The femoral hernia: an ideal approach for the transabdominal preperitoneal technique (TAPP)

Diagnosis and Treatment of Inguinal Hernias after Surgical Treatment of Prostate Cancer, Current State of the Problem

(1) Purpose: To compare and evaluate the immediate and long-term results of the use of various hernioplasties for the treatment of inguinal hernias after surgical treatment of prostate cancer; to determine the possibility of performing transabdominal preperitoneal (TAPP) hernioplasty and total extraperitoneal (eTEP) hernioplasty in patients with inguinal hernia during surgical treatment of prostate cancer. (2) Method: This study is a clinical analytical prospective study, without the use of randomization. The study included 220 patients with inguinal hernia, who were randomly divided into two groups (group A (n = 100) and group B (n = 120)). Patients in group A received eTEP, and those in group B received TAPP. The end points of the study were the results associated with the operation itself and the prognosis of the disease in the two groups. (3) Results: Group A: five patients had a scrotal hematoma, in 10 cases nosocomial pneumonia or infectious complications from the postoperative wound. The overall rate of early postoperative complications was 15%. In group B, the following postoperative complications were reported: one case of intestinal injury, six cases of acute urinary retention, eight cases of scrotal hematoma and 12 cases of nosocomial pneumonia or infectious complications from the postoperative wound were admitted. The overall incidence of early postoperative complications was 22.5%. There was no statistically significant difference in the incidence of postoperative complications between the two groups (χ2 (3) = 2.54, p > 0.05). (4) Conclusion: During the analysis of the obtained results, no statistically significant difference was found in the duration of hospitalization, the volume of blood loss, the severity of pain syndrome, postoperative complication incidence and recurrence incidence (p > 0.05); however, the comparison groups differed in the duration of the operation: the operation time in group A was much longer compared to group B (p < 0.05).

FEMORAL HERNIA: UNCOMMON, BUT ASSOCIATED WITH POTENTIALLY SEVERE COMPLICATIONS

BACKGROUND

Although the laparoscopic access is becoming the preferable treatment for femoral hernia, there are only few studies on this important subject.

AIM

To assess the outcomes of the totally extraperitoneal laparoscopic (TEP) access in the treatment of femoral hernia.

METHODS

Data of 62 patients with femoral hernia who underwent herniorrhaphy were retrospectively reviewed. The diagnosis of femoral hernia was established by clinical and/or imaging exams in 55 patients and by laparoscopic findings in seven.

RESULTS

There were 55 (88.7%) females and 7 (11.3%) males, with female to male ratio of 8:1. The mean age was of 58.9±15.9 years, ranging from 22 to 92 years. Most patients (n=53; 85.5%) had single hernia and the remaining (n=9; 14.5%) bilateral, making a total of 71 hernias operated. Prior lower abdominal operations were recorded in 21 (33.9%) patients. Conversion to laparoscopic transabdominal preperitoneal procedure was performed in four (6.5%). Open herniorrhaphy was needed in two (3.2%), one with spontaneous enterocutaneous fistula in the groin region (Richter's hernia) and the another with incidental perforation of the adjacent small bowel that occurred during dissection of hernia sac. There was no mortality.

CONCLUSION

Femoral hernia is uncommon, and it may be associated with potentially severe complications. Most femoral hernias may be successfully treated with totally extraperitoneal laparoscopic access, with low conversion and complication rates.

Case of Incarcerated Femoral Hernia Treated with Laparoscopic Surgery after Groin Hernia Repair

An 81-year-old man was brought to our hospital due to a suspicion of left incarcerated femoral hernia. He was previously diagnosed with incarcerated left groin hernia and was treated using the mesh plug method 1 month back at another hospital. Abdominal computed tomography scan revealed small bowel obstruction, incarcerated bowel, and compression of the left femoral vein. Thus, the patient was diagnosed with incarcerated femoral hernia. An emergency laparoscopic surgery was then performed, and we found that the small bowel was incarcerated into the let femoral ring and was necrotic. However, there was no recurrence of left inguinal hernia. The small necrotic bowel was resected and the femoral ring was repaired. The patient was discharged 8 days after the surgery, and there was no recurrence of femoral hernia after 1 year.

Mini-mesh and Lichtenstein repair compared with a modified Kugel technique for femoral hernia: a randomised controlled trial

INTRODUCTION

A modified Kugel patch is more expensive than ordinary mesh and demands a wide dissection of the preperitoneal space in femoral hernia repair. We therefore adopted a novel method using mini-mesh and a Lichtenstein repair. This study compared mini-mesh and Lichtenstein repair with a modified Kugel technique in patients with a primary unilateral femoral hernia.

METHODS

Patients with unilateral femoral hernia were assigned randomly to undergo mini-mesh and Lichtenstein repair (M group) or modified Kugel repair (K group), followed-up at one week, three months, one year and two years. Demographics, hernia characteristics and operative outcomes of two groups were analysed.

RESULTS

A total of 48 patients in the K group and 49 participants in the M group completed follow-up. The operation time for the M group (68.6 ± 13.4 minutes) was significantly shorter than that of the K group (80.6 ± 10.1 minutes; p=0.030). There was no significant difference between the two groups for chronic pain, foreign body feeling and quality of life, and no recurrence occurred.

CONCLUSIONS

Mini-mesh and Lichtenstein repairs have reasonable results in the patients with femoral hernia in this study, with a reduced operation time compared with a modified Kugel repair. The trial was registered with the Chinese Clinical Trials Registry: ChiCTR1900022264.

Laparoscopic Treatment of an Incarcerated Meckel's Diverticulum in a Femoral Hernia

Meckel's diverticulum (MD) is the persistence of the omphalomesenteric duct. It is usually asymptomatic but may present with bleeding, infections, and intestinal obstruction. It also may be a content of a hernia sac, a so-called Littre hernia. Herein, we will present the case of a 75-year-old female, who suffered from a painful swelling of the right inguinal region. Ultrasound imaging detected an inguinal hernia with incarcerated blind ending small bowel. Immediately, a laparoscopy was conducted. We diagnosed a right femoral hernia with an incarcerated MD. A TAPP (transabdominal preperitoneal) procedure was performed and the MD tangential stapled. Due to an uneventful postoperative course, the patient left the hospital after two days. An incarceration of a MD in a femoral hernia is rare. Tangential resection of the MD with simultaneous hernia repair in a TAPP technique seems to be a sufficient approach, when it is conducted by an experienced surgeon.

Groin Hernias in Women-A Review of the Literature

Background: To date, there are few studies and no systematic reviews focusing specifically on groin hernia in women. Most of the existing knowledge comes from registry data. Objective: This present review now reports on such findings as are available on groin hernia in women. Materials and Methods: A systematic search of the available literature was performed in September 2018 using Medline, PubMed, Google Scholar, and the Cochrane Library. For the present analysis 80 publications were identified. Results: The lifetime risk of developing a groin hernia in women is 3-5.8%. The proportion of women in the overall collective of operated groin hernias is 8.0-11.5%. In women, the proportion of femoral hernias is 16.7-37%. Risk factors for development of a groin hernia in women of high age and with a positive family history. A groin hernia during pregnancy should not be operated on. The rate of emergency procedures in women, at 14.5-17.0%, is 3 to 4-fold higher than in men and at 40.6% is even higher for femoral hernia. Therefore, watchful waiting is not indicated in women. During surgical repair of groin hernia in females the presence of a femoral hernia should always be excluded and if detected should be repaired using a laparo-endoscopic or open preperitoneal mesh technique. A higher rate of chronic postoperative inguinal pain must be expected in females. Conclusion: Special characteristics must be taken into account for repair of groin hernia in women.

Proportion of femoral hernia repairs performed for recurrence in the United States

PURPOSE

Recurrence rates after femoral hernia repair (FHR) have not been reliably established in the USA. We sought to determine this trend over time.

METHODS

The proportion of primary and recurrent FHRs was determined for patients age ≥ 18 from: ACS-NSQIP (1/2005-12/2014), Premier (1/2010-09/2015), and institutional (1/2005-12/2014) data. Trends were analyzed using a one-tailed Cochran-Armitage test.

RESULTS

In the NSQIP database, 6649 patients underwent a FHR. In females, the proportion of FHRs performed for recurrence decreased from 14.0% in 2005 to 6.2% in 2014, p = 0.02. In males, there was no change: 16.7-16.1% 2005-2014 (p = 0.18). The Premier database included 4495 FHRs and our institution 315 FHRs. There was no difference for either gender over time in either data source, all p > 0.05.

CONCLUSIONS

The proportion of femoral hernia repairs performed for recurrence in the USA remained relatively constant in males in two large national databases between 2005 and 2015. In females, a decrease was seen in one of the large national databases.

Quality of life and outcomes for femoral hernia repair: does laparoscopy have an advantage?

BACKGROUND

Due to their relative scarcity and to limit single-center bias, multi-center data are needed to study femoral hernias. The aim of this study was to evaluate outcomes and quality of life (QOL) following laparoscopic vs. open repair of femoral hernias.

METHODS

The International Hernia Mesh Registry was queried for femoral hernia repairs. Laparoscopic vs. open techniques were assessed for outcomes and QOL, as quantified by the Carolinas Comfort Scale (CCS), preoperatively and at 1, 6, 12, and 24 months postoperatively. Outcomes were evaluated using the standard statistical analysis.

RESULTS

A total of 80 femoral hernia repairs were performed in 73 patients: 37 laparoscopic and 43 open. There was no difference in mean age (54.7 ± 14.6 years), body mass index (24.2 ± 3.8 kg/m²), gender (60.3 % female), or comorbidities (p > 0.05). The hernias were recurrent in 21 % of the cases with an average of 1.23 ± 0.6 prior repairs (p > 0.1). Preoperative CCS scores were similar for both groups and indicated that 59.7 % of patients reported pain and 46.4 % had movement limitations (p > 0.05). Operative time was equivalent (47.2 ± 21.2 vs. 45.9 ± 14.8 min, p = 0.82). There was no difference in postoperative complications, with an overall 8.2 % abdominal wall complications rate (p > 0.05). The length of stay was shorter in the laparoscopic group (0.5 ± 0.6 vs. 1.3 ± 1.6 days, p = 0.02). Follow-up was somewhat longer in the open group (23.8 ± 10.2 vs. 17.3 ± 10.9 months, p = 0.02). There was one recurrence, which was in the laparoscopic group (3.1 vs. 0 %, p = 0.4). QOL outcomes at all time points demonstrated no difference for pain, movement limitation, or mesh sensation. Postoperative QOL scores improved for both groups when compared to preoperative scores.

CONCLUSION

In this prospective international multi-institution study of 80 femoral hernia repairs, no difference was found for operative times, long-term outcomes, or QOL in the treatment of femoral hernias when comparing laparoscopic vs. open techniques. After repair, QOL at all time-points postoperatively improved compared to QOL scores preoperatively for laparoscopic and open femoral hernia repair. While international data supports improved outcomes with laparoscopic approach for femoral hernia repair, no data had existed prior to this study on the difference of approach impacting QOL. In the setting where recurrence and complication rates are equal after femoral hernia repair for either approach, surgeons should perform the technique with which they are most confident, as the operative approach does not appear to change QOL outcomes after femoral hernia repair.

An alternative anterior tension free preperitoneal patch technique by help of the endoscope for femoral hernia repair

BACKGROUND

Femoral hernias are relatively uncommon and have a higher risk for strangulation and incarceration. We introduce an alternative anterior tension free inlay patch technique by help of the endoscope for femoral hernia repair.

METHOD

Characteristics of patients undergoing femoral hernia repair between March 2006-April 2011 and description of the surgical technique is presented.

RESULTS

We analyzed our experience with this technique in 26 consecutive patients with femoral hernias (1 bilateral, 15 right, 10 left femoral hernia) in 5 year period. Seven of these 26 femoral hernias were recurrent and 2 of them were concomitant with inguinal hernia. Mean operation time was 30.0 ± 12.1 min. Seroma was seen in 2 patients at postoperative 1st week. There were no; hematoma, wound infection and separation of wound edges and early recurrence at postoperative 1st week and 1st month. The mean follow up period was 41.8 ± 18.2 months. All of 22 patients who were contacted were satisfied with the operation. There was no recurrence, chronic pain and foreign body feeling in any patient at the end of the follow-up period.

CONCLUSION

This feasible and safe alternative anterior inlay patch repair might be used in all femoral hernias with the exception of the ones requiring intestinal resection.

Laparoscopic total extraperitoneal repair in femoral hernia without fixation of the mesh

BACKGROUND AND OBJECTIVES

We report on laparoscopic total extraperitoneal repair without fixation of mesh for femoral hernia in 6 patients.

METHODS

During a 3-year period, laparoscopic total extraperitoneal repair of femoral hernia was performed without mesh fixation in 6 patients. The recurrence rate, pain scores, hospital stay, and other morbidity parameters were noted. Pain scores were 1=no pain, 2=mild pain, 3=moderate pain, 4=severe pain, and 5=intolerable pain.

RESULTS

All 6 patients were females and had unilateral hernias. Mean age was 33.8+/-18.6 years, and follow-up ranged from 12 months to 36 months. Four patients were operated on while under spinal anesthesia, and 2 patients were operated on while under general anesthesia. Mean operating time was 29.2+/-10.7 minutes. The mean pain scores 24 hours and the first week after operation were, respectively, 2.33+/-0.52 and 1.33+/-0.52. Mean hospital stay was 1.17+/-0.41 days, and mean days to resumption of normal activities were 8.5+/-2.1 days. No patient had urinary retention or seroma formation in the postoperative period. At follow-up, no hernia had recurred.

CONCLUSIONS

Laparoscopic femoral hernia repair without fixing the mesh is safe, feasible, and associated with minimal morbidity and recurrence rates.

A new minimally invasive technique for the repair of femoral hernia in children: about 13 laparoscopic repairs in 10 patients

BACKGROUND

Femoral hernias in children are rare and often misdiagnosed. The classic treatment is through an open anterior approach. Since the advent of laparoscopic treatment of inguinal hernia in children, laparoscopy has been proposed to offer an accurate diagnosis and treatment, especially in case of recurrent hernia or bilateral disease. This review was undertaken to report our experience with the primary laparoscopic diagnosis and treatment of pediatric femoral hernias and to investigate its safety and feasibility.

METHODS

All cases of pediatric femoral hernia in a consecutive series of children treated laparoscopically for groin hernias in a single institution over a 7-year period (2001-2007) were identified and studied for patient characteristics, presentation, pre- and perioperative findings, details of the operative repair, and postoperative outcome.

RESULTS

Out of a prospectively studied series of 462 laparoscopic pediatric inguinal hernia repairs in 389 patients, 13 femoral hernias were treated in 10 patients (6 boys), with a mean age of 71/2 years (range, 1.7-12). The preoperative diagnosis of femoral hernia was accurate in 7 patients. Seven femoral hernias were exclusively right sided; 3 were bilateral. All 13 femoral hernias were successfully treated by a standardized transabdominal laparoscopic approach with the use of three 3.5-mm trocars. All patients were treated in a day care setting. No postoperative complications occurred. No recurrences were seen until the present time, with a mean follow-up of 31/2 years.

CONCLUSIONS

Laparoscopy provides a straightforward, accurate diagnosis for the rare and often missed pediatric femoral hernias. The new technique described offers a safe and efficient minimally invasive anatomical repair of the crural orifice in children, even when not suspected preoperatively. The laparoscopic diagnosis of 13 femoral hernias from a cohort of 462 laparoscopic groin hernia repairs (2.8%) may suggest a higher prevalence rate of this unusual type of hernia in children than earlier described in literature.

Laparoscopic hernia repair

The laparoscope was first invented in the early 20th century. The first laparoscopic hernia repair was in 1990. Despite almost 20 years of laparoscopic hernia repair experience, open hernia surgery remains the main stay of hernia surgery today. This review looks at current evidence and guidelines on the use of laparoscopic hernia repair surgery.

Laparoscopic management of acutely incarcerated femoral hernia

Incarcerated femoral hernia is a common surgical emergency condition. Diagnosis is always obvious and straightforward by clinical examination, and open surgical repair is the mainstay of treatment. In the era of minimally invasive surgery, laparoscopic repair of femoral hernia has been shown to be feasible and safe. However, laparoscopic repair of acutely incarcerated femoral hernia has gained little discussion in the past. In this paper, we report the results of 8 consecutive cases of strangulated femoral hernia that was successfully managed by the laparoscopic approach.

Femoral hernia repair

Plug insertion for primary femoral hernia repair may cause p.o. discomfort. The Kugel technique may avoid this problem. Patients' satisfaction to the Kugel and the plug techniques is compared in the present study. Demographics, surgical, outcome and analgesic consumption data of 26 patients treated for with the plug technique (P group) are compared with 24 operated with the Kugel patch (K group). Patients' p.o. discomfort to the two procedures was measured with quantitative (VAS score) and a qualitative (the short form of McGill pain questionnaire, SF-MPQ) methods, and compared. P group presented higher early p.o. pain (P<0.001), higher analgesic consumption and a significative delay in the return to physical activity (P<0.001). SF-MPQ scores at p.o. day 8, day 30 and month 6 were significantly lower for K group (P<0.001, P<0.001, P<0.005). The Kugel technique for femoral hernia treatment seems to cause less p.o. discomfort to patients than the plug technique.

Femoral hernia: a review of 83 cases

We evaluate the factors that affect morbidity and mortality in patients who underwent surgery due to femoral hernia. The medical records of 83 patients who underwent femoral hernia repair between January 1996 and June 2004 were retrospectively analyzed. The femoral hernias were repaired either with McVay or mesh plug hernioplasty. Sex, age, surgical repair technique, presence of incarceration/strangulation, incarcerated/strangulated organs, postoperative complications, duration of hospitalization, recurrence rate, and factors that affect mortality and morbidity were studied. There were 83 patients with femoral hernia in our study. Patients' age ranged from 10 to 75 years (mean age was 46.84) with a predominance of female (71%). Thirty-six patients (40%) underwent emergency surgery with the diagnosis of strangulation or incarceration of femoral hernia. Seventeen patients had strangulation and underwent resection; eleven of these patients had omentum in the hernial sac, whereas six patients had intestines. Four of these patients underwent laparotomy. The remaining 19 patients had incarceration and underwent simple reduction of hernial sac content without resection. Forty-seven (60%) patients underwent elective surgery. McVay technique was used for 79 patients, while the other four patients were treated with mesh-plug. Twelve patients (15%) developed a variety of complications (nine patients (25%) in emergency, three patients (6%) in elective group). There was one mortality. Recurrences occurred in two patients. Femoral hernia is an important surgical pathology with high rates of incarceration/strangulation and intestinal resection. Emergency surgery can increase morbidity and mortality especially in the elderly. Early elective surgery may reduce complication.

Is endoscopic totally extraperitoneal hernioplasty justified for the repair of groin hernia in female patients?

BACKGROUND

Groin hernia is an uncommon surgical pathology in females. The efficacy of the endoscopic approach for the repair of female groin hernia has yet to be examined. The current study was undertaken to compare the clinical outcomes of female patients who underwent open and endoscopic totally extraperitoneal inguinal or femoral hernioplasty (TEP).

METHODS

From July 1998 to June 2004, 108 female patients who underwent elective repair of groin hernia were recruited. The patients were divided into TEP (n = 30) and open groups (n = 78) based on the type of operation. Clinical data and outcome parameters were compared between the two groups.

RESULTS

The mean ages and hernia types were comparable between the two groups. All TEPs were successfully performed. The mean operative times were 52 min for unilateral TEP and 51 min for open repair. The difference was not statistically significant. Comparisons of the length of hospital stay, postoperative morbidity, pain score, and time taken to resume normal activities showed no significant differences between the two groups. A single patient in the TEP group experienced recurrence of hernia.

CONCLUSIONS

The findings show equivalent postoperative outcomes after TEP and open repair of groin hernia in female patients. Because the wound scar after open repair is well concealed beneath the pubic hair and no superior clinical benefits are observed after TEP, open repair appears to be the technique of choice for the management of primary groin hernia in females. The TEP approach should be reserved for female patients with recurrent or multiple groin hernia.

Laparoscopic totally extraperitoneal mesh repair for femoral hernia

BACKGROUND

The role of laparoscopic repair for femoral hernia has not been clearly defined, although the advantages of this technique for repair of inguinal hernia are well recognized.

AIM

The aim of this study was to assess the outcome of laparoscopic total extraperitoneal (TEP) repair of femoral hernia.

METHODS

Case records of patients who had laparoscopic TEP repair of femoral hernia between 1994 and 2002 were reviewed retrospectively. Patients' demographic details, presentation, operative details, and follow-up information were gathered from the clinical records. Postoperative complications, chronic pain, and recurrence of the hernia were assessed.

RESULTS

Fifteen patients, 10 males and 5 females, with a mean age of 55 years (range, 33-84 years) underwent laparoscopic TEP femoral hernia repair. Fourteen patients (93.3%) had a primary femoral hernia, and one had a recurrent femoral hernia. In 9 (60%) patients the hernia was irreducible but not obstructed. There were no postoperative complications or chronic pain. One patient (7%) with a small (11 x 6 cm) mesh developed an inguinal recurrence.

CONCLUSION

Laparoscopic TEP repair is a suitable technique for repair of femoral hernia, including irreducible but not obstructed femoral hernias.
