This study aimed to share the indications for spleen-preservation and investigate the safety and outcome of LSPDP at our institution. METHODS: A retrospective review of patients who were scheduled to receive laparoscopic surgery for distal pancreatic lesions was conducted. The indications, surgical procedures, intra-operative data, and outcomes of the two procedures were collected and compared by statistical analysis. RESULTS: LDPS and LSPDP were successfully performed in 16 and 21 patients respectively, whereas they were converted to open surgery in 9 patients. There were no significant differences in age, gender, operation time, blood loss, and conversion rate between the LDPS and LSPDP groups. The mean tumor size showed an inter-group difference (5.05 vs 2.53 cm, P<0.001). There were no significant differences in complication and morbidity rates between the two groups. All patients remained alive without recurrence during a follow-up of 9 to 67 months (median 35).CONCLUSION: LSPDP has a morbidity and outcome comparable to LDPS.展开更多

The patients were divided into two groups(concentrated group vs distributed group) according to the distance between the splenic artery's furcation and the splenic hilar region. Then, the anatomical layout, clinicopathologic characteristics, intraoperative variables, and postoperative variables were compared between the two groups.RESULTS: There were 205 patients with a concentrated type(64.7%) and 112 patients with a distributed type(35.3%) Sp A. There were 22 patients(6.9%) with a single branch of the splenic lobar vessels, 250(78.9%) with 2 branches, 43(13.6%) with 3 branches, and 2 patients(0.6%) with multiple branches. Eighty sevenpatients(27.4%) had type?Ⅰ?splenic artery trunk, 211(66.6%) had type Ⅱ, 13(4.1%) had type Ⅲ, and 6(1.9%) had type Ⅳ. The mean splenic hilar lymphadenectomy time(23.15 ± 8.02 vs 26.21 ± 8.84 min; P = 0.002), mean blood loss resulting from splenic hilar lymphadenectomy(14.78 ± 11.09 vs 17.37 ± 10.62 m L; P = 0.044), and number of vascular clamps used at the splenic hilum(9.64 ± 2.88 vs 10.40 ± 3.57; P = 0.040) were significantly lower in the concentrated group than in the distributed group. However, the mean total surgical time, mean total blood loss, and the mean number of harvested splenic hilar lymph nodes were similar in both groups(P > 0.05 for each comparison). There were also no significant differences in clinicopathological and postoperative characteristics between the groups(P > 0.05).CONCLUSION: It is of value for surgeons to know the splenic hilar vascular anatomy when performing LTGSPL. Patients with concentrated type Sp A may be optimal patients for training new surgeons.展开更多

The preoperative clinical T stage was cT2 in 36 patients and cT3 in 72 patients. A prospectively designed database tracked the 108 patients, including the completeness of their medical records and the adequacy of follow-up. Patient clinicopathological char-acteristics, intraoperative and postoperative surgical outcomes, morbidity and mortality, lymph node(LN) dissection, and postoperative follow-up were analysed retrospectively.RESULTS: Laparoscopic spleen-preserving No. 10 lymphadenectomy was successful in all 108 patients. The mean operation time was 169.3 ± 27.1 min, and the mean No. 10 lymphadenectomy time was 20.0 ± 5.7 min. The mean total blood loss was 46.2 ± 11.3 mL, and the mean blood loss from No. 10 lymphadenectomy was 14.3 ± 3.8 mL. The mean postoperative hospital stay was 11.9 ± 6.0 d. The intraoperative and postoperative morbidity rates were 3.7% and 12.0%, respectively; however, there was no postoperative mortality. A mean of 44.4 ± 17.6 LNs were retrieved from each specimen, including 3.0 ± 2.4 No. 10 LNs. Three patients(2.8%) with cT3 cancer had LN metastasis of the splenic hilus, including two patients with pathological T3(pT3) and one patient with pathological T4a(pT4a) tumours, all located in the greater curvature. No splenic hilar LNs metastasis was evident in the patients with pT1 and pT2 tumours. At a median follow-up time of 18 mo(range, 12 to 23 mo), all patients were alive and none had experienced recurrent or metastatic disease.CONCLUSION: Laparoscopic spleen-preserving No. 10 lymphadenectomy is feasible and effective to treat AUGC. Routine No. 10 lymphadenectomy may be unnecessary for AUGC without serosa invasion, unless T3 tumours are located in the greater curvature.展开更多

The aim of this study was to evaluate the postoperative clinical outcomes of patients undergoing both methods. DATA SOURCES: Database search of PubMed, Embase, Scopus, Cochrane, and Google Scholar was performed (2000-2014); key bibliographies were reviewed. Qualified studies compar- ing patients undergoing SPDP with either SVP or WP, and as- sessing postoperative complications were included. Calculated pooled risk ratio (RR) with the corresponding 95% confidence interval (CI) by random effects methods were used in the meta-analyses. RESULTS: The search yielded 215 studies, of which only 14 observational studies met our selection criteria. The studies included 943 patients in total; 652 (69%) underwent SVP and 291 (31%) underwent WP. Overall, there was a lower incidence of splenic infarction (RR=0.17; 95% Ch 0.09-0.33; P〈0.001), gastric varices (RR=0.16; 95% Ch 0.05-0.51; P=0.002), and intra/postoperative splenectomy (RR=0.20; 95% Ch 0.08-0.49; P〈0.001) in the SVP group. There was no difference in in- cidence of pancreatic fistula (WP vs SVP, 23.6% vs 22.9%;P=0.37), length of hospital stay, operative time or blood loss. There was moderate cross-study heterogeneity. CONCLUSIONS: SVP is a safe, efficient and feasible technique that may be used to preserve the spleen. WP may be more suit- able for large tumors dose to the splenic hilum or those associ- ated with splenomegaly. Randomized clinical trials are justified to examine the long-term benefits of SVP-SPDP.展开更多

Diseases included splenic injury in 171 cases, portal hypertension in 9 cases, splenic cyst in 10 cases, and the lesion of pancreatic body and tail in 21 cases.RESULTS: All the cases were cured, and 129 patients were followedup from 3 months to 3 years with the leukocyte phagocytosis test, detection of immunoglubin, CT, 99mTc scanning and ultrasonogrsphy. The results were satisfactory.CONCLUSION: The operations with preserving spleen were safe, feasible, and worth of clinical application.展开更多

The aim of this research was to study the feasibility,safety and clinical effects of spleen and splenic vessel-preserving distal pancreatectomy.Methods A retrospective review was performed for 26 patients undergoing distal pancreatectomy for benign or low grade malignant disease with splenectomy (n=13) or splenic preservation (n=13) at the First Hospital of Sun Yat-sen University and Guangdong General Hospital in Southern China from May 2002 to April 2009.Results All 26 pancreatectomies with splenectomy or splenic preservation were performed successfully. There was no statistically significant difference between two groups in mean operative time ((172±47) minutes vs. (157±52) minutes, P >0.05), intraoperative estimated blood loss ((183±68) ml vs. (160±51) ml, P >0.05), incidence of noninfectious and infection complication and mean length of postoperative hospital stay ((10.1±2.2) days vs. (12.1 ±4.6) days, P >0.05). The platelet counts examined one week after operation were significantly higher in the distal pancreatectomy with splenectomy group than the other group ((37.3±12.8)×109/L vs. (54.7±13.2)×109/L, P <0.05).Conclusions Spleen-preserving distal pancreatectomy appears to be a feasible and safe procedure. In selected cases of benign or low-grade malignant disease, spleen-preserving distal pancreatectomy is recommended.展开更多
