Patients exposed to a surgical safety checklist experience better postoperative outcomes, but this could simply reflect wider quality of care in hospitals where checklist use is routine.

Post-operative AF was associated with poorer long-term survival following oesophagectomy in this cohort. Further research should evaluate the influence of AF on cardiovascular and oncological outcomes following oesophagectomy.

Background: Oesophagectomy for locally advanced cancer carries high rates of morbidity and mortality. Patients require a thorough risk assessment alongside preoperative counselling. Total psoas area (TPA) measurements have been used as a surrogate marker of sarcopenia to predict post-operative complications in oesophageal cancer patients. No studies to date have determined whether there is an association between the proportion of TPA lost during neoadjuvant therapy and post-operative outcomes. Methods: Clinical data and imaging of patients who underwent neoadjuvant therapy followed by open two-stage oesophagectomy between January 2008 and April 2018 were analysed retrospectively. Patients who did not undergo restaging computed tomography scan prior to surgery were excluded from the study. The TPA was measured on two crosssectional slices at L4 on computed tomography scans pre-and post-neoadjuvant therapy. Results: A total of 53 patients who met inclusion criteria were identified. The mean loss of TPA was 7.3%. Patients who had a decrease of TPA of more than 4% had significantly increased 30-day mortality compared to those who lost 4% or less (24% versus 0%, P = 0.02). Patients aged over 65 years who also had a loss of TPA >4% had significantly increased 30-day mortality (37% versus 2.9%, odds ratio 19, P = 0.008). Conclusion: A decrease in TPA of >4% is associated with a significantly higher risk of post-operative mortality in patients undergoing neoadjuvant therapy followed by oesophagectomy. Measuring the loss of TPA during neoadjuvant treatment could be a novel aid to preoperative risk assessment.

A previously published study regarding the outcomes of oesophagectomy at a provincial hospital identified issues with perioperative care (Al-Herz et al 2012). The aim of this study was to evaluate the effect of changes in management at the institution concerned. This was a cohort study which compared the outcomes of 30 patients undergoing oesophagectomy before the unit audit and 30 patients after it. Demographics, operative details, recovery parameters, and oncological data were collected retrospectively. There was a significant reduction in the use of intravenous fluid, both intraoperatively (6.6 vs 3.3L, P < 0.0001) and during the first 24 hours (9.2 vs 5.5L, P < 0.0001). Patients were extubated three days earlier (P < 0.001) after the audit, and the percentage of patients requiring tracheostomy was smaller (26.7% vs 0%, P = 0.003). The length of total hospital stay was shorter (15 vs 13 days, P = 0.035). We conclude that the publication of a unit audit changed perioperative practice and resulted in a significant improvement in the short term outcomes after oesophagectomy.

Background The Clavien–Dindo classification is perhaps the most widely used approach for reporting postoperative complications in clinical trials. This system classifies complication severity by the treatment provided. However, it is unclear whether the Clavien–Dindo system can be used internationally in studies across differing healthcare systems in high‐ (HICs) and low‐ and middle‐income countries (LMICs). Methods This was a secondary analysis of the International Surgical Outcomes Study (ISOS), a prospective observational cohort study of elective surgery in adults. Data collection occurred over a 7‐day period. Severity of complications was graded using Clavien–Dindo and the simpler ISOS grading (mild, moderate or severe, based on guided investigator judgement). Severity grading was compared using the intraclass correlation coefficient (ICC). Data are presented as frequencies and ICC values (with 95 per cent c.i.). The analysis was stratified by income status of the country, comparing HICs with LMICs. Results A total of 44 814 patients were recruited from 474 hospitals in 27 countries (19 HICs and 8 LMICs). Some 7508 patients (16·8 per cent) experienced at least one postoperative complication, equivalent to 11 664 complications in total. Using the ISOS classification, 5504 of 11 664 complications (47·2 per cent) were graded as mild, 4244 (36·4 per cent) as moderate and 1916 (16·4 per cent) as severe. Using Clavien–Dindo, 6781 of 11 664 complications (58·1 per cent) were graded as I or II, 1740 (14·9 per cent) as III, 2408 (20·6 per cent) as IV and 735 (6·3 per cent) as V. Agreement between classification systems was poor overall (ICC 0·41, 95 per cent c.i. 0·20 to 0·55), and in LMICs (ICC 0·23, 0·05 to 0·38) and HICs (ICC 0·46, 0·25 to 0·59). Conclusion Caution is recommended when using a treatment approach to grade complications in global surgery studies, as this may introduce bias unintentionally.

Small bowel adenocarcinoma (SBA) is rare cancer that accounts for less than 2% of all gastrointestinal tract cancers. Usually, the clinical presentation is unspecific, and a patient might complain of nausea, vomiting, abdominal pain, small bowel obstruction, and small bowel bleeding. Because of these unspecific symptoms, the patient might be diagnosed late, from six to ten months, which affects the prognosis. This study contains a case report of a 38-year female with SBA in the jejunum, with unspecific symptoms. She had a history of recurrent admissions due to acute pancreatitis, acute kidney injury, and hyponatremia caused by dehydration. The patient was diagnosed six months after the first symptoms of nausea and vomiting started. The patient underwent exploratory laparotomy for a jejunal stricture mass, and a lymph node was resected. The course after surgery was smooth, and the patient was discharged home on the fourth-day post-surgery. In conclusion, the symptoms of SBA are unspecific and cannot be diagnosed without complete medical histories and lab examinations, making diagnosing SBA challenging.
