Background: Wire-guided localization is the gold-standard for the detection of non-palpable breast lesions, although with acknowledged limitations. The aim of this study was to evaluate the combined use of LOCalizerr™ (Hologic, Santa Carla, CA, USA), and intraoperative ultrasound (IOUS) for localization and surgery of non-palpable breast cancer. Patients and Methods: Patients with non-palpable breast lesions underwent localization procedure with LOCalizer™ and IOUS. After the placement of the marker, eight measures were made to guide the excision. LOCalizerr™ Pencil and IOUS were performed to obtain the distance between the dissection plane and the margins of lesions. Results: The procedure was feasible in the five enrolled patients and associated with clear oncological margins in all cases. Moreover, a high satisfaction according to Likert scale for surgeons, radiologists and patients, performing limited and tailored resections, was reported. Conclusion: Combining LOCalizerr™ and IOUS is an effective method for locating non-palpable breast cancer, guarantying excellent oncological and cosmetic results.

Introduction Hemostasis during thyroidectomy is essential; however the most efficient and cost-effective way to achieve this is unclear. The aim of this study was to evaluate the outcome of total thyroidectomy (TT) performed with the combination of harmonic scalpel (HS) and an advanced hemostatic pad (Hemopatch). Methods Patient undergone TT were divided into two groups: HS + hemopatch and HS + traditional hemostasis groups. The primary endpoint was 24-h drain output and blood-loss requiring reintervention. Secondary endpoints included surgery duration, postsurgical complications and hypocalcemia rates. Results Between September 2014 and March 2015, 60 patients were enrolled (30 to Hs + Hemopatch, 30 to Hs and standard hemostasis); 71.4% female; mean age 48.5 years. The 24-h drain output was lower in the HS + hemopatch group compared with standard TT. HS and hemopatch also had a shorter mean surgery time (p Conclusion combination of hemopatch plus HS is effective and safe for TT with a complementary hemostatic approach.

OBJECTIVE. The purpose of this study was to assess the long-term efficacy of percutaneous ethanol injection (PEI) for the treatment of hyperfunctioning thyroid nodules. MATERIALS AND METHODS. One hundred twenty-five patients (88 women, 37 men; age range, 17–76 years; mean age, 53 years) with 127 hyperfunctioning thyroid nodules (volume, 1.2–90 mL; mean, 10.3 mL) were treated with PEI. There were 1–11 PEI sessions per patient (average, 3.9) performed, with injection of 1–14 mL of ethanol per session (total injected ethanol per patient, 3–108 mL; mean, 14.0 mL). Efficacy of the treatment was assessed with color Doppler sonography; scintigraphy; and free triiodothyronine (FT3), free thyroxine (FT4), and thyroid-stimulating hormone (TSH) assays. Follow-up (9–144 months; median, 60 months) was performed with TSH and color Doppler sonography every 2 months for 6 months and every 6 months thereafter. RESULTS. Three (2.4%) of 125 patients refused completion of PEI therapy because of pain. Results are reported in 122 patients with 124 nodules. All 122 patients showed posttreatment normal levels of FT3, FT4, and TSH. A complete cure (absent uptake in the nodule and recovery of normal uptake in the thyroid parenchyma) was obtained in 113 (93%) of 122 patients—115 (92.7%) of 124 treated nodules. Residual hyperfunctioning nodular tissue along with decreased thyroid parenchyma uptake (partial cure) was present in nine patients accounting for nine (7.3%) of 124 nodules. Rates of complete cure after PEI were: overall nodules, 115 (92.7%) of 124; nodules ≤ 10 mL, 63 (94.0%) of 67; nodules > 10 to ≤ 30 mL, 32 (91.4%) of 35; nodules > 30 to ≤ 60 mL, 17 (89.5%) of 19; nodules > 60 mL, three (100%) of three. The overall rate of major complications (transient laryngeal nerve damage, two patients; abscess and hematoma, one patient each) was four (3.2%) of 125 patients. Follow-up examinations showed marked shrinkage of 112 treated nodules ranging from 50% to 90% of the pretreatment volume (mean, 66%) and new growth of hyperfunctioning tissue in four patients at color Doppler sonography and scintigraphy at 12, 18, 18, and 48 months’ follow-up, respectively. However, all patients remained euthyroid (low or normal TSH and normal FT3 and FT4) during follow-up. CONCLUSION. PEI of hyperfunctioning thyroid nodules seems to be an effective and safe alternative to traditional treatment. It also appears to be effective in patients with hyperfunctioning thyroid nodules larger than 30 mL.

INTRODUCTION: Hemostasis during thyroidectomy is essential; however, the safest, most efficient and cost-effective way to achieve this is unclear. The aim of this study was to evaluate the outcome of total thyroidectomy (TT) performed with combination of harmonic scalpel (HS) and Floseal. METHODS: Patients undergone TT were divided into two groups: HS + Floseal and traditional hemostasis groups. The primary endpoint was 24-h drain output and blood-loss requiring reintervention. Secondary endpoints included surgery duration, postsurgical complications and hypocalcemia rates. RESULTS: Between September 2012 and January 2014, 165 patients were enrolled (100 to HS + Floseal, 65 to standard hemostasis); 80.5% female; mean age 42.3 years. The 24-h drain output was lower in the HS + Floseal group compared with standard TT. HS + Floseal also had a shorter mean surgery time (p < 0.0001) vs standard TT. No differences in post-surgical complications and in hypocalcemiarates between groups. CONCLUSION: combination of Floseal plus the HS is effective and safe for TT and it provides a complementary hemostatic approach.

Introduction Mastectomy for breast cancer may bring the patient to develop long term issues concerning the psychological and physical status. Immediate breast reconstruction (IBR) should be considered and proposed by physicians as an integrated procedure in the surgical approach to breast cancer to reduce further surgery. Acellular dermal matrix (ADM) has been used in revision breast reconstruction for fold malposition, capsular contracture and rippling also, showing good outcomes with low risk of complications. Aim of this study was to verify if the known advantages in using ADM for IBR would led to lower rates of seroma formation, infection, skin flap necrosis and overall complication related to the implant. Methods We performed a prospective study, including all consecutive patients undergone to IBR with biological graft with ADM between January 2012 and January 2013 at our Institution. Data on major issues of the patients and complications were recorded. All patients underwent to IBR with ADM (Tutomesh) implant with or without fibrin sealant positioning. Results A total of 24 patients underwent 28 immediate breast reconstruction with Tutomesh ADM implant. Main postoperative complications included seroma formation in 20.8% (5 pts), infection in 8.3% (2 pts) and hematoma in 4.2% (1 pt). There were any skin flap necrosis in the study. Diabetes was associated in two cases with edema and ecchymosis; hypertension with infection in one case (implant removal) and seroma in one case. First class of obesity (BMI 30–32.7) was associated with seroma in 3 cases, and with infection in one. In patient without fibrin sealant (12 patients – 13 breasts) complications were represented by hematoma (1 pt. 4.2%), infection (1 pt. 4.2%; implant removal) and seroma (4 pts 16.8%). Conclusions The use of Tutomesh ® bovine pericardium for immediate breast is safe and technically useful. Complications rate is not high, except for seroma formation that can be reduced by the contemporary use of fibrin sealant.

Background We conducted an observational multicentric clinical study on a cohort of patients undergoing thyroidectomy for thyroid carcinoma. The aim of this study was to evaluate the benefits of the use of ultrasonic dissector (UAS) vs. the use of a conventional technique (vessel clamp and tie) in patients undergoing thyroid surgery for cancer. Methods From June 2009 to May 2010 we evaluated 321 consecutive patients electively admitted to undergo total thyroidectomy for thyroid carcinoma. The first 201 patients (89 males, 112 females) presenting to our Department underwent thyroidectomy with the use of UAS while the following 120 patients (54 males, 66 females) underwent thyroidectomy performed with a conventional technique (CT): vessel clamp and tie. Results The operative time (mean: 75 min in UAS vs. 113 min in CT, range: 54 to 120 min in UAS vs. 68 to 173 min in CT) was much shorter in the group of thyroidectomies performed with UAS. The incidence of transient laryngeal nerve palsy (UAS 3/201 patients (1.49%); CT 1/120 patients (0.83%)) was higher in the group of UAS; the incidence of permanent laryngeal nerve palsy was similar in the two groups (UAS 2/201 patients (0.99%) vs. CT 2/120 patients (1.66%)). The incidence of transient hypocalcaemia (UAS 17/201 patients (8.4%) vs. CT 9/120 patients (7.5%)) was higher in the UAS group; no relevant differences were reported in the incidence of permanent hypocalcaemia in the two groups (UAS 5/201 patients (2.48%) vs. 2/120 patients (1.66%)). Also the average postoperative length of stay was similar in two groups (2 days). Conclusion The only significant advantage proved by this study is represented by the cost-effectiveness (reduction of the usage of operating room) for patients treated with UAS, secondary to the significant reduction of the operative time. The analysis failed to show any advantages in terms of postoperative transient complications in the group of patients treated with ultrasonic dissector: transient laryngeal nerve palsy (1.49% in UAS vs. 0.83% in CT) and transient hypocalcaemia (8.4% in UAS vs. 7.5%in CT). No significant differences in the incidence of permanent laryngeal nerve palsy (0.8% in UAS vs. 1.04% in CT) and permanent hypocalcaemia (2.6% in UAS vs. 2.04% in CT) were demonstrated. The level of surgeons’ expertise is a central factor, which can influence the complications rate; the use of UAS can only help surgical action but cannot replace the experience of the operator.

In the present study the authors assess the advantages of new technologies in thyroid surgery: to prevent nerve injury by using an intra-operative continuous nerve-monitoring techniques and to compare the real advantages of advanced coagulation devices.Among a series of 440 thyroidectomies (jan 2004-feb 2006) the Authors reviewed charts from two groups: (1) 240 total thyroidectomies performed using the traditional monopolar electrocautery, non-absorbable stitches for the principal vascular pedicles. (2) 140 total thyroidectomies performed using dedicated small bipolar electro thermal coagulator (ligasure-precise). (3) Since 2006 in a double blind group selection of 70, we've performed sutureless thyroidectomy with continuous intraoperative nerve monitoring using dedicated endotracheal tube. Mean operative time, post-operative bleeding, post-operative stay, incidence of transient or definitive laryngeal nerve lesions, incidence of permanent or transient hypocalcaemia, costs of the procedures were analyzed.Major complications in the first two groups compared with the data of the literature are absolutely over-imposable, except a reduction of incidence of transient hypocalcaemia in the Precise group, but if we compare data of the 3rd group (NIM), we find a significative reduction of transient and permanent laryngeal nerve palsy incidence.This new technology offers several advantages: (1) atraumatic; (2) easy to use; (3) continuous monitoring and audio feedback to the surgeon (4) works outside the operation field (5) high sensitiveness. Cost-analysis confirm that NIM + ligasure have same or less cost and time and probably less complications than traditional Total Thyroidectomy.

Intra abdominal hypertension (IAH) is defined as an intra-abdominal pressure (IAP)12 mmHg. Abdominal compartment syndrome (ACS) is defined as an IAP above 20 mmHg with evidence of organ dysfunction/failure. The real incidence of the ACS is not clear, because there are few perspective studies. The origin of ACS can be divided into retroperitoneal, intraperitoneal, parietal and intestinal, and the diagnostic algorithm includes base and toxicological laboratory examinations, thorax X-ray, abdomen X-ray, abdomen TC, peritoneal washing, abdomen ultrasonography, diagnostic laparoscopy, and measurement of IAP. To allow a suitable decompression and avoid the damages to the abdominal organs, abdominal wall normally is not sutured primarily but secondarily and there are many methods of temporary closing: absorbable net, non-absorbable nets, 'Bogota bag', 'vacuum pack ice', gradual approximation of side cutaneous edges on the half-way line with permanence of an ample ventral hernia that could be subsequently repaired, and the use of 'skin expanders'. Since January 2000, until December 2008, eight patients were submitted to laparostomy, four of them for re-laparotomy, with mortality incidence of 37.5%. The defective size to fill was on the average 300 cm as reported by Bradley and Bradley (J Clin Invest 26:1010-1015, 1947). The abdominal wall reconstruction was performed using ample muscle edges derived from the slip in medial sense of the rectus muscle of the abdomen 'unmoored' through an incision 1 cm distant from semi-lunar line, and using absorbable prosthesis to cover the solution of continuity, thus allowing the closing of defects over 30 cm. We have found median post surgical hernia in one patient corrected in accordance with the time using polypropylene prosthesis. In one patient with parietal disaster and multiple traumatic splanchnic ruptures, we have used a pure pork-derived acellular collagen mesh (Permacol(®)) to close the wound, leaving enough space between fascia extremities, to solve the IAP. The employment of ample muscle edges represents the ideal solution in the reconstruction of the abdominal walls after laparotomic operations, offering a valid dynamic support preferable in comparison with the employment of alloplastic material. In consideration of the limits of this technique in the enormous parietal disaster-ACS treatment, we describe a new kind of innovative mesh application (Permacol(®)), most often used for parietal disaster or enormous incisional hernias, which can easily be preferred to dual mesh prosthesis, having a better biological profile and no capacity to produce intestinal adherences.

Based on the theory--which is now acknowledged-of a clinical difference between proximal and distal colon cancer and on the results of recent genetic and microbiological studies, a minority of authors have assumed that also in the sphere of right-sided colon cancer, tumors at three different locations, namely, the cecum and ascending and transverse colon, can be considered to be biologically different. These studies have provided the basis for a retrospective study carried out on 50 patients admitted to our department from 1996 to 2008 for tumor pathology of the right colon. The tumor was considered to be a unified biological entity and assessed in relation to the three above-mentioned locations. The results verify that the aggressive of the tumor increases from the cecum to the transverse, with a higher percentage of cecal tumors being in I stage, more tumors in the ascending colon being in II stage, and more transverse tumors, with the largest percentage of N+ and M+, in stages III and IV. This difference in biological behavior for the three tumor locations has been also found in terms of sensitiveness, both pre- and post-operation, of tumor markers CEA, TPA, and CA19-9. Clinical data revealed a binary relationship between the transverse, cecum, and ascending tumors, which ultimately affects patient mortality, which increases in a directly proportional way from the cecum to the transverse-in the case of a tumor at one of these locations.

AIM: The ductal carcinoma in situ (DCIS) is a more and more frequent neoplasia, representing over 25% of diagnosed breast cancer in recent surveys.It is particularly interesting as concerns several aspects of which the most important are issues linked to clinical diagnosis and the difficulties of histopathological classification, with evident and important therapeutic implications. PATIENTS AND METHODS: The authors report their experience about 161 ductal carcinoma in situ of the breast. Guidelines for surgical treatment are: radiological or clinical diagnosis, tumor's extension, histological classification, grading and margin status. At the present the authors prefer breast conserving surgery with tumor margin's study. They report their experience in the last seven years about sentinel lymph node biopsy. RESULTS: The most frequent histotype resulted comedocarcinoma (61,8%) followed by non comedo (38,2%). Local recurrence after DCIS therapy is 6,1%. CONCLUSIONS: 80-90% of the patients currently treated for DCIS present non-palpable breast lesions at diagnosis. Breast conserving surgery is the first choice and radiotherapy and endocrine therapy are indicated for selected patients.

BACKGROUND: Axillary lymphadenectomy remains an integral part of breast cancer treatment, yet seroma formation occurs in 15-85% of cases. Among methods to reduce seroma magnitude and duration, fibrin glue has been proposed in several studies with controversial results. PATIENTS AND METHODS: Ninety patients underwent quadrantectomy or mastectomy with level I/II axillary lymphadenectomy; a suction drain was fitted in all patients. Fibrin glue spray were applied to the axillary fossa in 45 patients; the other 45 patients were treated conventionally. RESULTS: Suction drainage was removed between post-operative (p.o.) days 3 and 4. Seroma magnitude and duration were significantly reduced (p 0.004 and 0.02, respectively), and there were fewer evacuative punctures, in patients receiving fibrin glue compared with the conventional treatment group. CONCLUSIONS: Use of fibrin glue does not always prevent seroma formation, but does reduce seroma magnitude, duration and evacuative punctures.

A retrospective study was carried out to assessed reliability of the prognostic factors (histology, age, sex, and stage), and standard procedures for the surgical treatment of differentiated thyroid cancers (DTC). From the 144 DTC cases reviewed with follow-up ranging from 1 to 25 years (m=6.33 years), total mortality for cancer was found to be 55% (8 patients), with a predictive positive value for recurrence of 95.4% and 91.8% at 12 and 24 months, respectively. Median survival was 8.8 years (range 1 to 25 years). The multivariate analysis showed that factors such as age > 45 years, histology of intermediate malignancy, size up to 1.5 cm, and presence of metastases, significantly worsened the prognosis, regardless of the intervention that was carried out. We suggest total thyroidectomy for the treatment of benign pathologies and confirmed or suspected cases of cancer. We reserve loboisthmectomy for the treatment of benign pathologies confined to one lobe or those with FNAB suggesting a follicular neoplasm.

BACKGROUND: We describe the clinical and color Doppler ultrasound findings in a series of cases of seeding from hepatocellular carcinoma (HCC) observed in patients treated with percutaneous ablation therapy (PAT) over a 15-year period. METHODS: We reviewed the clinical and imaging records of 12 patients with cirrhosis (nine men and three women, age range 51-82 years, mean age 63 years) that showed neoplastic seeding from HCC occurring after one or more PAT procedures. Five of 12 cases of seeding were observed as a complication of 1080 PAT procedures (0.46%) performed in 545 patients (0.96%) by two of the authors (L.T., G.F.) over a long period (15 years) at different institutions. The other seven patients had been treated with PAT procedures at other institutions and had come to our attention during post-treatment follow-up. RESULTS: The 12 patients who had seeding nodules had undergone the following PAT procedures: multisession conventional percutaneous ethanol injection (PEI) without anesthesia (four patients), single-session PEI with general anesthesia (three patients), single-session PEI with general anesthesia plus multisession conventional PEI (four patients), and single-session PEI plus radiofrequency ablation (one patient). Seeding nodules ranged from 0.9 to 6.0 cm (mean 1.7 cm). Eleven of 12 seeding nodules appeared as hypervascular hypoechoic nodules with smooth and regular margins and multiple intralesional vascular signals. CONCLUSIONS: Clinical and imaging findings of seeding from HCC should be recognized by physicians who perform follow-up ultrasound examinations of patients who are treated with PAT. Early diagnosis of seeding can be reliably made by scanning the abdominal wall with small probes in the area where the previous PAT has been performed. Hypoechoic hypervascular pattern of the seeding nodule allows definitive diagnosis.

Background Hypocalcemia caused by transient or definitive hypoparathyroidism is the most frequent complication after total thyroidectomy (TT). We aimed to compare the impact of age and the clinical usefulness of oral calcium and vitamin D supplements on postoperative hypocalcemia after TT, and to determine which risk factors are important for hypocalcemia incidence. Methods Two hundred consecutive patients treated by TT were included prospectively in the present study. All patients supplemented oral calcium and vitamin D in the post-operative time. The data concerning symptomatic and laboratoristichypocalcemia were collected. Patients were evaluated according to age, sex, postoperative serum calcium levels, and preoperative serum alkaline phosphatasis levels. Results Symptomatic hypocalcemia developed only in 19 patients (9.5%), whereas laboratory hypocalcemia developed in 36 patients (18%). The risk for postoperative hypocalcemia was increate 20-fold for patients older than 50 years. Conclusions Age is significantly associated with postoperative hypocalcemia. Implementing oral calcium and vitamin D after total thyroidectomy can reduce the incidence of hypocalcemia related to surgery.

Background Axillary lymphadenectomy or sentinel biopsy is integral part of breast cancer treatment, yet seroma formation occurs in 15-85% of cases. Among methods employed to reduce seroma magnitude and duration, fibrin glue has been proposed in numerous studies with controversial results. Methods Thirty patients over 60 years underwent quadrantectomy or mastectomy with level I/II axillary lymphadenectomy; a suction drain was fitted in all patients. Fibrin glue spray were applied to the axillary fossa in 15 patients; the other 15 patients were treated with harmonic scalpel. Results Suction drainage was removed between post-operative Days 3 and 4. Seroma magnitude and duration were not significant in patients receiving fibrin glue compared with the harmonic scalpel group. Conclusions Use of fibrin glue does not always prevent seroma formation, but can reduce seroma magnitude, duration and necessary evacuative punctures.

Malignant melanoma appears in typical sites where melanocytes can usually be found (skin, eyes, meninges, and anal region ).1 In the gastrointestinal (GI) tract, melanoma can be also found in the rectum and sigmoid colon by the local migration of primordial skin melanocytes.2 Some other rare sites of primary melanomas in the GI tract were described as the gall-bladder, stomach, small and large intestine, mouth, tongue, and esophagus.2–8 Generally, most GI melanomas are metastases from a skin tumor.9,10 We report the case of a patient with a first presentation of small-bowel melanoma, which was considered a primary site because of the absence of concurrent lesions and no history of removal of a melanoma or atypical melanocytic lesion from the skin or other organs.11

In the early days of video-assisted laparoscopic cholecystectomy (VLC), obesity was considered a contraindication for the procedure. We reviewed charts from 304 patients undergoing VLC; 90 patients were obese, and among these, according to a classification currently used by medical nutritionists and based on BMI, 45 were overweight (BMI > or = 25 < or = 29.9), 27 were considered conventionally obese (BMI > or = 30 and < 40) and 18 morbidly obese (BMI > or = 40). In this study we considered only the morbidly obese patients (5 males and 13 females). The average age was 42.3 years (range: 21-65) and the average weight 275 Ib (range: 186-331 Ib). Six patients had previously undergone abdominal surgery. All patients were symptomatic for gallstones, and 5 of them were suffering from acute cholecystitis. Mean operative time was 20 minutes (range: 10-45 minutes) longer than that of non-obese patients. No open conversion was necessary. No major postoperative morbidity and no cases of mortality occurred. The mean hospital stay and resumption of normal diet were similar to those of non-obese patients. Regardless of the higher postoperative risks after open cholecystectomy in obese patients (pulmonary complications, thromboembolism, wound infections and cardiovascular complications), we suggest VLC as the procedure of choice for cholecystectomy in these patients.

The ultrasound scissors are recently emerging as an alternative surgical tool for dissection and haemostasis and have been extensively used in the field of minimally invasive surgery. We studied the utility and advantages of this instrument compared with electrocautery to perform axillary dissection. The operative and morbidity details of thirty-five breast cancer patients who underwent axillary dissection using the ultrasound scissors were compared with 35 matched controls operated with electrocautery by the same surgical team. There was no significant difference in the operating time between the ultrasound scissors and electrocautery group (36 and 30 mins, p>0.05). The blood loss (60 +/- 35 ml and 294 +/- 155 ml, p
