ABSTRACT

Only a few decades ago, the opinion that colorectal liver metastases were a palliative diagnosis changed. In fact, previously, the prevailing view was strongly resistant against resecting colorectal liver metastases. Constant technical improvement of liver surgery and, much later, effective chemotherapy allowed for a successful wider application of surgery. The clinical use of portal vein embolization was the starting signal of regenerative liver surgery, where insufficient liver volume can be expanded to an extent where safe resection is possible. Today, a number of these techniques including portal vein ligation, associating liver partition and portal vein ligation for staged hepatectomy, and bi-embolization (portal and hepatic vein) can be successfully used to address an insufficient future liver remnant in staged resections. It turned out that the road to success is embedding surgery in a well-orchestrated oncological concept of controlling systemic disease. This concept was the prerequisite that meant liver transplantation could enter the treatment strategy for colorectal liver metastases, ending up with a 5-year overall survival of 80% in highly selected cases. In particular, techniques combining principles of 2-stage hepatectomy and liver transplantation, such as "resection and partial liver segment 2-3 transplantation with delayed total hepatectomy" (RAPID) are on the rise. These techniques enable the use of partial liver grafts with primarily insufficient liver volume. All this progress also prompted a number of innovative local therapies to address recurrences ultimately transferring colorectal liver metastases from instantly deadly into a chronic disease in some cases.

ABSTRACT

BACKGROUND: Patent ductus arteriosus (PDA) is frequently encountered in premature infants. Optimal management of PDA remains undefined. We aim to assess the national trend for PDA ligation over 18 years and evaluate mortality and associated morbidities. METHODS: We used data from the National Inpatient Sample (NIS) and KID of the Healthcare Cost and Utilization Project (HCUP) from 1998 to 2015. All infants with gestational age 24-32 weeks and birth weight <1500 g were included. Patients with PDA were classified into two groups: those who did and did not receive surgical ligation. Associated mortality and morbidities were compared. RESULTS: A total of 429,900 neonatal admissions were identified. Of them, 149,473 (34.8%) infants had PDA. PDA-ligated infants were 27,364 (6.4%). PDA ligation was more likely in those with smaller gestational age and with birth weight <1000 g. A steady decline in PDA ligation was noticed since 2004. The mortality rate in PDA-ligated infants was less than in PDA-non-ligated infants (7.5% vs. 8.9%; OR = 0.82; 95% CI: 0.78-0.86; p < 0.001). However, the prevalence rates of pulmonary hemorrhage and necrotizing enterocolitis (NEC) were greater in PDA-ligated infants (OR = 1.58; 95% CI: 1.49-1.67; p < 0.001, and OR = 1.32; 95% CI: 1.26-1.38; p < 0.001, respectively). CONCLUSIONS: Ligation of PDA has been steadily declining since 2004. Despite higher morbidities, PDA-ligated infants had less mortality.

ABSTRACT

BACKGROUND: Despite ongoing debates, there is still no consensus regarding where to divide the inferior mesenteric artery for oncological reasons in rectal cancer: at its origin from the aorta (high ligation) or distal to the origin of the left colic artery (low ligation). OBJECTIVES: The purpose of this study was to compare the outcomes of high and low ligation of the inferior mesenteric artery in rectal cancer surgery. DATA SOURCES: MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, World Health Organization International Clinical Trials Registry, ClinicalTrials.gov, and ISRCTN Register were searched. STUDY SELECTION: andomized controlled trials investigating outcomes of curative anterior resection in patients with cancer of the rectum were included. INTERVENTIONS: High ligation of the inferior mesenteric artery was compared with low ligation technique. MAIN OUTCOME MEASURES: We measured the total number of lymph nodes harvested, anastomotic leak, postoperative complications, postoperative mortality, operative time, intraoperative blood loss, conversion to open surgery, overall survival, and disease-free survival. RESULTS: Analysis of 1102 patients from 8 trials suggested no difference between high and low ligation of the inferior mesenteric artery in terms of total number of lymph nodes harvested (mean difference = -0.87; p = 0.26), anastomotic leak (OR = 1.39; p = 0.15), postoperative complications (OR = 1.39; p = 0.78), postoperative mortality (risk difference = -0.00; p = 0.48), operative time (mean difference = -1.99; p = 0.79), intraoperative blood loss (mean difference = -2.28; p = 0.77), conversion to open surgery (risk difference = 0.01; p = 0.48), 5-year overall survival (OR = 0.76; p = 0.32), 5-year disease-free survival (OR = 0.88; p = 0.58), overall survival at maximum follow up (OR = 0.80; p = 0.43), and disease-free survival at maximum follow-up (OR = 0.83; p = 0.35). LIMITATIONS: Limited data were available on functional and long-term survival outcomes. CONCLUSIONS: There is no difference between high and low ligation of the inferior mesenteric artery in terms of oncological outcomes or postoperative morbidity and mortality. The available evidence is subject to potential confounding by the use of neoadjuvant therapy, adjuvant therapy, disease stage, location of tumor, and use of protective stoma. Functional outcomes including postoperative bowel, urinary and sexual function, and long-term survival outcomes should be the outcome of study in future trials.

ABSTRACT

BACKGROUND: Distal pancreatectomy (DP) is performed to treat tumors of the pancreatic body and tail. Traditionally, splenectomy is performed with a DP, however, laparoscopic spleen-preserving DP (SPDP) using Warshaw's (splenic vessels ligation) or Kimura's (splenic vessels preservation) techniques have been reported. The clinical benefits of using either technique remain unclear. In this study, we conducted a meta-analysis to compare the clinical outcomes of patients undergoing Warshaw's and Kimura SPDP. This is the first study to evaluate the geographical variation in outcomes of Warshaw's and Kimura SPDP. METHODS: Databases of PubMed, Embase, and Cochrane library were used to identify studies reporting Warshaw's and Kimura SPDP. Clinical outcomes were compared. Pooled odds risk and weighted mean difference with 95% confidence interval were calculated using random effect models. RESULTS: Fourteen non-randomized controlled studies involving 945 patients met our selection criteria. 301 (31.9%) patients underwent Warshaw's SPDP; 644 (68.1%) underwent Kimura SPDP. Compared to Warshaw's SPDP, patients undergoing Kimura SPDP had a lower incidence of post-operative complications including spleen infarction (OR = 9.64, 95% CI = 5.79 to 16.05, P < 0.001) and gastric varices (OR = 11.88, 95% CI = 5.11 to 27.66, P < 0.001). The length of surgery was significantly shorter for Warshaw's SPDP (WMD = -18.12, 95%CI = -26.52 to -9.72, p < 0.001). Decreased blood loss was reported for patients undergoing Warshaw's SPDP (WMD = -59.72, 95%CI = -102.01 to -17.43, p = 0.006). There were no differences between the two groups' rates of conversion to an open procedure (P = 0.35), postoperative pancreatic fistula (P = 0.71), need for reoperation (P = 0.25), and length of hospital stay (P = 0.38). CONCLUSION: Both Warshaw's and Kimura are safe SPDP techniques. These data suggest Kimura SPDP is the preferred technique due to less risk of splenic infarct and gastric varices. Despite evidence of regional variation in volume performed (between Kimura and Warshaw's), there are no statistically significant differences in outcomes between these techniques.

ABSTRACT

Objective To assess trends in patent ductus arteriosus (PDA) management and examine concurrent changes in neonatal mortality and morbidities. Methods This retrospective observational study examined infants born at 23 to 32 weeks' gestational age with PDA and admitted to a neonatal unit during 2006 to 2012. Multivariable logistic regression assessed trends in yearly PDA treatment rates and compared a composite outcome of mortality or any severe morbidity (bronchopulmonary dysplasia, intraventricular hemorrhage, periventricular leukomalacia, retinopathy of prematurity, or necrotizing enterocolitis) between and within time periods and PDA treatments. Results Study subjects included 5,824 preterm neonates with clinical/echocardiographic PDA diagnosis. During 2006 to 2012, conservative management increased (14-38%), whereas pharmacotherapy-only (58-49%), surgical ligation-only (7.1-2.5%), and both pharmacotherapy and surgical ligation (21-10%) decreased (p-values <0.01). From 2006 to 2008 and 2009 to 2012, the composite outcome decreased for infants managed conservatively (AOR = 0.70, 95% CI 0.52-0.92), with no changes detected for pharmacotherapy and/or ligation. Lower composite outcome after conservative management versus pharmacotherapy-only during 2009 to 2012 (AOR = 0.61, 95% CI 0.51-0.74), but not during 2006 to 2008 reflect significant effect modification by time period. Conclusion In Canada, during 2006 to 2012, conservative PDA management increased while pharmacotherapy and/or surgical ligation decreased. Lower composite outcome was detected during later years after increases in conservative management; however, bias due to unmeasured confounders remains possible.

ABSTRACT

OBJECTIVE: We sought to analyse the variation in the incidence of patent ductus arteriosus over three recent time points and characterise ductal ligation practices in preterm infants in the United States, adjusting for demographic and morbidity factors. METHODS: Using the Kids' Inpatient Database from 2003, 2006, and 2009, we identified infants born at ⩽32 weeks of gestation with International Classification of Diseases, Ninth Revision diagnosis of patent ductus arteriosus and ligation code. We examined patient and hospital characteristics and identified patient and hospital variables associated with ligation. RESULTS: Of 182,610 preterm births, 30,714 discharges included a patent ductus arteriosus diagnosis. The rate of patent ductus arteriosus diagnosis increased from 14% in 2003 to 21% in 2009 (p<0.001). A total of 4181 ligations were performed, with an overall ligation rate of 14%. Ligation rate in infants born at ⩽28 weeks of gestation was 20% overall, increasing from 18% in 2003 to 21% in 2009 (p<0.001). The ligation rate varied by state (4-28%), and ligation was associated with earlier gestational age, associated diagnoses, hospital type, teaching hospital status, and region (p<0.001). CONCLUSION: The rates of patent ductus arteriosus diagnosis and ligation have increased in the recent years. Variation exists in the practice of patent ductus arteriosus ligation and is influenced by patient and non-patient factors.

ABSTRACT

PURPOSE: The transanal hemorrhoidal de-arterialization (THD) procedure is an effective treatment of hemorrhoidal disease. The ligation of hemorrhoidal arteries ("de-arterialization") can provide a significant reduction of arterial blood flow to the hemorrhoidal tissues. Plication of redundant rectal mucosa/submucosa ("mucopexy") can reposition prolapsing tissue to its original anatomical site. In this paper the surgical technique using a specific device (THD(®) Doppler) and peri-operative patient management are illustrated. METHODS: After appropriate clinical assessment, patients undergo the THD procedure under general or spinal anesthesia, in either the dorsal lithotomy or prone jackknife position. A specifically designed device is used. In all patients, THD is performed, consisting of selective ligation of hemorrhoidal arteries identified by Doppler and marked with a mucosal stitch overlying the artery. In patients with hemorrhoidal or mucosal prolapse, a mucopexy is also performed using continuous suture(s) that include the redundant prolapsing mucosa and submucosa. RESULTS: In long-term follow-up, THD results in resolution of symptoms in the majority of patients. The most common complication is transient but sometimes-painful tenesmus. Rectal bleeding occurs in only a very limited number of patients. There is little or no risk of fecal incontinence or chronic pain. Ano-rectal manometry and endo-anal ultrasound show no evidence of injury to physiologic sphincteric function. CONCLUSIONS: THD is a safe procedure and is, at present, one of the most effective treatments of hemorrhoidal disease.

ABSTRACT

ANTECEDENTES: La insuficiencia hepática postresección es una de las principales causas de muerte en el postoperatorio de una hepatectomía mayor. La técnica ALPPS aparece como una estrategia prometedora para evitarla, pero no existen estudios experimentales al respecto. El objetivo del trabajo es desarrollar un modelo experimental de ALPPS en ratas. MÉTODO: Se desarrolló un modelo experimental de ALPPS en 30 ratas Sprague Dawley. Se realizó la ligadura de la rama portal izquierda del lóbulo medio (LM), con lo cual se demarca el sector izquierdo (SILM) y derecho (SDLM); posteriormente se realizó la transección parenquimatosa por la línea isquémica. Se evaluaron el peso del animal, el volumen y peso del LM y de ambos. Sacrificio a los 3, 7 y 14 días (10 por grupo). RESULTADOS: No se presentaron complicaciones hemorrágicas ni ascitis en el postoperatorio. El incremento del volumen del LM fue del 24,1; 86,9 y 120,4% a los 3, 7 y 14 días. El SDLM (no ligado) se incrementó un 34,4; 78,8 y 102,0% a 3, 7 y 14 días. El SILM disminuyó un 42,6; 64,8, y 79,3% en los días 3, 7 y 14. CONCLUSIÓN: La realización del ALPPS fue posible en ratas, logrando los resultados esperados. Futuros estudios son necesarios para compararlo con la técnica de hepatectomía en 2 tiempos


BACKGROUND: Liver failure migth be a cause of death after major hepatectomies. The ALPPS technique appears to be a promising strategy to avoid it, however no experimental studies supporting this procedure have been previously described. The aim was to develop an experimental model of ALPPS in rats. Method. Experimental. A total of 30 Sprague Dawley rats were used. To develop the ALPPS procedure, ligation of the left portal branch of the middle lobe (LM) was performed. This demarcates the left side (SILM) from the right side (SDLM); parenchyma transection was performed following the demarcated line. The animal's weight, volume and weight of both LM were analyzed. Sacrifice at 3, 7 and 14 days after the procedure (10 per group) was performed. RESULTS: No bleeding or ascites were observed during the postoperative period. The LM increased by 24.1, 86.9 and 120.4% at 3, 7 and 14 days. The SDLM increased by 34.4, 78.8 and 102.0% at 3, 7 and 14 days. The SILM decreased 42.6, 64.8, and 79.3% at day 3, 7 and 14 days respectively. CONCLUSION: The ALPPS procedure can be performed in rats, achieving the expected results. Comparison studies to 2 staged hepatectomy will be necessary

ABSTRACT

IMPORTANCE: The treatment of epistaxis is variable. It is important to analyze the effect of the available interventions on patient outcomes. OBJECTIVE: To determine demographic, management, and outcome trends in patients admitted with a primary diagnosis of epistaxis and treated with conservative management, nasal packing, arterial ligation, or embolization. DESIGN, SETTING, AND PARTICIPANTS: A review of the data reported by hospitals to the 2008-2010 Nationwide Inpatient Sample for patients admitted with a primary diagnosis of epistaxis was conducted. INTERVENTIONS: Conservative management, nasal packing, arterial ligation, or embolization for epistaxis control. MAIN OUTCOMES AND MEASURES: Descriptive statistics for hospital and patient demographic data. Multivariate models were constructed to compare treatment modalities, controlling for patient- and hospital-level variation while reporting the treatment outcomes of mortality, stroke, blindness, length of stay, and total cost. Comparisons were made between patients undergoing embolization, surgical ligation, or nasal packing. Descriptive statistics for patients treated conservatively are reported. RESULTS: A total of 57, 039 cases of primary epistaxis were identified. Of these, 21, 872 patients (38.3%) were treated conservatively, 30, 389 (53.3%) received nasal packing or cauterization, 2706 (4.7%) underwent arterial ligation, and 1956 (3.4%) underwent embolization The odds of stroke in patients following embolization were significantly higher than in patients who underwent nasal packing (odds ratio, 4.660; P = .003), with no significant difference seen compared with surgical ligation (P = .70). There were no significant differences in the odds of mortality or blindness between any of the study groups. Patients undergoing embolization incurred the highest total hospital costs, nearly doubling the cost of ligation (P < .001), without a corresponding increase in the length of hospital stay (P = .20). CONCLUSIONS AND RELEVANCE: Treatment for epistaxis is highly variable. No significant differences in clinical outcomes were noted between arterial ligation and embolization in the population studied, although embolization resulted in significantly higher costs. Further prospective studies are needed to elucidate variables affecting outcomes of the various treatment options for epistaxis.

ABSTRACT

BACKGROUND: There is little consensus over the optimal timing of ligation of a patent processus vaginalis (PPV) in boys with hydrocele. We hypothesized that a proportion of procedures may be unnecessary because they are performed at an age before which the PPV may be expected to close spontaneously. Such excess may expose the child to unnecessary surgery and have significant cost implications. METHODS: A systematic literature review relating to timing of PPV ligation and a population-based study to define number of PPV ligations performed annually in England and age at surgery were conducted. RESULTS: Most hydroceles resolve before 2 years of age, but their natural history beyond this age is poorly documented. Current guidelines recommend PPV ligation at 2 years of age. An average of 2878 operations for hydrocele is performed per year in children in England. Commonest age at repair is 2 years. There are no randomized controlled trials comparing PPV ligation with an observational nonoperative approach. CONCLUSIONS: The natural history of hydrocele is poorly documented beyond the age of 2 years. There is no good evidence to support current practice. Delaying surgery may reduce the number of procedures necessary without increasing morbidity. A prospective study to investigate this is warranted.

ABSTRACT

Bleeding from esophageal varices (EVs) is a catastrophic complication of chronic liver disease. Many years ago, surgical procedures such as esophageal transection or distal splenorenal shunting were the only treatments for EVs. In the 1970s, interventional radiology procedures such as transportal obliteration, left gastric artery embolization, and partial splenic artery embolization were introduced, improving the survival of patients with bleeding EVs. In the 1980s, endoscopic treatment, endoscopic injection sclerotherapy (EIS), and endoscopic variceal ligation (EVL), further contributed to improved survival. We combined IVR with endoscopic treatment or EIS with EVL. Most patients with EVs treated endoscopically required follow-up treatment for recurrent varices. Proper management of recurrent EVs can significantly improve patients' quality of life. Recently, we have performed EVL at 2-mo (bi-monthly) intervals for the management of EVs. Longer intervals between treatment sessions resulted in a higher rate of total eradication and lower rates of recurrence and additional treatment.

ABSTRACT

In Germany almost every third adult suffers from varicose veins requiring treatment. Conventional varicose vein surgery by high ligation and stripping is widely accepted as standard therapy for saphenous vein insufficiency, although associated with a high frequency of recurrent varicosities. Innovative endovascular procedures laying claim to be minimally invasive have been implemented over the last five years: endovenous radiofrequency obliteration, endovenous laser treatment and ultrasound-guided sclerotherapy with foam. The early treatment outcomes are promising in regard to recurrent varicose veins, cosmetic results and convalescence. Evidence-based prospective trials with large numbers of participants comparing the interventional procedures with high ligation and stripping are still missing. This report delineates current developments in varicose vein surgery and provides information on principles, effectiveness and side effect profiles of endovascular therapy procedures.
