Minimally Invasive Ivor-Lewis Esophagectomy for Esophageal Cancer After Gastric Bypass.

The increasing prevalence of morbid obesity in the United States has been accompanied by a concomitant rise in bariatric surgery to help combat the epidemic. The relationship between obesity and certain cancers, such as esophageal adenocarcinoma, is well established. The need for minimally invasive techniques to treat esophageal cancer in patients with previous bariatric surgery is growing and can present a unique surgical challenge. This report presents the case of a 55-year-old woman with a previous Roux-en-Y gastric bypass who was shown by endoscopy to have an invasive adenocarcinoma located in the distal thoracic esophagus. This necessitated an excision of the thoracic esophagus and the gastric pouch. A laparoscopic and thoracoscopic Ivor-Lewis esophagogastrectomy was performed for this complex patient with esophageal adenocarcinoma. The remnant stomach was fashioned into a gastric conduit using a 60-mm linear stapler with a staple height of 4.1 mm (Echelon, Ethicon Endosurgery, Blue Ash, OH). The reconstruction was performed using a 25-mm Orvil (Covidien, Minneapolis, MN, USA) and EEA 25-mm DST XL (Covidien) to create a circular stapled thoracic esophagogastric anastomosis. A feeding jejunostomy was placed in the residual 130-cm Roux limb. The study demonstrated that minimally invasive esophagectomy is safe and technically feasible with appropriate oncologic outcomes for patients with previous gastric bypass. This cohort of patients will undoubtedly continue to grow in the coming years.

Minimally invasive Ivor-Lewis esophagectomy for esophageal cancer with right aortic arch.

Right aortic arch (RAA) is a rare congenital vascular abnormality in which the aorta descends in the right thorax and encircles the esophagus. Historically, esophagectomy for patients for RAA is done through a left thoracotomy as exposure and mobilization of the esophagus is difficult through a right thoracotomy. A 73-year-old male was found to have an esophageal adenocarcinoma. Endoscopic ultrasound showed a T3N0 lesion in the lower third of the esophagus. PET CT demonstrated a circumferential lesion without evidence of distant disease or involved lymph nodes and a RAA which was not associated with congenital heart disease or symptoms. The patient received neo-adjuvant chemoradiation (50.4 Gy) with carboplatin and paclitaxel. Minimally invasive Ivor-Lewis esophagectomy (MIE) utilizing conventional right thoracoscopy was done. Esophageal mobilization, transection and mediastinal lymph node dissection was performed through anteriorly placed trocars, thereby avoiding the right side descending aorta that is lying anterior and to the right of the esophagus. In this video we demonstrate MIE utilizing right thoracoscopy. Total operative time was 250 minutes and the patient was discharged home on post-operative day 8. Final pathology showed complete pathological response, with 0/22 involved lymph nodes and uninvolved surgical margins. Minimally invasive esophagectomy has been reported to deliver superior outcomes to the open approach. MIE can be performed in selected patients with RAA, and herein we demonstrate a minimally invasive option for the treatment of distal esophageal cancer in patients with RAA. To our knowledge this is the 1st reported case in the English literature utilizing this approach in patient with RAA.

Thoracoscopic management of volvulus of the gastric conduit following minimally invasive Ivor-Lewis esophagectomy.

BACKGROUND: We present a case of emergent thoracoscopic management of volvulus of the gastric conduit following minimally invasive Ivor-Lewis esophagectomy. The patient is a 69-year-old Caucasian male with a history of adenocarcinoma of the lower third of the esophagus. Initial presentation was dysphagia with solid foods, which progressed in severity until he was unable to swallow anything. EUS demonstrated a partially obstructing mass at 33 cm; biopsy revealed poorly differentiated adenocarcinoma, stage T3N2Mx. PET scan did not reveal any metastatic disease. Preoperative management included neo-adjuvant chemoradiation therapy (5-FU and cisplatin) and early placement of a jejunal feeding tube. Intra-operative leak test was performed as a matter of routine following completion of the esophagogastric anastomosis. A nasogastric tube was placed intra-operatively and removed on POD2 according to our standard pathway. Postoperatively, the patient progressed without difficulty to POD4, when we routinely obtain an upper GI swallow study. This demonstrated a lack of transit of contrast through the distal neo-esophagus. Follow-up endoscopy revealed volvulus of the gastric conduit with obliteration of the lumen. METHOD: We immediately took the patient to the OR for thoracoscopic detorsion, which we accomplished successfully by entering the existing trochar sites and using blunt dissection.␣Upon entering the thoracic cavity, the staple line that had been oriented anteriorly was now posterior. Attachments were gently teased away from the chest wall and the conduit was detorsed and anchored to the chest wall in the correct orientation with silk suture. Intra-operative endoscopy demonstrated a patent conduit. RESULTS: Postoperative upper GI fluoroscopy now showed good transit of contrast. The patient continued to improve and was eventually advanced to mechanical soft diet and discharged on postoperative day 9. CONCLUSIONS: Early intervention is indicated in cases of volvulus of the gastric conduit following Ivor-Lewis esophagectomy.

Laparoscopic repair of paraesophageal hernias.

BACKGROUND AND OBJECTIVES: Laparoscopy has quickly become the standard surgical approach to repair paraesophageal hernias. Although many centers routinely perform this procedure, relatively high recurrence rates have led many surgeons to question this approach. We sought to evaluate outcomes in our cohort of patients with an emphasis on recurrence rates and symptom improvement and their correlation with true radiologic recurrence seen on contrast imaging. METHODS: We retrospectively identified 126 consecutive patients who underwent laparoscopic repair of a large paraesophageal hernia between 2000 and 2010. Clinical outcomes were reviewed, and data were collected regarding operative details, perioperative and postoperative complications, symptoms, and follow-up imaging. Radiologic evidence of any size hiatal hernia was considered to indicate a recurrence. RESULTS: There were 95 female and 31 male patients with a mean age (±standard deviation) of 71±14 years. Laparoscopic repair was completed successfully in 120 of 126 patients, with 6 operations converted to open procedures. Crural reinforcement with mesh was performed in 79% of patients, and 11% underwent a Collis gastroplasty. Fundoplications were performed in 90% of patients: Nissen (112), Dor (1), and Toupet (1). Radiographic surveillance, obtained at a mean time interval of 23 months postoperatively, was available in 89 of 126 patients (71%). Radiographic evidence of a recurrence was present in 19 patients (21%). Reoperation was necessary in 6 patients (5%): 5 for symptomatic recurrence (4%) and 1 for dysphagia (1%). The median length of stay was 4 days. CONCLUSION: Laparoscopic paraesophageal hernia repair results in an excellent outcome with a short length of stay when performed at an experienced center. Radiologic recurrence is observed relatively frequently with routine surveillance; however, many of these recurrences are small, and few patients require correction of the recurrence. Furthermore, these small recurrent hernias are often asymptomatic and do not seem to be associated with the same risk of severe complications developing as the initial paraesophageal hernia.

Laparoscopic splenectomy to salvage renal transplants from severe acute antibody-mediated rejection.

Purpose. Acute antibody-mediated rejection, a complication of cross match positive and sensitized renal transplants, occurs despite the use of standard desensitization protocols. Rescue therapy consists of plasmapheresis and intravenous immunoglobulin (IVIg). In patients with preformed donor specific antibodies, rejection can be aggressive. We report here a case in which laparoscopic splenectomy was added to the standard rescue regimen. Case Report and Results. A 40-year-old Hispanic female with end stage renal disease had been receiving hemodialysis. The patient had numerous class 1 unacceptable antigens. She was scheduled to undergo an incompatible 1-1-1 mismatch living related donor kidney transplant. Preoperatively, the patient received plasmapheresis, IVIG, and thymoglobulin. There was good graft function until postoperative day 5. At that point, worsening renal function was noted. Renal biopsy was consistent with AMR. The patient became anuric and dialysis was initiated. To salvage the transplant, the patient underwent laparoscopic splenectomy. Postoperatively, renal function improved. Two years after transplant, the patient continues to have excellent graft function. Conclusion. In a small but significant number of renal transplants, antibody production occurs at a rate that traditional treatments are unable to reduce effectively. Based on our experience, the addition of splenectomy to standard rescue therapy can salvage renal transplants.
