A comparative study on effects of defect closure versus non-closure in laparoscopic totally extraperitoneal repair of direct inguinal hernia

Introduction

Totally extraperitoneal (TEP) and transabdominal preperitoneal (TAPP) repair are the principal techniques in laparoscopic hernia repair. Seroma formation and pain are frequent complications of moderate-large size laparoscopic direct inguinal hernia mesh repair. This study was conducted to evaluate the feasibility of defect closure in moderate-large direct inguinal hernias and its effect on various outcomes.

Method

This is a prospective cohort study from September 2020 to August 2021, where a total of 88 patients with uncomplicated direct inguinal hernia (M3 or more) were enrolled in the study and divided into two equal groups of TEP defect closure and non-closure, and various outcome measures were noted.

Results

The majority of patients were male (94.31%), with a mean age range of 18-85 years, and had right-sided inguinal hernia (46.5%). Seroma formation at 10th POD in the defect closure and non-closure were 24% and 33% (p value: 0.225), which reduced to 11% and 18%, respectively, at 1 month (p value: 1.000). All seromas resolved within 6 months. Pain in VAS at 10th POD in the defect closure and non-closure were 1.55±0.571 and 1.38±0.527, respectively (p value: 0.121), which gradually decreased to 1.20±0.524 and 1.16±0.420 at a 6-month interval (p value: 0.689). The mean operative time in the bilateral and unilateral defect closure groups was 72.3±4.1 and 56.5±4.3 min, respectively, whereas that in the bilateral and unilateral defect non-closure groups was 62.3±3.7 and 45.7±3.6 min, respectively.

Conclusion

The defect closure was found to have higher pain and less seroma formation at various intervals of time following TEP for moderate-large direct inguinal hernia. Although these findings were statistically insignificant, they may be clinically significant, and further studies with a larger sample size are suggested.

QUALITY OF LIFE USING EURAHS-QoL SCORES AFTER SURGICAL TREATMENT OF INGUINAL HERNIA: LAPAROSCOPIC TRANSABDOMINAL PREPERITONEAL (TAPP) AND LICHTENSTEIN TECHNIQUES

BACKGROUND

Results on quality of life after inguinal hernia surgery, such as esthetics, postoperative pain, period of absence from activities, and recurrence are a relevant topic since inguinal hernia affects 27% of men and 3% of women at some point in their lives, and should guide health policies to allocate resources more efficiently.

AIMS

To evaluate the quality of life in the late postoperative period of inguinal herniorrhaphy regarding recurrence, pain, esthetics, and restriction in activities, comparing the minimally invasive techniques - the transabdominal preperitoneal (TAPP) and the conventional Lichtenstein.

METHODS

A cross-sectional observational clinical study was conducted with the EuraHS-QoL questionnaire validated and translated into Portuguese, applied to patients after an average of 65 months postoperatively. Forty-five patients were assessed, 28 undergoing Lichtenstein and 17 undergoing TAPP. All were males aged between 18 and 87 years with a primary unilateral inguinal hernia. Recurrent or bilateral hernias, other concomitant abdominal wall hernias, patients who chose not to participate or who were not found, and female patients were excluded from the study.

RESULTS

Regarding the domains pain, restriction, and esthetics, there was no difference between the two groups when examining quality of life. Neither group presented recurrence in the studied period.

CONCLUSIONS

Both TAPP and Lichtenstein techniques presented similar results concerning quality of life when compared in the long-term.

The Relationship Between Small Peritoneal Flap Defects and Postoperative Seroma in TAPP Repair of Inguinal Hernias

OBJECTIVE

Total abdominal preperitoneal (TAPP) is one of the most frequently used surgical treatment methods in the treatment of inguinal hernia (IH). One of the most common early postoperative complications after hernia repair is seroma/hematoma. In this study, we aimed to study the role of unclosed peritoneal flap defects on the development of postoperative seroma.

MATERIAL AND METHODS

The study was performed retrospectively in 2 university hospitals. All patients over the age of 18 years who underwent laparoscopic TAPP surgery in Istanbul Yeni Yüzyıl University Gaziosmanpaşa Hospital General Surgery Clinic and Van Yüzüncü Yıl University Faculty of Medicine General Surgery Clinic between January 1, 2018, and December 31, 2021, were included. Patients were divided into those with peritoneal defects (group 1) and those without (group 2). Whether there was a peritoneal defect or not was compiled from video recordings. In addition, risk factors affecting the development of seroma were determined.

RESULTS

A total of 250 patients, 16 (6.4%) women and 234 (93.6%) men, were included in the study. There were bilateral hernias in 35 (14%) patients, and a total of 320 hernias were analyzed in the study. It was determined that an American Society of Anaesthesiologists (ASA) III score increased the risk of seroma 15.97 fold (P<0.001, 95% CI, 4.94 to 51.56), direct hernia type increased risk 7.1 fold (P<0.03, 95% CI, 1.204 to 42.422), hernia descending into scrotum increased risk 22.48 fold (P<0.001, 95% CI, 6.66 to 75.84) and closure of the peritoneal flap completely without leaving any defect increased the risk of seroma 8.67 fold (P<0.001, 95% CI, 3.254 to 23.115).

CONCLUSIONS

The presence or leaving of small-diameter defects on the peritoneal flap may reduce seroma development without increasing the risk of complications. Prospective randomized studies are required to reach definitive conclusions.

Non-closure of the Free Peritoneal Flap During Laparoscopic Hernia Repair of Lower Abdominal Marginal Hernia: A Retrospective Analysis

Background: During lower abdominal marginal hernia repair, the peritoneal flap is routinely freed to facilitate mesh placement and closed to conclude the procedure. This procedure is generally called trans-abdominal partial extra-peritoneal (TAPE). However, the necessity of closing the free peritoneal flap is still controversial. This study aimed to investigate the safety and feasibility of leaving the free peritoneal flap in-situ. Methods: A retrospective review was conducted on 68 patients (16 male, 52 female) who underwent laparoscopic hernia repair between June 2014 and March 2021. Patients were diagnosed as the lower abdominal hernia and all required freeing the peritoneal flap during the operation. Patients were divided into 2 groups: one group was TAPE group with the closed free peritoneal flap, another group left the free peritoneal flap unclosed. Analyses were performed to compare both intraoperative parameters and postoperative complications. Results: There were no significant differences in demographic, comorbidity, hernia characteristics and ASA classification. The intra-operative bleeding volume, visceral injury, hospital stay, urinary retention, visual analog scale (VAS) score, dysuria, intestinal obstruction, surgical site infection, mesh infection, recurrence rate and hospital stay were similar among the two groups. Mean operative time of the flap closing procedure was higher than for patients with the free peritoneal flap left in-situ (p = 0.002). Comparisons of postoperative complications showed flap closure resulted in a higher incidence of seroma formation (p = 0.005). Conclusion: Providing a barrier-coated mesh is used during laparoscopic lower abdominal marginal hernia repair, it is safe to leave the free peritoneal flap in-situ and this approach may prevent the occurrence of seromas.

Peritoneal hernia following abdominal hysterectomy: A case report

Background

Internal hernias rarely lead to bowel obstruction; they are caused by a natural or unnatural opening within the peritoneal cavity. Defects in the peritoneum are extremely rare. Patients present with features of intestinal obstruction and most cases are diagnosed during surgery.

Case Presentation

A 47-year-old woman with a history of multiple abdominal surgeries had a small bowel hernia through a peritoneal defect of the anterior abdominal wall. She presented with abdominal pain and distension and was taken to the operating room, where findings revealed an intact fascia and small bowel herniation through a midline peritoneal defect.

Conclusion

Herniation of small bowel through the peritoneum is a rare type of internal hernia that can manifest in a patient with extensive history of abdominal surgeries. This type of clinical picture warrants a high degree of suspicion for prompt and proper management. Surgery should not be delayed, to avoid increased morbidity and mortality.

•

Internal hernias caused by peritoneal defects are very rare.

•

Most cases are diagnosed intraoperatively.

•

Careful closure of peritoneal and/or fascial layers is warranted.

•

Surgery should not be delayed, to avoid increased morbidity and mortality.

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.

Recurrence Rates After Repair of Inguinal Hernia in Women: A Systematic Review

Importance

To our knowledge, a systematic review has not yet been performed that specifically addresses the management of inguinal hernia in women. Recurrence after repair of inguinal hernia is not unusual in women and may be a previously undiagnosed femoral hernia, which is rarely seen in men.

Objective

To investigate rates and types of recurrences in women who had undergone repair of primary inguinal hernia.

Evidence Review

PubMed, Embase, and the Cochrane databases were searched in September 2017 for studies reporting recurrences after repair of primary inguinal hernia in women. Crude rates of recurrence (number of recurrences/number of women) were calculated after open and laparoscopic repairs, and the type of recurrent hernia was registered, if noted in the studies. This review is reported according to the PRISMA guideline.

Findings

A total of 55 studies were included, comprising 43 870 women (mean age, 42-69 years; median age, 57 years). Five studies were randomized clinical trials, 14 were prospective cohort studies, 7 were prospective database studies, and 29 were retrospective cohort studies. Twenty studies reported recurrence after laparoscopic repair, with a crude recurrence rate of 1.2% (27 of 2257) (range, 0%-5%) and a median follow-up of 24 months. Thirty-seven studies reported open repair, with a crude recurrence rate of 2.4% (818 of 33 971) (range, 0%-12.5%) and a median follow-up of 36 months. The crude recurrence rate in randomized clinical trials and prospective studies was 1.2% (18 of 1525) after laparoscopic repair compared with 4.9% (490 of 10 058) after open repair. The recurrent inguinal hernia was a femoral hernia in 203 of 496 patients (40.9%) after open repair, compared with 0% of patients after laparoscopic repair. Recurrence rates were similar when open mesh vs nonmesh techniques were used.

Conclusions and Relevance

Recurrence rates after repair of primary inguinal hernia in women are lower after laparoscopic repair compared with open repair. Intraoperative findings during repair of recurrent inguinal hernia are often femoral hernias in women.
