Opis:: Objectives: Females with unresectable rectal cancer have a poor prognosis. In some cases curative treatment for tumors infiltrating the internal genitalia (T4) may be achieved with multivisceral excision. Radiochemotherapy combined with extended resection can improve local control and survival. Aim of the study was to evaluate long-term oncological outcomes of combined curative therapy with sphincter preservation for women with T4 rectal cancer, involving internal reproductive organs. Material and methods: Consecutive 21 females in years 1997-2003 underwent R0 anterior resection of the rectum with excision of internal genitalia in one tissue block combined with radiochemotherapy and were studied retrospectively. Two-year disease-free survival rates were analyzed in relation to patient age, tumor differentiation, lymph node metastases, blood loss, radial and distal resection margins. Results: Survival rate was significantly increased (p<0.05) for females after resections with distal margin minimum 1 cm and radial margin minimum 2 mm microscopically free of cancer infiltration (80.0 vs. 27.3% and 71.4 vs. 14.3%, respectively). Lymph node metastases also significantly influenced poor prognosis (85.7 vs. 35.7%). Age less than 60 years, well or moderate tumor differentiation and blood loss <1 L were related to enhanced survival but with the lack of statistical importance (66.7 vs. 41.8%, 55.6 vs. 55.0% and 75.0 vs. 47.1%, respectively). Conclusions: Extended surgery combined with radiochemotherapy may result in improved long-term outcome for females with T4 rectal cancer, infiltrating internal genitalia. Effective local control with adequate resection margins and node-negative status are significantly related to enhanced survival rates.
Wstęp: Rokowanie u pacjentek z nieresekcyjnym rakiem odbytnicy jest złe. W niektórych przypadkach miejscowo zaawansowanych guzów naciekających narząd rodny (T4) rozszerzone zabiegi operacyjne mogą być podjęte z intencją radykalności. Skojarzenie chirurgii z radio- i chemioterapią prowadzi do poprawy kontroli miejscowej i przeżyć długoterminowych. Celem pracy była ocena odległych wyników onkologicznych skojarzonego radykalnego leczenia z zaoszczędzeniem zwieraczy u kobiet z rakiem odbytnicy naciekającym narząd rodny. Materiał i metody: Retrospektywą analizą objęto kolejnych 21 kobiet poddanych w latach 1997-2003 przedniej resekcji R0 odbytnicy i narządu rodnego w jednym bloku tkankowym skojarzonej z radiochemioterapią. Obliczono odsetki bezobjawowych przeżyć dwuletnich i ustalono ich korelację z wiekiem pacjentek, stopniem zróżnicowania histologicznego guza, obecnością przerzutów w okolicznych węzłach chłonnych, śródoperacyjną utratą krwi oraz wielkością dystalnych i radialnych marginesów resekcji. Wyniki: Odsetki przeżyć były znamiennie wyższe (p<0,05) u pacjentek po resekcjach z mikroskopowo wolnym od infiltracji nowotworowej marginesem dystalnym nie mniejszym niż 1 cm i radialnym co najmniej 2 mm (80,0 vs 27,3% i 71,4 vs 14,3%). Obecność przerzutów węzłowych także istotnie wpływała na pogorszenie rokowania (85,7 vs 35,7%). Wiek poniżej 60 lat, wysoki lub średni stopień dojrzałości guza oraz utrata krwi poniżej 1 l były związane z wyższymi odsetkami przeżyć, lecz bez statystycznej znamienności (66,7 vs 41,8%, 55,6 vs 55,0% i 75,0 vs 47,1%). Wnioski: Rozszerzone zabiegi operacyjne skojarzone z radiochemioterapią mogą poprawić wyniki odległe radykalnego leczenia raka odbytnicy T4 naciekającego narząd rodny. Skuteczna kontrola miejscowa osiągnięta dzięki adekwatnym marginesom resekcji jest wraz z brakiem przerzutów w węzłach chłonnych czynnikiem istotnie zwiększającym odsetki przeżyć długoterminowych.

Tematy:: faecal incontinence

Opis:: Damage to the sphincter, regardless of its pathogenesis, consists in the impossibility to control the physiology, or the so-called faecal incontinence. This implies changes in the whole bio-psycho-social functioning of the patients, and thus affects the satisfaction with their quality of life, conditioned by their health status. The problem affects around 5 to 7% of the population. Often enough, the only hope for those patients are repair procedures of the sphincter mechanism. The aim of the study was to evaluate key aspects of quality of life which determine the psycho-social status of patients with endogenous or iatrogenic sphincter damage in the perspective of a planned extensive sphincter’s repair procedure. Material and methods. The study group consisted of 52 people, 26 women and 26 men, aged 19–72. The scale by Rockwood – Fecal Incontinency Quality of Life – was used as the basic research tool which evaluates the quality of life in four aspects: 1/behavioral (Lifestyle) 2/cognitive (Coping) 3/emotional (Depression) 4/overall self-assessment (Embarrasment). The degree of incontinence was determined based on point scales of Jorge Wexner (JW scale) and the Fecal Incontinenece Severity Index (FISI scale). Structured diagnostic interview was also used in the study. Results. The results show that lack of control over the basic physiological functions disintegrates the quality of life in all evaluated aspects related to somatic, psychological and social functioning. FIQL: Lifestyle (LS) – 1.96 pts Coping (C) – 1.67 pts Depression (D) – 2.1 pts Embarrasment (E) – 1.79 pts Conclusions. The FIQL results presented explain the fact that among 52 patients followed, 50 decided to conduct extensive reconstructive procedures, although the results are not statistically optimistic and the risk of complications is relatively high

Opis:: Rectal prolapse is the partial or complete protrusion of the rectal wall into the anal canal. The most common etiology consists in the insufficiency of the diaphragm of the lesser pelvis and anal sphincter apparatus. Methods of surgical treatment involve perineal or abdominal approach surgical procedures. The aim of the study was to present the method of surgical rectal prolapse treatment, according to Mikulicz’s procedure by means of the perineal approach, based on our own experience and literature review. Material and methods. The study group comprised 16 patients, including 14 women and 2 men, aged between 38 and 82 years admitted to the department, due to rectal prolapse, during the period between 2000 and 2012. Nine female patients, aged between 68 and 82 years (mean age-76.3 years) with fullthickness rectal prolapse underwent surgery by means of Mikulicz’s method with levator muscle and external anal sphincter plasty. The most common comorbidities amongst patients operated by means of Mikulicz’s method included cardiovascular and metabolic diseases. Results. Mean hospitalization was 14.4 days (ranging between 12 and 17 days). Despite advanced age and poor general condition of the patients, complications during the perioperative period were not observed. Good early and late functional results were achieved. The degree of anal sphincter continence was determined 6-8 weeks after surgery showing significant improvement, as compared to results obtained prior to surgery. One case of recurrence consisting in mucosal prolapse was noted, being treated surgically by means of Whitehead’s method. Good treatment results were observed. Conclusion. Transperineal rectosigmoidectomy using Mikulicz’s method with levator muscle and external anal sphincter plasty seems to be an effective, minimally invasive and relatively safe procedure that does not require general anesthesia. It is recommended in case of patients with significant comorbidities and high surgical risk.

Opis:: The aim of the study was to assess the influence of neoadjuvant radiotherapy and resection of the rectum on the functional parameters of anal sphincters.Material and methods. 20 patients with rectal cancer, qualified for low anterior rectal resection with neoadjuvant radiotherapy were enrolled in the study group. The study protocol included an anorectal manometry, electromyography and fecal incontinence questionnaire (FISI) before radiotherapy, after radiotherapy, and after the operation.Results. Of the 20 patients 12 were included in the final analysis, because 8 patients were re-qualified to abdomino-perineal resection of the rectum after neoadjuvant treatment. There were no significant changes in anal pressures assessed 5 to 8 days after radiotherapy. In 3 cases (25%) pathological changes in RAIR reflex were found in the manometric examination. After low anterior resection mean basal anal pressures were significantly lower, whereas squeeze anal pressures did not change significantly. In 7 patients (58%) the RAIR reflex was pathological or even absent after low anterior resection. Changes in manometric parameters correlated with FISI incontinence assessment after the operation. In electromyographic examination action potentials of motoric units of the external anal sphincter were still present both after radiotherapy, and after operation.Conclusions. Fecal incontinence after low anterior resection of the rectum seems to be caused mostly by changes in autonomic functionality of anal sphincters and lack of compliance of the neorectum, since the influence of neoadjuvant radiotherapy and the operation itself on the somatic innervation of anal sphincters seems to be minimal.

Opis:: Authors tried to determine the role of an internal anal sphincter (IAS) in patients with rectoperineal fistula undergoing PSARP, with or without IAS-saving procedure. Materials and methods: 20 girls and 6 boys with rectoperineal fistula undergoing PSARP between 1993-2008 were included in the study. An IAS-saving operation was performed in 19 children (73.1%), 17 girls and 2 boys, while 7 children underwent regular PSARP with resection of narrowed distal portion of fistula. Results: Functional postoperative result according to the „10” score was good (8-10 pts.) in all 26 children. There was no significant difference in RAP (16.3 vs. 16.9 vs. 17.2 cmH2O) and ACL (1.7 vs. 1.7 vs. 1.9 cm) values between children with and without preserved IAS and the reference group. Positive RAIR was observed in 13 of 19 children with preserved IAS, and in 2 of 7 patients after resection of IAS, but this incidence did not differ statistically (p = 0.095). The major functional disorder in the examined children was constipation, observed in 9 children after sphincter-saving procedure and in 2 patients after regular PSARP, but the difference was not significant (p = 0.658). Conclusions: An IAS is important, but not a decisive factor in fecal continence and IAS-saving procedures are associated with high incidence of constipation. Authors suggest that IAS can be spared, wherever it was possible, i.e. the fistula is wide (at least 8 mm) and it will not impair function of the neoanus.
Autorzy podjęli próbę oceny roli zwieracza wewnętrznego odbytu (ZWO) u pacjentów z przetoką odbytniczo-kroczową po operacji wady odbytu metodą PSARP, z wycięciem lub oszczędzeniem ZWO. Materiały i metody: Badaniami objęto grupę 20 dziewczynek i 6 chłopców z przetoką odbytniczo-kroczową operowanych metodą PSARP w latach 1993-2008. Operację oszczędzającą ZWO przeprowadzono u 19 dzieci (73,1%), 17 dziewczynek i 2 chłopców, natomiast u 7 pacjentów wykonano operację PSARP z wycięciem zwężonego, dystalnego odcinka przetoki. Wyniki: Pooperacyjny wynik czynnościowy wg skali „10” był dobry (8-10 pkt.) u wszystkich 26 dzieci. Nie stwierdzono istotnej różnicy w wartościach RAP (16,3 vs. 16,9 vs. 17,2 cmH2O) i ACL (1,7 vs. 1,7 vs. 1,9 cm) u dzieci z i bez ZWO oraz grupą referencyjną. RAIR wywołano u 13 spośród 19 dzieci z zachowanym ZWO oraz u 2 spośród 7 pacjentów bez ZWO, bez różnicy statystycznej (p = 0,095). Najpoważniejszym zaburzeniem czynnościowym u dzieci były zaparcia obserwowane u 9 pacjentów z zachowanym ZWO i u 2 dzieci po klasycznej operacji PSARP, bez różnicy statystycznej (p = 0,658). Wnioski: ZWO jest ważnym, ale nie decydującym czynnikiem w mechanizmie trzymania stolca, a operacjom oszczędzającym ZWO towarzyszy wysoki odsetek zaparć w okresie pooperacyjnym. Autorzy sugerują oszczędzenie ZWO, jeżeli jest to możliwe, tzn. ujście przetoki jest szerokie (co najmniej 8 mm) i nie upośledza to czynności nowego odbytu.

Opis:: The aim of the study was to identify clinical factors which could influence the results of overlapping sphincteroplasty. Material and methods. Between 2003-2009 the group of 78 incontinent patients (59 women, mean age of 61±13 years), was operated on with anterior overlapping anal sphincteroplasty. Only patients with severe incontinence (>16 pts in Wexner scale) were included. Before surgery and in follow-up period anorectal ultrasound, manometry and incontinence assessment were performed and in follow-up period patients additionally fulfilled survey. The study was prospective. Follow up period was more than 36 months. Results. In survey the excellent results related to 52 patients (66.7%), good in 15 (19.2%) and poor in 11 (14.1%). The squeeze pressure improved more significantly in men 33±11 cm H2O vs. 22±14 cm H2O; p=0.039. In patients <50 year squeeze pressure was significantly larger 32±10 cm H2O vs. 25±12 cm H2O; p=0.045. If the width of a defect within sphincter was less than 60°飀 the improvement in squeeze pressure was higher 33±9 cm H2O vs. 22±15 cm H2O; p=0.031. In Wexner scale male patients better responded to surgery than females 6.94±1.8 vs. 5.12±2.2, p=0.048; as well as patients with smaller scar <60° 6.51±1.4 vs. 4.28±2.3; p=0.042. Conclusions. To succeed in sphincteroplasty the proper qualification to the procedure should be crucial. Clinical assessment prior to surgery with the use of all available non-surgical methods in patients suffer from severe symptoms can help to select optimal group who will benefit from surgery. Male patients may have to obtain better outcome and patients with smaller sphincter defect could likely have also better results from surgery.

Opis:: Anal fissure is one of the most common anorectal diseases resulting from a longitudinal tear in anoderm under the dentate line. It causes painful defecation and bleeding per anum. Most of the fissures heal by conservative means but a significant proportion turns chronic, leading to a negative impact upon the overall quality of life of a patient. The treatment options for chronic fissures are generally based on reducing the anal pressures and include non-surgical and surgical modalities. Lateral internal sphincterotomy still remains the gold standard for definitive management of anal fissure though anal incontinence is a serious complication of the procedure. In recent years, various modifications have evolved to minimize chances of incontinence besides the evolution of a wide range of non-surgical options of management. This review outlines the key points in the clinical presentation, etiopathogenesis, impact on the quality of life and management of anal fissure in the light of the recent updates in literature.
