Introduction

Liver hydatid cysts remain a significant public health issue in Turkey, the Middle East, East Asia, and Russia. Surgical treatments are often employed for certain stages of this disease. However, the necessity of simultaneous cholecystectomy during these procedures remains unclear. Treating symptoms related to subsequent cholelithiasis can become more challenging. This study investigates the necessity of simultaneous cholecystectomy by following patients who underwent hydatid cyst surgery with or without concurrent cholecystectomy.

Materials and methods

Patients who underwent surgery for hydatid cysts between 2019 and 2024 at the General Surgery Clinic of Ankara Bilkent City Hospital were retrospectively reviewed. A total of 97 patients were included, with 56 (54.32 %) undergoing cholecystectomy along with hydatid cyst surgery (Group 1) and 41 (45.68 %) not undergoing cholecystectomy (Group 2).
Preoperative clinical, laboratory, and radiological findings, as well as intraoperative data, morbidity, mortality, and postoperative symptoms, were analyzed.

Results

Patients in Group 1 had longer hospital stays, higher blood loss, and significantly higher Clavien-Dindo complication scores. In the postoperative follow-up of Group 2, 8 patients (19.51 %) developed stones or sludge, and 1 patient (2.4 %) developed polyps. Four patients (9.75 %) presented to the emergency department with cholecystitis symptoms. A total of 5 patients (12.19 %), including 4 with symptomatic cholelithiasis (9.7 %) and 1 with gallbladder polyps (2.4 %), underwent elective cholecystectomy. Two (40 %) of these cholecystectomies were performed laparoscopically, while three (60 %) were converted to open cholecystectomy.

Conclusion

Simultaneous cholecystectomy during liver hydatid cyst surgery may prevent difficulties associated with treating symptoms related to subsequent cholelithiasis.

Introduction

The rat model of 70 % partial hepatectomy (PH) is commonly used to investigate liver regeneration processes. The aim of this study was to explore the dynamics of hepatic lipid accumulation and its correlation with the proliferation response during the entire regeneration phase after 70 % PH in rats.

Methods

Sixty-four rats underwent 70 % PH and were randomly divided into eight groups for evaluation on post-operative day (POD) 1 to 8. Hepatocyte volume, relative lipid content, and lipid volume per hepatocyte were assessed by stereological analysis.
Results: Lipid volume per hepatocyte reached its peak on POD 1 and POD 2, with mean values of 2895 μm3 (95 % CI: 1756–4034 μm3) and 3090 μm3 (95 % CI: 2277–3903 μm3), respectively. A marked decline was observed by POD 4, with a mean of 1323 μm3 (95 % CI: 985–1741 μm3), which continued through POD 5, reaching 619 μm3 (95 % CI: 136–1102 μm3). From POD 5 onwards, lipid volume remained consistently low, with no significant differences detected between POD 5 and POD 8.

Conclusion

Lipid accumulation and proliferation peak and decline concurrently, suggesting a strong correlation.

Pancreatic ductal adenocarcinoma (PDAC) is predicted to become the second leading cause of death in 2030 and it is characterized by poor prognosis, recurrence and resistance to therapies. Several factors contribute to the complexity of this disease, among those the invasion of nerves by PDAC cells. This condition, defined as perineural invasion (PNI), is responsible of PDAC progression and pain generation. To date, PNI emerges as a hallmark feature of PDAC, showing the same oncological weight of lymph node metastasis in terms of prognosis. Targeting PNI could help improve prognosis and pain relief in PDAC patients. Only recently, a severity scoring system has been proposed to quantify PNI in histological samples although prospective validation and standardization are strongly advocated. More information about peripancreatic soft tissue infiltration and a “true” curative surgery could be found in understanding the molecular mechanisms of PNI. The incorporation of PNI markers for grading mesopancreas and retroperitoneal invasion is required to overcome current limitations of the histological workup. We discuss the modern understanding of PNI in PDAC, and the state of the art in clinical setting. Although there are still a lot to learn about PDAC, PNI represents one of the biological detonators and an important focus of future research.

Background

We aimed to evaluate the impact of tumor deposit (TD) count on cancer-specific survival (CSS) and disease-free survival (DFS) in stage III colorectal cancer (CRC) patients stratified by T and N staging, and further explore its impact on chemotherapy effect.

Method

We determined the optimal TD cut-off value for stage III CRC patients from the SEER database utilizing X-tile analysis, and retrospectively analyzed the clinicopathological data of 443 patients from the First Affiliated Hospital of Wenzhou Medical University from 2019 to 2020. Chi-square (χ2) tests compared categorical variables. Kaplan–Meier assessed CSS and DFS. Cox regression model evaluated prognostic factors on CSS and DFS.

Results

2TD is the optimal cutoff value for prognosis in Stage III CRC, in the low-risk group (T1-T3 and N1), ≥3TD patients faced higher cancer-specific mortality (HR = 3.445, 95%CI = 1.254–9.465, P = 0.017) and recurrence risks (HR = 1.934, 95%CI = 1.095–3.416, P = 0.024) vs. 1-2TD, while 1-2TD and no-TD patients showed no difference in survival. In the high-risk group (T4 or N2), both ≥3TD and 1-2TD patients had poor prognosis. Chemotherapy reduced cancer-specific mortality in both groups (1-2TD: HR = 0.347, 95%CI = 0.138–0.870, P = 0.024; ≥3TD: HR = 0.272, 95%CI = 0.077–0.960, P = 0.043) but did not significantly improve recurrence risk (1-2TD: P = 0.177; ≥3TD: P = 0.058).

Conclusion

TD indicates poor prognosis in stage III CRC, with ≥3 TD significantly worsening survival, yet the prognosis remains poor in TD-positive patients with high-risk (T4 or N2) regardless of TD count. Moreover, TD count does not influence chemotherapy's mortality benefit.

Background

Left-handedness is often perceived as a disadvantage in surgical training due to the predominance of right-handed instruments and right-handed mentors. Whether this affects the performance of left-handed trainees remains unclear. This study aims to compare the suturing proficiency of left-handed and right-handed novice learners when taught by right-handed instructors using right-handed tools.

Methods

A prospective, non-randomized, non-inferiority trial was conducted among students without prior suturing experience, divided by handedness. Participants underwent a teaching session on simple interrupted suturing using right-handed instruments and were assessed using a validated ten-item checklist. Secondary outcomes included satisfaction and were assessed via subjective questionnaires.

Results

Among 129 participants (86 right-handed, 43 left-handed), no significant difference in suturing performance was observed between groups. However, left-handed participants reported subjective difficulties using right-handed instruments, and instructors noted challenges teaching them.

Conclusion

Handedness does not impact the final outcome of basic surgical skills teaching. However, left-handed students may perceive more challenges due to right-handed tools and techniques. Tailoring teaching strategies and providing hand-specific tools may improve their learning experience.

This study explores the motivations for attendance, methods of conference promotion, and key considerations in implementing a hybrid conference for global surgery education among medical students and trainee doctors. The InciSion UK Global Surgery Conference 2023, held in London, provided a unique platform combining in-person and virtual participation. Pre- and post-conference surveys collected qualitative and quantitative data from 640 and 794 respondents, respectively. Professional development (83.4 %) and learning about global surgery (70.8 %) were primary motivators for attendance. Confidence in global surgery significantly increased post-conference (mean score: 4.21 vs. 2.82, p < 0.001). Social media was the most effective promotional tool, introducing 38.4 % of attendees to the event. Participants highlighted the diversity and quality of talks as strengths, while technical issues were a challenge. Future conferences should enhance technical infrastructure and interactive engagement for virtual attendees. The hybrid model proves effective in broadening access to global surgery education and fostering collaboration across diverse geographical regions.

Background

Performing laparoscopic suturing requires quality education. Differences in instruction according to trainer surgeon specialty could affect trainee skill acquisition. This study compares the focus of feedback between Upper gastrointestinal (UGI) specialists and Colorectal (CR) specialists.

Methods

A 13-year postgraduate trainee received online feedback for two laparoscopic suturing procedures videos of “low” and “high” difficulty from 16 surgeons (UGI = 8, CR = 8) who are specialists in laparoscopic surgery and qualified by the Endoscopic Surgical Skill Qualification System of the Japan Society for Endoscopic Surgery. The number of feedback comments was compared between specialist groups for grasping the needle, needle driving, knot tying preparation, and knot tying. Both groups were also surveyed regarding suturing procedures.

Results

The UGI group had significantly more feedback comment varieties for knot tying preparation during the “high” difficulty video (UGI 4.0 ± 2.1 (mean ± SD), CR 1.9 ± 1.4, p < 0.05). According to questionnaire results, the UGI group performed suturing more routinely than the CR group, was more confident, and less stressed about the procedure.

Conclusion

In feedback for laparoscopic suturing videos, the UGI group focused more on the preparatory stage for knot tying than the CR group. This indicates that comment focus differs according to specialty, suggesting that instruction from trainers of multiple specialties is optimal.

Key message

In this study, it was shown that the focus of feedback on laparoscopic suturing procedures differs according to the surgeon's subspecialty. These insights could have important implications for optimizing laparoscopic training programs.

Background

Allogenic kidney transplantation has been the gold standard treatment for end-stage renal disease. In the research setting, rat models are widely utilized to refine surgical techniques and enhance graft viability. One critical factor affecting transplantation outcomes is the efficiency of the venous anastomosis. This study evaluates the utility of a microvascular coupling device for venous anastomosis in a rat kidney transplantation model.

Material and methods

Experimental allogenic kidney transplantations were conducted in male Brown Norway rats (n = 10) as donors and Lewis rats as recipients (n = 17), housed according to institutional guidelines. A microvascular coupling device was used for renal venous anastomosis, and creatinine levels were measured postoperatively to assess kidney function. Procedure times, ischemia duration, and postoperative complications were recorded and analyzed.

Results

The venous anastomosis time averaged 6.6 ± 2.2 min. Total ischemia time averaged 42.4 ± 4.9 min. Early postoperative serum creatinine levels were slightly elevated about references thresholds, which normalized by postoperative day 3. Four animals died after successful transplantation due to urethral complications and postrenal failure (23.5 %). Other postoperative mortality was primarily linked to complications unrelated to thrombosis (n = 3, 17.6 %).

Conclusion

The use of a microvascular coupling device for venous anastomosis in rat kidney transplantation significantly reduces procedure time and ischemia duration, contributing to more consistent graft outcomes. The simplification of the venous anastomosis process and reduced operative time justify the use of coupling devices. This technique holds promise for advancing preclinical transplant research and improving reproducibility in microsurgical procedures.

Objective

Explore the perceptions and attitudes of medical students regarding their education in opioid prescribing for pain management.

Design

Three focus group discussions elicited open-ended, information-rich responses from medical students attending multiple institutions. Thematic analysis identified common themes from focus group transcript data.

Setting

Rollins School of Public Health at Emory University, Atlanta, Georgia, USA.

Participants

Medical students (n = 12) from four medical schools in the United States.

Results

Focus group participants indicated they experienced changes in their perceptions and attitudes about opioids during their time in medical school, gradually recognizing the importance of treating pain while avoiding overprescribing and opioid-related harms. Discussions revealed that the curriculum on opioid medications and their prescription in medical school is limited and varied, with most opportunities for learning arising during preclinical years. The quantity and quality of the opioid-related education experienced by participants during medical school impacted their perceived knowledge about opioids and, consequently, their confidence in treating pain. Participants noted that important gaps in their knowledge about opioid prescribing persist, which may influence their future prescribing habits. While participants understood they had insufficient knowledge about opioid prescribing, they anticipated there would be additional learning during their residency programs.

Conclusions

There is room for improvement for medical school instruction on the safe and effective use of opioids for pain management in the United States. Medical students themselves have expressed a desire for enhanced opioid education. Strengthening opioid education has implications across various healthcare environments, particularly in settings with prevalent opioid prescribing.
