ABSTRACT
Introduction: Postpancreatectomy hemorrhage (PPH) is an important complication which significantly increases morbidity and mortality following pancreaticoduodenectomy (PD). This study aims to find the incidence, classification, management, and mortality associated with PPH following PD. This study also describes the changes in management and outcomes between the period of 2004-2014 and 2015-2019 in our institute as in the later time period there was use of CT angiography and interventional radiology (IR) to identify and control the bleeding site.
Methods: This is a retrospective study in which medical records of patients having PPH following PD between 2004-2019 were analyzed. The grading and classification were done according to the International Study Group of Pancreatic Surgery (ISGPS). Management and outcomes were analyzed using standard descriptive statistics.
Results: A total of 43 patients developed PPH out of 336 PDs. Out of 43 patients, 4 (9.3%) had Grade A, 16 (37.2%) had Grade B and 23 (53.5%) had Grade C PPH. Fifteen (35%) patients were managed conservatively, seven (16.2%) with IR procedure and 21 (48.8%) were reexplored. There were 16 (37.2%) mortalities, out of different factors- intraoperative blood loss >500 ml showed the predictability for mortality (p= 0.01). On comparing two time periods it was seen that the PPH rate was almost similar but the mortality decreased from 58.8% to 23.07%.
Conclusion: PPH following PD is associated with high mortality. Increased use of IR procedure and CT angiography can decrease the relaparotomy rates and eventually decrease mortality.

Does Drilling Induce Hearing Loss after Modified Radical Mastoidectomy? A Retrospective Study
(Institute of Medicine, 2020) Neupane, Yogesh; Kharel, Bijaya; Dutta, Heempali
ABSTRACT
Introduction: Incidence of sensory neural hearing loss following mastoid surgery varies from 1.2 – 4.5%.There are various causes for postoperative sensorineural hearing loss during mastoid surgery. This study aims to identify whether there is any correlation between drilling and postoperative sensory neural hearing loss.
Methods: A retrospective study was conducted in the Department of ENT from January 2018 to June 2019. A total number of 68 patients above five years of age who underwent modified radical mastoidectomy for chronic otitis media squamous were included. Revision surgery, preoperative sensorineural hearing loss, injury to the ossicular chain during surgery, patients with lack of follow up or doubtful reports in mentally challenged were excluded from the study. The average bone conduction threshold was calculated from 500, 1000, 2000, 4000 Hz and compared using the Wilcoxon signed-rank test.
Results: There were 43 males and 25 females in the study with a median age of 23.5 years (16-55). The mean preoperative bone conduction threshold in the four frequencies of 500 Hz, 1kHz, 2kHz, 4kHz were -2.06dB, -2.06dB, 3.31dB, 4.63 dB respectively and the mean postoperative bone conduction thresholds were 1.03, 1.32, 5.29, 4.04 respectively. There was a decline of mean of 3.09 dB and 3.38dB only at the low-frequencies (500Hz and 1kHz) BC threshold respectively which were statistically significant, whereas at higher frequency there was no decline in average postoperative BC threshold.
Conclusion: There is no definite role of drill in inducing hearing loss and if present other causes of hearing loss should be sought in postoperative sensorineural hearing loss.

ABSTRACT
Introduction: Normal orbital dimensions are important for diagnosing orbital pathologies. Computed tomography (CT) of the orbit is an important modality offering high accuracy for precise measurements of orbit. The study was disbursed to ascertain criteria for the normative values of the various orbital dimensions using computed tomography in patients visiting Tribhuvan University Teaching Hospital, Kathmandu.
Methods: Orbital volume, ocular diameter, length of the interzygomatic line (IZL), the distance of the posterior extent of the globe from the interzygomatic line, globe position, diameters of extraocular muscles (medial, lateral, superior group, and inferior rectus) and lens density were measured in each eye of 172 patients undergoing CT examination of paranasal sinuses. The correlations with age and sex were also analyzed.
Results: Mean values (mean±SD) of orbital volume, ocular diameter, IZL, globe position and lens density were 24.54±2.57 cm3, 2.44±0.22 cm, 94.3±6.2 mm, 12.3±2.4 mm and 141.43±16.62 HU respectively. Mean diameters of extraocular muscles were 3.67± 0.52 mm, 3.36± 0.50 mm, 3.74±0.42 mm and 3.87±0.38 mm for medial rectus, lateral rectus, inferior rectus and the superior group respectively. There was no significant age and gender difference in most of the measurements. There was significant positive correlation of age with lens density, orbital volume and ocular diameter (p<0.05).
Conclusion: Normative data of different orbital measurements were obtained. The present result may help radiologists and ophthalmologists to accurately assess various orbital parameters, particularly in Nepalese populations.

Head Injuries at the Emergency Department of a University Hospital in Kathmandu
(Institute of Medicine, 2020) Henriksson, Thérèse; Kjellberg, Jacob; Shakya, Yogendra; Kurlberg, Göran
ABSTRACT
Introduction: Traumatic head injuries constitute a major cause of morbidity and mortality worldwide. The developing world is particularly affected due to a high prevalence of risk factors and difficulties in enforcing preventive efforts. This study was carried out at the Emergency Department (ED), Tribhuvan University Teaching Hospital (TUTH), Kathmandu, Nepal – where head injuries account for five per cent of all emergency visits. The aim was to describe demographics, cause of trauma, type of injury, and severity according to the Glasgow Coma Scale (GCS), as well as the outcome of emergency attendance in patients seeking medical care for traumatic head injuries. Auxiliary aims were to study correlations between age, cause of trauma and injury severity.
Methods:Data from 577 cases of head injuries from June to October 2019 were collected retrospectively.
Results:Traumatic head injuries accounted for 5.2 % of all emergency visits. The median age was 23 years. Patients were predominantly male. Superficial injuries and concussions were the most common. Most injuries were mild (94.4 %, GCS 13–15) and caused by falls (51.3 %) or road traffic accidents (19.1 %). Fall accidents and mild injuries had the lowest median age. Patients from outside Kathmandu Valley constituted 44.9 % of the cases. Only 12.1 % of the patients were admitted to the hospital.
Conclusion:Commonest head injuries are mild and superficial; and are caused by falls and road traffic accidents. Most head injury patients are children.

(Institute of Medicine, 2020) Pathak, Sunil; Acharya, Subhash P; Acharya, Pragya; Bhattarai, Binita
ABSTRACT
Introduction: An Intensive Care Unit (ICU) is an area where critically ill patients are admitted and the highest level of care is provided with close intensive monitoring and management. Clinical audit is a must to measure indicators of the quality of care in ICU and benchmarking outcome. The main aim of the study was to evaluate the profile of patients admitted to ICU and assess their outcome of two consecutive years.
Methods:A single-institutional, descriptive cross-sectional study was conducted on all adult patients admitted to the ICU of Tribhuvan University Teaching Hospital, Kathmandu, between April 2018 and April 2020 (Baisakh 2075 to Chaitra 2076).
Results: With an average of 1.98 admissions per day, a total of 1447 patients were admitted to TUTH ICU over the period of two years. A male preponderance was noted with a male to female ratio of 1.19:1. Most of the patients admitted were neurosurgical cases 429 (29.6%). A total of 884 (61%) were shifted out of ICU in stable condition while the overall mortality was 458 (31.6%).
Conclusion:This study shows that there is a higher severity of illness at admission as well as a comparatively high mortality rate. More number of patients were male, of age group of 15-65 years, with medical and neurosurgical conditions. This study of profile and outcome of patients admitted in ICU can serve as a quality indicator as well as evidence on which planning and policymaking can be based upon in the future.
