BACKGROUND: Chronic pain affects 10%-12% of patients after inguinal hernia repairs. Some have suggested that less foreign material may theoretically prevent pain. If the prevalence of chronic pain is less after nonmesh repairs, selected hernias might be repaired without mesh. Our aim was to clarify if nonmesh repairs are superior to mesh repairs regarding chronic pain. METHODS: For this systematic review, searches were conducted in five databases. The main outcome was chronic pain reported a minimum of six months after mesh and nonmesh repair in adult patients with a primary inguinal hernia...

BACKGROUND: Retraction of previously published scientific articles is an important mechanism to preserve the integrity of scientific work. This study analyzed retractions of previously published articles from surgery journals. METHODS: We searched for retracted articles in the 100 surgery journals with the highest SJR2 indicator grades. RESULTS: We found 130 retracted articles in 49 journals (49%). Five or more retracted articles were published in 8 journals (8%)...

BACKGROUND: Whether patients undergoing hemodialysis have greater risks of mortality and morbidity after hepatic resection remains unclear. METHODS: We used the Diagnosis Procedure Combination database, a national inpatient database in Japan, to identify patients who underwent hepatic resection from July 2010 to March 2014. Propensity scorematching analysis was performed to compare morbidity and mortality between patients with and without hemodialysis. RESULTS: Of 53,651 eligible patients, 498 (0...

BACKGROUND: The Cancer and Leukemia Group B 9,343 demonstrated that postoperative radiation can be safely omitted in women ≥70 years who underwent breast-conserving therapy for clinical stage I (T1N0M0) estrogen receptor positive breast cancer treated with antihormonal therapy. Whether such results are observed in real-world population is unknown. In this hospital-based data, we report the survival outcomes of patients who received adjuvant radiation therapy versus those who did not...

BACKGROUND: Bile duct injury remains a dilemma in laparoscopic cholecystectomy, with an incidence still higher than in conventional cholecystectomy. The Critical View of Safety technique is used as one of the important operating technique to reduce bile duct injury incidence. The objective of this study was to determine current practices in laparoscopic cholecystectomy and the use of the Critical View of Safety technique among surgeons and residents in surgical training. METHODS: We conducted an electronic survey among all affiliated members of the Association of Surgeons of the Netherlands containing questions regarding the current practice of laparoscopic cholecystectomy, essential steps of the Critical View of Safety technique, reasons for conversion to open cholecystectomy, and the use of other safety techniques...

BACKGROUND: The accurate prediction of a pathologic complete response (ypT0N0M [LYM] 0 ypStage 0) before operation is essential for selecting appropriate strategies for treating esophageal cancer after neoadjuvant chemoradiotherapy. METHODS: We reviewed 130 consecutive patients with esophageal squamous cell carcinoma who were evaluated preoperatively using upper gastrointestinal endoscopy, computed tomography, and18 F-fluorodeoxyglucose-positron emission tomography after neoadjuvant chemoradiotherapy and subsequently underwent esophagectomy...

BACKGROUND: Critical illness including severe acute pancreatitis is associated with the multiple organ dysfunction syndrome. The "gut-lymph" hypothesis states that multiple organ dysfunction syndrome is due to release of toxic factors from the intestine into the mesenteric lymph. The aims of this study were to determine the effect of normotensive acute pancreatitis conditioned mesenteric lymph on cardiac function and whether external drainage of mesenteric lymph would protect the heart...

BACKGROUND: Acute calculous cholecystitis (ACC) is the most common complication of cholelithiasis. Laparoscopic cholecystectomy (LC) is the gold standard treatment in mild and moderate forms. Currently there is consensus for the use of antibiotics in the preoperative phase of ACC. However, the need for antibiotic therapy after surgery remains undefined with a low level of scientific evidence. METHODS: The CHART (Cholecystectomy Antibiotic Randomised Trial) study is a single-center, prospective, double blind, and randomized trial...

BACKGROUND: Portal vein embolization (PVE) use is nowadays debated due to the risk of technical or biological unresectability after the period of time needed to achieve future liver remnant (FLR) hypertrophy. We evaluated the safety and efficacy of PVE in a single high-volume hepatobiliary center, with emphasis in the feasibility to achieve tumor resection. METHODS: Patients undergoing PVE before major hepatectomy at our institution between 1993 and 2015 were retrospectively analyzed...

BACKGROUND: A postoperative water-forbidden strategy has been used for many decades. However, evidence shows that early contact with water postoperatively does not increase the infection rate. Our study evaluated the gap between currently available evidence and awareness in clinical practice of postoperative wound care. METHODS: We conducted a systematic review to compare the outcomes between postoperative water-contact and water-forbidden groups. PubMed, EMBASE, and Cochrane databases were searched...

BACKGROUND: The factors which affect hypertrophy of the future liver remnant after portal vein embolization remain unclear. The aim of this study was to clarify the clinical factors affecting the hypertrophy rate after portal vein embolization and to develop a scoring system predicting insufficient liver hypertrophy. METHODS: The cases of a total of 152 patients who underwent portal vein embolization of the right portal branch between 2006 and 2016 were reviewed retrospectively...

BACKGROUND: The number of patients in the United States (US) who speak a language other than English is increasing. We evaluated the impact of English proficiency on self-reported patient-provider communication and shared decision-making. METHODS: The 2013-2014 Medical Expenditure Panel Survey database was utilized to identify respondents who spoke a language other than English. Patient-provider communication (PPC) and shared decision-making (SDM) scores from 4-12 were categorized as "poor" (4-7), "average" (8-11), and "optimal...

BACKGROUND: The Accreditation Council for Graduate Medical Education mandates scheduled didactics for residency programs but allows flexibility in implementation. Work-hour restrictions, patient care duties, and operative schedules create barriers to attendance for surgical trainees. We explored vascular surgery trainees and faculty perceptions on trainees operative preparation and participation, and overall fund of knowledge after implementing an academic half day conference (AHD) schedule...

BACKGROUND: Resection of hepatocellular carcinoma located in the caudate lobe is challenging because this anatomical location is difficult to approach, especially the caval portion. METHODS: We performed resection of the caval portion of the caudate lobe using a ventral approach combined with the resection of segment IV, VII, or VIII for hepatocellular carcinoma in 41 patients (extended segmentectomy group). As a control group, 138 patients with hepatocellular carcinoma who underwent segmentectomy for IV, VII, or VIII (segmentectomy group) were studied...

BACKGROUND: Hepaticojejunostomy is commonly indicated for major bile duct injury after cholecystectomy. The debate about the timing of hepaticojejunostomy for bile duct injury persists since data on postoperative outcomes, including postoperative strictures, are lacking. The aim of this study was to analyze short- and long-term outcomes of hepaticojejunostomy for bile duct injury, including risk factors for strictures. METHOD: Analysis of outcome of hepaticojejunostomy in bile duct injury patients referred to a multidisciplinary team...

BACKGROUND: Hepatitis B virus X (HBx) protein plays critical roles in hepatitis B virus (HBV)-associated hepatocellular tumorigenesis through different molecular mechanisms, including inactivation of p53, a key transcription factor of liver kinase B1 (LKB1). We hypothesized that p53 inactivation by HBx protein could decrease LKB1 expression, thereby promoting tumor progression and poor outcomes in patients with HBV-associated hepatocellular carcinoma. METHODS: Manipulation strategies for HBx protein and/or p53 were used to verify that loss of LKB1 could promote colony formation and invasiveness in HepG2 and Hep3B cells...
