Toe-to-Hand Transfer in an Ulnar Hemimelia Patient: A Case Report.

Ulnar hemimelia is a rare congenital deformity. The severity of the deformity increases with the number of fingers that are absent. Clearly, grip function is impossible with a mono-finger hand. Here, we present a case report of a patient with bilateral ulnar hemimelia that included the absence of radial fingers and also deformity in the toes of his left foot. A toe-to-hand transfer was performed successfully to help the patient gain grip function. Both the patient and the parents were very pleased with the result. To our knowledge, this is the first case report of a patient with ulnar hemimelia and absent radial fingers who was treated with a toe-to-hand transfer.The most important factors in a successful surgery are careful preoperative planning and microsurgical expertise. Angiography is the key to careful planning, and physiotherapy should also be done to increase the patient's functions. The psychological well-being of patients and parents will be positively affected after a successful surgery.

The success of salvage procedures for failing digital replants: A retrospective cohort study.

BACKGROUND: The success of salvage procedures for failing digital replants (FR) is poorly documented. We sought to evaluate the success of salvage procedures for FR and factors contributing to successes and failures of replants. METHODS: Adult patients who presented to our center between January 1, 2000 and December 31, 2015, suffered ≥1 digital amputation(s), and underwent digital replantation were included. Preoperative, perioperative, and postoperative details were recorded. Digits were monitored postoperatively via nursing and physician assessments. The presumed reason for failure, details, and outcomes of salvage attempts were recorded for FR. Length of hospital stay and complications were also recorded. RESULTS: Fifty-two patients and 83 digits were included. Fifty-two digits (63%) were compromised (arterial ischemia in 15 digits; venous congestion in 37 digits) and 48 digits had salvage therapy. Twenty-one FR (44%) were salvaged via operative (1 of 2; 50%), nonoperative (19 of 43; 44%), and combined (1 of 3; 33%) therapies. FR patients were more likely than those with successful replants to receive a blood transfusion (52 vs. 23%; p = .009) with more transfused units (3.45 ± 3.30 vs. 0.86 ± 0.95; p = .001). Length of stay was prolonged for FR patients (9 [range: 2-22] vs. 7 [range: 3-19] days; p = .039). Ultimately, 59% (49 of 83) of replants were successful, where 25% (21 of 83) were successfully salvaged. CONCLUSION: Nonoperative and operative salvage therapies improve the rate of replant survival. We suggest close postoperative monitoring of all replants and active salvage interventions for compromised replants in the postoperative period.

Early Ambulation After Microsurgical Reconstruction of the Lower Extremity.

Successful outcomes after microsurgical reconstruction of the lower extremity include timely return to ambulation. Some combination of physical examination, ViOptix tissue oxygen saturation monitoring, and the implantable venous Doppler have shown promise in increasing sensitivity of current flap monitoring. We have incorporated this system into our postoperative monitoring protocol in an effort to initiate earlier dependency protocols. A prospective analysis of 36 anterolateral thigh free flap and radial forearm flaps for lower extremity reconstruction was performed. Indications for reconstruction were acute and chronic wounds, as well as oncologic resection. Twenty-three patients were able to ambulate and 3 were able to dangle their leg on the first postoperative day. One flap showed early mottling that improved immediately after elevation. After reelevation and return to baseline, the dependency protocol was successfully implemented on postoperative day 3. All flaps went on to successful healing. Physical examination, implantable venous Doppler, and ViOptix can be used reliably as an adjunct to increase the sensitivity of detecting poorly performing flaps during the postoperative progression of dependency.

Limb-sparing sarcoma reconstruction with functional composite thigh flaps.

INTRODUCTION: Innervated muscle transfer can improve functional outcomes after extensive limb-sparing sarcoma resections. We report our experience using composite thigh flaps for functional reconstruction of large oncologic extremity defects. PATIENTS AND METHODS: Between 2011 and 2014, four limb-sparing oncologic resections (3 lower extremities, 1 upper extremity) underwent immediate functional reconstruction with composite thigh free flaps in three males and one female. The age of the patients ranged from 36 to 73 years. There were 3 soft-tissue sarcomas and one giant cell tumor, all required resection of entire muscle compartments. Flap components included fasciocutaneous tissue with sensory nerve, plicated iliotibial band (ITB), and variable amounts of motorized vastus lateralis (VL). RESULTS: All flaps survived without complications. All patients showed VL motor innervation by six months. Follow-up ranged from 20 to 36 months. Motor strength ranged from 2 to 5 out of 5, active range of motion was 25-92% of normal, and Musculoskeletal Tumor Society (MSTS) Scores were between 22 and 29 out of 30. CONCLUSIONS: Limb-sparing techniques for upper and lower extremity sarcomas continue to evolve. Our experience has validated the composite thigh free flap as an excellent option for one-stage functional reconstruction of large limb defects.

[Surgical indications and complications management in vestibular schwannoma]. / Chirurgische Indikation und Komplikationsmanagement beim Vestibularisschwannom.

BACKGROUND: Recent surgical treatment concepts for patients with vestibular schwannoma (VS) require an interdisciplinary approach as well as recognition and mastering of complications. OBJECTIVE: This paper provides an overview of indications, as well as possible options for function preservation and management of complications in the surgical resection of these tumors. METHODS: Up-to-date treatment concepts and surgical indications were differentiated according to size and extent of tumors. The frequency of important complications was extracted from the literature. Technical options to avoid and correct complications were compiled from personal experience and review of the literature. RESULTS: Complications unrelated to cranial nerves are not infrequent, particularly in older patients. Small and medium-sized tumors that do not reach the fundus and cochlear fossa can be completely removed with good chances of hearing preservation. As long as these tumors do not grow, patients benefit from observation. Large tumors are overrepresented in surgical series compared to their prevalence. Postoperative facial nerve function correlates to tumor volume. Hearing preservation in these tumors is rare. Intraoperative electrophysiological techniques are valuable for attempted preservation of cranial nerve function. Persistent facial palsies can be remedied by dynamic and static interventions for facial rehabilitation. CONCLUSION: Mortality and morbidity associated with surgical treatment of VS are very acceptable. Surgical concepts should be custom-tailored to the individual patient in order to ensure high quality of life.

Effects of dynamic lumbar stabilization exercises following lumbar microdiscectomy on pain, mobility and return to work. Randomized controlled trial.

BACKGROUND: Various lumbar exercise programs are prescribed for rehabilitation purposes following microdiscectomy applied for the treatment of lumbar disk herniation. The literature contains several studies on this subject. However, there are no studies investigating the effects of supervised dynamic lumbar stabilization exercises on fear and fear/regression attitudes of patients and on their return to work. AIM: This study investigates the effects of supervised dynamic lumbar stabilization exercises during postoperative rehabilitation on spinal mobility, pain, functional status, return to work, quality of life, and fear/regression attitude of patients who underwent lumbar microdiscectomy for the first time. SETTING: The study was conducted at physical therapy and rehabilitation clinics. STUDY DESIGN: A randomized clinical trial comparing exercise programs after lumbar microdiscectomy. PATIENTS SAMPLE: Forty-four lumbar microdiscectomy patients were randomized into two groups. OUTCOME MEASURES: Each group was assessed in terms of low back pain, leg pain, spinal mobility, Oswestry Disability Index (ODI), and Nottingham Health Profile (NHP), at the postoperative first, second, and sixth months. Fear/regression beliefs and level of pain were evaluated through the Fear Avoidance Belief Questionnaire (FABQ). METHODS: Forty-four patients were randomly divided into two equal groups of 22 subjects, respectively, as a study group with Dynamic Lumbar Stabilization (DLS) exercises and home exercises, and a control group with only home exercises for a period of four weeks. RESULTS: Leg pain decreased more in the study group compared with the control group (P=0.004). Spinal mobility scores demonstrated greater increases in the study group (P<0.001). Statistically greater reductions were observed in the study group regarding ODI and FABQ scores (P<0.017). CONCLUSION: DLS exercises may be recommended to patients following spinal surgery due to their benefits in reducing pain, increasing spinal mobility, and ensuring faster return to work periods.

Intensive, progressive exercise improves quality of life following lumbar microdiskectomy: a randomized controlled trial.

OBJECTIVE: The purpose of the study was to examine changes in quality of life measures in patients who have undergone an intensive exercise program following a single level microdiskectomy. DESIGN: Randomized controlled trial with blinded examiners. SETTING: The study was conducted in outpatient physical therapy clinics. SUBJECTS: Ninety-eight participants (53 male, 45 female) who had undergone a single-level lumbar microdiskectomy allocated to receive exercise and education or education only. INTERVENTIONS: A 12-week periodized exercise program of lumbar extensor strength and endurance training, and mat and upright therapeutic exercises was administered. OUTCOME MEASURES: Quality of life was tested with the Short Form 36 (SF-36). Measurements were taken 4-6 weeks postsurgery and following completion of the 12-week intervention program. Since some participants selected physical therapy apart from the study, analyses were performed for both an as-randomized (two-group) design and an as-treated (three-group) design. RESULTS: In the two-group analyses, exercise and education resulted in a greater increase in SF-36 scales, role physical (17.8 vs. 12.1) and bodily pain (13.4 vs. 8.4), and the physical component summary (13.2 vs. 8.9). In the three-group analyses, post-hoc comparisons showed exercise and education resulted in a greater increase in the SF-36 scales, physical function (10.4 vs. 5.6) and bodily pain (13.7 vs. 8.2), and the physical component summary (13.7 vs. 8.9) when compared with usual physical therapy. CONCLUSIONS: An intensive, progressive exercise program combined with education increases quality of life in patients who have recently undergone lumbar microdiskectomy.

Brain plasticity in Möbius syndrome after unilateral muscle transfer: case report and review of the literature.

BACKGROUND: Möbius syndrome is mainly characterized by bilateral facial palsy. Facial reanimation of these children is achieved by microsurgical techniques, namely free-gracilis muscle innervated by the masseteric nerve. Notorious commissure excursion and speech improvement are reported with such procedure. Several studies have demonstrated the presence of cortical reorganization after injury and repair of different segments of the body. Intensive training of a behaviorally relevant task is key in this process. CASE REPORT: A 4-year-old patient with complete bilateral facial palsy secondary to Möbius syndrome was operated with left hemiface free-gracilis muscle transplant innervated by the masseteric nerve and submitted for postoperative physiotherapy. Eight months later, bilateral movement was noted. CONCLUSIONS: Brain plasticity is likely to play an important role in smile restoration in patients with bilateral facial palsy. Intensive physiotherapy and psychosocial relevance of facial expression might be key in such phenomenon.

[Long-term outcomes of lumbar microdiscectomy in a working class sample]. / Resultados a largo plazo de la microdiscectomía lumbar en una población labo- ralmente activa.

INTRODUCTION: In the treatment of the lumbar disc herniaton (LDH) microdiscectomy constitutes one of the standard procedures. In the present study we have analyzed the clinical outcome of the lumbar microdis- cectomy in a series of worker patients who underwent surgery in our service. METHODS: Retrospective analysis and a 5-year follow up, of a series of 142 patients operated on by means of lumbar microdiscectomy in the 2004-2005 period. The clinical outcome was analyzed according to the "Herron and Turner" outline: pain reduction, use of medical treatment, restriction in the ability to perform physical activities, and return to work. RESULTS: 116 men and 26 women, with an average age of 37.9 and 45.4 years respectively, underwent surgery because of LDH. In the clinical aspect, sciatica was predominant over low back pain in a ratio of three to one. The L5-S1 discal level was operated on in 68.3% of the cases. It was considered that occupational activities gave rise to damage in 107 patients (75.3%). Besides a symptomatic disc, there was an additional injured disc in 44.3% of the cases. An initial unfavourable outcome was seen in 42 patients (33%), 15 of which recovered from in an interval of 3 months, and another fifteen within a one year period. A re-operation was necessa ry in 16 patients because of recurrent lumbar disc herniation (11%). Work reintegration was achieved in 83.3% (119/142) of the cases. After a 5-year follow up, we stated the consistency of the clinical result. DISCUSSION: We analyzed the intervertebral disc behaviour as regards sex, age, variety of discal herniation, additional disc, outcome and re-operation variables. After the analysis of the type of discal herniation and additional disc we defined three disc injury patterns. We consider microdiscectomy as the technique of choosing for the treatment of recurrence disc herniation. CONCLUSIONS: Between the working class, discal injury predominates in young men, as a consequence of the annulus breakage, or an annulus plus posterior longitudinal ligament breakage (traumatic herniae). Frequently it was observed that more than one disc was involved, and a left lateralization.

Return to golf after spine surgery.

OBJECT: no published evidence indicates when patients can resume golfing after spine surgery. The objective of this study is to provide data from surveys sent to spine surgeons. METHODS: a survey of North American Spine Society members was undertaken querying the suggested timing of return to golf. Of 1000 spine surgeons surveyed, 523 responded (52.3%). The timing of recommended return to golf and the reasons were questioned for college/professional athletes and avid and recreational golfers of both sexes. Responses were tallied for lumbar laminectomy, lumbar microdiscectomy, lumbar fusion, and anterior cervical discectomy with fusion. RESULTS: the most common recommended time for return to golf was 4-8 weeks after lumbar laminectomy and lumbar microdiscectomy, 2-3 months after anterior cervical fusion, and 6 months after lumbar fusion. The results showed a statistically significant increase in the recommended time to resume golf after lumbar fusion than after cervical fusion in all patients (p < 0.01). The same holds true for the return to play after cervical fusion compared with either lumbar laminectomy or lumbar microdiscectomy for all golfer types (p < 0.01). There was a statistically significant shorter recommended time for professional and college golfers compared with noncompetitive golfers after lumbar fusion (p < 0.01), anterior cervical discectomy and fusion (p < 0.01), and lumbar microdiscectomy (p < 0.01). CONCLUSIONS: the return to golf after spine surgery depends on many variables, including the general well-being of patients in terms of pain control and comfort when golfing. This survey serves as a guide that can assist medical practitioners in telling patients the average times recommended by surgeons across North America regarding return to golf after spine surgery.

The significance of microsurgical varicocelectomy in the treatment of subclinical varicocele.

OBJECTIVE: To assess the improvement of seminal characteristics and pregnancy rates after microsurgical varicocelectomy in men with subclinical varicocele. DESIGN: Retrospective study. SETTING: University infertility clinic. PATIENT(S): One hundred forty-three patients with a subclinical left-sided varicocele. INTERVENTION(S): Patients who agreed to microsurgical varicocelectomy (n = 25, surgery group), medical treatment with L-carnitine (n = 93 drug group), and those who did not agree to any treatment (n = 25, observation group) were enrolled. MAIN OUTCOME MEASURE(S): Semen characteristics were reevaluated twice 6 months after treatment. The natural pregnancy rates were estimated by telephone interview between 1 and 2 years after treatment. RESULT(S): In the surgery group, sperm counts improved significantly after microsurgical varicocelectomy. In the drug group, however, sperm parameters did not significantly improve after treatment. Natural pregnancy rates were 60.0% in the surgery group, 34.5% in the drug group, and 18.7% in the observation group. The natural pregnancy rate of the surgery group was higher than the other groups, and there were statistically significant differences among the three groups. CONCLUSION(S): Surgical treatment is the best option for management of subclinical varicocele.

Clinical factors determining pregnancy outcome after microsurgical tubal reanastomosis.

OBJECTIVE: To evaluate pregnancy rates after tubal microsurgical anastomosis. DESIGN: Retrospective study. SETTING: Private tertiary care center. PATIENT(S): Two hundred sixty-one women undergoing tubal microsurgical anastomosis. INTERVENTION(S): Tubal anastomoses were performed by minilaparotomy using microsurgical principles and approximating proximal and distal tubal ends in a two-layer technique with 8-0 ethylon. MAIN OUTCOME MEASURE(S): Pregnancy outcome was analyzed for the technique of sterilization, location of anastomosis, tubal length, age, and semen parameters. RESULT(S): After exclusion of 89 patients lost to follow-up (34%) and 8 who did not attempt to conceive, 164 of the 261 patients were analyzed.The overall intrauterine pregnancy rate was 72.5%, with a miscarriage rate of 18% and a tubal pregnancy rate of 7.7%. Related to age, the cumulative intrauterine pregnancy rate was, respectively, 81%, 67%, 50%, and 12.5% for patients <36, 36-40, 40-43, and >43 years. Mean time to pregnancy was respectively 6.9, 6.2, and 12.7 months, respectively, for patients aged <36, 36-39, and 40-43 years According to the type of sterilization, intrauterine pregnancies occurred in 72% after ring sterilization, 78% after clip sterilization, 68% after coagulation, and 67% after Pomeroy sterilization. Intrauterine pregnancies and ectopic pregnancies, respectively, occurred in 80% and 3.4% in the isthmo-isthmic, 63% and 18% in the isthmo-ampullar, 75% and 8.3% in the isthmo-cornual, 100% and 0% in the ampullo-ampullar, and 60% and 0% in the ampullo-cornual anastomosis groups. Tubal length after anastomosis did not influence the pregnancy rate. In case of fertile sperm, the pregnancy rate was found to be 80%, and it decreased to 50% in case of subfertile semen. CONCLUSION(S): Our results clearly demonstrate the validity of tubal microsurgical anastomosis, establishing a quasinormalization of the fertility potential and offering the opportunity for a spontaneous conception.

Role of timing in assessment of nerve regeneration.

Small animal models are indispensable for research on nerve injury and reconstruction, but their superlative regenerative potential may confound experimental interpretation. This study investigated time-dependent neuroregenerative phenomena in rodents. Forty-six Lewis rats were randomized to three nerve allograft groups treated with 2 mg/(kg day) tacrolimus; 5 mg/(kg day) Cyclosporine A; or placebo injection. Nerves were subjected to histomorphometric and walking track analysis at serial time points. Tacrolimus increased fiber density, percent neural tissue, and nerve fiber count and accelerated functional recovery at 40 days, but these differences were undetectable by 70 days. Serial walking track analysis showed a similar pattern of recovery. A "blow-through" effect is observed in rodents whereby an advancing nerve front overcomes an experimental defect given sufficient time, rendering experimental groups indistinguishable at late time points. Selection of validated time points and corroboration in higher animal models are essential prerequisites for the clinical application of basic research on nerve regeneration.

Reconstrução microcirúrgica em cirurgia de cabeça e pescoço. Opções e soluções para defeitos complexos / Head and neck microsurgical reconstruction options and solutions for complex defects

Câncer em cabeça e pescoço é entidade muito comum nos países em desenvolvimento. Nos defeitos pe- quenos ou não complexos, podemos utilizar da várias opções para reconstrução, como retalhos locais ou pedículadosadistância,masquandonosdeparamoscom defeitos grandes ou complexos, microcirurgia torna-se necessária.

Introduction: head and neck cancer are very common entities of developing countries. In small or non complex defects we have a lot of options for reconstruction, like local or pedicle flaps, but when we consider big or complex defects microsurgery is necessary. Methods: in our casuistic, we have used radial forearm free flap for oral cavity, tongue and faryngeal defects, free anterolateral thigh flap with vastus lateralis muscle for maxilla defects and free fibula flap for mandible defects, between 20 patients. All flaps were done in the same institution and by the same surgical team. Results: the most common complications observed in microsurgical flaps like venous thrombosis and hematoma were not observed in this casuistic of 20 cases. Conclusion: microsurgical flaps for head and neck reconstruction represent an excellent alternative for big and complex defects, with low complication rates.

The immediate and long-term effects of exercise and patient education on physical, functional, and quality-of-life outcome measures after single-level lumbar microdiscectomy: a randomized controlled trial protocol.

BACKGROUND: Low back pain remains a costly quality-of-life-related health problem. Microdiscectomy is often the surgical procedure of choice for a symptomatic, single-level, lumbar disc herniation in younger and middle-aged adults. The question of whether a post-microdiscectomy exercise program enhances function, quality of life, and disability status has not been systematically explored. Thus, the overall purpose of this study is to assess immediate and long-term outcomes of an exercise program, developed at University of Southern California (USC), targeting the trunk and lower extremities (USC Spine Exercise Program) for persons who have undergone a single-level microdiscectomy for the first time. METHODS/DESIGN: One hundred individuals between the ages of 18 and 60 who consent to undergo lumbar microdiscectomy will be recruited to participate in this study. Subjects will be randomly assigned to one of two groups: 1) one session of back care education, or 2) a back care education session followed by the 12-week USC Spine Exercise Program. The outcome examiners (evaluators), as well as the data managers, will be blinded to group allocation. Education will consist of a one-hour "one-on-one" session with the intervention therapist, guided by an educational booklet specifically designed for post-microdiscectomy care. This session will occur four to six weeks after surgery. The USC Spine Exercise Program consists of two parts: back extensor strength and endurance, and mat and upright therapeutic exercises. This exercise program is goal-oriented, performance-based, and periodized. It will begin two to three days after the education session, and will occur three times a week for 12 weeks. Primary outcome measures include the Oswestry Disability Questionnaire, Roland-Morris Disability Questionnaire, SF-36 quality of life assessment, Subjective Quality of Life Scale, 50-foot Walk, Repeated Sit-to-Stand, and a modified Sorensen test. The outcome measures in the study will be assessed before and after the 12-week post-surgical intervention program. Long-term follow up assessments will occur every six months beginning one year after surgery and ending five years after surgery. Immediate and long-term effects will be assessed using repeated measures multivariate analysis of variance (MANOVA). If significant interactions are found, one-way ANOVAs will be performed followed by post-hoc testing to determine statistically significant pairwise comparisons. DISCUSSION: We have presented the rationale and design for a randomized controlled trial evaluating the effectiveness of a treatment regimen for people who have undergone a single-level lumbar microdiscectomy.

Vestibular schwannomas: clinical results and quality of life after microsurgery or gamma knife radiosurgery.

OBJECTIVE: The aim of the present study was to evaluate the overall treatment efficacy (tumor control, facial nerve function, complications) and quality of life for patients treated primarily for unilateral vestibular schwannomas of 30 mm or less, either by microsurgery or by gamma knife (GK) radiosurgery. The results for the two treatment groups are compared with each other, with main emphasis on the long-term quality of life. METHODS: This is a retrospective study of 189 consecutive patients, 86 treated by microsurgery and 103 by gamma knife. The mean observation time was 5.9 years. All patients had a magnetic resonance imaging scan and clinical evaluation performed toward the end of the study. To evaluate the quality of life, we used two standardized questionnaires, the Glasgow Benefit Inventory and Short-Form 36. The questionnaires were sent to the 168 living patients. The reply rate was 83.3%. RESULTS: A total of 79.8% of the patients in the microsurgery group and 94.8% of the GK patients had a good facial nerve function (House-Brackmann Grade 1-2). Hearing was usually lost after microsurgery, whereas the GK patients had preserved hearing, which often became reduced over the years after the treatment. The treatment efficacy, defined as no need for additional treatment, was similar for the two treatment modalities. Quality of life was reduced compared with normative data, being most reduced in the microsurgery group. Some of the quality of life questions showed an association with facial nerve function and sex. CONCLUSION: Posttreatment facial nerve function, hearing, complication rates, and quality of life were all significantly in favor of GK radiosurgery.

Anterolateral thigh flap: an ideal soft tissue flap.

Microsurgical reconstruction has evolved to a stage where a nearly 100% success rate has been achieved. Therefore, refinement of the functional and aesthetic result, as well as a decrease in donor site morbidity have become the major concerns. The anterolateral thigh flap meets these requirements; its wide application to various fields is based on the following charateristics. Its reliable vascularity. Its vascular pedicle is long and large, at least 8 cm (can be 20 cm). Flap territory is large and easy to design. The pedicle can be at the periphery of the flap. Its length can be 40 cm and its width can be half of the thigh, with the maximal dimension as large as 40 x 20 cm (800 cm2). Primary trimming of the flap to 3 mm to 5 mm in thickness does not compromise its vascularity. The subcutaneous fat can be included to facilitate gliding of the underlying tendons. To harvest chimeric flaps, the following components can be included: muscles, fascia and bone (an osseous flap can be joined to the flap with microvascular anastomoses). A two-team approach is possible, because the recipient site is usually far away from the donor site. Usually it does not require that the patient change position. It can be closed primarily without skin graft if its width is less than 8 cm. The donor site is easily covered with clothes, and the motor function is least affected. Care should be taken in flap dissection, inset, and postoperative care, as well as strategies for re-exploration.

Quality of life before and after microsurgical decompression in lumbar spinal stenosis.

Twenty consecutive patients (10 men and 10 women; median age, 68 years) with lumbar spinal stenosis were studied before and after microsurgical decompression without laminectomy. Fourteen of the patients had pure stenosis symptoms, whereas six had intercurrent diseases that could exacerbate the symptoms of stenosis. The mean duration of symptoms was 4.5 years (range, 1 to 15 years). All patients were interviewed before operation, and an assessment form based on and modified from the Oswestry Low Back Pain Disability Questionnaire was completed. The ability to perform physical activities including house work, gardening, going to the post office, and so forth was markedly reduced before operation for nearly all patients, and social life such as traveling, meeting friends, and participating in hobbies was similarly restricted. Sleeping was also greatly affected before operation, as were psychological parameters including irritability, depression, infirmity, energy, patience, and concentration. At follow-up 2.8 years after surgery, 13 of the 14 patients with pure stenosis evaluated their quality of life as much improved and principally normal. Among the patients with intercurrent diseases, only two of six judged the quality of their lives as much improved.
