Purpose: Leakage of the gastric remnant after laparoscopic sleeve gastrectomy (LSG) represents an unpredictable, dreadful occurrence. Our aim was to assess whether routine postoperative CT scan is an effective tool for early prediction of leakage after LSG. Materials and Methods: From a prospectively acquired database, all consecutive patients who underwent LSG between January 2015 and December 2018 were identified; within this database, all patients who were evaluated with at least one contrast-enhanced CT scan within 48 h from surgery were enrolled in this retrospective study. The selected CT findings included twisting of the gastric remnant, perigastric air bubbles, and hematoma; the antral segment proximal from the pylorus to the first staple firing was also analyzed in terms of distance (StP, stapler to pylorus distance) and linearity (LI, linearity index). Results: After exclusions, 250 patients were included; 10 patients suffered from gastric leakage. Patients with perigastric hematoma and/or twisting of the distal part of the gastric remnant on routine postoperative CT scan were found to be more likely to develop leakage after LSG (p = 0.005 and p < 0.001, respectively). The mean StP was 45 ± 19.1 mm; the mean LI was 1.54 ± 0.4. Patients with subsequent development of leakage had significantly lower StP (26.7 ± 12.5 mm vs. 45.9 ± 18.9 mm; p = 0.001) and LI values (1.16 ± 0.11 vs. 1.55 ± 0.39; p = 0.002). Conclusion: Routine postoperative CT scan after LSG permits early stratification of leakage risk, thus providing an actual aid for patients’ management.

Abstract

Purpose: Leakage of the gastric remnant after laparoscopic sleeve gastrectomy (LSG) represents an unpredictable, dreadful occurrence. Our aim was to assess whether routine postoperative CT scan is an effective tool for early prediction of leakage after LSG. Materials and Methods: From a prospectively acquired database, all consecutive patients who underwent LSG between January 2015 and December 2018 were identified; within this database, all patients who were evaluated with at least one contrast-enhanced CT scan within 48 h from surgery were enrolled in this retrospective study. The selected CT findings included twisting of the gastric remnant, perigastric air bubbles, and hematoma; the antral segment proximal from the pylorus to the first staple firing was also analyzed in terms of distance (StP, stapler to pylorus distance) and linearity (LI, linearity index). Results: After exclusions, 250 patients were included; 10 patients suffered from gastric leakage. Patients with perigastric hematoma and/or twisting of the distal part of the gastric remnant on routine postoperative CT scan were found to be more likely to develop leakage after LSG (p = 0.005 and p < 0.001, respectively). The mean StP was 45 ± 19.1 mm; the mean LI was 1.54 ± 0.4. Patients with subsequent development of leakage had significantly lower StP (26.7 ± 12.5 mm vs. 45.9 ± 18.9 mm; p = 0.001) and LI values (1.16 ± 0.11 vs. 1.55 ± 0.39; p = 0.002). Conclusion: Routine postoperative CT scan after LSG permits early stratification of leakage risk, thus providing an actual aid for patients’ management.
