Total Abdominal Wall Reconstruction with Component Separation, Reinforcement, and Vertical Abdominoplasty in Patients with Complex Ventral Hernias.

UNLABELLED: Large complex ventral hernias act as tissue expanders for skin and subcutaneous fat. The purpose of this study is to evaluate outcomes of total abdominal wall reconstruction with component separation, posterior reinforcement, and vertical abdominoplasty in patients with large complex ventral hernias. Between 2010 and 2014, 58 patients underwent total abdominal wall reconstruction with component separation, intra-abdominal reinforcement, and vertical abdominoplasty. Between 2010 and 2012, patients underwent the conventional technique of component separation, while a perforator-preserving technique was performed during 2013 and 2014. Reinforcement material used was either synthetic mesh in clean cases or biologic mesh if contamination was present. All of the excessive skin and subcutaneous fat was removed in a vertical fashion. Data were analyzed with Mann-Whitney's U test or Fisher's exact test, as indicated. There were 27 moderately complex and 31 majorly complex hernias. Mean hernia size was 16 × 12 cm. The mean size of the removed skin island was 21 × 12 cm. Patients with contamination during the repair had longer in-hospital stays. Overall the local wound complication rate was 24 %, and was lower with the perforator-preserving technique compared to the conventional technique of component separation (11 vs. 48 %; OR 0.13, CI 0.03-0.5; p = 0.003). The overall postoperative morbidity rate was higher in the presence of contamination, and in patients with lower preoperative serum albumin levels. Mean total follow-up was 14 months with a 1-year recurrence-free survival of 96 %. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

Surgical treatment for achalasia of the esophagus: laparoscopic heller myotomy.

Achalasia is an esophageal motility disorder that leads to dysphagia, chest pain, and weight loss. Its diagnosis is clinically suspected and is confirmed with esophageal manometry. Although pneumatic dilation has a role in the treatment of patients with achalasia, laparoscopic Heller myotomy is considered by many experts as the best treatment modality for most patients with newly diagnosed achalasia. This review will focus on the surgical treatment of achalasia, with special emphasis on laparoscopic Heller myotomy. We will also present a brief discussion of the evaluation of patients with persistent or recurrent symptoms after surgical treatment for achalasia and emerging technologies such as LESS, robot-assisted myotomy, and POEM.

Improvement results in paraesophageal hernia.

Paraesophageal hernias account for between 5 and 14% of hiatal hernias. Surgical management is complex and is currently one of the most debated subjects in surgery. Every symptomatic patient with a paraesophageal hernia and no contraindication for surgery should undergo repair. It is important to perform an evaluation that includes medical history, chest x-rays, barium swallow, upper endoscopy and manometry. Surgical approaches include open thoracic and abdominal access. Recently, laparoscopic surgery has become an option with less morbidity and mortality with results similar to open surgery. Essential technical aspects to improve results are reduction of the hernia sac, recognition and management of the short esophagus, hiatal closure and an antireflux procedure. Despite improving recurrence rates, use of synthetic mesh for hiatal closure has been associated with catastrophic complications; therefore, use of biologic mesh is preferred.
