“…Pilone et al evaluated their patients with 3D CT scans and lower RGV was significantly associated with a higher %EWL in the postoperative 12th month (31.9% vs. 51.8%, p <0.05) [ 18 ]. Doğan et al [ 19 ] used intraoperative CO 2 inflation to measure the RGV and it did not show any significant relationship with weight loss in the postoperative 6th, 12th, and 24th months. In our study, we used the 3D CT scan to measure the RGV, and it was statistically significant with weight loss.…”

Background We aim to assess the effects of gastric posterior fixation with fibrin sealant in laparoscopic sleeve gastrectomy in aspects of 12th-month body mass index and gastric volume. Methods The patients who underwent laparoscopic sleeve gastrectomy between January 2019 and February 2021 were divided into two groups preoperatively. The first 75 patients were appointed to the posterior fixation group, and the second 75 were to the control group. Changes in gastric volume and body mass index were assessed in the postoperative 12th month. Results There were 110 patients in the final analysis. Fifty-four patients had posterior fixation, and 56 had only laparoscopic sleeve gastrectomy. The posterior fixation group was superior in terms of total weight loss rate (39.1% vs. 34.5%, p<0.001) and less gastric volume increase rate (39.8% vs. 164.7%, p<0.001) in the postoperative 12th month. Conclusion Our study suggests that posterior fixation with fibrin sealant in laparoscopic sleeve gastrectomy is a promising method for preventing weight regain and creating a need for revision surgery.

“…Based on radiological studies, the most common are biplanar barium or water-soluble iodine-contrasted images, whereas other studies have demonstrated that the resultant sleeve to be a complex geometrical shape with a cylindrical proximal component (gastric body) as well as a truncated cone (antrum). Others utilized gastric scintigraphy for these purposes [15].…”

“…Using MDCT with post-processing volumetry study is considered an accurate method to analyze the volume/shape of the gastric pouch following bariatric surgery [16]. Moreover, it has been utilized to detect the correlation between the volume of residual gastric as well as EWL following sleeve gastrectomy [15].…”

Laparoscopic 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.

“…Several factors associated with surgical technique have been studied, including volume of resected stomach, gastric remnant volume (GRV), and the size of a bougie used to calibrate gastric sleeve (GS) diameter [5][6][7][8]. GRV may be assessed either intraoperatively, by recording the amount of fluid used to expand the gastric remnant during methylene blue leak test, or with imaging studies: upper gastrointestinal study (UGI) or computed tomography (CT) [9][10][11][12][13][14][15][16][17][18].…”

Radiographic Measurement of Gastric Remnant Volume After Laparoscopic Sleeve Gastrectomy: Assessment of Reproducibility and Correlation with Weight Loss

et al. 2021

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. Graphical Abstract
