Single Anastomosis Sleeve Ileal Bypass Research Articles

The outcomes of single anastomosis sleeve jejunal bypass as a treatment for morbid obesity (Two-year follow-up).

Santoro's operation is a sleeve gastrectomy with transit bipartition. The aim of the procedure is to keep pass to the duodenum to decrease nutritional deficiency and to allow endoscopic management of obstructive jaundice. To be easier, this procedure was rapidly altered to a single anastomosis sleeve ileal bypass (SASI). In this study, we shifted the anastomosis up to the jejunum to evaluate the effect of laparoscopic single anastomosis sleeve jejunal (SASJ) bypass as a treatment for morbid obesity and related comorbidities. In addition, the effect of the SASJ procedure on nutritional deficiency was examined. In this study, 150 morbidly obese patients underwent SASJ bypass with a biliary limb length of 200-250cm. All patients were followed up at 1, 3, 6, 12, 18, and 24months. We evaluated all cases by assessing BMI, complications, nutritional status, and obesity-related comorbidities. The mean age of participants was 30.6years, and the mean body mass index (BMI) was 44.6kg/m2. Of the patients, 35 (23.2%) had type two diabetes and 47 (31.3%) were hypertensive. Postoperative bleeding occurred in two cases (1.3%). One patient developed a gastric leak (0.7%), and five patients developed biliary gastritis (3.3%). One patient (0.7%) developed a pulmonary embolism. The %EWL reached 85% in 1 year. Normalization of blood glucose occurred within 2 months after surgery in all diabetic patients. Hypertension underwent remittance in 89% of hypertensive patients. All patients were gradually weaned from four types of multivitamin regimens to only one multivitamin regimen without apparent nutritional deficiency. Laparoscopic SASJ bypass is an effective, safe, and simple procedure for treating morbid obesity and comorbid conditions with least nutritional deficiency. However, long-term studies are needed.

Single-Anastomosis Sleeve Ileal (SASI) Bypass: Hopes and Concerns after a Two-Year Follow-up.

Single-anastomosis sleeve ileal (SASI) bypass is a simplification of sleeve gastrectomy with transit bipartition. Both share a metabolic foundation through early postprandial ileal brake, and SASI bypass has the advantages of shorter operative time and less incidence of internal herniation. This study evaluates the safety and outcome of SASI bypass with 2-year follow-up. A retrospective cohort study of all patients who underwent SASI bypass in the period between June 2016 and January 2019. The primary outcome was weight loss and diabetic remission. Three hundred twenty-two patients underwent SASI bypass with a mean age of 37.4 ± 15years and a mean body mass index of 50.1 ± 7.7kg/m2. Thirteen patients (4%) had early major postoperative complications. The 1-year percentage of excess weight loss (%EWL) was 86.9 ± 9.2, and diabetic remission rate was 98.2%. The 2-year %EWL was 96.7 ± 5, and diabetic remission rate was 97.9%. Twenty-six patients had gastroesophageal reflux that improved in 21 (80.7%) patients, remained stationary in 4 (15.4%) patients, and worsened in one patient who required reversal. One patient (0.3%) had severe protein-energy malnutrition and is prepared for reversal. Technical variations had no significant impact on %EWL or diabetic remission. SASI bypass had a promising outcome in terms of 2-year %EWL, diabetic remission, and improvement of preoperative GERD. However, stationary or progressive course of GERD is a substantial possibility. Although the double-outlet for the gastric content allows duodenal access, it may be an obstacle to the standardization of postoperative care. The double-outlet is not a guarantee for absence of malnutrition.

1-Year Follow-up of Single Anastomosis Sleeve Ileal (SASI) Bypass in Morbid Obese Patients: Efficacy and Concerns.

Single anastomosis sleeve ileal (SASI) bypass is a new bariatric and metabolic procedure that has both restrictive and malabsorptive effects. This study was conducted to assess both the efficacy and safety of this procedure in a short-term follow-up. This retrospective cohort study examined weight loss- and obesity-related comorbidities and complications in patients who had undergone SASI bypass from October 2017 to March 2018 at a center of excellence for bariatric/metabolic surgery. Twenty-four patients had undergone SASI bypass due to some existing risk factors of gastric cancer or premalignant lesions in the esophagogastroduodenoscopy. The mean BMI of the patients was 44.2 (median 43.7, range 37.0-54.8) kg/m2. Six and 12months after surgery, the mean (median) excessive weight loss (EWL) was 67.8% (63.3) and 86.2% (82.9) and total weight loss (TWL) was 28.5% (27.6) and 36.46% (35.8), respectively. Most patients had complete remission in type 2 diabetes mellitus (89%), arterial hypertension (86%), dyslipidemia (100%), obstructive sleep apnea (100%), and non-alcoholic fatty liver disease (73%) during the 1year after surgery. One case of extra-luminal bleeding and one case of trocar site hernia occurred after surgery. Moreover, two patients converted to sleeve gastrectomy because of hypoalbuminemia and EWL about 1year after SASI. SASI bypass is a newly introduced investigational procedure for improving weight loss and comorbidities; however, it may result in EWL and protein malnutrition and should only be performed for select patients and by well-experienced bariatric surgeons.

COMPARATIVE STUDY OF OUTCOMES BETWEEN LAPAROSCOPIC SINGLE ANASTOMOSIS SLEEVE ILEUM BYPASS (SASI BYPASS) VERSUS LAPAROSCOPIC MINI-GASTRIC BYPASS IN MORBID OBESE PATIENTS

Background: The single anastomosis sleeve ileal (SASI) bypass is a Novel Metabolic/Bariatric Surgery operation based on mini gastric bypass operation and Santoro's operation in which a sleeve gastrectomy is followed by a side to side gastro-ileal anastomosis. Objective: To evaluate the short-term outcomes between laparoscopic single anastomosis sleeve ileal bypass and mini gastric bypass, with respect to postoperative weight loss and metabolic and nutritional effects on patients. Patients and methods: This study was done at Al-AzharUniversityHospital and Al-NharHospital. It was a prospective randomized study which compared between single anastomosis sleeve ileum bypass (SASI bypass) Versus Laparoscopic Mini-gastric Bypass, in outcome. The study included 40 patients scheduled for elective laparoscopic bariatric surgery, due to morbid obesity, divided into two groups. The first group (group A) was operated by gastric mini bypass and the second group (group B) where single anastomosis sleeve ileum bypass was done. Results: The results of the study revealed that that there was high significant difference between before and after SASI surgery as regard FBG, HbAIC, triglycerides, cholesterol, HDL and LDL. Conclusion: SASI bypass is a promising operation that offers excellent weight loss and diabetic resolution.

Sleeve gastrectomy with loop bipartition as a novel procedure for management of type 2 diabetes in obese patients

Abstract Background Amidst the current worldwide epidemic of type 2 diabetes mellitus (T2DM), the global diabetes health burden is projected to reach 522 million in 2030, with much of this increase occurring in developing countries. Aim of the work to evaluate the role of laparoscopic sleeve gastrectomy with loop bipartition (single anastomosis sleeve ileal bypass) as a bariatric and metabolic procedure in control of type 2 diabetes in obese patients. Patients and methods This prospective cohort study included 20 obese adult patients with type 2 DM recently diagnosed within last 5 years. Some of them have other associated comorbidities. They were recruited at department of surgery Ain Shams University. The follow up was obtained during the first year post-operative. Results In this study, complete remission of diabetes was achieved in 75% of the patients by the 3rd post-operative month and in 95% by the end of the study. This was beside marked weight reduction and improvement of lipid profile without causing micronutrients deficiencies during the study period. Conclusion SASI bypass can be one of the most efficient metabolic procedures and could be associated with less risks. The procedure should be considered under investigations until enough long term data are available. Thus it is worth to be explored in research aiming for more data.

Single anastomosis sleeve ileal (SASI) bypass versus sleeve gastrectomy: a case-matched multicenter study.

The present study aimed to compare the outcome of single anastomosis sleeve ileal (SASI) bypass and sleeve gastrectomy (SG) in regards weight loss, improvement in comorbidities at 12months of follow-up, and postoperative complications. This was a case-matched, multicenter analysis of the outcome of patients who underwent SG or SASI bypass. Patients who underwent SASI bypass were matched with an equal number of patients who underwent SG in terms of age, sex, BMI, and comorbidities. The main outcome measures were excess weight loss (EWL) at 6 and 12months after surgery, improvement in medical comorbidities, and complications. A total of 116 patients (97 female) of a mean age of 35.8years were included. Fifty-eight patients underwent SASI bypass and an equal number underwent SG. %EWL at 6months postoperatively was similar between the two groups. SASI bypass conferred significantly higher %EWL at 12months than SG (72.6 Vs 60.4, p < 0.0001). Improvement in type 2 diabetes mellitus (T2DM) and gastroesophageal reflux disease (GERD) after SASI bypass was better than SG (95.8% Vs 70% and 85.7% Vs 18.2%, respectively). SASI bypass required longer operation time than SG (108.7 Vs 92.8min, p < 0.0001). Complications occurred in 12 (20.7%) patients after SG and 4 (6.9%) patients after SASI bypass (p = 0.056). The %EWL at 12months after SASI bypass was significantly higher than after SG. SASI bypass conferred better improvement in T2DM and GERD than SG. Both procedures had similar weight loss at 6months postoperatively and comparable complication rates.

Laparoscopic Single Anastomosis Sleeve Ileal (SASI) Bypass for Patients With Morbid Obesity: Technical Description and Short-term Outcomes.

Morbid obesity has been recognized as a public health crisis, particularly in developed countries. Single anastomosis sleeve ileal (SASI) bypass has been introduced as a novel bariatric and metabolic procedure. The present study aimed to describe the technical steps and assess the short-term outcomes of SASI bypass in patients with super morbid obesity. Adult patients of both sexes with body mass index (BMI) ≥50 kg/m underwent SASI bypass and were followed for 12 months postoperatively. Changes in BMI, excess weight loss (EWL), and improvement in comorbidities were recorded on follow-up. Twenty patients (17 female) of the mean age of 35.4 years were included in the study. The mean preoperative BMI (53.7±5.9) showed a significant decrease at 6 months (39.9±5.2) and then at 12 months (33.6±6) postoperatively. The mean %EWL was 44.3±7.8 at 6 months and 65.2±12.6 at 12 months. All patients with diabetes mellitus, osteoarthritis, and reflux esophagitis showed resolution at 12 months after the SASI bypass. Complications were recorded in 2 patients and no mortality was reported. SASI bypass is an effective and safe bariatric procedure that confers significant loss of weight and improvement in medical comorbidities. As compared with previous studies on patients with lower BMI, patients with super morbid obesity attained lower %EWL but similar resolution of diabetes mellitus at 12 months after SASI bypass.

Evaluation of the Efficacy of Single Anastomosis Sleeve Ileal (SASI) Bypass for Patients with Morbid Obesity: a Multicenter Study.

Single anastomosis sleeve ileal (SASI) bypass is a newly introduced bariatric and metabolic procedure. The present multicenter study aimed to evaluate the efficacy of the SASI bypass in the treatment of patients with morbid obesity and the metabolic syndrome. This is a retrospective, seven-country, multicenter study on patients with morbid obesity who underwent the SASI bypass. Data regarding patients' demographics, body mass index (BMI), percentage of total weight loss (%TWL), percentage of excess weight loss (%EWL), and improvement in comorbidities at 12 months postoperatively and postoperative complications were collected. Among 605 patients who underwent the SASI, 54 were excluded and 551 (390; 70.8% female) were included. At 12 months after the SASI, a significant decrease in the BMI was observed (43.2 ± 12.5 to 31.2 ± 9.7 kg/m2; p < 0.0001). The %TWL was 27.4 ± 13.4 and the %EWL was 63.9 ± 29.5. Among the 279 patients with type 2 diabetes mellitus (T2DM), complete remission was recorded in 234 (83.9%) patients and partial improvement in 43 (15.4%) patients. Eighty-six (36.1%) patients with hypertension, 104 (65%) patients with hyperlipidemia, 37 (57.8%) patients with sleep apnea, and 70 (92.1%) patients with GERD achieved remission. Fifty-six (10.1%) complications and 2 (0.3%) mortalities were recorded. Most complications were minor. All patients had 12 months follow-up. The SASI bypass is an effective bariatric and metabolic surgery that achieved satisfactory weight loss and improvement in medical comorbidities, including T2DM, hypertension, sleep apnea, and GERD, with a low complication rate.

Single Anastomosis Sleeve Ileal Bypass: New Step in the Evolution of Bariatric Surgeries

ABSTRACTPurpose: Single anastomosis sleeve ileal bypass (SASI) procedure appears as a new metabolic and bariatric surgery based on Santoro's operation, in which a sleeve gastrectomy is followed by a side–to-side gastroileal anastomosis. The study is aimed to evaluate the short-term outcomes of laparoscopic single anastomosis sleeve ileal bypass with respect to postoperative weight loss and metabolic and nutritional effects on patients. Methods: Forty-five morbidly obese patients with a mean age of 31.2 years and a mean body mass index (BMI) of 43.2 kg/m2 underwent SASI bypass. Postoperatively, all patients were followed up at 1, 3, 6, and 12 months, and during each visit data about their BMI, obesity-related comorbidities, and nutritional status were collected. Results: One year after the surgery, mean BMI decreased to 29.1 kg/m2 and there was significant decrease in plasma level of fasting blood glucose, insulin, and low-density lipoprotein. On the other hand, there was significant increase in high-density lipoprotein plasma level, whereas hemoglobin and albumin plasma level remained normal. Six months after the surgery, calcium plasma level showed mild decrease in two cases, which was improved with multivitamin tablets. In 93% of our patients, multivitamin supplements were stopped after six months of surgery. Conclusions: Laparoscopic SASI bypass has been shown to be an effective, safe, and simple procedure for the treatment of morbid obesity and its associated metabolic consequences. Moreover, it results in minimal postoperative nutritional complications in comparison to other bariatric procedures.

Efficacy of single anastomosis sleeve ileal (SASI) bypass for type-2 diabetic morbid obese patients: Gastric bipartition, a novel metabolic surgery procedure: A retrospective cohort study

IntroductionThe single anastomosis sleeve ileal (SASI) bypass is a Novel Metabolic/Bariatric Surgery operation based on mini gastric bypass operation and Santoro's operation in which a sleeve gastrectomy is followed by a side to side gastro-ileal anastomosis. The purpose of this Study is to report the clinical results of the outcomes of SASI bypass as a therapeutic option for obese T2DM patients. MethodsWe conducted a retrospective cohort study of type 2 diabetic obese patients who underwent SASI bypass at one hospital from March 1, 2013 to December 31, 2014. Patients with previous bariatric surgery, history of upper laparotomy, and with less than one year follow up, were excluded. Sleeve gastrectomy was performed over a 36-Fr bougie, 6 cm from the pylorus, and 250 cm from the ileocecal valve the ileum brought to be anastomosis side to side with the antrum. Data collected included comorbidity resolution, percent excess weight loss (% EWL), and one-year morbidity and mortality. ResultsDuring the study period, 61 underwent laparoscopic SASI bypass. Ultimately, 50 patients with a mean BMI of 48.7 ± 7.6 kg/m2 met inclusion criteria and were evaluated. %EWL reached 90% at one year and all patients have normal glucose level in the first 3 months after surgery. Hypertension remitted in 86%, hypercholesterolemia in 100% and hypertriglyceridemia in 97% of patients. There were 6 postoperative complications. One pulmonary embolism, one postoperative bleeding, one leak from biliary limb and one complete obstruction at the gastro-ileal anastomosis. Six months postoperative, one patient was diagnosed with marginal ulcer, 12 months after surgery, another patient was re-operated for fear of more excessive weight loss. ConclusionSASI bypass is a promising operation that offers excellent weight loss and diabetic resolution.
