Inguinal hernia repair, according to Desarda, is a pure tissue surgical technique using external oblique fascia to reinforce the posterior wall of the inguinal canal. This has provided an impetus for the rethinking of guideline adherence toward minimally invasive and mesh-based surgery of inguinal hernia. In this study, a retrospective analysis of this technique was conducted in two German hospitals. Between 6/2013 and 12/2020, 120 operations were performed. Analysis included patient characteristics, duration of operation, length of hospital stay, and perioperative complications. Data were used to achieve a matched-pair analysis comparing Desarda to laparoscopic transabdominal preperitoneal (TAPP) hernia repair. Propensity scores were calculated based on five preoperative variables, including sex, age, American Society of Anesthesiology classification, localization, and width of the inguinal hernia in order to achieve comparability. Additionally, we assessed pain level and quality of life (QoL) 12 months postoperatively. The focus of our study was a comparison of QoL to a reference population and TAPP cohort. The study population consisted of 106 male and 14 female patients, and the median age was 37.5 years. The median operation time was 50 min, and the median length of hospital stay was 2 days. At a follow-up of 17 months, the median recurrence rate was 0.8%, and two cases of chronic postoperative pain were recorded. Postoperative QoL does not significantly differ between Desarda and TAPP. In contrast, Desarda patients had a significantly higher QoL compared with the reference population. In summary, Desarda’s procedure is a good option as a pure tissue method for inguinal hernia repair.

Background: Component separation (CS) for tension-free approximation of fascial edges is the established technique for the repair of large ventral hernias mostly regarding midline defects. Recent studies suggest lower complication rates following a modified version of this technique using a partially endoscopic-assisted approach, whereas little is known about the quality of life (QoL) in the long-term evaluation of these patients. Methods: A retrospective study and analysis of patients undergoing hernia repair using an open CS (OCS) and endoscopically assisted CS (ECS) technique, respectively, from 2011 to 2016 at the Rostock University Medical Center. Patients underwent a mesh-based sublay reinforcement following a distinct CS with closure of the linea alba. Patient characteristics, technical details, and short-term postoperative outcomes were determined by a physician chart review. A health-related QoL survey (EQ-5D) including a pain assessment was evaluated at a median of 19.5 months postoperatively. Results: Thirty-five patients had a CS: 25 OCS and 10 ECS. Perioperative variables were comparable except for the median defect size (169 cm² OCS vs. 86 cm² ECS; p < 0.05) and maximum width of hernia (25 vs. 13 cm). Hospitalization lasted 16.6 days in the OCS group and 7.9 days in the endoscopic group (p = 0.04). Wound complications occurred in 24% of OCS and 10% of ECS patients. Conclusions: Patients in the ECS group had a shorter hospital stay and less minor and major wound complications. These advantages led to a faster recovery directly affecting the QoL in the ECS group. This effect diminishes in the long-term follow-up with a positive trend towards the OCS technique.

Background: The Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity (POSSUM) weights the patient’s individual health status and the extent of the surgical procedure to estimate the probability of postoperative complications and death of general surgery patients. The variations Portsmouth-POSSUM (P-POSSUM) and colorectal POSSUM (CR-POSSUM) were developed for estimating mortality in patients with low perioperative risk and for patients with colorectal carcinoma, respectively. The aim of the present study was to evaluate the significance of POSSUM, P-POSSUM, and CR-POSSUM in two independent colorectal cancer cohorts undergoing surgery, with an emphasis on laparoscopic procedures. Methods: For each patient, an individual physiological score (PS) and operative severity score (OS) was attributed to calculate the predicted morbidity and mortality, respectively. Logistic regression analysis was used to evaluate the possible correlation between the subscores and the probability of postoperative complications and mortality. Results: The POSSUM equation significantly overpredicted postoperative morbidity, and all three scoring systems considerably overpredicted in-hospital mortality. However, the POSSUM score identified patients at risk of anastomotic leakage, sepsis, and the need for reoperation. Logistic regression analysis demonstrated a strong correlation between the subscores and the probability of postoperative complications and mortality, respectively. Conclusion: Our results suggest that the three scoring systems are too imprecise for the estimation of perioperative complications and mortality of patients undergoing colorectal surgery in the present day. Since the subscores proved valid, a revision of the scoring systems could increase their reliability in the clinical setting.

Complex surgery of abdominal wall hernia continues to bear the major concern of wound healing disorders. Technical modifications have not been able to sufficiently prevent wound healing impairments or infections, even in clean elective cases, especially when dealing with large‐scale hernia defects. Incisional negative pressure wound therapy (iNPWT) in its intentional use as a preventive tool has recently found its way from theoretical and experimental advantages to the clinical routine. Different indications have been defined but evidence is lacking. We performed a retrospective analysis (1/2014–5/2019) of all ventral hernia repairs (n = 386) done in our institution as open sublay mesh reinforcement, partially requiring component separation (CS), receiving iNPWT in selected cases based on single surgeon experience. Pre‐ and perioperative data included patient and hernia characteristics as well as the employed mesh sizes. Postoperative follow‐up (median 38.5 months [interquartile range: 23.4, 53.3]) extended beyond patient dismissal and included the rate of re‐admission due to wound healing disorders. The primary outcome was the incidence of surgical site occurrences (SSO). Secondary endpoints included wound‐related readmissions, reoperations and recurrences. Patients were matched based on propensity scores in a 1:1 ratio. Propensity scores were calculated based on five preoperative variables, including sex, body‐mass‐index, American Society of Anesthesiology classification, recurrent hernia repair and operation technique, to identify significant parameters. The rate of SSO was 12% (n = 46) for all operated cases, and the rate of surgical site infection (SSI) was 8.8% (n = 34). In the subgroup of CS (n = 40), the rate increased to 15% (n = 6). The usage of iNPWT (n = 54) led to an in‐hospital SSO rate of 14.8% (n = 8) but increased to 33.3% (n = 18) when including the re‐admission rate. The SSI rate for the iNPWT cohort was 14.8% (n = 8) with a consecutive need for reoperation (Clavien‐Dindo IIIb) in 87.5% (n = 7). In the matched‐pair analysis, the hernia‐size and mesh‐size were the main risk factors for SSO. The use of iNPWT significantly reduced this statistical effect (p = 0.405). In a large and representative patient cohort, we were able to demonstrate that the advantage of iNPWT used after complex abdominal wall repair does not come first hand. Especially in the follow‐up, we found a relevant increase in wound healing problems after dismissal. To proof the benefit of iNPWT in these heterogeneous patients, we could identify hernia size and mesh size as individual risk factors that were nihilated by the use of iNPWT. We found it to be favourable to use iNPWT when mesh‐size exceeded 450 cm².

Postoperative quality of life is an important outcome parameter after treatment of abdominal aortic aneurysms. The aim of this retrospective single-center study was to assess and compare the health-related quality of life (HRQoL) of patients after open repair (OR) or endovascular treatment (EVAR), and furthermore to investigate the effect of incisional hernia (IH) formation on HRQoL. Patients who underwent OR or EVAR for treatment of an abdominal aortic aneurysm between 2008 and 2016 at a University Medical Center were included. HRQoL was assessed using the SF-36 questionnaire. The incidence of IH was recorded from patient files and by telephone contact. SF-36 scores of 83 patients (OR: n = 36; EVAR: n = 47) were obtained. The mean follow-up period was 7.1 years. When comparing HRQoL between OR and EVAR, patients in both groups scored higher in one of the eight categories of the SF36 questionnaires. The incidence of IH after OR was 30.6%. In patients with postoperative IH, HRQoL was significantly reduced in the dimensions “physical functioning”, “role physical” and “role emotional” of the SF-36. Based on this data, it can be concluded that neither OR nor EVAR supply a significant advantage regarding HRQoL. In contrast, the occurrence of IH has a relevant impact on the HRQoL of patients after OR.

Background: Primary hyperparathyroidism (pHPT) is the third most common endocrine disease, affecting predominantly postmenopausal women. About 85% of cases are caused by a solitary parathyroid adenoma which leads to a hypersecretion of the parathyroid hormone (PTH) and consequently to elevated serum calcium concentrations. Parathyroidectomy is the only curative treatment. While a very low recurrence rate of 0.4–1.3% was previously thought, recent long-term studies have shown significantly higher recurrence rates at longer follow-up intervals of more than 6 months to several years, posing new challenges for surgeons. In addition, laboratory dynamics may occur in the early postoperative period that cannot yet be adequately explained in terms of long-term outcomes. Therefore, the aim of this study was to evaluate the long-term outcome after parathyroidectomy for pHPT at the Department of General Surgery at the Rostock University Medical Center with regard to late recurrences. Methods: This retrospective long-term follow-up evaluated the postoperative course after parathyroidectomy for pHPT. Based on 111 patients who underwent surgery at the Department of General Surgery at the University Hospital Rostock between 2007 and 2017, 65 patients were followed for a median postoperative period of 41 months. Results: In addition to normocalcemic PTH fluctuations in the early postoperative period, which is a well-known phenomenon, the result shows an elevated calcium or PTH concentration during a follow-up of more than 10 years. These results may predict late recurrence. Furthermore, it is not the preoperative PTH and calcium, but rather the preoperative serum creatinine that plays a role in late follow-up, contrary to expectations. Conclusions: The results emphasise the importance of long-term follow-up of patients who have undergone parathyroidectomy and may help to guide the development of institutional postoperative surveillance.
