The understanding of peptic ulcer disease (PUD) etiology, and improvements in treatment during the last two decades, has dramatically decreased the once so frequently performed procedures for PUD and its complications. Benign gastric outlet obstruction may, however, still require operative intervention when non-operative treatment fails. Today, surgeons in training, and even practicing surgeons, may have limited operative experience with procedures required to alleviate an obstructed pylorus. Our aim of this paper is to review the techniques (the Heineke-Mikulicz and Finney pyloroplasties, and modifications) and indications for pyloroplasty in the modern surgical era.

Abstract A policy of supportive treatment is frequently adopted for patients with metastatic disease to the adrenal glands. This study reports an experience with adrenalectomy for adrenal metastasis. Between 1983 and 1993, adrenalectomy was performed in 52 patients for metastasis to the adrenal glands. Survival was calculated by the Kaplan- Meier method and compared with the log rank test. Primary tumour sites included kidney (n = 15), lung (n = 11), colon (n = 7), unknown (n = 5), stomach (n = 3), melanoma (n = 3) and other (n = 8). Adenocarcinoma (69 per cent) was the most common histological cell type. Thirty-two patients were asymptomatic on initial evaluation. Symptomatic adrenal pain relief was achieved in 11 of 13 patients. Overall survival rates were 73 per cent at 1 year and 40 per cent at 2 years. Patients with potentially curative resection had better survival than those who had a palliative procedure. Patients with adrenal metastases due to adenocarcinoma had improved survival compared with that in those with other histological cell types. Although long-term survival is generally poor, highly selected patients with adrenal metastasis (symptomatic disease or adenocarcinoma) may benefit from surgical resection.

AbstractIslet cell carcinoma (ICC) of the pancreas is a rare, indolent malignancy associated with higher resectability rate and better survival than ductal carcinoma. This retrospective study presents results of surgical treatment from a single institution. From 1985 through 1993 a total of 64 patients (36 men, 28 women) were surgically treated for ICC. Ages ranged from 22 to 80 years (median 55 years) with a median postoperative follow‐up of 39 months (range 10–97 months). Of the 64 patients, 30 (47%) had functioning and 34 (53%) nonfunctioning tumors. Gastrinoma (n= 11) followed by glucagonoma (n= 6) and insulinoma (n= 4) were the most common functioning tumors. In the patients undergoing a laboratory study, 67% of the nonfunctioning tumors had elevated peptide hormone levels. Potentially curative resections were performed in 17 patients (26%), palliative procedures in 35 (55%), and exploratory laparotomy alone in 12 (19%). One patient (2%) died within 30 days after operation. Symptomatic improvement was achieved in 96% of patients with a mean duration of 22 months. Three‐ and five‐year survivals were 66% and 49%, respectively. In patients with curative resection, the disease‐free survival at 3 years was 53% (95% CI: 32–86%). The presence of diffuse hepatic metastases was a predictor of poor survival at 3 years (74% versus 58%;p= 0.05); there was no statistically significant difference in survival between functioning and nonfunctioning groups (p> 0.1). Although curative resection for ICC is rare, meaningful palliation can be achieved in most patients with rare mortality and acceptable morbidity.

AbstractEighty‐two children and adolescents (18 males, 64 females; median age 14 years) surgically treated for Graves’ disease at a single institution between 1979 and 1993 were retrospectively reviewed. Most of the patients (74%) coming to thyroidectomy had been treated medically for a period ranging from 2 to 80 (median 15) months. Bilateral subtotal thyroid resection was the most frequently performed procedure (86%). Postoperatively, no permanent recurrent laryngeal nerve palsy or permanent hypocalcemia occurred. Operative mortality was zero. With a median follow‐up of 8.3 years, recurrent hyperthyroidism occurred in five patients (6%), one of whom required reoperation. Most children and adolescents with Graves’ disease can be rendered euthyroid by nonsurgical treatment options. However, prolonged and ineffective medical treatment should be avoided in these patients who are in the formative years of their lives. Surgical treatment, when indicated and employed, offers young patients with Graves’ disease a safe, rapid, definitive, cost‐effective treatment with a high success rate.

AbstractSurgical treatment for adrenal disease may be withheld from elderly patients because of concern about prohibitive operative morbidity and mortality. To obtain objective data in our practice, we analyzed the results of adrenalectomy for patients aged 65 years and older. From 1984 to 1993 there were 85 patients (41 men, 44 women) with ages ranging from 65 to 84 years (median 69 years) who underwent adrenalectomy for Cushing syndrome (n= 19), pheochromocytoma (n= 16), adrenocortical carcinoma (n= 7), benign adenoma (n= 26), or primary hyperaldosteronism (n= 17) at our institution. Median follow‐up was 26 months (range 1 month to 9.1 years). A retrospective review with respect to preoperative risks and postoperative morbidity and mortality was performed utilizing the American Society of Anesthesiologists (ASA) physical status classification and the modified Goldman multifactorial cardiac risk scheme. Survival was estimated by the Kaplan‐Meier methods. Operative mortality was 7% (six patients). No patients with pheochromocytoma or primary hyperaldosteronism died during the postoperative period. Patients undergoing adrenalectomy for adrenocortical carcinoma had a significantly higher operative mortality (43%) (p= 0.006). Postoperative complications developed in 19 patients (22%), and there was a reoperation rate of 6% (5 patients). Nineteen percent of patients required postoperative intensive care admission and had a median stay of 2 days (range, 1–38 days). Median hospital stay was 7 days (range 3–47 days). Seventy‐three patients (86%) remained alive at study completion. Two‐ and five‐year survivals were 86% and 84%, respectively. Goldman class II or greater was an excellent predictor of increased morbidity (p= 0.032) and mortality (p= 0.036). With the exception of adrenocortical carcinoma, adrenal surgery for elderly patients can be performed with acceptable morbidity and mortality. The Goldman multifactorial cardiac risk scheme reliably predicts postoperative outcome in this elderly group of patients.

AbstractTo evaluate long‐term survival of patients with gastrointestinal carcinoid tumors and to assess factors that may influence prognosis, 154 patients (49% females, 51% males), median age 62 years (range 12–84 years) treated at our institution during 1972–1982 have been followed long term. Tumor location included the foregut (7%), midgut (62%), and hindgut (30%). Ninety‐five percent of the patients underwent surgical or endoscopic excision of the primary tumor, with overall operative mortality and postoperative morbidity rates of 2.6% and 11%, respectively. At follow‐up, 60 patients (39%) were alive (median follow‐up 18 years; range 1–26 years). The main causes of death included carcinoid tumor burden (32%), unrelated causes (45%), other malignancy (19%), and unknown causes (4%). Observed overall 5‐ and 10‐year survivals were 69% and 53%, respectively. Survival was not related to gender or symptoms at presentation. However, age, embryologic origin, tumor size, depth of invasion, nodal status, and stage of disease proved to be of statistical significance (log‐rank). In a multivariate Cox' model, only older age (> 62 years) [P =0.001, odds ratio (OR) = 3.4) and embryologic origin (midgut versus foregut) (P = 0.045, OR = 0.45) provided independent prognostic power when death from any cause was taken as the end‐point. This study confirms that patient's age and the site of the primary tumor have prognostic significance. Carcinoid tumors are neuroendocrine tumors with a relatively good prognosis, and long‐term survival is possible despite advanced stages of disease.
