Stent treatment or surgical closure for perforated duodenal ulcers: a prospective randomized study.

BACKGROUND: Perforated peptic ulcer is a life-threatening condition. Traditional treatment is surgery. Esophageal perforations and anastomotic leakages can be treated with endoscopically placed covered stents and drainage. We have treated selected patients with a perforated duodenal ulcer with a partially covered stent. The aim of this study was to compare surgery with stent treatment for perforated duodenal ulcers in a multicenter randomized controlled trial. METHODS: All patients presenting at the ER with abdominal pain, clinical signs of an upper G-I perforation, and free air on CT were approached for inclusion and randomized between surgical closure and stent treatment. Age, ASA score, operation time, complications, and hospital stay were recorded. Laparoscopy was performed in all patients to establish diagnosis. Surgical closure was performed using open or laparoscopic techniques. For stent treatment, a per-operative gastroscopy was performed and a partially covered stent was placed through the scope. Abdominal lavage was performed in all patients, and a drain was placed. All patients received antibiotics and intravenous PPI. Stents were endoscopically removed after 2-3 weeks. Complications were recorded and classified according to Clavien-Dindo (C-D). RESULTS: 43 patients were included, 28 had a verified perforated duodenal ulcer, 15 were randomized to surgery, and 13 to stent. Median age was 77.5 years (23-91) with no difference between groups. ASA score was unevenly distributed between the groups (p = 0.069). Operation time was significantly shorter in the stent group, 68 min (48-107) versus 92 min (68-154) (p = 0.001). Stents were removed after a median of 21 days (11-37 days) without complications. Six patients in the surgical group had a complication and seven patients in the stent group (C-D 2-5) (n.s.). CONCLUSIONS: Stent treatment together with laparoscopic lavage and drainage offers a safe alternative to traditional surgical closure in perforated duodenal ulcer. A larger sample size would be necessary to show non-inferiority regarding stent treatment.

EUS-guided reverse bevel fine-needle biopsy sampling and open tip fine-needle aspiration in solid pancreatic lesions - a prospective, comparative study.

OBJECTIVES: Different diagnostic entities can present as solid pancreatic lesions (SPL). This study aimed to explore the utility of endoscopic ultrasound-guided reverse bevel fine-needle biopsy sampling (EUS-FNB) in SPLs. MATERIAL AND METHODS: In 2012-2015, consecutive patients with SPLs were prospectively included in a tertiary center setting and subjected to dual needle sampling with a 22 gauge reverse bevel biopsy needle and a conventional 25 gauge open tip aspiration needle (EUS-FNA). The outcome measures were the diagnostic accuracy of sampling, calculated for each modality separately and for the modalities combined (EUS-FNA + FNB), and the adverse event rate related to sampling. RESULTS: In 68 unique study subjects, the most common diagnostic entities were pancreatic neuroendocrine tumor, PNET, (34%), pancreatic ductal adenocarcinoma, PDAC, (32%), pancreatitis (15%) and metastasis (6%). The overall diagnostic accuracy of EUS-FNB was not significantly different from that of EUS-FNA, (69% vs. 78%, p = .31). EUS-FNA + FNB, compared with EUS-FNA alone, had a higher sensitivity for tumors other than PDAC (89% vs. 69%, p = .02) but not for PDACs (95% vs. 85%, p = .5). No adverse event was recorded after the study dual-needle sampling procedures. CONCLUSIONS: Endoscopic ultrasound-guided tissue acquisition performed with a 22 gauge reverse bevel biopsy needle is safe but not superior to conventional fine-needle aspiration performed with a 25 gauge open tip needle in diagnosing solid pancreatic lesions. However, the performance of both these modalities may facilitate the diagnostic work-up in selected patients, such as cases suspicious for pancreatic neuroendocrine tumors and metastases.

Minimal Excision and Primary Suture is a Cost-Efficient Definitive Treatment for Pilonidal Disease with Low Morbidity: A Population-Based Interventional and a Cross-Sectional Cohort Study.

BACKGROUND: Conventional treatment of pilonidal disease with wide excision is associated with high morbidity. We describe the short- and long-term results and the impact on the health care system of a simple operation performed in the office under local anaesthesia, consisting of minimal excision of pilonidal sinuses with primary suture-the modified Lord-Millar operation (mLM). METHODS: All patients operated with mLM from February 2008 till November 2012 were prospectively followed for recurrence by telephone interviews and examination of symptomatic patients till July 2015. The outcome is compared with that in all patients operated with conventional wide excision from January 2003 till February 2008. The effects on the health care system of a consistent use of mLM is analysed by comparing the management of all patients with pilonidal disease at three hospitals during 2013 and 2014. RESULTS: Some 129 patients underwent conventional surgical treatment, and 113 had the mLM operation. The mLM operation was more often performed under local anaesthesia, was less often admitted to hospital, had fewer post-operative health care visits (2.4 vs. 14.6, p < 0.001) and a shorter sick leave (1.0 vs. 34.7 days, p < 0.001) indicating faster wound healing. The estimated 5-year recurrence rate was similar (32 vs. 23%, p = 0.091). The cost per operated patient was lower (2231 vs. 6222 EUR, p < 0.001). The hospital consistently applying the mLM operation used less resources for pilonidal diseased patients (34,545 vs. 77,421 EUR per 100,000 inhabitants and year). CONCLUSIONS: The mLM operation is simple, cost-efficient and has low morbidity and good long-term results.

Equivalent efficacy and safety of plastic stents and lumen-apposing metal stents in the treatment of peripancreatic fluid collections: a prospective cohort study.

Background: Endoscopic ultrasound (EUS)-guided transmural drainage using double pigtail plastic stents (DPPS) has been routine for the treatment of peripancreatic fluid collections (PFC). Lumen-apposing metal stents (LAMS) have since their introduction been the preferred choice; however, their superiority has not been proven. The aim of this study was to compare the efficacy and safety of DPPS and LAMS. Methods: This was a single-center, prospective study that included consecutive patients undergoing EUS-guided drainage between January 2010 and December 2020. The primary endpoints were technical success, clinical success and adverse event rate, while the secondary endpoints included symptomatic relief, length of hospital stay, and need for adjunct drainage. A subgroup analysis of walled-off necrosis (WON) was performed. Results: A total of 89 patients (median age 56 years) underwent EUS-guided transmural drainage (DPPS: n=53; LAMS: n=36) because of a pseudocyst (n=37) or a WON (n=52). Both DPPS and LAMS had a 100% technical success rate and a comparable adverse event rate (4% vs. 6%, P=0.24). An equivalent efficacy was recorded for the drainage of PFC comparing DPPS and LAMS, and no significant statistical difference was recorded in clinical success (DPPS 60% vs. LAMS 61%, P=0.94) or the need for reintervention (DPPS 11% vs. LAMS 13%, P=0.72). Conclusions: In this large, prospective study of EUS-guided drainage of peripancreatic fluid collections, LAMS and DPPS showed equivalent safety, technical success, clinical success and hospital stay. Both techniques were associated with a comparable need for complementary necrosectomy.

Impact of the COVID-19 pandemic on the management of gallstone surgery: A Swedish population-based study.

BACKGROUND: The SARS-CoV-2 pandemic has had a significant impact on healthcare delivery. As resources are reallocated, surgery for benign conditions such as gallstone disease is often given low priority. We do not know how this has affected the risk of patients with uncomplicated gallstone disease to develop acute cholecystitis, biliary pancreatitis, or obstructive jaundice. METHODS: The study was based on the population-based Swedish Register of Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography. The period prior to the first cases of COVID-19 in Sweden, that is, April 2015-March 2020, was compared to the period April 2020-March 2021 during the pandemic. Stratification was made for factors potentially related to priority decisions. RESULTS: Altogether, 78,211 procedures were performed during the period of the study. The ratio of procedures performed during April 2020-March 2021 in the previous 5 years was 0.960 (p = 0.113). The ratio of procedures on patients aged <65 years was 0.945 (p = 0.008), on patients aged 65-80 years was 0.964 (p = 0.423), on patients aged >80 years was 1.336 (p = 0.025), on men was 1.001 (p = 0.841), on women was 0.934 (p = 0.006), on procedures completed laparoscopically was 0.964 (p = 0.190), on procedures completed with open approach was 0.659 (p = 0.044), on acute procedures was 1.218 (p = 0.016), on planned procedures was 0.791 (p < 0.001), on procedures performed for biliary colic was 0.808 (p < 0.001), on procedures performed for acute cholecystitis was 1.274 (p = 0.012), for biliary pancreatitis was 1.192 (p = 0.037), and for obstructive jaundice was 1.366 (p = 0.008). CONCLUSIONS: The COVID-19 has had a great impact on how gallstone surgery has been organized over the last 2 years. The decreased number of planned procedures probably reflects the reallocation of resources during the pandemic. However, whether the increasing number of acute procedures is the result of postponed planned surgery or a continuation of a long-term trend toward more acute surgery remains unanswered. Further studies are needed to assess and evaluate how this has affected public health and health economics.

Preoperative Biliary Drainage Does Not Independently Reduce Survival After Pancreaticoduodenectomy Among Patients With Pancreatic Ductal Adenocarcinoma: A National Registry Study.

Objective: This study aimed to explore a possible relationship between preoperative biliary drainage (PBD) and overall survival in a national cohort of Swedish patients who underwent pancreaticoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC). Background: PBD has been shown to increase postoperative complications after PD, but its use is steadily increasing. There are a few small studies that have indicated that PBD might in itself negatively affect overall survival after PD. Methods: Patients from the Swedish National Registry for tumors in the pancreatic and periampullary region diagnosed from 2010 to 2019 who underwent PD for PDAC were included. Kaplan-Meier curves, log-rank tests and Cox proportional hazards analyses were performed to investigate survival. Results: Out of 15,818 patients in the registry, 3113 had undergone PD, of whom 1471 had a histopathological diagnosis of PDAC. Patients who had undergone PBD had significantly worse survival, but the effect of PBD disappeared in the multivariable analysis when elevated bilirubin at any time was included. Conclusions: PBD does not independently influence survival after PD for PDAC, but this study implies that even a nominally increased preoperative bilirubin level might impair long-term survival.
