ABSTRACT

Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory disease. IgG4-RD can affect any organ system, including the pancreas, bile ducts, salivary glands, mesentery, and retroperitoneum. On the other hand, small intestine involvement is extremely rare. This paper describes a case of IgG4-RD involving the small bowel, particularly at the distal ileum. An 81-year-old female was admitted to the authors’ hospital complaining of abdominal pain, dyspepsia, and hematochezia. The laboratory tests, including tumor markers and IgG4, were within normal limits. A colonoscopy did not show any abnormal findings. Abdominal computed tomography revealed segmental aneurysmal dilatation and wall thickening at the distal ileum, suggesting malignant conditions, such as small bowel lymphoma. The patient underwent an exploratory laparoscopy and ileocecectomy to differentiate a malignancy. A histopathology examination revealed dense lymphoplasmacytic infiltration, storiform fibrosis, and IgG4-positive plasma cells (>50 per high power field). The patient was finally diagnosed with IgG4-RD. The patient was followed up in the outpatient clinic for five years without recurrence. This paper suggests that a radical resection without maintenance therapy can be a treatment option, particularly when the IgG4-RD manifests as a localized gastrointestinal tract lesion.

ABSTRACT

Background/Aims@#This study aimed to investigate the patterns of preferred endoscopic procedure types and techniques for managing difficult common bile duct (CBD) stones in South Korea. @*Methods@#The Committee of Policy and Quality Management of Korean Pancreatobiliary Association (KPBA) conducted a survey containing 19 questions. Both paper and online surveys were carried out; with the paper survey being conducted during the 2019 Annual Congress of KPBA and the online survey being conducted through Google Forms from April 2020 to February 2021. @*Results@#The response rate was approximately 41.3% (86/208). Sixty-two (73.0%) worked at tertiary hospitals or academic medical centers, and 60 (69.7%) had more than 5 years of endoscopic retrograde cholangiopancreatography experience. The preferred size criteria for large CBD stones were 15 mm (40.6%), 20 mm (31.3%), and 30 mm (4.6%). For managing of large CBD stones, endoscopic papillary large balloon dilation after endoscopic sphincterotomy was the most preferred technique (74.4%). When performing procedures in those with bleeding diathesis, 64 (74.4%) respondents favored endoscopic papillary balloon dilation (EPBD) alone or EPBD with small endoscopic sphincterotomy. Fifty-five respondents (63.9%) preferred the doubleguidewire technique when faced with difficult bile duct cannulation in patients with periampullary diverticulum. In surgically altered anatomies, cap-fitted forward viewing endoscopy (76.7%) and percutaneous transhepatic cholangioscopy (48.8%) were the preferred techniques for Billroth-II anastomosis and total gastrectomy with Roux-en-Y anastomosis, respectively. @*Conclusions@#Most respondents showed unifying trends for the management of difficult CBD stones. The current practice patterns could be used as basic data for clinical quality improvements in the management of difficult CBD stones.

ABSTRACT

Background/Aims@#Although endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) and fine needle biopsy (FNB) are widely used for tissue acquisition of pancreatic solid mass, the optimal strategy of this procedure has not been established yet. The aim of this nationwide study was to investigate the current practice patterns of EUS-FNA/FNB for pancreatic solid mass in Korea. @*Methods@#The Policy-Quality Management of the Korean Pancreatobiliary Association (KPBA) developed a questionnaire containing 22 questions. An electronic survey consisting of the questionnaire was distributed by e-mail to members registered to the KPBA. @*Results@#A total of 101 respondents completed the survey. Eighty respondents (79.2%) performed preoperative EUS-FNA/FNB for operable pancreatic solid mass. Acquire needles (60.4%) were used the most, followed by ProCore needles (47.5%). In terms of need size, most respondents (>80%) preferred 22-gauge needles regardless of the location of the mass. Negative suction with a 10-mL syringe (71.3%) as sampling technique was followed by stylet slow-pull (41.6%). More than three needle passes for EUS-FNA/FNB was performed by most respondents (>80%). The frequency of requiring repeated procedure was significantly higher in respondents with a low individual volume (<5 per month, p=0.001). Prophylactic antibiotics were routinely used in 39 respondents (38.6%); rapid on-site pathologic evaluation was used in 6.1%. @*Conclusions@#According to this survey, practices of EUS-FNA/FNB for pancreatic solid mass varied substantially, some of which differed considerably from the recommendations present in existing guidelines. These results suggest that the development of evidence-based quality guidelines fitting Korean clinical practice is needed to establish the optimal strategy for this procedure.

ABSTRACT

Background/Aims@#This study aimed to evaluate the characteristics of endoscopic retrograde cholangiopancreatography (ERCP) or endoscopic ultrasonography (EUS)-related adverse events (AEs) that eventually lead to medical disputes or claims on medical professional liability. @*Methods@#Medical disputes for ERCP/EUS-related AEs filed in the Korea Medical Dispute Mediation and Arbitration Agency between April 2012 and August 2020 were evaluated using corresponding medical records. AEs were categorized into three sections: procedure-related, sedation-related, and safety-related AEs. @*Results@#Among a total of 34 cases, procedure-related AEs were 26 (76.5%; 12 duodenal perforations, 7 post-ERCP pancreatitis, 5 bleedings, 2 perforations combined with post-ERCP pancreatitis); sedation-related AEs were 5 (14.7%; 4 cardiac arrests, 1 desaturation), and safety-related AEs were 5 (8.8%; 1 follow-up loss for stent removal, 1 asphyxia, 1 fall). Regarding clinical outcomes, 20 (58.8%) were fatal and eventually succumbed to AEs. For the types of medical institutions, 21 cases (61.8%) occurred at tertiary or academic hospitals, and 13 (38.2%) occurred at community hospitals. @*Conclusions@#The ERCP/EUS-related AEs filed in Korea Medical Dispute Mediation and Arbitration Agency showed distinct features: duodenal perforation was the most frequent AE, and clinical outcomes were fatal, resulting in at least more than permanent physical impairment.

ABSTRACT

Purpose@#Vascular invasion is a well-known independent prognostic factor in colon cancer and tumor sidedness is also being considered a prognostic factor. The aim of this study was to compare the oncological impact of vascular invasion depending on the tumor location in stages I to III colon cancer. @*Methods@#A retrospective analysis was performed using data from patients who underwent curative resection between 2004 and 2015. Patients were divided into right-sided colon cancer (RCC) and left-sided colon cancer (LCC) groups according to the tumor location. Disease-free survival (DFS) and overall survival (OS) were compared between the RCC and LCC groups, depending on the presence of vascular invasion. @*Results@#A total of 793 patients were included, of which 304 (38.3%) had RCC and 489 (61.7%) had LCC. DFS and OS did not differ significantly between the RCC and LCC groups. Vascular invasion was a poor prognostic factor for DFS in both RCC (hazard ratio [HR], 2.291; 95% confidence interval [CI], 1.186–4.425; p = 0.010) and LCC (HR, 1.848; 95% CI, 1.139–2.998; p = 0.011). Additionally, it was associated with significantly worse OS in the RCC (HR, 3.503; 95% CI, 1.681–7.300; p < 0.001), but not in the LCC group (HR, 1.676; 95% CI, 0.885–3.175; p = 0.109). Multivariate analysis revealed that vascular invasion was independently poor prognostic factor for OS in the RCC (HR, 3.186; 95% CI, 1.391–7.300; p = 0.006). @*Conclusion@#This study demonstrated that RCC with vascular invasion had worse OS than LCC with vascular invasion.

ABSTRACT

Purpose@#Enhanced Recovery After Surgery (ERAS) reduces postoperative complications and shortens hospital stays. We aimed to describe the implementation and improvement of ERAS protocols in our institution through a multidisciplinary team approach. @*Methods@#A multidisciplinary team comprised of colorectal surgeons, anesthesiologists, nurses, pharmacists, nutritionists, and a performance improvement team was launched to develop the ERAS protocol. The ERAS protocol was followed in patients who underwent colonic and rectal surgery between January and November 2017. The ERAS protocol comprised 22 elements in the preoperative, intraoperative, and postoperative phases. After the initial application, ERAS compliance was monitored and audited every 4–6 months and improvements made as necessary. @*Results@#The length of hospital stay significantly decreased after the application of the ERAS protocols for colon cancer in 2017 and 2018. And there was no significant difference in the duration of hospital stay after applying the rectal cancer ERAS protocol. Moreover, after starting the colon ERAS, there was a significant decrease in the complication rate. Since December 2017, there was a continuous increase in the colorectal ERAS clinical pathway application rate, which remained high (>90%). The patient compliance rate significantly increased between 2017 and 2018, but slightly decreased again in 2019. @*Conclusion@#The application and continual improvement of an ERAS protocol are crucial. Improving compliance may result in better clinical outcomes. Additionally, the basic guidelines of ERAS must be applied and developed according to each hospital’s situation based on the team approach.

ABSTRACT

Background/Aims@#The study aimed to investigate the current practice patterns in the management of pancreatic cystic neoplasms in Korea. @*Methods@#An electronic survey was systematically distributed by email to members of the Korean Pancreatobiliary Association from December 2019 to February 2020. @*Results@#In total, 115 (110 gastroenterologists, five surgeons) completed the survey, 72.2% of whom worked in a tertiary/academic medical center. Most (65.2%) followed the 2012/2017 International Association of Pancreatology guidelines for the management of pancreatic cystic neoplasms. A gadolinium-enhanced magnetic resonance imaging/magnetic resonance cholangiopancreatography was the most common first-line diagnostic modality (42.1%), but a contrast-enhanced computed tomography scan was preferred as a subsequent surveillance tool (58.3%). Seventy- four percent of respondents routinely performed endoscopic ultrasound-guided fine needle aspiration for pancreatic cystic neoplasms with suspicious mural nodules. Endoscopic ultrasound-guided fine needle aspiration cytology (94.8%) and cystic fluid carcinoembryonic antigen (95.7%) were used for cystic fluid analysis. Most (94%) typically recommended surgery in patients with high-risk stigmata, but 18.3% also considered proceeding with surgery in patients with worrisome features. Most (96.5%) would continue surveillance of pancreatic cystic neoplasms for more than 5 years. @*Conclusions@#According to this survey, there was variability in the management of pancreatic cystic neoplasms among the respondents. These results suggest that the development of evidence-based guidelines for pancreatic cystic neoplasms that fit the Korean practice is needed to create an optimal approach to the management of pancreatic cystic neoplasms.

ABSTRACT

Purpose@#The standard of care for early rectal cancer is radical surgery; however, it carries high postoperative morbidity. This study aimed to assess the short-term and oncological outcomes of local excision and adjuvant radiotherapy in patients with high-risk pathological stage (p) T1 rectal cancer. @*Methods@#Fifty-five patients underwent local excision with adjuvant radiotherapy or radical resection for high-risk T1 rectal cancer. Patients with adenocarcinoma within 10 cm from the anal verge; pT1 with high-risk features (grade 3–4); a tumor size of ≥3 cm; a positive margin; a lymphovascular or perineural invasion; or a submucosal invasion depth of ≥SM2 were included. @*Results@#The rates of postoperative complications and stoma formation were higher in the radical surgery group (P = 0.021 and P = 0.003, respectively). No significant differences were observed in the overall survival and disease-free survival (DFS) between the 2 groups (P = 0.301 and P = 0.076, respectively). Vascular invasion was a significantly poor prognostic factor for DFS (P = 0.033). The presence of 3 or more high-risk features was associated with a poor DFS (P = 0.002). @*Conclusion@#Local excision with adjuvant radiotherapy significantly reduces the risk of complications and stoma formation. It is also an alternative option for patients with fewer than 3 high-risk features.

ABSTRACT

Purpose@#The prognostic factors in obstructive colon cancer have not been clearly identified. We aimed to identify the prognostic factor to establish optimal treatment strategy in obstructive colon cancer. @*Methods@#Patients who underwent surgery for primary colon cancer in stages II and III with symptomatic obstruction from 2004 to 2010 in six hospitals were retrospectively collected. Clinicopathological and surgical outcomes were compared between stent insertion and emergent surgery group. Multiple regression analysis and survival curve analysis were used to identif y the prognostic factors in symptomatic obstructive colon cancer. @*Results@#Among 210 patients, 168 patients (80.0%) underwent stent insertion followed by surgery and 42 patients (20.0%) underwent emergent surgery. Laparoscopic approach (55.4% vs. 23.8%, p< 0.001) and adequate lymph node (LN) harvest (≥12) (93.5% vs. 69.0%, p < 0.001) were significantly higher in stent insertion group. In multiple regression analysis, emergent surgery (hazard ratio [HR], 2.153; 95% confidence interval [CI], 1.031–4.495), vascular invasion (HR, 6.257; 95% CI, 2.784–14.061), and omitting adjuvant chemotherapy (HR, 3.107; 95% CI, 1.394–6.925) were independent poor prognostic factors in 5-year overall survival, and N stage (N1: HR, 3.095; 95% CI, 1.316–7.284; N2: HR, 4.156; 95% CI, 1.671–10.333) was the only poor prognostic factor in 5-year disease-free survival. @*Conclusion@#In symptomatic obstructive colon cancer, emergent surgery, N stage, vascular invasion, and omission of adjuvant chemotherapy were independent poor prognostic factors. Stent insertion is suggested as the initial treatment for symptomatic obstructive colon cancer, and adjuvant chemotherapy is recommended, especially when vascular invasion or LN metastasis is confirmed.

ABSTRACT

Background/Aims@#Recently, the European Society of Gastrointestinal Endoscopy (ESGE) proposed criteria for “difficult biliary cannulation” during endoscopic retrograde cholangiopancreatography (ERCP). This study aimed to investigate the clinical relevance of the ESGE criteria from the perspective of post-ERCP pancreatitis (PEP). @*Methods@#An ERCP database was prospectively maintained between November 2014 and December 2015 across six teaching hospitals in South Korea. The ESGE criteria (biliary cannulation time, the number of cannulation attempts, and inadvertent pancreatic duct [PD] manipulation) were recorded in this database as well as other technical factors. Logistic regression analysis was used to identify risk factors for PEP. Then, the PEP prediction model was investigated using decision tree analysis. @*Results@#We analyzed 1,067 consecutive patients with naïve papilla. The overall rate of PEP was 6.6%. Multivariate analysis revealed that female sex (odds ratio [OR], 1.860; 95% confidence interval [CI], 1.124 to 3.078), a selective biliary cannulation duration >5 minutes (OR, 3.282; 95% CI, 1.641 to 6.566), and inadvertent PD manipulation (OR, 2.614; 95% CI, 1.480 to 4.617) were significant factors affecting PEP. Decision tree analysis revealed that biliary cannulation time (χ2 =49.857, p5 minutes, and >5 minutes with inadvertent PD manipulation, respectively. @*Conclusions@#Biliary cannulation time and inadvertent PD manipulation could be relevant indicators of PEP, and 5 minutes might be used as a cutoff value for the implementation of the rescue cannulation technique.

ABSTRACT

Purpose@#The objective of this study was to compare the perioperative outcomes between single-incision laparoscopic appendectomy (SILA) and 3-port conventional laparoscopic appendectomy (CLA) in enhanced recovery after surgery (ERAS) protocol. @*Methods@#Of 101 laparoscopic appendectomy with ERAS protocol cases for appendicitis from March 2019 to April 2020, 54 patients underwent SILA with multimodal analgesic approach (group 1) while 47 patients received CLA with multimodal analgesic approach (group 2). SILA and CLA were compared with the single institution’s ERAS protocol. To adjust for baseline differences and selection bias, operative outcomes and complications were compared after propensity score matching (PSM). @*Results@#After 1:1 PSM, well-matched 35 patients in each group were evaluated. Postoperative hospital stays for patients in group 1 (1.2 ± 0.8 vs. 1.6 ± 0.8 days, P = 0.037) were significantly lesser than those for patients in group 2. However, opioid consumption (2.0 mg vs. 1.4 mg, P=0.1) and the postoperative scores of visual analogue scale for pain at 6 hours (2.4±1.9 vs. 2.8 ± 1.4, P = 0.260) and 12 hours (2.4 ± 2.0 vs. 2.9 ± 1.5, P = 0.257) did not show significant difference between the 2 groups. @*Conclusion@#SILA resulted in shortening the length of hospitalization without increase in complications or readmission rates compared to CLA with ERAS protocol.

ABSTRACT

Laparoscopic complete mesocolic excision is the preferred approach for treating transverse colon cancer. Due to the anatomical complexity, mobilization and resection of the transverse colon can be technically challenging. This video demonstrates laparoscopic transverse colectomy using an articulating laparoscopic instrument for a 76-year-old female patient diagnosed with T-colon cancer.

ABSTRACT

Purpose@#Although there are many articles about single incision laparoscopic (SIL) hernioplasty, a large-scale study or article about its long-term outcome has not been reported yet. The aim of this study is to assess short- and long-term outcomes of SIL totally extraperitoneal (TEP) hernia repair with large number of cases. @*Methods@#A prospectively collected database containing details of 1,231 procedures in 1,129 consecutive patients who underwent SIL-TEP hernia repair between June 2010 and December 2017 at a single institution was retrospectively analyzed. SIL-TEP hernia repair was performed using a glove single port device and standard laparoscopic instruments.Recurrence rate of SIL-TEP hernia repair was analyzed by a telephone questionnaire. @*Results@#Among 1,129 patients, 1,027 (91.0%) had unilateral hernia and 102 (9.0%) had bilateral hernia. There were 12 (1.1%) conversions to single or 3 ports laparoscopic transabdominal preperitoneal hernioplasty or Lichtenstein repair. Mean operative time was 40.3 minutes for unilateral hernia and 61.6 minutes for bilateral hernia. Intraoperative complication rate was 21.8%. Most intraoperative complications were peritoneum or sac tearing (20.1%). Postoperative complications occurred in 97 (8.6%) cases, most of which were minor morbidity except for 1 mesh infection. Five-year recurrence rate was 4%. @*Conclusion@#SIL-TEP hernia repair is safe and technically feasible with acceptable short- and long-term outcomes. Largescale randomized controlled trials comparing SIL-TEP hernia repair with conventional laparoscopic TEP are needed to confirm these results.

ABSTRACT

Purpose@#Diverting stoma (DS) and transanal tube (TAT) are the 2 main procedures for reducing anastomotic leak (AL) in rectal cancer surgery. However, few studies have compared the protective effect of the 2 modalities against AL. @*Methods@#Total of 165 patients with mid rectal cancer, who underwent curative resection from 2012 to 2017, were included.Clinical characteristics and outcomes were compared. Risk factors for AL were identified using multivariate analysis. @*Results@#The DS group had lower tumor location, higher rates of neoadjuvant concurrent chemoradiotherapy, and longer operative time than the TAT group. However, the level of the anastomosis did not show statistically significant differences (DS: 4.6 cm vs. TAT: 4.9 cm, P = 0.061). AL occurred in 14 of the 165 patients (8.5%), with 10 (10.2%) in the DS group and 4 (6.0%) in the TAT group (P = 0.405). On multivariate analysis, only low body mass index (BMI) and smoking were significantly related to AL. Neither the protection method nor neoadjuvant chemoradiotherapy demonstrated statistical differences in AL. Seven of 10 patients in the DS group who experienced AL were treated conservatively, while all 4 in the TAT group underwent reoperation. @*Conclusion@#TAT seems to have comparable protective effect against AL to DS. However, in AL, DS appeared to be more effective in preventing reoperation. Therefore, DS is recommended in patients with low BMI or smoking, and with an expected higher probability of morbidity or mortality in case of reoperation. In other cases, TAT may be considered as an alternative to DS.

ABSTRACT

We aimed to show that a standardized step-by-step robotic approach using surgical landmarks could make lateral pelvic lymph node dissection (LPND) less complicated. We performed robot-assisted LPND consisting of 4 steps using surgical landmarks. The first step is a dissection of uretero-hypogastric fascia, which envelopes the ureter and the hypogastric nerve. The second step is a dissection of the medial side of the external iliac vein located at the lateral border of the obturator lymph nodes (LNs) group. The third step is a dissection of the vesico-hypogastric fascia, which is at the medial border of the obturator LNs group. The final step is a dissection of the internal iliac artery until the Alcock’s canal. Indocyanine green was injected just before surgery around the dentate line to identify the lateral pelvic LNs. Standardization using a robotic approach for LPND guided by surgical landmarks allows a safer and more effective surgery.

ABSTRACT

Background/Aims@#The work environment in which endoscopic retrograde cholangiopancreatography (ERCP) is conducted has influence on its efficacy and safety. We aimed to assess the current status of ERCP work environments and to investigate the trends associated with the basic techniques of ERCP in Korea. @*Methods@#The work environment and information on the basic techniques of ERCP were acquired by the Korean Pancreatobiliary Association (KPBA) through a national survey in 2019. The survey was performed at the KPBA conference in 2019. The contents of survey comprised of the current environment of ERCP, preparation before ERCP, and the preferred basic techniques used in ERCP. @*Results@#Completed questionnaires were returned from 84 KPBA members. The mean ERCP volume per year was approximately 500. About 60% (50/84) reported that they worked with a dedicated ERCP team with experienced nurses. Two-thirds (57/84, 68%) answered that they had a fluoroscopy room used solely for ERCP procedures. All respondents intravenously hydrated the patient to prevent post-ERCP pancreatitis (84/84, 100%).
