Minimal access aortic valve replacement: is it worth it?

Controversy surrounds the use of minimal access aortic valve replacement (AVR). This meta-analytical study quantified the effects of minimal access AVR on morbidity and mortality compared with conventional AVR and evaluated study heterogeneity and robustness of the findings using sensitivity analysis. Overall, meta-analysis suggested marginal benefits in perioperative mortality (4,667 patients; odds ratio, 0.72; 95% confidence interval, 0.51-1.00; p = 0.05), intensive care unit stay, total hospital stay, and ventilation time in the minimal access AVR group, although cross-clamp, cardiopulmonary bypass, and total operation times were longer. Study heterogeneity and apparent benefits in perioperative mortality were related to study quality, although results for intensive care unit and hospital stay were maintained according to the sensitivity analysis. This suggests that minimal access AVR can be offered on the basis of patient choice and cosmesis rather than evident clinical benefit.     

Liver surgery: what is feasible?

BACKGROUND: Bilobar hepatic metastases, a small residual liver volume, de-novo and recurrent lesions, simultaneous pulmonary metastases and infiltration of vascular structures are often limiting factors in the surgical treatment of primary and secondary liver tumors. Nevertheless surgery is the "gold standard" with the chance of long-term survival, not possible to achieve with locally ablation and chemotherapy. METHODS: The combination with neoadjuvant chemotherapy and radiofrequency ablation, extended liver resection after selective portal vein embolization, two-stage hepatectomy, resection and reconstruction of vascular structures in deep hypothermia and simultaneous resection of pulmonary metastases, increase the resectability even in patients with poor prognosis achieving 5-year-survival rates between 26-46 % in colorectal liver metastases, 40 % in primary liver tumors and a median survival of 42 months after resection of liver and lung metastases. CONCLUSION: Interdisciplinary treatment and aggressive surgical resection seem to be justified, when performed safely as a curative option.

Transanal endoscopic surgery with conventional laparoscopy materials: is it feasible?

Introduction

Transanal endoscopic surgery with conventional laparotomy materials may be an alternative to transanal endoscopic microsurgery (TEM) for the excision of rectal lesions susceptible to local resection.

Material and method

We prospectively analysed 27 patients included consecutively between 1999 and 2009, on whom a Transanal endoscopic operation (TEO) was performed by total resection of the rectal wall. All procedures were performed with a 40 mm rectoscope, initially designed by us and later with the Storz rectoscope, using conventional laparoscopic tools and material.

Results

We operated on 27 patients with a mean age of 69.4 years: 23 due to benign lesions and 4 malignant. The medium distance of the tumour to the anal margins was 8.2 cm (range 5-15) and a mean tumour diameter of 3.38 ± 1.2 cm. There were 4 postoperative complications, 3 due to bleeding and one case of perforation. The mean hospital stay was 6 ± 3.75 days. There was no perioperative mortality or recurrences..

Conclusion

Performing transanal endoscopic surgery with conventional laparoscopy material is feasible, with a reduction in costs and accessible to laparoscopy surgeons.     

Complex hepatobiliary surgery in the community setting: is it safe and feasible?

Background

Complex hepatobiliary surgical procedures for benign and malignant conditions are regularly performed at tertiary academic referral centers with excellent outcomes, but whether similar surgical outcomes are achievable in community hospitals is not well documented.

Methods

Eighty-four patients underwent complex hepatobiliary surgery between December 2004 and December 2008. Data were prospectively analyzed, including patient demographics, operative procedures, perioperative parameters, pathology, complications up to 30 days postoperatively, and long-term outcomes.

Results

The most frequent procedures performed were isolated segmentectomy or segmentectomies (n = 41 [49%]). Major hepatic resections (n = 32 [38%]) included 25 lobectomies (30%) and 7 trisegmentectomies (8%). Nine patients (11%) had surgical complications, and the most common indications for surgery was metastatic carcinoma (n = 42 [50%]).

Conclusions

Complex hepatobiliary surgery can be performed safely at a community-based teaching hospital with excellent outcomes. In the ongoing debate centering on mandatory referral and centralization of complex surgical procedures, tertiary community hospitals with well-determined outcomes should be included.     

Vascular reconstruction in Buerger's disease: is it feasible?

Purpose: Thromboangiitis obliterans (Buerger's disease) is a clinical syndrome characterized by segmental occlusions of the distal vessels. Although a cessation of using nicotine products usually helps, nevertheless a surgical revascularization may be needed in cases of stage III and IV limbs. Because of the distal and segmental nature of the disease, these procedures are rarely feasible. This article focuses on the feasibility of performing a vascular reconstruction in thromboangiitis obliterans. Methods: Thirty-six of 94 patients (38.3%) who were followed by the Peripheral Vascular Unit of Istanbul Medical Faculty were selected for revascularization and 27 of 36 (81%) patients underwent revascularization procedures. Results: During a 36-month follow-up, the patency rates at the 12th, 24th, and 36th months were 59.2%, 48%, and 33.3%, respectively. The limb salvage rate was 92.5%. Conclusions: Since patients affected by Buerger's disease consist a group of young population who are still in their productive stages, every effort should be taken to obtain a limb salvage in the ischemic period. Although the patency rates do not seem promising, the limb salvation rate was quite satisfactory. Received: October 29, 2001 / Accepted: July 2, 2002 Reprint requests to: Ş. Dilege     

“Near total” pneumonectomy: Is it feasible?

INTRODUCTIONThere are various procedures for treating lung cancer. Segmentectomy, wedge excision, lobectomy (including bilobectomy) and pneumonectomy are the operations used to resect malignant lung tumors. We describe an operation of near total pneumonectomy for the first time in the literature.PRESENTATION OF CASEA 55 year old man with borderline respiratory function was subjected to a right upper and middle lobectomy and stapled excision of the superior segment of the right lower lobe for a right upper lobe mass invading the major fissure.DISCUSSIONWhen operating on patients with borderline respiratory function one should always consider conservation of as much lung tissue as possible without compromising cancer clearance.CONCLUSIONFrom the case we present, it is obvious that the remaining lung basilar segments, combined with creation of an apical pleural tent, may well function properly and add benefit to the respiratory function of such compromised patients. We believe that this operation of near total pneumonectomy may have a role in lung cancer surgery.     

Laparoscopic revision of bariatric procedures: is it feasible?

Reoperative bariatric surgery is required in 10 per cent to 20 per cent of patients secondary to weight regain or complications of the previous procedure. This study evaluates the feasibility of performing the revision procedure laparoscopically. A retrospective review of all patients undergoing revision of a previous weight loss procedure between October 1998 and November 2003 was conducted. Demographics, indications for surgery, operative findings, and complications were reviewed. Thirty-nine revisions were performed in 37 patients. Indications for revision were failure to lose weight (22), gastric outlet stricture (10), refractory gastroesophageal reflux (GERD) (6), and blind loop syndrome (1). All 39 procedures were revised to Roux-en-Y gastric bypass (RYGBP), with 18 open revisions (OR) and 21 laparoscopic revisions (LR). Ten of the 21 LR (48%) were converted to an open procedure due to adhesions or unclear anatomy. Early complications requiring operation were noted in five procedures (two OR, three LR). Nine patients (seven OR, two LR) required surgery at least 3 months following their revision. One patient died (LR). The difference in body mass index (kg/m2) (BMI) pre- and post-op was 43.3+/-9.9 versus 37.4+/-9.2, P = 0.01 (follow-up 5 months), but no significant BMI differences between LR and OR patients were seen. Revisional bariatric surgery is associated with more complications requiring surgery early in the laparoscopic population versus more late complications in those approached open. Revisional bariatric surgery can be approached laparoscopically and with acceptable morbidity comparable to patients whose revision is approached open.     

Laparoscopic radical prostatectomy: is it feasible and reasonable?

Laparoscopic radical prostatectomy is an extremely challenging procedure for even experienced laparoscopic surgeons, and it is not practical to expect most urologists to learn the technique. Nevertheless, it is a feasible procedure and has short-term results comparable with conventional radical prostatectomy. For LRP to be an acceptable and reasonable alternative, the oncologic results must be equivalent to the results of RRP, and significant advantages is morbidity (hospital stay, pain, incontinence, impotence) must be attained; otherwise, the steep learning curve and the additional expense of the procedure make it difficult to justify as an alternative therapeutic modality. Beside a reduction in the transfusion rate, no other significant advantages of LRP over radical prostatectomy have been demonstrated definitively to date. As a result, the role of LRP in the management of prostate cancer remains investigational, and patients should be informed appropriately. The oncologic results and low morbidity of nerve-sparing RRP set a high standard for a laparoscopic technique to equal.     

Microsurgery in private practice: is it feasible economically?

Microsurgical free tissue transfer and replantations have long been the bailiwick of academic training centers and tertiary referral centers. However, the authors' experience with more than 350 consecutive free tissue transfers during a span of 15 years in a purely private setting illustrates the changing economics of the medical environment in that time frame. These data provide insight into the feasibility and practicality of maintaining a microsurgical practice outside an academic medical center.     

Zuckerkandl's tuberculum: could it be useful in thyroid surgery?

A thorough knowledge of thyroid anatomy could reduce the incidence of lesions to the inferior laryngeal nerve. In view of its relationship with the recurrent laryngeal nerve and the parathyroid gland, Zuckerkandl's tuberculum should be considered an anatomical landmark for the recurrent laryngeal nerve in thyroid surgery. The aim of the study was to verify whether the identification of Zuckerkandl's tuberculum could be useful to reduce the incidence of recurrent laryngeal nerve lesions. Four hundred and thirty-two patients underwent thyroid surgery over the period from January 2001 to December 2003 for benign (377 patients) or malignant disease (55 patients). Three-hundred and forty-eight (81%) underwent total thyroidectomy. Zuckerkandl's tuberculum was found in 74.5% of patients, with a high prevalence in the right lobe: in 5% of patients it was grade I, in 50% grade II and in 45% grade III. Its presence was associated with the recurrent laryngeal nerve in almost all cases. Eight of the patients undergoing total thyroidectomy suffered recurrent nerve paralysis, only 4 of which proved definitive. Identification of Zuckerkandl's tuberculum allows safer isolation of the recurrent laryngeal nerve and superior parathyroid gland dissection.
