SummaryBackgroundSurgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world.MethodsThis international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231.FindingsBetween Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p<0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p<0·001).InterpretationCountries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication.FundingDFID-MRC-Wellcome Trust Joint Global Health Trial Development Grant,...
al. Should there be a specific length of the colon-rectum segment to be resected for an adequate number of lymph nodes in cases of colorectal cancers? A retrospective multi-center study.
BACKGROUND: Clinical scoring systems have been used to reduce negative appendectomy rate for several decades. However, the use of these systems has been questioned due to differences in their diagnostic accuracies. The aim of this prospective study was to develop a new clinical scoring system using a combination of all previously described variables for the diagnosis of acute appendicitis (AA). METHODS:Consecutive patients who underwent emergency appendectomy for AA between December 2016 and April 2017 were prospectively included in the study. During admission, a prepared questionnaire including variables obtained from the previously used clinical scoring systems was administered. Histopathological analysis was regarded as the main outcome. Patients with no histopathological evidence of AA were defined as negative appendectomy. All variables were analyzed separately to assess their association with AA. A receiver operating characteristic curve with area under curve analysis was performed to obtain the cut-off values for numerical variables. RESULTS:There were 200 patients with a mean age of 30.8±12.8 years with a negative appendectomy rate of 5.5%. There was no significant association between the variables and the detection of histologically proven AA except increased white blood cell count >11.05/mm 3 and proportion of the polymorphonuclear leukocytes >71.2% (p=0.003 and p=0.015, respectively). CONCLUSION:The present study shows that the development and/or use of scoring systems does not significantly improve the diagnostic accuracy of AA.
Objective: Choledochal cyst is a congenital disease in which surgical treatment is preliminary because of the potential for malignancy. In recent years, increase in technological developments and laparoscopic experience have popularised the use of laparoscopy in adult choledochal cyst surgery. This study aimed to present the results of eight adult patients undergoing laparoscopic choledochal excision surgery. Material and Methods:Patients who underwent laparoscopic choledochal cyst excision and hepatico-jejunostomy anastomoses between the years 2013 and 2018 were evaluated retrospectively. Demographic characteristics, preoperative and postoperative findings, pathological results and final condition of the patients were examined. Results:Of the eight patients, three were males and five were females. Median age was 41.5 years (22-49). One of the patients had Type IVa and the rest had Type I choledochal cysts. Laparoscopic choledochal cyst excision, cholecystectomy, and hepatico-jejunostomy anastomoses were performed on all of the patients. One patient was converted to open surgery. Three patients had postoperative biliary leakage. Duration of the operations was determined as median 330 (240-480) minutes and blood loss was 50 (10-100) mL. Hospitalization of the patients was median 6 (4-23) days and follow-up time was median 20 (2-65) months. In the late period, cholangitis occured in a patient who was treated with medical therapy and there was no mortality in the follow-up period. Conclusion:We suggest that laparoscopic choledochal cyst excision in adults may be an alternative to open surgery due to the satisfactory results in the late period in spite of early problems like self-limiting bile leakage.
Background: It is a challenging question, especially in bariatric surgery (BS), whether antibiotic prophylaxis is necessary in all cases; considering the serious consequences of surgical site infection (SSI) on the one hand and irrational use of antibiotics on the other. The aim of this study was to determine the need/rationale for antibiotic prophylaxis in patients undergoing laparoscopic bariatric surgery, especially low-risk patients. Methods: This retrospective analysis involved 313 morbidly obese patients (body Mass Index [BMI] ‡40) who underwent laparoscopic BS at three medical centers between September 2018 and June 2019. During the trial, no inducement was given to use antibiotics, and the centers had chosen whether to use prophylaxis. The U.S. Centers for Disease Control and Prevention (CDC)-2016 criteria were used for the diagnosis of SSI. Results: Antibiotic prophylaxis was given to 181 patients, and the SSI rate in the entire series was 4.5% (14/ 313). There was no significant difference in SSI between the group who received antibiotics and that who did not (2.8% versus 6.8%, respectively; p = 0.09). Post-operative intra-abdominal complications were the main independent determinant for SSIs (p < 0.001). Antibiotic prophylaxis did not have any significant effect on the rate of SSI caused by these complications (2.2% versus 3.8%, respectively; p = 0.50). The second independent factor was the rate of SSI in patients with super-obesity (BMI ‡60), particularly incisional SSIs (p < 0.001). Antibiotic prophylaxis did not produce any significant decrease in the rate of SSI in patients with a BMI < 60 (2.8% versus 5.5%, respectively; p = 0.24). When these two independent factors were excluded, there were no patients with SSI in the no-antibiotics group, and only one in the antibiotic prophylaxis group (0.5%) (p = 1.00). Conclusions: Routine antibiotic prophylaxis should be questioned in laparoscopic BS. Prophylaxis may reduce incisional SSI in patients with a BMI of ‡60. In other cases, antibiotic prophylaxis does not provide a decrease in SSI.
