ABSTRACT To describe our series of distal pancreatectomies with preservation of the spleen utilizing the Warshaw operation with a focus on possible long-term complications due to the development of gastric varices.
The Warshaw operation was first described in 1988. The splenic vessels are resected and the spleen survives via the short gastric and left gastroepiploic vessels.
Retrospective review of 721 patients who underwent a distal pancreatectomy between February 1986 and February 2009.
The spleen was preserved via the Warshaw operation in 158 patients (22%). Median age was 55 years (range 10-85) and 72% were females. Pathologies included: 35 mucinous cystic neoplasms (adenoma 28, borderline 7), 22 intraductal papillary mucinous neoplasms (adenoma 9, borderline 9, cancer 4), 23 serous cystadenomas, 13 other pancreatic cysts, 27 pancreatic endocrine tumors, 16 chronic pancreatitis, 9 ductal adenocarcinomas, and 13 other pathologies. Only 3 (1.9%) patients required a reoperation because of splenic infarction at 3 to 100 days postoperatively because of abdominal pain and/or fever. Median follow-up was 2.7 years (mean 4.5 years, range 0-21 years). There was evidence of perigastric varices in 16 of 65 (25%) patients who had follow-up imaging at a median of 3.4 years, but none of the 158 patients developed gastrointestinal bleeding or hypersplenism.
Spleen preservation with the Warshaw operation has a low postoperative failure rate of 1.9%. Radiologic evidence of asymptomatic perigastric varices was identified in 25% of patients. There were no clinical consequences of perigastric varices in any patient during a follow-up period of up to 21 years.

    ABSTRACT: Splenic preservation is currently recommended during minimally invasive surgery for benign tumors of the distal pancreas. The aim of this study was to evaluate the outcomes of patients undergoing laparoscopic spleen-preserving distal pancreatectomy, with particular attention paid to the technique used for spleen preservation (splenic vessel ligation vs preservation). A review of consecutive patients who underwent laparoscopic distal pancreatectomy with the intention of splenic preservation was conducted. Patient demographics, operative data, and outcomes were collected and analyzed. Fifty-five consecutive patients underwent laparoscopic distal pancreatectomy with the intention of splenic preservation; 5 required splenectomy (9 %). Of the remaining 50 patients, 31 (62 %) had splenic vessel ligation, and 19 (38 %) had vessel preservation. Patient demographics and tumor size were similar. The vessel ligation group had significantly more pancreas removed (95 vs 52 mm, P < 0.001) and longer operative times (256 vs 201 min, P = 0.008). Postoperative outcomes, complication rates, and splenic viability were similar between groups. Laparoscopic spleen-preserving distal pancreatectomy is a safe operation with a high rate of success (91 %). Vessel ligation was the chosen technical strategy for lesions that required resection of a greater length of pancreas. We found no advantage to either technique with respect to outcomes and splenic preservation. Operative approach should reflect technical considerations including location in the pancreas.

    ABSTRACT: This study analyzed the time trends of demographic, operative, and pathologic variables in a consecutive series of patients undergoing laparoscopic distal pancreatectomy (LDP). In addition, we assessed the parameters potentially related to the learning curve, and evaluated the long-term outcomes.

    ABSTRACT: Laparoscopic pancreatic surgery is in its infancy despite initial procedures reported two decades ago. Both laparoscopic distal pancreatectomy (LDP) and laparoscopic pancreaticoduodenectomy (LPD) can be performed competently; however when minimally invasive surgical (MIS) approaches are implemented the indication is often benign or low-grade malignant pathologies. Nonetheless, LDP and LPD afford improved perioperative outcomes, similar to those observed when MIS is utilized for other purposes. This includes decreased blood loss, shorter length of hospital stay, reduced post-operative pain, and expedited time to functional recovery. What then is its role for resection of pancreatic adenocarcinoma? The biology of this aggressive cancer and the inherent challenge of pancreatic surgery have slowed MIS progress in this field. In general, the overall quality of evidence is low with a lack of randomized control trials, a preponderance of uncontrolled series, short follow-up intervals, and small sample sizes in the studies available. Available evidence compiles heterogeneous pathologic diagnoses and is limited by case-by-case follow-up, which makes extrapolation of results difficult. Nonetheless, short-term surrogate markers of oncologic success, such as margin status and lymph node harvest, are comparable to open procedures. Unfortunately disease recurrence and long-term survival data are lacking. In this review we explore the evidence available regarding laparoscopic resection of pancreatic adenocarcinoma, a promising approach for future widespread application.
