RESUMO

BACKGROUND/AIMS: Laparoscopic total gastrectomy (LTG) has not gained widespread acceptance because of the difficult reconstruction technique, especially for esophagojejunostomy. Although various modified procedures using a circular stapler for esophagojejunostomy have been reported, an optimal technique has not yet been established. In addition, in intracorporeal techniques, twisting of the esophagojejunostomy, which might be the cause of stenosis, is often encountered because application of the shaft is restricted. To prevent twisting of the esophagoejunostomy, we underwent LTG with Roux-en-Y reconstruction with its efferent loop located at the left side of the patient. METHODOLOGY: From November 2013 to November 2014, a series of 9 patients underwent LTG with Roux-en-Y reconstruction using the transorally inserted anvil (OrVil™, Covidien, Mansfield, MA, USA), whose efferent loop was located at the left side of the patient. RESULTS: No twisting of the esophagojejunostomy was encountered in all cases. In addition, no stenosis or leakage of the esophagojejunostomy occurred. CONCLUSIONS: This reconstruction system may be a feasible surgical procedure in LTG.

RESUMO

In totally laparoscopic distal gastrectomy (TLDG) for gastric cancer, accurately determining the proximal resection line may be difficult. This is because identifying the lesion intracorporeally is impossible, due to the lack of tactile sense, and, in addition, unlike the intestine, the most proximal site of the lesion is often different from the main site due to the distorted shape of the stomach. The aim of this study was to introduce a novel method of preoperative endoscopic marking with India ink, taking into consideration the morphological characteristics of the stomach. Between July, 2013 and April, 2016, 20 patients who underwent TLDG were enrolled in this study. Within the 3 days preceding the operation, after identifying the most proximal site of the lesion on the overlooking image of an endoscope, India ink was injected into the spot on the oral side of this site. The stomach was transected along the proximal border of the marked area. In all cases, the marked sites were localized and clearly identified during the operation, and the proximal resection margins were found to be negative on postoperative pathological examination. The mean length of the proximal margin was 46.0±14.0 mm. In conclusion, this preoperative endoscopic marking method may be useful in TLDG for gastric cancer.
