RESUMO
BACKGROUND: There are few available studies that compare the feasibility, efficacy, and safety of robotic pelvic lateral lymph node dissection compared to laparoscopic pelvic lateral lymph node dissection (LPLND) in advanced rectal cancer. This meta-analysis aims to compare perioperative outcomes between robotic and LPLND. METHODS: We performed a systemic literature review of PubMed, Embase, and Web of Science databases. Perioperative parameters were extracted and pooled for analysis. This meta-analysis provided an analysis of heterogeneity and prediction intervals. RESULTS: Five studies were included: 567 patients divided between 266 robotic and 301 LPLND. Overall operation time was longer in the robotic group than laparoscopic group (difference in means = 67.11, 95% CI [30.80, 103.42], p < 0.001) but the difference in the pelvic lateral lymph dissection time was not statistically significant (difference in means = - 1.212, 95% CI [ - 11.594, 9.171], p = 0.819). There were fewer overall complications in the robotic than in the laparoscopic group (OR = 1.589, 95% CI [1.009, 2.503], p = 0.046), especially with respect to urinary retention (OR = 2.23, 95% CI [1.277, 3.894], p = 0.005). More pelvic lateral lymph nodes were harvested by robotic surgery than by laparoscopy (differences in means = - 1.992, 95% CI [ - 2.421, 1.563], p < 0.001). CONCLUSIONS: In this meta-analysis, robotic pelvic lateral lymph node dissection was associated with more pelvic lateral lymph nodes harvested and lower overall complications, especially urinary retention when compared to LPLND. Further studies are needed to reinforce these findings.

BACKGROUND/PURPOSE: Limited studies have addressed the exacerbation of symptoms and long COVID in inflammatory bowel disease (IBD) patients following non-severe COVID-19 infection, particularly with post-COVID-19 vaccination. We aim to investigate factors associated with exacerbated gastrointestinal symptoms (EGS) and long COVID in IBD patients with non-severe COVID-19, which is most common situation in daily practice. METHODS: This is an observational study by multiple centers in Taiwan from May 2020 to March 2023. We collected clinical manifestation, data, and medication information from IBD patients with non-severe COVID-19. EGS was defined as increased frequency of diarrhea, bloody stool, and abdomen pain within 14 days after SARS-COV-2 infection. Long COVID was defined following the guidelines of the World Health Organization. RESULTS: Out of 90 patients, most of them (88.9%) received at least standard two doses of COVID-19 vaccination and the majority (87.8%) were mild diseases of COVID-19.30% of patients experienced EGS during COVID-19 with higher ESR levels serving as a predictive factor (Odds ratio: 3.6, 95% confidence interval: 1.2-10.5, P = 0.02). 38.1% of those patients developed long COVID. The patients who experienced EGS during COVID-19 and with a history of longer IBD duration showed a significant association with long COVID (p = 0.03 and p = 0.02). CONCLUSION: Our study revealed that EGS and long COVID occurred in one third of IBD patients with non-severe COVID-19, even though most of them had received the standard plus booster vaccination. We identified associated factors for EGS and long COVID, emphasizing the importance of post-COVID-19 follow-up in IBD patients.

BACKGROUND/AIM: The effect of pelvic neoadjuvant radiotherapy (nRT) for stage M1a rectal adenocarcinoma patients treated with systemic therapy followed by proctectomy and metastasectomy was scarcely investigated in the literatures. PATIENTS AND METHODS: The eligible rectal cancer patients diagnosed between 2011-2019 were identified via the Taiwan Cancer Registry. In the primary analysis, we used propensity score weighting to balance observable potential confounders and compared the hazard ratio (HR) of death for the nRT group vs. without RT group. We also compared the incidence of rectal cancer mortality (IRCM) and performed various supplementary analyses. RESULTS: Our primary analyses included 145 patients. nRT was associated with improved OS (HR=0.51, p=0.01). The numerical trends remained similar for IRCM and in supplementary analyses. CONCLUSION: nRT was associated with improved OS in our study population.

Crohn's disease (CD) is a chronic inflammatory disease mainly affecting the gastrointestinal tract. With the increased availability of modalities in the last two decades, the treatment of CD has advanced remarkably. Although medical treatment is the mainstay of therapy, most patients require surgery during the course of their illness, especially those who experience complications. Nutritional optimization and ERAS implementation are crucial for patients with CD who require surgical intervention to reduce postoperative complications. The increased surgical risk was found to be associated with the use of corticosteroids, but the association of surgical risk with immunomodulators, biologic therapy, such as anti-TNF mediations, anti-integrin medications, and anti-IL 12/23 was low in certainty. Decisions about preoperative medication must be made on an individual case-dependent basis. Preoperative imaging studies can assist in the planning of appropriate surgical strategies and approaches. However, patients must be informed of any alterations to their treatment. In summary, the management of perioperative medications and surgery-related decision-making should be individualized and patient-centered based on a multidisciplinary approach.
RESUMO
INTRODUCTION: Laparoscopic colectomy is rarely performed for ischemic colitis. The aim of this propensity score-matched study was to compare preoperative characteristics, intraoperative details and short-term outcomes for emergent laparoscopic colectomy versus the traditional open approach for patients with ischemic colitis. METHODS: Retrospective review of 96 patients who underwent emergent colectomy for ischemic colitis between January 2011 and December 2020 (39 via laparoscopy, 57 via laparotomy) was performed. We compared short-term outcomes after using a one-to-one ratio and nearest-neighbor propensity score matching to obtain similar preoperative and intraoperative parameters in each group. RESULTS: Patients in the open group experienced more surgical site complications (52.6% vs. 23.0%, p = 0.004), more intra-abdominal abscesses (47.3% vs. 17.9%, p = 0.003), longer need for ventilator support (20 days vs. 0 days, p < 0.001), more major complications (77.2% vs. 43.5%, p = 0.001), higher mortality (49.1% vs. 20.5%, p = 0.004), and longer hospital stay (32 days vs. 19 days, p = 0.001). After propensity score matching (31 patients in each group), patients undergoing open (vs. laparoscopy) had more surgical site complications (45.1% vs. 19.4%, p = 0.030) and required longer ventilator support (14 vs. 3 days, p = 0.039). After multivariate analysis, Charlson Comorbidity Index (p = 0.024), APACHE II score (p = 0.001), and Favier's classification (p = 0.023) were independent predictors of mortality. CONCLUSIONS: Laparoscopic emergent colectomy for ischemic colitis is feasible and is associated with fewer surgical site complications and better respiratory function, compared to the open approach.

BACKGROUND: Peritoneal contamination is a major concern during natural orifice specimen extraction after laparoscopic colorectal resection (LCR-NOSE), but few data are available. We explored the prevalence, risk factors, and association between clinical outcomes and infectious complications in patients with positive peritoneal drain fluid culture (PDFC) after LCR-NOSE. METHOD: We retrospectively analyzed patient records in our prospectively maintained registry database who underwent LCR-NOSE between 2011and 2020. Peritoneal drain fluid was collected within 12 h post-operative and cultures for microorganisms were obtained. The relationships between PDFC, clinical variables, and infectious complications were examined by univariate and multivariable analysis. RESULTS: Of 241 consecutive patients who underwent LCR-NOSE and drainage fluid culture, 59 (24.5%) had PDFC. Anterior resection (Odds ratio OR 2.40) was identified as an independent predictor for PDFC. Twenty-eight patients (11.6%) developed infectious complications. Multivariable analysis identified low anterior resection (OR 2.74), prolonged operative time (OR 3.20), and PDFC (OR 5.14) as independent risk factors. Pseudomonas aeruginosa was the most frequently found microorganism (OR 5.19) responsible for infectious complications. CONCLUSIONS: Microorganisms are commonly present in the peritoneum after LCR-NOSE and play a critical role in the development of infectious complications and related morbidity. Specific caution is warranted in patients contaminated with specific types of microorganisms.

BACKGROUND: There is still no consensus on the management of intraperitoneal anastomotic leakage after colonic surgery. Among of various treatment strategies, laparoscopic redo anastomosis for intraperitoneal leakage has rarely been reported in the literature and is condemned by some. The aim of this study is to demonstrate the feasibility and safety of laparoscopic redo anastomosis for intraperitoneal anastomotic leakage. METHODS: Retrospective chart review of laparoscopic redo anastomosis for intraperitoneal anastomotic leakage after colonic surgery from January 2013 to May 2020. An accompanying video demonstrates the technique. RESULTS: Fifteen consecutive patients underwent laparoscopic redo anastomosis for management of leakage after colonic surgery; two patients required conversion to open repair. A protective stoma was created in three patients during the second operation. There was no re-leakage nor mortality in this series. CONCLUSIONS: Laparoscopic redo anastomosis was feasible and safe for the management of intraperitoneal anastomotic leakage after colonic surgery. Considering the advantages of re-do laparoscopy, this procedure should be part of every surgeon's armamentarium to deal with anastomotic leakage and represents a logical alternative to the "Diversion and Drainage" technique.

INTRODUCTION: No universal consensus exists on the management of intraperitoneal anastomosis leakage after colonic surgery. The aim of the study was to evaluate the outcomes of laparoscopic reintervention without stoma creation for intraperitoneal leaks after colonic surgery. MATERIAL AND METHODS: Single tertiary center study conducted from January 2010 to December 2020. 54 patients with intraperitoneal leakage were divided into 2 groups according to whether they received a stoma (n = 37) or not (n = 17) during laparoscopic reintervention. Short term outcome was analyzed. RESULTS: Patients in the no stoma group had lower American Society of Anesthesiologists (ASA) score (P = .009), lower Acute Physiology And Chronic Health Evaluation II (APACHE II) score (5 vs. 10; P < .001) compared with the stoma group. Intensive care unit admission (43.2% vs. 5.8%; P = .006) and major complications (35.1% vs. 5.8%; P = .015) occurred more in the stoma group compared to the no stoma group. After multivariate logistic regression analysis, initial surgical procedure (P = .001) and APACHE II score (P = .039) were significant predictors of no stoma. The APACHE II score(P = .035) was an independent predictor of major complications. Finally, Receiver Operating Characteristic curve analysis showed that the cutoff value of APACHE II score for no stoma was 7.5. CONCLUSIONS: In our study, APACHE II score was an independent predictor of stoma formation and the cutoff value of APACHE II score for no stoma was 7.5. Our results need to be confirmed by larger and randomized studies. In particular, a specific APACHE II threshold to omit a stoma in this setting remains to be determined.

BACKGROUND: There is still no consensus on the management of colorectal anastomotic leakage after low anterior resection. The goal was to evaluate the outcomes of patients who underwent transanal endoluminal repair + laparoscopic drainage ± stoma vs. drainage only ± stoma. METHODS: Retrospective chart review of patients sustaining anastomotic leakage after laparoscopic low anterior resection between January 2013 and September 2020 who required laparoscopic reoperation. RESULTS: Forty-nine patients were included, 22 patients underwent combined laparoscopy and transanal endoluminal repair and 27 patients had drainage with a stoma (n = 16) or drainage alone (n = 11), without direct anastomotic repair. The overall morbidity rate was 30.6% and the mortality rate was 2%. Combined laparoscopic lavage/drainage and transanal endoluminal repair of anastomotic leakage was associated with a lower complication rate (13.6% vs. 44.4%, p = 0.03) and fewer intraabdominal infections (4.5% vs. 29.6%, p = 0.03) compared with no repair. CONCLUSIONS: Combined laparoscopic lavage/drainage and transanal endoluminal repair is effective in the management of colorectal anastomosis leakage and was associated with lower morbidity-in particular intraabdominal infection-compared with no repair. However, our results need to be confirmed in larger, and ideally randomized, studies.

BACKGROUND: Although reduced port laparoscopic surgery (RPLS), defined as laparoscopic surgery performed with the minimum possible number of ports and/or small-sized ports, is less invasive than conventional laparoscopic surgery by reducing the number of surgical wounds, an extension of the incision is still needed for specimen extraction, which can undermine the merits of RPLS. OBJECTIVE: To determine the impact of natural orifice specimen extraction (NOSE) in patients undergoing RPLS for colorectal cancer. The endpoints were perioperative outcome and oncologic safety at 3 years. SETTING: Single-center experience (2013-2019). PATIENTS: We retrospectively analyzed our prospectively collected patient records (American Joint Committee on Cancer (AJCC) stage I-III sigmoid or upper rectal cancer (tumor diameter ≤ 5 cm) who underwent curative anterior resection via RPLS. We excluded patients who did not undergo intestinal anastomosis. INTERVENTIONS: Perioperative and oncologic outcomes were compared between patients undergoing natural orifice (RPLS-NOSE) or conventional (mini-laparotomy) specimen extraction (RPLS-CSE). Patients were matched by propensity scores 1:1 for tumor diameter, AJCC stage, American Society of Anesthesiologists score and tumor location. RESULTS: Of 119 eligible patients, 104 were matched (52 RPLS-NOSE; 52 RPLS-CSE) by propensity scores. Compared with RPLS-CSE, RPLS-NOSE was associated with longer operative time (223.9 vs. 188.7 min; p = 0.003), decreased use of analgesics (morphine dose 33.9 vs. 43.4 mg; p = 0.011) and duration of hospital stay (4.2 vs. 5.1 days; p = 0.001). No statistically significant difference was found in morbidity or wound-related complication rates between the two groups. After a median follow-up of 34.3 months, no local recurrence was observed in RPLS-NOSE. The 3-year disease-free survival did not differ statistically significantly between groups (90.9 vs. 90.5%; p = 0.610). CONCLUSION: NOSE enhances the advantages of RPLS by avoiding the need for abdominal wall specimen extraction in patients with tumor diameter ≤ 5 cm. Surgical and oncologic safety are comparable to RPLS with CSE.

BACKGROUND: Cytoreductive surgery (CRS) for colorectal cancer peritoneal carcinomatosis has been shown to prolong survival with acceptable morbidity rates. Total pelvic peritonectomy (TPP), or complete removal of all pelvic peritoneum, constitutes an important and technically challenging component of CRS. Here we report our experience and describe our technique of laparoscopic total pelvic peritonectomy (LTPP), using a photographic/videographic step-by-step guide. METHODS: All patients who underwent LTPP for pelvic carcinomatosis from a colorectal origin were included in the study. Only patients with peritoneal cancer index (PCI) score of ≤ 10 were selected for CRS with LTPP. Patients who had extra-abdominopelvic cavity metastases were excluded. The final decision to proceed with CRS was made following laparoscopic assessment. RESULTS: From January 2017 to December 2020, 15 consecutive patients underwent LTPP for colorectal cancer pelvic carcinomatosis. Median patient age and PCI score was 53 years (range 33-78) and 8 (range 3-10), respectively. Complete cytoreduction was achieved in all patients. Thirteen patients (87%) underwent concomitant hyperthermic intraperitoneal chemotherapy (HIPEC). The median operative duration was 748 min (interquartile range [IQR] 681-850). Median intra-operative blood loss and length of hospital stay was 100 ml (IQR 50-300) and 10 days (IQR 8-12), respectively. Five patients (33%) experienced 30-day post-operative morbidity, with one (6.7%) experiencing a higher grade (Clavien-Dindo IIIa) complication. Median follow-up duration was 13 months (IQR 3-19), during which four (27%) had systemic recurrence and one (6.7%) died after 15 months following peritoneal and systemic recurrences. CONCLUSION: LTPP is a feasible option for low-volume pelvic carcinomatosis from colorectal cancer, offering the benefits of a minimally invasive approach. Strict patient selection is essential, and the procedure should be converted if the PCI score cannot be assessed or complete cytoreduction cannot be achieved. Proficiency at laparoscopic pelvic surgery is mandatory for performing LTPP.

BACKGROUND: Efficient bowel cleansing is essential for a successful colonoscopy, but the ideal cleansing agent, volume, and pharmaceutical dosage form have yet to be determined. Small-volume cleansers enhance patient compliance. AIM: To compare the bowel cleansing efficacy of 32-tablet sodium phosphate (Quiklean®) with 2-L polyethylene glycol (PEG)/bisacodyl (Klean-Prep/ Dulcolax®) under identical dietary recommendations. METHODS: This multicenter, randomized, parallel-group, noninferiority clinical trial enrolled 472 outpatients, randomized 456 subjects, and scheduled 442 subjects to undergo colonoscopy (Quiklean® = 222 and Klean-Prep/Dulcolax® = 220). After bowel preparation, a colonoscopist performed the colonoscopy with video recorded for rating. The primary efficacy endpoint was the bowel cleansing quality using the Aronchick Scale. The secondary endpoints were the bowel cleansing efficacy of three colon segments, tolerability and acceptability, safety using the Ottawa bowel preparation scale, questionnaires by subjects, and monitoring of adverse events. RESULTS: Success rates (Excellent + Good) of the bowel cleansing quality by Aronchick Scale were 98.6% (n = 205) and 97.6% (n = 204) in the Quiklean® and Klean-Prep/Dulcolax® groups, respectively. Quiklean® demonstrated noninferiority over Klean-Prep/Dulcolax® in colon cleansing efficacy. Quicken showed better tolerability and acceptability in the overall experience (was rated as excellent; 24.0% vs 17.2%; P = 0.0016) and the taste of the study preparation (was rated as excellent, 23.1% vs 13.4%; P < 0.0001) than Klean-Prep/Dulcolax®. Safety profiles did not differ between the two groups. Our data indicate that Quiklean® is an adequate, well-tolerated bowel cleansing preparation compared with the standard comparator Klean-Prep/Dulcolax®. CONCLUSION: Quiklean® is sodium phosphate tablets available on Taiwan's market for bowel preparation; it potentially offers patients an alternative to standard large-volume bowel preparation regimens and may, therefore, increase positive attitudes toward colonoscopies and participation rates.

BACKGROUND: Although the short-term advantages of natural orifice specimen extraction are widely recognized, controversy exists concerning oncologic safety after laparoscopic surgery for colorectal cancer. OBJECTIVE: This study aimed to investigate the impact of natural orifice specimen extraction on local recurrence and long-term survival of patients undergoing colorectal cancer surgery. DESIGN: This is a propensity score-matched comparative study. SETTING: This study presents a single-center experience. PATIENTS: We retrospectively analyzed the records of patients who underwent curative laparoscopic anterior resection for American Joint Committee on Cancer stage I to III sigmoid or upper rectal cancer in 2011 to 2014, based on prospectively collected data. INTERVENTIONS: Oncologic outcomes were compared between patients undergoing natural orifice or conventional specimen extraction by minilaparotomy. Patients were matched 1:1 according to propensity scores calculated by logistic regression analysis with the following covariates: American Joint Committee on Cancer stage, tumor diameter, age, sex, BMI, and T stage. Cox proportional hazards regression analysis was performed to determine the impact on oncologic outcome. MAIN OUTCOME MEASURES: The primary outcomes measured were local recurrence and disease-free survival rates at 5 years. RESULTS: Of 392 eligible patients, 188 were matched (94 undergoing natural orifice specimen extraction and 94 undergoing conventional extraction by minilaparotomy). Median follow-up was 50.3 months. The cumulative local recurrence risk at 5 years was 2.3% and 3.5% (p = 0.632), whereas 5-year disease-free survival for all tumor stages combined was 87.3% and 82.0% (p = 0.383) in laparoscopic anterior resection with natural orifice specimen extraction and conventional extraction groups. T3 and T4 stages were the only variables independently associated with disease-free survival. LIMITATIONS: This study was limited because it focused on a single center, was a retrospective analysis, contained no long-term anorectal function testing, and had a small sample size. CONCLUSION: Long-term oncologic outcomes of patients undergoing laparoscopic anterior resection with natural orifice specimen extraction for sigmoid and upper rectal cancer do not differ from those undergoing conventional extraction. Thus, natural orifice specimen extraction could be a viable alternative to reduce abdominal wall insult in laparoscopic colorectal operations for malignancy in selected patients.

RESULTADOS ONCOLÓGICOS A LARGO PLAZO DE RESECCIONES ANTERIORES LAPAROSCÓPICAS PARA CÁNCER A TRAVÉS DE ORIFICIO NATURAL FRENTE A EXTRACCIÓN CONVENCIONAL DEL ESPÉCIMEN: UN ESTUDIO DE CASOS Y CONTROLES: Si bien las ventajas a corto plazo de la extracción de especímenes por orificio natural son ampliamente reconocidas, existe controversia con respecto a la seguridad oncológica después de la cirugía laparoscópica para el cáncer colorrectal.Investigar el impacto de la extracción de especímenes por orificio natural en la recurrencia local y la supervivencia a largo plazo de pacientes sometidos a cirugía de cáncer colorrectal.Estudio comparativo con emparejamiento por puntuación de propensión.Experiencia en un centro único.Analizamos retrospectivamente los registros de pacientes que se sometieron a resección anterior laparoscópica curativa para cáncer sigmoideo o rectal superior AJCC en estadio I-III en 2011-2014, con base en datos recolectados prospectivamente.Los resultados oncológicos se compararon entre pacientes sometidos a extracción por orificio natural o convencional mediante minilaparotomía de especímenes. Los pacientes fueron emparejados 1:1 de acuerdo con los puntajes de propensión calculados por análisis de regresión logística con las siguientes covariables: estadio AJCC, diámetro del tumor, edad, sexo, índice de masa corporal y estadio T. Se realizó un análisis de regresión de riesgos proporcionales de Cox para determinar el impacto en el resultado oncológico.Recurrencia local y tasas de supervivencia libre de enfermedad a los 5 años.De 392 pacientes elegibles, 188 fueron emparejados (94 sometidos a extracción de espécimen por orificio natural y 94 a extracción convencional por minilaparotomía). La mediana de seguimiento fue de 50.3 meses. El riesgo cumulativo de recurrencia local a 5 años fue de 2.3% y 3.5% (p = 0.632), mientras que la supervivencia libre de enfermedad a 5 años para todas las etapas tumorales combinadas fue de 87.3% y 82.0% (p = 0.383) en los grupos de resección anterior laparoscópica con extracción de espécimen por orificio natural y extracción convencional, respectivamente. Las etapas T3 y T4 fueron las únicas variables asociadas independientemente con la supervivencia libre de enfermedad.Centro único, análisis retrospectivo, ausencia de pruebas de función anorrectal a largo plazo y tamaño de muestra pequeño.Los resultados oncológicos a largo plazo de los pacientes sometidos a resección anterior laparoscópica con extracción de espécimen por orificio natural para cáncer sigmoideo y rectal superior no difieren de los de aquellos sometidos a extracción convencional. Por lo tanto, la extracción de especímenes por orificio natural podría ser una alternativa viable para reducir el insulto a la pared abdominal en operaciones colorrectales laparoscópicas por malignidad en pacientes selectos.

Taiwan has a lower prevalence of inflammatory bowel disease (IBD) and a higher prevalence of tuberculosis (TB) infection than Western countries. The aim of this study was to investigate the prevalence of latent TB (LTB) and active TB infection in IBD patients treated with biological agents. From January 2000 to September 2018, we retrospectively collected data from IBD patients treated with biological agents at a tertiary referral center. Patients underwent a QuantiFERON-TB Gold test (QFT) to screen for TB infection before and after biological treatment courses. The diagnostic age, sex, body mass index, hepatitis B virus infection, biochemistry profile, treatment regimens, and the results of the QFT were analyzed. Overall, 130 IBD patients who received biological treatment were enrolled. The results of the QFT before biological treatment were determined in 120 patients (92%); of these, 10 were positive (8%), 110 were negative (85%), and 10 were indeterminate (9%). Six patients demonstrated seroconversion after biological treatment, as determined by the QFT. Three patients (2.4%) developed active pulmonary TB after biological treatment. In subgroup analysis, the positive QFT patients had a trend of lower baseline serum C-reactive protein and erythrocyte sedimentation rate levels than the negative QFT group. The present study demonstrates that the prevalence of LTB before and after biological treatment is higher in Taiwan than in most Western countries and similar to other Asian countries. Therefore, screening and monitoring of TB infection are necessary for IBD patients before and during biological treatments in Taiwan.
RESUMO
Anastomotic leaks (ALs) are associated with increased perioperative morbidity and mortality, prolonged length of stay, higher readmission rates, the potential need for further operative interventions, and unintended permanent stomas; resulting in increased hospital costs and resource use, and decreased quality of life. This review article is to present definition, diagnosis and management strategies for AL after rectal surgery.
