Chest X-ray for predicting mortality and the need for ventilatory support in COVID-19 patients presenting to the emergency department.

OBJECTIVES: To evaluate the inter-rater agreement of chest X-ray (CXR) findings in coronavirus disease 2019 (COVID-19) and to determine the value of initial CXR along with demographic, clinical, and laboratory data at emergency department (ED) presentation for predicting mortality and the need for ventilatory support. METHODS: A total of 340 COVID-19 patients who underwent CXR in the ED setting (March 1-13, 2020) were retrospectively included. Two reviewers independently assessed CXR abnormalities, including ground-glass opacities (GGOs) and consolidation. Two scoring systems (Brixia score and percentage of lung involvement) were applied. Inter-rater agreement was assessed by weighted Cohen's kappa (κ) or intraclass correlation coefficient (ICC). Predictors of death and respiratory support were identified by logistic or Poisson regression. RESULTS: GGO admixed with consolidation (n = 235, 69%) was the most common CXR finding. The inter-rater agreement was almost perfect for type of parenchymal opacity (κ = 0.90), Brixia score (ICC = 0.91), and percentage of lung involvement (ICC = 0.95). The Brixia score (OR: 1.19; 95% CI: 1.06, 1.34; p = 0.003), age (OR: 1.16; 95% CI: 1.11, 1.22; p < 0.001), PaO2/FiO2 ratio (OR: 0.99; 95% CI: 0.98, 1; p = 0.002), and cardiovascular diseases (OR: 3.21; 95% CI: 1.28, 8.39; p = 0.014) predicted death. Percentage of lung involvement (OR: 1.02; 95% CI: 1.01, 1.03; p = 0.001) and PaO2/FiO2 ratio (OR: 0.99; 95% CI: 0.99, 1.00; p < 0.001) were significant predictors of the need for ventilatory support. CONCLUSIONS: CXR is a reproducible tool for assessing COVID-19 and integrates with patient history, PaO2/FiO2 ratio, and SpO2 values to early predict mortality and the need for ventilatory support. KEY POINTS: • Chest X-ray is a reproducible tool for assessing COVID-19 pneumonia. • The Brixia score and percentage of lung involvement on chest X-ray integrate with patient history, PaO2/FIO2 ratio, and SpO2 values to early predict mortality and the need for ventilatory support in COVID-19 patients presenting to the emergency department.

Reiki and related therapies in the dialysis ward: an evidence-based and ethical discussion to debate if these complementary and alternative medicines are welcomed or banned.

BACKGROUND: Complementary and Alternative Medicines (CAMs) are increasingly practiced in the general population; it is estimated that over 30% of patients with chronic diseases use CAMs on a regular basis. CAMs are also used in hospital settings, suggesting a growing interest in individualized therapies. One potential field of interest is pain, frequently reported by dialysis patients, and seldom sufficiently relieved by mainstream therapies. Gentle-touch therapies and Reiki (an energy based touch therapy) are widely used in the western population as pain relievers.By integrating evidence based approaches and providing ethical discussion, this debate discusses the pros and cons of CAMs in the dialysis ward, and whether such approaches should be welcomed or banned. DISCUSSION: In spite of the wide use of CAMs in the general population, few studies deal with the pros and cons of an integration of mainstream medicine and CAMs in dialysis patients; one paper only regarded the use of Reiki and related practices. Widening the search to chronic pain, Reiki and related practices, 419 articles were found on Medline and 6 were selected (1 Cochrane review and 5 RCTs updating the Cochrane review). According to the EBM approach, Reiki allows a statistically significant but very low-grade pain reduction without specific side effects. Gentle-touch therapy and Reiki are thus good examples of approaches in which controversial efficacy has to be balanced against no known side effect, frequent free availability (volunteer non-profit associations) and easy integration with any other pharmacological or non pharmacological therapy. While a classical evidence-based approach, showing low-grade efficacy, is likely to lead to a negative attitude towards the use of Reiki in the dialysis ward, the ethical discussion, analyzing beneficium (efficacy) together with non maleficium (side effects), justice (cost, availability and integration with mainstream therapies) and autonomy (patients' choice) is likely to lead to a permissive-positive attitude. SUMMARY: This paper debates the current evidence on Reiki and related techniques as pain-relievers in an ethical framework, and suggests that physicians may wish to consider efficacy but also side effects, contextualization (availability and costs) and patient's requests, according also to the suggestions of the Society for Integrative Oncology (tolerate, control efficacy and side effects).

Laparoscopic repair of wound defects in the elderly: our experience of 5 years.

BACKGROUND: Laparoscopic approach for wound defects is a procedure that aims to reduce surgical aggressiveness against the abdominal wall by using minimal incisions and dedicated instruments. METHODS: We report our experience about clinical outcome of elderly patients undergoing laparoscopic repair for incisional hernias (Group I) and primary inguinal hernias (Group II) from June 2007 to September 2012. RESULTS AND DISCUSSION: In our experience there was no significant difference in laparoscopic procedure between normalweight and overweight patients. CONCLUSIONS: Laparoscopic repair for primary inguinal hernias and incisional ventral hernias with transabdominal placement of composite mesh in the elderly achieves excellent results with lower morbidity in comparison with open surgical approaches.

Transabdominal pre-peritoneal mesh in inguinal hernia repair in elderly: end point of our experience.

BACKGROUND: Aim of this study is to present our standardized laparoscopic transabdominal preperitoneal hernia repair (TAPP) technique, and to study our experience in the elderly as far as concerns preoperative and postoperative variables. METHODS: We described our standardized TAPP technique according with Stuttgart technique 1, and we evalutated our team's experience in TAPP inguinal hernia repair in elderly (> 65 yrs) and in young patients (< 65 yrs). RESULTS: We retrospectively reviewed our Surgery Division's experience about TAPP; we included in our study 185 patients. The sample was subdivided in two groups: TAPP Group (< 65 years patients) and TAPPe Group (> 65 years patients). TAPP Group was composed by 154 patients and TAPPe Group of 31 patients. According with literature, in this subgroup recurrence rate (3,2%), early and delayed complications and mean operative time (86 min). There were no major vascular or intestinal complications. At the moment follow-up is 31 months. There were no incisional hernias on umbilical trocar. Mean satisfaction rate was excellent also in elderly patients. CONCLUSIONS: According with literature, in our experience TAPP technique is a safe and feasible procedure, even in elderly patients.

Can We Apply Snyder's Arthroscopic Classification to Ultrasound for Evaluating Rotator Cuff Tears? A Comparative Study with MR Arthrography.

We aimed to demonstrate the applicability of Snyder's arthroscopic classification of rotator cuff tears (RCT) in shoulder ultrasound (US) and to compare it with MR arthrography (MRA). Forty-six patients (34 males; mean age:34 ± 14 years) underwent shoulder US and MRA. Two radiologists (R1 = 25 years of experience; R2 = 2 years of experience) assigned A1-4, B1-4, or C1-4 values depending on the extent of RCT in both US and MRA. Inter-reader intra-modality and intra-reader inter-modality agreement were calculated using Cohen's kappa coefficient. US sensitivity and specificity of both readers were calculated using MRA as the gold standard. Patients were divided into intact cuff vs. tears, mild (A1/B1) vs. moderate (A2-3/B2-3) tears, mild-moderate (A2/B2) vs. high-moderate (A3/B3) cuff tears, moderate (A2-3/B2-3) vs. advanced (A4/B4) and full-thickness (C) tears. The highest agreement values in inter-reader US evaluation were observed for mild-moderate vs. high-moderate RCT (K = 0.745), in inter-reader MRA evaluation for mild vs. moderate RCT (K = 0.821), in R1 inter-modality (US-MRA) for mild-moderate vs. high-moderate and moderate vs. advanced/full-thickness RCT (K = 1.000), in R2 inter-modality (US-MRA) for moderate vs. advanced/full-thickness RCT (K = 1.000). US sensitivity ranged from 88.89%(R1)-84.62%(R2) to 100% (both readers), while specificity from 77.78%(R1)-90.00%(R2) to 100% (both readers). Snyder's classification can be used in US to ensure the correct detection and characterization of RCT.

Adherence to Quality Indicators for Breast Cancer Management in a Multidisciplinary Training Program.

Background: The management of early breast cancer (BC) needs supervision and skill maintenance, and should be performed by specialists working as a team in multidisciplinary breast units. This approach aims to improve the long-term survival and quality of life of patients with BC. Methods: This was a prospective observational study including patients newly diagnosed with operable BC. The study encompassed the pre-surgical phase, throughout the diagnostic and surgical workout, and included post-therapeutic master multidisciplinary team meetings (MTMs) sessions, between 2019 and 2022. Results: We enrolled 280 patients with BC from eight breast units. The Senonetwork indicators regarding diagnosis, waiting time, loco-regional treatment, and adjuvant therapy were collected for each patient discussed. Conclusions: Overall, the majority of quality indicators were respected among breast units. The most critical issue referred to timing indicators: more than 30 days from MTM to surgery, more than 42 days from diagnosis to surgery, and more than 60 days from the first screening mammogram to surgery for many patients. Some aspects of the histopathological diagnosis of intraductal BC also need to be improved. Furthermore, other critical issues in our study regarded some aesthetical indicators, demonstrating low interest in these essential quality indicators.

Risk of unexpected uterine leiomyosarcoma during laparoscopic procedures: Experience from a single tertiary institute in Italy.

OBJECTIVE: To evaluate the incidence of occult uterine sarcomas and investigate whether an accurate and well-established preoperative assessment for uterine fibroids could help identify uterine sarcomas more effectively. METHODS: A retrospective analysis of patients who underwent gynecological laparoscopic surgery for presumed uterine fibroids at Sant'Anna Hospital, a single tertiary institute in Turin, Italy, between January 2003 and December 2019. RESULTS: Over the 17-year period, 5826 laparoscopic surgical procedures (myomectomies or subtotal/total hysterectomies) were performed for presumed uterine fibroids. A total of 48 patients with a final diagnosis of uterine sarcoma were identified, the majority of which (n = 39; 81.3%) were recognized as suspicious uterine sarcomas during the preoperative assessment, and morcellement was avoided. The occurrence of unexpected uterine sarcomas was 0.1% (6/5826). Morcellation was conducted in one patient with uterine sarcoma. CONCLUSION: Analysis of our data showed that unexpected uterine sarcomas are uncommon. Accurate preoperative evaluation can help avoid, but does not exclude, the possibility of morcellation of unknown uterine sarcomas.

Neoadjuvant Chemotherapy Prior Fertility-Sparing Surgery in Women with FIGO 2018 Stage IB2 Cervical Cancer: A Systematic Review.

Nowadays, the optimal management of patients with cervical cancers measuring 2-4 cm desiring to maintain fertility is still uncertain. In this systematic review, we assessed the reliability of neoadjuvant chemotherapy (NACT) prior to fertility-sparing (FS) surgery in International Federation of Gynecology and Obstetrics (FIGO) 2018 stage IB2 cervical cancer, in terms of pathologic response, oncological and obstetric outcomes. The review of the literature was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Data, using MEDLINE and PubMed, were searched for from 1 January 2005 up to 1 December 2020. We identified 20 articles and 114 women with IB2 disease, possible candidates for NACT prior to FS surgery. However, uterine conservation was achieved only in 76.7% of them. Patients reached optimal pathological response to NACT in 60.9% of cases and a TIP (cisplatin, ifosfamide and paclitaxel) regime was related to the best response. Suboptimal response to NACT appeared to be an independent negative prognostic factor. Up to 9.2% of patients recurred with a median 7.4-months DFS, and 4.6% of patients died of disease. Fifty percent of women tried to conceive after treatment and NACT prior to conization appeared to be the most promising alternative to upfront radical trachelectomy in terms of obstetric outcomes. In conclusion, NACT prior to FS surgery is an option, but the literature about this issue is still weak and FS should be carefully discussed with patients.

Low-Pressure Laparoscopy Using the AirSeal System versus Standard Insufflation in Early-Stage Endometrial Cancer: A Multicenter, Retrospective Study (ARIEL Study).

The aim of our study was to evaluate the benefits of a low-pressure insufflation system (AirSeal) vs. a standard insufflation system in terms of anesthesiologists' parameters and postoperative pain in patients undergoing laparoscopic surgery for early-stage endometrial cancer. This retrospective study involved five tertiary centers and included 152 patients with apparent early-stage disease who underwent laparoscopic surgical staging with either the low-pressure AirSeal system (8−10 mmHg, n = 84) or standard laparoscopic insufflation (10−12 mmHg, n = 68). All the intraoperative anesthesia variables evaluated (systolic blood pressure, end-tidal CO2, peak airway pressure) were significantly lower in the AirSeal group. We recorded a statistically significant difference between the two groups in the median NRS scores for global pain recorded at 4, 8, and 24 h, and for overall shoulder pain after surgery. Significantly more women in the AirSeal group were also discharged on day one compared to the standard group. All such results were confirmed when analyzing the subgroup of women with a BMI >30 kg/m2. In conclusion, according to our preliminary study, low-pressure laparoscopy represents a valid alternative to standard laparoscopy and could facilitate the development of outpatient surgery.

Shoulder Magnetic Resonance Arthrography with the Internal and External Rotation Positions of the Humeral Head in the Evaluation of SLAP Lesions.

We aimed to evaluate the diagnostic performance of shoulder MR arthrography (MRA) acquired in the neutral (N), internal rotation (IR), and external rotation (ER) positions of the shoulder to detect SLAP lesions. Three observers evaluated 130 MRAs to detect SLAP lesions and to calculate labral diastasis in this triple-blinded study. Sensitivity was much higher in the ER (92.5-97.5%) than in the N (60-72.5%) and IR (42.5-52.5%) positions, and the specificity of all the reviewers was 100% in all the positions. The diagnostic accuracy was higher in the ER too (97.7-99.2%). The diastasis length was significantly higher in the ER (median = 2.5-2.8 mm) than in the N (1 mm) and IR (0 mm) positions and was also significantly higher in those patients requiring surgery (p = 0.001). The highest inter-rater agreement values were observed in the ER both in SLAP detection (k = 0.982) and the diastasis length evaluation (ICC = 0.962). The diastasis length threshold in the ER that best separated the patients who did and did not require surgery was 3.1 mm (AUC = 0.833). In 14.6% of the cases, ER enabled the detection of SLAP lesions not identified in the N position. MRA with the ER improves the diagnosis of SLAP lesions and, together with the IR position, provides additional dynamic information about the diastasis of the lesions. It is recommended to perform additional ER and IR scans in the shoulder MRA protocol.

Oncophone20 study: Patients' perception of telemedicine in the COVID-19 pandemic during follow-up visits for gynecological and breast cancers.

OBJECTIVE: To analyze oncological patients' perception of telemedicine during the COVID-19 pandemic. METHODS: A total of 345 women, of whom 267 experienced breast cancer and 78 experienced a gynecological cancer, were enrolled. Specific questionnaires about their experiences and feelings about telemedicine in the COVID-19 era were collected. RESULTS: In the breast group, "enhanced care" showed moderate positive perception (mean 4.40) among less-educated women that was slightly lower among better-educated women (mean 4.14) with a significant difference (P = 0.034). "satisfaction" had an opposite pattern: a mean of 3.99 for a lower level of education and 4.78 for a higher level of education, with a strong significant difference (P < 0.001). "privacy and discomfort" approached neutrality for less-educated women, while for higher-educated women the lower mean of 2.93 indicted a more positive perception (P = 0.007). In the pelvic group, younger women had a better perception towards telemedicine for "telemedicine as a substitution" (mean 3.68) compared to older women (mean 3.05). The privacy and discomfort subscale was in favor of better-educated women (mean 2.57) compared to less-educated women (mean 3.28; P = 0.042). CONCLUSION: Telemedicine was generally well accepted, not only among younger and higher-educated women but also by women needing intensive care, in both cancer groups.

Post-discharge chest CT findings and pulmonary function tests in severe COVID-19 patients.

PURPOSE: To evaluate chest computed tomography (CT) and pulmonary function test (PFT) findings in severe COVID-19 patients after discharge and correlate CT pulmonary involvement with PFT results. METHODS: COVID-19 patients admitted to our hospital between February 25 and May 2, 2020, were retrospectively included according to the following criteria: (a) COVID-19 defined as severe based on the WHO interim guidance (i.e., clinical signs of pneumonia plus respiratory rate > 30 breaths/min, severe respiratory distress, and/or SpO2 < 90 % on room air); (b) chest radiograph in the acute setting; (c) post-discharge unenhanced chest CT; and (d) post-discharge comprehensive PFT. Imaging findings were retrospectively evaluated in consensus by two readers, and volume of abnormal lung was measured on CT using 3D Slicer software. Differences between demographics, comorbidities, acute radiographic findings, PFT, and post-discharge clinical and laboratory data of patients with normal and abnormal CT findings were assessed by Mann-Whitney or Fisher tests, and the compromised lung volume-PFT association by Pearson correlation after removing possible outliers. RESULTS: At a median of 105 days from symptom onset, 74/91 (81 %) patients had CT abnormalities. The most common CT pattern was combined ground-glass opacity and reticular pattern (46/74, 62 %) along with architectural distortion (68/74, 92 %) and bronchial dilatation (66/74, 89 %). Compromised lung volume had a median value of 15 % [11-23], was higher in dyspneic patients, and negatively correlated with the percentage of predicted DLCO, VA, and FVC values (r = -0.39, -0.5, and -0.42, respectively). These PFT parameters were significantly lower in patients with CT abnormalities. Impairment of DLCO and KCO was found in 12 (13 %) cases, possibly implying an underlying pulmonary vasculopathy in this subgroup of patients. CONCLUSIONS: Most severe COVID-19 survivors still had physiologically relevant CT abnormalities about three months after the disease onset, with an impairment of diffusion capacity on PFT. A pulmonary vasculopathy was suggested in a minor proportion of patients.

A rare case of ovarian adenomyoma mimicking primary invasive ovarian cancer with a contralateral serous borderline ovarian tumor: A case report and review of the literature.

Extrauterine adenomyoma is a rare type of benign tumor, characterized by nodular aggregate of smooth muscle, endometrial glands and endometrial stroma, arising outside the uterus. In this study we describe a case of primary ovarian adenomyoma associated with endometriotic cysts with contralateral serous borderline tumor in a 40-year-old woman and we highlight how preoperative exams could lead to the suspicious of invasive cancer. We provide a review of the literature, analyzing all cases of extrauterine adenomyoma published so far, classifying them on the basis of pathogenetic theories proposed, localization of the lesion, imaging modalities and treatment adopted.

Pseudoangiomatous Stromal Hyperplasia (PASH) of the Breast: An Uncommon Finding in an Uncommon Patient.

BACKGROUND Pseudoangiomatous stromal hyperplasia (PASH) is an uncommon benign breast lesion. CASE REPORT PASH is reported in a young female in treatment for neurological diseases with multi-drug therapy (clonazepam, valproate and risperidone). Her menstrual cycles are irregular, and she reached menarche very late. CONCLUSIONS The higher PASH prevalence in premenopausal woman (the majority of whom are actively taking oral contraceptive pills), in 24% to 47% of men with gynecomastia and during pregnancy supports a hormonal etiology; the interaction between clonazepam, valproate, risperidone and progesterone could increase the level of progesterone that could stimulate PASH growth.

Role of Magnetic Resonance Imaging in the Evaluation of Breast Cancer Response to Neoadjuvant Chemotherapy.

BACKGROUND/AIM: The aim of the study was to evaluate whether residual tumor assessment by magnetic resonance imaging (MRI) after neoadjuvant chemotherapy (NACT) is fundamental for a successive surgical strategy. PATIENTS AND METHODS: We collected 55 MRIs performed after NACT. RESULTS: Pathological response rate was 20%. MRI's sensitivity, specificity, PPV and NPV were 50%, 88%, 54% and 86%, respectively. We observed a high variability between the different subgroups, with high number of false positives in luminal A/B tumors. Triple negative and HER2+ tumors had almost the same specificity and sensitivity (81% and 50%). Nevertheless, in the HER2+ group, PPV was greater than that in the triple negative group (71% and 33% respectively) and the NPV of the triple negative group was greater than that of the HER2+ one (90% and 64%, respectively). Statistical analysis showed a weak but significant correlation between MRI and pathological assessment of residual tumor dimension. CONCLUSION: The present study, confirms literature data about MRI accuracy in diagnosing HER2+ and triple negative tumors, but suggests caution in case of luminal tumors' evaluation.

Vacuum intraoperative specimen mammography: A novel technique.

OBJECTIVE: Intraoperative specimen mammography (ISM) is a diffuse technique that allows surgeons to check specimens immediately after lumpectomy. Although the specimen is slightly compressed, the radiological image can be distorted by tissue overlap, and this may affect the evaluation of tumour borders, resulting in extension of the lumpectomy. As ISM may be less precise due to inadequate compression, a vacuum effect was applied to the specimen to increase the precision of margin detection. STUDY DESIGN: This study was conducted at St. Anna Hospital Breast Unit, Turin, Italy. Women who underwent lumpectomy for cancer were eligible for inclusion. Both standard ISM (sISM) and vacuum ISM (vISM) were performed. Eighteen specimens obtained after lumpectomy from 1 April 2018 to 31 April 2018 were scanned. sISM (two orthogonal projections) was performed. Next, the specimen was placed in a vacuum, and vISM was performed. The examination was completed with a second orthogonal projection after removal of the vacuum, replacement of the specimen and repositioning of the vacuum. Additional tissue was removed if the surgeon considered that excision was inadequate. Finally, the specimen was sent for definitive histopathological analysis, which is the gold standard for the assessment of surgical margins. Intraoperative histological margin assessment was not performed. The sISM and vISM images and final histopathology reports were compared. RESULTS: For sISM, specificity was 47 % [95 % confidence interval (CI) 25-70], sensitivity was 67 % (95 % CI 21-94), positive predictive value (PPV) was 20 % (95 % CI 6-51) and negative predictive value (NPV) was 88 % (95 % CI 53-98). For vISM, specificity was 100 % (95 % CI 80-100), sensitivity was 67 % (95 % CI 21-94), PPV was 100 % (95 % CI 34-100) and NPV was 94 % (95 % CI 72-99). CONCLUSION: These data suggest that the vacuum technique is feasible, cost-saving and yields results that are similar to those from frozen sections but without the limitations, such as prolonged operating time, high variability in sensitivity due to pathologists' abilities, risk of compromising the histological report, and unreliability for small lumps and ductal carcinoma in situ.

Tracheal diverticula: A retrospective analysis of patients referred for thoracic CT.

To assess the prevalence of tracheal diverticula (TD) in patients referred for thoracic Computed Tomography (CT).1679 consecutive patients subjected to thoracic CT examination for different causes, from January to June 2017, were included in this cohort study. CT was performed with a 64 slice CT, using a standard protocol and Multiplanar Reformat Images (MPR). A TD was defined as a thin-walled air sac at the paratracheal wall with a communication with the tracheal lumen. Congenital or acquired nature of TD was determined by the anatomical location, being usually the congenital ones located 4 to 5 cm below the vocal cords or a few centimeters above the carina in the right paratracheal area, whereas acquired ones were located at the level of the thoracic inlet, in the posterolateral tracheal wall. Presence of TD was assessed and their number and size recorded based on 2 axial diameters and size of neck.One or more TD were found in 96 patients (5.7% of sample), with a slight preponderance (65%) in male gender. Globally, 124 TD were detected; they were solitary in 75% of cases, double in 20.8%, and in about 4.2% they were triple. Average size of the TD was 1.3×4.9 mm with a mean width of the neck of 1.9 mm. The peak of prevalence (9%) was in patients belonging to the fourth-decade group (see ). According to their anatomical location, the majority (97.6%) of TD were acquired in nature and devoided of specific symptoms (see below).(Table is included in full-text article.)Acquired TD were detected in about 1 out of 20 of thoracic CTs and were usually incidentally. Our findings show a slightly higher frequency than previously reported. The most frequent presentation was in male and as a single entity. Clinically, TD was not associated with specific symptoms, in particular with chronic cough or Chronic Obstructive Pulmonary Disease (COPD).

Learning curve for endorectal ultrasound in young and elderly: lights and shades.

Aim of the study is to highlight difficulties faced by an inexperienced surgeon in approaching endorectal-ultrasound, trying to define when learning curve can be considered complete. A prospective analysis was conducted on endorectal-ultrasound performed for subperitoneal rectal adenocarcinoma staging in the period from January 2008 to July 2013, reported by a single surgeon of Department of Oncology, Section of General Surgery, "San Luigi Gonzaga" Teaching Hospital, Orbassano (Turin, Italy); the surgeon had no previous experience in endorectal-ultrasound. Fourty-six endorectal-ultrasounds were divided into two groups: early group (composed by 23 endorectal-ultrasounds, made from January 2008 to May 2009) and late group (composed by 23 endorectal-ultrasound, carried out from June 2009 to July 2013). In our experience, the importance of a learning curve is evident for T staging, but no statystical significance is reached for results deal with N stage. We can conclude that ultrasound evaluation of anorectal and perirectal tissues is technically challenging and requires a long learning curve. Our learning curve can not be closed down, at least for N parameter.

Use of a simplified consent form to facilitate patient understanding of informed consent for laparoscopic cholecystectomy.

BACKGROUND: Surgical informed consent forms can be complicated for patients to read and understand. We created a consent form with key information presented in bulleted texts and diagrams combined in a graphical format to facilitate the understanding of information during the verbal consent discussion. METHODS: This prospective, randomized study involved 70 adult patients awaiting cholecystectomy for gallstones. Consent was obtained after standard verbal explanation using either a graphically formatted (study group, n=33) or a standard text document (control group, n=37). Comprehension was evaluated with a 9-item multiple-choice questionnaire administered before surgery and factors affecting comprehension were analyzed. RESULTS: Comparison of questionnaire scores showed no effect of age, sex, time between consent and surgery, or document format on understanding of informed consent. Educational level was the only predictor of comprehension. CONCLUSIONS: Simplified surgical consent documents meet the goals of health literacy and informed consent. Educational level appears to be a strong predictor of understanding.
