Objective: The objective of this study was to examine the use and outcomes of perioperative anticoagulation (AC) in obese patients with a known history of venous thromboembolism event (VTE)., Method: A retrospective review of a prospective database for patients with a VTE history undergoing bariatric and general surgery at a single center (1/2008-12/2017) was performed. Factors assessed included demographics, surgical details, and outcomes., Results: Sixty-five patients underwent 76 procedures: 46 females (71%); mean age 51 years (range 26-73), mean weight 284 pounds (range 110-558), mean body mass index 45 (range 19-87). Comorbidities include hypertension (60%), gastroesophageal reflux disease (54%), osteoarthritis (49%), obstructive sleep apnea (45%), and diabetes (37%). Operations: 22 general surgeries (29%), 20 sleeve gastrectomies (26%), 12 revisions/conversions (16%), 12 Roux-en-Y gastric bypasses (16%), and 10 gastric bands (13%). Modalities: 67% laparoscopic, 28% robotic, and 5% open. Twenty-two patients (34%) had a pre-operative inferior vena cava filter placed with no complications. The mean length of stay was 4.4 days (range 1-31). Complications: seven 30-day readmissions (9%), one 30-day reoperation (1%), and two 90-day VTEs (3%). Thirty-day readmissions: four for inability to tolerate PO, two for small bowel obstruction, and one for symptomatic anastomotic ulcer., Conclusions: In our patients, post-operative AC could be started without an increased risk of bleeding in patients with a history of VTE undergoing bariatric surgery., (Copyright: © 2024 Permanyer.)

Introduction: Perioperative outcomes of bariatric surgery in patients with super super obesity (SSO) (BMI ≥ 60 kg/m 2 ) merit further investigation., Methods: A retrospective review was conducted of patients with SSO who underwent surgery from Jun 2005 through Jun 2018 at a Metabolic and Bariatric Surgery Center of Excellence. Quantitative demographic data was summarized using descriptive statistics; categorical variables were compared using Fisher's exact test., Results: Two hundred fourteen procedures were performed, of which 208 were eligible for inclusion. Majority were female (65.4%). The mean age and BMI was 43 (17-68 years) and 65.9 kg/m 2 (60 95 kg/m 2 ), respectively. Comorbidities included: obstructive sleep apnea (74%), hypertension (59%), gastro-esophageal reflux disease (43%), osteoarthritis (41%), and diabetes mellitus (30%). Surgical approach: 97 Roux-en-Y gastric bypasses (46%), 88 laparoscopic sleeve gastrectomies (42%), and 23 adjustable gastric bands (11%). Additional subset included: primary (87%), conversion (7.7%), and revision (5.3%); majority being laparoscopic (75%) and robotic (24%). Complications via Clavien-Dindo classification: one Grade I, one Grade II, three Grade IIIa, three Grade IIIb, and three Grade IVa. Thirty-day events: 11 complications (5.3%; one leak [0.5%], one deep vein thrombosis [0.5%]), six re-admissions (3%), four re-operations (2%): repair of staple-line leak, repair of incisional hernia, uterine dilation and curettage, and cholecystectomy. No mortalities occurred. Complications occurred in 14.8% of conversion/revision cases, 3.9% in primary cases ( p  = 0.0395) with no difference observed between laparoscopic (4.5%) and robotic (6.1%) modalities ( p  =   0.7051)., Conclusion: Bariatric surgery is feasible in patients with SSO. Revision procedures may increase risk of operative complications., Competing Interests: Conflicts of Interest: The authors declare no conflict of interest., (© 2021 by SLS, Society of Laparoscopic & Robotic Surgeons.)
