ABSTRACT

OBJECTIVES: To assess whether ultrasound elastography (USE) with strain ratio increases diagnostic accuracy of Doppler ultrasound in further characterisation of cytologically Thy3 thyroid nodules. METHODS: In two different university diagnostic centres, 315 patients with indeterminate cytology (Thy3) in thyroid nodules aspirates were prospectively evaluated with Doppler ultrasound and strain ratio USE before surgery. Ultrasonographic features were analysed separately and together as ultrasound score, to assess sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). Receiver operating characteristic (ROC) curves to identify optimal cut-off value of the strain ratio were also provided. Diagnosis on a surgical specimen was considered the standard of reference. RESULTS: Higher strain ratio values were found in malignant nodules, with an optimum strain ratio cut-off of 2.09 at ROC analysis. USE with strain ratio showed 90.6% sensitivity, 93% specificity, 82.8% PPV, 96.4% NPV, while US score yielded a sensitivity of 52.9%, specificity of 84.3%, PPV 55.6% and NPV 82.9%. The diagnostic gain with strain ratio was statistically significant as proved by ROC areas, which was 0.9182 for strain ratio and 0.6864 for US score. CONCLUSIONS: USE with strain ratio should be considered a useful additional tool to colour-Doppler US, since it improves characterisation of thyroid nodules with indeterminate cytology. KEY POINTS: • Strain ratio measurements improve differentiation of thyroid nodules with indeterminate cytology • Elastography with strain ratio is more reliable than ultrasound features and ultrasound score • Strain ratio may help to better select patients with Thy 3 nodules candidate for surgery.

ABSTRACT

BACKGROUND: The safety and diagnostic accuracy of colonoscopy depend on the quality of colon cleansing. The adenoma detection rate is usually used as a quality measurement score. OBJECTIVE: We aimed to introduce and evaluate three new parameters to determine polyps and adenomas segmental localization and their distribution in association with different bowel preparation levels during colonoscopy. We introduce the multiple adenoma detection rate (the percentage of patients with >2 adenomas diagnosed during colonoscopy), the zonal adenoma detection rate (the percentage of patients with >2 adenomas diagnosed during colonoscopy in different colon areas (rectum, sigmoid, descending, transverse, ascending and cecum colon)), and multi-zone adenoma detection rate (the percentage of patients with >2 adenomas diagnosed during colonoscopy in different colon areas with at least a segment between them with or without lesions (i.e. rectum and descending colon with or without lesions in the sigmoid)). METHODS: We prospectively enrolled outpatients who underwent colonoscopy from January 2013 to October 2014. The bowel preparation quality, according to the Aronchick modified scale, number and location of lesions, Paris classification and histology, were recorded. The multiple adenoma/polyp detection rate, zonal adenoma/polyp detection rate, and multi-zone adenoma/polyp detection rate were determined. RESULTS: In total, 519 consecutive patients (266/253 M/F; mean age 55.3 ± 12.8 years) were enrolled. The adenoma and polyp detection rates were 21% and 35%, respectively. Multiple adenomas were detected in 28 patients. Adenoma and polyp detection rate and new parameters were statistically significantly higher in the optimal as compared with the adequate bowel preparation. CONCLUSIONS: An optimal level of bowel preparation was strongly associated not only with a higher adenoma detection rate, but also with a higher chance of detecting multiple clinically relevant lesions in adjacent or discrete segments of the colon.

ABSTRACT

BACKGROUND: The rising interest towards minimally invasive surgery has led to the introduction of laparo-endoscopic single site (LESS) surgery as the natural evolution of conventional multiport laparoscopy. However, this new surgical approach is hampered with peculiar technical difficulties. The SPIDER surgical system has been developed in the attempt to overcome some of these challenges. Our study aimed to compare standard laparoscopy and SPIDER technical performance on a surgical simulator, using standardized tasks from the Fundamentals of Laparoscopic Surgery (FLS). METHODS: Twenty participants were divided into two groups based on their surgical laparoscopic experience: 10 PGY1 residents were included in the inexperienced group and 10 laparoscopists in the experienced group. Participants performed the FLS pegboard transfers task and pattern cutting task on a laparoscopic box trainer. Objective task scores and subjective questionnaire rating scales were used to compare conventional laparoscopy and SPIDER surgical system. RESULTS: Both groups performed significantly better in the FLS scores on the standard laparoscopic simulator compared to the SPIDER. Inexperienced group: Task 1 scores (median 252.5 vs. 228.5; p = 0.007); Task 2 scores (median 270.5 vs. 219.0; p = 0.005). Experienced group: Task 1 scores (median 411.5 vs. 309.5; p = 0.005); Task 2 scores (median 418.0 vs. 331.5; p = 0.007). Same aspects were highlighted for the subjective evaluations, except for the inexperienced surgeons who found both devices equivalent in terms of ease of use only in the peg transfer task. CONCLUSIONS: Even though the SPIDER is an innovative and promising device, our study proved that it is more challenging than conventional laparoscopy in a population with different degrees of surgical experience. We presume that a possible way to overcome such challenges could be the development of tailored training programs through simulation methods. This may represent an effective way to deliver training, achieve mastery and skills and prepare surgeons for their future clinical experience.

ABSTRACT

INTRODUCTION: Lungs and liver are the most common sites of colorectal cancer metastases after regional lymph nodes, but metastases to unusual sites are reported. Heterotopic bone formation in soft tissues from colorectal cancer is a rare metastatic occurrence. CASE PRESENTATION: We present the case of a 29-year-old Caucasian man affected by colon adenocarcinoma with multiple soft tissue metastases visualized by magnetic resonance imaging, computed tomography scan and scintigraphic bone scan. We suppose that these findings can be due to the fact that the tracer is concentrated in the ossification nidus of soft metastases. CONCLUSIONS: Our experience suggests that, in the presence of colon adenocarcinoma, a bone scan could be a sensible tool to highlight bone lesions or heterotopic bone nidus in soft tissues and that any subcutaneous lesion should be resected to avoid underestimating a potential malignancy.

ABSTRACT

Cardiac echinococcus is a rare affliction of the heart caused by the tapeworm Echinococcus granulosus. Primary echinococcosis of the heart represents 0.5-2% of all hydatid disease cases in endemic regions. It evolves slowly, explaining its rarity in children. We report the case of a 11-year-old child affected by a giant cardiac cyst of the left ventricle (LV). The patient underwent cardiac surgery and medical treatment. A retrospective review of the current literature was realized. We found 18 cases: the mean age was 11-years old. Nine cysts were localized in the LV, four in the interventricular septum, three in the right ventricle, and two in the right atrium. All underwent surgery except six patients. Routine echocardiographic screening may be useful in endemic regions where infestation is common. Cardiac echinococcus should be diagnosed in the early and uncomplicated stages and be removed surgically even in asymptomatic patients.

ABSTRACT

Purpose. Bowel preparation for surveillance endoscopy following surgery can be impaired by suboptimal bowel function. Our study compares two groups of patients in order to evaluate the influence of colorectal resection on bowel preparation. Methods. From April 2010 to December 2011, 351 patients were enrolled in our retrospective study and divided into two homogeneous arms: resection group (RG) and control group. Surgical methods were classified as left hemicolectomy, right hemicolectomy, anterior rectal resection, and double colonic resection. Bowel cleansing was evaluated by nine skilled endoscopists using the Aronchick scale. Results. Among the 161 patients of the RG, surgery was as follows: 60 left hemicolectomies (37%), 62 right hemicolectomies (38%), and 33 anterior rectal resections (20%). Unsatisfactory bowel preparation was significantly higher in resected population (44% versus 12%; P value = 0.000). No significant difference (38% versus 31%, P value = ns) was detected in the intermediate score, which represents a fair quality of bowel preparation. Conclusions. Our study highlights how patients with previous colonic resection are at high risk for a worse bowel preparation. Currently, the intestinal cleansing carried out by 4 L PEG based preparation does not seem to be sufficient to achieve the quality parameters required for the post-resection endoscopic monitoring.

ABSTRACT

BACKGROUND: Construct validity of virtual laparoscopic simulators for basic laparoscopic skills has been proposed; however, it is not yet clear whether the simulators can identify the actual experience of surgeons in more complex procedures such as laparoscopic Roux-en-Y gastric bypass. This study tested the ability of the Lap Mentor simulator to recognize the experience in advanced laparoscopic procedures and to assess its role in the certification of bariatric surgeons. METHODS: Twenty surgeons were divided into two groups according to their experience in laparoscopic and bariatric surgery. The general group included 10 general surgeons performing between 75 and 100 nonbariatric laparoscopic procedures. The bariatric group included 10 bariatric surgeons performing between 50 and 100 laparoscopic bariatric procedures. Participants were tested on the simulator in one basic task (task 1: eye-hand coordination) and in two tasks of the gastric bypass module (task 2: creation of the gastric pouch; task 3: gastrojejunal anastomosis). RESULTS: Comparing the groups, no significant differences were found in task 1. Analyzing the results from the gastric bypass module (bariatric vs. general), in task 2, significant differences (p < 0.05) were found in the median volume of the gastric pouch (21 vs. 48 cm(3)), in the percentage of fundus included in the pouch (8.4 vs. 29.4 %), in the complete dissection at the angle of His (10 vs. 3), and in safety parameters. In task 3, significant differences were found in the size and position of enterotomies. CONCLUSIONS: The Lap Mentor may be proposed as a certification tool for bariatric surgeons because it also recognizes their specific skills in the technical details of the procedure that affect long-term results. Furthermore, the possibility of analyzing the performance in detail can help define areas where the surgeon is lacking. These findings indicate a potential role of the Lap Mentor in tailoring the training to maximize improvement.

ABSTRACT

PURPOSE: This study was done to compare quantitative elastosonography and ultrasound analysis in the characterisation of thyroid nodules. MATERIALS AND METHODS: From July 2009 to September 2011, 123 patients with 147 thyroid nodules were included in our study. All patients enrolled had to undergo thyroidectomy because of nodular thyroid disease (goitre or nodules). After preliminary examination with conventional ultrasound (US) and colour Doppler US, the patients were examined with elastosonography, using high-level equipment (Toshiba Aplio XG) and quantitative software (Elasto-Q). Each lesion was characterised using an US score (echogenicity, borders, microcalcifications and colour Doppler pattern), and then by elastosonographic strain ratio. Each patient subsequently underwent thyroidectomy. Histological results were used as the gold standard. RESULTS: Histological examination demonstrated 89 benign and 58 malignant lesions. On average, the strain ratio value was 2.84±2.69 (range, 0.05-14.5; p=0.001). Sensitivity and specificity of the US score were about 56% and 72%, respectively, whereas those of the strain ratio were 93% and 89%, using a cut-off of 2 obtained with receiver operating characteristic (ROC) curve analysis. Elastosonography was more accurate than US and colour Doppler US in characterising thyroid nodules (p=0.002). CONCLUSIONS: Quantitative elastosonography is a useful diagnostic tool in the evaluation of thyroid lesions, and can be used to limit fine-needle aspiration cytology and improve the selection of patients for thyroidectomy.

ABSTRACT

BACKGROUND: Video-games have become an integral part of the new multimedia culture. Several studies assessed video-gaming enhancement of spatial attention and eye-hand coordination. Considering the technical difficulty of laparoscopic procedures, legal issues and time limitations, the validation of appropriate training even outside of the operating rooms is ongoing. We investigated the influence of a four-week structured Nintendo® Wii™ training on laparoscopic skills by analyzing performance metrics with a validated simulator (Lap Mentor™, Simbionix™). METHODOLOGY/PRINCIPAL FINDINGS: We performed a prospective randomized study on 42 post-graduate I-II year residents in General, Vascular and Endoscopic Surgery. All participants were tested on a validated laparoscopic simulator and then randomized to group 1 (Controls, no training with the Nintendo® Wii™), and group 2 (training with the Nintendo® Wii™) with 21 subjects in each group, according to a computer-generated list. After four weeks, all residents underwent a testing session on the laparoscopic simulator of the same tasks as in the first session. All 42 subjects in both groups improved significantly from session 1 to session 2. Compared to controls, the Wii group showed a significant improvement in performance (p<0.05) for 13 of the 16 considered performance metrics. CONCLUSIONS/SIGNIFICANCE: The Nintendo® Wii™ might be helpful, inexpensive and entertaining part of the training of young laparoscopists, in addition to a standard surgical education based on simulators and the operating room.

ABSTRACT

BACKGROUND: Deep Vein Thrombosis (DVT) is an important cause of morbidity and is the first cause of maternal death after delivery in Western Nations. The risk of venous thromboembolism is present throughout the pregnancy and is maximal during postpartum, especially after twin delivery. Many of the signs and symptoms of DVT overlap those of a normal pregnancy causing difficulty for diagnosis. CASE REPORT: We report the case of a 33 year-old woman transferred to our Department one week after caesarean section for twin delivery. She presented with severe abdominal pain, fever, abdominal distension and shortness of breath. She had no personal or family history of thromboembolism. Computerized Tomography Scan revealed right ovarian vein thrombosis, left renal vein thrombosis extending up to the Inferior Vena Cava and pulmonary embolism with bilateral pleural effusion. Caval filter was positioned and anticoagulation therapy associated with antibiotics was instituted. Pancreatitis showed up two days after and was promptly treated. Three months after discharge the caval filter was removed and oral anticoagulation was stopped. During a 12-months follow-up, she remained stable and symptom free. RESULTS: Ovarian vein thrombosis is rare but recognition of signs and symptoms is fundamental to start adequate therapy and avoid potential serious sequelae. The risk for maternal postpartum ovarian vein thrombosis is increased by caesarean section delivery of twins. Such patients should be closely monitored. We illustrated how an underestimated condition can lead to massive complications.

ABSTRACT

PURPOSE: Detection of cancer in patients with AAA complicates the treatment of both diseases. AAA associated with RN are rare, with an incidence of 0.1-3% representing a challenge in defining the surgical timing and approach. We discuss the rational for the treatment in patients with concomitant patologies. CASE REPORT: A 65 years-old man was diagnosed with both AAA and Renal Cell Carcinoma. The patient underwent first EVAR followed by renal embolization and Radical Nefrectomy. Three months later a Type II Endoleak was diagnosed and treated successfully. At 1 year follow-up the patient is disease free with complete exclusion of aneurysm sac. CONCLUSION: AAA can be successfully repaired in patients with renal neoplasm with great results, either simultaneously or in two stages. EVAR is a good alternative for such complex patients.

ABSTRACT

PURPOSE: To assess the clinical value of quantitative elastosonography compared with multiparametric ultrasound in differentiating the nature of thyroid nodules. METHODS AND MATERIALS: Ninety-seven consecutive patients (32 males, 65 females, mean age, 54 years, range 20-81 years) with thyroid nodules previously detected at color-Doppler ultrasound (CDUS), were prospectively examined with elastosonography with dedicated quantitative software (Elasto-Q, Toshiba) before surgery. Ultrasound examination and elastosonography were evaluated by two investigators in consensus. US features, color-Doppler pattern, and strain ratio value were evaluated. Sensitivity and specificity of CDUS and sono-elastography were compared using X(2) test and ROC curves. RESULTS: Sensitivity and specificity of hypoechogenicity, irregular margins or suspicious halo features, CDUS blood flow pattern, and strain ratio in the diagnosis of malignant nodules were 56.8%, 62.2%, 54.1% and 97.3% and 71.7%, 93.3%, 28.3%, and 91.7%, respectively. Elastosonography was more sensitive and specific than all ultrasonographic features in predicting malignancy of the thyroid nodules (p<0.0001). According to elastosonographic features the lesions characterized by strain ratio ≥ 2 were highly likely to be of malignant nature (p<0.0001, O.R. 396, 95%, CI: 44-3530). CONCLUSIONS: The results of the present study suggest that elastosonography with Q system is a valuable tool in the characterization of thyroid nodules and it seems to be far more accurate than CDUS. These findings as well as those of previous studies support its use in selecting patients who are candidates for surgery.

ABSTRACT

AIM: To investigate the effectiveness of low-volume plus ascorbic acid [polyethylene glycol plus ascorbic acid (PEG + Asc)] and high-volume plus simethicone [polyethylene glycol plus simethicone (PEG + Sim)] bowel preparations. METHODS: A total of one hundred and forty-four outpatients (76 males), aged from 20 to 84 years (median age 59.5 years), who attended our Department, were divided into two groups, age and sex matched, and underwent colonoscopy. Two questionnaires, one for patients reporting acceptability and the other for endoscopists evaluating bowel cleansing effectiveness according to validated scales, were completed. Indications, timing of examination and endoscopical findings were recorded. Biopsy forceps were used as a measuring tool in order to determine polyp endoscopic size estimation. Difficulty in completing the preparation was rated in a 5-point Likert scale (1 = easy to 5 = unable). Adverse experiences (fullness, cramps, nausea, vomiting, abdominal pain, headache and insomnia), number of evacuations and types of activities performed during preparation (walking or resting in bed) were also investigated. RESULTS: Seventy-two patients were selected for each group. The two groups were age and sex matched as well as being comparable in terms of medical history and drug therapies taken. Fourteen patients dropped out from the trial because they did not complete the preparation procedure. Ratings of global bowel cleansing examinations were considered to be adequate in 91% of PEG + Asc and 88% of PEG + Sim patients. Residual Stool Score indicated similar levels of amount and consistency of residual stool; there was a significant difference in the percentage of bowel wall visualization in favour of PEG + Sim patients. In the PEG + Sim group, 12 adenomas ≤ 10 mm diameter (5/left colon + 7/right colon) vs 9 (8/left colon + 1/right colon) in the PEG + Asc group were diagnosed. Visualization of small lesions seems to be one of the primary advantages of the PEG + Sim preparation. CONCLUSION: PEG + Asc is a good alternative solution as a bowel preparation but more improvements are necessary in order to achieve the target of a perfect preparation.

ABSTRACT

PURPOSE: In view of divergent outcomes of surgery for rectal cancer despite standard protocols, the aim of this study was to provide a basis for improving lymph node assessment by defining the number, shape, and distribution of all lymphatic structures in the mesorectum. METHODS: Cadavers from 6 males and 6 females who died from causes other than colorectal or neoplastic pathologies were studied. Rectum and mesorectum were excised en bloc. The adipose tissue was separated from the rectum and divided into 9 sections before fixing the specimen in paraffin, cutting into smaller portions, and staining with hematoxylin and eosin. Slides were analyzed with an optical microscope, and identified lymph nodes were counted in each section. RESULTS: The mean age of the deceased was 52.7 (range, 26-65) years. No evidence of previous history of neoplastic pathology or any type of premortal colorectal inflammatory process was found. A total of 412 lymph nodes were identified, with a mean of 34.3 (SD, 2.1; range, 31-37) lymph nodes per cadaver. The mean number of lymph nodes differed significantly across levels of the mesorectum, with 22.2 lymph nodes in the upper, 9.8 in the middle, and 2.3 in the lower sections; 266 (64.6%) of all lymph nodes were located in the upper third of the mesorectum. Distribution density was higher in the proximal posterior sections, with 197 lymph nodes (47.8%) in the upper 2 thirds of the posterior mesorectum. Node diameter was less than 5 mm in 330 (80%) of 412 nodes. CONCLUSIONS: Our study confirmed that more than 30 lymph node units normally exist in the mesorectal area. In view of previous studies demonstrating advantages of increasing the number of lymph nodes evaluated, staging of rectal cancer might be improved by counting more than 12 lymph nodes per specimen.

ABSTRACT

Retroperitoneal lymph node dissection (RPLND) is the most accurate method to evaluate the presence and extent of retroperitoneal nodal metastases in clinical stage I non-seminomatous germ cell testicular carcinoma. In our Department the open "nerve sparing" RPLND is already the standard surgical treatment for these tumors and laparoscopic technique is employed in surgical treatment of digestive diseases as cholelithiasis, hiatal hernias and gastrointestinal tumors; we report our first experience with laparoscopic RPLND in patients with low stage non-seminomatous germ cell testicular tumors (NSGCTT). A laparoscopic modified template RPLND was performed in 5 high-risk patients with non-seminomatous germ cell clinical stage I tumors by a transperitoneal approach. In 4 of the 5 cases a template dissection was performed. In one pathological stage II tumor a limited lymph node dissection was performed and the patient underwent postoperative chemotherapy. Mean operative time was 190 minutes (range 160-210). No retrograde ejaculation occurred. The mean number of dissected nodes was 21 (range 16-25). At mean follow-up of 16.3 months (range 12-21) the 4 operated patients with pathological stage I NSGCTT are disease free without ejaculatory or urinary dysfunction. Our preliminary experience suggests that laparoscopic RPLND for stage I NSGCTT is feasible and safe for surgeons largely trained in either laparoscopic digestive surgery or open RPLND for whom the learning curve of that minimally invasive approach is lower than expected.

ABSTRACT

BACKGROUND/AIMS: The authors report their experience in choosing the surgical treatment for early gastric cancer. METHODOLOGY: A retrospective study was conducted to examine the long-term outcome of 18 patients with early gastric cancer (10%) on a series of 180 patients treated for gastric carcinoma by the same surgical équipe from January 1986 to June 1997. Radical surgery with gastrectomy and extended lymphadenectomy ("regional" from 1986 to 1991; D2 from 1992 to 1997) was chosen as standard treatment for early gastric cancer except in elderly or high-risk patients and in cases of mucosal tumors diagnosed at definitive histology after surgery for benign diseases in which limited surgery was performed. RESULTS: All patients received curative (R0) surgery. One patient with mucosal-N1 tumor and another one with submucosal-N0 tumor died because of gastric cancer at 51 and 42 postoperative months respectively. The mean follow-up time was 99.8 (11-193) months. The overall 5-year and 10-year survival rates are 86.7% and 86.7% respectively. The 5- and 10-year survival rates for intramucosal tumors are 91% and 91% respectively and for submucosal cancer are 75% and 75% (P=0.39). CONCLUSIONS: According to the prognostic value of nodal involvement and the difficulty in achieving a preoperative accurate diagnosis of depth of invasion and of nodal involvement in early gastric cancer, a radical gastric resection with D2-lymphadenectomy should be performed.
