ABSTRACT

Sufficient liver regeneration after a right hepatectomy is important in living donors for preventing postoperative hepatic insufficiency; however, it differs for each living donor so we investigated the clinical factors affecting the rate of liver regeneration after hepatic resection. This retrospective case-control study investigated fifty-four living donors who underwent a right hepatectomy from July 2015 to March 2023. Patients were classified into 2 groups by the remnant/total volume ratio (RTVR): Group A (RTVR < 30%, n = 9) and Group B (RTVR ≥ 30%, n = 45). The peak postoperative level of total bilirubin was more elevated in Group A than in Group B (3.0 ± 1.1 mg/dL vs. 2.3 ± 0.8 mg/dL, p = 0.046); however, no patients had hepatic insufficiency or major complications. The rates of residual liver volume (RLV) growth at Postoperative Week 1 (89.1 ± 26.2% vs. 53.5 ± 23.7%, p < 0.001) were significantly greater in Group A, and its significant predictors were RTVR (ß = -0.478, p < 0.001, variance inflation factor (VIF) = 1.188) and intraoperative blood loss (ß = 0.247, p = 0.038, VIF = 1.182). In conclusion, as the RLV decreases, compensatory liver regeneration after hepatic resection becomes more prominent, resulting in comparable operative outcomes. Further studies are required to investigate the relationship between hematopoiesis and the rate of liver regeneration.

ABSTRACT

Filter trocar designed to eliminate harmful smoke is also regarded as effective for improving surgical visualization. The aim of this study is to evaluate the efficacy of filter trocar in maintaining clear operative view. From 2019 to 2020, 100 patients underwent laparoscopic cholecystectomy and they were randomized to either the control or filter group. The primary end point was a laparoscopic operative view score (1, clear; 2, slightly blurry; 3, completely blurry) during gallbladder dissection from the liver bed when dissection was started (LV1), when dissection was half completed (LV2) and when dissection was completed (LV3). Between the control and filter groups, there were no significant differences in mean LV1 (1.44 vs. 1.40, p = 0.234) and LV3 (1.86 vs. 2.01, p = 0.880). There was no significant difference in the mean duration of suction after dissection (3.82 s vs. 3.67 s, p = 0.097) and the mean number of laparoscope removals from inside to outside the body to clean during gallbladder dissection from the liver bed (0.55 vs. 0.22, p = 0.963) or the mean amount of time required to dissect the gallbladder from the liver bed (221.58 s vs. 177.09 s, p = 0.253). The study demonstrated that filter trocar is not as effective as expected in the maintenance of clear operative view. Further study is needed to develop devices to improve clear surgical visualization.

ABSTRACT

Background: It is not well understood whether the severity of acute cholecystitis (AC) correlates with the extent of gallbladder (GB) inflammation or laboratory findings. This study aimed to assess whether the severity of AC, in accordance with the Tokyo Guidelines (TGs), is consistent with the extent of GB inflammation on histopathological and laboratory findings, including microbiological isolation in blood and bile. Methods: The medical records of patients who underwent cholecystectomy for AC between January 2017 and May 2020 were reviewed. Demographic data, laboratory findings, the microbiologic culture of blood and bile, the extent of GB inflammation, and stone composition were compared in accordance with the TGs. Results: A total of 217 patients were divided into three groups of increasing severity-Grade I (n = 146), Grade II (n = 51), and Grade III (n = 20)-in accordance with the TGs. The Grade III group contained significantly older patients compared with the Grade I or Grade II groups (Grade I, 56.9 ± 13.9; Grade II, 64.3 ± 15.4; Grade III, 69.9 ± 9.9; p-value < 0.001). Patients in the Grade III group showed significantly higher levels of CRP, WBC, creatinine, and bilirubin and lower levels of platelets and albumin compared with the Grade I or Grade II group. As the grade of severity increased, the rate of microbiological isolation in blood (Grade I, 0% [0/146]; Grade II, 2.0% [1/51]; Grade III, 20% [4/20]; p-value < 0.001) and bile (Grade I, 19.9% [29/146]; Grade II, 33.3% [17/51]; Grade III, 70% [14/20]; p-value < 0.001) also increased significantly. However, there were no significant differences in the extent of GB inflammation between grades. Conclusions: AC severity, as stated by the TGs, does not correlate with the extent of GB inflammation on histopathological and laboratory findings. However, microbiological isolation in blood and bile was increased proportionally to the grade of the TGs.

ABSTRACT

Background: This systematic review and meta-analysis with trial sequential analysis (TSA) aimed to compare perioperative outcomes of peripheral nerve blocks (PNBs) and spinal anesthesia (SA) in elective foot and ankle surgery. Methods: The study protocol was registered in PROSPERO (CRD42021229597). Researchers independently searched PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials for relevant randomized controlled trials (RCTs). Results: Analysis of nine RCTs (n = 802; 399 PNBs, 403 SA) revealed significantly shorter block performance times (WMD: 7.470; 95% CI 6.072 to 8.868), the onset of sensory (WMD: 7.483; 95% CI 2.837 to 12.130) and motor blocks (WMD: 9.071; 95% CI 4.049 to 14.094), durations of sensory (WMD: 458.53; 95% CI 328.296 to 588.765) and motor blocks (WMD: 247.416; 95% CI 95.625 to 399.208), and significantly higher postoperative analgesic requirements (SMD: -1.091; 95% CI -1.634 to -0.549) in the SA group. Additionally, systolic blood pressure (SBP) at 30 min (WMD: 13.950; 95% CI 4.603 to 23.298) was lower in the SA group. Conclusions: The SA demonstrated shorter block performance time, faster onset and shorter duration of sensory and motor blocks, higher postoperative analgesic requirements, and lower SBP at 30 min compared to PNBs in elective foot and ankle surgery.

ABSTRACT

The high incidence of hepatocellular carcinoma (HCC) recurrence after surgical resection worsens the long-term prognosis. Besides tumor-related factors, operative factors such as perioperative blood transfusion have been reported to be related to HCC recurrence. However, excessive intraoperative blood loss (IBL) always necessitates blood transfusion, where IBL and blood transfusion may influence oncologic outcomes. We enrolled 142 patients with newly diagnosed single HCC who underwent hepatic resection between March 2010 and July 2021. Patients were stratified into two groups by IBL volume: Group A (IBL ≥ 700 mL, n = 47) and Group B (IBL < 700 mL, n = 95). The clinic-pathologic findings, operative outcomes, and cumulative probability of tumor recurrence and overall survival were compared between the two groups. In the study, increased IBL (1351 ± 698 vs. 354 ± 166, p < 0.001) and blood transfusion (63.8% vs. 6.3%, p < 0.001) were common in Group A, with a greater HCC recurrence (p = 0.001) and poor overall survival (p = 0.017) compared to those in Group B. Preoperative albumin (hazard ratio [HR], 0.471; 95% confidence interval [CI], 0.244-0.907, p = 0.024), microvascular invasion (HR, 2.616; 95% CI, 1.298-5.273; p = 0.007), and IBL ≥ 700 mL (HR, 2.325; 95% CI, 1.202-4.497; p = 0.012) were significant risk factors for tumor recurrence after surgical resection for HCC. In conclusion, efforts to minimize IBL during hepatic resection are important for improving long-term prognosis in HCC patients.

ABSTRACT

Ascaris lumbricoides causes one of the most common soil-transmitted helminthiases globally. The worms mostly infect the human small intestine and elicit negligible or nonspecific symptoms, but there are reports of extraintestinal ectopic ascariasis. We describe a rare case of biliary ascariasis mistaken for biliary stent in a 72-year-old female patient with a history of liver resection. She visited our outpatient clinic complaining of right upper quadrant pain and fever for the past week. She had previously undergone left lateral sectionectomy for recurrent biliary and intrahepatic duct stones 2 years ago. Besides mildly elevated gamma-glutamyl transferase levels, her liver function tests were normal. Magnetic resonance cholangiopancreatography revealed a linear filling defect closely resembling an internal stent from the common bile duct to the right intrahepatic bile duct. A live female A. lumbricoides adult worm was removed by endoscopic retrograde cholangiopancreatography (ERCP). Despite a significant decrease of the ascariasis prevalence in Korea, cases of biliary ascariasis are still occasionally reported. In this study, a additional case of biliary ascariasis, which was radiologically misdiagnosed as the biliary stent, was described in a hepatic resection patient by the worm recovery with ERCP in Korea.

ABSTRACT

BACKGROUND: The prognostic impact of extrathyroidal extensions (ETE) on clinical outcomes has not been well studied in pediatric thyroid cancers. The aim of this study was to analyze the clinicopathological characteristics and clinical outcomes according to the extent of ETE in pediatric and adolescent thyroid cancers. METHODS: This study retrospectively reviewed 89 papillary thyroid carcinoma (PTC) patients less than 19 years of age who underwent total thyroidectomy with central neck dissections (CND) between 1997 and 2018. We compared the clinicopathological features among three groups: no ETE, microscopic ETE, and gross ETE. RESULTS: The median follow-up time was 111 months. The mean age was 15.3 years and the mean tumor size was 2.4 cm. Tumor sizes larger than 2 cm (OR = 9.2, p = 0.001), exhibited bilaterality (OR = 4.3, p = 0.006), were an aggressive variant (OR = 5.8, p = 0.006), and exhibited central lymph node metastasis (OR = 1.3, p = 0.018), lateral lymph node metastasis (OR = 9.2, p = 0.001), recurrence (OR = 3.9, p = 0.038), and distant metastasis (OR = 4.4, p = 0.016) were associated with gross ETE. There was no remarkable difference in clinicopathological characteristics between the no ETE group and microscopic ETE group, except for aggressive variants (OR = 5.5, p = 0.008). There was a significant difference in recurrence-free survival (RFS) rates according to the extent of ETE (p = 0.025). Furthermore, the distant metastasis-free survival curve presented a significant difference among the three groups (p = 0.018). Both microscopic ETE and gross ETE were significantly associated with worse prognoses in pediatric thyroid cancers. CONCLUSIONS: We recommend that microscopic ETE should be included in the intermediate risk category and that gross ETE should be stratified in the high risk group in future revisions of ATA pediatric guidelines.

ABSTRACT

PURPOSE: This study investigated the antiadhesive effects of Mediclore®, rosuvastatin, and a combination of Mediclore and rosuvastatin in a rat adhesion model. METHODS: The adhesion models (a total of 58 adult male rats) were divided into 4 groups. The control group (group C) received no special materials except for a saline. The experimental groups were treated with 5 mL of Mediclore (group M), rosuvastatin (group R), or rosuvastatin and Mediclore (group RM), and these materials were intraperitoneally placed under the incision. At postoperative day 14, the rats underwent re-laparotomy and adhesiolysis. Three investigators blinded to group assignment scored the extent of adhesion formation, the numbers of remote adhesions, and the extent of acute/chronic inflammation, fibrosis, edema, and congestion on resected specimens via histologic examination. RESULTS: The macroscopic adhesion score in group RM (7.27 ± 3.51) was significantly lower than those in groups C (13.36 ± 2.24) and R (11.71 ± 1.98); group M (9.13 ± 4.09) had a significantly lower adhesion score than group C. The number of remote adhesions was significantly lower in groups R and RM than in group C. The acute inflammation score, chronic inflammation score, and fibrosis score in group RM; the acute inflammation score in group R; and the fibrosis score in group M were significantly lower than those in group C. CONCLUSION: The intraperitoneal application of Mediclore and a combination of Mediclore and rosuvastatin effectively reduced postoperative adhesions.

ABSTRACT

(1) Background: The AJCC Cancer Staging Manual, Eighth Edition, subdivided T2 GBC into T2a and T2b. However, there still exist a lack of evidence on the prognostic significance of tumor location. The aim of the present study was to examine the existing evidence to determine the prognostic significance of tumor location of T2 gallbladder cancer (GBC) and to evaluate the optimal surgical extent according to tumor location. (2) Methods: We searched for relevant literature published in the electronic databases PubMed, MEDLINE, Web of Science, Cochrane Library, and Embase before September 2020 using search terms related to gallbladder, cancer, and stage. Data were weighted and pooled using random-effects modeling. (3) Results: Seven studies were deemed eligible for inclusion, representing a cohort of 1789 cases of resected T2 GBC. The overall survival for T2b tumor was significantly worse than that for T2a tumor (HR, 2.141; 95% confidence interval (CI), 1.140 to 4.023; I2 = 71.4%; Pchi2 = 0.007). The rate of lymph node metastasis was lower in the T2a group (26.6%) than in the T2b group (36.6%) (OR, 2.164; 95% CI, 1.309 to 3.575). There was no evidence of a survival difference between the patients who underwent extended cholecystectomy and simple cholecystectomy in T2a GBC (OR, 0.802; 95% CI, 0.618 to 1.042) and T2b GBC (OR, 0.820; 95% CI, 0.620 to 1.083). (4) Conclusions: Hepatic side tumor was a significant poor prognostic factor in T2 GBC. Extended cholecystectomy and simple cholecystectomy showed comparable survival outcomes in T2 GBC, and additional large-scale prospective studies are warranted to establish evidence-based treatment guidelines for T2 GBC.

ABSTRACT

Adequate nutritional support in critically ill patients is important, however, sometimes it has been neglected in perioperative period of patients at surgical intensive care units (SICU). The aim of this study was to investigate whether approaching target calorie intake of surgical patients influences on their clinical outcomes. A total of 279 patients who admitted at SICU in perioperative period from August 2014 to July 2016 at our hospital were analyzed. Demographics, supplied calorie amount and its method, lengths of SICU and hospital stay, and mortality of study population were collected. Among 279 patients, 103 patietns (36.9%) approached target calorie intake during SICU stay. Patients who approached target calorie intake had significantly decreased length of stay in SICU (10.78 ± 11.5 vs. 15.3 ± 9.9, p = 0.001) and hospital (54.52 ± 40.6 vs. 77.72±62.2, p < 0.001), than those did not, however there was no significant difference of mortality (9.7% vs. 8.5%, p = 0.829). Enteral feeding was a significant factor for target calorie achievement (odd ratio [OR], 2.029; 95% confidence interval [CI], 1.096-3.758; p = 0.024) and especially in patients with ≤ 7 days of SICU stay (OR, 4.13; 95% CI, 1.505-11.328; p = 0.006). Target calorie achievement in surgical patients improves clinical outcomes and enteral feeding, especially in early postoperative period would be an effective route of nutrition.

ABSTRACT

With the progression of acute cholecystitis, antimicrobial therapy becomes important for infection control. Current antibiotic recommendations were mostly based on reports of patients with acute cholangitis whose bile specimens were sampled from the biliary tract. However, as most infections of acute cholecystitis are limited to the gallbladder, direct sampling from the site increases the probability of identifying the causative pathogen. We investigated 321 positive bile cultures from 931 patients with acute cholecystitis who underwent laparoscopic cholecystectomy between January 2003 and December 2017. The frequency of enterococci declined (P = 0.041), whereas that of Enterobacteriales (P = 0.005), particularly Escherichia (P = 0.008), increased over time. The incidence of ciprofloxacin-resistant Enterobacteriales showed a significant increasing trend (P = 0.031). Vancomycin-resistant E.faecium, carbapenem-resistant Enterobacteriales, and extended-spectrum beta-lactamase-producing Enterobacteriales were recently observed. In grade I and II acute cholecystitis, there were no significant differences in perioperative outcomes in patients with and without early appropriate antimicrobial therapy. In conclusion, the changing incidence of frequently isolated microorganisms and their antibiotic resistance over time would be considered before selecting antibiotics for the treatment of acute cholecystitis. Surgery might be a crucial component of infection control in grade I and II acute cholecystitis.

ABSTRACT

Background: Treatment of biliary infection in liver transplant (LT) recipients is a challenge, especially because of ineffectiveness of the antibiotic agents otherwise recommended for non-transplant populations. We aimed to understand the factors underlying the choice of antibiotic therapy. Patients and Methods: A total of 373 bile cultures from LT recipients with biliary complications (n = 127; LT group) and from a non-transplant population that underwent cholecystectomy for acute cholecystitis (n = 246; non-transplant group) between January 2009 and December 2018, were investigated. Results: Polymicrobial cultures (13.4% vs. 1.6%; p < 0.001), Enterococcus faecium (26.0% vs. 8.5%; p < 0.001), and Pseudomonas (13.4% vs. 4.1%; p = 0.001) in the LT group, and non-faecium enterococci (3.9% vs. 18.3%; p < 0.001) and Enterobacteriales (40.2% vs. 54.9%; p = 0.007), especially Escherichia (11.0% vs. 29.7%; p < 0.001), in the non-transplant group, showed higher abundance. Most of the antibiotic agents recommended as initial antibiotic therapy for the non-transplant population as per previous guidelines were not effective in LT recipients. The incidences of Enterococcus faecium (14.9% vs. 32.5%; p = 0.029) in the LT recipients with model for end-stage liver disease (MELD) score >12 and non-faecium enterococci (8.5% vs. 1.3%; p = 0.042) in those with MELD score ≤12 were higher than those in the other group. The incidence of Enterobacteriales increased over time after LT (p = 0.048) and was similar to that in the non-transplant group after one year of LT. Bile micro-organisms in LT recipients, resistant to most antibiotic agents, especially soon after LT changed over time and became similar to those in the non-transplant group after one year of LT. Conclusions: Antibiotic therapy for biliary infection in LT recipients should be different from that in non-transplant populations, considering clinical factors such as the time interval after LT and MELD score.

ABSTRACT

BACKGROUND: T2 gallbladder cancer (GBC) is subdivided into T2a and T2b by the American Joint Committee on Cancer (AJCC) 8th edition. However; there is a lack of evidence for the prognostic significance of tumor location and validation with large-scale studies is needed. The aims of this study were to investigate the clinical features and clinical outcomes of T2 GBC according to tumor location and determine the prognostic significance of tumor location and an appropriate surgical strategy. METHODS: Between 2000 and 2014 the Korea Tumor Registry System Biliary Pancreas (KOTUS-BP) database was used to identify and enroll a total 707 patients with pathologically diagnosed T2 GBC who underwent curative resection. Clinicopathological findings and long-term follow-up results were analyzed. RESULTS: The incidence of lymph node metastasis in T2b was significantly higher than that of T2a tumors (37.9% vs. 29.5%, p = 0.032). The 5-year disease-specific survival of T2a was better than that of T2b tumors (74.8% vs. 65.4%, p = 0.019). There was no significant survival difference in T2a between extended cholecystectomy and simple cholecystectomy with lymph node dissection (81.8% vs. 73.7%, p = 0.361). However; there was a better survival trend for T2b tumor after extended cholecystectomy (71.7% vs. 59.3%, p = 0.057). Adjuvant chemotherapy was associated with improved survival for patients with lymph node metastasis in T2a (72.1% vs. 56.9; p = 0.022) and in T2b (68.2 vs. 48.5; p < 0.001). Multivariate analysis revealed that lymph node metastasis was the only significant poor prognostic factor (Hazard ratio 3.222; 95% confidential interval 1.960-4.489; p < 0.001). CONCLUSIONS: For T2 GBC; tumor location was not an independent prognostic factor. Lymph node metastasis was a significant poor prognostic factor and adjuvant chemotherapy should be considered for the patients with lymph node metastasis.

ABSTRACT

Several studies have reported short-term results for post-cholecystectomy symptoms and quality of life (QoL). However, reports on long-term results are still limited. This study aimed to identify risk factors affecting short- and long-term patient-reported outcome (PRO) following laparoscopic cholecystectomy.From 2016 to 2017, a total of 476 patients from 5 institutions were enrolled. PRO was examined using the Numeric Rating Scale (NRS) pain score and the Gastrointestinal (GI) QoL Index questionnaire at postoperative 1 month and 1 year.Most of patients recovered well at postoperative 1 year compared to postoperative 1 month for the NRS pain score, QoL score, and GI symptoms. A high operative difficulty score (HR 1.740, P = .031) and pathology of acute or complicated cholecystitis (HR 1.524, P = .048) were identified as independent risk factors for high NRS pain scores at postoperative 1 month. Similarly, female sex (HR 1.571, P = .003) at postoperative 1 month and postoperative complications (HR 5.567, P = .001) at postoperative 1 year were independent risk factors for a low QoL. Also, age above 50 (HR 1.842, P = .001), female sex (HR 1.531, P = .006), and preoperative gallbladder drainage (HR 3.086, P = .001) were identified as independent risk factors for GI symptoms at postoperative 1 month.Most patients showed improved long-term PRO measurement in terms of pain, QoL, and GI symptoms. There were no independent risk factors for long-term postoperative pain and GI symptoms. However, postoperative complications were identified to affect QoL adversely at postoperative 1 year. Careful and long-term follow up is thus necessary for patients who experienced postoperative complications.

ABSTRACT

Laparoscopic appendectomy (LA) is perceived as a procedure requiring a short hospital stay; however, some patients require prolonged hospitalization because of postoperative ileus and pain; therefore, we introduced clipless LA, using only an ultrasonic energy device only for coagulation. A total of 1013 patients (clipless LA; n=290 and conventional LA; n=723) who underwent LA at our hospital between January 2015 and February 2018 were analyzed. The mean operative time was shorter (P<0.001), and postoperative pain score at 24 hours was lower (P<0.001) for clipless than for conventional LA. There were no significant differences in postoperative complications, except with regard to early postoperative ileus (clipless LA; 18.1% vs. conventional LA; 31.6%, P=0.025), and the operative method had significantly influenced early postoperative ileus (relative risk, 0.505; 95% confidence interval, 0.257-0.994; P=0.048). Clipless LA is comparable to conventional LA with regard to operative safety but results in significantly less pain and postoperative ileus.

ABSTRACT

BACKGROUND: Despite the incremental application of single-incision laparoscopic cholecystectomy (SILC), this procedure has technical difficulties, including physical disturbance and an unstable surgical view through the small incision; therefore, we introduce the solo SILC (S-SILC) technique using a laparoscopic scope holder, as a simple, fixed and easy-to-perform procedure for an unassisted surgeon. METHODS: We performed a comparative analysis of S-SILC (n = 566) and conventional three-incision laparoscopic cholecystectomy (n = 874) performed from January 2013 to December 2016 at multiple centres. RESULTS: There was no significant difference of operative time between the two groups (P = 0.176); however, S-SILC showed a higher incidence of intraoperative gallbladder perforation, especially in the initial period (17.0% versus 2.3%, P < 0.001); and shorter post-operative hospital stay (3.3 ± 1.7 versus 1.9 ± 2.7 days, P < 0.001) than conventional three-incision laparoscopic cholecystectomy. There were no significant differences in major post-operative complications between the two groups (P = 0.909) and operation type (P = 0.971) was not a significant risk factor for major post-operative complications in multivariate analysis. CONCLUSION: S-SILC is a feasible and safe procedure; however, careful selection of surgical candidates is necessary in the early period of the experience with this method.

ABSTRACT

INTRODUCTION: Single-port laparoscopic appendectomy (SPLA) was expected to have reduced risk of wound infection, less postoperative pain, and improved patient's satisfaction with better cosmesis compared with conventional laparoscopic appendectomy (CLA). When SPLA is converted to CLA, the additional incision for another port insertion can lead to a decrease in the surgical advantages and clinical benefit. AIM: To evaluate risk factors for conversion to CLA during SPLA. MATERIAL AND METHODS: Between August 2015 and December 2016, patients who underwent intended SPLA were retrospectively reviewed. Conversion was defined as any insertion of an additional port, and complicated appendicitis was defined as gangrenous or perforated appendicitis, abscess, or peritonitis in preoperative computed tomography. Postoperative complication was defined as any deviation in the routine postoperative course within 30 days postoperatively. RESULTS: Of 409 patients, 65 (15.9%) were treated with additional port insertion. The overall complication rate was 1.5% in each group, of which 1 patient developed superficial SSI and 4 patients developed deep surgical site infections in the SPLA group. After univariable and multivariable analysis, old age, male sex, increased serum C-reactive protein (OR = 2.944; 95% CI: 1.433-6.047; p = 0.003), and complicated appendicitis (OR = 3.330; 95% CI: 1.304-8.503; p = 0.012) were significant risk factors for conversion to CLA. CONCLUSIONS: The conversion rate to CLA was 15.9%. Serum C-reactive protein level and complicated appendicitis were strong predictive factors for conversion from SPLA in acute appendicitis.

ABSTRACT

Background. Technical difficulties and pain from large wounds have prevented the widespread use of single-incision laparoscopic appendectomy (SILA). This study aimed to evaluate the efficacy of our newly developed needle grasper (Endo Relief)-assisted SILA (NASILA). Methods. For NASILA, about a 12-mm umbilical incision was made, and a glove port was introduced. A needle grasper was then introduced through a 2.5-mm wound on the suprapubic area. For SILA, a 2.5-cm transumbilical wound was made. The medical records of patients who underwent SILA or NASILA from June 2017 to September 2017 were retrospectively reviewed. Operative and short-term postoperative outcomes and results of telephone interviews for scars were compared. Results. A total of 49 patients in the SILA group (male: 40.8%) and 12 in the NASILA group (male: 50.0%) were included. Appendicitis status (not perforated:perforated without abscess:perforated with abscess) was significantly different between the 2 groups (SILA vs NASILA, 30:18:1 vs 4:6:2, P = .027). Additional trocars were inserted in 9 patients (18.4%) of the SILA group. The operative time was significantly shorter (43.3 ± 33.6 vs 54.1 ± 15.6 minutes, P = .012), and the highest numerical pain intensity score during the first 24 hours after surgery was significantly lower (2.4 ± 0.7 vs 3.0 ± 0.9, P = .038) in the NASILA group than in the SILA group. Hospital stay, postoperative complications, and complaint of scar were not significantly different between the 2 groups. Conclusions. NASILA was not inferior to SILA regarding cosmetic results. Operative convenience is higher in NASILA than in SILA, and the smaller surgical wound in NASILA minimizes postoperative pain.

ABSTRACT

BACKGROUND: Surgical resection (SR) is recommended for single hepatocellular carcinoma (HCC) in patients with well-preserved liver function. However, unexpected liver fibrosis sometimes found at the SR which leads to a poor outcome. This study investigated the influence of liver fibrosis on prognosis after SR for HCC. METHODS: A total of 189 patients with Child-Turcotte-Pugh grade A who underwent curative SR for a single HCC <5 cm were evaluated. Patients were assigned to two groups based on the degree of fibrosis (mild or severe), as determined by histological evaluation. RESULTS: Severe fibrosis was present in 49 patients (25.9%); these patients had greater posthepatectomy liver failure (P = 0.000) and HCC recurrence (P = 0.016). Severe liver fibrosis (hazard ratio (HR) = 1.849, 95% confidence interval (CI) 1.191-2.869; P = 0.006), microvascular invasion (HR = 1.854, 95% CI 1.183-2.906; P = 0.007), and poor histologic grade (HR = 2.097, 95% CI 1.230-3.574; P = 0.007) were related to HCC recurrence. CONCLUSION: Severe fibrosis can be found even in patients with well-preserved liver function and it leads to poorer early post-operative and late oncologic outcomes, therefore it should be considered before therapeutic decision making of HCC.

ABSTRACT

PURPOSE: Postcholecystectomy syndrome (PCS) is characterized by abdominal symptoms following gallbladder removal. However, there is no consensus for the definition or treatment for PCS. The purpose of this study was to define PCS among various symptoms after laparoscopic cholecystectomy, and to identify risk factors affecting PCS. METHODS: This study was conducted at Dongguk University Ilsan Hospital and Chung-Ang University Hospital (2012-2013). Outcomes were assessed using European Organization for Research and Treatment of Cancer QLQ-C30 questionnaire. Symptom cluster for determining PCS was made by factor analysis. Cluster analysis evaluating risk factors of PCS was made by Ward methods and Dentogram. RESULTS: Factor analysis revealed three distinct symptom clusters, those are 'insomnia and financial difficulties (eigenvalue, 1.707; Cronbach α, 0.190),' 'appetite loss and constipation (eigenvalue, 1.413; Cronbach α, 0.480),' and 'right upper quadrant (RUQ) pain and diarrhea (eigenvalue, 1.245; Cronbach α, 0.315).' Among these symptom clusters, the cluster of 'RUQ pain and diarrhea' was determined as PCS. However, we could not find any risk factors between high symptomatic group and low symptomatic group. CONCLUSION: PCS could consist of RUQ pain and diarrhea. Well-designed prospective trials are needed to determine risk factors of PCS.
