RESUMEN
BACKGROUND: The incidence of diaphragmatic rupture is low; however, it may be life threatening. Normally caused by blunt trauma, some cases are reported after pulmonary infections with extensive coughing. Covid 19 causes pulmonary infections and pneumonia and has been associated with weakening of the diaphragm after prolonged ventilation. We present a patient who suffered from diaphragmatic rupture 2 months after recovering from a severe Covid 19 pneumonia. CASE: A 71 years old male patient presented with massive thoraco-abdominal pain and severe dyspnea. At the time of admission, the patient was diagnosed with rupture of the diaphragm and developed cardiogenic shock. Intraoperatively there was a 4 cm diameter large rupture of the diaphragm with enterothorax (transverse colon, stomach, spleen, parts of the jejunum). Avulsion of the mesenteric arteries made a segmental resection of the jejunum together with the spleen necessary. A jejuno-jejunostomy was performed and organs were replaced into the abdomen. The rupture of the diaphragm underwent primary closure with non-resorbable suture material. The patient has shown an uneventful post-operative course, fully recovered and was discharged on day 11 after surgery. CONCLUSION: Covid 19 is a disease that is known to have various effects on different organs. The diaphragm is only paid heed in case of dysfunction. Also in the setting of Covid 19 it is not known as prominent effector organ. Nevertheless its affection by coughing caused by Covid 19 can lead to life threatening complications.

INTRODUCTION: Right-sided and left-sided colorectal cancer (CRC) is known to differ in their molecular carcinogenic pathways. The prevalence of sarcopenia is known to worsen the outcome after hepatic resection. We sought to investigate the prevalence of sarcopenia and its prognostic application according to the primary CRC tumor site. METHODS: 355 patients (62% male) who underwent liver resection in our center were identified. Clinicopathologic characteristics and long-term outcomes were stratified by sarcopenia and primary tumor location (right-sided vs. left-sided). Tumors in the coecum, right sided and transverse colon were defined as right-sided, tumors in the left colon and rectum were defined as left-sided. Sarcopenia was assessed using the skeletal muscle index (SMI) with a measurement of the skeletal muscle area at the level L3. RESULTS: Patients who underwent right sided colectomy (n = 233, 65%) showed a higher prevalence of sarcopenia (35.2% vs. 23.9%, p = 0.03). These patients also had higher chances for postoperative complications with Clavien Dindo >3 (OR 1.21 CI95% 0.9-1.81, p = 0.05) and higher odds for mortality related to CRC (HR 1.2 CI95% 0.8-1.8, p = 0.03).On multivariable analysis prevalence of sarcopenia remained independently associated with worse overall survival and disease free survival (overall survival: HR 1.47 CI 95% 1.03-2.46, p = 0.03; HR 1.74 CI95% 1.09-3.4, p = 0.05 respectively). CONCLUSION: Sarcopenia is known to have a worse prognosis in patients with CRLM and CRC. Depending on the primary location sarcopenia has a variable effect on the outcome after liver resection.

OBJECTIVE: Low psoas muscle area is shown to be an indicator for worse postoperative outcome in patients undergoing vascular surgical. Additionally, it has been associated with longer durations of hospital stay in patients with cancer who undergo surgery and subsequently greater health care costs in Europe and the United States. We sought to evaluate this effect on hospital expenditure for patients undergoing vascular repair in a health care system with universal access. METHODS: Skeletal muscle mass was assessed on preoperative abdominal computed tomography scans of patients undergoing open aortic aneurysm repair in a retrospective fashion. The skeletal muscle index (SMI) was used to define low muscle mass. Health care costs were obtained for all patients and the relationship between a low SMI and higher costs was explored using linear regression and cross-sectional analysis. RESULTS: We included 156 patients (81.5% male) with a median age of 72 years undergoing elective surgery for infrarenal abdominal aortic aneurysm in this analysis. The median SMI for patients with low skeletal muscle mass was 53.21 cm2/kg and for patients without, 70.07 cm2/kg. Hospital duration of stay was 2 days longer in patients with low skeletal muscle mass as compared with patients with normal (14 days vs 11 days; P = .001), as was duration of intensive care stay (3 days vs 1 day; P = .01). The median overall hospital costs were 10,460 higher for patients with a low SMI as compared with patients with a normal physical constitution (53,739 [interquartile range, 45,007-62,471] vs 43,279 [interquartile range, 39,509-47,049]; P = .001). After confounder adjustment, a low SMI was associated with a 14.68% cost increase in overall hospital costs, for a cost increase of 6521. CONCLUSIONS: Low skeletal muscle mass is independently associated with higher hospital as well as intensive care costs in patients undergoing elective aortic aneurysm repair. Strategies to reduce this risk factor are warranted for these patients.

Incisional hernias (IHs) occur universally after orthotopic liver transplantation (OLT). This study aimed to investigate the effectiveness of porcine dermal collagen (PDC) as a closing aid in giant hernias after OLT in a prospective trial. If direct closure (DC) was not feasible due to the hernia size and abdominal wall constitution, a PDC mesh was implanted. All patients from the PDC and DC groups were followed prospectively for 24 months. IH recurrence rates served as the primary endpoint, and the development of infections and wound healing disorders served as the secondary endpoints. Recurrence rate was 21% (4/19) in DC patients and 12% (2/16) in PDC patients (P = 0.045). Implant site infections occurred in five of PDC and one of DC patients (P < 0.05). All of them were managed with antibiotics; two of the PDC patients required surgical drainage. Histological analysis of PDC mesh biopsies indicated good angiogenesis and integration of the PDC into the abdominal wall. PDC was effective in our study for incisional hernia repair, and our results compared favourably with those of patients in whom direct hernia closure was feasible.

OBJECTIVES: Malnutrition after heart transplantation (HTX) is related to graft sclerosis. The risk for malnutrition is often underestimated by conventional measurements. We aimed to compare these with objective assessors for malnutrition. METHODS: Recipients at least five yr after HTX were included. Body mass index (BMI), bioimpedance analysis (BIA), serum albumin (SA) and subjective global assessment (SGA) malnutrition, and concomitant diseases were assessed. The BIA was used as gold standard, and a phase difference (PD) <4 was defined as cutoff. RESULTS: Sixty recipients (47 male, 13 female) were analyzed. The prevalence of malnutrition was according to SGA 6.6% (4/60), BMI 8.3% (5/60), SA 31.6% (19/60), and BIA 48.3% (19/60). PD values did not correlate with BMI (r = 0.118; p = 0.079) or SGA (r = 0.289; p = 0.65), but with SA (r = 0.458; p = 0.001). Multivariate analysis yield SA and sCr as independent predictors for an existing malnutrition. ROC analysis showed an area under the receiver operating characteristic curve of 0.606 for SA as compared to 0.515 for the BMI and 0.698 for sCr in the prediction of existing malnutrition as defined by the PD. CONCLUSION: The BMI or the SGA did not show as much power in predicting an existing alimentary deficiency for heart recipients as did SA.

BACKGROUND AND AIMS: Post-operative hyperbilirubinaemia in patients undergoing liver resections is associated with high morbidity and mortality. Apart from different known factors responsible for the development of post-operative jaundice, little is known about the role of hepatobiliary transport systems in the pathogenesis of post-operative jaundice in humans after liver resection. METHODS: Two liver tissue samples were taken from 14 patients undergoing liver resection before and after Pringle manoeuvre. Patients were retrospectively divided into two groups according to post-operative bilirubin serum levels. The two groups were analysed comparing the results of hepatobiliary transporter [Na-taurocholate cotransporter (NTCP); multidrug resistance gene/phospholipid export pump(MDR3); bile salt export pump (BSEP); canalicular bile salt export pump (MRP2)], heat shock protein 70 (HSP70) expression as well as the results of routinely taken post-operative liver chemistry tests. RESULTS: Patients with low post-operative bilirubin had lower levels of NTCP, MDR3 and BSEP mRNA compared to those with high bilirubin after Pringle manoeuvre. HSP70 levels were significantly higher after ischaemia-reperfusion (IR) injury in both groups resulting in 4.5-fold median increase. Baseline median mRNA expression of all four transporters prior to Pringle manoeuvre tended to be lower in the low bilirubin group whereas expression of HSP70 was higher in the low bilirubin group compared to the high bilirubin group. DISCUSSION: Higher mRNA levels of HSP70 in the low bilirubin group could indicate a possible protective effect of high HSP70 levels against IR injury. Although the exact role of hepatobiliary transport systems in the development of post-operative hyper bilirubinemia is not yet completely understood, this study provides new insights into the molecular aspects of post-operative jaundice after liver surgery.

BACKGROUND: Increasing concern has been expressed worldwide on the problem of finding young doctors to enter a training programme in an operative speciality. MATERIALS AND METHODS: A survey comprising 22 questions on working conditions and job satisfaction was placed on the homepage of the Austrian Society of Surgery; 667 questionnaires were completed. RESULTS: The question whether surgery is threatened by a trainee shortage was answered with "yes" by 68%. Only 37% were satisfied with their working conditions. The majority (61%) specified documentation as making up between 20% and 40% of their workload, 22.5% estimated an even higher percentage. Only 17.7% were satisfied with payment. A clear majority works 60 to 80 h per week or more. Only 32.5% stated that they can leave the hospital in the morning after weekend duty; for night duty during the week, this percentage decreased to just 4.2%. As for surgical training, 33.3% were satisfied. Regular assessments between the trainees and their department heads were confirmed by only 34%. A clear majority (96%) is in favour of rotations in other hospitals during residency for the sake of broader experience. CONCLUSION: Working hour restrictions are essential, but not enough: Substantial improvements in the professional profile and in training are required.

BACKGROUND AND AIMS: Laparoscopic surgery has become the treatment of choice for cholecystectomy. Many studies showed that while this approach benefits the patient, the surgeon faces such distinct disadvantages as a poor ergonomic situation and limited degrees of freedom with limited motion as a consequence. Robots have the potential to overcome these problems. To evaluate the efficiency and feasibility of robotically assisted surgery (RAC), we designed a prospective study to compare it with standard laparoscopic cholecystectomy (SLC). MATERIALS AND METHODS: Between 2001 and 2003, 26 patients underwent SLC and 20 patients underwent RAC using the ZEUS system. The feasibility, safety, and possible advantages were evaluated. To assess the efficacy, the total time in the operating room was divided into preoperative, operative, and postoperative time frames. RESULTS: For RAC in comparison with SLC, the preoperative phase including equipment setup was significantly longer. In the intraoperative phase, the cut-closure time and camera and trocar insertion times were significantly longer. It is interesting to note that the net dissection time for the cystic artery, duct, and the gall bladder was not different from SLC. CONCLUSIONS: The study demonstrates the feasibility of robotically assisted cholecystectomy without system-specific morbidity. There is time loss in several phases of robotic surgery due to equipment setup and deinstallation and therefore, presents no benefit in using the robot in laparoscopic cholecystectomy.

BACKGROUND: The outcome of liver resections depends on complete removal of all detectable foci. Our aim was to determine the value of preoperative routine magnetic resonance imaging (MRI) for complete detection of hepatic lesions. METHODS: We compared 271 lesions seen on MRI in 182 patients to intraoperative findings (including intraoperative ultrasonography) and histology. RESULTS: The overall rate of lesions was 7% each for segments 2 and 3, as compared to 14-17% each for segments 5, 6, 7, and 8. Twenty-three additional lesions were found intraoperatively, two thirds of them in the left lobe (mean size: 1.4 cm; mean total number of lesions in those patients: 2.2). In segments 2 and 3, the relative frequency for intraoperative diagnosis of additional lesions was 17% and 20%, respectively. On the other hand, most of the 15 MRI lesions not verified intra- or postoperatively had been described in the right hepatic lobe (maximum: segment 6). CONCLUSION: MRI provided reliable preoperative lesion detection. Special attention should be paid to segments 2 and 3, which showed a lower total number of lesions but an elevated relative frequency of intraoperatively detected additional foci.

BACKGROUND/AIMS: The aim of our study was to determine if intraoperative ultrasonography is still necessary in the time of magnetic resonance imaging. METHODOLOGY: Our prospective study comprised 122 patients (82% with malignant tumors) undergoing partial hepatectomy with preoperative magnetic resonance imaging, done at the same institution using a standardized liver protocol as well as intraoperative ultrasonography performed in a systematic fashion. RESULTS: Seventeen additional malignant lesions in 16/122 patients (13.1%) were found intraoperatively [7 visible, 2 palpable, 8 (6.6%) diagnosed by intraoperative ultrasonography only; mean size: 1.5 cm; left:right lobe = 11:6]. This caused a change in surgical strategy in 14 patients (11.5%), including 6 patients (4.9%) with lesions seen on intraoperative ultrasonography only. The average total number of lesions in those patients was 3.4. Ten lesions (7 benign, 3 malignant) described on magnetic resonance imaging were not found on intraoperative ultrasonography, but no unnecessary operations resulted from this. In one patient additional micrometastases seen neither on magnetic resonance imaging nor on intraoperative ultrasonography were found histologically. CONCLUSIONS: Intraoperative ultrasonography is still worthwhile as it remains unsurpassed in the ultimate determination of the number of lesions, tumor extension and anatomical resolution. However, in the course of time its benefits may decrease further due to ongoing improvement of preoperative imaging.
