RESUMEN

Objectives: Pancreatic resection may be required in the treatment of patients with pathologies of the pancreas. Total pancreatectomy is a major surgical procedure with serious risk of mortality and morbidity, and patient selection is important for prognosis. The endocrine and exocrine pancreatic insufficiency that develops in patients after total pancreatectomy can lead to a serious decrease in the quality of life of the patients due to pain, diarrhea, vomiting etc. Our aim was to evaluate the effect of total pancreatectomy with spleen preservation as well as splenectomy on the quality of life of the patients. Material and Methods: In our study, we retrospectively analyzed the data of patients diagnosed with pancreatic cancer, intrapapillary mucinous neoplasia, pancreatic neuroendocrine tumors, and chronic pancreatitis undergoing from partial to total pancreatic resections in our clinic between 12/2017 and 12/2022. Quality of life was compared using the EORTC QLQ-C30 scale. Results: A total of 47 total pancreatectomy patients, 30 (63.8%) males and 17 (36.2%) females, were included in the study. Mean age of the patients was 61.38 (39-83) years. Five (35.7%) patients underwent perioperative total pancreatectomy because of high risk of pancreatic fistula development due to hard parenchyma and narrow pancreatic duct. Patients had a perioperative blood loss of 500 mL or more, and there was a statistically significant increase in perioperative blood loss compared to patients without vascular resection (p <0.001). Forty (85.1%) patients used enzyme preparations to replace pancreatic enzymes. Conclusion: After total pancreatectomy, quality of life of the patients is reduced both by surgical factors and by metabolic factors due to endocrine and exocrine insufficiency in the postoperative period.

RESUMEN

Hepatocellular carcinomas (HCCs) with steatohepatitis and steatosis are reported with varying definitions and clinicopathologic features. We aimed to search the attributes of steatohepatitic hepatocellular carcinoma (SH-HCC) and steatotic-HCC in our series. A retrospective clinicopathologic analyses of 150 HCCs and immunostaining for C-reactive protein (CRP) and serum amyloid A (SAA) were performed. Tumors were reclassified as all SH-HCC, limited SH-HCC, typical SH-HCC (steatohepatitic features in >5%, 5% to 50%, and ≥50% of the tumor, respectively), steatotic-HCC, and classic HCC (C-HCC). Group comparisons were made using Kruskal-Wallis and Kaplan-Meier tests. The background etiology in all SH-HCCs was pure viral in 51.4%, nonalcoholic steatohepatitis (NASH)/alcoholic liver disease (ALD) alone/mixed in 34.3%, and unidentified in normal liver in 14.3%. All SH-HCCS (n=35, 23.3%) and typical SH-HCCs (n=13, 8.6%) had higher NASH/ALD. Limited SH-HCCs (n=22, 14.6%) had higher ALD (all P<0.05). Typical SH-HCCs tended to have more NASH (P=0.054). Steatotic-HCCs (n=13, 9%) and C-HCCs (n=102, 68%) had higher pure viral etiology and serum CRP (all P<0.05). CRP and SAA were positive in 69% and 27% of the tumors, respectively. SAA positivity correlated with ALD (P=0.026). In the overall group disease-free survival rates at 1, 5, 10, and 20 years were 97.0%, 82.3%, 79.6%, and 77.2%, respectively. Demographics, tumor characteristics, CRP and SAA positivity, and survival were similar between the groups (P>0.05). SH-HCC is heterogenous in terms of underlying etiologies, and can be seen in NASH/ALD, pure viral and noncirrhotic/normal background. The ≥50% cutoff for the definition of SH-HCC can lead to overlook ALD-related SH-HCC. Steatotic-HCC seems more similar to C-HCC rather than SH-HCC, but none of them feature as a different prognostic group.

RESUMEN

Background/aim: In this study, the efficiency of using low-dose hepatitis B immunoglobulin (HBIG) plus antiviral treatment according to individual needs has been evaluated in posttransplant hepatitis B virus (HBV) patients. Materials and methods: We retrospectively evaluated 179 patients who were admitted between 2009 and 2014. Five thousand IU intravenous HBIG was given in the anhepatic phase, and 400 IU/day intramuscular (IM) HBIG was given in the posttransplant period. After HBsAg seroconversion, 400 IU IM HBIG was continued as prophylaxis every two weeks. Results: The average follow-up period was 26 (2­65) months. Seventy patients had hepatocellular carcinoma (HCC). The HBV recurrence was 4.5% in the first year, and 5.8% in the third year. The HBsAg became negative in 11 (2­63) days, and anti-HBs became positive in 9 (1­31) days. HBsAg positivity occurred in 6 patients during the follow-up period. Five of these patients were those who underwent transplantation due to HCC. In 5 of the HCC patients, in whom HBsAg became positive, tumor recurrence was observed after 0.3­9.9 months. HBsAg positivity was more frequently detected in patients with HCC (P = 0.009). Conclusion: The HBV recurrence should be evaluated as a predictor of the HCC recurrence in patients who were transplanted due to HCC.

RESUMEN

BACKGROUND/AIMS: The aim of this study was to evaluate the effect of the Milan criteria on the hepatitis B virus (HBV) and hepatocellular carcinoma (HCC) recurrence in patients who underwent living donor liver transplantation due to HBV-induced cirrhosis and HCC. MATERIALS AND METHODS: We evaluated a total of 142 patients, 88 who underwent transplantation due to HBV-induced cirrhosis and 54 due to HCC, between 2009 and 2014. In the posttranplant period, after the HBsAg seroconversion, 400 IU of hepatitis B immunoglobulin were applied intramuscularly every 2 weeks, and daily nucleos(t)ide analogs were continued as prophylaxis. The HBV recurrence was defined as the presence of HBsAg in serum. Patients were screened for alpha-fetoprotein levels and imaging for evaluation of HCC recurrence. RESULTS: The average follow-up period was 26 (2-65) months. Fifty-four patients had HCC. The HCC recurrence was observed in 12 patients during the follow-up period. The HBV recurrence was observed in four patients. Three of the patients who developed HBV recurrence had liver transplantation due to HCC. Tumor recurrence was observed 1.4-12 months following the HBV recurrence. The HCC recurrence within the Milan criteria and beyond the Milan criteria was 0% vs. 28.4 % in the first year and 3.4% vs. 47.5% in the third year. The cumulative incidence of the HBV recurrence was 2.8% and 3.7% for the first year and 3.7% for the third year. The HBV recurrence was more frequently detected in patients with HCC (p=0.048), especially with HCC beyond the Milan criteria (p=0.044). CONCLUSION: The HBV recurrence should be evaluated as a predictor of the HCC recurrence in patients who underwent liver transplantation due to HCC with exceeding Milan criteria.

RESUMEN

Objective. To evaluate liver anatomy with a view to access unerring surgery in liver donors. Summary Background Data. Liver transplantation, the unique curative treatment option for end-stage hepatic failure, has become routinely practicable, which was inconceivable in the past. But, the vascular and biliary anatomy of the liver has not been completely disclosed yet. Methods. From 1994 to 2009, we have done a research on 496 liver donors. The data were accumulated and categorized according to the most widely used classification systems. Results. Of 496 liver donors, 393 (79.1%) underwent the right donor hepatectomy, 98 (19.9%) were performed the left lateral segmentectomy, and 5 donors (1%) underwent the left donor hepatectomy surgery. Given the data regarding to 398 liver donors undergone right and left donor hepatectomy, arteries, bile ducts, and portal vein showed classical anatomy in 107 (21.6%) donors. Variations in all three systems were found in 16 donors (3.2%). In the remaining 275 donors (75.2%), anatomical variations were found at either of arterial, biliary, or portal system. Conclusions. Our study could come up to actual estimate in liver anatomy as any of donors have not been removed in our institute due to high hilar dissection technique.

RESUMEN

AIMS AND BACKGROUND: To evaluate the treatment results of gemcitabine alone and concurrent with radiotherapy after R0/R1 resection of locally advanced pancreatic cancer. METHODS AND STUDY DESIGN: From 1999 to 2005, 55 patients with stage II resected pancreatic cancer treated with gemcitabine-based radiochemotherapy were retrospectively evaluated. Initially, one cycle of induction gemcitabine was administered and followed by weekly gemcitabine concurrent with radiotherapy. After the completion of radiochemotherapy, patients received 3 additional courses of gemcitabine. RESULTS: Thirteen patients were stage IIA and 42 were stage IIB. Forty-six patients (83.6%) had R0 and 9 patients (16.4%) had R1 resection. All of the patients received induction chemotherapy and radiotherapy, all but 3 received concurrent radiochemotherapy, and 46 (84%) patients received maintenance chemotherapy. During induction, concurrent and maintenance phases of the protocol, 11%, 13.5% and 19.5% of the patients had at least one > or = grade 3 toxicity, respectively. Within a median 47 months (range, 34-105) of follow-up, 4 (7.3%) patients had isolated local recurrence, 5 (9%) patients had local recurrence and distant metastases, and 27 (49%) had only distant metastases. Median disease-free survival and overall survival were 13 (range, 4-105) and 19 months (range, 6-105), respectively. In multivariate analysis, nodal stage, AJCC stage and number of lymph nodes dissected were the significant factors affecting disease-free survival whereas Karnofsky performance status was the only significant factor for overall survival. CONCLUSIONS: The prognosis for pancreatic cancer remains poor despite adjuvant radiochemotherapy. More aggressive treatments should be considered in patients with unfavorable prognostic factors.

RESUMEN

Matrix metalloproteinases (MMPs) are known to play an important role in cell migration during cancer invasion by degrading extracellular matrix proteins. This study aimed to determine the role of MMP-9 in hepatocellular carcinoma (HCC) carcinogenesis. Eighty-nine cases who underwent liver transplantation for HCC in cirrhotic liver were selected for this study. The tumor characteristics such as nodule number, maximal diameter, portal vein invasion, and the preoperative alpha-fetoprotein levels were reviewed. The intensity of immunostaining and the percentage of immunoreactive cells with MMP-9 were evaluated. All patients were evaluated for HCC recurrence and/or death, and cause of death was noted. There was a lower survival and more recurrence risk among participants with 4 or more nodules exceeding 3 cm in diameter, with poorly differentiated tumor, and with large-vessel involvement. Eleven patients developed recurrent HCC (12.4%). Twelve patients died as a result of HCC (13.5%). Among 89 HCCs, the incidences of a weak (+) and moderate (++) expression of MMP-9 in carcinoma cells were 30.3% (23/89) and 43.8% (39/89), respectively. Increased expression and intensity of MMP-9 were found to be inversely associated with poor tumor differentiation (P = 0.016, P = 0.009, respectively). A significant correlation between expression and intensity of MMP-9 and large vascular invasion (P = 0.01, and P = 0.03) was also observed. As far as prognosis is concerned, increased immunoreactivity and intensity of MMP-9 were found to exert an unfavorable impact on overall survival rates (P < 0.01, P = 0.01, respectively) and recurrences (P = 0.001, P = 0.02). Multivariate analyses revealed that MMP-9 staining percentage (P = 0.007) and portal vein invasion (P = 0.002) were independent predictors of survival, whereas the only independent predictor of recurrences was portal vein invasion (P = 0.007). In this study, our results indicate a positive association between MMP-9 expression and histopathologic parameters that indicate poor prognosis. We conclude that together, MMP-9 staining percentage and portal vein invasion in HCC may aid to predict poor outcome. Nevertheless MMP-9 staining percentage is expected to be a potential predictive marker on survival and needs to be studied more in detail.

RESUMEN

Pancreatic lipomatosis is characterized as massive lipid infiltration of the pancreatic tissue. Although its etiology is ill defined; obesity, diabetes mellitus, chronic pancreatitis, hereditary pancreatitis, and conditions that cause pancreatic ductal obstruction, for example tumors and stones, are related to its pathogenesis. Recently, with the increased use of computerized tomography and magnetic resonance imaging, it has become possible to observe the fat replacement of the pancreas. Herein, we report a 60-year-old man complaining of abdominal pain and weight loss. Preoperative work-up revealed a locally advanced (Stage III) pancreatic adenocarcinoma. Multimodal treatment was carried out and a 100% complete response was detected after neoadjuvant therapy. The patient underwent a standard pancreaticoduodenectomy, without complications. The tissue pathology revealed lipomatosis of the pancreas. He was disease-free and symptom-free at 1 year follow-up. To our knowledge, this is the first report in the literature of pancreatic head carcinoma with total fat replacement of the pancreas after neoadjuvant chemoradiotherapy.

RESUMEN

We analyzed infections that occurred within one month prior to LT, identified factors associated with their occurrence and effect of infections on post-transplant mortality. The study group included 40 consecutive children who underwent LT. Sites and types of infection and culture results were recorded prospectively. IID was assessed. Risk factors for the infectious events were analyzed. Forty infection episodes were found in 24 patients (60%); 90% were bacterial, 7.5% fungal, and 2.5% viral. Overall, IID was 38.2 per 1000 patient days. Sites of bacterial infection were urinary tract in 13 events (36.1%) and blood stream in 11 events (30.5%). Bacteremia (culture positive infection episodes) was identified in 19 events (52.7%). Gram-negative isolates were twice as frequent as Gram-positive infections (63.1% vs. 36.9%). Risk factors for the infectious complications were young age, low body weight, prior abdominal surgery, chronic liver disease related to biliary problems, presence of ascites, portal hypertension and cirrhosis, and high PELD score (p < 0.05 for all). Infectious complications in pediatric LT candidates are common. Preventive measures are important not only to reduce the infectious complications but also to prevent the post-operative mortality.

RESUMEN

OBJECTIVE: The aim of this study was to evaluate the negative effects of the Pringle maneuver on pancreatic tissue with respect to the time of performing the maneuver. Moreover, the efficacy of octreotide therapy on pancreatic changes at the time of the Pringle maneuver was assessed. ANIMALS: Fifty male Wistar Albino rats were randomized into 5 groups. DESIGN: The groups were formed as follows: Group A: sham operation, Group B: Pringle maneuver for 30 min plus octreotide (PM30-OCT), Group C: Pringle maneuver for 60 min plus octreotide (PM60-OCT) and Group D: Pringle maneuver for 30 min plus 0.9 % saline solution (PM30-SS), Pringle maneuver for 60 min plus 0.9 % saline solution (PM60-SS, Group E). MAIN OUTCOME MEASURES: Blood samples for the evaluation of both amylase and lipase levels were taken via the portal vein. Levels of glutathione, glutathione reductase, catalase, myeloperoxidase, nitric oxide, xanthine oxidase, malondialdehyde, tumour necrosis factor alpha (TNF-alpha), and interleukin-1 beta (IL-1 beta) were assessed in the excised pancreatic tissue. RESULTS: In the octreotide-treated groups, the catalase level was significantly higher in Group B (PM30-OCT) as compared to Group C (PM60-OCT). Amylase, lipase, NO and IL-1 beta levels were higher in Group C (PM60-OCT). In the saline solution-treated groups, the catalase level was significantly higher in Group E (PM60-SS) than in Group D (PM30-SS) while nitric oxide and glutathione levels were found to be significantly lower in Group E (PM60-SS) than in Group D (PM30-SS). Comparison of those groups using the Pringle maneuver for 30 minutes, the octreotide-treated group (Group B, PM30-OCT) was found to have a higher degree of edematous change than the saline-treated group (Group D, PM30-SS). Among the treatment groups, TNF-alpha expression decreased with increasing occlusion time. CONCLUSION: In this study, pancreatic damage and the duration of the Pringle maneuver are directly proportional to each other. Moreover, the administration of octreotide prior to the Pringle maneuver contributed to the pancreatic damage.

RESUMEN

Intrahepatic cholangiocarcinoma is subdivided as mass-forming, periductal-infiltrating, and intraductal-growing types. Intraductal-growing type is an entity described in recent years as mucin-producing intrahepatic cholangiocarcinoma or intrahepatic (biliary) intraductal papillary mucinous neoplasia (b-IPMN). b-IPMN is classified as adenoma, borderline tumor, carcinoma in situ, and carcinoma, from benign to malignant. Using a different classification, b-IPMNs are subdivided into intestinal, pancreatobiliary, gastric, or oncocytic based on morphology of the cells forming the lesion and expression of MUC1, MUC2, and MUC5 gene proteins in the mucin family. The clinical and histopathological features of b-IPMN diagnosed in three cases are presented herein. Case 1 was classified as borderline. Case 2 was diagnosed as carcinoma in situ. Case 3 had large invasive areas, and was diagnosed as carcinoma. In all three cases, immunohistochemical investigation revealed MUC1 and MUC5AC to be positive, and MUC2 to be negative. We present herein three cases diagnosed with the clinical and pathological findings of a new entity in the literature, b-IPMN, and we discuss the macroscopic, histological, and immunohistochemical features.

RESUMEN

BACKGROUND/PURPOSE: Portal vein embolization is used in the treatment of hepatocellular cancer, with the purpose of enhancing resectability. However, regeneration is restricted due to hepatocellular injury following chemotherapeutics (e.g. doxorubicin). The aim of this study was to investigate whether hyperbaric oxygenation (HBO) can alleviate the hepatotoxicity of chemotherapy and improve regeneration in the injured liver. METHODS: Rats were allocated to four experimental groups. Group I rats were subjected to right portal vein ligation (RPVL); rats in groups II and III were administered doxorubicin prior to RPVL, with group III rats being additionally exposed to HBO sessions postoperatively; group IV rats was sham-operated. All rats were sacrificed on postoperative day 7, and liver injury was assessed by measuring alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels. Protein synthetic ability was determined based albumin levels and liver regeneration by the mitotic index (MI). RESULTS: The AST and ALT values of group II rats were significantly higher than those of group I, but not those of group III. Rats treated with doxorubicin and HBO (groups II and III) showed slightly but not significant differences in albumin levels than those subjected to only RPVL or sham-operated. The MI was significantly increased in groups I, II, and III, with the MI of group III rats significantly higher than those of group I rats. CONCLUSIONS: Based on our results, we conclude that HBO treatment has the potential to diminish doxorubicin-related hepatotoxicity and improve regeneration in the injured liver.

RESUMEN

Lower gastrointestinal hemorrhage accounts for approximately 20% of gastrointestinal hemorrhage. The most common causes of lower gastrointestinal hemorrhage in adults are diverticular disease, inflammatory bowel disease, benign anorectal diseases, intestinal neoplasias, coagulopathies and arterio-venous malformations. Hemangiomas of gastrointestinal tract are rare. Mesenteric hemangiomas are also extremely rare.We present a 25-year-old female who was admitted to the emergency room with recurrent lower gastrointestinal bleeding. An intraluminal bleeding mass inside the small intestinal segment was detected during explorative laparotomy as the cause of the recurrent lower gastrointestinal bleeding. After partial resection of small bowel segment, the histopathologic examination revealed a cavernous hemagioma of mesenteric origin.Although rare, gastrointestinal hemangioma should be thought in differential diagnosis as a cause of recurrent lower gastrointestinal bleeding.

RESUMEN

BACKGROUND: Radical operation for hilar cholangiocellular carcinoma, including extended hepatic resection, seems to improve prognosis by increasing the surgical curability rate. Nevertheless, high postoperative morbidity and mortality have been reported in patients with obstructive jaundice. We describe the technique of "high hilar resection" and a modification of bilioenteric anastomosis for drainage of the multiple secondary or tertiary biliary radicals. METHODS: Ten patients with advanced hilar cholangiocellular carcinoma underwent a high hilar resection with complete parenchymal preservation, and the biliary drainage was reconstructed by a sheath-to-enteric hepaticojejunostomy. Because of the technical difficulty caused by anastomosis line in the range of the biliary sheath, a modification was performed by dividing the biliary apertures of segments 5 and 4b. RESULTS: A high hilar resection was successfully performed, and all patients were discharged from the hospital in good condition. No patient died postoperatively. The proximal resection margin was tumor-free in all patients. One patient died after 29 months of peritoneal carcinomatosis. None of the patients developed local recurrence around the hepaticojejunostomy. The remaining nine patients are alive after a mean follow-up of 28.8 months after surgery without any signs of recurrence. CONCLUSION: In highly selected patients with advanced hilar cholangiocellular carcinoma, a high hilar resection is technically safe and oncologically justifiable. In combination with our new technique of sheath-to-enteric anastomosis, the patients considerably benefit from the preservation of liver parenchyma with low postoperative morbidity and very short in-hospital stay.

RESUMEN

BACKGROUND/AIMS: The management of hydatid cyst of the liver, which is still endemic in Turkey, varies from medical treatment or percutaneous drainage to different surgical procedures. In this study, we aimed to compare the efficacy of radical surgical procedures and conservative interventions with respect to recurrence rates. METHODS: Patients who underwent any type of surgical treatment between March 1994 and March 2007 due to liver cyst hydatid were retrospectively evaluated. Data collection included demographic variables, diagnostic methods, surgical procedures, and morbidity and mortality rates. RESULTS: 242/258 (93.8%) patients with liver hydatid cyst underwent surgery, and the characteristics of 221 (91.3%) (123 female, 98 male) of these patients matched the criteria of the study. The mean age of the patients was 51 years (18-82 years). The diagnostic methods primarily included abdominal ultrasonography and computed tomography with a rate of 61.8% and magnetic resonance imaging in 12% of the patients. The patients were divided into two groups with respect to the treatment modality: Group A (n=92) - radical surgical treatment and Group B (n=129) - conservative surgery. The overall rate of recurrence was 15.3%. In Group B, this rate was 24% (n=31), whereas only 3.2% of the patients (n=3) in Group A had recurrence in the follow-up (p<0.05). The morbidity rate of the patients who underwent radical surgical modalities was also significantly lower. CONCLUSIONS: Although conservative surgical procedures are considered simpler and safer to perform, the rate of postoperative complications such as biliary fistula, residual cavity and recurrence, and cavity suppuration has been reported to be about 35%. On the other hand, radical surgery can be performed with low risk of recurrence (3.2%). We believe radical surgical procedures present a lower rate of recurrence and less morbidity, and thus should be the surgical treatment of choice for hepatic hydatid disease.

RESUMEN

The hepatic venous reconstruction is one of the corner stones of pediatric LDLT. However, problems associated with hepatic venous outflow still remain to be an issue. In this study, we aimed at comparing two methods used in hepatic venous reconstruction. Between November 1999 and December 2006, 61 consecutive left lateral segment pediatric LDLT were performed at Ege University Organ Transplant Center, and two methods were used for hepatic venous reconstruction. In the former group (group 1: 32 patients) continuous anastomosis was performed between the donor LHV and common orifice of the recipient HV. In the later group (group 2: 29 patients), the posterior wall of the anastomosis was sutured continuously while the anterior wall was sutured with interrupted sutures. HV thrombosis was detected in one patient and stenosis was detected in four patients in group 1. No hepatic venous outflow obstruction was detected in group 2 (p < 0.05). In both groups, mortality was not associated with hepatic venous outflow obstruction. As our results indicate, the novel technique used in this study is a simple and safe anastomosis procedure that has contributed into overcoming hepatic venous outflow problems in pediatric LDLT.

RESUMEN

Peri-hepatic packing procedure, which is the basic damage control technique for the treatment of hepatic hemorrhage, is one of the cornerstones of the surgical strategy for abdominal trauma. The purpose of this study was to evaluate the efficacy of the perihepatic packing procedure by comparing the outcomes of appropriately and inappropriately performed interventions. Trauma patients with liver injury were retrospectively evaluated. The patients who had undergone adequate packing were classified as Group A, and the patients who had undergone inappropriate packing, as Group B. Over a five-year period, nineteen patients underwent perihepatic packing. Thirteen of these patients were referred by other hospitals. Of 13 patients, 9 with inappropriate packing procedure due to insertion of intraabdominal drainage catheter (n=4) and underpacking (n=5) were evaluated in Group B, and the others (n=10) with adequate packing were assessed in Group A. Mean 3 units of blood were transfused in Group A and unpacking procedure was performed in the 24th hour. Only 3 (30%) patients required segment resection with homeostasis, and the mortality rate was 20% (2/10 patients). In Group B, 4 patients required repacking in the first 6 hrs. Mean 8 units of blood were transfused until unpacking procedure. The mortality rate was 44% (4/9 patients). The length of intensive care unit stay and requirement of blood transfusion were statistically significantly lower in Group A (p < 0.05). The mortality rate of this group was also lower. However, the difference between the groups for mortality rates was not statistically significant. This study emphasizes that efficacy of the procedure is one of the determinants that affects the results, and inadequate or inappropriate packing may easily result in poor outcome.

RESUMEN

BACKGROUND/AIMS: Mirizzi syndrome is an unusual presentation of prolonged cholelithiasis. This study aimed to analyze the diagnostic methods, operative strategies, and outcome of the surgical treatment of patients with Mirizzi syndrome. METHODS: We retrospectively evaluated the patients with Mirizzi syndrome treated in our General Surgery Clinic. The data collected included demographic variables, clinical presentation, diagnostic methods, surgical procedures, and postoperative complications. RESULTS: The study included 13 male and 21 female patients, with a mean age of 67.2 years. The incidence of Mirizzi syndrome was determined as 0.6% (34/5632), and type II was more frequently observed (52.9%); no patient was determined as type IV. The incidences of types I and III were 35.2% and 11.7%, respectively. Among the preoperative diagnostic evaluations, ultrasonography was the initial imaging study that was performed in all patients. Computerized tomography, magnetic resonance cholangiopancreatography, and endoscopic retrograde cholangiopancreatography were the other radiological studies. Surgical procedures included cholecystectomy for 83% of the patients with type I. The remaining cases and 14 of the type II patients (77.7%) underwent choledochotomy and T-tube insertion following cholecystectomy. Four of the patients with type II variety and all of the type III patients underwent cholecystectomy and roux-en-Y hepaticojejunostomy. All of the patients had complete recovery, with a morbidity rate of 5.8%, and there was no hospital mortality. CONCLUSIONS: The essential part of the management of patients with Mirizzi syndrome is to determine the best surgical procedure in the preoperative period. In type I patients, simple cholecystectomy is generally enough, but sometimes T-tube insertion may be required, while the cases with types II-IV require more complex surgical approach, such as cholecystectomy and bilioenteric anastomosis. Roux-en-Y hepaticojejunostomy is an appropriate procedure with good outcome.
