A novel endoscopic fluorescent clip visible with near-infrared imaging during laparoscopic surgery in a porcine model. Surg Endosc 2014; 28:1984-90.

Abstract
BACKGROUND In gastrointestinal cancer surgery, particularly in early cancer, accurate tumor localization is important in order to determine the extent of resection. In laparoscopic surgery, because of the inability to palpate the lesion, the most prevalent method of localization is endoscopic tattooing. However, complicated maneuvering makes it difficult to control local dye spreading and dye leakage into the intraperitoneal cavity. A simpler, safe method is needed. In this study, we developed a novel method for applying fluorescence-coated endoscopic clips to visualize locations inside the colon during laparoscopic surgery. We tested the procedure in an in vivo porcine model and with ex vivo human colon tissues. METHODS Bovine serum albumin was conjugated to indocyanine green or the succinimidyl ester CF™ 790 to form a pasty mixture, which was used to coat the front ends of endoscopic clips. The fluorescence-coated clips were endoscopically placed on the mucosal surface of a porcine colon. Using an Olympus near-infrared laparoscopy system, we attempted to identify the fluorescent clips from the outer, serosal side of the porcine colon during laparoscopic surgery in vivo. The clips were also evaluated using ex vivo human colon tissues. RESULTS After placing two clips on the inner, mucosal surface of the porcine colon, we used near-infrared laparoscopy to view them from the outer, serosal surface of the colon in real time during in vivo laparoscopic surgery. We also identified the fluorescence-coated clips through human colon tissues in an ex vivo study. CONCLUSIONS We developed a novel, fluorescence-coated clip that can be placed endoscopically for rapid, exact localization of colonic lesions. The clips were successfully visualized with near-infrared fluorescence imaging during laparoscopic surgery in an in vivo porcine model and in ex vivo human colon tissues.

Abstract
BACKGROUND The minilaparotomy approach is technically feasible for the resection of rectal cancer in selected patients with rapid postoperative recovery and small incision. The study aimed to compare the clinical and oncological outcomes of minilaparotomy and laparoscopic approaches in patients with rectal cancer. METHODS The 122 included patients with rectal cancer were assigned to either minilaparotomy group (n=65) or laparoscopic group (n=57) which ran from January 2005 to January 2008. Clinical characteristics, perioperative outcomes, postoperative and long-term complications, pathological results and survival rates were compared between the groups. RESULTS The demographic data of the two groups were similar. The time to normal diet (P=0.024) and the hospital stay (P=0.043) were less in the laparoscopic group than that in the minilaparotomy group. Compared with the minilaparotomy group, the mean operation time was significantly longer [low anterior resection (LAR), P=0.030; abdominoperineal resection (APR), P=0.048] and the direct costs higher for laparoscopic group (P<0.001). The morbidity and mortality were comparable between the two groups. Local recurrence was similar (5.3% laparoscopic, 1.5% minilaparotomy, P=0.520). The 5-year overall and disease-free survival rates were also similar (overall survival is 87.1% in laparoscopic group, and 82.5%in minilaparotomy group, P=0.425; disease-free survival is 74.2% in the laparoscopic group, and 71.4% in mini- laparotomy group, P=0.633). CONCLUSIONS The minilaparotomy approach was similarly safe and oncologically equivalent to laparoscopic approach for patients with rectal cancer. At the expense of a longer operative time and higher cost, laparoscopic surgery was associated with faster postoperative recovery.

Abstract
Rare adverse effects of India ink injection spillage during colonoscopy have been reported. We present a case report in which prior colonoscopic India ink tattooing was found to mimic intraperitoneal endometriosis in a 48 year-old woman undergoing laparoscopic sterilization. Multiple black lesions suspicious for endometriosis involving the anterior and posterior cul-de-sac, left ovary, and omentum were found. A pathological assessment showed peritoneal tissue with focal dark pigment associated with mild chronic inflammation and deposition of tattoo pigment; there was no evidence of endometriosis in the specimens. Surgical recognition of tattoo ink spillage in the peritoneum is very important to prevent misinterpretation of peritoneal findings.

Abstract
The value of performing comprehensive screening colonoscopy with complete colon polypectomy is widely accepted. Colon cancer is a significant cause of worldwide mortality and prospective studies have proven that colonoscopic polypectomy reduces both the incidence and mortality related to this disease. Over the past few decades the array of instruments and techniques have greatly expanded to assist with the safe endoscopic removal of colon polyps. This article will review the published literature regarding efficacy and safety of standard polypectomy techniques such as snare polypectomy, electrocautery, and endoscopic mucosal resection along with newer techniques such as endoscopic submucosal dissection and combined laparoscopic techniques.

Abstract
PURPOSE Intraoperative localization of small tumors or malignant polyps has been an important issue in laparoscopic colon surgery. We have developed a new method for preoperative endoscopic tumor marking using a ring-shaped magnetic marker. METHODS In a pilot study, 28 patients with small colonic (n = 23) or rectal tumors (n = 5) underwent endoscopic magnetic clipping prior to laparoscopic resection. A cap carrying a high-power neodymium ring magnet was mounted on the tip of a colonoscope. Near the lesion, the ring magnet was released and clipped to the colorectal wall. Standard laparoscopic instruments were used to find the magnet intraoperatively. RESULTS Endoscopic fixation of a ring magnet next to the tumor by clipping was technically feasible in all 28 patients. Intraoperative localization of the marked lesions was successful in 27 of 28 patients (96 %). All patients underwent magnet-guided radical laparoscopic resection of the tumor with an average proximal and distal resection margin of 101 and 63 mm, respectively. In one case, the magnet could not be found due to preoperative migration. Surgical complications related to magnetic clip application or intraoperative tumor localization were not observed. However, there was one case with an intraoperative perforation of the colon by the magnet, which was obviously caused by unchecked action with a laparoscopic instrument. CONCLUSIONS Preoperative endoscopic labeling of colonic lesions with on-the-scope magnetic markers is simple and safe. Intraoperative tumor localization during laparoscopic colorectal surgery can be achieved reliably without additional equipment such as ultrasound or fluoroscopy.

Abstract
The intraoperative identification of the lesions found at endoscopic examination is often difficult, especially during laparoscopic surgery. At present, the most used technique for the intraoperative detection of pathological lesions is endoscopic tattooing. The large majority of studies carried out concern colorectal lesions; however, endoscopic tattooing has also been described for esophageal, gastric, small bowel and, more recently, pancreatic lesions. In this review, the authors evaluated indications, substances used, injection techniques, accuracy, safety and, finally, the risk of complications related to this procedure.

Abstract
BACKGROUND In colorectal cancer (CRC), colonoscopic tattooing is performed to mark the tumor site before laparoscopic surgery. OBJECTIVE To determine whether colonoscopic tattooing can be used to refine staging accuracy by increasing the lymph node (LN) yield per specimen and to determine its accuracy as a sentinel LN procedure. DESIGN Retrospective, case-control study. All LNs were microscopically examined for the presence of carbon particles. SETTING A university hospital and a teaching hospital. PATIENTS A consecutive series of 95 tattooed patients who had surgery for CRC between 2005 and 2009. A series of 210 non-tattooed patients who had surgery in the same time period served as controls. MAIN OUTCOME MEASUREMENTS Total number of LNs retrieved, detection rate, and sensitivity of tattooing as a sentinel node procedure. RESULTS A higher LN yield was observed in patients with preoperative tattooing, median (interquartile range) 15 (10-20) versus 12 (9-16), (P = .014). In multivariable analysis, the presence of carbon-containing LNs was an independent predictive factor for a higher LN yield (P = .002). The detection rate was 71%, with a median of 5 carbon-containing LNs per specimen. If preoperative tattooing was used for sentinel node mapping, the overall accuracy of predicting LN status was 94%. In the 24 N1 cases, there were 4 false-negative procedures (sensitivity 83%). LIMITATIONS Retrospective series. CONCLUSION After tattooing of CRC, the LN yield was higher than in a control group, and it could be used as a sentinel node procedure with acceptable accuracy rates. Because LN yield and sentinel node mapping are associated with improved diagnostic accuracy of LN involvement, preoperative tattooing can refine staging.

Abstract
BACKGROUND Current guidelines recommend tattooing of suspicious-looking lesions at colonoscopy without a reference to the size of the polyp. However, the endoscopist has to make a judgement as to which lesion may be malignant and require future localisation based on the appearance and size of the polyp. The aim of this study was to determine the relationship between endoscopic polyp size and invasive colorectal cancer so as to inform tattooing practice for patients taking part in the national bowel cancer screening programme (BCSP). METHODS Data of BCSP patients who had undergone a polypectomy between October 2008 and October 2010 were collected from a prospectively maintained hospital endoscopic database. Histology data were obtained from electronic patient records. RESULTS A total of 165 patients had undergone 269 polypectomies. Their median age was 66 years and 66 % were men. The mean endoscopic polyp size was 10.7 mm (SD = ± 8 mm). Histologically, 81 % were neoplastic with 95 % showing low-grade and 5 % high-grade dysplasia. Eight patients were found to have invasive malignancy within their polyp. The risk of invasive malignancy within a polyp was 0.7 % (1/143) when the endoscopic polyp size was <10 mm; the risk increased to 2.4 % (2/83) when the polyp size was 10-19 mm and 13 % (5/40) when the polyp was >20 mm. This trend was statistically significant (p = 0.001). About 23 % of the patients had the site of their polyp tattooed; the mean size of the tattooed polyps was 21 mm (range = 15-50 mm). Consequently, 25 % of malignant polyps and 63 % of polyps with high-grade dysplasia were not tattooed. CONCLUSION The risk of polyp cancer among BCSP patients increases significantly when the endoscopic polyp size is ≥ 10 mm. We recommend that all polyps ≥ 10 mm be tattooed.

Abstract
BACKGROUND When transected surgical margins are involved by tumor cells during gastrectomy for gastric cancer, dissemination of tumor cells to the peritoneal cavity may be a concern. OBJECTIVES The aim of this study is to evaluate the prognostic value of tumor infiltration at the transected surgical margin during gastrectomy. METHODS A total of 1,717 patients with gastric cancer who underwent R0 gastrectomy were included. The relationship between positive margins on frozen biopsy during gastrectomy and clinicopathologic data was examined. The prognostic impact of this intraoperative event was evaluated by univariate and multivariate analysis. RESULTS The intraoperative positive resection margin occurred in 69 patients (4.01%). Tumor size >5 cm, tumor located in the upper third or whole stomach, Bormann type IV gastric cancer, and signet ring cell histology were independent factors associated with that intraoperative event. pT and pN stages were significant prognostic factors associated with locoregional and/or peritoneal recurrence and overall recurrence. Tumor infiltration at the transected margin was not an independent prognostic factor associated with any recurrence. CONCLUSIONS Microscopic tumor involvement at the margin during gastric cancer surgery does not increase locoregional and/or peritoneal recurrence or overall recurrence independently if R0 resection is achieved by re-resection of the margin.

Abstract
AIM Intra-operative localization of small cancers and polyps during laparoscopic colorectal surgery is difficult due to reduced tactile feedback. The consequences of failing to identify the lesion for resection can result in open conversion or removal of the wrong segment of bowel. METHOD Data were collected from a prospectively-kept database over a 12-month period from April 2008 to March 2009 and analysed retrospectively. Details concerning the documentation, visibility and accuracy of tattoos were recorded. RESULTS Eighty-five patients (88 lesions) underwent laparoscopic resection for a benign or malignant colorectal tumour during 1 year from April 2008. Eighty-one patients underwent endoscopic visualization of the tumour as a first or second procedure. Of these 81 patients, 83 lesions were visualized endoscopically and 54 (65.1%) were tattooed in 52 patients. In the 52 patients, 36 (69%) of the tattoos were carried out on the first endoscopy. At operation the tattoo was judged to be visible and accurate in 70%, visible but inaccurate in 7% and not visible in 15%. It was significantly easier to see the tattoo in women (19/21 women vs 21/29 men; P=0.03) but there was no relationship between tattoo visibility and BMI. An accurate tattoo did not reduce the conversion rate (P=0.71). No tattoo-related complications were encountered. CONCLUSION The practice of tattooing colorectal cancers is variable in frequency, technique and accuracy. We advocate that all colonic lesions suspicious for cancer should be tattooed during endoscopy at a defined distance below the tumour, adhering to a departmental protocol in case surgery is required.

Abstract
BACKGROUND Accurate tumor localization is essential for gastrointestinal surgery, especially in cases of early cancer. This study was designed to develop a novel fluorescent clip for rapid and exact visualization of tumor sites. METHODS A transparent polymer matrix containing highly bright fluorochromes was coated on the front end of endoscopic clips. The fluorescent clips were placed on the mucosal surface of a porcine colon and stomach, and the operator then attempted to identify the fluorescent clips from the outer serosal side of the colon and stomach. A 532-nm diode laser and filter glass were used for visualizing the fluorescence signals through the colonic tissue. A 650-nm diode laser and a digital charge-coupled device (CCD) camera equipped with a bandpass emission filter were used for the imaging of the fluorescent clips through the thick stomach tissue. RESULTS When a green light from a 532-nm diode laser (power density=0.35 mW/cm2) was applied on the serosal surface of the porcine colon, we could identify all clips that had been placed endoscopically on the mucosal surface of the inner colonic wall. By using the light from a 650-nm diode laser (power density=0.7 mW/cm2), we identified all fluorescent clips through the stomach wall in real time. Similar results were also obtained with the filtered xenon lamp. CONCLUSION An endoscopic fluorescent clip can be useful for the rapid and exact localization of tumors, and this technique can also be useful during laparoscopic surgery.

Abstract
The American Society for Gastrointestinal Endoscopy (ASGE) Technology Committee provides reviews of existing, new, or emerging endoscopic technologies that have an impact on the practice of GI endoscopy. Evidence-based methodology is used, with a MEDLINE literature search to identify pertinent clinical studies on the topic and a MAUDE (U.S. Food and Drug Administration Center for Devices and Radiological Health) database search to identify the reported complications of a given technology. Both are supplemented by accessing the "related articles" feature of PubMed and by scrutinizing pertinent references cited by the identified studies. Controlled clinical trials are emphasized, but in many cases, data from randomized, controlled trials are lacking. In such cases, large case series, preliminary clinical studies, and expert opinions are used. Technical data are gathered from traditional and Web-based publications, proprietary publications, and informal communications with pertinent vendors. Technology Status Evaluation Reports are drafted by 1 or 2 members of the ASGE Technology Committee, reviewed and edited by the committee as a whole, and approved by the Governing Board of the ASGE. When financial guidance is indicated, the most recent coding data and list prices at the time of publication are provided. For this review, the MEDLINE database was searched through January 2010 for articles related to endoscopic tattooing by using the Keywords tattooing, colonic, endoscopic, India ink, indocyanine green in different search term combinations. Technology Status Evaluation Reports are scientific reviews provided solely for educational and informational purposes. Technology Status Evaluation Reports are not rules and should not be construed as establishing a legal standard of care or as encouraging, advocating, requiring, or discouraging any particular treatment or payment for such treatment.

Abstract
AIM Accurate preoperative localization of colonic lesions is critical especially in laparoscopic colectomy where tactile localization is absent particularly in screen-detected tumours. The study aimed to evaluate the accuracy of colonoscopy and double-contrast computerized tomography (CT) scan to localize lesions treated by right hemicolectomy. METHOD A retrospective chart review was performed of patients treated by right hemicolectomy under the colorectal service between July 2003 and October 2006. Preoperative tumour location determined by CT scan and colonoscopy was compared with the intra-operative and histopathological findings. RESULTS Out of 101 patients, 73 (73%) were for adenoma or cancer, with a final diagnosis of adenocarcinoma in 59 (58%). Preoperative localization was inaccurate in 29% of lesions using both CT and colonoscopy. In the transverse colon, colonoscopy alone was only 37.5% accurate, increasing to 62.5% when information from the CT scan was added. CONCLUSION Preoperative localization of right-sided colon cancers using colonoscopy and CT scanning is unreliable in at least 29% of cases. Inaccurate localization of transverse colon tumours risks inadequate lymphadenectomy with an adverse cancer outcome. Preoperative abdominal CT scan improves accuracy but endoscopic tattoo localization should be employed routinely especially in patients undergoing laparoscopic resection.

Abstract
INTRODUCTION India ink tattooing is widely used for tumor localization; however, the tattooing procedure is not yet standardized. This study aims to evaluate the efficacy of small-dose tattooing with sterile India ink using a saline test-injection method. PATIENTS AND METHODS Between April 2009 and August 2009, 20 patients underwent colonoscopic tattooing with prepackaged sterile India ink before resection of colorectal tumor. We injected 0.5 cc of India ink at three circumferential sites at the distal tumor using a saline test-injection method. Observation and leakage of India ink were evaluated during laparoscopic surgery, and the diameter of tattooing in the specimen was assessed. RESULTS Tattoos were observed intraoperatively in 18 patients (90%). In 2 patients, tattoos were not observed on the serosal surface but were detected on the mucosal surface. Localized leakage of ink was identified during surgery in 1 patient (5%), without fever or abdominal pain. Mean tattoo diameter was 2.1 cm on the serosal surface and 2.0 cm on the mucosal surface. CONCLUSIONS Small-dose tattooing with sterile India ink using a saline test-injection method is effective for tumor localization.

Abstract
BACKGROUND Juvenile polyps have a reported incidence of up to 2% in individuals younger than of 18 years. Most polyps are small, occur in the distal colon and rectum, and present with bleeding or prolapse. Giant juvenile polyps have been rarely reported. CASE REPORTS We encountered 2 unique presentations of very large juvenile polyps in children. A 9-year-old boy presented with recurrent rectal bleeding and anemia because of a single large polyp at the hepatic flexure. A 14-year-old boy presented with abdominal pain secondary to 2 large polyps in the cecum. The polyps were seen on colonoscopy as pedunculated masses larger than 5 cm and were not subjected to biopsy. Both patients underwent laparoscopic colon mobilizations with extracorporeal segmental resection in the first patient and colotomy and polypectomy in the second. Both patients had short hospital stays and excellent outcomes. CONCLUSIONS Giant juvenile polyps are rare in children and may not be amenable to colonoscopic removal. They can be resected effectively with minimal access surgical techniques.

Abstract
OBJECTIVE Laparoscopic surgery for colorectal cancer is now widespread. Small lesions in the colon can be difficult to palpate and with lack of tactile sensation, it is essential to accurately localize them preoperatively. This is a review article on current methods of tattooing including the use of different agents and associated complications. Aim To review current techniques in preoperative tumour localization and methods used for colonic tattooing including agents used, dosage and potential complications. METHOD A literature search (Medline and Pubmed) was performed with manual cross referencing of all articles related to colonic tattooing. RESULTS Methods for localizing colonic tumours for laparoscopic resection include preoperative barium enema examination, CT colonography and intraoperative colonoscopy. The most effective method is, however, by tattooing with India ink performed endoscopically before surgery. CONCLUSION India ink is a reliable method of marking tumour location within the colon as prelude to laparoscopic resection. Surgeons must, however, be aware of potential complications associated with this technique.

Abstract
(Table is included in full-text article). Positive, certain documentation of reaching the caecum is an important aspect of colonoscopy. Traditionally recording the anatomical landmarks was commonly used to document completion; more recently photodocumentation has been utilized. A number of authors have doubted the reliability of photodocumentation, and alternative methods have been explored. The reasons for determining caecal intubation and the ways in which this can be accurately recorded are discussed.
