Kock pouch

BACKGROUND: The ileal pouch-anal anastomosis has been successful in restoring intestinal continuity and preserving continence in the majority of patients requiring a proctocolectomy. However, a subset of individuals experience significant complications that might result in pouch failure. The conversion of the J pouch to a continent ileostomy pouch represents a significant surgical procedure. In this article, we discuss the indications and contraindications, present the technical principles applied for the conversion, and describe the outcomes of such conversion in the literature...

BACKGROUND: Kock's continent ileostomy is an option after proctocolectomy for patients not suitable for ileal pouch anal anastomosis or ileorectal anastomosis. Ulcerative colitis is the most common indication for continent ileostomy. OBJECTIVE: The aim of this study was to evaluate the long-term outcome of continent ileostomy. DESIGN: Retrospective cohort register study. SETTINGS: Data were obtained from the Swedish National Patient Registry...

The continent ileostomy (CI) was popularized by Nils Kock as a means to provide fecal continence to patients, most commonly in those with ulcerative colitis, after proctocolectomy. Although the ileal pouch-anal anastomosis (IPAA) now represents the most common method to restore continence after total proctocolectomy, CI remains a suitable option for highly selected patients who are not candidates for IPAA or have uncorrectable IPAA dysfunction but still desire fecal continence. The CI has exhibited a fascinating and marked evolution over the past several decades, from the advent of the nipple-valve to a distinct pouch design, giving the so-inclined and so-trained colorectal surgeon a technique that provides the unique patient with another option to restore continence...

Continent ileostomies are performed in patients who are not candidates for or do not want a traditional J-pouch after total colectomy. In these cases, patients may opt for a type of continent ileostomy instead of an end ileostomy. The most common types of continent ileostomies include the Kock (K) pouch, S-pouch and Barnett Continent Intestinal Reservoir. The normal fluoroscopic and CT appearance of these types of continent ileostomies are reviewed. CT provides better evaluation of the proximal small bowel and pouch for inflammatory bowel disease, while fluoroscopy is superior in evaluating the nipple valve...

PURPOSE: To investigate the long-term satisfaction and complications in chronic spinal cord injury (SCI) patients after various bladder management strategies and surgical procedures for the treatment of urinary incontinence. METHODS: Patients at a single institution with chronic SCI who received bladder management treatment or surgical procedure to improve urinary continence were retrospectively assessed. Thorough urological examinations and videourodynamic studies were performed...

BACKGROUND: Continent ileostomy was first introduced by Nils Kock in 1969 as Kock pouch (K-pouch). Its most characteristic feature, the nipple valve that offers continence' was a later addition. Even though today's continent ileostomy is sidelined by ileal pouch-anal anastomosis as the gold standard of restorative procedures for colectomy patients, it remains an excellent option for select patients, offering an alternative to end-ileostomy or a poorly functioning ileoanal pouch. OBJECTIVE: The study aimed to summarize principles and techniques behind K-pouch construction, both de novo and as "J to K" conversion, as well as examine surgical outcomes following the procedure in the modern era regardless of indication...

In patients with familial adenomatous polyposis (FAP), adenomas and even carcinomas may develop in the rectal remnant and the ileal pouch after surgical treatment. The aim of this study was to evaluate the outcome of endoscopic management in patients with FAP. The main outcome measurements were the appearance of secondary cancer, complications, and the need for additional surgery. Thirty-four FAP patients with Kock's continent ileostomy (Kock) ( n = 3), ileorectal anastomosis (IRA) ( n = 12), and ileal pouch-anal anastomosis (IPAA) ( n = 19) were identified...

PURPOSE: The aim of the study was to investigate the underlying cause of long-term complications in patients requiring at least one revision surgery of a continent ileostomy (CI) and to analyze functional outcome. METHODS: Only patients with CI at least one revision were included in the retrospective data analysis. Four different classes of complications (Cl A-D) were defined: Cl A = Nipple valve (NV), Cl B = pouch, Cl C = outlet (stoma), and Cl D = afferent loop (AL)...

AIM: The continent ileostomy allows evacuation of an ileal reservoir at a time convenient to the patient. It is a surgical option for patients with ulcerative colitis (UC) when a restorative option is not suitable or has not succeeded and the patient does not want a conventional end ileostomy. Continent ileostomy types include the Kock pouch, Barnett continent intestinal reservoir and T-pouch. All of the published evidence on the long-term outcome and quality of life after continent ileostomy for UC was systematically reviewed...

OBJECTIVE: To characterize afferent nipple valve obstruction in Kock diversions presenting with hydronephrosis and discuss appropriate work-up and management. METHODS: We retrospectively reviewed 7 cases of afferent nipple valve obstruction. RESULTS: The median time from diversion creation to afferent nipple valve intervention was 17-years. Presentations included febrile-UTIs, worsening renal function and hydronephrosis. All patients underwent upper tract imaging confirming bilateral hydronephrosis or hydronephrosis of a solitary kidney followed by nephrostomy tube insertion to drain the obstructed kidney(s)...

BACKGROUND: Continent ileostomy is a solution for patients after proctocolectomy. OBJECTIVE: The aim of this study was to assess the long-term complications and failure rate alongside patient satisfaction, function, and quality of life for patients with a continent ileostomy. DESIGN: This was a retrospective, descriptive cross-sectional study. SETTINGS: All patients were operated in 1 center between 1980 and 2016. PATIENTS: A total of 85 patients received a de novo continent ileostomy in our institution...

Background and study aims  Restorative proctocolectomy has become the most common surgical option for patients with familial adenomatous polyposis (FAP). However, adenomas and even carcinomas may develop in the ileal pouch over time. The aim of this study was to evaluate the long-term incidence and nature of ileal pouch or distal ileal adenomas and carcinomas in patients with FAP. Patients and methods  This was a retrospective study of 47 FAP patients with Kock's continent ileostomy (Kock) (n = 8), ileorectal anastomosis (IRA) (n = 13), and ileal pouch-anal anastomosis (IPAA) (n = 26)...

A step-wise, 'test-all-positive-gluten' analytical methodology has been developed and verified to assess kernel-based gluten contamination (i.e., wheat, barley and rye kernels) during gluten-free (GF) oat production. It targets GF claim compliance at the serving-size level (of a pouch or approximately 40-50g). Oat groats are collected from GF oat production following a robust attribute-based sampling plan then split into 75-g subsamples, and ground. R-Biopharm R5 sandwich ELISA R7001 is used for analysis of all the first15-g portions of the ground sample...

OBJECTIVES: To report the long-term survival of transplanted kidneys in patients with a continent urinary diversion. METHODS: Between January 1987 and July 2015, 16 patients with a median age of 37 years (range 21-63 years) underwent kidney transplantation on a continent urinary diversion. A total of 14 patients presented irreversible dysfunction of the lower urinary tract, and two patients had required radical cystectomy because of bladder cancer. All continent urinary diversions were carried out before the transplantation...

PURPOSE: To investigate the long-term cumulative incidence of chronic urinary retention (CUR) after radical cystectomy (RC) and orthotopic neobladder (ONB) in women and the possible risk factors. MATERIAL AND METHODS: We retrospectively analyzed a prospectively evaluated cohort of women for whom RC and ONB were performed. Patients in CUR were evaluated for the cumulative incidence of CUR using Kaplan-Meier curve and for the possible risk factors using log rank and Cox regression analysis...

Pasteurella multocida is a gram-negative organism that commonly colonizes the mouth of cats and dogs, and is known to cause infection in humans associated with animal bites or scratches. Sites of infection other than skin and soft tissue are rare, but have been reported in patients with specific risk factors including anatomical abnormalities or immunosuppression. Herein, we report a case of a symptomatic urinary tract infection caused by P. multocida in a 59 year old female who presented to the hospital with complaints of systemic symptoms including malaise, rigors, and chills, as well as thick, malodorous urine...

OBJECTIVE: The aim of this study was to review different management modalities and outcome of patients presenting with late intestinal obstruction (IO) after radical cystectomy (RC) or palliative cystectomy (PC). MATERIALS AND METHODS: Files of patients who presented with IO between January 1978 and June 2014 were reviewed. Patients who developed IO following either RC or PC more than 30 days after surgery were included. Patients' characteristics and management protocols were evaluated...
