[Robotic hernia surgery : Part I: Robotic inguinal hernia repair (r­TAPP).

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.

Pneumatic positioning and mesh fixation in laparoscopic ventral/incisional hernia repair. New surgical technique and a new device.

AIM: To achieve full-surface contact of a prosthetic mesh with the abdominal wall (avoiding folds and wrinkles) in laparoscopic ventral/ incisional hernia repair (LVHR/ LIHR) and to fix the mesh with glue using a new surgical technique and a new device, developed for this specific procedure. MATERIAL OF STUDY: New surgical technique associated with a new surgical pneumatic device allows perfect positioning and extension of the intraperitoneal mesh and facilitates the glue application and mesh fixation. A polyester composite mesh is used for intraperitoneal placement, cyanoacrylate glue is used for mesh fixation. Pigs cadavers were used to test this new technique and the device*. RESULTS: With the help of a pneumatic device the intraperitoneal mesh can be well positioned and perfectly extended without folds, thus allowing an efficient and strong mesh glue fixation. CONCLUSION: Presented pneumatic positioning device is useful to achieve an ideal alignment of mesh with the abdominal wall and supports the fixation task. The proposed technique enables the glue application safely, by avoiding possible spillage over intestinal loops and offering the necessary time for the distribution of such fast polymerizing glue. This technique could also be applied with other types of glue or self-adhesive mesh.

Causes of recurrence in laparoscopic inguinal hernia repair.

AIM: The analysis of possible mechanisms of repair failure is a necessary instrument and the best way to decrease the recurrence rate and improve the overall results. Avoiding historical errors and learning from the reported pitfalls and mistakes helps to standardize the relatively new laparoscopic techniques of trans-abdominal preperitoneal and total extraperitoneal. MATERIALS AND METHODS: The video tapes of all primary laparoscopic repairs done by the author that led to recurrence were retrospectively analyzed and compared with findings at the second laparoscopic repair. A review of the available cases of recurrences occurring between 1994 and 2003 is the basis of this report. SUMMARY: Adequate mesh size, porosity of mesh material, slitting of the mesh, correct and generous dissection of preperitoneal space and wrinkle-free placement of the mesh seem to be the more important factors in avoiding recurrence rather than strength of the material or strong penetrating fixation. Special attention should be paid to preperitoneal lipoma as a possible overlooked herniation or potential future pseudorecurrence despite nondislocated correctly positioned mesh. CONCLUSION: Laparoscopic hernia repair is a complex but very efficient method in experienced hands. To achieve the best possible results, it requires an acceptance of a longer learning curve, structured well-mentored training and high level of standardization of the operative procedure.
