Minimally Invasive Surgery最新文献

Laparoscopic cholecystectomy (LC) is one of the highest volume surgeries performed annually. We hypothesized that there is a statistically significant intradepartmental cost variance with supply utilization variability amongst surgeons of different subspecialty. This study sought to describe laparoscopic cholecystectomy cost of care among three subspecialties of surgeons. This retrospective observational cohort study captured 372 laparoscopic cholecystectomy cases performed between June 2015 and June 2016 by 12 surgeons divided into three subspecialties: 2 in bariatric surgery (BS), 5 in acute care surgery (ACS), and 5 in general surgery (GS). The study utilized a third-party software, Surgical Profitability Compass Procedure Cost Manager and Crimson System (SPCMCS) (The Advisory Board Company, Washington, DC), to stratify case volume, supply cost, case duration, case severity level, and patient length of stay intradepartmentally. Statistical methods included the Kruskal-Wallis test. Average composite supply cost per case was $569 and median supply cost per case was $554. The case volume was 133 (BS), 109 (ACS), and 130 (GS). The median intradepartmental total supply cost was $674.5 (BS), $534 (ACS), and $564 (GS) (P<0.005). ACS and GS presented with a higher standard deviation of cost, $98 (ACS) and $110 (GS) versus $26 (BS). The median case duration was 70 min (BS), 107 min (ACS), and 78 min (GS) (P<0.02). The average patient length of stay was 1.15 (BS), 3.10 (ACS), and 1.17 (GS) (P<0.005). Overall, there was a statistically significant difference in median supply cost (highest in BS; lowest in ACS and GS). However, the higher supply costs may be attenuated by decreased operative time and patient length of stay. Strategies to reduce total supply cost per case include mandating exchange of expensive items, standardization of supply sets, increased price transparency, and education to surgeons.

To prevent open surgical procedures, minimally invasive techniques, like Dekompressor (PLDD), have been developed. The absence of reherniation is an important factor correlating with clinical success after lumbar surgery. In this retrospective, observational study, the frequency of additional open surgery after PLDD in a long time retrospective was examined. The correlation between clinical symptoms and outcome was assessed, and the time between PLDD and open surgery was analyzed. Consecutive patients after PLDD between 2005 and 2007 were included. MacNab's outcome criteria were used to evaluate patient satisfaction. The need for additional open surgery of the lumbar spine, the period between Dekompressor and resurgery, and the treated levels were analyzed. In total, 73 patients were included in this study. The patients were seen one month after PLDD. The majority of patients (76.7%) had additional radicular pain. The most common level treated was L4-5 (58.9%). The follow-up time was longer than 5 years in 30.1% of the patients and longer than 10 years in 6.82%. The short-term success rate was 67.1%. Additional surgery was performed in 26.0% of patients, with 78.9% of the reoperations undertaken during the first year after PLDD. These patients had a statistically significant worse outcome (P = 0.025). Radicular pain was present in all patients with an early subsequent surgery, but only in 50% of patients with late surgery (P = 0.035). Significantly more patients with poor pain relief had radicular pain (P = 0.04). The short-term success rate was worsened by a resurgery rate of 26.0%. Subsequent surgery, a short time after PLDD, suggests that PLDD is not a replacement for open discectomy. Because patients with radicular pain had a worse outcome and more frequent resurgeries, whether radicular pain is an ideal indication for PLDD should be discussed.

Objective: To evaluate trends in surgical approach for hysterectomy following the introduction and implementation of a comprehensive robotic surgery program.

Methods: A retrospective review of all hysterectomies done at two institutions, a community hospital and a suburban, tertiary-care teaching hospital, in the same health system over a five-year period, January 2010 through December 2014. A robotic surgery training program was implemented during the first year of the study and trends in route of hysterectomy were evaluated in the subsequent years.

Results: A total of 5175 patients undergoing hysterectomy, for both benign and malignant indications, were included in the study. There was a significant decrease in the percent of cases performed through an abdominal approach at both the community and teaching hospitals (19.3% decline at each institution). There was an inversely related significant increase in the percent of robotic procedures at both the community and teaching hospitals (44.5% and 17%, respectively). A decrease in number of cases performed vaginally over this period was only noted in the community hospital site (25.2% decrease), and there was a slightly higher rate of vaginal hysterectomies at the teaching hospital over this study period (21.9% in 2010, 24.1% in 2014).

Conclusion: The decrease in number of abdominal and laparoscopic hysterectomies and increase in number of robotic hysterectomies that was seen are consistent with national trends. The initiation of a robotic training program did not prevent the proliferation of use of the robot but did aim to ensure proficiency on the robot prior to gaining privileges for patient use. This type of comprehensive training and monitoring program could be applied to future technologic advances to ensure a standard level of surgical proficiency. Trends in route of hysterectomy are clearly multifactorial and involve patient, provider, and location-specific factors that are likely to continue to change.

Background: Undoubtedly, robotic systems have largely penetrated the surgical field. For any new operative approach to become an accepted alternative to conventional methods, it must be proved safe and result in comparable outcomes. The purpose of this study is to compare the short-term operative as well as oncologic outcomes of robotic-assisted and laparoscopic rectal cancer resections.

Methods: This is a prospective randomized clinical trial conducted on patients with rectal cancer undergoing either robotic-assisted or laparoscopic surgery from April 2015 till February 2017. Patients' demographics, operative parameters, and short-term clinical and oncological outcomes were analyzed.

Results: Fifty-seven patients underwent permuted block randomization. Of these patients, 28 were assigned to undergo robotic-assisted rectal surgery and 29 to laparoscopic rectal surgery. After exclusion of 12 patients following randomization, 45 patients were included in the analysis. No significant differences exist between both groups in terms of age, gender, BMI, ASA score, clinical stage, and rate of receiving upfront chemoradiation. Estimated blood loss was evidently lower in the robotic than in the laparoscopic group (median: 200 versus 325 ml, p= 0.050). A significantly more distal margin is achieved in the robotic than in the laparoscopic group (median: 2.8 versus 1.8, p< 0.001). Although the circumferential radial margin (CRM) was complete in 18 patients (85.7%) in the robotic group in contrast to 15 patients (62.5%) in the laparoscopic group, it did not differ statistically (p=0.079). The overall postoperative complication rates were similar between the two groups.

Conclusion: To our knowledge, this is the first prospective randomized trial of robotic rectal surgery in the Middle East and Northern Africa region. Our early experience indicates that robotic rectal surgery is a feasible and safe procedure. It is not inferior to standard laparoscopy in terms of oncologic radicality and surgical complications. Organization number is IORG0003381. IRB number is IRB00004025.

Purposes: Seroma is a postoperative complication following laparoscopic transabdominal preperitoneal repair (TAPP) for inguinal hernioplasty. Seroma naturally resolves in most cases, but it can lead to an increased amount of visits to the outpatient clinic and can result in anxiety of the patient. Local inflammation of the inguinal area is etiology of seroma formation. Strangulated hernia involves severe inguinal pain and can lead to severe inflammation and subsequent seroma. There have been no reports demonstrating the links of seroma and strangulated hernia. This study aimed to retrospectively evaluate the risk of seroma after TAPP and to identify the association between strangulated hernia and seroma.

Methods: We treated 300 inguinal hernias by TAPP between 2013 and 2016 at Kurashiki Central Hospital. We used the Chi-square test. Factors significant in each association were further examined using multiple subsequent logistic regressions.

Results: A total of 222 hernias were eligible for analysis. The incidence of seroma was 11% (n=25). There were nine cases of strangulated hernias, and three (33%) resulted in seroma. The ratio of strangulated hernia of seroma group is significantly high (p<0.03). Multiple subsequent logistic regressions showed that strangulated hernia was associated with a significantly increased risk for seroma formation (p = 0.023; OR 6.564; 95% CI 1.29-33.3).

Conclusion: This study shows that strangulated hernia can be a risk factor in seroma formation. This risk should be incorporated into a management plan of TAPP for strangulated hernia, with careful consideration of patients' concerns.

Introduction: Though, in developed countries, laparoscopy is now a gold standard for splenectomy, we are lacking in this aspect in the eastern world. Splenectomy has mostly been performed by open surgery in our region. This is our effort to introduce laparoscopic splenectomy in our country.

Methods: This is a retrospective cohort study done in patients presenting to hematology and surgery department of our hospital who underwent laparoscopic splenectomy for hematological diseases from January 2013 to December 2016.

Results: There were 50 patients (38 females, 12 males). The diagnoses were idiopathic thrombocytopenic purpura in 31, (steroid/azathioprine-resistant, steroid dependent), hereditary spherocytosis in 9, alpha-thalassemia in 3, beta-thalassemia in 2, autoimmune hemolytic anemia in 4, and isolated splenic tuberculosis in 1. Average platelet counts preoperatively were 62000 ± 11000/mm3 (range 52000-325000/mm3). The mean operative time was 130 ± 49 minutes (range 108-224 min). The mean postoperative stay was 4 ± 2.11 days (range 3-9 days). Laparoscopic splenectomy could be completed in 45 (90%) patients.

Conclusion: Laparoscopic splenectomy could be successfully contemplated in patients with hematological diseases, especially if spleen is normal or only mildly enlarged, and is an advantageous alternative to open splenectomy. Absence of ideal resources has not limited our progress in minimal access approach.

Introduction: Laparoscopic cholecystectomy (LC) is the gold standard treatment for gallstones. British Association of Day Case Surgery recommends at least 60% of LCs be performed as day cases. The aim of this study was to assess our rate of true day case LCs and review factors preventing same-day discharge.

Methods: We prospectively collected data of all elective LCs performed in a district general hospital over 32 months.

Results: 500 patients underwent LC during this period; 438 (88.2%) patients were planned day cases and 59 patients (11.8%) planned overnight stays. Of the planned day cases, 75.8% (n=332) were discharged on the same day and 106 (24.2%) had unexpected overnight stay (UOS). Most patients with BMI >35 and ASA3 planned day case patients were successfully discharged. Drain insertion, longer operations, and late recovery departure were the main reasons for UOS. There were more complications in this group compared to day cases.

Conclusions: This unit has a high 'true day case' rate of 75.8%. High BMI and ASA3 should not be absolute contraindications to day case surgery. The majority of unexpected overnight stays are unavoidable but may be reduced by patient selection, stringent preoperative assessment, operation scheduling, and reduction in unnecessary drain insertion.

Lumbar spinal stenosis has been shown to negatively impact health-related quality of life. Interspinous process decompression (IPD) is a minimally invasive procedure that utilizes a stand-alone spacer to serve as a joint extension blocker to relieve neural compression in patients with spinal stenosis. Using the 5-year results from an FDA randomized controlled trial of IPD, the quality of life in 189 patients treated with the Superion® spacer was evaluated with the SF-12. Physical and mental component summary (PCS, MCS) scores were computed preoperatively and at annual intervals. For the PCS, mean scores improved from 29.4 ± 8.1 preoperatively to 41.2 ± 12.4 at 2 years (40%) and to 43.8 ± 11.6 at 5 years (49%) (p<0.001 for both comparisons). At 2 years, 81% (103 of 128) of subjects demonstrated maintenance or improvement in PCS scores. The mean MCS score improved from 50.0 ± 12.7 preoperatively to 54.4 ± 10.6 and 54.7 ± 8.6 at 2 and 5 years, respectively (p>0.10 for both comparisons). These results demonstrate that the significant impairment in physical well-being found in patients with lumbar spinal stenosis can be ameliorated, in large part, by IPD treatment.

Objective: To study temporal trends of hysterectomy routes performed for uterine cancer and their associations with body mass index (BMI) and perioperative morbidity.

Methods: A retrospective review of the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) 2005-2013 databases was conducted. All patients who were 18 years old and older with a diagnosis of uterine cancer and underwent hysterectomy were identified using ICD-9-CM and CPT codes. Surgical route was classified into four groups: total abdominal hysterectomy (TAH), total vaginal hysterectomy (TVH), laparoscopic assisted vaginal hysterectomy (LAVH), and total laparoscopic hysterectomy (TLH) including both conventional and robotically assisted. Patients were then stratified according to BMI.

Results: 7199 records were included in the study. TLH was the most commonly performed route of hysterectomy regardless of BMI, with proportions of 50.9%, 48.9%, 50.4%, and 51.2% in ideal, overweight, obese, and morbidly obese patients, respectively. The median operative time for TAH was 2.2 hours compared to 2.7 hours for TLH (p < 0.01). The median length of stay for TAH was 3 days compared to 1 day for TLH (p < 0.01). The percentage of patients with an adverse outcome (composite indicator including transfusion, deep venous thrombosis, and infection) was 17.1 versus 3.7 for TAH and TLH, respectively (p < 0.01).

Conclusion: During the last decade, TLH has been increasingly performed in women with uterine cancer. The increased adoption of TLH was seen in all BMI subgroups.

Introduction: Laparoscopic inguinal hernia repair (LIHR) is ideal for day case surgery. It is recommended that at least 70% should be day cases as a measure of cost-effectiveness. The aims of this study were to (i) assess the rate of true day case (TDC) surgery and (ii) identify predictors associated with unexpected overnight stay (UOS).

Methods: Data was collected prospectively on 1000 consecutive elective LIHR performed in a District General Hospital (DGH) over a 7-year period. Data was collected on baseline patient demographics, ASA grade, and intraoperative details. A multivariate analysis was performed in order to identify predictors of UOS.

Results: 1000 patients (927 males) underwent elective LIHR. Mean age was 57.3±15.2 years. 915 patients were planned as day case procedures. 822/915 day cases (89.8%) were discharged on the same day and 93 (10.2%) stayed overnight unexpectedly. Patient age, duration of procedure, and patient slot in the operating list were found to be independent predictors (p<0.05) of UOS.

Conclusion: Our results demonstrate that LIHR is a "true" day case procedure in a DGH. Although some factors associated with UOS cannot be altered, careful patient selection and operating list planning are of paramount importance in order to minimise the burden on healthcare resources.
