RESUMO

Introduction: The staple line (SL) leak remains one of the most serious complications after laparoscopic sleeve gastrectomy (LSG). The present study aims to determine whether reinforcing the SL with sutures is effective in maintaining tissue integrity. Materials and Methods: LSG Specimens of 60 patients were ex vivo studied. The specimens were divided into three groups: In group 1, the entire SL was reinforced, while the upper half part of the SL was reinforced from fundus to antrum in group 2. The SL was not reinforced in group 3. Then, the pressure inside the sample was increased, and the bursting pressure location and pressure value during the bursting were recorded. Results: The bursting pressure was significantly higher in entire and half oversewed SL groups than the none reinforced group (group 1: 115 mmHg [95-170]; group 2: 95 mmHg [80-120]; group 3: 40 mmHg [22-60], respectively, [P < .001]). The most common site of bursting was in the middle ⅓ of SL (35, 53.8%), followed by the proximal ⅓ part of SL (18, 27.7%), and the distal ⅓ part of SL (12, 18.5%), respectively. The bursting site was significantly more frequent in the corpus than the other parts of the SL (P = .013). Conclusion: Reinforcing the SL with sutures preserves tissue integrity. Although bursting was most frequently observed in the corpus region ex vivo, the fact that almost all real-life leaks develop in the area close to the Angle of His. This situation suggests that strengthening the suture line with reinforcement alone will not be protective enough against leaks in the fundus line, and factors such as tissue ischemia may be considered.

RESUMO

Background Ambulatory anorectal surgeries have increased in the last few years. This clinical study aimed to compare general operating room conditions with outpatient procedures for simple anal fistulas in terms of healing success, recurrence, cost, complications, and sustainability. Methodology Only primary fistulotomy and seton application for simple anal fistulas were retrospectively analyzed. Results Two-hundred fifty patients (73.7%) were male, and 89 (26.3%) were female. Sixty patients (17.7%) were treated in the operating room, and 279 (82.3%) were treated in the outpatient clinic conditions. Of the ambulatory surgeries, 160 patients underwent fistulotomy and 119 patients loose seton. On the other hand, 34 patients underwent fistulotomy and 26 patients loose seton in operating room conditions. No significant difference was found between the groups according to the distribution of age, gender, complications, and recurrence (P > 0.05). Cost-effectiveness assessment according to the place (ambulatory/operating room) and type of operation (fistulotomy/loose seton) reveals that ambulatory surgery provides significantly more savings (P < 0.001). Conclusions For simple anal fistulas, ambulatory anorectal surgery is a safe approach that can be performed at a lower cost than operating room conditions.

RESUMO

INTRODUCTION: Postoperative peritoneal adhesions formed after abdominal surgery still continue to exist as an unresolved health problem. AIM: The aim of the present study is to examine whether omega -3 fish oil has a preventive effect on postoperative peritoneal adhesions. METHODS: Twenty-one female Wistar-Albino rats were separated into 3 groups (sham, control, and experimental group), each consisting of 7 rats. In sham group, only laparotomy was performed. Both in control and experimental group rats; the right parietal peritoneum and cecum were traumatized to form petechiae. Following this procedure, unlike the control group, the abdomen was irrigated with omega-3 fish oil in the experimental group. Rats were re-explored on the 14th postoperative day and adhesions were scored. Tissue samples and blood samples were taken for histopathological and biochemical analysis. RESULTS: None of the omega-3 fish oil given rats developed macroscopically postoperative peritoneal adhesion (P=0.005). Omega-3 fish oil formed an anti-adhesive lipid barrier on injured tissue surfaces. Microscopic evaluation revealed diffuse inflammation with excessive connective tissue and fibroblastic activity in control group rats while foreign body reactions were common in omega-3 given rats. The mean amount of hydroxyproline in samples from injured tissues was significantly lower in omega-3 given rats than in control rats. (P=0.004). CONCLUSION: Intraperitoneal application of omega-3 fish oil prevents postoperative peritoneal adhesions by forming an anti-adhesive lipid barrier on injured tissue surfaces. However, further studies are needed to determine whether this adipose layer is permanent or will be resorbed over time.

RESUMO

OBJECTIVE: To compare postoperative morbidity and mortality results in patients with and without endoscopic and percutaneous transhepatic biliary drainage due to obstructive jaundice caused by a periampullary tumor and to examine the effect of intervals until surgery on postoperative morbidity and mortality in patients who underwent preoperative biliary drainage (BD). METHODS: Patients were divided into 3 groups according to their BD status. Group1, no biliary drainage (NBD), Group2, Endoscopic biliary drainage (EBD), Group3, Percutaneous transhepatic biliary drainage (PBD). Patients who underwent biliary drainage before pancreaticoduodenectomy (PD) were divided into 3 intervals according to the time interval between drainage and surgery: Short interval; patients undergoing surgery in 21 days and <, Medium interval; between 22-42 days, Long interval; 43 days and >. Groups and intervals were compared in terms of postoperative morbidity and mortality. RESULTS: Of the 122 patients who underwent PD, 76 (62.3%) were male, and 46 (37.7%) were female. Within these patients, 47 (38.52%) had NPD, 42 (34.42%) had EBD, and 33 (27.05%) had PBD. The rate of postoperative Grade B and C fistula was higher in the groups that underwent preoperative drainage compared to the group without preoperative drainage (p = 0.007). CONCLUSION: It was determined that the postoperative complication rate was lower in patients who did not undergo BD compared to patients who underwent biliary drainage. Besides, the endoscopic drainage method was observed to be associated with fewer complications than the percutaneous transhepatic drainage method. KEY WORDS: Preoperative biliary drainage, Pancreaticoduodenectomy, Periampullary tumors, Post procedure complication, Timing.

RESUMO

BACKGROUND: One of the most misdiagnosed appendicular pathologies is lymphoid hyperplasia (LH) that can be managed con-servatively when identified early and is self-limiting. The aim of this retrospective study was to compare acute appendicitis (AA) with LH in terms of hematological parameters to determine whether there is a hematological predictor to distinguish the two diseases. METHODS: Complete blood cell counts of patients with AA were compared with those having LH. RESULTS: One-hundred-ninety-five patients (118 male/77 female) underwent appendectomy. Histopathological examination re-vealed acute AA in 161 patients (82.6%), and negative appendectomy (NA) in 19 patients (9.7%). Of the NA specimens, 16 were LH (8.2%). Thirteen patients (6.7%) had AA with simultaneous LH. White blood cell count (p=0.030, neutrophil (p=0.009), neutrophil per-centage (p=0.009), and neutrophil/lymphocyte ratio (p=0.007) were significantly higher in AA whereas lymphocyte count (p=0.027), lymphocyte percentage (p=0.006) were significantly higher in LH. Multi logistic regression analysis revealed white blood cell count as the only independent predictor in distinguishing AA from LH with a 69.1% sensitivity, 80.0% specificity, 77.5% positive predictive value, and 72.1% negative predictive value. The cut-off value for white blood cell count was 11.3 Ku/L, and every one unit (1000/mm3) increase in white blood cell count raises the risk of AA by 1.24 times, while values below this value will increase the likelihood of LH. CONCLUSION: The most predictive complete blood count parameter in distinguishing LH from AA appears to be as white blood cell count.

RESUMO

BACKGROUND: In colorectal cancer (CRC), the mutation of the K(N)RAS gene has a significant impact on the clinical course, and is associated with a negative prognosis. We aim to present the morbidity and long-term results in patients with wild/mut-K(N)RAS, undergoing CRC surgery. METHODS: A total of 116 patients who underwent surgery for colorectal cancers with wild/mut-K(N)RAS were included in this retrospective study. The patients were divided into two groups: wild-K(N)RAS patients (Group 1) and mutant- K(N)RAS patients (Group 2). Results were evaluated for clinical, operative, morbidity and long-term survival outcomes. MATERIALS AND METHODS: The highest surgical site infection (SSI) rate (OR=140.339)(4.303-4581.307)(P=0.005) was seen in patients given Bevacizumab during neoadjuvant treatment. Meanwhile, the SSI site infection rate was at its lowest in cases where minimally invasive surgery was preferred (OR=0.062)(0.006-0.628)(P=0.019). In addition, the overall median survival rate for the total cohort was 38±3.1 (31-44) months. Multivariate analysis showed that CEA (>5ng/mL)(HR 2.94)(1.337-6.492))(P=0.007); tumor stage (P=0.034), T(T4) stage (HR 1.91)(1.605-252.6)(P=0.02); metastasectomy/ablation (HR 0.19)(0.077-0.520)(P=0.001); the number of removed metastatic lymph nodes (HR 1.08)(1.010-1.155)(P=0.025); tumor implant or nodule (HR 2.71)(1.102-6.706)(P=0.03); curative resection (HR 2.40)(0.878-6.580)(P=0.042) to be factors affecting the overall survival rate. CONCLUSION: Treatment with Bevacizumab during the neoadjuvant period in mut-K(N)RAS cases, surgical technique and complications of Grade 3 or higher are risk factors for SSI on morbidity in patients with mut/wild-K(N)RAS undergoing colorectal cancer surgery. Moreover, CEA (>5ng/mL), tumor stage, T stage, metastasectomy/ablation, the number of removed metastatic lymph nodes, tumor implant/nodule and curative resection are risk factors on the overall survival rate. KEY WORDS: Bevacizumab, Colorectal cancer, K(N)RAS mutation, Morbidity, Mortality.

RESUMO

BACKGROUND: The effect of bariatric surgery on thyroid hormone changes yielded inconsistent results. The aim of the present study was to assess the change of thyroid hormone levels following laparoscopic sleeve gastrectomy (LSG), with or without antral preservation (AP). METHODS: Thyroid hormones (TSH, FT3, FT4) were examined preoperatively, at the end of the first postoperative month, and first postoperative year. Secondly, antral resection (AR) and AP were compared at inducing weight loss and thereby affecting thyroid hormone levels. RESULTS: Euthyroid obese patients (86 female/20 male) underwent LSG. Of these, 58 patients underwent AR and 48 patients AP. The mean FT3 levels significantly decreased both in the first postoperative month and the first year (P < 0.001), whereas mean TSH levels decreased significantly in the first postoperative year (P < 0.001). FT4 levels remained nearly unchanged (P = 0.517). Postoperative first year body mass index (BMI) loss, excess BMI loss percentile (%EBMIL), and total body weight loss percentile (%TWL) were significantly higher in AR group than the AP group (P ≤ 0.01). When the change in thyroid hormone levels was analyzed by pyloric distance according to time periods, no significant difference was found in TSH and FT4 levels (P > 0.05); however, reduction in FT3 levels was significantly greater in patients with AR than in AP patients (P = 0.028). CONCLUSION: LSG promotes significant reduction in TSH and FT3 levels, whereas FT4 levels remain unchanged. LSG with AR provides more weight loss in short term and appears to be more effective at lowering FT3 levels.

RESUMO

BACKGROUND: Sclerosing angiomatoid vascular transformation (SANT) is a rare vascular disease of the spleen, which is difficult to diagnose due to its pre-intervention appearance of malignancy. Case Report: An 85-year-old male was transferred to our clinic for thrombocytopenia and splenic mass. A contrast enhanced abdominal CT and MRI showed nodular lesions, the largest 50mm in diameter, and several areas of heterogeneous contrast field involvement in the spleen parenchyma. Laparoscopic splenectomy was performed with normal range of platelet level. The patient's postoperative course was uneventful and he was discharged on the 6th postoperative day. Histopathology revealed SANT. The patient is now in the 18 th month of remission with platelet levels within normal range and with no recurrence. RESULTS: Between 2004 and April 2020, a total of 230 SANT patients who underwent laparoscopic or open splenectomy or biopsy were reported in the literature. Most patients were female (52.1%), and the median age was 46 years (9 weeks-85 years). Most patients were asymptomatic (56%). Open splenectomy was performed on 166 patients (72.1%),laparoscopic splenectomy on 35 patients (15.2%) and laparoscopic partial splenectomy on 15 patients (6.5%). The median operation time and spleen weight were 143 minutes (88-213) and 260gr (68-2,720), respectively. Median follow-up time was 12 months (0-166). No recurrence was seen in patients undergoing total splenectomy. CONCLUSION: SANT is an unusual disease of the spleen. In the light of this systematic review, a minimally invasive method for total or partial splenectomy,specifically laparoscopy, can be preferred as the treatment of choice.

RESUMO

OBJECTIVE: The impact of extended antral resection (AR) after laparoscopic sleeve gastrectomy (LSG) on clinical results is still not clearly elucidated with conflicting results. Our study aimed to determine whether AR is superior to antral preservation (AP) regarding clinical results. METHODS: Patients were divided into two groups according to the distance of gastric division as AR group (2cm from pylorus) and AP group (6cm from pylorus). Postoperative excess weight loss percentile (%EWL) and total body weight loss percentiles (%TBWL) at the end of first, 6th and 12 months were compared. Secondly, metabolic parameters and complications were compared. RESULTS: The first 68 patients underwent AP, and the following 43 patients underwent AR. Although statistically not significant, AR achieve more %EWL and %TBWL at the end of the first year, (P>0.05). On the other hand, metabolic parameters were similar at the end of the first year, (P>0.05). Resolution of comorbidities were statistically not different, (P>0.05). Staple line leak occurred in two patients of the AR group (4.7%) and two patients of the AP group (2.9%), (P>0.05). CONCLUSION: Both AR and AP seem to be equally effective in resolution of metabolic response. Although statistically not significant- AR provided more %EWL and %TBWL at the end of 12 months.

RESUMO

OBJECTIVES: Minimal invasive surgery is one of the most popular treatment approaches which is safe and effective in experienced hands in different clinical practices. In the present study, we aimed to evaluate the risks factors for conversion to open splenectomy and the performance of indirect hilum dissection technique. MATERIAL AND METHODS: A total of 56 patients who underwent laparoscopic or robotic splenectomy for isolated spleen diseases were included into the study. Patients were divided into two groups as robotic or laparoscopic splenectomy (Group 1; n= 48) and conversion to open surgery (Group 2; n= 8). Patients were retrospectively evaluated according to clinical, biochemical, hematological and microbiological parameters and morbidity. RESULTS: No statistically significant difference was found between the groups in terms of age, gender, body mass index (BMI), ASA score, co-morbid disease, operation time, hospital stay, follow-up period, accessory spleen, diagnosis, international normalized ratio (INR), red cell distribution width (RDW), platelet distribution width (PDW), platelet to lymphocyte ratio (PLR), neutrophil to lymphocyte ratio (NLR), reapplication, splenosis, surgical site infection, vascular thrombus and incisional hernia (p> 0.05). On the other hand, intraoperative splenic hilum hemorrhage and increased spleen size (p <0.05) were higher in the conversion to open surgery group. In logistic regression analysis, intraoperative splenic hilum hemorrhage (B= 4.127) (OR= 61.974) (95% CI= 3.913-981.454) (p= 0.003) and increased spleen volume (B= 3.114) (OR= 22.509) (95% CI= 1.818-278.714) (p= 0.015) were found as risk factors for conversion to open surgery. CONCLUSION: Intraoperative hemorrhage from the splenic hilum and increased spleen volume (> 400 cm3) are risk factors for conversion to open splenectomy in patients undergoing elective robotic or laparoscopic splenectomy. Indirect splenic hilum dissection can decrease intraoperative hemorrhage and conversion to open surgery.

RESUMO

OBJECTIVE: Endoscopic retrograde cholangiopancreatography (ERCP)-related perforations occur in 0.3-0.6% of patients. The treatment of retroperitoneal paravaterian perforations (type II), which develop during endoscopic sphincterotomy or precut sphincterotomy, remains a matter of debate. We aimed to evaluate the efficacy of fully covered self expandable metal stent (Fc-SEMS) placement in the treatment of type II perforations. METHODS: The study was conducted in a tertiary ERCP reference center of Turkey between December 2013 and June 2016. Patients with type II ERCP-related perforation constituted the study group. Type II perforations were treated by insertion of an Fc-SEMS (10 mm × 60 mm) during the ERCP procedure or intraoperatively by surgery-endoscopy rendezvous technique, if biliary cannulation could not be achieved. RESULTS: A total of 2689 ERCPs were performed. ERCP-related perforation was observed in 12 procedures (0.4%). Eight patients had Stapfer type II perforations, which developed during endoscopic sphincterotomy in seven patients and precut sphincterotomy in one patient. Fc-SEMSs were inserted during the ERCP procedure in seven patients and intraoperatively by surgery-endoscopy rendezvous technique in one patient. None of the patients developed fever, hemodynamic instability, or peritoneal signs. Stents were removed after a median duration of 9 (3-14) days. All of the patients were uneventfully discharged after an average hospital length of stay of median 5 (1-9) days. CONCLUSION: Fc-SEMSs are highly effective in the nonoperative treatment of type II perforations and their intraoperative insertion in patients with unsuccessful cannulation may facilitate surgery by eliminating the need for duodenum repair surgery.

RESUMO

INTRODUCTION: Renal cell carcinoma (RCC) is a rare tumor that comprises only 3% of adult cancers, while renal parenchymal tumors constitute 85% of all RCC cases. RCC frequently metastasizes to the lungs, bones, brain or liver; however, the gastrointestinal tract, particularly the colon, is an unusual location for metastasis. CASE REPORT: A 63-year-old male patient was admitted complaining of hematochezia. The patient had undergone left-side nephrectomy for RCC, 5 years previously. Computed tomography and colonoscopy detected a splenic flexure tumor and after left hemicolectomy and splenectomy, histopathological examination revealed a colonic metastasis of the renal cell carcinoma. DISCUSSION: Cases of colonic metastasis following resection of a RCC are uncommon in the literature and their location can be very varied, but include the sigmoid colon, splenic flexure, transvers colon and hepatic flexure. Recurrence of RCC is frequently seen during the first three postoperative years, and surgical resection is suggested for solitary non-metastatic tumor. CONCLUSION: RCC rarely metastases to the colon but may occur years after curative resection. Therefore, RCC patients should be closely followed for the long term. In case of isolated metastasis, long-term survival can be achieved with R0 resection.

RESUMO

BACKGROUND/AIMS: Several studies recommend prompt laparoscopic cholecystectomy (LC) following endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis. However, histopathological alterations in the gallbladder during this time interval and the role played by ERCP in causing these changes have not been sufficiently elucidated. To compare early period LCs with delayed LCs following common bile duct stone extraction via ERCP with regard to operation time, hospitalization period, conversion to open cholecystectomy rate, morbidity, mortality, and histopathological alterations in the gallbladder wall. MATERIALS AND METHODS: A total of 85 patients were retrospectively divided into three groups: early period LC group (48-72 h; n=30), moderate period LC group (72 h-6 weeks; n=25), and delayed period LC group (6-8 weeks; n=30). RESULTS: The operation time was significantly shorter, and the total number of complication rates and hospital readmission was significantly less frequent in the early period LC group (p<0.05). Ultrasound showed a significantly thicker gallbladder wall (>3 mm) in the moderate and late period LC groups than in the early period LC group (p<0.001). Culture growth was significantly higher, and fibrosis/collagen deposition in the gallbladder wall with injury to the mucosal epithelium was significantly more frequently detected by histopathological examination in the moderate and late period LC groups than in the early period LC group (p<0.05). CONCLUSION: Early period LC following stone extraction by ERCP is associated with shorter operation time, fewer fibrotic changes in the gallbladder, and lower risk for the development of complications. Therefore, LC can be performed safely in the early period after ERCP.

RESUMO

BACKGROUND: The Karaman score is a novel diagnostic scoring system consisting of 6 parameters. The aim of the present study was to assess the diagnostic performance of the Karaman score in comparison with the Alvarado score. METHODS: A total of 200 patients who underwent an appendectomy were enrolled in the study (research registry number: 2290). RESULTS: The cutoff threshold of the Karaman score in distinguishing acute appendicitis from negative appendectomy was ≥9 with 84.3% sensitivity, 64.7% specificity, 92.1% positive predictive value (PPV), and 45.8% negative predictive value (NPV). The cutoff threshold of the Alvarado score in distinguishing acute appendicitis from negative appendectomy was ≥8 with 72.9% sensitivity, 70.6% specificity, 92.4% PPV, and 34.8% NPV. In multivariate logistic regression analysis, an Alvarado ≥8 score (Odds ratio [OR]:6.644, 95% confidence interval [CI]: 2.854-15.466; p<0.001) and a Karaman ≥9 score (OR:10.374, 95% CI: 4.383-24.558; p<0.001) were each individually predictive in distinguishing acute appendicitis from negative appendectomy when correction was made according to age and gender. However, when both scores were evaluated together, the Alvarado score ≥8 lost its efficacy (OR:1.838, 95% CI: 0.517-6.530; p=0.347), whereas the Karaman score ≥9 retained its predictive power (OR:6.586, 95% CI: 1.893-22.917; p=0.003). CONCLUSION: The Karaman score was more predictive than the Alvarado score in distinguishing acute appendicitis from a negative appendectomy.

BACKGROUND: The aim of this study was to evaluate the risk factors for morbidity in cases of walled-off pancreatic necrosis (WOPN) and the performance of continuous postoperative lavage (CPL) for patients who demonstrated resistance to a minimally invasive approach. METHODS: The study enrolled 19 of 28 consecutive patients with WOPN who underwent surgical treatment or an endoscopic necrosectomy at Sakarya University Education and Research Hospital. The patients were divided into 2 groups according to the length of time from the first diagnosis of acute pancreatitis (AP) (Group 1, n=19) to preoperation or endoscopic necrosectomy (Group 2) (n=19). All of the cases were retrospectively evaluated and compared in terms of demographic features, operative features, and complications. RESULTS: No statistically significant difference was found between the number of complications or the duration of hospital stay in terms of age, body mass index, size of the walled-off pancreatic necrosis, American Society of Anesthesiologists score, Ranson's criteria, operation time, and duration from AP to endoscopic necrosectomy or operation (p>0.05). Performance of an endoscopic necrosectomy was determined to be correlated with a decrease in the number of complications (B=-0.626, 95% confidence interval [CI]: -0.956 to -0.296; p<0.001), and when a high neutrophil-to-lymphocyte ratio (NLR) was detected at first admission, the number of complications was greater (B=0.032, 95% CI: 0.009-0.055; p=0.01). Reproduction in a culture and male gender were found to be risk factors for a prolonged hospital stay (B=0.669, 95% CI: 0.365-0.973; p<0.001), (B=0.484, 95% CI: 0.190-0.778; p=0.003), respectively. CONCLUSION: CPL is a safe and effective surgical treatment approach for WOPN. Reproduction in a culture, male gender, and a high NLR on first admission and a negative or not-available endoscopic necrosectomy were determined to be risk factors for a poor prognosis.

RESUMO

BACKGROUND/AIMS: Currently, forceful endoscopic pneumatic balloon dilatation (PBD), laparoscopic Heller myotomy (LHM) with or without an anti-reflux procedure, and peroral endoscopic myotomy are the preferred treatment options for achalasia. The aim of the present study was to retrospectively compare postoperative outcomes after LHM plus Dor fundoplication (DF) between patients who underwent prior endoscopic balloon dilatation and those who did not. MATERIALS AND METHODS: Sixty-five patients who underwent HM+DF between January 2008 and December 2016 were retrospectively analyzed. Of these, 45 had a history of endoscopic PBD. Pre- and postoperative achalasia symptoms, including weight loss, dysphagia, heartburn, and regurgitation, were evaluated using the Eckardt score. RESULTS: Fifty (76.9%) patients underwent laparoscopic surgery and 15 (23.1%) underwent open surgery. When patients were compared according to the presence of preoperative endoscopic PBD, no significant difference were observed in terms of age, sex, preoperative lower esophageal sphincter pressure, operation time, hospitalization period, and follow-up period (p>0.05). The mean Eckardt score at the first postoperative year was significantly lower than the preoperative Eckardt score (4.51±1.8 vs. 0.52±0.7; p<0.001). In contrast, no significant difference was found between patients with and without previous PBD on the pre- and postoperative Eckardt scores (p=0.43). CONCLUSION: HM+DF is an effective procedure in relieving achalasia symptoms as a first-line therapy as well as in individuals unresponsive to repeated endoscopic PBDs.

RESUMO

An infected material in the gastrosplenic area after laparoscopic sleeve gastrectomy (LSG) due to hematoma or staple line leak has the potential to spread of the bacterial content to the liver which can result in pyogenic liver abscess. Presently described is a thirty-seven-year-old female patient with unilocular pyogenic liver abscess two weeks after LSG. The abscess resolved by Ultrasound guided percutaneous drainage plus intravenous antibiotic treatment. Review of the literature regarding 3 other cases with liver abscess after LSG is also presented.

RESUMO

BACKGROUND/AIMS: Postoperative pancreatic fistula (POPF) is the most common cause of morbidity and mortality after distal pancreatectomy (DP). The aim of the present study is to determine the risk factors that can lead to POPF. MATERIALS AND METHODS: The study was conducted between January 2008 and December 2012. A total of 96 patients who underwent DP were retrospectively analyzed. RESULTS: Overall, 24 patients (25%) underwent laparoscopic distal pancreatectomy (LDP) and 72 patients (75%) open surgery. The overall morbidity rate was 51% (49/96). POPF (32/96, 33.3%) was the most common postoperative complication. Grade B fistula (18/32, 56.2%) was the most common fistula type according to the International Study Group on Pancreatic Fistula definition. POPF rate was significantly higher in the minimally invasive surgery group (50%, p=0.046). POPF rate was 58.6% (17/29) in patients whose pancreatic stump closure was performed with only stapler, whereas POPF rate was 3.6% (1/28) in the group where the stump was closed with stapler plus oversewing sutures. Both minimally invasive surgery (OR: 0.286, 95% CI: 0.106-0.776, p=0.014) and intraoperative blood transfusion (OR: 4.210, 95% CI: 1.155-15.354, p=0.029) were detected as independent risk factors for POPF in multi-variety analysis. CONCLUSION: LDP is associated with a higher risk of POPF when stump closure is performed with only staplers. Intraoperative blood transfusion is another risk factor for POPF. On the other hand, oversewing sutures to the stapler line reduces the risk of POPF.

RESUMO

INTRODUCTION: Porto-mesenteric venous thrombosis (PMVT) is a rare but fatal complication after bariatric surgery. However, an increasing number of PMVT complications have been observed in the last years after laparoscopic sleeve gastrectomy (LSG) operations. CASE REPORT: A 35-year-old male was admitted to the emergency clinic in a septic status with a sudden once of abdominal pain and vomiting. The patient underwent laparoscopic sleeve gastrectomy (LSG) 15 days ago. His physical examination revealed diffuse abdominal tenderness. Abdominal computerised tomography showed a thrombus which was elongated from vena mesenterica superior to vena porta. An emergent laparotomy was performed. A 40 cm of ischemic small bowel segment which began at the 60th cm of Treitz ligament was resected. The gastrointestinal continuity was provided by an end-to-end anastomosis. Patient's postoperative course was uneventful. He was discharged on the 7th postoperative day and was medicated on oral anticoagulation (Warfarin 5 mg/day) for six months. RESULTS: A total of 104 morbidly obese patients who developed PMVT after bariatric surgery are reported in the English literature between 2004 and April 2017. Most of the patients were female (63 cases, 60.5%). The median age was 42.5 years (14-68) and the median body mass index (BMI) was 44 kg/m2 (31.8-74.6). The most common cause of coagulopathy disorders was protein C and/or S deficiency (9.6%) followed by prothrombin gene mutation (6.7%). LSG was performed in 83 patients (78.8%) and the median intraoperative pressure was 15 mmHg (14-20). The median operation time was 70 min (min-max: 37-192). Fifty-five patients (52.8%) underwent preoperative oral anticoagulant prophylaxis. The median time for PMVT development was 14 days (min-max: 1-453). Of the 104 patients with PMVT, 75 cases (72.1%) underwent postoperative anticoagulant agents such as low-molecular weight heparin (LMWH), heparin drip or infusion, streptokinase or warfarin, whereas the remaining did not receive prophylactic medication. CONCLUSION: PMVT after sleeve gastrectomy is a rare but fatal complication. Therefore, anti-coagulation prophylaxis with LMWH should be considered at least one month postoperatively.
