Diagnostic yield of whole-body 18F-FDG PET/CT in patients with suspected cardiac sarcoidosis

BackgroundWhole-body F-18 FDG PET has been included in the 2014 Heart Rhythm Society guidelines for cardiac sarcoidosis evaluation to identify alternate sites of biopsy prior to endomyocardial biopsy. The purpose of this study was to evaluate the diagnostic yield of whole-body F-18 FDG PET/CT. MethodsAll adult patients with suspected cardiac sarcoidosis undergoing same-day cardiac F-18 FDG PET/CT and whole-body F-18 FDG PET/CT between 10/1/2016 and 6/14/2021 to assess potential biopsy sites were retrospectively identified. Clinical indications, findings, recommendations, and outcomes were assessed. ResultsEighty-eight patients were included. Extracardiac PET findings suggestive of sarcoidosis were present in 30 patients (34%), 27 of which had thoracic findings (90%). Sarcoidosis was diagnosed in 11% of patients. Only 1% (1/88) was diagnosed by extrathoracic biopsy of a whole-body PET finding. Incidental findings were common (31%), resulting in 11 additional tests or interventions. Recommendations from extrathoracic findings affected treatment in one case: a drainage catheter placement into an unsuspected pelvic abscess. ConclusionAddition of whole-body F-18 FDG PET/CT to cardiac F-18 FDG PET/CT for the identification of extrathoracic sites of biopsy in patients with suspected cardiac sarcoidosis has marginal diagnostic yield but commonly results in incidental findings that rarely affect patient outcome.

How to manage a ureteral injury after anterior lumbar spine interbody fusion surgery

BackgroundAnterior lumbosacral interbody fusion (ALIF) surgery is a predominant approach used in various indications such as treating discogenic back pain, spondylolisthesis, degenerative lumbar scoliosis, intervertebral foraminal stenosis, or spondylolysis. In comparison with posterior conventional approach, ALIF surgery has several advantages: direct access to the spine without muscle dissection, reduced blood loss, decreased postoperative pain, and improved fusion rates. Rare complications following ALIF surgery need to be reported, therefore the authors present an uncommon case of a ureteral injury diagnosed early after surgery and its management. Management of a urinomaHerein, we present a case of a 35-year-old man who presented with abnormal abdominal pains 4 days after ALIF surgery. He was diagnosed with a distal left iatrogenic ureteral fistula on a contrast enhanced CT. After the initial endoscopic approach with double J stent and urinary catheter drainage insertion had failed, the injury was finally treated with ureterovesical reimplantation. At the last follow-up, the patient did well without any clinical or biological urinary sequelae after this grade IIIb complication on the Clavien Dindo Scale. ConclusionAlthough ureteral lesions during ALIF surgery are extremely uncommon, surgeons must be cautious when dissecting the retroperitoneal area. A methodical identification of the ureter might guarantee the security of each surgery, especially for patients who have undergone previous abdominal interventions.

THE EFFECT OF SUBCUTANEOUS TUNNELING ON EXTERNAL LUMBAR DRAINAGE COMPLICATIONS

Introduction
 Patients with a lumbar catheter become prone to infection due to the outflow of CSF. This research aimed to investigate how tunneled lumbar drainage affected infection in patients undergoing lumbar drainage.
 Materials and Methods
 This study was conducted on patients with lumbar drainage who were hospitalized for various clinical reasons. Subcutaneous drain length was measured by post-procedural lumbar tomography. The length of the lumbar drainage catheter, the duration of lumbar drainage, fever monitoring, CSF leakage, biochemical blood tests, the length of hospitalization, infection were recorded.
 Results
 This study comprised a total of 93 cases with external lumbar drainage. 51 (54.8%) of the 93 cases were inserted using the classic technique, 42 (45.2%) were inserted using the tunneled technique. The rate of CSF leakage was decreased using the tunneling approach (p = 0.003). A significant correlation was established between CSF leakage around the drain and subcutaneous drain length. CSF culture was negative in 78.8% of patients with subcutaneous drain lengths between 0 cm and 3 cm, and 100% of patients with subcutaneous drain lengths of 5 cm or more. Seven days or less was the cutoff value for negative CSF culture.
 Conclusion
 External lumbar draining can lead to issues such as infection and CSF leakage. The tunneling procedure is straight forward, affordable, and successfully prevents these complications.

Preventing inadvertent drain removal using a novel catheter securement device

Percutaneous drains have provided a minimally invasive way to treat a wide range of disorders from abscess drainage to enteral feeding solutions to treating hydronephrosis. These drains suffer from a high rate of dislodgement of up to 30% resulting in emergency room visits, repeat hospitalizations, and catheter repositioning/replacement procedures, which incur significant morbidity and mortality. Using ex vivo and in vivo models, a force body diagram was utilized to determine the forces experienced by a drainage catheter during dislodgement events, and the individual components which contribute to drainage catheter securement were empirically collected. Prototypes of a skin level catheter securement and valved quick release system were then developed. The system was inspired by capstans used in boating for increasing friction of a line around a central spool and quick release mechanisms used in electronics such as the Apple MagSafe computer charger. The device was tested in a porcine suprapubic model, which demonstrated the effectiveness of the device to prevent drain dislodgement. The prototype demonstrated that the miniaturized versions of technologies used in boating and electronics industries were able to meet the needs of preventing dislodgement of patient drainage catheters.

Trocar puncture with modified sump drainage for duodenal stump fistula after radical gastrectomy for gastric cancer: A retrospective controlled study

Duodenal stump fistula (DSF) is a serious complication of radical gastrectomy for gastric cancer. Herein, we illustrated an innovative choice for treating duodenal stump fistulas by placing a modified sump drainage through trocar puncture into the DSF-related abscess (DSF-abscess) cavity. We retrospectively analyzed 974 consecutive patients who underwent gastrectomy for gastric cancer between 2011 and 2021. Of these patients, 34 who developed postoperative duodenal stump fistulas postoperatively were enrolled into our study, and their clinical data were retrospectively assessed. From January 2011 to December 2017, 15 patients received conventional treatments (percutaneous catheter drainage, PCD group) known as the traditional percutaneous method, and 19 patients from January 2018 to December 2021 received new treatments (Troca's SD group) consisting of conventional therapies and placement of a modified sump drainage through trocar puncture into DSF-abscess cavity. The demographics, clinical characteristics and treatment outcomes were compared between two groups. Compared with the PCD group, the rates of postoperative complications, duodenostomy creation, subsequent surgery, fistula healing rates of the DSF, and length of postoperative hospital stay were significantly decreased in the Troca SD group. However, there was no significant difference in the abscess recurrence rate and mortality rates. Trocar puncture with a modified sump drainage is an safe, effective, and technically feasible treatment for duodenal stump fistula after radical gastrectomy for gastric cancer. This novel technique should be further investigated using large-scale RCT research.

Percutaneous drainage and combined praziquantel-albendazole therapy: a novel approach for the treatment of simple echinococcal liver cysts.

Cystic echinococcosis (CE) is a worldwide helminthic zoonosis causing serious disease in humans. The WHO Informal Working Group on Echinococcosis recommends a stage-specific treatment approach of hepatic CE that facilitates the decision on what therapy option is most appropriate. Percutaneous aspiration, instillation of a scolicide, e.g., ethanol or hypertonic saline, and subsequent re-aspiration (PAIR) have been advocated for treating medium-size unilocular WHO-stage CE1 cysts. PAIR can pose a risk of toxic cholangitis because of spillage of ethanol in the case of a cysto-biliary fistula or of life-threatening hypernatriaemia when hypertonic saline is used. The purpose of our study is to develop an alternative, safe, minimally invasive method to treat CE1 cysts, avoiding the use of toxic topic scolicides.We opt for percutaneous drainage (PD) in four patients: the intrahepatic drainage catheter is placed under CT-fluoroscopy, intracystic fluid is aspirated, and the viability of intracystic echinococcal protoscolices is assessed microscopically. Oral praziquantel (PZQ) is added to albendazole (ABZ) instead of using topical scolicidals.Protoscolices degenerate within 5 to 10 days after PZQ co-medication at a cumulative dosage of 250 to 335 mg/kg, and the cysts collapse. The cysts degenerate, and no sign of spillage nor relapse is observed in the follow-up time of up to 24 months post-intervention.In conclusion, PD combined with oral PZQ under ABZ coverage is preferable to PAIR in patients with unilocular echinococcal cysts.

Percutaneous transhepatic biliary drainage (PTBD) in patients with biliary leakage: Technical and clinical outcomes.

The purpose of this study is to evaluate the technical and clinical outcome of percutaneous transhepatic biliary drainage (PTBD) in patients with biliary leakage. All patients who underwent ultrasound-assisted PTBD between January 2017 and December 2021 due to biliary leakage with nondilated biliary systems were retrospectively evaluated for periprocedural characteristics, medical indications, technical success (successful placement of drainage catheter), clinical success (resolved leak without additional procedures), fluoroscopy time, procedure duration, and clinical outcomes. 74 patients with a mean age of 64.1 ± 15.1 years were identified. Surgery was the most common etiology of biliary leak with 93.2% of the cases. PTBD had a 91.8% (68/74) technical success rate and an 80.8% clinical success rate. The mean procedure and fluoroscopy duration were 43.5 and 18.6 minutes. Age > 65 years (P = .027) and left-sided drainage (P = .034) were significant risk factors of clinical failure. Procedure-related major complications were 2 bleedings from the liver and 1 bleeding from an intercostal artery (major complication rate 4%). PTBD is a feasible, safe, and effective treatment option in patients with biliary leakage with low complication rates.

Outcome of single-incision laparoscopic cholecystectomy compared to three-incision laparoscopic cholecystectomy for acute cholecystitis.

While single-incision laparoscopic cholecystectomy (SILC) has advantages in cosmesis and postoperative pain, its utilization has been limited. This study raises the possibility of expanding its indication to acute cholecystitis with the novel method of solo surgery under retrospective analysis. We compared the outcomes of SILC (n = 58) to those of three-incision laparoscopic cholecystectomy (TILC; n = 117) for acute cholecystitis, being performed from March 2014 to December 2015. Intraoperative results, including the operation time, did not differ significantly, except for drain catheter insertion (p = 0.004). Each group had 1 case of open conversion due to common bile duct injury. There was no significant difference in the length of hospital stay. Either group by itself was not a risk factor for complications, but in preoperative drainage for intraoperative perforation, 3 factors of intraoperative perforation, biliary complication, and history of upper abdominal operation for additional port, only American Society of Anesthesiology (ASA) scores for postoperative complication of Clavien-Dindo grades III and IV were significant risk factors. Our study findings showed comparative outcomes between both groups, providing evidence for the safety and feasibility of SILC for acute cholecystitis.

Early drainage reduces the length of hospital stay in patients with lung abscess.

Although percutaneous transthoracic catheter drainage (PCD) has been proven effective in lung abscesses, the optimal timing of PCD is still unclear. The study aimed to evaluate the safety and efficacy of early versus delayed drainage in patients with lung abscesses. This retrospective study included 103 consecutive patients with liquefied lung abscesses more than 3 cm confirmed by a CT scan received CT-guided PCD over 16 years, from July 2005 to September 2021, in a single institution were reviewed. Early drainage was defined as PCD within one week after a lung abscess was diagnosed. The primary outcome was 90-day mortality. The secondary outcomes included perioperative complications and patients' length of hospital stay (LoS). Factors associated with 90-day mortality and LoS were also analyzed. The key statistical methods were Chi-square test, Fisher's exact test, Student t-test, and Pearson correlation. Amount the 103 patients, there were 64 patients who received early PCD, and 39 patients received delayed PCD. Between the two groups, there were no significant differences in clinical characteristics, 90-day mortality, or perioperative complications. The LoS was significantly shortened in early PCD group (28.6 ± 25.5 vs. 39.3 ± 26.8 (days), p = 0.045). Higher Charlson comorbidity index, secondary lung abscess, and liver cirrhosis were associated with higher mortality (all p < 0.05). Positive sputum culture significantly increased the LoS (coefficient 19.35 (10.19, 28.50), p < 0.001). The 90-day mortality and complications were similar for early PCD and delayed PCD patients, but LoS was significantly shortened in early PCD patient.

EUS-guided transrectal drainage of pelvic abscesses: a retrospective analysis of 17 patients.

Pelvic abscess is a common complication of abdominal surgery or intestinal or gynecological diseases. Over the last decades, endoscopic ultrasound (EUS)-guided drainage has emerged as a minimally invasive alternative to percutaneous or surgical treatment of pelvic abscesses. To evaluate safety and efficacy of EUS-guided transrectal pelvic abscess drainage in a single center. From February 2017 to April 2023, all data on patients who were treated for pelvic abscesses by EUS-guided drainage in a single center, were retrospectively analyzed. A total of 17 patients were treated for pelvic abscesses by EUS-guided drainage. The procedure was technically successful and uneventful in all 17 patients (100%). Etiology of the abscess was postsurgical (n=5, 29%), secondary to medical illness (n=10, 59%) or gastrointestinal perforation (n=2, 12%). The abscess was multilocular in 5 patients (29%), the mean largest diameter was 76 mm (range 40-146 mm). Drainage was performed using 2 double pigtail stents, and in 1 patient an additional 10 Fr drainage catheter was deployed. Two patients (12%) required a second endoscopic intervention. Treatment success, defined by complete abscess resolution on follow-up CT scan along with symptom relief, was 100%. There was no need for surgical intervention. The median post-procedural hospital stay was 5 days. No recurrence was reported within a median time of follow-up of 39 months. EUS-guided transrectal drainage of pelvic abscesses using double pigtail stents is safe and highly effective. This case series contributes to the cumulative evidence that, in expert hands, EUS-guided drainage should be considered as first-line approach for treatment of pelvic abscesses.

Comparative Study of Linezolid and Vancomycin Regimens in One-Stage Surgery for Treating Limb Traumatic Osteomyelitis Caused by Methicillin-Resistant Staphylococcus aureus.

To compare the clinical outcomes of linezolid and vancomycin regimens combined with one-stage surgery in treating traumatic osteomyelitis of the limbs caused by methicillin-resistant Staphylococcus aureus (MRSA) infection. A retrospective study was performed to analyze patients with traumatic osteomyelitis of the limbs attributable to MRSA infection. All of these patients received one-stage surgery to debride their wounds, with subsequent implantation of a vancomycin-loaded calcium sulfate artificial bone. Patients received either intravenous linezolid (study group) or vancomycin (control group) during the perioperative period. The postoperative inflammatory markers, renal function, duration of drainage catheter placement, duration of antibiotic administration, length of hospital stay, adverse events, and recurrence of osteomyelitis in these two groups were compared. The study group had a shorter duration of antibiotic administration and length of hospital stay (p < 0.05). There was a significant difference in the incidences of adverse events between the two groups (5.88% and 17.65% in the study and control groups, respectively, p < 0.05). There was no recurrence in either group during the three-year follow-up period. As of year, five after the surgery, one patient in the control group had a recurrence of osteomyelitis. The linezolid regimen should be preferred to the vancomycin regimen in patients with traumatic osteomyelitis of the extremities caused by MRSA infection because the linezolid regimen showed fewer adverse events, shorter periods of antibiotic use, and shorter hospital stay. However, both treatment regimens achieved satisfactory outcomes and warranted further investigations.

Minimally invasive approach with small diameter pleural drainage catheter (Easydren®) in malignant pleural effusions

Aim: Treatment of malignant pleural effusions is drainage and chemical pleurodesis. Our aim in this study is to investigate the success and complications of the procedure in patients who underwent drainage with an 8F pleural drainage catheter due to malignant pleural effusion, in the light of the literature.&#x0D; Material and Method: The study included 124 patients who underwent 8F pleural drainage catheter (Easydren®) for malignant pleural effusion between August 2020 and October 2022. Clinical, radiological and laboratory findings of all patients were obtained from the automation system and archive files. Age, gender, etiology, number and duration of catheter drainage, complications and hospital stay of the patients were recorded.&#x0D; Results: Of the patients, 67 (54.0%) were female and 57 (45.9%) were male. The mean age was 54 (31-87). A total of 136 pleural drainage catheters were applied to 124 patients. Drainage and complete reexpansion of the lung were successful in 125 (91.9%) of 136 procedures. No acute surgical complications were observed during the application of pleural drainage catheters. The mean drainage time was 4.6 days (3 – 11). The hospital stay was 5.7 days (4-12).&#x0D; Conclusion: We believe that small diameter pleural drainage catheters are as effective as conventional chest tubes for the drainage of malignant pleural effusion with greater patient comfort. Although it has the disadvantage of rarely occlusion during follow-up, it is less invasive and has fewer complications compared to tube thoracostomy.

Peripheral VA-ECMO and pericardial drainage connected to the ECMO circuit for cardiac tamponade from blowout rupture: a case report

BackgroundLeft ventricular free wall rupture, particularly the blowout type, is still one of the most lethal complications of myocardial infarction and can cause catastrophic cardiac tamponade. Extracorporeal membrane oxygenation (ECMO) is often used to treat haemodynamic instability due to cardiac tamponade. However, elevated pericardial pressure can cause collapse of the right atrium, resulting in inadequate ECMO inflow and preventing the stabilisation of the circulation. Further, it can interfere with the venous return from the superior vena cava (SVC), increasing the intracranial pressure and reducing cerebral perfusion levels.Case presentationA 65-year-old man was hospitalised for out-of-hospital cardiac arrest. We used ECMO for cardiopulmonary resuscitation. After the establishment of ECMO, transthoracic echocardiography and left ventriculography revealed massive pericardial effusion. The treatment was supplemented with pericardial drainage since ECMO flow was frequently hampered by suction events. However, the blowout rupture led to the requirement of constant drainage from the pericardial catheter. To tend to this leak, we connected the venous cannula of ECMO and the pericardial drainage catheter. The surgery was performed with stable circulation without suction failure of ECMO. During the course of the intensive care management, the neurological prognosis of the patient was revealed to be poor, and the patient was shifted to palliative care. Unfortunately, the patient died on day 10 of hospitalisation.ConclusionWe present a case wherein the combination of pericardial drainage and ECMO was used to maintain circulation in a patient with massive pericardial effusion due to cardiac rupture.

Use of gelatin sponge to seal the biliary tract after percutaneous transhepatic biliary drainage in patients with liver transplants.

Percutaneous transhepatic biliary drainage (PTBD) is commonly used in the treatment of malign and benign biliary pathologies. Certain complications after PTBD may occur, such as biliary fistula, biliary leakage, bilioma, and hematoma. The purpose of this study was to evaluate the safety and effectiveness of using a sterile gelatin sponge to seal the biliary tract after PTBD in patients with liver transplants to prevent complications. A total of 131 biliary drainages were introduced in 97 patients, and a sterile gelatin sponge was used to seal the biliary tract after removal of the biliary drainage catheter. The patients were immediately examined for complications using ultrasound and then followed up clinically unless imaging was required. Five fluid collections within the liver with a diameter <2 cm, consistent with hematoma or bilioma, were resolved spontaneously. No hematoma or bilioma required treatment, and no biliary leakage or fistula was detected. No compli¬cations related to the use of the sponge were observed. The use of a sterile gelatin sponge is a safe and effec-tive method for sealing the biliary tract to prevent complications after PTBD in patients with liver transplants.

408. COMPARISON OF THE SHORT-TERM EFFICACY OF THORACOSCOPY COMBINED WITH GASTROSCOPY AND TRADITIONAL THORACOTOMY IN THE TREATMENT OF SPONTANEOUS ESOPHAGEAL RUPTURE

Abstract Background Early and thorough intrathoracic debridement，irrigation and catheter drainage are of great significance for the healing of esophageal rupture. This study aims to explore the surgical treatment of spontaneous esophageal rupture, reduce the trauma and improve the cure rate. Methods A total of 21 patients with spontaneous esophageal rupture were selected from June 2010 to June 2022. In the thoracoscopy combined with gastroscopy group, 12 patients were treated with thoracoscopic debridement, esophageal rupture repair, thoracic drainage with closed drainage tube, nasal drainage with gastroscope and nasal duodenal feeding tube placement. In the thoracotomy group, 9 patients performed scheduled thoracotomy. Results Compared with the thoracotomy group, the thoracoscopy combined with gastroscopy group had less incision pain, shorter operation time, less surgical bleeding, and lower incidence of incision infection, pulmonary infection and arrhythmia, with statistical significance (P &amp;lt; 0.05), while the incidence of anastomotic fistula and mortality showed no statistical significance (P &amp;gt; 0.05). Conclusion Spontaneous esophageal rupture is an emergency in thoracic surgery, and the combined operation of thoracoscopy and gastroscopy after early diagnosis has less trauma, faster recovery and good therapeutic effect.

Comparative analysis of re-entry malecot and nelaton catheters after standard percutaneous nephrolithotomy in adult patients: a cross-sectional study.

Drainage catheters are used almost routinely to provide urinary drainage, prevent extravasation of urine, and create tamponade against bleeding after percutaneous nephrolithotomy (PNL). In the literature, there is no standardized approach to determining which type of catheter is superior. In this context, we aimed to comparatively analyze two different types of catheters (re-entry malecot catheter and nelaton catheter) in terms of success and complications, which we use for drainage after a PNL operation and which have very different costs. Patients who underwent PNL for kidney stones between January 2018 and October 2022 were included in the study. The data of a total of 148 patients who had a 16-F reentry malecot nephrostomy catheter or a 16-F nelaton catheter were analyzed. In addition to the demographic characteristics of the patients, stone characteristics, operative data, hospitalization time, analgesia requirement, hemoglobin exchange, amount of blood transfusion, and postoperative data (success and complications) were comparatively evaluated. The current unit price for a reentry malecot and a nelaton catheter is 4.7 United States dollars (USD) and 0.11 USD, respectively. There were a total of 148 patients in the study, 63 of whom were nelaton catheters and 85 were reentry malecots, and the mean age was 39.95 ± 13.28years. There was no statistically significant difference between preoperative stone sizes and residual stone rates according to the groups. In addition, there was no statistically significant difference between the groups in terms of access site and stone localization. There was no significant difference between the groups in terms of complication rates according to the Clavien-Dindo classification, Hb levels, blood transfusion rates, operation times, or hospitalization times. In conclusion, if a second procedure is planned, a reentry malecot catheter may be preferred. Apart from this situation, nelaton catheters should be preferred because they are similar to reentry catheters in terms of effectiveness, and side effects and are more economical than reentry catheters in terms of cost.

Internal versus external biliary drainage in malignant biliary obstructions: is there a difference in the rate of infection?

Percutaneous biliary drainage is a frequently used method to provide biliary decompression in patients with biliary obstruction. To investigate the between drainage type and infection risk in patients treated with internal-external and external biliary drainage catheterization for malignant biliary obstruction. A total of 410 patients with malignant biliary obstruction who underwent internal-external or external biliary drainage catheterization between January 2012 and October 2016 were retrospectively evaluated. We investigated the correlation between percutaneous biliary drainage technique and infection frequency by evaluating patients with clinical findings, bile and blood cultures, complete blood counts, and blood biochemistry. There was no statistically significant difference between the selected patient groups (internal-external or external biliary drainage catheter placed) in terms of age, sex, primary diagnosis, receiving chemotherapy, catheter sizes, and outpatient-patient status. After catheterization, catheter-related infection was observed in 49 of 216 (22.7%) patients with internal-external and 18 of 127 (14.2%) patients with external biliary drainage catheters, according to the defined criteria. There was no difference in infection rate after the biliary drainage in the two groups (P > 0.05). There was also no difference concerning frequently proliferating microorganisms in bile cultures. Internal-external biliary drainage catheter placement does not bring an additional infection risk for uninfected cholestatic patients whose obstruction could be passed easily in the initial drainage.

Application of a New Approach for Laparoscopic Resection of Bismuth IIIa Hilar Cholangiocarcinoma.

Background: Hilar cholangiocarcinoma (HCCA) has a high degree of malignancy and poor prognosis, and the best long-term prognosis can only be achieved by radical resection. However, the surgical steps are complicated, and the operating space is limited, making it hard to complete laparoscopically. So our team proposes a new surgical approach for laparoscopic left-liver-first anterior radical modular orthotopic right hemihepatectomy (Lap-Larmorh). In this way, we can simplify the operation steps and reduce the difficulty. Materials and Methods: We recorded and analyzed the clinical data of 26 patients with type IIIa HCCA, who underwent laparoscopic radical resection in our department from December 2018 to January 2023. According to the laparoscopic surgical approach, we divided the patients into the new approach (NA) group (n = 14) using the Lap-Lamorh and the traditional approach (TA) group (n = 12) not using the Lap-Lamorh. Results: All surgeries in this study were completed laparoscopically with no conversion to open surgery. The operation time in the NA group and TA group had statistically significant differences, which was 372.5 (332.8, 420.0) minutes versus 423.5 (385.8, 498.8) minutes (P = .019). The two groups showed no significant difference in other characteristics (P > .05). Only 1 patient suffered from transient liver failure due to portal vein thrombosis. Patients with pleural effusion or ascites were cured by catheter drainage and enhanced nutrition. Conclusion: Lap-Larmorh reduces the difficulty of serving the vessels at the second and third hepatic hilum by splitting the right and left livers early intraoperatively. The new approach is more suitable for the narrow space of laparoscopic surgery and reflects the no-touch principle of oncology.

Management of Cerebrospinal Fluid Leakage after Microvascular Decompression Surgery: Clinical Strategy.

(1) Background: Cerebrospinal fluid (CSF) leakage is one of the most common complications of microvascular decompression (MVD) surgery. Before fatal complications, such as intracranial infection, occur, early recognition and prompt treatment are essential. (2) Methods: The clinical data of 475 patients who underwent MVD surgery from September 2020 to March 2023 were retrospectively analyzed. In these patients, if there were any symptoms of CSF leakage, and if CSF leakage was evident, a lumbar drainage catheter was inserted immediately. (3) Results: CSF leakage was suspected in 18 (3.8%) patients. Five of these patients (1.1%) showed signs of CSF leakage during conservative management and subsequently underwent catheter insertion for lumbar drainage. The lumbar drain was removed after an average of 5.2 days, resulting in an average hospitalization of 14.8 days. In all 5 patients, CSF leakage was resolved without reoperation. (4) Conclusions: Our treatment strategy prevented the development of fatal complications. Close observation of the symptoms and postoperative temporal bone computed tomography and audiometry are considered to be good evaluation methods for all patients. If CSF leakage is certain, it is important to perform lumbar drainage immediately.

Diagnostic Ability and Safety of Repeated Pancreatic Juice Cytology Using an Endoscopic Nasopancreatic Drainage Catheter for Pancreatic Ductal Adenocarcinoma: A Multicenter Prospective Study.

Pathological examination is essential for the diagnosis and treatment of pancreatic ductal adenocarcinoma (PDAC). Moreover, a reliable pathological diagnosis is extremely important for improving prognosis, especially in early-stage PDAC. This study prospectively evaluated the usefulness of repeated pancreatic juice cytology (PJC) using an endoscopic nasopancreatic drainage (ENPD) catheter for the diagnosis of PDAC. We enrolled 82 patients suspected of having resectable PDAC, based on imaging studies, and judged the necessity for cytology. The diagnostic yield of up to six repeated PJCs and the incidence of complications, such as pancreatitis, was evaluated. A total of 60 patients were diagnosed with PDAC. The overall sensitivity and specificity were 46.7% and 95.5%, respectively. The cumulative positivity rate increased with the number of sampling sessions, reaching 58.3% in the sixth session. The sensitivity was significantly higher in the pancreatic head than in the pancreatic tail (p = 0.043). Additionally, it was 100% in four patients with a tumor size ≤10 mm. Pancreatitis occurred in six patients (7.3%), all of whom were treated conservatively. In the diagnosis of PDAC, repeated PJC using an ENPD catheter revealed a cumulative effect of sensitivity up to six times and an excellent diagnostic yield for small PDAC.
