Postoperative functional evaluation of pylorus-preserving gastrectomy for early gastric cancer compared with conventional distal gastrectomy

Gastric motility after laparoscopically assisted distal gastrectomy, with or without preservation of the pylorus, for early gastric cancer, as assessed by digital dynamic x-ray imaging

“…7. Dynamic coronal images every 2 s from a case of laparoscopically assisted gastrectomy without pylorus preservation (LADG) [1][2][3][4][5][6]. Measurement of contraction amplitude, frequency, and motility index.…”

“…Imada et al [6] found that in most patients who underwent pylorus-preserving gastrectomy, gastric emptying was delayed 1 month after the operation. In our study, 11.5 % (3/26) of the patients who underwent LAPPG had remnant gastric stasis.…”

Current Status of Pylorus‐Preserving Gastrectomy for the Treatment of Gastric Cancer: A Questionnaire Survey and Review of Literatures

“…In many reports about PPG, techniques for the preservation of the celiac and/or hepatic and pyloric branches of the vagus have been described [8,15,16,[19][20][21], but few studies compared the clinical results between groups with and without vagal preservation. Tomita et al [22] reported that the incidence of gallstone disease in patients with preservation of hepatic and pyloric branches was less than those in whom these vagal branches were not preserved.…”

Pylorus-preserving gastrectomy in gastric cancer surgery—open and laparoscopic approaches

“…It was carried out successfully as an alternative treatment for gastric ulcers in an attempt to prevent postoperative dumping syndrome and bile juice reflux [1][2][3][4]. Conventional distal gastrectomy promotes gastric remnant gastritis and eventually induces gastric remnant cancer.…”

“…This suggests the need for an optimal approach for limited surgery for early gastric cancer, and PPG is one such approach. Usually, PPG procedures do not include suprapyloric lymph node dissection to preserve the pyloric branch of the vagal nerve and the right gastric artery [1][2][3]. We have recently reported the feasibility, safety, and better quality of postoperative life of using PPG for gastric cancer treatment, even with lymphadenectomy including combined suprapyloric lymph node dissection and right gastric artery division [4].…”
