OBJECTIVETo study the long-term results of extended parietal cell vagotomy (EPCV) in the treatment of patients with duodenal ulcer and their complications.

METHODSForm 1979 to 2001, EPCV was performed in 321 patients with duodenal ulcer and their complications. Of these patients 56 had chronic duodenal ulcer, 204 perforation, 16 hemorrhage and 40 stenosis. The following items were evaluated: complications of operation, gastric secretion, gastric emptying, endoscopical and radiographical findings, nutritional status, absorption function, and Visick scale.

RESULTSPostoperative follow-up ranged from 0.5 to 22.0 years (mean 11.3 years) in 289 of the 321 patients with a follow-up rate of 90.0%. Neither operative mortality nor dumping syndrome was noted. Episodic postprandial fullness occurred in 19 patients (6.5%), acid regurgitation in 17 (5.8%) and adhesive ileus in 4 (1.4%). Ulceration recurred in 16 patients (5.5%). Duodenal ulcer was seen in 8 patients (19.5%), hemorrhage in 0 (0%), stenosis in 2 (5.3%), and perforation in 6 (3.1%). Ulcers healed rapidly after medical therapy in 10 patients. Six patients received antrectomy and gastrectomy. In 289 (91.7%) patients of Grade I and II of Visick scale, 191 (95.3%) had perforation.

CONCLUSIONSEPCV is easy to perform with a low rate of post operative complication and ulcer recurrence. It should be a treatment of choice for acute perforation, hemorrhage or stenosis due to duodenal ulcer.

OBJECTIVETo evaluate the long-term effects of retrograde liberated highly selective vagotomy (RLHSV) in the treatment of duodenal ulcer.

METHODSSeventy patients with duodenal ulcers complicated by stenosis, bleeding, or perforation were operated on by retrograde liberated highly selective vagotomy. Among these patients, 61 had perforated duodenal ulcers, 6 bleeding and 3 stenosis.

RESULTSFollowed up for 30 to 120 months in 65 patients showed a recurrence rate 7.69% and no hemorrhage occurs. According to the modified Visick grading system, 56 patients (86.2%) were of Visick I, 4 (6.1%) of Visick II, 2 (3.0%) Visick III, 3 (4.6%) Visick IV, and (92.3%) Visick I or II.

CONCLUSIONSThis modified procedure is rapid, easy and radical operation with excellent long-term results. It can be considered an effective alternative for the treatment of duodenal ulcer with complication.

Axotomy of the vagal motor neurons by cervical vagotomy induces NADPH diaphorase staining due to increased nitric oxide synthase expression in both the rat dorsal motor nucleus and nucleus ambiguous; furthermore, cerical vagotomy leads to cell death of the dorsal motor nucleus cells. Subdiaphragmatic vagotomy axotomizes the vagal motor cells further from the brainstem than cervical vagotomy, and cuts the fibers running only to the abdominal viscera. Here we report that subdiaphragmatic vagotomy is sufficient to induce NADPH diaphorase staining in the dorsal motor nucleus but does not induce staining in the nucleus ambiguus. Because the neurons of the dorsal motor nucleus do not undergo cell death after subdiaphragmatic vagotomy and are able to re-enervate the gut, the increased nitric oxide synthase expression after distal axotomy may be related more to regeneration than degeneration.

OBJECTIVETo study the long-term clinical results of 34 chronic duodenal ulcer patients treated with high selective vagotomy plus pylorus-preserved mucosal antrectomy (HSV + PPMA).

METHODSClinical follow-up results of the patients from 8 approximately 14 years were analyzed.

RESULTSThirty-tow patients (94.1%) followed-up for 8 approximately 14 years after operation achieved Visick grades I-II. No patient died. Gastric acid secretion and infection rate of Helicobacter pylori in the antral mucosa were significantly reduced after operation. No significant difference was found in bile acids, total bacterial counts in gastric juice, and the level of serum gastrin after operation. Gastric emptying was normal. No ulcer recurrence was found by barium meal and endoscopy.

CONCLUSIONSHSV + PPMA is a better operative treatment for duodenal ulcer, which not only can decrease acid secretion and ulcer recurrence rate but also can preserve the function of antrum and pylorus and prevent post-operation bile reflux and intragastric bacterial overgrowth.

OBJECTIVETo study the long-term curative effects of suture plus proximal gastric vagotomy (PGV) and suture plus triad-therapy (omeprazole, amoxycillin and flagyl taken orally) for the treatment of duodenal ulcer with acute perforation.

METHODSThree hundred and twenty-nine patients with duodenal ulcer and acute perforation were treated with 2 different methods, respectively. Method A was suture plus PGV (group A, 153 cases), and method B was suture plus triad-therapy (group B, 176 cases). Follow-up was made by means of correspondence, outpatient reexamination and cooperation with local hospitals in 5 to 8 years after operation. The contents of follow-up included symptom acquisition (such as upper abdominal pain or distention, pyrosis, belch, acid regurgitation, vomiting, diarrhea and conditions of living or working), gastroscopy and Helicobacter pylori (HP) detection. The curative effects were evaluated by the Visick scale.

RESULTSThree hundred and one patients were followed up (group A 142 and group B 159). According to the Visick scale, 97 (68.3%), 19 (13.4%), 13 (9.15%) and 13 (9.15%) patients in group A, and 31 (19.5%), 28 (17.6%), 24 (15.1%) and 76 (47.8%) in group B were classified as Visick I, II, III and IV respectively (Z = -9.818, P < 0.01). As for HP detection, there were 130 (91.5%) patients in group A and 94 (59.1%) in group B (chi(2) = 41.438, P < 0.01).

CONCLUSIONSThe long-term curative effects of suture plus PGV were superior to those of suture plus triad-therapy for duodenal ulcer with acute perforation although HP positive rate was higher in group A than in group B. HP infection is one of the etiological factors of duodenal ulcer. The increased excitability of the vagus nerve remains to play an important role in duodenal ulcer.
