RESUMO
Globally, an increasing prevalence of colorectal cancer (CRC) prompts a need for the development of new methods for early tumor detection. MicroRNAs (also referred to as miRNAs) are short non-coding RNA molecules that play a pivotal role in the regulation of gene expression. MiRNAs are effectively transferred to extracellular vesicle (EVs) membrane sacs commonly released by cells. Our study aimed to examine the expression of miRNAs in four CRC cell lines and EVs derived from them (tumor EVs) in comparison to the normal colon epithelium cell line and its EVs. EVs were isolated by ultracentrifugation from the culture supernatant of SW480, SW620, SW1116, HCT116 and normal CCD841CoN cell lines and characterized according to the MISEV2023 guidelines. MiRNAs were analyzed by small RNA sequencing and validated by quantitative PCR. The performed analysis revealed 22 common miRNAs highly expressed in CRC cell lines and effectively transferred to tumor EVs, including miR-9-5p, miR-182-5p, miR-196b-5p, miR-200b-5p, miR-200c-3p, miR-425-5p and miR-429, which are associated with development, proliferation, invasion and migration of colorectal cancer cells, as well as in vesicle maturation and transport-associated pathways. In parallel, normal cells expressed miRNAs, such as miR-369 and miR-143, which play a role in proinflammatory response and tumor suppression. The analysis of selected miRNAs in plasma-derived EVs and tumor samples from CRC patients showed the similarity of miRNA expression profile between the patients' samples and CRC cell lines. Moreover, miR-182-5p, miR-196-5p, miR-425-5p and miR-429 were detected in several EV samples isolated from patients' plasma. Our results suggest that miR-182-5p, miR-196b-5p and miR-429 are differentially expressed between EVs from CRC patients and healthy donors, which might have clinical implications.
RESUMO
Introduction: Endovascular aortic repair (EVAR) is nowadays a widespread method of managing abdominal aortic aneurysm (AAA). Low-profile stent grafts (LPSGs) enable treatment of patients with complex and anatomically challenging aneurysms, and facilitate a percutaneous and thus less invasive procedure. Aim: To assess the outcomes of EVAR with low-profile versus standard-profile stent grafts (SPSGs). Material and methods: Thirty-one patients with abdominal aortic aneurysms (AAA) were treated by endovascular aortic repair (EVAR) using LPSGs. The control group of patients treated with SPSGs was matched with MedCalc software. The clinical records and the preoperative and follow-up computed tomography angiography of patients who underwent endovascular treatment of AAA were included in this study. Results: Patients in the LPSG group had significantly more often low access vessel diameter (< 6 mm) compared to the SPSG group (38.7% vs. 6.7%, p = 0.003). In 1-year follow-up, there was no rupture, no infection, no conversion to open repair and no aneurysm-related death. Five secondary interventions were necessary in the SPSG group and only 1 in the LPSG group (p = 0.09). Type of stent graft was not a risk factor of perioperative complications, presence of endoleak or reintervention (p > 0.05). Risk factors for perioperative complications were COPD and conical neck (OR = 6.3, 95% CI: 1.5-25, p = 0.01 and OR = 6.2, 95% CI: 1-39.76, p = 0.04). The risk factor for endoleak was lower maximal aneurysm diameter. The risk factor for reintervention was proximal neck diameter (OR = 0.77, 95% CI: 0.-0.97, p = 0.03). Conclusions: Our study showed that use of LPSGs is a safe and viable method for patients with narrow access vessels who are not eligible for standard-profile systems.
RESUMO
Introduction: A narrow pelvis, obesity, and bulky low rectal tumor are perceived as risk factors for intraoperative difficulties during total mesorectal excision (TME), particularly in the laparoscopic approach. A transanal approach has been developed to overcome the difficulties encountered during laparoscopic TME. There is no clear definition of a narrow pelvis that would guide preoperative surgical planning. Aim: To evaluate different MRI-based pelvic measurements in patients undergoing TME to identify factors predictive of intraoperative difficulties in transabdominal compared to the transanal approach. Material and methods: A retrospective analysis of 48 patients treated with laparoscopic TME and 62 with transanal TME for rectal tumors was performed. Multiple logistic regressions analyzed demographic, tumor, and pelvimetry factors that correlate with intraoperative difficulties measured as intraoperative blood loss, operation time, and perioperative complications in both surgical approaches. Results: Multivariate analysis showed that age was associated with higher blood loss (OR = 1.09, 95% CI: 1.00-1.18, p = 0.038), male gender (OR = 0.13, 95% CI: 0.02-0.86, p = 0.029) and body mass index with longer operating time (OR = 1.32, 95% CI: 1.06-1.64, p = 0.010) in the LAR group. Multivariate analysis showed that age increased the odds of intraoperative blood loss > 100 ml (OR = 1.08, 95% CI: 1.02-1.15, p = 0.013), and pelvic length > 119 mm increased operating time (OR = 5.76, 95% CI: 1.33-25.01, p = 0.016) in the TaTME group. Conclusions: Pelvic measurements are not associated with intraoperative difficulties in LAR. Longer pelvis was associated with longer operative time in TaTME.
RESUMO
Background and Objectives: The growing and aging population of hemodialysis patients has become increasingly disabled, with more complex comorbidities, and are older upon initiating dialysis. Visual impairment can adversely affect their quality of life and life satisfaction. Treatment evaluation should not only consider remission of the disease, but also the improvement of quality of life and life satisfaction. This is a single-center cross-sectional study. It was designed to evaluate visual impairment in hemodialyzed patients, its correlation with quality of life and life satisfaction, and its relationship to clinical outcomes in hemodialyzed patients. Materials and Methods: Seventy patients with chronic kidney disease undergoing hemodialysis and aged 18 years or older were recruited from a single Dialysis Unit. The Impact of Visual Impairment Scale (IVIS), WHOQOL-BREF, and Cantril Ladder questionnaires were utilized to assess both sociodemographic and clinical variables. Results: It was found that, among all assessed variables (i.e., sex, marital status, level of education, months on hemodialysis, history of kidney transplantation, Kt/V, URR, and UF), only age and central venous catheter placement were positively correlated with IVIS scores, while arteriovenous fistula and willingness to become a kidney transplant recipient were negatively correlated. Furthermore, a comparison between patients with moderate and severe visual impairment yielded supplemental data indicating that individuals whose dialysis access was through a dialysis catheter and those ineligible or unwilling to undergo transplantation suffered more often from severe visual impairment. This finding may be attributed to age. Conclusions: Older patients were predominantly observed to experience visual impairment. Patients intending to receive a kidney transplant and whose dialysis access was through an arteriovenous fistula were less prone to visual impairment, compared to those who may be ineligible or unwilling to receive transplantation and those with hemodialysis catheters. This phenomenon can be attributed to age-related distinctions in patients' suitability for specific dialysis access and transplantation. Those reporting visual impairment gave lower ratings in all four domains of their quality of life (comprising physical health, psychological health, social relationships, and environment) and in both present and anticipated five-year life satisfaction. More severe visual impairment was related to an additional reduction in physical health, social relationship, and environment domains, and in life satisfaction.

INTRODUCTION: As the number of elderly patients requiring surgical intervention rises, it is believed that frailty syndrome has a greater impact on perioperative course than on chronological age. The aim of this study was to evaluate the efficacy of various imaging features for frailty assessment in patients undergoing emergency laparotomy. METHODS: The study included all patients that qualified for emergency surgery with preoperative CT scans between 2016 and 2020 in the Second Department of General Surgery. Multiple trauma patients were excluded from the analysis. The modified frailty index and brief geriatric assessment were used in the analysis. CT images were reviewed for the assessment of osteopenia, sarcopenia, sarcopenic obesity, renal volume and abdominal aorta calcification rate. RESULTS: A total of 261 patients were included in the analysis. Multivariate logistic regression identified every next ASA class (OR: 4.161, 95%CI: 1.672-10.355, p = 0.002), intraoperative adverse events (OR: 12.397, 95%CI: 2.166-70.969, p = 0.005) and osteopenia (OR: 4.213, 95%CI: 1.235-14.367, p = 0.022) as a risk factor for 30-day mortality. Our study showed that every next ASA class (OR: 1.952, 95%Cl: 1.171-3.256, p = 0.010) and every point of the BGA score (OR: 1.496, 95%Cl: 1.110-2.016, p = 0.008) are risk factors for major complications. CONCLUSIONS: Osteopenia was the best parameter for perioperative mortality risk stratification in patients undergoing emergency surgical intervention. Sarcopenia (measured as psoas muscle area), sarcopenic obesity, aortic calcifications and mean kidney volume do not predict poor outcomes in those patients. None of the radiological markers appeared to be useful for the prediction of perioperative morbidity.
RESUMO
Colorectal cancer (CRC) is the third most common malignancy. Its development and progression is associated with natural immunosuppression related, among others, to myeloid derived suppressor cells (MDSCs). Overall, 54 patients in different stage of CRC, before any treatment were recruited into the study. The analysis included flow cytometry evaluation of blood MDSCs subsets, correlation their level with the tumor stage and T cell subsets. In the case of 11 patients, MDSCs level was evaluated before and 3 days after surgery, and these patients were monitored for cancer recurrence over 5 years. The results showed that frequency of circulating MDSCs subsets is increased significantly in CRC patients, with highest level detected in most advanced tumor stages. Moreover, only monocytic MDSCs (Mo-MDSCs) positively correlate with regulatory Treg, and negatively with tumor Her2/neu specific CD8+ T cells. Circulating MDSCs, in contrast to tumor resident (mostly Mo-MDSCs), are negative for PD-L1 expression. Additionally, after surgery the blood level of Mo-MDSCs increases significantly, and this is associated with tumor recurrence during a 5-year follow-up. In conclusion, Mo-MDSCs are pivotal players in CRC-related immunosuppression and may be associated with the risk of tumor recurrence after surgery.
RESUMO
INTRODUCTION: Epidemiology and the outcomes of acute appendicitis in elderly people are very different from the younger patients. Aim of this study was to investigate the significance of frailty syndrome in the course of acute appendicitis. METHODS: All patients over 65 years old who underwent laparoscopic appendectomy between 2013 and 2021 in 2nd Department of General Surgery were included in the study. In our assessment Modified Frailty Index and Brief Geriatric Assessment were performed. RESULTS: In the analyzed period 106 appendectomies were performed in patients over 65 years old. Postoperative complications occurred in 13 patients (12.3%). Prolonged hospitalization (over 3 days) was observed in 48 patients (45.3%). Multivariate analysis showed that every ASA class (OR=2.406; 95% CI 1.089-5.316; p=0.030) and postoperative complication (OR=5.692; 95% CI 1.077-30.073; p=0.041) are risk factors for prolonged hospitalization. Our study identified diabetes (OR=5.956; 95% CI 1.391-25.510; p=0.016) as a risk factor for postoperative complications. CONCLUSIONS: According to our study Modified Frailty Index and Brief Geriatric Assessment does not correlate with prolonged hospitalization or higher risk for postoperative complication after appendectomy in elderly people.

INTRODUCTION: Sleeve gastrectomy has become one of the most performed bariatric procedures. There is increasing evidence that sleeve gastrectomy patients suffer from gastroesophageal reflux disease and its sequelae such as erosive oesophagitis (EO) or Barret's oesophagus (BO). AIM: To evaluate the incidence of EO and BO among patients with normal preoperative oesophagogastroduodenoscopy findings, who underwent sleeve gastrectomy, and investigate factors that may contribute to the development of EO and BO after the surgery. MATERIAL AND METHODS: We conducted a single-centre longitudinal study that included patients who underwent sleeve gastrectomy and completed 5 years of follow-up. Gastroscopies were performed in all patients at the end of the follow-up period. Patient- and treatment-related factors were used to search for risk factors of BO. RESULTS: From a total of 30 patients, symptomatic reflux was reported by 17 (56.7%) during the follow-up period. At EGD EO was found in 9 of those patients (30%), whereas BE was diagnosed in 8 (27%) patients. The median BMI at the end of the follow-up period was significantly higher among patients with BE than in the groups with EO and with no endoscopic changes: 40.91 ±6.32, 32.42 ±5.53, and 33.25 ±4.41, respectively (p = 0.04). CONCLUSIONS: The prevalence of BO in SG patients is considerable. The risk of BE increases in patients with poor bariatric outcome. Endoscopic surveillance should be considered as part of the follow-up, especially in patients with higher overall risk of BE.
RESUMO
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.

INTRODUCTION: Surgery is the first choice of treatment for colorectal cancer. Nutritional support in the form of oral nutritional supplements (ONSs) in the preoperative period is widely accepted for reducing the incidence of perioperative complications, and immunonutrition is generally recommended. However, there is little clinical data regarding the impact of such treatment on tumor biology. MATERIAL AND METHODS: In this study, tumor tissue and blood samples were collected from 26 patients during preoperative colonoscopy at the time of clinical diagnosis (sample A). Group 1 received standard ONSs (3× Nutricia Nutridrink Protein per day) for 2 weeks before surgery. In group 2, immune ONSs (2× Nestle Impact Oral) were administered for the same duration. Tumor tissue (sample B) was then retrieved from the tumor after resection. Changes in the expression levels of inflammatory cytokines (TNF-α, interleukin 8 or chemokine (C-X-C motif) ligand (CXCL8), stromal cell-derived factor 1 (SDF1a), chemokine (C-X-C motif) ligand 6 (CXCL6), chemokine (C-X-C motif) ligand (CXCL2), myeloperoxidase (MPO), and CXCL1) were assessed during the perioperative course. RESULTS: TNF-α expression differed after intervention between the two groups (immune group 31.63 ± 13.28; control group 21.54 ± 6.84; p = 0.049) and prior to and after intervention in the control group (prior to intervention 35.68 ± 24.41; after intervention 21.54 ± 6.84; p = 0.038). Changes in CXCL8 expression in the control group occurred prior to and after intervention (prior to intervention 2975.93 ± 1484.04; after intervention 1584.85 ± 1659.84; p = 0.041). CXCL1 expression was increased in the immune group and decreased in the control group (immune group 2698.27 (1538.14-5124.70); control group 953.75 (457.85-1534.60); p = 0.032). In both groups, a decrease in superficial neutrophil infiltration was observed, but this was only statistically significant in the immune group. There was no impact of the observed differences between the two groups on surgical outcomes (morbidity, length of stay, readmissions). CONCLUSIONS: Immunonutrition in the preoperative period compared with standard nutritional support may influence inflammatory cytokine expression and leukocyte infiltration in patients with colorectal cancer.
RESUMO
PURPOSE: Laparoscopic sleeve gastrectomy (LSG) is one of the most commonly performed bariatric procedure worldwide. Omentopexy during LSG is a novel variation of this well-established technique. There are no clear conclusions on indications for this procedure, safeness, and effects of such a method. We aimed to compare the outcomes of laparoscopic sleeve gastrectomy (LSG) with omentopexy (OP) and without omentopexy. MATERIALS AND METHODS: We searched the Medline, EMBASE, and Scopus databases up-to June 2020. Full-text articles and conference abstracts were included for further analysis. This review follows the PRISMA guidelines. RESULTS: Of initial 66 records, only 4 studies (N = 1396 patients) were included in the meta-analysis. Our findings showed that LSG with omentopexy had significantly lowered overall morbidity compared to LSG without omentopexy (RR = 0.38; 95% CI [0.15, 0.94]; p=0.04). Gastric leakage rate (RR = 0.17; 95% CI [0.04, 0.76]; p = 0.02) was also significantly lower in LSG with omentopexy. There were no significant differences between groups in length of hospital stay. CONCLUSIONS: Our meta-analysis showed that LSG with omentopexy may be a feasible procedure for decreasing morbidity and gastric leak rate. However, despite promising results, the procedure needs to be researched more in randomized controlled studies to draw solid conclusions.

PURPOSE: Children with a history of brain tumors do not appear to be at a significantly higher risk of sports-related injuries. Nevertheless, according to the systematic review and survey conducted by Perreault et al., 75% of healthcare professionals restrict their patients' participation in physical activities after brain tumor surgery. The aim of our study was to verify whether children after brain tumor surgery return to physical education (PE) classes. It was also an attempt to explore factors limiting return to physical activity. METHODS: Patients after brain tumor surgery, ≤ 18 years old on admission with ≥ 1 year follow-up were included in the analysis. Data concerning the disease were collected and summarized in search of factors limiting return to physical activity. Meticulous information about return to sports and physical education at school was gathered during follow-up visits. RESULTS: 71.43% of patients returned to school sports activities. Children who did not return to PE had markedly higher neoplasm WHO grade. Significant differences were also found between the groups in terms of hydrocephalus occurrence and need for additional oncological treatment. In univariate analysis, we identified neoplasm WHO grade, tumor location, presence of neurological deficit after the procedure, additional oncological treatment, and occurrence of hydrocephalus needing shunting as the risk factors for not returning to school physical education. CONCLUSIONS: The majority of pediatric brain tumor survivors return safely to physical education. Higher neoplasm WHO grade, presence of neurological deficit after the procedure, additional oncological treatment, and occurrence of hydrocephalus are risk factors for not returning to physical education.

INTRODUCTION: The ERAS (Enhanced Recovery after Surgery) protocol revolutionized perioperative care for gastrointestinal surgical procedures. However, little is known about the association between adherence to the ERAS protocol in gastric cancer surgery and the oncological outcome. AIM: To explore the relation between adherence to the ERAS protocol and the oncological outcome in gastric cancer patients. MATERIAL AND METHODS: We performed a retrospective analysis of a prospectively collected database of patients treated for gastric cancer between 2013 and 2016. All patients were treated perioperatively with a 14-item ERAS protocol. Every patient underwent regular follow-up every 3 months for 3 years after surgery. 80% compliance to the ERAS protocol was the goal during perioperative care. Based on the level of compliance, patients were divided into group 1 and group 2 (compliance of ≥ 80% and < 80%, respectively). RESULTS: Compliance to the ERAS protocol was not a risk factor for diminished overall survival - probability of 3-year survival was 63% in group 1 and 56% in group 2 (p = 0.75). The proportional Cox model revealed that only stage III gastric cancer was a risk factor of poor prognosis in patients operated on for gastric cancer (HR = 7.89, 95% CI: 2.96-20.89; p = 0.0001). CONCLUSIONS: High adherence to the ERAS protocol did not improve overall survival in our 3-year observation. Only the stage of the disease, according to the AJCC classification, was identified as a risk factor for poor prognosis.
RESUMO
INTRODUCTION: Cholecystolithiasis is one of the most frequent disorders of the human digestive system in a present population. It is common to point out that male gender is one of strong risk factors for complications during cholecystectomy, however the debate about that seems to be still open. AIM OF THE STUDY: The aim of this study was to compare the values related to the course and treatment effects between gender in patients undergoing cholecystectomy, based on own material. MATERIALS AND METHODS: The study encompassed 504 patients who were admitted to General Surgery And Polytraumatic Injury Department of University Hospital in Kraków, Poland between 2013 and 2018, with the initial diagnosis of cholecystolithiasis (scheduled cases) and acute cholecystitis (emergency cases). The patients underwent surgical gallbladder removal. In this group there were 326 (64.7%) female and 178 (35.3%) male patients. RESULTS: Statistically significant differences between both genders were found containing age, type of admission, numeric rating scale of pain during admission, results in American Society of Anesthesiologists physical status classification system, outcomes in Acute Physiology And Chronic Health Evaluation II severity-of-disease classification system, percentage of conversions, mortality, period of time from admission to surgical procedure, mean duration of the procedure, blood tests and histopathological results. CONCLUSIONS: Subgroups of the cases where determining factor is gender are strongly heterogeneous. Although treatment results were different for both subgroups and these differences were partly statistically significant, it cannot be clearly determined on the basis of a study with such selection of patients, that gender is an independent risk factor for surgical gallbladder removal.

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.
RESUMO
BACKGROUND: Abdominal pain is one of the most common complaints among patients admitted to the Emergency Department (ED). Diagnosis and management of abdominal pain may be a challenge and there are patients who require admission to the ED more than once in a short period of time. Our purpose was to assess the incidence of readmissions among patients treated in the ED due to abdominal pain and to investigate the impact of readmission on the further course of treatment. METHODS: We conducted a prospective observational study, which included patients admitted to the ED in one academic, teaching hospital presenting with non-traumatic abdominal pain in a three-month period. Analyzed factors included demographic data, details related to first and subsequent visits in the ED and the course of hospitalization. RESULTS: Overall, 928 patients were included to the study and 101 (10.88%) patients were admitted to the ED more than once during three-month period. Patients visiting ED repeatedly were older (p = 0.03) and more likely to be hospitalized (p < 0.01) compared to single-visit patients. Patients during their subsequent visits spent more time in the ED (p = 0.01), had greater chance to repeat their appointment (p = 0.04), be admitted to the hospital (p < 0.01) and were more likely diagnosed with cholelithiasis (p = 0.03) compared to patients on their initial visit. If admitted to the surgical department they were also more often qualified for surgical procedure than patients on their first visit (p < 0.01). In a group of patients admitted to the surgical department there were no significant differences in rates of conversion, postoperative complications and mortality between subgroups. CONCLUSIONS: Readmissions among patients presenting with abdominal pain are a common phenomenon with prevalence of 10.88%. They are most commonly associated with cholelithiasis and occur more frequently among older patients, which suggests, that elderly require more attention during ED managements.

BACKGROUND: The number of bariatric procedures is growing worldwide annually. While there is no doubt that a high body mass index is fundamental in qualification for surgical intervention, the Edmonton Obesity Staging System (EOSS) developed in 2009 may be an additional tool for identifying patients for whom surgery should be performed and those for whom the surgery should be postponed. OBJECTIVE: Assessment of the feasibility of modified EOSS as a qualification tool for surgery for obesity and related diseases and its association with morbidity. SETTING: University Hospital, Jagiellonian University Medical College, Cracow, Poland. METHODS: A retrospective study of prospectively collected data. All patients were assigned an EOSS score based on their medical record. We only considered the medical aspect, so the achieved results may be underpowered. Analyzed outcomes involved specific and overall complication rate, length of hospital stay, and weight loss. Regression models were created to assess the influence of EOSS on length of stay and complications. RESULTS: We included 761 patients who were operated on between 2009 and 2018 in our department. Of these, 505 patients received sleeve gastrectomy and 256 patients received Roux-en-Y gastric bypass. The median EOSS score was 2, which was assigned to 80% of the patients. The analysis showed no influence of modified EOSS on peri- or postoperative outcomes. Additionally, there were no significant differences in the number of patients who achieved bariatric success. The follow-up rate at 1 year was 70%. CONCLUSIONS: Our study suggests that modified EOSS score has no influence on the risk of developing complications and prolonged hospital stay. Patients with an EOSS score of ≥3 have higher major complication rate.

INTRODUCTION: Transanal total mesorectal excision (TaTME) has been recently proposed to overcome the difficulties of the standard TME approach, allowing better visualization and dissection of the mesorectal fascia. Although TaTME seems very promising, the evidence and body of knowledge on achieving proficiency in performing it are still sparse. AIM: To evaluate the learning curve of TaTME based on a single centre's experience. MATERIAL AND METHODS: Consecutive patients undergoing TaTME since 2014 in a tertiary referral department were included in the study. All procedures were performed by one experienced surgeon. CUSUM curve analyses were performed to evaluate learning curves. RESULTS: Sixty-six patients underwent TaTME. After analysis of postoperative morbidity rate, intraoperative adverse effects and operative time, we estimated that 40 cases are needed to achieve TaTME proficiency. Subsequently, patients were divided into two groups: before (40 patients) and after overcoming the learning curve (26 patients). Group 1 had higher readmission (p = 0.041) and complication rates (p = 0.019). There were no statistically significant differences in terms of intraoperative adverse effects, length of stay or pathological quality of the specimen. CONCLUSIONS: Transanal total mesorectal excision is a promising yet technically demanding procedure and requires at least 40 cases to complete the learning curve. More data are needed to introduce it as a standard procedure for low rectal cancer treatment.
RESUMO
OBJECTIVES: The aim of this study was to evaluate impact of 3D printed models on decision-making in context of laparoscopic liver resections (LLR) performed with intraoperative ultrasound (IOUS) guidance. METHODS: Nineteen patients with liver malignances (74% were colorectal cancer metastases) were prospectively qualified for LLR or radiofrequency ablation in a single center from April 2017 to December 2018. Models were 3DP in all cases based on CT and facilitated optical visualization of tumors' relationships with portal and hepatic veins. Planned surgical extent and its changes were tracked after CT analysis and 3D model inspection, as well as intraoperatively using IOUS. RESULTS: Nineteen patients were included in the analysis. Information from either 3DP or IOUS led to changes in the planned surgical approach in 13/19 (68%) patients. In 5/19 (26%) patients, the 3DP model altered the plan of the surgery preoperatively. In 4/19 (21%) patients, 3DP independently changed the approach. In one patient, IOUS modified the plan post-3DP. In 8/19 (42%) patients, 3DP model did not change the approach, whereas IOUS did. In total, IOUS altered surgical plans in 9 (47%) cases. Most of those changes (6/9; 67%) were caused by detection of additional lesions not visible on CT and 3DP. CONCLUSIONS: 3DP can be helpful in planning complex and major LLRs and led to changes in surgical approach in 26.3% (5/19 patients) in our series. 3DP may serve as a useful adjunct to IOUS. KEY POINTS: ⢠3D printing can help in decision-making before major and complex resections in patients with liver cancer. ⢠In 5/19 patients, 3D printed model altered surgical plan preoperatively. ⢠Most surgical plan changes based on intraoperative ultrasonography were caused by detection of additional lesions not visible on CT and 3D model.
