Abstract Aim To obtain tension-free closure for giant incisional hernia repair, anterior or posterior component separation (ACS, PCS) is often performed. In extreme patients, ACS and PCS may be combined. The aim of this study was to assess the additional medialization after simultaneous ACS and PCS. Material and Methods Fresh-frozen post mortem human specimens were used. Both sides of the abdominal wall were subjected to retro-rectus dissection (Rives-Stoppa), ACS and PCS, the order in which the component separation techniques (CST) were performed was reversed for the contralateral side. Medialization was measured at three reference points. Results ACS provided most medialization for the anterior rectus sheath, PCS provided most medialization for the posterior rectus sheath. After combined CST total median medialization ranged between 5.8 and 9.2 cm for the anterior rectus sheath, and between 10.1 and 14.2 cm for the posterior rectus sheath (depending on the level on the abdomen). For the anterior rectus sheath, additional PCS after ACS provided 15% to 16%, and additional ACS after PCS provided 32% to 38% of the total medialization after combined CST. For the posterior rectus sheath, additional PCS after ACS provided 50% to 59%, and additional ACS after PCS provided 11% to 17% of the total medialization after combined CST. Retro-rectus dissection alone contributed up to 41% of maximum obtainable medialization. Conclusions ACS provided most medialization of the anterior rectus sheath and PCS provided most medialization of the posterior rectus sheath. Combined CST provides marginal additional medialization, clinical use of this technique should be carefully balanced against additional risks.

Mesh Technique

Background: Chevrel’s technique provides tensionfree repair of midline incisional hernia, but wide skin and subcutaneous dissection increases rate of complications. Here, we evaluate the double mesh modification of Chevrel’s technique in midline incisional hernia repair. Methods: 22 patients with midline incisional hernia underwent double mesh modification of Chevrel’s technique. After excision of hernial sac with minimal dissection of the skin and subcutaneous tissue, the anterior rectus sheath is incised on both sides to create medial flaps that are sutured toeach other. Both recti abdominis muscles were dissected off the posterior rectus sheath, opening the retrorectus space. Prolene mesh was fixed in the retrorectus space with prolene sutures, and tailored to cover the bare area of anterior surface of both recti muscles and fixed to the lateral flaps of the anterior rectus sheath with interrupted prolene sutures. Results: We observed no recurrences, no skin necrosis, two cases of seroma, one case of superficial wound infection and one case of temporarychronic pain. Conclusion: Double mesh modification of Chevrel technique is an efficient method for treatment of midline incisional hernia, with minimal surgical site occurrences.

Midline Closure

Abstract Background The complications of intraperitoneal onlay mesh repair for ventral hernia has favored sublay mesh placement like open Rives–Stoppa repair (ORS). There was a need for low-cost laparoscopic trans-abdominal repair using a polypropylene mesh (PPM) with sublay, midline closure and addition of posterior component separation (PCS) by transversus abdominis release (TAR). Methods The techniques used three or six operating ports with triangulation. After adhesiolysis, a transverse incision was made on the peritoneum (P) and posterior rectus sheath (PRS). The retromuscular space was developed by raising a P-PRS flap. Midline closure was performed with No. 1 polydioxanone, and a PPM was placed in sublay, followed by closure of defect and P-PRS incision. For large hernias with divarication; myo-fascial medialization using PCS-TAR aided low-tension midline closure. Results Eighty-nine patients were operated from 2010 to 2019, 26 primary ventral; 63 incisional; and 22 recurrent hernias. Of the primary, 21 were umbilical, one Spigelian and four epigastric hernias. The incisional group had 57 patients with lower midline scars (C-section 25, open tubal ligation 15, abdominal hysterectomy 17), five lateral (appendicectomy), one post-laparotomy. The mean age, male/female sex ratio and BMI were 41.23 years, 1:10.1 and 29.2 kg/m2, respectively. Mean defect and mesh area were 110 cm2 and 392 cm2. Mean operating time was 192 min. Conversion to open, mesh infection and recurrence rates were 3.4%, 1.1% and 5.62%. Conclusion Laparoscopic TARM with PPM in sublay avoids mesh–bowel contact. It provides midline closure and PCS-TAR within the same port geometry with results comparable with ORS.

Sublay Repair

Abstract Aim We describe in detail the step by step technique of the first case of TES repair at our institution. Methods We selected the case of a M2W3L3 hernia associated to xipho-umbilical diastasis recti in a young woman symptomatic for a progressively worsening back pain and local bulky sensation. Results The intervention is started directly with a suprapubic transverse incision of 2.5 cm and a circumferential, atraumatic retraction is inserted after a small incision of the anterior rectus sheath. Blunt dissection is further continued through this access by luxating the underlying rectus muscles to separate the preperitoneal space below the arcuate line. The pneumo-preperitoneum is then inducted through this port. Laparoscopic dissection allows for enlargement of the avascular space laterally and then two 5-mm trocars are placed on the bilateral aspects of rectus muscles. By means of a lap bipolar dissector the edge of posterior rectus sheath are incised from the arcuate line following the diastasis laterally up to the subxiphoid space. The Rives plane is recovered without opening of the linea alba. After reduction of the M2 hernia both the posterior sheath and the diastatic anterior fascia are sutured with a running long-resorbable 2/0 barbed suture. Polyvinylidene fluoride (PVDF) mesh fixed with the use of an hystoacrilic glue. Conclusion Minimally invasive extraperitoneal repair of small/medium hernia defects of the linea alba is gaining wide acceptance. Concomitant presence of rectum diastasis recti seems to be the ideal indication to approach the learning curve of such a technically demanding procedure

Abstract Aim “COVID has been a great challenge for Hospitals around the world. At our surgical department a new protocol of TAP block was designed and implemented in our laparoscopic incisional ventral hernia repairs, to allow these patients to be operated in ambulatory regime, without compromising pain control and the outcomes. In this video we aim to present the technique for the Laparoscopic-guided TAP Block during a Laparoscopic IPOM Plus ventral hernia repair.” Material and Methods “We implemented this protocol in July 2020 and since then, we performed 18 TAP block in laparoscopic incisional hernia repairs, laparoscopic guided by the Surgeon or ultrasound-guided by the Anesthesiologist. In this case, the video reports to a Laparoscopic IPOM Plus incisional hernia repair performed on a 54-year-old patient, male, with obesity, arterial hypertension and dyslipidemia. He had a 6 centimeter incisional hernia post-colorectal surgery in 2013.” Results “As detailed in the video, we show all the steps to perform a TAP block under laparoscopic direct visualization” Conclusions “TAP block can be performed by the Surgeon, with direct visualization at the beginning of the laparoscopic procedure.”
