[PMID: 38489739 PMCID: PMC10939676 DOI: 10.1097/md.0000000000037489] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 02/08/2024] [Accepted: 02/13/2024] [Indexed: 03/17/2024] Open
Abstract
Gastric cancer (GC) is one of the most common malignant tumors worldwide and the fourth leading cause of cancer-related deaths, with a relatively high incidence among the elderly population. Surgical resection is the mainstay treatment for GC and is currently the only cure. However, the incidence of postoperative intraabdominal infections remains high and seriously affects the prognosis. This study aimed to explore the risk factors for intraabdominal infections after radical gastrectomy in elderly patients and to establish and validate a risk prediction model. We collected the clinical data of 322 GC patients, who underwent radical gastrectomy at the General Surgery Department of China Medical University Dandong Central Hospital from January 2016 to January 2023. The patients were divided into an infected group (n = 27) and a noninfected group (n = 295) according to whether intraabdominal infections occurred postoperatively. A nomogram risk prediction model for the occurrence of postoperative intraabdominal infections was developed. All patients were randomized into a training set (n = 225) and a validation set (n = 97) in a 7:3 ratio, and the model was internally validated. Of the 322 patients, 27 (8.3%) experienced postoperative intraabdominal infections. Single-factor analysis revealed associations of intraabdominal infection with body mass index, glucose, hemoglobin, albumin, and other factors. The multifactorial analysis confirmed that body mass index, glucose, hemoglobin, albumin, surgical duration, and bleeding volume were independent risk factors for intraabdominal infections. The nomogram constructed based on these factors demonstrated excellent performance in both the training and validation sets. A nomogram model was developed and validated to predict the risk of intraabdominal infection after radical gastrectomy. The model has a good predictive performance, which could help clinicians prevent the occurrence of intraabdominal infections after radical gastrectomy in elderly patients.

Abstract
Bleeding and leaks are the most ominous postoperative complications after laparoscopic sleeve gastrectomy (LSG). Various staple line reinforcement (SLR) techniques have been innovated such as oversewing/suturing (OS/S), omentopexy/gastropexy, buttressing, and gluing. Currently, no high-quality evidence supports the use of one method over the others or even supports the use of SLR over no SLR. This study aimed to compare postoperative outcomes between LSG with OS/S versus LSG without any SLR.

Abstract
Leaks and bleeding are major acute postoperative complications following laparoscopic sleeve gastrectomy (LSG). Various staple line reinforcement (SLR) methods have been invented such as oversewing/suturing (OS/S), omentopexy/gastropexy (OP/GP), gluing, and buttressing. However, many surgeons do not use any type of reinforcement. On the other hand, surgeons who use a reinforcement method are often confused of what kind of reinforcement they should use. No robust and high-quality data supports the use of one reinforcement over the other or even supports the use of reinforcement over no-reinforcement. Therefore, SLR is a controversial topic that is worth our focus. The aim of this study is to compare the outcomes of LSG with versus without Seamguard buttressing of the staple line during LSG.

Outcomes of laparoscopic revisional conversion of sleeve gastrectomy to Roux-en-Y gastric bypass: Diff erent strategies for obese and non-obese Asian patients. Asian J Surg 2023; 46:761-766. [PMID: 35843822 DOI: 10.1016/j.asjsur.2022.07.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2021] [Revised: 05/05/2022] [Accepted: 07/06/2022] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Sleeve gastrectomy (SG) is the most performed bariatric procedure now. Some patients would necessitate a revision to Roux-en-Y gastric bypass (RYGB) as a salvage procedure for intractable gastroesophageal reflux disease (GERD). However, outcome of the revision in Asians with co-existed obesity and those non-obese is not clear. METHODS We retrospectively reviewed the data of patients who underwent revisional laparoscopic RYGB after SG between 2007 and 2019 for intractable GERD with data of one year follow-up. Pre-operative clinical data, perioperative outcomes, GERD symptoms, weight loss and medication details were analyzed. Patients were classified into those with body mass index (BMI) ≥ 25 and < 25 kg/m2. RESULTS Fifty-five patients (44 women, 11 men; mean age 42.5 years) were included. Mean interval from the initial SG to revision surgery was 51.2 months (range, 5-132). Mean body mass index before SG was 34.6 kg/m2, whereas that before revision surgery was 27.6 kg/m2. All the patients required continue proton pump inhibitor (PPI) to control the GERD symptoms before surgery. Among them, 36 (65.4%) patients in the obese group received long BP limb (>100 cm) RYGB for associated obesity but the common channel was assured to ≥ 400 cm or 70% of small bowel length, the other 19 (34.6%) patients in the non-obese group received standard BP limb (<100 cm) RYGB. There was no difference in basic characters between the two groups before revision surgery except a higher mean BMI (30.0 vs. 22.2 kg/m2, p < 0.001), blood pressure and triglyceride in obese group. One year after revision surgery, all the patients had improved GERD symptoms but only 33 (60%) can completely wave PPI, without difference between the 2 groups. Obese group with a long BP limb RYGB had a significant higher % total weight loss (TWL) than non-obese group (%TWL 9.1% vs. -3.1%, p = 0.005). CONCLUSION Laparoscopic revision to RYGB is a safe and effective treatment for patients with intractable GERD after SG but some patients may still have residual GERD symptoms. Using a modified RYGB technique in revision surgery may help in weight reduction for obese Asian patients.

Long-Term Efficacy of Bariatric Surgery for the Treatment of Super-Obesity: Comparison of SG, RYGB, and OAGB. Obes Surg 2021; 31:3391-3399. [PMID: 33993423 DOI: 10.1007/s11695-021-05464-0] [Citation(s) in RCA: 32] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Revised: 05/05/2021] [Accepted: 05/05/2021] [Indexed: 12/25/2022]
Abstract
BACKGROUND The most appropriate procedure for the treatment of super obesity (BMI > 50 kg/m2) is unknown. We aimed to evaluate the safety, long-term (> 5 years) weight loss, and adverse events between three commonly performed procedures, sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and one anastomosis gastric bypass (OAGB) in super-obese patients. METHODS Between January 2002 and December 2015, 498 successive patients with super morbid obesity (BMI > 50), who underwent SG or RYGB or OAGB, were recruited. Surgical outcome, weight loss, resolution of co-morbidities, and late complications were followed and compared between the 3 groups. All data derived from a prospective bariatric database and a retrospective analysis was conducted. RESULTS The average patient age was 32.1 ± 10.4 years, with a mean body mass index (BMI) of 56.0 ± 6.7 kg/m2. Of them, 190 (38.9%) underwent SG, 62 (12.4%) RYGB, and 246 (49.4%) OAGB. There was no difference in basic characters between the 3 groups except SG had fewer diabetic patients. RYGB group had higher intraoperative blood loss, longer operating time, and hospital stay than the other 2 groups. RYGB had a higher 30-days post-operative major complication rate (4.8%) than SG (0.5%) and OAGB (0.8%). The follow-up rate at 1 and 5 years was 89.4% and 52.0%. At post-operative 5 years, OAGB had a higher total weight loss (40.8%) than SG (35.1%), but not RYGB (37.2%). SG had a lower remission rate in dyslipidemia comparing to OAGB and RYGB, but T2DM remission rate was no different between the groups. The overall revision rate is 5.4% (27/498) of the whole group, and SG had a lower revision rate (2.6%) than RYGB (8.1%) and OAGB (6.9%). CONCLUSION SG is an effective and durable primary bariatric procedure for the treatment of super obesity and metabolic disorders. OAGB had a similar operation risk to SG but resulted in a better weight loss than SG.

Abstract
BACKGROUND The benefits of oversewing the staple lines during laparoscopic sleeve gastrectomy have been controversial. No study examined the benefit of oversewing the staple lines in robotic sleeve gastrectomy (RSG). This retrospective study aims to examine the difference in immediate postoperative complications, readmissions, reoperations, and emergency room visits between RSG patients with and without oversewn staple lines at a single, large-volume, bariatric center. METHODS A retrospective chart review was conducted on 623 patients who underwent RSG between November 1, 2017, and November 1, 2019. Of these, 316 had their staple line oversewn between November 1, 2017, and November 12, 2018, and 307 did not have their staple line oversewn between November 13, 2018, and November 1, 2019. RESULTS A total of 623 patients underwent RSG, of which 50.7% (n = 316) had their staple line oversewn. The mean length of hospital stay was similar between the two groups. However, the mean operative time was significantly longer in the "oversew" group than "no oversew" group by 7.4 minutes (p < 0.001). Readmission, reoperation, and intervention rates during the 30-day postoperative period were similar between the two groups. However, the percentage of patients requiring outpatient emergency room visits during the 30 days after RSG was significantly higher in the "oversew" group than that of the "no oversew" group. CONCLUSIONS No significant difference in major complications was found between RSG patients with and without oversewn staple lines. Oversewing of the staple line may be associated with increased emergency room visits.

Abstract
BACKGROUND Laparoscopic 1- (single-) anastomosis gastric bypass (OAGB) was developed as a simplified technique of Roux-en-Y gastric bypass (RYGB), but super long-term data are lacking. OBJECTIVES To evaluate the risks and long-term results of OAGB over a period of 20 years. SETTING Tertiary teaching hospital. METHODS A total of 2223 patients underwent OAGB from 2001 to 2020; the mean age was 35.3 ± 11.4 years (range, 14-71 yr), 70.2% were female, and the mean body mass index was 40.2 ± 11.9 kg/m2. All data were kept in a prospective bariatric database. Patients were divided into 4 groups, based on the 5-year period in which their surgery was performed, and a retrospective analysis was conducted. RESULTS The means for operating time, intraoperative blood loss, and length of hospital stay after OAGB were 131.9 ± 40.1 minutes, 38.5 ± 30.7 mL, and 4.5 ± 4.0 days, respectively. There were 27 patients (1.2%) with 30-day postoperative major complications overall, but the group rate decreased to .4% in the last 5-year period. At postoperative years 5, 10, and 15, the percentages of total weight loss were 31.9%, 29.6%, and 29.5%, respectively, and the percentages of excess weight loss were 77.2%, 68.4%, and 65.5%, respectively. Among 739 patients (33.2%) with type 2 diabetes (T2D), the rates of complete remission (glycated hemoglobin < 60%) at 5, 10, and 15 years were 67.3%, 73.8%, and 66.7%, respectively. The weight loss and antimetabolic effects were similar in each 5-year period, but a significant malnutrition effect was observed. A total of 113 (5.1%) patients needed revision surgery at follow-up, due to malnutrition (n = 51), weight regain (n = 24), acid or bile reflux (n = 22), marginal ulcer (n = 8), ileus (n = 3), and other causes (n = 5). At 15 years, the overall revision rate was 11.9% (27/226), and 80% of the patients were very satisfied with their procedures. CONCLUSION Our results showed that OAGB is a safe and durable primary bariatric procedure, with sustained weight loss and a high resolution of T2D up to 20 years post surgery in Taiwan, although malnutrition is a major side effect.

Abstract
OBJECTIVE To determine the influence of stapling on leakage pressures after canine partial gastrectomy. STUDY DESIGN Ex vivo study. SAMPLE POPULATION Gastric specimens from 24 adult canine cadavers. METHODS Partial gastrectomy constructs were assigned to one of three closure techniques (n = 8 per group): group 1, stapled closure with a 90-mm thoracoabdominal stapling device and a 4.8-mm staple cartridge; group 2, hand-sewn double-layer inverting suture closure with 3-0 glycomer 631; and group 3, staple line reinforcement with an inverting Cushing suture pattern. Leakage and pressure testing were performed. Initial leakage pressure (ILP), maximal leakage pressure (MLP), and leakage location were recorded. Significance was set at P < .05. RESULTS Placement of a Cushing suture (group 3) increased ILP and MLP by 3.2-fold and 2.8-fold, respectively, compared with stapled closures alone (P < .001). Constructs closed with double-layer suture closure reached ILP and MLP 4.5-fold and threefold greater, respectively, compared with those with stapled closures alone (P < .001). Maximal leakage pressure did not differ between groups 2 and 3 (P = .14). Leakage occurred from the inverting suture line in all constructs of groups 2 and 3 and from staple holes in six of eight group 1 constructs. CONCLUSION Double-layer suture closure of canine partial gastrectomies achieved superior biomechanical properties compared with stapled closure techniques. Reinforcing staple closures with an inverting suture line improved resistance to leakage. CLINICAL SIGNIFICANCE Reinforcing single-layer closure of partial gastrectomies with an inverting Cushing pattern is recommended to improve resistance to leakage. In vivo investigation is warranted to evaluate influence of closure technique on gastric healing, postoperative stasis, ischemic injury, and postoperative dehiscence.

Abstract
BACKGROUND Very few studies have explored the changes of serum pepsinogen after bariatric surgery and no research has evaluated the feasibility of ABC classification to predict gastric cancer risk after bariatric surgery. METHODS We enrolled 94 obese subjects that received bariatric surgery, including 41 sleeve gastrectomy (SG) and 53 Roux-en-Y gastric bypass (RYGB). The serum pepsinogen I (PGI), pepsinogen II (PGII), PGI/II ratio and seropositivity of Helicobacter pylori ( H. pylori ) were measured before and one year after surgery. Patients were classified according to ABC classification and post-operative change was evaluated. RESULTS Preoperatively, four (4.2%) patients were classified into high risk group (classification C and D) for gastric cancer. Significant reduction of PGI, PGII and decrease of PGI/II ratio were noted after bariatric surgery. H. pylori seropositive patients had a greater postoperative change of PGI (-38.6μg/L vs -22.1μg/L, p=0.003) and PGII (-8.0μg/L vs -2.5μg/L, p <0.001) but a less postoperative change of PGI/II ratio (-0.6 vs -2.1, p =0.04) than H. pylori seronegative patients. One year after surgery, the portion of high risk group of ABC classification for gastric cancer increased markedly from 4.2% to 23.7%. CONCLUSION Both of SG and RYGB resulted in significant reduction of serum PGI and PGII after bariatric surgery, and significantly influenced the ABC classification. The application of ABC classification for gastric cancer screening was limited after bariatric surgery.

Abstract
PURPOSE Small bowel length is drawing attention in the development of gastrointestinal bariatric/metabolic surgery, but the importance of the length of the small bowel in bariatric/metabolic is not clear. The present study was conducted to investigate variations in small bowel length and their clinical significance in patients undergoing laparoscopic sleeve gastrectomy (LSG). MATERIALS AND METHODS Small bowel length was measured in 620 patients diagnosed with obesity who underwent LSG between March 2014 and August 2018. Prospectively obtained demographic and clinical data were investigated, focusing on the association between small bowel length and weight loss. RESULTS Small bowel length varied widely among patients (mean 739.8 + 115.7 cm, range 380-1050 cm). Linear regression analysis revealed a significant association between small bowel length and body height, body weight, waist circumference, and serum levels of low-density lipoprotein cholesterol, hemoglobin, C-peptide, glycated hemoglobin (A1C), and gamma-glutamyl transferase (r-GT). Multivariate analysis confirmed that body height and serum A1C% levels independently predicted small bowel length in bariatric patients, strongly with body height (p < 0.001) but weakly with A1C%(p = 0.021). One-year follow-up rate was 75.3% (467/620), and small bowel length did not influence weight loss or the reduction of obesity related cardiovascular risk factors after LSG. CONCLUSION In this study, small bowel length varied widely among bariatric patients and was strongly associated with body height and weakly with serum A1C levels. Small bowel length has no significant role in weight loss or the resolution of cardiovascular risk factors after LSG.

Abstract
Sleeve gastrectomy is a surgical technique and a leading method in metabolic surgery. Sleeve gastrectomy gained ever-increasing popularity among laparoscopic surgeons involved in bariatric surgery and has proved to be a successful method in achieving considerable weight loss in a short time. There are some disparate effects that patients may experience after sleeve gastrectomy including a reduction in BMI, weight, blood pressure, stroke, and cancer and also a significant remission in obesity-related diseases including type 2 diabetes (T2D), Non-alcoholic fatty liver (NAFLD), cardiovascular disease, obstructive sleep apnea, and craniopharyngioma-related hypothalamic obesity as well as non-obesity-related diseases such as gout, musculoskeletal problems, ovarian disorders and urinary incontinence. The most common complications of sleeve gastrectomy are bleeding, nutrient deficiencies, and leakage. There are several studies on the impact of gender and ethnic disparities on post-operative complications. This study collects state of the art of reports on sleeve gastrectomy. The aim of this study was to analyze recent studies and review the advantages and disadvantages of sleeve gastrectomy.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) has been validated as a safe and effective treatment for morbid obesity. However, data of the long-term outcome remains lacking. METHODS A total of 1759 LSG was performed as primary bariatric procedure from 2005 to 2017 with mean age of 35.2 ± 10.3 years old (14-71), female 69.7%, mean body mass index (BMI) 37.9 ± 7.7 kg/m2, and mean waist width 113.7 ± 17.9 cm. All patients were evaluated and managed under a strict multidisciplinary team approach. A retrospective analysis of a prospective bariatric database and telephone interview of patients who defaulted clinic follow-up at 10 years was conducted. RESULTS The mean operating time, intraoperative blood, and hospital stay of LSG were 121.5 ± 36.5 min, 40.8 ± 69.7 ml, and 2.8 ± 2.7 days, respectively. The 30-day postoperative major complication occurred in 25 (1.4%) patients. The major complication rate was 15% at first year and 0% at the last year. The follow-up rate at 1, 5 and 10 years were 89.3%, 52.1 and 64.4%. At postoperative 1, 5, and 10 years, the mean percentage of total weight loss (%TWL) and excess weight loss (EWL%) of LSG patients were 33.4, 28.3, and 26.6% and 92.2, 80.1, and 70.5%, respectively. The mean BMI became 27, 26.2, and 27.1 kg/m2 at postoperative 1, 5, and 10 years. At follow-up, a total 69 patients needed surgical revision due to reflux disease (n = 45), weight regain (n = 19), persistent diabetes (n = 2), and chronic fistula (n = 3). The type of revision procedures were hiatal repair and gastropexy (n = 29), Roux-en Y gastric bypass (RYGB) (n = 23), and single anastomosis bypass (n = 17) with median time to revision 33 months (range 3-62). At 10 years, the overall revision rate was 21.5% (14/65) and 11(16.9%) of 65 patients were converted to RYGB. The other 54 patients remained at LSG anatomy, but 45% of them required proton pump inhibitor for reflux symptoms. CONCLUSIONS Our results showed that primary LSG is a durable primary bariatric procedure with sustained weight loss and a high resolution of comorbidities at 10 years, but about half the patients had de novo GERD. The need for conversion to RYGB was 16.9% at 10 years.

Abstract
BACKGROUND Bariatric surgery, especially the gastric bypass procedure, is an effective therapy for morbid obesity, but may reduce protein absorption and induce protein deficiency (PD). A recent study reported an issue about common limb length for PD. OBJECTIVE This study aimed to examine the prevalence of PD after gastric bypass surgery and investigate the role of common limb length in PD-related revision surgery. SETTING Hospital-based bariatric center. METHODS From 2001 to 2016, 2397 patients with morbid obesity who underwent bariatric/metabolic surgery with 1-year follow-up were recruited. Serum albumin and total protein were measured before and 1 year after surgery. Medical records of patients who underwent revision surgery due to PD were reviewed. RESULTS The overall prevalence of PD was .5% preoperatively. The prevalence of PD increased to 2.0% at 1 year after surgery. The incidence was highest in one-anastomosis gastric bypass (2.8%) followed by Roux-en-Y gastric bypass (1.8%). Until the end of follow-up, all 19 patients who underwent revision surgery for intractable PD had a relatively short common limb length of <400 cm. After elongation of the common limb length to >400 cm in revision surgery, PD improved in all patients. CONCLUSIONS A subset of patients can develop PD after gastric bypass surgery when the common limb length is <400 cm. In patients with intractable PD after gastric bypass surgery, revision surgery for elongation of common limb length to >400 cm is mandatory to avoid PD-related complications.

Abstract
Background and Objectives: Laparoscopic sleeve gastrectomy (LSG) has some unique complications, the most concerning of which is sleeve leak. Staple line reinforcement (SLR) has been suggested as a means of decreasing the risk of sleeve leak, but it increases the cost. However, there is little in the literature regarding the effect of standardized operative technique in reducing the complications and improving the outcomes in LSG. We sought to demonstrate that standardization of the operative procedure and perioperative care is the key to an excellent 30-day outcome and that SLR is not necessary to ensure a negligible staple line leak and bleeding rate. Methods: A prospectively maintained database was analyzed to identify 303 consecutive patients undergoing LSG between July 2010 and November 2017. Data on patient demographics, length of hospital stay, conversion to open surgery, perioperative complications, and mortality were analyzed. Standardized operative technique and postoperative protocol were followed in all cases. SLR was not used in any case. Results: Among 303 cases, there were 15 complications (5%), 5 (1.7%) of which were severe (Clavien-Dindo grade ≥3a). There were no conversions to open procedure, no staple line leaks, and no inpatient deaths in the cohort. No patient was readmitted with an early stricture. Conclusions: The use of a standardized operative and postoperative protocol led to an excellent early outcome in our LSG cases. Standardization may act to obviate the need for routine SLR techniques which are associated with a significant financial cost to both patient and hospital.

Abstract
Background Laparoscopic sleeve gastrectomy (LSG) with staple line reinforcement (SLR) is a popular and safe treatment option for morbid obesity. We have developed, devised, and described our own method of stapleless laparoscopic sleeve gastrectomy, which in our limited study appeared safe, efficacious, and potentially cost-effective. Methods We analyzed the outcome of our modified LSG in a case series of three middle-aged women (median age 42 years old). Our main modification was sutured closure of the stomach rather than the commonly utilized technique of stapled closure. Our primary measure of success was the occurrence of post-operative leak. Secondary measures were (a) length of operation, (b) duration of inpatient stay, and (c) percentage of weight loss at 6 and 12 months post operation. Results Median operative time = 132 min (120–195 min), and median inpatient stays were 2 days. No post-operative leaks were recorded. The median excess weight loss at 6 months was 39% of initial weight loss and 57.7% at 12 months. Conclusions Stapleless LSG has the potential to be an affordable alternative to the traditional LSG. High-powered studies and a formal cost analysis are required.

Abstract
BACKGROUND Bariatric surgery is an effective therapy for morbid obesity but may reduce calcium absorption and significantly decrease the bone mineral density. This study examined the prevalence of secondary hyperparathyroidism (SHPT) in obese subjects during follow-up after different bariatric surgeries. We investigated predictors of SHPT. METHODS We enrolled 1470 obese subjects undergoing bariatric/metabolic surgery with at least 1-year follow-up, including 322 patients undergoing Roux-en-Y gastric bypass (RYGB), 695 undergoing single anastomosis (mini-) gastric bypass (SAGB), 93 undergoing laparoscopic adjustable gastric banding (LAGB), and 360 undergoing sleeve gastrectomy (SG). Five years of data were available for 215 patients. Patients were instructed to supplement their diet according to the guideline. Calcium, parathyroid hormone (PTH), and vitamin D levels were measured before surgery and at 1 and 5 years after surgery. SHPT was defined as PTH > 69 pg/mL. RESULTS The overall prevalence of SHPT was high, 21.0% before surgery and was not different between patients with different bariatric procedures. Pre-operative PTH correlated with age, BMI, and vitamin D levels. Multi-variate analysis confirmed that vitamin D level was the only independent predictor of SHPT before surgery. The prevalence of SHPT increased to 35.4% at 1 year after surgery and 63.3% at 5 years after surgery. SAGB had the highest prevalence of SHPT (50.6%) followed by RYGB (33.2%), LAGB (25.8%), and SG (17.8%) at 1 year after surgery. At 5 years after surgery, SAGB still had the highest prevalence of SHPT (73.6%), followed by RYGB (56.6%), LAGB (38.5%), and SG (41.7%). Serum PTH at 1 year after surgery correlated with decreased BMI and weight loss. Multi-variate analysis confirmed that age, sex, calcium level, and bypass procedure were independent predictor of SHPT after surgery. CONCLUSIONS The prevalence of SHPT is high in morbidly obese patients before bariatric surgery which is related to vitamin D deficiency. The prevalence of SHPT increased continually along with the time after bariatric surgery, especially in patients receiving SAGB, followed by RYGB. The supplementation of vitamin D and calcium have to be higher in bypass procedure, especially in malabsorptive procedure.

Abstract
BACKGROUND In recent years, bariatric surgery was found to have therapeutic potential for the treatment of type 2 diabetes (T2D) in severely obese patients (body mass index [BMI] ≥35 kg/m2) and to reduce cardiovascular disease (CVD) risk and mortality. However, the benefit of CVD risk reduction after metabolic surgery in nonseverely obese T2D patients (BMI <35 kg/m2) remained to be proven. OBJECTIVE To evaluate the CVD risk after metabolic surgery in T2D patients using The UK Prospective Diabetes Study score. SETTING Tertiary referral general hospital, Taiwan, Republic of China. METHODS Outcomes of 392 patients (235 women and 147 men) who had undergone sleeve gastrectomy (87) or gastric bypass (305) for treatment of T2D with 1-year follow-up were assessed. Data were prospectively collected for study, and cerebral and coronary heart disease risk was calculated by using The UK Prospective Diabetes Study risk engine. Outcomes of patients who had undergone different surgical procedures were assessed. RESULTS One year after surgery, weight and glycemic control with complete and partial remission of T2D were significant in most of the patients. The 10-year coronary heart disease risk and fatal coronary heart disease risk were also reduced from 8.8% to 4.6% and from 4.6% to 2.1%, respectively (both P < .001). Similar CVD risk reduction was seen in both patients with BMI ≥35 and BMI <35. Multivariable analysis confirmed that surgical procedure of sleeve gastrectomy was a negative independent predictor of CVD risk reduction after metabolic surgery. CONCLUSION The present study confirms the efficacy of metabolic surgery for the T2D treatment and reduction of CVD risk up to 50% 1 year after surgery. Gastric bypass surgery has more power on CVD risk reduction than sleeve gastrectomy.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is becoming a leading primary bariatric surgery but long-term outcome remains unclear. The amount of food eaten is drastically reduced after LSG and may lead to nutritional deficiencies potentially. The aim of this study is to investigate long-term dietary intake and weight status after LSG. METHODS Forty patients underwent LSG had more than 5-year follow-up with complete clinical data and food frequency questionnaires were analyzed. RESULTS The mean age of subjects is 33.5 years old with mean body mass index (BMI) 37.9 kg/m2. Mean BMI loss at 5 years after LSG is 10.6 kg/m2. Weight regain appeared in 20% of patients. Dietary composition analysis at 5 years showed mean calorie intake of 1230 kcal/day, protein 70 g/day (22.5% of calorie), fat 50 g/day (36.1%), carbohydrate 126 g (41.4%), iron 7.5 mg/day, calcium 536.2 mg/day, and fiber 11.7 g/day. Calorie intake at 5 years after LSG is correlated with weight loss but weight regain is not related to a higher calorie intake. All comorbidities were significantly improved after LSG but hemoglobin and parathyroid hormone significantly changed. Incidence of iron deficiency anemia increased from 7.5% at pre-operation to 41.2% after LSG. Incidence of secondary hyperparathyroidism increased from 17.5 to 60.7%. CONCLUSION LSG is an effective and durable bariatric procedure but with significant changes in nutritional status. Dietary instruction for LSG should include foods rich in protein, iron, calcium, and fiber.

Abstract
BACKGROUND Metabolic surgery has become increasingly accepted for the treatment of type 2 diabetes (T2D). However, there is limited evidence regarding the optimal candidate and surgical procedure. Although a new individualized metabolic surgery (IMS) score was recently proposed for procedure selection, it has yet to be validated. OBJECTIVE To validate the IMS score with regard to remission of T2D after metabolic surgery and compare it with the age, body mass index, C-peptide level, and duration of T2D (ABCD) score. SETTING Hospital-based bariatric center. METHODS A total of 310 T2D patients who underwent gastric bypass and sleeve gastrectomy at an academic center in Taiwan and had a minimum 5-year follow-up (2004-2012) were examined for the predictive power of complete remission using the IMS and the ABCD scoring systems. RESULTS At the 5-year follow-up, weight loss was 27.5%, with mean body mass index decreasing from 37.8 to 27.9 kg/m2, mean glycated hemoglobin decreased from 8.6% to 6.1%, and prolonged remission of T2D achieved in 224 (72.3%) T2D patients. Remission rates were higher in patients who underwent gastric bypass than in those who underwent sleeve gastrectomy (73.6% versus 66.1%; P = .04), regardless of T2D severity, and were 96%, 68%, and 16% in patients with IMS mild, moderate, and severe scores, respectively. Although both scores predicted the success of surgery, the ABCD was better in patients with IMS moderate scores. CONCLUSION Metabolic surgery is an option for T2D patients with obesity. The ABCD score may be better at predicting T2D remission after metabolic surgery compared with the IMS score.

15-year experience of laparoscopic single anastomosis (mini-)gastric bypass: comparison with other bariatric procedures. Surg Endosc 2018; 32:3024-3031. [PMID: 29313123 DOI: 10.1007/s00464-017-6011-1] [Citation(s) in RCA: 51] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2017] [Accepted: 12/13/2017] [Indexed: 12/12/2022]
Abstract
BACKGROUND Laparoscopic single anastomosis (mini-)gastric bypass (LSAGB) has been validated as a safe and effective treatment for morbid obesity. However, data of the long-term outcome remain lacking. METHODS Between October 2001 and December 2015, 1731 morbidly obese patients who received LSAGB as primary bariatric procedure at the Min-Sheng General Hospital were recruited. Surgical outcome, weight loss, resolution of comorbidities, and late complications were followed, then compared with groups of laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG). All data derived from a prospective bariatric database and a retrospective analysis were conducted. RESULTS The average patient age was 33.8 ± 10.4 years with a mean body mass index (BMI) of 40.4 ± 7.7 kg/m2. Of them, 70.0% were female while 30.0% were male. Mean operating time, intraoperative blood, and hospital stay of LSAGB were 124.6 ± 38.8 min, 39.5 ± 38.7 ml, and 5.0 ± 4.1 days, respectively. The 30-day post-operative major complication occurred in 30 (1.7%) of LSAGB patients, 16 (2.0%) of LRYGB, and 15 (1.4%) of LSG patients. The follow-up rates at 1, 5, and 10 years were 89.3, 52.1, and 43.6%, respectively. At postoperative 1, 5, and 10 years, the mean percentage of weight loss (%WL) of LSAGB patients were 32.7, 32.2, and 29.1%, and mean BMI became 27, 26.9, and 27 kg/m2, respectively. The LSAGB had a higher weight loss than LRYGB and LSG at 2-6 years after surgery. LSG had a lower remission rate in dyslipidemia comparing to LSAGB and LRYGB. The overall revision rate of LSAGB is 4.0% (70/1731) which was lower than the 5.1% in LRYGB and 5.2% in the LSG. CONCLUSION LSAGB is an effective procedure for treating morbid obesity and metabolic disorders, which results in sustained weight loss and a high resolution of comorbidities.

Abstract
INTRODUCTION Laparoscopic sleeve gastrectomy (LSG) has become one of the most commonly performed bariatric procedures, largely due to several advantages it carries over more complex bariatric procedures. LSG is generally considered a straightforward procedure, but one of the major concerns is a staple line leak. OBJECTIVE The objectives of this study are to evaluate the correlation between surgeon's experience and leak rate and to assess the different risk factors for developing a gastric leak after LSG. SETTING Private hospital, France. METHODS The analysis of a single surgeon's yearly leak rate since the introduction of LSG for possible risk factors was done. RESULTS A total of 2012 LSGs were performed in between September, 2005 and December, 2014. Twenty cases (1 %) of gastric leak were recorded. Of these, 17 patients were women (94.4 %) with a mean age of 39.4 years (range 22-61) and mean body mass index (BMI) 41.2 kg/m(2) (range 34.8-57.1). On a yearly basis, the leak rate was 4.8 % (2006), 5.7 % (2007), 0 (2008), 2.6 % (2009), 2 % (2010), 0.8 % (2011), 0.6 % (2012), 0.2 % (2013), and 0 (2014). In the first 1000 cases (group A), there were 18 cases of gastric leak and in the last 1000 cases, there were 800 with GORE® SEAMGUARD® Bioabsorbable Staple Line Reinforcement (group B) 2 cases of gastric leak (p = 0.009). A revisional LSG, 395 patients after gastric banding and 61 patients re-sleeve gastrectomy, was performed in 456 cases (22.7 %). There were 3 cases of leak (0.65 %). There were two deaths. CONCLUSION LSG can be performed with a low complication rate. This large series of a single surgeon's experience demonstrated that the leak rate after LSG could be significantly decreased over time with changes in techniques.

Abstract
BACKGROUND Gastric leaks and bleeding are the most important complications after laparoscopic sleeve gastrectomy (LSG). The use of absorbable membranes as staple line reinforcement may decrease this risk. On the other hand, these materials bring additional costs and their economic impact is not well known. The purpose of this study was to assess the clinical and economic performance of one of the commercially available buttressing absorbable materials when treating a high-risk population. METHODS A retrospective, observational, and comparative study was conducted at Montpellier University Hospital, France, between July 2013 and September 2014. Patients undergoing LSG, who were at a high risk for leaks and bleeding, were included and treated according to two groups: no buttressing (July 2013 to January 2014) and buttressing (February 2014 to September 2014). Clinical and economic outcomes were measured throughout the first 6 months. RESULTS Two hundred two patients were included in the study: 116 during the no stapling reinforcement period and 86 during the buttressing period. Baseline characteristics were similar. There was no significant difference between the two groups regarding gastric leaks. However, buttressing reduced hemorrhagic complications (0 vs 8.6 %, p = 0.005) and decreased average total hospital costs for the first hospitalization (5768 vs 6025 €, p < 0.001), as well as 6-month total inpatient cost (5944 vs. 6246 €, p < 0.001). CONCLUSIONS Staple line reinforcement with absorbable material reduces bleeding in high-risk population. Therefore, this type of material can also result in cost-savings.

Abstract
INTRODUCTION Laparoscopic sleeve gastrectomy (LSG) is one of the most frequently performed bariatric procedures performed worldwide. However, staple line-related complications have become a major challenge for bariatric surgeons. The aim of this study was to evaluate the morbidity in a cohort of patients who underwent LSG with imbricated oversewing of the staple line at a single high-volume center. MATERIALS AND METHODS We retrospectively reviewed prospectively collected data for all patients who underwent LSG to treat obesity at our institution from January 2010 to September 2016. All practitioners had undergone training with a single senior bariatric surgeon using oversewing as staple line reinforcement (SLR). RESULTS In total, 1023 LSGs were performed (female, 67.3%; mean age, 40.6 ± 10.8 years; median preoperative body mass index, 37 ± 4.5 kg/m2). The mean operative time was 67.6 ± 23.4 min (range, 30-150 min). The rate of conversion to open surgery was 0.3%. Early complications were noted in 18 patients (1.8%), including 5 cases of bleeding (0.5%). No leaks, stenosis, or mortality occurred. CONCLUSIONS LSG is a safe technique, but staple line-associated complications can be life-threatening. In this series, no leaks occurred from the very beginning of the surgeons' experience in LSG. Imbricated oversewing of the staple line, proper mentoring, and performance of surgery in appropriate settings are good approaches to decreasing complications.

Abstract
INTRODUCTION Morbidly obese patients have lower quality of life (QOL) when compared to the general population. So far, no studies have compared gender and procedural differences in gastrointestinal QOL after sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB). METHODS Patients before and after bariatric surgery completed the gastrointestinal quality of life index (GIQLI), a 36-item questionnaire with five subscores. Differences between SG and RYGB were analyzed, as were gender differences. RESULTS Some 186 patients completed the questionnaire, 75 before surgery, 56 within 6 months, and 55 within 24 months after surgery. Total GIQLI score and all subscores were significantly better within 24 months after surgery (80.9 ± 19.2 vs. 109.2 ± 17.7, p < 0.001). The specific gastrointestinal items 'feeling of fullness', 'eating pleasure', 'slow speed of eating', and 'diarrhea' were also significantly better after surgery whereas many other gastrointestinal items were not different. Total GIQLI score was significantly higher for SG than for RYGB within 6 months, while there were no significant differences within 24 months after surgery. There were also no significant differences in specific gastrointestinal items between SG and RYGB within 24 months after surgery and in total GIQLI score between female and male patients. CONCLUSION Total GIQLI score and all subscores were higher within 24 months after bariatric surgery. Total GIQLI score was significantly higher after SG when compared to RYGB within 6 months, but not different within 24 months after surgery. There was no difference in total GIQLI score between female and male patients.

Abstract
BACKGROUND Recent studies showed that fetuin-A and matrix metalloproteinase-7 (MMP-7) are type 2 diabetes mellitus (T2DM)-associated markers. Bariatric surgery not only reduces body weight but also improves T2DM. This study aimed to investigate the changes of fetuin-A and MMP-7 in obese subjects with and without T2DM after bariatric surgery. METHODS We enrolled 130 obese subjects that received bariatric surgery, including 41 Roux-en-Y gastric bypass (RYGB), 67 mini-gastric bypass (MGB), and 22 sleeve gastrectomy (SG) patients. Forty-three patients suffered from T2DM prior to surgery. The fasting serum fetuin-A and MMP-7 levels were measured before and 1 year after surgery. RESULTS Only five of 43 patients remained diabetic after surgery. Preoperative T2DM patients had higher fetuin-A and MMP-7 levels than non-T2DM subjects. RYGB, MGB, and SG all decreased the fetuin-A levels 1 year after the operation. The MMP-7 levels were not changed after RYGB, MGB, or SG. In multivariate analyses, the preoperative fetuin-A was significantly related to the diastolic blood pressure (DBP) and glycosylated hemoglobin (HbA1c), while the postoperative fetuin-A was independently related to the waist-to-hip ratio and HbA1c. Moreover, the preoperative MMP-7 level was significantly related to age, DBP, aspartate transaminase, alanine transaminase, and gamma-glutamyl transferase (rGT), while the postoperative MMP-7 level was independently related to age and rGT. CONCLUSIONS The fetuin-A and MMP-7 levels are both higher in obese T2DM than non-T2DM subjects. The level of fetuin-A is reduced after RYGB, MGB, and SG, but the level of MMP-7 remains unchanged.

Abstract
BACKGROUND Metabolic surgery is a novel therapy for mild obesity (BMI 30-35 Kg/m(2)) in type 2 diabetes mellitus (T2DM) patients. The ABCD score, which comprise age, BMI, C-peptide level, and duration of T2DM (years), was reported as useful in predicting the success of T2DM treatment using metabolic surgery. This study examines gastric bypass and sleeve gastrectomy as a salvage treatment for non-obese (BMI < 30 kg/m(2)) T2DM patients and evaluates the role of ABCD scores. METHODS From January 2007 to July 2013, 512 (71.2%) of 711 T2DM patients enrolled in a metabolic surgical program had at least 1-year follow-up were recruited. Clinical data and outcomes of 80 (15.6%) patients with BMI < 30 Kg/m(2) were compared with those of the other 432 (84.4%) patients with BMI ≥ 30 Kg/m(2). Complete remission was defined as HbA1c ≤ 6%, and partial remission was defined as HbA1c < 6.5%. A binary logistic regression was used to identify predictors of T2DM remission. RESULTS Mean age of the 80 non-obese T2DM patients was 47.7 ± 9.1 years, and mean HbA1c and disease duration were 9.1 ± 1.8% and 6.5 ± 5.1 years, respectively. Mean total body weight loss was 17.1 ± 7.4% at 1 year, and mean BMI decreased from 26.9 ± 2.2 to 22.7 ± 2.5 kg/m(2) at 1 year. Complete remission of T2DM was achieved in 25.0% of patients, and partial remission was achieved in 23.8%. The complete remission rate was significantly lower than the 49.5% found in patients with BMI 30-35 and 79.0% of patients with BMI > 35 Kg/m(2). In univariate analysis, non-obese patients who had T2DM remission after surgery were heavier and had a wider waist, higher C-peptide levels, shorter disease duration, more weight loss, and higher ABCD score than those without remission. The ABCD score remained the only independent predictor of success after multivariate logistical regression analyses (P = 0.003). CONCLUSIONS Metabolic surgery may be useful in achieving glycemic control of selected non-obese T2DM patients. The ABCD score is a simple multidimensional grading system that can predict the success of T2DM treatment.

Abstract
BACKGROUND Emerging evidence has shown that bariatric/metabolic surgery ameliorates type 2 diabetes (T2DM) in mildly obese patients (BMI < 35 kg/m(2)) but long-term data is inadequate. We investigated the change of the quality of life after metabolic surgery in not well-controlled T2DM patients with BMI < 35 kg/m(2). METHODS The quality of life was measured by the gastrointestinal quality of life index (GIQLI), a 36-item questionnaire divided into three domains of general health and one domain of specific gastro-intestinal symptoms, administered before operation, at 3, 6, and 12 months after surgery. A control group matched in age, gender, and BMI was recruited for comparison. RESULTS A total of 86 patients were enrolled, and the preoperative BMI and HbA1C (mean ± SD) were 30.7 ± 2.8 kg/m(2) and 9.3 ± 2.1 %, respectively. At 1 year after surgery, the BMI and HbA1C were 24.3 ± 2.3 kg/m(2) and 6.2 ± 1.1 %, respectively. There was a significantly improvement in all of the measures of glucose metabolism. Complete remission (HbA1C < 6.0 %) was achieved in 56 subjects (65 %) at 12 months. The GIQLI score was significantly impaired in T2DM patients before surgery compared with the control group. The GIQLI score significantly increased from 109.2 ± 20.0 to 116.1 ± 14.2 points 1 year after surgery. The patients had improvement in the three domains of general health (social, physical, and emotional function) without a difference with the normal control but deteriorated in the domain of specific symptoms. Most of the patients experienced symptoms including abdominal pain, bloating, flatulence, belching, abdominal noise, regurgitation, dysphagia, slow eating speed, nausea, bowel urgency, and incontinence after metabolic syndrome. CONCLUSIONS Health-related QOL improved dramatically after metabolic surgery for not well-controlled T2DM patients with BMI < 35 kg/m(2), but patients might develop specific gastro-intestinal symptoms after surgery.

Staple Line Reinforcement During Laparoscopic Sleeve Gastrectomy: Absorbable Monofilament, Barbed Suture, Fibrin Glue, or Nothing? Results of a Prospective Randomized Study. J Gastrointest Surg 2016; 20:361-6.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is associated with serious complications, such as staple line (SL) leaks and bleeding. In order to prevent the occurrence of these complications, surgeons have advocated the need to strengthen the staple line. The aim of this randomized controlled study was to compare the efficacy of three different ways of strengthening of the SL in LSG in preventing surgical post-operative complications. METHODS Between April 2012 and December 2014, 600 patients (pts) scheduled for LSG were prospectively randomized into groups without SL reinforcement (group A) or with SL reinforcement including fibrin glue coverage (group B), or oversewn SL with imbricating absorbable (Monocryl™; group C) or barbed (V lock®) running suture (group D). Primary endpoints were post-operative leaks, bleeding, and stenosis, while secondary outcomes consisted of the time to perform the staple line reinforcement (SLR) and total operative time. RESULTS Mean SLR operative time was lower for group B (3.4 ± 1.3 min) compared with that for groups C (26.8 ± 8.5 min) and D (21.1 ± 8.4 min) (p < 0.0001). Mean total operative time was 100.7 ± 16.4 min (group A), 104.4 ± 22.1 min (group B), 126.2 ± 18.9 min (group C), and 124.6 ± 22.8 (group D) (p < 0.0001). Post-operative leaks, bleeding, and stenosis were recorded in 14 pts (2.3 %), 5 pts (0.8 %), and 7 pts (1.1 %), respectively, without statistical difference between the groups. CONCLUSION Our study suggests that SLR during LSG, with an imbricating or non-imbricating running suture or with fibrin glue, is an unrewarding surgical act with the sole effect of prolonging the operative time.

Abstract
AIM: To investigate the effect of staple line reinforcement materials on decreasing complications related to sleeve gastrectomy.
METHODS: In this retrospective study, we analyzed 84 patients who had sleeve gastrectomy due to obesity between April 2012 and April 2015. Sleeve gastrectomy procedure was performed in patients with a body mass index (BMI) more than 40 kg/m2, and the ones with a BMI between 32 and 40 kg/m2 in the presence of comorbid diseases. Reinforcement materials were used in 45 patients while they were not used in 39 patients. Materials such as Peristrip, 3/0 prolene, and V-lock were used for reinforcement in the reinforcement group (RG), and the materials used showed variations during the study period. The baseline characteristics, duration of surgery, hospital stay, comorbidities including hypertension, type 2 diabetes mellitus, hypertension, hepatosteatosis, gallstones, osteoarthritis, gastroesophageal reflux, sleep disorders, as well as the complications including leaks and bleeding after surgery were recorded and compared between the reinforcement and non-RGs (NRGs).
RESULTS: There were no differences between the reinforcement and NRGs for baseline characteristics including age (P = 0.689), gender (P = 0.057), height (P = 0.483), weight (P = 0.889), BMI (P = 0.971), hospital stay (P = 0.888), or duration of surgery (P = 0.229). The most common comorbidities in the RG were hypertension (24.4%) and hepatosteatosis (24.4%), while type 2 diabetes mellitus (28.2%) and hepatosteatosis (28.2%) were the most frequent comorbidities in the NRG. There were no differences between the reinforcement and NRGs for the rates of comorbidities (P > 0.05). Leak was observed in one (2.2%) patient in the RG, and there was leak in 2 (5.1%), and bleeding in 2 (5.1%) patients in the NRG. There were no differences between the reinforcement and NRGs for the rate of staple line leaks (P = 0.446) or bleeding (P = 0.213). One of the patients with leak died in the NRG while there were no deaths in the RG.
CONCLUSION: Although staple line reinforcement materials decreased morbidity and mortality, the differences between the two groups were not statistically significant.

Abstract
Single-anastomosis (mini-) gastric bypass (SAGB) was proposed by Dr. Robert Rutledge. Criticism and prejudice against this procedure was raised by surgeons who preferred a more difficult procedure, laparoscopic Roux-en-Y gastric bypass (RYGB). Increasing data indicates the procedure is an effective and durable bariatric procedure. SAGB has lower operation risks compared to RYGB. The weight loss is better after SAGB because of a greater malabsorptive component than RYGB, but SAGB had a higher incidence of micronutrient deficiencies. Randomized controlled trial and long-term data demonstrate that SAGB can be regarded as a simpler and safer alternative to RYGB. We propose this procedure to be renamed "single-anastomosis gastric bypass (SAGB)" because the key feature of SAGB is the "single anastomosis" compared with the two anastomoses of RYGB.

Abstract
BACKGROUND Laparoscopic Nissen fundoplication is an effective treatment for gastroesophageal reflux disease (GERD). However, there is no consensus for the surgical treatment of GERD in morbidly obese patients. METHODS Twenty-five morbidly obese patients with GERD underwent our novel procedure, laparoscopic Nissen fundoplication with gastric plication (LNFGP), and were monitored for 6 to 18 months. Operative complication, weight loss, and GERD symptoms were monitored. RESULTS The study subjects consisted seven males and 18 females. The average age was 38.2 years (from 18 to 58), and the mean BMI was 37.9 kg/m(2) (from 31.5 to 56.4). The mean operative time was 145.6 min (from 105 to 190). All procedures were performed via laparoscopic surgery. Two patients (8%) displayed a major 30-day perioperative complication. The first patient had an acute leak on the second postoperative day. The patient received a laparoscopic revision sleeve gastrectomy and was discharged 5 days later after an uneventful recovery. Another patient developed an intra-abdominal abscess 3 weeks after surgery and received laparoscopic drainage and a revision sleeve gastrectomy. Upon follow-up, only four (16%) patients experienced occasional acid regurgitation symptoms; however, no anti-acid medication was required. A significant decrease in the prevalence of erosive esophagitis (80 vs. 17%) after LNFGP was observed. The mean weight loss was 9.7, 14.1, 17.9, and 18.1% at 1, 3, 6 and 12 months, respectively. The mean BMI decreased to 30.8 kg/m(2) 1 year post surgery with a mean body weight loss of 25 kg. CONCLUSIONS LNFGP appears to be an acceptable treatment option for treating GERD in morbidly obese patients who refuse Roux-en-Y gastric bypass. However, further study is indicated to verify this novel procedure.

Abstract
This study aims to review the obesity literature in order to assess the impact of bariatric surgery on quality of life and the between-study variation by examining the standardized mean magnitude of effect in change in the levels of quality of life. The following databases EMBASE, PubMed, PsycINFO, CINAHL, the Cochrane Library and Web of Science were systematically searched for studies examining change in quality of life in adults receiving bariatric surgery for obesity. Seventy-two studies were included with a total of 9,433 participants treated for obesity with bariatric surgery. The average impact of bariatric surgery on quality of life corresponded to an effect size of 0.88 (95% CI: 0.80-0.96), indicating that bariatric surgery has a significant positive influence on quality of life in general. The impact varied considerably across studies with bariatric surgery showing a significantly greater positive influence on physical quality of life compared to mental quality of life. Bariatric surgery is effective in improving quality of life, especially when looking at physical well-being. Greater focus on the psychological well-being of the person undergoing surgery for obesity may lead to a better post-surgery prognosis for more people.

Abstract
Morbid obesity and obesity-related comorbidities are major public health problems around the world, including in East Asia. Although Asian populations have been shown to have an elevated risk of type 2 diabetes mellitus, hypertension, and hyperlipidemia at a relatively lower BMI than Western populations, the Asian perspective on bariatric and metabolic surgeries has not been actively discussed until recently. Bariatric surgery in East Asia has undergone a paradigm shift since the first laparoscopic vertical bariatric surgery was performed in Taiwan in 1998, which was subsequently followed by the introduction of laparoscopic adjustable gastric banding, Roux-en-Y gastric bypass, and mini-gastric bypass. Since 2006, use of laparoscopic sleeve gastrectomy has remarkably increased because of its ease, speed, and safety. With regard to metabolic surgery, a randomized controlled trial in Taiwan demonstrated that laparoscopic Roux-en-Y gastric bypass is more effective than laparoscopic sleeve gastrectomy for surgical treatment of poorly controlled type 2 diabetes mellitus and metabolic syndrome. In this article, we describe the history of bariatric procedures, revision surgeries, weight-loss effect, and metabolic surgeries in Asian populations, and we also discuss minimally invasive bariatric surgery with some important citations.

Bariatric versus diabetes surgery after five years of follow up. Asian J Surg 2015; 39:96-102. [PMID: 26235458 DOI: 10.1016/j.asjsur.2015.04.001] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2014] [Revised: 04/16/2015] [Accepted: 04/28/2015] [Indexed: 01/13/2023] Open
Abstract
BACKGROUND Bariatric surgery (BS) is totally different from diabetes surgery (DS) in the patient characters, goals of surgery, and management although similar in surgical procedure. Comparison of BS and DS with long-term data is lacking. MATERIALS AND METHODS A retrospective review of patients who received BS and patients who received DS at Min-Sheng General Hospital from 2007 to 2013 was designed. All inpatient and outpatient follow-up data were analyzed. Patients undergoing BS for the treatment of morbid obesity were compared with patients undergoing metabolic surgery for the treatment of type 2 diabetes mellitus (T2DM). Patients who received revision surgeries were excluded. The main outcome measures were: (1) operation risk; (2) weight loss; and (3) diabetes remission. RESULTS Between 2007 and 2013, 2073 patients who received BS and 741 patients who received DS were recruited from both centers. DS patients were older (41.1 ± 10.9 years vs. 33.1 ± 9.3 years, p < 0.05) and were more likely to be male (40.2% vs. 28.2%, p < 0.05) and to have diabetes (100% vs. 6.0%, p < 0.05), however, they had similar body mass index (BMI) (37.9 ± 8.0 vs. 38.5 ± 9.7, p = 0.78) compared to the BS patients. Surgical procedures are significantly different between the two groups (73.3% of the DS surgeries were gastric bypass procedure, whereas this procedure made up only 47.1% of BS surgeries). Although the major complication rates were similar (2.0% vs. 2.4%), the DS program had a significant higher mortality rate than the BS program (0.54% vs. 0.1%; p < 0.05). At the 5-year follow-up time point, 58.0% of the BS patients had achieved successful results (weight loss > 30%) and 80% of the DS patients had complete remission of their diabetes [hemoglobin A1c (HbA1c) < 6.0%]. Both the DS and the BS group had good results in up to 85% of the patients at the 5-year follow-up time point. CONCLUSION The clinical profiles were very different between the BS and the DS programs. Both programs achieved the desired outcomes equally well, however, the DS program had a higher risk than the BS program.

Abstract
INTRODUCTION Vertical banded gastroplasty (VBG) has been the procedure of choice for bariatric surgeries since the 1980s. However, long-term results of VBG have been reported with different opinions, and new restrictive procedures have been innovated and showing variable results. The aim of this study is to analyze the long-term results of our VBG patients. PATIENT AND METHODS Between June 1998 and May 2002, 652 morbidly obese patients received VBG, with the initial 40 patients having open procedures and the subsequent 612 patients using a laparoscopic approach. Operative complications, weight loss, and late complications were followed and compared with groups of laparoscopic adjustable gastric banding (LAGB) and sleeve gastrectomy (LSG). RESULTS Mean age, preoperative weight, and body mass index (BMI) were 30.96 years, 108.83 kg, and 40.63 kg/m(2), respectively. The overall early postoperative complication rate was 3.4% (22/652). The excess weight loss percentages at 1, 2, 5, and 10 years were 61.04, 59.70, 51.11, and 42.0%, respectively. BMI at 1, 2, 5, and 10 years were 29.64, 29.71, 31.33, and 31.73 kg/m(2), respectively. This result is inferior to the 67% excess weight loss in the LSG group, but is higher than the 38% excess weight loss of the LAGB group. The revision rate is 13.19% (86/652) up to now. Revision surgery was required in 28 (14.0%) patients in the LAGB group and 8 (1.3%) in the LSG group. CONCLUSION VBG was an operation with acceptable outcome for treating morbid obesity and metabolic disorders. It sets a standard for new restrictive procedures.

Abstract
BACKGROUND DATA Bariatric/metabolic surgery has been proposed for the treatment of inadequately controlled type 2 diabetes mellitus (T2DM) in obese patients. However, prediction on successful long-term remission of T2DM after metabolic surgery has not been clearly studied. Our objectives were to evaluate rates of long-term remission of T2DM after metabolic surgery and determine the independent predictors of remission. METHODS Outcomes of 157 patients who underwent metabolic surgery between 2006 and 2009 and who had complete 5-year follow-up data were assessed. Prolonged complete remission was defined as glycated hemoglobin (HbA1c) less than 6 % without diabetes medication up to 5 years. Predictors of prolonged remission studies included patient characteristics such as glucose level, HbA1c, body weight, waist circumference, blood pressure, total cholesterol, LDL, triglyceride, uric acid, AST, alanine transaminase (ALT), albumin, insulin, C-peptide, iron, calcium, complete blood cell count, the ABCD score (a multidimensional grading system composed of age, body mass index (BMI), C-peptide levels, and duration of T2DM), and postoperative weight loss. RESULTS At 5 years after surgery, the weight loss was 27.1 % and the mean BMI decreased from 39.8 to 28.8 kg/m(2). The mean HbA1c decreased from 8.3 to 6.0 %. A significant number of patients had improvement in their glycemic control, including 97 (71.3 %) patients who had complete remission (HbA1c < 6.0 %), 27 (19.9 %) partial remission (HbA1c < 6.5 %), and 12 (8.8 %) improved condition (HbA1c < 7 %). In univariate analysis, patients with prolonged T2DM remission after surgery were younger and heavier; had a wider waist, higher C-peptide, shorter duration of T2DM, higher liver enzyme, higher insulin resistance, higher C-peptide level, and higher white blood cell count; were taking smaller insulin dosage; had higher ABCD score; and had greater weight loss than those without remission. Multivariate logistical regression analyses showed that the ABCD score and weight loss were the only predictors of remission after metabolic surgery. CONCLUSIONS Metabolic surgery is a treatment option for patients with obesity and T2DM. Baseline ABCD score and weight loss have a major influence on outcome.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is a popular stand-alone bariatric surgery, despite a paucity of long-term data. Hence, this study is to report the long-term outcome of LSG as primary bariatric procedure and the result of revisional surgery. METHODS With retrospective analysis of a prospective bariatric database, participants who defaulted clinic follow-up were interviewed by telephone. A total of 667 LSG was performed as primary bariatric procedure (2006-2012) with mean age of 34.5 ± 9.7 years old, female 74.7%, mean body mass index (BMI) 37.3 ± 8.1 kg/m(2). A 36-F bougie was used for all cases. RESULTS There were 61 patients available with long-term data. The weight loss outcome at 1 year, 2 years, 3 years, 4 years, and 5 years showed a mean BMI 26.3, 25.2, 25.3, 27.1, and 26.2 with mean excess weight loss (EWL) 76.0%, 79.6%, 77.3%, 73.4%, and 72.6% respectively. However, 17% patients developed de novo gastro-esophageal reflux disease (GERD). Eighteen patients (2.2%) needed surgical revisions due to weight regain (n = 6), persistent type 2 diabetes mellitus (T2DM; n = 2), stricture (n = 2), and GERD (n = 8). The revision resulted in an additional mean excess weight loss of 23.8% with mean BMI 24.9 kg/m(2) at 6 months postoperatively. There was a 23.7% mean reduction of HbA1c with one patient who was in complete diabetic remission at 1 year. CONCLUSION Our results showed LSG is a durable bariatric procedure with > 70% EWL at 5 years despite a high incidence of GERD. The need for revision of LSG is low and mainly for GERD.

Abstract
Background Stand-alone laparoscopic sleeve gastrectomy (LSG) has been found to be effective in producing weight loss but few large, one-center LSG series have been reported. Gastric leakage from the staple line is a life-threatening complication of LSG, but there is controversy about whether buttressing the staple line with a reinforcement material will reduce leaks. We describe a single-center, 518-patient series of LSG procedures in which a synthetic buttressing material (GORE® SEAMGUARD® Bioabsorbable Staple Line Reinforcement) was used in the most recently treated patients. Methods We retrospectively reviewed the medical records of all patients who underwent LSG in our unit between September 2007 and December 2011. Patients treated before August 2009 did not receive the staple line reinforcement material (n = 186), whereas all patients treated afterward did (n = 332). Results The percentages of excess weight loss in the 518 patients (mean age, 41 years; 82 % female; mean preoperative body mass index, 44 kg/m2) were 67 % (79 % follow-up rate) at 6 months postoperatively, 81 % (64 %) at 1 year, and 84 % (30 %) at 2 years. Type 2 diabetes resolved in 71 % of patients (91/128). Patients given reinforcement material had baseline characteristics similar to those in the no-reinforcement-material group, but had no postoperative staple line leaks or bleeding. The no-reinforcement group had three leaks (p = 0.045) and one case of bleeding. Conclusions LSG resulted in substantial short-term weight loss. Use of the bioabsorbable staple line reinforcement material may decrease leaks after LSG.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is becoming a primary bariatric surgery for obesity and related diseases. This study presents the outcome of LSG with regard to the remission of type 2 diabetes mellitus (T2 DM) and the usefulness of a grading system to categorize and predict outcome of T2 DM remission. METHODS A total of 157 patients with T2 DM (82 women and 75 men) with morbid obesity (mean body mass index 39.0±7.4 kg/m(2)) who underwent LSG from 2006 to 2013 were selected for the present study. The ABCD score is composed of the patient's age, body mass index, C-peptide level, and duration of T2 DM (yr). The remission of T2 DM after LSG was evaluated using the ABCD score. RESULTS At 12 months after surgery, 85 of the patients had complete follow-up data. The weight loss was 26.5% and the mean HbA1c decreased from 8.1% to 6.1%. A significant number of patients had improvement in their glycemic control, including 45 (52.9%) patients who had complete remission (HbA1c<6.0%), another 18 (21.2%) who had partial remission (HbA1c<6.5%), and 9 (10.6%) who improved (HbA1c<7%). Patients who had T2 DM remission after surgery had a higher ABCD score than those who did not (7.3±1.7 versus 5.2±2.1, P<.05). Patients with a higher ABCD score were also at a higher rate of success in T2 DM remission (from 0% in score 0 to 100% in score 10). CONCLUSION LSG is an effective and well-tolerated procedure for achieving weight loss and T2 DM remission. The ABCD score, a simple multidimensional grading system, can predict the success of T2 DM treatment by LSG.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (SG) has become accepted as a stand-alone procedure as a less complex operation than laparoscopic duodenojejunal bypass with sleeve gastrectomy (DJB-SG). OBJECTIVES The aim of this study was to compare one-year results between DJB-SG and SG. SETTING University hospital. METHODS A total of 89 patients who received a DJB-SG surgery were matched with a group of SG that were equal in age, sex, and body mass index (BMI). Complication rates, weight loss, and remission of co-morbidities were evaluated after 12 months. RESULTS The mean preoperative patient BMI in the DJB-SG and SG groups was similar. There were more patients with type 2 diabetes mellitus (T2DM) in the DJB-SG group than in the SG group. The mean operative time and length of hospital stay (LOS) were significantly longer in the DJB-SG group than in the SG group. At 12 months after surgery, the BMI was lower and excess weight loss higher in DJB-SG than SG. Remission of T2DM was greater in the DJB-SG group. Low-density lipoprotein, total cholesterol, and metabolic syndrome (MS) improved after operation in both groups. CONCLUSIONS In this study DJB-SG was superior to SG in T2DM remission, triglyceride improvement, excess weight loss, and lower BMI at 1 year after surgery. Adding duodenal switch to sleeve gastrectomy increases the effect of diabetic control and MS resolution.

Abstract
BACKGROUND Staple-line leak is a life-threatening complication of laparoscopic sleeve gastrectomy. Reinforcement materials have been reported to lower the risk of staple-line bleeding, but their effects on leak risk have not been elucidated. The aim of this study was to compare the effects of two supportive techniques on burst pressures in sleeved gastrectomy specimens. MATERIALS AND METHODS Thirty patients who underwent laparoscopic sleeve gastrectomy were evaluated. The resected sleeve gastrectomy specimens were categorized into three groups. Group 1 had no extra support in the staple line, Group 2 had oversewing with continuous suture on the staple line, and Group 3 had fibrin sealant (Tisseel(®); Baxter, Deerfield, IL) on the staple line. The end point was the first detectable leakage, at which point leak pressure and the anatomic site of leakage were recorded. RESULTS Thirty sleeved gastrectomy specimens were included (each group included 10 specimens). There were no differences among group in terms of age, sex, and body mass index. The leak pressure was significantly higher (106±10.5 mm Hg) in Group 2 (P<.01). Leaks occurred significantly more frequently in the staple line than in the staple junction points (P=.014). CONCLUSIONS Oversewing the staple line with 3-0 Vicryl(®) (Ethicon, Somerville, NJ) suture significantly increased the strength of the staple line. Increases in intraluminal pressure are known to be one of the significant risks in leak etiology. Thus, we concluded that oversewing the staple line with 3-0 Vicryl suture can be beneficial in the prevention of leaks. However, further work is necessary in this area of research.
