PurposeLaparoscopic inguinal hernia repair has facilitated early mobilization. Management of post-operative pain is paramount in these day case procedures. The aim of this study was to compare laparoscopic-assisted transversus abdominis plane (TAP) block with periportal local anaesthetic infiltration in managing post-operative pain.MethodsA double-blind, randomized controlled trial was conducted with patients undergoing elective laparoscopic inguinal hernia repair (January 2016–October 2017). The intervention group received laparoscopic-assisted TAP block with 30 ml 0.25% Bupivacaine. The control group received 15ml of 0.5% Bupivacaine at the periportal sites. Primary outcome measure was assessment of post-operative pain scores using numerical rating on visual analogue scale (VAS) at rest and on coughing at 3 h. Efficacy of TAP block was assessed as reduction in mean pain scores in the order of 2 points using the VAS.Results60 (57 males and 3 females) were enrolled; 30 patients were randomized to each group. Patient demographics, anaesthetic and surgical times were similar in both groups. Mean pain scores were significantly reduced in the intervention group at 3 (3.1 vs 1.1 p < 0.001) and 6 h (4.1 vs 1.7 p < 0.001) at rest and on coughing at 3 (4.8 vs 2.1 p < 0.001) and 6 h (5.4 vs 3.0 p < 0.001). Patient satisfaction was higher (8.0 vs 6.8 p < 0.001) and rescue analgesic requirements (169.4vs 71.3 p < 0.001) lower in the intervention group.ConclusionsThis analysis has demonstrated the therapeutic benefit of laparoscopic-assisted TAP block in initial post-operative pain management for patients undergoing elective laparoscopic inguinal hernia repair.

Acquired abdominal intercostal hernia (AAIH) is an infrequent occurrence whereby intra-abdominal contents herniate into intercostal space directly from the peritoneal cavity through an acquired defect in the abdominal wall musculature and fascia. These hernias are difficult to diagnose and should always be suspected when a chest wall swelling occur after major or minor trauma. Surgical repair is warranted in symptomatic patients. The majority of AAIHs are repaired through an open approach using tension-free mesh, with significant recurrence risk. Recently, laparoscopic and robot-assisted repairs have been proposed. We discuss a 49-year-old man presented through outpatient setting with a 5-year history of ongoing left subcostal discomfort and a reducible lump. His history included a workplace accident 5 years ago. Contrast-enhanced abdominal CT confirmed AAIH with omentum herniation into the sac. A successful laparoscopic repair with intraperitoneal onlay mesh technique using composite mesh was performed.
