Added value of surgical interdisciplinarity- The Joel-Cohen's abdominal incision.

BACKGROUND: Surgical methods have profited from the exchange of knowledge among different specialties. Endoscopy which was introduced by gynecologists, surgeons, and internists is used now by all disciplines, and most of yesterday's laparotomies have now endoscopic alternatives. However, laparotomies are still needed, and there is no agreement among surgeons about what is the optimal abdominal incision. The Joel-Cohen incision which is used by gynecologists and obstetricians could become a valid alternative to the methods in use. METHOD: The Joel-Cohen Method, which was evolved for abdominal hysterectomy is described here in detail. Only two instruments are used to open the abdomen, usually with no need for hemostasis. CONCLUSION: The Joel-Cohen incision is suggested as a valid alternative for any emergency or elective surgical or urological abdominal operation. Its benefits are short operation time diminished blood loss and less need for analgesics.

Pepsin and oropharyngeal pH monitoring to diagnose patients with laryngopharyngeal reflux.

OBJECTIVES: The aim of this study was to compare the diagnostic accuracy of salivary pepsin with oropharyngeal pH monitoring using the Restech measurement system (Dx-pH) for the diagnosis of laryngopharyngeal reflux (LPR). STUDY DESIGN: Prospective cohort study. METHODS: Seventy patients with primary symptoms related to LPR underwent gastroscopy, high-resolution manometry, pH throughout 24-hour monitoring (MII-pH), and barium esophagography between October 2015 and May 2018. In addition, an ear, nose, and throat examination was performed, including assessment of Belafsky Reflux Finding Score (RFS). Clinical symptoms were evaluated with the Belafsky Reflux Symptom Index (RSI) and the Gastrointestinal Quality of Life Index (GIQLI). Simultaneous to MII-pH, pepsin determination and Dx-pH were performed. RESULTS: Of 70 patients, 41 (58.6%) subjects with a pathological DeMeester score showed higher mean values of pepsin (mean value: 216 ng/mL, 95% confidence interval [CI]: 172 to 260), compared to patients with a normal DeMeester score (mean value: 161 ng/mL, 95% CI: 115 to 207). Salivary pepsin showed a specificity of 86.2% and sensitivity of 41.5% for diagnosing LPR using the optimal cutoff value of 216 ng/mL. Furthermore, a significant correlation between the values of salivary pepsin and the RSI score was seen in patients with pathological results in MII-pH (r = 0.344; P = 0.046). However, elevated Dx-pH measurements showed no significant correlation with either MII-pH, RSI score, RFS score, or GIQLI score, or with the results of pepsin measurement. CONCLUSION: Pepsin measurement in saliva could be an alternative tool to assist office-based diagnosis of LPR, whereas Dx-pH does not seem to be an adequate test. LEVEL OF EVIDENCE: 2B Laryngoscope, 130:1780-1786, 2020.

Clinical feasibility of a new full-thickness endoscopic plication device (GERDx™) for patients with GERD: results of a prospective trial.

BACKGROUND: Previous studies suggest clinical effectiveness of endoscopic full-thickness plication in selected patients with gastroesophageal reflux disease (GERD). The aim of this study was to assess the clinical safety and efficiency of the GERDx™ device by evaluating clinical parameters, reflux symptom scores, and quality of life (QoL). METHODS: Prospective one-arm trial evaluating the outcome of forty patients with GERD subjected to endoscopic plication with the GERDx™ device. We included patients with at least one typical reflux symptom despite treatment with a PPI for > 6 months, pathologic esophageal acid exposure, hiatal hernia of size < 2 cm, and endoscopic Hill grade II-III. Evaluation of Gastrointestinal Quality of Life Index (GIQLI), symptom scores, esophageal manometry, and impedance-pH-monitoring were performed at baseline and at 3 months after surgery. (Trial Registration: ClinicalTrials.gov NCT 01798212.) RESULTS: There were no intraoperative complications. Four out of forty patients experienced postoperative complications requiring intervention. Seven of forty patients were subjected to laparoscopic fundoplication 3 months after endoscopic plication due to persistent symptoms and were lost to further follow-up. Thirty out of forty patients were available at 3-month follow-up. There was an improvement of the GIQLI score, from a mean of 92.45 ± 18.47 to 112.03 ± 13.11 (p < 0.001). The general reflux-specific score increased from a mean of 49.84 ± 24.83 to 23.93 ± 15.63 (p < 0.001), and the DeMeester score from a mean of 46.48 ± 30.83 to 20.03 ± 23.62 (p < 0.001). There was no significant change in manometric data after intervention. Three of thirty patients continued daily antireflux medication. CONCLUSIONS: Endoscopic plication with the GERDx™ device reduced distal acid exposure of the esophagus, reflux-related symptoms, and improved GIQLI scores with minimal side effects in a selected cohort of patients and may be a safe alternative in the treatment of GERD.

[Impact of medical TV series on surgical hospital patient's perception of reality]. / Einfluss von Arzt- und Krankenhausserien auf das Wirklichkeitsempfinden chirurgischer Krankenhauspatienten.

BACKGROUND: Medical TV series are very popular. Media research emphasizes that watching TV has an influence on patient's expectations and estimations concerning upcoming surgery. We analyzed these associations in our own patients. We suspected that reality as presented in the media and the actual reality of hospitals are not always conceived as two different worlds. METHODS: Over a 15-month period a standardized questionnaire was used to interview 162 in-house patients who had been admitted for an elective standard operation. They were interviewed 1-2 days prior to surgery and shortly before discharge from hospital. The questions aimed at their social situation and their TV viewing habits with special consideration of medical TV series. RESULTS: The knowledge of medical TV series is highly associated with a realistic assessment of these programs (p < 0.05). Furthermore, the knowledge of these programs is correlated with patient's unrealistic estimations of upcoming surgery. CONCLUSION: Medical TV series have a significant influence on surgical in-house patients. Patients with knowledge of many medical TV series believe that the medical setting in these shows is realistic. This can result in false estimations concerning real surgery.

Hybrid techniques and patients' safety in implementing transoral sublingual thyroidectomy.

PURPOSE: Cosmetic advantages and minimally invasive aspects become more and more important for patients undergoing thyroidectomy. We report on our personal experience and conceptual design in dealing with approaches to the thyroid gland, which we were the first to describe. We report on ideas and experiences concerning its implementation. METHODS: Our own experiences and considerations in the process of finding an endoscopic minimally invasive access in thyroidectomy are compared in a systematic review with the available literature on minimally invasive or endoscopic thyroid surgery. We describe our failures and risk assessment. RESULTS: Our analysis of the literature on minimally invasive thyroidectomy and our own experiences lead us to the conclusion that using different hybrid technologies during the implementation of endoscopic procedures in thyroid surgery can be helpful and could improve patients' safety. A combination of transoral endoscopic and non-transoral techniques might be a useful safer, but more traumatizing alternative for implementation. Several studies show the feasibility of the transoral access in thyroid surgery. We believe that the implementation of these new procedures as routine surgery in specialized centers must be carefully considered and discussed. CONCLUSIONS: The transoral access seems to be less invasive than other extracollar endoscopic accesses in thyroid surgery. For a sublingual single-access routine surgery, better instruments are needed. The vestibular access is possible with standard instruments. Using hybrid technologies for implementation should not be considered as a failure. The transoral thyroidectomy can be a safe method in the hand of experienced surgeons. We expect this hybrid technique to play a major part in further spreading endoscopic transoral thyroid surgery.

Minimally invasive endoscopic thyroid surgery using a collar access: experience in 246 cases with the CEViTS technique.

BACKGROUND: The arguments for applying minimally invasive techniques are, besides cosmetic results, reduced access trauma and less postoperative pain. In thyroid surgery, cosmetic aspects are gaining importance. Whether minimally invasive endoscopic thyroid surgery is less painful has not been shown yet. METHOD: In this study, we analyse the outcome of 246 patients who underwent cervical endoscopic video-assisted thyroid surgery (CEViTS) regarding the surgery itself, their postoperative pain and satisfaction with the procedure. RESULTS: CEViTS is routinely performed in our hospital. In this study, no postoperative bleedings that would have made a reoperation necessary occurred. All lobectomies could be completed endoscopically. In two cases, conversions (enlargement of the 5-mm incision to 25 mm) were necessary. Transient nerve palsy was registered in three patients (1.22%). One patient (0.41%) had a permanent palsy of the recurrent laryngeal nerve. In comparison to open surgery (n = 173 patients), the 246 CEViTS patients had a significantly lower pain level (p = 0.047). CONCLUSIONS: Cervical endoscopic video-assisted thyroid surgery (CEViTS) can be considered a safe, less traumatizing and useful minimally invasive procedure in endoscopic thyroid surgery.

Role of Pepsin and Oropharyngeal pH-Monitoring to Assess the Postoperative Outcome of Patients with Laryngopharyngeal Reflux: Results of a Pilot Trial.

BACKGROUND: The aim of this study was to evaluate the value of salivary pepsin and oropharyngeal pH-monitoring to assess the surgical outcome of patients with laryngopharyngeal reflux (LPR). MATERIALS AND METHODS: Twenty consecutive patients with LPR despite proton pump inhibitor treatment received laparoscopic antireflux surgery. Twenty-four hour esophageal pH-monitoring (multichannel intraluminal impedance monitoring [MII]-pH) and esophageal manometry (high-resolution manometry) data were documented preoperatively and at 3-month follow-up. An ears, nose and throat (ENT) examination was performed, including assessment of Belafsky Reflux Finding Score (RFS). Clinical symptoms were evaluated with the Belafsky Reflux Symptom Index (RSI) and the Gastrointestinal Quality of Life Index (GIQLI). Simultaneous to the MII-pH and collection of saliva samples, detection of oropharyngeal reflux events was performed. Treatment failure was defined as postoperative pathologic RFS or RSI score and improvement of GIQLI of <10 points, despite showing a normal DeMeester score. RESULTS: At baseline, all patients had a pathological ENT examination, RSI score, and MII-pH data. All patients showed postoperatively a normal DeMeester score (mean 6.39 ± 4.87). Five patients were defined as treatment failures with a change of pepsin concentration from median 157.0 (95% confidence interval [CI]: 0-422) to 180.7 (95% CI: 0-500). In patients defined as treatment success, median pepsin value decreased from 206.3 (95% CI: 89-278) to 76.0 (95% CI: 55-205); (P = .093). Oropharyngeal pH-monitoring data showed no significant change in both groups. CONCLUSION: Salivary pepsin could be a marker for treatment success, while oropharyngeal pH-monitoring seems to be inadequate in these terms. However, larger studies are required to reach firm conclusions.

Transoral thyroidectomy: limitations, patients' safety, and own experiences.

For patients undergoing thyroidectomy, the minimally invasive aspect and the cosmetic advantage of the procedure seem to be important factors in surgery. Studies in cadaver and animals have shown that different endoscopic techniques can be performed in a safe and successful way. In the evolution of thyroid surgery, for many endocrine surgeons, the transoral approach seems to be the next step. Even if such procedures are more and more frequently applied in patients, these procedures are far from being generally implemented in routine surgery. In this study, we report on our own experience and considerations in the process of finding a sublingual endoscopic transoral way to the endoscopic transoral thyroidectomy. We describe our failures, risk assessment and compare that with the available literature on transoral sublingual and vestibular thyroid surgery. The access itself needs to be further refined, and even more suitable and better adapted instruments need to be developed, so that optimal and safe results that meet all requirements on endocrine surgery can be achieved. A learning curve at the risk of patients' lives should be avoided. Furthermore, a combination of transoral endoscopic non-transoral techniques might be a useful safer, but more traumatising alternative for implementation. The sublingual access seems to be less invasive than the vestibular access. For a sublingual single-access routine surgery, better instruments are needed. Only in highly specialized centres for endocrine and endoscopic surgery, transoral thyroidectomy should be performed.

If time matters: a multicenter review of minimally-invasive hernia repair in 7176 cases.

BACKGROUND: In endoscopic hernia repair totally extraperitoneal approach (TEP) and transabdominal preperitoneal approach (TAPP) are seen as equivalent surgical techniques in quality, but not in procedure-time. METHODS: We compared the two most common procedures in endoscopic hernia surgery. Focusing on the duration of the surgical procedure, we analyzed 7176 endoscopic hernia operations in 25 hospitals retrospectively and compared it to the literature. RESULTS: In our study TEP (N.=2799) took on average 59 minutes, TAPP (N.=4377) took 67.5 minutes, thus with a significant difference (P=0.043). In high volume centres this difference was even bigger. As there are few consistent advantages of one of the procedures in general, the procedure' s duration becomes more important. CONCLUSIONS: If time is the main reason, the TEP procedure takes on average 8.5 minutes less time, so it can be more cost-effective.

Impact of Medical TV Shows on Preprocedural Fear of Surgical In-House Patients.

Background and Hypotheses: The growing number of medical television series and the increasing amount of time people spend watching TV will have an influence on what they expect from their treatment in a hospital. We suspect that reality as presented in the media and the actual reality of hospitals are not always conceived of as two different worlds. Many medical TV shows present dramatic, life-threatening operations much more often than they occur in reality. Patients who frequently watch such shows might be induced to believe that even routine operations are often dangerous, which could result in higher levels of fear before such an operation. We suspect then that there is a significant relation between preoperative levels of fear and TV viewing habits. METHODS: A standardized questionnaire was used to interview 162 in-house patients who had come to the hospital for an elective standard operation in a German hospital. They were interviewed 1-2 days prior to operation and shortly before discharge from hospital. The questions aimed at their social situation, their TV viewing habits with special consideration of medical TV shows, and the patients' preprocedural fear. RESULTS: The links between levels of education, age, and gender on the one hand, and viewing habits on the other, which have been shown in cultivation research, are supported by our findings. Approximately 50% reported a relevant anxiety level above 4 (on a scale of 0-10). There is a significant association between levels of fear and TV viewing habits. Thirteen subjects (8%) indicated that they suffered the highest imaginable degree of fear, all of them frequent watchers of medical TV shows. Frequent viewers of medical TV shows were definitely more scared than all other patients (p = 0.039). The preoperative level of fear was highest in the age group of under 40 years and significantly lower (p = 0.0042) in the age group of over 70 years. CONCLUSION: The assumed effects of cultivation with in-house patients caused by watching TV series could be shown to be statistically significant. Watching medical TV shows increases the patients' preoperative fear.

Endoscopic thyroidectomy: the transoral approach.

Transoral endoscopic thyroid surgery seems to be the logical consequence in the evolution of thyroid surgery. Animal and cadaver studies have shown that different endoscopic techniques can be performed in a safe and successful way. Presently, the minimally invasive aspect and cosmetic advantage seem to be the most important factor for the patients. However, even if these procedures are feasible in patients, the transoral access must still be considered as experimental. In this study then we aim at comparing the available literature on transoral thyroid surgery with our own experience in this field. The access itself needs to be further refined, and even more suitable and better adapted instruments need to be developed so that optimal and safe results that meet all requirements on endocrine surgery can be achieved and all requirements for endocrine surgery are met. The transoral thyroidectomy should only be performed in highly specialized centres for endocrine and endoscopic surgery. As an alternative, a combination with endoscopic non-transoral techniques-so called hybrid techniques-might be useful for our patients.

[Mastitis with abscesses caused by esophageal fistula]. / Abszedierende Mastitis durch eine Osophagusfistel.

Mastitis originating from a fistula from intramediastinal esophago-jejunostomy following gastrectomy is an extremely rare event. We report on a 79-year old woman who had undergone repeated surgery due to recurrent breast abscesses for more than a year. The patient's history showed gastrectomy and esophago-jejunostomy two years earlier, with subsequent undetected insufficiency of the anastomosis and inflammation of the breast. The reason for the recurrent breast abscesses was found intraoperatively to be due to a fistula which could be followed to the anastomosis. Histologically, vegetable tissue (food particles) was detected in the fistula specimen. Detailed assessment of the patient's history could have helped detecting the circumstances when the first breast abscess appeared. Exact preoperative diagnosis and accurate wound débridement could have revealed the real cause of the recurrent abscess formation much earlier.

The axillary access in unilateral thyroid resection.

BACKGROUND AND STUDY AIMS: With this study, we intended to find out if it is possible to avoid the typical scar after thyroid resection by using a 20 mm axillary access and a 3.5 mm incision in the jugulum. MATERIALS AND METHODS: We present the results of our proof-of-concept study with 12 patients. For this technique, a modified axilloscope and ultrasonic scissors were used, which permit a total resection of the unilateral thyroid. RESULTS: The feasibility of this endoscopic technique was shown by the successful operation of these patients with unilateral pathological findings. Furthermore, we showed that this technique allows to resect tissue up to a whole lobe while at the same time finding and identifying the recurrent laryngeal nerve and subsequently verifying the findings by using the neuro-monitoring system. CONCLUSIONS: This study shows that endoscopic thyroid surgery approximates the norms of endocrine neck surgery. The presented method is useful in thyroid surgery for patients with single nodules and a small thyroid gland.
