RESUMO

COVID-19 pandemic had an impact on surgical activities. The aim of this multi-centric, retrospective study was to evaluate the impact of the COVID-19 pandemic on breast surgery. The patients who operated during the pre-pandemic year 2019 were compared to those operated in 2020. Fourteen Breast Care Units provided data on breast surgical procedures performed in 2020 and 2019: total number of breast-conserving surgery (BCS), number of 1st level oncoplastic breast surgery (OBS), number of 2nd level OBS; total number of mastectomies, mastectomies without reconstruction, mastectomies with a tissue expander, mastectomies with direct to implant (DTI) reconstruction, mastectomies with immediate flap reconstruction; total number of delayed reconstructions, number of expanders to implant reconstructions, number of delayed flap reconstructions. Overall 20.684 patients were included: 10.850 (52.5%) operated during 2019, and 9.834 (47.5%) during 2020. The overall number of breast oncologic surgical procedures in all centers in 2020 was 8.509, compared to 9.383 in 2019 (- 9%). BCS decreased by 744 cases (- 13%), the overall number of mastectomies decreased by 130 cases (- 3.5%); mastectomy-BCS ratio was 39-61% in 2019, and 42-58% in 2020. Regarding immediate reconstructive procedures mastectomies with DTI reconstruction increased by 166 cases (+ 15%) and mastectomies with immediate expander reconstruction decreased by 297 cases (- 20%). Breast-delayed reconstructive procedures in all centers in 2020 were 142 less than in 2019 (- 10%). The outburst of the COVID-19 pandemic in 2020 determined an implemented number of mastectomies compared to BCS, an implemented number of immediate breast reconstructions, mainly DTI, and a reduction of expander reconstruction.

RESUMO

BACKGROUND: A subsets of ovarian carcinomas (OCs) are related to inherited conditions including Hereditary Breast and Ovarian Cancers (HBOC) and Lynch Syndrome (LS). The identification of inherited conditions using genetic testing might be a strategic model for cancer prevention that include benefits for the ovarian cancer patients and for their family members. METHODS: We describe a retrospective Italian experience for the identification of inherited conditions in 232 patients affected by OCs using both somatic and germline analyses. RESULTS: Immunohistochemical and microsatellite analyses performed on OCs identified 20 out of 101 MMR defective cancers and 15 of these were from patients carriers of the MMR germline pathogenetic variants. BRCA1 and BRCA2 testing offered to 198 OC patients revealed 67 (34%) pathogenetic variant carriers of BRCA1/2 genes. Interestingly LS patients revealed a mean age of OC onset of 45.4 years, which was significantly lower than the mean age of OCs onset of HBOC patients. CONCLUSIONS: Somatic and germline analyses offered to OC patients has proved to be an efficient strategy for the identification of inherited conditions involving OC also in absence of suggestive family histories. The identification of LS and HBOC syndromes through OC patients is an effective tool for OC prevention.

RESUMO

BACKGROUND: Breast angiosarcoma is a malignant mesenchymal neoplasm, which accounts for approximately 2% of all soft tissue sarcomas. Secondary breast angiosarcoma (SBA) may be related to chronic lymphedema after a mastectomy with lymph node dissection (Stewart Treves syndrome) and previous radiotherapy for complications from breast radiation treatment. It is a very rare condition; therefore, diagnosis and management are still a challenge. METHODS: The ANISC collected SBA data by means of a survey sent to all Italian breast centres in the ANISC. The clinicopathological characteristics and the management of this disease were analysed. RESULTS: Twenty-four centres participated in this survey in which 112 cases of SBA were analysed. The median age of the women with SBA was 68.9 years and it appeared approximately 90 months after the first irradiation for breast cancer. In 92% of cases, a mastectomy was performed without axillary dissection for those patients having a high grade of SBA (74.2%). The prognosis was worse in the high-grade cases (overall survival-OS: 36 months) as compared with the low-grade cases (OS: 48 months). After a follow-up of 5 years, 50.5% of the patients were still alive. Disease-free survival (DFS) was 35 months, and there were no differences between the groups of patients with either high- or low-grade histology. CONCLUSIONS: Secondary breast angiosarcoma is a very aggressive disease associated with a short survival outcome. The surgical approach still remains an important step in the course of treatment; furthermore, an accurate histological examination is helpful in establishing the prognosis of the patient. A mastectomy is mandatory. A longer OS was observed in patients with low-grade angiosarcoma as compared to high-grade angiosarcoma (C.I. 40-57 vs. 31-41 months).

RESUMO

INTRODUCTION: The aim of this study was to evaluate the association of breast cancer with thyroid diseases. Many authors have already studied the possible relationship between these two diseases, but the results are nowadays conflicting. MATERIALS AND METHODS: Our study examining 867 patients with breast cancer (862 women and 5 men, average age = 61 years old) of whom 141 also had thyroid disease evaluated the recurrence of thyroid diseases and their association with different types of breast cancer. Statistical analyses were performed using SPSS software for Windows; we used nonparametric tests (Chi-square and Mann-Whitney), and the level of significance was set at p < 0.05. RESULTS: We found a significant association between breast cancer diagnosed after menopause and thyroid disease (p < 0.003). Moreover, we analyzed the role of thyroid autoimmunity identifying an association between chronic autoimmune thyroiditis and breast cancer diagnosed before menopause (p < 0.05). Regarding receptor profile of breast carcinoma, we have found an increased expression of estrogen receptors in patients with autoimmune thyroiditis compared to patients with any other thyroid diseases (p < 0.03). Contrariwise, we do not have found any difference between the group with every thyroid disease and the group without thyroid disease (p < 1.00). We did not find other statistically significant associations with breast cancer's parameters like family history, tumor size, lymph node metastasis, distant metastasis, cancer clinical and pathological stage, differentiation grade and expression of Ki67, p53 and Her2 in the two main groups with or without thyroid disease. Likewise, we did not found other statistically significant association between hypothyroidism or hyperthyroidism and breast cancer.

RESUMO

The p53 transcription factor has a critical role in cell stress response and in tumor suppression. Wild-type p53 protein is a growth modulator and its inactivation is a critical event in malignant transformation. It has been recently demonstrated that wild-type p53 has developmental and differentiation functions. Indeed an over-expression of p53 in tumor cells induces asymmetrical division avoiding self-renewal of cancer stem cells (CSCs) and instead promoting their differentiation. In this study, 28 human breast carcinomas have been analyzed for expression of wild-type p53 and of a pool of non-clustered homeobox genes. We demonstrated that orthodenticle homolog 1 gene (OTX1) is transcribed in breast cancer. We established that the p53 protein directly induces OTX1 expression by acting on its promoter. OTX1 has been described as a critical molecule for axon refinement in the developing cerebral cortex of mice, and its activity in breast cancer suggests a synergistic function with p53 in CSC differentiation. Wild-type p53 may regulate cellular differentiation by an alternative pathway controlling OTX1 signaling only in breast cancer cells and not in physiological conditions.

RESUMO

BACKGROUND AND AIM: Different studies underline the importance of hospital stay on the development of infectious complications. We performed an audit of surgical site infections (SSI) after thyroidectomy was performed in a one-day surgery setting. MATERIALS AND METHODS: One hundred and twelve consecutive patients admitted between April 2007 and discharged before May 2008 were studied. Patient selection criteria for one-day surgery were specific medical and social-logistic status. The technique of thyroidectomy was standardized. RESULTS: SSI affect 2.6% of patients undergoing thyroid surgery with short hospitalization. The incidence of SSI was 3.2% following thyroidectomy, 2% for lobectomy. Mean time interval to symptom onset was 3 days (range 2-6). Most likely organism was Staphylococcus aureus. WI was associated with prolonged ambulatory medications. CONCLUSIONS: Rates of SSI are similar to those described in the literature with longer hospitalization. All SSI become evident only after patient discharge. Prevention of SSI is very much the responsibility of the persons working in the operating theater. Effort should be made to improve sterile technique. Appropriate antibiotic coverage is indicated when infection develops postoperatively.

RESUMO

Day-surgery setting allows to combine patients' satisfaction to cost-saving policies that seems to be more and more important for a modern hospital management. Minimally invasive surgery seems to be the ideal surgical approach for day-case procedures since, reducing trauma to a minimal level, allows patients to return quick to a normal life with minimal nursing assistance. Extensive review of the most recent article has been performed in this article in order to define the current evidences that support the use of laparoscopic surgery in a day-case setting. Laparoscopic cholecystectomy, anti-reflux procedure and hernia repair seems to be justified according to the results of the published data. Patients' selection and hospital organization seem to be mandatory in order to obtain successful results.

RESUMO

BACKGROUND: The study describes the initial experience and learning curve of intraoperative neuromonitoring (IONM) during thyroidectomy. We describe the prevalence and patterns of IONM technical problems. METHODS: Prospective series of 152 consecutive thyroid operations (304 nerves at risk) were analyzed. Standard technique consists of monitoring vagal and RLNs before, during and after resection. Personal gain of experience was defined by the preceding number of thyroid operations. To establish the number of thyroidectomies required before achieving an effective and safe IONM technique, all of the procedures were divided into three chronological groups of about 50 cases (groups 1, 2, and 3). RESULTS: Patients (90%) had successful IONM with initial endotracheal tube position. Fifteen patients (10%) needed further tube adjustment. Out of 15 patients 14 (93%) were due to non-optimal contact of endotracheal surface electrodes to vocal cords. Tube malrotation was the main reason for initial failure (53%). The success rates of prompt IONM technique were 80% in group 1, 92% in group 2, and 98% in group 3 (p<0.05). Mean operating time was low in group 3 (p<0.03). Vagus and RLNs were localized and monitored in all the cases (100%). The incidence of temporary RLN injury was 2.6%. No permanent complications occurred. Negative EMG response indicated an altered function of RLN and stage thyroidectomies were scheduled. Transient RLN palsies were seen without changes during the entire study period. CONCLUSIONS: This is the first series of thyroidectomies with standardized IONM technique performed in Italy. Neuromonitoring was effective in providing identification and function of laryngeal nerves. IONM successful rates were affected considerably by the extent of surgical and anaesthesiological experiences, starting with relatively low rates in the beginner group and then increasing. We assessed the learning curve: improved operative variables and safe technique were seen in about 50 patients.

RESUMO

All over the World laparoscopic cholecystectomy is the treatment of choice for symptomatic cholelithiasis; use of local long lasting anesthetics reduces post-operative pain. Levobupivacaine is one of the most effective local anesthetics. The aim of our study is to test the effectiveness of local anesthetics comparing pre- versus post-operative trocar site's infiltration. 50 patients were enrolled in our study and 25 five patients were randomized into pre-I group (pre-incisional infiltration) and 25 into post-I group (post-operative infiltration); all the operations were performed with the same technique (Anglo-Saxon with 4 accesses) by 4 expert laparoscopic surgeons; our results showed different analgesic consumption between the 2 groups of patients; in the pre-I group the mean intravenous dose of Ketorolac post-operative used was 124 mg while in the post-I group was 339 mg: this difference was statistically significant.; the mean VAS was 10.7 in the post-I group while in the pre-I group was 5.1, also the i-VAS score's difference was statistically significant: in fact in the post-I group i-VAS was 8.8 while in the post-I group 14.8. Our study demonstrated that infiltration of the trocar site with long lasting local anesthetic is extremely effective for the treatment of post-operative pain after laparoscopic cholecystectomy; pre-incisional local infiltration seems to be better in term of pain perception and intravenous post-operative analgesic consumption.

RESUMO

AIM OF THE STUDY: To review the current indications, to establish predictive factors of success and the safety of LC as a day-surgery procedure. METHODS: Randomized clinical trials were searched on PubMed between January 2000 and June 2008 using "laparoscopic cholecystectomy", "day-surgery" as keywords. RESULTS: A total of 20 trials was identified and analyzed. The indications for LC in day-surgery unit were symptomatic and chronic cholelitiasis without evidence of common bile duct stones; acute cholecystitis and pancreatitis cases were excluded. The trials considered as inclusion criteria: ASA score, BMI, social aspect and the preoperative workout included: abdominal US, liver function tests and routine preoperative tests, while the results considered the reasons for hospital stays and for readmission and measured patient satisfaction; some trials included analyze of costs of LC as day-surgery procedure the role of the surgeon's experience. DISCUSSION: The present study confirms that day-surgery LC is safe and feasibility in selected patients; serious complications are rare and most frequently prolonged hospital stay and the readmission are connected with minor and more easily controlled complications or social reasons. Outpatient surgery requires careful planning and preparation in order to reach acceptable patients' satisfaction: preoperative workout is extremely imports allowing to reduce errors selection. Considering surgical training, it has been demonstrated that in the centres in which the trainees are involved in day-surgery LC there not significant difference in terms of number of complications, patient outcomes, prolonged stay and readmission. The adequate control of pain, nausea or vomiting is essential component in day-case LC service and it is possible at home after LC. CONCLUSION: Day-case laparoscopic cholecystectomy is feasible with an acceptable discharge rate and level of patient satisfaction. The success depends on appropriate patient selection and on well-trained staff and skilful operative technique together with safe anaesthesia.

RESUMO

BACKGROUND AND AIM: Evidence base data have demonstrated that video-assisted thyroidectomy (VAT) has good results regarding safety, morbidity, patient cure rate, pain and cosmesis. Aim of this study was to evaluate the performance of VAT in an ambulatory setting (i.e. one-day surgery, <24-h stay). MATERIALS AND METHODS: Between September 2007 and July 2008, 43 patients underwent VAT in a one-day surgery division. Patient selection criteria for VAT were: thyroid nodules <30 mm, gland volume <20 ml, no history of thyroiditis or neck surgery or irradiation, "low risk" papillary carcinoma and absence of enlarged lymph nodes. One-day surgery patient selection criteria were medical and social logistic (Materazzi G, et al. Eur Surg Res 2007;39:182-8). Intraoperative neuromonitoring (IONM) was used for RLN identification. Intact parathyroid hormone (iPTH) levels were determined early postoperatively at +6-h. Postoperative complications, conversion rate were analyzed. RESULTS: No cases required conversion to open surgery or ordinary recovery (i.e. >24h). Incidence of temporary hypoparathyroidism was 11.6% (5/43) with no case of symptomatic hypocalcemia. Incidence of temporary RLN injury was 2.3% (1 patient) with no case of permanent or bilateral RLN injury. All patients were satisfied with the type of recovery. CONCLUSIONS: This preliminary report is an example of the safe incorporation between new technologies (IONM, early iPTH measurement) with improvement of the quality and safety of VAT performed in a one-day surgery setting.

RESUMO

The number of outpatient surgical procedures performed in hospitals increases daily. In some countries, outpatient operations outnumber inpatient operations. The incidence of thyroid disorders and in particular, the cancer forms, has been increasing sharply for many years in several countries. Even if thyroid surgery is performed with low morbidity, no mortality, and short operation time, some potentially lethal complications are strong arguments against shortening of hospital stay. The purpose of this review is to examine the relevant updated published results on selection criteria measures that can be used to assess patients referred to short-stay surgery for thyroid disease.

RESUMO

BACKGROUND AND AIM: Amyloidosis refers to a variety of conditions in which amyloid proteins are abnormally deposited in organs and/or tissues. Amyloidosis is a rare occurrence in thyroid gland. METHODS: A systematic review of the published data on amyloid goiter was carried out by searching Medline and other online databases (such as Scopus and Endnote) for the period from 1951 to March 2008. A total of 127 publications (case series, single case reports and reviews) was found, of which 31 were case series published from February 1995 to March 2008. Six articles have been considered for our review because they regard amyloid goiter as a manifestation of both primary and secondary amyloidosis (a total of 30 cases have been analyzed). Exclusion criterion was the presence of primary thyroid cancer. RESULTS: The preoperative diagnosis of amyloid goiter should be considered in patients with known systemic amyloidosis or with a long-standing predisposing disease who present a rapidly growing thyroid volume in association with a euthyroid state. Fine-needle aspiration biopsy can be performed to exclude primary malignant lesions of thyroid gland and immunohistochemical studies can identify and characterize the amyloid deposits. CONCLUSION: Amyloid goiter has to be suspected in all patients with a progressive, rapidly growing, bilateral thyroid enlargement and a concomitant history of chronic inflammatory processes. Moreover, this should be suspected in patients who are known to have disease predisposing to amyloid deposition.

RESUMO

Thyroid operations are increasingly performed in the outpatient setting. In general the essential objectives for thyroidectomy are: sparing the parathyroid glands, avoidance of injury to the laryngeal nerves, an accurate hemostasis and an excellent cosmesis. In the last 10 years major improvements and new technologies have been proposed and applied in thyroid surgery; among these mini-invasive thyroidectomy, new devices for achieving hemostasis and dissection, intraoperative neuromonitoring, and PTH assay technology. This paper reviews relevant medical literature published on the influence of these new technologies on quality of thyroid surgery as well as prevention of postoperative morbidity and mortality. Searches were last updated April 2008.

RESUMO

BACKGROUND AND AIM: Several studies have demonstrated that endoscopic thyroidectomy is a safe technique. Aim of the study is to evaluate the feasibility of video-assisted thyroidectomy (VAT) performed by a junior surgeon. MATERIALS AND METHODS: We consider 67 consecutive standard VAT gasless approaches. VAT was performed by an under 35-years-old surgeon trained in basic laparoscopy tutored by an experienced surgeon. Outcome measures were operative and hospitalization times, incision length, and complications. Conversion to open surgery was defined as the need to perform a longer incision. To establish the number of procedures required before achieving a safe VAT technique, procedures were divided into three chronological groups of about 30 lobectomies (Groups 1, 2, and 3). RESULTS: Success rates of VAT were 90% in group 1, 97% group 2, 100% group 3 respectively (P<0.05). Most conversions were due to bleeding. In group 1, the overall mean operative time was 111 min, group 2, 93 min, group 3, 86 min (P<0.03). Mean length of incision significantly increased from the initial incision: group 1, +1.3 cm, group 2, +0.9, group 3, +0.5 cm (P>0.05). Group 3 had a faster recovery after surgery. The incidences of temporary hypoparathyroidism were 8.9%. The incidences of temporary RLN injury were 2.9%. CONCLUSIONS: To date there are no recommendations regarding the amount of endoscopic training required to safely perform VAT, but our experience demonstrated that surgeon's age cannot be considered having a negative effects on results. Success of VAT technique was considerably associated with experience: improved operative variables and safe technique were seen after 30 lobectomies.

RESUMO

BACKGROUND AND AIM: Enteric fistulas are defined by their sites of origin, communication and flow. We evaluate the treatment of complex patients with entero-cutaneous fistulae with large abdominal wall defects. MATERIALS AND METHODS: Retrospective case note review of 19 patients (15 males, median age 46 years) treated at the Department of Surgical Sciences, University of Insubria, Varese, Italy. These were distinguished by multiple/wide gastrointestinal fistula orifices, with total discontinuity of bowel. Fistulas were not covered by abdominal wall thus presenting with a giant abdominal wall defects. Surgery was planned once adequate nutritional status was present. RESULTS: All fistulas resulted from previous surgery for IBD in 7 cases (37%), abdominal trauma 4 (21%), acute necrotic infected pancreatitis 3 (16%), intra-abdominal malignancy 3 (16%), and diverticular disease 2 (10%). The most common site of presentation was ileum (80%). Median fistula output was 800ml/day (range 400-1600ml/day). Seltzer's prognostic index identified malnutrition in 70% of patients at the time of presentation. The elapsed mean time from onset of fistula and elective time of surgical management were 184 days (range 20-2190 days). The VAC system was used in the last 7 patients preoperatively and in 6 patients with postoperative abdominal wound dehiscences that could not be closed immediately and who were at high risk for healing complications. There were no complications from the VAC therapy. Surgery was successful in 69% of cases. Mortality rate was 21%. Factors related to mortality were persistent malignancy, malnutrition and sepsis. CONCLUSIONS: After optimization of nutritional status surgery with en bloc resection of fistula offers best results. In this series, cancer and sepsis were unfavourable factors for outcome. These fistulas may be successfully managed with a multidisciplinary approach.

RESUMO

Since the first report in 1991 the laparoscopic resection of colon cancer is progressing slowly and just in the last 2-3 years is becoming more popular. The resistance to its use by some general and colo-rectal surgeons is receding. The explanations are that technology is evolving quickly and there is a worldwide diffusion of more sophisticated surgical instruments. Moreover several randomized trials have been published showing that the outcomes of laparoscopic colon surgery are similar or better than those of conventional surgery and the early reports suggesting the tumour dissemination were not confirmed. The revolution in oncological surgery that we are observing in these last decades with the introduction and diffusion of mini-invasive approach is comparable to that regarding conventional surgery during the period of Halsted. Therefore the principles of surgery accepted during the years must not be forgotten.

RESUMO

Colonic stents potentially offer effective palliation for patients with bowel obstruction attributable to incurable malignancy, and a "bridge to surgery" for those in whom emergency surgery would necessitate a stoma. Literature search of the Medline, Scopus and Cochrane Library was performed to identify comparative studies reporting outcomes on colonic stenting and surgery for large bowel obstruction; and to identify the use of stents as a "bridge to the elective surgery". Colorectal stenting can be considered a safe and effective procedure with a low mortality and morbidity for both preoperative and palliative decompression of colonic obstruction.

RESUMO

INTRODUCTION: Several randomized controlled trials demonstrated that laparoscopic colon resection is a safe and effective technique for colon and rectum diseases. In fact mini-invasive procedure required an adequate learning curve to safely perform it. Many studies confirm there is a comparatively long learning curve in laparoscopic surgery, with demonstrable decrease in conversion and complication rates with increasing experience. AIMS OF THE STUDY: In this study we want to demonstrate feasibility of laparoscopic colon resection performed by a junior surgeon, referring to short-term outcomes as primary end point. RESULTS: A total of 163 patients underwent colorectal resections of whom 88 were enrolled in the laparoscopic (LCR) and 75 in the open group, respectively. The mean operative time was 183.4 min in the LCR group and 151.2 min in the open group. The mean number of lymph nodes collected was 21.3 in the LCR group and 22.1 in the open group. 10.5% who underwent LCR developed postoperative complications compared with 16% of open group; this difference was statistically significant. Postoperative death occurred in one patient for each group. CONCLUSIONS: Our study demonstrate that results obtained by an under 35-year-old surgeon, fully trained in laparoscopic surgery but with limited overall experience in colorectal resections, can be at least as good as the ones obtained in open surgery. This seems to be true both in term of intra-postoperative complications as well as for oncological results.
