Facility Volume Thresholds for Optimization of Short- and Long-Term Outcomes in Patients Undergoing Hepatectomy for Primary Liver Tumors. J Gastrointest Surg 2023; 27:273-282. [PMID: 36443556 DOI: 10.1007/s11605-022-05541-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2022] [Accepted: 11/13/2022] [Indexed: 11/30/2022]
Abstract
BACKGROUND Volume-outcome relationships have been described for a variety of surgical procedures. We aimed to define the facility volume threshold at which postoperative mortality after hepatectomy was optimal. METHODS We determined volume percentiles for institutions performing hepatectomy for any primary liver tumor within the National Cancer Database (2004-2017). Marginal structural logistic regression defined the volume percentile (Vmin) at which the odds of 90-day mortality were optimally reduced in patients with hepatocellular carcinoma (HCC) or intrahepatic cholangiocarcinoma (ICC). Short-term postoperative and survival outcomes were compared between patients treated at facilities above and below Vmin. RESULTS Thresholds for the 10th/25th/50th/75th/90th percentiles were 2/7/26/46/59 hepatectomies/year. A total of 17,833 patients underwent resection of HCC or ICC. The 90-day postoperative mortality was optimized at the 75th percentile for all hepatectomies (IP-weighted OR = 0.67, 95% CI = 0.52-0.87) and major hepatectomy (IP-weighted OR = 0.62, 95% CI = 0.49-0.80). Seven of 446 facilities met the Vmin threshold. The odds of 30-day mortality were also reduced for all hepatectomies (IP-weighted OR = 0.55, 95% CI = 0.42-0.73) and major hepatectomy (IP-weighted OR = 0.58, 95% CI = 0.41-0.75). There were no differences in length of stay or 30-day readmission rate. Patients with HCC or ICC treated at facilities ≥ 10th percentile had an associated improvement in overall survival. CONCLUSIONS Resection of HCC and ICC is performed at a large number of facilities. Postoperative mortality is optimally reduced at facilities performing at least 46 liver operations annually. Regionalization of surgical care among patients with primary liver malignancies to high-volume centers may result in improved outcomes.

Validation of the ISGLS classification of bile leakage after pancreatic surgery: A rare but severe complication. Eur J Surg Oncol 2022; 48:2440-2447. [PMID: 35842371 DOI: 10.1016/j.ejso.2022.06.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2022] [Revised: 06/17/2022] [Accepted: 06/20/2022] [Indexed: 12/14/2022] Open
Abstract
INTRODUCTION Hepaticoenterostomy is an important step of reconstruction during hepatopancreatobiliary (HPB) surgery with a subsequent bile leakage rate of up to 5%. The International Study Group of Liver Surgery (ISGLS) proposed a severity grading system for defining bile leakage after HPB surgery, which has not been validated after pancreatic surgery in a large patient cohort. The present study aimed to validate the ISGLS definition for bile leakage in pancreatic surgery and to investigate the postoperative outcomes of bile leakage after pancreatic resections. MATERIALS AND METHODS Data from the prospectively maintained database for pancreas surgery were extracted for any type of pancreatectomy with hepaticoenterostomy between 2006 and 2019. The severity of bile leakage was graded according to the ISGLS definition. The influence of our standardized hepaticoenterostomy technique and of the complexity of the surgical procedure on the rate of clinically relevant bile leakages (B and C) were assessed in three different timeframes. RESULTS Bile leakage was detected in 152 of 5,300 patients (2.9%). Clinically relevant bile leakages included seventy patients with grade B and eighty-two patients with grade C bile leakages (46.1% and 53.9%, respectively). During the study period, the overall rate of bile leakage showed to be stable (from 3.5% to 2.4%). Patients with grade C bile leakage had a higher rate of postoperative wound infection (P < 0.001) and longer ICU stays and hospital stays compared to patients with grade B bile leakage (P = 0.03 and P < 0.001 respectively). These parameters were significantly higher in patients with late grade C bile leakage but were similar between patients with grade B bile leakage and early grade C bile leakage (<5th day POD). In the whole patients' cohort, the 90-day mortality rate was 3.2% (174/5,300), with a rate of 25% in patients with bile leakage (38/152). CONCLUSION The ISGLS classification is a valid method for classifying postoperative bile leak after pancreas surgery. Standardization of our hepaticoenterostomy technique resulted in a stable rate of bile leakage. Although rare, bile leakage following pancreas surgery is a severe complication that has a major impact on patient outcomes and contributes significantly to morbidity and mortality, even in the absence of POPF.

Bile leak incidence, risk factors and associated outcomes in patients undergoing hepatectomy: a contemporary NSQIP propensity matched analysis. Surg Endosc 2022; 36:5710-5723. [PMID: 35467144 DOI: 10.1007/s00464-021-08938-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Accepted: 12/06/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND Despite advances in surgical technique, bile leak remains a common complication following hepatectomy. We sought to identify incidence of, risk factors for, and outcomes associated with biliary leak. STUDY DESIGN This is an ACS-NSQIP study. Distribution of bile leak stratified by surgical approach and hepatectomy type were identified. Univariate and multivariate factors associated with bile leak and outcomes were evaluated. RESULTS Robotic hepatectomy was associated with less bile leak (5.4% vs. 11.4%; p < 0.001) compared to open. There were no significant differences in bile leak between robotic and laparoscopic hepatectomy (5.4% vs. 5.3%; p = 0.905, respectively). Operative factors risk factors for bile leak in patients undergoing robotic hepatectomy included right hepatectomy [OR 4.42 (95% CI 1.74-11.20); p = 0.002], conversion [OR 4.40 (95% CI 1.39-11.72); p = 0.010], pringle maneuver [OR 3.19 (95% CI 1.03-9.88); p = 0.044], and drain placement [OR 28.25 (95% CI 8.34-95.72); p < 0.001]. Bile leak was associated with increased reoperation (8.7% vs 1.7%, p < 0.001), 30-day readmission (26.6% vs 6.8%, p < 0.001), 30-day mortality (2% vs 0.9%, p < 0.001), and complications (67.2% vs 23.4%, p < 0.001) for patients undergoing MIS hepatectomy. CONCLUSION While MIS confers less risk for bile leak than open hepatectomy, risk factors for bile leak in patients undergoing MIS hepatectomy were identified. Bile leaks were associated with multiple additional complications, and the robotic approach had an equal risk for bile leak than laparoscopic in this time period.

Abstract
BACKGROUND Laparoscopic and robotic minimally invasive liver surgery (MILS) is gaining popularity. Recent data and views on the implementation of laparoscopic and robotic MILS throughout Europe are lacking. METHODS An anonymous survey consisting of 46 questions was sent to all members of the European-African Hepato-Pancreato-Biliary Association. RESULTS The survey was completed by 120 surgeons from 103 centers in 24 countries. Median annual center volume of liver resection was 100 [IQR 50-140]. The median annual volume of MILS per center was 30 [IQR 16-40]. For minor resections, laparoscopic MILS was used by 80 (67%) surgeons and robotic MILS by 35 (29%) surgeons. For major resections, laparoscopic MILS was used by 74 (62%) surgeons and robotic MILS by 33 (28%) surgeons. The majority of the surgeons stated that minimum annual volume of MILS per center should be around 21-30 procedures/year. Of the surgeons performing robotic surgery, 28 (70%) felt they missed specific equipment, such as a robotic-CUSA. Seventy (66%) surgeons provided a formal MILS training to residents and fellows. In 5 years' time, 106 (88%) surgeons felt that MILS would have superior value as compared to open liver surgery. CONCLUSION In the participating European liver centers, MILS comprised about one third of all liver resections and is expected to increase further. Laparoscopic MILS is still twice as common as robotic MILS. Development of specific instruments for robotic liver parenchymal transection might further increase its adoption.

Abstract
INTRODUCTION Laparoscopic gastrectomy (LG) is a complicated procedure with a long learning curve. This study was performed to investigate the usefulness of our stepwise training program for LG for improving the quality of the surgery. METHODS The stepwise training method comprised the following four steps: (1) basic training using a dry box and checking by mentors; (2) advanced training, including the use of animals and cadavers; (3) clinical experience, including standardization and preoperative three-dimensional simulation; and (4) self-assessment and feedback. In total, 153 patients who underwent curative gastrectomy for gastric cancer were included in this study. RESULTS The operative time gradually decreased for both laparoscopic distal gastrectomy (LDG) (2013, 395 minutes; 2017, 278 minutes; P < .001; ρ = -0.68) and laparoscopic total gastrectomy (LTG) (2013, 476 minutes; 2017, 319 minutes; P < .001; ρ = -0.56). The blood loss volume gradually decreased for both LDG (2013, 43.0 mL; 2017, 18.6 mL; P < .005; ρ = -0.30) and LTG (2013, 143.8 mL; 2017, 13.5 mL; P < .005; ρ = -0.41). CONCLUSIONS Our stepwise training program contributes to reduce operation time and blood loss in LG.

Abstract
INTRODUCTION Laparoscopy is becoming the standard approach in liver surgery. As the degree of difficulty varies greatly from core skills to advanced procedures, strategies for teaching young surgeons need to be reconsidered. We here aimed to design a skills curriculum for LLR. METHODS Using the nominal group technique, 22 substeps of LLR were identified by 61 hepatobiliary surgeons. The raters were asked to rate (1) the difficulty of substeps and (2) the minimum number of times that the substep must be performed for mastery of the technique. According to the frequency of defined substeps, being estimated on the basis of high volume center experiences (n = 222 LLR; 1/2017-12/2018), the center's training capacity and defined goals for a 2-year fellowship were calculated. RESULTS Ten surgical substeps (45%) are routinely performed and can thus be taught sufficiently at centers carrying out ≥50 LLR in 2 years. As the mobilization of the right liver lobe and the dissection of the hepatic artery or portal vein is performed in only 27% and 28% of all LLR, respectively, sufficient training can only be provided at centers with ≥100 LLRs in 2 years. Mastery of complex parenchymal dissection (19%) and hilar lymphadenectomy (8%) can only be achieved in center performing ≥200 LLR in 2 years. CONCLUSION We here suggest a stepwise approach for training of hepatobiliary fellows in LLR. Based on the estimated complexity of the substeps and the size of the center, not every substep can be learned within 2 years.

Is It Time to Consider Laparoscopic Hepatectomy for Intrahepatic Cholangiocarcinoma? A Meta-Analysis. J Gastrointest Surg 2020; 24:2244-2250.

Abstract
OBJECTIVES The role of laparoscopic hepatectomy (LH) for intrahepatic cholangiocarcinoma (ICC) remains indefinite, though the utilization of this minimally invasive approach has been increasing for ICC. We herein performed a meta-analysis to investigate this issue. METHODS Six retrospective studies including 384 patients who had undergone LH and 2147 patients who had undergone open hepatectomy (OH) for ICC were included. The fixed-effects or random-effects models were utilized for data analysis. RESULTS Compared with patients who had undergone OH for ICC, patients who had undergone LH for ICC experienced more R0 resections (81.6 versus 73.8%, risk ratio (RR) = 1.08, 95% confidence interval (CI) 1.02-1.14; P = 0.008) but less major hepatectomies (37.7 versus 54.2%, RR = 0.69, 95% CI 0.60-0.79; P < 0.0001), less lymph node dissections (38.0 versus 61.5%, RR = 0.62, 95% CI 0.54-0.70; P < 0.0001), and smaller tumor size resected (4.14 versus 4.94 cm, weighted mean difference = - 0.80 cm, 95% CI - 1.38 to - 0.22 cm; P = 0.007). No significant difference was observed in other perioperative results (all P > 0.05) or overall survival (hazard ratio (HR) = 1.38, 95% CI 0.63-3.02; P = 0.43). CONCLUSIONS LH has comparable safety, feasibility, and oncological efficacy to that of OH for ICC and has superiority in R0 resection over OH. It may be time to consider LH for ICC only if a more thorough effort on lymph node dissection is undertaken in selective patients at experienced centers.

Abstract
BACKGROUND Minimally invasive hepatectomy has well-known advantages over the traditional open approach. Inherent limitations of laparoscopy make major hepatectomies and the resection of upper and posterior segments a great technical challenge. The robotic approach overcomes most of these limitations, and this technology is most useful in the resection of the deeply located caudate lobe. METHODS We describe the robotic caudate lobe resection technical aspects, using the first robotic resection of the caudate lobe to treat a biphenotypic hepatocholangiocarcinoma to illustrate the procedure. We also performed a literature review on the current status of the robotic approach to segment (Sg) 1. RESULTS Technical approach to the robotic caudate lobe resection is described in a patient with uneventful post-operative recovery. Literature review demonstrated only four previous authors reporting the use of this technique. CONCLUSION We present a step-by-step approach to the hepatic Sg 1 resection by robotic approach.

Abstract
BACKGROUND Surgeon suturing technology plays a pivotal role in patient recovery after laparoscopic surgery. Intracorporal suturing and knot tying in minimally invasive surgery are particularly challenging and represent a key skill for advanced procedures. In this study, we compared the application of multidirectional stitching technology with application of the traditional method in a laparoscopic suturing instructional program. METHODS We selected forty residents within two years of graduation to assess the specialized teaching of laparoscopic suturing with laparoscopic simulators. The forty students were randomly divided into two groups, a control group and an experimental group, with twenty students in each group. The control group was scheduled to learn the traditional suture method, and the experimental group applied multidirectional stitching technology. The grades for suturing time, thread length, accuracy of needle entry, stability of the knot, tissue integrity, and tightness of the tissue before and after the training program were calculated. RESULTS There was no significant difference between the two groups before the learning intervention. After the program, both groups significantly improved in each subject. There were significant differences between the control group and the experimental group in suture time (P = 0.001), accuracy of needle entry and exit (P = 0.035), and whether the suture tissue had cracks (P = 0.030). However, the two groups showed non-significant differences in thread length (P = 0.093), stablity of the knot (P = 0.241), or tightness of the tissue (P = 0.367). CONCLUSIONS Multidirectional stitching technology improves the efficiency and effectiveness of traditional laparoscopic suture instructional programs. It might be a practicable, novel training method for acquiring proficiency in manual laparoscopic skills in a training setting.

Abstract
Neuroendocrine neoplasms of the pancreas (pNEN) have an increasing incidence and prevalence. Thus, this entity is of increasing clinical significance. Patients with pNEN become clinically apparent due to different and unspecific symptoms. Some tumours secrete hormones and peptides and become clinically symptomatic. In general, these tumours can metastasise early and even small tumours lead to distant metastases. Nonetheless, primary tumour size and grading are important prognostic factors. On the basis of a systematic literature research and the formulation of key issues according to the PICO system, therapeutic concepts were established. These concepts were evaluated with a Delphi process among the members of the pancreas research group and the indications for surgery group of the German Society of General and Visceral Surgery. Thus this article gives an overview of the surgical treatment modalities and indications for the treatment of pNEN. Surgery is still the gold standard in treatment and the only potential chance of cure. Surgery is indicated for sporadic as well as hereditary pNEN > 2 cm independent of the functional activity. A so called "wait and see" strategy might be indicated in smaller pNEN; however, there is little evidence for this approach. In this respect, pNEN of 1 - 2 cm represent a surgical indication. The treatment of hereditary pNEN is challenging and should be interdisciplinary. Even in the case of distant metastases, a curative approach might be feasible and multimodal treatment is indicated.

The Differences in the Characteristics of Insulin-producing Cells Using Human Adipose-tissue Derived Mesenchymal Stem Cells from Subcutaneous and Visceral Tissues. Sci Rep 2019; 9:13204. [PMID: 31519950 PMCID: PMC6744430 DOI: 10.1038/s41598-019-49701-0] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2019] [Accepted: 08/29/2019] [Indexed: 02/06/2023] Open
Abstract
The aim of this study was to investigate the characteristics of insulin producing cells (IPCs) differentiated from adipose-tissue derived stem cells (ADSCs) isolated from human subcutaneous and visceral adipose tissues and identify ADSCs suitable for differentiation into efficient and functional IPCs. Subcutaneous and visceral adipose tissues collected from four (4) patients who underwent digestive surgeries at The Tokushima University (000035546) were included in this study. The insulin secretion of the generated IPCs was investigated using surface markers by: fluorescence activated cell sorting (FACS) analysis; cytokine release; proliferation ability of ADSCs; in vitro (glucose-stimulated insulin secretion: (GSIS) test/in vivo (transplantation into streptozotocin-induced diabetic nude mice). The less fat-related inflammatory cytokines secretions were observed (P < 0.05), and the proliferation ability was higher in the subcutaneous ADSCs (P < 0.05). Insulin expression and GISI were higher in the subcutaneous IPCs (P < 0.01 and P < 0.05, respectively). The hyperglycaemic state of all mice that received IPCs from subcutaneous fat tissue converted into normo-glycaemia in thirty (30) days post-transplantation (4/4,100%). Transplanted IPCs were stained using anti-insulin and anti-human leukocyte antigen antibodies. The IPCs generated from the ADSCs freshly isolated from the human fat tissue had sufficient insulin secreting ability in vitro and in vivo.

Abstract
Objectives: To compare King Saud University Medical City experience in laparoscopic liver resection with our previously established database for open resections. Methods: A retrospective study was conducted at King Saud University Medical City, Riyadh, Saudi Arabia. All adult patients who underwent liver resection from 2006 to 2017 were included. Patients who had their procedure converted to open were excluded. Results: Among the 111 liver resections included, 22 (19.8%) were performed laparoscopically and 89 (80.1%) were performed using the open technique. Malignancy was the most common indication in both groups (78.5%). The mean operative time was 275 min (SD 92.2) in the laparoscopic group versus 315 min (SD 104.3) in the open group. Intraoperative blood transfusion was required in the laparoscopic (9%) and open groups (31.4%). The morbidity rate was 13.6% in the laparoscopic group and 31.4% in the open group, and the mortality rate was 0% in the laparoscopic group and 5.6% in the open group. Conclusion: Laparoscopic liver resection appears to be a safe technique and can be performed in various benign and malignant cases.
