Background:
Portomesenteric vein thrombosis (PMVT) is a rare but severe complication after laparoscopic bariatric surgery, with potentially serious consequences. We aimed to describe the incidence, clinical features, management, outcome, and midterm follow-up in patients with PMVT after laparoscopic sleeve gastrectomy (LSG).
Methods:
This retrospective and descriptive study included patients who underwent LSG between November 2009 and July 2015 and developed PMVT. The following data were analyzed: age, gender, body mass index (BMI), thrombosis risk factors, surgical technique, thromboembolic prophylaxis, primary surgery outcomes, clinical features, treatment, thrombophilia testing results, and follow-up findings, including imaging and endoscopic findings.
Results:
A total of 1236 patients underwent LSG, and 5 (0.4 %) developed PMVT. The mean age was 34.4 years, and 3 patients were women. The mean BMI was 38.5 kg/m2. Two patients had received hormonal contraceptive treatment. Four patients had a history of smoking. All of the patients received anticoagulant treatment, and none required surgery. The mean hospitalization duration was 7.6 days. Two patients showed complete recanalization. One patient showed portal cavernomatosis on delayed images. Two patients had a positive thrombophilia test. No portal hypertension endoscopic findings were observed.
Conclusions:
PMVT is a rare complication, for which smoking was identified as a predominant risk factor. Early diagnosis and prompt anticoagulant therapy could lead to a dramatic decrease in the incidence of intestinal infarction, mortality, and extrahepatic portal hypertension in the near future. However, careful follow-up is necessary to evaluate the impact of PMVT on long-term patient outcomes.
Insights
Portomesenteric vein thrombosis (PMVT) is a rare complication after laparoscopic sleeve gastrectomy (LSG). Early diagnosis and anticoagulant therapy are crucial for managing this condition and preventing severe outcomes.
Area of Science:
- Gastroenterology
- Vascular Surgery
- Bariatric Surgery
Background:
- Portomesenteric vein thrombosis (PMVT) is a rare but serious complication following laparoscopic bariatric surgery.
- Laparoscopic sleeve gastrectomy (LSG) is an increasingly common bariatric procedure.
- Understanding PMVT after LSG is crucial for patient outcomes.
Purpose of the Study:
- To determine the incidence of PMVT after LSG.
- To describe the clinical features, management, and outcomes of PMVT in LSG patients.
- To evaluate midterm follow-up findings in patients who developed PMVT post-LSG.
Main Methods:
- Retrospective and descriptive study design.
- Inclusion of patients who underwent LSG between November 2009 and July 2015 and subsequently developed PMVT.
- Analysis of patient demographics, risk factors, surgical details, treatment, and follow-up data.
Main Results:
- A total of 1236 patients underwent LSG, with 5 (0.4%) developing PMVT.
- Smoking was identified as a predominant risk factor.
- All patients received anticoagulant therapy, with two showing complete recanalization and one developing portal cavernomatosis.
Conclusions:
- PMVT is a rare but significant complication of LSG, with smoking as a key risk factor.
- Prompt diagnosis and anticoagulant treatment are vital to reduce complications like intestinal infarction and mortality.
- Long-term follow-up is essential to assess the full impact of PMVT on patient health.
