Are all primary omental infarcts truly idiopathic? Five case reports.

BACKGROUND: Idiopathic omental infarction (IOI) is challenging to diagnose due to its low incidence and vague symptoms. Its differential diagnosis also poses difficulties because it can mimic many intra-abdominal organ pathologies. Although hypercoagulability and thrombosis are among the causes of omental infarction, venous thromboembolism scanning is rarely performed as an etiological investigation. CASE SUMMARY: The medical records of the 5 cases, who had the diagnosis of IOI by computed tomography, were examined. The majority of the patients were male (n = 4, 80%) and the mean age was 31 years (range: 21-38). The patients had no previous abdominal surgery or a history of any chronic disease. The main complaint of all patients was persistent abdominal pain. Omental infarction was detected in all patients with contrast-enhanced computed tomography. Conservative treatment was initially preferred in all patients, but it failed in 1 patient (20%). After discharge, all patients were referred to the hematology department for thrombophilia screening. Only 1 patient applied for thrombophilia screening and was homozygous for methylenetetrahydrofolate reductase (A1298C mutation) and heterozygous for a factor V Leiden mutation. CONCLUSION: IOI should be considered in the differential diagnosis in patients presenting with progressive and/or persistent right side abdominal pain. Investigating risk factors such as hypercoagulability in patients with IOI is also important in preventing future conditions related to venous thromboembolism.

Bilateral Lumbar Hernia: A Case Report.

Lumbar hernias are a relatively uncommon occurrence, with two main categories: congenital and acquired. Some acquired hernias are spontaneous, while others are the result of secondary factors such as trauma and surgery. Bilateral primary lumbar hernia is a much rarer occurrence. Abdominal computed tomography is the gold standard for differential diagnosis of bilateral primary lumbar hernia. The treatment plan entails the closure of the defect through either open or laparoscopic methods, accompanied by the use of a suitable mesh to provide support. Nevertheless, no surgical method has yet been identified as the standard procedure for reducing the risk of relapse. We present the case of a 73-year-old female patient who presented with complaints of swelling in the left lumbar region and abdominal pain. The patient exhibited bilateral lumbar hernia. The hernial sac on the left side contained intra-abdominal organs. The diagnosis was confirmed by computed tomography. The defect on the left was subsequently closed with mesh following the dissection of the hernia sac. In this study, we present a case of bilateral lumbar hernia in the context of existing literature. The objective of this study was to assist clinicians in accurately diagnosing and appropriately managing this condition.

Imaging features and management of focal liver lesions.

Notably, the number of incidentally detected focal liver lesions (FLLs) has increased dramatically in recent years due to the increased use of radiological imaging. The diagnosis of FLLs can be made through a well-documented medical history, physical examination, laboratory tests, and appropriate imaging methods. Although benign FLLs are more common than malignant ones in adults, even in patients with primary malignancy, accurate diagnosis of incidental FLLs is of utmost clinical significance. In clinical practice, FLLs are frequently evaluated non-invasively using ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI). Although US is a cost-effective and widely used imaging method, its diagnostic specificity and sensitivity for FLL characterization are limited. FLLs are primarily characterized by obtaining enhancement patterns through dynamic contrast-enhanced CT and MRI. MRI is a problem-solving method with high specificity and sensitivity, commonly used for the evaluation of FLLs that cannot be characterized by US or CT. Recent technical advancements in MRI, along with the use of hepatobiliary-specific MRI contrast agents, have significantly improved the success of FLL characterization and reduced unnecessary biopsies. The American College of Radiology (ACR) appropriateness criteria are evidence-based recommendations intended to assist clinicians in selecting the optimal imaging or treatment option for their patients. ACR Appropriateness Criteria Liver Lesion-Initial Characterization guideline provides recommendations for the imaging methods that should be used for the characterization of incidentally detected FLLs in various clinical scenarios. The American College of Gastroenterology (ACG) Clinical Guideline offers evidence-based recommendations for both the diagnosis and management of FLL. American Association for the Study of Liver Diseases (AASLD) Practice Guidance provides an approach to the diagnosis and management of patients with hepatocellular carcinoma. In this article, FLLs are reviewed with a comprehensive analysis of ACR Appropriateness Criteria, ACG Clinical Guideline, AASLD Practice Guidance, and current medical literature from peer-reviewed journals. The article includes a discussion of imaging methods used for the assessment of FLL, current recommended imaging techniques, innovations in liver imaging, contrast agents, imaging features of common nonmetastatic benign and malignant FLL, as well as current management recommendations.

Single Stage Bilateral Adrenalectomy (Cortical-Sparing) and Pancreatectomy (Corpus-Sparing) in a Patient with Von Hippel-Lindau Disease.

Von Hippel-Lindau (VHL) disease is an autosomal dominant syndrome and affects many organs. We aim to report an adult patient with VHL disease having bilateral adrenal pheochromocytoma and multiple neuroendocrine tumors of the pancreas who was successfully treated with simultaneous function-preserving adrenalectomy and pancreatectomy. A 27-year-old woman was admitted to hospital with hypertension. The computed tomography of the abdomen revealed a solid tumor in both adrenal glands with the sizes of 12x7 cm on the right and 4x4 cm on the left. She also had two pancreatic solid masses in the head and three in the tail with varying sizes. The laboratory tests are all within normal limits except elevated 24-hour urinary metanephrine and normetanephrine. I-123 MIBG scanning showed increased uptake in both adrenal glands. Fine needle aspiration biopsy of the tumor on head of pancreas via endoscopic ultrasonography showed neuroendocrine tumor. Those findings were compatible with bilateral pheochromocytoma and multiple pancreatic neuroendocrine tumors and genetic tests revealed the mutation which confirmed the diagnosis of VHL disease. After suppression with alpha-1 inhibitor, right total, left cortical-sparing adrenalectomy, Whipple procedure for the pancreatic head lesions and spleen-preserving distal pancreatectomy were performed and pancreatic corpus was preserved. This case showed that multiple function-preserving procedures can be safely performed with oncological principles in patients with VHL disease.

Carcinoembryonic antigen in the diagnosis, treatment, and follow-up of focal liver lesions.

In this editorial review, we comment on the article published in the recent issue of the World Journal of Gastrointestinal Surgery. Carcinoembryonic antigen (CEA) is a fetal glycoprotein and can be secreted in very small amounts from healthy adults after birth. CEA is widely used not only for diagnostic tumor markers but also importantly for the management of some gastrointestinal tumors. The most common clinical use is surveillance for the monitoring of colorectal carcinoma. However, CEA can become elevated in several malign or benign characterized pathologies. Serum CEA level may vary depending on the location of the lesion, whether it metastasizes or not, and its histopathological characteristics. It has been determined that cases with high preoperative CEA have a more aggressive course and the risk of metastasis to the lymph tissue and liver increases. In this editorial review, we focused on evaluating the role of CEA in clinical practice with a holistic approach, including the diagnostic and prognostic significance of CEA in patients with focal liver lesions, the role of CEA in follow-up after definitive surgery, and also hepatic resection for metastasis, and the management of all patients with raised CEA.

Venous reconstruction thrombosis after pancreaticoduodenectomy with superior mesenteric/portal vein resection due to pancreatic cancer: an 8 years single institution experience.

BACKGROUND: Superior mesenteric/portal vein reconstruction (SMPVR) thrombosis remains a challenging complication following pancreaticoduodenectomy concomitant with venous resection. In this context, we aimed to present our SMPVR experiences and identify potential clinicopathological factors that increased SMPVR thrombosis. METHODS: A total of 33 patients who underwent SMPVR during pancreaticoduodenectomy were analyzed. Of these, 26 patients who experienced pancreatic head ductal adenocarcinoma met our inclusion criteria. Patients' data were compared as classified by SMPVR type and the development of SMPVR thrombosis. All interposition grafts were Dacron in this cohort. RESULTS: Types of SMPVR included: tangential resection with primary repair (n = 12); segmental resection with splenic vein preservation and either primary anastomosis (n = 8) or 14 mm tubular Dacron grafting (n = 1); segmental resection with splenic vein division either 14 mm tubular Dacron grafting (n = 2) or 14/7 mm 'Y'-shaped Dacron grafting (n = 3). A total of four patients having 14/7 mm 'Y'-shaped (n = 3) and 14 mm tubular Dacron (n = 1) developed SMPVR thrombosis (p = .001). Dacron grafting (p = .001) and splenic vein division (p = .010) were associated with SMPVR thrombosis. The median time to detection of SMPVR thrombosis was 4.3 months (2.5-21.0 months). The median follow-up time was 12.2 months (3.0-45 months). CONCLUSIONS: During pancreaticoduodenectomy for pancreatic head ductal carcinoma, extended venous resection requiring SMPVR with 'Y'-shaped and use of Dacron interposition grafts appeared to be associated with the development of SMPVR thrombosis. This result warrants further investigations.

Role of contrast-enhanced serial/spot abdominal X-rays in perioperative follow-up of patients undergoing abdominal surgery: An observational clinical study.

BACKGROUND: Many imaging methods such as ultrasonography, computed tomography (CT), magnetic resonance imaging, and endoscopy are used to identify the problems or complications that occur in the perioperative period and to determine the appropriate therapeutic approach. Specialists at surgical clinics and intensive care units sometimes need diagnostic procedures that can give quick results or reveal unexpected results. In particular, rapid on-site evaluation of patients followed under intensive care conditions has several advantages. AIM: To determine the problems developing in patients in the perioperative period by contrast-enhanced abdominal X-ray (CE-AXR), revealing their current status or defining the effectiveness of CE-AXR. METHODS: The files of the patients who underwent hepatopancreatobiliary or upper gastrointestinal surgery, whose CE-AXR film was taken, were reviewed retrospectively. Abdominal X-ray radiographs taken after ingestion of a water-soluble contrast agent (iohexol, 300 mg, 50 cc vial) and its application in a drain, nasogastric tube, or stent were evaluated. The contribution of the data obtained in patients who underwent CE-AXR to the diagnosis, follow-up, and treatment processes and the effectiveness of the application were investigated. RESULTS: CE-AXR was applied to 131 patients in our clinic, most of whom underwent hepatopancreatobiliary or upper gastrointestinal surgery. It was determined that the data obtained from CE-AXR films taken in 98 (74.8%) of the patients contributed to the diagnosis, treatment, and follow-up expectations and positively affected the clinical processes. CONCLUSION: CE-AXR is a simple procedure that can be applied anywhere, especially in intensive care patients and at bedside, with a portable X-ray device. The simplicity of the procedure, less radiation exposure for the patients, less time wastage, reduction in the CT and endoscopy procedure burden and costs, quick results, rapid assessment of the situation, and enabling the monitoring of processes with repetitive procedures are important advantages. X-rays taken will be useful in terms of being a reference value during the follow-up period of the patient and determining the situation in medicolegal processes.

Factors affecting complications and clinical outcome in patients with Mirizzi syndrome. Single center experience.

Mirizzi syndrome (MS) is a syndrome that causes chronic destructive and fibrotic changes because of compression and inflammation in the main biliary tract. MS remains to be a serious problem due to its high morbidity. In this study, it is aimed to evaluate the diagnostic tools, risk factors and clinical output data we apply to our patients with MS in the light of the literature. We retrospectively analyzed the data of patients treated for MS in the last decade in our hospital, where an average of 1350 cholecystectomies are performed annually. Clinical, laboratory and imaging data obtained from patients' files were evaluated. We identified 76 patients with MS and classified them as type 1-5 according to the Csendes classification. Abdominal pain, fever and jaundice were the most common symptoms. 42 patients had type 1 and 2 MS. Mirizzi syndrome was diagnosed with preoperative radiological imaging methods in 24 of the patients. In 41 of the patients, the surgery first started laparoscopically, and then turned to laparotomy in 39 patients. Other 35 patients were operated with conventional methods. In 11 cases, subtotal cholecystectomy was performed Early diagnosis and surgical treatment of symptomatic cholelithiasis decrease the frequency of MS. Inflammation criteria can be used as an indicative biomarker. The patient's history, USG, ERCP and MRCP findings are currently the most important diagnostic tools. Releasing the gallbladder with the "fundus first" approach can reduce the risk of trauma. In cases where MS is suspected, a stent placed with ERCP decrease bile duct trauma. KEY WORDS: Complication, Diagnosis, Mirizzi's syndrome, Prediction, Treatment.

Management of hepatic artery trauma during hepato-pancreato-biliary procedures: Evolving approaches, clinical outcomes, and literature review.

BACKGROUND: One of the most feared complications of surgeons dealing with hepato-pancreato-biliary (HPB) surgery is hepatic artery (HA) injury. Here, we aimed to evaluate our clinical experience (laceration, transection, ligation, and resection) related to HA traumas, which have serious morbidity and mortality risks, in the light of literature data and the rapidly evolving management methods in recent years. METHODS: The files of 615 patients who were operated on for HPB pathologies in the last decade, in our hospital, were retrospectively reviewed. Clinical, laboratory, and imaging data obtained from patients' files were evaluated. RESULTS: A total of 13 HA traumas were detected, eight of them had HA injury and five had planned HA resection. During the post-operative follow-up period, liver abscess, anastomotic leakage, and late biliary stricture were detected. CONCLUSION: Complications and deaths due to HA injury or ligation are less common today. The risk of complications increases in patients with hemodynamically unstable, jaundice, cholangitis, and sepsis. Revealing the variations in the pre-operative radiological evaluation and determining the appropriate approach plan will reduce the risks. In cases where HA injury is detected, arterial flow continuity should be tried to be maintained with primary anastomosis, arterial transpositions, or grafts.

Clinical outcome of gallstone ileus; a single-centre experience of case series and review of the literature.

BACKGROUND: Gallstone ileus (GI) is a rare entity which is seen in 0.5% of patients with cholelithiasis. In this study, we aimed to share our clinical approach to GI, to present our long-term results and to draw clinicians' attention to this rare entity. MATERIALS AND METHODS: This study included 11 patients with GI whose medical records were evaluated retrospectively. RESULTS: Majority of the 11 patients were female (63.7%, n:7) and the mean age was 71.9 ± 14.10 (range: 50-91). Most common presenting complaints were vomiting (n: 9) and abdominal pain (n: 9). The mean interval from the onset of symptoms to the hospital admission was 3.8 ± 0.75 (range 3-5) days. Rigler triad in abdominal computed tomography (CT) was detected in all cases. Enterolithotomy, one-step procedure and conservative treatment were performed in five (45.4%), four (36.3%) and two (18.1%) patients, respectively. Enterolithotomy group was found to have higher risk according to American Society of Anesthesiologists (ASA) classification, shorter operation time and less intraoperative blood loss. CONCLUSION: Although enterolithotomy is the first choice for patients with GI, one-step procedure should be kept in mind as a more advantageous technique in low-risk patients.

Is omentectomy necessary in the treatment of benign or malignant abdominal pathologies? A systematic review.

BACKGROUND: The omentum is an organ that is easily sacrificed during abdominal surgery. The scope of omentectomy and whether a routine omentectomy should be performed are still unknown. AIM: To review the literature in order to determine the physiological functions of the omentum and the roles it plays in pathological events in order to reveal the necessity for removal and preservation of the omentum. METHODS: A clinical review of the English language literature based on the MEDLINE (PubMed) database was conducted using the keywords: "abdomen", "gastrointestinal", "tumor", "inflammation", "omental flap", "metastasis", "omentum", and "omentectomy". In addition, reports were also identified by systematically reviewing all references in retrieved papers. RESULTS: The omentum functions as a natural barrier in areas where pathological processes occur in the abdominal cavity. The omentum limits and controls inflammatory and infectious pathologies that occur in the abdomen. It also aids in treatment due to its cellular functions including lymphatic drainage and phagocytosis. It shows similar behavior in tumors, but it cannot cope with increasing tumor burden. The stage of the disease changes due to the tumor mass it tries to control. Therefore, it is considered an indicator of poor prognosis. Due to this feature, the omentum is one of the first organs to be sacrificed during surgical procedures. However, there are many unknowns regarding the role and efficacy of the omentum in cancer. CONCLUSION: The omentum is a unique organ that limits and controls inflammatory processes, foreign masses, and lesions that develop in the abdominal cavity. Omental flaps can be used in all anatomical areas, including the thorax, abdomen, pelvis, and extremities. The omentum is an organ that deserves the title of the abdominal policeman. It is generally accepted that the omentum should be removed in cases where there is tumor invasion. However, the positive or negative contribution of omental resection in the treatment of abdominal pathologies should be questioned.

Dealing with hepatic artery traumas: A clinical literature review.

BACKGROUND: The hepatic artery (HA) is one of the most threatened vascular structures during hepatopancreatobiliary (HPB) surgeries and interventional procedures. It can be affected by many clinical pictures, especially tumors, due to its anatomical position and neighborhood. AIM: To reveal the evolution and recent developments in the management of HA traumas in the light of the literature. METHODS: In this article, 100 years of MEDLINE (PubMed) literature and articles including cases and series of HA injuries were reviewed, and the types of injury occurrence, treatment, and related complications and their management were compiled. RESULTS: The risk of HA injury increases during cholecystectomies and pancreatoduodenectomies, among the most common operations. HA anatomy shows anomalies in approximately 15%-25% of the cases, further increasing this risk. The incidence of HA injury is not precisely known. Approaches that have evolved in recent years in managing patients with HA injury (laceration, transection, ligation, resection) with severe morbidity and mortality risk are reviewed in light of the current literature. CONCLUSION: In conclusion, complications and deaths due to HA injury are less common today. The risk of complications increases in patients with hemodynamic instability, jaundice, cholangitis, and sepsis. Revealing the variations in the preoperative radiological evaluation will reduce the risks. In cases where HA injury is detected, arterial flow continuity should be tried to maintain with primary anastomosis, arterial transpositions, or grafts. In cases where bile duct injury develops, patients should be directed to HPB surgery centers, considering the possibility of accompanying HA injury. Large-scale and multicentric studies are needed to understand better the early and long-term results of HA ligation and determine preventive procedures.

Clinical Analysis of Pancreaticoduodenectomies for Benign Pathologies.

OBJECTIVE: To evaluate the clinical, laboratory and imaging data of patients who underwent pancreatoduodenectomy (PD) for proven benign pathologies. STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: Department of General Surgery, Izmir Katip Celebi University, School of Medicine, Turkey between January 2015 and June 2020. METHODOLOGY: All patients who underwent PD, and were found to be benign histopathologically, were included in the study. Patients who had to undergo PD due to trauma during operations performed for other reasons, were also included in the study. The data was collected as per objective. RESULTS: Diagnosis of benign pathologies was made histopathologically in 27 of the 248 patients (10.89%). It was found that 8 of 17 patients, who had biopsy in the preoperative period, were operated with a pre-diagnosis of malignancy, nine were performed PD due to accompanying clinical findings despite the detection of non-diagnostic cytology, and ten patients were taken into surgery; because of the malignancy risk could not be ruled out. CONCLUSION: Patients with benign pathology were found to have better parameters of CRP and total bilirubin. PD was performed in patients with mass in the pancreas; and whose cancer risk could not be ruled out. To reduce PD due to benign causes, patients with undiagnosed lesions should be evaluated with a multidisciplinary approach, and diagnostic tools should be cross-checked. PET/CT may also be useful in the differential diagnosis. Key Words: Benign, Diagnosis, Pancreas, Pancreaticoduodenectomy, Pathology.

Analysis of the Factors Affecting Survival in the Patients who Underwent Curative-Intent Gastrectomy due to Gastric Adenocarcinoma.

OBJECTIVES: Gastric cancer is the fifth most common cancer and the third most common cause of cancer-related deaths in the world. In this study, we aimed to evaluate the impact of clinicopathological factors on overall survival in the patients who underwent curative-intent gastrectomy due to gastric adenocarcinoma. METHODS: The medical records of 644 patients who underwent gastrectomy between January 2007 and January 2017 in our clinic were retrospectively reviewed. Among these patients, 359 patients were included in this study. The impact of several prognostic factors on survival was investigated. RESULTS: The mean age was 59.2±11.6 (29-83). Male/female ratio was 2.12. The median follow-up time was 19 months (CI=10.1-31.1). Median overall survival was 23±2.3 months (CI=18.3-27.6). Splenectomy, R1 (microscopically incomplete) resection, and advanced stage were independent risk factors for poor prognosis. CONCLUSION: R1 resection, splenectomy, and advanced TNM stage were associated with poor prognosis in gastric cancer. Splenectomy should be avoided in the absence of direct invasion of the tumour or metastasis of lymph nodes on splenic hilum to prevent postoperative infectious complication-related mortality.

The role of portoenterostomy in the treatment of patients with multiple bile duct trauma: Case series and review of the literature.

BACKGROUND: Hepaticojejunostomy is a challenging and complex procedure to be administered with the confidence, in conditions which contain a large number of bile duct damaged by benign pathologies or major bile duct trauma. METHODS: Here, our clinical series of portoenterostomy (PE), in which we applied in patients who had aggressive hilar dissection for hilar benign biliary pathologies and major bile duct traumas during laparoscopic cholecystectomies were discussed in the light of the literature. The PE procedure was performed in the presence of three or more bile ducts that could not be merged. The classic Roux-en-Y style hepaticojejunostomy was performed to prevent postoperative ascending cholangitis. The ropeway system was used when sewing. 6-8 stitches were laid on the back or anterior wall and the sutures were tied on the outside. Thin-long silicone stents placed in the small diameter (2 mm) bile ducts coinciding with the anastomosis line were extended into the jejunum. RESULTS: This study included six patients who underwent PE between 2015-2019. Five of the cases were male and one was female and the mean age was 70.33 years. Hepaticojejunostomy was performed in two of the four cases with biliary trauma, but the endoscopic and surgical revision was performed due to developing strictures and bile flow was corrected with stents. In these two cases coming from the external center, PE was applied to multiple bile ducts resulting from aggressive hilar dissection. In two patients who developed major biliary tract trauma (Strasberg-Bismuth-E4) at our hospital underwent PE in the same session. In the other two cases, PE was performed due to a large number of bile ducts caused by benign pathology-related complications (Mirizzi syndrome, Type 4). The mean follow-up period for six patients was 20.1 months (range 11 to 37 months). CONCLUSION: Portoenterostomy can be performed as a salvage procedure in cases where multiple biliary tracts occur and hepaticojejunostomy is inadequate. PE can be safely used in selected cases that had benign pathologies, major bile duct trauma, in the presence of intense fibrosis, inflammation, very thin bile ducts and more fragile tissues in the liver hilum. PE should be performed in centers with surgeons experienced in hepatobiliary surgery. However, to better understand the efficacy of PE, large multicentric clinical series and patient follow-up are required.

The Role of Portoenterostomy with Aggressive Hilar Dissection in Biliary Tract Tumors: Report of Case Series and Review of the Literature.

Hepaticojejunostomy is a challenging and complex procedure to be done with confidence in conditions that contain a large number of segmental bile ducts. Portoenterostomy can be defined as the joining of multiple bile ducts into a single cavity using segmenter bile duct ends, stents, and surrounding connective tissues. During surgery, in cases with advanced stage biliary tract tumors that cannot be performed hepatectomy, after aggressive dissections to provide a negative surgical margin, a large number of segmental bile ducts can be revealed and needs to ensure the continuity of bile flow. Here, our clinical series of portoenterostomy (PE) in which we applied in patients who had aggressive hilar dissection and resection for hilar cholangiocarcinomas and biliary tract tumors were discussed. The study included 15 patients who underwent PE for biliary tract tumors and hilar cholangiocarcinomas between 2015 and 2019. Six of the patients had a tumor-negative surgical margin, with a mean follow-up of 14.4 months (range 2 to 28 months). Nine of the patients had a tumor-positive surgical margin, with a mean follow-up of 7.7 months (range 2 to 17 months). Portoenterostomy instead of hepaticojejunostomy in small and multiple biliary radicles and bile duct cancers has been successfully performed in 15 patients of bile duct cancer and Klatskin tumor. In the presence of active inflammation, fibrosis, major bile duct trauma, and thin bile duct radicles, this method, which is described in detail, provides an excellent salvage surgical procedure with less morbidity.

Is subtotal cholecystectomy safe and feasible? Short- and long-term results.

BACKGROUND: Cholecystectomy is one of the most commonly performed surgical procedures. However, it may result in some unpleasant conditions such as bile duct injury (BDI), bile leak, and vessel injury. Subtotal cholecystectomy (SC), which has been introduced as an alternative method for reducing the complication rates, has been reported to have lower risk of BDI when compared to total cholecystectomy. This study aimed to evaluate the indications for SC, its early and late complications and their management, and the risk factors affecting the bile leak. METHODS: Fifty-seven patients who underwent SC were included in the study, and their medical records were retrospectively reviewed. RESULTS: Thirty-three patients were male (57.9%) and the mean age was 64.84 ± 11.35 (range: 29-86). All patients had at least one episode of cholecystitis. Forty-seven (82.5%) patients underwent surgery under emergency conditions. Postoperative bile leak/fistula, surgical site infection, and fluid collection were developed in 12 (21.1%), eight (14%), and six (10.5%) patients, respectively. Leaving the remnant tissue pouch open, presence of comorbidity and emergency operative condition were found to increase the risk of leak development (P < .001). During the average follow-up of 49 months (range: 13-98), symptomatic choledocholithiasis, symptomatic gallstones in the remnant tissue, and incisional hernia were detected within the first year of surgery in three (5.3%), four (7%), and seven (12.3%) patients, respectively. CONCLUSIONS: Although SC is not an equivalent to total cholecystectomy, its vital benefit of lowering the risk of BDI should be considered in difficult cases.

Relation of computed tomography features of the pancreatic tissue and development of pancreatic fistula after pancreaticoduodenectomy.

BACKGROUND: Pancreatic density and steatosis detected in pre-operative computed tomography (CT) may be a risk factor for PF development after pancreatoduodenectomy (PD). There is insufficient data available on the relationship between PF and atherosclerosis in pancreatic vasculature of pancreatitis. This study aims to investigate whether PF development in patients undergoing PD can be predicted by preoperative CT findings. MATERIAL-METHOD: Pancreas and spleen densities were measured on non-contrast CT images and pancreatic index (PI) was calculated to detect pancreatic steatosis. Pancreatic density and Wirsung diameter (WD) were measured on portal venous phase. Pancreatic fistulae were identified as biochemical leak (BL), grade B and grade C using ISGPF classification. The findings were compared between the fistula and non-fistula groups and ISGPF subgroups. RESULTS: Of 148 patients, PF was detected on 31 (20.9%). In PF group, mean pancreatic density and PI were significantly lower than non-PF group, while pancreatic steatosis was detected at a higher rate. The WD was significantly narrower in the PF group. No significant relationship was found between the development of PF and the findings of atherosclerosis in the CT and SMA or acute pancreatitis. There was no significant difference between the PF subgroups for pancreas density. CONCLUSION: In preoperative CT examinations, measuring the pancreatic density, PI index and WD can be used as a noninvasive quantitative method to predict the possibility of postoperative PF development.

Endoscopic and surgical management of iatrogenic biliary tract injuries.

BACKGROUND: Iatrogenic biliary tract injury (BTI) is a rare complication but has high risks of morbidity and mortality when it is not early noticed. Although the treatment varies depending on the size of injury and the time until the injury is noticed, endoscopic and percutaneous interventions are usually sufficient. However, it should be remembered that these interventions may cause major complications in the following years, such as biliary stricture, recurrent episodes of cholangitis and even cirrhosis. In this paper, we aimed to present our approach to BTI following cholecystectomy and our treatment management in the light of the literature. METHODS: The medical records of 105 patients who were treated for BTI between January 2015 and July 2019 were evaluated retrospectively. The majority of the patients consisted of the patients who underwent cholecystectomy at an external medical center and were referred to our clinic due to biliary leakage (BL). Patients were grouped according to Strasberg classification determined by the place of leakage. RESULTS: Among 105 patients included in this study, 55 were male, and 50 were female. Mean age was 55.2±16.26 years (range, 21-93 years). According to Strasberg classification, type A, B, C, D and E injuries were detected in 57, 1, 3, 29 and 15 patients, respectively. Eighty-five patients were successfully treated with endoscopic and percutaneous interventions, while 20 patients underwent surgery. CONCLUSION: In all patients with suspected BTI, a detailed screening and appropriate treatment provide a significant decline in morbidity and mortality. Therefore, early diagnosis is very important for both early and late outcomes.
