Hybrid Laparoscopic and Robotic Hepatopancreaticoduodenectomy for CholangiocarcinomaAbstractIntroduction
Combined hepatic resection and pancreaticoduodenectomy is the treatment of choice for patient with extensive horizontal-spreading cholangiocarcinoma involving both the perihilar bile duct and the intrapancreatic distal bile duct.1–3 This surgical procedure is extremely complex, and incurs a high risk of postoperative morbidity and mortality.4 However, in recent years, this complicated high-risk operation can be safely performed in well-selected patients.5 However, as we know, none of these operations have been reported as minimally invasive surgery.
Patient and Methods
A 73-year-old female presented with jaundice and was diagnosed with cholangiocarcinoma. The preoperative image studies revealed a 4.3-cm-long diffuse, infiltrative cholangiocarcinoma from the hilar bile duct to the intrapancreatic bile duct without major vascular invasion. The patient was scheduled to undergo left hepatectomy with caudate lobectomy and pancreaticoduodenectomy to obtain a free resection margin. In order to maximize the efficiency of each surgical modality, we designed a hybrid method of laparoscopic resection and robotic reconstruction for this complicated surgery with a long operation time. A 12-mm port was placed at the subxiphoid area, which was utilized for laparoscopic CUSA during the liver resection. Three 12-mm ports around the umbilicus and an 8-mm robotic port at the right flank were placed. In the resection phase, pancreaticoduodenectomy was performed first, followed by hilar dissection and liver resection in en bloc manner. Here, a hanging maneuver was helpful for the complete resection of the caudate lobe in environment with the large specimen attached. In reconstruction phase, the right flank 8-mm port and the left side 12-mm port (using the double docking technique) were used for docking of two robotic working arms.
Results
The total operation time was 510 min, and the estimated blood loss was 350 mL without transfusion. The patient’s postoperative recovery was smooth, except for a mild fever due to cystitis, and she was discharged on the 16th postoperative day. Permanent pathologic examination revealed a disease-free proximal bile duct margin, but a metastasis was discovered in one regional lymph node metastasis from 18 retrieved lymph nodes. The patient is receiving adjuvant gemcitabine chemotherapy and regular surveillance. We performed two consecutive cases and the perioperative outcomes were summarized in the attached video.
Conclusion
Hepatopancreaticoduodenectomy has a long operative time, involves complicated anatomical structures and difficulty of R0 resection, and it is a remaining frontier of minimally invasive surgery. However, we expect that highly selected patients can carefully undergo minimally invasive surgery if the advantages of the currently available surgical methods are well utilized.

Should All Stage N3b Patients with Advanced Gastric Cancer Be Considered Equivalent? A 30-Year Single Center StudyAbstractPurpose
To investigate the survival of stage N3b patients with advanced gastric cancer (AGC) after radical surgery and to evaluate the TNM staging of subgroups of stage N3b patients.
Methods
We reviewed the data of 222 stage N3b patients with AGC who underwent D2/D3 radical surgery. Depending on the number of metastatic lymph nodes (MLNs), we divided N3b patients into several groups and compared the survival differences among them. We found that survival of patients with 16–20 MLNs was better than that of patients with ≥ 21 MLNs. Therefore, we divided the N3b patients into two subgroups and defined patients with 16–21 MLNs as N3b1 and patients with ≥ 21 MLNs as N3b2. Then, we compared survival differences between the two groups and their subgroups. Patients who underwent palliative surgery served as the reference group. In addition, we selected stage IIIB, IIIC, and IV patients from the same database to properly re-classify the N3b subgroups in the TNM staging system.
Results
Survival differed significantly between the new N3b1and N3b2 groups and between the new N3b1 group and the palliative group. However, the survival of the new N3b2 group was similar to that of the palliative group. Comparisons of survival according to T staging revealed similarities between the following groups: (1) stages T2–3N3b1 and IIIB, (2) stages T4N3b1 and IIIC, and (3) stages T2–4N3b2 and IV.
Conclusions
All stage N3b patients with AGC should not be considered equivalent. A significant difference in survival was observed between stage N3b1 and N3b2 patients after radical surgery, while the survival of stage N3b2 patients was similar to that of patients who undergo palliative surgery. We recommend re-classifying stage T2–3N3b1 as TNM stage IIIB, stage T4N3b1 as stage IIIC, and T2–4N3b2 as stage IV.

Slow Gait Speed Is a Risk Factor for Complications After Hepatic ResectionAbstractPurpose
The aims of this study were to clarify the relationship of gait speed, hand grip strength, and skeletal muscle mass with complications after hepatic resection and to identify risk factors for complications in patients who underwent hepatic resection.
Methods
We evaluated the risk factors for complications after hepatic resection in 154 consecutive patients. Preoperative factors included gait speed, hand grip strength, and skeletal muscle mass. The gait speed and hand grip strength of patients were measured by physical therapists, and skeletal muscle mass was measured by computed tomography. Multivariate logistic regression analyses using preoperative factors were performed to assess predictors of the development of complications after hepatic resection.
Results
Thirty-three patients (21.4%) developed complications after hepatic resection. These patients had a significantly lower serum albumin level (p = 0.015), slower gait speed (p = 0.007), higher rate of hepatic resection ≥ 2 Couinaud segments (p = 0.014), and lower rate of laparoscopic hepatic resection (p = 0.017) than patients without complications. Multivariate analysis revealed that a gait speed ≤ 1.10 m/s and a serum albumin level of ≤ 4.0 g/dl were independent risk factors for complications after hepatic resection.
Conclusions
Slow gait speed and low serum albumin level are significant risk factors for complications after hepatic resection. These data will be helpful for perioperative patient management.

Cholecystectomy Risk in Crohn’s Disease Patients After Ileal Resection: a Long-term Nationwide Cohort StudyAbstractBackground
The risk of gallstone disease necessitating cholecystectomy after ileal resection (IR) in Crohn’s disease (CD) patients is not well established. We studied the incidence, cumulative and relative risk of cholecystectomy after IR in CD patients, and associated risk factors.
Methods
CD patients with a first IR between 1991 and 2015 were identified in PALGA, a nationwide pathology database in the Netherlands. Details on subsequent cholecystectomy and IR were recorded. Yearly cholecystectomy rates from the general Dutch population were used as a reference.
Results
A cohort of 8302 (3466 (41.7%) males) CD patients after IR was identified. During the 11.9 (IQR 6.3–18.0) years median follow-up, the post-IR incidence rate of cholecystectomy was 5.2 (95% CI 3.5–6.4)/1000 persons/year. The cumulative incidence was 0.5% at 1 year, 2.4% at 5 years, 4.6% at 10 years, and 10.3% after 20 years. In multivariable analyses, female sex (HR 1.9, CI 1.5–2.3), a later calendar year of first IR (HR/5-year increase, HR 1.27, CI 1.18–1.35), and ileal re-resection (time-dependent HR 1.37, CI 1.06–1.77) were associated with cholecystectomy. In the last decade, cholecystectomy rates increased and were higher in our postoperative CD population than in the general population (relative incidence ratio 3.13 (CI 2.29–4.28; p < 0.0001) in 2015).
Conclusions
Although higher in females, increasing in recent years, and higher than in the general population, the overall risk of cholecystectomy in CD patients following IR is low and routine prophylactic measures seem unwarranted.

Importance of Resection Margins in the Treatment of Rectal Adenomas by Transanal Endoscopic SurgeryAbstractBackground
Polypectomy is the gold standard for treating colorectal adenomas up to 2 cm in size. For larger lesions, various procedures ranging from endoscopy to transanal surgery can be performed and achieve varying results for en bloc resection and recurrence. There are no clear guidelines for dealing with involved resection margins. We assess the recurrence of rectal adenomas operated using TEM with full-thickness wall excision with or without free resection margins and define optimal endoscopic follow-up.
Method
Observational study with prospective data collection, including patients undergoing TEM between 6/2004 and 11/2017, with definitive diagnosis of rectal adenoma. Data on epidemiological, preoperative, surgical, postoperative, pathological, and follow-up variables were recorded. Univariate analysis, follow-up risk function, and multivariate logistic regression analysis were performed to detect risk factors for recurrence.
Results
TEM was indicated in 736 patients; 481 adenomas were identified in the preoperative biopsy, of which 95 were infiltrating adenocarcinomas (19.8%) in the definitive pathology study. With a minimum follow-up of 1 year, 372 patients were included. Pathology study showed free margins in 324 (87%). Recurrences were recorded in 15 patients (4%), up to 18 months in the free margins group and up to 24 months in the involved margins group. Thirteen patients with recurrence (86.6%) were treated with TEM. No predictors of recurrence were found in the multivariate analysis.
Conclusion
TEM is the technique of choice for treating rectal adenomas and recurrences, achieving a low relapse rate. Follow-up must be adapted to resection margins and should be extended to 24 months.
