Clinical efficacy of laparoscopic closed hernia ring combined with a patch repair for Gilbert type III indirect inguinal hernia

Purpose

The incidence of seroma and postoperative pain after Gilbert type III inguinal hernia repair is high. To reduce postoperative complications, this study investigated the clinical efficacy of laparoscopic closed hernia ring combined with a patch repair for Gilbert type III indirect inguinal hernia.

Methods

Through a prospective randomized controlled study, a total of 193 patients with Gilbert type III indirect inguinal hernia admitted to Nanchong Central Hospital affiliated with Chuanbei Medical College from May 2020 to December 2021 were selected and randomly divided into the inner ring closed group (85 patients) and the inner ring non-closed group (95 patients). The patients in both groups underwent laparoscopic tension-free repair of their inguinal hernias. General information such as operative time, postoperative hospital stay, and hospital cost were compared between the two groups, and the patients were followed up at 1, 7, 14, 21, and 28 days and then 3, 6, and 12 months after surgery to compare complications such as incidence of seroma, volume of the seroma fluid, incidence of pain, and visual analogue scale (VAS) pain score.

Results

There was no conversion to open procedures in any of the patients. The operation time of the closed group was significantly longer than that of the non-closed group (64.2 ± 12.2 vs. 55.3 ± 9.5 min, P < 0.01). The proportion of patients with postoperative pain in the two groups was 39 (46%) vs. 59 (62%), P = 0.029 on 7 days; 17 (20%) vs. 33 (35%), P = 0.028 on 14 days; and 6 (7%) vs. 22 (23%), P = 0.003 on 21 days in the postoperative closed group and was significantly lower than that in the non-closed group, while we found that the non-closed group had a higher VAS pain score than that of the closed group (2.36 ± 0.61 vs. 1.95 ± 0.71, P = 0.003 on 7 days and 2.12 ± 0.49 vs. 1.65 ± 0.49, P = 0.002 on 14 days) after surgery according to the statistical results of the VAS pain score. The incidence of postoperative seroma and the amount of seroma fluid decreased gradually in both groups, but when comparing the two groups, the proportion of cases of seroma in the closed group on 7 days [45 (53%) vs. 79 (83%), P < 0.01]; 14 days [23 (27%) vs. 43 (45%), P = 0.011]; and 21 days [10 (12%) vs. 29 (31%), P = 0.002] after the operation were significantly less than that in the non-closed group. For the comparison of the amount of seroma fluid between the groups, the seroma fluid volume in the non-closed group was greater than that in the closed group (34.48 ± 20.40 vs. 43.87 ± 16.40 ml, P = 0.006, 7 days) and (21.79 ± 8.42 vs. 30.74 ± 10.39 ml, P = 0.002, 14 days) after surgery. There were no differences in the length of stay, total hospital costs, or postoperative complications (urinary retention, intestinal obstruction, nausea, vomiting, bleeding, and infection) between the two groups, and the differences were not statistically significant (P > 0.05). The postoperative follow-up period was 3-20 months, and no chronic pain or recurrence occurred during the postoperative follow-up period in either group.

Conclusions

Closure of the hernia ring is safe and effective for laparoscopic hernia repair for Gilbert type III inguinal hernia, and it significantly reduces the incidence of postoperative seroma and further reduces the postoperative pain without increasing the risk of postoperative infection and recurrence.

The characteristics of the urogenital fascia in the retrorectal space based on male cadaveric dissection and its clinical application

BACKGROUND

The architecture of retrorectal fasciae is complex, as determined by different anatomical concepts. The aim of this study was to examine the anatomical characteristics of the inferomedial extension of the urogenital fascia (UGF) involving the pelvis to explore its relationship with the adjacent fasciae. Furthermore, we have expounded on the clinical application of UGF.

METHOD

For our study, we examined 20 adult male pelvic specimens fixed in formalin, including 2 entire pelvic specimens and 18 semipelvic specimens. Our department has performed 466 laparoscopic rectal cancer procedures since January 2020. We reviewed the surgical videos involving UGF preservation and analyzed the anatomy of the UGF.

RESULTS

The bilateral hypogastric nerves ran between the visceral and parietal layers of the UGF. The visceral fascia migrated ventrally at the fourth sacral vertebra, which formed the rectosacral fascia together with the fascia propria of the rectum; the parietal layer continually extended to the pelvic diaphragm, terminating at the levator ani muscle. At the third to fourth sacral vertebra level, the two layers constituted the lateral ligaments.

CONCLUSION

The double layers of the UGF are vital structures for comprehending the posterior fascia relationship of the rectum. The upper segment between the fascia propria of the rectum and the visceral layer has no evident nerves or blood vessels and is regarded as the " holy plane" for the operation.

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.

Internal Ring Defect Closure Technique in Laparoscopic Mesh Hernioplasty for Indirect Inguinal Hernia

Purpose

The best way to reduce seroma formation after laparoscopic indirect hernia repair is debated. We noticed that internal ring defect closure in laparoscopic mesh hernioplasty could provide promising outcomes with an effect on diminishing seroma formation. We introduce our closure technique and report our experience.

Methods

This prospective study was conducted from May 2019 to May 2021. Patients with European Hernia Society classification L3 indirect or scrotal hernia were recruited and underwent laparoscopic transabdominal patch plasty (TAPP). Hernia defect closure was performed before mesh deployment. The primary outcomes were seroma formation, postoperative pain, and hernia recurrence. Perioperative data and postoperative complications were also recorded.

Results

Consecutive 77 patients with 89 indirect hernias (including 51 scrotal hernias) were recruited in two regional tertiary hospitals. All operations were successful without open conversion. The mean size of the hernia defect was 3.7 ± 0.5 cm (range, 2.5–5.0 cm). The mean operative time for each hernia repair (peritoneum to peritoneum) was 48.3 ± 10.8 min (range, 33–72 min), and the mean time required for internal ring closure was 6.7 ± 2.2 min (range, 4–10 min). Intraoperative bleeding was minimal. The mean visual analog scale pain score at rest on the first postoperative day was 2.2 (range, 1–4). The average postoperative length of hospital stay was 18 h (range, 14–46 h). During a mean follow-up period of 9.4 months (range, 3–23 months), no hernia recurrence or chronic pain were noted. Seroma formation was detected on six sides of unilateral hernias (6.7%) on postoperative day 7, with a mean volume of 45.8 ml (range, 24–80 ml). All seromas were mild and resolved spontaneously within 3 months, with no need for evacuation or other treatment and without major impact on the final outcome.

Conclusions

Defect closure in laparoscopic mesh hernioplasty for large indirect hernias is safe and feasible and can significantly reduce postoperative seroma formation and relative complications. This approach is recommended in large indirect or scrotal hernia repair.

Embryonic developmental process and clinical anatomy of the preperitoneal fascia and its clinical significance

PURPOSE

Many researchers have different views on the origin and anatomy of the preperitoneal fascia. The purpose of this study is to review studies on the anatomy related to the preperitoneal fascia and to investigate the origin, structure, and clinical significance of the preperitoneal fascia in conjunction with previous anatomical findings of the genitourinary fascia, using the embryogenesis of the genitourinary system as a guide.

METHODS

Publications on the preperitoneal and genitourinary fascia are reviewed, with emphasis on the anatomy of the preperitoneal fascia and its relationship to the embryonic development of the genitourinary organs. We also describe previous anatomical studies of the genitourinary fascia in the inguinal region through the fixation of formalin-fixed cadavers.

RESULTS

Published literature on the origin, structure, and distribution of the preperitoneal fascia is sometimes inconsistent. However, studies on the urogenital fascia provide more than sufficient evidence that the formation of the preperitoneal fascia is closely related to the embryonic development of the urogenital fascia and its tegument. Combined with previous anatomical studies of the genitourinary fascia in the inguinal region of formalin-fixed cadavers showed that there is a complete fascial system. This fascial system moves from the retroperitoneum to the anterior peritoneum as the preperitoneal fascia.

CONCLUSIONS

We can assume that the preperitoneal fascia (PPF) is continuous with the retroperitoneal renal fascia, ureter and its accessory vessels, lymphatic vessels, peritoneum of the bladder, internal spermatic fascia, and other peritoneal and pelvic urogenital organ surfaces, which means that the urogenital fascia (UGF) is a complete fascial system, which migrates into PPF in the preperitoneal space and the internal spermatic fascia in the inguinal canal.

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.

Fascinating history of groin hernias: Comprehensive recognition of anatomy, classic considerations for herniorrhaphy, and current controversies in hernioplasty

Groin hernias include indirect inguinal, direct inguinal, femoral, obturator, and supravesical hernias. Here, we summarize historical turning points, anatomical recognition and surgical repairs. Groin hernias have a fascinating history in the fields of anatomy and surgery. The concept of tension-free repair is generally accepted among clinicians. Surgical repair with mesh is categorized as hernioplasty, while classic repair without mesh is considered herniorrhaphy. Although various surgical approaches have been developed, the surgical technique should be carefully chosen for each patient. Regarding as interesting history, crucial anatomy and important surgeries in the field of groin hernia, we here summarized them in detail, respectively. Points of debate are also reviewed; important points are shown using illustrations and schemas. We hope this systematic review is surgical guide for general surgeons including residents. Both a skillful technique and anatomical knowledge are indispensable for successful hernia surgery in the groin.

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

Groin hernias include indirect inguinal, direct inguinal, and femoral hernias. Obturator and supravesical hernias appear very close to the groin. High-quality repairs are required for groin hernias. The concept of "tension-free repair" is generally accepted, and surgical repairs with mesh are categorized as "hernioplasties". Surgeons should have good knowledge of the relevant anatomy. Physicians generally focus on the preperitoneal space, myopectineal orifice, topographic nerves, and regional vessels. Currently, laparoscopic surgery has therapeutic potential in the surgical setting for hernioplasty, with laparoscopic transabdominal preperitoneal (TAPP) repair appearing to be a powerful tool for use in adult hernia patients. TAPP offers the advantages of accurate diagnoses, repair of bilateral and recurrent hernias, less postoperative pain, early recovery allowing work and activities, tension-free repair of the preperitoneal (posterior) space, ability to cover obturator hernias, and avoidance of potential injury to the spermatic cord. The disadvantages of TAPP are the need for general anesthesia, adhering to a learning curve, higher cost, unexpected complications related to abdominal organs, adhesion to the mesh, unexpected injuries to vessels, prolonged operative time, and as-yet-unknown long-term outcomes. Both technical skill and anatomical familiarity are important for safe, reliable surgery. With increasing awareness of the importance of anatomy during TAPP repair, we address the skills and pitfalls during laparoscopic TAPP repair in adult patients using illustrations and schemas. We also address debatable points on this subject.

Primary unilateral not complicated inguinal hernia: our choice of TAPP, why, results and review of literature

BACKGROUND

Currently, three different techniques are favored for repair of an inguinal hernia: (1) The suture repair described by Shouldice. (2) An open mesh repair according to Lichtenstein. (3) Laparo-endoscopic techniques TAPP and TEP. The aim of the presented paper was to describe the ranking of the Transabdominal Preperitoneal Patch Plasty (TAPP) in comparison to the other techniques for inguinal hernia repair.

METHODS

The manuscript is based on the experiences gained in more than 15,000 TAPPs and numerous own studies as well. The technique of TAPP is described in detail and also the results which can be achieved with special reference to primary unilateral inguinal hernias in male patients. Moreover, a systematic review of the literature is done for the comparison with the other techniques.

RESULTS

According to own experiences, 98% of all patients with an inguinal hernia admitted for surgery to Marienhospital Stuttgart could be operated on using the TAPP technique. The recurrence rate and the rate of severe chronic pain in this setting were below 1%. Due to the limited quality of most of the published studies an evidence-based comparison which is the best of the currently most recommended techniques is questionable. Therefore, when comparing TAPP with TEP, no definite conclusion about superiority of one technique over the other is possible. Both techniques are safe and effective if properly performed. The guidelines recommend that the surgeon should use the technique he had learned best and is familiar with. The comparison between TAPP and the Shouldice repair shows less pain and a higher effectivity after TAPP. The recurrence rate after Lichtenstein repair and after TAPP is similar, but pain and recovery time are significantly less after TAPP.

CONCLUSION

Analyzing the own abundant experiences and the reports in the literature, the TAPP technique has the potential to become the standard operative technique for repair of inguinal hernias in future. However, due to the low level of evidence of most of the studies definite conclusions are difficult to draw at this point of time.
