Classification of Hartmann's procedure reversal complications according to the Clavien-Dindo System.

BACKGROUND: Hartmann's Procedure (HP) is performed for cancer, trauma or benign diseases of the left colon. It is regarded as a solution to avoid a risky anastomosis with the intent to reverse after the diseased colon is given time to recover. This reversal has been associated with a potential morbidity and mortality. OBJECTIVES: Our objective was to investigate the complications and morbidities associated with HP reversal. METHODS: The Hartmann reversal operations performed in the general surgery department were reviewed between January 2014 and January 2018 in the Istanbul Haseki Training and Research Hospital. RESULTS: During the evaluation period, 41 patients underwent a HP reversal with the mean age of 57.45 ± 15.75 The majority of the patients were male (73%; n = 30). The overall complication rate was 44%. There were seven (17%) cases of reoperation with high-grade complications, and four (9.8%) of the patients were re-hospitalized due to complications. CONCLUSIONS: HP reversal can be considered a relatively safe operation for a selected group of patients including those with preoperative comorbidities, yielding an anastomotic leakage rate of 7.3% and a hospital readmission rate of less than 10%. The repair of an incisional hernia at the same time does not increase the complication rate. KEY WORDS: Complications, Colostomy, Clavien-Dindo classification, Hartmann's procedure reversal, Hartmann's system procedure reversal.

A grey zone of hyperamylasemia following endoscopic retrograde cholangiopancreatography: follow-up and differential diagnosis from acute pancreatitis.

INTRODUCTION: Endoscopic retrograde cholangiopancreatography (ERCP) is a tool often used for treating and diagnosing pancreaticobiliary diseases. One of the important complications of ERCP is pancreatitis. Even though transient hyperamylasemia is a more common and benign situation, it must be distinguished from post-ERCP pancreatitis. AIM: To define the risk factors associated with post-ERCP pancreatitis (PEP) and tried to identify a cutoff about laboratory findings for positive or negative prediction. MATERIAL AND METHODS: We reviewed the medical files of patients who underwent ERCP for choledocholithiasis in a retrospective cohort study. The primary outcome is the risk factors associated with PEP. Receiver operator characteristics analysis was carried out for determination of cut-offs for laboratory parameters. RESULTS: The presence of cholangitis (p = 0.018), Wirsung cannulation (p = 0.008), presence of abdominal pain at 12th and 24th h (p < 0.001), amylase level at 12th h (p < 0.001), C-reactive protein (CRP) levels at 6th and 12th h (p = 0.001 and p < 0.001), white blood cells (WBC) levels at 6th and 12th h (p = 0.001 and p < 0.001) were significant for development of PEP. CRP levels above 8 mg/l and WBC above 10 × 103 had negative predictive values over 70% and 90% respectively. CONCLUSIONS: Physical examination and inflammatory parameters are important in diagnosis of PEP. CRP and WBC have high negative predictivity and sensitivity. Amylase level increase was most apparent 12 h after ERCP and significantly higher (p < 0.001) for the development of PEP. The first abdominal pain evaluation is meaningful at the 12th h timepoint because insufflation during the procedure and other causes of abdominal pain may result in misinterpretation.

In the Experimental Model of Acute Mesenteric Ischemia, The Correlation of Blood Diagnostic Parameters with the Duration of Ischemia and their Effects on Choice of Treatment.

Purpose/Aim: Acute mesenteric ischemia is a syndrome characterized by sudden onset abdominal pain followed by intestinal necrosis. Morbidity and mortality increase with delayed diagnosis. Even with the latest radiological diagnostic methods, early diagnosis and initiation of treatment can be delayed. Using an experimental model, here we aim to determine the relationship between the laboratory parameters used to detect acute mesenteric ischemia and the duration of irreversible ischemia. Materials and Methods: A total of 30 male Wistar albino rats were divided into five groups, all of which underwent general anesthesia: (i) Superior mesenteric artery (SMA) dissection with laparotomy was performed, and blood samples and intestinal segment samples were taken after 2 hr (Sham group); (ii) volvulus of one-third of the small intestines was performed manually by laparotomy, and blood samples and intestinal segment samples were taken after 2 hr (Volvulus group); (iii) SMA was ligated with laparotomy, and blood samples and intestinal segment samples were taken after 2 hr (SMA+ligated 2-hr group); (iv) SMA was ligated with laparotomy, and blood samples and intestinal segment samples were taken after 4 hr (SMA+ligated 4-hr group); and (v) SMA was ligated with laparotomy, and blood samples and intestinal segment samples were taken after 6 hr (SMA+ligated 6-hr group). Results: The mean lactate dehydrogenase (LDH) activities of the SMA+ligated 2-hr and SMA+ligated 6-hr groups were statistically higher than the control group (p = .004). Compared to the Sham and Volvulus groups, the mean lactate level of the SMA+ligated 6-hr group was significantly higher (p = .004). Compared to the Sham and Volvulus groups, the mean D-dimer levels of the SMA+ligated 4-hr and SMA+ligated 6-hr groups were significantly higher (p = .004 and .003, respectively). By histopathological evaluation, we found that pathological damage increased as the ischemia lengthened. Conclusions: Mesenteric ischemia leads to an irreversible loss of intestinal perfusion and an increase in parameters of ischemia. Irreversible tissue damage occurs after 4 hr of ischemia and peaks after 6 hr, whereas parameters of ischemia (D-dimer, LDH, and L-Lactate levels) are highest at 2 hr after the onset of ischemia.

Open mesh and laparoscopic total extraperitoneal inguinal hernia repair under spinal and general anesthesia.

INTRODUCTION: Mesh placement is the main standard in repair of inguinal hernia, and laparoscopic repair is the standard of care via spinal, epidural, or combined anesthesia. Here, we compared open and laparoscopic total extraperitoneal (TEP) repairs under general (GA) and spinal anesthesia (SA). METHODS: Inguinal hernia patients (n=440) were analyzed retrospectively. There were four groups: Group 1 was TEP under GA (TEP-GA) (n=111); Group 2 was open mesh repair (OM) under SA (n=116) (OM-SA); Group 3 was open mesh repair under GA (n=117) (OM-GA); Group four was TEP under SA (n=96) (TEP-SA). The age, body mass index, duration of operation, hospital stay, postoperative Visual Analog Scale scores, recurrence, postoperative pain, urinary retention, headache, and patient satisfaction were all recorded. RESULTS: There was no significant difference in terms of hypotension, vomiting, seroma and scrotal edema, recurrence, and wound infection incidence between the groups. However, the operation duration, hospital stay period, headache, urinary retention, postoperative Visual Analog Scale scores, chronic pain, and patient satisfaction showed significant differences between groups. CONCLUSION: Laparoscopic TEP hernia repair is a safe and effective method along with its advantages of shorter hospital stay, less recurrence, less postoperative pain, higher patient satisfaction, and similar postoperative complication rates. SA has the disadvantage of higher incidence of headache and urinary retention compared to GA.

Post-cesarean scar endometriosis.

OBJECTIVE: Endometriosis is seen in women during their reproductive period, where stromal tissue and functional endometrial glands of the uterus are observed outside the uterine cavity. In this study, we aimed to identify the clinical characteristics of our patients who underwent surgery with scar endometriosis and to discuss the surgical results in light of the literature. MATERIALS AND METHODS: A total of 24 patients who underwent surgery and diagnosed as having endometriosis as the result of a pathologic examination were retrospectively evaluated. RESULTS: The mean age of the patients was 31 years. Thirteen presented to general surgery and 11 presented to gynecology outpatient clinics. The pain was cyclical in 19 patients. There was history of cesarean section in 9 patients, twice in 12, and 3 times in three patients. The mean diameter was 39.1 mm on ultrasound, and 37.5 mm on magnetic resonance imaging. Endometriosis was on the left side of the incisions in 13, whereas it was on the right in 11. The mean weight of the lesions was 61.6 grams. CONCLUSION: The occurrence of endometriosis is supported by the iatrogenic implantation theory. In the event of a mass in the abdominal wall, previous obstetric and gynecologic operations and a history of a painful mass during menstruation periods must be questioned. In the treatment of scar endometriosis, excision is required by obtaining secure margins. If diagnosis can be established preoperatively, unnecessary surgeries can prevented.

The Effect of Sterilization Methods of Endoscopic Instruments on the Body: A Study on Rat Model.

PURPOSE: Laparoscopy is widely used in many surgical areas for diagnosis and treatment. The need for sterilization of reusable instruments is an important issue. Ensuring patient safety, preventing infection, and protecting the functionality of the instruments are the most important points to be considered. We aimed to investigate two sterilization methods and their effects generated by their distribution into intra-abdominal tissues during insufflation. MATERIALS AND METHODS: 21 rats were used in the study. The Control Group (Group 1) received anesthesia for 1 hour; Group 2 (Glutaraldehyde (GA)-Pneumoperitoneum Group) received anesthesia for 1 hour; Group 3 (Ethylene Oxide (EO)-Pneumoperitoneum Group) received anesthesia for 1 hour. After 24 hours, the animals were sacrificed, and the kidneys and omentum of the animals were analyzed in a histopathological manner. Blood samples were analyzed at preoperative 24th hour and at postoperative 24th hour. RESULTS: There was a statistically significant difference in omentum, endothelium, and glomerular scores between the groups (p < 0.001 for all groups). Endothelial and glomerular scores were different at a statistically significant level in the EO and GA groups compared to the Control Group. The total score was higher at a statistically significant level in the EO and GA groups compared to the Control Group (p < 0.001 for both groups). CONCLUSION: It was determined in our study that sterilization methods such as EO and GA cause damage in intra-abdominal tissues. In the light of these results, we consider that the most ideal laparoscopic surgery set is the single-use laparoscopy set. However, this does not seem possible especially in developing countries in practice.

Is it possible to reduce the surgical mortality and morbidity of peptic ulcer perforations?

OBJECTIVE: Peptic ulcer perforation is a life-threatening situation requiring urgent surgical treatment. A novel vision in peptic ulcer perforation is necessary to fill the gaps created by antiulcer medication, aging of the patients, and presentation of resistant cases in our era. In this study, we aimed to share our findings regarding the effects of various risk factors and operative techniques on the mortality and morbidity of patients with peptic ulcer perforation. MATERIAL AND METHODS: Data from 112 patients presenting at our Training and Research Hospital Emergency Surgery Department between January 2010 and December 2015 who were diagnosed with PUP through physical examination and laboratory and radiological tests and operated at the hospital have been retrospectively analyzed. Patients were divided into three groups based on morbidity (Group 1), mortality (Group 2), and no complication (Group 3). RESULTS: Of the 112 patients included in the study, morbidity was observed in 21 (18.8%), mortality in 11 (9.8%), and no complication was observed in 80 (71.4%), who were discharged with cure. The differences between group for the average values of the perforation diameter and American Society of Anesthesiologists, Acute Physiology and Chronic Health Evaluation II, and Mannheim Peritonitis Index scores were statistically significant (p<0.001 for each). The average values for the group with mortality were significantly higher than those of the other groups. CONCLUSION: In this study where we investigated risk factors for increased morbidity and mortality in PUPs, there was statistically significant difference between the average values for age, body mass index, perforation diameter, and Acute Physiology and Chronic Health Evaluation II and Mannheim Peritonitis Index scores among the three groups, whereas the amount of subdiaphragmatic free air did not differ.

The effects of prolonged CO2 insufflation on kidney function in a rat pneumoperitoneum model.

INTRODUCTION: Pneumoperitoneum (PP) is known to cause ischemia in kidneys and other intra-abdominal organs because of decreased splanchnic blood flow. AIM: We aimed to determine the degree of renal injury that occurs due to a PP and prolonged PP. We measured renal injury biomarkers and made a histopathological evaluation to estimate the degree of injury and assessed the correlation of biomarkers with histopathological findings. MATERIAL AND METHODS: Twenty-one female Sprague Dawley rats were separated randomly into three groups. Group 1 was the control group and was given anesthesia for 3 h. In group 2, a PP was administered under anesthesia for 1 h. A pneumoperitoneum was administered under anesthesia to animals in group 3 for 3 h. RESULTS: Pathological analysis showed a significant statistical difference between the 3 groups. In particular, neutrophil gelatinase-associated lipocalin (NGAL) and cystatin C (Cys C) levels at the 24th h and preoperative mean urea levels showed a significant difference between the groups. The 24th-hour NGAL level in group 3 was significantly higher than that of group 1. The preoperative Cys C level was higher in group 1 than in either group 2 or 3. Cys C was decreased significantly in group 1 and increased significantly in both groups 2 and 3. CONCLUSIONS: The increase in NGAL and Cys C levels directly correlated with the duration of PP and intra-abdominal pressure, and they are therefore good biomarkers in diagnosing acute renal injury in the early phase. Serum creatinine level is not a good biomarker in the early phase of renal injury.

Prognostic factors in patients with acute mesenteric ischemia.

OBJECTIVE: Acute mesenteric ischemia, one of the causes of acute abdominal pain due to occlusion of the superior mesenteric artery, has a fatal course as a result of intestinal necrosis. There is no specific laboratory test to diagnose acute mesenteric ischemia. The basis of treatment in cases of acute mesenteric ischemia is composed of early diagnosis, resection of intestinal sections with infarction, regulation of intestinal blood flow, second look laparotomy when required, and intensive care support. The aim of this study is to investigate the factors affecting mortality in patients treated and followed-up with a diagnosis of acute mesenteric ischemia. MATERIAL AND METHODS: Forty-six patients treated and followed-up with a diagnosis of acute mesenteric ischemia between January 1st, 2008 and December 31st, 2014 at the General Surgery Clinic of our hospitalwere retrospectively evaluated. The patients were grouped as survivor (Group 1) and dead (Group 2). Age, gender, accompanying disorders, clinical, laboratory and radiologic findings, duration until laparotomy, evaluation according to the Mannheim Peritonitis Index postoperative complications, surgical treatment applied, and type of ischemia and outcome following surgery were recorded. RESULTS: A total of 46 patients composed of 22 males and 24 females with a mean age of 67.5±17.9 and with a diagnosis of mesenteric ischemia were included in the study. Twenty-seven patients died (58.7%) while 19 survived (41.3%). The mean MPI score was 16.8±4.7 and 25.0±6 in Group 1 and Group 2, respectively, and the difference between the two groups was statistically significant (p<0,001). Fourteen of the 16 (51.9%) patients who had a Mannheim Peritonitis Index score of 26 or higher died while two of them survived (10.5%). Thirteen out of the 30 (48.1%) patients with a Mannheim Peritonitis Index score of 25 or lower died while 17 (89.5%) patients survived. The increased MPI score was significantly correlated withmortality (p=0.004). CONCLUSION: Suspicion of disease and early use of imaging in addition to clinical and laboratory evaluations are essential in order to decrease mortality rates in acute mesenteric ischemia. Prevention of complications with critical intensive care during the postoperative period aids in decreasingthe mortality rate. In addition, using the Mannheim Peritonitis Index can be helpful.

Combined spinal-epidural anesthesia in laparoscopic appendectomy: a prospective feasibility study.

PURPOSE: Laparoscopic appendectomy (LA) is routinely performed under general, not regional anesthesia. This study assessed the feasibility, efficacy, and side effects of combined spinal-epidural anesthesia (CSEA) in LA. METHODS: Thirty-three American Society of Anesthesiologist (ASA) physical status classification grade I patients underwent LA under CSEA. CSEA was performed using the needle-through-needle technique at the L3-L4 interspace. Preoperative and postoperative adverse events related to CSEA, patient satisfaction, and postoperative pain levels were recorded. RESULTS: LA under CSEA was performed successfully in 33 patients (84.6%). Peroperatively, right shoulder pain was observed in 8 patients (24.1%), abdominal discomfort in 6 (18.2%), anxiety in 5 (15.2%), hypotension in 2 (6.1%) and nausea-vomiting in 1 (3%). In the first 24 hours after LA, headache, urinary retention, right shoulder pain, and postoperative nausea/vomiting (PONV) occurred in 18.1%, 12.1%, 9.1%, and 0% of patients, respectively. In the first 6 hours postoperation, no patients had operation-site pain that required analgesic treatment. Thirty-one patients (94%) evaluated their satisfaction with the procedure as good or moderate. CONCLUSION: CSEA is an efficient and suitable anesthesia technique in LA for ASA physical status classification grade I healthy patients. CSEA is associated with good postoperative pain control and the absence of PONV and intubation-associated complications.

Spinal anesthesia is safe in laparoscopic total extraperitoneal inguinal hernia repair. A retrospective clinical trial.

INTRODUCTION: Laparoscopic total extraperitoneal (TEP) inguinal hernia repair is an effective and safe method for the treatment of inguinal hernia. There are very few studies on regional anesthesia methods in TEP surgery. AIM: To compare TEP inguinal hernia repair performed when the patient was treated under spinal anesthesia (SA) with that performed under general anesthesia (GA). MATERIAL AND METHODS: All total of 80 patients were studied between December 2015 and March 2017. Hyperbaric bupivacaine and fentanyl were used for SA, to achieve a sensorial level of T3. Propofol, sevoflurane, rocuronium, fentanyl, and tracheal intubation were used for GA. Intraoperative events related to SA, surgical times, intra- and postoperative complications, and pain scores were recorded. RESULTS: The mean operative time in the SA TEP group was 70.2 ±6.7 min, which was significantly longer than the mean operative time in the GA TEP group of 67.2 ±6.2 min (p < 0.038). The mean pain scores in the SA TEP group were 0.23 ±0.42 at the first hour, 1.83 ±0.64 at 6 h and 1.28 ±0.45 at 24 h. These scores were significantly lower than the corresponding scores of 5.18 ±0.84 (p < 0.001), 2.50 ±0.55 (p < 0.001) and 1.58 ±0.55 in the GA TEP group. Generally, patients were more satisfied with SA than GA (p < 0.004). CONCLUSIONS: Spinal anesthesia TEP is significantly less painful in the early postoperative period, leading to earlier ambulation than GA TEP. Additionally, SA TEP results in significantly less need for analgesics and better patient satisfaction results. SA TEP seems to be a better alternative than the existing GA TEP.

A comparison of propofol and midazolam/meperidine sedation in upper gastrointestinal endoscopy.

INTRODUCTION: There is increasing interest in sedation for upper gastrointestinal endoscopy (UGE). Prospective randomized studies comparing sedation properties and complications of propofol and midazolam/meperidine in upper gastrointestinal endoscopy (UGE) are few. AIM: To compare propofol and midazolam/meperidine sedation for UGE in terms of cardiopulmonary side effects, patient and endoscopist satisfaction and procedure-related times. MATERIAL AND METHODS: This was a prospective, randomized, double-blind study of propofol versus midazolam and meperidine in 100 patients scheduled for diagnostic upper gastrointestinal endoscopy. The patients were divided into propofol and midazolam/meperidine groups. Randomization was generated by a computer. Cardiopulmonary side effects (hypotension, bradycardia, hypoxemia), procedure-related times (endoscopy time, awake time, time to hospital discharge), and patient and endoscopist satisfaction were compared between groups. RESULTS: There was no significant difference between the groups with respect to the cost, endoscopy time, or demographic and clinical characteristics of the patients. Awake time and time to hospital discharge were significantly shorter in the propofol group (6.58 ±4.72 vs. 9.32 ±4.26 min, p = 0.030 and 27.60 ±7.88 vs. 32.00 ±10.54 min, p = 0.019). Hypotension incidence was significantly higher in the propofol group (12% vs. 0%, p = 0.027). The patient and endoscopist satisfaction was better with propofol. CONCLUSIONS: Propofol may be preferred to midazolam/meperidine sedation, with a shorter awake and hospital discharge time and better patient and endoscopist satisfaction. However, hypotension risk should be considered with propofol, and careful evaluation is needed, particularly in cardiopulmonary disorders.

Is there any effect of pneumoperitoneum pressure on coagulation and fibrinolysis during laparoscopic cholecystectomy?

BACKGROUND: Laparoscopic cholecystectomies (LC) are generally performed in a 12 mmHg-pressured pneumoperitoneum in a slight sitting position. Considerable thromboembolism risk arises in this operation due to pneumoperitoneum, operation position and risk factors of patients. We aim to investigate the effect of pneumoperitoneum pressure on coagulation and fibrinolysis under general anesthesia. MATERIAL AND METHODS: Fifty American Society of Anesthesiologist (ASA) I-III patients who underwent elective LC without thromboprophlaxis were enrolled in this prospective study. The patients were randomly divided into two groups according to the pneumoperitoneum pressure during LC: the 10 mmHg group (n = 25) and the 14 mmHg group. Prothrombin time (PT), thrombin time (TT), International Normalized Ratio (INR), activated partial thromboplastin time (aPTT) and blood levels of d-dimer and fibrinogen were measured preoperatively (pre), one hour (post1) and 24 h (post24) after the surgery. Moreover, alanine amino transferase, aspartate amino transferase and lactate dehydrogenase were measured before and after the surgery. These parameters were compared between and within the groups. RESULTS: PT, TT, aPTT, INR, and D-dimer and fibrinogen levels significantly increased after the surgery in both of the groups. D-dimer level was significantly higher in 14-mmHg group at post24. CONCLUSION: Both the 10-mmHg and 14-mmHg pressure of pneumoperitoneum may lead to affect coagulation tests and fibrinogen and D-dimer levels without any occurrence of deep vein thrombosis, but 14-mmHg pressure of pneumoperitoneum has a greater effect on D-dimer. However, lower pneumoperitoneum pressure may be useful for the prevention of deep vein thrombosis.

Two-port laparoscopic appendectomy assisted with needle grasper comparison with conventional laparoscopic appendectomy.

PURPOSE: The 2-port laparoscopic appendectomy technique (TLA) is between the conventional 3-port and single-port laparoscopic appendectomy surgeries. We compared postoperative pain and cosmetic results after TLA with conventional laparoscopic appendectomy (CLA) by a 3-port device. METHODS: Patients undergoing TLA were matched with patients undergoing CLA between February 2015 and November 2015 at the same institution. Thirty-two patients underwent TLA with a needle grasper. The appendix was secured by a percutaneous organ-holding device (needle grasper), then removed through a puncture at McBurney's point. Another 38 patients underwent CLA. Patient demographics, operative details, and postoperative outcomes were collected and evaluated. RESULTS: One patient in the TLA group developed a wound infection and 1 patient in the CLA group developed a postoperative intra-abdominal abscess and 3 wound infections. There was no significant difference between the groups when comparing the length of hospital stay, time until oral intake, and other complications. The pain score in the first 12 hours after surgery was significanly higher in CLA group than the TLA group (P < 0.001). Operative time was significantly shorter in the CLA group compared to the TLA group (P < 0.001). CONCLUSION: TLA using a needle grasper was associated with a significantly lower pain score 12 hours after surgery, better cosmetic results, and lower cost, than the CLA 3-port procedure because of the fewer number of ports.

Two-port laparoscopic appendectomy with the help of a needle grasper: better cosmetic results and fewer trocars than conventional laparoscopic appendectomy.

INTRODUCTION: The two-port laparoscopic appendectomy technique (TPLA) lays between the conventional three-port trocar procedure and single-port laparoscopic appendectomy surgery. During TPLA, the appendix is suspended with stitches, resulting in perforation risk and difficulty in exploration. AIM: We used a needle grasper in TPLA to hang and manipulate the appendix. MATERIAL AND METHODS: Thirty-four patients (10 female, 24 male) who underwent TPLA between February 2015 and November 2015 were analyzed retrospectively for patient demographics, duration of operation, laparotomy or conventional laparoscopy necessity, drain use, complications, and hospital stay periods. The needle grasper was inserted at the right under the abdominal quadrant (McBurney point) without an incision to hang and manipulate the appendix. RESULTS: The mean age was 25.19 ±8.464 years; the mean body mass index (BMI) was 23.50 ±3.246 kg/m(2). ASA scores were 1 and 2. The operations were completed without any additional trocar in 34 patients. The mean operation time was 57.03 ±3.814 min. There were no intraoperative complications in any patients. Three patients required a drain; all were discharged after drain removal. Thirty-one patients were discharged on the 1(st) postoperative day; three patients with drains were discharged on the 2(nd) day. The mean hospital stay period was 1.18 ±0.535 days. CONCLUSIONS: Using the needle grasper, the appendix was held and suspended and the mesoappendix was cauterized and skeletonized successfully in TPLA. Inserting a needle grasper into the abdominal cavity at the McBurney point to manipulate the appendix helps and does not leave a visible scar.

Gastrointestinal Stromal Tumors with Unusual Localization: Report of Three Cases with a Brief Literature Review.

The most common tumors derived from the mesenchyme of the gastrointestinal system are stromal tumors. These tumors are typically seen in the stomach and small intestine and less frequently in the colon, rectum and esophagus and are very rarely located outside the gastrointestinal system. Cure is provided with complete surgical resection with resection borders free of tumor. Tumor size, mitotic index, localization, CD117 and CD34 negativity in immunohistochemical studies, mucosal ulceration and presence of necrosis help to predict recurrence of the illness and patient survival. In high-risk gastrointestinal stromal tumors (GISTs) there is an increased rate of recurrence and shortened survival despite complete surgical resection. Thus patients with a high-risk GIST should be given adjuvant therapy with imatinib mesylate. Sunitinib maleate is another FDA-approved agent only for cases who cannot tolerate imatinib or who are resistant to it. Herein we present three cases with GISTs in different locations of the gastrointestinal system with a review of the relevant literature.
