Safety and clinical outcomes of thoracoscopic segmentectomy in bilateral lung cancer: A single-center retrospective study / 中国胸心血管外科临床杂志

@#Objective     To assess the safety and clinical outcomes of segmentectomy in one- or two-staged video-assisted thoracoscopic surgery (VATS) for bilateral lung cancer. Methods    We retrospectively enrolled 100 patients who underwent VATS segmentectomy for bilateral lung cancer at the Department of Thoracic Surgery of Peking Union Medical College Hospital from December 2013 to May 2022. We divided the patients into two groups: a one-stage group (52 patients), including 17 males and 35 females with a mean age of 55.17±11.09 years, and a two-stage group (48 patients), including 16 males and 32 females with a mean age of 59.88±11.48 years. We analyzed multiple intraoperative variables and postoperative outcomes. Results     All 100 patients successfully completed bilateral VATS, and at least unilateral lung received anatomical segmentectomy. Patients in the one-stage group were younger (P=0.040), had lower rate of comorbidities (P=0.030), were less likely to have a family history of lung cancer (P=0.018), and had a shorter interval between diagnosis and surgery (P=0.000) compared with patients in the two-stage group. Wedge resection on the opposite side was more common in the one-stage group (P=0.000), while lobectomy was more common in the two-stage   group. The time to emerge from anesthesia in the one-stage group was longer than that in the first and second operations of the two-stage group (P=0.000, P=0.002). Duration of surgery and anesthesia were similar between two groups (P>0.05). Total number of lymph node stations for sampling and dissection (P=0.041) and lymph nodes involved (P=0.026) were less in the one-stage group. Intraoperative airway management was similar between two groups (P>0.05). The one-stage group was associated with lower activities of daily living (ADL) scores. Conclusion     Segmentectomy is safe in one- or two-staged VATS for bilateral lung cancer, including contralateral sublobectomy and lobectomy. Duration of surgery and perioperative complications are similar between two groups, but the one-stage group is associated with lower ADL scores. On the basis of comprehensive consideration in psychological factors, physical conditions and personal wishes of patients, one-staged sequential bilateral VATS can be the first choice.

Surgical strategy in treating synchronous sporadic bilateral renal cell carcinoma / 中华泌尿外科杂志

Objective To evaluate the impact of different surgical approach on postoperative renal function in patients with synchronous sporadic bilateral renal cell carcinoma ( SSBRCC) .Methods The medical records of 28 patients with SSBRCC were reviewed.Of all these cases, 21 patients were male and 7 were female, and the mean age was 51 ( 25-63 ) years.None of these cases had family history of renal carcinoma.The treatment and other clinical data were analyzed retrospectively.Results All of the 28 patients underwent bilateral surgeries.Single procedures were performed on 16 patients, of which, one underwent bilateral radical nephrectomy ( RN) , 8 bilateral nephron-sparing surgery ( NSS) and 7 unilateral NSS combined with contralateral RN.Staged procedures were performed on 12 patients, of which bilateral NSS was on 5 patients (NSS-NSS group), NSS followed by RN (NSS-RN group) on 3 patients and RN followed by NSS ( RN-NSS group) on 4 patients.In term of postoperative renal function preservation for SSBRCC patients, the standard NSS was better than RN.Between different staged procedures, NSS-NSS was the preferred choice, and the NSS-RN was superior to the RN-NSS.Conclusions In term of preservation of postoperative renal function, the staged procedures were recommended, and NSS was preferred in the first stage.In deciding the second stage surgical approaches, the surgeons should take the renal function preservation and the tumor size into consideration.

The Effect of Unilateral and Bilateral Superior Rectus Recession for Dissociated Vertical Deviation(DVD)

Dissociated vertical deviation(DVD)is a kind of vertical strabismus of an upward drift of a nonfixating eye, and requires operation when it is cosmetically unacceptable. The authors compared the results of unilateral superior rectus recession with those of bilateral recession in the treatment of DVD, and analyzed the effects and complications of the superior rectus recession. The charts of 58 patients(94 eyes)who underwent superior rectus recession for DVD were retrospectively reviewed, and minimum follow-up was 6 months after operation. In 22 patients, the recession was performed unilaterally, and in 36 patients bilaterally. Satisfactory alignment under 9 PD was obtained in 77.3%of the unilateral cases and 77.8%of the bilateral cases. DVDs developed in unoperated eye in 9 unilateral cases. Graduated superior rectus recession was a quite predictable and effective procedure in the treatment of DVD. In unilateral surgery, it is important to keep in mind that the unmasking of DVD in the fellow eye can occur, but unilateral surgery may be indicated if only when the obvious deviation is diagnosed preoperatively in one eye.

A Comparison of Clinical Results in Unilateral and Bilateral Cataract Surgerys

PURPOSE: This study compares the outcomes of unilateral cataract surgery to those of bilateral cataract surgery in patients with cataract of both eyes. METHODS: Among a total of 153 patients, 61 underwent unilateral surgery and 92 bilateral surgery. RESULTS: The unilateral and bilateral surgeries were similar in demographic and ocular characteristics including visual acuity and visual function-14, except patient-reported factor, such as trouble with vision at baseline. The patient-reported factor was more serious in bilateral surgery than in unilateral surgery. The changes of three outcomes were associated not with unilateral eye or bilateral eye surgery, but with each baseline condition. CONCLUSION: The patient-reported factors such as symptom score, trouble with vision were the significant outcomes to decide unilateral or bilateral surgery in patients with cataract of both eyes. The result of unilateral or bilateral surgery did not affect the outcomes of cataract surgery after 12 months.

Comprehensive survey of 374 patients (463 eyes) undergoing cataract extraction, (with emphasis on the influence of bilaterality of surgery)

This survey of 374 patients, of which 47 underwent bilateral cataract surgery in one sitting and 42 in different sittings reveal that there is no differences in the incidence of complications following cataract extraction. The apparent slight discrepancies are more due to the inequality of patient reaction and variability of situations before surgery rather than from the unilaterality and bilaterality of surgery itselfThe advantages of simultaneous surgery to name a few, are (1) less mental trauma, (2) shorter hospitalization period, (3) less hospital and surgery expenses, (4) much wider field of vision and (5) earlier return to workThis study definitely disproves the contention that there are more complications when 2 eyes are done simultaneously than when the surgery is done with some time intervalIt may therefore, be safely concluded that bilateral cataract surgery may be done safely in one sitting if the proper presurgical and postoperative care are followed faithfully.
