Faculty Opinions recommendation of Patch repair of deep wounds by mobilized fascia.

Background: Single-port laparoscopic surgery (SPLS) is increasingly used in surgery and in the treatment of perforated duodenal ulcer. The aim of this study was to evaluate technical factors for perforated duodenal ulcer repair by SPLS. Methods: A prospective study on 42 consecutive patients diagnosed with perforated duodenal ulcer and treated with SPLS at Hue university of medicine and pharmacy hospital and Hue central hospital from January 2012 to February 2015. Results: The mean age was 48.1 ± 14.2 (17 - 79) years. 40 patients were treated with suture of the perforation by pure SPLS. There was one case (2.4%) in which one additional trocar was required. Conversion to open surgery was necessary in one patient (2.4%) in which the perforation was situated on the posterior duodenal wall. Two patients (4.8%) with history of abdominal surgery were successfully treated by pure SPLS. The size of perforation was correlated with suturing time (correlation coefficient r = 0.459) and operative time (correlation coefficient r = 0.528). Considering suture type, X stitches were used in 95.5% cases, simple stitches were used in one case (2.4%) while Graham patch repair technique was utilized in one case (2.4%) with large perforation. Most cases (95.1%) required only simple suture without omental patch. Peritoneal drainage was spared in most cases (90.2%). Conclusions: SPLS is a safe method for the treatment of perforated duodenal ulcer. Posterior duodenal location is the main cause of conversion to open surgery. Factor related to operative time is perforation size. Key words: perforated duodenal ulcer, single port laparoscopic repair, single port laparoscopy

Abstract Background The surgical treatment for postinfarction ventricular septal defect (VSD) remains challenging, especially in emergency cases. Several authors have reported the efficacy of a sandwich patch VSD repair via a right ventricular (RV) incision. However, this procedure remains uncommon, and its efficacy is still unknown, especially when performed under an emergency. Case summary We were able to perform sandwich patch VSD repair via an RV incision on seven consecutive patients with VSD following an ST-segment elevation myocardial infarction (STEMI) from March 2017 to December 2019. Bovine pericardial patches were used for sandwich patches. Two patients developed inferior STEMI, and the other patients developed anterior STEMI. Six patients received intra-aortic balloon pump prior to surgery, and the other received extracorporeal membrane oxygenation with Impella. The interval between the diagnosis of VSD and surgery was within 1 day in all patients except one (5 days). All seven patients underwent VSD repair in the emergency status. Four patients underwent concomitant coronary artery bypass grafting. The hospital mortality rate was 14.3% (1/7). Early postoperative transthoracic echocardiography revealed that only one patient developed more than trace residual shunt. The postoperative right atrial pressure was not significantly elevated at ≤12 mmHg in all patients. No patient developed early postoperative prolonged low cardiac output syndrome. Discussion In patients with postinfarction VSD, a sandwich patch VSD repair via an RV incision is a promising procedure with a low incidence of residual shunt development and hospital mortality, even in emergency cases.

Duct Ligation

Background Chylothorax is a rare form of pleural effusion that can be associated with both traumatic and non-traumatic causes. Very few patients respond to conservative line of therapy. Thoracic duct ligation is often the treatment of choice in post-surgical patients; however, the optimal treatment of this disease process after traumatic injury remains unclear. Case presentation: We present the case of a 46-year-old woman with thoracic duct injury secondary to decortication for post-pneumonic empyema. Conservative therapy and pleurodesis done twice failed. She developed severe cachexia losing 15 kg in 30 days. She was referred to our center for ligation of thoracic duct. Preoperative lymphangiography located the duct injury in upper part of mediastinum. Computerized tomography scan of chest showed collapse of left lower lobe and thickened left pleura, indicating a significant pericardial effusion. She underwent decortication of left lung, pericardial window, and native pericardial patch repair of thoracic duct. Results and Conclusions: In this unusual and complex case, successful resolution of the chyle leak was achieved with new surgical technique of patch repair. The patient recovered well and was now on a normal diet. She has put on 12 kg in four months. We have avoided late complications of thoracic duct ligation by this technique. This nouvelle technique may be recommended as it is simple and effective. Ligation of thoracic duct carries late complications. Isolating right lung by double lumen tube may cause severe hypoxia as left-sided lung is not expanded as in this case.
