Abstract
Introduction Lack of documented tattooing of colorectal neoplasms at index colonoscopy results in high repeat preoperative colonoscopy rates. We developed national consensus recommendations for endoscopic localization and piloted an electronic synoptic reporting template. We report on the implementation and perceptions of using synoptic reporting to enhance colorectal lesion marking in a central Canadian healthcare system. Methods We implemented the template within our endoscopy reporting system and ran an infographic education campaign. We then conducted a follow-up email-based interview with all regional endoscopists. Thematic analysis and a mixed-methods triangulation approach were employed to synthesize qualitative and quantitative data. Results The interview was completed by 28/52 endoscopists (54%). Most (60.7%; n = 17) completed >100 colonoscopies and 71.4% (n = 20) identified six to 20 neoplasms requiring tattooing since introduction. A total of 50% (n = 14) used the template. Those not using it were unaware of it (42.9%; n = 12), or preferred using narrative text (17.9%; n = 5). Users reported modest mean functionality scores (intuitiveness: 3.56/5; efficiency: 3.7/5) and high impact scores (credible: 4.22/5; informative: 4.21/5). However, the perception of the synoptic template's ability to reduce the repeat preoperative colonoscopy rate was more circumspect (3.76/5). Conclusions Endoscopists believed the synoptic template was a functional, impactful tool that would improve communication and help to decrease the repeat preoperative colonoscopy rate. However, synoptic template uptake was limited by provider awareness, therefore more educational efforts are needed to increase uptake.

Preoperative tumor marking with indocyanine green (ICG) prior to minimally invasive colorectal cancer: a systematic review of current literature. Front Surg 2023; 10:1258343. [PMID: 37638121 PMCID: PMC10453801 DOI: 10.3389/fsurg.2023.1258343] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Accepted: 08/03/2023] [Indexed: 08/29/2023] Open
Abstract
Aim To describe the currently available evidence regarding the efficacy and safety of preoperative tumor marking using indocyanine green (ICG) prior to laparoscopic or robotic colorectal resections. Methods A systematic search for relevant studies was conducted using the following databases: Embase (OVID), MEDLINE® (OVID), APA PsycInfo (OVID), Global Health (OVID) and HMIC Health Management Information Consortium (OVID) through June 2022 reported according to PRISMA 2020 guidelines. Primary outcome was the detection rate of the tumor sites preoperatively marked with ICG. Secondary outcomes were timing of ICG injection in days prior to the operation and technique-related complications. Results Eight single center studies, published between 2008 and 2022, were identified yielding a total of 1,061 patients, of whom 696 were preoperatively tattooed with ICG. Injection dosage of diluted ICG ranged from 0.1-1.5 ml. Four studies used the saline test injection method prior to ICG injection. When the marking was placed within one week, the visualization rate was 650/668 (97%), whereas when it was longer than one week, the detection rate was 8/56 (14%). No severe complications were reported. Conclusion Preoperative tumor marking using ICG prior to minimally invasive colorectal resections is safe and effective, allowing intraoperative tumor site location when performed up to a week prior to surgery without disturbing the surgical view in potential mild complications.

Abstract
PURPOSE Identifying tumor location is important in colorectal tumor resection. Preoperative endoscopic India ink marking is a widespread practice, but local injection of ink is an unstable procedure. Although it is often invisible, the ink may be sprayed into the peritoneal cavity and contaminate the surgical field. At our hospital, we introduced fluorescent clip marking (FCM) using the Zeoclip FS®, an endoscopic clip developed using near-infrared fluorescent resin. We tested the usefulness of FCM by retrospectively comparing cases in which FCM was used with cases in which conventional ink marking was used. METHODS We enrolled 305 patients with colorectal tumors who underwent colorectal surgery after preoperative marking from January 2017 to April 2022. We classified the patients into the FCM group (86 patients) and the India ink tattoo group (219 patients). Endoscopic marking was completed in the FCM group by the day before surgery, and fluorescence was evaluated during surgery with a fluorescent laparoscopic system. Patient backgrounds, marking visibility, adverse effects, and early postoperative results were retrospectively compared between groups. RESULTS Marking was visually confirmed in 80 patients in the FCM group (93.02%) and in 166 patients in the India ink tattoo group (75.80%) (p = 0.0006). In the group with India ink tattoos, contamination of the surgical field was observed in seven cases (3.20%). No adverse events were observed in the FCM group. CONCLUSION In colorectal surgery, FCM provides better visibility than the conventional India ink tattooing method and is a simple and safe marking method.

Abstract
PURPOSE The effect of preoperative endoscopic tattooing (ET) on accurate colorectal cancer localization and resection has been well established. However, its effect on lymph node (LN) retrieval remains unclear. The purpose of this study was to systematically compare LN retrieval between patients with colorectal cancer who underwent preoperative ET and those who did not. METHODS A systematic search for relevant studies was conducted using the following databases: PubMed, Embase, and Web of Science. Studies that compared LN retrieval in patients with colorectal cancer with and without preoperative ET were included. Weighted pooled odds ratio (OR) and mean difference (MD) with the corresponding 95% confidence intervals (CIs) for all outcomes using the random-effects model were calculated. RESULTS 10 studies, including 2231 patients with colorectal cancer were included. Six studies reported total LN yield and showed significantly higher LN yield in the tattooed group (MD:2.61; 95% CI:1.01-4.21, P=0.001). Seven studies reported the number of patients with adequate LN retrieval and showed a significantly higher number of patients with adequate LN retrieval in the tattooed group (OR:1.89, 95% CI:1.08-3.32, P=0.03). However, subgroup analysis revealed that both outcomes were only statistically significant in patients with rectal cancer, and not in patients with colon cancer. CONCLUSIONS Our results suggest that preoperative ET is associated with increased LN retrieval in patients with rectal cancer, but not in colon cancer. Further large-scale randomized control trials are necessary to validate our findings.

Abstract
BACKGROUND Laparoscopic colorectal surgery has been proved to have similar oncological outcomes with open surgery. Due to the lack of tactile perception, surgeons may have misjudgments in laparoscopic colorectal surgery. Therefore, the accurate localization of a tumor before surgery is important, especially in the early stages of cancer. Autologous blood was thought a feasible and safe tattooing agent for preoperative endoscopic localization but its benefits remain controversial. We therefore proposed this randomized trial to the accuracy and safety of autogenous blood localization in small, serosa-negative lesion which will be resected by laparoscopic colectomy. METHODS The current study is a single-center, open-label, non-inferiority, randomized controlled trial. Eligible participants would be aged 18-80 years and diagnosed with large lateral spreading tumors that could not be treated endoscopically, malignant polyps treated endoscopically that required additional colorectal resection, and serosa-negative malignant colorectal tumors (≤ cT3). A total of 220 patients would be randomly assigned (1:1) to autologous blood group or intraoperative colonoscopy group. The primary outcome is the localization accuracy. The secondary endpoint is adverse events related to endoscopic tattooing. DISCUSSION This trial will investigate whether autologous blood marker achieves similar localization accuracy and safety in laparoscopic colorectal surgery compared to intraoperative colonoscopy. If our research hypothesis is statistically proved, the rational introduction of autologous blood tattooing in preoperative colonoscopy can help improve identification of the location of tumors for laparoscopic colorectal cancer surgery, performing an optimal resection, and minimizing unnecessary resections of normal tissues, thereby improving the patient's quality of life. Our research data will also provide high quality clinical evidence and data support for the conduction of multicenter phase III clinical trials. TRIAL REGISTRATION This study is registered with ClinicalTrials.gov, NCT05597384. Registered 28 October 2022.

Abstract
Endoscopic tattooing with India ink is a popular method for identifying colonic lesions during minimally invasive surgery because it is highly challenging to localize lesions during laparoscopy. However, there is a perceived unmet need for the injection of India ink and carbon particle suspension due to various complications and inconstant durability during the perioperative period. In this study, carbon black-containing self-healing adhesive alginate/polyvinyl alcohol composite hydrogels were synthesized as endoscopic tattooing inks. Alginate (Alg) conjugated with phenylboronic acid (PBA) groups in the backbone was crosslinked with polyvinyl alcohol (PVA) because of the dynamic bonds between the phenylboronic acid in alginate and the cis-diol groups of PVA. The carbon black-incorporated Alg-PBA/PVA hydrogels exhibited self-healing and re-shapable properties, indicating that improved intraoperative localization could be achieved. In addition, the adhesive tattooing hydrogels were stably immobilized on the target regions in the intraperitoneal spaces. These carbon black-containing self-healing adhesive hydrogels are expected to be useful in various surgical procedures, including endoscopic tattooing.

Abstract
INTRODUCTION Precise geographical localisation of colonic neoplasia is a prerequisite for proper laparoscopic oncological resection. Preoperative endoscopic peri-tumoural tattoo practice is routinely recommended but seldom scrutinised. METHODS A retrospective review of recent consecutive patients with preoperative endoscopic lesional tattoo who underwent laparoscopic colonic resection as identified from our prospectively maintained cancer database with supplementary clinical chart and radiological, histological, endoscopic and theatre database/logbook interrogation. RESULTS Some 210 patients with 'tattooed' colonic neoplasia were identified, of whom 169 underwent laparoscopic surgery (mean age 68 years, median BMI 27.8kg/m2, male-to-female ratio 95:74). The majority of tumours were malignant (149; 88%), symptomatic (133; 79%) and proximal to the splenic flexure (92; 54%). Inaccurate colonoscopist localisation judgement occurred in 12% of cases, 60% of which were corrected by preoperative staging computed tomography scan. A useful lesional tattoo was absent in 11/169 cases (6.5%) being specifically stated as present in 104 operation notes (61%) and absent in 10 (5.9%). Tumours missing overt peritumoral tattoos intraoperatively were more likely to be smaller, earlier stage and injected longer preoperatively (p=0.006), although half had histological ink staining. Eight lesions missing tattoos were radiologically occult. Four (44%) of these patients had on-table colonoscopy, and five (55%) needed laparotomy (conversion rate 55% vs 23% overall, p<0.005) with one needing a second operation to resect the initially missed target lesion. Mean (range) operative duration and postoperative length of stay of those missing tattoos compared with those with tattoos was 200 (78-300) versus 188 (50-597) min and 15.5 (4-22) versus 12(4-70) days (p>0.05). CONCLUSIONS Tattoo in advance of attempting laparoscopic resection is vital for precision cancer surgery especially for radiologically unseen tumours to avoid adverse clinical consequence.

Abstract
INTRODUCTION Preoperative endoscopic tattooing is an effective tool for intraoperative tumor localization in colon cancer. Endoscopic tattooing in rectal cancer may have unidentified benefits on lymph node yield, making it easier for pathologists to identify nodes during histopathologic assessment. There remains concern that tattoo ink may alter anatomical planes, increasing surgical difficulty. METHODS Retrospective chart reviews from 2016 to 2021 of n = 170 patients presenting with rectal cancer were divided into two groups: with (n = 79) and without (n = 91) endoscopic tattoos. Demographics, operative details, tumor characteristics, prior chemoradiation, and pathologic details were collected. Primary outcome was total lymph node yield. Secondary outcomes were rates of adequate (> 12) nodes, margin status, and operative variables including operative time. RESULTS No differences between pathologic stage, tumor height, high inferior mesenteric artery ligation, operative times, conversion rate, or surgical approach (open versus minimally invasive) were noted between groups. Receipt of neoadjuvant chemoradiation was less frequent in the endoscopic tattooing group (53.2% versus 76.9%, P ≤ 0.001). Total node number and rate of adequate lymph node yield were higher with endoscopic tattooing (20.5 ± 7.6 versus 16.8 ± 6.6 lymph nodes and 100.0% versus 83.5% adequate lymph node harvest, both P ≤ 0.001). Rates of positive circumferential and distal margins and complete total mesorectal excision were also similar. Regression analysis identified endoscopic tattooing (Incidence Risk Ratio 1.17, 95% confidence interval 1.04-1.31) and operative time more than 300 min (Incidence Risk Ratio 0.88, 95% confidence interval 0.77-0.99) had significant effects on lymph node harvest. Removal of patients with inadequate lymph node yield resulted in similar rates of total and positive lymph nodes. CONCLUSIONS Endoscopic rectal tattooing is associated with increased lymph node yield (including after neoadjuvant chemoradiotherapy) without sacrificing oncologic or perioperative outcomes, although this effect is inconsistent when only considering patients with an adequate lymph node yield.

Abstract
This prospective case-series study aimed to assess the usefulness of preoperative colonoscopic marking of colorectal tumors using Indocyanine Green (ICG) fluorescence in patients that underwent robotic surgical colorectal resections. Consecutive patients that were eligible for colorectal resection with intent to cure in a single hospital (Athens Medical Center), from February 2022 to June 2022, were included. ICG solution was injected into the submucosal layer at 2 opposite sites (180 degrees apart) distal to the tumor, without submucosal elevation. Identification of the tumor marking was then performed after switching to near-infrared (NIR) fluorescence mode. During the robotic procedure, qualitative evaluation of fluorescence was performed by the surgical team (primary surgeon, first assistant, second assistant, research fellow). All 10 patients underwent robotic surgical approach and operations included right-sided colectomy (n = 1), left-sided colectomy (n = 6) and low anterior resection (n = 3). Visualisation of this dye with near-infrared light was very clear with bright intensity in all patients when the marking was performed one day prior of surgery. Preoperative tumor marking with ICG was identified intraoperatively in all cases and the techinque was easily reproducible.

Abstract
PURPOSE Endoscopic tattooing in rectal cancer is infrequently utilized for fear of tattoo ink obscuring anatomical planes, increasing the difficulty of surgical excision. Colon cancer tattooing has demonstrated increased lymph node yields and increased accuracy in establishing adequate margins. Rectal cancer tattooing may be especially helpful after neoadjuvant chemoradiation, where complete clinical responses could limit lesion identification and lymph node yields are typically less robust. We seek to review and identify the effects of tattooing in rectal cancer. METHODS A systematic literature search was performed in PubMed, Embase, and SCOPUS. Studies on endoscopic tattooing with cohorts consisting of at least ≥ 25% of rectal cancer patients were selected. Studies focusing solely on rectal cancer were also reviewed separately. RESULTS Of 416 studies identified, 10 studies encompassing 2460 patients were evaluated. Seven studies evaluated lymph node yields; five reported beneficial effects of endoscopic tattooing, while two reported no significant difference. Among four studies reporting lesion localization, successful localization rates were between 63 and 100%. Rates of intraoperative endoscopy performed to reevaluate lesion location ranged from 5.7 to 20%. The distal margin was evaluated in two studies, which reported more accurate placement of the distal resection margin after tattooing. When complications of tattooing were documented (7 studies with 889 patients), only five direct complications of endoscopic tattooing were observed (0.6%). CONCLUSIONS Although the data is heterogenous, it suggests that endoscopic tattooing in rectal cancer may improve lymph node yields and assist in determining accurate distal margins without high rates of complication. Further research must be completed before practice management guidelines can change. TRIAL REGISTRATION No. CRD42021271784.

Abstract
BACKGROUND Repeat colonoscopy may be required for tumour localisation. The aim of the study is to explore the clinical settings it was used and benchmark the quality of initial colonoscopy against standardized guidelines for tumour localisation, tattooing and colonoscopy reporting amongst clinicians. METHODS A retrospective study from 2016 to 2021 has been performed on patients who underwent elective colorectal cancer resections at the Northern Hospital. Patient demographics, colonoscopic and operative details were retrieved from the Bi-National Colorectal Cancer Audit (BCCA) Registry database and hospital medical records. PRIMARY OUTCOMES changes in operative approach and delays to operation. SECONDARY OUTCOMES reasons for a repeat colonoscopy and complications from repeat colonoscopy. RESULTS A total of 339 patients were included in this study. 94 (28.6%) underwent a repeat colonoscopy. Re-scoping rate was 29.6% for surgeons, and 26.2% for non-operating endoscopists. Surgeons had a 5.9% localisation error rate, and non-operating endoscopist 6.95% (p = 0.673). Surgeons did not have a lower rate of repeat colonoscopy (p = 0.462). Repeat endoscopy was associated with a longer time to definitive operation (p < 0.001). No complications were associated with a repeat colonoscopy. CONCLUSION There was no difference in localisation error rates or repeat colonoscopy amongst surgeons (29.6%) and non-operating endoscopists (26.2%) (p = 0.462). This could be explained by the standardized endoscopy training in Australia governed by a common training board. Lack of tattooing at index colonoscopy and inadequate documentation often led to a repeat endoscopy, which was associated with a longer time to definitive operation. Standardized guidelines in tattooing of lesions and colonoscopy reporting should be implemented.

Abstract
Laparoscopic surgery has many advantages over open surgery. At the same time, it is not without its risks. In this review, we discuss steps that could enhance the safety of laparoscopic surgery. Some of the important safety considerations are ruling out pregnancy in women of the childbearing age group; advanced discussion with the patient regarding unexpected intraoperative situations, and ensuring appropriate equipment is available. Important perioperative safety considerations include thromboprophylaxis; antibiotic prophylaxis; patient allergies; proper positioning of the patient, stack, and monitor(s); patient appropriate pneumoperitoneum; ergonomic port placement; use of lowest possible intra-abdominal pressure; use of additional five-millimetre (mm) ports as needed; safe use of energy devices and laparoscopic staplers; low threshold for a second opinion; backing out if unsafe to proceed; avoiding hand-over in the middle of the procedure; ensuring all planned procedures have been performed; inclusion of laparoscopic retrieval bags and specimens in the operating count; avoiding 10-15 mm ports for placement of drains; appropriate port closures; and use of long-acting local anaesthetic agents for analgesia. Important postoperative considerations include adequate analgesia; early ambulation; careful attention to early warning scores; and appropriate discharge advice.

Abstract
BACKGROUND Laparoscopic localization of gastrointestinal tumors has long been an important objective. This study aimed to evaluate the clinical application of a magnetic tracer technique during laparoscopic-assisted surgery. METHODS Fifty-seven patients with gastrointestinal tumors, who voluntarily underwent endoscopic marking between May 2019 and May 2020, were enrolled. A magnetic ring was clamped onto tissues adjacent to the lesion and released during preoperative endoscopy. Then, another magnet ring or laparoscopic instrument was delivered to the wall of the digestive tract contralateral to the lesion and attracted, thus achieving accurate intraoperative localization. Observational evaluation included data regarding preoperative marking, intraoperative localization, operation, and safety. RESULTS Fifty-six of the 57 (98.2%) patients with gastric tumors (n = 35), duodenal tumors (n = 1), and colorectal tumors (n = 20), successfully underwent marking, localization, and resection. The mean margins of proximal and distal resection of colorectal tumors were 106 and 78 mm, respectively. The mean (± SD) duration of endoscopic marking and laparoscopic localization for gastric/duodenal and colorectal tumors were 5.3 ± 0.3, 1.0 ± 0.1, 5.5 ± 0.4, and 1.0 ± 0.1 min, respectively. No complications occurred in 56 of the 57 patients. CONCLUSIONS The magnetic tracer technique demonstrated promising potential as a localization method for gastrointestinal tumors, with superior safety, effectiveness, rapidity, and convenience.

Abstract
BACKGROUND Colorectal cancer is the fourth most diagnosed malignancy worldwide and surgery is one of the cornerstones of the treatment strategy. Near-infrared (NIR) fluorescence imaging is a new and upcoming technique, which uses an NIR fluorescent agent combined with a specialised camera that can detect light in the NIR range. It aims for more precise surgery with improved oncological outcomes and a reduction in complications by improving discrimination between different structures. METHODS A systematic search was conducted in the Embase, Medline and Cochrane databases with search terms corresponding to 'fluorescence-guided surgery', 'colorectal surgery', and 'colorectal cancer' to identify all relevant trials. RESULTS The following clinical applications of fluorescence guided surgery for colorectal cancer were identified and discussed: (1) tumour imaging, (2) sentinel lymph node imaging, (3) imaging of distant metastases, (4) imaging of vital structures, (5) imaging of perfusion. Both experimental and FDA/EMA approved fluorescent agents are debated. Furthermore, promising future modalities are discussed. CONCLUSION Fluorescence-guided surgery for colorectal cancer is a rapidly evolving field. The first studies show additional value of this technique regarding change in surgical management. Future trials should focus on patient related outcomes such as complication rates, disease free survival, and overall survival.

Abstract
Background: Endoscopic tattooing of colorectal tumors enables tumor localization and determination of appropriate surgical margins. It becomes very difficult to detect the distal surgical margins (DSMs) of rectal tumors in patients who obtain clinical complete response (cCR) after neoadjuvant therapy. In this study, our aim is to examine the benefits of endoscopic tattooing of the tumor before neoadjuvant therapy in patients with locally advanced rectal cancer in accurate localization of the previous tumor and in providing appropriate DSMs in cases with cCR. Patients and Methods: The patients who were diagnosed with locally advanced rectal cancer, received neoadjuvant therapy and subsequently achieved cCR, and underwent surgery between January 2015 and October 2020 were included in the study. The patients were divided into two groups according to whether they were endoscopically tattooed before neoadjuvant chemoradiotherapy. Results: A total of 49 cases were included in the study. Significantly better DSMs were observed especially in female gender in the tattooed group. DSMs were found to be closer to the resection margins in the nontattooed group. It was found that endoscopic tattooing had a significant effect on the DSM in the regression analysis (P = .06, R2 = 0.47). It was determined that laparoscopy or open surgery alone did not differ in terms of DSMs but open surgery together with tattooing was found to be strongly effective in providing larger DSMs. Conclusion: In locally advanced rectal cancer, endoscopic tattooing of the distal margin of the tumor before neoadjuvant therapy is a reliable and effective method for obtaining a safe DSM and not leaving the residual tumor at the lower end of anastomosis, especially in cases of cCR.

Abstract
Colorectal cancers comprise a large percentage of tumors worldwide, and transverse colon cancer (TCC) is defined as tumors located between hepatic and splenic flexures. Due to the anatomy and embryology complexity, and lack of large randomized controlled trials, it is a challenge to standardize TCC surgery. In this study, the current situation of transverse/extended colectomy, robotic/ laparoscopic/open surgery and complete mesocolic excision (CME) concept in TCC operations is discussed and a heatmap is conducted to show the evidence level and gap. In summary, transverse colectomy challenges the dogma of traditional extended colectomy, with similar oncological and prognostic outcomes. Compared with conventional open resection, laparoscopic and robotic surgery plays a more important role in both transverse colectomy and extended colectomy. The CME concept may contribute to the radical resection of TCC and adequate harvested lymph nodes. According to published studies, laparoscopic or robotic transverse colectomy based on the CME concept was the appropriate surgical procedure for TCC patients.

Abstract
Recently, endoscopic screening systems have enabled the diagnosis of gastric cancer in the early stages. Early gastric cancer (EGC) is typically characterized by a shallow invasion depth and small size, which can hinder localization of EGC tumors during laparoscopic surgery. Here, we review nine recently reported tumor localization methods for the laparoscopic resection of EGCs. Preoperative dye or blood tattooing has the disadvantage of spreading. Preoperative 3-dimensional computed tomography reconstruction is not performed in real time during laparoscopic gastrectomy. Thus, they are considered to have a low accuracy. Intraoperative portable abdominal radiography and intraoperative laparoscopic ultrasonography methods can provide real-time feedback, but these methods require expertise, and it can be difficult to define the clips in some gastric regions. Despite a few limitations, intraoperative gastrofibroscopy provides real-time feedback with high accuracy. The detection system using an endoscopic magnetic marking clip, fluorescent clip, and radio-frequency identification detection system clip is considered highly accurate and provides real-time feedback; we expect a commercial version of this setup to be available in the near future. However, there is not yet an easy method for accurate real-time detection. We hope that improved devices will soon be developed and used in clinical settings.

Abstract
BACKGROUND Appropriate tattooing of suspicious lesions during colonoscopy is critical for surgical planning. However, variability exists in tattoo placement, technique, and reporting. Our aim is to determine the rates and predictors of tattoo placement, tattoo location in relation to the lesion, and localization accuracy during lower endoscopy for individuals undergoing elective colorectal resections. METHODS We performed a retrospective chart review on all patients undergoing elective colorectal resections for benign and malignant neoplasms between 2007 and 2017 at a high volume Canadian tertiary centre. Patient demographics, endoscopic, and tumour-related characteristics were collected. Multivariable logistic regression analysis was used to identify predictors of tattoo localization. RESULTS Of the 1062 patients identified, laparoscopic resection occurred in 59% of patients. 57% of patients underwent tattooing for tumour localization at index endoscopy. Tattoos were placed distal (27%), both proximal and distal (4%), and just proximal (2%) to the lesion. However, in the majority of cases the tattoo location was not documented (67%). On multivariate analysis, patients who had lesions located in the transverse colon (OR: 1.93, 95% CI 1.04-3.59), had surgery performed after 2010 (2011-2014: OR: 1.88, 95% CI 1.31-2.68; 2015-2017: OR: 2.87, 95% CI 1.93-4.26), underwent laparoscopic resections (OR: 1.69, 95% CI 1.22-2.33), and had their index endoscopy performed in an urban setting (OR: 5.92, 95% CI 3.23-10.87), were at higher odds of having a tattoo placed at index endoscopy. CONCLUSION Endoscopic tattoo placement and location in relation to the lesion varies widely, with reports containing suboptimal documentation. Lesion location and laparoscopic procedures were significant predictors of tattoo placement. This study highlights the need for standardized tattooing practices and reporting amongst endoscopists. One of the focus of quality improvement efforts should be educational initiatives for rural endoscopists.

Abstract
BACKGROUND Different markers have been used preoperatively to mark colonic lesions, especially India ink. In recent years, another kind of marker has been developed: sterile carbon particle suspension (SCPS). No comparison between these two markers has yet been made. The aim of the present study was to compare the pyrogenic, inflammatory and intraperitoneal effect of these two markers. METHODS From September 2015 to December 2018, adult patients who were candidates for elective laparoscopic colon resection were randomized to the SCPS or conventional India ink injection group using computer-based randomization. The primary endpoint of the study was the presence of intraoperative adhesions related to the endoscopic tattoo. Secondary endpoints were differences in white blood cell, C-reactive protein, and fibrinogen levels as well as, abdominal pain and body temperature at baseline (before endoscopic tattooing) and 6 and 24 h after colonoscopy. Finally, the visibility of the tattoo during the minimally invasive intervention was assessed. RESULTS Ninety-four patients were included in the study, 47 for each arm. There were 45/94 females (47.9%) and 49/94 males (52.1%), with a median age of 67.85 ± 9.22 years. No differences were found between groups in WBC, fibrinogen levels, body temperature or VAS scores, but we documented significantly higher CRP values at 6 and 24 h after endoscopic tattooing with India ink injection. There were significantly fewer adhesions in the SCPS Endoscopic Marker group. All the endoscopic tattoos were clearly visible. CONCLUSIONS SCPS is an effective method for tattooing colonic lesions and has a better safety profile than traditional India ink in terms of post-procedure inflammatory response and intraoperative bowel adhesions.

Size and lipid modification determine liposomal Indocyanine green performance for tumor imaging in a model of rectal cancer. Sci Rep 2019; 9:8566. [PMID: 31189986 PMCID: PMC6561977 DOI: 10.1038/s41598-019-45038-w] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2018] [Accepted: 05/29/2019] [Indexed: 01/16/2023] Open
Abstract
Localization of rectal tumors is a challenge in minimally invasive surgery due to the lack of tactile sensation. We had developed liposomal indocyanine green (Lip-ICG) for localization of rectal tumor. In this study we evaluated the effects of liposome size and lipid PEGylation on imaging. We used an endoscopically-guided orthotopic experimental rectal cancer model in which tumor fluorescence was determined at different time points after intravenous (i.v.) administration of Lip-ICG and PEGylated liposomes (PEG-Lip-ICG). Signal intensity was measured by tumor-to-background ratio (TBR), or normalized TBR (compared to TBR of free ICG). Fluorescence microscopy of tumor tissue was performed to determine fluorescence localization within the tissue and blood vessels. Liposomes of 60 nm showed an increased TBR compared with free ICG at 12 hours after i.v. injection: normalized TBR (nTBR) = 3.11 vs. 1, respectively (p = 0.006). Larger liposomes (100 nm and 140 nm) had comparable signal to free ICG (nTBR = 0.98 ± 0.02 and 0.78 ± 0.08, respectively), even when additional time points were examined (0.5, 3 and 24 hours). PEG-Lip- ICG were more efficient than Lip-ICG (TBR = 4.2 ± 0.18 vs. 2.5 ± 0.12, p < 0.01) presumably because of reduced uptake by the reticulo-endothelial system. ICG was found outside the capillaries in tumor margins. We conclude that size and lipid modification impact imaging intensity.

Usefulness of colonic tattooing using indocyanine green in patients with colorectal tumors. World J Clin Cases 2018; 6:632-640.

Abstract
AIM To prove that tattooing using indocyanine green (ICG) is feasible in laparoscopic surgery for a colon tumor.
METHODS From January 2012 to December 2016, all patients who underwent laparoscopic colonic surgery were retrospectively screened, and 1010 patients with colorectal neoplasms were included. Their lesions were tattooed with ICG the day before the operation. The tattooed group (TG) included 114 patients, and the non-tattooed group (NTG) was selected by propensity score matching of subjects based on age, sex, tumor staging, and operation method (n = 228). In total, 342 patients were enrolled. Between the groups, the changes in [Delta (Δ), preoperative-postoperative] the hemoglobin and albumin levels, operation time, hospital stay, oral ingestion period, transfusion, and perioperative complications were compared.
RESULTS Preoperative TG had a shorter operation time (174.76 ± 51.6 min vs 192.63 ± 59.9 min, P < 0.01), hospital stay (9.55 ± 3.36 d vs 11.42 ± 8.23 d, P < 0.01), and post-operative oral ingestion period (1.58 ± 0.96 d vs 2.81 ± 1.90 d, P < 0.01). The Δ hemoglobin (0.78 ± 0.76 g/dL vs 2.2 ± 1.18 g/dL, P < 0.01) and Δ albumin (0.41 ± 0.44 g/dL vs 1.08 ± 0.39 g/dL, P < 0.01) levels were lower in the TG. On comparison of patients in the “N0” and “N1 or N2” groups, the N0 colon cancer group had a better operation time, length of hospital stay, oral ingestion period, Δ hemoglobin, and Δ albumin results than those of the N1 or N2 group. The operation methods affected the results, and laparoscopic anterior resection (LAR) showed similar results. However, for left and right hemicolectomy, both groups showed no difference in operation time or hospital stay.
CONCLUSION Preoperative tattooing with ICG is useful for laparoscopic colectomy, especially in the N0 colon cancer group and LAR.

Abstract
BACKGROUND AND AIM Preoperative endoscopic tattooing is an effective procedure to identify small intraoperative neoplasms. However, there are no defined criteria with regard to the indications for endoscopic tattooing of these lesions at the time of diagnosis. The aim of this study was to establish endoscopic criteria that allow the selection of patients who will need a tattoo during the diagnostic colonoscopy. METHODS An ambispective study of patients undergoing laparoscopy due to a colorectal neoplasia who underwent endoscopic tattooing during the period from 2007-2013 and 2016-2017. According to the endoscopic description of the neoplasms, the classification was polypoid lesions, neoplasms occupying < 50% or ≥ 50% of the intestinal lumen and stenosing neoplasias. RESULTS Tattooing of the lesion was performed in 120 patients and the same lesions were identified during surgery in 114 (95%) cases. Most of the neoplasias described as polypoids and neoplasias that occupied < 50% of the intestinal lumen were not visualized during surgery and therefore required a tattoo (33 of 42 and 18 of 26 respectively, p = 0.0001, X2). On the other hand, stenosing lesions or neoplasias occupying ≥ 50% of the intestinal lumen were mostly identified during surgery (15 of 15 and 36 of 37 respectively, p = 0.0001, X2) without the need for a tattoo. Overall, the identification of neoplasms according to established criteria was 98%. CONCLUSION These results suggest that it is possible to establish endoscopic criteria that allow a successful selective tattooing during diagnostic endoscopy.

Abstract
Preoperative endoscopic tattoo is becoming more important with the advent of minimally invasive surgery. Current practices are variable and are operator-dependent. There are no evidence-based guidelines to aid endoscopists in clinical practice. Furthermore, there are still a number of issues with endoscopic tattoo including poor intraoperative visualisation, complications from tattooing and inaccurate documentation leading to the need for intraoperative endoscopy, prolonged operative time and reoperation due to lack of oncologic resection. This review aims to collate and summarise evidence for the best practice of endoscopic tattoo for colorectal lesions in order to provide guidance for endoscopists.

Abstract
Endoscopic tattooing is a simple and effective technique for marking small lesions, so they can be localized during surgery or in later endoscopies. Various agents can be used such as India ink or a solution of purified carbon particles. The number of complications from tattooing is relatively small, but not rare. The majority of the literature on the subject refers to complications in the colon. We present a case of gastric bleeding secondary to a laceration following tattooing with purified carbon, and a literature review.

Abstract
BACKGROUND Tumor localization may pose a significant challenge during minimally invasive rectal resection. Near-infrared (NIR) imaging can penetrate biological tissue and afford tumor localization from the external surface of the rectum. Our aim was to develop an NIR-based tool for rectal tumor imaging that can be administered intravenously. METHODS We prepared indocyanine-green (ICG)-loaded liposomes by sonication. Liposomes were evaluated for their size and morphology. We then used an endoscopically induced rectal cancer in mice as a model for rectal cancer. After intravenous administration, tumors were evaluated for their fluorescence intensity. Tumor intensity was expressed in relation to the background signal, that is, tumor to background ratio (TBR). RESULTS Liposomes in various sizes could be prepared by adjusting sonication time. We selected 100-nm-sized liposomes for further experiments. Transmission electron microscopy showed spherical particles and confirmed the size measurements. The liposomes could be lyophilized and then rehydrated again before use without compromising their structure or signal. Fluorescence intensity was kept for 24 hours after solubilization. Testing the optimal time course for rectal tumor imaging revealed that early time course (up to 3 hours) yielded nonspecific imaging, whereas after long time course (24 hours), a very weak signal remained in the tissue. The optimal time window for imaging was after 12 hours from injection, with TBR = 8.1 ± 3.6 ( P = .002). Free ICG could not achieve similar results. CONCLUSIONS The liposomal ICG can be reproducibly prepared and kept in lyophilized form. Liposomal ICG could serve as a tool for intraoperative tumor localization.

Abstract
BACKGROUND Preoperative colorectal tumor localization is crucial for appropriate resection and treatment planning. As the localization accuracy of conventional colonoscopy is considered to be low, several localization techniques have been developed. We systematically reviewed the tumor localization error rates of several preoperative endoscopic techniques and synthesized information on risk factors for localization errors and procedure-related adverse events. METHODS MEDLINE, EMBASE, the Cochrane Library, and the grey literature were searched. Studies were included if they reported tumor localization errors in patients with colorectal cancer undergoing resection with curative intent. Using random-effects models, pooled incidence of tumor localization errors were derived for conventional colonoscopy and colonoscopic tattooing. Due to the lack of comparative studies, a direct comparison of the pooled estimates was performed. Procedure-related adverse events, risk factors for localization errors, and the localization outcomes of other techniques such as colonoscopic clip placement, radioguided occult colonic lesion identification, and the use of magnetic endoscope imaging were also synthesized. RESULTS A total of 38 non-randomized controlled and observational studies were included in this review (2578 patients underwent conventional colonoscopy and 643 colonoscopic tattooing). The pooled incidence of localization errors with conventional colonoscopy was 15.4 % (95 % CI 12.0-18.7), whereas that of colonoscopic tattooing was 9.5 % (95 % CI 5.7-13.3), mean difference 5.9 % (95 % CI 0.65-11.14, p = 0.03). Adverse events secondary to tattooing were infrequent, and most were cases of ink spillage. Limited information was available for other localization techniques. CONCLUSION Conventional colonoscopy has a higher incidence of localization error compared to colonoscopic tattooing for localization of colorectal cancer. Colonoscopic tattooing is safe and leads to fewer tumor localization errors. Given the widespread adoption of laparoscopic resections for colorectal cancer, routine colonoscopic tattooing should be adopted. However, studies directly comparing different localization techniques are needed.

Abstract
The use of intraoperative colonoscopy has increased alongside progress in the development of colonoscopy-associated devices and techniques, including the colonoscope itself. In the present review, we focus on four circumstances in which intraoperative colonoscopy is beneficial to colorectal surgery: (i) intraoperative determination of a tumor's location; (ii) observation of the proximal colon in cases of obstructive colorectal cancer; (iii) confirmation of the integrity of anastomosis; and (iv) novel surgical techniques that combine laparoscopic and endoscopic surgery. In light of the findings of our review, a combination of colonoscopy and surgery-especially laparoscopic surgery-is expected to facilitate the optimal handling of a variety of colorectal tumors, ranging from benign cases to advanced and obstructive cases.

Abstract
BACKGROUND The main requirements when performing laparoscopic local resection for early mucosal tumors of the stomach are a clearly defined cancer-free margin and precise tumor localization. In this study, a novel method for precise intraoperative tumor localization and appropriate resection in a porcine model is introduced: endoscopic submucosal cutting and light transmission (ESCLT). METHODS A total of 15 cases of laparoscopic local resection were performed in 6 pigs. The size of the target lesions was approximately 20 mm. The imaginary lesions were located in the high body anterior wall, posterior wall, lower body posterior wall, angle, and antrum anterior wall of the stomach. Mucosal marking around the lesions, mucosal precutting surrounding the marking, and submucosal cutting along the precutting line using white light endoscopy were sequentially performed. Next, an endoscopic light source was placed directly in front of the lesion. Exact oval-shaped submucosal cutting margins were identified via laparoscopy. Laparoscopic local resection was performed after the minimal distance from the stapler line to the submucosal cutting line was confirmed. The sizes of the mucosal marking, submucosal cutting line, and the entire resected mucosa and serosa were measured. RESULTS The procedure was completed successfully in all pigs. Local resection was completed on all of the lesions. The mean endoscopic and laparoscopic procedure times were 26.1 and 12.7 min, respectively. The mean size of the resected specimens was: (i) marking lesion, 22 × 19.5 mm; (ii) submucosal cutting line, 26.7 × 23.2 mm; (iii) entire resected mucosa, 37 × 31 mm; and (iv) entire resected serosa, 41.7 × 33.1 mm. There was no intraoperative morbidity. CONCLUSION ESCLT provides a precise and useful method of intraoperative tumor localization during laparoscopic local resection of the stomach in terms of minimizing the resection of normal stomach tissue and guaranteeing adequate mucosal safety margins.

Abstract
AIM To evaluate the impact of contrast-enhanced computed tomography colonography (CE-CTC) on laparoscopic surgery planning in patient with stenosing colorectal cancer. MATERIALS AND METHODS Sixty-nine patients with endoscopically proven colorectal cancer underwent CE-CTC, after incomplete conventional colonoscopy. Two experienced radiologists evaluated site, length, and TNM staging of colorectal cancers on three-dimensional double contrast enema-like views, 2D axial and multiplanar reconstructions. All the patients underwent colorectal resection and surgery bulletin, pathology of surgical specimens, and radiological follow-up at about 8 months were used as reference standard. RESULTS The detection rate of colorectal cancer was 100 % (75/75); CE-CTC allowed for a diagnosis of a synchronous colorectal cancer in five patients (7 %). CE-CTC correctly judged the site of the lesions in all the cases; clinically significant localization errors at conventional colonoscopy were noted in 3 out of 69 patients (4 %). Additional colonic polyps greater than 6 mm in diameter were found in 21 out of 69 patients (30 %); in two patients (3 %) the surgeon performed an enlarged colectomy to include synchronous polyps proximal to colorectal cancer. Sensitivity, specificity, PPV, NPV, and accuracy were for T1-T2 vs. T3-T4: 96 %, 71 %, 92 %, 87 %, and 91 %, respectively; for N: 94 %, 42 %, 64 %, 86 %, and 70 %; for M: 100 %, 100 %, 83 %, 100 %, and 97 %. There were no complications associated with CE-CTC. CONCLUSION Information given by CE-CTC concerning colorectal cancer location and synchronous colonic cancers and polyps changed the laparoscopic surgical strategy in almost 14 % of patients.

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
Obtaining a reliable distal margin during anterior colorectal resection can be difficult. In this study, endoscopic transmural tattoos were placed to mark the distal transection point in patients with distal colorectal neoplasms who undergo bowel resection. In the operating room, before surgery, sigmoidoscopy is performed with a 2-channel scope using CO2 insufflation. Through channel 1, a biopsy forceps, marked 5 cm from its end, is inserted to the tumor’s distal edge; in channel 2, a sclerotherapy catheter is placed. The scope is then withdrawn and forceps inserted at the same rate until the mark is seen, next, via the needle catheter, 4 tattoos are placed at that level circumferentially. After rectal mobilization, visible external tattoos guide stapler placement. If no tattoo is seen, sigmoidoscopy is done and the tattoos used to guide stapler placement. In all 27 patients, the tattoos guided stapler placement; tattoos were seen via the abdomen in 26 and the stapler placed as per tattoos in 25. In 2 patients, repeat endoscopy was done and tattoos used to guide or confirm stapler placement. The margin was ≤1 cm from target in 74% while in 22% the margin was 2 to 3.5 cm off target (mean deviation from target margin = 0.33 cm). In conclusion, this method facilitates stapler placement and provides more reliable margins.

Abstract
BACKGROUND Determining resection margins for gastric cancer, which generally is not exposed to the serosal surface of the stomach, is the most important priority during totally laparoscopic gastrectomy (TLG). This study aimed to evaluate the usefulness of intraoperative gastroscopy for direct marking of tumors during TLG for gastric cancer in the middle third of the stomach. METHODS From May 2011 through July 2012, 20 patients with a diagnosis of adenocarcinoma in the middle third of the stomach were enrolled in this case series. Preoperative gastroscopy for tumor localization was not performed for these patients. After the first portion of the duodenum was mobilized from the pancreas and clamped with a laparoscopic intestinal clamp, 2-3 ml of indigo carmine was administered through an endoscopic injector into the gastric muscle layer at the proximal margin of the tumor. RESULTS Based on intraoperative gastroscopic findings, distal subtotal gastrectomy was performed for 18 patients, with the authors deciding to perform total gastrectomy for two patients. A specimen was extracted after distal gastrectomy to confirm sufficient distance from the resection margin to the tumor before reconstruction. All the patients had tumor-free margins and required no additional resection. No morbidity related to gastroscopic procedure occurred, and the time required has been gradually decreased to about 5 min. CONCLUSIONS Intraoperative gastroscopy for tumor localization is an accurate and comfortable method for gastric cancer patients undergoing totally laparoscopic distal gastrectomy.

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
Purpose During laparoscopic partial cystectomy (LPC), lesion identification is essential to help to determine the appropriate bladder incisions required to maintain adequate resection margins. The inability to use tactile senses makes it difficult for surgeons to locate lesions during laparoscopic surgery. Endoscopic India ink marking techniques are often used in laparoscopic gastroenterological surgery. We present our experience with performing LPC with India ink during the surgical resection of various bladder lesions. Materials and Methods LPC with cystoscopic fine needle tattooing was performed on 10 patients at our institute. Tattooing was performed at 1- to 2-cm intervals approximately 1 cm away from the outer margin of the lesion with enough depth (the deep muscle layer) under cystoscopic guidance. LPC was performed by the transperitoneal approach. The clinical courses and pathologic results were analyzed. Results All LPC with cystoscopic tattooing cases were performed successfully. The mean patient age was 39.1 years. The mean operative time was 130.5 minutes, and the mean estimated blood loss was 93 ml. The mean hospital stay was 13.1 days, and the mean duration of indwelling Foley catheterization was 10.7 days. There were no significant intraoperative or postoperative complications except 1 case of delayed urinary leak and 1 case of delayed wound healing. The pathological diagnosis included 1 urachal cancer, 1 urachal remnant, 4 urachal cysts, 2 pheochromocytomas, and 2 inflammatory masses. All specimens showed adequate surgical margins. Conclusions Cystoscopic tattooing in LPC is a simple and effective technique to assist in locating pathological bladder lesions intraoperatively. This technique can help to determine appropriate resection margins during LPC without incurring additional complicated procedures.

Abstract
The management of rectal cancer has transformed over the last 3 decades and continues to evolve. Some of these changes parallel progress made with other cancers: refinement of surgical technique to improve organ preservation, selective use of neoadjuvant (and adjuvant) therapy, and emergence of criteria suggesting a role for individually tailored therapy. Other changes are driven by fairly unique issues including functional considerations, rectal anatomic features, and surgical technical issues. Further complexity is due to the variety of staging modalities (each with its own limitations), neoadjuvant treatment alternatives, and competing strategies for sequencing multimodal treatment even for nonmetastatic disease. Importantly, observations of tumor response made in the era of neoadjuvant therapy are reshaping some traditionally held concepts about tumor behavior. Frameworks for prioritizing and integrating complex data can help to formulate treatment plans for patients.

Abstract
BACKGROUND In laparoscopic-assisted colon surgery, an abdominal incision is needed to remove the specimen and perform an anastomosis. We adopted the technique of totally laparoscopic right hemicolectomy and transvaginal extraction in women who required right colon resection. METHODS Over a 2-year period, 14 women were scheduled for totally laparoscopic right hemicolectomy with intracorporeal anastomosis and transvaginal colon removal. The indications for surgery included malignant (n=9) and benign (n=5) right-side colon pathology. RESULTS The procedure was accomplished laparoscopically in all patients. In 1 patient, the transvaginal removal was not possible because of a large tumor mass. The American Society of Anesthesiology was III in 13 and II in 1 patient. The mean body mass index was 31.65. Seventy-eight percent of patients had undergone abdominal surgery previously. The mean size of the lesion was 3.75 cm (range, 1.8 to 8.0 cm) and the mean number of lymph nodes was 18.7 (range, 8 to 37). All margins in the resected specimens were macroscopically and microscopically free of any tumor. One patient needed reoperation for intra-abdominal bleeding, whereas 3 patients developed postoperative ileus. DISCUSSION Laparoscopic right hemicolectomy and transvaginal extraction is a safe and effective procedure that can be added to the armamentarium of surgeons performing laparoscopic colon surgery. This technique may provide both an attractive way to reduce abdominal wall morbidity and a bridge to pure natural orifice transluminal endoscopic surgery for colon surgery.

Abstract
BACKGROUND Knowledge of the intraoperative location of lesions is a prerequisite for deciding the proper extent of gastric resection or the choice of anastomosis technique during totally laparoscopic distal gastrectomy (TLDG) for early gastric cancer (EGC). In this study we introduce a novel tumor localization method for TLDG: endoscopic blood tattooing. METHODS Twenty-three consecutive patients scheduled for TLDG for EGC were enrolled in this prospective study. The day before surgery, 2-3 ml of autologous blood was injected into the gastric muscle layer at 3-4 cm proximal to the lesion during endoscopy. RESULTS The study subjects consisted of 15 males and 8 females with a mean age of 61 ± 10.4 years. During surgery, the endoscopic blood tattooed sites were successfully identified in all 23 patients. No complications associated with the procedure occurred, and no patient had microscopic residual tumor cells at the proximal resection margin, with a mean proximal margin length of 3.3 ± 2.7 cm. Eighteen patients underwent TLDG with Billroth II anastomosis, four patients with Roux-en-Y gastrojejunostomy, and one patient with laparoscopic total gastrectomy. At final pathologic examinations, 20 patients were of stage IA and 3 were of stage IB according to the UICC TNM classification (6th ed.). CONCLUSIONS Endoscopic blood tattooing provides a simple and useful means of localizing lesions during TLDG for EGC. Although the superiority of this technique over other localization methods needs to be evaluated further, the authors recommend endoscopic blood tattooing as an alternative to other intraoperative localization methods for laparoscopic surgery for EGC.

Abstract
Endoscopic tattooing is one of the most useful tools for the localization of small colorectal lesions especially in the laparoscopic setting. This is a minimally invasive endoscopic procedure without risk of major complications. However, many studies have revealed complications resulting from this procedure. In this article, several topics are reviewed including the accuracy, substance preparation, injected techniques and complications related to this procedure.

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 Colonoscopy findings compared with findings at time of surgery have a discrepancy rate of 3-21%. The objective of our study was to investigate this discrepancy and provide potential resolutions. METHODS In this retrospective study, we identified 400 patients who underwent colonoscopy followed by colon resection at our community hospitals in 1999-2006. Discrepancies between colonoscopy and intraoperative findings were noted. Each discrepancy was classified as major if the surgical procedure had to be altered, the lesion was missed, an unnecessary segment was removed, or the incision was extended. A discrepancy was classified as minor if there was no alteration in planned surgery. RESULTS Of the 400 cases, 160 (40%) were located in the right colon, 13 (3%) were in the transverse colon, 185 (46%) were in the left colon, and 42 (11%) were in the rectum. A total of 48 (12%) discrepancies between colonoscopy and intraoperative findings were identified: 26 (54%) were major and 22 (46%) were minor. Thirteen (27%) were in the proximal colon (3 major and 10 minor discrepancies), 3 (6.3%) were in the transverse colon (all major), 22 (46%) were in the distal colon (17 major and 5 minor), and 10 (21%) were in the rectum (3 major, 7 minor). Major discrepancies were significantly higher in the left colon (17 of the 185 left-sided lesions; 9.1%) than in the right colon (3/160; 1.9%; P = 0.045). CONCLUSIONS In our study, colonoscopy has an error rate of 12% when used to localize tumors; more than half of these patients require significant unanticipated changes in their surgery. The discrepancies are significantly higher in left side of colon.
