RESUMO
INTRODUCTION: Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are the two most performed techniques in bariatric surgery. The aim of this study is to compare two surgical procedures in terms of weight loss and the development of comorbidities such as type II diabetes mellitus T2D, arterial hypertension, sleep apnea (OSAS), and gastroesophageal reflux disease (GERD). METHODS: Data from the German Bariatric Surgery Registry (GBSR) from 2005 to 2021 were used. 1,392 RYGB and 1,132 SG primary surgery patients were included. Minimum age 18 years; five-year follow-up data available. Tests were performed with a 5% significance level. RESULTS: Loss of follow-up 95.41% within five years. Five years after surgery, the RYGB showed significant advantages in terms of excess weight loss (%EWL 64.2% vs. 56.9%) and remission rates of the studied comorbidities: hypertension (54.4% vs. 47.8%), OSAS (64.5% vs. 50.1%), and GERD (86.1% vs. 66.9%). Compared to the pre-test, individuals diagnosed with insulin-dependent T2D showed significant improvements with RYGB over a five-year period (remission rate: 75% vs. 63%). In contrast, non-insulin-dependent T2D showed no significant difference between the two approaches (p = 0.125). CONCLUSION: Both surgical procedures resulted in significant weight loss and improved comorbidities. However, the improvement in comorbidities was significantly greater in patients who underwent RYGB than in those who underwent SG, suggesting that the RYGB technique is preferable. Nevertheless, RYGB requires a high degree of surgical skill. Therefore, acquiring expertise in the technical facets of the surgery is essential to achieving favorable outcomes.

PURPOSE: Rectosigmoid resection rectopexy has been established as an effective therapy for obstructive defecation syndrome. The addition of the NOSE-technique provides an even less invasive approach avoiding minilaparotomy, but can be technically challenging. Application of a robotic platform has been proposed to facilitate the specimen extraction and fashioning of the intracorporeal anastomosis and has been proven to be effective in left-sided colectomies. METHODS: After establishing laparoscopic rectosigmoid-resection-rectopexy with NOSE, we modified our technique by addition of the robotic platform. Whenever robotic capacity was available, elective patients scheduled for rectosigmoid resection rectopexy for obstructive defecation syndrome were operated robotically assisted. Demographic and intraoperative data were prospectively collected. Follow up was assessed using the Wexner constipation score, Wexner incontinence score, and Altomare ODS score. RESULTS: The NOSE-RRR technique was completed in all 31 patients. The mean operative time was 166 min (range 67-230). No conversion was required. The median hospital stay was 5 days (range 3-28). Four patients had minor complications (Clavien I). Two patients were reoperated (Clavien IIIb). Functional scores improved significantly postoperatively. Mean Wexner incontinence score was 7.1 preoperatively, 6.9 after 1 month, and decreased significantly to 3.93 after 3 months (p < 0.001). Mean Altomare ODS score was 17.47 preoperatively and 6.93/5.03 after 1/3 months (p < 0.001). Wexner constipation score (12.83) also showed a significant improvement after 1/3 months (6.97/6.67; p < 0.001). CONCLUSION: NOSE-RRR can be performed safely with a low rate of manageable complications. The technique provides a significant improvement for ODS-Symptoms.

PURPOSE: While obesity is prevalent among patients with type I diabetes mellitus (T1DM), the effects of metabolic surgery on patients with T1DM have not been adequately investigated. The study aims to investigate the perioperative outcomes and the improvement of comorbidity 1 year following metabolic surgery amongst this patient population. METHODS: In this study, we evaluated the effects of sleeve gastrectomy (SG) and Roux-Y gastric bypass (RYGB) on patients with T1DM and insulin resistance. RESULTS: One hundred forty-nine patients (SG n = 91 and RYGB n = 58) with obesity, T1DM, and insulin resistance were analyzed. There was no significant difference in BMI reduction and %EWL 1 year after surgery between the two groups. In the SG group, BMI reduction was 6.5 kg/m2 versus 5.9 kg/m2 in the RYGB group (p=0.406). The %EWL was 68.2 ± 25.2 in the RYGB group and 64.3 ± 21.5 in SG (p=0.332). There was also no significant difference in weight loss between the two groups (14.9 ± 5.4 kg in SG vs. 14.2 ± 7 kg in RYGB; p=0.548). In all patients, insulin requirements decreased after surgery, and in 22% of patients, insulin requirements were equivalent to those of normal-weight individuals. There was a significantly higher rate of remission of reflux in RYGB patients than in SG patients (94·44% vs 29·41; p<0.001). CONCLUSION: Patients with obesity and T1DM may benefit from metabolic surgery. Both methods produce satisfactory results in this group of patients regarding daily insulin requirements and treatment of obesity-related diseases. However, the decision of which procedure should be carried out still depends on the patient's general condition and the surgeon's technical ability.

PURPOSE: Laparoscopic rectosigmoid resection rectopexy (LRR) is the most effective treatment of obstructive defecation syndrome but is associated with a higher postoperative morbidity compared to transanal approaches. Natural orifice specimen extraction (NOSE) has been described as a promising technique to lower morbidity in colorectal cancer surgery. In this study, we analyze the technical challenges of adapting this technique to LRR and compare the perioperative results to the conventional laparoscopic technique with specimen extraction via minilaparotomy and extracorporeal anastomosis. METHODS: We retrospectively analyzed 45 patients who underwent laparoscopic rectosigmoid resection rectopexy due to obstructive defecation syndrome at our institutions. From September 2020 to July 2021, we treated 17 consecutive patients with NOSE-LRR and compared the results to a historic cohort of 28 consecutive patients treated with conventional laparoscopic rectosigmoid resection rectopexy plus minilaparotomy (LAP-LRR) for specimen extraction between January 2019 and July 2020. Assessed were patient- and disease-specific parameters, operative time, hospital and postoperative complications and subjective patient satisfaction after 6 months of follow-up. RESULTS: Both groups were comparable in terms of gender distribution, age, and comorbidities. The median operating time was similar and the perioperative morbidity was comparable in both groups. The length of stay in hospital was significantly shorter in the NOSE-LRR group (median 6 vs 8 days). CONCLUSION: NOSE-LRR can be implemented safely, performed in a comparable operating time, and is associated with a comparable rate of postoperative complications. The technique offers the a potentially fast postoperative recovery compared to the conventional laparoscopic technique.

Minimally invasive resection techniques for the treatment of various pathologies of the pancreas are potentially advantageous for the treated patients in terms of restitution time and postoperative morbidity, but are a technical challenge for the responsible surgeon. The introduction of robotic assistance in visceral surgery offers a possibility for further distribution of minimally invasive procedures in pancreatic surgery.The aim of this study was to examine the possibilities for developing robotic pancreatic surgery in Germany. The data are based on the quality reports of the hospitals for the years 2015-2019 combined with a selective literature search.The number of quality reports available decreased from 1635 to 1594 between 2015 and 2019. A median of 96 clinics performed 11-20, 56 clinics 21-50 and 15 clinics more than 50 pancreaticoduodenectomies. For distal resections, there were 35 clinics with 11-20, 14 clinics with 21-50 and two clinics with more than 50 procedures. In relation to all clinics with at least five distal resections per year, minimally invasive procedures were performed at only 29 clinics; a ratio to laparoscopic left resections of over 50% was reported in only seven clinics.According to the literature, the learning curves for robotic pancreatic distal resection and pancreaticoduodenectomy diverge. While the learning curve for robotic distal resection is completed after around 20 procedures, the learning curve for robotic pancreaticoduodenectomy has several plateaus, which are reached after around 30, 100 and 250 procedures.Due to the decentralised structure of pancreatic surgery in Germany, a nationwide introduction of robotic pancreatic surgery is unlikely. The routine use of robotic pancreaticoduodenectomy will probably be restricted to high volume centres in the foreseeable future.

BACKGROUND: Peritoneal metastasis (PM) in patients with breast (BC) and endometrial cancer (EC) is rare and treatment options are limited. Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) has demonstrated efficacy against PM from various cancers, but its efficacy in BC/EC patients is unknown. METHODS: Retrospective cohort study of patients with PM from BC/EC undergoing PIPAC with doxorubicin 1.5 mg/m2 and cisplatin 7.5 mg/m2. Data were collected within an international prospective PIPAC registry. Study outcomes were microscopic tumor regression grade (TRG), survival, adverse events (CTCAE), and quality of life (QoL). RESULTS: 150 PIPAC procedures in 44 patients (BC/EC = 28/16; mean age 58.8 ± 10.1 and 63.2 ± 10.1 years, respectively) were analyzed. The mean number of PIPACs per patient was 3 (range 0-9) and 3.5 (range 0-10), respectively. Primary/secondary non-access occurred in 4/3 of 150 (5%) procedures. PIPAC induced objective tumor regression as demonstrated by repetitive PM biopsies in 73% (32/44) of patients. Peri- and postoperative CTCAE grade 3 and 4 complications were observed in 12/150 (8%) of procedures. No grade 5 event was observed. After a median follow up of 5.7 (IQR 2.7-13.0) months, overall median survival was 19.6 (95% CI: 7.8-31.5) months (from first PIPAC). QoL indicators (general health, nausea, fatigue, constipation, pain, dyspnea, social, cognitive, emotional, and physical functioning) all improved or were maintained throughout PIPAC treatments. CONCLUSIONS: Repetitive intraperitoneal chemotherapy with PIPAC is feasible and safe in patients with PM from BC and EC. PIPAC induces significant histological regression of PM while maintaining QoL.

BACKGROUND: Common metabolic diseases, such as type 2 diabetes mellitus (T2DM), hypertension, obesity, hypercholesterolemia, and metabolic dysfunction-associated steatotic liver disease (MASLD), have become a global health burden in the last three decades. The Global Burden of Disease, Injuries, and Risk Factors Study (GBD) data enables the first insights into the trends and burdens of these metabolic diseases from 1990 to 2021, highlighting regional, temporal and differences by sex. METHODS: Global estimates of disability-adjusted life years (DALYs) and deaths from GBD 2021 were analyzed for common metabolic diseases (T2DM, hypertension, obesity, hypercholesterolemia, and MASLD). Age-standardized DALYs (mortality) per 100,000 population and annual percentage change (APC) between 1990 and 2021 were estimated for trend analyses. Estimates are reported with uncertainty intervals (UI). RESULTS: In 2021, among five common metabolic diseases, hypertension had the greatest burden (226 million [95 % UI: 190-259] DALYs), whilst T2DM (75 million [95 % UI: 63-90] DALYs) conferred much greater disability than MASLD (3.67 million [95 % UI: 2.90-4.61]). The highest absolute burden continues to be found in the most populous countries of the world, particularly India, China, and the United States, whilst the highest relative burden was mostly concentrated in Oceania Island states. The burden of these metabolic diseases has continued to increase over the past three decades but has varied in the rate of increase (1.6-fold to 3-fold increase). The burden of T2DM (0.42 % [95 % UI: 0.34-0.51]) and obesity (0.26 % [95 % UI: 0.17-0.34]) has increased at an accelerated rate, while the rate of increase for the burden of hypertension (-0.30 % [95 % UI: -0.34 to -0.25]) and hypercholesterolemia (-0.33 % [95 % UI: -0.37 to -0.30]) is slowing. There is no significant change in MASLD over time (0.05 % [95 % UI: -0.06 to 0.17]). CONCLUSION: In the 21st century, common metabolic diseases are presenting a significant global health challenge. There is a concerning surge in DALYs and mortality associated with these conditions, underscoring the necessity for a coordinated global health initiative to stem the tide of these debilitating diseases and improve population health outcomes worldwide.
RESUMO
BACKGROUND: Although there is extensive literature on the effects of sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB), debate continues regarding their long-term effects on comorbidities and weight development. Therefore, both interventions continue to be the subject of scientific studies. METHODS: Weight changes, obesity-related diseases, and perioperative events are compared after both procedures. Patient data were entered into the German Bariatric Surgery Registry (GBSR). A follow-up of three years was performed. Any P value ≤0.05 indicates a significant difference. RESULTS: Seven thousand seven hundred fifty-five patients were followed for three years (SG=3791, RYGB=3964). Excess weight loss was 61.9 in SG and 69.5 in RYGB (P<0.001). BMI reduction was not significantly different (P=0.638) between the two groups. RYGB was significantly associated with remission of non-insulin-dependent diabetes mellitus (P=0.024), insulin-dependent diabetes mellitus (P=0.002), hypertension (P<0.001), sleep apnea (P<0.001) and reflux disease (GERD) (P<0.001), and a lower incidence of bleeding requiring surgical intervention (P<0.001). The SG was associated with a lower incidence of anastomotic stenosis and ileus (P=0.006 and<0.001, respectively). CONCLUSIONS: Both SG and RYGB reduce comorbidity and weight. However, RYGB is associated with a higher %EWL and remission rate of obesity-associated diseases than SG. However, it remains to be seen whether the outcomes of the two interventions are similar after a more extended follow-up period.

PURPOSE: Sleeve gastrectomy (SG) is a common bariatric procedure that has been shown to be effective in both the short and long term, but it is not without risks, some of which necessitate revision or redo surgery (RS). MATERIALS AND METHODS: GBSR (German Bariatric Surgery Registry) data were evaluated in this multicenter analysis. Short-term results (1-year follow-up) of RS (Re-Sleeve gastrectomy, Roux-en-Y gastric bypass, RYGB, Omega-loop gastric bypass, OLGB, and duodenal switch, DS) following primary SG (n = 27939) were evaluated. RESULTS: Of PSG patients, 7.9% (n=2195) needed revision surgery. Nine hundred ninety-four patients underwent the aforementioned four surgical procedures (95 with R-SG, 665 with RYGB, 141 with OLGB, and 93 DS). Loss of follow-up within 1 year 52.44%. The most common reasons for RS were weight regain and/or a worsening of preexisting comorbidities. Regarding the operating time, R-SG was the shortest of the four procedures, and DS was the longest. In general, there were no significant advantages of one procedure over another in terms of complication incidence in these categories. However, certain complications were seen more often after R-SG and DS than with other redo procedures. There were significant differences in BMI reduction 1 year after surgery (RYGB: 5.9; DS: 10.1; OLGB: 9.1; and R-SG: 9.1; p<0.001). GERD, hypertension, and sleep apnea demonstrated statistically significant comorbidity remission. Diabetes exhibited non-significant differences. CONCLUSION: According to the findings of our study, all revision surgeries effectively resolved comorbidities, promoted weight loss, and lowered BMI. Due to the disparate outcomes obtained by various methods, this study cannot recommend a particular redo method as the gold standard. Selecting a procedure should consider the redo surgery's aims, the rationale for the revision, the patient's current state, and their medical history.

INTRODUCTION: One of the most severe side effects of sleeve gastrectomy (SG) is the development or aggravation of reflux disease. This study investigates the effect of SG on the development of reflux disease and the variables that may impact this development. In addition, trends in revision surgery, weight, and comorbidity are examined among patients with reflux disease and SG and those without reflux disease and SG. This study includes 3379 individuals without reflux disease who had primary SG and were followed for three years. The demographic characteristics, comorbidities, technical features, and complications of SG were analyzed. Data were collected by the German Bariatric Surgery Registry (GBSR). 860 (25.45%) Group A patients had reflux disease following SG (Group B: no reflux after SG; 74.55%). Patients with reflux disease had longer operating times (83.8 min vs. 77.5 min, p < 0.001) and longer postoperative hospital admissions (6 days vs. 5.5 days). In group A, the %EWL was substantially greater than in group B (64.1 vs. 61.1%). 42 patients were converted from SG to RYGB (4.88%), 2 had hiatoplasty, and 5 got Endostim. There is no significant variation in perioperative complications (p value > 0.05). The incidence of complete remission of sleep apnea was higher in group A than in group B (p = 0.013; 50% vs. 44.8%). Other comorbidities were not substantially different. Reflux illness after SG is still poorly understood, despite much research. Technical and preoperative variables may promote its development. However, these assumptions remain theoretical and are not confirmed by scientific data. The majority of patients may be successfully treated using non-invasive methods, although sometimes further surgery is necessary. Despite our results and the literature, this subject is intriguing for further research.

BACKGROUND: In comparison to conservative therapy, bariatric surgery has shown many reasonable results. The current study investigates whether Omega-loop-gastric-bypass (OAGB) or Roux-en-Y gastric-bypass (RYGB) improves weight loss, comorbidities, and perioperative complications. METHODS: The study included 28,683 patients after RYGB and OAGB. Outcome criteria were perioperative morbidity, perioperative complications, and remission of comorbidities after one year of follow-up. RESULTS: Of them 14,253 patients had completed a one-year follow-up (13,483 patients by RYGB and 770 by OAGB). BMI reduction was a significant difference in favor of OAGB (17.5±5.6 kg/m2 for OAGB vs. 15.2±5.0 for RYGB; P<0.001). The %EWL was not significantly different between the two groups (P=0.073). There was also no significant difference in perioperative complications between the two groups (overall P>5%). Significant differences in favor of OAGB were observed in remission of insulin-dependent diabetes mellitus (IDDM) (P<0.001), and sleep apnea (P=0.002). Remission of reflux was more observed in RYGB than OAGB (P<0.001). Operating time was significantly higher in RYGB than OAGB (P<0.001). CONCLUSIONS: Compared with RYGB, OAGB showed significant advantages in many respects. In particular, remission of comorbidities was significantly better after OAGB than in patients after RYGB during the one-year follow-up period. Nevertheless, many other factors such as medical history, long-term expected goals of bariatric surgery, and preexisting comorbidities should be taken into account when determining indications between the two procedures. Further studies with longer follow-up periods should be conducted to determine the efficacy of the two methods more accurately.

PURPOSE: With increasing BMI, the complexity of treating patients with obesity rises. The focus of this study is to investigate the effects of sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) on perioperative morbidity and remission of comorbidities at 3 years in patients with a BMI > 50 kg/m2. MATERIALS AND METHODS: A retrospective multicenter analysis of a prospectively maintained database was performed to enroll patients with a 3-year follow-up after SG or RYGB between 2005 and 2019 and a BMI of > 50 kg/m2 preoperatively. Patients' BMI and comorbidity status were recorded preoperatively. RESULTS: We analyzed data from 2939 patients who had at least a preoperative BMI > 50 kg/m2. A total of 1278 patients underwent RYGB surgery, and 1661 underwent SG. The distribution of sex, BMI, hypertension, reflux, and sleep apnea was significant between the two groups. Three years after surgery, the percent excess weight loss (%EWL) was 62.21% in RYGB and 55.87% in SG (p < 0.001). The change in hypertension (p < 0.001) and reflux (p < 0.001) was significantly in favor of RYGB. The change in diabetes mellitus was not significant between the two groups (p > 5%). There was a minimal difference in sleep apnea in favor of SG (p < 0.001). Mortality and overall complication rates were not significant in either group. CONCLUSION: Both procedures positively affected comorbidities, BMI, and %EWL in patients with super obesity 3 years after surgery. In some categories, RYGB was better than SG. Nevertheless, the decision between the two methods remains a matter of the surgeon's experience and the patient's general condition.

BACKGROUND: This study investigates the outcome of one-stage and two-stage Roux-Y gastric bypass (RYGB) as a revision procedure after failed adjustable gastric banding (AGB). MATERIAL AND METHODS: Data of patients who underwent a one-stage RYGB (OS-RYGB) or a two-stage RYGB (TS-RYGB) revision procedure after failing AGB between 2005 and 2019 were analyzed. Outcome criteria were perioperative complications, operating time, change in weight and BMI, and remission of comorbidities at 1-year follow-up. RESULTS: Data from 230 patients after OS-RYGB and 197 after TS-RYGB were analyzed. The total perioperative complication rates were not significantly different between the two groups (overall p > 5%). In the category of other complications, there was a significant difference between the two groups, with a lower rate in TS-RYGB than in OS-RYGB (p = 0.020). Wound infections occurred more frequently after TS-RYGB than after OS-RYGB (p = 0.015). Mean operating time differed significantly between the two groups (OS-RYGB (149.9 min) and TS-RYGB 191 min; p < 0.001). The change in hypertension was significantly higher in OS-RYGB (37.9 vs. 21.1%; p = 0.007). Other comorbidities showed no significant change within 1 year after surgery. Regarding the change in BMI, %TWL, and %EWL, there were no significant benefits for either group (p = 0.574, 0.762, and 0.378, respectively). CONCLUSION: Removing a failed AGB using the OS- or TS-RYGB is safe and feasible. The decision between OS- and TS-RYGB is still individual and depends on the patient's general condition, the desired goal of the procedure, and the personal competence of the surgeon. Further studies are needed to clarify long-term outcome and effect of both procedures.

BACKGROUND: In recent decades, an extensive collection of research has shown various benefits of bariatric surgery in the remission of obesity-related diseases and in weight loss in patients with obesity. This study investigated whether sleeve gastrectomy (SG) or adjustable gastric banding (AGB) has the best benefit in terms of perioperative risk, weight loss, and remission of comorbidities. METHODS: The German Bariatric Surgery Registry included 32,051 patients after SG and AGB. Outcome criteria were perioperative morbidity, perioperative complications, and remission of comorbidities after a one-year follow-up. RESULTS: Out of them 16,441 patients had completed one-year follow-up (2042 patients after AGB and 14,399 after SG). The %EWL was 40.8±23.4 for AGB and 62.4±22.6 for SG (P<0.001). BMI reduction was a significant difference in favor of SG (8.0±4.7 after AGB vs. 15.5±5.9 after SG; P<0.001). Significant differences in favor of SG were also found for remission of IDDM (P<0.001), NIDDM (P<0.001), hypertension (P<0.001), sleep apnea (P<0.001), and reflux disease (P<0.001). However, no significant difference was found between the two groups in terms of general intraoperative and general postoperative complications (P=0.809 and P=0.883, respectively). Specific postoperative complications were documented significantly more often after SG (3.4% in SG vs. 1% in AGB; P<0.001). CONCLUSIONS: Based on the results of our study, we can conclude that both SG and AGB can be safe surgical procedures. However, SG achieved more significant results in terms of remission of comorbidities. AGB is effective in patients without severe comorbidities and high BMI.

Bariatric surgery has expanded tremendously internationally over the past decade. In recent years, bariatric surgery has experienced a significant growth in Germany. However, the question arises as to whether this development is in line with international developments or whether there is still room for improvement that could be challenged. 63,990 primary bariatric procedures recorded in the German Bariatric Surgery Registry (GBSR) were analyzed from 2005 to April 2021. The distribution of procedures according to different variants was analyzed and presented. In the last 16 years, 17 different procedures have been performed. The most common surgical procedure was sleeve gastrectomy (SG), followed by Roux-Y gastric bypass (RYGB) (42%). Adjustable gastric banding (AGB) has declined over time, from 23.5% in the first 5 years to 0.2% in recent years. In comparison, omega-loop gastric bypass has increased over the past 5 years (from 0.4% in the first 5 years to 5.9% in the last 5 years). Laparoscopic procedures have accounted for 96.4% of all bariatric surgeries in recent years. The frequency of some procedures has decreased and some bariatric procedures have lost significance. Overall, bariatric surgery in Germany has developed positively compared to the international trend. Nevertheless, there is one area that needs to be optimized: the development of robotic bariatric surgery, which crawls behind in Germany compared to other countries. To establish the technology in bariatric surgery in a timely manner, a balance must be found between cost neutrality and patient-oriented applications.

PURPOSE: Beginning January 1, 2005, bariatric surgery cases were examined with the help of the quality assurance study for operative medicine. All data were registered and analyzed prospectively in cooperation with the Institute of Quality Assurance in Surgery at the Otto-von-Guericke University Magdeburg, Germany. The comparative study focuses on perioperative morbidity, complications, and remission of obesity-associated diseases after gastric bypass (RYGB) and sleeve gastrectomy (SG) at 5-year follow-up. MATERIALS AND METHODS: Data collection includes patients of full age who underwent SG or RYGB surgery between 2005 and 2017. The bougie is limited to 33-40 French for SG. The Roux-en-Y length for RYGB is set to 120-180 cm, and the biliodigestive length is set to 40-60 cm. Outcome criteria are perioperative morbidity, postoperative and intraoperative complications, and remission on comorbidities. RESULTS: Between 2005 and 2017, 64,349 patients were enrolled in German Bariatric Surgery Registry (GBSR). Primary operations that were performed were 56.328. Out of 24,146 RYGB and 24,085 SG procedures, 922 patients had a complete 5-year follow-up. These are 342 SG patients and 580 patients with RYGB. A matching was realized for n = 285 (83.3%) patient pairs based on age, BMI, gender, ASA, and comorbidities. A significant disadvantage was identified for the SG procedure regarding reflux disease compared with RYGB (36.3% vs. 8.10%; p < 0.001). There were no significant disadvantages in terms of BMI reduction [14.92 in the RYGB and 14.50 in the SG (p = 0.437)] and %EWL [60.32 in the RYGB and 58.98 in the SG (p = 0.504)]. This also applies to the remission of NIDDM, IDDM, hypertension, and sleep apnea; no significant differences were found. CONCLUSION: The results of the study show significant findings for gastroesophageal reflux. In terms of complications and obesity-associated diseases, no significant disadvantages between both treatments were found. RYGB and SG had comparable postoperative morbidity rates. The two surgical methods are legitimate bariatric procedures. However, there is a need for further evaluation to optimize patient selection in the coming years.

BACKGROUND: Since 1 January 2005, the practice of bariatric surgery has been examined with the help of the German Bariatric Surgery Registry (GBSR) in Germany. The focus of the study was to evaluate if sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) has the best benefit in terms of perioperative risk in patients over 60 years of age. METHODS: Data collection includes patients over the age of 60 years who underwent SG or RYGB between 2005 and 2017. The bougie is limited to 33-40 French for SG. Furthermore, the RYGB is determined to be 120-180 cm alimentary and 40-60 cm biliopancreatic length. Outcome criteria are perioperative morbidity, postoperative complications, 30-day mortality, and postoperative length of stay. RESULTS: The study analyzes data from 3561 patients beyond the age of 60 years who underwent SG (1970 patients) and RYGB (1591 patients). Mean age of the patients was 63.4 ± 3.2 in the RYGB group and 63.8 ± 3.5 in the SG group. Mean BMI was 46.4 ± 6.8 in the RYGB group and 49.1 ± 8.0 in the SG group. The average number of comorbidities was 4.5 ± 2.4 for RYGB and 4.5 ± 2.3 for SG. For the 30-day mortality, identical results were found SG vs. RYGB (0.31 vs. 0.38, p = 1.000). CONCLUSION: Based on the results of this study, it can be concluded that both SG and RYGB in patients ≥ 60 years can be considered safe surgical procedures.

Background: The practice of bariatric surgery was studied using the German Bariatric Surgery Registry (GBSR). The focus of the study was to evaluate whether revision surgery One-Step (OS) or Two-Step (TS) sleeve gastrectomy (SG) has a large benefit in terms of perioperative risk in patients after failed Adjustable Gastric Banding (AGB). Methods: The data collection includes patients who underwent One-Step SG (OS-SG) or Two-Step SG (TS-SG) as revision surgery after AGB and primary SG (P-SG) between 2005 and 2019. Outcome criteria were perioperative complications, comorbidities, 30-day mortality, and operating time. Results: The study analyzed data from 27,346 patients after P-SG, 320 after OS-SG, and 168 after TS-SG. Regarding the intraoperative complication, there was a significant difference in favor of P-SG and TS-SG compared to OS-SG (p < 0.001). The incidence of pulmonary complications was significantly higher in the OS-SG (p < 0.001). There was also a significant difference in occurrence of staple line stenosis in favor of TS-SG (p = 0.005) and the occurrence of sepsis (p = 0.008). The mean operating time was statistically longer in the TS-SG group than in the OS-SG group (p < 0.001). The 30-day mortality was not significantly different between the three groups (p = 0.727). Conclusion: In general, our study shows that converting a gastric band to a SG is safe and feasible. However, lower complications were obtained with TS-SG compared to OS-SG. Despite acceptable complication and mortality rates of both procedures, we cannot recommend any surgical method as a standard procedure. Proper patient selection is crucial to avoid possible adverse effects.
