Clinical Decision-Making by Gastroenterologists and Hepatologists for Patients with Early Hepatocellular Carcinoma

Background

Choice of therapy in early hepatocellular carcinoma (HCC) is controversial, and no broad consensus exists as to how patient and tumor characteristics should be used to guide choice of therapy. We have previously reported on decision making in early HCC by liver surgeons. In the present study, we quantified the impact of clinical factors on choice of therapy for early HCC by gastroenterologists and hepatologists.

Methods

Physicians who treat HCC were invited to complete a web-based survey including ten case scenarios that systematically varied across seven clinical factors. Choice of therapy—liver transplantation (LT), liver resection (LR), radiofrequency ablation or intra-arterial therapy—was analyzed using multinomial logistic regression models.

Results

Tumor number and size, type of resection required, biological Model for End-Stage Liver Disease (MELD) score, and platelet count had the largest effects on choice of therapy. For example, LR was more likely to be recommended over LT for patients with small solitary tumors versus multiple tumors [relative risk ratio (RRR) 3.63], those who would require a minor versus major LR (RRR 3.39), those with lower biological MELD score (6 vs. 10; RRR 1.95), and those with a higher platelet count (150,000/μL vs. 70,000/μL; RRR 2.77). In contrast, serum α-fetoprotein level and etiology of cirrhosis were not associated with choice of therapy. No physician-related factors studied had an impact on choice of therapy.

Conclusion

The clinical factors weighed most heavily by gastroenterologists and hepatologists are quite similar to those considered important by surgeons. There was good consensus among gastroenterologists and hepatologists as to the factors used to choose therapy.     

Intraoperative Ablation for Small HCC not Amenable for Percutaneous Radiofrequency Ablation in Child A Cirrhotic Patients

Background

Radiofrequency ablation (RFA) was initially started by radiologists as a percutaneous treatment, but surgeons started to use RFA by surgical approach for patients with tumors at locations difficult for the percutaneous procedure. The aim was to evaluate the results of intraoperative RFA for small hepatocellular carcinomas (HCCs) (<3 cm) in locations difficult for a percutaneous approach.

Methods

Two hundred forty-seven patients with small solitary HCC (<3 cm) were treated; 196 via percutaneous RFA while 51 patients presented at sites not amenable for percutaneous route. Twenty-seven out of 51 patients underwent surgical resection, while 24/51 patients underwent intraoperative RFA.

Results

The location and depth of the tumor from the liver capsule was the only significant factors in the choice of the surgeon between resection and RFA. RFA was successful in all tumors (complete ablation rate of 100 %). In the surgery group, all patients achieved R0 resection. Complication rate was comparable (p?=?1.0). After a median follow-up of 37 months (range, 10–45 months), no tumors showed neither local progression nor local recurrence and no significant difference was observed between two groups as regards early recurrence and number of de novo lesions (p?=?0.49). One-year and 3-year survival rates were 93 % and 81 %, respectively, in the resection group comparable to the corresponding rates of 92 % and 74 % in the RFA group (p?=?0.9).

Conclusion

For small HCC in locations difficult for a percutaneous approach, intraoperative RFA can be an alternative option for deep-seated tumors necessitating more than one segmentectomy achieving similar tumor control, and overall and disease-free survival.     

Single HCC in Cirrhotic Patients: Liver Resection or Liver Transplantation? Long-term Outcome According to an Intention-to-treat Basis

Background

Compensated cirrhotic patients with single hepatocellular carcinoma (HCC) ≤5 cm may benefit from both liver resection (LR) and liver transplantation (LT); however, the better 10-year actuarial survival of the two treatments remains unclear. We aimed to assess the long-term outcome of cirrhotic patients with single HCC ≤5 cm treated either with LR or LT on an intention-to-treat basis.

Methods

A total of 217 cirrhotic patients with single HCC ≤5 cm were evaluated at our department: 95 were treated with LR (LR group), and 122 were included on the waiting list for LT (LT group). Patients in the LR group were divided into very early HCC (tumor size ≤2 cm) and early HCC (tumor size >2 cm). Median follow-up was 5.3 (range 0.1–18) years.

Results

Tumor recurrence was 72 % in the LR group versus 16 % in the LT group (p < 0.001). 1-, 5-, and 10-year cumulative risk of recurrence was 18, 69, and 83 % in the LR group versus 4, 18, and 20 % in the LT group (p < 0.001). Ten-year actuarial survival was 33 % in the LR group versus 49 % in the LT group (p = 0.002). At HCC recurrence, 27.3 % were included on the waiting list for salvage transplantation (very early HCC group) versus 15.1 % (early HCC group) (p = 0.2). After salvage transplantation, HCC recurrence was 0 % (very early HCC group) versus 40 % (early HCC group) (p = 0.2). No significant differences were observed in 1-, 5-, and 10-year actuarial survival between the very early HCC group and the LT group (95, 55, and 50 % vs. 82, 62, and 50 %).

Conclusions

LR should be the treatment of choice for cirrhotic patients with very early HCC.     

Endoscopic versus Open Radiofrequency Ablation for Treatment of Small Hepatocellular Carcinoma

Background

Surgical radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) is associated with superior oncological outcome in comparison with percutaneous RFA. The present study aimed to retrospectively evaluate the relative perioperative safety and postoperative outcome of the laparoscopic or thoracoscopic approach versus the open approach to RFA for small HCC.

Methods

A retrospective analysis was performed in 55 consecutive patients who underwent open (n = 32) or laparoscopic/thoracoscopic (LTS) RFA (n = 23) for primary unresectable HCC between January 2005 and December 2010. Baseline characteristics, survival/recurrence rates, and complications after treatment were compared between the two groups.

Results

There was a trend showing that LTS RFA was performed for tumors located in the anterior segment (e.g., segments III, V, VIII). The LTS RFA group had a significantly lower intraoperative blood loss, shorter operative time, and shorter postoperative hospital stay, compared with the open RFA group. No major postoperative complications occurred in patients who underwent LTS RFA. No significant differences in overall survival, recurrence-free survival and local recurrence rates were observed between the two groups.

Conclusions

In consideration of operative invasiveness and postoperative recovery, LTS RFA is superior to the open approach in patients with small HCC. Moreover, the surgical outcome did not differ between the two approaches. Laparoscopic/thorascopic RFA can be considered to be a useful procedure for ablation therapy.     

γ-Glutamyltranspeptidase is a Prognostic Marker of Survival and Recurrence in Radiofrequency-Ablation Treatment of Hepatocellular Carcinoma

Purpose

Serum γ-glutamyltranspeptidase (GGT) level, which is often elevated in hepatocellular carcinoma (HCC), has now been found to be an oxidative stress marker which correlates with inflammation in the extracellular hepatic microenvironment. The aim of this study was to investigate the prognostic significance of GGT serum levels in patients undergoing radiofrequency ablation (RFA) therapy for the treatment of HCC.

Methods

This retrospective study included 254 patients with small liver cancer (tumor of ≤5 cm in diameter and nodule of ≤3 cm) who had been treated with RFA. Baseline serum GGT was examined before therapy, and overall survival (OS) and recurrence-free survival were evaluated by the Kaplan–Meier method. Univariate and multivariate analyses were used to analyze the significance of GGT and other serum markers as prognostic factors.

Results

After a median follow-up of 27 months, 51 patients had died and 123 had hepatic recurrence. After treatment with RFA, HCC patients with elevated GGT had a shorter OS versus those with normal GGT level (p = 0.001); they also had higher recurrence (p = 0.001). On multivariate analysis, albumin (p = 0.003), GGT (p = 0.035), and tumor size (p = 0.027) were independent risk factors for survival, and GGT (p = 0.010) and tumor size (p = 0.026) were significant risk factors for recurrence.

Conclusions

Serum GGT is a convenient prognostic biomarker related to OS and recurrence in HCC patients undergoing RFA treatment.     

Response to Therapy as a Criterion for Awarding Priority to Patients With Hepatocellular Carcinoma Awaiting Liver Transplantation

Background

How to prioritize patients with hepatocellular carcinoma (HCC) for liver transplantation (LT) remains controversial. This study was designed to assess the effectiveness of a policy for prioritizing HCC patients according to their response to pre-LT therapy.

Methods

The study period was from 2000 to 2008. Dropout criteria included macroscopic vascular invasion, metastases, and poorly differentiated grade at pre-LT biopsy. A specific treatment algorithm was adopted to treat HCC before LT, and the effect of treatment was evaluated 3 months after listing or after the diagnosis of HCC for patients diagnosed while already on the waiting list. Patients were divided into two groups: group 1, patients with disease that completely or partially responded to therapy; and group 2, patients with stable, progressive, or untreatable disease. Group 2 patients were prioritized for LT unless full restaging and repeat biopsy identified dropout criteria.

Results

At the 3-month visit, 62 HCC patients (42%) were assigned to group 2 and 85 (58%) to group 1. Eleven of 12 dropouts due to tumor progression came from group 2 (P < 0.01). Response to therapy was the sole predictor of dropout probability, independent of tumor stage (competing risk analysis). The 42 patients in group 2 who were transplanted had much the same 3-year post-LT survival rate as the 57 transplanted patients in group 1 (with survival rates of 82% and 83%, respectively; P > 0.05), but a slightly higher risk of post-LT HCC recurrence (13% and 2%, respectively; P = 0.04).

Conclusions

Response to therapy is a potentially effective tool for prioritizing HCC patients for LT.     

Liver Transplantation in Patients with Hepatitis B Virus-Related Hepatocellular Carcinoma: The Influence of Viral Characteristics on Clinical Outcome

Background

Hepatitis B virus (HBV) relapse and/or hepatocellular carcinoma (HCC) recurrence remains a major concern for patients who undergo liver transplantation (LT) because of HBV-related HCC. This study investigates the correlation between HBV relapse and HCC recurrence and it explores factors that affect patient outcomes after LT.

Methods

Between September 2002 and August 2009, 78 consecutive patients who underwent LT because of HBV-related HCC were enrolled in this study. Serum samples obtained before LT were assayed both for virological factors associated with HBV DNA and for genotypic characteristics of the virus. All patient clinicopathological features and virological factors were assessed further by univariate and multivariate analyses to determine prognostic factors.

Results

During a median follow-up period of 29.4 months, 13 (16.6 %) patients experienced HCC recurrence and 18 (23.1 %) patients experienced HBV relapse. HBV relapse exhibited a close association with HCC recurrence (p = 0.004) and led to unfavorable overall survival after LT. Multivariate analysis of prognostic factors showed that the basal core promoter (BCP) mutation independently predicted a shorter survival period free from HBV relapse (p = 0.036). Moreover, with the exception of unfavorable tumor characteristics, the BCP mutation was found to be an important prognostic factor that affected HCC recurrence after LT (p = 0.042).

Conclusions

In this study, the HBV–BCP mutation was identified as an important predictor of post-LT clinical outcomes in patients with HBV-related HCC. Therefore, we recommend that aggressive antiviral treatment may be considered for patients associated with this risk factor.     

Immediate Radical Therapy or Conservative Treatments When Meeting the Milan Criteria for Advanced HCC Patients After Successful TACE

Background and aims

Many advanced hepatocellular carcinoma (HCC) cases can be successfully downstaged into the Milan criteria; however, immediate radical therapy cannot be applied to all such patients for various reasons. Of the patients who are not eligible for immediate radical therapy, some accept repeated downstaging therapies and some undergo persistent observation. The aim of the present study was to compare long-term survival between these two groups of patients.

Patients and Methods

Between August 2003 and October 2008, 156 HCC patients successfully received downstaging therapy resulting in compliance with the Milan criteria. Of those, 98 cases accepted radical therapies, including liver transplantation (LT), resection, or radiofrequency ablation (RFA) (group 1), and 58 cases underwent repeated transcatheter arterial chemoembolization (TACE) or persistent observation (group 2). The baseline characteristics, demographic data, downstaging protocol, and information on long-term outcomes were collected and compared.

Results

No significant differences were observed in the patient demographic data, downstaging protocols, or tumor characteristics between the two groups. The 1-, 3-, and 5-year overall survival rates were 92.9, 82.7, and 78.6 %, respectively, in group 1, whereas these rates were 82.8, 65.5, and 48.3 %, respectively, in group 2 (P?=?0.046). Among the 58 patients in group 2, the 1-, 3-, and 5-year overall survival rates were 92.3, 65.4, and 46.2 %, respectively, in the repeated TACE group, and 81.3, 65.6, and 50 %, respectively, in the persistent observation group (P?=?0.783).

Conclusion

Immediate radical therapy should be the first choice for advanced HCC patients who undergo successful TACE, and repeated TACE is unnecessary.     

Impact of surgical training and surgeon’s experience on early outcome in kidney transplantation

Purpose

The purpose of this study was to assess the impact of surgical training and surgeon’s experience on surgical quality and early outcome parameters.

Methods

The outcomes of 184 deceased donor kidney transplant procedures were retrospectively reviewed. Intraoperative quality parameters, complication rates, and early outcome parameters were analyzed with respect to surgeon’s experience. Surgeons were grouped according to their level of experience: trainees (n?=?5), who were senior residents in their transplant rotation; low-experience surgeons (n?=?4), who had an individual caseload of at least 30 supervised procedures; medium-experience surgeons (n?=?5), who had an individual caseload of a minimum of 30 unsupervised (+30 supervised) procedures; and high-experience surgeons (n?=?2), who had an individual caseload of more than 200 procedures.

Results

Surgical training was offered in 20 % of all cases. Surgeons with a high experience in kidney transplantation had a significantly lower warm ischemic time (30 versus 35 min, p?=?0.01) and total operation time (135 versus 155 min, p?=?0.43) as compared to the other study groups. However, this did not translate into a better outcome after transplantation. The complication rate and early outcome parameters such as length of hospital stay, serum creatinine at discharge, and graft and patient survival at 3 months post TX did not show any significant difference between the groups.

Conclusion

We conclude that hands-on training of residents in kidney transplantation is feasible and surgical experience can be safely gained within a staged surgical training program.     

Medium-Sized (3.1–5.0 cm) Hepatocellular Carcinoma: Transarterial Chemoembolization Plus Radiofrequency Ablation Versus Radiofrequency Ablation Alone

Purpose

This study was designed to retrospectively compare the effectiveness of combined transarterial chemoembolization (TACE) plus radiofrequency ablation (RFA) with that of RFA alone in patients with medium-sized (3.1–5.0 cm) hepatocellular carcinoma (HCC).

Methods

From March 2000 to April 2010, 57 patients, each with a single medium-sized HCC, were treated with combined TACE and RFA, and 66 were treated with RFA alone.

Results

During follow-up (mean, 42.5 ± 33.2 months; range, 2.6–126.2 months), local tumor progression was observed in 40% of treated lesions in the combined treatment group and in 70% in the RFA-alone group. The 1-, 3-, 5-, and 7-year local tumor progression rates were significantly lower in the TACE + RFA group (9%, 40%, 55%, and 66%, respectively) than in the RFA-alone group (45%, 76%, 86%, and 89%, respectively; P < 0.001). Multivariate analysis showed that treatment allocation (odds ratio [OR], 1.78; P = 0.016) and Child-Pugh class (OR, 1.96; P = 0.008) were significant independent factors associated with patient survival. The rates of major complications were 0% for the combined treatment group and 3% for the RFA-alone group.

Conclusions

The combination of TACE and RFA is safe and provides better local tumor control than RFA alone for the treatment of patients with medium-sized HCC. Our multivariate analysis showed that RFA-alone treatment and Child-Pugh class B were poor independent factors for determining the patient survival period.     

Sorafenib treatment is save and may affect survival of recurrent hepatocellular carcinoma after liver transplantation

Introduction

Recurrent hepatocellular carcinoma (HCC) after liver transplantation (LT) is a rare but challenging condition. In most cases, the recurrent tumor is presented with extrahepatic spread. Therefore, systemic treatment with sorafenib has to be assessed. Because of a plethora of possible drug interactions, e.g., with immunosuppressant or anti-infective therapy, safety and feasibility of sorafenib treatment requires special attention.

Materials and methods

We retrospectively analyzed 18 patients who suffered from recurrent advanced HCC after LT between January 2002 and December 2010 at the University Hospital Heidelberg regarding safety of sorafenib treatment and survival.

Results

Results showed that 8 patients were eligible for treatment with sorafenib showing a median time to progression (TTP) of 4.5 months and an overall survival of 9 months. Most common side effects were grades I and II diarrhea and hand–foot syndrome (HFS) which could be managed by sorafenib dose reduction. No grade III or IV adverse events (AEs) were noticed. No patient had to discontinue treatment due to AEs. The ten patients not amenable for sorafenib treatment, due to initial poor performance status or its deterioration after first line treatment, were treated with surgical resection (n?=?3), locoregional therapies (n?=?1), or palliative radiation therapy (n?=?1). They showed a median overall survival of 2.3 months.

Conclusion

Sorafenib may represent a therapeutic option for recurrent HCC after LT with manageable side effects. The clinical benefit of sorafenib in this setting is promising but needs to be confirmed in a prospective randomized trial.     

Performance Status Enhances the Selection of Treatment for Patients with Hepatocellular Carcinoma Within the Milan Criteria

Background

Performance status (PS) is closely linked with survival in patients with hepatocellular carcinoma (HCC). We investigated its impact on treatment strategy for small HCC(s).

Methods

A total of 360 and 362 HCC patients within the Milan criteria undergoing surgical resection (SR) and radiofrequency ablation (RFA), respectively, were prospectively enrolled. Patients were classified into PS 0 (n = 558) and PS ≥1 (n = 164) groups. Propensity score analysis was performed, and 168 and 35 matched pairs were selected from patients with PS 0 and ≥1, respectively.

Results

The SR group was younger and had a higher male-to-female ratio, higher prevalence of hepatitis B, lower prevalence of hepatitis C, better PS, better liver functional reserve, and larger tumor burden than the RFA group (all p < 0.05). Among patients with PS 0, the SR group was consistently younger, less cirrhotic, and had larger tumor burden (all p < 0.05). The long-term survival was comparable between SR and RFA group in patients with PS 0. After propensity score matching, SR provided significantly better long-term survival than RFA for patients within the Milan criteria classified as PS 0 (p = 0.016); the Cox proportional hazards model showed consistent results. There was no significant difference of overall survival between the SR and RFA group in patients with PS ≥1 before or after propensity score matching (both p > 0.05).

Conclusions

For HCC patients within the Milan criteria and classified as PS 0, SR provides a better long-term survival compared with RFA. Performance status may enhance treatment selection and stratify the risk of survival in these patients.     

The laparoscopic approach for radiofrequency ablation of hepatocellular carcinoma—indication, technique and results

Background

The therapeutic regimen for patients suffering of HCC in liver cirrhosis must pay attention to the underlying liver disease. Surgical resection is often limited by liver function and transplantation, as an optimal therapy for many early diagnosed HCC, by the availability of organs. Due to three prospective, randomized trials radiofrequency ablation (RFA) is the standard method of local ablation. RFA compared with resection for HCC in liver cirrhosis yields similar results concerning overall survival but a lower rate of complications. The laparoscopic approach may be advantageous concerning the major drawback of RFA which is still the rate of local failure as shown by a meta-analysis of local recurrences.

Method

Indication for RFA was HCC in liver cirrhosis either as a definite therapy or as a bridging procedure for transplantation if the expected waiting time exceeded 6 months. Laparoscopic ultrasound, standardized algorithm of laparoscopic RFA procedure, track ablation and a Trucut biopsy were performed. The postoperative follow-up was done according to institutional standards. Patient data and parameters of laparoscopic RFA were prospectively documented, analyzed and compared with the results of previously published series found in a Medline search.

Results

34 patients were treated by laparoscopic RFA. The average time of follow-up was 36.9?±?28.3 months. There was no procedure-related mortality or surgical complications. An upstaging of the tumor stage by laparoscopic ultrasound was achieved in 32 % of the patients. The overall survival of these patients was 44.7?±?6.9 months. The intrahepatic recurrence rate was 61.8 % based on the number of patients treated. The results have been analyzed and compared with six independent papers identified in a Medline search that report on the treatment of patients with HCC in a liver cirrhosis by laparoscopic RFA with a mean follow-up of 12 or more months.

Conclusions

Laparoscopic RFA is a feasible and reliable therapy for unresectable HCCs in patients with cirrhosis. The laparoscopic RFA combines the advantage of a minimally invasive procedure concerning liver dysfunction with the ability of an accurate intraoperative staging by laparoscopic ultrasound.     

Improved Results of a Surgical Resection for the Recurrence of Hepatocellular Carcinoma After Living Donor Liver Transplantation

Purpose

This study was designed to analyze the clinical outcomes of the recurrence of hepatocellular carcinoma (HCC) after living donor liver transplantation (LDLT) and to evaluate the efficacy of a surgical resection in treating such a recurrence.

Methods

A total of 101 adult LDLT recipients with HCC between 1996 and 2007, including 17 who had recurrent HCC, were reviewed. The endpoints analyzed were survival from time of transplant and survival from time of recurrence. Recipient demographics, laboratory valuables, and tumor characteristics were analyzed. Any medical or surgical treatments that had been administered for any recurrence also were considered.

Results

The mean duration until the initial recurrence after LDLT and the mean duration until death after the initial recurrence were 12.9 months and 12.0 months, respectively. A univariate analysis showed that gender, interferon therapy, early posttransplant tumor recurrence, and eligibility for a surgical resection all had a beneficial impact on survival from tumor recurrence. A surgical resection of tumor relapse was the most important variable in our study, and therefore the patients were divided into two groups: surgical therapy group (n = 9), and nonsurgical therapy group (n = 7). Interestingly, the overall survival rates of the surgical group were significantly better than those of the nonsurgical group and were similar to that of the patients without HCC recurrence.

Conclusions

Surgical therapy might be useful for patients who experience a recurrence of HCC after LDLT to improve their outcome, when such treatment is available.     

Infection with Hepatitis C Virus is an Adverse Prognostic Factor after Liver Resection for Early-stage Hepatocellular Carcinoma

Introduction

Recent data support liver resection (LR) as first-line approach in patients with preserved liver function who have resectable/transplantable hepatocellular carcinoma (HCC). This study was designed to evaluate the outcome of LR in patients with transplantable HCC.

Methods

Between 1998 and 2009, 75 patients (65 men, mean age 61 ± 11 years) with HCC eligible for liver transplantation (LT) underwent LR. The underlying hepatic disease was related to hepatitis C (HCV) in 30 (40 %) patients, hepatitis B (HBV) in 15 (20 %) patients, alcohol abuse in 26 patients (36 %) and other in 10 patients (13 %). Fifty-five (73 %) patients had cirrhosis. Intermittent clamping of the hepatic pedicle was used in 41 (55 %) patients. Treatment of recurrence by salvage LT was performed in 6 (8 %) patients.

Results

Operative morbidity and mortality rates were 37 and 5  % respectively. At 1, 3, and 5 years, overall (OS) and disease-free (DFS) survival rates were 81, 69,55 and 56, 31, and 21 %, respectively. On multivariate analysis, HCV infection was the only independent factor associated with decreased OS (p = 0.02). On multivariate analysis, HCV infection (p = 0.05) and intermittent hepatic pedicle clamping (p = 0.003) were associated with decreased DFS. The 1-, 3-, and 5-year OS and DFS rates in patients with HCV-related HCC were 69, 53, 38 and 50, 18, and 9% respectively.

Conclusions

Overall and disease-free survival after liver resection in patients with HCV-related HCC and preserved liver function is poor. Primary LT should be offered to these patients.     

Shared Decision Making in Breast Cancer: National Practice Patterns of Surgeons

Background

The purpose of this study was to assess national practices of surgeons who treat breast cancer in order to identify opportunities to improve patient education.

Methods

In June 2012, the membership of the American Society of Breast Surgeons (ASBrS) (n = 2,818) was surveyed via email questionnaire to evaluate their current practice of shared decision making and informed consent for breast cancer patients.

Results

A total of 737 members (26 %) responded, including 384 breast surgeons and 306 general surgeons, 13 midlevel providers, and 25 other specialists. It was found that 90 % of surgeons spent more than 30 min meeting with a new cancer patient, and of these, 30 % spent more than an hour. Surgeons who spent more than 1 h face-to-face with a new cancer patient reported higher levels of overall patient knowledge compared with those who spent less (mean = 3.80 vs. 3.64 of 5; p = 0.001). Also, 89 % of respondents reported using educational tools, of whom more than 90 % used written tools. In addition, 65 % of members stated an interest in a free online educational tool if available and indicated a preference for a flexible tool that could be used by the patient alone or with a nurse.

Conclusions

While practice patterns may vary, our results reveal that one-third of surgeons spend at least 1 h in consultation with a new breast cancer patient. More time spent translated to a higher perceived patient understanding of their disease and treatment options. Although the majority of surgeons currently use written materials, there was clear support for a free online educational tool.     

Factors Influencing Surgeons’ Intraoperative Leadership: Video Analysis of Unanticipated Events in the Operating Room

Background

The achievement of surgical goals and the successful functioning of operating room (OR) teams are dependent on leadership. The attending surgeon is a team leader during an operation, with responsibility for task accomplishment by the clinical team. This study examined surgeons’ leadership behaviors during surgical procedures, with particular reference to the effect of intraoperative events on leadership.

Methods

Videos of operations (n = 29) recorded at three UK teaching hospitals were analyzed to identify and classify surgeons’ intraoperative leadership behaviors using the Surgeons’ Leadership Inventory. The frequency and type of leadership behaviors were compared before and after the point of no return (PONR) (n = 24), and during an unexpected intraoperative event (n = 5).

Results

Most of the surgeons’ leadership behaviors were directed toward the resident during an operation. No significant differences were found for the overall number or type of leadership behaviors pre- and post-PONR. The frequency of leadership behaviors classified as “Training” and “Supporting others” significantly decreased during an unanticipated intraoperative event.

Discussion

Overall, surgeons engaged in the same leadership behaviors throughout the course of an operation unless they were dealing with an unanticipated event. Surgeons appeared to adopt a “one size fits all” leadership style approach regardless of the team or situation. Additionally, surgeons seemed to limit their intraoperative leadership focus to other surgeons rather than to the wider OR team.     

Rating and issues of mechanical anastomotic staplers in surgical practice: a survey of 241 Japanese gastroenterological surgeons

Purpose

Commercially available mechanical devices for gastrointestinal anastomosis are mostly made in overseas. Japanese female surgeons have described these devices as being too large and difficult to handle. This study investigated the degree of satisfaction and problems experienced by Japanese surgeons in using various staplers for mechanical anastomosis.

Methods

A questionnaire was prepared and sent via email to 5,537 members of the Japanese Society of Gastroenterological Surgery. The questionnaire included sex, age, surgical glove size, degree of satisfaction with various mechanical staplers, stress felt when using the staplers in anastomosis, and problems regarding the devices.

Results

Valid responses were received from 241 respondents (167 males, 74 females, response rate 4.9 %). The satisfaction rate ranged from 0 to 100 %. The average glove size in males was significantly larger than that in females (median: 7.0 versus 6.0; P < 0.0001). Surgeons with glove size 6.0 or smaller felt stress more frequently than those with size 6.5 or larger (median: 40 vs. 20 %; P < 0.0001). Surgeons with glove size 6.0 and smaller experienced more difficulties during firing and releasing.

Conclusion

The satisfaction rates with currently available mechanical staplers were low. Japanese surgeons with small hands felt more stress when using the staplers. Ergonometric consideration is necessary in stapler design.
