RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Purpose@#The aim of this study was to evaluate the safety and feasibility of applying enhanced recovery after surgery (ERAS) protocol in elderly colorectal cancer patients. @*Methods@#The medical records of patients who underwent elective colorectal cancer surgery at our institution, from January 2017 to December 2017, were reviewed. Patients were divided into 2 groups: the young group (YG, patients aged 70 and under 70 years) and the old group (OG, patients over 70 years old). Perioperative outcomes and length of hospital stay were compared between both groups. @*Results@#In total, 335 patients were enrolled; 237 were YG and 98 were OG. Despite the poorer baseline characteristics of OG, the perioperative outcomes were similar. Length of hospital stay was not different between the groups (YG, 5 days vs. OG, 5 days; P=0.320). When comparing the postoperative complications using the comprehensive complication index (CCI), there was no significant difference (YG, 8.0±13.2 vs. OG, 11.7±23.0; P=0.130). In regression analysis, old age (>70 years) was not a risk factor for high CCI in all patients. In multivariate analysis, C-reactive protein (CRP) level on postoperative day (POD) 3 to 4 was the only strong predictive factor for high CCI in elderly patients. @*Conclusion@#Implementing the ERAS protocol in patients aged >70 years is safe and feasible. High CRP (≥6.47 mg/dL) on POD 3 to 4 can be used as a safety index to postpone discharge in elderly patients.

RESUMO

Purpose@#Intrathecal analgesia (ITA) and transverse abdominis plane block (TAPB) are effective pain control methods in abdominal surgery. However, there is still no gold standard for postoperative pain control in minimally invasive colorectal surgery. This study aimed to investigate whether the analgesic effect could be increased when TAPB, which can further reduce wound somatic pain, was administered in low-dose morphine ITA patients. @*Methods@#Patients undergoing elective colorectal surgery were randomized into an ITA with TAPB group or an ITA group. Patients were evaluated for pain 0, 8, 16, 24, and 48 hours after surgery. The primary outcome was the total morphine milligram equivalents administered 24 hours after surgery. The secondary outcomes were pain scores, ambulatory variables, inflammation markers, hospital stay duration, and complications within 48 hours after surgery. @*Results@#A total of 64 patients were recruited, and 55 were compared. There was no significant difference in morphine use over the 24 hours after surgery in the 2 groups (ITA with TAPB, 15.3 mg vs. ITA, 10.2 mg; P = 0.270). Also, there was no significant difference in pain scores. In both groups, the average pain score at 24 and 48 hours was 2 points or less, showing effective pain control. @*Conclusion@#ITA for pain control in patients with colorectal surgery is an effective pain method, and additional TAPB was not effective.

RESUMO

Purpose@#This study was performed to evaluate complications using comprehensive complication index (CCI) in colorectal cancer patients with implementation of the Enhanced Recovery After Surgery (ERAS) protocol, and to investigate the predictive factors associated with high morbidity rates. It can be used as a safety net in determining the timing of discharge. @*Methods@#A total of 335 consecutive patients who underwent elective colorectal cancer surgery between January 2017 and December 2017 at a single tertiary center were enrolled. Postoperative complications were defined as occurring within 30 days after surgery. The predictive factor analysis for the high CCI group was also performed. @*Results@#In total, 116 patients experienced postoperative complications. Wound-related complications and postoperative ileus were the most common. The mean CCI for overall colorectal cancer surgery was 9.1 ± 16.7. Patients featuring low CCI (<26.2) were 297 (88.7%) and high CCI were 38 (11.3%). In multivariable analysis, obstructive colorectal cancer (odds ratio, 3.278; 95% confidence interval, 1.217–8.829; P = 0.019) and CRP value on postoperative day (POD) 3–4 (odds ratio, 1.152; 95% confidence interval, 1.036–1.280; P < 0.010) were significant predictors for high CCI. @*Conclusion@#The clinical usefulness of CCI in colorectal cancer patients with the ERAS protocol was verified, and it can be used for surgical quality control. More cautious care is needed and the timing of discharge should be carefully determined for patients with obstructive colorectal cancer or POD 3–4 CRP of ≥6.47 mg/dL.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Purpose@#Few studies have analyzed the effects of preoperative pain education on the postoperative decision to discharge. The purpose of this study was to determine the effects of pain education and management on the decision to discharge patients after single-incision laparoscopic appendectomy (SILA). @*Methods@#We analyzed 135 patients who had undergone SILA for acute appendicitis between March 2017 and April 2018 in a single medical center. Of these, 72 patients (53.3%) had received preoperative pain education (group 1), and 63 (46.7%) had not (group 2). We compared perioperative outcomes and complications between the groups. @*Results@#Baseline characteristics of sex, age, body mass index, American Society of Anesthesiologist score, and systemic inflammation factors (neutrophil-lymphocyte ratio, C-reactive protein level) did not differ significantly between the groups. There were no postoperative complications for patients in either group. Perioperative consequences and pathologic findings were not significantly different between the groups; however, length of hospital was significantly shorter in group 1. @*Conclusion@#Preoperative pain education in relation to postoperative pain management influenced the decision to shorten the postoperative hospital length of stay after SILA.

RESUMO

Purpose@#Minimally invasive colorectal surgery had reduced the rate of surgical site infection. The use of surgical skin adhesive bond (2-octyl cyanoacrylate) for wound closure reduces postoperative pain and provides better cosmetic effect compared to conventional sutures or staples. But role of surgical skin adhesive bond for reducing surgical site infection is unclear. Our objective in this study was to evaluate the role of surgical skin adhesive bond in reducing surgical site infection following minimally invasive colorectal surgery. @*Methods@#We performed a retrospective analysis of 492 patients treated using minimally invasive surgery for colorectal cancer at Seoul St. Mary’s Hospital, the Catholic University of Korea. Of these, surgical skin adhesive bond was used for wound closure in 284 cases and skin stapling in 208. The rate of surgical site infection including deep or organ/space level infections was compared between the 2 groups. @*Results@#The rate of superficial surgical site infection was significantly lower in the group using skin adhesive (p = 0.024), and total costs for wound care were significantly lower in the skin adhesive group (p < 0.001). @*Conclusion@#This study showed that surgical skin adhesive bond reduced surgical site infection and total cost for wound care following minimally invasive colorectal cancer surgery compared to conventional skin stapler technique. Surgical skin adhesive bond is a safe and feasible alternative surgical wound closure technique following minimally invasive colorectal cancer surgery.

RESUMO

PURPOSE: We conducted a multi-institutional analysis to establish the epidemiological characteristics of recurrent inguinal hernia following hernia repair in patients across 4 institutions in Korea.METHODS: The retrospectively reviewed data included patient characteristics, hernia location, year of primary operation, type of hernia, timing of recurrence, primary operation type, and whether a mesh was used.RESULTS: Among 4,604 patients who underwent hernia repair surgery, 255 patients (5.5%; 13 females and 242 males; mean age, 63 years) were found to have recurrent hernia from January 2010 to April 2017. Recurrent indirect inguinal and direct hernias were observed in 47.1% and 49.4% of the patients, respectively. The recurrence of hernias within 1 year of surgery was the highest at 17.25%. Early and late recurrences was observed in 23.5% and 66.5% of the patients, respectively. Among the patients, 81.6% underwent open hernia repair at the time of initial surgery.CONCLUSION: Recurrence of hernia is most common in the first year after the initial surgery, and 23.5% of recurrent inguinal hernia was developed within 2 years. Patients underwent surgery after an average of 116 months (median value, 64 months) following the first operation. In patients with recurrent hernia, direct hernia was seen more frequent than indirect hernia whereas indirect hernia occurred more in patients with primary hernia.

RESUMO

BACKGROUND/AIMS: Computed tomography (CT) hepatic volumetry is currently accepted as the most reliable method for preoperative estimation of graft weight in living donor liver transplantation (LDLT). However, several factors can cause inaccuracies in CT volumetry compared to real graft weight. The purpose of this study was to determine the frequency and degree of resection plane-dependent error in CT volumetry of the right hepatic lobe in LDLT. METHODS: Forty-six living liver donors underwent CT before donor surgery and on postoperative day 7. Prospective CT volumetry (VP) was measured via the assumptive hepatectomy plane. Retrospective liver volume (VR) was measured using the actual plane by comparing preoperative and postoperative CT. Compared with intraoperatively measured weight (W), errors in percentage (%) VP and VR were evaluated. Plane-dependent error in VP was defined as the absolute difference between VP and VR. % plane-dependent error was defined as follows: |VP–VR|/W∙100. RESULTS: Mean VP, VR, and W were 761.9 mL, 755.0 mL, and 696.9 g. Mean and % errors in VP were 73.3 mL and 10.7%. Mean error and % error in VR were 64.4 mL and 9.3%. Mean plane-dependent error in VP was 32.4 mL. Mean % plane-dependent error was 4.7%. Plane-dependent error in VP exceeded 10% of W in approximately 10% of the subjects in our study. CONCLUSIONS: There was approximately 5% plane-dependent error in liver VP on CT volumetry. Plane-dependent error in VP exceeded 10% of W in approximately 10% of LDLT donors in our study. This error should be considered, especially when CT volumetry is performed by a less experienced operator who is not well acquainted with the donor hepatectomy plane.

RESUMO

BACKGROUND/AIMS: Hepatitis B viral protein X (HBx) is implicated in the pathogenesis of hepatocellular carcinoma (HCC) as well as the elevation of heat shock proteins (HSPs) after hepatitis B virus (HBV) infection. We thus investigated the anticancer effects of an HSP90 inhibitor 17-Dimethylaminoethylamino-17-demethoxygeldanamycin (17-DMAG) in HBx-transfected hepatocellular carcinoma cells. METHODS: pcDNA-HBx was made by inserting the HBx gene derived from the HBV-infected patient into pcDNA3.1 using the restriction enzymes (XbaI/HindIII). HBx-expressing HepG2 cells were then generated by transfecting HepG2 cells with pcDNA containing HBx gene. To compare the anticancer effects of 17-DMAG between pcDNA-HBx transfected HepG2 cells and the control cells (pcDNA-transfected HepG2 cells), we performed various molecular studies, including Ez-cytox proliferation assay, Western blot analysis, and flow cytometry. RESULTS: 17-DMAG inhibited the proliferation of pcDNA-HBx transfected HepG2 cells better than control cells (P<0.05). After treating with a various concentration of 17-DMAG (50–1,000 nM), pcDNA-HBx transfected HepG2 cells exhibited higher expression of pro-apoptotic proteins (c-caspase-3, c-caspase-8, and c-caspase-9) than did control cells (P<0.05). pcDNA-HBx transfected HepG2 cells showed higher activities of caspase-3, caspase-8, and caspase-9 than did control cells (P<0.05). Finally, we found that the expression of pro-apoptotic proteins (PARP and c-caspase-3) was considerably decreased by the use of a caspase inhibitor suggesting that 17-DMAG induces the cell death of HepG2 cells caspase-dependently. CONCLUSIONS: Our study strongly suggests that 17-DMAG has antiviral effects against HBV as well as anticancer effects against HepG2 cells. Thus, the application of 17-DMAG appears to be particularly advantageous to the HCC patients related with HBV infection.

RESUMO

The most frequent perioperative cardiovascular event is cardiac dysrhythmia, defined as an abnormality of cardiac rate, rhythm or conduction. Although the occurrence of arrhythmia during the perioperative period is not uncommon, a case of newly developed perioperative atrial flutter which spontaneously converts to atrial fibrillation is rare. We report a case of atrial flutter that developed immediately after induction of general anesthesia, in a 70-year-old male patient who previously had a normal sinus rhythm. Atrial flutter changed spontaneously to atrial fibrillation after discharge to the recovery room. Dysrhythmia was unresponsive to drug therapy, and the atrial fibrillation disappeared after electric cardioversion.

RESUMO

Ceftriaxone is a commonly used antibiotic due to some of its advantages. Reversible gallbladder (GB) sludge or stone has been reported after ceftriaxone therapy. Most of these patients have no symptom, but the GB sludge or stone can sometimes cause cholecystitis. We experienced two patients who had newly developed GB stones after ceftriaxone therapy for diverticulitis and pneumonia, and this resolved spontaneously 1 month after discontinuation of the drug. Awareness of this complication could help to prevent unnecessary cholecystectomy.
