The impact of mesenteric tension on pouch outcome and quality of life in patients undergoing restorative proctocolectomy.

AIM: The study aimed to establish a method for the measurement of mesenteric tension after ileal pouch-anal anastomosis (IPAA) and to evaluate the impact of tension on clinical outcome and quality of life. METHODS: All consecutive patients undergoing an open IPAA from July 2008 to October 2009 were prospectively enrolled. After the creation of the anastomosis, mesenteric tension was estimated by the surgeon in the operating room on a 10-point scale (1, least tension; 10, most tension). The association was analysed between mesenteric tension defined as low (1-2), medium (3-7) and high (8-10) and postoperative complications and quality of life (Cleveland Clinic Global Scale). RESULTS: A mesenteric tension score was obtained in 134 patients (71 men, 53.0%). Median age was 38.5 (29.3-47.0) years. Fifty-six patients (41.8%) had a low, 59 (44.0%) a medium and 19 (14.2%) a high degree of mesenteric tension. Patients with a high mesenteric tension had a shorter anal transitional zone, a longer distance from the upper border of the symphysis pubis to the apex of the small bowel loop designated for the ileoanal anastomosis, a thinner abdominal wall at the stoma site and a longer distance from the pouch to the ileostomy. The proportion of patients with high mesenteric tension was less after stapled anastomosis. On long-term follow-up, patients with high mesenteric tension were more likely to suffer from anastomotic stricture and pouch failure. Pouch function was not influenced by mesenteric tension. CONCLUSION: High mesenteric tension after IPAA is adversely associated with postoperative complications and pouch survival.

The negative effects of surgery persist beyond the early postoperative period after laparoscopic colorectal resection.

PURPOSE: The recovery benefits of laparoscopy are traditionally believed to minimize the initial negative impact of surgery on early postoperative quality of life (QOL). We evaluate whether laparoscopic colectomy leads to recovery of QOL early after surgery and evaluate factors associated with the change in QOL. METHODS: Preoperative and early postoperative QOL data (SF-36) were prospectively accrued for patients undergoing laparoscopic colorectal resection (LCR) (2002-2009). Changes in postoperative QOL from preoperative values and effects of patient, disease, operation and postoperative outcomes on these changes were evaluated. RESULTS: One hundred and sixty-six patients (female = 86) underwent LCR for cancer (n = 79), Crohn's disease (n = 24), diverticulitis (n = 38), and ulcerative colitis (n = 25) with complete SF-36 scores. Median age was 56.9 (range: 15-91) years, mean body mass index 27.4 ± 6.2 kg/m(2) with American Society of Anesthesiologists (ASA) class being II in 94 patients. Median operative time was 152.5 (range: 50-358) min; mean length of stay (LOS) 4.5 ± 3.3 days. At 4 weeks, the postoperative SF-36 physical component scale (PCS) continued to be lower than the preoperative PCS (41.8 ± 8.8 vs. 47.1 ± 9.4, P < 0.001), while the postoperative SF-36 mental component scale (MCS) was similar to the preoperative MCS (45.6 ± 10.2 vs. 46.1 ± 11.9, P = 0.17). Gender, age, operation, LOS, surgeon, ASA, BMI, complications, and readmission were not associated with a change in QOL from preoperative values. Cancer as an indication for surgery was associated with less improvement of MCS and PCS (P = 0.024 and 0.004, respectively). CONCLUSIONS: Although patients who undergo LCR may have clinical evidence of healing at 4 weeks after surgery, QOL does not return to the preoperative level. This finding may help develop evidence-based recommendations pertaining to timing of return to full activity.

Laparoscopic single-port colectomy for sigmoid cancer.

BACKGROUND: Single-port laparoscopic surgery can be performed via one incision hidden in the umbilicus. Herein, we report a patient with a sigmoid colon cancer undergoing single-port laparoscopic sigmoid colectomy. METHODS: Laparoscopic single-port sigmoid colectomy through a 3-cm umbilical incision was performed on a patient with a diagnosis of sigmoid cancer. Patient was 54-year-old female with a body mass index of 25.8 kg/m(2). Preoperatively, a CAT scan in the metastasis evaluation did not show any lesion. RESULTS: The total operative time was 198 min. Estimated blood loss was 300 ml. Length of hospital stay was 3 days. Patient had no intraoperative or postoperative complications. Examination of pathological specimen showed a specimen containing a circumferential lesion measuring 5 cm x 2.5 cm x 2.5 cm with adequate surgical margins (10 and 5.5 cm), and no regional lymph node metastases in 14 lymph nodes collected. Patient did not receive adjuvant chemotherapy after surgery. Colonoscopy performed 1 year after surgery showed no neoplasm or polyp identified. Abdomen and pelvis CT also found no evidence of recurrence or metastatic disease. CONCLUSION: Single-port laparoscopic surgery may allow common benign procedures via an incision in the umbilicus. It can also be performed with good surgical and oncologic results in selected patients with a colorectal cancer.

Outcomes following Turnbull-Cutait abdominoperineal pull-through compared with coloanal anastomosis.

BACKGROUND: The Turnbull-Cutait abdominoperineal pull-through procedure (T-C) is used as a last resort to avoid permanent diversion in patients with complex anorectal conditions. The aim was to evaluate short- and long-term outcomes after T-C. METHODS: Patients undergoing T-C from 1996 to 2007 were reviewed retrospectively in terms of demographics, diagnosis, indications and postoperative complications. Patients were contacted to obtain functional outcomes using a standardized questionnaire. Functional outcomes were compared with those in a matched group of patients undergoing handsewn coloanal anastomosis (CAA) for rectal cancer. RESULTS: Sixty-seven patients (40 men) underwent T-C. Postoperative complications included stricture in 11 patients (16 per cent), fistula in five (7 per cent), prolapse of the colon in five (7 per cent) and leak in two (3 per cent). Mean follow-up was 5.6 (s.d. 3.2) years. The operation failed in 17 patients (25 per cent). Among 44 patients (66 per cent) who completed questionnaires, faecal (P = 0.121) and urinary (P = 0.073) incontinence, and sexual function (P = 0.063) were comparable to those in patients who had CAA. CONCLUSION: T-C is an option for patients with complex anorectal conditions that might otherwise require permanent diversion. Functional outcomes are comparable to those of CAA.

Single-port laparoscopy in colorectal surgery.

PURPOSE: Laparoscopy is the approach of choice for the majority of colorectal disorders that require a minimally invasive abdominal operation. As the emphasis on minimizing the technique continues, natural orifice surgery is quickly evolving. The authors utilized an embryologic natural orifice, the umbilicus, as sole access to the abdomen to perform a colorectal procedure. Herein, we present our initial experience of single-port laparoscopic colorectal surgery using a Uni-X Single-Port Access Laparoscopic System (Pnavel Systems, Morganville, New Jersey, USA) with a multi-channel cannula and specially designed curved laparoscopic instrumentation. METHOD: The abdomen was approached through a 3.5 cm incision via the umbilicus and a single-port access device was utilized to perform a right hemicolectomy on a patient with an unresectable caecal polyp and a body mass index of 35. Ligation of the ileocolic artery was done with a LigaSure Device (Covidien Ltd, Norwalk, Connecticut, USA), and was followed by colonic mobilization, extraction and extracorporeal ileocolic anastomosis. RESULTS: The total operative time was 115 min with minimal blood loss. Hospital stay was 4 days with no undue sequelae. CONCLUSION: Single-port laparoscopic surgery may allow common colorectal laparoscopic operations to be performed entirely through the patient's umbilicus and enable an essentially scarless procedure. Additional experience and continued investigation are warranted.
