Minimally Invasive Treatment of Pilonidal Disease: Crystallized Phenol and Laser Depilation

Pilonidal disease has been treated surgically and by various other methods for many years. The most important problem associated with such treatment is recurrence, but cosmetic outcome is another important issue that cannot be ignored. Today, crystallized phenol is recognized as a treatment option associated with good medical and cosmetic outcomes. We hypothesized that the addition of laser depilation to crystallized phenol treatment of pilonidal disease might increase the rate of success, and this study aimed to determine if the hypothesis was true. Patients who were treated with crystallized phenol and 755-nm alexandrite laser depilation were retrospectively analyzed. In total, 42 (31 male and 11 female) patients were treated with crystallized phenol and alexandrite laser depilation and were followed up between January 2009 and January 2012. In all, 38 patients (90.5%) had chronic disease and 4 (9.5%) had recurrent disease. Among the patients, 26 (61.9%) recovered following 1 crystallized phenol treatment, and the remaining patients had complete remission following repeated treatment. Some patients needed multiple treatments, even up to 8 times. None of the patients had a recurrence during a mean 24 months (range, 6-30 months) of follow-up. Whatever method of treatment is used for pilonidal disease, hair cleaning positively affects treatment outcome. The present results support the hypothesis that the addition of laser depilation (which provides more permanent and effective depilation than other methods) to crystallized phenol treatment (a non-radical, minimally invasive method associated with very good cosmetic results) can increase the effectiveness of the treatment and also reduce the recurrence rate of the disease.

Immunological follow-up of hydatid cyst cases

Hydatid disease is caused by Echinococcus granulosus. In this study, we aimed to investigate the benefit of monitoring cases with hydatid cyst by means of immune components in patients in a long-term follow-up after surgery. Eighty-four preoperative and postoperative serum samples from 14 cases undergoing surgery for hydatid disease were evaluated in terms of immune parameters, such as total and specific IgE, IgG, IgM, IgA and complement. Total and specific IgE were determined by ELISA. Specific IgG levels were measured by indirect hemagglutination. Total IgG, IgM, IgA and complement (C3 and C4) were detected by nephelometry. Imaging studies were also carried out during the follow-up. In none of the patients hydatid cysts were detected during the follow-up. Total IgE levels in the sera of the patients decreased to normal six months after surgery. Although specific IgE against echinococcal antigens decreased one year after operation, levels were still significantly high. There were no changes in the levels of anti-Echinococcus IgG and total IgG in follow-up period. Additionally, other parameters, such as IgA, IgM, C3 and C4, were not affected.

Implementation of a scoring system for assessing difficult cholecystectomies in a single center

PurposeLaparoscopic cholecystectomy (LC) is the treatment of choice for symptomatic cholelithiasis, but sometimes conversion to open cholecystectomy (OC) is necessary. The difficulty of LC or the risk of conversion to OC can be predicted by assessing some preoperative variables. We evaluated the efficacy of the “risk score for conversion from laparoscopic to open cholecystectomy” (RSCLO), which was recently developed by Kama et al. (Am J Surg 2001; 181:520), in a single center.MethodsWe recorded the RSCLO values of 571 patients admitted to undergo LC in the Department of General Surgery, Firat University Hospital, between June 2001 and June 2004.ResultsThe mean RSCLO score of 19 patients who needed conversion to OC was significantly higher than that of the patients who underwent successful LC, at 16.2 (range, −9 to 41) vs −5.7 (range, −20 to 25) (P < 0.001). The RSCLO was well correlated with conversion to OC. The sensitivity and specificity rates for RSCLO determining the risk of conversion to OC were 100% and 96%, respectively, and its positive and negative predictive values were 43% and 100%, respectively.ConclusionWe think that RSCLO could be used to define the term “difficult LC” more accurately and assist in selecting the most appropriate operation.

The effect of preoperative nutritional supports on patients with gastrointestinal cancer: prospective randomized study.

BACKGROUND/AIMS Malnutrition adversely affects the postoperative outcome of patients with gastrointestinal cancer. Therefore, the malnourished cancer patients are supported by enteral or parenteral nutrition. In this study, we aimed to investigate the effects of preoperative nutritional supports on total antioxidant capacity (TAC) in malnourished patients with gastrointestinal (GI) cancers. METHODOLOGY Seventy-five malnourished patients with GI cancers and 25 patients with non-cancer surgical problems were included in the study. The dietary of cancer patients were supported with immune-enhancing enteral solution in group II or standard enteral solution in group III and with parenteral solution in group IV. Plasma TAC levels were measured prior and after nutritional support. Data were expressed as mmol Trolox eq./L. RESULTS The mean TAC levels of groups before treatment were 1.10±0.17, 0.92±0.19, 0.89±0.17 and 0.92±0.18, respectively. It was significantly higher in group I than others. The mean TAC levels of supported groups after treatment were 1.11±0.20, 1.08±0.21 and 1.09±0.27, respectively. Although there was a statistically significant increase in TAC after treatment in group II and III, it was not statistically significant in group IV. CONCLUSIONS It was concluded that preoperative nutritional support with standard or immune-enhancing enteral solutions significantly increased TAC levels of malnourished patients with GI cancers.

The Comparison of Inflammatory Responses and Clinical Results After Groin Hernia Repair Using Polypropylene or Polyester Meshes

The aim of this study was to compare the clinical results and the inflammatory responses against polypropylene and polyester meshes after groin hernia repair. Ninety patients with unilateral inguinal hernia randomly underwent Shouldice herniorrhaphy or Lichtenstein hernioplasty using polypropylene or polyester meshes. Venous blood samples were collected to evaluate serum interleukin-6 (IL-6) and C-reactive protein (CRP) levels. Postoperative acute and chronic pain and time to attain to normal activities were evaluated. IL-6 levels decreased to preoperative levels in all groups at 48th hour. CRP levels of mesh-implanted groups are significantly higher than preoperative level at 48th hour, while it reduced to preoperative level in Shouldice herniorrhaphy group. Patients treated with mesh repair had less postoperative acute pain and recovered more rapidly than those who underwent Shouldice herniorrhaphy. It was concluded that polypropylene and polyester meshes used in hernia repair caused similar inflammatory responses and that clinical results after groin hernia repair with these prostheses were not significantly different.

Effect of melatonin and misoprostol on bacterial translocation in portal hypertensive rats

Background and Aim:  Portal hypertension is the main complication of cirrhosis and it is responsible for its most common complications. Bacterial translocation increases the morbidity and mortality rates in patients with portal hypertension. We aimed to investigate the effects of melatonin and misoprostol on bacterial translocation induced by portal hypertension.

Nonspecific ulcerated jejunitis as an unusual complication of laparoscopic cholecystectomy: report of a case.

We describe herein the case of a 65-year-old man in whom a lower gastrointestinal hemorrhage developed a few days after he underwent an elective laparoscopic cholecystectomy. A laparotomy was performed on postoperative day 16 and a jejunal segment containing mucosal changes and oozing ulcers was resected. Pathologic examination of the specimen revealed “nonspecific ulcerated jejunitis.” There is no explanation for the etiopathogenesis of this pathology; however, we concluded that this clinical picture may be attributed to ischemia-reperfusion injury that occurred following an ischemic period caused by the pneumoperitoneum during laparoscopic surgery.

Effect of Levamisole on intestinal anastomoses in transfused guinea pigs

Abstract In this experimental study, the effects of an antihelminthic and immunostimulating agent (levamisole) on anastomosis recovery in transfused and normal guinea pigs were investigated. A total of 56 animals were divided into four groups of 14 each; an additional 10 were employed for blood transfusion (BT). Intestinal anastomoses were performed on all animals; the following postoperative treatments were administered: none (control group); BT; intra-abdominal (IA) levamisole; and BT + levamisole. After recording the mortality of each group, a relaparotomy was performed on one-half of the animals on the 3rd postoperative day and on the remaining half on the 7th postoperative day. Findings of IA sepsis, resistance of the anastomosis, bursting pressure, and hydroxyproline values were evaluated. Statistical comparison of the groups was accomplished by analysis of variance. In the transfused group an increase in sepsis was determined and the bursting pressure was significantly lower than in the control group. IA levamisole application following BT reduced the mortality by diminishing IA sepsis and anastomotic abscess formation and increased anastomotic pressure and recovery (P < 0.01). Histopathologic recovery in levamisole groups was better than in the group that received BT only. Levamisole application without BT resulted in equal mortality and morbidity to that of the control group. We conclude that clinical use of levamisole should be considered only in intestinal anastomoses in which BT is inevitable.

Effects of platelet rich plasma on fascial healing in rats with fecal peritonitis

PURPOSE To evaluate the effects of platelet rich plasma (PRP) on the healing of fascia wherein peritonitis has been created. METHODS Twenty eight Wistar Albino rats were divided into four groups. Only a primary fascial repair following laparotomy was performed on Group 1, a primary fascial repair performed and PRP treatment applied following laparotomy on Group 2, and a fecal peritonitis created following laparotomy and a primary fascial repair carried out on Group 3. A fecal peritonitis was created following laparotomy and primary fascial repair and PRP treatment on the fascia was carried out on Group 4. RESULTS TNF-α was found to be significantly lower in the control group (Group 1). It was detected at the highest level in the group in which fecal peritonitis was created and PRP applied (Group 4). TGF-β was determined as being significantly higher only in Group 4. Histopathologically, the differences between the groups in terms of cell infiltration and collagen deposition were not found to be significant. CONCLUSION When platelet rich plasma was given histologically and biochemicaly as wound healing parameters cellular infiltration, collagen accumulation, and tissue hydroxyiproline levels were not increased but neovascularization, fibroblast activation and TNF Alfa levels were increased and PRP accelerated wound healing.
