RESUMO
BACKGROUND: Redo surgery for recurrent goiter is still now, even in experienced hands, followed by higher morbidity than primary total thyroidectomy. Suppressive Levothyroxine therapy failed to improve the recurrence rate, while inducing a subclinical hyperthyroidism. Aim of this study is to verify morbidity after total thyroidectomy for benign thyroid diseases, both primary and after recurrence. MATERIALS AND METHODS: A series of 20 cases of total thyroidectomy for recurrent benign diseases (RG), performed between January 2001 and December 2013 was compared with 225 cases of primary total thyroidectomy (PT) . Cancers, even incidentally diagnosed, were excluded. At least a 12 months follow up was accomplished. Due to the small size of the sample for RG, statistical analysis was performed by Fisher test only. RESULTS: Postoperative complications were Transient hypocalcemia: 5 (25%) in RG and 18 (8%) in PT, Permanent hypocalcemia only 2 (10%) in RG (significant for p <0,05), Transient RLN deficit 5 (25 %) in RG and 6 (2.6%) in PT (significant for p< 0.05). CONCLUSIONS: Differences in incidence of perioperative complications cannot be advocated to justify a less than total thyroidectomy even in benign disease setting. The need for a redo surgery with its burden of morbidity is per se a good reason to avoid a conservative surgery. Further, suppressive therapy with Levothyroxine often fails to avoid recurrence, inducing in some cases a specific morbidity. Our experience confirms the results of our previous experiences and of literature on this topic: the best management of recurrent goiter is its prevention by primary total thyroidectomy.

OBJECTIVE: To evaluate the oncologic safety of colonic self-expandable metal stents (SEMS) in obstructive colon cancer. PATIENTS AND METHODS: We retrospectively reviewed all the patients who were treated with endoscopic placement of a self-expandable metallic stent (SEMS) at our institution. RESULTS: A total of 26 patients were identified during the study period, of which 24 patients (92.30%) were treated with SEMS as a bridge-to-surgery and 2 (7.69%) as palliation. In 22 cases (80.76%), the stenosis was localized to the left side. Clinical success with resolution of bowel obstructions was achieved in 22 (84.61%) patients within a short period of time. Among patients treated successfully with SEMS insertion as bridge to surgery (n = 22), 20 (90.9%) underwent one-stage surgery with primary anastomosis while 2 patients (9.09%) underwent colostomy due to intraoperative evidence of a covered perforation by cancer tissue in the pelvis. Patients with subclinical perforation developed an early peritoneal carcinomatosis, 10 patients treated with curative intent subsequently developed liver metastasis after 24 months. CONCLUSIONS: We reported an overall poor outcome among patients treated with the insertion of SEMS. This led us to think that, in some cases, occlusion may be better than a "silent" perforation.

INTRODUCTION: Pseudocyst formation commonly follows pancreatitis, but erosion into the spleen is rare and potentially life threatening. We report a case of an intrasplenic pancreatic pseudocyst treated laparoscopically with distal pancreatectomy and splenectomy. METHODS: A 50 year old male with a history of chronic alcoholic pancreatitis, presented with abdominal pain for 3 months, worsening over the past several days. A CT scan showed a broad 9 cm subcapsular fluid collection suspicious for an intra-splenic pseudocyst. The patient underwent laparoscopic distal pancreatectomy and splenectomy. RESULTS: There were no intraoperative complications and the patient was discharged on day 8. The final pathology revealed a benign cystic lesion measuring 9 x 6 x 3 cm that was not communicating with the pancreatic duct, and 2 smaller pseudocysts in the pancreatic body and tail. A previous scan did not reveal any abnormalities in the spleen, and showed the other pancreatic pseudocysts. At 8 month follow up the patients was symptom free, with no new pseudocysts. CONCLUSIONS: Splenic parenchyma involvement is an unusual complication of pancreatic pseudocyst. The optimal treatment is controversial. Percutaneous drainage carries a high recurrence rate and risk of hemorrhage. Open surgery is effective, but associated with significant morbidity. Laparoscopy offers an effective method of treatment without the potential complication of a large abdominal incision.

OBJECTIVE: The widespread use of laparoscopy has changed the outcome of gallbladder cancer as a consequence of increasing referral and incidental discovering of earlier stages cancer. Nevertheless, GBC is still associated with a poor prognosis and lymphnodal involvement is a main prognostic factor, important both for staging and for evaluating surgery quality. No consensus exists about the extension of lymphadenectomy to be performed nor about contraindications to extensive resection. A review of literature was so designed to identify the actual role, extension and limits of lymphadenectomy. MATERIALS AND METHODS: A search on Pubmed and Scopus has been performed using the following keywords: gallbladder cancer, gallbladder neoplasm, surgery, laparoscopy, lymphadenectomy to evaluate the prognostic and the therapeutic role of the lymphadenectomy in gallbladder cancer. The retrieved articles were analyzed aimed to evaluate the impact of lymphectomy and of its extension on overall and disease free survival. RESULTS: Although no consensus still exists over the extension of ideal lymphadenectomy, some points are already clearly established: a part from T1a neoplasms, that do not require further surgery, and T1b for which a regional lymphectomy (N1) is safe and mandatory, more advanced stages require a more aggressive surgery but the fate of paraortic nodal station is still under evaluation. In fact some Authors still believe that the involvement of these nodes determine a so poor prognosis to make uselessly risky their surgical aggression. Other Authors conversely, show that there is not any difference in survival, among node positive patients, between paraortic node positive and no paraortic node positive patients. CONCLUSIONS: The prognosis of gallbladder cancer remains poor because in most patients the diagnosis is made at an advanced stage. Complete surgical resection provides the only curative treatment option in this disease. In order to improve long-term outcome, several surgeons have advocated aggressive surgical resection, including major hepatectomy, pancreatoduodenectomy and extended lymphadenectomy. Even a para-aortic nodal disease shouldn't discourage from pursuing this objective.

OBJECTIVE: Nowadays, laparoscopic cholecystectomy (LC) is undoubtedly considered the "gold standard" in the surgical treatment of symptomatic gallstones, gallbladder adenomas and acute cholecystitis. Among the alternative energy sources proposed (monopolar, bipolar electric scalpel, radiofrequency sealers) with the aim to dissect and/or seal, the ultrasonic energy has been frequently adopted, however without a widespread acceptance among surgeons for routine or emergency laparoscopic cholecystectomy. This study investigates the possible beneficial aspects of ultrasonic dissection and its efficacy in the closure of the cystic artery and duct. PATIENTS AND METHODS: Patients were retrospectively divided into 2 groups according to the instruments used for division of the cystic artery and duct as well as for dissection of the liver bed: 121 patients in whom dissection and coagulation were performed using monopolar coagulation and 43 patients who were all treated with the ultrasonically activated scalpel harmonic ACE (Ethicon Endo-Surgery) as the sole instrument used in the whole procedure. RESULTS: The mean operative time, was significantly shorter in the harmonic group than in the traditional group (35.36 + 10.15 min vs. 55.6+12.10 vs. respectively; p < 0.0001). The rate of gallbladder perforation was significantly higher in the traditional group than in the harmonic group 20.66% (25 patients) vs. 6.98% (3 patients), respectively; p < 0.05). Intraoperative volume blood loss was significantly more in the traditional group than in the HS group (29.32+14.21 vs. 12.41+8.22; p < 0.0001). The mean amount of postoperative drainage was not significantly different among the two group (18.41+6.54 vs. 15.96+8.69 ml, p > 0.05). No considerable visceral injury has been recorded in either group. The postoperative parameters observed included postoperative hospital stay and morbidity for each group. The hospital stay was not significantly shorter in harmonic group (48.15+4.29 vs. 49.06+2.94 h, p > 0.05). The overall morbidity rate was 14.02 % (not significant). CONCLUSIONS: The use of the harmonic scalpel shows some statistically significant advantages limited to a few intraoperative parameters. We conclude that a wider use of harmonic scalpel not offers such advantages to make it the reference technique.

PURPOSE: The purpose of this systematic review is to evaluate and compare the risk of dissemination metastasis (wound, port-side metastases and peritoneal seeding) after laparoscopic colorectal surgery and conventional open surgery for colorectal cancer. MATERIALS AND METHODS: The Authors searched relevant randomized controlled trials between January 1998 and July 2012. RESULTS: Wound, port-site metastases and peritoneal seeding were rare and no significant differences occurred between the two groups. The port-site and extraction site recurrence were likely to be the results of suboptimal surgical techniques and occurred in the early phase of the learning curve. The authors also found no significant differences in overall, local and distant recurrences. No significant differences between laparoscopic and open surgery were found in cancer-related mortality during the follow up period of the study (7 RCTs, 3525 patients, 12.8% vs. 14.00%; OR (fixed) 0.83, 95% CI 0.68-1.02), with no significant heterogeneity (p = 0.35). CONCLUSIONS: The literature supports the implementation of laparoscopic surgery into daily practice. Laparoscopic surgery can be used for safe and radical resection of cancer in the right, left, sigmoid colon and rectum. However further studies should address whether laparoscopic surgery is superior to open surgery in this setting.

INTRODUCTION: Squamous cell carcinoma of the anus (SCCA) is a relatively uncommon cancer. In the HIV-positive patients the introduction of the highly active antiretroviral therapy (HAART) did not change the incidence of SCCA. BACKGROUND AND OBJECTIVES: This paper describes the Italian Cooperative Group on AIDS and Tumours (GICAT) experience on HIV-positive patients with SCCA. The purposes of this retrospective study were: first to describe the clinical presentation and outcome of HIV-positive patients with SCCA, second to compare them with the ones reported in the literature. PATIENTS AND METHODS: Between July 2000 and March 2010 we retrospectively collected epidemiological, clinical and survival data from 65 patients with SCCA in HIV infection enrolled within the GICAT. RESULTS: Fifty-three (81.5%) patients were male. The majority of patients (40%) were homosexual Forty-three patients (66.1%) were diagnosed with HIV before 1996. Thirty-five patients (54%) had CD4-positive cells count > 200 / mm3 and 28 patients (43%) had viral load > 50 cp / ml at the time of SCCA diagnosis. The median time difference between HIV and SCCA diagnosis was 120 months (range 10-282 months). Sixty-one patients (96.8%) received HAART at SCCA diagnosis. Fifty-two patients (80%) had performance status (PS) 0-1 at the time of SCCA diagnosis. Twenty-seven patients (41.5%) underwent surgery with curative intent. Thirty-five patients (53.9%) were given combined modality therapy (CMT) consisting of pelvic radiotherapy with concurrent chemotherapy. No grade 3/4 haematological or extra-haematological effects were observed in our patients. CONCLUSIONS: In summary, despite the retrospective nature of analysis, the absence of patient strict criteria of inclusion/exclusion, our data on HIV-positive patients with SCCA, compared both to general population and to small reports on HIV-positive patients present in the literature, are promising.

Among adrenal masses only 0.06% to 0.18% are cysts and among them, pseudocysts are the second (39%) most common lesions. Due to the increased use of imaging studies their incidence seems to have increased. Most of these lesions are incidentally found during radiologic investigation or at the time of autopsy, and only rarely they are detected in pregnant women. The latter scenario warrants emergency surgery, due to the risk of rupture. We present a case of a 39-years old woman presenting with unrelenting left flank pain due to a large adrenal pseudocyst soon after her first delivery. Four months after, she presented to our surgical division for persistent pain and anemia so underwent an extensive work up that showed a large pseudocystic mass (8 x 8 cm ) of the left adrenal gland. Once the neoplastic and parasitic etiology of the lesion were excluded, she underwent uneventful laparoscopic adrenalectomy. She was discharged home three days postoperatively. This case is the 13th case in the English literature and at the same time is the first case of adrenal pseudocyst occurred four months after delivery.

UNLABELLED: BACKGROUND, OBJECTIVES: Pancreatic cancer ranks fourth for cancer mortality for men and women in the United States. This is a particularly devastating cancer since the case-fatality proportion approaches 90% within 12 months following diagnosis. Therefore, understanding the etiology and identifying the risk factors are essential for the primary prevention of this deadly disease. Of the few potentially modifiable risk factors that have been identified, cigarette smoking, history of diabetes mellitus, and obesity seem to be among the most consistent, but the effect of dietary factors is still unclear. The aim of our study is to review of the literature examining the potential role of carbohydrates, fatty acids, meat, fruit and vegetables, alcohol. DISCUSSION: Although large prospective cohort studies with questionnaire based analyses will continue to have much to offer in defining predisposing factors for difficult diseases, such as pancreatic cancer, unfortunately dietary questionnaires do not reflect the bioavailability of the nutrients from various foods, the level of absorption from the digestive tract, or individual differences in metabolism. CONCLUSIONS: Greater use of participant-derived biological samples, banked plasma, germline DNA, and tumour tissue samples may help to the understanding of pancreatic cancer pathogenesis.

Urachal cysts are usually asymptomatic. Symptoms, when present, are usually acute abdominal pain, fever, midline hypogastric tenderness, palpable mass, evidence of urinary infection or haematuria due to infection of the cyst. We report an unique case of dyspareunia and "abdominal fluid flowing feeling" caused by an urachal cyst in a 28 year-old nulliparous woman. Diagnosis was achieved by US and MRI. Cystography excluded any cyst-bladder communication. Laparoscopic surgery was performed without perioperative complications. Patient obtained immediate relief of symptoms still continuing at a 24 months follow up.

Gallbladder metastasis of breast cancer are rare, particularly linked to lobular histotype and synchronous just in 1/4 cases. A review of the literature has been performed aimed to evidence the patterns of gallbladder metastases of breast cancer finding 15 cases to whom we added a 48 years old post-menopausal woman. 3 weeks after surgery for mixed ductal-lobular breast carcinoma she showed at the abdominal ultrasound, performed for staging, diffuse thickening of the gallbladder wall , coherent with a chronic cholecystitis and with the mild right-upper-abdominal pain that the patient complained in the last months. After laparoscopic cholecystectomy, the pathology report showed a metastatic lobular carcinoma of the breast. Two years later she presented with SNC metastases and died four months later. Lobular histotype is the most frequent breast neoplasm associated with gallbladder metastases. Usually metachronous, these metastases are sinchronous in 28% of cases. Symptoms are usually linked to coexisting acute or cronic cholecystitis. Rarely massive invasions lead to acute abdomen or jaundice. Imaging is rarely diagnostic for neoplasm. Our experience and data from literature lead to careful evaluate every anomaly observed in breast cancer patients. A careful evaluation of abdominal symptoms and of routine imaging examinations performed for staging and for treatment planning, could consent to detect and radically treat the metastases and appropriately assign the chemotherapy. Such approach can lead to discrete survival even in these unfortunate patients. Surgeons and gastroenterologists should be aware of the risk hidden behind apparently benign, mild diseases in such patients.

Hemorrhoidal disease is a frequent cause of morbidity among the general population with a reported incidence of 4.4%, but little is known about its incidence and clinical features in kidney transplant recipients. Among 116 patients who had undergone kidney transplantation and were evaluated for hemorrhoidal disease, 82 had no hemorrhoids (70.6%), 28 (24%) had grade I hemorrhoids, and 6 (5.4%) had grade II hemorrhoids at the pretransplantation evaluation. Twenty-seven out of 116 recipients (22.4%) developed grade III or IV hemorrhoids after transplantation and underwent surgery. Hemorrhoidal disease was more frequent in patients with a pretransplantation history of hemorrhoids, with a rapid weight increase in the posttransplantation period, or who were aged between 30 and 50 years. Immunosuppressive therapy may play an important role in the worsening of hemorrhoidal disease among kidney transplant recipients. A prompt diagnosis and surgical treatment, whenever necessary, is mandatory for patients with clinical signs of worsening of hemorrhoids.

The purpose of this study was to evaluate the feasibility and the activity of radiotherapy treatment in patients aged ≥75 with prostate cancer (PC). From January 2000 to December 2007, 107 consecutive patients aged ≥75 years received radiotherapy with radical intent for PC. Eighty-one patients received radiotherapy in combination with a 6 months androgen suppression therapy. Variables considered were age, stage, co-morbidities according to the adult co-morbidity evaluation index (ACE-27) and performance status (PS). The median age was 79.1 years (range 76-87). The 23.4% of patients showed no co-morbidities, while the 46.7% had mild, 23.4% moderate, and 6.5% severe co-morbidities, respectively. All patients completed the planned radiation treatment. At a median follow-up of 37.8 months, the 5-year overall survival rate was 78%. There was a better survival for patients with no or mild co-morbidities (p<0.0001) and a good PS (p=0.009). The actuarial disease-free survival at 60 months was 75.8%. Difference in acute and late toxicity rate was detected between ACE-27 classes for diarrhea and marginally for urinary toxicity, but no difference was detected for different age. We conclude that compliance with radiotherapy is good and rate of toxicity is acceptable in elderly patients. Increasing severity of co-morbidity may sufficiently shorten remaining life expectancy to cancel gains with radical radiotherapy. Further prospective trials are needed to confirm these results.

This study presents the results of the italian "Severe infections project" involving bacteria that can be considered rare causes of disease. we isolated 30 uncommon human pathogens from a total of 60 strains (1.2% of all the isolates). The most frequent sources of uncommon human pathogens were primary bloodstream infections (48.3%) and pneumonia (20%). Species such as Comamonas testosteroni, Enterococcus hirae, Kluyvera ascorbata, Kluyvera cryocrescens, Leclercia adecarboxylata and Ochrobactrum anthropi were recovered from bacteremia patients. Clinically useful antimicrobial agents were tested against each isolate. Resistance to 4 or more antibiotics tested was found in Achromobacter xylosoxidans, O. anthropi, Pseudomonas stutzeri, Citrobacter braakii, Enterobacter sakazakii, K. ascorbata, Proteus penneri and Serratia plymuthica. About 16% of the Gram-negative species were resistant to third-generation cephalosporins and 28.6% of the staphylococci were oxacillin-resistant. the results from this study offer indications for empirical therapy for severe infections from uncommon human pathogens.

INTRODUCTION: Development of cancer after transplantation has rapidly became one of the leading causes of death in kidney transplant recipients with functioning grafts. Anogenital malignant neoplasms may occur with a 14-fold increased incidence, and human papilloma virus (HPV) infection has been recently identified as the leading cause of cervical carcinoma. We report the preliminary findings of a prospective study that evaluated the incidence of HPV infection and cervical carcinoma in a population of kidney transplant recipients. PATIENTS AND METHODS: The study included 35 female recipients of a deceased donor kidney with at least 6 months of follow-up. All patients underwent a cervicovaginal brushing, an HPV DNA test, and a Papanicolaou test. RESULTS: Twenty-two patients (62.8%) were positive for HPV DNA. Thirteen of 22 HPV DNA-positive recipients (59%) demonstrated a high-risk HPV genotype. No cytologic anomalies were detected in Papanicolaou smears. CONCLUSIONS: These preliminary data demonstrated a high incidence of HPV infection in renal transplant recipients. Most of our recipients exhibited a high-risk HPV genotype, which suggests higher aggressiveness of such infection in immunosuppressed patients. The HPV test is useful to monitor patients at higher risk of anogenital malignant neoplasms by identifying the cytologic anomalies at an earlier stage. This ongoing study will investigate the rate of progression of HPV infection and the clinical patterns of HPV-positive cytologic anomalies in renal transplant recipients.

INTRODUCTION: Renal vein thrombosis (RVT) has an incidence of 0.55% to 3.4% and accounts for as many as one-third of early allograft losses. Rarely, RVT may be a consequence of an extension of ipsilateral iliac vein thrombosis. We present a rare case of iliocaval thrombosis as a consequence of inferior vena cava compression by a large-for-size kidney transplant. CASE REPORT: A 20-year-old woman with spina bifida and kidney failure received a living donor kidney from her 52-year-old father. On postoperative day 8, the patient had right lower quadrant abdominal pain associated with oliguria. Graft duplex ultrasonography examination revealed venous thrombosis arising in the right femoral vein and extending to the iliac vein. An urgent second laparotomy was performed, and the kidney was finally placed in the peritoneal cavity. CONCLUSIONS: The eventuality of an inferior vena cava compression by a transplanted kidney should be considered in any recipient with sudden leg swelling and acute graft dysfunction. An early diagnosis and prompt intervention may reduce the progression to RVT and subsequent graft nephrectomy. When planning a kidney transplantation with a supposed size discrepancy between donor and recipient, positioning the kidney on the left side or in the peritoneal cavity may be preferred.
