Surgery for fistula-in-ano: an audit of practise of colorectal and general surgeons.

Objective Some conditions, previously managed by general surgeons, may be treated more successfully by colorectal specialists. This argument is well established for rectal cancer but does it also apply to benign conditions? This study compares the treatment strategies and outcomes for fistulae‐in‐ano by general and colorectal surgeons in a district general hospital. Method Patients who had surgery for fistula‐in‐ano from January 1992–October 2003 were identified from theatre records. Case notes were reviewed for data on type of fistula, aetiology, surgery performed and recurrence. All patients were sent a questionnaire requesting details of recurrence and incontinence. The severity of incontinence was assessed using the Faecal Incontinence Quality of Life Scale (FIQOLS) and the Faecal Incontinence Severity Index (FISI). Results Eighty four patients (male = 53) were identified. Colorectal surgeons performed surgery in 34 and general surgeons in 50 patients. These groups were comparable with terms of age, gender, aetiology (colorectal: IBD = 5, cryptoglandular = 21: general IBD = 14, cryptoglandular = 24; P = 0.28; Chi‐squared test), and type of fistulae (colorectal: inter‐sphincteric = 20, trans‐sphincteric = 13: general inter‐sphincteric = 30, trans‐sphincteric = 18: P = 1.0; Fisher's exact test). Colorectal surgeons carried out fewer fistulotomies (47.1%vs 84.0%; P < 0.001; Fisher's exact test), more staged fistulotomies with Setons (44.1%vs 10.0%: P < 0.001; Fisher's exact test), and had fewer recurrences (9.7%vs 30.0%: P < 0.05; Fisher's exact test) when compared with general surgeons. Five patients with recurrence from the general surgery group were subsequently referred to the colorectal surgeons; four patients had further surgery (fistulotomy = 2; staged fistulotomy = 2) with no recurrence to date; one patient required proctectomy. Forty seven (64.4%) patients answered the questionnaire. There was no difference between patients operated on by colorectal or general surgeons with regards the frequency (43.5%vs 62.5%: P = 0.25; Fisher's exact test) or severity [FISI 26 (21–38); median (inter‐quartile range) vs 26 (17–38); median (inter‐quartile range: P = 0.85; Mann–Whitney test) of faecal incontinence. There was no difference between the groups with regards any of the four scales that comprised the FIQOLS. Conclusions The number of included patients is far too low to draw any conclusions but there were some interesting trends. For similar patient samples, colorectal surgeons seem to adopt a more conservative approach and have fewer recurrences than general surgeons. These differences are not reflected in the frequency or severity of postoperative incontinence.     

Prior abdominal open surgery does not impair outcomes of laparoscopic colorectal surgery: a case–control study in 367 patients

Aim This prospective case‐matched study was conducted to compare the outcome of laparoscopic colorectal surgery in patients with and without prior abdominal open surgery (PAOS). Method From June 1997 to December 2010, 167 patients with PAOS (including midline, Pfannenstiel, subcostal, right upper quadrant or transverse incision) were manually matched to all identical patients without PAOS from our prospective laparoscopic colorectal surgery database. Matching criteria included age, gender, American Society of Anesthesiology (ASA) score, body mass index, diagnosis and surgical procedure performed. Primary end‐points were postoperative 30‐day mortality and morbidity. Secondary end‐points included operating time, conversion rate and length of stay. Results A total of 367 patients (167 with PAOS and 200 without PAOS) were included in this study. PAOS was associated with a significantly increased mean operating time (229 ± 66 min vs 216 ± 71 min, P = 0.044). The conversion rate was significantly higher in patients with PAOS, compared with patients without PAOS (22%vs 13%, P = 0.017). There was one (0.3%) postoperative death. The overall postoperative morbidity rate was similar in both groups (22%vs 19%, P = 0.658), including Grade 3 or Grade 4 morbidity, according to Dindo’s classification (5%vs 5%, P = 0.694). Mean hospital stay showed no difference between both groups (10 ± 7 days vs 9 ± 5 days, P = 0.849). Conclusion This large case–control study suggests that PAOS does not affect postoperative outcomes. For this reason, a systematic laparoscopic approach in patients with PAOS, even with midline incision, should be considered in colorectal surgery.     

Current practice in bowel preparation for colorectal surgery: a survey of the members of the Association of Coloproctology of GB & Ireland

Aim Recent meta‐analyses have suggested that mechanical bowel preparation is not beneficial in patients undergoing colorectal resection. This study aimed to assess current surgical practice in the UK. Method Three hundred and ninety‐eight members of the Association of Coloproctology of GB & Ireland were invited to complete an online survey to ascertain their current practice for bowel preparation. Results One hundred and ninety‐nine surgeons completed the survey, of whom 95 (48%) routinely performed laparoscopic resection. The proportions using full bowel preparation for open vs laparoscopic surgery were, respectively, 9.5%vs 16.8% for right hemicolectomy, 43.4%vs 40.2% for left hemicolectomy, 20.5%vs 22.5% for an abdominoperineal resection and 72.2%vs 63.6% for low anterior resection. Among the surgeons who participated, 13.6% changed their practice between doing the same procedure open and laparoscopically, 76% of surgeons routinely defunctioned a low anterior resection. Of these, 22% did not feel that full bowel preparation was necessary before formation of an ileostomy. Conclusion The study demonstrates that a large proportion of patients still receive full bowel preparation despite recent advice to the contrary.     

Short‐term and long‐term outcomes of patients with malignant large bowel obstruction

Objective: The aim of the present study was to review our experience in the surgical management of patients with obstructing colorectal cancers over an 11‐year period, 1987–1997. Patients and methods: Retrospective review of case records of 275 patients (male: 177; female 98) who had undergone emergency surgery for obstructing colorectal cancers was performed. Tumours proximal to splenic flexure were defined as proximal tumours while those at or below the splenic flexure were defined as distal tumours. Results: The obstruction was caused by proximal tumours in 88 (32%) patients. The resection rate and the primary anastomotic rate were higher for proximal tumours compared with distal tumours (95.5%vs 85.6%, P = 0.014; 92%vs 30.5%, P < 0.001). For distal tumours, stoma rate was found to be influenced by the following factors: preoperative albumin level, duration of observation after admission, operating surgeons’ years of experience, bowel perforation and site of the obstructing tumour. Multivariate analysis disclosed that surgeons’ experience was the only independent factor predicting stoma formation. The in‐hospital mortality and the anastomotic leakage rates were 15.3% and 5.6%, respectively. Tumour stage was the only prognostic factor affecting the disease‐free survival after curative resection. The 5‐year disease‐free survival rates for Dukes’ B and C disease were 66% and 37.2%, respectively. Conclusions: Tumour stage was a significant prognostic factor for patients with obstructing colorectal cancers. Emergency surgery for distal tumours should preferentially be performed by more experienced surgeons in order to achieve a higher anastomotic rate.     

The contemporary management of haemorrhoids

Background New concepts in the management of haemorrhoidal disease have recently rekindled interest in this common pathology. General and subspecialist colorectal surgeons were surveyed to assess their impact on the current management of haemorrhoids. Methods A questionnaire was sent to all members of the Association of Coloproctology of Great Britain and Ireland (ACPGBI) and the Association of Surgeons of Great Britain and Ireland (ASGBI). Regarding indications for surgery, surgical techniques, day case haemorrhoidectomy (DCH) and postoperative treatment regimens. ASGBI members were asked to state their subspecialist interest and estimated time devoted to colorectal practice. Results There were 406 (71%) ACPGBI respondents and 483 (68%) ASGBI respondents. Eighty‐four (12%) ASGBI respondents performed no elective colorectal surgery. One hundred and ninety‐nine (35%) of ACPGBI respondents saw between 6 and 10 new haemorrhoid patients per week whereas three hundred (42%) of ASGBI respondents saw between 1 and 5 per week. Non‐operative management included routine advice on fluid and diet by the majority of surgeons, with banding carried out in 79% (ACPGBI) and 75% (ASGBI) and injection sclerotherapy in 61% (ACPGBI) and 56% (ASGBI). The Milligan Morgan haemorrhoidectomy was performed in 265 (46%; ACPGBI) and 336 (47%; ASGBI). ACPGBI members used Submucosal diathermy (148, 26%vs 67, 9%; ASGBI (P < 0.01; χ² test with Yates correction)) and stapled anoplasty (61, 11%vs 14, 2%; ASGBI (P < 0.01; χ² test with Yates correction)) more often. DCH was performed in 117 (20%; ACPGBI) and in 48 (7%; ASGBI)(P < 0.01; χ² test with Yates correction). Conclusions In this sample of surgeons, operative management varies according to specialist interest. There was a trend towards day case haemorrhoidectomy. Whilst more surgeons have accepted the use of postoperative techniques to reduce pain, only a small minority have, as yet, adopted new surgical techniques such as stapling.     

Laparoscopy in the surgical treatment of rectal cancer in Germany 2000–2009

Aim The goal of this registry study was to compare open surgery with planned laparoscopy and then with laparoscopic to open conversion for rectal cancer surgery. Method The study included 17 964 rectal cancer patients, operated on between 1 January 2000 and 31 December 2009, from 345 hospitals in Germany. All statistical tests were two‐sided, with the χ² test (Pearson correlation) for patients and tumour characteristics. Fisher’s exact test was used for complications and 30‐day mortality. Results Of the 17 964 rectal cancer patients, 16 308 (90.8%) had an open procedure and 1656 (9.2%) were started with a laparoscopy. The 1455 patients with completed laparoscopic operations had fewer intra‐operative and postoperative complications (5.4%vs 7.0%, P = 0.020, and 20.5%vs 25.8%, P < 0.001, respectively) and a lower 30‐day mortality rate (1.1%vs 1.9%, P = 0.023). Of the 1656 planned laparoscopies, 201 (12.1%) were converted to open. The converted group suffered more intra‐operative complications (18.9%vs 3.6% for completed laparoscopy and 7.0% for open surgery, P < 0.0001) and postoperative complications (32.3%vs 18.9% for completed laparoscopy and 25.8% for open operations, P < 0.0001). The converted group also had a higher 30‐day mortality rate (2.0%vs 1.0% for completed laparoscopy and 1.9% for open surgery, P = 0.043). Conclusion The more favourable patient profile provided justification for a laparoscopic procedure. For those converted to an open procedure, however, there were significantly more complications than planned open surgery patients. A move away from the standard open procedure for rectal cancer surgery and towards laparoscopy is not yet feasible.     

Current attitudes in laparoscopic colorectal surgery

Background: In this study, we set out to examine the current attitudes among surgeons toward laparoscopic colorectal surgery (LCS). Methods: A total of 3628 questionnaires were sent to all North American members of the Society of American Gastrointestinal Endoscopic Surgeons (SAGES) and the American Society of Colon and Rectal Surgeons (ASCRS); 40% of the members of each society responded (B15 respondents). Results: Currently, 85% of the respondents perform laparoscopic surgery; LCS was performed by 48% of the respondents in 21% of their patients. Although 35% of the members of SAGES have increased the number of laparoscopic colorectal operations they perform in the last 3 years, only 26% of ASCRS members did so. Our findings showed that 74% of the surgeons who perform LCS do so for diverticular disease, 68% for colonic polyps, 61% for villous adenoma, and 36% for ileal Crohn's disease. However, only 15% operate for the cure of carcinoma of any stage (16% of SAGES members and 11% of ASCRS members), whereas 8.5% and 7% operate for the cure of all upper and lower rectal carcinomas, respectively. Thirty-six percent of the surgeons who perform LCS for cancer have done between one and 10 curative resections, 8% have done 11–20 procedures, and 14% have done >20 procedures. There were 80 cases of port site recurrence reported by 4.4% of surgeons. Although 56% of the respondents would themselves undergo laparoscopic colorectal surgery for a rectal villous adenoma, only 9% would do so for a distal-third rectal carcinoma (12% of SAGES and 5% of ASCRS respondents). Conclusions: The overall percentage of respondents performing LCS has decreased over the last 3 years; moreover, surgeons are more hesitant to perform laparoscopic surgery for the cure of colonic cancer. Due to the overall low response rate, the fact that 4.4% of those surgeons who did respond have seen port site recurrences does not allow any conclusions to be drawn about the prevalence of this problem.     

Intersphincteric resection for low rectal cancer: laparoscopic vs open surgery approach

Aim Laparoscopic sphincter‐saving surgery has been investigated for rectal cancer but not for tumours of the lower third. We evaluated the feasibility and efficacy of laparoscopic intersphincteric resection for low rectal cancer. Method From 1990 to 2007, patients with rectal tumour below 6 cm from the anal verge and treated by open or laparoscopic curative intersphincteric resection were included in a retrospective comparative study. Surgery included total mesorectal excision with internal sphincter excision and protected low coloanal anastomosis. Neoadjuvant treatment was given to patients with T3 or N+ tumours. Recurrence and survival were evaluated by the Kaplan–Meier method and compared using the Logrank test. Function was assessed using the Wexner continence score. Results Intersphincteric resection was performed in 175 patients with low rectal cancer: 110 had laparoscopy and 65 had open surgery. The two groups were similar according to age, sex, body mass index, ASA score, tumour stage and preoperative radiotherapy. Postoperative mortality (zero) and morbidity (23%vs 28%; P = 0.410) were similar in both groups. There was no difference in 5‐year local recurrence (5%vs 2%; P = 0.349) and 5‐year disease‐free survival (70%vs 71%; P = 0.862). Function and continence scores (11 vs 12; P = 0.675) were similar in both groups. Conclusion Intersphincteric resection did not alter long‐term tumour control of low rectal cancer. The safety and efficacy of the laparoscopic approach for intersphincteric resection are suggested by a similar short‐ and long‐term outcome as obtained by open surgery.     

Apical node metastasis independently predicts poor survival in Dukes C colorectal cancer

Aim The prognostic significance of apical node metastasis in node‐positive colorectal cancer (CRC) is disregarded by the Fourth American Joint Committee on Cancer and the International Union Against Cancer (AJCC/UICC) TNM classification system. The influence of apical node metastases on overall 5‐year survival among patients with Dukes stage C CRC was examined. Method Patients who underwent operative resection for CRC between 1999 and 2003 were reviewed. Results Two‐hundred and ninety patients were included in the study, including 203 with Dukes C apical node‐negative cancers, 39 with Dukes C apical node‐positive cancers and 48 with Dukes D cancers. The respective prevalence of extramural vascular invasion was 35%vs 64%vs 56% (P = 0.0005), T4‐stage 24%vs 38%vs 48% (P = 0.013), positive resection margin 16%vs 41%vs 23% (P = 0.001), more than three positive nodes harvested 28%vs 85%vs 52% (P < 0.0001) and poorer tumour differentiation grade 9%vs 21%vs 23% (P = 0.009). Multivariate analyses of all Dukes C cancer patients (n = 242) showed a positive apical node to be a highly significant independent predictor of mortality (hazard ratio 2.281, 95% confidence interval 1.421–3.662, P = 0.0006). Extramural vascular invasion and a positive resection margin were also independent predictors of poor survival. Patients with Dukes C apical node‐positive cancers had a significantly poorer overall 5‐year survival compared to patients with Dukes C apical node‐negative cancers (P < 0.0001) but survival was not significantly different compared to patients with distant metastases at initial presentation (P = 0.504). Conclusion Apical node metastasis appears to be a strong independent, negative prognostic factor of poor survival in Dukes C CRC.     

Laparoscopic total colectomy and ileorectal anastomosis (IRA), supported by an enhanced recovery programme in cases of familial adenomatous polyposis

Aim Familial adenomatous polyposis (FAP) is associated with an almost 100% chance of colorectal cancer by the age of 50 years. Surgery is the only prophylaxis. The study compared the outcome of prophylactic laparoscopic colectomy and ileorectal anastomosis (IRA) with conventional open surgery. Method A case–control study was carried out including all cases of proven FAP undergoing prophylactic laparoscopic colectomy with IRA between 1 April 2006 and 31 March 2008 using a standardized technique within an enhanced recovery programme (ERAS). All data were collected prospectively. Controls were identified retrospectively from patients who underwent open prophylactic IRA before 31 March 2008 and were matched for age, gender, BMI and ASA. Outcomes included duration of surgery, complications, length of stay, readmission and mortality. Results During the study period 25 patients underwent laparoscopic IRA. The median operating time was longer in the laparoscopic group (235 vs 180 mins, P < 0.0001) but the median hospital stay was shorter (6 vs 9 days, P = 0.002). Overall there were fewer complications in the laparoscopic group (20%vs 40%, P = 0.3). Conclusion Laparoscopic prophylactic colectomy with IRA in FAP is safe and feasible, and combined with ERAS leads to accelerated recovery and possibly fewer complications than open surgery. FAP patients undergoing prophylactic IRA should be offered laparoscopic surgery.     

The differences between American and Chinese patients with Crohn’s disease

Aim The effect of race on Crohn’s disease (CD) remains uncertain. This study compared the characteristics of American white patients and Chinese patients with CD. Method A retrospective chart review was conducted for patients who required management of colorectal CD between 1985 and 2004 at either Cleveland Clinic Florida (CCF) or at the 301 Hospital in China. Data included a family history of CD, smoking history, location of the CD and histopathology. Results The mean age of onset in the 153 patients was 29.8 ± 16.4 years for American white patients and 32.4 ± 15.3 years for Chinese patients (not significant). Sixty per cent of American white patients were women vs 37% of Chinese patients (P = 0.003). Twelve per cent of American white patients vs 1% of Chinese patients had a family history of CD (P = 0.016). American white patients had significantly higher rates of arthritis (32%vs 4%), abscess (19%vs 0%), rectal and perineal fistula (52%vs 0%), and disease involving the colon and rectum when compared with Chinese patients (all P < 0.05). American white patients had more colorectal sites involved and higher rates of extraintestinal diseases (40%vs 20%) than Chinese patients (all P < 0.05). Chinese patients had higher rates of ileocaecal disease (82%vs 52%) and deep ulcers (66%vs 24%) in the colorectum (all P < 0.001). There were no statistical differences in the incidence of smoking, perforation, intra‐abdominal fistula, stenosis, bowel obstruction, toxic megacolon or granuloma formation. Conclusion This study found that colorectal CD had a more severe clinical presentation and pathological involvement in American white patients than in Chinese patients.     

The impact of evolving management strategies on negative appendicectomy rate

Aim The management of appendicitis has evolved from the era of open surgery with a negative appendicectomy rate ranging from 20 to 30%. Diagnostic adjuncts such as computed tomography (CT), ultrasound (US) and diagnostic laparoscopy (DL) facilitate refinement of the clinical impression in equivocal cases. The aim of this study was to determine the impact of the increased availability and selective utilization of diagnostic adjuncts on the negative appendicectomy rate. Method This was a retrospective study of all emergency appendicectomy procedures performed over two 12‐month periods encompassing 1996 and 2006. Clinical, radiological, operative and pathological data were analysed. Diagnostic adjuncts were only employed in equivocal cases. Statistical analysis was performed using the chi‐squared test. Results A total of 218 and 171 patients underwent an appendicectomy in 2006 and 1996 respectively. There were 103 men in 1996 and 128 in 2006. There was a significant increase in laparoscopic appendicectomy [131(60%) vs 31 (18%), P > 0.001]. In addition, there was a significant increase in the use of CT (38 vs 1, P < 0.001) and US (39 vs 4, P < 0.001).There was also a significant difference in the use of DL without appendicectomy (39 vs 8, P < 0.001). The negative appendicectomy rate was lower in 2006 (15%vs 22%, P = 0.13).The perforation rates in both study periods were similar (10%vs 8%). Conclusion A policy of selective usage of diagnostic adjuncts only in equivocal cases of appendicitis does not significantly reduce the negative appendicectomy rate.     

Laparoscopic vs transverse incision right colectomy for colon carcinoma

Aim We investigated whether laparoscopic right colectomy has short‐term and/or oncological advantages compared with transverse incision right colectomy. Method Patients who underwent an elective laparoscopic right colectomy or an open right colectomy through a transverse incision at the VU University Medical Center or Zaans Medical Center from 2005 to 2009 were prospectively followed. Results Patient groups were comparable in terms of gender, body mass index and American Society of Anesthesiology classification. Patients in the transverse incision group were older (68 years vs 75 years, P = 0.07) and blood loss was greater during this procedure (60 ml vs 130 ml, P = 0.001), which cost less than the laparoscopic procedure (€6.033 vs€7.221, P = 0.03). Hospital stay for the laparoscopic group was shorter (8 days vs 9 days, P = 0.04), but laparoscopic procedures took longer (155 min vs 77 min, P < 0.001) and 8% of patients in the laparoscopic group were converted to a median laparotomy. Postoperative complications were comparable for both groups (28%vs 32%, P = 0.74), and in both groups a radical resection rate of 96% (P = 0.94) was achieved. At a median follow up of 20 months the incidence of incisional hernia was similar in both groups and no patient required additional surgery as a result. Overall survival at 60 months was 70% for the laparoscopic group and 67% for the transverse incision group (P = 0.84). Conclusion There are few clinically relevant differences between a laparoscopic right colectomy and a transverse incision right colectomy. Transverse incision right colectomy is cheaper. The study may be the first to compare these two techniques, but it is a nonrandomized trial and therefore has its limitations.     

Laparoscopic and open colorectal surgery: a prospective cost analysis

Aim Cost has been perceived to be a factor limiting the development of laparoscopic colorectal surgery. This study aimed to compare the costs of laparoscopic and open colorectal surgery. Method Patients undergoing laparoscopic or open elective colorectal surgery were recruited into a prospective study to evaluate the healthcare costs of each operative procedure in a district general hospital in England. All healthcare resources used (operation, hospital and community) were recorded and converted to costs in British pounds, 2006–2007. Costs of laparoscopic and open surgery were compared. Results In all, 201 consecutive patients consented and were recruited (131 laparoscopic, 70 open). Operative costs were greater in the laparoscopic group (£2049 vs£1263, P < 0.001) due to the costs of disposable instruments, but the hospital costs were less (£1807 vs£3468, P < 0.001) due to longer lengths of stay in the open group. Community costs were similar in the two groups and had little impact on the overall costs, which were not significantly different (£3875 laparoscopic vs£4383 open, P = 0.308). In the subgroup of patients with a stoma, overall costs in the laparoscopic group are higher (not significant). Conclusion The costs of laparoscopic and open colorectal surgery are broadly equivalent. If there is an associated improvement in patient benefit, then laparoscopic colorectal surgery may be considered to be cost effective compared with open surgery.     

Hospital stay amongst patients undergoing major elective colorectal surgery: predicting prolonged stay and readmissions in NHS hospitals

Aim Reduced hospital stay confers clinical and economic benefits for patients and healthcare providers. This article examines the length of stay and consequent bed resource usage of patients undergoing elective excisional colorectal surgery in English NHS trusts. Method All patients undergoing elective colorectal resections for malignancy between 1996 and 2006 in English NHS trusts were included from the Hospital Episode Statistics data set. Unifactorial and multifactorial analyses were performed to identify independent predictors of prolonged stay and 28‐day readmission. Results Over the 10‐year period, 186 013 patients underwent elective colorectal procedures in 181 NHS trusts. About 2.893 million bed days were utilized for elective colorectal surgery. Admission stay was shorter following colonic surgery than following rectal surgery (median 11 vs 13 days, P < 0.001). A 2‐day decrease in median stay was observed over the 10‐year period for both colonic and rectal procedures. Readmissions within 28 days of discharge were higher following rectal excision than following colonic surgery (9.4 vs 7.6%, P < 0.001). Multiple logistic regression analyses revealed the following independent predictors of prolonged hospital stay: distal (vs proximal) bowel resection, benign pathology, open technique, increasing age, comorbidity, social deprivation and low provider volume status. Independent predictors of 28‐day readmission included distal bowel resection, benign diagnosis, young age, social deprivation and high provider volume status. Conclusion Patients of advanced age, with associated comorbidities, and those living in areas of social deprivation are at increased risk of prolonged stay. Targeted pre‐emptive discharge planning and enhanced use of laparoscopic surgery could improve bed resource utilization.     

Who Should Be Doing Laparoscopic Bariatric Surgery?

Background: The training and credentialing of surgeons for laparoscopic bariatric surgery is controversial. We sought to determine if there is an association between surgeons' practice and choice of open or laparoscopic bariatric surgery. Methods: Members of the ASBS were surveyed via email. Associations were tested with Cochran-Mantel-Haenszel or Pearson's chi-square. Results: 104/472 members responded; 65% were in private practice; 47% did 1-5 operations/week, 48% offered open procedures only, and 76% undertook gastric bypass. Respondents believe that laparoscopic procedures: should mimic open ones (77%), are safe (63%), should be evaluated by clinical trials (48%), and that expertise in bariatric surgery is more important than laparoscopic experience. 75% believe that courses and preceptorships are important. Regarding laparoscopic operations, surgeons doing only open procedures believe that: 1) the ASBS should be the main credentialing body; 2) surgeons should do >25 open before laparoscopic ones; and 3) clinical trials are needed (P<0.02, all). Surgeons with laparoscopic training or practices believe that laparoscopic surgery is safe and effective (P<0.002). Both laparoscopic and open surgeons believe bariatric surgeons should be the only surgeons doing laparoscopic bariatric procedures (P<0.008). Conclusions:There is consensus that laparoscopic bariatric surgery should be undertaken only by surgeons with strong interest in bariatric surgery. Laparoscopic bariatric surgeons should incorporate lessons learned from open surgery. Both laparoscopic and open bariatric surgeons should seek added expertise via courses and preceptorships.The skepticism of surgeons with 'open' practices could be addressed by clinical trials. The ASBS should maintain its leadership position and foster emerging technologies.     

Optimal teaching environment for laparoscopic ventral herniorrhaphy

The introduction of laparoscopic techniques after residency training has created a new paradigm dependent on laparoscopic workshops. This study tested the benefit of an animate course and evaluated the role of proctoring in learning to perform laparoscopic ventral hernia repair (LVHR). Surgeons who had taken a 1-day LVHR course (n=59) were polled to determine previous experience with laparoscopic procedures and experience with LVHR after the course. Forty-eight (81%) surgeons completing the course responded. Thirty-two (67%) surgeons had performed 179 LVHRS (mean 5.6) since the course. There were no statistically significant differences between the groups performing and not performing LVHR regarding academic/private practice (P=0.8) or opportunities to perform a ventral herniorrhaphy (P=0.6). Fifteen (31%) surgeons were precepted in their hospital operating room by the lead author. Thirteen (87%) of precepted surgeons had performed a LVHR compared with 19 (58%) of the 33 surgeons taking the course without a precepted intervention (P=0.05). Surgeons with experience performing laparoscopic inguinal hernia repair, Nissen fundoplication, and common bile duct exploration were more likely to perform LVHR (P=0.0001). Surgeons performing only laparoscopic cholecystectomy tended to be less likely to perform LVHR, nearing statistical significance (P=0.08). Surgeons with prior advanced laparoscopic surgery experience are thus more likely to perform LVHR after participating in a 1-day course. Surgeons precepted in their hospital operating room were also more likely to perform LVHR. Participation in an animate laboratory and a precepted experience can impact the future performance of advanced laparoscopic surgery. Electronic Publication     

Stress and burnout among colorectal surgeons and colorectal nurse specialists working in the National Health Service

Background It has been suggested that changes to the organization of the National Health Service (NHS) and clinical practices in dealing with cancer are associated with increased stress and burnout in healthcare professionals. The aim of this study, therefore, was to evaluate stress and burnout in colorectal surgeons (surgeons) and colorectal clinical nurse specialists (nurses) working in the NHS. Method A list of all consultant surgeons and nurses was obtained from The Association of Coloproctology of Great Britain and Ireland. Participants were sent a questionnaire booklet consisting of standardized measures [General Health Questionnaire (GHQ), Maslach Burnout Inventory (MBI), Coping Questionnaire] and various ad hoc questions to obtain information about demographics, cancer workload and job satisfaction. Independent predictors of clinically significant distress and burnout were identified using logistic regression. Results Four hundred and fifty‐five surgeons and 326 nurses were sent booklets. The response rate was 55.6% in surgeons and 54.3% in nurses. The mean age of the nurses was lower than that of surgeons (42.8 vs 47.7, P < 0.001). Psychiatric morbidity was similar in the surgeons and nurses as assessed using the GHQ (30.2% and 30.3% respectively). On the MBI, compared with nurses, surgeons had significantly higher levels of depersonalization (17.4%vs 7.4%, P = 0.003) and lower personal accomplishment (26.6%vs 14.2%, P = 0.002). Seventy‐seven per cent of surgeons and 63.4% of nurses stated their intention to retire before the statutory retirement age. Coping strategies, especially those in which respondents isolated themselves from friends and family, were associated with higher psychiatric morbidity and burnout. Dissatisfaction with work, intention to retire early, intention to retire as soon as affordable and poor training in communication and management skills were also significantly associated with high GHQ scores and burnout in both groups. Discussion We found high levels of psychiatric morbidity and burnout in this national cohort of surgeons and nurses working in the NHS. However, psychiatric morbidity and burnout were unrelated to cancer workload. Nurses have lower burnout levels than surgeons and this may be related to their different working practices, responsibilities and management structure.     

Underlying functional bowel disorder may explain patient dissatisfaction after haemorrhoidal surgery

Aim The aim of this study was to assess patient dissatisfaction and functional symptoms following haemorrhoid surgery, aspects of which are seldom covered in other published series. Method A self‐administered questionnaire was mailed to 359 consecutive patients (prospective database; 198 men, 161 women; median follow up, 59 [1–120] months) who underwent either Milligan‐Morgan haemorrhoidectomy (n = 205) or stapled haemorrhoidopexy (n = 154). Results The response rate was 72%; 2.4% of patients had no opinion, 13.6% were dissatisfied, 33.0% were satisfied, and 51.0% were very satisfied with the treatment. Dissatisfied patients were more likely to be women and more likely to have a long history of constipation and irritable bowel syndrome. The duration of surgery and the rates of pre‐ and postoperative complications did not differ between groups. Residual bleeding (49%vs 32%), prolapse (67%vs 31%) and pain (91%vs 55%) occurred more frequently in the dissatisfied group compared with the satisfied group (P < 0.001). Incontinence (4 [0–16] vs 1 [0–15]; P = 0.0003) and constipation (19 [1–34] vs 8 [0–31]; P < 0.0001) scores were significantly higher in the dissatisfied group compared with satisfied patients. Anal pain was the predominant symptom associated with dissatisfaction in a logistic regression model. Conclusion Persistent pain remains the major long‐term factor associated with dissatisfaction after surgery for haemorrhoids.     

The impact of lymph node yield on Duke’s B and C colorectal cancer survival

Aim The number of positive lymph nodes retrieved following colorectal cancer (CRC) resection impacts on the staging and further treatment of the disease. We compared 5‐year survival by lymph node yield for Duke’s B and C patients to assess the impact on prognosis. Method A retrospective methodology was employed to review patients who underwent operative resection for Duke’s B or C CRC between 1999 and 2003. Results A total of 351 patients were included in our analyses. Lymph node yield, N‐stage and extramural vascular invasion were independent predictors of overall 5‐year survival. A significant difference in 5‐year survival by lymph node yield was seen among Duke’s B patients (< 9 nodes vs≥ 9 nodes, 45.2%vs 68.4%; P = 0.0043) and Duke’s C patients (< 10 nodes vs≥ 10 nodes, 25.6%vs 48.8%; P = 0.0099). There was a significant reduction in the relative risk of 2.8% in mortality for each additional node sampled in Duke’s B and C patients (RR 0.972, 95% confidence interval 0.949–0.994, P = 0.0102). Duke’s B patients who had < 9 lymph node yield and no neoadjuvant/adjuvant treatment had a similar survival to all Duke’s C patients (47.8%vs 41.7%, P = 0.5136). Conclusion Lymph node yield independently predicts for survival in patients with Duke’s B and C CRC. Duke’s B patients with < 9 lymph node yield have no better survival than patients with Duke’s C disease. Therefore, prospective randomized studies are required to examine if inadequate lymph node yield could be one of the deciding factors in offering adjuvant therapy among Duke’s B cancer patients.
