RESUMEN

BACKGROUND: There is no consensus on the pancreatic transection during distal pancreatectomy (DP) to reduce postoperative pancreatic fistula (POPF). This meta-analysis aimed to evaluate the effects of a reinforced stapler on the postoperative outcomes of DP. METHODS: We systematically searched electronic databases and bibliographic reference lists in The PubMed/MEDLINE, Google Scholar, Cochrane Library's Controlled Trials Registry and Database of Systematic Reviews, Embase, and Scopus. Review Manager Software was used for pooled estimates. RESULTS: Seven eligible studies published between 2007 and 2021 were included with 553 patients (267 patients in the reinforced stapler group and 286 patients in the standard stapler group). The reinforced stapler reduced the POPF grade B and C (OR = 0.33; 95% CI [0.19, 0.57], p < 0.01). There was no difference between the reinforced stapler group and standard stapler group in terms of mortality rate (OR = 0.39; 95% CI [0.04, 3.57], p = 0.40), postoperative haemorrhage (OR = 0.53; 95% CI [0.20, 1.43], p = 0.21), and reoperation rate (OR = 0.91; 95% CI [0.40, 2.06], p = 0.82). CONCLUSIONS: Reinforced stapling in DP is safe and seems to reduce POPF grade B/C with similar mortality rates, postoperative bleeding, and reoperation rate. The protocol of this systematic review with meta-analysis was registered in PROSPERO (ID: CRD42021286849).

RESUMEN

IMPORTANCE: While oncological outcomes of early salvage total mesorectal excision (sTME) after local excision (LE) have been well studied, the impact of LE before TME on postoperative outcomes remains unclear. We aimed to compare early sTME with a primary TME for rectal cancer. METHODS: Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines with the random-effects model were adopted using Review Manager Version 5.3 for pooled estimates. RESULTS: We retrieved eleven relevant articles including 1728 patients (350 patients in the sTME group and 1438 patients in the TME group). There was no significant difference between the two groups in terms of mortality (OR = 0.90, 95%CI [0.21 to 3.77], p = 0.88), morbidity (OR = 1.19, 95%CI [0.59 to 2.38], p = 0.63), conversion to open surgery (OR = 1.34, 95%CI [0.61 to 2.94], p = 0.47), anastomotic leak (OR = 1.38, 95%CI [0.50 to 3.83], p = 0.53), hospital stay (MD = 0.23 day, 95%CI [- 1.63 to 2.10], p < 0.81), diverting stoma rate (OR = 0.69, 95%CI [0.44 to 1.09], p = 0.11), abdominoperineal resection rate (OR = 1.47, 95%CI [0.91 to 2.37], p = 0.11), local recurrence (OR = 0.94, 95%CI [0.44 to 2.04], p = 0.88), and distant recurrence (OR = 0.88, 95%CI [0.52 to 1.48], p = 0.62). sTME was associated with significantly longer operative time (MD = 25.62 min, 95%CI[11.92 to 39.32], p < 0.001) lower number of harvested lymph nodes (MD = - 2.25 lymph node, 95%CI [- 3.86 to - 0.65], p = 0.006), and higher proportion of incomplete TME (OR = 0.25, 95%CI [0.11 to 0.61], p = 0.002). CONCLUSIONS: sTME is not associated with increased postoperative morbidity, mortality, or local recurrence. However, the operative times are longer and yield a poor specimen quality.

RESUMEN

This meta-analysis of randomized clinical trials (RCT) aimed to compare peritoneal irrigation followed by suction with aspiration only during laparoscopic surgery for complicated appendicitis (LA). PRISMA guidelines with the random-effects model were adopted using Review Manager Version 5.3 for pooled estimates. We retained six eligible RCT published between 2012 and 2019. They involved a total of 1019 patients (541 patients in the aspiration group and 478 patients in the irrigation group). Aspiration only during LA is associated with shorter operative time (MD = 8.50 min, 95% CI [- 12.97 to - 4.02], p = 0.0002) and lower reoperation rate (OR = 0.37 95% CI [0.14-0.96], p = 0.04). There was no difference between aspiration group and irrigation group in terms of Intraperitoneal abscess (IPA) (OR = 0.99 95% CI [0.54-1.81], p = 0.95), morbidity rate (OR = 1.14 95% CI [0.44-2.98], p = 0.79), wound infection (OR = 0.94 95% CI [0.20-4.40], p = 0.94), and hospital stay (MD = 0.65 day, 95% CI [- 0.52 to 1.82], p = 0.27). Irrigation during LA prevents post-appendectomy IPA in neither adults nor pediatric patients. However, it lengthens the operative time and involves a higher reoperation rate.

RESUMEN

BACKGROUND: Population-based data on the development of second malignant neoplasms (SMNs) following the diagnosis of hepatocellular carcinoma (HCC) are uncommon. We evaluated this clinical vignette in HCC patients within the Surveillance, Epidemiology and End Results (SEER) database. METHODS: The SEER database (1973-2012) was queried using the SEER*Stat program to determine the clinico-pathological features of HCC patients with more than one year survival who developed SMNs. Standardized incidence ratios (SIRs) were calculated to determine the risk of each type of subsequent cancers. Relative risk was assessed to determine the impact of liver transplantation on the development of second malignant neoplasms. RESULTS: On SIR analysis, the following sites have an enhanced risk of developing an SMN following the diagnosis of HCC: tongue, anal canal, liver, lung, kidney, thyroid, non-Hodgkin lymphoma (both nodal and extra-nodal disease) and acute monocytic leukemia (P < 0.05 for all sites). A significantly higher RR was found for the development of lung cancer (RR = 2.096), thyroid cancer (RR = 3.045) and non-Hodgkin lymphoma (RR = 3.822) among patients who underwent liver transplantation compared to those who did not (P < 0.05). CONCLUSION: There is an excess risk for developing a number of SMNs among patients diagnosed with HCC.

RESUMEN

Orthotopic liver transplantation (LTP) is nowadays a standard procedure, and provides the chance of survival of patients with end-stage non-treatable chronic liver disease or acute liver failure. Despite long-term survival with a good quality of life in the majority of patients, about 20% develop early allograft dysfunction (EAD), which leads to death or the need for re-transplantation. Therefore, the early diagnosis of EAD and evaluation of its risk factors are very important. Many primary pathological processes leading to EAD are accompanied by the release of different mediators and by a change of biochemical parameters detectable in the peripheral blood. The aim of this study was to investigate cytokines as well as soluble mediators in the serum of patients with and without EAD from our LTP bank, and to evaluate their predictive and prognostic values for EAD. We demonstrated for the first time that the level of IFNγ during the nearest preoperative period may serve as a predictive parameter for EAD. We additionally found that IL-10 and CXCL10 (IP-10) levels in the early postoperative period can be prognostic for EAD. We believe our data expand the spectrum of predictive and prognostic parameters for EAD in LTP.

RESUMEN

BACKGROUND: The Model for End-Stage Liver Disease (MELD) score is a tool for assessment of the degree of hepatic insufficiency/failure. Quinolinic acid (QuinA) is a tryptophan metabolite produced by activated macrophages. Here we investigate whether the degree of systemic inflammation (QuinA, neopterin, CRP and IL-6) correlates with clinical liver dysfunction according to the MELD Score. METHOD: Ninety-four patients with liver cirrhosis were categorized into 2 groups according to baseline MELD score (group I, MELD <20, n = 61, and group II, MELD ≥20, n = 33). RESULTS: Serum levels of QuinA, neopterin, CRP, and IL-6 significantly correlated with MELD score (r = 0.77, 0.75, 0.57, and 0.50; p < 0.0001, respectively). Patients of group II had significantly higher serum levels of QuinA, neopterin, CRP, and IL-6 than group I (p0.0001). ROC curve analysis showed that QuinA and neopterin are more sensitive markers for severity of liver disease than established markers of inflammation such as CRP and IL-6 (sensitivity = 86% and 79%, respectively) (AUC=0.89 and 0.89, respectively). QuinA provided the most sensitive index with regard to the identification of patients with hepatic encephalopathy. CONCLUSION: Serum levels of QuinA reflect the degree of liver dysfunction. Moreover, high levels of QuinA may serve as a sensitive indicator of hepatic encephalopathy.
