RESUMEN

OBJECTIVE: To evaluate causes and predictors of readmission after new ileostomy creation. BACKGROUND: New ileostomates have been reported to have higher readmission rates compared with other surgical patients, but data on predictors are limited. METHODS: A total of 1114 records at 2 associated hospitals were reviewed to identify adults undergoing their first ileostomy. Primary outcome was readmission within 60 days of surgery. Multiple logistic regression was used to identify independent predictors; area under the receiver-operator characteristic curves (AUC) were used to evaluate age-stratified models in secondary analysis. RESULTS: In all, 407 patients underwent new ileostomy; 58% had cancer, 31% IBD; 49% underwent LAR, 27% colectomy, and 14% proctocolectomy. Median length of stay was 8 days. Among the patients, 39% returned to hospital, and 28% were readmitted (n = 113) at a median of 12 days postdischarge. The most common causes of readmission were dehydration (42%), intraperitoneal infections (33%), and extraperitoneal infections (29%). Dehydration was associated with later, longer, and repeated readmission. Independent significant predictors of readmission were Clavien-Dindo complication grade 3 to 4 [odds ratio (OR) 6.7], Charlson comorbidity index (OR 1.4 per point), and loop stoma (OR 2.2); longer length of stay (OR 0.5) and age 65 years or older (OR 0.4) were protective. Cohort stratification above or below age 65 revealed that older patient readmissions were more predictable (AUC 0.84) with more preventable causes, whereas younger patient readmissions were difficult to predict or prevent (AUC 0.65). CONCLUSIONS: Readmissions are most commonly caused by dehydration, and are predicted by serious complications, comorbidity burden, loop stoma, shorter length of stay, and age. Readmissions in older patients are easier to predict, representing an important target for improvement.

RESUMEN

BACKGROUND: Laparoscopic surgical treatment of T4 cancers remains a concern that is mostly associated with technical feasibility, high conversion rate, inadequate oncologic clearance, and surgical outcome. OBJECTIVE: The purpose of this work was to evaluate the short- and long-term clinical and oncologic outcomes after laparoscopic and open surgeries for T4 colon cancers. DESIGN: This was a retrospective study of patients with T4 colon cancer without metastasis (M0) who had laparoscopic or open surgery from 2003 to 2011. SETTING: The study was conducted at a single institution. PATIENTS: A total of 83 patients with pT4 colon cancer were included. MAIN OUTCOME MEASURES: R0 resection rate, morbidity and mortality within 30 postoperative days, overall survival, and disease-free survival were measured. RESULTS: Laparoscopic surgery was performed on 61 and open surgery on 22 patients. The groups were similar in overall staging (p = 0.461), with 35 (42%) of the patients at stage 2 and 48 (58%) at stage 3. A complete R0 resection was achieved in 61 (100%) of the patients who underwent laparoscopic surgery and in 21 (96%) of the patients who underwent open surgery (p = 0.265). The average number of lymph nodes harvested was 21 in the laparoscopic group and 24 in the open group (p = 0.202). Thirty-day morbidity rate was similar between the groups (p = 0.467), and the mortality rate was 0. The length of hospital and postsurgical stay was significantly shorter in the laparoscopic group (p = 0.002 and p = 0.008). The 3-year overall survival rates between the groups were 82% (range, 71%-93%) for patients who underwent laparoscopic surgery and 81% (range, 61%-100%) for those who underwent open surgery (p = 0.525), and disease-free survival was 67% (range, 54%-79%) for laparoscopic surgery and 64% (range, 43%-86%) for open surgery (p = 0.848). The follow-up time was 40 ± 25 in months in the laparoscopic group and 34 ± 26 months in the open surgery group (p = 0.325). LIMITATIONS: This was a retrospective study at a single institution. CONCLUSIONS: The study shows that laparoscopic surgery is feasible in T4 colon cancers. With comparable clinical and oncologic outcomes, this study suggests that laparoscopy may be considered as an alternative approach for T4 colon cancers with the advantage of faster recovery (see Video, Supplemental Digital Content 1, http://links.lww.com/DCR/A156).

RESUMEN

BACKGROUND: Although interest in sphincter-sparing treatments for anal fistulas is increasing, few large prospective studies of these approaches have been conducted. OBJECTIVE: The study assessed outcomes after implantation of a synthetic bioabsorbable anal fistula plug. DESIGN: A prospective, multicenter investigation was performed. SETTING: The study was conducted at 11 colon and rectal centers. PATIENTS: Ninety-three patients (71 men; mean age, 47 years) with complex cryptoglandular transsphincteric anal fistulas were enrolled. Exclusion criteria included Crohn's disease, an active infection, a multitract fistula, and an immunocompromised status. INTERVENTION: Draining setons were used at the surgeon's discretion. Patients had follow-up evaluations at 1, 3, 6, and 12 months postoperatively. MAIN OUTCOME MEASURES: The primary end point was healing of the fistula, defined as drainage cessation plus closure of the external opening, at 6 and 12 months. Secondary end points were fecal continence, duration of drainage from the fistula, pain, and adverse events during follow-up. RESULTS: Thirteen patients were lost to follow-up and 21 were withdrawn, primarily to undergo an alternative treatment. The fistula healing rates at 6 and 12 months were 41% (95% CI, 30%-52%; total n = 74) and 49% (95% CI, 38%-61%; total n = 73). Half the patients in whom a previous treatment failed had healing. By 6 months, the mean Wexner score had improved significantly (p = 0.0003). By 12 months, 93% of patients had no or minimal pain. Adverse events included 11 infections/abscesses, 2 new fistulas, and 8 total and 5 partial plug extrusions. The fistula healed in 3 patients with a partial extrusion. LIMITATIONS: The study was nonrandomized and had relatively high rates of loss to follow-up. CONCLUSION: Implantation of a synthetic bioabsorbable fistula plug is a reasonably efficacious treatment for complex transsphincteric anal fistulas, especially given the simplicity and low morbidity of the procedure.

RESUMEN

BACKGROUND: CT enterography and magnetic resonance enterography have emerged as first-line imaging technologies for the evaluation of the gastrointestinal tract in Crohn's disease. OBJECTIVE: The purpose of this work was to evaluate the accuracy of these imaging modalities to identify Crohn's disease lesions preoperatively. DESIGN: This was a retrospective chart review. SETTINGS: The study was conducted at a single institution. PATIENTS: Seventy-six patients with Crohn's disease with preoperative CT enterography and/or magnetic resonance enterography were included in the study. MAIN OUTCOME MEASURES: The number of stenoses, fistulas, and abscesses on CT enterography and/or magnetic resonance enterography before surgery were compared with operative findings. RESULTS: Forty patients (53%) were women, 46 (60%) underwent surgery for recurrent Crohn's disease, and 46 (57%) had previous abdominal surgery. Thirty-six (47%) had a preoperative CT enterography and 43 (57%) had a preoperative magnetic resonance enterography. CT enterography sensitivity was 75% for stenosis and 50% for fistula. MRE sensitivity was 68% for stenosis and 60% for fistula. The negative predictive values of CT enterography and magnetic resonance enterography for stenosis were very low (54% and 65%) and were 85% and 81% for fistula. CT enterography had 76% accuracy for stenosis and 79% for fistula; magnetic resonance enterography had 78% accuracy for stenosis and 85% for fistula. Both were accurate for abscess. False-negative rates for CT enterography were 50% for fistula and 25% for stenosis. False-negative rates for magnetic resonance enterography were 40% for fistula and 32% for stenosis. Unexpected intraoperative findings led to modification of the planned surgical procedure in 20 patients (26%). LIMITATIONS: This study was limited by its small sample size, its retrospective nature, and that some studies were performed at outside institutions. CONCLUSIONS: CT enterography and magnetic resonance enterography in patients with Crohn's disease were accurate for the identification of abscesses but not for fistulas or stenoses. Surgeons should search for additional lesions intraoperatively. Patients should be appropriately counseled regarding the need for unexpected interventions (see Video, Supplemental Digital Content 1, http://links.lww.com/DCR/A162).

RESUMEN

OBJECTIVE: The purpose of this study was to identify patient, clinical, and surgical factors that may predispose patients to anastomotic leak (AL) after large bowel surgery. BACKGROUND: Anastomotic leak is still one of the most devastating complications following colorectal surgery. Knowledge about factors predisposing patients to AL is vital to its early detection, decision making for surgical time, managing preoperative risk factors, and postoperative complications. METHODS: This was a prospective observational, quality improvement study in a cohort of 616 patients undergoing colorectal resection in a single institution with the main outcome being AL within 30 days postoperatively. Some of the predictor variables were age, sex, Charlson Comorbidity Index (CCI), radiation and chemotherapy, immunomodulator medications, albumin, preoperative diagnoses, surgical procedure(s), surgical technique (laparoscopic vs open), anastomotic technique (staple vs handsewn), number of major arteries ligated at surgery, surgeon's experience, presence of infectious condition at surgery, intraoperative adverse events, and functional status using 36-Item Short Form General Health Survey. RESULTS: Of the 616 patients, 53.4% were female. The median age of the patients was 63 years and the mean body mass index was 25.9 kg/m. Of them, 80.3% patients had laparoscopic surgery and 19.5% had open surgery. AL occurred in 5.7% (35) patients. In multivariate analysis, significant independent predictors for leak were anastomoses less than 10 cm from the anal verge, CCI of 3 or more, high inferior mesenteric artery ligation (above left colic artery), intraoperative complications, and being of the male sex. CONCLUSIONS: Multiple risk factors exist that predispose patients to ALs. These risk factors should be considered before and during the surgical care of colorectal patients.

RESUMEN

BACKGROUND: Patients with large benign colon polyps not amenable to endoscopic removal commonly undergo resections. Polyp removal using combined endolaparoscopic surgery may be an effective alternative to bowel resection in select patients. OBJECTIVE: The aim of this study was to evaluate short-term and long-term outcomes of patients who underwent endolaparoscopy at our institution. DATA SOURCES: Medical records and a prospectively maintained database were reviewed. STUDY SELECTION: This study constituted a retrospective review of consecutive patients who underwent endolaparoscopy for benign polyps from 2003 to 2012. INTERVENTIONS: Combined endolaparoscopic surgery was performed. MAIN OUTCOME MEASURES: The primary outcomes measured were success rate, rate of recurrence, rate of malignancy, length of stay, and complication rate. RESULTS: A total of 75 patients were taken to the operating room with the intention of endolaparoscopy. The most common indications were large polyp size and difficult location. Based on intraoperative findings, 10 patients were suspected of having cancer and underwent immediate laparoscopic colectomy. Of 65 attempted cases, 48 patients (74%) underwent successful combined endolaparoscopic surgery. Median follow-up time was 65 (8-87) months. Patients in whom combined endolaparoscopic surgery was unsuccessful were converted to colectomy (2 open, 15 laparoscopic). Two patients were converted because of concerns of cancer and 15 because of technical difficulties. Median operative time for successful endolaparoscopy was 145 (50-249) minutes. The complication rate was 4.4% (2/48). Median length of stay was 1 (0-6) day for endolaparoscopy vs 5 (3-19) days for those converted to colectomy. Median polyp size was 3 (1.0-7.0) cm. One patient was found to have cancer on final pathology, but refused to have further surgery. Sensitivity and specificity of predicting malignancy based on clinical findings were 33% (4/12) and 98.5% (64/65). Four of 5 patients who had recurrence (10%) after endolaparoscopy had complete endoscopic polypectomy. One patient required delayed laparoscopic colectomy for a second recurrence. LIMITATIONS: This study was limited by its retrospective nature. CONCLUSIONS: Combined endolaparoscopic surgery appears to be a safe and effective alternative to colectomy in all parts of the colon in patients who have benign polyps not removable with colonoscopy alone.

RESUMEN

Background and Objectives: Despite the growth of minimally invasive surgery (MIS) in many specialties, open colon surgery is still routinely performed. The purpose of this study was to compare outcomes and costs between open colon and minimally invasive colon resections. Methods: We analyzed outcomes between January 1, 2016 and December31, 2018 using the Vizient® clinical database. Demographics, hospital length of stay, readmissions, complications, mortality, and costs were compared between patients undergoing elective open and minimally invasive colon resections. For bivariate analysis, Wilcoxon rank-sum test was used for continuous variables and χ2 test was used for categorical variables. Multiple Logistic and Quintile regression were used for multivariable analyses. Results: A total of 88,405 elective colon resections (open: 56,599; minimally invasive: 31,806) were reviewed. A significantly larger proportion of patients undergoing minimally invasive surgery were obese (body mass index > 30) compared to those undergoing open surgery (71.4% vs. 59.6%; p < 0.0001). As compared to minimally invasive colectomy, open colectomy patients had: a longer median length of stay [median (range): 7 (4-13) days vs. 4 (3 - 6) days, p < 0.0001], higher 30-day readmission rate [n = 8557 (15.1%) vs. 2815 (8.9%), p < 0.0001], higher mortality [n = 2590 (4.4%) vs. 107 (0.34%), p < 0.0001], and a higher total direct cost [median (range): $13,582 (9041-23,094) vs. $9013 (6748 - 12,649), p < 0.0001]. Multivariable models confirmed these findings. Conclusion: Minimally invasive colon surgery has clear benefits in terms of length of stay, readmission rate, mortality and cost, and the routine use of open colon resection should be revaluated.

RESUMEN

BACKGROUND: For complex right colon polyps, not removable using colonoscopy, right colon resection is considered the optimal treatment. Combined endoscopic-laparoscopic surgery, using both laparoscopy and CO2 colonoscopy, has been introduced as a new approach for these complex colon polyps with intent to avoid bowel resection. OBJECTIVE: This study aimed to evaluate the safety and outcomes of combined endoscopic-laparoscopic surgery used for treatment of complex right colon polyps. DESIGN: This is a retrospective study of patients undergoing combined endoscopic-laparoscopic surgery for treatment of benign right colon polyps from 2003 to 2008. SETTINGS: This is a single-institution study. PATIENTS: Twenty-three patients with complex right colon polyps were included. MAIN OUTCOME MEASURES: The main outcome measures included the length of hospital stay, postoperative complications, and polyp recurrence. RESULTS: Of 23 patients, 20 (87%) patients had their polyp removed successfully by combined endoscopic-laparoscopic surgery and 3 (13%) needed laparoscopic resection, after laparoendoscopic evaluation. The median length of hospital stay was 2 days (range, 1-5), and there were no postoperative complications. Median follow-up time was 12 months. Three patients had recurrent polyps, and the recurrence-free interval at 36 months was 55.7% (95% CI = 8.6%, 87.0%). All recurrences were benign polyps and were removed by colonoscopic snaring. CONCLUSIONS: Combined endoscopic-laparoscopic surgery can be safely offered to selected patients with benign right colon polyps that can not be removed by colonoscopy. This combined approach may provide a viable alternative to right colon resection for complex benign colon lesions and warrants future investigation.

RESUMEN

OBJECTIVE: Surgical site infections are a major source of morbidity after colorectal surgery. The aim of this study was to explore differences between incisional and organ/space surgical site infection types by evaluating risk factors, National Nosocomial Risk Index Scores, and clinical outcomes. DESIGN: A random sample of adults undergoing abdominal colorectal surgery between June 2001 and July 2008 was extracted from a colorectal surgery practice database. Patient factors, comorbidities, intraoperative factors, postoperative factors, and infection were collected; risk score (from -1 to 3 points) was calculated. Variables associated with surgical site infection by univariate analysis were incorporated in a multivariable model to identify risk factors by infection type. Infection risk by risk score was evaluated by logistic regression. Length of stay, readmission, and mortality were examined by infection type. RESULTS: Six hundred fifty subjects were identified: 312 were male, age was 59.8 (SD 17.8) years. Common preoperative diagnoses included colorectal cancer (36.9%) and inflammatory bowel disease (21.7%). Forty-five cases were emergencies, and 171 included rectal resections. Eighty-two patients developed incisional and 64 developed organ/space surgical site infections. Body mass index was associated with incisional infection (OR 1.05, 95% CI 1.00-1.09), whereas previous radiation (OR 4.49, 95% CI 1.53-13.18), postoperative hyperglycemia (OR 2.99, 95% CI 1.41-6.34), preoperative [albumin] (OR 0.52, 95% CI 0.36-0.76), and case length (OR 1.26, 95% CI 1.08-1.47) were associated with organ/space infection. A risk score of 2 and above, compared with a score of <2, predicted organ/space (OR 5.92, 95% CI 3.16-11.09) but not incisional infection (OR 0.95, 95% CI 0.41-2.16). Organ/space infections were associated with longer length of stay (P = .006) and higher readmission rates (P < .001) than incisional infections. CONCLUSIONS: Risk factors for surgical site infections differ by type of infection. Clinical outcomes and value of the risk index score are different by infection type. It may be prudent to consider incisional and organ/space surgical site infections as different entities for patients undergoing colorectal surgery.

RESUMEN

BACKGROUND: In recent years, there has been considerable interest in developing technology as well as techniques that could widen the therapeutic horizons of endoscopy. Rectal prolapse, a benign localized condition causing considerable morbidity, could be an excellent focus for new endoscopic therapies. The aim of this study was to assess the feasibility and safety of endoluminal fixation of the rectum to the anterior abdominal wall, after pushing it up inside the body, using an in vivo animal model. METHODS: We performed an in vivo comparative surgical study in a porcine model, including laparoscopic mobilization of the rectum and posterior rectopexy (standard surgical method) or endoluminal tacking of the rectum. After proving feasibility in ex vivo and acute studies, we performed a survival study to evaluate the safety of endoluminal tacking of the mobilized rectum to the anterior abdominal wall. The main outcome measures were successful completion of the tasks, maintenance of the fixation, complications associated with the methods, and survival studies including histopathological examinations of the fixation sites. RESULTS: There were two groups: laparoscopic rectopexy (8 animals) and endoluminal fixation of the rectum to the anterior abdominal wall (10 animals). There were no differences between these two groups in their postoperative recovery. The group with the endoluminal fixation was found to have adequate attachment of the rectum to the anterior abdominal wall (measured attachment pressure in the endoluminal group = 6.06 ± 0.52 ft-lb, in the control group = 4.86 ± 2.00 ft-lb) on both gross and microscopic evaluation. CONCLUSION: Endoscopic fixation of the mobilized rectum is feasible and safe in this model and in the future may provide an effective alternative to current treatment options for rectal prolapse.

RESUMEN

BACKGROUND: The use of intraoperative carbon dioxide (CO(2)) colonoscopy during a laparoscopic colon operation is becoming more common. Simultaneous intracolonic and intraabdominal CO(2) insufflation may result in significant physiologic changes, but in-depth physiologic effects have not been studied to date. This study aimed to evaluate the physiologic changes and the overall safety of simultaneous CO(2) laparoscopy and colonoscopy. METHODS: A prospective pilot study was performed with 26 subjects (17 men and 9 women) undergoing laparoscopic surgical treatment for colorectal conditions adjunctively managed with CO(2) intraoperative colonoscopy. Surgery proceeded with CO(2) insufflation to a maximum pressure of 12 mmHg by laparoscopy and with a maximum CO(2) flow of 5 l/min via colonoscopy. Serial intra- and postoperative arterial blood gases, end-tidal CO(2), and minute ventilation were recorded during predetermined periods: during initial laparoscopy, during simultaneous colonoscopy and laparoscopy, during laparoscopy after colonoscopy, and after desufflation. RESULTS: No significant morbidity resulted from simultaneous CO(2) insufflation. Three patients had a CO(2) partial pressure (PaCO(2)) greater than 50, and one patient with a body mass index (BMI) higher than 42 kg/m(2) had a PaCO(2) greater than 50 for more than 30 min and was compensated by increasing minute ventilation. The mean pH was 7.36 in the recovery room. Postoperatively, no patient had a pH lower than 7.3, prolonged intubation, or reintubation. CONCLUSION: Simultaneous CO(2) colonoscopy and laparoscopy lead only to transient alterations in respiratory parameters that can be compensated. Based on these findings, simultaneous insufflation of CO(2) into the peritoneal cavity and the large bowel lumen during complex endoscopic procedures may be considered safe for most patients.

RESUMEN

BACKGROUND: Although evidence suggests that laparoscopic colectomy (LC) results in faster gastrointestinal (GI) recovery than open bowel resection, previous studies were performed at single institutions or generally not controlled for diet introduction or perioperative care, making the results difficult to interpret. A prospective, observational, multicenter study was planned to investigate GI recovery, length of hospital stay (LOS), and postoperative ileus (POI)-related morbidity after LC. METHODS: Patients scheduled to undergo LC or hand-assisted laparoscopic (HAL) bowel resection and to receive opioid-based postoperative intravenous patient-controlled analgesia were enrolled in 16 U.S. centers. The study design was similar to that for trials of alvimopan phase 3 open laparotomy bowel resection using a standardized accelerated postoperative care pathway. The primary end points were time to upper and lower GI recovery (GI-2: toleration of solid food and bowel movement) and postoperative LOS. The secondary end points included POI-related morbidity (postoperative nasogastric tube insertion or investigator-assessed POI resulting in prolonged hospital stay or readmission), conversion rate, and protocol-defined prolonged POI (GI-2 > 5 postoperative days). RESULTS: In this study, 148 patients received hemicolectomy by the LC (42 left and 67 right) or HAL (39 left) approach. The conversion rate was 18.8% (25.4% LC left, 17.3% HAL left, 15% LC right). The mean time to GI-2 recovery was 4.4 days, and the mean postoperative LOS was 4.9 days, neither of which varied substantially by surgical approach. Prolonged POI occurred for 15 patients (10.1%), and POI-related morbidity occurred for 17 patients (11.5%). No patients were readmitted because of POI, whereas 3 patients (2%) were readmitted for all other causes. CONCLUSIONS: Mean GI recovery and LOS after LC were accelerated compared with those for patients in open laparotomy bowel resection clinical trials or those reported in large hospital databases (0.7 and 1.7-2.2 days, respectively). Overall POI-related morbidity was similar between the open bowel resection and LC populations, demonstrating that POI continues to present with important morbidity regardless of the surgical approach.

RESUMEN

PURPOSE: The use of laparoscopy surgery in the management of rectal cancer is controversial, especially in the mid and low rectum. The aim of this study was to determine oncologic and long-term outcomes after laparoscopic and hand-assisted laparoscopic surgery for mid and low rectal cancer. METHODS: Between January 1999 and December 2006, 185 patients had surgery for rectal cancer; 103 these patients had mid and low rectal cancer. The source of data was inpatient/outpatient medical records. Telephone interviews were conducted for all patients. Actuarial survival was calculated with use of the Kaplan-Meier method. RESULTS: Hand-assisted laparoscopic surgery was performed in 58 (56.3%) patients, and pure laparoscopic surgery in 45 (43.7%) patients. Mean follow-up time was 42.1 months. The conversion rate was 2.9%. All specimen margins were negative. The anastomotic leak rate was 7.8% (n = 8). There was no 30-day mortality. Local recurrence rate was 5% at five years. Overall survival was 91% and disease-free survival was 73.1% at five years. CONCLUSION: Laparoscopic surgical techniques for mid and low rectal cancer seem safe and feasible with acceptable oncologic and long-term outcomes. Further studies, comparing laparoscopic and open methods, are warranted.

RESUMEN

OBJECTIVE: To determine whether clinical evaluation reporting using the IDEAL (Idea, Development, Exploration, Assessment and Long-term study) framework improves a novel double-balloon endoscopic stabilization technology. DESIGN: Observational registry 6 month study with no follow-up. Using the Prospective Development Study (PDS) format recommended by the IDEAL collaboration, we report on continued refinement and optimization of an endoscopic stabilization platform during a clinical study conducted by two clinicians from the first case onwards. Key outcomes (ability to reach cecum, inflation of balloons in the sigmoid and ascending colon, and complications) were prospectively reported for each patient sequentially. All changes to technique were highlighted, showing when they occurred and an explanation for the change. RESULTS: 30 colonoscopies were undertaken using the device from April to September 2017. Two patients were excluded from the analysis for protocol deviations. Cecum was reached in 89% of the per protocol population of patients in an average time of 13.5 ±â€¯11 min. Therapeutic zone creation was successful in 89% of patients on the right side of the intestine and 100% in those that reached the sigmoid. There were five deliberate changes in technique that occurred during the study that enabled improved device technical performance. There were no serious complications and one polyp was removed successfully using the device. Clinicians reported endoscope stability and increased visibility of the intestinal mucosa increased when using the device. CONCLUSION: The IDEAL framework provided a structured reporting of the changes made to technique. Those changes facilitated a device that is safe, has achieved stability with improved performance.

RESUMEN

PURPOSE: The study investigated the impact of prior abdominal surgery on conversions and outcomes of laparoscopic right colectomy. METHODS: A consecutive series of 414 patients with cancer or adenomas who underwent a laparoscopic right colectomy from March 1996 to November 2006 were studied for surgical conversions and outcomes. Conversion was defined as an incision length > 7 cm. RESULTS: Patients with prior abdominal surgery (n = 191) were compared with patients with no prior abdominal surgery (n = 223), and showed no significant differences in age, ASA classification, length of stay, operative time, blood loss, harvested nodes, tumor size, and specimen length. Significantly more wound infections occurred in the prior abdominal surgery group (22 vs.12, P = 0.023). Body mass index > 30 showed a three-fold increased risk of conversion. Fifteen percent of the no prior abdominal surgery patients and 17 percent of the prior abdominal surgery patients were converted (P > 0.05). Conversion was associated with a longer mean length of stay (8.8 days) relative to laparoscopically completed cases (6.3 days) regardless of prior abdominal surgery history (P < 0.0001). CONCLUSIONS: Laparoscopic right colectomy for neoplasia was not associated with a higher conversion rate or morbidity in patients with prior abdominal surgery. Prior abdominal surgery is not a contraindication to laparoscopic right colectomy.

RESUMEN

PURPOSE: This study was designed to compare short-term outcomes after hand-assisted laparoscopic vs. straight laparoscopic colorectal surgery. METHODS: Eleven surgeons at five centers participated in a prospective, randomized trial of patients undergoing elective laparoscopic sigmoid/left colectomy and total colectomy. The study was powered to detect a 30-minute reduction in operative time between hand-assisted laparoscopic and straight laparoscopic groups. RESULTS: There were 47 hand-assisted patients (33 sigmoid/left colectomy, 14 total colectomy) and 48 straight laparoscopic patients (33 sigmoid/left colectomy, 15 total colectomy). There were no differences in the patient age, sex, body mass index, previous surgery, diagnosis, and procedures performed between the hand-assisted and straight laparoscopic groups. Resident participation in the procedures was similar for all groups. The mean operative time (in minutes) was significantly less in the hand-assisted laparoscopic group for both the sigmoid colectomy (175 +/- 58 vs. 208 +/- 55; P = 0.021) and total colectomy groups (time to colectomy completion, 127 +/- 31 vs. 184 +/- 72; P = 0.015). There were no apparent differences in the time to return of bowel function, tolerance of diet, length of stay, postoperative pain scores, or narcotic usage between the hand-assisted laparoscopic and straight laparoscopic groups. There was one (2 percent) conversion in the hand-assisted laparoscopic group and six (12.5 percent) in the straight laparoscopic group (P = 0.11). Complications were similar in both groups (hand-assisted, 21 percent vs. straight laparoscopic, 19 percent; P = 0.68). CONCLUSIONS: In this prospective, randomized study, hand-assisted laparoscopic colorectal surgery resulted in significantly shorter operative times while maintaining similar clinical outcomes as straight laparoscopic techniques for patients undergoing left-sided colectomy and total abdominal colectomy.

RESUMEN

BACKGROUND: Iatrogenic perforation of the colon during elective colonoscopy is a rare but serious complication. Treatment using laparoscopic methods is a novel approach, only described in the recent literature. We hypothesized that laparoscopic treatment of iatrogenic colon perforation would result in equal therapeutic efficacy, less perioperative morbidity, smaller incisions and decreased length of stay, and an overall better short-term outcome compared to open methods. METHODS: We reviewed our prospectively collected patient database from July 2001 to July 2005 and compared the intraoperative data and postoperative outcomes of patients who underwent laparoscopic primary repair versus those who had open primary repairs of iatrogenically perforated large bowel. RESULTS: The laparoscopic (mean age 70 years; range 20-91 years; 18 percent male) and open (mean age 68 years; range 36-87 years; 43 percent male) groups were similar with regard to age. Overall, patients who underwent laparoscopic (n = 11) versus open (n = 7) repair had comparable operative (OR) times (mean 104 minutes, range 60-150 minutes versus mean 98 minutes, range 40-130 minutes, p = 0.04), shorter length of stay [LOS, (5.1 +/- 1.7 days versus 9.2 +/- 3.1 days, p = 0.01)], fewer complications (two versus five, p = 0.02) and shorter incision length (16 +/- 14.7 mm versus 163 +/- 54.4 mm, p = 0.001). CONCLUSIONS: A laparoscopic approach to iatrogenic colon perforation results in decreased morbidity, decreased length of stay, and a shorter incision length compared to an open method. In those cases where it is feasible and the surgical skills exist, a laparoscopic attempt at colon repair should probably be the initial clinical approach.
