Hyperfunctioning parathyroid cysts: a case report.

Parathyroid cysts are infrequent lesions of which most are non-functional. They are often misdiagnosed as thyroid cysts. Pre-operative diagnosis and differentiation from thyroid cysts is generally difficult. We hereby report a case that was admitted to the emergency room and was diagnosed as hypercalcemic crisis. The mass found during the neck examination was thought to be a thyroid nodule. A right total and left subtotal thyroidectomy was performed. Palpable thyroid nodule was diagnosed as cystic parathyroid adenoma postoperatively. When a cystic lesion is found in the neck of a patient, a pararthyroid cyst should be considered.

Laparoscopic splenectomy for haematological diseases.

PURPOSE: To show the utility of laparoscopic splenectomy for hematologic diseases. PATIENTS AND METHODS: Ten patients with hematologic diseases who were operated between February 1997 and October 1998 were analysed retrospectively. TECHNIQUE: The operations were performed by four trocars, hilar vessels were divided by clips and bag was used for splenic retrival. RESULTS: All operations were completed successfully. No accessory spleens were found. Intraoperative complication, other than a bag tear in one operation did not occur. Postoperative complications occurred in two patients. The first one was a portal vein thrombosis and the second one was a peritonitis. All patients responded hematologically to the operation. CONCLUSION: With appropriate surgical technique and patient follow up, laparoscopic splenectomy is a safe, adventageous and efficaceus operation for hematologic diseases.

Diaphragmatic herniation after transhiatal esophagectomy.

Increasing experience with transhiatal esophagectomy (THE) has brought with it a good understanding of the advantages and disadvantages of the technique. As in our case, diaphragmatic hernias after THE may result from excess manipulation and extension of the hiatus during surgery. The varying nature of the clinical presentation may cause delay in diagnosis. We report our case and discuss how to diagnose and manage this complication under the sum of cases reported previously in English literature.

Portomesenteric gas due to intestinal obstruction: a case report.

A case of mesenteric vein gas as a nonfatal complication of intestinal obstruction is reported. A 48-year-old woman presented postoperatively signs and symptoms of acute abdomen on the eighth day following a gastric pull-up surgery due to an oesophageal carcinoma. The abdominal tomography findings revealed dilated jejunal segments and free gas in the superior mesenteric vein and end branches of the portal vein in the left hepatic lobe. The patient underwent a second laparotomy with a provisional diagnosis of intestinal ischaemia. Intraoperative gross appearance of the intestines revealed no ischaemic finding, the pathology was the dense adhesions between the jejunal segments and previous incision site. On the basis of these findings, the operation was ended with adhesiolysis. One month after the operation, the patient was well, there were no complications. As the authors, we think that the main reason for portomesenteric gas is mucosal destruction and that these case may be followed conservatively as long as intestinal ischaemia is excluded.

Traumatic diaphragmatic hernias: a report of 26 cases.

Traumatic diaphragmatic hernias, when diagnosed many years after the traumatic event, are observed in about 10% of diaphragmatic injuries. Due to coexisting injuries and the silent nature of diaphragmatic injuries, the diagnosis is easily missed or difficult. The medical records of 26 patients, who were treated for diaphragmatic hernias during the last 20 years, were analysed retrospectively. The patients were divided into acute phase and late-presenting groups, in whom emergency surgery and elective intervention were performed respectively. Chest radiography was diagnostic in 34.6% (n = 9) of patients. 92.3% of the hernias were on the left side, while the most common herniated organs were the stomach (31.8%) and the colon (27.2%). Coexisting injuries were recorded in 38.4% (n = 10) of the patients. Primary repair was predominantly used (92.3%). The hospitalisation period was longer in the late-presenting group (24.1 +/- 18.8 vs. 14.3 +/- 7.7 days). Two deaths occurred in the late-presenting group. Diaphragmatic hernia should be suspected in all blunt abdominal trauma patients. Prompt surgical repair is the treatment of choice in all traumatic diaphragmatic hernias.

Effects of CO2 insufflation and laparotomy on wound healing in mice.

BACKGROUND: The aim of the present study was to evaluate the effects of laparotomy and CO2 insufflation on wound healing in a murine incisional wound healing model. METHODS: Seventy-two male Swiss Albino mice were randomly allocated into three groups of control, laparotomy and CO2 insufflation. A transverse skin incision of 15 mm was made in the dorsum of each mouse, and four interrupted mattress sutures with 4.0 polypropylene thread were laid for wound closure. A median laparotomy was performed in the laparotomy group. CO2 insufflation was performed with an intra-abdominal pressure of 9 mmHg. The retained gas was evacuated from the abdominal cavity at the end of a 60-min period. Mice were killed on the 3rd, 7th and 15th postoperative days. The wound tensile strength and 5-hydroxyproline concentration in the wound tissue were measured. RESULTS: Tensile strength of the incised skin increased as the post-incision period progressed. There was no significant difference between the tensile strengths of the incised skin of control, laparotomy and CO2 insufflation groups throughout the observation period. The skin 5-hydroxyproline concentrations of all groups were not significantly different at the 3rd postoperative day. But laparotomy and CO2 insufflation groups had lower 5-hydroxyproline concentrations at the 7th and 15th postoperative days, when compared to controls (P < 0.02 for 7th and 15th days). CONCLUSION: CO2 insufflation and laparotomy reduce the 5-hydroxyproline concentration of the wound, suggesting a diminished wound healing capacity.

Melatonin modulates mesenteric blood flow and TNFalpha concentrations after lipopolysaccharide challenge.

OBJECTIVE: To investigate the effect of various doses of melatonin on reduction in mesenteric blood flow (MBF) and increase in tumour necrosis factor alpha (TNFalpha) concentration caused by injection of lipopolysaccharide (LPS). DESIGN: University Hospital, Turkey. SETTING: Open experimental study. ANIMALS: 59 Swiss albino mice. INTERVENTIONS: Animals were injected with melatonin solvent or 1, 10, 100, or 500 mg/kg melatonin. Ten minutes later control animals were injected with saline, and the experimental group with LPS. MAIN OUTCOME MEASURES: Mesenteric blood flow and serum TNFalpha concentration. RESULTS: In control animals, 100 and 500 mg/kg melatonin reduced MBF. LPS reduced MBF in solvent, 1, and 10 mg/kg melatonin groups. The concentration of TNFalpha was considerably increased in the mice given LPS. Melatonin reduced this response significantly. CONCLUSION: In high doses melatonin directly reduces MBF. It has no protective effect on the LPS-induced decrease in MBF. In lower doses it blocks, but at higher doses reduces, LPS-induced TNFalpha production.

An experimental study of the adhesive potential of different meshes.

OBJECTIVE: To assess the adhesive potential and incidence of incisional hernia with three meshes. DESIGN: Open experimental study. SETTING: Surgical Research Laboratory, Turkey. ANIMALS: 75 Wistar albino rats INTERVENTIONS: Abdominal walls were excised, and defects closed primarily or with polyglactin 910, polypropylene, or dura mater. Adhesions were graded and hydroxyproline concentrations measured on days 14 and 180. On day 180, the incidence of incisional hernia, and the grades of inflammation and fibrosis were also recorded. RESULTS: The polyglactin 910 group had a higher adhesion grading than the control and dura mater groups on day 14, whereas the polypropylene group had higher adhesion grading than controls. Both polypropylene and polyglactin 910 groups had significantly higher concentration of hydroxyproline than the control and dura mater groups. On day 180, the polypropylene group had a higher adhesion grading than the controls. There were no differences in hydroxyproline concentrations, incidence of hernias, or grading of fibrosis levels among the groups. CONCLUSION: Polyglactin 910 induced more fibrotic adhesions in the early postoperative period whereas polypropylene did in both the early and late postoperative periods.

The effects of G-CSF treatment and starvation on bacterial translocation in hemorrhagic shock.

BACKGROUND: Bacterial translocation is thought to be responsible for infectious complications after hemorrhagic shock. The aim of this study is to investigate the effects of granulocyte colony-stimulating factor (G-CSF) treatment on bacterial translocation in starved or fed animals subjected to hemorrhagic shock. MATERIALS AND METHODS: Fifty Wistar albino rats (200-275 g) were divided into six groups such as naive control (n = 7), G-CSF treatment (n = 7), hemorrhagic shock in starved rats (n = 9), hemorrhagic shock in fed rats (n = 9), G-CSF treatment 24 h before hemorrhagic shock in starved rats (n = 9), and G-CSF treatment 20 min after hemorrhagic shock in fed rats (n = 9). Hemorrhagic shock was induced by withdrawal of 2.1 ml/100 g blood via a carotid arterial cannulae placed under sodium pentobarbital anesthesia. Twenty-four hours later, mesenteric lymph nodes, liver, spleen, and peripheral blood samples were evaluated by using a quantitative microbiological technique and the numbers of colony-forming units were compared between groups. RESULTS: No bacteria was detected in samples from naive controls or G-CSF-treated unshocked rats. In animals subjected to hemorrhage, Escherichia coli was the predominant pathogen together with Streptococcus faecalis, Pseudomonas, and Lactobacillus species. In this model, starvation augmented the magnitude of bacterial translocation while G-CSF treatment has virtually abolished it. CONCLUSION: Under experimental conditions, preshock starvation increases gut-derived bacterial translocation and administration of G-CSF before or after hemorrhagic insult significantly reduces it.

A case of acute pancreatitis in a patient with systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is an auto-immune disease which can affect multiple organs. It may also involve the pancreas and in rare cases may cause acute pancreatitis. The etiology of acute pancreatitis in SLE is a matter of controversy. We present a case diagnosed with SLE that developed acute pancreatitis while being treated with corticosteroids. During the course of the disease, pancreatic pseudocysts developed and were treated by percutaneous drainage. There are few reports in the literature about the therapy of acute pancreatitis and percutaneous drainage of pseudocysts in SLE. We discuss the pathogenesis and therapy for acute pancreatitis in SLE patients.

Missed malignancies during laparoscopic cholecystectomy.

BACKGROUND/AIMS: Laparoscopic cholecystectomy is now the treatment of choice for symptomatic gallstone diseases. However, besides its great benefits, perhaps the most disappointing complication of this operation is missed malignancies. In this study, patients who had missed malignancies that were diagnosed shortly after laparoscopic cholecystectomy were studied. We aim to find out the cause of missed and delayed diagnosis. METHODOLOGY: Between 1991 and June 1997, 9 patients undergoing laparoscopic cholecystectomy, which had been performed elsewhere 2-9 months earlier, and having had missed malignancy were included in this study. A diagnostic survey was collected from the medical records, questionnaires, and a semiological analysis. All laboratory data and physical findings, before and after laparoscopic cholecystectomy, were recorded. Follow-up data were obtained through a telephone questionnaire. RESULTS: Of these 9 patients, 6 had colorectal carcinoma and 3 had pancreas carcinoma. All patients complained of recent atypical pain at the time of laparoscopic cholecystectomy, except for 1 patient who had no symptomatic regression. CONCLUSIONS: It is necessary to make a careful semiological, physical and laboratory analysis of patients with cholelithiasis before especially laparoscopic cholecystectomy. Elderly patients, atypical biliary pain and associated symptoms must draw attention to the possibility malignancy.

Perforation of acute calculous Meckel's diverticulitis: a rare cause of acute abdomen in elderly.

Complications of the Meckel's diverticula are well-known and defined. However, acute inflammation and perforation secondary to a calculus is a rare clinical presentation. A case of acute calculous Meckel's diverticulitis with perforation in a 58-year old man is presented and possible pathological conditions are discussed. Location of the perforation, apical microscopic focal ulcers, and ischaemic changes in the diverticulum remind the pathogenesis comparable to that of acute calculous cholecystitis. This case report with major complications related to Meckel's diverticulum strengthens the concept of prophylactic resection of Meckel's diverticulum in adults, incidentally discovered at laparotomy.

Surgical treatment of substernal goiter.

BACKGROUND: Substernal goiter differs from its cervical counterpart in regard to its clinical presentation, surgical management, pathological analysis and postoperative complication. METHODS: Retrospective analysis of 1320 thyroidectomies performed at the Hacettepe University Hospital between 1990 and 1997. RESULTS: 30 (2.3%) of 1320 thyroidectomies underwent operation for removal of substernal goiters in an 8-year period. The most common symptom was cervical mass (67%) and 33% of the patients were asymptomatic. Computerised tomography was the most accurate pre-operative test for detecting substernal extension. Substernal goiters were removed by collar incisions in 93% of the cases. The pathology was generally found to be benign (94%), but follicular carcinoma was present in two (6%) patients. There was no mortality and no complications were observed in 73% of the patients. CONCLUSIONS: The presence of substernal goiter is an indication for removal given the lack of any effective medical therapy, low surgical morbidity, risk of malignancy and acute obstructing symptoms.

Hydatid cyst of the spleen: treatment options.

Hydatidosis is a highly endemic parasitic disease caused by Echinococcus. The spleen is infrequently involved in hydatid disease. Splenectomy is the conventional treatment, but there are other treatment options as well. In this article, we reviewed the data of 14 patients with splenic hydatidosis operated on during the last 20 years. The spleen was involved in 2.5% of all abdominal hydatidosis cases during this period and was the only location of disease in 7 of the 14 patients. Partial cystectomy and omentopexy was performed on 2 patients, and splenectomy was performed on 12 patients. In 2 patients, percutaneous drainage was the initial choice of treatment but was not successful, and splenectomy was performed eventually. There was no mortality, and the morbidity rate was 28.6%. Although currently splenectomy is the conventional treatment, experience suggests that partial cystectomy and omentopexy should be the procedure of choice for the treatment of splenic hydatidosis.
