Background/Aim. Surgeon-specific experience as measured by procedure volume can have a significant impact on survival of patients with rectal cancer (RC). The aim of this study was to determine whether an individual surgeon-specific volume of procedure influences early postoperative outcomes as well as to determine the strength of different groups of annual surgeon volume (ASV), as a predictor of outcomes in patients after RC resection up to 30 days postoperatively. Methods. This retrospective observational single center study involved a cohort of 546 patients of both sexes, operated for a 10-year period due to RC. Patients were divided into three groups, according to the annual volume of RC procedures of a surgeon who operated them. Seven outcomes were analyzed: the incidence of colorectal anastomotic dehiscence (CRAD), operative time, intraoperative blood loss, hospital stay, in-hospital death, the status of the circumferential resection margin (CRM) and the total mesorectal excision (TME) with number of lymph nodes, as well as some risk factors (several independent, dependent and ?confusing? variables) of importance for the outcome, to explain the difference. The strength of each group of surgeons and their effect on early outcome of treatment were determined. Results. The majority of surgeons (77.7%) belonged to the low and medium ASV, which performed a slightly higher number of surgeries (281) than the high volume group. The high-volume surgeon group was associated with significantly better results in four outcomes (CRAD, operating time, CRM, TME and number of lymph nodes). Conclusion. In our surgical institution, the high volume surgeon remains an important predictor of success of the RC surgery.

Introduction: Gastrectomy is one of the most common surgical methods for the treatment of gastric cancer, which basically destroys the mechanism and digestion chemistry. Reconstruction after gastrectomy attempts to optimize the antireflux and nutritive component of the postgastrectomic syndrome.Objective: To determine which reconstructive method after gastrectomy has the optimal synthesis of antireflux and nutritional components.Patients and Methods: 111 patients were treated for gastric malignancies at the Surgical Clinic of the University Clinical Center in Banja Luka, which were operated with the intention of achieving curability.Results: Based on Fisher’s exact probability test there is no statistically significant difference (p> 0.05) in mortality compared to the restoration of digestive continuity after gastrectomy. Reflux oesophagitis is the dominant modality of morbidity in omega-loop reconstruction (p <0.05). There is no statistically significant difference (p> 0.05) in late dumping syndrome in patients relative to individual gastric substitution options. In the Hunt-Lawrence-Rodino pouch reconstruction option, there is no statistically significant difference (p> 0.05) in the participation of individual modalities of meal quantity in relation to the condition before the disease or the modality of the nutritional status. .Conclusion: The results indicate the antireflux component of reconstruction Roux en Y and the advantage of the nutritive component in the loop modification (the creation of the Hunt-Lawrence-Rodino pouch).

Treatment results of 200 injured with the lesions of 282 magistral blood vessels were analyzed. All were combat injuries, and the majority was caused by the fragments of explosive device. The mechanisms of such the injuries produced large defects of soft tissues as well as the high level of the wound contamination, which aggravated reconstructive procedures and increased the risk of infection. In the majority of cases anatomic reconstruction of the artery was performed, and the ligature was used only in the case of graft infection and in the injuries of one artery of the lower leg or the forearm. The majority of injuries was solved by lateral suture or patch plastic, since postoperative constriction caused by those methods did not cause greater hemodynamic disorders due to the size of venous lumen. The duration of ischemic interval was of the utmost importance for the favorable final result of the treatment, as well as the adequate debridement of the wound, good soft-tissue cover of the reconstructed blood vessel and precise atraumatic technique. Total percentage of amputations was 14.5%, and all were involving the lower extremities, and were mostly caused by popliteal artery lesion. Language: sr
