Negative margins and bone resection (where needed) were identified as the most important factors influencing overall survival. Neoadjuvant therapy before pelvic exenteration did not affect survival, but was associated with higher rates of readmission, complications and radiological reintervention.

However, it is not without significant risk. This study aimed to audit the effect of EA and ultrasonography placed rectus sheath catheters (RSCs) on analgesia as well as the incidence of postoperative complications following open colorectal cancer surgery. METHODS A three-year retrospective case note review was undertaken of all patients undergoing open colorectal cancer surgery at the Royal Devon and Exeter Hospital NHS Foundation Trust who received either EA or RSC for postoperative analgesia under the care of the senior authors. A single surgeon and single anaesthetist were practitioners. RESULTS The case notes of 120 patients were reviewed retrospectively: 85 patients had EA and 24 RSC while 11 patients were excluded from the study. The EA group experienced a significantly higher incidence of hypotension (systolic blood pressure <130mmHg) than the RSC group on the first postoperative day (p=0.0001). There was no significant difference in pain score or opiate sparing properties between the groups (p=0.92). There was no significant difference in postoperative respiratory tract infection, anastomotic leak or wound complications between the groups (p=0.2, p=1.0 and p=0.5 respectively). The RSC group had a higher incidence of ileus than the EA group (4/24 vs 2/85, p=0.026). However, the numbers were too small to draw a reliable conclusion. CONCLUSIONS The use of ultrasonography guided RSCs has demonstrated effective postoperative analgesia equivalent to EA with the potential benefits of a reduced incidence of hypotension. A prospective randomised trial is now underway to compare RSC and EA in open abdominal and pelvic surgery.In the UK, laparoscopic colorectal surgery is increasing. Nevertheless, a substantial proportion of surgery remains open.1 The accepted 'gold standard' technique for postoperative analgesia following open colorectal surgery is epidural analgesia (EA).2 The use of EA provides effective analgesia, and has the benefits of reducing systemic opiate requirements, ileus and pulmonary complications.3,4 Epidurals have reported complications that range from superficial wound site infection to paraplegia. 5-8The introduction of local nerve blocks in place of EA in open colorectal surgery has shown promising results.9,10 The use of regional blocks has been shown to provide effective postoperative analgesia and demonstrates opiate sparing properties. Furthermore, it has been shown to be safe and avoids the risk for potentially devastating complications of EA. Associated complications with the use of regional blocks include insufficient block, local anaesthetic toxicity and visceral puncture. However, the safety margin can be improved by the use of ultrasonography to guide insertion.11 A study looking at the opiate sparing effects of regional block (transverse abdominis plane) for right hemicolectomies has produced promising results. 12We aim to add to this body of evidence and expand on it by describing the analgesic effect of ultrasonography guided rectus sheath catheters (RSCs) compared with EA in op...

Background The multidisciplinary perioperative and anaesthetic management of patients undergoing pelvic exenteration is essential for good surgical outcomes. No clear guidelines have been established, and there is wide variation in clinical practice internationally. This consensus statement consolidates clinical experience and best practice collectively, and systematically addresses key domains in the perioperative and anaesthetic management. Methods The modified Delphi methodology was used to achieve consensus from the PelvEx Collaborative. The process included one round of online questionnaire involving controlled feedback and structured participant response, two rounds of editing, and one round of web-based voting. It was held from December 2019 to February 2020. Consensus was defined as more than 80 per cent agreement, whereas less than 80 per cent agreement indicated low consensus. Results The final consensus document contained 47 voted statements, across six key domains of perioperative and anaesthetic management in pelvic exenteration, comprising preoperative assessment and preparation, anaesthetic considerations, perioperative management, anticipating possible massive haemorrhage, stress response and postoperative critical care, and pain management. Consensus recommendations were developed, based on consensus agreement achieved on 34 statements. Conclusion The perioperative and anaesthetic management of patients undergoing pelvic exenteration is best accomplished by a dedicated multidisciplinary team with relevant domain expertise in the setting of a specialized tertiary unit. This consensus statement has addressed key domains within the framework of current perioperative and anaesthetic management among patients undergoing pelvic exenteration, with an international perspective, to guide clinical practice, and has outlined areas for future clinical research.
