P037 TOTALLY ENDOSCOPIC SUBLAY REPAIR FOR DIASTASIS RECTI AND CONCOMITANT MIDLINE HERNIA: FIRST CASE VIDEO-REPORT

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

P045 MEDIALIZATION AFTER COMBINED ANTERIOR AND POSTERIOR COMPONENT SEPARATION IN GIANT INCISIONAL HERNIA SURGERY, AN ANATOMICAL STUDY

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.

A Variation of the Components’ Separation Technique that Preserves the Semilunaris for Treatment of Abdominal Wall Deformities

The variation of the components’ separation technique, which uses the anterior rectus sheath and the release of the oblique muscles, proved to be effective in tension reduction. This paper aimed to present the initial experience using a variation that preserves semilunaris through the incision of the lateral aspect of the rectus sheath. All of the 12 patients presented an abdominal wall defect that included incisional hernia, peritoneostomy, lateral implantation of the rectus muscle, and defect secondary to TRAM flap. The separation was done in the following stages: stage 1—anterior rectus sheath and stage 2—external oblique muscles. From the 12 patients, three presented early complications: seroma (n = 2) and epitheliolysis (n = 1). There were no recurrences or other late complications (48 months follow-up period). The separation of the anterior rectus sheath, and incision in the lateral recess to undermine the oblique muscles, allowed the treatment of abdominal wall defects, without late complications.

Evaluation of Double Mesh Modification of Chevrel’s Technique in Management of Midline Incisional Hernia

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.

The Relation Between the Distance of Rectus Plication and the Intra Abdominal Pressure Changes before and Immediately After Abdominoplasty

Background tummy tuck surgery, also known as abdominoplasty, removes excess fat and skin and, in most cases, restores weakened or separated muscles creating and abdominal profile that is smoother and firmer. Diastasis recti means the belly sticks out because the space between left and right belly muscles has widened. The most notable symptom of anterior abdominal wall weakness or diastasis recti is a noticeable protrusion in the stomach. This protrusion is caused by weakness and separation of the muscles in the mid-abdomen. Objective It was to evaluate the relationship between the distance of recto-fascial or recto-fascial diastasis placation and intra-abdominal pressure changes during and immediately after abdominoplasty. Patient and Methodology In this study we demonstrated if there was relation between rectus diastasis width and the increase of intra-abdominal pressure, to evaluate this correlation before and immediately after the plication of anterior rectus sheath in abdominoplasty. Seventy five meeting the inclusion criteria were selected. Results This study enrolled 75 healthy female patients, the study took place at Al-Jamila Hospital, performed in a period of 10 months, starting from March 2017 till December 2017.

Anterior abdominal wall endometrioma: a diagnostic dilemma

The presence of functioning endometrium outside the uterine cavity is often encountered in gynaecological practice but an extremely rare entity is its extra pelvic variant is seen sometimes around the umbilicus, anterior rectus sheath vesical region, also rarely seen around the kidney’s nasal mucosa, lungs and the pleura. The incidence of this condition is as low as 0.03% to 0.15%. Endometrioma of the anterior rectus sheath is well documented in literature but because of its rarity may pose a diagnostic dilemma. Reporting herewith a case of anterior rectus sheath endometrioma where medical line of treatment failed and surgical excision was required.
