Small bowel obstruction due to a paracolonic retroperitoneal hernia.
Hernias involving the retroperitoneum are unusual. The most common of these are the paraduodenal hernias. A retroperitoneal hernia occurring from a lateral defect in the colonic retroperitoneal attachments is presented. We believe that this case represents a newly recognized variant of retroperitoneal hernias.

Laparoscopic spleen-preserving distal pancreatectomy.
Distal pancreatectomy with spleen preservation may be the preferred procedure for certain benign tumors and cystic lesions of the pancreatic body or tail. Alternatively, laparoscopic removal including either distal pancreatectomy with splenectomy or splenic-preservation with ligation of the splenic vessels have also been described. We describe, herein, our method to perform spleen-preserving laparoscopic distal pancreatectomy that preserves the splenic vessels and hence splenic function. The described technique of spleen-preserving distal pancreatectomy has been used in two patients with favorable results. Both patients underwent laparoscopic distal pancreatectomy with splenic conservation for an oligocystic serous cystadenoma and serous cystadenoma. Operative time was 3-6 hours with total blood loss of less than 200 cc in both cases. The length of stay in the hospital was 4-8 days and both patients returned to work within 3 weeks. Laparoscopic spleen-preserving distal pancreatectomy should be considered for younger patients with select body or tail lesions that are not candidates for less extensive procedures.

Pancreaticoduodenectomy in the presence of superior mesenteric venous obstruction.
The study goal was to determine the technical feasibility and outcomes associated with pancreaticoduodenectomy for periampullary malignancies with near (>80%) or complete (100%) superior mesenteric venous (SMV) obstruction. A retrospective examination of 11 patients with high-grade or complete SMV obstruction who underwent pancreaticoduodenectomy at five academic medical centers is reviewed. Pancreaticoduodenectomy for locally advanced periampullary malignancies causing high-grade or complete SMV obstruction is technically feasible. Operative approaches and outcomes are presented. One 30-day death was observed. Median survival of the cohort is 18 months. Survivals exceeding 2 years post-resection have been observed. In a number of cases, significant palliation of pain and of biliary and duodenal obstruction were achieved. Based on this initial series, pancreaticoduodenectomy in the presence of near or total SMV obstruction is feasible, may result in an R0 resection, and may be beneficial in select patients with a periampullary malignancy. We suggest such an approach be considered particularly following completion of neoadjuvant therapy without systemic progression. Further studies and more long-term follow-up at high-volume centers are required, however, to better determine the indications and potential benefit of such an undertaking.
