RESUMEN
BACKGROUND: Simple appendectomy with a complicated appendicitis diagnosis could prove difficult, sometimes requiring ex-tended resection. Hence, we aimed to compare two procedures that are preferred for extended resection, ileocecal resection, and right hemicolectomy, in terms of patients' demographic data, preoperative laboratory values (white blood cell [WBC], Neutrophil-to-lymphocyte ratio [N/L], C-reactive protein [CRP]), operation times, postoperative complications, length of hospital stay, and 1-month mortality rates. METHODS: We retrospectively reviewed patients who underwent extended resection with the diagnosis of complicated appen-dicitis in our clinic from February 2015 to December 2020. We divided the patients into two groups those who underwent right hemicolectomy and those who underwent ileocecal resection. RESULTS: Among the 55 patients who underwent extended resection with the diagnosis of complicated appendicitis, 32 (58.1%) underwent right hemicolectomy and 23 underwent ileocecal resection (41.8%). The groups did not differ statistically significantly in terms of demographic characteristics, preoperative laboratory values (WBC, N/L, CRP), Clavien-Dindo classification scores, mean hospital stay, or 1-month mortality rates (p>0.005). However, there was a statistically significant difference between the groups in terms of operation time (p<0.001). CONCLUSION: Ileocecal resection is a safe procedure for patients diagnosed with complicated appendicitis who are scheduled for extended resection.

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.

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.

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.

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.
RESUMEN
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.
RESUMEN
INTRODUCTION: Temporary clamping of the hepatoduodenal ligament (the Pringle manoeuvre) is the most commonly used method to prevent intraoperative blood loss in liver surgery. Some side effects of the Pringle manoeuvre (PM) can occur. AIM: To investigate the effectiveness of preoperative immunonutritional support to prevent bacterial translocation (BT) in rats due to PM. MATERIAL AND METHODS: Forty Wistar albino rats were randomly divided into four groups. Groups 1 and 2 were fed with normal rat diet and water, and groups 3 and 4 were fed with enteral immunonutrition (Impact Glutamine) containing 1 g/kg/day amino acid in the preoperative period. Group 1 (n = 10) and 4 (n = 10) rats were treated only with laparotomy; group 2 (n = 10) and 3 (n = 10) rats were treated with PM for 30 min with laparotomy. After 30 min, relaparotomy was applied to all groups and portal blood, mesentery, spleen samples were taken for culture purposes. RESULTS: Proliferation in portal blood cultures was significantly higher in the samples from the normally fed group (group 2) in whom PM was applied, compared to the other groups (p < 0.001). No proliferation was observed in the PM-treated group (group 3), who also received preoperative immunonutritional support. CONCLUSIONS: Preoperative immunonutritional support is effective in the prevention of BT due to PM in rats.
