Effects of totally extraperitoneal and lichtenstein hernia repair on men's sexual function and quality of life.

BACKGROUND: In the literature, there have been scant studies that compare the effects of totally extraperitoneal (TEP) and Lichtenstein hernia (LH) repairs on men's sexual function and quality of life. Our aim in this study was to study the sexual function of men after TEP and LH repair according to SF 36 (Health Survey Scoring Demonstration) and IIEF (The International Index of Erectile Function). METHODS: A total of 176 men with unilateral inguinal hernia were randomized into two groups. Group T (n = 88) received TEP hernia repair, and Group L (n:88) received LH repair. Patients' demographics and perioperative findings were recorded. For all patients, the preoperative as well as postoperative 7th, 30th and 90th day SF 36 and IIEF were recorded. RESULTS: A total of 176 operations consisting of 88 TEP and 88 LH repairs were evaluated. There were no differences in demographics, hernia type, and complications except for body mass index (BMI). The operative time was higher in Group T (29.6 ± 5.8 vs. 43.5 ± 5.7 min; p = 0.001). The averages of the SF 36-Vitality and Social Function for Postoperative (PO) 30th day scores were higher in Group T. The averages of the SF 36-Bodily Pain, General Health, Physical Role, Emotional Role for PO 7-30th days SF36- Mental Health for PO 7th day and SF 36 Physical Function for PO 30-90th days scores were statistically higher in Group T. The averages of the IIEF- Erectile Function for PO 30th day, IIEF- Orgasmic Function, Sexual Desire, Intercourse Satisfaction, and Intercourse Satisfaction for PO 7th and 30th days scores were higher in Group T. CONCLUSIONS: TEP and LH repairs have similar results for recurrence, complications, and hospital stay; otherwise, TEP repair yields better results than the LH repair in the postoperative course at the 7th and 30th day evaluation, concerning sexual function and quality of life, but this benefit is no longer apparent at the 90th day. Although the short-term differences were statistically significant, they were moderate and might have a limited impact from the clinical point of view.

Is ultrasound guidance necessary to avoid complications in the implantation of venous access ports?

BACKGROUND: The aim of this study was to present demographic information of patients undergoing totally implantable venous access port (TIVAP) implantation and to investigate the rates of early and late complications, assessing the benefits of performing the procedure underUS guidance. METHODS: From May 2018 to December 2023, the outcomes of a total of 537 TIVAP implantation procedures were analyzed retrospectively. Data of the surgeons' experiences for both puncture methods (anatomical landmarks and ultrasound guidance) are presented in the study. RESULTS: The average age of the patients was 53.1±11.9 years, and 261 (48.6%) were female. The right subclavian vein was the preferred insertion site. Fourteen patients developed early complications and 11 developed late complications. Arterial puncture was the most common early complication, while catheter-related infection was the most common late complication. The age, sex, and body mass index of the patients were not independent risk factors for developing complications. Early complications increased as the number of puncture attempts did (p=0.034) and developed significantly less when ultrasound guidance was used during insertion (p=0.011). CONCLUSION: The risk of developing complications was not affected by patient's age or sex. In addition, body mass index was not shown to be an independent risk factor for patients developing complications. It may be concluded from the study that early complications in particular can be reduced with ultrasound-guided implantation.

Effect of Resection Distance from Pylorus on Weight Loss Outcomes in Laparoscopic Sleeve Gastrectomy.

BACKGROUND: Despite the established efficacy and safety of laparoscopic sleeve gastrectomy (LSG), controversy still exists on optimal operative technique, the resection distance from pylorus (DP) being among the most controversial issues. This study aimed to examine the effect of resection distance from pylorus on % excess weight loss (EWL) during postoperative period, in patients who underwent LSG for morbid obesity. METHODS: A total of 390 patients who underwent laparoscopic sleeve gastrectomy for morbid obesity were included in this retrospective study. Patients were allocated into one of the two groups based on the distance between antrum resection margin and pylorus: group A, ≤ 3 cm and group B, > 3 cm. Follow-up data for %EWS and nausea/vomiting as well as demographical and perioperative data were retrospectively reviewed and logistic regression analysis was done. RESULTS: Follow-up data up to 12 months were available for all patients, whereas 199 patients had follow-up data at 24 months. Shorter distance from pylorus was associated with higher %EWL throughout the treatment period (p < 0.001), evident from the first postoperative month (p = 0.013 for the first month, p < 0.001 for all other time points). The benefit extended up to 24 months in ≤ 3 cm group. However, nausea/vomiting was more frequent in the ≤ 3 cm group only at 1-month visit (15% vs. 4%, p < 0.001). In multivariate evaluations, while %EWL variable was taken as a dependent variable, time variable with DP × time interaction was statistically significant in the model. CONCLUSIONS: Our findings indicate that a short distance between resection margin and pylorus is associated with better and sustained %EWL in LSG. However, these patients seem to be more prone to nausea and vomiting in the early postoperative period. Further prospective large studies would help to define an optimal resection distance.

Endorectal ultrasonography versus phased-array magnetic resonance imaging for preoperative staging of rectal cancer.

AIM: To compare the diagnostic accuracy of pelvic phased-array magnetic resonance imaging (MRI) and endorectal ultrasonography (ERUS) in the preoperative staging of rectal carcinoma. METHODS: Thirty-four patients (15 males, 19 females) with ages ranging between 29 and 75 who have biopsy proven rectal tumor underwent both MRI and ERUS examinations before surgery. All patients were evaluated to determine the diagnostic accuracy of depth of transmural tumor invasion and lymph node metastases. Imaging results were correlated with histopathological findings regarded as the gold standard and both modalities were compared in terms of predicting preoperative local staging of rectal carcinoma. RESULTS: The pathological T stage of the tumors was: pT1 in 1 patient, pT2 in 9 patients, pT3 in 21 patients and pT4 in 3 patients. The pathological N stage of the tumors was: pN0 in 19 patients, pN1 in 9 patients and pN2 in 6 patients. The accuracy of T staging for MRI was 89.70% (27 out of 34). The sensitivity was 79.41% and the specificity was 93.14%. The accuracy of T staging for ERUS was 85.29% (24 out of 34). The sensitivity was 70.59% and the specificity was 90.20%. Detection of lymph node metastases using phased-array MRI gave an accuracy of 74.50% (21 out of 34). The sensitivity and specificity was found to be 61.76% and 80.88%, respectively. By using ERUS in the detection of lymph node metastases, an accuracy of 76.47% (18 out of 34) was obtained. The sensitivity and specificity were found to be 52.94% and 84.31%, respectively. CONCLUSION: ERUS and phased-array MRI are complementary methods in the accurate preoperative staging of rectal cancer. In conclusion, we can state that phased-array MRI was observed to be slightly superior in determining the depth of transmural invasion (T stage) and has same value in detecting lymph node metastases (N stage) as compared to ERUS.

Role of Laparoscopic Appendectomy Radix Ligation Techniques on the Formation of Inner Abdomen Abscess.

OBJECTIVES: Our aim was to study whether laparoscopic appendectomy radix ligation techniques were eutrophic in the development of intra-abdominal abscess. METHODS: Between September 2009 and April 2017, all emergency cases admitted to our surgery polyclinic were reviewed, and the results of the patients who underwent laparoscopic appendectomy were collected. Appendectomy radix ligation techniques were reviewed from surgical notes on discharge reports. Postoperative controls were also reviewed, and any cases with abscess formation were reported. RESULTS: A total of 350 patients were included in the study. Of these cases, 207 were males, and 143 were females. The mean age of the patients was 26.89±4.9 years. One hundred eighty-nine cases were found to have two endoloops placed on top of each other, whereas 161 cases had a 2 mm distance left in between the two endoloops and tied. None of the 189 cases who had endoloops placed on top of each other developed abscess formation. However, of the 161 cases who had endoloops with a 2 mm distance in between, 8 reported with abscess formation in the inner abdomen. Of these eight cases, seven had percutaneous abscess drainage by an interventional radiologist, whereas one was treated with relaparoscopy. CONCLUSION: In the present study, patients who had endoloops placed on top of each other developed no abscess formation, whereas in the literature's gold standard procedure, those with a 2 mm distance left between two endoloops developed an inner abdominal abscess formation in 8 (4.9%) of the patients. We believe that this 2 mm dead space distance left between the two endoloops contributes to the formation of the abscess.

The ability of phased-array MRI in preoperative staging of primary rectal cancer: correlation with histopathological results.

PURPOSE: This study evaluated the accuracy of phased-array magnetic resonance imaging (MRI) for preoperative local tumor staging in primary rectal cancer and emphasized the importance of the preoperative differentiation of T2 tumors from T3 tumors so the appropriate treatment can be applied. MATERIALS AND METHODS: Twenty-four patients with primary rectal cancer were examined preoperatively using 1.5 T MRI with a phased-array coil. Multiplanar T2-weighted images were obtained. Rectum anatomy, depth of tumor invasion, mesorectal involvement and lymph nodes were assessed. All patients underwent radical surgery. The histological sections were evaluated microscopically. The correlation of magnetic resonance imaging and histopathology was assessed using the kappa statistic. Overstaging with MRI was compared with Fischer's exact test. RESULTS: Histopathological examination of the tumors revealed adenocarcinoma. When the tumors were staged, there was one patient with a pT1 tumor, six patients with pT2 tumors, and 17 patients with pT3 tumors. Using MRI, four patients with pT2 were overstaged as T3, and one patient with pT3 was overstaged as T4. In the remaining cases (one pT1, two pT2, and 16 pT3), MRI correctly assessed the stage of transmural invasion. The accuracy of T staging and metastatic lymph node detection with MRI was calculated as 79.2% and 58.5%, respectively. CONCLUSION: Phased-array MRI is a valuable technique for the preoperative staging of rectal cancer, especially in the differentiation of T2 and T3 tumors.
