The Effects of the Staple Line Reinforcement Procedures on Gastrointestinal Symptoms and Its Early Results in Sleeve Gastrectomy

Omentopexy versus no omentopexy in sleeve gastrectomy: an updated systematic review and meta-analysis

Laparoscopic sleeve gastrectomy with omentopexy (O-LSG) has been compared to laparoscopic sleeve gastrectomy with no-omentopexy (NO-LSG) in terms of postoperative outcomes and one-year anthropometric results. This systematic review with meta-analysis aimed to compare the utility of omentopexy in sleeve gastrectomy. We performed a systematic review with meta-analysis according to PRISMA 2020 and AMSTAR 2 guidelines. We included studies that systematically searched electronic databases and compared the O-LSG with the NO-LSG conducted through 1st March 2023. The bibliographic research yielded 13 eligible studies. These studies included 5514 patients. The O-LSG is associated with lower leakage (OR = 0.22; 95% CI [0.08, 0.55], p = 0.001), bleeding (OR = 0.33; 95% CI [0.19, 0.57], p < 0.0001), vomiting (OR = 0.50; 95% CI [0.28, 0.89], p = 0.02), twist (OR = 0.09; 95% CI [0.02, 0.39], p = 0.001), and shorter hospital stay (MD = - 0.33; 95% CI [- 0.61, - 0.05], p = 0.02) compared with NO-LSG. The O-LSG is associated with longer operative time (MD = 8.15; 95% CI [3.65, 12.64], p = 0.0004) than the NO-LSG. There were no differences between the two groups in terms of postoperative GERD (OR = 0.53; 95% CI [0.27, 1.02], p = 0.06), readmission (OR = 0.60; 95% CI [0.27, 1.37], p = 0.23), and one-year total weight loss (MD = 2.06; 95% CI [- 1.53, 5.65], p = 0.26). In the subgroup analysis including only RCTs, postoperative GERD was lower in the O-LSG (OR = 0.26; 95% CI [0.11, 0.63], p = 0.003). Our systematic review and meta-analysis concluded that omentopexy in sleeve gastrectomy is feasible and safe It reduced leakage, bleeding, and twist. It probably increased the operative time. It may reduce vomiting, GERD, and hospital stay. We don't know if it led to an additional readmission rate or one-year total weight loss.Registration The protocol was registered in PROSPERO with the ID CRD42022336790.

Does Omentopexy Make a Difference in Laparoscopic Sleeve Gastrectomy for Obesity Treatment? A Systematic Review and Meta-Analysis

This systematic review and meta-analysis aimed to evaluate the comparative outcomes of laparoscopic sleeve gastrectomy with omentopexy (LSGO) versus conventional laparoscopic sleeve gastrectomy (LSG) for obesity treatment. A systematic online search was conducted using the available online databases, and Revman software was used for data analysis. Twenty-two eligible comparative studies were included (n = 9,321). LSGO showed a significantly lower rate of gastric leak (P = 0.0001), staple line bleeding (P = 0.00001), and gastric torsion (P = 0.002) in comparison to the LSG group. Operative time was significantly shorter in the LSG group (P = 0.00001); however, the length of hospital stay was in favour of the LSGO (P = 0.00001). Compared to LSG without omentopexy, LSG with omentopexy provides a significantly lower rate of postoperative complications and shorter LOS at the expense of operative time.

A comparative study between staple line reinforcement during laparoscopic sleeve gastrectomy and no reinforcement: an Egyptian experience

BACKGROUND

Laparoscopic sleeve gastrectomy (LSG) has become an increasingly popular bariatric procedure. LSG still conveys some risks, including early staple line complications such as bleeding and leaks. It has been proposed that staple line complications can be reduced by staple line reinforcement (SLR). This study aimed to compare the short-term efficacy and safety of the SLR during LSG by oversewing versus no SLR in an Egyptian cohort over a period of 11 years.

PATIENTS AND METHODS

This is a retrospective study that analyzed data from patients undergoing LSG by the same surgeon over a period of 11 years. The patients' early postoperative complications were compared according to performing SLR.

RESULTS

The SLR group showed significantly longer surgery time (p = 0.021) and a lower rate of postoperative bleeding (p = 0.027). All leakage cases occurred in the non-SLR group (0.7% vs. 0.0%) without statistical significance (p = 0.212). The two mortality cases occurred in the non-SLR group. The LOS was comparable in the two groups (p = 0.289).

CONCLUSION

This study confirms the short-term benefits of SLR by oversewing during LSG in terms of a lower incidence of 30-day morbidity, particularly bleeding, and lower rates of reoperation, with a clinically questionable longer operation time.

Omentopexy/Gastropexy (OP/GP) Following Sleeve Gastrectomy Might be an Effective 2-in-1 Method (Reinforcement and Fixation): A Meta-Analysis of 14 Studies and a Call for Randomized Controlled Trials

BACKGROUND

Laparoscopic sleeve gastrectomy can lead to dangerous complications as leaks and hemorrhage. In addition, it can lead to gastric twist/torsion, prolonged postoperative nausea and vomiting (PONV), and de novo gastroesophageal reflux disease (GERD). We aimed to study the efficacy of omentopexy/gastropexy (OP/GP) in the prevention of these postoperative complications.

MATERIALS AND METHODS

PubMed and Google Scholar were queried in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data was analyzed using the Review Manager (RevMen) 5.4.1 software. Mantel-Haenszel statistical method and random effects analysis model were used in all meta-analyses. The odds ratio was used for dichotomous data. Subgroup analysis was done according to bougie size. Subgroup analysis according to the distance between the starting point of gastric transection and pylorus was not possible (limitation). Odds ratio and control event rate across studies were used to calculate the number needed to treat (NNT) with OP/GP for an additional beneficial outcome (prevention of adverse outcome) to occur.

RESULTS

The initial search identified 442 records; 371 were found irrelevant after screening and were excluded. The remaining 71 reports were retrieved and assessed for eligibility. An additional 57 reports were excluded following an in-depth assessment. The remaining 14 studies were included in this meta-analysis; 8 were nonrandomized studies (NRSs) while 6 were randomized controlled trials. Most studies originated from a single country (limitation). A statistically significant decrease in favor of OP/GP was observed for all outcomes (bleeding, leaks, gastric twist/torsion, prolonged PONV 1 month postoperatively, and postoperative de novo GERD). Data was consistent across studies (low I2 ), and subgroup analysis according to bougie size revealed no subgroup differences. However, this study had 3 limitations that does not allow for strong conclusions.

CONCLUSIONS

Although the current literature lacks strong scientific evidence, this study suggests that omentopexy/gastropexy (OP/GP) may offer protection against bleeding and leaks as a staple line reinforcement method, as well as against gastric twist/torsion, prolonged postoperative nausea and vomiting (PONV), and de novo gastroesophageal reflux disease (GERD) as a staple line fixation method. Therefore, it is worthwhile to proceed with large-scale, multicenter, randomized controlled trials to reevaluate our findings. Furthermore, conducting a comparison between OP/GP and other staple line reinforcement techniques would be beneficial.
