Outcomes after operations for anal fistula: results of a prospective, multicenter, regional study.

BACKGROUND: There are various surgical techniques used treat anal fistulas. The adoption and success rates of newer techniques have not been clearly established. OBJECTIVE: The purpose of this study was to determine the healing rate after operations for anal fistulas in New England colorectal surgery practices. DESIGN: We conducted a retrospective review of a prospectively collected database. SETTINGS: The study was conducted at colorectal surgery practices in New England. PATIENTS: A prospective, multicenter registry was created by the New England Society of Colon and Rectal Surgeons. Surgeons were invited to collect data prospectively regarding patients operated on for anal fistulas between January 1, 2011, and August 1, 2013. Fistula classification, surgical intervention, continence scores, and healing were determined by the treating surgeon. INTERVENTION: Operation for anal fistula was performed. MAIN OUTCOME MEASURES: We measured the proportion of patients with healed fistulas at 3 months. RESULTS: Sixteen surgeons submitted data regarding 240 operations for fistula with curative intent. Mean patient age was 45 ± 14 years. A total of 158 patients (66%) were men, and 110 (46%) had undergone an anorectal operation. Twenty-nine (12%) had Crohn's disease. The healing rates of fistulotomy, advancement flap, and fistula plugs at 3 months were 94% (95% CI, 89-97), 60% (95% CI, 33-77), and 20% (95% CI, 5-50). The healing rate of the ligation of intersphincteric fistula tract procedure at 3 months was 79% (95% CI, 65-88). Hospital site was the only variable associated with healing (p < 0.05). Hospitals that performed more ligation of intersphincteric fistula tract procedures had higher healing rates at 3 months (p < 0.0001). LIMITATIONS: This study was limited by selection bias and reporting bias. CONCLUSIONS: A wide variety of techniques are used to treat anal fistulas in our region. Fistulotomy continues to have excellent results. There has been enthusiastic early adoption of the ligation of intersphincteric fistula tract technique. Early healing rates after the ligation of intersphincteric fistula tract procedure appear to be excellent.

Evolution of technique in performance of minimally invasive colectomies.

BACKGROUND: Hand-assisted laparoscopic surgery is commonly used in colorectal surgery and provides benefit in complex cases. OBJECTIVE: This study examined the minimally invasive surgical trends, patient characteristics, and operative variables unique to patients undergoing hand-assisted laparoscopic surgery. DESIGN: This was a retrospective medical chart review. SETTINGS: The study was conducted in a tertiary care medical center. PATIENTS: Patients included in the study were those who underwent pure laparoscopic colectomies, hand-assisted laparoscopic colectomies, and traditional open surgery for elective treatment of diverticular disease, colorectal cancer, IBD, and benign polyp disease. MAIN OUTCOME MEASURES: Primary outcomes included patient characteristics and operative variables unique to patients undergoing hand-assisted laparoscopic surgery and documentation of operative technique trends within an experienced colorectal group. RESULTS: Diverticular disease characteristics specific to hand-assisted laparoscopic surgery included the presence of dense inflammatory adhesions (p < 0.0001), diverticular fistulas (p < 0.0001), and unresolved phlegmon (p = 0.0003). Characteristics specific for colorectal cancer included intraoperative tumor bulk (p < 0.0001) and the inability to achieve appropriate surgical resection margins (p < 0.001). Similarly, variables identified for benign polyp disease included adhesions (p < 0.0001) and the ability to gain adequate exposure (p < 0.0001). Limited use of hand-assisted laparoscopic surgery was observed in patients with IBD. LIMITATIONS: This was a retrospective, observational study from a single center. CONCLUSIONS: Conversion to hand-assisted laparoscopic surgery provides benefit in surgical scenarios where dense inflammatory adhesions, diverticular fistulas, and intra-abdominal postdiverticulitis phlegmon are present. In addition, benefit is observed in patients with colorectal cancer where laparoscopic dissection of bulky tumor proves to be difficult and where the technical ability to obtain margins using pure laparoscopy is compromised. Although our practice has changed to favor pure laparoscopy, hand-assisted laparoscopic surgery continues to play an important role in complex colorectal cases that otherwise would require open surgery (see video, Supplemental Digital Content 1, http://links.lww.com/DCR/A146).

24 hours on-call and acute fatigue no longer worsen resident mood under the 80-hour work week regulations.

PURPOSE: Studies in on-call residents have shown that mood is worsened by fatigue as indicated by increased scores on measures of depression, anxiety, confusion, and anger using the Profile of Mood States (POMS). In prior sleep deprivation studies, mood has been shown to be more affected than either cognitive or motor performances. The purpose of this study was to examine the effect of the 80-hour work week regulations on resident mood in general and in a post-call period (PC). METHODS: Institutional Review Board approval was obtained to survey the residents and publish the results. POMS is a 65-item adjective questionnaire that includes subscales for measuring tension-anxiety, anger-hostility, depression-dejection, vigor-activity, fatigue-inertia, and confusion-bewilderment, with the summation of the scales forming a total mood disturbance score. Surgical residents were tested at a 9 am didactic curriculum session (9 am has been shown to correlate with the nadir of performance). Residents were tested after nights off call (NOC) or after PC. Time asleep in the preceding 24 hours and other demographic data were also collected. Acute fatigue (AF) was defined as <4 hours sleep. The two-sample t-test and linear regression were used to assess differences between groups. RESULTS: A total of 123 standardized POMS mood questionnaires were administered on 4 occasions to 51 surgical residents, 35 men and 16 women at levels PGY-1 through PGY-5. Overall, 33 tests (27%) were taken after PC and 90 (73%) were taken after NOC. Acute fatigue residents had a mean sleep time of 2.2 (+/-1.5) hours, whereas rested (R) residents had a mean sleep time of 6.7 (+/-2.2) hours (whether PC or NOC). No statistical differences in mean values of vigor, anger, depression, concentration, fatigue, tension, or total score were observed between PC and NOC or between AF and R residents. There was no significant relationship between acute sleep deprivation and total mood disturbance, whether PC or NOC. In linear relationships, NOC total score and hours slept had r2 = 0.01 (p = 0.44), whereas PC total score and hours slept had r2 = 0.07 (p = 0.14). CONCLUSION: Although POMS was given 4 times, only 27% were PC, which reflects our 1 in 4 night in-house coverage. In contrast to earlier studies, resident mood, as measured by POMS, is no longer related to PC/NOC or acute fatigue. Previous studies have shown that loss of sleep was associated with declining mood. The lack of such a relationship in this study may be related to the new regulations. It has been assumed that people can adapt to chronic sleep loss but have a harder time coping with the effects of acute sleep deprivation. If, however, the new regulations have relieved chronic sleep deprivation, then a well-rested resident can periodically cope with the effects of acute sleep deprivation. Perhaps by eliminating chronic sleep debt, work hour restrictions seem to have removed the negative impact of PC seen in the prior era. Further studies should increase the number of residents studied, have numerous repeat NOC and PC pairs in same subjects, compare different services with different workloads, junior and senior residents, and in-house and at-home call schedules.

Palliative approaches to the patient with breast cancer.

Despite an increasing trend towards early diagnosis of breast cancer,patients still present with locally advanced disease. Also, in some patients chemotherapy will fail, and local and regional recurrence will occur. This article outlines options for palliative care for such patients.

Colovesical fistula: not a contraindication to elective laparoscopic colectomy.

PURPOSE: Traditionally, diverticular fistula was thought to be a contraindication for laparoscopic colectomy. The advent of hand-assisted laparoscopy has allowed repair of a diverticular fistula to be technically feasible laparoscopically. We present our experience with laparoscopic colectomy in patients with diverticular fistulas. METHODS: Patients with colovesical or colovaginal fistulas secondary to diverticular disease were consecutively entered into a database over a five-year period. All operations were electively performed by a single group of colorectal surgeons. Patient demographics, American Society of Anesthesiologists classification, type of surgery, operating time, hospital length of stay, and early and late complications were recovered by chart review. These results were then compared to results from a group of patients who had undergone elective laparoscopic colectomy for recurrent diverticulitis during the same period by the same group of surgeons. RESULTS: Altogether, 40 consecutive operations for diverticular fistulas were performed, 36 of which were started laparoscopically (90 percent). The average patient age was 65 years and the average American Society of Anesthesiologists class was 2. Patient demographics were similar among the group with recurrent diverticulitis (n = 149). The average hospital stay was 6.2 days for the fistula group and 4.4 days in the recurrent diverticulitis group. The average operating time was 220 minutes for the fistula group vs. 176 minutes for the uncomplicated group (P < 0.002). The conversion rate was significantly higher in the fistula group (25 percent vs. 5 percent, P < 0.001). There were no postoperative anastomotic leaks or bleeding episodes requiring reoperation in the fistula group. CONCLUSIONS: Diverticular fistula should no longer be considered a contraindication for laparoscopic colectomy. These cases are more complex, as evidenced by the longer operating times and higher conversion rates when compared with resections for uncomplicated recurrent diverticulitis. Although the length of hospital stay was longer for patients who underwent laparoscopic colectomy for diverticular fistula, those whose operations were completed laparoscopically had the same outcome as patients with uncomplicated disease. We anticipate that minimally invasive surgery will become the standard of care for colovesical fistula, as it now is for uncomplicated diverticular disease.
