OPEN RYGB LONG-TERM COMPLICATIONS: VENTRAL HERNIA - REPORT ON A 10-YEAR SINGLE-CENTER EXPERIENCE.

Aim of Study - we hypothesize if there are any apparent risk stratifications to the abdominal wall compromise after open Roux-en-Y gastric bypass (RYGB) surgery and if the outcomes of retromuscular sublay mesh repair using Rives/Stoppa's technique were different from the literature. Description of a 10-year experience of a single center using sublay retromuscular mesh hernia repair in patients with ventral hernia after RYGB, including a total of 189 patients. 149 (78.8%) patients were women. Mean age of 47.3±10.9 years. 171 (90.48%) patients had at least one comorbidity, being systemic arterial hypertension the most prevalent (74.26%). The most frequent location of hernias was in the epigastric region with 125 cases (66.1%), followed by umbilical, inferior and subcostal (28.4%; 3.6%; 1.8%). The mean BMI of patients undergoing bariatric surgery was 50.2±6.6 kg/m². 112 (59.26%) patients within the ventral hernia sample had a BMI higher than 50 kg/m² before the bariatric surgery. The average length-of-stay at the hospital was 2.6 days. There were 17 (9%) cases of hernia recurrence. BMI>50 kg/m² and female sex may be risk factor to incisional ventral hernia in patients after open Roux-en-Y gastric bypass. Retromuscular sublay mesh appliance using Rives/Stoppa's technique had low length-of-stay of hospitalization and hernia recurrence compared to the literature.

Robotic repair of post-oesophagectomy hiatal hernia.

Diaphragmatic hiatal hernia is a potential complication of oesophagectomy in cancer patients. Over the past decades, laparoscopy has become the preferred approach to repairing this condition due to the reduced morbidity, faster recovery and shorter hospital stay when compared with traditional open surgery. The development of robotic technology has added to the benefits of minimally invasive approaches, offering potential technical advantages and overcoming some limitations of traditional laparoscopic techniques when performing complex procedures. We present the first report of a robotic post-oesophagectomy hiatal hernia repair.
