Duodenal Ulcer : goals of operative therapy Promotion of ulcer healing Treatment of specific complications Reduction of the possibility of recurrence Minimization of postoperative side effects

Duodenal Ulcer : operative procedures Truncal vagotomy and drainage Truncal vagotomy and antrectomy Parietal cell vagotomy Alternative methods

Gastric effects of truncal vagotomy Decreased acid secretion Increased serum gastrin Gastrin cell hyperplasia Accelerated liquid emptying Altered emptying of solid

Nongastric effects of truncal vagotomy Decreased pancreatic exocrine secretion Decreased postprandial bile flow Increased gallbladder volume Diminished release of vagally mediated peptide hormones

Duodenal Ulcer : operative procedures Truncal vagotomy and drainage Truncal vagotomy and antrectomy Parietal cell vagotomy Alternative methods

Duodenal Ulcer : choice of operation Location of ulcer Indication for operation Chronicity of the ulcer diathesis Age and sex, nutritional status of the patient Presence of concomitant illness Stability of the patient during the perioperative period Experience and personal preference of the surgeon

Duodenal Ulcer : indications for operation Intractability Perforation Obstruction Hemorrhage

Duodenal Ulcer : indications for operation Intractability Perforation Obstruction Hemorrhage

Intractability ; criteria Initial healing is delayed, so that ulceration persists at 3 months despite active drug therapy Ulcers recur within 1 year of initial healing despite maintenance therapy The ulcer disease is characterized by cycles of prolonged activity with brief or absent remissions

Operative procedures : intractability First choice; parietal cell vagotomy Alternatives ; truncal vagotomy and antrectomy laparoscopic vagotmy

Duodenal Ulcer : indications for operation Intractability Perforation Obstruction Hemorrhage

Clinical features ; perforated duodenal ulcer Symptoms ; sudden onset of severe epigastric pain spreading throughout the abdomen, variable degree of shock Signs ; abdominal tenderness, rigidity Plain X-ray ; peritoneal free air

Differential diagnosis ; perforated duodenal ulcer Acute cholecystitis Acute pancreatitis Strangulation obstruction Acute appendicitis Perforation of other G-I tract Mesenteric thrombosis

Operative procedures : perforation Simple closure Definitive surgery parietal cell vagotomy and omental patch truncal vagotomy and pyloroplasty truncal vagotomy and antrectomy

Indications for definitive operation No preoperative shock No life-threatening medical illness Perforation has been present for less than 48 hours

Duodenal Ulcer : indications for operation Intractability Perforation Obstruction Hemorrhage

Causes of obstruction in duodenal ulcer Inflammation and edema Fibrosis

Operative procedures : obstruction Truncal vagotomy and antrectomy Truncal vagotomy and gastrojejunostomy

Duodenal Ulcer : indications for operation Intractability Perforation Obstruction Hemorrhage

Indications for operative intervention ; duodenal ulcer bleeding Massive hemorrhage leading to shock Prolonged blood loss requiring continuing transfusion Recurrent bleeding during medical therapy or after endoscopic therapy Recurrent bleeding requiring hospitalization

Operative procedures : hemorrhage Truncal vagotomy and pyloroplasty with suture ligation of bleeding vessel Truncal vagotomy and antrectomy including ulcer or suture ligation of bleeding vessel

Timing of operation : hemorrhage Primary emergency Secondary emergency Early elective surgery

Gastric Ulcer : goals of elective operation Primary goals ; to excise the ulcer to reduce acid/pepsin output Secondary goals ; to minimize bile reflux and gastric stasis

Stomach resections: Billroth I (BI) – gastro-duodenoanastomosis end-to-end Billroth II (BII) – gastro-jejunoanastomosis end-to-side with blind closure of duodenum Proximal selective vagotomy – denervation of parietal gastric cells

Gastric ulcer : standard operations type I ; Distal gastrectomy and B-I anastomosis type II, III ; Distal gastrectomy with vagotomy type IV ; TV and drainage and biopsy/excision of ulcer Proximal gastrectomy

Gastric Ulcer : indications for elective operation Failure to heal on optimal medical therapy Suspicion of malignancy Distal gastric obstruction Giant gastric ulcer

Gastric Ulcer : emergency operation Bleeding gastric ulcer Perforated gastric ulcer

Bleeding gastric ulcer : operative procedures Gastric resection including ulcer simple oversewing excision of ulcer with TV and drainage without TV and drainage

Gastric Ulcer : emergency operation Bleeding gastric ulcer Perforated gastric ulcer

Perforated gastric ulcer : operative procedures Gastric resection Biopsy and simple closure

New Surgical Strategy for Gastroduodenal Ulcer : Laparoscopic approach Truncal vagotomy Thoracoscopic truncal vagotomy Parietal cell vagotomy

Stress Ulcer Multiple superficial mucosal erosions after major physical trauma, shock, sepsis, hemorrhage, respiratory failure, or severe burns.
