Effectiveness and safety of n-butyl-2-cyanoacrylate medical adhesive for noninvasive patch fixation in laparoscopic inguinal hernia repair
ABSTRACT BACKGROUND: Our purpose was to compare the recurrence rate and other clinical outcomes of laparoscopic (LS) transabdominal preperitoneal (TAPP) inguinal hernia repair using n-butyl-2-cyanoacrylate (NBCA) for mesh fixation with those of no mesh fixation and mesh fixation with titanium spiral tacks (ST). METHODS: The medical records of patients who received LS TAPP inguinal hernia repair between 2009 and 2012 at our institution were reviewed. Patients were included if the received LS TAPP with either no mesh fixation, mesh fixation with NBCA only, fixation with ST only, or fixation with NBCA + ST. Outcome measures were operation time, postoperative length of stay, visual analogue scale (VAS) pain score 24 h after surgery, postoperative complications, and hernia recurrence. RESULTS: A total of 1,027 TAPP cases were included. In 552 cases, meshes were fixed with NBCA only, in 89 cases only ST were used, in 47 cases ST and NBCA were used, and in 339 cases meshes were not fixed. The groups were comparable with respect to demographic and clinical characteristics. No surgical complications occurred in any group. VAS pain scores were significantly lower in the nonfixation and NBCA only groups (1.4 ± 0.6 and 1.3 ± 0.6, respectively) than in the ST and NBCA + ST groups (2.2 ± 0.9 and 2.2 ± 0.7, respectively; P = 0.001). The mean follow-up duration was ~19 months. At the final follow-up, no wound infections or hernia recurrences had occurred in any of the groups. No occurrence of chronic pain was noted in the nonfixation and NBCA only groups, whereas two cases (2.2%) were noted in the ST group and one case (2.1%) in the NBCA + ST group (P = 0.005). CONCLUSIONS: The use of NBCA medical adhesive for noninvasive patch fixation in laparoscopic hernia repair (TAPP) is effective and safe.

ABSTRACT: Liver retraction is critical in single-incision laparoscopic upper abdominal surgery. Several techniques have been reported. Some need an additional port, whereas others are complicated and time-consuming. n-Butyl-2-cyanoacrylate (NBCA) glue was applied to bond the left lateral lobe of the liver to the diaphragm in different single-incision laparoscopic upper abdominal procedures. Liver adhesion time and duration of operation were recorded, and preoperative and postoperative liver function tests carried out. All procedures were completed successfully without additional ports or special instruments. The technique provided adequate workspace and a clear view. Mean liver adhesion time was 1·5 min. The maximum operating time was 310 min. Levels of alanine and aspartate aminotransferases were raised on day 1 after surgery but had returned to normal by day 7. Creating adhesion between the left lateral lobe of the liver and the diaphragm using NBCA glue is a simple, safe and effective way of achieving liver retraction in single-incision laparoscopic upper abdominal surgery.British Journal of Surgery 04/2014; 101(5).
