Abstract
Abstract
Background
Little is known about unwarranted variations in care and outcomes of patients who undergo surgical repair for type A acute aortic dissection(TAAD). We aim to investigate decade-long trends in TAAD surgical repair in England.
Method
Retrospective review of the National Institute for Cardiovascular Outcomes Research (NICOR) National Adult Cardiac Surgery Audit (NACSA) registry from January 2009 to December 2018 , which prospectively collects demographic and peri-operative clinical information for all adult cardiac surgery procedures in the UK.
Results
Over the 10-year period,3,686 TAAD patients underwent surgical repair in England. A steady doubling in the overall number of operations conducted in England was observed from 237 cases recorded in 2009 to 510 in 2018. Number of procedures per hospital per year also doubled, from 10 in 2009 to 21 in 2018. The risk profile of the operated patients remained unchanged. Overall, in-hospital mortality was 17.4% with a trend toward lower mortality in the most recent years (from 22.8% in 2009 to 14.7% in 2018). There was a significant variation in operative mortality across regions with a trend towards lower mortality in regions with a high-volume hospital.
Conclusions
Surgery is the only treatment for acute TAAD but is associated with high mortality. Prompt diagnosis and referral to a specialist center is paramount. The number of operations conducted in England has doubled in 10 years and the associated survival following surgery has improved. Regional variations exist in service provision with a trend towards better survival in high volume centers.

Abstract
AIM As resective surgery for oesophageal carcinoma is only appropriate for a selected cohort of patients, preoperative staging plays an important role in the management of these patients. This study assessed the accuracy of endoscopic ultrasound (EUS) staging in comparison with computerised tomography (CT) staging and the impact of EUS in management of patients with oesophageal carcinoma undergoing gastro-esophagectomy. METHODS Ninety-six consecutive patients with oesophageal carcinoma underwent preoperative staging with multislice CT and EUS. Of these, 50 patients underwent gastro-esophagectomy, allowing preoperative staging data from these imaging modalities to be compared to postoperative histopathological staging, classified according to the TNM system. Management plans for these patients made without use of EUS were then compared to those following EUS staging. RESULTS The overall accuracy rate of EUS for T staging was 64%, showing good agreement with postoperative histopathological staging of the resected specimen (weighted k=0.42, 95%CI= 0.32-0.52). In terms of clinical decision making, the T stage accuracy rose to 90% when differentiating T1 from T2/3 lesions. In terms of N staging, the overall accuracy was 72% (weighted k=0.44, 95% CI=0.34-0.54). In comparison, N staging by CT was significantly less accurate (62% vs 72%, P<0.01, chi squared) and showed poor agreement with postoperative histopathological nodal staging (weighted k=0.24, 95%CI =0.11-0.37). Importantly, in 56% of patients, staging information obtained from EUS instigated change in management compared to that configured without EUS. CONCLUSION EUS enhances preoperative staging of oesophageal cancer and is important in preoperative clinical decision making process, especially with increasing use of neoadjuvant chemotherapy.

Abstract
Synchronous tumours of the thymus and lung are rare. We describe the case of a 57-year-old gentleman, who presented with a large type AB thymoma in the superior anterior mediastinum and a primary bronchogenic adenocarcinoma in the right upper lobe. In view of this, he underwent surgical resection of the thymoma directly through amedian sternotomy and right upper lobectomy via the median sternotomy with video assisted thoracoscopic guidance.

Abstract
Adult cardiac surgery in patients with malrotation of the heart is rare. A 60 year-old lady, with known cardiac dextroversion, presented with dyspnoea and pre-syncopal attacks. Echocardiographical and radiological investigation confirmed the dextroversion, with clockwise rotation of the heart through its longitudinal axis. This resulted in the right ventricular outflow tract and pulmonary artery being wrapped anteriorly around the aorta, with posterior displacement of the right atrium. The presence of a heavily calcified, bicuspid aortic valve and dilated ascending aorta was also demonstrated. At surgery, venous cannulation was established by rotating the heart anticlockwise and access to the aortic valve gained with a more superior oblique aortotomy. In the presence of a dilated ascending aorta with a calcified, bicuspid aortic valve, the aortic root was replaced with a valved conduit. To the authors' knowledge, this is the first report of an aortic root replacement in a patient with cardiac dextroversion.

Abstract
AIM The aim of this study was to analyse the outcomes of patients admitted to the intensive care unit (ICU) following initial recovery after elective thoracic surgery. METHODS The case notes of all patients who underwent elective thoracic surgery over a one-year period were reviewed. Patients who were admitted to ICU following an initial recovery on the ward were identified and their postoperative course analysed. The clinical and demographic characteristics of these patients were recorded and their outcomes analysed. RESULTS A total of 20 patients were admitted to ICU of whom 13 (65%) were admitted for respiratory complication, 5 with sepsis and 2 with cardiovascular instability. Sixteen (80%) patients required CPAP or BIPAP, of whom only 7 (35%) required mechanical ventilation. Renal support was required in 7 patients, with 2 (10%) requiring haemofiltration. ICU survival was 15 patients (75%), whilst overall three-month survival post ICU admission was 65%. Requirement for renal support was the only predictor of mortality on univariate and multivariate analysis. CONCLUSIONS Salvage ICU admission following elective thoracic surgery is associated with significant mortality, however the outcome is far from hopeless. The majority of patients can be managed without recourse to mechanical ventilation or haemofiltration. The need for renal support is, however, a significant adverse prognostic indicator.

Abstract
OBJECTIVE The choice of analgesia in the management of post-thoracotomy pain remains controversial. Although several alternative forms of post-thoracotomy analgesia exist, all have their disadvantages. Cryoanalgesia, localized freezing of intercostal nerves, has been reported to have variable effectiveness and an incidence of long-term cutaneous sensory changes. We carried out an animal study to assess the reversibility of histological changes induced by cryoanalgesia and a prospective randomized trial to compare the effectiveness of cryoanalgesia with conventional analgesia (parenteral opiates). METHODS In six anaesthetized dogs, intercostal nerves were exposed to a varying duration of cryo-application (30, 60, 90 and 120 s). The nerves were biopsied and examined histologically at regular intervals over the following 6 months. In the clinical study, 200 consecutive patients undergoing thoracotomy were randomized to cryoanalgesia and conventional (parenteral opiates) analgesia groups. Postoperative pain scores, respiratory function tests and use of opiate analgesia were measured for the two groups. RESULTS Following application of the cryoprobe, degeneration and fragmentation of the axons was evident with associated inflammatory changes. As the endoneurium remained intact, axonal regeneration took place after the resolution of axonal swelling. Over the course of weeks, recovery of the intercostal nerve occurred and was complete after 1 month for the 30 and 60 s groups. For nerves exposed to longer durations of cryoanalgesia, the time taken for complete recovery was proportionally increased. Clinically, there was a statistically significant (P<0.05) improvement in postoperative pain scores and use of opiate analgesia and an improvement (P>0.05) in respiratory function tests for patients in the cryoanalgesia group. The previously suggested cutaneous sensory changes resolved within 6 months with complete restoration of function. CONCLUSIONS We suggest that cryoanalgesia be considered as a simple, inexpensive, long-term form of post-thoracotomy pain relief, which does not cause any long-term histological damage to intercostal nerves.

Abstract
Septic complications are rare following laparoscopic cholecystectomy if prophylactic antibiotics are given, as demonstrated in previous studies. Antibiotic treatment may be unnecessary and, therefore, undesirable, so we compared two forms of prophylaxis: a cephalosporin antibiotic and bag extraction of the dissected gallbladder. A total of 76 patients undergoing laparoscopic cholecystectomy were randomised to either receive an antibiotic or to have their gallbladder removed from the abdomen in a plastic bag. Complicated cases were excluded. There was a total of 6 wound infections (7.9%), 3 in each of the study groups. All these were associated with skin commensals. There were no other septic complications. Bacteriological studies grouped the organisms isolated from the bile and the wound as potential pathogens and likely commensals. A total of 10 potential pathogens were isolated, 9 of which were found in the group receiving antibiotics. We conclude that septic sequelae of uncomplicated laparoscopic cholecystectomy are uncommon, but clearly not entirely prevented by antibiotic or mechanical prophylaxis. Prophylactic antibiotics may not be required in uncomplicated laparoscopic cholecystectomy. Further study is warranted.

Abstract
BACKGROUND Postoperative mediastinal false aneurysm is associated with a substantial morbidity and mortality. Surgical treatment is mandatory, although the individual approach varies according to the type of pathologic process, infection status, and site of origin of the aneurysm. METHODS Between April 1993 and February 1999, we treated 10 patients, aged 25 to 73 years, with anastomotic mediastinal false aneurysm originating from the proximal thoracic aorta. Nine had undergone prior operations on the ascending aorta (7, type A dissection repair; 1, aortitis; 1, root abscess) with a Dacron conduit (n = 5) or valved conduit (n = 4). The last patient had undergone valve replacement for excavating aortic root sepsis. False aneurysms were detected from 2 to 70 months after the most recent operation. Three patients had positive tissue cultures. The surgical procedure was direct suture repair of the disrupted anastomosis in 5, root or ascending aortic replacement with an aortic homograft in 4, and Dacron graft interposition in 1. Hypothermic low-flow perfusion with or without circulatory arrest was used in all patients. RESULTS There was one hospital death caused by staphylococcal mediastinitis. A false aneurysm recurred after direct suture repair in 2 patients with underlying type A dissection or aortitis. This resulted in one late death. One patient experienced a neurologic event during removal of an infected vascular graft. All 8 surviving patients are alive and well after a mean follow-up of 2 years. Three patients with mycotic false aneurysms remain free from infection after aortic homograft replacement. CONCLUSIONS Mediastinal false aneurysms are surgically taxing. Low-flow hypothermic perfusion with or without circulatory arrest allows safe reentry. Radical surgery provides a satisfactory outcome in infected patients. Local repair of suture dehiscence in pathologic tissues may predispose to recurrence. We suspect that excessive use of formalin in gelatin-resorcin-formol glue may predispose to tissue necrosis.

Abstract
Sural nerve injury is a complication of Achilles Tendon (TA) rupture. We dissected 30 cadaveric lower limbs to describe the course of the sural nerve in relation to the TA. At the level of insertion of the TA into the calcaneum, the sural nerve was a mean 18.8 mm from the lateral border of the TA. The proximal course of the nerve was towards the midline such that it crossed the lateral border of the TA at a mean distance of 9.8 cm from the calcaneum. The significant individual variation in the position of the sural nerve in relation to the achilles tendon should be borne in mind when placing sutures in the proximal part of the achilles tendon. Percutaneous sutures should not be placed in the lateral half of the TA.
