RESUMEN
Introduction: Sleeve gastrectomy (SG) is currently the most frequently performed bariatric procedure in the world. However, the occurrence of gastroesophageal reflux disease (GERD) after SG remains controversial and questionable. Aim: To determine the occurrence of GERD after SG using a pH-monitoring study. Material and methods: This is a prospective study involving patients undergoing SG in one surgical centre. Inclusion criteria were eligibility for bariatric surgery, no symptoms of GERD, normal gastroscopy, and pH-monitoring before the surgery. Postoperative examinations were performed 6 months after surgery. Results: A total of 38 patients were analysed in the study. The mean age was 44.9 years, and the mean preoperative BMI was 42.6 kg/m2. Before surgery, all patients had normal pH values. After surgery, mean acid exposure time (AET), number of refluxes, and DeMeester score increased statistically significantly (p < 0.001). 27 (71.1%) patients each had AET > 6%, but only 9 (23.7%) reported GERD symptoms and the need for PPIs. The correlation between AET and %TWL was moderate positive, and the correlation between DeMeester score and %TWL was low positive (p = 0.011, p = 0.014, respectively). Conclusions: GERD after SG seems to be a significant problem. More than two-thirds of patients had de novo GERD after SG in pH-monitoring, but only one-quarter of them required PPIs.
RESUMEN
Introduction: In the era of an aging society and a growing number of obese people, an increasing number of older patients are consulting bariatric surgeons. The incidence of hypertension (HT) also rises with age and body weight, making the treatment of the elderly a significant challenge. Aim: To identify predictors of HT remission after bariatric surgery in patients over 65 years of age. Material and methods: A retrospective study analyzed patients over 65 years old with HT who underwent laparoscopic bariatric procedures in Poland between 2008 and 2022. The data came from 11 bariatric centers. Patients were categorized into two groups: responders (R) and non-responders (NR). A multivariate logistic regression analysis was conducted to identify significant independent risk factors. Results: The study analyzed 244 patients, with complete HT remission observed in 55 (22.5%) patients. Almost 90% of patients showed improvement in HT. The mean follow-up time was 47.4 months. Factors contributing to HT remission included HT duration of less than 5 years, the use of single medication, and a significant correlation with %EWL. Conclusions: Bariatric surgery in patients aged over 65 has a positive effect on HT remission. The chance of HT remission increases with fewer medications, shorter HT duration, and greater weight loss after surgery.
RESUMEN
Background and objectives: Gastroesophageal reflux disease (GERD) is a common disease affecting approximately 20% of the adult population. This study aimed to compare the results of laparoscopic Nissen fundoplication (LNF) in the treatment of GERD in patients of different age groups. Materials and Methods: A retrospective analysis was performed on patients who underwent LNF in one surgical department between 2014 and 2018. Patients were divided into three groups based on age: under 40 years of age, 40-65 years of age, and over 65 years of age. Results: A total of 111 patients (44.1% women) were analyzed in this study. The mean age was 50.2 ±15 years, and the mean follow-up was 50 months ± 16.6 months. Recurrence of symptoms occurred in 23%, 20%, and 23% in each age group, respectively (p = 0.13), and 85%, 89%, and 80% of patients from the respective groups reported that they would recommend the surgery to their relatives (p = 0.66). Furthermore, 83%, 92%, and 73% of patients from the respective age groups reported that they would undergo the surgery again with the knowledge they now had (p = 0.16). Conclusions: Given these results and observations, LNF has been shown to be a good method of treatment for GERD in every age group. In our study, there were no differences found in terms of satisfaction with surgery and associated recommendations between the studied age groups.

<b><br>Introduction:</b> It is already known that bariatric surgery can improve the health and quality of life of morbidly obese patients of all ages. Our population is getting older. That is why the number of bariatric surgeries among obese people over 65 years of age is systematically increasing.</br> <b><br>Aims:</b> The study aims to analyze the management of patients over 65 years of age in Polish bariatric centers.</br> <b><br>Material and methods:</b> The study was conducted on representatives from the 30 largest bariatric departments in Poland. By collecting surveys, we aimed to analyze changes in qualifications for surgery and care for elderly patients.</br> <b><br>Results:</b> 13 of 30 (43.3%) representatives responded to the survey. The remaining centers did not qualify patients over 65 years old for the surgical treatment of obesity. The mean percentage of patients over 65 who underwent bariatric surgery was 2.75. Most representatives (69.2%) chose SG as the procedure of choice in patients over 65 years of age. According to 84.6% of surgeons, age did not matter when qualifying patients over 65 years of age for BS. The majority of surgeons (53.8%) believed that bariatric surgery in older patients was comparable to the one in younger patients. Nine (69.2%) surgeons believed that there should be no age limit for bariatric surgery.</br> <b><br>Conclusions:</b> Only almost half of the bariatric centers in Poland perform operations on patients over 65 years of age.

BACKGROUND: Although bariatric surgery in patients over 65 years of age gives comparable results to treatment in the younger population, there are still controversies regarding the indications for surgery, risk assessment and choice between different types of surgery. The study aimed to identify the factors contributing to weight loss success after bariatric surgery in patients over 65 years of age. MATERIAL AND METHODS: This is a retrospective, multicenter cohort study of patients with obesity aged over 65 years undergoing primary laparoscopic bariatric surgery in the years 2008-2022. Data came from 11 bariatric centers. Patients were divided into two groups: responders (R) who achieved more than 50% EWL and non-responders (NR) who achieved less than 50% EWL. Both groups were compared. Uni- and multivariate logistic regression was used to identify predictors of weight loss success. RESULTS: Out of 274 analyzed patients, the average BMI before surgery was 42.9 kg/m2. The most common obesity-related diseases were hypertension (85.1%) and type 2 diabetes (53.3%). Sleeve gastrectomy was the most frequently performed procedure (85.4%). Uni- and multivariate logistic regression analysis confirmed preoperative BMI (OR=0.9, 95%CI:0.82-0.98, P=0.02), duration of diabetes >10 years (OR=0.3, 95%CI:0.09-0.82, P=0.02), balloon placement (OR=10.6, 95%CI: 1.33-84.83, P=0.03), time since first visit (OR=0.9, 95%CI:0.84-0.99, P=0.04), preoperative weight loss (OR=0.9, 95%CI:0.86-0.98, P=0.01) and OAGB (OR=15.7, 95%CI:1.71-143.99, P=0.02) to have a significant impact on weight loss success 1 year after bariatric surgery. CONCLUSIONS: Patients with higher preoperative weight loss may have a poorer response to surgery. OAGB emerged as the most beneficial type of surgery in terms of weight loss. Intragastric balloon placement before surgery may be effective in patients above 65 years of age and may be considered as a two-stage approach.
RESUMEN
PURPOSE: Societies are aging, life expectancy is increasing, and as a result, the percentage of elderly people in the population is constantly increasing. When qualifying patients over 65 years of age for bariatric surgery, the benefits and risks should be carefully assessed. Weighing risk factors against each other to improve the quality of life and better control of obesity-related diseases. The study aimed to determine risk factors for bariatric surgery among patients over 65 years of age. METHODS: A multicenter, retrospective analysis of patients undergoing laparoscopic bariatric procedures from 2008 to 2022. The patients were divided into two groups: complicated (C) and uncomplicated (UC). Uni- and multivariate logistic regression analysis was performed to obtain significant, independent risk factors. RESULTS: There were 20 (7.0%) patients in C group and 264 (93.0%) patients in UC group. The most common complication was intraperitoneal bleeding (8, 2.8). There was no postoperative mortality. The mean follow-up was 47.5 months. In a multivariate logistic regression analysis, length of stay and %EWL significantly corresponded to general complications (OR 1.173, OR 1.020). A higher weight loss before surgery lowered the risk for hemorrhagic events after surgery (OR 0.889). A longer length of stay corresponded to leak after surgery (OR 1.175). CONCLUSIONS: Bariatric and metabolic surgery appears to be a safe method of obesity treatment in patients over 65 years of age. The most common complication was intraperitoneal bleeding. A prolonged hospital stay may increase the risk of leakage, while a higher weight loss before the surgery may lower the risk of bleeding.

Forest soils harbor hyper-diverse microbial communities which fundamentally regulate carbon and nutrient cycling across the globe. Directly testing hypotheses on how microbiome diversity is linked to forest carbon storage has been difficult, due to a lack of paired data on microbiome diversity and in situ observations of forest carbon accumulation and storage. Here, we investigated the relationship between soil microbiomes and forest carbon across 238 forest inventory plots spanning 15 European countries. We show that the composition and diversity of fungal, but not bacterial, species is tightly coupled to both forest biotic conditions and a seven-fold variation in tree growth rates and biomass carbon stocks when controlling for the effects of dominant tree type, climate, and other environmental factors. This linkage is particularly strong for symbiotic endophytic and ectomycorrhizal fungi known to directly facilitate tree growth. Since tree growth rates in this system are closely and positively correlated with belowground soil carbon stocks, we conclude that fungal composition is a strong predictor of overall forest carbon storage across the European continent.

The increasing prevalence of bariatric surgery has resulted in a rise in the number of redo procedures as well. While redo bariatric surgery has demonstrated its effectiveness, there is still a subset of patients who may not derive any benefits from it. This poses a significant challenge for bariatric surgeons, especially when there is a lack of clear guidelines. The primary objective of this study is to evaluate the outcomes of patients who underwent Re-Redo bariatric surgery. We conducted a retrospective cohort study on a group of 799 patients who underwent redo bariatric surgery between 2010 and 2020. Among these patients, 20 individuals underwent a second elective redo bariatric surgery (Re-Redo) because of weight regain (15 patients) or insufficient weight loss, i.e. < 50% EWL (5 patients). Mean BMI before Re-Redo surgery was 38.8 ± 4.9 kg/m2. Mean age was 44.4 ± 11.5 years old. The mean %TWL before and after Re-Redo was 17.4 ± 12.4% and %EBMIL was 51.6 ± 35.9%. 13/20 patients (65%) achieved > 50% EWL. The mean final %TWL was 34.2 ± 11.1% and final %EBMIL was 72.1 ± 20.8%. The mean BMI after treatment was 31.9 ± 5.3 kg/m2. Complications occurred in 3 of 20 patients (15%), with no reported mortality or need for another surgical intervention. The mean follow-up after Re-Redo was 35.3 months. Although Re-Redo bariatric surgery is an effective treatment for obesity, it carries a significant risk of complications.

Tree mortality is an objective forest health criterion and is particularly suitable for long-term and large-scale studies of forest condition. However, it is impossible to determine actual tree mortality in Central European managed forests where trees are removed for various reasons. In this case, the only way to approximate tree mortality is to define the range in which it occurs. This can be carried out by including in the mortality calculations either dead trees that remain in the stand at the end of the assessment period or additionally trees that have been removed from the stand. We used data from the annual forest monitoring surveys in Poland from 2009 to 2022 for pine, spruce, oak and birch to perform a survival analysis in which we included all removals or sanitary cuttings either as censored or complete observations. The differences between the calculated mortality rates were significant, indicating the importance of how removals are treated in the analysis. To assess which method used for mortality calculation was more appropriate, we compared values for last recorded defoliation and severity of damage from live, dead and thinned or salvaged trees. For all species studied, significant differences were found between dead trees or trees removed by sanitation cuts and living trees or trees removed by thinning, suggesting that not only dead trees remaining in the forest, but also trees removed by sanitation cuts, should be considered when calculating mortality in managed stands. We also recommend the use of survival analysis in forest monitoring as a routine method for assessing the health of stands.
RESUMEN
Armillaria root disease affects forests around the world. It occurs in many habitats and causes losses in the infested stands. Weather conditions are important factors for growth and development of Armillaria species. Yet, the relation between occurrence of damage caused by Armillaria disease and weather variables are still poorly understood. Thus, we used generalized linear mixed models to determine the relationship between weather conditions of current and previous year (temperature, precipitation and their deviation from long-term averages, air humidity and soil temperature) and the incidence of Armillaria-induced damage in young (up to 20 years old) and older (over 20 years old) coniferous stands in selected forest districts across Poland. We used unique data, gathered over the course of 23 years (1987-2009) on tree damage incidence from Armillaria root disease and meteorological parameters from the 24-year period (1986-2009) to reflect the dynamics of damage occurrence and weather conditions. Weather parameters were better predictors of damage caused by Armillaria disease in younger stands than in older ones. The strongest predictor was soil temperature, especially that of the previous year growing season and the current year spring. We found that temperature and precipitation of different seasons in previous year had more pronounced effect on the young stand area affected by Armillaria. Each stand's age class was characterized by a different set of meteorological parameters that explained the area of disease occurrence. Moreover, forest district was included in all models and thus, was an important variable in explaining the stand area affected by Armillaria.
RESUMEN
Introduction: To achieve effective weight loss and remission of comorbidities, various surgical methods are used in the treatment of obesity. The most common procedures performed worldwide are followed by the newest ones. Aim: To present the results of the first group of patients from a high-volume bariatric centre in central Europe and to compare single anastomosis sleeve ileal (SASI) as a primary and revisional procedure. Material and methods: We retrospectively analysed patients who underwent SASI for obesity from December 2018 to June 2022 by the same team of surgeons. There were 2 groups of patients. The first group consisted of patients who underwent SASI as their first bariatric procedure (primary group - PG). The second group consisted of patients who underwent SASI after previous SG procedure due to weight regain and/or symptoms of gastroesophageal reflux disease (GERD) (revisional group - RG). Results: There were 15 patients (80% female) in the PG, and 14 patients (88% female) in the RG. In the PG, %TWL 12 and 36 months after surgery was 37.8% and 43.9% respectively. In the RG, %TWL 12 and 24 months after surgery was 13.8% and 20.9%, respectively. Most patients had complete remission of T2D and HT after surgery. In the RG, 9 (81.8%) patients had remission of GERD. The worsening of GERD was reported in 4 (40%) patients in the PG. Conclusions: SASI may be an effective and safe method of treatment of obesity. SASI may be an effective method of revisional bariatric surgery performed for GERD, but not for weight regain.
RESUMEN
INTRODUCTION: With the increase in life expectancy and a growing number of people suffering from obesity, bariatric and metabolic surgery is becoming a major concern in the elderly population. The study aimed to collect, systematize and present the available data on the surgical treatment of obesity among Polish patients over 65 years of age. MATERIAL AND METHODS: A retrospective study analysed patients over 65 years who underwent laparoscopic bariatric procedures in Poland from 2008 to 2022. The efficacy endpoints were percentage of excess weight loss (EWL%), percentage of total weight loss (%TWL), improvement in obesity-related diseases. RESULTS: The group consisted of 284 patients (173 women, 60.9%). The mean follow-up was 47.5 months. The mean BMI before surgery was 43.1 kg/m2. 146 (51.4%) patients had T2D, and 244 (85.9%) had HT. The most common procedure was sleeve gastrectomy (82.0%). The mean EWL% after surgery was 50.9%, and the mean TWL% after surgery was 20.6%. There was the statistically significant difference between AGB vs OAGB, SG vs OAGB in %EWL (p = 0.0116, p = 0.009, respectively) and RYGB vs OAGB in %TWL (p = 0.0291). After surgery, 93 patients (63.7%) had complete or partial remission of T2D, and 112 patients (45.9%) had complete or partial remission of HT. CONCLUSION: Bariatric surgery appears to be a safe and effective method of treatment of obesity in patients over 65 years of age. OAGB seems to have better results in weight loss than SG, RYGB, and AGB in older patients.

INTRODUCTION: The type 2 diabetes (T2D) improvement rate in the elderly is high after bariatric and metabolic surgery, but not all patients achieve complete remission of disease. There are some predictors for T2D remission after bariatric surgery in patients of different ages, but there are few studies describing these factors in elderly patients. The study aimed to determine predictors for diabetes remission after bariatric surgery among patients over 65 years of age. MATERIAL AND METHODS: A retrospective study analyzed patients over 65 years with T2D who underwent laparoscopic bariatric procedures in European country from 2008 to 2022. Multivariate logistic regression analysis was performed to obtain significant, independent risk factors. RESULTS: The group consisted of 146 patients divided into two groups: responders (R) and nonresponders (NR). The complete remission of T2D was achieved in 51 (34.9%) patients. There were 95 (65.1%) patients in the NR group with partial remission, improvement, or no changes in T2D. The mean follow-up was 50.0 months. In a multivariate logistic regression analysis, a T2D duration of less than 5 years was found to be a predictor to T2D remission (OR = 5.5, p = 0.002), %EWL significantly corresponded to T2D remission (OR = 1.090, p = 0009). CONCLUSION: Bariatric and metabolic surgery appears to be a good option for T2D treatment in elderly patients. A shorter duration of T2D before surgery and higher %EWL after surgery were independent predictors of T2D remission in patients over 65 years of age.

Background and Objectives: Sleeve gastrectomy (SG) is an effective surgical procedure in the treatment of obesity. However, a significant percentage of patients suffer from weight regain over long-term follow-up. The mechanisms responsible for this process are still poorly understood. The aim of the study is to evaluate the predictive effect of weight regain in the second year after SG on long-term bariatric surgery effectiveness. Methods: A retrospective cohort study was performed using the database of routinely collected information about patients undergoing SG in the Department of General, Minimally Invasive and Elderly Surgery in Olsztyn. Patients were divided into two groups according to the change in body weight between the first and second years after the surgery: weight gainers (WG) and weight maintainers (WM). Results: A study group consisting of 206 patients, with follow-up over 5 years, was included in the study. The WG group consisted of 69 patients while the WM group had 137 patients. There were no significant differences between the patient characteristics (p > 0.05). The WM group had a mean %EWL of 7.45% (SD, 15.83%) and %TWL of 3.74 (SD, 8.43). The WG group had a mean %EWL of 22.78% (SD, 17.11%) and %TWL of 11.29% (SD, 8.68). The difference between the groups was statistically significant (p < 0.05). The study showed significantly better results in WM compared to WG (p < 0.05). Conclusion: Weight regain in the second year after SG may be a good factor for long-term bariatric surgery effectiveness prognosis.

BACKGROUND: Adjustable gastric band (AGB) hadbeen the preferred treatment for morbid obesity because it is minimally invasive and reversible. But now it seems to be slowly becoming a historic procedure due to the disappointing effects. The aim of the study was to systematize and present the available data on revisional bariatric surgery (RBS) after AGB among Polish patients. METHODS: It is a multicenter, retrospective analysis of patients undergoing laparoscopic RBS after AGB in 12 Polish bariatric centers. The database included patient demographics, comorbidities and surgical outcomes. RESULTS: The group consisted of 234 patients who underwent AGB, which accounted for 29% of revisional cases recorded in the Polish Revisional Obesity Surgery Study (PROSS). 195 were women (83%), and 39 were men (17%). One hundred seventy-five patients after AGB experienced a weight regain (74.5%), 36 patients a gastric band slippage (15.0%), 14 patients had gastric band intolerance (6.0%). Types of RBS included 116 sleeve gastrectomies (SG) (49.4%), 86 Roux-en Y gastric by-passes (RYGB) (36.6%), 20 one anastomosis gastric by-passes (OAGB) (8,5%). The highest weight loss expressed as %EBMIL was observed after OAGB (63.5 ± 32.4%). CONCLUSIONS: The main indication for RBS after AGB was weight regain. SG was the most frequently chosen type of RBS after AGB. RBS after AGB leads to weight loss and improvement in type 2 diabetes and hypertension with an acceptable low risk of complications. TRIAL REGISTRATION: NCT05108532.

BACKGROUND: Women who decide to become a surgeon are afraid of motherhood. The aim of this study was to establish the opinions of patients and doctors on the professional activity of pregnant surgeons (PS). METHODS: The study was conducted on a group of respondents consisting of doctors and patients. The study was carried out using a questionnaire of 12 questions. RESULTS: 1074 doctors and 657 patients responded to the survey. Doctors, especially non-surgeons, significantly more often believed that PS should stop working in the operating theatre immediately after pregnancy confirmation. Most patients thought that operations performed by PS are normal, whereas the doctors more often considered it heroic or irresponsible. Doctors more often mentioned fear of financial stability and fear of losing their reputation as reasons for working by PS. Most respondents claimed that it made no difference whether they were operated on by PS or not. However, patients significantly more often declared their willingness to be operated on by PS. CONCLUSIONS: The study showed that female surgeons may have slight concerns about how they will be perceived by colleagues and patients. However, most respondents, patients significantly more often, believed that working during pregnancy is the natural course of things.

<b><br>Introduction:</b> The rate of revisional surgeries following sleeve gastrectomy (SG) has increased. One-anastomosis gastric bypass (OAGB) appears to have multiple advantages as a primary bariatric procedure.

The most common indication for OAGB was weight regain. The follow-up was up to 7 years, the mean time was 3.58 1.21 years. The mean preoperative body mass index (BMI) was 40.38 6.15. All patients experienced significant weight loss, reaching a BMI of 33.61 (27.28- 37.13) at the last observation.

Introduction: The constantly increasing prevalence of obesity in the population and the lengthening of life expectancy affect the appearance of the problem of pathological obesity also in the elderly. At the same time, an increase in the number of bariatric procedures (also revisional) performed in elderly patients is observed. Aim: To assess the indications for revisional bariatric procedures along with the safety and postoperative results in the group of patients over 60 years of age. Material and methods: The study was conducted in 2019-2020 among patients undergoing revisional bariatric procedures in Polish bariatric centers. The data were obtained through a multicenter, observational retrospective study. Results: Our data consist of 55 (8.1%) patients older than 60 years of age who underwent revisional bariatric procedures. Revisional procedures in the group of patients over 60 years of age had fewer postoperative complications (16.4% vs. 23.1%, p < 0.05). Remission of type II diabetes or arterial hypertension was achieved to a lesser extent in patients operated on over the age of 60 (13% and 15%, respectively) compared to patients operated on under the age of 60 (47% and 34%, respectively; p < 0.05). Conclusions: Revisional bariatric procedures in the group of patients over 60 years of age do not cause an increased risk of postoperative complications or prolonged hospital stay. The possibility of achieving remission or improvement in the treatment of comorbidities in patients operated on over 60 years of age is relatively lower compared to a younger group.
RESUMEN
PURPOSE: Laparoscopic sleeve gastrectomy (LSG) is currently the most common bariatric surgery in the world. Although it appears to be a safe treatment for obesity, it is still at risk of complications. The latest literature shows that postoperative bleeding occurs in 2-4% of cases, and up to 3% of cases requires reoperation for hemostasis. The aim of the study is to assess the effect of tranexamic acid (TXA) on hemorrhagic events and the reoperation rate in patients undergoing LSG. METHODS: The study was designed as a retrospective analysis of patients undergoing LSG. We investigate the patients 6 months before and 6 months after introducing the prophylaxis doses of TXA into our bariatric protocol (non-TXA group vs TXA group). RESULTS: Three hundred fourteen patients underwent LSG in a high-volume center from 2016 to 2017. After introducing TXA, a statistically significant reduction in the incidence of hemorrhage during surgery was observed (22.3% vs 10.8%, p = 0.006). There was a statistically significant reduction in the need for the staple line oversewing (10.2% vs 1.9%, p = 0.002). The mean operating time and the mean length of hospital stay were significantly higher in the non-TXA group than TXA group (63.1 vs 53.7 min, p < 000.1; 2.3 vs 2.1, p = 0.02). In both groups of patients, no venous thromboembolism or other complications occurred within 6 months after the surgery. CONCLUSIONS: The prophylactic doses of TXA may be useful in reducing the hemorrhagic events during LSG. It may also shorten the length of hospital stay and the operating time.

Introduction: Revisional surgery is more technically challenging and associated with increased morbidity and mortality. Nevertheless, the frequency of revisional bariatric surgery (RBS) is increasing. Therefore, investigating this group of patients appears to be currently valid. Aim: The objective of this multicenter study was to collect, systematize and present the available data on RBS after surgical treatment of morbid obesity among Polish patients. Material and methods: This multicenter study included a retrospective analysis of a prospectively maintained database. Outcomes included an analysis of the indications for RBS, the type of surgery most frequently chosen as RBS and the course of the perioperative period of treatment among patients undergoing RBS. Results: The group consisted of 799 patients (624 (78.1%) women, 175 (21.9%) men). The mean age was 38.96 ±9.72 years. Recurrence of obesity was the most common indication for RBS. The most frequently performed RBS procedures were one anastomosis gastric bypass (OAGB) - 294 (36.8%) patients, Roux-en-Y gastric bypass (RYGB) - 289 (36.17%) patients and sleeve gastrectomy (SG) - 172 (21.52%) patients. After primary surgery 63.58% of patients achieved sufficient weight loss, but after RBS only 38.87%. Complications were noted in 222 (27.78%) cases after RBS with GERD being the most common - 117 (14.64%) patients. Conclusions: RBS most often concerns patients after SG. The main indication for RBS is weight regain. OAGB and RYGB were the two most frequently chosen types of RBS. Secondary operations lead to further weight reduction. However, RBS are associated with a significant risk of complications.
