We report a new method of esophagogastrostomy after proximal gastrectomy, side overlap with fundoplication by Yamashita (SOFY) in 2017. Recently, even better treatment results can be obtained by modifying the SOFY method. We describe the technical details of the modified SOFY (mSOFY) after laparoscopic proximal gastrectomy. The stomach was dissected in the short axis direction and the esophagus was dissected in the left and right direction. After the proximal gastrectomy, the bilateral diaphragmatic crus were dissected to enhance gastric elevation. After confirming that the esophagus overlapped more than 5 cm at the center of the remnant stomach (we call it SOFY check), the remnant stomach was suture‐fixed to the dissected diaphragmatic crus. The right wall of the esophageal stump and the remnant stomach were anastomosed using the full length of a 45 mm‐linear stapler. The entry hole was closed in a direction that did not widen the anastomotic hole. Both sides of the esophagus, remnant stomach, and diaphragmatic crus were suture‐fixed on the cranial side 1–2 cm away from the anastomosis. Moreover, the left wall and lower end of the esophagus was suture‐fixed to the remnant stomach. The preserved dorsal esophageal wall is pressed and flattened by pressure from the pseudofornix, which is the reflux prevention mechanism. The mSOFY method had favorable treatment outcomes. In conclusion, mSOFY can be one of the safe and feasible reconstruction methods after laparoscopic proximal gastrectomy.
Pancreatic cancer patients with para-aortic lymph node metastasis have a poor prognosis and patients living longer than 3 years are rare. We had a patient with pancreatic cancer who survived for more than 10 years after removal of the para-aortic lymph node metastasis. A 57-year-old woman was diagnosed with pancreatic head cancer and underwent a pancreaticoduodenectomy with subtotal gastric resection following Whipple reconstruction in 2000. Para-aortic lymph node metastasis was detected during the operation by intraoperative pathological diagnosis and an extended lymphadenectomy was performed with vascular skeletonization of the celiac and superior mesenteric arteries. In 2004, a low-density area was detected around the superior mesenteric artery (SMA) 5 cm from its root and she was treated with gemcitabine, and the area was undetectable after 3 years of treatment. In 2010, computed tomography showed a low-density area around the same lesion with an increased carcinoembryonic antigen level. After 4 months of gemcitabine treatment, we resected the tumor en bloc with the associated superior mesenteric vein and perineural tissue. Histopathological examination of the resected specimen revealed a well-differentiated tubular adenocarcinoma that closely resembled the original primary pancreatic cancer, indicating perineural recurrence 10 years after the initial resection. She had no recurrence around the SMA for more than one year. Although a meta-analysis has not proved the efficacy of preventive radical dissection, this case indicates that a patient with well-differentiated, chemotherapy-responsive pancreatic cancer with para-aortic lymph node metastasis could have a long survival time through extended dissection of the lymph nodes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
