Background Surgery remains the mainstay of gastric cancer treatment. It is, however, associated with a relatively high risk of perioperative complications. The use of laparoscopy and the Enhanced Recovery After Surgery (ERAS) protocol allows clinicians to limit surgically induced trauma, thus improving recovery and reducing the number of complications. The aim of the study is to present clinical outcomes of patients with gastric cancer undergoing laparoscopic gastrectomy combined with the ERAS protocol. Material/Methods Fifty-three (21 female/32 male) patients who underwent elective laparoscopic total gastrectomy due to cancer were prospectively analyzed. Demographic and surgical parameters were assessed, as well as the compliance with ERAS protocol elements, length of hospital stay, number of complications, and readmissions. Results Mean operative time was 296.4±98.9 min, and mean blood loss was 293.3±213.8 mL. In 3 (5.7%) cases, conversion was required. Median length of hospital stay was 5 days. Compliance with ERAS protocol was 79.6±14.5%. Thirty (56.6%) patients tolerated an early oral diet well within 24 h postoperatively; in 48 (90.6%) patients, mobilization in the first 24 hours was successful. In 17 (32.1%) patients, postoperative complications occurred, with 7 of them (13.2%) being serious (Clavien-Dindo 3-5). The 30-day readmission rate was 9.4%. Conclusions The combination of laparoscopy and the ERAS protocol in patients with gastric cancer is feasible and allows achieving good clinical outcomes.

UNLABELLED Age is one of the principal risk factors for colorectal adenocarcinoma. To date, older patients were believed to achieve worse treatment results in comparison with younger patients due to reduced vital capacity. However, papers have emerged in recent years which confirm that the combination of laparoscopy and postoperative care based on the ERAS protocol improves treatment results and may be particularly beneficial also for elderly patients. The aim of the study was to compare the outcomes of laparoscopic surgery for colorectal cancer in combination with the ERAS protocol in patients aged above 80 and below 55. MATERIAL AND METHODS The analysis included patients aged above 80 and below 55 undergoing elective laparoscopic colorectal resection for cancer at the 2nd Department of General Surgery of the Jagiellonian University. They were divided into two groups according to their age: ≥ 80 years of age (group1) and ≤ 55 years of age (group 2). Both groups were compared with regard to the outcome of surgery: length hospital stay, complications, hospital readmissions, degree of compliance with the ERAS protocol, and recovery parameters (tolerance of oral nutrition, mobilisation, need for opioids, restored gastrointestinal function). RESULTS Group 1 comprised 34 patients and group 2, 43 patients. No differences were found between both groups in terms of gender, BMI, tumour progression or surgical parameters. Older patients typically had higher ASA scores. No statistically significant differences were found with regard to the length hospital stay following surgery (5.4 vs 7 days, p=0.446481), the occurrence of complications (23.5% vs 37.2%, p=0.14579) or hospital readmissions (2.9% vs 2.4%). The degree of compliance with the ERAS protocol in group 1 and 2 was 85.2% and 83.0%, respectively (p=0.482558). Additionally, recovery parameters such as tolerance of oral nutrition (82.4% vs 72.1%, p=0.28628) and mobilisation (94.1% vs 83.7%, p=0.14510) within 24 hours of surgery did not differ among the groups. However, a smaller proportion of older patients required opioids in comparison with younger patients (26.5% vs 55.8%, p=0.00891). CONCLUSIONS Similar levels of compliance with the ERAS protocol may be achieved among patients aged ≥ 80 and younger patients. When laparoscopy is combined with the ERAS protocol, age does not seem to be a significant factor that could account for worse outcomes. Therefore, older patients should not be excluded from perioperative care based on ERAS principles.

Introduction The goal of modern medical treatment is to provide high quality medical care in a cost-effective environment. Aim To assess the cost-effectiveness of laparoscopic colorectal surgery combined with the enhanced recovery after surgery protocol (ERP) in Poland. Material and methods We designed a single-centre, case-matched study. Economic and clinical data were collected in 3 groups of patients (33 patients in each group): group 1 – patients undergoing laparoscopy with ERP; group 2 – laparoscopy without ERP; group 3 – open resection without ERP. An independent administrative officer, not involved in the treatment process, matched patients for age, sex and type of resection. Primary outcome was cost analysis. It was carried out incorporating institutional costs: hospital bed stay, anaesthesia, surgical procedure and equipment, drugs and complications. Secondary outcomes were length of stay (LOS), readmission and complication rate. Results Cost of laparoscopic procedure alone was significantly more expensive than open resection. However, implementation of the ERAS protocol reduced additional costs. Total cost per patient in group 1 was significantly lower than in groups 2 and 3 (EUR 1826 vs. EUR 2355.3 vs. EUR 2459.5, p < 0.0001). Median LOS was 3, 6 and 9 days in groups 1, 2 and 3 respectively (p < 0.001). Postoperative complications were noted in 5 (15.2%), 6 (18.2%) and 13 (39.4%) patients in groups 1, 2, 3 respectively (p = 0.0435). Conclusions In a low medical care expenditure country, minimally invasive surgery combined with ERP can be a safe and a cost-effective alternative to open surgery with traditional perioperative care.

Introduction Modern perioperative care principles in elective colorectal surgery have already been established by international surgical authorities. Nevertheless, barriers to the introduction of routine evidence-based clinical care and changing dogmas still exist. One of the factors is the surgeon. Aim To assess perioperative care trends in elective colorectal surgery among general surgery consultants in surgical departments in Malopolska Voivodeship, Poland. Material and methods An anonymous standardized 20-question questionnaire was developed based on ERAS principles and sent out to Malopolska Voivodeship general surgery departments. Answers of general surgery consultants showed the level of acceptance of elements of perioperative care. Results The overall response rate was 66%. Several elements (antibiotic and antithrombotic prophylaxis, postoperative oxygen therapy, no nasogastric tubes) had quite a high acceptance rate. On the other hand, most crucial surgical perioperative elements (lack of mechanical bowel preparation, preoperative oral carbohydrate loading, use of laparoscopy and lack of drains, early fluid and oral diet intake, early mobilization) were not followed according to evidence-based ERAS protocol recommendations. Surgeons were not willing to change their practice, but were supportive of changes in anesthesiologist-dependent elements of perioperative care, such as restrictive fluid therapy, use of transversus abdominis plane blocks, etc. Conclusions Many elements of perioperative care in elective colorectal surgery in Malopolska Voivodeship are still dictated by dogma and are not evidence-based. The level of acceptance of many important ERAS protocol elements is low. Surgeons are ready to accept only changes that do not interfere with their practice.

AIM OF THE STUDY The aim of this study was to evaluate the influence of laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric by-pass on risk factors of cardiovascular diseases. MATERIAL AND METHODS We analyzed prospectively collected data of patients operated for morbid obesity who were qualified for laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux-en-Y gastric by-pass (LRYGB). Risk factors for wyłączecardiovascular diseases were assessed with the SCORE scale and both full and hard Framingham cardiovascular risk scores (FCRs). The data were collected on admission and one year after the procedures. We enrolled 264 patients (119 females, 116 males, 40.2±9.9 years old), of whom 117 underwent LRYGB and 118 LSG, respectively. RESULTS Preoperatively, 12% of patients were in the high-risk category of the SCORE scale, 65% were in the moderate risk category, and 24% were in the low-risk category. The median score of the SCORE scale was 1 (1-2). Lipid-based full FCR was 34.5% (24%-68%) and the hard FCR was 17.5% (10%-52%), while the respective BMI-based FCRs were 59% (31%-84%) and 37% (15%-67%). One year after the procedures, the mean %EBMIL (62.88%±20.02%) and %EWL (53.18%±15.87) were comparable between both procedures. Hypertension treatment was not necessary in 33 patients after LSG and in 55 after LRYGB. Diabetes mellitus remitted in 9 and 29 patients, respectively. Both procedures significantly reduced high and moderate risk prevalence in the SCORE scale in favor of the low risk category. Surgical interventions resulted in significant reductions of FCRs 1 year after surgery ( p<0.001). CONCLUSIONS Both LSG and LRYGB lead to a significant and comparable body mass reduction. Both procedures significantly decrease of the risk of cardiovascular diseases, based on SCORE and Framingham scales.

UNLABELLED Postoperative insulin resistance, used as a marker of stress response, is clearly an adverse event. It may induce postoperative hyperglycemia, which according to some authors can increase the risk of postoperative complications. One of the elements of modern perioperative care is preoperative administration of oral carbohydrate loading (CHO-loading), which shortens preoperative fasting and reduces insulin resistance. The aim of the study is to establish the influence of CHO-loading on the level of insulin resistance and cortisol in patients undergoing elective laparoscopic cholecystectomy. MATERIAL AND METHODS Patients were randomly allocated to one of 2 groups. The intervention group included 20 patients who received CHO-loading (400 ml Nutricia pre-op®) 2 hours prior surgery. The control group received a placebo (clear water). In every patient blood samples were taken 2 hours prior to surgery, immediately after surgery, and on the 1st postoperative day. Levels and changes in glucose, cortisol and insulin resistance were analyzed in both groups. RESULTS Although there were differences in the levels of cortisol, insulin, and insulin resistance, no statistically significant differences were observed between groups in every measurement. The length of stay and postoperative complications were comparable in both groups. CONCLUSIONS We believe that CHO-loading is not clinically justified in case of laparoscopic cholecystectomy. No effect on the levels of glucose, insulin resistance and cortisol was observed. Even though such procedure is safe, in our opinion there is no clinical benefit from CHO-loading prior to laparoscopic cholecystectomy.

Introduction Thanks to laparoscopy and enhanced recovery protocols (ERAS) it is possible to shorten hospitalization. Therefore, it seems reasonable to search for new early markers of infectious complications in order to select patients who are prone to development of complications. Aim To assess the usefulness of serum levels of C-reactive protein, interleukin-6 and procalcitonin as early indicators of infectious complications in patients after laparoscopic colorectal surgery with ERAS. Material and methods The prospective analysis included consecutive patients who underwent laparoscopic colorectal cancer resection. The following parameters were included in the analysis: C-reactive protein (CRP), interleukin 6 (IL-6) and procalcitonin measured on postoperative days (PODs) 1, 2, 3. Patients were divided into two groups: uncomplicated (group 1) and complicated (group 2). The difference in levels of the markers and the dynamics of changes observed in both groups were analyzed. Results Group 1 comprised 34 patients, and group 2 consisted of 17 patients. A significant increase of both absolute values and delta increments on all postoperative days was noted. ROC curve analysis showed that the best cut-off values indicating an infectious process were: CRP 129 mg/l on POD3 (92% sensitivity/80% specificity), IL-6 of 78 pg/ml on POD2 (91% sensitivity/97% specificity) and PCT 0.24 ng/ml on POD3 (93% sensitivity/68% specificity). Conclusions Our study showed that regular measurement of all analyzed markers in the early postoperative days may be beneficial in the detection of postoperative infectious complications. Further studies are needed to fully assess the role of routine biochemical measurements in the postoperative period after laparoscopic surgery with the ERAS protocol.

Most of the studies concerning enhanced recovery after surgery (ERAS) protocols in colorectal surgery include heterogeneous groups of patients undergoing open or laparoscopic surgery, both due to colonic and rectal cancer, thus creating a potential bias. The data investigating the differences between patients operated for either colonic or rectal cancer are sparse. The aim of the study was to compare short-term outcomes of laparoscopic surgery for colonic and rectal cancer with ERAS protocol. The analysis included consecutive prospectively registered patients operated for a colorectal cancer between January 2012 and September 2015. Patients were divided into two groups (colon vs. rectum). The measured outcomes were: length of stay (LOS), complication rate, readmission rate, compliance with ERAS protocol elements and recovery parameters (tolerance of early oral diet, mobilization and time to first flatus). Group 1 (colon) consisted of 150 patients and Group 2 (rectum) of 82 patients. Patients in Group 1 (150 patients) were discharged home earlier than in Group 2 (82 patients)—median LOS 4 versus 5 days, respectively. There was no statistical difference in complication rate (27.3 vs. 36.6 %) and readmissions (7.3 vs. 6.1 %). Compliance with the protocol was 86.9 and 82.6 %, respectively. However, in Group 1, the following procedures were used less frequently: bowel preparation (24 vs. 78.3 %) and postoperative drainage (23.3 vs. 71.0 %). There were no differences in recovery parameters between the groups. Univariate logistic regression showed that the type of surgery, drainage and stoma creation significantly prolonged LOS. In a multivariate logistic regression model, only a bowel preparation and drainage were shown to be significant. Although functional recovery and high compliance with ERAS protocol are possible irrespective of the type of surgery, laparoscopic rectal resections are associated with a longer LOS.
