Background: Carcinoma of the cardia of stomach or carcinoma of the esophagocardiac (EC) junction has a poor prognosis. Proximal subtotal gastrectomy is often performed for a smaller tumor. It achieves a prognosis similar to that of total gastrectomy and prevents pernicious anemia. A better functional result was expected than that total gastrectomy did from us, but the clinical observation was surprising. Most patients had symptoms of reflux esophagitis after surgery. All of these patients were reevaluated.
Methods: From November, 1990 to March, 1996, there were 27 patients who received proximal subtotal gastrectomy at this hospital. Twenty of these were involved in this study. Floppy Nissen's fundoplication was performed during operation as a anti-reflux procedure. Continuous 24-h pH monitoring, esophageal manometry, and endoscopic examination were performed for study.
Results: Most of the patients had symptoms of gastroesophageal reflux. 80% (16/20) of the patients were found to have reflux esophagitis under endoscopy. The patients had higher pH scores (mean 85.8 +/- 45.6) than normal (< 17.5), lower pressure of LES (8.03 +/- 7.01 mmHg), shorter total lengths (mean 1.60 +/- 0.56 cm) and intraabdominal lengths (mean 1.29 +/- 0.30 cm) of new lower esophageal sphincters.
Conclusions: Clearly there was failure to prevent reflux esophagitis through floppy Nissen's fundoplication. Severe gastroesophageal reflux did appear after proximal gastric resection. A gastric remnant with safe cut-margin is often too short to perform complete wrapping. Proximal subtotal gastrectomy is not recommended for early cancer of the cardia of the stomach.

Gastroesophageal reflux is a common physiologic event in infants in which gastric contents pass from the stomach into the esophagus. Gastroesophageal reflux may be asymptomatic or cause regurgitation or "spit up." This occurs daily in approximately 40% of infants.

Proximal gastrectomy (PG) has reemerged as a viable surgical option for managing proximal gastric cancer and gastroesophageal junction cancer, particularly for early-stage tumors, offering potential advantages over total gastrectomy (TG). This review examines the evolution of PG, emphasizing surgical techniques and outcomes. Although PG was initially abandoned due to postoperative complications such as reflux esophagitis, advances in reconstruction methods, such as the double-flap technique and double-tract reconstruction, have significantly improved patient quality of life and reduced complications.

Background: The selection of an appropriate gastrointestinal (GI) reconstruction procedure after proximal gastrectomy (PG) has long been a challenge. Surgeons have had a long history of exploring anti-reflux gastroesophageal anastomosis. The aim of this article is to systematically summarize the anti-reflux principles of GI reconstructive procedures through a review of the previous literature and to provide a theoretical basis for clinicians to select or innovate procedures.

Objective: The purpose of this study was to assess the 5-year impact of a per oral endoscopic myotomy (POEM) program on both clinical and financial outcomes for our hospital system and the rural community we serve.
Methods: We evaluated the clinical and financial outcomes of all patients who underwent POEM for achalasia. Patients were also contacted by phone to complete the Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL) questionnaire postoperatively.

Background And Aims: Several studies have hypothesized that sparing the oblique/sling fibers during posterior peroral endoscopic myotomy (POEM) may reduce the incidence of gastroesophageal reflux disease (GERD) and reflux esophagitis without compromising the established safety and efficacy of the procedure. This study compares perioperative, postoperative motility-related, and postoperative GERD-related outcomes between posterior oblique/sling fibers-sparing POEM (OFS-POEM) and conventional posterior POEM through a pairwise meta-analysis of comparative studies.
Methods: We conducted a systematic literature review following PRISMA guidelines to identify articles directly comparing posterior OFS-POEM with conventional posterior POEM.
