Protective ileostomy creation after anterior resection of the rectum: Shared decision-making or still subjective?

AIM: The choice of whether to perform protective ileostomy (PI) after anterior resection (AR) is mainly guided by risk factors (RFs) responsible for the development of anastomotic leakage (AL). However, clear guidelines about PI creation are still lacking in the literature and this is often decided according to the surgeon's preferences, experiences or feelings. This qualitative study aims to investigate, by an open-ended question survey, the individual surgeon's decision-making process regarding PI creation after elective AR. METHOD: Fifty four colorectal surgeons took part in an electronic survey to answer the questions and describe what usually led their decision to perform PI. A content analysis was used to code the answers. To classify answers, five dichotomous categories (In favour/Against PI, Listed/Unlisted RFs, Typical/Atypical, Emotions/Non-emotions, Personal experience/No personal experience) have been developed. RESULTS: Overall, 76% of surgeons were in favour of PI creation and 88% considered listed RFs in the question of whether to perform PI. Atypical answers were reported in 10% of cases. Emotions and personal experience influenced surgeons' decision-making process in 22% and 49% of cases, respectively. The most frequently considered RFs were the distance of the anastomosis from the anal verge (96%), neoadjuvant chemoradiotherapy (88%), a positive intraoperative leak test (65%), blood loss (37%) and immunosuppression therapy (35%). CONCLUSION: The indications to perform PI following rectal cancer surgery lack standardization and evidence-based guidelines are required to inform practice. Until then, expert opinion can be helpful to assist the decision-making process in patients who have undergone AR for adenocarcinoma.

Quality-of-life impairment after endoluminal locoregional resection and laparoscopic total mesorectal excision.

BACKGROUND: For selected patients with rectal cancer, endoluminal locoregional resection (ELRR) by transanal endoscopic microsurgery (TEM) may be an alternative treatment option to laparoscopic total mesorectal excision (LTME). Few data are available on quality of life (QoL) after LTME and TEM. This study aimed to compare short- and medium-term QoL for T1 rectal cancer patients undergoing LTME or ELRR by TEM. METHODS: This study investigated 35 patients with T1N0 rectal cancer who underwent TEM (n = 17) or LTME (n = 18). Quality of life was evaluated by European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and QLQ-C38 questionnaires preoperatively and then 1, 6, and 12 months after surgery. RESULTS: Observation 1 month after LTME showed worsening in all items of both questionnaires. After ELRR, the QLQ-CR38 showed worsening of gastrointestinal (p = 0.005) and defecation problems (p = 0.001), and the QLQ-C30 showed worsening of global health status (p = 0.014), physical functioning (p = 0.02) role functioning (p = 0.003), fatigue (p = 0.002), and pain (p = 0.001). The QLQ-CR38 6 months after LTME showed worsening of body image (p = 0.009), micturition (p = 0.035), and gastrointestinal problems (p = 0.011), and the QLQ-C30 showed worsening of physical functioning (p = 0.003), role functioning (p = 0.002), fatigue (p = 0.004), and nausea/vomiting (p = 0.030). After ELRR, neither the QLQ-CR38 nor the QLQ-C30 questionnaire showed any worsening but demonstrated improvement in global health status and physical functioning. The QLQ-CR38 12 months after LTME showed significant improvement in defecation problems (p = 0.004) and weight loss (p = 0.003), and the QLQ-C30 showed significant improvement in global health status (p = 0.001), nausea and vomiting (p = 0.003), and pain (p = 0.005). After ELRR, the QLQ-C30 showed improvement in emotional functioning (p = 0.012), whereas no significant difference was observed by the QLQ-C38. CONCLUSIONS: Functional sequelae are present up to 1 month only after ELRR by TEM and up to 6 months after LTME. At 12 months, neither procedure showed a significant difference in QoL compared with preoperative status.

Establishing a successful clinical research program.

Clinical research (CR) is a natural corollary to clinical surgery. It gives an investigator the opportunity to critically review their results and develop new strategies. This article covers the critical factors and the important components of a successful CR program. The first and most important step is to build a dedicated research team to overcome time constraints and enable a surgical practice to make CR a priority. With the research team in place, the next step is to create a program on the basis of an original idea and new clinical hypotheses. This often comes from personal experience supported by a review of the available evidence. Randomized controlled (clinical) trials are the most stringent way of determining whether a cause-effect relationship exists between the intervention and the outcome. In the proper setting, translational research may offer additional avenues allowing clinical application of basic science discoveries.

Biomaterials in the treatment of anal fistula: hope or hype?

Anal fistula (AF) presents a chronic problem for patients and colorectal surgeons alike. Surgical treatment may result in impairment of continence and long-term risk of recurrence. Treatment options for AFs vary according to their location and complexity. The ideal approach should result in low recurrence rates and minimal impact on continence. New technical approaches involving biologically derived products such as biological mesh, fibrin glue, fistula plug, and stem cells have been applied in the treatment of AF to improve outcomes and decrease recurrence rates and the risk of fecal incontinence. In this review, we will highlight the current evidence and describe our personal experience with these novel approaches.

Asymptomatic pneumoperitoneum or pneumatosis cystoides intestinalis? Easy to make a mistake.

Pneumoperitoneum refers to the presence of intraperitoneal free gas outside the viscera. A perforation of a hollow viscus is the main cause and usually indicates a surgical emergency. However, some case of pneumoperitoneum can be completely asymptomatic and secondary to benign conditions that do not require any surgical intervention. In this situation a misleading diagnosis of pneumoperitoneum may occur. The authors are going to present a case of a 79-year-old man with an asymptomatic pneumoperitoneum incidentally detected by CT-scan and subsequently revealed to be pneumatosis cystoides intestinalis (PCI) at diagnostic laparoscopy. PCI is a rare condition characterized by the presence of gas-filled cyst in the submucosa/subserosa of the bowel wall that can easily mimic pneumoperitoneum on radiological imaging. A thorough examination of radiological findings is crucial in preventing unnecessary surgical procedures that may expose patients to potential associated morbidities.

[Transanal endocopic microsurgery (TEM) in advanced rectal cancer disease treatment]. / Il ruolo della TEM nel trattamento dei tumori del retto extraperitoneale.

After Heald's revolution in 1982, who introduced the total mesorectal excision, for improve the results in terms of recurrance and survival rate, there is a need to explore new therapeutic options in treatment of sub-peritoneal rectal cancer. In particular, local excision represent more often a valid technique for non advanced rectal cancer treatment in comparison with the more invasive procedure, especially in elderly and/or in poor health patients. The introduction of TEM by Buess (transanal endoscopy microsurgery), has extended the local treatment also to classes of patients who would normally have been candidates for TME. The author gives literature's details and his experience in the use of TEM for early rectal cancer sub-peritoneal. The aim of the study is to analyze short and long term results in terms of local recurrence and survival rate comparing TEM technique with the other transanal surgery in rectal cancer treatment. Preoperative Chemio-Radio therapy and rigorous Imaging Staging are the first steps to planning surgery. It's time, for local rectal cancer, has come to make the devolution a few decades ago has been accomplished in the treatment of breast cancer

Surgical treatment of ulcerative colitis: ileorectal vs ileal pouch-anal anastomosis.

Total proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the current gold standard in the surgical treatment of ulcerative colitis (UC) refractory to medical management. A procedure of significant magnitude carries its own risks including anastomotic failure, pelvic sepsis and a low rate of neoplastic degeneration overtime. Recent studies have shown that total colectomy with ileorectal anastomosis (IRA) has been associated with good long-term functional results in a selected group of UC patients amenable to undergo a strict surveillance for the relatively high risk of cancer in the rectum. This manuscript will review and compare the most recent literature on IRA and IPAA as it pertains to postoperative morbidity and mortality, failure rates, functional outcomes and cancer risk.

Laparoscopic transperitoneal anterior adrenalectomy.

AIM: Aim of this study was to report the authors' experience with the anterior transperitoneal approach, and with an anterior submesocolic approach in case of left sided lesions. MATERIAL AND METHODS: From January 1994 to January 2011, 122 males and 170 females with a mean age of 50.7 years (range: 19-84) underwent laparoscopic adrenalectomy (LA) at 2 centers in Ancona and Rome (Italy) (that follow the same protocol). Fifteen patients underwent bilateral LA, the anterior transperitoneal approach was used in 233 cases (79.8%) and the anterior submesocolic in 59 (20.2%). One hundred and two patients had Conn's syndrome, 51 miscellaneous lesions, 55 Cushing's syndrome, 47 incidentalomas, 46 pheochromocytoma, 2 metastatic masses, 2 myelolipomas and 2 adrenogenital syndromes. The lesions had a mean diameter of 3.24 cm (range: 0.5-10). RESULTS: Mean operating time was 120 minutes (range: 30-390). Conversion to open surgery was required in 13 cases (4,45%). Blood pressure and heart rate were stable during the operation. There were 5 major complications. Mobilization and resumption of diet occurred on the first postoperative day. Mean hospital stay was 4.32 days (range: 2-30). DISCUSSION: Early identification and ligature of the adrenal vein, with minimal gland manipulation, are the major advantages, especially in case of pheochromocytoma. CONCLUSIONS: Adrenal masses can be successfully treated using a laparoscopic transperitoneal anterior approach, in presence of a suitable anesthesiological and surgical team's experience. KEY WORDS: Adrenal tumors, Laparoscopic adrenalectomy, Pheochromocytoma.

Breast myofibroblastoma in a young woman: a case report.

Myofibroblastoma (MFB) is an uncommon benign mesenchymal tumor that may arise in several organs and tissue. Although most of reported cases were located in the breast, it is extremely rare, representing less than 1% of breast tumor. MFB has predominantly seen in elderly men, but some cases have been described in menopausal women. This lesion is a stromal tumor which has many morphologic variants including cellular, collagenized, epithelioid, palisaded, lipomatous, hemangiopericytoma-like, and infiltrant features. Even if its incidence has recently increased due to the mammary screening, only few cases have been reported in Literature and even less in young women. Physical examination discloses a solitary, unilateral, painless, freely movable, usual firm in consistency, non-tender nodule. Imaging investigations usually are not specific to establish the right diagnosis. Furthermore, findings from Fine-Needle Aspiration (FNA) may be confusing and nonspecific, making diagnosis of MFB possible only after surgical operation. Not evidence of malignant transformation, recurrence or distant metastasis after a follow-up period of 15 years have been reported in Literature when resection margins are free. Hereby the authors describe a rare case of breast MFB in a young woman.
