Is saphenofemoral junction reconstruction necessary during stripping of the saphenous vein?

BACKGROUND: Patients who had undergone complete ankle-to-groin stripping of the greater saphenous vein were evaluated retrospectively to assess the necessity of saphenofemoral junction reconstruction during the stripping procedure. Since 1996, in addition to the conventional complete stripping operation, we routinely perform a saphenofemoral junction reconstruction in patients presenting with greater saphenous vein reflux associated with low-grade (grades I-II) saphenofemoral junctional reflux. In this method, the size of the common femoral vein was adjusted to the desired diameter by a running linear suture technique after division of the greater saphenous vein. METHODS: Retrospective evaluation revealed that 73 limbs in 56 patients treated with this technique (group I). This group of patients was matched to another group of 65 patients (78 limbs) with similar characteristics and symptoms (group II) in whom the conventional complete ankle-to-groin stripping of greater saphenous vein was the treatment. The 2 groups were compared with respect to the incidence of complications, including recurrence of varicosities, ecchymosis, lymphocele, lymphorrhagia, wound infection, and paresthesia in the operated extremity. All patients also were evaluated by Doppler ultrasonography at 6 months, 12 months, and annually thereafter to determine the saphenofemoral junction reflux time (valve reflux time). The mean duration +/- SD of follow-up was 6.7 +/- 1.6 years (range, 2.1-10.8 years). RESULTS: Recurrence of varicosity was noted in 14 patients, 3 in group I and 11 in group II (P = .02). There were no statistically significant differences between the 2 groups in terms of ecchymosis, hematoma, lymphocele, lymphorrhagia, wound infection, and paresthesia. At 6 months, a rapid decrease in valve reflux time was noted in group I (P = .0001). In addition, there was a significant improvement in valve reflux time at each subsequent Doppler examination in group I. Group II showed a decrease in valve reflux time, compared with the preoperative value (P = .068). During subsequent Doppler examinations, a decrease in valve reflux time also was noted in group II; this difference reached statistical significance only at 24 months (P = .04). CONCLUSIONS: We believe that saphenofemoral junction reconstruction is a simple technique to perform and that addition of this method to the conventional stripping provides more durable results with a lesser incidence of recurrence. This method should be considered as a treatment modality in patients with greater saphenous vein reflux associated with low-grade (grades I-II) saphenofemoral junctional reflux.     

Infrainguinal arterial reconstruction with autologous vein grafts: are the results for the in situ technique better than those of non-reversed bypass? A long-term follow-up study

BACKGROUND: The aim of this study was to answer the question if the in situ technique in infrainguinal arterial reconstruction is better than the non reversed one in long-term follow-up. METHODS: Patients were included in a prospective study at operation. 387 infrainguinal arterial reconstructions in 367 patients performed from 10-88 to 12-98 were retrospectively analysed. RESULTS: 280 non-reversed and 107 in situ bypass procedures were performed. Primary patency rates at 60 months were 63.3% for non-reversed and 57.9% for in situ grafts (p=n.s.). Primary assisted patency rates were 81.8% and 84.5% respectively (p=n.s.). Limb salvage rate was not different in either group. The 30-day mortality was 1.9% in the in situ group and 0.7% in the non-reversed group (p=n.s.). CONCLUSIONS: There is no difference in outcome between in situ and non-reversed vein grafting. Absence of statistical difference between the two procedures may be mainly due to the routine use of angioscopic quality control.     

Is repeated repair of the meniscus worthwhile?

Meniscal injuries are one of the most commonly encountered problems by orthopaedic surgeons. It is well established that meniscectomy will result in increased joint surface contact forces and the predictable progression of arthritis. The management of meniscal tears has evolved and current evidence would suggest that every attempt should be made to repair meniscal tears when appropriate. The reported success rate of meniscal repair is encouraging, but relatively little is known about the outcome of repeated repair of a re-torn meniscus. This review presents an illustrative case of a recurrent lateral meniscal tear in a young female, that has required surgical repair on three occasions over a fourteen year period. Despite recurrent tears of her lateral meniscus, the patient was symptom-free in the intervening periods and at her latest operation, her articular cartilage showed minimal evidence of chondral damage. Longer-term follow-up is required to determine whether repair of a re-torn meniscus prevents the progression of degenerative changes within the knee joint that is associated with meniscectomy.     

Is open synovectomy of the metacarpophalangeal joint in chronic polyarthritis worthwhile?

PURPOSE/METHODS/PATIENTS: This work retrospectively analysed 252 synovectomies performed on 153 patients from 1958 to 1995 at the Balgrist University Orthopaedics Clinic, and evaluated the short-term and long-term benefits of open synovectomy of the metacarpo-phalangeal joint in rheumatoid arthritis. RESULTS: Rheumatoid arthritis (n = 182) was by far the most common of the 21 different diagnoses involved, and the metacarpo-phalangeal joint (n = 101) was by far the most frequently operated of the 7 different joint types in question. In the short tenn (n = 97), after a mean of 5.5 months, open synovectomy of a metacarpo-phalangeal joint in rheumatoid arthritis patients provided a benefit in terms of mobility in 85% of cases and in terms of joint swelling and pain in 93% of cases. Among one-third of the originally operated cases (n = 38), long-term benefit, i.e. after a mean of 6.9 years, was obtained in 89% of cases with regard to joint mobility, 87% with regard to swelling and 97% with regard to pain relief. Two-thirds of the joints presented normal mobility and swelling, and three-quarters were pain-free. CONCLUSIONS: The metacarpo-phalangeal joint is very important for maintaining the independence of a patient (gripping). Open synovectomy of the metacarpo-phalangeal joint in rheumatoid arthritis patients is an effective therapeutic procedure with little morbidity and very good long-term benefit in the management of metacarpo-phalangeal pain, swelling and stiffness refractory to conservative therapy.     

Is it worthwhile to screen the hip in infants born with clubfeet?

Purpose

There is some disagreement about whether idiopathic congenital talipes equinovarus (CTEV) increases the risk of neonatal developmental dysplasia of the hip (DDH). This study aimed to investigate the incidence of DDH in our infants with idiopathic CTEV.

Methods

We conducted an observational cohort study over a three-year period to assess the relationship between idiopathic CTEV and DDH. All neonates younger than six weeks with idiopathic CTEV who were treated in our medical centre were admitted to this study. Each subject underwent hip ultrasound examination using the Graf method at the age of six weeks. DDH was diagnosed when a hip was type IIa(−) or worse according to the Graf classification of sonographic hip type.

Results

A total of 184 patients were diagnosed with idiopathic CTEV and underwent hip sonography. In total, seven hips of five individuals underwent treatment (four girls and one boy). The results indicated that 2.7 % of babies (five of 184) with idiopathic CTEV had DDH. However, we did not find any statistically significant difference (p = 0.5776) in the Pirani scores between the DDH group and group with normal hips.

Conclusions

This study revealed that the idiopathic CTEV group had a greater incidence of DDH in comparison with the general population. It is recommended that hip sonography be undertaken particularly in patients with idiopathic CTEV.     

Is there a role for arterial reconstruction in surgery for pancreatic cancer?

Surgery remains the only potentially curative treatment for patients with pancreatic cancer. Locally advanced pancreatic cancer with vascular involvement remains a surgical challenge because high perioperative risk and the uncertainty of a survival benefit. Whilst portal vein resection has started to gather momentum because the perioperative morbidity and long term survival is comparable to standard pancreatectomy, there isn’t yet a consensus on arterial resections. There have been various reports and case series of arterial resections in pancreatic cancer, with mixed survival results. Mollberg et al have appraised the heterogeneous published literature available on arterial resection in pancreatic cancer in an attempt to compare this to standard pancreatectomy. In this article, we discuss the results of this systematic review and meta-analysis, and the limitations associated with analysing results from heterogenous data. We have outlined the important features in surgery for pancreatic cancer and specifically to arterial resections, and compared arterial resections to the published literature on venous resections.     

Is minimal reconstruction (meshplasty) adequate to restore ankle function after excision of distal fibula tumors?

BackgroundReconstruction modalities described after distal fibula resection varies from no reconstruction to size matched allograft or reconstruction with ipsilateral proximal fibula. Every procedure has their own limitation. We used Prolene mesh to reconstruct lateral restraint (Meshplasty) after distal fibulectomy.QuestionIs a minimal reconstruction using prolene mesh (meshplasty) adequate to restore ankle stability and function post distal fibula resection?MethodThis retrospective analysis was performed in patients who underwent distal fibulectomy at the tertiary cancer hospital in India, between 01/01/2006 and 31/12/2016. Distal fibulectomy was performed through standard lateral approach. A prolene mesh was anchored to distal tibia and talus using screws or Ethibond sutures. Rehabilitation protocol included below knee cast for 6 weeks followed by gradual full weight bearing mobilization and ankle range of motion. Total 9 patients with mean age of 25 years (range: 13–43) got operated for distal fibulectomy during this period. Mean resection length was 13.3 cm (range: 9–20).ResultsSeven patients were available for final assessment at a median follow-up duration of 78 months (range: 34–161 months). Two patients developed local recurrence. Two patients developed distant recurrence both died of disease. One patient of GCT developed local recurrence in soft tissue at 30months, which was excised. Another patient of OGS developed local recurrence after 8 months along with distant recurrence. One patient of PNET developed distant recurrence at 3 months. One patient had a valgus deformity at 55 months follow up without any restriction of activity while the others had a stable ankle without any deformity. The mean MSTS score was 28 (24–29).Conclusion“Meshplasty” after distal fibulectomy is an easy, reproducible, time and cost effective reconstruction modality with minimal complications. It adequately restores ankle function while providing results comparable to other procedures.Level of evidenceIV.     

Infrainguinal arterial reconstruction for claudication: Is it worth the risk? An analysis of 409 procedures

Purpose: Infrainguinal reconstruction traditionally has been reserved for patients with limb-threatening ischemia. Surgery for debilitating claudication, however, has been discouraged as a result of the perceived fear of bypass graft failure, limb loss, and significant perioperative complications that may be worse than the natural history of the disease. In this study, the results of infrainguinal reconstructions for claudication performed during the past 10 years were evaluated for bypass graft patency, limb loss, and long-term survival rates. Methods: Data were collected and reviewed from the vascular registry, the office charts, and the hospital records for patients who underwent infrainguinal bypass grafting for claudication. Results: From 1987 to 1997, 409 infrainguinal reconstructions were performed for claudication (9% of all infrainguinal reconstructions in our unit). The patient population had the following demographics: 73% men, 28% with diabetes, 54% smokers, and an average age of 64 years (range, 24 to 91 years). Inflow was from the following arteries: iliac artery/graft, 10%; common femoral artery, 52%; superficial femoral artery, 19%; profunda femoris artery, 16%; and popliteal artery, 2%. The outflow vessels were the following arteries: 165 above-knee popliteal arteries (40%), 150 below-knee popliteal arteries (37%), and 94 tibial vessels (23%). The operative mortality rate was 0%, and one limb was lost in the series from distal embolization. The primary patency rates were 62%, 77%, and 86% for above-knee popliteal artery, below-knee popliteal artery, and tibial vessel reconstructions at 4 years, and the secondary patency rates were 64%, 81%, and 90%, respectively. Cumulative patient survival rates were 93% and 80% at 4 and 6 years as compared with 65% and 52%, respectively, for infrainguinal reconstructions performed for limb salvage. Conclusion: Infrainguinal arterial reconstruction for disabling claudication is a safe and durable procedure in selected patients. These data indicate that concern for limb loss, death, and limited life span of the patients with this disease may not be warranted. (J Vasc Surg 1999;29:259-69.)     

Is the determination of prostatic acid phosphatase still worthwhile in prostate cancer patients?

With the introduction of prostatic specific antigen (PSA), the role of prostatic acid phosphatase (PAP) has been questioned. Some authors still advocate its determination, because PAP may be helpful for identifying patients with organ confined cancer. Tumor progression may be detected earlier in some patients by PAP. With respect to cost, we analyzed whether PAP still has a place as a tumor marker for prostate cancer (PC). In 6,151 men seen for screening or treatment of PC or therapy of benign prostatic hyperplasia (BPH), parallel determinations of PAP and PSA were done. PC was diagnosed in 862 patients, BPH in 5,503 patients, and prostatitis in 86 patients. There were only 16 patients with PSA < 4 ng/ml and PAP > 5 ng/ml. Five of 16 patients had histologically proven BPH; 11 of 16 patients suffered from metastatic PC. Five of 11 patients were in remission on hormonal therapy; PSA had already normalized and PAP was still elevated. Three of I I patients had hormone resistant PC; PAP detected the progression earlier than PSA. In the absence of an effective treatment, this is not of clinical relevance. In 1 of 11 patients, a falsely low value was assumed. In all, 935 of 6,151 patients showed normal PAP and elevated PSA; 805 of 935 patients suffered from BPH or prostatitis; 130 of the 935 patients had PC. Stage D was found in 56 of 130 patients, stage C in 31 patients, and stage A B in 43 patients, which did not allow the identification of organ confined cancer. Therefore, there is no benefit from the determination of PAP in PC. It is both safe and cost-effective to abandon PAP as a tumor marker for PC.     

Revision hip surgery in the elderly: Is it worthwhile?

We prospectively analyzed the outcome in 103 consecutive patients undergoing revision hip replacement, dividing the patients into 2 groups according to their age at the time of surgery. There were 45 patients aged 75 years or older and 58 patients aged younger than 75 years. The results of revision hip replacement in terms of pain relief, functional improvement, and patient satisfaction did not differ between the 2 groups. There was a significantly higher death rate among the elderly patients (13.3% versus 1.7%; P = .0202) and a significantly higher rate of dislocation (20% versus 1.7%; P = .0019). We conclude that revision hip replacement is an effective operation in the elderly, but that patient and surgeon must be aware of the risks that such surgery entails.     

Is renal revascularization in diabetic patients worthwhile?

Purpose: This retrospective review describes surgical management of atherosclerotic renovascular disease (RVD) in hypertensive adults with diabetes mellitus.Methods: From July 1987 through July 1995, 54 consecutive hypertensive diabetics (mean 213/103 mm Hg; mean medications three drugs) requiring either insulin (16 patients) or oral hypoglycemic therapy (38 patients) had operative repair of atherosclerotic RVD. Renal dysfunction (serum creatinine [SCr] ≥1.3 mg/dl) was present in 82% of patients (mean SCr 2.4 mg/dl). Associations between blood pressure and renal function response to operation and preoperative parameters were examined. Clinical characteristics, response to operation, and dialysis-free survival were compared with those of 291 nondiabetic patients.Results: Four (7.4%) operative deaths occurred. Among 50 survivors blood pressure response was considered cured or improved in 72% and unchanged in 28%. Of 42 patients with renal dysfunction 40% had improved function including three patients removed from dialysis. No preoperative parameter examined demonstrated a significant association with blood pressure or renal function response. During follow-up 10 additional patient deaths occurred, and eight patients progressed to dialysis dependence. Time to death or dialysis was associated with preoperative estimates of glomerular filtration (p = 0.03) and the change in estimates of glomerular filtration after operation (p = 0.01). Compared with 291 nondiabetics, the diabetic group had no statistical difference in improved function response (40% vs 51%, p = 0.21); however, diabetics had a significantly lower rate of beneficial blood pressure response (72% vs 89%, p = 0.01) and an increased risk of dialysis or death during follow-up (p = 0.02). By multivariate analysis independent predictors of time to death or dialysis included the presence of diabetes mellitus, patient age, history of congestive heart failure, and increased serum creatinine.Conclusions: Most of the selected diabetic patients had a beneficial blood pressure response after undergoing operative repair of atherosclerotic RVD, albeit at a lower rate compared with nondiabetics. In diabetics poor renal function before and after operation was associated with progression to dialysis and death. Improved renal function after operation was associated with improved survival; however, function response to renal revascularization was difficult to predict. (J Vasc Surg 1996;24:383-93.)     

Is laparoscopic approach to lumbar spine fusion worthwhile?

BACKGROUND: Laparoscopic lumbar spine fusion has been recently described. The aim of this study is to evaluate the safety and efficacy of this procedure for single- and multiple-level degenerative disc disease. METHODS: Twenty-four consecutive laparoscopic interbody lumbar fusions were evaluated prospectively (18 single-level were compared with 6 multiple-level procedures). Results of the laparoscopic multiple-level procedures were further compared with 12 open multiple-level operations. RESULTS: Twenty procedures were completed laparoscopically. The conversions were related to iliac vein lacerations (3 cases) and a mesenteric tear. Single-level cases had lower morbidity (22% versus 83%), shorter hospital stay (2 versus 10 days), and higher fusion rate (88% versus 50%) than multiple-level procedures. Overall results in the latter group were worse than in the matched open group. CONCLUSIONS: Laparoscopic single-level fusion (L5-S1) is safe and carries the benefits of minimal access surgery. Morbidity after multiple level approach is high, and this procedure cannot be advocated at this time.     

Is prevention of stone recurrence financially worthwhile?

This review shows that the cost of relying solely on minimally-invasive urological procedures for removing stones when patients return with recurrent stones is considerable and is significantly greater that that incurred by screening already proven recurrent stone-formers to identify the risk factors that are causing their stones and then instituting prophylactic measures to prevent stone recurrence. In the UK, at 1998 prices (when the original survey was carried out) for every stone episode prevented, there is a potential saving of almost ￡2,000 to the local Health Authority concerned. In spite of this, many Health Authorities have taken the liberty to discontinue comprehensive stone screening within the past 20 years under the mistaken supposition that minimally-invasive techniques for removing stones have “solved the stone problem”. At UCLH in London where such a comprehensive scheme has been in place for the past 8 years, savings of up to ￡250,000 per year can be made by identifying the particular lifestyle as well as the epidemiological, metabolic and nutritional risk factors involved in a given patient and then instituting appropriate measures to prevent further stones.
