Laparoscopic repair for SH is preferred over the open approach as it is associated with a low morbidity rate and a short hospital stay. In our experience, TEP technique is safe and effective in laparoscopic SH repair.

Introduction Spigelian hernia is a rare lateral ventral hernia traditionally repaired through open incision with extensive dissection. Three laparoscopic techniques have been reported in the literature: intraperitoneal onlay mesh (IPOM), transabdominal preperitoneal (TAPP), and total extraperitoneal (TEP). TEP is less popular than the other approaches. We evaluated TEP's safety and effectiveness and compared different laparoscopic techniques. Methods All patients with Spigelian hernia who had undergone extended TEP (eTEP) repair with mesh in our center from January 2007 to February 2020 were studied. A three‐port technique with a preperitoneal space created by telescope at the midline was adopted. A systematic review on laparoscopic mesh repair was performed by searching for “Spigelian hernia” and “laparoscopic” from 1999 to 2019 in the MEDLINE database. Results Seven patients underwent eTEP repair for Spigelian hernia. Five presented with abdominal mass and underwent preoperative imaging. Two were diagnosed incidentally during TEP for inguinal hernia. The mean operative duration was 65 minutes (range, 40‐93 minutes). There were no open conversions or intraoperative complications. The mean length of hospital stay was 1.4 days (range, 1‐3 days). The mean follow‐up period was 44.3 months. One patient developed seroma. There was no recurrence or chronic pain. We identified 197 laparoscopic mesh repairs reported in 41 articles. IPOM (n = 91) was the most popular approach, followed by TAPP (n = 70) and TEP (n = 36). Laparoscopic mesh repair of Spigelian hernia is safe and offers excellent outcomes. Conclusion We found the eTEP approach safe and effective for Spigelian hernia repair. IPOM, TAPP, and TEP are comparable.

Background: Peritoneal dialysis (PD) is the first-line renal replacement therapy for end-stage renal failure patients in Hong Kong. Abdominal wall hernia is a common mechanical complication of PD, and early surgical repair has been advocated to reduce complications. This study aims to review the outcomes of tension-free mesh repair of inguinal hernia in PD patients. Methods: All PD patients who underwent elective repair of inguinal hernia from 2009 to 2015 were identified from a single centre for retrospective analysis. Primary outcomes included surgical complications, perioperative dialysis technique and recurrence. Results: Twenty-one patients with a total of 26 inguinal hernia repairs were included in this 7-year retrospective study. All were males, and the mean age was 68 ± 10 years. Diabetic nephropathy ( n = 9, 42.9%) and glomerulonephritis ( n = 7, 33.3%) were the two most common causes of renal failure. All hernias were detected after the initiation of PD, and the mean duration of PD to hernia detection was 16 months (range 1–65 months). Lichtenstein open mesh repair was performed in all patients. Complications included seroma ( n = 3, 11.5%) and ischaemic orchitis ( n = 1, 3.8%). There were no mesh infection or recurrence. Twenty patients (95.2%) received intermittent peritoneal dialysis post-operatively and returned to continuous ambulatory PD in 15 to 30 days. Only one patient (4.8%) required bridging haemodialysis due to Tenckhoff catheter blockage. Conclusions: Tension-free mesh repair is associated with low morbidity and low recurrence rates in PD patients. Timely management and close collaboration with renal physicians are essential to continue PD after repair.

The laparoscopic approach is comparable to the open approach in the repair of small paraumbilical hernias. For small paraumbilical hernias, we recommend that laparoscopic repair be reserved for obese patients or those with suspected multiple hernial defects.
