Project description:Single-port laparoscopic appendectomy (SPLA) was firstly introduced in 1998 and has been suggested potential advantages including better cosmetic outcome, less post-operative pain and avoidance of possible haemorrhagic complications from injuring epigastric vessels. However, single-port laparoscopic approach using conventional straight instruments may lead to internal and external conflicts and ergonomic discomfort, and new laparoscopic articulating instruments were developed to overcome these limitations of straight instruments. The ArtiSential® (LIVSMED Inc., Republic of Korea) is an 8-mm diameter pistol-handle instrument that has complete articulating function like human wrist and intuitive controllability. We present a technical report of SPLA for perforated appendicitis using ArtiSential® wristed articulated instrument. A 78-year-old female with a body mass index of 23.5 was referred to our emergency room with right lower quadrant abdominal pain. Abdominal computed tomography scan showed a distended tubular structure in the right lower quadrant (1.2 cm in diameter) with periappendiceal fluid collection. The patient's clinical presentation was highly indicative of perforated acute appendicitis. We performed SPLA with ArtiSential® grasper with the left hand, and this instrument helped us to allow greater manoeuvrability and dexterity with double triangulation technique. The total operation time was 40 min, and the patient was discharged without complications on the 1st day after surgery.
Project description:PurposeAs the number of gastric cancer survivors is increasing and their quality of life after surgery is being emphasized, single-port surgery is emerging as an alternative to conventional gastrectomy. A novel multi-degree-of-freedom (DOF) articulating device, the ArtiSential® device (LivsMed, Seongnam, Korea), was designed to allow more intuitive and meticulous control for surgeons facing ergonomic difficulties with conventional tools. In this study, we evaluated the feasibility of this new device during single-port laparoscopic distal gastrectomy (SP-LDG) for early gastric cancer (EGC) patients.Materials and methodsConsecutive patients diagnosed with EGC who underwent SP-LDG with ArtiSential® (LivsMed) graspers between April 2018 and August 2020 were enrolled in the study. The clinical outcomes were compared with those of a control group, in which prebent graspers (Olympus Medical Systems Corp) were used for the same procedures.ResultsSeventeen patients were enrolled in the ArtiSential® group. There was no significant difference in operative time (205.4±6.0 vs. 218.1±9.9 minutes, P= 0.270) or the quality of surgery, in terms of the number of retrieved lymph nodes (49.5±3.5 vs. 45.9±4.0, P=0.473), length of hospital stay (15.4±2.0 vs. 12.4±1.3 days, P=0.588), and postoperative complications (40.0% vs. 41.2%, P=0.595), between the ArtiSential® group and the control group.ConclusionsThe new multi-DOF articulating grasper is feasible and can be used as an alternative for prebent graspers during SP-LDG.
Project description:BackgroundMotorized articulating laparoscopic instruments (ALI) offer more degrees of freedom than conventional laparoscopic instruments (CLI). However, a difficult learning curve and complex instrument handling are still a problem of ALI. We compared the performance of new prototypes of motorized ALI with CLI in a series of standardized laparoscopic tasks performed by laparoscopic novices. Further, usability of the new ALI was assessed.MethodsA randomized cross-over study with 50 laparoscopic novices who either started with CLI and then changed to ALI (CA) or vice versa (AC) was conducted. All participants performed the European training in basic laparoscopic urological skills (E-BLUS) with each instrument in given order. Time and errors were measured for each exercise. Instrument usability was assessed.ResultsOverall, using CLI was significantly faster (CLI 4:27 min vs. ALI 4:50 min; p-value 0.005) and associated with fewer exercise failures in needle guidance (CLI 0 vs. ALI 12; p-value 0.0005) than ALI. Median amount of errors was similar for both instruments. Instrument sequence did not matter, as CA and AC showed comparable completion times. Regarding the learning effect, participants were significantly faster in the second attempt of exercises than in the first. In the needle guidance task, participants using CLI last demonstrated a significant speed improvement, whereas ALI were significantly slower in the second run. Regarding usability, CLI were preferred over ALI due to lighter weight and easier handling. Nevertheless, participants valued ALI's additional degrees of freedom.ConclusionUsing new motorized ALI in the E-BLUS examination by laparoscopic novices led to a worse performance compared to CLI. An explanation could be that participants felt overwhelmed by ALI and that ALI have an own distinct learning curve. As participants valued ALI's additional degrees of freedom, however, a future application of ALI could be for training purposes, ideally in combination with CLI.
Project description:PurposeFew studies have analyzed the effects of preoperative pain education on the postoperative decision to discharge. The purpose of this study was to determine the effects of pain education and management on the decision to discharge patients after single-incision laparoscopic appendectomy (SILA).MethodsWe analyzed 135 patients who had undergone SILA for acute appendicitis between March 2017 and April 2018 in a single medical center. Of these, 72 patients (53.3%) had received preoperative pain education (group 1), and 63 (46.7%) had not (group 2). We compared perioperative outcomes and complications between the groups.ResultsBaseline characteristics of sex, age, body mass index, American Society of Anesthesiologist score, and systemic inflammation factors (neutrophil-lymphocyte ratio, C-reactive protein level) did not differ significantly between the groups. There were no postoperative complications for patients in either group. Perioperative consequences and pathologic findings were not significantly different between the groups; however, length of hospital was significantly shorter in group 1.ConclusionPreoperative pain education in relation to postoperative pain management influenced the decision to shorten the postoperative hospital length of stay after SILA.
Project description:Single-incision laparoscopic surgery also known as laparo-endoscopic single-site surgery for cholecystectomy is performed using a single umbilical skin incision through which a laparoscope and two instruments are introduced. It is virtually a "scarless" surgery. The present study was undertaken to evaluate the efficacy of single-incision laparoscopic cholecystectomy using conventional instruments and compare it with three-port laparoscopic cholecystectomy. Thirty patients who underwent single-incision cholecystectomy were compared to an equal number of patients who underwent three-port cholecystectomy. Both groups were assessed on the basis of operative time, intraoperative complications, postoperative pain, ambulation, hospital stay, and body image at first and third week. Single-incision cholecystectomy had the advantage of less postoperative pain, early ambulation, and better body image as compared to three-port cholecystectomy; the results being statistically significant. There was no statistically significant difference in operative time and hospital stay between the two groups. Single-incision laparoscopic cholecystectomy using conventional instruments is a safe and effective surgery. It gives better cosmetic results, almost scarless surgery, without increasing the cost of surgery.
Project description:IntroductionSpigelian hernias represent only 1% to 2% of all abdominal wall hernias. The treatment, however, remains controversial but depends on institutional expertise. This case series reports the first experience with single-incision laparoscopic totally extraperitoneal (SILTEP) repair of Spigelian hernias with telescopic extraperitoneal dissection in combination with inguinal hernia repair.MethodsFrom February 2013 to April 2014, all patients referred with inguinal or Spigelian hernias, without histories of extraperitoneal intervention, underwent SILTEP repair with telescopic extraperitoneal dissection. A single-port device, 5.5 mm/52 cm/30° angled laparoscope, and conventional straight dissecting instruments were used for all cases. Extraperitoneal dissection was performed under direct vision with preservation of preperitoneal fascia overlying retroperitoneal nerves. Inguinal herniorrhaphy was performed with lightweight mesh that covered low-lying Spigelian defects. High-lying Spigelian defects were repaired with additional mesh.ResultsThere were 131 patients with 186 (92 direct) inguinal hernias and 7 patients with 8 Spigelian hernias (6 incidental, including 1 bilateral and 2 preoperatively diagnosed), with a mean age of 51.3 years and a mean body mass index of 25.1 kg/m(2). An additional piece of mesh was used for 3 hernias. All Spigelian hernias were associated with direct inguinal hernias, and 8 combined inguinal and Spigelian hernias were successfully repaired with SILTEP repair with telescopic extraperitoneal dissection as day cases. There were no clinical recurrences during a mean follow-up period of 6 months (range, 1-15 months).ConclusionsCombined Spigelian and inguinal hernias can be successfully treated with SILTEP herniorrhaphy with telescopic extraperitoneal dissection. The high incidence of Spigelian hernias associated with direct inguinal hernias suggests a high index of suspicion for Spigelian hernias during laparoscopic inguinal herniorrhaphy.
Project description:Introduction:Single-incision laparoscopic surgery (SILS) has benefits, including less postoperative pain, a shorter incision, and improved cosmesis. However, SILS is technically difficult because of the limited movement. An organ retractor is an instrument that has the potential to overcome these limitations. Presentation of case:An 85-year-old woman with hematochezia was referred to our hospital. Emergency endoscopy showed diverticulosis of the entire colon and active bleeding from the ascending colon. Despite endoscopic clipping, the bleeding continued. SILS total colectomy using an organ retractor was performed due to uncontrollable diverticular bleeding. A 3-cm incision was placed in the umbilicus, and three conventional ports were inserted into the single umbilical incision. An organ retractor was used for hepatocolic ligament transection, transection of the ileocolic vessels, and transection of the mesentery of the sigmoid colon. For each transection, the tension was adjusted to provide a good operative view. The patient's postoperative course was uneventful. Conclusion:An organ retractor was effective for SILS total colectomy to maintain an adequate operative view, which enabled safe dissection.
Project description:BackgroundAppendicitis is a common indication for surgical hospital admission. Uncomplicated appendicitis is typically treated with surgical intervention, most commonly a laparoscopic appendectomy. As with many procedures, narcotic utilization is highly varied among surgeons for postoperative pain control. With the opioid epidemic and a demonstrated link between excessive narcotic prescriptions paving the way to dependence and addiction, it is more important than ever to decrease the circulation of these medications. We hypothesized that a perioperative, multimodal analgesia strategy coupled with monthly feedback reports comparing hospitals narcotic prescribing habits would decrease, and in some cases eliminate, the use of outpatient narcotics in adults after laparoscopic appendectomy.MethodsA quality improvement project was initiated to provide monthly feedback to surgeons on narcotic prescribing habits after adult laparoscopic appendectomies. A multi-hospital database was created to include adult patients that were diagnosed with acute appendicitis, treated with laparoscopic appendectomy, and discharged within 48 h of surgery. The database provided information regarding the number of narcotic doses prescribed on discharge. Participating hospitals selected a site champion who distributed monthly prescribing reports. A protocol was created and distributed to participating sites that provided a guideline for preoperative and postoperative pain medication management. The intervention period was 10/1/2019-3/31/2020. We utilized the preceding year's data (October 1, 2018-September 30, 2019) as the pre-intervention control group. We also compared results between local and distant sites to see if personal connection to surgeons influenced the results.ResultsA total of 1785 appendectomies were performed during the study period at participating hospitals. The average number of prescribed narcotics decreased from 23.6 doses during the control period to 14.2 during the intervention (p < 0.001). There was no change in the number of total narcotic prescriptions (8.9 vs 7.9%, p = 0.52). Overall, the average number of narcotics prescribed decreased by 40% with similar decrease in average prescribed narcotics for local and distant hospitals, respectively (47.7% vs 42.1%). Average narcotic dose during the first 2 months of intervention at the local hospitals was 9.7 and 11.1 for the last 2 months of intervention (p = 0.69). Average narcotic dose during the first 2 months of intervention at the distant hospitals was 19.5 and 13.4 for the last 2 months of intervention (p = 0.005).ConclusionA multimodal pain regimen combined with a monthly narcotic prescription report provided to prescribers decreases the average number of narcotic prescriptions after laparoscopic appendectomy. Local sites demonstrated immediate decrease in narcotic utilization compared to distant sites whose change occurred more gradually.
