RESUMO

The recent resurgence of the Crimean-Congo hemorrhagic fever (CCHF) in Pakistan's Balochistan province has significantly impacted both the medical community and the general population. Initially perceived as a concerning development, the situation has deteriorated, culminating in the infection and mortality of healthcare workers directly engaged in managing this virulent outbreak. This critical situation necessitates an urgent and collective response, transcending national boundaries to involve the international healthcare community.

RESUMO

This article addresses the significant issue of gender bias in leadership roles within the realm of general surgery, with a particular focus on the South Asian context. The persistence of cultural norms, entrenched gender stereotypes, and discriminatory practices in this region significantly limits the opportunities available to female surgeons. It calls on all stakeholders, including medical institutions, governing bodies, and surgeons, to take an active role in eliminating gender bias and fervently supporting diversity and inclusivity in leadership positions. By doing so, it argues, we can create a more equitable and promising future for the field of general surgery in South Asia.

RESUMO

Background: Irritable bowel syndrome (IBS) is a functional gastrointestinal (GI) disorder and is closely linked to stress. Psychiatric morbidities such as anxiety and depression are common in IBS. Long-term follow-up studies on anxiety and depressive symptoms in IBS and the impact of treatment are lacking in the Indian scenario. Aims: This study aimed to assess the various subtypes of IBS according to the Rome IV criteria, assess anxiety and depressive symptoms in patients with IBS at baseline and also at various phases of follow-up over one year, and see the impact of the treatment of both IBS and associated anxiety and depressive symptoms if present, in the severity of IBS and other psychiatric symptoms. Materials and Methods: Patients with IBS, aged between 18 and 65 years, were enrolled for the study. Subtypes and severity of IBS were assessed. Anxiety and depressive symptoms were assessed by the Hamilton Rating Scale for Anxiety (HAM-A) and the Hamilton Rating Scale for Depression (HAM-D), respectively. The patients were treated with conventional treatment of IBS with concomitant treatment of anxiety and depressive symptoms and were followed up for 1 year. Results: Thirty-seven patients completed a 1-year follow-up. The mean age was 38.4 ± 11.6 years. The majority were males (81%), and IBS-D (84%) was the most common subtype. Stressful life events (67.6%) and chronic stressors (64.9%) were present in the majority of the patients. The patients had moderate-to-severe anxiety at baseline (HAM-A score 27.8 ± 6.4) and moderate-to-severe depression at baseline (HAM-D score 19.7 ± 6.6). The improvement over 1 year was statistically significant (P = 0.000, two-tailed). A positive correlation between the severity score of IBS and HAM-D (r = 0.604) and HAM-A (r = 0.536) scores was present. Conclusion: There is a high prevalence of anxiety and depression in patients with IBS. With adequate treatment of both IBS and concomitant anxiety-depressive symptoms, there is a significant decrease in the severity of IBS, anxiety, and depression.

RESUMO

Desmoplastic small round cell tumor (DSRCT) is a rare, highly aggressive malignancy predominantly affecting adolescents and young adults. We report a case of multifocal DSRCT in an 11-year-old male who presented with complaints of unilateral forehead swelling, proptosis, and ophthalmoplegia for four months along with abdominal pain and dysphagia for six months. A whole-body computed tomography revealed widespread lesions in the skull, orbit, thorax, and abdomen with local infiltration. Ultrasound-guided biopsy of the forehead lump was performed. Based on histopathological and immunohistochemical investigations, it was diagnosed to be a DSRCT with multifocal presentation. The patient underwent chemo-radiation but unfortunately succumbed to neutropenic sepsis and renal failure. DSRCT is a very rare, highly aggressive malignancy with an extremely poor prognosis. Orbital presentations are even rarer, with less than 10 such cases currently described in English medical literature.

RESUMO

INTRODUCTION AND IMPORTANCE: Intraductal papillary neoplasm of the bile duct (IPNB) is a rare neoplasm, mostly found in patients from far Eastern areas where hepatolithiasis and clonorchiasis are endemic. Very few cases are reported from India. CASE PRESENTATION: We present a case of recurrent cholangitis in a 59-year-old male, initially suspected to have IPNB based on preoperative imaging. Confirmation occurred intraoperatively, with mucin-filled bile ducts and papillary lesions in the resected hepatic duct. Treatment included left hepatectomy, extrahepatic bile duct excision, and Roux-en-Y hepaticojejunostomy. Histopathology indicated invasive pancreatobiliary-type IPNB with clear margins. The patient experienced post-hepatectomy hepatic insufficiency and superficial incisional surgical site wound infection, managed conservatively. Discharge occurred on postoperative day 21, with satisfactory recovery at the 16-month follow-up. CLINICAL DISCUSSION: IPNB is recognized as the biliary equivalent of intraductal papillary mucinous neoplasm, as these two conditions exhibit multiple commonalities in terms of clinical and histopathological characteristics. The unique aspect of our case lies in the intricacies associated with its diagnosis. Initially, imaging modalities did not yield a definitive characterization of the lesion. Notably, the endoscopist misinterpreted mucin expression emanating from the papilla as purulent material, primarily due to the patient's concurrent cholangitis. Subsequent repetitions of both CT scan and MRI provided some valuable insights that contributed to the diagnostic clarity of the IPNB. CONCLUSION: In cases of symptoms like biliary obstruction with bile duct dilation, wall nodules, papillary/solid-cystic masses, and upstream-downstream dilation, IPNB should be considered. Striving for R0 resection is crucial for enhanced long-term patient survival.

RESUMO

BACKGROUND: Diagnosing pancreatic lesions, including chronic pancreatitis, autoimmune pancreatitis, and pancreatic cancer, poses a challenge and, as a result, is time-consuming. To tackle this issue, artificial intelligence (AI) has been increasingly utilized over the years. AI can analyze large data sets with heightened accuracy, reduce interobserver variability, and can standardize the interpretation of radiologic and histopathologic lesions. Therefore, this study aims to review the use of AI in the detection and differentiation of pancreatic space-occupying lesions and to compare AI-assisted endoscopic ultrasound (EUS) with conventional EUS in terms of their detection capabilities. METHODS: Literature searches were conducted through PubMed/Medline, SCOPUS, and Embase to identify studies eligible for inclusion. Original articles, including observational studies, randomized control trials, systematic reviews, meta-analyses, and case series specifically focused on AI-assisted EUS in adults, were included. Data were extracted and pooled, and a meta-analysis was conducted using Meta-xl. For results exhibiting significant heterogeneity, a random-effects model was employed; otherwise, a fixed-effects model was utilized. RESULTS: A total of 21 studies were included in the review with four studies pooled for a meta-analysis. A pooled accuracy of 93.6% (CI 90.4-96.8%) was found using the random-effects model on four studies that showed significant heterogeneity ( P <0.05) in the Cochrane's Q test. Further, a pooled sensitivity of 93.9% (CI 92.4-95.3%) was found using a fixed-effects model on seven studies that showed no significant heterogeneity in the Cochrane's Q test. When it came to pooled specificity, a fixed-effects model was utilized in six studies that showed no significant heterogeneity in the Cochrane's Q test and determined as 93.1% (CI 90.7-95.4%). The pooled positive predictive value which was done using the random-effects model on six studies that showed significant heterogeneity was 91.6% (CI 87.3-95.8%). The pooled negative predictive value which was done using the random-effects model on six studies that showed significant heterogeneity was 93.6% (CI 90.4-96.8%). CONCLUSION: AI-assisted EUS shows a high degree of accuracy in the detection and differentiation of pancreatic space-occupying lesions over conventional EUS. Its application may promote prompt and accurate diagnosis of pancreatic pathologies.

RESUMO

INTRODUCTION AND IMPORTANCE: Pediatric hepatic tumors present diagnostic challenges due to diverse clinical presentations and limited patient communication. Elevated serum alpha-fetoprotein (AFP) levels, often associated with hepatoblastoma, can occur in various hepatic conditions, adding complexity to diagnosis. This report emphasizes the importance of comprehensive assessment and integrated interpretation in such cases. CASE PRESENTATION: We present a rare case of a 1-year-old female child with abdominal swelling and hepatomegaly. Imaging revealed a hypodense hepatic lesion with punctate calcifications. Initial biopsy suggested mesenchymal hamartoma, but subsequent biopsy confirmed hepatoblastoma, highlighting the diagnostic complexity. CLINICAL DISCUSSION: Hepatoblastoma is the most common pediatric liver tumor, typically presenting with nonspecific symptoms. Serum AFP levels are elevated, aiding diagnosis. Imaging reveals heterogeneous, hypervascular masses. Treatment includes surgery and chemotherapy. Mesenchymal hamartoma is a rare benign tumor with variable symptoms and imaging features, emphasizing the need for histopathological confirmation. This case underscores the importance of a comprehensive diagnostic approach. CONCLUSION: Diagnosing pediatric hepatic tumors requires an integrated assessment of clinical, laboratory, and imaging findings. Confirmatory biopsies are essential, as demonstrated by this case, where an initial diagnosis of mesenchymal hamartoma was revised to hepatoblastoma. Collaborative, multidisciplinary approaches are crucial for accurate diagnosis and effective therapeutic planning, offering hope for improved outcomes in these complex cases.

RESUMO

INTRODUCTION AND IMPORTANCE: Anorectal melanoma is a rare and aggressive malignancy that can be difficult to diagnose due to its nonspecific presentation. CASE PRESENTATION: We present a case of a 69-year-old woman who presented with painful defecation, bleeding per rectum, and a mass coming out of her anal opening. The initial differential diagnosis included hemorrhoids, rectal polyp, or a malignant lesion of the rectum. However, histopathological evaluation following transanal excision of the rectal mass revealed mucosal melanoma in the anorectal region. Further investigation showed no evidence of locoregional or distant metastasis. CLINICAL DISCUSSION: Surgery remains the primary treatment option for anorectal melanoma, but complete resection is often not feasible, leading to high rates of local recurrence and distant metastasis. The incidence of metastatic disease at the time of presentation is high, and a multidisciplinary approach is necessary to manage these patients. Currently, standard systemic therapies used for cutaneous melanoma are the mainstay of treatment for metastatic anorectal melanoma, but there is a need for further research to develop tailored treatment strategies. CONCLUSION: Our case report highlights the importance of considering anorectal melanoma in the differential diagnosis of patients presenting with anorectal symptoms. It emphasizes the need for a multidisciplinary approach to managing this rare malignancy. Early diagnosis, a multidisciplinary approach, and ongoing research into more effective treatments are crucial for improving outcomes for patients with anorectal melanoma.

RESUMO

INTRODUCTION AND IMPORTANCE: Gastric neuroendocrine tumors (NETs) are rare neoplasms that originate from enterochromaffin cells in the gastric mucosa and pose a diagnostic dilemma due to their non-specific presentation. CASE PRESENTATION: We present a 79-year-old woman, who came with complaints of abdominal pain associated with loss of pain and appetite. Although on the first look multiple differentials could be listed, upon complete evaluation she was diagnosed to have type III Gastric NET. Histopathology and immunohistochemistry allowed diagnostic confirmation of the disease along with strong clinical suspicion. The patient however succumbed to the illness due to advanced disease and lack of established protocol for its management. CLINICAL DISCUSSION: The treatment of Gastric NETs primarily involves surgical resection of the tumor and is especially helpful in type I and II cases. For advanced metastatic type III NETs, lines of therapy have not been established although surgical resection can be done if the majority (∼90 %) of the tumor is resectable. Patients should be given a choice in decision making and newer drug therapies should always be considered. CONCLUSION: Since gastric NETs are a rarer cause of abdominal pain, it can often be overlooked in favor of other, more common differentials. One should be aware of this disease and the newer diagnostic methods to have any sort of clinical suspicion when presented with such a scenario. The management of the condition although not been established, novel therapies should be considered if the tumor is not resectable.

RESUMO

PURPOSE: The purpose of this study is to review our experience in patients who underwent re-operation for delayed biliary complications after choledochal cyst (CDC) excision. METHODS: All the patients who underwent re-operation. for delayed biliary complications after CDC excision between August 2007 and July 2020 were included in this retrospective study. The outcomes of these patients were compared with those who underwent primary surgery (CDC excision) at our institution. RESULTS: Of the total 40 patients with delayed biliary complications, 25 (62.5%) were female. Thirty-seven (92.5%) patients had a history of cholangitis. The median interval between CDC excision and the reoperation was 70 (4-216) months. The median duration of symptoms before reoperation was 12 (2.5-84) months. Re-do hepaticojejunostomy and direct hepaticojejunostomy were performed in 34 and in 6 patients respectively. Median operative time and blood losses were 219 min and 150 ml respectively. The median postoperative stay was 9 days. Postoperative complications developed in 10 (25%) patients. There was no operative mortality. Over a median follow-up of 71 months, a satisfactory outcome was achieved in 86% of patients. Restricture and intrahepatic stones developed in three and two patients respectively. Incidence of type IV cyst, cholangitis before operation, and operative blood loss were significantly more in the re-operative group. Clinical outcomes like the incidence of recurrent cholangitis, re-stricture, and postoperative hospital stay were comparable between the two groups. CONCLUSION: Surgery affords excellent results for majority of the patients with delayed biliary complications after CDC excision. Type IV cysts are more commonly associated with the development of delayed biliary complications.

RESUMO

BACKGROUND: The literature on predictors for postoperative complications after Frey procedure (FP) is sparse. The aim of this study is to report our experience with 90-day complications of FP and predictors for complications. METHODS: All patients with chronic pancreatitis (CP), who underwent a FP between August 2007 and July 2021, were retrospectively reviewed. Univariate and multivariate analysis were used to identify predictors of 90-day morbidity and mortality. RESULTS: Of the total 270 patients, 84 (31%) patients developed at least one postoperative complication. Major complications occurred in 32 (12%) patients. Most common complication was wound infection and it was significantly more common in stented patients (p = 0.017). Pancreatic fistula and post pancreatectomy hemorrhage (PPH) developed in 7.4% of patients. Thirteen patients (4.8%) required early re-operation and the most common cause of re-exploration was PPH. 90-day mortality was 1% (n = 3) and all 3 patients required re-exploration for PPH. Median postoperative hospital stay was 9 (5-51) days. Perioperative blood transfusions was the only independent predictor of postoperative complications after FP. CONCLUSIONS: Frey procedure is an acceptable treatment modality with low rates of mortality and reasonable perioperative morbidities. Minimizing blood transfusions may further improve 90-day outcomes.

RESUMO

Background: Diabetes is one of the most common chronic disease in the world and its prevalence in India is rising day by day. Diabetic patients often suffer from depression and anxiety which has a negative impact on patients resulting in non-adherence to medication, rapid disease progression and overall poor prognosis. India is the land of diversity and so are the causes of depression and anxiety in the people from different parts of the country. The study done in the current population has revealed certain indicators of both depression and anxiety that were not significant in previous studies. These new findings point towards the changing scenario and the need for more precise steps for improving the quality of life of diabetics. Aims: The study aims to determine the prevalence of depressive symptoms and anxiety among diabetic patients and the factors associated with them. Methods: A prospective cohort study was conducted with 305 participants among which 152 were diabetic while 153 were non diabetic patients. Depression and anxiety of the patients was measured through PHQ-9 scale and GAD-7 scale respectively. Factors associated with prevalence of depression and anxiety in the diabetic population was analysed. Results: The prevalence of depressive symptoms (39.5% versus 12.4%) and anxiety (36.2% versus 14.4%) were significantly higher in diabetic patients as compared to non-diabetic participants. Low-income, urban residence, unmarried status, insulin therapy, presence of retinopathy, and ischemic heart disease were significantly associated with depression among diabetic group of patients. Similarly the major predictors of anxiety were marital status, literacy and diabetic complications like neuropathy, retinopathy and ischemic heart disease. Conclusion: Our study shows depression and anxiety are highly prevalent among diabetic patients. All diabetic patients while seeking clinical contact should be screened for depression and anxiety especially those patients with predisposing risk factors.

RESUMO

Background: This systematic review and meta-analysis aims to determine the prevalence of the retrorenal colon (RRC) and its implications in percutaneous nephrolithotomy with the overall objective of promoting the prevention of associated iatrogenic complications. Methods: A systematic search of literature was conducted on the electronic databases PubMed, ScienceDirect, and Hinari to identify studies eligible for inclusion. Search results were screened by title and abstract, and those potentially relevant were evaluated by full text. Studies were deemed eligible for inclusion if they reported clear extractable data regarding the prevalence of the retro-renal colon. A meta-analysis was completed using MetaX1 to calculate the pooled prevalence of the retro-renal colon. Sub-group analysis was performed based on geographical regions from which the studies originated, imaging modality, and patient position. Results: 174 records were screened and a total of 10 records included in the analysis with retrospective cohort studies being the most common study design. A male predominance was seen in most sample sizes that had reported data on gender demographics ranging from 41.5-62%. The most common imaging modality utilized was computerized tomography (CT) scan followed by ultrasound. The range of the unweighted prevalence of retro-renal colon across all studies that had absolute numbers reported was from 3.5-25%. One of the studies reported a colonic perforation rate of 0.3% in patients without CT images. Conclusion: The retro-renal colon is a relatively common finding with observed preponderance to females and left lateralization. The presence of RRC increases the likelihood of colon perforations while gaining percutaneous access to the kidney. Pre-procedural imaging can help detect its presence and choose an appropriate route of entry. USG and CT have both been found useful as a modality to pick up RRC.

RESUMO

Chronic pancreatitis is (CP) is a progressive inflammatory disease of the pancreas associated with disabling abdominal pain and gradual deterioration of exocrine and endocrine function. Up to 50% of patients with CP may require surgery during the course of the disease. The main indication for surgery is intractable abdominal pain not amenable to medical and endoscopic therapy. The type of surgery depends on pancreatic ductal diameter and associated parenchymal pathology like inflammatory head mass. Frey procedure (FP) is an effective method for control of pain in patients with enlarged pancreatic head. FP can be performed with a very low mortality and an acceptable morbidity. Compared with pancreaticoduodenectomy (PD), FP has favourable outcomes in terms of operation time, blood loss, morbidity, post-operative hospital stay, intensive care unit stay, and quality of life. FP has shorter operation time and lower morbidity in comparison to Beger procedure. But, long-term pain control and exocrine and endocrine dysfunctions are comparable between PD, Beger and FP. FP is technically easier than PD and Beger procedure. FP is thus a widely acceptable procedure for CP with enlarged pancreatic head in absence of a neoplasia.

RESUMO

Background Most of the government-sponsored medical teaching institutions in India do not provide safety lancets, and hence, the students are compelled to use hypodermic needles. These needles are widely unpopular among students due to the potential hazards (pain, fear, anxiety) associated with them. This study aims to compare any difference in fear and anxiety associated with finger pricking with a hypodermic needle and a safety lancet. Methods This is a prospective cohort study. The current study included data from first-year undergraduate medical students for academic sessions 2021-22. Results A total of 121 students participated in the study. Eighty-two (67.8%) participants were male. 41/82 male participants and 20/39 female participants were allocated to the intervention cohort. 111 (91.7%) pricked their fingers by themselves. The sight of others pricking during the experiment (17 versus 5, p=0.004) and the thought of pain while pricking (36 versus 16, p<0.001) was significantly associated more with the use of a hypodermic needle compared to a safety lancet. There was no significant difference in students perceiving the smell of the hematology laboratory (4 versus 1, p=0.165) and the sight of blood (9 versus 3, p=0.064) as a factor influencing their fear and anxiety in both cohorts. There was no gender difference in the perception of these factors. Symptoms were significantly lower in the intervention cohort compared to the control cohort (8 versus 20, odds ratio 0.302, p=0.008). The most common symptom experienced was excessive sweating (n=22, 18.18%), followed by drying of the mouth (n=12, 9.91%). There was a significant difference in pain scores between the intervention and the control cohorts. There was no significant difference in pain scores among male and female subjects. Conclusion A considerable difference between the two cohorts was found. The use of lancets can be proposed to medical teaching institutions for psychological advantage, pain reduction, and overall better quality of the process.

RESUMO

Background and Aims: The cellular mechanism of liver injury related to arsenic toxicity is ill defined. It is thought that oxidative stress and mitochondrial dysfunction may play some role in arsenic-induced liver damage. In this study, we evaluated subcellular events within the primary cultured mouse hepatocytes when exposed to inorganic arsenic. Methods: Primary cultured mouse hepatocytes were treated with 10 µM arsenic for different time periods. Reactive oxygen species (ROS) formation, functional changes of the lysosome and mitochondria, and mode of hepatocytes death were studied by laser confocal microscopy, fluorescence spectroscopy, and flow cytometry. Expression of proapoptotic member of the BCL-2 family of genes BAX and antiapoptotic BCL-2 mRNA expression were studied by real-time PCR. Cytochrome c expression was studied by Western blotting. Results: Fluorescence spectroscopy as well as flow cytometric analysis revealed that arsenic-induced formation of ROS was time dependent. Confocal microscopy showed initiation of ROS formation from periphery of the hepatocytes at 30 min of arsenic exposure that progressed to central part of the hepatocytes at 3 h of arsenic exposure. The ROS formation was found to be NADPH oxidase (NOX) dependent. This low level of intracellular ROS induced lysosomal membrane permeabilization (LMP) and subsequently released cathepsin B to the cytosol. The LMP further increased intracellular ROS which in turn triggered induction of mitochondrial permeability transition (MPT). Pretreatment of hepatocytes with LMP inhibitor bafilomycin A (BafA) significantly decreased, and LMP inducer chloroquine (ChQ) significantly increased the production of ROS suggesting that LMP preceded enhanced ROS generation in response to arsenic. MPT was accompanied with increase in BAX : BCL2 mRNA ratio resulting in upregulation of caspase 3 and increased hepatocyte apoptosis. Conclusion: Although arsenic-related oxidative liver injury is well established, neither the site of origin of ROS nor the early sequence of events in arsenic toxicity due to ROS is known. We believe that our study provides evidences elucidating the early sequence of events that culminates in the death of the mouse hepatocytes during arsenic exposure.

RESUMO

The need for promoting diversity and equitable authorship representation in academics faces increasing recognition, with some articles pointing out the lack of diversity in specific fields. Currently, there are no such articles scrutinizing the author diversity in the field of Gastroenterology. Cochrane systematic reviews are perceived worldwide to be amongst the highest quality of evidence available, thereby its conclusions often impact policy and practice globally. However, little is known about the current state of authorship diversity in Gastroenterology-related Cochrane reviews.

RESUMO

Background Hepatoblastoma (HB) is a rare neoplasm of the liver, accounting for about 1% of all pediatric cancers. The aim of the present study is to report our experience with HBs over a period of five years from a tertiary center in Eastern India. Methodology This is a retrospective observational study. The data of all patients who were diagnosed with HB between August 2015 and December 2020 was reviewed. Results Twenty-three patients who were diagnosed and treated for HB at our center were included in the study. Sixteen (69.5%) of them were male. The median age of presentation was 14 (range, 3-58) months. An abdominal lump (n=23, 100%) and abdominal pain (n=11, 47.8%) were the most common presenting symptoms. The median level of serum alpha-fetoprotein at the time of initial evaluation was 8000 (878-1,280,000) ng/dL. The mean size of the largest focus in its largest dimension was 12.03±3.77 cm. The epithelial variant (n=22, 95.7%) was the most common histological subtype. One (4.3%), 10 (43.4%), 11 (47.8%), and one (4.3%) patient were found to have pre-treatment extent of tumor (PRETEXT) stages 1, 2, 3, and 4, respectively. Fifteen (65.2%) children were classified as standard risk and seven (34.7%) children as high risk. All the patients received neoadjuvant chemotherapy (NACT). The most commonly performed surgery was right hepatectomy (n=12, 52.1%). There were three (13%) cases of perioperative mortality. Four postoperative complications developed in three (13%) patients. Four (17.3%) patients developed chemotherapy-related complications. The median duration of follow-up was 31 (range, 0-58) months. Three (13%) patients developed relapses of the disease. Overall, five-year survival in our series was 73.9%. Conclusion This study shows that the overall outcomes of HB in a resource-limited setting such as ours are good with the adoption of multi-modality treatment. Managing chemotherapy-induced complications and making liver transplantation more feasible will improve the results further.

RESUMO

Background: Groove pancreatitis (GP) is a rare form of chronic pancreatitis primarily affecting the pancreatoduodenal groove. Very few studies have been published from India. The aim of the present study is to report our experience with Whipple's procedure for GP. Methodology: In this cross-sectional study, data of all patients who underwent Whipple's procedure for GP between August 2007 and July 2021 were retrospectively reviewed. Results: Of the total 504 Whipple's procedures, histopathologically proven GP was identified in 9 patients. All of them were male. Mean age at presentation was 42.66 ± 4.35 years. All of them had history of alcohol abuse. Eight (88.8%) of them had history of smoking. Postprandial abdominal discomfort and pain (n = 9, 100%) was the most common presenting symptom. Three (33.3%) patients had solid variety and six (66.6%) patients had cystic dystrophy of the duodenal wall. Two (22.2%) patients had mass in the head of the pancreas which was thought to be malignant. None of the patients underwent prior endoscopic management (stenting). Duration of surgery and blood loss was 330 (range, 300-379) minutes, and 250 (range, 200-750) ml respectively. There was no postoperative mortality. Postoperative complications developed in 5 (55.5%) patients. All the complications were managed conservatively. Median postoperative hospital stay was 10 (range, 9-16) days. Over a median follow-up of 41 (range, 12-120) months, complete remission of symptoms was achieved in 7 (78%) patients. Conclusion: Whipple's procedure is safe with acceptable perioperative outcomes and good long-term symptom control.
