Impact of laparoscopic surgery on short-term and long-term outcomes in elderly obese patients with colon cancer. Ann Gastroenterol Surg 2023; 7:757-764. [PMID: 37663960 PMCID: PMC10472405 DOI: 10.1002/ags3.12678] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 02/15/2023] [Accepted: 04/03/2023] [Indexed: 09/05/2023] Open
Abstract
Background Laparoscopic surgery is reported to be useful in obese or elderly patients with colon cancer, who are at increased risk of postoperative complications because of comorbidities and physical decline. However, its usefulness is less clear in patients who are both elderly and obese and may be at high risk of complications. Methods Data for obese patients (body mass index ≥25) who underwent laparoscopic or open surgery for stage II or III colon cancer between January 2009 and December 2013 were collected by the Japan Society of Laparoscopic Colorectal Surgery. Surgical outcomes, postoperative complications, and relapse-free survival (RFS) were compared between patients who underwent open surgery and those who underwent laparoscopic surgery according to whether they were elderly (≥70 y) or nonelderly (<70 y). Results Data of 1549 patients (elderly, n = 598; nonelderly, n = 951) satisfied the selection criteria for analysis. Length of stay was shorter and surgical wound infection was less common in elderly obese patients who underwent laparoscopic surgery than in those underwent open surgery. There were no significant between-group differences in overall complications, anastomotic leakage, ileus/small bowel obstruction, or RFS. There were also no significant differences in RFS after laparoscopic surgery according to patient age. Conclusion Laparoscopic surgery is safe in elderly obese patients with colon cancer and does not worsen their prognosis. There was no significant difference in the effectiveness of laparoscopic surgery between obese patients who were elderly and those who were nonelderly.

Safety and efficacy of totally minimally invasive right colectomy in the obese patients: a multicenter propensity score-matched analysis. Updates Surg 2022; 74:1281-1290. [PMID: 35639279 PMCID: PMC9338133 DOI: 10.1007/s13304-022-01298-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Accepted: 05/09/2022] [Indexed: 11/25/2022]
Abstract
Despite the well-known benefits of the minimally invasive approach for the right colon cancer treatment, less is known about its feasibility and advantages in morbid obese patients. The aim of this study is to compare the postoperative outcomes after totally minimally invasive right colectomy between the obese and non-obese population. Data derived from a prospectively maintained multicenter colorectal database were analysed, dividing the enrolled patients into two groups: obese (BMI > 29.99) patient group and non-obese patient group. Data about gender, age, American Society of Anesthesiologists (ASA) Score, tumor characteristics, operative time, anastomosis time, extraction site, incision length, intraoperative complications, postoperative complications, postoperative recovery, specimen length and retrieved nodes were taken to assess the achievement of the oncologic standards. After a propensity score matching, a total of 184 patients was included, 92 in each group. No differences were found in terms of demographic data and tumor characteristics. Intraoperative data showed a significant difference in terms of anastomosis time in favour of non-obese group (p < 0.0001). No intraoperative complications were recorded and no conversion was needed in both groups. No differences were found in terms of postoperative complications. There were no differences in terms of first mobilization (p = 0.745), time to first flatus (p = 0.241) time to tolerance to liquid and solid diet (p = 0.241 and p = 0.06) and length of hospital stay (p = 0.817). The analysis of oncologic outcomes demonstrated adequate results in both groups. The results obtained by our study confirmed the feasibility and safety of the totally minimally invasive approach even in obese population.

Predictors of Long-Term Outcomes of Video-Laparoscopic Versus Open Surgery in Obese Patients with Colorectal Cancer: A Propensity Score Matching Study. Cancers (Basel) 2022; 14:cancers14112669. [PMID: 35681648 PMCID: PMC9179295 DOI: 10.3390/cancers14112669] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2022] [Revised: 05/25/2022] [Accepted: 05/26/2022] [Indexed: 02/05/2023] Open
Abstract
Background: Minimally invasive methods in colorectal surgery offer unquestionable advantages, especially in the context of obesity. The current study addresses the lack of scientific evidence on the long-term oncologic safety of video-laparoscopic (VL) approaches in excess-weight CRC patients undergoing surgery. Methods: We retrospectively analyzed a surgical database consisting of 138 CRC patients undergoing VL (n = 87, 63%) and open CRC surgery (n = 51, 37%). To reduce selection bias, a propensity score matching was applied as a preliminary step to balance the comparison between the two surgery groups, i.e., VL and open surgery. Data from patients treated by the same surgeon were used.to minimize bias. Additional Cox regression models were run on the matched sample (N = 98) to explore the observed benefits of VL surgery in terms of overall and cancer-free survival. The nonparametric Kaplan-Meier method was used to compare the two surgical approaches and assess the likelihood of survival and cancer relapse. Results: The study sample was mostly male (N = 86, 62.3%), and VL outnumbered open surgery (63% versus 37%). Both before and after the matching, the VL-allocated group showed better overall survival (p < 0.01) with comparable cancer-free survival over more than five years of median observation time (66 months). Kaplan Meier survival probability curves corroborated the VL significant protective effect on survival (HR of 0.32; 95% CI: 0.13 to 0.81) even after adjusting for major confounding factors (age, gender, comorbidity index, BMI, tumor localization, tumor staging, tumor grading, clearance, CRM). Findings on oncologic performance by tumor relapse were comparable but lacked significance due to the small number of events observed. Conclusions: Comparing CRC surgical approaches, VL allocation showed comparable cancer-free survival but also a better performance on overall mortality than open surgery over more than five years of median observation.

Abstract
PURPOSE To assess the incidence of incisional hernia (IH) across various type of incisions in colorectal surgery (CS) creating a map of evidence to define research trends, gaps and areas of future interest. METHODS Systematic review of PubMed and Scopus from 2010 onwards. Studies included both open (OS) and laparoscopic (LS). The primary outcome was incidence of IH 12 months after index procedure, secondary outcomes were the study features and their influence on reported proportion of IH. Random effects models were used to calculate pooled proportions. Meta-regression models were performed to explore heterogeneity. RESULTS Ninetyone studies were included reporting 6473 IH. The pooled proportions of IH for OS were 0.35 (95% CI 0.27-0.44) I2 0% in midline laparotomies and 0.02 (95% CI 0.00-0.07), I2 52% for off-midline. In case of LS the pooled proportion of IH for midline extraction sites were 0.10 (95% CI 0.07-0.16), I2 58% and 0.04 (95% CI 0.03-0.06), I2 86% in case of off-midline. In Port-site IH was 0.02 (95% CI 0.01-0.04), I2 82%, and for single incision surgery (SILS) of 0.06-95% CI 0.02-0.15, I2 81%. In case of stoma reversal sites was 0.20 (95% CI 0.16-0.24). CONCLUSION Midline laparotomies and stoma reversal sites are at high risk for IH and should be considered in research of preventive strategies of closure. After laparoscopic approach IH happens mainly by extraction sites incisions specially midline and also represent an important area of analysis.

Abstract
INTRODUCTION The impact of obesity on short-term outcomes after laparoscopic colorectal surgery (LAC) in Asian patients is unclear. The purpose of the present multicenter study was to evaluate the safety and feasibility of LAC in obese Japanese patients. METHODS We retrospectively reviewed 1705 patients who underwent LAC between April 2016 and February 2019. Patients were classified according to body mass index (BMI): non-obese (BMI < 25 kg/m2 , n = 1335), obese I (BMI 25-29.9 kg/m2 , n = 313), and obese II (BMI ≥30 kg/m2 , n = 57). Clinical characteristics and surgical outcomes were compared among the three groups. RESULTS The proportion of patients with comorbidities (non-obese, 58.1%; obese I, 69.6%; obese II, 75.4%; P < .001) and median operation time (non-obese, 224 minutes; obese I, 235 minutes; obese II, 258 minutes; P = .004) increased significantly as BMI increased. The conversion rate was similar among the groups (P = .715). Infectious complications were significantly high in obese II patients (non-obese, 10.4%; obese I, 8.3%; obese II, 28.1%; P < .001). Multivariate analysis revealed that in obese II patients, BMI was an independent predictive factor of infectious postoperative complications (odds ratio 2.648; 95% confidence interval, 1.421-4.934; P = .002). CONCLUSION LAC has an increased risk of postoperative infectious complications in obese II patients, despite improvements in surgical technique. Management of obese II colorectal cancer patients requires meticulous perioperative management.

Abstract
AIM To compare long- and short-term outcomes of laparoscopic surgery with those of open surgery for patients with colorectal cancer and body mass index over 25 kg/m2 Patients and Methods: This multicentre, retrospective study analysed clinical records and identified 178 patients with body mass index over 25 kg/m2 who underwent surgery for colon and rectosigmoid cancer between 2000 and 2016. After applying propensity score matching, 96 patients were finally included. The primary outcome was the 3-year recurrence-free survival rate, and the secondary outcomes were short-term results during and after surgery. RESULTS The 3-year recurrence-free survival rates were similar for the laparoscopic and open surgery groups. The laparoscopic surgery group had longer operative times but less blood loss and shorter periods of hospital stay. There were no differences in incidence of postoperative complications. CONCLUSION Laparoscopic and open surgeries had similar long-term outcomes for obese patients. Laparoscopic surgery is an effective option for this population.

Abstract
Simple Summary Extended evidence on minimally invasive surgery in colorectal cancer (CRC) settings is needed, especially as applied to obese patients. We aimed to explore and compare postoperative outcomes between open and video-laparoscopic (VL) surgery in two groups of obese patients undergoing surgical resection for CRC. VL surgery was found to reduce postoperative recovery time and the severity of complications. This Italian experience provides a further contribution to the short-term prognostic quality of minimally invasive VL surgery in obese patients. Abstract Background: Minimally invasive surgery in obese patients is still challenging, so exploring one more item in this research field ranks among the main goals of this research. We aimed to compare short-term postoperative outcomes of open and video-laparoscopic (VL) approaches in CRC obese patients undergoing colorectal resection. Methods: We performed a retrospective analysis of a surgical database including 138 patients diagnosed with CRC, undergoing VL (n = 87, 63%) and open (n = 51, 37%) colorectal surgery. As a first step, propensity score matching was performed to balance the comparison between the two intervention groups (VL and open) in order to avoid selection bias. The matched sample (N = 98) was used to run further regression models in order to analyze the observed VL surgery advantages in terms of postoperative outcome, focusing on hospitalization and severity of postoperative complications, according to the Clavien–Dindo classification. Results: The study sample was predominantly male (N = 86, 62.3%), and VL was more frequent than open surgery (63% versus 37%). The two subgroup results obtained before and after the propensity score matching showed comparable findings for age, gender, BMI, and tumor staging. The specimen length and postoperative time before discharge were longer in open surgery (OS) patients; the number of harvested lymph nodes was higher than in VL patients as well (p < 0.01). Linear regression models applied separately on the outcomes of interest showed that VL-treated patients had a shorter hospital stay by almost two days and about one point less Clavien–Dindo severity than OS patients on average, given the same exposure to confounding variables. Tumor staging was not found to have a significant role in influencing the short-term outcomes investigated. Conclusion: Comparing open and VL surgery, improved postoperative outcomes were observed for VL surgery in obese patients after surgical resection for CRC. Both postoperative recovery time and Clavien–Dindo severity were better with VL surgery.

Laparoscopic Versus Open Emergent Sigmoid Resection for Perforated Diverticulitis. J Gastrointest Surg 2020; 24:1173-1182. [PMID: 31845141 DOI: 10.1007/s11605-019-04490-9] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2019] [Accepted: 11/23/2019] [Indexed: 01/31/2023]
Abstract
BACKGROUND Potential advantages of laparoscopic sigmoidectomy for perforated diverticulitis are still under consideration. This study is designed to determine if emergent laparoscopic sigmoidectomy for perforated diverticulitis is associated with outcomes comparable to the traditional open approach. METHODS The American College of Surgeons-National-Surgical-Quality-Improvement-Program (ACS-NSQIP) database was queried for laparoscopic and open emergent sigmoidectomy cases for perforated diverticulitis from 2012 through 2017. Using propensity score weights, 30-day outcomes between laparoscopic and open approaches were compared in two ways: one with converted cases as a separate group and another with converted cases combined with the laparoscopic-completed group (intention-to-treat). RESULTS A total of 3756 cases met inclusion criteria-282 laparoscopic-completed, 175 laparoscopic-converted-to-open, and 3299 open. The laparoscopic-completed approach had significantly better outcomes than open and laparoscopic-converted cases. When combining laparoscopic-completed and laparoscopic-converted cases (intention-to-treat), the laparoscopic approach still had significantly fewer complications per patient, less unplanned intubation (p = 0.01), and acute renal failure (p = 0.005) than the open group. Laparoscopic groups had longer operating times and shorter hospital length of stay than the open group. Subgroup analysis comparing laparoscopic and open Hartmann's procedure and primary anastomosis with and without diverting stoma also showed favorable outcomes for the laparoscopic group. CONCLUSIONS Laparoscopic emergent sigmoid resection for perforated diverticulitis is associated with favorable outcomes compared to the open approach. Hartmann's procedure is still common and conversion rate is high. Training efforts that increase adoption of minimally invasive surgery and decrease conversion rates are justified. Randomized trials comparing laparoscopic and open approaches may allow further critical assessment of these findings.

Abstract
BACKGROUND Incisional hernia and adhesional intestinal obstruction are important complications of laparoscopic and open resection for colorectal cancer. This is the largest systematic review of comparative studies on this topic. OBJECTIVE This study aimed to investigate whether laparoscopic surgery decreases the incidence of incisional hernia and adhesional intestinal obstruction compared to open surgery for colorectal cancer. DATA SOURCES Online databases PubMed, EMBASE, and the Cochrane Library were searched. Abstracts from the annual meetings of the American Society of Colon and Rectal Surgeons and the European Society of Coloproctology were performed to cover gray literature. STUDY SELECTION We included both randomized and nonrandomized comparative studies. INTERVENTIONS Laparoscopic resection was compared to open resection for patients with colorectal cancer. MAIN OUTCOMES MEASURES The primary outcomes measured were incisional hernia and adhesional intestinal obstruction. RESULTS Fifteen studies met inclusion criteria (6 randomized comparative studies/9 nonrandomized comparative studies); 84,172 patients. Meta-analysis showed decreased odds of developing incisional hernia in the laparoscopic cohort (OR, 0.79; 95% CI, 0.66-0.95; p = 0.01) but no difference in requirement for surgery (OR, 1.07; 95% CI, 0.64-1.79; p = 0.79). Similarly, there were decreased odds of developing adhesional intestinal obstruction in the laparoscopic cohort (OR, 0.81; 95% CI, 0.72-0.92, p = 0.001), but no difference in requirement for surgery (OR, 0.84; 95% CI, 0.53-1.35; p = 0.48). LIMITATIONS Incisional hernia and adhesional intestinal obstruction were poorly defined in many studies. CONCLUSION Laparoscopic surgery is associated with decreased odds of incisional hernias and adhesional intestinal obstructions compared with open surgery for colorectal cancer.

Abstract
The aim of this study was to identify patients undergoing colorectal cancer (CRC) resection who might benefit specifically from either an open or laparoscopic approach. From the NSQIP database (2012–2013), patients who underwent laparoscopic colectomy (LC) or open colectomy (OC) for CRC were identified. The two groups were matched and compared in terms of any, medical, and surgical complications. A wide range of patient characteristics were collected and analyzed. Interaction analysis was performed in a multivariable regression model to identify risk factors that may make LC or OC more beneficial in certain subgroups of patients. Overall, OC (n = 6593) was associated with a significantly higher risk of any [odds ratio (OR) 2.03, 95% confidence interval (CI) 1.87–2.20], surgical (OR 1.98, 95% CI 1.82–2.16), and medical (OR 1.71, 95% CI 1.51–1.94) complications than LC (n = 6593). No subgroup of patients benefited from an open approach. Patients with obesity (BMI > 30) (P = 0.03) and older age (>65 years) (P = 0.01) benefited more than average from a laparoscopic approach. For obese patients, LC was associated with less overall complications (OC vs LC: OR 1.92 obese vs 1.21 nonobese patients). For elderly patients, LC was more preferable regarding the risk of medical complications (OC vs LC OR of 1.91 vs 1.34 for younger patients). No subgroup of CRC patients benefited specifically more from an open colorectal resection. This supports that the laparoscopic technique should be performed whenever feasible. For the obese and elderly patients, the benefits of the laparoscopic approach were more pronounced.

Abstract
BACKGROUND Obesity is generally reported to increase the risk of surgical complications. There have been few reports of laparoscopic hepatectomy (LH) in obese patients. The purpose of this study was to compare the safety and efficacy of (1) LH versus open hepatectomy (OH) in obese patients and (2) LH in obese patients versus LH in non-obese patients. METHODS We introduced LH at our institution in April 2014. LH was performed in 63 obese patients and 108 non-obese patients from April 2014 to May 2017. OH was performed in 79 obese patients from January 2010 to May 2017. This study retrospectively compared the short-term outcomes of the LH obese group with those of the OH obese group and the LH non-obese group. RESULTS In patient characteristics, the LH obese group included a significantly higher percentage of patients with liver cirrhosis than the OH obese group. The LH obese group had fewer patients with a history of abdominal surgery but more with liver cirrhosis than the LH non-obese group. For short-term outcomes, the LH obese group had significantly less blood loss, fewer intraoperative transfusions, fewer positive surgical margins, and shorter postoperative hospital stays than the OH obese group. In contrast, only operation time was significantly different (longer) in the LH obese group than in the LH non-obese group. There were no significant differences in morbidity or mortality between the LH obese group and either the OH obese or the LH non-obese groups. CONCLUSION LH in obese patients is safe and effective.

Abstract
PURPOSE Previous studies have demonstrated that obese patients (BMI >30) undergoing laparoscopic colectomy have longer operative times and increased complications when compared to non-obese cohorts. However, there is little data that specifically evaluates the outcomes of obese patients based on the degree of their obesity. The aim of this study was to evaluate the impact of increasing severity of obesity on patients undergoing laparoscopic colectomy. METHODS A retrospective review was performed of all patients undergoing laparoscopic colectomy between 1996 and 2013. Patients were classified according to their BMI as obese (BMI 30.0-39.9), morbidly obese (BMI 40.0-49.9), and super obese (BMI >50). Main outcome measures included conversion rate, operative time, estimated blood loss, post-operative complications, and length of stay. RESULTS There were 923 patients who met inclusion criteria. Overall, 604 (65.4%), 257 (27.9%), and 62 (6.7%) were classified as obese (O), morbidly obese (MO), and super obese (SO), respectively. Clinicopathologic characteristics were similar among the three groups. The SO group had significantly higher conversion rates (17.7 vs. 7 vs. 4.8%; P = 0.031), longer average hospital stays (7.1 days vs. 4.9 vs. 3.4; P = 0.001), higher morbidity (40.3 vs. 16.3 vs. 12.4%; P = 0.001), and longer operative times (206 min vs. 184 vs. 163; P = 0.04) compared to the MO and O groups, respectively. The anastomotic leak rate in the SO (4.8%; P = 0.027) and MO males (4.1%; P = 0.033) was significantly higher than MO females (2.2%) and all obese patients (1.8%). CONCLUSION Increasing severity of obesity is associated with worse perioperative outcomes following laparoscopic colectomy.

Abstract
Laparoscopic colorectal surgery has now become widely adopted for the treatment of colorectal neoplasia, with steady increases in utilization over the past 15 years. Common minimally invasive techniques include multiport laparoscopy, single-incision laparoscopy, and hand-assisted laparoscopy, with the choice of technique depending on several patient and surgeon factors. Laparoscopic colorectal surgery involves a robust learning curve, and fellowship training often lays the foundation for a high-volume laparoscopic practice. This article provides a summary of the various techniques for laparoscopic colorectal surgery, including operative steps, the approach to difficult patients, and the learning curve for proficiency.

Abstract
During the 1990s, laparoscopic resection was established as a treatment for gastrointestinal malignant tumors. A number of randomized controlled trials comparing laparoscopic-assisted colorectal surgery with conventional open colorectal surgery for colon cancer have been conducted. These trials have shown short-term benefits, and the vast majority demonstrated no significant difference in long-term outcomes. Laparoscopic-assisted colorectal surgery is widely performed for the treatment of colon cancer, whereas laparoscopic-assisted colorectal surgery for rectal cancer is less commonly performed. In recent years, there have been an increasing number of reports of laparoscopic-assisted colorectal surgery for rectal cancer, where improving short-term outcomes was shown, but no definitive effect on long-term survival has been shown to date. Randomized controlled trials focusing on long-term survival are currently ongoing.

Abstract
OBJECTIVE This study aimed to evaluate the effect of obesity on surgical outcomes in patients who underwent gynecologic surgery. MATERIALS AND METHODS In total, we evaluated 132 patients who underwent total abdominal hysterectomy with or without salpingo-oophorectomy for benign gynecologic procedures at our tertiary referral gynaecology clinic. RESULTS The non-morbid obese group [body mass index (BMI) <40 kg/m2] included 94 patients, and the morbid obese group (BMI ≥40 kg/m2) included 38 patients. The perioperative outcomes of the groups were compared. The mean operative time was significantly longer for morbid obese patients than non-morbid obese patients (p<0.05). Estimated blood loss, the need for blood transfusion, postoperative hemoglobin values, and the need for an intraabdominal drain were similar between the groups. Early and late postoperative complications were significantly more frequent in the morbid obese group than the other group (p<0.05, for each). Early postoperative complications in patients who underwent vertical skin incision were significantly more frequent than in patients who underwent pfannenstiel incision (p<0.05). Late complications were comparable between the two types of skin incision. CONCLUSION Morbid obesity significantly increases the mean operative times and the postoperative complication rates of abdominal hysterectomy operations.

Predicting opportunities to increase utilization of laparoscopy for colon cancer. Surg Endosc 2016; 31:1855-1862.

Abstract
BACKGROUND Despite proven safety and efficacy, rates of minimally invasive approaches for colon cancer remain low in the USA. Given the known benefits, investigating the root causes of underutilization and methods to increase laparoscopy is warranted. Our goal was to develop a predictive model of factors impacting use of laparoscopic surgery for colon cancer. METHODS The Premier Hospital Database was reviewed for elective colorectal resections for colon cancer (2009-2014). Patients were identified by ICD-9-CM diagnosis code and then stratified into open or laparoscopic approaches by ICD-9-CM procedure codes. An adjusted multivariate logistic regression model identified variables predictive of use of laparoscopy for colon cancer. RESULTS A total of 24,245 patients were included-12,523 (52 %) laparoscopic and 11,722 (48 %) open. General surgeons performed the majority of all procedures (77.99 % open, 71.60 % laparoscopic). Overall use of laparoscopy increased from 48.94 to 52.03 % over the study period (p < 0.0001). Patients with private insurance were more likely to have laparoscopy compared with Medicare patients (adjusted odds ratio (OR) 1.089, 95 % CI [1.004, 1.181], p = 0.0388). Higher volume of surgeons (OR 3.518, 95 % CI [2.796, 4.428], p < 0.0001) and larger hospitals by bed size were more likely to approach colon cancer laparoscopically. Colorectal surgeons were 32 % more likely to approach a case laparoscopically than general surgeons (OR 1.315, 95 % CI [1.222, 1.415], p < 0.0001). Teaching hospitals, hospitals in the Midwest, and hospitals with less than 500 beds were less likely to use laparoscopy. CONCLUSIONS There are patient, provider, and hospital characteristics that can be identified preoperatively to predict who will undergo surgery for colon cancer using laparoscopy. However, additional patients may be eligible for laparoscopy based on patient-level characteristics. These results have implications for regionalization and increasing teaching of MIS. Recognizing and addressing these variables with training and recruiting could increase use of minimally invasive approaches, with the associated clinical and financial benefits.

Abstract
BACKGROUND While the prevalence of obesity in IBD patients is rapidly increasing, it is unclear if obesity impacts surgical outcomes in this population. We aim to investigate the effects of BMI on perioperative and postoperative outcomes in IBD patients by stratifying patients into BMI groups and comparing outcomes between these groups. METHODS This is a retrospective cohort study where IBD patients who underwent intestinal surgeries between the years of 2000 to 2014 were identified. The patients were divided into groups based on BMI: underweight (BMI <18.5), normal weight (BMI 18.5-24.9), overweight (BMI 25-29.9), and obese (BMI ≥30). Preoperative patient demographics, operative variables, and postoperative complications were collected and compared between BMI groups. RESULTS A total of 391 surgeries were reviewed (34 underweight, 187 normal weight, 105 overweight, and 65 obese) from 325 patients. No differences were observed in preoperative patient demographics, type of IBD, preoperative steroid or biologic mediator use, or mean laboratory values. No differences were observed in percent operative procedures with anastomosis, surgeries converted to open, estimated blood loss, intraoperative complications, and median operative time. Thirty-day postoperative complication rates including total complications, wound infection, or anastomotic leak were similar between groups. There was a statistically significant increased postoperative bleeding risk (p = 0.029) in underweight patients. The relative percent for increased postoperative bleeding risk between BMI groups was as follows: 2.9% in underweight, zero in normal weight, 2.9% in overweight, and zero in obese. CONCLUSION Obesity does not appear to impact intraoperative variables nor does obesity appear to worsen postoperative complication rates in IBD patients.

Abstract
BACKGROUND Obesity has been associated with worse postoperative outcomes than those for normal weight. Data on the short-term results of laparoscopic liver resection (LLR) in patients with obesity are scarce. Furthermore, the long-term outcomes of LLR versus open liver resection (OLR) have not been adequately assessed. The aims of this study were to analyze the outcomes of obese patients undergoing LLR and to compare these to the outcomes of obese patients undergoing OLR. METHODS Data regarding the short-term results from 13 obese patients who underwent laparoscopic non-anatomical liver resection were retrospectively compared with the data from 69 obese patients who underwent open non-anatomical liver resection between 2002 and 2012. The long-term results of patients with hepatocellular carcinoma were also compared. RESULTS A total of 82 patients who underwent non-anatomical liver resection in our institution were included. There were no differences between the two groups in terms of preoperative patient characteristics. The intraoperative blood loss in the laparoscopic group was significantly less than that in the open group. There were no significant differences in the postoperative complications or postoperative mortality. The postoperative hospital stay of the laparoscopic group was significantly shorter than that of the open group. CONCLUSIONS LLR in obese patients results in decreased intraoperative blood loss and shorter postoperative hospital stays compared with OLR. When performed in selected patients, LLR may be a safe and feasible option for obese patients.

Abstract
OBJECTIVE The objectives of this paper were to establish a model for the conversion of laparoscopic rectal resection to open surgery and to predict possible conversion before surgery. METHODS The clinical data of 602 cases of laparoscopic rectal resection were retrospectively assessed. Risk factors associated with conversion of laparoscopic rectal resection to open rectal surgery were identified by logistic regression analysis. Also, a scoring system was created to calculate a score for the conversion of laparoscopic rectal resection to predict possible conversion for patients who underwent laparoscopic rectal resection before surgery. RESULTS A total of 90 patients required conversion (total conversion rate = 14.95%). The established model included six variables: male gender, surgical experience (≤25 cases), history of abdominal surgery, body mass index ≥ 28, tumor diameter ≥ 6 cm, and tumor invasion or metastasis, for which 6, 4, 5, 10, 15, and 21 points were assigned, respectively. A patient with a total score >14.5 points was considered to have a high probability of conversion, whereas a patient with a total score <14.5 points was considered at a low risk. CONCLUSION Preoperative determination of conversion score may predict possible conversion of laparoscopic rectal resection and thus reduce unnecessary open rectal surgery.

Abstract
An elevated body mass index (BMI) is associated with increased morbidity and mortality after colorectal surgery. While coexistent comorbid conditions are captured in some determinations of case-severity, BMI itself is not factored into pay for performance (P4P) initiatives. From the National Surgical Quality Improvement Program database 2006-2011, obese (BMI ≥30 kg/m(2)) and nonobese (BMI <30 kg/m(2)) patients with and without comorbidity undergoing colorectal resection were identified. Pre- and intraoperative factors as well as postoperative outcomes were compared. Of 130,415 patients, 31.3 % were obese. 80.4 % of obese and 72.9 % of nonobese patients had comorbid conditions. Among obese patients, overall rates of surgical site infection (SSI), wound dehiscence, and various medical complications were significantly higher for those with comorbidity compared to those without (p < 0.001 for all). Obese patients with comorbidity overall had greater risk of renal failure and urinary tract infection than nonobese patients. Regardless of comorbidity, obese patients more commonly had pulmonary embolism, failure to wean from the ventilator, overall SSI, and wound dehiscence. Comorbid factors associated with obesity influence outcomes; however, obesity itself in their absence is associated with worse outcomes. This supports inclusion of obesity as an independent determinant of case-severity, quality, and reimbursement after colorectal surgery.

Abstract
BACKGROUND Laparoscopic colectomy has been associated with favorable outcomes when compared to open colectomy. Single-Incision Robotic Colectomy (SIRC) is a novel procedure hypothesized to improve upon conventional three-port laparoscopic colectomy. We hereby present and analyze our institution's initial experience with SIRC. METHODS We performed a retrospective review of 59 patients who underwent SIRC between May 2010 and September 2013, attempting to identify factors associated with conversion rate and postoperative complication rate. RESULTS Our study included 34 males (57.6%) and 25 females (42.4%). The mean age was 60.3 years (range 29-92 years), and the mean BMI was 26.6 kg/m(2) (range 14.9-39.7 kg/m(2)). We identified 31 right hemicolectomies (53.4%), 20 sigmoid colectomies (34.5%), 5 left hemicolectomies (1.7%), 2 low anterior resections (3.5%), and 1 total colectomy (1.7%). The overall median operative time was 188 min with an interquartile range of 79 min. Surgical indications included diverticulitis (n = 23, 39.0%), benign colonic mass (n = 18, 30.5%), colon cancer (n = 16, 27.1%), familial adenomatous polyposis (n = 1, 1.7%), and Crohn's disease (n = 1, 1.7%). There were four conversions to open procedure (6.8%), three conversions to multiport robotic procedure (5.1%), and one conversion to single-port laparoscopic procedure (1.7%). Reasons for conversions include difficulty mobilizing the colon and robotic equipment malfunction. Conversions were associated with both higher complication rates (62.5 vs 25.5%, p = 0.035) and longer LOS (7.4 vs 4.0 days, p = 0.0003). Postoperative complications occurred in 16 of the 59 cases (27.1%). Higher BMI was the only significant risk factor for postoperative complications. The overall median LOS was 4 ± 2 days, while the median estimated blood loss was 100 ± 90 ml. CONCLUSIONS Our experience has shown that SIRC can be a safe and feasible procedure for both benign and malignant disease. Patient selection is the key to improving surgical outcomes in SIRC.

Laparoscopic versus open Ladd's procedure for intestinal malrotation in adults. Surg Endosc 2014; 29:1598-604. [PMID: 25294535 DOI: 10.1007/s00464-014-3849-3] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2014] [Accepted: 08/15/2014] [Indexed: 12/18/2022]
Abstract
BACKGROUND Intestinal malrotation results from errors in fetal intestinal rotation and fixation. While most patients are diagnosed in childhood, some present as adults. Laparoscopic Ladd's procedure is an accepted alternative to laparotomy in children but has not been well-studied in adults. This study was designed to investigate outcomes for adults undergoing laparoscopic Ladd's repair for malrotation. METHODS We performed a single-institution retrospective chart review over 11 years. Data collected included patient age, details of pre-operative work-up and diagnosis, surgical management, complications, rates of re-operation, and symptom resolution. Patients were evaluated on an intent-to-treat basis based on their planned operative approach. Categorical data were analyzed using Fisher's exact test. Continuous data were analyzed using Student's t test. RESULTS Twenty-two patients were identified (age range 18-63). Fifteen were diagnosed pre-operatively; of the remaining seven patients, four received an intra-operative malrotation diagnosis during elective surgery for another problem. Most had some type of pre-operative imaging, with computed tomography being the most common (77.3 %). Comparing patients on an intent-to-treat basis, the two groups were similar with respect to age, operative time, and estimated blood loss. Six patients underwent successful laparoscopic repair; three began laparoscopically but were converted to laparotomy. There was a statistically significant difference in hospital length of stay (LOS) (5.0 ± 2.5 days vs 11.6 ± 8.1 days, p = 0.0148) favoring the laparoscopic approach. Three patients required re-operation: two underwent side-to-side duodeno-duodenostomy and one underwent a re-do Ladd's procedure. Ultimately, three (two laparoscopic, one open) had persistent symptoms of bloating (n = 2), constipation (n = 2), and/or pain (n = 1). CONCLUSION Laparoscopic repair appears to be safe and effective in adults. While a small sample size limits the power of this study, we found a statistically significant decrease in LOS and a trend toward decreased postoperative nasogastric decompression. There were no significant differences in complication rates, re-operation, or persistence of symptoms between groups.
