Poor outcome and quality of life in female patients undergoing secondary surgery for recurrent peptic ulcer disease.

Secondary peptic ulcer surgery is uncommon given the success of a wide variety of medical therapies, plus the good outcome expected after primary peptic ulcer surgery. Early reports of secondary peptic ulcer surgery in the 1950s and 1960s suggested good long-term outcome in most patients; however, recent data suggest that patients operated in the Helicobacter pylori era have a worse outcome. We have attempted to quantify the poor outcome in these patients and measure the effect of sex, a previously unrecognized risk factor for poor outcome after peptic ulcer surgery. We reviewed the outcomes of 35 patients who underwent secondary peptic ulcer surgery for symptoms of persistent or recurrent peptic ulcer symptoms or complications of the condition. These patients were compared to a "control" group of patients to determine long-term quality of life as measured by the SF-36 and Visick scores (average follow-up 60 months). Visick and SF-36 scores were obtained through telephone interviews. The two groups of patients were age matched to eliminate age as a variable in the SF-36 results. There were more females than males in the secondary peptic ulcer surgery group (4.5/1 female-to-male ratio). Although perioperative mortality was zero for both groups, patients undergoing secondary peptic ulcer surgery had a high number of complications (57% of patients had complications). Patients undergoing secondary peptic ulcer surgery scored lower in seven of the eight subclasses of the SF-36 questionnaire compared to their age-matched cohorts. In contrast, average Visick scores showed slight improvement for three out of four symptoms reported. Immediate postoperative complications were not related to long-term quality of life issues. Secondary peptic ulcer surgery is more prevalent in females than in males. Although secondary peptic ulcer surgery is partially effective in alleviating symptoms, quality of life is poor.

Surgical management of pancreaticocutaneous fistula.

Although enteric drainage of the fistula tract is a widely accepted treatment for pancreaticocutaneous fistula, few data have been published on the outcome of this procedure. We conducted a retrospective chart review of 30 patients with pancreaticocutaneous fistula who underwent surgical management at a single institution over a 13-year period. The operative morbidity rate was 30%. Overall the incidence of recurrent ductal leaks requiring further intervention was 23%. Six of seven patients who had a recurrence had an ongoing inflammatory pathology, and three of seven had pancreas divisum. Recurrence was most likely when cystenterostomy was used. Enteric drainage of pancreaticocutaneous fistulas is not always curative. Fistulojejunostomy gives a better outcome than cystenterostomy. Recurrence may be expected in patients with continuing inflammatory ductal pathology.

Sporadic gastric carcinoid tumor laparoscopically resected: a case report.

Sporadic gastric carcinoid tumors are relatively infrequent malignancies of the stomach. Tumors measuring less than 1 cm can sometimes be safely removed endoscopically; however, larger neoplasias require surgical ablation. The present case report represents a gastric carcinoid tumor laparoscopically resected in a patient with a history of hematemesis. The tumor was first marked endoscopically with India ink, which facilitated subsequent localization of the area to be resected. Laparoscopic resection of the mass was without complication, and the pathology study confirmed the preoperative diagnosis and negativity of the margins. In patients who present with masses that are not amended for endoscopic resection, sporadic gastric carcinoid tumors can be resected laparoscopically.
