Publication Bacteriological Profile of Surgical Site Infection Following Gastrointestinal Surgery and Their Antibiogram(Nepal Health Research Council, 2023) Shrestha, Neha; Sharma, Sangita; Ghimire, Bikal; Prasad, Pravin; Das, Debashis; Sherchand, Jeevan BahadurAbstract Background: Surgical site infection is one of the common complication following abdominal surgery. It causes great morbidity and mortality, further increasing prevalence of multidrug resistant bacteria have made its management very challenging. The current study aims to identify causative agent responsible for surgical site infection and their antibiotic resistance patterns. Methods: This study was conducted among patients developing surgical site infection following gastrointestinal surgery in Tribhuvan university teaching hospital over a period of one year. The samples were collected and processed according to standard methods. The bacterial pathogens with their antimicrobial susceptibility were determined and resistant pattern like methicillin resistant Staphylococcus aureus and extended spectrum beta lactamase were further detected. Results: A total of 832 patients had under gone gastrointestinal surgery during the study period. Among them, 162 cases (19.5%) developed surgical site infection and 125 cases showed growth in culture. A total of 160 aerobic bacteria were isolated; Escherichia coli (29.9%) was the commonest organism with 40.8% being extended spectrum beta lactamase producer and 47.4% of Staphylococcus aureus were methicillin resistant. About 75.9% (85/112) of gram negative bacteria and 60.4% (29/48) gram positive bacteria were multi drug resistant. Conclusions: The burden of multi drug resistant bacteria causing surgical site infection is high which needs to be addressed timely. Good surveillance of bacterial antibiogram and rational antimicrobial use is necessary to reduce emergence and spread of resistant bacteria.

A new entity was proposed by Saxon Connor “Post-Operative pancreatitis”, which is defined by raised serum amylase more than the upper limit of institutional serum amylase value on Post-Operative day 0 or 1. There has been shown to be an association between postoperative pancreatitis and postoperative pancreatic fistula. We have conducted this study to see the incidence of postoperative pancreatitis and its association with postoperative pancreatic fistula. Methods: This was a prospective observational study. All patients undergoing pancreaticoduodenectomy at a tertiary care center for one and a half years were included. A cut-off value of serum amylase 80U/L was used to make a diagnosis of postoperative pancreatitis. The patients were followed up for one month. Pancreas specific complications were defined according to the definition given by the International Study Group of Pancreatic Surgery. Results: A total of 49 pancreaticoduodenectomies were done in the given period. The incidence of postoperative pancreatitis was 31(63.3%) and postoperative pancreatic fistula was 19(38.8%). Postoperative pancreatic fistula was seen in 19(61.2%) of patients having postoperative pancreatitis (P<0.001). Post-operative pancreatitis was also significantly associated with post pancreatectomy hemorrhage, increased hospital stay, and mortality. In multivariate analysis, preoperative endoscopic biliary drainage and increased serum amylase on the first postoperative day came out to be an independent predictor of postoperative pancreatic fistula. Conclusions: Post-operative Pancreatitis was associated with an increased incidence of Post-operative pancreatic fistula and other postoperative complications like Post pancreatectomy hemorrhage and mortality.
