extremely rare complication of widespread retroperitoneal abscess originating from anorectal horseshoe abscess

Retroperitoneal and horseshoe abscesses are particularly important because of the anatomic characteristics and the clinical differences between treatment approaches. There are several challenges in treating perirectal and retroperitoneal abscess, the most important of which are partial recovery, high recurrence rates, and continence problems. A 65-yearold male patient underwent laparotomy at an external center with a diagnosis of ileus. Although no intraoperative pathology was detected, ileus persisted postoperatively, and the patient was referred to our clinic where he was diagnosed with a complicated horseshoe abscess, 9 cm in diameter and displaying retroperitoneal extension. Perirectal abscess drainage was performed, and the patient was discharged on the 5th day after the treatment. To the best of our knowledge, there have not been any previously reported cases of ileus caused by retroperitoneal abscess as a complication of horseshoe abscess. The case presented in this paper represents a rare complication, thereby contributing to the literature which remains to be explored

The effect of mesenchymal stem cell use on intra-abdominal adhesions in a rat model

PURPOSE: Intra-abdominal adhesions (IAA) are among the most frequently seen pathologies in general surgery practice with an increased morbidity and mortality. In the present study, we investigated the effect of locally applied mesenchymal stem cells (MSCs) on IAA. METHODS: Twenty-four Wistar Albino rats were used in the study. The rats were divided into three groups including: Sham, control, and MSCs group. On day 0, cecum was reached under anesthesia in all groups, except the Sham group. Scraping with a sponge was performed until petechial bleeding occurred. The control group received no treatment. In the stem cell group, MSCs were applied topically immediately after surgery on adhesions. The rats were sacrificed on day 10 and colon tissues and blood samples were collected for macroscopic, histopathological, and biochemical analysis. RESULTS: In our study, E-selectin, P-selectin, TNF-α and IL-1 levels were statistically significantly lower in the MSC group than the control group, while the sham group has the lowest levels. In both the macroscopic and histopathological analyses (Zühlke's scale), the least amount of adhesion was observed in the Sham group. In addition, although there was less adhesion in the MSC group than the control group, the difference did not reach statistical significance. CONCLUSION: Topical MSC application immediately after surgery suppresses the inflammatory process. However it was found to be ineffective in histopathological and macroscopic examinations performed on the 10th day.

Effectiveness of thymoquinone, zeolite, and platelet-rich plasma in model of corrosive oesophagitis induced in rats

PURPOSE: The effectiveness of platelet-rich plasma (PRP), thymoquinone, and zeolite in corrosive esophageal burns was investigated in a rat model. METHODS: Four groups were comprised as containing 10 rats in each group. For group I, oesophagitis was induced and no other procedure was performed (control group). For group II, oesophagitis was induced and thymoquinone was administered for 1 week via oral gavage once a day (thymoquinone group). For group III, oesophagitis was induced for 1 week via oral gavage once a day (PRP group). For group IV, oesophagitis was induced and zeolite was administered for 1 week via oral gavage once a day (zeolite group). On the 10th day, the rats were sacrificed under anaesthesia and venous blood sampling was performed from the vena portae. The oesophaguses were totally excised. Biochemically, interleukin (IL)-1B, IL-6, TNF-α, and MCP-1 were examined from venous blood. Inflammation score was evaluated histopathologically in oesophageal tissue that was collected. RESULTS: There was a statistically significant difference among groups in terms of IL-1, IL-6, MCP levels, compared to the control group; median IL-1, IL-6, MCP levels of thymoquinone, PRP, and zeolite groups were statistically significantly lower. There was a statistically significant difference among groups in terms of inflammation scores, compared to group I; median inflammation scores of groups II, III and IV were statistically significantly lower thymoquinone. CONCLUSION: PRP, and zeolite exhibited positive effect on recovery in oesophagitis by reducing inflammation in the involved segment.

Effect of ankaferd blood stopper in experimental peritoneal adhesion model

PURPOSE: Ankaferd Blood Stopper (ABS) is an herbal extract attained from 5 different plants. It has the therapeutic potential to be used for the management of external hemorrhage and controlling gastrointestinal bleedings. To date, the safety of ABS for intraperitoneal usage is not clear. In this study, we investigated the effectiveness and safety of using intraperitoneal ABS in an experimental peritoneal adhesion model. METHODS: Twenty-four male Wistar Albino rats were used in the study. The rats were randomly divided into 3 groups: saline, ABS, and control. On the 10th day, all rats were euthanized. The adhesions were evaluated by Nair's macroscopic adhesion classification, and pathologically evaluated with Zühlke's microscopic adhesion classification. RESULTS: macroscopic and microscopic comparison between the ABS and saline groups did not show any differences but both the ABS and saline groups were superior when compared to the control group. CONCLUSION: ABS was found equally effective with saline on the abdominal adhesions and to no effect on postoperative adhesion formation.
