Risk factors for non-closure of an intended temporary defunctioning stoma after emergency resection of left-sided obstructive colon cancer
Purpose: A substantial part (21–35%) of defunctioning stomas created during resection for colorectal cancer will never be reversed. Known risk factors for non-closure are age, peri- or postoperative complications, comorbidity, and tumor stage. However, studies performed to identify these risk factors mostly focus on rectal cancer and include both preoperative and postoperative factors. This study aims to identify preoperative risk factors for non-reversal of intended temporary stomas created during acute resection of left-sided obstructive colon cancer (LSOCC) with primary anastomosis. Methods: All patients who underwent emergency resection for LSOCC with primary anastomosis and a defunctioning stoma between 2009 and 2016 were selected from the Dutch ColoRectal Audit, and additional data were collected in the local centers. Multivariable analysis was performed to identify independent preoperative factors for non-closure of the stoma. Results: A total of 155 patients underwent acute resection for LSOCC with primary anastomosis and a defunctioning stoma. Of these, 51 patients (32.9%) did not have their stoma reversed after a median of 53 (range 7–104) months of follow-up. In multivariable analysis, hemoglobin < 7.5 mmol/L (odds ratio (OR) 4.79, 95% confidence interval (95% CI) 1.60–14.38, p = 0.005), estimated glomerular filtration rate (eGFR) ≤ 45 mL/min/1.73 m2 (OR 4.64, 95% CI 1.41–15.10, p = 0.011), and metastatic disease (OR 6.12, 95% CI 2.35–15.94, p < 0.001) revealed to be independent predictors of non-closure. Conclusions: Anemia, impaired renal function, and metastatic disease at presentation were found to be independent predictors for non-reversal of intended temporary stomas in patients who underwent acute resection for LSOCC. In patients who have an increased risk of non-reversal, the surgeon should consider a Hartmann’s procedure.</p
Comparison of anal function and quality of life after conformal sphincter preservation operation and intersphincteric resection of very low rectal cancer: a multicenter, retrospective, case-control analysis
Purpose: Conformal sphincter preservation operation (CSPO) is a sphincter preservation operation for very low rectal cancers. Compared to intersphincteric resection (ISR), CSPO retains more dentate line and distal rectal wall, and also avoids damaging the nerves in the intersphincteric space. This study aimed to compare the postoperative anal function and quality of life between the CSPO and ISR. Method: Patients with low rectal cancer undergoing CSPO (n = 117) and ISR (n = 66) were included from Changhai and Huashan Hospital, respectively, between 2011 and 2020. A visual analog scale (range 0–10) was utilized to evaluate satisfaction with anal function and quality of life. The anal function was evaluated with Wexner scores and low anterior resection syndrome (LARS) score. Quality of life was evaluated with the EORTC QLQ-C30 and QLQ-CR38. Results: The CSPO group had more male patients (65.8% vs. 50%, p = 0.042), more preoperative chemoradiotherapy (33.3% vs. 10.6%, p < 0.001), lower tumor position (3.45 ± 1.13 vs. 4.24 ± 0.86 cm, p < 0.001), and more postoperative chemotherapy (65% vs. 13.6%, p < 0.001) compared to the ISR group. In addition, CSPO patients had shorter postoperative stay (6.63 ± 2.53 vs. 7.85 ± 4.73 days, p = 0.003) and comparable stoma reversal rates within 1 year after surgery (92.16% vs. 96.97%, p = 0.318). Multivariable analysis showed that CSPO significantly contributed to higher satisfaction with anal function (beta = 1.752, 95% CI 0.776–2.728) and with quality of life (beta = 1.219, 95% CI 0.374–2.064), but not to Wexner, LARS score, or EORTC QLQ-C30 and QLQ-CR38. Conclusion: CSPO improved the satisfaction with anal function and quality of life but utilized more preoperative chemoradiotherapy. CSPO may be an alternative choice for patients with very low rectal cancers in better physical health and with higher requirements for anal function and quality of life
Retrospective study of the functional and oncological outcomes of conformal sphincter preservation operation in the treatment of very low rectal cancer
Background Conformal sphincter preservation operation (CSPO) is a new surgical procedure for very low rectal cancers (within 4-5 cm from the anal verge). CSPO preserves more of the dentate line and distal rectal wall and also avoids injuring nerves in the intersphincteric space, resulting in satisfactory anal function after resection. The aim of this study was to analyze the short-term surgical results and long-term oncological and functional outcomes of CSPO. Methods Consecutive patients with very low rectal cancer, who had CSPO between January 2011 and October 2018 at Changhai Hospital, Shanghai were included. Patient demographics, clinicopathological features, oncological outcomes and anal function were analyzed. Results A total of 102 patients (67 men) with a mean age of 56.9 +/- 10.8 years were included. The median distance of the tumor from the anal verge was 3 (IQR, 3-4) cm. Thirty-five patients received neoadjuvant chemoradiation (nCRT). The median distal resection margin (DRM) was 0.5 (IQR, 0.3-0.8) cm. One patient had a positive DRM. All circumferential margins were negative. There was no perioperative mortality. The postoperative complication rate was 19.6%. The median duration of follow-up was 28 (IQR, 12-45.5) months. The local recurrence rate was 2% and distant metastasis rate was 10.8%. The 3-year overall survival and disease-free survival rates were 100% and 83.9%, respectively. The mean Wexner incontinence and low anterior resection syndrome scores 12 months after ileostomy reversal were 5.9 +/- 4.3, and 29.2 +/- 6.9, respectively. Conclusions For patients with very low rectal cancers, fecal continence can be preserved with CSPO without compromising oncological results
The learning effect of intraoperative video-enhanced surgical procedure training
BACKGROUND: The transition from basic skills training in a skills lab to procedure training in the operating theater using the traditional master-apprentice model (MAM) lacks uniformity and efficiency. When the supervising surgeon performs parts of a procedure, training opportunities are lost. To minimize this intervention by the supervisor and maximize the actual operating time for the trainee, we created a new training method called INtraoperative Video-Enhanced Surgical Training (INVEST). METHODS: Ten surgical residents were trained in laparoscopic cholecystectomy either by the MAM or with INVEST. Each trainee performed six cholecystectomies that were objectively evaluated on an Objective Structured Assessment of Technical Skills (OSATS) global rating scale. Absolute and relative improvements during the training curriculum were compared between the groups. A questionnaire evaluated the trainee's opinion on this new training method. RESULTS: Skill improvement on the OSATS global rating scale was significantly greater for the trainees in the INVEST curriculum compared to the MAM, with mean absolute improvement 32.6 versus 14.0 points and mean relative improvement 59.1 versus 34.6% (P = 0.02). CONCLUSION: INVEST significantly enhances technical and procedural skill development during the early learning curve for laparoscopic cholecystectomy. Trainees were positive about the content and the idea of the curriculum
Influence of Conversion and Anastomotic Leakage on Survival in Rectal Cancer Surgery; Retrospective Cross-sectional Study
Short-term outcomes of radical excision vs. phenolisation of the sinus tract in primary sacrococcygeal pilonidal sinus disease: a randomized-controlled trial
Background Phenolisation of Sacrococcygeal pilonidal sinus disease (SPSD) seems to have advantages over radical excision; however, a randomized-controlled trial (RCT) comparing both techniques is lacking. The aim of our study was to compare sinus pit excision and phenolisation of the sinus tract with radical excision in SPSD in terms of return to normal daily activities. Methods This study was a single-center RCT. Fifty patients who presented with primary SPSD were randomized to phenolisation and 50 patients to excision. The primary endpoint was time to return to normal daily activities. Secondary endpoints were quality of life, complaints related to SPSD, surgical site infection, and wound epithelialization. Patients were treated in a 1-day surgery setting. Complaints related to SPSD were evaluated and symptoms were scored by the participants on a 6-point scale before surgery, and patients kept a diary for 2 weeks on complaints related to the surgical treatment (the same scoring system as preoperatively) and pain, evaluated with a VAS. Quality of life (QoL) was measured preoperatively with a VAS and the Short Form-36 Health Survey (SF-36). At 2, 6, and 12 weeks after surgery, patients were evaluated using a questionnaire containing the following items: patients' satisfaction (disease, compared with preoperatively, scored as cured, improved, unchanged or worsened), five complaints related to the surgical treatment (the same scoring system as preoperatively and in the diary), QoL (VAS and SF-36), and return to normal daily activities. The wound was assessed 2, 6, and 12 weeks postoperatively by one of the investigators (EF or NS), using an assessment form Results The mean time to return to normal daily activities was significantly shorter after phenolisation (5.2 +/- SD 6.6 days vs. 14.5 +/- 25.0 days, p = 0.023). 2 weeks after surgery, all patients in the phenolisation group and 85.4% of patients in the excision group returned to normal daily activities (p = 0.026). Pain was significantly lower after phenolisation at 2 weeks postoperatively (0.8 +/- 1.0 vs. 1.6 +/- 1.3, p = 0.003). Surgical site infection occurred significantly more often after radical excision (n = 10, 21.7% vs. n = 2, 4.0%, p = 0.020). At 6 and 12 weeks, complete wound epithelialization was more frequently achieved after phenolisation (69.0% vs. 37.0%, p = 0.003 and 81.0% vs. 60.9%, p = 0.039, respectively). Conclusions Pit excision with phenolisation of SPSD resulted in a quicker return to normal daily activities, less pain, and quicker wound epithelialization compared to radical excision. Surgeons should consider phenolisation in patients with primary SPSD

Long-term Oncologic Outcome After Laparoscopic Converted or Primary Open Resection for Colorectal Cancer:A Systematic Review of the Literature
Purpose: The aim of this study was to critically review the current evidence regarding the oncologic outcomes after laparoscopic converted or open resection for colorectal cancer. Materials and Methods: A literature search was performed in Pubmed. Study selection and data acquisition were independently performed by 2 reviewers. Results: The search strategy yielded a total of 746 articles, resulting in 7 studies eligible for inclusion. A total of 9190 (57 to 8307) patients were included in the open and 238 (17 to 56) in the converted group. In none of the studies, differences were found in disease stage between both groups. There were no significant differences between both groups with regard to overall survival, local recurrence and distant metastasis rate. Conclusions: There is currently insufficient evidence that patients who had a laparoscopic resection for colorectal cancer converted to open surgery have a worse oncologic outcome than patients who were primarily treated by an open approach
The effect of hair removal after surgery for sacrococcygeal pilonidal sinus disease:A systematic review of the literature
Background It has been suggested that removal of body hair in the sacrococcygeal area prevents recurrence after surgery for sacrococcygeal pilonidal sinus disease (SPSD). The aim of this study was to review the literature regarding the effect of hair depilation on the recurrence rate in patients surgically treated for SPSD. Methods A systematic search was performed in PubMed, EMBASE, and The Cochrane Library by using synonyms for SPSD. Title, abstract, and full text were screened by two independent reviewers. Data were systematically collected from all included studies by using a standardized data extraction form. Results The search and selection yielded 14 studies, involving 963 patients. The study design of the included studies was: retrospective cohort (n = 7), prospective cohort (n = 3), randomized controlled trial (n = 2), and case-control (n = 2). The mean length of follow-up was 37.0 (standard error of the mean: 35.0) months. The recurrence rate was 9.3% (34 out of 366 patients) in patients who had laser hair removal, 23.4% (36 out of 154 patients) in those who had razor shaving/cream depilation, and 19.7% (85 out of 431 patients) in those who had no hair removal after surgery for SPSD. Conclusions This systematic review showed a lower recurrence rate after laser hair removal compared to no hair removal and razor/cream depilation. Due to the small sample size and limited methodological quality of the included studies, a highquality randomized controlled trial is required
