Pleurodesis in Patients with Malignant Pleural Effusions: Talc Slurry or Bleomycin? Results of a Prospective Randomized Trial

The purpose of this study was to evaluate the efficacy, safety, and cost of bedside pleurodesis for malignant pleural effusions using talc slurry (TS) or bleomycin (BL) in a prospective randomized trial, and to determine prognosticators for procedure failure. From June 1997 to June 1999 a series of 71 patients entered this trial. They underwent 37 procedures with TS (4 g) and 34 with BL (60 units) via tube thoracostomy. Success was defined as no recurrence of pleural effusion or asymptomatic recurrence of a small amount of effusion. Pleural effusion-free survival curves were used to analyze the success rates and the prognosticators of failure. Follow-up ranged from 3 days to 26 months (median 2.5 months). No difference in success rates was detected between TS or BL (log-rank test: p = 0.724). There were no major complications related to the procedure. The independent prognosticators of failed pleurodesis were the use of steroids (p = 0.004) and the volume of pleural fluid drained during the first thoracentesis when it was more than 900 ml (p = 0.029). The average cost of intervention per patient was significantly lower for TS (p < 0.001). There was no significant difference between the success rates for TS and BL as agents of bedside pleurodesis for malignant pleural effusions. Because of its significantly lower cost, TS should be considered the agent of choice. The use of steroids and the volume drained during the first thoracentesis (if more than 900 ml) were independent prognosticators of pleurodesis failure. The role of this latter finding as a marker of pleurodesis failure awaits more data.     

Introduction of an OPCAB Program Aimed at Total Arterial Grafting in a Multidisciplinary Setting: Feasible and Safe?

BACKGROUND: The feasibility and the results of the introduction of an off-pump coronary artery bypass (OPCAB) program aimed at total arterial revascularization in a multidisciplinary institution were analyzed. Uniform surgical and anesthetic protocols were established and applied throughout the study period. METHODS: From March 2003--when the first OPCAB procedure of the program was performed--to July 2004, the data related to all the coronary artery bypass grafting procedures (N = 408) were prospectively recorded. The program was divided into two stages: the purpose of the first stage was to perform OPCAB in more than 90% of the patients, and that of the second stage was to proceed toward total arterial revascularization. The patients were grouped into four periods (102 patients for each period). Comparisons were performed with analysis of variance test and chi-square test where appropriate. RESULTS: For periods 1 to 4, the number of OPCAB procedures was 65/102 (64%), 82/102 (80%), 97/102 (95%), and 99/102 (97%), respectively (p < 0.001). The number of conversions did not vary significantly throughout the study (overall: 7/408, 1.7%), neither did the number of bypass/patient (overall: 3.05 +/- 0.86). The number of arterial graft/patient was 1.03 +/- 0.64, 1.01 +/- 0.4, 1.29 +/- 0.64, and 2.56 +/- 1, respectively (p < 0.001). During the last period, 81% (253/312) of the grafts were arterial. Overall mortality was 4.6% (19/408). For the OPCAB group, mortality was 2.9% (10/343) and perioperative myocardial infarction rate was 1.5% (5/343) with no statistically significant difference between the periods. CONCLUSIONS: With predefined standardized and coordinated protocols, an OPCAB program aimed at total arterial revascularization can be implemented rapidly and safely in a multidisciplinary setting.     

Is an “Outpatient Arthroplasty Risk Assessment Score” Needed for Predicting Safe Selection of Outpatient Arthroplasty Candidates?

BackgroundTotal joint arthroplasty is rapidly shifting to the outpatient space. One of the challenges of same-day discharge adoption has been determining which patients are suitable candidates. Risk assessment tools have been developed, including the Outpatient Arthroplasty Risk Assessment (OARA) score. The purpose of this study was to assess its predictive utility.MethodsA retrospective review was performed on all total joint arthroplasties performed at a single ambulatory surgery center in 2018, yielding a cohort of 1,105 patients (1,332 arthroplasties). The institution’s outpatient criteria required optimization of all medical conditions; if the patient had no failing organ, they were candidates for same-day discharge. OARA scores were calculated based on preoperative histories and physical examinations. Analyses were performed on the statistical utility of the OARA score in predicting successful same-day discharge. The mean age was 59 years (range, 27-82), the mean body mass index was 33.3 kg/m² (range, 16-66), and 51.5% were women. A total of 45% of patients had one or more major comorbidity.ResultsThere were 81.6% of patients who had an acceptable OARA score (<60). In addition, 97% of patients who had an “unacceptable” OARA score were successfully discharged the same day. There were 23 patients who required inpatient observation; of these, 7 (30.4%) had an OARA score ≥60.ConclusionThe OARA score was accurate in predicting patients who successfully had same-day discharge but poor at predicting who would not. This system is time consuming and may be too restrictive on which patients are candidates for outpatient arthroplasty. Surgeons may consider a more simplified criteria for outpatient arthroplasty.

Is Unilateral Neck Surgery Feasible in Patients with Sporadic Primary Hyperparathyroidism and Double Negative Localisation?

Introduction

Ultrasound and Tc99mMIBI scans are used to localise parathyroid tumours in sporadic primary hyperparathyroidism (pHPT). Intra-operative PTH (ioPTH) assay facilitates unilateral neck exploration (UNE). When both ultrasound and MIBI are negative, it is our policy to explore the left side of the neck and only proceed to bilateral neck exploration (BNE) when either a tumour is not found or when ioPTH does not fall to >50% of the highest pre-excision value. The aim of this study was to investigate the outcome of our approach to ‘double negative’ patients.

Methods

A retrospective analysis of patients undergoing primary parathyroidectomy for pHPT. Data were obtained from a prospective surgical database and the hospital electronic patient record.

Results

Between January 2004 and November 2014, 746 patients underwent a parathyroidectomy for pHPT. Those who did not have both pre-operative scans, ioPTH or a minimum of 6-month follow-up were excluded. Of 552 patients, 111 (20%) had double negative scans (group A), and in 441, either one or both scans were positive (group B). Median age was 61.5 years (range 10–88). Pre-operative PTH level was significantly lower in group A: 11.8 pmol/l (range 3.1–38.8) versus 14.9 pmol/l (range 2.8–101.6; P < 0.01). Median tumour weight was significantly lower in group A: 280 mg (range 50–3710) versus 573 mg (range 10–12,000; P < 0.01). Overall rate of multiple gland disease (MGD) was 11%; 24% in group A and 7% in group B (P < 0.01). Overall rate of UNE in Group A was 28% and converse to the rate in Group B (76%; P < 0.01). Sensitivity and specificity of ioPTH to detect MGD were 98 and 98% in Group A versus 98 and 100% in Group B. First-time cure rate was 92.7% in group A and 96.8% in group B (P < 0.05).

Conclusion

A double negative scan is associated with small tumours and higher rates of MGD. Despite these challenges, surgery is successful in this group of patients reinforcing the message that negative localisation is not a contraindication for parathyroidectomy. We demonstrated that it is feasible to offer unilateral neck surgery to 28% of patients with double negative scans. A randomised trial is needed to compare BNE with ioPTH/UNE in this select population.

     

Do Concomitant Ascites Influence the Effectiveness of Palliative Surgical Management of Pleural Effusion in Patients with Malignancies?

Background  Both pleural and peritoneal effusions are associated with dismal prognosis for patients with malignancies. Pleural effusion often requires surgical palliative management to relieve symptoms. The aim of this study was assess the influence of concomitancy of ascites on the success rate of surgical management of pleural effusion in patients with solid malignancies. Methods  We retrospectively identified 33 patients with different primary malignancies, who underwent palliative surgical treatment for pleural effusion with concomitant ascites. The success rate of pleural effusion management was compared to that of a control group of patients with pleural effusion without ascites. Results  Ovarian and breast cancer were the most common primary sites in the group of patients with pleural and peritoneal effusions. Thoracocentesis was performed in 30 patients with concomitant ascites and in 29 patients without ascites. The median number of thoracocentesis procedures was two in both groups of patients. Talc pleurodesis was performed in 57.6 and 63.3% of patients with and without ascites, respectively. The success rate of pleurodesis was 68.4 and 71.9% for patients with and without concomitant ascites (P = 0.92), respectively. There was no significant difference in the median length of time of the chest tube placement between the two groups (with ascites, 6 days; without ascites, 5 days, P = 0.38). The overall survival was 5.6 months for patients with ascites and 7.8 months for patients without ascites (P = 0.51). Conclusion  Our results suggest that concomitant ascites did not influence the effectiveness of palliative surgical management of pleural effusion in patients with malignancies.     

Is Cytomegalovirus Surveillance Necessary for Patients With Low Reactivation Risk in an Autologous Hematopoietic Cell Transplantation Setting?

Background

In an autologous hematopoietic cell transplantation (AHCT) setting, routine cytomegalovirus (CMV) surveillance is not indicated except in high-risk situations. On the other hand, some studies reported increased CMV reactivation in AHCT setting as a result of incorporation of novel agents into treatment algorithms, such as bortezomib and rituximab. We retrospectively analyzed CMV reactivation and infection rates in patients with no high-risk features, who were treated with AHCT.

Bilateral Neck Exploration in Primary Hyperparathyroidism—When Is It Selected and How Is It Performed?

Background  

Although most patients with primary hyperparathyroidism (PHPT) are ideal candidates for minimally invasive parathyroidectomy, some will have more than one enlarged gland and require bilateral neck exploration to achieve biochemical cure. We evaluated the clinical evidence for when to choose bilateral neck exploration for patients with PHPT.     

When Is Prophylactic Thyroidectomy Indicated for Patients with the RET Codon 609 Mutation?

Background  Mutations in the RET proto-oncogene cause multiple endocrine neoplasia type 2A (MEN2A), and prophylactic thyroidectomy has generally been recommended before the age of 5 years. Patients with codon 609 mutations develop MTC at a later age and therefore the timing of prophylactic thyroidectomy is less clear. We report a three-generation family with C609Y RET mutation where members having prophylactic or therapeutic thyroidectomy call the current recommendations for age at thyroidectomy into question. Methods  Sixteen family members underwent thyroidectomy, for which clinical, laboratory, and pathological data were analyzed. A literature review of RET codon 609 mutations was carried out. Results  Data were collected from 16 patients from this 38-member kindred. None of these affected members had pheochromocytoma, and one had a parathyroid adenoma. Nine of 16 patients had MTC (mean age 44.7 years, range 29–59 years) and elevated basal calcitonin levels; 6 of these 9 had lymph node metastases. Two patients had C-cell hyperplasia (CCH) at ages 18 and 37 years, and five patients had normal thyroid pathology (mean age 16 years, range 5–37 years). In the literature, a family with C609Y mutation was reported, with 15 members having MTC (mean age 42 years, range 21–59 years), and 6 with CCH (mean age 24 years, range 15–37 years). Conclusion  The youngest patient with C609Y RET mutation and MTC was 21 years old, and the youngest patient with CCH was 15 years old at diagnosis. These data suggest that patients with RET C609Y mutations can delay thyroidectomy until 10–15 years of age, with annual calcitonin screening prior to thyroidectomy.     

Is Hypoalbuminemia an Independent Prognostic Factor in Patients with Gastric Cancer?

Background  

Studies have indicated that hypoalbuminemia is associated with decreased survival of patients with gastric cancer. However, the prognostic value of albumin may be secondary to an ongoing systemic inflammatory response. The aim of the study was to assess the relation between hypoalbuminemia, the systemic inflammatory response, and survival in patients with gastric cancer.     

Hospital Discharge in the Day Following Open Roux-en-Y Gastric Bypass: Is it Feasible and Safe?

Background  Roux-en-Y gastric bypass (RYGBP) either laparoscopic or open has been increasingly employed in the treatment of patients with morbid obesity. Laparoscopic approach is believed to be superior over open approach in terms of shorter hospital stay and easier recovery. We aimed to assess feasibility and safety of open RYGBP with short stay in comparison with laparoscopic RYGBP. Methods  One hundred and ninety consecutive patients were assigned to open (n = 103) or laparoscopic (n = 87) RYGBP. The first 20 patients of the laparoscopic arm were excluded due to procedure learning curve. Patients were treated by a multidisciplinary team focused on successfully RYGBP with short stay (1 day). Results  Short stay was reached by 90% of patients operated with open approach and 81% by laparoscopy (P = 0.070). Discharge in the second day was reached by 97% of patients in both groups. Procedure length [(median (IQR)] was faster for open RYGBP [103 (70–180 min) vs. 169 (105–248 min); P < 0.0001]. Thirty-day readmission rate was similar between groups (3% vs. 7%; P = 0.266). There was no death in either group. Conclusion  Short stay (1 day) following open gastric bypass was a feasible and safe procedure. This approach might have economic impact and might increase patient acceptance for open RYGBP.     

Is Neuraxial Anesthesia Safe in Patients Undergoing Surgery for Treatment of Periprosthetic Joint Infection?

BackgroundThere is concern that neuraxial anesthesia in patients undergoing surgery for treatment of a periprosthetic joint infection (PJI) may increase the risk of having a central nervous system infection develop. However, the available data on this topic are limited and contradictory.Questions/purposesWe wished to determine whether neuraxial anesthesia (1) is associated with central nervous system infections in patients undergoing surgery for a PJI, and (2) increases the likelihood of systemic infection in these patients.MethodsAll 539 patients who received neuraxial or general anesthesia during 1499 surgeries for PJI from October 2000 to May 2013 were included in this study; of these, 51% (n = 764) of the surgeries were performed in 134 patients receiving neuraxial anesthesia and 49% were performed in 143 patients receiving general anesthesia. Two hundred sixty-two patients received general and neuraxial anesthesia during different surgeries. We used the International Classification of Diseases, 9^th Revision codes and the medical records to identify patients who had an intraspinal abscess or meningitis develop after surgery for a PJI. Multivariate analysis was used to assess the effect of type of anesthesia (neuraxial versus general) on postoperative complications.ResultsThere were no cases of meningitis, but one epidural abscess developed in a patient after neuraxial anesthesia. This patient underwent six revision surgeries during a 42-day period. Patients who received neuraxial anesthesia had lower odds of systemic infections (4% versus 12%; odds ratio, 0.35; 95% CI, 023–054; p < 0.001).ConclusionsCentral nervous system infections after neuraxial anesthesia in patients with a PJI appear to be exceedingly rare. Based on the findings of this study, it may be time for the anesthesiology community to reevaluate the risk of sepsis as a relative contraindication to the use of neuraxial anesthesia.

Is It Possible and Safe to Perform Acetabular-preserving Resections for Malignant Neoplasms of the Periacetabular Region?

Background

Primary malignant tumors located near the acetabulum are usually managed by resection of the tumor with wide margins that include the acetabulum. These resections are deemed P2 resections by the Enneking and Dunham classification. There are various methods to perform the subsequent hip reconstruction. Unfortunately, there is no consensus as to the best management. In general, patients undergoing resection at this level will have substantial levels of pain and disability as measured by the Musculoskeletal Tumor Society (MSTS) scoring system. We believe there is a subset of patients whose tumors in this location can be resected while preserving all or most of the weightbearing acetabulum using navigation and careful surgical planning.

Questions/purposes

(1) What complications were associated with this resection; (2) what oncological outcomes (histological margins and local recurrence) were achieved; and (3) what is the function achieved by these patients?

Methods

This was a retrospective study of patients with periacetabular primary malignancy. From 2008 to 2014, we treated 12 patients who had periacetabular primary malignant tumors and in five, we performed resection with the weightbearing portion spared. During this period, our general indications to perform a resection that spared the acetabulum were the tumor with its resection margin not involving the weightbearing portion of the acetabulum. However, we did not perform this procedure in patients who had more cranial lesion involving the weightbearing portion or whose hip stability might be in question after the tumor excision. Three patients were women and the other two were men. Four were chondrosarcomas, whereas the other one was synovial sarcoma. Ages ranged from 46 to 60 years (average, 53 years). Minimum followup was 14 months (median, 37 months; range, 14–88 months); no patients were lost to followup before a 1-year minimum was achieved, and all patients have been seen within the last 9 months.

Results

There were no intraoperative or early postoperative complications. None of the five patients had a positive margin by histological assessment. No local recurrences were detected. The median functional score by MSTS was 28 out of 30 (range, 27–30).

Conclusions

The roof of the acetabulum is the weightbearing portion of the acetabulum. It also maintains the stability of the hip. With precise preoperative planning of the resection and accurate execution of the procedure, the hip-sparing approach through partial acetabular resection can be performed in selected patients with malignant periacetabular neoplasms. Navigation makes it possible to minimize the amount of bone resection. In this preliminary report of a small number of patients, we had adequate short-term local tumor control. We believe the function is good, but we do not have a comparison group of patients to document improved function.

Level of Evidence

Level IV, therapeutic study.

     

A Review of Risk Factors and Timing for Postoperative Hematoma After Thyroidectomy: Is Outpatient Thyroidectomy Really Safe?

Background

Although postoperative hematoma after thyroidectomy is uncommon, patients traditionally have been advised to stay overnight in the hospital for monitoring. With the growing demand for outpatient thyroidectomy, we assessed its safety and feasibility by evaluating the potential risk factors and timing of postoperative hematoma after thyroidectomy.

Methods

From 1995–2011, 3,086 consecutive patients underwent thyroidectomy at our institution; of these, 22 (0.7?%) developed a postoperative hematoma that required surgical reexploration (group I). Potential risk factors were compared between group I and those without hematoma (n?=?3,045) or with hematoma but not requiring reexploration (n?=?19; group II). Variables that were significant in the univariate analysis were entered into multivariate analysis by binary logistic regression analysis.

Results

Group I was significantly more likely to have undergone previous thyroid operation than group II (27.3 vs. 8.2?%, p?=?0.007). The median weight of excised thyroid gland (71.8 vs. 40?g, p?=?0.018) and the median size of the dominant nodule (4.1 vs. 3?cm, p?=?0.004) were significantly greater in group I than group II. Previous thyroid operation (odds ratio (OR)?=?4.084; 95?% confidence interval (CI), 1.105–15.098; p?=?0.035) and size of dominant nodule (OR?=?1.315; 95?% CI, 1.024–1.687; p?=?0.032) were independent factors for hematoma. Sixteen (72.7?%) had hematoma within 6?h, whereas the other 6 (27.3?%) had hematoma at 6–24?h.

Conclusions

Previous thyroid operation and large dominant nodule were independent risk factors for hematoma requiring surgical reexploration. Given that a quarter of hematoma occurred between 6 to 24?h after surgery, routine outpatient thyroidectomy could not be recommended.
