RESUMO
OBJECTIVES: Recent reports on body regional mass scalings to height have advanced understanding differences in adult heights. These studies resulted in conjectures on how regional lengths and circumferences may scale to height. We provide evidence for these conjectures by analyzing a large sample of regional limb, trunk, chest, and head lengths and circumferences in a large sample of US Army basic training recruits. METHODS: Participants consisted of 10 271 males and 2760 females ages 17 to 21 years old who reported for basic training at Fort Jackson, SC. Participants were imaged by a three-dimensional (3D) body scanner for uniform sizing which yielded 159 body measurements of total mass, lengths and circumferences at regional sites of arms, legs, trunk, chest, and head. The allometric model, Body Measur e i = α i H ß i was applied to derive scaling exponents which were applied to estimate regional mass scalings. RESULTS: Body mass scaled to height with powers of â¼2.0 (mean ß ± SE, 1.98 ± 0.04, 1.93 ± 0.06). Arm and leg lengths scaled to exponents larger than 1.0 and head height and circumferences at regional sites scaled to exponents smaller than 1.0. The leg, arm, and trunk mass scaling exponents were all above 2.0. Head mass scaled to powers smaller than 2.0. CONCLUSIONS: The 3D scanner allowed hundreds of anthropometric measurements to be obtained within seconds. The ensuing analysis revealed that greater height yielded disproportional increases in limb lengths, limb mass and trunk mass. These analyses provide evidence that could not be previously measured that further both biomechanical and metabolic conjectures.

BACKGROUND: The Roux-en-Y gastric bypass (GBP) has been considered the gold standard for many years. The loop duodenal switch (LDS) is a relatively new procedure that simplifies the complexity of the duodenal switch (BPDDS) by making it a single anastomosis procedure while at the same time giving it more intestinal absorption to reduce the rates of malnutrition associated with traditional BPDDS. This paper seeks to compare the 18-month weight loss outcomes and complications of the more standard GBP with the newer LDS in a single US center. METHODS: A retrospective matched cohort was analyzed on 108 patients who had either GBP (54 patients) or LDS (54 patients). Regression analysis was used to compare weight loss outcomes as measured by BMI and weight loss percentages. Complications gathered included bleeds, reoperations, diagnostic or therapeutic endoscopy (EGD), ulcers and chronic nausea. RESULTS: GBP and LDS have statistically similar weight loss at 18 months (39.6 vs 41 % weight loss, respectively). However, there were significantly more nausea complaints (26 vs 5), diagnostic endoscopies (EGD) (21 vs 3) and ulcers (6 vs 0) with the GBP than the LDS. CONCLUSION: LDS has comparable weight loss results to GBP. However, LDS has fewer 30-day and 18-month complications and patients suffer from less nausea postoperatively.

The chaperonin CCT mediates folding of many cytosolic proteins, including G protein ß subunits (Gßs). Here, we present a protocol for isolating Gß5 bound to CCT and its co-chaperone PhLP1 and determining the CCT-mediated folding trajectory of Gß5 using single-particle cryoelectron microscopy (cryo-EM) techniques. We describe steps for purifying CCT-Gß5-PhLP1 from human cells, stabilizing the closed CCT conformation, preparing and imaging cryo-EM specimens, and processing data to recover multiple Gß5 folding intermediates. This protocol permits visualization of protein folding by CCT. For complete details on the use and execution of this protocol, please refer to Sass et al.1.

BACKGROUND: Although the sleeve gastrectomy (SG) is the dominant bariatric procedure, studies have shown conversion rates of up to 30%. These conversions are generally for weight regain (WR), insufficient weight loss (IWL) or gastroesophageal reflux disease (GERD). Before 2020, details on why conversions were being performed were not collected in the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) Participant Use Data File (PUF). Now, the indication for sleeve conversion is noted in the PUF, allowing identification and reporting sleeve conversion reasons. OBJECTIVE: We aimed to examine the reasons for SG conversions nationwide. SETTING: The 2020 MBSAQIP PUF. METHODS: The 2020 MBSAQIP PUF was examined to determine the reasons why SG were converted to other operations. The data field of "Revision/Conversion Final Indication" was used along with "Procedure type." Primary bariatric operations were excluded. Descriptive statistics were applied. Different reasons for conversion and operations were compared by preoperative characteristics and operative outcomes. RESULTS: There were 103,782 primary SG reported in the 2020 PUF. There were 7181 SG that were converted to other operations. The most common conversion (86.2%) was to Roux-en-Y gastric bypass (RYGB). The main reason for SG conversion was GERD at 48.4%, followed by WR/IWL (41.9%). Biliopancreatic diversion with duodenal switch and single-anastomosis duodenoileal bypass with sleeve patients differed significantly from RYGB patients in specific preoperative characteristics and operative outcomes. CONCLUSION: The most common procedure SG is converted to is the RYGB. GERD was the most common reason for SG conversion, followed by WR/IWL.

A global shift is occurring as hospital procedures move to ambulatory surgical settings. Surgeons have performed outpatient sleeve gastrectomy (SG) in bariatric surgery since 2010. However, prospective trials are needed to ensure its safety before widespread adoption. PURPOSE: The study aimed to present a comprehensive report on the prospective data collection of 30-day outcomes of outpatient primary laparoscopic SG (LSG). This trial seeks to assess whether outpatient LSG is non-inferior to hospital-based surgery in selected patients who meet the outpatient surgery criteria set by the American Society for Metabolic and Bariatric Surgery. MATERIALS AND METHODS: This study is funded by the Society of American Gastrointestinal and Endoscopic Surgeons and has been approved by the Advarra Institutional Review Board (Pro00055990). Cognizant of the necessity for a prospective approach, data collection commenced after patients underwent primary LSG procedures, spanning from August 2021 to September 2022, at six medical centers across the USA. Data centralization was facilitated through ArborMetrix. Each center has its own enhanced recovery protocols, and no attempt was made to standardize the protocols. RESULTS: The analysis included 365 patients with a mean preoperative BMI of 43.7 ± 5.7 kg/m2. Rates for 30-day complications, reoperations, readmissions, emergency department visits, and urgent care visits were low: 1.6%, .5%, .2%, .2%, and 0%, respectively. Two patients (0.5%) experienced grade IIIb complications. There were no mortalities or leaks reported. CONCLUSION: The prospective cohort study suggests that same-day discharge following LSG seems safe in highly selected patients at experienced US centers.

Single-anastomosis duodenal ileostomy with sleeve gastrectomy (SADI-S) is an important emerging procedure in bariatric surgery as an alternative to performing the Roux-en-Y gastric bypass (RYGB) or the Roux-en-Y duodenal switch. With this significant weight loss and low weight regain, SADI-S has low complication rates. SADI-S, because of its anatomic configuration, also does not increase ulcer risk in patients, with almost no ulcers observed. Because of the short common channel, malnutrition is a risk. Diabetes resolution is higher than with RYGB. Overall SADI-S is a safe and effective procedure for patients with higher body mass index and patients with diabetes.

INTRODUCTION: Single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) surgery is a modification of the traditional duodenal switch (DS) surgery. SADI-S is relatively a new bariatric surgical procedure and has gone by many names depending on the length of the common channel. In this study, we report our initial experience with this novel technique in the Australian population. METHODS: The medical records of 91 patients who underwent laparoscopic primary SADI-S surgery by one surgeon at a single Australian center from January 2017 through May 2019 were retrospectively studied. RESULTS: Ninety-one patients were identified for analysis. The mean age and preoperative body mass index (BMI) was 46.2 ± 9 years and 43.2 ± 5.7 kg/m2, respectively. The mean operative time and length of stay were 121.8+/- 25 minutes and 1.4 ± 0.8 days, respectively. At 12 and 24 months, the patients lost an average BMI of 15.2 ± 5.2 kg/m2 and 17.2 ± 5.9 kg/m2, respectively. The short-term and long-term complication rates were 4.3% and 0%, respectively. The mortality rate was 0%. Postoperatively, the obstructive sleep apnea, type 2 diabetes, hyperlipidemia, hypertension, and gastroesophageal reflux disease resolution rates were 94, 94, 75, 68, and 13%, respectively. There was no statistically significant difference between most of the preoperative and postoperative nutritional data. CONCLUSIONS: SADI-S appears to be a safe bariatric surgical procedure with favorable outcomes at 2 years in the Australian population.

BACKGROUND: The sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and single-anastomosis duodenal-ileal bypass with SG (SADI-S) are recognized bariatric procedures. A comparison has never been made between these 3 procedures and especially in different body mass index (BMI) categories. OBJECTIVE: The study aimed to analyze a large cohort of patients undergoing either laparoscopic (L) SG, LRYGB, or LSADI-S to evaluate and compare weight loss and glycosylated hemoglobin level. The secondary aim was to compare the nutritional outcomes between LRYGB and LSADI-S. SETTING: Private practice, United States. METHODS: This is a retrospective review of 878 patients who underwent LSG, LRYGB, or LSADI-S from April 2014 through October 2015 by 5 surgeons in a single institution. For weight loss analysis, the patients were categorized into 4 different categories as follows: patients regardless of their preoperative BMI, patients with preoperative BMI <45 kg/m2, patients with preoperative BMI 45 to 55 kg/m2, and patients with preoperative BMI >55 kg/m2. RESULTS: A total of 878 patients were identified for analysis. Of 878 patients, 448 patients, 270 patients, and 160 patients underwent LSG, LRYGB, and LSADI-S, respectively. Overall, at 12 and 24 months, the weight loss was highest with LSADI-S, followed by LRYGB and LSG in all 4 categories. At 2 years, the patients lost 19.5, 16.1, and 11.3 BMI points after LSADI-S, LRYGB, and LSG, respectively. In addition, the weight loss was highest in patients with preoperative BMI <45 kg/m2 and lowest in patients with preoperative BMI >55 kg/m2 at 12 and 24 months. Also, there were no statistically significant differences between the nutritional outcomes between LRYGB and LSADI-S. The LSADI-S had significantly lower rates of abnormal glycosylated hemoglobin than LRYGB and LSG at 12 months (P < .001). CONCLUSIONS: The weight loss outcomes and glycosylated hemoglobin rates were better with LSADI-S than LRYGB or LSG. The nutritional outcomes between LRYGB and LSADI-S were similar.

BACKGROUND: The long-term outcomes of primary single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) have never been reported in the literature. OBJECTIVES: The study aimed to evaluate the long-term outcomes after primary laparoscopic SADI-S (LSADI-S). SETTING: Single, private institute, United States. METHODS: Data from 750 patients who underwent a primary LSADI-S from June 2013 through November 2019 by 3 surgeons were retrospectively analyzed. RESULTS: Seven hundred fifty patients were included in the study. The mean age and preoperative body mass index were 49.3 ± 13.1 years and 50 ± 12.6 kg/m2, respectively. Follow-up was available on 109 patients (61%) at 5 years and on 87 patients (53%) at 6 years. Six patients did not have any follow-up. The average operative time and length of stay were 67.6 ± 27.4 minutes and 1.5 ± .8 days, respectively. The intraoperative, short-term, and long-term complication rates were 0%, 7.8%, 11.7%, respectively. The 30-day emergency room visit, readmission, and reoperation rates were .4%, 1.1%, and 1.1%, respectively. In total, there were 15 (2%) grade IIIb long-term complications unique to LSADI-S. Complete remission of type 2 diabetes was seen in 77% of the diabetic population. At 5 and 6 years, the mean change in body mass index was 17.5 ± 6.9 and 17.6 ± 6.4 kg/m2, respectively. The mortality rate was .5%. CONCLUSIONS: LSADI-S is effective in this retrospective review in achieving good initial weight loss and weight maintenance. Although our data show acceptable nutritional complications, questions still remain because of the retrospective nature of the study.

The sleeve gastrectomy (SG) is the most popular weight loss procedure in the USA. Despite its popularity, little is definitively known about the variables that correlate with weight loss. We performed a literature search to find studies that reported variables that correlated with weight loss following SG. Forty-eight articles were identified and included. These articles covered 36 different factors predictive of weight loss while only including five predictive models. Only 12.5% of multivariate analyses evaluated sufficiently reported their results. The factors that predict weight loss following SG cannot be concluded due to the inconsistency in reporting and the methodological flaws in analysis. Reporting factors that predict weight loss should be standardized, and methods should be changed to allow physicians to use the data presented.

BACKGROUND: Laparoscopic adjustable gastric band with plication (LAGBP) is a novel bariatric procedure, which combines the adjustability of the laparoscopic adjustable gastric band (LAGB) with the restrictive nature of the vertical sleeve gastrectomy (VSG). The addition of plication of the stomach to LAGB should provide better appetite control, more effective weight loss, and greater weight loss potential. The purpose of the study was to analyze the outcomes of LAGBP at 18 months. METHODS: Data from all patients who underwent a primary LAGBP procedure from December 2011 through June 2016 were retrospectively analyzed. Data collected from each patient included age, gender, weight, body mass index (BMI), and excess weight loss (EWL). RESULTS: Sixty-six patients underwent LAGBP. The mean age and BMI were 44.6 ± 12.7 years and 42.1 ± 5.1 kg/m2, respectively. The patients lost an average of 49% and 46.8% EWL at 12 months (77.2% follow-up) and 18 months (66.1% follow-up), respectively. The mean band adjustments were 2.1 ± 1.7 (range, 0-7) per patient in 1 year. The mean additional adjustment volume (infusion and withdrawal of saline) was 0.6 ± 1 cc. Dysphagia was the most common long-term complication. The band removal rate was 7.5%. The mortality rate was 0%. CONCLUSIONS: LAGBP is a relatively safe and effective bariatric procedure. In light of recent studies demonstrating poor outcomes following LAGB, LAGBP may prove to be the future for patients desiring a bariatric procedure without resection of the stomach.

BACKGROUND: Single anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) is a modification of the biliopancreatic diversion with duodenal switch (BPD-DS) surgery. A concern with SADI-S is chronic diarrhea and hypoproteinemia. Common channel lengthening (CCL) is a surgical procedure to increase absorption in the small intestine to decrease diarrhea. OBJECTIVES: The aim of this study was to assess the occurrence and treatment of hypoproteinemia and chronic diarrhea with CCL following SADI-S surgery. SETTING: Private practice in the USA. METHODS: Patients were included if they underwent SADI-S from September 2013 to March 2018 and following surgery underwent CCL. RESULTS: Average operating time for laparoscopic CCL is 56.5 ± 4.6 min. The average bowel movements for the eight patients before laparoscopic CCL were 9.1 ± 4.7 a day. After the surgery, the bowel movements were reduced to 2.6 ± 0.4 a day. This difference was found to be statistically significantly different (p = .002). The two patients experiencing hypoproteinemia improved protein levels following CCL. CONCLUSION: CCL is an effective way to treat symptomatic chronic diarrhea after SADI-S when conservative treatments have failed.

BACKGROUND: The single-anastomosis duodenal ileostomy with sleeve gastrectomy (SADI-S) is gaining popularity in the United States as an alternative to the gastric bypass for patients with a high body mass index (BMI) or who are less likely to succeed with a sleeve. While SADI-S has similar weight loss to the gastric bypass, the complication rate is significantly lower, allowing surgeons to perform SADI-S in an ambulatory surgical center with a 23-hour stay. OBJECTIVES: To determine if SADI-S can be safely performed in an ambulatory surgical setting. SETTING: Private practice. METHODS: All SADI-S procedures performed from August 2015 to March 2019 at 2 bariatric centers were included in this study. Patients selection for SADI-S in the ambulatory surgical center required no end organ damage, no evidence of severe sleep apnea, and BMI <55 for males and BMI <60 for females. All data were gathered retrospectively from prospectively kept databases. Thirty-day complication rates were analyzed using the Clavien-Dindo scale to assess the safety of performing SADI-S in an ambulatory surgical center. RESULTS: Eighty-two patients were included in this study. The sample was 72% female with an average age of 46 and BMI of 45. All patients received planned intravenous fluid within 3 days after the procedure. There were 2 (2.4%) grade IIIb to V complications. There were no mortalities in this series. CONCLUSION: SADI-S can be performed safely in an ambulatory surgery 23-hour setting with appropriate patient selection, perioperative support, and enhanced recovery after surgery protocols.

BACKGROUND: Average percent excess weight loss data is commonly discussed preoperatively to guide patient expectations following surgery. However, there is a wide range and variation in weight loss following vertical sleeve gastrectomy (SG). Unfortunately, most surgeons and even fewer patients have heard of using predictive models to help guide their decisions on procedure choice. We have developed a predictive model for SG to help patient choice prior to this major life-changing decision. OBJECTIVE: Predict weight loss results for SG patients at 1 year using preoperative data. SETTING: Private practice. METHODS: Three hundred and seventy-one SG patients met the criteria for our study. These patients underwent surgery between October 2008 and June 2016. Non-linear regressions were performed to interpolate individual patient weights at 1 year. Multivariate analysis was used to find factors that affected weight loss. A model was constructed to predict weight loss performance. RESULTS: Variables that affect weight loss were found to be preoperative body mass index (BMI), age, hypertension, and diabetes. Diabetes and hypertension together were found to significantly affect weight loss. CONCLUSION: Patient weight loss can be accurately predicted by simple preoperative factors. These findings should be used to help patients and surgeons decide if the SG is an appropriate surgery for each patient. Using this model, most patients can avoid failure by choosing an appropriate surgical approach for their personal circumstances.

BACKGROUND: Laparoscopic adjustable gastric banded plication (LAGBP) is a procedure that has a stomach volume similar to the sleeve gastrectomy (SG). It has shown promising results but has not been adopted widely. OBJECTIVE: To determine the difference gastrectomy has on weight loss and complications. SETTING: Private practice, United States. METHODS: A retrospective, matched-cohort analysis of LAGBP and SG patients was found through matching body mass index and sex for each LAGBP to a SG patient. Body mass index, percentage excess weight loss, and total weight loss percentage were analyzed. Complication data were also collected on a short- (<30 d) and long- (>30 d) term basis. Complication rates were then compared. Data were analyzed through descriptive statistics. RESULTS: Patients who received SG lost more body mass index, percentage excess weight loss, and total weight loss percentage at 1 year and started to gain weight between 1 and 2 years. LAGBP patients weight loss also peaked at 1 year but maintained their weight loss to year 2. SG patients lost more weight at all time points, and the difference was statistically significant (P<.05). LAGBP and SG patients had statistically similar rates of short- and long-term complication rates. In the LAGBP group (57 patients) 5, 9, 13, 14, 14, and 17 patients were lost to follow-up at 3, 6, 9, 12, 18, and 24 months, respectively. In the SG group (57 patients) 11, 10, 11, 13, 20, and 29 patients were lost to follow-up at 3, 6, 9, 12, 18, and 24 months, respectively. CONCLUSION: Both procedures have peak weight loss at 1 year with acceptable complication rates. However, the SG starts to regain weight while the LAGBP shows weight stability. More time is needed to see if the weight loss curves will intersect or if the late band complications will also happen with the LAGBP as they have with band placement without plication.

BACKGROUND: Loop duodenal switch (LDS) can result in fat and starch malabsorption. In a small percentage of patients, a relevant qualitative and quantitative change in stools happens usually characterized by steatorrhea-like diarrhea. Bismuth subgallate (BS) has been marketed as a way to eliminate the odor associated with flatulence and bowel movements. The objective of this study is to see the efficacy and effect of BS on the quality of life (QOL) in patients undergoing LDS. METHODS: A prospective, randomized, double-blinded, placebo-controlled, crossover study was designed. Thirty-six patients who reported flatus and/or stool odor changes and have completed at least 6 months post-LDS were included. Patients participated in two treatment periods, each lasting for 1 week, separated by 1-week washout. Patients received 200 mg BS, 2 capsules per meal, or placebo for 1 week each. The Gastrointestinal Quality of Life Index (GIQLI) questionnaire was used to compare the QOL before the initiation of the therapy and after each treatment completion. RESULTS: Of 36 patients, 5 patients were lost to follow-up and 2 were withdrawn from the study. And 29 patients were included for final analysis. GIQLI scores obtained with BS treatment completion were significantly higher both overall (P = 0.007) and in the digestive domain (P < 0.001) than those obtained before the treatment. GIQLI scores obtained from the other domains were also higher compared to the pre-treatment as well as placebo treatment but not statistically significant. CONCLUSION: In our double-blinded trial, treatment with BS after LDS statistically improves GIQLI score and steatorrhea-like symptoms.

BACKGROUND: Inadequate weight loss, weight recidivism, and device-related complications after an adjustable gastric banding (AGB) can be treated by a laparoscopic conversion to stomach intestinal pylorus-sparing surgery (SIPS). OBJECTIVE: The aim of the study was to analyze the midterm outcomes of revision SIPS surgery after failed AGB. SETTING: Private practice, United States. METHODS: This is a retrospective review of our prospectively collected data of patients who underwent laparoscopic conversion from AGB to SIPS surgery from June 2013 and February 2017 by a single surgeon in a single institution. RESULTS: Twenty-seven patients (1 stage: 22 and 2 stage: 5) underwent a laparoscopic revision of AGB to SIPS surgery. The mean ± standard deviation preoperative body mass index (BMI) before AGB was 47.5 ± 6.8 kg/m2, while the mean nadir BMI after AGB was 36 ± 7.7 kg/m2. The overall time to reoperation was 9.3 ± 8.7 and 5.6 ± 2.5 years in 1- and 2-stage conversion patients, respectively. The mean preoperative BMI before revision SIPS surgery was 46.7 ± 7 kg/m2. At 36 months, the patients had an average change in BMI of 20.9 units with 90% excess weight loss. A major complication occurred in 4 patients. Postoperatively, the fasting blood glucose, insulin, low-density lipoprotein, triglyceride, and most of the co-morbidities were resolved or improved. CONCLUSION: This study demonstrates that conversion of failed AGB to SIPS surgery is an effective approach to AGB failure.

BACKGROUND: Single anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) is a modification of Roux-en-Y duodenal switch (RYDS). Long-term data on this operation is lacking in the literature. We reviewed our mid-term data of this RYDS modification. PURPOSE: To analyze the outcomes with SADI-S at 4 years. METHODS: Data from patients who underwent a primary SADI-S procedure performed by three surgeons at a single institution from June 2013 through February 2018 were retrospectively reviewed. All revision bariatric surgeries were excluded. Regression analyses were performed for all follow-up weight loss data. RESULTS: There were 437 patients in our database. The pre-operative mean body mass index (BMI) was 49.8 ± 8.8 kg/m2. The 30-day complication rate was 7.7%. The 30-day readmission, reoperation, and mortality rates were 1.8, 1.3, and 0.2%, respectively. The long-term complication rate was 10.9%. Seventy-nine patients were 4 years post SADI-S surgery and follow-up was possible for 44 patients (55.7%). At 4 years, patients had an average change in BMI of 18.1 ± 6 units with an excess weight loss (EWL) of 85.7 ± 27.3%. At 4 years, 97.6% patients were able to maintain HbA1c < 6% with or without the use of diabetic medication. There was a statistically significant difference between most of the pre-operative and post-operative nutritional data. CONCLUSIONS: SADI-S is a safe and effective procedure in both short- and mid-term data points. Diabetes resolution and weight loss appear similar to traditional RYDS and better than RYGB.
