Laparoscopic retrieval of an intra-abdominal air gun pellet.

A 19-year-old man presented to the emergency department following an air gun pellet injury to the abdomen. He was clinically stable and underwent laparoscopic retrieval of the pellet, which was found embedded in the small bowel mesentery. He recovered fully and was discharged after 2 days. We further discuss air gun-related injuries.

Endoscopic resection with or without mucosal ablation of high grade dysplasia and early oesophageal adenocarcinoma--long term follow up from a regional UK centre.

BACKGROUND: Endoscopic resection (ER) is emerging as a curative technique in patients with high-grade dysplasia (HGD), intramucosal cancer (IMC), and early submucosal cancer (T1sm1) within Barrett's oesophagus. METHODS: This consecutive case series of 72 patients with HGD or IMC reports outcomes of ER, with or without mucosal ablation, in a single institution after a median of 38 months follow-up between 2004 and 2011. The primary outcome was disease progression to submucosal invasion. Secondary outcomes included disease regression, the effect of ER on staging compared to biopsy and procedure-related complications. RESULTS: 72 patients (mean age 73.0 - range 52.0-93.0) were treated by ER ± ablative therapy with curative intent for HGD (88% patients) or IMC (12%). 38% had one or more severe systemic co-morbidities. A median of 4 (1-11) procedures were undertaken per patient. In addition to ER, 43% of patients were treated with argon plasma coagulation, 17% with radiofrequency ablation, and 11% with photodynamic therapy. 8 (13%) patients with HGD at baseline and 0 (0%) with IMC progressed to invasive carcinoma. The median time to progression was 26.3 and 12.6 months respectively. 51% patients experienced disease regression. Disease staging was upgraded by ER in 27% of patients. DISCUSSION: This case series reports on a minimally invasive technique in an elderly population with multiple co-morbidities, demonstrating disease regression with long-term follow-up. CONCLUSION: ER ± ablation is an effective and potentially curative option for patients with HGD or IMC. The benefit of endoscopic resection for disease staging was clearly demonstrated.
