Crucial anatomy and technical cues for laparoscopic transabdominal preperitoneal repair: Advanced manipulation for groin hernias in adults

A novel laparoscopic technique for closing the defect of direct inguinal hernia: How-I-Do-It

PURPOSE

To develop a surgical endoscopy technique for closing the defect of direct inguinal hernia and evaluate the efficacy and safety of a novel suture in the early postoperative period.

METHODS

A prospective randomized controlled single-center study was conducted at Yudin State Clinical Hospital (Moscow) from February to August 2024. We enrolled 142 male patients over 18 with newly diagnosed direct inguinal hernias and a hernia orifice being 1.5-3 cm, who were treated with extended Totally Extraperitoneal Plasty (eTEP) repair. The patients were randomly assigned to two equal groups: a comparison group that underwent hernia defect closure and a control group that did not receive intracorporeal sutures.

RESULTS

On postoperative day 1, ultrasound revealed seromas in 6 patients (11.7%) in the comparison group and in 22 patients (43.1%) in the control group (95% confidence interval [CI] 0.14-0.5, p = 0.05). Mean operation times were 47.25 ± 8.68 for the comparison and 43.63 ± 8.31 min for the control group. Pain intensity on day 2, assessed with a visual analog scale (VAS), was 2.57 ± 1.09 in the comparison group and 2.9 ± 1.29 in the control group, indicating mild to moderate pain. No adverse events occurred in either group 30 days postoperatively.

CONCLUSION

This study presents a novel surgical endoscopy technique for closing direct medial inguinal hernia defects and provides anatomical feasibility. The advantages of the technique include preventing seromas and severe postoperative pain. Further randomized studies are warranted to assess long-term results of this technique and establish clinical indications for its use in surgical practice.

Transabdominal Preperitoneal Repair for an External Supravesical Hernia With an Incarcerated Ovary: A Case Report

External supravesical hernias with ovarian incarceration have not been reported previously. Here, we describe transabdominal preperitoneal (TAPP) repair of an external supravesical hernia with ovarian incarceration. A 68-year-old woman presented to our outpatient clinic with the chief complaint of right inguinal swelling and pain. A 3-cm-diameter mass in the right inguinal region that was difficult to reduce was palpable, and computed tomography (CT) revealed a suspicious lesion of the right hydrocele of the canal of Nuck. Hydrocelectomy was performed through an inguinal incision, and the external inguinal ring was repaired using the Marcy method. The histopathological examination confirmed the diagnosis of the canal of Nuck. Three months postoperatively, the patient again presented with right inguinal pain, and CT revealed a right femoral hernia requiring surgical repair. Intraoperative findings revealed a right external supravesical hernia with an incarcerated ovary, which was laparoscopically reduced and repaired with a mesh. At the three-month follow-up, there were no postoperative complications or recurrences. Incarcerated ovaries with inguinal hernias have been reported in girls; however, incarcerated ovaries with external supravesical hernias have not been reported in women. Although the preoperative diagnosis was difficult to make in this case, the laparoscopic approach led to the diagnosis and successful mesh repair. Although optimal mesh repair of external supravesical hernias using TAPP has not been established, we believe that 2-5 cm around the hernial orifice, the Hesselbach triangle, and the lateral triangle should be covered with mesh.

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.

Therapeutic efficacy of programmed spatial anatomy of the myopectineal orifice in total extraperitoneal hernioplasty: a retrospective study

This study aimed to investigate the therapeutic efficacy of programmed spatial anatomy of myopectineal orifice technique in laparoscopic total extraperitoneal hernioplasty (TEP) surgery. A total of 121 adult male patients with unilateral inguinal hernias who underwent TEP in the Department of General Surgery, Wujin Hospital, affiliated with Jiangsu University, from January 2019 to December 2020 were selected. Patients were divided into the procedural (63 cases) and traditional groups (58 cases) according to the surgical methods adopted. The procedural group underwent programmed spatial anatomy of the myopectineal orifice combined with TEP, and the traditional group underwent traditional TEP. The perioperative evaluation indicators and postoperative complications were observed and compared between the two groups. Compared with the traditional group, the time of handling hernia, the intraoperative operation time, intraoperative blood loss, postoperative ambulation time, and postoperative hospital stay in the procedural group were significantly reduced (P < 0.05). The incidence of postoperative complications such as sensory nerve abnormalities and chronic pain was significantly decreased (P < 0.05), and the total incidence of complications in the procedural group was significantly lower than that in the traditional group (P < 0.05). While there was no significant difference in postoperative incision infection (P > 0.05). The programmed spatial anatomy of the myopectineal orifice can significantly improve the treatment outcome of TEP, significantly improve the patients' intraoperative and postoperative indicators, and reduce the incidence of postoperative complications. It is worthy of being promoted among young physicians and basic hospitals.

Significance of routine preoperative prone computed tomography for predicting intractable cases of inguinal hernias treated by transabdominal preperitoneal repair

Physical examination is the standard diagnostic approach for adult inguinal hernias. We aimed to evaluate the clinical utility of routine preoperative computed tomography scans in the prone position for predicting intractable cases of inguinal hernias before performing transabdominal preperitoneal repairs. We retrospectively analyzed 56 lesions in 48 patients with inguinal hernias who underwent prone computed tomography scans prior to transabdominal preperitoneal repairs. To assess the ability of prone computed tomography to enable the accurate preoperative diagnosis of inguinal hernias, we compared preoperative hernia types as classified through hernia computed tomography and intraoperative diagnosis. We also analyzed the relationship between operation time and hernia type in unilateral cases (n = 40). The overall hernia computed tomography detection and classification accuracy rates were 81.0% and 83.9%, respectively, using the Japan Hernia Society classification system (2009 version) and 84.3% and 91.2%, respectively, using the European Hernia Society classification system. There were no differences in the hernia type frequencies between the shorter (n = 20) and longer (n = 20) operation time groups. Two patients had sliding inguinal hernias with prolapsing bladders, both of which were detectable using preoperative prone computed tomography. Although transabdominal preperitoneal repairs were completed in both cases, the operation times were exceptionally long (185 and 291 minute). Preoperative prone computed tomography is useful for predicting intractable cases of inguinal hernias. Prone computed tomography can play a significant role in not only typing and differentiating hernias from other diseases, but also in helping surgeons appropriately treat unexpected intractable cases with laparoscopic surgery.

The transition from open to laparoscopic surgery for bilateral inguinal hernia repair: how we did it

PURPOSE

To describe the transition process from open repair (OR) to laparoscopic repair (LR) of bilateral inguinal hernia in a small basic general hospital METHODS: We describe the technical details and training strategy used to facilitate the transition to systematic LR of bilateral inguinal hernia. We conducted a retrospective analysis of prospectively collected data from all patients undergoing bilateral inguinal hernia repair between January 2017 and December 2020. We analysed the evolution of LR and compared the surgical outcomes: complications, acute pain (24 h), chronic pain (> 3 months), and recurrence (1 year) of the patients operated on by OR and LR.

RESULTS

We performed 132 bilateral inguinal hernia repairs, 55 (41.7%) ORs, and 77 (58.3%) LRs. A significant difference was observed in the choice of LR over time (2017: 9%, 2018: 32%, 2019: 75%, 2020: 91%, p < 0.001). The mean operative time was shorter in the OR group than in the LR group (56 min vs. 108 min, p < 0.001). However, the operative time of the LR decreased over the years. No significant differences were observed in complications or recurrence. LR was associated with lower acute postoperative pain at 24 h (2.2 vs. 3.1 points, p = 0.021) and lower chronic groin pain than OR (1.3% vs. 12.7%, p = 0.009).

CONCLUSION

A structured and systematized training process made the transition from OR to LR of bilateral inguinal hernias feasible and safe in a small basic general hospital. This transition did not increase complications or recurrence. Additionally, LR was associated with a decrease in postoperative pain and chronic groin pain.

The Preperitoneal Space in Hernia Repair

The preperitoneal spaces relevant for incisional hernia repair and minimally invasive groin hernia repair are described in terms of surgical anatomy. Emphasis is put on the transversalis fascia and the urogenital fascia and its extensions, the vesicoumbilical fascia, and the spermatic sheath of Stoppa procedure. Steps in hernia surgery where these structures are relevant are reviewed.

Robotic hernia surgery I. English version : Robotic inguinal hernia repair (r‑TAPP). Video report and results of a series of 302 hernia operations

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 (r‑TAPP) and illustrates the surgical steps of r‑TAPP with respective video sequences. The results of a cohort study of 302 consecutive hernias operated by r‑TAPP are presented and discussed in light of the added value of the robotic technique, including advantages for surgical training. r‑TAPP 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 r‑TAPP with new parameters.
