis pH 7.39 ± 0.03 vs 7.30 ± 0.005 = 0.001; αα= 0.05, pCO2 5.05 ± 0.36 vs 6.03 ± 0.38 (p = 0.02; αα= 0.05), reducing the risk of hypercoagulation. Modified laparoscopic cholecystectomy (LHE) is effective in II and III degrees of obesity (p = 0.001; α = 0.05).
