Abstract
Purpose: Dissecting and ligating the splenic artery is crucial for bleeding control during laparoscopic splenectomy (LS). However, for patients with portal hypertension from liver cirrhosis, it is difficult for identification and ligation because the splenic vessel is circuitous and dilated. The aim of this study was to describe a simple technique of constructing a tunnel behind the tail of the pancreas for occluding the splenic vessels during LS in patients with portal hypertension. Materials and Methods: The clinical data of 61 patients who underwent LS from April 2016 to January 2017 were retrospectively analyzed. In 27 patients, the tunnel construction (TC) behind the tail of the pancreas approach was performed owning to difficulty in dissecting and ligating the splenic artery (TC group), including 17 patients who received the TC method directly and 10 patients who received the TC method after trying to dissect the splenic artery. The remaining 34 patients underwent traditional ligating of the splenic artery (LA group). The peri- and postoperative outcomes of operative time, blood loss, conversion rate, postoperative oral diet intake, postoperative hospital stay, and postoperative complication rate of the two groups were analyzed. All the operations were completed by the same group of surgeons. Results: All 61 operations were successfully completed. Compared with patients in the LA group, patients in the TC group had less blood loss (120.37 ± 40.74 mL versus 162.65 ± 87.47 mL; t = -2.317, P = .024). There was no statistical difference of operative time, conversion rate, complication rate, postoperative hospital stays, and follow-up between the two groups. Conclusions: The technique of constructing a tunnel behind the tail of the pancreas for occluding the splenic vessels was effective and safe in those patients whose splenic artery was difficult to dissect and ligate.

Abstract
OBJECTIVES To review the evidence regarding the outcomes of laparoscopic techniques in cases of splenomegaly. BACKGROUND Endoscopic approaches such as laparoscopic, hand-assisted laparoscopic, and robotic surgery are commonly used for splenectomy, but the advantages in cases of splenomegaly are controversial. REVIEW METHODS We conducted a systematic review using PRISMA guidelines. PubMed/MEDLINE, ScienceDirect, Scopus, Cochrane Library, and Web of Science were searched up to February 2020. RESULTS Nineteen studies were included for meta-analysis. In relation to laparoscopic splenectomy (LS) versus open splenectomy (OS), 12 studies revealed a significant reduction in length of hospital stay (LOS) of 3.3 days (p = <0.01) in the LS subgroup. Operative time was higher by 44.4 min (p < 0.01) in the LS group. Blood loss was higher in OS 146.2 cc (p = <0.01). No differences were found regarding morbimortality. The global conversion rate was 19.56%. Five studies compared LS and hand-assisted laparosocpic splenectomy (HALS), but no differences were observed in LOS, blood loss, or complications. HALS had a significantly reduced conversion rate (p < 0.01). In two studies that compared HALS and OS (n = 66), HALS showed a decrease in LOS of 4.5 days (p < 0.01) and increase of 44 min in operative time (p < 0.01), while OS had a significantly higher blood loss of 448 cc (p = 0.01). No differences were found in the complication rate. CONCLUSION LS is a safe approach for splenomegaly, with clear clinical benefits. HALS has a lower conversion rate. Higher-quality confirmatory trials with standardized splenomegaly grading are needed before definitive recommendations can be provided. Prospero registration number: CRD42019125251.

Abstract
Background Systemic protumorigenic effects have been noted after radiofrequency ablation (RFA) of normal liver and have been linked to an interleukin 6/signal transducer and activator of transcription 3 (STAT3)/hepatocyte growth factor (HGF)/tyrosine-protein kinase Met (c-Met)/vascular endothelial growth factor (VEGF) cytokinetic pathway. Purpose To elucidate kinetics of RFA protumorigenic effects on intrahepatic metastatic implantation and growth and determine potential molecular targets for pharmacologic suppression of these effects. Materials and Methods An intrahepatic metastasis model was established by implanting CT26 and MC38 tumor cells into 216 7-8-week-old male Balb/C and C57BL6 mice, respectively, by means of splenic injection. Between June 2017 and March 2019, mice underwent tumor injection, followed 24 hours later by either standardized RFA (70°C ± 1, 5 minutes, 1-cm tip) or a sham procedure (needle placement without heating) (12 animals per arm, n = 48). Next, RFA or sham procedures were performed, followed by splenic tumor cell injection at 1 day, 3 days, or 7 days later (six animals per arm, n = 72). Finally, PHA-665752 and S3I-201 were used to block c-Met or STAT3, respectively, prior to either RFA or sham treatment (six animals per arm, n = 96). Livers were harvested at 14 days for CT26 and 21days for MC38 for tumor quantification. Ki-67 and CD34 immunohistochemistry measured proliferative indexes and microvascular density, respectively. Data were compared with analysis of variance and the two-tailed Student t test. Results RFA performed after tumor cell injection induced increased metastatic tumor number (103 ± 45 vs 52 ± 44 [CT26], P = .009 and 87 ± 51 vs 39 ± 20 [MC38], P = .007), cellular proliferation (P < .001 for both), and intratumoral neovascularization (P < .001 for both), compared with the sham procedure. Tumor cell injection performed 1 day and 3 days after RFA also increased these indexes (P < .05), while no difference was demonstrated for cell injection 7 days after RFA (P > .05). Adjuvant c-Met or STAT3 inhibition reduced intrahepatic metastatic parameters after RFA to baseline (P < .03), equivalent to the sham group (P > .05). Conclusion Radiofrequency ablation of normal liver promotes intrahepatic metastatic implantation and increased growth over a short-lived (1-3 days) temporal window in animal models. This phenomenon can be potentially neutralized with specific inhibition of pathways including hepatocyte growth factor/tyrosine-protein kinase Met and signal transducer and activator of transcription 3. © RSNA, 2019 Online supplemental material is available for this article.

Urbanicity and lifestyle risk factors for cardiometabolic diseases in rural Uganda: a cross-sectional study. PLoS Med 2014; 11:e1001683. [PMID: 25072243 PMCID: PMC4114555 DOI: 10.1371/journal.pmed.1001683] [Citation(s) in RCA: 48] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/25/2013] [Accepted: 06/18/2014] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Urban living is associated with unhealthy lifestyles that can increase the risk of cardiometabolic diseases. In sub-Saharan Africa (SSA), where the majority of people live in rural areas, it is still unclear if there is a corresponding increase in unhealthy lifestyles as rural areas adopt urban characteristics. This study examines the distribution of urban characteristics across rural communities in Uganda and their associations with lifestyle risk factors for chronic diseases. METHODS AND FINDINGS Using data collected in 2011, we examined cross-sectional associations between urbanicity and lifestyle risk factors in rural communities in Uganda, with 7,340 participants aged 13 y and above across 25 villages. Urbanicity was defined according to a multi-component scale, and Poisson regression models were used to examine associations between urbanicity and lifestyle risk factors by quartile of urbanicity. Despite all of the villages not having paved roads and running water, there was marked variation in levels of urbanicity across the villages, largely attributable to differences in economic activity, civil infrastructure, and availability of educational and healthcare services. In regression models, after adjustment for clustering and potential confounders including socioeconomic status, increasing urbanicity was associated with an increase in lifestyle risk factors such as physical inactivity (risk ratio [RR]: 1.19; 95% CI: 1.14, 1.24), low fruit and vegetable consumption (RR: 1.17; 95% CI: 1.10, 1.23), and high body mass index (RR: 1.48; 95% CI: 1.24, 1.77). CONCLUSIONS This study indicates that even across rural communities in SSA, increasing urbanicity is associated with a higher prevalence of lifestyle risk factors for cardiometabolic diseases. This finding highlights the need to consider the health impact of urbanization in rural areas across SSA. Please see later in the article for the Editors' Summary.
