Heller myotomy versus Heller myotomy with Dor fundoplication for achalasia: long-term symptomatic follow-up of a prospective randomized controlled trial.

BACKGROUND: Our prior randomized controlled trial of Heller myotomy alone versus Heller plus Dor fundoplication for achalasia from 2000 to 2004 demonstrated comparable postoperative resolution of dysphagia but less gastroesophageal reflux after Heller plus Dor. Patient-reported outcomes are needed to determine whether the findings are sustained long-term. METHODS: We actively engaged participants from the prior randomized cohort, making up to six contact attempts per person using telephone, mail, and electronic messaging. We collected patient-reported measures of dysphagia and gastroesophageal reflux using the Dysphagia Score and the Gastroesophageal Reflux Disease-Health-Related Quality of Life (GERD-HRQL) instrument. Patient-reported re-interventions for dysphagia were verified by obtaining longitudinal medical records. RESULTS: Among living participants, 27/41 (66%) were contacted and all completed the follow-up study at a mean of 11.8 years postoperatively. Median Dysphagia Scores and GERD-HRQL scores were slightly worse for Heller than Heller plus Dor but were not statistically different (6 vs 3, p = 0.08 for dysphagia, 15 vs 13, p = 0.25 for reflux). Five patients in the Heller group and 6 in Heller plus Dor underwent re-intervention for dysphagia with most occurring more than five years postoperatively. One patient in each group underwent redo Heller myotomy and subsequent esophagectomy. Nearly all patients (96%) would undergo operation again. CONCLUSIONS: Long-term patient-reported outcomes after Heller alone and Heller plus Dor for achalasia are comparable, providing support for either procedure.

Association Between Response to Acid-Suppression Therapy and Efficacy of Antireflux Surgery in Patients With Extraesophageal Reflux.

BACKGROUND & AIMS: The effectiveness of antireflux surgery (ARS) varies among patients with extraesophageal manifestations of gastroesophageal reflux disease (GERD). By studying a cohort of patients with primary extraesophageal symptoms and abnormal physiologic markers for GERD, we aimed to identify factors associated with positive outcomes from surgery, and compare outcomes to those with typical esophageal manifestations of GERD. METHODS: We performed a retrospective cohort study to compare adult patients with extraesophageal and typical reflux symptoms who underwent de novo ARS from 2004 through 2012 at a tertiary care center. All 115 patients (79 with typical GERD and 36 with extraesophageal manifestations of GERD) had evidence of abnormal distal esophageal acid exposure based on pH testing or endoscopy. The principle outcome was time to primary symptom recurrence after surgery, based on patient reports of partial or total recurrence of symptoms at follow-up visits. Patients were followed up for a median duration of 66 months (interquartile range, 52-77 mo). RESULTS: The median time to recurrence of symptoms in the overall cohort was 68 months (11.5 months in the extraesophageal cohort vs >132 months in the typical cohort). Symptom recurrence after ARS was associated with having primarily extraesophageal symptoms (adjusted hazard ratio, 2.34; 95% confidence interval, 1.31-4.17) and poor preoperative symptom response to acid-suppression therapy (AST) (hazard ratio, 3.85; 95% confidence interval, 2.05-7.22). Patients with primary extraesophageal symptoms who had a full or partial preoperative AST response experienced lower rates of symptom recurrence compared to patients with poor AST response (P < .01). The rate of symptom recurrence was lowest among patients with primary typical reflux symptoms who had a partial or full symptom response to AST (P < .01). The severity of acid reflux on pH testing, symptom indices, severity of esophagitis, and hiatal hernia size were not associated with symptom response. CONCLUSIONS: In a retrospective study, we found the effectiveness of ARS to be less predictable in patients with extraesophageal symptoms of GERD than in patients with typical GERD. Response to AST before surgery was associated with ARS effectiveness in patients with extraesophageal reflux symptoms. Caution should be exercised when advocating ARS for patients with extraesophageal symptoms that do not respond to AST.

Current trends in the practice of endoscopy among surgeons in the USA.

BACKGROUND: The diagnostic and therapeutic roles for endoscopic intervention are expanding. To continue emphasis on endoscopy in surgical training, The Society of American Gastrointestinal and Endoscopic Surgeons has developed the Fundamentals of Endoscopic Surgery (FES) course to standardize and assess endoscopy training. However, little demographic information exists about the current practice of endoscopy by general surgeons and how to best integrate endoscopic skills into surgical training. METHODS: A survey to collect data regarding the current practice patterns of endoscopy was sent to surgeons with a valid email address in the American Medical Association masterfile. Information regarding the type of training (academic vs. community general surgery residency) and current practice environment (academic medical center vs. community hospital) was collected. The respondents' current practice volume of upper endoscopy and colonoscopy over the prior year was stratified into three groups: rare (<1 per month), moderate (1-10 per month), and frequent (>10 per month). Pearson's Chi-squared test was used to analyze the data. RESULTS: The survey was sent to 9902 general surgeons. There were 767 who provided answers regarding their current practice of endoscopy. Mean time in practice was 18 ± 10 years, 87 % were male, and 83 % practiced in a metropolitan area. Respondents who trained at academic general surgery programs were less likely than those at community programs to frequently perform colonoscopy (17.3 vs. 27.9 %, p < 0.05) and upper endoscopy (11.8 vs. 17.1 %, p < 0.05). Those who currently practice in academic medical centers were also less likely to be frequent performers of colonoscopy (5.6 vs. 24.7 %, p < 0.05) and upper endoscopy (9.8 vs. 14.8 %, p < 0.05) than those who practice at community hospitals. CONCLUSIONS: The type of residency training and current practice setting of general surgeons has a significant influence on the volume of endoscopic procedures performed. This study identifies areas where more emphasis on endoscopic skills training is needed, such as FES.

Cancer Survivorship: Defining the Incidence of Incisional Hernia After Resection for Intra-Abdominal Malignancy.

BACKGROUND: Cancer survivorship focuses largely on improving quality of life. We aimed to determine the rate of ventral incisional hernia (VIH) formation after cancer resection, with implications for survivorship. METHODS: Patients without prior VIH who underwent abdominal malignancy resections at a tertiary center were followed up to 2 years. Patients with a viewable preoperative computed tomography (CT) scan and CT within 2 years postoperatively were included. Primary outcome was postoperative VIH on CT, reviewed by a panel of surgeons uninvolved with the original operation. Factors associated with VIH were determined using Cox proportional hazards regression. RESULTS: 1847 CTs were reviewed among 491 patients (59 % men), with inter-rater reliability 0.85 for the panel. Mean age was 60 ± 12 years; mean follow-up time 13 ± 8 months. VIH occurred in 41 % and differed across diagnoses: urologic/gynecologic (30 %), colorectal (53 %), and all others (56 %) (p < 0.001). Factors associated with VIH (adjusting for stage, age, adjuvant therapy, smoking, and steroid use) included: incision location [flank (ref), midline, hazard ratio (HR) 6.89 (95 %CI 2.43-19.57); periumbilical, HR 6.24 (95 %CI 1.84-21.22); subcostal, HR 4.55 (95 %CI 1.51-13.70)], cancer type [urologic/gynecologic (ref), other {gastrointestinal, pancreatic, hepatobiliary, retroperitoneal, and others} HR 1.86 (95 %CI 1.26-2.73)], laparoscopic-assisted operation [laparoscopic (ref), HR 2.68 (95 %CI 1.44-4.98)], surgical site infection [HR 1.60 (95 %CI 1.08-2.37)], and body mass index [HR 1.06 (95 %CI 1.03-1.08)]. CONCLUSIONS: The rate of VIH after abdominal cancer operations is high. VIH may impact cancer survivorship with pain and need for additional operations. Further studies assessing the impact on QOL and prevention efforts are needed.

Insurance status influences emergent designation in surgical transfers.

BACKGROUND: There is a perception among surgeons that hospitals disproportionately transfer unfavorably insured patients for emergency surgical care. Emergency medical condition (EMC) designation mandates referral center acceptance of patients for whom transfer is requested. We sought to understand whether unfavorably insured patients are more likely to be designated as EMCs. MATERIALS AND METHODS: A retrospective cohort study was performed on patient transfers from a large network of acute care facilities to emergency surgery services at a tertiary referral center from 2009-2013. Insurance was categorized as favorable (commercial or Medicare) or unfavorable (Medicaid or uninsured). The primary outcome, transfer designation as EMC or non-EMC, was evaluated using multivariable logistic regression. A secondary analysis evaluated uninsured patients only. RESULTS: There were 1295 patient transfers in the study period. Twenty percent had unfavorable insurance. Favorably insured patients were older with fewer nonwhite, more comorbidities, greater illness severity, and more likely transferred for care continuity. More unfavorably insured patients were designated as EMCs (90% versus 84%, P < 0.01). In adjusted models, there was no association between unfavorable insurance and EMC transfer (odds ratio [OR], 1.61; 95% confidence interval [CI], 0.98-2.69). Uninsured patients were more likely to be designated as EMCs (OR, 2.27; CI, 1.08-4.77). CONCLUSIONS: The finding that uninsured patients were more likely to be designated as EMCs suggests nonclinical variation that may be mitigated by clearer definitions and increased interfacility coordination to identify patients requiring transfer for EMCs.

Surgeons, ERCP, and laparoscopic common bile duct exploration: do we need a standard approach for common bile duct stones?

BACKGROUND: Variation exists in the management of choledocholithiasis (CDL). This study evaluated associations between demographic and practice-related characteristics and CDL management. METHODS: A 22-item, web-based survey was administered to US general surgeons. Respondents were classified into metropolitan or nonmetropolitan groups by zip code. Univariate tests and multivariable logistic regression were used to determine factors associated with CDL management preferences. RESULTS: The survey was sent to 32,932 surgeons; 9902 performed laparoscopic cholecystectomy within the last year; 750 of 771 respondents had a valid US zip code and were included in the analysis. Mean practice time was 18 ± 10 years, 87% were male, and 83% practiced in a metropolitan area. For preoperatively known CDL, 86% chose preoperative endoscopic retrograde cholangiopancreatography (ERCP). Those in metropolitan areas were more likely to select preoperative ERCP than those in nonmetropolitan areas (88 vs. 79%, p < 0.001). For CDL discovered intraoperatively, 30% selected laparoscopic common bile duct exploration (LCBDE) as their preferred method of management with no difference between metropolitan and nonmetropolitan areas (30 vs. 26%, p = 0.335). The top reasons for not performing LCBDE were: having a reliable ERCP proceduralist available, lack of equipment, and lack of comfort performing LCBDE. Factors associated with preoperative ERCP were: metropolitan status, selective intraoperative cholangiography (IOC), and availability of a reliable ERCP proceduralist. Those who perform selective IOC were 70% less likely to prefer LCBDE (OR 0.32, 95% CI 0.18-0.57, p < 0.001). Those with a reliable ERCP proceduralist available were 90% less likely to prefer LCBDE (OR 0.10, 95% CI 0.04-0.26, p < 0.001). CONCLUSIONS: The majority of respondents preferred ERCP for the management of CDL. Having a reliable ERCP proceduralist available, use of selective IOC, and metropolitan status were independently associated with preoperative ERCP. Postoperative ERCP was preferred for managing intraoperatively discovered CDL. Many surgeons are uncomfortable performing LCBDE, and increased training may be needed.

Addition of a Medial Locking Plate to an In Situ Lateral Locking Plate Results in Healing of Distal Femoral Nonunions.

BACKGROUND: Nonunion of the distal femur after lateral plating is associated with axial malalignment, chronic pain, loss of ambulatory function, and decreased knee ROM. The addition of a medial locking plate with autogenous bone grafting can provide greater stability to allow bone healing and may be used to achieve union in these challenging cases. QUESTIONS/PURPOSES: We wished to determine (1) the proportion of patients who achieve radiographic signs of osseous union for distal femoral nonunions with an in situ lateral plate after treatment with addition of a medial locking plate and autogenous bone grafting, and (2) the frequency and types of complications associated with this treatment. METHODS: Between 2007 and 2013, we treated 22 patients for 23 distal femoral nonunions, defined as an unhealed fracture with no radiographic signs of osseous union at a mean of 16 months (SD, 13 months) after injury. During that time, we used a treatment algorithm consisting of treatment in one or two stages. The single-stage procedure performed in 16 aseptic nonunions with a stable lateral plate involved addition of a medial locking plate and autogenous bone graft. A two-stage treatment performed in seven nonunions with lateral plate failure involved placement of a new lateral locking plate followed by addition of a medial locking plate with autogenous bone graft at least 2 months after the first procedure. Of the 22 patients treated, 20 had a median followup of 18 months (SD, 6-94 months). We defined osseous union by bridging bone on three of four cortices with absence of a radiolucent line or more than 25% cross-sectional area of bridging bone via CT. RESULTS: Twenty of the 21 nonunions attained radiographic signs of osseous union by 12 months. Six of the 20 patients experienced complications: one patient had a persistent nonunion; four patients underwent removal of symptomatic hardware; and one patient experienced skin breakdown at the bone graft harvest site. CONCLUSIONS: A very high proportion of patients achieve union when using medial locking plates to treat distal femoral nonunions after lateral plating of the original injury. Addition of bone graft, staged reconstruction, and revision of the initial lateral plate is indicated when the nonunion is associated with fatigue failure of the initial lateral plate. LEVEL OF EVIDENCE: Level IV, therapeutic study.

Defining intraoperative hypothermia in ventral hernia repair.

BACKGROUND: Intraoperative normothermia, a single measurement of core body temperature≥36°C, is an important quality metric outlined by the World Health Organization for the reduction of surgical site infections (SSIs). Hypothermia has been linked to SSI in colorectal and trauma patients, but the effect in ventral hernia repair (VHR) is unknown. MATERIALS AND METHODS: Patients who underwent VHR at a single institution between 2005 and 2012 were included. Temperature data were matched with National Surgical Quality Improvement Program SSI data. Novel definitions of hypothermia were explored: patient temperature nadir, percentage of time spent at the nadir, mean temperature, and time spent <36°C. Multivariable regression models were performed. RESULTS: Five hundred fifty-three patients were included with temperature recorded every 8-15 min. Mean temperature nadir was 35.7°C (±1.3°C [standard deviation]) and was not associated with SSI (odds ratio [OR], 0.938; 95% confidence interval, 0.778-1.131). The percentage of readings spent at the nadir was 31% (±31%) and was not predictive of SSI (OR, 1.471; 95% CI, 0.983-2.203). As mean temperature increased, the risk of SSI increased (OR, 1.115; 95% CI, 0.559-2.225). Percentage of temperature readings<36°C was 29% (±38%) and was not associated with SSI (OR, 1.062; 95% CI, 0.628-1.796). In all models, body mass index, smoking, and length of surgery were predictive of SSI. CONCLUSIONS: Our results demonstrate no association between temperature and SSI in VHR. Efforts to reduce SSI should focus on factors such as smoking cessation, weight loss, and length of surgery. Our study suggests that maintenance of perioperative normothermia may only decrease SSIs in certain at-risk populations.

Early Acetabular Fracture Repair Through an Anterior Approach Is Associated With Increased Blood Loss.

OBJECTIVES: To determine whether the timing of acetabular fracture fixation through an anterior approach influences estimated and calculated perioperative blood loss. DESIGN: Retrospective cohort study. SETTING: Level 1 trauma center from 2013 to 2021. PATIENT SELECTION CRITERIA: Patients aged ≥18 years treated with acetabular fracture fixation through an anterior-based approach. OUTCOME MEASURES AND COMPARISONS: The primary outcome was calculated blood loss (CBL). Secondary outcomes were estimated blood loss reported by surgeon and anesthesia, and blood transfusion requirements. Comparisons of blood loss were made at discrete postinjury time thresholds (24, 36, and 48 hours) and on a continuous basis. RESULTS: One hundred eight patients were studied. The mean age was 65 years, and 73% of patients were male. Earlier fixation of acetabular fractures resulted in greater CBL and estimated blood loss (surgeon and anesthesia) compared with later fixation when analyzed on a continuum and at specific time points (24, 36, and 48 hours). Mean CBL in patients treated earlier (<48 hours, 2539 ± 1194 mL) was significantly greater than those treated later (≥48 hours, 1625 ± 909 mL; P < 0.001). Fracture repair before 48 hours postinjury was associated with a 3 times greater risk of >2000 mL of CBL ( P = 0.006). This did not result in differences in transfusion rates between groups at 24 hours ( P = 0.518), 36 hours ( P = 1.000), or 48 hours ( P = 0.779). CONCLUSIONS: Delaying fixation of acetabular fractures treated through an anterior approach for 48 hours postinjury may significantly reduce perioperative blood loss. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Effects of Anterior Fundoplication on Postoperative Dysphagia and Reflux After Laparoscopic Esophagocardiomyotomy for Pediatric Achalasia.

Introduction: Achalasia among children often fails endoscopic management (e.g., dilation, botulinum toxin). Laparoscopic esophagocardiomyotomy (L-ECM) is a standard intervention to relieve obstruction but can induce gastroesophageal reflux (GER). Concurrent anterior fundoplication (A-fundo) has been evaluated in randomized trials among adults, demonstrating mixed results on controlling postoperative GER without exacerbating dysphagia. Furthermore, evidence for the best approach among children remains sparse. We hypothesized that, among children undergoing L-ECM without mucosal violation, routine A-fundo would not improve postoperative GER control while exacerbating dysphagia. Materials and Methods: Observational data of 47 consecutive achalasia patients ≤18 years who received L-ECM (2002-2023) at a single academic institution were collected. Patient records were culled for demographics, achalasia characteristics, and outcomes. Two L-ECM groups were identified: with or without A-fundo. Patients were screened for postoperative dysphagia (additional procedures) and GER (new antireflux medications). Univariate independence testing was conducted to identify statistically significant variables. Results: Among 47 patients undergoing L-ECM, 28 (59.6%) received concurrent A-fundo. Compared with patients undergoing L-ECM alone, patients with L-ECM/A-fundo had significantly longer hospital stays (P < .01) without statistically different rates of postoperative dysphagia (P = .81) or GER (P = .51). Five children (10.6%) experienced mucosal injury with L-ECM: 4 recognized intraoperatively received A-Fundo without subsequent leak; 1 mucosal injury was missed and did not receive A-Fundo, which subsequently leaked. Conclusion: In this largest observation of pediatric achalasia patients, A-fundo appeared clinically insignificant when determining contributors to control GER or exacerbate postoperative dysphagia. A-fundo should not be routinely adopted in children having L-ECM for achalasia without further multicenter analysis but appears beneficial in cases having inadvertent mucosal violation.

Disease-based mortality after percutaneous endoscopic gastrostomy: utility of the enterprise data warehouse.

BACKGROUND: Percutaneous endoscopic gastrostomy (PEG) remains a mainstay of enteral access. Thirty-day mortality for PEG has ranged from 16 to 43 %. This study aims to discern patient groups that demonstrate limited survival after PEG placement. The Enterprise Data Warehouse (EDW) concept allows an efficient means of integrating administrative, clinical, and quality-of-life data. On the basis of this concept, we developed the Vanderbilt Procedural Outcomes Database (VPOD) and analyzed these data for evaluation of post-PEG mortality over time. METHODS: Patients were identified using the VPOD from 2008 to 2010 and followed for 1 year after the procedure. Patients were categorized according to common clinical groups for PEG placement: stroke/CNS tumors, neuromuscular disorders, head and neck cancers, other malignancies, trauma, cerebral palsy, gastroparesis, or other indications for PEG. All-cause mortality at 30, 60, 90, 180, and 360 days was determined by linking VPOD information with the Social Security Death Index. Chi-square analysis was used to determine significance across groups. RESULTS: Nine hundred fifty-three patients underwent PEG placement during the study period. Mortality over time (30-, 60-, 90-, 180-, and 360-day mortality) was greatest for patients with malignancies other than head and neck cancer (29, 45, 57, 66, and 72 %) and least for cerebral palsy or patients with gastroparesis (7 % at all time points). Patients with neuromuscular disorders had a similar mortality curve as head and neck cancer patients. Stroke/CNS tumor patients and patients with other indications had the second highest mortality, while trauma patients had low mortality. CONCLUSIONS: PEG mortality was much higher in patients with malignancies other than head and neck cancer compared to previously published rates. PEG should be used with great caution in this and other high-risk patient groups. This study demonstrates the power of an EDW-based database to evaluate large numbers of patients with clinically meaningful results.

Predicting complicated choledocholithiasis.

INTRODUCTION: Management of choledocholithiasis and its complications is variable and often requires transfer to a specialty facility. This study links patient-specific characteristics with the outcome measure of complicated choledocholithiasis to identify high-risk patients who may require expedited treatment or transfer to a higher level of care. MATERIALS AND METHODS: Patients with a discharge diagnosis of choledocholithiasis (CDL) were identified from the 2009 Nationwide Inpatient Sample (NIS). Patient characteristics were identified associated with the primary outcome measure of complicated choledocholithiasis (cCDL), defined as acute pancreatitis or cholangitis during the admission for CDL. Predictors of mortality were also evaluated. Analysis was performed using complex-sample univariate and adjusted analyses. RESULTS: We identified 123,990 discharges with a diagnosis of CDL. The overall incidence of CDL was 314 per 100,000 NIS discharges. Forty-one percent of CDL discharges were for cCDL (acute pancreatitis 31%, cholangitis 12%). Risk factors for cCDL included age (risk increased 0.8% per year), male gender (odds ratio [OR] 1.2, 95% confidence interval [CI] 1.1-1.2), alcohol abuse (OR 1.5, CI 1.3-1.8), diabetes (OR 1.1, CI 1.0-1.2), hypertension (OR 1.1, CI 1.0-1.2), obesity (OR 1.2, CI 1.1-1.3), nonelective admission (OR 2.3, CI 2.0-2.6), and Asian/Pacific Islander race/ethnicity (OR 1.2, CI 1.0-1.5). Patients with cCDL had increased odds of mortality (OR 1.5, CI 1.2-2.0). CONCLUSIONS: Increased age, nonelective admission, and specific comorbid conditions are associated with cCDL, which has increased mortality. These factors can be used to identify patients needing timely access to treatment or transfer to a higher level of care.

An urban-rural blight? Choledocholithiasis presentation and treatment.

BACKGROUND: Exploration of urban-rural (UR) and regional differences is critical to developing effective healthcare delivery systems. Choledocholithiasis (CDL) remains a common problem with a range of therapeutic options and potentially severe complications. This study evaluated UR and regional differences of CDL presentation and treatment. We hypothesized that UR status contributes to differences in treatment of CDL. METHODS: This study examined patients from the 2007 Healthcare Cost and Utilization Project dataset. Inpatient discharges and interventions for CDL patients were identified. UR and regional designations were determined from National Center for Health Statistics guidelines. Patients with pancreatitis or cholangitis were designated as complicated CDL (cCDL) patients. Interventions for CDL were classified as endoscopic, surgical, or percutaneous. Complex-sample proportion analyses were performed. RESULTS: A total of 111,021 patients with CDL were identified; 81% of these patients lived in urban areas compared with 19% in rural areas; 61% had uncomplicated choledocholithiasis (uCDL) and 39% had cCDL. The overall distribution of uCDL and cCDL did not differ by UR status or region. A higher proportion of rural patients did not receive an intervention 45.1% (95%CI 41.8%-48.4%) versus urban patients 30.5% (28.8%-32.2%), P < 0.05. Interventions for urban patients were more likely endoscopic 87.7% (86.8%-88.6%) compared with rural 82.0% (79.3%-84.7%), P < 0.05. Rural patients were more likely to undergo surgery 10.5% (8.6%-12.4%) than urban patients 4.9% (4.4%-5.4%), P < 0.05. Regional variations did not impact the type of intervention received. CONCLUSION: Rural patients received CDL interventions less often and had a higher proportion of surgical interventions regardless of severity of presentation.

Choledocholithiasis management in rural America: health disparity or health opportunity?

BACKGROUND: Choledocholithiasis (CDL) management is dictated by local expertise, individual training, and availability of appropriate staff. This study evaluates the management of CDL between urban and rural communities. MATERIALS AND METHODS: Patients undergoing inpatient management of CDL were identified from the 2007 Healthcare Cost and Utilization Project. Availability of endoscopic retrograde cholangiopancreatography (ERCP) was determined from the 2007 American Hospital Association survey. The proportion of common bile duct exploration (CBDE), ERCP, or percutaneous (PERC) interventions were compared across census regions and National Centers for Health Statistics (NCHS) urban-rural classes. The NCHS urban-rural classification scheme divides counties from most populous (NCHS 1) to rural (NCHS 6). Proportions were compared using the 95% confidence interval (95%CI) approach. RESULTS: We estimated 111,021 CDL hospitalizations in the U.S. in 2007. Of these, 67% had a coded intervention. Intervention frequencies were similar across census regions. Comparisons across NCHS classes revealed higher proportions of ERCP in urban areas (NCHS 1-4) while a higher proportion of CBDE was seen in rural areas (NCHS 5-6). ERCP availability was high in metropolitan areas (available in 35%-44% of hospitals NCHS 1-4) and low in rural areas (25% of NCHS 5 hospitals and 5% NCHS 6). PERC management was similar across NCHS classes. CONCLUSIONS: Rural hospitals and communities need surgeons trained in CBDE, where ERCP expertise may not be readily available. Feasible ways of expanding ERCP coverage to the nation's rural areas need to be explored. These observations may impact surgical training at least for those targeting careers in rural surgery.

Effect of Intrawound Vancomycin Powder in Operatively Treated High-risk Tibia Fractures: A Randomized Clinical Trial.

Importance: Despite the widespread use of systemic antibiotics to prevent infections in surgically treated patients with fracture, high rates of surgical site infection persist. Objective: To examine the effect of intrawound vancomycin powder in reducing deep surgical site infections. Design, Setting, and Participants: This open-label randomized clinical trial enrolled adult patients with an operatively treated tibial plateau or pilon fracture who met the criteria for a high risk of infection from January 1, 2015, through June 30, 2017, with 12 months of follow-up (final follow-up assessments completed in April 2018) at 36 US trauma centers. Interventions: A standard infection prevention protocol with (n = 481) or without (n = 499) 1000 mg of intrawound vancomycin powder. Main Outcomes and Measures: The primary outcome was a deep surgical site infection within 182 days of definitive fracture fixation. A post hoc comparison assessed the treatment effect on gram-positive and gram-negative-only infections. Other secondary outcomes included superficial surgical site infection, nonunion, and wound dehiscence. Results: The analysis included 980 patients (mean [SD] age, 45.7 [13.7] years; 617 [63.0%] male) with 91% of the expected person-time of follow-up for the primary outcome. Within 182 days, deep surgical site infection was observed in 29 of 481 patients in the treatment group and 46 of 499 patients in the control group. The time-to-event estimated probability of deep infection by 182 days was 6.4% in the treatment group and 9.8% in the control group (risk difference, -3.4%; 95% CI, -6.9% to 0.1%; P = .06). A post hoc analysis of the effect of treatment on gram-positive (risk difference, -3.7%; 95% CI, -6.7% to -0.8%; P = .02) and gram-negative-only (risk difference, 0.3%; 95% CI, -1.6% to 2.1%; P = .78) infections found that the effect of vancomycin powder was a result of its reduction in gram-positive infections. Conclusions and Relevance: Among patients with operatively treated tibial articular fractures at a high risk of infection, intrawound vancomycin powder at the time of definitive fracture fixation reduced the risk of a gram-positive deep surgical site infection, consistent with the activity of vancomycin. Trial Registration: ClinicalTrials.gov Identifier: NCT02227446.

Evaluation of Wound Photography for Remote Postoperative Assessment of Surgical Site Infections.

Importance: Surgeons are increasingly interested in using mobile and online applications with wound photography to monitor patients after surgery. Early work using remote care to diagnose surgical site infections (SSIs) demonstrated improved diagnostic accuracy using wound photographs to augment patients' electronic reports of symptoms, but it is unclear whether these findings are reproducible in real-world practice. Objective: To determine how wound photography affects surgeons' abilities to diagnose SSIs in a pragmatic setting. Design, Setting, and Participants: This prospective study compared surgeons' paired assessments of postabdominal surgery case vignettes with vs without wound photography for detection of SSIs. Data for case vignettes were collected prospectively from May 1, 2007, to January 31, 2009, at Erasmus University Medical Center, Rotterdam, the Netherlands, and from July 1, 2015, to February 29, 2016, at Vanderbilt University Medical Center, Nashville, Tennessee. The surgeons were members of the American Medical Association whose self-designated specialty is general, abdominal, colorectal, oncologic, or vascular surgery and who completed internet-based assessments from May 21 to June 10, 2016. Intervention: Surgeons reviewed online clinical vignettes with or without wound photography. Main Outcomes and Measures: Surgeons' diagnostic accuracy, sensitivity, specificity, confidence, and proposed management with respect to SSIs. Results: A total of 523 surgeons (113 women and 410 men; mean [SD] age, 53 [10] years) completed a mean of 2.9 clinical vignettes. For the diagnosis of SSIs, the addition of wound photography did not change accuracy (863 of 1512 [57.1%] without and 878 of 1512 [58.1%] with photographs). Photographs decreased sensitivity (from 0.58 to 0.50) but increased specificity (from 0.56 to 0.63). In 415 of 1512 cases (27.4%), the addition of wound photography changed the surgeons' assessment (215 of 1512 [14.2%] changed from incorrect to correct and 200 of 1512 [13.2%] changed from correct to incorrect). Surgeons reported greater confidence when vignettes included a wound photograph compared with vignettes without a wound photograph, regardless of whether they correctly identified an SSI (median, 8 [interquartile range, 6-9] vs median, 8 [interquartile range, 7-9]; P < .001) but they were more likely to undertriage patients when vignettes included a wound photograph, regardless of whether they correctly identified an SSI. Conclusions and Relevance: In a practical simulation, wound photography increased specificity and surgeon confidence, but worsened sensitivity for detection of SSIs. Remote evaluation of patient-generated wound photographs may not accurately reflect the clinical state of surgical incisions. Effective widespread implementation of remote postoperative assessment with photography may require additional development of tools, participant training, and mechanisms to verify image quality.

Summaries of the SAGES 2007 reoperative minimally invasive surgery symposium.

This manuscript represents a compilation of summaries from the reoperative symposium at the SAGES 2007 conference in Las Vegas, Nevada. The symposium addressed reoperative laparoscopy for several common diseases including colorectal disease, gastroesophageal reflux, hernias, bariatric, and pediatric surgery. The preoperative assessment is crucial to the success of each procedure. Prior to any intervention the underlying functional, mechanical, or pathophysiological disorder must be identified to ensure the success of the reoperative laparoscopic procedure. The ensuing manuscript summarizes the oral presentations and discusses several technical aspects for each disorder.

Optimizing choledocholithiasis management: a cost-effectiveness analysis.

HYPOTHESIS: Endoscopic retrograde cholangiopancreatography (ERCP) is more cost-effective for managing incidental choledocholithiasis (CDL) after laparoscopic cholecystectomy and intraoperative cholangiogram (LC/IOC) than laparoscopic common bile duct exploration (LCBDE). DESIGN: A cost-effectiveness analysis was performed to compare ERCP with LCBDE. Sensitivity analyses were performed to determine the key contributors to cost-effectiveness between the 2 treatment options. SETTING: Costs were approached from the institutional perspective considering a typical patient undergoing LC/IOC at a large referral center. PATIENTS: The base case patient evaluated was a woman 18 years of age or older with symptomatic cholelithiasis and incidental CDL discovered at the time of LC/IOC. INTERVENTIONS: Endoscopic retrograde cholangiopancreatography with drainage procedure performed after LC/IOC or LCBDE during LC/IOC. MAIN OUTCOME MEASURES: Costs, quality-adjusted life years gained, mean cost-effectiveness ratios, and incremental cost-effectiveness ratios. RESULTS: In the base case analysis, ERCP was the optimal treatment choice with a cost of $24 300 for 0.9 quality-adjusted life years gained compared with $28 400 and 0.88 quality-adjusted life years for LCBDE. Endoscopic retrograde cholangiopancreatography remained the optimal strategy for CDL in multiway probabilistic sensitivity analysis. If LCBDE were performed and the cost of a potential operative case lost was $3100 or less and the cost of ERCP hospitalization was $18 000 or more, then LCBDE became the preferred treatment for CDL. CONCLUSIONS: Endoscopic retrograde cholangiopancreatography was both less costly and more effective than LCBDE. Factors important to choosing the best strategy for CDL management included the cost of a potential case lost due to LCBDE performance and the cost of ERCP hospitalization.

Relief of dysphagia after laparoscopic Heller myotomy improves long-term quality of life.

BACKGROUND AND OBJECTIVE: Quality of life (QoL) is getting more attention in the medical literature. Treatment outcomes are now gauged by their effect on the QoL along with their direct effect on the diseases they are targeting. The aim of the study was to assess the impact of residual dysphagia on QoL after laparoscopic Heller myotomy for achalasia. METHODS: QoL was evaluated using the short-form-36 (SF-36) and postoperative dysphagia was assessed using a dysphagia score. The score (range 0-10) was calculated by combining the frequency of dysphagia (0=never, 1 = < 1 day/wk, 2 = 1 day/wk, 3 = 2-3 days/wk, 4 = 4-6 days/wk, 5=daily) with the severity (0=none, 1=very mild, 2=mild, 3=moderate, 4=moderately severe, 5=severe). Patients were classified in the Nonresponder group when their dysphagia score was in the upper quartile. RESULTS: Questionnaires were mailed to 110 patients. The overall response rate was 91% with 100 patients (54 female) returning the questionnaires. The average follow-up was 3.3 years. There was a significative inverse correlation between dysphagia score and mental component (P = 0.0001) and total SF-36 (P = 0.001) scores. According to their postoperative dysphagia scores, 77 patients were assigned to the Responder Group and 23 patients to the Nonresponder Group. The two groups were similar in terms of age, gender, rate of fundoplication, and length of follow-up. Mental component and total SF-36 scores were significantly (P < 0.05) higher in the Responder group. Successful relief of dysphagia after Heller myotomy was associated with health-related quality of life scores that were 13 higher in Vitality (P < 0.05), 11 points higher in mental health (P < 0.05), and 12 points higher in General Health (P < 0.05). Overall patient satisfaction with surgical outcome was 92%, with only eight patients not satisfied with the surgery. CONCLUSION: Laparoscopic Heller myotomy offers excellent long-term relief of achalasia-related symptoms, namely dysphagia, and this was projected on a significant improvement in quality of life and patient satisfaction.

Acute dermal capillary rupture associated with noninvasive blood pressure monitoring.

We report a case of Rumpel-Leede phenomenon, or acute dermis capillary rupture, secondary to noninvasive blood pressure monitoring in a patient with type 2 diabetes mellitus. The most likely cause was increased venous pressure during cycling of the blood pressure cuff during a hypertensive state. Anesthesiologists need to be aware that acute dermal capillary rupture, although rare, can occur in patients with thrombocytopenia and/or long-standing diabetes.
