Real-time near-infrared (NIR) fluorescent cholangiography in single-site robotic cholecystectomy (SSRC): a single-institutional prospective study.

BACKGROUND: Bile duct injury is a rare but serious complication of laparoscopic cholecystectomy and the primary cause is misinterpretation of biliary anatomy. This may occur more frequently with a single-incision approach due to difficulties in exposing and visualizing the triangle of Calot. Intraoperative cholangiography was proposed to overcome this problem, but due to multiple issues, it is not used routinely. Indocyanine green (ICG) near-infrared (NIR) fluorescent cholangiography is non invasive and provides real-time biliary images during surgery, which may improve the safety of single-incision cholecystectomy. This study aims to evaluate the efficacy and safety of this technique during single-site robotic cholecystectomy (SSRC). METHODS: Patients presenting with symptomatic biliary gallstones without suspicion of common bile duct stones underwent SSRC with ICG-NIR fluorescent cholangiography using the da Vinci Fluorescence Imaging Vision System. During patient preparation, 2.5 mg of ICG was injected intravenously. During surgery, the biliary anatomy was imaged in real time, which guided dissection of Calot's triangle. Perioperative outcomes included biliary tree visualizations, operative time, conversion and complications rates, and length of hospital stay. RESULTS: There were 45 cases between July 2011 and January 2012. All procedures were completed successfully; there were no conversions and at least one structure was visualized in each patient. The rates of visualization were 93 % for the cystic duct, 88 % for the common hepatic duct, and 91 % for the common bile duct prior to Calot's dissection; after Calot's dissection, the rates were 97 % for all three ducts. Mean hospital stay was 1.1 days and there were no bile duct injuries or any other major complications. CONCLUSION: Real-time high-resolution fluorescent imaging to identify the biliary tree anatomy during SSRC using the da Vinci Fluorescence Imaging Vision System was safe and effective.

Single-site robotic cholecystectomy (SSRC) versus single-incision laparoscopic cholecystectomy (SILC): comparison of learning curves. First European experience.

BACKGROUND: Single-incision laparoscopic surgery is an emerging procedure developed to decrease parietal trauma and improve cosmetic results. However, many technical constraints, such as lack of triangulation, instrument collisions, and cross-handing, hamper this approach. Using a robotic platform may overcome these problems and enable more precise surgical actions by increasing freedom of movement and by restoring intuitive instrument control. METHODS: We retrospectively collected, under institutional review board approval, data on the first 25 patients who underwent single-site robotic cholecystectomies (SSRC) at our center. Patients enrolled in this study underwent SSRC for symptomatic biliary gallstones or polyposis. Exclusion criteria were: BMI > 33; acute cholecystitis; previous upper abdominal surgery; ASA > II; and age >80 and <18 years. All procedures were performed with the da Vinci Si Surgical System and a dedicated SSRC kit (Intuitive). After discharge, patients were followed for 2 months. These SSRC cases were compared to our first 25 single-incision laparoscopic cholecystectomies (SILC) and with the literature. RESULTS: There were no differences in patient characteristics between groups (gender, P = 0.4404; age, P = 0.7423; BMI, P = 0.5699), and there were no conversions or major complications in either cohort. Operative time was significantly longer for the SILC group compared with SSRC (83.2 vs. 62.7 min, P = 0.0006), and SSRC operative times did not change significantly along the series. The majority of patients in each group were discharged within 24 h, with an average length of hospital stay of 1.2 days for the SILC group and 1.1 days for the SSRC group (P = 0.2854). No wound complications (infection, incisional hernia) were observed in the SSRC group and in the SILC. CONCLUSIONS: Our preliminary experience shows that SSRC is safe, can easily be learned, and performed in a reproducible manner and is faster than SILC.

Laparoscopic gastrectomies for cancer: The ACOI-IHTSC national guidelines.

Guidelines for laparoscopy and cancer of stomach have been outlined by several scientific societies: The main recommendation being that laparoscopy should be used only by surgeons already highly skilled in gastric surgery. The laparoscopic approach to gastric cancer surgery has become more and more frequent in most Italian centers. On behalf of the Guideline Committee of the Italian Society of Hospital Surgeons and the Italian Hi-Tech Surgical Club, a panel of experts analyzed the highest evidence of all scientific papers focusing on laparoscopic gastrectomies for cancer and published from 2003 to 2011, and drew these national guidelines. Laparoscopic gastrectomy may be considered as a safe procedure with better short-term and comparable long-term results. compared to open gastrectomy (Grade A). There is a general agreement that a laparoscopic approach to the treatment of gastric cancer should be chosen only by surgeons already highly skilled in gastric surgery and other advanced laparoscopic interventions. Furthermore, the first procedures should be carried out during a tutoring program. Diagnostic laparoscopy is strongly recommended as the first step of laparoscopic as well as laparotomic gastrectomies (Grade B). Additional randomized controlled trials (RCT) that compare and investigate the long-term oncological outcomes of laparoscopic assisted gastrectomy are required.

Cholangioscopic management of intrahepatic papillomatosis unsuitable for surgical treatment.

INTRODUCTION: Biliary papillomatosis can arise in any tract of the biliary three and is characterized by multiple papillary proliferation of the epithelial cells. CASE REPORT: A 65 year old woman was diagnosed been affected by biliary papillomatosis after many recurrent cholangitis episodes. Liver transplantation was excluded because of neoplastic degeneration with systemic involvement. After a percutaneous drainage and with palliative intent we performed an Argon plasma coagulation of the papillary lesions. DISCUSSION: Clinical behaviour consists of recurrent cholangitis episodes and obstructive jaundice. There aren't specific radiological features, only mucobilia observed during an ERCP is pathognomonic. Biliary papillomatosis grow according to the sequence adenoma-carcinoma with malignant transformation and poor prognosis due to multifocality and high recurrence rate. Radical surgery and liver transplantation represents the gold standard. Among palliative procedures must be considered percutaneous management with drainage and stenting, and intraluminal brachytherapy with I 192. CONCLUSION: We propose a palliative treatment with cholangioscopic Argon plasma coagulation of the biliary lesions that can be performed during a surgical exploration or a percutaneous management.

Neoadjuvant therapy and mini-invasive total mesorectal excision for rectal cancer: feasibility and outcome analysis from a single institution prospectively collected data base.

AIM AND BACKGROUND: Neoadjuvant treatment for rectal adenocarcinoma improves local control and represents the standard for locally advanced disease. Laparoscopic and robotic total mesorectal excision has been increasingly adopted. It provides magnified visualization of the pelvic cavity, thereby facilitating the mesorectal dissection. METHODS: Consecutive patients with locally advanced/ultralow rectal adenocarcinoma received neoadjuvant treatment and mini-invasive total mesorectal excision at our center. We retrospectively reviewed the clinical records by using a prospectively collected data base and focusing on feasibility, tumor response and treatment outcomes. RESULTS: In a 13-year period, 117 rectal adenocarcinoma patients (80 males and 37 females) received neoadjuvant treatment and mini-invasive total mesorectal excision. Median age at diagnosis was 67 years; pre-treatment stage was I in 10 (9%); IIA in 58 (50%); IIC in 5 (4%); IIIA in 10 (9%); IIIB in 31 (26%) and IV in 3 (2%) patients. All patients received external beam radiation therapy, 79 (67%) combined with fluorouracil-based chemotherapy. One-hundred and three patients underwent laparoscopic surgery and 14 robotic surgery. Overall, 90 patients (77%) had anterior resection and 27 (23%) had abdominoperineal resection. Down-staging was obtained in 70 patients (66%). No major intraoperative nor delayed surgical complications were observed. At a median follow up of 52 months, 8 patients (7%) had a local relapse, 7 of them along with distant relapse, and 16 (14%) had distant relapse. The 5-year relapse-free survival was 76.5%. CONCLUSIONS: Our data suggest that in a community hospital mini-invasive surgery after neoadjuvant treatment is feasible in real clinical practice and achieves consistent results in term of disease control rate.

A Single Centre Retrospective Evaluation of Laparoscopic Rectal Resection with TME for Rectal Cancer: 5-Year Cancer-Specific Survival.

Laparoscopic colon resection has established its role as a minimally invasive approach to colorectal diseases. Better long-term survival rate is suggested to be achievable with this approach in colon cancer patients, whereas some doubts were raised about its safety in rectal cancer. Here we report on our single centre experience of rectal laparoscopic resections for cancer focusing on short- and long-term oncological outcomes. In the last 13 years, 248 patients underwent minimally invasive approach for rectal cancer at our centre. We focused on 99 stage I, II, and III patients with a minimum follow-up period of 5 years. Of them 43 had a middle and 56 lower rectal tumor. Laparoscopic anterior rectal resection was performed in 71 patients whereas laparoscopic abdomino-perineal resection in 28. The overall mortality rate was 1%; the overall morbidity rate was 29%. The 5-year disease-free survival rate was 69.7%, The 5-year overall survival rate was 78.8%.
