Incidental detection of gastrointestinal stromal tumors during laparoscopic sleeve gastrectomy. What to do?

INTRODUCTION: We evaluated and characterized the incidental GISTs during laparoscopic sleeve gastrectomy in our clinic. METHODS: All GISTs identified during laparoscopic sleeve gastrectomy between January 2015 and December 2017 were evaluated. Typical demographic, clinicopathologic, treatment, location, resection margins, immunohistochemistry (CD 34, CD 117, ASMA, desmin and S100) and criteria for oncological aggressiveness (tumor size, number of mitoses, presence or absence of tumor necrosis) data were recorded. RESULTS: Within the 800 bariatric surgeries at our institution, 7 GISTs were identified (0.87%). The median age of the patients was 32 years (age range: 24-42 years). The mean BMI was found to be 40.66 kg/m2 (range: 35-44 kg/m2). All GIST cases were found in the stomach samples. All tumors were not larger than 20 mm. All tumors were found close to the greater curvature of the stomach; in five cases, tumors were located in a single focus, while in 1 case, it was located both in the corpus and fundus. CD117 and CD34 were found to be positive in the pathological examination of all parts. In addition, desmin, smooth muscle actin (SMA) and S-100 were also positively stained. No complications or mortality were observed in this series. CONCLUSION: Tumor resection with a negative surgical margin may be considered complete oncologic treatment in case of presence of very low or low risk classification of postoperative GIST recurrence. After GIST resection, all patients should remain under long-term postoperative care. KEY WORDS: Bariatric surgery, Incidental gastrointestinal stromal tumors, Obesity, Sleeve gastrectomy.

A complication of thyroidectomy: Do not forget suture reaction.

OBJECTIVE: In this study, we aimed to present patients who have developed suture reaction and were treated in our clinic following thyroidectomy operation. MATERIAL AND METHODS: Patients who had been treated for suture reaction following thyroidectomy between January 2012 and December 2014 were retrospectively evaluated. The patients were analyzed in terms of their age, gender, duration of the symptoms, type of previous operation and treatment modality. RESULTS: Between January 2012 and December 2014, 559 thyroid/parathyroid operations were performed in our clinic. A total of 12 patients were admitted with suture reaction within this period thus yielding a suture reaction incidence of 2.1%. The mean age of these patients was 42±7.65 years, 75% of them were female while 25% of them were male. The types of previous operations were bilateral total thyroidectomy in 83.3%, lobectomy in 8.3% and near total thyroidectomy in 8.3% of the patients. The mean symptom duration was 7.2±4.3 (2-16) months. Two patients (16.7%) underwent a second surgical operation for suture reaction, while 10 patients (83.3%) were treated conservatively. None of the patients developed complications. CONCLUSION: One of the most common complications that develop after thyroidectomy is bleeding. Ligation must be performed in order to prevent this complication. As it is known, surgical ligation with sutures may cause tissue reaction. Sutures that are absorbable and have a low risk for reaction formation should be chosen if suturing is preferred.

Effects of Mastalgia in Young Women on Quality of Life, Depression, and Anxiety Levels.

The aims of this study are to evaluate whether or not there is a relationship between mastalgia with anxiety and depression in young women with mastalgia who do not have organic breast pathology and to examine the effect of pain on the quality of life. Forty female pre-menopausal patients between the ages of 20-40 years with mastalgia and 40 totally healthy volunteers with the same characteristics were investigated with the Short Form 36 (SF-36), Hamilton Depression Scale, and the Hamilton Anxiety Rating Scale prospectively following breast examination and radiological examination. Statistical assessments were performed using the SPSS 11.5. Anxiety levels were observed to be higher in the patient group (p = 0.04). The depression level was higher in the patient group; however, this was not statistically significant (p = 0.08). The quality of life of the mastalgia group was determined to be lower than that of the control group, and the sub-parameters of physical function (p = 0.04), body pain (p = 0.02), general health (p = 0.03), and energy (p = 0.008) were found to be significantly low. There may be a relationship between mastalgia and depression in young women with mastalgia; however, a closer relationship between anxiety and mastalgia is observed. Mastalgia affects the quality of life of an individual negatively at a significant degree.

Comparing sutures and human fibrin glue for mesh fixation during open inguinal hernioplasty.

PURPOSE: The aim of this study is to evaluate pain and further disabling complications in patients undergoing Lichtenstein technique for primary inguinal hernia repair by fixing the mesh with fibrin sealant versus sutures. METHODS: This study was carried out on 116 patients between January 2009 and July 2009. All patients were male, between the ages of 20 and 75 years. Lichtenstein, using a polypropylene mesh as prosthetic material. A total of 116 hernias were operated on. Group I: 54 operations were done using the conventional repair procedure with polypropylene sutures (prolene 2/0) for mesh fixation. Group II: 62 operations were done using fibrin glue for fixation of the mesh. All patients were operated as day cases, with a maximum hospital stay of 12 hours; none required readmission. RESULTS: No complications were observed in follow-up at 1 week, 1 month, 6 months and 12 months. At 12 months, none of the patients had developed a recurrence. The mean time for complete healing of wound after herniorrhaphy plus fibrin sealant was 8.13±7.88 days (range 6-28 days). This was markedly increased in group 1 patients (mean 12.08±8.59days, and range 8-32) (p <0.001).12 months after surgery, The median VAS pain score was significantly lower in group 2 patients (P < 0·001). The mean (SD) duration of incapacity for work was 5 (2-12) days in group 2(p <0.001). CONCLUSIONS: This study confirms the effectiveness of fibrin glue in securing prosthetic meshes and reducing chronic inguinal pain. KEY WORDS: Chronic pain, Fibrin glue, Inguinal hernia repair.

An obstruction not to forget: Pseudo-obstruction (Ogilvie syndrome): Single center experience.

PURPOSE: Colonic pseudo obstruction disease commonly seen in the elderly, immobile patient group can cause serious mortality and morbidity. Our objective in this retrospective study is to share our clinical experience by evaluating patients with Ogilvie syndrome who were followed and treated in our clinic. METHODS: Eleven cases with the diagnosis of Ogilvie syndrome followed up and treated between September 2010 and April 2013 were evaluated retrospectively. All the patients that had no symptoms of acute abdominal pain were initiated conservative treatment. Colonoscopic decompression was attempted for patients whose clinical pictures were not recovered. Patients underwent operation if they developed peritoneal irritation symptoms during these procedures and of their number of white blood cells seriously increased during the follow-up period. RESULTS: A total of 11 patients were treated for Ogilvie syndrome. 6 of the patients underwent surgical treatment, and 5 were treated medically. Mortality developed in two patients. The main cause of mortality was a delay in diagnosis and additional severe underlying diseases. Seven patients were given Neostigmine. Of these, 2 patients required surgery and 3 patients responded to Neostigmine. CONCLUSION: Ogilvie syndrome is a rare cause of ileus of the colon. It is more common particularly in old patients with additional problems. If the disease is suspected and diagnosed early, unnecessary surgical interventions can be prevented with medical treatment choices.

Does hyperbaric oxygen therapy reduce the effects of ischemia on colonic anastomosis in laparoscopic colon resection?

BACKGROUND: An increase in intra-abdominal pressure causes a decrease in the splanchnic blood flow and the intramucosal pH of the bowel, as well as increasing the risk of ischemia in the colon. The aim of the present study is to evaluate the effect of hyperbaric oxygen therapy (HBOT) on the ischemia caused by laparoscopy in colonic anastomosis in an experimental model of laparoscopic colonic surgery. MATERIALS AND METHODS: We divided 30 male Wistar albino rats into three groups: Group A was the control (open colon anastomosis); Group B received LCA (laparoscopic colon anastomosis); while Group C received both LCA and HBOT. Each group contained ten animals. We placed Group C (LCA and HBOT) in an experimental hyperbaric chamber into which we administered pure oxygen at 2.1 atmospheres absolute 100% oxygen for 60 min for ten consecutive days. RESULTS: The anastomotic bursting pressure value was found to be higher in the open surgery group (226 ± 8.8) (Group A). The result for Group C (213 ± 27), which received HBOT, was better than that for Group B (197 ± 27). However, there was no statistically significant difference between Group B and Group C. Group A showed better healing than the other groups, while significant differences in the fibroblast proliferation scores were found between Groups A and B. In terms of tissue hydroxyproline levels, a significant difference was found between Groups A and B and between Groups A and C, but not between Groups B and C. CONCLUSIONS: HBOT increases the oxygen level in the injured tissue. Although HBOT might offer several advantages, it had only a limited effect on the healing of colonic anastomosis in rats with increased intra-abdominal pressure in our study.

The effects of melatonin on liver functions in arsenic-induced liver damage.

OBJECTIVE: Arsenic exposure is increasing in communities due to environmental pollution and industrial development. Arsenic is toxic to organ systems because it causes oxidative stress, enzymatic inhibition, and damage to protein structures. The liver, for example, is an organ that may be damaged by arsenic, and this damage may cause various clinical conditions like hepatic failure or cancer. Melatonin is a hormone that acts like an antioxidant, an anti-inflammatory agent, and a cytoprotective agent. In this study, we aimed to evaluate melatonin's protective effects on livers damaged by arsenic toxicity. MATERIALS AND METHODS: Twenty-four Sprague-Dawley male rats were classified into three groups: a control group, an arsenic applied group, and an arsenic plus 10 mg/kg melatonin applied group. At the end of the fifteen-day experiment, the rats were sacrificed. Albumin, interleukin-6 (IL-6), total protein, alanine transaminase, aspartate transaminase, macrophage migration inhibitory factor, and monocyte chemotactic protein-1 measurements were obtained. RESULTS: In rats with liver damage due to arsenic exposure, melatonin administration significantly decreased the levels of IL-6, macrophage migration inhibitory factor, and monocyte chemotactic protein-1 (p<0.001, p=0.02 and p=0.04, respectively). CONCLUSION: After evaluating liver enzymes and inflammatory markers, this study determined that melatonin exposure improves liver tissue damage caused by arsenic exposure, with the degree of improvement varying based on the levels of arsenic exposure.

Effectiveness of Limberg and Karydakis flap in recurrent pilonidal sinus disease.

OBJECTIVE: Sacrococcygeal pilonidal sinus is common in young men and may recur over time after surgery. We investigated whether a factor exists that can aid in the determination of the preferred technique between the early Limberg flap and Karydakis flap techniques for treating recurrent pilonidal sinus. MATERIALS AND METHODS: This prospective and randomized study enrolled 71 patients with recurrent pilonidal sinus in whom the Limberg flap or Karydakis flap techniques were applied for reconstruction after excision. Patients were divided into two groups as follows: 37 patients were treated with the Limberg flap technique and 34 patients were treated with the Karydakis flap technique. Fluid collection, wound infection, flap edema, hematoma, partial wound separation, return to daily activities, pain score, complete healing time, painless seating and patient satisfaction were compared between the groups. ClinicalTrial.gov: NCT02287935. RESULTS: The development rates of total fluid collection, wound infection, flap edema, hematoma, and partial wound separation were 9.8%, 16%, 7%, 15% and 4.2%, respectively; total flap necrosis was not observed in any patient (p<0.001). During the average follow-up of 28 months, no patients (0%) developed recurrent disease. The two groups differed with respect to early surgical complications (p<0.001). CONCLUSION: In this study, use of the Limberg flap was associated with lower complication rates, shorter length of hospital stay, early return to work, low pain score, high patient satisfaction and better complete healing duration. Therefore, we recommend the Limberg flap for treatment of recurrent pilonidal sinus.

Comparison of intracorporeal knotting and endoloop for stump closure in laparoscopic appendectomy.

BACKGROUND: Several appendiceal stump closure tecniques such as intracorporoeal-knotting, endoloop, stapler and clips are used during laparoscopic appendectomy. This study aimed to compare intracorporoeal-knotting and endoloop tecniques used to close appendiceal stump in laparoscopic appendectomy. METHODS: This study included patients who underwent laparoscopic appendectomy with preliminary diagnosis of acute appendicitis in General Surgery Department of Adana Numune Training and Research Hospital between June 2009 and July 2013. The demographics, appendiceal stump closure tecniques, operation time, complications, and length of hospital stays of the patients were compared. RESULTS: A total of one hundred and twenty-six patients underwent laparoscopic appendectomy (Female: 81, Male: 45). Intracorporeal-knotting (Group 1) was performed in sixty-five patients; whereas, endoloop (Group 2) was performed in sixty-one patients in order to close appendiceal stump. The operation time was longer in Group 1 compared to Group 2 (62.0±10.67 min., 56.80±11.94 min., p=0.01). The length of hospital stays were nonsignificant between the groups. Four patients were complicated by superficial surgical site infection in both groups. CONCLUSION: In the present study, the operation time was found to be longer for intracorporeal knotting tecnique compared to endoloop tecnique; however, there was no significant difference regarding the length of hospital stay and complications. Performing intracorporeal-knotting technique is suggested since it is cheaper than endoloops and it may also improve hand manipulations of the surgeons who intend to advanced laparoscopy.

Comparison of early surgery (unroofing-curettage) and elective surgery (Karydakis flap technique) in pilonidal sinus abscess cases.

BACKGROUND: The aim of this study is to compare the effectiveness and success of early (acute) period local surgical intervention (unroofing-curettage) followed by dressing and secondary healing with the surgery performed in elective conditions (pilonidal sinus excision and Karydakis flap) following conventional abscess treatment (drainage-antibiotic therapy) in pilonidal sinus abscess cases. METHODS: The data of the patients treated for pilonidal sinus abscesses in our clinic between January 2012 and March 2013 were analyzed, retrospectively. Those who had early surgery were determined as Group S, and those who had elective surgery following drainage-antibiotic therapy were determined as Group K. Patients in both groups were compared in terms of age, gender, complications, recurrence rate and healing time. Patients were followed for an average of 14 months. RESULTS: Of the 53 patients included in the study, 28 were in Group S and 25 in Group K. The mean age and gender distribution of both groups were similar and a significant difference was not found between the groups in terms of complication development and recurrence. However, there was a statistically significant difference between the groups in terms of treatment duration (p=0.02). CONCLUSION: In treating acute pilonidal abscesses, the Karydakis method, following drainage-antibiotic therapy, is a preferable method due to its shorter treatment duration and higher patient comfort.

Outcome analysis of laporoscopic D1 and D2 dissection in patients 70 years and older with gastric cancer.

OBJECTIVE: Gastric cancer is a worldwide aggressive tumor with a bad prognosis. The purpose of this study was to retrospectively investigate operative findings of 53 patients aged over 70 with gastric cancer who underwent laporoscopic operations in our clinic. MATERIAL AND METHODS: A retrospective review of all patients who underwent laporoscopic surgery for pathologically confirmed gastric cancer at our clinic between March 2008 and October 2010 was conducted. D1 resection (Level1 lymphadenectomy) was compared with D2 resection (Levels 1 and 2 lymphadenectomy). The two groups in which D1 and D2 Lymph node Dissection (LND) were applied were compared with respect to number of patients, sex, age, stage of disease, and score of American Society of Anesthesiologists (ASA). We analyzed surgical methods, the use of staplers, operative time, additional organ resections, hospital stay, postoperative complications and the need for re-operation, operative mortality, and the effects of prognostic factors on survival. RESULTS: The patient group consisted of 31 (58%) males and 22 (42%) females. Of the patients, 28 (52%) underwent D1 and 25 (48%) D2 LND. There was a significant difference between the two groups with regard to length of surgery (p < 0.01). The length of operation, blood loss, and transfusion requirement in the D2 group were significantly more than those in the D1 group. There was no mortality in cases that underwent additional organ resection. The survival times of cases with a ≤ 0.25 ratio of dissected number of lymph nodes to metastatic lymph nodes were significantly longer than those of other cases. The survival time of cases with perineural and vascular invasion was significantly shorter. The survival rates of Stage I patients was significantly higher than those of Stage III (p:0.002) and Stage IV (p:0.003) patients. CONCLUSIONS: Although extensive dissection had an increased morbidity, there was no significant statistical difference between the two procedures. Early complications should not be attributed only to the extent of LND. The important prognostic factors related to long-time survival are the stage of the tumor, perineural and perivascular invasion, and metastatic lymph nodes.

Sinotomy technique versus surgical excision with primary closure technique in pilonidal sinus disease.

Pilonidal disease is a common chronic disorder mainly seen in the sacrococcygeal region, especially in young males. Many surgical treatment modalities have been suggested, but an ideal and widely accepted treatment has yet to be established. The aim of this study was to compare quality of life of patients treated with the sinotomy technique with quality of life of patients treated with surgical excision plus primary closure technique by means of quality of life questionnaire. The data of patients who had been treated for pilonidal sinus in our clinic from September 2010 to June 2012 were analyzed retrospectively. Forty patients were treated with sinotomy technique and 40 patients were treated with surgical excision plus primary closure technique. Time to return to work and to time to complete wound healing were evaluated. All patients were asked to fill the questionnaire after complete healing occurred. Postoperative complications were bleeding in 2.5%, infection in 3.75% and fever in 2.5% patients. There were no significant differences between the two groups in terms of complete healing (p=0.1) and sport times (p=0.1). There were significant differences between the groups in terms of length of hospital stay (p ≤ 0.001), time off work (p ≤ 0.001),times to sitting on toilet and walking without pain (p=0.002 and p ≤ 0.001,respectively). The mean postoperative VAS scores were 5.2 ± 3.2 and 2.8 ± 2.2, respectively (p=0.02). The technique of sinotomy with good wound and surrounding skin care seems to be an ideal approach with high chance of cure. The patients returned to their routine in a short period of time.

Spontaneous rupture of tubal leiomyoma causing haemoperitoneum.

Leiomyomas are benign tumours that usually originate from the genital tract organs, particularly from the uterus. Spontaneous rupture of leiomyomas is a relatively rare condition. Herein, we report a 70 years old lady who was admitted through the emergency room with sudden abdominal pain. A ruptured mass originating from the fallopian tube, causing haemoperitoneum was revealed at laparotomy. Pathological examination revealed cellular leiomyoma.

Ingested bone fragment in the bowel: Two cases and a review of the literature.

Generally, ingested foreign bodies are excreted from the digestive tract without any complications or morbidity. In adults, ingestion of foreign bodies frequently occurs in alcoholics and elderly individuals with dentures. The most commonly ingested foreign bodies are food stuffs or their parts, such as fish bones or fragments of bone and phytobezoars. Sharp foreign bodies like fish and chicken bones can lead to intestinal perforation and peritonitis. We report herein two cases, one of bowel perforation and another of anal impaction, both caused by ingested bone fragments. Complications due to ingested bone fragments are not common and preoperative diagnosis remains a challenge and therefore it must be considered in susceptible cases.

Littoral-cell angioma of the spleen.

Littoral-cell angioma (LCA) is a rare vascular tumor of the spleen. It was thought to be a benign, incidental lesion. However, many recent reports have described it to be a malignant lesion with congenital and immunologic associations. We report a case of LCA of the spleen, which has been infrequently communicated in the literature. A 41-year-old female patient was admitted to our hospital with a three-week history of weakness, weight loss, anorexia, and intermittent upper abdominal pain which improved slightly with antacid medication.Imaging studies, including computed tomography (CT) and magnetic resonance imaging (MRI), showed multiple lesions in the spleen. Laparoscopic splenectomy was performed.

The efficacy of fibrin glue to control hemorrhage from the gallbladder bed during laparoscopic cholecystectomy.

OBJECTIVE: The aim of the study is to report our experience with fibrin glue application in the management of bleeding from the gallbladder bed during laparoscopic cholecystectomy, which could not be controlled by conventional methods. MATERIAL AND METHODS: Three hundred eighty-two patients underwent laparoscopic cholecystectomy. Fourteen patients with bleeding from the gallbladder bed, which could not be controlled by conventional methods, were analyzed retrospectively. RESULTS: Fibrin glue was used in 10 patients. Six (71%) were female and 4 were (29%) male. The mean age was 55.7 years. Fourteen patients were operated for the presence of symptomatic gallstones. Thirteen patients (92%) had a concomitant pathology. The mean time spent to maintain hemostasis was 23.9 minutes (15-35). Blood products were used in two patients with hemoglobin values under 8 mg/dL. Hemostasis could not be achieved in a patient despite fibrin glue application, and the operation was converted to open surgery. CONCLUSION: The application of fibrin glue for bleeding from the gallbladder bed during laparoscopic cholecystectomy can reduce conversion rates, further studies including more patients are required.

[Factors affecting mortality in acute mesenteric obstruction]. / Akut mezenterik tikanmada mortaliteyi etkileyen faktörler.

BACKGROUND: Acute mesenteric obstruction (AMO) is usually fatal. This study was designed to demonstrate the demographic characteristics and prognostic factors of affected patients. METHODS: The patients admitted to our emergency department and diagnosed as having AMO between January 2000 and December 2004 were investigated retrospectively. Their demographic characteristics, laboratory results, per-operative findings and mortality were investigated retrospectively. RESULTS: Thirty patients (18 males, 12 females; mean age: 67 [26-92]) were evaluated. 43.3% of patients survived. Surviving patients had statistically significantly lower alanine aminotransferase (ALT) but also higher pH and creatinine levels (p=0.0027, 0.0004, 0.02). Colonic involvement also increased mortality (p<0.001). Papaverine infusion, embolectomy and second-look operations had no effect on outcome. CONCLUSION: Preoperatively increased liver enzymes, acidosis, and colonic involvement indicated poor prognosis. Papaverine infusion, embolectomy and second-look operations showed no advantages with respect to survival.

Computed tomography severity index, APACHE II score, and serum CRP concentration for predicting the severity of acute pancreatitis.

CONTEXT: The assessment of the severity of pancreatitis is important for proper management of this challenging disease. A highly accurate system which could predict the severity and identify the local extent and complications of a serious inflammation, is beneficial for patient outcome. OBJECTIVE: The aim was to establish the value of the computed tomography severity index in predicting the severity of acute pancreatitis and to compare it with the accuracy of the APACHE II score and serum CRP concentrations. DESIGN: Prospective clinical series. PATIENTS: Fifty-five consecutive patients (37 women, 18 men; mean age 57 years) with a clinical and laboratory diagnosis of acute pancreatitis. INTERVENTIONS: Clinical evaluation, biochemical analysis of blood and contrast-enhanced abdominal CT. MAIN OUTCOME MEASURES: Computed tomography severity index within the first 5 days, serum CRP level, and clinical APACHE II score at 48 hours after admission. RESULTS: Thirteen patients had severe pancreatitis according to the Atlanta classification. The mean values of predictive markers in the mild and the severe pancreatitis groups were: computed tomography severity index 1.26 and 6.30 (P<0.001); APACHE II 4.14 and 8.61 (P<0.001); and CRP 96.0 mg/L and 192.4 mg/L (P<0.001), respectively. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy were calculated for the CTSI (greater than 3: 85%, 98%, 92%, 95%, and 95%), for APACHE II (equal to, or greater than 7: 62%, 86%, 57%, 88%, and 80%) and for CRP (equal to, or greater than 150 mg/L: 85%, 74%, 50%, 94%, and 76%). CONCLUSION: The computed tomography severity index is a reliable method for staging the severity of acute pancreatitis; moreover, CT has the ability of showing the local extent of the inflammation and the occurrence of local complications.
