To examine opioid prescribing patterns after general surgery procedures and to estimate an ideal number of pills to prescribe.
Diversion of prescription opioids is a major contributor to the rising ...mortality from opioid overdoses. Data to inform surgeons on the optimal dose of opioids to prescribe after common general surgical procedures is lacking.
We evaluated 642 patients undergoing 5 outpatient procedures: partial mastectomy (PM), partial mastectomy with sentinel lymph node biopsy (PM SLNB), laparoscopic cholecystectomy (LC), laparoscopic inguinal hernia repair (LIH), and open inguinal hernia repair (IH). Postoperative opioid prescriptions and refill data were tabulated. A phone survey was conducted to determine the number of opioid pills taken.
There was a wide variation in the number of opioid pills prescribed to patients undergoing the same operation. The median number (and range) prescribed were: PM 20 (0-50), PM SLNB 20 (0-60), LC 30 (0-100), LIH 30 (15-70), and IH 30 (15-120). Only 28% of the prescribed pills were taken. This percentage varied by operation: PM 15%, PM SLNB 25%, LC 33%, LIH 15%, and IH 31%. Less than 2% of patients obtained refills.We identified the number of pills that would fully supply the opioid needs of 80% of patients undergoing each operation: PM 5, PM SLNB 10, LC 15, LIH 15, and IH 15. If this number were prescribed, the number of opioid initially prescribed would be 43% of the actual number prescribed.
There is wide variability in opioid prescriptions for common general surgery procedures. In many cases excess pills are prescribed. Using our ideal number, surgeons can adequately treat postoperative pain and markedly decrease the number of opioids prescribed.
The aim of this study was to determine whether an educational intervention was sufficient to decrease opioid prescribing after general surgical operations.
We recently analyzed opioid prescription ...and use for 5 common outpatient operations at our institution: partial mastectomy (PM), PM with sentinel lymph node biopsy (PM SLNB), laparoscopic cholecystectomy (LC), laparoscopic inguinal hernia repair (LIH), and open inguinal hernia repair (IH). We found that opioids were over-prescribed. We formulated guidelines for opioid prescribing that would halve the number of pills prescribed and also satisfy 80% of patients' opioid requirements.
We discussed our findings and opioid-prescribing guidelines with surgeons at our institution. We recommended that surgeons encourage patients to use a nonsteroidal anti-inflammatory drug (NSAID) and acetaminophen before using opioids. We then evaluated opioid prescriptions and use in 246 subsequent patients undergoing these same operations.
The mean number of opioid pills prescribed for each operation markedly decreased: PM 19.8 versus 5.1; PM SLNB 23.7 versus 9.6; LC 35.2 versus 19.4; LIH 33.8 versus 19.3, and IH 33.2 versus 18.3; all P < 0.0003. The total number of pills prescribed decreased by 53% when compared with the number that would have been prescribed before the educational intervention. Only 1 patient (0.4%) required a refill opioid prescription. Eighty-five percent of patients used either a NSAID or acetaminophen.
By defining postoperative opioid requirements through patient surveys and disseminating operation-specific guidelines for opioid prescribing to surgeons, we were able to decrease the number of opioids initially prescribed by more than half. Decreased initial opioid prescriptions did not result in increased opioid refill prescriptions.
There is a paucity of data to inform appropriate opioid prescribing for patients who are discharged after a hospital admission for a surgical procedure.
We studied 333 inpatients discharged to home ...after bariatric, benign foregut, liver, pancreas, ventral hernia, and colon surgery. Chronic opioid users or patients who had complications were excluded. Home opioid usage was quantified in 90% of the remaining patients by questionnaires and phone surveys.
Eighty-five percent of patients were prescribed an opioid and 38% of prescribed opioid pills were taken. Fifteen opioid pills satisfied the opioid needs of 88% of patients discharged on postoperative day (POD) 1. For patients discharged after POD 1, in multivariate analysis, the number of opioid pills used at home was associated with the number taken the day before discharge (p < 0.0001) and patient age (p = 0.006), but not the type of surgery. Forty-one percent of patients took no opioids the day before discharge, 33% took 1 to 3, and 26% took more than 4 pills. Eighty-five percent of patients' home opioid requirements would be satisfied using the following guideline: if no opioid pills are taken the day before discharge, no prescription is needed; if 1 to 3 opioid pills are taken the day before discharge, then a prescription for 15 opioid pills is given at discharge; and if 4 or more pills are taken the day before discharge, then a prescription for 30 opioid pills is given at discharge. If these guidelines were used, the number of opioid pills prescribed would decrease by 40%.
For patients admitted after surgical procedures, post-discharge opioid use is best predicted by usage the day before discharge. Use of this guideline could decrease opioid prescriptions substantially and effectively treat patients' pain.
Background
It is unknown whether the identification of additional tumors in the breast using preoperative magnetic resonance imaging (pMRI) results in a lower risk of in-breast tumor recurrence ...(IBTR) after breast-conserving surgery (BCS).
Methods
A systematic review and meta-analysis of relevant studies were performed. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.
Results
From 768 citations, 20 studies met the inclusion criteria for the systematic review. The 20 studies consisted of 14 retrospective reviews, 3 matched cohorts, and 3 randomized controlled trials. Whereas 2 studies reported a statistically significant lower rate of IBTR with pMRI, 18 studies showed no difference, and no studies reported a higher rate. Of the 18 studies showing no significant difference, 12 demonstrated a trend toward a lower IBTR rate in the pMRI group. The criteria for meta-analysis were met by 16 studies. A meta-analysis of 11 studies that reported hazard ratios (HR) for IBTR showed a trend toward a lower rate of IBTR for patients who received preoperative MRI (hazard ratio (HR), 0.89; 95% confidence interval (CI), 0.74–1.05). A meta-analysis of five studies that reported event rates and had similar follow-up duration for both groups demonstrated a lower relative risk (RR) of IBTR (RR, 0.45; 95% CI 0.25–0.81).
Conclusions
Although some evidence supports the hypothesis that identification of additional tumors in the breast using pMRI results in lower rates of IBTR after BCS, the main meta-analysis in this study did not confirm this hypothesis.

Opioid overdose is the leading cause of injury-related death in the United States. Several studies have shown that surgeons overprescribe opioids, and guidelines for appropriate opioid prescribing ...are available. Concern about patient-reported satisfaction scores may be a barrier to surgeons adopting guideline-directed prescribing.
To determine whether decreased opioid prescribing is associated with a decrease in patient-reported satisfaction with their surgeon.
Retrospective analysis of clinician satisfaction scores at Dartmouth-Hitchcock Medical Center obtained in 2 periods: 1 before (period A) and 1 after (period B) an educational intervention that resulted in decreased opioid prescribing. The analysis included 11 surgeons who performed 5 common outpatient general surgical operations on 996 patients. Data were analyzed between March and August 2018.
Patient-reported overall satisfaction rating of the surgeon (scale, 0-10). This was collected by a nonstudy-related, routine general institutional survey of approximately 40% of all outpatient encounters.
Of the total number of patients, 67% were women (667 of 996), and the mean patient age was 58 years. Comparing period A with B, the proportion of patients prescribed opioids decreased from 90.2% (n = 367 of 407) to 72.8% (n = 429 of 589) (P < .001). The mean number of opioid pills per prescription decreased from 28.3 to 13.3 (P < .001) and significantly decreased for each of the 11 surgeons. One hundred five of 996 patients (10.5%) undergoing index operations responded to the survey. There was no difference in the mean clinician satisfaction ratings from period A vs B (9.70 vs 9.65; P = .69). During the study periods, 640 total surveys were collected referencing these surgeons (including outpatient encounters associated with operations other than the 5 index cases). There was no difference in the mean satisfaction ratings from period A vs period B (9.55 vs 9.59; P = .62). When individual clinicians were analyzed, none had a significant difference in overall satisfaction rating from period A vs period B.
Despite a marked decrease in the proportion of patients receiving opioids and in the number of pills prescribed, there was no significant change in clinician satisfaction ratings.
MicroRNAs (miRNAs) are RNA molecules that are involved in the regulation of many cellular processes, including those related to human cancers. The aim of this study was to determine, as a proof of ...principle, whether specific candidate miRNAs could be detected in fine-needle aspirate (FNA) biopsies of pancreatic ductal adenocarcinoma (PDAC) and could accurately differentiate malignant from benign pancreatic tissues.
We used TaqMan(R) assays to quantify miRNA levels in FNA samples collected in RNARetain (n = 16) and compared the results with a training set consisting of frozen macrodissected pancreatic samples (n = 20).
Quantitative reverse-transcription PCR analysis confirmed that miRNA levels are affected in PDAC FNAs and correlate well with the changes observed in the training set of frozen pancreatic samples. Analysis of the amounts produced for a few specific miRNAs enabled identification of PDAC samples. The combination of miR-196a and miR-217 biomarkers further improved the ability to distinguish between healthy tissue, PDAC, and chronic pancreatitis in the training set (P = 8.2 x 10(-10)), as well as segregate PDAC FNA samples from other FNA samples (P = 1.1 x 10(-5)). Furthermore, we showed that miR-196a production is likely specific to PDAC cells and that its incidence paralleled the progression of PDAC.
To the best of our knowledge, this study is the first to evaluate the diagnostic potential of miRNAs in a clinical setting and has shown that miRNA analysis of pancreatic FNA biopsy samples can aid in the pathologic evaluation of suspicious cases and may provide a new strategy for improving the diagnosis of pancreatic diseases.
Some epithelial neoplasms of the appendix, including low-grade appendiceal mucinous neoplasm and adenocarcinoma, can result in pseudomyxoma peritonei (PMP). Little is known about the mutational ...spectra of these tumor types and whether mutations may be of clinical significance with respect to therapeutic selection. In this study, we identified somatic mutations using the Ion Torrent AmpliSeq Cancer Hotspot Panel v2.
Specimens consisted of 3 nonneoplastic retention cysts/mucocele, 15 low-grade mucinous neoplasms (LAMNs), 8 low-grade/well-differentiated mucinous adenocarcinomas with pseudomyxoma peritonei, and 12 adenocarcinomas with/without goblet cell/signet ring cell features. Barcoded libraries were prepared from up to 10 ng of extracted DNA and multiplexed on single 318 chips for sequencing. Data analysis was performed using Golden Helix SVS. Variants that remained after the analysis pipeline were individually interrogated using the Integrative Genomics Viewer.
A single Janus kinase 3 (JAK3) mutation was detected in the mucocele group. Eight mutations were identified in the V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) and GNAS complex locus (GNAS) genes among LAMN samples. Additional gene mutations were identified in the AKT1 (v-akt murine thymoma viral oncogene homolog 1), APC (adenomatous polyposis coli), JAK3, MET (met proto-oncogene), phosphatidylinositol-4,5-bisphosphate 3-kinase (PIK3CA), RB1 (retinoblastoma 1), STK11 (serine/threonine kinase 11), and tumor protein p53 (TP53) genes. Among the PMPs, 6 mutations were detected in the KRAS gene and also in the GNAS, TP53, and RB1 genes. Appendiceal cancers showed mutations in the APC, ATM (ataxia telangiectasia mutated), KRAS, IDH1 isocitrate dehydrogenase 1 (NADP+), NRAS neuroblastoma RAS viral (v-ras) oncogene homolog, PIK3CA, SMAD4 (SMAD family member 4), and TP53 genes.
Our results suggest molecular heterogeneity among epithelial tumors of the appendix. Next generation sequencing efforts have identified mutational spectra in several subtypes of these tumors that may suggest a phenotypic heterogeneity showing mutations that are relevant for targeted therapies.
