Ninety-two patients with severe gastro-oesophageal reflux submitted to fundoplication from 1979 to 1984 have been studied. Severity of symptoms pre- and postoperatively have been assessed using a symptom score. The mean pre-operative score was 5.39 out of 9. A standard procedure for the fundoplication was used, including a long (5 cm) wrap leaving the wrap in an intrathoracic position when it could not be brought completely into the abdomen. Vagotomy was added in 53 patients. Posterior gastropexy was used in 54 patients. There was a zero incidence of damage to the spleen and a zero mortality. The mean symptom score on follow up was 0.41 out of 9 with 90.5% patients having absent or minimal symptoms. However, only 68% remained satisfied with their overall results. The incidence of sequelae related to the procedure itself including gas bloat (19.6%), dumping (7.6%) diarrhoea (6.5%) and development of gastric ulcer (2.2%) explained this discrepancy. The addition of vagotomy did not improve the results but added its complications especially dumping and diarrhoea. There were no differences in clinical results whether the fundoplication had been left in the chest or in the abdomen but there were two hazardous complications of the intrathoracic fundoplication including a perforated gastric fundus and a gastric ulcer in the thoracic part of the stomach. Posterior gastropexy conferred no benefit to the results. Measures which might improve results include: avoidance of vagotomy, intrathoracic fundoplication and gastropexy; shortening the wrap; and the use of a 50-60 F dilator in the oesophagus during the wrap.

Acute hepatic failure is characterized by a sudden catastrophic compromise of hepatic failure that causes clinical signs such as anorexia, depression, vomiting, diarrhea, icterus, and encephalopathy. Injurious hepatotoxins, drugs, infectious agents, or metabolic disturbances can cause acute hepatic failure; however, in many cases, the inciting cause is not determined. Treatment is aimed at controlling complications such as fluid-electrolyte imbalances, hepatic encephalopathy, hypoglycemia, bleeding diathesis, gastric ulcer, sepsis, and endotoxemia, in order to provide time for liver regeneration and recovery.

Misoprostol, a synthetic prostaglandin E1 methyl ester analog with gastric antisecretory and cytoprotective properties, prevents the development of acute experimental gastric and duodenal ulcers in various animal models. This study was designed as a multicenter randomized double-blind parallel-group comparison of the effects of two dosage strengths (25 and 100 micrograms q.i.d.) of orally-administered misoprostol and placebo on the healing of endoscopically-proven benign gastric ulcer in 299 out-patients. Safety was evaluated by comparison of pre- and post-treatment physical examinations, clinical laboratory tests, gastric antral biopsies and monitoring of adverse experiences. A statistically significant difference in gastric ulcer healing rate was seen at eight weeks among the treatment groups in the Intent-to-Treat Cohort: misoprostol 100 micrograms (62.0%), misoprostol 25 micrograms (50.0%), placebo (44.7%). The proportion of subjects healed in up to eight weeks of treatment was greatest in the misoprostol 100 micrograms group in all cohorts. Ulcer pain decreased in all treatment groups in successive weeks and there were no statistical differences among any of the three treatment groups. Diarrhea was the most frequently reported adverse experience: misoprostol 100 micrograms (9.8%), misoprostol 25 micrograms (7.7%), placebo (1.9%). The diarrhea was mild and self-limiting despite continued use of misoprostol. Overall evaluation of gastric antral biopsies showed no adverse changes in the morphology of the antral mucosa. We conclude that misoprostol 100 micrograms q.i.d. for up to eight weeks is safe and effective in the treatment of benign gastric ulcer.

The number of subjects who had participated in completed clinical trials of misoprostol as of 1 May 1984 was 2272. Of this number 1549 subjects were exposed to misoprostol doses as high as 400 micrograms q.i.d. and for periods up to eight weeks. In ongoing trials subjects are receiving as much as 300 micrograms q.i.d. for up to 12 weeks, or 400 micrograms daily for up to one year. Five large controlled multicenter multicountry clinical trials have been conducted with misoprostol, including double-blind placebo-controlled comparisons of misoprostol in two duodenal ulcer studies and one gastric ulcer study, and double-blind comparisons of two doses of misoprostol and cimetidine in duodenal ulcer and gastric ulcer studies. In the placebo-controlled trials the only complaint clearly associated with misoprostol therapy in a meaningful number of patients was diarrhea, defined as any change in bowel habits whether or not this included true watery diarrhea. The incidence of diarrhea was higher with misoprostol 200 micrograms (13.1% of 107 subjects) and misoprostol 100 micrograms (9.5% of 199 subjects) than with placebo (3.8% of 314 subjects). This relatively high incidence of diarrhea is offset by the fact that only four subjects had withdrawn from studies worldwide because of diarrhea. It appears that compliance was excellent. In the cimetidine-controlled studies, diarrhea and related complaints were greater with misoprostol 200 micrograms (5.6% of 337 subjects) than with misoprostol 50 micrograms (3.0% of 328 subjects) or with cimetidine 300 micrograms q.i.d. (1.8% of 327 subjects).(ABSTRACT TRUNCATED AT 250 WORDS)

In Leeds and Copenhagen 271 patients were treated electively for duodenal ulcer by parietal cell vagotomy without drainage between 1969 and 1972 inclusive, with no operative deaths. 108 patients have been followed up 2-4 years since operation. Gastric stasis necessitating re-operation occurred in only 2 cases. Gastric ulcer developed in 2 cases, and in 3 cases recurrence of the duodenal ulcer was suspected but was unconfirmed at re-operation. Uncontrolled comparison with the results of partial gastrectomy and of vagotomy with drainage, as performed at these two centers, has shown that after parietal cell vagotomy without drainage there is a much lower incidence of dumping, diarrhea and bile vomiting, and, on overall assessment, a greater proportion of perfect or very good results.

The relative merits of proximal gastric vagotomy (PGV), truncal vagotomy with drainage (TV + D), and truncal vagotomy with antrectomy (TV + A) in the treatment of chronic duodenal ulcer were evaluated and compared in 152 patients in a prospective, randomized and controlled clinical trial. One death occurred after TV + A, resulting in an operative mortality of 2% after gastrectomy and 0.7% for the entire series. After one to six years, stomal and duodenal ulcers proven by endoscopy occurred in eight patients after PGV (16%) and in six patients after TV + D (11.8%); the difference was not statistically significant (p greater than 0.5). One additional patient developed a gastric ulcer nine months after PGV. There was so far no ulcer recurrence after TV + A. Majority (13 patients) of the recurrent ulcers were discovered within three years after surgery. Patients after PGV experienced significantly less unwanted side effects than those after either TV + D or TV + A; particularly, dumping, epigastric fullness, and diarrhea. When the functional status was graded according to a modified Visick system that excluded ulcer recurrence, significantly more PGV patients were placed in the near-perfect grade (82.1%) than TV + A patients (58%). Patients after TV + D fared better than patients after TV + A; but the differences were not significant. However, when ulcer recurrence was included in the functional assessment, the advantage of PGV was lost.

The results of a 5-year follow-up of 289 consecutive, peptic ulcer patients treated by antrectomy and gastroduodenostomy, with or without vagotomy, are presented. Patients with a preoperative gastric acid secretory capacity (PAO) below 40 mmol/h were treated by antrectomy alone, while subjects with a higher PAO had a vagotomy in addition. The antrectomy was defined by lithmus indication of the corpus-antrum border and by histologic verification, including gastrin cell counting. The over all incidence of gastroscopically verified recurrent ulceration was 8.5%. In patients with ulcer location in the bulb or the pyloric/prepyloric region (juxtapyloric ulcer) and treated by antrectomy alone, the recurrence rate was 18% (n = 102), and in gastric ulcer patients it was 4% (n = 47). Altogether 14 patients with recurrent ulcer were subsequently reoperated on by vagotomy showing no further recurrence. Antrectomy combined with vagotomy was primarily performed almost exclusively in patients with juxtapyloric ulceration, in whom the recurrence rate was 2% (n = 106). According to a postoperative insulin test, the patients with recurrence after antrectomy and vagotomy were incompletely vagotomized. In patients who remained free of symptoms or signs of recurrent disease, the median reduction in gastric acid secretory capacity was about 60% after antrectomy alone and 80% after antrectomy and vagotomy. In juxtapyloric ulcer patients with recurrence after antrectomy alone there was a small median reduction in PAO one month after operation (26%) and then an increase close to the preoperative level (6% reduction). In patients with a postoperative reduction in PAO of less than 35%, there was a high probability of recurrent ulcer, about 70%. In spite of selection of patients with a comparatively low preoperative PAO (less than 40 mmol/h) for antrectomy alone, the recurrence rate was 18% in patients with juxtapyloric ulcer location. In this selected group of patients the preoperative PAO was not higher in patients with ulcer recurrence than in patients who were asymptomatic after the operation. Selecting patients with juxtapyloric ulcer for antrectomy, with or without vagotomy, on the basis of gastric acid secretory capacity therefore seems unjustified. When vagotomy was added to antrectomy and gastroduodenostomy it seemed to increase the risk of developing serious (Visick 3u and 4) postgastrectomy syndromes; 12% after antrectomy and vagotomy versus 3% after antrectomy alone. Vagotomy appeared to be associated with an increased risk of bile reflux gastritis, gastric mycosis, and milk intolerance. Dumping and diarrhoea after vagotomy often coincided with milk intolerance. Antrectomy, with or without vagotomy, did not markedly impair recorded nutritional parameters.(ABSTRACT TRUNCATED AT 400 WORDS)

In the surgical treatment of gastric ulcer (G,U,), the same techniques have been employed as have been used in duodenal ulcer (D.U.). This correspondence also holds true with superselective vagotomy and proximal gastric vagotomy (P.G.V.). The technique was primarily indicated in the treatment of D.U. and had very exciting preliminary results, above all owing to its reduced morbidity both immediately and late after surgery, and to its almost null mortality. With a view to analyzing the results of the use of P.G.V. in the treatment of gastric ulcer, thirteen patients were operated upon who were bearers of G.U. not associated with D.U. nor prepyloric ulcer. There were no operating accidents or immediate post-operative complications, nor was there any mortality. In the post-operative period following lasting an average of 17.7 months, we observed the clinical manifestation of the ulcer and symptoms accompaning the operation in addition to performing endoscopy on all of the patients. Eight patients were absolutely asymptomatic after surgery; one had slight dysphagia that diminished about 3 months after P.G.V. Three patients had recurrence of the symptoms of ulcer and one complained of intense epigastric fullness, vomting, weight loss, and a crisis of diarrhea. Radiologic and endoscopic examinations showed that this last patient had hypotonia and marked gastric stasis that were corrected surgically by means of antrectomy and the reconstitution of GI tract by the BI technique, with good results. In three patients endoscopy showed postoperative recurrence of the G.U., one of whom is assymptomatic with the clinical treatment; the other two were submitted to antrectomy with BI anastomosis in one and a 2/3 gastrectomy with BI reconstruction in the other. The cure of the lesion in 23% of the cases in the post-operative follow-up lasting an average of 17.7 months permits us henceforward to contra-indicate the P.G.V. used per se for the treatment of G.U.

Gastroduodenostomy (Billroth I) is our reconstruction of choice following gastric resection for gastroduodenal ulcer. Dissatisfaction with a Billroth II anastomosis has led us in recent years to employ a Roux-en-Y diversion in selected cases, particularly those in which the pathologic state of the pyloroduodenal canal would render a Billroth I anastomosis unsafe. During the past 7 years, truncal vagotomy-antrectomy and Roux-en-Y (VARY) has been carried out in 50 selected patients: duodenal ulcer (DU) 13 patients, gastric ulcer (GU) 11 patients, and stomal ulcer (SU) 26 patients. Fourteen patients (28%) developed postoperative complications, of which nine (18%) were of major degree and five (10%) of a lesser degree. No hospital death occurred among the 50 patients. Five patients (10%) developed postoperative delayed gastric emptying and two of the five required revision of the Roux. Forty-five patients had no clinical problems with delayed emptying. Overall results showed a Visick grading of I in 72%, Visick II in 24%, and Visick III in 4%. Further analysis revealed that of the 13 patients with DU who had VARY, 62% were Visick I, 30% Visick II, and 8% Visick III. The 11 GU patients with VARY were graded Visick I 73% and Visick II 27%. Of 26 patients with SU who underwent VARY, 77% were Visick I, 19% Visick II, and 4% Visick III. Mild to moderate dumping took place in 8% of the 50 patients, mild diarrhea 10%, weight loss 10%, and no patient experienced alkaline reflux gastritis. Long-range postoperative gastric emptying studies among nine patients using a radionuclide revealed varying patterns of emptying. Overall clinical results have been satisfactory and we are continuing to use VARY in selected cases, particularly those in which a Billroth I reconstruction appears contraindicated.

In a prospective randomised multicenter study in 41 patients with chronic gastric ulcer type I according to Johnston we compared selective proximal vagotomy (SPV) plus ulcerectomy (21 patients) with a standardised Billroth I gastrectomy (20 patients). The follow-up period was at least 2 years. Preoperative characteristics of both groups did not differ. Intraoperatively, in 5 patients of the SPV group technical problems during dissection of the lesser curvature occurred. The main postoperative complaints were pain and epigastric fullness after SPV and bile vomiting, early dumping or diarrhea after Billroth I gastrectomy. 3 of 21 patients after SPV developed recurrent ulceration, whereas after BI resection no recurrence was observed. This study indicates a higher recurrence rate in gastric ulcer patients after SPV compared to Billroth I gastrectomy.
