Validation of a Novel Smartphone-Based Electronic Data Capture System Following Surgical Fixation of Distal Radial Fractures

Background: Large prospective institutional data provide the opportunity to conduct level II and III studies using robust methodologies and adequately powered sample-sizes, while circumventing limitations of retrospective databases. We aimed to validate a prospective data collection tool, the Orthopaedic Minimal Data Set Episode of Care (OME), implemented at a tertiary North American health care system for distal radial fracture (DRF) open reduction and internal fixation (ORIF). Methods: The first 100 DRF ORIFs performed after OME inception (February 2015) were selected for this validation study. A blinded review of the operative notes and charts was performed, and extracted data of 75 perioperative DRF ORIF procedure variables were compared with OME collected data for agreement. Outcomes included completion rates and agreement measures in OME versus electronic medical record (EMR)-based control datasets. Data counts were evaluated using raw percentages and McNemar tests. Cohen (κ) and concordance correlation coefficient analyzed categorical and numerical variable agreement, respectively. Results: Overall, OME demonstrated superior completion and agreement parameters versus EMR-based retrospective review. Nine data points (12.0%) demonstrated significantly higher completion rates within the OME dataset ( P < .05, each), and 88% (66/75) of captured variables demonstrated similar completion rates. Up to 80.0% (60/75) of variables either demonstrated an agreement proportion of ≥0.90 or were solely reported in the OME. Of 33 variables eligible for agreement analyses, 36.4% (12/33) demonstrated almost perfect agreement (κ > 0.80), and 63.6% (21/33) exhibited almost perfect or substantial agreement (κ > 0.60). Conclusions: The OME is a valid and accurate prospective data collection tool for DRF ORIF that is reliably able to match or supersede traditional retrospective chart review. Future investigations could use this tool for large-scale analyses investigating peri/intraoperative DRF ORIF variables.

A retrospective study of ectopic pregnancy

Background: Ectopic pregnancy is one of the common acute abdominal emergencies posing a serious threat to life. The overall incidence of ectopic pregnancy is on a steady increase over the last two decades. Yet the case fatality rate has come down due to early diagnosis and management. 95% of ectopic pregnancies occur in the fallopian tube, and rest 5% cumulatively in the ovary, cervix, peritoneal cavity and previous caesarean section scar. The present study was done to analyse the associated risk factors, clinical manifestations and management options of ectopic pregnancy.Methods: This retrospective observational cohort study was done in the Department of Obstetrics and Gynaecology, at Sri Venkateshwaraa Medical College, Hospital and Research Centre, Ariyur, Puducherry, between January 2018- November 2021. Data was collected from the case sheets, operative notes and a retrospective analysis of the cohort of patients with ectopic pregnancy was done.Results: This retrospective study was conducted from January 2018 to November 2021 involving a total of 50 cases. We found that majority of tubal gestation occurred in the age group 26-30 years 58.6% and 13.7% in the age group more than 30 years. Majority of patients 65.5% underwent U/L salpingectomy.10.34% underwent salpingo oophorectomy. Fimbrial expression was done for two patients. Two patients underwent fimbriectomy. Cornual stump excision was done in two patients. Hemoperitoneum was detected in 55.17% of cases.Conclusion: Ectopic gestation can become an obstetrical emergency and reproductive capacity hampering morbidity if not diagnosed and treated on time. However having a high vigilance and evaluating every woman in the reproductive age group who presents with the classical clinical triad of amenorrhea, pain abdomen and bleeding per vagina can help in curbing the incidence in future.

Quadriceps Tendon Autograft in Pediatric ACL Reconstruction: Graft Dimensions and Prediction of Size on Preoperative MRI

Background: There is increased interest in quadriceps autograft anterior cruciate ligament (ACL) reconstruction in the pediatric population. Purpose: To evaluate children and adolescents who underwent ACL reconstruction using a quadriceps autograft to determine the properties of the harvested graft and to assess the value of demographic, anthropometric, and magnetic resonance imaging (MRI) measurements in predicting the graft size preoperatively. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A retrospective database search was performed from January 2018 through October 2020 for patients undergoing ACL reconstruction. Patients <18 years old at the time of surgery in whom a quadriceps tendon autograft was used were selected. Demographic data and anthropometric measurements were recorded, and graft measurements were abstracted from the operative notes. Knee MRI scans were reviewed to measure the quadriceps tendon thickness on sagittal cuts. Graft length and diameter were then correlated with anthropometric and radiographic data. Results: A total of 169 patients (98 male) were included in the final analysis, with a median age of 15 years (range, 9-17 years). A tendon length ≥65 mm was harvested in 159 (94%) patients. The final graft diameter was 8.4 ± 0.7 mm (mean ± SD; range, 7-11 mm). All patients had a graft diameter ≥7 mm, and 139 (82%) had a diameter ≥8 mm. Preconditioning decreased the graft diameter by a mean 0.67 ± 0.23 mm. Age ( P = .04) and quadriceps thickness on MRI ( P = .003) were significant predictors of the final graft diameter. An MRI sagittal thickness >6.7 mm was 97.4% sensitive for obtaining a graft ≥8 mm in diameter. Conclusion: Our findings suggest that tendon-only quadriceps autograft is a reliable graft source in pediatric ACL reconstruction, yielding a graft diameter ≥8 mm in 82% of pediatric patients. Furthermore, preoperative MRI measurements can be reliably used to predict a graft of adequate diameter in children and adolescents undergoing ACL reconstruction, with a sagittal thickness >6.7 mm being highly predictive of a final graft size ≥8 mm.

O-BN05 The management of pancreatitis and complications that require intervention in a Benign Specialist Surgical Unit

Background Acute pancreatitis or inflammation of the pancreas is a common surgical pathology that presents with a spectrum of severity. The condition itself ranges from a mild/moderate self-limiting pathology to one associated with a systemic inflammatory response that can lead to organ dysfunction and death. We aim to investigate the aetiology/management and outcomes of patients presenting with pancreatitis in a benign specialist surgical unit with dedicated upper GI surgical care. Methods A retrospective analysis of all patients presenting and falling under surgical care with biochemical/radiological pancreatitis was conducted, using hospital archiving systems, reviewing operative notes and follow up events was conducted over an 8-year period. Results Within our benign specialist centre, 1393 patients were treated over an 8-year period. 73% of patients presenting with acute pancreatitis were male, whereas only 37% were female. The age range of patients presenting was 12 to 100 years, with the median age being 44 years. Within our population, 36.8% of acute pancreatitis was caused by gallstones, and 29.6% caused by alcohol and 33.6% other causes. 81% of patients seen had mild/moderate self-resolving pancreatitis requiring only fluids and analgesia. 19% had complicated pancreatitis requiring complex medical/surgical treatment.4.8% patients developed pancreatic necrosis, and 3.7% developed pancreatic pseudocysts. 8 patients required necrosectomy, 19 patients required cystogastrostomy and 1 patient required distal pancreatectomy with no 90-day mortality. Conclusions Our specialist unit with the support of gastroenterology, nutrition team, radiology and ITU have managed a large cohort of pancreatitic patients, the small number patients who require a surgical intervention have had good outcomes.

P-EGS02 Impact of delayed elective laparoscopic cholecystectomy on incidence and complications from gallstone ileus

Background The negative impact of the COVID-19 pandemic on the provision of elective surgery in the UK has been profound. Per the latest National figures, a total of 4.59 million patients are awaiting an elective operation (1). In our Trust, emergency operations and cancer service took precedence as we worked to minimize risks of COVID-19 while providing life-saving procedures. Subsequently, our ‘hot gallbladder’ operating list was put on hold for a period of 18 months. In our Trust, the current waiting time for an elective laparoscopic cholecystectomy is 52 weeks for symptomatic gallstone disease. Gallstone ileus is a well-recognized but rare complication of gallstones (2) and needs operative treatment. We performed this study to investigate the impact of delayed cholecystectomy on the incidence of gallstone ileus and the morbidity and mortality associated with this. Methods Retrospective study reviewing all acute admissions with gallstone ileus for 4 years from 2016 to 2020. Total number of patients was 19. Data collated from patient’s notes to include demographics and co-morbidities, operative notes, theatre records, and WebICE. Results Demographically, there was significant female preponderance (M : F : 1 : 18). Mean age of patients was 76.7 years. 17/19 patients underwent laparotomy as the primary operation (89%) and 1 (5%) had a laparoscopic procedure. 1 patient (5%) was managed conservatively. All patients had a CT scan as pre-operative imaging. 7 (34%) also had USS and 4 (20%) had MRCP. Mean length of stay in hospital was 13 days. 3 (15%) patients required re-admission to hospital for surgical and medical complications within 30 days. 3 (15%) patients returned to theatre for a second laparotomy within the index admission for recurrence of gallstone ileus. 8 (40%) patients had post-operative complications. There were 2 (10%) mortalities. 9 (45%) patients had gallstone related complications preceding their index presentation; majority (66%) which was calculous cholecystitis. The mean time between diagnosis of gallstone disease and emergency laparotomy for gallstone ileus was 38 months. Conclusions Gallstone ileus can be a life-threatening complication of gallstone disease and needs prompt recognition and treatment. Patients with known gallstones with symptoms of bowel obstruction should have a CT scan at time of presentation. Surgery is the mainstay treatment following resuscitation and concurrent conservative management. Early elective laparoscopic cholecystectomy can prevent mortality and morbidity from emergency laparotomy for gallstone ileus.

Laparoscopic donor nephrectomy: technique and outcome, a single-center experience

Background Laparoscopic donor nephrectomy (LDN) has been established as a surgical standard for living kidney donation. The aim of this work is to report our own experience with LDN regarding outcome and technique. Methods We prospectively identified 110 LDN cases between May 2017 and April 2020. Donor case files and operative notes were analyzed for age, sex, laterality, body mass index, warm ischemia time (WIT), intraoperative and postoperative complications, operative time, and length of hospital stay (LOS). Data were analyzed using SPSS version 10 (SPSS: An IBM Company, IBM Corporation, Armonk, NY, the USA). Results The mean age was 38 years, and 77% were males. Three cases (2.72%) required conversion to conventional open donor nephrectomy (ODN). Nevertheless, none of cases required intraoperative blood transfusion. The mean WIT was 2.6 min. Two cases (1.8%) developed major vascular injury (Clavien grade IIIb) and required conversion to ODN. Postoperatively, one patient (0.9%) needed transfusion of one unit of packed RBCs (Clavien grade II). The mean LOS was 2 days. Most common early postoperative complication was ileus (Clavien grade II) that developed in 4 (3.6%) cases. Incisional hernia (Clavien grade IIIb) was encountered in two (1.8%) cases. Two (1.8%) cases developed wound infection at the incision site and treated conservatively (Clavien grade I). Conclusions LDN is a safe technique with accepted intraoperative and postoperative morbidity. It offers short hospital stay, better cosmesis and early convalescence. In experienced hands, it can effectively deal with various vascular and ureteral anomalies without compromising early graft function.

EP.TH.1029Surgery for retained gallstones: A single centre experience

Aims Lost spilled gallstones during laparoscopic cholecystectomy is a rare inadvertent complication results in recurrent delayed sepsis. Diagnosis is made via retrospective review of operative notes. 2 cases of retained gallstones were removed surgically, following several years after the initial laparoscopic cholecystectomy. Conclusion 2 cases presented with delayed symptoms of abdominal pain, sepsis with intra-abdominal collections. Intra-abdominal abscesses treated with percutaneous USS guided drainage & antibiotics. Abscesses arise in right subphrenic space, right anterior abdominal wall & iliacus as a result of gallstone migration. Diagnosis of “spilled lost gallstones” was delayed until confirmation of retained gallstones on radiological imaging. Combination of USS, CT and MRI scan enabled to detect retained gallstones (radiolucent or radio-opaque) within an abscess cavity. Multi-disciplinary approach allowed a more concerted management i.e. diagnosis of retained gallstones & planning surgical exploration for retained gallstones. Ultimately, abscesses should be drained (percutaneously or surgically), and retained stones should be removed. Ideally this is done via minimally invasive techniques, but open surgery is often required. Use of laparoscopy enables exploration of the peritoneal cavity and any abscess cavity. This exploration will extract any fragment of gallstone that could be a nidus for continuous infection.

EP.FRI.489 Audit of emergency Operation notes (audit cycle)

The Royal College of surgeons has recommended guidelines for documenting operative surgical notes. An operation note must include ample information about the operation. In our initial audit, we found some areas for improvement. This re-audit of operative notes was aimed to review compliance with the guidelines by the Royal College of Surgeons and to identify areas of further improvement. Methods The notes of all patients who underwent emergency surgery from 1st of January to 15th of March 2020 under the General Surgical department were reviewed. Endoscopic procedures were not included in the study. Electronic records were used to review the operation notes. Results Notes of a total of 176 patients were included in the study. Significant improvement was seen in most of the domains. Compliance of 100% was seen in documenting operative findings, type of incision, wound closure technique, procedural details, documenting extra procedures, and post operative instructions. 17.6% notes did not clearly document the indication/diagnosis for surgery. 15.3% notes missed information about DVT prophylaxis. 25.57%notes did not include information about peri-operative antibiotics in the context of prophylaxis or post-op need. A significant number (71.6% ) of the notes were missing information about operative blood loss if there was any or none. Conclusion Overall operation notes detail most of the information expected by the Royal College of Surgeons. The key areas for improvement are to include specific details about the following:

EP.WE.28Routine histopathology examination of the sleeved stomach after sleeve gastrectomy - significance and comparison with preoperative endoscopy

Background Sleeve gastrectomy (SG) is one of the most commonly performed bariatric procedures. However, the available literature on histological examination of the resected sleeved stomachs is widely inconsistent. This study aimed at assessing the histopathological findings after SG performed in our center compared to the routinely performed preoperative esophagogastroduodenoscopy (OGD) and the intraoperative findings. Material and methods We conducted a retrospective cohort study using the bariatric unit database of all patients who had SG procedures from June 2007 to December 2019. Results Out of the 620 SG performed, there were 219 patients with complete data, including preoperative OGD reports, operative notes, and postoperative histopathology reports. We found normal specimens in 43.83% (n = 96) and evidence of inflammation in 50.68% (n = 111) of cases. There were 10 (4.56%) specimens with evidence of inflammation and other lesions and two (0.91%) specimens with lesions only. Twenty-five patients had inflammation, and 10 had lesions on preoperative OGD with negative histopathology reports. Conclusion Routine histopathology examination after SG does not change the management, and preoperative OGD can detect inflammatory changes and lesions, which could have been missed with histology analysis only.
