- Zagazig University
- Brief Summary
This study included patients who were admitted to investigator's center to do laparoscopic sleeve gastrectomy . Cases were collected in the period from December 2019 to December 2020. Sample size was 84 patients divided into 2 equal groups . Group 1: included 42 patients who were subjected to distal mesogastric fixation after laparoscopic sleeve gastrectomy. Group 2: included 42 patients who were subjected to laparoscopic sleeve gastrectomy alone without distal mesogastric fixation.
- Detailed Description
Laparoscopic sleeve gastrectomy is one of weight loss operations and widely performed all over the world . although its widely performed ,it has serious complications like leakage and bleeding . The proposed etiology behind leakage after laparoscopic sleeve gastrectomy may be the axial rotation of the stomach owing to loss of abdominal ligament fixation along the greater curvature of the stomach . The mechanism of increased intra-gastric pressure due to axial gastric rotation may put a lot of stress on the staple lines with increased incidence of leakage. Other complications may occur such as vomiting, food intolerance or persistent reflux.
Objectives:
To assess the effect of distal mesogastric fixation after laparoscopic sleeve gastrectomy to minimize gastric axial rotation and subsequent leakage and other related complications.
Patients and methods:
investigators included all patients who were subjected to laparoscopic sleeve gastrectomy at investigators' center between December 2019 to December 2020. The study was approved by the research and Ethics committee of our university and performed in accordance with the code of ethics of the world medical association (Declaration of Helsinki) for studies involving humans. A written informed consent was obtained from all participants.
Sample size The sample size was calculated using open Epi program using the following data ; confidence interval 95% , power of test 80% , the percent of patients without leak after LSG was 66.6% while after new technique expected to be 95% , odd ratio 9.5% and ratio between two group 1:1; so the calculated sample size was 72 patients , taking into consideration 20% drop outs so the final sample size will be 84 patients divided into 2 equal groups . Group 1: included 42 patients who were subjected to distal mesogastric fixation after laparoscopic sleeve gastrectomy. Group 2: included 42 patients who were subjected to laparoscopic sleeve gastrectomy alone without distal mesogastric fixation.
Patients who had no contraindication for laparoscopic surgery (such as patients with no history of abdominal operations), good general condition with American society of anesthesiology (ASA) I \& II, and patients with body mass index above 35 were included. investigators excluded patients who had bad general condition (ASA ≥3), patients with gastro esophageal reflux or hiatal hernia.
Perioperative measures:
In this prospective randomized control trials , all patients were subjected to the followings: patients were selected by randomization method , Full history taking , Complete physical examination , laboratory investigations ( complete blood picture , liver and kidney functions , coagulation profile ) , radiological investigations ( chest x- ray , CT with oral and I.V contrast ) \& patients were subjected to upper GI endoscopy.
Surgical techniques :
investigators performed traditional laparoscopic sleeve gastrectomy then investigators fixed the greater omentum \& mesocolon that were cut during gastrectomy to the remaining gstric pouch along the new greater curvature as high as possible along the stable line then we plicated the remaining staple line till angle of His. (the greater omentum \& mesocolon not reach this part of staple line) , so the remaining gastric pouch remained tension free and was returned to original position and this may prevent the axial gastric rotation as in figures .
Follow up after surgery and discharge from the hospital:
investigators examined the patients clinically, made routine laboratory investigations , made follow up CT with oral and I.V contrast in first week after the operation if suspected leakage \& patients were subjected to upper GI endoscopy in first week after the operation if suspected leakage. The patients were followed up for one week, two weeks and one month, 6months post operatively.
Statistical analysis:
The collected data were analyzed by computer using Statistical Package of Social Services version 22 (SPSS), Data were represented in tables and graphs, Continuous Quantitative variables e.g. age were expressed as the mean ± SD \& (range), and categorical qualitative variables were expressed as absolute frequencies (number) \& relative frequencies (percentage).
Suitable statistical tests of significance were used after checked for normality. Categorical data were cross tabulated and analyzed by the Chi-square test or Fisher's Exact Test; Continuous data were evaluated by student t- test. The results were considered statistically significant when the significant probability was less than 0.05 (P \< 0.05). P-value \< 0.001 was considered highly statistically significant (HS), and P-value ≥ 0.05 was considered statistically insignificant (NS).
