Open Pancreaticoduodenectomy

Several studies have compared laparoscopic pancreaticoduodenectomy (LPD) and open pancreaticoduodenectomy (OPD) in patients with periampullary carcinoma; however, only a few studies have made such a comparison on patients with ampulla of Vater cancer (AVC). We compared the perioperative and oncologic outcomes between LPD and OPD in patients with AVC using propensity-score-matched analysis. A total of 359 patients underwent PD due to AVC during the study period (76 LPD, 283 OPD). After propensity score matching, the LPD group showed significantly longer operation time than did the OPD group (400.2 vs. 344.6 min, p < 0.001). Nevertheless, the LPD group had fewer painkiller administrations (8.3 vs. 11.1, p < 0.049), fewer Grade II or more severe postoperative complications (15.9% vs. 34.8%, p = 0.012), and shorter postoperative hospital stays (13.7 vs. 17.3 days, p = 0.048), compared with the OPD group. There was no significant difference in recurrence-free outcomes and overall survival between the two groups (p = 0.754 and 0.768, respectively). Compared with OPD, LPD for AVC had comparative oncologic outcomes with less pain, less postoperative morbidity, and shorter hospital stays. LPD may serve as a promising alternative to OPD in patients with AVC.

Abstract Introduction Treatment guidelines for hepatoblastoma discourage nonanatomic liver resections. However, the evidence for this is inadequate and comes from a study performed almost two decades ago which additionally contained inherent limitations. This study aimed to assess the feasibility and oncologic outcomes of nonanatomic resections (NAR) performed in diligently selected patients and compare the results with anatomic resections (AR). Materials and Methods A total of 120 patients who underwent liver resections for hepatoblastoma between January 2008 and July 2019 were reviewed. Feasibility of NAR was based on postchemotherapy relations to vessels, site of the lesion, and possibility of achieving negative resection margins. Results AR was performed in 95 patients and 25 had NAR. The NAR cohort had similar International Childhood Liver Tumors Strategy Group (SIOPEL) risk group distribution. Blood loss and operative times were lower in patients undergoing NAR. No differences were noted between the two groups concerning postoperative morbidity and hospitalization. There were no pathologic positive margins or local recurrences in the NAR patients. Relapse free (RFS) and overall survival (OS) was similar in the two groups (p = 0.54 and 0.96, respectively). Subgroup analysis of only posttreatment extent of tumor (POSTTEXT) I and II patients also showed no difference in RFS or OS for the two groups with a persistent significant difference in operative times and blood loss. Conclusion NAR is feasible with clear margins in carefully selected patients. It is not associated with more complications and outcomes are not inferior to AR. NAR is associated with lesser blood loss and operative time.

Abstract Background Liver resection (LR) and enucleation (EN) are the main surgical treatment for giant hepatic hemangioma (HH), but how to choose the type of surgery is still controversial. This study aimed to explore the efficacy and the factors affecting the choice of open procedure for HH. Methods The data for patients with pathologically confirmed HH who underwent open surgery from April 2014 to August 2020 were analyzed retrospectively. Univariate and multivariate analyses with logistic regression were performed to disclose the factors associated with the choice of EN or LR. Propensity score matching (PSM) analysis was used to compare the efficacy of the two procedures. Results A total of 163 and 110 patients were enrolled in the EN and LR groups. Following 1:1 matching by PSM analysis, 66 patients were selected from each group. Centrally located lesions (OR: 0.131, 95% CI 0.070–0.244), tumors size > 12.1 cm (OR: 0.226, 95% CI 0.116–0.439) and multiple tumors (OR: 1.860, 95% CI 1.003–3.449) were independent factors affecting the choice of EN. There was no significant difference in the median operation time (156 vs. 195 min, P = 0.156), median blood loss (200 vs. 220 ml, P = 0.423), blood transfusion rate (33.3% vs. 33.3%, P = 1.000), mean postoperative feeding (3.1 vs. 3.3 d, P = 0.460), mean postoperative hospital stay (9.5 vs. 9.0 d, P = 0.206), or the major complication rates between the two groups. Conclusions Peripherally located lesions, tumors size ≤ 12.1 cm and multiple tumors were more inclined to receive EN. There was no significant difference in the efficacy of EN or LR.

40 Background: The number of the oldest-old patients with gastric cancer has been increasing in Japan. Selecting optimal operation for these patients is difficult because coping with both radicality and tolerability of surgery is mandatory. The aim of this study is to clarify the feasibility and effectiveness of gastrectomy for these patients. Methods: A total of 721 old patients (aged 75 years old and older) with gastric cancer who underwent curative gastrectomy at Shizuoka Cancer Center between from Oct. 2002 to Aug. 2015 were included in this study. The patients were classified into oldest-old group (OOP; aged 85 years and older) and old group (OP; aged 75 to 84 years old). Characteristics of the patients and short and long-term outcomes were compared between the groups. Results: OOP group included 57 patients, and OP group 664 patients. Though median serum albumin level in OOP group (3.8 g/dl) was significantly lower than in OP group (4.1 g/dl) (p = 0.002), the other clinicopathological characteristics including gender, BMI, co-morbidity, ASA-PS, ECOG-PS and preoperative stage were not significantly different between the groups. In terms of operative results, gastrectomy with reduced extent of lymph node dissection was frequently performed in OOP group (33.3%) than in OP group (6.0%) with significant difference (p < 0.001). Median operation time was significantly shorter in OOP group (195 minutes) than in OP group (222 minutes) (p = 0.001), and median blood loss was significantly less in OOP group (154 ml) than in OP group (227 ml) (p = 0.041). There was no significant difference of the incidence of postoperative complications between the groups. There was no significant difference of overall survival (p = 0.973) and disease-specific-survival (p = 0.549) between the groups. In multivariate analysis, preoperative BMI < 20, serum albumin < 3.8 g/dl and 15 days or more postoperative hospital stay were revealed as significant independent prognostic factors. Conclusions: Gastrectomy is safe with acceptable oncologic outcomes for OOP with optimally reducing the extent of surgery in each patient. In order to improve the outcome in OOP, preoperative nutritional management and support for home health care system should be considered.

Abstract Background Endoscopic resection (ER) might affect subsequent laparoscopic gastrectomy (LG) because of the electrical coagulation, but the effect remains controversial. The purpose of this meta-analysis was to analyze the effect of ER on the short-term surgical outcomes of subsequent LG. Materials and methods The PubMed, EMBASE, and Cochrane Library databases were searched to find eligible studies published from inception to March 21, 2021. Short-term surgical outcomes were compared between the ER-LG group and the LG-only group. The registration ID of this current meta-analysis on PROSPERO is CRD42021238031. Results Nine studies involving 3611 patients were included in this meta-analysis. The LG-only group had a higher T stage (T1-T2: OR=2.42, 95% CI=1.09 to 5.34, P=0.03; T3-T4: OR=0.41, 95% CI=0.19 to 0.91, P=0.03) than the ER-LG group. The ER-LG group showed a shorter operation time than the LG-only group (MD=−5.98, 95% CI=−10.99 to −0.97, P=0.02). However, no difference was found in operation time after subgroup analysis of propensity score matching studies. No significant difference was found in intraoperative blood loss, time to first oral feeding, or postoperative hospital stay between the ER-LG group and the LG-only group. And no significance was found in overall complications (OR=1.16, 95% CI=0.89 to 1.50, P=0.27), complications of grade ≥ II (OR=1.11, 95% CI=0.71 to 1.73, P=0.64), complications of grade ≥ III b (OR=1.47, 95% CI=0.49 to 4.43, P=0.49) between the ER-LG group and the LG-only group. Conclusions ER did not affect subsequent LG in terms of short-term outcomes, and the ER-LG group might have a shorter operation time than the LG-only group.

Abstract Background: A large number of patients suffer recurrence after curative resection, and mortality from colon cancer remains high. The role of cancer-associated malnutrition such as the neutrophil-to-lymphocyte ratio (NLR) in cancer recurrence and death has been increasingly recognized. This study aimed to analyze long-term oncologic outcomes of Stage II-III colon cancer to examine the prognostic value of NLR using a propensity score analysis.Methods: A total of 442 patients with colon cancer underwent radical surgery between 2000 and 2014 at Tokyo Medical University Hospital. Long-term oncologic outcomes of these patients were evaluated according to NLR values. A cut-off NLR of 3.0 was used based on receiver operating characteristic curve analysis. A propensity score analysis according to tumor sidedness was also performed. Primary outcomes were overall survival (OS) and relapse-free survival (RFS). Results: Patients with lower NLR values (“lower NLR group”) were more likely to have lymph node metastasis compared to those with higher NLR values (“higher NLR group”) before case matching. After case matching, clinical outcomes were similar between the two groups. There were no significant difference in 5-year OS and 5-year RFS rates between the two groups before case matching based on propensity scores. After case matching, 5-year OS rates were 94.5% in the lower NLR group (n = 135) and 87.0% in the higher NLR group (n = 135), showing a significant difference (p = 0.042). Five-year RFS rates were 87.8% in the lower NLR group and 77.9% in the higher NLR group, also showing a significant difference (p = 0.032). Among patients with left-sided colon cancer, 5-year OS and 5-year RFS rates were 95.2% and 87.3% in the lower NLR group (n = 88), respectively, and 86.4% and 79.2% in the higher NLR group (n = 71), respectively, showing significant differences (p = 0.014 and p = 0.047, respectively).Conclusions: The NLR is an important prognostic factor for advanced colon cancer, especially for left-sided colon cancer.

Abstract Objective To compare perioperative and oncologic outcomes of open modified ureterosigmoidostomy urinary diversion (OMUUD) and intracorporeal modified ureterosigmoidostomy urinary diversion (IMUUD) following laparoscopic radical cystectomy (LRC). Patients and methods We retrospectively reviewed our single institutional collected database patients undergoing LRC from October 2011 to October 2019. The perioperative characteristics were compared between OMUUD and IMUUD, and overall survival (OS) and progression-free survival (PFS) were evaluated by the Kaplan-Meier method. Results Overall, 84 patients were included. OMUUD and IMUUD were performed in 63 (75%) and 21 (25%) patients, respectively. IMUUD patients demonstrated shorter postoperative length of stay (16.24 ± 3.91 days vs. 18.98 ± 7.41 days, P = 0.033), similar operation time (498.57 ± 121.44 vs. 462.24 ± 99.71, P = 0.175), similar estimated blood loss [400 (200–475) ml vs. 400 (200–700) ml, P = 0.095], and similar overall complication rate within 30 days (19.05% vs. 25.40%, P = 0.848) and 90 days (23.81% vs. 17.46%, P = 0.748). Complete urinary control rate was 87.3% (55/63) in the OMUUD group. In IMUUD, the complete urinary control rate was 90.5% (19/21). There was no significant difference in OS (χ2 = 0.015, P = 0.901) and PFS (χ2 = 0.107, P = 0.743) between the two groups. Conclusion IMUUD postoperative recovery is faster; other perioperative outcomes and oncology results are not significantly different with OMUUD. It is indicated that IMUUD can be utilized safely and effectively in the urinary diversion after LRC.

Summary Currently, the reports on esophageal endoscopic submucosal dissection (ESD) assisted by traction with a snare are rare. Because a snare is a commonly used endoscopic accessory and is easily available, its application in mucosal traction is worth exploring. The present study aims to evaluate the safety and effectiveness of snare-endoclip traction-assisted ESD for esophageal intraepithelial neoplasia. Cases of esophageal intraepithelial neoplasia resected using ESD in the Digestive Endoscopy Center of Guangzhou Nanfang Hospital, China from June 2013 to March 2019 were retrospectively analyzed. The procedure of snare-endoclip traction-assisted ESD was compared with nontraction-assisted ESD by using a propensity score matching analysis. Operation time, en bloc and R0 resection, intra- and postoperative complications, and surgery-related costs were mainly evaluated. Overall, 99 cases of esophageal intraepithelial neoplasia under tissue biopsy were included in the present study. Further, 22 exact matched pairs were obtained. There were no differences in en bloc and R0 resection rates, intra- and postoperative complications, and costs of disposable surgical accessories between the traction group and the nontraction group. However, median operation time showed a significant difference: traction group, 50.0 min (range, 20–100 min); nontraction group, 70.0 min (range, 35–133 min), P=0.012. In conclusion, snare-endoclip traction-assisted ESD for esophageal intraepithelial neoplasia was safe and shortened operation time in the study, thereby improving the efficiency of ESD. Despite the additional use of a snare and endoclips for traction, the total costs of endoscopic accessories seemed not to be increased.

The Impact

Background Oncologic outcomes for colon cancer are optimal when chemotherapy is started within 6 to 8 weeks after surgery. The study objective was to investigate the impact of operative modality and urgency on the time interval from surgery to adjuvant chemotherapy. Methods This is a retrospective institutional tumor registry cohort study of open and laparoscopic/robotic colorectal resections for stage II-IV cancer between April 2010 and January 2018. Primary outcome was time from surgery to chemotherapy. Predictor variables were adjusted for imbalances by propensity score weighting. Results A total of 220 patients met inclusion criteria: 171 elective (108 laparoscopic/robotic and 63 open) and 49 urgent colectomies. After propensity score weighting, there was no significant difference in time to chemotherapy between elective minimally invasive and open surgical approaches (48 days vs. 58 days, P = .187). Only 68.9% of minimally invasive and 50.8% of open colectomy patients started chemotherapy within 8 weeks of surgery. There was a significant difference ( P = .037) among surgical sites with rectal resections having the longest (55 days), and right colectomies having the shortest (46 days), time to chemotherapy. Patients who had urgent operations had significantly longer hospital length of stay ( P < .001) and higher post-discharge emergency department visit rates ( P < .001) than the elective operation group. However, there was no significant difference in time to chemotherapy. Discussion Neither operative modality nor operative urgency resulted in a significant difference in postoperative time to initiating chemotherapy. Future efforts should be focused on identifying postoperative recovery criteria and optimum multidisciplinary communication methods that allow recovered patients to start chemotherapy sooner.
