Abstract
BACKGROUND In rectal cancer surgery, insertion of transanal tube has been shown to have efficacy to prevent anastomotic leakage. This randomized controlled study aims to clarify the incidence of anastomotic leakage with or without transanal tube in patients with rectal cancer. METHODS Patients who underwent elective low anterior resection were randomly allocated to either have transanal tube insertion or not for five days after surgery. We examined the incidence of anastomotic leakage, postoperative 30-day morbidity and mortality. RESULTS 157 patients were randomized to the transanal tube group or the no-transanal tube group. Symptomatic anastomotic leakage occurred in six patients (7.6%) of the former group and eight patients (10.3%) in the latter group, without significant difference (p = 0.559). There was also no significant difference in morbidity between groups (p = 0.633) and no mortality was detected. CONCLUSIONS Transanal tube insertion had no significant benefit towards prevention of anastomotic leakage in rectal cancer surgery.

A systematic review and meta-analysis. Int J Colorectal Dis 2021; 36:57-66. [PMID: 32944782 DOI: 10.1007/s00384-020-03741-5] [Citation(s) in RCA: 41] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 09/08/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND Colorectal anastomoses in patients with colorectal cancer carry a high risk of leakage. Indocyanine green fluorescence angiography (ICG-FA) is a new technique that allows surgeons to assess the blood perfusion of the anastomosis during operation. This meta-analysis aimed to evaluate whether ICG-FA could prevent anastomotic leakage (AL) in colorectal surgery. METHODS Four databases (PubMed, Embase, Web of Science, and Cochrane Library) were searched to identify suitable literatures until March 2020 that compared AL rates between intraoperative use and non-use of ICG-FA in colorectal surgery for cancer. The Review Manager 5.3 software was used to perform the statistical analysis. Evaluation of articles quality and analysis for publication bias were also conducted. RESULTS Thirteen studies of 4037 patients were included in the meta-analysis. The study included 1806 patients in the ICG group and 2231 patients in the control group. The pooled incidence of AL in ICG group was 3.8% compared with 7.8% in control group. There was a significant difference in AL rate with or without use of ICG-FA (OR 0.44; 95% CI 0.33-0.59; P < 0.00001). Reoperation rates were 2.6% and 6.9% in ICG and control groups, respectively. Application of intraoperative ICG-FA was associated with a lower risk of reoperation (OR 0.39; 95% CI 0.16-0.94; P = 0.04). Overall complication rate was 15.6% in the ICG group compared with 21.2% in the control group. Overall complications were significantly reduced when using ICG-FA (OR 0.62; 95% CI 0.47-0.82; P = 0.0008). Mortality rate was not statistically different with or without the use of ICG-FA (OR 1.22; 95% CI 0.20-7.30; P = 0.83). CONCLUSION The results revealed that ICG-FA reduced risks of AL, reoperation, and overall complications for colorectal cancer patients undergoing colorectal surgery. Well-designed RCTs are needed to confirm the usefulness of intraoperative ICG-FA for preventing surgical complications like AL and reoperation.

Abstract
BACKGROUND Most preventive ileostomy following colorectal surgery requires a closure procedure. The intervals between primary surgery and ileostomy closure remain controversial. OBJECTIVE This study aimed to compare early versus late closure of preventive ileostomy following colorectal surgery. DATA SOURCE A systematic literature search was performed in conference papers, MEDLINE, EMBASE, the Cochrane Library, and the Clinicaltrials.gov database. STUDY SELECTION Randomized clinical trials published through October 2019 comparing early versus late closure of ileostomy following colorectal surgery were selected. MAIN OUTCOME MEASURES Morbidity, leak of the primary anastomosis, reoperation, surgical site infection, small-bowel obstruction/postoperative ileus, total operative time, and postoperative length of hospital stay were measured. Results were synthesized using meta-analysis and were rated as firm or weak evidence by trial sequential analysis. RESULTS A total of 6 randomized controlled trials were included. Firm evidence from trial sequential analysis demonstrated that the early closure of ileostomy after colorectal surgery reduced the incidence of small-bowel obstruction/postoperative ileus and required less total operative time, but increased the incidence of surgical site infection, compared with late closure of ileostomy; postoperative length of hospital stay tended to be longer with early versus late closure of ileostomy. Weak evidence showed that there was no difference between early and late closure in morbidity, reoperation, or leak of the primary anastomosis. LIMITATIONS The study was limited by some evidence rated as weak from trial sequential analysis, combined analysis of small-bowel obstruction and postoperative ileus, and exclusion of the influence of chemo- or radiotherapy. CONCLUSIONS In selected patients, early closure of ileostomy after colorectal surgery can be considered, with a lower incidence of postoperative small-bowel obstruction/postoperative ileus and less total operative time, but a relatively high surgical site infection rate. PROSPERO registration number: CRD42020160989.

Abstract
BACKGROUND Anastomotic leakage is a feared complication of anterior resection for rectal cancer. Among the various factors reported to be involved in the occurrence of anastomotic leakage, blood perfusion of the remnant intestine is one of the most important. Recently, the usefulness of evaluating blood perfusion using indocyanine green (ICG) has been reported. We therefore aimed to show that measuring intestinal temperature using thermography is useful for evaluating blood perfusion. The authors also investigated the relation between intestinal temperatures and the ICG fluorescence time (FT). MATERIALS AND METHODS Altogether, 45 patients who underwent laparoscopic anterior resection for rectal cancer between July 2017 and September 2018 were enrolled in this study. ICG FT and intestinal temperature were measured after the mesenteric dissection. RESULT The temperature boundary could be easily identified using thermographic images. The temperature of the residual intestinal tract was significantly higher than that of the resected intestinal tract at the planned separation line (29.9 vs. 27.3°C). In addition, there was an inverse correlation between the ICG FT and the temperature of the residual intestine. CONCLUSION Intestinal temperature measurement through thermography is a useful new tool for evaluating intestinal blood perfusion.

Abstract
Although surgeries involving anastomosis are relatively common, anastomotic leakages are potentially deadly complications of colorectal surgeries due to increased risk of morbidity and mortality. As a result of the potentially fatal effects of anastomotic leakages, a myriad of techniques and treatments have been developed to treat these unfortunate cases. In order to better understand the steps taken to treat this complication, we have created a composite review involving some of the current and best treatments for colonic anastomotic leakage that are available. The aim of this article is to present a background review of colonic anastomotic leakage, as well as current strategies to prevent and treat this condition, for a broader audience, including scientist, engineers, and especially biomedical engineers.

Abstract
Anastomotic leakage (AL) represents one of the most relevant complications of colorectal cancer surgery. The aim of this study was to evaluate the utility of intraoperative indocyanine green (ICG) fluorescence imaging in the prevention of AL during laparoscopic colorectal surgery. Methods. We retrospectively analyzed 272 patients who underwent rectal and left colon surgery, consecutively enrolled between 2015 and 2019. Due to the heterogeneity of our groups, a propensity score matching (PSM) was performed with a 1:1 PSM cohort. Results. AL occurred in 36 (13.2%) patients. One hundred seventy-seven (65%) of them underwent an intraoperatory ICG test (ICG-group), whereas 95 patients (35%) did not receive the intraoperatory ICG test (no-ICG group). AL occurred in 10.8% of ICG group patients and in 17.8% of no-ICG group patients (P = 0.07). The ICG group registered significantly less type B and type C fistulas than the no-ICG group (57.9 vs 88.2%; P = .043). After PSM, the overall AL rate was less in the ICG group than the no-ICG group (9.3% vs 16%; P = 0.058), while type B and type C fistulas occurred in 5.48% in the ICG group vs 13.70% in the no-ICG group (P = 0.09). Univariate analysis demonstrated a protective effect of intraoperative ICG imaging against AL occurrence (odds ratio (OR: 0.66)). Conclusions. Hypoperfusion is a well-recognized cause of AL. The ICG assessment of colic vascularization is a simple, inexpensive, and side effects free method, which can sensibly reduce both overall AL and type B and type C fistulas when routinely used.

Abstract
Introduction Colorectal cancer is a common type of malignant disease of the digestive tract. Anastomotic leakage (AL) still represents a serious complication in gastrointestinal surgery, associated with high morbidity and mortality. Methods We conducted a retrospective case-control study and analyzed a single surgeon’s data about 359 patients treated for colorectal cancer. Patients were divided as follows: Study Group (patients with AL - 37 patients) and Control Group (patients without AL - 322 patients). Surgical and anastomotic technique-related information was processed. Results Surgical procedures for right sided colon tumors resulted in a significantly lower rate of anastomotic leakage (P=0.0231). For left sided colectomies end to end handsewn double layer anastomosis presented decreased odds (OR=0.176). For sigmoid segmental resection end to end anastomotic techniques developed low rate of fistula formation (handsewn - OR=0.593, stapled - OR=0.685). Performing Dixon type surgical interventions, anastomotic techniques seemed without influence on anastomotic leak appearance (handsewn and stapled), although distal anastomoses were identified as significant risk factors for fistula formation (P=0.0017). In order to perform subtotal colectomy, side to side sutures (handsewn and stapled) seemed safe choices for anastomotic procedure (P=0.0073). Patient with anastomotic leakage suffered a significantly longer hospital stay (P=0.0079), presented higher rate of surgical reintervention (P=0.0001), increased mortality (P=0.0001) and elevated hospitalization costs (P=0.0079). Conclusion Postoperative complications like anastomosis leakage significantly increase hospitalization period, necessity of surgical reintervention, mortality and financial costs. In order to avoid these unpleasant events, bowel anastomoses require standardization during surgery.

Association between intraoperative application of microfibrillar collagen hemostat and anastomotic leakage after anterior resection for rectal cancer: A retrospective case-control study.

Abstract
BACKGROUND The purpose of the study was to evaluate the association between microfibrillar collagen hemostat and anastomotic leakage after anterior resection. METHOD Between March 2015 and December 2019, a total of 203 consecutive rectal cancer patients who underwent elective anterior resection were included. Patient parameters were analyzed. The relevant risk factors were identified by univariate and multivariate analysis. Propensity score matching was performed to reduce the selection bias. RESULTS In total, 26 (12.8%) of the 203 study patients developed clinical anastomotic leakage. The length of hospital stay was significantly prolonged by anastomotic leakage. In univariate analysis and multivariate analysis, male sex, low tumor location, and intraoperative application of microfibrillar collagen hemostat significantly increased the risk of anastomotic leakage. Furthermore, analysis after propensity score matching confirmed the independent role of microfibrillar collagen hemostat in anastomotic leakage. In addition, the median time of anastomotic leakage occurrence from the initial operation in patients with microfibrillar collagen hemostat was 9.00 days, which was significantly later than that in patients without microfibrillar collagen hemostat. CONCLUSION In addition to male sex and low tumor location, intraoperative application of microfibrillar collagen hemostat was demonstrated to be a significant risk factor for anastomotic leakage. This finding suggested that surgeons should be fully aware of this potential risk in anterior resection. Because of the limitation of retrospective study, however, randomized controlled trials are needed to confirm this association in the future.

Abstract
Background: To identify predictive factors for reoperation because of anastomotic leakage (AL) after colectomy. Methods: Between 2007 and 2016, all patients who developed AL following right or left colectomy in an expert center were included. Patients who were treated surgically (all including fecal diversion) were compared with those who were managed conservatively. Results: Overall, 81 (6.5%) patients developed AL, of which 32 (39%) were managed nonoperatively and 49 (61%) required reoperation. On average, AL was diagnosed on postoperative day 4 (3-8) and mortality reached 4.9% (n = 4). Reoperation included anastomosis resection in 31 (67%) patients of which 26 (100%) had right colectomy and 5 (25%) left colectomy. Reoperation for AL was associated with increased intensive care management (P = .026) and deep abdominal collection (P = .002). T stage >2 and right-sided colectomy were the only independent risk factors associated with the need for reoperation for AL. Stoma reversal was performed in 42 (98%) patients after a median of 4 months. Conclusions: AL after colectomy is more likely to require reoperation with fecal diversion after right-sided colectomy and T > 2 colorectal cancer.

Abstract
Laparoscopic surgery has become the preferred surgical approach of several colorectal conditions. However, the economic results of this are quite controversial. The degree of adoption of laparoscopic technology, as well as the aptitude of the surgeons, can have an influence not only in the clinical outcomes but also in the total procedure cost. The aim of this study was to evaluate the clinical and economic outcomes of laparoscopic colorectal surgeries, compared to open procedures in Brazil.All patients who underwent elective colorectal surgeries between January 2012 and December 2013 were eligible to the retrospective cohort. The considered follow-up period was within 30 days from the index procedure. The outcomes evaluated were the length of stay, blood transfusion, intensive care unit admission, in-hospital mortality, use of antibiotics, the development of anastomotic leakage, readmission, and the total hospital costs including re-admissions.Two hundred eighty patients, who met the eligibility criteria, were included in the analysis. Patients in the laparoscopic group had a shorter length of stay in comparison with the open group (6.02 ± 3.86 vs 9.86 ± 16.27, P < .001). There were no significant differences in other clinical outcomes between the 2 groups. The total costs were similar between the 2 groups, in the multivariate analysis (generalized linear model ratio of means 1.20, P = .074). The cost predictors were the cancer diagnosis and age.Laparoscopic colorectal surgery presents a 17% decrease in the duration of the hospital stay without increasing the total hospitalization costs. The factors associated with increased hospital costs were age and the diagnosis of cancer.

Abstract
Transanal total mesorectum excision is feasible for mid and low rectal cancer. Good quality of the mesorectum specimen is obtain after TaTME surgery. TaTME with intersphincteric resection is a feasible option for selected cases of very low rectal cancer. Surgical complication rates after intersphincteric TaTME with hand-sewn coloanal anastomosis could be higher.
Introduction Describe and demonstrate the feasibility and safety of TaTME in short term outcomes in the Instituto Nacional de Enfermedades Neoplásicas (INEN) in Peru. Materials and methods Case series with retrospective and prospective data collection of patients with middle and inferior rectal cancer who underwent TaTME between January 2015 and March 2020. Patients and tumor characteristics, operative details, postoperative complications and pathological results were analyzed. Results Nineteen patients were included. The median age was 56 years old (range 40–69). Ten were female. The median distance from the anal verge was 4 cm (range 3–6) and 17 cases were located in the inferior rectum. Eleven patients with clinical stage III. Thirteen (68.4%) patients received neoadjuvant treatment. There was no conversion to open surgery reported. Ten (52.6%) cases had intersphincteric resection and 18 (94.7%) had primary coloanal anastomosis, 13 (72.2%) of them with hand-sewn. All patients had a diversion with ileostomy. The median operative time was 330 min (range 270–480). Median postoperative hospital stay of 5 days (range 3–18). The overall rate of postoperative complication was 21.1%, two cases (10.5%) had anastomotic leakage and mortality was present in one (5.3%) patient. 94.5% had an optimal TME specimen, only one case (5.3%) had positive circumferential resection margin and positive distal margin. The median tumor size in the specimen was 4 cm (range 2–11) and nine (47.4%) patients had ypT3 on pathology. Conclusion TaTME is a safe and feasible technique with good pathological results.

Intra-operative fluorescence angiography is reproducible and reduces the rate of anastomotic leak after colorectal resection for cancer: a prospective case-matched study. Colorectal Dis 2020; 22:1263-1270. [PMID: 32306516 DOI: 10.1111/codi.15076] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2019] [Accepted: 02/03/2020] [Indexed: 02/08/2023]
Abstract
AIM Intra-operative fluorescence angiography (IOFA) with indocyanine green provides information on tissue perfusion that may help prevent an anastomotic leak (AL). The aim of this study was to assess the impact of IOFA on outcomes after left-sided colonic or low anterior resection with anastomosis for colorectal cancer. METHODS All patients with left-sided colonic or rectal cancer, operated between June 2017 and December 2018, were prospectively included. IOFA has been routinely implemented since May 2018. Reproducibility of IOFA, after a 1:1 matching for relevant clinical risk factors of AL, was studied in patients with IOFA (IOFA+) and without IOFA (IOFA-). Outcomes were compared in terms of postoperative events such as clinically relevant AL as the primary end-point. RESULTS In the IOFA+ group, changing of the initially planned colon transection due to inadequate perfusion occurred in five out of 46 patients (10.9%). Agreement between intra-operative assessment and postoperative blind review of IOFA was deemed strong (Cohen's kappa index 0.893, 95% CI 0.788-0.998, P < 0.001). Among 111 patients, 42 matched patients were included in each group. There was significantly more clinically relevant AL in the IOFA- group compared to the IOFA+ group (16.7% vs 2.4%, P = 0.026) involving significantly more anastomotic dehiscence which required re-intervention (19% vs 2.4%, P = 0.014). Additionally, more descending colon ischaemia/necrosis was observed in the IOFA- group compared with the IOFA+ group (9.5% vs 0%, P = 0.040). CONCLUSION In this prospective case-matched study, IOFA decreased the occurrence of clinically relevant AL due to necrosis of the descending colon or anastomosis. Upon blind review, perfusion assessment using IOFA was reproducible.

Abstract
OBJECTIVE Robotic surgery (RS) has been increasingly used for the resection of rectal cancer, and its advantages over laparoscopic surgery (LS) have been demonstrated. However, few studies focused on the severity of postoperative complications. This study aimed to compared the postoperative complications within 30 days after RS over LS according to the Clavien-Dindo (C-D) classification. METHODS A literature research of PubMed, Embase, Cochrane Library and Web of Science were systematically performed. The studies comparing the complications of RS and LS for rectal cancer based on the C-D classification were enrolled. Primary outcomes were C-D grade III, IV, V, III-V (severe complications). RESULTS Seventeen studies (3193 patients) were included in the final analysis: 1554 underwent RS and 1639 underwent LS. The RS group was associated with significantly lower rates of severe complications (OR = 0.69, 95% CI 0.53-0.90, P = 0.005), C-D grade IV (OR = 0.69, 95% CI 0.53-0.90, P = 0.005), and anastomotic leak (OR = 0.66, 95% CI 0.48-0.91, P = 0.01). There was no significant difference in C-D grade III, C-D grade I, II, I-II (minor complications), overall complications, bleeding, wound complications, postoperative ileus, urinary retention, readmission, reoperation between two groups. CONCLUSIONS Robotic surgery is safe for rectal cancer and may be an effective alternative to laparoscopic surgery, with lower rates of severe complications, C-D grade IV, and anastomotic leak. Further large randomized controlled trials are necessary to confirm this conclusion.

Abstract
BACKGROUND In patients with ultralow rectal cancer, surgical resection of the tumor without impairing sphincter function remains a technical challenge. The purpose of this study was to describe a new technique of transanal natural orifice specimen extraction (NOSE) surgery using our independently developed devices, aiming to achieve precise cancer resection and preserve sphincter function in patients with ultralow rectal cancer. METHODS Precision functional sphincter-preserving surgery (PPS) was performed on nineteen patients with ultralow rectal cancer between June 2019 and April 2020. With the help of our independently developed devices, surgeons directly and accurately removed the lower edge of the tumor and retained healthy rectal tissue on the nontumorous side. Hand-sewn anastomosis with a mattress suture was used to achieve sturdy anastomosis. Preoperative baseline characteristics, operative details, 90-day postoperative complications, costs, and anal function score at 6 months after surgery were documented. RESULTS Nineteen ultralow rectal cancer patients with a median distance to the dentate line of 2.0 cm successfully underwent PPS without serious postoperative complications. Six out of nineteen patients (31.6%) received a prophylactic stoma. The average cost was 62164.1 yuan. At 6 months after surgery, the average Wexner anal function score and the average Vaizey score were both 3 points. CONCLUSIONS PPS can be employed to precisely resect rectal tumors and preserve sphincter function in ultralow rectal cancer patients. The use of our devices enhanced surgical efficiency, reduced the need for prophylactic stoma, reduced surgery-related costs, and prevented abdominal surgical incisions.

Abstract
Objective This study was performed to identify risk factors for anastomotic leakage (AL) and combine these factors to create a prediction model for the risk of AL after laparoscopic rectal cancer resection. Methods This retrospective study involved 185 patients with rectal cancer who underwent laparoscopic resection from March 2012 to February 2017. Five risk factors were analyzed by multivariate analysis. A prediction model was established by combining the risk factors from the multivariate analysis, and the accuracy of the model was evaluated by a receiver operating characteristic curve. Results The overall AL rate was 17.84%. The multivariate analysis identified the following independent risk factors for AL: high body mass index (odds ratio [OR], 3.009; 95% confidence interval [CI], 1.127–7.125), preoperative radiochemotherapy (OR, 3.778; 95% CI, 1.168–12.219), larger tumor size (OR, 2.710; 95% CI, 1.119–6.562), and longer surgical time (OR, 2.476; 95% CI, 1.033–5.932). We established a prediction model that can evaluate the risk of AL by determining the predictive probability. The area under the curve for the model’s predictive performance was 0.70 (95% CI, 0.598–0.795). Conclusion A prediction model was created to predict the risk of AL after laparoscopic rectal cancer resection.

Abstract
Radiofrequency ablation (RFA) is one of the safe and effective treatments of colorectal cancer with liver metastasis, which has the advantages of minimally invasive, fewer complications, short hospitalization time and repeatable operation. A special case with advanced transverse colon carcinoma was treated by RFA in our center. All the procedures were performed, which were recommended by the guideline. An intestinal perforation occurred on the second day after the RFA, then surgeon performed emergency surgery, unfortunately, anastomotic leakage occurred on the 21st day after the operation, yet after conservative medical treatment, the patient achieved remission of symptoms and discharged from the hospital. Rare complications occurred after RFA in the treatment of colorectal cancer with liver metastasis are unpredictable, which could affect the efficacy of RFA and performance status of patients. Further investigation of the mechanism of these complications is warranted urgently, which might offer more effective methods against these rare complications.

Abstract
Purpose of the present study is to analyze risk factors for adverse events after elective colorectal resection. A wide range of adverse events after elective colorectal surgery was reported, anastomotic leakage (AL) and related morbidity and mortality being the most feared ones. Clear definition of risk factors is crucial to limit the related mortality. Prospective, 1-year multicenter enrollment of 1546 elective colorectal resections with anastomosis. Endpoints were anastomotic leakage (AL), overall morbidity, major morbidity and mortality rates (ClinicalTrials.gov; Identifier: NCT03560180). AL rate was 4.92%. Overall morbidity, major morbidity and mortality rates were 30.20%, 9.76% and 1.29%, respectively. Intra- and/or postoperative blood transfusion(s) was the only variable independently influencing all the endpoints: Odds ratios (OR) were 8.15 for AL, 19.33 for overall morbidity, 10.17 for major morbidity and 3.70 for mortality); overall morbidity rates were also independently influenced by American Society of Anesthesiologists class III vs I-II and extra- vs intra-corporeal anastomosis (OR 1.57 and 1.49, respectively); major morbidity rates were also independently influenced by female vs male gender and by the length of the procedure (OR 0.60 and 1.004, respectively); mortality rates were also independently influenced by increasing age (OR 1.16). This study clearly identifies intra- and/or postoperative blood transfusion(s) as an independent risk factor for all adverse events after elective colorectal surgery.

Abstract
BACKGROUND Several univariate and multivariate studies have already identified the number of stapler firings for laparoscopic rectal transection for rectal cancer as an independent risk factor for anastomotic leakage. The aim of this study was to perform a systematic review and meta-analysis of the anastomotic leakage rate in laparoscopic rectal surgery according to the need of using one or two stapler firings for rectal transection. METHODS PubMed, Ovid, the Cochrane Library database and ClinicalTrials.gov were searched. All of the statistical analyses were performed using Revman software. RESULTS Five studies were included (1267 patients). The overall anastomotic leakage rate was 5.5% [0.7-8.4%]. Anastomotic leak occurred in 3.5% (17/491) of the cases where 1 stapler firing was used versus 6.7% (50/786) of the cases in which 2 firings were needed (50/786). Two stapler firings were significantly associated with an increased risk of anastomotic leakage (OR 2.44, 95% CI 1.34-4.42, p = 0.003, I2 = 1%). CONCLUSIONS Our systematic review and meta-analysis suggest that two firings imply a higher rate of anastomotic leak than a single firing after laparoscopic rectal surgery with a double stapling technique. Coloproctologists should strive to reduce the number of linear stapler firings and try to transect the rectum with a single firing.

Abstract
Purpose Narrow pelvis has been considered an adverse factor for postoperative and oncologic outcomes after rectal cancer surgery. The aim of this study was to investigate the validity of using only axial CT scan images to calculate the pelvic cross-sectional area for the prediction of adverse outcomes after rectal cancer surgery. Methods The medical records of patients who underwent rectal cancer surgery were reviewed and analyzed retrospectively. Axial images of CT scan were used to measure the pelvic cross-sectional area. Pelvic surgical site infection (SSI), positive resection margin, and early local recurrence were adopted as end-points to analyze the impact of pelvimetry on surgical outcome. Results The mean pelvic cross-sectional area was 84.3 ± 10.9 cm2. Males had significantly smaller pelvic areas than females (P < 0.001). Comparing pelvic cross-sectional areas according to the surgical outcomes, the results indicated that patients with pelvic SSI and local failure (positive resection margin or local recurrence within 1 year) have significantly smaller cross-sectional-area than SSI and local failure-free patients (P = 0.013 and P = 0.031). A calculated cross-sectional area of 88.8 cm2 was determined as the cutoff value for the prediction of pelvic SSI and/or local failure, which was significant in a validating analysis. Conclusion The pelvic cross-sectional area obtained from a routine axial CT scan image was associated with pelvic SSI, positive resection margin, and early local recurrence. It might be an intuitive, feasible, and easily adoptable method for predicting surgical outcomes.

Abstract
BACKGROUND Anastomotic leakage (AL) is a severe complication of low anterior resection (LAR) for rectal cancer, and effective prevention is urgently needed. In the robotic era, this study aimed to explore the role of innovative techniques in preventing AL in rectal cancer patients undergoing robotic LAR. METHODS From May 2012 to May 2017, a total of 601 patients underwent robotic LAR, with 191 patients participated as control subjects (non-PST group) and 410 patients are subjected to a trinity technique (PST group). The AL rate, short-term and long-term outcomes are analyzed and compared. RESULTS The overall rate of AL was 6.8% out of 601 patients, with Grade B at 5.7% and Grade C at 1.1%, using the ISREC grading system. The PST group presented lower incidence of both overall AL (5.1% vs 10.5%, P = 0.015) and major AL (0.2% vs 3.2%, P = 0.005), when compared with the non-PST group, respectively. Furthermore, the PST group had similar surgical complications (17.3% vs 20.9%, P = 0.286), while with lower re-hospitalization rate (2.7% vs 6.3%, P = 0.038) and reoperation rate (0.2% vs 4.2%, P = 0.001), compared with the non-PST group, respectively. Short-term recovery and long-term oncological outcomes were not significant in the two groups. By multivariate logistic regression models, the risk factors of AL of robotic LAR are confirmed as non-PST technique, estimated blood loss ≥100 mL, anastomosis from anal verge <5 cm, and distal resection margin from tumor <2 cm. CONCLUSIONS The innovative PST technique may shed light on an effective method for preventing occurrence of AL in robotic LAR.

Abstract
BACKGROUND AND AIM If patients with surgically resectable colorectal cancershave synchronous colorectal neoplasms that are difficult to remove by endoscopic mucosal resection, preemptive endoscopic submucosal dissection (ESD) can avoid excessive colorectal resection. The aim of this study was to evaluate the efficacy of the strategy of preemptive ESD and surgery for synchronous colorectal neoplasms. METHODS Patients who underwent preemptive ESD and surgery for synchronous colorectal neoplasms between September 2002 and December 2017 were enrolled in this retrospective cohort study. The proportion of cases in which extended surgery could be avoided following curative ESD was calculated. Clinicopathological characteristics were evaluated for all patients and long-term outcomes were analyzed for patients who underwent curative ESD and surgery. RESULTS A total of 45 consecutive patients with 47 endoscopically-resected lesions and 46 surgically-resected lesions were retrospectively evaluated. Curative ESD was achieved in 44 lesions (93.6%) and an extended surgical procedure could be avoided in 42 patients (93.3%). Intraoperative perforation occurred in two lesions (4.3%), delayed perforation in one lesion (2.1%), and delayed bleeding in two lesions (4.3%). Final stages were as follows: stage 0, 3 patients (7.1%); stage I, 23 patients (54.8%); stage II, 3 patients (7.1%); stage III, 12 patients (28.6%); and stage IV, 1 patient (2.4%). The 5-year overall survival rates of patients with all pathological stages, stage 0-II, and stage III-IV were 93.7%, 100%, and 79.1%, respectively. CONCLUSION The strategy of preemptive ESD and surgery for synchronous colorectal neoplasms is minimally invasive and has a favorable prognosis.

Abstract
Minimally invasive surgery for total mesorectal excision (TME) remains technically challenging due to poor maneuverability within the pelvis, which makes extremely difficult to introduce a laparoscopic stapler (LS) for the rectal transection. We aim to perform a systematic review and meta-analysis on robotic TME after the use of robotic stapler (RS) or LS after robotic TME. A systematic literature search was performed using PubMed, MEDLINE, and Cochrane Database. Participants who underwent robotic anterior resection were considered following these criteria: (1) studies comparing RS and LS; (2) studies reporting the rate of anastomotic leakage (AL). The primary outcome was the risk of AL. Secondary outcomes included the number of firings of stapler needed. A meta-analysis based on Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement was performed. A total of 4 studies including 391 patients (LS = 251, RS = 140) were included for analysis. Regarding the number of firings, overall results suggest that the rectal stapling was achieved with less firings in the RS group, but the difference is not significant [risk difference, (95% CI) 0.42 (- 0.13, 0.97)]. There was a 56% increased odds of AL for LS compared with RS; however, this was not statistically significant (OR: 1.56; 95% CI 0.59, 4.14). With the current literature evidence, the present study could not demonstrate a clear benefit of the RS over the LS. Although the development of an AL is multifactorial and unpredictable, our data may suggest that the use of the RS could help reducing the risk of AL. There is a need of future randomized clinical trial to assess the possible benefits of the RS.

Abstract
BACKGROUND Natural orifice specimen extraction (NOSE) surgery has been widely implemented in colorectal cancer surgery due to its good short-term efficacy. However, anastomotic leakage (AL) is a serious postoperative complication in colorectal cancer, and the risk factors for this complication after NOSE surgery have rarely been investigated. The aim of this study was to explore the predictive factors for AL after laparoscopic resection with transrectal NOSE for rectal cancer and sigmoid colon cancer. METHODS A total of 208 patients who underwent total laparoscopic resection with transrectal NOSE for rectal cancer and sigmoid colon cancer from January 2014 to June 2019 were systematically reviewed. Univariate and multivariate analyses were performed to identify the relevant risk factors. RESULTS The rate of AL was 10.1% (21 of 208 patients). The univariate analyses showed that male sex (85.7% vs 57.8%, P = .013), the distance from the anal verge (10.5 vs 14.5 cm, P = .011), and a duration of operation ≥140 min (71.4% vs 29.4%, P<.001) were associated with an increased incidence of AL. The multivariate analysis showed that a duration of operation ≥140 min (OR = 5427, 95% CI = 1.355-21.727, P = .017) was an independent risk factor for AL. CONCLUSION A duration of operation ≥140 min is a possible risk factor for AL after total laparoscopic resection with transrectal NOSE for colorectal cancer.

Abstract
BACKGROUND The aim of this study was to evaluate the efficacy of indocyanine green (ICG) fluorescence angiography with respect to the anastomotic leakage rate for patients undergoing colorectal operations. METHODS This prospective cohort involved patients who underwent colorectal surgery between August 2018 and September 2019. ICG was injected after colonic transection. Vascular perfusion was observed by ICG fluorescence system before completing anastomosis. Data was compared with those by subjective visual evaluation. The primary outcome was anastomotic leakage rate within 30 days from surgery. RESULTS A total of 131 patients were enrolled, of which ICG was injected in 63 of them. Demographic data were similar between the two groups. There were two (3.23%) and three (4.35%) anastomotic leaks in the ICG and non-ICG group respectively (p = 1.000). Change of resection plane occurred in one patient in the ICG group. There was no ICG related toxicity or adverse events. CONCLUSION ICG fluorescent imaging is a feasible and safe tool to assess colonic vascularisation for patients undergoing colorectal surgery. However, it did not significantly lower the anastomotic leakage rate. ICG should not be routinely used in colorectal surgery before an available large scale randomised controlled trial to prove any clinical benefits.

Abstract
BACKGROUND The purpose of this study was to test use of the Dutch leakage score (DLS), serum C-reactive protein (CRP) and serum procalcitonin (PCT) in the diagnosis of anastomotic leakage (AL) after elective colorectal resection in a prospective observational study. METHODS Patients undergoing elective colorectal resection with anastomosis in 19 centres were enrolled over a 1-year period from September 2017. The DLS and CRP and PCT levels were evaluated on postoperative day (POD) 2, POD3 and POD6. Statistical analysis, including determination of the area under the receiver operating characteristic (ROC) curve (AUC), was performed for the primary endpoint of AL; secondary endpoints were morbidity and mortality rates ( ClinicalTrials.gov identifier: NCT03560180). RESULTS Among 1546 patients enrolled, the AL rate was 4·9 per cent. Morbidity and mortality rates were 30·2 and 1·3 per cent respectively. With respect to AL, DLS performed better than CRP and PTC levels on POD2 and POD3 (AUC 0·75 and 0·84), whereas CRP levels were documented with better AUC values on POD6 (AUC 0·81). Morbidity was poorly predicted, whereas mortality was best predicted by PCT on POD2 (AUC 0·83) and by DLS on POD3 and POD6 (AUC 0·87 and 0·98 respectively). Overall, the combination of positive PCT, CRP and DLS values resulted in a probability of AL of 21·3 per cent on POD2, 33·4 per cent on POD3, and 47·1 per cent on POD6. However, the combination of their negative values excluded AL in 99·0 per cent of cases on POD2, 99·3 per cent on POD3, and 99·2 per cent on POD6. CONCLUSION DLS and CRP level are good positive and excellent negative predictors of AL; the addition of PCT improved the predictive value for diagnosis of AL.

Abstract
BACKGROUND AND OBJECTIVE Anastomotic leakage is one of the most serious complications after laparoscopic low anterior resection Low Anterior Resection (LAR) for rectal cancers. The purpose of this study was to evaluate the effectiveness of a transanal drainage tube placed for the prevention of anastomotic leakage after laparoscopic LAR. METHODS The clinical data of 220 patients with rectal cancer who underwent laparoscopic LAR using the double stapling technique Double Stapling Department of Colorectal Surgery, National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College Technique (DST) from Jun 2017 to Dec 2018 were analyzed retrospectively at our institution. A transanal drainage tube was placed after anastomosis in 120 patients (TDT group). Another 100 patients were operated on without a transanal drainage tube (NTDT group). Clinicopathological and surgical factors, the frequencies of anastomotic leakage and re-operation after leakage were compared between the two groups. RESULTS Patient age, gender, body mass index, American Society of Anesthesiologists (ASA) score, previous abdominal surgery, intraoperative blood loss, tumor size, tumor stage, specimen length, distance of tumor from the anal verge, and operative time were comparable between the two groups. Overall rate of leakage was 4.5% (10/220). The frequency of leakage was 3.3% (4/120) in TDT group and was 6.0% (6/100) in NTDT group. The rate of leakage was significantly lower in TDT group (p<0.05). Furthermore, the re-operation rate for symptomatic anastomotic leakage was 50.0% (2/4) in TDT group, while in contrast it was 83.3% (5/6) in NTDT group. The rate of re-operation was lower in TDT group than NTDT group (p<0.05). CONCLUSIONS The use of a transanal drainage tube in laparoscopic LAR for rectal cancer is a simple and effective method for prevention of anastomotic leakage and decreases the rate of re-operation after symptomatic leakage.

Abstract
Background: Anastomotic leakage (AL) is arguably the most troublesome complication of anterior resection (AR). In recent years, however, indocyanine green (ICG) fluorescence imaging has been recently used to evaluate blood flow in the anastomosis site, and it has been suggested that AL may be predicted. We reported the effectiveness of predicting AL in colorectal cancer surgery by observing a quantitative laparoscopic ICG fluorescence imaging for the first time. The purpose of this study was to predict the risk of postoperative AL by quantitative laparoscopic ICG fluorescence imaging focused on the rectal stamp, which is one of the major causes of AL in AR, and to construct diverting stoma (DS) only in appropriate cases. Methods: We studied the 25 patients who underwent elective laparoscopic AR for rectal cancer at our hospital between July 2016 and June 2017. Before enforcing double-stapling technique anastomosis, we injected ICG intravenously, and laparoscopically evaluated blood flow on the rectal stump. We analyzed quantitatively the relationship between various parameters and AL. Results: Median T0, from when the ICG was injected intravenously and the ICG disappeared from the injection route to the rise of the histogram of intensity, in AL group was significantly longer than that in non-AL group (P = .03). There were no other significant differences between AL and non-AL groups. Conclusions: T0 was longer in patients with AL than in those without. If prolonged T0 can be recognized intraoperatively, it will be possible to construct DS for appropriate patients only.

Abstract
OBJECTIVE Anastomotic leakage (AL) is one of the most devastating complications of rectal cancer surgery. Not only does AL result in reduced quality of life, extended hospitalization and impaired defecatory function, it also has a high local recurrence rate. In this study, we investigated risk factors for AL as it may help to decrease its occurrence and improve patient outcomes. METHODS This study was a retrospective, single-institution study of rectal cancer patients who underwent elective low anterior resection between April 2002 and February 2018 at Fukushima Medical University Hospital. Patients were divided into two groups according to the presence of AL. Patient-, tumor-, and surgery-related variables were examined using univariate and multivariate analyses. RESULTS One hundred sixty-one patients, average age 63.5±11.5 years, were enrolled in the study. The overall AL rate was 6.8% (11/161). In the univariate analysis, modified Glasgow Prognostic Score (mGPS)=2 (p=0.003), use of multiple staplers (≥3 firings) for rectal transection (p=0.001) and intraoperative bleeding (≥250 g) were significantly associated with AL incidence. Multivariate analysis identified that mGPS = 2 (odds ratio [OR]: 19.6, 95% confidence interval [CI]: 2.96-125.00, p=0.002) and multiple firings (OR: 18.19, CI: 2.31-111.11, p=0.002) were independent risk factors for AL. CONCLUSION Higher mGPS score and multiple firings were independent risk factors for AL.

Abstract
PURPOSE Proper transection of the distal rectum is important for reconstruction of bowel continuity in rectal cancer surgery. In this study, we introduced a modified technique for ligation of the distal rectum, and investigated its safety and efficiency to facilitate the rectum transection. METHODS After complete mobilization and transection of the mesorectum, a cable tie was carefully positioned distal to the tumor, followed by washout and transecting the rectum with a linear stapler. From September 2017 to June 2018, consecutive 67 mid-low rectal cancer patients with laparoscopic anterior resection underwent this technique. Clinical data of these patients, including number of firings, pathological and operative variables, and postoperative outcomes, were compared with those of 132 consecutive patients who underwent traditional surgery from January 2016 to August 2017. RESULTS Compared with the traditional method, cable tie ligation significantly reduced the number of firings (1.1 ± 0.32 vs. 1.3 ± 0.52, p < 0.001). A very high ratio of one firing transection of rectum was observed in the cable tie group (94.0% vs. 68.9%, p < 0.001), even in patients with tumor at or below the peritoneal reflection (90.2% vs. 54.4%, p < 0.001), in male patients (95.5% vs. 65.8%, p < 0.001), and in obese patients (93.8% vs. 64.9%, p = 0.005). The mean distal margin was longer in the cable tie group (3.19 ± 1.77 cm vs. 2.54 ± 1.36 cm, p = 0.005), with no positive distal margin observed. The operation time, quality of mesorectum, and morbidity between two groups were comparable. Two leaks (3.0%) in the cable tie group were observed, similar to 3.8% in the control. CONCLUSIONS Ligation of the rectum with a cable tie reduces the number of cartridges, and increases the rate of one stapler firing for rectal transection, even in those difficult cases like male, overweight, and low rectal cancer patients. It is also useful for occlusion of the rectum before washout. It is safe, feasible, and worthwhile for popularization. TRIAL REGISTRATION Registered at ClinicalTrial.gov, number NCT03570684.

Abstract
BACKGROUND The da Vinci Surgical System (Intuitive Surgical, Sunnyvale, CA) was introduced to overcome the limitations of single-incision laparoscopic surgery, which is challenging due to its restrictions regarding triangulation and retraction. The purpose of this article is to describe the initial experience with single-incision surgery using the da Vinvci Single-Port Platform (dVSP). METHODS The medical records of patients with colorectal disease, who underwent single-incision robotic surgery using the dVSP, were retrospectively reviewed. RESULTS Five patients with appendiceal and colorectal cancer, and two with diverticulitis were enrolled. All procedures were completed using a pure single-incision approach, with an exception for low anterior resection. There were two minor complications. For patients with colorectal cancer, the number of retrieved lymph nodes and status of the resection margin were acceptable, and cosmetic results were satisfactory. CONCLUSION The dVSP is a novel surgical platform that can be used as an alternative surgical modality for colorectal surgery.

Abstract
OBJECTIVE To determine the incidence of anastomotic-related morbidity following Transanal Total Mesorectal Excision (TaTME) and identify independent risk factors for failure. BACKGROUND Anastomotic leak and its sequelae are dreaded complications following gastrointestinal surgery. TaTME is a recent technique for rectal resection, which includes novel anastomotic techniques. METHODS Prospective study of consecutive reconstructed TaTME cases recorded over 30 months in 107 surgical centers across 29 countries. Primary endpoint was "anastomotic failure," defined as a composite endpoint of early or delayed leak, pelvic abscess, anastomotic fistula, chronic sinus, or anastomotic stricture. Multivariate regression analysis performed identifying independent risk factors of anastomotic failure and an observed risk score developed. RESULTS One thousand five hundred ninety-four cases with anastomotic reconstruction were analyzed; 96.6% performed for cancer. Median anastomotic height from anal verge was 3.0 ± 2.0 cm with stapled techniques accounting for 66.0%. The overall anastomotic failure rate was 15.7%. This included early (7.8%) and delayed leak (2.0%), pelvic abscess (4.7%), anastomotic fistula (0.8%), chronic sinus (0.9%), and anastomotic stricture in 3.6% of cases. Independent risk factors of anastomotic failure were: male sex, obesity, smoking, diabetes mellitus, tumors >25 mm, excessive intraoperative blood loss, manual anastomosis, and prolonged perineal operative time. A scoring system for preoperative risk factors was associated with observed rates of anastomotic failure between 6.3% to 50% based on the cumulative score. CONCLUSIONS Large tumors in obese, diabetic male patients who smoke have the highest risk of anastomotic failure. Acknowledging such risk factors can guide appropriate consent and clinical decision-making that may reduce anastomotic-related morbidity.

Abstract
INTRODUCTION Laparoscopic colorectal resection is becoming the gold standard for treating colorectal cancers because it offers superior short-term and comparable long-time outcomes compared to open surgery. Intraoperative colonoscopy (IOC) is increasingly performed for tumor localization and mucosal assessment. The aim of this report was to review the safety and efficacy of IOC in laparoscopic colorectal surgery. METHOD A MEDLINE search of studies of IOC in laparoscopic colorectal surgery was performed. We focused on three aspects of IOC use: (i) IOC for intraoperative tumor localization; (ii) colonic irrigation and IOC for obstructive left-sided colorectal cancers; and (iii) IOC for assessing colorectal anastomosis. RESULTS During laparoscopic colorectal surgery, IOC enables accurate localization of early mucosal tumors, detection of lesions in the proximal unexamined colon for obstructive left-sided cancer, and visual assessment of anastomosis. Additionally, IOC allows for proper surgical resection, management of concomitant lesions, immediate maintenance of hemostasis, suture repair of leaks, and the creation of a protective stoma as necessary. CONCLUSIONS Intraoperative colonoscopy is beneficial in laparoscopic colorectal surgery. Experienced surgical endoscopists should be trained to safely perform IOC.

Abstract
BACKGROUND Insufficient vascular supply is one of the main causes of anastomotic leak in colorectal surgery. Intraoperative indocyanine-green (ICG) angiography has been shown to provide information on tissue perfusion, identifying a well-perfused location for colonic and rectal transections, and thus possibly reducing the leak rate. Aim of this study was to evaluate the usefulness of intraoperative assessment of anastomotic perfusion using ICG angiography in patients undergoing left-sided colon or rectal resection with colorectal anastomosis. METHODS This randomized trial involved 252 patients undergoing laparoscopic left-sided colon and rectal resection randomized 1:1 to intraoperative ICG or to subjective visual evaluation of the bowel perfusion without ICG. The primary aim was to assess whether ICG angiography could lead to a reduction in anastomotic leak rate. Secondary outcomes were possible changes in the surgical strategy and postoperative morbidity. RESULTS After randomization, 12 patients were excluded. Accordingly, 240 patients were included in the analysis; 118 were in the study group, and 122 in the control group. ICG angiography showed insufficient perfusion of the colic stump, which led to extended bowel resection in 13 cases (11%). An anastomotic leak developed in 11 patients (9%) in the control group and in 6 patients (5%) in the study group (p = n.s.). CONCLUSIONS Intraoperative ICG fluorescent angiography can effectively assess vascularization of the colic stump and anastomosis in patients undergoing colorectal resection. This method led to further proximal bowel resection in 13 cases, however, there was no statistically significant reduction of anastomotic leak rate in the ICG arm.

Abstract
BACKGROUND One of the major cause of anastomotic leakage (AL) in anterior resection of the rectum is insufficient blood flow of the remnant colon. The indocyanine green fluorescence system (ICG-FS) can visualize the blood flow of organs intra-operatively. The aim of this study is to investigate the usefulness of ICG-FS for evaluating the blood flow of the remnant colon in laparoscopic anterior resection. MATERIALS AND METHODS Rectal cancer patients (n=24) who underwent laparoscopic anterior resection were included in this study. After resection of the rectum, 7.5mg of ICG was administered intravenously, and the blood flow of the oral stump was evaluated by the ICG-FS. The relationship between the fluorescence time (FT) of the oral stump and AL was investigated retrospectively. RESULT Two of twenty-four patients (8.3%) suffered AL. The FT of these two cases were over 60 seconds. In the case with the FT was over 80 seconds, we performed additional resection of the late fluorescence portion of the remnant colon and could avoid AL. In patients whose FT was under 60 seconds, no patients suffered AL. CONCLUSION ICG-FS may be useful for evaluating the blood flow of the remnant colon to avoid AL in laparoscopic anterior resection.

Abstract
AIM Anastomotic leakage (AL) is one of the most feared postoperative complications after anterior resection (AR) of rectal cancer. An adequate blood supply at the anastomotic site is regarded as a prerequisite for healing. We hypothesize that the Aortic Calcification Index (ACI) might reflect the severity of atherosclerosis in patients, and thereby be a risk factor for AL. METHOD AL was investigated retrospectively according to the definition of the International Study Group of Rectal Cancer in 423 rectal cancer patients who underwent anterior rectal resection. The ACI was measured by preoperative abdominal CT scan. The cross-section of the aorta was evenly divided into 12 sectors, the number of calcified sectors was counted as the calcification score of each slice. Lasso logistic regression and multivariate regression analysis were used to identify risk factors for AL. RESULTS The percentage of AL after AR was 7.8% (33/423); the mortality of patients who sustained a leak was 3.0% (1/33). Patients with a high ACI had a significantly higher percentage of AL than patients with low ACI (11.2% vs 5.6%, P = 0.04). Among patients with AL, a higher ACI was associated with greater severity of AL (the ACI of patients with grade A leakage, grade B leakage and grade C leakage was 0.5% ± 0.2%, 11.5% ± 9.2% and 24.2% ± 21.7%, respectively; P = 0.008). After risk adjustment, multivariate regression analysis showed that a higher ACI was an independent risk factor for AL (OR 2.391, P = 0.04). CONCLUSION A high ACI might be an important prognostic factor for AL after AR for rectal cancer. Confirmatory studies are required.

Abstract
Background In recent years, laparoscopic surgery has been widely used for rectal cancer. In laparoscopic rectal surgery, a double-stapling technique (DST) anastomosis using a stapling device is considered a relatively difficult procedure. Postoperative anastomotic leakage (AL) is a major complication related to patients’ quality of life and prognosis. Methods This study was a retrospective, single-institution study of 101 rectal cancer patients who underwent laparoscopic low anterior resection (LAR) with DST anastomosis (excluding simultaneous resection of other organs and construction of protective diverting stoma) between February 2008 and November 2017 at the Gifu University Graduate School of Medicine. This study aimed to identify risk and early predictive factors of AL. Results Among 101 patients, symptomatic AL occurred in 13 patients (12.9%), of whom 10 were male and 3 were female. Their median BMI was 22.7 kg/m2 (range, 17.9–26.4 kg/m2). Among the pre- and intraoperative factors, AL was significantly associated with tumor location (lower rectum), distance from the anal verge (< 6 cm), intraoperative blood loss (≥ 50 ml), and the number of linear staples (≥ 2) in univariate analysis. In multivariate analysis, only intraoperative blood loss (≥ 50 ml, odds ratio [OR] 4.59; 95% confidence interval [CI] 1.04–19.52; p = 0.045) was identified as an independent risk factor for AL. Among the postoperative factors, AL was significantly associated with tachycardia-POD1 (≥ 100 bpm), CRP-POD3 (≥ 15 mg/dl), fever on postoperative day (fever-POD) 3 (≥ 38 °C), and first defecation day after surgery (< POD3) in univariate analysis. In multivariate analysis, fever-POD3 (≥ 38 °C, OR 30.97; 95% CI 4.68–311.22; p = 0.0003) and first defecation day after surgery (< POD3, OR 5.82; 95% CI 1.34–31.30; p = 0.019) were identified as early predictive factors for AL. Conclusion In this study, intraoperative blood loss was an indicator of difficulty in a transection and anastomosing procedure, and fever-POD3 and early first defecation day after surgery were independent early predictive factors for AL. Careful surgery using an appropriate technique and standardized procedures with minimal bleeding and careful postoperative management paying attention to fever and defecation may prevent the onset and severity of AL.

Abstract
BACKGROUND Anastomotic leakage (AL) is a serious complication after anterior resection. The purpose of this study was to determine the role of microvascular density (MVD) in AL and to develop a nomogram to accurately predict AL. METHODS This study retrospectively enrolled 477 consecutive patients who underwent anterior resection for rectal cancer from January 2011 to January 2019. Tissue samples of the resection margins were assessed for MVD. Univariate and multivariate regression analyses were used to identify the risk factors for AL. RESULTS The incidence of clinical AL was 6.7%. MVD in the distal margin was associated with AL (P < .001). Univariate and multivariate regression analysis identified the following variables as independent risk factors for AL: preoperative albumin ≤35 g/L (odds ratio [OR] = 2.511), neoadjuvant treatment (OR = 3.560), location of tumor ≤7 cm (OR = 3.381), blood loss ≥100 mL (OR = 2.717), and MVD in the distal margin ≤20 (OR = 4.265). Then, a nomogram including these predictors was developed. The nomogram showed good discrimination (AUC = 0.816) and calibration (concordance index = 0.816). The decision curve analysis demonstrated that the nomogram was clinically useful. CONCLUSIONS MVD in the distal margin is closely associated with AL. The nomogram can be used for individualized prediction of AL after anterior resection for patients with rectal cancer.

Abstract
INTRODUCTION Anatomical evaluation of the splenic flexure vein is essential for complete mesocolic excision with central vascular ligation when treating patients with splenic flexure cancer. Although there have been several studies relating to the arterial branches of the splenic flexure, very limited data are available regarding the variation in venous anatomy in this region. METHODS Sixty-six patients with colorectal cancer who underwent preoperative 3-D CT between April 2016 and April 2017 were included in this retrospective study. The pattern of the venous drainage of the splenic flexure and its association with the inferior border of the pancreas were evaluated. RESULTS The inferior mesenteric vein flowed into the splenic vein in 32 patients (48.5%), into the superior mesenteric vein in 27 patients (40.9%), and into the confluence of splenic vein and superior mesenteric vein in 7 patients (10.6%). The splenic flexure vein joined the inferior mesenteric vein in 62 patients (93.9%), the splenic vein in 2 patients (3.0%), and the middle colic vein in 2 patients (3.0%). The splenic flexure vein flowed into the inferior mesenteric vein below the level of the inferior border of the pancreas in 58 patients (90.6%) and above it in 4 patients (6.3%). CONCLUSION Preoperative evaluation of the venous pattern of the splenic flexure on 3-D CT is useful before complete mesocolic excision with central vascular ligation to avoid intraoperative bleeding during splenic flexure cancer surgery.

Abstract
Colon leakage score (CLS) was introduced as a clinical tool to predict anastomotic leakage (AL) in patients who underwent left-sided colorectal surgery, but its clinical validity has not been widely studied. We evaluated the clinical utility of CLS and developed a modified CLS (m-CLS). In total, 566 patients who underwent left-sided colorectal surgery were enrolled and categorized into training (n = 396) and validation (n = 170) sets via random sampling. Using CLS variables, the least absolute shrinkage and selection operator (LASSO) regression model was applied for variable selection and predictive signature building in the training set. The model's performance was validated in the validation set. The predictive powers of m-CLS and CLS were compared by the area under the receiver operating characteristic (AUROC) curve in the overall group. Twenty-three AL events (4.1%) were noted. The AL group had a significantly higher mean CLS than the No Leakage group (12.5 vs. 9.6, p = 0.001). Five clinical variables were selected and used to generate m-CLS. The predictive performance of m-CLS was similar in training and validation sets (AUROC 0.838 vs. 0.803, p = 0.724). In the overall set, m-CLS was significantly predictive of AL and performed better than CLS (AUROC 0.831 vs. 0.701, p = 0.008). In conclusion, LASSO-model-generated m-CLS could predict AL more accurately than CLS.

Abstract
BACKGROUND The transection of rectum and fashioning of anastomosis is a crucial step in laparoscopic total mesorectal excision (TME) and the double-stapling technique (DST) is often employed. This study aimed to evaluate the factors that were associated with difficult DST. METHOD Cases of laparoscopic TME were retrospectively reviewed. The clinico-anatomical parameters were retrieved from a prospectively maintained database. In addition, pelvic dimensions were taken by reviewing the magnetic resonance imaging scan. The number of stapler cartridges used for intracorporeal transection of rectum was used as a surrogate for the level of difficulty of DST and its relationship with various parameters were evaluated. RESULTS There were a total of 121 consecutive cases analyzed. The mean number of stapler cartridges used was 2.1 ± 0.7. Pelvic inlet (p = 0.002) and tumor height (p = 0.015) were predictors of the number of cartridges used, R2 = 0.366. A model was developed to predict the likelihood of transecting the rectum with two or less stapler cartridges, which included the following parameters: gender, pelvic inlet, interspinous distance, intertuberous distance, and tumor height. The predicted probability also correlated with overall operation time (p = 0.009) and anastomotic leakage (p = 0.023). CONCLUSION The difficulty of DST was associated with patient's clinico-anatomical factors. Surgeons can consider other feasible alternatives, like transanal anastomosis, when a technically challenging DST is anticipated.

Pressurized intraperitoneal aerosol chemotherapy (PIPAC) might increase the risk of anastomotic leakage compared to HIPEC: an experimental study. Surg Endosc 2019; 34:2939-2946.

Abstract
BACKGROUND Pressurized intraperitoneal aerosol chemotherapy (PIPAC) and hyperthermic intraperitoneal chemotherapy (HIPEC) are technics proposed to treat patients with peritoneal carcinomatosis, in different settings. There is some concern about an over-risk of anastomotic leakage (AL) with PIPAC jeopardizing a combination with cytoreductive surgery. This study used a healthy swine model to compare the postoperative AL rate between PIPAC and HIPEC with digestive resection and to analyze macrocirculation and microcirculation parameters. METHODS Segmental colonic resection with a handsewn anastomosis was performed on 16 healthy pigs; 8 pigs had a PIPAC procedure with 7.5 mg/m2 cisplatin (PIPAC group), and 8 pigs had a closed HIPEC procedure with 70 mg/m2 cisplatin and 42 °C as the target intraperitoneal temperature (HIPEC group). Pigs were kept alive for 8 days, then sacrificed and autopsied to look for AL, which was defined as local abscess or digestive fluid leakage when pressure was applied to the anastomosis. Food intake, weight, and core temperature were monitored postoperatively. Macrocirculation (heart rate, systolic blood pressure) and microcirculation parameters (percentage of perfused vessels, perfused vessels density, DeBacker score) were evaluated intraoperatively at five timepoints. Results were compared between pigs with AL and those without. RESULTS The HIPEC group had no AL, but 3 of 8 pigs (37.5%) had AL in the PIPAC group (p = 0.20). Heart rate and core temperature showed perioperative increases in the HIPEC group. Intraoperatively, heart rate was higher in the HIPEC group at the two last timepoints (123 vs. 93 bpm, p = 0.031, and 110 vs. 85 bpm, p = 0.010, at timepoints 3 and 4, respectively). Other macrocirculatory and microcirculatory parameters showed no significant differences. CONCLUSION In this healthy swine model, PIPAC might have increased AL incidence compared to HIPEC. This potential over-risk did not seem to be related to changes in the microcirculation. PIPAC should probably not be used with digestive resection and should be avoided in cases of perioperative serosal injury.

Ann Surg Treat Res 2019; 97:74-82.

Abstract
Purpose Colon perfusion status is one of the most important factors for the determination of postoperative anastomotic complications. Colonic hypoperfusion can be induced by inferior mesenteric artery (IMA) ligation in some patients. This study aimed to evaluate atherosclerotic risk assessment and vascular parameters of CT angiography as predictors of colonic hypoperfusion. Methods This prospective study was conducted at a tertiary referral hospital and included 46 rectosigmoid colon cancer patients undergoing laparoscopic anterior resection between August 2013 to July 2014. Atherosclerotic risk scores were assessed using the Framingham cardiovascular risk score system. The IMA length, branching pattern, atherosclerotic calcification, and intermesenteric artery and mesenteric vascular diameters were evaluated using CT angiography. Mesenteric marginal artery pressures were measured before and after IMA clamping. The mean arterial pressure (MAP) index was calculated by dividing the mesenteric marginal MAP into the systemic MAP to determine the mesenteric hypoperfusion status after IMA clamping. A critically low MAP index was defined as <0.4. Results Critically low MAP index (<0.4) was observed in 6 cases (13.0%) after IMA clamping. Atherosclerotic calcification of the IMA and superior mesenteric artery occurred in 11 (23.9%) and 5 patients (10.9%), respectively. Low MAP index was associated with high atherosclerotic risk score and short IMA length, rather than atherosclerotic calcification and other vascular parameters of the major mesenteric arteries. Multivariate analysis indicated that high atherosclerotic risk and short IMA length were independent predictors of critically low MAP index. Conclusion Atherosclerotic risk assessment and IMA length were useful predictors of the mesenteric hypoperfusion status following IMA ligation during laparoscopic rectosigmoid colon surgery.
