Surg Endosc 2017; 31:3912-3921. [PMID: 28281115 DOI: 10.1007/s00464-017-5422-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2016] [Accepted: 01/20/2017] [Indexed: 12/17/2022]
Abstract
BACKGROUND Recent American College of Surgeons National Surgical Quality Improvement Project (ACS-NSQIP)-based evidence indicates that laparoscopic (LAP) colectomy results in improved outcomes compared to hand-assisted laparoscopic (HAL) colectomy in the general population. Previous comparative studies demonstrated that the HAL technique offers distinct advantages for obese patients. The aim of this study was to perform comparative analyses of HAL and LAP colectomy and low anterior resection (LAR) in obese patients. METHODS The ACS-NSQIP public use file and targeted colectomy dataset, 2012-2014, were utilized for patients undergoing colectomy and LAR. Only obese patients (BMI > 30) and laparoscopic or hand-assisted operations were included. Patient, operation, and outcome variables were compared in two separate cohorts: colectomy and LAR. Bivariate analysis compared the approaches, followed by multivariable regression. RESULTS Of 9610 obese patients included, HAL and LAP colectomy were performed in 3126 and 3793 patients and LAR in 1431 and 1260 patients, respectively. In comparison to LAP colectomy, HAL colectomy patients had increased comorbidities including class 2 and 3 obesity. HAL colectomy was associated with higher overall morbidity (20 vs. 16%, p < 0.001), infectious complications (10.2 vs. 7.7%, p < 0.001), anastomotic leaks (3.0 vs. 2.2%, p = 0.03), and ileus (11 vs. 8%, p < 0.001). Multivariate analysis indicated that overall morbidity (OR 1.27, 95% CI 1.11-1.44), infectious complications (OR 1.35, 95% CI 1.14-1.59), and ileus (OR 1.33, 95% CI 1.12-1.57) were each increased in the HAL colectomy cohort but not different for HAL and LAP LAR. CONCLUSIONS In comparison to LAP colectomy, the HAL technique is used more often in obese patients with an increased operative risk profile. While inherent bias and unmeasured variables limit the analysis, the available data indicate that the HAL technique is associated with increased perioperative morbidity. Alternatively, HAL and LAP LAR are performed in obese patients with a similar risk profile and result in similar postoperative outcomes.

Abstract
AIM Laparoscopic rectal cancer surgery has been increasingly used since 1991 following the publication of the first case series. Since then, several studies have confirmed that laparoscopic surgery for rectal cancer is challenging with associated morbidity and mortality. The aim of this study was to determine if the rates of early postoperative complications in laparoscopic rectal cancer surgery have improved over the past 20 years. METHOD A literature search of the EMBASE and MEDLINE databases between August 1991 and August 2011 was conducted using the keywords laparoscopy, rectal cancer and postoperative complications. Data were analysed using linear regression ANOVA performed in GNUMERICS software. RESULTS Ninety-seven studies were included for analysis. Over the last 20 years there has been no significant change in the rate of any early postoperative complications (anastomotic leak, conversion, sexual, urinary or faecal dysfunction, wound infection, overall morbidity or mortality). However, in the last 3 years, the rate of positive resection margins has decreased significantly (P = 0.01). CONCLUSION There was no evidence of a statistically significant change in early postoperative complications until 3 years ago. This may reflect the inherent morbidity associated with rectal surgery regardless of the approach used, the limitations of the current laparoscopic instrumentation or the relatively long learning curve. With increasing experience, a repeat analysis in the near future following the publication of ongoing randomized clinical trials might show improved outcomes.

Abstract
INTRODUCTION Laparoscopic approaches are increasingly being used in patients with colorectal cancer, but the feasibility of laparoscopic resection of synchronous colorectal cancers in separate specimens remains unknown. In such cases, it is necessary to consider the site of port placement, sequence of dissection, choice of specimen extraction sites, specimen handling, and extracorporeal anastomosis sites. Moreover, the need for complete mesenteric dissection in two areas, removal of two separate specimens containing malignancies, and two anastomoses elicit unique questions related to technical considerations. The aim of this study was to determine the feasibility of laparoscopic resection of two separate specimens containing malignancies for multiple synchronous colorectal cancers. METHODS Between June 2001 and January 2013, 1341 patients with colorectal cancer underwent laparoscopic surgery at our institution. Of them, 11 patients underwent laparoscopy-assisted combined resection of two separate colorectal specimens for multiple synchronous primary colorectal cancers. We retrospectively reviewed their surgical outcomes. RESULTS All procedures were completed laparoscopically without perioperative mortality. Patients underwent right-sided colon resection for right-sided cancer and left-sided or rectal resection for left-sided colon or rectal cancer. The median duration of surgery was 296 min, and the median blood loss was 65 mL. Median time to first postoperative liquid and solid intake was 1 day and 3 days, respectively. Most patients were discharged on postoperative day 8. With regard to postoperative complications, two patients had a surgical-site infection. CONCLUSION Laparoscopic resection of two separate colorectal specimens for multiple synchronous primary colorectal cancers is a feasible and safe procedure.

Abstract
PURPOSE This study evaluated the risk factors for anastomotic leakage after laparoscopic surgery for rectal cancer using a stapling technique. METHODS The total prospective registry of 111 patients with rectal cancer who initially underwent laparoscopic low anterior resection using a stapling technique was reviewed. Univariate and multivariate analyses were carried out to identify relevant risk factors. RESULTS Overall anastomotic leakage rate was 5.4% (6/111). Univariate analysis demonstrated that body mass index (BMI) (P=0.0377) was significantly associated with anastomotic leakage. After univariate analysis, the variables of BMI and the size of the circular stapler (P=0.0923) were selected for multivariate analysis, as their P values were <0.2, and multivariate analysis demonstrated that BMI was independently predictive of developing anastomotic leakage (P=0.0458). CONCLUSIONS Laparoscopic surgery for rectal cancer using a stapling technique can be performed safely without increasing the risk of anastomotic leakage, and increased BMI might be a potential risk factor for anastomotic leakage.

Abstract
The first-line treatment for intra-abdominal abscess is source control. Sometimes, however, source control is too invasive for relatively small abscesses and is not feasible due to the risk of injury to some organs. Based on reports that fosfomycin (FOM) can break up biofilms to enhance the permeability of other antibiotics, we investigated the FOM time-lag combination therapy (FOM-TLCT). We enrolled 114 patients who had intra-abdominal abscess after gastrointestinal surgery and examined the efficacy of FOM-TLCT using the same therapeutic antibiotic (TA) as that which had been used previously, but had proven ineffective, at the same dose schedule. The efficacy endpoint determination was carried out as follows: among the systemic inflammatory response syndrome (SIRS)-positive cases, even after administration of TA, excellent outcome was defined as SIRS negative within 7 days of FOM-TLCT with TA without the need for other treatment, including other antibiotics or drainage. Of the 114 patients enrolled, 104 cases (SIRS positive 73; SIRS negative 31) were assessed. Ten patients were excluded; four had received TA at higher doses, three had received different TAs, and three were considered to have bacteria resistant to TAs. Among these patients, 86.3% (63/73) of the SIRS-positive cases were classified as excellent, and 90.3% (28/31) of the SIRS-negative cases were classified as effective. In total, the efficacy rate was 87.5% (91/104). The total no-response rates were 12.5% (13/104). FOM-TLCT seems to be effective for treating refractory intra-abdominal abscess.

Intraoperative technical difficulty during laparoscopy-assisted surgery as a prognostic factor for colorectal cancer. Dis Colon Rectum 2010; 53:1400-8.

Abstract
BACKGROUND Laparoscopy-assisted surgery has technical drawbacks compared with open surgery, although laparoscopic surgery has become widely adopted with evidence of oncological safety for colon cancer treatment. The oncological risk of technical difficulties during laparoscopic surgery for colorectal cancer has not been previously reported. We aimed to investigate whether a technical difficulty encountered during laparoscopic surgery can be considered a recurrence-related factor for colorectal cancer. METHODS Data from 427 patients who underwent laparoscopic surgery for colorectal cancer between May 2003 and December 2007 were analyzed. An intraoperative technical difficulty was defined as a significant deviation from the ordinary surgical procedure. All conversions to open surgery and iatrogenic bowel perforation during laparoscopic surgery were included as technical difficulties. The Cox proportional-hazards regression model was used to evaluate the recurrence-related factor in the various risk factors including technical difficulty. RESULTS Technical difficulties were found in 44 (10.3%) patients, which included 17 (3.9%) conversions to open surgery and 10 (2.4%) with iatrogenic bowel injury. Technical difficulties were encountered more frequently in men compared with women (13.5% vs 6.0%, P = .013), and for cancers located in the mid and low rectum, splenic flexure, and descending colon. The recurrence rates were higher in patients with technical difficulties (local recurrence, 2.6% vs 6.7%, P < .05; systemic recurrence, 6.3% vs 13.6%, P < .05) with a mean follow-up duration of 45.9 months. Multivariate analysis by the Cox proportional-hazards regression model showed that a technical difficulty was an independent factor related to recurrence after laparoscopic surgery (odds ratio, 2.374; 95% CI, 1.006-5.600; P = .048). CONCLUSIONS This study has demonstrated that a technical difficulty during laparoscopy-assisted surgery jeopardizes oncological safety. It is suggested that surgeons should be prepared to minimize technical difficulties during laparoscopy-assisted surgery.

Abstract
BACKGROUND In laparoscopic operations for rectal carcinoma, only a few multicenter studies of a large number of patients have examined the impact of conversion on outcomes and determined risk factors for conversion. This study was designed to evaluate short-term outcomes and risk factors for conversion to open operation in laparoscopic operations for rectal carcinoma. STUDY DESIGN A total of 1,073 patients with carcinoma of the rectum and anus who underwent laparoscopic operations were reviewed retrospectively. Patients were collected from 28 institutions. Patients who required conversion during laparoscopic operation were compared with those with completed laparoscopic resection. RESULTS Conversion rate was 7.3% (n = 78), and patients requiring conversion were considerably heavier (mean body mass index 24.6 versus 22.7) and had a substantially higher rate of low anterior resection (94.9% versus 83.5%). Conversion was also associated with longer operation time (median 295 minutes versus 270 minutes), greater blood loss (median 265 mL versus 80 mL), longer median postoperative hospital stay (20 days versus 14 days), and higher rates of intraoperative (32.1% versus 3.5%) and postoperative (43.6% versus 21.1%) complications. In multivariate analysis, body mass index and rate of low anterior resection were predictive of conversion. CONCLUSIONS Conversion to open operation is associated with greater morbidity than completed laparoscopic resection. Body mass index and the particular laparoscopic procedure are risk factors for conversion, indicating that appropriate patient selection is essential in laparoscopic operations for rectal carcinoma.

Abstract
BACKGROUND This study evaluated the role of the acute phase C-reactive protein (CRP) in the postoperative course of a large series of rectal resections on the basis of a prospective database. Main focus of this study was the early identification of complications. MATERIALS AND METHODS Three hundred eighty-three rectal resections with primary anastomosis for rectal cancer were screened for infectious postoperative complications. Forty-eight complicated cases were identified and matched with 48 patients with an uneventful postoperative course. RESULTS In the postoperative setting, CRP peaked on postoperative day (POD) 2 with a median serum CRP of 140 mg/l and gradually declined thereafter in uncomplicated cases. In complicated cases, CRP elevation generally persisted after POD 2, whereas white blood cells and body temperature were within normal range in the early postoperative period. A cutoff CRP value of 140 mg/dl on PODs 3 and 4 resulted in predictive values of 85.7 and 90.5% (adjusted to the prevalence: 37.6 and 50.3%), sensitivities of 80.0 and 54.3%, and specificities of 81.0 and 92.3% for a complicated postoperative course (P<0.001), respectively. CONCLUSION Persistent CRP elevation and elevation of serum CRP above 140 mg/dl on PODs 3-4 are predictive of infectious postoperative complications and should prompt intense clinical search for an inflammatory process, especially for an anastomotic leak if pneumonia and wound infection are unlikely or excluded.

Abstract
BACKGROUND The aim of this study was to evaluate various clinical parameters that would influence the occurrence of wound infection (WI) in elective laparoscopic surgery (LS) for colorectal carcinoma. METHODS The study included 290 patients who underwent LS between June 2001 and December 2005. WI was diagnosed within 30 days of the operation, and both superficial and deep incision surgical site infection were evaluated together. RESULTS Eighteen (6.2%) were diagnosed with WI. Of the infected patients, nine (50%) had WI at the extraction site, six (33%) at the port site of the drainage tube, and three (17%) at the supraumbilical incision. Following bivariate analysis, the variables of stoma creation, intraoperative hypotension, and length of operation were selected for multivariate analysis as their P values were <0.2, the predominant cutoff, and stoma creation and intraoperative hypotension were independently predictive of developing WI. Regarding the duration of postoperative hospital stay, there was no significant difference between patients with or without WI. CONCLUSIONS Stoma creation and intraoperative hypotension were independent risk factors for WI. The results obtained in this study should be considered in an effort to prevent WI in LS for colorectal carcinoma, although these risk factors need further evaluation.

Abstract
BACKGROUND In evaluating the quality of laparoscopic surgery (LS) for colorectal carcinoma, many previous reports have used median or range values to assess the length of postoperative hospital stay and to show the complication and conversion rates separately. However, with this method, it is impossible to assess the proportion of patients who required prolonged postoperative hospital stay because of perioperative morbidities. This study investigated the proportion of patients who benefited from LS as minimally invasive surgery by assessing the percentage of patients who required prolonged postoperative hospital stay because of major perioperative morbidities. METHODS A review of 202 patients who underwent LS for colorectal carcinoma at the authors' hospital between January 2002 and December 2004 was performed. Short-term outcomes were compared among the patients who underwent LS in 2002, 2003, and 2004. RESULTS No significant differences were observed in baseline characteristics among the groups, and all the procedures in this study were completed laparoscopically. There were no significant differences in the operative times and intraoperative blood losses among the groups. Most of the patients resumed liquid intake on postoperative day 1 and solid food on day 3. However, there was a significant difference in the rate of postoperative prolonged hospital stays by year of surgery. In 2004, 97.3% of the patients (72/74) undergoing LS could be discharged to home within 8 days postoperatively. Major complications occurred at a low rate of 1.4% (1/74) in 2004. Regarding the reasons for prolonged postoperative hospital stay, inappropriate judgment of the physician in charge, based primarily on requests from patients without medical necessity, disappeared in 2004. CONCLUSIONS When LS is performed properly by specialists who have accumulated sufficient experience in both LS and conventional open surgery for colorectal carcinoma, up to 97% of patients undergoing LS can benefit from minimally invasive surgery.

Abstract
BACKGROUND Division of the rectum following total mesorectal excision (TME) using intracorporeal stapling devices is technically difficult due to their width and limited roticulation. More than one cartridge is often required and resultant wedging of the stump may be associated with an appreciable leak rate. METHODS Three-dimensional reconstruction was performed of CT and MRI images from the lower abdomen of six patients undergoing laparoscopic TME using the Amira software environment. The stapling device was virtually reconstructed by in-house developed software, superimposed over the point of division of the rectum and the site of skin entry identified. RESULTS The 45 degrees angulation of available roticulating stapling devices precludes perpendicular division of the rectum following laparoscopic TME. The optimal angulation for transverse rectal stapling varied between 62 degrees and 68 degrees . CONCLUSION A roticulating stapler with minimum angulation of 65 degrees would achieve transverse division of the rectum following laparoscopic TME.
