Abstract. From 1970 to 1992 a total of 63 patients underwent operation for ampullary tumor: 40 pancreatoduodenectomies (PDs), 3 total PDs, 8 ampullectomies, and 12 bypass or exploratory laparotomies. The resectability rate was 68%. There were 9 benign tumors, 1 anaplastic tumor, and 53 adenocarcinomas. According to Martin’s classification, there were 7 stage I, 11 stage II, 14 stage III, and 21 stage IV tumors. All patients with stage I, II, and III tumors underwent resection. Patients with stage IV tumors had either resection (n = 11) or bypass (n = 10). The mean duration of hospital stay was 20.6 days. Operative mortality was 12.7% for the whole series and 7.5% after PD (2.5% for the last 10 years). Overall survival was 40% at 5 years (85% for stage I, 65% for stage II, 44% for stage III, and 8% for stage IV). Survival was better for stages I, II, and III after PD than after ampullectomy. For stage IV patients survival was 70% after PD versus 20% after bypass at 1 year and 25% versus 0% after 2 years. In our opinion, PD should be proposed even for benign lesions because two of our patients had to undergo repeat operation (PD) 4 and 22 years later, respectively, for stage IV disease. PD is our choice for all tumors of the ampulla.

Abstract Esophageal perforation is a life-threatening situation and represents a major therapeutic challenge. Results have improved in recent years particularly as a result of progress in antibiotic therapy and the use of total parenteral nutrition. Surgical management retains a predominant role, involving early primary closure and thoracic drainage. We have made an addition to the surgical management by applying an absorbable mesh and fibrin glue to the repaired site. Seven patients (ages 38–79 years) were treated as described. The mean interval from leak to surgery was 28 hours. Six patients had an uneventful postoperative course with a mean hospital stay of 34 days (range 26–45 days). In one case the technique failed and the patient required an exclusion-diversion procedure. All 7 patients recovered without mortality. We believe that this technique provides a real improvement for this precarious esophageal repair.
