Operating room black box: GIMMICK or a patient safety tool?

The Operating Room Black Box (ORBB) is a relatively recent technology that provides a comprehensive solution for assessing technical and non-technical skills of the operating team. Originating from aviation, the ORBB enables real-time observation and continuous recording of intraoperative events allowing for an in-depth analysis of efficiency, safety, and adverse events. Its dual role as a teaching tool enhances transparency and patient safety in surgical training. In comparison to traditional methods, like checklists that have limitations, the ORBB offers a holistic understanding of clinical and non-clinical performances that are responsible for intraoperative patient outcomes. It facilitates systematic observation without additional personnel, allowing for review of numerous surgical cases. This review highlights the potential benefits of the ORBB in enhancing patient safety, its role as a surgical training tool, and addresses barriers especially in resource-constrained settings. It signifies a transformative step towards global surgical practices, emphasizing transparency and improved surgical outcomes.

Need For A National Cancer Registry In Pakistan: Challenges And Way Forward.

The incidence of cancer is rising globally at a remarkable rate. According to the global cancer Observatory, the total number of cases in Pakistan were 178,388 in 2020; and these figures were provided by the Punjab Cancer Registry which represents the population of Lahore and some parts of central Punjab. Considering the overall 220 million population, these figures are severe underestimation of the true cancer burden in Pakistan. Unfortunately, several attempts at establishing a national cancer registry in the country have failed in the past. Resource limitations, including funds, manpower and infrastructure, and the lack of interest on the part of the governments are behind the failure of the establishment of a national cancer database. There is a dire need for establishing a national cancer registry to understand the actual burden of disease, and to implement a national action plan for cancer prevention, and management strategies to control the growing epidemic.

Volume and flow modulation strategies to mitigate post-hepatectomy liver failure.

Introduction: Post hepatectomy liver failure is the most common cause of death following major hepatic resections with a perioperative mortality rate between 40% to 60%. Various strategies have been devised to increase the volume and function of future liver remnant (FLR). This study aims to review the strategies used for volume and flow modulation to reduce the incidence of post hepatectomy liver failure. Method: An electronic search was performed of the MEDLINE, EMBASE and PubMed databases from 2000 to 2022 using the following search strategy "Post hepatectomy liver failure", "flow modulation", "small for size flow syndrome", "portal vein embolization", "dual vein embolization", "ALPPS" and "staged hepatectomy" to identify all articles published relating to this topic. Results: Volume and flow modulation strategies have evolved over time to maximize the volume and function of FLR to mitigate the risk of PHLF. Portal vein with or without hepatic vein embolization/ligation, ALPPS, and staged hepatectomy have resulted in significant hypertrophy and kinetic growth of FLR. Similarly, techniques including portal flow diversion, splenic artery ligation, splenectomy and pharmacological agents like somatostatin and terlipressin are employed to reduce the risk of small for size flow syndrome SFSF syndrome by decreasing portal venous flow and increasing hepatic artery flow at the same time. Conclusion: The current review outlines the various strategies of volume and flow modulation that can be used in isolation or combination in the management of patients at risk of PHLF.

Surgical and Oncological Outcomes of Hepatic Resection for Hepatocellular Carcinoma: Report from a Low Volume Centre in a Developing Country.

OBJECTIVE: To review the surgical and oncological outcomes of patients who underwent hepatic resection for hepatocellular carcinoma (HCC). STUDY DESIGN: Cohort study. PLACE AND DURATION OF STUDY: Department of Surgery of the Aga Khan University Hospital Karachi, from 2008 to 2019. METHODOLOGY: Consecutive patients who underwent hepatic resection for HCC at the Hospital were included. The data were collected and analysed on aspects including demographics, liver function status, tumour characteristics, perioperative management, and surgical and oncological outcomes. Survival analyses were performed using the Kaplan-Meier method, and log-rank test was applied to determine the influence of variables on overall and disease-free survival. RESULTS: A total of 59 patients underwent hepatic resection for HCC during the study period including 38(64%) males. The majority of the patients had a single lesion (88%), unilobar disease (95%), underlying cirrhosis (75%) and BCLC stage B (73%). Major hepatic resection was performed in 27(46%) patients. The mean duration of surgery was 288+101 minutes and the mean estimated blood loss was 986+637 mls. Postoperative complications developed in 22(37%) patients including surgical complications in 11(19%), liver decompensation in 4(7%) and systemic complications in 9(15%) patients. The overall 30-day mortality was 7%. With a mean follow-up of 2.8 years, disease recurrence was documented in 25(42%) patients and the median overall survival was 45 months. CONCLUSION: Hepatic resection for HCC is an effective treatment option in this setup. Despite low volumes, surgical and oncological outcomes of hepatic resection for HCC were comparable to the international standards. KEY WORDS: Hepatocellular carcinoma, Liver resection, Cirrhosis.

Prospective comparison of single encounter versus distributed laparoscopic training in novice learners: A controlled trial.

BACKGROUND: The traditional model of teaching surgical skills on "real" patients using graded responsibility is being seriously questioned, and there is a paradigm shift toward exploiting simulators. There is a lack of clarity on the impact of using simulation as a teaching strategy in novice learners. The purpose of our study was to determine if the number and duration of training sessions influence the acquisition and retention of laparoscopic skills in naïve learners. There are some data to suggest that distributed training programs might have better outcomes, but the results are inconclusive. We designed a controlled trial at Aga Khan University, Karachi, with the hypothesis that students trained using the distributed method may have enhanced learning outcomes. MATERIALS AND METHODS: 100 medical students were assigned in a 1:1 ratio to one of two groups. Group A underwent a single orientation and supervised practice session of 3 h duration. Group B underwent distributed teaching with three learning sessions of 1 h each spread over 3 consecutive weeks. Participant scores were analyzed before and after the intervention and at 3- and 6-month intervals using repeat measures of ANOVA. RESULTS: Pretest and immediate posttest scores were comparable between the two groups. The 3-month interval test showed significantly higher scores in Group B (difference = -2.90, P < 0.001). The 6-month interval test showed no differences in scores between the two groups (P = 0.178). CONCLUSIONS: Distributed teaching resulted in significantly enhanced scores at 3-month assessment. However, similar scores at 6 months suggest the need for repeated intervention.

Paraganglioma of common bile duct: A case report.

Paragangliomas are rare tumours derived from the neural crest cells. Most common site for these tumours is the adrenal medulla, where they are called as pheochromocytomas. Biliary system is an extremely uncommon site for extra-adrenal paraganglioma. We report the case of a 55 year old female who presented with one-month history of jaundice and right upper quadrant discomfort. Imaging showed a well-defined rounded mass at porta hepatis with arterial enhancement causing compression over the proximal common bile duct, resulting in moderate intrahepatic biliary dilatation. The patient underwent radical excision of common bile duct and roux-en-y hepaticojejunostomy. Final histopathology confirmed paraganglioma. Approximately 10% of patients may present with extra-adrenal disease, but biliary paraganglioma are extremely rare. Only few cases have been reported in literature and the management usually involves the surgical excision. Being a rare disease, a high index of suspicion is important for diagnosis of paraganglioma at such an uncommon location.

Pancreatic gastrointestinal stromal tumour with liver metastasis five years after Whipple's procedure: A rare case with management.

Pancreatic gastrointestinal tumour is an unusual primary tumour of the pancreas. A 31-year-old male came to the clinic with jaundice and weight loss. Cross-sectional imaging showed a mass in the pancreatic uncinate process. Image-guided biopsy revealed gastrointestinal stromal tumour, so pancreaticoduodenectomy was performed, followed by adjuvant Imatinib. The patient had oligo-metastasis in the liver five years post-surgery and underwent liver resection. This is an unusual case where a pancreatic GIST presented with metastasis while on adjuvant treatment. Hepatectomy and multimodal therapy increases the survival if the disease is confined to the liver.

Is age just a number or does it really affect the surgical and oncological outcomes after pancreatoduodenectomy?

OBJECTIVE: To review the impact of age on perioperative and postoperative outcomes in patients following pancreaticoduodenectomy. METHODS: The retrospective study was conducted at the Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan, and comprised data from January 2014 to December 2018 of all patients who underwent pancreatoduodenectomy. Postoperative morbidity and oncological outcomes were compared between patients aged ≤60 years in group A and those aged >60 years in group B. Data was analysed using SPSS 20. RESULTS: Of the 161 patients, 103(64%) were males and 58(36%) were females. There were 117(73%) patients in group A; 72(61.5%) males and 45(38.5%) females with an overall mean age of 46±11 years. The remaining 44(27%) were in group B; 31(70.5%) males and 13(29.5%) females with an overall mean age of 67±05 years. The most common pathology was adenocarcinoma 130(81%), commonest site was periampullary 85(53%) and the most common pancreatic reconstruction technique employed was pancreaticogastrostomy 110(68%). Patients in group B had significantly higher comorbidities compared to those in group A (p<0.05). Estimated blood loss during surgery was significantly higher in group B (p=0.004). There was no significant difference in overall morbidity (p=0.856), reoperation (p=1.000), 30-day readmission rate (p=0.097), 90-day mortality rate (p=0.324)) and overall survival (p=0.551) between the groups. CONCLUSIONS: Pancreatoduodenectomy could be performed in the elderly with comparable morbidity and oncological outcomes as younger patients. Comorbid conditions remained higher in elderly patients and preoperative optimisation may help improve postoperative outcomes.

Mandatory multidisciplinary management of hepatocellular carcinoma: Need of the hour in a country with high prevalence of hepatitis C virus infection.

Hepatocellular carcinoma is the sixth common cancer diagnosed and fourth leading cause of cancer-related deaths worldwide. Its incidence is on rise due to increasing prevalence of chronic hepatitis C virus infection. Pakistan is ranked second in countries burdened by hepatitis C virus in the world. Management of hepatocellular carcinoma is complex as it develops on the back of liver cirrhosis, and the risk of mortality is an accumulation of both tumour-related factors as well as liver decompensation. A multidisciplinary tumour board is an ideal approach to improve the outcomes of hepatocellular carcinoma since this ensures assimilation of input from a diverse group of care-providers, including hepatobiliary and transplant surgeons, gastroenterologists, interventional radiologists, oncologists and palliative care specialists. A multidisciplinary tumour board provides tailored approach to individual cases in a timely fashion to avoid treatment delays and communication gaps to improve the overall outcomes.

Mentorship in surgical training: Where do we stand?

Mentorship in medicine aims at professional and personal development of trainees in the early stages of their careers. It is more popular in surgical subspecialties since transfer of technical skills is an integral part of surgical training, which makes it distinct compared to other specialties. Effective mentoring in surgery plays a crucial role in academic success, professional development, career guidance and personal growth of residents, and provides guidance and support to mentees to excel in their respective fields, and increases the likelihood of success by enhancing motivation with positive impact on burnout among residents. Efforts have been made by accreditation bodies around the world to implement formal mentorship in residency programmes. Unfortunately, there is lack of formal mentorship at the level of postgraduate medical education in Pakistan, and the evidence to identify potential obstacles is scarce from this part of the world.

Apprenticeship to simulation - The metamorphosis of surgical training.

Surgery is a dynamic specialty and surgical competencies are a combination of both technical and non-technical skills. After the inception of the art of surgery, surgical education and training has undergone incredible evolution. The first model of surgical training was introduced in the 19th century and is known as the 'apprenticeship model', followed by the famous 'Halstedian' model. However, a report by the Institute of Medicine challenged the teaching institutions to formulate alternative methods of surgical education to ensure patients' safety and to reduce the fear among patients of them being practised on. Teaching surgical skills outside the operating room to ensure patient safety has laid the foundation of simulation-based training in surgical education. More recently, the focus of surgical training and residency has shifted to competency and outcome-based models. The current review article was planned to describe the evolution and transformation of surgical training over time.

Pancreaticoduodenectomy: Outcomes of a complex surgical procedure from a developing country.

BACKGROUND: Pancreaticoduodenectomy (PD) plays an integral part in the management of pancreatic, periampullary and duodenal cancers, along with a few other pathologies of this region. Despite advances in surgery PD continues to have significant morbidity and noteworthy mortality. The aim of this study is to provide an in-depth report on the patient characteristics, indications and the outcomes of PD) in a tertiary cancer hospital in Pakistan. MATERIALS AND METHODS: The study population included patients who underwent PD between January 1, 2014 and march 31, 2019, at Shaukat Khanum Memorial Cancer Hospital and Research Center (SKMCH&RC) in Pakistan. The data was retrospectively analyzed from the Hospital Information System (HIS), which is a prospectively maintained patient electronic database of SKMCH&RC. Patient characteristics, procedural details and post-operative outcomes according to internationally accepted definitions were reported. RESULTS: A total of 161 patients underwent PD at our hospital in the study period at a median age of 53 years, ranging from 19 to 78 years. 62% of the patients were males while 37% were females. Jaundice was the most common presenting symptom (64.6%), followed by abdominal pain (26.7%). PD with pancreaticogastrostomy was performed in 110 patients (68.3%), while pancreaticojejunostomy was performed in the rest of the cohort. Surgical site infection (SSI) was observed in 64 patients (40%). The incidence of Pancreatic Fistula grade C based on the International Study Group on Pancreatic Fistula (ISGPF) definition was 7.45% (n = 12). The 30 days mortality rate was 3.1%. Median survival of the cohort was 21 ±1.13 months and disease-free survival was 16±2.62 months. CONCLUSION: PD can be performed with acceptable morbidity and mortality in a resource constrained country, as long as it is undertaken in a high-volume center. This is in keeping with data published from other well-reputed international centers.

Surgical and oncological implications of aberrant arterial anatomy in patients undergoing pancreatoduodenectomy.

Whipple's pancreatoduodenectomy is a complex surgical procedure and any aberrant arterial anatomy may have serious surgical implications. The objective of our study was to analyse the frequency of aberrant hepatic artery and compare the outcomes in patients with normal anatomy. Clinical data and computed tomography scans of 45 consecutive patients who underwent Whipple's procedure from 2007 to 2016 were reviewed. Group 'A' included patients with aberrant hepatic artery while group 'B' with normal anatomy. Aberrant hepatic artery was present in 11 (24%) patients and type V was the most common variant (n=5, 45%). Morbidity rate in group A was 82% and group B was 62% (p= 0.288), while 30-day mortality rate was 18% and 9% respectively (p=0.582). There was no difference in the oncological clearance in both the groups. Aberrant hepatic artery does not seem to influence the morbidity, mortality and tumour resection margins in patients undergoing Whipple's procedure.

Isolated gallbladder injury from blunt abdominal trauma: A rare co-incidence.

Gallbladder injury resulting from blunt abdominal trauma is a rare entity and generally associated with other intra-abdominal injuries. Incidence of isolated gallbladder injury has not been reported yet. The most common mechanism of injury reported is road traffic accident. Diagnosis is usually made on imaging as clinical presentation may vary from no symptoms to peritonitis due to extravasation of bile in the abdominal cavity. Cholecystectomy is the treatment of choice and minimally invasive approach can be considered in haemodynamically stable patients.

Extended resection for xanthogranulomatous cholecystitis mimicking gallbladder carcinoma: Cases and review of diagnostic approach.

Xanthogranulomatous cholecystitis is a rare variant of chronic cholecystitis, which can involve adjacent organs including liver, colon and duodenum mimicking gallbladder cancer. Preoperative and intraoperative differentiation of xanthogranulomatous cholecystitis from gallbladder cancer is often difficult and the final diagnosis is made on histopathology of the resected specimen. We hereby report four cases of xanthogranulomatous chol ec ystitis w hich were misdiagnosed as cases of advanced gallbladder cancer based on presentation and radiological findings and underwent radical resections but the final histopathology was a diagnostic surprise. Xanthogranulomatous cholecystitis is still a diagnostic challenge as no single modality has been helpful to diagnose this entity till date. Radical resection seems justified in patients who present with the features mimicking gallbladder cancer.

Cost effectiveness of Glove Endobag in Laparoscopic Cholecystectomy: Review of the available literature.

Laparoscopic cholecystectomy is the most common procedure performed worldwide and remains the gold standard for symptomatic gallstones. The most common complication obser ved during this procedure is gallbladder perforation resulting in spillage of stones and bile into peritoneal cavity. In order to avoid such complications, gallbladder is commonly extracted in an endobag. The current literature review was conducted to assess the efficacy and cost-effectiveness of glove endobags. PubMed and Google Scholar databses were searched to find relevant studies from January 1990 to December 2017. Search terms used were 'glove endobag' and 'laparoscopic cholecystectomy'. Literature suggests glove endobag is an effective and comparatively inexpensive compared to commercially prepared endobags.

Short-term outcomes after hepatic resection : perspective from a developing country.

OBJECTIVE: To review the early outcomes of hepatic resection at our hospital. METHODS: This study was conducted at the Aga Khan University Hospital, Karachi, from January 2008 to December 2015, and comprised patients who underwent hepatic resection. We analysed the pathology, magnitude of hepatic resection and short-term outcomes in the patients. Mean and standard deviations were used to describe categorical data whereas frequencies and proportions to describe quantitative data. Univariate analysis was done to look at the factors associated with morbidity, mortality and blood loss during surgery. SPSS 19 was used for data analysis. RESULTS: Of the 75 participants, 43(57.3%) were males and 32(42.7%) were females. The overall mean age was 52±14 years. Besides, 37(49.3%) patients underwent hepatic resection for underlying hepatocellular carcinoma, with 30(81%) of them being cirrhotic. Major hepatectomy (>3 segments) was performed in 30(40%) patients. Postoperative complications were observed in 30(40%) patients including postoperative liver failure in 3(4%) patients. The presence of one or more co-morbid conditions had a statistically significant association with postoperative morbidity (p=0.018). Mortality rate at 30days and 90days were 3(4%) and 5(6.7%), respectively. DISCUSSION: Morbidity, mortality and blood loss were comparatively higher in cirrhotic patients.
