A multicenter analysis of distal pancreatectomy for adenocarcinoma: is laparoscopic resection appropriate?
ABSTRACT As compared with open distal pancreatectomy (ODP), laparoscopic distal pancreatectomy (LDP) affords improved perioperative outcomes. The role of LDP for patients with pancreatic ductal adenocarcinoma (PDAC) is not defined.
Records from patients undergoing distal pancreatectomy (DP) for PDAC from 2000 to 2008 from 9 academic medical centers were reviewed. Short-term (node harvest and margin status) and long-term (survival) cancer outcomes were assessed. A 3:1 matched analysis was performed for ODP and LDP cases using age, American Society of Anesthesiologists (ASA) class, and tumor size.
There were 212 patients who underwent DP for PDAC; 23 (11%) of these were approached laparoscopically. For all 212 patients, 56 (26%) had positive margins. The mean number of nodes (+/- SD) examined was 12.6 +/-8.4 and 114 patients (54%) had at least 1 positive node. Median overall survival was 16 months. In the matched analysis there were no significant differences in positive margin rates, number of nodes examined, number of patients with at least 1 positive node, or overall survival. Logistic regression for all 212 patients demonstrated that advanced age, larger tumors, positive margins, and node positive disease were independently associated with worse survival; however, method of resection (ODP vs. LDP) was not. Hospital stay was 2 days shorter in the matched comparison, which approached significance (LDP, 7.4 days vs. ODP, 9.4 days, p = 0.06).
LDP provides similar short- and long-term oncologic outcomes as compared with OD, with potentially shorter hospital stay. These results suggest that LDP is an acceptable approach for resection of PDAC of the left pancreas in selected patients.

ABSTRACT: Laparoscopic distal pancreatectomy with splenectomy is regarded as a safe and effective treatment for benign and borderline malignant pancreatic lesions [1, 2]. However, its application for left-sided pancreatic cancer is still debatable [3, 4]. No general consensus, no standardized technique, and no surgical indication exist in applying the laparoscopic approach to left-sided pancreatic cancer. According to our institutional experiences of treating left-sided pancreatic cancer, bloodless and margin-negative resection was found to be important. Bloodless and margin-negative laparoscopic distal pancreatosplenectomy would be technically possible in suspicious pancreatic cancers with these tentative conditions: (1) pancreas-confined suspicious pancreatic cancer on preoperative image study (cT2), (2) intact fascia layer between the pancreas and left adrenal gland/left kidney, and (3) tumor more than 1 cm from the celiac axis. A 59-year-old female patient was found to have suspicious left-sided pancreatic cancer. Therefore, we performed laparoscopic anterior radical antegrade modular pancreatosplenectomy (RAMPS) [5, 6] with a curative intent based on selection criteria. The margin-negative (resectional and tangential) curative resection could be obtained by applying laparoscopic anterior RAMPS in well-selected left-sided pancreatic cancer. The operation time was 180 min and estimated blood loss was 100 ml. The diagnosis from pathology was that the tumor was ductal adenocarcinoma of the pancreas (pT3) with lymph node metastasis (pN1, 2 of 23 lymph nodes). The patient went home on the 7th postoperative day. Adjuvant chemotherapy began within 2 weeks after surgery. From June 2007 to August 2010, nine patients underwent minimally invasive (5 laparoscopic and 4 robot-assisted) anterior RAMPS based on the selection criteria. The perioperative outcomes and short-term oncologic results are summarized. Laparoscopic modified anterior RAMPS is thought to be technically feasible for curative resection in well-selected pancreatic cancer. The oncologic feasibility of this technique needs to be investigated based on long-term follow-up. More careful study is necessary.Surgical Endoscopy 02/2011; 25(7):2360-1. · 4.01 Impact Factor
