Analysis and management of chronic testicular pain

A total of 45 patients was seen in consultation between May 1980 and April 1989 for chronic unilateral or bilateral orchialgia, defined as intermittent or constant testicular pain 3 months or longer in duration that significantly interferes with the daily activities of the patient so as to prompt him to seek medical attention. We analyzed 34 patients available for followup in terms of socioeconomic parameters, etiology and duration of pain, associated urological symptomatology, specific treatment and results of therapy. Of the patients 31 underwent surgical treatment after failing medical management (24 orchiectomies, 10 epididymectomies, 5 orchiopexies and 1 hydrocelectomy). Of 10 patients who underwent epididymectomy 9 underwent subsequent orchiectomy as definitive treatment. Of 15 patients who underwent inguinal orchiectomy 11 (73%) reported complete relief of pain, while 4 had partial relief. Of the 9 patients who underwent scrotal orchiectomy 5 (55%) reported complete relief of pain, 3 had partial relief and 1 denied improvement. On the basis of these results we recommend inguinal orchiectomy as the procedure of choice for the management of chronic testicular pain when conservative measures are unsuccessful.     

Continuous intrathecal morphine treatment for chronic pain of nonmalignant etiology: long-term benefits and efficacy

BACKGROUND: To analyze, prospectively, the long-term effects of continuous intrathecal morphine infusion therapy in 16 patients with chronic nonmalignant pain syndromes.METHODS: Twenty-five patients with severe, chronic, nonmalignant pain that had proven refractory to conservative management were considered candidates for trial of intrathecal spinal morphine. Sixteen patients achieved more than 50% pain relief after a trial period of intrathecal morphine infusion. They were implanted with fully implantable and programmable pumps through which morphine was delivered intrathecally on a continuous basis. These patients were followed prospectively and underwent careful evaluation of their functional and mental status, and pain intensity measurements using standardized techniques before treatment and every 6 months thereafter in the follow-up period. The follow-up period ranged from 13 months to 49 months (mean 29.14 months +/- 12.44 months) for the patients who had implanted morphine pumps.RESULTS: The mean morphine dosage initially administered was 1.11 mg/day (range 0.2--6.5 mg/day); after 6 months, it was 3.1 mg/day (range 0.4--8.75 mg/day). In long-term observation, no patient had a constant dosage history. The patients who received intrathecal morphine for longer than 2 years all showed an increase in morphine dosage to more than 10 mg/day. The best long-term results were seen with deafferentation pain and mixed pain, with 75% and 61% pain reduction (visual analog scale), respectively. Nociceptive pain patients had best pain relief initially (78% pain reduction) but it tended to decrease over the follow-up period to 57% pain reduction at final follow-up. The average pain reduction for all groups after 6 months was 67.5% and at last follow-up, it was 57.5%. Ten patients were satisfied with the delivery system and eleven reported improvement in their quality of life. In two patients, morphine was not able to adequately control the pain without producing undesirable side effects requiring the addition of clonidine to their infusion medication. In this series, 12 patients were considered successes and 4 patients were considered failures. In two patients, the intrathecal opioid therapy was unable to produce satisfactory pain relief and in the other two patients the pumps had to be explanted because of intolerable side effects.CONCLUSIONS: In our experience, the administration of intrathecal opioid medications for nonmalignant pain is justified in carefully selected patients.     

Laparoscopic adhesiolysis and relief of chronic pelvic pain.

OBJECTIVE: To evaluate the short- and long-term results of laparoscopic enterolysis in patients with chronic pelvic pain following hysterectomy. METHODS: Forty-eight patients were evaluated at time intervals from 2 weeks to 5 years after laparoscopic enterolysis. Patients were asked to rate postoperative relief of their pelvic pain as complete/near complete relief (80-100% pain relief), significant relief (50-80% pain relief), or less than 50% or no pain relief. RESULTS: We found that after 2 to 8 weeks, 39% of patients reported complete/near complete pain relief, 33% reported significant pain relief, and 28% reported less than 50% or no pain relief. Six months to one year postlaparoscopy, 49% of patients reported complete/near complete pain relief, 15% reported significant pain relief, and 36% reported less than 50% or no pain relief. Two to five years after laparoscopic enterolysis, 37% of patients reported complete/near complete pain relief, 30% reported significant pain relief, and 33% reported less than 50% or no pain relief. Some patients required between 1 and 3 subsequent laparoscopic adhesiolysis. A total of 3 enterotomies and 2 cystotomies occurred, all of which were repaired laparoscopically. CONCLUSION: We conclude that laparoscopic enterolysis may offer significant long-term relief of chronic pelvic pain in some patients.     

Endoscopic plantar fascia release

BACKGROUND: Endoscopic release of the plantar fascia is becoming an increasingly popular alternative to open procedures for the treatment of chronic plantar fasciitis. Although most patients can be successfully treated with Achilles tendon stretching, orthoses, physical therapy and corticosteroid injections, a small percentage of patients will have symptoms that are refractory to such treatments. METHODS: This is a retrospective review, analyzing the clinical outcome of 22 consecutive patients treated for chronic plantar fasciitis with endoscopic plantar fascia release by a single orthopaedic foot and ankle surgeon. RESULTS: These patients complained of symptoms for an average of 7.43 months before referral to the senior author (MS); 11 patients had chronic symptoms for 12 months or more. The ages at surgery ranged from 30 to 73 years. Followup averaged 8.48 (range 6 to 20) months. Satisfaction rate with this procedure was 97.7% and all patients reported at least a 50% improvement in pain after surgery. Twenty-two patients completed a modified Mayo Foot and Ankle Score: 15 of 22 (68%) were judged to have good or excellent results. Bilateral symptoms and prior ankle trauma or surgery were significantly correlated with less favorable results. CONCLUSIONS: Patients who had no previous foot trauma and had unilateral symptoms obtained the best results from this procedure. Even patients who had some residual pain in their foot were satisfied with the procedure and with the level of pain relief that had been achieved. Endoscopic plantar fascia release does appear to benefit selected patients who fail to respond to conservative therapy.     

Percutaneous dorsal column stimulator for chronic pain control

This is a retrospective review of 26 patients with chronic intractable pain in which dorsal column stimulation was used as a salvage procedure. On follow-up of 12 to 42.7 months, 21 of the patients had diminished narcotic usage. Seventeen patients subjectively rated their pain relief as good to excellent. Another five patients reported some relief of pain. Two-thirds of the patients reported an increase in their ability to perform daily activities such as walking, stair climbing, and time spent sitting. There are still many technical problems that plague this procedure, as evidenced by a very high technical complication rate of lead migration and lead breakage. Whether or not results diminish over long-term follow-up remains to be seen.     

Pain relief after cervical ganglionectomy (C2 and C3) for the treatment of medically intractable occipital neuralgia

Occipital neuralgia (ON) presents a diagnostic challenge because of the wide variety of symptoms, surgical findings, and postsurgical outcomes. Surgical removal of the second (C2) or third (C3) cervical sensory dorsal root ganglion is an option to treat ON. The goal of this study was to evaluate the short-term and the long-term efficacy of these procedures for management of cervical and occipital neuropathic pain. Twenty patients (mean age 48.7 years) were identified who had undergone C2 and/or C3 ganglionectomies for intractable occipital pain and a retrospective chart review undertaken. Patients were interviewed regarding pain relief, pain relief duration, functional status, medication usage and procedure satisfaction, preoperatively, immediately postoperative, and at follow-up (mean 42.5 months). C2, C3 and consecutive ganglionectomies at both levels were performed on 4, 5, and 11 patients, respectively. All patients reported preoperative pain relief following cervical nerve blocks. Average visual analog scale scores were 9.4 preoperatively and 2.6 immediately after procedure. Ninety-five percent of patients reported short-term pain relief (<3 months). In 13 patients (65%), pain returned after an average of 12 months (C2 ganglionectomy) and 8.4 months (C3 ganglionectomy). Long-term results were excellent, moderate and poor in 20, 40 and 40% of patients, respectively. Cervical ganglionectomy offers relief to a majority of patients, immediately after procedure, but the effect is short lived. Nerve blocks are helpful in predicting short-term success, but a positive block result does not necessarily predict long-term benefit and therefore cannot justify surgery by itself. However, since 60% of patients report excellent-moderate results, cervical ganglionectomy continues to have a role in the treatment of intractable ON.     

Linear accelerator radiosurgery using 90 gray for essential trigeminal neuralgia: results and dose volume histogram analysis

OBJECTIVE: To evaluate treatment of essential trigeminal neuralgia with 90 Gy delivered by a linear accelerator dedicated to radiosurgery. METHODS: This is a retrospective case series of 25 patients with essential trigeminal neuralgia treated from March 1999 to March 2001. All were treated with 90 Gy by means of a 5-mm collimator directed to the nerve root entry zone. Patient follow-up (range, 8-52 mo; median, 18 mo) was completed by an uninvolved party. Dose volume histograms of the brainstem were developed for the 20, 30, and 50% isodose lines by means of radiosurgery planning software. RESULTS: All patients obtained good to excellent pain relief with treatment. Nineteen (76%) of 25 patients achieved excellent pain relief (pain-free without medication). Six patients (24%) achieved good pain relief (50-90% reduction of pain with or without medication). Median time to pain relief was 2 months. Eight patients (32%) experienced relapse 4 to 13 months after treatment. Eight patients (32%) developed facial numbness, but none developed painful numbness. Mean brainstem volume within the 50% isodose line and occurrence of numbness was statistically significant (P = 0.03). There was no correlation between brainstem volume treated and outcome. CONCLUSION: Dedicated linear accelerator-based stereotactic radiosurgery that uses a 5-mm collimator to deliver 90 Gy to the nerve root entry zone is a safe and effective method for the treatment of essential trigeminal neuralgia. Care should be taken to limit brainstem volume included in the 50% isodose line in the treatment plan to avoid facial numbness.     

Gamma knife surgery for idiopathic trigeminal neuralgia performed using a far-anterior cisternal target and a high dose of radiation

OBJECT: Gamma knife surgery (GKS) has emerged as a suitable treatment of pharmacologically resistant idiopathic trigeminal neuralgia. The optimal radiation dose and target for this therapy, however, remain to be defined. The authors analyzed the results of GKS in which a high dose of radiation and a distal target was used, to determine the best parameters for this treatment. METHODS: The authors evaluated results in 47 patients who were treated with this approach. All patients underwent clinical and magnetic resonance imaging examinations at 6 weeks, 6 months, and 1 year post-GKS. Fifteen potential prognostic factors associated with favorable pain control were studied. The mean follow-up period was 16 months (range 6-42 months). The initial pain relief was excellent (100% pain control) in 32 patients, good (90-99% pain control) in seven patients, fair (50-89% pain control) in three patients, and poor (< 50% pain control) in five patients. The actuarial curve of pain relief displayed a 59% rate of excellent pain control and a 71% excellent or good pain control at 42 months after radiosurgery. Radiosurgery-induced facial numbness was bothersome for two patients and mild for 18 patients. Three prognostic factors were found to be statistically significant factors for successful pain relief: a shorter distance between the target and the brainstem, a higher radiation dose delivered to the brainstem, and the development of a facial sensory disturbance after radiosurgery. CONCLUSIONS: To optimize pain control and minimize complications of this therapy, we recommend that the nerve be targeted at a distance of 5 to 8 mm from the brainstem.

Augmentative treatment of chronic deafferentation pain syndromes after peripheral nerve lesions.

Deafferentation pain syndromes developing after peripheral nerve lesions are difficult to treat. According to the follow-up (mean: 39.5 months) of 6 patients suffering from causalgic pain we will present our method of augmentative therapy in chronic neuropathic pain caused by peripheral nerve lesions, i.e., peripheral nerve stimulation (PNS), spinal cord stimulation (SCS) and chronic intrathecal opioid infusion. None of the patients showed intraoperative or follow-up complications. Evaluated by visual analogue scales all patients reported a good to excellent pain relief (75-100%). (1) Regarding the favourable long-term results of PNS, this method should be considered in cases of mononeuropathic pain syndromes. (2) Neuropathic pain syndromes which are not assignable to a singular nerve lesion, can often be managed effectively by SCS. (3) In contrast to the widespread opinion, deafferentation pain syndromes of central or peripheral origin can be treated satisfactorily by intrathecal opiate administration.

Diagnosis and laparoscopic repair of type I obturator hernia in women with chronic neuralgic pain.

BACKGROUND: We performed a pilot study review of 7 female patients suffering with obturator neuralgia produced by a type I obturator hernia. Diagnosis and laparoscopic treatment of this rare hernia are presented. METHODS: Patients with chronic pelvic pain and signs of obturator neuralgia were identified retrospectively by chart review. These patients had been referred to our chronic pelvic pain clinic. Outcomes of their surgery from February through November 2001 were analyzed. Median length of follow-up was 11 months (range, 6 to 16). A new technique using Cooper's ligament and arcus tendineus fasciae pelvis was used for the tension-free mesh hernia repair. RESULTS: In this pilot study, 6 of 7 patients (86%) received greater than 50% relief of their chronic pelvic pain, which leads to the conclusion that we have at least 95% confidence that the pain reduction achieved is greater that 50%. Due to the small sample size, no statistically meaningful conclusions could be reached. All of the patients have reported some pain relief and increased function since surgery. CONCLUSION: Symptomatic type I obturator hernias may be more common than previously thought. Patients with obturator neuralgia, persisting longer than 6 months despite conservative therapy, may respond to laparoscopic reduction of the pilot fat tag and mesh overlay of the obturator canal.     

Percutaneous vertebroplasty for pain relief and spinal stabilization

STUDY DESIGN: This was a retrospective review of 47 consecutive patients (1995-1998) in whom percutaneous intraosseous methylmethacrylate cement injection (percutaneous vertebroplasty) was used to treat osteoporotic vertebral compression fractures and spinal column neoplasms. OBJECTIVES: To present initial results regarding pain relief, spinal stabilization, and complications after treatment with percutaneous vertebroplasty. SUMMARY OF BACKGROUND DATA: Percutaneous vertebroplasty was developed in France in the late 1980s. Several European reports have described excellent results for treatment of compression fractures and neoplasms. The procedure was not performed in the United States until 1994. Only a single series of 29 patients treated in the United States has been reported. METHODS: A retrospective review was conducted of 47 consecutive patients with 84 vertebrae treated with percutaneous vertebroplasty. Thirty-eight patients with 70 vertebrae had symptomatic, osteoporotic fractures and had failed medical therapy. Eight patients with 13 vertebrae had primary or metastatic neoplasms. One patient had a hemangioma. Immediate and long-term pain response, spinal stability, and complications were evaluated. RESULTS: Among the 38 patients treated for osteoporotic fractures, 24 (63%) had marked to complete pain relief, 12 (32%) moderate relief and 2 (5%) no significant change. Only 4 of the 8 patients with malignancies had significant pain relief. In 7 of these patients, no further vertebral compression occurred, and spinal canal compromise was prevented. The patient with the hemangioma had no significant pain reduction. Minor complications occurred in 3 (6%) patients. CONCLUSIONS: Percutaneous vertebroplasty provided significant pain relief in a high percentage of patients with osteoporotic fractures. The procedure provided spinal stabilization in patients with malignancies but did not produce consistent pain relief. Complications were minor and infrequent. Percutaneous vertebroplasty is a promising therapy for patients with osteoporotic fractures and for selected vertebral column neoplasms.     

Clinical Outcomes After Extracorporeal Shock Wave Therapy for Chronic Plantar Fasciitis in a Predominantly Active Duty Population

Chronic plantar fasciitis is a common cause of foot pain, with conservative treatment providing relief for most patients. However, because of the common occurrence of this pathology, this leaves many patients dissatisfied. The purpose of the present study was to determine the effectiveness of extracorporeal shock wave therapy (ESWT) to treat chronic plantar fasciitis (PF) in a largely active duty population. A review of 82 patients (115 heels) who had undergone ESWT for chronic PF was performed. Outcome data were obtained by patient telephone interviews. All ESWT was conducted at 24 kV for 2000 shocks. Of the 82 patients (115 heels), 76 (93%; 111 heels) agreed to participate. Their mean age was 42?±?10 years, with 41 males (54%) and 35 females (46%). The mean follow-up period was 42?±?22 months. Of the patients, 73.6% were active duty military personnel. The mean preoperative pain score of 7.8?±?2 had improved to 2.5?±?2 at the last follow-up visit (p?<.0001). Active duty patients reported a mean improvement in pain of 4.8?±?3 compared with 6.8?±?3 in non-active duty patients (p?=?.005). Of the 76 patients, 75 (98%) underwent 1 ESWT session, and 1 (2%) requiring 2 sessions. Overall, 74% of patients rated the outcome of their procedure as either good or excellent, with 87% stating that ESWT was successful. Ten patients (18%) left the military because of continued foot pain, with 76% able to return to running. For patients with chronic PF, these results support the use of ESWT to relieve pain in >85% of patients, with a preponderance for better pain relief in patients who are not active duty military personnel.     

Bilateral chronic proximal plantar fasciopathy: treatment with electrohydraulic orthotripsy

BACKGROUND: Patients presenting for treatment of chronic plantar fasciopathy often have bilateral involvement. When various nonoperative treatments fail, subsequent intervention may be problematic, especially since bilateral surgery (bilateral fascial release) may not be realistic because of variable, frequently restrictive postoperative weightbearing limitations. METHODS: Twenty-three patients (46 heels) were treated with electrohydraulic high-energy orthotripsy to the plantar entheses of both feet while under the same anesthesia (conscious sedation). Following orthotripsy, all patients immediately were fully weightbearing and resumed normal activities of daily living and work, usually within 24 hours. Progressive return to athletic activities was allowed. Patients were assessed by three outcome parameters: (1) pain measured objectively by a dolorimeter combined with the patient's subjective evaluation of the level of pain; (2) pain after 5 minutes of walking upon arising; and (3) pain with daily activities. All pain measurements were done by the visual analog scale. RESULTS: Patients initially experienced varied pain relief responses. This included earlier pain relief in one heel compared to the other, as well as better pain relief in one heel than the other at the 6- and 12-week evaluations, but with much less variance at the 1-year evaluation. By 3 months following orthotripsy, 28 heels (61%) had good or excellent results. These results were maintained or improved at 1 year. In 18 heels (39%), the outcome was fair or poor. Nineteen heels received a second orthotripsy application; one patient requested a second orthotripsy treatment of only one heel, while nine patients requested a second treatment of both heels. The outcome showed further improvement following the second application of orthotripsy. At 1 year after one or two orthotripsy applications, 19 patients (38 heels) were satisfied with the results in both heels (83%), while four patients (eight heels) still had an unsatisfactory outcome (17%). CONCLUSION: Electrohydraulic high-energy orthotripsy is a reasonable nonincisional method for treating patients with bilateral chronic proximal plantar fasciopathy under a single anesthetic without the prolonged nonweightbearing status often recommended for patients following unilateral open or endoscopic fascial release.     

Patient attitudes regarding pca and associated costs

Purpose

To determine patients’ knowledge and attitudes towards patient-controlled analgesia (PCA) costs through the use of our acute pain service quality assurance (QA) programme.

Methods

Quality Assurance questionnaires were distributed to all patients receiving PCA opioids for > 12 hr. Patients were asked to note the presence of side effects (nausea/vomiting, pruritus, urinary retention), to indicate their satisfaction with regard to their pain relief, follow-up assessments, treatment of side effects, and to recall the previous method of pain relief and their satisfaction with it. Patients were also asked to estimate the total cost of PCA (0-$50. $50–100, $100–200, > $200), and what amount if any they would be willing to pay (0–$50. $50–100, $ 100–200. > $200). Results obtained over a recent four month period were reviewed.

Results

One hundred and thirty-three questionnaires were distributed and 103 (77%) were returned. The percentage of patients rating their satisfaction as very good or excellent was 86% for pain relief. 96% for follow-up. 71 % for side effect treatment, but only 43% for their previous surgical pain relief (P < 0.001). The distribution of cost estimates was 10% $50–100, 37% $100–200 and 53% > $200 with 60% willing to pay a portion of this cost. Those willing to pay were more likely to have had very good or excellent pain relief (94% vs 71%.P < 0.05) and treatment of side effects (71 %vs 48%.P < 0.05) than those not willing to pay.

Conclusions

Patients continue to be highly satisfied with PCA therapy and are aware of the costs involved. A majority of patients were willing to pay to obtain this service if necessary. Patients who had poorer pain relief and less efficacious treatment of their side effects were less willing to pay.     

Shock-wave therapy is effective for chronic calcifying tendinitis of the shoulder.

We report a prospective study of the effects of extracorporeal shock-wave therapy in 195 patients with chronic calcifying tendinitis. In part A 80 patients with chronic symptoms were randomly assigned to a control and three subgroups which had different treatment by low-energy and high-energy shock waves. In part B 115 patients had either one or two high-energy sessions. We recorded subjective, functional and radiological findings at six months after treatment. The results showed energy-dependent success, with relief of pain ranging from 5% in our control group up to 58% after two high-energy sessions. The Constant scores and the radiological disintegration of calcification were also dose-dependent. Shockwave therapy should be considered for chronic pain due to calcific tendinitis which is resistant to conservative treatment.
