The clinical applications of D-type parastomal hernia repair surgery.

OBJECTIVE: This study investigated the use of a modified laparoscopic repair of paraostomy hernia technique, called "D-Type parastomal hernia repair surgery" which combines abdominal wall and extraperitoneal stoma reconstruction, in patients with parastomal hernia (PSH) following colorectal stoma surgery. The aim was to determine whether D-type parastomal hernia repair surgery is a promising surgical approach compared to the traditional laparoscopic repair technique (Sugarbaker method) for patients with PSH. METHODS: PSH patients were selected and retrospectively divided into two groups: the study group underwent D-type parastomal hernia repair, while the control group underwent laparoscopic Sugarbaker repair. Clinical data from both groups were analyzed. RESULT: Compared to control group (n = 68), the study group undergoing D-type stoma lateral hernia repair had significant increase in total operative time (98.82 ± 12.37 min vs 124.61 ± 34.99 min, p < 0.001). The study group also showed better postoperative stoma bowel function scores in sensory ability, frequency of bowel movements, and clothing cleanliness without a stoma bag (p = 0.037, 0.001, 0.002). The treatment cost was significantly higher in the control group (3899.97 ± 260.00$ vs 3215.91 ± 230.03$, p < 0.001). The postoperative recurrence rate in the control group was 26.4%, while in the study group, it was 4.3%, with a significant statistical difference (p = 0.024). In terms of long-term postoperative complications, the study group had an overall lower incidence compared to the control group (p = 0.035). Other parameters showed no significant differences between the two groups. CONCLUSION: The study suggests that D-type parastomal hernia repair surgery is a safe and feasible procedure. Compared to traditional surgery, it can reduce the recurrence of lateral hernia, improve postoperative stoma bowel function, and save medical resources.

Robotic versus open lateral abdominal hernia repair: a multicenter propensity score matched analysis of perioperative and 1-year outcomes.

PURPOSE: Lateral abdominal hernias are inherently challenging surgical entities. As such, there has been an increase in the adoption of robotic platforms to approach these challenging hernias. Our study aims to assess and compare outcomes between open (oLAHR) and robotic (rLAHR) lateral abdominal hernia repair using a national hernia-specific database. METHODS: A retrospective review of prospectively collected data from the Abdominal Core Health Quality Collaborative was performed to include all adult patients who underwent elective lateral hernia repair. A propensity score match analysis was conducted, and univariate analyses were conducted to compare these two surgical modalities across perioperative timeframes. RESULTS: The database identified 2569 patients. Our analysis matched 665 patients to either the open or robotic groups. The median length of stay, surgical site occurrences (SSO), and surgical site occurrences requiring procedural interventions (SSOPI) were higher in the oLAHR versus the rLAHR group. Overall, oLAHR had a significantly higher rate of having any post-operative complications or any SSO/SSOPI. There was no difference in quality-of-life measures between groups at 30 days and 1 year. CONCLUSION: Robotic abdominal hernia repair is a safe alternative compared to the open repair of lateral abdominal hernias with better perioperative outcomes. Despite having a longer operative time, the robotic approach can offer a significantly shorter length of stay and an overall lower rate of complications. Ultimately, there is no difference in the quality-of-life measures both at 30 days and 1 year between the open and robotic approaches.

Lateral hernia secondary to colorectal submucosal resection repaired by robotic-assisted approach: Case report.

INTRODUCTION AND IMPORTANCE: Lateral abdominal wall defects are a rare event and commonly result from iatrogenic causes and trauma. We report the first known case of flank hernia after endoscopic submucosal resection of a colonic polyp complicated by colonic perforation. CASE PRESENTATION: This is a case of a 50-year-old male who underwent endoscopic colonic resection complicated by perforation of the colon. Eight months later, he presented with an enlarging, asymptomatic left flank bulge. CT showed a large flank hernia which was successfully repaired using a robotic transabdominal preperitoneal (TAP) approach. CLINICAL DISCUSSION: The hypothesis is that the endoscopic resection with colonic perforation caused an iatrogenic injury to the abdominal wall creating a lateral abdominal hernia. Injury to abdominal wall musculature may take months to develop into a clinically apparent hernia. Flank hernias can be successfully repaired using a robotic minimally invasive approach. CONCLUSION: Flank bulge and hernias must be included or at least be considered as consequence of a potential complication from endoscopic colonic perforation. Surgeons and endoscopists must be aware of this potential complication and its latent presentation. This case stresses the importance of long-term outcomes monitoring, particularly with innovative procedures.

[Management of lateral abdominal wall hernias]. / Management der lateralen Bauchwandhernien.

Lateral abdominal wall hernias are rare and inconsistently defined, which is why the use of the European Hernia Society classification makes sense, not least for the purpose of comparing the quality of surgical results. A distinction must be made between true fascial defects and denervation atrophy. Based on the available literature, there is generally a low level of evidence with no consensus on the best operative strategy. The proximity to bony structures and the complex anatomy of the three-layer abdominal wall make the technical treatment of lateral hernias difficult. The surgical variations include laparoendoscopic, robotic, minimally invasive, open or hybrid approaches with different mesh positions in relation to the layers of the abdominal wall. The extensive preperitoneal mesh reinforcement open, transabdominal peritoneal (TAPP) laparoscopic repair or total extraperitoneal (TEP) endoscopic repair has met with the greatest approval. The extent of the required medial mesh overlap is determined by the distance between the medial defect boundary and the lateral edge of the straight rectus abdominus muscles. The medially directed preperitoneal and retroperitoneal dissection can be extended into the homolateral retrorectus compartment by laterally incising the posterior rectus sheath or by crossing the midline behind the intact linea alba into the contralateral retrorectus compartment. The intraperitoneal onlay mesh (IPOM) technique is a suitable procedure only for smaller defects with possible defect closure but it is also important as an exit strategy in the case of a defective peritoneum. Individualized prehabilitative and preconditioning measures are just as important as the assessment of preoperative anamnestic and clinical findings and risks with radiographic cross-sectional imaging diagnostics.

Transabdominal Partial Extraperitoneal Repair of Lateral Hernias of the Abdomen and Flank.

Background: Lateral hernia (LH) repair is a challenging and debated topic in abdominal wall surgery because of the anatomical location and mesh placement and fixation. Large LHs should be managed with an open procedure; however, there is no consensus regarding the repair of small- to medium-sized LHs. We report our treatment of this type of LH using the transabdominal partial extraperitoneal (TAPE) technique. Methods: After retrospective review of the prospective hernia database at two hernia centers, patients with small- to medium-sized LHs who underwent the TAPE technique were identified and analyzed. The key components of our technique include wide dissection of peritoneum off the defect and use of that peritoneum to cover the lower and medial part of the mesh as much as possible. The parameters studied included patient demographics, intraoperative data, and postoperative outcome. Results: We studied 19 patients with small- to medium-sized LHs repaired using the TAPE procedure between 2017 and 2020. LH etiologies were primary hernia (n = 3), incisional hernia (n = 15), and traumatic hernia (n = 1). Mean defect size was 5.8 ± 2.1 cm (range 2.5-10 cm), mean operative time 118.1 ± 41.7 minutes (range 65-240 minutes), and mean postoperative stay 6.4 ± 2.0 days (range 6-9 days). There were no perioperative complications. At a mean follow-up of 20 months, no patient had recurrence of LH. Discussion: For small- to medium-sized LHs, the laparoscopic TAPE technique is minimally invasive and safe; the procedure is associated with minimal postoperative complications.

Repair of lumbar incisional hernia using polypropylene mesh strip sutures - A case report.

INTRODUCTION: Lumbar hernias are considered rare and they constitute less than 1.5% of all abdominal wall hernias. CASE REPORT: Here we present a case of a 72-year-old female with a left flank swelling since 2-years diagnosed as a lumbar incisional hernia. This lumbar incisional hernia1 was repaired successfully using polypropylene mesh strip sutures.2 DISCUSSION: Many surgical techniques have been described for repair of LIH. Suture repair, mesh repair and myofascial flaps have been described for lumbar hernias. Repairing a lumbar hernia can be surgically challenging because of its proximity to bony structures, which can limit proper dissection and mesh overlap. We performed defect closure with PMSS. Patient has no recurrence after 2 years of follow up. CONCLUSION: In our case of left lumbar incisional hernia, defect closure with PMSS was an effective operation. This technique may also be effective in potentially contaminated settings due to reduced implant load. Further studies are required to understand its biomechanics and long-term outcomes.

Totally endoscopic sublay (TES) repair for lateral abdominal wall hernias: technique and first results.

BACKGROUND: The optimal surgical treatment for lateral hernias of the abdominal wall remains unclear. The presented prospective study assesses for the first time in detail the clinical value of a totally endoscopic sublay (TES) technique for the repair of these hernias. METHODS: Twenty-four consecutive patients with a lateral abdominal wall hernia underwent TES repair. This technique is naturally combined with a transversus abdominis release maneuver to create a sufficient retromuscular/preperitoneal space that can accommodate, if necessary, a giant prosthetic mesh. RESULTS: The operations were successful in all but one patient who required open conversion because of dense intestinal adhesion. The mean defect width was 6.7 ± 3.9 cm. The mean defect area was 78.0 ± 102.4 cm2 (range 4-500 cm2). The mean mesh size used was 330.2 ± 165.4 cm2 (range 108-900 cm2). The mean operative time was 170.2 ± 73.8 min (range, 60-360 min). The mean visual analog scale score for pain at rest on the first day was 2.5 (range 1-4). The average postoperative stay was 3.4 days (range 2-7 days). No serious complications (Dindo-Clavien Grade 2-4) were seen within a mean follow-up period of 13.3 months. CONCLUSIONS: A totally endoscopic technique (TES) for the treatment of lateral hernias is described. The technique revealed to be reliable, safe and cost-effective. The first results are promising, but larger studies with longer follow-up periods are recommended to determine the real clinical value.

An extraperitoneal approach for complex flank, iliac, and lumbar hernia.

PURPOSE: The aim of this paper is to propose our four-step technique, an open extraperitoneal approach for complex flank, lumbar, and iliac hernias. METHODS: A big polypropylene mesh is placed, covering and reinforcing all the lateral abdominal wall in an extraperitoneal space. Its borders are retroxiphoid fatty triangle and the costal arch cranially and the retropubic space caudally, psoas muscle, and paravertebral region posteriorly and contralateral rectus muscle medially. Mesh dimensions do not depend from the defect size, but prosthesis has to cover all the lateral abdominal wall. RESULTS: No major complications have been reported. The mean length of stay is 4.8 days (range 3-11). Mean follow-up is 44.8 months (range 5-92). One recurrence (4.5%) has been reported at the 1-year clinical evaluation. CONCLUSION: In conclusion, we believe that regardless size and location of the defect, every complex lateral hernia requires the same extensive repair because of the critical anatomy of the region with a big medium-heavyweight polypropylene mesh placed in an extraperitoneal plane, the only one that allows adequate covering of the visceral sac. Our technique is a safe, feasible, and reproducible treatment for this challenging surgical problem.

Management of lateral abdominal hernias.

PURPOSE: Lateral abdominal wall hernias are rare defects but, due to their location, repair is difficult, and recurrence is common. Few studies exist to support a standard protocol for repair of these lateral hernias. We hypothesized that anchoring our repair to fixed bony structures would reduce recurrence rates. METHODS: A retrospective review of all patients who underwent lateral hernia repair at our institution was performed. RESULTS: Eight cases (seven flank and one thoracoabdominal) were reviewed. The median defect size was 105 cm2 (range 36-625 cm2). The median operative time was 185 min (range 133-282 min). There were no major complications. One patient who was repaired without mesh attachment to bony landmarks developed a recurrence at ten months and subsequently underwent reoperation. Patients with mesh secured to bony landmarks were recurrence free at a median follow-up of 171 days. CONCLUSIONS: Lateral hernias present a greater challenge due to their anatomic location. An open technique with mesh fixation to bony structures is a promising solution to this complex problem.

Etiology of Inguinal Hernias: A Comprehensive Review.

BACKGROUND: The etiology of inguinal hernias remains uncertain even though the lifetime risk of developing an inguinal hernia is 27% for men and 3% for women. The aim was to summarize the evidence on hernia etiology, with focus on differences between lateral and medial hernias. RESULTS: Lateral and medial hernias seem to have common as well as different etiologies. A patent processus vaginalis and increased cumulative mechanical exposure are risk factors for lateral hernias. Patients with medial hernias seem to have a more profoundly altered connective tissue architecture and homeostasis compared with patients with lateral hernias. However, connective tissue alteration may play a role in development of both subtypes. Inguinal hernias have a hereditary component with a complex inheritance pattern, and inguinal hernia susceptible genes have been identified that also are involved in connective tissue homeostasis. CONCLUSION: The etiology of lateral and medial hernias are at least partly different, but the final explanations are still lacking on certain areas. Further investigations of inguinal hernia genes may explain the altered connective tissue observed in patients with inguinal hernias. The precise mechanisms why processus vaginalis fails to obliterate in certain patients should also be clarified. Not all patients with a patent processus vaginalis develop a lateral hernia, but increased intraabdominal pressure appears to be a contributing factor.
