Routine bilateral neck exploration and four-gland dissection remains unnecessary in modern parathyroid surgery.

OBJECTIVE: Recent advances in preoperative imaging techniques and intraoperative parathyroid hormone (ioPTH) assays have made single-gland, minimally invasive parathyroidectomy (MIP) the preferred treatment option for most patients with primary hyperparathyroidism (pHPT). Despite this evolution, a recommendation for bilateral neck exploration (BNE) with four-gland dissection in all patients has recently been advocated by a parathyroid surgical group. The current study compares the long-term outcomes of MIP with those of conventional BNE with four-gland dissection in patients with pHPT. METHODS: In order to objectively assess a recommendation in the literature that universal BNE with four-gland dissection is advisable, all patients undergoing an initial MIP with ioPTH assessment for pHPT in a tertiary endocrine practice during a 10-year period were reviewed. The cure rates from this procedure were compared with published results of conventional BNE with four-gland dissection. RESULTS: Of the 561 patients undergoing parathyroidectomy during the study period, 337 had initial surgery for pHPT; 282 of these patients met inclusion criteria and 212 had sufficient follow-up data available. A single adenoma was identified in 87.3% of cases. Preoperative imaging studies were co-localizing in 148 (69.8%), and 127 (85.8%) of these patients with co-localizing imaging required only single-gland surgery. Imaging studies did not co-localize in 49 patients, yet 32 (65.3%) of these patients were still cured with unilateral surgery. The cure rate for patients undergoing MIP was 98.6%, with a long-term recurrence rate of <2%. CONCLUSION: When coupled with the ioPTH assay, patients with at least one preoperative localizing study can undergo MIP and anticipate a cure rate of 99%, which is as good as or better than the published rates for conventional BNE with four-gland dissection. With unilateral surgery, the risks of permanent hypoparathyroidism and airway obstruction from bilateral vocal fold paralysis are completely eliminated. Therefore, despite recommendations to the contrary, most patients with pHPT should not have a planned four-gland exploration. LEVEL OF EVIDENCE: III or IV.

Protocol driven outcomes in renal parathyroid surgery.

BACKGROUND: Patients who require surgery for renal hyperparathyroidism represent a special population that is at high risk for postoperative complications. To optimize their treatment, we developed a multidisciplinary approach to the perioperative management of these patients undergoing parathyroidectomy. METHODS: The Augusta University endocrine surgery parathyroid database was interrogated to identify dialysis-dependent patients undergoing parathyroidectomy from 2005 to 2015. Numerous clinical parameters were quantified. Patients were stratified into protocol patients and nonprotocol patients. RESULTS: A total of 42 patients undergoing renal parathyroidectomy who met the inclusion criteria were identified. Serious adverse events were nearly twice as common in the patients not treated on protocol. The length of stay was nearly 2 days shorter in the protocol group. Lowest calcium level and ionized calcium was higher in the protocol cohort despite a lower postoperative parathyroid hormone. The protocol group had fewer laboratory draws. CONCLUSION: Implementation of a multidisciplinary renal hyperparathyroidism protocol has resulted in improved perioperative outcomes.

Clinical and epidemiological factors associated with suicide in colorectal cancer.

PURPOSE: While increased suicidal tendencies among cancer patients have been well documented, this study aims to examine suicide rates and factors associated with suicide specifically in patients with colorectal cancer (CRC). METHODS: Patients diagnosed with CRC between the years of 1988-2010 were selected from the Surveillance, Epidemiology, and End Result (SEER) database. Comparisons with the general population were done using the National Center for Disease Control registry. RESULTS: One thousand three hundred eighty-one suicides among 884,529 patients were identified, with a standardized mortality ratio (SMR) of 1.53 (95% CI, 1.13-1.33) compared to the general population. No statistically significant difference in suicide rate was found with respect to age, marital status, socio-economic status, surgical intervention, histologic subtype, or stage at diagnosis. Within the CRC population, Whites were significantly more likely to commit suicide than non-Whites (OR, 2.28; 95% CI, 1.89-2.75; P < 0.001), and males were significantly more likely than females (OR, 5.635; 95% CI, 4.85-6.54; P < 0.001). Most suicides occurred in patients with distal lesions in the sigmoid/rectosigmoid junction (P < 0.001). SMRs for CRC patients were 4.24 for females (95% CI, 3.69-4.86), 1.35 for males (95% CI, 1.28-1.43), 0.38 for African-Americans (95% CI, 0.28-0.52), 1.77 for Whites (95% CI, 1.68-1.87), and 0.90 for other races (95% CI, 0.72-1.12). CONCLUSION: Identification of risk factors associated with suicide among patients with CRC is an important step in developing screening strategies and management of psychosocial stressors. These results could be helpful in formulating a comprehensive suicide risk scoring system for screening all cancer patients.

Baseline intraoperative intact parathyroid hormone levels in parathyroid surgery.

BACKGROUND: We sought to evaluate the relationship between the preoperative core-laboratory parathyroid hormone (CL-PTH) level and the baseline intraoperative PTH (IOPTH) level and assess the impact of any differences on clinical decision making in consecutive surgical patients with primary hyperparathyroidism undergoing parathyroidectomy. METHODS: The CL-PTH and baseline IOPTH levels were compared. The influence of relying on either the CL-PTH or baseline PTH levels for intraoperative decision making was determined. RESULTS: Data were available for 316 patients. Baseline IOPTH measurements were usually higher than the CL-PTH (247 patients; 78.2%) measurements, with a mean difference of 68.2 pg/mL (P < .001). Using the CL-PTH as a surrogate for the baseline parathyroid hormone (PTH) would have prolonged the operation in 23 patients (7.3%). CONCLUSION: Baseline point-of-care IOPTH levels were higher than the preoperative CL-PTH levels in >75% of patients undergoing parathyroidectomy. Using the CL-PTH in lieu of an IOPTH baseline value would prolong the operation in some patients.

Analysis of 334 Cases of Pediatric Esophageal Foreign Body Removal Suggests that Traditional Methods Have Similar Outcomes Whereas a Magnetic Tip Orogastric Tube Appears to Be an Effective, Efficient, and Safe Technique for Disc Battery Removal.

Procedures and outcomes for pediatric esophageal foreign body removal were analyzed. Traditional methods of battery removal were compared with a magnetic tip orogastric tube (MtOGT). A single institution retrospective review from 1997 to 2014 of pediatric patients with esophageal foreign bodies was performed. Balloon extraction with fluoroscopy (performed in 173 patients with 91% success), flexible endoscopy (92% success in 102 patients), and rigid esophagoscopy (95% in 38 patients) had excellent success rates. A MtOGT had 100 per cent success in six disc battery patients, when other methods were more likely to fail, and was the fastest. Power analysis suggested 20 patients in the MtOGT group would be needed for significant savings in procedural time. Thirty-two per cent of all foreign bodies and 95 per cent of batteries had complications (P = 0.002) because of the foreign body. Overall, 1.2 per cent had severe complications, whereas 10 per cent of batteries had severe complications (P = 0.04). Each technique if applied appropriately can be a reasonable option for esophageal foreign body removal. Magnetic tip orogastric tubes used to extract ferromagnetic objects like disc batteries had the shortest procedure time and highest success rate although it was not statistically significant. Disc batteries require emergent removal and have a significant complication rate.

Demographic and clinical factors associated with suicide in gastric cancer in the United States.

While increased suicidal tendencies among cancer patients have been well documented, there has been no specific examination of suicide and gastric cancer. The purpose of this study is to characterize suicide incidence among patients diagnosed with gastric cancer from 1973 to 2013 and identify variables associated with higher suicide rates. Patients with gastric cancer were identified in the Surveillance, Epidemiology, and End Results (SEER) database of the National Cancer Institute. The study included clinical and demographic data from 1973 to 2013. Standardized mortality ratios (SMRs) and 95% confidence intervals (95% CIs) were calculated. Comparisons with the general US population were based on mortality data collected by the Centers for Disease Control and Prevention's National Center for Injury Prevention and Control using the Web-based Injury Statistics Query and Reporting System. Multivariable logistic regression models generated odds ratios (ORs) to assess factors associated with increased suicide in gastric malignancy. There were 210 suicides for patients with gastric cancer (SMR, 3.21; 95% CI: 2.80-3.67). Female gender (SMR 8.54), White race (SMR 4.08), age ≤39 years (SMR 3.06), and age 70-79 years (SMR 2.90), were found to be significant for an increased incidence of suicide compared with the general population. There was not a statistically significant relationship between suicide and marital status, income, mode of radiation therapy, and the role of surgical intervention. Approximately 77% of deaths by suicide occurred within the first year following diagnosis. Female gender, White race, age ≤39 years, and age 70-79 years are factors associated with increased risk of suicide in patients with gastric cancer. These results, coupled with further studies and analyses, will be used to formulate a comprehensive suicide risk factor scoring system for screening all cancer patients.

Thoracic Trauma in the Oldest of the Old: An Analysis of the Nationwide Inpatient Sample.

Thoracic trauma (TT) has the second highest mortality rate in the geriatric population. These injuries cause significant morbidity in elderly patients. Little has been done to describe the demographics and mortality of specific injuries in these patients. ICD-9 codes corresponding with thoracic trauma for patients aged >80 years were extracted from the Nationwide Inpatient Sample database from 2000 to 2010. Characteristics including gender, race, Charlson Comorbidity Index (CCI), length of stay (LOS), and in-hospital mortality (IHM) were analyzed. For females and males, mean CCI was 4.84 and 4.93, respectively (P < 0.0001), and IHM was 5.49 and 2.44 per cent, respectively (P < 0.0001). For white and non-white patients, mean CCI was 4.88 and 4.84, respectively (P < 0.05), and IHM was 3.5 and 3.19 per cent, respectively. This difference was not statistically significant (P = 0.149). Logistic regression revealed correlation coefficient between CCI and mortality was 0.314 (P < 0.0001). Fitting a regression of CCI on LOS adjusting for gender and race, the adjusted effect was 0.146 (P < 0.0001). LOS was significantly less for patients surviving hospitalization. Males had higher CCI and mortality than females. Although whites had a higher CCI than non-whites, there was no difference in IHM between these two groups.
