Bowel, bladder and sexual function in women undergoing laparoscopic posterior compartment repair in the presence of apical or anterior compartment dysfunction.
OBJECTIVE: The aim of the study was to analyse the functional outcome of women undergoing a laparoscopic posterior compartment repair in the presence of anterior or apical compartment dysfunction. DESIGN: Prospective cohort study. METHODS: Forty women, median age 65 years (41-78), with symptoms of genital prolapse 31 (78%), urinary dysfunction 32 (80%) and bowel dysfunction 40 (100%), underwent laparoscopic posterior compartment repair in conjunction with an anterior compartment repair. Pre-operative and postoperative bowel and bladder function was prospectively assessed with a Wexner continence score, Vienna constipation score and a urinary dysfunction score. Twenty-eight (70%) and 24 patients (60%) had pre-operative urodynamics and anorectal manometry. Post-operatively all women were also assessed with a Watt's sexual dysfunction score and a linear analogue patient satisfaction score. Twelve women (30%) had postoperative anal manometry. RESULTS: At 20 months median follow-up, 30 (97%), 20 (62%) and 12 (31%) women reported improvement in their prolapse, urinary and bowel symptoms, respectively. Post-operatively, one woman reported denovo faecal incontinence, four worsening obstructive defecation and three denovo urinary dysfunction. Nine women (35%) reported denovo dyspareunia. The mean time to clinical deterioration following surgery was 11 months. Bowel function improvement was the only factor to significantly correlate with postoperative patient satisfaction. CONCLUSION: The functional outcome of laparoscopic posterior compartment repair in the presence of anterior compartment dysfunction is disappointing. Preoperative counselling is important to ensure that patients have reasonable and realistic expectations from repair surgery, and an understanding that anatomical improvement might not be followed by long-term functional improvement.

Abnormal predefecatory colonic motor patterns define constipation in obstructed defecation.
BACKGROUND & AIMS: The pathophysiology of constipation in the syndrome of obstructed defecation is unknown. Using 24-hour pancolonic manometric recordings of the unprepared colon to record basal pressures and spontaneous defecation episodes, we tested the hypothesis that the frequency, timing, or spatial distribution of propagating colonic pressure waves is abnormal in patients with obstructed defecation. METHODS: In 11 patients with obstructed defecation and 16 healthy controls, pressures were recorded using a nasocolonic catheter that was positioned such that 16 recording sites spanned the unprepared colon at 7.5-cm intervals. RESULTS: The overall frequency of propagating sequences (PS) in the colon did not differ between patients and controls. When compared with controls, patients had a significant increase in the frequency of retrograde and antegrade PS (P < 0.05) in the left colon and a significant reduction in the amplitude of propagating pressure waves throughout the entire colon (P < 0.03). Defecation occurred in 6 of 11 patients and 9 of 16 controls. In the 15 minutes before defecation, controls showed a highly significant increase in frequency (P = 0.001) and amplitude (P = 0.01) of PS. In contrast, patients did not demonstrate this or the typical spatiotemporal organization of PS normally observed before expulsion of stool. CONCLUSIONS: Patients with obstructed defecation lack the normal predefecatory augmentation in frequency and amplitude of propagating pressure waves and lack the normal stereotypic spatiotemporal patterning of colonic pressure waves that would normally culminate in effective expulsion of stool.

Use of endoscopic titanium stapler in rectal anastomotic stricture.
A quick and effective technique is described here for the treatment of rectal anastomotic stricture. It consisted of cutting the stricture using the Ethicon 35-mm Endoscopic Titanium Stapler. A patient was treated here as a day-surgery case. Good functional and anatomic results were achieved on follow-up.
