Abstract Aim The Madrid APPROACH is the combination of an absorbable mesh and a permanent retromuscular mesh for the treatment of the complex abdominal wall problems. It has been controversial because of the need of two different meshes. We present a clinic case to show the utility of this technique and how it allows rebuilding the inguinal ligament. Material and Methods 78 years old woman who underwent a right ilioinguinal and obturatriz lymphadenectomy due to a melanoma. Incisional hernia fixed in 2018 with a retromuscular polyester mesh. New incisional iliac hernia (L3) over the right iliac vessels, with an absence of inguinal ligament, right rectus atrophy, and the previous mesh being part of the sac. Surgery: incision over the previous scar. Wide dissection of the preperitoneal space, Retzius space and lateral to the cuadratus lumborum, retrodiafragmatic dissection, lateral transverse abdominus release, and cross-over to the retrorectal left space. Preperitoneal BioA mesh and an upper 40x40cm medium weight polipropilene mesh set to both Cooper ligaments. Results After two and a half months, a PET-TC showed the BioA mesh perfectly adapted to the abdominal wall and rebuilt a new inguinal ligament. Also intense FDG capitation of the mesh due to the high cellular metabolism. Two years later the patient has a continent abdominal wall, the follow up TC shows the disappearance of the absorbable mesh and the perfect abdominal wall rebuilt. Conclusions The BioA mesh acts like a tissue scaffold for new conjunctive tissue as we see the intense FDG captation. The Madrid APPROACH allows giving response to very complex abdominal wall problems.

Abstract Background A congenital prepubic sinus (CPS) is a rare congenital anomaly in which a duct remnant extends from the skin opening near the pubic symphysis to various parts and the lesions are mostly located in the preperitoneal space. The totally extraperitoneal (TEP) approach is an operational method that provides a good field of view for the preperitoneal space. We report the CPS through the pubic symphysis in which complete resection was achieved by a TEP approach. TEP approach was minimally invasive and achieved satisfactory cosmetic outcome. Case presentation We herein report the case of a 13-year-old boy with a fistula opening near the dorsal penis. He was admitted to our hospital due to fever and lower abdominal pain. Abdominal ultrasonography and computed tomography revealed an abscess inside a fistula lumen on the posterior surface of the rectus abdominis muscles in the midline of the lower abdomen. Under a diagnosis of CPS, which was located in the preperitoneal space, endoscopic resection was performed by a totally extraperitoneal approach. After making an umbilical incision, the rectus abdominis muscle was excised outward to expose the preperitoneal space. A single-port system was placed in the preperitoneal space. Three 5-mm-port trocars were inserted. As the preperitoneal cavity was expanded, a sinus connecting to the pubic symphysis was confirmed. The pubic symphysis did not connect with the bladder. Because the fistula was penetrated with the pubic symphysis, the remaining caudal fistula was removed from the body surface with a small spindle-shaped incision around the fistula opening. Finally, the sinus was completely resected, with confirmation from both the cranial side and dorsal side of the pubic symphysis. We were able to perform complete resection of the CPS with good visibility and without any peritoneal damage. There were no intraoperative complications. His postoperative course was uneventful during the 1-year follow-up. Conclusions The TEP approach may be feasible for the resection of a CPS and may allow safe and secure resection due to good visibility, even in pediatric patients.

AIM: to determine the prospects for the preventive endoprosthetics of the abdominal wall at preventing the development of postoperative ventral hernias. MATERIALS AND METHODS: A meta-analysis of the literature data performed to determine the effectiveness of preventive endoprosthetics for the prevention of ventral hernia formation. Topographical study has been conducted to explore the most promising levels of the mesh location. RESULTS: During the meta-analysis it has been found that performing preventive endoprosthesis of the anterior abdominal wall t in the preperitoneal space reduces the frequency of ventral hernias. There were no significant differences in the frequency of infectious complications and serom in the experimental and control groups according to studied publications. During the preparation it has been distinguished that between the transverse fascia and the peritoneum there is a preperitoneal fascia consisting of two leaves, which is most manifest in the lateral parts. In the umbilical region above linea arcuata the preperitoneal fascia is thinned and represented by separate fibers that are difficult to differentiate as a structure between the transverse fascia and the peritoneum. In the lateral parts of the abdominal wall, the preperitoneal fascia is well expressed. It has been distinguished that the retroperitoneal fascia, formed by the junction of two sheets of the Gerot fascia continues into the fascia between the transverse fascia and the peritoneum. CONCLUSION: Preventive endoprosthesis of the anterior abdominal wall is an effective and safe method of preventing the formation of postoperative ventral hernias. The anterior abdominal wall is characterized by a complex multifascial structure, which is of fundamental importance for various types of surgery. Between the transverse fascia and the peritoneum there is preperitoneal fascia which is represented by two leaflets. Its continuation is the retroperitoneal fascia (5 figures, 2 tables, bibliography: 8 refs).

Purpose. To perform totally extraperitoneal repair of a hernia, it is essential to create a working space for the placement of instruments. In this study, we aimed to compare balloon dissection (BD) and camera or telescopic dissection (CD) with respect to the surgical outcomes, without considering the cost-effectiveness. Methods. Forty consecutive, healthy, unilateral inguinal hernia patients who underwent Totally Extraperitoneal Repair hernia repair were randomized into 2 groups according to whether they received BD or CD. The perioperative demographic characteristics were recorded. All the operations were video recorded from the beginning to the end of each procedure. The virtually constructed periods of the procedures were evaluated by another surgeon who watched each video. The time spent for each period, the severity score assigned by the surgeon, the total operation time, the peritoneal laceration rate, the presence of early and late postoperative pain, the number of postoperative visits, the total analgesic requirements, and the complications were recorded. Results. The demographic properties of the patients, the perioperative and postoperative complications, and the severity scores in the BD and CD groups were statistically similar. The total operating time and the time from the dissection of the peritoneum to the reduction of the hernia sac were significantly longer in the CD group. Post-discharge analgesic consumption, Visual Analog Scale scores, and the number of visits were similar between the groups. Conclusions. The dissection of the working space in the preperitoneal area can be achieved using camera dissection without the risk of common complications associated with balloon dissection, particularly balloon rupture.

Background: Laparoscopic repair of inguinal hernia is steadily gaining popularity among general surgeons. Laparoscopically the preperitoneal space can be approached in two different ways, as a result of which two techniques of laparoscopic repair have emerged. We performed this study to compare the two techniques in a randomized setting in order to ascertain, if possible, which of these techniques is preferable when there is a choice.  Methods: This randomized, comparative study was conducted at Shri Mahant Indiresh hospital, Dehradun over a period of three years. Patients with unilateral, uncomplicated, inguinal hernia were randomized into two groups for undergoing surgery using either of these techniques. Patients’ demography and both intraoperative and postoperative variables were compared between the two groups.Results: Mean duration of surgery and mean pain scores in early postoperative period were found to be higher for transabdominal preperitoneal (TAPP) group as compared to totally extraperitoneal (TEP) group. Intraoperative and postoperative complications as well as hospital stay were not significantly different between the two groups.Conclusions: In this study TEP has been found to have an edge over TAPP in some respect but as per the available evidence both techniques are safe and choice of procedure may be tailored according to individual cases.

Aim. To evaluate diagnostic value of laparoscopic inguinal allohernioplasty in identification of occult forms of hernias of the inguinal region. Materials and Methods. The study was conducted on the basis of the results of surgical treatment of patients with inguinal hernias on the base of the Department of Hospital Surgery of RyazSMU in Ryazan State Emergency Care Hospital and on the base of the Department of Surgery, Obstetrics and Gynecology of Additional Postgraduate Education Faculty in Ryazan Regional Clinical Hospital, from 2015 to 2020 (n=207). Operations were performed with the absence of contraindications to narcosis and carboxyperitoneum, and if patients desired to be operated on by the proposed method. In all the patients included into the study, hernioplasty was performed using laparoscopic approach, with preperitoneal placement of the endoprosthetic mesh. For purity of the experiment, only polypropylene meshes were used. Standard meshes from monofilament polypropylene were used with surface density 65-80 g/m2 and volumetric porosity 80-85%. Meshes 15x15 cm dimension were used with cut angle with 7.5A cm catheti. Results. Of 207 patients, 28 were operated on for bilateral inguinal hernias. Only in one of them hernia was diagnosed in the preoperative stage. In the rest 27 patients, an occult hernia was found opposite to the previously diagnosed side. In 17 patients, besides hernias diagnosed in the preoperative and intraoperative stages, occult hernias were detected in the process of dissection of the preperitoneal space. Conclusion. Laparoscopic inguinal allohernioplasty permits to diagnose occult hernias that were not detected in the preoperative examination: femoral, obturator, inguinal hernias on the contralateral and/or unilateral side. This permits to perform hernioplasty taking into account the intraoperative finding, in one surgical procedure without subjecting the patient to repeated hospitalization, narcosis and operation.
