Intraductal papillary neoplasms (IPNs) of breast form a wide spectrum of pathological changes with benign intraductal papilloma occupying one end of the spectrum and papillary carcinoma at the other end. Intraductal papillomas are known to occur anywhere within the ductal system and are broadly classified into central and peripheral types. Intraductal papillary carcinoma is an uncommon ductal malignancy forming papillary structures, and these lesions characteristically lack the myoepithelial layer present in benign papillary neoplasms. Three basic patterns of IPNs are recognized on ultrasound - intraductal mass with or without ductal dilatation, intracystic mass and a predominantly solid pattern with the intraductal mass totally filling the duct. Benign papillomas are known to exhibit calcifications which tend to be extremely dense and coarse. IPNs are highly vascular tumours and have a propensity to bleed spontaneously. A distinct vascular pedicle is identified within the central core of IPNs, with branching vessels arborising within the mass. In an older age group, presence of a large solid component and evidence of spontaneous intracystic bleed are more suggestive of papillary carcinomas than benign papillomas. We have serially studied 42 cases of intraductal papillary neoplasms with sonomammography and mammography from 2001 to 2004.
Background: Gallstone disease known as cholelithiasis is the most common digestive surgical disorder and account for an important part of health care expenditure. Attempt was made to analyse the gallstone for typing depending upon the composition. Aims & objectives:The main objective of this study was to see the prevalence of different types of gallstone in Nepal and to correlate them with the clinical fi ndings. Results & conclusion:The most commonly involved age group for cholelithiasis (32.5%) is found to be 30-39 years with a female predominance (M: F=1:3.2). Cholelithiasis was found more commonly among non-vegetarian with the vegetarian: non-vegetarian ratio 1:9. Mixed type stone was found to be the most common type of stone comprising 78.75%, followed by cholesterol stone 12.5%, Brown pigment stone 7.5% and Black pigment stone 1.25%.
Introduction: Laparoscopic cholecystectomy is one of the most common operation performed. Though LC have become safer and easier at times it can be difficult. Difficult cases can result in prolonged operative time, bleeding, bile spillage, conversion to open technique and bile duct injury resulting in unplanned prolonged hospital stay, increase in estimated cost to the patients and for the surgeon it leads to increased stress during operation and time pressure to complete the operative list. . Identification of difficult cases has potential advantages for surgeons, patients and their relatives. We aim to develop and validate a scoring system to predict difficult LC preoperatively. Methods: Prospective study. History, physical examination, abdominal ultrasound and biochemical parameters were included to develop a scoring system. Hundred patients undergoing LC were included and preoperative scores were calculated preoperatively to predict difficult LC which was compared with operative assessment. Results: Sensitivity and specificity of the preoperative scoring for difficult case was 53.8 % and 89.2 % respectively with PPV of 63.64 % and NPV of 84.62%. Only three parameters (history of acute cholecystitis, gall bladder wall thickness and contracted gall bladder) were statistically significant to predict difficult LC individually. Area under ROC curve was 0.779 (95 % CI, 0.657-0.883). Conclusions: Preoperative scoring system can be used to predict difficult LC. Surgeons can plan operation based on predicted difficulty. Patients and relatives can be counselled preoperatively for the possibility of difficult operation, prolonged hospital stay and increased cost in predicted difficult case. Keywords: difficult cholecystectomy; laparoscopic cholecystectomy; symptomatic cholelithiasis.
Introduction: Acute pancreatitis is common clinical resentation. Gall stone disease and alcohol consumption are most common etiologies. Detection of biliary etiology is important in order to provide definite management in form of cholecystectomy to prevent further attacks. Sensitivity for abdominal ultrasound to detect cholelithiasis is decreased to 67–87% in presence of acute pancreatitis. Difference in biochemical investigations of acute biliary and non-biliary pancreatitis has been proposed to increase the suspicion of biliary etiology. Methods: Sixty patients admitted with diagnosis of acute pancreatitis from March 2012 to December 2012 were included in the study. The relation between etiology with age, sex, admission serum amylase and liver function test were evaluated. Results: Out of 60 patients 38 (63.33%) and 22 (36.66%) had biliary and non-biliary etiology respectively. Biliary pancreatitis was more common in females (25 vs. 3). Distribution of severity was comparable between both groups. Biliary pancreatitis group had significantly higher amylase level (3466.42 vs. 1987.5, p 0.003) whereas values of liver function test were higher in biliary pancreatitis though not statistically significant. Conclusions: A simple, rapid and accurate prediction of biliary etiology of acute pancreatitis can be provided by changes in biochemical parameters.

Laparoscopic inguinal hernia repair is still not the gold standard for repair although mesh implantation is unequivocally accepted as an integral part of any groin hernia repair. The aim of the study was to compare the results of anterior preperitoneal (APP) mesh repair with totally extra peritoneal (TEP) repair for inguinal hernias. The prospective study was conducted on 241 patients with 247 hernias (from January 2000 to June 2004). Anterior preperitoneal repair was done in 121 patients and 120 patients were subjected to TEP repair. Repair in both groups was done by using Prolene mesh of size 6x4 in. or 6x6 in. intraoperative and postoperative parameters and complications were recorded and the patients were followed up to 1 year post-surgery. For both unilateral and bilateral inguinal hernias, mean operative time was significantly more in patients of TEP repair as compared to APP repair (P<0.001) and significantly more patients had peritoneal tears in the TEP group (P<0.001). Patients undergoing TEP repair, however, had significantly less postoperative pain (P<0.05) and postoperative hospital stay (P<0.05) and return to work was significantly earlier is this group (P<0.01 and P<0.001). There was no difference in the recurrence rate between the two groups. Patients with inguinal hernias undergoing laparoscopic repair recover more rapidly, and have less incidence of postoperative pain. But it takes significantly more time to perform than APP repair and also the incidence of peritoneal tear is higher.
Context:Minimal access surgery (MAS) in children are common place and performed worldwide with gratifying results as the learning curve of the surgeon attains plateau. We share our experience of this technically evolving modality of surgery, performed at our setup over a period of 5 years. We also review and individually compare the data for commonly performed procedures with other available series. Author also briefly discuss potential advantages of MAS in certain debatable conditions performed quickly and with cosmesis as open procedure.Materials and methods:We performed 677 MAS in children aged between 7 days and 12 years. Five hundred and sixty-eight of these were Laparoscopic procedures and 109 were Video assisted thoracoscopic surgeries (VATS). In all laparoscopic procedures, the primary port placement was by the Hasson's open technique. We have used 5, 3 and 2 mm instruments. Our study include 259 inguinal hernia, 161 Appendectomies, 95 VATS for empyema, 51 orchiopexies, 49 diagnostic laparoscopy, 29 cholecystectomies, 22 adhesionlysis and other uncommonly performed procedures.Results:The ultimate outcome of all the performed procedures showed gratifying trend, the data of which are discussed in detail in the article. Conclusion: As we gained experience the operating time showed a decreasing trend, the complication rates and conversion rate also reduced. The advantages we came across were better postoperative appearances, less pain and early return to unrestricted activities.
Background: Early identification of severe acute pancreatitis is important for early stratification, goal directed fluid therapy, rationalizing level of care to improve outcome. Various clinical, laboratory and imaging scoring system has been used to identify severe acute pancreatitis with variable results. Recently a decision tree model was proposed using serum creatinine, serum lactate dehydrogenase and oxygenation index to predict severe acute pancreatitis. This system is easy and usable at our centre. Hence, we conducted the study to validate the decision tree model prospectively.Methods: Patients admitted with a diagnosis of acute pancreatitis were included in the study. Decision tree model was used to identify patients at high and low risk for severe acute pancreatitis. Sensitivity and specificity were calculated for prediction of the decision tree model.Results: Fifty-three patients were included in the study. Fourty-one (77.4 %) patients with mild acute pancreatitis, five (9.4 %) patients had moderately severe pancreatitis and seven (13.2 %) patients had severe acute pancreatitis. Sensitivity and specificity of decision tree model to predict severity of pancreatitis was 97.83%(95 % CI – 88.47% to 99.94%) and 71.43 % % (95 % CI – 29.04% to 96.33%) respectively with positive and negative predictable value of 95.74 % % (95 % CI – 87.45% to 98.64%) and 83.33 % % (95 % CI – 40.49% to 97.35%) respectively.Conclusions: Decision tree model with serum creatinine, lactate dehydrogenase, and oxygenation index is an easy and useful tool to predict patients at high risk of developing severe acute pancreatitis.Keywords: Acute pancreatitis; decision tree; severe acute pancreatitis.
