Infrascrotal, Perineal, Femorofemoral Bypass for Arterial Graft Infection at the Groin.

HYPOTHESIS: Infrascrotal, perineal, femorofemoral bypass is an acceptable procedure for treating infection of a prosthetic arterial graft limited to a unilateral groin. DESIGN: A consecutive sample clinical study with a mean follow-up of 29 months. SETTING: The surgical department of an academic tertiary care center and an affiliated secondary care center. PATIENTS: Nineteen patients with a mean age of 68 years with prosthetic graft infection at the outflow anastomosis on a femoral artery at the Scarpa triangle underwent an infrascrotal, perineal, femorofemoral bypass, with excision of the graft material limited at the groin. The recipient artery was the profunda femoris artery in 12 cases, the superficial femoral in 5, and the distal common femoral artery in 2. MAIN OUTCOME MEASURES: Cumulative survival, recurrence of sepsis, primary graft patency, and limb salvage rates expressed by standard life-table analysis. RESULTS: Postoperative mortality rate was 5%. Cumulative (SE) survival rate was 65% (11.6%) at 3 years. Cumulative (SE) rate of freedom from recurrent sepsis was 88% (8.6%) at 3 years. Cumulative (SE) primary patency and limb salvage rates were 86% (9.4%) and 91% (7.9%), respectively, at 3 years. CONCLUSION: Femorofemoral bypass with an infrascrotal perineal approach is a valuable procedure for the treatment of femoral arterial graft infection limited at a unilateral groin.

Groin hernias in adults: value of color Doppler sonography in their classification.

PURPOSE: We assessed the abilities of color Doppler and power Doppler sonography to distinguish among types of groin hernias by demonstrating the inferior epigastric artery (IEA) and its relationship with the hernia sac. METHODS: Nineteen consecutive patients (14 men and 5 women), clinically diagnosed as having groin hernias and scheduled to undergo herniorrhaphy, were prospectively enrolled in this study. Ultrasound examinations were performed preoperatively with a 6-12-MHz linear-array transducer. The IEA was identified, if possible, and its relationship to the hernia sac assessed. The sonographic diagnoses were compared with the operative findings. RESULTS: There were 15 indirect inguinal hernias, 4 direct inguinal hernias, and 1 femoral hernia; 1 patient had bilateral inguinal hernias (indirect and direct). In 18 (90%) of 20 hernia cases, the trunk segment of the IEA could be visualized. In 11 (55%) of 20 hernia cases, the origin segment of the IEA could be visualized and its relationship with the hernia sac assessed. In 9 (82%) of the 11 hernia cases, hernia types were correctly diagnosed by sonography. The overall accuracy of sonography for diagnosing the type of hernia was 45% (9 of 20 hernias). CONCLUSIONS: Color Doppler sonography can accurately differentiate types of groin hernias if the origin segment of the IEA and the hernia sac can be visualized simultaneously. However, color Doppler sonography sometimes failed to visualize this segment.

Sports-related groin pain: evaluation with MR imaging.

Our purpose was to assess the role of MRI in evaluating the musculoskeletal system in athletes with chronic pain laterally in the groin of unknown etiology. Magnetic resonance imaging (MRI) of the pubic ring was performed in 11 young athletes (soccer players) with long-standing groin pain. MR findings were compared with plain films and isotope examination (bone scan Tc 99M). Abnormal MRI findings included a broadened and irregular symphysis with a characteristic pattern of low signal intensity on T1W and high signal intensity on T2W images localized in the superior pubic ramus at a distance from the symphysis. Positive findings were also observed on plain films and on nuclear medicine studies. However, the imaging findings in the superior public ramus of the symphysis was located considerably more laterally on MRI. MRI is a valuable method for evaluating discrete and ambiguous pelvic pain in athletes, particularly for identifying concomitant changes in the superior ramus, which may give rise to long-standing pain localized laterally in the groin.

The recurrent groin hernia: therapeutic solutions.

Attention to the problem of groin hernia problems has focused on the primary type of operative repair. Because of this, major advances have been made in the surgical cure of these entities. It is important in the primary operation to individualize the type of operative procedure to the specific hernial problem. The results of treatment of recurrent groin hernia range from very poor to excellent. It appears that the use of prosthetic mesh, particularly if placed in the preperitoneal space, has markedly improved the cure rate for these difficult recurrent groin hernias.

Outcomes in the management of vascular prosthetic graft infections confined to the groin: a reappraisal.

The management of vascular prosthetic graft infections confined to the groin continues to be controversial. To critically evaluate this problem, we reviewed the records of our vascular registry from December 1992 through February 1995 and found 17 incidences of groin sepsis involving a vascular prosthesis in 10 patients. These included a proximal prosthetic femoropopliteal bypass (n = 6), an aortobifemoral graft limb (n = 5), an ileofemoral bypass (n = 3), a prosthetic femoral patch (n = 2), and an aortofemoral/femorofemoral bypass (n = 1). The mean age of these patients was 65 years. Six patients were diabetic, four were on systemic steroids, and two were diabetic and on steroids. All infections were Szilagyi grade III including three in which the patients presented with local hemorrhage. Treatment consisted of irrigation, radical debridement with or without in situ graft replacement, and local rotational muscle flap coverage in nine cases, graft excision with extra-anatomic (obturator ileofemoral bypass) graft replacement in six cases, and excision alone in two cases. Of the 17 infections treated operatively and followed from 1 week to 18 months (median 5 months), eight (47%) showed no evidence of recurrence, six (35%) recurred, two (12%) caused early death, and one resulted in a thrombosed graft requiring extra-anatomic reconstruction. Of the nine infected grafted treated locally with muscle flaps, six showed recurrent infection from 3 weeks to 15 months and one thrombosed for a total local treatment failure rate of 78%. Only two grafts are free of infection at 4 and 5 months, respectively. Of the six incidences of infection treated with obturator bypass, four (66%) are free of infection and two resulted in patient death; both infections treated with excision alone were eradicated but resulted in a major lower extremity amputation. These data question the growing acceptance of debridement and local muscle flap coverage for the treatment of all prosthetic vascular graft infections confined to the groin, especially in patients who are diabetic or on systemic steroids.

Groin dissection in malignant melanoma.

BACKGROUND: There is controversy about the extent of groin dissection necessary (whether superficial or radical) and about its utility when the deep nodes are affected. METHODS: A total of 198 groin dissections (1977-1991) were reviewed; 94 (48%) were superficial and 104 (52%) were radical dissections. Of 72 patients with palpable positive inguinal nodes, 31 (43%) had involvement of the deep nodes; of 39 patients with nonpalpable, histologically positive inguinal nodes, seven (18%) had or later manifested involvement of the deep nodes. RESULTS: The mean number of positive nodes (median) in the group with clinically palpable disease was six (two), and in the group with occult disease the number was two (one). The estimated overall (disease-free) 5-year and 10-year survival rates for patients with negative nodes were 73% (67%) and 64% (58%), respectively, and for those with positive nodes they were 36% (27%) and 30% (23%), respectively. Survival was significantly poorer for patients with positive nodes (p < 0.0001). The respective 5-year and 10-year survival rates for patients with positive nodes and involvement of the inguinal nodes only were 41% (33%) and 36% (29%), and for those with involvement of the inguinal and deep nodes the rates were 28% (17%) and 19% (13%). Survival was significantly poorer for patients with deep node involvement (p = 0.006). CONCLUSIONS: The survival rates after therapeutic groin dissection are substantial and unattainable with any other treatment at the present time. Incontinuity dissection of the deep nodes is advisable in the presence of palpable inguinal nodes, since the incidence of deep node involvement is considerable and the survival rate appreciable after removal of involved deep nodes.

A new method of hernioplasty for adult groin hernias centering on repair of the transversalis fascia.

A new method of hernioplasty for adult groin hernias centering on repair of the transversalis fascia was assessed by a questionnaire conducted every five years on adult patients who had received the above operation. The efficacy of this method was evaluated in terms of the postoperative quality of life and prevention of recurrence of groin hernias. Over the last 9 years, 834 adult patients with 921 groin hernias, including bilateral lesions, have undergone the above procedure and overall, favorable results were obtained, with only one case of recurrence (0.1 per cent) being reported. Contralateral herniation, which has been often reported following Bassini's or Hatakoshi's method, was found in only one of our patients although the number of patients who complained of pain in the operated region was comparatively high, being 51 cases or 11.4 per cent.

Analysis of the SAGES Outcomes Initiative groin hernia database.

BACKGROUND: In 1999, the Society of American Gastrointestinal Endoscopic Surgeons (SAGES) introduced the SAGES Outcomes Initiative as a way for its members to track their own outcomes. It contains perioperative and postoperative data on nearly 20,000 operations. This report provides a descriptive analysis of the groin hernia database. METHODS: The SAGES Outcomes Initiative database was accessed for all groin hernia cases from September 1999 to February 2005. The data from the preoperative, intraoperative, and postoperative entries were summarized. These data are purely descriptive and no statistical analysis was done. RESULTS: The hernia registry contains 1,607 entries, with 1,070 follow-up entries. Males comprised 85% of patients, 63% were employed, 62% had at least one comorbidity, with 84% ASA class I or II. Primary, unilateral hernia accounted for 86% of cases, whereas 14% were recurrent, 11% bilateral, 6% incarcerated, and 3% required emergency repair. The operating surgeon was the attending surgeon in 83% of cases. Anesthetic techniques were general anesthesia in 74% of cases, regional in 7%, and local in 34%, with only 16% of cases local only. Most patients had symptomatic hernias and symptoms were improved in more than 95% of patients. Most repairs were open, although 45% were endoscopic. The most frequently cited postoperative event was significant bruising (6%), with more than 99% of complications being class I or II. More than 95% of patients were able to return to work by the first postoperative visit. Patients who underwent endoscopic repair were reported to have fewer days of narcotic use than patients undergoing open repairs (0 vs 3). CONCLUSIONS: First analysis of the SAGES Outcomes Initiative groin hernia database demonstrates that (a) this is one of the largest prospective; voluntary hernia registries; (b) missing data are infrequent; and (c) the data are similar to published data from national, mandatory registries and randomized trials. Although the SAGES Outcomes Initiative is a voluntary registry, initially designed for surgeon self-assessment, and it therefore has the potential for methodological concerns inherent to voluntary registries, the findings from this first analysis are encouraging. Efforts are ongoing to simplify data entry (PDA), refine data parameters, increase surgeon participation, and determine the role of data audit and thereby the potential for clinical research.

Rotational muscle flap closure for acute groin wound infections following vascular surgery.

Since 1996, 41 patients have presented to our institution with deep but localized groin infection following bypass (30) or isolated femoral artery surgery (11). These patients were treated with antibiotics, debridement, and rotational muscle flap coverage either immediately or within a few days. Patients had one of three patterns: serous leak from a groin incision within a few days of operation (Acute, n = 10), early serous leak that later became grossly infected (Acute-observed, n = 8), or obvious purulent drainage following an initially normal, healed wound (Delayed, n = 23). Patients with early leak had nearly uniformly polymicrobial infections with a preponderance of gram-negative organisms, whereas most of those with late purulence had monobacterial infection with Staphylococcus aureus. At exploration, 26 of 41 suture lines were exposed. Rectus femoris flaps were used in 35 patients (85% of cases) for coverage, and graft preservation was attempted in all 8 vein grafts and 16 of 23 prosthetic grafts. Only one flap failed and there were no instances of anastomotic bleeding. There were no deaths directly attributable to reexploration and flap coverage, although 10 patients died during the index hospitalization. Durable coverage with no long-term evidence of infection was achieved in 24 patients with mean follow-up of 23 (range 10-66) months and another 12 had no evidence of local problems despite shorter follow-up; only 5 patients (12%) overall had evidence of persistent graft infection or unexplained bacteremia. In patients with attempted graft salvage, limb salvage was 97% at 6 months and 85% at 1 year. Although early mortality is high, deaths are not related to the flap procedure itself, local outcome is excellent, and graft and limb salvage are good; results are much worse if an initially draining wound is treated too late. Local rotational muscle flap closure is an excellent solution for acute infections involving the groin following vascular procedures.

Change in the management of adult groin hernia.

Three hundred fifty-seven groin hernia repairs were performed under local anesthesia using a long-lasting local anesthetic agent. An ilioinguinal, iliohypogastric, and twelfth intercostal nerve block was carried out initially, followed by regional infiltration of the agent, using a technic first described by Ponka [8] with several modifications. This technic can be employed suffessfully in the majority of groin hernia repairs. It requires careful attention to detail in the administration of preoperative sedation and analgesia and the use of sharp dissection only and greater gentleness in the handling of tissue. We have observed a significant reduction in postoperative discomfort and the virtual elimination of urinary retention, urinary sepsis, atelectasis, and phlebitis in these cases. All patients are fully ambulatory, without assistance immediately after surgery and the majority are discharged the same day or the following morning. This results in a marked reduction in the total cost of repairing a groin hernia.

Efficacy of dextrose prolotherapy in elite male kicking-sport athletes with chronic groin pain.

OBJECTIVE: To determine the efficacy of simple dextrose prolotherapy in elite kicking-sport athletes with chronic groin pain from osteitis pubis and/or adductor tendinopathy. DESIGN: Consecutive case series. SETTING: Orthopedic and trauma institute in Argentina. PARTICIPANTS: Twenty-two rugby and 2 soccer players with chronic groin pain that prevented full sports participation and who were nonresponsive both to therapy and to a graded reintroduction into sports activity. INTERVENTION: Monthly injection of 12.5% dextrose and 0.5% lidocaine into the thigh adductor origins, suprapubic abdominal insertions, and symphysis pubis, depending on palpation tenderness. Injections were given until complete resolution of pain or lack of improvement for 2 consecutive treatments. MAIN OUTCOME MEASURES: Visual analog scale (VAS) for pain with sports and the Nirschl Pain Phase Scale (NPPS), a measure of functional impairment from pain. RESULTS: The final data collection point was 6 to 32 months after treatment (mean, 17 mo). A mean of 2.8 treatments were given. The mean reduction in pain during sports, as measured by the VAS, improved from 6.3+/-1.4 to 1.0+/-2.4 ( P <.001), and the mean reduction in NPPS score improved from 5.3+/-0.7 to 0.8+/-1.9 ( P <.001). Twenty of 24 patients had no pain and 22 of 24 were unrestricted with sports at final data collection. CONCLUSIONS: Dextrose prolotherapy showed marked efficacy for chronic groin pain in this group of elite rugby and soccer athletes.

The effect of polypropylene mesh on ilioinguinal nerve in open mesh repair of groin hernia.

OBJECTIVES: Repair of groin hernia is one of the most common operations performed by general surgeons, and mesh repair methods have gained wide acceptance. Chronic pain is the most serious long-term complication that can occur after repair of groin hernia. The development of chronic pain after herniorraphy has been attributed to several mechanisms, including damage to sensory nerves and mesh inguinodynia. MATERIAL AND METHODS: Twenty-four rabbits underwent bilateral inguinal dissection and synthetic polypropylene mesh laid on one side. Bilateral inguinal dissection was performed again after 3 months, and samples of nerve tissue were taken from both sides for histological examination. RESULTS: Light microscopic examination of the sections of control group peripheral nerves were in normal appearance, but the nerve fascicles in experimental group operated with mesh showed axonal dilation and mild-to-severe loss of myelinated axons. Examination of semi-thin and ultra-thin sections in control group peripheral nerve fascicles showed normal morphology. Ultrastructural nerve morphology in experimental group operated with mesh exhibited endoneurinal edema with thickening of both endoneurium and perineurium, causing separation of nerve fibers. Myelin sheaths of fibers showed an ondulation toward the axoplasm and the endoneurium. Separation of myelin layers from each other as a prominent feature of myelin degeneration in nerve fibers was also observed. Axoplasms exhibited edema and crystallization. CONCLUSIONS: The light microscopic and ultrastructural changes seen in peripheral nerves in experimental group operated with mesh suggested that mechanical compression of peripheral nerves is associated with myelin degeneration, endoneurinal and perineurial edema, fibrosis, axonal loss, and edema that may cause peripheral neuropathy. Chronic groin pain after hernia repair can be possibly caused by the entrapment of peripheral nerves in the scar tissue formed by the mesh.

Etiology and pathophysiology of primary and recurrent groin hernia formation.

The cause of primary groin hernia is multifactorial with evolutionary, hereditary, congenital, environmental aspects, and the general state of health all playing their part. Besides maintaining general body fitness and not smoking tobacco, there is little one can do to avoid this common affliction. On the other hand, recurrent groin hernia is largely due to easily controllable human factors and can be avoided by choosing an experienced surgeon with a particular interest and understanding of the subject, preferably one who specializes in and confines himself to the surgery of groin hernias, working in a unit dedicated to herniology he will select the best operation for the particular type of hernia and execute it to conform to the highest acceptable standards, using the best materials and techniques. The patient will rapidly, within a matter of days, return to his full, normal activities and can look forward to a success rate of over 99%.

[Value of the pubic tubercle as a CT reference point in groin hernias].

PURPOSE: To assess the value of the pubic tubercle as a CT reference point in diagnosing the different types of groin hernia before surgery in patients presenting with mechanical bowel obstruction. MATERIALS AND METHODS: Retrospective review of CT examinations performed for small bowel obstruction in our department during 2003. Twelve cases of groin hernia causing small bowel obstruction were included. All CT examinations were reviewed by 2 abdominal radiologists. The surgical report of all 12 included cases was reviewed for final diagnosis. RESULTS: Twelve cases of groin hernia causing small bowel obstruction were reviewed in our department during 2003. Eight cases corresponded to small bowel obstruction caused by inguinal hernia (4 direct and 4 indirect) and 4 to small bowel obstruction caused by femoral hernia. In each case, the diagnosis suggested at CT using the pubic tubercle as a reference point was surgically confirmed. CONCLUSION: The pubic tubercle is an excellent reference point at CT for diagnosing inguinal and femoral hernias. Preoperative diagnosis is important because it may change the choice of surgical procedure.

Myoma of the Round Ligament Causing Severe Groin and Thigh Pain

A 40-year-old woman experienced severe right groin and thigh pain. Her history included abdominal hysterectomy 6 years and exploratory laparotomy 2 years earlier. During the latter, left oophorectomy and appendectomy were performed, but did not eliminate the patient's groin pain. At laparoscopy we found a 20-mm myoma on the round ligament, which was excised. Three months postoperatively the woman had no groin pain and was in good health.

Collagen tampons as aminoglycoside carriers to reduce postoperative infection rate in prosthetic repair of groin hernias.

OBJECTIVE: To find out whether collagen tampons treated with gentamicin would prevent postoperative infections in patients operated on for groin hernias by insertion of prostheses. SETTING: University hospital, Italy. DESIGN: Prospective randomised trial. PATIENTS: 595 patients who required prosthetic repair of a groin hernia. INTERVENTIONS: All repairs were by our standard surgical technique including prophylactic ceftriaxone, local anaesthesia, and insertion of a polypropylene mesh. 301 patients also had a gentamicin laced collagen tampon placed in front of the prosthetic mesh before the aponeurosis of external oblique muscle was sutured. RESULTS: 1/301 patients in the gentamicin group (0.3%) developed a postoperative wound infection compared with 6/294 in the control group (2.0%), (p = 0.04 Fisher exact test). CONCLUSIONS: Gentamicin-laced collagen tampons are effective in reducing the postoperative infection rate in patients operated on for groin hernia by insertion of a prosthesis.

Recurrence and pain three years after groin hernia repair. Validation of postal questionnaire and selective physical examination as a method of follow-up.

OBJECTIVES: To evaluate recurrence rate and chronic groin pain three years after hernia repair and to validate a postal questionnaire with selective physical examination as a method of follow-up. DESIGN: Prospective cohort study. SETTING: County hospital, Sweden. PATIENTS: Prospective data were retrieved from the Swedish Hernia Register for patients aged 15-80 years at the time of groin hernia repair, operated on during 1994. INTERVENTIONS: Three years after operation patients were mailed a three-item questionnaire and invited to have a physical examination. Those examined answered a detailed questionnaire about pain and functional impairment. When appropriate an extended physical examination was undertaken to find out the probable cause of the pain. MAIN OUTCOME MEASURES: Recurrence, pain, and functional impairment. RESULTS: 272 hernias were repaired in 264 patients. 24 patients had died and 16 had a recurrence before the follow-up examination. After a median observation time of 44 months, 218 patients with 223 repairs (96%) were examined. Depending on the definition of recurrence and completeness of physical examination (selective or all patients) the recurrence rate varied between 10% (25/239) and 15% (35/239) including recurrences diagnosed before follow-up. 40 patients (18%) reported groin pain at follow-up, which was considered to be caused by a previous hernia repair in 34 (15%), 12 of whom (5%) had moderate or severe pain. Postoperative complications were associated with an increased risk of chronic pain, whereas type of hernia and use of mesh had no influence. CONCLUSIONS: The incidence of recurrence and chronic pain after hernia repair requires continuous audit in non-specialised units. Participation in a register and follow-up by a three-item questionnaire and selective physical examination provides a solid basis for quality control.
