RESUMEN
PURPOSE: Ureteroplasty using buccal or lingual mucosa graft Is feasible for complex proximal ureteral stricture (1, 2). Ileal ureter replacement is considered as the last resort for ureteral reconstruction. Totally intracorporeal robot-assisted ileal ureter replacement can be performed safely and effectively (3). In China, the KangDuo Surgical Robot 2000 Plus (KD-SR-2000 Plus) has been developed featuring two surgeon consoles and five robotic arms. This study aims to share our experience with totally intracorporeal robot-assisted bilateral ileal ureter replacement using KD-SR-2000 Plus. MATERIALS AND METHODS: A 59-year-old female patient underwent a complete intracorporeal robot-assisted bilateral ileal ureter replacement for the treatment of ureteral strictures using KD-SR-2000 Plus. The surgical procedure involved dissecting the proximal ends of the bilateral ureteral strictures, harvesting the ileal ureter, restoring intestinal continuity, and performing an anastomosis between the ileum and the ureteral end as well as the bladder. The data were prospectively collected and analyzed. RESULTS: The surgery was successfully completed with single docking without open conversion. The length of the harvested ileal ureter was 25 cm. The docking time, operation time and console time were 3.4 min., 271 min and 231 min respectively. The estimated blood loss was 50 mL. The postoperative hospitalization was 6 days. No perioperative complications occurred. CONCLUSIONS: It is technically feasible to perform totally intracorporeal robot-assisted bilateral ileal ureter replacement for the treatment of ureteral strictures using KD-SR-2000 Plus. A longer follow-up and a larger sample size are required to evaluate its safety and effectiveness.

BACKGROUND: Benign uretero-ileal anastomotic stricture (UIAS) is a potentially serious complication that can arise after radical cystectomy (RC) and subsequent urinary diversion. To preserve residual renal function and improve prognosis, it is crucial to derive insights from experience and tailor individualized treatment strategies for different patients. PATIENTS AND METHODS: From October 2014 to June 2021, a total of 47 patients with benign UIAS underwent endoscopic management (n = 19) or reimplantation surgery (n = 28). The basic data, perioperative conditions, and postoperative outcomes of the two groups were compared and analyzed to evaluate efficacy. RESULTS: Comparing preoperative and postoperative clinical efficacy within the same group, the endoscopic group showed no significant differences in creatinine and blood urea nitrogen (BUN) levels before surgery or after extubation (p > 0.05). However, significant differences were observed in glomerular filtration rate (GFR) levels on the affected side before surgery and after extubation (p < 0.05). In contrast, the laparoscopic reimplantation group did not exhibit significant differences in creatinine, BUN, or GFR levels of affected side before surgery and after extubation (p > 0.05). Postoperative clinical efficacy showed no significant difference in creatinine and BUN levels between the two groups (p > 0.05). However, GFR values of affected side in the endoscopic treatment group decreased more than those in the laparoscopic reimplantation group (p < 0.05). Additionally, the laparoscopic reimplantation group was able to remove the single-J tube earlier than the endoscopic treatment group (p < 0.05), had a lower recurrence rate of hydronephrosis after extubation (p < 0.05), and experienced a later onset of hydronephrosis compared to the endoscopic treatment group (p < 0.05). CONCLUSIONS: Based on our experience in treating UIAS following RC combined with urinary diversion, laparoscopic reimplantation effectively addresses the issue of UIAS, allowing for the removal of the ureteral stent relatively soon after surgery. This approach maintains long-term ureteral patency, preserves residual renal function, reduces the risk of ureteral restenosis and hydronephrosis, and has demonstrated superior therapeutic outcomes in this study.

BACKGROUND: Heterotopic gastric mucosa (HGM) can be located in various parts of the gastrointestinal tract. As a rare anomaly in the small intestine, it can become complicated by intussusception, obstruction, gastrointestinal bleeding, and even peritonitis, leading to death. CASE PRESENTATION: This case report focuses on a 12-year-old Middle Eastern boy who presented with hematochezia and abdominal pain for a couple of days. A tagged Red blood cell (RBC) scan and Technetium scan revealed gastrointestinal bleeding at the lower abdomen, highly suggestive of the diagnosis of Meckel's diverticulum. Subsequently, exploratory laparotomy revealed contiguous and scattered mucosal lesions with multiple polyps of various sizes in the terminal ileum. Meckel's diverticulum was absent, and the patient was treated with resection and primary anastomosis. The resected tissue revealed extensive ectopic gastric mucosa and polypoid tissues. The patient recovered uneventfully and was discharged four days after the surgery. The symptoms did not recur within six months after his surgery. CONCLUSION: Our case demonstrated that despite the rarity of multiple polypoid gastric heterotopias in the terminal ileum, it should be considered as one of the differential diagnoses of gastrointestinal tract bleeding.

BACKGROUND: Surgery for Crohn's disease (CD) is considered to have more complications due to the underlying inflammation, immunosuppression, and malnutrition. We sought to study the outcomes of right-sided colonic resection in patients with CD and patients with cancer at a high-volume tertiary center utilizing a standardized perioperative protocol. METHODS: This is a retrospective study of outcomes for all patients with CD or patients undergoing ileocolic resection or right hemicolectomy with ileocolic anastomosis at a single institution from 2013 to 2022. Patients were excluded if they simultaneously underwent another procedure or ostomy creation. Data were analyzed using Wilcoxon rank-sum and chi-squared tests for univariate analyses, and logistic and linear regressions for multivariate analyses. RESULTS: In total 141 patients with CD and 589 patients with cancer were included. Patients with CD were significantly younger with lower body mass index and less likely to have comorbidities, including diabetes and hypertension. Patients with CD were less likely to have a smoking history or prior abdominal surgery, but more likely to be on steroids. Both groups had similar rates of laparoscopy, intraoperative complications, and blood loss. Despite the preoperative and intraoperative differences, both patients with CD and patients with cancer had similar lengths of stay (LOS), readmission, reoperation, and mortality rates. None of the surgical outcomes differed significantly between the two groups. On multivariate analysis, CD diagnosis was not associated with reoperation, readmission, mortality, or LOS while controlling for other characteristics. CONCLUSIONS: With the use of standardized perioperative protocols, surgery for CD at a high-volume center with expertise in CD can be performed with comparable results to other indications like cancer.

INTRODUCTION: Penetrating Crohn's disease (CD) often necessitates surgical intervention, with the open approach traditionally favored. Robotic-assisted surgery offers potential benefits but remains understudied in this complex patient population. Additionally, the lack of standardized surgical complexity scoring in CD hinders research and comparisons. METHODS: We retrospectively analyzed adult patients with penetrating CD who underwent either robotic-assisted ileocolic resection (RICR) or open ileocolic resection (OICR) at our institution from January 2007 to December 2021. We assessed endpoints, including length of stay, complications, readmissions, reoperations, and other perioperative outcomes. RESULTS: RICR demonstrated safety outcomes comparable to OICR. Importantly, RICR patients experienced significantly reduced estimated blood loss (p < 0.0001), shorter hospital stays (median 4.5 days versus 6.9 days; p = 0.01), lower surgical site infection rates (0% versus 15.4%; p = 0.01), and decreased 30-day readmission rates (0% versus 15.4%; p = 0.01). Linear regression analysis revealed the need for additional strictureplasties (coefficient: 84.8; p = 0.008), colonic resections (coefficient: 41.7; p = 0.008), and estimated blood loss (coefficient: 0.07; p = 0.002) independently correlated with longer operative times). CONCLUSION: Robotic-assisted surgery appears to be a safe and potentially beneficial alternative for the surgical management of penetrating CD, offering advantages in perioperative outcomes reducing length of stay, blood loss, surgical site infection rates, and readmission rates. Further validation with larger cohorts is warranted.

A 9-week-old miniature Schnauzer dog was brought to a veterinary clinic because of an acute onset of vomiting. A 2 to 3-centimeter, round, firm structure in the mid-abdomen was palpated with a repeatable pain response. An exploratory laparotomy revealed a grossly cystic-appearing mass on the distal ileum. Resection and anastomosis were conducted. The histopathology report concluded the structure was an intestinal duplication, a rare congenital abnormality, with the structure sharing an outer muscular layer with the normal intestine. The resection was considered completely excised. The puppy recovered well and was clinically normal on follow-up examinations. The findings from this case suggest congenital abnormalities should always be included on a differential diagnosis list for all young animals, regardless of the presenting complaint.
Duplication intestinale chez un Schnauzer miniatureUn Schnauzer miniature âgé de 9 semaines a été présenté à une clinique vétérinaire pour cause d'apparition de vomissements aigus. Une structure ferme et ronde, de 2 à 3 cm de diamètre au milieu de l'abdomen était palpée avec une réponse à la douleur répétée. Une laparotomie exploratoire a révélé la présence d'une masse d'apparence kystique sur l'iléon distal. Une résection et une anastomose ont été effectuées. Le rapport d'histopathologie concluait que la structure était une duplication intestinale, une anomalie congénitale rare, et que la structure partageait une couche musculaire externe avec l'intestin normal. La résection a été considérée comme complètement excisée. Le chiot a bien récupéré et était cliniquement normal lors des examens de suivi. Les trouvailles dans le cas présent suggèrent que les anomalies congénitales devraient toujours être incluses dans la liste des diagnostics différentiels pour les jeunes animaux, indépendamment de la raison pour la consultation.(Traduit par Dr Serge Messier).

RATIONALE: Diffuse intestinal and mesenteric lipomatosis is a rare condition characterized by the overgrowth of adipose tissue in the intestines and mesentery. This case report aims to highlight the rare occurrence of chronic abdominal distention caused by this disease and its unique invasion into the muscle layer, which has not been previously reported. PATIENT CONCERNS: A 36-year-old woman with a 7-year history of abdominal distension was admitted to our hospital's Department of Gastrointestinal Surgery. DIAGNOSE: Abdominal and pelvic computed tomography revealed diffuse small intestinal lipomatosis. INTERVENTIONS: The patient underwent surgery. We performed an open-field ilectomy involving removal of all lipomatous intestines (250 cm). OUTCOMES: During the surgery, diffuse nodular ileal and mesenteric lipomatosis was confirmed, characterized by the presence of multiple nodular lipomas within the submucosal and muscular layers. The surgical intervention involved the resection of 250 cm of the affected ileum, followed by jejunoileal anastomosis. Postoperative pathology confirmed the diagnosis, with lesions observed in both the submucosa and muscle layers. The patient showed significant improvement in symptoms, with normal intestinal function and weight gain observed over a 10-month follow-up period, and no signs of recurrence. LESSONS: Diffuse intestinal and mesenteric lipomatosis can lead to long-term abdominal distension. Additionally, it may be involved in the muscle layer of the intestinal wall. Surgery is the primary treatment option for symptomatic intestinal lipomatosis.

Late perforation of the ileum is a rare and potentially life-threatening complication following intestinal resection. We present a unique case of a woman in her 60s with a history of appendiceal carcinoid tumour, who underwent a right hemicolectomy. Positron emission tomography and surveillance CTs showed normal surgical changes and no recurrent malignancy. Three years postoperatively, she presented with severe abdominal pain. CT revealed a perforation along the ileal wall of the ileocolonic anastomosis. She underwent emergent resection and repeat ileocolonic anastomosis. We conclude that the patient had subclinical ischaemia of the anastomosis, which eventually progressed to perforation 3 years later. We discuss a literature review on late small intestinal anastomotic perforations and their associated risk factors. Our case and literature review emphasise the importance of considering delayed anastomotic leak in postoperative patients with a history of intestinal cancer, inflammatory bowel disease, Roux-en-Y enteroenterostomy or side-to-side anastomosis.

BACKGROUND: The sleeve gastrectomy (SG) has become the most common bariatric procedure worldwide. However, insufficient weight loss or weight recidivism is frequent, which may require effective and safe revisional procedures. OBJECTIVE: To determine the technical feasibility and safety of a minimally invasive, duodeno-ileal side-to-side anastomosis using a Sutureless Neodymium Anastomosis Procedure (SNAP) for patients with weight recidivism or inadequate weight loss following SG. METHODS: This is a prospective, single-arm, open-label pilot study that enrolled patients with obesity to assist in weight reduction following an SG performed > 12 months prior. For the SNAP, self-assembling magnets were deployed into the ileum (laparoscopically) and duodenum (per-oral endoscopy). Magnets were coupled under laparoscopic and fluoroscopic guidance to create a compression anastomosis. The primary endpoints were technical feasibility, weight loss, and rate of serious adverse events (SAEs). RESULTS: Successful duodeno-ileal diversions were created with SNAP in 27 participants (mean age: 50.6 ± 9.1, mean BMI: 38.1 ± 4.6 kg/m2) with no device-related serious adverse events. Upper endoscopy at 3 months confirmed patent, healthy anastomoses in all patients. At 9 months, patients (n = 24) experienced 11.9 ± 6.2%, 14.5 ± 10.8%, and 17.0 ± 13.9% TBWL at 3, 6, and 9 months, respectively. There were no device-related SAEs. CONCLUSION: The SNAP is technically feasible and relatively safe, with all patients presenting widely patent anastomosis at 3 months. Patients experienced a progressive, clinically meaningful weight loss. Further studies are needed to confirm our findings.

INTRODUCTION: This randomized clinical trial evaluated the clinical outcomes of two surgical interventions for obesity treatment: single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI) and biliopancreatic diversion with duodenal switch (BPD/DS). The SADI procedure was developed as a response to the challenges posed by the BPD/DS procedure, aiming to enhance surgical efficiency, minimize postoperative risks, and maintain therapeutic efficacy. The present study primarily focused on early complications and short-term results. METHODS: Fifty-six patients with a body mass index (BMI) ranging from 42 to 72 kg/m2 were randomly assigned to either the SADI or BPD/DS procedure. Parameters compared included % excess weight loss (%EWL), % total weight loss (%TWL), length of hospital stay (LOS), re-admission rates, and complications. RESULTS: Both groups had similar demographics and baseline characteristics. SADI had a mean operating time of 109 min, significantly shorter than BPD/DS at 139 min (p < 0.001). Early complications occurred in five patients in the SADI group and in four patients in the BPD/DS group with no mortality. Median LOS was 2 days for both SADI and BPD/DS. Within 30 days, one SADI patient and three BPD/DS patients required re-admission. Serious late complications necessitating reoperation were observed in three SADI and two BPD/DS patients. After 1 year, %EWL and %TWL were similar: SADI (81.8% ± 13.6% and 40.1% ± 5.9%) and BPD/DS (84.2% ± 14.0% and 41.6% ± 6.4%). CONCLUSION: This trial suggests that both the SADI and BPD/DS yield comparable weight loss outcomes after 1 year, with a notable risk profile. TRIAL REGISTRATION: NCT03938571 ( http://www.

PURPOSE: The Single Anastomosis Sleeve Ileal (SASI) bypass is a novel bariatric procedure that simplifies Santoro's procedure, balancing functional restriction and neuroendocrine modulation while preserving anatomy. We aim to conduct a single-arm meta-analysis of the SASI bypass to explore its moderate-term efficacy, as this might expand the available choices for surgeons to choose the best bariatric surgery that suits the patient's condition. MATERIALS AND METHODS: We conducted a comprehensive search on PubMed, Scopus, EMBASE, and Cochrane to identify studies for the SASI bypass surgery focusing on outcomes such as %EWL, %TWL, remission rate of comorbidities, and complications. The statistical analysis was carried out using RStudio version 4.3.2. Heterogeneity was assessed using the Cochrane Q test and I2 statistics. RESULTS: Our findings illuminate SASI's potency by undertaking a single-arm meta-analysis involving 1873 patients across 26 studies. At 12 months, we report a noteworthy % Excess Weight Loss (%EWL) (Mean 84.13; 95% CI 78.41-89.85; I2 = 95%), and % Total Weight Loss (%TWL) (Mean 35.17; 95% CI 32.30-38.04; I2 = 97%), highlighting SASI's efficacy on weight loss. Cumulative meta-analyses supported these findings. More weight loss was observed with a 250 cm common limb and a greater than 3 cm anastomosis. An 88.28% remission rate in type 2 diabetes mellitus (95% CI 79.74-95.03; I2 = 84%) at 12 months was observed. Beyond weight outcomes, SASI impacts comorbidities with a good safety profile. CONCLUSION: Our study positions the SASI bypass as a good alternative option. However, long-term efficacy is yet to be explored in the future.

BACKGROUND: Retrospective research suggests that excision of the affected mesentery can improve outcomes after an ileocoecal resection in Crohn's disease. However, prospective data from randomised controlled trials are scarce. We aimed to compare rates of postoperative recurrence in patients with Crohn's disease who underwent extended mesenteric resection. METHODS: This international, randomised controlled trial was done in six hospitals and tertiary care centres in the Netherlands and Italy. Eligible patients were aged 16 years or older and had Crohn's disease that was previously confirmed by endoscopy in the terminal ileum or ileocolic region (L1 or L3 disease), with an imaging update in the past 3 months (ultrasound, MRI, or CT enterography). Eligible patients were scheduled to undergo primary ileocolic resection with ileocolic anastomosis. Enrolled patients were assigned by use of simple random allocation (1:1) to either extended mesenteric resection (intervention) or conventional mesenteric sparing resection (control). The primary endpoint was endoscopic recurrence 6 months after surgery. Analyses were done in all patients with primary endpoint data, excluding those who had no anastomosis, a postoperative diagnosis other than Crohn's disease, or withdrew consent. This trial was registered with ClinicalTrials.gov, NCT04538638. FINDINGS: Between Feb 19, 2020, and April 24, 2023, we assessed 217 patients for eligibility. 78 patients were excluded due to failure to meet the inclusion criteria or refusal to participate. 139 patients were enrolled and randomly assigned to either extended mesenteric resection (n=71) or mesenteric sparing resection (n=68). All 139 patients underwent surgery. Six patients were excluded after random assignment due to withdrawal of consent (n=2), postoperative diagnosis other than Crohn's disease (n=2) and no anastomosis performed (in case of a stoma; n=2). Two patients were lost to follow-up, and two more patients deviated from the protocol by undergoing investigations other than endoscopy 6 months after. 133 patients were included in the baseline analysis (67 in the extended resection group and 66 in the sparing resection group) of whom 57 (43%) were male. Baseline characteristics were similar between the groups, and median patient age was 36 years (IQR 25-54). 131 patients were analysed for the primary outcome. There was no difference between groups in the rate of endoscopic recurrence at 6 months after surgery (28 [42%] of 66 patients in the extended mesenteric resection group vs 28 [43%] of 65 patients in the mesenteric sparing resection group, relative risk 0·985, 95% CI 0·663-1·464; p=1·0). Five (8%) of 66 patients in the extended mesenteric resection group had anastomotic leakage within the 30 days after surgery, as did one (2%) of 65 in the mesenteric sparing group. Postoperative complications of Clavien-Dindo grade IIIa or higher were reported in seven (11%) patients in the mesenteric resection group and five (8%) in the mesenteric sparing group. INTERPRETATION: Extended mesenteric resection was not superior to conventional resection with regard to endoscopic Crohn's disease recurrence. These data support the guideline-recommended mesenteric sparing approach. FUNDING: Topconsortia voor Kennis en Innovatie-Topsector Life Sciences & Health.

BACKGROUND: There is a lack of literature on the length of the terminal ileum to be resected in right hemicolectomy for colon cancer. Therefore, we aimed to determine the mean ileal loop length and the effect of this variation on postoperative complications and long-term oncological outcomes in patients who underwent right hemicolectomy. METHODS: Right hemicolectomy surgeries performed for colon cancer in a tertiary care hospital between January 2011 and December 2018 were retrospectively analyzed from a prospective database. Two patient groups were established based on the mean length of the resected ileum above and below 7 cm. The two groups were compared for clinicopathological data, postoperative complications, mortality, long-term overall survival (OS) and disease-free survival (DFS). The factors contributing to OS and DFS were analyzed. RESULTS: The study included 217 patients. Body mass index (BMI) values were significantly higher in the ileum resection length > 7 cm group (p = 0.009). Pathological N stage, tumor diameter, and number of metastatic lymph nodes were significantly higher in the ileum resection length > 7 cm group (p = 0.001, p = 0.001, and p = 0.026, respectively). There was no significant difference for postoperative complication and mortality rates between the two groups. The mean follow-up period was 61.2 months (2-120) in all patients. The total number of deaths was 29 (11.7%) while the 60-month OS was 83.5% and 50-month DFS was 81.8%. There was no significant difference between the groups in terms of OS and DFS rates (p > 0.05). CONCLUSIONS: Excessive resection of the distal ileum in right hemicolectomy does not provide any benefit in terms of prognosis and complications.The ileum resection length and values close to it in our study appear to be sufficient.

BACKGROUND: Single Anastomosis Duodeno-Ileal bypass (SADI) is becoming a key option as a revision procedure after laparoscopic sleeve gastrectomy (LSG). However, its safety as an ambulatory procedure (length of stay < 12 h) has not been widely described. METHODS: A prospective bariatric study of 40 patients undergoing SADI robotic surgery after LSG with same day discharge (SDD), was undertaken in April 2021. Strict inclusion and exclusion criteria were applied and the enhanced recovery after bariatric surgery protocol was followed. Anesthesia and robotic procedures were standardized. Early follow-up (30 days) analyzed postoperative (PO) outcomes. RESULTS: Forty patients (37 F/3 M, mean age: 40.3yo), with a mean pre-operative BMI = 40.5 kg/m2 were operated. Median time after LSG was 54 months (21-146). Preoperative comorbidities included: hypertension (n = 3), obstructive sleep apnea (n = 2) and type 2 diabetes (n = 1). Mean total operative time was 128 min (100-180) (mean robotic time: 66 min (42-85)), including patient setup. All patients were discharged home at least 6 h after surgery. There were four minor complications (10%) and two major complications (5%) in the first 30 days postoperative (one intrabdominal abscess PO day-20 (radiological drainage and antibiotic therapy) and one peritonitis due to duodenal leak PO day-1 (treated surgically)). There were six emergency department visits (15%), readmission rate was 5% (n = 2) and reintervention rate was 2.5% (n = 1) There was no mortality and no unplanned overnight hospitalization. CONCLUSIONS: Robotic SADI can be safe for SDD, with appropriate patient selection, in a high-volume center.

PURPOSE: Kono-S anastomosis, an antimesenteric, functional, end-to-end handsewn anastomosis, was introduced in 2011. The aim of this meta-analysis is to evaluate the safety and effectivity of the Kono-S technique. METHODS: A comprehensive search of MEDLINE (PubMed), Embase (Elsevier), Scopus (Elsevier), and Cochrane Central (Ovid) from inception to August 24th, 2023, was conducted. Studies reporting outcomes of adults with Crohn's disease undergoing ileocolic resection with subsequent Kono-S anastomosis were included. PRISMA and Cochrane guidelines were used to screen, extract and synthesize data. Primary outcomes assessed were endoscopic, surgical and clinical recurrence rates, as well as complication rates. Data were pooled using random-effects models, and heterogeneity was assessed with I² statistics. ROBINS-I and ROB2 tools were used for quality assessment. RESULTS: 12 studies involving 820 patients met the eligibility criteria. A pooled mean follow-up time of 22.8 months (95% CI: 15.8, 29.9; I2 = 99.8%) was completed in 98.3% of patients. Pooled endoscopic recurrence was reported in 24.1% of patients (95% CI: 9.4, 49.3; I2 = 93.43%), pooled surgical recurrence in 3.9% of patients (95% CI: 2.2, 6.9; I2 = 25.97%), and pooled clinical recurrence in 26.8% of patients (95% CI: 14, 45.1; I2 = 84.87%). The pooled complication rate was 33.7%. The most common complications were infection (11.5%) and ileus (10.9%). Pooled anastomosis leakage rate was 2.9%. CONCLUSIONS: Despite limited and heterogenous data, patients undergoing Kono-S anastomosis had low rates of surgical recurrence and anastomotic leakage with moderate rates of endoscopic recurrence, clinical recurrence and complications rate.

INTRODUCTION: The Single Anastomosis Sleeve Ileal (SASI) bypass is a new bariatric surgery corresponding to an adaptation of the Santoro approach, consisting of a sleeve gastrectomy (SG) followed by loop gastroileostomy. Therefore, we aimed to systematically assess all the current literature on SASI bypass in terms of safety, weight loss, improvement in associated comorbidities, and complications. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta- Analyses (PRISMA) recommendations, we conducted a systematic review and meta-analysis by searching three databases (PubMed, Scopus, and Web of Science). We performed a meta-analysis of risk ratios and mean differences to compare surgical approaches for excessive weight loss, improvement/remission in type 2 diabetes mellitus (T2DM), hypertension (HT), dyslipidemia (DL), obstructive sleep apnea (OSA), and complications. Heterogeneity was assessed using the I2 statistic. RESULTS: Eighteen studies were included in the qualitative analysis and four in the quantitative analysis, comparing SASI bypass with SG and One-Anastomosis Gastric Bypass (OAGB). A comparison between Roux-en-Y Gastric Bypass (RYGB) and SASI bypass could not be performed. Compared to SG, the SASI bypass was associated with improved weight loss (MD = 11.32; 95% confidence interval (95%CI) [7.89;14.76]; p < 0.0001), and improvement or remission in T2DM (RR = 1.35; 95%CI [1.07;1.69]; p = 0.011), DL (RR = 1.41; 95%CI [1.00;1.99]; p = 0.048) and OSA (RR = 1.50; 95%CI [1.01;2.22]; p = 0.042). No statistically significant differences in any of the assessed outcomes were observed when compared with OAGB. When compared to both SG and OAGB, the complication rate of SASI was similar. CONCLUSION: Although studies with longer follow-up periods are needed, this systematic review and meta-analysis showed that SASI bypass has a significant effect on weight loss and metabolic variables. Variations in outcomes between studies reinforce the need for standardization.
