Background Although laparoscopic inguinal hernia repair was described about 30 years ago and advantages of the technique have been demonstrated, the utilization of this approach has not been what we would expect. Some reasons may be the need for surgeons to understand the posterior anatomy of the groin from a new vantage point, as well as to acquire advanced laparoscopic skills. Recently, however, the introduction of a robotic approach has dramatically increased the adoption of minimally invasive techniques for inguinal hernia repair. Methods Important recent contributions to this evolution have been the establishment of a new concept known as the critical view of the Myopectineal Orifice (MPO) and the description of a new way of understanding the posterior view of the antomy of the groin (inverted Y and the five triangles). In this paper, we describe 10 rules for a safe MIS inguinal hernia repair (TAPP, TEP, ETEP, RTAPP) that combines these two new concepts in a unique way. Conclusions As the critical view of safety has made laparoscopic cholecystectomy safer, we feel that following our ten rules based on understanding the anatomy of the posterior groin as defined by zones and essential triangles and the technical steps to achieve the critical view of the MPO will foster the goal of safe MIS hernia repair, no matter which minimally invasive technique is employed. Keywords Inguinal hernia • Minimally invasive surgery • Laparoscopy • Robotic • Critical view • Golden rules Although laparoscopic inguinal hernia repair was first introduced over 27 years ago as an alternative to conventional open inguinal hernia repairs, the majority of hernias worldwide are still repaired with an open anterior approach [1, 2]. Despite multiple peer-reviewed studies demonstrating that the approach is associated with postoperative benefits and can be safely duplicated by surgeons around the world, the growth of the technique has remained flat until very recently
Background: Laparoscopic inguinal hernia repair has been shown to be superior than open repairs with faster return to daily activities and decrease in the occurrence of chronic pain. However, higher direct costs and mandatory use of general anesthesia are arguments against their use. In addition, increased complexity of surgery resulting from an anatomy that is unusual to general surgeons prevents the widespread adoption of laparoscopic approach. Aim:To propose a technical systematization for transabdominal laparoscopic repair (TAPP) of inguinal hernias based on anatomical concepts. Method:To offer a systematization of TAPP repair based on well defined anatomic landmarks, describing the concept of “inverted Y”, identification of five triangles and three zones of dissection, to achieve the “critical view of safety” for laparoscopic inguinal hernia repair. Results:Since this standardization was developed five years ago, many surgeons were trained following these precepts. Reproducibility is high, as far as, it´s rate of adoption among surgeons. Conclusion: The concept of the “inverted Y”, “Five triangles” and the dissection based in “Three Zones” establish an effective and reproducible standardization of the TAPP technique.
Background:Diastasis of the rectus abdominis muscles (DMRA) is frequent and may be associated with abdominal wall hernias. For patients with redudant skin, dermolipectomy and plication of the diastasis is the most commonly used procedure. However, there is a significant group of patients who do not require skin resection or do not want large incisions. Aim:To describe a “new” technique (subcutaneous onlay laparoscopic approach - SCOLA) for the correction of ventral hernias combined with the DMRA plication and to report the initial results of a case series. Method:SCOLA was applied in 48 patients to correct ventral hernia concomitant to plication of DMRA by pre-aponeurotic endoscopic technique. Results:The mean operative time was 93.5 min. There were no intra-operative complications and no conversion. Seroma was the most frequent complication (n=13, 27%). Only one (2%) had surgical wound infection. After a median follow-up of eight months (2-19), only one (2%) patient presented recurrence of DMRA and one (2%) subcutaneous tissue retraction/fibrosis. Forty-five (93.7%) patients reported being satisfied with outcome. Conclusion:The SCOLA technique is a safe, reproducible and effective alternative for patients with abdominal wall hernia associated with DMRA.
RESUMO As hérnias inguinais são um problema frequente e o seu reparo representa a cirurgia mais comumente realizada por cirurgiões gerais. Nos últimos anos, novos princípios, produtos e técnicas têm mudado a rotina dos cirurgiões que precisam reciclar conhecimentos e aperfeiçoar novas habilidades. Além disso, antigos conceitos sobre indicação cirúrgica e riscos de complicações vêm sendo reavaliados. Visando criar um guia de orientações sobre o manejo das hérnias inguinais em pacientes adultos, a Sociedade Brasileira de Hérnias reuniu um grupo de experts com objetivo de revisar diversos tópicos, como indicação cirúrgica, manejo perioperatório, técnicas cirúrgicas, complicações e orientações pós-operatórias.
Background: Since publication of our paper “Ten Golden Rules for a Safe MIS Inguinal Hernia Repair” we have received many questions. As the authors, we feel it is important to address these topics as a follow-up to our paper. Aim: To discuss in more details the main points of controversy, review the rules and update de recommendations. Method: The questions and discussions came mainly over five rules, numbered 3, 5, 6, 7, 10. We analyzed all the comments about recommendations and update some technical principles. Results: Rule 3 - Removing normal fat plugs from the obturator canal is unnecessary and therefore is not recommended; Rule 5 - transection of the uterine round ligament (1 cm proximal to the deep ring) facilitates adequate dissection. When performed in this way it does not appear to be associated with complications; Rule 6 - transection of huge sacs are safer than over-dissection of the cord structures. Whether dissecting completely the sac or abandon the distal part it results in less postoperative seromas is an ongoing debate; Rule 7 - any retroperitoneal structure traversing the internal ring is or play a role like a hernia. Failing to identify and remove the lipoma will ultimately result in the patient experiencing a recurrence; Rule 10 - in TAPP peritoneum should preferably be closed with suture than tackes. Conclusion: 10 Golden Rules emphasize the most important surgical tips and technical steps that allow the safe performance of MIS repairs of inguinal hernias, regardless the technique.
Abstract. In the present study, we described a rare association of polycystic liver disease (PCLD) with intracranial meningiomas in patients included on a liver transplant list, focusing on the diagnosis, treatment and possible association with any genetic alterations. Two female patients, aged 39 and 49 years were included on a liver transplant list due to extensive PCLD, with symptoms related to an abdominal compartmental syndrome. Screening for extrahepatic manifestation revealed a right frontal meningioma in the first patient, and a parietal posterior calcified meningioma in the second patient, measuring 1 and 7x3x2 cm in diameter, respectively. Following tumor removal, the histological pattern was compatible with fibrous and transitional meningioma, respectively. Cytogenetic studies conducted following surgery did not reveal any changes in metaphase chromosomes. The postoperative follow-up for the two patients was uneventful, without complications, with the patients remaining on a liver transplant waiting list. We conclude that screening for extrahepatic manifestations of PCLD is mandatory, as certain lesions require treatment prior to liver transplantation. The lack of a genetic or familial association between these two cases show they are likely to have occurred by chance, rather than representing a previously unrecognized association between polycystic liver disease and cranial meningioma.
Introduction There has been a great advance in the treatment of inguinal hernias with a significant reduction in recurrences with the use of polypropylene mesh. Local complications such as infections, rejection, and chronic pain are widely studied and reported in the literature. The Autoimmune [Auto-inflammatory] Syndrome Induced by Adjuvants (ASIA) is little known and can be triggered by using polypropylene mesh. Presentation of the case 33-year-old female patient, married, and an administrative manager. History of smoking, previous breast surgery with silicone prosthesis, appendectomy. One year and four months ago, she underwent bilateral inguinal hernioplasty by laparoscopy. Shortly after the inguinal hernia surgery, systemic, urinary symptoms, and chronic local pain appeared. She reported low back pain, fatigue, memory loss, and mood swings associated with limiting pelvic pain, dysuria, and dyspareunia. We performed a robotic surgical procedure to remove the meshes bilaterally. Three days after surgery, the patient was discharged with adequate pain control, without the need for opioids. During outpatient follow-up, there was a significant improvement in symptoms, both local and systemic. Discussion Local complications with the use of polypropylene mesh to repair inguinal hernias are well described in the literature, highlighting chronic postoperative pain that can affect 10–20% of patients. Recently, polypropylene prostheses have been found to act as adjuvants and may be the trigger for an exacerbated immune response adaptive to an autoantigen. Thus, being capable of causing an autoimmune disease variant of the Autoimmune [Auto-inflammatory] Syndrome Induced by Adjuvants (ASIA), described by Shoenfeld and Agmon-Levin in 2011. Conclusion In addition to local complications, systemic symptoms related to the use of polypropylene mesh can also occur. In the Autoimmune [Auto-inflammatory] Syndrome Induced by Adjuvants (ASIA), systemic symptoms, for being nonspecific, make diagnosis difficult and are often not attributed to the use of mesh.
Aim To describe the use of the robotic platform in inguinal hernia recurrence after a previous laparoscopic repair. Material and Methods patients with recurrent inguinal hernias following a laparoscopic repair who have undergone robotic transabdominal preperitoneal between December 2015 through may 2022 were identified in a prospectively maintained database. Outcomes of interest included demographics, hernia characteristics, operative details and rates of 30-day surgical site occurrence (SSO), surgical site occurrences requiring procedural interventions, surgical site infection and hernia recurrence were abstracted. Results thirty patients (96,7% male, mean age 56,5 years, mean body mass index 28) had 41 hernias repaired (N=11 bilateral). Average operative time was 165 ± 51.9min (range 90–300). There were three intraoperative complications all of them were bleeding from the inferior epigastric vessel injuries. Four SSOs occurred (N=3 seromas and N=1 hematoma. After a median 56 months follow-up [IQR 22–77], no recurrence has been diagnosed. One patient developed chronic postoperative inguinal pain. Conclusions on a small number of selected patients and experienced hands, we found that the use of the robotic platform for repair of recurrent hernias after prior laparoscopic repair appears to be safe, feasible and effective despite being technically demanding. Further studies in larger cohorts are necessary to determine if this technique provides any benefits in recurrent inguinal hernia scenario.
