Billroth I reconstruction
Billroth I reconstruction is a gastroduodenostomy joining the duodenum to the gastric remnant after distal gastrectomy, preserving duodenal food passage; first performed in 1881, it remains a mainstay reconstruction in Japan.
Billroth II reconstruction
Billroth II reconstruction is a surgical technique after distal gastrectomy in which the duodenal stump is closed and the stomach remnant is joined to the jejunum.
D2 lymphadenectomy
D2 lymphadenectomy is the surgical removal of the stomach's regional lymph nodes to a defined second echelon during gastrectomy for gastric cancer, standard in Japanese guidelines and high-volume European centers.
Distal gastrectomy
Distal gastrectomy is an operation that removes the lower portion of the stomach, including the pylorus, performed mainly for gastric cancer of the middle or lower stomach.
Double tract reconstruction
Double tract reconstruction is a surgical reconstruction after proximal or total gastrectomy that routes food through two pathways, preserving duodenal transit and reducing reflux esophagitis compared with esophagogastrostomy.
Gastrectomy
Gastrectomy is the surgical removal of all or part of the stomach, most often serving as curative treatment for gastric adenocarcinoma, performed through various methods.
Gastroplasty
Gastroplasty is an operation that partitions the stomach into a small pouch, used for weight loss via Vertical Banded Gastroplasty (VBG) or to lengthen a shortened esophagus.
Parasympathectomy
Parasympathectomy is surgical removal or interruption of part of the parasympathetic nervous system, chiefly vagotomy for peptic ulcer (truncal, selective, highly selective), introduced by Dragstedt in 1943 and now largely superseded by drug therapy.
Proximal Gastric Vagotomy
Proximal gastric vagotomy (highly selective, parietal cell vagotomy): ulcer operation dividing vagal branches to the acid-secreting proximal stomach while sparing antral nerves, avoiding drainage; lower side effects but higher recurrence than truncal vagotomy.
Pyloromyotomy
Pyloromyotomy is a procedure that divides the muscle of the pylorus, the stomach's outlet, used mainly for infantile hypertrophic pyloric stenosis in infants and, as endoscopic G-POEM, for refractory gastroparesis.
Pyloroplasty
Pyloroplasty is a surgical operation that widens the pyloric valve between the stomach and duodenum, most often the Heineke-Mikulicz technique, to treat gastroparesis refractory to medication.
Subtotal gastrectomy
Subtotal gastrectomy is an operation removing the distal 70% to 80% of the stomach, typically for distal gastric cancer, leaving a remnant reconnected by Billroth or Roux-en-Y reconstruction.
Truncal vagotomy
Truncal vagotomy is an operation that cuts the vagal nerve trunks to reduce gastric acid secretion, developed in 1943 for peptic ulcers and now largely obsolete.
Vagotomy
Vagotomy is a surgical operation dividing branches of the vagus nerve to reduce gastric acid, a standard peptic ulcer treatment from the 1940s until acid-suppressing drugs displaced it.
