Mediastinal neurogenic tumors and video-assisted thoracoscopy: always the right choice?

Neurogenic mediastinal tumors in adults are generally benign lesions and for this reason are ideal candidates for resection by video-assisted thoracoscopy (VAT). Usual contraindications to VAT are the dimension of the tumor (greater than 6 cm), its position (apex, posterior costodiaphragmatic angle), and/or the presence of intraspinal growth (the so-called "dumbbell tumors"). This study reviewed a single-institution 10-year experience approaching mediastinal neurogenic tumors routinely by VAT, even in cases of the above mentioned contraindications. From January 1992 to December 2002, 15 consecutive mediastinal neurogenic tumors were operated by VAT (11 females, mean age 43 years, range 16-67). Mean operating time was 99 minutes (range 60-180). No conversion thoracotomy was required. The 2 cases of "dumbbell tumor" in this series were treated by laminectomy followed by VAT. Two patients had a Claude-Bernard-Horner syndrome after removal of lesion at the level of T1-T2. Mean postoperative stay was 5.5 days. Histologic diagnosis was schwannoma in 12 cases (Antoni type A in 7 cases, type B in 4 cases, mixed type in 1 case) and neurofibroma in 3 cases. Results from this 10-year experience confirmed that VAT can be the standard approach for neurogenic tumors in adults without negative effect on radicality of resection and safety of the procedure.

OLIF versus ALIF: Which is the better surgical approach for degenerative lumbar disease? A systematic review

Purpose

The aim of this study was to compare the clinical and radiographical outcomes between OLIF and ALIF in treating lumbar degenerative diseases.

Methods

We searched PubMed, Embase, Web of Science, and Cochrane Library for relevant studies. Changes in disc height (DH), segmental lordosis angle (SLA), lumbar lordosis (LL), visual analogue scale (VAS) score, and Oswestry disability index (ODI) between baseline and final follow-up, along with other important surgical outcomes, were assessed and analysed. Data on the global fusion rate and main complications were collected and compared.

Results

Approximately, 2041 patients from 36 studies were included, consisting of 1057 patients who underwent OLIF and 984 patients who underwent ALIF. The results reveal no significant difference in DH, SLA, VAS score, and ODI between the two groups (all P > 0.05). The operation time, estimated blood loss, and length of hospital stay were also comparable between the two groups. Over 90% of the fusion rate was achieved in both groups. The OLIF group showed a higher complication rate than the ALIF group (OLIF 18.83% vs ALIF 7.32%).

Conclusions

OLIF leads to a higher complication rate, with the most notable complication being cage subsidence. Both OLIF and ALIF are effective treatments for degenerative lumbar diseases and have similar therapeutic effects. ALIF was expected to be more expensive for patients because of the necessity of involving vascular surgeons.

     

Sacrocolpopexy: is there a consistent surgical technique?

Introduction

Sacrocolpopexy is the gold standard treatment for vault prolapse. Current reported standards regarding surgical approach and technique vary. Our aim was to evaluate the surgical techniques used and identify any consistency.

Methods

Electronic surveys were sent to 148 candidates enrolled in a sacrocolpopexy workshop at the 2012 American Urogynecologic Society (AUGS) annual meeting and as a link in the International Urogynecology Association (IUGA) e-magazine. The survey assessed demographics, specific surgical steps including dissection techniques, number and type of sutures, graft materials, and the approach to intraoperative complications.

Results

Within the AUGS group, 61 candidates responded (41 %). From the IUGA membership, 128 responded for a total of 189. Overall, 59 % identified their primary practice as urogynaecology, 43 % having completed a fellowship. Only 33 % reported performing sacrocolpopexy as the primary surgery for vault prolapse. Technical aspects: 99.4 % used polypropylene mesh, with 57 % attaching it to the vagina using non-absorbable monofilament sutures. An average of 3–4 sutures were used on the anterior and posterior walls respectively. Suture location: 22.5 % reported not placing apical sutures and 55.7 % place their anterior wall sutures midway down the vagina. Posteriorly, 47 (30 %) placed sutures through the uterosacral ligaments, 19 (12.4 %) through the levator ani and 15 % extend the mesh to the perineal body. The mesh was attached to the sacrum using permanent sutures by 75 %. Dissection of the sacrum was deemed the most technically difficult aspect.

Conclusion

Surgical technique varies widely despite the level of expertise and training. This study highlights the need for an evaluation of the effect of surgical technique on outcomes.

     

The new consent form: is it any better?

BACKGROUND: The UK Department of Health (DoH) introduced a new consent form into the National Health Service (NHS) in April 2002 following the Bristol Royal Infirmary Inquiry. AIM: To compare the efficacy of the new consent form with the old on the quality of consent. METHODS: A questionnaire consisting of 11 questions was distributed to two groups of 100 patients before and after the introduction of the new consent form in the pre-assessment clinic at Glenfield Hospital, Leicester. RESULTS: Of the 11 questions, there were four significant differences that favoured the new consent form. These were: (i) success and benefits of the operation (old, 81%; new, 97%, P < 0.001; 95% CI, 7.3-24.4%); (ii) information that patients received about the operation from the doctor (old, 34%; new, 93%; P < 0.001; 95% CI, 46.7%-68.9%) and nurse (old, 21%; new, 67%; P < 0.001; 95% CI, 33.3-58.3%) in the pre-assessment clinic; (iii) postoperative recovery (old, 56%; new, 96%; P < 0.001; 95% CI, 30.0%-51.2%); and (iv) ability to list potential complications that could arise from the operation (old, 61%; new, 97%; P < 0.001; 95% CI, 26.4-52.6%). Despite the above differences, an overall assessment involving all questions failed to show a significant improvement with the new consent form (old, 57%; new, 67%; P = 0.264;, 95% CI, -35.6% to 12.6%). DISCUSSION AND CONCLUSIONS: The new consent form resulted in improvement in some, but not all, aspects of consent and no question reached the ideal standard of 100%. We suggest a formatted consent form for procedures in conjunction with additional information.     

Appendectomy during early pregnancy: what is the preferred surgical approach?

Appendectomy is the most common nongynecologic surgery performed during pregnancy. Although many surgeons offer laparoscopic appendectomy (LA) as an alternative to open appendectomy (OA) during early pregnancy, few studies have compared the effects of LA versus OA on the fetus and the outcome of the pregnancy. Twenty-eight consecutive females undergoing appendectomy for presumed appendicitis in the first two trimesters of pregnancy between January 2000 and December 2002 were identified retrospectively. Demographic information, weeks of pregnancy at operation, and surgical approach (LA or OA) were recorded. Study outcomes included operative and pregnancy-related complications, length of hospitalization, final outcome of pregnancy, and infant birth weight. Seventeen LA and 11 OA were performed. There were no significant differences in surgical or obstetrical complications, length of hospitalization, or birth weight between the two groups. Two cases of postoperative fetal demise were noted in the LA group. Although not statistically significant, the two fetal losses in the laparoscopic group are concerning. The current study did not demonstrate any advantages to the laparoscopic approach. Pending further investigation, the open approach may be preferred for appendectomy in pregnant patients during the first two trimesters of pregnancy.     

Long-term pulmonary function after lobectomy for congenital pulmonary airway malformation: is thoracoscopic approach really better than open?

Introduction

Congenital pulmonary airway malformation (CPAM) is the most common lung pathology diagnosed antenatally. Thoracoscopic lobectomy has shown increasing popularity, but the long-term result is still lacking. In this study we compared long -term pulmonary function after thoracoscopic and open lobectomy.

Chronic epididymitis: is epididymectomy a valid surgical treatment?

Chronic scrotal pain (≥3 months) is multi-factorial in nature and difficult to treat. Epididymectomy for chronic epididymal pain is rarely performed because of perceived poor outcome. We retrospectively audited our results, when published 'cure' following testicular denervation is 97%. The records of 32 males (35 consecutive epididymectomies) were retrospectively analysed. Thirteen had previous scrotal surgery. Eight (group one) had palpable painful epididymal abnormalities on clinical examination, nine (group two) had ultrasonic abnormalities but no palpable abnormality and 15 (group three) had neither. Pain response was recorded as: cured, improved, recurred or no change/worse. The mean time to operation was 23.83 months (2–121) and follow-up was 15.57 months (1–84). There were no significant aetiological differences between groups. In group one, 87.5% were cured with the remainder improved. Sixty-seven per cent of group two had a satisfactory outcome. Of group three, 20% were cured and a further 33% improved. Prior scrotal surgery, duration of symptoms and age were not predictive of outcome (Kruskal-Wallis) in terms of pain relief. Epididymectomy for structural abnormalities had excellent results. Those with chronic pain, normal examination and ultrasound had at best, a 55% chance of improvement. This group must be counselled about the low risk of success. The identification of the optimal surgical management of this difficult problem requires a multi-national registry study.     

Splenic vein aneurysm: is it a surgical indication?

Splenic vein aneurysms are rare and are usually caused by portal hypertension. Symptoms are unusual, but may include rupture or abdominal pain. Diagnosis can usually be made either by means of duplex ultrasonography or computed tomography scanning. Treatment varies from noninvasive follow-up to aneurysm excision. We report an expanding splenic vein aneurysm in a young woman with abdominal and back pain and no history of portal hypertension. She was treated with aneurysm excision and splenectomy.
