Assessment of gastric pouch blood supply with indocyanine green fluorescence in conversional and revisional bariatric surgery: a prospective comparative study

Our study aimed to evaluate the usefulness of indocyanine green (ICG) angiography during conversional or revisional bariatric surgery. We prospectively enrolled all patients scheduled for reoperative bariatric surgery with gastric pouch resizing and ICG assessment and we compared them with a retrospective series of similar patients who did not receive ICG. The primary outcome was the rate of intraoperative change in the surgical strategy due to the ICG test. We included 32 prospective patients receiving intraoperatively an ICG perfusion test and 48 propensity score-matched controls. The mean age was 50.7 ± 9.7 years, 67 (83.7%) patients were female, and the mean BMI was 36.8 ± 5.3 kg/m2. The patient characteristics were similar in both groups. The ICG angiography was successfully conducted in all patients, and no change of the surgical strategy was necessary. Postoperative complications were similar in both groups (6.2% vs. 8.3%, p = 0.846), as well as operative time (125 ± 43 vs. 133 ± 47 min, p = 0.454) and length of hospital stay (2.8 ± 1.0 vs. 3.3 ± 2.2 days, p = 0.213). Our study suggested that ICG fluorescence angiography might not have been useful for assessing the blood supply of the gastric pouch in patients who underwent reoperative bariatric surgery. Therefore, it remains uncertain whether the application of this technique is indicated.

The Association of "U.S. News & World Report" Hospital Rankings and Outcomes Following Anterior Cervical Fusions: Do Rankings Even Matter?

STUDY DESIGN

Retrospective observational study.

OBJECTIVE

The aim of this study was to evaluate whether there are any differences in outcomes and costs for elective one- to three-level anterior cervical fusions (ACFs) performed at US News and World Report (USNWR) ranked and unranked hospitals.

SUMMARY OF BACKGROUND DATA

Although the USNWR rankings are advertised by media and are routinely used by patients as a guide in seeking care, evidence regarding whether these rankings are reflective of actual clinical outcome remains limited.

METHODS

The 2010-2014 USNWR hospital rankings were used to identify ranked hospitals in "Neurosurgery" and "Orthopedics." The 2010-2014 100% Medicare Standard Analytical Files (SAF100) were used to identify patients undergoing elective ACFs at ranked and unranked hospitals. Multivariable logistic regression and generalized linear regression analyses were used to assess for differences in 90-day outcomes and costs between ranked and unranked hospitals.

RESULTS

A total of 110,520 patients undergoing elective one- to three-level ACFs were included in the study, of which 10,289 (9.3%) underwent surgery in one of the 100 ranked hospitals. Following multivariate analysis, there were no significant differences between ranked versus unranked hospitals with regards to wound complications (1.2% vs. 1.1%; P = 0.907), cardiac complications (12.9% vs. 11.9%; P = 0.055), pulmonary complications (3.7% vs. 6.7%; P = 0.654), urinary tract infections (7.3% vs. 5.8%; P = 0.120), sepsis (9.3% vs. 7.9%; P = 0.847), deep venous thrombosis (1.9% vs. 1.3%; P = 0.077), revision surgery (0.3% vs. 0.3%; P = 0.617), and all-cause readmissions (4.7% vs. 4.4%; P = 0.266). Ranked hospitals, as compared to unranked hospitals, had a slightly lower odds of experiencing renal complications (7.0% vs. 4.9%; P = 0.047), but had significantly higher risk-adjusted 90-day charges (+$17,053; P < 0.001) and costs (+ $1695; P < 0.001).

CONCLUSION

Despite the higher charges and costs of care at ranked hospitals, these facilities appear to have similar outcomes as compared to unranked hospitals following elective ACFs.Level of Evidence: 3.

Patient-Reported Outcome Measures (Pain, Function, and Quality of Life) After Aseptic Revision Total Knee Arthroplasty

BACKGROUND

Despite the growing frequency of revision total knee arthroplasty (rTKA), there is limited information regarding patient-reported outcome measures (PROMs) after that procedure. Therefore, the purpose of this study was to determine (1) PROM improvements in pain, function, quality of life (QOL), and global health and (2) predictors of PROMs for patients undergoing aseptic rTKA as determined using a multilevel model with patients nested within surgeons.

METHODS

A prospective cohort of 246 patients who underwent aseptic rTKA from January 2016 to December 2017 and had baseline and 1-year postoperative PROMs were analyzed. The most common surgical indications were aseptic loosening (n = 109), instability (n = 73), and implant failure (n = 64). The PROMs included in this study were the Knee injury and Osteoarthritis Outcome Score (KOOS)-Pain, -Physical Function Short Form (PS), and -Quality of Life (QOL) as well as the Veterans Rand-12 (VR-12) Physical Component Summary (PCS) and Mental Component Summary (MCS). Multivariable linear regression models with patients nested within surgeons were constructed for predicting change in PROMs from baseline to 1 year.

RESULTS

The mean 1-year postoperative improvements in the KOOS-Pain and PS PROMs were 30.3 and 19.15 points, respectively, for the overall rTKA series. Improvement in the KOOS-Pain was associated with older age, baseline arthrofibrosis, lower baseline pain, and non-Medicare/Medicaid insurance and worsening of the scores was associated with multiple prior surgical procedures and instability. Improvement in the KOOS-PS was associated with baseline arthrofibrosis and female sex and worsening was associated with limited baseline function, an instability diagnosis, multiple prior surgical procedures, and increased hospital length of stay (LOS). Overall, the mean KOOS-QOL improved by 29.7 points. Although the mean VR-12 PCS improved, 54.9% of the patients saw no clinical improvement. Additionally, only 31.3% of the patients reported improvements in the VR-12 MCS. A multilevel mixed-effects model with patients/operations nested within surgeons demonstrated that the differences in the surgeons' results were minimal and explained only ∼1.86%, ∼1.12%, and ∼1.65% of the KOOS-Pain, KOOS-PS, and KOOS-QOL variance that was not explained by other predictors, respectively.

CONCLUSIONS

Overall, patients undergoing aseptic rTKA had improvements in pain, function, and QOL PROMs at 1 year. Although overall QOL improved, other global-health PROMs remained unchanged. The associations highlighted in this study can help guide the preoperative clinical decision-making process by setting expectations before aseptic rTKA.

Benchmarking Outcomes: Reoperation for Aortic Valve Patient-Prosthesis Mismatch

BACKGROUND

Surgical reoperations for symptomatic aortic valve patient-prosthesis mismatch (PPM) are complex. The purpose of this research was to investigate the clinical and echocardiographic outcomes of patients who underwent reoperation for correction of symptomatic PPM after prior aortic valve replacement.

METHODS

An institutional review identified 60 patients from 2004 to 2018 who underwent reoperative aortic valve replacement for PPM without structural valve degeneration. Univariate analyses were conducted to evaluate risk factors for perioperative mortality.

RESULTS

Median patient age was 62.8 (interquartile range, 48.3-68.7) years, and mean body mass index was 29.2 ± 6.6 kg/m2. Thirty-nine (66%) patients underwent a first-time reoperation, and 18 (30.5%) underwent a second-time reoperation. The median interval between initial operation to reoperation for the treatment of PPM was 89 months. Thirty-four (56.7%) patients underwent aortic root replacement, while the remainder (43.3%) underwent aortic valve replacement. Additional procedures included replacement of the ascending aorta with or without aortic arch in 26 (43.3%) patients and coronary artery bypass grafting in 7 (12%) patients. Operative mortality and the rates of stroke and renal failure were 5.0%, 3.3%, and 5.0%, respectively. Echocardiographic follow-up was available in 64.9% of patients at a mean follow-up of 36.5 months. Preoperative mean pressure gradients were 32.1 ± 16.0 mm Hg and mean aortic valve area was 0.8 ± 0.3 cm2, and both improved to 6.6 ± 4.2 mm Hg and 2.3 ± 0.7 cm2 (P < .001).

CONCLUSIONS

Reoperative surgery for PPM is complex but may be performed with good outcomes and low mortality in experienced centers. These data provide excellent clinical and hemodynamic benchmarks for the treatment of PPM in the current era of valve-in-valve transcatheter aortic valve replacement.

Exploring the views of female genital mutilation survivors, their male partners and healthcare professionals on the timing of deinfibulation surgery and NHS FGM care provision (the FGM Sister Study): protocol for a qualitative study

INTRODUCTION

Female genital mutilation (FGM) is a significant global health concern and is likely to become an increasingly important healthcare challenge in destination countries such as the UK owing to rising levels of migration from FGM-affected countries. Currently, there is no consensus on the optimal timing of deinfibulation (opening) surgery for women who have experienced type 3 FGM and care provision remains suboptimal in the UK. This qualitative study aims to explore the views of survivors, male partners and healthcare professionals (HCPs) on the timing of deinfibulation and delivery of NHS FGM services.

METHODS AND ANALYSIS

A qualitative study, informed by the Sound of Silence conceptual framework, will be undertaken via two work packages (WPs). WP1 will explore views on timing preferences for deinfibulation and NHS FGM services through interviews and discussion groups with FGM survivors (n~50), male partners (n~10) and HCPs (n~50). WP2 will use established techniques via two workshops (community (n~20-25 participants) and national stakeholder (n~30-35 participants)) to synthesise qualitative research findings and inform best practice and policy recommendations around the timing of deinfibulation and NHS FGM care provision. Supported by trained interpreters, data collection will be audio recorded and transcribed. Data will be analysed using the framework method to facilitate a systematic mapping and exploration of qualitative data from multiple sources.

ETHICS AND DISSEMINATION

The study has received ethical approval from the North West Greater Manchester East Research Ethics Committee (18/NW/0498). The outputs for this study will be recommendations for best practice and policy around FGM care provision that reflects the views and preferences of key stakeholders. The findings will be disseminated via conference presentations, peer-reviewed publications, patient groups, third sector organisations and social media.

Bundled Payment "Creep": Institutional Redesign for Primary Arthroplasty Positively Affects Revision Arthroplasty

BACKGROUND

Revision total joint arthroplasty (TJA) is associated with increased readmissions, complications, and expense compared to primary TJA. Bundled payment methods have been used to improve value of care in primary TJA, but little is known of their impact in revision TJA patients. The purpose of this study is to evaluate the impact of a care redesign for a bundled payment model for primary TJA on quality metrics for revision patients, despite absence of a targeted intervention for revisions.

METHODS

We compared quality metrics for all revision TJA patients including readmission rate, use of post-acute care facility after discharge, length of stay, and cost, between the year leading up to the redesign and the 2 years following its implementation. Changes in the primary TJA group over the same time period were also assessed for comparison.

RESULTS

Despite a volume increase of 37% over the study period, readmissions declined from 8.9% to 5.8%. Use of post-acute care facilities decreased from 42% to 24%. Length of stay went from 4.84 to 3.92 days. Cost of the hospital episode declined by 5%.

CONCLUSION

Our health system experienced a halo effect from our bundled payment-influenced care redesign, with revision TJA patients experiencing notable improvements in several quality metrics, though not as pronounced as in the primary TJA population. These changes benefitted the patients, the health system, and the payers. We attribute these positive changes to an altered institutional mindset, resulting from an invested and aligned care team, with active physician oversight over the care episode.

Comparison of the clinical outcomes of revision of failed UKAs to TKAs with primary TKAs: A systematic review and meta-analysis

Unicompartmental knee arthroplasty (UKA) is one of the effective surgical methods for the treatment of unicompartmental knee arthritis. When UKA fails, a revised surgery to total knee arthroplasty (TKA) is often necessary. The purpose of this study was to compare the clinical outcomes of revision of failed UKAs to TKAs with primary TKAs. The hypothesis was that the TKAs revised from UKAs had inferior clinical outcomes compared with primary TKAs.This meta-analysis was conducted in accordance with the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guidelines. Newcastle-Ottawa Scale (NOS) proposed by the Cochrane Collaboration was used for evaluating the methodological quality of the studies. PubMed, Medline, Embase, Web of Science, and the Cochrane Library were searched to identify studies that compared the revision of UKA to TKA with primary TKA. Primary outcomes included Range of motion (ROM); Knee society score (KSS); (re-)revision rate and complications. Secondary outcomes were blood loss and length of hospital stay.A total of 8 eligible retrospective comparative studies were identified from a keyword search. Results revealed that the primary TKAs group has a better ROM (MD = -7.29, 95% CI:-14.03-0.56, P < .05), higher Knee Society Knee scores (MD = -0.54, 95% CI:-1.12-0.04, P < .05), higher Knee Society function score (MD = -0.65,95% CI:-1.25-0.06, P < .05), lower (re-)revision rate (MD = 4.15, 95% CI:2.37-7.25, P < .05) than rUKAs. There was no significant difference in postoperative complications, blood loss and length of stay between the 2 groups.Our meta-analysis revealed that compared with primary TKAs, TKAs revised from UKAs had inferior clinical outcomes.

Open Surgical Incisions After Colorectal Surgery Improve Quality Metrics, But Do Patients Benefit?

BACKGROUND

Surgical site infection is a frequent cause of morbidity after colorectal resection and is a quality measure for hospitals and surgeons. In an effort to reduce the risk of postoperative infections, many wounds are left open at the time of surgery for secondary or delayed primary wound closure.

OBJECTIVE

The purpose of this study was to evaluate the impact of delayed wound closure on the rate of surgical infections and resource use.

DESIGN

This retrospective propensity-matched study compared colorectal surgery patients with wounds left open with a cohort of patients with primary skin closure.

SETTINGS

The American College of Surgeons National Quality Improvement Program Participant Use file for 2014 was queried.

PATIENTS

A total of 50,212 patients who underwent elective or emergent colectomy, proctectomy, and stoma creation were included.

MAIN OUTCOME MEASURES

Rates of postoperative infections and discharge to medical facilities were measured.

RESULTS

Surgical wounds were left open in 2.9% of colorectal cases (n = 1466). Patients with skin left open were broadly higher risk, as evidenced by a significantly higher median estimated probability of 30-day mortality (3.40% vs 0.45%; p < 0.0001). After propensity matching (n = 1382 per group), there were no significant differences between baseline characteristics. Within the matched cohort, there were no differences in the rates of 30-day mortality, deep or organ space infection, or sepsis (all p > 0.05). Resource use was higher for patients with incisions left open, including longer length of stay (11 vs 10 d; p = 0.006) and higher rates of discharge to a facility (34% vs 27%; p < 0.001).

LIMITATIONS

This study was limited by its retrospective design and a large data set with a bias toward academic institutions.

CONCLUSIONS

In a well-matched colorectal cohort, secondary or delayed wound closure eliminates superficial surgical infections, but there was no decrease in deep or organ space infections. In addition, attention should be given to the possibility for increased resource use associated with open surgical incisions. See Video Abstract at http://links.lww.com/DCR/A560.

[Strategies for prevention and treatment of postoperative complications of gastric cancer]

Postoperative complications after gastric cancer surgery has their own specificity and complexity, and the strategies for prevention and treatment should be of equal emphasis on both theory and technology. Based on the knowledge and familiarity with different postoperative complications, to efficiently prevent them, it is not only necessary to strengthen the training of acknowledged operative strategy, smooth and precise surgical techniques, but also to address the importance of overall preoperative assessment for patients, to treat the basic diseases, and to improve and correct their general conditions. Combining with the concept and basic protocol of enhanced recovery after surgery (ERAS), it is preferred to work out an individualized perioperative preventing strategy for patients who have high risk factors of specific postoperative complications. After the operation, to guarantee intensive and individual managements for patients, to catch early abnormal signs, then to make early and precise diagnosis, and to do timely response and accurate treatments, including timely and proper re-operations, can improve the efficacy of complications and promote the recovery of patients as soon as possible.

A Cross-sectional Study to Determine Whether Adjustment to an Ostomy Can Predict Health-related and/or Overall Quality of Life

Ostomy-specific adjustment may or may not predict health-related quality of life (HRQoL) and/or overall quality of life (QoL). A cross-sectional study was conducted among patients recruited from the customer registers of 8 surgical suppliers and pharmacies across Norway between November 2010 and March 2011 to determine which of the 34 items of the Ostomy Adjustment Scale (OAS) are the strongest predictors for HRQoL and overall QoL and to determine the HRQoL and overall QoL of individuals with an ostomy compared to a control group representing the general population. Persons who were >18 years old; had a permanent colostomy, ileostomy, or urostomy for >3 months; and could read and write Norwegian were invited to participate. The participants received information about the study in a letter from the researcher and returned their demographic information (addressing gender, age, marital status, education, diagnosis, time since surgery, and ostomy type) and study questionnaires using prepaid envelopes. The 158 participants (mean age 64 years [range 29-91], 89 [56%] men and 69 [44%] women) completed and returned by mail a sociodemographic questionnaire, the 34-item OAS (questions scored on a scale of 1 to 6, totally disagree to totally agree, score range 34 to 204), the Short Form-36 (SF-36, including 2 main components [physical and mental issues] divided into 8 subscales, scored from 0 to 100), and the 16-item Quality of Life Scale (QOLS) instrument (each response scored 1 to 7, from very dissatisfied to very satisfied; total score ranging from 16 to 112). Statistical analysis, including ordinary least square regression analyses, assessed whether the OAS independently predicted the sum scores of the SF-36 (physical component summary [PCS] and mental component summary [MCS]) and the QOLS score after adjusting for age, gender, marital status, education, diagnosis, time since surgery, and ostomy type. The OAS significantly predicted the SF-36 (PCS and MCS) and QOLS scores (P <0.001). Five (5) OAS items ("living a fulfilling life," "being free to travel where I want despite my ostomy," "realizing that this ostomy will be there forever," "worries about being left alone," and "embarrassing accidents in sexual activities") strongly predicted the composite score of the SF-36 (PCS and MCS) and QOLS measurements. The SF-36 scores in physical role functioning, general health, vitality, and MCS were lower in ostomy patients than controls (P < 0.05), whereas no difference was found for QOLS. Overall, ostomy-specific adjustment may be an important predictor of HRQoL and overall QoL, with the OAS factors described above having greater influence. More research such as prospective cohort studies are needed regarding patient adjustment to an ostomy.

Setting benchmark revision rates for total hip replacement: analysis of registry evidence

OBJECTIVE

To compare 10 year revision rates for frequently used types of primary total hip replacement to inform setting of a new benchmark rate in England and Wales that will be of international relevance.

DESIGN

Retrospective cohort study.

SETTING

National Joint Registry.

PARTICIPANTS

239 000 patient records.

MAIN OUTCOME MEASURES

Revision rates for five frequently used types of total hip replacement that differed according to bearing surface and fixation mode, encompassing 62% of all primary total hip replacements in the National Joint Registry for England and Wales. Revision rates were compared using Kaplan-Meier and competing risks analyses, and five and 10 year rates were estimated using well fitting parametric models.

RESULTS

Estimated revision rates at 10 years were 4% or below for four of the five types of total hip replacement investigated. Rates differed little according to Kaplan-Meier or competing risks analysis, but differences between prosthesis types were more substantial. Cemented prostheses with ceramic-on-polyethylene bearing surfaces had the lowest revision rates (1.88-2.11% at 10 years depending on the method used), and cementless prostheses with ceramic-on-ceramic bearing surfaces had the highest revision rates (3.93-4.33%). Men were more likely to receive revision of total hip replacement than were women, and this difference was statistically significant for four of the five prosthesis types.

CONCLUSIONS

Ten year revision rate estimates were all less than 5%, and in some instances considerably less. The results suggest that the current revision rate benchmark should be at least halved from 10% to less than 5% at 10 years. This has implications for benchmarks internationally.

Early and late outcomes after cardiac retransplantation

BACKGROUND

Cardiac retransplantation remains the most viable option for patients with allograft heart failure; however, careful patient selection is paramount considering limited allograft resources. We analyzed clinical outcomes following retransplantation in an academic, tertiary care institution.

METHODS

Between 1981 and 2011, 593 heart transplantations, including 22 retransplantations were performed at our institution. We analyzed the preoperative demographic characteristics, cause of allograft loss, short- and long-term surgical outcomes and cause of death among patients who had cardiac retransplantations.

RESULTS

Twenty-two patients underwent retransplantation: 10 for graft vascular disease, 7 for acute rejection and 5 for primary graft failure. Mean age at retransplantation was 43 (standard deviation [SD] 15) years; 6 patients were women. Thirteen patients were critically ill preoperatively, requiring inotropes and/or mechanical support. The median interval between primary and retransplantation was 2.2 (range 0-16) years. Thirty-day mortality was 31.8%, and conditional (> 30 d) 1-, 5- and 10-year survival after retransplantation were 93%, 79% and 59%, respectively. A diagnosis of allograft vasculopathy (p = 0.008) and an interval between primary and retransplantation greater than 1 year (p = 0.016) had a significantly favourable impact on 30-day mortality. The median and mean survival after retransplantation were 3.3 and 5 (SD 6, range 0-18) years, respectively; graft vascular disease and multiorgan failure were the most common causes of death.

CONCLUSION

Long-term outcomes for primary and retransplantation are similar if patients survive the 30-day postoperative period. Retransplantation within 1 year of the primary transplantation resulted in a high perioperative mortality and thus may be a contraindication to retransplantation.

Renal transplantation in patients with atypical haemolytic uraemic syndrome: a tailor made approach is necessary

A 33-year-old woman with a history of chronic transplant dysfunction because of repeated bouts of haemolytic uraemic syndrome (HUS) was considered for a second transplant. Extensive genetic investigation of the complement system was executed to rule out known mutations prone to development of HUS. This case illustrates the importance of genetic screening in patients with recurrent HUS.

Fusiform aneurysms of the vertebrobasilar arterial trunk: choice of endovascular methods and therapeutic efficacy

BACKGROUND

Fusiform aneurysms (FUANs) of vertebrobasilar arterial (VBA) trunk are difficult to treat by using current surgical and endovascular techniques. The objective of this study is to compare the efficacy of FUANs of VBA trunk which was treated with various therapeutic modalities including unilateral or bilateral vertebral artery occlusion, trapping of the aneurysm with coils, stent-assistant coiling, or sole stenting.

METHODS

Between 2000 and 2008, 17 patients with FUANs (ranged in size from 8 to 45 mm) of VBA trunk in our hospital underwent endovascular treatment in our hospital. Eleven patients were evaluated by test occlusion with nondetachable silicone balloon or hyperglide balloon, and seven patients in this series passed testing with temporary balloon occlusion, among which four patients showed positive result, and three patients were conducted bilateral VA test occlusion. Finally, nine patients underwent a trapping of the aneurysm by coils, four patients were treated with stent-supported coil embolization, and four patients with nonhemorrhagic FUAN of VBA were treated only by stenting.

RESULTS

The average imaging follow-up was 28 months, with a range from 6 to 48 months. Fourteen (82%) had excellent or good outcome, three (17.6%) had a poor outcome, and one (5.8%) died.

CONCLUSIONS

Management of FUANs of VBA trunk often poses difficult therapeutic problems. In some cases, multiple treatment sessions may be not only safe but also necessary for the effective treatment of these aneurysms to achieve a complete or an acceptable result.

Safety and short-term outcomes of laparoscopic sleeve gastrectomy as a revisional approach for failed laparoscopic adjustable gastric banding in the treatment of morbid obesity

Laparoscopic sleeve gastrectomy (LSG) has been used as a first step of a two-stage approach in bariatric surgery for high-risk patients. Recently, LSG is being utilized as a primary and final procedure for morbid obesity with acceptable short-term results. The aim of this study is to investigate the effectiveness of LSG as a revisional procedure for patients with unsatisfactory outcomes after laparoscopic adjustable gastric band (LAGB). A retrospective review of a prospectively maintained database was performed. Data were reviewed for all patients undergoing revision from LAGB to LSG during the period May 2005 and May 2009. Data collected included demographics, indication for revision, operative time, length of stay, postoperative complications, and degree of weight reduction. Fifteen patients (three males and 12 females) had revisional surgery converting a LAGB to a LSG. The indication in four patients (26.66%) was weight regains and in five patients (33.33%) was poor weight loss; four patients (26.66%) had a band slippage and symptoms of gastroesophageal reflux, and one patient (6.66%) had poor weight loss, band slippage, and reflux. In one patient (6.66%), the indication was slippage and duodenal fistula. One-step revision procedure was done in 13 patients (86.66%), while two-step procedure was done in two patients (13.33%). Mean preoperative weight and BMI were 233.02 (181.4-300) lb and 38.66 (29.7-49.3) kg/m2, respectively. Mean weight loss at 2, 6, 12, 18, and 24 months postoperatively was 20.7, 48.3, 57.2, 60.1, and 13.5 lb, respectively. Mean % excess BMI loss was 28.9%, 64.2%, 65.3%, 65.7%, and 22.25% at 2, 6, 12, 18, and 24 months, respectively. There was one major complication (staple line leak) and one postoperative acute gastric outlet obstruction. We had no mortality. Thirteen patients were followed up postoperatively. The number decreased as follow-up time progressed. LSG could provide short-term weight loss after previously failed LABG, but prone to more complications compared to an initial LSG without a prior bariatric procedure.

Revision total hip arthroplasty for ceramic head fracture: a long-term follow-up

The results of revision total hip arthroplasty (THA) for ceramic head fracture have generally been disappointing, largely due to third body wear after incomplete synovectomy. We have followed 8 patients who sustained ceramic head fractures and were subsequently revised to a metal-on-polyethylene articulation. There were no revisions for osteolysis or aseptic loosening at a mean follow-up of 10.5 years. The yearly wear rates of each of 5 of these THAs after revision were compared with 6 matched metal-on-polyethylene THAs; there were no significant differences in wear rates. Greater than 10-year survivorship with a metal-on-polyethylene bearing couple is possible after revision THA for a ceramic head fracture if a complete and thorough synovectomy can be performed. Our technique of synovectomy will be described.

The effect of ACGME duty hour restrictions on operative continuity of care

Resident work restrictions limit participation in operations that address problems created by a prior operation, because complications occur at any time. We compared resident and attending surgeon staffing of operative complications. We reviewed all complications that required a second operation reported at our Morbidity and Mortality Conference over 1 year, noting surgeons present, their postgraduate year level, and call shift. Comparisons were done using chi2. Of 142 cases, 39 involved a second operation. The same attending surgeon was present for both in 79 per cent of cases, whereas the same resident was present in only 44 per cent (P = 0.002). Postgraduate year 4 to 5 were less likely to be present for second operations than attendings (48% vs 87%, P = 0.011). Resident shift (day, night float, and weekend) was known in 32 cases. When the first operation occurred during day hours, attendings and residents were equally likely to be present at the second (55% and 45%, P = 0.16). When original operations took place during night float or weekend shifts, residents were less likely to be present (33%) than attendings (83%) at second operations (P = 0.036). Duty hour restrictions interfere with operative continuity of care. Reoperations should be exempted from duty hour restrictions.

[Stump appendicitis after previous appendicectomy]

Two patients, a 25-year-old male and a 57-year-old female, were treated for stump appendicitis. Both patients had undergone appendicectomy 6 months previously and again presented with pain in the right lower abdominal region. On physical examination, the first patient had tenderness as well as rebound tenderness over the entire abdomen, indicative of a general peritonitis. The second patient had tenderness and rebound tenderness in the right iliac fossa alone. Both patients underwent a laparotomy. In the first patient a perforated appendiceal stump was found and removed. In the second patient an acutely inflamed appendiceal stump was found and removed. Appendicitis of a residual appendiceal stump following incomplete appendicectomy is a rare cause of abdominal pain. A lack of familiarity with this condition frequently causes a delay in diagnosis, which increases the chance of perforation and intra-abdominal sepsis. Therefore, all clinicians need to be aware of the possibility of stump appendicitis and to take appropriate measures to prevent serious complications should they suspect this.

Tertiary resurfacing after one of the first free flaps in Europe, a reflection on 30 years of microsurgical progress

Free flaps have been used for over 30 years. During this period, improved anatomical understanding has increased donor options and available pedicle lengths, permitting safer, single-stage reconstructions with simpler anastomoses. Refinements, such as perforator flaps in particular, have greatly improved donor morbidity, recipient site cosmesis, and the ability to replace 'like with like' while retaining options for innervation. This case highlights the evolution from one of Europe's first free tissue transfers, effectively a perforator flap, through the advent of free muscle flaps to the current generation of contourable perforator flaps. Free flap transfer has become increasingly sophisticated, safer, and more predictable, yet the potential quality of reconstructive outcome has changed little.

Comparison of on-demand vs planned relaparotomy strategy in patients with severe peritonitis: a randomized trial

CONTEXT

In patients with severe secondary peritonitis, there are 2 surgical treatment strategies following an initial emergency laparotomy: planned relaparotomy and relaparotomy only when the patient's condition demands it ("on-demand"). The on-demand strategy may reduce mortality, morbidity, health care utilization, and costs. However, randomized trials have not been performed.

OBJECTIVE

To compare patient outcome, health care utilization, and costs of on-demand and planned relaparotomy.

DESIGN, SETTING, AND PATIENTS

Randomized, nonblinded clinical trial at 2 academic and 5 regional teaching hospitals in the Netherlands from November 2001 through February 2005. Patients had severe secondary peritonitis and an Acute Physiology and Chronic Health Evaluation (APACHE-II) score of 11 or greater.

INTERVENTION

Random allocation to on-demand or planned relaparotomy strategy.

MAIN OUTCOME MEASURES

The primary end point was death and/or peritonitis-related morbidity within a 12-month follow-up period. Secondary end points included health care utilization and costs.

RESULTS

A total of 232 patients (116 on-demand and 116 planned) were randomized. One patient in the on-demand group was excluded due to an operative diagnosis of pancreatitis and 3 in each group withdrew or were lost to follow-up. There was no significant difference in primary end point (57% on-demand [n = 64] vs 65% planned [n = 73]; P = .25) or in mortality alone (29% on-demand [n = 32] vs 36% planned [n = 41]; P = .22) or morbidity alone (40% on-demand [n = 32] vs 44% planned [n = 32]; P = .58). A total of 42% of the on-demand patients had a relaparotomy vs 94% of the planned relaparotomy group. A total of 31% of first relaparotomies were negative in the on-demand group vs 66% in the planned group (P <.001). Patients in the on-demand group had shorter median intensive care unit stays (7 vs 11 days; P = .001) and shorter median hospital stays (27 vs 35 days; P = .008). Direct medical costs per patient were reduced by 23% using the on-demand strategy.

CONCLUSION

Patients in the on-demand relaparotomy group did not have a significantly lower rate of death or major peritonitis-related morbidity compared with the planned relaparotomy group but did have a substantial reduction in relaparotomies, health care utilization, and medical costs.

Early combined cranioplasty and programmable shunt in patients with skull bone defects and CSF-circulation disorders

OBJECTIVE

This study assesses the clinical outcome after early combined cranioplasty (own frozen bone) and shunt implantation (Codman-Medos programmable VP shunt) in patients with skull bone defects and cerebrospinal fluid (CSF) circulation disorders.

METHOD

Medical records were reviewed retrospectively for the last 100 patients with CSF disorders after trauma or subarachnoid hemorrhage (SAH), who previously underwent decompressive craniotomy owing to therapy-resistant brain swelling. Patients treated with early (5 to 7 weeks after injury) combined cranioplasty and shunt implantation were analysed and a follow-up for the survivors was obtained.

RESULTS

In 60 patients with a daily CSF external drainage over 150 ml and dilated ventricles in CT scan, a programmable VP shunt was implanted simultaneously with the cranioplasty within 5.1 weeks after decompression. The neurological condition 6 months later was good (independent patients) in 39 cases (65%); 12 patients (20%) survived with a severe disability; three patients (5%) remained in a persistent vegetative state and only six patients (10%) died. There were few complications: bone or shunt infection (three cases), post-operative intracranial bleeding (one case), transitory neurological impairment after bone reimplantation (two cases), bone resorption (two cases) and shunt dysfunction (three cases).

CONCLUSION

The early reimplantation of the patient's own skull bone combined to the employment of a programmable shunt system allowed us a dynamic adjustment of the intracranial pressure (ICP) changes. The combined treatment reduced the number of required surgical procedures, complications and unsatisfactory patient outcomes.

Non-compliance with the re-excision guidelines for cutaneous melanoma in The Netherlands does not influence survival

AIM

To evaluate causes and consequences of not adhering to the clinical practice guideline for cutaneous malignant melanoma.

METHODS

We conducted a retrospective cohort study of the clinical records of 454 subjects whose pathological reports were obtained from a population-based cancer registry to assess determinants and effects of non-compliance of physicians with the excision policy and the related clinical practice guideline for patients with primary localized cutaneous malignant melanoma (CMM). A comparative analysis was performed of patients who did and did not undergo re-excision (compliance versus non-compliance with the guideline). Subjects diagnosed in 1988, 1993 and 1997, just 1 year after publication of the (adapted) guideline, were followed until death due to any cause or until July 1st 2003.

RESULTS

Old age was the most important determinant of non-compliance. After adjusting for age at diagnosis, gender, subsite and Breslow thickness there was no significant difference in overall survival between the compliance group and the non-compliance group.

CONCLUSIONS

Non-compliance to the guideline is more common in older patients and in patients with melanoma in the head and neck region. After adjusting for confounders, a significant effect of complying with the guidelines on overall survival could not be observed.

Optimally invasive exposure in revision total hip arthroplasty: a guide to selection and technique

Revision total hip arthroplasty requires a careful surgical plan. Selection of the appropriate exposure is an essential step for success. Exposure is important not only for the complete and safe visualization and extraction of components and cement, but also for the achievement of a stable construct at the end of the procedure. In addition, controlled exposure minimizes intraoperative complications and bone and soft-tissue damage, essential considerations for eradication of infection. Three questions need to be addressed at the preoperative stage: (1) Is this a straightforward revision that can be handled with a standard approach? (2) Is this a more complex revision requiring an extensile exposure? (3) Is this an unusual revision requiring special techniques to allow adequate access that cannot be obtained using standard extensile techniques? Each group of exposures presents three further possibilities, each of which has specific indications, advantages, and disadvantages. In conjunction with the preoperative analysis, this knowledge should enable the revision surgeon to select the most appropriate approach, resulting in optimal exposure for each individual revision scenario.

Clinical review: the strategy of immediate reoperation for transsphenoidal surgery for Cushing's disease

CONTEXT

Transsphenoidal surgery is currently the primary therapeutic option for Cushing's disease. Despite considerable initial success, 10-30% of patients fail to achieve lasting remission.

EVIDENCE ACQUISITION

We evaluated a strategy of immediate reoperation in surgical failures judged by plasma cortisol levels that did not fall to 2 microg/dl or less within 72 h of surgery. Of 215 patients with presumed ACTH microadenomas, treated between 1993 and 2004, 12 met inclusion criteria and had prompt (within 15 d) reoperation for residual or missed ACTH microadenoma. These 12 patients represent 28% of those who did not have evidence of postoperative adrenal insufficiency.

EVIDENCE SYNTHESIS

Based on an outcome measure of sustained subnormal or normal plasma cortisol levels, eight of 12 patients (67%) achieved remission from the two operations. Adjunctive therapies (radiotherapy, gamma knife radiosurgery, and adrenalectomy) led to remission in another three patients. It is recognized that this outcome required either total hypophysectomy (one patient) or postoperative hypopituitarism (all patients in remission).

CONCLUSION

Magnetic resonance imaging was not usually helpful in determining therapeutic strategies; however, inferior petrosal sinus sampling was critical in providing confidence that the disease was of pituitary origin. A treatment algorithm is recommended, based on this study.

Kyphoplasty for salvage of a failed vertebroplasty in osteoporotic vertebral compression fractures: case report and surgical technique

Osteoporotic vertebral compression fractures are a significant source of morbidity. Recently described techniques of vertebroplasty and kyphoplasty have provided consistent successful outcomes in the short term. However, techniques to address the failure of vertebroplasty have not been addressed. We present two cases of failed vertebroplasty that were revised with a kyphoplasty technique. Both patients had near complete resolution of preoperative symptoms and had a significant vertebral height restoration more than 10 months after revision with kyphoplasty. In conclusion, kyphoplasty technique can be utilized to salvage failed vertebroplasty.

Retinopathy of prematurity: involution, factors predisposing to retinal detachment, and expected utility of preemptive surgical reintervention

PURPOSE

To characterize involution of retinopathy of prematurity (ROP) following treatment at threshold, to identify findings during involution that portend development of retinal detachment, and to assess the potential utility of preemptive vitrectomy for eyes with high-risk features.

METHODS

The probability of ROP involution and of retinal detachment evolution over time was analyzed in 262 treated eyes of 138 infants in a retrospective observational non-case controlled series. Expected utility of preemptive reintervention in eyes with high-risk features was evaluated using decision analysis. Modifications were devised to enhance classification of advanced ROP.

RESULTS

ROP fully involuted in approximately 80% of eyes within 28 days of treatment. Vitreous organization meeting the study's clinically important definition was associated with a 31-fold (5.37 to 183.63; P < .0001) and a 13-fold (2.97 to 58.59; P < .0001) increase in the odds for retinal detachment for right and left eyes, respectively. Vitreous hemorrhage defined as clinically important was associated with a 38-fold (2.69 to 551.19; P = .007) and a 15-fold (1.65 to 144.12; P = .02) increase in the odds for retinal detachment for right and left eyes, respectively. As modeled, an expected utility of 0.85 was calculated for preemptive vitrectomy compared with 0.79 for deferred vitrectomy for eyes with clinically important vitreous organization.

CONCLUSIONS

Acute-phase ROP involuted quickly in most eyes. Vitreous organization and vitreous hemorrhage were predictive of eyes that developed a retinal detachment. Decision analysis suggests that preemptive vitrectomy for eyes with vitreous organization meeting specific criteria is not likely to be worse than deferred vitrectomy, and it could be advantageous in some scenarios.

Effectiveness of percutaneous mechanical mitral commissurotomy using the metallic commissurotome in patients with restenosis after balloon or previous surgical commissurotomy

Balloon mitral valvuloplasty has been reported to give equal or less positive results after previous commissurotomy than after a first procedure. Percutaneous mechanical mitral commissurotomy (PMMC) is a new technique that has not yet been evaluated in this subset of patients. Of 1,175 PMMC procedures (1,175 patients), 173 patients (14.7%) had previous commissurotomy; patients were older (40 vs 35 years of age, p <0.0001) and more often in atrial fibrillation (34% vs 21%, p = 0.0016) than were patients who had not undergone previous commissurotomy. The baseline transmitral gradient was lower (17 +/- 8 vs 19 +/- 8 mm Hg, p <0.002) and the echocardiographic Wilkins score was higher (8.7 +/- 1.9 vs 7.6 +/- 1.8, p <0.0001) for patients who underwent previous commissurotomy. Baseline mitral valve area was comparable between the 2 groups (0.96 +/- 0.21 vs 0.93 +/- 0.24 cm(2)). Immediate results were satisfactory, although slightly less favorable after previous commissurotomy, with a final mitral valve area of 2.01 +/- 0.30 versus 2.12 +/- 0.36 cm(2) (p <0.0001), and a residual transvalvular gradient of 5.0 +/- 3.6 versus 4.2 +/- 4.1 mm Hg (p = 0.003). The rates of procedural success (93%) and severe complications (4.7%) were comparable between the 2 groups. Thus, PMMC is an effective and safe technique for the treatment of mitral restenosis after previous commissurotomy.

Decision for retransplantation of the liver: an experience- and cost-based analysis

OBJECTIVE

To determine the patient factors affecting patient outcome of first liver retransplantation at a single center to help in the decision process for retransplantation.

SUMMARY BACKGROUND DATA

Given the critical organ shortage, one of the most controversial questions is whether hepatic retransplantation, the only chance of survival for patients with a failing first organ, should be offered liberally despite its greater cost, worse survival, and the inevitable denial of access to primary transplantation to other patients due to the depletion of an already-limited organ supply. The authors' experience of 139 consecutive retransplantations was reviewed to evaluate the results of retransplantation and to identify the factors that could improve the results.

METHODS

From 1986 to 2000, 1,038 patients underwent only one liver transplant and 139 patients underwent a first retransplant at the authors' center (first retransplantation rate = 12%). Multivariate analysis was performed to identify variables, excluding intraoperative and donor variables, associated with graft and patient long-term survival following first retransplantation. Lengths of hospital and intensive care unit stay and hospital charges incurred during the transplantation admissions were compared for retransplanted patients and primary-transplant patients.

RESULTS

One-year, 5-year, and 10-year graft and patient survival rates following retransplantation were 54.0%, 42.5%, 36.8% and 61.2%, 53.7%, and 50.1%, respectively. These percentages were significantly less than those following a single hepatic transplantation at the authors' center during the same period (82.3%, 72.1%, and 66.9%, respectively). On multivariate analysis, three patient variables were significantly associated with a poorer patient outcome: urgency of retransplantation (excluding primary nonfunction), age, and creatinine. Primary nonfunction as an indication for retransplantation, total bilirubin, and factor II level were associated with a better prognosis. The final model was highly predictive of survival: according to the combination of the factors affecting outcome, 5-year patient survival rates varied from 15% to 83%. Retransplant patients had significantly longer hospital and intensive care unit stays and accumulated significantly higher total hospital charges than those receiving only one transplant. CONCLUSIONS These data confirm the utility of retransplantation in the elective situation. In the emergency setting, retransplantation should be used with discretion, and it should be avoided in subgroups of patients with little chance of success.

A lack of consensus in the assessment of fracture healing among orthopaedic surgeons

BACKGROUND

The assessment of fracture healing is both a clinically relevant and frequently used outcome measure following lower extremity trauma. However, it remains uncertain whether there is a consensus in the assessment of fracture healing among orthopaedic surgeons. Variability in the assessment of healing may have important implications in surgeons' decisions to intervene when they perceive fracture healing is slow to progress.

OBJECTIVE

To identify surgeons' approaches in the assessment of tibial fracture healing and the definitions of a delayed union, nonunion, and malunion among orthopaedic surgeons.

STUDY DESIGN

Cross-sectional survey of 577 orthopaedic surgeons.

METHODS

Focus groups, key informants, and sampling to redundancy strategies were used to develop a survey to examine surgeons' opinions in the assessment of tibial shaft fractures. Surgeons were asked how often the following variables were used in the assessment of fracture healing: (a) callus size; (b) cortical continuity; (c) progressive loss of fracture line; (d) pain with weight bearing; and (e) pain to palpation at the fracture site. Further, surgeons were asked to provide a time point beyond which a delayed union becomes a nonunion. Finally, surgeons specified their limits of acceptable fracture alignment (translation, shortening, rotation, varus/valgus, and procurvatum/recurvatum). The survey was pilot tested for clarity and content validity. This survey was mailed to 577 orthopaedic surgeons who were members of the Orthopaedic Trauma Association, American Academy of Orthopaedic Surgeons, and European-AO International-affiliated trauma centers.

RESULTS

Responses were obtained from 444 surgeons (response rate 77%). For each variable, the proportion of surgeons who always used the criterion ranged from 39.7% to 45.4%, and those who occasionally or never used the criterion ranged from 20.7% to 26.9%. Surgeons' definitions of delayed union ranged from 1 to 8 months, whereas definitions of nonunion ranged from 2 to 12 months. There was also variability in definitions of fracture malunion. Acceptable degrees of fracture shortening and translation ranged from less than 5 mm to greater than 15 mm. Surgeons' definitions of acceptable angular malunions (rotational, varus/valgus, and procurvatum/recurvatum) ranged from less than 5 degrees to 20 degrees.

CONCLUSIONS

There is a lack of consensus in the assessment of fracture healing in tibial shaft fractures among orthopaedic surgeons. Varying definitions of nonunion and malunion may influence the decision to intervene in an effort to promote fracture healing and/or realign the fracture.

Retransplantation of Multiple Organs: How Many Organs Should One Individual Receive?

Every year, the transplant waiting list gets longer, while donor numbers essentially remain the same. This makes the responsibility of being good stewards of this precious and limited resource greater than ever. Transplant teams, who are both committed to their patients and aware of this important responsibility, are left to make the difficult and ethical decisions regarding retransplantation. Retransplantation of organs in pediatric patients presents a different set of issues to consider, and the results are promising. This case study presents a boy who received a kidney transplant for focal segmental glomerulosclerosis at age 5. At age 11, because of the recurrence of focal segmental glomerulosclerosis and severe cardiomyopathy, he required a rare combined kidney-heart transplant. At age 17, he developed chronic renal failure and posttransplant coronary artery disease, most likely related to a period of noncompliance, and required yet another combined kidney-heart transplant. He is currently alive and well 2 years after transplantation.

[Coronary bypass reoperations: evaluation of 104 cases]

BACKGROUND

Repetitive procedures usually take place in the natural course of coronary heart disease. The aim of this study was to evaluate the risk factors, which affect coronary bypass reoperations, and to compare them with the postoperative results of the coronary first operations and the reoperations.

METHODS

Between January 1995 and January 2000, coronary reoperations were performed in 104 cases (Coronary reoperations group) by the same surgical team. Ninety-nine of them were the first, 3 were the second and 2 were the third reoperations in this group. At the same period of time, 3609 patients underwent coronary bypass procedure as the first operation (Coronary 1. operation group). Eighty-seven patients were male (83.65%), 17 were female (16.35%) and the mean age was 60.82 +/- 9.49 in reoperation group; while among 2916 patients 2223 were male (80.8%), 693 were female (19.2%) and the mean age was 60.37 +/- 9.58 in the first operation group.

RESULTS

Incidence of prolonged ventilation (p = 0.0001), renal dysfunction requiring dialysis (p = 0.01), need for intraaortic balloon pump (p = 0.0001) and prolonged intensive care unit (p = 0.01) and hospital stay (p = 0.01) were significantly higher in reoperation group. The mortality rate was 9.62% in the reoperation group while it was 2.2% in the first operation group (p = 0.0001).

CONCLUSIONS

The high morbidity and mortality of coronary bypass reoperations can be reduced to acceptable levels accordingly with early therapy prior to ventricular dysfunction and clinical deterioration that will improve the outcome in these patients.

[Painful or unstable shoulder after coracoid transfer: result of surgical treatment]

INTRODUCTION

The purpose of this study was to investigate the results of revision surgery for complications related to previous coracoïd transfer for recurrent anterior instability of the shoulder.

MATERIALS AND METHODS

Seventeen patients with previous surgery for anterior shoulder instability underwent a new surgical procedure, because of recurrent instability in 10, and painful shoulder with limitation of motion in 7. A soft tissue procedure (Bankart and/or capsuloplasty) was performed in the 10 unstable shoulders, and a joint debridement with removal of the coracoid transfer in the 7 painful shoulders. The subscapularis was found to be normal in only 2 cases, fibrotic in 11, thin in 3, and teared in 1. The interval between the initial procedure and the revision surgery was eleven years on average.

RESULTS

At an average of 21 months follow-up, the patients were evaluated according to the Duplay scoring system. A radiographic analysis was also performed for all the patients, and a CT-examination for fourteen. The results were good or excellent for 11 patients (70% in the soft tissue procedure group, and 57% in the debridement group with removal of the coracoid transfer), fair for 4, and poor for 2. Clinical evaluation of the subscapularis showed a lag of muscle function in 10 patients. Strength in internal rotation was 3.3 kg lesser in the operated shoulder compared to the opposite side. CT-examination showed that 4 patients presented a significantly fatty degeneration of the subscapularis. Finally on radiographic examination, osteoarthritis was present in 9 patients.The most important preoperative factor that affected the final results was the number of previous surgical procedures.

DISCUSSION

Recurrent instability, problems related to the bone graft or ostheosynthesis material, osteoarthritis, and neurological damage can complicate a coracoid transfer procedure. Our study shows that this procedure can also induce irreversible damage to the subscapularis muscle.

CONCLUSION

Revision surgery for complications related to coracoid transfer for anterior shoulder instability is a challenging procedure. Only 2/3 of patients achieved excellent or satisfactory results. Patients with recurrent instability had better results than those with painful impingement and or osteoarthritis. The high rate of late osteoarthritis and irreversible damage of the subscapularis muscle remain sources of concern.

Total joint replacement: baseline benchmark data for interdisciplinary outcomes management

PURPOSE

The purpose of this review was to define and describe 2 years of adverse outcome variances for elective primary or revision of major total joint replacement in terms of baseline benchmark data.

DESIGN

Descriptive variance.

METHODS

Retrospective review of patients with greater than 4 days in acute care after total joint replacement, patients with unexpected comorbidities that required medical subspecialist management, patients who were transferred to a higher level of care, and patients who did not survive postoperatively.

FINDINGS

This review indicates that patients treated on a higher volume dedicated orthopaedic unit experience fewer adverse outcomes and shorter length of stay than patients treated on a general surgical unit.

CONCLUSIONS

Patients who are treated on a dedicated orthopaedic unit experience significantly fewer adverse outcomes or outcome variations. Costs can be effectively managed, and optimal clinical patient outcomes can be achieved with few complications. Treatment strategies can be used as a template for enhanced care processes for this population.

Surgical management of intra-abdominal infection: is there any evidence?

The aim of this review article was to look at the evidence supporting the surgical treatment of secondary bacterial peritonitis. Because the absolute necessity of adequate source control is not disputable and there is no question that peritoneal toilet (in whichever form) is mandatory, the main bulk of this manuscript is dedicated to the controversial issues of planned relaparotomy and laparostomy. We found little good evidence to support or refute the use of these modalities, but in the absence of evidence, one has to use experience and common sense. Ours suggest that planned relaparotomies combined with laparostomy represent, for the time being, the heaviest weaponry in the surgeon's mechanical armamentarium for the treatment of severe intra-abdominal infection. Even without level II evidence, we are convinced that these therapeutic modalities are life-saving in a well-selected group of patients. One has, however, to know when to stop and how not to harm.

Extension of fusions to the pelvis in idiopathic scoliosis

STUDY DESIGN

Retrospective study of patients after extension of previous scoliosis fusions to the pelvis.

OBJECTIVE

To determine whether modern instrumentation and surgical techniques provide for increased fusion rates with fewer complications.

SUMMARY OF BACKGROUND DATA

Traditionally, long fusions to the pelvis in adults with idiopathic scoliosis have resulted in high complication rates, including pseudarthrosis.

METHODS

The hospital and clinic charts of 41 patients (40 female, 1 male) were reviewed 41 months (range: 24-116) after surgery for extension to the pelvis of previous scoliosis fusions. Thirty-nine of 41 had a combined anteroposterior fusion extension; two had posterior extension only. In 37 of 41 patients, Cotrel-Dubousset (CD) instrumentation was used; in two, Isola (Acromed Corp., Cleveland, OH), in one, TSRH; (Sofamor-Danek, Memphis, TN), and in one, Synergy (Cross Medical Products, Columbus, OH). Parameters analyzed were fusion rate, sagittal and coronal balance, lumbar lordosis, length of fusion extension, and distal fixation method.

RESULTS

Complications were seen in 30 of 41 patients. The pseudarthrosis rate was 37% (15/41) and was significantly related to the method of distal posterior fixation. With sacral fixation only, the rate was 53% (8/15), with iliac fixation only 42% (3/7), and with both iliac and sacral fixation 21% (4/19; P < 0.05). This was not correlated with fusion rate, and the length of fusion extension did not affect the pseudarthrosis rate or sagittal balance.

CONCLUSION

When fixed to the ilium and sacrum, modern instrumentation appears capable of maintaining sagittal balance with lower rates of pseudarthrosis when previous scoliosis fusions are extended to the pelvis. The complication rate remains significant.

Rationing failure. The ethical lessons of the retransplantation of scarce vital organs

Because of a shortage of transplantable livers and hearts, the transplant community has had to decide--by who gets an organ--who lives or dies. Despite this shortage, whether one has previously received a transplant is not used as a criterion to distribute organs. The existing allocation system distributes 10% to 20% of available hearts and livers to retransplant patients. This article examines three differences between primary transplantation and retransplantation that may affect the priority that retransplant candidates should receive in vying for organs: (1) the special obligations that transplant teams have not to abandon patients on whom they have already performed a transplant, (2) the fairness of allowing individuals to get multiple transplants while some die awaiting their first, and (3) the difference in efficacy between primary transplantation and retransplantation. Only this last difference holds up to critical analysis. Our moral duty to direct scarce, lifesaving resources to those likely to benefit from them, suggests that, all other things equal, primary transplant candidates should receive priority because their mortality after transplantation is lower. Consistency also demands that previous transplant history be taken into account, as we already allocate organs according to ABO blood group matching, a factor that affects transplant outcome approximately the same amount as a previous transplantation. We therefore conclude that the system should be revised so that primary transplant candidates have a better chance of receiving organs than retransplant candidates.

Optimal procedure in secondary blepharoplasty

Secondary repair is a common necessity after blepharoplasty. The need stems from faulty methodology in primary aesthetic periorbital repair. Rethinking initial procedures with careful attention to diagnosis, planning, and execution in the light of contemporary knowledge should eliminate the need for most secondary repair. The procedures that have been traditional over the last 50 years are obsolete today, as we have come to a better understanding of blepharoplasty. It is appropriate that conceptualization and technique change to eliminate the massive and growing volume of secondary deformity. Redirecting the focus in secondary repair, both in the upper and lower orbital regions, gives reoperation a greater chance of success, while avoiding ill conceived solutions that accentuate deformity.
