Introduction
Hemorrhagic complications after laparoscopic sleeve gastrectomy (LSG) are among the most common adverse events. The last 10 min of LSG are essential in terms of hemostasis. Aim: To assess the blood pressure profile in the last 10 min of LSG in patients who experienced hemorrhagic complications after laparoscopic sleeve gastrectomy.

Material and methods
We performed a retrospective case-control study. The medical records of 867 patients who underwent primary LSG were analyzed. Cases were defined as patients who required surgical revision due to hemorrhagic complications within 72 h. Controls were matched (1 : 1) with cases by age, body mass index, gender, staple line reinforcement, comorbidities and surgeon’s experience. Comparison of the last three intraoperative blood pressure measurements at the end of surgery was made.

Results
The bleeding rate was 3.0%. A total of 24 subjects (12 matched pairs) were included in the study. Cases had statistically significant increased mean arterial blood pressure (mm Hg) 5 min before the end of surgery (87.8 ±11.9 vs. 79.4 ±8.8 mm Hg, p = 0.049) and at the end of surgery (89.2 ±11.7 vs. 77.5 ±11.8 mm Hg, p = 0.011). Higher diastolic blood pressure measurements were observed 5 min before the end (72.1 ±10.7 vs. 62.8 ±8.1 mm Hg, p = 0.023) and at the end of surgery (74.2 ±10.0 vs. 60.8 ±11.2 mm Hg, p = 0.004).

Conclusions
Compared with closely matched control subjects, patients with HC after LSG have increased mean arterial pressure in the last 5 min of surgery. This phenomenon has not been reported in the literature before.
