Laparoscopic TAPP to treat inguinal hernia. Is the robot preferable? A review and cohort-study on anatomical landmarks of robotic-assisted transabdominal preperitoneal groin hernia repair (r-TAPP).

In this review, the advantages of the robotic platform in rTAPP are presented and discussed. Against the background of the unchanged results of conventional TAPP for decades (approx. 10% chronic pain and approx. 3.5% recurrence), a new anatomy-guided concept for endoscopic inguinal hernia repair with the robot is presented. The focus is on the identification of Hesselbach's ligament. The current results give hope that the results of TAPP can be improved by rTAPP and that rTAPP is not just a more expensive version of conventional TAPP. To support the rationale presented here, we analyzed 132 video recordings of rTAPP's for the anatomical structures depicted therein. The main finding is, that in all cases (132/132 or 100%) Hesselbach's ligament was present and following its lateral continuity with the ileopubic tract offered a safe framework to develop all the critical anatomical structures for clearing the myopectineal orifice, repair the posterior wall of the groin and perform a flawless mesh fixation. Future studies are needed to integrate all the resources of the robotic platform into an rTAPP concept that will lead out of the stalemate of the indisputably high rate of chronic pain and recurrences.

Robotic hernia surgery IV. English version : Robotic parastomal hernia repair. Video report and preliminary results.

The surgical treatment of parastomal hernias is considered complex and is known to be prone to complications. Traditionally, this condition was treated using relocation techniques or local suture repairs. Since then, several mesh-based techniques have been proposed and are nowadays used in minimally invasive surgery. Since the introduction of robot-assisted surgery to the field of abdominal wall surgery, several adaptations to these techniques have been made, which may significantly improve patient outcomes. In this contribution, we provide an overview of available techniques in robot-assisted parastomal hernia repair. Technical considerations and preliminary results of robot-assisted modified Sugarbaker repair, robot-assisted Pauli technique, and minimally invasive use of a funnel-shaped mesh in the treatment of parastomal hernias are presented. Furthermore, challenges in robot-assisted ileal conduit parastomal hernia repair are discussed. These techniques are illustrated by photographic and video material. Besides providing a comprehensive overview of robot-assisted parastomal hernia repair, this article focuses on the specific advantages of robot-assisted techniques in the treatment of this condition.

Excess Body Weight and Abdominal Hernia.

BACKGROUND: Obese patients have an increased incidence of ventral hernias; in over 50% of these cases, patients are symptomatic. At the same time, morbid obesity is a disease of epidemic proportions. The combination of symptomatic hernia and obesity is a challenge for the treating surgeon, because the risk of perioperative complications and recurrence increases with increasing BMI. SUMMARY: This review outlines this problem and discusses interdisciplinary approaches to the management of affected patients. In emergency cases, the hernia is treated according to the surgeon's expertise. In elective cases, an individual decision must be made whether bariatric surgery is indicated before hernia repair or whether both should be performed simultaneously. After bariatric surgery a weight reduction of 25-30% of total body weight in the first year can be achieved and it is often advantageous to perform a bariatric operation prior to hernia repair. Technically, the risk of complications is lower with minimally invasive procedures than with open ones, but laparoscopy is challenging in obese patients, and meshes can only be implanted in intraperitoneal position. This mesh position has to be questioned because of adhesions, recurrence rate, and risk of contamination during re-interventions in patients who are often still relatively young. KEY MESSAGES: Obese patients with hernia need to be approached in an interdisciplinary manner, in some patients a weight loss procedure may be advantageous before hernia repair. Recent data show the benefits of robotic hernia surgery in obese patients, as not only haptic advantages result, but especially the mesh can be implanted in a variety of extraperitoneal positions in the abdominal wall with low morbidity.

Robotic hernia repair III. English version : Robotic incisional hernia repair with transversus abdominis release (r­TAR). Video report and results of a cohort study.

The principle of targeted separation or weakening of individual components of the abdominal wall to relieve tension in the median line during major abdominal reconstruction has been known for over 30 years as anterior component separation (aCS) and is an established procedure. In search of alternatives with lower complication rates, posterior component separation (pCS) was developed; transversus abdominis release (TAR) is a nerve-sparing modification of pCS. With the ergonomic resources of robotics (e.g., angled instruments), TAR can be performed in a minimally invasive manner (r-TAR): hernia gaps of up to 14 cm can be closed and a large extraperitoneal mesh implanted. In this video article, the treatment of large incisional hernias using the r­TAR technique is presented. Exemplary results of a cohort study in 13 consecutive patients are presented. The procedure is challenging, but our own results-as well as reports from the literature-are encouraging. The r­TAR is becoming the pinnacle procedure for abdominal wall reconstruction.

Robotic hernia repair II. English version : Robotic primary ventral and incisional hernia repair (rv­TAPP and r­Rives or r­TARUP). Video report and results of a series of 118 patients.

Endoscopic management of umbilical and incisional hernias has adapted to the limitations of conventional laparoscopic instruments over the past 30 years. This includes the development of meshes for intraperitoneal placement (intraperitoneal onlay mesh, IPOM), with antiadhesive coatings; however, adhesions do occur in a significant proportion of these patients. Minimally invasive procedures result in fewer perioperative complications, but with a slightly higher recurrence rate. With the ergonomic resources of robotics, which offers angled instruments, it is now possible to implant meshes in a minimally invasively manner in different abdominal wall layers while achieving morphologic and functional reconstruction of the abdominal wall. This video article presents the treatment of ventral and incisional hernias with mesh implantation into the preperitoneal space (robot-assisted transabdominal preperitoneal ventral hernia repair, r­ventral TAPP) as well as into the retrorectus space (r-Rives and robotic transabdominal retromuscular umbilical prosthetic repair, r­TARUP, respectively). The results of a cohort study of 118 consecutive patients are presented and discussed with regard to the added value of the robotic technique in extraperitoneal mesh implantation and in the training of residents.

Videobeitrag und Ergebnisse einer Kohortenstudie an 302 operierten Hernien.

The treatment of inguinal hernias with open and minimally invasive procedures has reached a high standard in terms of outcome over the past 30 years. However, there is still need for further improvement, mainly in terms of reduction of postoperative seroma, chronic pain, and recurrence. This video article presents the endoscopic anatomy of the groin with regard to robotic transabdominal preperitoneal patch plasty (r­TAPP) and illustrates the surgical steps of r­TAPP with respective video sequences. The results of a cohort study of 302 consecutive hernias operated by r­TAPP are presented and discussed in light of the added value of the robotic technique, including advantages for surgical training. r­TAPP is the natural evolution of conventional TAPP and has the potential to become a new standard as equipment availability increases and material costs decrease. Future studies will also have to refine the multifaceted added value of r­TAPP with new parameters.

[Laparostoma-Avoidance and treatment of complications]. / Laparostoma ­ Vermeidung und Therapie von Komplikationen.

The open abdomen (OA) is an established concept for treating severe abdominal diseases. The most frequent reasons for placement of an open abdomen are abdominal sepsis (e.g. from intestinal perforation or anastomotic leakage), severe abdominal organ injury and abdominal compartment syndrome. The pathophysiology is much more complex than the surgeon's eye can see in an OA. The temporary closure of the abdominal wall ensures sufficient drainage of infected ascites, protection of the intestinal loops and conditioning of the abdominal wall in order to be able carry out definitive closure of the abdominal wall at the end of the surgical treatment. Negative peritoneal pressure therapy combined with fascia traction (with or without mesh) is well-established in the management of an open abdomen.
