Laparoscopic Colorectal Surgery Outcomes Improved After National Training Program (LAPCO) for Specialists in England.

OBJECTIVE: To examine the impact of The National Training Program for Lapco on the rate of laparoscopic surgery and clinical outcomes of cases performed by Lapco surgeons after completion of training. SUMMARY OF BACKGROUND DATA: Lapco provided competency-based supervised clinical training for specialist colorectal surgeons in England. METHODS: We compared the rate of laparoscopic surgery, mortality, and morbidity for colorectal cancer resections by Lapco delegates and non-Lapco surgeons in 3-year periods preceding and following Lapco using difference in differences analysis. The changes in the rate of post-Lapco laparoscopic surgery with the Lapco sign-off competency assessment and in-training global assessment scores were examined using risk-adjusted cumulative sum to determine their predictive clinical validity with predefined competent scores of 3 and 5 respectively. RESULTS: One hundred eight Lapco delegates performed 4586 elective colo-rectal resections pre-Lapco and 5115 post-Lapco while non-Lapco surgeons performed 72,930 matched cases. Lapco delegates had a 37.8% increase in laparoscopic surgery which was greater than non-Lapco surgeons by 20.9% [95% confidence interval (CI), 18.5-23.3, P < 0.001) with a relative decrease in 30-day mortality by -1.6% (95% CI, -3.4 to -0.2, P = 0.039) and 90-day mortality by -2.3% (95% CI, -4.3 to -0.4, P = 0.018). The change point of risk-adjusted cumulative sum was 3.12 for competency assessment tool and 4.74 for global assessment score whereas laparoscopic rate increased from 44% to 66% and 40% to 56%, respectively. CONCLUSIONS: Lapco increased the rate of laparoscopic colorectal cancer surgery and reduced mortality and morbidity in England. In-training competency assessment tools predicted clinical performance after training.

Use of a robotic camera holder (FreeHand®) for laparoscopic appendicectomy.

Introduction: Use of a mechanical arm to hold the laparoscopic camera has many advantages. FreeHand® (FreeHand Ltd, Guildford, United Kingdom) is a robotic camera holder which uses head movement and infrared technology. This trial assessed the usefulness of FreeHand® in laparoscopic appendicectomy.Material and methods: This was a single center prospective cohort study on patients undergoing emergency laparoscopic appendicectomy using FreeHand®. Patient demographics, operative details, conversion to human camera holder and surgeon discomfort were recorded. Utilization of assistant time while not assisting was also recorded.Results: Twenty-two participants were included, with a mean age of 32 years and a mean BMI of 25.3. The mean set up time was nine minutes. There were five conversions to a manual camera holder (22.7%). There were 22 lens cleaning episodes with nine (40.9%) not requiring any lens cleaning and six (27.3%) requiring one clean. There were no peri-operative complications. Most surgeons reported minimal or no discomfort. Assistant's time was used for ward work (57%), clerking patients (36%) and for a break (7%).Conclusions: FreeHand® can be safely used in laparoscopic appendicectomy. It provides a stable image, puts the surgeon in control of the surgical field, causes minimal user discomfort, and frees up personnel.

Rate of skill acquisition in the use of a robotic laparoscope holder (FreeHand(®)).

BACKGROUND: Robotic equipment can greatly add to the ergonomics of a surgical procedure and pre-operative simulation can provide risk-free training of the surgeon leading to precision surgery and less trauma to the patient. Freehand(®) is a second-generation robotic camera-holding device, which has recently become available to laparoscopic surgeons. It is controlled by the operator selecting a direction using head movement followed by activation with a foot pedal. The purpose of this study was to assess the rate of skill acquisition in the use of the FreeHand(®) robotic laparoscope holder by a group of laparoscopic surgeons by enrolling them into a programme of training modules at The ICENI Centre, Colchester Hospital University, UK. MATERIAL AND METHODS: Twenty surgical registrars performed a series of exercises, escalating in difficulty, to test their skill in controlling the FreeHand(®) robot. Subjective and objective assessments were evaluated by an observer and by tracking analysis software created for this trial. RESULTS: The observed number of head movements showed a Percentage Performance Score (PPS) of 98% by the end of the third repetition of all exercises, the mean Total Head Movements Score (HMS) reached a plateau of performance at 72%. Fifty per cent of the participants selected 'Effective control of movements without difficulty' in the subjective evaluation by the end of the third repetition of exercises, while 35% selected 'competent intuitive movements'. CONCLUSION: The FreeHand(®) robotic laparoscope holder is a useful device, which is easy to operate and requires a very short course of training to achieve competence in its use.

Enhanced recovery program following colorectal resection in the elderly patient.

BACKGROUND: The enhanced recovery program (ERP) aims to reduce the metabolic response to surgery, hastening recovery and shortening hospital stay. Concerns exist regarding morbidity and hospital stay in elderly patients. The present study aimed to compare the outcomes and compliance of elderly patients managed by an ERP protocol with a younger group. METHODS: A review was performed of a prospective database of patients undergoing colorectal resection managed under the ERP protocol between 2005 and 2010. Patients were grouped into <80 years and ≥ 80 years, and perioperative data were collated. The postoperative outcomes were compared with the goals set out by the ERP protocol. RESULTS: A total of 688 patients were included, 558 were <80 years (median: 66 years; range: 17-79 years) and 130 were ≥ 80 years (median: 83 years; range: 80-95 years). Some 96% of operations were planned laparoscopically. Median total length of hospital stay was 6 days (range: 1-108 days) for the <80 year group and 8 days (range: 1-167 days; P 0.363) for the elderly group, with a 30 day readmission rate of 8.6% for the population and no significant differences between groups. The 30 day mortality was 5%, with a significant difference between the two groups (P < 0.0001). Differences in protocol adherence were identified in the discontinuation of intravenous fluids, catheter removal, and early mobilization. CONCLUSIONS: An enhanced recovery program is feasible for colorectal surgery patients ≥ 80 years of age, with similar compliance as the younger group to some aspects of the protocol and an acceptable readmission rate. Attention to improving compliance in the postoperative phase is necessary, particularly in such high-risk patients, as such improvement may reduce the morbidity and mortality.

Chronic groin pain following inguinal hernia repair in the laparoscopic era: Systematic review and meta-analysis.

BACKGROUND: The impact of laparoscopic inguinal hernia repair (IHR) on chronic groin pain (CGP) prevalence, risk and daily activities compared to open IHR is still unclear. METHODS: A meta-analysis of randomised controlled trials comparing CGP rates in laparoscopic and open IHR was performed. RESULTS: 22 trials were included. CGP prevalence decreases significantly 1-2 years post-op and reaches rates as low as 4.69% (laparoscopic) and 6.91% (open) at >5 years. There is a significantly lower risk of CGP following totally extraperitoneal (TEP) than open mesh repair at all follow-up periods (p < 0.05) except for >5 years (p = 0.32). The same trend is not seen when compared to open non-mesh repair or for transabdominal pre-peritoneal repair (TAPP). There is no difference between techniques when CGP is described as moderate and/or affecting daily activities (p = 0.08). CONCLUSION: CGP rates continue to decrease at >5 years follow up. TEP consistently results in a reduction in CGP rates compared to open mesh repair however, this is not functionally significant.

Laparoscopic total mesorectal excision following long course chemoradiotherapy for locally advanced rectal cancer.

PURPOSE: Laparoscopic total mesorectal excision (TME) of locally advanced rectal cancer after long-course chemoradiotherapy (LCRT) is surgically and oncologically challenging. We have assessed the feasibility, timing, and short-term oncological outcome of laparoscopic TME after LCRT. METHODS: Between 2004 and 2006, 30 patients were selected for LCRT based on clinical examination and MRI. Patients received 3/4 field radiotherapy, 45-50.4 Gy in 25-28 fractions during 5 weeks with either 5-fluorouracil or Uftoral. Clinical assessments were made 4 weeks after completion of radiotherapy and then 2 weekly with sequential 4 weekly MRI, to individualize the timing of surgery at maximal response. Laparoscopic TME was performed using a standard technique. RESULTS: Thirty patients received LCRT and 26 patients (21 men; median age, 63 years) underwent laparoscopic TME at 11 weeks (median) after LCRT. Median operating time was 270 min. Sixteen patients had LAR and ten had APR. There were three conversions. Three patients developed anastomotic leak (18.7%): one was managed conservatively and one patient died of septicemia. Morbidity was seen in 19% of patients. There were 25 (96%) R0 resections with a complete response in 5 (19%) cases and microscopic tumor in lakes of mucin (Tmic) in another 6 (23%). Two patients (7.6%) developed local recurrence (median follow up, 34 months). The median time interval between radiotherapy and surgery was 11 (range, 7-13) weeks, which was based on serial MRI scans after LCRT. CONCLUSIONS: Laparoscopic TME after LCRT is feasible and safe both oncologically and surgically. Serial MRI helps to determine the optimum timing of surgery.

Training higher surgical trainees in laparoscopic common bile duct exploration.

BACKGROUND: Laparoscopic common bile duct (CBD) exploration is regarded as a safe, definitive procedure for ductal calculi, avoiding the complications of endoscopic retrograde cholangiopancreatography. We aimed to evaluate the outcomes of laparoscopic CBD exploration carried out by trainees compared to those of an experienced consultant (R.W.M.). METHODS: A prospective database of all cases of laparoscopic CBD exploration over a 15-year period was analyzed retrospectively. All patients underwent a four-port technique and intraoperative cholangiography. Patient demographics, operative technique, success, and complications were analyzed. RESULTS: The median age of patients undergoing laparoscopic CBD exploration was 65 years (range 14-94 years). In all, 187 (79%) of the CBD explorations were performed by one consultant and 48 (21%) by trainees. Calculi were successfully cleared in 141 (88%) and 43 (96%), respectively. There were two (<1%) conversions to an open procedure in the total group. The median operating time was 130 minutes in the consultant group versus 150 minutes in the trainee group (p < 0.05, Mann-Whitney U-test). There was no significant difference in CBD clearance rate, surgical approach, or complication rate between consultant and trainees (Fisher's exact test). CONCLUSIONS: Laparoscopic CBD exploration is a safe procedure in both consultant and trainee hands. With appropriate training, surgical trainees can achieve equivalent outcomes in CBD clearance with no significant difference in complication rates.

Simplified technique for laparoscopic appendectomy.

In this article, a simplified technique for laparoscopic appendectomy is described in which the base of the appendix is firstly divided, and then ligated with an endoloop. An endoloop is then passed over the appendix onto the mesoappendix and tightened to secure the blood supply. The appendix can then be freed and removed. This technique has been used by the authors in difficult cases, and has produced excellent results.

Results of laparoscopic repair of primary and recurrent incisional hernias at a single UK institution.

In this study incisional hernia repairs at a single UK institution between 1994 and 2008 were analyzed with respect to short-term and long-term results. Prospectively collected data were analyzed retrospectively to ascertain outcomes, complications, and recurrences. Two hundred and twenty-seven operations were performed with 35% of the operations being for recurrent hernias. A self-centering suture technique was used. Median operating time was 55 minutes. There were 8 conversions and median hospital stay was 1 night. There were 52 complications (23%) including 3 postoperative bleeds, 3 mesh infections, and 4 small bowel obstructions. Median postoperative follow-up was 53 months. There were 25 recurrences (11%) being detected, a median of 17 months after initial operation. In this large series, laparoscopic incisional hernia repair is safe and is associated with a short hospital stay. Recurrences after repair remain a concern prompting the development of strategies to try and minimize the likelihood of this occurring.

Training in laparoscopic colorectal surgery - experience of training in a specialist unit.

INTRODUCTION: Laparoscopic colorectal surgery, although technically demanding, is an increasingly desirable skill for coloproctologists. We believe that trainees with adequate supervision from an experienced trainer may perform these procedures safely with good outcome. PATIENTS AND METHODS: Surgical logbooks of two senior trainees were reviewed over a 2-year period. A case note analysis was then undertaken. Patient data were recorded with regards to age, sex, operation type, American Society of Anesthesia (ASA) grade, conversion, length of hospital stay and complications. Lymph node yield, resection margins and grade of total mesorectal excision were recorded in oncological procedures. RESULTS: Over the 2-year period, trainees were involved in 140 resections (age range, 23-88 years; ASA grades I-III). Seventy patients were male. Trainees were first assistant in at least 20 cases prior to undertaking the procedures themselves. Trainees performed a total of 71 operations. Median hospital stay was 7 days (range, 2-48 days). There were three conversions. Anastomotic leaks developed in two patients, one requiring a laparotomy. One patient developed small bowel obstruction secondary to a port site hernia, which was repaired laparoscopically. There was one postoperative death. All oncological resection margins were clear with adequate lymphadenectomies. All total mesorectal excisions were Quirke grade III. CONCLUSIONS: Adequately trained and supervised trainees may perform major colorectal resections without compromising outcome.
