The effect of Allium sativum in experimental peritoneal adhesion model in rats.

PURPOSE: To evaluate the effect of garlic on formation of postoperative adhesions in rats. METHODS: Twenty-four Sprague dawley rats were divided into three groups. In Group 1 (sham), laparotomy was performed and stitched up. In Group 2 (control), after laparotomy was performed, punctate hemorrhage was induced by cecal abrasion in the cecum and 2 cc of saline was intraperitoneally administered to each rat. In Group 3 (experimental), after laparotomy was performed, punctate hemorrhage was induced by cecal abrasion in the cecum and each rat was intraperitoneally administered a sterile Allium sativum derivative. The rats in all groups were re-laparotomized on postoperative day 7; samples were obtained from the peritoneal tissue surrounding the cecum. RESULTS: In Group 3, there was a statistically significant difference in terms of inflammation, lymph node size, and free oxygen radicals; these parameters tended to increase. In terms of fibrosis evaluated using H&E and MT, there was no significant difference between groups 2 and 3. CONCLUSIONS: No positive outcomes indicating that Allium sativum reduces intra-abdominal adhesions were obtained. However, it caused severe inflammation in the tissue. Additionally, in immunohistochemical analyses conducted to detect oxidative stress, allium sativum increased the production of free oxygen radicals in the tissue.

Synchronous pancreas and liver resection during CRS ± HIPEC. Results of 35 consecutive patients.

AIM: To evaluate the results of synchronous pancreas and liver resection in patients with metastatic carcinoma accompanied by peritoneal carcinomatosis (PC) who underwent cytoreductive surgery (CRS)/hyperthermic intraperitoneal chemotherapy (HIPEC). MATERIAL AND METHODS: Overall, 35 patients with PC who underwent CRS/HIPEC at Umraniye Education and Research Hospital owing to different etiological causes were evaluated for operation procedure, age, sex, comorbid diseases, ASA score, systemic chemo/radiotherapy, duration of surgery, chemotherapy (CT) protocol applied in HIPEC, amount of bleeding, synchronous hepatobiliary resection interventions during operation and short/long-term mortality and morbidity. RESULTS: Fifteen patients were male and 20 were female. Mean age was 58.375 ± 13.02 (range, 27-85) years. CRS/HIPEC was performed in 12 patients (34.3%), whereas only CRS was performed in 23 (65.7%) patients. The lowest and highest perioperative bleeding amount was 50 cc and 2000 cc, respectively, and 6 (17.1%) patients had intraoperative bleeding of ≥1000 cc. Synchronous isolated pancreatic resection, hepatic + pancreatic resection and isolated liver resection was performed in 3 (8.6%), 5 (14.3%) and 27 (77.1%) patients treated with CRS/HIPEC. Two patients died within postoperative day 30, and the mortality rate was 5.7%. CONCLUSION: Hepatopancreatobiliary surgery is a difficult intervention and is associated with serious morbidities. Synchronisation of hepatopancreatobiliary surgery with CRS/HIPEC may be challenging for the surgeon and clinician. Here we emphasise that this combination can be performed safely by an experienced team with a multidisciplinary approach and good patient preparation.

The effect of pycnogenol on lymphatic nodes and adhesion during in a peritoneal adhesion model in rats.

PURPOSE: To investigate the effects of pycnogenol on peritoneal adhesions and additionally to investigate the immunohistochemical effects of free oxygen radicals and reactive lymph nodes detected in the adhesive tissue that was sampled surrounding the cecum on intra-abdominal adhesions. METHODS: Twenty-seven Wistar Albino rats were divided into three groups. In group 1 (sham), laparotomy was performed and stitched up. In group 2 (control), after laparotomy was performed, punctate hemorrhage was induced by cecal abrasion in the cecum and each rat was intraperitoneally administered 2 cc of saline. In group 3 (experimental), after laparotomy was performed, punctate hemorrhage was induced by cecal abrasion in the cecum and each rat was intraperitoneally administered a sterile Pycnogenol derivative. The rats in all groups were re-laparotomized on postoperative day 7; samples were obtained from the peritoneal tissue surrounding the cecum, and the rats were sacrificed. RESULTS: In group 3, there was a statistically significant difference in terms of inflammation, lymph node size, and free oxygen radicals; these parameters tended to increase. In terms of fibrosis evaluated using H&E and MT, there was no significant difference between groups 2 and 3. CONCLUSIONS: No positive outcomes indicating that pycnogenol reduces intra-abdominal adhesions were obtained. However, it caused severe inflammation in the tissue. Moreover, a significant increase in lymph node size was detected secondary to inflammation. Additionally, in immunohistochemical analyses conducted to detect oxidative stress, pycnogenol increased the production of free oxygen radicals in the tissue.
