This study aimed at reporting the technical aspects of caval reconstruction using peritoneal patch during extended liver resections. Methods All consecutive patients who underwent extended liver resection associated with anterolateral caval reconstruction using a peritoneal patch from 2016 to 2019 were included in this study. Technical insights, intra-operative details, short and long-term results were reported. Results Overall six patients underwent caval reconstruction using peritoneal patch under total vascular exclusion. Half of them required veno-venous bypass. Caval involvement ranged from 30 to 50% of the circumference and from 5 to 7 cm of the length of the IVC. Caval reconstructions was performed using a peritoneal patch harvested from the falciform ligament in four cases and from the right pre-renal peritoneum and right part of the diaphragm in one Case each. Three cases underwent associated reimplantation the remnant hepatic vein. Median intra-operative blood loss and TVE duration were 500 ml and 41 min, respectively. One case experienced a severe complication (liver failure leading to death). R0 resection was achieved in all patients. All patients had patent IVC and remnant hepatic vein at last follow-up and none was on long-term therapeutic anticoagulation. Conclusion Caval reconstruction using a peritoneal patch in patients undergoing extended liver resection is feasible and cost-effective and associated with excellent long-term results.Gallbladder cancer (GBCA) is a rare and fatal disease and the majority of patients presents with advanced stage. Surgical resection associated with lymphadenectomy is the only chance for cure. For patients in stages III and IV, extended resection is the only treatment to achieve R0 margins. For GBCA invading the hepatoduodenal ligament and pancreatoduodenal region, the resection of extrahepatic bile duct and pancreas is necessary. Hepatopancreatoduodenectomy (HPD) represents the most complex and challenging procedure in the hepatopancreatobiliary region. Kuno at the Cancer Institute Hospital Tokyo performed the first HPD in Japan in 1974 and in 1980 Takasaki presented five cases and the 30-day mortality was 60%. After that, other countries started to perform the procedure including United States and Brazil. The main complications are liver failure and pancreatic fistula. Advancements in perioperative care, surgical technique, medical instruments and postoperative at intensive care unit have resulted in reduction in morbidity and mortality. The use of portal vein embolization is indicated to increase the liver volume in patients with insufficient remnant. Preoperative biliary drainage can prevent cholangitis and improve hepatic function. This procedure should be recommended before extended HPD in jaundiced patients. Operative results with mortality rates below 5% at high volume centers suggest that HPD should be performed at centers with expertise in hepatopancreatobiliary surgery.In spite of early adoption of the brain death legislation, and all efforts at promoting deceased donation, various social, economic and cultural factors have acted as road blocks to the furthering of deceased donor liver transplantation (DDLT) in most Asian societies. On the other hand, Asian liver transplant centers have been the pioneers, innovators, and technical advancement catalysts for the world to follow, especially with regards to living donor liver transplantation (LDLT). With some high volume centers performing more than 200 LDLTs a year with good outcomes in the donor and recipient, techniques to expand the living donor pool have also been adopted like ABO-incompatible, paired exchange and dual lobe living donor liver transplants. Although large multicenter, and registry data as regards safety and outcomes of minimally invasive donor hepatectomy are awaited, expert centers have pioneered, and now regularly perform purely laparoscopic and robotic living donor hepatectomies, especially in Korea.Background Postoperative cognitive dysfunction (POCD) is a complication of central nervous system in patients after surgery. Edaravone as a brain-protective agent may have protective effect on postoperative cognitive function. The study was designed to explore the effects of edaravone on postoperative cognitive function in elderly patients undergoing hip joint replacement surgery and potential mechanism. Patients and methods Patients undergoing hip joint replacement surgery were randomly allocated into 2 groups the edaravone group (group E) and the control group (group C). Group E received intravenous edaravone at a dose of 0.5 mg/kg after induction of anesthesia, while group C received normal saline. The cognitive function was evaluated with the Mini-Mental State Examination (MMSE) 1day before surgery,3 days and the 7 days after surgery. Patients' plasma samples were collected to detect the levels of S100β protein (S100β), interleukin-6 (IL-6), matrix metalloproteinase-9 (MMP-9), superoxide dismutase (SOD) and malondialdehyde (MDA) before the induction of anesthesia, at the end of surgery and on postoperative day 3. Results The MMSE scores in group E were higher than those of group C 3 days after surgery (25.98 ± 1.99 vs 24.86 ± 1.86, p = 0.003). There were remarkable rises (p less then 0.05) in plasma IL-6, S100βand MMP-9 levels at the end of surgery and on postoperative day 3 in the two groups, however, edaravone pretreatment could reduce these levels to a certain extent compared with group C (p less then 0.05).In group E, the SOD concentration was higher at the end of surgery (16.03 ± 2.46U/ml vs. 13.65 ± 2.53U/ml, p = 0.0001), while the MDA level was lower on postoperative day 3 than those in group C (7.01 ± 2.37 nmol/ml vs. 11.34 ± 3.18 nmol/ml, p = 0.0001). Conclusion The results indicated that preoperative intervention with edaravone may improve the postoperative cognitive function in elderly patients undergoing hip joint replacement surgery.Background Research has shown that patients who develop a postoperative intra-abdominal abscess (PIAA) after appendectomy have a greater number of health care visits with drain placement. Our institution developed an algorithm to limit drain placement for only abscesses with a size >20 cm2. We sought to determine the adherence to and effectiveness of this algorithm. Methods This prospective observational study included patients aged 2-18 y old who developed a PIAA from September 2017 to June 2019. Outcomes were compared between patients with a small or large abscess. Analysis was performed in STATA; P less then 0.05 was significant. Results Thirty patients were included. The median age was 10.6 y (7, 11.7); 60% were men, and 60% were Caucasian. The median duration of symptoms before diagnosis of appendicitis was 3 d (2, 6). Thirteen patients (43%) were diagnosed with a PIAA while still inpatient, and 17 (57%) were readmitted at a later date. After algorithm implementation, 95% (n = 19) of patients with a large abscess had aspiration ± drain placement, whereas 30% (n = 3) with a small abscess underwent drainage. Length of stay after abscess diagnosis, total duration of antibiotics, and number of health care visits were the same between groups. One patient with a small abscess required reoperation for an obstruction, whereas one patient with a large abscess that was drained was readmitted for a recurrent abscess. Conclusions Small PIAA can be successfully managed without intervention. Our proposed algorithm can assist in determining which patients can be treated with antibiotics alone.Background The present literature is conflicting regarding the management of microinvasive ductal carcinoma in situ (miDCIS) as to following recommendations for DCIS (margin status, surgical axillary staging, and possible observation) versus invasive breast cancer. We hypothesize that miDCIS represents more aggressive disease than pure DCIS. Methods We performed a retrospective review of female miDCIS patients compared with age-matched cohorts of DCIS and T1b/c patients with invasive breast cancer. We collected demographic, clinicopathologic, treatment, and outcome information. Analysis of variance or Kruskal-Wallis tests were used to analyze continuous variables and chi-square or Fisher's exact tests for categorical variables. Survival outcomes were analyzed using Kaplan-Meier curves. Results We included 375 patients (125 in each group) with median age 59 y (range 33-91 y). miDCIS tumors were more likely to be hormone receptor negative and human epidermal growth factor receptor 2 positive compared with DCIS or invasive ductal carcinoma (IDC; all P less then 0.001). Subgroup analysis by miDCIS focality demonstrated no significant differences. The number of involved lymph nodes was not significantly different from DCIS patients but was significantly fewer than invasive cancer patients. Of 115 miDCIS patients (88%) staged with sentinel lymph node biopsy, eight (7%) had nodal metastases. Six miDCIS patients (5%) were treated with adjuvant chemotherapy. Over a median follow-up of 23.3 mo, there were no significant differences in local or distant recurrence. Conclusions Based on our results, miDCIS has more aggressive pathologic features compared with DCIS and warrants surgical treatment and nodal staging similar to the management of IDC. In addition, similar to IDC, nodal and receptor status may influence medical management.The mammary gland is a highly dynamic tissue that undergoes repeated cycles of growth and involution during pregnancy and menstruation. It is also the site from which breast cancers emerge. Organoids provide an in vitro model that preserves several of the cellular, structural, and microenvironmental features that dictate mammary gland function in vivo and have greatly advanced our understanding of glandular biology. Their tractability for genetic manipulation, live imaging, and high throughput screening have facilitated investigation into the mechanisms of glandular morphogenesis, structural maintenance, tumor progression, and invasion. Opportunities remain to enhance cellular and structural complexity of mammary organoid models, including incorporating additional cell types and hormone signaling.Background Oral and maxillofacial surgeons are occupationally exposed to ocular injuries via bodily fluid (ie, blood or saliva), which can carry substantial latent risks, both bacterial and viral. The aim of this study was to determine the prevalence of ocular injury and infection among oral and maxillofacial surgeons during outpatient procedures. Methods Data were collected from a consecutive series of 500 surgeries conducted by 26 resident surgeons via a questionnaire. Responses were categorized into two groups Group I did not indicate an eye injury, and Group II did indicate an eye injury. Results Of 500 procedures, 161 resulted in ocular injuries, a rate of 32.2 injuries per 100 person-procedures. Educated participants experienced eye injuries at a significantly higher rate than those who were uneducated (23.33% vs. 15.11%; P=0.022). Those not using eye protection experienced eye injuries at a significantly higher rate than those using eye protection (23.32% vs. 2.33%; P less then 0.001).
