Quality of Life After Total Mesorectal Excision and Rectal Replacement: Comparing Side-to-End, Colon J-Pouch and Straight Colorectal Reconstruction in a Randomized, Phase III Trial (SAKK 40/04).

BACKGROUND: Functional outcomes of different reconstruction techniques have an impact on patients' quality of life (QoL), but information on long-term QoL is lacking. We compared QoL among three reconstruction techniques after total mesorectal excision (TME). METHODS: Quality of life was assessed within a randomized, multicenter trial comparing rectal surgery using side-to-end anastomosis (SEA), colon J-pouch (CJP), and straight colorectal anastomosis (SCA) by the Functional Assessment of Cancer Therapy-Colorectal scale (FACT-C) before randomization and every 6 months up to 2 years post-TME. The primary QoL endpoint was the change in the Trial Outcome Index (TOI), including the FACT-C subscales of physical and functional well-being and colorectal cancer symptoms (CSS), from baseline to month 12. Pair-wise comparisons of changes from baseline (presurgery) to each timepoint between the three arms were analyzed by Mann-Whitney tests. RESULTS: For the QoL analysis, 257 of 336 randomized patients were in the per protocol evaluation (SEA = 95; CJP = 63; SCA = 99). Significant differences between the reconstruction techniques were found for selected QoL scales up to 12 months, all in favor of CJP. Patients with SEA or SCA reported a clinically relevant deterioration for TOI and CSS at 6 months, those with SCA for CSS also at 12 months after TME. Patients with CJP remained stable. CONCLUSIONS: Although the three reconstruction techniques differ in their effects on QoL at months 6 and 12, these differences did not persist over the whole observation period of 24 months. Patients with a colon J-pouch may benefit with respect to QoL in the short-term.

Jejuno-ileal diverticulitis: A disorder not to underestimate.

INTRODUCTION: Jejuno-ileal diverticulitis is an uncommon, acquired clinical entity, with higher prevalence among patients aged between 60 and 70. The condition is usually silent and has been regarded as relatively innocuous. Sometimes patients complain chronic vague symptoms like malabsorption, pain or nausea, that easily lead to misdiagnosis. Acute complications are rare, however, they have been reported and can result in major surgery and high overall mortality. CASE REPORT: We are presenting a case of a 67-year-old patient who presented to our department with abdominal pain and signs of peritonitis. The CT scan displayed an inflammatory mass with a fair amount of free liquid in the abdomen, as well as multiple diverticula at different levels of the intestine. The patient had to underwent immediate surgery, during which a resection of 25 cm jejunum and 80 cm of ileum has been performed. CONCLUSION: Jejuno-ileal diverticula are a very uncommon finding that can present formidable challenges in diagnosis and treatment. The course can be completely asymptomatic, however, in rare cases, the condition can lead to severe complications that often require surgery. Multi detector CT (MDCT) with intravenous contrast should always be the modality of choice for investigating a suspect of small bowel diverticula. There are no specific guidelines respect the management of jejuno-ileal diverticulitis, nevertheless, in the acute setting, bowel resection is the treatment of choice. As well as setting out the rarity of this case, our work intends to review the current literature regarding the epidemiology, natural history, diagnosis and management of jejuno-ileal diverticula.

Endoscopic pilonidal sinus treatment (EPSiT) in recurrent pilonidal disease: a prospective international multicenter study.

BACKGROUND: Pilonidal disease (PD) is a common disease of the natal cleft, which can lead to complications including infection and abscess formation. Various operative management options are available, but the ideal technique is still debatable. Recurrent PD after surgical treatment is frequent event for the 25-30% of cases. The present study evaluated endoscopic pilonidal sinus treatment (EPSiT) in recurrent and multi-recurrent PD. METHODS: Of the consecutive prospective patients with recurrent PD, 122 were enrolled in a prospective international multicenter study conducted at a secondary and tertiary colorectal surgery centers. Primary endpoint was to evaluate short- and long-term outcomes: healing rate/time, morbidity rate, re-recurrence rate, and patient's quality of life (QoL). RESULTS: Complete wound healing rate was occurred in 95% of the patient, with a mean complete wound healing time of 29 ± 12 days. The incomplete healing rate (5%) was significantly related to the number of external openings (p = 0.008), and recurrence was reported in six cases (5.1%). Normal daily activity was established on the first postoperative day, and the mean duration before patients returned to work was 3 days. QoL significantly increased between the preoperative stage and 30 days after the EPSiT procedure (45.3 vs. 7.9; p < 0.0001). CONCLUSIONS: The EPSiT procedure seems to be a safe and effective technique in treating even complex recurrent PD. It enables excellent short- and long-term outcomes than various other techniques that are more invasive.

Clinical Outcome After Rectal Replacement With Side-to-End, Colon-J-Pouch, or Straight Colorectal Anastomosis Following Total Mesorectal Excision: A Swiss Prospective, Randomized, Multicenter Trial (SAKK 40/04).

OBJECTIVE: To compare, in a phase 3, prospective, randomized, multi-center clinical trial functional outcome of reconstruction procedures following total mesorectal excision (TME). SUMMARY BACKGROUND DATA: Intestinal continuity reconstruction following TME is accompanied by postoperative defecation dysfunctions known as "anterior resection syndrome." Commonly used reconstruction techniques are straight colorectal anastomosis (SCA), colon J -pouch (CJP), and side-to-end anastomosis (SEA). Comparison of their functional outcomes in prospective, randomized, multi-center studies, including long-term assessments, is lacking. METHODS: Patients requiring TME for histologically proven rectal tumor, with or without neoadjuvant treatment, age ≥ 18 years, normal sphincter function without history of incontinence, any pretreatment staging or adenoma, expected R0-resection, were randomized for standardized SCA, CJP, or SEA procedures. Primary endpoint was comparison of composite evacuation scores 12 months after TME. Comparison of composite evacuation and incontinence scores at 6, 18 and 24 months after surgery, morbidity, and overall survival represented secondary endpoints. Analysis was based on "per protocol" (PP) population, fully complying with trial requirements, and intention-to treat (ITT) population. RESULTS: Three hundred thirty-six patients from 15 hospitals were randomized. PP population included 257 patients (JCP = 63; SEA = 95; SCA = 99). Composite evacuation scores of PP and ITT populations did not show statistically significant differences among the 3 groups at any time point. Similarly, composite incontinence scores for PP and ITT populations showed no statistically significant difference among the 3 trial arms at any time point. CONCLUSIONS: Within boundaries of investigated procedures, surgeons in charge may continue to perform reconstruction of intestinal continuity following TME at their technical preference.

Gallstone ileus: A possible cause of bowel obstruction in the elderly population.

INTRODUCTION: Gallstone ileus (GI) is characterized by a mechanical occlusion of the ileal lumen as a result of migration of one or more gallstones in the intestinal tract. Less than 1-4% of all cases of intestinal obstruction are derived from this etiology (1,2,3). CASE REPORT: We present a case of small intestinal obstruction owing to a large gallstone in lower ileum in a 66 years old woman. The diagnosis was made by computed tomography, and treated successfully with an enterotomy, with a removal of a 5 cm gallstone, carried out through a longitudinal incision on the antimesenteric border. Post-operative course presented no adverse effects. CONCLUSION: Gallstone ileus should be considered in case of bowel obstruction in the elderly population. Abdominal CT scan is the preferred investigation for a timely diagnosis.

Umbilical metastasis mimicking symptomatic hernia: Report of a case of Sister Mary Joseph Syndrome.

INTRODUCTION: An umbilical mass can be the first symptom of an intra-abdominal neoplasia, and this condition is also defined as Sister Mary Joseph Syndrome. CASE PRESENTATION: An eighty-year-old patient presented with a complicated umbilical hernia. CT scan abdomen revealed a pancreatic neoplasm and an umbilical biopsy confirmed diagnosis of metastasis. Patient started chemotherapy by Oncologists. CONCLUSIONS: In this paper the Authors suggest a histopathological evaluation of umbilical fat in all cases of newly emerging umbilical hernia in the adult population.

(99m)Tc-MIBI Uptake in a Thyroid Adenoma with Diffuse Adipose Metaplasia.

A 71-year-old female underwent a (99m)Tc-MIBI scan to characterize a cold nodule (30 mm) of the left thyroid lobe. The nodule showed diffuse uptake and retention of the radiotracer. After resection, histological examination demonstrated a microfollicular adenoma with diffuse white adipose metaplasia. Although mitochondria in brown adipose tissue have been widely studied, we have only a limited understanding of the relevance of mitochondria in white adipose tissue. Active mitochondria are present in white adipocytes, and this may account for the MIBI uptake, mimicking a hyperproliferation pattern, in our patient.

Obturator hernia with ureteral entrapment.

Obturator hernia of the ureter is uncommon. Computed tomography of a 77-year-old woman with sudden-onset lower left abdominal pain and urinary symptoms showed an obturator hernia with ureteral entrapment. Obturator hernia is a diagnostic challenge because the hernial mass is very insidious. It should be suspected in emaciated, multiparous, elderly women presenting with unexplained pain in the groin, hip, thigh or knee. High levels of clinical suspicion of high-risk patients and recourse to investigation by computed tomography are important, as delay in diagnosis and treatment is associated with increased morbidity and mortality.

Electrocardiographic changes and false-positive troponin I in a patient with acute cholecystitis.

Cardiac troponins are the most sensitive and specific serum markers of myocardial cell injury, but they can also arise without apparent cardiac injury. Besides, acute cholecystitis may be associated with nonspecific ST-T wave changes in electrocardiography (ECG). The signs and symptoms of gallbladder and heart disease may overlap, which can make diagnosis difficult. We describe the case of a 75-year-old woman with clinical features suggestive of acute cholecystitis associated with transient ST segment elevation and elevated troponin I that, after extensive workup, did not seem to be attributable to myocardial ischemia or any other acute cardiac problem, but were exclusively related to cholecystitis. We show that cholecystitis with gallbladder distension can be the sole cause of pathological ECG changes and an increased troponin I level; this should be considered when evaluating patients with similar presentations.

Hyperfunctioning solid/trabecular follicular carcinoma of the thyroid gland.

A 68-year-old woman with solid/trabecular follicular thyroid carcinoma inside of an autonomously functioning thyroid nodule is described in this paper. The patient was referred to our clinic for swelling of the neck and an increased pulse rate. Ultrasonography showed a slightly hypoechoic nodule in the right lobe of the thyroid. Despite suppressed TSH levels, the (99m)Tc-pertechnetate scan showed a hot area corresponding to the nodule with a suppressed uptake in the remaining thyroid tissue. Histopathological examination of the nodule revealed a solid/trabecular follicular thyroid carcinoma. To the best of our knowledge, this is the first case of hyperfunctioning follicular solid/trabecular carcinoma reported in the literature. Even if a hyperfunctioning thyroid carcinoma is an extremely rare malignancy, careful management is recommended so that a malignancy will not be overlooked in the hot thyroid nodules.

Effect of timing of surgery on survival after preoperative hyperfractionated accelerated radiotherapy (HART) for locally advanced rectal cancer (LARC): is it a matter of days?

We intend to analyse retrospectively whether the time interval ("gap duration" = GD) between preoperative radiotherapy and surgery in locally advanced rectal cancer (LARC) has an impact on overall survival (OS), cancer specific survival (CSS), disease free survival (DFS) and local control (LC). Two hundred seventy nine patients with LARC were entered in Trial 93-01 (hyperfractionated accelerated radiotherapy 41.6 Gy/26 Fx BID) shortly followed by surgery. From these 250 patients are fully assessable. The median GD of 5 days was used as a discriminator. The median follow-up for all patients was 39 months. GD > 5 days was a significant discriminator for actuarial 5-years OS (69% vs 47%, p = 0.002), CSS (82% vs 57%, p = 0.0007), DFS (62% vs 41%, p = 0.0003) but not for LC (93% vs 90%, p = non-significant). In multivariate analysis, the following factors independently predict outcome; for OS: age, GD, circumferential margin (CM) and nodal stage (ypN); for CSS: GD, ypN and vascular invasion (VI); for DFS: CEA, distance to anal verge, GD, ypN and VI; for LC: CM only. Gap duration predicts survival outcome but not local control. The patients submitted to surgery after a median delay of more than 5 days had a significantly better outcome.

Preoperative hyper-fractionated accelerated radiotherapy (HART) in locally advanced rectal cancer (LARC) immediately followed by surgery. A prospective phase II trial.

BACKGROUND AND PURPOSE: We aim to report on local control in a phase II trial on preoperative hyper-fractionated and accelerated radiotherapy schedule (HART) in locally advanced resectable rectal cancer (LARC). This fractionation schedule was designed to keep the overall treatment time (OTT) as short as possible. PATIENTS AND METHODS: This is a prospective trial on patients with UICC stages II and III rectal cancer. The patients were submitted to a total dose of 41.6 Gy, delivered in 2.5 weeks at 1.6 Gy per fraction twice a day with a 6-h interfraction interval. Surgery was performed within 1 week after the end of irradiation. Adjuvant chemotherapy was delivered in a subset of patients. RESULTS: Two hundred and seventy nine patients were entered and 250 are fully assessable, with a median follow-up of 39 months. The 5-years actuarial local control (LC) rate is 91.7%. The overall survival (OS) is 59.6%. The freedom from disease relapse (FDR) is 71.5%. Downstaging was observed in 38% of the tumors. CONCLUSION: The actuarial LC at 5 years is 91.7%, although we are dealing with stages II-III LARC, mainly located in the lower rectum (median distance = 5 cm). The pattern of failure is dominated by distant metastases and treatment intensification will obviously require a systemic approach.
