Ileocaecal valve syndrome after surgery in adult patients: myth or reality?

AIM: The onset of symptoms after removal of the ileocaecal valve (ICV) may be perceived as an unwanted effect of surgery and induce patients to bring unnecessary litigation against surgeons. The aim of our study is to assess the real impact on the quality of life of patients whose ICV has been surgically removed, using three validated questionnaires. METHOD: In patients who had their ICV removed surgically, the Gastrointestinal Quality of life (GIQLI) questionnaire and those used by the European Organization for research and Treatment of Cancer (EORTC) were administered before and after surgery. The empirical rule effect size method was used to evaluate the clinical significance of the statistical data. RESULTS: We interviewed 225 patients. Data collected through the three questionnaires highlighted a trend towards postoperative improvement of the selected gastrointestinal symptoms compared with the baseline. The GIQLI questionnaire showed a statistically significant improvement in 'pain', 'nausea' and 'constipation' during the follow-up. Constipation appeared more frequently in patients older than 70 years compared with younger ones. The EORTC-QLQ-C30 questionnaire showed a significant correlation between diarrhoea and extended right colectomy at 3 months after surgery, which was not confirmed at 6 months. The EORTC QLQ-CR29 questionnaire showed a slight deterioration of 'leakage of stools from the anal opening' at 6 months after surgery, but this symptom was not deemed clinically significant. CONCLUSION: We found that bowel functions in most patients after surgical removal of the ICV were satisfactory. Providing patients with a comprehensive and exhaustive informed consent during preoperative consultations could promote patient trust and avoid misunderstandings.

Self-adhesive mesh for Lichtenstein inguinal hernia repair. Experience of a single center.

AIM: Lichtenstein tension-free mesh repair is the most frequently performed procedure for inguinal hernioplasty. In the past surgery aimed to control recurrences. Nowadays it is important to avoid postoperative chronic pain and thus several studies have examined the potential role of meshes in causing postoperative pain. The purpose of this study was to retrospectively assess the early and long-term results after Lichtenstein tension-free repair using a self-adhesive mesh (Parietex ProgripTM - Covidien, Germany) in a single center. METHODS: The study enrolled 211 patients, 199 males (94.3%) and 12 females (5.7%), mean age 62 years (28-90 years), between January 2008 and December 2011. Of these, 206 had primary inguinal hernias while 5 were recurrences following previous tension repair. Ten different general surgeons, including residents, performed Lichtenstein hernia repair using a 12 x 8-cm Parietex ProgripTM mesh. In 88.1% of patients no additional fixation was used, while in 11.9% a single 2-0 polypropylene stitch was placed on the pubic bone. A 1-10 visual analog scale (VAS) was used to assess postoperative pain, evaluating it at 1 week, 1 month and 12, 24 and 36 months. Local paresthesia was assessed at same intervals. Any pain sensation lasting longer than 3 months postoperatively, or requiring injection of analgesics was defined as chronic pain. RESULTS: Mean operating time was 64.1 minutes (SD ± 21.14). There were no intraoperative complications. Early postoperative complications included hematoma-seroma (5.7% cases), superficial wound infection (1%), urinary retention (0.5%), and scrotal swelling (1%). The main follow-up period was 3 years, although patients operated between 2009 and 2011 underwent a shorter follow-up. At one-year follow-up, 17 patients reported groin discomfort, but did not require analgesics. Three patients reported moderate pain, requiring occasional use of oral analgesics, and 2 of these described a discontinuous pain mainly during movement. One patient reported severe pain requiring local injection of analgesics. At 2-year follow-up, 3 patients reported groin discomfort. Five of the 17 patients who reported discomfort at 1 year were lost to the 2-year follow-up. One patient kept reporting a high VAS score (6), though slightly reduced from the previously reported at 1-year follow-up. Recurrence was observed in 0.5% at 1 year and in 2.4% at 2 years. At 3 years only half of the patients (102) were still on follow-up. Of these, 1 reported mild discomfort and 3 developed hernia recurrence. Globally a decrease in pain and local discomfort was observed. No cases of seroma, testicular complications or mesh infection were reported at 1-, 2- and 3-year follow-up. CONCLUSION: Self-gripping mesh for inguinal hernia repair is a good and safe option, easy to handle and with a low incidence of chronic pain (<3%). A sutureless fixation seems to prevent the development of postoperative chronic pain, without increasing recurrence rates. Using a self-adhesive mesh also slightly reduce operating times, and costs are lower when compared to biological glue used to fix the mesh. In conclusion, our experience with the self-gripping mesh is limited but positive, randomized clinical trials are warranted to confirm our results.

Impact of the Italian Society of Anatomic Pathology and Diagnostic Cytology Classification of Thyroid Nodules in the Treatment of Indeterminate Follicular Lesions: Five-Year Results at a Single Center.

PURPOSE: Aim of the study was to assess the impact of the Italian Society of Anatomic Pathology and Diagnostic Cytology (SIAPEC) classification of 2014, on the treatment of indeterminate thyroid lesions (TIR3). METHODS: We retrospectively analyzed patients undergoing thyroid surgery for TIR3 lesions between 2013 and 2018, at the General Surgery Department of Trieste University Hospital. According to the SIAPEC classification, patients were divided into TIR3A and TIR3B groups. All patients treated before 2014 underwent surgical treatment, and surgical specimens were retrospectively classified after revision of fine-needle aspiration cytology. Starting 2014, TIR3A patients were treated only when symptomatic (i.e., coexistent bilateral thyroid goiter or growing TIR3A nodules), whereas TIR3B patients always received surgical treatment. Hemithyroidectomy (HT) was the procedure of choice. Total thyroidectomy (TT) was performed in case of concurrent bilateral goiter, autoimmune thyroid disease, and/or presence of BRAF and/or RAS mutation. Lastly, we analyzed the malignancy rate in the two groups. RESULTS: 29 TIR3A and 90 TIR3B patients were included in the study. HT was performed in 10 TIR3A patients and 37 TIR3B patients, respectively, with need for reoperation in 4 TIR3B (10.8%) patients due to histological findings of follicular thyroid carcinoma >1 cm. The malignancy rates were 17.2% in TIR3A and 31.1% in TIR3B, (p = 0.16). Predictability of malignancy was almost 89% in BRAF mutation and just 47% in RAS mutation. CONCLUSIONS: The new SIAPEC classification in association with biomolecular markers has improved diagnostic accuracy, patient selection, and clinical management of TIR3 lesions.

Partial thyroidectomy for papillary thyroid microcarcinoma: Is completion total thyroidectomy indicated?

AIM: Papillary thyroid microcarcinoma (PTMC) is increasing in incidence. Despite its excellent clinical outcomes, there is still debate regarding which surgical approach is more appropriate for PTMC, procedures including hemithyroidectomy (HT), total thyroidectomy (TT), and completion thyroidectomy (CT) after initial HT and histopathologic examination confirming a PTMC. Here we report our experience in the surgical management of PTMC. METHODS: We conducted a retrospective evaluation of all patients who received a postoperative diagnosis of PTMC between January 2001 and January 2016. Every patient was divided according to the type of surgery performed (TT or HT alone). Follow-up consisted of regular clinical and neck ultrasonographic examination. Clinical and histopathological parameters (e.g. age, sex, lesion size, histological features, multifocality, lymph node metastases, BRAF status when available) as well as clinical outcomes (e.g. complications rates, recurrence, overall survival) were analyzed. RESULTS: Group A consisted of 86 patients who underwent TT, whereas Group encompassed 19 patients who underwent HT. Mean follow-up period was 58.5 months. In Group A, one patient (1.2%) experienced recurrence in cervical lymph nodes with need for reoperation. In Group B, eight patients (42%) underwent completion thyroidectomy after histopathological examination confirming PTMC, while one patient (5.3%) developed PTMC in the contralateral lobe with need for reoperation at 2 years after initial surgery. Multifocality was found in 19 patients in Group A (22%). Of these, 14 presented bilobar involvement, whereas in 3 cases multifocality involved only one lobe. 1 patient in Group B (5.3%) presented with unilateral multifocal PTMC (p = 0.11). CONCLUSIONS: Low-risk patients with PTMC may benefit from a more conservative treatment, e.g. HT followed by close follow-up. However, appropriate selection of patients based on risk stratification is the key to differentiate therapy options and gain better results.

Rationality in prophylactic central neck dissection in clinically node-negative (cN0) papillary thyroid carcinoma: Is there anything more to say? A decade experience in a single-center.

AIM: Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy. Despite its extremely favorable prognosis, cervical lymph node metastases are a common feature of PTC and a known independent risk factor for local recurrence. However, the role of prophylactic central neck dissection (PCND) remains a matter of debate in patients with clinically node-negative (cN0) PTC. To better clarify the current role of PCND in the surgical treatment of PTC, evaluating advantages and disadvantages of PCND and outcome of cN0 PTC patients who have been treated with either total thyroidectomy alone or in combination with PCND. A review of recent literature data is performed. METHODS: Between January 2000 and December 2015, 186 consecutive patients with cN0 PTC were identified to be included in the present study. 74 of these underwent total thyroidectomy associated with PCND, while 112 patients underwent total thyroidectomy alone. The epidemiological and clinical-pathological data of all patients included were collected at diagnosis and during follow-up. RESULTS: Overall complication rate was significantly higher in the group of patients undergoing PCND (39.2% vs. 17.8%, p = 0.0006). To be specific, they presented a considerably increased risk of temporary recurrent laryngeal nerve injury (p = 0.009) and of permanent hypothyroidism (p = 0.016). Overall survival and recurrence rates did not differ between those undergoing PCND and those undergoing total thyroidectomy alone (p = 1.000 and p = 0.715, respectively). CONCLUSIONS: The results of the present study do not support the routine use of PCND in the treatment of cN0 PTC patients.
