  8. Transhiatal Oesophagectomy (THO) • Originally described by Dent in 1913 • First performed by Turner in 1933 • Subsequently popularized by Orringer[1,2] • Pommier RF, Vetto JT, Ferris BL, et al. Relationships between operative approaches and outcomes in esophageal cancer. Am J Surg 1998; 175:422– 425. • Orringer MB, Marshall B, Iannettoni MD. Transhiatal esophagectomy: clinical experience and refinements. Ann Surg 1999; 230:392– 403.

  9. Ivor Lewis Oesophagectomy (ILO) • Combined abdominal and thoracic approach originally described by Ivor Lewis in 1946 [1] • Lewis I. The surgical treatment of carcinoma of the esophagus, with special reference to a new operation for growths of the middle third. Br J Surg 1946; 34:18 –31.

  10. THO vs ILO • It is argued that the transhiatal operation is less of a physiologic insult on the body. • Conversely, it is argued that THO violates basic surgical principles of adequate exposure and hemostasis, and that lymph node clearance is not as complete with THO as with ILO • Compare THO and ILO in terms of • Morbidity • 5 year survival • Disease free interval

  11. Morbidity • Anastamotic leak older studies… • Leak rates greater than 25% have previously been reported for THO, more than double that which is expected for ILO [1] • The consequences of a leak in the neck are far less disastrous than those with intrathoracic leaks, where mortality after a leak approaches 50% [2] • Vigneswaran, W.T., Trastek, V.F., Pairolero, P.C., Deschamps, C., Daly, R.C., Allen, M.S.: Transhiatal esophagectomy for carcinoma of the esophagus.

  12. Anastamotic leak continued… • Connors et al [1] • 17,395 patients (Nationwide Inpatient Sampling Database) • No difference in GI complications (including anastamotic complications) • Chang et al [2] • 225 THO vs 643 Transthoracic • Anastamotic complication rate higher in THO (43.1% vs 34.5%) but overall mortality similar between both groups • Contemporary studies demonstrated mortality for intrathoracic leaks comparable to cervical [3,4] • Connors RC et al.

N Engl J Med 2002;347:1662–9. • 220 patients with mid/distal adenocarcinoma • 106 THO • 114 TTO • Higher peri-operative morbidity after trans thoracic oesophagectomy • Pulmonary complication rate of 57% vs 27% (THO) • No difference in in-hospital mortality

Oesophagectomy by a transhiatalapproach or thoracotomy: a prospective randomized trial. Br JSurg 1993;80:367–70. 5 year survival

  16. Omloo JM, Lagarde SM, Hulscher JB, et al. Extended transthoracicresection compared withlimited transhiatal resection for adenocarcinomaof the mid/distal esophagus: five-yearsurvival of a randomizedclinical trial.Ann Surg 2007;246:992–1001. 95 patients underwent THO and 110 patients underwenttransthoracic oesophagectomy. After transhiatal andtransthoracic resection five-year survival was 34% and36% respectively In a subgroup analysis, no overallsurvival benefit for either surgical approach was seen in115 patients with a type II (tumour of the cardia) However, in 90 patients with a type I tumour (distal oesophagus) an absolute survival benefit of 14% was seen withthe transthoracic approach (51% vs. 37%, p0.33).

  17. Rizzetto C, DeMeester SR et al. En bloc esophagectomy reduces local recurrence and improves survival compared with transhiatal resection after neoadjuvant therapy for esophageal adenocarcinoma.J Thorac Cardiovasc Surg. 2008 Jun;135(6):1228-36 • 58 patients between 1992 – 2005 • Neoadjuvant Tx followed by surgery • “En Bloc” resection vs THO • 5 yr survival 51% vs 22% • Concluded that “en bloc” resection afforded a survival advantage in post neo-adjuvant patients

  18. No lymph nodes involved >8 lymph nodes 1-8 lymph nodes 5 year disease free survival Dependant on number of positive lymph nodes in resection [1]: Comparable locoregional disease free survival Locoregional disease free-survival advantage ifoperated via the transthoracic route (23% vs. 64%,p 0.02) • Omloo JM, Lagarde SM, Hulscher JB, et al.

Predicting systemic disease in patients with esophageal cancer after esophagectomy: a multinational study on the significance of the number of involved lymph nodes.Ann Surg 2008 Dec;248(6):979-85 • Multinational retrospective review • 700 Adenoca, 353 SCC undergoing oesophagectomy alone • Systemic disease recurrance: • 40% Overall • 16% if 0 Lymph nodes involved • 93% with >8 involved

  20. The future…? • Minimally invasive procedures increasingly adopted • UK study of 75 oesophagectomies comparing convention and minimally invasive ILO [1] • Laparoscopic appraoch associated with: • Reduced blood transfusion • Decreased operative time • Adequate lymph node harvest • Hamouda AH et al. Perioperative outcomes after transition from conventional to minimally invasive Ivor-Lewis esophagectomy in a specialized center. Surg Endosc 2009 Sep 3 [Epub ahead of print]

  21. Conclusions • In the short term, THO is is accompanied by less morbidity • In the long term, THO seems preferable onlyfor patients with: • Tumours located at the GOJ • Without suspected nodes in the upper compartmentof the chest • Post neoadjuvant patients or poor clinical condition • Transthoracic oesophagectomy: • Tumours located elsewhere in the oesophagus • Junctional tumours with suspectedlymph nodes high in the chest.
