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.

Background Blockade of parietal nociceptive afferents by the use of continuous wound infiltration with local anesthetics may be beneficial in a multimodal approach to postoperative pain management after major surgery. The role of continuous preperitoneal infusion of ropivacaine for pain relief and postoperative recovery after open colorectal resections was evaluated in a randomized, double-blinded, placebo-controlled trial. Methods After obtaining written informed consents, a multiholed wound catheter was placed by the surgeon in the preperitoneal space at the end of surgery in patients scheduled to undergo elective open colorectal resection by midline incision. They were thereafter randomly assigned to receive through the catheter either 0.2% ropivacaine (10-ml bolus followed by an infusion of 10 ml/h during 48 h) or the same protocol with 0.9% NaCl. In addition, all patients received patient-controlled intravenous morphine analgesia. Results Twenty-one patients were evaluated in each group. Compared with preperitoneal saline, ropivacaine infusion reduced morphine consumption during the first 72 h and improved pain relief at rest during 12 h and while coughing during 48 h. Sleep quality was also better during the first two postoperative nights. Time to recovery of bowel function (74 +/- 19 vs. 105 +/- 54 h; P = 0.02) and duration of hospital stay (115 +/- 25 vs. 147 +/- 53 h; P = 0.02) were significantly reduced in the ropivacaine group. Ropivacaine plasma concentrations remained below the level of toxicity. No side effects were observed. Conclusions Continuous preperitoneal administration of 0.2% ropivacaine at 10 ml/h during 48 h after open colorectal resection reduced morphine consumption, improved pain relief, and accelerated postoperative recovery.

PURPOSE: Compare, in a rabbit model, the inflammatory response and adhesions formation following surgical fixation of polypropilene and Vypro mesh in the inguinal preperitoneal space. METHODS: Fourteen male New Zealand rabbits, weighing between 2.000 to 2.500 g were used. A midline incision was made and the peritoneal cavity was exposed. The 2,0X1,0 cm polypropylene mesh was fixed in the left flank and secured to the margins with 3-0 prolene in a separate pattern. In the right flank, a 2,0X1,0 cm Vypro II mesh was sewn in the same way. After the post surgical period, the animals were again anesthetized and underwent laparoscopic approach, in order to identify and evaluate adhesions degree. Both fixed prosthesis were excised bilaterally with the abdominal wall segment, including peritoneum, aponeurosis and muscle and sent to a pathologist RESULTS: Operative time ranged from 15 to 25 minutes and no difficulties in applying the mesh were found. From the 14 polypropylene meshes fixed to the intact peritoneum, 11 had adhesions to the abdominal cavity (78,6%). Concerning Vypro mesh, 12 animals developed adhesions from the 14 with mesh fixation (85,7%). Histological examination of tissues harvested revealed fibroblasts, collagen, macrophages and lymphocytes between the threads of the mesh. CONCLUSION: Polypropylene and Vypro mesh, when implanted in the peritoneal cavity of rabbits provoke similar amount of adhesions. Vypro mesh tissues had higher fibrosis resulting in better mesh incorporation to the abdominal wall.

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 to explain and show the feasibility of laparoscopic TAPP technique in emergency procedures Material and Methods we present a 71-year-old female with personal history of obesity (BMI 32) and a laparoscopic right hemicolectomy performed in 2018, presenting at the ER with a 24-hour intestinal obstruction due to incarcerated ventral incisional hernia. Results laparoscopic reduction of the hernia contents was achieved without need of intestinal resection, prior to access to the preperitoneal space, creating a peritoneal flap that was dissected around the hernia. Following closure of the hernia defect, a polypropylene mesh was placed and the peritoneal flap closed. There were no intraoperative or postoperative events and patient was discharged on 3rd POD. Conclusions laparoscopic approach to emergency hernias in selected patients doesn’t differ from elective surgery, and offers great advantages in terms of evaluation of the incarcerated elements, and postoperative recovery, especially in obese patients where a conventional open approach has higher morbidity.

Prevesical Space

The extraperitoneal space extends between peritoneum and investing fascia of muscles of anterior, lateral and posterior abdominal and pelvic walls, and circumferentially surrounds the abdominal cavity. The retroperitoneum, which is confined to the posterior and lateral abdominal and pelvic wall, may be divided into three surgicoanatomic zones: centromedial, lateral (right and left), and pelvic. The preperitoneal space is confined to the anterior abdominal wall and the subperitoneal extraperitoneal space to the pelvis. In the extraperitoneal tissue, condensation fascias delineate peri- and parasplanchnic spaces. The former are between organs and condensation fasciae, the latter between this fascia and investing fascia of neighboring muscles of the wall. Thus, perirenal space is encircled by renal fascia, and pararenal is exterior to renal fascia. Similarly for the urinary bladder, paravesical space is between the umbilical prevesical fascia and fascia of the pelvic wall muscles—the prevesical space is its anterior part, between transversalis and umbilical prevesical fascia. For the rectum, the “mesorectum” describes the extraperitoneal tissue bound by the mesorectal condensation fascia, and the pararectal space is between the latter and the muscles of the pelvic wall. Perisplanchnic spaces are closed, except for neurovascular pedicles. Prevesical and pararectal (presacral) and posterior pararenal spaces are in the same anatomical level and communicate. Anterior to the anterior layer of the renal fascia, the anterior interfascial plane (superimposed and fused mesenteries of pancreas, duodenum, and colon) permits communication across the midline. Thus parasplanchnic extraperitoneal spaces of abdomen and pelvis communicate with each other and across the midline.

The purpose of the study is experimental development of preperitoneal inguinal hernioplasty with synthetic mesh, according assessment of the need of its fixation to the tissues. Materials and methods. An inguinal hernia was simulated on human cadaveric material. The study used 27 male corpses. Two inguinal hernias were modeled on one corpse: on one side - indirect, on the other - direct. A polypropylene mesh (standard density, 15 x 15 cm) was placed in the preperitoneal space. The endoprosthesis was impacted from the side of the abdominal cavity by a special designed device. The effect of a peak intra-abdominal pressure of 200 mm Hg was simulated. The degree of displacement of the reticular endoprosthesis into the inguinal canal was estimated at the moment of peak pressure on it from inside the abdominal cavity. For a simulated indirect inguinal hernia, two variants of the technique were considered: with fixation of the endoprosthesis to the underlying tissues and without fixation. For the modulated direct inguinal hernia, the following options were considered: non-fixative, with fixation at one point to the pubis and with plasty of the transverse fascia. Results. When modeling preperitoneal plasty of a direct inguinal hernia, there is a pronounced displacement of the endoprosthesis into the inguinal canal with a non-fixing plasty, unlike the method with transverse fascia plasty or fixation to the pubis. In indirect inguinal hernia, there was no significant displacement of the endoprosthesis in both considered variants. Conclusions. According to the obtained results, conclusions were drawn on the need for additional plasty of the transverse fascia or fixation of the endoprosthesis at a single point in a direct inguinal hernia. With indirect inguinal hernia in the experiment, no significant difference in the displacement of the mesh endoprosthesis into the inguinal canal was obtained with and without fixation.
