BACKGROUND: Pylorus-preserving gastrectomy (PPG) was originally a treatment option in gastric ulcer surgery and is now being performed as a limited surgery in some early gastric cancer cases. This study was designed to evaluate the postoperative functional characteristics of PPG versus conventional distal gastrectomy with Billroth I anastomosis (BI). METHODS: Patients who underwent PPG (study group) between November 1999 and April 2003 were enrolled and BI patients (control group) were matched f

Importance: Patients undergoing proximal gastrectomy (PG) with double-tract reconstruction (DTR) have been reported to have an incidence of reflux esophagitis that is as low as that observed after total gastrectomy (TG). It is unclear whether PG has an advantage over TG for the treatment of patients with upper early gastric cancer (GC). Objective: To evaluate the effect of laparoscopic PG with DTR (LPG-DTR) vs laparoscopic TG (LTG) on levels of hemoglobin and vitamin B12 supplementation required

This study showed that pure SDG is both safe and feasible for early gastric cancer, with similar operation time and better short-term outcomes than TLDG in terms of postoperative pain, estimated blood loss, inflammatory reaction, and cosmetic result.

MIS can be applied to submucosal gastric cancer that is less than 2 cm in size and 500 microm in depth.

ClinicalTrials.gov Identifier: NCT02490111.

The use of single-port laparoscopic surgery for treating various diseases has increased rapidly. This approach can offer better cosmetic results and less incisional pain. We report the cases of single-port laparoscopic distal gastrectomy with D1+β lymph node dissection for 2 patients with gastric cancers.
