Phenolization of the sinus tract in recurrent sacrococcygeal pilonidal sinus disease: long-term results of a prospective cohort study.

Aim: In recent years, the paradigm for the treatment of sacrococcygeal pilonidal sinus disease (SPSD) has shifted from surgical excision toward more minimally invasive techniques. Although extensive research has been conducted on the minimal invasive phenolization technique for primary SPSD, literature in recurrent SPSD is lacking. The purpose of this study was to report the long-term outcomes of the phenolization technique for recurrent SPSD.

Limited wedge resection for T1 colon cancer (LIMERIC-II trial) - rationale and study protocol of a prospective multicenter clinical trial.

Background: The sole presence of deep submucosal invasion is shown to be associated with a limited risk of lymph node metastasis. This justifies a local excision of suspected deep submucosal invasive colon carcinomas (T1 CCs) as a first step treatment strategy. Recently Colonoscopy-Assisted Laparoscopic Wedge Resection (CAL-WR) has been shown to be able to resect pT1 CRCs with a high R0 resection rate, but the long term outcomes are lacking.

Long-term Outcome of Radical Excision Versus Phenolization of the Sinus Tract in Primary Sacrococcygeal Pilonidal Sinus Disease: A Randomized Controlled Trial.

Background: Phenolization of pilonidal sinus disease has been shown to have advantages over radical excision with regard to short-term outcome; however, long-term outcomes are essentially lacking.

Objective: The aim of this randomized controlled trial was to compare the long-term outcome of pit excision and phenolization of the sinus tracts vs radical excision with primary wound closure in pilonidal sinus disease.

Design: Single-center, randomized controlled trial.

Colonoscopic-Assisted Laparoscopic Wedge Resection for Colonic Lesions: A Prospective Multicenter Cohort Study (LIMERIC-Study).

Objective: The aim of this study was to evaluate the safety and efficacy of a modified CAL-WR.

Summary Background Data: The use of segmental colectomy in patients with endoscopically unresectable colonic lesions results in significant morbidity and mortality. CAL-WR is an alternative procedure that may reduce morbidity.

Single-cell derived tumor organoids display diversity in HLA class I peptide presentation.

Tumor heterogeneity is a major cause of therapeutic resistance. Immunotherapy may exploit alternative vulnerabilities of drug-resistant cells, where tumor-specific human leukocyte antigen (HLA) peptide ligands are promising leads to invoke targeted anti-tumor responses. Here, we investigate the variability in HLA class I peptide presentation between different clonal cells of the same colorectal cancer patient, using an organoid system.

Phenolisation of the Sinus Tract in Recurrent Sacrococcygeal Pilonidal Sinus Disease: A Prospective Cohort Study.

Purpose Phenolisation is a minimally invasive treatment option in patients with primary pilonidal disease. However, most studies focus on patients with primary pilonidal sinus disease, while data of patients with recurrent pilonidal disease are very scarce. The purpose of this study was to evaluate phenolisation of the sinus tract in patients with recurrent pilonidal sinus disease after previous surgery for SPSD.

Sexual Function in Patients Suffering from Sacrococcygeal Pilonidal Sinus Disease.

Introduction Sexual function is one of the aspects upon which quality of life (QoL) is based. Although previous studies have evaluated the influence of sacrococcygeal pilonidal sinus disease (SPSD) on QoL, no data are available on the influence of SPSD on sexual function in a highly active sexual population based on the age range. The aim of this prospective study was to evaluate whether SPSD has a negative impact on sexual function and whether this is influenced by the surgical treatment of SPSD.

Short-term outcomes of radical excision vs. phenolisation of the sinus tract in primary sacrococcygeal pilonidal sinus disease: a randomized-controlled trial.

Background: Phenolisation of Sacrococcygeal pilonidal sinus disease (SPSD) seems to have advantages over radical excision; however, a randomized-controlled trial (RCT) comparing both techniques is lacking. The aim of our study was to compare sinus pit excision and phenolisation of the sinus tract with radical excision in SPSD in terms of return to normal daily activities.

Methods: This study was a single-center RCT.

[Chronic pilonidal sinus disease: overview of treatment options].

Chronic pilonidal sinus disease: overview of treatment options Pilonidal sinus disease is a common disease in predominantly young men; this condition can have a significant socio-economic impact. Although excision with primary or secondary wound healing is often applied, there is no consensus on the treatment of first choice for pilonidal sinus disease. Minimally invasive techniques, such as phenolisation, laser, and endoscopic treatments are increasingly applied, since these are associated with less pain, faster wound healing and facilitating a more rapid return to work for patients.

Intra-tumour diversification in colorectal cancer at the single-cell level.

Every cancer originates from a single cell. During expansion of the neoplastic cell population, individual cells acquire genetic and phenotypic differences from each other. Here, to investigate the nature and extent of intra-tumour diversification, we characterized organoids derived from multiple single cells from three colorectal cancers as well as from adjacent normal intestinal crypts.

The effect of hair removal after surgery for sacrococcygeal pilonidal sinus disease: a systematic review of the literature.

Background: It has been suggested that removal of body hair in the sacrococcygeal area prevents recurrence after surgery for sacrococcygeal pilonidal sinus disease (SPSD). The aim of this study was to review the literature regarding the effect of hair depilation on the recurrence rate in patients surgically treated for SPSD.

Methods: A systematic search was performed in PubMed, EMBASE, and The Cochrane Library by using synonyms for SPSD.

Long-term Results of a Randomized Double-blinded Prospective Trial of a Lightweight (Ultrapro) Versus a Heavyweight Mesh (Prolene) in Laparoscopic Total Extraperitoneal Inguinal Hernia Repair (TULP-trial).

Objective: The aim of the randomized clinical trial was to compare the 2 years of clinical outcomes of a lightweight (Ultrapro) vs a heavyweight (Prolene) mesh for laparoscopic total extraperitoneal (TEP) inguinal hernia repair.

Background: Lightweight meshes reduce postoperative pain and stiffness in open anterior inguinal hernia repair. The discussion about a similar benefit for laparoscopic repair is ongoing, but concerns exist about higher recurrence rates.

Enterobius vermicularis infection of the liver in a patient with colorectal carcinoma with suspected liver metastasis.

A 68-year-old man diagnosed with cT3N2 adenocarcinoma of the rectum presented with a synchronous solitary liver metastasis on CT scan. Neoadjuvant chemoradiotherapy was started to downstage the primary tumour. Resection of the rectal tumour followed 3 months after the last radiotherapy session and primary resection of the isolated liver lesion was performed in the intervening period.

Local administration of gentamicin collagen sponge in surgical excision of sacrococcygeal pilonidal sinus disease: a systematic review and meta-analysis of the literature.

Surgical site infections occur in up to 24 % of patients after surgical excision of sacrococcygeal pilonidal sinus disease with primary wound closure. Local administration of antibiotics by a gentamicin collagen sponge could reduce this infection rate. The objective of this systematic review and meta-analysis was to evaluate the effect of a gentamicin collagen sponge on outcome after surgical excision in patients with sacrococcygeal pilonidal sinus disease.

Combined surgery for primary colorectal cancer and synchronous pulmonary metastasis: a pilot experience in two patients.

Background: Pulmonary metastasectomy in patients with pulmonary metastases from primary colorectal cancer seems to improve survival in properly selected patients. Therefore, pulmonary metastasectomy has been incorporated widely into the management of colorectal pulmonary metastases. Generally, in patients presenting with primary colorectal cancer and synchronous pulmonary metastases, the primary colorectal cancer is resected first, followed by pulmonary metastasectomy during a second-stage procedure.

Pit excision with phenolisation of the sinus tract versus radical excision in sacrococcygeal pilonidal sinus disease: study protocol for a single centre randomized controlled trial.

Background: Excision of the pit of the sinus with phenolisation of the sinus tract and surgical excision are two treatment modalities for patients with sacrococcygeal pilonidal sinus disease. Phenolisation seems to have advantages over local sinus excision as it is performed under local anaesthesia with a relatively small surgical procedure, less postoperative pain, minor risk of surgical site infection (8.7%), and only a few days being unable to perform normal activity (mean of 2.

Multidisciplinary decision-making on chemotherapy for colorectal cancer: an age-based comparison.

Introduction: With the ageing of society, optimising decision-making for older patients with cancer becomes increasingly important. A first step is awareness of current clinical practice. We analysed how treatment decisions regarding chemotherapy for older and younger patients with colorectal cancer are currently being made by the multidisciplinary team, the oncologist and the patient.

Three-month results of the effect of Ultrapro or Prolene mesh on post-operative pain and well-being following endoscopic totally extraperitoneal hernia repair (TULP trial).

Background: Recurrence rates after inguinal hernia repair have been reduced to a few per cent, since mesh repair has become standard of care. Lightweight meshes reduce post-operative pain and stiffness in open anterior repair, but for endoscopic repair, the discussion about this benefit is ongoing. This study was done to analyse the effects of lightweight mesh versus heavyweight mesh following endoscopic totally extraperitoneal (TEP) hernia repair.

Is there an end of the "learning curve" of endoscopic totally extraperitoneal (TEP) hernia repair?

Background: An important challenge of totally extraperitoneal (TEP) hernia repair is the learning curve. The European guidelines suggest that the learning curve ranges between 50 and 100 procedures, with the first 30-50 being critical. Others suggest that optimal outcomes are achieved after 200 or more TEP procedures.

The effect of ultrapro or prolene mesh on postoperative pain and well-being following endoscopic Totally Extraperitoneal (TEP) hernia repair (TULP): study protocol for a randomized controlled trial.

Background: The purpose of this study was to describe the rationale and design of a randomized controlled trial analyzing the effects of mesh type (Ultrapro versus Prolene mesh) on postoperative pain and well-being following an endoscopic Totally Extraperitoneal (TEP) repair for inguinal hernias (short: TULP trial).

Methods And Design: The TULP trial is a prospective, two arm, double blind, randomized controlled trial to assess chronic postoperative pain and quality of life following implantation of a lightweight (Ultrapro) and heavyweight (Prolene) mesh in endoscopic TEP hernia repair. The setting is a high-volume single center hospital, specializing in TEP hernia repair.
