Abstract
Introduction: Staple-line bleeding and gastric leakage are the most serious complications of laparoscopic sleeve gastrectomy (LSG). Reinforcement of the staple line is reported to be a method to reduce these complications rates, but the question of which method is preferable is a matter of controversy in the literature. In this study, we compared different staple-line reinforcement methods to assess their efficiency in preventing staple-line bleeding and leakage. Materials and Methods: Two hundred patients eligible for LSG were enrolled in the study and randomized into five groups based on the reinforcement method used during surgery: no reinforcement, oversewing using 3-0 polydioxanone (PDS) suture, oversewing using 4-0 barbed absorbable closure device (V-Lock), fibrin sealant glue, and buttress material. Intraoperative and postoperative complications were recorded and analyzed. Differences were considered statistically significant for Pā<ā.05. Results: The no-reinforcement group showed higher bleeding rates (20%), although only 2.5% of the patients required reintervention. All groups using staple-line reinforcement showed better outcomes in bleeding rates (Pā<ā.05). No statistically significant differences were observed among the groups in terms of the leakage rate, reintervention rate, intraoperative complications, and operative times. Conclusion: The reinforcement of the staple line decreased the bleeding rate in sleeve gastrectomy but did not affect the gastric leakage rate.

Abstract
BACKGROUND Various systems exist for prosthesis fixation in hernia repair. These techniques vary in terms of postoperative complications and pain. This study compares prosthesis fixation techniques employed in laparoscopic transabdominal preperitoneal (TAPP) hernioplasty using a visual analog scale (VAS) to quantify postoperative pain. METHODS Patients (n = 600) underwent TAPP inguinal hernia repair in a randomized prospective study. Prostheses were fixed with Protak (Tyco, Norwalk, Conn), (Group A; n = 150), EndoANCHOR (Ethicon Endo-Surgery, Inc. , Cincinnati, Ohio) (Group B; n = 150), EMS (Ethicon Endo-Surgery, Inc. ) (Group C; n = 150), or Tissucol (Baxter Healthcare, Milan, Italy) (Group D; n = 150). Patients were interviewed up to 1 month post-intervention. Post-operative pain was evaluated on a 0- to 10-point VAS (0 = no pain, 10 = maximum pain). Morbidity, length of stay, return to work and recurrence were also assessed. RESULTS Overall, 803 hernias were treated: 397 patients (66. 2%) had unilateral hernias and 203 (33. 8%) had bilateral hernias. In total, 96 (12%) hernias were recurrences and 707 (88%) were primary. Postoperative pain ranged from VAS1 to VAS2 (mild pain) between 12 hours and 72 hours with Tissucol (Group D), and it was higher in Groups A-C: Maxima ranged from VAS4 (moderate pain) with EMS to VAS7 (severe pain) with Protak at 48-hour follow-up. Significant differences in length of stay occurred, no recurrence or conversion rates were observed among groups, and morbidity was generally lower with Tissucol. Patients in Group D (Tissucol) also returned to work sooner than did Groups A-C (Protak, EndoANCHOR, and EMS). CONCLUSIONS We found differences in postoperative pain among different laparoscopic TAPP prosthesis fixation methods. The use of the biocompatible fibrin sealant Tissucol seems to reduce significantly postoperative pain, complications, and resumption to work times compared with other systems.
