Systematic Review and Meta-Analysis of Epidural Analgesia Versus Different Analgesic Regimes Following Oesophagogastric Resection.

INTRODUCTION: Effective analgesia following open oesophagogastric (OG) resection is considered a key determinant of recovery. This review aimed to compare epidural to alternative analgesic techniques in patients undergoing major open resection for OG cancer. METHODS: A systematic review and meta-analysis was conducted of randomized controlled trials comparing epidural with alternative analgesic methods in open OG surgery. Primary outcome was the overall post-operative morbidity rate. Secondary outcomes included pulmonary complication rates, length of stay (LOS) and pain scores at 24 h. RESULTS: Six trials which comprised of 249 patients were identified (3 following gastrectomy and 3 following oesophagectomy). Following gastrectomy, secondary outcomes including pulmonary complications and dynamic pain scores at 24 h were improved in the epidural groups. No difference was observed in overall morbidity rates or LOS. Following oesophagectomy, overall morbidity rates were not reported at all. LOS was not shortened, and rest pain was not significantly different in the epidural group, but dynamic pain scores were reported to be improved. CONCLUSION: Few trials of analgesic regimen have been performed following open OG resection. In those trials that have been performed, epidural analgesia has not been shown to reduce overall morbidity. Epidural is associated with reduced pulmonary complications after gastrectomy, but no benefit has been shown after oesophagectomy. Whilst widespread investigation of minimally invasive OG techniques currently takes place, it is clear that the most effective patient pathway following open OG surgery, particularly oesophagectomy, is still not proven. Further trials are required.

Surgical and endoscopic management of high grade dysplasia and early oesophageal adenocarcinoma.

BACKGROUND: The introduction of endoscopic techniques has led to debate about optimal management of early oesophageal adenocarcinoma. The aim was to evaluate patient selection and outcomes for endoscopic or surgical treatment at a tertiary referral centre. METHODS: A prospectively collected database of consecutive patients staged with high-grade dysplasia (HGD) or T1 oesophageal adenocarcinoma treated with curative intent between 2005 and 2013 was undertaken. All patients were discussed at the multidisciplinary team meeting. Surgical treatment was by thoracoscopic assisted or standard/laparoscopic assisted Ivor Lewis oesophagectomy. Endoscopic treatment was a structured programme of endoscopic mucosal resection (EMR) and/or radiofrequency ablation (RFA). Outcomes included treatment variables, recurrence and complications. RESULTS: 83 patients treated; 50 with endoscopic therapy (EMR only-4, EMR then RFA-22, RFA only-24) and 38 by surgery (33 straight to surgery and 5 following EMR). Median age (67) and mean follow-up (21 months) were similar. HGD was more common in the endoscopic group (32/50, 64%, vs.3/33, 9%, p = 0.0001). Significant complications were more common following surgery (13/38, 34%, vs. 1/50, 2%, p = 0.0001). There were two in-hospital deaths following oesophagectomy (1 open, 1 thoracoscopic). Endoscopic treatment beyond 12 months for persisting HGD/intramucosal disease was required in 2 patients. Recurrence of HGD/invasive cancer was diagnosed in 2/36 (5.6%, T1a recurrence) of endoscopic and 1/38 (2.6%, T2N0 - subsequent hepatic metastases) surgical patients. CONCLUSION: A management algorithm including both endoscopic treatment and oesophagectomy provides optimal outcome for these patients. Due to additional morbidity of surgery, endoscopic treatment is appropriate first-line treatment.

Neoadjuvant chemotherapy for carcinoma of the oesophagus and oesophago-gastric junction: a six-year experience.

BACKGROUND: Oesophageal cancer is a major clinical problem with a generally poor prognosis. As a result there has been interest in combining surgery with neoadjuvant chemotherapy to try and improve outcomes, although the current evidence for benefit is inconsistent. We aimed to compare, in a non-randomised study, the post-operative complication rate and short and long-term survival of patients who underwent surgical resection for carcinoma of the oesophagus and types I and II carcinoma of the oesophago-gastric junction with or without neo-adjuvant chemotherapy. METHODS: Details of all resections for oesophageal/junctional (types I and II) adenocarcinoma or squamous cell carcinoma between April 2000 and July 2006 were collected prospectively. Data from patients with T3 and/or N1 disease who underwent either neoadjuvant chemotherapy (NAC) or not (non-NAC) were compared. Data were analysed using Kaplan-Meier plots, Mann-Whitney U-test, Cox Regression modelling, and Chi-squared test with Yates' correction where sample sizes <10. RESULTS: 167 patients were included (89 NAC and 78 non-NAC). The in-hospital post-operative mortality rate of the NAC group (n = 2 deaths; 2.2%) was significantly lower (p = 0.045) than the non-NAC group (n = 6 deaths; 7.7%). Most deaths were due to cardio-respiratory complications; however, there was no significant difference in rates of chest infections, anastomotic leaks, wound infections, re-operations, readmission to ITU or overall complications between the two groups. Although both the two-year survival rate (60.7%) and long-term survival of NAC patients (median survival = 793 days; 95% CI = 390-1196) was greater than non-NAC patients (two-year survival rate = 48.7%; median survival = 554 days; 95% CI = 246-862 respectively), these differences were not statistically significant. CONCLUSION: This non-randomised study demonstrated that NAC was associated with a significant reduction in post-operative inpatient mortality rate. Whether this can be explained by a decreased co-morbidity in NAC patients or a protective phenomenon associated with NAC remains unclear. This study also demonstrated a greater two-year survival rate and overall median survival time following NAC but this was not statistically significant.

Long-term outcomes following laparoscopic anterior and Nissen fundoplication.

BACKGROUND: Limited evidence exists to which operation gives best long-term outcomes for gastro-oesophageal reflux disease. This study aimed to assess long-term symptomatic outcome and satisfaction following laparoscopic anterior (LA) or Nissen fundoplication in a specialist upper gastrointestinal unit. METHODS: Patients who underwent primary LA or Nissen (LN) fundoplication between May 1994 and June 2010 were identified from a prospectively collected database. DeMeester, modified DeMeester, 'Gastrointestinal Symptom Rating Scale' scores and patient satisfaction were assessed by questionnaire. RESULTS: A total of 387 patients underwent surgery and 246 patients (65%) completed questionnaires, with 181 LA patients and 65 LN patients. Median follow-up was 83 months for LA and 179 months for LN (P < 0.001). A total of 218/245 (89%) reported major improvement in symptoms and 27 (11%) reported poor outcomes. There was no differences between LA and LN for symptom scores at short (<5 years) or long-term follow-up (>5 years). Women reported significantly higher DeMeester scores and lower satisfaction (P = 0.012). One hundred and eighteen (48%) patients were taking proton pump inhibitors (PPI) at follow-up despite high satisfaction rates. CONCLUSION: LA and LN have similar long-term results with patients reporting high satisfaction levels. Women reported more symptoms and less satisfaction than men. Despite high satisfaction rates a high percentage of patients take PPIs.
