Akuutin haimatulehduksen diagnostiikka ja hoito

VertaisarvioituAkuutin haimatulehduksen yleisin aiheuttaja Suomessa liiallinen alkoholin käyttö. Vaikea tautimuoto on tärkeää tunnistaa nopeasti. Ensimmäisen vuorokauden maltillinen nesteytys Ringerin liuoksella ja elintoimintojen monitorointi parantavat ennustetta. Vatsaontelon painetta lasketaan konservatiivisen hoidon menetelmin. Myös varhainen enteraalinen ravitsemus on tärkeä. Pienellä osalla potilaista voidaan joutua kajoavaan hoitoon, ja siinä mini-invasiiviset menetelmät ovat ensisijaisia. Taudin uusiutumista estävät sappikivitaudin hoito ja alkoholin käytön lopettaminen.Peer reviewe

Endoskopia haimasairauksien diagnostiikassa

VertaisarvioituEndoskooppisia menetelmiä käytetään yhä enemmän kuvantamisen tukena epäselvien haimamuutosten selvittelyssä. Ensisijainen keino solu- tai kudosnäytteen saamiseksi haimamuutoksesta on neulanäytteen ottaminen kaikuendoskopiaohjauksessa. Haimatiehyen tähystystä voidaan käyttää valikoiduissa tapauksissa haimatieahtauman tai -laajentuman selvityksissä. Useimpien haimamuutosten hoitolinja voidaan päättää tietokonetomografian ja magneettikuvan perusteella. Endoskooppisia menetelmiä pitää käyttää valikoiden ja moniammatillisen harkinnan jälkeen.Peer reviewe

Macroscopic appearance of the major duodenal papilla influences bile duct cannulation : a prospective multicenter study by the Scandinavian Association for Digestive Endoscopy Study Group for ERCP

Background and Aims: Certain appearances of the major duodenal papilla have been claimed to make cannulation more difficult during ERCP. This study uses a validated classification of the endoscopic appearance of the major duodenal papilla to determine if certain types of papilla predispose to difficult cannulation. Methods: Patients with a naive papilla scheduled for ERCP were included. The papilla was classified into 1 of 4 papilla types before cannulation started. Time to successful bile duct cannulation, attempts, and number of pancreatic duct passages were recorded. Difficult cannulation was defined as after 5 minutes, 5 attempts, or 2 pancreatic guidewire passages. Results: A total of 1401 patients were included from 9 different centers in the Nordic countries. The overall frequency of difficult cannulation was 42% (95% confidence interval [CI], 39%-44%). Type 2 small papilla (52%; 95% CI, 45%-59%) and type 3 protruding or pendulous papilla (48%; 95% CI, 42%-53%) were more frequently difficult to cannulate compared with type 1 regular papilla (36%; 95% CI, 33%-40%; both P <.001). If an inexperienced endoscopist started cannulation, the frequency of failed cannulation increased from 1.9% to 6.3% (P <.0001), even though they were replaced by a senior endoscopist after 5 minutes. Conclusions: The endoscopic appearance of the major duodenal papilla influences bile duct cannulation. Small type 2 and protruding or pendulous type 3 papillae are more frequently difficult to cannulate. In addition, cannulation might even fail more frequently if a beginner starts cannulation. These findings should be taken into consideration when performing studies regarding bile duct cannulation and in training future generations of endoscopists.Peer reviewe

Practice patterns in diagnostics, staging, and management strategies of gallbladder cancer among Nordic tertiary centers

Background and objective: Gallbladder cancer (GBC) is a rare malignancy in the Nordic countries and no common Nordic treatment guidelines exist. This study aimed to characterize the current diagnostic and treatment strategies in the Nordic countries and disclose differences in these strategies. Methods: This was a survey study with a cross-sectional questionnaire of all 19 university hospitals providing curative-intent surgery for GBC in Sweden, Norway, Denmark, and Finland. Results: In all Nordic countries except Sweden, neoadjuvant/downstaging chemotherapy was used in GBC patients. In T1b and T2, majority of the centers (15–18/19) performed extended cholecystectomy. In T3, majority of the centers (13/19) performed cholecystectomy with resection of segments 4b and 5. In T4, majority of the centers (12–14/19) chose palliative/oncological care. The centers in Sweden extended lymphadenectomy beyond the hepatoduodenal ligament, whereas all other Nordic centers usually limited lymphadenectomy to the hepatoduodenal ligament. All Nordic centers except those in Norway used adjuvant chemotherapy routinely for GBC. There were no major differences between the Nordic centers in diagnostics and follow-up. Conclusions: The surgical and oncological treatment strategies of GBC vary considerably between the Nordic centers and countries.publishedVersio

Diagnosis, treatment and prophylaxis of pancreatic fistulas in severe necrotizing pancreatitis and the long-term outcome of acute pancreatitis

Abstract Acute infected necrotizing pancreatitis (ANP) is a very complex disease with a high risk of complications and death. ANP is difficult to treat and is often associated with poor outcomes. Despite the increasing data on the technical details required to perform a mini-invasive necrosectomy for walled-off necrosis (WON), relatively few studies have focused on the presence and consequences of pancreatic duct disruption in the context of APN. Moreover, the long-term prognosis of patients with acute pancreatitis (AP) is scant. The aim of this study was to examine the diagnosis, treatment and prophylaxis of pancreatic fistulas (PFs) associated with APN. In addition, the long-term prognosis of AP was evaluated. The study population consists of the patients with AP treated at Oulu University Hospital, Finland (Studies I–IV) and Copenhagen University Hospital, Denmark (Study II) during 1995–2015. In the first part of the study, all consecutive patients following open necrosectomy for infected ANP were demonstrated to have PF. Endoscopic transpapillary pancreatic stenting (ETPS) was attempted and proven to be an effective and safe treatment for patients with PF. In Study II, prophylactic pancreatic stenting in the early stage of the disease was tested in a randomized controlled trial to the patients with ANP to prevent PFs associated with the disease. However, the study showed that the patients with ANP did not benefit from early prophylactic pancreatic ductal stenting (PPDS); instead, it seemed to be harmful for the patients. The results of Study III showed that single drain amylase level measurement after surgical necrosectomy is unreliable. According to this study, serial measurements are recommended to diagnose PFs after necrosectomy. Study IV including 1644 patients showed that AP, especially alcohol AP, was associated with a high long-term mortality. On the other hand, AP without an alcohol aetiology had a minimal impact on survival. In conclusion, in patients with infected ANP, a PF has to be considered in treatment, but the prevention of ductal leak with PPDS is not recommended. In addition, the poor long-term outcome among alcohol AP patients was due to alcohol-related diseases.Tiivistelmä Akuutti nekrotisoiva haimatulehdus ja erityisesti siihen liittyvä bakteeri-infektio on sairaus, johon liittyy korkea komplikaatio- ja kuolleisuusriski. Tautia usein komplisoi infektion lisäksi nekroosiin liittyvä haimafisteli, joka tekee hoidosta entistä haasteellisemman. Viime aikaisissa tutkimuksissa on käsitelty runsaasti mini-invasiivista nekrosektomiaa, mutta suhteellisen vähän on tutkimuksia nekrotisoivaan haimatulehdukseen liittyvästä fisteliongelmasta. Haimatulehdus-potilaiden pitkäaikaisennuste on myös epäselvä. Tämän väitöskirjatutkimuksen tavoitteena oli selvittää nekrotisoivaan haimatulehdukseen liittyvän haimafistelin yleisyyttä, diagnostiikkaa, ehkäisyä ja hoitoa. Lisäksi tarkasteltiin akuuttiin haimatulehdukseen sairastuneiden potilaiden pitkäaikaisennustetta. Ensimmäisessä osatyössä ilmeni, että kaikille potilaille, joille suoritettiin haiman nekrosektomia kehittyi fisteli ja endoskooppinen transpapillaarinen haimateiden stenttaus (ETPS) osoittautui hyväksi ja turvalliseksi hoidoksi fistelin hoidossa. Toisessa prospektiivisessa randomoidussa kontrolloidussa osatyössä tutkittiin profylaktista haimateiden stenttausta nekrotisoivassa haimatulehduksessa. Tutkimus osoitti, etteivät potilaat hyötyneet stenttauksesta: toimenpiteestä oli enemmän haittaa kuin hyötyä. Tämän tutkimuksen mukaan protetisointia ei suositella tehtäväksi taudin alkuvaiheessa. Kolmannessa osatyössä selvitettiin haiman nekrosektomian jälkeisen haimafistelin diagnosointia. Tutkimustuloksen mukaan haimafistelin osoittamiseksi dreenieritteen amylaasitasoa mittaamalla tarvitaan useita mittauskertoja, koska yksittäisen mittauksen sensitiivisyys on matala. Neljännessä osatyössä analysoitiin Oulun yliopistollisessa sairaalassa 1995–2012 akuutin haimatulehduksen sairastaneiden työikäisten potilaiden pitkäaikaisennustetta ja kuolinsyitä. Noin kymmenen vuoden seurannassa tutkimusryhmän (n = 1 644) kuolleisuus oli yli nelinkertainen verrattuna ikä- ja sukupuolivakioituihin verrokeihin (n = 8 220). Merkittävin kuolleisuutta lisäävä tekijä oli alkoholi. Tutkimuksemme osoitti, että infektoituneen haimanekroosiin liittyvä haimafisteli on huomioitava hoidossa. Varhaisesta profylaktisesta haimateiden protetisoinnista ei tutkimuksessa osoitettu olevan hyötyä. Alkoholin aiheuttaman haimatulehduksen pitkäaikaisennusteen mortaliteetti on korkea johtuen alkoholin käytöstä ja siihen liittyvistä sairauksista

Evolution of pancreatic surgery over time and effects of centralization:a single-center retrospective cohort study

Abstract Background: Short-term outcomes of pancreatic surgery have improved globally during the last two decades. Long-term survival of resectable pancreatic ductal adenocarcinoma (PDAC) has also shown slight improvement. We describe a cohort of 566 consecutive pancreatectomies performed at a Northern Finnish tertiary center. We analyze the trends in short-term outcomes of all-cause pancreatic surgery and long-term survival of PDAC patients. Methods: All pancreatic resections performed at the Oulu University Hospital during years 2000–2020 were included. Patient data was analyzed in four time periods (2000–2005, 2006–2010, 2011–2015 and 2016–2020). Clinicopathological parameters of patients and tumors, complication data and short-term mortality were recorded for all patients and compared between time quartiles. Long-term survival and administration rates of neo-, and/or adjuvant therapy of PDAC patients were analyzed. Results: A total of 566 pancreatectomies were performed during the study period: 359 (63%) pancreatoduodenectomies (PDs), 130 (23.0%) open left pancreatectomies (LPs), 45 (8.0%) laparoscopic LPs, 26 (5.1%) total pancreatectomies (TPs), and 6 (1.1%) enucleations. Median age of patients was 63 [57–71] years, and 49% [267] of patients were men. Number of pancreatectomies per time period increased from 67 in 2000–2005 to 266 in 2016–2020. American Society of Anesthesiologists (ASA) Physical Classification III patients and T3 tumors were more frequently operated on in later time periods. Complication rates remained at constant low levels throughout the study period, but reoperation rate increased from 9.4% in 2000–2010 to 16.2% in 2011–2020. Short-term (90-day) mortality after pancreatectomy decreased from 3.1% to 0.74%, while 5-year survival improved from 14.3% in 2006–2011 to 21.4% in 2011–2015. Resection rate of diagnosed PDAC cases, as reported by the Finnish Cancer Registry (FCR) for the catchment area, increased from 3.2% to 14.9% over the study period. Conclusions: The hospital volume of pancreatectomies has increased substantially, while complications and postoperative mortality have remained at acceptable levels. Long-term survival and resection rate of PDAC patients showed notable improvement over two decades
