RESUMEN
BACKGROUND: Although rectal administration of nonsteroidal anti-inflammatory drugs is recommended as the standard pharmacologic modality to prevent postendoscopic retrograde cholangiopancreatography (ERCP) post-ERCP pancreatitis (PEP), vigorous periprocedural hydration (vHR) with lactated Ringer's solution (LR) is emerging as an effective prophylaxis modality for PEP. There has been no head-to-head comparison between these 2. STUDY: This was a single-center, randomized, open-label, noninferiority, parallel-assigned, equal allocation, controlled clinical trial in a tertiary care hospital. Consecutive adults referred for ERCP, satisfying predefined inclusion criteria, underwent simple randomization and blinded allocation into 2 groups. Those allocated to vHR received intravenous LR at 3 mL/kg/h during procedure, 20 ml/kg bolus immediately afterward, and then at 3 mL/kg/h for another 8 hours. Those randomized to rectal Indomethacin received only per-rectal 100 mg suppository immediately post-ERCP. Assuming PEP of 9% in Indomethacin arm and noninferiority margin of 4%, we calculated sample size of 171 patients in each arm for 80% power and α-error 5%. Primary outcome was incidence of PEP, within 1 week, as defined by Cotton's criteria. All analysis were done by intention-to-treat. RESULTS: Between October, 2017 to February, 2018, 521 patients were assessed. In all, 352 were enrolled, 178 randomized to vHR, and 174 to per-rectal Indomethacin. Baseline details and ERCP outcomes were not different between 2 groups. PEP occurred in 6 (1.7%) overall, with 1 (0.6%) in hydration arm, and 5 (2.9%) in indomethacin arm; an absolute risk reduction of 2.3% (95% confidence interval: 0.9%-3.5%) and odds ratio of 0.19 (95% confidence interval: 0.02-1.65). Three patients developed severe PEP, all receiving indomethacin. CONCLUSIONS: vHR with LR is noninferior to postprocedure per-rectal Indomethacin for PEP prevention (ClinicalTrials.govID:NCT03629600).

INTRODUCTION: There is paucity of data regarding economic burden, employment affection, psychological and nutritional status of CP patients, of non-alcoholic etiology, especially during their periods of stable disease, i.e., without any complications and/or recent endoscopic/surgical interventions. METHODS: In a prospective cohort study, conducted in outpatient clinic of a tertiary-care hospital, 66 consecutive adults with Idiopathic CP (± diabetes) and 152 matched (by age, socioeconomic status and monthly income) healthy controls were assessed for: (1) healthcare expenses in previous month by recall (catastrophic if > 40% of income); (2) nutritional status by anthropometry and food frequency questionnaire; (3) psychological status by Hospital Anxiety and Depression Scale (HADS); and (4) work-impairment by work productivity and activity impairment questionnaire: general health (WPAI-GH). CP patients were again reassessed for the above parameters after 6 and 12 month, respectively. RESULTS: Seventy-six percent CP patients (vis-à-vis 0% controls) had catastrophic healthcare expenditure. Forty-nine percent of CP patients(vis-à-vis 0% controls) met their healthcare expenses by either selling assets or obtaining loans at high-interest or from charitable donations. CP patients had lower BMI, were more likely to be malnourished and had a lower calorie intake vis-à-vis controls (median (IQR) recommended daily allowance (RDA): 71(19)% vs 97(23)%; [p < 0.0001]). Their median HADS Anxiety and depression scores were significantly higher than controls. Thirty-one (47%) CP patients were employed vis-a-vis 102 (67%) controls (p = 0.006); they had significantly higher work impairment. After one year, there was improvement in some of these above parameters in CP patients. CONCLUSION: Idiopathic CP outpatients had catastrophic healthcare expenditure, malnutrition, abnormal psychological scores and work-impairment vis-à-vis healthy controls. Some of these parameters improved on follow-up.

Diagnosis of hepatocellular carcinoma (HCC) remains challenging to clinicians, particularly in a patient with low alpha-fetoprotein. Here, in silico, ex vivo and in vitro data were combined to identify liver-specific exosomal miRNAs as an early diagnostic marker for HCC. Transcriptome profiling for mRNA and small RNA in same HCV-HCC and normal liver tissues followed by cross-validation of 41 deregulated miRNAs (log2 FoldChange > 1.5, Padj < .1) with GEO/TCGA datasets of HCV/HBV related HCC vs normal/adjacent tissue revealed three miRNAs were commonly deregulated (miR-10b/miR-21/miR-182) among all HCC irrespective of viral etiology. Targets of top deregulated miRNAs were identified by TargetScan/miRwalk and validated in mRNA transcriptome data followed by Panther/Gene Ontology enrichment/Cytoscape analysis suggested that targets were mostly from carcinogenesis pathways. Hence, those miRNAs were validated in normal and HCV-HCC tissues by qRT-PCR and subsequently in plasma-derived-exosomes of both HBV/HCV infected non-HCC (chronic hepatitis [CH]/liver cirrhosis [LC]) and HCC samples, and in liver-specific Anti-Asgr2 immuno-enriched exosomes. Exosomes were verified using Nanosight/TEM/immune-blotting with anti-Alix/anti-GRP78/anti-Asgr2. Along with miR-21-5p, miR-10b-5p/miR-221-3p/miR-223-3p was found significantly upregulated in the exosome of HCC patients than CH/non-HCC. The comparable expression pattern was seen in anti-Asgr2 immuno-precipitated exosomes. Interestingly, the AFP level was found below 250 ng/mL in about 94% of HCV-HCC and 62% of HBV-HCC patients. ROC analysis showed that miR-10b-5p + miR-221-3p + miR-223-3p + miR-21-5p could differentiate CH/non-HCC(CH + LC) from HCC with AUROC: 0.86 (97.5% CI: 0.77-0.94)/0.80 (97.5% CI: 0.70-0.89), sensitivity: 74%/58% and specificity: 86%/95% while miR-10b-5p + miR-221-3p + miR-223-3p showed AUROC: 0.84 (97.5% CI: 0.74-0.94)/0.74 (97.5% CI: 0.63-0.84), sensitivity: 86%/86% and specificity:66%/53% for low AFP-HCC vs CH/non-HCC, respectively, having better sensitivity than the combination of four miRNAs. Multivariate analysis further revealed low Albumin and high miR-21-5p as probable independent risk factor for HCC.

BACKGROUND: Most often, the patients with pancreatic diseases are presented with a mass in pancreatic head region and existing methods of diagnosis fail to confirm whether the head mass is malignant or benign. As subsequent management of the disease hugely depends on the correct diagnosis, we wanted to explore possible biomarkers which could distinguish benign and malignant pancreatic head masses. METHODS: In order to address that gap, we performed a case-control study to identify genome-wide differentially expressed coding and noncoding genes between pancreatic tissues collected from benign and malignant head masses. These genes were next shortlisted using stringent criteria followed by selection of top malignancy specific genes. They subsequently got validated by quantitative RT-PCR and also in other patient cohorts. Survival analysis and ROC analysis were also performed. RESULTS: We identified 55 coding and 13 noncoding genes specific for malignant pancreatic head masses. Further shortlisting and validation, however, resulted in 5 coding genes as part of malignancy specific multi-gene signature, which was validated in three independent patient cohorts of 145 normal and 153 PDAC patients. We also found that overexpression of these genes resulted in survival disadvantage in the patients and ROC analysis identified that combination of 5 coding genes had the AUROC of 0.94, making them potential biomarker. CONCLUSIONS: Our study identified a multi-gene signature comprising of 5 coding genes (CDCA7, DLGAP5, FOXM1, TPX2 and OSBPL3) to distinguish malignant head masses from benign ones.

BACKGROUND: Frey procedure (FP) has become the standard of treatment for patients with painful chronic pancreatitis and inflammatory head mass. Biliary diversion (BD) is necessary when there is persistent biliary obstruction after adequate head coring. The aim of the present study was to assess the impact of types of biliary diversion on short-term outcome and rates of stricture recurrence. METHODS: All the patients, who underwent FP combined with BD between August 2007 and July 2017 in the Department of Surgical gastroenterology, Institute of Postgraduate Medical Education and Research, Kolkata, India, were retrospectively reviewed. The types of BD performed were choledochojejunostomy (Group A) or opening of the CBD in the resection cavity (Group B). RESULTS: During the study period, 36 patients underwent FP with BD. Choledochojejunostomy was performed in 21 patients and opening of the CBD in the resection cavity in 15 patients. Preoperative characteristics and early surgical outcomes were comparable except the postoperative stay which was longer in those who underwent choledochojejunostomy (p = 0.044). Pain control was similar. Over a median follow-up of 72 months, five patients in the Group B developed stricture recurrence which was significantly higher than those of Group A (p = 0.008). CONCLUSION: Choledochojejunostomy combined with FP achieves efficient BD with a lower rate of restricture compared with opening of the CBD in the resection cavity.

OBJECTIVE: The aim of this study was to report on the short-and long-term outcomes of surgery for chronic pancreatitis (CP) in children. METHODS: All the children, who underwent surgery for CP between August 2007 and July 2019 in the Department of Surgical gastroenterology, Institute of Postgraduate Medical Education and Research, Kolkata, India were retrospectively reviewed. RESULTS: Of the total 54 patients, 33 (61%) were girls. The median age at operation was 16.5 years. The median duration between onset of pain and surgery was 36 months. 26% of patients were referred after failure of endotherapy. The most common indication for surgery was pain (94%). Surgery performed included modified Puestow (n = 26), Frey (n = 25), and Izbicki procedures. Twelve postoperative complications developed in ten (18.5%) patients. Most common complication was wound infection. Pancreatic leak developed in four (7.4%) patients (type A = 3, type B = 1). Median postoperative hospital stay was 8 days. There was no in-hospital mortality. Over a median follow-up of 48 months, 83% of patients had complete pain control. Weight gain was achieved in 77% of patients. New-onset diabetes and exocrine insufficiency developed in 4 and 14% of patients, respectively. CONCLUSIONS: Surgery is safe with fairly acceptable perioperative complications and good long-term pain control.

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) is considered as one of the most aggressive cancers lacking efficient early detection biomarkers. Circulating miRNAs are now being considered to have potency to be used as diagnostic and prognostic biomarkers in different diseases as well as cancers. In case of cancer, a fraction of the circulating miRNAs is actually derived from the tumour tissue. This fraction would function as stable biomarker for the disease and also would contribute to the understanding of the disease development. There are not many studies exploring this aspect in pancreatic cancer and even there is not much overlap of results between existing studies. METHODS: In order to address that gap, we performed a miRNA microarray analysis to identify differentially expressed circulating miRNAs between PDAC patients and normal healthy individuals and also found two more similar datasets to perform a meta-analysis using a total of 182 PDAC patients and 170 normal, identifying a set of miRNAs significantly altered in patient serum. Next, we found five datasets studying miRNA expression profile in tumour tissues of PDAC patients as compared to normal pancreas and performed a second meta-analysis using data from a total of 183 pancreatic tumour and 47 normal pancreas to detect significantly deregulated miRNAs in pancreatic carcinoma. Comparison of these two lists and subsequent search for their target genes which were also deregulated in PDAC in inverse direction to miRNAs was done followed by investigation of their role in disease development. RESULTS: We identified 21 miRNAs altered in both pancreatic tumour tissue and serum. While deciphering the functions of their target genes, we characterized key miR-Gene interactions perturbing the biological pathways. We identified important cancer related pathways, pancreas specific pathways, AGE-RAGE signaling, prolactin signaling and insulin resistance signaling pathways among the most affected ones. We also reported the possible involvement of crucial transcription factors in the process. CONCLUSIONS: Our study identified a unique meta-signature of 21 miRNAs capable of explaining pancreatic carcinogenesis and possibly holding the potential to act as biomarker for the disease detection which could be explored further.

Controversies about the origin of circulating miRNAs have encouraged us to identify organ specific circulating miRNAs as disease biomarkers. To identify liver-specific miRNAs for hepatocellular carcinoma (HCC), global expression profiling of miRNAs in liver tissue of HBV-HCC and HBV-control with no or mild fibrosis was evaluated. A total of 40 differentially expressed miRNAs were identified in HCC. Among ten highly altered miRNAs, six miRNAs were successfully validated in tissues, whereas only two miRNAs, miR-126 and miR-142-3p showed increased expression in plasma of HBV-HCC compared to HBV-non-HCC patients. Subsequently, ROC curve analysis revealed that neither miR-126 nor miR-142-3p performed better than AFP in discriminating HCC from non-HCC while combination of each with AFP showed significantly higher efficiency rather than AFP alone (AUC: 0.922, 0.908 vs. 0.88; sensitivity: 0.84, 0.86 vs. 0.82 and specificity: 0.92, 0.94 vs. 0.86 respectively). Interestingly, triple combination of markers (miR-126 + miR-142-3p + AFP) showed no additive effect on efficiency (AUC: 0.925) over the dual combination. Again, the expression of only miR-126 was noticed significantly higher in HBV-HCC patients with low-AFP [<250 ng/ml] compared to either non-HCC or liver cirrhosis (AUC: 0.77, 0.64, respectively). Furthermore, no alteration in expression of mir-126 in HCV-HCC or non-viral-HCC revealed that miR-126 + AFP might be specific to HBV-HCC. To understand the physiological role of these two miRNAs in hepato-carcinogenesis, target genes related to cancer pathways (APAF1, APC2, CDKN2A, IRS1, CRKL, LIFR, EGR2) were verified. Thus, combination of circulating miR-126 + AFP is a promising noninvasive diagnostic biomarker for HBV-HCC and may be useful in the management of HCC patients.

BACKGROUND: Although, recurrent pyogenic cholangitis (RPC) is prevalent in several parts of India, there is paucity of published literature from India. The aim of this study was to report on the short and long-term outcomes of surgery for RPC. METHODS: All the patients, who underwent surgery for RPC between August 2007 and February 2016 in the Department of Surgical gastroenterology, Institute of Postgraduate Medical Education and Research, Kolkata, India were retrospectively reviewed. RESULTS: Of the total 94 patients, 66 (70%) were women. The median age at presentation was 40 years. Left lobe was solely involved in 49% of patients. Left hepatectomy was performed in 23/44 (52%) patients who underwent liver resection. Thirty two postoperative complications developed in 27 patients (29%). Complete stone clearance was possible in 83% of patients after primary surgery. Over a median follow up of 36 months, seventy one of 87 patients (81%) remained free of stones. Recurrent cholangitis occurred 10 of 87 patients (11%). CONCLUSIONS: Surgery plays an important role in the management of RPC achieving excellent short and long-term outcomes.

Macrophage infiltration into adipose tissue during obesity and their phenotypic conversion from anti-inflammatory M2 to proinflammatory M1 subtype significantly contributes to develop a link between inflammation and insulin resistance; signaling molecule(s) for these events, however, remains poorly understood. We demonstrate here that excess lipid in the adipose tissue environment may trigger one such signal. Adipose tissue from obese diabetic db/db mice, high fat diet-fed mice, and obese diabetic patients showed significantly elevated fetuin-A (FetA) levels in respect to their controls; partially hepatectomized high fat diet mice did not show noticeable alteration, indicating adipose tissue to be the source of this alteration. In adipocytes, fatty acid induces FetA gene and protein expressions, resulting in its copious release. We found that FetA could act as a chemoattractant for macrophages. To simulate lipid-induced inflammatory conditions when proinflammatory adipose tissue and macrophages create a niche of an altered microenvironment, we set up a transculture system of macrophages and adipocytes; the addition of fatty acid to adipocytes released FetA into the medium, which polarized M2 macrophages to M1. This was further confirmed by direct FetA addition to macrophages. Taken together, lipid-induced FetA from adipocytes is an efficient chemokine for macrophage migration and polarization. These findings open a new dimension for understanding obesity-induced inflammation.

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.
RESUMEN
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.
RESUMEN
INTRODUCTION: Endoclip migration into the common bile duct after laparoscopic cholecystectomy is a rare complication. Very few cases have been reported in the literature, mostly in the form of case reports. CASE DESCRIPTION: We report a case of Endoclip migration into the bile duct with stone formation 6 y after laparoscopic cholecystectomy. The patient presented with recurrent abdominal pain and intermittent jaundice for 6 mo. Diagnosis was suspected when a computed tomography scan of the abdomen showed a metallic density artifact in the lower end of the bile duct. The diagnosis was confirmed by endoscopic retrograde cholangiopancreatography. The patient was successfully managed by endoscopic stone and clip removal. DISCUSSION: Endoclip migration with biliary complications should be considered in the differential diagnosis of postcholecystectomy problems. The clinical manifestations and management are similar to that of noniatrogenic choledocholithiasis.

ABSTRACT: Primary hepatic leiomyosarcoma is a rare hepatic malignancy which requires exclusion of other primary site of origin. Clinical presentation and imaging of this tumor is nonspecific and mimics many other hepatic neoplasms. A 62-year-old female patient presents here with right hepatic mass with insidious onset and radiological features favoring a benign solid lesion suggestive of focal nodular hyperplasia. On right hepatectomy, an encapsulated mass identified about 11 cm in maximum dimension with pushing margin and central scar-like area. Histopathological examination reveals a spindle cell tumor and panel of immunohistochemical markers is required to distinguish it from other morphological mimickers. Diagnosis of primary hepatic leiomyosarcoma requires histopathology along with immunohistochemical examination. It is thus advisable to do preoperative biopsy with immunohistochemistry in all patients having atypical imaging and clinical features.
RESUMEN
Backgrounds/Aims: Extra hepatic portal venous obstruction (EHPVO) is the most common cause of portal hypertension in Indian children. While endoscopy is the primary modality of management, a subset of patients require surgery. This study aims to report the short- and long-term outcomes of EHPVO patients managed surgically. Methods: All the patients with EHPVO who underwent surgery between August 2007 and December 2021 were retrospectively reviewed. Postoperative complications were classified after Clavien-Dindo. Binary logistic regression in Wald methodology was used to determine the predictive factors responsible for unfavourable outcome. Results: Total of 202 patients with EHPVO were operated. Mean age of patients was 20.30 ± 9.96 years, and duration of illness, 90.05 ± 75.13 months. Most common indication for surgery was portal biliopathy (n = 59, 29.2%), followed by bleeding (n = 50, 24.8%). Total of 166 patients (82.2%) had shunt procedure. Splenectomy with esophagogastric devascularization was the second most common surgery (n = 20, 9.9%). Nine major postoperative complications (Clavien-Dindo > 3) were observed in 8 patients (4.0%), including 1 (0.5%) operative death. After a median follow-up of 56 months (15-156 months), 166 patients (82.2%) had favourable outcome. In multivariate analysis, associated splenic artery aneurysm (p = 0.007), isolated gastric varices (p = 0.004), preoperative endoscopic retrograde cholangiography and stenting (p = 0.015), and shunt occlusion (p < 0.001) were independent predictors of unfavourable long-term outcome. Conclusions: Surgery in EHPVO is safe, affords excellent short- and long-term outcome in patients with symptomatic EHPVO, and may be considered for secondary prophylaxis.
RESUMEN
Choledochal cyst (CC) is an atypical congenital abnormality of the biliary system. CC more than 10 cm is rare and only a few cases are reported. Herein, we reported a 25 × 18 cm CC and highlighted how definitive treatment after a timely diagnosis provides good prognosis irrespective of the size.
RESUMEN
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.

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 (â¼90 %) 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.
RESUMEN
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.
RESUMEN
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.
