Multiple jejunal diverticulitis with perforation in a patient with systemic lupus erythematosus: report of a case.

A 70-year-old man with systemic lupus erythematosus (SLE) was brought to our Emergency Department after the sudden onset of acute and severe abdominal pain. Physical examination revealed a tender and distended abdomen with guarding and rebound tenderness in the periumbilical region and the left upper quadrant. A plain abdominal X-ray taken with the patient upright showed air fluid levels with dilatation of several loops in the small bowel. As the examination could not rule out bowel ischemia, perforation, or obstruction, an emergency laparotomy was performed, which revealed multiple jejunal diverticulosis, one of which had perforated and adhered to the right colon, causing rotation. The diverticulosis segment was resected and an end-to-end anastomosis was done. The patient had an uneventful postoperative recovery without any complications. This is an unusual cause of peritonitis in a patient with SLE, and we could not find any evidence to suggest involvement of the underlying SLE in the jejunal diverticulosis and diverticulitis in this patient. Nevertheless, the involvement of SLE might be possible and further investigation is warranted.

Effects of molsidomine and lexipafant in hepatic ischaemia--reperfusion injury.

PURPOSE: The purpose of this study was to evaluate the effects of nitric oxide donor molsidomine and platelet-activating factor (PAF) antagonist lexipafant on the hepatic IR injury in rats. METHODS: Fifty male Sprague-Dawley rats (200-225 g) were divided into five groups each containing 10 rats; group SO: Sham operation group; group I: hepatic ischaemia group; group IR: ischaemia-reperfusion (IR); group M: IR plus pretreatment with molsidomine; group L: IR plus pretreatment with lexipafant. Hepatic ischaemia and reperfusion, each were applied for 45 min. Hepatic specimens were obtained to determine the tissue levels of malondialdehyde (MDA) and histological changes. Blood samples were obtained by cardiac puncture for determination of alanine transaminase (ALT), aspartate transaminase (AST) and lactic dehydrogenase (LDH). RESULTS: The liver damage scores of groups I, IR, M and L were significantly higher than that of group SO (P < 0.001). The liver damage scores of groups IR and M were significantly higher than that of group I (P = 0.009 and 0.0035, respectively). The liver damage scores of groups M and L were significantly lower than that of group IR (P < 0.001 for both M and L). Mean MDA levels of groups I and IR were significantly higher than those of group SO (P < 0.001). Administrations of molsidomine and lexipafant prior to ischaemia-reperfusion (IR) resulted in significant reduction of the MDA values (P < 0.001). A statistically significant (P < 0.001) decrease in the levels of AST, ALT and LDH was observed in groups M and L compared with group IR. CONCLUSION: In conclusion, these observations suggest that pre-treatment with nitric oxide donor molsidomine and PAF antagonist lexipafant before the reperfusion period may be useful in preventing hepatic reperfusion injury.

Diagnosis and surgical treatment of intrabiliary ruptured hydatid disease of the liver.

BACKGROUND AND OBJECTIVES: The major complication of hydatid disease of the liver is intrabiliary rupture of the cyst. The purpose of this study was to evaluate the outcome of patients with intrabiliary ruptured hydatid disease of the liver. METHOD: Using a standardised data collection instrument, case records of patients who were operated on for hydatid disease of the liver diagnosed between January 1990 and December 2001 at Dicle University Hospital (DUH) were searched and 192 patients who had been operated for hydatid disease of the liver were detected. Of these, 20 patients (16 females, 4 males) were retrospectively reviewed for intrabiliary ruptured hydatid disease of the liver. RESULTS: Intrabiliary ruptured hydatid disease of the liver was determined in 10.4% (N = 20) of the patients (N = 192) operated for hydatid disease of the liver. The average age of patients was 38.9 +/- 14.05 years (range 20 - 72 years). The duration of the symptoms was 3.4 +/- 2.13 years (range 1 - 8 years). The most frequent symptoms were right upper quadrant/epigastric pain, dyspepsia, jaundice and pruritus. Diagnosis of hydatid cyst was principally made using ultrasonography. Twelve cysts (60%) were located in the right lobe, 5 (25%) in the left lobe, and 3 (15%) in the right and left lobes. The size of the cysts was 12.6 +/- 5.79 cm (range 6 - 20 cm). The average diameter of the common bile duct (CBD) was 20.45 +/- 8.54 mm (range 10 - 40 mm). Dilated CBD in 16 patients (80%) and daughter cysts and debris in the CBD in 10 patients (50%) were found during operation. Partial cystectomy and capitonnage were performed in all patients. In addition, T-tube drainage in 17 patients, omentoplasty plus T-tube drainage in 2 patients and choledochoduodenostomy in 1 patient were carried out during operation. An internal opening of the biliary fistula was found and sutured in 12 patients (60%). Wound infections developed in 6 patients (30%), suppuration of the residual cavity in 4 patients, and wound dehiscence in 2 patients. Two patients (10%) died from sepsis-multiple organ failure and hepatic failure. The average period of hospitalisation was 28.75 +/- 19.1 days (range 10 - 103 days). CONCLUSIONS: If bile-stained cystic fluid and a dilated CBD is found in patients with hydatid disease of the liver, choledochal exploration should be performed during operation. T-tube drainage may be preferred in the management of intrabiliary ruptured hydatid disease because of low morbidity, the ability to decompress intrabiliary pressure, easier monitoring of the biliary drainage and smaller alteration of the anatomy.

Effectiveness of collagenase in the treatment of sacrococcygeal pilonidal sinus disease.

PURPOSE: Sacrococcygeal pilonidal sinus disease (SPSD) is a disease affecting young patients, which results in a long-term loss of productive power, and also tends to have high rates of morbidity since it has no ideal treatment. The main purpose of this study was to investigate the effectiveness of topical collagenase in the treatment of SPSD. METHODS: In the present study, 40 patients admitted to our department were separated into two groups. Excision and marsupialization with dressing by bacterial collagenase was performed in the first group, while the treatment was excision and marsupialization without dressing by bacterial collagenase in the second group. RESULTS: We determined that the healing in terms of the width and depth of the wound in the first week and in depth of wound in the second week was better in group 1 than in group 2 ( P = 0.040, P = 0.020, P = 0.048, respectively). The duration of wound healing was 21.9 +/- 1.3 days in group 1, and 28.1 +/- 1.3 days in group 2 ( P = 0.0001). The recurrence rate in the intergluteal area, which heals by granulation and has no hair follicles, tends to decrease when a partial closure is obtained. CONCLUSION: We therefore recommend an excision, marsupialization, and dressing with bacterial collagenase, in cases with noncomplicated SPSD.

Spontaneous liver hematoma and a hepatic rupture in HELLP syndrome: report of two cases.

Subcapsular liver hematomas and ruptures are unusual fatal complications of HELLP (hemolysis, elevated liver enzymes, and low platelets) syndrome (HS). We present two cases of a spontaneous rupture of subcapsular liver hematoma occurring in HS and review the literature on this subjects. One case demonstrated a secondary rupture of a subcapsulary liver hematoma due to HS in one patient and HS associated with preeclampsia in another. The defects were on the medial and lateral sectors of the left lobe in one patient and on the medial sector of the right lobe in the other patient. In case 1 deep mattress sutures and omentoplasty were performed, and in the other case a defective area was closed with an absorbable gelatin sponge with a hemostatic effect. In addition, the liver was compressed by abdominal towels. A high index of suspicion and immediate recognition are keys to proper diagnosis and management of affected patients. The multidisciplinary approach to the management of these patients led to a remarkable decrease in the mortality rates. Less aggressive treatment is preferable to aggressive intervention such as a hepatic resection in such patients with coagulopathy.

[Intestinal and peritoneal tuberculosis].

BACKGROUND: Abdominal tuberculosis (tbc) is still a medical problem in developing countries. Since it imitates many abdominal diseases, diagnosis can be easily missed unless the disease is suspected. METHODS: The aim of this study to evaluate the value of clinical, physical and laboratory findings and to discuss the diagnostic and therapeutic options in 121 patients with intestinal and peritoneal tbc. The diagnosis was made by histopathological examination of biopsy material and isolation of mycobacterium bacillus in cultures or smears of ascites fluid. RESULTS: The diagnosis was confirmed with laparotomy in 102, laparoscopy in 4, colonoscopy in 6, and percutaneous aspiration in 9 patients. There were intestinal tbc in 67 (55.3%) patients and peritoneal tbc in 54 (44.6%). Intestinal involvement was commonly located at ileocecal area. Anti tuberculous chemotherapy was started and avoided from extensive resection in surgical treatment. There were a total of 87 complications in 52 patients (42.9%) at the postoperative period. Wound infection was the most frequent complication. Overall mortality rate was 13.2%. The mortality rate in emergency operation was 20.5% while 3.4% in elective conditions. There were no morbidity and mortality in patients whose diagnosis were made by conservative procedures. CONCLUSIONS: Laparoscopic endoscopic and percutaneous aspiration procedures are useful for diagnosis in the selected cases of intestinal and peritoneal tbc. Laparotomy should be performed only when complication develops or diagnosis is uncertain. Extensive resection should be avoided in surgical treatment of intestinal tbc. Early diagnosis and treatment will decrease the complications that can be develop during the progress of the disease and consequently the mortality rates.

[The metabolic and hormonal effects of perioperative ibuprofen treatment on surgical stress].

BACKGROUND: Surgical stress induces hormonal and cytokine responses proportional to the extent of the injury. Perioperative administration of cyclo-oxygenase inhibitors reduces cytokine production and nitrogen losses. The objective of this study is to evaluate clinically the metabolic and hormonal effects of ibuprofen which is cyclo-oxygenase inhibitor on surgical stress. METHODS: A prospective clinic study was performed in 20 patients who undergone thyroidectomy. Patients were randomly divided two groups as ibuprofen group (n = 10) and control group (n = 10). In the ibuprofen group, pills containing ibuprofen (400 mg) were administered orally 12 and 2 hours before surgery, and every 8 hours until the third postoperative day. In the both groups, blood samples were collected 24 and 2 hours before surgery and 1, 4, 6, 24, 48, and 72 hours after skin incision for glucose, CRP, leukocytes, ACTH, cortisol determinations. RESULTS: When preoperative values were compared with postoperative values, surgical stress caused significantly changes on the all parameters in the both groups. The highest levels of ACTH and cortisol were at 1st and 6th hours respectively. In both groups, plasma cortisol levels remained elevated for 3 days, whereas plasma ACTH levels returned to the basal level at 1 day. In the ibuprofen group, the levels of ACTH and cortisol were significantly less than those of control group (p < 0.001 and p < 0.001). In the ibuprofen group glucose level (p < 0.001) and count leukocyte (p < 0.001) increased mildly. The level of CRP increased gradually after first day and were high until 3rd days (p < 0.01). In the ibuprofen group the fever increased smaller (p < 0.01). CONCLUSIONS: In conclusion, in perioperative period pretreatment with ibuprofen is able to reduce the neuroendocrine and humoral responses, but it can not completely suppress. Our present study suggests that ibuprofen may be useful in decreasing the surgical stress response in the serious patients.

The effects of glucose-insulin-potassium solution and BN 52021 in intestinal ischemia-reperfusion injury.

The objective of this study was to investigate effects of glucose-insulin-potassium (GIK) solution and BN 52021, a platelet-activating factor antagonist, on intestinal ischemia-reperfusion injury. Fifty male Sprague-Dawley rats (200-225 g) were divided into 5 groups each containing 10 rats; group SO, sham operation group; group I, mesenteric ischemia group (for 30 minutes); group R, ischemia plus reperfusion (for 60 minutes); group BR, ischemia-reperfusion plus BN 52021; group GR, ischemia-reperfusion plus GIK solution. Samples for malondialdehyde (MDA) and ileum (for mucosal injury score) were obtained. The mucosal injury scores of group R were significantly higher than those of group I (4 +/-0.20 and 3 +/-0.16, respectively, p<0.0001). The scores of groups BR and GR were significantly lower than those of group R (p<0.0001 and p<0.0001, respectively). When it was compared with the injuries in BR and GR groups, similar results were obtained in both groups (p=0.190). Mean MDA levels of group R were significantly higher than those of group I, BR and GR (131.33 +/-3.99 nmol/g, 93.74 +/-3.22 nmol/g, 104.81 +/-2.56 and 100.34 +/-5.30, respectively, p<0.0001). MDA levels of group BR and GR were significantly lower than those of group I (p<0.0001 and p=0.003, respectively). These observations suggest that treatment with GIK solution and BN 52021 before reperfusion and during reperfusion period may be useful in decreasing intestinal reperfusion injury.
