Placement of retrievable inferior vena cava filters (rIVCF) may be beneficial in high-risk morbidly obese patients undergoing bariatric procedures. Patients with a previous history of venous thromboembolism (VTE) are at high risk for postoperative deep venous thrombosis (DVT) and pulmonary embolism (PE). ⋯ We observed a 21% incidence of recurrent DVT and 15% incidence of thrombus in the IVCF, yet no PE occurred. IVCF retrieval was successful in 70% with one complication. Concurrent IVCF placement is safe, feasible, and an effective preventative measure in high-risk morbidly obese patients. We recommend the use of rIVCFs in conjunction with standard VTE prophylaxis in this patient population.

Laparoscopy-assisted distal gastrectomy (LADG) is gaining wider acceptance for treating early gastric cancer (EGC). However, many gastric surgeons are still reluctant to perform LADG, mainly because this procedure entails a considerable learning curve. We aimed to evaluate the technical feasibility and short-term outcomes of performing LADG by a single experienced gastric surgeon who initially had no experience with laparoscopic surgery as compared with open distal gastrectomy (ODG). ⋯ Although LADG was more time consuming than ODG, it was a feasible, safe procedure that accomplished the oncological requirements. Postoperative morbidity of LADG was similar to that of ODG, and LADG led to faster postoperative recovery. However, LADG should be performed carefully to prevent unexpected complications, especially during the early learning period.

Laparoscopic hepatectomy (LH) is increasingly used. However, the safety and outcomes of LH have yet to be elucidated. The risk of venous gas embolism is increased during liver parenchymal transection. This risk may be increased with positive pressure carbon dioxide (CO(2)) pneumoperitoneum (PP). This may be exacerbated further when low central venous pressure (CVP) anesthesia is used to minimize hemorrhage during liver resection. ⋯ Carbon dioxide embolism during LH occurs frequently. Clinically, this finding appears to be nominal, but care must be taken when dissection around large veins is performed, and awareness by the surgical and anesthesiology teams of potential venous air embolism is essential. Further evaluation of this phenomenon is required.
