Is single incision laparoscopic surgery (SILS) for gastric gastrointestinal stromal tumor (GIST) dependent on the location of the tumor?

BackgroundWe compared the surgical outcomes of single-incision laparoscopic surgery (SILS) and conventional laparoscopic surgery (CLS) for gastric gastrointestinal stromal tumor (GIST).MethodsWe performed single-incision gastric wedge resection on prospectively-enrolled 15 consecutive patients with gastric GIST between November 2020 and April 2022 in a single tertiary center. The early perioperative outcomes of these patients were compared to those of patients who underwent CLS. The indications did not differ from those for conventional laparoscopic procedures for gastric GIST.ResultsIn total, 30 patients were assigned to the SILS (n = 15) and CLS (n = 15) groups. There were no significant differences in the estimated blood loss and intraoperative blood transfusion between the SILS and CLS groups. There were no intraoperative complications or conversions to multiple-port or open surgery in the SILS group. Proximally located tumors were more commonly treated with CLS than with SILS (P = 0.045). GISTs located in the greater curvature were more commonly treated with SILS than with CLS, although the difference was not statistically significant (P = 0.08). The mean incision length in the SILS group was 4.1 cm shorter than that in the CLS group (3.2 ± 0.7 and 7.3 ± 5.2 cm, respectively, P = 0.01). The postoperative analgesic dose was significantly lower in the SILS than in the CLS group (0.4 ± 1.4 and 2.1 ± 2.3, respectively P = 0.01). Also, the duration of postoperative use of analgesic was shorter in SILS than in CLS (0.4 ± 0.7 and 2.0 ± 1.8, respectively, P = 0.01). There were no significant differences in the early postoperative complications between the groups.ConclusionsSILS is as safe, feasible, and effective for the treatment of gastric GIST as CLS with comparable postoperative complications, pain, and cosmesis. Moreover, SILS can be considered without being affected by the type or location of the tumor.

Application of single-port procedure and ERAS management in the laparoscopic myomectomy

ObjectiveAdvances in surgical techniques and perioperative management are the two major contributing factors to improved surgical outcomes. The purpose of the current study was to compare the efficacy of single-port surgery and perioperative enhanced recovery after surgery (ERAS) management in laparoscopic myomectomy.MethodsThe present study included 120 patients undergoing laparoscopic myomectomy in the Gynecological Ward of Quzhou Affiliated Hospital of Wenzhou Medical University. According to the traditional perioperative management mode and ERAS management, multi-port and single-port procedures, all patients were assigned to the Conventional-SPLS (Single-Port Laparoscopic Surgery with conventional perioperative care) group (n = 34), Conventional-Multi (multi-port laparoscopic surgery with conventional perioperative care) group (n = 47), and ERAS (multi-port laparoscopic surgery with ERAS perioperative care) group (n = 39). The surgical outcomes of the three groups were compared operation time, intraoperative blood loss, variations in postoperative hemoglobin, postoperative walking time, postoperative flatus expelling time, postoperative hospital stay, and visual analog scale (VAS) scores at 6 and 12 h following surgery.ResultsThe ERAS group recovered the quickest in terms of postoperative walking time and flatus expelling duration. The ERAS group also recovered the shortest postoperative hospital stay (3.85 ± 1.14 days), which differed significantly from that in the Conventional-Multi group, but not significantly from that in the Conventional-SPLS group. In terms of VAS scores at 6 and 12 h after surgery, the ERAS group had the lowest pain intensity, which differed significantly from that of the other two groups. The effect of surgical procedures or postoperative care on hospital stay was assessed using multiple regression analysis. The results demonstrated that ERAS was an important independent contributor to reducing postoperative hospital stay (β = 0.270, p = 0.002), while single-port surgery did not affect this index (β = 0.107, p = 0.278).ConclusionIn laparoscopic myomectomy, perioperative ERAS management could control postoperative pain and shorten hospital stay. Single-port surgery could speed up the recovery of gastrointestinal function and postoperative walking time, but it did not affect postoperative pain management or the length of hospital stay. Thus, the most effective approach to improving postoperative outcomes in laparoscopic myomectomy was the application of perioperative ERAS management.

Comparison between single incision laparoscopic cholecystectomy using conventional laparoscopic instruments vs. four port laparoscopic cholecystectomy in patients of symptomatic cholelithiasis: a prospective randomised study

Background: The desire to reduce invasiveness, pain, discomfort and improve cosmesis and early return of patient to normal activities is the basis for single incision laparoscopic surgery. The primary aim was to compare post-operative pain and the secondary aim to compare duration of surgery, intraoperative bile spill or stone spill, duration of hospital stay, any postoperative complications and cosmetic outcome between SILC and the gold standard for symptomatic gall stone disease, FPLC (Four port laparoscopic cholecystectomy). Methods: A total of 150 patients were randomized into two groups, A (SILC) and B (FPLC). Post-operative pain and other intra-operative and post -operative parameters were compared. Results: The age ranged between 20 years to 76 years most of them being females with body mass index ranging between 19 and 35 kg/m2. Comparison of pain score was done using MEWS scale; which was found to be statistically significantly SILC at 6 hours, mean difference (MD)-0.833 while at 24 hours the difference was not significant (MD- 0.234). Duration of surgery was significantly more (MD-12.17 minutes) in SILC. No addition of port or conversion to open cholecystectomy was required. There were no significant difference between post-operative complications between the two groups. Cosmesis was significantly better in terms of look of the scar (MD-0.867) and recommending it to their relatives (MD-0.700) in SILC group. Conclusions: SILC is a safe and easily learnable procedure which can be safely be done using conventional laparoscopic instruments in low risk patients. Duration of surgery even after expertise is gained remains to be more than FPLC.

Effects of sarcopenia and myosteatosis are alleviated in reduced port surgery for diverticulitis

PurposeMany studies report the predictive value of sarcopenia, myosteatosis, and visceral fat for clinical outcome after surgery. Radiological analysis of body composition is a valuable tool for identifying high-risk patients undergoing major abdominal surgery. Despite the high prevalence of diverticular disease, patients with benign conditions have hardly been studied in this context. This study aims to evaluate the impact of reduced port surgery on the outcome of patients with diverticulitis, adjusting for body composition.MethodsWe assessed body composition profiles using preoperative CT slices at the level of the third lumbar vertebra in consecutive patients undergoing single-port elective surgery for diverticulitis in a single center. The effects of sarcopenia, myosteatosis, and visceral fat on mortality and complications were analyzed and adjusted for age and gender.ResultsWe enrolled 99 patients with diverticulitis undergoing elective single port surgery in this study. Of the patients, 71.2% had sarcopenia and 60.6% had myosteatosis. The overall complication rate was 17.2%, and the rate of anastomotic leakage was 4.0%. Thirty-day mortality was 2.0%. Loss of skeletal muscle mass, myosteatosis, and visceral fat were not associated with higher complication or mortality rates in our cohort.ConclusionBody composition profiles had no impact on the clinical course in our cohort. Minimally invasive surgery may potentially compensate for the adverse effects of sarcopenia and myosteatosis in diverticulitis.

Feasibility and Surgical Outcomes of Hybrid Robotic Single-Site Hysterectomy Compared with Single-Port Access Total Laparoscopic Hysterectomy.

We compared surgical outcomes between single-port access total laparoscopic hysterectomy (SPA-TLH) and hybrid robotic single-site hysterectomy (RSSH), a new technique of combining the benefits of SPA-TLH with RSSH in this study. A total of 64 patients were retrospectively analyzed. They underwent either hybrid RSSH or SPA-TLH for benign gynecologic disease between December 2018 and August 2021. To assess the feasibility of hybrid RSSH, the clinical characteristics and surgical outcomes were compared between the hybrid RSSH group (n = 29) and the SPA-TLH group (n = 35). All of the surgeries were completed without requiring additional ports or conversion to laparotomy. The surgical outcomes including total operative time, uterine weight, estimated blood loss, hemoglobin changes, length of hospital stay, and postoperative pain scores were not significantly different between the two groups. The colpotomy time, including the detachment of the uterosacral and cardinal ligaments, was shorter in the hybrid RSSH group than in the SPA-TLH group (8.0 min vs. 14.0 min; p = 0.029). However, the vaginal cuff closure time was longer in the hybrid RSSH group than in the SPA-TLH group (15.0 min vs.10.0 min; p = 0.001). No difference was observed with regards to intraoperative and postoperative complications. Hybrid RSSH appears to be a feasible procedure for hysterectomy in patients with benign gynecologic diseases.

SINGLE-INCISION LAPAROSCOPY VERSUS STANDARD LAPAROSCOPY FOR COLORECTAL SURGERY : A SYSTEMATIC REVIEW

Background: Colorectal cancer (CRC) is the third most prevalent malignancy worldwide. Only surgical resection is curative for colorectal cancer. Recent advances in surgical techniques, such as robot-assisted laparoscopic surgery (RALS), single-incision laparoscopic surgery (SILS), and natural orifice transluminal endoscopic surgery (NOTES), etc., have benefited colorectal cancer patients tremendously. The aim: This study aims to compare single-incision laparoscopy and conventional laparoscopy for colorectal surgery. Methods: By comparing itself to the standards set by the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020, this study was able to show that it met all of the requirements. So, the experts were able to make sure that the study was as up-to-date as it was possible to be. For this search approach, publications that came out between 2013 and 2023 were taken into account. Several different online reference sources, like Pubmed and SagePub, were used to do this. It was decided not to take into account review pieces, works that had already been published, or works that were only half done. Result: In the PubMed database, the results of our search brought up 201 articles, whereas the results of our search on SagePub brought up 119 articles. The results of the search conducted for the last year of 2013 yielded a total 54 articles for PubMed and 23 articles for SagePub. In the end, we compiled a total of 16 papers, 11 of which came from PubMed and 5 of which came from SagePub. We included six research that met the criteria. Conclusion: Previous studies have consistently shown that complications within 30 days postoperatively and incision size in patients with single port are better than patients with multiport. Perioperative outcome and long-term survival rates were similar between the two groups.

Safety Issues in the Development of an Innovative Medical Parallel Robot Used in Renal Single-Incision Laparoscopic Surgery.

Robotic-assisted single-incision laparoscopic surgery (SILS) is becoming an increasingly widespread field worldwide due to the benefits it brings to both the patient and the surgeon. The goal of this study is to develop a secure robotic solution for SILS, focusing specifically on urology, by identifying and addressing various safety concerns from an early design stage. Starting with the medical tasks and protocols, the technical specifications of the robotic system as well as potential; hazards have been identified. By employing competitive engineering design methods such as Analytic Hierarchy Process (AHP), Risk assessment, and Failure Mode and Effects Analysis (FMEA), a safe design solution is proposed. A set of experiments is conducted to validate the proposed concept, and the results strongly support the development of the experimental model. The Finite Element Analysis (FEA) method is applied to validate the mechanical architecture within a set of simulations, demonstrating the compliance of the robotic system with the proposed technical specifications and its capability to safely perform SILS procedures.

A simple gasless single-port laparoscopy suitable for use in middle- and low-income countries or primary hospitals.

The purpose of the present study is to explore the effectiveness of a modified suspension method combined with gasless single-port laparoscopy (MS-GSPL) for the treatment of benign ovarian tumors. The aim of this approach is to provide a convenient, economical, and minimally invasive method that is suitable for widespread use, even in middle- and low-income countries or primary hospitals. Retrospective analysis of patients who underwent laparoscopic unilateral ovarian cystectomy due to benign ovarian tumors from January 2019 to December 2019.Thirty-six cases were treated with MS-GSPL, and 36 cases were treated with single-port laparoscopy (SPL). The patients' medical records, perioperative surgical outcomes, postoperative pain scores and complications were reviewed and compared. There are no significant differences in age, body mass index, previous pelvic surgery, tumor diameter, and tumor pathologic outcomes between MS-GSPL group and SPL group. The median operation times were 50 (Q1~Q3, 44~62.25) min in the MS-GSPL group and 60.5 (Q1~Q3, 57.25~78) min in the SPL group with a significant difference. The median estimated blood loss was 40 (Q1~Q3, 30~50) mL in the MS-GSPL group and 50(Q1~Q3, 30~60) mL in the SPL group with no significant difference. Compared with SPL group, patients in MS-GSPL group had earlier postoperative exhaust times, shorter hospital stays and lower costs, and all these differences were statistically significant (p < 0.05). There was a strong positive correlation between operation time and BMI in the MS-GSPL groups. The patients receiving MS-GSPL treatment have quick postoperative recoveries. MS-GSPL is a novel, safe and economical surgical method that is suitable for extensive clinical development in middle- and low-income countries or primary hospitals.

Stoma-site approach single-port laparoscopic versus conventional multi-port laparoscopic Miles procedure for low rectal cancer: A prospective, randomized controlled trial

The aim of this study was to compare perioperative outcomes of patients with low rectal cancer after stoma-site approach single-port laparoscopic Miles procedure or conventional multi-port laparoscopic Miles procedure, as well as to evaluate the safety and efficacy of stoma-site approach single-port laparoscopic surgery in low rectal cancer. Between September 2020 and September 2021, 51 low rectal cancer patients scheduled for Miles procedure at the Department of Gastrointestinal Surgery of Affiliated Hospital of North Sichuan Medical College were randomly assigned to the single-port laparoscopic surgery group (SPLS) and the multi-port laparoscopic surgery (MPLS) group. The perioperative outcomes were compared between the two groups. In this study, 25 patients underwent SPLS and 26 underwent MPLS. All patients completed the study, and there were no perioperative deaths in either group. Observation indicators such as intraoperative bleeding (39mL vs. 41mL), number of lymph nodes (20.12±3.29 vs. 21.84±3.74), average hospital stay (7.15±1.52 vs. 7.64±1.66), and time to flatulence (2.5d vs. 2.5d) showed no significant differences between the SPLS and MPLS groups (p>0.05). However, the operation duration (180min vs. 118 min) and perioperative complications showed statistically significant differences between the two groups (p<0.05). In addition, patients in the SPLS group had significantly higher satisfaction scores than those in the MPLS group (p<0.05). For patients with low rectal cancer requiring Miles surgery, stoma-site approach single-port laparoscopic surgery has comparable safety and efficacy to multi-port laparoscopic surgery.

Efficacy of a continuous wound infiltration system for postoperative pain management in gynecologic patients who underwent single-port access laparoscopy for adnexal disease.

Single-port access (SPA) laparoscopy requires only one incision, unlike conventional laparoscopy. However, its umbilical incision is larger than that of conventional laparoscopy and can be vulnerable to postoperative pain. This study aimed to evaluate whether simultaneous use of a continuous wound infiltration (CWI) system and intravenous patient-controlled analgesia (IV PCA) effectively decreases surgical site pain in patients who underwent SPA laparoscopy due to gynecologic adnexal disease. A total of 371 patients who underwent SPA laparoscopy and who received IV PCA or CWI was retrospectively reviewed (combined group [CWI + IV PCA, n = 159] vs. PCA group [IV PCA only, n = 212]). To evaluate postoperative pain management, the numeric rating scale (NRS) pain score after surgery, total amount of fentanyl administered via IV PCA, and additional pain killer consumption were collected. The NRS scores at 12 h (1.90 ± 1.11 vs. 2.70 ± 1.08, p < 0.001) and 24 h (1.82 ± 0.82 vs. 2.11 ± 1.44, p = 0.026) after surgery were significantly lower in the combined group than in the PCA group. The total amount of PCA fentanyl was significantly smaller in the combined group than in the PCA group (p < 0.001). The total quantity of rescue analgesics was smaller in the combined group than in the PCA group (p < 0.05). Combined use of the CWI system and IV PCA is an effective postoperative pain management strategy in patient who underwent SPA laparoscopy for adnexal disease.

Laparoendoscopic single-site surgery for deep infiltrating endometriosis based on retroperitoneal pelvic spaces anatomy: a retrospective study

Transumbilical single-port laparoscopy is widely used in gynecological surgery. However, it is rarely used in the treatment of deep infiltrating endometriosis due to its own shortcomings and the complex condition of deep infiltrating endometriosis. The study aims to introduce a transumbilical single-port laparoscopic surgery based on retroperitoneal pelvic spaces anatomy, which can complete the operation of deep infiltrating endometriosis more easily. A retrospective analysis of 63 patients with deep infiltrating endometriosis treated by transumbilical single-port laparoscopy using this method was conducted. The operation duration was 120.00 (85.00 ± 170.00) (35–405) min, the estimated blood loss was 68.41 ± 39.35 ml, the postoperative hospital stay was 5.00 (4.00–6.00) days, and the incidence of postoperative complications was 4.76% (3/63). 1 patient was found to have intestinal injury during operation, 1 patient had ureteral injury after operation, and 1 patient had postoperative pelvic infection, with a recurrence rate of 9.52%. The postoperative scar score was 3.00 (3.00–4.00) and the postoperative satisfaction score was 9.00 (8.00–10.00). In summary, this study demonstrates the feasibility of transumbilical single-port laparoscopic surgery for deep infiltrating endometriosis based on retroperitoneal pelvic spaces anatomy. Hysterectomy, adenomyosis resection, etc. are also feasible with this method, boasting more obvious advantages. This method can make transumbilical single-port laparoscopy more widely used in deep infiltrating endometriosis.

Partial duodenectomy with seromyotomy by the "lift-and-cut" method for superficial nonampullary duodenal epithelial tumors: A novel technique.

The therapeutic strategy for superficial nonampullary duodenal epithelial tumors remains controversial. We developed a novel surgical technique for superficial nonampullary duodenal epithelial tumors. We report the initial two cases managed with this method. We endoscopically confirmed the tumor location and circumferentially incised the seromuscular layer of the duodenum along it. After circumferential seromyotomy, the submucosal layer was expanded by endoscopic insufflation, and the target lesion was sufficiently lifted. The submucosal layer, including the target lesion, was stapled and resected after confirming the absence of problems with endoscopic passage. The seromuscular layer was continuously sutured to bury and reinforce the stapler line. Single-incision laparoscopic surgery was performed in one case. The resected specimens measured 52 × 32 mm and 50 × 26 mm with negative surgical margins. Both patients were discharged without complications and demonstrated no evidence of stenosis. Compared with previously reported procedures, this method of partial duodenectomy with seromyotomy for superficial nonampullary duodenal epithelial tumors is promising, simple, and safe.

Artificial Intelligence-Based Hazard Detection in Robotic-Assisted Single-Incision Oncologic Surgery.

Single-incision surgery is a complex procedure in which any additional information automatically collected from the operating field can be of significance. While the use of robotic devices has greatly improved surgical outcomes, there are still many unresolved issues. One of the major surgical complications, with higher occurrence in cancer patients, is intraoperative hemorrhages, which if detected early, can be more efficiently controlled. This paper proposes a hazard detection system which incorporates the advantages of both Artificial Intelligence (AI) and Augmented Reality (AR) agents, capable of identifying, in real-time, intraoperative bleedings, which are subsequently displayed on a Hololens 2 device. The authors explored the different techniques for real-time processing and determined, based on a critical analysis, that YOLOv5 is one of the most promising solutions. An innovative, real-time, bleeding detection system, developed using the YOLOv5 algorithm and the Hololens 2 device, was evaluated on different surgical procedures and tested in multiple configurations to obtain the optimal prediction time and accuracy. The detection system was able to identify the bleeding occurrence in multiple surgical procedures with a high rate of accuracy. Once detected, the area of interest was marked with a bounding box and displayed on the Hololens 2 device. During the tests, the system was able to differentiate between bleeding occurrence and intraoperative irrigation; thus, reducing the risk of false-negative and false-positive results. The current level of AI and AR technologies enables the development of real-time hazard detection systems as efficient assistance tools for surgeons, especially in high-risk interventions.

The Ropivacaine Concentration Required for Ultrasound-Guided Rectus Sheath Block in Pediatric Patients Undergoing Single-Incision Laparoscopic Hernia Repair: A Sequential Allocation Dose-Finding Study.

The local anesthetic concentration required for ultrasound-guided rectus sheath block (RSB) in children remains unknown. Knowledge of appropriate ropivacaine concentration can help clinicians reduce local anesthetic toxicity risk when performing ultrasound-guided RSB in children. This study aimed to determine the appropriate ropivacaine concentration for ultrasound-guided RSB in children undergoing laparoscopic inguinal hernia repair. In this single-arm prospective study with an up-down sequential allocation design of binary response variables, 18 consecutive children aged 11 months to 7 years undergoing single-incision laparoscopic percutaneous extraperitoneal closure were assessed. Orotracheal intubation was performed without intravenous anesthesia or a neuromuscular relaxant. After intubation, ultrasound-guided RSB was performed with a ropivacaine dose of 0.30 ml/kg(0.15 ml/kgper side). Dixon's up-and-down method was used to determine the concentration, starting from 0.25% in 0.05% increments. Surgery commenced ≥15 min following RSB. Body movement or a 20% increase in heart rate or systolic blood pressure within 1 min of surgery initiation determined an unsuccessful RSB. The 95% effective concentration of ropivacaine needed for successful RSB was calculated using the probit test. The 95% effective concentration of ropivacaine needed for successful ultrasound-guided RSB was 0.31% (95% confidence interval, 0.25-7.29). The highest concentration of ropivacaine required for successful ultrasound-guided RSB in the group of patients in this study was 0.3%. The 95% effective concentration of ropivacaine (0.30 ml/kgtotal, 0.15 ml/kgper side) for ultrasound-guided RSB was 0.31% in children undergoing single-incision laparoscopic surgery under general anesthesia.

Integration of Virtual Reality in the Control System of an Innovative Medical Robot for Single-Incision Laparoscopic Surgery.

In recent years, there has been an expansion in the development of simulators that use virtual reality (VR) as a learning tool. In surgery where robots are used, VR serves as a revolutionary technology to help medical doctors train in using these robotic systems and accumulate knowledge without risk. This article presents a study in which VR is used to create a simulator designed for robotically assisted single-uniport surgery. The control of the surgical robotic system is achieved using voice commands for laparoscopic camera positioning and via a user interface developed using the Visual Studio program that connects a wristband equipped with sensors attached to the user's hand for the manipulation of the active instruments. The software consists of the user interface and the VR application via the TCP/IP communication protocol. To study the evolution of the performance of this virtual system, 15 people were involved in the experimental evaluation of the VR simulator built for the robotic surgical system, having to complete a medically relevant task. The experimental data validated the initial solution, which will be further developed.

Successful use of single-port laparoscopic surgery for ovarian cyst removal during pregnancy: a case series of three cases

Abstract Pregnant patients have an increased risk of torsion compared to that seen in nonpregnant patients, and those with larger cysts undergo torsion more frequently, which can cause obstructions during labor. The risks associated with emergent surgery are higher than those with elective surgery. Laparoscopic surgery can be safely performed during pregnancy. Single-port laparoscopic surgery is reported to be a minimally invasive laparoscopic technique. We report three cases of ovarian dermoid cysts, which were successfully removed during pregnancy through elective single-port laparoscopic surgery. In all cases, imaging showed a dermoid cyst and the cyst size was greater than 6 cm. All patients requested the surgery. The ovarian cysts were successfully removed by single-port laparoscopy without additional ports and without intra- or postoperative complications. All pregnancies progressed well and delivered vaginally at full term. The single-port laparoscopic approach is useful for removing ovarian cysts during pregnancy.

Comparative Study of Single Incision Laparoscopic Appendectomy (SILA) using Conventional Instruments versus Conventional Laparoscopic Appendectomy

Background: Laparoscopic surgery has become the procedure of choice for treating appendicitis. But in this evolving era, single incision laparoscopic surgery for appendicitis is gaining importance because of its cosmetic benefits. So, here we compared outcomes of two laparoscopic surgeries in terms of intraoperative time, postoperative pain, postoperative hospital stay, postoperative tolerance to diet, postoperative complications &amp; cosmesis. Method: A total of 100 patients who underwent laparoscopic appendectomy were studied. Patients were grouped under 2 categories randomly, group A undergoing single incision laparoscopic appendectomy (SILA) &amp; group B undergoing conventional three port laparoscopic appendectomy (CLA). Post operatively, duration of surgery, post-operative time, post-operative hospital stay, tolerance to diet, patients satisfaction were monitored. Result: Our study included 100 patients- 50 in group A(SILA) &amp; 50 in group B(CLA). Duration of surgery was significantly longer in group A as compared to group B(42.77 min vs 35.47 min ; p&lt;0.001). Patients had significantly lower pain score at 24 hours postoperatively in group A as compared to group B(3.38 vs 4.62, p&lt;0.001). Post-surgical complications in terms of superficial surgical site infection were more in group A(4 vs 2, p ). There was no significant difference in postoperative hospital stay and tolerance to oral feed postoperatively. There was no conversion to open appendectomy in both the groups. There was significant higher patients satisfaction score in group A patients (8.40 vs 6.12, p&lt;0.001). Conclusion: In addition to better cosmesis after SILA, SILA inflicts considerable less pain postoperatively than CLA with no significant differences in postoperative tolerance to oral diet, surgical site complications &amp; hospital stay.

Feasibility of single-port laparoscopic partial adrenalectomy with selective adrenal venous sampling and high-resolution ultrasound for unilateral aldosterone-producing adenomas

BackgroundThe surgical and endocrinological outcomes of single-port laparoscopic partial adrenalectomy for patients with aldosterone-producing adenomas are unknown. Precise diagnosis of intra-adrenal aldosterone activity and a precise surgical procedure may improve outcomes. In this study, we aimed to determine the surgical and endocrinological outcomes of single-port laparoscopic partial adrenalectomy with preoperative segmental selective adrenal venous sampling and intraoperative high-resolution laparoscopic ultrasound in patients with unilateral aldosterone-producing adenomas. We identified 53 patients with partial adrenalectomy and 29 patients with laparoscopic total adrenalectomy. Single-port surgery was performed for 37 and 19 patients, respectively. MethodsA single-center, retrospective cohort study. All patients with unilateral aldosterone-producing adenomas diagnosed by selective adrenal venous sampling and treated surgically between January 2012 and February 2015 were included. Follow-up with biochemical and clinical assessments was set at 1 year after surgery for short-term outcomes and was performed every 3 months after surgery. ResultsWe identified 53 patients with partial adrenalectomy and 29 patients with laparoscopic total adrenalectomy. Single-port surgery was performed for 37 and 19 patients, respectively. Single-port surgery was associated with shorter operative and laparoscopic times (odds ratio, 0.14; 95% confidence interval, 0.039–0.49; P = .002 and odds ratio, 0.13; 95% confidence interval, 0.032–0.57; P = .006, respectively). All single-port and multi-port partial adrenalectomy cases showed complete short-term (median 1 year) biochemical success, and 92.9% (26 of 28 patients) who underwent single-port partial adrenalectomy and 100% (13 of 13 patients) who underwent multi-port partial adrenalectomy showed complete long-term (median 5.5 years) biochemical success. No complications were observed with single-port adrenalectomy. ConclusionSingle-port partial adrenalectomy is feasible after selective adrenal venous sampling for unilateral aldosterone-producing adenomas, with shorter operative and laparoscopic times and a high rate of complete biochemical success.

Open, Laparoscopic, and Robotic Approaches to Treat Colorectal Cancer: A Comprehensive Review of Literature.

Surgery is usually required to treat colorectal cancer (CRC). Medical technology has advanced, providing various approaches to tackle this disease. Different surgeries are available, such as laparoscopic surgery, single-incision laparoscopic surgery, natural orifice transluminal endoscopic surgery, and robotic surgery. Laparoscopic surgery has several benefits including reduced blood loss and shorter recovery time. It can also improve lung function and minimize complications. However, it requires more time to perform and has a higher risk of complications during the procedure. Robotic surgery provides a three-dimensional view of the surgical area allowing for greater precision in rectal surgeries and access to difficult-to-reach pelvic regions. This method utilizes robotics technology which reduces surgical time and speeds up recovery for patients. There are various surgical options available for treating CRC; however, laparoscopic surgery and robotic surgery offer unique advantages despite their own drawbacks. As technology continues to evolve, medical techniques will continue improving existing methods while providing new options resulting in better outcomes for patients. Compared to laparoscopy, robotic surgery has a lower rate of operative conversions and a shorter learning curve. However, it also has some drawbacks, such as a longer docking time, lack of tactile sensation, and higher cost. Therefore, the choice of surgical method should depend on patient characteristics, surgeon preference and expertise, and available resources. Currently, specialized centers offer robotic surgeries which are more expensive and take longer compared to open and laparoscopic approaches. Nonetheless, they are considered safe and feasible when compared to traditional surgery. Short-term outcomes for robotic surgeries are better, while long-term postoperative complicationrates remain similar. However, there is a need for additional well-defined randomized control trials conducted across multiple centers to validate the use of robotic surgery over open and laparoscopic approaches. Improving patient care and outcomes is the objective of this comprehensive literature overview on surgical approaches for CRC.
