Comparative Study
A prospective comparison of totally minimally invasive versus open Ivor Lewis esophagectomy.
The majority of esophagectomies in Western parts of the world are performed by a transthoracic approach reflecting the prevalence of adenocarcinoma of the lower esophagus or esophagogastric junction. Minimally invasive esophagectomy (MIE) has been reported in a variety of formats, but there are no series that directly compare totally minimally invasive thoracolaparoscopic 2 stage esophagectomy (MIE-2) with open Ivor Lewis (IVL). A prospective single-center cohort study of patients undergoing elective MIE-2 or IVL between January 2005 and November 2010 was performed. ⋯ Blood loss was significantly less for MIE-2 compared with IVL (median 300 [range 0-1250] mL vs. 400 [range 0-3000] mL, respectively, P= 0.021). MIE-2 in this series of selected patients supports its efficacy, when performed by an experienced minimally invasive surgical team. A well-designed multicenter trial addressing clinical effectiveness is now required.

The development of achalasia in a patient with a history of esophageal atresia (EA) is rare. Here, we report a patient who had undergone surgery for EA at birth and presented achalasia at 30 years of age. He was successfully treated with laparoscopic surgery.

Common hepatic artery lymph node dissection is regarded as a standard procedure in esophageal cancer surgery because of aggressive lymphatic dissemination of esophageal cancer. However, lymph node dissection can prolong operation time and may be associated with complications such as chylous ascites. Here, we aimed to evaluate the effectiveness of common hepatic artery lymph node dissection in clinical T1N0 thoracic esophageal squamous cell carcinoma. ⋯ In-hospital mortality was one, and 5-year survival rate was 80.6%. Among the 15 patients with recurrence, there were two distant metastases and five distant and local recurrences but no intra-abdominal recurrence with common hepatic artery lymph node. Common hepatic artery lymph node dissection may be safely omitted in surgery for clinical T1N0 esophageal squamous cell carcinoma when preoperative evaluations including chest computed tomography, positron emission tomography and computed tomography, and esophagogastroduodenoscopy or endoscopic ultrasound are performed.

Carcinoma of the esophagus is classified according to the Union for International Cancer Control (UICC) TNM staging system. The 7th edition of the UICC TNM staging system was published in 2009. This is the first study to compare the prognostic value of the TNM 6th and 7th editions in patients with esophageal carcinoma treated with chemotherapy followed by surgery. ⋯ Survival probability was significantly different between ypN0 and ypN1 (P= 0.001 for TNM 6th and 7th edition), as well as ypN2 and ypN3 (TNM 7th edition, P= 0.004), but not between ypN1 and ypN2 (TNM 7th edition, P= 0.89). Neither the TNM 6th nor 7th edition T staging provides accurate survival probability stratification. However, the advantage of the 7th edition is the introduction of a third tier in survival stratification for patients with nodal involvement.

Esophageal foreign body impaction (EFBI) often requires urgent evaluation and treatment, but characteristics of emergency department (ED) care such as timing of presentation and therapeutic procedures and costs of care are unknown. We aimed to study health-care utilization for patients with EFBI presenting to the ED. Cases of EFBI from 2002 to 2009 were identified by querying three different databases from the University of North Carolina Hospitals for all records with ICD-9 CM code 935.1: 'foreign body in the esophagus.' Charts were reviewed to confirm EFBI and extract pertinent data related to the ED visit, including time of presentation, length of ED stay, medications administered, type of procedure performed, characteristics of procedures, and time to therapeutic procedure. ⋯ Medical management was largely ineffective. A therapeutic procedure was required to clear the EFBI in most patients. Time of ED arrival made no difference in time-to-procedure, indicating that gastroenterology and ENT specialists recognize the urgency of treating EFBI regardless of time of day.
