PATIENT-CENTERED ANALGESIA OF THE ANTERIOR ABDOMINAL WALL IN CHILDREN OF DIFFERENT AGES: OWN EXPERIENCE

Introduction. Regional anesthesia in pediatric practice is one of the most valuable and safest tools for perioperative pain management. The advantages of regional anesthesia are early recovery of children, reducing opioid consumption, postoperative pain, respiratory complications, nausea, vomiting, as well as health care costs. The aim of the study was to analyze the data on the effect of the quadratus lumborum block and the transversalis fascia block on the duration and effectiveness of postoperative analgesia and propose a model of combining two blocks with a single injection. Materials and methods. Today there is growing interest in the use of new methods of regional anesthesia, especially the anterior and posterior torso blocks. The quadratus lumborum block and the transversalis fascia block are aimed at providing analgesia over the T7-L1 dermatomes, namely the ilio-inguinal and iliac nerves, which extend from the lateral portion of the psoas major, the lower edge of the 12th rib; however, there is evidence of cranial spread to the T4 – T5 dermatomes, and caudal spread to the L2 – L3 dermatomes. Currently, there are enough publications concerning the quadratus lumborum block and the transversalis fascia block. Results. For adequate perioperative multimodal anesthesia, the authors proposed a combination of the transversalis fascia block and the quadratus lumborum block with a single injection and ultrasound guidance. Conclusions. The advantages of the proposed method include simplicity, less invasiveness, adequate analgesia during surgery, as well as during the postoperative period (exclusion of somatic and visceral components), as evidenced by the assessment on a visual analogue scale (no more than two points). In addition, it significantly reduces the perioperative opioid use.

OV08 TREATMENT OF THE INGUINAL HERNIA USING THE SHOULDICE REPAIR

Aim The Shouldice procedure is a layered reconstruction of the posterior wall in inguinal hernia repair and currently the preferred method if the layers of the abdominal wall are of good quality, the wish of the patient for a non-mesh repair and if a mesh method is not possible or available. The correct performance of the reconstruction of the posterior wall is essential part of the operation. Material and Methods A life educational video was made with the four-layer reconstruction in detail. The first layer of the reconstruction starts at the medial corner and the conjoint tendon is sutured to the caudal flap of the transversalis fascia using a continuous non resorbable suture. The second layer of the reconstruction is made by approximating the cranial flap of the transversalis fascia and the posterior part of the inguinal ligament. The third layer starts at the level of the deep internal inguinal ring and approximates the lower border of the internal oblique muscle with the inguinal ligament. The fourth and final layer approximates the internal oblique muscle again with the inguinal ligament. Results The four-layer reconstruction after splitting the transversalis fascia is shown in detail since treatment of the hernia sac is like the other techniques. Conclusions The instructional video can be used for the resident training as a start in a hernia course followed by the execution on a model before the actual execution on a patient.

Functional anatomy of the abdominal wall

This chapter describes the functional anatomy of the abdominal wall. The layers of the abdominal wall consist of skin, superficial fascia, deep investing fascia, muscles, and inner fascial layers: transversalis fascia, extraperitoneal fascia, and peritoneum. The layers are variable in different areas of the abdomen. Skeletal support for the abdomen is derived from the lumbar vertebrae, the superior parts of the pelvic bones, and the bony parts of the inferior thoracic skeleton: the lower ribs and their costal cartilages and the xiphoid process.

Suture and Fixation of the Transversalis Fascia during Robotic-Assisted Transabdominal Preperitoneal Hernia Repair to Prevent Seroma Formation after Direct Inguinal Hernia Repair

Background. Seroma formation after videoendoscopic repair of inguinal hernias, known as “pseudorecurrence”, may vary from an asymptomatic, self-limiting occurrence to a painful, chronic problem. The aim of this study was to investigate the incidence of postoperative seroma in robotic-assisted transabdominal preperitoneal hernia repair (R-TAPP), modified by suturing and fixating the transversalis fascia to the Cooper ligament. Methods. The study was approved by the local ethics committee (2019-01132 CE-3495). Patients undergoing R-TAPP for direct inguinal hernia from October 2017 to December 2019 were included. In all patients, a barbed running suture of the transversalis fascia was performed to close the cavity resulting from the direct hernia reduction and to fix it to the Cooper ligament, then a lightweight mesh was placed. Demographic and clinical data were collected and analysed. Results. Over the study period, 67 R-TAPP in 51 patients were identified. All patients were male, with a mean age of 63.1 ± 12.7 years. There was 1 case of conversion to open surgery due to adhesions of the caecum to the groin as a result of perforated appendicitis. The mean length of the hospital stay was 1.8 ± .6 days. After discharge, no cases of seroma or recurrence at 30 days nor chronic pain at a mean follow-up of 10.3 ± 6.8 months was detected. Conclusions. In the treatment of direct inguinal hernia with R-TAPP, suturing and anchoring the transversalis fascia to the Cooper ligament are safe, feasible and recommendable in order to prevent postoperative seromas.
