[Hiatus calibration decreases postoperative dysphagia after laparoscopic fundoplication: case-report study]. / Le calibrage de l'orifice hiatal diminue la dysphagie postopératoire après la cure de reflux gastro-oesophagien par laparoscopie: étude cas-témoins.

STUDY AIM: The risk of dysphagia after antireflux surgery seems to be increased with laparoscopy compared with open surgery. Calibration of the hiatus is usually done by the surgeon's finger during open surgery. The aim of this study was to assess the results of laparoscopic calibration with a Fogarty balloon catheter. PATIENTS AND METHODS: Between 1999 and 2001, 21 patients had a laparoscopic Toupet 240 degrees fundoplication with hiatus calibration using a 4 ml-inflated 8G Fogarty balloon catheter. These patients were compared with a group of 21 patients without hiatus calibration, matched for age, sex, preoperative dysphagia and esophageal dysmotility. Judgment criteria was early and/or late postoperative dysphagia (> 3 months). RESULTS: Median follow-up was 13 months. The rate of early dysphagia with and without calibration were 66% and 48% respectively (NS). Median duration of early dysphagia with and without calibration were 25 and 43 days respectively (p = 0.05). No patient with calibration had late dysphagia. One patient (5%) without calibration had unexplained late dysphagia for 2 years. He had preoperative esophageal dysmotility without oesophagitis. CONCLUSION: Hiatus calibration with a Fogarty balloon catheter decreased early postoperative dysphagia duration after Toupet laparoscopic fundoplication. This easily reproducible technical point standardizes the hiatus closure and should be recommended.

Thoracoscopic resection of pulmonary nodules after computed tomographic-guided coil labeling.

BACKGROUND: A limiting factor in performing video-assisted thoracic surgery for resection of peripheral solitary pulmonary nodules has been the recognition of the lesion visually. This study reports our clinical experience of injecting a small metallic marker under computed tomographic scan guidance before the operation, allowing localization of the lesion. METHODS: A series of 14 patients underwent video-assisted thoracic surgery for removal of 15 pulmonary nodules situated in the outer third of the lung. Before operation, a radiopaque microcoil was injected just behind the lesion and then used to locate, under fluoroscopy, the area to be resected during thoracoscopy. The technique was evaluated for accuracy, reliability, and ease of use. RESULTS: Microcoil labeling of peripheral pulmonary nodules allowed in every case a complete resection and a histologic identification of the lesion. It is more stable and accurate than methylene blue dye marking, and it is as easy to perform as computed tomographic scan-guided biopsy. The incidence of complication was small in spite of our inexperience with the technique. CONCLUSIONS: Our experience with microcoil injection shows that it provides consistent and highly accurate marking of pulmonary nodules for video-assisted thoracic surgery, allowing secure resection with a safe margin.
