Purpose: Re-anastomosis after a Hartmann procedure is associated with a higher morbidity and mortality than other elective colorectal operations. The goal of this comparative study was to evaluate whether laparoscopic reversal is a justified operative approach, although the initial operation is most often an emergency laparotomy. Methods: A retrospective analysis was conducted on data collected on all 70 patients who underwent laparoscopic and open reversal of a Hartmann procedure at the Department of Surgery, University of Schleswig-Holstein, Campus Lübeck, between January 1999 and December 2011. Together with general demographic data, the analysis included the indication for the initial Hartmann procedure, time to reversal, intraoperative findings, the choice of operative method, operating time, postoperative pain control, return of normal bowel function, length of hospital stay, and peri- and postoperative morbidity and mortality. Results: In most patients, the Hartmann procedure was performed after a perforated sigmoid diverticulitis. We were not able to find any statistically significant differences with respect to gender, body mass index (BMI) and American Society of Anesthesiologists classification between the laparoscopic group (LG) ( N = 24 patients) and the open group (OG) ( N = 46). In the LG, patients were significantly younger ( p = 0.019). The median operating time was 210 min (75-245) in the LG, which was significantly longer than in the OG (166 min; 66-230). The statistical analysis of the duration of postoperative analgesic therapy (LG 7 days [-]; OG 12 days [-] ), return to normal diet (LG 3 days [-]; OG 4 days [-] ), return of normal bowel function (LG 3 days [-]; OG 4 days [-] ) and length of hospital stay (LOS) (LG 10 days [-]; OG 15 days [8-163]) detected significant differences in advantage for the LG. Unplanned return to theatre during index admission was only necessary in the OG ( N = 7, 15.2 %). With a median follow-up of 8 months (range 1-20), we observed a comparable number of minor complications in both groups but a significantly higher number of major complications in the OG ( N = 27, 58.7 %) ( p = 0.001). Conversion occurred in three cases (12.5 %). There was no mortality in either of the two groups. Conclusions: This study was able to demonstrate the feasibility of the laparoscopic approach. In terms of postoperative results it should be seen as equivalent to the open procedure. However, the laparoscopic approach requires profound surgical expertise. The indication should be made after a careful risk/benefit analysis for each individual patient. [ABSTRACT FROM AUTHOR]

The regular colonisation of the oesophagus with a Candida species can, after oesophageal perforation, result in a contamination of the mediastinum and the pleura with a Candida species. A patient cohort of 80 patients with oesophageal perforation between 1986 and 2010 was analysed retrospectively. The most common sources with positive results for Candida were mediastinal biopsies and broncho-alveolar secretions. Candida species were detected in 30% of the patients. The mortality rate was 41% in patients with positive microbiology results for Candida, whereas it was 23% in the remaining patient cohort. This difference did not reach statistical significance ( P = 0.124). Mortality associated with oesophageal perforation was attributed mainly to septic complications, such as mediastinitis and severe pneumonia. During the study period we observed a shift towards non-albicans species that were less susceptible or resistant to fluconazole. In selected patients with risk factors as immunosuppression, granulocytopenia and long-term intensive-care treatment together with the finding of Candida, an antimycotic therapy should be started. A surgical approach offers the possibility to obtain deep tissue biopsies. The antimycotic therapy should start with an echinocandin, as the resistance to fluconazole is growing and to cover non-albicans Candida species, too. [ABSTRACT FROM AUTHOR]

Aim The increasing experience within the area of laparoscopic procedures has paved the way for technically-complex procedures, such as distal pancreatectomy. In order to avoid complications associated with concomitant splenectomy, these procedures are increasingly performed with spleen preservation. A drawback is the low number of cases, which does not allow for an evidence-based comparison between laparoscopic and open procedures, and spleen-preserving and concomitant splenectomy procedures. Patients and Methods Between 2006 and 2010, all data for patients who underwent a laparoscopic distal pancreatectomy (LDP) at the Department of Surgery, University of Schleswig- Holstein, Luebeck, Germany, were collected are stored in a prospectively-maintained database. Patients with tumours in the pancreatic tail and body that did not exceed the level of the portal vein were included in this database. Results A total of 22 patients who underwent LDP could be included in the evaluation. Ten of those patients underwent a laparoscopic spleen-preserving distal pancreatectomy ( LSPDP), while the remaining 12 received an LDP with splenectomy ( LDPwS). The median operation time was 155 min (range: 98-253) for the LSPDP group, and 201 min (range: 60-310) for the LDPwS group ( P = 0.06). The median hospital stay was 8.5 days (range: 5-23) in the LSPDP group compared to 11 days (range: 4-41) in the LDPwS group ( P = 0.06). Pancreatic fistula occurred in two patients from each group. It caused an intraabdominal haemorrhage in one patient of the LSPDP group, which required re-laparoscopy. Two patients experienced subphrenic abscesses in the LDPwS group and were treated interventionally. Histological examination revealed six cystadenomas and five pseudocysts (maximum diameter: 7 cm) in the LDPwS group, and six neuroendocrine tumours (maximum diameter: 2 cm) in the LSPDP group. Conclusion LDP can be performed safely. The optic magnification provided by laparoscopy facilitates LSPDP, as dissection of the splenic vessels can be avoided. Although not significant, there was a trend towards reduced hospital stay and operating time for LSPDP. Oncologic outcomes and morbidity seem to not be inferior to open procedures. The size of the tumours and the peripancreatic, as well as paraneoplastic, tissue alterations determine the indication for splenectomy. [ABSTRACT FROM AUTHOR]

- Abstract
The aim of this study was to determine the pathological complete remission (pCR) rate, and its relationship to clinical outcome, in patients with adenocarcinoma of the stomach or oesophagogastric junction receiving preoperative 5-fluorouracil, leucovorin, oxaliplatin and docetaxel (FLOT) every 2 weeks. Data from these patients who received at least one cycle of preoperative FLOT followed by surgery were prospectively collected in three German centres. Outcome analyses were conducted and tumour samples were evaluated for pathological remission by a central pathologist. A total of 46 patients were included in this analysis. All patients had clinical T3- and/or N+-stages and 11 (23.9%) had distant metastases (M1). After a median of 4 (range 2-8) preoperative cycles, 8 of 46 patients (17.4%) achieved a pCR. The pCR rate was highest in tumours of intestinal type histology (30.8%) and in those located in the oesophagogastric junction (30.4%) and lowest in patients with diffuse/mixed type tumours (0%) or tumours located in the stomach (4.3%; p < 0.05 for both comparisons). Patients with pCR had 100% probability of overall and disease-free survival (DFS) during the observation period, which was significantly higher ( p = 0.037 and p = 0.009, respectively) than the survival probability in patients without pCR. In conclusion, treatment intensification using FLOT was associated with significant pCR rates in patients with oesophagogastric cancer. The distribution of pCR appeared to be significantly different according to histological type and location of the tumours. [ABSTRACT FROM AUTHOR]

- Abstract
Recently, expression profiling of breast carcinomas has revealed gene signatures that predict clinical outcome, and discerned prognostically relevant breast cancer subtypes. Measurement of the degree of genomic instability provides a very similar stratification of prognostic groups. We therefore hypothesized that these features are linked. We used gene expression profiling of 48 breast cancer specimens that profoundly differed in their degree of genomic instability and identified a set of 12 genes that defines the 2 groups. The biological and prognostic significance of this gene set was established through survival prediction in published datasets from patients with breast cancer. Of note, the gene expression signatures that define specific prognostic subtypes in other breast cancer datasets, such as luminal A and B, basal, normal-like, and ERBB2+, and prognostic signatures including MammaPrint® and Oncotype DX, predicted genomic instability in our samples. This remarkable congruence suggests a biological interdependence of poor-prognosis gene signatures, breast cancer subtypes, genomic instability, and clinical outcome. © 2008 Wiley-Liss, Inc.

Postoperative lymphoceles after renal transplantation appear in up to 18% of patients, followed by individual indisposition, pain or impaired graft function. Therapeutic options are percutaneous drainage, needle aspiration with sclerosing therapy, or internal surgical drainage by conventional or laparoscopic approach. The laparoscopic procedure offers short hospitalisation time and quick postoperative recovery. From 1993 to 1997, 16 patients underwent laparoscopic fenestration of a post-renal transplant lymphocele, and were presented in a retrospective analysis. Three patients have had previous abdominal surgery. Following preoperative ultrasound and CT scan, 16 patients underwent laparoscopic drainage after drainage and staining of the lymphocele with methylene blue. No conversion was necessary. Mean operation time was 42 min, no intraoperative complications were seen. Oral nutrition and immunosuppression were continued on the day of surgery, and patients were discharged between the 2nd and 5th (median hospital stay 3.3 d) day after surgery. No recurrence was evident in a follow-up time of 15–54 months (median 31.4 months). Renal function remained unchanged in all patients postoperatively. [ABSTRACT FROM AUTHOR]

- Abstract
Study Objective: To assess the pharmacokinetics of levofloxacin during continuous venovenous hemodiafiltration (CVVHDF) and continuous venovenous hemofiltration (CVVH)., Design: Nonrandomized pharmacokinetic evaluation., Setting: University surgical intensive care unit., Patients: Six critically ill patients., Intervention: Five patients received levofloxacin 500 mg/day and one patient received levofloxacin 125 mg/day All patients received continuous renal replacement therapy: CVVHDF on day 1 and CVVH on day 2, using an acrylonitrile hollow-fiber 0.9-m2 filter, constant blood flow rate of 90 ml/minute, substitution flow rate of 1 L/hour predilution, and dialysate flow rate of 1 L/hour (CVVHDF)., Measurements and Main Results: Serum, ultrafiltrate, and dialysate concentrations of levofloxacin were determined by high-performance liquid chromatography. Extracorporeal clearance was 26.05 +/- 4.66 ml/hour during CVVHDF and 15.71 +/- 2.73 ml/hour during CVVH (p<0.05). Elimination half-life was 28.08 +/- 4.5 hours and 45.9 +/- 17.7 hours, and distribution volume was 1.51 +/- 0.52 L/kg and 1.42 +/- 0.42 L/kg for CVVHDF and CVVH, respectively. Saturation was 0.76 +/- 0.13 for CVVHDF versus a sieving coefficient of 0.77 +/- 0.16 for CVVH., Conclusion: Marked extracorporeal elimination of levofloxacin occurs, requiring a dosage adjustment that can be calculated from the characteristics of CVVH and CVVHDF.
