Outcomes of Robotic Living Donor Right Hepatectomy from 52 Consecutive Cases: Comparison with Open and Laparoscopy-assisted Donor Hepatectomy

OBJECTIVE To investigate the feasibility and safety of RLDRH SUMMARY OF BACKGROUND DATA:: Data for minimally invasive living-donor right hepatectomy, especially RLDRH, from a relatively large donor cohort that have not been reported yet. METHODS From March 2016 to March 2019, 52 liver donors underwent RLDRH. The clinical and perioperative outcomes of RLDRH were compared with those of CODRH (n = 62) and LADRH (n = 118). Donor satisfaction with cosmetic results was compared between RLDRH and LADRH using a body image questionnaire. RESULTS Although RLDRH was associated with longer operative time (minutes) (RLDRH, 493.6; CODRH, 404.4; LADRH, 355.9; P < 0.001), mean estimated blood loss (mL) was significantly lower (RLDRH, 109.8; CODRH, 287.1; LADRH, 265.5; P = 0.001). Postoperative complication rates were similar among the 3 groups (RLDRH, 23.1%; CODRH, 35.5%; LADRH, 28.0%; P = 0.420). Regarding donor satisfaction, body image and cosmetic appearance scores were significantly higher in RLDRH than in LADRH. After propensity score matching, RLDRH showed less estimated blood loss compared to those of CODRH (RLDRH, 114.7 mL; CODRH, 318.4 mL; P < 0.001), but complication rates were similar among the three groups (P = 0.748). CONCLUSIONS RLDRH resulted in less blood loss compared with that of CODRH and similar postoperative complication rates to CODRH and LADRH. RLDRH provided better body image and cosmetic results compared with those of LADRH. RLDRH is feasible and safe when performed by surgeons experienced with both robotic and open hepatectomy.

Complete mesocolic excision versus conventional hemicolectomy in patients with right colon cancer: a systematic review and meta-analysis.

Complete mesocolic excision (CME) has introduced a promising surgical approach for treatment of right colon cancer. However, benefits of CME are still a matter of debate. We conducted a systematic review and meta-analysis to assess safety and long-term outcomes of CME versus conventional right hemicolectomy (CRH). We systematically searched MEDLINE, the Cochrane Database of Systematic Reviews, Scopus, Web of Science, and Embase for retrieving studies comparing CME with CRH in right colon cancer. After data extraction from the included studies, meta-analysis was performed to compare postoperative complications, anastomotic leakage, 30-day mortality, number of lymph node yield, disease-free survival (DFS), and overall survival (OS). Eight studies met the inclusion criteria with a total of 1871 patients enrolled. No difference was observed in postoperative complications (OR 1.13, 95% CI 0.88-1.47, p = 0.34). CME was associated with significantly higher number of lymph nodes retrieved (MD 9.17, CI 4.67-13.68, p < 0.001). CME also improved 3-year OS (OR 1.57, 95% CI 1.17-2.11, p = 0.003), 5-year OS (OR 1.41, 95% CI 1.06-1.89, p = 0.02), and 5-year DFS (OR 1.99, 95% CI 1.29-3.07, p = 0.002). A sub-group analysis for patients with stage III colon cancer showed no significant impact of CME on 3-year and 5-year OS (OR 2.47, 95% CI 0.86-7.06, p = 0.09; OR 1.23, 95% CI 0.78-1.94, p = 0.38). Although with limited evidence, CME shows similar postoperative complication rates and an improved survival outcome compared with CRH.

Comparison of percutaneous dilatational tracheotomy versus open surgical technique in severe COVID-19: Complication rates, relative risks and benefits

ObjectivePatients with acute respiratory failure due to COVID-19 have a high likelihood of needing prolonged intubation and may subsequently require tracheotomy. Usually, the choice of technique (percutaneous dilatational tracheotomy [PDT] versus open surgical tracheotomy [OST]) depends on the preference of surgeons and patient-related factors. In case of COVID-19, airborne spread of viral particles and limited time of apnea must be considered in the choice of the safest technique. The aim of this study is to compare the complication rates and offer an assessment of relative risks and benefits of PDT versus OST in patients with severe COVID-19. MethodsWe performed a retrospective study considering 47 consecutive patients affected by severe acute respiratory distress syndrome due to SARS-CoV-2 infection, needing invasive mechanical ventilation and subsequent tracheostomy. This study was performed at the Intensive Care Unit of our tertiary referral center. Complication rates were analyzed. ResultsSeventeen patients underwent PDT and 30 patients were submitted to OST. Twenty-six patients (55.3%) had post-operative complications (local infection, hemorrhage, subcutaneous emphysema) with no significant difference between PDT and OST. ConclusionPDT and OST are characterized by similar postoperative complication rates in severe COVID-19 patients. These findings suggest that OST might be preferred if expert ENT surgeons are available, as PDT could result in longer apnea and exposure to generated aerosol. However, authors recommend considering either OST or PDT at the discretion of the medical staff involved, according to the personal experience of the operators performing the procedure.

The value of an additional scrotal suture during orchidopexy

Undescended testes present in 3-5% of male infants at birth. Orchidopexy is indicated to improve fertility and reduce the risk of testicular tumors. Guidelines recommend orchidopexy as early as six months of age, treatment should be finished within the age of 18 months. So far, no unequivocal proof demonstrated the superiority of one of the different surgical techniques. To evaluate the value of an additional scrotal suture between the tunica albuginea and the dartos fascia during orchidopexy in an outpatient setting. It is yet unclear, whether the suture influences the incidence of secondary cryptorchidism or recurrence. This is a retrospective cohort study. Between 2010 and 2018 two experienced surgeons performed 561 inguinal orchidopexy-procedures in an open technique (375 boys). In group 1 (2010-2014) they managed 234 IOP (156 boys) without an additional scrotal suture. Since 2014, in group 2 an additional suture has been performed in 327 IOP (219 boys). Statistically, we compared both groups over a period of consecutive 4 years after the model of a life table analysis (Logrank). The numbers of boys with complete follow-up were 118 of 156 in group 1 and 154 of 219 in group 2, demonstrating 7 (5.9%) and 7 (4.5%) recurrences, respectively. There was no statistically significant difference in recurrences between group 1 and group 2 (Logrank-Test, p=0.97). Orchidopexie failure was detected between 0.9 and 23.1 months after the IOP in group 1 and between 3.2 and 17.7 months in group 2. Mean age in months at the operation in both groups was significantly higher than the recommended 6-18 months in the EAU/AUA-guidelines. Both groups showed similar rates of postoperative complications. Orchidopexy is a safe procedure in an outpatient setting. So far there is no evidence that performing an additional scrotal suture decreases the operative failure rate in inguinal standard orchidopexy procedures.

Complications Rates and Outcomes Following First Metatarsophalangeal Arthrodesis for Hallux Rigidus: Does Age Matter?

Category:Midfoot/Forefoot; OtherIntroduction/Purpose:Hallux rigidus is one of the most common toe pathologies in patients greater than 50 years old. While first metatarsophalangeal (MTP) arthrodesis is utilized to improve pain and function, older patients are often considered to be higher risk surgical candidates. There are minimal data on outcomes of MTP arthrodesis and no studies comparing outcomes between geriatric and younger patients.Methods:This is a single center, prospective study of all patients who underwent MTP arthrodesis between August 1, 2015 and July 1, 2018. Patient reported-outcomes were assessed utilizing the Short Form Health survey (SF-36), LifeSpace Assessment survey (LSA), and visual analogue scale (VAS) for pain administered preoperatively as well as 6-months and 1-year postoperatively. Baseline characteristics and surgical outcomes were collected from the electronic medical record. All operations were performed by one foot and ankle fellowship-trained orthopedic surgeon. Clinical and patient-reported outcomes were compared between patients <65 years-old and ≥ 65 years-old.Results:Of 143 included patients, 79 were placed in the younger (mean of 56.5 years) and 64 were in the older (mean of 72.0 years) cohorts. Compared to the younger cohort, the older was more predominantly female (95.3% older group, 77.2% younger group, p=0.002). More patients in the older cohort had hypertension (73.4% older group, 50.6% younger group, p=0.005) and coronary artery disease (9.4% older group, 0.0% younger group, p= 0.005). Both age groups had similar postoperative outcomes, including antibiotic therapy for superficial infections, surgical incision and drainage, deep vein thrombosis, deformity recurrence, or revision surgery. No differences were detected in SF-36, LSA, and VAS surveys administered at baseline, 6-months postoperative, or 1-year postoperative between younger and older patients.Conclusion:Despite more comorbidities, older patients have similar rates of postoperative complications and report similar outcomes for pain, function, and mobility following first MTP arthrodesis. These findings support increased implementation of MTP arthrodesis surgery for older patients with hallux rigidus.

Safety Profile of Artelon Use for Soft Tissue Reconstruction in Foot and Ankle Surgery

Category:Basic Sciences/Biologics; Ankle; Hindfoot; Midfoot/Forefoot; SportsIntroduction/Purpose:Artelon is a synthetic degradable polyurethaneurea graft which has been investigated and utilized for soft tissue reconstruction in a variety of orthopaedic settings. However, in the field of foot and ankle surgery, there is very limited reported clinical data on outcomes of surgery utilizing Artelon. The goal of this study was look at outcomes of foot and ankle surgery in which Artelon is used, including post-op VAS scores and complications including adverse foreign body reaction, infection, repeat surgery, and implant failure. Our hypothesis was that soft tissue reconstruction procedures utilizing artelon will have a low complication rate, similar to established complication rates for other soft tissue reconstruction procedures such as those utilizing allograft, autograft, or other synthetic tissue.Methods:The treating surgeon’s first 55 consecutive patients 18 years and older who were treated with artelon graft as part of a foot and ankle surgery are being included in this IRB-approved study. Through retrospective chart review, outcome measures including the procedure for which artelon was utilized, pre and post-op Visual Analogue Scale (VAS) scores, and complications including repeat surgery for graft failure, foreign body reaction, wound healing issues, infection, and osteolysis were assessed.Statistical analysis was done utilizing Student’s t-test for continuous variables and chi square test for categorical variables.Results:Average follow-up time was 246.5 days. The majority of patients had artelon placed for spring ligament reconstruction, brostrom procedures, or achilles tendon reconstruction. VAS scores dropped significantly from before surgery to 3 weeks post- operatively (5.6 to 3.2, p<0.05). VAS scores stabilized after 3 weeks, with final follow-up score at 2.9. There were no reports of osteolysis in the area of the graft placement, adverse foreign body reaction, or episodes of graft failure. There were two major complications involving artelon surgical sites: one patient required a free flap for wound coverage, and another required an operative debridement with hardware and artelon removal, antibiotic spacer placement, and subsequent hindfoot fusion. Other minor complications not requiring operative intervention included cellulitis (3 patients) and delayed wound healing (5).Conclusion:Artelon is a safe and effective implant that can be utilized for soft tissue reconstruction in the foot and ankle, with similar post-operative pain recovery and wound complication rates compared to established historical data for these procedures. Additional studies must be done looking at long-term patient outcomes with utilization of artelon, and direct comparative studies with other soft tissue reconstruction techniques and materials in the foot and ankle.

Long-term abdominal wall benefits of the laparoscopic approach in liver left lateral sectionectomy: a multicenter comparative study.

Laparoscopy is nowadays considered as the standard approach for hepatic left lateral sectionectomy (LLS), but its value in the prevention of incisional hernia (IH) has not been demonstrated. Between 2012 and 2017, patients undergoing laparoscopic (LLLS) or open LLS (OLLS) in 8 centers were compared. Patients undergoing a simultaneous major abdominal procedure were excluded. The incidence of IH was assessed clinically and morphologically on computed tomography (CT) using inverse probability of treatment weighting (IPTW) and multivariable regression analysis. After IPTW, 84 LLLS were compared to 48 OLLS. Compared to OLLS, LLLS patients had reduced blood loss (100 [IQR: 50-200] ml vs. 150 [IQR: 50-415] ml, p = 0.023) and shorter median hospital stay (5 [IQR: 4-7] days vs. 7 [6-9] days, p < 0.001), but experienced similar rate of postoperative complications (mean comprehensive complication index: 12 ± 19 after OLLS versus 13 ± 20 after LLLS, p = 0.968). Long-term radiological screening was performed with a median follow-up of 27.4 (12.1-44.9) months. There was no difference between the two groups in terms of clinically relevant IH (10.7% [n = 9] after LLLS, 8.3% [n = 4] after OLLS, p = 0.768). The rate of IH detected on computed tomography was lower after LLLS than after OLLS (11.9% [n = 10] versus 29.2% [n = 14], p = 0.013). On multivariable analysis, the laparoscopic approach was the only independent factor influencing the risk of morphological IH (OR = 0.290 [95% CI: 0.094-0.891], p = 0.031). The 2 preferential sites for specimen extraction after LLLS were Pfannenstiel and midline incisions, with rates of IH across the extraction site of 2.3% [n = 1/44] and 23.8% [n = 5/21], respectively (p = 0.011). The laparoscopic approach for LLS decreases the risk of long-term IH as evidenced on morphological examinations, with limited clinical impact. Pfannenstiel's incision should be preferred to midline incision for specimen extraction after LLLS.

Middle Cranial Fossa Approach to Vestibular Schwannoma Resection in the Older Patient Population.

Compare outcomes of middle cranial fossa approach (MCF) to vestibular schwannoma (VS) resection in patients 60 years of age and older to patients under 60. Retrospective case series. Tertiary referral center. Charts of 216 consecutive VS patients over 18 years of age were reviewed to identify 67 patients who underwent MCF approach to VS resection between 2006 and 2017. Age at time of surgery. Measured outcomes included postoperative hearing results, facial nerve function, length of hospital stay, wound complications, cerebrospinal fluid leak, myocardial infarction, cerebrovascular accident, seizure, deep vein thrombosis, 30-day readmission, and return to operating room. Sixty-seven patients underwent VS resection via MCF approach including 16 patients > = 60 years (mean 64.4 SD 3.3) and 51 patients < 60 years (mean 45.7 SD 10.2). Between these two groups, there were no differences in sex, tumor laterality, tumor size (10.4 mm versus 9.8 mm, p = 0.6), or other demographic characteristics. Postoperatively, there were no differences between groups in complication rates. Rates of HB 1 or 2 facial nerve function were similar (93.8% versus 88.2%, p = 0.7) as were rates of maintenance of class A or B hearing (58.3% versus 44.4%, p = 0.7). Patients over 60 undergoing MCF for VS resection experienced similar rates of postoperative complications, facial nerve outcomes, and hearing preservation compared with younger patients. MCF for VS may be considered in the older population. Further research is warranted to evaluate appropriate limitations for this approach based on age.

P136. Clinical and radiographic outcomes after lumber decompression with placement of interlaminar spacers versus decompression alone

BACKGROUND CONTEXT Lumbar decompression is a viable treatment option for spinal stenosis with neurogenic claudication that has failed conservative treatment. However, given the relatively high rates of reoperation with decompression alone (up to 23%) and the increased surgical burden associated with fusion, alternative stabilization techniques such as dynamic interlaminar spacers have been utilized with the goal of providing stabilization while also preserving motion and native biomechanics. PURPOSE The purpose of this study is to evaluate whether interlaminar spacers can effectively augment lumbar decompression in the treatment of symptomatic spinal stenosis. STUDY DESIGN/SETTING Retrospective cohort study at a single institution. PATIENT SAMPLE Ninety-seven patients were included for analysis. Forty-three of these patients underwent lumbar decompression with placement of an interlaminar spacer, and 54 underwent lumbar decompression alone. OUTCOME MEASURES Radiographic parameters: anterior disc height, posterior disc height, segmental alignment, lumbar lordosis, lumbar range of motion, and foraminal height were measured before and after surgery. Outcome measures such as complication rates, and reoperation rates were also compared between the two cohorts. METHODS This is a retrospective cohort study at a single institution between January 2013 and November 2016. Ninety-seven patients were included for analysis. Forty-three of these patients underwent lumbar decompression with placement of an interlaminar spacer, and 54 underwent lumbar decompression alone. Radiographic parameters such as anterior disc height, posterior disc height, segmental alignment, lumbar lordosis, lumbar range of motion, and foraminal height were measured before and after surgery. Outcome measures, complication rates, and reoperation rates were also compared between the two cohorts. RESULTS Patients in the interlaminar spacer cohort had a significant increase in mean posterior disc height (4.5 to 5.1, p = 0.04) and decrease in mean anterior disc height (9.2 to 8.5 mm, p = 0.02). No significant anterior or posterior disc height change occurred in the laminectomy alone cohort. Both groups had a statistically significant decrease in segmental lumbar lordosis, although there was no observed difference in this degree of change between the two groups and no change in overall lumbar lordosis from L1-S1 in either cohort. Both cohorts demonstrated significant improvement in both Visual Analog Scores (VAS) and Oswestry Disability Index (ODI) postoperatively. The two cohorts had similar rates of postoperative complications, and the interlaminar spacer group had a slightly lower rate of reoperation (11.6% vs 20.4%, p = 0.28). CONCLUSIONS These results indicate that lumbar decompression supplemented with interlaminar spacers can lead to substantial improvement in both clinical and radiographic outcomes. We also found that the interlaminar spacer cohort had similar rates of complications and a lower reoperation rate, which deviates from previously published studies that demonstrate a substantially higher complication rate with interlaminar spacers.

OUTCOMES OF ROBOTIC LIVING DONOR RIGHT HEPATECTOMY FROM 52 CONSECUTIVE CASES: COMPARISON WITH OPEN AND LAPAROSCOPY-ASSISTED DONOR HEPATECTOMY

OBJECTIVE To investigate the feasibility and safety of RLDRH SUMMARY OF BACKGROUND DATA:: Data for minimally invasive living-donor right hepatectomy, especially RLDRH, from a relatively large donor cohort that have not been reported yet. METHODS From March 2016 to March 2019, 52 liver donors underwent RLDRH. The clinical and perioperative outcomes of RLDRH were compared with those of CODRH (n = 62) and LADRH (n = 118). Donor satisfaction with cosmetic results was compared between RLDRH and LADRH using a body image questionnaire. RESULTS Although RLDRH was associated with longer operative time (minutes) (RLDRH, 493.6; CODRH, 404.4; LADRH, 355.9; P < 0.001), mean estimated blood loss (mL) was significantly lower (RLDRH, 109.8; CODRH, 287.1; LADRH, 265.5; P = 0.001). Postoperative complication rates were similar among the 3 groups (RLDRH, 23.1%; CODRH, 35.5%; LADRH, 28.0%; P = 0.420). Regarding donor satisfaction, body image and cosmetic appearance scores were significantly higher in RLDRH than in LADRH. After propensity score matching, RLDRH showed less estimated blood loss compared to those of CODRH (RLDRH, 114.7 mL; CODRH, 318.4 mL; P < 0.001), but complication rates were similar among the three groups (P = 0.748). CONCLUSIONS RLDRH resulted in less blood loss compared with that of CODRH and similar postoperative complication rates to CODRH and LADRH. RLDRH provided better body image and cosmetic results compared with those of LADRH. RLDRH is feasible and safe when performed by surgeons experienced with both robotic and open hepatectomy.

Guidelines Adaptation to the COVID-19 Outbreak for the Management of Hepatocellular Carcinoma.

Background: COVID-19 pandemic rendered the surgical approach as well as the surgical indication very complex due to the outstanding consumption of public health system' resources, especially in the intensive care subdivision. A multidisciplinary team-based strategy is necessary to adapt guidelines and medical practices to the actual situation. The aim of this study is to evaluate the changes in the therapeutic algorithm in a small group of patients with hepatocellular carcinoma (HCC) enlisted for surgery during the COVID-19 outbreak. Materials and Methods: A multidisciplinary strategy has been adopted to allocate HCC patients to a treatment that permitted to reduce the risk of complications and the hospital stay, thus preventing contamination by the virus. Nasopharyngeal swab and a chest radiograph were performed in all patients within 48 hours before the surgical procedure: in the suspected cases with negative COVID tests, we prudently postponed surgery and repeated the diagnostic tests after 15 days. Results: During the emergency state, 11 HCC patients were treated (8 laparoscopic ablations and 3 hepatic resections). We reported only 1 postoperative complication (hemothorax) and 1 death during the follow-up for COVID pneumonia. Comparing our performances with those in the same time frame in the past 4 years, we treated a similar number of HCC patients, obtaining a decrease in operative timing (P = .0409) and hospital stay (P = .0412) (Fig. 2b) with similar rates of immediate postoperative complications, without ICU admissions. Conclusions: An adapted algorithm for the treatment of HCC to COVID outbreak permitted to manage safely these patients by identifying those most at risk of evolution of the neoplastic disease.

Predictors of mortality following emergency open colectomy for ischemic colitis: a single-center experience

BackgroundIschemic colitis (IC) is a severe emergency in gastrointestinal surgery. The aim of the present study was to identify the predictors of postoperative mortality after emergent open colectomy for IC treatment. Additionally, we compared postoperative outcomes of patients undergoing emergent colectomy due to aortic surgery-related IC (AS-IC group) vs. other IC etiologies (Other-IC group).MethodsWe analyzed records of consecutive patients who underwent emergency open colectomy for IC between 2008 and 2019. Logistic regression analysis was performed to identify clinical and operative parameters associated with postoperative mortality. The AS-IC and Other-IC groups were compared for mortality, morbidity, ICU stay, hospital stay, and survival.ResultsDuring the study period, 94 patients (mean age, 67.4 ± 13.7 years) underwent emergent open colectomy for IC. In the majority of cases, IC involved the entire colon (53.2%) and vasopressor agents were required preoperatively (63.8%) and/or intraoperatively (78.8%). Thirty-four patients underwent surgery due to AS-IC, whereas 60 due to Other-IC causes. In the AS-IC group, 9 patients had undergone endovascular aortic repair and 25 open aortic surgery; 61.8% of patients needed aortic surgery for ruptured abdominal aortic aneurism (AAA). Overall, 66 patients (70.2%) died within 90 days from surgery. The AS-IC and Other-IC groups showed similar operative outcomes and postoperative complication rates. However, the duration of the ICU stay (19 days vs. 11 days; p = 0.003) and of the total hospital stay (22 days vs. 16 days; p = 0.016) was significantly longer for the AS-IC group than for the Other-IC group. The rate of intestinal continuity restoration at 1 year after surgery was higher for the Other-IC group than for the AS-IC group (58.8% vs. 22.2%; p = 0.05). In the multivariate model, preoperative increased lactate levels, a delay between signs/symptoms’ onset and surgery > 12 h, and the occurrence of postoperative acute kidney injury were statistically associated with postoperative mortality. Neither IC etiology (aortic surgery vs. other etiology) nor ruptured AAA was associated with postoperative mortality.ConclusionEmergency open colectomy for IC is associated with high postoperative mortality, which appears to be unrelated to the IC etiology. Preoperative lactate levels, > 12-h delay to surgery, and postoperative acute kidney injury are independent predictors of postoperative mortality.

Managing Malperfusion Syndrome in Acute Type A Aortic Dissection With Previous Cardiac Surgery

Patients with acute type A aortic dissection with a previous cardiac surgery (PCS) and malperfusion syndrome (MPS) are extremely difficult to manage and have poor outcomes. From 1996 to 2018, 668 patients underwent emergent open aortic repair or endovascular fenestration/stenting for MPS for an acute type A aortic dissection, including those with PCS (PCS, n= 64) and those without PCS (No-PCS, n= 604). The groups were further divided into PCS+MPS, PCS+No-MPS, No-PCS+MPS, and No-PCS+No-MPS. Compared with the No-PCS group, the PCS group had significantly more coronary artery disease, acute renal failure, and mesenteric and renal MPS. Forty-two percent of patients with PCS underwent upfront endovascular fenestration/stenting for endovascular-amendable MPS. The in-hospital mortality was significantly higher in patients with PCS+MPS (40%) compared with PCS+No-MPS (5.9%), No-PCS+MPS (30%), and No-PCS+No-MPS (6.7%). Multivariable logistic regression showed cardiogenic shock (odds ratio, 7.3) and MPS (odds ratio, 6.6) were risk factors for in-hospital mortality (P < .001). After recovering from MPS the PCS group (n= 54) had similar rates of postoperative complications, including 30-day mortality (7.4% vs 6.3%, P= .77), compared with the No-PCS group (n= 557). The 5-year survival was significantly lower in the PCS group compared with the No-PCS group (60% vs 72%, P= .004) and was lowest in those with PCS+MPS (46%). PCS was not a significant risk factor for in-hospital (odds ratio, 1.2; P= .63) or late (hazard ratio, 1.3; P= .27) mortality. Because of severe preoperative comorbidities and the complexity of open aortic repair, in acute type A aortic dissection patients with PCS and MPS, endovascular fenestration and stenting first with delayed redo sternotomy and central aortic repair was a valid approach.

Perioperative and oncological outcomes of laparoscopic radical cystectomy with intracorporeal versus extracorporeal ileal conduit: A matched-pair comparison in a multicenter cohort in Japan.

To compare the perioperative and oncological outcomes of pure laparoscopic intracorporeal ileal conduit urinary diversion versus extracorporeal ileal conduit urinary diversion after laparoscopic radical cystectomy for bladder cancer in a multicenter cohort in Japan. A total of 455 patients who underwent laparoscopic radical cystectomy carried out at 10 institutions were included in this retrospective study. The perioperative data of the intracorporeal ileal conduit urinary diversion and extracorporeal ileal conduit urinary diversion groups were compared using the propensity score matching method. The Kaplan-Meier curves were obtained to elucidate time to ureteroenteric stricture, reoperation, recurrence and survival. In total, 72 matched pairs were evaluated for the final analysis. The median follow-up period was 28 and 23months in the intracorporeal ileal conduit urinary diversion and extracorporeal ileal conduit urinary diversion groups, respectively. The operative time in the intracorporeal ileal conduit urinary diversion group was approximately 1h longer than that in the extracorporeal ileal conduit urinary diversion group. The early and late postoperative complication rates were similar in both groups, except for the reduced wound-related complication rates in the intracorporeal ileal conduit urinary diversion group. The median days to regular oral food intake were 4 and 5days in the intracorporeal ileal conduit urinary diversion and extracorporeal ileal conduit urinary diversion groups, respectively (P=0.014). No significant difference was noted in the occurrence of ureteroenteric strictures and reoperation rate. Furthermore, recurrence-free, cancer-specific, and overall survival rates and recurrence patterns did not significantly differ. Laparoscopic intracorporeal ileal conduit urinary diversion is a safe, feasible and reproducible procedure with similar postoperative complication rates, ureteroenteric stricture rate and oncological outcomes when compared with extracorporeal ileal conduit urinary diversion, but faster postoperative bowel recovery and decreased wound-related complication rates.

Endoscopic Mitral Repair for Degenerative Mitral Regurgitation: Effect of Disease Complexity on Short- and Mid-term Outcomes

BackgroundWe set out to compare in a prospective cohort study the mid-term clinical and echocardiographic outcomes of mini-mitral repair for simple (posterior prolapse) vs complex regurgitation (anterior/bileaflet prolapse). MethodsA total of 245 consecutive patients underwent mini-mitral repair for severe degenerative mitral regurgitation through a right, endoscopic approach (n = 145 simple, n = 100 complex). The most common repair technique was annuloplasty + artificial chordae (84%, n = 121 for simple vs 88%, n = 88 for complex, P = 0.3). Patients were prospectively followed for a maximal duration of 9 years. Patients’ characteristics were well balanced between groups. ResultsThe 30-day/in-hospital mortality was similar (0%, n = 0 simple vs 1%, n = 1 complex, P = 0.2). Both groups had similar rates of early postoperative complications: myocardial infarction (1.4%, n = 2 vs 0%, n = 0, P = 0.2), neurologic complications (1.4%, n = 2 vs 0%, n = 0, P = 0.2), reoperation for bleeding (0.7%, n = 1 vs 3%, n = 3, P = 0.2), intensive care unit length of stay (1 interquartile range, 1-1 days vs 1 interquartile range, 1-1 days, P = 0.7). Late survival (88% for simple vs 92% for complex, P = 0.4) was similar between groups. Cumulative incidence of late reoperation at 6 years is 0% for both groups (subdistribution hazard ratio = 1, P = 1). There was no difference in recurrent mitral regurgitation greater than 2+ at each year after surgery up to 6 years postoperatively. ConclusionMitral repair using an endoscopic, minimally invasive approach yields excellent mid-term outcomes regardless of disease complexity.

The Optimal Surgical Approach to Intradural Spinal Tumors: Laminectomy or Hemilaminectomy?

ObjectiveTraditionally, laminectomy has been the preferred surgical approach for the resection of intradural spinal tumors. Recent trends towards minimally invasive techniques have generated interest in hemilaminectomy as an effective alternative surgical approach to resect spinal tumors. However, it remains unclear if the potential benefits of hemilaminectomies, used in other routine spinal procedures, apply to intradural spinal tumors. This report presents a six-year single institutional analysis of open resection of intradural tumors using laminectomies as compared to hemilaminectomies.MethodsA single institution, multisurgeon, retrospective review of 52 patients undergoing resection of intradural spinal tumors over a six-year period was performed. Estimated blood loss, operative time, post-operative complications, length of stay, and post-operative clinical spinal instability were analyzed and compared between the two surgical techniques.ResultsThe mean follow-up was 34 and 20 months for the laminectomy and hemilaminectomy groups, respectively. There was no statistically significant difference in operative times between the two groups (hemilaminectomy: 250.13±76.44 minutes, laminectomy: 244.49±92.85 minutes; p=0.43). Similarly, there was no difference in overall estimated blood loss (hemilaminectomy: 125±74 cc, laminectomy: 256.05±320.8 cc; p=0.27) or mean hospital length of stay (hemilaminectomy: 4.00±2.12 days, laminectomy: 5.26±3.0 days; p=0.60). No patient in either surgical group had post-operative evidence of clinical spinal instability.ConclusionHemilaminectomy is a viable approach for the resection of intradural spinal tumors, with similar rates of post-operative complications to laminectomy when using an open surgical approach. The laminectomy allows for bilateral exposure of the entire spinal canal and neural foramina; and continues to be the preferred method for resection of large tumors with complex morphology.

Accuracy and complication rates of external ventricular drain placement with twist drill and bolt system versus standard trephine and tunnelation: a retrospective population-based study

BackgroundAn external ventricular drain (EVD) is typically indicated in the presence of hydrocephalus and increased intracranial pressure (ICP). Procedural challenges have prompted the development of different methods to improve accuracy, safety, and logistics.ObjectivesEVD placement and complications rates were compared using two surgical techniques; the standard method (using a 14-mm trephine burrhole with the EVD tunnelated through the skin) was compared to a less invasive method (EVD placed through a 2.7–3.3-mm twist drill burrhole and fixed to the bone with a bolt system).MethodsRetrospective observational study in a single-centre setting between 2008 and 2018. EVD placement was assessed using the Kakarla scoring system. We registered postoperative complications, surgery duration and number of attempts to place the EVD.ResultsTwo hundred seventy-two patients received an EVD (61 bolt EVDs, 211 standard EVDs) in the study period. Significant differences between the bolt system and the standard method were observed in terms of revision surgeries (8.2% vs. 21.5%, p = 0.020), surgery duration (mean 16.5 vs. 28.8 min, 95% CI 7.64, 16.8, p < 0.001) and number of attempts to successfully place the first EVD (mean 1.72 ± 1.2 vs. 1.32 ± 0.8, p = 0.017). There were no differences in accuracy of placement or complication rates.ConclusionsThe two methods show similar accuracy and postoperative complication rates. Observed differences in both need for revisions and surgery duration favoured the bolt group. Slightly, more attempts were needed to place the initial EVD in the bolt group, perhaps reflecting lower flexibility for angle correction with a twist drill approach.

Prehabilitation Programs Improve Exercise Capacity Before and After Surgery in Gastrointestinal Cancer Surgery Patients: A Meta-Analysis

IntroductionPrehabilitation programs or interventions are employed prior to surgery with the aim to optimize the patient before surgery and to improve their physiologic ability to recover from surgery. Components of these programs often include exercise, nutritional supplementation, and psychological interventions. This meta-analysis examines the impact of prehabilitation programs on both surgical and patient outcomes among gastrointestinal (GI) cancer patients undergoing surgery. MethodsA comprehensive literature search was conducted to identify all published randomized control trials (RCT) evaluating the use of prehabilitation programs (with one or more interventions) in GI cancer surgery patients. Outcomes assessed were 6-min walk distance (6MWD), postoperative complications, major complications (as defined as Clavien Dindo grade ≥ 3), surgical site infections (SSI), pneumonia, length of stay (LOS), 30-day readmission, and mortality. ResultsEleven RCTs including 929 patients (475 prehabilitation program and 454 controls) were analyzed. Prehabilitation programs were associated with statistically significant improvements in 6MWD between baseline and immediately prior to surgery (MD = 32.542 m; 95% CI, 10.774–54.310; p = 0.003) and 4–8 weeks after surgery (MD = 48.220 m; 95% CI, 1.532–94.908; p = 0.043) compared with patients who did not receive prehabilitation programs. Similar rates of postoperative complications, major complications, SSI, pneumonia, 30-day readmission, and mortality, as well as LOS, were observed (p > 0.05). ConclusionsPrehabilitation programs improve exercise capacity both before and after surgery, with no significant difference in LOS, or rates of postoperative complications, 30-day readmission, and mortality. Future studies assessing the different components of prehabilitation programs to identify the most beneficial interventions are required.

Oxidized regenerated cellulose for a clear thoracoscopic view: a single-centre randomized trial.

During video-assisted thoracoscopic surgery (VATS), blood oozing from the surface of the access port wound can hamper the surgical view. Although this oozing is difficult to prevent, it can be decreased by placing a wound edge protector with oxidized regenerated cellulose (ORC) on the surface of the access port wound, thereby improving the surgical outcomes and safety of VATS. We conducted a prospective, single-centre, open-label, randomized clinical trial to evaluate the operative outcomes of VATS when using the ORC (ORC group) compared with operative outcomes without using the ORC (non-ORC group). The primary end point was interruption of the operation as a result of blood oozing from the surface of the access port wound. The secondary end points were the other intraoperative and postoperative outcomes. A total of 108 patients were divided into the ORC group (n = 54) and the non-ORC group (n = 54). Compared with the non-ORC group, the ORC group had fewer patients with an interruption in the operation (11.1% vs 51.8%; P < 0.001), less need for wound haemostasis of the access ports during wound closure (44.4% vs 72.2%; P = 0.003), similar rates of postoperative deaths and complications and a tendency for shorter operation times (149.3 vs 168.8 min, respectively; P = 0.083). The use of an ORC sheet around a wound edge protector for haemostasis can ensure a clear view during VATS. UMIN000031112.

In Degenerative Spondylolisthesis, Unilateral Laminotomy for Bilateral Decompression Leads to Less Reoperations at 5 Years When Compared to Posterior Decompression With Instrumented Fusion: A Propensity-matched Retrospective Analysis.

Multicenter retrospective cohort study. The aim of this study was to compare reoperation rates at 5-year follow-up of unilateral laminotomy for bilateral decompression (ULBD) versus posterior decompression with instrumented fusion (Fusion) for patients with low-grade degenerative spondylolisthesis (DS) with lumbar spinal stenosis (LSS) in a multicenter database. Controversy exists regarding whether fusion should be used to augment decompression surgery in patients with LSS with DS. For years, the standard has been fusion with standard laminectomy to prevent postoperative instability. However, this strategy is not supported by Level 1 evidence. Instability and reoperations may be reduced or prevented using less invasive decompression techniques. We identified 164 patients with DS and LSS who underwent ULBD between January 2007 and December 2011 in a multicenter database. These patients were propensity score-matched on age, sex, race, and smoking status with patients who underwent Fusion (n = 437). Each patient required a minimum of 5-year follow-up. The primary outcome was 5-year reoperation. Secondary outcome measures included postoperative complication rates, blood loss during surgery, and length of stay. Logistic regression models were used to estimate the odds ratio of the 5-year reoperation rate between the two surgical groups. The reoperation rate at 5-year follow-up was 10.4% in the ULBD group and 17.2% in the Fusion group. ULBD reoperations were more frequent at the index surgical level; Fusion reoperations were more common at an adjacent level. The two types of operations had similar postoperative complication rates, and both groups tended to have fusion reoperations. For patients with stable DS and LSS, ULBD is a viable, durable option compared to fusion with decreased blood loss and length stay, as well as a lower reoperation rate at 5-year follow-up. Further prospective studies are required to determine the optimal clinical scenario for ULBD in the setting of DS. 3.
