Endoscopic Ultrasound Guided Pancreatic Pseudocyst drainage experience at a tertiary care unit.

OBJECTIVE: To evaluate the clinical success, technical success and complications related to Endoscopic ultrasound (EUS) guided Pancreatic pseudocyst (PPC) drainage. METHODS: This retrospective study was conducted on the patients with symptomatic PPC who presented over a period of three years, between January 2015 and September 2018, at Endoscopic Suite of Surgical Unit 4, Civil Hospital, Karachi. Record was analyzed for demographic data, indications for the procedure, complications and success related to EUS guided drainage. Statistical analyses were performed using the SPSS Version 22. RESULTS: Total number of patients was 71. Mean age was 37.20 ± 17.27 years with a range of 6 to 68 years. Complications occurred in 12 (8.52%) patients, including stent migration (5/12), bleeding (4/12), infection (1/12), intra-abdominal abscess (1/12) and perforation (1/12). Technical success was achieved in 100% and clinical success in 97.1%. There was no procedure-related mortality. CONCLUSION: Pancreatic pseudocyst (PPC) is a known complication of acute as well as chronic pancreatitis which can have dreaded and appalling effects. In this part of the world with limited and scarce resources, EUS guided drainage of PPC is most feasible and rational with minimal complications, thus making it a front runner procedure.

Plastic stent migration in ERCP; a tertiary care experience.

OBJECTIVE: To evaluate the entire spectrum of endoscopic retrograde cholangiopancreatography procedure including site of stent migration, techniques of stent retrieval, success and complications. METHODS: The retrospective study was conducted at Dr Ruth Pfau Civil Hospital Karachi, and comprised data from January 2010 to January 2017of patients who underwent endoscopic retrograde cholangiopancreatography for the retrieval of stent migrated in the common bile duct, pancreatic duct or pancreatic pseudocyst or were found to have migrated stent during either stent removal or exchange and where attempts were made to remove the stent. A team of expert endoscopists had performed all the procedures. SPSS 17 was used for statistical analysis. RESULTS: There were 5700 procedures performed on 4800 patients. Pancreato-biliary stenting was done in 1229(21.56%) patients; 745(60.61%) with benign conditions and 484(39.38%) with malignant. Stent migration was found in 51(4.14%) patients; 30(58.8%) males and 21(41.2%) females. In terms of clinical presentation, right upper quadrant pain was the most common 9(17.6%). Technical success was achieved in all (100%) cases, with firstprocedure success in 45(88.2%). There was no complication or procedure-related mortality. CONCLUSIONS: In patients with stent migration, endoscopic retrograde cholangiopancreatography was found to be a safe and effective modality for stent retrieval.

Pancreas Divisum.

OBJECTIVE: To evaluate the complications, technical success, diagnostic evaluation and various endoscopic management options in patients with pancreas divisum. STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: Endoscopy Suite, Surgical Unit 4, Civil Hospital, Karachi, from January 2007 to December 2013. METHODOLOGY: All Endoscopic Retrograde Cholangio-pancreatography (ERCPs) procedure performed in patients with pancreas divisum were analyzed. Success was defined as having authentic diagnostic information or a successful endoscopic therapy for the condition. RESULTS: During the study period, 3600 patients underwent 4500 ERCPprocedures. Pancreas divisum was found in 17 patients (0.47%); 7 ERCPs (41.2%) were performed for diagnostic and 10 (58.8%) for therapeutic purposes. Sixteen (94.1%) had complete PD and one (5.9%) had incomplete PD. Male and Female ratio was 1:1.83 with a mean age of 26.3 years and median symptom duration of 11 months. Atotal of 23 procedures were performed in 17 patients; 2 had ERCP done thrice, 2 underwent the procedure twice, while the rest had single procedure done. Six (35.3%) patients had chronic pancreatitis, 7 (41.2%) had acute recurrent pancreatitis and 4 (23.5%) had acute pancreatitis. Endoscopic minor papillotomy was performed. There was no procedure-related mortality. ERCPaffected management in 88.2% (15/17 procedures). CONCLUSION: ERCPis a safe and feasible procedure for pancreas divisum patients.

Guidelines on gastroesophageal reflux disease.

Gastroesophageal reflux disease (GERD) is the most common acid-related disorder encountered during clinical practice in Pakistan and is associated with significant impairment of health-related quality of life. A number of guidelines and recommendations for the diagnosis and management of GERD have been published in different countries, but a Pakistani accepted directive by the standards of evidence-based medicine is still lacking. Our aim was to create an understanding of the natural history and presentations of reflux disease; evaluating possible treatment options available for the patients with complex and uncomplicated reflux ailments with the development of current and up to date evidence based endorsement, relevant to the needs of Pakistani health care providers in order to treat oesophageal manifestations of GERD. In order to make such guidelines, a comprehensive literature search was conducted with pertinent evidence reviewed, and quality of relevant data assessed. The resultant conclusions were based on the best available evidence and expert opinion of the authors of technical review panel.

Frequency and risk factors in the post-ERCP pancreatitis in a tertiary care centre.

OBJECTIVE: To evaluate the frequency and associated factors in the post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. STUDY DESIGN: Cross-sectional analytical study. PLACE AND DURATION OF STUDY: Endoscopy Suite of Surgical Unit IV, Civil Hospital, Karachi, from December 2009 to November 2010. METHODOLOGY: Patients undergoing ERCP were included. Patients who had presented with pancreatitis or raised amylase levels before procedure or patients who had previous history of surgery on the biliary or pancreatic systems were excluded from the study. Pearson chi-square and Fisher's exact test were used for qualitative data and t-test for quantitative data. Significance was taken as p ² 0.05. Odds ratio was calculated for the qualitative data using 95% confidence interval. RESULTS: Age of the study population ranged from 9 to 90 years (mean age 46.5 ± 14.94 years, median 45 years). Male to female ratio was 1:1.87. Pancreatitis was seen in 18 patients (3.6%), mild in 15 (3%), moderate in one (0.2%) and severe in 2 (0.4%). Mean amylase level at 4 hours and 24 hours was 280.93 ± 539.13 and 168.83 ± 338.34 respectively. Pancreatitis was seen in 15/326 (4.6%) females and 3/174 (1.72%) males. Statistically significant increased risk for pancreatitis was seen in difficult cannulation (9.8%, p = 0.006), prolonged cannulation time (7.6 minute, p = 0.002), pancreatic duct cannulation (13.7%, p = 0.001) and pancreatic duct contrast injection (13.4%, p < 0.001). CONCLUSION: The frequency of post-ERCP pancreatitis was 3.6%. Difficult cannulation, pancreatic duct cannulation, pancreatic duct contrast injection and balloon sphincteroplasty were associated with higher frequency of post-ERCP pancreatitis. Reuse of ERCP accessories poses no additional risk to the frequency of pancreatitis.

Pseudoxanthoma elasticum and nephrolithiasis: a rare association.

Pseudoxanthoma elasticum (PXE) is a multi-systemic, genetic disorder of connective tissue characterized by progressive calcification and fragmentation of elastic fibers in skin, retina and cardiovascular system. A young patient reported to urologist in emergency with azotemia secondary to acute bilateral obstructive uropathy. Upon successful management, he was found to have full-blown skin and eye manifestations and was evaluated thoroughly regarding extent and potential systemic complications of Pseudoxanthoma elasticum.
