An intraoperative serum parathormone level study in patients with chronic renal failure that underwent subtotal parathyroidectomy What extent of decrease is sufficient at which moment?

AIM: The aim of this study is to determine when to perform intraoperative parathormone (ioPTH) measurement and what extent of decrease in intraoperative serum PTH concentrations indicate success in the operations performed on patients with SHPT associated with chronic renal failure. MATERIAL AND METHODS: 50 consecutive patients who underwent subtotal parathyroidectomy between January 2012 and January 2019 were retrospectively included in this study. Patients were grouped according to persistent hyper parathyroidism (Group1, n:6) and curative surgery (Group 2, n:44). Preoperative serum PTH, calcium, phosphorus and ALP concentrations, intraoperative serum PTH concentrations; and serum PTH, calcium, phosphorus and ALP concentrations of 24th hour after surgery were included to the study. Intraoperatively, 20 minutes after parathyroid gland removal, blood was drawn for PTH assay. The changes in PTH levels between preoperative and intraoperative serum samples were calculated in percentage (ioPTH%) and postoperative 6th month serum PTH and ALP concentrations were included in the study. RESULTS: No significant differences were found by gender, BMI, elapsed period of dialysis treatment and preoperative laboratory values between Group 1 and Group 2. The meanage of Group 1 was 35 years which is lower than Group 2. With the second group, the mean decrease in PTH levels between intraoperative and preoperative serum samples (ioPTH%) was about 90%, which was higher than Group 1. CONCLUSIONS: In conclusion, we believe that, to encounter fewer persistent SHPT cases, it is essential that surgeons monitor ioPTH concentration 20 minutes after gland removal and confirm a decrease of 90% or more in ioPTH concentration. And we should not forget that young patients may tend to develop persistent SHPT.

The impact of the COVID-19 pandemic on emergency general surgery: a retrospective study.

BACKGROUND: The COVID-19 pandemic has affected healthcare systems worldwide. The effect of the pandemic on emergency general surgery patients remains unknown. OBJECTIVE: To reveal the effects of the COVID-19 pandemic on mortality and morbidity among emergency general surgery cases. DESIGN AND SETTING: Data on patients who were admitted to the emergency department of a tertiary hospital in Samsun, Turkey, and had consultations at the general surgery clinic were analyzed retrospectively. METHODS: Our study included comparative analysis on two groups of patients who received emergency general surgery consultations in our hospital: during the COVID-19 pandemic period (Group 2); and on the same dates one year previously (Group 1). RESULTS: There were 195 patients in Group 1 and 132 in Group 2 (P < 0.001). While 113 (58%) of the patients in Group 1 were women, only 58 (44%) were women in Group 2 (P = 0.013). Considering all types of diagnosis, there was no significant difference between the two groups (P = 0.261). The rates of abscess and delayed abdominal emergency diseases were higher in Group 2: one case (0.5%) versus ten cases (8%); P < 0.001. The morbidity rate was higher in Group 2 than in Group 1: three cases (1.5%) versus nine cases (7%); P = 0.016. CONCLUSIONS: The COVID-19 pandemic has decreased the number of unnecessary nonemergency admissions to the emergency department, but has not delayed patients' urgent consultations. The pandemic has led surgeons to deal with more complicated cases and greater numbers of complications.

Comparision of Hem-o-lok polymeric clip and tri-staple in laparoscopic splenectomy.

AIM: This study aimed to compare the hem-o-lok polymeric clip (HC) and tri-staple (TS) methods used in dividing the splenic hilum in terms of results, and to reveal their superiority to each other. MATERIAL AND METHODS: Medical records of patients undergoing elective laparoscopic splenectomy at the Ondokuz Mayis University Faculty of Medicine General Surgery Clinic between March 2011 and March 2020 were retrospectively analyzed. Forty-two laparoscopic splenectomy cases performed using hem-o-lok polymeric clip (HC) or tri-staple (TS) were included in this study. Demographic features, primary diagnoses, splenic size, intraoperative data and postoperative complications, as well as the clip and stapler prices used in the surgery were analyzed. RESULTS: The mean operative time was significantly longer for HC group than TS group (116.7 min vs. 87.6 min, p<0.05). The mean cost of surgical instruments used to divide the splenic hilum was significantly lower for HC group than TS group (34.1 usd vs. 165.4 usd, p<0.05). There was no postoperative mortality, with a morbidity rate 6 (26.1%) for TS group and 4 (21.1%) for HC group (p>0.05). No significant difference existed in the complication rates. CONCLUSIONS: In the HC group, the operation time was longer, but the surgical cost was significantly lower. There was no significant difference when comparing other perioperative results. Although both techniques can be applied safely, we would like to emphasize that hemostasis is the most important factor for good results.

Significance of hemogram on diagnosis of acute appendicitis during pregnancy.

BACKGROUND: Acute appendicitis (AA) is the most common emergency surgical condition during pregnancy after obstetric and gynecological pathologies. Urgent and accurate diagnosis of AA in pregnant patients reduces maternal and fetal morbidity/mortality rates. This study evaluated the significance of hemogram to diagnose AA during pregnancy. METHODS: Forty-seven pregnant patients operated for AA in the Ordu or Ondokuz Mayis University Medical School Hospitals between January 2007 and December 2017 were compared with 47 healthy pregnant women in terms of hemogram parameters, including the white blood cell (WBC) count, neutrophil count, lymphocyte count, platelet count, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), mean platelet volume (MPV), and red cell distribution width (RDW) values. The operated group was evaluated based on post-operative pathologic results and subclassified into appendicitis positive (Group A) and appendicitis negative (Group B) groups. The subgroups were compared to the control group. RESULTS: The WBC and neutrophil count and mean NLR and PLR values were significantly higher in Group A compared to Group B and the control group (p<0.001). The mean lymphocyte count was significantly lower in Group A compared to other groups (p<0.001). The MPV and RDW values and mean platelet count showed no significant difference between groups (p>0.05). When cutoff values for WBC, neutrophil count, NLR, PLR, and lymphocyte counts were set to >10300, >7950, >5.50, >155.2, and ≤1330, respectively, the sensitivity rates were 72.5%, 80%, 90%, 77.5% and 85%, whereas specificity rates were 72.3%, 79.7%, 89.4%, 74.5%, and 82.5%, respectively. CONCLUSION: When comparing pregnant women diagnosed with AA to patients operated for suspected AA and healthy pregnant women, the WBC and neutrophil count and NLR and PLR values were found to be significantly higher, whereas lymphocyte counts were lower. In addition to medical history, physical examination and imaging techniques, hemogram parameters should be considered to diagnose AA in pregnant women.

Serum human epididymis protein 4 levels in colorectal cancer patients.

Tumour markers are widely used for the diagnosis, staging and monitoring of colorectal cancer (CRC) patients in clinical practice. Carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) are the most frequently used biomarkers in CRC patients. A number of studies have recently investigated the presence of human epididymis protein 4 (HE4) overexpression in certain cancer types. Its significance in ovarian and endometrial cancer has been well-demonstrated. The aim of the present study was to evaluate the significance of serum HE4 levels in CRC patients. A total of 46 newly diagnosed CRC patients and 36 age- and gender-matched healthy subjects were included in the study. The concentrations of CEA and CA19-9 were also determined and compared according to HE4 levels. HE4 positivity was determined in 13 of the 46 cases (28.3%) in the CRC group, but no HE4-positive subjects were identified in the control group (0%; P=0.009). The area under the receiver operating characteristic curve for HE4 positivity was 0.641 (95% CI: 0.523-0.760). HE4 was statistically significantly positive in patients with stage III-IV disease and in those with high CA 19-9 levels (all P<0.01). To the best of our knowledge, this is the first study to investigate HE4 expression in CRC patients, and the findings suggest that it may be a useful biomarker, particularly in stage III-IV patients.

Factors affecting the conversion to open surgery during laparoscopic cholecystectomy in patients with cholelithiasis undergoing ERCP due to choledocholithiasis.

BACKGROUND: The rate of conversion to open surgery is high in laparoscopic cholecystectomy (LC) after Endoscopic Retrograde Cholangiopancreotocography (ERCP). The present study aimed to evaluate the risk factors associated with the conversion to open cholecystectomy and minimize the rate of conversion to open surgery. METHODS: A total of 157 patients admitted to the Ondokuz Mayis University Medical Faculty Hospital due to cholelithiasis and choledocholithiasis between January 2002 and December 2012, and they receiving laparoscopic cholecystectomy were included in the study. The patients were analyzed retrospectively. The predictive factors for conversion to open cholecystectomy were evaluated. Patients were compared to each other in terms of time passing from ERCP to operation, number of ERCPs, stent usage, stone extraction and complications that occurred while waiting for the operation. Patients were separated into three groups according to the time passing from ERCP to laparoscopic cholecystectomy, as follows; group I (short time intervals: 7 days or less): 53 patients, group II (intermediate time intervals: 8-42 days): 70 patients and group III (long time intervals: 43 days and more): 34 patients. RESULTS: Of the 157 patients, 57 were male and 100 were female. The mean age was 54.5 (range: 19-87) years. Of these 157 patients who received laparoscopic cholecystectomy following ERCP, 22 (14%) underwent open surgery. The conversion to open cholecystectomy was distributed in groups, as follows: seven (13.2%) patients in group I, eight (11.4%) patients in group II and seven (20.6%) patients in group III. When the rate of conversion to open surgery was compared between groups, there was no statistically significant difference (p=0.406). The laparoscopic operations were converted to open surgery in 15 (11.3%) of the 133 patients who underwent single ERCP, and in seven (29.2%) of the 24 patients who underwent two or more ERCPs before surgery (p=0.048). The number of ERCPs was determined to be the most important factor that affects the conversion to open surgery in laparoscopic cholecystectomies following ERCP. The removal of stones from the common bile duct, stent placement in the common bile duct, and existence of biliary complications during waiting time from ERCP to LC had no effect on the conversion to open surgery (p=0.454, p=0.058, and p=0.465, respectively). CONCLUSIONS: The results of this study reveal that the timing of LC following ERCP, removal of stones from the common bile duct, stent placement in the common bile duct and the existence of biliary complications during the waiting period have no effect on the rate of conversion to open surgery. The number of ERCPs is the only factor that affects the conversion to open surgery in LC following ERCP.

A First Report of Synchronous Intracapsular and Extracapsular Hepatic Adenoma.

Although the gallbladder is the most common site of ectopic liver, it has been reported in many other organs, such as kidney, adrenal glands, pancreas, omentum, stomach, esophagus, mediastinum, lungs, and heart. Hepatocytes in an ectopic liver behave like normal hepatocytes; furthermore, they can be associated with the same pathological findings as those in the main liver. Ectopic liver in the gallbladder can undergo fatty change, hemosiderosis, cholestasis, cirrhosis, hemangioma, focal nodular hyperplasia, adenoma, and even carcinogenesis. The incidence of extracapsular hepatic adenoma is not known, but only two cases have been reported. Here, we provide the first case report of synchronous multiple intracapsular and extracapsular hepatic adenomas. A 60-year-old woman with multiple hepatic adenomas and one 7 × 5 × 5 cm ectopic hepatic adenoma attached to the gallbladder fundus complicated with abdominal pain is presented.

Portomesenteric venous gas does not always mean intestinal necrosis: report of a case.

Portomesenteric venous gas is a rare condition most commonly caused by mesenteric ischaemia. Mesenteric ischemia, can be life-threatining and requires immediate surgical intervention with a poor prognosis. During the laparotomy, intestinal necrosis and perforation are most common findings although some patients reveal no surgical pathology. In this report we present a case of portomesenteric venous gas which is secondary to acute intramural intestinal haematoma.
