In the current era of computed tomography, idiopathic or asymptomatic intussusception is being seen more commonly; however, the majority of adult intussusceptions still have pathologic lead points. From our experience, all patients with palpable mass, obstructive symptoms or obstruction, gastrointestinal bleeding, or a lead point on computed tomography should undergo operative exploration.

Extra-ampullary and periampullary duodenal adenocarcinomas have similar survival after resection. For distal duodenal tumors, survival is improved by curative resection without being compromised by limited resection. The number of lymph nodes sampled was significantly less with segmental resection than pancreatoduodenectomy.

With long-term follow-up, extent of surgical resection did not affect DFS for patients with borderline and malignant phyllodes tumors. Tumor features, most notably stromal overgrowth, were predictive of recurrence and survival, suggesting these high-risk patients may benefit from additional therapeutic strategies.

Although 72 % of patients were rendered structurally disease free after reoperation, nearly 40 % suffered additional relapse. Improved surgical technique or preoperative localization might positively affect 15-20 %; at least 20 % reflect the biologic aggressiveness of the disease.

BACKGROUND The purpose of this study was to describe a single institution’s experience with adult intussusception and determine how this was influenced by evolving computed tomography (CT) technology. METHODS Adults treated between 1978 and 2013 for intussusception were reviewed. CT utilization and utilization of multislice technology over time were determined. Sensitivity of CT was calculated. RESULTS A total of 318 patients were identified. CT utilization was 72% and it increased over time. The number of channels ranged from 1 to 128. CT sensitivity was greater than 85% for single and multislice scanners. A lead point was identified in 69% of patients and a malignancy in 40%. Surgical exploration was required in 60% of patients and 40% were managed nonoperatively. CONCLUSIONS The diagnosis of intussusception in adults is increasing over time, particularly idiopathic intussusception. This is associated with increased utilization of highly sensitive CT technology, which facilitates the safe nonoperative management in many patients.

There is no significant difference between endoscopic and local operative resections of benign adenomas of ampulla of Vater; recurrences are more common when two or more endoscopic resections are required for complete tumor removal. Appropriate adenomas for endoscopic resection included tumors <3.6 cm that do not extend far enough intraductally (on EUS) to preclude an endoscopic snare ampullectomy.

When considering prophylactic repair during TEP explorations, a yearly risk of 1.2% of developing a contralateral hernia after negative exploration needs to be balanced against the low but potential risk of groin pain following prophylactic repair.
