Abstract
Purpose As the normal colon epithelium differentiates into adenoma, invasive cancer and metastatic cancer, the cell acquires new characteristics such as apoptosis, proliferation, differentiation, invasion and metastasis. Many mechanisms are effective in acquiring these qualities. One of these is the regulation of the functioning of ion channels. This study aimed to examine TRPA1 and TRPC1 expression in colorectal adenocarcinomas showing different degrees of differentiation. Patients and Methods We examined the biopsy specimens of 60 patients diagnosed with colorectal adenocarcinomas, including those of patients with well-differentiated (n = 20), moderately differentiated (n = 20) and poorly differentiated (n = 20) carcinomas. Moreover, 20 biopsy specimens of individuals with normal colonic mucosa were examined. Histoscores were calculated for TRPA1 and TRPC1 based on the extent of diffusion and intensity of immunoreactivity, and these scores were compared statistically. Results A statistically significant increase in both TRPA1 and TRPC1 immunoreactivity was observed in low-grade and high-grade colon adenocarcinomas compared to the control group (p<0.001). A statistically significant decrease in both TRPA1 and TRPC1 immunoreactivity was observed in high-grade colon adenocarcinomas compared to low-grade colon adenocarcinomas (p<0.001). Conclusion TRPA1 and TRPC1 immunoreactivites are increased in colorectal adenocarcinoma tissue compared with the healthy tissue. Furthermore, the immunoreactivity decreases as the grade of cancer increases.

Abstract
INTRODUCTION The aging of the population is one of the most widely studied and impactful social phenomena of this century. Up to 25% of all emergency hospital admissions can be due to diseases that require general surgery. AIMS To describe the experience at the Department of Gastrointestinal Surgery of the Hospital Español, Mexico, in patients above 65 years of age. MATERIALS AND METHODS A retrospective, observational, analytic, and cross-sectional study was conducted that included 595 medical records of geriatric patients that underwent surgical procedures, within the time frame of November 2013 and February 2019. RESULTS A total of 52% (309) of the patients were men and 48% (286) were women. Mean patient age was 75.38 years, with a mode of 73 years, and a maximum age of 100 years. Mean hospital stay was 4.5 days. Postoperative complications presented in 12.77% of the patients, 3.02% of which were severe. Reoperation was required in 13 patients (0.02%). The perioperative mortality rate was 2.02%. CONCLUSIONS The morbidity and mortality rates of the procedures that corresponded to general surgery in our case series were similar to those reported in the literature. A statistically significant number of patients underwent laparoscopic surgery, within the study period.

Abstract
Background Minimally invasive (MI) surgery has revolutionised surgery, becoming the standard of care in many countries around the globe. Observed benefits over traditional open surgery include reduced pain, shorter hospital stay, and decreased recovery time. Gastrointestinal surgery in particular was an early adaptor to both laparoscopic and robotic surgery. Within this review, we provide a comprehensive overview of the evolution of minimally invasive gastrointestinal surgery and a critical outlook on the evidence surrounding its effectiveness and safety. Methods A literature review was conducted to identify relevant articles for the topic of this review. The literature search was performed using Medical Subject Heading terms on PubMed. The methodology for evidence synthesis was in line with the four steps for narrative reviews outlined in current literature. The key words used were minimally invasive, robotic, laparoscopic colorectal, colon, rectal surgery. Conclusion The introduction of minimally surgery has revolutionised patient care. Despite the evidence supporting this technique in gastrointestinal surgery, several controversies remain. Here we discuss some of them; the lack of high level evidence regarding the oncological outcomes of TaTME and lack of supporting evidence for robotic colorectalrectal surgery and upper GI surgery. These controversies open pathways for future research opportunities with RCTs focusing on comparing robotic to laparoscopic with different primary outcomes including ergonomics and surgeon comfort.

Surgical resection of T4 colon cancers: an NCDB propensity score-matched analysis of open, laparoscopic, and robotic approaches. J Robot Surg 2020; 15:701-710.

Abstract
Historically, T4 tumors of the colon have been a contraindication to minimally invasive resection. The purpose of this study was to conduct a National Cancer Database analysis to compare the outcomes after curative treatment for T4 colon cancer between robotic, laparoscopic, and open approaches. The US National Cancer Database was queried for patients with T4 adenocarcinoma of the colon who underwent curative resection. Groups were separated based on approach (open, laparoscopic, robotic). One to one nearest neighbor propensity score matching (PSM) ± 1% caliper was performed across surgical approach cohorts to balance potential confounding covariates. Kaplan-Meier estimation and Cox-proportional hazards regression were used to analyze primary outcome of survival. Secondary outcomes were analyzed by way of logistic regression. Inclusion criteria and PSM identified 876 cases per treatment approach (n = 2628). PSM provided adequate discrimination between treatment cohorts (0.6 < AUC < 0.8) and potential confounding covariates did not significantly differ between cohorts (all respective P > 0.05). Patients who underwent a robotic approach had lower odds of conversion to laparotomy compared to the laparoscopic cohort (P < 0.0001). Laparoscopic and robotic approaches were associated with increased odds of > 12 lymph nodes examined, decreased odds of positive margins, and decreased odds of 30-day readmission, 30-day mortality, and 90-day mortality compared to the open approach. Cox-proportional hazards regression showed that both robotic and laparoscopic approaches were significantly associated with decreased mortality hazards relative to open. Both laparoscopic and robotic-assisted surgeries achieved improved oncologic outcomes and survival compared to open resection of T4 cancers. A robotic-assisted approach was significantly associated with a lower conversion rate compared to the laparoscopic approach. This case-matched study demonstrates safety of using minimally invasive techniques in T4 cancers.

Abstract
Laparoscopic low anterior rectal resection (LLAR), allowing better visualization and rectal mobilization, can reduce postoperative pain and recovery. A Contour Curved Stapler (CCS) is a very helpful device because of its curved profile that consents better access into the pelvic cavity and allows to perform rectal closure and section in one shot, especially in the presence of a narrow pelvis, complex anatomy, or large tumors. We developed an original technique of laparoscopic rectal resection using CCS. Between 2005 and 2009, in 36 cases, we performed LLAR with a three-trocar technique, starting with mobilization of left colonic flexure followed by the section of inferior mesenteric vessels. The rectum was prepared up to the levator ani with total mesorectal excision. The Lapdisc® was inserted trough a suprapubic midline incision, allowing the CCS stapler placement into the pelvic cavity. After the rectal section, the anastomosis was then performed with a circular stapler. Ileostomy was performed if neoadjuvant radiotherapy and chemotherapy have been carried out or if the anastomosis was below 4 cm from the anal verge. Mean operative time was 135 minutes and no intra- or postoperative bleeding occurred. In 27 patients we performed temporary ileostomy. In two cases we observed anastomotic leakage; one of these patients already had ileostomy. No anastomotic stenosis occurred after one-year follow-up. This procedure simplifies the section of the lower rectum, reduces leaking rate resulting from technical difficulties, and does not nullify the benefits of laparoscopy.

Abstract
The present study aimed to demonstrate the potential advantage of oral uracil-tegafur (UFUR)/leucovorin (LV) as the subsequent therapy in patients with stage III colon cancer following adjuvant LV, 5-fluorouracil and oxaliplatin (FOLFOX4) chemotherapy. Of a total 143 patients, 62 patients received only FOLFOX adjuvant chemotherapy (FOLFOX4 biweekly × 12 cycles for 6 months), and 81 patients received FOLFOXU adjuvant treatment (which consisted of FOLFOX4 biweekly × 12 cycles for 6 months followed by oral UFUR/LV for an additional 6 months). The 3-year disease-free survival (DFS) rate of the FOLFOXU group was 74.3%; which was superior to that of the FOLFOX4 group (59.9%). The average DFS time of the FOLFOXU group was superior to that of the FOLFOX4 group (P=0.003). The 5-year overall survival (OS) rate of the FOLFOXU group was 76.9%, which was also superior to that of the FOLFOX4 group (63.8%). The average OS time of patients in the FOLFOXU group was longer than that of the patients in the FOLFOX4 group (hazard ratio, 0.155; 95% confidence interval, 0.054-0.450; P=0.001). In comparison to the FOLFOX regimen, the FOLFOXU regimen achieved a more favorable response and survival time without a significant increase of toxicities in patients with stage III colon cancer as the adjuvant chemotherapy.

Abstract
The use of laparoscopy has become widespread across many surgical specialties. Its utility as treatment for colon cancer was initially met with hesitancy due to concern for port site and wound recurrences; however, this was later disproven by large retrospective series. Subsequently, there have been multiple, large, prospective, randomized studies evaluating laparoscopic versus open colectomy for colon cancer. All studies yielded similar results and showed no statistical difference in overall survival, disease-free survival, and recurrence. Additionally, these studies revealed similar operative outcomes with respect to complication rates, perioperative mortality, and conversion to open colectomy, as well as equivalent oncologic resections. Overall in the laparoscopic colectomy groups, hospital stays were shorter, and often times patients required less narcotics postoperatively, but laparoscopic operative times were longer. With adequate training, the use of laparoscopy can be safely employed for patients with colon cancer.

Abstract
AIM To determine the incidence of internal hernias after laparoscopic colorectal surgery and evaluate the risk factors and strategies in the management of this serious complication. METHOD Two databases (MEDLINE from 1946 and Embase from 1949) were searched to mid-September 2015. The search terms included volvulus or internal hernia and laparoscopic colorectal surgery or colorectal surgery or anterior resection or laparoscopic colectomy. We found 49 and 124 articles on MEDLINE and Embase, respectively, an additional 15 articles were found on reviewing the references. After removal of duplicates, 176 abstracts were reviewed, with 33 full texts reviewed and 15 eligible for qualitative synthesis. RESULTS The incidence of internal hernia after laparoscopic colorectal surgery is low (0.65%). Thirty-one patients were identified. Five cases were from two prospective studies (5/648, 0.8%), 20 cases were from seven retrospective studies (20/3165, 0.6%) and six patients were from case reports. Of the 31 identified cases, 21 were associated with left-sided resection, four with right sided resection, two with transverse colectomy, one with a subtotal colectomy and in three cases the operation was not specified. The majority of cases (64.3%) were associated with a restorative left sided resection. Nearly all cases occurred within 4 months of surgery. All patients required re-operation and reduction of the internal hernia and 35.7% of cases required a bowel resection. In 52.2% of cases, the mesenteric defect was closed at the second operation and 52.6% of cases were successfully managed laparoscopically. There were three deaths (0.08%). CONCLUSION Mesenteric hernias are a rare but important complication of laparoscopic colorectal surgery. The evidence does not support routine closure for all cases, but selective closure of the mesenteric defect during left-sided restorative procedures in high-risk patients at the initial surgery may be considered.

Abstract
Despite many years of experience with laparoscopic procedures in rectal cancer, the superiority of minimally invasive approaches has been questioned especially in recent years. This article is a short review of the current knowledge about laparoscopic approaches in comparison to conventional modalities in patients with rectal cancer. To present the current state of the knowledge, we focused on reports that were published in the last few years and compared them to multicenter trials and meta-analyses published last year. Our analysis mainly applied to the primary end-points of these trials. We also included expert opinions that have been published in the last several months.

Abstract
UNLABELLED There is a risk of dissemination of uterine malignancies during minimally invasive hysterectomies when morcellation is used. Although the technique of uterine power morcellation allows timely removal of large benign tumors through small laparoscopic incisions, there are concerns about iatrogenic spread of cancers and reduced survival for women with preoperatively unrecognized malignancies. This review examines the literature on intraperitoneal spread and implantation of mechanically disrupted malignant tissue, discusses the current diagnostic tools for preoperative assessment of uterine tumors, and summarizes the current recommendations of the Society of Gynecologic Oncologists, the American College of Obstetricians and Gynecologists, and the American Association of Gynecologic Laparoscopists. Recommendations include informed consent of the risk of disseminating an otherwise contained malignancy, appropriate preoperative evaluation for malignancy, and development of alternatives to intracorporeal morcellation. IMPLICATIONS FOR PRACTICE Preoperative assessment of uterine masses or abnormal uterine bleeding must include understanding of the limitations of an endometrial biopsy and imaging studies to evaluate the possibility of a uterine malignancy. Minimally invasive surgery using morcellation of benign uterine growths is well established and safe; however, alternative surgical techniques to morcellation must be considered when the malignant potential of a uterine mass is uncertain. Morcellation carries the risk of widespread peritoneal seeding of an unrecognized uterine malignancy. Gynecologic surgeons must weigh the unlikely occurrence of disseminating an undiagnosed uterine sarcoma with the much more common surgical risks of abdominal surgery.

Abstract
Laparoscopic techniques are gradually replacing many common surgical procedures that are performed in an increasingly aging population. Laparoscopy places different physiologic demands on the body than in open surgery. PubMed was searched for evidence related to the use of laparoscopy in the elderly population to treat common surgical pathologies. Randomized trials, systematic reviews, and meta-analyses were preferred. Currently, over 40% of all surgeries performed in the U.S. are on patients older than 65 years. By the end of the 21st century, Americans are expected to live 20 years longer than the current average. However, elderly patients clearly show higher rates of surgical morbidity and mortality overall. Laparoscopic techniques show decreased wound complications, post-operative ileus, intraoperative blood loss, and reduced need for post-operative rehabilitation. In conclusion, laparoscopic surgery is safe in the elderly population and affords multiple advantages including decreased pain and convalescence. However, the physiology of laparoscopy places demands on elderly patients that typically present with more medical comorbidities.

Abstract
OBJECTIVES To assess the risk of bias in multicenter randomized controlled trials (RCTs) investigating laparoscopic colorectal cancer surgery and review the use of quality assurance mechanisms to reduce performance bias. BACKGROUND RCTs represent the criterion standard comparison for health care interventions. For trials investigating interventional techniques, performance bias can arise through variation in delivery of the intervention. METHODS A comprehensive systematic review was undertaken using MEDLINE and EMBASE databases to identify all large RCTs investigating laparoscopic colorectal cancer surgery. Risk of performance bias was evaluated through assessment of publications and protocols to identify methods used for quality assurance of surgical technique. In addition, the Cochrane Collaboration's "risk of bias" tool was used to evaluate other potential sources of bias. RESULTS The literature search identified 48 publications, reporting upon 8 individual RCTs. All studies used mechanisms for quality assurance of laparoscopic colorectal surgery. Methods employed included credentialing of surgeons or units through assessment of experience and expertise, standardization of surgical technique, and monitoring. None report the use of structure objective assessment tools for accrediting expertise. All 8 were assessed as low risk of bias using the Cochrane tool. A framework is proposed for use as a model for quality assurance in future surgical trials. CONCLUSIONS Consideration of risk of performance bias is important when appraising trials investigating an interventional technique. Laparoscopic colorectal surgery RCTs have all employed quality assurance mechanisms to reduce risk of performance bias. Further research is indicated to investigate adopting objective assessment tools for quality assurance within multicenter RCTs.

Abstract
The advances of laparoscopic surgery since the early 1990s have caused one of the largest technical revolutions in medicine since the detection of antibiotics (1922, Flemming), the discovery of DNA structure (1953, Watson and Crick), and solid organ transplantation (1954, Murray). Perseverance through a rocky start and increased familiarity with the chop-stick surgery in conjunction with technical refinements has resulted in a rapid expansion of the indications for minimally invasive surgery. Procedure-related factors initially contributed to this success and included the improved postoperative recovery and cosmesis, fewer wound complications, lower risk for incisional hernias and for subsequent adhesion-related small bowel obstructions; the major breakthrough however came with favorable long-term outcomes data on oncological parameters. The future will have to determine the specific role of various technical approaches, define prognostic factors of success and true progress, and consider directing further innovation while potentially limiting approaches that do not add to patient outcomes.

Abstract
Colorectal cancer (CRC) is a common neoplasia in the Western countries, with considerable morbidity and mortality. Every fifth patient with CRC presents with metastatic disease, which is not curable with radical intent in roughly 80% of cases. Traditionally approached surgically, by resection of the primitive tumor or stoma, the management to incurable stage IV CRC patients has significantly changed over the last three decades and is nowadays multidisciplinary, with a pivotal role played by chemotherapy (CHT). This latter have allowed for a dramatic increase in survival, whereas the role of colonic and liver surgery is nowadays matter of debate. Although any generalization is difficult, two main situations are considered, asymptomatic (or minimally symptomatic) and severely symptomatic patients needing aggressive management, including emergency cases. In asymptomatic patients, new CHT regimens allow today long survival in selected patients, also exceeding two years. The role of colonic resection in this group has been challenged in recent years, as it is not clear whether the resection of primary CRC may imply a further increase in survival, thus justifying surgery-related morbidity/mortality in such a class of short-living patients. Secondary surgery of liver metastasis is gaining acceptance since, under new generation CHT regimens, an increasing amount of patients with distant metastasis initially considered non resectable become resectable, with a significant increase in long term survival. The management of CRC emergency patients still represents a major issue in Western countries, and is associated to high morbidity/mortality. Obstruction is traditionally approached surgically by colonic resection, stoma or internal by-pass, although nowadays CRC stenting is a feasible option. Nevertheless, CRC stent has peculiar contraindications and complications, and its long-term cost-effectiveness is questionable, especially in the light of recently increased survival. Perforation is associated with the highest mortality and remains mostly matter for surgeons, by abdominal lavage/drainage, colonic resection and/or stoma. Bleeding and other CRC-related symptoms (pain, tenesmus, etc.) may be managed by several mini-invasive approaches, including radiotherapy, laser therapy and other transanal procedures.

Abstract
BACKGROUND The objective of this study was to compare the total hospital cost of laparoscopic (lap) and open colon surgery at a publicly funded academic institution. METHODS Patients undergoing elective laparoscopic or open colon surgery for all indications at the University Health Network, Toronto, Canada, from April 2004 to March 2009 were included. Patient demographic, operative, and outcome data were reviewed retrospectively. Hospital costs were determined from the Ontario Case Costing Initiative, adjusted for inflation, and compared using the Mann-Whitney U test. Linear regression was used to analyze the relationship between length of stay and total hospital cost. RESULTS There were 391 elective colon resections (223 lap/168 open, 15.4 % conversion). There was no difference in median age, gender, or Charlson score. Body mass index was slightly higher for laparoscopic surgery (27.5/25.9 lap/open; p = 0.008), while the American Society of Anesthesiologists score was slightly higher for open surgery. Median operative time was greater for laparoscopic surgery (224/196 min, lap/open; p = 0.001). There was no difference in complication rates (21.6/22.5 % lap/open; p = 0.900), reoperations (5.8/6.5 % lap/open; p = 0.833) or 30-day readmissions (7.6/12.5 % lap/open; p = 0.122). Number of emergency room visits was greater with open surgery (12.6/20.8 % lap/open; p = 0.037). Operative cost was higher for laparoscopic surgery ($4,171.37/3,489.29 lap/open; p = 0.001), while total hospital cost was significantly reduced ($9,600.22/12,721.41 lap/open; p = 0.001). Median length of stay was shorter for laparoscopic surgery (5/7 days lap/open; p = 0.000), and this correlated directly with hospital cost. CONCLUSIONS Laparoscopic colon surgery is associated with increased operative costs but significantly lower total hospital costs. The cost savings is related, in part, to reduced length of stay with laparoscopic surgery.

Abstract
Purpose Laparoscopy-assisted colectomy (LAC) has gained acceptance for the treatment of colorectal cancer. However, conventional palpation of the liver and adequate observation of the abdominal cavity are not achievable during LAC. The aim of this study was to assess the clinical value of using Sonazoid (contrast enhanced)-intraoperative laparoscopic ultrasonography (S-IOLUS) in patients with primary colorectal cancer. Methods From May 2005 to August 2008, 454 patients underwent 339 LACs and 115 open colectomies for colorectal cancer. One hundred forty-eight patients with clinical stage II or III colorectal cancer, as determined by preoperative imaging, who were undergoing LACs were prospectively enrolled. Results Although IOLUS did not detect any lesions, small hypoechoic lesions were detected by the S-IOLUS (n = 71) in the Kupffer-phase view of two patients (2.8 %). None of the 71 patients who underwent S-IOLUS showed liver metastases within 6 months after LAC. In the conventional IOLUS group (n = 77), metastatic lesions were identified in two patients (2.6 %). The new liver metastases in these two patients were detected within 6 months after LAC. Conclusions S-IOLUS of the liver during colorectal cancer surgery is useful for staging and as a diagnostic modality. It can identify lesions that are undetectable by preoperative imaging, and may be considered for routine use during LAC.

Abstract
Laparoscopic colectomy has been reported as an alternative for treatment of colorectal cancer. However, its long-term efficacy and safety remain obscure. The purpose here was to review our experience with laparoscopic colectomy in 899 patients between June 2001 and December 2008. Of them, 43 patients were converted to open surgery and 846 accepted laparoscopic colorectomy successfully. Among these 846 patients, 790 patients underwent radical resection and 56 patients underwent palliative resection. Only 1 patient died from perioperative pulmonary infection; thus the mortality was 0.12% (1/846). The morbidity of perioperative complications was 18.20% (154/846): intraoperative complication rate was 4.49% (38/846) and the most common intraoperative complication was subcutaneous emphysema and hypercapnia (1.65%, 14/846); postoperative complication rate was 13.71% (116/846) and the most common postoperative complication was ileus (4.37%, 37/846). The overall followed-up rate was 86.41% (731/846, 680 for radical operations and 51 palliative operations). Postoperative deaths happened to 139 patients, including 112 after radical operation and 27 after palliative resection. Of these 112 patients, 97 deaths were cancer-related (14.26%, 97/680) and 15 deaths were non-cancer-related. There were 10 patients encountered local recurrence (1.47%, 10/680) and 105 for metastasis (15.44%, 105/680) after radical operation. Forty-two patients are still alive with tumor. Overall survival rate was 80.98% (592/731), 3-year disease-free survival (DFS) rate after radical operation was 78.0%, and 3-year DFS rate after radical operation for stage I, stage II, and stage III was 89.0%, 85.0%, and 65.0%, respectively. In conclusion, laparoscopic colorectal resection is a feasible and safe technology for colorectal cancer.

Abstract
BACKGROUND The use of laparoscopy to perform lower anterior rectal resection is increasing worldwide because it allows better visualisation and rectal mobilisation and also reduces postoperative pain and recovery. The Contour Curved Stapler (CCS) is a very helpful device because of its curved profile that enables better access into the pelvic cavity and allows rectal closure and section to be performed in one shot. In this paper, we present an original technique to use this device, made for open surgery, in laparoscopy and the results of our experience. METHODS We retrospectively evaluated the data of all patients who underwent lower laparoscopic anterior rectal resection and in which the CCS was used to perform section of the rectum between September 2005 and September 2011. To perform section of the rectum a Lapdisc(®) was inserted through a 6-7 cm supra-pubic midline incision to allow placement of the CCS into the pelvic cavity. Patients' biographical and surgical data such as sex, age, indication for surgery, infection, anastomotic leakage or stenosis and staple-line bleeding were prospectively collected in a computerised database and evaluated. RESULTS Between September 2005 and September 2011, we performed 45 laparoscopic lower rectal resection using CCS, 27 male and 18 female with a mean age of 61 years (range 40-82 years) and a mean body mass index (BMI) of 26.5 kg/m(2) (range 16.5-35 kg/m(2)). In 29 cases a temporary ileostomy was performed. Mean operative time was 131 min (range 97-210 min). In all cases it was possible to perform a lower section of the rectum with CCS. No intraoperative or postoperative staple line bleeding occurred. In two patients we observed anastomotic leaks and in one of these a temporary ileostomy was performed. None of the patients showed an anastomotic stenosis at 1-year follow-up colonoscopy. CONCLUSIONS This study shows that CCS enables section of the lower rectum to be easily performed, especially in adverse anatomical condition, and the technique proposed by us allows the use of this stapler without giving up the benefits of laparoscopic access.

Abstract
BACKGROUND Specific International Classification of Diseases, Ninth Revision, codes for laparoscopic procedures introduced in 2008 allow a more accurate evaluation of laparoscopic colorectal surgery. METHODS Using the Nationwide Inpatient Sample 2009, a retrospective analysis of surgical colorectal cancer and diverticulitis patients was conducted. Logistic regression was used to estimate odds ratios comparing the outcomes of laparoscopic, open, and converted surgery. RESULTS A total of 121,910 patients underwent resection for cancer and diverticulitis, 35.41% of whom underwent laparoscopic surgery. Compared with open surgery, laparoscopic surgery had lower postoperative complication rates, lower mortality, shorter hospital stays, and lower costs. Compared to open surgery, laparoscopic surgery independently decreased mortality, postoperative anastomotic leak, urinary tract infection, ileus or obstruction, pneumonia, respiratory failure, and wound infection. Converted surgery was independently associated with anastomotic leak, wound infection, ileus or obstruction, and urinary tract infection. CONCLUSIONS Laparoscopic colorectal surgery has lower postoperative complications, lower mortality, lower costs, and shorter hospital stays. Conversion had higher complications compared with laparoscopy. The use of laparoscopy should increase with efforts to minimize conversion.

Abstract
Postoperative adjuvant chemoradiotherapy was recommended as the standard treatment for patients with rectal cancer because it reduces local recurrence. This paradigm shifted with the use of neoadjuvant chemoradiotherapy, which not only reduces local recurrence but also improves sphincter preservation and surgical outcomes. However, the treatment of rectal carcinoma remains complicated. The accuracy of tumor staging can be compromised depending on the imaging modality used. The addition of modern chemotherapeutics and biologics to 5-fluorouracil as radiation sensitizers is questionable. Oxaliplatin as a radiation sensitizer has minimal effects on the pathologic complete response, but improves the radiographical response at the expense of an increased risk of toxicities. The role of biologics in addition to radiation therapy continues to be explored. Attention has focused on improving diagnostic imaging, radiation oncology, and surgical techniques, treatment regimens, and on exploring a role of molecular markers for patients with rectal cancers. We review the pivotal trials that have led to the current treatment paradigm for locally advanced rectal cancer and discuss novel methodologies that are being developed for the treatment of this prevalent malignancy.

Abstract
BACKGROUND Real-world cost analysis of elective laparoscopic versus open colon resection in a tertiary Canadian teaching hospital was performed to evaluate the financial impact of minimally invasive surgery with the appointment of an experienced laparoscopic surgeon in a single-payer system. METHODS A retrospective review of elective laparoscopic and open segmental colectomies (2005-2010) was performed. Combined cases and procedures performed for inpatients were excluded to minimize cost variation. The hospital case-costing system was used to calculate the hourly cost of operating room time and the daily hospital ward stay. The cost of disposable equipment was calculated manually. A cost-minimization analysis was performed from the hospital perspective, which excludes physician payment. Cases were analyzed on an intention-to-treat basis. RESULTS For this study, 470 right-side colectomies (322 open and 148 laparoscopic) and 266 left-side colectomies (181 open and 85 laparoscopic) were found to match the inclusion criteria. The operating room time was longer for the laparoscopic procedures than for the open procedures: 203.4 versus 173.4 min (P = 0.1) for right and extended right hemicolectomy (RC) and 287.4 versus 173.4 min (P = 0.009) for left and sigmoid colectomy (LC). This resulted in higher operating room costs: $4,094.10 versus $3312.11 for RC and $5,784.88 versus $4,582.55 for LC. The median hospital stay for an index admission was shorter for both sides: 5 days versus 8 days (P = 0.01) for RC and 4 days versus 6 days (P = 0.04). This resulted in lower ward costs: $4,556.07 versus $6,632.82 for RC and $3,297.24 versus $5,949.09 for LC. The cost of care per index admission after laparoscopic versus open resection was $10,097.93 versus $10,444.69 for RC and $11,067.72 versus. $11,146.56 for LC. The introduction of laparoscopic surgery has saved our institution $58,021.43 over 5 years. CONCLUSION The reasons for observed differences in operating room time and length of hospital stay were uncontrolled and may be multifactorial. However, the results demonstrate that adopting a laparoscopic approach for elective colon surgery resulted in progressive financial savings.

Abstract
Purpose The long-term results of a laparoscopic resection for colorectal cancer have been reported in several studies, but reports on the results of laparoscopic surgery for rectal cancer are limited. We investigated the long-term outcomes, including the five-year overall survival, disease-free survival and recurrence rate, after a laparoscopic resection for colorectal cancer. Methods Using prospectively collected data on 303 patients with colorectal cancer who underwent a laparoscopic resection between January 2001, and December 2003, we analyzed sex, age, stage, complications, hospital stay, mean operation time and blood loss. The overall survival rate, disease-free survival rate and recurrence rate were investigated for 271 patients who could be followed for more than three years. Results Tumor-node-metastasis (TNM) stage I cancer was present in 55 patients (18.1%), stage II in 116 patients (38.3%), stage III in 110 patients (36.3%), and stage IV in 22 patients (7.3%). The mean operative time was 200 minutes (range, 100 to 535 minutes), and the mean blood loss was 97 mL (range, 20 to 1,200 mL). The mean hospital stay was 11 days and the mean follow-up period was 54 months. The mean numbers of resected lymph nodes were 26 and 21 in the colon and the rectum, respectively, and the mean distal margins were 10 and 3 cm. The overall morbidity rate was 26.1%. The local recurrence rates were 2.2% and 4.4% in the colon and the rectum, respectively, and the distant recurrence rates were 7.8% and 22.5%. The five-year overall survival rates were 86.1% in the colon (stage I, 100%; stage II, 97.6%; stage III, 77.5%; stage IV, 16.7%) and 68.8% in the rectum (stage I, 90.2%; stage II, 84.0%; stage III, 57.6; stage IV, 13.3%). The five-year disease-free survival rates were 89.8% in the colon (stage I, 100%; stage II, 97.7%; stage III, 74.2%) and 74.5% in the rectum (stage I, 90.0%; stage II, 83.9%; stage III, 59.2%). Conclusion Laparoscopic surgery for colorectal cancer is a good alternative method to open surgery with tolerable oncologic long-term results.

A role of 18F-fluorodeoxyglucose positron emission/computed tomography in a strategy for abdominal wall metastasis of colorectal mucinous adenocarcinoma developed after laparoscopic surgery. World J Surg Oncol 2011; 9:28.

Abstract
Metastasis to the abdominal wall including port sites after laparoscopic surgery for colorectal cancer is rare. Resection of metastatic lesions may lead to greater survival benefit if the abdominal wall metastasis is the only manifestation of recurrent disease. A 57-year-old man, who underwent laparoscopic surgery for advanced mucinous adenocarcinoma of the cecum 6 years prior, developed a nodule in the surgical wound at the lower right abdomen. Although tumor markers were within normal limits, the metastasis to the abdominal wall and abdominal cavity from the previous cecal cancer was suspected. An abdominal computed tomography scan did not provide detective evidence of metastasis. 18F-fluorodeoxyglucose positron emission/computed tomography (18F-FDG PET/CT) was therefore performed, which demonstrated increased 18F-fluorodeoxyglucose uptake (maximum standardized uptake value: 3.1) in the small abdominal wall nodule alone. Histopathological examination of the resected nodule confirmed the diagnosis of metastatic mucinous adenocarcinoma. Prognosis of intestinal mucinous adenocarcinoma is reported to be poorer than that of non-mucinous adenocarcinoma. In conclusion, this case suggests an important role of 18F-FDG PET/CT in early diagnosis and decision-making regarding therapy for recurrent disease in cases where a firm diagnosis of recurrent colorectal cancer is difficult to make.

Abstract
BACKGROUND Minimally invasive surgery (MIS) for colorectal resection has been shown to improve short-term outcomes compared with open surgery in patients with colorectal cancer. Currently, there is a paucity of data demonstrating similar efficacy between MIS and open colorectal resection in the elderly population. We hypothesized that minimally invasive surgery provides improved short-term outcomes in elderly patients with colorectal cancer. METHODS A review of 242 consecutive elderly (≥ 65 y of age) patients who underwent either open or MIS colorectal resection for adenocarcinoma at one institution was conducted. Short-term and oncologic outcomes were analyzed. Continuous variables were analyzed by the Mann-Whitney U test. Categorical variables were compared by χ(2) tests. Survival was compared by the Kaplan-Meier method using the log rank test for comparison. RESULTS Of the 242 elderly patients with colorectal cancer (median American Society of Anesthesiology score (ASA) scores of 3), 80% (n = 195) of patients underwent open and 20% (n = 47) had MIS colorectal cancer resections. Patients undergoing MIS had a faster return of bowel function, decreased days to nasogastric tube removal, decreased days to flatus and bowel movement, and quicker advancement to clear liquid and regular diets. The overall length of hospital stay in the MIS group was decreased by 40% as well as a trend towards a 50% decrease in SICU stay. Additionally, there was 66% decrease in cardiac complications in the MIS group. When evaluating for oncologic adequacy as measured by number of lymph nodes and surgical resection margins, MIS surgery offered equivalent results as open resection. Furthermore, there was no significant difference in overall survival for MIS versus open colorectal surgery. CONCLUSION Minimally invasive colorectal cancer resection leads to improved short-term outcomes as demonstrated by decreased length of hospital stay and faster return of bowel function. Additionally, there appears to be no difference in oncologic outcomes in the elderly. On the basis of our data, age alone should not be a contra-indication to laparoscopic colorectal cancer resection.

Abstract
As a result of the obvious benefits of laparoscopic cholecystectomy, minimally invasive techniques have been applied to more complex gastrointestinal procedures, including colorectal resections. The goal in adapting laparoscopic techniques for colorectal surgery is to offer an operation that results in less pain, shorter hospital stay, more rapid return to normal activities, and improved cosmesis compared with conventional operation. The challenge has been to show that this can be done safely and efficiently and that for cancer patients there is no detrimental oncologic effect. The major issues that have been and continue to be addressed are (1) whether an adequate resection can be performed laparoscopically, (2) whether there is a high rate of wound or port site recurrence following these operations, and (3) whether, by using these techniques, we are trading short-term benefits for a poor long-term oncologic outcome. To answer these fundamental questions, several prospective randomized trials have been conducted and several more are under way. The results of these trials indicate that, in terms of cancer outcome, there is no difference in overall survival, disease-free survival, and wound recurrences in patients treated using laparoscopic techniques compared with conventional operation. In addition, there are short-term benefits associated with the use of these techniques. It can now be said that from an oncologic standpoint, in experienced hands, laparoscopic colectomy for curable colon cancer is equivalent to conventional therapy, and it is superior to conventional operation regarding short-term outcomes. Laparoscopic colectomy for colon cancer should be offered to appropriately selected patients.

Abstract
The author presents a historical overview of cancer surgery of the last century. At the last quarter of the century the main characteristic of this process has been the significant extension of surgical radicality. Three new surgical methods appeared and have been routinely used at the Surgical Clinic of the Szeged University School, to increase surgical radicality, to improve survival rate without impairing the postoperative quality of life. 1.) Subtotal colectomy (STC) involves an extended resection of the colon over the splenic flexure. In a period of 8 years a total of 72 STCs were performed for the treatment of large bowel obstructions or symptomatic stenosis caused by cancer of the left colon. STC offers: a) one stage treatment for colonic obstruction in emergency surgery, b.) removal of the tumor with sufficient oncological radicality, c.) primary reconstruction of the digestive tract, with a safe ileocolic anastomosis even in emergency cases. Based on a study about postoperative quality of life of STC operated patients, it proved to be normal. 2.) The author reports a total of 108 middle and low third rectal cancer cases operated on by total mesorectal excision (TME) by the method of Heald. The oncological basis of this procedure is the horizontal regional metastatization of rectal cancer. The author succeeded in 60% of cases to perform an anterior resection with preservation of the anal sphincter, and to decrease the early (within two years after surgery) local recurrence rate from 14.5% to 6.4%, compared to the group of patients operated on by traditional technic. 3.) A total of 154 patients with locally advanced - stage IV - colorectal cancer underwent extended surgery of multivisceral resections as a treatment of cancer process involving adjacent abdominal organs. Surgery was performed to treat advanced cancer of the colon in 112 cases and the one of the rectum in 42 cases. The mortality rate was 7% in the colon cancer group, and 12% in the group of rectal cancer patients. In their tumor-free postoperative period 90% of colon cancer patients and 95% of rectal cancer patients had an improved quality of life. The 5 years survival rate was 40% in the colon group and 22% in the rectal cancer group. In the group of patients having more than 3 simultaneously tumorous organs, in spite of the multiple organ resections, no 5 years survival has been recorded.

Abstract
OBJECTIVE There are a limited number of studies describing the role of minimally invasive colectomy for urgent or emergent conditions of the large bowel. We hypothesize that laparoscopic colectomy in urgent and emergent setting can be performed safely in select settings. METHOD A cohort of patients treated at a single institution from 2001 to 2006 was identified from a prospective database. Patients who underwent open or minimally invasive surgery (MIS), including laparoscopic (LAP) or hand-assisted laparoscopic surgery (HALS) colectomy for urgent and emergent conditions were included. RESULTS A total of 68 [open 32, MIS 36 [HALS 22, LAP 14)] patients underwent urgent or emergent colectomy on our colorectal service during the 5-year time period. Patients with toxic colitis were more often selected for MIS. Patients with colon perforation or large bowel obstruction were more often selected for open surgery. The MIS group had a lower body mass index (BMI), lower American Society of Anesthesiologists fitness grade and was more likely to have been immunosuppressed. There was no difference in patient morbidity between the open and MIS groups. The MIS group had a longer median operative time and fewer cases of prolonged hospitalization. CONCLUSION We conclude that minimally invasive colectomy by experienced surgeons appears to be safe and effective for appropriately selected patients with emergent and urgent conditions of the large bowel.

Abstract
Colorectal anastomotic leak remains one of the most feared post-operative complications, particularly after anterior resection of the rectum with, the shift from abdomino-peritoneal resections to total mesorectal excision and primary anastomosis. The literature fails to demonstrate superiority of stapled over hand-sewn techniques in colorectal anastomosis, regardless of the level of anastomosis, although a high stricture rate was noted in the former technique. Thus, improvements in safety aspects of anastomosis and alternatives to hand-sewn and stapled techniques are being sought. Here, we review alternative anastomotic techniques used to fashion bowel anastomosis. Compression anastomosis using compression anastomotic clips, endoluminal compression anastomotic rings, AKA-2, biofragmental anastomotic rings, or Magnamosis all involve the concept of creating a sutureless end-to-end anastomosis by compressing two bowel ends together, leading to a simultaneous necrosis and healing process that joins the two lumens. Staple line reinforcement is a new approach that reduce the drawbacks of staplers used in colorectal practice, i.e. leakage, bleeding, misfiring, and inadequate tissue approximation. Various non-absorbable, semi or fully absorbable materials are now available. Two other techniques can provide alternative anastomotic support to the suture line: a colorectal drain and a polyester stent, which can be utilized in ultra-low rectal excision and can negate the formation of a defunctioning stoma. Doxycycline coated sutures have been used to overcome the post-operative weakness in anastomosis secondary to rapid matrix degradation mediated by matrix metalloproteinase. Another novel technique, the electric welding system, showed promising results in construction of a safe, neat, smooth sutureless bowel anastomosis. Various anastomotic techniques have been shown to be comparable to the standard techniques of suturing and stapling. However, most of these alternatives need to be accepted and optimized for future use.

Abstract
AIMS A prospective clinical audit of all patients undergoing laparoscopic surgery with the intention of primary colonic left-sided intracorporeal stapled anastomosis to identify the rate of anastomotic leaks on an intention to treat basis with or without defunctioning stoma. MATERIALS AND METHODS All patients undergoing laparoscopic colorectal surgery resulting in left-sided stapled anastomosis were included with no selection criteria applied. All operations were conducted by the same surgical team and the same preparation and intraoperative methods were used. The factors analyzed for this audit were patient demographics (age and sex), indication for operation, procedure performed, height of anastomosis, leak rate and the outcome, inpatient stay, mortality, rate of defunctioning stomas, and rate of conversion to open procedure. Results for anastomotic leakage were compared with known results from the Wessex Colorectal Audit for open colorectal surgery. RESULTS A total of 69 patients (43 females, 26 males; median age 69 years, range 19 - 86 years) underwent colonic procedures with left-sided intracorporeal stapled anastomoses. Of these, 14 patients underwent reversal of Hartmann's, 42 - Anterior Resection, 11 - Sigmoid Colectomy, 2 - Left Hemicolectomy. Excluding reversals of Hartmann's, 29 operations were performed for malignant and 26 for benign disease. Five patients were defunctioned, and 3 were subsequently reversed. The median height of anastomosis was 12 cm, range 4 - 18 cm from anal verge as measured either intra-operatively, or by rigid sigmoidoscopy post-operatively. Four cases were converted to open surgery. There was 1 post-operative death within 30 days. There was 1 anastomotic leak (the patient that died), and 1 patient developed a colo-vesical fistula. Median post-operative stay was 7 days, range 2-19. CONCLUSION This clinical audit confirms that the anastomotic leak rate for left-sided colorectal stapled anastomosis is no worse than that for open surgery. Therefore the decision making process for defunctioning stoma should be guided by the same principles as open surgery.

Abstract
BACKGROUND The role of laparoscopic surgery in the management of stage IV colorectal cancer remains uncertain. METHODS Sixty-five patients with stage IV disease from among 578 colorectal cancer patients who underwent laparoscopic surgery since 2001 were compared with 513 patients who had stage 0-III disease. The criteria for excluding stage IV patients from laparoscopic surgery were huge tumors, low rectal cancer, massive ascites due to peritoneal seeding, bowel perforation and/or obstruction, and poor general condition and/or cachexia. Data were analyzed by chi-square test or Student's t-test, with P < 0.05 being considered significant. RESULTS The two groups of patients had similar demographic features. The open conversion rate was 4.6% (3/65 patients) in the stage IV group and 2.7% (14/513 patients) in the stage 0-III group, and the difference between the groups was not significant. In the stage IV group, depth of tumor invasion and tumor diameter were both significantly greater than in the stage 0-III group. However, operating time and blood loss were similar in the two groups (stage IV: 189.0 min and 95.0 g; stage 0-III: 182.5 min and 60.0 g), although blood loss was significantly greater in the stage IV group when patients undergoing rectal surgery were compared. The incidence of postoperative complications and the postoperative course of the two groups were similar. CONCLUSIONS Despite their larger and more invasive tumors, the short-term outcome of laparoscopic surgery in patients with stage IV colorectal cancer was similar to that for stage 0-III patients. This result indicates that laparoscopic surgery can be successfully performed in selected stage IV colorectal cancer patients.

Abstract
INTRODUCTION Laparoscopic surgery in the treatment of diverticular disease offers multiple benefits compared with its open surgery counterpart. There are two distinct techniques, the laparoscopically assisted and the laparoscopic hand assisted approach. The purpose of this study is to demonstrate that the hand assisted approach can be used if, during a laparoscopically assisted approach, there is difficulty in dissection and/or exposure, and before performing a laparotomy. MATERIAL AND METHODS This study is a retrospective cohort series that was performed in a private tertiary hospital in Mexico City. Patients with the diagnosis of diverticular disease who underwent a laparoscopically assisted sigmoidectomy were selected. These included patients who, during their procedure required conversion to a hand assisted approach. RESULTS A total of 47 sigmoid colectomies began with assisted laparoscopy, of which 33 were completed, 4 required laparotomy, and 10 where completed using hand assistance (none required laparotomy). There were no statistically significant differences in return of bowel function (P=0.879) and postoperative hospital stay (P=0.679) between the group that was completed by assisted laparoscopy vs. hand assisted. CONCLUSIONS If there is difficulty in exposure or dissection during a laparoscopically assisted sigmoid colectomy, the hand assisted approach is an alternative before the laparotomy.

Abstract
OBJECTIVE The aim of this study is to compare technical feasibility and oncologic efficacy of totally laparoscopic versus open subtotal gastrectomy for gastric adenocarcinoma. BACKGROUND Laparoscopic gastrectomy for adenocarcinoma is emerging in the West as a technique that may offer benefits for patients, although large-scale studies are lacking. METHODS This study was designed as a case-controlled study from a prospective gastric cancer database. Thirty consecutive patients undergoing laparoscopic subtotal gastrectomy for adenocarcinoma were compared with 30 patients undergoing open subtotal gastrectomy. Controls were matched for stage, age, and gender via a statistically generated selection of all gastrectomies performed during the same period of time. Patient demographics, tumor-node-metastasis (TNM) stage, histologic features, location of tumor, lymph node retrieval, recurrence, margins, and early and late postoperative complications were compared. RESULTS Tumor location and histology were similar between the two groups. Median operative time for the laparoscopic approach was 270 min (range 150-485 min) compared with median of 126 min (range 85-205 min) in the open group (p < 0.01). Hospital length of stay after laparoscopic gastrectomy was 5 days (range 2-26 days), compared with 7 days (range 5-30 days) in the open group (p = 0.01). Postoperative pain, as measured by number of days of IV narcotic use, was significantly lower for laparoscopic patients, with a median of 3 days (range 0-11 days) compared with 4 days (range 1-13 days) in the open group (p < 0.01). Postoperative early complications trended towards a decrease for laparoscopic versus open surgery patients (p = 0.07); however, there were significantly more late complications for the open group (p = 0.03). Short-term recurrence-free survival and margin status was similar between the two groups (p = not significant) with adequate lymph node retrieval in both groups. CONCLUSIONS Laparoscopic subtotal gastrectomy for adenocarcinoma is comparable to the open approach with regard to oncologic principles of resection, with equivalent margin status and adequate lymph node retrieval, demonstrating technically feasibility and equivalent short-term recurrence-free survival. Additional benefits of decreased postoperative complications, decreased length of hospital stay, and decreased narcotic use make this a preferable approach for selected patients.

MÉTODOS: Analisamos retrospectivamente entre novembro de 1995 e outubro de 2006, 120 pacientes submetidos à ressecções laparoscópicas de cólon. A indicação cirúrgica incluiu 65 pacientes com neoplasia, 50 com doença diverticular dos cólons, três com constipação intestinal crônica intensa, um com Doença de Crohn e um com tuberculose intestinal. Todos os pacientes foram operados eletivamente e analisados quanto ao resultado cirúrgico e suas complicações, número de conversões, reoperações, morbi-mortalidade e tempo de internação hospitalar. RESULTADOS: As complicações intra-operatórias totalizaram 4% (5/120) dos casos. A taxa de conversão foi de 9% (11/120). Reoperação foi necessária em 6% (7/120) dos pacientes. A deiscência de anastomose ocorreu em 6,5% dos casos (8/120) e a mortalidade geral foi de 2,5% (3/120). O tempo médio de internação foi de 8,2 dias. CONCLUSÃO: A colectomia laparoscópica apresenta taxas aceitáveis de complicação e conversão para cirurgia aberta. Além das vantagens da laparoscopia em diminuir a dor pós-operatória e melhorar o resultado estético, destacam-se o retorno precoce da função intestinal e um número menor de infecções de sítio operatório.

Ann Surg Oncol 2009; 16:1279-86. [PMID: 19252948 DOI: 10.1245/s10434-009-0398-4] [Citation(s) in RCA: 111] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2008] [Revised: 02/05/2009] [Accepted: 02/05/2009] [Indexed: 12/21/2022]
Abstract
BACKGROUND Laparoscopic rectal resection (LRR) is an oncologically safe procedure. The impact of conversion to open surgery on outcomes has not been fully elucidated. The aim of the study is to compare short- and long-term outcomes of converted (CR) and not converted (NCR) patients undergoing LRR. METHODS Data were drawn from a prospective database of LRR performed between 1999 and 2008. Statistical analysis employed the chi-squared or Wilcoxon test and Kaplan-Meier estimation. RESULTS Of 173 patients undergoing LRR, 26 (15%) required conversion. No differences in age, gender, American Society of Anesthesiologists (ASA) score, and T and N stages were observed between CR and NCR patients. Conversion was associated with higher body mass index (BMI) (27.3 versus 24.9 kg/m(2), P < 0.001) and American Joint Committee on Cancer (AJCC) stage IV (26.9% versus 4.8%, P < 0.001), and resulted in longer operative time (342 versus 285 min, P = 0.006) and increased intraoperative complication rate (31% versus 5%, P < 0.001). No differences were observed in postoperative outcome between CR and NCR patients. After a mean follow-up of 46 and 36 months, 5-year disease-free survival was 55.7% in CR group and 79.2% in NCR group (P = 0.007). After exclusion of stage IV patients from the analysis, 5-year disease-free survival was 71.1% in CR group and 85.3% in NCR group (P = 0.17), while the overall recurrence rate was 26.3% in CR patients and 11.4% in NCR patients (P = 0.07). CONCLUSIONS Our study suggests that conversion to open surgery does not affect postoperative outcome, but could have a negative impact on long-term overall recurrence rate. LRR should be performed by experienced surgeons in selected patients.

Abstract
UNLABELLED Although laparoscopic surgery for colorectal cancer improves post operative recovery, its use for curative treatment especially for rectal cancer is still controversial. The present study is an attempt to analyze the results of the safety and feasibility of laparoscopic surgery including short-term results for rectal cancer. METHODS This study accumulated 109 patients with rectal cancer retrospectively who underwent laparoscopic surgery. Patients with rectosigmoid colon cancer were excluded from this study. Patients' data, perioperative data including morbidity and mortality, surgical data were analyzed, and the 3-year disease-free survival data were calculated by Kaplan-Meier method, according to the location of the tumor and the UICC stage. RESULTS There were 71 males and 38 females who underwent laparoscopic surgery for rectal cancer. Mean age of them was 63.7+/-12.5 years. The mean BMI was 22.6+/-2.8 kg/m(2). The operative procedure was low anterior resection (LAR) in 80 cases, abdominoperineal resection (APR) in 14 cases, intersphincteric resection (ISR) in 14 cases, and Hartmann's procedure in 1 case. The operation time was 237.0+/-71.6 minutes. Blood loss was 165.0+/-163.8. The postoperative morbidity was 22.9%. The postoperative mortality within 30 days after surgery was not experienced. The 3-year disease-free survival rate was 94.2% after curative surgery. According to the UICC stage, the 3-year disease survival rate was 100% in stage 0/I, 89.1% in stage II, and 84.6% in stage III. CONCLUSIONS Laparoscopic surgery for rectal cancer was safe and feasible including postoperative morbidity, mortality and postoperative short-term results. Further study is necessary to clarify the quality of laparoscopic surgery including the postoperative long-term results.

Abstract
OBJECTIVE To test the hypothesis that surgeon volume would not predict short- and long-term outcomes when evaluated in the setting of technical credentialing. SUMMARY BACKGROUND DATA Surgical volume is a known predictor of outcomes; the importance of technical credentialing has not been evaluated. METHODS Fifty-three credentialed surgeons operated on 871 patients in the Clinical Outcomes of Surgical Therapy Study (NCT00002575), investigating laparoscopic versus open surgery for colon cancer. Credentialing required that each surgeon document performance of at least 20 laparoscopic colon cases and demonstrate oncologic techniques on a video-recorded case. Surgeons were separated based on volume entered into the trial (low, < or =5 cases (n = 39); medium, 6-10 cases (n = 9); or high, >10 cases (n = 5)) and compared by outcomes. RESULTS Patients treated by high volume compared with medium or low volume surgeons were older (70, 66, and 68 years; P < 0.001), more often had right-sided tumors (63%, 46%, and 53%; P < 0.001) and had more previous operations (48%, 38% and 45%; P < 0.004), respectively. Mean operative times were shorter (123, 147 and 145 minutes; P < 0.001), distal margins longer (13.4, 12.4 and 11.6 cm; P = 0.005), and lymph node harvest greater (14.8, 12.8, 12.6; P = 0.05) for high versus medium versus low volume surgeons. However, rates of conversion, complications, 5-year survival, and disease-free survival showed no significant differences. CONCLUSION When tested in a randomized controlled trial with case-specific surgical technical credentialing and auditing, surgeon volume did not predict differences in rates of conversion, complications, or long-term cancer outcomes. Case-specific technical credentialing should be further studied specific to the role it could play in creating consistent, high quality outcomes.

Abstract
BACKGROUND Iatrogenic perforation of the colon during elective colonoscopy is a rare but serious complication. Treatment using laparoscopic methods is a novel approach, only described in the recent literature. We hypothesized that laparoscopic treatment of iatrogenic colon perforation would result in equal therapeutic efficacy, less perioperative morbidity, smaller incisions and decreased length of stay, and an overall better short-term outcome compared to open methods. METHODS We reviewed our prospectively collected patient database from July 2001 to July 2005 and compared the intraoperative data and postoperative outcomes of patients who underwent laparoscopic primary repair versus those who had open primary repairs of iatrogenically perforated large bowel. RESULTS The laparoscopic (mean age 70 years; range 20-91 years; 18 percent male) and open (mean age 68 years; range 36-87 years; 43 percent male) groups were similar with regard to age. Overall, patients who underwent laparoscopic (n = 11) versus open (n = 7) repair had comparable operative (OR) times (mean 104 minutes, range 60-150 minutes versus mean 98 minutes, range 40-130 minutes, p = 0.04), shorter length of stay [LOS, (5.1 +/- 1.7 days versus 9.2 +/- 3.1 days, p = 0.01)], fewer complications (two versus five, p = 0.02) and shorter incision length (16 +/- 14.7 mm versus 163 +/- 54.4 mm, p = 0.001). CONCLUSIONS A laparoscopic approach to iatrogenic colon perforation results in decreased morbidity, decreased length of stay, and a shorter incision length compared to an open method. In those cases where it is feasible and the surgical skills exist, a laparoscopic attempt at colon repair should probably be the initial clinical approach.
