Central Pancreatectomy: Balancing between the Favorable Functional Results and the Increased Associated Morbidity.

Introduction Central pancreatectomy (CP) represents an organ-preserving type of pancreatic resection. The procedure has been associated with improved long-term functional results, but increased postoperative morbidity rates, compared with the more radical resection types. The purpose of the present study was to present the outcomes of three consecutive CPs performed in our department. Materials and Methods Between January 2021 and January 2022, three patients (A, B, and C) were submitted to a CP in our department. Relevant patient data including data of the detailed preoperative assessment, operations notes, and recovery charts were prospectively collected and reviewed for all subjects. A scheduled follow-up, at the outpatient clinic, was conducted to assess the long-term functional results. Results The postoperative course of patient A, a 56-year-old male, was complicated by a grade C postoperative pancreatic fistula that required a reoperation. Patient B, a 66-year-old female, developed a biochemical leak that resolved spontaneously while patient C, a 64-year-old male, had a completely uneventful recovery. The length of hospital stay for the three patients was 24, 12, and 8 days, respectively. Regarding the long-term results, patient B was lost to follow-up while both patient A and C were followed up, as outpatients, 21 and 10 months after the operation. During follow-up, in patient A, we did not record the presence of symptoms consistent with pancreatic exocrine insufficiency, the hemoglobin A1C (HbA1C) levels were 7.1% while no additional medications were needed to be prescribed to maintain the glycemic control following surgery. In patient C, a significant weight loss was recorded (body mass index reduction of 11 kg/m 2 ) without however the presence of malabsorption-specific symptoms. The HbA1C levels were 7.7% and optimal glycemic control was achieved with oral antiglycemic agents alone. Conclusion CP should be regarded as a type of pancreatic resection with certain and very limited oncological indications. An approach of balancing the advantages out of the superior postoperative functional results with the drawbacks of the increased procedure-associated morbidity could highlight the patient group that could potentially experience benefits out of this limited type of resection.

Comparison of ointment-based agents after excisional procedures for hemorrhoidal disease: a network meta-analysis of randomized controlled trials.

INTRODUCTION: Efficient postoperative pain control is important after hemorrhoidal surgery. Although several locally applied medications have been used, current evidence regarding the optimal strategy is still conflicting. This network meta-analysis assessed analgesic efficacy and safety of the various topical medications in patients submitted to excisional procedures for hemorrhoids. METHODS: The present study followed the Cochrane Handbook for Systematic Reviews of Interventions and the PRISMA guidelines. The last systematic literature screening was performed at 15 June 2023. Comparisons were based on a random effects multivariate network meta-analysis under a Bayesian framework. RESULTS: Overall, 26 RCTs and 2132 patients were included. Regarding postoperative pain, EMLA cream (surface under the cumulative ranking curve (SUCRA) 80.3%) had the highest ranking at 12-h endpoint, while aloe vera cream (SUCRA 82.36%) scored first at 24 h. Metronidazole ointments had the highest scores at 7 and 14 days postoperatively. Aloe vera had the best analgesic profile (24-h SUCRA 84.8% and 48-h SUCRA 80.6%) during defecation. Lidocaine (SUCRA 87.9%) displayed the best performance regarding overall morbidity rates. CONCLUSIONS: Due to the inconclusive results and several study limitations, further RCTs are required.

From Classic Whipple to Pylorus Preserving Pancreaticoduodenectomy and Ultimately to Pylorus Resecting - Stomach Preserving Pancreaticoduodenectomy: A Review.

Pancreaticoduodenectomy is the procedure of choice for benign or malignant tumors of the periampullary region. The preservation of the pylorus has been established as the mostly utilized approach during pancreaticoduodenectomy among the majority of specialized, in the surgical treatment of pancreatic cancer, centers worldwide. The factors that influenced this predilection are the shorter operation times, the less intraoperative blood loss, the decreased technical difficulty, and the quite similar short- and long-term outcomes compared to the classic Whipple. However, there is a notable trend in the literature highlighting the increased incidence of delayed gastric emptying following pylorus preserving pancreaticoduodenectomy. Among other factors, pylorus dysfunction attributable to the surgical maneuvers has been implemented in the etiology of this complication. In an attempt to overcome this limitation of the pylorus preserving pancreaticoduodenectomy, pylorus resecting pancreaticoduodenectomy with the preservation of the stomach was proposed. In theory, pylorus resecting pancreaticoduodenectomy could maintain the advantages of organ sparing surgery, but at the same time guarantee a more seamless gastric emptying. Only three RCTs, to date, aimed to evaluate the approach with only one reporting results in favor of the pylorus resecting pancreaticoduodenectomy in regard to the incidence of delayed gastric emptying. Further well-designed prospective randomized studies are needed for an accurate assessment of the true role of each of these surgical alternatives on the treatment of pancreatic cancer.

BILE: A Literature Review Based Novel Clinical Classification and Treatment Algorithm of Iatrogenic Bile Duct Injuries.

PURPOSES: The management of patients with iatrogenic bile duct injuries (IBDI) is a challenging field, often with dismal medico legal projections. Attempts to classify IBDI have been made repeatedly and the final results were either analytical and extensive but not useful in everyday clinical practice systems, or simple and user friendly but with limited clinical correspondence approaches. The purpose of the present review is to propose a novel, clinical classification system of IBDI by reviewing the relevant literature. METHODS: A systematic literature review was conducted by performing bibliographic searches in the available electronic databases, including PubMed, Scopus, and the Cochrane Library. RESULTS: Based on the literature results, we propose a five (5) stage (A, B, C, D and E) classification system for IBDI (BILE Classification). Each stage is correlated with the recommended and most appropriate treatment. Although the proposed classification scheme is clinically oriented, the anatomical correspondence of each IBDI stage has been incorporated as well, using the Strasberg classification. CONCLUSIONS: BILE classification represents a novel, simple, and dynamic in nature classification system of IBDI. The proposed classification focuses on the clinical consequences of IBDI and provides an action map that can appropriately guide the treatment plan.

Averting an Unnecessary Revision of a Roux-en-Y Hepaticojejunostomy by Surgically Creating an Access Point for the Endoscopic Assessment of the Anastomosis: A Report of a Case.

Introduction: Primary sclerosing cholangitis sets the scene for several pathologies of both the intrahepatic and the extrahepatic biliary tree. Surgical treatment, when needed, is almost unanimously summarized in the creation of a Roux-en-Y hepaticojejunostomy, a procedure with a relatively high associated failure rate. Presentation of case: A 70-year-old male, diagnosed with primary sclerosing cholangitis, was submitted to a Roux-en-Y hepaticojejunostomy due to a dominant stricture of the extrahepatic biliary tree. Recurrent episodes of acute cholangitis dictated a workup in the direction of a possible stenosis at the level of the anastomosis. The imaging studies were inconclusive while both the endoscopic and the transhepatic approach failed to assess the status of the anastomosis. A laparotomy, with the intent to revise a high suspicion for stenosis hepaticojejunostomy, was decided. Intraoperatively, a decision to assess the hepaticojejunostomy prior to the scheduled surgical revision, via endoscopy, was made. In this direction, an enterotomy was made on the short jejunal blind loop in order to gain luminal access and an endoscope was propelled through the enterotomy towards the biliary enteric anastomosis. Results: The inspection of the anastomosis under direct endoscopic vision showed no evidences of stenosis and averted an unnecessary, under these circumstances, revision of the anastomosis. Conclusions: The surgical revision of a Roux-en-Y hepaticojejunostomy is a highly demanding operation with an increased associated morbidity, and it should be reserved as the final resort in the treatment algorithm. An approach of utilizing surgery to facilitate the endoscopic assessment prior to proceeding to the surgical revision of the anastomosis appears justified.

Isoperistaltic vs antiperistaltic anastomosis after right hemicolectomy: A comprehensive review.

To optimize the efficiency of ileocolic anastomosis following right hemicolectomy, several variations of the surgical technique have been tested. These include performing the anastomosis intra- or extracorporeally or performing a stapled or hand-sewn anastomosis. Among the least studied is the configuration of the two stumps (i.e., isoperistaltic or antiperistaltic) in the case of a side-to-side anastomosis. The purpose of the present study is to compare the isoperistaltic and antiperistaltic side-to-side anastomotic configuration after right hemicolectomy by reviewing the relevant literature. High-quality literature is scarce, with only three studies directly comparing the two alternatives, and no study has revealed any significant differences in the incidence of anastomosis-related complications such as leakage, stenosis, or bleeding. However, there may be a trend towards an earlier recovery of intestinal function following antiperistaltic anastomosis. Finally, existing data do not identify a certain anastomotic configuration (i.e., isoperistaltic or antiperistaltic) as superior over the other. Thus, the most appropriate approach is to master both anastomotic techniques and select between the two configurations based on each individual case scenario.

The role of the Rafaelo procedure in the management of hemorrhoidal disease: a systematic review and meta-analysis.

BACKGROUND: The aim of this study was to summarize the current evidence regarding the role of the Rafaelo procedure in the management of hemorrhoidal disease (HD). METHODS: This study was based on the Cochrane Handbook for Systematic Reviews of Interventions and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A literature search was performed (Medline, Scopus, CENTRAL, and Web of Science) from inception to 25/09/2022. Grey literature databases were also reviewed. The primary endpoint was the pooled complications rate of the Rafaelo procedure in patients with HD. Secondary endpoints included short- (bleeding, pain, thrombosis, necrosis, urinary retention, fever, oedema, anal fissure, and readmission) and long-term (stenosis, meteorism, constipation, anal tags, anal hyposensibility, reoperation, and recurrence) postoperative complication rates. Both prospective and retrospective studies were considered. Quality evaluation was performed via the ROBINS-I tool. Certainty of Evidence was based on the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology. RESULTS: Overall, 6 non-randomized studies and 327 patients were included. The overall complication rate was 17.6% (95% CI 8.8-26.3%). Short-term complications were bleeding (7.5%, 95% CI 2.5-12.5%), thrombosis (2.2%, 95% CI 0.4-4.8%), and pain (1.6%, 95% CI 0.2-3.3%). Reoperation and recurrence rates were 1.8% (95% CI 0.3-3.4%) and 4.8% (95% CI 1.2-8.4%), respectively. A significant improvement in the presenting symptoms was noted. Method approval and patient satisfaction rates were 89.1% (95% CI 81.7-96.6%) and 95% (95% CI 89.8-100%), correspondingly. Overall CoE was "Very Low". CONCLUSIONS: Further randomized controlled trials are required to delineate the exact role of the Rafaelo procedure in HD.

Milligan-Morgan hemorrhoidectomy vs. hemorrhoid artery ligation and recto-anal repair: a comparative study.

BACKGROUND: Several surgical techniques for the treatment of hemorrhoidal disease (HD) have been proposed. However, the selection of the most proper technique for each individual case scenario is still a matter of debate. The purpose of the present study was to compare the Milligan-Morgan (MM) hemorrhoidectomy and the hemorrhoidal artery ligation and rectoanal repair (HAL-RAR) technique. METHODS: A retrospective analysis of the prospectively collected database of patients submitted to HD surgery in our department was conducted. Patients were divided into two groups, the MM group and the HAL-RAR group. Primary end points were recurrence rates and patients' satisfaction rates. The Unpaired t test was used to compare numerical variables while the x2 test for categorical variables. RESULTS: A total of 124 patients were identified, submitted either to HAL-RAR or MM hemorrhoidectomy. Eight (8) patients were lost to follow up and were excluded from the analysis. Of the remaining 116 patients, 69 patients (54 males and 15 females-male / female ratio: 3.6) with a median age of 47 years old (range 18-69) were included in the HAL-RAR group while 47 patients (40 males and 7 females-male / female ratio: 5.7) with a median age of 52 years old (range 32-71) comprised the MM group. At a median follow up of 41 months (minimum 24 months-maximum 72 months), we recorded 20 recurrences (28.9%) in the HAL-RAR group and 9 recurrences in the MM group (19.1%) (p 0.229). The mean time from the procedure to the recurrence was 14.1 ± 9.74 months in the HAL-RAR group and 21 ± 13.34 months in the MM group. Patients with itching, pain or discomfort as the presenting symptoms of HD experienced statistically significantly lower recurrences (p 0.0354) and reported statistically significantly better satisfaction rates (6.72 ± 2.15 vs. 8.11 ± 1.99-p 0.0111) when submitted to MM. In the subgroup of patients with bleeding as the presenting symptom, patients satisfaction rates were significantly better (8.59 ± 1.88 vs. 6.45 ± 2.70-p 0.0013) in the HAL-RAR group. CONCLUSIONS: In patients with pain, itching or discomfort as the presenting symptoms of HD, MM was associated with less recurrences and better patients satisfaction rates compared to HAL-RAR. In patients with bleeding as the main presenting symptom of HD, HAL-RAR was associated with better patients' satisfaction rates and similar recurrence rates compared to MM.

Colorectal Cancer Liver Metastases: Is an R1 Hepatic Resection Accepted?

Metastatic colorectal cancer is associated with a rather dismal 5-year overall survival. The liver is the most commonly affected organ. Improved 5-year survival rates after successful hepatic resections for metastases confined to the liver have been reported. Certainly, a hepatectomy that results in an incomplete tumor resection, in terms of leaving macroscopic residual tumor in the future liver remnant, is not associated with survival benefits. However, the prognostic implications of a microscopically positive surgical margin or a clear margin of less than 1 mm (R1) on pathology are debatable. Although it has been a field of extensive research, the relevant literature often reports contradictory results. The purpose of the present study was to define, assess the risk factors for, and, ultimately, analyze the effect that an R1 hepatic resection for colorectal cancer liver metastases might have on local recurrence rates and long-term prognosis by reviewing the relevant literature. Achieving an R0 hepatic resection, optimally with more than 1 mm of clear margin, should always be the goal. However, in the era of the aggressive multimodality treatment of liver metastatic colorectal cancer, an R1 resection might be the cost of increasing the pool of patients finally eligible for resection. The majority of literature reports have highlighted the detrimental effect of R1 resections on local recurrence and overall survival. However, there are indeed studies that degraded the prognostic handicap as a consequence of an R1 resection in selected patients and highlighted the presence of RAS mutations, the response to chemotherapy, and, in general, factors that reflect the biology of the disease as important, if not the determinant, prognostic factors. In these patients, the aggressive disease biology seems to outperform the resection margin status as a prognostic factor, and the recorded differences between R1 and R0 resections are equalized. Properly and accurately defining this patient group is a future challenge in the field of the surgical treatment of colorectal cancer liver metastases.

White spirit poisoning: An unusual cause of hepatic portal venous gas.

Traditionally, the presence of air within the hepatic portal venous system has been considered a rather ominous sign as it has been associated with conditions of increased associated morbidity and mortality such as bowel ischemia and intraabdominal sepsis. However, benign conditions, not requiring any particular intervention, have been implemented in the etiology, as well. In the present report, we present the case of the accidental ingestion of white spirit as a rather unusual cause of hepatic portal vein gas. A 32-year-old, otherwise healthy, male was admitted to the emergency department following the accidental ingestion of a "sip," approximately 15 ml, of white spirit. The patient was complaining of nausea and upper abdominal pain that started soon after the ingestion of caustic agent. An imaging investigation with a computed tomography scan (CT) of the abdomen revealed the presence of hepatic portal vein gas along with a diffuse edema of the gastric wall at the site of the lesser curvature. A follow-up CT, 2 days after the admission, revealed no evidence of hepatic portal venous gas. Based on the patient's good general condition, an expectant management was decided. No intervention was required, oral feeding was recommenced after 6 days of fasting and the patient was discharged 8 days after the admission. Hepatic portal venous gas is a very impressive imaging finding with remarkably diverse etiology and prognostic correspondence. Irrespective of the cause, an approach of managing patients with hepatic portal venous gas according to their clinical condition appears reasonable.

An Unusual Cause of Biliary Peritonitis on the Background of Acute Pancreatitis: A Case Report.

Introduction Acute pancreatitis can cause a wide variety of local complications, sometimes pretty unusual. In the present report, we present a rather unusual cause of biliary peritonitis on the background of acute pancreatitis. Case Presentation A 41-year-old female patient with biliary acute pancreatitis and concomitant choledocholithiasis required an urgent laparotomy due to signs of sepsis and peritoneal irritation after a trial of conservative management. During laparotomy, the diagnosis of biliary peritonitis was established. Surprisingly, a residual gallstone obstructing the common bile duct at the level of the ampulla was causing bile to reflux, through the common channel, into the main pancreatic duct and subsequently into a partially ruptured acute pancreatic necrotic collection. Conclusion Dealing with the unexpected is a constant challenge for the surgical team dealing with acute pancreatitis patients. Although deferring surgical intervention during the course of acute pancreatitis, as much as possible, is the ideal strategy, this is not always possible. Deciding the treatment strategy based on the patients' clinical condition represents the most appropriate approach.

Gastric Cancer Invading the Pancreas: A Review of the Role of Pancreatectomy.

Gastric cancer is quite a common type of cancer, with significant associated mortality. Traditionally, combined resections of affected organs have been advocated in cases of locally advanced gastric cancer, in order to achieve an R0 resection. The purpose of the present study was to evaluate the role of pancreatectomy in the treatment of gastric cancer invading the pancreas by reviewing the relevant literature. The oncological benefits to survival rates of multivisceral resection are not always obvious from the relevant survival charts, especially when the pancreas is the organ invaded by the gastric cancer and gastrectomy needs to be combined with a pancreatectomy, an operation with high morbidity rates. In conclusion, careful patient selection is essential to achieving optimal results, balancing the oncological benefits in these properly selected patients against the associated morbidity of extensive resection.

Extent of Surgical Resection for Gastric Cancer: The Safety Distance Between the Tumor and the Proximal Resection Margin.

A potentially curative treatment scheme for gastric cancer is considered futile without a proper surgical resection. An oncological, surgical resection for gastric cancer prerequisites a proper resection of the stomach, and a D2 lymph node dissection followed by reconstruction of the gastrointestinal tract continuity. Recently, as the favorable impact of organ preserving surgery on functional outcomes has been increasingly appreciated; distal gastrectomy represents a valid alternative to total gastrectomy provided that the proper oncological principles are not violated. However, the appropriateness of distal gastrectomy as a valid type of resection becomes synonymous with achieving a negative proximal resection margin. The purpose of the present study was to assess the optimal distance between the tumor and the resection margin in a gastrectomy with curative intent, performed for gastric cancer, by reviewing the relevant literature. Having in mind, the well documented discrepancy between the gross and the pathologic boundaries of the tumor, pitfalls might be encountered. Current published guidelines have used a "safety distance" i.e., >4 or 5 cm between the proximal macroscopic tumor border and the proximal resection margin in order to guarantee a negative resection margin on pathology. An increased distance of safety is currently proposed in high-risk tumors such as tumors of the diffuse histological type.

Surgical Repair of Iatrogenic Duodenal Injuries with a Roux-en-Y Duodenojejunostomy: A Physiology-oriented Approach.

Introduction: Iatrogenic duodenal injuries represent a condition associated with high morbidity and even mortality. Management is still controversial with a lack of consensus among experts regarding the optimal treatment. The purpose of the present study was to test and assess the results of a certain reconstruction technique. Material and Methods: Four patients (2 males and 2 females) of a mean age of 83 years with iatrogenic duodenal injuries underwent surgical repair of the duodenal perforation, with a two-layer duodenojejunostomy and a Roux-en-Y jejunal loop. Results: Three out of four patients (75%) had a rapid and uncomplicated recovery (13 days mean postoperative length of hospital stay), while the fourth patient died in the ICU due to ARDS three weeks later, without however evidence of anastomotic leak. Conclusion: A variety of surgical repair techniques have been proposed to date; however, with controversial results. A repair using an isolated jejunal Roux-en-Y loop seems to fulfill all the optimal prerequisites for a successful anastomotic outcome and proved efficient in its certain form for the given patient sample.

Surgical versus non-operative initial management of post-endoscopic retrograde cholangiopancreatography perforation: a systematic review and meta-analysis.

BACKGROUND: In the present study we performed a systematic review and meta-analysis regarding the initial management of perforations following endoscopic retrograde cholangiopancreatography (ERCP). METHOD: A systematic review and meta-analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. RESULT: In total, 10 comparative studies and 223 patients with post-ERCP perforations were included in the present study. In type I and II perforations, the success rate of initial surgical management was higher compared to the non-operative management (NOM) group (P=0.09 and P=0.02, respectively). There was no statistically significant difference in mortality rates or length of hospital stay between initial surgical and NOM management for any type of perforation. CONCLUSIONS: The current meta-analysis demonstrated the significance of the initial management of patients with post-ERCP perforations. Whether a surgical or an endoscopic approach is chosen, the patient should immediately be evaluated by an experienced surgeon or endoscopist.

Iatrogenic Bile Duct Injuries: A Critical Appraisal of Classification Systems.

Bile duct injuries represent the most dramatic complications after an open or laparoscopic cholecystectomy. The detrimental effects on patient quality of life and overall survival are the most obvious consequences of such injuries. An effective treatment strategy after accurate mapping of the injury type is the only method of averting these morbid consequences. Several classification systems have been proposed in an attempt to accurately describe and categorize bile duct injuries. The critical question is whether we truly need all these systems and whether each of these systems adds value to the existing knowledge base, or further obscures the field. Each classification system has several advantages to base its clinical utility on, but entails a reasonable number of limitations as well. Currently, a tailored approach adopting the classification system which provides the most appropriate guidance - either in terms of diagnosis or treatment decision making - appears to be the most justified option.

Quality of life deterioration and colorectal cancer staging in elderly patients. Which comes first?

PURPOSE: Never before the preoperative quality of life (QoL) score of colorectal cancer (CRC) patients was analyzed and linked directly to cancer staging according to pathology in specimens and, thereafter, in patients to estimate long-term prognosis. Our study attempted to give answers to these questions. METHODS: This was a prospective study of 80 elderly patients who underwent major colorectal surgery for cancer in a single University's surgical department conducted between 01/2018 and 12/2018. All patients aged >65 years, diagnosed with a resectable CRC without metastatic disease undergoing an elective surgery were prospectively included. As exclusion criteria were considered age <65 years, an emergency operation, non-resectable tumor, stage IV CRC and American Society of Anesthesiologists (ASA) score IV. All patients were asked to answer a self-administered questionnaire of the validated Greek version of the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30. RESULTS: Comparison of the mean score of EORTC QLQ-C30 showed stage I CRC was 87.62% (11.81%), 77.24% (12.91%) in stage II patients and 78.99% (15.25%) in stage III cancer. The mean difference between the three groups was statistically significant (p=0.002). Moreover, in post-hoc analysis, there was a statistically significant difference in the mean QLQ-C30 score between patients with stage I and stage II cancer (p=0.043) and between patients with stage I and stage III tumor (p=0.01), but this difference was not observed when comparing patients with stage II and III cancer (p=0.319). CONCLUSION: Our study demonstrated a significant association between preoperative QoL and tumor staging as shown in the specimen's examination in elderly patients with CRC. More prospective studies are needed to elucidate how QoL and its fluctuations during the postoperative period can be correlated with long-term survival and disease progression in elderly CRC patients.

Differences in surgical oncology practice in Greece and Cyprus between the first and second COVID-19 pandemic waves: Lessons from a paradigm shift.

The SARS-CoV-2 (COVID-19) pandemic has led to the implementation of certain restrictions and rearrangements regarding the surgical oncology operations, thus affecting the surgical lists, the availability of surgical time, along with the consultations of oncologic patients. The purpose of the present study was to identify the differences in surgical oncology practices in Greece and Cyprus between the first and second pandemic waves. We designed a questionnaire for surgeons treating surgical oncology patients. A total of 104 surgeons participated in the present study by answering our questionnaire. According to our outcomes, there was a significant shift between the two waves in patients' willingness to undergo surgery and to present to consultations. Nonetheless, the availability of surgical services remained limited. The consequent mismatch in patients' needs and the availability of healthcare services, we demonstrate herein, is alarming and should be taken into consideration by the policymakers.

Gastrointestinal Stromal Tumor (GIST) and Synchronous Intra-Abdominal Liposarcoma: A Report of Two Rare Cases and Literature Review.

INTRODUCTION: Gastrointestinal stromal tumors (GISTs) quite frequently occur synchronously with other malignancies, with most cases being adenocarcinomas. GISTs and liposarcomas are both of mesenchymal origin, and their coexistence is extremely rare. METHODS: We conducted a review of the current literature regarding the synchronous occurrence of GISTs and intra-abdominal liposarcomas. An electronic search of the literature was undertaken using MEDLINE (database provider PubMed). Furthermore, we present the first described case of an 86-year-old male with a GIST and synchronous liposarcoma, both located in the stomach, as well as a 66-year-old male with a gastric GIST and concurrent retroperitoneal liposarcoma. RESULTS: A total of 5 cases of synchronous GIST and intra-abdominal liposarcoma have been reported in the literature to date, with the most recent cases included in the present study. CONCLUSION: Further research is required to explain any possible correlation in the coexistence of these different neoplasms of the same origin. Meanwhile, R0 resection of both tumors remains the treatment of choice.
