RESUMO
BACKGROUND/AIM: Anterior resection is the gold standard surgery for high and middle rectal tumors. In cases where anterior resection is not feasible, the surgeon resorts to a non-restorative approach such as Hartmann's procedure or abdominoperineal resection. It is not well studied how Hartmann's procedure impacts quality of life. This cross-sectional cohort study compares the long-term quality of life after Hartmann's procedure with anterior resection and abdominoperineal resection. PATIENTS AND METHODS: Patients operated for high- or middle rectal cancer in the southern healthcare region of Sweden between 2007 and 2017 were identified and data were extracted from the Swedish Colorectal Cancer Registry. Further clinical variables were retrieved from medical charts. Quality of life was evaluated by SF-12-, EQ-5D-5L- and EORTC QLQ - CR29 questionnaires. RESULTS: Out of 521 patients included, 51 had undergone Hartmann's procedure, 381 anterior resection and 89 abdominoperineal resection. Hartmann patients were significantly older with more comorbidities. Median follow-up time was 104 months. There were no differences between groups in overall quality of life. Patients subjected to Hartmann's procedure reported inferior mobility, self-care, daily activities and reduced estimation of general health compared to those who had anterior resection. Abdominoperineal resection was associated with more impotence compared to Hartmann's procedure. CONCLUSION: Overall long-term QoL after Hartmann's procedure was comparable to anterior resection and abdominoperineal resection. In certain symptoms patients with Hartmann's procedure for rectal cancer scored worse compared to anterior resection, but patients were older and frailer making causal inference impossible.

AIM: There is ongoing controversy regarding the extent to which Hartmann's procedure (HP) should be used in rectal cancer treatment. This study was designed to investigate 30-day postoperative morbidity and mortality following HP, anterior resection (AR) and abdominoperineal resection (APR) for rectal cancer using a national registry. METHODS: All patients operated for rectal cancer, tumour height 5-15 cm, between the years 2010 and 2017, were identified through the Swedish colorectal cancer registry. RESULTS: A total of 8476 patients were included: 1210 (14%) undergoing HP, 5406 (64%) AR and 1860 (22%) APR. HP was associated with an increased risk of intra-abdominal infection (OR 1.7, CI 1.26-2.28, P = 0.0004) compared to AR and APR, while APR was related to an increased risk of overall complications (OR 1.18, CI 1.01-1.40, P = 0.040). No significant difference was observed in the rate of reoperations and readmissions between HP, AR and APR, and type of surgical procedure was not a risk factor for 30-day mortality. Findings from a subgroup analysis of patients with a tumour 5-7 cm from the anal verge revealed that HP was not associated with increased risk for complications or 30-day mortality. CONCLUSIONS: For patients where AR is not appropriate HP is a valid alternative with a favourable outcome. APR was associated with the highest overall 30-day complication rate.

PURPOSE: This study aimed to investigate patient-related factors predicting the selection of rectal cancer patients to Hartmann's procedure as well as to investigate how often, and on what grounds, anterior resection is intraoperatively changed to Hartmann's procedure. METHODS: Prospectively collected data from the Swedish Colorectal Cancer Registry regarding patients with rectal cancer operated upon from January 1 2007 to June 30 2017 in the county of Skåne were retrospectively reviewed. Data were expanded with further details from medical charts. A univariable analysis was performed to investigate variables associated with unplanned HP and significant variables included in a multivariable logistic regression analysis. RESULTS: Altogether, 1141 patients who underwent Hartmann's procedure (275 patients, 24%), anterior resection (491 patients, 43%), or abdominoperineal resection (375 patients, 33%) were included. Patients undergoing Hartmann's procedure were significantly older and had more frequently comorbidity. The decision to perform Hartmann's procedure was made preoperatively in 209 (76%) patients, most commonly because of a comorbidity (27%) or oncological reasons (25%). Patient preference was noted in 8% of cases. In 64 cases (23%), the decision was made intraoperatively, most often due to anastomotic difficulties (60%) and oncological reasons (22%). Anastomotic difficulties were most often reported due to technical difficulties, a low tumor or neoadjuvant radiotherapy. Male gender was a significant risk factor for undergoing unplanned Hartmann's procedure. CONCLUSIONS: The decision to perform Hartmann's procedure was frequently made intraoperatively. Hartmann's procedure should be considered and discussed preoperatively in old and frail patients, especially in the presence of mid-rectal cancer and/or male gender, since these factors increase the risk of intraoperative anastomotic difficulties.

Primary aortoduodenal fistula is a rare condition caused mainly by a bulging infra-renal aortic aneurysm with subsequent erosion of the duodenum and formation of a fistula. We present a patient who suffered from a herald upper gastrointestinal bleeding followed by circulo-respiratory collapse only hours after, due to bleeding from the fistula. The mortality is reported to be 100 %, requiring emergency EVAR or open aortic graft repair to control any further bleeding.

BACKGROUND: Results of previous studies regarding pelvic sepsis after Hartmann's procedure (HP) for rectal cancer have been inconsistent and few studies report the risk factors. This study aimed to investigate the incidence of pelvic sepsis after HP, identify risk factors and describe when as well as how pelvic sepsis was diagnosed and treated. METHODS: Data were collected from the Swedish Colorectal Cancer Registry on all patients undergoing HP for rectal cancer in the county of Skåne from 2007-2017. Patients diagnosed with pelvic sepsis were compared with patients without pelvic sepsis and risk factors for developing pelvic sepsis were analysed in a multivariable model. RESULTS: A total of 252 patients were included in the study, with 149 (59%) males, and a median age of 75 years (range 20-92). Altogether, 27 patients (11%) were diagnosed with pelvic sepsis. Risk factors for developing pelvic sepsis were neoadjuvant radiotherapy (OR 7.96, 95% CI 2.54-35.36) and BMI over 25 kg/m2 (OR 5.26, 95% CI 1.80-19.50). Median time from operation to diagnosis was 21 days (range 5-355) with 11 (40%) patients diagnosed beyond 30 days postoperatively. The majority of cases 19 (70%) were treated conservatively and none needed major surgery. CONCLUSION: Pelvic sepsis occurred in 11% of patients. Neoadjuvant radiotherapy and higher BMI were significant risk factors for developing pelvic sepsis. Forty percent of patients were diagnosed later than 30 days postoperatively and most patients were successfully treated conservatively. Our findings suggest that HP is a valid treatment option for rectal cancer when anastomosis is inappropriate, even in patients receiving neoadjuvant radiotherapy.

The major milestones in mouse placental development are well described, but our understanding is limited to how the placenta can adapt to damage or changes in the environment. By using stereology and expression of cell cycle markers, we found that the placenta grows under normal conditions not just by hyperplasia of trophoblast cells but also through extensive polyploidy and cell hypertrophy. In response to feeding a low protein diet to mothers prior to and during pregnancy, to mimic chronic malnutrition, we found that this normal program was altered and that it was influenced by the sex of the conceptus. Male fetuses showed intrauterine growth restriction (IUGR) by embryonic day (E) 18.5, just before term, whereas female fetuses showed IUGR as early as E16.5. This difference was correlated with differences in the size of the labyrinth layer of the placenta, the site of nutrient and gas exchange. Functional changes were implied based on up-regulation of nutrient transporter genes. The junctional zone was also affected, with a reduction in both glycogen trophoblast and spongiotrophoblast cells. These changes were associated with increased expression of Phlda2 and reduced expression of Egfr. Polyploidy, which results from endoreduplication, is a normal feature of trophoblast giant cells (TGC) but also spongiotrophoblast cells. Ploidy was increased in sinusoidal-TGCs and spongiotrophoblast cells, but not parietal-TGCs, in low protein placentas. These results indicate that the placenta undergoes a range of changes in development and function in response to poor maternal diet, many of which we interpret are aimed at mitigating the impacts on fetal and maternal health.

PURPOSE: Hartmann's procedure is a well-established alternative in colorectal surgery when a primary anastomosis is contraindicated. However, the rectal remnant may cause complications. This study was designed to investigate the occurrence of pelvic sepsis after Hartmann's procedure and identify possible risk factors. METHODS: All patients who underwent Hartmann's procedure between 2005 and 2012 were identified by the in-hospital registry. Information about pelvic sepsis and potential preoperative, perioperative, and postoperative risk factors was obtained by review of the medical records. RESULTS: 172 patients were identified (97 females); they were aged 74 ± 11 years. Surgery was performed due to cancer (49%) or diverticulitis (35%) and other benign disease (16%). Rectal transection was carried out anywhere between the pelvic floor and the promontory. Pelvic sepsis developed in 6.4% (11/172) of patients. Pelvic sepsis was associated with preoperative radiotherapy (p = 0.03) and Hinchey grade III and IV (p = 0.02) in those patients who underwent Hartmann's procedure for diverticular disease. CONCLUSION: Hartmann's procedure is a safe operation when an anastomosis is contraindicated since the incidence of pelvic sepsis is low. Preoperative radiotherapy and Hinchey grade III and IV may be risk factors for the development of pelvic sepsis.
RESUMO
Objective Using centralized registries in Iceland, the aim of this study was to prospectively investigate multiple risk factors for renal cell carcinoma (RCC), including occupational history. Materials and methods From the Reykjavik study database, 18,840 men and women born in the period 1907-1935 were linked with a population-based registry containing all RCCs diagnosed in Iceland from 1971 to 2005 (n = 910). From this cross-reference, altogether 225 cases were identified. A prospective analysis of the risk factors for RCC was performed using Cox regression analysis, from the time of entry into the Reykjavik study to the diagnosis of RCC, death or end of follow-up, with a median follow-up time of 25 years. The hazard ratio (HR) was then calculated for multiple risk factors including occupational history. Results Male gender [HR 1.65, 95% confidence interval (CI) 1.14-2.38], body mass index (BMI) over 25â kg/m² (HR 1.41, 95% CI 1.06-1.88) and age (HR 1.04, 95% CI 1.03-1.07) increased the risk of RCC, as did severe hypertension (>160/100â mmHg) (HR 1.46, 95% CI 1.05-2.03) and history of kidney disease (HR 1.55, 95% CI 1.11-2.16); however, smoking and type 2 diabetes were not significantly associated with the disease. The risk of RCC was significantly increased in painters (HR 2.97, 95% CI 1.31-6.74), aircraft mechanics (HR 4.51, 95% CI 1.11-18.28) and shipbuilders (HR 2.03, 95% CI 1.06-3.84). Conclusions Together with male gender, advanced age, hypertension, BMI over 25â kg/m² and history of kidney disease, the risk of RCC was significantly increased in painters, aircraft mechanics and shipbuilders, suggesting a link to occupational exposure.

Thymomas are usually benign tumors and are most often found in the anterior mediastinum. We report a rare case of a giant tumor in the right hemithorax that originated in the thymus. The tumor was 15x8 cm and histology revealed a type AB thymoma. The tumor was removed and the patient is doing well and is without symptoms two years after the operation. Key words: Thymoma, abdominal pain, giant tumor, mediastinum.

OBJECTIVE: The aim of this retrospective study was to compare kidney function in a population-based cohort of renal cell carcinoma (RCC) patients after partial (PN) or radical nephrectomy (RN). MATERIAL AND METHODS: Forty-four consecutive RCC patients who had undergone PN in Iceland between 2000 and 2010 were compared with 44 controls matched for tumour, node, metastasis (TNM) stage who had undergone RN during the same period. Estimated glomerular filtration rate (eGFR) and survival were calculated, and predictors of chronic kidney disease (CKD) were evaluated with multivariate analysis. RESULTS: In 16 cases (36%), PN was performed for imperative reasons (single kidney, decreased kidney function or bilateral kidney tumours) but 28 patients had a normal contralateral kidney. The groups were similar regarding preoperative eGFR, median follow-up and TNM stage, but age and American Society of Anesthesiologists (ASA) score were significantly higher in the RN group. Six months after surgery, eGFR was significantly higher in the PN group. By multivariate analysis, RN contributed negatively to eGFR 6 months after surgery (-12.6 ml/1.73 m², p < 0.001) and increased the risk of new-onset CKD (odds ratio = 3.07, 95% confidence interval 1.03-9.79, p = 0.04), compared to PN. At median follow-up of 44 months, no patients in either group had a recurrence of RCC. The 5-year overall survival (Kaplan-Meier) was 100% and 65% in the PN and RN groups, respectively (log-rank test, p < 0.001). CONCLUSION: eGFR was significantly lower after RN, and these patients were three times more likely to develop new-onset CKD. These findings suggest that PN successfully preserves kidney function compared to RN, with good oncological outcome and survival.

OBJECTIVE: The incidence of renal cell carcinoma (RCC) is rising in part due to small tumors (≤4cm) detected incidentally with abdominal imaging. Survival for small RCCs has been regarded as favorable and guidelines recommend partial rather than total nephrecteomy. We studied the frequency of synchronous metastasis in patients with small RCCs in Iceland. MATERIALS AND METHODS: A retrospective study on 257 patients with RCC ≤4cm out of 1102 RCC patients diagnosed in Iceland 1971-2010. Patients with metastasis were compared to those with localized disease. Hospital charts were reviewed and histology, TNM-stage and disease-specific survival compared between groups. RESULTS: The proportion of small tumors increased from 9% in 1971-1980 to 33% in 2001-2010 (p<0,001) and incidental detection increased from 14% to 39% during the same period. Out of the 257 patients with small RCCs, 25 (10%) had synchronous metastases, most frequently in lungs or bones. Patients with metastases were on average 1.9 years older, their tumors were 0.2 cm larger and more often located in the right kidney, their hemoglobin was lower and nuclear grade and T-stage higher. Histology was similar in both groups. Five-year survival of patients with and without metastases was 7 vs. 94%, respectively (p<0.001). CONCLUSIONS: One out of ten patients with small RCC has synchronous metastases at diagnosis. This is higher than in most previous reports that usually include surgical patients only. Patients with metastases are significantly older, more often symptomatic, their tumor are larger and their prognosis worse. Our results indicate that small RCC is a potentially systemic disease at diagnosis that has to be taken seriously.

The objective of this study was to re-examine histologically and restage thymic epithelial tumours during a 25-year period and to correlate clinical and follow-up data. We utilized centralized registries in Iceland to establish a true nationwide incidence rate, previously unreported. A retrospective whole population study was carried out by including all patients diagnosed with a thymic epithelial tumour in Iceland between 1 January 1984 and 30 April 2010. Medical records were reviewed and presenting symptoms, diagnostic procedures and surgical outcome tabulated. The histology of all cases was reclassified according to the 2004 World Health Organization classification (A-TC). The Masaoka system was used for tumour staging. Median follow-up was 67 months. A total of 19 patients were identified, 11 men (58%) and 8 women, with mean age at presentation of 63 years (31-87 years). The age-standardized incidence rate (ASR) was 0.3 and 0.2/100 000/year for men and women, respectively. Types B2 (n = 5) and A (n = 5) were the most common histological subtypes. Half of the patients had local symptoms, and eight were diagnosed incidentally. Of 19 patients, 11 underwent resection of the tumour through median sternotomy. Five-year overall survival was 53%. All four patients with thymic carcinoma (TC) died of disease within 2 years of diagnosis. For the other 15 patients, no recurrences were reported. Thymic tumours are rare in Iceland with an ASR (w) of 0.28 per 100 000 a year. To our knowledge, these are the first nationwide ASR (w) figures reported. The prognosis for most thymic epithelial cell tumours is excellent. However, TCs have a dismal long-term survival.
