Feasibility of a consultant-led, trainee-delivered urgent laparoscopic cholecystectomy service.

BACKGROUND: Urgent laparoscopic cholecystectomy has become the gold standard for the treatment of acute gallstone disease. Since 2005 we have implemented a consultant-delivered urgent surgical service for this condition. In an attempt to increase the capacity of this service, we have recently introduced a new policy of also allowing selected trainee surgeons to perform urgent laparoscopic cholecystectomy with consultant assistance available on request. The purpose of this study was to audit our initial experience of this new service. METHODS: Patients with acute gallstone disease had their surgery performed by a consultant or a trainee operating independently with consultant assistance available only on request. Allocation was based purely on surgeon availability. The clinical outcomes of 50 consecutive trainee and 50 consecutive consultant cases were compared and an attempt made to identify pre-operative predictors of technically-demanding trainee cases requiring consultant intervention. RESULTS: The mean operating time of trainees was significantly longer than consultants (80 +/- 5 mins vs 55 +/- 4 mins, p <0.001) although the conversion rates for trainees (4%) and consultants (2%) were similar. There were no significant differences between the groups with respect to postoperative morbidity. Of the 50 trainee cases, consultant intervention was required in 12 (24%) cases. There were no statistically significant pre-operative predictors of requirement for consultant assistance. CONCLUSIONS: Urgent laparoscopic cholecystectomy may be performed independently by appropriately skilled trainees within a consultant-led service. Although consultant intervention is often not required, the requirement for consultant assistance cannot be easily predicted based on pre-operative data.

Leg ulceration: the importance of treating the underlying pathophysiology.

The last 20 years have seen considerable advances in the management of vascular diseases both in non-invasive imaging and minimally invasive surgical interventions. Colour duplex ultrasonography provides non-invasive and increasingly high-resolution anatomic and haemodynamic vascular information. This has been complimented by the development of minimally invasive interventional procedures such as subintimal angioplasty and endovenous treatments, all of which can be performed under local anaesthesia. These advances can now be utilized to improve both the assessment and management of patients with chronic leg ulceration where the aetiology is usually vascular and mostly primary venous insufficiency. Using non-invasive Doppler pressures and colour duplex imaging, the anatomic and haemodynamic pattern of the underlying vascular disease (and consequently the pathophysiology) can be precisely determined. This enables appropriate planning and targeting of effective management from an early stage in the history of any particular ulcer. This paper highlights the importance of achieving accurate diagnosis and instituting effective treatments that are appropriately targeted at the underlying pathophysiology, in patients with chronic leg ulceration, and describes how recent advances in technology and interventions have substantially increased the tools available to the vascular specialist. Thus allowing safe and effective management of what can otherwise become a prolonged or recurrent disease process.

Reduced access aortic exposure (RAAE) technique for infrarenal abdominal aortic aneurysm (AAA) repair.

OBJECTIVE: A reduced access aortic exposure (RAAE) technique for repair of infrarenal AAA repair has been evaluated and the short-term surgical outcomes are compared with conventional open repair (OPEN). METHODS: All consecutive patients having repair of infrarenal AAA over a period of 3 years were included in this study. A group of these patients had AAA repair using the RAAE technique with a small midline incision (<8 cm). Patient characteristics and peri-operative outcomes were compared with the other group treated with the traditional full-length midline incision (OPEN). RESULTS: Sixty patients underwent AAA repair in this study (38 in the RAAE group and 22 in the OPEN group). The age, sex distribution and co-morbidities were similar across the two groups (median age 76 and 75 years respectively). The RAAE group had a significantly shorter Intensive care stay (2 vs. 4 days, p=0.041) and a shorter total hospital stay (9 vs. 14 days, p=0.004). Significant postoperative chest infection was recorded in 13% (5/38) in the RAAE group as compared to 41% (9/21) in the OPEN group (p=0.025). CONCLUSIONS: The RAAE technique for infra renal AAA repair is feasible and safe, and allows quicker postoperative recovery with comparable morbidity and mortality to the conventional technique.

Urgent cholecystectomy for acute cholecystitis in a district general hospital - is it feasible?

INTRODUCTION: Laparoscopic cholecystectomy has become the gold standard for treatment of symptomatic gall stone disease. However, its place remains controversial in the management of acute cholecystitis due to a high reported incidence of bile leaks and conversion rate. Tertiary referral centres have reported good results. We present a series of cases after the introduction of an urgent cholecystectomy pathway in a district general hospital. PATIENTS AND METHODS: A practice of urgent cholecystectomy for acute cholecystitis was introduced by three consultant general surgeons. All prospective patients having an urgent laparoscopic cholecystectomy for acute cholecystitis, over an 8-month period were entered into a database. A dedicated ultrasound service was instituted to provide prompt diagnosis in these patients. Their demographic details, operative findings, laboratory results were recorded in a prospective database. Timing of ERCP, postoperative complications and conversion rate and hospital stay were also noted. RESULTS: There were 64 patients in the study with a median age of 51 years (range, 21-84 years). There were 21 males and 43 females. All patients underwent laparoscopic cholecystectomy during the index admission. Eleven patients had pre-operative ERCP and 12 patients had on-table cholangiogram. There were no conversions. Postoperative ERCP was required in six patients. The median time interval between admission and operation was 3 days (range, 2-7 days). There were two bile leaks but no common bile duct injury. There were two cases of superficial wound infection. One patient required re-operation for small bowel obstruction secondary to a port site hernia. CONCLUSIONS: Urgent laparoscopic cholecystectomy for acute cholecystitis is a feasible treatment option in a district general hospital. A safe practice can be ensured by adherence to a care pathway and a multidisciplinary, consultant-delivered service. Urgent cholecystectomy service can be provided safely in a district general hospital with outcomes comparable to previously published literature.

Blood and body fluid splashes during surgery--the need for eye protection and masks.

INTRODUCTION: While most surgeons make an effort to avoid needlestick injury, some can pay little attention to reduce the potential route of infection occurring when body fluids splash into the eye. It has been shown that transmission of HIV, hepatitis B or C can occur across any mucous membrane. This study aims to quantify how frequently body fluids splash the mask and lens of wrap around protective glasses thus potentially exposing the surgeon to infection. PATIENTS AND METHODS: A prospective study was carried out by a single surgeon on all cases performed over a 1-year period. Protective mask and glasses were examined before and after operations. RESULTS: A total of 384 operations were performed with 174 (45%) showing blood or body fluid splash on the lens. A high incidence of splashes was found in vascular surgical procedures (79%). All amputations showed splash on the protective lens. Interestingly, 50% of laparoscopic cases resulted in blood or body fluid splash on the protective lens. CONCLUSIONS: This study has shown a high incidence (45%) of blood and body fluid splashes found on protective glasses and masks. There was a very high incidence (79%) during vascular surgical procedures. With the prevalence of HIV and hepatitis increasing, it seems prudent to protect oneself against possible routes of transmission.

Diaphragm disease: the limitation of laparoscopy and assessment of the small bowel for strictures using a ball bearing.

Diaphragm disease is a rare cause of intestinal obstruction that will be seen with increasing frequency with the widespread use of nonsteroidal anti-inflammatory drugs (NSAIDs). We present a case study of a patient with diaphragm disease where the diagnosis was not apparent at laparoscopy, and passage of a steel ball through the small intestine was required to identify all strictures present. A high index of suspicion, recognition of the limitations of conventional diagnostic aids, and the need to assess the full length of the small bowel are all important in the surgical management of this condition.

Surgical correction of isolated superficial venous reflux reduces long-term recurrence rate in chronic venous leg ulcers.

OBJECTIVES: surgical correction of isolated superficial venous reflux in ulcerated legs may reduce short term recurrence rates but the longer term benefits are unknown. DESIGN: prospective non-randomised cohort study. METHODS: consecutive patients with chronic leg ulcers were prospectively assessed at a one-stop clinic over a 4-year period from July 1995 to July 1999. All patients with ankle brachial pressure indices (ABPI)50.85 were initially treated with weekly four-layer bandaging. Venous duplex studies in all ulcerated legs assessed venous reflux pattern with surgery being offered to all those with isolated superficial reflux, of whom 56% accepted. Patients were advised to wear class two elastic compression stockings after healing. RESULTS: 766 legs in 669 patients were assessed. Six hundred and thirty-three legs had an ABPI50.85, 236 (39%) demonstrating isolated superficial venous reflux. Surgery was performed on 131 of these legs. Twelve and 24 week healing rates were 50% and 72% for operated legs and 62% and 74% for non-operated legs (p=0.67; Kaplan-Meier life table analysis). Recurrence rates at 1, 2 and 3 years were 14%, 20% and 26% for operated legs and 28%, 30% and 44% for non-operated legs (p=0.03; Kaplan-Meier life table analysis). CONCLUSION: surgical correction of superficial venous reflux in legs with chronic leg ulceration may reduce ulcer recurrence rate at 1, 2 and 3 years.

Influence of a specialized leg ulcer service on management and outcome.

BACKGROUND: The organization of leg ulcer care is poorly defined in the community. This study assessed the overall influence of a specialized community service on management and outcome of chronic leg ulcers, irrespective of aetiology. METHODS: Assessment and outcome of ulcers were compared in patient samples (n = 200) from East and West Gloucestershire, before and after the introduction of specialized clinics into East Gloucestershire. In clinics, vascular disease was routinely assessed by duplex scanning and determination of the ankle : brachial pressure index. RESULTS: There was no coordinated community structure for the care of patients with leg ulcers before the service was introduced, and 74 and 67 per cent of limbs in East and West Gloucestershire respectively had aetiology undiagnosed. After introduction of the clinics, the 12-week healing rate increased from 12 to 22 per cent in East Gloucestershire (P = 0. 05) and to 47 per cent in the specialized East Gloucestershire clinics (P < 0.001). The 12-month recurrence rate decreased from 50 to 41 per cent in East Gloucestershire and to 17 per cent in the East clinics (P < 0.001). The West Gloucestershire control showed no significant changes. CONCLUSION: A specialized leg ulcer service with defined protocols provides an improved management structure for treating patients with leg ulcers in the community. Accurate diagnosis of chronic leg ulcers and improved outcome may be achieved within this specialized service.

The diagnosis and management of mixed arterial/venous leg ulcers in community-based clinics.

OBJECTIVES: To assess a management protocol for mixed arterial/venous leg ulcers in a community service. DESIGN: Two-year prospective study of outcome with intention of assessing limbs with mixed arterial/venous ulcers when managed by a new protocol. METHOD: Limbs were assessed for venous reflux by duplex and arterial insufficiency by ankle-brachial pressure index (ABPI) and defined into three categories: ABPI > 0.85, 0.5 > ABPI < or = 0.85 (moderate), ABPI < or = 0.5 (severe). Four-layer compression was applied to limbs with normal arteries. Modified compression was applied to limbs with venous and moderate arterial disease with treatment failure triggering arterial imaging and revascularisation. Limbs with venous and severe arterial disease were investigated for revascularisation. RESULTS: Of 267 consecutive limbs, 221 had pure chronic venous ulcers and 46 had mixed arterial/venous ulcers with 33 having moderate and 13 having severe arterial disease. Thirty-six week healing rates for chronic venous, moderate arterial/venous and severe arterial/venous ulcers were 70%, 64% and 23%, respectively. CONCLUSION: Limbs with mixed moderate arterial/venous ulcers achieved rates comparable with venous ulcers with this protocol although nurse-led surveillance was required. Limbs with mixed severe arterial/venous ulcers healed slowly despite an aggressive approach to correct arterial disease.

Influence of a specialised leg ulcer service and venous surgery on the outcome of venous leg ulcers.

OBJECTIVES: To assess the influence of a vascular-led community service on the outcome of chronic leg ulcers. DESIGN: Before and after study. METHOD: Healing and recurrence were compared between ulcerated limbs (n = 149) from a random sample of 200 patients treated in the community and consecutive limbs (n = 200) from 180 patients treated in specialised clinics. In these clinics, vascular disease was routinely identified with venous duplex and ankle-brachial pressure index. Surgery was offered if superficial vein reflux alone was detected. Compression bandaging was applied to limbs with ABPI > 0.85. Healed limbs were treated with compression hosiery. RESULTS: After the clinics were introduced, the 12 and 24-week healing rates increased from 12 and 29 per cent to 53 and 68 per cent respectively (p < 0.01), and the 6 and 12 month recurrence rates decreased from 43 and 54 per cent to 21 and 23 per cent respectively (p < 0.01). Superficial venous surgery reduced recurrence at 1 year to 9 per cent. CONCLUSION: Outcome of leg ulcers is improved in a vascular-led community service. Routine surgical correction, in cases of reflux limited to the superficial system, may further reduce the chance of recurrence.

Quality of life after transthoracic endoscopic sympathectomy for upper limb hyperhidrosis.

OBJECTIVE: To assess the outcome after transthoracic endoscopic sympathectomy (TES) for upper limb hyperhidrosis. DESIGN: Prospective cohort study. SETTING: District general hospital. SUBJECTS: Consecutive patients undergoing TES for upper limb hyperhidrosis over a fifteen month period. INTERVENTIONS: One-stage bilateral TES. MAIN OUTCOME MEASURES: Change in quality of life as shown by the Short Form-36 health assessment questionnaire. RESULTS: Sixteen patients (11 women and 5 men, median age 26 years) underwent operation without complications. At median follow-up of 6.2 months, symptomatic improvement was found in 26 of 32 limbs treated (82%). Truncal compensatory hyperhidrosis was reported by 13 patients but was severe in only three. There were significant improvements in social function (p = 0.01) and mental health (p = 0.025) as assessed by the SF-36. CONCLUSION: Despite a high incidence of compensatory hyperhidrosis, TES improved both the symptoms and overall quality of life in patients with upper limb hyperhidrosis.

Colour duplex ultrasonography in the rational management of chronic venous leg ulcers.

Colour duplex ultrasonographic imaging has largely replaced venography in the assessment of lower-limb venous disorders. This is a study of the use of duplex in the management of patients with chronic venous ulceration in community ulcer clinics. Patients with chronic leg ulceration and an ankle: brachial pressure index of 0.85 or greater were studied. Assessment of venous competence in both the deep and superficial systems of the affected and unaffected legs was performed using colour venous duplex imaging. Reflux was defined as reverse flow for greater than 1 s after manual calf compression. One hundred consecutive patients were assessed over 15 months. Of 111 ulcerated legs, 96 had active ulceration, while 15 had been ulcerated within the previous 6 months. Fifty-seven (51 per cent) of the 111 ulcerated legs had superficial incompetence alone (88 per cent long saphenous system or its perforators, 12 per cent short saphenous system). Six legs (5 per cent) had isolated deep venous incompetence. Forty-two legs had mixed superficial and deep venous reflux; 22 of these had undergone previous venous surgery. Colour venous duplex assessment demonstrated superficial venous disease in approximately half of limbs with chronic leg ulceration. Venous dysfunction in these patients is potentially curable by surgery.
