Retrospective Study on Anterolateral Mini-Thoracotomy in Emergency Surgical Drainage for Massive Pericardial Effusion Including Sternotomy Case

Background: The conventional method for managing the surgical drainage of an acute massive pericardial effusion typically involves a median sternotomy. Nevertheless, advancements in surgical optics and tools have enabled the utilization of progressively smaller incisions, such as a left anterolateral thoracotomy, for the same purpose. Aim of the Study: This study aimed to assess the surgical outcomes of left anterolateral mini-thoracotomy compared to median sternotomy for draining acute massive pericardial effusion. Methods: This research took place in the Cardiac Surgery Department at Ibrahim Cardiac and Research Institute, following approval from the local ethics committee, from June 2021 to June 2023. Fourteen patients with acute massive pericardial effusion necessitating emergency surgical drainage were included. The investigation concentrated on evaluating operative and short-term postoperative results to gauge the influence of two surgical drainage methods on patients' quality of life. Result: Both groups exhibited similar age, preoperative comorbidities, and ejection fraction. The sternotomy group required more operation time than the left anterolateral mini-thoracotomy group. Furthermore, the sternotomy group had a prolonged stay in the intensive care unit and hospital compared to the left anterolateral mini-thoracotomy group. Similar rates were observed for blood transfusion and chest tube drainage. However, two cases of superficial wound infection occurred in the sternotomy group. In the anterolateral thoracotomy group, no patients required conversion to full sternotomy, and all patients were alive at the one-month follow-up after hospital discharge. Conclusion: Employing a left anterolateral mini-thoracotomy for draining acute massive pericardial effusion was deemed a secure and reliable alternative to the traditional median sternotomy incision. Despite its limited operating field, requiring proficiency, this approach preserved sternal integrity, offered a more aesthetically pleasing incision, reduced the risk of wound infection, and decreased the need for analgesia. Additionally, it was associated with a faster recovery process and a shorter stay in the intensive care unit (ICU). (Bangladesh Heart Journal 2024; 39(2): 161-167

A posterior pericardial chest tube is associated with reduced incidence of postoperative atrial fibrillation after cardiac surgery: A propensity score–matched study

ObjectivePostoperative atrial fibrillation (POAF) is a common complication after cardiac surgery that is associated with other adverse outcomes. Recent studies have shown that drainage of pericardial effusion by a posterior pericardial incision reduces the incidence of POAF. An alternative approach is a chest tube placed posteriorly in the pericardium. We evaluated whether the use of a posterior pericardial drain was associated with reduced risk of POAF in patients undergoing coronary artery bypass graft (CABG) and/or aortic valve replacement (AVR). MethodsThis observational study included 2535 patients who underwent CABG (n = 1997), AVR (n = 293), or combined CABG and AVR (n = 245) in Iceland from 2002 to 2020. From our study population, 553 (22%) received a 20-Fr posterior pericardial chest tube in addition to standard mediastinal and left pleural drains. The incidence of POAF in patients with and without a posterior pericardial drain was compared before and after 1:1 propensity score matching. ResultsOf 2535 patients, 1100 were included in the matched cohort. The incidence of POAF was lower in patients receiving posterior pericardial chest tube drainage compared with the control group, both before (34% vs 43%, P < .001) and after (33% vs 43%, P = .002) matching. In a multivariable analysis, posterior pericardial chest tube drainage was independently associated with a reduced risk for POAF (adjusted odds ratio 0.67; 95% confidence interval, 0.52-0.88; P = .003). ConclusionsThis observational study suggested that posterior pericardial chest tube drainage is associated with a significant reduction of POAF after routine CABG and/or AVR procedures. The results are hypothesis-generating and must be confirmed in prospective randomized trials.

627. LEFT THORACOSCOPIC PRIMARY REPAIR OF ESOPHAGEAL PERFORATION SECONDARY TO BOERHAAVE SYNDROME

Abstract Background With the advancement of the minimally invasive surgical techniques, more and more acute surgical conditions including esophageal perforations can be performed safely using minimally invasive surgical approach. Methods A middle aged male patient presented to our department with 3 days history of epigastric pain and vomiting. He was febrile on admission and investigation revealed the left sided esophageal perforation due to Boerhaave Syndrome with left sided pleural effusion. He underwent left thoracoscopic primary repair of esophageal perforation and wash out successfully. This is the video of the thoracoscopic primary repair of the perforation. Patient was put in the right lateral semi prone position, the area of perforation was identified by careful dissection of the pleura and repaired was performed in 2 layers. The pleura cavity was washed out with warm saline and underwater sealed chest tube drain was inserted. Results Post operatively patient was transferred to surgical intensive care unit for 1 day. Patient was kept nil by mouth with parenteral nutrition for 7 days. Contrast study was performed on post operative day 7 and started oral feeding when there was no evidence of leakage. Patient recovered and discharged well. Conclusion Thoracoscopic primary repair with wash out of spontaneous esophageal perforation secondary to Boerrhave Syndrome is challenging however it is safe and can be performed successfully. https://drive.google.com/file/d/1JTfJLV-ngUBwzMybGV4FL8EEQB-ysj9O/view

The impact of transanal drainage tube on the incidence of anastomotic leakage and small bowel obstruction in radical surgery (Dixon) for rectal cancer: a retrospective cohort study.

Anastomotic leakage (AL) and small bowel obstruction (SBO) are common complications after rectal cancer radical surgery (Dixon). Although the commonly used defunctioning stoma (DS) can reduce the incidence and harm of AL, it increases the probability of other adverse consequences, including SBO. Therefore, a safe and effective method for preventing the complications related to the radical surgery of rectal cancer is urgently needed. Previous studies have found that transanal drainage tube (TDT) can have a positive impact on the incidence of these two complications by draining gas and feces from the intestinal lumen, without causing other serious consequences. Therefore, this article further explores the clinical benefits that TDT can bring by analyzing the clinical data of postoperative patients with rectal cancer. This study included 221 patients who underwent radical surgery (Dixon) for rectal cancer in Hubei Cancer Hospital from September 2020 to February 2023, determine whether it meets the inclusion criteria of this study based on preoperative examination, intraoperative exploration results, and treatment methods. DS was used in 70 patients and TDT in 88 patients during the surgery; meanwhile, no protective anastomotic measures were applied in 63 patients. Seventy patients subjected to DS were categorized as group 1, 88 patients subjected to TDT as group 2, and 63 patients with no protective measures for anastomosis as group 3. Through postoperative clinical manifestations, imaging examinations, and laboratory tests, a total of 18 cases of AL and 30 cases of SBO were identified in the three groups. The effectiveness of TDT and that of other surgical procedures in preventing complications, accelerating postoperative recovery, and reducing surgical costs were compared through univariate and multivariate analyses. The clinical features of the three groups have baseline comparability. No statistically difference was noted in baseline characteristics between three groups (all P>0.05). The incidence of AL and SBO in group 1 are 7.1% and 27.1%, in group 2 are 3.4% and 4.5%, and in group 3 are 15.9% and 11.1%. Compared to patients in no protective anastomotic measures with TDT and DS, TDT has a lower incidence of postoperative AL (P<0.05) and SBO (P>0.05), and faster postoperative recovery (P<0.05). The cost of inpatient surgery is not significantly different (P>0.05). Although DS can reduce the incidence of AL to a certain extent (P>0.05), it significantly increased the incidence of SBO (P<0.05), delayed postoperative defecation time (P<0.05) and caused higher cost (P<0.001). Compared to DS, the incidence of AL in TDT is not significantly different (P>0.05), but the incidence of SBO is noticeably lower (P<0.001), with faster postoperative recovery and less cost (P<0.05). TDT is a safer, more effective, and more economical surgery for preventing postoperative complications.

Contribution of fluorescence imaging to thoracoscopic anatomical segmentectomy: a multicenter propensity matching analysis.

Thoracoscopic anatomical segmentectomy is increasingly recognized for managing early-stage lung cancer. However accurately identifying intersegmental planes (ISPs), especially in complex lung segments, remains challenging. In comparison to conventional methods, fluorescence imaging represents a novel solution. This study aimed to examine the potential benefits of fluorescence imaging in single-port thoracoscopic anatomical segmentectomy. A multicenter (three regional hospitals), retrospective, comparative analysis was conducted using data from 402 consecutive patients who underwent single-port thoracoscopic anatomical segmentectomy from June 2020 to December 2022. The cohort included 191 patients treated with the fluorescence method and 211 patients treated with the modified inflation-deflation method. Among the cohort, 130 patients were placed in the simple segmentectomy group and 272 in the complex segmentectomy group. Propensity score matching (PSM) was used to adjust for baseline differences between the fluorescence and modified inflation-deflation subgroups in the complex segmentectomy group. Perioperative outcomes were compared between the groups. In the simple segmentectomy group, no significant differences were observed between the fluorescence and modified inflation-deflation methods regarding segmental resection time, intraoperative blood loss, postoperative chest tube drainage and duration, postoperative pain, length of hospital stay, complication rate, or hospital costs. In the complex segmentectomy group, however, fluorescence imaging significantly shortened segmental resection time (69.37±28.22 vs. 78.80±34.66 min; P=0.03), while reducing intraoperative blood loss (P=0.046); and improving visual analogue scale (VAS) pain scores on the first postoperative day (P=0.006). Both methods demonstrated comparable safety and oncologic effectiveness. Fluorescence-guided single-port thoracoscopic anatomical segmentectomy demonstrated comparable perioperative safety and effectiveness to the modified inflation-deflation technique while offering advantages, such as shorter segmental resection time, for complex segmentectomies.

Shorter Drainage Tube to the Pancreatic Stump Reduces Pancreatic Fistula After Distal Pancreatectomy.

We investigated the relationship between the length of a prophylactic closed-suction drainage tube and clinically relevant postoperative pancreatic fistula (CR-POPF) in distal pancreatectomy (DP). The clinical data of 76 patients who underwent DP using a reinforced stapler for the division of the pancreas at Ehime University Hospital between December 2017 and May 2023 were retrospectively analyzed. Laparoscopic DP was performed in 41 patients (53.9%). Closed-suction drainage was performed using a 19Fr ExuFlow Round Drain with a vacuum bulb. The drainage tube length was defined as the distance between the peripancreatic stump site and the abdominal wall insertion site using abdominal radiography. CR-POPF was observed in 12 patients (15.8%). Univariate analyses demonstrated that male sex (P=0.020), American Society of Anesthesiologists Physical Status (P=0.017), current smoking (P=0.005), and drainage tube length (P<0.001) were significantly associated with CR-POPF. The optimal cut-off value of drainage tube length for CR-POPF was 220mm (area under the receiver operating characteristic curve=0.80). In multivariate analyses, drainage tube length (≥220mm) was the sole independent predictor for CR-POPF (odds ratio, 6.59; P=0.023). According to computed tomography performed ∼1 week after surgery, the median volume of peripancreatic fluid collection was significantly higher in the long drainage tube group than in the short drainage tube group (P<0.001). A drainage tube inserted at a shorter distance to the pancreatic stump may reduce the incidence of CR-POPF after DP.

Outcome of Early and Late Onset Fontan Operation in Patients with Univentricular Heart Repair

Objective: To determine the outcome of early and late-onset Fontan operation in patients with univentricular heart repair. Study Design: Quasi-experimental study. Place and Duration of the Study: Department of Paediatric Cardiology, National Institute of Cardiovascular Diseases, Karachi Pakistan, from Jan 2019 to Dec 2021. Methodology: During the study period, 121 patients of both genders, up to any age, with functionally univentricular hearts and who planned to undergo Fontan procedures were included. All cases were divided into two groups, Group-A had patients who underwent extra-cardiac Fontan at age ≤6 years, while Group B had patients who underwent extra-cardiac Fontan at age &gt;6 years. Pre-procedure diagnosis, demographic, anatomic and hemodynamic characteristics, post-Fontan procedure morbidity and mortality were noted. Results: As per inclusion/exclusion criteria, 121 cases underwent Fontan surgery during the study period. There were 61(50.4%) male patients. Overall, the mean age was 7.02±4.6 years. Seventy-six 76(61.2%) cases were in Group-A and 45(38.8%) in Group-B. Mortality (within 30 days post-surgery) was reported in 11(9.1%) patients. Except for the mean duration of chest tube drainage ((0.010), there was no difference in terms of post-Fontan surgery outcomes between both study groups (p&gt;0.05). Conclusion: The age of the patients at the time of the Fontan procedure did not affect the outcomes.

A case report of a bleeding case after removal of chest drain after lung surgery.

Postoperative bleeding after lobectomy is relatively rare. By analyzing and discussing the case history and management of hemorrhagic shock caused by chest tube removal after lobectomy, we can achieve the purpose of preventing postoperative bleeding after thoracic surgery and reducing postoperative complications, which can help avoid the risk of second surgery, shorten the patient's hospital stay, reduce the cost of medical care, and improve the patient's quality of life. A case of bleeding from tube removal after lobectomy. The bleeding from chest drain removal on the 3rd day after thoracoscopic lobectomy resulted in hemorrhagic shock, which was stopped by thoracoscopic exploration again under active antishock, and there was no recurrence of bleeding after the operation, and the patient was discharged from the hospital after chest drain removal. Enhanced computed tomography of the chest revealed a space-occupying lesion in the middle lobe of the right lung. Thoracoscopy was performed again on the condition of active anti-shock. On the third day after thoracoscopic lobectomy, the patient underwent removal of the chest drain and subsequently experienced hemorrhagic shock. Given the necessity of maintaining anti-shock measures, the patient was subjected to a second thoracoscopic exploration with the objective of halting the hemorrhage. Following this procedure, the patient did not present with any further episodes of bleeding. Subsequently, a new chest drain was placed, and once the drainage flow had diminished to an acceptable level, the chest drain was removed. The patient subsequently made a full recovery and was discharged from the hospital. Even if the safely inserted drain tube is removed, the thoracic surgeon must be aware of possible vascular bleeding.

Perioperative and mid-term outcomes of robotic-assisted versus video-assisted minimally invasive esophagectomy for esophageal cancer: a retrospective propensity-matched analysis of 842 patients.

Comparing the safety, effectiveness, and mid-term survival rates of robot-assisted minimally invasive esophagectomy (RAMIE) and video-assisted minimally invasive esophagectomy (VAMIE). A total of 842 patients undergoing minimally invasive esophagectomy were analyzed, including 694 patients in VAMIE group and 148 in RAMIE group. PSM analysis was applied to generate matched pairs for further comparison. Operative outcomes, postoperative complications and Mid-term outcomes were compared between all patients in matched groups. After 1:4 PSM, 148 patients in the RAMIE and 592 patients in the VAMIE. Compared to VAMIE, RAMIE exhibited earlier removal of chest and neck drainage tubes, shorter postoperative hospital stays, and a higher number of lymph node dissections. However, the surgical duration of RAMIE was longer than that of VAMIE. Postoperative complications were no statistically significant between the RAMIE and VAMIE groups. There was no statistically significant difference in the 3-year OS and DFS between the two groups. Compared to VAMIE, RAMIE emerges as a viable and safe surgical approach and suggests RAMIE as a potential alternative to minimally invasive esophagectomy.

Influence of humanistic care-based operating room nursing on safety, recovery, and satisfaction after radical surgery for colorectal carcinoma

BACKGROUND Radical surgery is a preferred treatment for colorectal carcinoma, wherein nursing intervention is essential for postoperative recovery and prevention of complications. Recently, the application of humanistic care in medical care has attracted attention. Humanistic care emphasizes comprehensive care, with importance attached to patients’ physical needs as well as psychological and emotional support to provide more humane and personalized care services. However, no clinical reports have examined the use of humanistic care in patients undergoing radical surgery for colorectal carcinoma. AIM To investigate the influence of humanistic care-based operating room nursing on the safety, postoperative recovery, and nursing satisfaction of patients who have undergone radical surgery for colorectal carcinoma. METHODS In total, 120 patients with rectal cancer who underwent surgery in Zhongnan Hospital of Wuhan University between August 2023 and March 2024 were selected and grouped based on the nursing methods employed. Of these patients, 55 were treated with routine nursing intervention (control group) and 65 were provided humanistic care-based operating room nursing (research group). The patients’ vital signs were recorded, including systolic/diastolic blood pressure (SBP/DBP) and heart beats per minute (BPM), as well as serum stress indices, including norepinephrine (NE), adrenal hormone (AD), and cortisol (Cor). Postoperative recovery and complications were also recorded. Patients’ negative emotions, life hope, and nursing satisfaction were evaluated using the Self-rating Depression/Anxiety Scale (SDS/SAS), Herth Hope Index (HHI), and self-developed nursing satisfaction questionnaire, respectively. RESULTS During emergence from anesthesia, SBP, DBP, and BPM levels were found to be lower in the research group than those in the control group, also serum Cor, AD, and NE levels were lower. In addition, the research group had shorter operative, awakening, anal exhaust, first postoperative ambulation, drainage tube removal, intestinal recovery, and hospital times. The total complication rate and the SDS and SAS scores were lower in the research group than those in the control group. The HHI and nursing satisfaction scores were higher in the research group. CONCLUSION Humanistic care-based operating room nursing can mitigate physiological stress responses, reduce postoperative complications, promote postoperative recovery, relieve adverse psychological emotions, and enhance life hope and nursing satisfaction in patients undergoing radical surgery for colorectal carcinoma, which can be popularized in clinical practice.

Comparative analysis of stereotactic soft-channel and hard-channel aspiration in the treatment of primary brainstem hemorrhage

ObjectiveTo evaluate the efficacy of stereotactic soft-channel and hard-channel aspiration in the treatment of primary brainstem hemorrhage. MethodsThe clinical data of 146 patients with primary brainstem hemorrhage at the First Hospital of Hebei Medical University from August 2014 to August 2023 were analyzed. At admission, 146 patients were divided into soft-channel group or hard-channel group using a random number table method. Sixty-five patients were treated with stereotactic soft-channel aspiration, and 81 patients were treated with stereotactic hard-channel aspiration. The amount of residual hematoma was evaluated by head CT immediately after the operation, and the length of the indwelling drainage tube was recorded. Survival status at 30d after the operation and treatment outcome (mRS score and GOS score) at 90d after the operation were also recorded. The amount of residual hematoma immediately after the operation, the length of the indwelling drainage tube after the operation, the mortality rate and the treatment outcome were compared between the two groups. ResultsThere was significant difference in the mortality rate 30d after the operation (41.5% vs. 14.8%, χ2 = 20.192, P = 0.035) between stereotactic soft-channel aspiration and stereotactic hard-channel aspiration for brainstem hemorrhage. The hard-channel group had a higher survival rate. There was significant difference in the treatment outcome at 90 days after treatment (18.5% vs. 32.1%, χ2 = 4.783, P = 0.047). The hard-channel group showed better treatment outcomes 90 days after surgery. ConclusionStereotactic hard-channel aspiration for primary brainstem hemorrhage has greater clearance efficiency than soft-channel aspiration and can significantly reduce patient mortality and improve treatment outcomes. Stereotactic hard-channel aspiration is a safe and effective method for treating primary brainstem hemorrhage.

Trends in Duodenal Injury Severity, Repair, and Mortality Over Time

IntroductionOutcomes for patients with traumatic duodenal injury are determined by the location of the injury, injury severity, and associated injuries. We hypothesized that there is an association among the increased frequency of firearm injuries, the severity of duodenal injuries, trends in repair techniques, and mortality. MethodsDuodenal injuries managed at an adult level 1 hospital from 2000 to 2022 were identified. Demographics, injury type, the American Association for the Surgery of Trauma (AAST) grade, type of surgical repair, and mortality data were obtained and aggregated into two periods (2000 to June 2011 and July 2011 to 2022) to evaluate trends over time. P values < 0.05 were considered significant. ResultsOne hundred eighty eight cases were identified. Duodenal injuries due to firearms increased over time (30% versus 55%, P < 0.001). The distribution of AAST injury grade shifted over time with fewer grade 1 and more grade 2 to 4 injuries in the later period (P = 0.002). AAST grade 2 injuries or higher were more likely due to firearms (P < 0.001). Despite more high-grade injuries, there was no change in the use of primary repair with or without tube drainage (61% versus 70%, P = 0.35) and there was no change in mortality (15% versus 17%, P value 0.62) between the time periods. ConclusionsThere was a proportional increase in the number of duodenal injuries caused by firearms. Higher grade duodenal injuries were more common with firearm injuries and were predominately repaired with simple techniques with no increase in mortality.

Analysis of decision-making factors for defunctioning ileostomy after rectal cancer surgery and their impact on perioperative recovery: a retrospective study of 1082 patients.

To explore the decision-making factors for defunctioning ileostomy (DI) after rectal cancer surgery and to analyze the impact of the DI on perioperative outcomes. A retrospective case-control study was conducted that included rectal cancer patients who underwent low anterior resection from January 2013 to December 2023. Among them, 33 patients did not undergo DI but with anastomotic leakage (AL) after surgery, and 1030 patients were without AL. Preoperative, operative and tumor factors between these two groups were compared to explore the decision-making factors for DI. Meanwhile, the differences of perioperative outcomes between the DI group of 381 cases and non-DI group of 701 cases were compared. For preoperative factors, the proportions of male patients and preoperative chemoradiotherapy (CRT) in the AL with non-DI group were greater than those in the non-AL group (p < 0.05); for operative factors, the proportion of patients in the AL with non-DI group with a surgical time > 180min were greater (p < 0.05); for tumor factors, the proportion of T3-4 stage was higher in the AL with non-DI group (p < 0.05). Multiple regression analysis revealed that male sex and preoperative CRT were the independent risk factors affecting DI. For perioperative outcomes, the DI did not reduce the incidence of all and symptomatic AL and non-AL postoperative complications (p > 0.05) but with 12.07% stoma-related complications, and increase hospitalization costs (p < 0.05); however, it can shorten the postoperative hospital stay, pelvic drainage tube removal time, and reduce the anal tube placement rate and readmission rate (all p < 0.05). Male patients and preoperative CRT were the independent risk factors affect the decision of DI in our study, and DI can shorten the postoperative hospitalization, pelvic drainage tube removal time, and decrease the anal tube placement rate and readmission rate during the perioperative period but with a higher economic cost.

Rupture of intrahepatic bile duct after ERCP for common bile duct stone: A case report of rare complications.

Complications after endoscopic retrograde cholangiopancreatography (ERCP) are diverse and usually treated with nonoperative management or percutaneous drainage; however, there are still some rare, life-threatening complications. This is an extremely rare case of biliary peritonitis caused by rupture of the intrahepatic bile duct after ERCP. A 63-year-old male underwent ERCP for common bile duct stones. On the second day after the procedure, the patient developed sepsis and abdominal distention. Contrast-enhanced computed tomography revealed a subcapsular hepatic fluid collection attached to the bile duct of segment VII. Sepsis resulted in liver parenchyma rupture and intrahepatic bile duct injury after ERCP. Intraoperative cholangiography revealed a connection between a hole in the liver parenchymal surface and the intrahepatic bile duct. Surgeons performed the cholecystectomy, inserted a T-tube into the common bile duct stones, sutured the defect, and put 2 drainage tubes around the lesion. Postoperative recovery was uneventful, and the patient was discharged on the 17th postoperative day. Intrahepatic bile duct perforation after ERCP can lead to rupture of the liver parenchyma, biloma, or abdominal peritonitis. Multidisciplinary management is necessary to achieve favorable outcomes.

Cholecystopleural fistula: A case report and literature review.

Gallstone with acute cholecystitis is one of the most common diseases in the clinic. If the disease is serious, gallbladder gangrene, perforation, and sepsis may be caused. Gallbladder diseases rarely cause thoracic-related complications, especially pleural fistula, which is very rare in clinical practice. A 52-year-old male patient was admitted to the emergency department for 1 month with recurrent right middle and upper abdominal pain. Computed tomography diagnosis: cholecystitis and peri-inflammation, small abscess around the base of the gallbladder, local peritonitis, and bilateral pleural effusion. After admission, conservative treatment was given. On the 4th day of admission, the symptoms worsened, and an emergency catheter drainage was performed on the right thoracic cavity to extract 900 mL of dark yellow effusion. After the operation, a large amount of bili-like fluid was continuously drained from the thoracic drainage tube. After the iatrogenic biliary fistula caused by thoracic puncture was excluded, cholecystopleural fistula was considered to be cholecystopleural fistula. On the 6th day of admission, endoscopic retrograde cholangiopancreatography (ERCP) + cholecystography + Oddi sphincterotomy + laminating biliary stent was performed in the emergency department, and cholecystopleural fistula was confirmed during the operation. The patient recovered well after surgery, computed tomography examination on the 20th day after surgery indicated that pleural effusion was significantly reduced, and the patient was cured and discharged. The patient returned to the hospital 8 months after the ERCP operation to pull out the bile duct-covered stent. The patient did not complain of any discomfort after the postoperative follow-up for 3 years, and no recurrence of stones, empyema, and other conditions was found. Cholecystopleural fistula is one of the serious complications of acute cholecystitis, which is easy to misdiagnose clinically. If the gallbladder inflammation is severe, accompanied by pleural effusion, the pleural effusion is bili-like liquid, or the content of bilirubin is abnormally elevated, the existence of the disease should be considered. Once the diagnosis is clear, active surgical intervention is needed to reduce the occurrence of complications. Endoscopic therapy (ERCP) can be used as both a diagnostic method and an important minimally invasive treatment.

Subxiphoid Single-Port Robotic Thymectomy Using the Single-Port Robotic System versus VATS: A Multi-Institutional, Retrospective, and Propensity Score-Matched Study.

Subxiphoid thymectomy is a novel alternative to the transthoracic approach and sternotomy, with potential benefits, such as reduced postoperative pain and faster recovery. We previously reported the initial experience with subxiphoid single-port robotic-assisted thoracic surgery (SRATS) thymectomy using the single-port robotic system (SPS). However, the efficacy of this technique remains unknown. Thus, this study examined the multi-institutional experience with SRATS thymectomy and compared the perioperative outcomes of this technique to those of subxiphoid single-port video-assisted thoracic surgery (SVATS) thymectomy. The data of patients who underwent subxiphoid SRATS and SVATS thymectomy, performed by three thoracic surgeons at three institutions between September 2018 and May 2024, were retrospectively collected. In total, 110 patients were included, with 85 and 25 undergoing SRATS and SVATS thymectomy, respectively. After propensity score matching, 25 patients were included in each group. The SRATS group was associated with a lower conversion rate to multi-port surgery (0% vs. 20%, p = 0.05), shorter chest tube drainage duration (1.32 ± 0.75 vs. 2.00 ± 1.29 days, p = 0.003), and a shorter postoperative hospital stay (2.52 ± 1.00 vs. 5.08 ± 5.20 days, p = 0.003). Subxiphoid SRATS thymectomy using the SPS is feasible and is a good alternative to conventional thymectomy. Further studies are necessary to confirm its benefits.

Safety and feasibility of percutaneous abdominal lavage cytology screening (PACS) prior to surgical resection for pancreatic cancer.

This study aimed to evaluate the feasibility, safety, diagnostic yield, and technical aspects of percutaneous abdominal lavage cytology screening (PACS) in patients with resectable pancreatic cancer. This single-center, retrospective study included patients with resectable pancreatic cancer who underwent PACS before pancreatectomy between May 2022 and October 2023. The technical success rate, position of the drainage tube, volume of fluid administered, volume of fluid retrieved, fluid retrieval rate, and adverse events were evaluated. The cytological results of PACS were compared with those of surgical peritoneal lavage performed during pancreatectomy. Forty-four patients were enrolled in this study. The technical success rate for PACS was 100%. Drainage tube placement was outside the pouch of Douglas in all patients in the right-sided abdominal approach group (n = 10), whereas the placement was in the pouch of Douglas in all patients in the suprapubic approach group (n = 34). The mean volume of fluid administered, mean volume of fluid retrieved, and fluid retrieval rate were 185.0 ± 22.9ml vs. 97.1 ± 32.0ml (p < 0.001), 36.8 ± 25.6ml vs. 50.5 ± 21.6ml (p = 0.059), and 19.0 ± 12.4% vs. 54.9 ± 21.9% (p < 0.001) in the right abdominal approach and suprapubic approach groups, respectively. No adverse events were reported. The cytological results were benign in 42 patients; no discrepancy was observed in the results of surgical peritoneal lavage (n = 36). PACS is a feasible and safe procedure that can be performed before pancreatectomy in patients with resectable pancreatic cancer. the suprapubic approach may be ideal and PACS could be a screening method to detect carcinomatous peritonitis.

Spontaneous hemopneumothorax causing life-threatening hemorrhage: a case report

BackgroundSpontaneous hemopneumothorax is a rare condition that can be life-threatening if not promptly diagnosed and treated. We report a case of early treatment with transcatheter arterial embolization and video-assisted thoracoscopic surgery.Case presentationA 19-year-old Japanese male was diagnosed with left pneumothorax and underwent chest tube drainage. A total of 10 hours after admission, the patient developed dyspnea, chest pain, and sudden massive bloody effusion. Contrast-enhanced computed tomography revealed contrast extravasation near the left lung apex, and spontaneous hemopneumothorax was diagnosed. Angiography revealed bleeding from a branch of the subscapular artery and transcatheter arterial embolization was performed. The patient underwent video-assisted thoracoscopic surgery and recovered uneventfully.ConclusionsAnesthesiologists involved in urgent surgeries must be aware that a patient with spontaneous pneumothorax can develop a hemopneumothorax, even when full lung expansion has been obtained following chest tube drainage, owing to latent aberrant artery disruption. Interprofessional team engagement is essential for spontaneous hemopneumothorax management.

Efficacy and prognostic analysis of carbon nanotracers combined with the da Vinci robot in the treatment of esophageal cancer.

Traditional methods cannot clearly visualize esophageal cancer (EC) tumor contours and metastases, which limits the clinical application of da Vinci robot-assisted surgery. To investigate the efficacy of the da Vinci robot in combination with nanocarbon lymph node tracers in radical surgery of EC. In total, 104 patients with early-stage EC who were admitted to Liuzhou worker's Hospital from January 2020 to June 2023 were enrolled. The patients were assigned to an observation group (n = 52), which underwent da Vinci robot-assisted minimally invasive esophagectomy (RAMIE) with the intraoperative use of nanocarbon tracers, and a control group (n = 52), which underwent traditional surgery treatment. The operation time, intraoperative blood loss, postoperative drainage tube indwelling time, hospital stay, number of lymph nodes dissected, incidence of complications, and long-term curative effects were comparatively analyzed. The postoperative stress response C-reactive protein (CRP), cortisol, epinephrine (E) and inflammatory response interleukin (IL)-6, IL-8, IL-10, and tumor necrosis factor-alpha (TNF-α) were evaluated. Compared with the control group, the observation group had significantly lower postoperative CRP, cortisol, and E levels (P < 0.05) with a milder inflammatory response, as indicated by lower IL-6, IL-10, and TNF-α levels (P < 0.05). Patients who underwent RAMIE had less intraoperative blood loss and shorter operation times and hospital stays than those who underwent traditional surgery. The average number of dissected lymph nodes, time of lymph node dissection, and mean smallest lymph node diameter were all significantly lower in the observation group (P < 0.05). The rate of postoperative complications was 5.77% in the observation group, significantly lower than the 15.38% observed in the control group. Furthermore, the lymphatic metastasis rate, reoperation rate, and 12- and 24-month cumulative mortality in the observation group were 1.92%, 0%, 0%, and 0%, respectively, all of which were significantly lower than those in the control group (P < 0.05). The treatment of EC using the da Vinci robot combined with nanocarbon lymph node tracers can achieve good surgical outcomes and demonstrates promising clinical applications.

Uncommon threads: pneumopericardium complexity following liver catheter removal in pancreatic cancer

Pneumopericardium, the presence of air within the pericardial sac, is a rare but critical condition that can lead to severe complications such as tension pneumopericardium and cardiac tamponade, causing hemodynamic instability and necessitating immediate intervention. Various etiologies include congenital defects, post-surgical complications, infections, and trauma. Malignancies, such as advanced esophageal cancer or lung carcinoma, can also cause pneumopericardium via fistula formation. Multimodal imaging, including chest X-ray, echocardiography, and computed tomography (CT), is essential for diagnosis. This case report discusses a 65-year-old male with advanced pancreatic adenocarcinoma who developed pneumopericardium following the removal of a left lobe liver drainage catheter. Initial CT imaging revealed liver lesions suspicious for metastatic disease or abscess, leading to drainage procedures. Following the removal of the drainage tube, the patient experienced respiratory distress and hypotension, and computed tomography pulmonary angiogram (CTPA) revealed pneumopericardium, likely due to a fistula formed between the abscess and pericardium. Despite no echocardiographic signs of tamponade, the patient’s persistent hypotension warranted CT-guided pericardiocentesis, resulting in gradual blood pressure improvement. This case highlights the intricate interplay between malignancy, infection, and procedural complications in developing pneumopericardium. It emphasizes the need for a multidisciplinary approach and the importance of considering both the quantity and rate of air accumulation when assessing the risk of hemodynamic compromise. The patient’s hemodynamic instability and subsequent improvement following pericardiocentesis underscore the critical role of timely intervention in managing this condition.
