ABSTRACT

The main goals of the Enhanced recovery after surgery (ERAS) protocol are focused on shortening the length of hospital stay (LOS), expediting convalescence, and reducing morbidity. A balanced perioperative fluid therapy is among the significant interventions incorporated by the ERAS protocol. The article contains extensive discussion surrounding the impact of this individual intervention on short-term outcomes. The aim of this study was to assess the impact of perioperative fluid therapy on short-term outcomes in patients after laparoscopic colorectal cancer surgery. The analysis included consecutive patients, who had undergone laparoscopic colorectal cancer operations between 2013 and 2020. Patients were divided into two groups: restricted (≤ 2500 ml) or excessive (> 2500 ml) perioperative fluid therapy. A standardized ERAS protocol was implemented in all patients. The study outcomes included recovery parameters and the morbidity rate, LOS and 30 days readmission rate. There were 361 and 80 patients in groups 1 and 2, respectively. There were no statistically significant differences between the groups in terms of demographic parameters and factors related to the surgical procedure. Logistic regression showed that restricted fluid therapy as a single intervention was associated with improvement in tolerance of diet on 1st postoperative day (OR 2.18, 95% CI 1.31-3.62, p = 0.003), accelerated mobilization on 1st postoperative day (OR 2.43, 95% CI 1.29-4.61, p = 0.006), lower risk of postoperative morbidity (OR 0.58, 95%CI 0.36-0.98, p = 0.046), shorter LOS (OR 0.49, 95% CI 0.29-0.81, p = 0.005) and reduced readmission rate (OR 0.48, 95% CI 0.23-0.98, p = 0.045). A balanced perioperative fluid therapy on the day of surgery may be associated with faster convalescence, lower morbidity rate, shorter LOS and lower 30 days readmission rate.

ABSTRACT

OBJECTIVE: Comprehensive analysis and comparison of HRQoL following different bariatric interventions through systematic review with network meta-analysis. BACKGROUND: Different types of bariatric surgeries have been developed throughout the years. Apart from weight loss and comorbidities remission, improvement of health-related quality of life (HRQoL) is an important outcome of metabolic surgery. METHODS: MEDLINE, EMBASE, and Scopus databases have been searched up to April 2020. Inclusion criteria to the analysis were (1) study with at least 2 arms comparing bariatric surgeries; (2) reporting of HRQoL with a validated tool; (3) follow-up period of 1, 2, 3, or 5 years. Network meta-analysis was conducted using Bayesian statistics. The primary outcome was HRQoL. RESULTS: Forty-seven studies were included in the analysis involving 26,629 patients and 11 different surgeries such as sleeve gastrectomy (LSG), gastric bypass (LRYGB), one anastomosis gastric bypass (OAGB), and other. At 1 year, there was significant difference in HRQoL in favor of LSG, LRYGB, and OAG compared with lifestyle intervention (SMD: 0.44; 95% CrI 0.2 to 0.68 for LSG, SMD: 0.56; 95% CrI 0.31 to 0.8 for LRYGB; and SMD: 0.43; 95% CrI 0.06 to 0.8 for OAGB). At 5 years, LSG, LRYGB, and OAGB showed better HRQoL compared to control (SMD: 0.92; 95% CrI 0.58 to 1.26, SMD: 1.27; 95% CrI 0.94 to 1.61, and SMD: 1.01; 95% CrI 0.63 to 1.4, respectively). CONCLUSIONS: LSG and LRYGB may lead to better HRQoL across most follow-up time points. Long-term analysis shows that bariatric intervention results in better HRQoL than non-surgical interventions.

ABSTRACT

INTRODUCTION: Bariatric surgery is an effective method of treatment for morbid obesity that is known to change nutritional habits. Proper nutrition has an impact on postoperative recovery and outcomes. Diet preferences depend on flavour and olfaction stimuli. Some studies show long-term changes in the sense of smell after bariatric surgery, but little research has addressed olfactory function shortly after surgery. Observations of olfactory changes that occur immediately after bariatric surgery may lead to improvements in postoperative care. AIM: The aim of this study is to investigate the impact of bariatric surgery on olfactory changes in the short postoperative period. MATERIAL AND METHODS: This is a prospective study of patients undergoing laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) between April 2018 and December 2018. The control group consists of patients who underwent various non-oncological elective surgical procedures. Patients' olfaction was tested qualitatively and quantitatively the day before and 24 h after surgery. Sniffin Sticks test consists of three subtests: odor threshold, discrimination, and identification. RESULTS: The study enrolled 83 patients (LSG = 39; LRYGB = 14; control = 30). Mean scores in the threshold subtest differed significantly in the bariatric group, 9.3 ± 3.9 before the surgery and 8.2 ± 3.0 a day after the surgery (p = 0.032). There were no significant differences between scores from the discrimination subtest, identification subtest and the mean total scores in the bariatric group. There was no observed change in the intensity of the smell in the control group. Analyzing the results of patients undergoing LSG and LRYGB separately, we only showed significant differences in the case of LSG. Mean score from the 1st test (9.12 ± 3.97 vs. 7.75 ± 2.98; p = 0.0339) and mean total score (32.83 ± 5.45 vs. 30.67 ± 4.88; p = 0.0173) differ between repetitive measurements in LSG patients. CONCLUSIONS: Our study shows deterioration of odor threshold in the bariatric surgery group compared to the control group 24 h after surgery. However, this change occurred only in patients undergoing LSG.

ABSTRACT

INTRODUCTION: Laparoscopic resection has become an accepted approach to liver tumour surgery. However, it is considered difficult, especially in unfavourably located lesions. AIM: To compare the outcomes of laparoscopic (LLR) and open liver resection (OLR) of posterolateral segments. MATERIAL AND METHODS: We searched the PubMed, EMBASE, and Scopus databases from inception to 30 September 2019. Full text articles and conference abstracts were included for further analysis. This review follows the PRISMA guidelines. RESULTS: From 643 articles, 15 studies (N = 1196 patients) were included in the meta-analysis. All of them were non-randomised. Our findings showed that LLR had significantly lowered overall morbidity compared to OLR (MD = 0.66; 95% CI: 0.51-0.86; p = 0.002). Length of hospital stay (MD = 2.48; 95% CI: -3.87, -1.08; p < 0.001) was also shorter in the LLR group. Operative time (MD = 55.65; 95% CI: 24.14-87.16; p < 0.001) was significantly shorter in the OLR group. In terms of blood loss, major complications, R0 resection rates, and resection margin, there were no significant differences. CONCLUSIONS: Our meta-analysis showed that the laparoscopic approach to resections of posterolateral liver segments is beneficial. However, the results are based on non-randomised trials, and further research is needed to fully establish their clinical application.

ABSTRACT

BACKGROUND & AIMS: Recently, a parameter called "Fragility index" (FI) has been proposed, which measures how many events the statistical significance relies on. The lower the FI the more "fragile" the results, and thus more care should be taken when interpreting the results. Our aim in this study was to check FI of nutritional trials. METHODS: We conducted a systematic review of human clinical nutrition RCTs that report statistically significant dichotomous primary outcomes. We searched the EMBASE, MEDLINE, and Scopus databases. The FI of primary outcomes using the Fisher exact test was calculated and checked the correlations of FI with the number of randomised trials, the p-value of primary outcomes, the publication date, the journal impact factor and the number of patients lost to follow-up. RESULTS: The initial database search revealed 5790 articles, 37 of which were included in qualitative synthesis. The median (IQR) FI for all studies was 1 (1-3). 28 studies (75.7%) had an FI lower or equal to 2, and in 12 (32.43%) articles, the FI was lower than the number of patients lost to follow-up. No correlations were found between FI and the study characteristics (number of randomized patients, p value of primary outcome, event ratio in experimental group, event ratio in control group, publication date, journal impact factor, lost to follow-up). CONCLUSION: The results of RCTs in nutritional research often rely on a small number of events or patients. The number of patients lost to follow-up is frequently higher than the FI calculation. Formulating recommendations based on RCTs should be done with caution and FI may be used as auxiliary parameter when assessing the robustness of their findings.

ABSTRACT

INTRODUCTION: Enhanced recovery after surgery (ERAS) pathways have been proven to enhance postoperative recovery, reduce morbidity, and reduce length of hospital stay after colorectal cancer surgery. However, despite the benefits of the ERAS program on short-term results, little is known about its impact on long-term results. OBJECTIVE: The aim of the study was to determine the association between adherence to the ERAS protocol and long-term survival after laparoscopic colorectal resection for non-metastatic cancer. MATERIAL AND METHODOLOGY: Between 2013 and 2016, 350 patients underwent laparoscopic colorectal cancer resection in the 2nd Department of General Surgery, Jagiellonian University Medical College, and were enrolled for further analysis. The relationship between the rate of compliance with the ERAS protocol and 3-year survival was analyzed according to the Kaplan-Meier method with log-rank tests. Patients were divided into two groups according to their degree of adherence to the ERAS interventions: Group 1 (109 patients), < 80% adherence, and Group 2 (241 patients), ≥ 80% adherence. The primary outcome was overall 3-year survival. The secondary outcomes were postoperative complications, length of hospital stay, and recovery parameters. RESULTS: The groups were similar in terms of demographics and surgical parameters. The median compliance to ERAS interventions was 85.2%. The Cox proportional model showed that AJCC III (HR 3.28, 95% CI 1.61-6.59, p = 0.0021), postoperative complications (HR 2.63, 95% CI 1.19-5.52, p = 0.0161), and compliance with ERAS protocol < 80% (HR 3.38, 95% CI 2.23-5.21, p = 0.0102) were independent predictors for poor prognosis. Additionally, analysis revealed that adherence to the ERAS protocol in Group 2 with ≥ 80% adherence was associated with a significantly shorter length of hospital stay (6 vs. 4 days, p < 0.0001), a lower rate of postoperative complications (44.7% vs. 23.3%, p < 0.0001), and improved functional recovery parameters: tolerance of oral diet (53.4% vs. 81.5%, p < 0.0001) and mobilization (77.7% vs. 96.1%, p < 0.0001) on the first postoperative day. CONCLUSIONS AND RELEVANCE: This study reports an association between adherence to the ERAS protocol and long-term survival after laparoscopic colorectal resection for non-metastatic cancer. Lower adherence to the protocol, independent from stage of cancer and postoperative complications, was an independent risk factors for poorer survival rates.

ABSTRACT

BACKGROUND: Aim of this study was to evaluate functional outcomes of transanal total mesorectal excision (TaTME) in comparison to conventional laparoscopic approach (LaTME) in terms of low anterior resection syndrome (LARS). METHODS: Forty-six patients who underwent total mesorectal excision for low rectal cancer between 2013 and 2017 were enrolled. Primary outcome was the severity of faecal incontinence, assessed both before the treatment and 6 months after ileostomy reversal. LARS score and Jorge-Wexner scale were utilized to analyze its severity. RESULTS: Twenty (87%) from TaTME and 21 (91%) from LaTME group developed LARS postoperatively. There were no significant differences between groups in terms of LARS occurrence (p = 0.63) and severity. The median Wexner score was comparable in both groups (8 [IQR: 4-12] vs 7 [3-11], p = 0.83). Univariate analysis revealed that postoperative complications were a risk factor for LARS development (p = 0.02). Perioperative outcomes, including operative time, blood loss and intraoperative adverse events did not differ significantly between groups either. Five TaTME patients developed postoperative complications, while there were morbidity 6 cases in LaTME group. Quality of mesorectal excision was comparable with 20 and 19 complete cases in TaTME and LaTME groups, respectively. CONCLUSIONS: TaTME provided comparable outcomes in terms of functional outcomes in comparison to LaTME for total mesorectal excision in low rectal cancers. Having said that, LARS prevalence is still high and requires further evaluation of the technique.

ABSTRACT

BACKGROUND AND OBJECTIVES: Laparoscopic splenectomy (LS) has become the gold standard for patients with immune thrombocytopenic purpura (ITP). The total remission rate after splenectomy is 70%-90%, of which 66% is long-term. Despite this high response rate, some patients do not benefit from surgery. It is therefore important to try to identify risk factors for an unsatisfactory clinical response. The aim of this study was to assess long-term outcomes of LS for ITP and identify factors associated with increased disease remission rates. MATERIALS AND METHODS: We retrospectively studied consecutive patients with ITP undergoing LS in a tertiary referral surgical center prospectively recorded in a database. Inclusion criteria were: Elective, laparoscopic splenectomy for diagnosed ITP, and complete follow-up. The cohort was divided into two groups-Group 1 (G1) patients with ITP remission after splenectomy and Group 2 (G2) patients without remission. There were 113 G1 patients and 52 G2 patients. Median follow-up was 9.5 (IQR: 5-15) years. RESULTS: In univariate analysis, patient's age, body mass index (BMI), preoperative platelet count, the need for platelet transfusions, and presence of hemorrhagic diathesis were shown to be statistically significant factors. Next, we built a multivariate logistic regression model using factors significant in univariate analysis. Age <41 years (odds ratio (OR) 4.49; 95% CI: 1.66-12.09), BMI <24.3 kg/m2 (OR: 4.67; 95% CI: 1.44-15.16), and preoperative platelet count ≥97 × 103/mm3 (OR: 3.50; 95% CI: 1.30-9.47) were shown to be independent prognostic factors for ITP remission after LS. CONCLUSION: The independent prognostic factors for ITP remission after LS revealed in our study are: age <41 years, BMI <24.3 kg/m2, and preoperative platelet count ≥97 × 103/mm3. Duration of the ITP and the time of treatment are not related to remission after LS.

ABSTRACT

BACKGROUND: Few investigations have been conducted that compared blood glucose in patients with diabetes mellitus (DM2) and morbid obesity who had undergone laparoscopic sleeve gastrectomy (LSG) or gastric bypass (LRYGB). We aimed to compare the effects of these procedures using continuous glucose monitoring (CGM). METHODS: We prospectively studied patients that had qualified for LSG or LRYGB. The inclusion criteria were DM2 of ≤ 5 years, for which patients were taking oral anti-diabetic drugs, or no glucose metabolism disorder; and morbid obesity. CGM was performed between admission and the 10th postoperative day. RESULTS: We studied 16 patients with DM2 and 16 without. Eighteen patients underwent LSG and 14 underwent LRYGB. The median hemoglobin A1c was 5.5% (5.4-5.9%) in DM2 patients, which did not differ from control (p = 0.460). Preoperative mean daily glucose concentration was similar between DM2 and control patients (p = 0.622). For patients with DM2, LRYGB was associated with more frequent low glucose status, and these episodes lasted longer than in DM2 patients that underwent LSG (p = 0.035 and 0.049, respectively). DM2 patients that underwent LRYGB demonstrated lower glucose concentrations from third postoperative day than those that underwent LSG. Patients without DM2 did not demonstrate differences in daily mean glucose concentrations, or in incidence nor duration of hypoglycemia throughout the observation period. CONCLUSION: A significantly larger reduction in interstitial glucose concentration is present from third day in patients with DM2 who undergo LRYGB vs. LSG, accompanied by a lower incidence and shorter duration of low glucose episodes.

ABSTRACT

BACKGROUND: The advantages of laparoscopy are widely known. Nevertheless, its legitimacy in liver surgery is often questioned because of the uncertain value associated with minimally invasive methods. Our main goal was to compare the outcomes of pure laparoscopic (LLR) and open liver resection (OLR) in patients with hepatocellular carcinoma. METHODS: We searched EMBASE, MEDLINE, Web of Science, and The Cochrane Library databases to find eligible studies. The most recent search was performed on December 1, 2017. Studies were regarded as suitable if they reported morbidity in patients undergoing LLR versus OLR. Extracted data were pooled and subsequently used in a meta-analysis with a random-effects model. Clinical applicability of results was evaluated using predictive intervals. Review was reported following the PRISMA guidelines. RESULTS: From 2085 articles, forty-three studies (N = 5100 patients) were included in the meta-analysis. Our findings showed that LLR had lower overall morbidity than OLR (15.59% vs. 29.88%, p < 0.001). Moreover, major morbidity was reduced in the LLR group (3.78% vs. 8.69%, p < 0.001). There were no differences between groups in terms of mortality (1.58% vs. 2.96%, p = 0.05) and both 3- and 5-year overall survival (68.97% vs. 68.12%, p = 0.41) and disease-free survival (46.57% vs. 44.84%, p = 0.46). CONCLUSIONS: The meta-analysis showed that LLR is beneficial in terms of overall morbidity and non-procedure-specific complications. That being said, these results are based on non-randomized trials. For these reasons, we are calling for randomization in upcoming studies. Systematic review registration: PROSPERO registration number CRD42018084576.

ABSTRACT

INTRODUCTION: Gastric cancer is a worldwide health concern, being one of the five most common malignant neoplasms worldwide. Currently, an open approach is the gold standard for surgical treatment. Incorporation of laparoscopy as a method of choice for gastric resections remains controversial because of limited evidence of eligibility. To date, there are no high-quality randomized quality trials on totally laparoscopic D2 total gastrectomies. AIM: The aim of this study was to assess currently available literature and provide meta-analysis on acquired data regarding short-term outcomes with a subgroup analysis of western and eastern studies. MATERIALS AND METHODS: We performed a systematic review and meta-analysis according to the PRISMA guidelines. The primary outcomes of interest were morbidity and short-term complications. RESULTS: An initial reference search yielded 3,073 articles. Finally, we chose eight studies covering 1,582 patients that we included in the quantitative analysis. We did not find statistical differences regarding operative time, anastomotic leakage, surgical site infection, cardiac complications, pulmonary complications, or number of harvested lymph nodes. We found significant differences regarding length of hospital stay and morbidity in the Asian population. CONCLUSION: This systematic review indicates that a laparoscopic approach for D2 total gastrectomy does not increase morbidity. Furthermore, it allows for a shorter hospital stay. However, more randomized controlled trials are required to fully assess this approach because available data are of limited quality.

ABSTRACT

The aim of our study was to evaluate the implementation and degree of adherence to the Enhanced Recovery after Surgery (ERAS) protocol in a group of 400 patients operated laparoscopically for colorectal cancer, and to assess its impact on the short-term results. The prospective study included patients with histologically confirmed colorectal cancer undergoing elective laparoscopic resection from years 2012 to 2017. For the purpose of further analysis, patients were divided into four groups: 100 consecutive patients were in each group. There were no statistically significant differences between groups in demographic parameters. The mean compliance with the ERAS protocol in the entire study group was 84.8%. Median adherence differed between the groups 76.9% vs. 92.3% vs. 84.6% vs. 84.6%, respectively (p < 0.0001). There were statistically significant differences between groups in the tolerance of oral diet (54% vs. 83% vs. 83% vs. 64%) and mobilization (74% vs. 92% vs. 91% vs. 94%) on the first postoperative day. In subsequent groups, time to first flatus decreased (2.5 vs. 2.1 vs. 2.0 vs. 1.7 days, p = 0.0001). There were no statistical differences in the postoperative morbidity rate between groups (p = 0.4649). The median length of hospital stay in groups was 5 vs. 4 vs. 4 vs. 4 days, respectively (p = 0.0025). Maintaining high compliance with the ERAS protocol is possible, despite the slight decrease that occurs within a few years after its implementation. This decrease in compliance does not affect short-term results, which are comparable to those shortly after overcoming the learning curve.

ABSTRACT

INTRODUCTION: Despite the progress in the treatment of colorectal cancer, there is still no optimal strategy for tumours located adjacent to the anal sphincter. This study aims to evaluate oncological and functional results of surgery for rectal cancer in unfavourable locations in proximity to anal sphincters. MATERIALS AND METHODS: Patients with rectal cancer, which was either initially infiltrating the anal sphincter or located in the close proximity of the sphincter, were included in the study. Patients were submitted to extralevator abdominoperineal resection (APR), intersphincteric resection, or transanal total mesorectal excision (TaTME). Primary outcomes were perioperative data: operative time, blood loss, complications, length of stay (LOS), and 30-day mortality. Secondary outcomes were pathological quality of the specimens and functional outcome 6 months after defunctioning ileostomy closure. RESULTS: Among patients with cancer adjacent to the anal sphincter, 13 (25%) underwent APR, 14 (27%) patients were submitted to intersphincteric resection, and 25 (48%) patients were treated with the TaTME approach. Operative time was 240 (210-270 IQR) for APR, 212.5 (170-260 IQR) for intersphincteric resection, and 270 (240-330 IQR) for TaTME (p = 0.018). Perioperative morbidity was 31% for APR, 36% for intersphincteric resections, and 12% for the TaTME group (p = 0.181). Complete mesorectal excision was achieved in 92% of specimens in the TaTME group, 93% in intersphincteric resections, and 78% in the APR group (p = 0.72). Median circumferential resection margin in APR was 6 mm (4-7 IQR), in intersphincteric resections 7.5 mm (2.5-10 IQR), and in the TaTME group 4 mm (2.8-8 IQR). All patients after intersphincteric resections developed major low anterior resection syndrome (LARS). Four patients in the TaTME group developed minor LARS, and 21 had major LARS. CONCLUSION: Sphincter-saving rectal resections are a feasible alternative to APR with good clinical, pathological, and oncological outcomes. Intersphincteric resections and TaTME seem to be equal in terms of clinicopathological results. The functional outcome is yet to be investigated. TRIAL REGISTRATION: The study was retrospectively registered in Thai Clinical Trials Registry (23-07-2018, ID TCTR20180724001 ).

ABSTRACT

INTRODUCTION: Laparoscopic surgery is an approved technique in colorectal cancer treatment. Functional and quality-of-life studies have revealed significant changes in faecal continence. AIM: To assess the incidence and risk factors of low anterior resection syndrome (LARS) in patients undergoing rectal resections for cancer. MATERIAL AND METHODS: We enrolled patients undergoing rectal resections in a general surgery department of a university hospital. The primary outcomes were the Jorge-Wexner scale and the LARS score 6 months after the end of treatment. The secondary outcomes were the risk factors for LARS development. RESULTS: Fifty-six patients were included; 15 (26%) developed major LARS and 10 (18%) had minor LARS at 6 months. In univariate analysis the risk factors were: preoperative radiotherapy (p < 0.001, OR = 11.9, 95% CI: 2.98-47.48); shorter distance of the tumour from the anal verge (p = 0.001, OR = 0.69, 95% CI: 0.55-0.86); bowel preparation (p = 0.01, OR = 6.27, 95% CI: 1.51-26.07); low anterior rectal resection (p = 0.01, OR = 17.07, 95% CI: 1.86-156.83); and protective ileostomy (p = 0.001, OR = 15.97, 95% CI: 4.07-61.92). The risk factors for a higher Jorge-Wexner score in univariate analysis were greater diameter of tumour (p = 0.035), radiotherapy (p = 0.001), shorter distance from the anal verge (p = 0.002), bowel preparation (p = 0.042), low anterior rectal (LAR) (p = 0.01), ileostomy (p = 0.001), perioperative complications (p = 0.032), and readmission within 30 days (p = 0.034). In the multivariate analysis, readmissions and perioperative complications were significant. CONCLUSIONS: In addition to typically described risk factors, two new ones have been identified. Mechanical bowel preparation and defunctioning ileostomy may also contribute to LARS development. However, due to the limitations of this study our observations require further confirmation in future trials.

ABSTRACT

INTRODUCTION: Postoperative morbidity after colorectal resections for cancer remains a significant problem. Data on the influence of complications on survival after laparoscopic colorectal resection are still limited. AIM: To analyze the impact of postoperative complications on long-term survival after radical laparoscopic resection for colorectal cancer. MATERIAL AND METHODS: Two hundred and sixty-five consecutive non-metastatic colorectal cancer patients undergoing laparoscopic colorectal resection for cancer were included in the analysis. The entire study group was divided into two subgroups based on the occurrence of postoperative complications. Group 1 included patients without postoperative morbidity and group 2 included patients with complications. The primary outcome was overall survival. RESULTS: Median follow-up was 45 (IQR: 34-55) months. Group 1 consisted of 187 (70.5%) patients and group 2 comprised 78 (29.5%) patients. Studied groups were comparable in terms of sex, age, body mass index, ASA class, cancer staging, localization of the tumor and operative time. Patients in group 1 had significantly better overall 3-year survival compared to those with complications (84.9% vs. 69.8%, p = 0.022). Kaplan-Meier curves showed significantly improved survival rates in patients without complications compared with complicated cases. The Cox proportional multivariate model showed that postoperative complications (HR = 2.83; 95% CI: 1.35-5.92; p = 0.0058) and AJCC III (HR = 3.17; 95% CI: 1.52-6.6; p = 0.0021) were independent predictors of worse survival after laparoscopic colorectal cancer surgery. CONCLUSIONS: Our analysis of interim results after 3 years confirms that complications after laparoscopic colorectal cancer surgery have an impact on survival. For this reason, these patients should be carefully monitored after surgery aiming at early detection of recurrence.

ABSTRACT

BACKGROUND: The prevalence of obesity is growing worldwide. Malnutrition has been identified as a risk factor, leading to higher morbidity rate and prolonged length of hospital. So far there are no high quality data on the impact of malnutrition on length of hospital stay and morbidity regarding bariatric surgery. The aim of the study was to assess association between nutritional status and outcomes bariatric surgeries. MATERIAL AND METHODS: The study was a prospective observational study. INCLUSION CRITERIA: informed consent to participate in the study, age 18-65 years, meeting the eligibility criteria for bariatric treatment, qualification for laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux-en-Y Gastric By-pass (LRYGB). EXCLUSION CRITERIA: revision surgery, lack of necessary data. The primary endpoint was the evaluation of protein malnutrition risk prevalence. Secondary: influence of malnutrition risk patients' on treatment course and postoperative complications. RESULTS: 533 patients met inclusion criteria and were analyzed. 169 patients (32%) had qualitative risk of malnutrition. The body mass index (BMI) was significantly higher in malnutritioned group, p = 0.001. Albumins in malnutritioned group was 38 g/l (IQR 35-42), whereas in control group it was 41 g/l (IQR 39-43), p = 0.027. Lymphocyte count in malnutrition risk group and control group were 1.24 10'3/µl (IQR 1.1-1.37) and 1.94 10'3/µl (IQR1.7-2.3) respectively, p < 0.001. In linear regression model, a correlation between BMI and total number of lymphocytes was present, p < 0.001. Malnutrition risk did not affect the total morbidity rate. There was a difference in occurrence of postoperative nausea and vomiting, p = 0.033. CONCLUSIONS: Higher BMI is associated with greater risk of malnutrition. Proper perioperative care may diminish the impact of malnutrition on adverse effects and length of stay (LOS).

ABSTRACT

OBJECTIVES: The role of a defunctioning ileostomy in every anterior rectal resection with total mesorectal excision (TME) is still controversial. In this study, we aimed to review the current literature to determine the impact of ileostomy creation on postoperative outcomes in patients undergoing anterior rectal resection with TME. METHODS: MEDLINE, Embase and Cochrane Library were searched for eligible studies. We analyzed data up to October 2017. Eligible studies had to compare patients with vs. without a defunctioning ileostomy in rectal cancer surgery and comprise data on anastomotic leakage in both groups. The primary outcome was anastomotic leakage. Secondary outcomes included the complication rate, mortality, reoperation rate, length of hospital stay and 30-day readmission. RESULTS: Initial search yielded 1,966 articles. Thorough evaluation resulted in 13 eligible articles which were analyzed. Leakage rate (RR = 0.43, 95% CI 0.28-0.67) and the number of reoperations (RR = 0.62, 95% CI 0.40-0.94) were significantly lower in the defunctioning stoma group. Morbidity was significantly higher in the stoma group (RR = 1.32, 95% CI 1.05-1.65). Analysis of mortality, length of hospital stay and readmission rate did not show any significant differences. CONCLUSION: A defunctioning ileostomy may decrease the anastomotic leakage rate, additionally significantly reducing the risk of reoperations but it may also increase the overall complication rate. The presence of the protective stoma has no effect on mortality, length of hospital stay and readmission rate.

ABSTRACT

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) and laparoscopic gastric bypass (LRYGB) are most commonly performed bariatric procedures. Laparoscopic approach and enhanced recovery after surgery (ERAS) protocols managed to decrease length of hospital and morbidity. However, there are patients in whom, despite adherence to the protocol, the length of stay (LOS) remains longer than targeted. This study aimed to assess potential risk factors for prolonged LOS and readmissions. METHODS: The study was a prospective observation with a post-hoc analysis of bariatric patients in a tertiary referral university teaching hospital. Inclusion criteria were undergoing laparoscopic bariatric surgery. Exclusion criteria were occurrence of perioperative complications, prior bariatric procedures, and lack of necessary data. The primary endpoints were the evaluations of risk factors for prolonged LOS and readmissions. RESULTS: Median LOS was 3 (2-4) days. LOS > 3 days occurred in 145 (29.47%) patients, 79 after LSG (25.82%) and 66 after LRYGB (35.48%; p = 0.008). Factors significantly prolonging LOS were low oral fluid intake, high intravenous volume of fluids administered on POD0, and every additional 50 km distance from habitual residence to bariatric center. The risk of hospital readmission rises with occurrence of intraoperative adverse events and low oral fluid intake on the day of surgery on. CONCLUSIONS: Risk factors for prolonged LOS are low oral fluid intake, high intravenous volume of fluids administered on POD0, and every additional 50 km distance from habitual residence. Risk factors for hospital readmission are intraoperative adverse events and low oral fluid intake on the day of surgery.

ABSTRACT

Most current guidelines do not recommend primary tumor resection in stage IV unresectable colorectal cancer. Rapid chemotherapy development over the last decade has substantially changed the decision making. However, results of recently published trials and meta-analyses suggest that primary tumor resection may in fact be beneficial, principally in terms of prolonged survival. Additional factors, such as use of minimally invasive approach or protocols of enhanced recovery after surgery, affect clinical outcomes as well, but are often neglected when discussing the state of the art in this area. There are still no randomized studies determining the legitimacy of upfront surgery in asymptomatic patients. Also, quality of life also plays an important role in choosing appropriate treatment. Having said that, there is no data that would prove whether primary tumor resection has an advantage on that issue. With all the uncertainty, currently decision making in unresectable stage IV colorectal cancer is primarily up to clinicians' knowledge, common sense and patients' preferences.
