Laparoscopic right hemicolectomy: a SICE (Società Italiana di Chirurgia Endoscopica e Nuove tecnologie) network prospective study on the approach to right colon lymphadenectomy in Italy: is there a standard?-CoDIG 2 (ColonDx Italian Group). Surg Endosc 2024; 38:1432-1441.

Abstract
BACKGROUND Colon cancer is a disease with a worldwide spread. Surgery is the best option for the treatment of advanced colon cancer, but some aspects are still debated, such as the extent of lymphadenectomy. In Japanese guidelines, the gold standard was D3 dissection to remove the central lymph nodes (203, 213, and 223), but in 2009, Hoenberger et al. introduced the concept of complete mesocolic excision, in which surgical dissection follows the embryological planes to remove the mesentery entirely to prevent leakage of cancer cells and collect more lymph nodes. Our study describes how lymphadenectomy is currently performed in major Italian centers with an unclear indication on the type of lymphadenectomy that should be performed during right hemicolectomy (RH). METHODS CoDIG 2 is an observational multicenter national study that involves 76 Italian general surgery wards highly specialized in colorectal surgery. Each center was asked not to modify their usual surgical and clinical practices. The aim of the study was to assess the preference of Italian surgeons on the type of lymphadenectomy to perform during RH and the rise of any new trends or modifications in habits compared to the findings of the CoDIG 1 study conducted 4 years ago. RESULTS A total of 788 patients were enrolled. The most commonly used surgical technique was laparoscopic (82.1%) with intracorporeal (73.4%), side-to-side (98.7%), or isoperistaltic (96.0%) anastomosis. The lymph nodes at the origin of the vessels were harvested in an inferior number of cases (203, 213, and 223: 42.4%, 31.1%, and 20.3%, respectively). A comparison between CoDIG 1 and CoDIG 2 showed a stable trend in surgical techniques and complications, with an increase in the robotic approach (7.7% vs. 12.3%). CONCLUSIONS This analysis shows how lymphadenectomy is performed in Italy to achieve oncological outcomes in RH, although the technique to achieve a higher lymph node count has not yet been standardized.

Optimising surgical anastomosis in ileocolic resection for Crohn's disease with respect to recurrence and functionality: two international parallel randomized controlled trials comparing handsewn (END-to-end or Kono-S) to stapled anastomosis (HAND2END and the End2End STUDIES). BMC Surg 2024; 24:71. [PMID: 38408943 PMCID: PMC10895856 DOI: 10.1186/s12893-024-02340-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Accepted: 02/01/2024] [Indexed: 02/28/2024] Open
Abstract
BACKGROUND The most common intestinal operation in Crohn's disease (CD) is an ileocolic resection. Despite optimal surgical and medical management, recurrent disease after surgery is common. Different types of anastomoses with respect to configuration and construction can be made after resection for example, handsewn (end-to-end and Kono-S) and stapled (side-to-side). The various types of anastomoses might affect endoscopic recurrence and its assessment, the functional outcome, and costs. The objective of the present study is to compare the three types of anastomoses with respect to endoscopic recurrence at 6 months, gastrointestinal function, and health care consumption. METHODS This is a randomized controlled multicentre superiority trial, allocating patients either to side-to-side stapled anastomosis as advised in current guidelines or a handsewn anastomoses (an end-to-end or Kono-S). It is hypothesized that handsewn anastomoses do better than stapled, and end-to-end perform better than the saccular Kono-S. Two international studies with a similar setup will be conducted mainly in the Netherlands (End2End) and Italy (HAND2END). Patients diagnosed with CD, aged over 16 years in the Netherlands and 18 years in Italy requiring (re)resection of the (neo)terminal ileum are eligible. The first part of the study compares the two handsewn anastomoses with the stapled anastomosis. To detect a clinically relevant difference of 25% in endoscopic recurrence, a total of 165 patients will be needed in the Netherlands and 189 patients in Italy. Primary outcome is postoperative endoscopic recurrence (defined as Rutgeerts score ≥ i2b) at 6 months. Secondary outcomes are postoperative morbidity, gastrointestinal function, quality of life (QoL) and costs. DISCUSSION The research question addresses a knowledge gap within the general practice elucidating which type of anastomosis is superior in terms of endoscopic and clinical recurrence, functionality, QoL and health care consumption. The results of the proposed study might change current practice in contrast to what is advised by the guidelines. TRIAL REGISTRATION NCT05246917 for HAND2END and NCT05578235 for End2End ( http://www.

Isoperistaltic vs antiperistaltic anastomosis after right hemicolectomy: A comprehensive review. World J Clin Cases 2023; 11:1694-1701. [PMID: 36970003 PMCID: PMC10037296 DOI: 10.12998/wjcc.v11.i8.1694] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2022] [Revised: 01/28/2023] [Accepted: 02/21/2023] [Indexed: 03/07/2023] Open
Abstract
To optimize the efficiency of ileocolic anastomosis following right hemicolectomy, several variations of the surgical technique have been tested. These include performing the anastomosis intra- or extracorporeally or performing a stapled or hand-sewn anastomosis. Among the least studied is the configuration of the two stumps (i.e., isoperistaltic or antiperistaltic) in the case of a side-to-side anastomosis. The purpose of the present study is to compare the isoperistaltic and antiperistaltic side-to-side anastomotic configuration after right hemicolectomy by reviewing the relevant literature. High-quality literature is scarce, with only three studies directly comparing the two alternatives, and no study has revealed any significant differences in the incidence of anastomosis-related complications such as leakage, stenosis, or bleeding. However, there may be a trend towards an earlier recovery of intestinal function following antiperistaltic anastomosis. Finally, existing data do not identify a certain anastomotic configuration (i.e., isoperistaltic or antiperistaltic) as superior over the other. Thus, the most appropriate approach is to master both anastomotic techniques and select between the two configurations based on each individual case scenario.

Abstract
PURPOSE Anastomotic leak (AL) following ileocolic anastomosis is a cause of significant morbidity and mortality. Stapled end-to-side (ESA), stapled side-to-side (SSA), and handsewn anastomoses (HSA) are commonly performed techniques. There is however conflicting data on the superiority of one technique over the other. The aim of this study was to compare the outcomes of ESA against SSA and HSA. METHODS This retrospective cohort study was conducted at a tertiary colorectal unit. All patients who underwent an ileocolic anastomosis from October 2008 to May 2020 were included. Exclusion criteria were missing data on anastomotic technique or clinicopathological variables. Primary outcomes were AL and anastomotic bleeding (AB). Secondary outcomes were length of stay (LoS) and return of gut function. RESULTS A total of 1390 patients met the inclusion criteria. A total of 976 (70%) ESA, 308 (22%) SSA, and 108 (8%) HSA were performed. AL occurred in 17/1390 (1.2%) patients, and 54/1390 (3.9%) had AB. On adjusted analysis, ESA experienced a lower AL when compared with SSA (OR 4.93, p = 0.005), with a trend towards a lower AL when compared to HSA (OR 2.6, p = 0.27). There was no difference in AB between all techniques: ESA vs. SSA (OR 1.07 p = 0.84), and ESA vs. HSA (OR 0.24 p = 0.76). Both stapled techniques were associated with a shorter return to gut function compared to HSA; 3.3 vs. 4.2 days (p < 0.001). There was no difference in LoS. CONCLUSION ESA has the lowest leak rate when compared to other anastomotic techniques without any increased risk of anastomotic bleeding.

Iatrogenic caecal perforation two days after a caesarean section, a case report. Ann Med Surg (Lond) 2021; 71:102924. [PMID: 34703587 PMCID: PMC8521232 DOI: 10.1016/j.amsu.2021.102924] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Accepted: 10/03/2021] [Indexed: 02/07/2023] Open
Abstract
INTRODUCTION and importance: The caesarean section is a widely spread procedure and 29.7 million times performed every year inn 169 countries in the world. Overall, complications are seen in 6% for elective caesarean to 15% for emergency caesarean. CASE PRESENTATION We here report a case which was initially diagnosed as a postoperative paralytic ileus. After a complicated caesarean section caused by bleeding and problems with haemostasis, a healthy child was born with full mother recovery for the first 24 hours after surgery. Unfortunately, her condition deteriorated between 24 and 48 hours and she reported progressive nausea and painful bloating. Laboratory tests and CT imaging showed progressive signs of inflammation and distention of the caecum and colon. A second CT scan the next day revealed signs of perforation. An ileocecal resection was performed with a primary anastomosis. Full recovery occurred two weeks later. CLINICAL DISCUSSION With an estimated incidence of only 0,08%, bowel perforations due to caesarean section, are rare. Moreover, is the clinical presentation diverse and computed topography is essential during the diagnostic process. To avoid potential morbidity and mortality, the surgeon must consider performing a laparotomy in case of a deteriorating patient in non-invasive treatment fails. CONCLUSION Caecal perforation must be considered as complication after a caesarean section. An ileocecal resection is necessary in this situation. This case report shows that a primary anastomosis is a possible option in a healthy patient that is hemodynamically stable during the operation. In case of an unhealthy or hemodynamic unstable patient, the safest option is a temporary ileostomy.

C-reactive protein level on postoperative day 3 as a predictor of anastomotic leakage after elective right-sided colectomy. Surg Today 2021; 52:337-343. [PMID: 34370104 DOI: 10.1007/s00595-021-02351-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Accepted: 05/24/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE To investigate the factors predictive of anastomotic leakage in patients undergoing elective right-sided colectomy. METHODS The subjects of this retrospective study were 247 patients who underwent elective right hemicolectomy or ileocecal resection with ileocolic anastomosis between April 2012 and March 2019, at our institution. RESULTS Anastomotic leakage occurred in 9 of the 247 patients (3.6%) and was diagnosed on median postoperative day (POD) 7 (range POD 3-12). There were no significant differences in the background factors or preoperative laboratory data between the patients with anastomotic leakage (anastomotic leakage group) and those without anastomotic leakage (no anastomotic leakage group). Open surgery was significantly more common than laparoscopic surgery (P = 0.027), and end-to-side anastomosis was less common (P = 0.025) in the anastomotic leakage group. The C-reactive protein (CRP) level in the anastomotic leakage group was higher than that in the no anastomotic leakage group on PODs 3 (P < 0.001) and 5 (P < 0.001). ROC curve analysis revealed that anastomotic leakage was significantly more frequent in patients with a serum CRP level ≥ 11.8 mg/dL [area under the curve (AUC) 0.83]. CONCLUSION A serum CRP level ≥ 11.8 mg/dL on POD 3 was predictive of anastomotic leakage being detected on median POD 7.

Objective recovery time with end-to-side versus side-to-side anastomosis after laparoscopic right hemicolectomy for colon cancer: a randomized controlled trial. Surg Endosc 2021; 36:2499-2506. [PMID: 34008107 DOI: 10.1007/s00464-021-08536-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2021] [Accepted: 04/30/2021] [Indexed: 10/21/2022]
Abstract
BACKGROUND Despite reports of the short-term benefits of end-to-side versus side-to-side anastomosis, we are aware of no prospective studies in which these methods were compared. We hypothesized the superiority of end-to-side over side-to-side anastomosis in terms of recovery after laparoscopic right hemicolectomy for colon cancer under an enhanced recovery program. METHODS From September 2016 to August 2019, 130 patients were randomly allocated to receive end-to-side or side-to-side anastomosis at a single tertiary hospital in Korea. The primary outcome was the cumulative recovery rate seven days after surgery, defined as the percentage of patients who met all four recovery criteria: diet tolerance, no analgesia, safe ambulation, and an afebrile status. Student's t test, the Mann-Whitney U test, the χ2 test, and Fisher's exact test were used to compare variables, as applicable. RESULTS The cumulative recovery rate at seven days did not differ between patients receiving end-to-side (92.3%, 60/65) or side-to-side anastomosis (92.3%, 60/65; P ≥ 0.999). The end-to-side and side-to-side groups had similar cumulative recovery rates at postoperative days 4, 5, and 6 (end-to-side vs. side-to-side: 41.5% vs 35.4%, P = 0.589; 73.8% vs 63.1%, P = 0.257; and 86.2% vs 81.5%, P = 0.634, respectively). None of the secondary endpoints differed for end-to-side vs. side-to-side anastomosis: the median length of postoperative hospitalization (5 [IQR 5-7] vs. 6 [IQR 5-7] days, respectively, P = 0.376), the 30-day complication rate (16.9% vs. 12.3%, respectively, P = 0.620), the enhanced recovery protocol failure rate (10.8% vs. 7.7%, respectively, P = 0.763), and the 30-day readmission rate (4.6% vs. 3.1%, respectively, P ≥ 0.999). CONCLUSIONS End-to-side anastomosis was not superior to side-to-side anastomosis in terms of recovery criteria after laparoscopic right hemicolectomy. These findings do not provide evidence for a functional advantage of end-to-side compared to side-to-side anastomosis.

Abstract
Intracorporeal anastomosis (IA) may improve outcomes compared with extracorporeal anastomosis (EA) in minimally invasive right colectomy. This is a prospective series of robotic right hemicolectomies (RRC) with IA from one institution. 35 consecutive patients with verified or suspected right colon cancer undergoing RRC with IA, and historic control groups of 22 RRC and 40 laparoscopic right colectomies (LRC), both with EA. Primary outcome measure was length of stay (LOS). Secondary outcome measures were 30-day complication rates, readmissions, pain scores, analgesic consumption, and specimen quality. Median LOS did not differ significantly between the groups (RRC-IA, 4 days; LRC-EA, 4 days; RRC-EA, 5 days). In-hospital surgical complications Clavien–Dindo 3 + were seen in 1, 2, and 0 patients, respectively, and 3, 5, and 3 patients were readmitted to hospital within 30 days. Median pain score was 2 in all groups on postoperative day (POD) 2. Relatively more patients in the RRC-IA group received gabapentin on POD 2 (p = 0.006), but use of other analgetics did not differ between groups. Mean specimen lengths were 31, 25 and 27 cm, respectively (RRC-IA vs. LRC-EA, p = 0.003), but mesentery width, proportion of mesocolic excisions and number of lymph nodes did not differ between the groups. RRC-IA was not associated with shorter LOS, fewer complications or better specimen quality than recent controls undergoing either RRC-EA or LRC-EA.

Abstract
INTRODUCTION Delayed gastrointestinal (GI) recovery remains a significant morbidity after colorectal surgery. Intracorporeal anastomosis for right colectomy may hasten GI recovery. Therefore, the objective of this study was to determine the effect of intracorporeal versus extracorporeal anastomosis on GI recovery after elective laparoscopic right colectomy within an established ERAS program. METHODS Adult patients undergoing elective laparoscopic right colectomy at a single high-volume institution from 07/2014 to 12/2018 were reviewed. Patients were divided into two groups: intracorporeal (IC) and extracorporeal (EC). The primary outcome was time to GI-3 defined as days to tolerance of solid diet and first flatus/bowel movement. Prolonged postoperative ileus (PPOI) was defined as GI-3 not met by postoperative day 4. Secondary outcomes were length of stay (LOS) and overall 30-day complications. Sensitivity analysis was performed using coarsened exact matching to account for unmeasured confounding. Multiple regression was performed using a Cox proportional hazard model to identify predictors of GI recovery. RESULTS A total of 346 patients were reviewed, of which 226 were included (71IC, 155EC). Patient characteristics were well balanced between groups: mean age was 64.9 years (SD 15.9), BMI was 26.3 (SD 5.7), 38.1% of patients had ASA ≥ 3, and 78.3% underwent surgery for neoplasms. IC anastomosis was associated with longer operative duration (165 min (SD 40); 144 min (SD 48), p = 0.002). There was no difference in the median time to GI-3 (IC 2 days [IQR1-2]; EC 2 days [IQR2-3], p = 0.135). The incidence of PPOI (IC 8.5%; EC 10.3%, p = 0.659), superficial SSI (4.2% vs. 5.8%, p = 0.757), deep SSI (2.8% vs. 5.2%, p = 0.729), and median LOS (3 days [IQR 2-4] vs. 3 [IQR 3-5], p = 0.059) were also similar. On multivariate analysis, IC anastomosis did not independently predict faster GI recovery (HR 0.98, 95% CI 0.71-1.34). Similar results were observed in the matched cohort (185 patients (61IC, 124EC)). CONCLUSION In this study, IC anastomosis was not associated with faster GI recovery or reduced complication rate compared to EC anastomosis. Longer term studies may be required to determine the potential benefits of IC anastomosis.

Abstract
BACKGROUND Anastomotic leak (AL) after ileocolic anastomosis influences morbidity, mortality, length of hospitalization and costs. This study analyzes risk and protective factors for AL on ileocolic anastomoses. METHODS We retrospectively analyzed our single institution patients' series undergoing elective ileocolic anastomosis for AL between 1/2008-12/2017. AL grade A/B (antibiotic treatment and/or radiological drainage) were summarized as mild, grade C (surgical re-intervention) corresponds to severe AL. RESULTS We included 470 patients (mean age 70.8 years, 43.2% females). Overall AL rate was 9.4% (44 patients) with 6.0% severe and 3.4% mild AL. There was no difference in AL between hand sewn and stapled anastomoses. Multivariate analysis revealed preoperative serum albumin (p = 0.004), smoking habits (p = 0.005) and perioperative blood transfusion (p = 0.038) as risk factors for AL. Suture oversewing as anastomotic reinforcement resulted as independent protective factor (p < 0.001). CONCLUSION Poor nutritional status, smoking habits and perioperative blood transfusion are negative factors influencing on AL. Suture oversewing as anastomotic reinforcement associates with significantly less AL.

Abstract
INTRODUCTION There are no definitive data concerning the ideal configuration of ileocolic anastomosis. Aim of this study was to identify perioperative risk factors for anastomotic leak and for 60-day morbidity and mortality after ileocolic anastomoses (stapled vs handsewn). MATERIALS AND METHODS This is a STROBE-compliant study. Demographic and surgical data were gathered from patients with an ileocolic anastomosis performed between November 2010 and September 2016 at a tertiary hospital. Anastomoses were performed using standardised techniques. Independent risk factors for anastomotic leak, complications and mortality were assessed. RESULTS We included 477 patients: 53.7% of the anastomoses were hand sewn and 46.3% stapled. Laterolateral anastomosis was the most common configuration (93.3%). Anastomotic leak was diagnosed in 8.8% of patients and 36 were classified as major anastomotic leak (7.5%). In the multivariate analysis, male sex (P = 0.014, odds ratio, OR, 2.9), arterial hypertension (P = 0.048, OR 2.29) and perioperative transfusions (P < 0.001, OR 2.4 per litre) were independent risk factors for major anastomotic leak. The overall 60-day complication rate was 27.3%. Male sex (31.3% vs female 22.3%, P = 0.02, OR 1.7), diabetes (P = 0.03 OR 2.0), smoking habit (P = 0.04, OR 1.8) and perioperative transfusions (P < 0.001, OR 3.3 per litre) were independent risk factors for postoperative morbidity. The 60-day-mortality rate was 3.1% and no significant risk factors were identified. CONCLUSION Anastomotic leak after ileocolic anastomosis is a relevant problem. Male sex, arterial hypertension and perioperative transfusions were associated with major anastomotic leak. Conversion to open surgery was more frequently associated with perioperative death.

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
AIM Foreshortened mesentery or thick abdominal wall constitutes a rationale for laparoscopic intracorporeal ileocolic anastomoses (ICA). The aim of this study was to compare intracorporeal to extracorporeal ICA in terms of surgical site infections in patients with Crohn's ileitis and overweight patients with right colon tumors. METHOD This was a prospective propensity score-matched cohort study enrolling consecutive patients with Crohn's terminal ileitis and overweight patients with right colon tumors undergoing elective laparoscopic right colon resection with intracorporeal or extracorporeal ICA. Propensity score matching with a 1:1 ratio was employed to compare diagnosis-matched patients for age, BMI, ASA, and previous abdominal surgery. RESULTS Overall, 453 patients were enrolled: 233 intracorporeal vs. 220 extracorporeal. Propensity score matching left 195 intracorporeal and 195 extracorporeal patients comparable for age (p = 0.294), gender (p = 0.683), ASA (p = 0.545), BMI (p = 0.079), previous abdominal surgery (p = 0.348), and diagnosis (p = 0.301). Conversion rates (5.1 vs. 3.6%; p = 0.457) and intraoperative complications (1 vs. 2.1%; p = 0.45) were similar. Overall morbidity (5.1 vs. 12.8%; p = 0.008) and re-intervention rates (3.1 vs. 8.7%; p = 0.029) were significantly higher in extracorporeal patients. Anastomotic leak rates (0.5 vs. 1.5%; p = 0.623) did not differ. Incisional SSI rate was significantly higher in extracorporeal patients (p = 0.01). CONCLUSION Laparoscopic intracorporeal ICA reduced incisional SSI rates as compared to its extracorporeal counterpart.

Robotic right hemicolectomy: Analysis of 108 consecutive procedures and multidimensional assessment of the learning curve. Surg Oncol 2016; 26:28-36. [PMID: 28317582 DOI: 10.1016/j.suronc.2016.12.005] [Citation(s) in RCA: 50] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2016] [Accepted: 12/18/2016] [Indexed: 01/16/2023]
Abstract
PURPOSE Surgeons tend to view the robotic right colectomy (RRC) as an ideal beginning procedure to gain proficiency in robotic general and colorectal surgery. Nevertheless, oncological RRC, especially if performed with intracorporeal ileocolic anastomosis confectioning, cannot be considered a technically easier procedure. The aim of this study was to assess the learning curve of the RRC performed for oncological purposes and to evaluate its safety and efficacy investigating the perioperative and pathology outcomes in the different learning phases. METHODS Data on a consecutive series of 108 patients undergoing RRC with intracorporeal anastomosis between June 2011 and September 2015 at our institution were prospectively collected to evaluate surgical and short-term oncological outcomes. CUSUM (Cumulative Sum) and Risk-Adjusted (RA) CUSUM analysis were performed in order to perform a multidimensional assessment of the learning curve for the RRC surgical procedure. Intraoperative, postoperative and pathological outcomes were compared among the learning curve phases. RESULTS Based on the CUSUM and RA-CUSUM analyses, the learning curve for RRC could be divided into 3 different phases: phase 1, the initial learning period (1st-44th case); phase 2, the consolidation period (45th-90th case); and phase 3, the mastery period (91th-108th case). Operation time, conversion to open surgery rate and the number of harvested lymph nodes significantly improve through the three learning phases. CONCLUSIONS The learning curve for oncological RRC with intracorporeal anastomosis is composed of 3 phases. Our data indicate that the performance of RRC is safe from an oncological point of view in all of the three phases of the learning curve. However, the technical skills necessary to significantly reduce operative time, conversion to open surgery rate and to significantly improve the number of harvested lymph nodes were achieved after 44 procedures. These data suggest that it might be prudent to start the RRC learning curve by treating only benign diseases and to reserve the performance of oncological resection to when at least the initial learning phase has been completed.

Risk factors for anastomotic leak and postoperative morbidity and mortality after elective right colectomy for cancer: results from a prospective, multicentric study of 1102 patients. Int J Colorectal Dis 2016; 31:105-14. [PMID: 26315015 DOI: 10.1007/s00384-015-2376-6] [Citation(s) in RCA: 107] [Impact Index Per Article: 13.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 08/16/2015] [Indexed: 02/06/2023]
Abstract
BACKGROUND Studies focused on postoperative outcome after oncologic right colectomy are lacking. The main objective was to determine pre-/intraoperative risk factors for anastomotic leak after elective right colon resection for cancer. Secondary objectives were to determine risk factors for postoperative morbidity and mortality. METHODS Fifty-two hospitals participated in this prospective, observational study (September 2011-September 2012), including 1102 patients that underwent elective right colectomy. Forty-two pre-/intraoperative variables, related to patient, tumor, surgical procedure, and hospital, were analyzed as potential independent risk factors for anastomotic leak and postoperative morbidity and mortality. RESULTS Anastomotic leak was diagnosed in 93 patients (8.4 %), and 72 (6.5 %) of them needed radiological or surgical intervention. Morbidity, mortality, and wound infection rates were 29.0, 2.6, and 13.4 %, respectively. Preoperative serum protein concentration was the only independent risk factor for anastomotic leak (p < 0.0001, OR 0.6 per g/dL). When considering only clinically relevant anastomotic leaks, stapled technique (p = 0.03, OR 2.1) and preoperative serum protein concentration (p = 0.004, OR 0.6 g/dL) were identified as the only two independent risk factors. Age and preoperative serum albumin concentration resulted to be risk factors for postoperative mortality. Male gender, pulmonary or hepatic disease, and open surgical approach were identified as risk factors for postoperative morbidity, while male gender, obesity, intraoperative complication, and end-to-end anastomosis were risk factors for wound infection. CONCLUSIONS Preoperative nutritional status and the stapled anastomotic technique were the only independent risk factors for clinically relevant anastomotic leak after elective right colectomy for cancer. Age and preoperative nutritional status determined the mortality risk, while laparoscopic approach reduced postoperative morbidity.

Abstract
BACKGROUND Stapled technique for ileocolic anastomosis is largely supported in previous studies. However, standard anastomotic configuration is not conclusive and studies are limited. This study aims to compare postoperative outcomes between side to side (S-S) and end to side (E-S) stapled anastomosis after laparoscopic right hemicolectomy underenhanced recovery program (ERP). METHODS Between October 2009 and November 2012, 89 patients (46 in S-S group, 43 in E-S group) who underwent laparoscopic right hemicolectomy for colon cancer and managed with ERP were included in the study. Recovery time and cumulative recovery rates, the length of hospital stays, complication rates were analyzed to compare both configurations. RESULTS The recovery time were not different between groups (S-S group, 135 hours [84-183.5] vs E-S group, 117 hours [94-143]; P = 0.349). Difference of cumulative recovery rates were observed in postoperative day 7 (S-S group, 71.7 % vs E-S group, 93.0 %; P = 0.019). The postoperative hospital stay were shorter in E-S group (S-S, 7 days [6-9] vs E-S, 6 days [5-7]; P = 0.003). The overall complication rates were lower in E-S group (26.1 % vs 4.6 %; P = 0.008). Anastomotic leakage was not observed in both groups. CONCLUSIONS E-S configuration after laparoscopic right hemicolectomy showed favorable outcomes under enhanced recovery program.
