Complications of gynaecological laparoscopy--a retrospective analysis of 3572 cases from a single institute.

Three thousand, five hundred and seventy-two laparoscopic procedures were analysed retrospectively from a single institution between 1996 and 2003. Operations were classified into four groups as diagnostic laparoscopy (386, 10.8%), minor (1092, 30.5%), major (1866, 52.4%) and advanced (228, 6.5%) laparoscopic procedures. Overall, 67 (1.88%) complications occurred. The complication rates were 1.81%, 1.37%, 1.82% and 4.82% in the respective groups. One death (0.03%) occurred due to aortic injury during insertion of the principal intraumbilical trocar. Complications during insertion of the Verres needle, principal and accessory trocars were noted in 25 cases (38.2%) and were comparable among the four groups. Intraoperative complications occurred in 32 patients (47.8%) encountered mainly in the major and advanced groups. Overall, acute postoperative complications occurred in 10 (14.9%) patients. Despite advanced technology and experience, complications during the installation phase of laparoscopy remain a major cause of significant morbidity and most operative complications occurred in advanced operative procedures. Complications associated with all types of laparoscopic procedures should not be underestimated.     

Ginkgo biloba extract ameliorates ischemia reperfusion-induced renal injury in rats.

There is increasing evidence to suggest that reactive oxygen metabolites (ROMs) play a role in the pathogenesis of ischemia/reperfusion injury (I/R) in the kidney. This study was designed to determine the possible protective effect of Ginkgo biloba extract (EGb) on renal ischemia/reperfusion (I/R) injury. Wistar albino rats were unilaterally nephrectomized, and 15 days later they were subjected to 45 min of renal pedicle occlusion followed by 6 h of reperfusion. Ginkgo biloba extract (EGb) (50 mg kg(-1) day(-1)) or saline was administered twice, 15 min prior to ischemia and immediately before the reperfusion period. At the end of the treatment period, all rats were decapitated. Kidney samples were taken for histological examination or determination of the renal malondialdehyde (MDA) and glutathione (GSH) levels, myeloperoxidase (MPO) activity and collagen content. Production of reactive oxidants was monitored by chemiluminescence (CL) assay. Creatinine and urea concentrations in blood were measured for the evaluation of renal function. Tumor necrosis factor-alpha (TNF-alpha) and lactate dehydrogenase (LDH) were also assayed in serum samples. Ischemia/reperfusion caused a significant decrease in GSH level, which was accompanied with significant increases in MDA level, MPO activity and collagen content of kidney tissues. Similarly, serum BUN and creatinine levels, as well as LDH and TNF-alpha, were elevated in the I/R group as compared to control group. On the other hand, EGb treatment reversed all these biochemical indices, as well as histopathological alterations, which were induced by I/R. The findings imply that ROMs play a causal role in I/R-induced renal injury and EGb exerts renoprotective effects probably by the radical scavenging and antioxidant activities.     

Infection of Cranioplasty Seen Twenty Years Later

Cranioplasty is performed using autograft and allograft materials on patients to whom craniectomy was applied previously due to the facts that, this region is open to trauma and the scalp makes irritation and pressure onto the brain paranchyma causing brain atrophy and convulsions. Dramatical improvement of neurological deficits, control of convulsions and partial prevention of cerebral atrophy are achieved after these operations. One of the most important complications of cranioplasty is late infection. Here, we report a 43-year-old male patient admitted with the history of purulant discharge from the right temporal incission site for one year to whom cranioplasty had been performed with allograft material 20 days after craniectomy which had been performed in 1989. Allograft cranioplasty material was removed and cranioplasty was performed using new allograft material with the diagnosis of late cranioplasty infection.     

A new treatment modality for unilateral athelectasis: Recruitment maneuver with endobronchial blocker

Atelectasis is a commonly seen complication during the post-operative period in intensive care units. The treatment of atelectasis depends on the underlying cause. We aimed to share our experience on the treatment of right total atelectasis in our intensive care unit applied with the help of the endobronchial blocker.     

Effects of acute kidney injury on clinical outcomes in patients with upper gastrointestinal bleeding

Aim Upper gastrointestinal bleeding (UGIB) is a very frequently encountered condition that has a high morbidity and which increases treatment costs. Duration of hospital stay and mortality increases in patients with UGIB complicated by acute kidney injury (AKI). The aim of this study was to reveal risk factors in patients with UGIB developing AKI and to compare clinical outcomes and hospital costs between patients with UGIB developing AKI and those with UGIB not developing AKI.

Material and methods This retrospective study included 245 patients admitted to the emergency unit and the intensive care unit for internal diseases at Ankara Numune Education and Research Hospital, Turkey. Results The difference in mortality rates between the patients with AKI and those without AKI was significant (p?0.001). The mean duration of intensive care unit stay was 0.2?±?1.1 days in the patients without AKI (n?=?143) and 2.5?±?5.6 days in the patients with AKI. It was significantly higher in the patients with AKI (p?0.001). Hospital stay was significantly longer in the patients with AKI than those without AKI, and as severity of AKI increased, hospital stay became considerably longer (p?0.001). Hospital costs were significantly higher in the patients with AKI than those without AKI, and as severity of AKI increased, hospital costs considerably rose (p?0.001). Conclusion AKI is a condition that lengthens hospital stay, increases hospital costs and creates a burden on health care systems. Detect kidney injury earlier and administering an appropriate treatment can improve clinical outcomes in patients with UGIB developing AKI.     

Comparison of Ho:YAG laser and pneumatic lithotripsy in the treatment of impacted ureteral stones: An analysis of risk factors

The aim was to compare pneumatic and holmium:yttrium-aluminum-garnet laser in the treatment of impacted ureteral stones with different locations and to identify the risk factors for complications. Between March 2005 and November 2012, a total of 230 patients underwent ureteroscopic lithotripsy for impacted stones. Of the patients, 117 had pneumatic and 113 had laser lithotripsy for the fragmentation of the stones. Treatment outcomes based on evidence of being stone free were evaluated. Preoperative, operative, and postoperative follow-up findings were analyzed and compared. There was a difference between the two groups according to overall stone clearance rate (93.8% vs. 80.3%, p = 0.002). There was no statistically significant difference for distal location between the laser and pneumatic groups (96.8% vs. 91.7%, p = 0.288). For 10 patients with intrarenally migrated stones who were managed with flexible ureterorenoscopy in the same session, laser lithotripsy was more successful than pneumatic for proximal ureteral stone (94.4% vs. 67.9%, p = 0.007). The overall complication rate was 26.1%. There was no statistically significant difference between the two groups (29% vs. 23%, p = 0.296). Multivariate logistic regression analysis revealed that the proximal location was a statistically significant parameter for the occurrence of complications in both groups (p = 0.001 for PL, p = 0.004 for laser). The pneumatic and holmium:yttrium-aluminum-garnet laser lithotripsy are effective in the treatment of distal impacted stones. Both treatments with semirigid ureteroscopy are acceptable for proximal impacted ureteral stones, but holmium laser lithotripsy has an advantage of use with flexible ureteroscope for intrarenally migrated stone.     

Management of penile cancer patients during the COVID-19 pandemic: An eUROGEN accelerated Delphi consensus study

ObjectivesTo develop an international consensus on managing penile cancer patients during the COVID-19 acute waves. A major concern for patients with penile cancer during the coronavirus disease 2019 (COVID-19) pandemic is how the enforced safety measures will affect their disease management. Delays in diagnosis and treatment initiation may have an impact on the extent of the primary lesion as well as the cancer-specific survival because of the development and progression of inguinal lymph node metastases.Materials and methodsA review of the COVID-19 literature was conducted in conjunction with analysis of current international guidelines on the management of penile cancer. Results were presented to an international panel of experts on penile cancer and infection control by a virtual accelerated Delphi process using 4 survey rounds. Consensus opinion was defined as an agreement of ≥80%, which was used to reconfigure management pathways for penile cancer.ResultsLimited evidence is available for delaying penile cancer management. The consensus rate of agreement was 100% that penile cancer pathways should be reconfigured, and measures should be developed to prevent perioperative nosocomial transmission of COVID-19. The panel also reached a consensus on several statements aimed at reconfiguring the management of penile cancer patients during the COVID-19 pandemic.ConclusionsThe international consensus panel proposed a framework for the diagnostic and invasive therapeutic procedures for penile cancer within a low-risk environment for COVID-19.
