ABSTRACT

BACKGROUND AND AIM: One of the main causes of mortality among obese patients is cardiovascular disease (CVD). Carotid intima-media thickness (CIMT) is an independent predictor for atherosclerosis and risk of CVD, and has been demonstrated to be related with obesity. This study aimed to evaluate the effect of substantial weight loss after bariatric surgery on CIMT.

METHODS: This prospective study was performed on patients with morbid obesity and standard indications for bariatric surgery in a tertiary referral center in Iran. The mean CIMT values were assessed using B-mode ultrasonography before and 6 months after bariatric surgery.

RESULTS: A total of 32 patients (25 females, 7 males) with a mean age of 38.18 ± 1.18 years were enrolled. Body mass index (BMI) was significantly reduced from 43.66 ± 6.44 to 29.01 ± 2.56 kg/m² during 6 months following surgery (p: 0.001). The mean CIMT values at 6 months after surgery were significantly lower than the baseline (0.53 ± 0.06 vs. 0.50 ± 0.08; p: 0.001). Along with a significant hypertension and metabolic syndrome remission, we observed considerable reduction in FBS (p: 0.019), cholesterol (p: 0.061), triglycerides (p: 0.001), and insulin levels (p: 0.001). Besides, liver stiffness was significantly decreased after surgery (6.15 ± 0.82 vs. 5.26 ± 0.83; p: 0.001). There was no statistically significant correlation between changes in quantitative variables and changes in CIMT.

CONCLUSION: Bariatric surgery results in significant reduction in CIMT, metabolic syndrome factors, and liver stiffness in patients with morbid obesity.

ABSTRACT

BACKGROUND: The Agency for Healthcare Research and Quality uses Patient Safety Indicators (PSI) to gauge quality of care and patient safety in hospitals. PSI 90 is a weighted combination of several PSIs that primarily comprises perioperative events. This score can affect reimbursement through Medicare and hospital quality ratings. Minimally invasive surgery (MIS) has been shown to decrease adverse events and outcomes. We sought to evaluate individual PSI and PSI 90 outcomes of minimally invasive versus open colorectal surgeries using a large medical database from 5 hospitals.

METHODS: A health system administrative database including all inpatients from 5 acute care hospitals was queried based on ICD 10 PC codes for colon and rectal surgery procedures performed between January 2, 2018 and December 31, 2019. Surgeries were labeled as MIS (laparoscopic) or open colorectal resection surgery. Patient demographics, health information, and case characteristics were analyzed with respect to surgical approach and PSI events. Statistical relationships between surgical approach and PSI were investigated using univariate methods and multivariate logarithmic regression analysis. PSIs of interest were PSI 8, PSI 9 PSI 11, PSI 12, and PSI 13.

RESULTS: There were 1382 operations identified, with 861 (62%) being open and 521 (38%) being minimally invasive. Logistic modeling showed no significant difference between the 2 groups for PSI 3, 6, or 8 through 15.

CONCLUSION: Understanding PSI 90 and its components is important to enhance perioperative patient care and optimize reimbursement rates. We showed that MIS, despite providing known clinical benefits, may not affect scores in the PSI 90. Surgical approach may have little effect on PSIs, and other patient and system components that are more important to these outcome measures should be pursued.

ABSTRACT

BACKGROUND: Worldwide, trauma-related deaths are one of the main causes of mortality. Appropriate surgical treatment is crucial to prevent mortality, however, in the past decade, general surgery residents’ exposure to trauma cases has decreased, particularly since the COVID-19 pandemic. In this context, accessible simulation-based training scenarios are essential.

METHODS: A low-cost, previously tested OSCE scenario for the evaluation of surgical skills in trauma was implemented as part of a short training boot camp for residents and recently graduated surgeons. The following stations were included bowel anastomosis, vascular anastomosis, penetrating lung injury, penetrating cardiac injury, and gastric perforation (laparoscopic suturing). A total of 75 participants from 15 different programs were recruited. Each station was videotaped in high definition and assessed in a remote and asynchronous manner. The level of competency was assessed through global and specific rating scales alongside procedural times. Self-confidence to perform the procedure as the leading surgeon was evaluated before and after training.

RESULTS: Statistically significant differences were found in pre-training scores between groups for all stations. The lowest scores were obtained in the cardiac and lung injury stations. After training, participants significantly increased their level of competence in both grading systems. Procedural times for the pulmonary tractotomy, bowel anastomosis, and vascular anastomosis stations increased after training. A significant improvement in self-confidence was shown in all stations.

CONCLUSION: An OSCE scenario for training surgical skills in trauma was effective in improving proficiency level and self-confidence. Low pre-training scores and level of confidence in the cardiac and lung injury stations represent a deficit in residency programs that should be addressed. The incorporation of simulation-based teaching tools at early stages in residency would be beneficial when future surgeons face extremely severe trauma scenarios.

ABSTRACT

OBJECTIVE: The aim of this study was to evaluate the clinical outcome of sphenoid wing meningioma with periorbital invasion (PI) after operation.

METHODS: Sixty one patients with sphenoid wing meningioma were enrolled in this study. Their clinical conditions were monitored after the operation and followed up more than 5 years at the outpatient clinic of a single institution. Clinical and radiologic information of the patients were all recorded including the following parameters : presence of PI, presence of peri-tumor structure invasion, pathologic grade, extents of resection, presence of hyperostosis, exophthalmos index (EI), and surgical complications. We compared the above clinical parameters of the patients with sphenoid wing meningioma in the presence or absence of PI (non-PI), then linked the analyzed data with the clinical outcome of the patients.

RESULTS: Of 61 cases, there were 14 PI and 47 non-PI patients. PI group showed a significantly higher score of EI (1.37±0.24 vs. 1.00±0.01, p<0.001), more frequent presence of hyperostosis (85.7% vs. 14.3%, p<0.001), and lower rate of gross total resection (GTR) (35.7% vs. 68.1%, p=0.032). The lower score of pre-operative EI, the absence of both PI and hyperostosis, smaller tumor size, and the performance of GTR were associated with lower recurrence rates in the univariate analysis. However, in the multivariate analysis, the performance of GTR was the only significant factor to determine the recurrence rate (p=0.043). The incidences of surgical complications were not statistically different between the subtotal resection (STR) and GTR groups, but it was strongly associated tumor size (p=0.017).

CONCLUSION: The GTR group showed lower recurrence rate than the STR group without differences in the surgical complications. Therefore, the GTR is strongly recommended to treat sphenoid wing meningioma with PI for the better clinical outcome.

ABSTRACT

INTRODUCTION: Surgery is widely accepted today when downstaging of mediastinal lymph nodes after neoadjuvant therapy is achieved. However, the role of surgery in patients with persistent N2 disease is still controversial. This study aims to detail the diagnostic problems, prognostic features, and long-term survival of the persistent N2 non-small cell lung cancer patient group.

PATIENTS AND METHODS: One-hundred fifty patients who received neoadjuvant therapy and subsequently underwent resection, in-between 2003 and 2015, were retrospectively analyzed. In this study, “persistent N2” group refers to patients who received neoadjuvant therapy for clinically or histologically proven N2, who underwent a surgery after having been classified as “downstaged” at restaging, but in whom ypN2 lesions were subsequently confirmed on the operative specimens. Patients with multistation N2 were included in the study. There were 119 patients who met the criteria, whereas persistent ypN2 was detected in 28.5% (n = 34) of all patients.

RESULTS: Overall 5-year survival rate was 47.2%, while it was 23.4% for patients with persistent N2. Factors that adversely affected survival were to have nonsquamous cell histological type (p = 0.006), high ypT stage (p = 0.001), persistent N2 (p = 0.02), and recurrence during follow-up (p < 0.001). A trend toward a shorter survival was observed when the ypN2 zone was subcarinal versus other zones, but did not reach statistical significance (p = 0.08). In addition, a trend toward a shorter survival of patients with multiple N2 involvement (p = 0.412) was observed.

CONCLUSION: In the persistent N2 group, when multiple involvement or subcarinal involvement was excluded, relatively good survival was detected.

ABSTRACT

OBJECTIVE: The aim of this clinical study was to determine whether the telemetric BioHarness 3.0^TMchest strap (Zephyr Technology, Medtronic, Annapolis, USA), designed for use in humans and specialized for heart rate variability (HRV) analysis, could be used to accurately measure Heart Rate Variability (HRV) in pigs.

METHODS: The R-wave intervals (RR-intervals) of the BioHarness 3.0^TM electrocardiogram (ECG) were compared with those of the widely used telemetric ECG Televet^®100 device (Engel Engineering GmbH, Heusenstamm, Germany). Measurements were performed under general anesthesia, to ensure continuous data collection due to the risk of detachment in adhesive electrodes of the Televet^®100. The 2 devices were started simultaneously and measurements were taken 6 times in a row for 5 minutes, respectively. The data were collected from 5 male growing pigs. Following artifact correction resp. deletion 5321 RR paired data within a 3 digit range (ms) were analyzed statistically.

RESULTS: The Lin Concordance-Correlation-Analysis after Lin (correlation coefficient 0.95), and the Bland-Altman-Analysis (RR distance differences + 0.3 ms) demonstrated a very good measurement compliance.

CONCLUSION: This data suggests the BioHarness chest strap may be used for wireless HRV analysis in pigs as was shown in a follow up study in non-anesthetized pigs.

ABSTRACT

PURPOSE: In order to prevent implant failure and secondary fracture dislocation, it is often recommended that patients perform partial weight-bearing after surgery of the lower extremity. Previous examinations showed that patients are often not able to follow these instructions. In this study, patients who had undergone surgery of the lower extremity were studied in order to analyze whether incorrect loading influenced the number and severity of complications.

METHODS: Fifty-one patients were equipped with electronic shoe insoles, which measure loading and other parameters. The measurement period was 24 to 102 hours. Median duration of follow-up was 490 days. The primary outcome parameter was postoperative complications leading to revision surgery. Statistical analysis was performed using the chi-square and Fisher exact tests with significance set at a p < 0.05.

RESULTS: Seven out of fifty-one patients had postoperative complications. Four wound complications, one implant failure, chronic instability after fracture of the tibia, and one implant loosening of a hip prosthesis were recorded. In total, 26 of 39 patients were not able to follow the postoperative instructions. Five of the twenty-six patients with difficulties in partial weight-bearing suffered a postoperative complication. In comparison, only 2 of the other 25 patients were affected. There was no statistically significant correlation between high weight-bearing and occurrence of complications (p = 0.29).

CONCLUSION: Most of the patients were unable to follow the surgeon’s instructions for partial weight-bearing. Excessive loading did not seem to influence the number and severity of postoperative complications, especially regarding implant failure. Therefore, we should continue with measurements and reevaluate the “partial weight-bearing doctrine”.

ABSTRACT

BACKGROUND: In sophisticated surgical procedures, e. g. colectomy, cardiac surgery, arterial reconstruction and liver resection, the individual surgeon is a major influence on postoperative morbidity. For the everyday procedure of cholecystectomy, clear data on the morbidity related to the individual surgeon are lacking.

AIMS: To assess the individual impact on the outcome of cholecystectomy in a cohort of experienced surgeons.

METHODS: The analysis covered n = 710 consecutive patients who had received cholecystecomy between January 2014 and December 2018 – performed by experienced surgeons (> n = 300 cholecystectomies before entry in the study and > 5 years after specialty registration). In a univariate analysis, the influence of patient characteristics, laboratory findings and surgical data on postoperative morbidity were investigated. Variables with statistical significance were entered into a multivariate logistic regression.

RESULTS: Mortality was 5/710 (0.7%), and morbidity was 58/710 (8.2%), including 37/710 patients with surgical morbidity and 21/710 patients with non-surgical morbidity. In a multivariable analysis the independent risk factors for overall morbidity were creatinine level (OR 1.29, CI 1.01-1.648, p = 0.042), GOT (OR 1.005, CI 1-1.01, p = 0.03), open/conversion surgery (OR 4.134, CI 1.587-10.768, p = 0.004) and the individual surgeon (OR up to 40.675, p = 0.001). In the analysis of surgical complications, open/conversion surgery (OR 8.104, CI 3.03-21.68, p < 0.001) and the individual surgeon (OR up to 79.69, p = 0.005) remained of significant influence.

CONCLUSIONS: The individual surgeon is of major influence on the outcome after an everyday procedure such as cholecystectomy in a group of experienced surgeons with specialty registration. The individual outcome of each surgeon should be measured as a basis of targeted improvement programs.

PURPOSE: Although pharmacist-provided diabetes services have been shown to be effective, the effectiveness of telepharmacy (TP) in diabetes management has not been clearly established. This systematic review and meta-analysis aims to evaluate the effectiveness of diabetes TP services.

METHODS: PubMed, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched (from inception through September 2021) to identify published studies that evaluated the effect of TP services in patients with diabetes mellitus and reported either glycosylated hemoglobin (HbA1c) or fasting blood glucose (FBG) outcomes. Mean difference (MD), weighted mean difference (WMD), relative risk (RR), and 95% confidence intervals were calculated using the DerSimonian and Laird random-effects model.

RESULTS: 36 studies involving 13,773 patients were included in the systematic review, and 23 studies were included in the meta-analysis. TP was associated with a statistically significant decrease in HbA1c (MD, -1.26%; 95% CI, -1.69 to -0.84) from baseline. FBG was not significantly affected (MD, -25.32 mg/dL; 95% CI, -57.62 to 6.98). Compared to non-TP service, TP was associated with a lower risk of hypoglycemia (RR, 0.48; 95% CI, 0.30-0.76). In a subset of studies that compared TP to face-to-face (FTF) pharmacy services, no significant difference in HbA1c lowering was seen between the 2 groups (WMD, -0.09%; 95% CI, -1.07 to 0.90).

CONCLUSION: Use of TP was associated with reduction of HbA1c and the risk of hypoglycemia in patients with diabetes mellitus. High-quality randomized controlled trials are needed to validate the effectiveness of diabetes TP services relative to FTF services.

ABSTRACT

BACKGROUND: Gastric transposition (GT) is a possible option for esophageal replacement in long-gap esophageal atresia (LGEA). The present study aims to report and compare indications and outcome of laparoscopic-assisted GT (LAGT) versus open (OGT) GT for LGEA repair.

METHODS: Retrospective single-center analysis of all LGEA patients undergoing GT between 2002 and 2021.

RESULTS: Thirty-one children with LGEA underwent GT. Of these, 19 underwent LAGT (mean weight at surgery 5.6 kg; mean age 167 days) and 12 underwent OGT (6.1 kg; 233 days). Indications for OGT were previous surgery (n = 7), associated severe cardiac malformations (n = 4), and a simultaneous resection of a choledochal cyst (n = 1). The conversion rate was 1. The two procedures (LAGT/OGT) differed in anesthetic time (308/350 min), duration of ventilation (5.1/5.3 days), hospital stay (34/32 days), and complications (22/15). None of the differences reached statistical significance. Outcome was also comparable: completely oral nutrition uptake in 66%/73%, slow weight gain in the low centiles in both groups, no patient developed dumping syndrome, symptomatic reflux was seen in 1 patient after OGT.

CONCLUSION: In our cohort, LAGT for repair of LGEA provided similar outcomes as open surgery. The minimally invasive approach preserves thoracal structures, prevents additional thoracotomy or laparotomy, and is faster. To realize LAGT, a postpartal treatment concept including gastrostomy placement via a microincision to minimize adhesions is essential. The open surgical approach should be considered in cases of previous extensive surgical attempts of EA correction causing severe adhesions as well as associated anomalies or genetic syndromes causing hemodynamic instability.
