Study of ECHELON ENDOPATH(TM) Staple Line Reinforcement

Inclusion Criteria: * Primary procedure (gastric or lung resection) where the ECHELON SLR is planned to be used for reinforcement of staple lines per the IFU in either a or b: 1. Gastric procedures limited to laparoscopic gastric resection, robotic laparoscopic gastric resection, partial gastrectomy, gastric wedge resection, subtotal gastrectomy, laparoscopic Roux-en-Y gastric bypass, and robotic laparoscopic gastric bypass; or 2. Lung resection procedures that include lobectomy, segmentectomy or wedge resection, and lung volume reduction surgery, and may be video assisted thoracic surgery (VATS) or open procedures; * Willingness to give consent and comply with all study-related evaluations and visit schedule; and * At least 18 years of age. Exclusion Criteria: \- Preoperative: 1. Physical or psychological condition which would impair study participation; 2. Body mass index (BMI) ≥ 46.0 kg/m2; 3. The procedure is a revision/reoperation for the same indication or same anatomical location; 4. A procedure where extended wound or organ support is required; 5. Any medical condition that the investigator deems could impact inflammatory or immune response; 6. Concurrent treatment with medications that the investigator deems could have influence on wound healing; 7. History of hypersensitivity to polyglactin (Vicryl®), Polydioxanone (PDO or PDS), or hypersensitivity to related products (cross-allergy); or 8. Enrollment in a concurrent interventional clinical study that could impact the study endpoints. * Intraoperative: 9. Per surgeon discretion, presence of adhesions that could lead to an increased risk of leak occurrence at a different location than the staple line.
