Embryological, anatomical, and immunological differences between the right-sided and left-sided colons are well known, but the difference in oncological behavior of colon tumors has only recently become the main subject of studies. Published articles propose that there is a difference not only in symptoms, but also in survival. Our aim was to analyze the clinicopathological and oncological differences among our patients who had been operated for colon cancer in our department. We examined the historical data of our patients who underwent colon resection for malignancy between 1st of January 2016 and 31st of December 2018. Tumor markers, histological results, postoperative complications, and oncological therapies were investigated. The primary outcome was overall survival. We analyzed our patients’ survival data with Kaplan–Meier log-rank test and Cox regression analysis. In our study, 267 patients were enrolled. One hundred thirty-three (49.8%) patients had right-sided colon cancer; 134 (50.2%) patients had left-sided colon cancer. Patients with right-sided colon cancer were significantly more likely to have mucinous adenocarcinoma (p = 0.037). No significant differences were revealed in overall survival between right-sided colon cancer and left-sided colon cancer patients (p = 0.381). Additional subgroup analysis showed that there were no significant differences in overall survival for laterality neither in the metastatic group (p = 0.824) nor in the non-metastatic group (p = 0.345). Based on the conflicting previous study results, our findings repeatedly highlight that the relationship between tumor location in the colon and overall survival is not straightforward.
Összefoglaló. Egy 46 éves nőbeteg esetét ismertetjük, akinél láz és görcsös hasi fájdalom miatt kezdődött kivizsgálás. A hasi ultrahangvizsgálat során a colon transversum területén megvastagodott falú konglomerátum volt látható. A kolonoszkópia során organikus eltérés nem igazolódott. A hasi komputertomográfiás vizsgálat retroperitonealis térfoglalást írt le, ezért onkológiai bizottság javaslata alapján műtét mellett döntöttünk. Egy hónappal a panaszok jelentkezése után megtörtént a műtét, melynek során úgy tűnt, hogy egy megközelítőleg 5 × 8 centiméteres, a vékonybélből kiinduló, a colon ascendenst és a sigmabelet is érintő, daganatnak imponáló terimét találtunk. Jobb oldali hemicolectomiát végeztünk, és reszekáltuk a sigmabélfal részletét. A szövettani vizsgálat malignitást nem igazolt, hanem a bélfallal összefüggést nem mutató, mesenterialis actinomycosist írt le. A hasi, mesenterialis actinomycosis ritka kórkép, mégis fontos, hogy gondoljunk rá mint differenciáldiagnosztikai lehetőségre, így a beteg a lehető leghamarabb megkaphatja a megfelelő kezelést. Esettanulmányunk bemutatásával a kórkép ismeretének fontosságára szeretnénk felhívni a figyelmet. Orv Hetil. 2021; 162(3): 116–119. Summary. We present the case of a 46-year-old female, who presented with fever and abdominal pain. Abdominal ultrasound revealed a thickened-walled conglomerate near the transvers colon. Colonoscopy did not show any organic abnormality. Abdominal computed tomography described a retroperitoneal mass, so we decided on surgery based on the multidisciplinary team decision. One month after the onset of symptoms, laparotomy was performed, and it seemed that we found an approximately 5 × 8 centimetre tumour attached to the small intestine involving the ascending and sigmoid colon. We performed right hemicolectomy and sigmoid colon wall resection. Histology result showed mesenteric actinomycosis with no connection to the intestinal wall, no malignancy was revealed. Although the abdominal, mesenteric actinomycosis is a rare disease, it is important to think of it as a differential diagnostic option, so the patient can get proper treatment and cured sooner. Our aim with presenting this case report is to highlight the significance of this disease. Orv Hetil. 2021; 162(3): 116–119.
Purpose Based on recent scientific evidence, bariatric surgery is more effective in the management of morbid obesity and related comorbidities than conservative therapy. Pylorus preserving surgical procedures (PPBS) such as laparoscopic single-anastomosis duodeno-jejunal or duodeno-ileal bypass with sleeve gastrectomy are modified duodenal switch (DS) surgical techniques. The duodeno-jejunal bypass liner (DJBL) is a novel surgical method in the inventory of metabolism focused manual interventions that excludes duodeno-jejunal mucosa from digestion, mimicking DS procedures without the risk of surgical intervention. The aim of this article is to summarize and compare differences between safety-related features and weight loss outcomes of DJBL and PPBS. Methods A literature search was conducted in the PubMed database. Records of DJBL-related adverse events (AEs), occurrence of PPBS-related complications and reintervention rates were collected. Mean weight, mean body mass index (BMI), percent of excess of weight loss (EWL%), percent of total weight loss (TWL%) and BMI value alterations were recorded for weight loss outcomes. Results A total of 11 publications on DJBL and 6 publications on PPBS were included, involving 800 and 1462 patients, respectively. The baseline characteristics of the patients were matched. Comparison of DJBL-related AEs and PPBS-related severe complications showed an almost equal risk (risk difference (RD): −0.03 and confidence interval (CI): −0.27 to 0.21), despite higher rates among patients having received endoscopic treatment. Overall AE and complication rates classified by Clavien-Dindo showed that PPBS was superior to DJBL due to an excess risk level of 25% (RD: 0.25, CI: 0.01–0.49). Reintervention rates were more favourable in the PPBS group, without significant differences in risk (RD: −0.03, CI: −0.27 to 0.20). However, PPBS seemed more efficient regarding weight loss outcomes at 1-year follow-up according to raw data, while meta-analysis did not reveal any significant difference (odds ratio (OR): 1.08, CI: 0.74–1.59 for BMI changes). Conclusion Only limited conclusions can be made based on our findings. PPBS was superior to DJBL with regard to safety outcomes (GRADE IIB), which failed to support the authors’ hypothesis. Surgical procedures showed lower complication rates than the incidence of DJBL-related AEs, although it should be emphasized that the low number of PPBS-related mild to moderate complications reported could be the result of incomplete data recording from the analysed publications. Weight loss outcomes favoured bariatric surgery (GRADE IIB). As the DJBL is implanted into the upper gastrointestinal tract for 6 to 12 months, it seems a promising additional method in the inventory of metabolic interventions.
Összefoglaló. Az acut myeloid leukemia a csontvelői eredetű hemopoetikus őssejtek malignus klonális betegsége. A betegség lefolyása, különösen a nagy dózisú kemoterápiára és allogén csontvelő-transzplantációra alkalmatlan betegek számára, a legutóbbi időkig szinte kivétel nélkül fatális volt. Az idős és/vagy leromlott állapotú acut myeloid leukemiás betegek kezelésében óriási áttörést hozott a Bcl2- (B-cell lymphoma 2) inhibitor – venetoclax és a hypomethyláló azacitidin kombinációja. Ötvenéves nőbetegünkön a normál karyotípusú, nucleophosmin 1 mutációval járó acut myeloid leukemia diagnózisa előtt szeptikus állapotot okozó végbéltályog miatt tehermentesítő colostomaképzést végeztünk. A széles spektrumú kombinált antibiotikus kezelés mellett is súlyosan elesett, szeptikus állapotú betegen a nagy dózisú, kuratív indukciós kezelést nem tartottuk kivitelezhetőnek, ezért venetoclax–azacitidin kombinációt alkalmaztunk. A beteg az első ciklus alatt az antibiotikus, antimycoticus kezelés mellett masszív hemoszupportációra szorult. A második ciklus alatt lényeges szövődményt már nem észleltünk, a ciklus végén elvégzett csontvelővizsgálat pedig komplett hematológiai remissziót igazolt. A páciens önellátóvá vált, a végbéltályog jelentősen javult. Az új kezelési lehetőség mellett elért remisszió, a beteg javuló általános állapota korábban ismeretlen problémát vet fel. Egy 50 éves beteg jó prognózisú eltéréssel járó acut myeloid leukemiájának ellátása a nagy dózisú kemoterápiával elért első remisszióban nem igényel allogén csontvelő-transzplantációt. „Nem kuratív” kezeléssel elért remisszióban hogyan folytassuk a kezelést? Summary. Acute myeloid leukemia is a clonal malignancy of bone marrow haemopoietic stem cells. Until recently the outcome of the disease has been almost without exemption fatal, especially in cases ineligible for high dose induction chemotherapy and bone marrow transplantation. The Bcl-2 inhibitor venetoclax-azacitidine combination is a breakthrough therapy for the elderly and frail AML patient. Prior to the diagnosis of normal karyotype NPM 1 mutant AML of our 50-year-old female patient a colostomy had been performed due to anal abscess leading to sepsis. The septic patient being extremely frail in spite of wide spectrum antibiotic treatment was deemed ineligible for high dose curative induction treatment, hence venetoclax-azacitidine combined treatment was used. During cycle 1 the patient needed massive transfusion support beside concomitant antibiotic and antimycotic medication. On course of cycle 2 no major complications were detected, BM evaluation at the end of cycle confirmed complete haemotologic remission. The abscess significantly improved, the patient’s self-care capability was restored. The remission induced by this new option and the improvement of the performance status of the patient raised hitherto unasked questions. In case of a patient aged 50, a favourable prognosis AML in remission following high dose induction does not mandate HSCT as a next step. How shall we follow the course of treatment in remission elicited by a ‘non-curative’ option?
