Beger’s operation and the Berne modification: origin and current results
Tập 17 - Trang 735-744 - 2009
The purpose of this paper is to illuminate the origin and current results of the duodenum-preserving pancreatic head resection (DPPHR) developed by Beger in the 1970s, as well as its simplified Berne modification, for patients suffering from chronic pancreatitis (CP). Indications for the procedures and their results are presented on the basis of available data. A selected review was made of the available data on the DPPHR developed by Beger and its modifications. The organ-sparing DPPHR developed by Beger, and its modifications, provide better pain relief, better preservation of exocrine and endocrine pancreatic function, and a superior quality of life compared with the more radical pancreaticoduodenectomy (PD, with or without pylorus-preservation), once the standard treatment for patients with CP. Recently published data on the long-term follow-up of studies comparing PD to DPPHR indicate that the initial benefits of DPPHR over PD might be less pronounced in the long-run. The organ-preserving DPPHR developed by Beger, and its modifications, have become established and well-evaluated surgical treatment options for patients with CP.
Tokyo Guidelines 2018: initial management of acute biliary infection and flowchart for acute cholangitis Abstract The initial management of patients with suspected acute biliary infection starts with the measurement of vital signs to assess whether or not the situation is urgent. If the case is judged to be urgent, initial medical treatment should be started immediately including respiratory/circulatory management if required, without waiting for a definitive diagnosis. The patient's medical history is then taken; an abdominal examination is performed; blood tests, urinalysis, and diagnostic imaging are carried out; and a diagnosis is made using the diagnostic criteria for cholangitis/cholecystitis. Once the diagnosis has been confirmed, initial medical treatment should be started immediately, severity should be assessed according to the severity grading criteria for acute cholangitis/cholecystitis, and the patient's general status should be evaluated. For mild acute cholangitis, in most cases initial treatment including antibiotics is sufficient, and most patients do not require biliary drainage. However, biliary drainage should be considered if a patient does not respond to initial treatment. For moderate acute cholangitis, early endoscopic or percutaneous transhepatic biliary drainage is indicated. If the underlying etiology requires treatment, this should be provided after the patient's general condition has improved; endoscopic sphincterotomy and subsequent choledocholithotomy may be performed together with biliary drainage. For severe acute cholangitis, appropriate respiratory/circulatory management is required. Biliary drainage should be performed as soon as possible after the patient's general condition has been improved by initial treatment and respiratory/circulatory management.

Molecular pathogenesis of intrahepatic cholangiocarcinoma Abstract Cholangiocarcinoma (CCA ) is an orphan cancer of the hepatobiliary tract, the incidence of which has increased in the past decade. The molecular pathogenesis of this treatment‐refractory disease is poorly understood. Desmoplasia is a key causal feature of CCA; however, a majority of tumors develop with no apparent etiological background. The impact of the stromal compartment on tumor progression as well as resistance to therapy is in vogue, and the epithelial‐stromal crosstalk may present a target for novel treatment strategies. As such, the complexity of tumor cellularity and the molecular mechanisms underlying the diversity of growth patterns of this malignancy remain a clinical concern. It is crucial to advance our present understanding of the molecular pathogenesis of CCA to improve current clinical strategies and patient outcome. This will facilitate the delineation of patient subsets and individualization for precision therapies. Many questions persevere as to the evolutionary process and cellular origin of the initial transforming event, the context of intratumoral plasticity and the causal driver action. Next‐generation sequencing has begun to underline the persistent alterations, which may be the trigger of acquired drug resistance, and the cause of metastasis and disease recurrence. A complex issue that remains is to account for the heterogeneous pool of “backseat” aberrations, which in chromosomal proximity to the causative variant are likely to influence, for example, drug response. This review explores the recent advances in defining the molecular pathways implicated in the development of this devastating disease and, which present putative clinical strategies.

The risk of spontaneous rupture of liver hemangiomas: a critical review of the literature
Tập 18 - Trang 797-805 - 2011
The risk of spontaneous bleeding or rupture of liver hemangiomas still remains unknown. The aim of this review was to analyze the problem of spontaneous bleeding or rupture in liver hemangiomas and to identify factors leading to bleeding in these cases. A MEDLINE search was undertaken to identify articles in English, French, German, Italian, and Spanish from 1898 to 2010. Basic data such as age and sex of patients were collected. Additional data such as risk factors or causes of rupture were also analyzed. Cases were divided into spontaneous and non-spontaneous ruptures. A total of 97 cases are described. In 51 of the 97 patients (52.6%) a non-spontaneous rupture was identified. Only in 46 out of the 97 cases (47.4%) was a spontaneous rupture found. Non-spontaneous rupture was significantly more frequent in patients aged <40 years than in older ones (p = 0.0099). Mean size of the ruptured lesions was 11.2 cm (range 1–37 cm). Massive bleeding occurred in 88 patients (90.7%). Reported mortality over the past 20 years has been significantly lower than before (p < 0.001). The overall mortality for the period under study was ~35%. The spontaneous rupture of a hepatic hemangioma is to be considered an exceptional event. Preventive surgery should be considered only for lesions of at least 11-cm size in special cohorts of patients.
How to expand the safe limits in hepatic resections? Abstract The size of the remnant liver after an extended hepatectomy is currently the main limiting factor for performing curative hepatic surgery in patients with tumors and liver metastasis. The current guidelines for extended hepatectomies require that the future remnant liver volume needs to be higher than 20% of the original liver in healthy organs, of 30% in livers with steatosis or exposed to chemotherapy, and of 40% in patients with cirrhosis in order to prevent the “small‐for‐size” syndrome, characterized by the development of liver dysfunction with ascites, coagulopathy and cholestasis. Observations from the use of small liver grafts in liver transplantation and an increased surgical experience has improved our understanding of the mechanisms responsible for the development of liver dysfunction after extended hepatectomies. Increasing the size of the future liver remnant, the introduction of the “small‐for‐flow” concept with the perioperative monitoring and modulation of portal blood flow and pressure, and the exploration of the potential effects of regeneration preconditioning, are all promising strategies that could expand the indications and increase the safety of liver surgery.

Tokyo Guidelines 2018: surgical management of acute cholecystitis: safe steps in laparoscopic cholecystectomy for acute cholecystitis (with videos) Abstract In some cases, laparoscopic cholecystectomy (LC) may be difficult to perform in patients with acute cholecystitis (AC) with severe inflammation and fibrosis. The Tokyo Guidelines 2018 (TG18) expand the indications for LC under difficult conditions for each level of severity of AC. As a result of expanding the indications for LC to treat AC, it is absolutely necessary to avoid any increase in bile duct injury (BDI), particularly vasculo‐biliary injury (VBI), which is known to occur at a certain rate in LC. Since the Tokyo Guidelines 2013 (TG13), an attempt has been made to assess intraoperative findings as objective indicators of surgical difficulty; based on expert consensus on these difficulty indicators, bail‐out procedures (including conversion to open cholecystectomy) have been indicated for cases in which LC for AC is difficult to perform. A bail‐out procedure should be chosen if, when the Calot's triangle is appropriately retracted and used as a landmark, a critical view of safety (CVS) cannot be achieved because of the presence of nondissectable scarring or severe fibrosis. We propose standardized safe steps for LC to treat AC. To achieve a CVS, it is vital to dissect at a location above (on the ventral side of) the imaginary line connecting the base of the left medial section (Segment 4) and the roof of Rouvière's sulcus and to fulfill the three criteria of CVS before dividing any structures. Achieving a CVS prevents the misidentification of the cystic duct and the common bile duct, which are most commonly confused.

A three‐step conceptual roadmap for avoiding bile duct injury in laparoscopic cholecystectomy: an invited perspective review Abstract Bile duct injuries are the most common serious complication of cholecystectomy. Avoidance of bile duct injury is a key aim of biliary surgery. The purpose of this paper is to describe laparoscopic cholecystectomy from the viewpoint of three conceptual goals. Three conceptual goals of cholecystectomy are: (1) getting secure anatomical identification of key structures; (2) making the right decision not to perform a total cholecystectomy when conditions are too dangerous to get secure identification – the “inflection point”; and (3) finishing the operation safely when secure anatomical identification of cystic structures is not possible. The Critical View of Safety (CVS) has been shown to be a good way of getting secure anatomical identification. Conceptually, CVS is a method of target identification, the targets being the two cystic structures. Sometimes, anatomic identification is not possible because the risk of biliary injury is judged to be too great. Then a decision is made to abandon the attempt to do a complete cholecystectomy – and instead to “bail‐out”. This “inflection point” is defined as the moment at which the decision is made to halt the attempt to perform a total cholecystectomy laparoscopically and to finish the operation by a different method. Currently the best bail‐out procedure seems to be subtotal fenestrating cholecystectomy. Application of conceptual goals of cholecystectomy can help the surgeon to avoid biliary injury.
