Abstract
Epirubicin hydrochloride (EPI) is an anticancer drug widely used in the treatment of many solid tumors, including ovarian cancer. Because of its anatomical location, ovarian cancer shows symptoms when it is already in an advanced stage and is thus more difficult to treat. Epirubicin hydrochloride kills cancer cells effectively, but its dose escalation is limited by its severe toxicity. By encapsulating epirubicin in dextran-based nanoparticles (POLEPI), we expected to deliver higher and thus clinically more effective doses directly to tumors, where epirubicin would be released and retained longer in the tumor. The antitumor activity of POLEPI compared to EPI was first tested ex vivo in a series of ovarian cancer patient-derived tumor xenografts (PDX). The most promising PDX was then implanted orthotopically into immunocompromised mice, and tumor growth was monitored via magnetic resonance imaging (MRI). Although we succeeded in suppressing the growth of ovarian cancer derived from a patient, in a mouse model by 70% compared to 40% via EPI in 5 days after only one injection, we could not eliminate serious side effects, and the study was terminated prematurely for humane reasons.

Abstract
Obstetric anal sphincter injuries are the most common cause of fecal incontinence in women yet remain under-diagnosed. The aim of this study was to assess the suitability of impedance spectroscopy for diagnosing sphincter injuries arising during delivery. This was a prospective single-center study. 22 female patients were included: 10 with symptoms of sphincter dysfunction, in the early postpartum period, and 12 unaffected, in the distant period of more than 2 years after natural delivery. The presence, extent and severity of anal sphincters injury was assessed by measuring the sphincter parameters in physical examination, the degree of sphincter damage in endoanal ultrasound imaging and the sphincters function parameters in anorectal manometry. All measurements were used as references and compared with the outcomes from the impedance spectroscopy models. Impedance spectroscopy showed the highest precision (with mean accuracy of 83.9%) in relation to transanal ultrasonography. 74.1% of its results corresponded to the results of rectal physical examination and 76.7% - to those of anorectal manometry. The method showed the highest accuracy in the assessment of the sphincter's parameters, both anatomically and functionally. New impedance spectroscopy techniques hold promise for detecting obstetric anal sphincter injuries.

Abstract
Bariatric surgery consists in duodenal exclusion from the food passage in obese patients with coexistent type 2 diabetes. Nowadays bariatric surgery is considered the most effective method of glycemic index normalization and insulin resistance reduction. Recent results on obese and non-obese rats showed remission of type 2 diabetes symptoms within few days after the surgery. The aim of the present work was to analyze the mechanisms of neuro-hormonal regulation responsible for early normalization of metabolic syndrome after bariatric surgery. In present study the concentration of selected intestinal hormones and adipokines in blood plasma and gastrointestinal tissues were analyzed. Study was conducted on Wistar rats. Animals were divided into three groups (each n=6): control (SH) shame-operated rats; animals in which visceral fat tissue was extracted (LP); and rats in which Scopinaro bariatric surgery was performed (BPD). Immunochemistry analysis of blood plasma showed decrease of insulin concentration in BPD and LP and increase of polypeptide YY (PYY) in BPD group as compared to the control. In duodenal mucosa homogenates the tendency to reduce insulin in LP and BPD group, and increase PYY and visfatin in BPD group was observed. Histometry analysis showed reduction of mucosa thickness in excluded segments of gastrointestinal tract in BPD group as compared to the SH and LP. Concluding, model studies on rats allowed better understanding of mechanisms important for early normalization of glycemic index and insulin resistance reduction in rats.

Abstract
It is said that leaving intact the functional motor unit of the pylorus leads to better gastric emptying and reduces postoperative upper gut motility disturbances. However, despite obvious different surgical approach, both major pancreatoduodenectomies lead to substantial myoelectrical dysfunctions. The latter are not efficiently recognized. We compared Whipple and Longmire-Traverso procedures in terms of electromyography patterns of the upper jejunum musculature and the density of Cajal cells network. Twelve male weaned pigs underwent surgery first to implant bipolar electrodes and telemetry transmitters for continuous electromyography recordings and then, after 1 week recovery, to create Whipple (n=6) and Longmire-Traverso (n=6) pancreatoduodenectomies. The first myoelectric activity was already registered 1-2 hours after both operations. Time to first regular patterns of migrating myoelectrical complex activity was significantly longer in the Whipple than in the Longmire-Traverso group (68.2±12.9 versus 27.8±51 hours, p=0.002). However, the restored patterns were substantially disturbed in both groups. Namely, after Longmire-Traverso operation, migrating myoelectrical complex cycles were very often and significantly shorter versus control ones, with reverse migration in the area of anastomosis while after Whipple procedure migrating myoelectrical complex cycles were less frequent and of short duration, significantly shorter in comparison even with Longmire-Traverso group. Cajal cells network in the vicinity of anastomosis, and distally from it, presented greater destruction after the Whipple operation. In conclusion, the advantage of one of two major pancreatoduodenectomies in terms of myoelectrical activity correctness in upper gut has not been proved in the study.

Abstract
BACKGROUND The frequency of foreign body retention in the abdominal cavity ranges from 1 in 100 to 1 in 3000 surgeries performed. Worldwide literature describes only a few cases of the migration of misplaced surgical gauze into the colon. CASE REPORTS The first case is a 60-year-old patient following laparoscopic cholecystectomy, who excreted (on his own) a cotton sheet 30 × 65 cm after 26 weeks, which did not possess a radiological locator. The latter fact caused diagnostic difficulties in interpreting ultrasonography, CT-scans and abdominal X-rays. Colonoscopy after 4 months following the excretion of the sheet showed flat, stretched ulceration of the colonic wall near the hepatic turn. The second case is a 76-year-old who had undergone several abdominal surgeries, including a classical cholecystectomy and extirpation of the uterus along with related tissues, as a result of cancer and with subsequent radiotherapy. The reason for the last intervention was an occlusion, which required a resection due to abscesses inside the peritoneal cavity. Abdominal pain continued after the surgery. Uroscopy and abdominal X-rays were performed 3 months later, which confirmed the presence of foreign matter in the abdominal cavity. CONCLUSIONS Most foreign objects that have migrated into the colon will be excreted autonomously, which warrants a conservative assessment. Radiologically-tagged materials should be used, which will greatly ease identification in cases of suspected retention of surgical materials in the abdominal cavity.

Abstract
We designed a conscious pig model to investigate myoelectric activity and the number of interstitial cells of Cajal (ICC) in the proximal jejunum following the Roux-en-Y and 'uncut' Roux procedures in relation to clinical outcomes. Twelve male Polish White pigs (8 weeks old, 10-13 kg) underwent surgery under general anaesthesia first to implant bipolar electrodes and telemetry transmitters for continuous electromyography recordings and then, after 1 week recovery, to create Roux-en-Y (n = 6) and 'uncut' Roux loops (n = 6). Upper gut tissue specimens were studied for the expression of c-kit staining procedure to quantitatively identify the presence of interstitial cells of Cajal. The intestinal migrating motor complex was restored within 10.5 and 37 h in 'uncut' Roux and Roux-en-Y pigs, respectively (P < 0.05). During 2 weeks, the 'uncut' Roux piglets increased their body weight by 18.0%, whereas the Roux-en-Y piglets increased their body weight by only 7.3% (P < or = 0.05). Two weeks after surgery, the number of ICC located in the region of Auerbach's plexus was higher and adhesions in the abdominal cavity lower in the 'uncut' Roux group. In conclusion, in the pig model, preservation of smooth muscle and ICC network continuity in the proximal jejunum may play an important role in early postsurgical recovery.
