Abstract
BACKGROUND Obesity treatment includes less invasive procedures such as gastric plication (GP) surgery; however, its effects on gastrointestinal (GI) motility parameters are underestimated. We aimed to verify the metabolic and gastrointestinal effects of GP surgery in the rat obesity model. METHODS A high-fat diet-induced obesity was used. Animals were allocated to four experimental groups: control sham (n = 6); control GP (n = 10); obese sham (n = 6); and obese GP (n = 10). Nutritional and murinometric parameters, gastric motility, glucose tolerance, histopathology, fat depots, leptin, and lipoproteins levels were evaluated 30 days after surgery. Data were analyzed by ANOVA followed by post Tukey or Kruskal-Wallis test followed by Dunn's multiple comparisons test. KEY RESULTS Gastric plication decreased leptin levels, feed efficiency, and body weight gain. GP does not improve lipid profile in obese animals and however, ameliorates glucose tolerance in control and obese rats. GP did not improve the gastric emptying time or normalize the frequency of contractions disturbed by obesity. Surgery provides a remodeling process in the mucosa and muscularis mucosa layers, evidenced by leukocyte infiltration mainly in the mucosa layer. CONCLUSIONS & INFERENCES Our study revealed the influence of the gastrointestinal tract on obesity is underestimated with pieces of evidence pointing out its important role as a target for surgical treatment.

New intragastric sleeve technique reduces adipose tissue in pig experimental model: tomographic study. Sci Rep 2020; 10:18122. [PMID: 33093489 PMCID: PMC7581739 DOI: 10.1038/s41598-020-74846-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2019] [Accepted: 08/23/2020] [Indexed: 11/08/2022] Open
Abstract
In order to implement a new bariatric surgery technique, we verify the efficacy of intragastric sleeve to reduce weight gain and subcutaneous adipose tissue (SAT). Animals were divided into two groups: G1 (single-port intragastric sleeve) and G2 (sham group). The stomach was surgically reduced by single-port intragastric sutures to fo a gastric sleeve. Animals were submitted to computer tomography (CT) before the surgical procedure and after 18 weeks. Images were analyzed and measurements of the thickness of SAT, depth and width of the longissimus dorsi muscle and the rib eye area were made. Body weight and CT measurements were analyzed using the GLM PROC. The correlation coefficients were calculated among weight, moments and measures. There was a significant difference in weight gain, in which G1 had an average of 42.803 ± 3.206 kg, lower than G2 (45.966 ± 4.767 kg). The mean values for SAT and muscle measurements differed significantly between groups, in which G1 achieved the lowest values. All variables had significant correlations and high magnitude. Intragastric sleeve surgery induced a significant decrease of SAT. The new intragastric sleeve technique is feasible, safe and effective, mainly in reducing fat deposition, making it an important alternative in bariatric surgical treatment.

New technique of intragastric sleeve: viability and survival in a pig model. AN ACAD BRAS CIENC 2020; 90:3075-3080.

Abstract
Developing a less invasive, practical and cost-effective operative technique for obesity treatment represents a pressing need for our society. In this way, intragastric single port sleeve by endoplication was tested in six pigs during 18 weeks. Celiotomy was performed with animal placed in dorsal decubitus position. Single port gastrostomy was performed and double tobacco pouch sutures were made in fundic region, making a gastric sleeve. At the end, stomach layers and skin were closed in a conventional manner. Means and the standard deviations of surgical time were calculated. The procedure was simple and all animals survived; there were no significant blood loss and no intra and postoperative complications. The procedure was fast (67.4 minutes). The technique has the advantage of not requiring the use of mechanical sutures, making it less costly. The innovation of this procedure was the use of a single port gastrostomy device to perform an intraluminal sleeve. What made this technique less invasive were the use of a single port, nonmanipulation of the stomach intra-abdominally, ease of execution and no need of pneumoperitoneum. The new technique is acceptable and has reproducible viability, had a short procedure time without intra and postoperative complications.
