Surgical Technique: Supraclavicular First Rib Resection.

Thoracic outlet syndrome is a condition of compression involving the brachial plexus and subclavian vessels. Although there are multiple surgical approaches to address thoracic outlet decompression, supraclavicular first rib resection with scalenectomy and brachial plexus neurolysis allow for complete exposure of the first rib, brachial plexus, and vasculature. This technique is described in detail. This approach is safe and can produce excellent outcomes in all variants of thoracic outlet syndrome.

Tracheal release maneuvers.

Tracheal resection and reconstruction has been slow to develop in the field of thoracic surgery. The ability to perform a low tension, well-vascularized anastomosis with good outcomes has improved with understanding of tracheal blood supply and the ability to perform tracheal release maneuvers. Laryngeal and suprahyoid release maneuvers can be helpful for cervical tracheal resections, while hilar and pericardial release maneuvers can be beneficial in thoracic tracheal resections. Simple maneuvers such as neck flexion and dissection of the avascular pretracheal plane can also be used to improve anastomotic tension. In this paper, we will review the indications, technical considerations and results of performing cervical and intrathoracic tracheal release maneuvers during tracheal resection and reconstruction.

Robotic esophagectomy.

Robotic esophagectomy is an increasingly used modality. Patients who are candidates for traditional, open esophagectomy are typically also candidates for robotic esophagectomy. Knowledge of and training on the robotic platform is critical for success. Patient and port positioning is described. Either a hand-sewn or stapled intrathoracic anastomosis may be performed. Minimally invasive esophagectomy (MIE) appears to be associated with decreased respiratory complications versus open esophagectomy. Robotic esophagectomy may be performed with excellent perioperative outcomes, though long-term oncologic data regarding the operation are not yet available.

Left upper lobectomy after coronary artery bypass grafting.

OBJECTIVE: Left upper pulmonary lobectomy or segmentectomy after coronary artery bypass grafting (CABG) risks injury to the grafts. We reviewed our experience. METHODS: This is a retrospective review of a prospective database from 1 surgeon, of patients who underwent left upper lobectomy after having previous CABG. RESULTS: Between June 1998 and June 2014, a total of 2207 patients underwent lobectomy by 1 surgeon; 458 (21%) had a left upper lobectomy, and 28 (6.1%) had had a previous CABG. Twenty-seven patients (96.4%) had a left internal mammary artery (LIMA) used for the bypass. Twenty-six patients (96.2%) had significant adhesions between their lung and the bypass grafts. Of patients who had a LIMA graft, 25 (92.6%) had the left upper lobe completely dissected free from their grafts, whereas 2 patients (7.1%) had a sliver of their lung left on the grafts. No patient had a postoperative myocardial infarction, and 30-day and 90-day survival rates were both 100%. All patients had a curative resection, and all had complete thoracic lymphadenectomy. CONCLUSIONS: Left upper lobectomy after CABG, in patients with previous CABG and LIMA grafting, is safe. Usually the entire lung can be safely mobilized off the bypass grafts; if needed, a small sliver of lung can be left on the grafts. A curative resection is possible with minimal perioperative cardiac morbidity, and excellent 30- and 90-day mortality.

Endoscopic ultrasound evaluation in the surgical treatment of duodenal and peri-ampullary adenomas.

AIM: To investigate endoscopic ultrasound (EUS) for predicting depth of mucosal invasion and to analyze outcomes following endoscopic and transduodenal resection. METHODS: Records of 111 patients seen at our institution from November 1999 to July 2011 with the post-operative pathological diagnosis of benign ampullary and duodenal adenomas were reviewed. Records of patients who underwent preoperative EUS for diagnostic purposes were identified. The accuracy of EUS in predicting the absence of muscular invasion was assessed by comparing EUS reports to the final surgical pathological results. In addition, the incidence of the post-operative complications over a period of 30 d and the subsequent long-term outcome (recurrence) over a period of 30 mo associated with endoscopic and transduodenal surgical resection was recorded, compared and analyzed. RESULTS: Among 111 patients with benign ampullary and duodenal adenomas, 47 underwent preoperative EUS for 29 peri-ampullary lesions and 18 duodenal lesions. In addition, computed tomography was performed in 18 patients, endoscopic retrograde cholangio-pancreatography in 10 patients and esophagogastroduodenoscopy in 22 patients. There were 43 patients with sporadic adenomas and 4 patients with familial adenomatous polyposis (FAP)/other polyposis syndromes. In 38 (81%, P < 0.05) patients, EUS reliably identified absence of submucosal and muscularis invasion. In 4 cases, EUS underestimated submucosal invasion that was proven by pathology. In the other 5 patients, EUS predicted muscularis invasion which could not be demonstrated in the resected specimen. EUS predicted tumor muscularis invasion with a specificity of 88% and negative predictive value of 90% (P < 0.05). Types of resection performed included endoscopic resection in 22 cases, partial duodenectomy in 9 cases, transduodenal ampullectomy with sphincteroplasty in 10 cases and pancreaticoduodenectomy in 6 cases. The main post-operative final pathological results included villous adenoma (n = 5), adenoma (n = 8), tubulovillous adenoma (n = 10), tubular adenoma (n = 20) and hyperplastic polyp (n = 2). Among the 47 patients who underwent resection, 8 (17%, 5 of which corresponded to surgical resection) developed post-procedural complications which included retroperitoneal hematoma, intra-abdominal abscess, wound infection, delayed gastric emptying and prolonged ileus. After median follow-up of 20 mo there were 6 local recurrences (13%, median follow-up = 20 mo) 4 of which were in patients with FAP. CONCLUSION: EUS accurately predicts the depth of mucosal invasion in suspected benign ampullary and duodenal adenomas. These patients can safely undergo endoscopic or local resection.
