Comparing the efficacy of EUS versus MRCP with ERCP as gold standard in patients presenting with partial biliary obstruction - finding a better diagnostic tool.

Objective: To evaluate the diagnostic accuracy of different imaging modalities in patients with partial biliary obstruction with no obvious aetiology on initial imaging. Methods: This is a prospective single-centre cohort study carried out at Pak Emirates Military Hospital, Rawalpindi from June 2019 to June 2021 with non-probability consecutive sampling. Patients with ages 16 to 75 years, presenting with partial biliary obstruction and undetermined aetiology on initial imaging (TUS and MRCP) were enrolled. EUS was performed for each of these patients and the case was regarded as "true positive" or "true negative" if the findings of imaging modality correlated to those of ERCP. ROC curve, sensitivity, specificity, PPV, NPV and AUC (with 95% confidence interval) were drawn for all the diagnostic tools using SPSS V. 21. Results: A total of 65 patients were enrolled over a period of two years with male to female ratio of 1.4:1. Forty-four patients had an intermediate risk of choledocholithiasis upon preliminary evaluation whereas, 48(74%) of the participants had CBD calculi or sludge confirmed upon subsequent ERCP. Trans-abdominal ultrasound showed the lowest sensitivity (29.2%), specificity (85%), NPV 12% and PPV 93% for diagnosing CBD calculi. This was followed by MRCP with a sensitivity of 37.5%, specificity of 100%, NPV of 36.2% and PPV of 100%. EUS showed the maximum diagnostic accuracy with AUC of 1.0 and a 100% sensitivity and specificity when compared with ERCP as gold standard. Conclusion: EUS is superior to MRCP in terms of diagnostic accuracy as minimally invasive diagnostic tool and EUS superiority is particularly relevant in patients with intermediate risk of choledocholithiasis.

Does patient's position count during Endoscopic Retrograde Cholangio-pancreatography? Left lateral decubitus versus prone position.

Objective: To compare the efficacy and safety of left lateral decubitus versus prone position during endoscopic retrograde cholangio-pancreaticography (ERCP). Methods: This prospective single-centre cohort study was carried out at Pak Emirates Military Hospital from January to June 2021. Patients requiring ERCP were subsequently allotted LL or PP group randomly (unequal randomization) except patients with recent abdominal surgery, in-dwelling catheters, raised intra-abdominal pressure, cervical spine abnormalities and limb contractures. Qualitative data was analysed using frequencies and chi square statistics whereas, quantitative data was analysed using mean±SD and student T or Mann Whitney U-test. Results: A total of 114 patients were enrolled according to the inclusion criteria with 62(54%) males and majority of the patients (42%) belonging to the age group 31-45 years. The most common ERCP indication was choledocholithiasis (36%). Technical success was achieved in 109(96%) patients with no statistically significant difference between the two groups. The total time of procedure, time for deep cannulation, time for acquiring therapeutic goal and ERCP complexity level were all similar between the two groups. The rate of inadvertent PD cannulation and PEP were relatively higher for the PP group but were statistically non-significant through univariate and logistic regression analyses and the only outcome measure that showed significance was multiple cannulations in the PP group. Conclusion: The study concludes that LL is non-inferior to PP and both positions have comparable outcomes with non-significant differences in terms of technical success rate, complications (specifically PEP), total procedure time, time required for deep cannulation and attainment of goal, ERCP complexity level and inadvertent PD cannulation.

Does early application of needle-knife sphincterotomy (NKS) in patients with difficult biliary cannulation increase the risk of postERCP pancreatitis? A single centre study.

Objective: To determine that early needle-knife sphincterotomy does not increase post-ERCP pancreatitis in patients with difficult biliary cannulation as compared to standard cannulation. Method: This prospective single-centre cohort study was carried out at Pak Emirates Military Hospital from January 2021 to June 2021. Patients requiring ERCP were enrolled in the study (according to inclusion and exclusion criteria) and were subsequently allotted different groups according to the technique used for deep biliary cannulation. Qualitative data was analysed using frequencies and chi square statistics whereas, quantitative data was analysed using mean±SD and one way ANOVA test. Result: The cohort included 114 patients with 52.6% male patients and predominance of relatively younger age group (31-45 years). The most common indication for ERCP was choledocholithiasis (36%) with an overall technical success rate of 96%. Deep cannulation was achieved either through standard cannulation (56%), double guidewire and/or pancreatic stent assisted (10.5%), use of early Needle-Knife Sphincterotomy (19%), NKS as a last resort (3.5%) or Transpancreatic Stenting and/or combined sphincterotomy (6%). Pancreatitis as a complication occurred in 4(3.5%) patients, bleeding in 2(1.8%), on-table desaturation in 2(1.8%) and perforation in 1(0.9%) patient. The occurrence of pancreatitis was only related significantly to inadvertent PD cannulation through univariate and logistic regression analysis whereas, multiple cannulations (>5), gender, age, classification of papilla and the use of early NKS had no impact on pancreatitis or the occurrence of other complications. Conclusion: NKS is an effective and safe modality for deep biliary cannulation and achieving technical success where cannulation is deemed difficult and does not increase the risk of PEP if done by experienced endoscopists in high volume centres.

Addressing Osteonecrosis: A preventable catastrophe - A multi-center study.

Objectives: To assess the knowledge of medical doctors about osteonecrosis who prescribe radiotherapy and bisphosphonates and dentists who receive these patients with such risk factors. Methods: This cross sectional multicenter study was carried out from 15th October 2021 to 20th November 2021 in different set-ups of Pakistan. A validated and piloted questionnaire was sent to dental and non-dental doctors working in different set-ups of Pakistan through email. All data was analyzed in SPSS version 22 with p value <0.05 being significant. Results: A total of 400 completed responses were received. Only 58% and 67% of the participants were actively educating their patients regarding the hazards of bisphosphonate and radiotherapy, respectively whereas only 45% of the medical doctors referred their patients to dentists before prescribing bisphosphonates and/or radiotherapy. Although the medical doctors had a statistically better knowledge of the definition of osteonecrosis, overall both the dental and non-dental doctors performed poorly regarding answering the questions pertaining to definition, clinical features and risk factors. The dental doctors also showed a poor performance for more technical and in depth questions that was statistically related to lesser work experience, working in a tertiary care facility and previous exposure to such patients. Conclusion: The inadequate awareness of dentists and physicians about the prevention and management of osteonecrosis of jaw is alarming. Efforts should be undertaken to raise the knowledge of dentists and physicians in this regard.

Emergency management of avulsion injuries: from home to clinic: A multicentre cross-sectional survey among medical doctors and general public.

The objective of this multi-centre study was to analyse the knowledge of parents as compared to medical-doctors regarding avulsion-injuries. A validated and piloted questionnaire was circulated among two equal groups (130 participants each) of medical-doctors and the general public. Data was analysed using SPSS version 19. A total of 131 (89%) participants had a university degree and 185 (71%) had a full time employment. One hundred and eighty-seven (72%) participants reported having no previous information regarding avulsion injuries, 195 (75%) considered their level of knowledge inadequate, and 63 (24%) had a previous history of dental trauma. A statistically significant number had information regarding avulsed permanent-teeth replantation (p=0.02) but not deciduous-teeth (p=0.26), whereas only 39 (15%) were aware of the right medium for tooth storage. Having seen or sustained an avulsion-injury and a higher qualification were statistically related to correct responses for some questions. A total of 106 (41%) of the participants wanted to be educated through written-material. In conclusion, the first-aid knowledge regarding tooth avulsion injuries in our population, irrespective of their level of academic education, is poor and needs supervised training.

Meaningful in-training and end-of-training assessment: The need for implementing a continuous workplace-based formative assessment system in our training programs.

Objectives: To analyze the systems and tools involved in assessment of skill procurement and demonstrating workplace skills in postgraduate medical training. Methods: This cross-sectional survey was carried out by enrolling trainee doctors currently working in Medical, Surgical, Dental and Allied specialties of the country by sending a validated and piloted questionnaire through email. Data collection was done from 20th April to 20th May 2021. Data was analysed using SPSS v. 21.0. Results: A total of 351 completed responses were received from 10 major cities of the country. Multiple aspects of entry-into-training, in-training and end-of-training evaluation showed poor correlation with the required training goals. A comparison of assessment for entry-into-supervised training (FCPS-I) versus independent practice (FCPS-II) showed a dismal situation regarding assessing affective skills like leadership, teamwork, coping with pressure and self-awareness. The concept of maintaining portfolios was completely alien to the trainees and the assessment tools used for demonstrating workplace skills were outdated. The lack of a continuous, periodic and balanced assessment (65%); detailed feedback (61.5%); fair exams (59%); variability in scoring system (58%) and professionalism of the examiners (57.5%) were the most frequently selected perceived flaws in the assessment system by the participants. Conclusion: There are multiple lacunae regarding competency-based assessment systems in our training programs and a massive scope for improvement. Assessment systems should be implemented as continuous process of learning, self-reflection, feedback and revalidation throughout the training tenure at regular and multiple points.

A peculiar tale of vomiting - rumination syndrome in three adult patients.

Rumination syndrome is a functional gastrointestinal disorder with effortless, non-projectile regurgitation seen mostly in paediatric population and seems to be an uncommon gastrointestinal disorder due to lack of awareness among physicians. Here we report three such cases in adult patients that were labeled "refractory vomiting". No such case has been reported from Pakistan which makes this a unique case series. All of our patients were diagnosed within six to fifteen months of initial symptoms, hence a high index of suspicion is required for early diagnosis of Rumination Syndrome to avoid excessive and repeated investigations, causing emotional trauma and financial loss to patients and their families.

Residents' perspective on the quality of postgraduate training programs in Pakistan - the good, the bad and the ugly.

OBJECTIVES: To assess the satisfaction of trainees towards different attributes of their training programs. METHODS: This cross-sectional survey was carried out by enrolling trainee doctors currently working in Medical, Surgical, Dental and Allied specialties of the country by sending a validated and piloted questionnaire through email. Data collection was done from 1st to 31st January 2021 after taking ethical approval from the concerned authorities. Data was analysed using SPSS v. 19.0. RESULTS: A total of 516 completed responses were received from 15 major cities of the country. The overall perceived satisfaction towards clinical skills (42%), teaching skills (31.4%), personal growth and development (23.6%), research (21%) and supervisor's role (44.2%) were considerably low with the most common causes for non-satisfaction being poor work-life balance (59%), financial instability (54.5%), poor research facilities (53%), poor career guidance (44%) and poor skill development (42.4%) in descending order. Senior years of residency, government and private set-ups, less than four and greater than 13 residents on average with less than three supervisors per department, excessive duty hours and financial instability in-lieu of not doing locums were statistically related to poor satisfaction across majority of the facets of residency as well the overall satisfaction towards training programs. CONCLUSION: There is a tremendous scope for improvement in the recognized and partially acknowledged attributes of our training programs. Yearly feedback surveys involving residents is essential for enlightening the authorities and mitigating the trainees' grievances.

Is Telemedicine our cup of tea? A nationwide cross-sectional survey regarding doctors' experience and perceptions.

OBJECTIVES: To evaluate the experience and perceptions regarding Telemedicine and the perceived barriers among medical doctors. METHODS: This cross-sectional survey was carried out by enrolling practicing doctors of Pakistan with experience of ≥6 months by sending a validated and piloted questionnaire through email. Data collection was done from 10th October to 9th November 2020 after taking ethical approval from the concerned authorities. Data was analysed using SPSS v. 19.0. RESULTS: Two-hundred-forty responses were received with a response rate of 63%. Female participants (62.8%) were in majority and most of the participants were working in urban (88.5%) or semi-urban (9%) locality in either teaching (35.9%) or tertiary care hospitals (34.6%). Seventy-three percent of the doctors didn't receive formal training with more than half of the doctors reporting non-availability of infrastructure and specific hardware. A large number of the participants were concerned regarding the non-availability of regulatory bodies, evaluations and accreditations of the service providers, the risks of malpractice, missed-diagnosis, prescription errors and medico-legal issues. The availability of specific infrastructure was statistically related to the hospital setup, locality and the specialty of the participants. Lack of technological literacy and infrastructure were considered the main constraints for the public in using telemedicine. CONCLUSION: Evidence of effectiveness of telemedicine across different fields is inconsistent and lacks technical, legal, cultural and ethical considerations. Inadequate training, low level of technological literacy and lack of infrastructure are the main barriers in implementing tele-health. High-quality evidence based studies are required for practical and long-term policies.

A year of hepatocellular carcinoma at a glance. Demographics, biochemical and radiological characteristics and treatment modalities from a specialized facility of Pakistan.

OBJECTIVE: To analyse the relation of demographics of hepatocellular carcinoma with the aetiology in order to analyse tumour characteristics in relation to anti-viral therapy and the presence of viral-deoxyribonucleic acid/ribonucleic acid, and the treatment modalities offered. METHODS: The cross-sectional study was conducted at the Department of Gastroenterology, Pak Emirates Military Hospital, Rawalpindi, Pakistan, from January 1 to December 31, 2019, and comprised patients aged 18-70 years with diagnosed hepatocellular carcinoma. Demographic variables, biochemical analysis, including liver profile and stage of cirrhosis, viral-status, tumour staging and the treatment modalities offered were noted. RESULTS: Of the 195 patients, 148(76%) were males and 47(24%) were females. The overall mean age was 59.8±8.9 years. There were 187(96%) patients with cirrhosis, 183(94%) corresponded to viral hepatocellular carcinoma, 160(82%) had hepatitis C, 18(9%) had hepatitis B and 6(3%) had co-infection. Platelets and alanine transaminase had a significant relation across aetiological groups (p<0.05). The presence of viral polymerase chain reaction had a significant impact on tumour aggressiveness (p<0.05). And, 62(32%) patients were amenable to curative treatment. CONCLUSIONS: Viral infection was found to be the main cause of rising prevalence of hepatocellular carcinoma. Treatment modalities were found to be expensive, and expertise was lacking.

Knowledge and clinical practices of medical doctors regarding nutrition in cirrhosis patients - A multicentre study from Pakistan.

OBJECTIVE: To determine the nutritional knowledge and clinical practices of physicians regarding nutrition in cirrhosis patients. METHODS: This multi-centre cross-sectional knowledge and practice study was conducted at Pak Emirates Military Hospital, Rawalpindi, Bahria Town International Hospital, Rawalpindi, and District Headquarter Hospital, Mandi Bahauddin, Pakistan, from January to March 2020, and comprised physicians working in wards, out-patient and emergency departments. Data was collected through interviews using a self-generated structured questionnaire. Correct responses were scored 1 and incorrect ones as 0, with a maximum possible score of 13. Data was analysed using SPSS 16. RESULTS: Of the 92 participants, 52(56.5%) were males, while the overall mean age was 28.3±4years and mean years in service 3.7±3 years. The mean score obtained was 5.8±2.1. Of the total, 33(35.9%) physicians had received formal nutritional training, 27(29.3%) were giving regular nutritional counselling and 48(52.2%) wrongly believed in the implementation of restricted diets. A large number of participants incorrectly considered salt 61(66.3%), water 49(53.2%) and lipids/oils 24(26%) to be avoided in ascites. Mean knowledge scores varied significantly for physicians dealing with cirrhosis patients on a daily basis (p<0.001) and those who had received formal training (p=0.003). CONCLUSIONS: The nutritional knowledge of physicians regarding cirrhosis was found to be sub-optimal.

Successful treatment of refractory Gastric Antral Vascular Ectasia (GAVE) in a cirrhotic patient with transcatheter arterial embolisation in a tertiary care facility in Pakistan: A case report.

Gastric antral vascular ectasia (GAVE) is a rare but important cause of upper gastrointestinal bleeding that may present with refractory anaemia or overt gastrointestinal bleeding requiring multiple admissions and resuscitation. Although endoscopic therapies are considered first line treatment for the management of refractory gastric antral vascular ectasia, angiographic embolisation of the culprit vessel(s) may emerge as an effective and safe treatment modality in the near future. Here, we present the case of a middle-aged gentleman with refractory gastric antral vascular ectasia, who was not responding to repeated sessions of Argon Plasma Coagulation (APC) and was successfully treated with trans-catheter arterial embolisation of gastro-duodenal artery.

Outcome of patients with acute severe necrotizing pancreatitis in a dedicated hepato-biliary unit of Pakistan.

OBJECTIVE: To analyze the management of severe necrotizing pancreatitis in a specialized center of a lower middle-income country, Pakistan using multiple outcome measures. METHODS: All the patients in this prospective observational study with severe necrotizing pancreatitis being referred to Pak Emirates Military Hospital from January 2017 to December 2019 were followed over the course of their admission. Demographic data and disease outcomes were duly noted. Cox regression analysis was used to predict fatality outcome. RESULTS: A total of 57 patients with 48 (84.6%) infected necrotizing pancreatitis were managed in our set up. The most common etiology reported was gall-stones (37%) with male preponderance (72%) and a mean age of 50±11.3 years. The most common complications were acute-kidney-injury (63%), splenic-vein-thrombosis (21%) and ascites (21%). Fourteen patients required mechanical-ventilation with a mean duration of 7±1.4 days on respiratory support. Eight (14%) patients required Endoscopic-Ultra-Sound guided drainage and six (10.5%) underwent surgical-necrosectomy depending upon the patients' condition and collections characteristics. Mortality, as one of the main outcome measures, was reported to be 12.3% and was statistically related to mechanical-ventilation, organ failure and surgical-necrosectomy while 22 (38.6%) patients were discharged on pancreatic enzymes supplements and 7% required insulin. CONCLUSION: Survival outcomes with acute severe necrotizing pancreatitis are improving in a dedicated hepato-biliary unit internationally in lieu with a multidisciplinary team approach. Percutaneous and EUS guided drainage of pancreatic collections have turned out to be an important procedure to manage infected pancreatic necrosis that helps to avoid a morbid procedure in the form of necrosectomy.

Impact of COVID-19 pandemic on the residency programs of the country: A multicentre study.

OBJECTIVE: To provide an insight on the disruption of multiple facets of residency programs in a multi-centre study. METHODS: This cross-sectional survey was carried out by enrolling the available residents from three teaching hospitals of the country by sending a questionnaire through email. The questionnaire comprised of three parts; 1) basic demographics, 2) effect on multiple facets of training and 3) the use of smart learning with the support provided by the hospitals. Data collection was started during the first week of June 2020 after acquiring ethical approval from the concerned department and the total duration of the study was one month. Data was analysed using SPSS v. 19.0. RESULTS: A hundred-and-five completed responses were obtained with a response rate of 42%. Fifty-nine percent of the participants were female residents. Majority of the residents (69%) belonged to the age group 25-30 years. Fourth year residents (38%) showed maximum participation and the mean number of work days per month were 22±5.4. All of the aspects of training suffered complete or severe reduction except for the multi-disciplinary team (MDT) meetings, elective rotations and e-log book entries. Sixty seven to sixty-nine percent of the residents felt complete clinical, educational and psychological desertion in their departments, 59% used telemedicine and 90% reported non-availability of smart learning facilities. CONCLUSION: Overall, our study confirmed that the COVID-19 pandemic has substantially affected the clinical skills, teaching and personal growth of many trainees. There is a decrease in exposure to almost all of the aspects of training with no alternative in the form of smart learning provided to many. Clinical, educational and psychological support, although an extremely important part of healthcare staffing and management, has been largely neglected as well.

Amid COVID-19 pandemic, are non-COVID patients left in the lurch?

OBJECTIVES: 1) To explore the possible impact of the pandemic on the health seeking behavior of the patients, 2) To explore the relation of socio-demographics on the utility of health-care facilities. METHODS: This cross-sectional study was conducted by enrolling all patients ≥15 years of age presenting to the Out-Patient-Department of three main public-hospitals after obtaining ethical committee approval. A questionnaire with validated Urdu translation was filled by each participant that included socio-demographic data, pre-Covid and Covid-19 era health seeking behaviors and the impact of the pandemic on the utilization of healthcare facilities. Data was analyzed using SPSS V.19. RESULTS: A total of 393 patients were enrolled with a male preponderance (72%) and a median age range of 31-45 years. Fifty-eight percent of the study population was unemployed and 47.3% were seeking follow up care. The frequency of ER and multiple (>4 times) OPD visits were significantly decreased in the Covid-19 times whereas, the laboratory and radiology services were largely unaffected. A significant number of patients were not satisfied with the current healthcare facilities that was seen irrespective of the socio-demographic status. Emergency Room and radiology services were largely unaffected whereas, elective procedures and laboratory facilities were reported to be severely affected or delayed in relation to socio-demographic variables. CONCLUSIONS: Healthcare inequalities have widened and depression has shown a sharp rise during this pandemic. The over-burdened healthcare facilities at the verge of collapse may miss out on the chronic non-Covid patients which would ultimately lead to increased morbidity and mortality.

Safety of balanced propofol and midazolam in upper gastrointestinal endoscopy for sedation in cirrhotic patients.

OBJECTIVE: Sedation for upper gastrointestinal endoscopy (UGIE) in patients with cirrhosis is theoretically associated with high incidence of adverse events due to low levels of binding proteins and decreased hepatic clearance of drugs. The objective of the study was to assess the safety of combined propofol and midazolam sedation in cirrhotic patients undergoing UGIE. METHOD: A total of 500 patients undergoing UGIE were divided in to two groups in a prospective observational study from Jan 1st 2018 to June 30th 2018. Group (I) consisted of cirrhotic patients who underwent the procedure with sedation and Group (II) consisted of non-cirrhotic patients who opted for sedation. The main outcome measurements included vitals monitoring before, during and after procedure, total sedation dose, time to initial and deep sedation, recovery time and complications. RESULTS: There was no significant difference between sedation safety and rate of complications for the cirrhotic and non-cirrhotic patients except for the recovery period during initial 10 minutes. The Modified Aldrete score for the cirrhotic patients was 9.5±0.5 min as compared to 9.8±0.4 min for non-cirrhotic patients (p<0.001) at 10 minutes. Grade 2 hepatic encephalopathy was seen in 0.8% of the cirrhotic patients who required hospitalization for 24 hours. Also balanced sedation was acceptable by the patients and the endoscopists equally with statistically significant scores on endoscopist's assessment of co-operation and assessment of patient's satisfaction scores. CONCLUSIONS: Balanced propofol and midazolam sedation has a good index of safety for both cirrhotic and non-cirrhotic patients and is acceptable by the patients and endoscopists equally.

Hepatitis-associated aplastic anaemia: A case report from a tertiary care facility of Pakistan.

Hepatitis-associated aplastic anaemia (HAAA) is an uncommon variant of aplastic anaemia which may present as acute or chronic, mild and transient or fulminant disease. The development of aplastic anaemia is usually fatal if not treated in time, with mortality rate being as high as 85%. A high index of clinical suspicion is required for the diagnosis and exclusion of acquired forms of aplastic anaemia. Here we present a case of a 28-year-old male who presented with sero-negative hepatitis and rapidly progressive bone marrow failure who was given a trial of Granulocyte Colony Stimulating Factor followed by a successful allogenic bone marrow transplant.

Dubin-Johnson syndrome coexisting with glucose-6-phosphate dehydrogenase deficiency presenting after acute viral hepatitis.

Dubin-Johnson syndrome presents as asymptomatic recurrent hyperbilirubinemia, while Glucose-6-Phosphate-Dehydrgenase-deficiecy as acute haemolytic anaemia. We present a case with coexisting Dubin-Johnson syndrome and Glucose-6-Phosphate Dehydrogenase deficiency unmasked by acute viral hepatitis E.
