Laparoscopic organ-preserving gastric resection improves the quality of life in stromal tumor patients An observational study with 23 patients.

AIM: The aim of this study is to investigate whether organ preserving gastrectomy (OPG) would yield a greater ability to save more tissue and functions of the stomach and eventually provide better quality of postoperative life (QoPL) for patients with primary gastric gastroinstestinal stromal tumor (PG-GIST). MATERIAL AND METHODS: A retrospective analysis of 23 consecutive patients with PG-GIST who underwent laparoscopic conventional surgery and OPG from June 2008 to December 2016 was performed. Gastrointestinal quality of life index (GIQLI), the area of tumor-free tissue (TFT), body mass index, and postoperative complications were recorded. RESULTS: Both first- and sixth-month GIQLI scores (mean = 105.4 ± 9.5 and 117.0 ± 11.1, respectively) were significantly higher than baseline scores (mean = 100.9 ± 10.2) of the study population (z = -3.32 and -3.86, p = 0.001 and 0.0001, respectively). GIQLI scores were inversely related to TFT area (r = -0.635, p = 0.001). Linear regression analysis revealed 0.130 decrease in GIQLI scores at 6 months each cm2 of removed TFT area. CONCLUSION: Laparoscopic OPG seems to be useful in terms of oncologic safety, minimizing the excessive resection of TFT and maximizing the gastric remnant, thereby improving the QoPL of the patients.

The clinical characteristics and surgical approach of scar endometriosis: A case series of 14 women.

Scar endometriosis, also referred to as abdominal wall endometriosis (AWE), is a rare form of endometriosis that usually develops in the scar after obstetric or gynecological surgeries, including cesarean section (CS). Recently, the occurrence of scar endometriosis has been increasing together with the increase of CS incidence. Scar endometriosis can be clinically misdiagnosed as hernia, lipoma, or hematoma. Here we retrospectively analyzed the clinical aspects of scar endometriosis and surgical approach in 14 patients from a tertiary hospital, who were treated by surgery, between 2012 and 2017. The mean age was 32.71 ± 8.61 years (range: 19-45). Palpable mass and cyclic pain at the scar site were the most common complaints. Twelve patients had previously undergone CS, and two patients had undergone a surgery of ovarian endometrioma. The preoperative diagnosis was determined with ultrasonography (US), magnetic resonance imaging (MRI), or computed tomography (CT). Preoperatively, scar endometriosis was diagnosed in 12/14 patients (85.7%), while 2 patients (14.3%) were diagnosed with inguinal hernia. The treatment was surgical excision in all patients; in addition, mesh repair surgery was performed in 1 patient with recurrent scar endometriosis. Postoperatively, endometriosis was confirmed by histology in all patients. The average size of endometriomas was 24.71 ± 6.67 mm (range: 11-35). No woman had concurrent pelvic endometriosis. In the follow-up period (mean: 9 months) the recurrence of endometriosis was not observed. Scar endometriosis should be considered in all women of reproductive age presenting with cyclic pain and swelling in their abdominal incision sites.

Incidental gallbladder cancer at cholecystectomy.

BACKGROUND: Gallbladder tumours rank fifth in the world among gastrointestinal system tumours. Coincidental gallbladder tumours are diagnosed during cholecystectomies, or by examining the cholecystectomy material. AIMS: In this study, we aimed to evaluate the incidence of gallbladder cancer among patients undergoing cholecystectomies due to gallbladder disease. STUDY DESIGN: Retrospective study METHODS: The files of 341 patients who had undergone routine cholecystectomy operations between January 2013 and March 2016 were reviewed, and their pathology results were recorded. Those patients with gallbladder carcinomas were evaluated in terms of age, gender, preoperative findings, existing symptoms, radiological findings, surgical findings and follow-up. The cancer invasion depth was classified according to the American Joint Commission on Cancer (AJCC) atlas, and this study was approved by the ethical committee of our university. RESULTS: Among the 341 patients who participated in this study, 253 (74.41%) were female, 88 (25.80%) were male, and their average age was 49.61 years old (17-86). Seven of the patients (2.05%) had gallbladder tumours; six of which were female, one was male and their average age was 67.71 years old (62-76). One tumour was diagnosed as a frozen specimen during the operation, while the others were diagnosed during the postoperation phase. Three of the patients had T1b and four had T2 tumours. CONCLUSION: Gallbladder tumours detected incidentally could extend survival rates with proper surgical intervention and chemotherapy. The possibility of a tumour should not be dismissed in those patients with advanced age, females or patients with gallbladder stones. Frozen specimens should be created during a cholecystectomy, and if there is any doubt about the diagnosis, a postoperative histopathological examination of the gallbladder should be conducted. KEY WORDS: Cholecystectomy, Gall bladder stone, Incidental gallbladder carcinoma.

Conservative vs Surgical Interventions for Umbilical Pilonidal Sinus: A Multicenter, Double-Blind, Prospective, Randomized Clinical Trial.

BACKGROUND: Umbilical pilonidal sinus (UPS) is one of the most neglected disorders, and there is still no clear consensus regarding optimal treatment of the disease. We therefore present our data from a prospective, randomized, controlled clinical trial comparing conservative vs surgical treatment of UPS. STUDY DESIGN: The study was conducted in Turkey between January 2012 and November 2015. All eligible patients with the diagnosis of UPS (n = 84) were randomized for either conservative treatment (CT, n = 42) or surgical treatment (ST, n = 42). All patients were followed up for at least 2 years; then, the results of both groups were compared. The primary outcomes were initial healing, recurrence, and the cure rate of the disease after each treatment modality. RESULTS: Mean (± SD) age of the patients was 20.83 ± 5.73 years old, and the majority were men (94%). Nearly 60% of the patients had a deep navel, and 55% had intense hair status. The main symptoms were drainage and wetness, pain, itching, and malodor. Overall, in 10 (27.8%) patients, relapse of the disease was observed in the CT group; it was observed in only 1 patient in the ST group (p = 0.002). Initial healing time was significantly shorter in the ST group (p = 0.001). Of the 81 patients who completed the 2-year follow-up, a cure could be obtained in only 28 of 41 patients in the CT group; it was achieved in all 40 patients in the ST group (68.3% vs 100%, respectively; p = 0.0001). CONCLUSIONS: This study provided evidence that surgical treatment is superior to conservative surgery regarding the primary and secondary outcomes of UPS at least 2 years after surgery.

Colonoscopy without sedation.

BACKGROUND/AIMS: In Turkey, colonoscopy is a procedure generally performed with intravenous sedation and analgesia. Most of the complications of colonoscopy are related to sedation. The aims of this study were to determine the percentage of patients who could successfully undergo nonsedated colonoscopy without sedation and to assess patient tolerance and acceptance. METHODS: The study included 120 consecutive patients undergoing colonoscopy by two endoscopists in our endoscopy unit. The procedure routinely began without sedation, which was later given (midazolam and hyoscine butylbromide) only if significant discomfort occurred. Parameters of blood pressure, oxygen saturation and heart rate were measured before and during colonoscopy. After the procedure patients were asked to rate their pain on a four point scale 1=no pain, 2=slight, 3=moderate, 4=severe and they were also asked if they would be willing to undergo colonoscopy again without sedation. RESULTS: Eighty eight percent of all colonoscopies were completed without sedation. Mean PaO2 was 96.46 in nonsedated patients and 93.90 (significant p<0.05) in sedated patients. No difference was found between blood pressure and pulse rate of nonsedated and sedated patients. The mean pain score was 2.0 for the nonsedated patients and 3.8 (significant p<0.05) for the sedated patients. Eighty eight percent of patients stated that they would be willing to undergo colonoscopy without sedation again. CONCLUSIONS: In experienced hands, colonoscopy without sedation can be completed successfully in most patients, without any complications and use of extra instrumentation.
