Abstract
BACKGROUND Creation of a tension-free colorectal anastomosis after left colon resection or low anterior resection is a key requirement for technical success. The relative contribution of each of a series of known lengthening maneuvers remains incompletely characterized. OBJECTIVE The aim of this study was to compare technical procedures for lengthening of the left colon before rectal anastomosis. DESIGN A series of lengthening maneuvers was performed on 15 fresh cadavers. Mean distance gained was measured for each successive maneuver, including 1) high inferior mesenteric artery ligation, 2) splenic flexure takedown, and 3) high inferior mesenteric vein ligation by the ligament of Treitz. SETTING Cadaveric study. MAIN OUTCOME MEASURES The premobilization and postmobilization position of the proximal colonic end was measured relative to the inferior edge of the sacral promontory. Measurements of the colonic length relative to the sacral promontory were taken after each mobilization maneuver. The inferior mesenteric artery, sigmoid colon, and rectum specimen lengths were measured. The distance from the inferior border of the sacral promontory to the pelvic floor was measured along the sacral curvature. RESULTS Mean sigmoid colon resection length was 34.7 ± 11.1 cm. Before any lengthening, baseline reach was -1.3 ± 4.2 cm from the sacral promontory. Inferior mesenteric artery ligation yielded an additional 11.5 ± 4.7 cm. Subsequent splenic flexure takedown added an additional 12.8 ± 9.6 cm. Finally, inferior mesenteric vein ligation added an additional 11.33 ± 6.9 cm, bringing the total colonic length to 35.7 ± 14.7 cm. BMI and weight negatively correlated with length gained. LIMITATIONS The study was limited by nature of being a cadaver study. CONCLUSIONS Stepwise lengthening maneuvers allow significant additional reach to allow a tension-free left colon to rectal anastomosis. See Video Abstract .

Abstract
A surgeon must possess the knowledge and technical skill to obtain length following a left-sided colorectal resection to perform a tension free anastomosis. The distal target organ - either rectum or anus - is fixed in location, and therefore requires surgeons to acquire mastery of proximal mobilization of the colonic conduit. Generally, splenic flexure mobilization (SFM) provides adequate length. Surgeons benefit from clearer understanding of the multiple steps involved in SFM as a result of improved visualization and demonstration of the relevant anatomy - adjacent organs and the attachments, embryologic planes, and mesenteric structures. Much may be attributed to laparoscopic and robotic platforms which provided improved exposure and as a result, development or refinement of novel approaches for SFM with potential advantages. Complete mobilization draws upon the sum or combination of the varied approaches to accomplish the goal. However, in the situation where extended resection is necessary or in the case of re-operative surgery sacrificing either more proximal or distal large intestine often occurs, the transverse colon or even the ascending colon represents the proximal conduit for anastomosis. This challenging situation requires familiarity with special maneuvers to achieve colorectal or coloanal anastomosis using these more proximal conduits. In such instances, operative techniques such as either ileal mesenteric window with retroileal anastomosis or de-rotation of the right colon (Deloyer's procedure) enable the intestinal surgeon to construct such anastomoses and thereby avoid stoma creation or loss of additional large intestine.

Abstract
Oncological adequacy in rectal cancer surgery mandates not only a clear distal and circumferential resection margin but also resection of the entire ontogenetic mesorectal package. Incomplete removal of the mesentery is one of the commonest causes of local recurrences. The completeness of the resection is not only determined by tumor and patient related factors but also by the patient-tailored treatment selected by the multidisciplinary team. This is performed in the context of the technical ability and experience of the surgeon to ensure an optimal total mesorectal excision (TME). In TME, popularized by Professor Heald in the early 1980s as a sharp dissection through the avascular embryologic plane, the midline pedicle of tumor and mesorectum is separated from the surrounding, mostly paired structures of the retroperitoneum. Although TME significantly improved the oncological and functional results of rectal cancer surgery, the difficulty of the procedure is still mainly dependent on and determined by the dissection of the most distal part of the rectum and mesorectum. To overcome some of the limitations of working in the narrowest part of the pelvis, robotic and transanal surgery have been shown to improve the access and quality of resection in minimally invasive techniques. Whatever technique is chosen to perform a TME, embryologically derived planes and anatomical points of reference should be identified to guide the surgery. Standardization of the chosen technique, widespread education, and training of surgeons, as well as caseloads per surgeon, are important factors to optimize outcomes. In this article, we discuss the introduction of transanal TME, with emphasis on the mesentery, relevant anatomy, standard procedural steps, and importance of a training pathway.

Abstract
OBJECTIVE To evaluate safety and effectiveness of routine splenic flexure mobilization (SFM) in surgical treatment of rectal cancer (RC). MATERIAL AND METHODS A single-center randomized study was performed between 2016 and 2019. Patients were randomized into 2 groups (SFM (+), n=156, SFM(-), n=67). Standard anterior and low anterior rectal resection was used. We used a combination of medial, lateral, and anterior approaches for SFM. Intraoperative, early and late postoperative complications, histological data, local recurrence, overall 3-year, relapse-free and cancer-specific survival were analyzed. RESULTS Surgery time was 253.2±72.8 and 252.0±78.0 min in the SFM(+) and SFM(-) groups, respectively (p=0.98). Blood loss was 53.3±53.6 and 67.0±108.8 ml, respectively (p=0.85), length of specimen - 28.6 (95% CI 27.2-29.9) and 24.0 cm (95% CI 22.2-25.7) (p<0.0001). Length of residual fragment of sigmoid colon was 5.0 (95% CI 3.9-6.1) and 9.1 cm (95% CI 7.2-11.1) (p<0.0001), respectively. The number of examined lymph nodes was 15.5 (95% CI 14.2-16.8) and 16.1 (95% CI 14.2-18.1) (p=0.52), number of affected lymph nodes - 1.5 (95% CI 0.9-2.1) and 1.5 (95% CI 0.9-2.2), respectively (p=0.38). Spleen damage was more common in the SFM (-) group (4.5% vs. 1.3%, p=0.12). Logistic regression analysis indicates that SFM does not affect the incidence of spleen damage. Severity of postoperative complications was similar (p=0.63). Anastomotic leak (AL) was more common in the SFM group (-) (17.9% vs. 9.6%, p=0.04). AL grade B was more common in the SFM(-) group (p=0.0001). Logistic regression analysis revealed the following predictors of anastomotic leakage: length of specimen and length of residual sigmoid colon. There was no significant relationship between SFM and incidence of local and systemic recurrences. Overall, cancer-specific and relapse-free 3-year survival was similar. CONCLUSION SFM is a safe procedure with various advantages. However, this approach does not improve intraoperative, early and long-term postoperative outcomes that does not allow us to recommend this approach for routine application.

Abstract
Natural infection with Plasmodium parasites, the causative agents of malaria, occurs via mosquito vectors. However, most of our knowledge of the immune response to the blood stages of Plasmodium is from infections initiated by injection of serially blood-passaged infected red blood cells, resulting in an incomplete life cycle in the mammalian host. Vector transmission of the rodent malaria parasite, Plasmodium chabaudi chabaudi AS has been shown to give rise to a more attenuated blood-stage infection in C57Bl/6J mice, when compared to infections initiated with serially blood-passaged P. chabaudi-infected red blood cells. In mouse models, the host immune response induced by parasites derived from natural mosquito transmission is likely to more closely resemble the immune responses to Plasmodium infections in humans. It is therefore important to determine how the host response differs between the two types of infections. As the spleen is considered to be a major contributor to the protective host response to P. chabaudi, we carried out a comparative transcriptomic analysis of the splenic response to recently mosquito-transmitted and serially blood-passaged parasites in C57Bl/6J mice. The attenuated infection arising from recently mosquito-transmitted parasites is characterised by an earlier and stronger myeloid- and IFNγ-related response. Analyses of spleen lysates from the two infections similarly showed stronger or earlier inflammatory cytokine and chemokine production in the recently mosquito-transmitted blood-stage infections. Furthermore, tissue macrophages, including red pulp macrophages, and IFNγ-signalling in myeloid cells, are required for the early control of P. chabaudi recently mosquito-transmitted parasites, thus contributing to the attenuation of mosquito-transmitted infections. The molecules responsible for this early activation response to recently-transmitted blood-stage parasites in mice would be important to identify, as they may help to elucidate the nature of the initial interactions between blood-stage parasites and the host immune system in naturally transmitted malaria. Attenuation of recently transmitted malaria happens at blood stage of infection. Stronger or earlier inflammatory cytokine and chemokine production. Tissue macrophages, including red pulp macrophages, contribute to attenuation. IFNγ-signalling in myeloid cells is required for early control of P. chabaudi AS.

Surgical anatomy of the accessory middle colic artery: a meta-analysis with implications for splenic flexure cancer surgery. Colorectal Dis 2021; 23:1712-1720. [PMID: 33721386 DOI: 10.1111/codi.15630] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/09/2020] [Revised: 11/16/2020] [Accepted: 03/07/2021] [Indexed: 12/12/2022]
Abstract
AIM Surgical resection of splenic flexure cancers (SFCs) is technically demanding due to the complex regional anatomy, characterized by the presence of embryological adhesions, close proximity to the pancreas and spleen, and a highly heterogeneous arterial supply and lymphatic drainage. The accessory middle colic artery (AMCA) is increasingly being recognized as an important source of blood supply to the splenic flexure. The aim of this study is to determine the prevalence and anatomical features of the AMCA. METHOD A systematic search of the scientific literature was conducted on PubMed and Embase from inception to November 2020 to identify potentially eligible studies. Data were extracted and prevalence was pooled into a meta-analysis using MetaXL and Meta-Analyst software. RESULTS A total of 16 studies (n = 2203 patients) were included. The pooled prevalence (PP) of the AMCA was 25.4% (95% CI 18.1-33.4). Its prevalence was higher in patients without a left colic artery (LCA) (PP = 83.2%; 95% CI 70.4-93.1). The commonest origin for the AMCA was the superior mesenteric artery (PP = 87.9%; 95% CI 86.4-90.7). The AMCA shared a common trunk/gave rise to pancreatic branches in 23.1% of cases (95% CI 15.3-31.9). CONCLUSION The AMCA contributes to the vascularization of the splenic flexure in approximately 25% of individuals, and may be an important feeder artery to SFCs, especially in the absence of a LCA. Preoperative identification of this artery is important to ensure optimal surgery for SFC and minimize complications.

Abstract
AIM The aim of this study was to evaluate the arterial collateral vasculature between the superior mesenteric artery and the inferior mesenteric artery (IMA) from a surgical perspective. METHOD A total of 107 fresh adult cadavers (94 male) were studied with emphasis on the vascular anatomy of the left colon. Dissections were carried out mimicking the anterior resection technique. The vasculature of the left mesocolon and the collaterals between the superior mesenteric artery and the IMA with respect to their relationship to the inferior mesenteric vein (IMV) were assessed and classified. Collaterals were classified into three different groups: marginal anastomoses (via the marginal = pericolic artery), intermediate mesocolic anastomoses (parallel to the marginal artery but neither adjacent to the IMV nor close to the duodenum) and central mesocolic anastomoses (next to the IMV at the level of the duodenojejunal junction and the lower border of the pancreas). RESULTS All patients had a marginal anastomosis. However, the marginal anastomosis, as the only anastomosis between the superior and inferior mesenteric arteries at the splenic flexure, was observed in 41 cases (38%). In addition to the marginal artery, intermediate mesocolic anastomoses were found in 49 (46%) and a central mesocolic anastomosis was observed in 17 (16%) of the 107 cases in the splenic flexure mesocolon. It is in this latter variant that collateral vessels can be compromised during ligation/transection of the IMV. CONCLUSION This new classification can contribute to a precise mesocolic dissection technique and splenic flexure mobilization and help prevent ischaemic damage to the descending colon.

Abstract
Background: Given the importance of operative documentation, we reviewed operative notes for surgeries that required splenic flexure mobilization (SFM) to determine their accuracy. Materials and Methods: We performed a retrospective review of 51 operative notes for complete SFMs performed at a single institution from January 2015 to June 2020. Results: None of the operative notes reported a rationale for performing SFM, use of preoperative imaging to guide technical approach, reasoning for the operative method and mobilization approach used, or specific steps taken to ensure that SFM was done safely. Most reports did not include technical details, with one-third of the notes merely reporting that "the splenic flexure was mobilized." Conclusions: Increased awareness about the lack of operative documentation of the critical aspects of the SFM could stimulate initiatives to standardize the SFM method and improve the quality of operative notes for SFM.

Abstract
Purpose: Laparoscopic rectal surgery has moved from being experimental to getting established as a mainstream procedure. We aimed at analysing how rectal cancer surgery has evolved at our institute. Methods: A retrospective review of 1000 consecutive patients who underwent laparoscopic anterior resection for rectal adenocarcinoma over a period of 15 years (January 2005 to December 2019) was performed. Technical modifications were made with splenic flexure mobilisation, intersphincteric dissection and anastomotic technique. The data collected included type of surgery, duration of surgery, conversion to open, anastomotic leak, defunctioning stoma and duration of hospital stay. The first 500 and the next 500 cases were compared. Results: The study patients were predominantly males comprising 68% (n = 680). The mean age of the patients was 58.3 years (range: 28–92 years). Majority of the procedures performed were high anterior resection (n = 402) and low anterior resection (LAR) (n = 341) followed by ultra-LAR (ULAR) (n = 208) and ULAR + colo-anal anastomosis (n = 49). A total of 42 patients who were planned for laparoscopic surgery needed conversion to open procedure. Forty-one patients (4.1%) had an anastomotic leak. The mean duration of stay was 5.3 + 2.8 days. The rate of conversion to open procedure had reduced from 5.4% to 3.0%. The rate of defunctioning stoma had reduced by >50% in the recent group. The anastomotic leak rate had reduced from 5.0% to 3.2%. The average duration of stay had reduced from 5.8 days to 4.9 days. Conclusion: This is one of the largest single-centre experiences of laparoscopic anterior resection. We have shown the progressive benefits of an evolving approach to laparoscopic anterior resection.

Abstract
For a disease process that affects so many, we continue to struggle to define optimal care for patients with diverticular disease. Part of this stems from the fact that diverticular disease requires different treatment strategies across the natural history- acute, chronic and recurrent. To understand where we are currently, it is worth understanding how treatment of diverticular disease has evolved. Diverticular disease was rarely described in the literature prior to the 1900’s. In the late 1960’s and early 1970’s, Painter and Burkitt popularized the theory that diverticulosis is a disease of Western civilization based on the observation that diverticulosis was rare in rural Africa but common in economically developed countries. Previous surgical guidelines focused on early operative intervention to avoid potential complicated episodes of recurrent complicated diverticulitis (e.g., with free perforation) that might necessitate emergent surgery and stoma formation. More recent data has challenged prior concerns about decreasing effectiveness of medical management with repeat episodes and the notion that the natural history of diverticulitis is progressive. It has also permitted more accurate grading of the severity of disease and permitted less invasive management options to attempt conversion of urgent operations into the elective setting, or even avoid an operation altogether. The role of diet in preventing diverticular disease has long been debated. A high fiber diet appears to decrease the likelihood of symptomatic diverticulitis. The myth of avoid eating nuts, corn, popcorn, and seeds to prevent episodes of diverticulitis has been debunked with modern data. Overall, the recommendations for “diverticulitis diets” mirror those made for overall healthy lifestyle – high fiber, with a focus on whole grains, fruits and vegetables. Diverticulosis is one of the most common incidental findings on colonoscopy and the eighth most common outpatient diagnosis in the United States. Over 50% of people over the age of 60 and over 60% of people over age 80 have colonic diverticula. Of those with diverticulosis, the lifetime risk of developing diverticulitis is estimated at 10–25%, although more recent studies estimate a 5% rate of progression to diverticulitis. Diverticulitis accounts for an estimated 371,000 emergency department visits and 200,000 inpatient admissions per year with annual cost of 2.1–2.6 billion dollars per year in the United States. The estimated total medical expenditure (inpatient and outpatient) for diverticulosis and diverticulitis in 2015 was over 5.4 billion dollars. The incidence of diverticulitis is increasing. Besides increasing age, other risk factors for diverticular disease include use of NSAIDS, aspirin, steroids, opioids, smoking and sedentary lifestyle. Diverticula most commonly occur along the mesenteric side of the antimesenteric taeniae resulting in parallel rows. These spots are thought to be relatively weak as this is the location where vasa recta penetrate the muscle to supply the mucosa. The exact mechanism that leads to diverticulitis from diverticulosis is not definitively known. The most common presenting complaint is of left lower quadrant abdominal pain with symptoms of systemic unwellness including fever and malaise, however the presentation may vary widely. The gold standard cross-sectional imaging is multi-detector CT. It is minimally invasive and has sensitivity between 98% and specificity up to 99% for diagnosing acute diverticulitis. Uncomplicated acute diverticulitis may be safely managed as an out-patient in carefully selected patients. Hospitalization is usually necessary for patients with immunosuppression, intolerance to oral intake, signs of severe sepsis, lack of social support and increased comorbidities. The role of antibiotics has been questioned in a number of randomized controlled trials and it is likely that we will see more patients with uncomplicated disease treated with observation in the future Acute diverticulitis can be further sub classified into complicated and uncomplicated presentations. Uncomplicated diverticulitis is characterized by inflammation limited to colonic wall and surrounding tissue. The management of uncomplicated diverticulitis is changing. Use of antibiotics has been questioned as it appears that antibiotic use can be avoided in select groups of patients. Surgical intervention appears to improve patient’s quality of life. The decision to proceed with surgery is recommended in an individualized manner. Complicated diverticulitis is defined as diverticulitis associated with localized or generalized perforation, localized or distant abscess, fistula, stricture or obstruction. Abscesses can be treated with percutaneous drainage if the abscess is large enough. The optimal long-term strategy for patients who undergo successful non-operative management of their diverticular abscess remains controversial. There are clearly patients who would do well with an elective colectomy and a subset who could avoid an operation all together however, the challenge is appropriate risk-stratification and patient selection. Management of patients with perforation depends greatly on the presence of feculent or purulent peritonitis, the extent of contamination and hemodynamic status and associated comorbidities. Fistulas and strictures are almost always treated with segmental colectomy. After an episode of acute diverticulitis, routine colonoscopy has been recommended by a number of societies to exclude the presence of colorectal cancer or presence of alternative diagnosis like ischemic colitis or inflammatory bowel disease for the clinical presentation. Endoscopic evaluation of the colon is normally delayed by about 6 weeks from the acute episode to reduce the risk associated with colonoscopy. Further study has questioned the need for endoscopic evaluation for every patient with acute diverticulitis. Colonoscopy should be routinely performed after complicated diverticulitis cases, when the clinical presentation is atypical or if there are any diagnostic ambiguity, or patient has other indications for colonoscopy like rectal bleeding or is above 50 years of age without recent colonoscopy. For patients in whom elective colectomy is indicated, it is imperative to identify a wide range of modifiable patient co-morbidities. Every attempt should be made to improve a patient’s chance of successful surgery. This includes optimization of patient risk factors as well as tailoring the surgical approach and perioperative management. A positive outcome depends greatly on thoughtful attention to what makes a complicated patient “complicated”. Operative management remains complex and depends on multiple factors including patient age, comorbidities, nutritional state, severity of disease, and surgeon preference and experience. Importantly, the status of surgery, elective versus urgent or emergent operation, is pivotal in decision-making, and treatment algorithms are divergent based on the acuteness of surgery. Resection of diseased bowel to healthy proximal colon and rectal margins remains a fundamental principle of treatment although the operative approach may vary. For acute diverticulitis, a number of surgical approaches exist, including loop colostomy, sigmoidectomy with colostomy (Hartmann’s procedure) and sigmoidectomy with primary colorectal anastomosis. Overall, data suggest that primary anastomosis is preferable to a Hartman’s procedure in select patients with acute diverticulitis. Patients with hemodynamic instability, immunocompromised state, feculent peritonitis, severely edematous or ischemic bowel, or significant malnutrition are poor candidates. The decision to divert after colorectal anastomosis is at the discretion of the operating surgeon. Patient factors including severity of disease, tissue quality, and comorbidities should be considered. Technical considerations for elective cases include appropriate bowel preparation, the use of a laparoscopic approach, the decision to perform a primary anastomosis, and the selected use of ureteral stents. Management of the patient with an end colostomy after a Hartmann’s procedure for acute diverticulitis can be a challenging clinical scenario. Between 20 – 50% of patients treated with sigmoid resection and an end colostomy after an initial severe bout of diverticulitis will never be reversed to their normal anatomy. The reasons for high rates of permanent colostomies are multifactorial. The debate on the best timing for a colostomy takedown continues. Six months is generally chosen as the safest time to proceed when adhesions may be at their softest allowing for a more favorable dissection. The surgical approach will be a personal decision by the operating surgeon based on his or her experience. Colostomy takedown operations are challenging surgeries. The surgeon should anticipate and appropriately plan for a long and difficult operation. The patient should undergo a full antibiotic bowel preparation. Preoperative planning is critical; review the initial operative note and defining the anatomy prior to reversal. When a complex abdominal wall closure is necessary, consider consultation with a hernia specialist. Open surgery is the preferred surgical approach for the majority of colostomy takedown operations. Finally, consider ureteral catheters, diverting loop ileostomy, and be prepared for all anastomotic options in advance. Since its inception in the late 90’s, laparoscopic lavage has been recognized as a novel treatment modality in the management of complicated diverticulitis; specifically, Hinchey III (purulent) diverticulitis. Over the last decade, it has been the subject of several randomized controlled trials, retrospective studies, systematic reviews as well as cost-efficiency analyses. Despite being the subject of much debate and controversy, there is a clear role for laparoscopic lavage in the management of acute diverticulitis with the caveat that patient selection is key. Segmental colitis associated with diverticulitis (SCAD) is an inflammatory condition affecting the colon in segments that are also affected by diverticulosis, namely, the sigmoid colon. While SCAD is considered a separate clinical entity, it is frequently confused with diverticulitis or inflammatory bowel disease (IBD). SCAD affects approximately 1.4% of the general population and 1.15 to 11.4% of those with diverticulosis and most commonly affects those in their 6th decade of life. The exact pathogenesis of SCAD is unknown, but proposed mechanisms include mucosal redundancy and prolapse occurring in diverticular segments, fecal stasis, and localized ischemia. Most case of SCAD resolve with a high-fiber diet and antibiotics, with salicylates reserved for more severe cases. Relapse is uncommon and immunosuppression with steroids is rarely needed. A relapsing clinical course may suggest a diagnosis of IBD and treatment as such should be initiated. Surgery is extremely uncommon and reserved for severe refractory disease. While sigmoid colon involvement is considered the most common site of colonic diverticulitis in Western countries, diverticular disease can be problematic in other areas of the colon. In Asian countries, right-sided diverticulitis outnumbers the left. This difference seems to be secondary to dietary and genetic factors. Differential diagnosis might be difficult because of similarity with appendicitis. However accurate imaging studies allow a precise preoperative diagnosis and management planning. Transverse colonic diverticulitis is very rare accounting for less than 1% of colonic diverticulitis with a perforation rate that has been estimated to be even more rare. Rectal diverticula are mostly asymptomatic and diagnosed incidentally in the majority of patients and rarely require treatment. Giant colonic diverticula (GCD) is a rare presentation of diverticular disease of the colon and it is defined as an air-filled cystic diverticulum larger than 4 cm in diameter. The pathogenesis of GCD is not well defined. Overall, the management of diverticular disease depends greatly on patient, disease and surgeon factors. Only by tailoring treatment to the patient in front of us can we achieve optimal outcomes.

Abstract
BACKGROUND During cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC), surgeons are reluctant to perform unprotected pelvic anastomosis despite lack of supporting data. We analyzed pelvic anastomosis outcomes and factors that influence ostomy creation in CRS/HIPEC patients. METHODS A single-center, descriptive study of patients with rectal resection during CRS/HIPEC was conducted using a prospective database. Surgical variables were reviewed. Multinomial logistic regression of outcomes (end or protective ostomy) was performed with pre- and intraoperative factors as predictors. RESULTS Overall, 274 of 789 CRS/HIPEC patients underwent rectal resection, including 243 (89%) with pelvic anastomosis [232 (85%) without ostomy, 11 (4%) with protective ileostomy] and 31 (11%) with no anastomosis [16 (6%) with end colostomy, 15 (5%) with end ileostomy]. The median age was 57 and 29% (79) were male. Of 243 pelvic anastomosis patients, 3 (1.2%) had rectal anastomotic leaks, including 1 with a protective ileostomy. Other anastomotic leaks occurred in 3.6%. Overall, 13% had Clavien-Dindo complications ≥ IIIB and the readmission rate was 30%. Mortality at 30 days and 100 days was 0.4% and 2.2%, respectively. Male gender and primary rectal cancer were associated with protective ileostomy [odds ratio (OR) = 7.01, 95% CI: 1.6-31.5, p = 0.011, and OR = 16.4, 95% CI: 3-88.4, p = 0.001, respectively). Male gender and prior pelvic surgery were associated with end colostomy (OR = 13.9, 95% CI: 3.7-53, p < 0.0001, and OR = 17.2, 95% CI: 3.8-78.6, p < 0.0001). CONCLUSIONS Pelvic bowel reconstruction without protective or end ostomy during CRS/HIPEC is safe. Protective ileostomy is associated with male gender and primary rectal cancer. End colostomy is associated with male gender and prior pelvic surgery.

Abstract
AIM The aim of this study was to describe all the possible approaches for laparoscopic splenic flexure mobilization (SFM), each suitable for specific situations, and create an illustrated system to show SFM approaches in an easy and practical way to make it easy to learn and teach. METHODS Two different phases. First part: Cadaver-based study of the colonic splenic flexure anatomy. In order to demonstrate the different approaches, a balloon was placed through the colonic hepatic flexure in the lesser sac without sectioning any of the fixing ligaments of the splenic flexure. Second part: A real case series of laparoscopic SFM. RESULTS First part: 11 cadavers were dissected. Five potential approaches to SFM were found: anterior, trans-omentum, lateral, medial infra-mesocolic, and medial trans-mesocolic. The illustrative system developed was named: Splenic Flexure "Box"(SFBox). Second part: One of the types of SFM described in first part was used in five patients with colorectal cancer. Each laparoscopic approach to the splenic flexure was illustrated in a video accompanied by illustration aids delineating the access. CONCLUSION With the cadaver dissection and subsequent demonstration in real-life laparoscopic surgery, we have shown five types of laparoscopic splenic flexure mobilization. The Splenic Flexure "Box" is a useful way to learn and teach this surgical maneuver.

Abstract
Nowadays, the issue of splenic flexure mobilization (SFM) in anterior and low anterior rectal resection for rectal cancer is still debatable. This stage is important because dissection results tension-free anastomosis and excision of specimen of enough length with adequate number of harvested lymph nodes. However, literature review confirmed the absence of agreement regarding reduced incidence of colorectal anastomotic leakage and improved long-term oncologic outcomes after SFM. Opinion about selective approach to this procedure is becoming more common. Therefore, randomized trials are necessary to determine a need for routine SFM or indications for selective approach to SFM in anterior rectal resection for rectal cancer.

Abstract
BACKGROUND Despite a lack of supporting data, routine splenic flexure mobilization (SFM) during colectomy has been thought to reduce anastomotic leak (AL). We evaluated the impact of SFM on outcomes in distal colectomy. STUDY DESIGN The 2005-2016 NSQIP database identified 66,068 patients undergoing distal colectomy with anastomosis. Cohorts were stratified by addition of SFM. Postoperative outcomes were compared between groups. Regression analysis identified factors affecting odds of developing AL. RESULTS SFM was performed in 27,475 patients (41.6%). There was no difference in overall complications between cases with SFM and those without (p = 0.55). SFM had longer operative times (220 min vs. 184 min; p < 0.0001). SFM was not associated with any difference in AL rate (3.6% vs. 3.7%; p = 0.86). Factors most associated with AL were lack of oral antibiotic preparation (OR 1.93; p < 0.001), chemotherapy (OR 1.91; p < 0.001), and weight loss (OR 1.68; p = 0.0005). Operative indication and approach did not affect leak. CONCLUSIONS SFM in distal colectomy increased operative time without decreasing overall complications or AL. Routine splenic flexure mobilization may add risk without significant benefit.

[PMID: 28827909 DOI: 10.1007/s12262-017-1631-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2015] [Accepted: 03/31/2017] [Indexed: 12/16/2022] Open
Abstract
Laparoscopic colorectal surgery for cancer is nowadays routinely performed worldwide. After the introduction by Heald of total mesorectal excision for rectal cancer, also a complete mesocolic excision has been advocated as an essential surgical step to improve oncologic results in patients with colon cancer. The complete removal of mesocolon with high ligation of the main mesenteric arteries and veins and the mobilization of splenic flexure are well-known but still debated in western surgical society. The authors reviewed the literature and outlined the rationale and the results of splenic flexure mobilization and complete mesocolic excision in laparoscopic surgery for colorectal cancer.

Reddy SHS, Gupta V, Yadav TD, Singh G, Sahni D. Lengthening of left colon after rectal resection: What all is adequate? A prospective cohort study. Int J Surg 2016; 31:27-32. [PMID: 27233374 DOI: 10.1016/j.ijsu.2016.05.042] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2015] [Revised: 05/15/2016] [Accepted: 05/20/2016] [Indexed: 01/28/2023]
Abstract
BACKGROUND Adequate mobilization of colon is essential to achieve tension free anastomosis after sphinchter saving surgeries. METHODS 26 patients undergoing of recto-sigmoid resection underwent low tie of inferior mesenteric artery (IMA), splenic flexure mobilization and descending branch of left colic artery (LCA) ligation in that order. One point at proximal 1/3rd of sigmoid colon (point of partial sigmoid resection) and another at descending-sigmoid colon junction (point of total sigmoid resection) were used for measurements and the distance was measured from pubic symphysis. Mobilization was considered adequate if colon could reach 2 cm beyond the upper border of pubic symphysis. RESULTS The length gained after each maneuver was 4.2 + 3.6 cm (low tie), 5.8 + 3.7 cm (splenic flexure mobilization) and 4.7 + 4.2 cm (descending branch of LCA ligation). Mobilization was adequate in 19% and 0% (low tie), 56% and 20% (low tie with splenic flexure mobilization) and 100% and 86% (all three manoeuvres) with partial and complete sigmoid resection respectively. In 13 patients undergoing low anterior resection, adequate mobilization for anastomosis was attainable in 15.3% and 0% (low tie), 50% and 0% (low tie with splenic flexure mobilization) and 100% and 83.3% (all three manoeuvres) with partial and complete sigmoid resection respectively. 15.3% had anastomotic leak, however none of the patients undergoing descending branch of LCA ligation had anastomotic insufficiency. CONCLUSIONS Low tie of IMA, with splenic flexure mobilization as required results in sufficient mobilization only in 50% patients with partial sigmoid resection. Ligation of descending branch of LCA is feasible, safe and enables a tension free anastomosis and is especially beneficial when sigmoid colon is resected completely.

Lymph node retrieval for colorectal cancer: Estimation of the minimum resection length to achieve at least 12 lymph nodes for the pathological analysis. Int J Surg 2015; 25:153-7. [PMID: 26713777 DOI: 10.1016/j.ijsu.2015.12.062] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2015] [Accepted: 12/15/2015] [Indexed: 01/24/2023]
Abstract
INTRODUCTION Adequate lymph node retrieval is important in colorectal cancer staging for the selection of patients that necessitate adjuvant treatments. The minimum number of 12 lymph nodes is one of the premises and is dependent, among the other factors, from the length of bowel resected. We have reviewed our specimens to identify the high-risk operations for inadequate nodal sampling and estimate the minimum length of bowel needed to resect to achieve this purpose. MATERIALS AND METHODS A retrospective review of colorectal specimens over 10 years of activity looking at data including location of the tumor, type of operation performed, length of bowel resected and number of lymph nodes retrieved. RESULTS Abdominoperineal and Hartmann's resections produced significant lower adequate retrievals compared to other colorectal operations, corresponding to 45.4% and 59.1% of cases respectively. The measured average length of bowel was 30 cm and 25 cm respectively, increasing the length to 36 cm and 42 cm would increase the adequacy rate to 90%. CONCLUSIONS Abdominoperineal and Hartmann's resections are, in our series, high-risk operations that frequently do not produce the minimum number of lymph nodes necessary. These operations may require additional maneuvers such as mobilization of the splenic flexure to achieve the minimum length of bowel to resect.

Kye BH, Kim HJ, Kim HS, Kim JG, Cho HM. How much colonic redundancy could be obtained by splenic flexure mobilization in laparoscopic anterior or low anterior resection? Int J Med Sci 2014; 11:857-62. [PMID: 25013364 PMCID: PMC4081306 DOI: 10.7150/ijms.8874] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2014] [Accepted: 05/12/2014] [Indexed: 01/07/2023] Open
Abstract
BACKGROUND AND OBJECTIVES Splenic flexure mobilization (SFM) is performed to ensure a tension free anastomosis with an adequate resection margin in laparoscopic anterior resection (AR) or low anterior resection (LAR). This retrospective study was performed to determine the amount of colonic redundancy that can be expected by SFM. METHODS Retrospective review of medical record for a total of 203 patients who underwent SFM during laparoscopic AR or LAR for the treatment of sigmoid colon or rectal cancer was performed. RESULTS The obtained redundancy of the colon by SFM was 27.81 ± 7.29 cm from the sacral promontory. The redundancy of the colon by SFM with high ligation of the inferior mesenteric vein (IMV) (29.54 ± 7.17 cm from the sacral promontory) was greater than that with low ligation of the IMV (24.94 ± 6.07 cm from the sacral promontory, P < 0.0001). It took about 9.82% of the total operation time to perform SFM. There was no intraoperative complication during SFM. CONCLUSIONS SFM during laparoscopic AR or LAR is a safe and feasible option. Based on the result of this study, one can gain about 27.81 cm redundancy of the colon by SFM.
