The role of ultrasound-guided cytology of groin lymph nodes in the management of squamous cell carcinoma of the vulva: 5-year experience in 44 patients.

AIM: To assess the accuracy of ultrasound combined with fine-needle aspiration cytology (FNAC) in the detection of lymph node metastasis in patients with squamous cell carcinoma of the vulva. MATERIALS AND METHODS: The groin nodes of 44 consecutive patients with primary squamous cell carcinoma of the vulva undergoing groin node dissection were assessed with ultrasound and FNAC. The results were compared with histology from subsequent inguinofemoral lymph node dissection. Twenty-nine patients underwent bilateral groin node dissections and 15 unilateral providing comparable data for 73 groins. RESULTS: Histology demonstrated metastatic disease in 28 groins and no evidence of metastatic disease in 45. Ultrasound agreed with the histology in 67 of the 73 groins (92%), with two false-positives, four false-negatives and two indeterminate appearances. Cytology agreed with the histology in 65 of 72 FNAC samples obtained (90%), with six false-negatives, and one indeterminate result. No false-positive cytology results were seen. Ultrasound and FNAC together failed to detect metastatic disease in four groins, one with an indeterminate ultrasound appearance, another with indeterminate cytology, the two others each having a single positive inguinal node despite a negative ultrasound and FNAC. CONCLUSION: The combination of ultrasound and FNAC provides a sensitive and specific tool for pre-operative assessment and may prevent unnecessary groin dissection and the attendant morbidity in selected patients with vulval cancer.

Hip joint range of motion reduction in sports-related chronic groin injury diagnosed as pubic bone stress injury.

Traumatic osteitis pubis is a non-specific entity that relates to chronic groin injury and has recently been described as being akin to a pubic bone stress injury. It is uncertain whether or not reduction of hip joint range of motion occurs in traumatic osteitis pubis. The purpose of this study was to establish whether there is a reduction of hip range of motion in athletes who have chronic groin injury diagnosed as pubic bone stress injury. A case-control study was performed whereby 89 Australian Rules footballers underwent, with clinical history unknown, clinical and MRI examination of the groin region. Clinical criteria (pain with tenderness) and MR-criteria (pubic bone marrow oedema) were used for diagnosis of pubic bone stress injury. End-range internal and external rotation hip motion was measured using a goniometer. Athletes with and without symptoms were compared, as were athletes with current symptoms with athletes who had recovered from their groin pain episode. Chronic groin injury was diagnosed in 47 athletes with 37 having pubic bone stress injury. Thirteen athletes had previous groin injury. A reduction of internal and external hip range of motion was demonstrated in athletes with pubic bone stress injury (p < 0.05) and in athletes who had current symptoms compared to those who had recovered from their groin pain episode (p < 0.05). A reduction in hip range of motion was evident in athletes with chronic groin injury diagnosed as pubic bone stress injury. There may be a role for increasing hip range of motion in rehabilitation.

Combined ischemic preconditioning and laser Doppler measurement for early division of pedicled groin flap.

OBJECTIVES: The main disadvantage of the pedicled groin flap for hand reconstruction is the long period of immobilization required. Early division of the pedicled groin flap is desirable for both patients and surgeons. The aims of this study were to investigate whether ischemic preconditioning can effectively accelerate the neovascularization of the junction between the donor and recipient sites in the pedicled flap, and the most objective method of judging the timing of early division of the pedicled groin flap. This report is the first prospective study to use ischemic preconditioning for early division of pedicled cutaneous flap combined with laser Doppler measurement. METHODS: The severe hand injuries of 12 patients were reconstructed by using the pedicled groin flap method. The ischemic preconditioning program was prospectively performed as scheduled for 5 to 7 days postoperatively. The pedicled groin flap was monitored with laser Doppler when the flap was elevated, inset, with clamping and nonclamping postoperatively. RESULTS: Eleven of the 12 pedicled groin flaps were divided safely and survived completely. Only one pedicled groin flap with a simultaneous harvest of iliac bone graft had partial flap loss, giving a success rate of 90.1%. CONCLUSION: With ischemic preconditioning, the pedicled groin flap can be safely divided postoperatively at a mean period of 8.4 days according to the laser Doppler measurement, especially when the perfusion unit ratio of clamping over nonclamping reaches more than 36.6%.

Radiation therapy versus pelvic node resection for carcinoma of the vulva with positive groin nodes.

From 1977 to 1984, 114 eligible patients with invasive squamous cell carcinoma of the vulva and positive groin nodes after radical vulvectomy and bilateral groin lymphadenectomy were randomized to receive either radiation therapy or pelvic node resection. Fifty-three of the 59 patients randomized to radiation therapy received a 4500- to 5000-rad tumor dose in five to 6.5 weeks bilaterally to the groins and to the midplane of the pelvis even if only unilateral positive groin nodes had been detected; no radiation was given to the central vulvar area. Fifty-three of the 55 patients randomized to further surgery had pelvic node resection performed on the side containing positive groin nodes either unilaterally or bilaterally. Acute and chronic morbidity was similar for both regimens. The two major poor prognostic factors were clinically suspicious or fixed ulcerated groin nodes and two or more positive groin nodes. The difference in survival for the 114 evaluable patients was significant, favoring the adjunctive radiation therapy group (P = .03). The estimated two-year survival rates were 68% for the radiation therapy group and 54% for pelvic node resection group. The most dramatic survival advantage for radiation therapy was in patients who had either of the two major poor prognostic factors present; at this time, the benefit of radiation therapy for the remaining patients is uncertain. In this randomized prospective study, the addition of adjunctive groin and pelvic irradiation therapy after radical vulvectomy and inguinal lymphadenectomy proved superior to pelvic node resection.

Groin recurrence after micrometastasis in a sentinel lymph node in a patient with vulvar cancer.

BACKGROUND: The sentinel lymph node concept is attractive in vulvar cancer because of the potential to avoid the morbidity associated with formal groin dissection. CASE: An 84-year-old patient with a T2 carcinoma of the anterior vulva underwent surgery including bilateral sentinel node excision after identification with technetium-labeled nanocolloid. Frozen section histology showed a tumor deposit <1 mm in diameter in a left groin node whereas four nodes in the right groin were apparently negative. Completion lymphadenectomy was performed only for the left groin. Final histology including serial sectioning showed a micrometastasis in one of seven nodes from the right groin; no further treatment was given. Sixteen months postoperatively the patient developed a recurrence in the right groin; the left groin was free of tumor. CONCLUSION: This case indicates that groins with a micrometastasis detected by sentinel lymph node excision require further treatment.

Groin dissection in the treatment of lower-extremity melanoma. Short-term and long-term morbidity.

Groin dissection was performed in 151 consecutive patients from 1970 to 1984. Groin dissections were therapeutic in 138 cases (91%) and elective in 13 (9%). One hundred forty-three patients (95%) underwent an ilioinguinal node dissection, while eight (5%) were treated with an inguinal node dissection. In 88 patients, the groin dissection was combined with isolated regional perfusion. Primary wound closure was performed in 140 patients (93%). There was no 30-day postoperative mortality. Complications included temporary seroma (26 [17%] of 151 patients), wound infection (14 patients [9%]), wound necrosis (five patients [3%]), and edema (30 patients [20%]). Residual inguinal node metastases after groin dissection did not occur. Morbidity of groin dissection did not increase when the groin dissection was combined with isolated regional perfusion. Quantification of the degree of edema in 66 patients revealed functional limitation due to edema in three patients (4.5%). This technique of groin dissection gives good results with minimal functional morbidity of the affected leg.

Five-year follow-up of a randomized trial to assess pain and numbness after laparoscopic or open repair of groin hernia.

BACKGROUND: Claims that laparoscopic groin hernia repair is followed by less persisting pain and numbness than open mesh repair were tested by follow-up within a multicentre randomized clinical trial. METHODS: Participants in the UK Medical Research Council Laparoscopic Groin Hernia Trial were followed up by means of self-completed postal questionnaires from 2 to 5 years after trial entry. The principal measures were pain (groin and testicular) and numbness (groin and thigh). RESULTS: Seven hundred and fifty (80.8 per cent) of the original 928 participants returned at least one questionnaire between 2 and 5 years; respondents were similar to the baseline randomized groups. Fewer respondents in the laparoscopic group had groin pain (absolute differences varied between 7.9 and 2.0 per cent, but were of marginal statistical significance); rates of testicular pain were similar in the two groups. Groin numbness was reported about half as commonly at all time points in the laparoscopic group (P < 0.001); there were no significant differences in thigh numbness. CONCLUSION: Laparoscopic surgery was associated with less long-term numbness and probably less pain in the groin.

The effectiveness of complete decongestive physiotherapy for the treatment of lymphedema following groin dissection for melanoma.

OBJECTIVE: Groin dissection is performed for the treatment of melanoma and other malignancies. Lymphedema rates as high as 47% have been reported. In 1996, we began using complete decongestive physiotherapy (CDP) in selected patients with lymphedema following groin dissection. Here, we review our results in a small cohort of patients. METHODS: A retrospective review of the medical records of 14 patients, treated with CDP for lymphedema secondary to groin dissection for melanoma was conducted. All patients were treated with CDP at Roswell Park Cancer Institute (RPCI), between 1996 and 2002. Of the 14 patients, 12 underwent groin dissection at RPCI. Response to therapy was measured by limb volume determinations. Patient gender, age, body mass index (BMI), type of operation, type of adjuvant therapy, time to treatment, patient compliance, lymphedema stage, and initial edema were analyzed for association with response to treatment. Incidence was estimated by a review of the operative logs. RESULTS: Fourteen patients were treated with CDP for lymphedema secondary to groin dissection for melanoma, with a median decrease in lymphedema of 60% (range: 35-145%; P = 0.0003). Increased BMI was associated with a decreased response to treatment (P = 0.02). Response to CDP was not effected by time to treatment, patient compliance, lymphedema stage, and initial edema. During this time, 39 groin dissections were done at RPCI. The incidence of lymphedema treated with CDP at RPCI was 31% (12/39; standard error 7.4%). CONCLUSIONS: With a decrease in lymphedema of 60%, CDP may provide relief for patients with lymphedema following groin dissection. Elevated BMI was associated with a decreased response to CDP.

Prevalence and severity of chronic groin pain after endoscopic totally extraperitoneal inguinal hernioplasty.

BACKGROUND: Chronic groin pain after open inguinal hernia repair is a common long-term morbidity, but its incidence after endoscopic totally extraperitoneal inguinal hernioplasty (TEP) has not been studied in detail. The objective of this study was to evaluate the prevalence and severity of chronic groin pain after TEP. METHODS: Between June 1999 and September 2001, 313 consecutive patients who underwent TEP at our institution were recruited. To evaluate the incidence and severity of chronic pain, a cross-sectional telephone survey using a standardized questionnaire was conducted by a research assistant. Clinical data between the chronic pain group and the pain-free group were compared to identify any clinical factors that had a significant association with the subsequent development of chronic groin pain. RESULTS: The prevalence of chronic groin pain was 9.2% ( n = 24). The severity of the pain was mild ( n = 18), moderate ( n = 5), or severe ( n = 1). In more than half of the patients, the groin pain occurred less often than once a month and its duration did not exceed 1 min. Only one patient reported an impairment of functional activities as a result of the pain. Multivariate analyses identified a significant association between a high postoperative pain score on coughing on postoperative day 6 and the subsequent development of groin pain. CONCLUSIONS: The prevalence of chronic groin pain in patients after TEP was low. The pain was mostly mild and transient without associated sensory symptoms. The occurrence of pain had a negligible impact on daily activities.

Effectiveness of active physical training as treatment for long-standing adductor-related groin pain in athletes: randomised trial.

BACKGROUND: Groin pain is common among athletes. A major cause of long-standing problems is adductor-related groin pain. The purpose of this randomised clinical trial was to compare an active training programme (AT) with a physiotherapy treatment without active training (PT) in the treatment of adductor-related groin pain in athletes. METHODS: 68 athletes with long-standing (median 40 weeks) adductor-related groin pain--after examination according to a standardised protocol--were randomly assigned to AT or PT. The treatment period was 8-12 weeks. 4 months after the end of treatment a standardised examination was done. The examining physician was unaware of the treatment allocation. The ultimate outcome measure was full return to sports at the same level without groin pain. Analyses were by intention to treat. FINDINGS: 23 patients in the AT group and four in the PT group returned to sports without groin pain (odds ratio, multiple-logistic-regression analysis, 12.7 [95% CI 3.4-47.2]). The subjective global assessments of the effect of the treatments showed a significant (p=0.006) linear trend towards a better effect in the AT group. A per-protocol analysis did not show appreciably different results. INTERPRETATION: AT with a programme aimed at improving strength and coordination of the muscles acting on the pelvis, in particular the adductor muscles, is very effective in the treatment of athletes with long-standing adductor-related groin pain. The potential preventive value of a short programme based upon the principles of AT should be assessed in future, randomised, clinical trials.

Comparison of reliability between the modified groin flap and the forearm flap in oral reconstruction.

OBJECTIVE: The groin flap has the advantage of minimum donor-site morbidity, while having the disadvantage of short vascular pedicle of small caliber. Modification of the groin flap has improved the former disadvantage, but the latter one remains. The purpose of this study was to compare the reliability of the modified groin flap with the forearm flap. STUDY DESIGN: Eleven modified groin flaps and 40 forearm flaps consecutively performed by a single surgeon in a hospital for patients with oral cancer were retrospectively reviewed. RESULTS: The rate of total flap loss in the modified groin flap group (8.3%) was higher than that in the forearm flap group (2.5%). The rates of partial flap loss in both flaps were similar to those of total flap loss. The failures of the modified groin flap and the forearm flap were due to arterial and venous complications, respectively. CONCLUSION: The modified groin flap appears to be a little less reliable than is forearm flap; nevertheless, it could be a good option for patients who desire less conspicuous postoperative scars.

Groin flap design and versatility.

The groin flap is a reliable and well-established reconstructive option for pedicled or free-tissue transfer. Concern regarding its variable vascular origin and caliber has limited its use. To overcome this, a simplified guideline based on the transverse diameter of the patient's index and long fingers at the distal interphalangeal level has been developed. Thus "rule of two finger widths" positions the origin of the vascular pedicle from the femoral vessels two finger widths below the inguinal ligament, the upper flap border two finger widths above the inguinal ligament, the lower flap border two finger widths below the vascular origin, and both parallel to the flap axis, which lies along a line from the vascular origin to the anterosuperior iliac spine. This new groin flap design provides the necessary guidelines for vascular identification, accommodates pediatric and adult stature, and ensures primary donor-site closure if flap dimensions are within the prescribed boundaries. In addition, a new sartorius-cutaneous groin flap is presented. This combines the cutaneous groin flap with the proximal sartorius muscle (up to 15 cm), which is supplied by the deep vessels of the superficial circumflex iliac system. The sartorius-cutaneous groin flap further emphasizes the concept of single-pedicle compound or combined flaps and additionally enhances the extensive reconstructive versatility of previously described groin flaps. Over 200 pedicled and free groin flaps have been performed according to the "rule of two finger widths" over the past 5 years. There have been no complications related to flap design, such as difficulty with flap elevation, marginal necrosis, or donor-site closure.(ABSTRACT TRUNCATED AT 250 WORDS)

Description of pain provocation tests used for the diagnosis of sports-related chronic groin pain: relationship of tests to defined clinical (pain and tenderness) and MRI (pubic bone marrow oedema) criteria.

The clinical assessment of groin pain in athletes is difficult, with the lack of specific clinical tests being in part responsible. Three pain provocation tests used in the diagnosis of chronic groin pain are described and their relationship to defined clinical and MRI criteria has been assessed. Eighty-nine Australian Rules football players with and without groin symptoms underwent clinical examination followed by history. Three pain provocation tests were performed (named as the Single Adductor, Squeeze and Bilateral Adductor tests). All athletes subsequently underwent MRI of their groin region for the presence of significant pubic bone marrow oedema (BMO). Of the 89, 47 were defined as having chronic groin pain, and 46 had significant BMO with 37 having both chronic groin pain and BMO. The three pain provocation tests demonstrated only moderate sensitivity (range 30-65%). Positive predictive values were moderate to high (67-93%) depending upon the individual test. The Bilateral Adductor test was the most sensitive test with the highest positive predictive values. The high specificity (88-93%) demonstrated should be treated with caution due to the study methodology. Three pain provocation tests of potential value in assessing chronic groin pain in athletes are described. If positive, all three pain provocation tests demonstrated a high likelihood for the athlete having MR-detected parasymphyseal pubic BMO. Further research is required on assessing the clinical usefulness of these tests.

Concurrent analysis of nose and groin swab specimens by the IDI-MRSA PCR assay is comparable to analysis by individual-specimen PCR and routine culture assays for detection of colonization by methicillin-resistant Staphylococcus aureus.

The IDI-MRSA assay (Infectio Diagnostic, Inc., Sainte-Foy, Quebec, Canada) with the Smart Cycler II rapid DNA amplification system (Cepheid, Sunnyvale, CA) appears to be sensitive and specific for the rapid detection of nasal colonization by methicillin-resistant Staphylococcus aureus (MRSA). We assessed the sensitivity and specificity of this assay under conditions in which both the nose and cutaneous groin specimens were analyzed together and compared the accuracy of this PCR approach to that when these specimens were tested separately and by culture assays in an inpatient population with known high rates (12 to 15%) of MRSA colonization. Of 211 patients screened, 192 had results assessable by all three methods (agar-broth culture, separate nose and groin IDI-MRSA assay, and combined nose-groin IDI-MRSA assay), with MRSA carriage noted in 31/192 (16.1%), 41/192 (21.4%), and 36/192 (18.8%) patients by each method, respectively. Compared to agar culture results, the sensitivity and specificity of the combined nose-groin IDI-MRSA assay were 88.0% and 91.6%, respectively, whereas when each specimen was processed separately, the sensitivities were 90.0% (nose) and 83.3% (groin) and the specificities were 91.7% (nose) and 90.2% (groin). IDI-MRSA assay of a combined nose-groin specimen appears to have an accuracy similar to that of the current recommended PCR protocol, providing results in a clinically useful time frame, and may represent a more cost-effective approach to using this assay for screening for MRSA colonization.

Groin pain associated with ultrasound finding of inguinal canal posterior wall deficiency in Australian Rules footballers.

OBJECTIVES: To investigate the prevalence of inguinal canal posterior wall deficiency (sports hernia) in professional Australian Rules footballers using an ultrasound technique and correlate the results with the clinical symptom of groin pain. METHODS: Thirty five professional Australian footballers with and without groin pain were investigated blind with a dynamic high resolution ultrasound technique for presence of posterior wall deficiency. RESULTS: Fourteen players had a history of significant recent groin pain and ten of these were found to have bilateral inguinal canal posterior wall deficiency (p < 0.01). The relative risk for a history of groin pain with bilateral deficiency was 8.0 (95% confidence interval 1.73 to 37.1). Groin pain was also found to be associated with increasing age (p < 0.01) which was an independent risk factor. Surgical, clinical, and ultrasound follow up for players who underwent hernia repair confirmed the validity of ultrasound as a diagnostic tool. CONCLUSIONS: Dynamic ultrasound examination is able to detect inguinal canal posterior wall deficiency in young males with no clinical signs of hernia. This condition is very prevalent in professional Australian Rules footballers, including some who are asymptomatic. There was a correlation between bilateral deficiency and groin pain, although the temporal relationship between the clinical and ultrasound findings is not established by the current study. Ultrasound shows promise as a diagnostic tool in athletes with chronic groin pain who are considered possible candidates for hernia repair.

Endoscopic evaluation and treatment of groin pain in the athlete.

BACKGROUND: Chronic groin pain in athletes forms a major diagnostic and therapeutic challenge. HYPOTHESIS: Evaluate and treat undiagnosed groin pain in the athlete by endoscopy. STUDY DESIGN: Prospective cohort study. METHODS: Athletes who were referred to the Ikazia Hospital with undiagnosed chronic groin pain between January 1998 and August 2001 were included. Radiography, bone scintigraphy, and ultrasonography were performed. In 14 athletes, groin pain remained undiagnosed. Ten patients complained of unilateral, 4 of bilateral groin pain. Patients underwent a transabdominal or extraperitoneal diagnostic endoscopy. RESULTS: All patients were operated ambulatory without significant difficulties. Pathology found by endoscopy was hernia inguinalis (n = 9), hernia femoralis (n = 4), preperitoneal lipoma (n = 3), and hernia obturatoria (n = 1). Only once was there no pathology. In 17 groins, a Prolene mesh was placed preperitoneally. Thirteen patients (93%) returned to full activity within 3 months of surgery. One year after surgery, one patient had minor symptoms and one patient had persistent symptoms. All other patients had no complaints. CONCLUSIONS: An occult hernia should be high on the list of differential diagnoses in undiagnosed chronic groin pain in athletes. Operative treatment can return the patient to his sport within 3 months.

Delayed onset of transversus abdominus in long-standing groin pain.

UNLABELLED: Long-standing groin pain is a persistent problem that is commonly difficult to rehabilitate. Theoretical rationale indicates a relationship between the motor control of the pelvis and long-standing groin pain; however, this link has not been investigated. PURPOSE: The current experiment aimed to evaluate motor control of the abdominal muscles in a group of Australian football players with and without long-standing groin pain. METHODS: Ten participants with long-standing groin pain and 12 asymptomatic controls were recruited for the study. Participants were elite or subelite Australian football players. Fine-wire and surface electromyography electrodes were used to record the activity of the selected abdominal and leg muscles during a visual choice reaction-time task (active straight leg raising). RESULTS: When the asymptomatic controls completed the active straight leg raise (ASLR) task, the transversus abdominus contracted in a feed-forward manner. However, when individuals with long-standing groin pain completed the ASLR task, the onset of transversus abdominus was delayed (P < 0.05) compared with the control group. There were no differences between groups for the onset of activity of internal oblique, external oblique, and rectus abdominus (all P > 0.05). CONCLUSIONS: The finding that the onset of transversus abdominus is delayed in individuals with long-standing groin pain is important, as it demonstrates an association between long-standing groin pain and transversus abdominus activation.

[The groin pain syndrome].

Groin pain is defined as tendon enthesitis of adductor longus muscle and/or abdominal muscles that may lead to degenerative arthropathy of pubic symphises in an advanced stage. Pubic region is a point where kinematic forces cross. The balance between the adductor and abdominal muscles is of great importance, as well as the elasticity of pubic symphises which enables movement of up to 2 mm and rotation of up to 3 degrees. The weakness of the abdominal muscle wall, known as the sportsman's hernia, is the most common cause of painful groin. Groin pain is the most common in soccer players (6.24% in Croatia). Most authors believe that the main cause of groin pain is the adductor muscle overload. When active, sportsmen start to feel a dull pain in the groin region. The adductor test is of great importance for physical examination; the patient should be lying supine with his hips abducted and flexed at 80 degrees. The test is positive if the patient, while attempting to pull his/her legs against pressing in the opposite direction, feels a sharp pain in the groins. The treatment of groin pain is complex and individual, as its causes may vary from patient to patient. Gradual physical therapy combined with pharmacotherapy should be effective in most cases. The latter includes nonsteroid anti-inflammatory drugs and muscle relaxants. A physical therapy programme usually involves stretching and strengthening of adductor muscles, abdominal wall muscles, iliopsoas muscle, quadriceps, and hamstrings. In case that physical therapy and pharmacotherapy fail, surgery is needed, depending on the cause.
