About 1/10 of the patients apply to breast clinics with the complaint of nipple discharge (ND). Surgery is the most frequently preferred treatment method in case of suspicious ND. The contribution of ductoscopy to identify the patients who are candidates for surgery was evaluated and its role to limit the surgery was assessed. From November 2005 to December 2010 430 patients with ND were assessed by 456 ductoscopic investigations and the results were analyzed. Complete ductoscopic evaluation was achieved in 84% of cases and 28 patients were offered surgery but did not accept (N.=355). Patients with bloody or serous discharges from a single duct were investigated by ductoscopy under local anesthesia as an office procedure. The patients were grouped according to discharge characteristics and the ductoscopic diagnoses. A total of 223 patients had all three criteria of pathologic ND (PND: single duct, spontaneous and bloody/serous discharge). Twenty-two potential neoplastic or malignant lesion (PNML) and 79 papillomatous lesion (solitary or multiple papilloma) were identified. In 132 patients with just two of the PND criteria, 5 PNML and 18 papillomatous lesions were identified. Twenty-three patients with solitary papilloma that were removed by ductoscopic papillomectomy (DP) are followed up without surgery. Ductoscopy helped to identify the patients who required surgical treatment and decreased the number of operations. DP was successfully performed in select group of patients who otherwise would have required surgical resection. Patients with normal ductoscopy findings and patients who were treated with DP successfully can be followed up without the need of surgery.

Diffuse malignant peritoneal mesothelioma (DMPM) is a rare and locally aggressive tumor with poor prognosis, related in most cases to asbestos exposure. It is increasing in frequency, but currently no standard therapy is available. The biology of this disease is still poorly understood. Several highly specialized centers have recently reported improved survival by means of an innovative local-regional approach. The purpose of this article is to evaluate the survival benefit and the morbidity rate of patients affected by DMPM treated at our institution by cytoreductive surgery (CRS) associated with hyperthermic intraperitoneal perioperative chemotherapy (HIPEC). This study includes 42 patients affected by DMPM treated by an uniform approach consisting of cytoreductive surgery associated with HIPEC using cisplatin and doxorubicin. The primary end point was overall survival and morbidity rate. The secondary end point was evaluation of prognostic variables for overall survival. The median follow-up period was 72 months (range 1-235 months). Thirty-five patients (83.3%) presented epithelial tumors and 7 were affected by multicystic mesothelioma. The mean peritoneal cancer index (PCI) was 13. Thirty-eight patients (90.4%) had complete cytoreduction (CC-0/1). The overall morbidity rate was 35.7% associated to a perioperative mortality of 7.1%. Median overall survival rate was 65 months with a 1- and 5-year survival rates of 63% and 44%, respectively. The treatment of DMPM by CRS+HIPEC in selected patients is a feasible technique that allows to achieve encouraging results in terms of overall survival rate, with an acceptable morbidity rate. Further investigations are needed to clarify the role and the timing of this promising technique.

Relations between laparoscopic adjustable gastric banding (LAGB), gastroesophageal reflux (GER) and hiatal hernia (HH) are controversial. In this context the role of preoperative investigations to assess upper gastrointestinal (GI) function and its impact on the approach to LAGB and outcomes remains unclear. The aim was to define the value of preoperative upper GI testing, and to relate the findings with postoperative outcomes. Seventy-eight cases were enrolled among 250 patients undergoing LAGB from January 2010 to December 2011 in our Center for the Multidisciplinary treatment of severe obesity. Patients were submitted preoperatively to endoscopy and radiologic series with oral contrast to assess the state of upper GI mucosa, the presence of HH, GER or cardias incontinence. According to the findings, patients were assigned to group A, if one or both exams showed positive results; or to the control group B if both exams were negative. GI series showed GER in 14.1% of patients, HH in 6.4%, altered motility in 5.1%, gastritis in 3.1%and were negative in 75.6%. Endoscopy showed gastritis in 71.8%of patients, HH in 30.8%, esophagitis in 7.7%, duodenitis in 7.7%, LES incontinence in 8%; while only 21.8% of patients had a negative exam. Differences between group A and B are not statistically significant in terms of pre- and post-operative BMI, EBWL%, long-term complications, time and number of regulations. Positive findings in preoperative testing rarely postpone or change the surgical approach and postoperative outcomes. Our results encourage the omission of upper GI series from routine evaluation protocol prior to LAGB.

The aim of our study was to evaluate, through prospective randomized study, the outcome and the immediate and late complications of the two types of surgery most widely used for degree III-IV haemorrhoids. A total of 122 patients with degree III and IV hemorrhoids were elected for surgical intervention and, randomly, underwent surgery for PPH or THD. We assessed the most common immediate postoperative complications. The patients have been followed for three months with a mean follow-up at 1 month and 3 months after surgery. Parameters taken into consideration were: bleeding, pain at rest and after evacuation, soiling, constipation and tenesmus. Five patients in PPH group (7.9%) had a major postoperative bleeding, whereas no such episode occurred in THD group (P=ns). In percentage terms, VAS score was lower in THD group than in PPH group, although the difference was not statistically significant. Finally parameters values observed, during the follow-up, proved to be lower for THD group compared to PPH group. PPH and THD are two surgical treatments for degree III and IV haemorrhoids with low perioperative complications and good results in the short term. However, our experience shows that better results in terms of pain and fewer postoperative complications are obtained after THD surgery, such surgery is less invasive and more adaptable to the needs of day surgery.

Electromagnetic navigation bronchoscopy (ENB) was reported to increase diagnostic yield in pulmonary nodules (PNs). The aim of this study was to assess if rapid on site evaluation (ROSE) associated with ENB could improve diagnostic accuracy in PNs after non-diagnostic fluoroscopy-guided bronchoscopy added to ROSE. Forty patients with PNs suspected for lung cancer underwent to ENB + ROSE after non-diagnostic Fluoroscopy-guided Bronchoscopy + ROSE. Each lesion was studied with reference to size, location, presence of bronchus sign on CT. All lesions were sampled by needle and brush; if negative, by forceps and bronchoalveolar lavage. All patients were followed-up until achievement of definitive diagnosis. Twenty-nine out of 41 lesions (70.7%) had a definitive diagnosis. ENB sensitivity for malignancy was 76.5%, with higher rate in presence of bronchus sign on CT (86.2%) and in case of lesions located in the upper and middle lobes (87.5%). ENB is a useful tool in the evaluation of PNs. High diagnostic accuracy may be related to sampling (transbronchial needle aspiration), ROSE, location and presence of bronchus sign.

Colorectal cancer is one of the most common malignancies seen in developed countries. Its current treatment is based on a multidisciplinary approach entailing surgery, chemotherapy and radiotherapy. Surgery can be performed with open and minimal invasive methods. Single incision laparoscopic surgery (SILS), natural orifice transluminal endoscopic surgery (NOTES) and robot assisted laparoscopic surgery (RALS) are the final points to be reached in minimally invasive surgery. The first robotic colorectal surgical intervention was performed in 2001 after getting the FDA approval for the da Vinci surgical system in intraabdominal surgery, and since then, its use in this field gradually increased. Compared to open surgery, the advantage and superiority of robotic surgery, especially in narrow areas such as the pelvis, has been shown in many studies. It is a safe and feasible method. Although there are many existing studies about minimally invasive surgery, more randomized studies with larger case numbers should be carried out in order to establish the favorable oncological and functional outcomes of robotic surgery in addition to its obviously observed advantages.

An update on the current status of robotic hepatobiliary surgery based on a review of the available literature. A literature search was performed using the PubMed database with search phrases "robotic hepatectomy", "robotic liver resection", "robotic liver surgery", "robotic hepatobiliary surgery", and "robotic biliary reconstruction". We selected articles with high volume case series or case controlled series. As a result of our literature search we will focus on the 9 major articles on robotic liver resection (RLR) with 235 patients undergoing RLR for a total of 244 liver resections. In addition a brief update on robotic biliary reconstruction will also be presented based on the above articles and recent review articles. Indications for robotic liver resection included both benign (N.=72, 29.5%) and malignant disease (N.=172, 70.5%). The most common indication was colorectal liver metastasis (N.=87, 50.6%) and hepatocellular carcinoma (N.=57, 33%). The most common type of resection was subsegmental (N.=55, 22.5%), with a significant number of major hepatectomies (N.=80, 32.8%). Overall conversion rate was 7.8%, with majority converted to open (N.=18) and one converted to hand assisted. The overall complication rate was 11.8% (N.=29). No perioperative mortality was reported. Preliminary results show that robotic assisted laparoscopic hepatobiliary surgery has materialized as a new technique that combines the advantages of laparoscopy with the dissection, suturing and articulation of robotics. This more closely approximates open surgery. The preliminary data demonstrates that RLR can be applied in major hepatobiliary centers safely. Future comparative studies are needed to determine if this is of significant benefit over current open techniques.
