Urinary incontinence is a common complication following robot-assisted radical prostatectomy (RARP). Urethral length has been identified as a factor affecting postoperative continence recovery. In this meta-analysis, we examined the association between use of the maximal urethral length preservation (MULP) technique and postoperative urinary continence in patients undergoing RARP. We conducted a comprehensive search of PubMed, Web of Science, Embase, and the Cochrane Library up to December 31, 2023. The quality of the literature was assessed using the Newcastle-Ottawa Scale. A random-effects meta-analysis was performed to synthesize data and calculate the odds ratio (OR) from eligible studies on continence and MULP. Six studies involving 1869 patients met the eligibility criteria. MULP was positively associated with both early continence (1 month after RARP; Z = 3.62, P = 0.003, OR = 3.10, 95% confidence interval [CI]: 1.68-5.73) and late continence (12 months after RARP; Z = 2.34, P = 0.019, OR = 2.10, 95% CI: 1.13-3.90). Oncological outcomes indicated that MULP did not increase the overall positive surgical margin rate or the positive surgical margin status at the prostate apex (both P > 0.05). In conclusion, the use of the MULP technique in RARP significantly improved both early and late postoperative continence outcomes without compromising oncological outcomes.

Tianhe procedure^® is a functional sphincter-preserving surgical approach developed for rectal cancer patients following radiotherapy. This technique involves extended proximal resection of the colon beyond the pelvic cavity, followed by anastomosis of the non-irradiated proximal colon to the distal rectum or anal canal. This strategy aims to reduce the incidence of anastomotic complications and postoperative bowel dysfunction. However, there is currently a lack of standardized practice guideline for implementing Tianhe procedure^® in China. Therefore, the Chinese Radiation Intestinal Injury Research Group, the Colorectal Surgery Group of Surgery Branch of the Chinese Medical Association, the Anorectal Branch of Chinese Medical Doctor Association, the Colorectal Cancer Committee of the Chinese Medical Doctor Association, and the Colorectal Cancer Committee of China Anti-cancer Association, and the Gastrointestinal Surgical Branch of Guangdong Medical Doctor Association, have jointly convened a panel of national experts to discuss and establish this standardized surgical procedure. This standard, based on the latest evidence from literature, research advancements, and expert experience, focuses on key aspects of the Tianhe procedure^®, including its precise definition, indications, critical procedural steps, postoperative complications, and functional rehabilitation strategies. It aims to promote standardized implementation and broader clinical adoption of this innovative surgical technique.

Adrenal gland trauma is a rare phenomenon, due to the small size and retroperitoneal location of the organ. The majority of adrenal gland trauma is due to blunt force injury and is only rarely encountered due to the penetrating mechanisms. A 20-year-old male sustained a gunshot wound to the left abdomen. Upon exploration, he was found to have a through and through injury to the left adrenal gland, among other injuries. Injury to the adrenal gland due to penetrating trauma is exceptionally rare. The principles of management are to control bleeding from the gland with debridement and hemostasis rather than attempt to resect the entire organ. The management of a penetrating injury to the adrenal gland is straightforward and should not be a contributor to a patient's morbidity or mortality.

Objective: To explore the strategies of preserving urinary continence in transurethral plasmakinetic enucleation of the prostate (PKEP) for benign prostate hyperplasia (BPH). METHODS: We treated 65 BPH patients by PKEP with preservation of urinary continence (UC-PKEP), which involved protection of the external urethral sphincter in the beginning of surgery, proper preservation of the anterior lobe of the prostate to protect the internal urethral sphincter in the middle, and preservation of the integrity of the bladder neck towards the end. We compared the postoperative status of urinary continence of the patients with that of the 54 BPH cases treated by complete plasmakinetic enucleation of the prostate (Com-PKEP). RESULTS: All the operations were performed successfully with the urinary catheters removed at 5 days after surgery. In comparison with Com-PKEP, UC-PKEP achieved evidently lower incidence rates of urinary incontinence at 24 hours (31.49% vs 13.85%, P <0.05), 1 week (18.52% vs 4.62%, P <0.05), 2 weeks (14.81% vs 3.08%, P <0.05), 1 month (3.70% vs 1.54%, P >0.05), and 3 months (3.70% vs 0%, P >0.05) after catheter removal. Compared with the baseline, the maximum urinary flow rate (Qmax) was significantly improved postoperatively in both the Com-PKEP (［7.43 ± 3.26］ vs ［20.58 ± 3.22］ ml, P <0.05) and the UC-PKEP group (［8.04 ± 2.28］ vs ［20.66 ± 3.08］ ml, P <0.05). CONCLUSIONS Transurethral PKEP is a safe and effective method for the management of BPH, during which the strategies of avoiding blunt or sharp damage to the external urethral sphincter in the beginning, properly preserving the anterior lobe of the prostate in the middle and preserving the integrity of the bladder neck towards the end may help to achieve rapid recovery of urinary continence.

Microsurgical longitudinal intussusception vasoepididymostomy (LIVE) has been widely used to treat epididymal obstructive azoospermia since 2004. Although the deferential vasculature plays an important role in supplying blood to the testis and epididymis, little attention has been paid to the potential benefits of sparing the deferential vessels during the anastomosis in LIVE. This study aimed to evaluate the efficacy and safety of deferential vessel-sparing LIVE in humans. From December 2013 to December 2015, 69 azoospermic men with epididymal obstruction due to a genital infection, trauma, or idiopathic factors underwent deferential vessel-sparing LIVE in the First Affiliated Hospital of Sun Yat-Sen University, Guangzhou, China. The outcomes of these patients were analyzed retrospectively. The mean age was 31.1 years for men and 28.3 years for their partners. Fifty-nine (85.5%, 59/69) men were followed up after surgery for approximately 16 months. Patency was noted and confirmed by semen analysis (>10 000 sperm/ml) in 83.1% (49/59) of men. The natural pregnancy rate was 40.7% (24/59) by the end of the study, with 87.5% (21/24) of these natural pregnancies achieved within 12 months after surgery. No severe adverse events or complications were observed. In this study, we present a novel technique for sparing the deferential vessels during LIVE. The preliminary outcomes show this technique to be safe with favorable patency and pregnancy rates.

PURPOSE: The purpose of this study was to compare the clinical outcomes of arthroscopic anatomical double bundle (DB) anterior cruciate ligament (ACL) reconstruction with either selective anteromedial (AM) or posterolateral (PL) bundle reconstruction while preserving a relatively healthy ACL bundle. MATERIALS AND METHODS: The authors evaluated 98 patients with a mean follow-up of 30.8±4.0 months who had undergone DB or selective bundle ACL reconstructions. Of these, 34 cases underwent DB ACL reconstruction (group A), 34 underwent selective AM bundle reconstruction (group B), and 30 underwent selective PL bundle reconstructions (group C). These groups were compared with respect to Lysholm and International Knee Documentation Committee (IKDC) score, side-to-side differences of anterior laxity measured by KT-2000 arthrometer at 30 lbs, and stress radiography and Lachman and pivot shift test results. Pre- and post-operative data were objectively evaluated using a statistical approach. RESULTS: The preoperative anterior instability measured by manual stress radiography at 90° of knee flexion in group A was significantly greater than that in groups B and C (all p<0.001). At last follow-up, mean side-to-side instrumented laxities measured by the KT-2000 and manual stress radiography were significantly improved from preoperative data in all groups (all p<0.001). There were no significant differences between the three groups in anterior instability measured by KT-2000 arthrometer, pivot shift, or functional scores. CONCLUSION: Selective bundle reconstruction in partial ACL tears offers comparable clinical results to DB reconstruction in complete ACL tears.

INTRODUCTIONThe use of laparoscopic distal pancreatectomy (LDP) has increased worldwide due to the reported advantages associated with this minimally invasive procedure. However, widespread adoption is hindered by its technical complexity. Robotic distal pancreatectomy (RDP) was introduced to overcome this limitation, but worldwide experience with RDP is still lacking. There is presently evidence that RDP is associated with decreased conversion rate and increased splenic preservation as compared to LDP.

METHODSWe conducted a prospective study on our initial experience with robotic spleen-saving, vessel-preserving distal pancreatectomy (SSVP-DP) between July 2013 and April 2014.

RESULTSThree consecutive patients underwent attempted robotic SSVP-DP. The indications were a 2.1-cm indeterminate cystic neoplasm, 4.5-cm solid pseudopapillary neoplasm and 1.2-cm pancreatic neuroendocrine tumour. For all three patients, the procedure was completed without conversion, and the spleen, with its main vessels, was successfully conserved. The median total operation time, blood loss and postoperative stay were 350 (range 300-540) minutes, 200 (range 50-300) mL and 7 (range 6-14) days, respectively. Two patients had minor Clavien-Dindo Grade I complications (one Grade A pancreatic fistula and one postoperative ileus). One patient had a Clavien-Dindo Grade IIIa complication (Grade B pancreatic fistula requiring percutaneous drainage). All patients were well at the time of reporting after at least six months of follow-up.

CONCLUSIONOur preliminary experience with robotic SSVP-DP confirmed the feasibility of the procedure.

Surgical treatment for rectal cancer has changed radically in recent years since the introduction of the principle of total mesorectal excision (TME) and technique of laparoscopic approach. The emphasis of management for vessels in laparoscopic TME surgery for rectal cancer is mainly focused on the inferior mesenteric artery (IMA) and its branches. Two alternatives of the level to execute the IMA are high ligation(without preservation of left colic artery, LCA) and low ligation (with preservation of LCA). In this article, we review the latest literature from China and foreign countries concerning this issue, and combine with our own experience to investigate the effect of LCA preserving on anastomotic leakage and operation time, which may provide a reference for proper choice of the management of IMA in rectal cancer surgery.

Compared with distal gastrectomy, pylorus-preserving gastrectomy is less invasive which can decrease incidence of dumping syndrome, diarrhea and body weight lost, cholecystitis and gallstone, reflux gastritis and esophagitis and remnant gastric cancer. Based on new Japanese Gastric Cancer Treatment Guideline and new progression in the world, we give a review mainly basic characteristics, indications, operation details and short- and long-time outcomes after pylorus-preserving gastrectomy.

Under the premise of radical resection in the treatment, it is of great significance to preserve partial gastric function so that the early gastric cancer (EGC) patients' postoperative quality of life (QOL) can be improved. In the patients with EGC in the upper third of the stomach, the emphasis is on the prevention of reflux esophagitis caused by bile and gastric juice reflux. Pylorus-preserving gastrectomy (PPG) is applicable to the patients with EGC in the middle third of the stomach. In the patients with EGC in the lower third of the stomach, distal gastrectomy (DG) is performed in general. Various anastomosis ways are applied to reduce the negative impact of pylorus resection after DG. Furthermore, it should also be considered that reasonable vagal nerves preservation and lymph node dissection are both important for function preserving gastrectomy of EGC. Rational use of laparoscopy-assisted gastrectomy has advantages of lower invasiveness, faster recovery, etc. And the amplification effect of laparoscope can contribute to preserving nerves and gastric function.
