ABSTRACT

To compare preservation with the division of the splenic vessels in the surgical management of laparoscopic spleen-preserving distal pancreatectomy.
Bicentric retrospective study.
Prospectively maintained databases.
Between January 1997 and January 2011, 140 patients who underwent laparoscopic spleen-preserving distal pancreatectomy for benign or lowgrade malignant tumors in the body/tail of the pancreas were included. Patients treated with the attempted splenic vessel preservation were compared with patients treated with the attempted division of the splenic vessels (Warshaw technique).
Operative outcomes and postoperative morbidity were evaluated.
The outcomes of 55 patients in the splenic vessel preservation group were compared with those of 85 patients in the Warshaw technique group. The clinical characteristics were similar in both groups, except for tumor size, which was significantly greater in the Warshaw technique group (33.6 vs. 42.5 mm; P=.001). The mean operative time, mean blood loss, and rate of conversion to the open procedure did not differ between the 2 groups. The rate of successful spleen preservation was significantly improved following the splenic vessel preservation technique (96.4% vs. 84.7%; P=.03). Complications related to the spleen only occurred in the Warshaw technique group (0% vs. 10.5%; P=.03), requiring a splenectomy in 4 patients (4.7%). The mean length of stay was shorter in the splenic vessel preservation group (8.2 vs. 10.5 days; P=.01).
The short-term benefits associated with the preservation of the splenic vessels should lead to an increased preference for this technique in selected patients undergoing laparoscopic spleen-preserving distal pancreatectomy for benign or low-grade malignant tumors in the body/tail of the pancreas.

    ABSTRACT: Spleen-preserving left pancreatectomy (SPDP) with splenic vessels preservation (SVP) or without (Warshaw technique, WT) has been described with robotic, laparoscopy and open surgery. Nevertheless, significant data on medium- and long-term follow-up are still not available, since data in literature are scarce and the level of evidence is low. In this retrospective study, we describe and compare short and medium term results of spleen-preserving distal pancreatectomy in eight patients. In WT group the duration and the intraoperative bleeding was superior than SVP group. The incidence of perigastric collateral vessels and presence of submucosal varices evidenced at CT scan was 66% in WT group, while only one case occurred in SVP group. The limit of laparoscopic approach is the fact that it needs advanced laparoscopic skills, which might result in intraoperative bleeding and splenectomy. The most of literature considered salvage WT intraoperatively performed in case of classical SVP and not only elective WT. The consequence is that there is no difference in immediate postoperative results (operative time, intraoperative bleeding, hospital stay) that are in favour of SVP because WT is performed only in case of failure in preserving the splenic vessels. In fact when this intervention is performed electively, the procedure time is reduced as well as the intraoperative bleeding. WT is safe and feasible, even if there are not definitive evidences that demonstrate it is superior to classic SVP. RCTs are needed to determine advantages and disadvantages of WT compared to the classic SVP. Copyright © 2015. Published by Elsevier Ltd.

    • "Thus, the impact of somatostatin analogs on postoperative complications in patients undergoing DP remains uncertain and this is reflected by the protocols variations of surveyed centers: half of the centers used PF prophylaxis, with different dosage and route of administration. Splenic vessel preservation seems to be associated with a higher rate of successful spleen preservation and to a reduction in postoperative spleen-related complications such as splenic infarction or abscess [27]. In the present survey, when SP was planned, almost 90 % of the centers preferred the preservation of the splenic vessels compared to the Warshaw technique. "

    ABSTRACT: No data are available about distal pancreatectomy (DP) in Italy, regarding variability of care among centers, and outcome of minimally invasive distal pancreatectomy (MIDP) in a multicenter setting. Hence, a survey was conducted among 20 institutions experienced in pancreatic surgery by the Italian Association for Study of Pancreas. Centers were asked to fill in two questionnaires about (1) general approach and perioperative protocols for DP and MIDP; (2) detailed operative results of MIDP in the period 2010-2011. Results of questionnaire 1: a great variability in perioperative approach was observed: octreotide was used in 50 % of centers, enzyme supplementation in 35 %, postoperative gastric suction in 80 % and oral liquids on day 1 in 55 %. All hospitals used at least one drain and its removal ranged between days 3-5 (in absence of fistula). Differences in type and timing of post-splenectomy vaccinations were recorded. As regards MIDP, 17/20 centers performed laparoscopic or robotic DP. MIDP rate on overall DP varied among centers (range 0-82 %) and it doubled from 2007 (14 %) to 2011 (28 %). Results of questionnaire 2: in the period 2010-2011, 171 MIDP were performed (140 laparoscopic, 31 robotic). Overall conversion rate was 17 %, mean operative time was 230 min and blood loss 285 ml. Mortality was nil and morbidity was 62 %, with 4 % relaparotomies. Pancreatic fistula occurred in 49 % (grade A 35 %, B 14 %). Mean postoperative stay was 9.8 days with 10 % readmission rate. The results indicated a great variability in DP management among Italian centers. Most centers performed MIDP, but MIDP rate on overall DP largely varied among centers. As regards MIDP conversion rate and hospital stay were found to be worse than those in single-institution series.
