Single-incision laparoscopic cholecystectomy versus laparoscopic cholecystectomy: a prospective randomized study.

This prospective randomized study compared single-incision laparoscopic cholecystectomy (SILC) and laparoscopic cholecystectomy (LC) with respect to estimated blood loss, operative time, postoperative pain levels, and complications. Thirty-four study patients were divided into 2 groups: 17 patients underwent SILC and 17 underwent LC. Operative time was longer for SILC than for LC, and the difference was statistically significant (P<0.001). There was no statistically significant difference in the relationship of body mass index with operative time between SILC and LC (P=0.613, P=0.983, respectively). The 2 groups had no statistically significant differences with respect to visual analog scale scores, estimated blood loss, shoulder pain, or complications (P>0.05). SILC can be the treatment of choice for gallbladder disease. Although the surgeon’s first several attempts at SILC require a longer operative time compared with LC, there are no differences in hospital length of stay, blood loss, complication rates, or pain scores between SILC and LC.

D-Dimer in the Early Diagnosis of Acute Mesenteric Ischemia Secondary to Arterial Occlusion in Rats

Background: Early diagnosis of mesenteric ischemia can be life saving. The aim of this study is to investigate the time-dependent diagnostic value of plasma D-dimer and other ancillary laboratory evaluations such as creatine phosphokinase, lactic dehydrogenase, aspartate aminotransferase, alanine aminotransferase, amylase, and leukocyte count in an experimental superior mesenteric arterial occlusion (SMA-O) model in rats. Methods: Forty male Wistar-Albino rats were separated into 4 groups: 2-, 4-, 6-, and 12-hour SMA-O groups. After laparotomy, the SMA was identified and ligated for 2, 4, 6 and 12 h in the 4 respective study groups. Blood samples were taken for laboratory tests 2 h after laparotomy in the control group and at the end of the ischemic period in the study groups. Results: The longer the duration of mesenteric ischemia, the higher were the serum D-dimer levels in the study groups, and statistical significance was obtained at 2 h (p = 0.021). Sensitivity, positive predictive value, negative predictive value, and accuracy of the relation were 88.8, 88.8, 100 and 90%, respectively. Leukocyte count was significantly higher than controls after 12 h. No other laboratory parameter correlated positively with the duration of mesenteric ischemia. Conclusion: Serum D-dimer measurements may be a valuable diagnostic parameter in the early diagnosis of mesenteric ischemia.

Comparison of Laparoscopic and Open Surgery for Total Rectal Prolapse

PurposeTotal rectal prolapse is a devastating disorder causing constipation and anal incontinence. We compared open and laparoscopic surgical approaches in a limited series.MethodsThe subjects of this study were 23 patients who underwent laparoscopic procedures (LP group) and 17 patients who underwent open procedures (OP group) for rectal prolapse. We assessed the preoperative colonic transit time, postoperative pain scoring, pre- and postoperative anal functions, and changes in constipation and related symptoms.ResultsThe median operation time was 140.8 min for the LP group and 113.1 min for the OP group (P = 0.037). The median postoperative hospital stay was 4.8 days after the LPs and 9.6 days after the OPs (P = 0.001). Less analgesia was needed in the early postoperative period after the LPs (P = 0.007). While more than 70% improvement in continence was seen in the patients who underwent OPs, it was about 85% in those who underwent LPs. Improvement in constipation and related symptoms were similar in both groups. More than 30% of patients still suffered from hard stools and other symptoms of constipation. The colonic transit times were reduced in about 50% of patients who had suffered constipation in both groups. There was no incidence of recurrence in the median follow-up period.ConclusionAlthough transabdominal rectopexy has been performed conventionally for rectal prolapse for many years, laparoscopic rectopexy and laparoscopic resection rectopexy are associated with lower morbidity and less postoperative pain. We eliminated the total prolapse and cured incontinence in almost all patients, with a short hospital stay.

Missed injuries in military patients with major trauma : Original study

OBJECTIVE The incidence and subsequent outcomes of missed injuries and the primary factors contributing to each missed injury were analyzed. METHODS Records of 709 trauma patients were reviewed between December 2003 and December 2004. Demographic data were compared and analyzed for two patient groups: those with multiple injuries diagnosed in 24 hours and those with multiple injuries diagnosed in >24 hours. RESULTS Fifty-two missed injuries were determined in 34 (4.8%) patients. There were significant differences between the patients with and without delayed diagnoses, including the mean injury severity scores (23 vs. 16.9), morbidity, and mortality (p < 0.05 for all). Among 69 contributing factors identified, 28 (40.6%) were unavoidable and 41 (59.4%) were potentially avoidable. CONCLUSIONS Missed injuries could usually be encountered in the most seriously injured patients, particularly in those with altered levels of consciousness. Missed injuries were mostly avoidable and most were the result of inadequate clinical examination.

The survival effect of E-cadherin and catenins in colorectal carcinomas

Aim  The E‐cadherin/catenin complex plays an important role in epithelial tissue architecture. Decreased expression of cell adhesion molecules (E‐cadherin, α‐, β‐ and γ‐catenin) have been reported to correlate with invasive behaviour. The aim of this study was to investigate the relation between the expression of adhesion molecules and clinicopathological characteristics and survival in colorectal carcinoma.

Colonic volvulus associated with Chilaiditi's syndrome: report of a case.

Hepatodiaphragmatic interposition of the intestine, known as Chilaiditi’s syndrome, is a rare and often asymptomatic anomaly, typically found as an incidental radiographic sign. We report a case of Chilaiditi’s syndrome associated with transverse colon volvulus, predisposed by segmental agenesis of the right lobe of the liver. A 45-year-old man presented with a 2-day history of abdominal pain, nausea, vomiting, and constipation. Plain chest X-ray and abdominal computed tomography showed colonic interposition and segmental agenesis of the right lobe of the liver. Laparotomy revealed a clockwise volvulus of the transverse colon associated with interposition and incarceration of the colon through the space of the agenetic segment of the liver. The transverse colon, which was adherent to the agenetic space in the liver and diaphragm, was dissected away and repositioned, and the volvulus was reduced. To our knowledge, this is only the sixth reported case of a colonic volvulus associated with Chilaiditi’s syndrome and the first case associated with segmental agenesis of the right lobe of the liver.

Hospital Experience, Body Image, and Cosmesis After Laparoscopic or Open Splenectomy

Background Laparoscopic splenectomy (LS) is becoming the “gold standard” technique for splenectomy. The aim of this study was to evaluate the hospital experience, body image, and cosmesis after LS or open splenectomy (OS). Methods Patients who underwent LS or OS were invited to fill out questionnaires evaluating their hospital experience, body image, and cosmetic results. A total of 72 patients (34 LS and 38 OS) agreed to participate in the study. Results No significant difference was observed between the groups in terms of age, sex, body mass index, or indication for splenectomy. Mean spleen weight and postoperative complications were slightly higher (P>0.05) and the postoperative hospital stay was significantly longer (P<0.05) in the OS group compared with the LS group. Scores from the modified Body Image, Hospital Experience, and Photo Series Questionnaires were higher (favorable) in the LS group compared with the OS group (P<0.01, P<0.001, and P<0.001, respectively). Conclusions LS is the procedure of choice for most indications of splenectomy, which has comparable or better perioperative outcomes and complication rate as well as the advantages of better body image, cosmesis, and hospital experience compared with OS. Our results presenting improved outcomes with LS will contribute to the widespread application of laparoscopy for splenectomy.

A Rare Complication after Thyroidectomy: Perforation of the Oesophagus: a Case Report

Abstract Perforation of the cervical oesophagus after thyroidectomy is an exceptionally rare complication. Total thyroidectomies, particularly for recurrent cases might possess an increased risk. Although rare, it has high mortality and morbidity. A patient that developed oesophagus perforation after a total thyroidectomy in a peripheral hospital for recurrent nodular goitre was treated and followed-up in our clinic. This well-documented case is discussed in conjunction with the information presented in the literature.

Early outcomes of laparoscopic procedures performed on military personnel with total rectal prolapse and follow-up.

Total rectal prolapse is a disorder frequently associated with constipation and anal incontinence. The aim of this study was to evaluate the outcomes of the complications, pain management, hospital stay, constipation, and anal functions of the patients undergoing 2 types of laparoscopic surgical approaches. In this study, 33 patients underwent either laparoscopic rectopexy or hand-assisted laparoscopic resection rectopexy. Preoperative colonic transit time, defecation, postoperative pain scoring, pre-postoperative evaluation of the anal function, and the changes in constipation and relating symptoms were assessed. Postoperative evaluation had been performed at the sixth week and the twelfth month. Median operation time was 137 minutes for rectopexy and 230 minutes for resection rectopexy group. Median postoperative hospital stay was 3 days for patients with rectopexy and 7 days for patients with resection rectopexy. Patients needed painkillers in short postoperative period for pain management in both groups. Continence was improved in 11 of 13 patients (84.6%) in a year after laparoscopic surgery. In 15 patients (45.5%), preoperative constipation either remained in the same or became worse in 7 (21.1%) in a year after surgery. No patient developed recurrence in the median follow-up period, which was about 15 months. Laparoscopic rectopexy and resection rectopexy in the young aged patients working the Army are carried out with less morbidity rate. We eliminated the total prolapse and cure incontinence in almost all patients. In addition to constipation was reduced by laparoscopic surgical approaches in a short time hospitalization with short time painkiller need.

Is Removal of the Stent at the End of 2 Weeks Helpful to Reduce Infectous or Urologic Complications After Renal Transplantation

OBJECTIVE Ureteral stents are used to reduce urologic complications after renal transplantation. However, they predispose to infection. The optimal time to keep them in the urinary tract has not yet been defined. The aim of this study was to evaluate the effect of early removal at the end of 2 weeks on urinary tract infections and early urologic complications (within 3 months), such as ureteroneocyctostomy leakage as well as ureteral anastomosis stricture or obstruction. METHODS We retrospectively analyzed the medical records of 48 patients who underwent renal transplantation using a ureteral stent. The patients were divided into two groups according to the time of stent removal: at the end of 2 weeks (group A; n = 10) versus at a later time (group B; n = 38). RESULTS The urologic complication rate was 0% in group A and the urinary tract infection rate, 2%. The urologic complication rate was 0% in group B and the urinary tract infection rate, 35%. CONCLUSION Early removal of the stent at the end of 2 weeks after renal transplantation is decreased the rate of urinary tract infections.
