Introduction Evisceration is a frequent consequence after performing midline laparotomies (ML) in urgent abdominal surgeries. The aim of this study was to compare and evaluate the results obtained after the introduction of barbed sutures in abdominal wall closure. Materials and methods We performed a retrospective analysis of patients undergoing emergency surgery in our hospital following a midline laparotomy approach in the last 5 years. Preoperative variables were compared between both groups and related to early surgical wound complications, depending on the type of abdominal wall closure performed. Results 222 patients underwent surgery (Polydioxanone (P); 128; Barbed (B); 94) after ruling out exclusion factors such as neuromuscular disease, recent abdominal surgeries and whose follow-up had been lost. There were no significant differences between the two groups in terms of preoperative baseline characteristics or associated comorbidities. Furthermore, there were no statistically significant differences in type of surgery performed; the most frequent was small bowel obstruction. After data analysis, no differences were found in terms of hospital stay (P; 7.43 days vs B; 6.05 days, p=0.421) or mortality (P; 3.125% vs B; 4.25, p=0.655). Concerning immediate complications, there were no differences regarding surgical wound infection (P; 18.75% vs B; 10.63%, p=0.061) and seroma (P; 3.125% vs B; 2.12, p=0.651). Evisceration rates turned out to be more frequent in the polydioxanone group (P; 20.31% vs B; 8.51%, p=0.016). Conclusions The use of barbed sutures reduced the incidence of evisceration, therefore it can be considered as recommended sutures for aponeurotic closure in emergent ML.

Aim Spigelian hernias are rare. Surgical treatment is often recommended. Different minimally invasive techniques are available by means of intraperitoneal or extraperitoneal mesh placement, either by IPOM, transabdominal preperitoneal (TAPP) or total extraperitoneal (TEP) approach. TEP approach is seldom reported in the literature. We present a short series of TEP repair of Spigelian hernias. Materials and Methods Between February and October 2022, TEP repair was performed in two patients with unilateral Spigelian hernia, one case of bilateral hernia, and one combined unilateral Spigelian and inguinal hernia, ensuing the following technique. Preperitoneal access was achieved placing a contralateral 11mm trocar, a few centimetres above the umbilicus, posterior to the rectus muscle toward Retzius space. A 5mm trocar was placed suprapubic and another 11mm trocar at the flank. Working space is developed by blunt dissection. Spigelian hernia sac is dissected and reduced. At this point other inguinal or femoral hernias are explored, performing simultaneous repair if necessary. Sufficient preperitoneal space is ensured to allow correct overlap of a polypropylene self-gripping mesh, prior to closing the defect with barbed-polydioxanone suture. Results Median age was 72 years. Three cases were right hernias and two left, all diagnosed by imaging test due to symptoms. Latest discharge was 24 hours after surgery. No complications or recurrences were encountered at a median follow-up of 4 months. Conclusions Comparative studies between minimally invasive approaches of Spigelian hernias are scarce. In the presented experience, TEP approach proved to be an efficient and reproducible technique with favourable results.
