The impact of the Covid 19 pandemic in colorectal cancer.

AIM: COVID-19 was first seen in China at the end of December 2019. The disease spread rapidly and was declared as a pandemic by the World Health Organization (WHO) on March 11, 2020. Only urgent surgi cal cases and oncological surgeries that cannot be postponed were performed during this pandemic process. As a wasting disease, colorectal cancer (CRC) itself and its corresponding treatment may weaken the immune response to respiratory bacteria, makes patients more susceptible to virus infection. Besides, colorectal cancer patients are immunosuppressed because of the side effects of chemotherapy and/or radiotherapy taken. The choice of surgical procedures and perioperative management of the patients with CRC has become even more important in the COVID-19 pandemic. The impact on CRC surgery is unknown. In this study, we aimed to evaluate the effects of the COVID-19 pandemic on the preopartive, intraoperative, and postoperative findings of patients operated for colorectal cancer in our clinic. MATERIAL-METHOD: We defined the 'COVID-19' period as occurring between 12-03-2020 and 31-08-2020. All the enrolled patients were divided into two groups, pre-COVID-19 group (Pre-CG; 66 cases) and COVID-19 group (CG; 43 cases). A total of 109 patients with CRC were included in this study. Patient characteristics, preoperative, intraoperative, and postoperative clinicopathological findings were compared between groups. RESULTS: The waiting times before admission increased in CG (Pre-CG [5.34±2.55] vs CG [18.13±9.11]; p<0.001). After admission, the waiting time before surgery was longer in CG (Pre-CG [2.04±1.34] vs CG [5.53±6.00]; p<0.001). There were no significant difference between the groups in terms of operation method (laparoscopic/open), operation type (emergency/elective), surgical procedure, combine organ resection, intraoperative blood transfusion requirment, operation time (p values, respectively; p=0.082; p=0.474; p=0.317; p=0.656; p=0.617; p=0.696). In this study, no significant difference was found between the groups in terms of postoperative complications (p=0.357) and mortality (p=0.826). It was found that the ICU stay was significantly shorter in CG (Pre-CG [11.63±2.22] vs CG [1.48±0.76]; p=0.008). CONCLUSIONS: In this study, it was seen that the COVID-19 pandemic did not affect morbidity and mortality in CRC surgery, but it prolonged admission waiting and operation waiting times. Since there is very little data in the literature regarding the effect of COVID-19 on CRC surgery, our study will guide future studies on this subject.

Validation of the Turkish translation of the low anterior resection syndrome (LARS) score.

BACKGROUND: Long-term bowel dysfunction after resection for rectal cancer, known as low anterior resection syndrome (LARS), is observed in many patients. The LARS score was developed to assess this syndrome and its impact on the quality of life in Danish patients. Recently versions in English and many other languages have been validated. The aim of this study was to validate the Turkish translation of the LARS score in patients who have undergone treatment for rectal cancer. METHODS: Rectal cancer patients who underwent low anterior resection in May 2000- May 2018 in three Turkish centers received the LARS score questionnaire, the European Organisation for Research and Treatment Of Cancer Core Quality of Life questionnaire [Ed.11] (EORTC QLQ-C30), and a single ad hoc quality of life question. The test-retest reliability of the LARS score was evaluated by asking a randomly selected subgroup of patients to repeat the assessment of the LARS score 2 to 4 weeks after their initial response. RESULTS: A total of 326 patients were reviewed and contacted for the study, and 222 (68%) were eligible for the analyses (129 males, 93 females, median age 64 years [range:24-87 years, IQR = 14]) There was a strong association between the LARS score and quality of life (p < 0.01) and the test-retest reliability was high. The intraclass correlation coefficient was 0.78 (95% CI 0.73-0.83) for the whole study group and 0.79 (95% CI 0.68-0.87) for the subgroup, indicating strong reliability. CONCLUSIONS: The Turkish translation of the LARS score has psychometric properties comparable with previously published results in similar studies. The Turkish version of the LARS score can be considered a valid and reliable tool for measuring LARS in Turkish rectal cancer patients. CLINICAL TRIAL REGISTRATION: NCT05289531.

Perception of COVID-19 Pandemic Among IBD Clinicians and IBD Surgeons in Black Sea Region: A Cross-Sectional Questionnaire Study.

BACKGROUND: Since December 2019, the COVID-19 pandemic has created an increasing challenge in managing inflammatory bowel dis- ease patients both medically and surgically. Although several international and national medical/surgical associations published guide- lines in this area, there is still a huge difference between daily practices and these guidelines, especially depending on regional practices and governmental policies. Therefore, we aimed to investigate and define gastroenterologists' and surgeons' fear of COVID-19 and how they have managed inflammatory bowel disease patients during this pandemic in the Black Sea region. METHODS: A 20-question survey was administered to 70 gastroenterology specialists and 80 general surgeons who are mainly focused on the management of inflammatory bowel disease in 5 countries in the Black Sea region. RESULTS: The majority of respondents (81.3%) mentioned that they have concerns that their inflammatory bowel disease patients were at risk of contracting COVID-19. In addition, the majority of respondents (80.3%) believed that inflammatory bowel disease itself, inde- pendent of medications, might increase the risk of contracting COVID-19. The majority of gastroenterologists told that they did not stop inflammatory bowel disease medications due to the COVID-19 pandemic unless patients had COVID-19 disease. Surgeons overwhelm- ingly reached a consensus on how to test patients for COVID-19 perioperatively and came to a conclusion on which of the patients can- not wait to be operated. Both gastroenterologists and general surgeons, usually have similar perceptions. CONCLUSION: Despite the increasing number of definitive studies, it seems that there are still regional differences in the perception of COVID-19 and inflammatory bowel disease patient care during the pandemic.

Most cited 100 articles from Turkey on abdominal wall hernias: a bibliometric study.

OBJECTIVES: The aim of the present study was to search the most-cited articles from Turkey on abdominal wall hernias and analyze their characteristics with several parameters. MATERIAL AND METHODS: In March 2019, a search was conducted through all databases in the Web of Science (WoS) to determine the most-cited articles on abdominal wall hernias. Each article was evaluated in regard to host journal, year of publication, the complete list of authors, the type of article, main subject of the study, institution of the study group. Citation counts in Google Scholar (GSch) were also obtained. RESULTS: Mean number of citations of the top 100 articles in herniology was 30.50. Articles were published in 38 journals; Hernia is the leading host. No correlation was observed between the journal impact factors and the number of the citations. Two thirds of the articles were clinical studies. Article types had no significant effect on the citation counts. Inguinal hernia was the most frequent topic by taking place in 58 papers. Articles related to incisional hernias had a higher mean number of citations in comparison with other topics. Ankara University School of Medicine had most cited articles, the highest number of total citations, and the highest citation per articles. Ankara Numune Training and Research Hospital and Istanbul University School of Medicine had the highest number of the articles in the list. CONCLUSION: Citation counts of hernia related articles from Turkey are relatively low. Hernia is the leading journal for Turkish studies. Inguinal hernia is the most frequent topic whereas papers about incisional hernias receive more citations than others.

Surgical Drains After Laparoscopic Donor Nephrectomy: Needed or Not?

BACKGROUND Routine placement of prophylactic drains after laparoscopic donor nephrectomy has been suggested and has become common practice in some centers. However, there is a lack of evidence proving the surgical benefits of routine drain placement in laparoscopic donor nephrectomy. Here, we assessed the effect of surgical drain placement on recovery, length of hospital stay, and complication rates of live kidney donors. MATERIAL AND METHODS This retrospective study included all live donor nephrectomies performed at a single institution from January 2010 to January 2017. Surgeries were performed by 2 surgeons; one routinely placed a closed suction drain after LDN whereas the other did not. Patients operated on by these 2 surgeons were enrolled in either the drain or no drain group. Demographic data, preoperative and postoperative creatinine levels, estimated blood loss (EBL), surgical time, surgical complications, and length of hospital stay were compared. RESULTS The study included 272 patients. Three were converted to open donor nephrectomy and were excluded (1.1%). Among the 269 patients, 156 (57.9%) had surgical drains and 113 (42.1%) did not. Mean surgical time, estimated blood loss, and duration of hospital stay did not significantly differ between groups. Postoperative complications were encountered in 17 of the patients, but the overall complication rate did not differ between patients with vs. those without surgical drains. CONCLUSIONS There was no significant difference between the drain and no drain groups in terms of length of hospital stay, complication rates, or postoperative creatinine levels. Thus, placement of a surgical drain in the setting of an LDN is not justified based on our single-center experience.

Endoscopic Pilonidal Sinus Treatment Combined With Crystalized Phenol Application May Prevent Recurrence.

BACKGROUND: No single treatment yet exists for pilonidal disease that has a short healing time, good cosmetic results, and a low rate of recurrence. Phenol crystal application and diathermy ablation through an endoscope have been used for the treatment of pilonidal disease, but this cohort is the first one to combine them. OBJECTIVE: The purpose of this study was to examine the safety, effectiveness, and short- and long-term outcomes of crystalized phenol treatment combined with endoscopic pilonidal sinus treatment for pilonidal disease. DESIGN: This was a prospective cohort study. SETTINGS: Procedures were performed in 2 hospitals by the same surgeon between February and July 2014. PATIENTS: Twenty-three patients underwent surgical treatment for pilonidal disease. INTERVENTIONS: Under local anesthesia and sedation, all of the patients underwent a video-assisted diathermy ablation of the sinus cavity and the application of phenol crystals. MAIN OUTCOME MEASURES: Adverse events were recorded as a measure of safety and tolerability. Failure to heal and recurrence rate were documented and evaluated. RESULTS: Patients were discharged on the same day as surgery. There was no or minimal postoperative pain (mean visual analog scale score, 1.40 ± 0.95). Mean operation time was 20.43 ± 6.19 minutes, and the median return-to-work duration was 2.00 days (mean, 3.03 ± 2.95 d). Patients were followed-up for 18 to 24 months (mean, 22.00 ± 1.88 mo). No serious complications or rehospitalization were observed. No primary failure to heal or recurrence was observed. LIMITATIONS: This study did not include a control group with which to compare and consisted of a relatively small number of patients. CONCLUSIONS: Crystalized phenol treatment combined with endoscopic pilonidal sinus treatment was safe, tolerable, and achieved fast and durable healing with no recurrence over an average of 22 months of follow-up.

Laparoscopic revision surgery for gastroesophageal reflux disease.

Laparoscopic antireflux surgery is a frequently performed procedure for the treatment of gastroesophageal reflux in surgical clinics. Reflux can recur in between 3% and 30% of patients on whom antireflux surgery has been performed, and so revision surgery can be required due to recurrent symptoms or dysphagia in approximately 3% to 6% of the patients. The objective of this study is to evaluate the mechanism of recurrences after antireflux surgery and to share our results after revision surgery in recurrent cases.From 2001 to 2014, revision surgery was performed on 43 patients (31 men, 12 women) between the ages of 24 and 70 years. The technical details of the first operation, recurrence symptoms, endoscopy, and manometry findings were evaluated. The findings of revision surgery, surgical techniques, morbidity rates, length of hospitalization, and follow-up period were also recorded and evaluated.The first operation was Nissen fundoplication in 34 patients and Toupet fundoplication in 9 patients. Mesh hiatoplasty was performed for enforcement in 18 (41.9%) of these patients. The period between the first operation and the revision surgery ranged from 4 days to 60 months. The most common finding was slipped fundoplication and presence of hiatal hernia during revision surgery. Revision fundoplication and hernia repair with mesh reinforcement were used in 33 patients. The other techniques were Collis gastroplasty, revision fundoplication, and hernia repair without mesh. The range of follow-up period was from 2 to 134 months. Recurrence occurred in 3 patients after revision surgery (6.9%). Although revision surgery is difficult and it has higher morbidity, it can be performed effectively and safely in experienced centers.

Video-assisted treatment of pilonidal disease, using a combination of diathermy ablation and phenol application.

Video-assisted diathermy ablation (VADA) and crystallised phenol application (CPA) have been independently suggested as minimally invasive treatment options for sacrococcygeal pilonidal disease (SPD). The failure rates may be 5-33% with either method, and these methods have a longer healing time when used alone. Thus, we combined the two methods to fulgurate the infected inner lining of the sinus after cleaning up the hair and debris, and to identify the anatomy of the pilonidal cavity in its entirety, including its branches and cavities, by video assistance; the ultimate aim was to disperse sclerosing phenol crystals for faster healing and potentially less or no recurrence. This is the first case in the literature that has been treated by combining CPA and VADA. The patient healed within less than a month, with no need for professional wound care, and was free of recurrence at 2-year follow-up.

Breast hamartoma: a clinicopathologic analysis of 27 cases and a literature review.

OBJECTIVES: Breast hamartoma is an uncommon breast tumor that accounts for approximately 4.8% of all benign breast masses. The pathogenesis is still poorly understood and breast hamartoma is not a well-known disorder, so its diagnosis is underestimated by clinicians and pathologists. This study was designed to present our experience with breast hamartoma, along with a literature review. METHOD: We reviewed the demographic data, pathologic analyses and imaging and results of patients diagnosed with breast hamartoma between December 2003 and September 2013. RESULTS: In total, 27 cases of breast hamartoma operated in the Ankara University Medicine Faculty's Department of General Surgery were included in the study. All patients were female and the mean age was 41.8±10.8 years. The mean tumor size was 3.9±2.7 cm. Breast ultrasound was performed on all patients before surgery. The most common additional lesion was epithelial hyperplasia (22.2%). Furthermore, lobular carcinoma in situ was identified in one case and invasive ductal carcinoma was observed in another case. Immunohistochemical staining revealed myoid hamartoma in one case (3.7%). CONCLUSION: Breast hamartomas are rare benign lesions that may be underdiagnosed because of the categorization of hamartomas as fibroadenomas by pathologists. Pathologic examinations can show variability from one case to another. Thus, the true incidence may be higher than the literature indicates.

The therapeutic results after laparoscopic hellers' myotomy and partial fundoplication for achalasia.

BACKGROUND/AIMS: The aim of this prospectively designed study was to postoperatively assess the subjective complaints or relief of symptoms of achalasia patients' who underwent Laparoscopic Hellers' myotomy and partial fundoplication in our clinic. MATERIALS AND METHODS: 40 patients were enrolled in the study that underwent Laparoscopic Hellers' myotomy and partial fundoplication (toupet or dor) for idiopathic achalasia in our clinic between years 2002 and 2012. Postoperative follow-up was conducted at 1st, 3rd. and 6th months in each patient for symptoms and a follow-up questionnaire was completed which is classified according to Vantrappen and Hellemans' modified classification. RESULTS: 34 patients underwent Laparoscopic Heller myotomy with Toupet fundoplication whereas 6 patients underwent Laparoscopic Heller myotomy with Dor fundoplication. After 3 months, 2 patients' complaints of dysphagia were detected (5%). In the 6 month follow-up, one of these two patient dysphagia symptoms got worsened and a balloon dilatation was performed (2.5%). In the other one no clinical reason was found for dysphagia and medical therapy was initiated. In the 6 th month only three patients (7.5%) were presented with gastroesophageal reflux which successful medical treatment was initiated. CONCLUSION: Laparoscopic myotomy with fundoplication seems to be the most effective surgical technique that provides both short and long term symptomatic relief with released hospitalization time and less complication rate.

Unroofing and curettage for the treatment of acute and chronic pilonidal disease.

BACKGROUND: Various surgical techniques are available in the management of pilonidal sinus, but controversy concerning the optimal surgical approach persists. The present study analyzes the outcome of unroofing and curettage as the primary intervention for acute and chronic pilonidal disease. METHODS: A total of 297 consecutive patients presenting with chronic disease, acute abscess, or recurrent disease were treated with unroofing and curettage. The wound was left open to heal by secondary intention. Hospitalization, time required to resume daily activities and return to work, healing time, and recurrence rates were recorded. RESULTS: All patients were discharged within the first 24 h after operation. The median period before returning to work was 3.2 +/- 1.2 days, and the mean time for wound healing was 5.4 +/- 1.1 weeks. Six patients were readmitted with recurrence of the disease within the first six postoperative months. All recurrences were in patients who did not follow the wound care advice and who did not come to regular weekly appointments. Patients with recurrence underwent repeat surgery by the same technique with good results. CONCLUSIONS: Unroofing and curettage for pilonidal sinus disease is an easy and effective technique. The vast majority of the patients, including those with abscess as well as those with chronic disease, will heal with this simple procedure, after which even recurrences can be managed successfully with the same procedure. Relying on these results, we advocate unroofing and curettage as the procedure of choice in the management of pilonidal disease.
