The Relationship Between Tachycardia After Laparoscopic Sleeve Gastrectomy and the Development of Postoperative Complications

Is Routine Post-operative Biological Laboratory Assessment Necessary After Sleeve Gastrectomy?

BACKGROUND

Incidence of post-operative complications after sleeve gastrectomy (SG) is low. However, the early identification of these complications remains crucial. Here, we report the impact of routine laboratory monitoring for the early diagnosis of complications after SG.

MATERIAL AND METHODS

From January 2018 to December 2019, all consecutive patients who underwent primary SG (n = 457) were included. This was a comparative study of patients undergoing primary SG. Patients were divided into two groups: one group with routine laboratory monitoring performed at postoperative day (POD) 1 and 3 (LAB group) and another group without routine laboratory monitoring (control group). The study's primary endpoint was the overall impact of routine laboratory monitoring. The secondary endpoints were evaluation of patients with complications.

RESULTS

The population in the two groups were similar in term of demographic and intra-operative data. There was a statistical difference between the two groups in term of length of stay (5.7 days in the LAB group and 3.5 days in the control group (p < 0.001)). There were 19 complications (6.0%) in the LAB group and 5 complications in the control group (3.5%) (p = 0.25). A cut-off C-reactive protein level of 46.3 mg/l was found to be significant (p = 0.006). In the LAB group, 9 patients (2.9%) required readmission vs. three patients (2.0%) in the control group (p = 0.62).

CONCLUSION

The interest of routine laboratory monitoring after SG seems limited. Routine laboratory monitoring alone is not associated with earlier diagnosis of complications. This routine monitoring is associated with an increase of stay in hospital.
