The case for standardisation of the management of gallstones spilled and not retrieved at laparoscopic cholecystectomy

INTRODUCTION

This observational study was carried out to establish how surgeons performing laparoscopic cholecystectomy currently deal with the issue of spilled gallstones.

MATERIALS AND METHODS

A questionnaire was circulated amongst laparoscopic surgeons attending the annual conference of the Association of Laparoscopic Surgery of Great Britain and Ireland in November 2006.

RESULTS

Eighty-two surgeons completed the questionnaire. Only half of surgeons inform patients when gallstones are spilled. Less than 30% of surgeons inform general practitioners (GPs) of this complication, when it occurs. Less than a quarter of surgeons include this information in the consent literature provided to patients.

CONCLUSIONS

We recommend that trusts review their policy towards spilled stones either by local audit or adopt the guidance given by the UK Healthcare Commission. While some surgeons feel informing patients and GPs may unnecessarily heighten anxiety from an uncommon complication, our review of the literature suggests this position is not tenable in the current medicolegal climate.     

The impact of surgeon-based ultrasonography for parathyroid disease on a British endocrine surgical practice

INTRODUCTION

Surgeon-based ultrasonography (SUS) for parathyroid disease has not been widely adopted by British endocrine surgeons despite reports worldwide of accuracy in parathyroid localisation equivalent or superior to radiology-based ultrasonography (RUS). The aim of this study was to determine whether SUS might benefit parathyroid surgical practice in a British endocrine unit.

METHODS

Following an audit to establish the accuracy of RUS and technetium sestamibi (MIBI) in 54 patients, the accuracy of parathyroid localisation by SUS and RUS was compared prospectively with operative findings in 65 patients undergoing surgery for primary hyperparathyroidism (pHPT).

RESULTS

The sensitivity of RUS (40%) was below and MIBI (57%) was within the range of published results in the audit phase. The sensitivity (64%), negative predictive value (86%) and accuracy (86%) of SUS were significantly greater than RUS (37%, 77% and 78% respectively). SUS significantly increased the concordance of parathyroid localisation with MIBI (58% versus 32% with RUS).

CONCLUSIONS

SUS improves parathyroid localisation in a British endocrine surgical practice. It is a useful adjunct to parathyroid practice, particularly in centres without a dedicated parathyroid radiologist, and enables more patients with pHPT to benefit from minimally invasive surgery.     

Perineal colostomy: an alternative to avoid permanent abdominal colostomy: operative technique,results and reflection

Background

The most common injury to indicate definitive stoma is rectal cancer. Despite advances in surgical treatment, the abdominoperineal resection is still the most effective operation in radical treatment of malignancies of the distal rectum invading the sphincter and anal canal. Even with all the effort that surgeons have to preserve anal sphincters, abdominoperineal amputation is still indicated, and a definitive abdominal colostomy is necessary. This surgery requires patients to live with a definitive abdominal colostomy, which is a condition that modify body image, is not without morbidity and has great impact on the quality of life.

Aim

To evaluate the technique of abdominoperineal amputation with perineal colostomy with irrigation as an alternative to permanent abdominal colostomy.

Method

Retrospective analysis of medical records of 55 patients underwent abdominoperineal resection of the rectum with perineal colostomy in the period 1989-2010.

Results

The mean age was 58 years, 40 % men and 60 % women. In 94.5% of patients the indication for surgery was for cancer of the rectum. In some patients were made three valves, other two valves and in the remaining no valve at all. Complications were: mucosal prolapse, necrosis of the lowered segment and stenosis.

Conclusion

The abdominoperineal amputation with perineal colostomy is a good therapeutic option in the armamentarium of the surgical treatment of rectal cancer.     

Developing a Robotic Prostatectomy Service and a Robotic Fellowship Programme – Defining the Learning Curve

Introduction

Robotic radical prostatectomy (RRP) is an established treatment for prostate cancer in selected centres with appropriate expertise. We studied our single-centre experience of developing a RRP service and subsequent training of 2 additional surgeons by the initial surgeon and the introduction of United Kingdom''s first nationally accredited robotic fellowship training programme. We assessed the learning curve of the 3 surgeons with regard to peri-operative outcomes and oncological results.

Patients and Methods

Three hundred consecutive patients underwent RRP between November 2008 and August 2012. Patients were divided into 3 equal groups (Group 1, case 1-100; Group 2, case 101-200; and Group 3, case 201-300). Age, ASA score, preoperative co-morbidities and indications for laparoscopic radical prostatectomy were comparable for all 3 patient groups. Peri-operative and oncological outcomes were compared across all 3 groups to assess the impact of the learning curve for laparoscopic radical prostatectomy. All surgical complications were classified using the Clavien-Dindo system.

Results

The mean age was 60.7 years (range 41-74). There was a significant reduction in the mean console time (p < 0.001), operating time (p < 0.001), mean length of hospital stay (p < 0.001) and duration of catheter (p < 0.001) between the 3 groups as the series progressed. The two most important factors predictive of positive surgical margins (PSM) at RRP were the initial prostate specific antigen (PSA) and tumor stage at diagnosis. The overall PSM rate was 26.7%. For T2/T3 tumors the incidence of PSM reduced as the series progressed (Group 1-22%, Group 2-32% and Group 3-26%). The incidence of major complications i.e. grade Clavien-Dindo system score ≤ III was 2% (6/300).

Conclusion

RRP is a safe procedure with low morbidity. As surgeons progress through the learning curve peri-operative parameters and oncological outcomes improve. This learning curve is not affected by the introduction of a fellowship-training programme. Using a carefully structured mentored approach, RRP can be safely introduced as a new procedure without compromising patient outcomes.Key Words: Robotic radical prostatectomy, Prostate cancer, Learning curve, Fellowship training     

Implementation of a novel emergency surgical unit significantly improves the management of gallstone pancreatitis

Introduction

Emergency surgery is changing rapidly with a greater workload, early subspecialisation and centralisation of emergency care. We describe the impact of a novel emergency surgical unit (ESU) on the definitive management of patients with gallstone pancreatitis (GSP).

Methods

A comparative audit was undertaken for all admissions with GSP before and after the introduction of the ESU over a six-month period. The impact on compliance with British Society of Gastroenterology (BSG) guidelines was assessed.

Results

Thirty-five patients were treated for GSP between December 2013 and May 2014, after the introduction of the ESU. This was twice the nationally reported average for a UK trust over a six-month period. All patients received definitive management for their GSP and 100% of all suitable patients received treatment during the index admission or within two weeks of discharge. This was a significantly greater proportion than that prior to the introduction of the ESU (57%, p=0.0001) as well as the recently reported national average (34%). The mean length of total inpatient stay was reduced significantly after the ESU was introduced from 13.7 ± 4.7 days to 7.8 ± 2.1 days (p=0.03). The mean length of postoperative stay also fell significantly from 6.7 ± 2.6 days to 1.8 ± 0.8 days (p=0.001).

Conclusions

A dedicated ESU following national recommendations for emergency surgery care by way of using dedicated emergency surgeons and a streamlined protocol for common presentations has been shown by audit of current practice to significantly improve the management of patients presenting to a busy district general hospital with GSP.     

Auditing orthopaedic audit

INTRODUCTION

Clinical audit plays an important role in the drive to improve the quality of patient care and thus forms a cornerstone of clinical governance. Assurance that the quality of patient care has improved requires completion of the audit cycle. A considerable sum of money and time has been spent establishing audit activity in the UK. Failure to close the loop undermines the effectiveness of the audit process and wastes resources.

PATIENTS AND METHODS

We analysed the effectiveness of audit in trauma and orthopaedics at a local hospital by comparing audit projects completed over a 6-year period to criteria set out in the NHS National Audit and Governance report.

RESULTS

Of the 25 audits performed since 1999, half were presented to the relevant parties and only 20% completed the audit cycle. Only two of these were audits against national standards and 28% were not based on any standards at all. Only a third of the audits led by junior doctors resulted in implementation of their action plan compared to 75% implementation for consultant-led and 67% for nurse-led audits.

CONCLUSIONS

A remarkably large proportion of audits included in this analysis failed to meet accepted criteria for effective audit. Audits completed by junior doctors were found to be the least likely to complete the cycle. This may relate to the lack of continuity in modern medical training and little incentive to complete the cycle. Supervision by permanent medical staff, principally consultants, and involvement of the audit department may play the biggest role in improving implementation of change.     

A further survey of surgical management of the axilla in UK breast cancer patients

INTRODUCTION

The aims of this study were to investigate the practice of axillary lymph node management within different units throughout the UK, and to assess changes in practice since our previous survey in 2004.

SUBJECTS AND METHODS

A structured questionnaire was sent to 350 members of the British Association of Surgical Oncology.

RESULTS

There were 177 replies from respondents who managed more than 100 patients a year with breast cancer. Of these: 12 did not perform axillary ultrasound at all in their centre; 17 (10%) employed axillary node clearance (ANC) on all patients; 122(69%) performed sentinel node biopsy (SNB) with dual localisation; and 111 respondents had attended the New Start Course. Radioisotope was most frequently injected 2 h or more before operation. Just 13 surgeons were convinced of the value of dissecting internal mammary nodes visualised on a scan. Reasons for not using dual localisation included lack of nuclear medicine facilities, no local ARSAC licence holder, no probe, and no funding. Sixty-six surgeons stated that, if they had an ARSAC licence and could inject the radioactivity in theatre, this would be a major improvement. In addition, 83 (47%) did not perform SLNB in patients receiving neo-adjuvant chemotherapy.

CONCLUSIONS

Despite significant changes since 2004, substantial variation remains in management of the axilla. A number of surgeons are practicing outwith current guidelines.     

A multicentre audit of single-use surgical instruments (SUSI) for tonsillectomy and adenoidectomy

INTRODUCTION

Prions are resistant to conventional sterilisation procedures and, therefore, could be transmitted iatrogenically through re-usable adenoid and tonsil surgical instruments. Using disposable instruments would avoid the risk of transmission. We present the results of a complete audit loop using BBraun single-use surgical instruments (SUSI).

PATIENTS AND METHODS

This was a prospective multicentre audit. Surgeons were asked to fill in a standardised questionnaire recording details including postoperative complications, and evaluation of each piece of equipment compared with their own experience of conventional re-usable instruments. In the first cycle, constructive criticisms of the instruments were noted and the manufacturers modified the instruments accordingly. A second cycle of audit was subsequently undertaken.

RESULTS

A total of 86 patients were audited in the first cycle and 97 in the second cycle. Postoperative haemorrhage rate for both cycles was well within acceptable range. In the first audit cycle, surgeons generally found the Draffin rods, Boyle-Davis gag and bipolar diathermy forceps of poor quality and difficult to use. These were redesigned and, on repeat evaluation during the second audit cycle, were found to be just as good, if not better, than the re-usable instruments.

CONCLUSIONS

This study suggests that SUSI may be just as good as re-usable instruments. Furthermore, they may be more cost effective.     

The Role of Laparoscopy in the Management of Groin Hernia

Introduction:

The advantage of using minimally invasive techniques over open techniques in the repair of groin hernias is still debated. Despite its more widespread use, an apparent dichotomy exists. While some surgeons continue to believe that no advantage is gained using the laparoscopic technique, others argue laparoscopic hernia repair (LHR) offers a quicker recovery with the use of a tensionfree repair.

Methods:

A mailing to the general surgeon members of the Society of Laparoendoscopic Surgeons, an international multidisciplinary laparoendoscopic society, was performed (mailing size=l680).

Results:

Nine hundred and ninety-three surgeons responded (60%). Across all demographic variables, 60% of respondents performed approximately 27% of their hernia repairs laparoscopically (40% of respondents did not perform LHR). Surgeon age less than 45 was the only demographic characteristic that predicted the likelihood to perform LHR (p<0.0001) and the percentage of hernias repaired laparoscopically (p<0.005). Most respondents felt that the presence of bilateral hernias (73%) or a recurrent hernia (74%) were indications for LHR. Eighty-nine percent of respondents felt that LHR would still be performed 20 years from now. Surgeons expressed concerns regarding increased cost, the need for more anesthesia, and a lack of long-term follow-up for LHR.

Conclusions:

Only surgeon age predicted the likelihood of a surgeon performing LHR or the percentage of hernias that would be repaired laparoscopically.     

Surgical management of ulcerative colitis: a comparison of Canadian and American colorectal surgeons

Background

Ileal pouch anal anastomosis (IPAA) to surgically manage ulcerative colitis may involve multiple separate surgical procedures, impacting treatment costs, length of stay in hospital, complication rates and patient outcomes, and there is currently no accepted standard of care regarding the number of stages that should be performed. The purpose of this study was to compare the practice patterns of Canadian and American colorectal surgeons regarding the surgical management of ulcerative colitis.

Methods

A questionnaire was mailed to all practisng fellows of the American Society of Colon and Rectal Surgeons (ASCRS) in Canada and the United States. Surgeons were asked to describe their typical practices for 3 clinical scenarios.

Results

Questionnaires were mailed to 40 Canadian and 873 American ASCRS fellows with response rates of 86% and 62%, respectively. In the case of a patient who has had a prior colectomy, who is not taking steroids and in whom a tension-free IPAA is possible, 44% of Canadian surgeons would perform IPAA alone and 56% would perform IPAA with a loop ileostomy. In contrast, only 26% of American surgeons would perform IPAA alone and 74% would perform IPAA with a loop ileostomy (p = 0.002). In the case of a patient who has not had previous surgery, who is taking 10 mg/day of prednisone and in whom a tension-free IPAA is possible, the majority of both Canadian and American surgeons would perform an IPAA with a loop ileostomy (93% and 89%, respectively, p = 0.06). In the case of a patient who has not had previous surgery, who is taking 40 mg/day of prednisone and in whom a tension-free IPAA is possible, 45% of Canadian surgeons would perform a subtotal colectomy with an end ileostomy compared with 14% of American surgeons (p < 0.001).

Conclusion

There are significant differences in the surgical management of ulcerative colitis between Canadian and American colorectal surgeons.     

Evolution in the management of Hirschsprung��s disease in the UK and Ireland: a national survey of practice revisited

INTRODUCTION

The management of Hirschsprung’s disease continues to evolve. This questionnaire survey aimed to determine current surgical management strategies for Hirschsprung’s disease in Britain.

SUBJECTS AND METHODS

The survey was sent electronically to all British paediatric surgeons. Initial questions explored individual experience and regional service provision. Additional questions, reserved for surgeons who perform definitive Hirschsprung’s disease surgery, addressed specific clinical scenarios.

RESULTS

Surveys were sent to 142 surgeons yielding 85 responses. After exclusions, 64 surveys from 21 centres were analysed. Forty-seven respondents worked in centres with designated ‘Hirschsprung’s disease surgeons’. Forty respondents perform definitive Hirschsprung’s disease surgery. In a well neonate with left-sided Hirschsprung’s disease, 34 of 40 surgeons favour primary pull-through following bowel decompression with rectal washouts; 35 of 40 surgeons aim to perform definitive surgery at less than 3 months of age, with 17 favouring laparoscopic-assisted Soave–Boley and 15 favouring an open Duhamel pull-through. Of the 40 surgeons, 36 use a staged approach to right-sided/total colonic Hirschsprung’s disease with 23 favouring a Duhamel or Long Duhamel pull-through.

CONCLUSIONS

The primary pull-through, using an open Duhamel or laparoscopic-assisted Soave–Boley technique, during the first 3 months of life, has become the operative strategy of choice in rectosigmoid Hirschsprung’s disease in Britain. Marked variation in practice remains for right-sided Hirschsprung’s disease.     

UK national survey of management of breast lobular carcinoma in situ

Introduction

There is no national standard treatment for patients with breast lobular carcinoma in situ (LCIS). Association of Breast Surgery guidelines for the management of breast cancer suggest that lesions containing LCIS should be excised for definitive diagnosis and recommend close surveillance after excision biopsy. The aim of this study was to form a picture of the current management of LCIS by UK breast surgeons.

Methods

A questionnaire about the management of LCIS was sent to 490 UK breast surgeons.

Results

Of 490 questionnaires sent out, 173 (35%) were returned. When LCIS is present in a core biopsy, 61% of breast surgeons perform surgical excision, 22% would not excise but would continue follow-up and the remainder perform neither or set no clear management plan. Over half (54%) follow patients up with five years of annual mammography. If classic LCIS were found at the margins of wide local excision, 92% would not re-excise. Conversely, if pleomorphic LCIS were found, 71% would achieve clear margins. Respondents were split evenly regarding management of classic LCIS with a family history as 54% would not alter management whereas 43% would treat the disease more aggressively.

Conclusions

Our survey has shown that in cases where LCIS is found at core biopsy, most surgeons follow Association of Breast Surgery guidance, obtaining further histological samples to exclude pleomorphic LCIS, ductal carcinoma in situ or invasive cancer, whereas others opt for annual surveillance and some discharge the patient. This study highlighted the huge variability in LCIS management, and the need for randomised controlled trials and input into national audits such as the Sloane Project to establish evidence-based national standard guidelines.     

Outcomes of Laparoscopic Partial Nephrectomy after Fellowship Training

Background and Objectives:

Experienced surgeons at select high-volume centers have reported favorable outcomes of laparoscopic partial nephrectomy (LPN) in their contemporary experience. However, it is unclear whether recently fellowship-trained surgeons can replicate such outcomes. We evaluated LPNs performed by 3 surgeons in their initial years of independent practice following laparoscopic fellowship training.

Methods:

Prospectively maintained databases were queried for LPNs performed during the first 3.5 years of practice. Intraoperative parameters, oncological efficacy, and postoperative complications were analyzed.

Results:

Of 138 total LPNs (76 left, 62 right), the mean patient age was 57 years, mean tumor size was 2.52cm, and mean depth of invasion was 1.68cm. Mean OR time was 252 minutes, mean warm ischemia time (WIT) was 26 minutes, and mean estimated blood loss (EBL) was 202 mL. Complications occurred in 7 patients (5%), and conversions occurred in 9 patients (7%). Comparison of the first 15 vs. the last 15 cases demonstrated a significant reduction in mean OR time (204 min vs. 253 min, P=0.007), and mean WIT (24 min vs. 32 min, P<0.001). No significant change was demonstrated for tumor size (2.6 cm vs. 2.4 cm, P=0.390) or EBL (226 mL vs. 220 mL, P=0.922).

Conclusion:

Newly fellowship-trained surgeons performing LPN achieve initial outcomes comparable to those reported by highly experienced surgeons. Further experience reduced total operative and warm ischemia times.     

Perineostomy: the last oportunity

Objective

To review the technique and outcome of perineal urethrostomy or urethral perineostomy and to identify factors related to the procedure failure.

Material and methods

We studied 17 patients who underwent perineal urethrostomy between 2009-2013 in a single hospital. Success was defined as no need for additional surgical treatment or urethral dilatation. We reviewed the clinical data related to age, weight, previous urethral surgery, diabetes, hypertension, ischemic cardiopathy, lichen sclerosus and other causes and studied their association with the procedure failure (univariate analysis). We completed the analysis with a multivariate test based on binary regression.

Results

The average follow-up was 39.41 months. From all the causes, we found Lichen Sclerosus in 35%, idiopathic etiology in 29% and prior hypospadia repair in 18%. Postoperative failure occurred in 3 patients, with a final success of 82.4%. The binary regression model showed as independent risk factors ischemic cardiopathy (OR: 2.34), and the presence of Lichen Sclerosis (OR: 3.21).

Conclusions

The success rate with the perineal urethrostomy technique shows it to be a valid option above all when we preserve the urethral blood supply and plate. Lichen sclerosus and ischemic vascular problems are risk factors to re-stenosis.     

Uptake of an innovation in surgery: observations from the cluster-randomized Quality Initiative in Rectal Cancer trial

Background

Theory suggests the uptake of a medical innovation is influenced by how potential adopters perceive innovation characteristics and by characteristics of potential adopters. Innovation adoption is slow among the first 20% of individuals in a target group and then accelerates. The Quality Initiative in Rectal Cancer (QIRC) trial assessed if rectal cancer surgery outcomes could be improved through surgeon participation in the QIRC strategy. We tested if traditional uptake of innovation concepts applied to surgeons in the experimental arm of the trial.

Methods

The QIRC strategy included workshops, access to opinion leaders, intra-operative demonstrations, postoperative questionnaires, and audit and feedback. For intraoperative demonstrations, a participating surgeon invited an outside surgeon to demonstrate optimal rectal surgery techniques. We used surgeon timing in a demonstration to differentiate early and late adopters of the QIRC strategy. Surgeons completed surveys on perceptions of the strategy and personal characteristics.

Results

Nineteen of 56 surgeons (34%) requested an operative demonstration on their first case of rectal surgery. Early and late adopters had similar perceptions of the QIRC strategy and similar characteristics. Late adopters were less likely than early adopters to perceive an advantage for the surgical techniques promoted by the trial (p = 0.023).

Conclusion

Most traditional diffusion of innovation concepts did not apply to surgeons in the QIRC trial, with the exception of the importance of perceptions of comparative advantage.     

A survey of volunteer reconstructive surgery performed outside of Canada by Canadian plastic surgeons

BACKGROUND:

Members of the Canadian Society of Plastic Surgeons have been offering humanitarian services to countries outside of Canada since the 1960s.

OBJECTIVE:

To document the extent of voluntary reconstructive services performed by members of the Canadian Society of Plastic Surgeons.

METHOD:

A survey was sent to all members of the Canadian Society of Plastic Surgeons asking them to list the extent of their voluntary services.

RESULTS:

Over 80 Canadian Society of Plastic Surgeons members have performed voluntary reconstructive services with more than 40 organizations in over 60 countries.

CONCLUSION:

These voluntary services provide a significant benefit to patients around the world and are rewarding for the surgeons who perform them.     

Breast reconstruction and radiation therapy: A Canadian perspective

BACKGROUND:

When and how best to perform breast reconstruction in the setting of radiation therapy is a much debated topic.

OBJECTIVE:

To investigate the approaches that Canadian plastic surgeons are taking to breast reconstruction in patients who require or may require radiation therapy.

METHODS:

In April 2009, a survey invitation was sent to Canadian plastic surgeons via e-mail. Survey responses were collected over a two-month period.

RESULTS:

Of the 307 invitees, 90 surgeons responded, of whom 76 met the inclusion criteria. Most surgeons (66%) do not perform immediate reconstruction in patients who require postmastectomy radiation. Most respondents (64%) perform immediate reconstructions for patients whose need for radiation is uncertain at the time of mastectomy. Expander and implants is their preferred option, followed by free transverse rectus abdominis myocutaneous (TRAM) flap. Thirty-five per cent use the delayed immediate technique in these cases. Twenty-one per cent are unfamiliar with the delayed-immediate technique. For delayed reconstruction of the irradiated patient, the pedicled TRAM is the most common choice.

CONCLUSIONS:

The reconstructive options are increasing for patients who may need postmastectomy radiation. The use of the delayed immediate technique could increase as physicians gain more knowledge of the technique.     

Reconstruction of perineal defects

Introduction

Perineal defects are commonly encountered in an oncological setting although they may also present as a result of trauma and infection (eg following Fournier’s gangrene). Reconstruction of these poses functional as well as aesthetic challenges. Skin coverage and tissue volume may both be required in addition to anogenital preservation or reconstruction. General prerequisites of an adequate reconstruction of perineal defects include provision of skin cover, well vascularised tissue to fill the dead space (reducing fluid collection and infection), vulvovaginal reconstruction and no faecal or urinary contamination.

Methods

A literature search was performed using PubMed and MEDLINE^®. The search terms included ‘perineal defects’, ‘perineal reconstruction’, ‘perforator flaps for perineum’, ‘vulval flaps’, ‘secondary healing of wound’ and ‘vacuum assisted closure’. Backward chaining of reference lists from retrieved papers was also used to expand the search.

Findings

Modern developments have led to an increased expectation in improved quality of life as the main goal of reconstruction, therefore necessitating surgery with less morbidity and early return to normal activity. Progress in microsurgical procedures has been the main recent advance in perineal reconstruction and, in future, refinements in perforator flap design and tissue engineering techniques will lead to even better reconstructions.     

Effects of change in rectal cancer management on outcomes in British Columbia

Background

In a province-wide audit of patients undergoing treatment for rectal cancer in British Columbia in 1996, the 4-year rate of pelvic recurrence for stage 3 rectal cancer was 27%. The management guidelines were changed in 2002 to include adjuvant short-course preoperative radiation and total mesorectal excision surgical techniques. Education workshops were held to implement the protocol change.

Methods

We performed a provincial audit of rectal cancer cases for patients treated in the year after the protocol change, and we compared the pelvic recurrence rates with those from the audit performed in 1996.

Results

During a 12-month period beginning Oct. 1, 2003, a total of 367 patients underwent radical resection of rectal cancer with a curative intent. Preoperative adjuvant radiotherapy was used in 54% of cases (197/367). Median follow-up was 34.5 months, and 91% of patients were followed for at least 2 years. Relative to the 1996 cohort, there was a decreasing trend in 2-year overall pelvic recurrence rates in the 2003/04 cohort (9.6% v. 6.9%) and a significant decrease in recurrence among patients with stage 3 cancers (18.2% v. 9.2%; p = 0.020). Use of adjuvant radiation increased significantly (37% v. 65%; p < 0.001), and negative radial margins were achieved in 87% (319/367) of cases.

Conclusion

The rates of pelvic recurrence were improved after changes in the management guidelines advocating increased use of total mesorectal excision surgery and preoperative radiation. Knowledge translation with an integrated strategy among surgeons and medical and radiation oncologists was successful in improving population outcomes among patients with rectal cancer.     

Substantial variation of both opinions and practice regarding perioperative fluid resuscitation

Background

There are no current standards of care guiding perioperative fluid administration, and clinicians continue to debate restrictive versus liberal fluid administration. We sought to simultaneously evaluate the opinions and practice of surgeons, intensivists and anesthesiologists in a single centre regarding perioperative fluid resuscitation.

Methods

A postal survey sent to surgeons, intensivists and anesthesiologists in a single academic health care centre presented case-based scenarios followed by questions on fluid requirements and 5-point Likert scales involving statements about resuscitation. We performed a retrospective chart review to evaluate amount and type of intra-and postoperative (72-h) fluid administration, urine output and postoperative ventilation time in patients undergoing uncomplicated esophagectomy or pneumonectomy.

Results

Seventy-four of 77 respondents (96%) agreed that precise fluid resuscitation diminishes the risk of adverse events. Surgeons overall gave less fluids than anesthesiologists or intensivists and used fewer resuscitation end points to estimate fluid requirements perioperatively. For right hemicolectomies, only 3% of surgeons chose a fluid rate greater than 150 mL/h, compared with 55% of intensivists. We reviewed 49 patients’ charts (25 who had pneumonectomies, 24 who had esophagectomies) retrospectively. The coefficient of variation (COV = standard deviation divided by its mean) of fluid administration intraoperatively was 0.56 for pneumonectomy and 0.35 for esophagectomy; postoperatively, the COV was greater than 0.50 for the first 24 hours, but less than 0.50 after 24 hours postoperatively.

Conclusion

The presence of substantial variability of both opinion and practice of perioperative fluid resuscitation in a single centre supports the need for further research to identify objective methods to define perioperative fluid requirements and standards of perioperative resuscitation.
