This study aims to discuss the principles and pillars of robotic colorectal surgery training and share the training pathway at Portsmouth Hospitals University NHS Trust. A narrative review is presented to discuss all the relevant and critical steps in robotic surgical training. Robotic training requires a stepwise approach, including theoretical knowledge, case observation, simulation, dry lab, wet lab, tutored programs, proctoring (in person or telementoring), procedure-specific training, and follow-up. Portsmouth Colorectal has an established robotic training model with a safe stepwise approach that has been demonstrated through perioperative and oncological results. Robotic surgery training should enable a trainee to use the robotic platform safely and effectively, minimize errors, and enhance performance with improved outcomes. Portsmouth Colorectal has provided such a stepwise training program since 2015 and continues to promote and augment safe robotic training in its field. Safe and efficient training programs are essential to upholding the optimal standard of care.

Abstract PDF

Tissue engineering and regenerative medicine (TERM) is an emerging field that has provided new therapeutic opportunities by delivering innovative solutions. The development of nontraditional therapies for previously unsolvable diseases and conditions has brought hope and excitement to countless individuals globally. Many regenerative medicine therapies have been developed and delivered to patients clinically. The technology platforms developed in regenerative medicine have been expanded to various medical areas; however, their applications in colorectal surgery remain limited. Applying TERM technologies to engineer biological tissue and organ substitutes may address the current therapeutic challenges and overcome some complications in colorectal surgery, such as inflammatory bowel diseases, short bowel syndrome, and diseases of motility and neuromuscular function. This review provides a comprehensive overview of TERM applications in colorectal surgery, highlighting the current state of the art, including preclinical and clinical studies, current challenges, and future perspectives. This article synthesizes the latest findings, providing a valuable resource for clinicians and researchers aiming to integrate TERM into colorectal surgical practice.

Abstract PDF: Purpose
Advancements in gastrointestinal surgery have directed attention toward optimizing recovery, including through the use of feeding methods that reduce prolonged postoperative hospital stays, complications, and mortality, among other undesirable outcomes. This study’s primary goals were to identify current peer-reviewed literature reporting the postoperative outcomes of elective bowel surgery and to evaluate the clinical evidence of patients’ tolerance to oral feeding following elective bowel surgery.
Methods
An exhaustive literature search was conducted via PubMed and Scopus. The search results were screened for potential articles, and articles were assessed for eligibility based on prespecified eligibility criteria. The data were synthesized, and the results were reported and discussed thematically.
Results
The database search yielded 1,667 articles, from which 18 randomized controlled trials were chosen for inclusion in this study. This study included 874 early oral feeding (EOF) patients, 865 traditional oral feeding patients, and 91 patients whose postoperative care was unspecified. Data synthesis was done, and meta-analyses were conducted. The results showed that EOF patients required a significantly shorter time to tolerate a solid diet and had shorter hospital stays. In addition, bowel function was restored earlier in EOF groups.
Conclusion
The results show good tolerance to EOF, shorter hospitalizations, and faster restoration of bowel function, suggesting that EOF after elective bowel surgery is relatively safe. However, further studies with similar baseline conditions should be conducted to verify these results.

Abstract PDF: Anastomotic and rectal stump leaks are feared complications of colorectal surgery. Diverting stomas are commonly used to protect low rectal anastomoses but can have adverse effects. Studies have reported favorable outcomes for transanal drainage devices instead of diverting stomas. We describe our use of the Heald anal stent and its potential impact in reducing anastomotic or rectal stump leak after elective or emergency colorectal surgery. We performed a single-center retrospective analysis of patients in whom a Heald anal stent had been used to “protect” a colorectal anastomosis or a rectal stump, in an elective or emergency context, for benign and malignant pathology. Intraoperative and postoperative outcomes were reviewed using clinical and radiological records. The Heald anal stent was used in 93 patients over 4 years. Forty-six cases (49%) had a colorectal anastomosis, and 47 (51%) had an end stoma with a rectal stump. No anastomotic or rectal stump leaks were recorded. We recommend the Heald anal stent as a simple and affordable adjunct that may decrease anastomotic and rectal stump leak by reducing intraluminal pressure through drainage of fluid and gas.

Minimally invasive colorectal surgery is currently well-accepted, with open techniques being reserved for very difficult cases. Laparoscopic colectomy has been proven to have lower mortality, complication, and ostomy rates; a shorter median length of stay; and lower overall costs when compared to its open counterpart. This trend is seen in both benign and malignant indications. Natural orifice specimen extraction surgery (NOSES) in colorectal surgery was first described in the early 1990s. Three recent meta-analyses comparing transabdominal extraction against NOSES concluded that NOSES was superior in terms of overall postoperative complications, recovery of gastrointestinal function, postoperative pain, aesthetics, and hospital stay. However, NOSES was associated with a longer operative time. Herein, we present our technique of robotic NOSES anterior resection using the da Vinci Xi platform in diverticular disease and sigmoid colon cancers.

Abstract PDF

In Western countries, the gold-standard therapeutic strategy for rectal cancer is preoperative chemoradiotherapy (CRT) following total mesorectal excision (TME), without lateral lymph node dissection (LLND). However, preoperative CRT has recently been reported to be insufficient to control lateral lymph node recurrence in cases of enlarged lateral lymph nodes before CRT, and LLND is considered necessary in such cases. We performed a literature review on aspects of pelvic anatomy associated with rectal surgery and LLND, and then combined this information with our experience and knowledge of pelvic anatomy. In this review, drawing upon research using a 3-dimensional anatomical model and actual operative views, we aimed to clarify the essential anatomy for LLND. The LLND procedure was developed in Asian countries and can now be safely performed in terms of functional preservation. Nonetheless, the longer operative time, hemorrhage, and higher complication rates with TME accompanied by LLND than with TME alone indicate that LLND is still a challenging procedure. Laparoscopic or robotic LLND has been shown to be useful and is widely performed; however, without a sufficient understanding of anatomical landmarks, misrecognition of vessels and nerves often occurs. To perform safe and accurate LLND, understanding the landmarks of LLND is essential.

Abstract PDF

Sarcopenia, which is characterized by progressive and generalized loss of skeletal muscle mass and strength, has been well described to be associated with numerous poor postoperative outcomes, such as increased perioperative mortality, postoperative sepsis, prolonged length of stay, increased cost of care, decreased functional outcome, and poorer oncological outcomes in cancer surgery. Multimodal prehabilitation, as a concept that involves boosting and optimizing the preoperative condition of a patient prior to the upcoming stressors of a surgical procedure, has the purported benefits of reversing the effects of sarcopenia, shortening hospitalization, improving the rate of return to bowel activity, reducing the costs of hospitalization, and improving quality of life. This review aims to present the current literature surrounding the concept of sarcopenia, its implications pertaining to colorectal cancer and surgery, a summary of studied multimodal prehabilitation interventions, and potential future advances in the management of sarcopenia.

Abstract PDF

Complications after colorectal surgery remain inevitable, and anastomotic leakage is one of the most severe and potentially fatal complications. Generally, anastomotic leakage is associated with severe peritonitis, the need for emergency reoperation, and an increased mortality rate. Additionally, particularly after rectal cancer surgery, it has a negative impact on long-term outcomes, including postoperative anorectal function, local recurrence, and survival. To prevent anastomotic leakage, understanding the characteristics of each anastomotic technique and establishing a stable anastomotic procedure are important. Transanal total mesorectal excision (TaTME) is a relatively new advanced surgical access technique for pelvic dissection and facilitates different anastomotic techniques without the need for transabdominal rectal transection. Especially, stapled anastomosis in TaTME, also known as double purse-string circular stapled anastomosis or the single stapling technique (SST), has gained much attention as an alternative to the conventional double stapling technique (DST). In this article, we describe the DST, SST, and hand-sewn anastomosis as anastomotic techniques after rectal surgery, focusing mainly on the differences between conventional anastomotic techniques and SST in TaTME. Furthermore, the blood flow evaluation method for the reconstructive colon before anastomosis, which is extremely important in anastomotic leakage prevention regardless of the anastomotic type, is also described.

Purpose
This study aimed to review the outcomes of redo procedures for failed colorectal or coloanal anastomoses.
Methods
A systematic review was performed using the PubMed, Embase, Cochrane, and LILACS databases. The inclusion criteria were adult patients undergoing colectomy with primary colorectal or coloanal anastomosis and studies that assessed the postoperative results. The protocol is registered in PROSPERO (No. CRD42021267715).
Results
Eleven articles met the eligibility criteria and were selected. The studied population size ranged from 7 to 78 patients. The overall mortality rate was 0% (95% confidence interval [CI], 0%–0.01%). The postoperative complication rate was 40% (95% CI, 40%–50%). The length of hospital stay was 13.68 days (95% CI, 11.3–16.06 days). After redo surgery, 82% of the patients were free of stoma (95% CI, 75%–90%), and 24% of patients (95% CI, 0%–39%) had fecal incontinence. Neoadjuvant chemoradiotherapy (P=0.002) was associated with a lower probability of being free of stoma in meta-regression.
Conclusion
Redo colorectal and coloanal anastomoses are strategies to restore colonic continuity. The decision to perform a redo operation should be based on a proper evaluation of the morbidity and mortality risks, the probability of remaining free of stoma, the quality of life, and a functional assessment.

Abstract PDF: Colitis caused by vasculitis is a rare and poorly understood pathology. Little evidence exists on its clinical presentation, path to diagnosis, and surgical management. In this report, we present a case report and literature review. A healthy 20-year-old male patient presented with hemorrhagic colitis requiring total colectomy with end ileostomy. Pathological examination showed pancolitis with multiple ulcers, transmural inflammation, hemorrhage, and microvascular thrombosis. Extensive serological testing revealed elevated cytoplasmic antineutrophil cytoplasmic antibody (c-ANCA) and eosinophilia, leading to a diagnosis of eosinophilic granulomatosis with polyangiitis (EGPA) and vasculitis-induced colitis. A literature review was subsequently conducted. Nineteen studies were found documenting vasculitis-induced colitis in the absence of inflammatory bowel disease (IBD). Systemic signs of vasculitis, hemorrhagic colitis, and progression to fulminant colitis were present. Of all patients, 40.0% required colorectal surgery and 62.5% of those patients received a stoma; 25% underwent emergency surgery following failed immunosuppression. All cases relied on clinical correlation with serology and/or histopathology to reach a final diagnosis. We report a case of vasculitis-induced colitis caused by c-ANCA−positive EGPA. The review shows that vasculitis-induced colitis without IBD is an important differential that clinicians should be aware of in patients presenting with colitis.

Abstract PDF: Purpose
Retrorectal tumors (RTs) are rare tumors that arise in the space between the mesorectum and the pelvic wall and often originate in embryonic tissues. The primary treatment for these tumors is complete excision surgery, and choosing the best surgical approach is very important.
Methods
In this study, we retrospectively collected the data of 15 patients with RTs who underwent surgery in Imam Khomeini Hospital (Tehran, Iran) for 12 years to share our experiences of patients’ treatment and compare different surgical approaches.
Results
A total of 5 tumors were malignant, 10 were benign, and most of the tumors were congenital. Malignant tumors were seen in older patients. Three surgical procedures were performed on patients. Three patients underwent abdominal approach surgery, and 8 patients underwent posterior surgery. A combined surgical approach was performed on 4 patients. Two patients underwent laparoscopic surgery. The abdominal approach had the least long-term complication, and the combined approach had the most complications; laparoscopic surgery reduced the length of hospital stay and complications after surgery.
Conclusion
A multidisciplinary team collaboration using magnetic resonance imaging details is necessary to determine a surgical treatment approach. It could reduce the need for a preoperative biopsy. However, every approach has its advantages and disadvantages, and individualized treatment is the key.

Abstract PDF

Purpose
Hemorrhoids are the most common benign anorectal diseases. Mucopexy strengthens the anal canal mucosa, which can be performed alone or in combination with Doppler-guided hemorrhoidal artery ligation (DG-HAL). In this study, we compared the postoperative complications between simple mucopexy plus HAL with and without a Doppler guide.
Methods
This study was performed as a single-blinded randomized clinical trial. Patients referred to a tertiary colorectal referral clinic with grades 3 and 4 hemorrhoids who were candidates for surgical intervention entered the study. Thirty-six patients were randomly divided into 2 groups. Group A including 18 patients underwent mucopexy and DG-HAL and the other 18 patients (group B) underwent standard mucopexy and HAL without a Doppler guide. Postoperative pain score and the duration of oral analgesic consumption were recorded. Additionally, postoperative symptoms and complications were recorded and compared between the 2 methods.
Results
There was no significant difference between the 2 groups in terms of pain score and the duration of postoperative analgesic consumption as well as the incidence of postoperative complications. Besides, the primary grade of hemorrhoids was not significantly associated with recurrence, but there was a significant association between body mass index and Wexner score (WS) with recurrence. The mean WS of patients showed a significant decrease in both groups postoperatively. However, the rate of WS reduction was not remarkably different between the 2 groups.
Conclusion
Simple mucopexy with blind HAL (without Doppler guide) might be considered for the treatment of grades 3 and 4 hemorrhoids effectively.

Purpose
This study was performed to investigate the convergent validity, discriminative validity, and reliability of the Brazilian version of the low anterior resection syndrome (LARS) score in a population with low educational and socioeconomic levels.
Methods
The LARS score was translated into the Portuguese language by forward- and back-translation procedures. In total, 127 patients from a public hospital in Brazil completed the questionnaires. The convergent validity was tested by comparing the LARS score with the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core Module 30 (QLQ-C30) and with patients’ self-reported quality of life. For the discriminative validity, we tested the ability of the score to differentiate among subgroups of patients regarding neoadjuvant radiotherapy, type of surgery, and tumor distance from the anal verge. The test-retest reliability was investigated in a subgroup of 36 patients who responded to the survey twice in 2 weeks.
Results
The LARS score demonstrated a strong correlation with 5 of 6 items from the EORTC QLQ-C30 (P<0.05) and good concordance with patients’ self-reported quality of life (95.3%), confirming the convergent validity. The score was able to discriminate between subgroups of patients with different clinical characteristics related to LARS (P<0.001). The agreement between the test and retest showed that 86.1% of the patients remained in the same LARS category, and there was no significant difference between the LARS score numerical values (P=0.80), indicating good reliability overall.
Conclusion
The Brazilian version of the LARS score is a valid and reliable instrument to assess postoperative bowel function in a population with low educational and socioeconomic levels.

Purpose
We aimed to investigate the difference in the surgical outcome based on whether the assistant overcame the mirror image in laparoscopic colorectal surgery.
Methods
Three hundred patients who underwent laparoscopic colorectal surgery performed by single operator were divided into 2 groups. Based on the assistants’ experience, patients who underwent surgery involving 1 of 6 residents with an experience of fewer than 30 surgeries each were classified into group 1. Patients who underwent surgery involving a single fellow as an assistant with an experience of over 1,000 surgeries were classified into group 2. According to the type of surgery, patients were divided into left and right colon resection groups and the surgical outcome of groups 1 and 2 was investigated.
Results
Group 2 exhibited shorter operation time, less bleeding, shorter postoperative hospital stay, lower open conversion, and anastomotic leakage rate than group 1. In right colon resection, the operation time was shorter in group 2. In left colon resection, group 2 exhibited shorter operation time, less bleeding, shorter postoperative hospital stay, and lower anastomotic leakage rate. In the multivariate analysis, the assistant was a factor affecting the operation time in the entire surgery.
Conclusion
Assistants’ reverse alignment surgical skill proficiency was a factor affecting the operation time.

Abstract PDF

Purpose
Anastomotic bleeding after colorectal surgery is a rare, mostly self-limiting, postoperative complication that could lead to a life-threatening condition. Therefore, prompt management is required. This study aimed to evaluate the efficacy and safety of endoscopic clipping for acute anastomotic bleeding after colorectal surgery.
Methods
We retrospectively reviewed the data of patients pathologically diagnosed with colorectal cancer at National Cancer Center, Korea from January 2018 to November 2020, which presented with anastomotic bleeding within the first postoperative week and were endoscopically managed with clips.
Results
Nine patients had anastomotic bleeding, underwent endoscopic management, and, therefore, were included in this study. All patients underwent laparoscopic (low/ultralow) anterior resection with mechanical double-stapled anastomosis. Anastomotic bleeding was successfully managed through a colonoscopy with clips on the first trial in all patients. Hypovolemic shock occurred in one patient, following anastomotic breakdown.
Conclusion
Endoscopic clipping seems to be an effective and safe treatment for anastomotic bleeding with minimal physiologic stress, easy accessibility, and scarce postoperative complications. However, a surgical backup should always be considered for massive bleeding.
