Laparoscopic incisional hernia repair is primarily performed using the IPOM method5, for which the placement and fixation of the mesh are key to achieving good outcomes. If the placement and fixation of the mesh are improper, the mesh will not adhere tightly to the abdominal wall and may be wrinkled or displaced. Improper mesh fixation is associated with seroma formation, abdominal infection, chronic pain, and hernia recurrence. Specifically, the treatment for mesh infections involves puncture and...

Incisional hernia is a common complication after abdominal surgery and can be properly treated only with surgery1. Compared with traditional open incision herniorrhaphy, laparoscopic herniorrhaphy has the advantages of less surgical trauma, a lower infection rate, and faster postoperative recovery2,3. Currently, laparoscopic herniorrhaphy is the method of choice for the treatment of incisional hernia if there are no contraindications4.
However, laparoscopic herniorrhaphy is technically complex. Intraperitoneal onlay mesh (IPOM) is commonly used in laparoscopic incisional hernia repair, and this involves placing a mesh into the abdominal cavity laparoscopically to cover the hernia defect5. The mesh is a new type of medium-weight monofilament polypropylene mesh covered with a hydrogel barrier on the visceral side6. For laparoscopic incisional hernia repair using the IPOM method, it is necessary to master the placement of the trocars, the techniques to separate intra-abdominal adhesions, the techniques for suturing the incisional hernia, and the methods for placing and fixing the mesh in the abdominal cavity. In particular, if the mesh is not properly placed and fixed, this can result in the recurrence of the hernia, as well as potentially serious complications such as intestinal obstruction and mesh infection7,8. Therefore, mastering the correct mesh fixation technique is an important criterion for achieving a good surgical outcome. 
The traditional method of mesh fixation for incisional hernia is to fix the mesh with a double-ring hernia nail. After the mesh is placed into the abdominal cavity, the edge of the mesh is fixed with a nail gun first, and then the edge of the hernia ring is fixed9. However, this method has poor spatial positioning, and the mesh is prone to displacement, leading to hernia recurrence. By reviewing and analyzing the various mesh fixation methods, a new "contraposition and alignment" method for mesh fixation is proposed and presented in this protocol10. In this method, the size and scope of the incisional hernia are measured in advance, after which the mesh fixation points can be marked in advance. When the mesh is placed into the abdominal cavity during the operation, nail gun fixation and suture fixation can be performed according to the previously marked locations. This method can reduce the difficulty of the operation, the operation time, the medical cost, and the occurrence of complications. In this study, this new method is compared with the conventionally used double-loop hernia nail fixation method for mesh fixation during laparoscopic incisional hernia repair surgery.

application of a new mesh fixation method in laparoscopic incisional hernia repair

Laparoscopic incisional hernia repair using intraperitoneal onlay mesh (IPOM) is one of the most widely used minimally invasive methods for repairing incisional hernias. The laparoscopic IPOM involves implanting the mesh into the abdominal cavity through laparoscopy to repair an abdominal wall hernia. In the IPOM surgery, after the closure of the hernia ring, an anti-adhesion mesh is placed laparoscopically. The correct placement of this mesh is critical to the success of the method, and surgical skills are required to achieve perfect placement. If the mesh placement is not mastered properly, the operation and anesthesia time will be prolonged. In addition, improper placement of the mesh can lead to serious consequences, such as intestinal obstruction and mesh infection. A "contraposition and alignment" mesh fixation method is described in this study, which involves pre-marking the fixation position of the mesh to reduce the difficulty of mesh placement. A properly placed mesh is completely flat on the peritoneum, the edges are not curled or wrapped, and the mesh is adhered firmly such that there is no displacement after removing the pneumoperitoneum pressure. The "contraposition and alignment" mesh fixation technique offers the advantages of reliable placement of the mesh and fewer complications than other techniques, and it is easy to learn and master. It also allows for positioning the nail gun in advance based on the anatomy of the incisional hernia. This enables the use of the minimum number of nails possible while still ensuring good fixation, which can reduce the occurrence of complications and reduce the cost of surgery. Thus, the mesh fixation method described here is highly suitable for clinical applications based on the aforementioned advantages.

Either &#34;contraposition and alignment&#34; mesh fixation (experimental group) or traditional double-loop hernia nail fixation (control group) was performed for the patients in the study, with 42 patients in each group.
During the hernia repair surgery performed in this study, the anti-adhesion mesh was placed after the hernia ring was sutured. In the experimental group, the &#34;contraposition and alignment&#34; method was used to place the mesh, while the traditional double-loop fixation m...

Application of a New Mesh Fixation Method in Laparoscopic Incisional Hernia Repair

Presented here is a method for improving the mesh placement in laparoscopic incisional hernia repair, which can shorten the time required for mesh fixation and reduce the occurrence of postoperative chronic pain.

Laparoscopic incisional hernia repair using intraperitoneal onlay mesh (IPOM) is one of the most widely used minimally invasive methods for repairing ...

This protocol provides a new method to effectively solve the problem of mesh fixation in laparoscopic incisional hernia repair. The advantages of this method include accurate mesh positioning, firm fixation, and easy learning, especially for beginners. After mastering this method, the time of mesh fixation during operation can be significantly reduced.Text and picture demonstration cannot effectively show the whole process of this mesh fixing method, hence, visual demonstration enables understanding all of the details of this method. Begin by selecting an appropriate size anti-adhesion mesh, measure and mark the approximate range of the incisional hernia on the abdominal wall surface with a sterile ruler and marking pen. The size of the hernia ring defect can also be measured by a pre-operative CT examination.Place the ruler parallel to the longitudinal axis of the hernia defect and measure the maximum longitudinal length of the defect. Select an appropriately sized anti-adhesion mesh according to the size of the hernia ring defect. Ensure that the coverage of the mesh exceeds the edge of the defect by at least five centimeters.Mark the longitudinal length of the defect on the mesh and mark the nail gun fixation points at intervals of five centimeters on the longitudinal axis. Then extend the fixation points more than five centimeters along the marked line to the edge of the mesh which pertains to the alignment. Mark the nail gun fixation points evenly every two to three centimeters along the edge of the mesh which pertains to the contraposition.Ensure that the fixing points of the nail gun are uniformly marked two centimeters from the longitudinal axis of the defect on both sides with an interval of three centimeters. Roll the mesh such that the anti-adhesion surface will face the abdominal wall and place the rolled mesh into the abdominal cavity through the 12-millimeter puncture hole. Then unfold the mesh under laparoscopic guidance.Ensure that the marked line of the unrolled mesh overlaps the longitudinal axis of the hernia ring defect. Fix the marked points on the longitudinal axis of the mesh to the abdominal wall with non-absorbable nails using a nail gun. Fix the edge of the mesh to the abdominal wall along the marked points on the edge of the mesh with non-absorbable nails using a nail gun.Fix the mesh on the abdominal wall along the marked points on both sides of the longitudinal axis of the mesh with absorbable nails using a nail gun. The contraposition and alignment mesh fixation or traditional double-loop hernia nail fixation was performed in the experimental and control groups respectively with 42 patients in each group. The mean mesh placement time for the experimental group was approximately 32.5 minutes which was notably lower than the control group, having a mesh placement time of about 44.7 minutes.There were only two cases of chronic pain in the experimental group, significantly lower than the eight cases observed in the control group. However, there were no significant differences between the two groups in terms of seroma formation, mesh infection, recurrence of incisional hernia, the length of the post-operative hospital stay, and hospitalization expenses. Ensure that the mesh placement is accurate with adequate coverage and that precise fixation methods have been used.The application of the contraposition and alignment mesh fixation method is not limited to incisional hernia repair, but can also be used for laparoscopic parastomal hernia mesh repair and laparoscopic esophageal hiatal hernia mesh repair.
