Ann Surg Treat Res 2024; 106:93-105. [PMID: 38318094 PMCID: PMC10838655 DOI: 10.4174/astr.2024.106.2.93] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Revised: 12/12/2023] [Accepted: 12/19/2023] [Indexed: 02/07/2024] Open
Abstract
Purpose Patients with obstructive colorectal cancer managed by emergency surgery show high morbidity, mortality, and stoma formation rates. Decompression modalities, including the self-expandable metallic stent (SEMS) and tube drainage (TD), have been used to improve surgical outcomes. However, there have been limited studies comparing the 2 modalities. We performed a meta-analysis on short- and long-term outcomes between SEMS and TD. Methods PubMed, EMBASE, Cochrane Library, and Google Scholar were searched. Data were pooled, and the overall effect size was calculated using random effect models. Outcome measures were perioperative short-term and 3-year survival outcomes. Results We included 20 nonrandomized studies that examined 2,047 patients in the meta-analysis. The meta-analysis showed SEMS had better short-term outcomes in clinical success rate, decompression-related complications, laparoscopic surgery rate, stoma formation rate, and postoperative complication rate with a relative risk (RR) of 0.36 (95% confidence interval [CI], 0.24-0.54; I2 = 20%), 0.32 (95% CI, 0.20-0.50; I2 = 0%), 0.47 (95% CI, 0.34-0.66; I2 = 87%), 0.34 (95% CI, 0.24-0.49; I2 = 52%), and 0.70 (95% CI, 0.54-0.89, I2 = 28%), respectively. However, there was no significant difference between the 2 groups in 3-year overall survival (RR, 0.99; 95% CI, 0.77-1.27; I2 = 0%). Conclusion Although the long-term oncologic impact of SEMS is still unclear compared with TD, the results of this meta-analysis may suggest that SEMS insertion can be performed more successfully and safely and may have benefits for short-term perioperative outcomes compared with TD. Further studies are warranted to provide more definitive survival results.

Abstract
BACKGROUND Colonic stenting reduces morbidity and stoma formation for left-sided colon cancer obstruction, and a prolonged interval between stenting and surgery with neoadjuvant chemotherapy administered might result in a lower stoma rate and tumor reduction. OBJECTIVE The study aimed to evaluate the short-term outcomes of elective surgery following colonic stenting compared with elective surgery following colonic stenting and neoadjuvant chemotherapy in patients with left-sided colon cancer obstruction. DESIGN This is a prospective multicenter cohort study. SETTINGS This study was conducted at 5 medical centers. PATIENTS Patients ( n = 100) with acute left-sided colon cancer obstruction undergoing colonic stenting between December 2015 and December 2019 were included. INTERVENTIONS Patients were assigned to the stenting-alone or chemotherapy group. MAIN OUTCOME MEASURES The primary outcomes measured were laparoscopic surgery and stoma rate. RESULTS Of the 100 patients who underwent colonic stenting, 52 were assigned to the stenting group and 48 were assigned to the chemotherapy group. No statistically significant differences were detected in stent-related complications. The adverse events associated with neoadjuvant chemotherapy were well tolerated. The level of hemoglobin (117.2 vs 107.6 g/L; p = 0.008), albumin (34.2 vs 31.5 g/L; p < 0.001), and prealbumin (0.19 vs 0.16 g/L; p = 0.001) was significantly increased, and the bowel wall thickness (1.09 vs 2.04 mm; p < 0.001) was significantly decreased preoperatively in the chemotherapy group compared with the stenting group. The number of mean harvested lymph nodes was greater in the chemotherapy group than in the stenting group (25.6 vs 21.8; p = 0.04). Laparoscopic surgery was performed more frequently (77.1% vs 40.4%; p < 0.001) and a stoma was created less frequently (10.4% vs 28.8%; p = 0.02) in the chemotherapy group than in the stenting group. LIMITATIONS This trial was limited by the nonrandomized design and a short follow-up period. CONCLUSIONS This study suggests that elective surgery following neoadjuvant chemotherapy and colonic stenting is a safe, effective, and well-tolerated treatment approach with a high laparoscopic resection rate and a low stoma rate.

RESULTADOS A CORTO PLAZO DE LA CIRUGA ELECTIVA SEGUIDO DE STENT METLICO AUTOEXPANDIBLE Y QUIMIOTERAPIA NEOADYUVANTE EN PACIENTES CON OBSTRUCCIN POR CNCER DE COLON IZQUIERDO ANTECEDENTES:La colocación de stents colónicos reduce la morbilidad y la formación de estomas por obstrucción por cáncer de colon izquierdo, y el intervalo prolongado entre la colocación de stents y la cirugía con quimioterapia neoadyuvante administrada podría resultar en una menor tasa de estomas y reducción del tumor.OBJETIVO:Evaluar los resultados a corto plazo de la cirugía electiva después de la colocación de stent en el colon en comparación con la cirugía electiva después de la colocación de stent en el colon y la quimioterapia neoadyuvante en pacientes con obstrucción por cáncer de colon izquierdo.DISEÑO:Estudio prospectivo de cohorte multicéntrico.ENTORNO CLINICO:Este estudio se realizó en 5 centros médicos.PACIENTES:Se incluyeron pacientes (n=100) con obstrucción aguda por cáncer de colon izquierdo que se sometieron a colocación de stent colónico entre diciembre de 2015 y diciembre de 2019.INTERVENCIONES:Los pacientes fueron asignados al grupo de stent solo o quimioterapia.MEDIDAS DE RESULTADO PRINCIPALES:Los resultados primarios medidos fueron la cirugía laparoscópica y la tasa de ostomía.RESULTADOS:De los 100 pacientes que se sometieron a la colocación de stent colónico, 52 fueron asignados al grupo de colocación de stent y 48 al grupo de quimioterapia. No se detectaron diferencias estadísticamente significativas en las complicaciones relacionadas con el stent. Los eventos adversos asociados con la quimioterapia neoadyuvante fueron bien tolerados. Hemoglobina (117,2 g/l vs. 107,6 g/l; p = 0,008), albúmina (34,2 g/l vs. 31,5 g/l; p < 0,001) y prealbúmina (0,19 g/l vs. 0,16 g/l; p = 0,001) aumentaron significativamente y el grosor de la pared intestinal (1,09 mm vs. 2,04 mm; p < 0,001) disminuyó significativamente antes de la operación en el grupo de quimioterapia en comparación con el grupo de colocación de stent. El número medio de ganglios linfáticos extraídos fue mayor en el grupo de quimioterapia que en el grupo de stent (25,6 vs. 21,8; p = 0,04). La cirugía laparoscópica se realizó con mayor frecuencia (77,1 % vs. 40,4 %; p < 0,001) y se creó un estoma con menos frecuencia (10,4 % vs. 28,8 % ; p = 0,02) en el grupo de quimioterapia que en el grupo de colocación de stent.LIMITACIONES:Este ensayo estuvo limitado por el diseño no aleatorio y el corto período de seguimiento.CONCLUSIONES:Este estudio sugiere que la cirugía electiva después de la quimioterapia neoadyuvante y la colocación de stent colónico es un tratamiento seguro, efectivo y bien tolerado, con una alta tasa de resección laparoscópica y una baja tasa de estoma.

Long-term outcomes between self-expandable metallic stent and transanal decompression tube for malignant large bowel obstruction: A multicenter retrospective study and meta-analysis. Ann Gastroenterol Surg 2023; 7:583-593. [PMID: 37416739 PMCID: PMC10319605 DOI: 10.1002/ags3.12664] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Revised: 01/25/2023] [Accepted: 02/05/2023] [Indexed: 07/08/2023] Open
Abstract
Aim To compare the oncological outcomes between self-expandable metallic stent (SEMS) as a bridge to surgery and transanal decompression tube (TDT) placement for malignant large bowel obstruction (MLBO). Methods A total of 287 MLBO patients who underwent SEMS (n = 137) or TDT placement (n = 150) were enrolled in this multicenter retrospective study. Overall survival (OS) and disease-free survival (DFS) between the two groups were compared. A meta-analysis was performed using random-effects models to calculate odd ratios (OR) with 95% confidence intervals (CIs). Results Postoperative complications of Clavien-Dindo grade ≥II and ≥III occurred frequently in the TDT group compared with the SEMS group (P = 0.002 and 0.005, respectively). The 3-y OS in the overall cohort and 3-y DFS in the pathological stage II/III cohort in the SEMS and TDT groups were 68.6% and 71.4%, and 71.0% and 72.6%, respectively. The survival differences were not significantly different in the OS and DFS analyses (P = 0.819 and P = 0.892, respectively). A meta-analysis of nine studies (including our cohort data) demonstrated no significant difference between the SEMS and TDT groups for 3-y OS and DFS (OR = 0.96, 95% CI = 0.57-1.62, P = 0.89 and OR = 0.69, 95% CI = 0.46-1.04, P = 0.07, respectively). Conclusion Our study demonstrated that SEMS placement had no inferiority regarding long-term outcomes, including OS and DFS, compared with TDT placement. Considering the short-term benefits of SEMS placement, this could be a preferable preoperative decompression method for MLBO.

Surgical management and outcomes of obstructive colorectal cancer in elderly patients: A multi-institutional retrospective study. Surgery 2022; 172:60-68. [PMID: 34998620 DOI: 10.1016/j.surg.2021.12.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Revised: 12/04/2021] [Accepted: 12/08/2021] [Indexed: 11/21/2022]
Abstract
BACKGROUND The outcomes and prognostic factors of elderly patients with obstructive colorectal cancer are unknown. This was the focus of our multi-institutional retrospective study. METHODS Medical records of 520 patients (elderly [group E, aged ≥75 years, n = 271]; and nonelderly [group NE, aged <75 years, n = 249]) who received treatment for obstructive colorectal cancer in 2008 to 2018 at 14 leading hospitals in Kagawa prefecture (Japan) were reviewed. Short- and long-term outcomes of patients who underwent tumor resection (n = 438) were compared between the groups. Their prognostic factors were identified. RESULTS The tumor resection rate was 79% (n = 213) and 90% (n = 225) in groups E and NE, respectively. Group E had more emergency resections (27 [12.7%] vs 15 [6.6%], P = .037), shorter operating times (194 vs 221 min, P < .001), fewer dissected lymph nodes (14 vs 17, P = .004), and less adjuvant chemotherapy (47 [26.8%] vs 122 [76.7%], p < .001) than group NE. Postoperative complication rates and recurrence-free survival were not significantly different between the groups. Overall survival was significantly lower in group E than in group NE. Distant metastases and no postoperative chemotherapy were independent poor prognostic factors for overall survival in groups E and NE. Emergency resection (hazard ratio:1.83; 95% confidence interval: 1.02-3.26) was a significant poor prognostic indicator in group E only. CONCLUSIONS The short-term outcomes and recurrence-free survival of elderly and nonelderly patients with obstructive colorectal cancer were similar, although the 90-day mortality rate of the elderly patients was higher. Furthermore, elective surgery after bowel decompression is associated with a better outcome in the elderly.

Comparison of the prognosis of four different treatment strategies for acute left malignant colonic obstruction: a systematic review and network meta-analysis. World J Emerg Surg 2021; 16:11. [PMID: 33736680 PMCID: PMC7977175 DOI: 10.1186/s13017-021-00355-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2020] [Accepted: 02/23/2021] [Indexed: 02/07/2023] Open
Abstract
Background There is controversy regarding the efficacy of different treatment strategies for acute left malignant colonic obstruction. This study investigated the 5-year overall survival (OS) and disease-free survival (DFS) of several treatment strategies for acute left malignant colonic obstruction. Methods We searched for articles published in PubMed, Embase (Ovid), MEDLINE (Ovid), Web of Science, and Cochrane Library between January 1, 2000, and July 1, 2020. We screened out the literature comparing different treatment strategies. Evaluate the primary and secondary outcomes of different treatment strategies. The network meta-analysis summarizes the hazard ratio, odds ratio, mean difference, and its 95% confidence interval. Results The network meta-analysis involved 48 articles, including 8 (randomized controlled trials) RCTs and 40 non-RCTs. Primary outcomes: the 5-year overall survival (OS) and disease-free survival (DFS) of the CS-BTS strategy and the DS-BTS strategy were significantly better than those of the ES strategy, and the 5-year OS of the DS-BTS strategy was significantly better than that of CS-BTS. The long-term survival of TCT-BTS was not significantly different from those of CS-BTS and ES. Secondary outcomes: compared with emergency resection (ER) strategies, colonic stent-bridge to surgery (CS-BTS) and transanal colorectal tube-bridge to surgery (TCT-BTS) strategies can significantly increase the primary anastomosis rate, CS-BTS and decompressing stoma-bridge to surgery (DS-BTS) strategies can significantly reduce mortality, and CS-BTS strategies can significantly reduce the permanent stoma rate. The hospital stay of DS-BTS is significantly longer than that of other strategies. There was no significant difference in the anastomotic leakage levels of several treatment strategies. Conclusion Comprehensive literature research, we find that CS-BTS and DS-BTS strategies can bring better 5-year OS and DFS than ER. DS-BTS strategies have a better 5-year OS than CS-BTS strategies. Without considering the hospital stays, DS-BTS strategy is the best choice. Supplementary Information The online version contains supplementary material available at 10.1186/s13017-021-00355-2.

Abstract
Background This study aimed to evaluate the safety and feasibility of self-expanding metallic stent (SEMS) followed by neoadjuvant chemotherapy prior to elective surgery for obstructing left-sided colon cancer. Methods Eleven consecutive patients with obstructing left-sided colon cancer between May 2014 and November 2015 were included retrospectively. All patients received SEMS followed by neoadjuvant chemotherapy. The primary outcome measure was stoma and laparoscopic surgery. Results Chemotherapy was with two cycles of CAPOX (54.5%) or three cycles mFOLFOX6 (45.5%). Median serum albumin and hemoglobin levels before surgery were significantly higher than before neoadjuvant chemotherapy (p = 0.01 and p = 0.008 respectively) and before SEMS (p = 0.01 and p = 0.003 respectively). Median bowel wall thickness proximal to the upper edge of tumor was significantly more before neoadjuvant chemotherapy than before stent (p = 0.003), and significantly less before surgery than before neoadjuvant chemotherapy (p = 0.003). No patient underwent stoma creation. Laparoscopic surgery was performed in nine (81.8%) patients. No local recurrence or metastases developed over median cancer-specific follow-up of 44 months (range, 37–55 months). Conclusion SEMS followed by neoadjuvant chemotherapy prior to elective surgery appears to be safe and well tolerated in patients with obstructing left-sided colon cancer.
