Comparison of conventional resection to D3 lymphadenectomy in right-sided colon cancer: A retrospective cohort study. Am J Surg 2024; 237:115911.

Abstract
BACKGROUND Lymphadenectomy during right hemicolectomy for colon cancer varies between the U.S. and Japan. METHODS Patients undergoing right hemicolectomy for non-metastatic right-sided colon cancer between 2010 and 2019 at U.S. and Japanese institutions were compared. Outcomes included survival, pathologic findings, and postoperative complications. RESULTS 319 American patients (57 % female, mean age 70 years) underwent conventional resection and 308 Japanese patients (52 % female, mean age 70 years) underwent extended dissection. The conventional group underwent more laparotomies (26.6 % vs. 8.4 %, p < 0.001), had more poorly differentiated histology (31.7 % vs. 11.0 %, p < 0.01), lower lymph node yield (M = 27 ± 11 vs. M = 32 ± 14, p < 0.001), and more 30-day readmissions (31 vs. 5, p < 0.001). Adjusting for demographics, pathology, perioperative outcomes, and adjuvant chemotherapy, extended lymphadenectomy improved disease-free survival (HR 0.50; 95 % CI, 0.31-0.80; p = 0.004), but not overall survival (HR 0.98; 95 % CI, 0.95-1.02; p = 0.14). CONCLUSIONS Extended lymphadenectomy for right sided-colon cancer improves disease-free, but not overall, survival among Japanese patients.

Abstract
Since the early1990s, laparoscopic right colon resections have been the most performed advanced laparoscopic procedures just after laparoscopic left colectomies and sigmoid resections. Indications for laparoscopic right colectomies are either benign or malignant diseases. Despite its many indications, a laparoscopic right or extended right colectomy is mostly performed for cancer of the caecum, the ascending colon, the hepatic flexure or the proximal transverse colon. Worldwide, colorectal cancer is the third most diagnosed cancer: an estimated 1,880,725 people were diagnosed with colorectal cancer in 2020, out of which 1,148,515 were colon cancer cases and 40% were located in the right colon. These figures make an oncologic sound surgery for right colon cancer of the utmost relevance. More recently, complete mesocolic excision has been advocated as the optimal choice in term of radicality, especially in node-positive patients with right colon cancer. Laparoscopic standard right colectomy and extended right colectomy with or without CME should be performed according to defined principles based on a close knowledge of key anatomical landmarks. This knowledge will allow to trace anatomical structures and drive instruments along the correct surgical planes and has its foundations in teachings from surgeons and scientists of past and present time.

Gastrointestinal functions after laparoscopic right colectomy with intracorporeal anastomosis: a pilot randomized clinical trial on effects of abdominal drain, prolonged antibiotic prophylaxis, and D3 lymphadenectomy with complete mesocolic excision. Int J Colorectal Dis 2024; 39:102.

Abstract
PURPOSE Routine use of abdominal drain or prolonged antibiotic prophylaxis is no longer part of current clinical practice in colorectal surgery. Nevertheless, in patients undergoing laparoscopic right hemicolectomy with intracorporeal anastomosis (ICA), it may reduce perioperative abdominal contamination. Furthermore, in cancer patients, prolonged surgery with extensive dissection such as central vascular ligation and complete mesocolon excision with D3 lymphadenectomy (altogether radical right colectomy RRC) is called responsible for affecting postoperative ileus. The aim was to evaluate postoperative resumption of gastrointestinal functions in patients undergoing right hemicolectomy for cancer with ICA and standard D2 dissection or RRC, with or without abdominal drain and prolonged antibiotic prophylaxis. METHODS Monocentric factorial parallel arm randomized pilot trial including all consecutive patients undergoing laparoscopic right hemicolectomy and ICA for cancer, in 20 months. Patients were randomized on a 1:1:1 ratio to receive abdominal drain, prolonged antibiotic prophylaxis or neither (I level), and 1:1 to receive RRC or D2 colectomy (II level). Patients were not blinded. The primary aim was the resumption of gastrointestinal functions (time to first gas and stool, time to tolerated fluids and food). Secondary aims were length of stay and complications' rate. CLINICALTRIALS gov no. NCT04977882. RESULTS Fifty-seven patients were screened; according to sample size, 36 were randomized, 12 for each arm for postoperative management, and 18 for each arm according to surgical techniques. A difference in time to solid diet favored the group without drain or antibiotic independently from standard or RRC. Furthermore, when patients were divided with respect to surgical technique and into matched cohorts, no differences were seen for primary and secondary outcomes. CONCLUSION Abdominal drainage and prolonged antibiotic prophylaxis in patients undergoing right hemicolectomy for cancer with ICA seem to negatively affect the resumption of a solid diet after laparoscopic right hemicolectomy with ICA for cancer. RRC does not seem to influence gastrointestinal function recovery.

Long-term oncologic outcome of D3 lymph node dissection for clinical stage 2/3 right-sided colon cancer. Int J Colorectal Dis 2023; 38:42. [PMID: 36790520 DOI: 10.1007/s00384-023-04310-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 01/08/2023] [Indexed: 02/16/2023]
Abstract
PURPOSE To investigate oncologic outcomes including overall survival and disease-free survival depending on the extent of lymphadenectomy (D3 versus D2) by comparing D3 and D2 lymphadenectomy in patients with clinical stage 2/3 right colon cancer. METHODS Consecutive series of patients who underwent radical resection for right colon cancer at our three hospitals between January 2015 and June 2018 were retrospectively analyzed. Study cohorts were divided into two groups: D3 group and D2 group. Oncologic, pathologic, and perioperative outcomes of the two groups were compared. RESULTS A total of 295 patients (167 in the D2 group and 128 in the D3 group) were included in this study. Patients' characteristics showed no significant difference between the two groups. The median number of harvested lymph nodes was significantly higher in the D3 group than in the D2 group. The rate of complications was not significantly different between the two groups except for chyle leakage, which was more frequent in the D3 group. Five-year disease-free survival was 90.2% (95% CI: 84.8-95.9%) in the D3 group, which was significantly (p = 0.028) higher than that (80.5%, 95% CI: 74-87.5%) in the D2 group. There was no significant difference in overall survival between the two groups. CONCLUSION Our results indicate that D3 lymphadenectomy is associated with more favorable 5-year disease-free survival than D2 lymphadenectomy for patients with stage 2/3 right-sided colon cancer. D3 lymphadenectomy might improve oncologic outcomes in consideration of the recurrence rate.

Abstract
BACKGROUND Several procedures have been proposed to reduce the rates of recurrence in patients with right-sided colon cancer. Different procedures for a radical right colectomy (RRC), including extended D3 lymphadenectomy, complete mesocolic excision and central vascular ligation have been associated with survival benefits by some authors, but results are inconsistent. The aim of this study was to assess the variability in definition and reporting of RRC, which might be responsible for significant differences in outcome evaluation. METHODS PRISMA-compliant systematic literature review to identify the definitions of RRC. Primary aims were to identify surgical steps and different nomenclature for RRC. Secondary aims were description of heterogeneity and overlap among different RRC techniques. RESULTS Ninety-nine articles satisfied inclusion criteria. Eight surgical steps were identified and recorded as specific to RRC: Central arterial ligation was described in 100% of the included studies; preservation of mesocolic integrity in 73% and dissection along the SMV plane in 67%. Other surgical steps were inconstantly reported. Six differently named techniques for RRC have been identified. There were 35 definitions for the 6 techniques and 40% of these were used to identify more than one technique. CONCLUSIONS The only universally adopted surgical step for RRC is central arterial ligation. There is great heterogeneity and consistent overlap among definitions of all RRC techniques. This is likely to jeopardise the interpretation of the outcomes of studies on the topic. Consistent use of definitions and reporting of procedures are needed to obtain reliable conclusions in future trials. PROSPERO CRD42021241650.

Abstract
Introduction The mid-transverse colon cancer is relatively uncommon in all colon cancers and the optimal surgical approach of mid-transverse colon cancer remains debatable. Aim and Objectives Our study aimed to depict the techniques and outcomes of laparoscopic transverse colectomy in one single clinical center and compare this surgical approach to traditional laparoscopic right hemicolectomy and laparoscopic left hemicolectomy. Method This was a retrospective cohort study of patients with mid-transverse colon cancer in one single clinical center from February 2012 to October 2020. The enrolled patients were divided into two groups undergoing laparoscopic transverse colectomy and laparoscopic right/left hemicolectomy, respectively. The intraoperative, postoperative complications, oncological outcomes and functional outcomes were compared between the two groups. The primary endpoint was disease free survival (DFS). Results The study enrolled 70 patients with 40 patients undergoing laparoscopic transverse colectomy and 30 patients undergoing laparoscopic hemicolectomy. The intraoperative accidental hemorrhage and multiple organ resection occurred similarly in the two groups. In transverse colectomy, caudal-to-cephalic approach was likely to harvest more lymph nodes although require more operation time than cephalic-to-caudal approach (23.1 ± 14.3 vs. 13.4 ± 5.4 lymph nodes, P = 0.004; 184.3 ± 37.1 min vs. 146.3 ± 44.4 min, P = 0.012). The laparoscopic transverse colectomy was marginally associated with lower incidence of overall postoperative complications and shorter postoperative hospital stay although without statistical significance (8(20.0%) vs. 12(40.0%), P = 0.067; 7(5-12) vs. 7(5-18), P = 0.060). The 3-year DFS showed no significant difference (3-year DFS 89.7% in transverse colectomy vs. 89.9% in hemicolectomy, P = 0.688) between the two groups. The alternating consistency of defecation occurred significantly less after laparoscopic transverse colectomy than laparoscopic hemicolectomy (15(51.7%) vs. 20(80.0%), P = 0.030). Conclusion The laparoscopic transverse colectomy is technically feasible with satisfactory oncological and functional outcomes for mid-transverse colon cancer. Performing the caudal-to-cephalic approach might be more advantageous in lymphadenectomy.

Abstract
BACKGROUND Differences in long-term outcomes regarding types of colon resections are inconclusive, precluding patient counseling, effective screening, and personalized treatment. OBJECTIVE This study aimed to compare long-term bowel function and quality of life in patients who underwent right or left hemicolectomy or sigmoid colon resection. DESIGN This was a multicenter cross-sectional study. SETTINGS Seven Dutch hospitals participated in this study. PATIENTS This study included patients who underwent right or left hemicolectomy or sigmoid colon resection without construction of a permanent stoma between 2009 and 2015. Patients who were deceased, mentally impaired, or living abroad were excluded. Eligible patients were sent the validated Defecation and Fecal Continence and Short-Form 36 questionnaires. MAIN OUTCOME MEASURES Constipation, fecal incontinence (both Rome IV criteria), separate bowel symptoms, and generic quality of life were the main outcomes assessed. RESULTS This study included 673 patients who underwent right hemicolectomy, 167 who underwent left hemicolectomy, and 284 who underwent sigmoid colon resection. The median follow-up was 56 months. Sigmoid colon resection increased the likelihood of constipation compared to right and left hemicolectomy (OR, 2.92; 95% CI, 1.80-4.75; p < 0.001 and OR, 1.93; 95% CI, 1.12-3.35; p = 0.019). Liquid incontinence and fecal urgency increased after right hemicolectomy compared to sigmoid colon resection (OR, 2.15; 95% CI, 1.47-3.16; p < 0.001 and OR, 2.01; 95% CI, 1.47-2.74; p < 0.001). Scores on quality-of-life domains were found to be significantly lower after right hemicolectomy. LIMITATIONS Because of the cross-sectional design, longitudinal data are still lacking. CONCLUSIONS Different long-term bowel function problems occur after right or left hemicolectomy or sigmoid colon resection. The latter seems to be associated with more constipation than right or left hemicolectomy. Liquid incontinence and fecal urgency seem to be associated with right hemicolectomy, which may explain the decline in physical and mental generic quality of life of these patients.

A los pacientes elegibles se les enviaron los cuestionarios validados de Defecación y Continencia Fecal y Short-Form 36.PRINCIPALES MEDIDAS DE RESULTADO:Se evaluaron el estreñimiento, la incontinencia fecal (ambos criterios de Roma IV), los síntomas intestinales separados y la calidad de vida genérica.RESULTADOS:Se incluyeron 673 pacientes con hemicolectomía derecha, 167 con hemicolectomía izquierda y 284 con resección de colon sigmoide. La mediana de seguimiento fue de 56 meses (RIC 41-80). La resección del colon sigmoide aumentó la probabilidad de estreñimiento en comparación con la hemicolectomía derecha e izquierda (OR, 2,92, IC 95%, 1,80-4,75, p < 0,001 y OR 1,93, IC 95%, 1,12-3,35, p = 0,019). La incontinencia de líquidos y la urgencia fecal aumentaron después de la hemicolectomía derecha en comparación con la resección del colon sigmoide (OR, 2,15, IC 95%, 1,47-3,16, p < 0,001 y OR 2,01, IC 95%, 1,47-2,74, p < 0,001). Las puntuaciones en los dominios de calidad de vida fueron significativamente más bajas después de la hemicolectomía derecha.LIMITACIONES:Debido al diseño transversal, aún faltan datos longitudinales.CONCLUSIONES:Se producen diferentes problemas de función intestinal a largo plazo después de la hemicolectomía derecha o izquierda, o la resección del colon sigmoide. Este último parece estar asociado con más estreñimiento que la hemicolectomía derecha o izquierda. La incontinencia de líquidos y la urgencia fecal parecen estar asociadas a la hemicolectomía derecha, lo que puede explicar el deterioro de la calidad de vida física y mental en general de estos pacientes.

Reconstructing topography and extent of injury to the superior mesenteric artery plexus in right colectomy with extended D3 mesenterectomy: a composite multimodal 3-dimensional analysis. Surg Endosc 2022; 36:7607-7618. [PMID: 35380284 PMCID: PMC9485098 DOI: 10.1007/s00464-022-09200-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2021] [Accepted: 03/17/2022] [Indexed: 02/08/2023]
Abstract
Abstract
Background
Superior mesenteric artery plexus (SMAP) injury is reported to cause postoperative intractable diarrhea after pancreatic/colonic surgery with extended lymphadenectomy. This study aims to describe the SMAP microanatomy and extent of injury after right colectomy with extended D3 mesenterectomy for cancer.
Methods
Three groups (I) anatomical dissection, (II) postmortem histology, and (III) surgical specimen histology were included. Nerve count and area were compared between groups II and III and paravascular sheath thickness between groups I and II. 3D models were generated through 3D histology, nanoCT scanning, and finally through 3D printing.
Results
A total of 21 specimens were included as follows: Group (I): 5 (3 females, 80–93 years), the SMAP is a complex mesh surrounding the superior mesenteric artery (SMA), branching out, following peripheral arteries and intertwining between them, (II): 7 (5 females, 71–86 years), nerve count: 53 ± 12.42 (38–68), and area: 1.84 ± 0.50 mm2 (1.16–2.29), and (III): 9 (5 females, 55–69 years), nerve count: 31.6 ± 6.74 (range 23–43), and area: 0.889 ± 0.45 mm2 (range 0.479–1.668). SMAP transection injury is 59% of nerve count and 48% of nerve area at middle colic artery origin level. The median values of paravascular sheath thickness decreased caudally from 2.05 to 1.04 mm (anatomical dissection) and from 2.65 to 1.17 mm (postmortem histology). 3D histology models present nerve fibers exclusively within the paravascular sheath, and lymph nodes were observed only outside. NanoCT-derived models reveal oblique nerve fiber trajectories with inclinations between 35° and 55°. Two 3D-printed models of the SMAP were also achieved in a 1:2 scale.
Conclusion
SMAP surrounds the SMA and branches within the paravascular sheath, while bowel lymph nodes and vessels lie outside. Extent of SMAP injury on histological slides (transection only) was 48% nerve area and 59% nerve count. The 35°–55° inclination range of SMAP nerves possibly imply an even larger injury when plexus excision is performed (lymphadenectomy). Reasons for later improvement of bowel function in these patients can lie in the interarterial nerve fibers between SMA branches.

Abstract
BACKGROUND Preoperative planning is a crucial aspect of safe complete mesocolic excision (CME) surgery. 3D models derived from imaging may help improve anatomical understanding of the complex vascular anatomy. Here, we assessed the effect of 3D models on surgeons' anatomical understanding in comparison to a systematic approach for CT scan interpretation (AMIGO). METHOD Fifteen cases were included in the study. Two GI radiology consultants reviewed each scan to ascertain the vascular anatomy. Virtual 3D models were produced and displayed on a web-based platform (https://skfb.ly/6OZUZ). A total of 13 surgical trainees were recruited. Candidates were assessed after baseline anatomical training and subsequently using the AMIGO method and 3D models. Five cases were randomly allocated in each round of testing for each participant. The primary outcome measure was an objective vascular anatomy knowledge score. The secondary outcome measure was subjective feedback from participants. RESULTS Both 3D and AMIGO significantly improved anatomical understanding in comparison to baseline testing. However, 3D was superior to AMIGO (3D [n = 65; median score 8/14] vs. AMIGO [n = 65; median score 6/14; p < 0.0001]. For 13/15 patient cases examined, 3D was superior to the AMIGO method. Eleven participants demonstrated better anatomical understanding using 3D models versus AMIGO. Ten participants preferred 3D models in comparison to standard CT imaging. CONCLUSIONS 3D models improve anatomical understanding of mesenteric vascular anatomy in a group of colorectal surgical trainees in comparison to a formal CT interpretation method. 3D models may be a useful planning adjunct to 2D imaging for CME surgery.

Long-Term Outcome of Patients with Postoperative Refractory Diarrhea After Tailored Nerve Plexus Dissection Around the Major Visceral Arteries During Pancreatoduodenectomy for Pancreatic Cancer. World J Surg 2022; 46:1172-1182.

Abstract
BACKGROUND For pancreatic ductal adenocarcinoma (PDAC) surgery, extended dissection of the nerve plexus (pl) around the superior mesenteric artery (SMA) or celiac artery (CA) is sometimes necessary. This consequently results in postoperative refractory diarrhea. This study aimed to evaluate the clinical impact of extended nerve plexus dissection around major arteries on postoperative diarrhea. METHODS Patients who underwent pancreatoduodenectomy (PD) for PDAC between January 2013 and December 2016 were included. The frequency of diarrhea (defined as a condition requiring opioid antidiarrheal drug for at least 6 months after surgery) and its short- and long-term outcomes were reviewed. RESULTS Of 200 consecutive patients who underwent PD, 78 (39.0%) developed postoperative refractory diarrhea (diarrhea group), and 73 of them (93.6%) underwent hemi-circumferential or more nerve dissection for SMA or CA; both plSMA and plCA dissection were associated with diarrhea. Borderline resectable artery (BR-A) PDAC was included more in the diarrhea group (32.0% vs. 13.1%, P = 0.001); however, the local recurrence rate in the diarrhea group was significantly lower than that in the non-diarrhea group (14.1% vs. 26.2%, P = 0.036). The completion of adjuvant chemotherapy and overall survival were comparable between the two groups. The pre-albumin level improved in 2 years, and 61.3% of patients with diarrhea could stop opioid antidiarrheal drugs within 3 years of surgery. CONCLUSIONS Although the frequency of diarrhea increased following nerve plexus dissection around arteries, diarrhea was controllable and resulted in a reduced local recurrence rate. Aggressive dissection of the nerve plexus may be justified for local disease control in BR-A PDAC.

Abstract
PURPOSE D3 lymphadenectomy for right colon cancer improves oncological outcomes. This meta-analysis aimed to compare operation data, histopathological characteristics, perioperative conditions, and long-term survival after D3 and D2 lymphadenectomy in right hemicolectomy. METHODS We searched PubMed, Embase, and the Cochrane Library for relevant articles (up to March 31, 2020). Random-effects and fixed-effects meta-analysis models were used. Review Manager (RevMan) version 5.3 and Stata version 15.1 were used for pooled estimates. RESULTS After screening 714 articles, 7 articles with a total of 1368 patients were eligible for inclusion. Compared with D2, D3 lymphadenectomy improves results in terms of blood loss (weighted mean difference [WMD] = -20.63, 95% confidence interval [CI] -28.19 to -13.16, P < .01), harvested lymph nodes (WMD = 8.86, 95% CI 7.74 to 9.98, P < .01), 3-year overall survival (OS) (hazard ratio [HR] = 2.03, 95% CI 1.20 to 3.43, P < .01), 5-year OS (HR = 2.22, 95% CI 1.15 to 4.30, P = .02), and 5-year disease-free survival (DFS) (HR = 2.16, 95% CI 1.19 to 3.90, P = .01). There was no significant difference regarding operation time, anastomosis leakage, wound infection, overall morbidity, postoperative hospital stay, mortality, length of dissected colon, and 3-year DFS (P >= .05). CONCLUSIONS It is suggested in this review that D3 lymphadenectomy is superior to D2 lymphadenectomy in terms of blood loss, harvested lymph nodes, 3-year OS, 5-year OS, and 5-year DFS. The conclusion must be drawn with caution due to the limited number of included studies. Further RCTs are needed for stronger evidence.

Abstract
Colon cancer treatment is on the way to evolution over several decades. The minimally invasive surgery has improved postoperative short-term outcomes. Adjuvant chemotherapy has prolonged the survival of advanced colon cancer patients. Hohenberger proposed the noble concept of complete mesocolic excision (CME) which consists of 3 components: plane surgery, sufficient longitudinal bowel resection, and central vascular ligation (CVL). Mesocolic plane surgery shares the same surgical principle of total mesorectal excision, which is maintaining the intact mesothelial envelope. However, there remain debates about the extent of bowel resection and the level of CVL for maximizing lymph node dissection. There is no solid clinical evidence for the oncological necessity and benefit of extended radical dissection in right hemicolectomy. CME with CVL based on open surgery has been adopted in laparoscopic surgery. So, it is also necessary to look at how the CME could be transformed and successfully implanted in the laparoscopic era. Recent rapid advances in surgical technology and cancer biology are preparing for fundamental changes in cancer surgery. In this study, we reviewed the history, oncological necessity, and compatibility of CME for the right hemicolectomy in the laparoscopic era and outline the new perspectives on the evolution of cancer surgery.

Right hemicolectomy with complete mesocolic excision is safe, leads to an increased lymph node yield and to increased survival: results of a systematic review and meta-analysis. Tech Coloproctol 2021; 25:1099-1113. [PMID: 34120270 PMCID: PMC8419145 DOI: 10.1007/s10151-021-02471-2] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Accepted: 05/30/2021] [Indexed: 01/04/2023]
Abstract
BACKGROUND The introduction of complete mesocolic excision (CME) for right colon cancer has raised an important discussion in relation to the extent of colic and mesenteric resection, and the impact this may have on lymph node yield. As uncertainty remains regarding the usefulness of and indications for right hemicolectomy with CME and the benefits of CME compared with a traditional approach, the purpose of this meta-analysis is to compare the two procedures in terms of safety, lymph node yield and oncological outcome. METHODS We performed a systematic review of the literature from 2009 up to March 15th, 2020 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Two hundred eighty-one publications were evaluated, and 17 met the inclusion criteria and were included. Primary endpoints analysed were anastomotic leak rate, blood loss, number of harvested lymph nodes, 3- and 5-year oncologic outcomes. Secondary outcomes were operating time, conversion, intraoperative complications, reoperation rate, overall and Clavien-Dindo grade 3-4 postoperative complications. RESULTS In terms of safety, right hemicolectomy with CME is not inferior to the standard procedure when comparing rates of anastomotic leak (RR 0.82, 95% CI 0.38-1.79), blood loss (MD -32.48, 95% CI -98.54 to -33.58), overall postoperative complications (RR 0.82, 95% CI 0.67-1.00), Clavien-Dindo grade III-IV postoperative complications (RR 1.36, 95% CI 0.82-2.28) and reoperation rate (RR 0.65, 95% CI 0.26-1.75). Traditional surgery is associated with a shorter operating time (MD 16.43, 95% CI 4.27-28.60) and lower conversion from laparoscopic to open approach (RR 1.72, 95% CI 1.00-2.96). In terms of oncologic outcomes, right hemicolectomy with CME leads to a higher lymph node yield than traditional surgery (MD 7.05, 95% CI 4.06-10.04). Results of statistical analysis comparing 3-year overall survival and 5-year disease-free survival were better in the CME group, RR 0.42, 95% CI 0.27-0.66 and RR 0.36, 95% CI 0.17-0.56, respectively. CONCLUSIONS Right hemicolectomy with CME is not inferior to traditional surgery in terms of safety and has a greater lymph node yield when compared with traditional surgery. Moreover, right-sided CME is associated with better overall and disease-free survival.

Abstract
BACKGROUND Opinions vary on the medial border of D3 lymphadenectomy for right colon cancer. Most surgeons place the medial border along the left side of the superior mesenteric vein, but some consider the left side of the superior mesenteric artery as the medial border. OBJECTIVES This study investigated the clinical outcomes of laparoscopic D3 lymphadenectomy for right colon cancer with the medial border along the left side of superior mesenteric artery. DESIGN This was a retrospective study. SETTINGS The study was conducted in specialized colorectal cancer department of 5 tertiary hospitals. PATIENTS Patients receiving laparoscopic D3 lymphadenectomy for right colon cancer from January 2013 to December 2018 were included. MAIN OUTCOME MEASURES After propensity score matching, 307 patients receiving laparoscopic D3 lymphadenectomy along the left side of the superior mesenteric artery were assigned to the superior mesenteric artery group and 614 patients were assigned to the superior mesenteric vein group. Univariate, multivariate, and Kaplan-Meier analyses were performed to assess the clinical data. RESULTS The short-term outcomes were similar between the 2 groups; however, the superior mesenteric artery group had a higher rate of chylous leakage (p < 0.001). More lymph nodes were harvested from the superior mesenteric artery group than from the superior mesenteric vein group (p = 0.001). The number (p = 0.005) of metastatic lymph nodes and the lymph node ratio (p = 0.041) in main nodes were both higher in the superior mesenteric artery group. The 2 groups had similar long-term survival, but the superior mesenteric artery group tended to show better disease-free survival in patients with stage disease III (p = 0.056). LIMITATIONS This was a retrospective, nonrandomized study. CONCLUSION Laparoscopic D3 lymphadenectomy along the left side of the superior mesenteric artery, except for a higher rate of chylous leakage, had short-term outcomes comparable to the superior mesenteric vein group. The superior mesenteric artery group tended to achieve better disease-free survival in patients with stage III disease, but further study is required to better elucidate differences in these approaches because risks/benefits do exist.

Abstract
OBJECTIVE The aim of this prospective clinical study is to compare short-term outcome of laparoscopic right hemicolectomy using the Complete Mesocolic Excision (CME group) with patients who underwent conventional right-sided colonic resection (NCME group). SUMMARY BACKGROUND DATA Although CME with central vascular ligation in laparoscopic right hemicolectomy is associated with a significant decrease in local recurrence rates and improvements in cancer-related 5-year survival, there may be additional risks associated with this technique because of increased surgical complications. As a result, there is controversy surrounding its use. METHODS In this randomized controlled trial, several primary endpoints (operative time, intraoperative blood loss, other complications, conversion rate, and anastomotic leak) and secondary endpoints (overall postoperative complications) were evaluated. In addition, we evaluated histopathologic data, including specimen length and the number of lymph nodes harvested, as objective signs of the quality of CME, related to oncological outcomes. RESULTS The CME group had a significantly longer mean operative time than the NCME group (216.3 minutes vs 191.5 minutes, P = 0.005). However, the CME group had a higher number of lymph nodes (23.8 vs 16.6; P < 0.001) and larger surgical specimens (34.3 cm vs 29.3 cm; P = 0.002). No differences were reported with respect to intraoperative blood loss, conversion rate, leakage, or other postoperative complications. CONCLUSIONS In this study laparoscopic CME were a safe and feasible technique with improvement in lymph nodes harvesting and length of surgical specimens with no increase of surgical intraoperative and postoperative complications.

Abstract
INTRODUCTION To improve oncological outcome in right colon cancer surgery, an extended mesenterectomy (D3) is under evaluation. In this procedure, all tissue anterior and posterior to the superior mesenteric vessels from the middle colic to ileocolic artery origin is removed, causing injury to the superior mesenteric nerve plexus. The aim was to study the effects of this injury on bowel dynamics and quality of life (QoL). METHODS Patients undergoing right colectomy with conventional D2- and extended D3-mesenterectomy were asked to record stool number and consistency for 60 d after surgery and complete questionnaires regarding QoL and bowel function (BF) before and after recovery from surgery. We compared early postoperative stool dynamics and long-term QoL in the groups and presented graphs depicting the temporal profile of stool numbers and consistency. RESULTS Thirty-three patients operated with a D3-resection and 12 patients with a D2-resection participated. The results revealed significantly higher stool numbers in the D3-group until day 26, with significantly more loose-watery stools until day 40. The most pronounced difference was found on day 9 (Mean difference in the total number of stools: 2.25 stools/day, p=.004. Mean difference in loose-watery stools/day: 2.81 p<.001). About 25% in the D2- and 69.7% in the D3-group reported having more than three stools/day in the early postoperative phase. There were no differences in long-term QoL and BF between the groups except in stool consistency (p=.039). DISCUSSION/CONCLUSIONS Denervation following extended D3-mesenterectomy leads to transitory reduced consistency and increased frequency. It does not affect long-term QoL or BF.

Abstract
AIM Complete mesocolic excision (CME) lacks consistent data advocating operative superiority compared to conventional surgery for colon cancer. We performed a systematic review and meta-analysis, analysing population characteristics and perioperative, pathological and oncological outcomes. METHODS D3 extended lymphadenectomy dissection was considered comparable to CME, and D2 and D1 dissection to be comparable to conventional surgery. Outcomes reviewed included lymph node yield, R1 resection, overall complications, overall survival and disease-free survival. RESULTS In all, 3039 citations were identified; 148 studies underwent full-text reviews and 31 matched inclusion criteria: total cohort 26 640 patients (13 830 CME/D3 vs. 12 810 conventional). Overall 3- and 5-year survival was higher in the CME/D3 group compared with conventional surgery: relative risk (RR) 0.69 (95% CI 0.51-0.93, P = 0.016) and RR 0.78 (95% CI 0.64-0.95, P = 0.011) respectively. Five-year disease-free survival also demonstrated CME/D3 superiority (RR 0.67, 95% CI 0.52-0.86, P < 0.001), with similar findings at 1 and 3 years. There were no statistically significant differences between the CME/D3 and conventional group in overall complications (RR 1.06, 95% CI 0.97-1.14, P = 0.483) or anastomotic leak (RR 1.02, 95% CI 0.81-1.29, P = 0.647). CONCLUSIONS Meta-analysis suggests CME/D3 may have a better overall and disease-free survival compared to conventional surgery, with no difference in perioperative complications. Quality of evidence regarding survival is low, and randomized control trials are required to strengthen the evidence base.

Abstract
Hintergrund Die A. mesenterica superior (AMS) wird im Rahmen von Pankreasresektionen (PR) und mesenterialen Gefäßeingriffen (MG) freigelegt und disseziert. Eine dadurch entstandene Schädigung des umliegenden ex- und intrinsischen vegetativen Nervenplexus kann zu einer passageren oder therapierefraktären Diarrhö führen. Fragestellung Die vorliegende Studie soll einen Überblick über den derzeitigen Stellenwert der AMS-Revaskularisations- und -Dissektions-assoziierten Diarrhö („superior mesenteric artery revascularisation and dissection-associated diarrhea“[SMARD]-Syndrom) in Deutschland geben. Material und Methoden Nach selektiver Literaturrecherche (SLR) mit der Fragestellung, ob und wie häufig eine postoperativ neu aufgetretene Diarrhö nach PR und MG vorkommt, wurde eine Onlineumfrage versendet. Ergebnisse Die SLR (n = 4) bestätigte, dass eine postoperativ neu aufgetretene Diarrhö eine häufige Komplikation nach Präparation zur Revaskularisation (RV) bzw. Dissektion (DIS) der AMS ist (Inzidenz ca. 62 %). Therapierefraktäre Verläufe sind selten 14 %. 54 von 159 Zentren beteiligten sich an der Umfrage. 63 % gaben an, eine AMS-RV/-DIS im Rahmen von PR oder MG durchzuführen. Der Durchschnitt an PR pro Zentrum lag 2018 bei 47 und bei 49 im Jahr 2019. Fünf MG erfolgten durchschnittlich in beiden Jahren pro Zentrum. Drei Patienten litten durchschnittlich am SMARD-Syndrom. Diskussion Diese Umfrage erfasst erstmals den derzeitigen Stellenwert des SMARD-Syndroms in Deutschland. Bisher fehlen Empfehlungen zur Therapie einer solchen Diarrhö. Die Ergebnisse zeigen, dass zunächst eine symptomatische Therapie erfolgen sollte. Aufgrund der Komplexität der Pathophysiologie sind kausale Therapieansätze bislang nicht entwickelt.

Abstract
BACKGROUNDS Previous systematic reviews suggest that the implementation of 'complete mesocolon excision' (CME) for colon tumors entails better specimen quality but with limited long-term outcomes. We performed a meta-analysis to compare the pathological, perioperative, and oncological results of CME with conventional surgery (CS) in primary colon cancer. METHODS Embase, MEDLINE and CENTRAL databases were searched using Medical Subject Headings for CME and D3 lymphadenectomy. The systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS A total of 18,989 patients from 27 studies were included. Postoperative complications were higher in the CME group (relative risk [RR] 1.13, 95% confidence interval [CI] 1.04-1.22, I2 = 0%), while no differences were observed in terms of anastomotic leak (I2 = 0%) or perioperative mortality (I2 = 49%). CME was associated with a higher number of lymph nodes harvested (I2 = 95%), distance to high tie (I2 = 65%), bowel length (I2 = 0%), and mesentery area (I2 = 95%). CME also had positive effects on 3- and 5-year overall survival (RR 1.09, 95% CI 1.04-1.15, I2 = 88%; and RR 1.05, 95% CI 1.02-1.08, I2 = 62%, respectively) and 3-year disease-free survival (RR 1.10, 95% CI 1.04-1.17, I2 = 22%), as well as decreased local (RR 0.35, 95% CI 0.24-0.51, I2 = 51%) and distant recurrences (RR 0.71, 95% CI 0.60-0.85, I2 = 34%). CONCLUSIONS Limited evidence suggests that CME improves oncological outcomes with a higher postoperative adverse events rate but no increase in anastomotic leak rate or perioperative mortality, compared with CS.

Abstract
BACKGROUND D3 lymph node dissection is becoming the standard procedure for the treatment of advanced right colon cancer and has shown increasing evidence of its oncologic benefit. However, a clear indication for its application is lacking and data on this topic is unsatisfactory. Thus, the necessity for D3 lymph node dissection in clinical stage I right colon cancer remains controversial. METHODS We retrospectively analyzed data from clinical stage I right colon cancer patients who underwent radical surgery at three hospitals of Korea university medical center between January 2015 and June 2018. We compared surgical complications and short-term oncologic outcomes between D2 and D3 lymph node dissections in these patients. RESULTS Among 512 patients, 122 (23.8%) were clinical stage I. Of these, 88 and 34 patients received D2 and D3 lymph node dissection, respectively. There were no statistically significant differences in clinicopathologic variables and surgical outcomes between the two groups. Upstaging occurred in 16 patients (47.1%) in the D3 group and 23 patients (26.1%) in the D2 group. There were four recurrences in the D2 group but no recurrence in the D3 group. Log-rank tests showed no statistically significant difference in disease-free survival rates between the two groups (p = 0.210). CONCLUSION There was no significant difference in disease-free survival rates between D2 and D3 lymph node dissection in clinical stage I right colon cancer patients. However, recurrence occurred in the D2 group. Efforts to improve the accuracy of clinical staging are required and more studies with better quality are needed.

Abstract
BACKGROUND While complete mesocolic excision (CME) has been shown to have an oncological benefit as compared to conventional colonic surgery for colon surgery, this benefit must be weighed up against the risk of major intra-abdominal complications. This paper aimed to assess the comparative oncological benefits of CME. METHODS Following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, a systematic review of the literature until May 2020 was performed. Comparative studies assessing CME versus conventional colonic surgery for colon cancer were compared, and outcomes were pooled. RESULTS A total of 700 publications were identified, of which 19 were found to meet the inclusion criteria. A total of 25 886 patients were compared, with 14 431 patients in the CME arm. CME was associated with a significantly higher rate of vascular injury (odds ratio 3, P < 0.001). Rates of local and distant recurrence were lower in the CME group (odds ratio 0.66 and 0.73, respectively, both P < 0.001). CME patients had a significantly higher lymph node yield (P < 0.001). While no significant differences were noted between the two groups in terms of pooled 3- or 5-year disease-free survival, pooled 5-year overall survival was significantly higher in the CME group (relative risk 0.82, P < 0.001). CONCLUSION Based on the available evidence, CME is associated with improved oncologic outcomes at the expense of higher complication rates, including vascular injury. The oncological benefits need to weighed up against a multitude of factors including the level of hospital support, surgeon experience, patient age, and associated comorbidities.

Abstract
INTRODUCTION As survival rates of colon cancer increase, knowledge about functional outcomes is becoming ever more important. The primary aim of this systematic review and meta-analysis was to quantify functional outcomes after surgery for colon cancer. Secondly, we aimed to determine the effect of time to follow-up and type of colectomy on postoperative functional outcomes. MATERIALS AND METHODS A systematic literature search was performed to identify studies reporting bowel function following surgery for colon cancer. Outcome parameters were bowel function scores and/or prevalence of bowel symptoms. Additionally, the effect of time to follow-up and type of resection was analyzed. RESULTS In total 26 studies were included, describing bowel function between 3 to 178 months following right hemicolectomy (n = 4207), left hemicolectomy/sigmoid colon resection (n = 4211), and subtotal/total colectomy (n = 161). In 16 studies (61.5%) a bowel function score was used. Pooled prevalence for liquid and solid stool incontinence was 24.1% and 6.9%, respectively. The most prevalent constipation-associated symptoms were incomplete evacuation and obstructive, difficult emptying (33.3% and 31.4%, respectively). Major Low Anterior Resection Syndrome was present in 21.1%. No differences between time to follow-up or type of colectomy were found. CONCLUSION Bowel function problems following surgery for colon cancer are common, show no improvement over time and do not depend on the type of colectomy. Apart from fecal incontinence, constipation-associated symptoms are also highly prevalent. Therefore, more attention should be paid to all possible aspects of bowel dysfunction following surgery for colon cancer and targeted treatment should commence promptly.

Abstract
BACKGROUND Changes in bowel function after right-sided colectomy are not well understood compared to those associated with left-sided colectomy or rectal resection. In particular, there are concerns about bowel function after right-sided colectomy with complete mesocolic excision, which has become popular in the West.
AIM To evaluate the functional outcomes of patients who underwent right-sided colectomy with D3 lymphadenectomy for colon cancer.
METHODS Functional data from patients who underwent minimally invasive right-sided colectomy for colon cancer from October 2017 to September 2018 were prospectively collected. Functional outcomes were evaluated preoperatively and at 3, 6, 12, and 18 mo postoperatively.
RESULTS Prior to surgery, 57 patients answered the questionnaire, and 47 responded at three months, 52 at 6 mo, 52 at 12 mo, and 25 at 18 mo postoperatively. Most scales of quality of life and bowel function improved significantly over time. Urgency persisted to a high degree throughout the period without a significant change over time. The use of medications for defecation was about 10% over the entire period. Gas (P = 0.023) and fecal frequency (P < 0.001) increased, and bowel dysfunction group (P = 0.028) was more common among patients taking medication. At six months, resected bowel and colon lengths were significantly different as a risk factor between the dysfunction group and the no dysfunction group [odd ratio (OR): 1.095, P = 0.026; OR: 1.147, P = 0.031, respectively] in univariate analysis, but not in multivariate analysis.
CONCLUSION Despite D3 lymphadenectomy, most bowel symptoms improved over time after right-sided colectomy using a minimally invasive approach, and continuous medication was needed in only approximately 10% of patients.

Abstract
BACKGROUND Right-sided cancer accounts for approximately 30% of bowel cancer in women and 22% in men. Colonic resection can cause changes in bowel function which affect daily activity. The aims are to assess the impact of right hemicolectomy for cancer on bowel function and to identify useful treatment modalities for managing bowel dysfunction after right hemicolectomy. METHOD The review was conducted in line with PRISMA. Eligible studies evaluated the impact of right hemicolectomy on bowel function in those treated for colorectal neoplasia or assessed the effect of surgical technique or other intervention on bowel function after right hemicolectomy. Right hemicolectomy for inflammatory bowel disease or benign cases only were excluded. Articles were limited to studies on human subjects written in English published between January 2008 and December 2018. RESULTS The searches identified 7531 articles. Nine articles met the inclusion criteria, of which eight were cohort studies and one was a randomised trial. Loose stool, increased bowel frequency and/or nocturnal defaecation following right-sided colectomy occurs in approximately one in five patients. Some of these symptoms may improve spontaneously with time. Bile acid malabsorption and/or small bowel bacterial overgrowth may be the cause for chronic dysfunction. Some studies report that no or little difference in outcome between right-sided and rectal resections likely suggests poor function after right-sided resection. CONCLUSION Right hemicolectomy can result in changes to bowel function. Patients should be counselled preoperatively, and follow-up should be designed to identify and effectively treat significantly altered bowel function.

Abstract
BACKGROUND Complete mesocolic excision (CME) is advocated based on oncologic superiority, but not commonly performed in North America. Many data are case series with few comparative studies. Our aim was to perform a systematic review comparing outcomes between CME and non-CME colectomy. METHODS A systematic review was performed according to PRISMA guidelines of MEDLINE, EMBASE, HealthStar, Web of Science, and Cochrane Library. Studies were included if they compared conventional resection (non-CME) to CME for colon cancer. Quality was assessed using methodological index for non-randomized studies (MINORS). The main outcome measures were short-term morbidity and oncologic outcomes. Weighted pooled means and proportions with 95% CI were calculated using a random-effects model when appropriate. RESULTS Out of 825 unique citations, 23 studies underwent full-text reviews and 14 met inclusion criteria. Mean MINORS score was 13.3 (range 11-15). The mean sample size in CME group was 1166 (range 45-3756) and 945 (range 40-3425) in non-CME. Four papers reported plane of dissection, with CME plane achieved in 85.8% (95% CI 79.8-91.7). Mean OR time in CME group was 167 min (163-171) and 138 min (135-142) in conventional group. Perioperative morbidity was reported in six studies, with pooled overall complications of 22.5% (95% CI 18.4-26.6) for CME and 19.6 (95% CI 13.6-25.5) for non-CME. Anastomotic leak occurred in 6.0% (95% CI 2.2-9.7) of CME resections versus 6.0% (95% CI 4.1-7.9) in non-CME. CME had more lymph nodes, longer distance to high tie, and specimen length in all studies. Nine studies compared long-term oncologic outcomes and only three reported statistically significant higher disease-free or overall survival in favor of CME. Local recurrence was lower after CME in two of four studies. CONCLUSIONS The quality of evidence is limited and does not consistently support the superiority of CME. Better data are needed before CME can be recommended as the standard of care for colon cancer resections.

Abstract
BACKGROUND Right hemicolectomy is a very common surgery. Many studies compare different options for laparoscopic ileocolic anastomoses: intra- or extracorporeal; handsewn or stapled; side-to-side or end-to-side. However, there are no studies about the influence that peristalsis could have on this anastomosis. The aim of this study is to compare safety and feasibility of isoperistaltic and antiperistaltic anastomosis in terms of postoperative morbidity and mortality between both groups. The secondary endpoint is to compare long-term functional outcomes (chronic diarrhoea) and quality of life (GIQLI questionnaire) after a 1-year follow-up period. METHODS A double-blind, randomised, prospective trial in patients undergoing scheduled surgery for right colon cancer with laparoscopic right hemicolectomy and isoperistaltic (ISO) or antiperistaltic (ANTI) ileocolic anastomoses. RESULTS Hundred and eight patients were included in the study. Patients were randomised either to isoperistaltic or antiperistaltic configuration (54 ISO/ANTI). No significant differences in baseline variables were found. No differences in surgical time (130 [120-150] min ISO vs. 140 [127-160] ANTI, p = 0.481), nor in anastomotic time (19 [17-22] vs. 20 [16-25], p = 0.207) and nor in postoperative complications: 37.0% ISO versus 40.7% ANTI, (p = 0.693) were found. There were no differences in postoperative ileus (p = 0.112) nor in anastomotic leakage (3.7% vs. 5.56%, p = 1.00). Differences in "time to first flatus" and "time to first deposition" were found in favour of the antiperistaltic group (p = 0.004 and p = 0.017). Anastomotic configuration did not influence hospital stay (3 days [2-6] isoperistaltic vs. 3 [2-4] antiperistaltic, p = 0.236). During follow-up, there were no differences between the two groups at 1, 6 and 12 months (p = 0.154, p = 0.498 and p = 0.683), nor in chronic diarrhoea rates in GIQLI scores (24% ISO vs. 31.4% ANTI, p = 0.541). CONCLUSIONS The isoperistaltic and antiperistaltic ileocolic anastomosis present similar results in terms of performance, safety and functionality. However, further studies must be carried out in order to assess relationship between postoperative ileus and anastomosis configuration. TRIAL REGISTRATION Randomised Clinical trial (Identifier: NCT02309931).

Abstract
BACKGROUND Complete mesocolic excision improves the long-term outcome of colon cancer but might carry a risk of bowel dysfunction. OBJECTIVE This study aimed to investigate whether right-sided complete mesocolic excision is associated with an increased risk of long-term bowel dysfunction and reduced quality of life compared with conventional colon cancer resections. DESIGN Data were extracted from a population-based study comparing complete mesocolic excision and conventional colon cancer resections and from a national questionnaire survey regarding functional outcome. SETTINGS Elective right-sided colon resections for stage I to III colon adenocarcinoma were performed at 4 university colorectal centers between June 2008 and December 2014. PATIENTS Seven hundred sixty-two patients were eligible to receive the questionnaire in November 2015. MAIN OUTCOME MEASURES The primary outcomes measured were the risk of diarrhea (Bristol stool scale score of 6-7), 4 or more bowel movements daily, and the impact of bowel function on quality of life. Secondary outcomes were other bowel symptoms, chronic pain, and quality of life measured by the European Organisation for Research and Treatment of Cancer QLQ-C30. RESULTS One hundred forty-one (63.8%) and 324 (59.9%) patients undergoing complete mesocolic excision and conventional resections responded after a median of 3.99 (interquartile range, 2.11-5.32) and 4.11 (interquartile range, 3.01-5.53) years (p = 0.04). Complete mesocolic excision was not associated with increased risk of diarrhea (adjusted OR, 1.07; 95% CI, 0.57-1.95; p = 0.84), 4 or more bowel movements daily (adjusted OR, 1.16; 95% CI, 0.57-2.24; p = 0.68), or lower quality of life (adjusted OR, 0.84; 95% CI, 0.49-1.40; p = 0.50). Complete mesocolic excision was associated nonsignificantly with nocturnal bowel movements, but not associated with chronic pain or other secondary outcomes. LIMITATIONS This study was limited by the retrospective design with unknown baseline symptoms. Responding patients were younger but without obvious selection bias. The outcome "diarrhea" seemed somehow sensitive to information bias. CONCLUSION Right-sided complete mesocolic excision seems associated with neither bowel dysfunction nor impaired quality of life when compared with conventional surgery.

A Pre- and Post-operative, Prospective, Within Subject Trial. J Neurogastroenterol Motil 2017; 23:585-591. [PMID: 28571122 PMCID: PMC5628992 DOI: 10.5056/jnm16190] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2016] [Revised: 01/31/2017] [Accepted: 03/12/2017] [Indexed: 01/14/2023] Open
Abstract
Background/Aims Wireless motility capsule (WMC) detects the ileocolic junction (ICJ) in most non-operated patients. We find no data concerning this examination in patients where the ileocolic valve is replaced by a per definition incompetent, surgically created ICJ. We wanted to see if WMC could detect the ICJ after a right colectomy and assess the competency. Methods Prospective cohort study using a within-subject design to eliminate subject-subject variability. Selected patients operated with right colectomy underwent 3 WMC examinations (pre-operatively, 3 weeks, and 6 months after surgery). Results Twenty patients (8 men) included, 7 (4 men) excluded due to poor recordings (4) and unforeseen events (3). Thirteen patients (4 men), median age 63 years completed 3 tests. Median bowel lengths removed were 11 cm for ileum and 21 cm for colon. Thirty-nine examinations analyzed by 2 physicians who found all 13 ICJs at 3 examinations with high inter-rater reliability (intra-class correlation coefficient: 0.99, 0.91, and 0.99 respectively), whereas the computer found 9, 8, and 10 out of the 13 ICJs, respectively. Computed values significantly more often deviated from the 2 raters. Mean magnitude and duration of pH-drop at the ICJ (3 examinations) was 1.16-1.02-1.13 pH units and 3.15-4.78-3.75 minutes, respectively. pH-drop was smaller and duration longer at 3 weeks. We found no differences between the pre-operative (competent ICJ) and post-operative 6-month examinations (incompetent ICJ). Highest pressure immediately prior to ICJ was equal before and after surgery. Conclusion WMC can identify the non-physiological ICJ after right colectomy. Ileocolic competence cannot be assessed.
