Case Presentation Afebrile, BP 130/76, PR 74 General- Cachexia, not pale, anicteric Abd- soft, NT/ND Chest- CTA bilat CVS-S1S2 no murmur Labs CBC 7/10/32/323 BMP- 143/4/107/25/51/1.69/114 Coagulation- 11.6/30/1
CT Scan Chest
Barium swallow
PET Scan
Case Presentation Ct Scan Chest- 3 cm soft tissue mass in mid-esophagus. Barium swallow- infiltrative circumferential narrowing of the esophagus suggestive of esophageal CA. PET Scan- Circumferential thickening of the mid esophagus with neoplastic range uptake EUS/ biopsy- Squamous cell CA
Case Presentation Pre-operative testing revealed 80% stenosis LAD Bare-metal stent inserted on 7/16/12. Elective surgery planned Re-admitted twice with worsening intolerance to liquids and solids and acute renal insufficiency on 7/25.
Case Presentation Tumor board multidisciplinary meeting 1. Surgery with adjuvant Chemoradiation 2. Neoadjuvant chemoradiation with Surgery - Similar outcomes with either options Plan was for Transhiatal Esophagectomy
Operative technique Abdominal phase Midline supraumbilical incision Identification and protection of right gastro-epiploic artery Gastric mobilization Kocher maneuver Pyloromyotomy Distal esophageal mobilization Feeding jejunostomy
Cervical phase
Mediastinal dissection
Resection and anastomosis
Hospital course POD#1- Extubated POD#3- Chest tube removal POD#7- Barium swallow: small contained leak Adjuvant Chemo-radiation planned
Pathology Poorly differentiated squamous cell carcinoma Proximal and distal margins are negative for carcinoma Lymphovascular and perineural invasion 3/7 lymph nodes positive pt3n2mx
History of esophageal resection Czerny 1877-1 st esophageal resection for cervical tumor Torek 1911- resection of thoracic esophagus Dent 1913-1 st Transhiatal esophagectomy in cadavers Turner 1933- transhiatal esophagectomy for carcinoma Oshawa 1933- Thoracic resection with anastomosis Ivor Lewis 1946- Ivor Lewis esophagectomy
Epidemiology Incidence in the United States is 20 per 100,000 Worldwide incidence : 160 per 100,000 2 major histological types Squamous cell carcinoma 70% found in upper & middle third Most common worldwide Adenocarcinoma Distal third Most common in western world
Clinical presentation Asymptomatic Dysphagia (74%) Retrosternal chest pain Weight loss (57%) Hoarseness Aspiration pneumonia
Diagnosis Esophagogram Upper endoscopy CT scan chest/abdomen/pelvis Endoscopic US and biopsy PET scan - Resectability
Pre-operative Assessment Evaluate physiologic status Cardiac and pulmonary status PFTs Non invasive cardiac evaluation Nutritional status
Transhiatal Esophagectomy Better surgical option for patients with poor pulmonary function Contraindications Severe CAD or valvular disease Bulky tumors of mid-esophagus difficult to dissect
Transhiatal Esophagectomy
Ivor Lewis Esophagectomy Laparotomy Right thoracotomy Anastomosis made in the chest Contraindications Tumors in upper third esophagus Long segment Barrett s with extension into cervical esophagus
IVOR LEWIS ESOPHAGECTOMY
Modified McKeown/Triincisional technique Combination of Ivor Lewis and transhiatal approaches Laparotomy Right thoracotomy Cervical anastomosis Useful for tumors at any level in the esophagus
En Bloc Resection Extensive lymphadenectomy Tri-incisional Ligation of azygos, hemi-azygos, intercostal veins Removal of mediastinal lymph nodes Excision rim of diaphragm Removal of pericardial, left gastric, portal, common hepatic, celiac, splenic lymph nodes Cervical esophago-gastric anastomosis
Follow up EGD every 3months for 1 st year and then annually History and Physical Examination every 3months for the 1 st 2years and then annually CT Chest /Abdomen every 6months for 1 st 2years and then annually till 5yrs
Conclusion Esophageal cancer remains a challenging disease with poor outcomes regardless of the stage. Surgery remains pivotal in its management. There is no single best practice. Multimodal therapy remains the optimal treatment.
