Abstract
Background There are numerous indications for minimally invasive surgery. However, the laparoscopic approach for extended pelvic surgery is currently provided by only a few institutions specializing in cancer treatment, primarily because of technical difficulties that arise in cases involving a narrow pelvis and rigid forceps. We report a case of robot-assisted total pelvic exenteration for rectal cancer involving the prostate. We assessed the feasibility of robot-assisted total pelvic exenteration and compared the short-term outcomes of other conventional and minimally invasive approaches. Case presentation A 67-year-old man was referred to our hospital after positive fecal blood test results. The initial diagnosis was clinical T4bN2aM0, Stage IIIC rectal cancer involving the prostate. The patient underwent neoadjuvant chemoradiotherapy. Consequently, robot-assisted total pelvic exenteration with an ileal conduit and end colostomy creation were performed. The total operative duration was 9 h and 20 min. The durations of robot console usage by the colorectal and urological teams were 2 h 9 min and 2 h 23 min, respectively. The patient was discharged on postoperative day 21. The pathological diagnosis was T4b (prostate) N0M0, Stage IIC. The resection margin was 2.5 mm. During reassessment at 2 years after resection, no evidence of recurrence was observed. Conclusions Robot-assisted total pelvic exenteration was performed for a patient with advanced rectal cancer without serious complications. Robot-assisted total pelvic exenteration may provide the advantages of minimally invasive surgery, particularly in the enclosed space of the pelvis.

Comparison of textbook versus three-dimensional animation versus cadaveric training videos in teaching laparoscopic rectal surgery: a prospective randomized trial. Colorectal Dis 2022; 24:1007-1014. [PMID: 35297178 DOI: 10.1111/codi.16119] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2021] [Revised: 01/23/2022] [Accepted: 02/14/2022] [Indexed: 12/12/2022]
Abstract
AIM The aim of this prospective randomized study was to compare the effectiveness of various educational tools in laparoscopic rectal surgery, including surgical textbooks, animation and cadaveric videos. METHOD Initially, an electronic assessment test assessing knowledge of laparoscopic rectal surgery was created and validated. The test was sent to graduates completing a general surgery residency programme in Turkey, who were then randomized into four groups based on the type of study material. After a 4 week study period, the volunteers were asked to answer the same electronic assessment test imported into an edited live laparoscopic rectal surgery video. Pre- and posteducation assessment tests among the groups were compared. RESULTS A total of 168 volunteers completed the pre-education assessment test and were randomized into four groups. Pre-education assessment test scores were similar among the groups (p > 0.05). Of 168 volunteers, 130 (77.3%) completed the posteducation assessment test. Posteducation assessment test scores were significantly higher in the three-dimensional (3D) animation + cadaveric video group (p < 0.01), the 3D animation group (p < 0.01) and the cadaveric group (p < 0.01) compared with the textbook group. Moreover, posteducation assessment test scores were significantly higher in the 3D animation + cadaveric video group than the 3D animation group (p < 0.01). Each group's posteducation assessment test scores were significantly higher than the pre-education assessment test scores, with the exception of the textbook group. CONCLUSION Our study demonstrates that 3D animation + cadaveric videos, 3D animation alone and cadaveric videos are all superior to a surgical textbook when teaching laparoscopic rectal cancer surgery. Finally, our results show that 3D animation and cadaveric videos are also superior to textbooks in enabling an understanding of rectal surgery.

Abstract
Background: The role of minimally invasive surgery (MIS) in locally advanced colorectal cancers (CRCs) suspected of direct invasion to adjacent organs or structures remains controversial. The aim of this study is to verify the safety and feasibility of minimally invasive multivisceral resection (MVR) surgery for locally advanced CRCs compared with conventional open surgery. Materials and Methods: Prospectively collected data from patients who underwent MVR for locally advanced CRCs from 2007 to 2017 were retrospectively reviewed. Patients with preoperative clinically suspected T4b stage cancers were enrolled in the study. Results: There were 30 and 19 patients in the MIS and open surgery groups, respectively. Seven patients in the MIS group required conversion, and the most common reason for conversion was ureter and bladder invasion. Tumor sizes were significantly larger in the open group (5.46 cm versus 7.48 cm, P = .010), whereas the MIS group included more patients with rectal cancers (56.7% versus 21%, P = .021). No differences were observed between the two groups in terms of operation time, estimated blood loss, and postoperative hospital stay. Curative (R0) resection was achieved in all patients, and the median follow-up period was 23 months. The 3-year overall survival in the MIS group was 73.6% and 77.9% in the open group (P = .445), and the 3-year total disease-free survival (DFS) was 59.2% and 51.4%, respectively (P = .695). Three-year local DFS was 83.3% for the MIS group, and 51.4% for the open group (P = .120). Conclusion: MIS for primary T4b CRCs without urinary tract invasion is safe and feasible.

Analysis of the Positional Relationship Among the Operator, Camera, and Monitor: Overcoming the Difficulties of Mirror-image Conditions During Laparoscopic Surgery. Surg Laparosc Endosc Percutan Tech 2021; 31:513-518.

Abstract
BACKGROUND Although methods to overcome difficulties associated with mirror-image conditions have been investigated, the ideal spatial relationship among the operator line of sight, monitor location, and camera location remains unclear. Moreover, the best training method for improving laparoscopic surgical skills under varying operator line of sight, camera, and monitor positions is unknown. We aimed to investigate the role of laparoscopic training under mirror-image conditions in improving surgical efficiency and whether prior surgical experience affects such training. METHODS This prospective study was conducted at the Department of Surgical Oncology, Tokyo University, Japan. Twenty-five surgeons participated. Novice (n=14), trained (n=7), and expert (n=4) participants performed the simulated task in a box trainer while varying the positional relationships among the surgeons, camera, and monitor. Five patterns were repeatedly performed 5 times per day for 4 days over 2 weeks. RESULTS The most significant differences in terms of the time required to complete the task under mirror-image conditions among the 3 groups were on day 1 (novices: 185.8 s, trained: 79.7 s, and experts: 46.5 s, P=0.009). However, after 4 days of training, the corresponding times did not differ among the 3 groups (26.0, 30.7, and 23.1 s, respectively; P=0.415). Laparoscopic training was sufficiently effective under mirror-image conditions. CONCLUSIONS Mirror-image surgical conditions provided the most difficult setting, because surgeons and assistants often became disoriented, and task performance was most degraded. However, just 4 days of training was found to be sufficient to overcome the difficulties encountered while performing laparoscopic procedures under mirror-image conditions.

Abstract
Modern perioperative medicine has dramatically altered the care for patients undergoing major surgery. Anaesthetic and surgical practice has been directed at mitigating the surgical stress response and reducing physiological insult. The development of standardised enhanced recovery programmes combined with minimally invasive surgical techniques has lead to reduction in length of stay, morbidity, costs, and improved outcomes. The enhanced recovery after surgery (ERAS) society and its national chapters provide a means for sharing best practice in this field and developing evidence based guidelines. Research has highlighted persisting challenges with compliance as well as ensuring the effectiveness and sustainability of ERAS. There is also a growing need for increasingly personalised care programmes as well as complex geriatric assessment of frailer patients. Continuous collection of outcome and process data combined with machine learning, offers a potentially powerful solution to delivering bespoke care pathways and optimising individual management. Long-term data from ERAS programmes remain scarce and further evaluation of functional recovery and quality of life is required.

Evaluation of an early-stage innovation for full-thickness excision of benign colonic polyps using the IDEAL framework. Colorectal Dis 2019; 21:1004-1016.

Abstract
AIMS Colectomy is the current approach for patients with endoscopically unresectable benign polyps but risks considerable morbidity. Full-thickness laparoendoscopic excision (FLEX) is a novel procedure, specifically developed to treat endoscopically unresectable benign colonic polyps, which could reduce the treatment burden of the current approach and improve outcomes. However, traditional evaluations of surgical innovations lack methodological rigour. This study reports the development and feasibility of the FLEX procedure in selected patients. METHOD A prospective development study using the Idea, Development, Evaluation, Assessment, Long-term study (IDEAL) framework was undertaken, by one surgeon, of the FLEX procedure in selected patients with endoscopically unresectable benign colonic polyps. Three-dimensional (3D)-CT colonography reconstructions were used preoperatively to rehearse patient-specific, critical manoeuvres. Targetted, full-thickness excision was performed: after marking the margin of the caecal polyp using circumferential endoscopic argon plasma coagulation, transmural endoscopic sutures were used to evert the bowel and resection was undertaken by laparoscopic linear stapling. Feasibility outcomes (establishing 'local success') included evidence of complete polyp resection without adverse events (especially safe closure of the excision site). RESULTS Ten patients [median (interquartile range) age: 74 (59-78) years] with polyp median diameters of 35 (30-41) mm, were referred for and consented to receive the FLEX procedure. During the same time frame, no patient underwent colectomy for benign polyps. One further patient received FLEX for local excision of a presumed malignant polyp because severe comorbidity prohibited standard procedures. The FLEX procedure was successfully performed locally, with complete resection of the polyp and safe closure of the excision site, in eight patients. Three noncompleted procedures were converted to laparoscopic segmental colectomy under the same anaesthetic because of endoscopic inaccessibility (two patients) and transcolonic suture failure (one patient). CONCLUSIONS The FLEX procedure is still under development. Early data demonstrate that it is safe for excision of selected benign polyps. Modifications to transcolonic suture delivery are now required and there is a need for wider adoption before more definitive evaluation can be performed.

Abstract
BACKGROUND/AIM Extended total mesorectal excision (ETME) is defined as en bloc resection of the adjacent organs outside the mesorectal fascia, that is indicated in cases with locally advanced lower rectal cancer (T4 tumor). The aim of this study was to evaluate the clinical and oncological outcomes of laparoscopic ETME (L-ETME) for locally advanced lower rectal cancer. PATIENTS AND METHODS The present study analyzed clinical outcomes and oncological outcomes of 11 consecutive patients who underwent L-ETME for cT4 lower rectal cancer in Nagasaki Medical Center between 2012 and 2015. RESULTS Of the 11 patients, 7 underwent neoadjuvant therapy, and 7 underwent pelvic node dissection. One case (7.1%) underwent resection of anterior organs (prostate), 6 cases (54.5%) had resection of the lateral organs (neurovascular bundle, hypogastric nerve, pelvic plexus, ovary, and internal iliac blood vessels) and 4 cases (36.4%) had resection of both anterior and lateral organs. In all cases enrolled in this study, R0 resection was achieved. The median operation time and intraoperative blood loss were 416 min and 350 ml, respectively. The postoperative complication rate was 18.2% (2/11). The 3-year overall survival rate was 79.5%, and the 3-year local recurrence-free survival rate was 87.5%. There was no mortality and no re-operation in this series. CONCLUSION The results of the present study suggest that L-ETME is feasible and has efficacy for locally advanced lower rectal cancer.

Induced Bias Due to Crossover Within Randomized Controlled Trials in Surgical Oncology: A Meta-regression Analysis of Minimally Invasive versus Open Surgery for the Treatment of Gastrointestinal Cancer. Ann Surg Oncol 2017; 25:221-230. [PMID: 29110271 PMCID: PMC5740197 DOI: 10.1245/s10434-017-6210-y] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2017] [Indexed: 12/14/2022]
Abstract
BACKGROUND Randomized controlled trials (RCTs) inform clinical practice and have provided the evidence base for introducing minimally invasive surgery (MIS) in surgical oncology. Crossover (unplanned intraoperative conversion of MIS to open surgery) may affect clinical outcomes and the effect size generated from RCTs with homogenization of randomized groups. OBJECTIVES Our aims were to identify modifiable factors associated with crossover and assess the impact of crossover on clinical endpoints. METHODS A systematic review was performed to identify all RCTs comparing MIS with open surgery for gastrointestinal cancer (1990-2017). Meta-regression analysis was performed to analyze factors associated with crossover and the influence of crossover on endpoints, including 30-day mortality, anastomotic leak rate, and early complications. RESULTS Forty RCTs were included, reporting on 11,625 patients from 320 centers. Crossover was shown to affect one in eight patients (mean 12.6%, range 0-45%) and increased with American Society of Anesthesiologists score (β = + 0.895; p = 0.050). Pretrial surgeon volume (β = - 2.344; p = 0.037), composite RCT quality score (β = - 7.594; p = 0.014), and site of tumor (β = - 12.031; p = 0.021, favoring lower over upper gastrointestinal tumors) showed an inverse relationship with crossover. Importantly, multivariate weighted linear regression revealed a statistically significant positive correlation between crossover and 30-day mortality (β = + 0.125; p = 0.033), anastomotic leak rate (β = + 0.550; p = 0.004), and early complications (β = + 1.255; p = 0.001), based on intention-to-treat analysis. CONCLUSIONS Crossover in trials was associated with an increase in 30-day mortality, anastomotic leak rate, and early complications within the MIS group based on intention-to-treat analysis, although our analysis did not assess causation. Credentialing surgeons by procedural volume and excluding high comorbidity patients from initial trials are important in minimizing crossover and optimizing RCT validity.

Abstract
Perioperative multimodal analgesia uses combinations of analgesic medications that act on different sites and pathways in an additive or synergistic manner to achieve pain relief with minimal or no opiate consumption. Although all medications have side effects, opiates have particularly concerning, multisystemic, long-term, and short-term side effects, which increase morbidity and prolong admissions. Enhanced recovery is a systematic process addressing each aspect affecting recovery. This article outlines the evidence base forming the current multimodal analgesia recommendations made by the Enhanced Recovery After Surgery Society (ERAS). We describe current evidence and important future directions for effective perioperative multimodal analgesia in enhanced recovery pathways.

Abstract
INTRODUCTION Laparoscopic surgery has become the standard for colorectal cancer resection in the UK but it can be technically challenging in patients who are obese. Patients whose body fat is mainly inside the abdominal cavity are more challenging than those whose fat is mainly outside the abdominal cavity. Abdominal fat ratio (AFR) is a simple parameter proposed by the authors to aid identification of this subgroup. MATERIALS AND METHODS All 195 patients who underwent elective, laparoscopic colorectal cancer resections from March 2010 to November 2013 were included in the study. For patients who were obese (body mass index greater than 30), preoperative staging computed tomography was used to determine AFR. This was assessed by two different, blinded observers and compared with conversion rate. RESULTS Of the 195 patients, 58 (29.7%) fell into the obese group and 137 (70.3%) into the non-obese group. The median AFR of the obese group that were converted to open surgery was significantly higher at 5.9 compared with those completed laparoscopically (3.3, P = 0.0001, Mann-Whitney). There was no significant difference in conversion rate when looking at body mass index, tumour site or size. DISCUSSION Previous studies have found body mass index, age, gender, previous abdominal surgery, site and locally advanced tumours to be associated with an increased risk of conversion. This study adds AFR to the list of risk factors. CONCLUSION AFR is a simple, reproducible parameter which can help to predict conversion risk in obese patients undergoing colorectal cancer resection.

Abstract
Abstract
Background
The aim was to evaluate the applicability of laparoscopic surgery in the treatment of primary rectal cancer in a training unit.
Methods
A cohort analysis was undertaken of consecutive patients undergoing elective surgery for primary rectal cancer over a 7-year interval. Data on patient and operative details, and short-term clinicopathological outcomes were collected prospectively and analysed on an intention-to-treat basis.
Results
A total of 306 patients (213 men, 69·6 per cent) of median (i.q.r.) age 67 (58–73) years with a median body mass index of 26·6 (23·9–29·9) kg/m2 underwent surgery. Median tumour height was 8 (6–11) cm from the anal verge, and 46 patients (15·0 per cent) received neoadjuvant radiotherapy. Seven patients (2·3 per cent) were considered unsuitable for laparoscopic surgery and underwent open resection; 299 patients (97·7 per cent) were suitable for laparoscopic surgery, but eight were randomized to open surgery as part of an ongoing trial. Some 291 patients (95·1 per cent) underwent a laparoscopic procedure, with conversion required in 29 (10·0 per cent). Surgery was partially or completely performed by trainees in 72·4 per cent of National Health Service patients (184 of 254), whereas private patients underwent surgery primarily by consultants. Median postoperative length of stay for all patients was 6 days and the positive circumferential resection margin rate was 4·9 per cent (15 of 306).
Conclusion
Supervised trainees can perform routine laparoscopic rectal cancer resection.

Abstract
AIM The study compared the outcome of laparoscopic and open surgery in daily practice when performed in a strict Enhanced Recovery After Surgery (ERAS) environment. METHOD Two-hundred and ninety-two consecutive patients who received elective surgery, in three Swedish ERAS centres, for cancer or adenoma in the right colon in the period 1 January 2011 to 31 December 2012, were prospectively registered in a Web-based ERAS database. Peri-operative data were collected from the database and patient charts. The primary end-points included postoperative recovery and morbidity. The secondary objective was to identify preoperative variables that influenced the selection of patients for laparoscopic or open surgery. RESULTS One-hundred and twenty-three (42%) patients were selected for laparoscopic surgery. The overall preoperative ERAS-compliance rate was 87% and no significant difference was seen between the surgical techniques. In multivariate analysis, patients treated with laparoscopy had significantly earlier pain control (2.4 ± 3.2 days vs 4.2 ± 5.9 days; P = 0.016) and a shorter length of hospital stay (LOS) (4 days vs 6 days; P = 0.002) compared with open surgery. There was no significant difference in the complication rate [18.7% vs 21.3%; OR = 1.0 (95% CI: 0.5-2.0)], the number of lymph nodes removed or the rate of R0 resection between laparoscopic and open surgery. Tumours selected for laparoscopy were generally smaller, had a lower T-stage and were predominantly situated in the caecum and the ascending colon compared with those of patients selected for open surgery. CONCLUSION The use of laparoscopy in routine right-sided colectomy in an ERAS environment, with data on outcome corrected for selection bias, may result in faster recovery compared with open surgery.

Abstract
BACKGROUND Laparoscopic liver surgery is expanding. Most laparoscopic liver resections for colorectal carcinoma metastases are performed subsequent to the resection of the colorectal primary, raising concerns about the feasibility and safety of advanced laparoscopic liver surgery in the context of an abdomen with possible postoperative adhesions. The aim was to compare the outcome of laparoscopic hepatectomy for colorectal metastases after open versus laparoscopic colorectal surgery. METHODS This observational, multicenter study reviewed 394 patients undergoing laparoscopic minor and major liver resection for colorectal carcinoma metastases. Main outcome measures were intraoperative unfavorable incidents and short-term results in patients who had previous open versus laparoscopic colorectal cancer surgery. RESULTS Three hundred six patients (78%) had prior open and 88 (22%) had prior laparoscopic colorectal resection. Laparoscopic major hepatectomies were undertaken in 63 (16%). Intraoperative unfavorable incidents during laparoscopic liver surgery were significantly higher among patients who had prior open colorectal surgery (26%) compared with the laparoscopic group (14%; P = .017). Positive resection margins and postoperative complications were not associated with the approach adopted for the resection of the primary cancer. On multivariate logistic regression analysis, intraoperative unfavorable incidents were associated significantly only with prior open colorectal surgery (odds ratio, 2.8; P = .006) and laparoscopic major hepatectomy (odds ratio, 2.4; P = .009). CONCLUSION Laparoscopic minor hepatectomy can be performed safely in patients who have undergone previous open colorectal surgery. Laparoscopic major hepatectomy after open colorectal surgery may be challenging. Careful risk assessment in the decision-making process is required not to compromise patient safety and to guarantee the expected benefits from the minimally invasive approach.

Abstract
INTRODUCTION A single experienced laparoscopic colorectal surgeon introduced an outreach preceptorship programme (OPP) for laparoscopic colorectal surgery (LCS) in Wales with the aim of supporting consultants in the early stages of their learning curve, as well as to help avoid some of the problems faced by self-taught laparoscopic surgeons. The structured programme consisted of a minimum 1 day master class at the preceptor's operating theatre, followed by multiple outreach visits by the preceptor. The aim of this study was to evaluate the effectiveness and early experience of this programme. MATERIALS AND METHODS Clinical end-points (conversions, morbidity/mortality and length of hospital stay) were analysed from a prospectively maintained database. Evaluation of the programme was based on interviews with the preceptee surgeons performed by a neutral observer. RESULTS Between May 2008 and July 2010, 11 Consultants (six hospitals) were preceptored (two still in programme). 66 cases (20 in the master class, 46 as an outreach service) were performed as a part of this programme. CLINICAL OUTCOME Conversion rate and 30-day mortality was 1.5%. Morbidity was reported at 12% (8/66) and median length of stay was 6 days. Programme evaluation: All interviewed respondents found the master class and outreach service to be well-organised and would recommend it to their colleagues. The median number of outreach visits per hospital was 5. All the preceptees have performed independent cases since the programme. CONCLUSION This OPP delivers one-to-one coaching at the point of service delivery and has been shown to be effective in achieving safe transference of skills to those wishing to develop a service for LCS.

Abstract
PURPOSE Laparoscopic resection and a multimodal approach known as an enhanced recovery program (ERP) have been major changes in colorectal perioperative care that have improved clinical outcomes for colorectal cancer resection. EnROL (Enhanced Recovery Open Versus Laparoscopic) is a multicenter randomized controlled trial examining whether the benefits of laparoscopy still exist when open surgery is optimized within an ERP. PATIENTS AND METHODS Adults with colorectal cancer suitable for elective resection were randomly assigned at a ratio of 1:1 to laparoscopic or open surgery within an ERP, stratified by center, cancer site (colon v rectum), and age group (<66 v 66-75 v >75 years) using minimization. The primary outcome was physical fatigue at 1 month postsurgery. Secondary outcomes included hospital stay, complications, other patient-reported outcomes (PROs), and physical function. Patients and outcome assessors were blinded until 7 days postsurgery or discharge if earlier. Central independent and blinded pathologic assessment of surgical quality was undertaken. RESULTS A total of 204 patients (laparoscopy, n=103; open surgery, n=101) were recruited from 12 UK centers from July 2008 to April 2012. One-month physical fatigue scores were similar in both groups (mean: laparoscopy, 12.28; 95% CI, 11.37 to 13.19 v open surgery, 12.05; 95% CI, 11.14 to 12.96; adjusted mean difference, -0.23; 95% CI, -1.52 to 1.07). Median total hospital stay was significantly shorter after laparoscopic surgery (median: laparoscopy, 5; interquartile range [IQR], 4 to 9 v open surgery, 7; IQR, 5 to 11 days; P=.033). There were no differences in other secondary outcomes or in specimen quality after central pathologic review. CONCLUSION In patients treated by experienced surgeons within an ERP, physical fatigue and other PROs were similar in both groups, but laparoscopic surgery significantly reduced length of hospital stay.

Abstract
PURPOSE To evaluate the technical feasibility, safety and oncological outcomes of laparoscopic lateral pelvic lymph node dissection in patients with advanced low rectal cancer. METHODS Laparoscopic lateral pelvic lymph node dissection was performed in 18 patients from November 2009 to September 2012. The data regarding the patient demographics, surgical outcomes and short-term oncological outcomes were analyzed. RESULTS In all 18 patients, the procedures were completed without conversion to open surgery. The mean length of the operation was 603.7 min (473-746 min). The mean number of harvested lateral pelvic lymph nodes was 16.9 (7-27), and five patients (27.8 %) had lymph node metastases. The postoperative mortality and morbidity rates were 0 and 16.7 %, respectively. Three patients developed Grade 2 urinary retention. No local recurrence had developed after a mean follow-up period of 23.6 months. CONCLUSION Laparoscopic lateral pelvic lymph node dissection is technically feasible, safe and oncologically acceptable within the limitations of the short-term follow-up period.

Abstract
AIMS The purpose of this study was to evaluate the technical feasibility, safety and oncological outcomes of laparoscopic resection for middle and low rectal cancers. MATERIALS AND METHODS From January 2004 to December 2011, review of prospectively collected database revealed a series of 97 laparoscopic resections for middle and low rectal cancer within 10 cm from the anal verge. Five patients with multiple primary cancers were excluded. Operation time, intra-operative blood loss, surgical complications, duration of hospital stay, retrieved lymph nodes, tumour, node, metastasis (TNM) stage and recurrence were retrospectively analysed. RESULTS Tumours were located within 5 cm of the anal verge in 28 patients (30.4%) and from 5 cm to 10 cm in 64 patients (69.6%). Abdominoperineal resection was performed in 12 patients (13%), and conversion to open surgery was necessary in four patients (4.3%). The mean operation time was 199.7 min (range 105-450 min) and the mean intra-operative blood loss was 169.9 mL (range 20-800 mL). The mean hospital stay was 11.8 days (range 5-45 days) and a mean of 12.2 lymph nodes were retrieved. The incidence of surgical complications was 11.9%, including anastomosis site leakage in five patients (5.4%). There were no mortalities resulting from laparoscopic surgery. The median follow-up period was 28.4 months (range 7-85 months). Recurrence occurred in eight patients (8.7%). CONCLUSIONS Laparoscopic resection can be applied for middle and low rectal cancers with acceptable surgical and oncological outcomes.

Abstract
BACKGROUND It has been evident for a while that the result after resection for colon cancer may not have been optimal. Several years ago, this was showed by some leading surgeons in the USA but a concept of improving results was not consistently pursued. Later, surgeons in Europe and Japan have increasingly adopted the more radical principle of complete mesocolic excision (CME) as the optimal approach for colon cancer. The concept of CME is a similar philosophy to that of total mesorectal excision for rectal cancer and precise terminology and optimal surgery are key factors. METHOD There are three essential components to CME. The main component involves a dissection between the mesenteric plane and the parietal fascia and removal of the mesentery within a complete envelope of mesenteric fascia and visceral peritoneum that contains all lymph nodes draining the tumour area (Hohenberger et al., Colorectal Disease 11:354-365, 2009; West et al., J Clin Oncol 28:272-278, 2009). The second component is a central vascular tie to completely remove all lymph nodes in the central (vertical) direction. The third component is resection of an adequate length of bowel to remove involved pericolic lymph nodes in the longitudinal direction. RESULT The oncological rationale for CME and various technical aspects of the surgical management will be explored. CONCLUSION The consensus conference agreed that there are sound oncological hypotheses for a more radical approach than has been common up to now. However, this may not necessarily apply in early stages of the tumour stage. Laparoscopic resection appears to be equally well suited for resection as open surgery.

Abstract
After the rapid acceptance of laparoscopy to manage multiple benign diseases arising from gastrointestinal districts, some surgeons started to treat malignancies by the same way. However, if the limits of laparoscopy for benign diseases are mainly represented by technical issues, oncologic outcomes remain the foundation of any procedures to cure malignancies. Cancerous patients represent an important group with peculiar aspects including reduced survival expectancy, worsened quality of life due to surgery itself and adjuvant therapies, and challenging psychological impact. All these issues could, potentially, receive a better management with a laparoscopic surgical approach. In order to confirm such aspects, similarly to testing the newest weapons (surgical or pharmacologic) against cancer, long-term follow-up is always recommendable to assess the real benefits in terms of overall survival, cancer-free survival and quality of life. Furthermore, it seems of crucial importance that surgeons will be correctly trained in specific oncologic principles of surgical oncology as well as in modern miniinvasive technologies. Therefore, laparoscopic treatment of gastrointestinal malignancies requires more caution and deep analysis of published evidences, as compared to those achieved for inflammatory bowel diseases, gastroesophageal reflux disease or diverticular disease. This review tries to examine the evidence available to date for the use of laparoscopy and robotics in malignancies arising from the gastrointestinal district.

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.

Learning curve and case selection in laparoscopic colorectal surgery: systematic review and international multicenter analysis of 4852 cases. Dis Colon Rectum 2012; 55:1300-10.

Abstract
BACKGROUND The learning curve for laparoscopic colorectal surgery has not been conclusively analyzed. No reliable framework for case selection during training is available. OBJECTIVE The aim of this study was to analyze the length of the learning curve of laparoscopic colorectal surgeons and to recommend a case selection framework at the early stage of independent practice. DATA SOURCES Medline (1988-2010, October week 4) and Embase (1988-2010) were used for the literature review, databases were retrieved from the authors, and expert opinion was surveyed. STUDY SELECTION Studies describing the learning curve of laparoscopic or laparoscopically assisted colorectal surgery were selected. INTERVENTION No interventions were performed. MAIN OUTCOME MEASURES Learning curves were analyzed by using risk-adjusted, bootstrapped cumulative sum curves. Conversions and complications were independent variables in a multilevel random-effects regression model. Recommendations are based on analysis of ORs and a structured expert opinion gauging process. RESULTS Twenty-three studies were identified, showing great disparity on the length of the learning curve. Seven studies, representing 4852 cases (19 surgeons), were analyzed. Risk-adjusted cumulative sum charts demonstrated the length of the learning curves to be 152 cases for conversions, 143 for complications, 96 for operating time, 87 for blood loss, and 103 for length of stay. Body mass index and pelvic dissection (rectum), especially in male patients, independently increased the risk of complication and conversion. The expert survey revealed that increasing T stage and complicated inflammatory disease are likely to increase the complexity of the case. Based on this evidence, a framework for case selection in training was proposed. LIMITATIONS The generalizability of the study results maybe reduced because of inconsistent data quality and individual variations in the length of the learning curve CONCLUSIONS This multicenter database suggests a length of the learning curve of 88 to 152 cases. The use of the suggested framework may prevent high conversion and complication rates during the learning curve.

Abstract
Background With an increasing percentage of colorectal resections performed laparoscopically nowadays, there is more emphasis on training “before the job” on operative skills, including the comprehension of specific laparoscopic surgical anatomy. As integration of technical skills with correct interpretation of the anatomical image must be incorporated in laparoscopic training, a human specimen training model with special emphasis on surgical anatomy was developed. Methods The new embalming method Anubifix™ combines long-term high-quality embalming of human bodies with almost normal flexibility and plasticity, and the body can be kept operational as long as conventionally embalmed human specimens. A colorectal training model was created in a specimen in which anatomical landmarks of colorectal anatomy were permanently colored to explore laparoscopic colorectal anatomy in a skills training setting. Airtight closure of the abdominal wall permits the creation of pneumoperitoneum. Residents were asked to test the model by mobilizing the small and large bowels and expose the central vessels and ureters. Afterward they were asked to fill out an eight-item questionnaire about the model. Results Eleven surgical residents in their first and second year of training participated. Responses to the questionnaire showed that a majority of residents considered the model to be representative of the real situation and superior to animal models or virtual reality simulators, and helped to improve the knowledge of three-dimensional anatomy and laparoscopic skills. Conclusion The new training model for laparoscopic colorectal surgery proved to be a high-quality tool, concentrating on laparoscopic colorectal anatomy in a skills training setting. We believe it may be a valuable adjunct to residency training programs based on the principle of “training before the job.”

Abstract
BACKGROUND This review aims to present a consensus for optimal perioperative care in colonic surgery and to provide graded recommendations for items for an evidenced-based enhanced perioperative protocol. METHODS Studies were selected with particular attention paid to meta-analyses, randomised controlled trials and large prospective cohorts. For each item of the perioperative treatment pathway, available English-language literature was examined, reviewed and graded. A consensus recommendation was reached after critical appraisal of the literature by the group. RESULTS For most of the protocol items, recommendations are based on good-quality trials or meta-analyses of good-quality trials (quality of evidence and recommendations according to the GRADE system). CONCLUSIONS Based on the evidence available for each item of the multimodal perioperative-care pathway, the Enhanced Recovery After Surgery (ERAS) Society, International Association for Surgical Metabolism and Nutrition (IASMEN) and European Society for Clinical Nutrition and Metabolism (ESPEN) present a comprehensive evidence-based consensus review of perioperative care for colonic surgery.

Abstract
AIM Proponents suggest that laparoscopic colorectal resection might be achievable in up to 90% of cases, while keeping conversion rates below 10%. This unselected prospective case series reports on the proportion of patients having a completed laparoscopic colorectal resection in two units where laparoscopic colorectal practice is well established and readily available. METHOD All patients undergoing elective and emergency colorectal resection during a 6-month period were identified. The underlying pathology and the surgical approach (laparoscopic or open) were recorded. The contraindications to laparoscopic resection were also documented. The need and rationale for conversion to an open approach were recorded. RESULTS In total, 205 consecutive patients (160 elective and 45 emergency procedures) underwent colorectal resection for malignancy [117 (57%) patients] and benign pathology [88 (43%) patients]. Laparoscopic resection was attempted in 127/205 (62%) patients and 31/127 (24%) of these were converted to open surgery. The main reasons for not attempting laparoscopic resection were locally advanced disease and emergency surgery. The commonest reasons for conversion were advanced disease and to allow completion of rectal dissection and/or cross-stapling of the rectum. CONCLUSION Despite a special interest in laparoscopic colorectal surgery of the two colorectal units who provided the data for this study, fewer than half (96/205; 47%) of the patients in this consecutive unselected series who were undergoing major colorectal resection had the procedure completed laparoscopically.

Abstract
BACKGROUND Laparoscopic resection for colorectal cancer has become popular. However, no previous studies have compared the laparoscopic and open approaches for colorectal cancer adherent to adjacent organs. This study analyzed the short- and long-term survival outcomes after laparoscopic multivisceral resection of the locally advanced primary colorectal cancer compared with open procedure in an effort to address appropriate patient selection. METHODS From a prospectively collected database, 54 patients with locally advanced primary colorectal cancer who had undergone multivisceral resection from March 2001 to September 2009 were identified. Laparoscopic and open surgeries were selectively performed for 38 and 16 patients, respectively. RESULTS The two groups had similar demographics, with no differences in age, sex, and comorbidity. However, five emergency or urgency operations were included in the open group. No differences existed between the two groups in terms of tumor node metastasis (TNM) staging, histologic tumor infiltration rates, or curative resection rates. Three patients (7.9%) in the laparoscopic group required conversion to open procedure. In the laparoscopic group, the operation time was longer (330 vs. 257 min; p = 0.018), the volume of blood loss was less (269 vs. 638 ml; p = 0.000), and the time until return of bowel movement was shorter (3.7 vs. 4.7 days; p = 0.029) than in the open group. The perioperative morbidity rates were similar in the two groups (21.1% vs. 43.7%; p = 0.107), and no perioperative mortality occurred in either group. The mean follow-up period after curative resection was 40 months in the laparoscopic group and 35 months in the open group. The two groups showed similar rates for local recurrence (7.7% vs. 27.3%; p = 0.144) and distant metastasis (15.4% vs. 45.5%; p = 0.091). The overall 5-year survival rate was 60.5% for the laparoscopic group and 47.7% for the open group (p = 0.044, log-rank test). In terms of TNM stages, the overall 5-year survival rate for pathologic stage 3 disease was 58.3% for the laparoscopic group and 25% for the open group (p = 0.022, log rank test), but no difference was noted for the stage 2 patients (p = 0.384). CONCLUSIONS No adverse long-term oncologic outcomes of laparoscopic resection were observed in this study. Although inherent limitations exist in this nonrandomized study, laparoscopic multivisceral resection seems to be a feasible and effective treatment option for colorectal cancer for carefully selected patients. Patients with colon cancer should be much more carefully selected for laparoscopic multivisceral resection than patients with rectal cancer because anatomic uncertainty can make oncologic en bloc resection incomplete.

Abstract
OBJECTIVE To examine the trends in the uptake of laparoscopic resection for colorectal cancer. DESIGN AND SETTING Retrospective analysis of Australia-wide data on elective resections for colorectal cancer over the 8 financial years 2000-01 to 2007-08, obtained from the National Hospital Morbidity Database. MAIN OUTCOME MEASURES National trends in annual percentage of colorectal resections for cancer that were conducted laparoscopically for each year, stratified by hospitals conducting a high volume of elective resections (40 or more/year) versus a low volume, and by public versus private hospitals. RESULTS For all Australian hospitals combined, the percentage of resections for colon cancer conducted laparoscopically increased from 2.4% in 2000-01 to 27.5% in 2007-08. For rectal cancer, this increase was from 1.1% to 21.5%. The largest increases were seen in high-volume private hospitals (colon cancer, 2.7% to 34.1%; rectal cancer, 1.5% to 26.2%), but increases also occurred in high-volume public hospitals (colon cancer, 2.7% to 32.2%; rectal cancer, 0.5% to 20.3%), low-volume private (colon cancer, 3.8% to 27.1%; rectal cancer, 2.4% to 25.5%) and low-volume public (colon cancer, 1.1% to 17.0%; rectal cancer, 0.5% to 13.8%) hospitals. CONCLUSIONS The use of laparoscopic resection for colorectal cancer has increased throughout Australian hospitals. Our findings provide the data necessary to ensure adequate resource allocation by the appropriate medical bodies to achieve optimal success in the uptake of laparoscopic resection for colorectal cancer in Australia.

Abstract
Current literature suggests that minimally invasive distal gastrectomy (MIDG) may enhance post-operative recovery and decrease morbidity compared to open surgery (ODG) in patients with gastric cancer. A meta-analysis of six Prospective Randomized Trials comparing MIDG (343 patients) and ODG (323 patients) for gastric cancer was conducted. MIDG was associated with increased operative time, reduced blood loss and overall morbidity. There was not sufficient data to draw solid conclusions about the oncologic quality of MIDG.

Abstract
AIM To evaluate the technical feasibility, safety, and oncological outcomes of laparoscopic extended lateral pelvic lymph node dissection (LPLD) following total mesorectal excision (TME) in patients with advanced low rectal cancer. STUDY DESIGN A review of a prospectively collected database at Kyungpook National University Hospital from May 2003 to September 2009 revealed a series of 16 consecutive laparoscopic TME with LPLD patients with preoperative diagnosis of lateral node metastasis. Data regarding patient demographics, operating time, perioperative blood loss, surgical morbidity, lateral lymph node status, functional outcome, and mid-term oncologic result were analyzed. RESULTS In all 16 patients, the procedures were completed without conversion to open surgery. During the study period, robot-assisted laparoscopic LPLD was performed in two patients. Mean operative time was 321.9 min (range 220-510 min). The mean number of lateral lymph nodes harvested was 9.1 (range 3-19), and a total of nine patients (56.2%) had lymph node metastases. Postoperative mortality and morbidity were 0 and 31.2%, respectively. Recovery after the procedure was rapid, and mean hospital stay was 9.9 days (range 7-14 days). With median follow-up of 38 months, among nine patients who were lateral pelvic node positive, one patient experienced pelvic side-wall local recurrence (11.2%). CONCLUSIONS Laparoscopic TME with LPLD is safe and feasible, with the advantage of a minimally invasive approach. Prospective controlled study comparing laparoscopy and conventional open surgery with long-term follow-up evaluation is needed to confirm the authors' initial experience.

Abstract
BACKGROUND Laparoscopic surgery is increasingly proposed as the gold standard technique for colorectal resections and is offered to greater numbers of patients. To meet the rising service demands, more trainees and established consultants need to learn the technique. We sought to establish whether it is feasible and safe to train on a large proportion of patients without adversely affecting clinical outcome or smooth running of clinical service. METHODS Between September 2006 and July 2008, four senior trainees of the Wessex Specialist Registrar training rotation were involved in training in laparoscopic colorectal surgery. Major colorectal resections were separated into clearly defined modules for training purposes. Right and left hemicolectomies each comprised two modules, and low anterior resection comprised three modules. Prospective data on consecutive patients undergoing laparoscopic colorectal surgery were collected. Data included type of surgery, module of procedure performed by trainee or trainer, body mass index (BMI), conversion rates, median operative time, complications, length of hospital stay, and mortality. RESULTS During the study period 227 colorectal resections were attempted laparoscopically. Of these, 216 (96%) proved suitable for training and 97% were completed laparoscopically. Some 23% of patients were American Society of Anesthesiologists score (ASA)≥3; 35% had a BMI≥28; 38% had a history of previous laparotomy. Trainees performed 96% (142/148) of right hemicolectomy modules, 99% (154/156) of left hemicolectomy modules, and 67% (128/192) of rectal resection modules. Each trainee was competent to do right and left hemicolectomy at the end of the training period. Four patients (2%) required further surgery for postoperative complications. Of the procedures completed by the trainees, 155/171 (91%) cancer resections were potentially surgically curative, and R0 resections were achieved in 99%. The readmission rate was 10% (22/216) and median length of hospital stay was 4 days. Postoperative mortality was zero. CONCLUSIONS Using a modular approach it is possible to provide effective training during almost all laparoscopic colorectal resections while achieving good clinical outcomes for the patients.

Abstract
AIM Laparoscopic colorectal surgery includes operative procedures of varying complexity, and traditional assessment tools may not be enough to assess competence. This study defines quantitative tools for assessing proficiency in laparoscopic colorectal surgery. METHOD A single surgeon's 11-year experience was subdivided into five phases with equal numbers of patients. A tool-kit, with specific tools defined as the complexity score, the conversion score, the technical score, the training score and the proficiency score, has been developed and used to evaluate each phase of the experience. RESULTS There were 400 patients, with 80 in each of the five phases. The complexity score increased from 23.75 to 63.75 over the five phases. Similar increases were also demonstrable in the conversion score (from 0.45 to 15.45), the technical score (from 30 to 96.5), the training score (from 5.8 to 34.8) and the overall proficiency score (from 15 to 52.63). CONCLUSION The results show that it is possible to quantify the workload in laparoscopic colorectal surgery and to assess increasing proficiency using a simple, reproducible and reliable tool-kit.

Abstract
BACKGROUND Laparoscopic resection for colon cancer has been proven to have a similar oncological efficacy compared to open resection. Despite this, it is performed by a minority of colorectal surgeons. The aim of our study was to evaluate the short-term clinical, oncological and survival outcomes in all patients undergoing laparoscopic resection for colon cancer. METHODS From July 2005 to December 2008, 202 consecutive patients underwent laparoscopic resection for colon cancer. Surgery was analysed on an intention to treat basis. The mean follow-up was 24.3 months. RESULTS Two hundred twenty-two patients underwent resection for colon cancer. Two hundred two underwent laparoscopic resection (91%). One hundred sixteen were male patients. Mean age was 65.9 years (range = 24-91). The median length of stay was 6.6 days (mean = 7.1 days). One hundred eighty-eight of 202 (93.1%) were completed laparoscopically. Fourteen (6.9%) were converted. The overall morbidity rate was 15.8%. There were three clinically apparent anastomotic leaks. The 30-day mortality was 1 (0.5%). The mean nodal yield was 13.4 (range = 8-37) nodes. There were no positive margins detected. Overall survival in laparoscopically treated colon cancer was 88.1%. In those patients with non-metastatic disease, the overall survival was 90.7% (165/182). CONCLUSION Laparoscopic resection for colon cancer is achievable in 85% (188/222) of patients. This facilitates adequate oncological clearance. It is associated with a low morbidity rate and favourable short-term survival outcomes. This data reflects the potential outcomes dedicated MIS colorectal units will have to offer colon cancer patients once laparoscopic colorectal surgery becomes the de facto surgical approach.

Abstract
AIM We analysed the outcome of a consecutive series of 500 unselected patients who underwent elective laparoscopic colorectal resection with anastomosis (ELCRA) under the care of a single surgeon. METHOD A prospectively collected electronic database of all laparoscopic procedures conducted from April 2001 to September 2008 was analysed. RESULTS A total of 500 ELCRAs were performed [230 male and 270 female patients; mean age 65.6 years (range 19-93 years; American Society of Anesthesiologists grade I (103), II (246), III (145) and IV (6)]. Of these, 217 patients underwent high anterior resection. A total of 131 total mesorectal excisions (55 covering ileostomies), 152 right/extended right resections and 240 operations were performed by trainees under supervision. The indications for surgery included cancer (340), diverticular disease (96), Crohn's disease (40) and polyps (24). Mean operating time was 115 min (range 35-550 min). There were eight (1.6%) conversions. The mean length of hospital stay was 5.2 days (median 4 days). A total of 93 (18.6%) patients had an inpatient complication, including ileus (22), wound infection (14), anastomotic leakage (12), enterotomy (2), 'off-screen' enterotomy (2), abscess (3), ureteric injury (1), cardiac arrhythmia (12), myocardial infarction (5), pulmonary embolus (4), pneumonia (1), Clostridium difficile (3) and retention of urine (9). There were 20 (4%) readmissions for complications, including ileus (4), urinary retention (3), abscess formation (2) and leakage (2). The 30-day mortality was nine of 500 (1.8%) following anastomotic leakage (3), duodenal enterotomy (1), bleeding duodenal ulcer (1), C. difficile infection (1) and cardiac complications (3). CONCLUSION This unselected cohort of patients (the largest single surgeon series in the UK) demonstrates that in trained hands low conversion and complication rates can be consistently achieved.

Metaanalysis of trials comparing minimally invasive and open distal pancreatectomies. Surg Endosc 2010; 25:1642-51. [PMID: 21184115 DOI: 10.1007/s00464-010-1456-5] [Citation(s) in RCA: 112] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2010] [Accepted: 10/19/2010] [Indexed: 02/05/2023]
Abstract
BACKGROUND The current literature suggests that minimally invasive distal pancreatectomy (MIDP) is associated with faster recovery and less morbidity than open surgery. However, most studies have been limited by a small sample size and a single-institution design. To overcome this problem, the first metaanalysis of studies comparing MIDP and open distal pancreatectomy (ODP) has been performed. METHODS A systematic literature review was conducted to identify studies comparing MIDP and ODP. Perioperative outcomes (e.g., morbidity and mortality, pancreatic fistula rates, blood loss) constituted the study end points. Metaanalyses were performed using a random-effects model. RESULTS For the metaanalysis, 10 studies including 349 patients undergoing MIDP and 380 patients undergoing ODP were considered suitable. The patients in the two groups were similar with respect to age, body mass index (BMI), American Society of Anesthesiology (ASA) classification, and indication for surgery. The rate of conversion from full laparoscopy to hand-assisted procedure was 37%, and that from minimally invasive to open procedure was 11%. Patients undergoing MIDP had less blood loss, a shorter time to oral intake, and a shorter postoperative hospital stay. The mortality and reoperative rates did not differ between MIDP and ODP. The MIDP approach had fewer overall complications [odds ratio (OR), 0.49; 95% confidence interval (CI), 0.27-0.89], major complications (OR, 0.57; 95% CI, 0.34-0.96), surgical-site infections (OR, 0.32; 95% CI, 0.19-0.53), and pancreatic fistulas (OR, 0.68; 95% CI, 0.47-0.98). CONCLUSIONS The MIDP procedure is feasible, safe, and associated with less blood loss and overall complications, shorter time to oral intake, and shorter postoperative hospital stay. Furthermore, the minimally invasive approach reduces the rate of pancreatic leaks and surgical-site infections after ODP.

Abstract
BACKGROUND AND OBJECTIVES The excellent outcomes reported for laparoscopic colorectal surgery in selected patients could also be potentially advantageous for high risk patients. This prospective study was designed to examine the feasibility and safety of laparoscopic resection in high risk patients with colorectal cancer. METHODS Between 2006 and 2008 consecutive patients undergoing elective surgery for colorectal cancer were stratified into high and low risk groups. High risk was defined as >or=80 years, American Society of Anesthesiologists >or=3, preoperative radiotherapy, T4 tumor and BMI >or=30. Outcomes included median length of stay, lymph node yield, resection margins, 30-day hospital readmission, postoperative mortality and major postoperative complications requiring reoperation within 30 days of surgery. RESULTS A total of 424 patients underwent elective laparoscopic (224) and open (200) resections. Overall mortality rate for laparoscopic resection was 1 of 224 (0.4%) versus 4 of 200 (2%) for open resection. Median length of stay was 4 (2-33) versus 10 (1-69) days (P < 0.0001), and rate of complications requiring reoperation was 2 of 224 (0.8%) compared with 10 of 200 (5%) (P = 0.02).Among the 280 (66%) "high risk" patients, 146 had laparoscopic resection (8 conversions; 5%) and 134 had open resections. Median hospital stay was 4 (2-33) days in the laparoscopic group versus 11 (1-69) days in the open group (P < 0.0001). Complications requiring reoperation were 2 of 146 (1.4%) after laparoscopic resection versus 7 of 134 (5.2%) after open resection (P < 0.09). Readmission rate after laparoscopic resection was 12.3% versus 5.2% after open resection (P = 0.06). CONCLUSION Laparoscopic resection of colorectal cancer can achieve excellent results even in "high risk" patients and is associated with significant reductions in length of stay compared with open resection.

Abstract
The minimally invasive technique, by means of the undoubted advantages of the method, has become fully accepted in the surgical treatments of the most benign and functional diseases. Today it has been proven that the laparoscopic technique is safely usable also in the surgical treatment of colorectal tumors. The authors, analyzing their own and the international experiences, present the laparoscopic surgical treatment of colorectal tumors. Seventy-four patients were treated with laparoscopic-assisted colorectal intestinal resection in the Department of Surgery of the University of Szeged between January 1, 2005 and December 31, 2008. The surgical indication was neoplastic colorectal lesion in 40 cases. The average age of them was 64 years (from 36 to 89 years). Four patients belonged to the risk group of ASA I, 11 patients to ASA II, 24 to ASA III, and one to ASA IV. Twenty-six patients underwent rectosigmoideal resection, 2 had rectal exstirpation, 9 had right hemicolectomy and one had left hemicolectomy. There were no surgical or postoperative complications. Four conversions and in one case a reoperation occurred due to adhesion ileus. The startup of the passage (2.4 days, on average) and the possibility of nourishing per os were significantly shortened. The histological processes of specimens justified tumor-free oral, aboral and circumferential resection in all cases. Summarizing our own and international experiences it can be stated that the laparoscopic surgeries performed due to colorectal tumors are safe, and are also appropriate with respect to oncosurgery. There are a number of benefits for the patients mainly in the early postoperative period (faster recovery, shorter hospitalization) and their long-term survival results are good as well.

Abstract
INTRODUCTION This study specifically examined right colonic cancer resection, a common operation for colorectal surgeons starting laparoscopic resection, to assess the impact of commencing laparoscopy. PATIENTS AND METHODS A total of 56 patients undergoing open (n = 34) and attempted laparoscopic (n = 22) elective right hemicolectomy for colorectal cancer between November 2003 and March 2007 were compared. Postoperative stay was the primary outcome. Secondary outcomes included analgesic requirements, bowel recovery, morbidity and mortality. Frequency of laparoscopic versus open surgery over time was also examined. RESULTS Resections attempted laparoscopically increased from 9.1% to 75% in the first and last quarters of the study period, respectively (P = 0.0002). Uptake of 'enhanced recovery' was mainly in the laparoscopic group. Conversion was required in two of 22 patients. Attempted laparoscopic cases had a shorter median postoperative stay (6 vs 10 days; P < 0.0001), duration of parenteral or epidural analgesia (48 vs 72 h; P < 0.0001) and time to first bowel action (3 vs 4 days; P = 0.001) compared with open cases. Demography, tumour characteristics, morbidity and mortality were comparable between groups. Multivariate analysis identified decreased age, attempted laparoscopic surgery, use of enhanced recovery and absence of complications as independently shortening postoperative stay. CONCLUSIONS Advantages of laparoscopic surgery and enhanced recovery, even early in a surgeon's experience, suggest this is the preferred mode for elective right colon cancer resection.

Abstract
BACKGROUND Laparoscopic colorectal resection is widely used because of its safety and effectiveness compared with conventional surgery; however, surgical assistants find it difficult to perform this surgery in mirror image. This study aimed to evaluate assistants' learning curves in laparoscopic colorectal surgery. METHODS The subjects were three fellows who began their surgical fellowship training at the Center for Colorectal Cancer of the National Cancer Center, Korea, during 2008. We analyzed the data from 145 laparoscopic colorectal surgeries in which these assistants participated. A learning curve was generated for each assistant using the moving average method to assess the execution time and the error rate for grasping tissue. RESULTS Assistants A, B, and C participated in 50, 45, and 50 laparoscopic colorectal surgeries, respectively. Learning curves indicated that the execution time reached a steady state after 38 cases for Assistant A, 29 cases for Assistant B, and 24 cases for Assistant C. Based on a decline in the error rate, the steady state was reached after approximately 44 cases for Assistant A, 32 cases for Assistant B, and 41 cases for Assistant C. CONCLUSION Analysis of the assistants' learning curves suggests that under reverse alignment conditions, assistants require participation in 30-40 cases before gaining surgical competence. These results have implications for training assistants for laparoscopic colorectal surgery.

Abstract
BACKGROUND The influence of obesity on surgical outcomes after laparoscopic colorectal surgery in Asian patients is unclear. The aim of this study was to evaluate the feasibility and safety of laparoscopic surgery in obese Asian patients with colorectal cancer. METHODS We retrospectively reviewed the prospectively collected data on 984 consecutive patients who underwent laparoscopic surgery for colorectal cancer between May 2001 and February 2008. Patients were classified according to the categories proposed by the International Obesity Task Force, as Nonobese (body mass index [BMI] < 25.0 kg/m(2)), Obese I (BMI 25.0-29.9 kg/m(2)), and Obese II (BMI > or = 30 kg/m(2)). Surgical outcomes, including open conversion, operation time, postoperative complications, estimated blood loss, and postoperative hospital stay, were compared in Nonobese, Obese I, and Obese II patients. RESULTS Of the 984 patients, 645 (65.5%), 312 (31.7%), and 27 (2.7%), were classified as Nonobese, Obese I, and Obese II, respectively. Clinicopathologic characteristics were similar among the three groups. The Obese II group had higher conversion rates (14.8% versus 2.6% and 2.9%, P = 0.001), longer operation time (258 versus 201 and 215 min, P = 0.001), and longer postoperative hospital stay (12.1 versus 9.5 and 9.2 days, P = 0.035) than the Nonobese and Obese I groups. However, the rates of intraoperative events (P = 0.634) and postoperative complications (P = 0.603) were similar in nonobese and obese patients. Independent risk factors for conversion were BMI group and operation type. Obese II patients had an 8.36-fold greater risk of conversion than had Nonobese patients (P = 0.001). CONCLUSIONS With sufficient experience, laparoscopic colorectal surgery in obese Asian patients is feasible and safe, offering all the benefits of a minimally invasive approach. Management of Asian colorectal cancer patients with BMI > or = 30 kg/m(2) requires meticulous perioperative care, and colorectal surgeons must be familiar with obesity-related challenges in such patients.

Abstract
BACKGROUND Pancreatic resection is associated with a significant morbidity. Efforts to reduce hospital stay and enhance recovery have seen the introduction of minimally invasive surgical techniques. This article reviews the current published literature on the safety and efficacy of minimally invasive surgery of the pancreas. METHODS An electronic search of the PubMed and Embase databases was performed from 1996 to May 2008 to identify all relevant publications; studies meeting predefined inclusion criteria were retrieved and analyzed using a standardized protocol. Data on the safety and efficacy of minimally invasive surgery of the pancreas were recorded and analyzed. RESULTS Of 565 abstracts reviewed, 39 studies were identified as eligible for inclusion. There were 37 case series and two case control studies. Compared with open pancreatic surgery, minimally invasive pancreatic resection is similar in terms of morbidity and mortality. Blood loss and length of stay are decreased. CONCLUSIONS Laparoscopic distal pancreatic resection and enucleation of insulinoma appear to be safe procedures with reduced hospital stay, though morbidity remains significant. The evidence for laparoscopic pancreaticoduodenectomy is in its infancy, but the authors feel it is unlikely that many centers will achieve sufficient case load to make the introduction of minimally invasive resection feasible.

Abstract
OBJECTIVE The use of laparoscopic surgery coupled with an enhanced recovery programme (ERP) has resulted in hospital stays of 4 or less days for colonic and 6 days following rectal resection, in previously reported small selected groups of patients. This report analyses an unselected cohort to determine if such benefits are reproducible. METHOD Consecutive patients undergoing elective colonic or rectal surgery at a single centre between January 2002 and January 2006 were followed. All were included in the ERP and underwent either laparoscopic or open surgery. RESULTS The study group comprised 241 patients (mean age of 67 +/- standard deviation 14 years and 49% male sex distribution) who underwent elective colorectal resection within the context of an ERP. One hundred and fifty-one (62.7%) patients had malignant disease. Overall, 191 (79.3%) patients underwent a laparoscopic procedure and the remaining underwent an open operation. Postoperative stay was shorter in patients undergoing laparoscopic vs open, colonic surgery (4 days vs 6 days, P = 0.002). A nonsignificant trend towards reduced postoperative stay was observed for patients undergoing laparoscopic vs open, rectal surgery (6 days vs 9 days, P = 0.088). Patients undergoing laparoscopic colectomy demonstrated significantly lower 30-day mortality rates than those undergoing traditional colectomy (3/131 vs 3/39, P = 0.049). CONCLUSION Laparoscopic colonic surgery in the context of an ERP offers reduced hospital stay and may confer a survival advantage over traditional techniques. These results confirm that previously reported benefits of laparoscopic surgery are reproducible within an unselected population.
