ABSTRACT
OBJECTIVE: The da Vinci SP Surgical System (SP) received regulatory approval for use in gynecological surgeries in Japan in 2023. Given the advantages of the precision of a robot, less pain, and the cosmesis of single-port surgery, the da Vinci SP is expected to be further used for minimally invasive surgeries. To the best of our knowledge, this is the first report of the use of SP for the treatment of rectal endometriosis with segmental bowel resection. SETTING: An urban general hospital. Stepwise demonstration of the technique with narrated video footage. PARTICIPANTS: The patient was a 46-year-old woman presented with chronic pelvic pain, pain on defecation and constipation. Magnetic resonance imaging showed uterine large fibroid, left ovarian endometrioma, and 38mm of rectal endometriosis, with complete cul-de-sac obliteration. INTERVENTIONS: We made a 30-mm vertical incision at the umbilicus, then placed the access port, and inserted three articulating instruments and a camera. An assistant port was placed in the right lower quadrant for using the linear stapler. The surgical steps were completely identical to conventional multiport laparoscopic robotic surgery. This suggests that conventional laparoscopic or robotic skills are highly transferrable to SP. SP offer several advantages, including high-resolution three-dimensional visualization, articulating instruments, and improved dexterity and range of motion. In addition, the umbilical access port was particularly useful for proximal bowel resection, specimen retrieval, and anvil positioning during bowel resection. The total operative time was 216 minutes. The estimated blood loss was 100 ml without any complications. The uterine weight was 800 g. The postoperative course was uneventful, with no perioperative complications, including no postoperative bladder dysfunction or low anterior resection syndrome [1, 2]. CONCLUSION: The use of SP with the access port for segmental bowel resection for rectal endometriosis is technically safe and feasible, with good cosmesis and less pain.
ABSTRACT
AIM: A minimally invasive surgery (MIS) extraperitoneal (XP) approach to left-sided colorectal resection utilizing the laparoscopic approach has recently been shown to be safe and feasible and to have potential advantages over the transperitoneal approach, especially in high-risk surgical patients. The aim of this article is to provide a first cadaveric demonstration of the use of a single-port robotic platform in performing XP low anterior resection by MIS. METHOD: A single-port robotic platform (DaVinci®SP™) was used to perform XP single-port low anterior resection in two cadavers with body mass indexes (BMIs) of 19 and 40 kg/m2. RESULTS: The single-port robotic platform with versatile arms was successfully used to perform a complete low anterior resection with splenic flexure mobilization and total mesorectal excision through a single port. CONCLUSIONS: A single-port robotic platform enhances complete XP dissection in the supine patient in extreme BMI ranges. Clinical studies are necessary to confirm these findings.
ABSTRACT
Background and objective: The purpose-built SHURUI single-port (SP) robotic platform has recently been introduced for several procedures in urology, general surgery, and gynecology. However, comparative evidence on its performance in relation to earlier models such as the da Vinci SP is lacking. Our aim was to compare the step-by-step techniques and 1-yr outcomes for radical prostatectomy (RP) between the SHURUI SP and da Vinci SP robots. Methods: Data were retrieved from two prospectively maintained databases. The SHURUI SP robot was used to perform RP in 34 patients in China (September 2021 to August 2022); the da Vinci SP robot was used to perform 100 consecutive RP cases in the USA (June 2019 to October 2020). A comparative analysis was conducted before and after 1:1 propensity score matching for age, body mass index, American Urological Association symptom score, prostate size, prostate-specific antigen (PSA) levels, biopsy grade group, and D'Amico risk group. Intraoperative performance and short-term oncological and continence outcomes were compared between the groups. Biochemical recurrence was defined as two consecutive postoperative PSA levels >0.2 ng/ml. Continence was defined as full recovery of urinary control without the use of pads. The Kaplan-Meier method was used to estimate continence recovery curves, and a log-rank test for trend was used to detect ordered differences in continence recovery between the SHURUI SP and da Vinci SP groups after surgery. Key findings and limitations: For the matched SHURUI and da Vinci groups, median age (69 vs 69 yr), median PSA (8.4 vs 7.1 ng/ml), and the proportion of patients with low-risk (33.3% vs 29.6%), intermediate-risk (66.7% vs 63%), and high-risk disease (0% vs 7.4%) were comparable (all p > 0.05). All surgeries were successfully accomplished without conversion. A higher percentage of cases in the SHURUI group involved extraperitoneal access (81.5% vs 0%; p < 0.001) and a pure SP approach (25.9% vs 0%; p = 0.01), while a higher percentage of cases in the da Vinci group had nerve-sparing surgery. The median total operative (215 vs 110 min; p < 0.001) and median console time (162 vs 75 min; p < 0.001) were significantly longer in the SHURUI group. No intraoperative or major postoperative complications were observed in either group. Rates of positive surgical margins (18.5% vs 14.8%; p = 1.0) and extraprostatic extension (14.8% vs 29.6%; p = 0.19) were similar. At median follow-up of 13.5 versus 15.9 mo, none of the patients had experienced biochemical recurrence. At 1 yr after surgery, the continence rate was 96.3% in both groups. Conclusions: Despite differences in driving mechanisms between the two SP robotic systems, RP can be performed safely and effectively with the SHURUI RP robot during the initial learning phase, with similar short-term oncological and continence outcomes to those with the da Vinci SP robot. Patient summary: We compared two surgical robots (SHURUI SP and da Vinci SP) used to perform robotic surgery to remove the prostate through a single keyhole incision instead of multiple incisions. Our results show comparable technology and similar surgical and short-term cancer control outcomes for the two robots.
ABSTRACT
Objective: This study assesses the effectiveness and safety of single-port laparoscopic myomectomy (SPLM) versus conventional laparoscopic myomectomy (CLM). Methods: We conducted a retrospective case-control study at a university tertiary hospital, involving 262 patients treated from July 2020 to December 2022. Participants were divided into two groups: 132 underwent SPLM and 130 underwent CLM. Results: The two groups were comparable in terms of age, body mass index, parity, delivery history, preoperative anemia, number of myomas, and size of the largest myoma. The SPLM group showed a significant reduction in operation time (average 93 min) and estimated blood loss (average 50 ml) compared to the CLM group (average 118.5 min and 100 ml, respectively). Subgroup analysis based on the size, location, and number of myomas further highlighted the advantages of SPLM, particularly for patients with large (diameter ≥8 cm) or multiple myomas (number ≥4). Patient satisfaction was also notably higher in the SPLM group. Conclusions: Single-port laparoscopic myomectomy offers a highly effective, safer, and patient-preferred option for the surgical management of fibroids, especially in cases of large or multiple myomas. These findings suggest that SPLM could become the preferred surgical approach for complex fibroid cases, promising less trauma and quicker recovery for patients.
ABSTRACT
BACKGROUND: Transanal minimally invasive surgery (TAMIS) is widely used for rectal lesion excision. Robot-assisted TA TAMIS (R-TAMIS) may improve surgical ergonomics. The introduction of the da Vinci Single-Port (SP) robot, designed for endoluminal surgery, has brought new possibilities. Our primary objective herein was to assess the technical and oncological feasibility and efficacy of Single-port robotic TAMIS (SPR-TAMIS) in rectal cancer excision. The secondary objective was to analyze the perioperative outcomes. MATERIALS AND METHODS: We included 14 consecutive patients with rectal cancer who underwent SPR-TAMIS between April 2021 and February 2023. Patient data, surgical details, and clinical outcome data were collected to assess the safety and feasibility of SPR-TAMIS. RESULTS: The median participant age was 72 years, and full-thickness excision was performed without specimen fragmentation in all cases. The median tumor diameter was 2.7 cm, positioned between 10 cm proximally and 7 cm distally from the anal verge. Negative margins were achieved in 93% of cases, with one case requiring further resection. The median operative time was 175 min, and the median hospital stay was 5 days. No intraoperative conversion from SPR-TAMIS to laparoscopic or conventional transanal excision was required. No mortalities or major postoperative complications occurred; however, one patient (7.1%) experienced minor morbidity manifesting as wound dehiscence (Clavien-Dindo grade I). No recurrence was observed during the 24-month follow-up. CONCLUSIONS: In our early experience, SPR-TAMIS is a safe and feasible surgery for selected early stage rectal cancers, offering enhanced visualization and stable maneuverability transanally. This platform may have potential advantages for the excision of larger or more proximal lesions.
ABSTRACT
BACKGROUND: The da Vinci Single-Port Robot System (DVSP) allows three robotic instruments and an articulated scope to be inserted through a single small incision. It received FDA approval in 2014 and was first introduced in 2018. The aim of this new system was to overcome the limitations of single-incision laparoscopic and robotic surgery. Since then, it has been approved for use only for urologic and transoral surgeries in some countries. It has been used as part of experimental protocols in general surgery. OBJECTIVE: By obtaining the CE mark at the end of January 2024, DVSP will soon enter the European market. This review aims to comprehensively describe the applications of DVSP in general surgery. DESIGN: A search of PubMed, Embase, and Ebsco databases up to March 2024 was conducted, with registration in PROSPERO (CRD42024536430), following the preferred reporting items for Systematic reviews and Meta-analyses for scoping review (PRISMA-Scr) guidelines. All the studies about the use of DVSP in general surgery were included. RESULTS: Fifty-six studies were included. The following surgical areas of use were identified: transabdominal and transanal colorectal, cholecystectomy, abdominal wall repair, upper gastroesophageal tract, liver, pancreas, breast, and thyroid surgery. The reported surgical and short-term outcomes are promising; a wide range of procedures have been performed safely. Some groups have found advantages, such as faster discharge, shorter operative time, and less postoperative pain compared to multiport robotic surgery. CONCLUSION: Five years after its initial clinical applications, the use of the DVSP in general surgery procedures has demonstrated feasibility and safety. Hernia repair, cholecystectomy, and colorectal surgery emerge as the most frequently conducted interventions with this robotic system. Nevertheless, there is anticipation for further studies with larger sample sizes and extended follow-up periods to provide more comprehensive insights and data on the long-term outcomes, including the incidence of incisional hernia.
ABSTRACT
The safety and efficacy of single-port and multi-port robot-assisted partial nephrectomy (SP-RAPN and MP-RAPN, respectively) were assessed for treating partial nephrectomy in this study. A systematic review of PubMed, Cochrane Library, and Web of Science databases was conducted up to June 2024 to compare studies on SP-RAPN and MP-RAPN. Primary outcomes included perioperative results, complications, and oncological outcomes. Eight studies involving 1014 patients were analyzed. For binary outcomes, comparisons were performed using odds ratios (OR), and for continuous variables, weighted mean differences (WMD) with 95% confidence intervals (CI). The search failed to discover significant meaningful variations in operating times (p = 0.54), off-clamp procedure (P = 0.36), blood loss (p = 0.31), positive surgical margins (PSMs) (p = 0.78), or major complications (Clavien-Dindo grade ≥ 3) (p = 0.68) between SP-RAPN and MP-RAPN. However, shorter hospital stays (WMD - 0.26 days, 95% CI - 0.36 to - 0.15; p < 0.00001) and longer warm ischemia times (WIT) (WMD 3.13 min, 95% CI 0.81-5.46; p = 0.008) were related to SP-RAPN, and higher transfusion rate (OR 2.99, 95% CI 1.31-6.80; p = 0.009) compared to MP-RAPN. SP-RAPN performed better in terms of hospital stay but had slightly higher rates of transfusion, off-clamp procedures, and warm ischemia time (WIT) compared to MP-RAPN. As an emerging technology, preliminary research suggests that SP-RAPN is a feasible and safe method for carrying out a nephrectomy partial. However, compared to MP-RAPN, it shows inferior outcomes regarding (WIT) and transfusion rates.

Objectives: Surgery through a single port may be less painful because access is supplied by 1 intercostal nerve or more painful because multiple instruments are used in 1 port. We analyzed data collected from the video-assisted thoracoscopic surgery group of a randomized controlled trial to compare differences in pain up to 1 year. Methods: Groups were compared in a prespecified exploratory analysis using direct (regression) and indirect comparison (difference with respect to thoracotomy). In-hospital visual analogue scale pain scores were used, and analgesic ratios were calculated. After discharge, pain was evaluated using European Organization for Research and Treatment of Cancer Quality of Life Questionnaires-Core 30 scores up to 1 year. Results: From July 2015 to February 2019, we randomized 503 participants. After excluding 50 participants who did not receive lobectomy, surgery was performed using a single port in 42 participants (predominately by a single surgeon), multiple ports in 166 participants, and thoracotomy in 245 participants. No differences were observed in-hospital between single- and multiple-port video-assisted thoracoscopic surgery when modeled using a direct comparison, mean difference of -0.24 (95% CI, -1.06 to 0.58) or indirect comparison, mean difference of -0.33 (-1.16 to 0.51). Mean analgesic ratio (single/multiple port) was 0.75 (0.64 to 0.87) for direct comparison and 0.90 (0.64 to 1.25) for indirect comparison. After discharge, pain for single-port video-assisted thoracoscopic surgery was lower than for multiple-port video-assisted thoracoscopic surgery (first 3 months), and corresponding physical function was higher up to 12 months. Conclusions: There were no consistent differences for in-hospital pain when lobectomy was undertaken using 1 or multiple ports. However, better pain scores and physical function were observed for single-port surgery after discharge.
ABSTRACT
BACKGROUND: The adoption of Robotic Pancreaticoduodenectomy (RPD) is increasing globally. Meanwhile, reduced-port RPD (RPRPD) remains uncommon, requiring robot-specific techniques not possible with laparoscopy. We introduce a unique RPRPD technique optimizing surgical field exposure. METHODS: Our RPRPD utilizes a single-site plus-two ports technique, facilitated by a single-port platform through a 5-cm incision. The configuration of robotic arms (arm1, arm2, arm3, and arm4) were strategically designed for optimal procedural efficiency, with the arms2 and arm3, alongside the assistant trocar, mounted on the single-port platform, while the arms1 and arm4 were positioned laterally across the abdomen. Drainage was established via channels created at the arm1 and arm4 insertion sites. A "gooseneck traction" was principally employed with the robotic instrument to prop up the specimen rather than grasp, improving the surgical field's visibility and access. Clinical outcomes of patients who underwent RPRPD performed between August 2020 and September 2023 by a single surgeon across two centers in Taiwan and Japan were reviewed. RESULTS: Fifty patients underwent RPRPD using the single-site plus-two ports technique. The gooseneck traction technique enabled goodsurgical field deployment and allowed for unrestricted movement of robotic arms with no collisions with the assistant instruments. The median operative time was 351 min (250-488 min), including 271 min (219-422 min) of console time and three minutes (2-10 min) of docking time. The median estimated blood loss was 80 mL (1-872 mL). All RPRPD procedures were successfully performed without the need for conversion to open surgery. Postoperative major morbidity (i.e., Clavien-Dindo grade ≥ IIIa) was observed in 6 (12%) patients and median postoperative hospital stay was 13 days. CONCLUSIONS: The single-site plus-two ports RPRPD with the gooseneck traction proves to be a safe, feasible option, facilitating surgical field visibility and robotic arm maneuverability.
ABSTRACT
OBJECTIVE: To evaluate the different perioperative variables that may serve as important clinical predictors when selecting patients for outpatient single-port robot-assisted radical prostatectomy (SP-RARP). PATIENTS AND METHODS: A retrospective review was performed on the Institutional Review Board-approved, prospectively maintained database to identify 485 consecutive patients who underwent SP-RARP between 2018 and 2023. A comparison analysis was performed on patients who were managed as outpatients vs inpatients following their respective SP-RARP. A separate analysis was performed after excluding patients with pre-planned admissions to identify the risk factors for unplanned admissions. RESULTS: All procedures were successfully completed without any conversion or additional ports. After excluding patients with pre-planned admissions, outpatient SP-RARP was successfully achieved in 86.6% with a median (interquartile range) length of stay of 4.6 (3.8-6.1) hours. Our multivariate regression analysis identified cardiac comorbidity and preoperative International Prostate Symptom Score (IPSS) as predictors of outpatient SP-RARP. In addition, the absence of cardiac comorbidity, previous abdominal surgery, and lower postoperative pain score were protective against the risk of unplanned admission. Furthermore, both inpatient and outpatient encounters had comparable 90-day rates of postoperative complication (P = 0.136) and hospital re-admission (P = 0.942). CONCLUSION: Outpatient management models could be successfully achieved in most patients who underwent SP-RARP (86.6%) while maintaining similarly low perioperative morbidity profile. Nevertheless, appropriate patient selection based on the baseline clinicodemographic characteristics remains essential to ensure the safety and ongoing success of outpatient SP-RARP.
ABSTRACT
The objective was to explore the efficacy of single-port laparoscopic percutaneous extraperitoneal closure using double-modified hernia needles with hydrodissection (SLPEC group) and two-port laparoscopic percutaneous extraperitoneal closure (TLPEC group) for the treatment of giant indirect inguinal hernias in children. We performed a retrospective review of all children with giant indirect inguinal hernias (inner ring orifice diameter ≥ 1.5 cm) who underwent laparoscopic high ligation of the hernia sac at FuJian Children's Hospital from January 2019 to December 2021. We collected data from the medical records of all the children and analysed their clinical characteristics and operation-related and follow-up information. Overall, this study included a cohort of 219 patients with isolated giant inguinal hernias who had complete clinical data and who had undergone laparoscopic high ligation of the hernia sac at our centre. All procedures were successfully performed for the 106 patients who underwent SLPEC and for the 113 patients who underwent TLPEC at our centre. There were no statistically significant differences in patient age, sex, body weight, follow-up time or the side of inguinal hernia between the SLPEC group and the TLPEC group (P = 0.123, 0.613, 0.121, 0.076 and 0.081, respectively). However, there were significant differences in the bleeding volume, visual analogue scale (VAS) score, and postoperative activity time between the two groups (P ≤ 0.001). The operation times in the TLPEC group were significantly longer than those in the SLPEC group (P = 0.048), but there were no significant differences in hospital length of stay or hospitalization costs between the two groups (P = 0.244 and 0.073, respectively). Incision scars were found in 2 patients in the SLPEC group and 9 patients in the TLPEC group, and there was a significant difference between the two groups (P = 0.04). However, the incidence of ipsilateral hernia recurrence, surgical site infection, suture-knot reactions and chronic inguinodynia did not significantly differ between the two groups (P = 0.332, 0.301, 0.332 and 0.599, respectively). Postoperative hydrocele occurred in only 1 male child in the SLPEC group and in no male children in the TLPEC group, and there was no difference between the two groups (P = 0.310). In this study, there were no cases of testicular atrophy or iatrogenic ascent of the testis. Compared with the TLPEC group, the SLPEC group had the advantages of a concealed incision, light scarring, minimal invasiveness, a reduced operation time, minimal bleeding, mild pain and rapid recovery. In conclusion, SLPEC using double-modified hernia needles with hydrodissection and high ligation of the hernia sac is a safe, effective and minimally invasive surgery. The cosmetic results are impressive, and the follow-up results are promising.

PURPOSE: Single-Port Robot-Assisted Partial Nephrectomy (SP-RAPN) can be performed by transperitoneal and retroperitoneal approaches. However, there is a lack of surgical outcomes for novel Retroperitoneal Low Anterior Access (LAA) in SP-RAPN. The study compared outcomes of the standard approach (SA), considering transperitoneal (TP) and posterior retroperitoneal (RP) access vs LAA in SP-RAPN series. METHODS: 102 consecutive patients underwent SP-RAPN between 2019 and 2023 at a tertiary referral robotic center were identified. Baseline characteristics, peri- and post-operative outcomes were collected. Patients were stratified according to surgical approach into standard (RP or TP) vs LAA and, subsequently, RP vs LAA. Multivariable logistic regression analysis was used to test the probability of the same-day discharge adjusting for comorbidity indexes. RESULTS: Overall, 102 consecutive patients were included in this study (68 SA - 26 TP and 42 posterior RP vs 34 LAA). Median age was 60 (IQR 51.5-66) years and median BMI was 31 (IQR 26.3-37.6). No baseline differences were observed. LAA exhibited significantly shorter length of stay (LOS) (median 10 [IQR 8-12] vs 24 [IQR 12-30.2.] hours, p < .0001), reduced post-operative pain (p < .0001) and decreased narcotic use on 0-1 PO Day (p < .001) compared to SA and RP only. Multivariate analysis, adjusting for comorbidities, identified LAA as a strong predictor for Same-Day Discharge. CONCLUSION: LAA is an effective approach as well as RP and TP, regardless of the renal mass location, whether it is anterior or posterior, upper/mid or lower pole, yielding favorable outcomes in LOS, post-operative pain and decreased narcotics use compared to SA in SP-RAPN.

OBJECTIVE: To demonstrate the anatomical and technical highlights of nerve-sparing deep endometriosis (DE) surgery with rectal discoid resection using a newer single-port robotic system. DESIGN: Step-by-step demonstration of this method was provided with narrated video footage. SETTING: The surgery was performed at an urban general hospital. Single-port laparoscopic surgery is a useful surgical approach in gynecology because of the excellent cosmetic results but shows challenges including reduced intracorporeal triangulation and conflict with nonarticulating instruments. The range of indications is thus limited. PATIENT: A 46-year-old woman was referred with severe pelvic pain, dysmenorrhea, and pain on defecation. Magnetic resonance imaging revealed uterine adenomyosis, bilateral ovarian endometriomas, and 3 cm of rectal endometriosis. Computed tomography colonography confirmed 38% stenosis of the rectum. INTERVENTION: A newer single-port robotic system was used. MAIN OUTCOME MEASURES: The main outcome measures were technical safety and feasibility of intrapelvic complex DE surgery using a newer single-port robotic platform. RESULTS: The procedure was performed using nine steps with a da Vinci SP surgical system (Intuitive Surgical, Sunnyvale, California). Importantly, the surgical steps were completely identical to conventional multiport laparoscopic or robotic surgery. This suggests that conventional laparoscopic or robotic skills are highly transferrable to the newer system. The surgical steps are as follows: The newer single-port system offered several advantages, including high-resolution three-dimensional visualization, articulating instruments (intracorporeal instrument triangulation), and improved dexterity and range of motion. These advantages allow precise dissection even in difficult situations such as DE. CONCLUSIONS: This appears to be the first reported use of the da Vinci SP for nerve-sparing DE surgery or rectal discoid resection. The newer single-port robotic system can provide the same quality of surgery as conventional multiport laparoscopic and robotic platforms with cosmetic advantages for the treatment of complex pelvic pathologies.
ABSTRACT
INTRODUCTION: Total cyst excision and Roux-en-Y hepaticojejunostomy is the standard procedure for treating congenital choledochal cysts, which requires high surgical skills. Our aim is to introduce the experience with the SHURUI single-port robotic system in pediatric surgery. PRESENTATION OF CASE: In this study, we present a case demonstrating the application of the SHURUI single-port robotic system in performing choledochal cyst excision and Roux-en-Y hepaticojejunostomy in a pediatric patients. Roux-en-Y anastomosis was constructed extracorporeally, then choledochal cyst excision and hepaticojejunostomy was performed intracorporally using the SHURUI Surgical System. Surgical complications and the wound outcomes were assessed. The total duration of the operation was 292 min, comprising an extracorporeal time of 45 min, docking time of 19 min, and intracorporal time of 183 min. The estimated blood loss was minimal at only 2 mL. The patient was discharged 6 days post-operation, and exhibited satisfactory recovery at the one-month follow-up. DISCUSSION: This case represents an initial experience with the SHURUI Surgical System in managing a pediatric choledochal cyst. The results indicate that the system is feasible and safe for this procedure, and may have some advantages over laparoscopic and open approaches. CONCLUSION: The SHURUI Surgical System is both feasible and safe in pediatric surgery, and it may offer certain advantages over laparoscopic and open approaches.
ABSTRACT
Background: Single-incision laparoscopic cholecystectomy (SILC) is a minimally invasive procedure designed to minimize the number and size of the incisions needed for cholecystectomy. Titanium clips are traditionally used to close the cystic duct and artery. Although it is considered safe, dislodgement can result in bleeding and biliary leakage. Using LigaSure for duct sealing is still controversial. The aim of this study was to evaluate the safety and feasibility of using LigaSure to close the cystic duct during SILC. Methods: A prospective study over two years was conducted at the General Surgery Department, Mansoura University Hospital, on 102 patients, 51 in each group. They underwent SILC using LigaSure (Group 1) or titanium clips (Group 2) to control the cystic duct and artery. Results: The data analyzed included demographic data, operative time, intra- and postoperative complications, postoperative pain, and hospital stay. The operative time was significantly shorter in LigaSure group (68.5 ± 9.8 versus 72.9 ± 10.6 minutes in the clips group, P .03). There was no significant difference between the two groups regarding postoperative bile leak or bleeding. However, two cases in Group 1 and four cases in Group 2 were converted to multiple port laparoscopic cholecystectomy; this was statistically nonsignificant. Postoperative pain and hospital stay showed no significant difference between the two groups. Two patients in each group developed port-site incisional hernia. Conclusions: Clipless SILC using LigaSure is a feasible and safe procedure with acceptable morbidity with shorter operative time than SILC using clips. Nevertheless, the risk of port-site incisional hernia should be explained to the patients.
ABSTRACT
BACKGROUND: Benign breast lumps affect 10% of women in their lifetimes. Endoscopic surgery could be an alternative surgical technique for benign breast tumors because it is performed through small wounds hidden in inconspicuous areas. The aim of this study was to explore the safety and esthetic effects of endoscopic surgery in the treatment of benign breast disease. METHODS: This retrospective cohort study analyzed 363 patients with benign breast tumors from August 2021 to December 2023 in the Sixth Affiliated Hospital of Sun Yat-Sen University, of whom 118 underwent transaxillary single-port endoscopic surgery and 245 underwent traditional open surgery. Clinicopathologic characteristics, surgery type, hospital stay, and complications were analyzed to assess the effectiveness of the procedure for benign breast tumors. RESULTS: Breast tumor resection was successfully performed in 363 patients by endoscopic surgery or traditional open surgery. Endoscopic procedures demonstrated longer durations of surgery (98.54 ± 35.17 min vs. 70.28 ± 26.06 min, p < 0.01) and postoperative drainage (64.30 ± 34.92 mL vs.18.49 ± 19.86 mL, p < 0.01), but there was less blood loss. The nipple-areolar complex of the patients who underwent endoscopic resection was significantly more sensitive than the traditional open surgery group. Patients in the endoscopic group reported higher satisfaction with surgical outcome (13.10 ± 1.97 vs. 12.63 ± 1.90, p < 0.01). And there was a significant difference in the wound scar and cosmetic outcome total score between the two groups. CONCLUSION: Transaxillary single-port endoscopic surgery is effective and safe and improves postoperative nipple-areolar sensation and cosmetic outcome, as compared to the conventional technique.
ABSTRACT
BACKGROUND: Most adult cases of intussusception are caused by colorectal cancer, and emergency surgery is performed when symptoms such as abdominal pain and vomiting are present. The patient must customarily undergo both bowel decompression and radical surgery for colorectal cancer at the same time, and laparotomy is generally the procedure of choice. CASE PRESENTATION: An 86-year-old woman presented to our hospital with diarrhea and bloody stools. Preoperative examination revealed the presence of a cancerous tumor in the advanced part of the transverse colon and bowel intussusception. Radical surgery was successfully performed using the laparoscopic single-port technique through a small incision at the umbilical site to treat intussusception caused by cecum cancer. CONCLUSIONS: With only one wound site at the umbilicus, this single-port laparoscopic approach is much less invasive than endoscopic surgery that requires four to five incision wounds to perform the procedure. Furthermore, the patient was discharged without major complications and this surgical technique could be of great benefit if established as a standard procedure in the future.
ABSTRACT
BACKGROUND: Robotic surgery has emerged as a promising approach for managing complex hepatic malignancies. This report presents a case of a single-port robotic liver resection for a patient with recurrent hepatocellular carcinoma (HCC) and metastases, focusing on the surgical technique and outcomes. METHOD: An 18-year-old female with a history of left hepatectomy for fibrolamellar HCC underwent robotic liver resection using the Da Vinci SP Surgical System. The procedure entailed excising a 30 mm tumor in liver segment 4 (Sg4) along with peritoneal metastases in the superior pole of the spleen and cardiophrenic lymph node metastasis. Surgical techniques comprised adhesiolysis, resection of the peritoneal nodule, Sg4 partial liver resection, and excision of the cardiophrenic lymph node. RESULTS: The operative time was 310 min, with a blood loss of 37 mL. The patient experienced an uneventful postoperative course and was discharged home after 8 days. Partial liver resection of Sg4 revealed a moderately differentiated HCC with negative resection margins. Additionally, excision of peritoneal metastases in the superior pole of the spleen and cardiophrenic lymph nodes, consistent with metastasis, was performed. Notably, the Da Vinci SP system's relocation function proved useful in this case, particularly in slender patients with multiple distant metastases. CONCLUSION: This case underscores the importance of technological advancements in robotic surgery. The Da Vinci SP system, with its advantageous features, shows promise in challenging clinical scenarios. Its ability to facilitate precise navigation and manipulation within the patient's restricted abdominal cavity contributed to the observed successful outcome.
ABSTRACT
Twenty years have passed since uniportal video-assisted thoracoscopic surgery (VATS) was first reported. Several reports have already proven the minimal invasiveness of uniportal VATS. In addition, two large clinical trials recently demonstrated the benefits of segmentectomy for small peripheral early-stage non-small cell lung cancer. Uniportal VATS segmentectomy is considered the most beneficial minimally invasive surgery for patients with early-stage lung cancer. However, a high level of skill and experience are required to achieve this goal. Only a few reports have discussed specific techniques, particularly for complex segmentectomies. In this Special Issue, we reviewed previous reports on uniportal VATS segmentectomy regarding the indications, instrument selection, marking of the tumor location, methods of intersegmental plane identification, and lymph node dissection, including our own techniques with video content.
ABSTRACT
Background: With the introduction of the da Vinci single-port (SP) robot platform, surgery in a narrow space has become easier, and using this, extraperitoneal radical prostatectomy has been frequently performed recently. However, studies comparing it with existing methods are still lacking. Therefore, in this study, we compared the initial extraperitoneal single-port robot-assisted radical prostatectomy (spRARP) with intraperitoneal multiport robot-assisted radical prostatectomy (mpRARP) and tried to investigate the feasibility of extraperitoneal spRARP. Methods: We retrospectively analyzed patients who underwent RARP performed between January 2019 and April 2023. A total of 184 consecutive patients were enrolled in this study: 64 underwent spRARP and 120 underwent mpRARP. Patient characteristics before and after surgery were investigated, and period of passing gas, foley maintenance period, length of hospital stay, and pain changes were compared and analyzed to estimate post-surgery recovery. To address inherent biases stemming from differing patient characteristics at baseline, we performed an additional analysis after propensity score matching (PSM) (ratio, 1:1). Results: After PSM, both the spRARP and mpRARP groups consisted of 64 patients each. On preoperative examination, there were no significant differences in prostate-specific antigen level, Gleason score (GS), prostate volume, magnetic resonance imaging T stage, or Prostate Imaging-Reporting and Data System score between the two groups. Following surgery, there were no significant differences in operative and console time between the two groups. Notably, the estimated blood loss was considerably lesser in the spRARP group than in the mpRARP group (P=0.049). When comparing pathologic outcomes, the GS, T stage, positive surgical margin, extracapsular extension, and seminal vesicle invasion rates showed no significant differences between the two groups. Four patients who underwent spRARP and six who underwent mpRARP suffered Clavien-Dindo classification grade 3 and 4 complications. After 3 months, there were no significant differences in incontinence or potency between the two groups. However, even after PSM, the period of passing gas was earlier in the spRARP group than in the mpRARP group. Conclusions: In this study, both the extraperitoneal spRARP and transperitoneal mpRARP groups exhibited similar complication rates and surgical outcomes. Furthermore, the spRARP group had a short surgical time and demonstrated early recovery. Therefore, extraperitoneal spRARP is a feasible procedure that is expected to become increasingly popular in the future.
