Background:The aim of this study is to compare the safety and efficacy of conventional laparotomy with those of robotic and laparoscopic approaches to hepatectomy.Database:Independent reviewers conducted a systematic review of publications in PubMed and Embase, with searches limited to comparative articles of laparoscopic hepatectomy with either conventional or robotic liver approaches. Outcomes included total operative time, estimated blood loss, length of hospitalization, resection margins, postoperative complications, perioperative mortality rates, and cost measures. Outcome comparisons were calculated using random-effects models to pool estimates of mean net differences or of the relative risk between group outcomes. Forty-nine articles, representing 3702 patients, comprise this analysis: 1901 (51.35%) underwent a laparoscopic approach, 1741 (47.03%) underwent an open approach, and 60 (1.62%) underwent a robotic approach. There was no difference in total operative times, surgical margins, or perioperative mortality rates among groups. Across all outcome measures, laparoscopic and robotic approaches showed no difference. As compared with the minimally invasive groups, patients undergoing laparotomy had a greater estimated blood loss (pooled mean net change, 152.0 mL; 95% confidence interval, 103.3–200.8 mL), a longer length of hospital stay (pooled mean difference, 2.22 days; 95% confidence interval, 1.78–2.66 days), and a higher total complication rate (odds ratio, 0.5; 95% confidence interval, 0.42–0.57).Conclusion:Minimally invasive approaches to liver resection are as safe as conventional laparotomy, affording less estimated blood loss, shorter lengths of hospitalization, lower perioperative complication rates, and equitable oncologic integrity and postoperative mortality rates. There was no proven advantage of robotic approaches compared with laparoscopic approaches. 相似文献

Minimally invasive surgery, which has been extensively used to treat gastric adenocarcinoma, is now regarded as one of the standard treatments for early gastric cancer, and its suitability for advanced gastric cancer is being investigated. The use of cutting-edge techniques for minimally invasive surgery enables surgeons to deliver various treatment options to minimize a patient''s distress and to maintain oncologic safety. Ongoing multicenter prospective studies aim to validate the efficacy of these surgical techniques and to expand the indications of minimally invasive surgery for the treatment of gastric cancer. In this review, we summarize the current status and issues regarding minimally invasive surgery for the treatment of gastric cancer. 相似文献

Background
Perioperative short-term outcomes could be improved after totally robotic Roux-en-Y gastric bypass (TR-RYGBP) compared with conventional laparoscopic gastric bypass.Methods
This is a nonrandomized controlled prospective study (N = 200) to evaluate perioperative short-term outcomes. The primary endpoint was to investigate risk factors for 30-day surgical complications.Results
Mean total operative time was shorter in patients who underwent TR-RYGBP (130 vs 147 minutes; P < .0001). However, postoperative surgical complications rate (13% vs 1%; P = .001), and mean overall hospital stay (9.3 vs 6.7 days; P < .0001) were higher after TR-RYGBP. By multivariate analysis, robotic surgery (hazard ratio [HR] = 15.1; 95% confidence interval [CI], 2.8 to 280; P = .01), and conversion to laparotomy (HR = 18.8; 95% CI, 1.7 to 250.8; P = .014) were independent risk factors for 30-day surgical complications.Conclusions
Although robotic gastric bypass reduces mean operative time, TR-RYGBP is associated with an increased postoperative surgical complications rate and longer hospitalization. 相似文献15.

Objectives:
The primary objective was to examine the safety and feasibility of robotic-assisted laparoscopy in a cohort of women treated surgically for stage III and IV endometriosis. The secondary objective was to explore whether the stage of endometriosis affected surgical outcome.Methods:
In this cohort study, 43 women with severe endometriosis were treated with robot-assisted laparoscopic hysterectomy with unilateral or bilateral salpingo-oophorectomy for stage III (n = 19) or stage IV (n = 24) disease.Results:
Histopathologic evaluation confirmed endometriosis in all patients, and fibroids were also shown in 12 patients. The median actual operative time was 145 min (range, 67–325 min), and the median blood loss was 100 mL (range, 20–400 mL). All but one of the procedures were completed successfully robotically. The length of hospital stay was 1 d for 95% of patients (41 of 43), and 2 patients had prolonged stays of 4 d and 5 d, respectively. One patient was readmitted for a vaginal cuff abscess; this represented the only complication identified in this series.Conclusions:
Robot-assisted laparoscopic surgery appears to be a reasonably safe and feasible method for the definitive surgical management of women with severe endometriosis. 相似文献16.

IntroductionThe paradoxical benefit of obesity, the ‘obesity paradox’, has been analyzed in lung surgical populations with contradictory results. Our goal was assessing the relationship of body mass index (BMI) to acute outcomes after minimally invasive major pulmonary resections.MethodsRetrospective review of consecutive patients who underwent pulmonary anatomical resection through a minimally invasive approach for the period 2014–2019. Patients were grouped as underweight, normal, overweight and obese type I, II and III. Adjusted odds ratios regarding postoperative complications (overall, respiratory, cardiovascular and surgical morbidity) were produced with their exact 95% confidence intervals. All tests were considered statistically significant at p < 0.05.ResultsAmong 722 patients included in the study, 37.7% had a normal BMI and 61.8% were overweight or obese patients. When compared with that of normal BMI patients, adjusted pulmonary complications were significantly higher in obese type I patients (2.6% vs 10.6%, OR: 4.53 [95%CI: 1.86–12.11]) and obese type II–III (2.6% vs 10%, OR: 6.09 [95%CI: 1.38–26.89]). No significant differences were found regarding overall, cardiovascular or surgical complications among groups.ConclusionsObesity has not favourable effects on early outcomes in patients undergoing minimally invasive anatomical lung resections, since the risk of respiratory complications in patients with BMI ≥ 30 kg/m2 and BMI ≥ 35 kg/m2 is 4.5 and 6 times higher than that of patients with normal BMI. 相似文献

Background
We recently reported on preclinical and feasibility studies (Innovation, Development, Exploration, Assessment, Long-term study [IDEAL] phase 0–1) of the development of robotic kidney transplantation (RKT) with regional hypothermia. This paper presents the IDEAL phase 2a studies of technique development.Objectives
To describe the technique of RKT with regional hypothermia developed at two tertiary care institutions (Vattikuti Urology Institute and Medanta Hospital). We report on the safety profile and early graft function in these patients.Design, setting, and participants
This is a prospective study of 50 consecutive patients who underwent live-donor RKT at Medanta Hospital following a 3-yr planning/simulation phase at the Vattikuti Urology Institute. Demographic details, and perioperative and postoperative outcomes are reported for the initial 25 recipients who have completed a minimum 6-mo follow-up.Surgical procedure
Positioning and port placement were similar to that used for robotic radical prostatectomy. Allograft cooling was achieved by ice slush delivered through a GelPOINT device. The accompanying video details the operative technique.Outcome measurements and statistical analysis
The primary outcome was posttransplant graft function. Secondary outcomes included technical success or failure and complication rates.Results and limitations
Fifty patients underwent RKT successfully, 7 in the phase 1 and 43 in the phase 2 stages of the study. For the initial 25 patients, mean console, warm ischemia, arterial, and venous anastomotic times were 135, 2.4, 12, and 13.4 min, respectively. All grafts were cooled to 18–20°C with no change in core body temperature. All grafts functioned immediately posttransplant and the mean serum creatinine level at discharge was 1.3 mg/dl (range: 0.8–3.1 mg/dl). No patient developed anastomotic leaks, wound complications, or wound infections. At 6-mo of follow-up, no patient had developed a lymphocele detected on CT scanning. Two patients underwent re-exploration, and one patient died of congestive heart failure (1.5 mo posttransplant).Conclusions
RKT with regional hypothermia is safe and reproducible when performed by a team skilled in robotic surgery.Patient summary
RKT is safe and effective when performed by surgeons experienced in robotic techniques. 相似文献20.
