Article Abstract
Background: It is well known that conventional splenectomy, which requires careful handling and ligation of tissue of the splenic hilum, can easily cause complications such as splenic fever and pancreatic fistula. Here, we use the technique of dissection of the secondary branches of the splenic pedicle to handle the hilum in the portal hypertension patients who are subjected to splenectomy.
Methods: We retrospectively compared and analyzed the complications, postoperative hospital stay, operative time, and occurrence of hemorrhage in 121 patients with portal hypertension undergoing splenectomy and devascularization of the gastric cardia from January 1999 to December 2007. The selected cases consisted of 51 patients undergoing conventional splenectomy and 70 patients undergoing dissection of secondary branches of the splenic pedicle. In addition, we analyzed the relationship between size of the spleen and occurrence of complications.
Results: The incidence of pancreatic fistula and splenic fever (0/70 and 9/70) was lower in patients undergoing dissection of secondary branches of the splenic pedicle as compared with that of the conventional group (5/51 and 18/51 respectively). In addition, there was no significant difference in operative time and volume of blood loss between two groups. The spleen thickness of those patients who had pancreatic fistula and splenic fever was significantly greater than those without complications.
Conclusions: These results indicate that dissection of secondary branches of the splenic pedicle in portal hypertension patients undergoing splenectomy can decrease the incidence of splenic fever and pancreatic fistula, and shorten the postoperative hospital stay, especially in the patients with a large spleen. So dissection of secondary branches of the splenic pedicle is a valuable technique for splenectomy.

Impact of D3 lymph node dissection extent on postoperative bowel function and nutritional status in right-sided colon cancer: a prospective randomized controlled trial.
Int J Surg
September 2025
Department of Gastrointestinal Surgery, Shandong Provincial Hospital Affiliated to Shandong First Medical University, Jinan, Shandong, China.
Aim And Background: This study investigates the impact of D3 lymph node dissection extent on postoperative bowel function and nutritional status in patients undergoing radical surgery for right-sided colon cancer. Given that postoperative diarrhea can significantly affect the quality of life, we examined whether dissection boundaries influence these outcomes.
Methods: This was a prospective, randomized controlled trial conducted at a high-volume tertiary hospital.

Background: Metastases in the lateral pelvic lymph nodes or mesenteric lymph nodes represent distinct categories of mid-low rectal cancer. This study investigated the patterns of mesenteric and lateral pelvic lymph node metastases in mid-low rectal cancer; the survival benefit of postoperative treatment was also analysed in these groups.
Methods: This retrospective multicentre study included consecutive patients with mid-low rectal cancer who underwent total mesorectal excision with lateral pelvic lymph node dissection in three Chinese institutions between 2012 and 2020.
Management of the dissected aortic root in young patients: A propensity score-matched analysis of mechanical versus bioprosthetic aortic root replacement.

Division of Cardiovascular Surgery, Department of Surgery, University of Pennsylvania, Philadelphia, Pa.
Objective: Valve selection in acute type A aortic dissection (ATAAD) requiring aortic root replacement is challenging given the clinical acuity, unknown patient preferences, risk of surgical bleeding, and limited life expectancy. We sought to identify long-term outcomes of mechanical versus bioprosthetic aortic root replacement in young patients with ATAAD.
Methods: Retrospective review of our institution's database of ATAAD was conducted to identify patients aged 65 years and younger who underwent mechanical Bentall (mech-Bentall) or bioprosthetic Bentall (bio-Bentall) for ATAAD from 2002 to 2022.

Background: Calcium pyrophosphate dihydrate (CPPD) deposition disease at the craniocervical junction (CCJ) typically presents with a retro-odontoid pseudotumor. Here, the authors report a case of CPPD-induced basilar impression, causing vertebral artery (VA) dissection and hemorrhage.
Observations: A 65-year-old male presented with worsening chronic cervicalgia, occipital headaches, and unstable tandem gait.
Multimodal ultrasonographic and clinicopathological model for predicting high-volume lymph node metastasis in cN0 papillary thyroid carcinoma.

Background: Given the challenge in preoperative diagnosis of high-volume lymph node metastasis (HVLNM) in clinical practice, we constructed and externally validated a comprehensive predictive model that integrated conventional ultrasound characteristics, contrast-enhanced ultrasound (CEUS) parameters, BRAFmutation, and clinicopathological data for HVLNM in clinically lymph node-negative (cN0) papillary thyroid carcinoma (PTC).
Methods: Totally, 126 clinically lymph node-negative (cN0) PTC patients who underwent subtotal or total thyroidectomy and accompanied with prophylactic cervical lymph node dissection between December 2022 and December 2024 were enrolled in this retrospective study, and an additional 47 cN0 PTC patients included for the external validation cohort. Univariate and multivariate analysis were performed to identify the independent risk factors for HVLNM, and a binary logistic regression equation and relevant nomogram was constructed to predict the risk about HVLNM.
