RESUMO
BACKGROUND: Transanal minimally invasive surgery (TAMIS) is widely used for rectal lesion excision. Robot-assisted TA TAMIS (R-TAMIS) may improve surgical ergonomics. The introduction of the da Vinci Single-Port (SP) robot, designed for endoluminal surgery, has brought new possibilities. Our primary objective herein was to assess the technical and oncological feasibility and efficacy of Single-port robotic TAMIS (SPR-TAMIS) in rectal cancer excision. The secondary objective was to analyze the perioperative outcomes. MATERIALS AND METHODS: We included 14 consecutive patients with rectal cancer who underwent SPR-TAMIS between April 2021 and February 2023. Patient data, surgical details, and clinical outcome data were collected to assess the safety and feasibility of SPR-TAMIS. RESULTS: The median participant age was 72 years, and full-thickness excision was performed without specimen fragmentation in all cases. The median tumor diameter was 2.7 cm, positioned between 10 cm proximally and 7 cm distally from the anal verge. Negative margins were achieved in 93% of cases, with one case requiring further resection. The median operative time was 175 min, and the median hospital stay was 5 days. No intraoperative conversion from SPR-TAMIS to laparoscopic or conventional transanal excision was required. No mortalities or major postoperative complications occurred; however, one patient (7.1%) experienced minor morbidity manifesting as wound dehiscence (Clavien-Dindo grade I). No recurrence was observed during the 24-month follow-up. CONCLUSIONS: In our early experience, SPR-TAMIS is a safe and feasible surgery for selected early stage rectal cancers, offering enhanced visualization and stable maneuverability transanally. This platform may have potential advantages for the excision of larger or more proximal lesions.
RESUMO
BACKGROUND: This study aimed to investigate the clinical significance of machine-learning (ML) algorithms based on serum inflammatory markers to predict survival outcomes for patients with colorectal cancer (CRC). METHODS: The study included 941 patients with stages I to III CRC. Based on random forest algorithms using 15 compositions of inflammatory markers, four different prediction scores (DFS score-1, DFS score-2, DFS score-3, and DFS score-4) were developed for the Yonsei cohort (training set, n = 803) and tested in the Ulsan cohort (test set, n = 138). The Cox proportional hazards model was used to determine correlation between prediction scores and disease-free survival (DFS). Harrell's concordance index (C-index) was used to compare the predictive ability of prediction scores for each composition. RESULTS: The multivariable analysis showed the DFS score-4 to be an independent prognostic factor after adjustment for clinicopathologic factors in both the training and test sets (hazard ratio [HR], 8.98; 95% confidence interval [CI] 6.7-12.04; P < 0.001 for the training set and HR, 2.55; 95% CI 1.1-5.89; P = 0.028 for the test set]. With regard to DFS, the highest C-index among single compositions was observed in the lymphocyte-to-C-reactive protein ratio (LCR) (0.659; 95% CI 0.656-0.662), and the C-index of DFS score-4 (0.727; 95% CI 0.724-0.729) was significantly higher than that of LCR in the test set. The C-index of DFS score-3 (0.725; 95% CI 0.723-0.728) was similar to that of DFS score-4, but higher than that of DFS score-2 (0.680; 95% CI 0.676-0.683). CONCLUSIONS: The ML-based approaches showed prognostic utility in predicting DFS. They could enhance clinical use of inflammatory markers in patients with CRC.

BACKGROUND: Redo ileocolic resection for recurrent Crohn's disease is associated with increased technical complexity and higher complication rates compared to primary resection. Literature concerning redo surgery for recurrent Crohn's disease is scarce and it is controversial whether a redo is a risk factor for postoperative anastomotic leak. OBJECTIVE: This study aimed to hypothesized that redo ileocolic resection for Crohn's disease is an independent risk factor for anastomotic leak. DESIGN: Retrospective, case-control study from 1994 to 2019 with multivariate analysis and propensity score weighting. SETTING: Quaternary, IBD-referral center. PATIENTS: Adult patients aged >18 years were included in the study. INTERVENTIONS: Primary or redo ileocolic resection with an anastomosis, with or without diverting ileostomy. MAIN OUTCOME MEASURES: Thirty-day anastomotic leak rate. RESULTS: A total of 991 patients (56% primary and 44% redo ileocolic resections) were included. Patients who underwent redo resection were significantly older with more comorbidities, fewer medications, and less fistulizing disease compared to the primary group. On univariate analysis, patients who underwent redo resection had more overall complications (50.5% vs 36.2%, p < 0.001), and the cumulative number of prior ileocolic resections was significantly associated with increased risk for overall morbidity ( p < 0.001). There were 31 (3%) anastomotic leaks; leak rates did not differ between groups ( p = 0.60). Multivariable analysis indicated that extensive adhesiolysis ( p < 0.001), ileostomy omission ( p = 0.009), and intraoperative abscess/fistula ( p = 0.02) were independently associated with leaks but not redo resection ( p = 0.27). Patients with 0, 1, 2, or 3 of these risk factors had observed leak rates of 1.1%, 1.3%, 6.0%, and 11.6.% ( p = 0.03), respectively. LIMITATIONS: The limitations of this study were selection bias, referral bias, and single quaternary center. CONCLUSIONS: Compared to primary procedures, redo ileocolic resection for recurrent Crohn's disease is associated with increased overall morbidity but not anastomotic leak.

Los pacientes de reintervención eran significativamente mayores con más comorbilidades, menos medicamentos y menos enfermedad fistulizante en comparación con el grupo primario. En el análisis univariado, los pacientes reoperados tuvieron más complicaciones generales (50,5% frente a 36,2%, p < 0,001) y el número acumulado de resecciones ileocólicas previas se asoció significativamente con un mayor riesgo de morbilidad general ( p < 0,001). Hubo 31 (3%) fugas anastomóticas; las tasas de fuga no difirieron entre los grupos ( p = 0,6). El análisis multivariado indicó que la adhesiolisis extensa ( p < 0,001), la omisión de ileostomía ( p = 0,009) y el absceso/fístula intraoperatorios ( p = 0,02) se asociaron de forma independiente con fugas, pero no con nueva resección ( p = 0,27).

AIM: Due to their rarity, the management of colorectal gastrointestinal stromal tumours (CR GISTs) is still under debate. The aim of this study was to assess prognostic factors. METHOD: We performed a retrospective review of patients who underwent surgery with curative intent for CR GIST at our centre from 2002 to 2019. Factors associated with overall (OS) and recurrence-free survival (RFS) were analysed. RESULTS: Fifty-six patients were included [median age 63 years, 29 (52%) female, 30 (54%) Miettinen high-risk, 40 (71%) with rectal GIST]. Nineteen (34%) patients received perioperative (neoadjuvant and/or adjuvant) imatinib. All cases of colonic GIST had an R0 resection, compared with 28 (70%) of rectal GISTs. After a median follow-up of 97 months (interquartile range 48-155 months), 14 (25%) deaths and 14 (25%) recurrences occurred. In the high-risk cohort, factors associated with improved RFS were R0 resection (OR 0.19, 95% CI 0.1-0.5, p = 0.002) and perioperative imatinib (OR 0.33, 95% CI 0.42-0.97, p = 0.04). Patients who had received perioperative imatinib had longer RFS (60% vs. 11% at 5 years, p = 0.006) but not OS. In rectal GISTs, 5-year OS was 85% for R0 and 70% for R1 resections (p = 0.164) and 5-year RFS was 85% for R0 and 12% for R1 resection (p < 0.001). When stratifying patients by perioperative imatinib, there were no differences in OS or RFS in the R0 or R1 groups. CONCLUSION: Perioperative imatinib and R0 resection were associated with improved RFS in high-risk patients with CR GIST. In patients with rectal GIST, R1 resection was associated with worse RFS irrespective of perioperative imatinib treatment.

Purpose: A "Smart Cancer Care" platform that integrates patient-reported outcomes (PROs) with management has been established in Korea. This study focused on improving health behaviors and connecting patients to welfare services by introducing and assessing the feasibility of "Smart Cancer Care 2.0," an enhanced version designed for monitoring complications post-cancer treatment. Materials and Methods: Smart Cancer Care 2.0 was developed by conducting a literature review and consulting with expert panels to identify symptoms or variables requiring monitoring and management guidelines based on the treatment type. Qualitative and quantitative surveys were conducted to assess the feasibility of the app and web system based on the experiences of patients with cancer and healthcare workers. Results: A total of 81 symptoms or variables (chemotherapy-, surgery-, radiotherapy-, rehabilitation-, and health management-related) were selected for management in Smart Cancer Care 2.0. PROs for these symptoms were basically categorized into three severity grades: (1) preventive management, (2) self-treatment, and (3) consultation with a healthcare worker or visit to a healthcare institution. The overall mean scores in the feasibility evaluation by patients and healthcare workers were 3.83 and 3.90 points, respectively, indicating high usefulness. Conclusion: Smart Cancer Care 2.0 leverages the existing ICT-based platform, Smart Cancer Care, and further includes health behaviors and welfare services. Smart Cancer Care 2.0 may play a crucial role in establishing a comprehensive post-discharge management system for patients with cancer as it provides suitable interventions based on patients' responses and allows the regularly collected PROs to be easily viewed for streamlined care.
RESUMO
Recent advancements in robotic systems have led to the introduction of the da Vinci SP system, which allows surgeons to perform colon cancer surgery through fewer ports. This study aimed to evaluate the perioperative outcomes of colon cancer surgeries conducted using the da Vinci SP and Xi systems. Patients who underwent robotic colon cancer surgeries between November 2020 and December 2022 at two tertiary referral centers were considered for inclusion. Following propensity-score matching, short-term outcomes between the two systems were retrospectively analyzed. Out of 189 patients included in the study, 106 from 53 propensity-score matched pairs were analyzed. Patients operated on with the SP system exhibited smaller incision lengths (5.0 cm vs. 9.4 cm, p < 0.001) experienced less pain at 8 h (3.0 vs. 3.5, p < 0.001) and at 24 h post-operation (2.9 vs. 3.3, p = 0.001) and had a shorter duration of hospital stay (5 days vs. 6 days, p = 0.002). The overall rate of postoperative complications was 10.4%, with no significant difference between the SP and Xi groups (7.5% vs. 13.2%). Robotic-assisted colon cancer surgery using the da Vinci SP system is feasible and demonstrates favorable short-term outcomes. Compared to the Xi system, the SP system offers advantages in terms of cosmesis, postoperative pain, and recovery duration for colon cancer patients.

BACKGROUND: The rupture of a splenic artery aneurysm (SAA) in pregnancy is an uncommon condition. However, it is associated with high mortality rates in pregnant women and fetuses even after surgical treatment. Though the endovascular treatment of SAAs is currently preferred as it can improve the outcomes even in emergent cases, the endovascular treatment of a ruptured SAA during pregnancy has not been reported until date. CASE SUMMARY: We report a case of a 33-year-old woman with the sudden onset of epigastric pain due to a ruptured SAA at the mid-portion of the splenic artery at 18 wk of pregnancy. After emergent initial resuscitation, the patient was diagnosed with a ruptured SAA through digital angiography. Immediately upon diagnosis, she underwent emergent endovascular embolization of the splenic artery for the rupture on the spot. Next, surgery was performed to remove the hematoma under stable conditions. Although the fetus was found to be dead during resuscitation, the woman recovered without complications and was discharged 15 d postoperatively. CONCLUSION: Endovascular treatment might be a valuable alternative to surgery/lead to safer surgery for selected pregnant patients with ruptured SAAs.
RESUMO
PURPOSE: To evaluate the clinical significance of a reduction in serum carcinoembryonic antigen (s-CEA) concentration ratio from before to after preoperative chemoradiotherapy (CRT) in terms of recurrence and prognostic factors in rectal cancer patients. METHODS: We retrospectively evaluated 333 rectal cancer patients who received preoperative CRT followed by surgery with curative intent between January 2000 and December 2006. Patients were divided into three groups: those with pre-CRT s-CEA≤6 ng/mL (group 1), those with pre-CRT s-CEA>6 mg/mL and post-CRT s-CEA≥70% lower than pre-CRT s-CEA (group 2), and those with pre-CRT s-CEA>6 mg/mL and post-CRT s-CEA<70% lower or higher than pre-CRT s-CEA (group 3). RESULTS: The 5-year disease-free survival rate was similar in group 1 (76.0%) and group 2 (66.0%), but significantly lower in group 3 (39.5%) (p<0.001). Multivariate analysis showed that CEA group 3, ypT stage, ypN stage, and type of surgery were independent prognostic factors for disease-free survival. CONCLUSIONS: The reduction ratio of pre- to post-CRT s-CEA concentration may be an independent prognostic factor for disease-free survival following preoperative CRT and surgery in rectal cancer patients with initial s-CEA>6 ng/mL.

BACKGROUND: The occurrence of venous thromboembolism (VTE), manifesting as deep vein thrombosis (DVT) or pulmonary embolism (PE), after colorectal cancer surgery in Asian patients remains poorly characterized. The present study was designed to investigate the incidence of symptomatic VTE in Korean colorectal cancer patients following surgery, and to identify the associated risk factors. METHODS: We retrospectively analyzed data from patients who developed symptomatic VTE after colorectal cancer surgery between 2006 and 2008. Deep vein thrombosis was diagnosed with Doppler ultrasound or contrast venography, and PE was identified with lung ventilation/perfusion scans or chest computed tomography. Thromboprophylaxis, including low-molecular-weight heparin, graduated compression stockings, and intermittent pneumatic compression, was used in patients considered at high risk of VTE. RESULTS: Of the 3,645 patients who underwent colorectal cancer surgery, 31 (0.85%) developed symptomatic VTE. Of those 31 patients, 23 (74.2%) had DVT, 16 (51.6%) had PE, and 8 (25.8%) had both. Two patients died from PE. Univariate analysis showed that a history of VTE, pre-existing cardiovascular disease, respiratory disease, transfusions, postoperative immobilization time, and postoperative complications were associated with VTE (p < 0.05 for each). Multivariate analysis showed that a history of VTE, pre-existing cardiovascular disease, postoperative complication, advanced cancer stage, and postoperative immobilization time were risk factors for developing symptomatic VTE. The mean hospital stay was 18.3 days, and the mortality rate was 6.5%. CONCLUSIONS: The incidences of symptomatic DVT and PE were found to be not low in Asian colorectal cancer surgery patients compared with Western countries. The risk factors for VTE were a history of VTE, pre-existing cardiovascular disease, postoperative complications, advanced cancer stage, and postoperative immobilization. Thromboprophylaxis should be strongly considered in patients with these characteristics. Large prospective randomized controlled trials should be conducted to further evaluate the risk of VTE in Asian patients, and to determine the optimal prophylaxis.

Purpose: To describe our experience with phytobezoars, evaluate risk factors on treatment, and analyze whether previous gastric surgery affects treatment outcomes. Methods: Medical records of 51 patients with phytobezoars between 2000 and 2019 were retrospectively evaluated. We compared endoscopic and surgical treatment groups and evaluated risk factors using multivariate logistic regression analysis. And we compared patients with and without previous gastric surgery in the surgical treatment group. Results: The median patient age was 62.9 (range: 27-89) years. The endoscopic and surgical treatment groups included 26 (51%) and 25 (49%) patients, respectively. Patients aged ≥65 years, diabetes, and small intestinal phytobezoars were more frequent in the surgical treatment group. Previous gastric surgery (n = 16, 31.4%) was the most common predisposing risk factor, but without a significant difference between the groups. Enterotomy was performed for 20 patients (80%), segmental resection was performed for five patients (20%). Five patients (20%) had postoperative complications; there was one death. There were no significant differences in age, preoperative diagnosis, operation method, operative time, or postoperative stay between patients with and without previous gastric surgery, but postoperative complications were significantly more common in patients with previous gastric surgery. Conclusions: Phytobezoar should be suspected early in patients with previous gastric surgery or a specific food intake history. Early diagnosis and treatment are important for avoiding surgical intervention and complications, especially in elderly patients. Surgery is required in most patients with small intestinal phytobezoars, safe removal can be achieved mainly via enterotomy.
RESUMO
We report the case of a 31-year-old man with superior mesenteric artery syndrome after reoperation due to postoperative complications from rectal cancer. Although initial total parenteral nutrition (TPN) therapy failed, he underwent endoscopy-assisted feeding tube placement without complications instead of surgery. After 2 weeks of dual feeding (enteral feeding and TPN), he improved, gaining 6 kg; and an oral diet was advanced.

PURPOSE: The aim of this study was to investigate the relationship between the anatomical location of thrombi in the lower extremities and the development of pulmonary embolism (PE). MATERIALS AND METHODS: We collected and analyzed the data of patients diagnosed with deep vein thrombosis (DVT) of the lower extremities between 2006 and 2015, and included those whose computed tomography (CT) data were available for PE identification. We evaluated the relationship between the laterality and the proximal/distal location of the thrombi in lower extremites and the location of PE. RESULTS: CT images were available for 388/452 patients with DVT. After excluding 32 cases with bilateral involvement, 356 cases were included for analysis in this study. The ratio of DVT in the left:right leg was 232:124. PEs developed in 121 (52.2%) patients with left-sided DVT and in 78 (62.9%) with right-sided DVT (P=0.052). PEs in the main pulmonary arteries developed in 36 (15.5%) patients with left leg DVT and in 30 (24.2%) with right leg DVT (P=0.045). The most frequent site of thrombosis associated with the development of PE was the left iliac vein (59/199, 29.6%). According to the anatomical segment of the leg affected by DVT, patients with DVT in the right femoral vein (50/71, 70.4%; P=0.016) had the highest rate of occurrence of PE. CONCLUSION: PE develops more frequently in patients with right-sided DVT than in those with left-sided DVT. Therefore, careful observation for the possible development of PE is recommended in cases with right-sided DVT of the lower extremity.
RESUMO
The mortality and morbidity rates of non-tubal ectopic pregnancies with abdominal hemorrhaging are 7-8 times higher than those of tubal pregnancies. Diaphragmatic pregnancy is a rare non-tubal ectopic form, causing acute abdominal hemoperitoneum. Here, we present a case of a primary diaphragmatic ectopic pregnancy with hemorrhage that was immediately diagnosed and successfully managed with laparoscopic surgery. Rapid and accurate diagnosis using appropriate imaging modalities is critical for improving the prognosis of a child-bearing woman with an abdominal pregnancy.
RESUMO
BACKGROUND: Since the first report of a diaphragmatic hernia from Ambroise Paré's necropsy in 1610, the Bochdalek hernia (BH) of the congenital diaphragmatic hernia (CDH) has been the most common types with high morbidity and mortality in the neonatal period. Due to the nature of the disease, CDH associated with pregnancy is too infrequent to warrant reporting in the literature. Mortality of obstruction or strangulation is mostly due to failure to diagnose symptoms early. DATA SOURCES AND STUDY SELECTION: A systematic literature search of maternal BH during pregnancy was conducted using the electronic databases (PubMed and EMBASE) from January 1941 to December 2020. Because of the rarity of the disease, this review included all primary studies, including case reports or case series that reported at least one case of maternal BH in pregnant. Searches, paper selection, and data extraction were conducted in duplicate. The analysis was performed narratively regardless of the control groups' presence due to their rarity. RESULTS: The search retrieved 3450 papers, 94 of which were deemed eligible and led to a total of 43 cases. Results of treatment showed 16 cases in delayed delivery after hernia surgery, 10 cases in simultaneous delivery with hernia surgery, 3 cases in non-surgical treatment, and 14 cases in hernia surgery after delivery. Of 16 cases with delayed delivery after hernia surgery, 13 (81%) cases had emergency surgery and three (19%) cases had surgery after expectant management. Meanwhile, 10 cases underwent simultaneous delivery with hernia surgery, 6 cases (60%) had emergent surgery, and 4 cases (40%) had delayed hernia surgery after expectant management. 3 cases underwent non-surgical treatment. In this review, the maternal death rate and fetal/neonatal loss rate from maternal BH was 5% (2/43) and 16% (7/43), respectively. The preterm birth rate has been reported in 35% (15/43) of maternal BH, resulting from maternal deaths in 13% (2/15) of cases and 6 fetal loss in 40% (6/15) of cases; 44% (19/43) of cases demonstrated signs of bowel obstruction, ischemia, or perforation of strangulated viscera in the operative field, resulting from maternal deaths in 11% (2/19) of cases and fetal-neonatal loss in 21% (4/19) of cases. CONCLUSION: Early diagnosis and surgical intervention are imperative, as a gangrenous or non-viable bowel resection significantly increases mortality. Therefore, multidisciplinary care should be required in maternal BH during pregnancies that undergo surgically repair, and individualized care allow for optimal results for the mother and fetus.
RESUMO
PURPOSE: To evaluate the effectiveness of endoscopic submucosal resection with a ligation device (ESMR-L) on histologic complete resection for the treatment of small rectal carcinoid tumors in comparison with the treatment with endoscopic mucosal resection (EMR) alone. METHODS: Thirty-five patients with small rectal carcinoid tumors were enrolled prospectively for ESMR-L, and we retrospectively reviewed 74 carcinoid tumor patients who underwent EMR. The comparison between ESMR-L and EMR groups was analyzed including endoscopic and histologic complete resection and complications after resection. We also evaluated the associations of histologic complete resection with clinical and procedure-related factors. RESULTS: The histologic complete resection rate was significantly higher in ESMR-L than in EMR (94.3% vs. 75.7%, P=0.019). In addition, the resection time was significantly shorter in ESMR-L than in EMR (4.16±1.48 min vs. 5.11±2.47 min, respectively, P=0.014). Moreover, previously biopsied rectal carcinoid tumors were significantly associated with histologic incomplete resection, especially in patients who underwent EMR (odds ratio, 6.28; 95% confidence interval, 1.92-20.58; P=0.002). CONCLUSIONS: Compared with EMR, ESMR-L is a safe and effective method for histologic complete resection of small rectal carcinoid tumors, especially in patients with previously biopsied carcinoid tumors.
