Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is the most commonly performed bariatric procedure worldwide. Many factors have been investigated in the literature to predict weight loss outcomes after LSG. However, insufficient data regarding the resected stomach weight (RGW) exists. This retrospective study aimed to investigate the association between RGW and weight loss outcomes 1 year after LSG. MATERIALS AND METHODS Fifty-four patients who underwent LSG in a tertiary care center were evaluated retrospectively. The statistical analyses were performed to investigate the correlation between preoperative demographics, RGW, and the excess weight loss percentage (%EWL) and percent total weight loss (%TWL). RESULTS The mean RGW was 169.7±40.1, ranging from 101 to 295 grams. The RGW was significantly correlated with preoperative weight (r=0.486; P<0.001), body mass index (r=0.420; P=0.002), and age (r=0.327; P=0.01). However, RGW did not predict postoperative weight loss, as measured by percent total weight loss (%TWL) and percent excess weight loss (%EWL), respectively (r=0.044; P=0.75 and r=-0.216; P=0.11). Multiple linear regression analysis identified age as a negative predictor for both %TWL (β=-0.351, P=0.005) and %EWL (β=-0.265, P=0.03), while preoperative body mass index was a negative predictor for %EWL (β=-0.469, P<0.001). CONCLUSION The RGW, although correlated with patient characteristics, does not serve as a reliable predictor of postoperative weight loss in the first year after LSG. Further research is needed to improve predictive models and patient care in bariatric surgery.

The Evaluation of Gastric Emptying Using Nuclear Scintigraphy Compared to Three-Dimensional Multi-detector Computed Tomography (3D-MDCT) Gastric Volumetry in the Assessment of Poor Weight Loss Following Sleeve Gastrectomy. Obes Surg 2024; 34:150-162. [PMID: 37991711 DOI: 10.1007/s11695-023-06951-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 11/08/2023] [Accepted: 11/13/2023] [Indexed: 11/23/2023]
Abstract
BACKGROUND Poor weight loss and weight regain are principal challenges following laparoscopic sleeve gastrectomy (LSG). There is a lack of standardised assessments and diagnostic tests to stratify the status post-LSG and determine whether anatomical or physiological problem exists. We aimed to compare nuclear scintigraphy gastric emptying with CT volumetric analysis of sleeve anatomy and determine the impact of anatomy on physiological function and its correlation with weight loss. MATERIALS AND METHODS Patients greater than 12 months post-LSG were categorised into optimal weight loss (OWL) (n = 29) and poor weight loss groups (PWL) (n = 50). All patients underwent a protocolised nuclear scintigraphy and three-dimensional multi-detector computed tomography (3D-MDCT) gastric volumetry imaging. RESULTS Post-operative % total weight loss in OWL was 26.2 ± 10.5% vs. 14.2 ± 10.7% in the PWL group (p value < 0.0001). The PWL group had significantly more delayed gastric emptying half-time than OWL (34.1 ± 18.8 vs. 19.5 ± 4.7, p value < 0.0001). Gastric emptying half-time showed statistically significant correlations with weight loss parameters (BMI; r = 0.215, p value 0.048, %EWL; r = - 0.336, p value 0.002 and %TWL; r = - 0.379, p value < 0.001). The median gastric volume on 3D-MDCT did not differ between the OWL (246 (IQR 50) ml) and PWL group (262 (IQR 129.5) ml), p value 0.515. Nuclear scintigraphy gastric emptying half-time was the most highly discriminant measure. A threshold of 21.2 min distinguished OWL from PWL patients with 86.4% sensitivity and 68.4% specificity. CONCLUSION Nuclear scintigraphy is a potentially highly accurate tool in the functional assessment of sleeve gastrectomy physiology. It appears to perform better as a diagnostic test than volumetric assessment. Gastric volume did not correlate with weight loss outcomes. We have established diagnostic criteria of greater than 21 min to assess sleeve failure, which is linked to suboptimal weight loss outcomes.

Abstract
BACKGROUND To assess the 5-year outcomes of patients undergoing Collis-Nissen gastroplasty for type III-IV hiatal hernia with short esophagus. STUDY DESIGN From a prospective observational cohort of patients who underwent antireflux surgery for type III-IV hiatal hernia between 2009 and 2020, those with short esophagus (abdominal length <2.5 cm) in whom a Collis-Nissen procedure was performed and reached at least 5 years of follow-up were identified. Hernia recurrence, patients' symptoms, and quality of life were assessed annually by barium meal x-ray, upper endoscopy, and validated symptoms and Quality of Life in Reflux and Dyspepsia (QOLRAD) questionnaires. RESULTS Of the 114 patients with Collis-Nissen gastroplasty, 80 patients who completed a 5-year follow-up were included (mean age 71 years). There were no postoperative leaks or deaths. Recurrent hiatal hernia (any size) was identified in 7 patients (8.8%). Heartburn, regurgitation, chest pain, and cough were significantly improved at each follow-up interval (p < 0.05). Preoperative dysphagia disappeared or improved in 26 of 30 patients, while new-onset dysphagia occurred in 6. Mean postoperative QOLRAD scores significantly improved at all dimensions (p < 0.05). CONCLUSIONS Collis gastroplasty combined with Nissen fundoplication provides low hernia recurrence, good control of symptoms, and improved quality of life in patients with large hiatal hernia and short esophagus.

Abstract
PURPOSE Data regarding the associations between percent weight loss and the volume and weight of stomach resected during sleeve gastrectomy (SG) are mixed. The purpose of this study was to evaluate the effect of the size and volume of stomach removed during laparoscopic SG on percent total body weight lost (%TBWL). METHODS An observational case series study was performed on 67 patients for 1 year after SG at a single university-affiliated, tertiary care hospital. Data were collected on demographics, medical history, and %TBWL at 3, 6, and 12 months post-operatively. Pearson's correlation matrices and multiple linear regression analyses were performed. RESULTS Most patients (88.1%) were female with a mean age of 44 years. The mean volume of stomach resected was 1047.0 cubic centimeters, and the median weight resected was 123.0 g. Follow-up data were available for 44 patients at 1-year post-operation. There was no association between the volume and weight of stomach resected and %TBWL at 1-year post-operation; however, greater %TBWL was associated with younger patient age (r = - 0.525, p < 0.001). CONCLUSION One year after SG, no associations between %TBWL and the volume and weight of stomach resected were observed.

Abstract
Background
Gastric pouch volumetry after sleeve gastrectomy reflects successful surgery. We aimed to assess the impact of gastric pouch volume after sleeve gastrectomy on weight loss.
Method
The study was performed for 30 patients (22 females and 8 males) who underwent sleeve gastrectomy. Their ages ranged from 18 to 47 years. All patients underwent (multi-slice CT) MSCT examination at 12 months after surgery with oral administration of effervescent emulsion. Post-processing in multi-planar reconstruction and 3D reconstruction was performed to all cases. Gastric pouch volume was measured and correlated with body weight, body mass index (BMI), % reduction in excess body weight and ∆weight at 1 year.
Results
A significant positive association was found among gastric volume pouch and weight loss (P = 0.04), BMI reduction (P value < 0.0001) and ∆weight (P value = 0.013). A significant inverse association was found among gastric pouch volume and % reduction in excess body weight (P value = 0.013).
Conclusion
MSCT gastric volumetry is the gold standard imaging method for assessment of the gastric pouch volume after sleeve gastrectomy. Significant positive association was found among gastric volume pouch and weight loss, BMI reduction and ∆weight at 1 year, i.e., in spite of large gastric pouch volume at 1 year, there is adequate weight loss, BMI reduction and ∆weight. Yet, significant inverse association was found among gastric pouch volume and % reduction in excess body weight.

Abstract
AbstractLaparoscopic sleeve gastrectomy (LSG) is considerably utilized as a bariatric method for treating morbid obesity through the reduction of stomach volume. The present study attempted to assess the volumetric changes of the gastric reservoir 1 year after LSG using multi-slice spiral computed tomography (MSCT) as well as to verify their association with weight loss. The current study is a prospective study of 40 consecutive morbid obese patients managed with laparoscopic sleeve gastrectomy. All patients were referred to abdominal MSCT besides volumetric measurement of the gastric pouch 1 month and 12 months postoperatively after the LSG. There were statistically substantial differences throughout the whole period of follow-up (p value ≤ 0.05) regarding the ratio of excess weight loss, weight loss, and decreased BMI, in addition to the ratio of excess body mass index loss (% EBMIL) after LSG. Substantial elevation of the overall volume of the gastric reservoir (82.9 SD11 and 171.6 SD23.6 ml at 1 and 12 months, respectively) was observed. However, the current findings did not demonstrate any significant association (r = 0.131, p = 0.491) between excess weight loss percentage and the increase in gastric reservoir volume 1 year postoperatively. Sleeve dilatation is a common finding following sleeve gastrectomy (SG) even after conducting a narrow gastric pouch, yet dilatation was not correlated with insufficient weight loss after 1 year postoperatively. Trial registration number: NCT04880902.

Abstract
BACKGROUND The aim of this study is to evaluate the impact of the actual size and area of the remnant stomach, as measured by Upper gastrointestinal tract radiography, on weight loss after sleeve gastrectomy. MATERIALS AND METHODS From May 2017 to December 2019, 56 patients with morbid obesity were admitted to the Department of Medical and Surgical Sciences, University of Foggia and underwent laparoscopic sleeve gastrectomy. RESULTS 56 patients underwent sleeve gastrectomy with a mean age of 43,5 ± 11 years of which 40 were female. The mean Excess Weight Loss (EWL) at 1 month was 24,09 ± 15,04%, at 6 months was 27,07 ± 19,55% and at 12 months was 69,9 ± 23,7%. The mean Excess Body Mass Index Loss (EBMIL) at 1 month was 23,1 ± 12,5%, at 6 months was 56,6 ± 19,7% and at 12 months was 69,7 ± 23,7%.The EWL % was correlated with the residual stomach area (RSA) at 1 month (r = -0,242 p = 0,072), at 6 months (r = -0,249 p = 0,064) and at 12 months (r = -0,451 p = 0,0005).The EBMIL % was correlated with the RSA at 1 month (r = -0,270; p = 0,043), at 6 months (r = -0,270; p = 0,043) andat 12 months (r = -0,46; p = 0,0004). CONCLUSION A greater postoperative EWL % was correlated with a smaller RSA and this resulted in a statistically significant change at 12 months after surgery.

Abstract
BACKGROUND As a restrictive procedure, laparoscopic sleeve gastrectomy (LSG) relies primarily on the reduction of gastric volume. It has been suggested that an immediate postoperative gastric remnant volume (GRV) may influence long-term results of LSG; however, there are no consensus in this matter. The aim of this study was to assess the reproducibility of different radiographic methods of GRV calculation and evaluate their correlation with the weight loss (WL) after surgery. METHODS This retrospective study evaluated 174 patients who underwent LSG in the period from 2014 to 2017. Using UGI, GRV was measured with 3 different mathematical methods by 2 radiologists. Intraobserver and interobserver calculations were made. Correlation between GRV and WL were estimated with calculations percentage of total weight loss (%TWL) and percentage of excess weight loss (%EWL) after 1, 3, 6, 12, 18, and 24 months postoperatively. RESULTS During analysis of intraobserver similarities, the results of ICC calculation showed that reproducibility was good to excellent for all GRV calculation methods. The intraobserver reproducibility for Reader I was highest for cylinder and truncated cone formula and for Reader II for ellipsoid formula. The interobserver reproducibility was highest for ellipsoid formula. Regarding correlation between GRV and WL, significant negative correlation has been shown on the 12th month after LSG in %TWL and %EWL for every method of GRV calculation, most important for ellipsoid formula (%TWL - r(X,Y) = -0.335, p < 0.001 and %EWL - r(X,Y) = -0.373, p < 0.001). CONCLUSION Radiographic methods of GRV calculation are characterized by good reproducibility and correlate with the postoperative WL.

Abstract
INTRODUCTION Given its feasibility and efficacy, laparoscopic sleeve gastrectomy (LSG) has become a widely accepted bariatric surgery for patients with clinically diagnosed severe obesity. LSG induces anatomical changes and subsequent weight loss which may affect drug pharmacokinetics (PK) and consequently impact dosing regimens. This review aims to examine the effect of LSG on drug PK and identify relevant gastrointestinal physiological alterations. AREAS COVERED PubMed, Embase, Scopus, and the Cochrane Library were searched for articles related to drug PK and LSG from inception to July 2021. Moreover, literature concerning postoperative physiological conditions in the gastrointestinal tract, such as gastric pH, gastric emptying, and small bowel transit time, etc., which may affect the PK profile of drug products was also reviewed. EXPERT OPINION Although LSG is classified as having restrictive property without malabsorptive bypass, postoperative changes in gastrointestinal physiology and subsequent weight loss may also lead to increased, decreased or unaltered drug exposure levels. General monitoring on drug efficacy or safety using biomarkers is proposed. In addition, therapeutic drug monitoring for those drugs when it is applicable and available is recommended to ensure efficient drug dosing and avoid adverse effects. Further research into many individual drugs are warranted.

Abstract
In the XXI century obesity has become one of the most demanding epidemiological threats worldwide. At the same time, bariatric surgery has established itself as an effective treatment for morbidly obese patients, with laparoscopic sleeve gastrectomy (LSG) emerging as the most popular bariatric procedure. This paper reviews the role of imaging studies of patients after LSG. Computed tomography is widely considered as the method of choice in detection of complications in early postoperative period. The dynamic character of upper gastrointestinal examination allows for the assessment of passage through the gastric remnant. The paper also discusses evaluation of the shape and volume of the gastric remnant assessed by imaging studies.

Abstract
INTRODUCTION The volume of the gastric reservoir (VGR) after sleeve gastrectomy influences weight loss in the short-term, but long-term results are scarce. The aim was to analyze the correlation between the VGR and weight loss at 5 years of follow-up. METHODS It is a prospective observational study of 50 patients undergoing sleeve gastrectomy (SG) from February 2009 to December 2013. An upper gastrointestinal series was performed at 1 month and at 1 and 5 years after surgery. A composite formula was used for VGR estimation. Weight loss-related data included the following: body mass index (BMI), percentage of excess weight loss (%EWL), and percentage of excess BMI loss (%EBMIL) at 1 month and at 1 and 5 years. Uni- and multivariate analyses were carried out to determine other factors that might influence long-term weight loss results. RESULTS The %EWL at 1 year was 74.5(63.8-86) vs. 55.5(47-74.3) at 5 years (p < 0.001). The VGR 1 month after surgery was 114.9 (90.5-168.3) mL. The VGR increased from 216.7 (155.1-278.6) to 367.5 (273-560.3) mL (p < 0.001) at 1 and 5 years. Although a significant inverse correlation was observed between VGR and BMI, %EWL, and %EBMIL at 1 year, it disappeared at 5 years. In the multivariate analysis, the main factor to predict worse weight results at 5 years was a pre-surgical BMI ≥ 50 kg/m2. CONCLUSION The VGR increased progressively during the study period. Although an inverse relationship between VGR and weight was found at 1 year, this correlation did not remain at 5 years. A preoperative BMI ≥ 50 kg/m2 is the main predictive factor of poor weight outcomes.

Abstract
PURPOSE Several factors including preoperative stomach capacity and sleeve volume impact weight loss after laparoscopic sleeve gastrectomy (LSG). We aimed at measuring these volumes using multidetector computed tomography (MDCT) gastrography and correlating them with postoperative weight losses. MATERIALS AND METHODS Morbidly obese patients prepared for LSG during 2018 were included in the study. MDCT gastrography was performed 1 week before, 6 and 12 months after LSG. Preoperative gastric volume and postoperative sleeve volumes were measured. Correlation with preoperative BMI and postoperative %TWL was performed. The change in sleeve volume at 6 and 12 months was assessed. RESULTS A total of 98 patients (62 F) were included. Mean preoperative BMI was47 ± 7 kg/m2. Follow-up was achieved in 89 patients (91%) and 82 patients (83%) at 6 and 12 months, respectively. Mean %TWL was 24 ± 3 and 32.8 ± 3 at 6 and 12 months, respectively (p < 0.05). Preoperative gastric volume ranged from 800 to 1800 ml (mean ± SD, 1310 ± 307) and dropped significantly to range from 140 to 170 ml (158 ± 9) and from 165 to 210 ml (181 ± 12) at 6 and 12 months postoperatively, respectively. Pouch was not significantly dilated at 12 vs. 6 months postoperatively. Preoperative gastric volume was significantly correlated with preoperative BMI (p = 0.006*) but not with postoperative weight losses. Correlation between postoperative pouch volumes and weight losses at 6 and 12 months postoperatively showed no significance. CONCLUSION Sleeve pouch is significantly smaller than preoperative stomach, but not significantly correlated to weight loss. Restriction is an important, but not the only factor controlling weight loss after LSG.

Abstract
The purpose of this study was to conduct a literature review to examine micronutrient deficiencies in laparoscopic sleeve gastrectomy. We conducted a literature review using PubMed and Cochrane databases to examine micronutrient deficiencies in SG patients in order to identify trends and find consistency in recommendations. Seventeen articles were identified that met the defined criteria. Iron, vitamin B12 and vitamin D were the primary micronutrients evaluated. Results demonstrate the need for consistent iron and B12 supplementation, in addition to a multivitamin, while vitamin D supplementation may not be necessary. Additional prospective studies to establish a clearer picture of micronutrient deficiencies post-SG are needed.

Abstract
BACKGROUND Postoperative sleeve volume (SV) is a key factor in evaluating the results of laparoscopic sleeve gastrectomy (LSG). An objective measurement of SV was obtained with 3-dimensional computed tomographic (3DCT) reconstruction. Several studies have compared SV with percent excess weight loss (%EWL), identifying an inverse relationship. We hypothesized that gastric capacity is one of the factors responsible for weight loss after LSG. OBJECTIVES Outcomes of the study were the analysis of the inverse correlation between SV and weight loss (%EWL and body mass index) at the 12-month follow-up, and evaluation of SV in the group with %EWL >50%. In addition, the failure rate was quantified in the SV >180 mL group. MATERIALS AND METHODS This is a prospective study with the collection of data. All patients who received LSG from January to December 2017 were evaluated. Computed tomography was performed on the upper abdomen at 12 months postoperatively to measure the SV using a standardized technique involving gastric distension. RESULTS A total of 42 patients were considered for 3DCT evaluation at the 12-month follow-up. A significant linear inverse relation was reported between SV and %EWL (P<0.05); a similar trend, without significant results, was reported for body mass index loss. The entire cohort was subdivided according to %EWL. A %EWL<50% presented a significantly higher mean SV (P<0.01) than %EWL >50%. SV >180 mL was powerful in predicting abnormal gastric distension. Over this value, %EWL was lower than that in the remaining group (P<0.05, 31.9% vs. 51.8%). CONCLUSIONS Our results confirmed a direct relation between SV and %EWL. Objective evaluation of gastric compliance obtained with 3DCT should be used intensively for LSG.

Abstract
OBJECTIVE To study the relationship between the amount of surgery-induced gastric volume reduction and long-term weight loss and glucose tolerance. BACKGROUND DATA Vertical sleeve gastrectomy (VSG) has recently surpassed gastric bypass to become the most popular surgical intervention to induce sustained weight loss. Besides inducing significant weight loss, VSG also improves glucose tolerance. Although no clear correlation has been observed between the size of the residual stomach and sustained weight loss, this begs the question whether less aggressive gastric volume reduction may provide sufficient efficacy when weight loss is not the major goal of the surgical intervention. METHODS A series of strategies to reduce gastric volume were developed and tested in Long Evans male rats, namely: VSG, Fundal (F)-Resection, Gastric Sleeve Plication (GSP), Fundal-Plication, and Fundal-Constrained. RESULTS All surgical interventions resulted in a reduction of gastric volume relative to sham, but none of the interventions were as effective as the VSG. Gastric volume was linearly correlated to increased gastric emptying rate as well as increased GLP-1 response. Overall, cumulative food intake was the strongest correlate to weight loss and was logarithmically related to gastric volume. Regression modeling revealed a nonlinear inverse relation between body weight reduction and gastric volume, confirming that VSG is the only effective long-term weight loss strategy among the experimental operations tested. CONCLUSIONS The data suggest a minimum threshold volume of the residual stomach that is necessary to induce sustained weight loss. Although all gastric volume interventions increased the GLP-1 response, none of the interventions, except VSG, significantly improved glucose tolerance. In conclusion, if weight loss is the primary goal of surgical intervention, significant volume reduction is required, and this most likely requires excising gastric tissue.

Abstract
OBJECTIVE Some patients fail to maintain weight loss after bariatric surgery. Weight regain (WR) disturbs the patients due to possible reappearance of obesity-related comorbidities. This study aimed to assess WR 5 years after laparoscopic sleeve gastrectomy (LSG). PATIENTS AND METHODS This retrospective study included 100 adults who underwent LGS. The percentage of excess weight loss (%EWL) was recorded. WR was defined as an increase of at least 10% of the lowest postoperative weight. Patients with WR were subjected to CT gastric volumety. Eating behavior was assessed by the Three-Factor Eating Questionnaire-Revised 18-Items (TFEQ-R18). RESULTS Preoperative comorbidities improved in 89.5% of the patients. Twenty-five females (32.5%) got pregnant within 3 years after surgery. Age, maximum weight loss, and uncontrolled and emotional eating scales of the TFEQ-R18 were independently affecting %EWL. Also, pregnancy negatively affected %EWL. Fourteen patients regain weight: 11 females and three males. CT volumetry of the 14 patients showed a median stomach volume of 515 mL (range 172-1066 mL). CT estimated gastric volume was negatively correlated with % EWL (r = - 0.674, p = 0.008). Patients who developed WR were significantly older (p = 0.006), with lower maximum weight loss, and having higher scores of uncontrolled and emotional eating scales of TFEQ-R18. CONCLUSION Medium-term postsurgical weight regain and unsuccessful weight loss in patients who had undergone LSG is associated with older age, maladaptive eating behavior, larger residual stomach, and pregnancy.

Abstract
Among the bariatric surgery community, it has recently emerged the idea of a possible association between resected gastric volume (RGV) and weight loss after laparoscopic sleeve gastrectomy (LSG). If the size of the sleeve depends on the bougie caliber, the resected volume of the stomach remains something which is not possible to standardize. The aim of the study was to investigate a possible relationship between RGV and weight loss after LSG. We developed a mathematical method to calculate the RGV, based on the specimen size removed during LSG. Ninety-one patients (63 females and 28 males) affected by morbid obesity were included in the study. They underwent LSG between 2014 and 2016. Mean preoperative BMI was 45 ± 6.4. At 1 year after LSG, the mean BMI was 30 ± 5.3 and the EWL% was 65 ± 20.2. The statistical analysis of RGV, BMI, and EWL% at 1-year follow-up did not find any correlation between the volume of stomach removed and the weight loss after LSG. Further studies in the future should clarify the potential role of RGV during LSG. This trial is registered with ClinicalTrials.gov NCT03938025.

Abstract
BACKGROUND Sleeve gastrectomy (SG) is one of the most effective treatments for severe obesity, but weight regain after surgery is a challenging issue. The mechanism of postoperative weight relapse is barely understood because of the lack of long-term data. OBJECTIVES To review and synthesize current evidence related to factors that contribute to weight regain after SG. METHODS Whittemore and Knafl's integrative method guided the research. The databases PubMed, EMBASE, and CINAHL, as well as 2 selected journals, were searched through October 2018 to gather English-language journal articles on the potential predictors of post-SG weight regain among adult populations. Only articles with sample size ≥10 were included. A narrative synthesis was used to analyze the 17 studies included in the review. RESULTS In recent years there has been an upward trend in the published reports of SG on longer-term outcomes. After a review of 6863 records, 17 eligible studies were identified, reporting various definitions of weight regain and 3 main categories of predictors: surgical/anatomic factors, hormonal/metabolic imbalance, and behavioral/mood factors. The 17 studies used quantitative (n = 16) and qualitative methods (n = 1). CONCLUSION There is a dearth of available literature addressing predictors of weight regain after SG, and the inconsistency in the definition of regain limited the comparability between studies. Besides the surgical/anatomic factors that have been reported as significant predictors, other modifiable factors such as behavioral and psychosocial determinants need to be further investigated.

Abstract
PURPOSE To classify the shape of the remnant stomach after Billroth-I (B-I) reconstruction and evaluate the relationship between the shape of the remnant stomach and the postoperative clinical outcomes. METHODS One hundred and ninety-five consecutive patients with gastric cancer underwent distal gastrectomy with B-I reconstruction between May 2006 and October 2014. We retrospectively reviewed their medical records and radiological findings. Finally, the shapes of the remnant stomach of 150 patients were classified as either straight type (type A) or stagnant type (type B). The clinical outcomes were compared with respect to the types of remnant stomach. RESULTS The incidence of anastomotic leakage was significantly higher in the type A group than in the type B group (9.4 vs. 1.5%, p = 0.044). The body weight change ratio after surgery was significantly lower in the type B group than in the type A group [p = 0.0068, two-way repeated measures analysis of variance (ANOVA)], while the serum albumin levels showed marginally significant improvement in the type B group compared with the type A group (p = 0.0542, two-way repeated measures ANOVA). CONCLUSION The shape of the remnant stomach after distal gastrectomy with B-I reconstruction might influence the degree of anastomotic leakage and long-term nutritional status.

Abstract
INTRODUCTION Laparoscopic sleeve gastrectomy is one of the most common techniques in bariatric surgery, but there is no consensus on the optimal distance from the pylorus to start the gastric transection. The aim of this study is to determine the differences in gastric emptying, gastric distension and metabolic response between two starting distances. MATERIAL AND METHODS This is a prospective randomised study of 60 patients (30 patients with the section at 3 cm and 30 patients at 8 cm from the pylorus). We calculate at 6 and 12 months from surgery gastric emptying by scintigraphy (T1/2 min), gastric volume by CT scan (cc) and metabolic response by blood sample analysis (glucose, HbA1c, insulin, HOMA-IR, GLP-1, GIP and C-peptide). RESULTS Gastric emptying increases the speed significantly in both groups but is greater in the 3-cm group (p < 0.05). Dividing groups into type 2 diabetic patients and non-diabetic patients, the speed in non-diabetic patients is significantly higher for the 3-cm group. Residual volume increases significantly in both groups, and there are no differences between them. One year after surgery, there are significant improvements in the hyperinsulinaemia in the patients of the 3-cm group with respect to the 8-cm group, but only in diabetic patients. No differences between groups are found regarding changes in GLP-1 or GIP. CONCLUSIONS Gastric emptying is faster in patients with antrum resection. The distance does not influence the gastric emptying of diabetic patients. Other mechanisms may explain metabolic response besides GLP-1 and its association with improvements in diabetes via gastric emptying.

Abstract
INTRODUCTION AND PURPOSE Sleeve gastrectomy (SG) is gaining ground in the field of bariatric surgery. Data are scarce on its impact on esophagogastric physiology. Our aim was to evaluate the impact of SG on esophagogastric motility with high-resolution impedance manometry (HRIM) and to assess the usefulness of HRIM in patients with upper gastrointestinal (GI) symptoms after SG. METHODS A retrospective analysis of 53 cases of HRIM performed after SG was conducted. Upper GI symptoms at the time of HRIM were scored. HRIM was analyzed according to the Chicago classification v3.0. A special attention was devoted to the occurrence of increased intragastric pressure (IIGP) after water swallows and reflux episodes as detected with impedance. A measurement of sleeve volume and diameter was performed with CT scan in a subgroup of patients. RESULTS IIGP occurred very frequently in patients after SG (77 %) and was not associated with any upper GI symptoms, specific esophageal manometric profile, or impedance reflux. Impedance reflux episodes were also frequently observed after SG (52 %): they were significantly associated with gastroesophageal reflux (GER) symptoms and ineffective esophageal motility. The sleeve volume and diameters were also significantly smaller in patients with impedance reflux episodes (p < 0.01). CONCLUSION SG significantly modified esophagogastric motility. IIGP is frequent, not correlated to symptoms, and should be regarded as a HRIM marker of SG. Impedance reflux episodes were also frequent, associated with GER symptoms and esophageal dysmotility. HRIM may thus have a clinical impact on the management of patients with upper GI symptoms after SG.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is a relatively new surgical technique for the treatment of morbid obesity. It is unclear whether the volume of the gastric remnant can expand after surgery as a result of intraluminal pressure maintained over time. If this were the case, the increased volume could affect weight loss and the improvement in comorbidities. This study aims to assess the evolution of residual gastric volume (RGV) during the first year after LSG and its relationship with weight loss. MATERIAL AND METHODS We conducted a prospective study of 112 patients who underwent LSG from February 2009 to December 2013. In order to measure the RGV after surgery, all patients were evaluated radiologically by an esophagogastroduodenal (EGD) transit at 1 and 12 postoperative months. RESULTS All patients showed a significant reduction in BMI compared with the preoperative measurement (33.48 ± 5.78 vs. 50.54 ± 6.69 kg/m2; p < 0.001). Increased RGV was observed when comparing the results obtained by EGD transit at 1 (68.39 ± 25.89 cm3) and 12 postoperative months (122.58 ± 38.76 cm3; p < 0.001). There was no association between increase in gastric volume and weight loss at 1-year follow-up (r = 0.01; p = 0.910). CONCLUSIONS The volume of the gastric remnant increased significantly during the first year after LSG. However, this increase was not associated with weight loss. Further prospective research with longer follow-up periods is needed to confirm or contrast the present results.

Abstract
BACKGROUND The relation between the resected gastric volume and the weight loss after laparoscopic sleeve gastrectomy appears conflicting in the literature. Both the residual and the resected volumes represent the total gastric volume, and if the weight loss is related to one of the two volumes, it should be related to the other. While some reports indicate that the weight loss is related to the resected gastric volume, others state that the weight loss is not related to the residual volume. The aim is to investigate the influence of the resected gastric volume on the weight loss after surgery. METHODS The study included 287 consecutive patients. Gastrectomy was performed encroaching over a 38-Fr calibrating tube all the way to the angle of His. Filling volume of the resected stomach, with tap water, was measured. Patients were analyzed into group 1 with BMI ≤50 kg/m(2) and group 2 >50 kg/m(2). RESULTS Females represented 74 % of cases. Mean age was 32.9 ± 9.5 years; preoperative BMI = 48.7 ± 7.9 kg/m(2). The mean resected gastric volume was 1525 ± 408 ml, and it was significantly lower in females compared to that in males (1443 ± 311 vs 1824 ± 502 ml, p < 0.001). Data were analyzed in two groups: group 1 with BMI ≤5050 kg/m(2) and group 2 >50 kg/m(2). Both groups were similar in preoperative BMI (p = 0.399) and excess weight percent (EW%) (p = 0.33). Group 2 had a resected gastric volume (1663 ± 424.7 ml) greater than that of group 1 (1440 ± 347 ml; p < 0.001). The percentage of excess weight loss (EWL%) was 57.9 ± 14.5 % at 6 months (62.7 ± 13.5 % vs 48.34 ± 11.29 %, p < 0.001), 77 ± 19 % at 12 months (84 ± 19.6 % vs 68 ± 14.2 %, p = 0.001), 76.6 ± 7.4 % at 18 months (79.7 ± 4.8 vs 74.7 ± 8.2 %, p = 0.5), and 75.8 ± 11.5 % at 24 months (81.7 ± 11.17 vs 70 ± 11 %, p = 0.8) (group 1 vs group 2, respectively). At 12 months, 86 % patients achieved more than 50 % EWL% (100 % of group 1 vs 60 % of group 2). Preoperative BMI correlated with resected gastric volume (r = 0.239, p = 0.004). In multiple regression, the initial BMI was a predictor of EWL% at 6 and 12 months (r partial = -0.65, p < 0.0001) while the resected gastric volume was not. CONCLUSIONS The resected gastric volume is related to the total gastric volume when the technique is standardized and the residual volume is calibrated using a consistent technique. It is not in itself a predictor of weight loss, but it is related to the initial BMI which predicts the weight loss.

Abstract
OBJECTIVES The success of longitudinal sleeve gastrectomy (LSG) is perceived as being potentially limited by dilatation of the remaining gastric tube during the follow-up. The aim of this prospective study was to determine the incidence and the characteristics of sleeve dilatation during the first post-operative year. MATERIALS AND METHODS Gastric volumetry using 3D gastric computed tomography with gas expansion was performed in 54 successive subjects who underwent an LSG for morbid obesity at 3 and 12 months following surgery. Total gastric volume, volume of the gastric tube and the antrum, and diameter of the gastric tube were assessed after multiplanar reconstructions. An increase of at least 25 % of the total gastric volume was considered as sleeve dilatation. Percentage of excess BMI loss (%EBMIL) and daily caloric intakes were recorded during the first 18 months. RESULTS Sixty-one percent of the subjects experienced sleeve dilatation 1 year after surgery. The gastric tube was mainly involved in the sleeve dilatation process (+91 %). Sleeve dilatation occurred especially in subjects with smaller total gastric volume at baseline (189 vs 236 ml, p = 0.02). Daily caloric intake was similar between the groups at each point of the follow-up. No difference concerning %EBMIL was observed between the groups during the 18 months of follow-up. CONCLUSIONS Sleeve dilatation occurred in more than 50 % of the patients. Dilatation was not necessarily linked to an increase of daily caloric intake and insufficient weight loss during the first 18 months following surgery. Small LSG at baseline is at higher risk of dilatation.

Abstract
Introduction. Laparoscopic Sleeve Gastrectomy (SG) is considered as successful if the percentage of Excess Body Mass Index Loss (% EBMIL) remains constant over 50% with long-term follow-up. The aim of this study was to evaluate whether early % EBMIL was predictive of success after SG. Methods. This retrospective study included patients who had SG with two years of follow-up. Patients had follow-up appointments at 3 (M3), 6, 12, and 24 months (M24). Data as weight and Body Mass Index (BMI) were collected systematically. We estimated the % EBMIL necessary to establish a correlation between M3 and M24 compared to % EBMIL speeds and calculated a limit value of % EBMIL predictive of success. Results. Data at operative time, M3, and M24 were available for 128 patients. Pearson test showed a correlation between % EBMIL at M3 and that at M24 (r = 0.74; p < 0.0001). % EBMIL speed between surgery and M3 (p = 0.0011) was significant but not between M3 and M24. A linear regression analysis proved that % EBMIL over 20.1% at M3 (p < 0.0001) predicted a final % EBMIL over 50%. Conclusions. % EBMIL at M3 after SG is correlated with % EBMIL in the long term. % EBMIL speed was significant in the first 3 months. % EBMIL over 20.1% at M3 leads to the success of SG.

Abstract
PURPOSE To evaluate the feasibility of post-operative CT gastrography for volumetry of the remnant stomach in gastric cancer patients treated with distal gastrectomy. METHODS CT gastrography was performed with oral administration of effervescent granules in 35 gastric cancer patients who underwent distal gastrectomy. Two readers independently rated the degree of gastric distension on a four-point scale, one (near-total collapse) to four (well distended) and measured the volume of remnant stomach using either 3D or 2D volumetry. The inter-volumetry agreements between the 2D and 3D methods and the interobserver agreements between readers 1 and 2 were assessed by intraclass correlation coefficients (ICCs) and Bland-Altman plots. RESULTS The mean score of gastric distension was 3.4 ± 0.6 points and 3.4 ± 0.7 points from readers 1 and 2, respectively. We regarded CT images scored with 3-4 points as a technical success for reliable CT volumetry, which achieved a rate of 91.4% (32/35). For the inter-volumetry agreements between 3D and 2D volumetry, the ICCs were 0.9778 and 0.9814 from readers 1 and 2, respectively. The interobserver agreement between readers 1 and 2 was also excellent, with ICCs of 0.9961 and 0.9876 for 2D and 3D volumetry, respectively. On Bland-Altman plots, the means of differences between any pairs of volumetry measurements ranged from -31.1 to 3.2 cm(3), which may be an acceptable range of measurement variability. CONCLUSIONS Post-operative CT gastrography is feasible in patients treated with distal gastrectomy. Both 2D and 3D volumetry methods are comparable in measuring the remnant stomach volume.

Abstract
BACKGROUND Rapid gastric emptying has been proposed to justify the increase in glucagon-like polypeptide-1 (GLP-1) after laparoscopic sleeve gastrectomy (LSG). OBJECTIVES To assess gastric emptying changes after LSG and their relationship with GLP-1 secretion. SETTING San Salvatore Hospital general surgery unit, University of L'Aquila, Italy. METHODS 52 patients underwent gastric emptying scintigraphy for liquid and solid foods, before and 3 months after LSG. Twenty-six patients were in the liquid group (L group) and the remaining in the solid group (S group). We evaluated the half time of gastric emptying (T1/2) and percentage of gastric retention (%GR) at 15, 30, and 60 minutes for liquids and at 30, 60, 90, and 120 minutes for solids. GLP-1 plasma concentrations were measured in each group before and after LSG and related to %GR. Statistical analysis was performed by Χ2 test and Pearson correlation(r). RESULTS After surgery, T1/2 was significantly accelerated: 15.2±13 min and 33.5±18 min in the L group and S group, respectively (P<.05). In both groups, GLP-1 plasma concentrations were increased at each blood sampling time: 2.91±2.9 pg/mL, 3.06±3.1 pg/mL and 3.21±2.6 pg/mL at 15, 30, and 60 minutes, respectively, (P<.05) for L group and 2.72±1.5 pg/mL, 2.89±2.1 pg/mL, 2.93±1.8 pg/mL, and 2.95±1.9 pg/mL at 30, 60, 90, and 120 minutes, respectively, (P< .05) for the S group. After LSG, GLP-1 and %GR presented a negative linear correlation (r) at each blood sampling time in both groups. CONCLUSION The rapid gastric emptying 3 months after LSG upregulates the production of GLP-1 in the distal bowel. Further studies are needed to confirm these findings.

Abstract
BACKGROUND Attempts are being made in recent years to replace open surgery with endoscopic techniques in some obese patients when medical treatment fails, as they are considered to be less-invasive procedures. To date, there is little scientific evidence regarding their effectiveness. CLINICAL CASES The cases are reported of 2 patients who attended our surgery looking for an effective bariatric surgical treatment after failed endoscopic sleeve gastroplasty. CONCLUSIONS Laparoscopic sleeve gastrectomy after failure of an endoscopic technique does not offer great variation from the standard technique.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy is a surgical procedure for the treatment of morbid obesity. However, there are still controversies regarding its efficiency in terms of weight reduction and incidence of complications. In this prospective study, the experience is presented of a referral centre for the treatment of morbid obesity with laparoscopic sleeve gastrectomy. MATERIAL AND METHODS A prospective study on 73 patients subjected to laparoscopic sleeve gastrectomy from February 2009 to September 2013. Patients were followed-up for a period of 12 months, evaluating the development of complications, reduction of gastric volume, and the weight loss associated with the surgery, as well as their impact on the improvement of comorbidities present at beginning of the study. RESULTS There was a statistically a significantly reduction between the preoperative body mass index (BMI) and the BMI at 12 months after laparoscopic sleeve gastrectomy (p < 0.001), despite there being an increase in the gastric volume during follow-up, measured at one month and 12 months after surgery (p < 0.001). Five patients (6.85%) had complications, with none of them serious and with no deaths in the whole series. CONCLUSIONS Laparoscopic sleeve gastrectomy is a safe and effective technique for the treatment of morbid obesity. Its use is associated with a significant reduction in the presence of comorbidities associated with obesity. Multicentre studies with a longer period of monitoring are required to confirm the efficacy and safety of this surgical technique.

Abstract
Bariatric surgery is an effective and enduring treatment for obesity. Sleeve gastrectomy (SG) has emerged as an increasingly prevalent surgical intervention. Further investigation is required to determine optimal standardization of SG. Data were collected prospectively for 64 patients who underwent a laparoscopic vertical SG between December 2010 and February 2013 at a single academic institution. Demographic, intraoperative, and postoperative (postop) data were collected for all patients including weighing each resected stomach. The total resected gastric weight varied widely. Preoperatively, patients in the upper tercile for resected gastric weight were more likely to be male (lower 10%, middle 23%, upper 52%, P = 0.006) and had greater initial weights (lower 255.9%, middle 245.1%, upper 280.0%, P = 0.019). The resected gastric weight (g) varied by tercile (mean of all, 131.24 ± 39.8; lower, 93.9 ± 10.9; middle, 127.4 ± 11.7; upper 172.7 ± 37.9, P = 0.000). Patients were followed for 1-year postop with follow-up data for 94 per cent (60/64) of participants. Per cent excess weight loss (EWL) was obtained at three, six, and 12 months postop. At 12 months, there was a trend toward increased per cent EWL in the upper tercile (lower 61.1%, middle 54.1%, upper 90.5%, P = 0.057). In conclusion, while the amount of gastric sleeve resected can vary, this study shows that intraoperative assessment of resected sleeve weight can help evaluate adequacy of resection. Improved 12-month per cent EWL in patients with greater resected tissue demonstrate potentially improved outcomes.

Relationship between gastric pouch and weight loss after laparoscopic sleeve gastrectomy. Surg Endosc 2015; 30:1559-63.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is considered safe and effective even as conversion procedure after primary bariatric operations. The correlation between gastric pouch volumes and patients weight loss remains unclear. METHODS To assess a correlation between the gastric remnant size and the weight loss, we reviewed 49 consecutive barium swallow UGS performed at our institute from August 2012 through May 2014 in LSG patients with symptoms and/or unsatisfactory weight loss. The anteroposterior (AP), laterolateral (LL) and vertical (CC) diameters of the gastric pouch were measured to calculate the volume by the formula of the ellipsoid (AP × LL × CC × 0.5). Patients were divided in two groups: group 1 without gastric pouch (n = 36) and group 2 with gastric pouch (n = 13). Correlation between pouch volume and weight loss data was calculated with t Student's and Fisher tests to compare the percent excess body mass index (BMI) and percent excess body mass loss (EBL) between two groups, and P < 0.05 was considered statistically significant. RESULTS The mean percent EBL was 26.54 ± 11.02 and 27.12 ± 12.35 kg/m(2) in groups with and without pouch, respectively. The mean volume of the pouch after LSG was 17.13 ± 21.56 mm(3). Pouch volume, when present, was not significantly correlated to weight loss (P = 0.88 95% CI, CL 19.88-33.20 group 2; CL 22.94-31.30 group 1). CONCLUSIONS No statistical correlation was found between the volume of the gastric pouch and weight loss (percent EBL) after LSG in symptomatic or with unsatisfactory weight loss patients.
