Proximal Gastrectomy Is a Viable Alternative to Total Gastrectomy in Early Stage Proximal Gastric Cancer.

Abstract

Background: Total gastrectomy with Roux-en-Y esophagojejunostomy is a life-extending procedure for patients with nonmetastatic proximal gastric and gastroesophageal junction adenocarcinoma, yet it can be a life-altering procedure with negative impact on quality of life.¹ Perioperative recovery often involves the need for supplemental nutrition (either enteral or parenteral). Furthermore, long-term effects of early satiety, dysphagia, sustained weight loss, and difficulty in maintaining a healthy weight, dumping syndrome, and intestinal overgrowth are not unusual. Although the alternative of untreated cancer is clearly unacceptable, these lifestyle consequences are not benign.

Methods: A retrospective review of patients who had undergone laparoscopic total and proximal gastrectomy for gastric adenocarcinoma was conducted. Patient demographic data, pathologic parameters, and short-term and long-term clinical data were compared between total gastrectomy and proximal gastrectomy cohorts.

Results: Seventeen patients were included in the study: 13 had undergone laparoscopic total gastrectomy (LTG) and 4 had undergone laparoscopic proximal gastrectomy (LPG). Patients who had LPG, given the nature of the procedure, were confined to early stage (up to T2) tumors in the gastric cardia or GE junction. Patients who had LTG tended to be larger, later stage tumors (but not exclusively). The mean operative time was greater for LTG than for LPG (247 ± 54 versus 181 ± 49 min, respectively, P = .036). Length of hospital stay (9.0 ± 3.2 versus 5.0 ± 0.8 days, P < .001) and readmission for postoperative complication (38.5 versus 0%, P = .009) were also higher in the LTG group. There was no significant difference in terms of mean estimated blood loss or blood transfusion rates, overall complications, or anastomotic stricture requiring endoscopic dilation between the patients who underwent LTG and those who underwent LPG.

Conclusion: In early stage tumors (T1b or T2), proximal gastrectomy (PG) should be considered to mitigate diminished quality of life. PG with esophagogastrostomy, which can easily be performed minimally invasively, can be more tolerable for the patient, with no anatomic basis for dumping syndrome or small intestinal bacterial overgrowth (SIBO), and a greater reservoir for more normal meal habits when compared to total gastrectomy (TG) with Roux-en-Y reconstruction.
