Recurrent peptic ulcers

Variations reported in surgical practice for bleeding duodenal ulcers

BACKGROUND

To determine the current surgical management of bleeding duodenal ulcers in our program, faculty (FAC) and residents (RES) were surveyed.

METHODS

FAC (n = 33) and RES (n = 42) were surveyed regarding their surgery of choice between oversew (OS) or acid-reducing procedures (ARPs) in 4 scenarios. FAC who had recertified in general surgery (RECERT) were compared with young FAC who had not and RES (RES/young FAC). Two-group comparisons were performed.

RESULTS

Seventy-three percent of FAC and 62% of RES responded. RES perform more ARPs on hemodynamic (HD), unstable, elderly patients than FAC (P = .013). On the elderly patient, RES/young FAC perform more ARPs in a HD stable (P = .07) and unstable condition (P = .18). HD unstable patients would undergo OS more frequently than stable patients (P = .016).

CONCLUSIONS

In this survey, the choice of optimal surgical procedure for an acute bleeding ulcer varies among surgeons based on years of surgical experience and individual patient factors.

Long-term clinical results of highly selective vagotomy performed between 1980 and 1990

A retrospective analysis was conducted of 778 patients who underwent highly selective vagotomy between 1980 and 1990. Surgery was performed for duodenal ulcers without any complications in 485 (62.3%) patients; for duodenal ulcers with complications such as stenosis, bleeding, or perforation in 270 (34.7%); for combined duodenal and ventricular ulcers in 12 (1.5%), and for ventricular ulcers alone in 11 (1.4%). Pyloroplasty was additionally performed in the presence of complications only. The incidence of intraoperative complications proved to be as high as 1.4%, occurring in 11 patients, while postoperative complications developed in 247 patients (31.7%). Although the overall mortality was 0.6% (5 patients), the mortality rate of those patients who underwent surgery for uncomplicated ulcer disease was 0.2% only (2 patients). The patients comprised 554 men (71.2%) and 224 women (28.8%) with an average age of 41.4 +/- 0.7 years. The average duration of duodenal ulcer disease was 9.5 years, and 643 (83.2%) of the patients were able to be regularly followed up for between 3 and 13 years. Recurrence developed in 62 patients (9.6%): in the duodenum in 57 patients (91.9%), and in the stomach in 5 (8.1%). The rate of recurrence according to sex was 9.4% in men and 10.3% in women, being 42 and 20 patients, respectively. The average duration until recurrence appeared was 27.06 +/- 3.44 months. A reoperation proved necessary in 28 of these 62 patients (45.1%). The clinical results were evaluated by means of a modified Visick classification, according to which 81.8% of the patients belonged to groups 1 or 2, 7.9% to group 3, and 10.3% to group 4.

Prepyloric antrectomy, truncal vagotomy, and front pylorotomy for the treatment of duodenal ulcer

We have performed a suprapyloric antrectomy with anterior pylorotomy and truncal vagotomy in 106 patients with chronic duodenal ulcer between 1975 and 1990. Follow-up was carried out in 94 patients, during a mean time of 6 years. We have had no postoperative mortality and no long-term recurrence. The percentage of Visick I patients is similar to that after truncal vagotomy and antrectomy. We, therefore, believe that this procedure is safe and can be performed when an antrectomy is mandatory to avoid the operative morbidity and mortality of classic antrectomy.

Effects of highly selective vagotomy and additional procedures on gastric emptying in patients with obstructing duodenal ulcer

A solid gastric emptying study was conducted on 46 patients more than 1 year after highly selective vagotomy (HSV) and additional procedures for obstructing duodenal ulcer and on 21 patients after HSV alone for uncomplicated duodenal ulcer. The additional procedures included dilatation (n = 14; HSV + D group), Holle pyloroplasty (n = 14; HSV + P group), and Jaboulay gastroduodenostomy (n = 18; HSV + GD group). The test meal consisted of two eggs labeled with 99mTc sulfur colloid, two slices of white bread toast, and 300 ml of orange juice (total 322 kcal). Gastric emptying curves and emptying parameters (t1/2, half emptying time; lag phase, TLAG; emptying rate, k; and beta value) were compared with those of 17 healthy volunteers, the normal control group. The patients after HSV alone had an almost normal gastric emptying. The HSV + D group showed a significant delay from minute 45 to the end of the emptying curve, corresponding to a longer t1/2 (p = 0.02), and a slower emptying rate (p = 0.029). The HSV + P group approached a nearly normal emptying curve, corresponding to an insignificant difference in emptying parameters. The HSV + GD group had significantly faster emptying from minute 15 to the end of the emptying curve, corresponding to a faster t1/2 (p = 0.0005), a shorter lag phase (p = 0.027), and a faster emptying rate (p = 0.021). Recurrent ulcerations were noted in one patient (4.8%) of the HSV alone group, five (35.7%) of the HSV + D group, one (7.1%) of the HSV + P group, and one (5.6%) of the HSV + GD group.(ABSTRACT TRUNCATED AT 250 WORDS)

Six-year results of a prospective, randomized trial of selective proximal vagotomy with and without pyloroplasty in the treatment of duodenal, pyloric, and prepyloric ulcers

In a consecutive series of patients with uncomplicated prepyloric, pyloric, or duodenal ulcer, 39 patients were randomly allocated to selective proximal vagotomy with pyloroplasty, and 40 patients to selective proximal vagotomy alone with no operative mortality. Before surgery, all patients had undergone H2-receptor antagonist treatment. No patient was lost for follow-up. At an average follow-up of 6 years, recurrent ulcer was recorded in 15% and 20%, respectively, after selective proximal vagotomy with and without pyloroplasty. Three of 14 recurrent ulcers were asymptomatic. Epigastric pain with or without ulcer was significantly less common after selective proximal vagotomy with (13%) than without pyloroplasty (40%). Mild diarrhea or mild dumping was recorded in a few patients. The overall results were very good or good (Visick I or II) in 77% and 55% (significant difference) after vagotomy with and without pyloroplasty, respectively, and in 82% and 58%, if asymptomatic ulcers were graded as Visick I or II results. Of the 27 patients with Visick III or IV results, three patients needed no treatment (asymptomatic ulcers), and 10 patients had no symptoms during medical treatment. Two patients with vagotomy and pyloroplasty and nine with vagotomy alone were reoperated. There were no deaths, and the results were graded as Visick I or II in 10 patients and as Visick III in one patient. The authors conclude that selective proximal vagotomy with pyloroplasty is superior to vagotomy alone for the treatment of prepyloric-pyloric and duodenal ulcer. Recurrent ulcer after vagotomy has a benign course and responds well to ranitidine treatment.

Bleeding duodenal ulceration: the results of emergency treatment with highly selective vagotomy

We report the results of a prospective study of all patients undergoing highly selective vagotomy (HSV) for bleeding duodenal ulceration (BDU) at Concord Hospital between 1979 and 1989. Highly selective vagotomy was undertaken in 63 patients (58 male, 5 female) with a median age of 69 years (range: 16-89). Fifty-five patients were reviewed, 7 patients having died in the peri-operative period and one being lost to follow-up. The mean period to review was 50 months (range: 1-120). Thirty-six patients have been followed-up for more than 24 months. Thirty-day postoperative mortality was 11% (7 patients). Combined major and minor morbidity was 41%. Postoperative rebleeding occurred in four patients (6.3%), three of whom died. Ulceration had recurred in two of 55 patients (4%). Symptoms have been evaluated in 55 patients since operation and 93% have been graded as Visick I or II. We conclude that HSV is effective in the emergency treatment of BDU and has few long-term sequelae.

Twelve-year follow-up of a prospective, randomized trial of selective vagotomy with pyloroplasty and selective proximal vagotomy with and without pyloroplasty for the treatment of duodenal, pyloric, and prepyloric ulcers

Between 1973 and 1981, 161 patients with prepyloric, pyloric, or duodenal ulcers were randomly allocated to selective vagotomy with pyloroplasty, selective proximal vagotomy with pyloroplasty, or selective proximal vagotomy alone. No significant differences in clinical results were found 3 years after surgery by Emås and Fernström (Am J Surg 1985; 149: 236-42). There was one postoperative death, and one patient lost to follow-up. Of 159 patients, 52 underwent selective vagotomy with pyloroplasty, 55 selective proximal vagotomy with pyloroplasty, and 52 selective proximal vagotomy alone. Fifteen patients did not undergo endoscopy, but they had no epigastric complaints. From 1 to 16 years after surgery, recurrent ulcer was detected in 13%, 18%, and 23%, respectively, after selective vagotomy with pyloroplasty, selective proximal vagotomy with pyloroplasty, or selective proximal vagotomy without pyloroplasty. Twenty-eight percent of the patients with recurrent ulcer had no symptoms and received no treatment. Sixteen patients died within 8 years after surgery of causes unrelated to the ulcer disease. At their final examination, 14 of the 16 patients had Visick I or II (modified Visick scale) results, and the disease that caused their deaths obscured evaluation in 2 patients. The remaining 143 patients were followed up for 8 to 16 years (average: 12 years). Epigastric pain with or without ulcer was recorded more often (significant) after selective proximal vagotomy alone (40%) than after selective vagotomy with pyloroplasty (17%) or selective proximal vagotomy with pyloroplasty (14%). Bowel habits were unchanged in 96% of patients who underwent selective vagotomy with pyloroplasty or selective proximal vagotomy with pyloroplasty and 100% of patients who had selective proximal vagotomy alone. Mild dumping tended to be more common after vagotomy with pyloroplasty but was a minor nuisance in only a few patients. Very good or good results (Visick I or II) were recorded in 75% of the patients after selective vagotomy with pyloroplasty or selective proximal vagotomy with pyloroplasty or selective proximal vagotomy with pyloroplasty and in 54% after selective proximal vagotomy alone (significant difference). Seventeen patients underwent reoperation with antrectomy and gastrojejunostomy Roux-en-Y (13 patients) or gastroduodenostomy (4 patients) with no mortality. The results of the reoperations were graded as Visick I or II results in all but one patient. The final grading, including the reoperations, were Visick I or II in 85% of patients after selective vagotomy with pyloroplasty and selective proximal vagotomy with pyloroplasty and in 55% after selective proximal vagotomy alone (significant difference).(ABSTRACT TRUNCATED AT 400 WORDS)

Current surgical management of duodenal ulcers

The optimal treatment of duodenal ulcer disease today requires familiarity with a variety of operative approaches. Experience and judgment are needed to select the best procedure for the individual patient presenting with a specific ulcer complication. Improved medical therapy has relegated surgery largely to the role of emergency life-saving intervention. Nonetheless, the goal of surgery remains cure of the ulcer diathesis with avoidance of postoperative side effects. Toward this end, proximal gastric vagotomy has proved itself to be the operation of choice, not only for intractable pain, but also for perforation and perhaps for bleeding in selected good-risk patients. Its efficacy in the treatment of obstructing duodenal ulcer has not been demonstrated. Modifications of proximal gastric vagotomy, including the use of laparoscopic techniques, are currently being evaluated in patients with intractable duodenal ulcer pain.

Complications associated with ulcer recurrence following gastric surgery for ulcer disease

The present study is an attempt to assess the risks of the complications associated with recurrent ulcers in patients who have undergone gastric surgery and to determine whether these risks differ from those observed in patients receiving long term maintenance treatment with H2-receptor antagonists for ulcer disease. One hundred and thirty studies reported in the literature during the past three decades have been analysed to determine both the approximate rate of ulcer recurrence and the proportion of patients with recurrent ulcers who have presented with either haemorrhage or perforation following the various types of gastric surgery for ulcer disease. From these data, estimates of the risks of haemorrhage and of perforation during the years following gastric surgery have been calculated. Vagotomy and antrectomy is associated with a low risk of ulcer recurrence (less than 1%) and the risk of complications in later years is accordingly very small (less than 0.5%). Partial gastrectomy, although associated with low recurrence rates, has a higher risk of complications (1.3% for haemorrhage, 0.3% for perforation) because the proportion of recurrent ulcers that present with haemorrhage or perforation is high (33% and 8%, respectively). Truncal vagotomy plus drainage (TV + D) and highly selective vagotomy (HSV) are associated with recurrence rates of 9% and 12%, respectively, but ulcer recurrences following these operations are less frequently accompanied by complications then recurrences after gastric resection and, as a result, the risks of haemorrhage (1.7% for TV + D; 1.3% for HSV) are similar to the risks after gastric resection. During long term (five years or more) maintenance treatment with H2-receptor antagonists, the risks of haemorrhage and perforation are less than 2% and less than 0.5%, respectively. It appears, therefore, that the likelihood of developing haemorrhage or perforation following gastric surgery is of the same order as that during maintenance treatment with H2-receptor antagonists, at least during the first decade of follow-up.

Surgical treatment of peptic ulcer disease

Elective surgery for peptic ulcer disease has diminished significantly over the past 15 years. However, emergency surgery has not shown a decline. Some series have even reported an increase in hospitalizations and operations for hemorrhage. The appropriate surgical procedure for peptic ulcer disease must be tailored to the specific needs of the individual patient. During emergency operations for hemorrhage from duodenal ulcer, we recommend suture ligature of the bleeding vessel and vagotomy-pyloroplasty for high-risk patients, or vagotomy-antrectomy for the lower-risk patient. Bleeding gastric ulcers should be resected, if possible. For massive hemorrhage from stress ulceration requiring surgery, near-total or total gastrectomy should be performed. Perforated duodenal ulcers are best managed by closure and a definitive ulcer operation, such as vagotomy-pyloroplasty. Perforated gastric ulcers are best excised but may be simply closed if conditions do not favor resection. In these situations, biopsy should be performed. We recommend truncal vagotomy-antrectomy for patients presenting with obstruction. Vagotomy (truncal or proximal gastric) with drainage is an acceptable alternative in this situation. For patients with intractable ulcer disease or for those who are noncompliant, proximal gastric vagotomy is the preferred operation. However, other operations may need to be considered, depending on the specific situation. Recurrent ulceration needs appropriate work-up to determine the possible cause. Although patients with ulcer recurrence initially may be placed on medical treatment, about 50% will require reoperation. The most effective procedure for peptic ulcer disease is truncal vagotomy-antrectomy, which has a recurrence rate of less than 1%. The procedure with the least morbidity and the fewest undesirable side effects is proximal gastric vagotomy. Ulcer recurrence after proximal gastric vagotomy or truncal vagotomy-pyloroplasty is in the range of 10% to 15%.

Use of endoscopic Congo red test in the evaluation of ulcer recurrence risks after proximal gastric vagotomy. A new interpretive method

The endoscopic Congo red test (ECRT) was performed in 43 patients who underwent proximal gastric vagotomy (PGV) for duodenal ulcer (DU). The aim of the study was to develop a standard and reliable way to interpret the results obtained in this test. Thus, the results of ECRT were related to post-operative clinical evaluation and to pre- and post-operative basal and pentagastrin-stimulated gastric acidity. Whenever ECRT was considered positive, we called it in "large extension" if a red-to-black colour change occurred in three or more of the areas studied. Positive ECRT was observed in 39 patients (90.7%). There was a statistically significant (P less than 0.01) correlation between poor clinical results and positive ECRT in "large extension". We concluded that: (1) a positive ECRT result has no clinical or prognostic significance in DU patients after PGV; (2) ECRT, analysed according to the extension of the areas turning black, is a practical and reliable method to establish clinical results and prognosis in these patients.
