IntroductionMesh placement is the main standard in repair of inguinal hernia, and laparoscopic repair is the standard of care via spinal, epidural, or combined anesthesia. Here, we compared open and laparoscopic total extraperitoneal (TEP) repairs under general (GA) and spinal anesthesia (SA).MethodsInguinal hernia patients (n=440) were analyzed retrospectively. There were four groups: Group 1 was TEP under GA (TEP-GA) (n=111); Group 2 was open mesh repair (OM) under SA (n=116) (OM-SA); Group 3 was open mesh repair under GA (n=117) (OM-GA); Group four was TEP under SA (n=96) (TEP-SA). The age, body mass index, duration of operation, hospital stay, postoperative Visual Analog Scale scores, recurrence, postoperative pain, urinary retention, headache, and patient satisfaction were all recorded.ResultsThere was no significant difference in terms of hypotension, vomiting, seroma and scrotal edema, recurrence, and wound infection incidence between the groups. However, the operation duration, hospital stay period, headache, urinary retention, postoperative Visual Analog Scale scores, chronic pain, and patient satisfaction showed significant differences between groups.ConclusionLaparoscopic TEP hernia repair is a safe and effective method along with its advantages of shorter hospital stay, less recurrence, less postoperative pain, higher patient satisfaction, and similar postoperative complication rates. SA has the disadvantage of higher incidence of headache and urinary retention compared to GA.

Although some authors report inferior outcomes of vascular access procedures in diabetic patients, there is evidence that most of the problems encountered can be dealt with by careful patient selection, surgical skill, and experience.

Introduction: Transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP) hernia repair are the two most commonly used techniques in laparoscopic inguinal hernia repair, and the results of comparative studies are conflicting. The objective of this study is to compare the two methods in unilateral inguinal hernia repair. Materials and Methods: The data of consecutive patients who underwent TEP and TAPP due to unilateral inguinal hernia between December 7, 2017, and March 15, 2020, were analyzed retrospectively. The primary outcome was to compare the clinical outcomes of the two techniques in terms of complications, conversion, pain, and operative time. The secondary outcome was recurrence rates. Results: A total of 301 (TEP n=234, TAPP n=67) patients were included in the study. The mean age was 43 years, and the follow-up period was two years. The groups were similar in terms of demographic characteristics and hernia type. The mean operative time was longer in the TAPP group than in the TEP group (67 min and 58 min, p=0.007). The recurrence rate was 4.3% in the TEP group and 5.9% in the TAPP group (p>0.05). The conversion rate was 6% in both groups. In total, 19 (6.3%) patients had intraoperative complications (TEP n=16, TAPP n=3), and 23 (7.6%) patients had postoperative complications (TEP n=16, TAPP n=7). Both intraoperative and postoperative complication rates were similar between the groups (p=0.31 and p=0.051, respectively). The early postoperative pain was less in the TEP group (p=0.004). Conclusion: Less early postoperative pain and shorter operative time were detected in patients who underwent TEP.

Inguinal and incisional hernias are the two most common types of hernias caused by abdominal wall weakness and defects in connective tissue. The structure of the extracellular matrix, mainly collagen and metalloproteinases (MMPs), and their regulators have been studied extensively and found to play a significant role in the pathophysiology of hernias. One of the regulators of MMPs, tissue inhibitor metalloproteinases (TIMPs), bind to MMPs and inhibit

BACKGROUND: The location of colonic tumors has been linked to different clinical and oncologic outcomes. Transverse colon cancers are generally included as right colon cancers. Furthermore, hepatic and splenic flexure tumors are usually included as components of the transverse colon. OBJECTIVE: This study was aimed at comparing the clinicopathologic characteristics and long-term outcomes between mid-transverse and right and left colon cancers and determining the prognostic impact of the primary tumor location in the mid-transverse colon. DESIGN: This was a retrospective study. SETTINGS: Two specialized colorectal centers were included. PATIENTS: Patients who underwent curative surgery for colon cancer were analyzed. Tumors located in the transverse colon, excluding the flexures, were defined as mid-transverse colon cancers. MAIN OUTCOME MEASURES: Demographic characteristics, operative outcomes, pathologic results, and long-term outcomes were the primary outcome measures. RESULTS: Of the 487 patients, 41 (8.4%) had mid-transverse, 191 (39.2%) had right, and 255 (52.4%) had left colon cancers. For mid-transverse colon cancers, the mean length of hospital stay, mean length of the resected specimen, and the mean number of harvested lymph nodes were significantly higher. For patients with stage I to III cancer, the 5-year overall and disease-free survival rates were significantly worse in the mid-transverse colon cancers than in the right and left colon cancers (overall survival: 55.5% vs 82.8% vs 85.9%, p = 0.004, and disease-free survival; 47.7% vs 72.4% vs 79.5%, p = 0.003). After adjustment for other clinicopathologic factors, mid-transverse colon cancers were significantly associated with a poor prognosis (HR = 2.19 [95% CI, 1.25–3.83]; p = 0.006). LIMITATIONS: Molecular and genetic information were unavailable in this retrospective study. CONCLUSIONS: In our case series, colon cancers located in the mid-transverse colon showed poorer prognosis than cancers in other locations. The impact of tumor location in the mid-transverse colon on prognosis, including molecular and genetic markers, should be investigated further in prospective studies.

ANTECEDENTES: La ubicación de los tumores de colon se ha relacionado con diferentes resultados clínicos y oncológicos. Los cánceres de colon transverso se incluyen generalmente como cánceres de colon derecho. Además, los tumores del ángulo hepático y esplénico suelen incluirse como un componente del colon transverso.
