Severity of oEsophageal Anastomotic Leak in patients after oesophagectomy: the SEAL score

Background

Anastomotic leak (AL) is a common but severe complication after oesophagectomy. It is unknown how to determine the severity of AL objectively at diagnosis. Determining leak severity may guide treatment decisions and improve future research. This study aimed to identify leak-related prognostic factors for mortality, and to develop a Severity of oEsophageal Anastomotic Leak (SEAL) score.

Methods

This international, retrospective cohort study in 71 centres worldwide included patients with AL after oesophagectomy between 2011 and 2019. The primary endpoint was 90-day mortality. Leak-related prognostic factors were identified after adjusting for confounders and were included in multivariable logistic regression to develop the SEAL score. Four classes of leak severity (mild, moderate, severe, and critical) were defined based on the risk of 90-day mortality, and the score was validated internally.

Results

Some 1509 patients with AL were included and the 90-day mortality rate was 11.7 per cent. Twelve leak-related prognostic factors were included in the SEAL score. The score showed good calibration and discrimination (c-index 0.77, 95 per cent c.i. 0.73 to 0.81). Higher classes of leak severity graded by the SEAL score were associated with a significant increase in duration of ICU stay, healing time, Comprehensive Complication Index score, and Esophagectomy Complications Consensus Group classification.

Conclusion

The SEAL score grades leak severity into four classes by combining 12 leak-related predictors and can be used to the assess severity of AL after oesophagectomy.

O61: TEXTBOOK SURGICAL OUTCOMES IN OESOPHAGO-GASTRIC CANCER: THE INFLUENCE OF NATIONAL KEY PERFORMANCE INDICATORS

Introduction

High quality surgery remains the cornerstone of treating oesophago-gastric malignancy. Recent work from the Dutch Upper-gastrointestinal Cancer Audit (DUCA) have defined ten surgical and perioperative ‘textbook’ parameters that correlate with improved overall survival. The aim of this project was to examine the proportion of patients attaining ‘textbook’ outcomes for oesophagectomy and gastrectomy in our unit before and after the introduction of national key performance indicators (KPIs).

Method

A retrospective review of all oesophagectomies and gastrectomies from January 2010 until June 2019 was performed. Clinical, pathological, perioperative, morbidity and mortality outcomes were recorded. 10 ‘textbook’ parameters were studied pre- and post-KPI introduction.

Result

269 and 284 patients underwent oesophagectomy and gastrectomy respectively, 167 pre-KPI and 386 post-KPI. There were no significant differences in age (67.6 vs 66.4 years, p=0.6), gender (71% male, 29% female vs 68% male, 22% female, p=0.48), ASA grade (p=0.6) or tumour stage (p=0.37) pre- and post-KPI. In the pre-KPI era, 28/167 (17%) patients achieved all ten textbook parameters, compared with 157/386, (41%, p=0.001) post-KPI. This compares favourably to DUCA ‘textbook’ data. There was an improvement in adequate lymphadenectomy (56% vs 83%, p=0.002), a reduction in margin positivity (21% vs 7%, p= 0.001) and peri-operative mortality (6% vs 2%, p=0.03) post-KPI.

Conclusion

There has been a significant improvement in perioperative outcomes in esophagectomy following the introduction of national KPIs in our unit. The number of patients achieving ‘textbook’ outcomes is comparable with international standards. The identification of textbook parameters allows further focus for future quality improvement initiatives.

Take-home message

National KPIs improve peri-operative outcomes in oesophago-gastric cancer.

Technical description of laparoscopic Morgagni hernia repair with primary closure and onlay composite mesh placement

INTRODUCTION

Morgagni hernias rarely present in adult life and, thus, little data exist on the optimal method of surgical repair. The laparoscopic approach has grown in popularity since the first reported case in 1992. This article showcases a method for laparoscopic repair of Morgagni hernias using both primary closure and mesh reinforcement.

OPERATIVE APPROACH

There were three obese women who presented in adulthood with cardiopulmonary symptoms; in all cases, the symptoms were attributable to local compressive effects of large Morgagni hernias. All three hernias were repaired laparoscopically, first by approximating the diaphragm to the fascia of the anterior abdominal wall, followed by insertion of a composite mesh, tacked to the diaphragm, to buttress the closure. All patients had excellent outcomes with symptom resolution.

DISCUSSION

This case series describes a method of laparoscopic Morgagni hernia repair using primary closure reinforced with a mesh, with excellent postoperative outcomes. Others have described thoracic or open approaches. The authors feel that the method described herein is likely to reduce recurrence in a patient population who are often overweight or obese and, thus, have a high risk of this complication. Furthermore, we discuss all reported laparoscopic repair cases in the literature and highlight the paucity of evidence on the optimal approach.

Laparoscopic Nissen fundoplication post-oesophageal stenting: an unusual case

Laparoscopic Nissen fundoplication post-oesophageal stenting is uncommon and yet to be reported. We report the case of a 57-year-old palliative lady who underwent surgery for symptomatic relief of severe gastrooesophageal reflux post-oesophageal stenting. Surgery was carried out successfully with no complications. On the evening post-surgery she was able to lie supine for the first time in months without symptoms of reflux. In conclusion, surgery is still valuable and may play an important role, even in a palliative setting.

We report the case of a 71-year-old gentleman who intially developed cutaneous metastases from gastric carcinoma on his chin and cheek resembling sebaceous cysts.

Thoracoscopic repair of instrumental perforation of the oesophagus: first report

BACKGROUND

Perforation of the oesophagus is a life-threatening condition requiring early recognition and repair to prevent mediastinitis and death. Primary closure with mediastinal drainage is recognised as the treatment of choice for patients presenting within 24 hours. Many are frail, however, and unsuitable for major surgery.

AIM

To report the first case of thoracoscopic repair of the oesophagus for oesophageal perforation following instrumentation.

METHODS

Flexible endoscopy revealed a 10cm perforation in the right lower oesophagus. With the gastroscope in the oesophagus, four thoracoports were introduced. Using suction and irrigation, the pleural cavity was suctioned free of debris and a 10cm longitudinal tear of the right lateral aspect of the oesophagus was repaired using interrupted polyglactin sutures through all layers.

RESULTS

The patient tolerated the procedure well and made an uncomplicated recovery.

CONCLUSION

The uncomplicated recovery of this frail patient without need for blood transfusions or assisted ventilation supports the notion that the thoracoscopic approach may have significant advantages. With increased experience and technical refinements there should be less reluctance to refer these patients for earlier definitive surgical repair.
