Cardiac-type total anomalous pulmonary venous return is not benign

ObjectiveThe objective of this study was to investigate the association between morphological variation and postsurgical pulmonary vein (PV) stenosis (PPVS) in patients with cardiac total anomalous pulmonary venous connection (TAPVC).MethodsThis single-center, retrospective study included 168 pediatric patients who underwent surgical repair of cardiac TAPVC from 2013 to 2019 (connection to the coronary sinus [CS], n = 136; connection directly to the right atrium [RA], n = 32). Three-dimensional computed tomography modeling and geometric analysis were performed to investigate the morphological features; their relevance to the PPVS was examined.ResultsThe connection type had no association with PPVS (CS type: 18% vs right atrial type: 19%; P = .89) but there was a higher incidence of PPVS in patients with a single PV orifice than > 1 orifice (P < .001). Confluence-to-total PV area ratio (hazard ratio, 4.78, 95% CI, 1.86-12.32; P = .001) and length of drainage route (hazard ratio, 1.22; 95% CI, 1.14-1.31; P < .001) had a 4- and 1-fold increase in the risk for PPVS in the CS type after adjustment for age and preoperative pulmonary venous obstruction. In the right atrial type, those with anomalous PV return to the RA roof were more likely to develop PPVS than to the posterior wall of the RA (P < .001).ConclusionsThe number of inter-junction PV orifice correlated with PPVS development in cardiac TAPVC. The confluence-to-total PV ratio, length of drainage route, and anomalous PV return to the RA roof are important predictors for PPVS. Morphological subcategorization in this clinical setting can potentially assist in surgical decision-making.     

Risk factors and management of stoma-related obstruction after laparoscopic colorectal surgery with diverting ileostomy

BackgroundStoma-related obstruction (SRO) is defined as small bowel obstruction occurring around the limbs of diverting ileostomy (DI). This study was aimed to investigate the incidence, risk factors, and management of SRO after laparoscopic colorectal surgery with DI creation.MethodsThis study included 155 patients who underwent laparoscopic colorectal surgery with DI creation for rectal cancer (n = 138), ulcerative colitis (UC) (n = 14), and familial adenomatous polyposis (FAP) (n = 3) between 2011 and 2019. Univariate and multivariate analyses were performed to identify the risk factors of SRO.ResultsThe incidence of SRO was 7.7% (n = 12), and it was significantly lower (P < 0.01) in patients with lower anterior resection or intersphincteric resection (4.3%) than in those with ileal-pouch anal anastomosis (IPAA) (35.2%). The multivariate analysis revealed that IPAA was independently associated with the development of SRO (P = 0.001; odds ratio, 9.4; 95% confidence interval, 2.5–35.4). Eleven of 12 patients (92%) with SRO required trans-stomal tube decompression, and 8 of those (67%) underwent early stoma closure.ConclusionIPAA was an independent risk factor of SRO in laparoscopic colorectal surgery with DI creation. Early stoma closure was needed in most cases of SRO.     

Buried Bumper Syndrome: A common complication of levodopa intestinal infusion for Parkinson disease

BackgroundPercutaneous endoscopic gastrostomy (PEG) is required for Levodopa/Carbidopa Intestinal Gel (LCIG) delivery in patients with advanced Parkinson's disease (PD) as well as for enteral feeding in a variety of neurological disorders. Buried Bumper Syndrome (BBS) is a serious complication of PEG. The frequency of BBS in patients receiving LCIG treatment has never been reported.ObjectivesTo compare the frequency of BBS in patients on LCIG treatment or on enteral feeding over the past 12 years and identify possible risk factors.MethodsWe reviewed prospectively recorded data from 2009 to 2020 on two case-series: LCIG-treated PD patients and non-PD patients on enteral nutrition. We identified all BBS incidences. Patients’ characteristics, clinical manifestations, BBS management, possible risk factors and outcomes were analyzed.ResultsDuring the 12 years, 35 PD patients underwent PEG insertion for LCIG infusion, and 123 non-PD patients for nutritional support. There were eight cases of BBS in six PD patients (17.1%). Six of them were effectively managed without treatment discontinuation. Of the enteral feeding patients, only one developed BBS (0.8%) (p < 0.001). We identified inappropriate PEG site aftercare, weight gain, early onset PD, longer survival, treatment duration, dementia and PEG system design as potential risk factors for BBS development.ConclusionsBBS occurs more frequently in LCIG patients than in patients receiving enteral feeding. If detected early, it can be successfully managed, and serious sequalae or treatment discontinuation can be avoided. Regular endoscopic follow-up visits of LCIG-treated patients and increased awareness in patients and clinicians are recommended.     

预防性静滴钾离子、镁离子对急性心梗后并发室性心律失常的预防作用

目的 探究预防性静滴钾离子、镁离子对急性心梗后并发室性心律失常的预防作用。方法 选择2015年1月-2018年1月于西宁市第一人民医院进行治疗的78例急性心肌梗死患者为研究对象，按照随机数字表法将其均分为观察组与对照组，每组各39例患者。对照组患者进行常规急性心梗治疗，观察组患者在对照组基础上加用门冬氨酸钾镁进行治疗，对比两组治疗有效率，对比两组治疗前后血液流变学指标纤维蛋白原（Fib）、凝血酶原时间（PT）、血小板计数（Plt），对比两组治疗期间不良反应发生率及心律失常发生率。结果 治疗后，观察组患者治疗有效率为87.18%，对照组为76.92%，两组对比差异具有统计学意义（P<0.05）。治疗前两组患者Fib、PT以及Plt水平对比差异不具有统计学意义；治疗后，两组患者Plt及Fib水平低于治疗前，PT水平高于治疗前，差异有统计学意义（P<0.05）；治疗后观察组患者Plt及Fib水平低于对照组，PT水平高于对照组（P<0.05）。观察组患者不良反应发生率稍高于对照组，但对比差异不具有统计学意义。观察组心律失常发生率为7.69%，对照组为15.38%，两组对比差异具有统计学意义（P<0.05）。结论 预防性静滴钾离子与镁离子能够显著降低急性心梗患者心律失常发生率，同时有利于提高治疗有效率，改善其血流变指标，且安全性较高。     

The practical assessment and management of bladder outflow obstruction

The initial management of bladder outflow obstruction typically related to benign prostatic hyperplasia (BPH) falls to a large extent within the remit of general practice. Referral onwards to secondary care typically arises following the failure to respond to conservative measures or when complications have supervened; the most significant of which is urinary retention. In the hospital setting, anaesthesia, constipation and immobility are the common precipitants. What follows is a practical guide to the management of these situations and provides an overview of the conservative, medical, minimally invasive and surgical treatments available.

Prenatal Sonography in Suspected Proximal Gastrointestinal Obstructions: Diagnostic Accuracy and Neonatal Outcomes

BackgroundThe purpose of this study was to assess diagnostic accuracy and neonatal outcomes in fetuses with a suspected proximal gastrointestinal obstruction (GIO).MethodsAfter IRB approval, a retrospective chart review was conducted on prenatally suspected and/or postnatally confirmed cases of proximal GIO at a tertiary care facility (2012–2022). Maternal-fetal records were queried for presence of a double bubble ± polyhydramnios, and neonatal outcomes were assessed to calculate the diagnostic accuracy of fetal sonography.ResultsAmong 56 confirmed cases, the median birthweight and gestational age at birth were 2550 g [interquartile range (IQR) 2028–3012] and 37 weeks (IQR 34–38), respectively. There was one (2%) false-positive and three (6%) false-negatives by ultrasound. Double bubble had a sensitivity, specificity, positive predictive value, and negative predictive value for proximal GIO of 85%, 98%, 98%, and 83%, respectively. Pathologies included 49 (88%) with duodenal obstruction/annular pancreas, three (5%) with malrotation, and three (5%) with jejunal atresia. The median postoperative length of stay was 27 days (IQR 19–42). Cardiac anomalies were associated with significantly higher complications (45% vs 17%, p = 0.030).ConclusionsIn this contemporary series, fetal sonography has high diagnostic accuracy for detecting proximal gastrointestinal obstruction. These data are informative for pediatric surgeons in prenatal counseling and preoperative discussions with families.Level of EvidenceDiagnostic Study, Level III.
