BACKGROUND Despite improvements, survival rates for gastric cancer remain low, even in developed countries, confirming the role of primary and secondary prevention. OBJECTIVE This study aims to demonstrate the role of additional suspension sutures on the esophagojejunal anastomosis (EJA) to strengthen the anastomosis, i.e., relieve the mechanical suture. METHODS A retrospective cohort study was conducted from 2011 to 2022 at the Clinic for Surgery, University Clinical Center Tuzla, Bosnia and Herzegovina. The experimental group consisted of patients placed with a suspension suture at the esophagojejunal anastomosis (EJA) site after total gastrectomy. The control group was patients without a suspension suture. The clinical and laboratory parameters available from the medical history were analyzed, X-ray passage, surgical complications, non-surgical complications, the length of hospitalization, the postoperative course, time of onset of postoperative complications, postoperative radiological follow-up and endoscopic postoperative follow-up were then analyzed. RESULTS A total of 212 patients were included in the study: 87 in the experimental group with suspension sutures on the EJA and 125 in the control group without suspension sutures on the EJA. The two cohorts did not differ in other clinicopathologic parameters except perineural invasion, which was more prevalent in the control group. Patients in both groups were anemic and elevated values of C reactive protein (CRP) and decreased levels of proteins, albumin and globulin, with no significant difference between the two groups. The most common general complication was pleural effusion (28%), followed by pneumonia (∼22%). The most common complication in the experimental group was an intraabdominal abscess, while in the control group, it was a surgical wound infection. CONCLUSION Our study did not show a statistically significant difference between the two analyzed EJA techniques created with a circular stapler, when it comes to postoperative course and outcome in patients with gastric cancer.

Enteric viruses are commonly found obligate parasites in the gastrointestinal (GI) tract. These viruses usually follow a fecal-oral route of transmission and are characterized by their extraordinary stability as well as resistance in high-stress environments. Most of them cause similar symptoms including vomiting, diarrhea, and abdominal pain. In order to come in contract with mucosal surfaces, these viruses need to pass the three main lines of defense: mucus layer, innate immune defenses, and adaptive immune defenses. The following atypical gastrointestinal infections are discussed: SARS-CoV2, hantavirus, herpes simplex virus I, cytomegalovirus, and calicivirus. Dysbiosis represents any modification to the makeup of resident commensal communities from those found in healthy individuals and can cause a patient to become more susceptible to bacterial and viral infections. The interaction between bacteria, viruses, and host physiology is still not completely understood. However, with growing research on viral infections, dysbiosis, and new methods of detection, we are getting closer to understanding the nature of these viruses, their typical and atypical characteristics, long-term effects, and mechanisms of action in different organ systems.

INTRODUCTION Bosnia and Herzegovina (B&H) belongs to the countries of the Western Balkan located in Southeast Europe with an area of 51 129 km. The country is located in the continental part of Europe and extends to the Adriatic Sea. B&H is bordering Croatia in the north, west, and south; in the east, the country is bordered by Serbia, in the southeast by Montenegro, and in the southwest by the Adriatic Sea (Figure 1). According to the 2013 population census, B&H has 3 531 159 inhabitants, which is significantly less than in the 1991 census when the country counted 4 377 033. There are 2 219 220 people living in the Federation of B&H and 1 228 423 in the Republic of Srpska, and 83 880 people live in the Brčko District.

The association between urine amylase levels and the development of post-operative complications after Whipple resection is still unknown. The aim of this study was to determine the prognostic value of urine amylase levels for post-operative complications in patients who underwent Whipple resection. In this retrospective-prospective cohort study we analyzed amylase levels in urine, serum, and drains in 52 patients who underwent Whipple resection preoperatively and on Post-operative Day 1 (POD1) after the intervention. Patients were followed up for 3 months to assess their predictive value for post-operative complications. In patients with complications, urine amylase levels were significantly higher on POD1 than before resection (198.89 ± 28.41 vs. 53.70 ± 7.44, p=0.000). Considering the sensitivity and specificity of the urine amylase level on POD1, an area under the ROC curve of 0.918 was obtained (p<0.001, 95% Confidence interval [CI]: 0.894-0.942). Patients with urine amylase levels ≥140.00 U/L had significantly higher risks of post-operative pancreatic fistula (POPF) grade C (definition of POPF done according to the ISGP) (RR:20.26; 95% CI: 1.18-347.07; p=0.038), readmission to hospital (RR: 6.61; 95% CI: 1.53-28.58; p=0.011), reoperation (RR: 5.67; 95% CI: 1.27-25.27; p=0.023), and mortality (RR:17.00; 95% CI: 2.33-123.80; p=0.005) than patients with urine amylase levels <140.00 U/L. Urine amylase levels on POD1 displayed strong and significant positive correlations with serum amylase levels (r=0.92, p=0.001) and amylase levels in drains (r=0.86, p=0.002). We can conclude that urine amylase levels on POD1 have good prognostic value for post-operative complications after Whipple resection and might be used as an additional predictive risk factor.

Introduction: Cancelling elective procedures on the day of surgery presents a constant problem in all higher-level medical facilities, and the research of causes, consequences and possible solutions is the duty of every facility in order to enhance the quality of healthcare services. Methods: This prospective study included all patients that were scheduled for surgery from March 2016 to November 2018 in the operating rooms at our Department of Surgery, including both performed and cancelled cases. Cases by different surgical departments (general surgery, gynecology, orthopedics, urology, plastic surgery, ophthalmology and otorhinolaryngology) were all included. Results: Out of 8201 planned elective procedures from March 2016 to November 2018 at the General Hospital “Abdulah Nakas”, 7825 cases were performed and 376 cases (4.58%) were cancelled on the day of surgery. The most common reasons for cancelling a surgical procedure on the day of surgery were: lack of time to perform surgery, (33.51%), surgery cancelled due to medical/anesthetic reasons, (31.38%), surgical procedure cancelled by the surgeon on the day of surgery, (11.97%). Conclusion: This study has shown that the percentage of elective cases cancelled on the day of surgery at our institution stands at an acceptable 4.58%. The most common reasons for case cancellation on the day of surgery were identified. The majority of reasons for cancellation were avoidable, which means that appropriate steps could contribute to lowering the percentage of cancelled elective cases and an improved quality of healthcare services.

A 47 year old man was admitted to hospital with abdominal pain, constipation and extreme abdominal distension. The patient did not have a regular bowel movement for the last two years of his life. He had been using laxatives, enema and went through manual removal of fecal impaction for the last 20 years of his life. At the age of 1, he underwent anal atresia surgery and Hirschsprung's disease (HD) was diagnosed at that time. The abdominal CT scan revealed massive fecal material in dilated colon and visible compressions of nearby structures. Medical consilium decided that the patient should undergo surgery, subtotal colectomy and unipolar colostomy. During the operation 21 kg feces was removed. The quality of life of patient improved significantly. Colostomy gave better results than treatment with laxatives for 20 years.

Cholecystostomy is considered to be a treatment option when conservative treatment of acute cholecystitis failed in elderly and critically ill patients. The aim of this paper is to present a cholecystostomy in the treatment of obstructive jaundice before the definitive operation for the underlying cause of jaundice. The patient in poor general condition with the obstructive jaundice was diagnosed to have a pancreatic head tumor. He had undergone the laparoscopic cholecystostomy. After improvement of the general condition and lower total bilirubin level, the patient had undergone to definitive procedure. It is shown that laparoscopic cholecystostomy can be a successful way for adequate bile drainage in a patient with poor general condition before the definitive treatment of obstructive jaundice.
