Section of General Surgery

Laparoscopic splenectomy has universal acceptance due to less morbidity and decreased incidence of per-operative and postoperative complication. It is not a popular procedure in Pakistan due to technical challenges. Here, we are presenting our experience of laparoscopic splenectomy for haematological disorders at Aga khan university hospital. A total of seven cases, underwent elective laparoscopic splenectomy for haematological disorders. The operative time was less than 3 hours with minimal blood loss with rapid and uneventful recovery.

Dermatofibrosarcoma Protuberans: An Unusual Case Of Neck Swelling, Naeem Sultan Ali, Maliha Kazi, Beena Umar, Mumtaz Jamshed Khan

Section of Otolaryngology, Head & Neck Surgery

Dermatofibrosarcoma protuberans (DFSP) is a relatively intermediate to low grade malignant tumour with high proclivity for local recurrence if excised inadequately. It is a locally aggressive tumour and despite sharing some histological features with fibrohistiocytic tumours, it tends to grow in a more infiltrative manner. We are reporting this rare tumour in a 30-year-old woman where the diagnosis of DFSP was confirmed histologically and by positive immunomarkers at immunohistochemistry.

Post-Traumatic Apexogenesis Of Immature Non-Vital Permanent Incisors, Robia Ghafoor

Section of Dental-Oral Maxillofacial Surgery

Injury to an immature permanent tooth may result in cessation of dentin deposition and root maturation leaving an open root apex and thin dentinal walls that are prone to fracture. Endodontic treatment is often complicated and protracted with an uncertain prognosis frequently resulting in pre-mature tooth loss. There are several advantages of promoting apexogenesis in immature teeth with open apices. It encourages a longer and thicker root to develop thus decreasing the propensity of long term root fracture. This case report highlights the role of Hertwig root sheath and dental papilla in continued root formation of immature permanent tooth, even …

Incidental Finding Of A Giant Aortic Root Aneurysm And Its Repair, Saulat H. Fatimi, Roheena Zainab Panni, Awais Ashfaq

Section of Cardiothoracic Surgery

The prevalence of aortic aneurysms is 3-4% in individuals more than 65 years. Age and haemodynamic factors play an important role in the development of aortic aneurysms. Most patients with aortic aneurysms are asymptomatic at the time of discovery. Thoracic aneurysms are usually found incidentally after chest radiographs or other imaging studies. The most common complications of thoracic aortic aneurysms are acute rupture or dissection. Some patients present with tender or painful nonruptured aneurysms. Patients are thought to be at increased risk for rupture and should undergo surgical repair on an emergent basis We document a case of a 66-year-old …

Following initial workup, cyst excision was carried out which revealed presence of fungal hyphae that was susceptible to Fluconazole therapy post operatively. The case points out how a pulmonary cyst can present in older children with symptoms of respiratory distress and mass effects.

A Comparative Analysis Of Toluidine Blue With Frozen Section In Oral Squamous Cell Carcinoma, Montasir Junaid, Moaz M. Choudhary, Zain A. Sobani, Ghulam Murtaza, Sadaf Qadeer, Naeem S. Ali, Mumtaz J. Khan, Anwar Suhail

Department of Surgery

Background:Surgical excision of the primary tumor with safe margins remains the mainstay of treatment for oral cavity squamous cell carcinoma (OSCC). The standard of care for assessment of intraoperative margins is frozen section histopathology. Unfortunately the facility is not available at most centers in limited resource countries. Toluidine blue, a metachromatic dye, has been well described in clinical identification of malignant and premalignant lesion in the oral cavity. Considering this we decided to explore intraoperative use of toluidine blue staining, in comparison with frozen sections, for the assessment of tumor-free margins.

Methods:

After obtaining clearance from the in-house ethical …

Asymptomatic Presentation Of Giant Bulla Of The Left Apical And Anterior Segment Of The Left Upper Lobe Of The Lung With Near Complete Atelectasis Of The Remaining Left Lung, Saulat H. Fatimi, Mahrukh Riaz, Hashim Muhammad Hanif, Marium Muzaffar

Section of Cardiothoracic Surgery

Giant bullae may be found in association with emphysema. They present as pockets of entrapped air which grow as the surrounding lung retracts away. As they do not take part in gas exchange and merely occupy space, their presence leads to severe impediment of mechanical ventilation in the adjacent lung parenchyma. Patients may present with dyspnoea, exercise intolerance and a feeling of pressure in the chest. The case of a 54 year old gentleman is presented, who was found to have a giant bulla occupying his left hemithorax on a routine chest X-ray. The patient remained asymptomatic despite the large …
