Background: Conservative treatment of chronic pancreatitis has only a limited effect in most patients. Surgery offers very good long-term results, even in the early stages of the disease. Unfortunately, only a minority of patients undergo surgical treatment. The aim of this work was to summarise the current treatment options for patients with an inflammatory mass of the pancreatic head. Data from patients in our study demonstrates that the surgery is a safe method, and here we compare the perioperative and early postoperative outcomes of patients who underwent a pancreatoduodenectomy and duodenum-preserving pancreatic head resection for chronic pancreatitis., Methods: All patients who underwent a pancreaticoduodenectomy or a duodenum-preserving pancreatic head resection in our department between 2014 and 2022 were included in this study. Perioperative and early postoperative results were statistically analysed and compared., Results: Thirty-eight pancreaticoduodenectomies and 23 duodenum-preserving pancreatic head resections were performed. The overall mortality was 3%, whereas the in-hospital mortality after pancreaticoduodenectomy was 5%. The mortality after duodenum-preserving pancreatic head resection was 0%. No statistically significant differences in the hospital stay, blood loss, and serious morbidity were found in either surgery. Operative time was significantly shorter in the duodenum-preserving pancreatic head resection group., Conclusions: Both pancreatoduodenectomy and duodenum-preserving pancreatic head resection are safe treatment options. Duodenum-preserving pancreatic head resection showed a statistically significant superiority in the operative time compared to pancreaticoduodenectomy. Although other monitored parameters did not show a statistically significant difference, the high risk of complications after pancreaticoduodenectomy with a mortality of 5%; maintenance of the duodenum and upper loop of jejunum, and lower risk of metabolic dysfunctions after duodenum-preserving pancreatic head resection may favour duodenum-preserving pancreatic head resection in recommended diagnoses. Attending physicians should be more encouraged to use a multidisciplinary approach to assess the suitability of surgical treatment in patients with chronic pancreatitis., (© 2024. The Author(s).)

Background: Pancreaticoduodenectomy is associated with an incidence of postoperative complications of approximately 41%. One of the most severe complications is a postoperative pancreatic fistula. The exact cause of postoperative fistula development is still unknown, but it appears to be multifactorial. Proper perfusion of pancreatic remnant is essential for the healing of pancreaticojejunostomy. To date, there is no method to reliably evaluate the vascular supply of the remnant. One of the methods for the assessment of organ perfusion is the indocyanine green fluorescence. This study aims to determine if indocyanine green fluorescence is a reliable method to measure the perfusion of the post-resection pancreatic remnant. The secondary outcome is to determine if intraoperative evaluation of the vascular supply of the post-resection remnant may predict the increased risk of postoperative pancreatic fistula development., Methods: This study is designed as a prospective, observational study. All consecutive patients undergoing open or robotic pancreaticoduodenectomies at our department during the 1st May 2024-31st December 2026 period will be enrolled. The exclusion criteria are an allergy to indocyanine green and refusal by the patient. The adequacy of the vascular supply of the post-resection pancreatic remnant will be intraoperatively evaluated using a fluorescence detector. Patients will be divided into two groups: Those with high risk of pancreatic fistula development and those with low risk. The incidence of pancreatic fistulas in both groups is to be compared. Postoperative data including morbidity, mortality, hospital stay, intensive care unit stay and postoperative fistula development will be collected., Discussion: If an intraoperative assessment of the perfusion of post-resection pancreatic remnant using indocyanine green is proven to be a suitable method to estimate the increased risk of the pancreatic fistula, the list of the existing known risk factors could be expanded. In the most high-risk patients the modification of the surgical procedure could be considered., Trial Registration: Number: NCT06198400 ClinicalTrials.Gov. Date 08.01.2024., (© 2024. The Author(s).)

Hemobilia is a rare condition defined as bleeding in the biliary tract. The clinical presentation is variable. The typical manifestation consists of jaundice, upper gastrointestinal bleeding, and right upper quadrant abdominal pain. This set of symptoms is known as "Quincke's triad." It is present in only 22%-35% of cases. Post-traumatic hemobilia is an extraordinarily rare condition occurring in only 6% of the patients with hemobilia. In general, it occurs in less than 0.2% of patients with liver trauma. A delay in the development of bleeding after liver trauma is frequent. Early diagnosis is essential because massive bleeding into the biliary tract is a potentially life-threatening condition. We present a case of a patient with massive hemobilia developed 12 days after blunt abdominal trauma. Computed tomography angiography showed two pseudoaneurysms in hepatic segments V and VIII with contrast medium extravasation. We successfully performed digital subtraction angiography with selective transcatheter arterial embolization of the leaking segment VIII pseudoaneurysm. Embolization of the pseudoaneurysm in segment V was technically impracticable. Our article provides a review of the published literature focussing on the prevalence, diagnostics, and treatment of post-traumatic hemobilia., (© The Association of Military Surgeons of the United States 2022.

Objectives: The vascular supply to the neck and body of the pancreas is highly variable. The dorsal pancreatic artery is the dominant artery feeding this area. The aim of this study was to describe the vascular supply of postresection pancreatic remnants after pancreaticoduodenectomy. Patients with hazardous anatomical arrangement may be at a higher risk of postresection remnant ischemia and postoperative pancreatic fistula development., Methods: The modified Whipple procedure was performed on 20 cadaveric donors. The macroscopic anatomical supply of the postresection pancreatic remnant of each donor was evaluated., Results: The arterial supply of the postresection remnant was highly variable. In 30% of cases (6/20), the dorsal pancreatic artery was cut during the pancreatoduodenectomy or it was missing. In these cases, the area of the pancreaticojejunostomy construction was fed only through anastomoses between the transverse pancreatic artery and the pancreatic branches of the splenic artery., Conclusions: In 30% of cases, the arterial supply of the postresection pancreatic remnant was dependent on inconstant intraparenchymal arterial anastomoses. These patients may be at a higher risk of postoperative pancreatic fistula development., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2023 the Author(s).

Introduction: Schwannomas are a group of well differentiated benign tumors originating from the Schwann cells of the peripheral nervous system. Their localization in the pelvis is very rare. Schwannomas with expansive growth can cause wide neurologic symptoms or oppression of pelvic organs., Case Report: The authors present a case study of a 60-year-old woman with a large, symptomatic deep pelvic schwannoma. The patient underwent robotic-assisted surgery resulting in complete tumor extirpation. The patient's postoperative course was uneventful with a total of two hospitalization days. The diagnosis of a schwannoma was confirmed by histopathologic analysis. At 11-month follow-up surveillance the patient did not present any neurological deficit or other symptoms., Conclusion: Robotic-assisted surgery allows safe and effective surgical treatment in difficult-to-access anatomical areas. Magnetic resonance imaging is required for preoperative imaging of neurogenic tumors. Histological verification is not recommended in cases where evidence of a schwannoma is found. Multidisciplinary cooperation of a dedicated team experienced in minimally invasive pelvic surgery is necessary.

Background: Postoperative pancreatic fistula is one of the most dreaded complications following pancreatic resections with Grade C the most severe. Several possible types of surgical intervention are available but to date, none of them have clearly shown superiority. This study aims to compare different surgical approaches., Methods: A retrospective analysis of patients who underwent revision surgery for postoperative pancreatic fistula between 2008 and 2020 was performed. Three surgical approaches were compared: open drainage; a disconnection of the pancreaticojejunostomy; and salvage total pancreatectomy. The data of nine monitored parameters were collected. Selected parameters were statistically analyzed and compared., Results: A total of 54 patients were included. Eighteen patients underwent open drainage, 28 had disconnections of the pancreaticojejunostomy and eight had salvage total pancreatectomy. Statistically significant differences were observed in the time of Intensive Care Unit stay, the number of surgical interventions, 90-day mortality, the number of administered blood transfers and treatment costs. Open drainage showed to be superior in each category. The difference in long-term survival also slightly favored simple drainage., Conclusion: Open drainage procedure showed to be superior to other types of interventions in most of the monitored parameters. Disconnection of the pancreaticojejunostomy and a salvage total pancreatectomy had similar results, which correlated with the surgical burden of these interventions., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2022 Záruba, Rousek, Kočišová, Havlová, Ryska and Pohnán.)

Background/objectives: The dorsal pancreatic artery is the main artery of the body and tail of the pancreas. Its origin and branching is highly variable. The aim of this study was to perform a meta-analysis to generate pooled prevalence data on the presence and origin of the dorsal pancreatic artery. Clinically important aspects of the dorsal pancreatic artery were summarised during the literature review., Methods: Major medical databases were searched. Data on the presence and point of origin of the dorsal pancreatic artery were extracted and quantitatively synthesised. The obtained data of anatomical based studies and computed tomography based studies were statistically analysed., Results: In total, 30 studies, comprising 2322 anatomical and computed tomography based cases were included. The dorsal pancreatic artery was present in 95.8% of cases. It originated from the splenic artery in 37.6% of cases, common hepatic artery in 18.3% of cases, coeliac trunk in 11.9% of cases and the superior mesenteric artery in 23.9% of cases. Other rare origins were present in 2.77% of cases. Multiple dorsal pancreatic arteries were found in 1,7% of cases. There was no significant difference in the presence or origin of the dorsal pancreatic artery between anatomical and computed tomography based studies., Conclusion: The dorsal pancreatic artery is present in the vast majority of cases. Its origin and branching are highly variable. Multiplicity of the dorsal pancreatic artery is infrequent., Competing Interests: Declaration of competing interest The authors declare that they have no competing interests., (Copyright © 2022 The Authors.

Introduction: Multidisciplinary teams (MDTs) have become a standard part of treating oncological patients. Based on the available data, they have lead to significantly higher survival rates in the treatment of colorectal cancer (CRC). Reported negatives include potentially longer times between diagnoses and the start of appropriate treatment, and the lack of quality controls over the MTDs actions. This report aims to assess the benefits of MDTs using our own data set for 2017., Methods: Year 2010 saw the institution of an MDT at the Central Military University Hospital in Prague, with the obligation to refer CRC patients to the MDT before the start of treatment. Having standardized the registration, we have implemented a simple procedure to track the quality of our MDTs involvement and its patient benefits: number of patients, number of referrals with proposed diagnostic and therapeutic procedure, frequency and reason of changes to original strategies, and the frequency of variations from the MDTs conclusions., Results: 405 CRC patients were referred to the MDT in 2017; we have found 499 referrals in this group. The data set was formed predominantly by men (61%), with the mean age of 63 (21-91), and the median age of 64.5 years. Surgical treatment was the most commonly proposed procedure (59%), followed by systemic treatment or, as the case may be, radiotherapy. In 24% of the cases, the conclusion did not match the originally proposed procedure. The decision not to go through with the proposed surgical treatment was the most common change (66 %). We have found a difference in the quality of referral in patients examined specifically by the referring doctor, as opposed to patients whose medical records have just been sent in. We have found therapeutic variation in the MTDs conclusions in less than 5% of patients., Conclusion: Having analyzed our data for CRC patients referred to the MDT in 2017, we have found out that in 24% of the patients, the MDT referral leads to a change in the originally proposed diagnostic and therapeutic procedure. Consensus among the MDTs members on the CRC patients treatment guarantees an optimum procedure. What is fundamental is that the referring doctor knows the patient. Constant tracking of the MDTs outputs forms a condition for sustaining the quality of its work and a base for assessing its benefits to the patients.

Introduction: Acute appendicitis is the most common cause of intra-abdominal emergency surgery worldwide. The approach to its treatment keeps changing. The number of acute appendectomies has been decreasing. Many patients are treated conservatively with success. Our study compares conservative and surgical treatment of acute appendicitis, including its complications in our department., Methods: We retrospectively analyzed the group of 117 patients hospitalized with the clinical diagnosis of acute appendicitis. We distinguished patients with complicated and uncomplicated appendicitis, and patients operated and treated conservatively. We evaluated complication rates and recurrences of the disease, respectively, in 1-year follow-up. The Student t test and Fishers exact test were used for the statistical analysis., Results: In 2012 we hospitalized 117 patients with acute appendicitis: 83 patients (71%) for uncomplicated and 34 (29%) for complicated appendicitis. 41% of patients with complicated and 13% with uncomplicated appendicitis (p=0.02) were treated conservatively. Conservative treatment or laparoscopic surgery, respectively, were used more often in women ( p0.001). There was no failure of conservative treatment. Perioperative morbidity was 13%. No patient died. 6 patients (24%) of the conservatively treated group were hospitalized in the subsequent year for recurrent problems. 4 (16%) were reoperated. The rate of negative appendectomy (negative pathological findings) was 11%. The hospitalization time was shorter in patients treated conservatively or using laparoscopy, respectively, compared to the group of patients undergoing appendectomy., Conclusion: In the modern era of available complementary examinations and a broad spectrum of antibiotics the conservative approach is favoured as a treatment of complicated appendicitis. Conservative treatment of uncomplicated appendicitis is an option, but not the method of choice. Routine elective appendectomy after successful conservative treatment is groundless. Laparoscopic appendectomy is associated with lower morbidity than open appendectomy. Despite the available tests and scoring systems the negative appendectomy rate remains high., Key Words: appendicitis - appendectomy - laparoscopy - antibiotic treatment.

Background: The authors examined the incidence of musculoskeletal injuries according to their type and location in the period of winter at a highland hospital, which also functions as a regional hospital for a few winter sport resorts., Methods and Results: . In the sample there were 1644 patients (696 women, 948 men) treated for primary musculoskeletal injuries from 1.1. to 31.3.2008. This was a retrospective study; the data were collected from medical reports. It included: age, sex, mechanism of injury, diagnosis and whether the patient had to be hospitalised or not. Age of the patients ranged from 1 to 95 years with an average of 29 years (31 for women and 28 for men). Younger age groups dominated among men. After 70 years of age there was a prevalence of women. Fractures were the most common cause of injury (653, 39.7%), followed by injuries to the joints' ligamentary apparatus by mechanism of distortion (379, 23.1%). Next in incidence were soft tissue injuries caused by contusion (325, 19.7%) and open wounds (241, 14.7%). The least common were luxated joints (43, 2.6%) and closed injury to muscles and tendons (3, 0.1%). The most frequent site of injury was the hand (404, 24.6%), while the least frequent place was the thigh (17, 1.0%)., Conclusions: In conclusion the study confirmed that other than the age, gender and the season, the geographic location also influences the spectrum of musculoskeletal injuries. The study also showed that the most common type of injuries was that of the upper extremity. The study did not confirm the expected prevalence of fractures among women. The prevalence of men was probably because of the prevalence of winter sport activities as a leading cause of injury (mostly skiing and snowboarding).
