Inflammatory cloacogenic polyp in an adolescent - case report and review of the literature.

Inflammatory cloacogenic polyp is a rare lesion arising in the anal transitional zone. It is usually benign, but rare cases of malignant transformation are known. It is most commonly seen in the adult population from the fourth to the sixth decade of life, but it can be found among children and adolescents as well. The most common clinical symptoms include rectal bleeding and altered bowel habits, although some patients may be asymptomatic. Treatment involves transanal endoscopic microsurgery followed by a bowel regimen with stool softeners. We present the case report of a 14-year-old boy presenting with intermittent rectal bleeding in whom a polypoid lesion was found during digital rectal examination. The patient underwent proctosigmoidoscopy during which the suspicious lesion was removed by transanal endoscopic microsurgery and the histological diagnosis of inflammatory cloacogenic polyp was established. In the postoperative period, the patient was without any further problems. In this case report, we want to raise awareness of this rare diagnosis and emphasize its place in the differential diagnosis of rectal bleeding across all age groups.

Our experience with transanal total mesorectal excision (TaTME) procedures in middle and distal rectal tumors.

INTRODUCTION: Transanal total mesorectal excision (TaTME) is a relatively new approach in surgical treatment of rectal cancer. There are no clear indications when to choose this strategy. It is a technically demanding procedure for the surgeon with a long learning curve, which should also be taken into account in evaluation of this method. The results of both oncological and postoperative complications must be properly evaluated to explore the benefit of TaTME. The aim of this study is to assess the potential benefit of TaTME compared to other alternatives in middle and distal rectal tumors. METHODS: Retrospective evaluation of patients undergoing TaTME procedure performed by one team of surgeons between October 2014 and June 2019. The authors analyzed demographic indicators of the group of patients, tumor characteristics, specimen quality, early postoperative complications and the possibility of stoma reversal. RESULTS: A total of 93 patients underwent TaTME procedure for middle and distal rectal cancer. Mean BMI was 27.6 (4.8). T3 or T4 tumor was found in 73 (78.5%) patients, 68 (73.1%) patients had positive lymph nodes and 12 (12.9%) patients were treated for synchronous metastatic rectal cancer. Neoadjuvant therapy was used in 80 (86%) patients. Conversion to open laparotomy was necessary in one case (1%). Stapled anastomosis was performed in 37 (39.7%) cases, handsewn in 56 (60.2%). A positive circumferential resection margin (CRM) was found in 10 (10.7%) cases. Distal resection margin (DRM) was positive in 3 (3.2%) patients. Pathological analysis showed a complete mesorectum in 18 patients (19.4%), nearly complete in 39 (41.9%) and an incomplete mesorectum in 36 (38.7%). Complications in the first 30 days after primary surgery were observed in 38 (40.8%) patients, mainly for anastomotic leak (19 patients, 20.4%). Reoperation was required in 7 (7.5%) patients. Permanent colostomy had to be performed in 4 (4.3%) cases. No patient died after surgery. CONCLUSION: In a selected group of patients it is possible to perform resection using this approach with acceptable postoperative morbidity and quality of the specimen. We used TaTME procedure in patients expected to have difficult TME due to obesity, size and distal localization of tumor. The incidence of conversion to open surgery was very low. Further studies for long term oncological outcomes are needed.

[Paraneoplastic neurological syndromes in gynecological malignancies]. / Paraneoplastické neurologické syndromy u gynekologických malignit.

OBJECTIVE: The demonstration of life-threatening paraneoplastic syndrome with dominant neurological symptomatology in germinal ovarian malignancy. DESIGN: Literature review with case report. SETTING: Department of Gynecology and Obstetrics, Faculty of Medicine Masaryk University and University Hospital Brno. METHODS: The review outlines the issue of paraneoplastic syndromes. It describes the etiopathogenesis, the range of clinical symptoms, the diagnostic and therapeutic possibilities, along with a relevant case study which focuses on the paraneoplastic neurological symptoms in malignant germinal ovarian tumor. CONCLUSION: Although paraneoplastic symptomatology is rather rare, it constitutes an important part of the clinical picture of malignant tumors. In a number of cases, the paraneoplastic neurological syndrome (PNNS) symptoms precede the actual tumor diagnosis. The awareness of this connection can thus be important in early diagnostics, which in turn can significantly affect a patients prognosis. Another important benefit of familiarity with the symptoms of neurological paraneoplasia is the fact that some PNNS are associated with specific tumors. Interdisciplinary cooperation is necessary in the case of PNNS for early tumor diagnostics. Treatment of the primary tumor is the key in diagnosed malignancies. With effective oncological treatment, adequate regression of paraneoplastic symptoms can be observed.

[Complete mesocolic excision during right hemicolectomy]. / Kompletní mezokolická excize u pravostranné hemikolektomie.

INTRODUCTION: Complete mesocolic excision (CME) ensures the removal of all sentinel and regional lymph nodes during colon cancer surgery. For right-sided hemicolectomy it is essential to dissect the wall of vena mesenterica superior, which increases the risk of injuring surrounding organs. So far, no randomized studies comparing long-term oncological results of standard right hemicolectomy and hemicolectomy with CME have been published. METHOD: 83 patients operated for colon carcinoma in 2014 and 2015 were included in this study, all of them undergoing right-sided hemicolectomy using laparotomy access. The standard procedure was done in 63 cases and hemicolectomy with CME was done in 20 cases. We compared the incidence of complications, and the characteristics and descriptions of obtained specimens evaluated by a pathologist for both groups. RESULTS: The operation times of right-sided hemicolectomies with CME was longer by 20 minutes on average. The incidence of postoperative complications was similar in both groups. Pancreatic fistula in the group of patients undergoing right-sided hemicolectomy with CME was an unusual complication; the fistula was healed through conservative treatment. Comparing the resecate parameters, we found no significant differences in the lengths of the resected terminal ileum. But the length of the resected colon was significantly longer for the CME technique (median 42 cm versus 22 cm). The incidence of lymph node metastases was similar in both groups. However, the total number of removed lymph nodes in the group with CME was significantly higher (median 23). CONCLUSION: Right-sided hemicolectomy with complete mesocolic excision offers the removal of more lymph nodes than the standard technique. The central vascular ligation technique elongates the operation time and may be associated with more intraoperative injuries. Introduction of the concept of complete mesocolic excision is derived from an effort to standardize the surgical technique for colon cancer resection.Key words: right-sided hemicolectomy complete mesocolic excision colon cancer lymphadenectomy.

[Warning about risk of invasive infections in splenectomized patients. Experiences from University Hospital Brno, Czech Republic, in 2011]. / Upozornení na nebezpecí invazivních infekcí u splenektomovaných pacientu. Zkusenosti z FN Brno 2011.

Syndrome of fulminant sepsis in splenectomized (overwhelming postsplenectomy infection - OPSI) is feared and often fatal infectious complication in patients after splenectomy. The risk of syndrome of fulminant sepsis in splenectomized in these persons persists lifelong and doesn't diminish during the time. Etiologically, encapsulated bacterias like Streptococcus pneumoniae, Haemophilus influenzae group b and Neisseria meningitidis are involved. As the mortality of syndrome of fulminant sepsis in splenectomized is very high, it is indispensable to educate and vaccinate persons in risk. The authors present case reports of three splenectomized patients who were hospitalized for invasive pneumococcal infection in the University Hospital Brno, Czech Republic, in 2011.
